1 is a schematic flow chart showing the operation of a dust volume reduction system according to an embodiment of the invention. Please refer to FIG. 1 , the dust reduction system 100 of the embodiment includes a The dust collector 105, a feeding drum 110, a first valve member 120, a compression module 130, a filter module 140, a second valve member 150, a discharge drum 160, a truck cleaning hopper 170 and a water washing machine Device 180.

The dust collector 105 is used to filter dust generated after an industrial process such as Chemical Vapor Deposition (CVD). After the dust is filtered by the dust collector 105, it is sent to the feeding drum 110. After the dust in the feeding drum 110 is accumulated to a certain capacity, the first valve member 120 is opened to cause the dust in the feeding drum 110 to be compressed to be compressed. Inside the membrane group 130. The dust is compressed into a closely packed powder state in the compressed film group 130, and then falls into the discharge drum 160. When the amount of powder cake in the discharge drum 160 reaches a certain level, the powder cakes will fall into the truck cleaning hopper 170 to leave the dust reduction system 100.

In addition, the filter module 140 is disposed on one side of the compression module 130. When the dust is compressed, the gas mixed in the dust also passes through the filter module 140 and exits the dust reduction system 100. In addition, the dust reduction system 100 can optionally configure the water washing device 180, and the filter module 140 is connected to the water washing device 180, so that the gas passing through the filter module 140 passes through the water washing device 180 to periodically remove the toxicity of the gas to meet the specification. It is then discharged to the outside.

The detailed structure of the dust volume reduction system of this embodiment will be described in detail below. 2 is a schematic view of a feed bucket of the dust reduction system of FIG. 1. Referring to FIG. 2, the dust volume reduction system 100 of the present embodiment further includes a flexible pipe member 112, a hammer body 114, and a dust height gauge 116. The flexible pipe member 112 is disposed on the inner side wall of the feed drum 110, and the hammer body 114 is coupled to one end of the flexible pipe member 112. Dust height gauge 116 The utility model is disposed in the feeding drum 110 and electrically connected to the first valve member 120. The dust height gauge 116 is used to measure the dust height in the feed bin 110, for example, a powder level gauge, but the type of the dust height gauge 110 is not limited thereto. When the dust height exceeds a certain value, the first valve member 120 is opened to allow dust to enter the compression module 130 from the feed tub 110.

Since the dust falls from the dust collector 105 to the feed tank 110, it will be distributed in a bell shape in the feed drum 110, that is, the dust will have a middle high and a low circumference distribution state. As a result, the dust height gauge 116 misjudges the amount of dust in the feed bin 110. In the present embodiment, the soft tube 112 is disposed on the inner side wall of the feed tub 110 and the hammer 114 is connected to one end of the flexible tube 112. When the other end of the flexible tube 112 is continuously vented and deflated, the flexible tube The body 112 will be horizontally straightened and sagging in the feed bucket 110 to assume a swaying state, so that the hammer 114 hits the inner side wall of the feed tub 110. In this way, the higher dust located in the center of the feed drum 110 can be slid down, so that the dust in the feed drum 110 is more evenly distributed to avoid misjudgment of the dust height gauge 116. The dust level in the drum 110 is also high, and the dust in the feed tank 110 is also arranged more closely to accommodate more dust.

The first valve member 120 is located between the feed barrel 110 and the compression module 130. When the dust level in the feed barrel 110 reaches a certain value, the first valve member 120 is automatically opened to cause the dust to fall into the compression module 130. 3 is a schematic illustration of a first valve member of the dust volume reduction system of FIG. 1. Referring to FIG. 3, the first valve member 120 includes an annular side wall 122. The annular side wall 122 surrounds a dust passage C1. The dust passes through the dust passage C1 and falls to the compression module 130. At least one gas passage C2 is formed on the annular side wall 122 It is connected to and connected to the dust passage C1. In the present embodiment, the plurality of gas passages C2 are evenly distributed on the annular side wall 122 and communicate with the dust passage C1. Since the first valve member 120 is switched between opening and closing, the first valve member 120 may be caught by the dust and cannot be smoothly opened and closed. In the present embodiment, the operator can ventilate the gas passage C2 in turn to allow gas to be ejected from the gas passage C2 from the different directions to the dust passage C1 to blow away the dust plugging the first valve member 120.

4 is a schematic view of a cavity, a compression module, a filter module, and a discharge barrel of the dust volume reduction system of FIG. 1. Referring to FIG. 4, the compression module 130 includes a cavity 132 and a compression portion 134. When the first valve member 120 is opened, the feeding barrel 110 is connected to the cavity 132 of the compression module 130, so that the dust falls into the compression. The cavity 132 of the module 130 is inside. The compression portion 134 is, for example, a piston that is movable in the direction of the arrow within the cavity 132 to change an accommodation space S1 in the cavity 132. That is, the size of the accommodation space S1 varies depending on the relative position of the compression portion 134 within the cavity 132. The compression unit 134 compresses the dust in the cavity 132, and as the compression unit 134 moves, the accommodation space S1 is gradually reduced, and the granular dust is compressed into a cake shape or a block shape. In the present embodiment, a pressure sensor 136 can be disposed on the compression portion 134. When the pressure sensor 136 reaches a predetermined value, it indicates that the dust has been compressed to a sufficient degree of compactness.

As shown in FIG. 4 , the discharge bucket 160 is disposed at the bottom of the cavity 132 , and the second valve member 150 is disposed between the cavity 132 and the discharge bucket 160 . The second valve member 150 is electrically connected to the pressure sensor 136. When the pressure sensor 136 reaches a preset value, the second valve member 150 is opened, so that the compressed cake-like dust falls into the discharge. Bucket 160.

In addition, the discharge barrel 160 can be configured with a weight sensor (not shown) or a height sensor (not shown), and when the cake dust in the discharge barrel 160 reaches a sufficient weight or height, The cake dust within the drum 160 is transferred to the truck cleaning hopper 170 to exit the dust reduction system 100. In the present embodiment, after the dust is passed through the dust reduction system 100, the volume can be reduced to one quarter of the original, and the transportation amount of the truck can be effectively increased to reduce the transportation cost. Of course, the amount of dust volume reduction is not limited by this, and the operator can adjust the amount of dust volume reduction according to the condition of reducing the volume required.

In addition, in general, toxic gases are usually mixed in the dust, and the dust reduction system 100 of the present embodiment also provides a filter module to filter these toxic gases. FIG. 5 is a schematic diagram of a filter module filtering gas of the dust volume reduction system of FIG. 1. FIG. Referring to FIG. 4 and FIG. 5 simultaneously, the filter module 140 is disposed on a side of the cavity 132 relative to the compression portion 134. When the compression portion 134 moves in the direction of the filter module 140 in the cavity 132, it is mixed in the dust. The gas is pushed by the compression portion 134 to pass through the filter module 140.

In the present embodiment, the filter module 140 includes a filter material 142 and a frame 146. In FIG. 5, in order to clearly show the relationship between the components, the frame 146 is hidden on the left and right sides of the filter material 142, in fact, the frame The 146 will be in a single letter shape, surrounding the upper, lower, left and right sides of the filter material 142. The filter material 142 is located within the frame 146 for providing support when the compression portion 134 pushes the filter module 140. The filter medium 142 includes a support material such as polypropylene or polytetrafluoroethylene, for example, a filter material such as glass fiber or carbon fiber for filtering gas from the dust, and for example Activated carbon, catalyst or alkaline material used to react with toxic gases.

For example, an acidic toxic substance such as cerium oxide or cesium tetrafluoride is mixed in the dust, and if inhaled into the human body, it may cause a respiratory disease such as pneumoconiosis. If it is desired to filter out this material, a basic substance can be selectively applied to the filter medium 142 such that such acidic toxic substances are neutralized upon filtration. Of course, the type of material contained in the filter medium 142 can correspond to the substance to be filtered, and is not limited thereto.

A more detailed description of the filter module 140 will be described with reference to Figures 6A-6C. 6A-6B are schematic views of different perspectives of the filter module of the dust volume reduction system of FIG. 1. 6C is a schematic illustration of the frame of the dust volume reduction system of FIG. 1. Referring to FIG. 6A to FIG. 6B , in the embodiment, as shown in FIG. 5 , the filter medium 142 includes two filter layers 144 , and a filter space S2 is formed between the two filter layers 144 . In FIG. 6A, the portion of the frame 146 above and to the left and right sides of the two filter layers 144 is hidden. In fact, the frame 146 is in a letter shape, surrounding the upper, lower, left and right sides of the two filter layers 144. The two filter layers 144 are sealed to the surrounding frame 146 so that the gas mixed in the dust can only enter and exit the filter space S2 by the filter layer 144 without the gap between the two filter layers 144 and the surrounding frame 146. . Also, one of the filter layers 144 is hidden in FIGS. 6A and 6B to clearly show other components. The filter layer 144 has an air hole 144a communicating with the cavity 132 and the filter space S2 such that gas in the cavity 132 can pass through the filter layer 144.

In the present embodiment, in addition to the frame 146 positioned above and below the filter medium 142 to fix the filter material 142, a portion of the frame 146 is located on the front side of the filter material 142, that is, between the filter material 142 and the compression portion 134 to provide a compression portion. 134 Supportability when pushing the filter module 140. 6C shows a first surface 148 of the frame, the first surface 148 being the surface of the frame 146 closest to the compression portion 134, the first surface 148 having a plurality of holes 148a, and the filter material 142 being exposed to the holes 148a in the frame 146. . When the compression portion 134 pushes the dust, the dust abuts against the first surface 148 of the frame 146 and the filter material 142 exposed to the hole 148a. Since a part of the dust may adhere to the surface of the filter layer 144 which is closer to the compressed portion 134, although the particle size of the dust is larger than the pores of the filter layer 144 and does not enter the filter space S2, it is stuck in the filter layer 144. The dust on it makes it difficult for gas to pass through the filter layer 144.

To avoid this, the frame 146 includes at least one vent 149. In the present embodiment, the upper and lower frames 146 each include a plurality of symmetrically designed vents 149 that communicate with the filter space S2 between the two filter layers 144. In this embodiment, after the operation of the compression module 130 is temporarily terminated, the operator can pass the gas into the vent 149 of the frame 146 to allow the gas to enter the filtering space S2, since the filtering layer 144 may be cloth-like, Flexibility, when the filtering space S2 between the two filter layers 144 is inflated, the two filter layers 144 will expand outward and away from each other. Then, the operator can extract the gas in the filtering space S2 and make the two filtering layers 144 retracted and approached each other. Inflating and pumping in such a reciprocating manner, the two filter layers 144 are vibrated, and the dust stuck on the filter layer 144 is shaken off. In this way, when the compression module 130 performs the next operation, the gas in the dust can smoothly pass through the filter layer 144.

In addition, as shown in FIG. 6A and FIG. 6B, the filter layer 144 includes different parties. A plurality of first blocks 144b and a plurality of second blocks 144c extending and alternately connected. The total area of each of the first block 144b and each of the second blocks 144c is larger than the projected area of each of the first block 144b and each of the second blocks 144c on the first surface 148. In contrast to the fully planar filter layer 144, in this embodiment, the filter layer 144 provides a larger filter area by the first block 144b and the second block 144c extending in different directions. In other embodiments, the manner of increasing the filtration area may be a wrinkle-like surface or the like, and is not limited to the above.

In the present embodiment, the gas passing through the filter material 142 can be directed to the water washing apparatus 180 to further remove harmful gases. However, in other embodiments, if the gas after passing through the filter material 142 has reached a non-toxic standard, it can be directly discharged to the outside without passing through the water washing device 180.

In summary, the dust reduction system of the present invention provides an automated dust reduction and filtration gas flow. Briefly, when the dust enters the feeding bucket, the soft pipe fittings located in the feeding drum are periodically filled and deflated so that the hammer body knocks the wall of the feeding bucket instead of manually knocking the wall of the feeding bucket, so that the dust height is The meter can measure the exact height of the powder. In addition, the gas passage of the annular side wall of the first valve member is vented to smoothly clear the dust passage to allow the first valve member to be smoothly opened without manual disassembly. Therefore, when the dust in the feed barrel reaches a sufficient height, the first valve member automatically opens to cause the dust to fall into the cavity of the compression module, and then the compression portion squeezes the dust located in the cavity to reduce the volume of the dust. When the pressure sensed by the pressure sensor of the compression module reaches a preset value, the second valve member will automatically open, and the compressed cake or block dust will fall directly into the discharge barrel. When the dust in the discharge bucket reaches a sufficient weight At or altitude, the compressed dust is transferred to the truck clearing hopper to leave the dust reduction system. In addition, during the operation of the compression module, the toxic gas mixed in the dust passes through the filter module as the compression portion moves, is filtered or neutralized, and then optionally passes through the water washing device to perform the toxic gas. After the second treatment, it is discharged to the atmosphere.
