Description

Dust-proof device for unloading trolley of belt conveyor

Technical field:

The utility model relates to a dust-proof device of a dressing plant, in particular to a dust-proof device for a discharge trolley of a belt conveyor.

Background technique:

At present, the unloading trolley of the belt conveyor in the mineral processing plant will fly a large amount of dust during unloading, as shown in Figure 1 and 2. The current solution is to install high-pressure water mist nozzles on the entire belt conveyor corridor. Fog is used to reduce dust, but because the high-pressure water mist nozzle is often easily blocked, it is less used now, and the dust prevention of the unloading trolley of the belt conveyor is still an unsolved problem.

Utility model content:

The purpose of this utility model is to address the above-mentioned shortcomings, to provide a dust-proof device for the unloading trolley of the belt conveyor, which is to modify the funnel of the unloading trolley of the belt conveyor, which can greatly reduce the number of places on the hopper of the unloading trolley of the belt conveyor in the mineral processing plant. Flying dust can achieve dust reduction and dust prevention. The device is simple to manufacture, practical and easy to implement.

The utility model is realized in the following way: a dust-proof device for an unloading trolley of a belt conveyor, which is characterized in that a plow-type funnel is respectively installed at the outlet of the two ore discharge funnels of the unloading trolley, each A plow funnel is covered by two rubber plates covering the long strip holes. One side of each rubber plate is fixed on the top surface of the mine bin with bolts and pressure plates, and supports are installed in the long strip holes under the rubber plates. Mesh divider of rubber sheet.

The plow funnel is located directly above the elongated hole on the top surface of the mine bin.

The mine discharge funnel has a head guard at the top belt wheel.

A pressure wheel combination device for pressing the rubber plate can be installed on the rubber plate surface of the covered plow funnel. The pressure wheel combination device includes a longitudinal bar and a horizontal bar. The upper part of the longitudinal bar is connected with the horizontal bar, and the lower part has a rotatable Wheels, one end of the horizontal bar is fixedly connected with the funnel, and the vertical bar can be adjusted up and down relative to the horizontal bar.

It is more appropriate to install 2 to 4 pressure wheel combination devices for each plow funnel described.

Detailed ways:

Description will be given in conjunction with accompanying drawings and embodiments thereof.

Embodiment 1 of the present utility model: as shown in the figure, the dust-proof device of the unloading trolley of the belt conveyor is to improve the ore discharge funnels on both sides of the unloading trolley 1 of the present belt conveyor. The two lower outlets 7 of the mine funnel 2 are each made of a plow funnel 9, and two elastic rubber plates 10 are respectively installed on the two elongated holes 6 on the top surface of the mine bin, and the two rubber plates Fix it on the edge of the strip hole with bolts and pressure plates to cover the strip hole, and the rubber plate should also cover the plow funnel to prevent dust from flying out.

The middle of the plow funnel is usually square, and the two ends are like oblique corners. The corners of the corners are rounded 12 transitions. From the square in the middle to the corners on both sides, the rounded transition gradually increases, so that the corners can be avoided. The rubber plate also makes the sealing effect better, and there are rounded corners 13 at the ends of the edges and corners, which can also avoid scratching the rubber plate. It is better if the height of the plow funnel is greater than or equal to the standing height of the rubber plate, and the standing height of the rubber plate is related to the width of the two long strip holes on the top of the mine bin. It is more advantageous when the length of the plow funnel is longer, but when unloading When the material trolley walks to the end, the longer plow funnel will block the pedestrian aisle, and the total length of the plow funnel is generally 1 to 3 meters more favorable.

In order to prevent the two rubber sheets from collapsing in the elongated holes, a mesh partition 5 is installed in the entire elongated hole, which prevents the rubber sheets from collapsing and does not affect the material 4 from falling into the mine bin 3. There is a steel plate 11 on the bottom surface of each rubber plate or supported by the floor surface. The picture shows that the two forms of steel plate support and floor surface support are used at the same time. The rubber plate supported by the steel plate is fixed with a pressure plate and a row of bolts. And the rubber plate supported by the floor surface is fixed with a pressing plate and a row of expansion bolts, and the pressing plate can be made of flat steel material.

When the unloading trolley moves horizontally, the plow funnel that walks along with it lifts up the rubber plate to walk, and the raised rubber plate always covers the plow funnel and the long holes, preventing dust from flying out, so as to achieve dust reduction and dust prevention. Purpose. At the same time, a small amount of dust will fly out at the tape wheel at the top of the discharge trolley funnel, so a head guard 8 can be installed to further reduce the dust flying out from the top.

Embodiment 2: The device proposed according to the utility model can also be equipped with a pressing wheel combination device on the basis of the method 1, see Fig. 7 and Fig. 8 . The pressing wheel combination device includes a longitudinal rod and a horizontal rod, and its function is to press the rubber plate when the dust is very dry and the plow funnel covered by the rubber plate is not too tight, so as to make the plow funnel covered by the rubber plate tight and prevent the dust from Fly out of the gap. The vertical bar 14 can be adjusted up and down, and the horizontal bar 15 is fixed on the plow funnel. The number of pressure wheel combination devices installed on each plow funnel is generally 2 to 4, which are lightly pressed on the rubber plate surface of the covered plow funnel respectively, and the number is subject to good sealing.
