Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to improvements in a solvent filtration device and a dry cleaning device.

[0002]

[Prior art]

 Dry cleaning machines consist of a base tank, solvent circulation pump, solvent filtration filter, carbon tank, clothes washing drum, button trap, base tank, etc. for the cleaning solvent. The clothes are washed while circulating.

At this time, one method in a solvent filtration device is to attach diatomaceous earth (soil having a myriad of holes) as a filtering agent to a screen made of wire mesh or the like, form a filtration layer, and form a soiled solvent. In this method, the solvent does not pass when the amount of dirt attached to the filtration layer reaches a certain amount, so that the circulation of the solvent is stopped and the screen is shaken, and the filtration on the screen is performed. The dirt is removed by sieving the agent, and a new diatomaceous earth filter layer is formed on the screen again to filter the solvent again.

[0004] Another type is a cartridge filter system in which a solvent is filtered by an element, and sludge generated by washing the clothes with fiber waste and dirt accumulates outside the filter paper of the element, and when the accumulated dirt reaches a certain amount, the solvent passes. In this method, the circulation of the solvent is stopped, and the solvent is filtered while replacing the element with a new one.

[0005] The former method, a filter using diatomaceous earth, was installed on early machines when dry cleaning machines began to appear because running costs were not required. Diatomaceous earth containing dirt from cleaning is sticky and has a bad smell due to dirt. The latter type, the cartridge filter type, has a high running cost, but is easy to handle, and is currently the mainstream of filtration filters for dry cleaning machines.

[0006] The present applicant has proposed a solvent filtering apparatus and a dry cleaning apparatus in which the inflow of the solvent and the removal of the filtering agent are performed in the latter manner by the reverse action, which is disclosed in Utility Model Registration No. 3050880. Registered.

[0007]

[Problems to be solved by the invention]

 The above proposal is excellent in that odors and solvent dirt are drastically reduced because dirt and sludge are not discharged to the outside of the solvent filtration device, and therefore dirt and sludge are not mixed into the base tank. Although effective, the present invention is an improvement proposal that omits a large number of through-holes drilled in a tube shaft employed as a means for feeding a solvent into the interior of the element.

[0008]

[Means for Solving the Problems]

The lever receiving brackets are arranged opposite to each other so that the element tightening lever with the element tightening handle is engaged and fastened, while the solvent case of the solvent inlet port side has an appropriate size solvent in the center. An element receiving seat provided with an introduction hole is provided, and a paper or nonwoven fabric element having an outer peripheral surface formed in a fold shape is provided between the element receiving seat and the element tightening handle of the opening / closing lid. Engage the element tightening lever with the lever receiving bracket, and use the element pressing bracket so that there is a certain gap between it and the inner wall surface of the case. With fixed and solvent passed outward from the inside of the element a is a solvent filtration apparatus 及 beauty dry cleaning apparatus characterized by being configured to retrieve from the gap between the case.

Reference numerals 5a and 5b denote a pair of lever receiving members disposed opposite to the inner peripheral edge of the opening / closing lid 4 of the cylindrical cartridge case 1, and reference numeral 6 denotes a tightening handle 7 which engages with the lever receiving members. The element tightening lever is adapted to be tightened and fixed to an element to be described later by using an element presser 8.

Reference numeral 9 denotes an element receiving seat in which a solvent introduction hole s of an appropriate size is formed in the center of the cartridge case 1 on the solvent inlet side.

Reference numeral 10 denotes an element made of paper or nonwoven fabric having an outer diameter slightly smaller than the inner diameter of the case 1 and having an outer peripheral surface formed in a fold shape. The cartridge 10 is provided inside the case 1 by using an element guide rail (not shown). As shown in FIGS. 2A and 2B, the case 1 is inserted from the side of the opening / closing lid 3 between the element receiving seat 9 on the solvent inflow port 2 side and the opening / closing lid 3 so as to have a certain gap w on the inner wall of the case 1. The metal fitting 8 and the tightening handle 7 are used for fastening and fixing. At this time, a packing 11 is provided between the element receiving seat 9 and the element press fitting 8 to prevent solvent leakage.

In the illustrated example, the elements 10 are stored in two rows in the cartridge case 1. However, the rows can be provided in an appropriate row, and the packing 11 is similarly interposed between adjacent elements. I do. In the drawing, reference numeral 12 denotes a discharge valve for discharging the residual filtered solvent in the cartridge case 1 into the base tank when the solvent filtering device is incorporated in the dry cleaning device.

FIG. 3 is a schematic explanatory view in which the above-mentioned solvent filtration device is attached to a dry cleaning device, wherein 13 is a base tank, 14 is a solvent pump, 15 is a carbon tank, 16 is a clothes washing drum, and 17 is a clothes washing drum. A button trap, 18 is a liquid supply switching valve, 19 is a drain valve, and 20 is an overflow pipe.

When the pump is turned on, the solvent pump 14 is driven to pump up the solvent from the base tank 13, the solvent is filtered by the element 10 of the solvent filtration device, and the carbon tank is turned on. After further deodorizing and decoloring at 15, it is returned to the base tank 13 via the liquid supply switching valve 18, pumped again by the solvent pump 14, and filtered by the element 10 in the solvent filtration device. Waiting is performed while repeating the action.

Next, when clothes to be washed are put into the drum 16 and the operation switch is turned on, the liquid supply switching valve 18 is closed and the solvent is sent to the washing drum 16, and washing is performed while rotating in the drum together with the clothes. After that, the solvent is discharged together with dirt (fiber swarf or sludge) by the overflow pipe 20, a large dust is removed by the button trap 17, and the circuit returns to the base tank 13. Thus, the solvent returned to the base tank 13 is again pumped by the solvent pump 14 and is repeatedly filtered by the element 10 in the solvent filtration device, and the filtered sludge adheres to the surface of the element. Will be done.

When the cleaning is completed, the liquid supply switching valve 17 is opened to stop the flow of the solvent into the cleaning drum 16, and the drain valve 19 is opened to allow the solvent in the cleaning drum 16 to return into the base tank 13. Further, the washing drum is rotated at a high speed, and the solvent contained in the clothes is returned into the base tank 13.
