Abstract
The utility model discloses an automatic precipitation cleaning device of a disk vacuum filter, which belongs to a cleaning device of a disk vacuum filter. One end of each cleaning handle is fixed with an elastic cleaning board, and the other end is hooked on a fixing seat of channel steel or angle steel with a long hole. A double-head bolt is used as a cleaning device which clamps an adjustable element of a filter disk of a vacuum filter. When the automatic precipitation cleaning device is used, the clamping force and the distance of the cleaning handles which are arranged at both sides of each filter disk in pairs to the filter disk are adjusted by loosening the double-head bolt, and the abrasion loss of the cleaning board is randomly compensated. The utility model has the advantages that when the filter disk of the vacuum filter is operated, the cleaning device can forcibly scrape fine ore slurry and foam with higher water content, which exist at the connection root of the filter fan of the filter and a hollow shaft and can not be dewatered in vacuum, into a stock groove by the self-gravity and the clamping force of the cleaning device. Therefore, the automatic precipitation cleaning device can prevent the stocks from entering flotation concentrate products.
Description
Technical field
The utility model relates to the clearing apparatus of coal preparation plant's disc vacuum filter.It specifically is the automatic precipitation clearing apparatus of a kind of disc vacuum filter.
Background technology
There is not vacuum in the certain circumference range of root that disc vacuum filter filter fan is connected with air-cored axis, after making that concentrate slurry that the moisture be adsorbed on filter fan root is higher and foam reach certain thickness, can't be forced to scrape by discharging cell wall steel plate through vacuum dehydration, and directly enter in the floatation clean coal product, cause increasing of floatation clean coal product moisture.At present, for reducing the floatation clean coal product moisture, general using manually will be shoveled back feed chute without the coal slurry and the foam of dehydration, but because this filter has a plurality of filtration disks, do continuous running with certain speed, relying on manually is to reach the effect of not stopping a moment, cleaning out synchronously.
Summary of the invention
The utility model provides a kind of disc vacuum filter automatic precipitation clearing apparatus, and purpose is that higher concentrate slurry and the foam of avoiding being adsorbed on filter fan root of moisture enters in the floatation clean coal product.
The utility model is with following technical scheme: the automatic precipitation clearing apparatus of a kind of disc vacuum filter, comprise by the elasticity cleaning board be connected the cleaning handle formed, cleaning is being installed on the both sides that each filters disk in couples, the cleaning board of cleaning handle is close to the connection position of filtering disk and air-cored axis, one end and the elasticity cleaning board of the connection handle of cleaning handle are fixed together, and the other end is hooked on the holder; Connect on also be equipped with and regulate cleaning to the clamping force of filtering disk and the stud of spacing.Can regulate cleaning clamping force and spacing by the stud degree of tightness in the use to the filtration disk, and the wear extent of random back-off cleaning board.
The utility model it can be when vacuum filter filters disk running, need not any power, rely on the deadweight and the clamping force of clearing apparatus, automatically the filtration machine filter is fanned in the certain circumference range of root that is connected with air-cored axis and do not had vacuum, and be adsorbed on can't forcing to scrape to get back in the feed chute of filter fan root through the concentrate slurry and the foam than high-moisture of vacuum dehydration, stop this part concentrate slurry and foam and enter in the floatation clean coal product than high-moisture.
The beneficial effects of the utility model are: it can be when vacuum filter filters the disk running, need not any power, rely on the deadweight and the clamping force of clearing apparatus, automatically the filtration machine filter is fanned in the certain circumference range of root that is connected with air-cored axis and do not had vacuum, and the concentrate slurry and the foam than high-moisture that can't pass through vacuum dehydration that are adsorbed on filter fan root are forced to scrape to get back in the feed chute, stop this part material and enter in the floatation clean coal product, thereby reduce floatation clean coal moisture.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a vertical view of the present utility model.
1. filter disks among the figure, and 2. cleaning board 3. connects, 4. connects band steel, 5. holder, 6. stud, 7. nut, 8. feed chute, 9. blowpit, 10. air-cored axis, 11, cleaning range.
The specific embodiment
As shown in Figure 1, clearing apparatus comprise by cleaning board 2 be connected the cleaning handle of forming to 3.Connection is fixed together 3 one with cleaning board 2, and the other end is hooked in fixing the seat on 5 with connecting band steel 4, and the making of holder 5 usefulness channel-section steels has above for the slotted hole that connects band steel 4 hooks.Cleaning board 2 usefulness non-metallic elastic materials are made.Stud 6 is done cleaning clamping the regulating element that filters disk 1, can be in the use by the degree of tightness of stud 6 and nut 7, be adjusted to being installed on each cleaning of filtering the disk both sides to filtering the clamping force and the spacing of disk 1, and the wear extent of random back-off cleaning board.
When filtering disk 1 running, need not any power, rely on the deadweight and the clamping force of clearing apparatus, automatically filter in root cleaning range 11 circumference range that the machine filter fan is connected with air-cored axis 10 do not have vacuum and the scraping than the concentrate slurry of high-moisture and foam pressure of vacuum dehydration of can't passing through that be adsorbed on filter fan root got back in the feed chute 8, stop in the floatation clean coal product that this part material enters blowpit 9, thereby reduce floatation clean coal moisture.
Claims (2)
