Description

Technical Field

[0001] The utility model belongs to the technical field of filter presses, and particularly relates to a vertical continuous filter press. Background Art

[0002] In the prior art, when most filter presses filter sediment slurries, they pressurize and dehydrate by squeezing multiple filter plates. After the filtration is completed, it is necessary to unload the filter plates one by one. The pressurized dehydration process will cause a large amount of energy consumption problems; when most filter presses are in operation, the unloading operation is not continuous, resulting in low work efficiency; machine maintenance is inconvenient, the cost is too high, and the occupied space is large, resulting in insufficient space utilization. To solve the problems of high energy consumption, discontinuous operation, and high cost existing in the prior art filter presses, the utility model intends to propose a vertical continuous filter press with simple continuous operation. This device has an open-frame structure, which can reduce the manufacturing cost and maintenance cost of the machine. During the filtration operation, the filter cake can be dehydrated by its own gravity and the filtration module, with continuous work and reliable performance. Summary of the Utility Model

[0003] Aiming at the problems existing in the prior art, the filter press of the utility model is designed as a vertical filter press from the traditional plate-frame filter press. The slurry to be filtered enters through the feed box. The slurry in the feed box enters the filter cavity by gravity. The filter cavity is sealed by a sealing rubber belt. The slurry in the filter cavity loses a part of water by its own gravity. The removed water is collected in the water collection tank by a negative pressure aspirator and then discharged. The viscous slurry at the lower part of the filter cavity is pressed by a pressing roller to ensure that the solid content of the processed filter cake meets the specified requirements. The filter cake falls into the blanking box and then onto the conveyor belt for transfer.

[0013] Both the first sprocket support 16-17 and the second sprocket support 16-20 are provided with boss structures on the side close to the rubber belt. The boss structures are respectively in contact with the inner sides of the first drive chain 16-10 and the second sprocket 16-11, enabling the inner sides of the first drive chain 16-10 and the second sprocket 16-11 to slide on the boss structures. A pressure towards the rubber belt is exerted on the first drive chain 16-10 and the second sprocket 16-11 by the boss structures, further enhancing the edge sealing and pressure filtration effect.

A first negative pressure aspirator 16-3 and a second negative pressure aspirator 16-4 are respectively connected to the first water collecting tank 16-1 and the second water collecting tank 16-2. By means of the first negative pressure aspirator 16-3 and the second negative pressure aspirator 16-4, it is possible to prevent the filtered water from flowing back into the filter cake and affecting its solid content.

[0015] Drain pipes are respectively arranged behind the first water collecting tank 16-1 and the second water collecting tank 16-2 for discharging the filtered water in the first water collecting tank 16-1 and the second water collecting tank 16-2.

The height of the first feeding roller 19 and the second feeding roller 20 can be adjusted by the first hydraulic cylinder 21 and the second hydraulic cylinder 22, thereby adjusting the slurry feeding position to meet the pressure filtration work of materials with different particle sizes, and the tension of the first rubber belt 23 and the second rubber belt 24 can also be adjusted.

[0018] The diameters of the first feeding roller 19 and the second feeding roller 20 are the same as those of the first squeezing roller 9 and the second squeezing roller 11. The axis of the first feeding roller 19 is offset 50 mm to the left relative to the axis of the first squeezing roller 9, and the axis of the second feeding roller 20 is offset 50 mm to the right relative to the axis of the second squeezing roller 11, making the filter cavity of the vertical filter press in a "V" shape, which is convenient for the dehydration of the slurry.

[0019] A feeding box 27 is welded on the slide rail 18, and a filter cloth support A 28 and a filter cloth support B 29 are welded on the support platform 17. The filter cloth support A 28 and the filter cloth support B 29 are axially symmetric, and the filter cloth support A 28 and the filter cloth support B 29 can play a role in limiting the first filter cloth 25 and the second filter cloth 26.

[0027] 5. The slurry will be filter-pressed again by the first squeezing roller 9 and the second squeezing roller 11, which can improve the solid content rate of the filter cake. After the filter pressing is completed, the filter cake will fall into the blanking box 4, and then is conveyed to the next processing process by the conveyor belt 3.

[0028] 6. When the vertical filter press performs long-term filter pressing work, the first filter cloth 25 and the second filter cloth 26 will be offset and misaligned, which can be adjusted by the first alignment adjuster 30 and the second alignment adjuster 31.

[0029] 7.

Adjusting pointers in contact with the first filter cloth 25 and the second filter cloth 26 are respectively provided in the first deviation rectifier 30 and the second deviation rectifier 31. During long-term filter pressing operation, the tightness of the first filter cloth 25 and the second filter cloth 26 is likely to change. By adjusting the position of the adjusting pointer of the deviation rectifier, the tension of the filter cloth can be adjusted to prevent the filter cloth from shifting.

[0062] As Figure 1 and Figure 2 shown, a first water supply pipe 32 and a second water supply pipe 33 are respectively fixed on both sides of the front end of the main body frame 1. The upper ends of the first water supply pipe 32 and the second water supply pipe 33 are respectively connected to a first filter cloth cleaner 34 and a second filter cloth cleaner 35 through flanges. The first filter cloth cleaner 34 and the second filter cloth cleaner 35 include a water spraying structure facing the first filter cloth 25 and the second filter cloth 26. The first filter cloth 25 and the second filter cloth 26 can be cleaned by the first filter cloth cleaner 34 and the second filter cloth cleaner 35, improving the production efficiency.
