Description

Technical Field

[0001] The invention relates to a sludge unloading device, in particular to a sludge unloading device of a deep sludge filter pressing and dewatering system. Background Art

[0002] At present, the working principle of the plate and frame filter press is to squeeze the plate and frame to discharge the water in the sludge through the filter cloth to achieve the purpose of dehydration. It is mainly composed of a recessed filter plate, a frame, an automatic-pneumatic closing system, a side plate suspension system, a filter plate vibration system, an air compression device, and a filter cloth high-pressure washing device, and is bulky. In order to achieve the effect of filter pressing and dehydration, the plate and frame sludge filter press needs to add iron salt and lime as additives, which undoubtedly increases the cost of sludge filter pressing, and increases the sludge volume before dehydrating the sludge. Moreover, after the sludge is dehydrated and filtered, manual operation is required to handle the dirt on the filter cloth, which has high labor intensity and low work efficiency. Summary of the invention

[0003] The purpose of the present invention is to provide a sludge unloading device for a deep sludge filter pressing and dewatering system, so as to solve the problem that after sludge dewatering and filtration, the plate and frame filter press in the prior art needs manual operation to handle the sludge on the filter cloth, which results in high labor intensity and low work efficiency for the workers.

[0004] The object of the present invention is achieved in this way: the unloading and cleaning device comprises: a filter cloth drum, a gripper, a filter cloth drum seat, rollers, a roller car reducer, a reel reducer, a detachable coupling, a sweeper, a cleaning water pipe, a second funnel, a tensioning roller, a pressing roller, a redirecting roller, a reel motor, a unloading workbench, a first funnel, a roller car track, a roller car and a filter roller conveying device; the filter roller conveying device is connected to the unloading workbench; roller car tracks are connected to both sides of the unloading workbench, the roller car is located on the roller car tracks, and the roller car reducer, the cleaning water pipe, the tensioning roller and the pressing roller are connected to the roller car Roller; a corresponding redirecting roller is arranged at the lower part of the pressing roller, and the redirecting roller is fixed on the unloading workbench; a first funnel and a second funnel are respectively connected to the two ends of the unloading workbench, and a sweeper is respectively connected above the first funnel and the second funnel; a filter cloth drum seat is connected to the unloading workbench, the filter cloth drum seat is located between the roller car tracks, a filter cloth drum is installed on the filter cloth drum seat, the input shaft of the filter cloth drum is connected to the drum reducer through a detachable coupling, and the input shaft of the drum reducer is connected to the drum motor; the sweeper and the cleaning water pipe are located on the running track of the filter cloth, and rollers are also connected to the running track of the filter cloth.

[0005] The filter roller conveying device comprises: an electric hoist, a hoist track, a hoist frame, a lifting beam and a grabber; the hoist frame is connected to the unloading workbench; there is a hoist track on the hoist frame, an electric hoist is installed on the hoist track, and the lower end of the electric hoist is connected to the grabber through the lifting beam.

[0006] The sweeper is a scraper blade, including a front scraper blade and a rear scraper blade, which have the same structure.

[0007] The grab and release device includes: a grab and release cylinder, a gear shaft, a gear wheel body, a cylinder joint, a grab and release bracket and a lifting plate; the grab and release cylinder is connected to the upper end of the lifting plate, the grab and release bracket is connected to the lower end of the lifting plate, the grab and release cylinder passes through the lifting plate, is connected to the gear shaft through the cylinder joint, a gear wheel body is connected to each side of the gear shaft, and the gear wheel body is meshed with the gear shaft; the gear wheel body and the gear shaft are both connected to the grab and release bracket, the gear wheel body is hinged to the grab and release bracket through a pin shaft, and a hook is provided at the end of the gear wheel body.

[0008] Beneficial effect: Due to the adoption of the above scheme, the sludge unloading device uses the filter roller conveying device to lift the filter cloth drum on the upper end of the filter press barrel to the unloading workbench, the drum reducer drives the filter cloth drum to rotate, and the sweeper and the cleaning water pipe clean the sludge on the filter cloth drum, which effectively improves the unloading and cleaning efficiency of the filter cloth, reduces the equipment footprint and reduces a lot of labor. Thus, an efficient and energy-saving filter cloth unloading and cleaning effect is achieved.

[0009] When working, the roller car moves to the filter cloth drum and waits for orders;

[0010] The grabber will drag the filter cloth drum connected to the filter cloth fixed on one side of the filter cloth drum from above the roller carrier to the discharging station platform. After it is in place, it will be embedded in the transmission fixed shaft to play the role of fixing and driving rotation. At this time, the roller carrier is between the filter press and the filter cloth drum, and lifts the filter cloth.

[0011] The roller carrier moves horizontally toward the direction of the filter cloth drum and passes over the filter cloth drum to reach the designated position and fix it; after reaching the fixed position, the roller carrier forms a fixed angle with the tensioning roller above to fix and tension the filter cloth carrying the sludge;

[0012] The reel reducer embedded in the filter cloth drum starts, driving the filter cloth drum to rotate, and slowly rolls the filter cloth onto the filter cloth drum. At the same time, the upper and lower cleaners of the filter cloth are in place to peel off the sludge after pressure filtration on the filter cloth. The sludge peeled off from the upper filter cloth falls into the second funnel on one side of the roller car, and the sludge peeled off from the lower filter cloth falls into the first funnel on the original side of the filter cloth drum.

[0013] While the filter cloth drum rotates and pulls the filter cloth, the high-pressure plastic water pipe between the filter cloth drum and the roller car starts to work. There is a cleaning water pipe on the upper and lower sides of the filter cloth, which performs high-pressure flushing on the filter cloth treated by the scraper to clean the filter cloth; after the filter cloth drum has completed gathering the filter cloth, the cleaning water pipe stops working.

[0014] The sludge unloading device of the present invention occupies a small area, realizes mechanized and automatic removal of sludge from the filter cloth, and simultaneously sprays water to clean the filter cloth, thereby greatly improving work efficiency and reducing the labor intensity of workers.

[0015] The invention solves the problem that after the sludge is dehydrated and filtered, manual operation is required to process the sludge on the filter cloth, which results in high labor intensity and low work efficiency for the workers, thus achieving the purpose of the invention.

[0016] Advantages: 1. The equipment has a compact structure and effectively saves equipment floor space.

[0017] 2. The equipment runs stably and reliably, and has a high degree of automation, so no operator is required on site.

[0018] 3. This equipment can realize the efficient separation of dry sludge and filter cloth after squeezing and clean the filter cloth at the same time.

[0019] 4. This equipment can completely clean the dry sludge on the filter cloth with high working efficiency. BRIEF DESCRIPTION OF THE DRAWINGS
