Description

Technical Field

[0001] This utility model relates to the field of coal slime processing technology, specifically to a coal slime filter press unloading device. Background Technology

[0002] The unloading device of a coal slime filter press is the core component of the dewatering system, responsible for efficiently discharging the filtrate separated during the coal slime dewatering process. Its core function is to collect the liquid that has penetrated the filter membrane in a directional manner through a flow guiding structure (such as a water guide trough, a liquid collection pipe, or a drainage channel), and then quickly extract it from the filter chamber with the help of a matching drainage pump (such as a centrifugal pump or a vacuum pump).

[0003] After the filter membrane is demolded, the coal slime falls off, but some residual coal slime residue will remain on the filter membrane. If the staff does not clean it, it will affect the next dewatering, or more precisely, the normal operation of the unloading device itself. Therefore, the staff needs to hold a shovel next to the equipment to clean the filter membrane after demolding. However, if the staff gets too close to the equipment, there is a safety hazard. Utility Model Content

[0004] The purpose of this utility model is to provide a coal slime filter press unloading device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a coal slime filter press unloading device, comprising a filter press body, a filter membrane body, a frame, and a pump body, and further comprising:

[0006] The frame is bolted to the top of the support column, and there are two sets of support columns. The two sides of the support columns are bolted to the toothed track. A movable plate is provided above the filter press body. Vertical plates are bolted to both sides of the top of the movable plate. A transmission column is rotatably connected to the surface of the vertical plate. Transmission gears are bolted to both ends of the transmission column, and the transmission gears mesh with the toothed track. A drive motor that drives the transmission column to rotate is also bolted to the top of the movable plate.

[0007] A multi-stage hydraulic rod is bolted to the bottom of the movable plate. The output shaft of the multi-stage hydraulic rod is bolted to a lifting plate. Several linear reciprocating motors are bolted to the bottom of the lifting plate. The output shaft of the linear reciprocating motor is fixed with a threaded column. An impact block is provided on one side of the linear reciprocating motor. A threaded groove is opened on one side of the impact block, and the threaded groove is threadedly connected to the surface of the threaded column. Sliding components are provided on both sides of the movable plate.

[0008] Preferably, the sliding assembly includes a connecting rod, a sliding sleeve, and a movable column. One end of the connecting rod is bolted to the bottom of the movable plate, and the other end of the connecting rod is welded to the sliding sleeve. The movable column is bolted to the support column, and the sliding sleeve is slidably connected to the surface of the movable column.

[0009] Preferably, a trigger rod is welded to the bottom of the sliding sleeve, and a limit switch is bolted to the surface of the support column.

[0010] Preferably, the length of the toothed track is the same as the length of the movable column.

[0012] Preferably, the output shaft of the drive motor is connected to the transmission column via gear transmission.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] This invention uses a drive motor to rotate the transmission column and transmission gears, which, in conjunction with the toothed track, move the moving plate and lifting plate horizontally. A multi-stage hydraulic rod is activated to lower the lifting plate and linear reciprocating motor, causing the output shaft of the linear reciprocating motor to repeatedly strike the filter membrane with an impact block. This causes the filter membrane to vibrate significantly, dislodging residue and replacing manual cleaning operations. This allows workers to operate away from the equipment, making it safer.

[0021] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0022] Please see Figures 1-5 As shown, a coal slime filter press unloading device includes a filter press body 1, a filter membrane body 2, a frame 3, and a pump body 11. The filter press body 1 achieves dewatering through the synergistic action of the filter membrane body 2 and the pump body 11. First, a high-pressure pump injects coal slime into the filter chamber of the filter press. Under the pressure of the filter plates, water penetrates the filter membrane (usually a polymer material or woven fiber with pores that only allow liquid to pass through) while solid particles are trapped on the surface of the filter membrane to form a filter cake. Subsequently, during the pressure holding stage, mechanical pressure is continuously applied to further compress the pores of the filter cake and discharge the internal water. At the same time, a matching vacuum pump or centrifugal pump extracts the liquid that has seeped out from the other side of the filter membrane and discharges it. Water is discharged centrally through pipelines. The entire dewatering process, through the combined action of pressure difference and pump body 11, reduces the moisture content of coal slime from the initial 60%-80% to 15%-25%, achieving efficient solid-liquid separation. The above is existing technology, and its specific structure is not shown in the figure. The top of the frame 3 is bolted with a support column 4, and there are two sets of support columns 4. Toothed rails 5 are bolted between the support columns 4 on both sides. A movable plate 6 is set above the filter press body 1. Vertical plates 7 are bolted to both sides of the top of the movable plate 6. A transmission column 8 is rotatably connected to the surface of the vertical plate 7. Transmission gears 9 are bolted to both ends of the transmission column 8, and the transmission gears 9 mesh with the toothed rails 5. The top of the movable plate 6 is also bolted with a drive motor 10 that drives the transmission column 8 to rotate. The output shaft of the drive motor 10 is connected to the transmission column 8 through gear transmission. The drive motor 10 is used to drive the transmission column 8 to rotate. The drive motor 10 is connected to a PLC outside the production equipment, which is existing technology. The bottom of the movable plate 6 is bolted with a multi-stage hydraulic rod 12. The output shaft of the multi-stage hydraulic rod 12 is bolted with a lifting plate 13. The bottom of the lifting plate 13 is bolted with several linear reciprocating motors 14. The output shaft of the linear reciprocating motor 14 is fixed with a threaded column 15. An impact block 17 is provided on one side of the linear reciprocating motor 14. The impact block 17 is spherically designed. Furthermore, the impact block 17 is made of plastic to prevent damage caused by frequent impacts between the impact block 17 and the filter membrane body 2. A threaded groove 16 is provided on one side of the impact block 17, and the threaded groove 16 is threadedly connected to the surface of the threaded post 15. Pick up the impact block 17 and align its threaded groove 16 with the threaded post 15. Then rotate the impact block 17 so that the threaded groove 16 rotates and fits onto the surface of the threaded post 15 and fixes it to the impact block 17, thereby fixing the impact block 17 to the output shaft of the linear reciprocating motor 14. If the impact block 17 is rotated in the opposite direction, the impact block 17 can be removed for replacement. Sliding components 18 are provided on both sides of the moving plate 6.

[0023] The sliding assembly 18 includes a connecting rod 181, a sliding sleeve 182, and a movable column 183. One end of the connecting rod 181 is bolted to the bottom of the moving plate 6, and the other end of the connecting rod 181 is welded to the sliding sleeve 182. The movable column 183 is bolted to the support column 4, and the sliding sleeve 182 is slidably connected to the surface of the movable column 183. During the movement of the moving plate 6, the sliding sleeve 182 can be driven by the connecting rod 181 to slide along the surface of the movable column 183, thereby increasing the movement stability of the moving plate 6. The length of the toothed track 5 is the same as the length of the movable column 183.

[0024] After the filter press operation is completed, the pressure plate of the filter press drives the filter membrane body 2 to open the mold. Then, the drive motor 10 is turned on to drive the transmission column 8 and the transmission gear 9 to rotate. The transmission gear 9 moves along the surface of the toothed track 5 and drives the moving plate 6 to move. The moving plate 6 drives the multi-stage hydraulic rod 12 and the lifting plate 13 below to move together until the lifting plate 13 moves to the front of the filter membrane body 2 after the mold is opened. Then, the drive motor 10 is stopped and the multi-stage hydraulic rod 12 is turned on. Its output shaft extends to drive the lifting plate 13 and the linear reciprocating motor 14 to descend. Then, the impact block 17 on the output shaft of the linear reciprocating motor 14 is aligned with the filter membrane body 2. The linear reciprocating motor 14 is turned on, and its output shaft moves back and forth, driving the impact block 17 to strike the filter membrane body 2, causing the coal sludge residue on the surface of the filter membrane body 2 to fall off. This replaces the operation of the workers to clean the residue on the filter membrane body 2 with a shovel. It allows the workers to control the device from a distance, which is safer.

[0025] After one filter membrane body 2 is cleaned, the multi-stage hydraulic rod 12 is activated to drive the lifting plate 13 to rise. Then, the next filter membrane body 2 is opened, and the drive motor 10 is turned on to move the lifting plate 13 to the front and above the next filter membrane body 2 for cleaning.

[0026] A trigger rod 184 is welded to the bottom of the sliding sleeve 182, and a limit switch 185 is bolted to the surface of the support column 4. During the movement of the sliding sleeve 182 following the moving plate 6, the trigger rod 184 can contact the limit switch 185 before approaching the support column 4. The limit switch 185 is connected to the PLC controller of the processing site, and then the drive motor 10 is turned off, thereby limiting the movement range of the moving plate 6.

[0027] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
