Description

Technical Field

[0001] This utility model belongs to the technical field of filter press unloading devices, and in particular relates to an unloading device for a filter press. Background Technology

[0002] A plate and frame filter press consists of alternating plates and frames. Filter cloth is covered on both sides of the filter plates, and a pressing device presses the plates and frames together, forming a filter chamber. Small holes are drilled at the same location at the top center of the plates and frames, forming a channel after pressing. Sludge pressurized to 0.2-0.4 MPa enters the filter chamber through this channel. Grooves are engraved on the surface of the filter plates, and channels are drilled at the bottom for filtrate discharge. Under pressure, the filtrate passes through the filter cloth and flows out of the filter press along the grooves and channels, thus dewatering the sludge.

[0003] In wastewater treatment plants, the treated sludge has a high water content and large volume, making it inconvenient to transport and dispose of. Plate and frame filter presses can dewater the sludge, reducing its water content and volume, thus facilitating subsequent sludge disposal methods such as landfill and incineration.

[0004] When using existing equipment, after unloading the impurities from the filter press plates, some impurities will remain on the filter press plates. If they are not cleaned and removed, it may affect the subsequent reuse of the filter press plates and result in low unloading efficiency. Therefore, we propose an unloading device for filter presses. Utility Model Content

A corrugated pipe is fixedly connected to the bottom output end of the water pump. The outer wall of the corrugated pipe is inserted into the inner wall of the water storage tank. A water storage tank 2 is fixedly connected to the outer wall of the corrugated pipe away from the water pump. Several water spray plates are fixedly connected to the bottom outer wall of the water storage tank 2. Several slide rails 2 are fixedly connected to the outer wall of the filter press body near the slide rail.

[0016] This utility model has the following beneficial effects:

[0017] 1. This utility model incorporates a brush plate on the main body of the filter press. When the equipment is needed, the water pump is activated, which delivers clean water from the spring through a corrugated pipe to the water storage tank. The water is then evenly sprayed onto both sides of the filter press plates via a sprinkler plate for cleaning. The electric telescopic rod can adjust the overall height of the support rod, preventing the sprinkler plate from jamming the filter press plates. The filter plates filter the clean water in the water storage tank, preventing it from being contaminated by a large amount of silt and other impurities. This allows for timely cleaning of the filter press plates after unloading, preventing impurities from remaining on the plates and affecting the next use of the device. Simultaneously, the device can transport the unloaded impurities, preventing them from accumulating at the bottom of the device. Furthermore, the device can clean the conveyor belt, preventing impurities from accumulating on it and affecting the conveying efficiency.

[0018] 2. This utility model incorporates a belt on a pulley. During operation, rotating the threaded rod on the left side causes the slider on the left side to slide within the second slide rail, which in turn moves the electric telescopic rod on the left side. This movement of the electric telescopic rod on the left side moves the support rod, which in turn moves the electric telescopic rod on the right side. The movement of the electric telescopic rod on the right side moves the slider on the right side within the second slide rail, thus adjusting the support rod directly above the different filter plates. This allows the filter plates to be extended one by one in sequence, improving the efficiency and accuracy of stretching during filter plate unloading. Simultaneously, it allows for repeated tapping of individual filter plates, shaking off impurities and further improving unloading efficiency and accuracy.

[0019] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0031] Please see Figure 1-7 As shown, this utility model is a discharge device for a filter press, including a filter press body 1, a motor frame 101 fixedly connected to the outer wall of the filter press body 1, a plurality of slide rails 102 fixedly connected to the outer wall of the filter press body 1, a cleaning mechanism 2 provided on the outer wall of the filter press body 1, the slide rails 102 can limit the position of the limiting block 106, so that it can only slide within the slide rail 102, thereby controlling the position of the filter plate 103;

[0032] The cleaning mechanism 2 includes a first motor 201, the outer wall of which is fixedly connected to the outer wall of the motor frame 101. Several drive shafts 202 are rotatably connected to the inner wall of the filter press body 1 near the first motor 201. The drive shafts 202 can drive the conveyor belt 203. When the first motor 201 is started, its rotation drives the left drive shaft 202 to rotate, which in turn causes the conveyor belt 203 to rotate. The rotation of the conveyor belt 203 drives the right drive shaft 202 to rotate. The left drive shaft 202... The outer wall of the filter press 202 is fixedly connected to the bottom output end of the first motor 201. A conveyor belt 203 is driven to the outer wall of the drive shaft 202. A brush plate 204 is fixedly connected to the outer wall of the filter press body 1 near the conveyor belt 203. The brush plate 204 can clean the conveyor belt 203, keeping it clean and facilitating repeated use of the device. A filter plate 205 is slidably connected to the inner wall of the water tank 104. Several positioning holes 206 are opened on the inner wall of the filter plate 205. The water tank 104 is located near the positioning holes 206. Several limiting rods 207 are fixedly connected to the outer wall of one end of the filter press. The position of the limiting rods 209 can be limited by the position of the insertion rods 209, so that the filter press can only slide on the limiting rods 207. The outer walls of the limiting rods 207 are slidably connected to the insertion rods 209. Several limiting blocks 106 are slidably connected to the inner wall of the slide rail 102. The inner walls of the limiting blocks 106 are slidably connected to the filter press plates 103. A water storage tank 104 is fixedly connected to the outer wall of the filter press body 1 at the end away from the motor frame 101. The water storage tank 104 can be used to clean water. For temporary storage, and to prevent temporary water shortage during subsequent cleaning, several limit blocks 106 are fixedly connected to the inner walls of springs 105. The outer walls of springs 105 are fixedly connected to the outer walls of filter press plates 103. Several limit blocks 2 107 are fixedly connected to the outer walls of filter press plates 103 on the right side. The outer walls of several limit blocks 2 107 are slidably connected to the inner walls of slide rails 102. Limit blocks 2 107 can adjust the position of the rightmost limit block 106, thereby controlling the position of the rightmost filter press plate 103.

[0033] The outer wall of the insertion rod 209 is inserted into the inner wall of the positioning hole 206. Several insertion rods 209 are fixedly connected to the outer walls of springs 208. The outer wall of springs 208 is fixedly connected to the outer wall of the limiting rod 207. Springs 208, through their own elastic force, will always press against the insertion rod 209, thus ensuring that the insertion rod 209 remains inserted in the positioning hole 206 and preventing it from slipping out. A water pump 215 is fixedly connected to the outer wall of the filter press body 1 near the water storage tank 104. A waveguide is fixedly connected to the bottom output end of the water pump 215. The corrugated pipe 210 is inserted into the inner wall of the water storage tank 104. Because of its relatively flexible material, the corrugated pipe 210 can continuously stretch or contract when the water storage tank 211 moves, thus preventing interruption of water flow. The outer wall of the end of the corrugated pipe 210 away from the water pump 215 is fixedly connected to the water storage tank 211. Several water spray plates 212 are fixedly connected to the bottom outer wall of the water storage tank 211. Several water spray plates 212 are fixedly connected to the outer wall of the filter press body 1 near the slide rail 102. A second slide rail 216 restricts the movement trajectory of the slider 306, allowing it to slide only within the slider 306. A threaded rod 213 is threadedly connected to the inner wall of the left slide rail 216, and a limiting slide rod 214 is fixedly connected to the inner wall of the right slide rail 216. A feeding mechanism 3 is provided on the outer wall of the filter press body 1. The feeding mechanism 3 includes several threaded rods 301. When the threaded rods 301 rotate, they cause the limiting block 107 to slide within the slide rail 102. This allows control over the position of the limiting block 106. The inner wall of the threaded rod 301 is threadedly connected to the inner wall of the limiting block 107. Several threaded rods 301 are fixedly connected to pulleys 302 on the outer wall of their ends near the first motor 201. The outer wall of the pulleys 302 is connected to a belt 303, which can drive the belt 303. When the outer threaded rod 301 is rotated, the rotation of the threaded rod 301 can drive the pulley 302 to rotate, which in turn can drive the belt 303 to rotate.

[0034] Several steel wire ropes 304 are fixedly connected to the outer wall of one end of each filter press plate 103 near the limiting block 107. The outer wall of the steel wire ropes 304 is fixedly connected to the outer wall of the filter press body 1. Several sliders 306 are slidably connected to the inner wall of each slide rail 216. The sliders 306 can adjust the position of the electric telescopic rod 307. By rotating the threaded rod 213, the sliders 306 can slide within the slide rail 216, thereby driving the electric telescopic rod 307 to move. The tops of the sliders 306... Electric telescopic rods 307 are fixedly connected to the outer walls of the tank. A support rod 308 is fixedly connected to the top output end of each electric telescopic rod 307. The outer wall of the support rod 308 is fixedly connected to the bottom outer wall of the water storage tank 211. The support rod 308 provides support for the water storage tank 211 and can also move when it moves. Several electric telescopic rods 309 are fixedly connected to the bottom outer wall of the support rod 308. A connecting rod is fixedly connected to the bottom output end of each electric telescopic rod 309. The connecting frame 310 has a convex shaft 311 rotatably connected to its inner wall. When the convex shaft 311 rotates, it continuously strikes the top of the filter press plate 103, causing it to vibrate and thus shaking off the impurities filtered out of the filter press plate 103. A gear 312 is fixedly connected to the outer wall of the convex shaft 311. A second motor frame 313 is fixedly connected to the top outer wall of the connecting frame 310. A second motor 314 is fixedly connected to the inner wall of the second motor frame 313. The second motor frame 313 can limit the position of the second motor 314. To prevent the second motor 314 from shaking during normal operation and affecting subsequent normal transmission, a transmission shaft 315 is fixedly connected to the bottom output end of the second motor 314. A crown gear 305 is fixedly connected to the outer wall of the end of the transmission shaft 315 near the cam shaft 311. The outer wall of the crown gear 305 meshes with the outer wall of the gear 312. Since the crown gear 305 and the gear 312 mesh with each other, when the crown gear 305 rotates, it can drive the gear 312 to rotate, thereby causing the cam shaft 311 to rotate.

[0035] One specific application of this embodiment is:

[0036] When the equipment is needed, the first motor 201 is started. The rotation of the first motor 201 drives the left drive shaft 202 to rotate, causing the conveyor belt 203 to rotate, which in turn drives the right drive shaft 202 to rotate. The brush plate 204 can scrape off the impurities remaining on the conveyor belt 203. First, the outer threaded rod 301 is rotated, and the connecting frame 310 rotates, which drives the pulley 302 to rotate, causing the belt 303 to rotate. The rotation of the belt 303 drives the inner threaded rod 301 to rotate. When the threaded rod 301 rotates, it can drive the limit block 107 to move away from the pulley 302. The movement of the limit block 107 can drive the limit block 106 to slide in the slide rail 102, which in turn drives the rightmost filter plate 103 to move towards the rightmost side. Moving away from the pulley 302, the multiple limit blocks 106 are connected by wire ropes 304, with the other end of the wire ropes 304 fixed to the filter press body 1. Therefore, when the rightmost filter plate 103 moves, it will drive multiple filter plates 103 to move simultaneously away from the pulley 302. The spacing between the filter plates 103 is consistent. Then, rotating the left threaded rod 213 causes the left slider 306 to slide within the slide rail 216, thereby driving the left electric telescopic rod 307 to move. The movement of the left electric telescopic rod 307 drives the support rod 308, which in turn drives the right electric telescopic rod 307. The movement of the right electric telescopic rod 307 drives the right slider 306. 6. Slide within slide rail 216 to adjust support rod 308 directly above different filter plates 103. Adjust connecting frame 310 to a suitable height via electric telescopic rod 309. Start second motor 314. Rotation of second motor 314 drives transmission shaft 315 to rotate, causing crown gear 305 to rotate. Rotation of crown gear 305 drives cam shaft 311 to rotate within connecting frame 310, continuously striking the top of filter plate 103 to shake it. This shakes off the impurities filtered from filter plate 103, completing unloading. The fallen impurities are transported away by conveyor belt 203. Spring 105 provides cushioning for filter plate 103, preventing damage during shaking, and simultaneously allowing filter plate 103 to move quickly. After rapid reset and unloading, the water pump 215 is started. The water pump 215 can transport the clean water in the spring 105 to the water storage tank 211 through the corrugated pipe 210, and then spray it evenly on both sides of the filter press plate 103 via the sprinkler plate 212 to clean it. The electric telescopic rod 307 can adjust the overall height of the support rod 308, thereby preventing the sprinkler plate 212 from jamming the filter press plate 103. The filter plate 205 can filter the clean water in the water storage tank 104 to prevent it from containing a large amount of silt and other impurities that could contaminate the filter press plate 103. When the filter plate 205 is clogged and needs to be replaced, pull up the multiple insert rods 209 to completely disengage them from the positioning hole 206. Then, rotate the insert rods 209 at a certain angle to remove the filter plate 205.Spring 208 ensures that the insertion rod 209 is always inserted into the positioning hole 206 when normally fixed, preventing the filter plate 205 from falling off on its own.
