The inclined screen dry-wet separator separates solids and liquids through vibration screening and extrusion separation. However, when using inclined plates for screening, if the solid-liquid mixture contains a large number of solid particles of varying sizes, they are prone to accumulating on the inclined plates, causing blockage and affecting the filtration effect. Therefore, an inclined screen dry-wet separator is needed to meet people's needs. Utility Model Content

This utility model, through the setting of a linkage motor, scraper and other structures, can turn on the linkage motor during the screening process to make the scraper scrape back and forth on the inclined screen plate, further preventing particles from adhering and accumulating on the inclined screen plate. In addition, the process will drive the two spray pipes to move back and forth, so that the nozzles can evenly spray water on the inclined screen plate for flushing, further improving the anti-clogging effect.

[0027] To better understand the purpose, structure, and function of this utility model, the following description, in conjunction with the accompanying drawings, provides a more detailed account of an inclined screen type dry-wet separator.
[0028] like Figures 1 to 8As shown, a slanted screen type dry-wet separator includes a separator housing 100, a liquid storage tank 101 fixedly installed on the separator housing 100, a liquid outlet 102 on the liquid storage tank 101, a liquid delivery pipe 103 fixedly installed on one side of the liquid storage tank 101, the liquid delivery pipe 103 communicating with the liquid storage tank 101, a movably mounted slanted screen plate 104 on the separator housing 100, a connecting frame 105 fixedly installed on the slanted screen plate 104, a vibration motor 106 fixedly installed on the connecting frame 105, a recovery box 107 fixedly installed on the separator housing 100, the recovery box 107 located on the bottom side of the slanted screen plate 104, a liquid outlet pipe 108 fixedly installed on the recovery box 107, the liquid outlet pipe 108 communicating with the recovery box 107, and a liquid outlet pipe 108 fixedly installed on one side of the separator housing 100. A conveyor motor 109 is fixedly installed, and a connecting shaft 110 is fixedly installed at the output end of the conveyor motor 109. The connecting shaft 110 is rotatably mounted on the separator housing 100, and a spiral blade 111 is fixedly installed on the connecting shaft 110. An arc-shaped screen plate 112 is fixedly installed on the inner wall of the recovery box 107, and the arc-shaped screen plate 112 is in contact with the spiral blade 111. A slag discharge box 113 is fixedly installed on one side of the separator housing 100, and a compression filter screen 114 is fixedly installed on the inner wall of the slag discharge box 113. The spiral blade 111 is movably installed inside the compression filter screen 114. A flow guide frame 115 is fixedly installed on the slag discharge box 113, and the flow guide frame 115 is fixedly installed on the separator housing 100. The flow guide frame 115 is connected to the recovery box 107. A cover plate 200 is fixedly installed on the inclined screen plate 104. Two telescopic corrugated pipes 201 are fixedly installed on the inner walls of both sides of the cover plate 200. The same spray pipe 202 is fixedly installed on the two telescopic corrugated pipes 201 on the same side. Multiple nozzles 203 are opened on the two spray pipes 202, and the nozzles 203 correspond to the inclined screen plate 104. The same U-shaped pipe 204 is fixedly installed on the corresponding two telescopic corrugated pipes 201. A conveying pipe 205 is fixedly installed on the U-shaped pipe 204. The telescopic corrugated pipes 201 are connected to the spray pipes 202, and the corresponding telescopic corrugated pipes 201 are connected to the U-shaped pipes 204. The U-shaped pipes 204 are connected to the conveying pipes 205. The water pump is connected to the delivery pipe 103 through a pipeline to the sedimentation tank. The solid-liquid mixture is extracted and transported to the storage tank 101. When the storage tank 101 is full, it overflows from the outlet 102. The overflowing solid-liquid mixture flows onto the inclined screen plate 104. At the same time, the vibration motor 106 and the conveying motor 109 can be turned on. Under the action of the vibration motor 106, the inclined screen plate 104 vibrates to screen the solid-liquid mixture, promoting the downward sliding of solid particles on the inclined screen plate 104. The liquid flows through the inclined screen plate 104 into the recovery tank 107. The screened solid particles slowly fall along the inclined screen plate 104 onto the arc-shaped screen plate 112. During this process, the spiral blade 111 pushes the solid particles on the arc-shaped screen plate 112 to move. The water in the particles falls through the arc-shaped screen plate 112 into the recovery tank 107.Finally, the solid particles are pushed to the squeeze filter 114 for squeezing and drainage, falling out of the slag discharge box 113. The liquid filtered from the squeeze filter 114 flows into the recovery box 107 through the guide frame 115. The liquid in the recovery box 107 can be discharged through the liquid outlet pipe 108. During the screening process, a water pump can be connected to the conveying pipe 205 to pump water, which is then sprayed onto the inclined screen plate 104 through multiple nozzles 203 on the spray pipe 202. This washes the inclined screen plate 104, preventing the mesh of the inclined screen plate 104 from clogging, and simultaneously promoting the movement of particles on the inclined screen plate 104.
[0029] A linkage motor 300 is fixedly installed on one side of the cover plate 200. A positive and negative threaded rod 301 is fixedly installed at the output end of the linkage motor 300. The positive and negative threaded rod 301 is rotatably mounted on the cover plate 200. A linkage slide rod 302 is threaded onto the positive and negative threaded rod 301. The linkage slide rod 302 is slidably mounted on the inner wall of the cover plate 200. Two connecting rods 303 are fixedly installed on one side of the linkage slide rod 302. A common scraper is fixedly installed on one side of the two connecting rods 303. 304, the scraper 304 contacts the inclined screen plate 104, the connecting frame 105 and the vibration motor 106 are located between the two connecting rods 303, the linkage slide rod 302 has a threaded hole 305, the threaded rod 301 is threaded into the threaded hole 305, the linkage slide rod 302 has two horizontal slide grooves 306, and a horizontal guide rod 307 is slidably installed in each of the two horizontal slide grooves 306. Both horizontal guide rods 307 are fixedly installed on the cover plate 20. On the inner wall of 0, a rotating hole 308 is provided on the cover plate 200. The positive and negative threaded rods 301 are rotatably installed in the rotating hole 308. When the linkage motor 300 is turned on, its output end drives the positive and negative threaded rods 301 to rotate. The rotating positive and negative threaded rods 301 will rotate within the two rotating holes 308, thereby preventing the positive and negative threaded rods 301 from deviating during rotation. The continuously rotating positive and negative threaded rods 301 will drive the linkage slide rod 302 to reciprocate through the cooperation with the positive and negative threaded screw holes 305. The sliding linkage rod 302 slides on the two horizontal guide rods 307 through the two horizontal sliding grooves 306, thereby restricting the movement direction of the linkage rod 302. The continuously moving linkage rod 302 will drive the two connecting rods 303 to move, so that the connecting rods 303 drive the scraper 304 to move. Thus, under the drive of the linkage rod 302, the scraper 304 can scrape back and forth on the inclined screen plate 104 to prevent adhesion and accumulation on the inclined screen plate 104.
[0030] Two connecting seats 400 are fixedly installed on each of the two spray pipes 202. A common mounting frame 401 is fixedly installed on all four connecting seats 400. The mounting frame 401 is slidably installed on the inner wall of the cover plate 200. A first extrusion shaft 402 and a second extrusion shaft 403 are fixedly installed on one side of the linkage slide rod 302. A first corrugated plate 404 and a second corrugated plate 405 are fixedly installed on one side of the mounting frame 401. The first extrusion shaft 402 contacts the first corrugated plate 404, and the second extrusion shaft 403 contacts the second corrugated plate 405. Guide strips 406 are fixedly installed on the inner walls of both sides of the cover plate 200. Guide grooves 407 are provided on both guide strips 406. The two ends of the mounting frame 401 are slidably installed on the two guide grooves 407 respectively. Inside the groove 407, the reciprocating linkage slide bar 302 drives the first extrusion shaft 402 and the second extrusion shaft 403 to move. During the movement, the first extrusion shaft 402 and the second extrusion shaft 403 will alternately extrude the first wave plate 404 and the second wave plate 405, thereby causing the first wave plate 404 and the second wave plate 405 to drive the mounting frame 401 to slide back and forth. The reciprocating mounting frame 401 will slide in the guide grooves 407 on the two guide bars 406, thereby restricting the movement direction of the mounting frame 401. The reciprocating mounting frame 401 will drive the two spray pipes 202 to move back and forth through the connecting seat 400, thereby enabling the nozzles 203 to spray water evenly on the inclined screen plate 104, further improving the anti-clogging effect.
[0031] Working principle of this utility model:
[0032] In operation, a water pump is connected to the infusion pipe 103 via a pipeline to extract the solid-liquid mixture from the sedimentation tank and transport it to the storage tank 101 through the infusion pipe 103. When the storage tank 101 is full, the solid-liquid mixture overflows from the outlet 102 and flows onto the inclined screen plate 104. Simultaneously, the vibration motor 106 and the conveying motor 109 can be turned on. Under the action of the vibration motor 106, the connecting frame 105 and the inclined screen plate 104 vibrate, screening the solid-liquid mixture on the inclined screen plate 104 and promoting the downward sliding of solid particles on the inclined screen plate 104. The liquid flows through the inclined screen plate 104 into the recovery tank 107. The screened solid particles slowly fall onto the arc-shaped screen plate 112 along the inclined screen plate 104. During this process, the output end of the conveying motor 109 drives the connecting shaft 110 to rotate. The rotating connecting shaft 110 drives the spiral blade 111 to perform circular motion. Leaf 111 will push the solid particles on the arc-shaped screen plate 112 to move. During the movement, the water in the particles will fall into the recovery box 107 through the arc-shaped screen plate 112. Finally, the solid particles will be pushed to the squeeze filter screen 114 for squeezing and drainage, and fall out from the slag box 113. The liquid filtered from the squeeze filter screen 114 will flow into the recovery box 107 through the guide frame 115. The liquid in the recovery box 107 can be discharged through the liquid outlet pipe 108. During the screening process, the conveying pipe 205 can be connected to a water pump to pump water, so that the water is conveyed through the conveying pipe 205 and the U-shaped pipe 204 to the two telescopic corrugated pipes 201, and then conveyed through the two telescopic corrugated pipes 201 to the two spray pipes 202. Finally, the water is sprayed onto the inclined screen plate 104 through multiple nozzles 203 on the spray pipe 202 to flush the inclined screen plate 104, prevent the mesh of the inclined screen plate 104 from being blocked, and promote the movement of particles on the inclined screen plate 104.
[0033] By activating the linkage motor 300, its output end drives the positive and negative threaded rod 301 to rotate. The rotating positive and negative threaded rod 301 rotates within the two rotating holes 308, thus preventing the positive and negative threaded rod 301 from deviating during rotation. The continuously rotating positive and negative threaded rod 301 drives the linkage slide rod 302 to slide back and forth through the cooperation with the positive and negative threaded screw hole 305. The sliding linkage slide rod 302 slides on the two horizontal guide rods 307 through the two horizontal sliding grooves 306, thus restricting the movement direction of the linkage slide rod 302. The continuously moving linkage slide rod 302 drives the two connecting rods 303 to move, causing the connecting rods 303 to drive the scraper rod 304 to move. Thus, driven by the linkage slide rod 302, the scraper rod 304 can scrape back and forth on the inclined screen plate 104. To prevent adhesion and accumulation on the inclined screen plate 104, the reciprocating linkage slide rod 302 drives the first extrusion shaft 402 and the second extrusion shaft 403 to move. During the movement, the first extrusion shaft 402 and the second extrusion shaft 403 will alternately extrude the first wave plate 404 and the second wave plate 405, thereby causing the first wave plate 404 and the second wave plate 405 to drive the mounting frame 401 to slide back and forth. The reciprocating mounting frame 401 will slide in the guide grooves 407 on the two guide bars 406, thereby restricting the movement direction of the mounting frame 401. The reciprocating mounting frame 401 will drive the two spray pipes 202 to move back and forth through the connecting seat 400, thereby enabling the nozzles 203 to spray water evenly on the inclined screen plate 104, further improving the anti-clogging effect.
