Description

Technical Field

[0001] The present invention relates to the technical field of solid-liquid separation, and specifically to a rolling type high-efficiency solid-liquid separation device for silt. Background Art

[0002] Silt is a soft soil with a natural water content greater than the liquidity limit and a void ratio greater than 1.5. It is a modern sediment formed under the condition of microbial participation in an environment with slow water flow in bays, lakes or river bays. It is rich in organic matter, often grayish-black in color, with low mechanical strength and strong compressibility. If there is silt in the foundation, it is easy to cause the settlement of buildings. Currently, before treating silt, it is necessary to first conduct preliminary solid-liquid separation on it. However, when currently separating some highly viscous silt, it is easy to clog the filter screen, and it is also easy to have an insufficient filtration separation situation, resulting in a large amount of silt still remaining in the separated water, increasing the burden and reducing the efficiency of subsequent purification work.

[0010] Preferably, a one-way nozzle is provided inside the air jet pipe to prevent sewage from entering.

[0011] Preferably, a fine filter is provided inside the drainage trough, so that the filtered and separated water can be slowly and continuously separated and filtered.

[0012] The present invention provides a rolling sludge high-efficiency solid-liquid separation device, which has the following beneficial effects: (1) A rolling sludge high-efficiency solid-liquid separation device, which can filter the sludge repeatedly and continuously by setting a sludge toggle separation mechanism, so that the sludge is filtered to the filter screen, while the water is reciprocatingly filtered on the right side of the toggle plate and slowly discharged into the drain pipe through the fine filter screen inside the drain trough for collection, thereby realizing the integration of preliminary and fine separation and filtration of the sludge, and realizing efficient solid-liquid automatic separation of the sludge and the internal water, avoiding the problem of a large amount of residue remaining in the water after filtration.

[0013] (2) By setting up a sludge-moving and separating mechanism, when the filter surface is blocked, the sludge between the slidable plate and the filter is slowly pushed through the filter under high pressure. At this time, the filter and the slidable plate are in a high pressure state, and the increase in internal pressure will push the push block to squeeze the elastic plate inside the slide groove, causing the elastic plate to deform, and at the same time, push the air inside the slide groove into the interior of the telescopic rod through the fine air groove, and make multiple telescopic rods telescope and expand, thereby pushing the scraper at one end of the telescopic rod. The scraper is pushed out to slide on the surface of the sliding frame and scrape the filter surface for a certain distance, so that the sludge blocked on the filter surface can be scraped to one side for accumulation and collection.

[0014] (3) By setting up a sludge-pushing separation mechanism, as the filter becomes more clogged, the degree to which the push block pushes and squeezes the air inside the chute can be automatically increased, thereby selectively cleaning the filter surface by pushing the scraper at different distances, further improving the solid-liquid separation efficiency of the filter.

[0015] (4) By setting up a sludge one-way flow mechanism, water can only flow in one direction, ensuring that the water after solid-liquid separation will not flow back, avoiding the secondary pollution of the water, and at the same time making it convenient and quick to carry out repeated and efficient circulation separation between water and sludge.

[0016] (5) By setting up a vibrating sliding collection mechanism, as the shaft rotates, the magnetic block A inside the shaft reciprocates with the magnetic block B under the magnetic repulsion of the same polarity. The magnetic block B will simultaneously push the sliding frame to slide inside the connecting block and push the small elastic plate inside the small slide groove to deform it. The magnetic block A pushes the magnetic block B back and forth, causing the sliding frame to vibrate. The sludge that clogs the surface of the filter can slide quickly to the bottom of the filter with slight vibrations and accumulate in a concentrated manner, thereby reducing the degree of clogging on the surface of the filter.

[0017] (6) By setting up a vibration sliding collection mechanism, the magnetic block A pushes the magnetic block B back and forth, causing the sliding frame to vibrate, and the sludge blocked on the filter surface can slide quickly to the bottom of the filter with slight vibration for centralized accumulation, thereby reducing the degree of blockage on the filter surface. At the same time, the sliding frame will push the air inside the small slide groove through the jet groove and the internal one-way valve A, enter the jet pipe, and be ejected through the one-way nozzle inside the jet pipe, further spraying the sludge adhering to the filter surface and unable to slide off, making it easier to slide on the filter surface and be collected by sliding down along the inclined surface of the filter.

[0023] When in use, the inlet cover 1 on the top of the box body 2 is opened through the thread, and then the sludge that needs to be separated from the solid and liquid is poured into the box body 2, and then the motor is started to drive the rotating shaft 11 to swing back and forth, and the rotating shaft 11 drives the toggle plate 301 to swing back and forth, so that the toggle plate 301 first rotates clockwise to approach the sliding frame 302, and then rotates counterclockwise back to the original position, and reciprocates in this way, so that when the toggle plate 301 is rotated to approach the sliding frame 302 again, the toggle plate 301 will squeeze all the sludge between the sliding frame 302, and pass through the filter screen 309 inside the sliding frame 302 for separation and filtration and enter the right side space of the toggle plate 301, and the sludge is filtered inside the filter screen 309, and when the toggle plate 301 is rotated to approach the sliding frame 302, the toggle plate 301 will squeeze all the sludge between the sliding frame 302, and pass through the filter screen 309 inside the sliding frame 302 for separation and filtration and enter the right side space of the toggle plate 301, and the sludge is filtered inside the filter screen 309 and When the plate 301 rotates back to its original position, the connecting plate 401 inside the toggle plate 301 will be pushed open by the water pressure, and at the same time, the water pressure will first press the connecting plate 401 open, causing the elastic rope 402 to deform, and the connecting plate 401 will be opened. The water pressure out of the connecting plate 401 is less than the filter screen 309, so that when the toggle plate 301 returns to its original position, the water after the sludge is filtered will first push the connecting plate 401 open through the circular hole inside the toggle plate 301 and discharge into the left side of the toggle plate 301, and when the toggle plate 301 rotates again to push the water, the water will pass through the filter screen 309 again for another round of filtration to the right side of the toggle plate 301, and thus reciprocate in this way, so that the sludge can be filtered repeatedly without interruption, thereby filtering the sludge through The filter screen 309 is filtered, and the water is reciprocally filtered at the right side of the toggle plate 301, and is slowly discharged into the drain pipe 10 for collection through the fine filter screen inside the drain groove 9, realizing the integration of preliminary and fine separation and filtration of the sludge, and realizing efficient solid-liquid automatic separation of the sludge and the internal water, avoiding the problem of a large amount of residue in the water after filtration. At the same time, when the surface of the filter screen 309 is blocked, the sludge between the toggle plate 301 and the filter screen 309 passes through the filter screen 309 under a slow and high-pressure state. At this time, the filter screen 309 and the toggle plate 301 are in a high-pressure state, and the increase in internal pressure will push the push block 303 to squeeze the elastic plate 304 inside the slide groove, causing the elastic plate 304 to deform. At the same time, the air inside the chute is pushed into the interior of the telescopic rod 306 through the fine air groove 305, and the multiple telescopic rods 306 are telescoped and expanded, thereby pushing the scraper 307 at one end of the telescopic rod 306. The scraper 307 is pushed out to slide on the surface of the sliding frame 302 and scrapes the surface of the filter 309 for a certain distance, so that the sludge blocked on the surface of the filter 309 can be scraped to one side for accumulation and collection, and as the blockage of the filter 309 worsens, the degree to which the push block 303 pushes and squeezes the air inside the chute can be automatically increased, so that the filter 309 is targeted to be automatically cleaned on the surface of the filter 309 by the different degrees of pushing distance of the scraper 307, thereby further improving the solid-liquid separation efficiency of the filter 309.Meanwhile, as the rotating shaft 11 rotates, the magnet A 501 inside the rotating shaft 11 reciprocally repels the magnet B 502 with the same poles. Under this magnetic repulsion, the magnet B 502 will synchronously push the sliding frame 302 to slide inside the connecting block 310 and push the small elastic plate 503 inside the small chute to deform it. And through the reciprocating push of the magnet A 501 on the magnet B 502, the sliding frame 302 vibrates, and the silt blocking the surface of the filter screen 309 can quickly slide down to the bottom of the filter screen 309 along with the slight vibration for centralized accumulation, reducing the degree of blockage on the surface of the filter screen 309. At the same time, the sliding frame 302 will push the air inside the small chute through the air jet groove 504 and the one-way valve A inside it, into the air jet pipe 505, and spray it out through the one-way nozzle inside the air jet pipe 505, further blowing away the silt that cannot slide off the surface of the filter screen 309 with air, making it easier to slide off the surface of the filter screen 309 and slide down and be collected centrally along the inclined surface of the filter screen 309. The air inside the small chute enters through the communicating air groove 308 and the one-way valve B inside it, and is discharged from the air jet groove 504 and the one-way valve A inside the air jet groove 504 to achieve reciprocating work. Finally, after the work is completed, open the outlet cover 8 on the left side of the base 6 to discharge the remaining sewage, and clean and collect the large amount of silt collected at the bottom of the filter screen 309 through the back door of the box body 2 to achieve the solid-liquid separation of the silt.

Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
