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

[0019] Please see Figures 1-8 This invention provides a high-efficiency solid-liquid separation device, including an outer frame 1, a filter mechanism 2 inside the outer frame 1, the filter mechanism 2 being the main component for solid-liquid separation, a water-supporting mechanism 3 at the bottom inside the outer frame 1 for discharging filtered water, a suction and drainage mechanism 4 outside the outer frame 1 for pumping and draining water, a squeezing mechanism 5 on one side of the outer frame 1 for squeezing the material for further drainage, a squeezing wheel mechanism 6 inside the outer frame 1, and a water distribution pipe 7 in the lower middle part of the outer frame 1.

[0020] The filtration mechanism 2 includes an active conveying shaft 201, which is rotatably connected to the inside of the outer frame 1. A driven conveying shaft 202 is rotatably connected to the inside of the outer frame 1, located on one side of the extrusion mechanism 5. An auxiliary conveying shaft 203 is rotatably connected to the inside of the outer frame 1, located below the active conveying shaft 201. A filter cloth 204 is sleeved between the active conveying shaft 201, the driven conveying shaft 202, and the auxiliary conveying shaft 203. The active conveying shaft 201 acts as the active roller that drives the filter cloth 204 to rotate. The driven conveying shaft 202 and the auxiliary conveying shaft 203 can support the filter cloth 204. The filter cloth 204 is made of 300-mesh polyester long-fiber filter cloth with a thickness of 0.65 mm, which can filter out fine particles. A single roller 205 is rotatably connected to the top inner side of the outer frame 1. The single roller 205 assists in the rotation of the filter cloth 204 and simultaneously presses it.

The motor 209 provides the power for the rotation of the filter cloth 204. The reducer 208 can adjust the speed of the motor 209. The output end of the motor 209 is connected to the input end of the reducer 208. The output end of the reducer 208 is connected to one end of the active conveying shaft 201. The single roller 205 is in contact with the outer surface of the filter cloth 204, and the mating rollers 206 are in contact with the surface of the filter cloth 204.

[0021] The water filter support mechanism 3 includes a support tray 301, which provides an installation position. The support tray 301 is made of 316 stainless steel with a thickness of 1.5 mm. The support tray 301 is externally fixed to the bottom of the inner side of the outer frame 1. The support tray 301 has a drainage groove 302 with a depth of 5 cm inside. A collection groove 303 is provided on one inner end of the support tray 301 to collect the liquid inside the drainage groove 302. A water pipe 304 is connected to one side of the support tray 301 and passes through one side wall of the collection groove 303. The collection groove 303 is equipped with... When filtering, on one side of the drainage trough 302, the motor 209 is started first. After the output end of the motor 209 rotates, it can drive the reducer 208 to rotate. After the reducer 208 reduces the speed, the rotational force is transmitted to the active conveying shaft 201. Then, through the rotation of the filter cloth 204, the driven conveying shaft 202 and the conveying auxiliary shaft 203 can be driven to rotate, thus facilitating the filtration of sewage. The filtered liquid can fall onto the drainage trough 302, where the liquid is collected and gathered inside the collection tank 303, and then discharged through the water pipe 304.

[0022] The filtration and drainage mechanism 4 includes a tank 401, which provides conditions for water inlet and drainage. The tank 401 is externally fixedly connected to one side of the outer frame 1. An internal partition 402 is provided inside the tank 401, separating the internal space. A negative pressure filtration main pipe 403 is provided outside the tank 401, allowing water to enter. A negative pressure filtration pump 404 is externally fixedly connected to the outer frame 1, capable of pumping air. The output end of the pressure filtration pump 404 is connected to a negative pressure filtration pipe 405. The bottom end of the negative pressure filtration pipe 405 is connected to the top of the tank 401. The negative pressure filtration pipe 405 connects the tank 401 and the negative pressure filtration pump 404. A one-way valve 406 is provided on the side of the tank 401 away from the negative pressure filtration main pipe 403. The one-way valve 406 can control the opening and closing of the water circuit. The end of the one-way valve 406 away from the negative pressure filtration main pipe 403 is connected to a one-way drain pipe 407. The system is designed to connect to a water system. The bottom of the one-way drain pipe 407 is connected to the bottom of the outer side of the tank 401. A drain pipe 408 is connected to the bottom of the tank 401 for drainage. The end of the negative pressure filtration main pipe 403 furthest from the tank 401 is connected to one end of the water pipe 304. During vacuum pumping, the negative pressure filtration pump 404 is started first. The input end of the negative pressure filtration pump 404, through the negative pressure filtration pipe 405, directs water from the tank 401 located above the partition 402. The air in the space is evacuated, and the air pressure inside the tank 401 decreases. The filtered water is then pumped into the space above the partition 402 in the tank 401 through the negative pressure filtration pipe 403. When the water level is higher than the one-way valve 406, the one-way valve 406 opens under the action of water pressure, so that the liquid can be transported to the space below the partition 402 inside the tank 401 through the one-way drain pipe 407 and discharged through the drain pipe 408. This process is repeated to achieve water pumping and drainage.

[0023] The extrusion mechanism 5 includes a second reducer 501, which is externally fixed to the outside of the outer frame 1. A second motor 502 is mounted on the top of the second reducer 501. The cooperation between the second reducer 501 and the second motor 502 provides power. An extrusion auger 503 is connected to the output end of the second reducer 501. The rotation of the extrusion auger 503 can extrude liquid from a solid. An extrusion conveying outer frame 504 is located on one side of the inner side of the outer frame 1. A water filter tank 505 is connected to the end of the extrusion conveying outer frame 504 away from the second reducer 501. The water filter tank 505 receives and discharges the liquid filtered through a barrel-shaped screen 506. The barrel-shaped screen 506 has a mesh size of 60 and a wedge-shaped screen bar spacing of 0.25 mm. Millimeters in diameter, the barrel-shaped screen 506 serves a filtering function. A baffle plate 514 is provided at the end of the filter tank 505 away from the outer frame 504 of the extrusion conveyor. Part of the extrusion auger 503 is located within the outer frame 504, and the other part penetrates the barrel-shaped screen 506. The extrusion auger 503 includes a central column 507 and blades on it. The central column 507 is connected to the output end of the reducer 501 and extends through the barrel-shaped screen 506 and the filter tank 505 to the outside of the baffle plate 514. The opening where the central column 507 passes through the baffle plate 514 is the outlet for solid materials. An outlet baffle 515 is provided at the outlet, abutting against the outlet. When the extrusion auger 503 in the barrel-shaped screen 506 spirally conveys the solid material outwards, the solid material is spirally conveyed... At the outlet, an outward squeezing force is applied to the outlet baffle 515, opening the outlet and discharging solid matter. A fixed plate 508 is fixedly connected to the end of the central column 507 furthest from the mudguard 514. A tension adjusting ring 509 is slidably connected to the outside of the fixed plate 508. Multiple support screws 510 are threadedly connected to the periphery of the fixed plate 508. The ends of the multiple support screws 510 furthest from the fixed plate 508 are all fixedly connected to the mudguard 514. A drain pipe 511 is connected to the bottom of the filter tank 505. Water filtered from the barrel-shaped screen 506 is discharged from the drain pipe 511 at the bottom of the filter tank 505. A mudguard spring 513 is sleeved on the outside of the central column 507 between the fixed plate 508 and the mudguard 514. A tension adjusting ring 509 is also connected to the outside of the central column 507 furthest from the mudguard 514. 9 can compress the mudguard spring 513, thereby using the reaction force of the mudguard spring 513 to compress the outlet baffle 515. By compressing the outlet baffle 515, the solid material coming out of the barrel screen 506 is further squeezed to remove moisture, achieving a further dehydration effect. One end of the mudguard spring 513 is fixedly connected to the side of the tension adjusting ring 509 near the mudguard 514, and the other end of the mudguard spring 513 is fixedly connected to the end of the outlet baffle 515 near the tension adjusting ring 509. A scraper 512 is provided on the top of one side of the compression conveying outer frame 504. The top of the scraper 512 contacts the outer surface of the filter cloth 204. When the second motor 502 is started, the output end of the second motor 502 rotates, driving the input end of the second reducer 501 to rotate.The motor 502, driven by a speed reducer, rotates the extrusion auger 503, which, in conjunction with the extrusion conveyor frame 504, extrudes the liquid in the solid waste. The extruded liquid is discharged through the drain pipe 511 at the bottom of the filter tank 505. Loosening the bolts on the tension adjusting ring 509 allows it to move. When the tension adjusting ring 509 moves towards the filter tank 505, it compresses the mudguard spring 513. The compressed spring further squeezes out moisture from the solid material, reducing its moisture content. Moving the tension adjusting ring 509 away from the filter tank 505 releases the mudguard spring 513, releasing the squeezing effect on the solid material and increasing its moisture content. This allows for the regulation of the moisture content of the discharged solid material.

[0024] The extrusion mechanism 6 includes a fixed plate 601, which provides an installation position. One side of the fixed plate 601 is fixedly connected to the inside of the outer frame 1. Multiple extrusion columns 602 are slidably connected inside the fixed plate 601, providing installation positions. A wheel mounting frame 603 is fixedly connected to the top of the extrusion columns 602, providing an installation function. An extrusion wheel 604 is rotatably connected inside the wheel mounting frame 603. The extrusion wheel 604 abuts against the filter cloth 204, serving to fix the filter cloth 204 and facilitate the extrusion of the filter cloth 204. The front-rotating extrusion roller 604 is made of stainless steel and can rotate left and right. A limit bolt 605 is threaded to the end of the extrusion column 602 away from the roller frame 603, providing installation functionality. A buffer spring 606 is sleeved on the outside of the extrusion column 602. The buffer spring 606 uses its own elasticity to provide extrusion force to the extrusion roller 604 to compress the filter cloth 204. One end of the buffer spring 606 is fixedly connected to the top of the fixing plate 601, and the other end is fixedly connected to the bottom of the roller frame 603. There are two extrusion roller mechanisms 6, symmetrically distributed on both sides inside the outer frame 1, used to fix both sides of the filter cloth 204 and assist the filter cloth 204 (…). Figure 2 The view shows a counter-clockwise direction. Figure 1 , 3 4. The view is clockwise) moves upward (rotating from the water distribution pipe 7 towards the squeezing mechanism 5).

[0025] Working principle: During filtration, the solid-liquid mixture is first introduced into the lower middle part of the outer frame 1 through the water distribution pipe 7. Motor 209 is started, and its output rotates, driving the reducer 208 to rotate. The reducer 208 then transmits the rotational force to the drive conveyor shaft 201, causing the filter cloth 204 to rotate. The rotation of the filter cloth 204 then drives the driven conveyor shaft 202 and the auxiliary conveyor shaft 203 to rotate. The filter cloth 204 rotates from the bottom to the top of the outer frame 1 (i.e., from the water distribution pipe 7 towards the extrusion mechanism 5). Figure 2 The view shows a counter-clockwise direction. Figure 1 , 3 (View 4 is clockwise) The solid-liquid mixture coming out of the water distribution pipe 7 is transported upward by the rotation of the filter cloth 204. During the upward transport, the liquid is filtered by the filter cloth 204 and falls into the drainage tank 302 by gravity. Through the synergistic action of the single roller 205 and the two cooperating rollers 206, secondary dehydration can be achieved to improve the dehydration effect. The dehydrated and filtered liquid can fall onto the drainage tank 302, where the liquid is collected and gathered in the collection tank 303, and then discharged through the water pipe 304. When performing vacuum pumping, the negative pressure filtration pump 404 is started first. The input end of the negative pressure filtration pump 404 draws away the air in the space above the partition 402 in the tank 401 through the negative pressure filtration pipe 405. At this time, the air pressure inside the tank 401 decreases, and the filtered water is drawn into the space above the partition 402 in the tank 401 through the negative pressure filtration main pipe 403. When the water level is higher than the one-way valve 406, the one-way valve 406 opens under the action of water pressure, so that the liquid can be transported to the space below the partition 402 inside the tank 401 through the one-way drain pipe 407 and discharged through the drain pipe 408. This step is repeated to achieve pumping and drainage, thereby achieving efficient discharge of the filtrate. After initial liquid separation via filter cloth 204, the solid-liquid mixture moves upward with the filter cloth 204 and enters the extrusion conveyor outer frame 504 through the action of scraper 512. Motor 2 502 is started, and its output rotates, driving the input of reducer 2 501. The reduction speed of motor 2 502 drives the extrusion auger 503 to rotate, coordinating with the extrusion conveyor outer frame 504 to extrude liquid from the solid waste. The extrusion auger 503 further conveys the solid-liquid mixture to the barrel-shaped screen 506 through spiral extrusion. The barrel-shaped screen 506 further filters out the liquid, which then drains through the bottom drain pipe of the filter tank 505. 511 is discharged. The tension adjusting ring 509 can be moved by loosening the bolt on it. When the tension adjusting ring 509 moves towards the filter tank 505, it compresses the mudguard spring 513. The compressed spring further squeezes out the water in the solid material, further reducing its moisture content. Moving the tension adjusting ring 509 away from the filter tank 505 releases the mudguard spring 513, releasing its squeezing effect on the solid material and increasing its moisture content. This allows for the regulation of the moisture content of the discharged solid material. Finally, the solid material is discharged after the mudguard spring 513 further squeezes out the water.
