Description

Technical Field

[0001] This invention belongs to the field of solid-liquid separation equipment, specifically a high-frequency, high-mesh-count, inclined vibrating solid-liquid separation equipment. Background Technology

[0002] Solid-liquid separation refers to the process of separating two phases from a solid-liquid system. It is widely used in chemical, pharmaceutical, metallurgical, environmental protection, coal preparation, and livestock manure treatment industries.

[0003] Pig and duck manure contain a large amount of organic matter and emit a strong stench when untreated. This odor not only affects the quality of life of nearby residents, but may also contain harmful gases such as ammonia and hydrogen sulfide, which can harm the environment and human health. Dehydration treatment can reduce the water content of the manure and slow down its fermentation rate, thereby reducing the generation and emission of stench gases.

[0004] Traditional solid-liquid separation equipment often uses the combination of screens and vibrating devices to directly separate and screen raw materials. This makes it difficult to ensure that all raw materials undergo uniform separation, resulting in inconsistent separation of the finished product. At the same time, it is also difficult to avoid the problem of screen holes clogging after multiple uses, which not only affects work efficiency and results, but also requires manual assistance for cleaning each time, causing many inconveniences.

[0005] Therefore, the present invention provides a high-frequency, high-mesh-count, inclined vibrating solid-liquid separation device. Summary of the Invention

[0006] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0007] The technical solution adopted by the present invention to solve its technical problem is as follows: The high-frequency, high-mesh-count, inclined vibrating solid-liquid separation device of the present invention includes a separation frame, a screen and an upper baffle are arranged inside the separation frame, the upper baffle is located above the screen, a feed inlet is opened at the front end of the separation frame, the ends of the screen and the upper baffle are discharge outlets, the screen is inclined, an eccentric vibrator is inclinedly fixed at the top of the separation frame, multiple support frames are fixed at the bottom of the separation frame, a negative pressure cavity exists between the screen and the bottom of the separation frame, an air pump for transmitting airflow to the negative pressure cavity is installed on the outside of the separation frame, multiple drain valves are installed at the bottom of the separation frame, the screen is made of flexible material, and the two ends of the screen can be adjusted for tightness; This setup not only achieves efficient incline-type solid-liquid separation, but also ensures that the material is fully agitated and separated from the solid-liquid material due to the incline motion compared to horizontal or downward movement, reducing uneven material separation. Furthermore, the adjustable screen tension ensures that the screen openings can be mechanically cleaned, allowing the equipment to maintain a high-efficiency solid-liquid separation function over a long period.

[0008] Preferably, a guide plate is fixedly connected to the outlet end of the separation frame, the guide plate is located below the screen, and multiple fans are fixedly connected to the middle of the guide plate. A discharge hood is fixedly connected to the outlet end of the separation frame, and a vacuum cleaner is installed on the top of the discharge hood. During operation, by setting the guide plate, the discharge of the separated solid raw material can be guided, while preventing the solid raw material from entering the negative pressure chamber. At the same time, the fans are set with their outlets facing forward and their suction ports receiving the parallel air from the air pump. This not only ensures the stability and strength of the parallel air in the negative pressure chamber, but also effectively generates suction on the screen. Simultaneously, the air generated by the fan outlet... The high-speed airflow generates an upward blowing force on the fixed material at the outlet, which disperses the powdery material into the discharge hood for collection by a vacuum cleaner. Because the fixed material after solid-liquid separation generally requires further processing, such as secondary dehydration and granulation, the powdery material is easily dispersed into the air during transfer, causing air pollution or producing unpleasant odors. This method not only transfers the powdery material, reducing pollution to the equipment's working environment, but the high-speed airflow at the outlet also dries the fixed material at the outlet, improving the moisture removal effect.

[0009] Preferably, a dividing platform is fixed to the inner bottom of the separating frame, and the top of the dividing platform has an inclined chamfer. The dividing platform is located on the side near the discharge hood. A row of air-cutting grooves is opened on the surface of the screen, and the air-cutting grooves are located above the dividing platform. During operation, the setting of the dividing platform causes the parallel air to move upward when passing through the chamfer of the dividing platform and directly impact the bottom of the screen, and pass through the air-cutting grooves to directly act on the raw material. The high-speed airflow will impact the raw material that is about to exit, and block the raw material to a certain extent, allowing the raw material to undergo more processes in the separation process. At the same time, the high-speed airflow can also carry away moisture, further improving the solid-liquid separation effect.

[0010] Preferably, the top surface of the dividing table is provided with a lifting groove, in which a filter plate is slidably engaged. Multiple heating wires are fixedly connected to the middle of the filter plate, and the top of the filter plate is convex. During operation, the filter plate can be raised so that the air passing through the cutting groove first passes through the heating wires in the filter plate, thus heating the airflow. This allows the raw material to be dried while in contact with it. Since the raw material is close to the outlet at this time, most of the moisture is difficult to discharge. Heating can help the moisture overflow, further ensuring the comprehensiveness of solid-liquid separation.

[0011] Preferably, sealing sleeves are fixed to both sides of the separating frame, and sliding plates are fixed to both sides of the screen. The sliding plates are slidably engaged in the sealing sleeves. Multiple hydraulic rods for controlling the movement of the sliding plates are fixed to the outside of the separating frame. During operation, the sliding plates can be controlled to move by extending and retracting the hydraulic rods. When the two sliding plates slide to the sides, the screen can be kept taut. When the sliding plates move towards the center, the screen becomes relaxed and can be fully deformed and swing significantly under the action of vibration and suction, thereby clearing the blockages in its own screen holes.

[0012] Preferably, the bottom of the dividing platform is provided with multiple horizontally arranged transmission holes, and the bottom of the separating frame is fixedly connected to multiple support frames. A water collection tank is fixedly connected between the bottoms of the multiple support frames. During operation, the transmission holes allow the bottoms of the separating frames to communicate with each other. Under the overall vibration state, the air and water at the bottom can be discharged from the drain valve to the bottom and collected by the water collection tank. The middle part of the support frame is a spring structure, which allows the upper separating frame to vibrate at any angle.

[0013] Preferably, the guide plate is bent, and a partition strip is fixed to the bottom of the screen. The partition strip is made of elastic material, and multiple connecting ropes are fixed between the partition strip and the guide plate. During operation, the bent design of the guide plate better fits the outlet of the screen and guides the discharge of solid raw materials. At the same time, the partition strip blocks the wind from leaking out from the gap between the guide plate and the screen, and the connecting ropes ensure that the partition strip will not be overturned.

[0014] Preferably, the feed end of the separating frame is fixedly connected to a guide rail, and the end of the screen near the guide rail is fixedly connected to multiple sliders. The sliders are slidably engaged in the guide rail, and the output end of the air pump is connected to the negative pressure chamber through the guide rail. During operation, the cooperation of the guide rail and the sliders allows the end of the screen to remain sealed while also allowing for tightness adjustment to ensure that the raw material does not leak downwards from the inlet end. The airflow from the air pump enters the negative pressure chamber horizontally from below the guide rail and forms a stable airflow under the suction of the fan.

[0015] Preferably, a support platform is fixedly connected between the separation frame and the support frame. An input valve is provided on the outer side of the support platform. The input valve is connected to the transmission hole of the separation table through the support platform. During operation, disinfectant cleaning solution can be injected into the transmission hole at the bottom of the separation table through the input valve of the support platform. Some disinfectant solution can be added during the separation process to reduce bacterial growth. Alternatively, during cleaning, the drain valve can be closed first, and disinfectant solution can be injected into the bottom of the separation frame. At the same time, the output direction of the fan can be changed so that the fan exhausts air into the negative pressure chamber. In this way, the air from the air pump and the fan will be concentrated in the negative pressure chamber. At the same time, the filter plate can be raised to heat the airflow. The heated airflow carries the continuously evaporating disinfectant solution. In the negative pressure chamber, due to the lack of an outlet, it can only be squeezed upwards towards the screen and discharged, and finally discharged outwards from the feed port. At this time, the airflow passes through all corners of the equipment, carrying high temperature and disinfectant solution, thereby disinfecting and cleaning the equipment thoroughly, removing a large number of bacteria and odors, and ensuring the cleanliness of the equipment. At the same time, the screen can also be washed by the airflow from bottom to top, ensuring the cleanliness of itself and the leakage hole.

[0016] Preferably, the screen is supported by a shaped mesh as its center, and a covering layer is wrapped around the outside of the shaped mesh. The shaped mesh is woven from multiple interlaced metal wires, and the screen openings are located in the holes formed by the interlacing metal wires. During operation, the center of the screen is supported by the metal wires, providing strong tensile and fracture resistance, and can withstand vibration and deformation. Simultaneously, the holes, located within the interlacing metal wires, do not expand excessively, ensuring that the diameter of the screen openings allows only liquid to pass through. The covering layer can be made of high-temperature resistant resin material to protect the metal wires from direct contact with the raw materials, reducing corrosion. Furthermore, the covering layer is smooth and highly resilient, and can be re-coated after long-term use, resulting in a long service life. The beneficial effects of this invention are as follows: 1. The high-frequency, high-mesh-count, inclined vibrating solid-liquid separation equipment of the present invention, through the arrangement of the separation frame, air pump, and negative pressure chamber, with the screen being inclined as a whole, allows the raw material between the screen and the upper baffle to overcome gravity under vibration, causing the raw material to continuously move uphill towards the discharge port. The screen surface has high-mesh-count sieve holes, preventing large particles from passing through. Under vibration, the material first spreads evenly on the screen surface. At this time, under the action of gravity and vibration, free water on the screen surface will pass through the sieve holes and fall below. A high-speed airflow is then injected into the negative pressure chamber by the air pump. The airflow flows horizontally, entering the negative pressure chamber from the feed inlet. According to Bernoulli's principle, the negative pressure chamber generates a negative pressure suction force on the screen above, causing the raw material above to be subjected not only to gravity but also to the suction force, continuously draining the water from the raw material into the negative pressure chamber. When the water fills the bottom of the separation frame, it is discharged outward from the drain valve. This design not only achieves a highly efficient climbing solid-liquid separation effect, but the climbing movement of the material, compared to horizontal or downward movement, ensures that the material is fully shaken, carrying out a thorough solid-liquid separation process and reducing the problem of uneven material separation.

[0017] 2. The high-frequency, high-mesh, inclined vibrating solid-liquid separation equipment of the present invention, through the setting of a flexible screen with adjustable tension, keeps the screen taut during normal vibration separation, allowing the raw material above the screen to be transported upward under normal vibration. When it is necessary to clean the screen, the screen is released from its taut state, allowing it to relax. Under the action of gravity, the center of the screen droops, and the vibration and negative pressure effects of the equipment are activated. Under the action of vibration, the screen itself shakes and deforms continuously. During the deformation process, the screen holes are continuously pulled or squeezed, which can effectively clean the raw material in the screen holes, or make it fall or crush it into smaller fragments. Combined with the negative pressure adsorption generated at the bottom, it can ensure that all screen holes are cleared. Attached Figure Description

[0020] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0021] like Figures 1 to 8 As shown in the figure, the high-frequency, high-mesh-count, inclined vibrating solid-liquid separation device of the present invention includes a separation frame 1. The separation frame 1 is provided with a screen 11 and an upper baffle 16 inside. The upper baffle 16 is located above the screen 11. A feed inlet 2 is opened at the front end of the separation frame 1. The ends of the screen 11 and the upper baffle 16 are discharge outlets 18. The screen 11 is inclined. An eccentric vibrator 7 is fixedly fixed at the top of the separation frame 1. Multiple support frames 5 are fixedly connected to the bottom of the separation frame 1. There is a negative pressure chamber 12 between the screen 11 and the bottom of the separation frame 1. An air pump 6 for transmitting airflow to the negative pressure chamber 12 is installed on the outside of the separation frame 1. Multiple drain valves 13 are installed at the bottom of the separation frame 1. The screen 11 is made of flexible material, and the two ends of the screen 11 can be adjusted for tightness. The raw materials to be separated are placed between the upper baffle 16 and the screen 11 through the feed inlet 2. The eccentric vibrator 7 is then activated to drive the entire separation frame 1 to vibrate. The eccentric vibrator 7 is installed on the top inclined surface of the separation frame 1, and the resulting vibration is a reciprocating vibration perpendicular to the inclined surface. The screen 11 is set at an angle. Under the action of vibration, the raw materials between the screen 11 and the upper baffle 16 can overcome the effect of gravity and continuously move uphill towards the discharge port 18. The surface of the screen 11 has high-mesh sieve holes, and large particles of raw materials cannot pass through the sieve holes. Under the action of vibration, the material will first spread flat on the surface of the screen 11. At this time, under the action of gravity and vibration, the free water on the surface of the screen 11 will pass through the sieve holes and fall below. As the raw material climbs the slope under vibration, the water film on its surface is broken. Water, due to surface tension, adheres to the surface of solid particles, forming a water film. The intense vibration disrupts this adhesion and surface tension, allowing water that was previously difficult to separate to be separated by gravity. Simultaneously, the vibration causes the material to be repeatedly thrown up and down on the screen surface. During this process, the particles inside the material are no longer tightly packed, but filled with gaps, creating extremely favorable channels for the downward penetration and escape of water. If the material is statically piled up, water is difficult to drain from the bottom. Furthermore, during the throwing motion, each solid particle has more opportunities to contact the surface of the screen 11, thus "scraping" off and expelling the water it carries. Ultimately, the material is more... Dry raw materials are discharged from outlet 18, while a large amount of moisture is discharged downwards through the screen holes, thus achieving solid-liquid separation. To further enhance the separation effect, a high-speed airflow is injected into the negative pressure chamber 12 via air pump 6. The airflow flows horizontally, entering the negative pressure chamber 12 from the direction of inlet 2. According to Bernoulli's principle, the negative pressure chamber 12 generates a negative pressure suction force on the screen 11 above, causing the raw materials above to be subjected not only to gravity but also to the suction force, continuously drawing moisture into the negative pressure chamber 12. When the water fills the bottom of the separation frame 1, it is discharged outwards through drain valve 13. After long-term use, some screen holes on the screen 11 may become blocked, affecting subsequent separation operations. Meanwhile, the screen mesh 11 has small openings, making it inconvenient to clean. By setting up a flexible screen mesh 11, it is kept taut during normal vibration separation, allowing the raw material above the screen mesh 11 to be transported upwards under normal vibration. When cleaning the screen mesh 11 is required, the taut state is released, allowing the screen mesh 11 to relax. Under the action of gravity, the center of the screen mesh 11 droops. At this time, the vibration and negative pressure effects of the equipment are activated. Under the action of vibration, the screen mesh 11 shakes and deforms continuously. During the deformation process, the screen openings are continuously pulled or squeezed, which can effectively clean the raw material in the screen openings, causing it to fall or be crushed into smaller fragments. Combined with the negative pressure adsorption generated at the bottom, it can ensure that all screen openings are cleared.This design not only achieves efficient incline-type solid-liquid separation, but also ensures that the material is fully agitated and separated from the solid-liquid material due to the incline motion compared to horizontal or downward movement, reducing uneven separation. Furthermore, the adjustable tension of the screen 11 allows for mechanical cleaning of the screen openings, ensuring the equipment maintains high-efficiency solid-liquid separation over a long period.

[0022] A guide plate 22 is fixedly connected to the outlet end of the separation frame 1. The guide plate 22 is located below the screen 11. Multiple fans 23 are fixedly connected to the middle of the guide plate 22. A discharge hood 3 is fixedly connected to the outlet end of the separation frame 1. A vacuum cleaner 8 is installed on the top of the discharge hood 3. During operation, the guide plate 22 guides the discharge of the separated solid raw materials while preventing them from entering the negative pressure chamber 12. The fan 23, with its outlet facing forward and its suction port receiving parallel air from the air pump 6, ensures the stability and strength of the parallel airflow within the negative pressure chamber 12, effectively generating suction on the screen 11. Simultaneously, the high-speed airflow from the fan 23's outlet creates an upward-sloping force on the discharged solid raw materials, dispersing the powdery material into the discharge hood 3 for collection by the vacuum cleaner 8. Since the solid raw materials after solid-liquid separation generally require further processing, such as secondary dehydration and granulation, the powdery material is easily dispersed into the air during transfer, causing air pollution or unpleasant odors. This method not only transfers the powdery material, reducing pollution to the equipment's working environment, but also allows the high-speed airflow at the outlet to dry the discharged material, improving moisture removal efficiency.

[0023] A dividing platform 15 is fixed to the bottom inner side of the separating frame 1. The top of the dividing platform 15 is provided with an inclined cut angle. The dividing platform 15 is located on the side near the discharge hood 3. A row of air cutting grooves 21 is provided on the surface of the screen 11. The air cutting grooves 21 are located above the dividing platform 15. During operation, the setting of the dividing table 15 causes the parallel air to move upwards when passing through the cut corner of the dividing table 15, and directly impact the bottom of the screen 11, and pass through the air cutting groove 21, directly acting on the raw material; the high-speed airflow will impact the raw material that is about to exit, and block the raw material to a certain extent, allowing the raw material to undergo more processes in the separation process, while also carrying moisture through the high-speed airflow, further improving the solid-liquid separation effect.

[0024] The top surface of the dividing platform 15 is provided with a lifting groove, and a filter plate 20 is slidably engaged in the lifting groove. Multiple heating wires are fixed in the middle of the filter plate 20, and the top of the filter plate 20 is convex. During operation, the air filter plate 20 can be raised so that the air passing through the air cutter 21 first passes through the heating wire in the air filter plate 20, so that the airflow is heated. In this way, the raw material can be dried at the same time. Since the raw material is close to the outlet at this time, most of the moisture is difficult to discharge. Heating can help the moisture overflow, further ensuring the comprehensiveness of solid-liquid separation.

[0025] Both sides of the separation frame 1 are fixedly connected to sealing sleeves 10, both sides of the screen 11 are fixedly connected to sliding plates 17, the sliding plates 17 are slidably engaged in the sealing sleeves 10, and multiple hydraulic rods 9 for controlling the movement of the sliding plates 17 are fixedly connected to the outside of the separation frame 1. During operation, the sliding plate 17 can be moved horizontally by extending and retracting the hydraulic rod 9. When the two sliding plates 17 slide to the sides, the screen 11 can be kept taut. When the sliding plates 17 move towards the center, the screen 11 becomes relaxed and can be fully deformed and swing significantly under the action of vibration and suction, thereby clearing the blockage in its own screen holes.

[0026] The bottom of the dividing platform 15 is provided with multiple horizontally arranged transmission holes, and the bottom of the separating frame 1 is fixedly connected with multiple support frames 5, and a water collection tank 4 is fixedly connected between the bottoms of the multiple support frames 5. During operation, the transmission holes allow the bottom of the separation frames 1 to be interconnected. Under the overall vibration state, the bottom air and water can be discharged from the drain valve 13 to the bottom and collected by the water collection tank 4. The middle part of the support frame 5 is a spring structure, which allows the upper separation frame 1 to vibrate at any angle.

[0027] The guide plate 22 is bent, and a partition 24 is fixed to the bottom of the screen 11. The partition 24 is made of elastic material, and multiple connecting ropes 25 are fixed between the partition 24 and the guide plate 22. During operation, the bending design of the guide plate 22 better fits the outlet of the screen 11 and guides the discharge of solid raw materials. At the same time, the spacer 24 blocks the wind from leaking out from the gap between the guide plate 22 and the screen 11, and the connecting rope 25 ensures that the spacer 24 will not be overturned.

[0028] The feed end of the separation frame 1 is fixedly connected to a rail 26, and the end of the screen 11 near the rail 26 is fixedly connected to a plurality of sliders 27. The sliders 27 are slidably engaged in the rail 26, and the output end of the air pump 6 is connected to the negative pressure chamber 12 through the rail 26. During operation, the cooperation between the rail 26 and the slider 27 ensures that the end of the screen 11 is sealed while also allowing for tightness adjustment, preventing the raw material from leaking downwards from the inlet. The airflow from the air pump 6 enters the negative pressure chamber 12 horizontally from below the rail 26 and forms a stable airflow under the suction of the fan 23.

[0029] A support platform 14 is fixedly connected between the separation frame 1 and the support frame 5. An input valve is provided on the outer side of the support platform 14. The input valve is connected to the transmission hole of the dividing platform 15 through the support platform 14. During operation, disinfectant cleaning solution can be injected into the transmission hole at the bottom of the dividing table 15 through the input valve of the support platform 14. Some disinfectant solution can be added during the separation process to reduce bacterial growth. Alternatively, during cleaning, the drain valve 13 can be closed first, and disinfectant solution can be injected into the bottom of the separating frame 1. At the same time, the output direction of the blower 23 can be changed so that the blower 23 exhausts air into the negative pressure chamber 12. In this way, the air from the air pump 6 and the blower 23 will be concentrated in the negative pressure chamber 12. At the same time, the air filter plate 20 can be raised to heat the airflow. The heated airflow carries the continuously evaporating disinfectant solution. In the negative pressure chamber 12, due to the lack of an outlet, it can only be squeezed upwards towards the screen 11 and finally discharged outwards from the feed inlet 2. At this time, the airflow passes through all corners of the equipment, carrying high temperature and disinfectant solution, thereby disinfecting and cleaning the equipment thoroughly, removing a large number of bacteria and odors, and ensuring the cleanliness of the equipment. At the same time, the screen 11 can also be washed by the airflow from bottom to top, ensuring its own cleanliness and the cleanliness of the leakage hole.

[0030] The screen 11 is supported by a shaped mesh 28 as the center. The outer side of the shaped mesh 28 is covered with a covering layer 29. The shaped mesh 28 is woven from multiple metal wires. The screen holes of the screen 11 are located in the holes formed by the interlacing of the metal wires. During operation, the center of the screen 11 is supported by metal wires, which has strong tensile and fracture resistance and can withstand vibration and deformation. At the same time, the holes are located in the interlacing of metal wires and will not expand excessively, ensuring that the diameter of the screen holes can only allow liquid to pass through. The covering layer 29 can be made of high-temperature resistant resin material to protect the metal wires from direct contact with the raw materials and reduce corrosion of the metal wires. In addition, the covering layer 29 is smooth and has high toughness. After long-term use, it can be re-coated, which has a long service life.

[0031] During operation, the raw materials to be separated are placed between the upper baffle 16 and the screen 11 through the feed inlet 2. The eccentric vibrator 7 is then activated to drive the entire separation frame 1 to vibrate. The eccentric vibrator 7 is installed on the top inclined surface of the separation frame 1, and the resulting vibration is a reciprocating vibration perpendicular to the inclined surface. The screen 11 is set at an angle. Under the action of vibration, the raw materials between the screen 11 and the upper baffle 16 can overcome the effect of gravity and continuously move uphill towards the discharge port 18. The surface of the screen 11 has high-mesh sieve holes, and large particles of raw materials cannot pass through the sieve holes. Under the action of vibration, the material will first spread flat on the surface of the screen 11. At this time, under the action of gravity and vibration, the free water on the surface of the screen 11 will pass through the sieve holes and fall into the lower... As the raw material climbs the slope under vibration, the water film on its surface is broken. Water, due to surface tension, adheres to the surface of solid particles, forming a water film. Violent vibration disrupts this adhesion and surface tension, allowing water that was previously difficult to separate to be separated by gravity. Simultaneously, the vibration causes the material to be repeatedly thrown up and down on the screen surface. During this process, the particles inside the material are no longer tightly packed but filled with gaps, creating extremely favorable channels for the downward penetration and escape of water. If the material is statically piled up, water is difficult to drain from the bottom. Furthermore, during the throwing motion, each solid particle has more opportunities to contact the surface of the screen, thus "scraping" off and expelling the water it carries. The relatively dry raw material is discharged from the outlet 18, while a large amount of water is discharged downwards through the screen holes, thus achieving solid-liquid separation. To further enhance the separation effect, a high-speed airflow is injected into the negative pressure chamber 12 by the air pump 6. The airflow flows horizontally and enters the negative pressure chamber 12 from the direction of the feed inlet 2. According to Bernoulli's principle, the negative pressure chamber 12 will generate a negative pressure suction force on the screen 11 above, causing the raw material above to be subjected not only to gravity but also to the suction force, continuously draining the water from the raw material into the negative pressure chamber 12. When the water fills the bottom of the separation frame 1, the water will be discharged outwards through the drain valve 13. After long-term use, some screen holes of the screen 11 may become blocked, affecting subsequent separation operations. Meanwhile, the screen mesh 11 has small openings, making it inconvenient to clean. By setting a flexible screen mesh 11, during normal vibration separation, the screen mesh 11 is kept taut, allowing the raw material above the screen mesh 11 to be transported upwards under normal vibration. When cleaning the screen mesh 11 is required, the taut state of the screen mesh 11 is released, allowing the screen mesh 11 to relax. Under the action of gravity, the center of the screen mesh 11 droops. At this time, the vibration and negative pressure effects of the equipment are activated. Under the action of vibration, the screen mesh 11 itself shakes and deforms continuously. During the deformation process, the screen openings are continuously pulled or squeezed, which can effectively clean the raw material in the screen openings, causing it to fall or be crushed into smaller fragments. Combined with the negative pressure adsorption generated at the bottom, it can ensure that all screen openings are cleared.This setup not only achieves efficient incline-type solid-liquid separation, but also ensures that the material is fully shaken and separated from the solid-liquid material due to the incline movement compared to horizontal or downward movement, reducing uneven material separation. Furthermore, the adjustable tension of the screen 11 ensures that the screen holes can be mechanically cleaned, allowing the equipment to maintain a high-efficiency solid-liquid separation function over a long period of time. By setting the guide plate 22, the discharge of the separated solid raw material can be guided, while preventing the fixed raw material from entering the negative pressure chamber 12. At the same time, the fan 23 is set with its air outlet facing forward and its air inlet receiving the parallel air from the air pump 6. This not only ensures the stability and strength of the parallel air in the negative pressure chamber 12, thus effectively generating suction on the screen 11, but also the high-speed airflow generated by the air outlet of the fan 23 will generate an upward oblique blowing force on the fixed raw material at the outlet, thereby blowing the powdery fixed raw material into the discharge hood 3, and then using the vacuum cleaner 8 to collect it. Because the fixed raw material after solid-liquid separation generally needs to undergo subsequent processing, such as secondary dehydration and granulation, the powdery raw material is easily dispersed into the air during transfer, causing air pollution or producing unpleasant odors. In this way, not only can the powdery raw material be transferred, reducing pollution to the working environment of the equipment, but the high-speed airflow at the outlet can also dry the fixed material at the outlet, improving the moisture removal effect. The setting of the dividing table 15 causes the parallel air to move upward when it passes through the cut corner of the dividing table 15 and directly impact the bottom of the screen 11, and pass through the air cutting groove 21 to directly act on the raw material; the high-speed airflow will impact the raw material that is about to exit, and block the raw material to a certain extent, allowing the raw material to undergo more processes in the separation process, while also carrying moisture through the high-speed airflow, further improving the solid-liquid separation effect. The air filter plate 20 can be raised so that the air passing through the air cutter 21 passes through the heating wire in the air filter plate 20 first, so that the airflow is heated. In this way, the raw material can be dried at the same time. Since the raw material is close to the outlet at this time, most of the moisture is difficult to discharge. Heating can help the moisture overflow, further ensuring the comprehensiveness of solid-liquid separation. By extending and retracting the hydraulic rod 9, the sliding plate 17 can be controlled to move horizontally. When the two sliding plates 17 slide to the sides, the screen 11 can be kept taut. When the sliding plates 17 move towards the center, the screen 11 becomes relaxed and can be fully deformed and swing significantly under the action of vibration and suction, thereby clearing the blockage in its own screen holes. The transmission holes allow the bottom of the separation frames 1 to be interconnected. Under the overall vibration state, the bottom air and water can be discharged from the drain valve 13 to the bottom and collected by the water collection tank 4. The middle part of the support frame 5 is a spring structure, which allows the upper separation frame 1 to vibrate at any angle. The bending design of the guide plate 22 better fits the outlet of the screen 11 and guides the discharge of solid raw materials. At the same time, the spacer 24 blocks the wind from leaking out from the gap between the guide plate 22 and the screen 11, and the connecting rope 25 ensures that the spacer 24 will not be overturned. The cooperation between the rail 26 and the slider 27 allows the screen 11 to be sealed at the end while also allowing for tightness adjustment, ensuring that the raw material does not leak downwards from the inlet end; the airflow from the air pump 6 enters the negative pressure chamber 12 horizontally from below the rail 26, and forms a stable airflow under the suction guidance of the fan 23. Disinfectant cleaning solution can be injected into the transmission hole at the bottom of the dividing table 15 through the input valve of the support platform 14. Some disinfectant solution can be added during the separation process to reduce bacterial growth. Alternatively, during cleaning, the drain valve 13 can be closed first, and disinfectant solution can be injected into the bottom of the separating frame 1. At the same time, the output direction of the blower 23 can be changed so that the blower 23 exhausts air into the negative pressure chamber 12. In this way, the air from the air pump 6 and the blower 23 will be concentrated in the negative pressure chamber 12. At the same time, the filter plate 20 can be raised to heat the airflow. The heated airflow carries the continuously evaporating disinfectant solution. In the negative pressure chamber 12, due to the lack of an outlet, it can only be squeezed upwards towards the screen 11 and finally discharged outwards from the feed port 2. At this time, the airflow passes through all corners of the equipment, carrying high temperature and disinfectant solution, thereby disinfecting and cleaning the equipment thoroughly, removing a large number of bacteria and odors, and ensuring the cleanliness of the equipment. At the same time, the screen 11 can also be washed by the airflow from bottom to top, ensuring the cleanliness of itself and the leakage hole. The screen 11 is supported by metal wires at its center, giving it strong tensile and fracture resistance. It can withstand vibration and deformation. Meanwhile, the holes are located in the interlacing of metal wires, preventing excessive expansion and ensuring that the diameter of the screen holes allows liquid to pass through only. The covering layer 29 can be made of high-temperature resistant resin material to protect the metal wires from direct contact with the raw materials and reduce corrosion. At the same time, the covering layer 29 is smooth and has high toughness. After long-term use, it can be re-coated, resulting in a long service life.
