Description

Technical Field

[0001] This utility model relates to the field of liquid filtration technology, specifically a vertical liquid filtration device with self-draining sludge discharge capability. Background Technology

[0002] In industrial sectors such as chemical engineering, food processing, municipal water treatment, and mining and metallurgy, liquid filtration is a core component in ensuring stable production processes, product quality compliance, and environmental emission compliance.

[0003] Traditional vertical filtration devices rely on simple filter screens, filter cloths, or a single filter medium to achieve solid-liquid separation through basic methods such as gravity sedimentation and sieving. However, traditional equipment has obvious shortcomings. It mostly relies on gravity filtration with a single filter medium, which is not thorough in retaining fine and sticky filter cakes. Moreover, the filter cakes tend to accumulate on the surface of the filter medium, forming a thick sludge layer, which leads to a sharp increase in filtration resistance and a decrease in throughput, requiring frequent shutdowns for cleaning. In terms of sludge discharge, traditional gravity discharge or valve discharge is prone to clogging of the discharge port due to the agglomeration of high-viscosity, high-solids-content filter cakes, and often leaks due to wear of seals. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides a vertical liquid filtration device with self-discharging slag, which solves the problems of incomplete slag retention, easy slag clogging, and low automation in traditional vertical filtration devices.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: a vertical, self-discharging liquid filtration device, comprising: a tank, wherein a separation device is rotatably connected to the inner wall of the tank, the separation device compresses the filter residue by rotation, and a discharge device is fixedly connected to the bottom of the tank, the discharge device discharging the residue by compression using the rotation of the separation device; the separation device includes a centrifuge drum, the centrifuge drum being funnel-shaped, and a gear meshing with the outer wall of the centrifuge drum via teeth; the bottom end of the gear is connected to an electric motor via a round shaft. The output end of the machine is rotatably connected, the bottom end of the centrifuge barrel is rotatably connected to the inner wall of the tank, and the outer wall of the circular shaft is rotatably connected to the inner wall of the tank. When the funnel-shaped centrifuge barrel in the device is driven to rotate at high speed by gears and a motor, the centrifugal force can be used to throw the liquid containing residue in the tank towards the inner wall of the centrifuge barrel. Under the action of centrifugal force and pressure difference, the liquid passes through the filter material and is quickly separated, while the filter residue is trapped on the inner wall of the centrifuge barrel. The funnel-shaped structure of the centrifuge barrel, combined with the rotation action, can form a preliminary compression on the filter residue, squeeze out the liquid remaining in the filter residue, and reduce the waste of clear liquid.

[0008] Preferably, the separation device further includes a rotating rod, on the outer wall of which a triangular prism scraper is fixedly connected. The triangular prism scraper is arranged in a circumferential array along the central axis of the rotating rod. A vortex scraper is also fixedly connected to the outer wall of the rotating rod, and an auger is fixedly connected to the outer wall of the rotating rod. The triangular prism scraper, arranged in a circumferential array, can scrape the filter residue on the inner wall of the centrifuge tank in sections as the rotating rod rotates, preventing the filter residue from accumulating in local areas and forming a thick sludge layer. The vortex structure of the vortex scraper can guide the filter residue along the inner wall of the centrifuge tank towards the bottom sludge collection area while scraping the residue, forming a directional conveying and reducing the residence time of the filter residue on the tank wall.

[0009] Preferably, the outer walls of the triangular prism scraper and the vortex scraper are slidably connected to the inner wall of the centrifuge tank. The two work together to keep the filter media surface clean, maintain a stable filtration flow, and avoid frequent shutdowns caused by filter media clogging.

[0010] Preferably, the discharge device includes a fixed cylinder, the inner wall of which is fixedly connected to a discharge pipe, and the bottom end of the discharge pipe is provided with a stop plate.

[0011] Preferably, the top end of the discharge pipe is fixedly connected to the bottom end of the tank, and the inner wall of the discharge pipe is slidably connected to the outer wall of the auger.

[0012] Preferably, a limiting cylinder is fixedly connected to the top of the abutment plate. The outer wall of the limiting cylinder is arranged in a circumferential array along the central axis of the abutment plate. A sliding rod is slidably connected to the inner wall of the limiting cylinder. A compression spring is fixedly connected to the outer wall of the sliding rod. The end of the compression spring away from the sliding rod is fixedly connected to the inner wall of the limiting cylinder. When slag is discharged, the filter slag is pushed open by the pressure of the auger, the compression spring contracts, and the filter slag is discharged smoothly. When there is no slag discharge, the compression spring resets and pushes the abutment plate tightly against the bottom of the discharge pipe to achieve a seal and prevent liquid leakage or external air from entering the tank.

[0013] Beneficial effects

[0014] This invention provides a vertical, self-draining liquid filtration device. It has the following advantages:

[0015] This utility model, through the combination of a separation device and a discharge device, uses a funnel-shaped centrifuge drum driven by a gear transmission and a motor to rotate, achieving rapid initial separation of liquid and sludge through centrifugal force. The triangular column scrapers in a circular array on the rotating rod can scrape off the filter residue from the drum wall in sections, while the vortex scraper can guide the filter residue to the bottom in a directional manner. The two slide against the drum wall, effectively preventing filter media blockage. The auger on the rotating rod slides against the inner wall of the discharge pipe, forcibly pushing the filter residue and squeezing it a second time to reduce the moisture content of the filter residue. The abutment plate, combined with the circular array of limiting cylinders, sliding rods, and compression springs, forms an adaptive sealing structure that automatically opens when sludge is discharged and tightly closes when there is no sludge, preventing blockage and leakage. The low-friction operation of the rotating parts reduces wear, adapting to multiple working conditions and eliminating the need for frequent shutdowns for disassembly and cleaning.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example

[0025] Please see Figure 1-6 This utility model provides a technical solution: a vertical liquid filtration device with self-discharging slag, comprising:

[0026] Tank 1, with a separation device 2 rotatably connected to the inner wall of tank 1. The separation device 2 squeezes the filter residue by rotating. A discharge device 3 is fixedly connected to the bottom of tank 1. The discharge device 3 uses the rotation of the separation device 2 to squeeze and discharge the material. The material to be processed enters from the feed pipe at the top of tank 1, is filtered by the separation device 2, and is discharged by the discharge device 3.

[0027] The separation device 2 includes a centrifuge tank 20, which is funnel-shaped. A gear 21 is meshed with the outer wall of the centrifuge tank 20 via a snap-fit ​​mechanism. The bottom end of the gear 21 is rotatably connected to the output end of a motor via a round shaft. The bottom end of the centrifuge tank 20 is rotatably connected to the inner wall of the tank body 1, and the outer wall of the round shaft is rotatably connected to the inner wall of the tank body 1. When the liquid containing slag enters the tank from the top inlet of the tank body 1, the motor starts, and its output end drives the gear 21 to rotate via the round shaft. The gear 21, through snap-fit, drives the centrifuge tank 20 to rotate at high speed around the inner wall of the tank body 1. Under the action of centrifugal force... In the first step, the liquid containing residue in the tank is quickly thrown towards the inner wall of the centrifuge barrel 20. Under the combined action of centrifugal force and pressure difference inside the tank, the liquid passes through the filter holes on the wall of the filter barrel, becomes clear liquid, and flows down along the inner wall of the tank 1. Finally, it is discharged from the liquid outlet at the bottom of the tank 1, completing the initial solid-liquid separation. The solid filter residue in the liquid is intercepted by the filter medium and adheres to the inner wall of the centrifuge barrel 20. At the same time, the funnel-shaped centrifuge barrel 20 exerts a certain squeezing effect on the filter residue on the inner wall during rotation, squeezing out some of the liquid remaining in the filter residue, further improving the solid-liquid separation effect.

[0028] The separation device 2 also includes a rotating rod 22, with triangular prism scrapers 23 fixedly connected to its outer wall. The triangular prism scrapers 23 are arranged in a circumferential array along the central axis of the rotating rod 22. A vortex scraper 24 is also fixedly connected to the outer wall of the rotating rod 22, as well as an auger 25. The outer walls of the triangular prism scrapers 23 and vortex scrapers 24 are slidably connected to the inner wall of the centrifuge tank 20. As the filtration process continues, filter residue accumulates on the inner wall of the centrifuge tank 20. At this time, the rotating rod 22, which is linked to the motor, rotates synchronously. The triangular prism scrapers 23, arranged in a circumferential array on the outer wall of the rotating rod 22, move in a slidable connection with the inner wall of the centrifuge tank. The inner wall of the centrifuge 20 is slidably connected. When the rotating rod 22 rotates, it scrapes the filter residue on the barrel wall in sections to prevent the filter residue from accumulating in local areas and forming a thick slag layer, thus avoiding a sudden increase in filtration resistance. At the same time, the vortex scraper 24 on the rotating rod 22 also slides in contact with the inner wall of the centrifuge barrel 20. Its vortex structure, while scraping the slag, directionally transports the scraped filter residue along the inner wall of the centrifuge barrel 20 to the slag collection area at the bottom of the barrel, reducing the residence time of the filter residue on the barrel wall, ensuring the cleanliness of the filter medium surface, and maintaining a stable filtration flux. The filter residue transported to the bottom of the centrifuge barrel 20 enters the discharge device 3 area, which is fixedly connected to the bottom of the tank body 1.

[0029] The discharge device 3 includes a fixed cylinder 30, a discharge pipe 31 is fixedly connected to the inner wall of the fixed cylinder 30, a baffle plate 32 is provided at the bottom end of the discharge pipe 31, the top end of the discharge pipe 31 is fixedly connected to the bottom end of the tank 1, the inner wall of the discharge pipe 31 is slidably connected to the outer wall of the auger 25, and the auger 25 at the bottom end of the rotating rod 22 is slidably engaged with the inner wall of the discharge pipe 31. When the rotating rod 22 rotates, the spiral blades of the auger 25 generate a forced pushing force on the filter residue, sending the filter residue into the discharge pipe 31. During the pushing process, the auger 25 will also perform secondary compression on the filter residue to further reduce the moisture content of the filter residue. When the filter residue accumulates to a certain amount in the discharge pipe 31, the pressure generated overcomes the elastic force of the compression spring 35 and pushes the baffle plate 32 to move downward. At this time, the limiting cylinder 33 slides down along the sliding rod 34, the compression spring 35 contracts, the bottom end of the discharge pipe 31 opens, and the filter residue is discharged from the discharge port to the fixed cylinder 30 and then arranged.

[0030] The top of the abutment plate 32 is fixedly connected to the limiting cylinder 33. The outer wall of the limiting cylinder 33 is arranged in a circular array along the central axis of the abutment plate 32. The inner wall of the limiting cylinder 33 is slidably connected to the slide rod 34. The outer wall of the slide rod 34 is fixedly connected to the compression spring 35. The end of the compression spring 35 away from the slide rod 34 is fixedly connected to the inner wall of the limiting cylinder 33. When the filter residue is discharged, the pressure in the discharge pipe 31 decreases, the compression spring 35 returns to its natural extended state, pushes the abutment plate 32 to reset upward, and re-adhere to the bottom of the discharge pipe 31 to achieve a seal. This cycle continues, and the device continuously completes the filtration of the liquid containing residue and the automatic discharge of the filter residue without frequent manual intervention.

[0031] In use, the object to be processed enters from the feed pipe at the top of the tank 1, is filtered by the separation device 2, and is discharged through the discharge device 3;

[0032] When the liquid containing slag enters the tank from the inlet at the top of the tank 1, the motor starts, and its output end drives the gear 21 to rotate through the round shaft. The gear 21 drives the centrifuge barrel 20 to rotate at high speed around the inner wall of the tank 1 through the meshing of the gear teeth. Under the action of centrifugal force, the liquid containing slag in the tank is quickly thrown towards the inner wall of the centrifuge barrel 20. Under the dual action of centrifugal force and pressure difference in the tank, the liquid passes through the filter holes on the wall of the filter barrel, becomes clear liquid, and flows down along the inner wall of the tank 1. Finally, it is discharged from the outlet at the bottom of the tank 1, completing the initial solid-liquid separation. The solid filter residue in the liquid is intercepted by the filter medium and adheres to the inner wall of the centrifuge barrel 20. At the same time, the funnel-shaped centrifuge barrel 20 exerts a certain squeezing effect on the filter residue on the inner wall during the rotation, squeezing out some of the liquid remaining in the filter residue, further improving the solid-liquid separation effect.

[0033] As the filtration process continues, filter residue accumulates on the inner wall of the centrifuge tank 20. At this time, the rotating rod 22, which is linked to the motor, rotates synchronously. The triangular prism scrapers 23 arranged in a circular array on the outer wall of the rotating rod 22 are slidably connected to the inner wall of the centrifuge tank 20. As the rotating rod 22 rotates, it scrapes the filter residue on the tank wall in sections to prevent the filter residue from accumulating in local areas and forming a thick sludge layer, thus avoiding a sudden increase in filtration resistance. At the same time, the vortex scraper 24 on the rotating rod 22 also slides in contact with the inner wall of the centrifuge tank 20. Its vortex structure, while scraping the sludge, directionally transports the scraped filter residue along the inner wall of the centrifuge tank 20 to the sludge collection area at the bottom of the tank, reducing the residence time of the filter residue on the tank wall, ensuring the cleanliness of the filter medium surface, and maintaining a stable filtration flux. The filter residue transported to the bottom of the centrifuge tank 20 enters the discharge device 3 area, which is fixedly connected to the bottom of the tank body 1.

[0034] The auger 25 at the bottom of the rotating rod 22 slides against the inner wall of the discharge pipe 31. As the rotating rod 22 rotates, the spiral blades of the auger 25 generate a forced pushing force on the filter residue, sending the filter residue into the discharge pipe 31. During the pushing process, the auger 25 will also perform secondary compression on the filter residue, further reducing the moisture content of the filter residue. When the filter residue accumulates to a certain amount in the discharge pipe 31, the pressure it generates overcomes the elastic force of the compression spring 35, pushing the abutment plate 32 to move downward. At this time, the limiting cylinder 33 slides down along the sliding rod 34, the compression spring 35 contracts, the bottom of the discharge pipe 31 opens, and the filter residue is discharged from the discharge port to the fixed cylinder 30, and then arranged.

[0035] After the filter residue is discharged, the pressure inside the discharge pipe 31 decreases, the compression spring 35 returns to its natural extended state, pushes the abutment plate 32 upward to reset, and re-adhere to the bottom of the discharge pipe 31 to achieve a seal. This cycle continues, and the device continuously completes the filtration of liquid containing residue and the automatic discharge of filter residue without the need for frequent manual intervention.
