[0001] The utility model relates to a filter assembly of a press-type filter centrifuge, in particular to a filter assembly of a press-type filter centrifuge. Background Art

[0002] The press filter centrifuge is a device used for solid-liquid separation. It combines the two separation principles of filtration and centrifugation and is widely used in the chemical, pharmaceutical, food processing and other industries. Its working principle is to inject the mixture or suspension into the filter basket through the feed port, and then use the drive device to make the filter basket rotate at high speed to generate a strong centrifugal force. Under the action of centrifugal force, solid particles are pushed to the inner wall of the filter basket, while clean liquid flows out through the filter medium to achieve solid-liquid separation. The filter assembly is its core component.

[0003] The filter basket is one of the key components of the press filter centrifuge, usually made of metal or plastic. It is filled with filter media, such as filter cloth, filter paper or filter screen, to capture solid particles or impurities. The pressing device is used to apply pressure to the solid particles in the filter basket to help separate the liquid and squeeze the remaining liquid. This helps to improve the filtration efficiency and the dryness of the solid particles. The filter assembly of the press filter centrifuge is compact in design and easy to operate. It is suitable for various industrial applications of solid-liquid separation, such as chemical, pharmaceutical, food processing and other fields.

[0004] However, in the filter assembly of the traditional press filter centrifuge, the press device often works through the press roller position, usually a pair of parallel cylindrical rollers. Their function is to apply pressure on the filter basket, but this structure driven by the hydraulic system may cause uneven pressure on the solid particles in the filter basket, affecting the final press filtration effect of the centrifuge. Utility Model Content

[0005] In order to make up for the above shortcomings, the utility model provides a filter assembly of a press-type filter centrifuge, aiming to improve the pressing device of the traditional press-type filter centrifuge, which may cause uneven pressure on solid particles in the filter basket and affect the final pressing and filtering effect of the centrifuge.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a filtering component of a squeeze-type filtering centrifuge comprises a sieve cylinder, the upper surface of the sieve cylinder is fixedly connected to a fixed platform, a motor 1 is arranged on the top of the fixed platform, a fixed column is fixedly connected to the output end of the motor 1, the outer wall of the fixed column is rotatably connected to a connecting column, one end of the fixed column is rotatably connected to a screw, the outer wall of the screw is threadedly connected to a sliding column, the bottom of the sliding column is fixedly connected to a pressing platform, the outer wall of the connecting column is rotatably connected to a rotating rod, one end of the rotating rod is rotatably connected to a sliding table, a plurality of slide grooves are opened inside the fixed platform, the slide is slidably connected to the inside of the slide groove, and a fixed component is arranged at the bottom of the sieve cylinder.

[0007] Furthermore, the fixing assembly includes a fixing plate, and the fixing plate is fixedly connected to the bottom of the screen drum.

[0008] Furthermore, a hydraulic rod is provided at the bottom of the fixing plate.

[0009] Furthermore, a rack is fixedly connected to the output end of the hydraulic rod, and the rack is slidably connected inside the fixed plate.

[0010] Furthermore, a plurality of turntables are fixedly connected to the lower surface of the fixed plate, and a rotating shaft is rotatably connected inside the turntable.

[0011] Furthermore, a gear is rotatably connected to the outer wall of the rotating shaft, and the gear is meshed with the rack.

[0012] Furthermore, a plurality of sleeves are fixedly connected to the lower surface of the fixing plate, and a worm is rotatably connected inside the sleeve.

[0013] Furthermore, a plurality of worm gears are fixedly connected to the outer wall of the rotating shaft, and the worm gears are meshed with the worm.

[0014] The utility model has the following beneficial effects:

[0015] 1.

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Reference Figure 1 and Figure 2 The utility model provides an embodiment: a filtering component of a squeeze-type filtering centrifuge, comprising a screen drum 1, a fixed platform 2 is fixedly connected to the upper surface of the screen drum 1, a motor 3 is arranged on the top of the fixed platform 2, a fixed column 4 is fixedly connected to the output end of the motor 3, a connecting column 5 is rotatably connected to the outer wall of the fixed column 4, a screw 6 is rotatably connected to one end of the fixed column 4, a sliding column 20 is threadedly connected to the outer wall of the screw 6, a pressing platform 10 is fixedly connected to the bottom of the sliding column 20, a rotating rod 7 is rotatably connected to the outer wall of the connecting column 5, a sliding table 8 is rotatably connected to one end of the rotating rod 7, a plurality of sliding grooves 9 are opened inside the fixed platform 2, the sliding table 8 is slidably connected inside the sliding groove 9, and a fixed component is arranged at the bottom of the screen drum 1.

[0024] Specifically, the motor 3 drives the fixed column 4 to rotate by outputting a rotating force to the fixed column 4. The rotation of the fixed column 4 also drives the screw 6 at its bottom to rotate. The rotation of the screw 6 causes the slide column 20 to move downward through the threaded connection with the slide column 20. The movement of the slide column 20 causes the inside of the screen drum 1 to be pressed. While the slide column 20 and the connecting column 5 move relative to each other, the rotating rod 7 on the side wall of the connecting column 5 also rotates and changes its own inclination angle. The rotation of the rotating rod 7 drives the slide table 8 to slide in the slide groove 9 inside the fixed table 2. This structure can effectively squeeze and filter the fixed particles inside the screen drum 1. The stability and uniformity of the squeezing process are ensured by the movement of multiple components inside. This design of balanced force downward movement improves the filtering and squeezing effect of the filter assembly and avoids affecting the quality of the final liquid due to uneven squeezing.

[0025] Reference Figure 3 The fixed component includes a fixed plate 11, which is fixedly connected to the bottom of the screen drum 1. A hydraulic rod 12 is arranged at the bottom of the fixed plate 11. A rack 13 is fixedly connected to the output end of the hydraulic rod 12. The rack 13 is slidably connected to the inside of the fixed plate 11. A plurality of turntables 14 are fixedly connected to the lower surface of the fixed plate 11. A rotating shaft 15 is rotatably connected inside the turntable 14. A gear 17 is rotatably connected to the outer wall of the rotating shaft 15. The gear 17 is meshed with the rack 13. A plurality of sleeves 18 are fixedly connected to the lower surface of the fixed plate 11. A worm 19 is rotatably connected inside the sleeve 18. A plurality of worm wheels 16 are fixedly connected to the outer wall of the rotating shaft 15. The worm wheels 16 are meshed with the worm 19.

[0026] Specifically, the hydraulic rod 12 outputs a push-pull force to the rack 13, driving the rack 13 to slide inside the fixed plate 11. While the rack 13 slides, the gear 17 is driven to rotate through the meshing relationship between itself and the gear 17. While the gear 17 rotates, the rotating shaft 15 inside it is driven to rotate inside the turntable 14. The rotation of the rotating shaft 15 can drive multiple worm gears 16 on its outer wall to rotate synchronously. While the worm gear 16 rotates, the meshing relationship between it and the worm 19 drives the worm 19 to slide inside the sleeve 18. The position of the worm 19 is changed to engage or unlock the discharge port of the screen drum 1, making the discharge method of this filter assembly more efficient and safe. This structural design ensures the stability and accuracy of the discharge process and effectively improves the discharge efficiency of the filter assembly.

[0027] Working principle: when it is necessary to perform fixed particle squeezing and filtration on the liquid inside the screen cylinder 1, first start the motor 3, and the motor 3 outputs a rotating force to the fixed column 4 to drive the fixed column 4 to rotate. The fixed column 4 rotates while driving the screw 6 at its bottom to rotate. The screw 6 rotates while driving the slide column 20 to move downward through the threaded connection with the slide column 20. The movement of the slide column 20 can press the inside of the screen cylinder 1. While the slide column 20 and the connecting column 5 move relative to each other, the rotating rod 7 on the side wall of the connecting column 5 rotates and changes its own inclination angle. While the rotating rod 7 rotates, it drives the slide table 8 to slide in the slide groove 9 inside the fixed table 2. This structure can drive the internal fixed body particles to be squeezed. At the same time, through multiple internal movements, the squeezing process is made more stable, and it is able to move downward under balanced force, thereby improving the filtration and squeezing of this filtering component. The effect is achieved by avoiding the influence of uneven pressing on the final liquid quality. When the liquid inside the centrifuge filter assembly needs to be discharged, the hydraulic rod 12 is started. The hydraulic rod 12 outputs a push-pull force on the rack 13 to drive the rack 13 to slide inside the fixed plate 11. While the rack 13 slides, the gear 17 is driven to rotate through the meshing relationship between itself and the gear 17. While the gear 17 rotates, the rotating shaft 15 inside it is driven to rotate inside the turntable 14. The rotation of the rotating shaft 15 can drive multiple worm wheels 16 on its outer wall to rotate synchronously. While the worm wheel 16 rotates, the meshing relationship between it and the worm 19 can drive the worm 19 to slide inside the sleeve column 18. The position of the worm 19 is changed to engage or unlock the discharge port of the screen drum 1, so that the discharge method of this filter assembly is more efficient and safe, and the filtering and squeezing efficiency of this assembly is improved.
