When the wheel rotates, the strong telescopic rope will slowly wrap around its outside.

[0017] Since the pressure plate is pressed above the discharge plate at this time, the discharge plate will not immediately move upward under the action of the tension of the strong telescopic rope. The strong telescopic rope has strong elasticity and will slowly tighten. When the pressure plate completely leaves the discharge plate, the elastic potential energy in the strong telescopic rope will be converted into kinetic energy for the discharge plate to move upward. At this time, the discharge plate will slide upward quickly. Through the rapid sliding of the discharge plate, the discharge plate can effectively clean up the stubborn impurities adhering to the inner wall of the inner cover.

[0018] The advantages of this design are that, firstly, stubborn impurities will adhere to the surface of the device, reducing its service life. Regular cleaning can extend the service life of the filter cloth and filter plate and reduce replacement and maintenance costs. Secondly, the accumulation of stubborn impurities may cause solid particles to remain and contaminate the liquid. Cleaning impurities can reduce solid residues, avoid product contamination, and improve product quality and purity. Finally, foreign matter, impurities, etc. may cause cross contamination, affecting the production process and product quality. Regular cleaning of impurities can avoid cross contamination and maintain the hygiene and safety of the production environment. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] The technical solution of the utility model will be described clearly and completely in conjunction with the embodiments below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of 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.

[0028] like Figure 1-7 As shown, a filter press for solid-liquid separation includes a separation box 1, an inner cover 3 is fixedly connected to the interior of the separation box 1, a motor 2 is arranged on the side wall of the separation box 1, an outer rod 21 is fixedly connected to one end of the motor 2 close to the separation box 1, an inner rod 22 is slidably connected to the inside of the outer rod 21, one end of the inner rod 22 passes through the side wall of the inner cover 3 and extends into the inner cover 3, one end of the inner rod 22 extending into the inner cover 3 is fixedly connected to a pressure plate 4, the pressure plate 4 is slidably connected to the inside of the inner cover 3, and a discharge assembly 5 is arranged inside the inner cover 3.

[0029] The discharge assembly 5 includes a discharge plate 51, which is slidably connected to the inside of the inner cover 3. A connecting plate 5101 is fixedly connected to the side wall of the discharge plate 51. A strong telescopic rope 52 is fixedly connected to the top of the connecting plate 5101. One end of the strong telescopic rope 52 is fixedly connected to the connecting plate 5101, and the other end of the strong telescopic rope 52 is fixedly connected to a wheel 521. A first belt 53 is sleeved on the outer side of the wheel 521. The wheel 521 is rotatably connected to the side wall at the top of the inner cover 3. One end of the first belt 53 is sleeved on the outer side of the wheel 521, and the other end of the first belt 53 is sleeved on a driven gear 54. A pair of driven gears 54 are provided. The pair of driven gears 54 are rotatably connected to the top and bottom of the inner cover 3 respectively. A chuck 541 is fixedly connected to the side wall of the driven gear 54, and a second belt 55 is sleeved on the outer side of the pair of chucks 541.

[0030] Through the transmission effect of the second belt 55 and the first belt 53, the driven gear 54 below the inner cover 3 drives the driven gear 54 above the inner cover 3 to rotate, and the driven gear 54 above the inner cover 3 drives the wheel 521 to rotate. When the wheel 521 rotates, the strong telescopic rope 52 will slowly wrap around its outside. Since the pressure plate 4 is pressed above the discharge plate 51 at this time, the discharge plate 51 will not immediately move upward under the action of the pulling force of the strong telescopic rope 52. The strong telescopic rope 52 has strong elasticity and will slowly tighten. When the pressure plate 4 completely leaves the discharge plate 51, the elastic potential energy in the strong telescopic rope 52 will be converted into kinetic energy for the upward movement of the discharge plate 51, and the discharge plate 51 will quickly slide upward.

[0031] Through the rapid sliding of the discharge plate 51, the discharge plate 51 can effectively clean up the stubborn impurities adhering to the inner wall of the inner cover 3. A transmission rack 56 is slidably connected to the side wall of the bottom of the inner cover 3. Both ends of the transmission rack 56 are engraved with transmission teeth 561. The transmission teeth 561 and the driven gear 54 are meshed with each other. A rotating rod 57 is fixedly connected to the end of the bottom of the inner cover 3 away from the driven gear 54. The top of the rotating rod 57 is fixedly connected to the anti-dropping nut 581. The side wall of the rotating rod 57 is sleeved with an active gear. The wheel 58, the driving gear 58 and the transmission gear 561 are meshed with each other. A control rack 59 is arranged above the driving gear 58. The control rack 59 is fixedly connected to the side wall of the pressure plate 4.

A control tooth 593 is engraved on the side of the control rack 59 close to the driving gear 58. The control tooth 593 is meshed with the driving gear 58. The driving gear 58 is arranged between the control rack 59 and the transmission rack 56.

[0032] When performing the solid-liquid separation operation, the pressure plate 4 slides toward the feeding pipe 121 under the drive of the motor 2. At this time, the first paddle 591 will first contact the driving gear 58, and the first paddle 591 will push the driving gear 58 away. At this time, the driving gear 58 and the control tooth 593 are not engaged. With the movement of the control rack 59, the pressure plate 4 completes the extrusion of the material. At this time, the second paddle 592 will also contact the driving gear 58 and squeeze the driving gear 58 toward the pressure plate 4. At this time, the driving gear 58 meets the control tooth 593 and engages with each other. When the control rack 59 is driven by the motor 2 to return to its original position, the driving gear 58 will rotate under the drive of the control rack 59. At this time, the transmission rack 56 moves toward the feeding pipe 121 under the drive of the driving gear 58.

[0033] The first paddle 591 and the second paddle 592 are arranged diagonally opposite to each other. The first paddle 591 is arranged on a side of the control rack 59 close to the pressure plate 4 , and the second paddle 592 is arranged on a side of the control rack 59 away from the pressure plate 4 .

[0034] After completing the above work, the first drive of the motor 2 will cause the discharge plate 51 to perform a rising operation. At this time, the discharge plate 51 can lift the extruded material out of the inner cover 3 through the discharge port 13. This operation can achieve the effect of assisting the staff to take out the material.

[0035] After the materials in the inner cover 3 are taken out, the motor 2 can be started again, and the discharge plate 51 can now perform a cleaning operation on the inner cover 3 .

[0036] The advantages of this design are that, firstly, stubborn impurities will adhere to the surface of the device, reducing its service life. Regular cleaning can extend the service life of the filter cloth and filter plate and reduce replacement and maintenance costs. Secondly, the accumulation of stubborn impurities may cause solid particles to remain and contaminate the liquid. Cleaning impurities can reduce solid residues, avoid product contamination, and improve product quality and purity. Finally, foreign matter, impurities, etc. may cause cross contamination, affecting the production process and product quality. Regular cleaning of impurities can avoid cross contamination and maintain the hygiene and safety of the production environment.

[0037] A bracket 11 is fixedly connected to the bottom of the separation box 1, a feeding inlet 12 is opened on the top of the separation box 1, a feeding pipe 121 is fixedly connected to the bottom of the feeding inlet 12, one end of the feeding pipe 121 is fixedly connected to the bottom of the separation box 1, and the other end of the feeding pipe 121 is fixedly connected to the side wall of the inner cover 3, a feeding outlet 122 is opened on the side wall of the inner cover 3, and the feeding outlet 122 is communicated with the feeding pipe 121.

[0038] A discharge port 13 is provided at the top of the separation box body 1, and a pair of rotating shafts 15 are fixedly connected to the top of the separation box body 1. One end of the rotating shaft 15 is fixedly connected to the top of the separation box body 1, and the other end of the rotating shaft 15 is fixedly connected to a cover plate 14. A handle 16 is fixedly connected to the upper surface of the cover plate 14, and the cover plate 14 is arranged in the discharge port 13.

[0039] The feeding pipe 121 is arranged on the side of the inner cover 3 away from the motor 2. The side of the inner cover 3 away from the motor 2 starts with a liquid discharge port 17. The liquid discharge port 17 is arranged below the feeding outlet 122. A liquid collecting hole 19 is arranged inside the separation box 1. The liquid collecting hole 19 is arranged below the liquid discharge port 17. A plug 18 is inserted into the liquid discharge port 17.

[0040] Working principle: When working, first pour the material to be processed into the inner cover 3 through the feeding inlet 12, and then turn on the motor 2.

[0041] Driven by the motor 2, the pressure plate 4 slides toward the feeding pipe 121. At this time, the first paddle 591 will first contact the driving gear 58, and the first paddle 591 will push the driving gear 58 away. At this time, the driving gear 58 and the control tooth 593 are not engaged. With the movement of the control rack 59, the pressure plate 4 completes the extrusion of the material. At this time, the second paddle 592 will also contact the driving gear 58 and squeeze the driving gear 58 toward the direction close to the pressure plate 4. At this time, the driving gear 58 will meet the control tooth 593 to engage with each other.

[0042] When the control rack 59 is driven by the motor 2 to return to its original position, the driving gear 58 will rotate under the drive of the control rack 59. At this time, the transmission rack 56 moves toward the direction close to the feeding pipe 121 under the drive of the driving gear 58. Through the transmission effect of the second belt 55 and the first belt 53, the driven gear 54 below the inner cover 3 drives the driven gear 54 above the inner cover 3 to rotate, and the driven gear 54 above the inner cover 3 drives the wheel 521 to rotate.

[0043] When the wheel 521 rotates, the strong telescopic rope 52 will slowly wrap around its outside. Since the pressure plate 4 is pressed above the discharge plate 51 at this time, the discharge plate 51 will not immediately move upward under the pulling force of the strong telescopic rope 52. The strong telescopic rope 52 has strong elasticity and will slowly tighten. When the pressure plate 4 completely leaves the discharge plate 51, the elastic potential energy in the strong telescopic rope 52 will be converted into kinetic energy for the discharge plate 51 to move upward. At this time, the discharge plate 51 will slide upward rapidly. Through the rapid sliding of the discharge plate 51, the discharge plate 51 can effectively clean up the stubborn impurities adhering to the inner wall of the inner cover 3.

[0044] After completing the above work, the first drive of the motor 2 will cause the discharge plate 51 to perform a rising operation. At this time, the discharge plate 51 can lift the extruded material out of the inner cover 3 through the discharge port 13. This operation can achieve the effect of assisting the staff to take out the material.

[0045] After the materials in the inner cover 3 are taken out, the motor 2 can be started again, and the discharge plate 51 can now perform a cleaning operation on the inner cover 3 .

[0046] During the solid-liquid separation operation, the liquid will flow into the liquid collection hole 19 through the liquid discharge port 17 .

[0047] The above embodiments are only used to illustrate the technical method of the utility model rather than to limit it. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical method of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical method of the utility model.
