[0001] The invention relates to the technical field of wastewater treatment equipment, in particular to semiconductor grinding wastewater solid-liquid separation equipment. Background Art

[0002] With the development of science and technology, the semiconductor industry has become a high value-added, high-tech industry. However, along with the development of the semiconductor industry, the amount of wastewater generated in the semiconductor production process is also increasing, especially the large amount of wastewater containing solid particles generated in the grinding process. In order to protect the ecological environment, the semiconductor wastewater needs to be removed and purified before it is discharged. When removing impurities from semiconductor wastewater, solid-liquid separation equipment is often used to separate the wastewater containing more solid particles.

[0003] Most of the solid-liquid separation equipment in the prior art uses a screen to directly filter the solid impurities in the wastewater. The solid impurities in the wastewater directly impact the screen, and the fixed impurities are easily accumulated on the surface of the filter, thereby affecting the filtering efficiency of the filter. Summary of the invention

[0004] The present application provides semiconductor grinding wastewater solid-liquid separation equipment, which uses centrifugal separation to separate the solid and liquid of wastewater, reduces the possibility of solid impurities accumulating on the filter surface, and ensures the smooth flow of water through the filter.

[0005] The semiconductor grinding wastewater solid-liquid separation equipment provided in this application adopts the following technical solution: Semiconductor grinding wastewater solid-liquid separation equipment comprises a cylinder and a filter cartridge; the filter cartridge is rotatably arranged on the inner wall of the bottom end of the cylinder, and a plurality of through openings are opened on the outer wall of the filter cartridge; a filter screen is installed on the inner wall of each through opening; a cylinder cover arranged on the top of the filter cartridge is detachably installed on the top surface of the cylinder, and a water outlet pipe connected to the cylinder is installed on the bottom surface of the cylinder; a water inlet pipe connected to the filter cartridge is arranged on the cylinder cover; a driving mechanism that can drive the filter cartridge to rotate is arranged at the bottom of the cylinder; a cleaning mechanism that can clean the inner wall of the filter cartridge is arranged inside the filter cartridge.

[0006] By adopting the above technical scheme, when the solid-liquid separation of wastewater is carried out, the wastewater is passed into the filter cartridge through the water inlet pipe, and the filter cartridge is driven to rotate by the driving mechanism to form a centrifugal effect on the wastewater in the filter cartridge. Under the filtering action of the filter screen, the liquid passes through the opening into the cylinder body, and the solid impurities in the wastewater are blocked on the inner wall of the filter cartridge, thereby realizing the solid-liquid separation of the wastewater. When a large number of solid impurities adhere to the inner wall of the filter cartridge, the inner wall of the filter cartridge can be cleaned by the cleaning mechanism to reduce the possibility of the filter screen being blocked by impurities and ensure the smooth flow of water through the filter screen.

[0007] Preferably, a rotating shaft is coaxially fixedly connected to the bottom surface of the filter cartridge; the driving mechanism includes a driving motor; the driving motor is installed on the bottom surface of the cylinder, and the output end of the driving motor is coaxially fixedly connected to the driving shaft; a first spur gear is coaxially fixedly connected to the outer wall of the driving shaft; a second spur gear located at the bottom of the cylinder is coaxially fixedly connected to the bottom end of the rotating shaft; the second spur gear is meshed with the first spur gear.

[0008] By adopting the above technical solution, when performing solid-liquid separation of wastewater, the drive motor is started to drive the drive shaft and the first spur gear to rotate. Under the meshing cooperation of the first spur gear and the second spur gear, the drive shaft drives the rotating shaft and the filter cartridge to rotate, so as to rotate and centrifuge the wastewater in the filter cartridge, thereby separating the solid impurities and liquid in the wastewater.

[0009] Preferably, the cleaning mechanism includes a first motor, a ring and a cleaning brush; the first motor is installed on the top surface of the cylinder cover, and the output end of the first motor is coaxially fixed with a reciprocating screw that penetrates the cylinder cover and extends into the filter cylinder; the ring is sleeved on the outer wall of the reciprocating screw, and the ring and the reciprocating screw are threadedly matched; a limiting rod is fixed to the bottom surface of the cylinder cover; the limiting rod penetrates the ring along the axial direction of the reciprocating screw, and the limiting rod and the ring are slidingly matched; the cleaning brush is coaxially sleeved on the outer wall of the ring, and the cleaning brush can contact the filter.

Under the limiting action of the limiting rod, the ring will drive the cleaning brush to move back and forth along the axial direction of the reciprocating screw. The inner wall of the filter cartridge is cleaned by the reciprocating movement of the cleaning brush, which prompts the impurities adhering to the filter cartridge wall and the filter screen to be cleaned and brushed to the bottom of the filter cartridge and accumulated, thereby reducing the possibility of the filter screen being blocked by solid impurities and ensuring the filtering effect of the filter screen on wastewater.

[0012] By adopting the above technical solution, the reciprocating screw will drive the first rotating shaft to rotate through the first transmission assembly when driving the cleaning brush to move. During the rotation of the first rotating shaft, the scraper will scrape the inner wall of the bottom end of the filter cartridge, thereby reducing the adhesion between impurities and the inner wall of the filter cartridge, reducing the possibility of impurities sticking to the inner wall of the filter cartridge, and facilitating the cleaning of solid impurities.

[0013] Preferably, the first transmission assembly includes a first pulley, a second pulley and a belt; the first pulley is coaxially fixed to the top outer wall of the reciprocating screw; the second pulley is coaxially fixed to the top outer wall of the first rotating shaft; the belt is sleeved on the outside of the first pulley and the second pulley to link the first pulley and the second pulley.

[0014] By adopting the above technical solution, under the cooperation of the first pulley, the second pulley and the belt, the reciprocating screw drives the first rotating shaft to rotate during the rotation process, thereby realizing the transmission of kinetic energy during the rotation of the reciprocating screw and saving the motor cost.

[0016] By adopting the above technical solution, when the driving shaft drives the filter cartridge to rotate to centrifugally treat the wastewater, the driving shaft will drive the second rotating shaft and the slapping plate to rotate through the second transmission assembly. During the rotation, the slapping plate will slap the liquid thrown out from the opening, causing the liquid to be pushed back toward the outer wall of the filter cartridge, forming a recoil effect on the filter screen on the filter cartridge, reducing the possibility of the mesh of the filter screen being blocked, and ensuring the normal operation of the filter screen.

[0018] By adopting the above technical solution, with the cooperation of the first sprocket, the second sprocket and the chain, the driving shaft drives the second rotating shaft to rotate during the rotation process, thereby realizing the transmission of kinetic energy during the rotation of the driving shaft and saving the motor cost.

[0019] Preferably, a rubber sheet is fixedly connected to the outer wall of the striking plate.

[0020] By adopting the above technical solution, the setting of the rubber sheet plays a buffering role on the liquid hitting the slapping plate, reducing the possibility of the liquid being too dispersed due to the excessive impact force of hitting the slapping plate, so that the liquid can have a better recoil effect on the filter screen when rushing towards the filter cartridge.

[0021] Preferably, a threaded hole is provided on the inner wall of the cleaning brush; a through hole matching the threaded hole is opened on the inner wall of the collar; a threaded rod is provided in the through hole, penetrating through the collar wall and being threadedly connected to the threaded hole.

[0022] By adopting the above technical solution, the cleaning brush can be easily installed and removed from the ring with the cooperation of the threaded rod and the threaded hole, making it convenient for the staff to clean or replace the cleaning brush.

[0023] Preferably, a pump body is installed on the bottom surface of the cylinder; a suction pipe is fixedly connected to the input end of the pump body; the end of the suction pipe away from the pump body coaxially penetrates the rotating shaft and the filter cartridge connecting pipe, and the suction pipe rotates in cooperation with the rotating shaft; the output end of the pump body is fixedly connected to a discharge pipe connected to the external environment.

[0024] By adopting the above technical solution, when a large amount of solid impurities are accumulated in the filter cartridge and need to be cleaned, the pump body is started to suck the impurities in the filter cartridge, and the solid impurities are discharged to the outside of the filter cartridge through the suction pipe and the discharge pipe, thereby conveniently realizing the cleaning of the solid impurities.

When a large number of solid impurities adhere to the inner wall of the filter cartridge, the inner wall of the filter cartridge is cleaned by the cleaning mechanism to reduce the possibility of the filter screen being blocked by impurities and ensure the smooth flow of water through the filter screen. 2. When the drive shaft drives the filter cartridge to rotate for centrifugal work, the drive shaft drives the second rotating shaft and the slapping plate to rotate through the second transmission assembly.

When the reciprocating screw drives the cleaning brush to move, the reciprocating screw drives the first rotating shaft to rotate through the first transmission assembly, prompting the scraper to scrape the inner wall of the bottom end of the filter cartridge, reducing the adhesion between the solid impurities and the inner wall of the filter cartridge, thereby reducing the possibility of impurities sticking to the inner wall of the filter cartridge, so that the staff can clean the solid impurities.

DETAILED DESCRIPTION

[0028] The present invention will be further described in detail below with reference to the accompanying drawings. The same components are denoted by the same reference numerals. It should be noted that the terms "front", "rear", "left", "right", "upper", "lower", "bottom" and "top" used in the following description refer to directions in the accompanying drawings, and the terms "inside" and "outside" refer to directions toward or away from the geometric center of a specific component, respectively.

[0029] The present invention discloses a semiconductor grinding wastewater solid-liquid separation device, such as Figure 1 , Figure 2 and Figure 3 As shown, it includes a cylinder 1, a filter cartridge 2, a cylinder cover 3 and a driving mechanism 4. The filter cartridge 2 is vertically rotatably connected to the inner wall of the bottom end of the cylinder 1 through a rotating shaft 23. The filter cartridge 2 is coaxial with the cylinder 1, and the bottom end of the filter cartridge 2 is conical. A plurality of vertically arranged through openings 21 are provided on the outer wall of the filter cartridge 2. The plurality of through openings 21 are evenly spaced along the circumference of the filter cartridge 2, and a filter screen 22 is installed on the inner wall of each through opening 21. The cylinder cover 3 is detachably mounted on the top surface of the cylinder 1 by bolts, and a water inlet pipe 31 that can be communicated with the inside of the filter cartridge 2 is fixedly connected to the top surface of the cylinder cover 3, and a water outlet pipe 11 that is communicated with the cylinder 1 is fixedly connected to the inner wall of the bottom end of the cylinder 1. The driving mechanism 4 is arranged at the bottom of the cylinder 1, and the driving mechanism 4 can drive the rotating shaft 23 to drive the filter cartridge 2 to rotate.

[0030] When solid-liquid separation is performed on wastewater, the wastewater is passed into the filter cartridge 2 through the water inlet pipe 31, and the filter cartridge 2 is driven to rotate by the driving mechanism 4 to form a centrifugal effect on the wastewater in the filter cartridge 2. Under the filtering action of the filter screen 22, the liquid passes through the through port 21 into the cylinder 1 and can be discharged from the cylinder 1 through the water outlet pipe 11. The solid impurities are blocked in the filter cartridge 2 and fall to the bottom of the filter cartridge 2, thereby realizing the solid-liquid separation of the wastewater.

[0031] like Figure 2 and Figure 3 As shown, the bottom end of the rotating shaft 23 vertically penetrates the bottom wall of the cylinder 1 and extends to the bottom of the cylinder 1. The rotating shaft 23 rotates with the bottom wall of the cylinder 1. The driving mechanism 4 includes a driving motor 41, a first spur gear 42 and a second spur gear 43. The driving motor 41 is installed on the bottom surface of the cylinder 1 through a connecting plate. The output end of the driving motor 41 is coaxially fixed with a vertically upward driving shaft 411. The first spur gear 42 is coaxially fixed to the outer side wall of the top end of the driving shaft 411. The second spur gear 43 is coaxially fixed to the outer side wall of the end of the rotating shaft 23 extending to the bottom of the cylinder 1, and the second spur gear 43 is meshed with the first spur gear 42.

[0032] Start the drive motor 41 to drive the drive shaft 411 and the first spur gear 42 to rotate. Under the meshing cooperation of the first spur gear 42 and the second spur gear 43, the drive shaft 411 drives the rotating shaft 23 and the filter cartridge 2 to rotate, causing the wastewater in the filter cartridge 2 to rotate and centrifuge, so as to achieve solid-liquid separation of the wastewater.

[0033] like Figure 2 and Figure 4 As shown, four second rotating shafts 6 located outside the filter cartridge 2 are vertically rotatably connected on the inner wall at the bottom end of the cylinder 1, and the four second rotating shafts 6 are distributed in pairs on the outside of the two sides of the driving shaft 411. Two vertical slapping plates 61 are fixedly connected to the outer wall of each rotating shaft 23. The slapping plates 61 are in a concave arc shape, and a rubber sheet 61 is fixedly connected to the outer wall of each slapping plate 61. Two pairs of second transmission components 62 are arranged on the outer wall of the driving shaft 411. The two pairs of second transmission components 62 can enable the driving shaft 411 to drive the four rotating shafts 23 to rotate respectively.

[0034] When the drive shaft 411 drives the filter cartridge 2 to rotate for centrifugal treatment of wastewater, the drive shaft 411 drives the second rotating shaft 6 and the slapping plate 61 to rotate through the second transmission assembly 62. During the rotation, the slapping plate 61 will slap the liquid thrown out from the opening 21, causing the liquid to be pushed back toward the outer wall of the filter cartridge 2, forming a recoil effect on the filter screen 22 on the filter cartridge 2, and reducing the possibility of the mesh of the filter screen 22 being blocked. The rubber sheet 611 plays a buffering role to prevent the liquid from being too dispersed due to excessive impact force of hitting the slapping plate 61, so as to promote the liquid to rush toward the filter cartridge 2 in strands, thereby having a better recoil effect on the filter screen 22.

[0035] like Figure 2 and Figure 4 As shown, the bottom end of the second rotating shaft 6 passes through the bottom wall of the cylinder 1 and extends to the bottom of the cylinder 1. The second rotating shaft 6 rotates in cooperation with the bottom wall of the cylinder 1. The second transmission assembly 62 includes a first sprocket 621, two second sprockets 622 and a chain 623. The first sprocket 621 is coaxially fixed to the outer wall of the driving shaft 411, and the two second sprockets 622 are coaxially fixed to the outer walls of the bottom ends of the two rotating shafts 23 located on the same side of the driving shaft 411, respectively. The chain 623 is sleeved on the outside of the first sprocket 621 and the two second sprockets 622, and the chain 623 enables the first sprocket 621 and the two second sprockets 622 to be linked.

[0036] With the cooperation of the first sprocket 621 , the two second sprockets 622 and the chain 623 , the driving shaft 411 will drive the second rotating shaft 6 to rotate during the rotation process, thereby realizing the transmission of kinetic energy during the rotation of the driving shaft 411 and saving the motor cost.

[0037] like Figure 2 and Figure 5 As shown, a cleaning mechanism 5 is also provided in the filter cartridge 2, and the cleaning mechanism 5 includes a first motor 51, a collar 52, a cleaning brush 53 and a limiting rod 54. The first motor 51 is vertically mounted on the top surface of the cartridge cover 3, and the output end of the first motor 51 is coaxially fixed with a reciprocating screw 511 which vertically penetrates the cartridge cover 3 and extends into the filter cartridge 2, and the reciprocating screw 511 is rotationally matched with the cartridge cover 3, and the collar 52 is sleeved on the outside of the reciprocating screw 511, and the collar 52 and the reciprocating screw 511 are threadedly matched, and the limiting rod 54 is vertically fixed to the bottom surface of the cartridge cover 3, and the limiting rod 54 vertically penetrates the collar 52, and the outer wall of the limiting rod 54 is slidingly matched with the collar 52, and the cleaning brush 53 is annular, and the cleaning brush 53 is coaxially sleeved on the outer wall of the collar 52, and the bristles on the outer wall of the cleaning brush 53 can contact the inner wall of the filter cartridge 2 and the filter screen 22.

[0038] After the solid impurities in the wastewater are separated from the liquid, the first motor 51 is started to drive the reciprocating screw 511 to rotate. Under the limiting guiding action of the limiting rod 54, the ring 52 will drive the cleaning brush 53 to reciprocate in the vertical direction. During the movement of the ring 52, the cleaning brush 53 will clean the inner wall of the filter cartridge 2 and the filter screen 22, causing the solid impurities adhered to the inner wall of the filter cartridge 2 and the filter screen 22 to fall to the bottom of the filter cartridge 2, thereby reducing the possibility of the filter screen 22 being blocked by solid impurities and ensuring the smooth water permeability of the filter screen 22.

[0039] like Figure 2 and Figure 5As shown, the bottom surface of the drum cover 3 is rotatably connected with a first rotating shaft 55, the first rotating shaft 55 is coaxially arranged with the filter cartridge 2, the bottom end of the first rotating shaft 55 extends into the filter cartridge 2, the outer side wall of the bottom end of the first rotating shaft 55 is fixedly connected with a scraper 56 through a connecting rod 551, the scraper 56 contacts the conical inner wall of the bottom end of the filter cartridge 2, and the top end of the first rotating shaft 55 is provided with a first transmission assembly 57 that can drive the reciprocating screw rod 511 to drive the first rotating shaft 55 to rotate. The first transmission assembly 57 includes a first pulley 571, a second pulley 572 and a belt 573. The first pulley 571 is coaxially fixed to the outer side wall of the top end of the reciprocating screw rod 511, and the second pulley 572 is coaxially fixed to the outer side wall of the top end of the first rotating shaft 55. The belt 573 is tensioned and sleeved on the outside of the first pulley 571 and the second pulley 572, and the belt 573 links the first pulley 571 and the second pulley 572.

[0040] With the cooperation of the first pulley 571, the second pulley 572 and the belt 573, the reciprocating screw 511 drives the first rotating shaft 55 to rotate during the rotation process, prompting the scraper 56 on the outer wall of the first rotating shaft 55 to scrape the conical inner wall of the filter cartridge 2, thereby reducing the adhesion between the solid impurities and the inner wall of the filter cartridge 2, making it convenient for the staff to clean the solid impurities in the filter cartridge 2.

[0041] like Figure 2 , Figure 5 and Figure 6 As shown, a pump body 7 is installed on the bottom surface of the cylinder 1, and a suction pipe 71 is fixedly connected to the output end of the pump body 7. A discharge pipe 72 connected to the external environment is fixedly connected to the output end of the pump body 7. The end of the suction pipe 71 away from the pump body 7 vertically penetrates the rotating shaft 23 and extends to the inside of the filter cartridge 2. The suction pipe 71 connects the pump body 7 and the filter cartridge 2, and the suction pipe 71 rotates coaxially with the rotating shaft 23.

[0042] When a large amount of solid impurities accumulate in the filter cartridge 2, the pump body 7 is started to suck the solid impurities accumulated inside the filter cartridge 2. The solid impurities are transported out of the filter cartridge 2 through the suction pipe 71 and the discharge pipe 72, thereby conveniently cleaning the solid impurities in the filter cartridge 2.

[0043] like Figure 5 and Figure 7 As shown, four threaded holes 531 are provided on the side wall of the cleaning brush 53 away from the bristles, and four through holes 521 that can cooperate with the threaded holes 531 are provided on the inner wall of the ring 52. A threaded rod 522 that horizontally passes through the side wall of the ring 52 can be set in each through hole 521, and the threaded rod 522 can be threadedly connected to the inner wall of the threaded hole 531 to fix the cleaning brush 53.

[0044] The cleaning brush 53 can be easily installed on the collar 52 by passing the threaded rod 522 through the through hole 521 and screwing it into the threaded hole 531. The installation method is simple and convenient, and it is easy to disassemble, so that the staff can clean and replace the cleaning brush 53 when necessary.

[0045] Working principle: When solid-liquid separation is performed on wastewater, the wastewater is passed into the filter cartridge 2 through the water inlet pipe 31, and the drive motor 41 is started to drive the drive shaft 411 and the first spur gear 42 to rotate. Under the meshing cooperation of the first spur gear 42 and the second spur gear 43, the drive shaft 411 drives the rotating shaft 23 and the filter cartridge 2 to rotate, thereby forming a centrifugal effect on the wastewater in the filter cartridge 2, and the liquid in the wastewater passes through the filter screen 22 at the opening 21 and enters the cylinder 1, and the solid impurities in the wastewater are blocked on the inner wall of the filter cartridge 2, thereby achieving solid-liquid separation of the wastewater; When the drive shaft 411 drives the filter cartridge 2 to rotate, under the cooperation of the first sprocket 621, the second sprocket 622 and the chain 623, the drive shaft 411 drives the second rotating shaft 6 and the slapping plate 61 to rotate. During the rotation process, the slapping plate 61 will slap the liquid thrown out of the filter cartridge 2, causing the liquid to be pushed back toward the filter cartridge 2, forming a recoil effect on the filter screen 22 on the filter cartridge 2, and reducing the possibility of the mesh of the filter screen 22 being blocked by solid impurities; When there are many solid impurities adhering to the inner wall of the filter cartridge 2, the first motor 51 is started to drive the reciprocating screw rod 511 to rotate. Under the limiting guiding action of the limiting rod 54, the collar 52 drives the cleaning brush 53 to reciprocate in the vertical direction and clean the inner wall of the filter cartridge 2 and the filter screen 22, so that the impurities adhering to the inner wall of the filter cartridge 2 and the filter screen 22 fall to the bottom of the filter cartridge 2. During the rotation of the reciprocating screw rod 511, the first rotating shaft 55 is driven to rotate synchronously through the cooperation of the first pulley 571, the second pulley 572 and the belt 573, so that the scraper 56 is scraped to the inner wall of the bottom end of the filter cartridge 2, so as to reduce the adhesion between the impurities and the inner wall of the filter cartridge 2, so as to clean the solid impurities. When a large amount of impurities are accumulated in the filter cartridge 2 and need to be cleaned, the pump body 7 is started to suck the impurities in the filter cartridge 2, and the solid impurities are discharged out of the filter cartridge 2 through the suction pipe 71 and the discharge pipe 72, thereby conveniently realizing the cleaning of the solid impurities in the filter cartridge 2.

[0046] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
