A separator for a wet sander

Abstract

This utility model relates to the field of ultrafine powder grinding technology, specifically to a separator for a wet grinding mill. It includes a separator assembly comprising a housing with a top opening and a sealing cover on top of the housing. In this utility model, when a servo motor drives a lead screw to rotate, the vertical groove constrains the movement direction of the connecting plate, causing the nut to move vertically upwards along the lead screw, thereby synchronously raising the sealing cover. When the connecting plate moves to the position where the vertical groove and the horizontal groove connect, the horizontal groove releases the constraint on the rotation of the connecting plate, and the connecting plate then rotates into the horizontal groove, causing the sealing cover to detach from the housing and rotate around the lead screw axis. When the connecting plate reaches the end of the horizontal groove, the servo motor stops running. At this point, the sealing cover has completely moved out from directly above the housing, allowing the operator to easily remove the separator sieve from the housing, improving the replacement efficiency of the separator sieve and making operation and maintenance simpler and more efficient.

Description

Technical Field

[0001] This utility model relates to the field of ultrafine powder grinding technology, and more specifically, to a separator for a wet grinding machine. Background Technology

[0002] Ultrafine powder refers to extremely fine solid particles with particle sizes typically in the micrometer or nanometer range, which are usually prepared using wet grinding mills in industry.

[0003] Even in ultrafine powders produced by wet grinding mills, there are still large impurities. Therefore, in subsequent processes, a separator with a separating screen is required to separate the finished product from the large impurities. To prevent the large impurities from clogging the separating screen, the impurities need to be cleaned regularly. However, with existing technology, the wet grinding mill must be stopped and the grinding operation interrupted when cleaning the impurities, which makes it impossible for the equipment to maintain continuous operation and affects production efficiency. At the same time, after long-term use, the screen holes are easily clogged by materials. Since the screen hole diameter is extremely small, the separating screen can only be removed from the separator for cleaning, which is quite inconvenient. Utility Model Content

[0004] The purpose of this invention is to provide a separator for a wet grinding mill to solve the problems mentioned in the background art.

[0005] 1. When cleaning impurities from the separator, the wet grinding mill must be stopped and the grinding operation interrupted, which prevents the equipment from running continuously and affects production efficiency;

[0006] 2. After long-term use, the screen holes of the separator are easily blocked by materials. When cleaning the separator, it is necessary to disassemble the separator from the separator, which is inconvenient.

[0007] To address the above problems, the present invention aims to provide a separator for a wet grinding mill, comprising a separator assembly. The separator assembly includes a shell with a top opening, a sealing cover on the top of the shell, a conveying assembly and a rinsing assembly on the upper side of the sealing cover, a discharge assembly near the bottom of the shell sidewall, and a slag discharge assembly at the bottom of the shell. A cylindrical separating screen is coaxially arranged inside the shell. When the separator assembly is in operation, the conveying assembly transports the material ground by the wet grinding mill into the separating screen, which separates the material into finished product and impurities. The material passes through the separator screen and enters the discharge assembly for discharge. Impurities accumulate inside the shell. When the separator assembly is in the cleaning state, the conveying assembly directly conveys the material ground by the wet grinder to the discharge assembly for discharge. At the same time, the flushing assembly washes away the impurities accumulated inside the shell, allowing the washed impurities to be discharged through the slag discharge assembly. A displacement mechanism is provided on the outside of the shell. The displacement mechanism is used to drive the sealing cover to move vertically and rotate around the axis of the displacement mechanism. When the displacement mechanism drives the sealing cover to move to the top of the shell, the sealing cover blocks the opening of the shell, and the lower side wall of the sealing cover cooperates with the inner wall of the shell to fix the position of the separator screen.

[0008] As a further improvement to this technical solution, the displacement mechanism includes an assembly cylinder fixedly mounted on the outer circumferential wall of the housing by a bracket. A lead screw is coaxially rotatably mounted inside the assembly cylinder, and a servo motor is fixedly mounted at the bottom of the assembly cylinder. The output shaft of the servo motor rotatably passes through the bottom of the assembly cylinder and is coaxially fixedly connected to the lower end of the lead screw through a coupling. A nut is threaded onto the lead screw.

[0009] As a further improvement to this technical solution, the displacement mechanism also includes a vertical groove and a horizontal groove formed on the circumferential side wall of the assembly cylinder. The horizontal groove and the vertical groove form an inverted L-shaped groove. A connecting plate is horizontally fixed on the nut. The other end of the connecting plate passes through the inverted L-shaped groove and is fixed on the sealing cover.

[0010] As a further improvement to this technical solution, the conveying assembly includes a third pneumatic valve fixedly installed on the side wall of the sealing cover. When the sealing cover blocks the opening of the housing, the outlet of the third pneumatic valve passes through the side wall of the sealing cover and extends into the interior of the separating screen. A three-way pipe with one inlet and two outlets is provided above the third pneumatic valve. One outlet of the three-way pipe is fixedly connected to the inlet pipe of the third pneumatic valve, and the other outlet of the three-way pipe is fixedly connected to a second pneumatic valve.

[0011] As a further improvement to this technical solution, the feed inlet of the three-way pipe is fixedly connected to the first discharge pipe through the first quick-connect coupling, and the other end of the first discharge pipe is connected to the discharge port of the wet grinding machine through a flexible hose.

[0012] As a further improvement to this technical solution, the discharge assembly includes a fifth pneumatic valve fixedly installed on the outer circumference of the sealing cover. The inlet of the fifth pneumatic valve passes through the side wall of the housing and extends into the interior of the housing. The outlet of the fifth pneumatic valve is fixedly connected to a second discharge pipe. The second discharge pipe and the fifth pneumatic valve form an inverted T-shaped structure. The outlet of the second pneumatic valve is fixedly connected to the upper end of the second discharge pipe through a second quick-connect coupling.

[0013] As a further improvement to this technical solution, the rinsing assembly includes a fourth pneumatic valve fixedly installed on the side wall of the sealing cover. When the sealing cover blocks the opening of the housing, the outlet of the fourth pneumatic valve passes through the side wall of the sealing cover and extends into the interior of the separation screen, and the inlet of the fourth pneumatic valve is fixedly connected to a rinsing water pipe through a third quick-connect coupling.

[0014] As a further improvement to this technical solution, the slag discharge assembly includes a slag discharge pipe fixedly installed at the bottom of the housing, and a first pneumatic valve is fixedly installed at the lower end of the slag discharge pipe.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] 1. The separator used in this wet grinding mill allows the finished material to pass through the screen holes and enter the gap between the outer wall of the screen and the inner wall of the shell after the material discharged from the outlet of the wet grinding mill enters the separator screen. Then, it enters the mud storage tank through the fifth pneumatic valve and the second discharge pipe. This process effectively improves the purity of the material in the mud storage tank and the quality of the final product. When the separator assembly is switched to the cleaning state, the material after grinding by the wet grinding mill directly enters the mud storage tank through the second discharge pipe. At the same time, the flushing assembly is activated to flush the impurities accumulated in the shell. The flushed impurities are discharged into the external impurity collection tank through the slag discharge assembly to avoid excessive accumulation of impurities that may clog the separator screen and ensure the long-term normal use of the separator screen. At the same time, the equipment can maintain continuous operation and production during the cleaning of material impurities without affecting the production efficiency of the wet grinding mill.

[0017] 2. The separator used in this wet grinding machine, when the servo motor drives the lead screw to rotate, the vertical groove constrains the movement direction of the connecting plate, causing the nut to move vertically upward along the lead screw, thereby driving the sealing cover to rise synchronously. When the connecting plate moves to the position where the vertical groove and the horizontal groove connect, the horizontal groove releases the constraint on the rotation of the connecting plate, and the connecting plate then rotates into the interior of the horizontal groove, driving the sealing cover to detach from the housing. At the same time, it rotates around the axis of the lead screw. When the connecting plate rotates to the end of the horizontal groove, the servo motor stops running. At this time, the sealing cover has been completely moved out of the top of the housing, and the operator can easily remove the separator screen inside the housing, improving the replacement efficiency of the separator screen and making operation and maintenance simpler and more efficient.

[0030] 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.

[0031] Example 1

[0032] Please see Figure 1As shown, the purpose of this embodiment is to provide a separator for a wet grinding mill, including a separator assembly 1. The separator assembly 1 includes a housing 11 with a top opening, a sealing cover 12 disposed above the housing 11, a conveying assembly and a rinsing assembly disposed on the upper side of the sealing cover 12, a discharge assembly disposed on the side wall of the housing 11 near the bottom, and a slag discharge assembly disposed at the bottom of the housing 11. (Refer to...) Figure 2 A cylindrical separating screen 3 is coaxially arranged inside the shell 11. There is a gap between the outer circumference of the separating screen 3 and the inner circumference of the shell 11, and the lower side of the separating screen 3 is in contact with the inner wall of the shell 11. Several screen holes are opened on the separating screen 3. The inner diameter of the screen holes corresponds to the expected particle size of the finished material. Therefore, the separating screen 3 only allows the finished material in the material to pass through.

[0033] Separator assembly 1 has an operating state and a cleaning state:

[0034] When the separator assembly 1 is in operation, the conveying assembly conveys the material ground by the external wet grinder to the inside of the separating screen 3. The separating screen 3 separates the material into finished product and impurities. The finished product passes through the separating screen 3 and enters the discharge assembly to be discharged into the external mud storage tank, while the impurities accumulate inside the shell 11.

[0035] When the separator assembly 1 is in the cleaning state, the conveying assembly directly conveys the material ground by the external wet grinder to the discharge assembly for discharge. At the same time, the flushing assembly washes the impurities accumulated inside the shell 11, so that the washed impurities are discharged through the slag discharge assembly to the external impurity collection tank, thus avoiding excessive accumulation of impurities in the separator 3 and clogging of the separator 3.

[0036] The structure of the conveying assembly is detailed below. The conveying assembly includes a third pneumatic valve 142 fixedly installed on the upper side wall of the sealing cover 12. When the sealing cover 12 blocks the opening of the housing 11, the outlet of the third pneumatic valve 142 passes through the side wall of the sealing cover 12 and extends into the interior of the separation screen 3. A three-way pipe 14 with one inlet and two outlets is provided above the third pneumatic valve 142. One outlet of the three-way pipe 14 is fixedly connected to the inlet pipe of the third pneumatic valve 142, and the other outlet of the three-way pipe 14 is fixedly connected to a second pneumatic valve 141. The inlet of the three-way pipe 14 is fixedly connected to a first outlet pipe 13 through a first quick-connect coupling 131. The other end of the first outlet pipe 13 is connected to the outlet of an external wet grinder through a hose.

[0037] The structure of the discharge assembly is detailed below. The discharge assembly includes a fifth pneumatic valve 18 fixedly installed on the outer circumference of the sealing cover 12. The inlet of the fifth pneumatic valve 18 passes through the side wall of the housing 11 and extends into the interior of the housing 11. The inlet of the fifth pneumatic valve 18 corresponds to the outer space of the separating screen 3. The outlet of the fifth pneumatic valve 18 is fixedly connected to a second discharge pipe 17. The second discharge pipe 17 and the fifth pneumatic valve 18 form an inverted T-shaped structure. The outlet of the second pneumatic valve 141 is fixedly connected to the upper end of the second discharge pipe 17 through a second quick-connect coupling 143. The lower end of the second discharge pipe 17 is connected to the interior of the external mud storage tank.

[0038] When the separator assembly 1 is in operation, the third pneumatic valve 142 is opened and the second pneumatic valve 141 is closed. The material discharged from the outlet of the external wet grinder enters the first discharge pipe 13 through the hose, and then enters the interior of the separator screen 3 through the three-way pipe 14 and the third pneumatic valve 142 in sequence. The finished material in the material enters the gap between the outer wall of the separator screen 3 and the inner wall of the shell 11 through the screen holes of the separator screen 3, and then enters the mud storage tank for collection through the fifth pneumatic valve 18 and the second discharge pipe 17 in sequence. Large particles of impurities in the material are retained and accumulated inside the separator screen 3 because they cannot pass through the screen holes.

[0039] The structure of the rinsing assembly is detailed below. The rinsing assembly includes a fourth pneumatic valve 16 fixedly installed on the upper side wall of the sealing cover 12. When the sealing cover 12 blocks the opening of the housing 11, the discharge port of the fourth pneumatic valve 16 passes through the side wall of the sealing cover 12 and extends into the interior of the separation screen 3. The inlet of the fourth pneumatic valve 16 is fixedly connected to a rinsing water pipe 15 through a third quick-connect coupling 151. The other end of the rinsing water pipe 15 is connected to a water pump via a hose. The pump's suction pipe is connected to an external water source.

[0040] The structure of the slag discharge assembly is detailed below. The slag discharge assembly includes a slag discharge pipe 111 fixedly installed at the bottom of the housing 11. The upper end of the slag discharge pipe 111 passes through the lower side wall of the housing 11 and extends into the interior of the separation screen 3. A first pneumatic valve 112 is fixedly installed at the lower end of the slag discharge pipe 111.

[0041] The first pneumatic valve 112, the second pneumatic valve 141, the third pneumatic valve 142, the fourth pneumatic valve 16 and the fifth pneumatic valve 18 in this device are all controlled by an external operating system. The operating system can set the discharge cycle of impurities inside the shell 11 according to the impurity content in the material.

[0042] When it is necessary to discharge impurities inside the shell 11, the operating system controls the separator assembly 1 to switch to the cleaning state: close the third pneumatic valve 142 and the fifth pneumatic valve 18, and simultaneously open the fourth pneumatic valve 16, the second pneumatic valve 141 and the first pneumatic valve 112. At this time, the material discharged from the outlet of the external wet grinder is discharged directly into the mud storage tank for collection through the first discharge pipe 13, the three-way pipe 14, the second pneumatic valve 141 and the second discharge pipe 17. At the same time, after opening the fourth pneumatic valve 16, the water pump is started to deliver water through the hose to the inside of the flushing water pipe 15. The water flows into the inside of the separator screen 3 through the flushing water pipe 15 and the fourth pneumatic valve 16 to flush the impurities accumulated inside the shell 11. The flushed impurities, along with the water, flow into the external impurity collection tank for collection through the slag discharge pipe 111 and the first pneumatic valve 112.

[0043] After rinsing is completed, the operating system controls the separator assembly 1 to switch back to the working state: open the third pneumatic valve 142 and the fifth pneumatic valve 18, and at the same time close the fourth pneumatic valve 16, the second pneumatic valve 141 and the first pneumatic valve 112, restoring the normal operation of the equipment.

[0044] This design significantly improves the purity of materials and product quality after passing through separator component 1. At the same time, the equipment can operate continuously without affecting the production efficiency of the external wet grinding mill during the cleaning of material impurities.

[0045] After long-term use, the screen holes of the separator 3 may become clogged with material. At this time, the separator 3 needs to be disassembled and cleaned. To facilitate the disassembly and replacement of the separator 3, a displacement mechanism 2 is provided on the outside of the housing 11. The displacement mechanism 2 is used to drive the sealing cover 12 to move vertically and rotate around the axis of the displacement mechanism 2.

[0046] The structure of displacement mechanism 2 is detailed below, referring to... Figures 4-6 The displacement mechanism 2 includes an assembly cylinder 21 fixedly mounted on the outer circumferential wall of the housing 11 by a bracket. A lead screw 25 is coaxially rotatably mounted inside the assembly cylinder 21, and a servo motor 22 is fixedly mounted at the bottom of the assembly cylinder 21. The servo motor 22 is electrically connected to an external operating system. The output shaft of the servo motor 22 rotates through the bottom of the assembly cylinder 21 and is coaxially fixedly connected to the lower end of the lead screw 25 through a coupling. A nut 26 is threaded onto the lead screw 25. The displacement mechanism 2 also includes a vertical groove 211 and a horizontal groove 212 formed on the circumferential side wall of the assembly cylinder 21. The horizontal groove 212 and the vertical groove 211 form an inverted L-shaped groove. A connecting plate 23 is horizontally fixed on the nut 26. The other end of the connecting plate 23 passes through the inverted L-shaped groove and is fixedly mounted on the sealing cover 12.

[0047] When the separator assembly 1 is in the working state and the cleaning state, the sealing cover 12 is in contact with the upper side wall of the housing 11. The sealing cover 12 blocks the opening of the housing 11, and the lower side wall of the sealing cover 12 cooperates with the inner wall of the housing 11 to fix the position of the separating screen 3, ensuring that the separating screen 3 can perform the function of screening materials. At this time, the connecting plate 23 is located at the bottom of the vertical groove 211.

[0048] Reference Figure 3 When it is necessary to replace the separating screen 3, first ensure that the external wet grinding machine is stopped. The operator loosens the first quick-connect coupling 131, the second quick-connect coupling 143, and the third quick-connect coupling 151, so that the three-way pipe 14 is separated from the first discharge pipe 13, the flushing water pipe 15 is separated from the fourth pneumatic valve 16, and the second discharge pipe 17 is separated from the second pneumatic valve 141. Then the operating system starts the servo motor 22 to drive the lead screw 25 to rotate. In the initial stage, the vertical groove 211 constrains the connecting plate 23, so that the nut 26 moves vertically upward along the lead screw 25, causing the sealing cover 12 to rise synchronously. When the connecting plate 23 moves to the position where the vertical groove 211 and the horizontal groove 212 are connected, the horizontal groove 212 is released from rotation constraint, and the connecting plate 23 then rotates into the interior of the horizontal groove 212, causing the sealing cover 12 to detach from the housing 11 and rotate around the axis of the lead screw 25. When the connecting plate 23 rotates to the end of the horizontal groove 212, the servo motor 22 stops running. At this time, the sealing cover 12 is completely moved out of the housing 11, and the operator can take out the separation screen 3 inside the housing 11.

[0049] After the operator places the new separating screen 3 inside the housing 11, the output shaft of the servo motor 22 is controlled to rotate in the opposite direction. The connecting plate 23 first rotates from the horizontal groove 212 to the inside of the vertical groove 211, driving the sealing cover 12 to rotate to the top of the housing 11. Then, the connecting plate 23 moves vertically down from the top to the bottom along the vertical groove 211, driving the sealing cover 12 to make close contact with the upper side wall of the housing 11. At this time, the sealing cover 12 and the inner wall of the housing 11 cooperate to clamp and fix the position of the separating screen 3, completing the installation of the separating screen 3. At the same time, the operator connects the first quick-change connector 131, the second quick-change connector 143 and the third quick-change connector 151, so that the three-way pipe 14 is connected to the first discharge pipe 13, the flushing water pipe 15 is connected to the fourth pneumatic valve 16, and the second discharge pipe 17 is connected to the second pneumatic valve 141, restoring the integrity of the system. Thus, the replacement of the separating screen 3 is completed. The operation and maintenance are simple and efficient.

[0050] When the servo motor 22 fails to work due to power failure or malfunction, the operator can manually operate the displacement mechanism 2 through the handwheel 24. The handwheel 24 is coaxially fixedly connected to the upper end of the lead screw 25. The upper end of the lead screw 25 rotates through the top of the assembly cylinder 21. At the same time, the output shaft of the servo motor 22 is not equipped with a braking device. Manually turning the handwheel 24 can drive the lead screw 25 to rotate, thereby adjusting the relative position of the sealing cover 12 and the housing 11 to meet the replacement requirements of the separation screen 3. This design significantly improves the fault tolerance of the displacement mechanism 2.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
