Description

Technical Field

[0001] This utility model relates to the field of grinding equipment technology, specifically to a nano-grinding device with a cooling mechanism. Background Technology

[0002] The nano-grinding mill is a new type of grinding machine. It uses imported high-precision double-end mechanical seals and can utilize minimal grinding media. Material enters the grinding chamber from the top via a feed pump. During the intense grinding process, the pins and stator continuously and violently impact the grinding media, which in turn acts on the material, resulting in thorough grinding. It has wide applications in fields such as carbon nanotubes, nanomaterials, pigments, nano-coatings, and inks.

[0003] Most nano-grinding equipment currently on the market is similar in structure. It uses a drive motor to rotate a rod shaft, which agitates the abrasive and material in the grinding chamber. Friction and compression occur between the abrasive and material, grinding the material. The ground material is then discharged through the outlet after being screened by a sieve. However, there are some functional shortcomings in actual use, which have room for improvement. For example, during the grinding process, a large amount of friction generates heat, causing the material temperature to rise rapidly. This is a drawback when grinding temperature-sensitive materials, as high temperatures can easily affect the properties of the material, requiring cooling treatment. The equipment does not have a function to easily cool the material.

[0004] Now, a novel nano-grinding device with a cooling mechanism is proposed to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a nano-grinding device with a cooling mechanism to solve the problem mentioned in the background art of not having the function of easily cooling materials.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a nano-grinding device with a cooling mechanism, comprising a support box, a motor housing fixedly connected to the left side of the top of the support box, a controller provided at the front end of the motor housing, a drive motor installed on the right side inside the motor housing, a rotating rod pin movably connected to the right side of the motor housing, a grinding sleeve fixedly connected to the right side of the grinding sleeve, a screen housing fixedly connected to the right side of the grinding sleeve, a separation screen fixedly connected inside the screen housing, a discharge port welded to the bottom of the right side of the screen housing, and a cooling component for rapidly cooling materials provided at the bottom of the support box.

[0007] The cooling assembly includes an inlet tank, which is fixedly connected to the right side of the bottom of the inner side of the support housing. An outlet tank is located behind the inlet tank. Multiple sets of conductive pipes are welded between one end of the inlet tank and the outlet tank. A cooling fan is installed on the right side of the conductive pipes. A first circulation pump is installed at the top of the inlet tank. An outer shell is fitted over the grinding sleeve. A copper coil is horizontally arranged inside the outer shell. A return port is fixedly connected to the left side of the top of the copper coil. An inlet port is fixedly connected to the right side of the top of the copper coil. A return pipe is movably connected between the first circulation pump and the return port. A delivery pipe is movably connected between the outlet tank and the inlet port.

[0008] As a further technical solution of this utility model, the liquid inlet tank, the liquid outlet tank, and the conductive pipe are internally connected, and multiple sets of aluminum fins are welded between each pair of the conductive pipes.

[0009] As a further technical solution of this utility model, the inner ring of the copper coil is in contact with the outer wall of the grinding sleeve, and there is a distance between the outer ring of the copper coil and the inner wall of the outer casing.

[0010] As a further technical solution of this utility model, the internal connections of the reflux interface, copper coil, and liquid inlet interface are interconnected, and the right side of the cooling fan passes through the right side of the support box and extends to the outside.

[0011] As a further technical solution of this utility model, steel tubes are fixedly connected to the four corners of the bottom of the bearing box, a miniature electric cylinder is installed at the top of the inside of the steel tube, and a support block is provided at the bottom of the inside of the steel tube.

[0012] As a further technical solution of this utility model, the top end of the support block is connected to the output end of the micro electric cylinder, and the support block can slide up and down along the inside of the steel tube.

[0013] As a further technical solution of this utility model, a solenoid valve is installed on the right side of the discharge port, a circulation interface is welded to the top of the discharge port, a backwash interface is welded to the top of the right side of the screen cover, and a second circulation pump is installed between the circulation interface and the backwash interface.

[0014] As a further technical solution of this utility model, the discharge port, circulation interface, and backwashing interface are internally connected, and the solenoid valve and the second circulation pump are electrically connected.

[0015] Compared with the prior art, the beneficial effects of this utility model are: the nano-grinding equipment with a cooling mechanism not only realizes the function of facilitating material cooling, but also realizes the function of supporting and preventing shaking, and also realizes the function of preventing screen blockage;

[0016] (1) By setting up an inlet tank, an outlet tank, a connecting pipe, a cooling fan, a first circulation pump, a return pipe, a delivery pipe, a return interface, an outer shell, a copper coil, and an inlet interface, when in use, the material and abrasive are injected through the interface at the top of the grinding sleeve, and the drive motor is started. The drive motor drives the rotating rod pin to rotate continuously. The rotating rod pin stirs the material and abrasive. Under the pressure of the abrasive, the material is quickly crushed. As the grinding proceeds, the temperature inside the grinding sleeve begins to rise. The first circulation pump and the cooling fan start synchronously. Driven by the first circulation pump, the cold water in the inlet tank and the outlet tank forms a circulation. It forms a circulation along the path of the delivery pipe, the inlet interface, the copper coil, the return interface, and the return pipe. The cold water flows between the inlet tank and the outlet tank through the connecting pipe. With the blowing of the cooling fan, the fins between the two connecting pipes can quickly carry away the heat, keeping the cold water at a low temperature. The copper coil reduces the surface temperature of the grinding sleeve, thereby reducing the temperature of the material, and realizing the function of facilitating material cooling.

[0017] (2) By setting up steel cylinders, micro electric cylinders and support blocks, when in use, the four corners at the bottom of the load box are supported by steel cylinders. When the equipment shakes, find the suspended corner, start the micro electric cylinder at the corresponding position, and the micro electric cylinder pushes the support block down and presses it against the ground. Repeat the adjustment until the equipment is stable and does not shake, thus realizing the function of supporting and preventing shaking.

[0018] (3) By setting up a screen cover, a separating screen, a discharge port, a solenoid valve, a circulation interface, a second circulation pump and a backwash interface, when in use, as the material is being ground, the solenoid valve opens, the separating screen in the screen cover blocks the abrasive and filters out the material. When the separating screen is blocked, the solenoid valve is closed and the second circulation pump is started. The second circulation pump draws out the material in the discharge port and pumps it back into the screen cover through the backwash interface, which flushes the separating screen and removes the blockage, thus achieving the function of preventing screen blockage.

Detailed Implementation

[0025] 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.

[0026] Example 1: Please refer to Figure 1-5 A nano-grinding device with a cooling mechanism includes a support box 1, a motor housing 2 fixedly connected to the top left side of the support box 1, a controller 3 set at the front end of the motor housing 2, a drive motor 4 installed inside the right side of the motor housing 2, a rotating rod pin 5 movably connected to the right side of the motor housing 2, a grinding sleeve 6 fixedly connected to the right side of the grinding sleeve 6, a screen cover 21 fixedly connected to the right side of the grinding sleeve 6, a separation screen 22 fixedly connected inside the screen cover 21, a discharge port 23 welded to the bottom right side of the screen cover 21, and a cooling component that can quickly cool materials set at the bottom end inside the support box 1.

[0027] Please see Figure 1-5 A nano-grinding device with a cooling mechanism also includes a cooling assembly, which includes an inlet tank 7, which is fixedly connected to the right side of the bottom of the support box 1. An outlet tank 8 is provided behind the inlet tank 7. Multiple sets of conductive pipes 9 are welded between one end of the inlet tank 7 and the outlet tank 8. A cooling fan 10 is installed on the right side of the conductive pipes 9. A first circulation pump 11 is installed at the top of the inlet tank 7. An outer shell 15 is fitted over the outside of the grinding sleeve 6. A copper coil 16 is arranged horizontally inside the outer shell 15. A return port 14 is fixedly connected to the left side of the top of the copper coil 16. An inlet port 17 is fixedly connected to the right side of the top of the copper coil 16. A return pipe 12 is movably connected between the first circulation pump 11 and the return port 14. A delivery pipe 13 is movably connected between the outlet tank 8 and the inlet port 17.

[0028] The liquid inlet tank 7, liquid outlet tank 8, and guide pipe 9 are internally connected. Multiple sets of aluminum fins are welded between each pair of guide pipes 9. The inner ring of the copper coil 16 is in contact with the outer wall of the grinding sleeve 6. There is a distance between the outer ring of the copper coil 16 and the inner wall of the outer casing 15. The return port 14, copper coil 16, and liquid inlet port 17 are internally connected. The right side of the cooling fan 10 passes through the right side of the bearing box 1 and extends to the outside, which facilitates the cooling of materials.

[0029] Specifically, such as Figure 1 , Figure 2 and Figure 4 As shown, the first circulation pump 11 and the cooling fan 10 start synchronously. Driven by the first circulation pump 11, the cold water in the inlet tank 7 and the outlet tank 8 forms a circulation, which is formed along the path of the liquid delivery pipe 13, the liquid inlet interface 17, the copper coil 16, the return interface 14, and the return pipe 12. The cold water flows between the inlet tank 7 and the outlet tank 8 through the conductive pipe 9. With the blowing of the cooling fan 10, the fins between the two pairs of conductive pipes 9 can quickly remove heat, keeping the cold water at a low temperature. The copper coil 16 reduces the surface temperature of the grinding sleeve 6, thereby reducing the material temperature.

[0030] Example 2: Steel tubes 18 are fixedly connected to the four corners of the bottom of the bearing box 1. A miniature electric cylinder 19 is installed at the top of the inside of the steel tube 18. A support block 20 is provided at the bottom of the inside of the steel tube 18. The top of the support block 20 is connected to the output end of the miniature electric cylinder 19. The support block 20 can slide up and down along the inside of the steel tube 18 to facilitate the adjustment of the equipment balance.

[0031] Specifically, such as Figure 1 and Figure 3 As shown, start the miniature electric cylinder 19. The miniature electric cylinder 19 pushes the support block 20 down and presses it against the ground. Repeat the adjustment until the equipment is stable and does not shake.

[0032] Example 3: A solenoid valve 24 is installed on the right side of the discharge port 23, a circulation interface 25 is welded to the top of the discharge port 23, a backwash interface 27 is welded to the top of the right side of the screen cover 21, a second circulation pump 26 is installed between the circulation interface 25 and the backwash interface 27, the discharge port 23, the circulation interface 25 and the backwash interface 27 are internally connected, the solenoid valve 24 and the second circulation pump 26 are electrically connected, and backwashing is used to prevent screen blockage.

[0033] Specifically, such as Figure 1 and Figure 5 As shown, the solenoid valve 24 is closed and the second circulation pump 26 is started. The second circulation pump 26 draws out the material in the discharge port 23 and pumps it back into the screen cover 21 through the backwash port 27, which flushes the separation screen 22 and causes the blockage to fall off.

[0034] Working Principle: In use, the material and abrasive are first injected through the interface at the top of the grinding sleeve 6. Then, the drive motor 4 is started, which drives the rotating rod pin 5 to rotate continuously. The rotating rod pin 5 agitates the material and abrasive. Under the pressure of the abrasive, the material is quickly crushed. As grinding proceeds, the internal temperature of the grinding sleeve 6 begins to rise. The first circulation pump 11 and the cooling fan 10 start synchronously. Driven by the first circulation pump 11, the cold water in the inlet tank 7 and outlet tank 8 forms a circulation, circulating along the path of the delivery pipe 13, the inlet interface 17, the copper coil 16, the return interface 14, and the return pipe 12. The cold water flows between the inlet tank 7 and the outlet tank 8 through the conductive pipe 9. With the blowing of the cooling fan 10, the fins between the two pairs of conductive pipes 9 can quickly remove heat, keeping the cold water at a low temperature. The copper coil 16 lowers the surface temperature of the grinding sleeve 6, thereby lowering the temperature of the material. The four corners at the bottom of the support box 1 are supported by steel tubes 18. When the equipment shakes, find the corner that is suspended and start the corresponding micro electric cylinder 19. The micro electric cylinder 19 pushes the support block 20 down and presses it against the ground. Repeat the adjustment until the equipment is stable and does not shake. As the material is being ground, the solenoid valve 24 opens, and the separation screen 22 in the screen cover 21 blocks the abrasive and filters out the material. When the separation screen 22 becomes clogged, the solenoid valve 24 is closed and the second circulation pump 26 is started. The second circulation pump 26 draws out the material in the outlet 23 and pumps it back into the screen cover 21 through the backwash interface 27, which flushes the separation screen 22 and dislodges the blockage.

[0035] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
