Description

Technical Field

[0001] This utility model relates to the field of cyclone mill technology, specifically a hammer cyclone mill with high cooling efficiency. Background Technology

[0002] There are two existing cooling methods for hammer mills: air cooling and liquid cooling. However, existing hammer mills only use a single cooling system to cool the grinding chamber. If the hammer mill only uses an air cooling system to cool the grinding chamber, the cooling effect is poor because air has a low specific heat capacity and heats up very quickly when it circulates at high speed inside the machine. To improve the air cooling effect, the area of ​​the two heat exchangers needs to be increased and the air duct needs to be lengthened, which will result in a larger machine size and increased energy consumption. At the same time, powdered materials can easily clog the air duct. If the hammer mill only uses a liquid cooling system to cool the grinding chamber, the cooling efficiency is low because the contact area between the liquid cooling system and the material is limited. When the material needs to be cooled to a lower temperature, the temperature of the grinding chamber needs to be set very low, which will produce condensate, causing the material to clump and block the discharge port. Utility Model Content

[0003] The purpose of this invention is to provide a hammer cyclone mill with high cooling efficiency to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a hammer cyclone mill with high cooling efficiency, comprising:

[0005] The grinding chamber has an internal working cavity for containing materials and performing crushing operations.

[0006] An air-cooling system includes air-cooling pipes that are connected to the working chamber of the grinding chamber, and the cold air inside the air-cooling pipes can flow to the working chamber.

[0007] The liquid cooling system includes a cooling coil located outside and in close contact with the grinding chamber. The cooling coil contains a flowable cooling medium for heat exchange during operation inside the grinding chamber, thereby achieving a cooling effect.

[0008] By adopting the above technical solution, the air-cooling system is located on both sides of the grinding chamber. When the air-cooling system is working, it drives the air circulation, and the temperature of the grinding chamber is carried to the outside by the flowing air, achieving the effect of initial cooling. In the liquid-cooling system, the cooling coil cools the outside of the grinding chamber and the drive shaft through the refrigerant. The liquid cooling head in the liquid-cooling system can cool the drive motor through the refrigerant. Furthermore, when the refrigerant passes through the first heat exchanger and the second heat exchanger, it can achieve heat exchange with the assistance of the air-cooling system, so that it can continuously cool the grinding chamber and the drive motor.

[0009] Preferably, the cooling coil has a spiral structure, the end of the grinding chamber has a spiral groove, the cooling coil is placed in the groove, and thermally conductive silicone grease is applied between the cooling coil and the groove. The outer ring of the cooling coil extends axially toward the side wall of the grinding chamber.

[0010] By adopting the above technical solution, the cooling coil is stably and firmly installed on the grinding chamber through the groove. Since the cooling coil has a spiral structure, it can cool the side wall of the grinding chamber and the drive shaft in all directions. Applying thermal grease between the cooling coil and the groove can also improve the heat dissipation efficiency of the grinding chamber, further cooling the grinding chamber. In addition, the thermal grease can also help fix the cooling coil and the grinding chamber.

[0011] Preferably, the inlet of the cooling coil is located at the outer ring of the spiral structure, and the outlet of the cooling coil is close to the center of the spiral structure.

[0012] By adopting the above technical solution, the high temperature generated by the friction between the rotating tool inside the grinding chamber and the inner wall of the grinding chamber causes the temperature of the outer ring inside the grinding chamber to be higher than that of the center position inside the grinding chamber. Therefore, the coolant moves from the outer ring of the cooling coil to the center position, which can better cool the grinding chamber.

[0013] Preferably, a drive shaft is mounted at the center of the grinding chamber via a bearing, and the end of the drive shaft extends outward from the grinding chamber and is connected to a drive motor via a pulley system; the outlet of the cooling coil is connected to a liquid cooling head mounted on the drive motor via a pipe, and is configured to cool the drive motor.

[0014] By adopting the above technical solution, the output end of the drive motor rotates, which drives the transmission shaft to rotate through the belt pulley system, so that the cutting tool in the grinding chamber can rotate accordingly. The refrigerant enters the liquid cooling head through the pipe, thereby removing the heat generated by the drive motor.

[0015] Preferably, the liquid cooling system further includes: a water pump group, which consists of a first water pump, a second water pump, and a third water pump; and a refrigeration unit, which consists of a first semiconductor refrigeration chip and a second semiconductor refrigeration chip. The first water pump is connected to a first heat exchanger through the first semiconductor refrigeration chip, the second water pump is connected to the second semiconductor refrigeration chip, the liquid cooling head, and the cooling coil, and the third water pump is connected to the first semiconductor refrigeration chip, the second semiconductor refrigeration chip, and the second heat exchanger.

[0016] By adopting the above technical solution, the liquid cooling system consists of three refrigerant cycles: the first refrigerant cycle is composed of a first water pump, a first thermoelectric cooler, and a first heat exchanger; the second refrigerant cycle is composed of a second water pump, a second thermoelectric cooler, a liquid cooling head, and a cooling coil; and the third refrigerant cycle is composed of a third water pump, a first thermoelectric cooler, a second thermoelectric cooler, and a second heat exchanger. This allows the refrigerant to carry away the heat generated by the grinding chamber and the drive motor and release it to the outside.

[0017] Preferably, the air-cooling system further includes a heat dissipation section, which is located on the side of the second heat exchanger away from the cooling coil, and the heat dissipation section consists of multiple cooling fans.

[0018] By adopting the above technical solution, the air-cooled pipes and heat dissipation parts in the air-cooled system cooperate with each other to exchange heat with the refrigerant in the first heat exchanger and the second heat exchanger, cool down the refrigerant in the first heat exchanger and the second heat exchanger, and cool down the grinding chamber and the drive motor.

[0019] Preferably, the hammer cyclone mill further includes a cyclone separator, which is connected to the grinding chamber via a feed pipe, allowing the material processed in the grinding chamber to enter the cyclone separator through the feed pipe.

[0020] By adopting the above technical solution, when the grinding chamber is working, after the material is processed into powder, it can enter the cyclone separator through the feed pipe, and the cyclone separator collects the powder.

[0021] Preferably, the cyclone separator includes a separator body, a buckle is installed on the top of one end of the outer surface of the separator body, a sample cup is rotatably installed on the bottom of the separator body, a filter element cover base is installed on the top of the separator body, a filter element and a filter element cover are installed on the top of the filter element cover base, and the separator body is connected to the output end of the grinding chamber through the buckle.

[0022] By adopting the above technical solution, users can remove the cyclone separator from the grinding chamber using a snap-fit ​​mechanism. The filter element in the cyclone separator can filter the material powder and collect it through a sample cup. The sample cup in this application is a standard product, and each sample cup has a lid. After the sample cup is full, it can be directly disassembled and resealed to replace it with a new sample cup. Unlike traditional cyclone mills, it is not necessary to transfer the material in the sample cup before installation and operation, which greatly improves the convenience of use for users and increases production efficiency. In addition, since the cyclone separator is detachable, it is convenient for users to clean the cyclone separator.

[0023] Preferably, it also includes a substrate with high thermal conductivity, the cooling coil is welded to the substrate, and the substrate is closely attached to the outside of the grinding chamber.

[0024] By adopting the above technical solution, the cooling coil is directly welded to the substrate, and the contact surface between the substrate and the grinding chamber is large, which improves the cooling effect of the grinding chamber. At the same time, the components are modularized, which facilitates production and processing.

[0025] Preferably, the hammer cyclone mill further includes: a main unit, which has an overall box-type structure, wherein the grinding chamber, air-cooling system and liquid-cooling system are all installed inside the main unit, and a PID controller, a feeding section and a cyclone separator are provided outside the main unit.

[0026] By adopting the above technical solution, the user adds materials into the grinding chamber through the feeding section, while the air-cooling system and liquid-cooling system can cool the grinding chamber. Furthermore, the user can adjust the power of the grinding chamber, air-cooling system, and liquid-cooling system through the PID controller, thereby achieving intelligent control of the grinding chamber's operating temperature.

[0027] Compared with the prior art, the beneficial effects of this utility model are:

[0028] 1. This high-efficiency hammer cyclone mill, through the cooperation of the water pump group, the first heat exchanger, the second heat exchanger, the refrigeration unit and the cooling pipes, can liquid cool the heat-generating components such as the grinding chamber, bearing housing and cutting tools. The coolant flowing out of the grinding chamber flows through the motor liquid cooling head to cool the motor. Then the coolant passes through the water pump group to circulate and cool the heat-generating components.

[0029] 2. This high-efficiency hammer cyclone mill utilizes the cooperation between the second heat exchanger and the heat dissipation unit to achieve air cooling. The heat in the coolant is carried away by the ambient air, achieving continuous heat dissipation for the semiconductor cooling chip. Furthermore, the heat dissipation unit can blow the heat inside the device to the outside, further cooling the electronic components inside the device.

[0030] 3. This high-efficiency hammer cyclone mill, through the combination of air cooling and liquid cooling, can provide all-round cooling during the material crushing process, and ensure that the temperature difference between the grinding chamber and the environment is not too large, preventing condensation from forming on the inner wall of the grinding chamber. In addition, the combination of air cooling and liquid cooling does not require increasing the area of ​​the two heat exchangers or lengthening the air duct, effectively improving air cooling efficiency while reducing energy consumption, avoiding the consequences of material powder clogging the air duct, enabling the device to achieve continuous non-heating crushing, improving working efficiency, and ensuring the accuracy of sample index test results.

[0031] 4. This high-efficiency hammer cyclone mill uses quick-connect couplings for the cyclone separator, main unit, separator cylinder, and filter cover, making disassembly and cleaning of the cyclone separator convenient. Furthermore, the sample cup is a standard product with a lid and is connected to the cyclone separator by a thread, making it easy to install, disassemble, and store, thus improving work efficiency.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0046] Please see Figure 1-9 One embodiment of this utility model is a hammer cyclone mill with high cooling efficiency, comprising:

[0047] The grinding chamber 13 has a working cavity inside which is used to contain materials for crushing.

[0048] The air-cooling system includes an air-cooling pipe 6, which is connected to the working chamber of the grinding chamber 13, and the cold air inside the air-cooling pipe 6 can flow to the working chamber.

[0049] The liquid cooling system includes a cooling coil 14, which is located outside the grinding chamber 13 and is in close contact with the grinding chamber 13. The cooling coil 14 contains a flowable cooling medium for heat exchange when working inside the grinding chamber 13, thereby achieving a cooling effect.

[0050] The air-cooling system is located on both sides of the grinding chamber 13. When the air-cooling system is working, it drives the air circulation, and the temperature of the grinding chamber 13 is carried to the outside by the flowing air, achieving the effect of initial cooling. In the liquid cooling system, the cooling coil 14 cools the outside of the grinding chamber 13 and the drive shaft through the refrigerant. The liquid cooling head 9 in the liquid cooling system can cool the drive motor 8 through the refrigerant. Furthermore, when the refrigerant passes through the first heat exchanger 7 and the second heat exchanger 10, it can achieve heat exchange with the assistance of the air-cooling system, so that it can continuously cool the grinding chamber 13 and the drive motor 8.

[0051] In this embodiment, the cooling coil 14 has a spiral structure, and the end of the grinding chamber 13 has a spiral groove. The cooling coil 14 is placed in the groove, and thermal grease is applied between the cooling coil 14 and the groove. The outer ring of the cooling coil 14 extends axially towards the side wall of the grinding chamber 13. The cooling coil 14 is stably and firmly installed on the grinding chamber 13 through the groove. Since the cooling coil 14 has a spiral structure, it can cool the side wall of the grinding chamber 13 and the drive shaft in all directions. The thermal grease applied between the cooling coil 14 and the groove can also improve the heat dissipation efficiency of the grinding chamber 13, further cooling the grinding chamber 13. In addition, the thermal grease can also help fix the cooling coil 14 and the grinding chamber 13.

[0052] In this embodiment, the inlet of the cooling coil 14 is located at the outer ring of the spiral structure, and the outlet of the cooling coil 14 is close to the center of the spiral structure. Due to the high temperature generated by the friction between the rotating tool inside the grinding chamber 13 and the inner wall of the grinding chamber 13, the temperature of the outer ring inside the grinding chamber 13 is higher than that of the center inside the grinding chamber 13. Therefore, the refrigerant moves from the outer ring of the cooling coil 14 to the center, which can better cool the grinding chamber 13.

[0053] In this embodiment, a drive shaft is mounted on the center of the grinding chamber 13 via a bearing. The end of the drive shaft extends outward from the grinding chamber 13 and is connected to the drive motor 8 via a pulley system. The outlet of the cooling coil 14 is connected to the liquid cooling head 9 mounted on the drive motor 8 via a pipe. The cooling coil 9 is used to cool the drive motor 8. The output end of the drive motor 8 rotates, which drives the drive shaft to rotate via the pulley system, so that the cutting tool in the grinding chamber 13 can rotate accordingly. The coolant enters the liquid cooling head 9 through the pipe, thereby carrying away the heat generated by the drive motor 8.

[0054] In this embodiment, the liquid cooling system further includes: a water pump assembly 5, which consists of a first water pump 51, a second water pump 52, and a third water pump 53; and a cooling section 12, which consists of a first thermoelectric cooler 121 and a second thermoelectric cooler 122. The first water pump 51 is connected to the first heat exchanger 7 via the first thermoelectric cooler 121, the second water pump 52 is connected to the second thermoelectric cooler 122, the liquid cooling head 9, and the cooling coil 14, and the third water pump 53 is connected to the first thermoelectric cooler 121 and the second thermoelectric cooler 122. 22 is connected to the second heat exchanger 10. The liquid cooling system consists of three refrigerant cycles: the first water pump 51, the first semiconductor refrigeration chip 121 and the first heat exchanger 7 form the first refrigerant cycle; the second water pump 52, the second semiconductor refrigeration chip 122, the liquid cooling head 9 and the cooling coil 14 form the second refrigerant cycle; and the third water pump 53, the first semiconductor refrigeration chip 121, the second semiconductor refrigeration chip 122 and the second heat exchanger 10 form the third refrigerant cycle, so that the refrigerant can carry away the heat generated by the grinding chamber 13 and the drive motor 8 and release it to the outside.

[0055] In this embodiment, the air-cooling system also includes a heat dissipation section 11, which is located on the side of the second heat exchanger 10 away from the cooling coil 14. The heat dissipation section 11 is composed of multiple cooling fans. The air-cooling pipe 6 and the heat dissipation section 11 cooperate with each other in the air-cooling system to exchange heat with the refrigerant in the first heat exchanger 7 and the second heat exchanger 10, cool down the refrigerant in the first heat exchanger 7 and the second heat exchanger 10, and cool down the grinding chamber 13 and the drive motor 8.

[0056] In this embodiment, the hammer cyclone mill also includes a cyclone separator 4, which is connected to the grinding chamber 13 through a feed pipe. The material processed by the grinding chamber 13 can enter the cyclone separator 4 through the feed pipe. When the grinding chamber 13 is working, after the material is processed into powder, it can enter the cyclone separator 4 through the feed pipe, and the cyclone separator 4 collects the powder.

[0057] In this embodiment, the cyclone separator 4 includes a separator body 41. A buckle 42 is installed on the top of one end of the outer surface of the separator body 41. A sample cup 43 is rotatably installed on the bottom of the separator body 41. A filter element cover base 44 is installed on the top of the separator body 41. A filter element 45 and a filter element cover 46 are installed on the top of the filter element cover base 44. The separator body 41 is connected to the output end of the grinding chamber 13 through the buckle 42. The user can remove the cyclone separator 4 from the grinding chamber 13 through the buckle 42. The filter element 45 in the cyclone separator 4... 5. It can filter material powder and collect it through sample cup 43. The sample cup 43 in this application is a standard product. Each sample cup 43 is equipped with a lid. After the sample cup 43 is full, it can be directly disassembled and sealed to replace the new sample cup 43. Unlike traditional cyclone mills, it is not necessary to transfer the material in the sample cup 43 before installation and operation. This greatly improves the convenience of use for users and increases production efficiency. At the same time, since the cyclone separator 4 is detachable, it is convenient for users to clean the cyclone separator 4.

[0058] In this embodiment, the hammer cyclone mill also includes: a main unit 1, which has an overall box-type structure. The grinding chamber 13, the air-cooling system, and the liquid-cooling system are all installed inside the main unit 1. The main unit 1 is equipped with a PID controller 2, a feeding section 3, and a cyclone separator 4. The user adds materials into the grinding chamber 13 through the feeding section 3. The air-cooling system and the liquid-cooling system can cool down the grinding chamber 13. The user can also adjust the power of the grinding chamber 13, the air-cooling system, and the liquid-cooling system through the PID controller 2, thereby realizing intelligent control of the working temperature of the grinding chamber 13.

[0059] Please see Figure 10-12 Another embodiment of this utility model includes a high thermal conductivity substrate. The cooling coil 14 is welded to the substrate, which is tightly fitted to the outside of the grinding chamber 13. The cooling coil 14 is directly welded to the substrate, and the contact surface between the substrate and the grinding chamber 13 is large. One side of the grinding chamber 13 is completely covered by the substrate. Due to the high thermal conductivity of the substrate, the heat generated by the grinding chamber 13 is transferred to the outside through the substrate, improving the cooling effect of the grinding chamber 13. Simultaneously, the components are modularized, facilitating production and processing. Both embodiments effectively improve the heat dissipation efficiency of the grinding chamber, and this application does not impose any limitations.

[0060] Working principle: The user adds material into the grinding chamber 13 through the feeding section 3, and then sets the temperature through the PID controller 2. When the grinding chamber 13 is working, the air cooling system and the liquid cooling system are started. The air cooling system and the liquid cooling system can simultaneously cool the grinding chamber 13 and the drive motor 8. The air cooling system can also exchange heat and cool the refrigerant in the first heat exchanger 7 and the second heat exchanger 10 in the liquid cooling system. This allows the refrigerant to circulate in the liquid cooling system and continuously cool the grinding chamber 13 and the drive motor 8, preventing the temperature inside the grinding chamber 13 from becoming too high.
