Description

Technical Field

[0001] The utility model relates to the technical field of pulverizers, in particular to a claw-type pulverizer. Background Art

[0002] As a key piece of equipment in the field of pulverization technology, the development of claw mills can be traced back to the gradual maturity and innovation of early mechanical pulverization technology. With the advancement of industrialization, claw mills, with their efficient pulverization capacity and wide applicability, have gradually gained a foothold in various fields, including food, chemicals, and agriculture.

[0003] However, despite significant advancements, existing claw-type grinders still face significant challenges. During extended periods of continuous operation, mechanical friction in claw-type grinders generates significant heat, which easily accumulates within the grinder, causing the equipment to overheat. This high temperature not only exacerbates mechanical wear and shortens the equipment's lifespan, but also causes some powder to adhere to the grinder's pulverizing mechanism during the pulverization process, making it difficult to remove. This, in turn, affects the equipment's pulverization efficiency and the uniformity of the material's fineness.

[0004] More seriously, high temperatures can adversely affect material properties. This is especially true for temperature-sensitive materials, such as food or pharmaceutical ingredients containing bioactive ingredients. High temperatures can trigger chemical changes, leading to nutrient loss, color and odor changes, and even deterioration and failure. Furthermore, excessive heat can cause equipment failures, such as motor overheating and bearing damage, leading to production interruptions and even fire hazards, posing a serious threat to production safety.

[0035] The embodiment of the present application provides a claw type crusher, such as Figure 1 As shown, the claw crusher includes a frame 100, a crushing assembly and a cooling assembly.

[0036] For example, the frame 100 is fixed to the ground by welding, clamping, or bolting. Fixing the frame 100 to the ground by welding, clamping, or bolting enhances the stability of the equipment, reduces vibration and noise during operation, and provides a more stable working environment for the crushing operation.

[0037] Exemplarily, a flexible pad is further provided between the rack 100 and the ground, and the provided flexible pad can further reduce vibration.

[0038] like Figure 1 As shown, a mounting shell 110 is provided on the frame 100; Figure 3 and Figure 4 As shown, the mounting housing 110 has a cooling chamber 120 and a working chamber 130 that are independent of each other.

[0039] The crushing assembly is arranged in the working chamber 130 for crushing materials. By arranging the crushing assembly in the working chamber 130, it is possible to focus on the crushing operation of the materials and reduce external interference, thereby improving the crushing efficiency and production capacity.

[0040] The heat generated by the pulverizing assembly can be transferred to the cooling chamber 120. The cooling assembly is used to cool the cooling chamber 120, thereby cooling the pulverizing assembly located within the working chamber 130. The heat generated during the pulverizing process can be transferred to the adjacent cooling chamber 120, allowing the heat to be quickly processed by the cooling assembly, effectively preventing performance degradation or damage to the pulverizing assembly due to overheating and extending the service life of the equipment.

[0041] The high-temperature crushing assembly is arranged adjacent to the cooling chamber 120, and the temperature is promptly reduced by the cooling assembly, thereby reducing the safety hazards caused by high temperature, such as the risk of fire, burns and other accidents.

[0042] In this embodiment, the cooling method of the cooling component includes but is not limited to air cooling, water cooling, etc.

[0043] like Figure 1 and Figure 2 As shown, in one embodiment, the cooling assembly further includes a first cooling tank 200 and a first circulation pump.

[0044] The first cooling box 200 stores a cooling medium, and the first circulating pump drives the cooling medium to circulate between the cooling chamber 120 and the first cooling box 200. For example, the first circulating pump is connected to the cooling chamber 120 through a pipeline, and the first circulating pump is connected to the first cooling box 200 through a pipeline.

[0045] Exemplarily, the cooling medium absorbs heat in the cooling chamber 120 and is cooled in the first cooling box 200 .

[0046] Illustratively, the first circulating pump is fixedly mounted on the first cooling box 200, the ground and / or the rack 100 by welding, clamping, bolting, etc. Illustratively, the manufacturing material of the first cooling box 200 includes but is not limited to: plastic, stainless steel or aluminum.

[0047] Exemplarily, the cooling medium includes but is not limited to water, air, oil, salt water, etc.

[0048] Exemplarily, a fan is further provided on the first cooling box 200 , and the fan blows air to the cooling medium in the first cooling box 200 to promote evaporation of water in the cooling medium, so as to cool the cooling medium in the first cooling box 200 .

[0049] The first circulating pump drives the cooling medium to circulate between the cooling chamber 120 and the first cooling box 200, which can continuously remove the heat generated by the crushing assembly during operation, ensure that the crushing assembly operates at a lower temperature, improve the heat dissipation efficiency, and thus extend the service life of the crushing assembly.

[0050] Since the cooling medium can circulate continuously, it can absorb and dissipate heat more evenly, making the temperature in the cooling chamber 120 more stable, which is conducive to maintaining stable operation and efficient work of the pulverizing assembly.

[0051] The first cooling box 200 and the first circulating pump are designed to be relatively independent, which is convenient for maintenance and repair. At the same time, since the cooling medium circulates in a closed system, system failures caused by external contamination are reduced.

[0052] In one embodiment, the cooling assembly includes a second cooling box, a second circulating pump, and cooling pipes. The second cooling box stores a cooling medium; the second circulating pump is connected to the second cooling box; and the cooling pipes are connected to the second circulating pump, with portions of the cooling pipes disposed on the inner wall of the cooling chamber 120. The second circulating pump drives the cooling medium to circulate within the second cooling box and the cooling pipes to cool the mounting housing 110.

[0053] By placing some cooling pipes directly on the inner wall of the cooling chamber 120, the cooling medium can directly contact the surface of the mounting shell 110, thereby achieving direct cooling of the mounting shell 110. This method is more efficient than indirect cooling and can quickly reduce the temperature of the mounting shell 110, thereby improving its operational stability and lifespan.

[0054] The arrangement of the cooling pipes on the inner wall of the cooling chamber 120 can be optimized based on actual conditions to ensure that the cooling medium can flow evenly through all parts of the mounting housing 110, thereby achieving uniform temperature distribution. This helps reduce the risk of thermal stress concentration and damage caused by local overheating.

[0055] The second circulating pump, connected to the second cooling tank, delivers the cooling medium to the cooling pipes through pipes, driving their circulation. This closed-loop circulation system reduces cooling medium consumption and waste, while also preventing external contamination from affecting the system and improving the reliability and stability of the cooling components.

[0056] The cooling assembly can be adjusted and optimized according to different cooling requirements and working environments. For example, different cooling requirements can be met by changing the layout of the cooling pipes, increasing or decreasing the number of cooling pipes, adjusting the type and temperature of the cooling medium, etc.

[0057] Exemplarily, the second circulating pump is fixedly mounted on the second cooling box, the ground and / or the rack 100 by welding, clamping, bolting, or the like.

[0058] Illustratively, the manufacturing material of the second cooling box includes but is not limited to: plastic, stainless steel or aluminum.

[0059] In one embodiment, the cooling chamber 120 is provided with an air inlet and an air outlet; the cooling assembly includes an air inlet unit, which is provided on the mounting shell 110 and located at the air inlet, and the air inlet unit sends external air into the cooling chamber 120 through the air inlet.

[0060] Exemplarily, the air inlet unit includes fan blades and a motor. The fan blades are fixedly mounted on the motor output shaft. The motor is fixedly arranged on the inner wall of the air inlet. The rotation of the motor drives the fan blades to rotate. The rotation of the fan blades promotes the entry of low-temperature air from the outside into the cooling chamber 120.

[0061] The setting of the air inlet unit allows external cold air to enter the cooling chamber 120 directly and efficiently, filling the cooling chamber 120 with low-temperature air, which can reduce the temperature in the cooling chamber 120 and the working chamber 130 more quickly and protect the equipment from high temperature damage.

[0062] The air inlet unit is provided to improve the air flow in the cooling chamber 120 , reduce the temperature in the cooling chamber 120 , improve the heat dissipation efficiency of the cooling chamber 120 , and improve the heat exchange efficiency between the cooling chamber 120 and the working chamber 130 .

[0063] Compared with complex cooling systems (such as liquid cooling systems), this air cooling method based on natural convection is simpler in structure, reduces the number and complexity of components, and reduces manufacturing costs and maintenance difficulties.

[0064] In one embodiment, the cooling assembly further includes an exhaust unit, which is disposed on the mounting shell 110 and located at an air outlet to exhaust the air in the cooling chamber 120 to the outside.

[0065] Exemplarily, the exhaust unit includes fan blades and a motor. The fan blades are fixedly mounted on the output shaft of the motor. The motor is fixedly arranged on the inner wall of the air outlet. The rotation of the motor drives the fan blades to rotate. The rotation of the fan blades promotes the high-temperature air in the cooling chamber 120 to enter the outside world.

[0066] The exhaust unit can actively exhaust the hot air in the cooling chamber 120 to form a continuous airflow cycle. This active exhaust combined with the cold air introduced by the air intake unit can more effectively reduce the temperature in the cooling chamber 120 and improve the heat dissipation efficiency.

[0067] Expelling hot air through the exhaust unit prevents accumulation of hot air within the cooling chamber 120, thereby optimizing temperature distribution. This helps reduce the risk of thermal stress concentration and thermal expansion damage caused by local overheating, improving the overall performance and reliability of the equipment and extending its service life.

[0068] The provision of the exhaust unit can reduce the possibility of hot air flowing back into the cooling chamber 120. When the hot air is discharged in time, new cold air can enter the cooling chamber 120 more quickly and exchange heat with the internal heat source, thereby maintaining a lower internal temperature.

[0069] The exhaust unit allows the cooling components to better adapt to different working environments and conditions. Whether in high-temperature environments or where rapid heat dissipation is required, the exhaust unit can provide effective heat dissipation support.

[0070] In some embodiments, the claw grinder further includes a control component that can control the start and stop of the cooling component according to the temperature of the working chamber 130. Exemplarily, the control component includes a temperature sensor and a controller, and the controller is electrically connected to the temperature sensor and the cooling component (e.g., the first circulation pump, the second circulation pump, the air intake unit, the exhaust unit, etc.). The temperature sensor is disposed on the inner wall of the working chamber 130. The temperature sensor is used to detect the temperature of the working chamber 130 and send the detection result to the controller. The controller controls the start and stop of the cooling component based on the detection result. When the temperature is detected to be greater than the first preset temperature, the controller controls the cooling component to drive to cool the working chamber 130.

[0071] In other embodiments, temperature sensors are disposed on the inner walls of the working chamber 130 and the cooling chamber 120. The temperature sensors are used to detect the temperatures of the working chamber 130 and the cooling chamber 120 and transmit the detection results to a controller. The controller controls the start and stop of the cooling assembly based on the detection results. When the temperature of the working chamber 130 is detected to be greater than a first preset temperature, the controller controls the cooling assembly to drive to cool the working chamber 130. When the temperature of the cooling chamber 120 is detected to be greater than a second preset temperature, the controller controls the cooling assembly to increase power to further cool the working chamber 130. Exemplarily, the first preset temperature and the second preset temperature are discrete values or ranges. Exemplarily, the first preset temperature is less than or equal to the second preset temperature.

[0072] like Figure 3 and Figure 4 As shown, in one embodiment, the pulverizing assembly includes a rotating disk 310, which is rotatably mounted within the working chamber 130. A first toothed claw 350 is disposed on the rotating disk 310. The rotation of the rotating disk 310 drives the first toothed claw 350 to pulverize the material. For example, the first toothed claw 350 on the rotating disk 310 continuously contacts the material as the rotating disk 310 rotates, pulverizing the material through physical impact and shearing. This design effectively pulverizes the material, improving processing speed and efficiency.

[0073] For example, in some embodiments, the rotating disk 310 and the first tooth claw 350 are generally designed to be detachable or easily replaceable, which facilitates cleaning, inspection, and replacement of worn parts during equipment maintenance. This helps to extend the service life of the equipment and reduce maintenance costs.

[0074] like Figure 3 and Figure 4 As shown, in one embodiment, the shredding assembly further includes a fixed disk 320 , which is disposed on the mounting shell 110 .

[0075] The fixed disk 320 is disposed opposite the rotating disk 310, and a second tooth claw 360 is provided on the fixed disk 320. When the rotating disk 310 rotates, the first tooth claw 350 and the second tooth claw 360 form relative motion. This relative motion can more effectively shear, impact, and grind the material, thereby enhancing the pulverization effect and making the material finer and more uniform.

[0076] The interaction between the first claw 350 and the second claw 360 increases the contact points and the force during the crushing process, so that the material can be crushed to the desired particle size in a shorter time. This helps to improve the crushing efficiency and reduce the processing time.

[0077] like Figure 4As shown, in one embodiment, the first teeth pawl 350 is fixedly disposed on a side of the rotating disk 310 near the fixed disk 320, and a plurality of first teeth pawls 350 are provided. For example, six first teeth pawls 350 are provided, and the six first teeth pawls 350 are evenly arranged on the rotating disk 310 around the rotation center of the rotating disk 310. In other embodiments, ten first teeth pawls 350 are provided, and the ten first teeth pawls 350 are evenly arranged on the rotating disk 310 around the rotation center of the rotating disk 310. In other embodiments, twenty first teeth claws 350 are provided, and the twenty first teeth claws 350 are divided into two groups. One group of first teeth claws 350 is provided on the rotating disk 310 around a first circular trajectory, and the other group of first teeth claws 350 is provided on the rotating disk 310 around a second circular trajectory. The first circular trajectory and the second circumferential trajectory are coaxially arranged with the rotation axis of the rotating disk 310, and the diameter of the first circumferential trajectory is greater than the diameter of the second circumferential trajectory. Of course, the first teeth claws 350 can also be provided in other numbers, or can be divided into three groups, four groups, etc., which will not be repeated here.

[0078] Exemplarily, the first claw 350 is fixed on the rotating disk 310 by welding, clamping, bolting or integral molding.

[0079] like Figure 4 As shown, in one embodiment, a plurality of second teeth claws 360 are provided on the fixed disk 320. Exemplarily, six second teeth claws 360 are provided, and the six second teeth claws 360 are evenly arranged on the fixed disk 320 around the axis of the rotating disk 310. In other embodiments, ten second teeth claws 360 are provided, and the ten second teeth claws 360 are evenly arranged on the fixed disk 320 around the axis of the fixed disk 320. In other embodiments, twenty second teeth claws 360 are provided, and the twenty second teeth claws 360 are divided into two groups: one group of second teeth claws 360 is provided on the fixed disk 320 around a third circumferential trajectory, and the other group of second teeth claws 360 is provided on the fixed disk 320 around a fourth circumferential trajectory. The third and fourth circumferential trajectories are coaxial with the axis of the fixed disk 320, and the diameter of the third circumferential trajectory is larger than the diameter of the fourth circumferential trajectory. Of course, the second teeth claws 360 can also be provided in other numbers, or can be divided into three or four groups, etc., which will not be further described here.

[0080] For example, in some embodiments, the diameter of the first circular trajectory is greater than the diameter of the third circular trajectory, the diameter of the third circular trajectory is greater than the diameter of the second circular trajectory, and the diameter of the second circular trajectory is greater than the diameter of the fourth circular trajectory.

[0081] Exemplarily, the second claw 360 is fixed on the fixing plate 320 by welding, clamping, bolt connection or integral molding.

[0082] By adjusting parameters such as the rotational speed of the rotating disk 310 and the fixed disk 320, as well as the shape and number of the teeth, the crushing requirements for different materials can be met. This makes the equipment more adaptable and flexible. For example, the material of the first teeth 350 and the second teeth 360 can be changed to suit the type of material, including but not limited to stainless steel, high-carbon steel, cemented tungsten carbide steel, high-speed steel, etc.

[0083] like Figure 2 As shown, in one embodiment, a material channel 340 is provided on the mounting shell 110, and the material channel 340 connects the working chamber 130 with the outside world. The fixed plate 320 is detachably mounted on the material channel 340 to block the material channel 340. For example, one side of the fixed plate 320 is hingedly mounted on the mounting shell 110, and the other end of the fixed plate 320 is pinned to the mounting shell 110. For example, as Figure 1 As described above, the fixed disk 320 blocks the material channel 340; Figure 2 As shown, the fixing disk 320 is released from the pin connection with the mounting shell 110 , and the fixing disk 320 opens the material passage 340 .

[0084] By designing the fixing plate 320 to be detachably mounted on the material passage 340 and allowing it to be opened or closed by means of hinges and pins, this design allows for easy maintenance and cleaning of the mechanical structure when necessary. For example, when cleaning the working chamber 130 or inspecting internal components, the fixing plate 320 can be simply opened without disassembling the entire mounting housing 110 or other complex components.

[0085] like Figure 1 and Figure 2 As shown, the fixed plate 320 is provided with a feed port, through which the working chamber 130 communicates with the outside world. A feed hopper 330 is provided at the feed port. The feed hopper 330 at the feed port guides material smoothly into the working chamber 130, reducing accumulation and blockage of material in the channel. This helps improve material conveying efficiency and reduces production delays caused by poor material flow.

[0086] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
