[0002] Grinding equipment is a mechanical device used to grind various materials into fine or ultrafine powders. It is widely used in food, medicine, chemical, building materials, mining, agriculture and many other fields. Grinding equipment typically consists of a drive unit (motor, reducer), a grinding chamber, grinding media (such as grinding rollers, grinding discs, hammers, steel balls, etc.), a classification system (such as cyclone separators, screens, air classifiers), and a dust collection device. After the material enters the grinding chamber, it is repeatedly impacted, rubbed and sheared under the action of high-speed rotating grinding media or airflow, gradually refined to the target particle size. Then, qualified fine powder is separated by the classification system, while coarse particles are returned for further grinding. According to the differences in grinding principle and structure, grinding equipment can be divided into mechanical type (such as Raymond mill, ball mill, air jet mill, ultrafine pulverizer), air jet type (such as fluidized bed air jet mill), impact type (such as impact pulverizer), and shear type (such as colloid mill).

[0042] Example

[0043] Please refer to Figure 1-6 As shown, this embodiment provides a food grinding device to prevent nutrient loss, including a drive unit 1, a grinding unit 2, and a cooling unit 3. The grinding unit 2 includes a housing 21, a gear ring assembly, and a hammer assembly 23. The gear ring assembly is fixed inside the housing 21, and its bottom surface is spaced apart from the housing 21 to form a cooling chamber 24. A drive rod assembly 11 is connected to the drive end of the drive unit 1, and the drive rod assembly 11 passes through the housing 21. The hammer assembly 23 is disposed inside the gear ring assembly and rotatably connected to the drive rod assembly 11; a first cooling pipe 111 is formed inside the drive rod assembly 11. The cooling unit 3 includes a drive assembly and a cooling pipe 32 connected to each other. The cooling pipe 32 communicates with the cooling chamber 24 and the first cooling pipe 111. The drive assembly drives coolant to the cooling chamber 24 and the first cooling pipe 111 through the cooling pipe 32.

[0044] The drive unit 1 drives the hammer assembly 23 to rotate via the drive rod assembly 11, which works in conjunction with the gear ring assembly to crush and grind the material. The drive assembly transmits coolant to the cooling chamber 24 and the first cooling pipe 111 via the cooling pipe 32. The coolant in the cooling chamber 24 cools the gear ring assembly, preventing the gear ring assembly from overheating due to friction and heating the material. The first cooling pipe 111 and the coolant also cool the drive rod assembly 11, thereby cooling the connection between the drive rod assembly 11 and the hammer assembly 23. This prevents the accumulated powder at the connection between the hammer assembly 23 and the drive rod assembly 11 from heating up, achieving comprehensive cooling of the inside of the grinding device and minimizing the overheating of the material powder and loss of nutrients.

[0045] Please refer to Figure 2 and Figure 3As shown, specifically, the cooling unit 3 also includes a water tank 33, and the drive assembly is connected to the water tank 33. The cooling pipe 32 includes an inlet pipe 321 and an outlet pipe 322. One end of the inlet pipe 321 is connected to the drive assembly, and the other end of the inlet pipe 321 is connected to the inlet end of the first cooling pipe 111 and the cooling chamber 24. One end of the outlet pipe 322 is connected to the outlet end of the first cooling pipe 111 and the cooling chamber 24, and the other end of the outlet pipe 322 is connected to the water tank 33. The water tank 33, the inlet pipe 321, the cooling chamber 24, the first cooling pipe 111, and the outlet pipe 322 form a water circulation system, realizing the recycling and reuse of the coolant, making full use of cooling resources, and reducing cooling costs.

[0046] Specifically, the inlet pipe 321 includes a main pipe 3211, a first branch pipe 3212, and a second branch pipe 3213. One end of the main pipe 3211 is connected to the drive assembly, and the other end of the main pipe 3211 is connected to the first branch pipe 3212 and the second branch pipe 3213 via a three-way valve 3214. The first branch pipe 3212 is connected to the inlet end of the first cooling pipe 111 via a rotary joint 34, and the second branch pipe 3213 is connected to the inlet end of the cooling chamber 24. Similarly, the outlet pipe 322 is connected to the outlet end of the first cooling pipe 111 via a rotary structure. Water is supplied to the first cooling pipe 111 and the cooling chamber 24 via the first branch pipe 3212 and the second branch pipe 3213 respectively, improving the smooth flow of coolant in the cooling loop. Furthermore, an overflow valve 323 is installed on the main pipe 3211. The overflow valve 323 is connected to the water tank 33. The overflow valve 323 releases the water pressure in the cooling pipe 32 to prevent the water from flowing too fast in some pipes due to the difference in path length between the cooling chamber 24 loop and the first cooling pipe 111 loop, which would cause liquid leakage and affect the material powdering effect.

[0047] Please refer to Figure 5 As shown, a second cooling pipe 241 is further provided within the cooling chamber 24, and a second branch pipe 3213 is connected to the second cooling pipe 241. In this embodiment, the second cooling pipe 241 is distributed in an S-shape within the cooling chamber 24, making full use of the space within the cooling chamber 24 and providing a better cooling effect for the gear ring assembly. A flow control valve 324 is provided on the second branch pipe 3213 to control the flow rate of the second branch pipe 3213, so that the flow rates of the first branch pipe 3212 and the second branch pipe 3213 are balanced, avoiding excessively fast coolant flow and improving the cooling effect.

[0048] Please refer to Figure 2 , Figure 3 and Figure 6As shown, specifically, the drive rod assembly 11 includes a main rod 112 and a mounting rod 113. The end of the main rod 112 is rotatably connected to the drive unit 1. The main rod 112 has outwardly protruding mounting portions 1121 on its two circumferential sides. The mounting rod 113 passes between the mounting portions 1121, and the hammer assembly 23 is rotatably connected to the mounting rod 113. The main rod 112 drives the mounting rod 113 to rotate, thereby causing the hammer assembly 23 to rotate along the mounting rod 113. Simultaneously, the mounting rod 113 and the main rod 112 are separated, allowing for the installation of more sets of hammer assemblies 23. This fully utilizes the internal space of the gear ring assembly, enabling different hammer assemblies 23 to hammer the material at different positions, improving hammering efficiency and enhancing the crushing effect.

[0049] Furthermore, a first pipe 1111 is formed inside the main rod 112, extending inward from both ends of the main rod 112 and passing through the mounting part 1121. A second pipe 1112 is formed inside the mounting rod 113. The first pipe 1111 and the second pipe 1112 are interconnected, forming a first cooling pipe 111. Plugs 114 are provided at the ends of the first pipe 1111 and both ends of the second pipe 1112. Coolant enters through the first pipe 1111 at one end of the main rod 112, flows through the second pipe 1112, and finally flows out through the first pipe 1111 at the other end of the main rod 112, cooling the mounting rod 113 and thus achieving cooling at the connection point between the mounting rod 113 and the hammer assembly 23.

[0050] The mounting part 1121 has a mounting hole 1122. The end of the mounting rod 113 passes through the mounting hole 1122. A sealing element 115 is fixed on the inner wall of the mounting hole 1122. The sealing element 115 surrounds the connection position of the first pipe 1111 and the second pipe 1112. In this embodiment, the sealing element 115 is a sealing ring. The sealing ring and the plug 114 achieve a seal on the first cooling pipe 111, preventing coolant from overflowing from the first cooling pipe 111 and falling into the toothed ring, which would affect the crushing effect.

[0051] Specifically, the drive unit 1 includes a drive motor 12 and a bearing housing 13. Both ends of the drive rod assembly 11 are rotatably mounted on the bearing housing 13. In this embodiment, the drive motor 12 and the bearing housing 13 are fixed to the water tank 33. The drive end of the drive motor 12 is connected to a first driving wheel 121, and one end of the drive rod assembly 11 is provided with a first driven wheel 122. A first transmission belt 123 is wound between the first driving wheel 121 and the first driven wheel 122. In this embodiment, the rotating rods at both ends of the main rod 112 are mounted on the bearing housing 13, and the drive motor 12 drives the main rod 112 to rotate via the first driving wheel 121 and the first driven wheel 122.

[0052] Furthermore, the drive assembly includes a gear pump 31, with a second driven wheel 125 at its drive end and a second driving wheel 124 connected to the drive end of the drive motor 12. A second transmission belt 126 is wound between the second driving wheel 124 and the second driven wheel 125. The inlet end of the gear pump 31 is connected to the water tank 33, and the other end of the gear pump 31 is connected to the inlet pipe 321. The drive motor 12 drives the gear pump 31 through the second driving wheel 124 and the second driven wheel 125 to extract coolant from the water tank 33. The pulverizing and cooling operations are performed simultaneously. When pulverizing is not in progress, the cooling operation is stopped simultaneously to avoid energy waste and reduce the number of drive devices, thus lowering costs.

[0053] Please refer to Figure 4 As shown, specifically, the housing 21 includes an upper housing 211 and a lower housing 212, with a connector 213 between them. In this embodiment, the connector 213 is a bolt. The gear ring assembly includes an upper gear ring (not shown in the figures) and a lower gear ring 22. The upper gear ring is fixed inside the upper housing 211, and the lower gear ring 22 is fixed inside the lower housing 212. The bottom surface of the lower gear ring 22 is spaced apart from the lower housing 212. The upper housing 211 and the lower housing 212 are detachably connected by bolts, facilitating the opening of the housing 21 for inspection of the internal space of the gear ring assembly and preventing material powder accumulation or blockage inside the housing 21, which could affect the stability of the grinding operation.

[0054] In this embodiment, a feeding assembly 4 is fixed on the housing 21, and the feeding assembly 4 is connected to the inside of the housing 21. A discharge drive assembly is fixed inside the housing 21, and a discharge port 214 is provided. The material enters the toothed ring assembly through the feeding assembly 4, and after being crushed and powdered by the toothed ring assembly and the locking head assembly, the discharge drive assembly drives the powder to be discharged from the discharge port 214.

[0055] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
