Abstract
Description
Technical Field
[0001] This utility model relates to the field of grinding machine technology, specifically to a heat insulation device for preventing high-temperature conduction in an ultrafine grinding mixer. Background Technology
[0002] Household grinders can grind grains, coffee, spices, and other ingredients. They can also be used to crush nuts and grind herbs, making ingredients fresher and more nutritious, thus making life more delicious and healthy. In food nutrient extraction, grinding is a simple, efficient, and widely used method. Grinding can turn food into fine powder, making it easier to extract nutrients and allowing consumers to better absorb them.
[0003] However, existing grinding equipment usually lacks effective heat insulation measures to reduce the heat conduction of materials during the grinding process, so as to reduce the temperature loss of materials and avoid the risk of users being burned.
[0004] As disclosed in CN218554212U, a graphite pulverizing, grinding, and mixing machine includes: a casing with a feed hopper on its top; a pulverizing mechanism for graphite pulverizing on the top of the casing; a support plate on the bottom of the inner wall of the casing; an inclined surface on the upper surface of the support plate; and a grinding mechanism on the support plate. The grinding mechanism includes a second motor, a rotating column, a protective cover, and multiple grinding roller assemblies. The second motor and the protective cover are respectively located at both ends of the rotating column. The grinding roller assembly includes a rotating rod and a grinding roller body, and the multiple grinding roller bodies are rolledly connected to the upper surface of the inclined surface. This utility model utilizes the coordinated arrangement of the pulverizing mechanism, the support plate, the inclined surface, and the grinding mechanism. The starting of the second motor facilitates the grinding of graphite by the grinding roller bodies on the support plate. The inclined surface ensures that the graphite powder is stably set around the periphery of the support plate and squeezed and ground by the grinding rollers, thereby improving grinding efficiency. However, this utility model lacks effective heat insulation measures, which can easily lead to the heat inside the machine being conducted to the outside of the machine, affecting the quality of the working environment. At the same time, it is also not easy to ensure the safety of operators. Therefore, we propose a heat insulation device to prevent high temperature conduction in an ultrafine grinding mixer. Utility Model Content
[0005] The purpose of this invention is to provide a heat insulation device for preventing high-temperature conduction in an ultrafine grinding mixer, so as to solve the heat insulation problem of the grinding machine during operation mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution:
[0007] A heat insulation device for preventing high-temperature conduction in an ultrafine grinding mixer includes a grinding cylinder body. The grinding cylinder body includes a grinding cylinder outer shell, and a grinding inner cylinder is fixedly installed inside the grinding cylinder outer shell. A heat insulation and noise reduction mechanism is provided between the grinding cylinder outer shell and the grinding inner cylinder. A driving mechanism is provided at the bottom end of the grinding cylinder outer shell. The heat insulation and noise reduction mechanism includes a vacuum chamber. The cavity between the grinding cylinder outer shell and the grinding inner cylinder is a vacuum chamber. An air extraction hole is provided on one side of the vacuum chamber. An air pipe connector is fixedly installed in the air extraction hole. An external thread is provided on the outside of the air pipe connector. A sealing cap is threaded onto the external thread. A mineral wool layer is fixedly pasted on the inner wall of the grinding cylinder outer shell. The end of the air pipe connector away from the sealing cap penetrates the mineral wool layer and extends into the vacuum chamber.
[0008] Preferably, the grinding cylinder has an annular groove at its top end, and the grinding cylinder is fitted with a cover. A sealing ring is pasted inside the cover, and the sealing ring fits into the annular groove.
[0009] Preferably, a discharge port is fixedly provided on the bottom side of the grinding cylinder, a valve is installed on the outside of the discharge port, and a convenient handle is fixedly provided on the top of the cover.
[0010] Preferably, the driving mechanism includes a servo motor, the output end of which is fixedly connected to a drive shaft, the top end of which passes through the bottom end of the grinding cylinder and extends into the interior of the grinding cylinder.
[0011] Preferably, a grinding blade is fixedly installed on the outside of the drive shaft, a motor protective box is fixedly installed on the outside of the servo motor, a heat dissipation mesh plate is installed on one side of the motor protective box, a bottom pad is fixedly connected to the bottom of the motor protective box, and the bottom pad has auxiliary fixing holes.
[0012] Preferably, the sealing ring is made of butyl rubber, fluorosilicone rubber, or silicone rubber with good heat resistance, and the mineral wool layer has a thickness of 8-12 mm.
[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] This heat insulation device for preventing high-temperature conduction in an ultrafine grinding mixer achieves heat insulation for the grinding inner cylinder by setting a vacuum cavity between the outer shell and the inner cylinder. Since there is no heat conduction medium in the vacuum state, heat cannot be transferred by conduction and convection, thus achieving the heat insulation effect of the inner cylinder.
[0015] This heat insulation device for preventing high-temperature conduction in an ultrafine grinding mixer uses an 8-12mm thick mineral wool layer pasted on the inner wall of the grinding cylinder shell. Due to the excellent heat insulation and sound absorption properties of the mineral wool layer, the heat insulation effect of the grinding cylinder is further improved. At the same time, it also reduces the noise generated by the device during grinding operations, thus improving the user experience. Attached Figure Description

[0022] Please see Figures 1-4 As shown, this utility model provides a technical solution:
[0023] A heat insulation device for preventing high-temperature conduction in an ultrafine grinding mixer includes a grinding cylinder 100, which includes a grinding cylinder outer shell 101. A grinding inner cylinder 102 is fixedly installed inside the grinding cylinder outer shell 101. A heat insulation and noise reduction mechanism is provided between the grinding cylinder outer shell 101 and the grinding inner cylinder 102. A driving mechanism is provided at the bottom of the grinding cylinder outer shell 101. The heat insulation and noise reduction mechanism includes a vacuum chamber 200. The cavity between the grinding cylinder outer shell 101 and the grinding inner cylinder 102 is the vacuum chamber 200. An air extraction hole 201 is provided on one side of the vacuum chamber 200. An air pipe connector 202 is fixedly installed on the air extraction hole 201. An external thread 203 is provided on the outside of the air pipe connector 202. A sealing cap 204 is threadedly connected to the external thread 203. A mineral wool layer 205 is fixedly pasted on the inner wall of the grinding cylinder outer shell 101. The end of the air pipe connector 202 away from the sealing cap 204 passes through the mineral wool layer 205 and extends into the vacuum chamber 200.
[0024] In this embodiment, preferably, the grinding cylinder 100 has an annular groove 103 at its top end, and the grinding cylinder 100 is equipped with a cover 104. A sealing ring 105 is pasted inside the cover 104, and the sealing ring 105 and the annular groove 103 are fitted together.
[0025] In this embodiment, preferably, a discharge port 106 is fixedly provided on the bottom side of the grinding cylinder 100, a valve 107 is installed on the outside of the discharge port 106, and a convenient handle 108 is fixedly provided on the top of the cover 104.
[0026] In this embodiment, preferably, the driving mechanism includes a servo motor 300, the output end of which is fixedly connected to a drive shaft 301, the top end of which passes through the bottom end of the grinding cylinder 100 and extends into the interior of the grinding inner cylinder 102.
[0027] In this embodiment, preferably, a grinding blade 302 is fixedly installed on the outside of the drive shaft 301, a motor protective box 303 is fixedly installed on the outside of the servo motor 300, a heat dissipation mesh plate 304 is installed on one side of the motor protective box 303, a bottom pad 305 is fixedly connected to the bottom of the motor protective box 303, and the bottom pad 305 has an auxiliary fixing hole 306.
[0028] In this embodiment, preferably, the sealing ring 105 is made of butyl rubber, fluorosilicone rubber, or silicone rubber with good heat resistance, and the mineral wool layer 205 has a thickness of 8-12mm.
[0029] In this embodiment, a heat insulation device for preventing high-temperature conduction in an ultrafine grinding mixer is used.

When the vacuum environment inside the vacuum chamber 200 reaches the target value, the air pipe connector 202 is sealed with a sealing cap 204. Due to the lack of a heat conduction medium in a vacuum state, heat cannot be transferred through conduction and convection, thus achieving the heat insulation effect of the grinding inner cylinder 102. In addition, the mineral wool layer 205 pasted on the inner wall of the grinding cylinder outer shell 101 further improves the heat insulation effect of the grinding cylinder 100 due to the good heat insulation and sound absorption properties of mineral wool.

By starting the servo motor 300 to drive the drive shaft 301 to rotate, the grinding blades 302 will rotate synchronously, thus achieving the crushing and grinding effect on the material. After processing, the material can be discharged by opening the discharge port 106 valve 107.
