[0002] High-pressure dry grinding equipment is a device that uses high-pressure airflow to drive abrasive particles to perform dry grinding on the surface of an object. High-speed airflow is generated by a high-pressure air source, which accelerates the abrasive particles and sprays them onto the surface of the object being processed. The impact and friction of the abrasive particles are used to grind, polish, and remove rust from the surface of the object, so as to improve surface quality, increase smoothness, remove impurities, and change the surface shape.

[0003] A bidirectional sealing device for high-pressure dry grinding equipment is installed on such equipment to prevent bidirectional leakage of gas, dust, and abrasive media, ensuring stable operation of the equipment under high pressure and dry grinding conditions. This device typically consists of multiple sealing elements.

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.

[0031] Reference Figure 1 , Figure 3 and Figure 4 This utility model provides an embodiment of a bidirectional sealing device suitable for high-pressure dry grinding equipment, comprising a fixed frame 1, a grinding shell 3 fixedly connected to an adjacent side of the inner wall of the fixed frame 1, a fixed shell 4 fixedly connected to the right side of the outer wall of the right fixed frame 1, a motor 5 fixedly connected to the front side of the outer wall of the fixed shell 4, a connecting rod 6 fixedly connected to the output end of the motor 5, a rotating rod 7 rotatably connected to the front side of the outer wall of the connecting rod 6, bevel gears 8 fixedly connected to the front and rear ends of the outer wall of the rotating rod 7, rolling rollers 10 rotatably connected to an adjacent side of the inner wall of the fixed frame 1, and bevel gears 9 fixedly connected to the right side of the outer walls of both rolling rollers 10. 8 meshes with bevel gear 9. A sealing cylinder 11 passes through the right side of the outer wall of the rolling roller 10. A sealing ring 13 is fixedly connected to the middle of the inner wall of the sealing cylinder 11. A sealing ring 15 is fixedly connected to the right side of the outer wall of the sealing ring 13. A spring 12 is fixedly connected around the outer wall of the sealing ring 15. A sealing gasket 14 is fixedly connected to the left side of the outer wall of the sealing ring 13. A rotating shaft 16 is rotatably connected to the front and rear sides of the inner wall of the fixing frame 1. A grinding mechanism 2 is fixedly connected to the top of the outer wall of the fixing frame 1. The grinding mechanism 2 is used for preliminary grinding. A protective shell 22 is fixedly connected to the top of the outer wall of the grinding shell 3. A funnel 21 is fixedly connected to the top of the outer wall of the protective shell 22.

[0032] Specifically, the bidirectional sealing device is based on the fixed frame 1, powered by the motor 5. The connecting rod 6 and the rotating rod 7 drive the bevel gear 8 to rotate, which in turn drives the rolling roller 10 to rotate on the inner wall of the fixed frame 1. The rolling roller 10 is used for material conveying and extrusion. The sealing ring 13, sealing ring 15 and spring 12 in the sealing cylinder 11 form a sealing structure to prevent dust and gas leakage. The rotating shaft 16 assists in the stable operation of the device, ensuring the reliability of sealing and power transmission. The fixed frame 1 serves as the basic support structure, on which the grinding mechanism 2 is fixedly connected to undertake the preliminary grinding task and pre-processes the material. The grinding shell 3 receives the material after the preliminary processing by the grinding mechanism 2. The protective shell 22 on the top protects the internal structure from external debris and provides a mounting base for the funnel 21. The funnel 21 is open, which facilitates the smooth flow of material into the grinding shell 3. The entire process is from the material entering through the funnel 21, being pre-ground by the grinding mechanism 2, and then being further processed in the grinding shell 3, to the orderly progress of material grinding and processing.

[0033] Reference Figure 1 , Figure 2 and Figure 5 The grinding mechanism 2 includes a support plate 201, which is fixedly connected to the top of the outer wall of the fixed frame 1. A motor 202 is fixedly connected to the right side of the outer wall of the support plate 201. A metal gear 1 203 is fixedly connected to the output end of the motor 202. A metal gear 204 is rotatably connected to the right side of the outer wall of the support plate 201. The rear metal gear 204 meshes with the metal gear 1 203. A push rod 206 is slidably connected to the top right side of the support plate 201. A metal gear 3 205 is rotatably connected to the right side of the outer wall of the push rod 206. The front metal gear 204 meshes with the metal gear 3 205. Grinding shafts 207 are fixedly connected to the left ends of the outer walls of both the metal gear 3 205 and the metal gear 1 203. An auxiliary shaft 18 is slidably connected to the top right side of the support plate 201. A rotating rod 17 is fixedly connected to the right side of the outer wall of the auxiliary shaft 18. An inclined plate 19 is fixedly connected to the bottom right side of the support plate 201. Connection holes 20 are opened on the left and right sides of the outer wall of the inclined plate 19.

[0034] Specifically, the grinding mechanism 2 uses the support plate 201 as a base and is fixed to the top of the fixed frame 1. The power source is a motor 202, which drives the metal gear 1 203 to rotate after being powered on. Then, through the meshing transmission of the metal gear 2 204 and the metal gear 3 205, the push rod 206 is pushed to slide. The metal gear 1 203 and the metal gear 3 205 are connected to the grinding shaft 207. When rotating, the material is ground. The mechanism completes the grinding through the power of the motor 202 and the multi-stage gear transmission. The support plate 201 serves as a basic support and positioning element. The auxiliary shaft 18 is slidably connected to the support plate 201, allowing it to slide on the plate to adjust the position of the component or achieve displacement. The rotating rod 17 is fixed to the outer wall of the auxiliary shaft 18 and slides and rotates with it to transmit power or change the direction of movement. The inclined plate 19 is fixed to the bottom of the support plate 201 to provide guidance or assist the flow of material. Its connection hole 20 can be used to connect with the support plate 201 to ensure that the device works together to achieve specific functions.

[0035] Reference Figure 1 , Figure 2 and Figure 3 The bottom front of the grinding shell 3 is rotatably connected to a guide tube 23, the top right side of the fixing frame 1 is fixedly connected to a support frame 24, the bottom front of the fixing frame 1 is provided with multiple fixing holes 25, the inner wall of the fixing hole 25 is slidably connected to a pin 26, the bottom four corners of the fixing frame 1 are fixedly connected to foot pads 27, and the top four corners of the fixing frame 1 are fixedly connected to protective pads 28.

[0036] Specifically, the guide tube 23 rotatably connected to the bottom front of the grinding shell 3 can guide the material direction, and the fixing frame 1 is supported by the support frame 24 on the top right side; the fixing hole 25 on the bottom front of the fixing frame 1 cooperates with the pin 26 to fix and support the guide tube 23; the foot pads 27 at the four corners of the bottom play a role in stabilizing support and anti-slip and shock absorption, while the protective pads 28 at the four corners of the top can protect the equipment above, reduce the risk of collision damage, and jointly ensure the stable operation of the equipment.

[0037] Working principle: This bidirectional sealing device is based on the fixed frame 1. The components cooperate to achieve sealing and power transmission functions. The motor 5 serves as the power source. After being powered on, it outputs power to drive the connecting rod 6 to rotate. The rotating rod 7 rotates with the connecting rod 6, and the bevel gear 8 at the front and rear ends of its outer wall also rotates. The bevel gear 8 meshes with the bevel gear 9 on the right side of the outer wall of the rolling roller 10, thereby transmitting power to the rolling roller 10. This causes the rolling roller 10 to rotate on the inner wall of the fixed frame 1, which can be used for material conveying and extrusion. The right side of the outer wall of the rolling roller 10 passes through the sealing cylinder 11. The sealing ring 13, sealing ring 15, and sealing gasket 14 inside the sealing cylinder 11 together form a sealing structure. The spring 12 causes the sealing ring 15 to exert pressure on the sealing ring 13. The sealing ring 13 and sealing gasket 14 are tightly attached to the rolling roller 10 to form a bidirectional seal, preventing the leakage of dust and gas when the high-pressure dry grinding equipment is working. At the same time, the rotating shaft 16 rotates on the inner wall of the fixed frame 1, which assists in the stable operation of the entire device and ensures the stability and reliability of sealing and power transmission.

[0038] The grinding mechanism 2 is supported by a support plate 201 and fixed to the top of the mounting frame 1. The power input motor 202 serves as the power source. When it is powered on, its output end begins to rotate, driving the metal gear 203 fixedly connected to it to rotate. Since the rear metal gear 204 meshes with the metal gear 203, the rotation of the metal gear 203 will drive the rear metal gear 204 to rotate through the interaction force between its teeth. The front metal gear 204 meshes with the metal gear 205. When the rear metal gear 204 rotates, it will drive the coaxial front metal gear 204 to rotate together, thus causing the front metal gear 205 to rotate as well. The metal gear 205 meshing with the second gear 204 also begins to rotate. At the same time, the rotation of the metal gear 205 pushes the push rod 206 connected to it to slide on the top right side of the support plate 201. The grinding shaft 207 is fixedly connected to the left end of the outer wall of both the metal gear 205 and the first gear 203. During the rotation of the first gear 203 and the third gear 205, they will drive the grinding shaft 207 connected to them to rotate. The rotating grinding shaft 207 can grind the material. The grinding mechanism 2 is powered by the motor 202. After multi-stage gear transmission, it finally drives the grinding shaft 207 to rotate to complete the grinding work of the material.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
