Description

Technical Field

[0001] This utility model belongs to the field of roller mill technology, specifically relating to a device for grinding ceramic raw materials using a high-pressure roller mill. Background Technology

[0002] The working principle of a high-pressure roller mill is mainly to crush materials through the high pressure between two counter-rotating rollers. After the material enters the high-pressure roller mill, it is compressed between the two high-pressure rollers to form a material layer, and then crushed into smaller particles under high pressure. In the recycling of waste ceramics, high-pressure roller mills are often needed to grind the recycled waste ceramic raw materials. However, during the grinding process, some particles often do not meet the particle size requirements and need to be screened separately after output. The oversized particles are then put back into the roller mill for grinding, requiring multiple transfers, which is time-consuming, requires a lot of manpower, and significantly affects the crushing efficiency and effect of the material. Utility Model Content

[0003] To address the above problems, the purpose of this utility model is to provide a device for grinding ceramic raw materials using a high-pressure roller mill. This device automatically screens the ground material and automatically recovers materials that do not meet the particle size requirements. It also automatically feeds these materials back into the roller mill for secondary grinding, which greatly improves the grinding efficiency and effect.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a device for grinding ceramic raw materials using a high-pressure roller mill, comprising a base, a support mounted on the top of the base, a first housing fixedly mounted on the top of the support and a second housing pin-connected thereto, a fixed roller rotatably mounted on the inner side of the first housing, a moving roller rotatably mounted on the inner side of the second housing, a screening device bracket mounted on the top of the base, a screening box mounted on the top of the screening device bracket, a spring telescopic rod mounted on the inner side of the screening box, the bottom end of the spring telescopic rod connected to a screen, a second motor mounted on the side of the screening box, the output end of the second motor connected to an eccentric wheel, a discharge pipe mounted on the side of the screening box, a receiving and lifting device connected to the side of the screening box, the receiving and lifting device comprising a receiving box, a feed inlet connected to one side of the receiving box, the feed inlet communicating with the screening box, a lifting cylinder inserted into the top of the receiving box, a recovery pipe connected to the top side of the lifting cylinder, a third motor mounted on the top of the lifting cylinder, the output end of the third motor connected to a screw conveyor shaft.

[0005] The beneficial effects of this invention are as follows: After the ceramic material is ground by a fixed roller and a moving roller, the pulverized material particles are discharged into a screening box through the discharge port. A second motor drives an eccentric wheel to rotate, which in turn moves the screen downwards, compressing the spring telescopic rod. When the protruding end of the eccentric wheel disengages from the screen, the screen springs back up under the restoring force of the spring telescopic rod, throwing the material that fell onto the screen. Through the reciprocating motion of the screen, the ground material is screened, and particles that meet the required size pass through the screen and fall to the bottom of the screening box. The material is discharged through the discharge pipe, while larger particles slide diagonally downwards along the screen and flow into the receiving box through the feed inlet. The third motor drives the screw conveyor shaft to rotate, and the screw conveyor shaft and the lifting cylinder work together to lift the material in the receiving box upwards. The material is then fed back into the feed channel through the recovery pipe for secondary crushing. The automatic screening of the ground material and the automatic recovery of material that does not meet the particle size standard, combined with the function of automatically feeding this part of the material back into the roller mill for secondary crushing, greatly improves the crushing efficiency and effect.

[0006] In order to grind ceramic raw materials:

[0007] As a further improvement to the above technical solution: a first motor is provided on the side of both the first and second housings, and one end of the fixed roller and the moving roller are connected to the first motor.

[0008] The beneficial effects of this improvement are: the operation of the first motor drives the fixed roller and the moving roller to rotate respectively, thereby grinding the ceramic raw materials.

[0009] As a further improvement to the above technical solution: hydraulic cylinder mounting seats are installed on the top of the first housing and the second housing, and the hydraulic cylinder mounting seats on the top of the first housing and the second housing are respectively pin-connected to the two ends of the hydraulic cylinder.

[0010] The beneficial effects of this improvement are as follows: Firstly, the hydraulic cylinder serves to traction and limit the second casing, creating a relatively stable positional relationship between it and the first casing. Secondly, due to the hydraulic cylinder and the rotatable pin connection between the second casing and the support, the second casing can adaptively rotate according to the particle size of the raw material. At the same time, the hydraulic cylinder maintains the pressure intensity between the fixed roller and the moving roller, achieving dynamic adjustment and pressure control, improving crushing efficiency and energy efficiency ratio, and adapting to the crushing requirements of different materials.

[0011] For material to be fed into the first and second casings:

[0012] As a further improvement to the above technical solution: the inner sides of the first housing and the second housing are provided with feeding channel brackets, and the sides of the feeding channel brackets are provided with feeding channels.

[0013] The beneficial effects of this improvement are: the feed channel is used to feed materials into the interior of the first and second casings for grinding.

[0014] In order to discharge the ground material into the screening box:

[0015] As a further improvement to the above technical solution: the bottom of the first housing and the second housing are provided with discharge ports.

[0016] The beneficial effect of this improvement is that the discharge port is used to discharge the ground material into the screening box.

[0017] To allow recycled materials to be directly fed into the feed channel:

[0018] As a further improvement to the above technical solution: one end of the recovery tube is aligned with the feed channel.

[0019] The beneficial effects of this improvement are: one end of the recovery pipe is aligned with the feed channel, and the collected material that has been ground to the required standard can be directly fed into the feed channel.

[0020] The parts of the device not covered herein are the same as or can be implemented using existing technologies. Attached Figure Description

[0028] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of the present invention in any way.

[0029] like Figure 1-6 As shown, a device for grinding ceramic raw materials using a high-pressure roller mill includes a base 1, a support 2 mounted on the top of the base 1, a first housing 3 fixedly mounted on the top of the support 2 and a second housing 4 pinned to it, a fixed roller 5 rotatably mounted on the inner side of the first housing 3, a moving roller 6 rotatably mounted on the inner side of the second housing 4, a screening device bracket 13 mounted on the top of the base 1, a screening box 26 mounted on the top of the screening device bracket 13, a spring telescopic rod 14 mounted on the inner side of the screening box 26, the bottom end of the spring telescopic rod 14 connected to a screen 15, and a second roller 6 mounted on the side of the screening box 26. Two motors 16 are connected to each other. The output end of the second motor 16 is connected to the eccentric wheel 17. A discharge pipe 18 is installed on the side of the screening box 26. A receiving and lifting device 19 is connected to the side of the screening box 26. The receiving and lifting device 19 includes a receiving box 20. A feed inlet 21 is connected to one side of the receiving box 20. The feed inlet 21 communicates with the screening box 26. A lifting cylinder 22 is inserted and installed at the top of the receiving box 20. A recovery pipe 24 is connected to the top side of the lifting cylinder 22. A third motor 25 is installed at the top of the lifting cylinder 22. The output end of the third motor 25 is connected to the screw conveyor shaft 23.

[0030] After the ceramic material is ground by the fixed roller 5 and the moving roller 6, the pulverized material particles are discharged into the screening box 26 through the discharge port 12. The second motor 16 drives the eccentric wheel 17 to rotate, which in turn moves the screen 15 downwards, compressing the spring telescopic rod 14. When the protruding end of the eccentric wheel 17 disengages from the screen 15, the screen 15 springs back up under the restoring force of the spring telescopic rod 14, throwing the material that fell on it up. Through the reciprocating motion of the screen 15, the ground material is screened. Particles that meet the required size pass through the screen 15 and fall to the bottom of the screening box 26. Material that is discharged through the discharge pipe 18, while material with a larger particle size slides obliquely downward along the screen 15 and flows into the receiving box 20 through the feed inlet 21. The screw conveyor shaft 23 is driven to rotate by the third motor 25. The screw conveyor shaft 23 and the lifting cylinder 22 work together to lift the material in the receiving box 20 upward and put it back into the feed channel 11 through the recovery pipe 24 for secondary crushing. The automatic screening of the ground material and the automatic recovery of material with a particle size that does not meet the standard, combined with the function of automatically feeding this part of the material back into the roller mill for secondary crushing, greatly improves the crushing efficiency and effect.

[0031] The first housing 3 and the second housing 4 are each provided with a first motor 7 on their sides, and one end of the fixed roller 5 and the moving roller 6 are both connected to the first motor 7.

[0032] The operation of the first motor 7 drives the fixed roller 5 and the moving roller 6 to rotate respectively, and grinds the ceramic raw materials.

[0033] Hydraulic cylinder mounting seats 8 are installed on the top of the first housing 3 and the second housing 4. The hydraulic cylinder mounting seats 8 on the top of the first housing 3 and the second housing 4 are respectively pin-connected to the two ends of the hydraulic cylinder 9.

[0034] The hydraulic cylinder 9 serves two purposes: firstly, it provides traction and limit to the second housing 4, ensuring a relatively stable positional relationship between it and the first housing 3; secondly, due to the hydraulic cylinder 9 and the rotatable pin connection between the second housing 4 and the support 2, the second housing 4 can adaptively rotate according to the particle size of the raw material. Simultaneously, the hydraulic cylinder 9 maintains the pressure intensity between the fixed roller 5 and the moving roller 6, enabling dynamic adjustment and pressure control, improving crushing efficiency and energy efficiency ratio, and adapting to the crushing requirements of different materials.

[0035] The inner sides of the first housing 3 and the second housing 4 are provided with feeding channel brackets 10, and the side of the feeding channel brackets 10 is provided with feeding channels 11.

[0036] The feeding channel 11 is used to feed materials into the interior of the first casing 3 and the second casing 4 for grinding.

[0037] The bottom of the first housing 3 and the second housing 4 are provided with discharge ports 12.

[0038] The discharge port 12 is used to discharge the ground material into the screening box 26.

[0039] One end of the recovery pipe 24 is aligned with the feed channel 11.

[0040] One end of the recovery pipe 24 is aligned with the feed channel 11. The collected material that has been ground to the required standard can be directly fed into the feed channel 11.

[0041] The working principle and usage process of this utility model are as follows: When using this device, the ceramic raw material to be ground is poured into the inner side of the first housing 3 and the second housing 4 through the feeding channel 11. The first motor 7 drives the fixed roller 5 and the moving roller 6 to rotate, grinding the raw material. Because a hydraulic cylinder 9 is installed, and the second housing 4 is rotatably connected to the support 2, the second housing 4 can adaptively rotate according to the particle size of the raw material. Simultaneously, the hydraulic cylinder 9 maintains the pressure intensity between the fixed roller 5 and the moving roller 6, achieving dynamic adjustment and pressure control, improving grinding efficiency and energy efficiency ratio, and adapting to the grinding requirements of different materials. The ground material particles are discharged into the screening box 26 through the discharge port 12. The second motor 16 drives the eccentric wheel 17 to rotate, causing the eccentric wheel 17 to move the screen 15 downwards, compressing the spring telescopic rod 14. When the protruding end of the eccentric wheel 17 disengages from the screen 15... Under the rebound force of the spring telescopic rod 14, the screen 15 springs up and resets, throwing the material falling on the screen 15 up. Through the up-and-down reciprocating motion of the screen 15, the ground material is screened. The particles that meet the requirements pass through the screen 15 and fall to the bottom of the screening box 26 and are discharged through the discharge pipe 18. The materials with larger particle sizes slide obliquely downward along the screen 15 and flow into the receiving box 20 through the feed inlet 21. The screw conveyor shaft 23 is driven to rotate by the third motor 25. The screw conveyor shaft 23 and the lifting cylinder 22 work together to lift the material in the receiving box 20 upward and put it back into the feed channel 11 through the recovery pipe 24 for secondary crushing. By automatically screening the ground material and automatically recovering the material that does not meet the particle size requirements, and by automatically feeding this part of the material back into the roller mill for secondary crushing, the crushing efficiency and effect are greatly improved.
