Description

Technical Field

[0001] This application relates to the field of refractory material production and processing technology, specifically a grinding device for the production of mullite refractory materials. Background Technology

[0002] After sintering, mullite refractory blanks require grinding to achieve precise dimensional requirements. Existing grinding devices typically suffer from the following drawbacks: First, the dust hoods are mostly fixed and cannot move closely with the grinding head, causing dust to rapidly dissipate after generation at the grinding point, resulting in low collection efficiency, severe pollution of the working environment, and equipment damage. Second, the thick dust generated during grinding instantly contaminates the observation window, requiring operators to frequently stop the machine for manual wiping, affecting production efficiency and reducing processing accuracy due to repeated start-ups and shutdowns. Third, the connection between the grinding head and the dust hood is often rigid, making them prone to collisions during loading, unloading, or adjustment, leading to deformation or damage to the dust hood. Therefore, this application proposes a grinding device for mullite refractory production to address these problems. Summary of the Invention

[0003] The technical problem to be solved by this application is to overcome the existing defects and provide a grinding device for the production of mullite refractory materials, which can effectively solve the problems in the background art.

[0004] To achieve the above objectives, this application provides the following technical solution: a grinding device for producing mullite refractory materials, comprising a worktable, a displacement structure disposed on the worktable, a grinding structure mounted on the displacement structure, and a dust removal hood covering the outside of the grinding structure, characterized in that: the dust removal hood is fixedly connected to the base of the grinding structure through a buffer structure; observation windows are provided on both side walls of the dust removal hood; and a cleaning structure for cleaning the inner surface of the observation windows is provided inside the dust removal hood;

[0005] The cleaning structure includes a nozzle and cleaning cotton facing the inner surface of the observation window, a water supply pipe connected to the nozzle, and a collection box located directly below the cleaning cotton for collecting liquid; the water supply pipe is fixed to the base of the polishing structure.

[0006] Furthermore, the buffer structure includes at least two guide rods, one end of which is fixedly connected to the dust removal hood, and the other end passes through the base of the grinding structure and slides therewith; a spring is sleeved on the guide rod, and the spring is compressed between the dust removal hood and the base of the grinding structure.

[0007] Furthermore, a limiting block is provided at the end of the guide rod.

[0008] Furthermore, the cleaning cotton is pressed onto the inner surface of the observation window by an elastic mounting bracket, the elastic mounting bracket is fixed to the water distribution plate, and the nozzle is connected to the water supply pipeline through the water distribution plate.

[0009] Furthermore, vacuum cleaners are installed on both the front and rear sides of the dust cover.

[0010] Furthermore, the dust cover has four openings, each with a groove and a soft sealing curtain on the outside.

[0011] Furthermore, the bottom of the dust removal hood is equipped with casters.

[0012] Furthermore, the displacement structure is a two-axis moving slide.

[0013] Compared with existing technologies, this application achieves synchronous movement of the dust hood and grinding head by setting up a buffer structure, which can always cover the periphery of the grinding point and efficiently capture dust from the source, greatly improving dust removal efficiency. Through the setting of the cleaning structure, dust and dirt on the observation window of the dust hood can be removed as the dust hood rises with the grinding structure, ensuring that the operator has a continuously clear observation field without interrupting production, thus improving work efficiency and safety.

[0019] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments in this application (for ease of description and understanding, hereinafter referred to as...), Figure 2(The above is described above). All other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this application.

[0020] Please see Figure 1-4 This application provides a technical solution for a grinding device for producing mullite refractory materials: a grinding device for producing mullite refractory materials includes a worktable 1, a displacement structure 2 disposed on the worktable 1, a grinding structure 3 installed on the displacement structure 2, and a dust cover 4 covering the outside of the grinding structure 3.

[0021] The worktable 1 is used to support the refractory material blank to be processed. The displacement structure 2 can drive the grinding structure 3 to move precisely in the X and Z axis directions. The grinding structure 3 includes a drive motor, a grinding wheel, and a connecting bushing, which are fixedly mounted on the moving end of the displacement structure 2 via its base 31, so that it can be driven by the displacement structure 2 to complete the grinding process on the surface of the blank.

[0022] The dust cover 4 is fixedly connected to the base 31 of the grinding structure 3 via the buffer structure 5.

[0023] Furthermore, the buffer structure 5 includes at least two guide rods 51. One end of the guide rod 51 is fixedly connected to the dust cover 4, and the other end passes through the base 31 of the grinding structure 3 and slides therewith. A spring 52 is sleeved on the guide rod 51, and the spring 52 is compressed between the dust cover 4 and the base 31 of the grinding structure 3.

[0024] Furthermore, a limiting block 53 is provided at the end of the guide rod 51 to prevent the guide rod 51 from completely dislodging from the base 31.

[0025] This design integrates the dust hood 4 and the grinding structure 3 into a single moving unit, achieving "follow-up dust removal" and capturing dust at its source. When the dust hood 4 is accidentally struck by a workpiece or fixture below, the impact force propels it upwards, compressing the spring 52. This transforms the violent rigid impact into a flexible, cushioned motion, absorbing energy and effectively protecting both the dust hood 4 and the grinding structure 3. The guide rod 51 ensures the straightness and stability of the movement trajectory, preventing the hood from swaying.

[0026] Transparent observation windows 6 are embedded in the side walls of the dust collector hood 4. Inside the dust collector hood 4, a cleaning structure 7 is provided for each observation window 6. The cleaning structure 7 includes a water distribution plate 76, and a water supply pipe 72 is fixed to the base 31 of the grinding structure 3 and connected to the water distribution plate 76, and the water supply pipe 72 is connected to an external cleaning water pipe. A nozzle 71 is integrated on the water distribution plate 76 and faces the inner surface of the observation window 6, used to wet the cleaning cotton 73 so that the cleaning cotton 73 can clean the observation window 6. The cleaning cotton 73 is mounted on the water distribution plate 76 by an elastic mounting bracket 74 that can undergo elastic deformation, and there are no less than two elastic mounting brackets 74, which are evenly distributed on the water distribution plate 76 and are always pressed tightly against the inner surface of the observation window 6 under the action of elastic force. Directly below the cleaning cotton 73, a collection box 75 is installed on the inner wall of the dust collector hood 4.

[0027] With this setup, as the dust collector hood 4 moves upward with the grinding structure 3, the cleaning cotton 73 cleans the observation window 6, ensuring its cleanliness. Water can also be supplied via the water supply pipe 72 to the water distribution plate 76, and then evenly sprayed onto the surface of the observation window 6 by the nozzles 71, wetting the cleaning cotton 73. Subsequently, the displacement structure 2 drives the grinding structure 3 to move up and down, causing the cleaning cotton 73 to perform small reciprocating movements. At this time, under the pressure of the elastic mounting bracket 74, the cleaning cotton 73 wipes the wetted surface of the observation window 6, scraping away dust and dirt. Wastewater and scraped-off dirt drip down into the collection bin 75 below under gravity and are collected uniformly. This structure achieves automated cleaning of the observation window without manual intervention, ensuring visibility during continuous production.

[0028] Furthermore, the dust hood 4 has four openings, each with a groove and a soft sealing curtain 8 on its outer side. The soft sealing curtain 8 can seal the gaps to the maximum extent without interfering with the movement of the workpiece and the grinding head, preventing dust from escaping. At the same time, its softness also avoids hard collisions with the workpiece. In addition, multiple casters 9 are installed around the bottom perimeter of the dust hood 4.

[0029] Furthermore, the bottom of the dust hood 4 is equipped with casters 9, which provide auxiliary support for the dust hood 4, making it smoother when moving up and down with cushioning, reducing friction and interference with the workpiece on the worktable 1, and enhancing the adaptability of the equipment.

[0030] Furthermore, vacuum cleaners 10 are installed on both the front and rear sides of the dust cover 4. The vacuum cleaners 10 are connected to external dust removal pipes, and the vacuum cleaners 10 can extract the dust inside the dust cover 4 during the polishing process.

[0031] In use: Fix the refractory blank onto the worktable 1 and start the external dust removal system. Drive the displacement structure 2 through the control system, which in turn moves the grinding structure 3 and the dust hood 4 to the processing position for grinding. Dust is efficiently captured by the moving dust hood 4, and the dust is extracted from the dust hood 4 by the vacuum cleaner 10 during the grinding process.

[0032] As the dust collector hood 4 rises with the grinding structure 3, the cleaning cotton 73 cleans the observation window 6, ensuring its cleanliness. Water is also supplied to the water distribution plate 76 via the water supply pipe 72 and sprayed evenly onto the surface of the observation window 6 by the nozzles 71, wetting the cleaning cotton 73. Subsequently, the displacement structure 2 drives the grinding structure 3 to move up and down, causing the cleaning cotton 73 to perform small reciprocating movements. Under the pressure of the elastic mounting bracket 74, the cleaning cotton 73 wipes the wetted surface of the observation window 6, scraping away dust and dirt. Wastewater and scraped-off dirt drip into the collection bin 75 below under gravity and are collected uniformly.
