Description

Technical Field

[0001] This utility model relates to the field of mixing mill technology, and in particular to a mill wheel cleaning device. Background Technology

[0002] A mixing mill is a mechanical device used in industrial production to mix raw materials. It is especially needed in the production of refractory bricks. The mixing mill mixes different mineral raw materials such as quartz sand and silica lime in the production of refractory bricks, which facilitates the subsequent production of refractory bricks.

[0003] In the process of mixing raw materials, existing mixing mills, in addition to setting up a rolling mill to crush and mix the raw materials, also have a single scraping mechanism to scrape the raw materials in the device. During the crushing process of the rolling mill, the raw materials are easy to remain on the side wall of the rolling mill, which affects the mixing of the raw materials in the mixing trough. It will also affect the subsequent mixing operation of other raw materials, causing the raw materials remaining on the rolling mill to be added to different mixtures, affecting the production quality of refractory bricks.

[0004] To address this issue, a grinding wheel cleaning device for grinding mills is proposed, which has the advantages of convenient material mixing and grinding wheel cleaning, thereby solving the problems mentioned in the background technology. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a grinding wheel cleaning device for grinding mills.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a grinding wheel cleaning device for a grinding mill, comprising a housing, a drive shaft installed at the center of the bottom of the housing, and a rotating frame fixed to the top of the drive shaft by bolts, two mixing grinding wheels being rolled on two sides of the rotating frame, and two cleaning frames fixed to the top of the rotating frame corresponding to the mixing grinding wheels, one end of the cleaning frame being welded with an inclined scraper in contact with the side of the mixing grinding wheel, and the lower end of the inclined scraper being provided with a slope surface, a vertical plate being welded to the surface of the cleaning frame, and a comb plate being inclinedly welded to the vertical plate, and an arc scraper in contact with the inner wall of the housing being fixed to one end of the comb plate.

[0007] As a further description of the above technical solution: two mounting blocks are welded to one end of the cleaning frame that is in contact with the rotating frame, and the surfaces of the two mounting blocks are respectively fixedly connected to the rotating frame by screws.

[0008] As a further description of the above technical solution: one end of the arc scraper is provided with a cutting surface, and the end of the arc scraper with the cutting surface forms a crescent portion.

[0009] As a further description of the above technical solution: the comb plate and the arc scraper are arranged perpendicularly, and the comb plate and the arc scraper form a scraping structure for the refractory brick raw material.

[0010] As a further description of the above technical solution: the surface of the cleaning frame is welded with a stop block, and the stop block is in contact with the side of the rotating frame.

[0011] As a further description of the above technical solution: a triangular block is welded at the included angle where the vertical plate and the comb plate are connected, and the comb plate is connected to the lower part of the vertical plate.

[0012] This utility model has the following beneficial effects:

[0013] In this invention, a cleaning frame is installed on the top of a square rotating frame, corresponding to each of the two mixing wheels. As the drive shaft drives the rotating frame to rotate, it causes the two mixing wheels to move in a circular motion. At this time, because the inclined scraper on the cleaning frame contacts the side of the rolling mixing wheel with its sloping surface, it is easy to scrape off the refractory brick material remaining on the side of the mixing wheel. Since the vertical plate of the cleaning frame is inclinedly welded with a comb plate, and one end of the comb plate is in close contact with the inner wall of the machine casing through an arc scraper, as the drive shaft drives the rotating frame to rotate, the comb part of the comb plate can comb and mix the crushed refractory brick material. Then, the arc scraper cleans the refractory brick material remaining on the inner wall of the machine casing. While cleaning the inner wall of the machine casing and the mixing wheels, it can also comb and mix the refractory brick material, avoiding the residual material from affecting the subsequent mixing operation of other materials, which is conducive to ensuring the production quality of subsequent refractory bricks.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

[0020] According to an embodiment of the present invention, a grinding wheel cleaning device for a grinding mill is provided.

[0021] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments, such as... Figure 1-3 As shown, a grinding wheel cleaning device for a grinding mill according to an embodiment of the present utility model includes a housing 1. A drive shaft 2 is installed at the center of the bottom of the housing 1, and a rotating frame 3 is fixed to the top of the drive shaft 2 by bolts. Two grinding wheels 4 are rolled on two sides of the rotating frame 3, and two cleaning frames 5 are fixed to the top of the rotating frame 3 corresponding to the grinding wheels 4. An inclined scraper 6 that contacts the side of the grinding wheel 4 is welded to one end of the cleaning frame 5, and a slope surface 12 is provided at the lower end of the inclined scraper 6. A vertical plate 7 is welded to the surface of the cleaning frame 5, and a comb plate 8 is inclinedly welded on the vertical plate 7. An arc scraper 9 that contacts the inner wall of the housing 1 is fixed to one end of the comb plate 8. The housing 1 is the cylindrical shell of the grinding mill. The principle of the grinding mill is an existing known technology, and there are mature products. Therefore, its principle will not be further explained. The driving components and discharge structure of the grinding mill are not shown in the figure. The length of the inclined scraper 6 is greater than the length of the grinding wheel 4, which is beneficial to fully scrape off the residual refractory brick raw materials.

[0022] In one embodiment, two mounting blocks 11 are welded to one end of the cleaning frame 5 that is in contact with the rotating frame 3, and the surfaces of the two mounting blocks 11 are respectively fixedly connected to the rotating frame 3 by screws. With this structure, it is easy to install the cleaning frame 5 securely.

[0023] In one embodiment, one end of the arc scraper 9 is provided with a cutting surface, and the end of the arc scraper 9 with the cutting surface forms a crescent portion. With this structure, it is easy to fully scrape off the refractory brick raw materials remaining on the inner wall of the casing 1 during the rotation of the arc scraper 9.

[0024] In one embodiment, the comb plate 8 and the arc scraper 9 are arranged perpendicularly to each other, and the comb plate 8 and the arc scraper 9 form a scraping structure for refractory brick raw materials. With this structure, the refractory brick raw materials can be scraped and stirred at the same time as the inner wall of the casing 1 is cleaned and the refractory brick raw materials are combed.

[0025] In one embodiment, a stop block 10 is welded to the surface of the cleaning frame 5, and the stop block 10 fits against the side of the rotating frame 3. The setting of the stop block 10 increases the stability of the cleaning frame 5 installation, making it less prone to swaying and displacement during the stress stage.

[0026] In one embodiment, a triangular block is welded to the included angle at the connection between the vertical plate 7 and the comb plate 8. The comb plate 8 is connected to the lower part of the vertical plate 7. The triangular block increases the firmness of the connection between the vertical plate 7 and the comb plate 8. The comb teeth of the comb plate 8 are in contact with the bottom of the inner side of the housing 1.

[0027] Working principle:

[0028] In use, first, the mounting block 11 of the cleaning frame 5 is attached to the top surface of the rotating frame 3, and then fixed with bolts, so that the abutment block 10 of the cleaning frame 5 is in contact with the side of the rotating frame 3, the inclined scraper 6 is in contact with the side of the mixing wheel 4, and the arc scraper 9 is in contact with the inner wall of the casing 1. When the drive component of the mixing mill drives the transmission shaft 2 to rotate, the transmission shaft 2 drives the rotating frame 3 to rotate, causing the rotating frame 3 to drive the two mixing wheels 4 to make circular motion, pressing and mixing the refractory brick raw materials. At this time, because the inclined scraper 6 on the cleaning frame 5 adopts an inclined slope Surface 12 contacts the side of the rolling mixing wheel 4, making it easy to scrape off the refractory brick material remaining on the side of the mixing wheel 4. Since the vertical plate 7 of the cleaning frame 5 is inclinedly welded with a comb plate 8, and one end of the comb plate 8 is in close contact with the inner wall of the machine casing 1 through the arc scraper 9, as the drive shaft 2 drives the rotating frame 3 to rotate, the comb part of the comb plate 8 can comb and mix the crushed refractory brick material. Then the arc scraper 9 cleans the refractory brick material remaining on the inner wall of the machine casing 1, avoiding the residual material from affecting the subsequent mixing operation of other materials.

[0029] 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.
