Description

Technical Field

[0001] This utility model relates to the field of sillimanite brick production technology, specifically a sillimanite brick cutting device for tin bath top cover. Background Technology

[0002] Sillimanite bricks are a type of high-grade refractory material made primarily from natural sillimanite minerals (such as sillimanite, andalusite, and kyanite). They are characterized by their transformation into mullite and free silica at high temperatures, resulting in excellent high-temperature resistance (refractory temperature 1770–1830℃), low thermal expansion coefficient, thermal shock resistance, and resistance to slag and molten glass erosion. Sillimanite bricks are typically produced using high-temperature firing or slurry casting methods. Mullite, corundum powder, and zirconium oxide are often added to the raw materials to enhance their properties. After production, sillimanite bricks require cutting equipment for final preparation.

[0003] For example, patent announcement number CN112140363B provides an adjustable precision stone brick cutting device that can adjust the size of the stone brick cut, eliminates the need for manual pushing of the stone brick, and achieves high cutting efficiency. An adjustable precision stone brick cutting device includes: a base with a first support plate symmetrically arranged on the top of the base; N-shaped blocks symmetrically arranged on the top of the base; a moving cutting device arranged between the upper parts of the N-shaped blocks; and a feeding device arranged on the top of the base. By activating a servo motor, the first rotating shaft is rotated. Then, with the cooperation of the moving cutting device and the feeding device, the stone brick is cut quickly, thereby improving work efficiency. Furthermore, this device is simple to operate, making it easy for users to use.

[0004] Because the special material of stone bricks easily generates dust when the cutting device is used, the cutting device in the above technology is not equipped with a dust collection mechanism, which causes the cutting dust to escape into the environment and pollute the working environment; therefore, the market urgently needs to develop a silicon wire stone brick cutting device for tin bath top cover to help people solve the existing problems.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] Please see Figure 1-4This utility model provides an embodiment of a sillimanite brick cutting device for tin bath top covers, comprising a cutting table 1, a support mesh 101 fixedly connected to the middle of the upper end face of the cutting table 1, and a cutting mechanism 102 connected to the middle of the upper end face of the cutting table 1. The sillimanite brick to be cut is fixed to the upper end of the support mesh 101 and then cut by the cutting mechanism 102. An air suction hood 2 is fixedly connected inside the cutting table 1 and to the lower end of the support mesh 101. A rectangular air duct 201 is fixedly connected to the middle of the lower end of the air suction hood 2. A rectangular connecting ring 204 is fixedly connected to the lower end of the outer wall of the rectangular air duct 201. A receiving box 3 is provided at the lower end of the rectangular air duct 201. C-shaped cutters are fixedly connected to the upper ends of both sides of the receiving box 3. Two C-shaped cross-section connecting strips 301 are inserted into the middle of the rectangular connecting ring 204 on both sides. A circular suction pipe 202 is fixedly connected to one side of the rectangular air duct 201. One side of the circular suction pipe 202 extends out of the end face of the cutting table 1 and is connected to the dust collection box 4. A suction fan 203 is fixedly installed on the circular suction pipe 202. The suction fan 203 draws air from the inside of the suction hood 2 through the circular suction pipe 202, making the inside of the suction hood 2 a negative pressure state. The suction hood 2 draws dust generated by the cutting of silicon wire stone slabs through the support net 101 and conveys it to the dust collection box 4. Larger dust particles fall to the collection box 3 by gravity when passing through the rectangular air duct 201.

[0020] Please see Figure 2 and Figure 4 A dust removal port 405 is provided on one side of the dust collector 4. A partition 401 is fixedly connected to the lower middle part of the interior of the dust collector 4. A circular air outlet 402 is provided in the middle of the upper surface of the dust collector 4. A barrel-shaped filter screen 5 is provided in the middle of the upper part of the partition 401. The upper end of the barrel-shaped filter screen 5 and the lower end of the circular air outlet 402 on the upper surface of the interior of the dust collector 4 are rotatably connected by a bearing 403. A blowpipe 502 is fixedly provided on one side of the interior of the barrel-shaped filter screen 5. Multiple blow nozzles 503 are evenly spaced on the end face of the blowpipe 502 adjacent to the inner wall of the barrel-shaped filter screen 5. The upper end of the blowpipe 502... An air pump 504 is fixedly connected to the circular air outlet 402. After the dust-laden airflow enters the dust collection box 4, it is filtered through the barrel-shaped filter screen 5 and discharged upward through the circular air outlet 402 from the inside of the barrel-shaped filter screen 5. The barrel-shaped filter screen 5 rotates synchronously when filtering dust, and centrifugal force prevents a large amount of dust from being adsorbed on the outer wall of the barrel-shaped filter screen 5. At the same time, the air pump 504 supplies air to the blow pipe 502. Multiple blow nozzles 503 on the blow pipe 502 spray the inner wall of the barrel-shaped filter screen 5 in the opposite direction when the barrel-shaped filter screen 5 rotates, so that the dust attached to the outer wall of the barrel-shaped filter screen 5 can be effectively removed.

[0021] Please see Figure 4Inside the dust collector 4, a drive motor 404 is fixedly installed at the lower middle of the partition 401. A rotating shaft 501 is fixedly connected to the lower middle of the barrel-shaped filter screen 5. The lower end of the rotating shaft 501 passes through the partition 401 and is fixedly connected to the output shaft of the drive motor 404. The drive motor 404 drives the barrel-shaped filter screen 5 to rotate slowly.

[0022] Working Principle: During use, the sillimanite brick to be cut is fixed on the upper end of the support net 101, and the cutting mechanism 102 performs the cutting operation. Dust generated during the cutting process is drawn into the suction hood 2 through the support net 101 under the negative pressure of the suction fan 203, and then transported to the dust collection box 4 through the rectangular air duct 201 and the circular suction pipe 202. After entering the dust collection box 4, the dust-laden airflow first passes through the rotating barrel-shaped filter 5 for filtration, and the filtered clean air is discharged from the circular air outlet 402. During this process, the drive motor 404 drives the barrel-shaped filter 5 to rotate slowly and continuously, using centrifugal force to prevent dust accumulation; simultaneously, the air pump 504 performs pulse-style reverse blowing on the inner wall of the barrel-shaped filter 5 through the nozzle 503 on the blowpipe 502, causing the attached dust to fall to the bottom of the partition 401, and finally be collected and cleaned through the dust removal port 405. Larger dust particles fall directly into the collection box 3 due to gravity within the rectangular air duct 201, achieving graded collection.

[0023] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
