Description

Technical Field

[0001] The invention relates to the technical field of coating production, in particular to a horizontal sand mill for producing coatings. Background Art

[0002] Paint is a liquid or paste-like substance that is applied to the surface of an object to form a protective, decorative, or functional film. It is usually composed of resins, pigments, solvents, and additives. It is mainly applied to the surface of an object by brushing, spraying, dipping, and other methods. A sand grinder is a device used to grind and disperse materials in liquid systems such as paints, inks, and cosmetics. It is usually used to process high-viscosity, low-viscosity, and slurries that require high uniformity.

[0003] In the production process of paint, a sand mill is needed to refine pigment and filler particles and disperse them into a liquid medium. It uses high-speed rotating grinding media to produce strong friction and collision with liquid materials, thereby refining and dispersing solid particles into tiny particles, improving the stability, quality and production efficiency of the paint. It is an indispensable equipment in the paint production process.

[0004] However, the existing sand mill has the following shortcomings:

[0005] 1) During use, the sand mill in the prior art filters and discharges the exhaust gas generated by grinding the paint by water cooling, which cannot completely remove all toxic gases, especially some volatile or water-insoluble toxic gases, resulting in the exhaust gas failing to meet environmental protection standards, reducing the air quality nearby and posing a safety hazard. In addition, the mechanism is fixed by bolts, which need to be removed with tools for maintenance, increasing the difficulty of maintaining the exhaust mechanism.

[0006] 2) When cleaning impurities adhering to the filter screen on the discharge housing or replacing sand beads, it is necessary to use tools to remove the bolts from the discharge housing, and then remove the discharge housing to clean the filter screen or replace the sand beads. The operation is cumbersome, inconvenient for cleaning the filter screen, and increases the workload of the staff;

[0007] 3) When the sand mill in the prior art is in use, the stirring rod drives the sand beads to rotate, and due to the effect of gravity, the sand beads are easily accumulated at the bottom of the inner cylinder, affecting the grinding effect of the sand beads on the material. In addition, impurities are easily adhered to the inner wall of the inner cylinder, and they cannot be rinsed clean by clean water alone, which makes it inconvenient to clean the inner cylinder.

[0008] Therefore, we propose a horizontal sand mill for producing coatings in order to solve the problems raised above. Summary of the Invention

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. The present invention realizes a wider range of gas purification functions and faster maintenance work through the arrangement of a fixed seat, a cooling pipe, a vent, a fixed cylinder, an exhaust net, a support frame, an activated carbon filter layer, an activated alumina filter layer, a receiving groove, a spring, a block, a slot, a connecting rod and a pressing ring. First, the gas flows to the fixed cylinder through the vent, and the gas is cooled by the coolant flowing through the cooling pipe in the fixed seat. Then, the gas passes through the activated carbon filter layer and the activated alumina filter layer on the support frame to complete the filtration and purification. Then, the gas is discharged through the exhaust net on the fixed cylinder, so that the gas passes through multiple layers of filtration while being cooled, and different types of harmful gases can be purified. When the fixed cylinder needs to be removed for maintenance, due to the two groups When the pressing ring is in a separated state when the fixed cylinder is limited by the block, the pressing ring is then pressed from both sides toward the middle to drive the connecting rod and the block to move horizontally on the inner side of the slide groove, so that when the block is away from the slot, the two sets of pressing rings are in a merged state and the block drives the spring to be compressed. Then the fixed cylinder can be taken out of the fixed seat, and then the support frame is taken out of the fixed cylinder, and then the fixed cylinder can be maintained. Similarly, the fixed cylinder can be put back in place by pressing the pressing ring, and then the pressing ring can be released, so that the block is inserted into the slot by the reset of the spring, thereby completing the limiting of the fixed cylinder and the fixed seat, reducing the maintenance difficulty of the exhaust mechanism, and avoiding the problem that all toxic gases cannot be removed and the exhaust mechanism is difficult to maintain in the prior art.

[0022] 2. The present invention is provided with a limit block, a sealing ring, a placement groove, a fixed rod, a dial block, a torsion spring, an insertion rod, a support block and a slide rod, which realizes a simpler cleaning work. First, the slide rod is driven to move inside the support block by dialing the dial block, and the dial block is supported by the fixed rod. Then, the insertion rod is driven away from the insertion hole by the dial block. Then, the discharge shell can be removed to clean the filter screen or remove the sand beads inside the inner cylinder for replacement. After the cleaning is completed, the dial block needs to be dialed and the limit block on the discharge shell is aligned with the limit groove and inserted. Then, the dial block is released and the torsion spring is used to keep it downward. The force drives the shift block and the insertion rod to be inserted into the insertion hole, and the moving path of the shift block is limited by the support block and the sliding rod, so that the lateral vibration force generated by the operation of the sand mill is blocked by the support block. Since the support block is arc-shaped, the longitudinal vibration force generated by the operation of the sand mill cannot affect the arc-shaped moving path of the shift block, so that the stability of the discharge shell is improved, and the sealing ring can increase the sealing performance of the joint between the discharge shell and the inner cylinder, which facilitates the cleaning of the filter screen and improves the situation in the prior art where tools are needed to remove the discharge shell and then clean the filter screen or replace the sand beads.

[0023] 3. The present invention is provided with a placement plate, a mounting ring, a placement block, an arc-shaped scraper, a mounting hole, a threaded rod and a turning handle, which realizes a more efficient cleaning and grinding effect. First, the stirring frame and the arc-shaped scraper are rotated by a driving motor, and clean water is added through the feed pipe. Then, the impurities adhering to the inner wall of the inner cylinder are scraped by the arc-shaped scraper, and then the waste water is discharged through the filter screen and the discharge pipe, thereby completing the cleaning of the inner cylinder. When the arc-shaped scraper is seriously worn and needs to be replaced, the threaded rod can be driven away from the mounting hole by the turning handle, and then the mounting ring is removed and the placement block and the arc-shaped scraper in the movable groove of the placement plate are removed for replacement, and then the replaced arc-shaped scraper is passed through the filter screen. The scraper is inserted into the inner side of the placement plate through the movable groove, and then the mounting ring is moved back to its original position, and the placement plate is engaged with the placement block, so that the two ends of the arc scraper are respectively against the inner sides of the placement plate and the placement block, and then the threaded rod is driven to be inserted into the mounting hole by the turning handle, thereby completing the position limitation of the mounting ring, which provides convenience for the replacement of the arc scraper. During the operation of the sand mill, the arc scraper is driven by the stirring frame to scrape the inner wall of the inner cylinder and at the same time drive the sand beads accumulated at the bottom to roll, so that the sand beads and the stirring rod shear and grind the material, reducing the material adhering to the inner wall of the inner cylinder, and solving the problem in the prior art that the sand beads are easily accumulated at the bottom of the inner cylinder and impurities are easily adhered to the inner wall of the inner cylinder during cleaning.

[0039] The effect achieved by the entire embodiment 2 is: it realizes a simpler cleaning work, first by toggling the toggle block 405 to drive the slide rod 409 to move inside the support block 408, and the toggle block 405 is supported by the fixed rod 404, and then the toggle block 405 drives the insertion rod 407 away from the insertion hole, and then the discharge shell 107 can be removed, the filter screen can be cleaned or the sand beads inside the inner cylinder 104 can be removed and replaced. After the cleaning is completed, the toggle block 405 needs to be toggled, and the limit block 401 on the discharge shell 107 is aligned with the limit groove and inserted, and then the toggle block 405 is released, and then the torsion spring 406 is always used to The downward force drives the shift block 405 and the insertion rod 407 to be inserted into the socket, and the moving path of the shift block 405 is limited by the support block 408 and the slide rod 409, so that the lateral vibration force generated by the operation of the sand mill is blocked by the support block 408. Since the support block 408 is arc-shaped, the longitudinal vibration force generated by the operation of the sand mill cannot affect the arc-shaped moving path of the shift block 405, so that the stability of the discharge shell 107 is improved, and the sealing performance of the joint between the discharge shell 107 and the inner cylinder 104 can be increased by the sealing ring 402, which facilitates the cleaning of the filter screen and reduces the workload of the staff.

[0040] Example 3, according to Figure 3 、 Figure 8 and Figure 9 As shown, the scraping mechanism 5 includes a placement plate 501, which is fixedly mounted on the surface of the stirring frame 109. The outer surface of the stirring frame 109 is slidably connected to a mounting ring 502. A placement block 503 is fixedly mounted on one end of the outer surface of the mounting ring 502. The placement block 503 is snap-fitted to the placement plate 501, and the inner surfaces of the placement block 503 and the placement plate 501 are both provided with a movable groove. The inner side of the movable groove is slidably connected to an arc-shaped scraper 504, and the arc-shaped scraper 504 fits against the inner wall of the inner cylinder 104. The outer surfaces of the stirring frame 109 and the mounting ring 502 are both provided with a mounting hole 505. The inner side of the mounting hole 505 is rotatably connected to a threaded rod 506, and a turning handle 507 is fixedly mounted on one end of the outer surface of the threaded rod 506.

[0041] The effect achieved by the entire embodiment 3 is: achieving a more efficient cleaning and grinding effect, firstly, the stirring frame 109 and the arc scraper 504 are driven to rotate by the driving motor 103, and clean water is added through the feed pipe 106, and then the impurities adhering to the inner wall of the inner cylinder 104 are scraped by the arc scraper 504, and then the waste water is discharged through the filter screen and the discharge pipe 108, thereby completing the cleaning of the inner cylinder 104. When the arc scraper 504 is severely worn and needs to be replaced, the threaded rod 506 can be driven away from the mounting hole 505 by the turning handle 507, and then the mounting ring 502 is removed and the arc scraper 504 in the movable groove on the placement block 503 and the placement plate 501 is removed for replacement, and then the replaced one is removed. The arc scraper 504 is inserted into the inner side of the placement plate 501 through the movable groove, and then the mounting ring 502 is moved back to its original position, and the placement plate 501 is engaged with the placement block 503, so that the two ends of the arc scraper 504 are respectively against the inner sides of the placement plate 501 and the placement block 503, and then the threaded rod 506 is driven to be inserted into the mounting hole 505 by the turning handle 507, thereby completing the position limitation of the mounting ring 502, which provides convenience for the replacement of the arc scraper 504. During the operation of the sand mill, the arc scraper 504 is driven by the stirring frame 109 to scrape the inner wall of the inner cylinder 104 while driving the sand beads accumulated at the bottom to roll, so that the sand beads and the stirring rod shear and grind the material, reducing the material adhering to the inner wall of the inner cylinder 104.

[0042] The working principle of the entire equipment is as follows: when using the sand mill, the material is first fed into the inner side of the inner cylinder 104 through the feed pipe 106, and then the turntable and the transmission belt are driven to rotate by the drive motor 103, so that the turntable on the drive motor 103 drives the turntable on the stirring frame 109 to rotate, and then the stirring frame 109 is driven by the turntable to rotate, so that the stirring frame 109 drives the stirring rod to rotate, and then the stirring frame 109 drives the arc scraper 504 to scrape the inner wall of the inner cylinder 104 while driving the sand beads accumulated at the bottom to roll, so that the sand beads and the stirring rod shear and grind the material, preventing the sand beads from accumulating at the bottom of the inner cylinder 104 and affecting the grinding effect of the material, and reducing the material adhering to the inner wall of the inner cylinder 104. During the grinding process of the material, the cooling liquid flowing through the cooling pipe 202 in the outer cylinder 105 can be used to cool the inner cylinder 104 to prevent the normal use of the sand mill from being affected by excessive temperature. The gas generated during the grinding process can be discharged through the vent 203, and then the gas will flow to the fixed cylinder 204 and cool the gas through the cooling liquid flowing through the cooling pipe 202 in the fixed seat 201. Then the gas will pass through the activated carbon filter layer 207 and the activated alumina filter layer 208 on the support frame 206 to complete the filtration and purification. Then the gas will be discharged through the exhaust net 205 on the fixed cylinder 204, so that the gas passes through multiple layers of filtration while cooling, which can purify different types of harmful gases. When the fixed cylinder 204 needs to be removed, When the locking nut 303 is released, the locking nut 304 is unlocked and the locking nut 305 is unlocked, and the locking nut 303 is unlocked, so that the locking nut 303 is unlocked and the locking nut 305 is unlocked. The spring 302 is reset and inserted into the card slot 304, thereby completing the limit of the fixed cylinder 204 and the fixed seat 201, reducing the maintenance difficulty of the exhaust mechanism 2, and then the ground material can flow to the discharge pipe 108 through the gap at the filter screen on the discharge shell 107, and be discharged through the discharge pipe 108, while the filter screen can block the sand beads to prevent them from flowing out with the material. When it is necessary to clean the impurities adhering to the filter screen or replace the sand beads, the sliding rod 409 can be driven to move on the inner side of the support block 408 by toggling the toggle block 405, and the toggle block 405 is supported by the fixed rod 404, and then the insertion rod 407 is driven away from the insertion hole by the toggle block 405, and then the discharge shell 107 can be removed.The filter screen can be cleaned or the sand beads inside the inner cylinder 104 can be removed for replacement. After cleaning, the shift block 405 needs to be moved and the limit block 401 on the discharge shell 107 needs to be aligned with the limit slot and inserted. Then, the shift block 405 is released. Subsequently, the downward force of the torsion spring 406 drives the shift block 405 and the insertion rod 407 to be inserted into the insertion hole, and the moving path of the shift block 405 is limited by the support block 408 and the slide bar 409, so that the lateral vibration force generated by the operation of the sand mill is blocked by the support block 408. Since the support block 408 is arc-shaped, the longitudinal vibration force generated by the operation of the sand mill cannot affect the arc-shaped moving path of the shift block 405, so that the stability of the discharge shell 107 is improved, and the sealing ring 402 can increase the sealing performance of the joint between the discharge shell 107 and the inner cylinder 104, which is convenient for cleaning the filter screen. When the inner cylinder 104 needs to be cleaned, it can be rinsed by adding clean water through the feed pipe 106, and then the driving motor 103 drives the stirring frame 109 and the arc-shaped scraper to move. The plate 504 rotates and scrapes the impurities adhering to the inner wall of the inner cylinder 104 through the curved scraper 504, and then the waste water is discharged through the filter screen and the discharge pipe 108, thereby completing the cleaning of the inner cylinder 104. When the curved scraper 504 is seriously worn and needs to be replaced, the discharge shell 107 can be removed, and then the threaded rod 506 is driven away from the mounting hole 505 by turning the handle 507, and then the mounting ring 502 can be removed and the placement block 503 and the curved scraper 506 on the placement plate 501 can be placed. 04 is removed for replacement, and then the replaced curved scraper 504 is inserted into the inner side of the placement plate 501 through the movable slot. Then the mounting ring 502 is moved back to its original position and the placement plate 501 is engaged with the placement block 503, so that the two ends of the curved scraper 504 respectively abut against the inner sides of the placement plate 501 and the placement block 503. Then, the threaded rod 506 is driven by the turning handle 507 to insert into the mounting hole 505, thereby completing the position limit of the mounting ring 502, making it convenient to replace the curved scraper 504.
