Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of paint production, in particular to a horizontal sand mill for producing paint. BACKGROUND

[0002] Paint is a liquid or paste material coated on the surface of an object to form a protective, decorative, functional film, usually composed of resin, pigment, solvent and additives, etc. It is mainly applied to the surface of the object by brushing, spraying, dipping, etc. A sand mill is a device used for grinding and dispersing materials in liquid systems such as paint, ink and cosmetics. It is usually used to process high-viscosity, low-viscosity and high-uniformity slurry.

[0003] In the production process of paint, a sand mill is needed to refine and disperse pigment and filler particles into a liquid medium. It refines and disperses solid particles into small particles through the friction and collision of high-speed rotating grinding media and liquid materials, thereby improving the stability, quality and production efficiency of the paint. It is an indispensable device in the production process of paint.

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

[0005] 1) In the existing sand mill, the exhaust gas generated during the grinding of paint is filtered and discharged by water cooling. However, it cannot completely remove all toxic gases, especially some volatile or water-insoluble toxic gases, resulting in exhaust gas that does not meet environmental standards, reducing the air quality near the device, and having safety hazards. The device is fixed by bolts, which need to be removed with tools during maintenance, increasing the maintenance difficulty of the exhaust device.

[0006] 2) When cleaning or replacing the impurities on the filter screen attached to the discharge shell, the bolts need to be removed from the discharge shell with tools, and then the discharge shell needs to be removed to clean or replace the sand beads. The operation is complicated, inconvenient for cleaning the filter screen, and increases the workload of the workers.

[0007] 3) In the existing sand mill, the stirring rod drives the sand beads to rotate, which is prone to accumulate at the bottom of the inner cylinder due to gravity, affecting the grinding effect of the sand beads on the material. In addition, impurities are easily attached to the inner wall of the inner cylinder, which cannot be washed clean with water, making it inconvenient to clean the inner cylinder.

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

[0021] 1. The application realizes more extensive gas purification function and faster maintenance work, the gas flows to the fixed cylinder through the ventilation opening, and the cooling liquid flowing through the cooling pipe in the fixed seat cools the gas, then the gas passes through the active carbon filter layer and the active alumina filter layer on the support frame to complete the filtration and purification, and then the gas is discharged through the exhaust net on the fixed cylinder, so that the gas is cooled and filtered at the same time, and different types of harmful gas can be purified, when the fixed cylinder needs to be removed for maintenance, the two groups of pressing rings are in a separated state when limiting the fixed cylinder through the clamping block, then press the pressing ring from both sides to the middle to drive the connecting rod and the clamping block to translate in the inner side of the sliding groove, so that the two groups of pressing rings are in a combined state when the clamping block is away from the clamping groove, and the spring is compressed through the clamping block, then the fixed cylinder can be taken out from the fixed seat, then the support frame is taken out from the fixed cylinder, then the fixed cylinder can be maintained, similarly, the fixed cylinder can be put back to the original position by pressing the pressing ring, then the clamping block is inserted into the clamping groove through the reset of the spring, so that the limiting of the fixed cylinder and the fixed seat is completed, the maintenance difficulty of the exhaust mechanism is reduced, and the problems that all toxic gases cannot be removed and the exhaust mechanism maintenance difficulty is high in the prior art are avoided.

[0022] 2. The application sets the limiting block, the sealing ring, the placing groove, the fixed rod, the pushing block, the torsional spring, the inserting rod, the supporting block and the sliding rod, realizes more convenient cleaning work, first moves the sliding rod in the inner side of the supporting block by pushing the pushing block, and supports the pushing block through the fixed rod, then drives the inserting rod away from the insertion hole through the pushing block, then the discharge shell can be taken off, the filter screen is cleaned or the sand beads inside the inner cylinder are taken off for replacement, after cleaning, the limiting block on the discharge shell is inserted into the limiting groove by pushing the pushing block, then the pushing block is loosened, then the pushing block and the inserting rod are inserted into the insertion hole through the downward force of the torsional spring, and the movement path of the pushing block is limited by the supporting block and the sliding rod, so that the transverse vibration force generated by the operation of the sand mill is blocked by the supporting block, the longitudinal vibration force generated by the operation of the sand mill cannot affect the arc-shaped movement path of the pushing block, so that the stability of the discharge shell is improved, and the sealing property of the abutting place of the discharge shell and the inner cylinder is increased through the sealing ring, which facilitates the cleaning work of the filter screen, and improves the situation that the discharge shell needs to be taken off with the help of tools to clean or replace the sand beads in the prior art.

[0023] 3. This invention incorporates a placement plate, mounting ring, placement block, arc-shaped scraper, mounting hole, threaded rod, and rotary handle, achieving more efficient cleaning and grinding effects. First, a drive motor rotates the stirring frame and arc-shaped scraper, while clean water is added through the feed pipe. Then, the arc-shaped scraper scrapes away impurities adhering to the inner wall of the inner cylinder. Wastewater is then discharged through a filter screen and discharge pipe, completing the cleaning of the inner cylinder. When the arc-shaped scraper is severely worn and needs replacement, the rotary handle moves the threaded rod away from the mounting hole. The mounting ring is then removed, and the arc-shaped scraper in the moving groove on the placement block and placement plate is removed for replacement. Finally, the replaced arc-shaped scraper is... The installation ring is inserted into the inner side of the placement plate through the moving groove, and then moved back to its original position, so that the placement plate and the placement block are engaged, so that the two ends of the arc-shaped scraper abut against the inner side of the placement plate and the placement block respectively.

This solves the problem in the prior art that sand droplets are easy to accumulate at the bottom of the inner cylinder and that impurities are easy to adhere to the inner wall of the inner cylinder during cleaning.

[0035] Please see the appendix Figure 1 -Appendix Figure 9 As shown, the present invention provides a technical solution: a horizontal sand mill for producing coatings, comprising a body 1, the body 1 including a base 101, a transmission box 102 fixedly installed at the top of the base 101, an inner cylinder 104 and an outer cylinder 105 installed on one side of the outer surface of the transmission box 102, an exhaust mechanism 2 and a clamping mechanism 3 installed on the outer surface of the outer cylinder 105, and a limit mechanism 4 and a scraping mechanism 5 respectively installed on one end of the outer surface and the inner surface of the inner cylinder 104.

[0036] Example 1, according to Figures 1-5As shown, a drive motor 103 is installed on one side of the outer surface of the transmission box 102. A feed pipe 106 is fixedly installed on the outer surface of the inner cylinder 104, and a discharge shell 107 is installed at one end of the outer surface of the inner cylinder 104. A discharge pipe 108 is fixedly installed at one end of the outer surface of the discharge shell 107. A stirring frame 109 is installed on one side of the outer surface of the transmission box 102, and a grinding roller 110 is fixedly installed on the outer surface of the stirring frame 109. The exhaust mechanism 2 includes a fixed seat 201, which is fixedly installed on the outer surface of the outer cylinder 105. Cooling pipes 202 are installed on the inner surfaces of both the outer cylinder 105 and the fixed seat 201. Ventilation openings 203 are provided on the surfaces of the inner cylinder 104, the outer cylinder 105, and the fixed seat 201. A fixed cylinder 204 is slidably connected to the inner side of the ventilation opening 203. An exhaust screen 205 is fixedly installed at the top of the fixed cylinder 204, and a support frame 206 is slidably connected to the inner side of the fixed cylinder 204. An activated carbon filter layer 207 and an activated alumina filter layer 208 are installed on the inner side of 206. The output ends of the stirring rack 109 and the drive motor 103 are both installed on the turntable inside the transmission box 102. The outer surfaces of the two turntables are rotatably connected to the transmission belt. The clamping mechanism 3 includes a storage groove 301, which is opened on the top surface of the fixed cylinder 204. A spring 302 is fixedly installed on one end of the inner surface of the storage groove 301 opposite to the opening. A locking block 303 is fixedly installed on one end of the outer surface of the spring 302. A locking groove 304 is opened on the inner surface of the fixed base 201. The locking block 303 is slidably connected to the inner side of the locking groove 304. A connecting rod 305 is fixedly installed on the top of the locking block 303. A pressing ring 306 is fixedly installed on the top of the connecting rod 305. A sliding groove is opened on the inner side of the storage groove 301 and the top of the fixed cylinder 204. The locking block 303 and the connecting rod 305 are slidably connected to the inner side of the sliding groove.

[0037] The overall effect of Embodiment 1 is as follows: it achieves a wider range of gas purification functions and faster maintenance. First, the gas flows to the fixed cylinder 204 through the vent 203, and is cooled by the coolant flowing through the cooling pipe 202 inside the fixed seat 201. Then, the gas passes through the activated carbon filter layer 207 and the activated alumina filter layer 208 on the support frame 206 for filtration and purification. Subsequently, the gas is discharged through the exhaust net 205 on the fixed cylinder 204. This allows the gas to pass through multiple layers of filtration while being cooled, purifying different types of harmful gases and improving the air quality in the vicinity. When the fixed cylinder 204 needs to be removed for maintenance, the two sets of pressing rings 306 are separated when the fixed cylinder 204 is limited by the locking block 303. In the first position, press the pressing ring 306 from both sides towards the middle to move the connecting rod 305 and the locking block 303 to move inside the slide groove. When the locking block 303 is away from the slot 304, the two sets of pressing rings 306 are in a combined state. The locking block 303 drives the spring 302 to compress, and then the fixed cylinder 204 can be removed from the fixed seat 201. Then the support frame 206 can be removed from the fixed cylinder 204. Then the fixed cylinder 204 can be maintained. Similarly, the fixed cylinder 204 can be put back into its original position by pressing the pressing ring 306, and then the pressing ring 306 can be released, so that the locking block 303 is inserted into the slot 304 by the reset of the spring 302, thereby completing the limiting of the fixed cylinder 204 and the fixed seat 201, reducing the maintenance difficulty of the exhaust mechanism 2.

[0038] Example 2, according to Figure 3 , Figure 6 and Figure 7 As shown, the limiting mechanism 4 includes a limiting block 401, which is fixedly installed on one end of the outer surface of the discharge shell 107. A limiting groove is formed on one end of the outer surface of the inner cylinder 104. The limiting block 401 is slidably connected to the inner side of the limiting groove. A sealing ring 402 is fixedly installed on one end of the outer surface of the inner cylinder 104. The sealing ring 402 is sleeved on the outer surface of the discharge shell 107. A filter screen is installed on one end of the outer surface of the discharge shell 107. A placement groove 403 is formed on the inner cylinder 104 near the outer surface of the discharge shell 107. A fixing rod 4 is fixedly installed on the inner side of the placement groove 403. 04. A toggle block 405 is rotatably connected to the outer surface of the fixed rod 404. Torsion springs 406 are fixedly installed on both sides of the outer surface of the toggle block 405 and both sides of the inner surface of the placement groove 403. An insertion rod 407 is fixedly installed at the bottom end of the toggle block 405. Insertion holes are opened on the surfaces of the inner cylinder 104 and the placement groove 403. The insertion rod 407 is slidably connected to the inner side of the insertion hole. Support blocks 408 are fixedly installed on both sides of the inner surface of the placement groove 403. Sliding rods 409 are slidably connected to the inner sides of the two sets of support blocks 408. The sliding rods 409 are fixedly installed on the outer surface of the toggle block 405.

[0039] The overall effect of Embodiment 2 is as follows: it achieves a simpler cleaning process. First, by moving the lever 405, the slide bar 409 moves inside the support block 408, and the lever 405 is supported by the fixing rod 404. Then, the lever 405 moves the insertion rod 407 away from the insertion hole, and then the discharge shell 107 can be removed to clean the filter screen or remove and replace the sand beads inside the inner cylinder 104. After cleaning, the lever 405 needs to be moved, and the limiting block 401 on the discharge shell 107 is aligned with the limiting groove and inserted. Then, the lever 405 is released, and then the torsion spring 406 keeps the filter screen in place. The downward force drives the push block 405 and the insertion rod 407 into the insertion hole. The support block 408 and the slide rod 409 limit the movement path of the push block 405, 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 movement path of the push block 405, thereby improving the stability of the discharge shell 107. The sealing ring 402 can increase the sealing at the joint between the discharge shell 107 and the inner cylinder 104, 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 installed on the surface of the stirring rack 109. An installation ring 502 is slidably connected to the outer surface of the stirring rack 109. A placement block 503 is fixedly installed at one end of the outer surface of the installation ring 502. The placement block 503 is engaged with the placement plate 501. Moving grooves are provided on the inner surfaces of both the placement block 503 and the placement plate 501. An arc-shaped scraper 504 is slidably connected to the inner side of the moving groove. The arc-shaped scraper 504 is in contact with the inner wall of the inner cylinder 104. Installation holes 505 are provided on the outer surfaces of both the stirring rack 109 and the installation ring 502. A threaded rod 506 is rotatably connected to the inner side of the installation hole 505. A handle 507 is fixedly installed at one end of the outer surface of the threaded rod 506.

[0041] The overall effect of Embodiment 3 is as follows: it achieves more efficient cleaning and grinding. First, the drive motor 103 drives the stirring frame 109 and the arc-shaped scraper 504 to rotate, and clean water is added through the feed pipe 106. Then, the arc-shaped scraper 504 scrapes the impurities adhering to the inner wall of the inner cylinder 104. Next, the wastewater is discharged through the filter screen and the discharge pipe 108, thereby completing the cleaning of the inner cylinder 104. When the arc-shaped scraper 504 is severely worn and needs to be replaced, the screw rod 506 can be moved away from the mounting hole 505 by the throttle 507. Then, the mounting ring 502 is removed, and the arc-shaped scraper 504 in the moving groove on the placement block 503 and the placement plate 501 is removed and replaced. Then, the replaced scraper is placed in the groove. The arc-shaped scraper 504 is inserted into the inner side of the placement plate 501 through the moving groove. Then, the mounting ring 502 is moved back to its original position, and the placement plate 501 is engaged with the placement block 503. This allows the two ends of the arc-shaped scraper 504 to abut against the inner sides of the placement plate 501 and the placement block 503, respectively. Then, the screw rod 506 is inserted into the mounting hole 505 by the throttle 507, thereby limiting the position of the mounting ring 502 and making it convenient to replace the arc-shaped scraper 504. During the operation of the sand mill, the arc-shaped 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. This causes the sand beads and the stirring rod to 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: During the operation of the sand mill, the material is first fed into the inner cylinder 104 through the feed pipe 106. Then, the drive motor 103 drives the turntable and transmission belt to rotate, causing the turntable on the drive motor 103 to drive the turntable on the mixing frame 109 to rotate. Next, the turntable drives the mixing frame 109 to rotate, causing the mixing frame 109 to drive the mixing rod to rotate. Subsequently, the mixing frame 109 drives the arc scraper 504 to scrape against the inner wall of the inner cylinder 104, while simultaneously causing the sand beads accumulated at the bottom to roll. This allows the sand beads and the mixing rod to 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 amount of material adhering to the inner wall of the inner cylinder 104. During the grinding process, the inner cylinder 104 can be cooled by the coolant flowing through the cooling pipe 202 inside the outer cylinder 105, preventing excessive temperature from affecting the normal operation of the sand mill. The gas generated during grinding can be discharged through the vent 203, then flows to the fixed cylinder 204, where it is cooled by the coolant flowing through the cooling pipe 202 inside the fixed seat 201. The gas then passes through the activated carbon filter layer 207 and the activated alumina filter layer 208 on the support frame 206 for filtration and purification. Finally, the gas is discharged through the exhaust net 205 on the fixed cylinder 204. This multi-layer filtration process, where the gas is cooled, purifies different types of harmful gases. When it is necessary to remove the fixed cylinder 204... 04. When performing maintenance, since the two sets of pressing rings 306 are in a separated state when the locking block 303 limits the fixed cylinder 204, pressing the pressing rings 306 from both sides towards the middle causes the connecting rod 305 and the locking block 303 to move horizontally inside the slide groove. When the locking block 303 is away from the slot 304, the two sets of pressing rings 306 are in a combined state, and the locking block 303 drives the spring 302 to compress. Then the fixed cylinder 204 can be removed from the fixed seat 201. Next, the support frame 206 can be removed from the fixed cylinder 204, and then the fixed cylinder 204 can be maintained. Similarly, the fixed cylinder 204 can be returned to its original position by pressing the pressing ring 306, and then the pressing ring 306 can be released, causing the locking block 303 to... The spring 302 resets and inserts into the slot 304, thus limiting the positioning of the fixed cylinder 204 and the fixed seat 201, reducing the maintenance difficulty of the exhaust mechanism 2. The ground material then flows through the gap in the filter screen on the discharge shell 107 to the discharge pipe 108, where it is discharged. The filter screen blocks the sand beads, preventing 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 lever 405 is moved by the lever 405, causing the slide rod 409 to move inside the support block 408. The lever 405 is supported by the fixed rod 404. The lever 405 then moves the insertion rod 407 away from the insertion hole, allowing the discharge shell 107 to be removed.Clean the filter screen or remove and replace the sand beads inside the inner cylinder 104. After cleaning, move the dial block 405 and align the limiting block 401 on the discharge shell 107 with the limiting groove. Then release the dial block 405. Subsequently, the downward force of the torsion spring 406 drives the dial block 405 and the insertion rod 407 into the insertion hole. The support block 408 and the slide rod 409 limit the movement path of the dial block 405, so that the lateral vibration force generated by the operation of the sand mill is blocked by the support block 408. Because the support block 408 is arc-shaped, the longitudinal vibration force generated by the operation of the sand mill cannot affect the arc-shaped movement path of the pusher block 405, thus improving the stability of the discharge shell 107. The sealing ring 402 also increases the sealing at the joint between the discharge shell 107 and the inner cylinder 104, facilitating the cleaning of the filter screen. When the inner cylinder 104 needs cleaning, clean water can be added through the feed pipe 106 for rinsing, and then the drive motor 103 will drive the stirring frame 109 and the arc-shaped scraper... The plate 504 rotates, and the arc-shaped scraper 504 scrapes the impurities adhering to the inner wall of the inner cylinder 104. Then, the wastewater is discharged through the filter screen and the discharge pipe 108, thus completing the cleaning of the inner cylinder 104. When the arc-shaped scraper 504 is severely worn and needs to be replaced, the discharge shell 107 can be removed. Then, the screw rod 506 is moved away from the mounting hole 505 by the handle 507. Then, the mounting ring 502 can be removed, and the placement block 503 is placed on the arc-shaped scraper 504 on the placement plate 501. 04. Remove and replace the old curved scraper 504. Insert the new curved scraper 504 into the inner side of the placement plate 501 through the moving slot. Then move the mounting ring 502 back to its original position, and engage the placement plate 501 with the placement block 503. This ensures that both ends of the curved scraper 504 abut against the inner sides of the placement plate 501 and the placement block 503, respectively. Then, use the handle 507 to drive the threaded rod 506 into the mounting hole 505, thus limiting the position of the mounting ring 502 and facilitating the replacement of the curved scraper 504.
