Description

Technical Field

[0001] This utility model relates to the technical field of paint mixing cans, and in particular to a water-based paint mixing can that facilitates the cleaning of residue. Background Technology

[0002] Water-based coatings are typically mixed using a mixing tank. However, after the water-based coating is discharged from the mixing tank, residues easily remain on the inner and bottom walls of the tank. Chinese utility model patent CN222093043U discloses a water-based coating mixing tank that allows visualization of the coating's state. This tank includes a tank body, with an inlet fixedly connected to the top and an outlet fixedly connected to the bottom. This invention utilizes the rotation of a stirring shaft to achieve the movement of a first conical tooth on the stirring shaft. Under the action of the first cone tooth, the four sets of second cone teeth rotate simultaneously, causing the first rotating rod to drive the third cone tooth to rotate. The fourth cone tooth rotates under the action of the third cone tooth, causing the second rotating rod to drive the second stirring rod to rotate. This achieves the effect of stirring the water-based coating through the second stirring rod, which can enhance the stirring force of the water-based coating and improve the stirring effect. At the same time, the second stirring rod and the first stirring rod are staggered, which makes the stirring of the water-based coating more thorough, and thus the water-based coating can be better blended.

[0003] The aforementioned paint mixing tank uses a vertically arranged scraper structure to scrape off the residual water-based paint inside the tank. However, it cannot efficiently push the water-based paint hanging on the wall downwards, resulting in low efficiency in removing residual water-based paint from the wall. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a water-based paint mixing tank that is easy to clean by pushing the water-based paint hanging on the wall downwards, thereby improving the efficiency of residual discharge of water-based paint.

[0005] This utility model discloses a water-based paint mixing tank for easy cleaning of residue, comprising a frame, a tank body, and a discharge pipe. The tank body is mounted on the frame, and a mixing chamber is provided inside the tank body. An inlet communicating with the mixing chamber is located at the upper end of the frame, and a discharge pipe communicating with the bottom of the mixing chamber is installed at the bottom of the frame. It also includes a slide rail, a magnet, an annular scraper, an inner magnetic block, and a stirring mechanism. The slide rail is vertically mounted on the outer wall of the tank body, and the magnet is vertically mounted on the slide rail. The annular scraper is located in the mixing chamber of the tank body, and its outer edge scrapes against the inner wall of the tank body. An inner magnetic block is installed in the annular scraper, and the inner magnetic block and the magnet are magnetically connected through the side wall of the tank body. The stirring mechanism is used to stir the water-based paint in the mixing chamber of the tank body. To improve the magnetic stability between the magnet and the inner magnetic block... For this design, the tank body is preferably made of non-magnetic stainless steel, such as austenitic stainless steel, and has a 3-stage exhaust pipe. During operation, the water-based paint is fed into the mixing chamber of the tank. The stirring mechanism thoroughly mixes the water-based paint. After the water-based paint is mixed, the valve of the discharge pipe is opened to discharge it. A lifting assembly for the magnet is installed on the frame. The lifting assembly drives the magnet to move downward from the top of the tank. The magnetic attraction between the magnet and the inner magnetic block drives the annular scraper to descend. Under the scraping action of the annular scraper, the residual material hanging on the inner wall of the tank is scraped and pushed downward, causing the residual material to gather in the discharge pipe and be discharged. Compared with the existing technology that uses a horizontally arranged scraper structure to scrape off the residual water-based paint in the tank, this method can efficiently push the water-based paint hanging on the wall downward, improving the discharge efficiency of the water-based paint residue.

[0006] Preferably, the stirring mechanism includes a cross frame, a motor, a stirring rod, and multiple stirring blades. The cross frame is mounted on a machine frame and is located above the tank. The motor is mounted on the cross frame, and the output shaft of the motor is connected to the upper end of the stirring rod. The stirring rod is rotatably connected to the cross frame, and the lower part of the stirring rod extends into the paint mixing chamber of the tank. Multiple stirring blades are mounted on the lower part of the stirring rod. The motor drives the stirring rod and multiple stirring blades to rotate, and the multiple stirring blades stir the water-based paint in the tank, so that the water-based paint is fully mixed.

[0007] Preferably, it also includes an inner liner, an inner tube, and a pressure plate. The inner liner is fitted inside the paint mixing chamber of the tank. An inner tube is installed at the bottom of the inner liner and extends into the discharge pipe. The pressure plate is installed on the pick-up and drop-off port of the tank by bolts. The pressure plate presses and fixes the upper end of the inner liner to the pick-up and drop-off port of the tank. A ring scraper scrapes the inner surface of the inner liner, which can form a hydrophobic layer on the inner surface of the inner liner. The inner liner is fitted inside the paint mixing chamber of the tank and placed on the inner wall of the tank to isolate the tank from the water-based paint and reduce the residue of water-based paint. The water-based paint is discharged through the inner tube and the discharge pipe. The inner liner is replaced after a period of operation.

[0008] Preferably, it also includes an air extraction pipe, which is installed on the tank body and is connected to the paint mixing chamber of the tank body; the air extraction pipe is connected to an external air pump, and when the inner liner is installed into the paint mixing chamber of the tank body, air is extracted through the air extraction pipe to make the inner liner adhere to the inner wall of the tank body.

[0009] Preferably, it also includes a pusher cylinder, one end of which is connected to the frame and the other end to the crossbar. The lower end of the stirring rod is rotatably connected to the bottom of the inner liner. When cleaning the residue on the inner surface of the inner liner, the pusher cylinder pushes the crossbar upward, causing the crossbar to lift the motor, stirring rod, and multiple stirring blades. The stirring rod lifts the bottom of the inner liner above the loading and unloading port of the tank through rotating connecting parts such as bearing seats, so that the inner surface of the inner liner flips outward, thus facilitating the cleaning of residue. To improve the outward flipping effect of the inner liner, a motor lifting assembly can be installed on the crossbar to achieve two-stage lifting.

[0010] Preferably, it also includes a residue trough and a slag discharge trough. The residue trough is installed on the upper outer wall of the tank body, and the slag discharge trough is installed on one side of the residue trough. When the inner liner is lifted and turned outward, the water-based coating remaining on the inner liner is cleaned into the residue trough and discharged through the slag discharge trough, thereby improving the residue cleaning efficiency.

[0011] Preferably, it also includes an upper mounting ring and an annular scraper II. The upper mounting ring is installed above the loading and unloading port of the tank body, and the annular scraper II is provided on the inner edge of the upper mounting ring. The annular scraper II scrapes the outer surface of the inner liner. The annular scraper II is installed above the loading and unloading port of the tank body through the upper mounting ring. During the process of the inner liner being lifted and turned outward, the inner surface of the inner liner is scraped by the annular scraper II, thereby cleaning the residual material on the inner surface of the inner liner.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: In order to improve the magnetic attraction stability between the magnet and the inner magnetic block, the tank body is preferably made of non-magnetic stainless steel (such as austenitic stainless steel, 3 exhaust pipes, etc.). During operation, the water-based paint is input into the paint mixing chamber of the tank body. The stirring mechanism runs to fully stir and mix the water-based paint. After the water-based paint is mixed, the valve of the discharge pipe is opened to discharge it. The lifting component of the magnet is set on the frame. The lifting component drives the magnet to move downward from the top of the tank body. Thus, the magnetic attraction between the magnet and the inner magnetic block drives the annular scraper to descend. Under the scraping action of the annular scraper, the wall residue on the inner wall of the tank body is scraped and pushed downward, so that the wall residue gathers towards the discharge pipe and is discharged. Compared with the prior art, which uses a horizontally arranged scraper structure to scrape off the water-based paint residue in the tank, this method can efficiently push the wall residue water-based paint downward and improve the discharge efficiency of water-based paint residue.

[0015] To facilitate understanding of this utility model, a more complete description will be given below with reference to the accompanying drawings. This utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to make the disclosure of this utility model more thorough and complete. Example 1

[0016] like Figures 1 to 4 and Figure 7As shown, a water-based paint mixing tank for easy cleaning of residue includes a frame 1, a tank body 2, and a discharge pipe 3. The tank body 2 is mounted on the frame 1, and a mixing chamber is provided inside the tank body 2. An inlet communicating with the mixing chamber is provided at the upper end of the frame 1, and a discharge pipe 3 communicating with the bottom of the mixing chamber is installed at the bottom of the frame 1. It also includes a slide rail 4, a magnet 5, an annular scraper 6, an inner magnetic block 7, and a stirring mechanism. The slide rail 4 is vertically mounted on the outer wall of the tank body 2, and the magnet 5 is vertically mounted on the slide rail 4. The annular scraper 6 is located in the mixing chamber of the tank body 2, and the outer edge of the annular scraper 6 scrapes against the inner wall of the tank body 2. The inner magnetic block 7 is installed in the annular scraper 6. The inner magnetic block 7 and the magnet 5 are magnetically connected through the side wall of the tank 2. The stirring mechanism is used to stir the water-based paint in the paint mixing chamber of the tank 2. The stirring mechanism includes a cross frame 8, a motor 9, a stirring rod 10 and multiple stirring blades 11. The cross frame 8 is installed on the frame 1 and is located above the tank 2. The motor 9 is installed on the cross frame 8. The output shaft of the motor 9 is connected to the upper end of the stirring rod 10. The stirring rod 10 is rotatably connected to the cross frame 8. The lower part of the stirring rod 10 extends into the paint mixing chamber of the tank 2. Multiple stirring blades 11 are installed on the lower part of the stirring rod 10.

[0017] To improve the magnetic attraction stability between magnet 5 and inner magnetic block 7, tank 2 is preferably made of non-magnetic stainless steel, such as austenitic stainless steel, and includes components like slide rail 4 and exhaust pipe 16. During operation, water-based paint is fed into the mixing chamber of tank 2. Motor 9 drives stirring rod 10 and multiple stirring blades 11 to rotate. The stirring blades 11 stir the water-based paint in tank 2, ensuring thorough mixing. After mixing, the valve of discharge pipe 3 is opened to discharge the paint. The lifting assembly of magnet 5 is mounted on frame 1 (see diagram). Not shown, the lifting assembly drives the magnet 5 to move downward from the top of the tank 2. The magnetic attraction between the magnet 5 and the inner magnetic block 7 drives the annular scraper 6 to descend. Under the scraping action of the annular scraper 6, the wall residue on the inner wall of the tank 2 is scraped and pushed downward, so that the wall residue gathers and is discharged from the discharge pipe 3. Compared with the existing technology that uses a horizontally arranged scraper structure to scrape off the water-based paint residue in the tank, this method can efficiently push the wall-mounted water-based paint downward, improving the discharge efficiency of water-based paint residue. Example 2

[0018] like Figure 1 , Figure 3 and Figure 6 As shown, based on Embodiment 1, it also includes an inner liner 13, an inner tube 14, and a pressure plate 15. The inner liner 13 is fitted into the paint mixing chamber of the tank body 2. The inner tube 14 is provided at the bottom of the inner liner 13 and extends into the discharge pipe 3. The pressure plate 15 is installed on the pick-up and drop-off port of the tank body 2 by bolts. The pressure plate 15 presses and fixes the upper end of the inner liner 13 to the pick-up and drop-off port of the tank body 2. It also includes an air extraction pipe 16, which is installed on the tank body 2 and communicates with the paint mixing chamber of the tank body 2.

[0019] The suction pipe 16 is connected to an external suction pump. After the inner liner 13 is installed in the paint mixing chamber of the tank 2, air is drawn through the suction pipe 16 to make the inner liner 13 adhere to the inner wall of the tank 2. At this time, the annular scraper 6 scrapes the inner surface of the inner liner 13, which can set a hydrophobic layer on the inner surface of the inner liner 13. The inner liner 13 is installed in the paint mixing chamber of the tank 2 and is placed on the inner wall of the tank 2 to isolate the tank 2 from the water-based paint and reduce the residue of the water-based paint. The water-based paint is discharged through the inner pipe 14 and the discharge pipe 3. After working for a period of time, the pressure plate 15 is removed and the inner liner 13 is replaced. Example 3

[0020] like Figure 1 , Figure 3 , Figure 4 and Figure 5 As shown, based on Embodiment 2, it also includes a push cylinder 12, one end of which is connected to the frame 1, and the other end of which is connected to the crossbar 8. The lower end of the stirring rod 10 is rotatably connected to the bottom of the inner liner 13. It also includes a residual material trough 17 and a slag discharge trough 18. The residual material trough 17 is installed on the upper outer wall of the tank body 2, and the slag discharge trough 18 is installed on one side of the residual material trough 17. It also includes an upper mounting ring 19 and an annular scraper 20. The upper mounting ring 19 is installed above the loading and unloading port of the tank body 2, and the annular scraper 20 is provided on the inner edge of the upper mounting ring 19. The annular scraper 20 scrapes the outer surface of the inner liner 13.

[0021] When cleaning the residue on the inner surface of the inner liner 13, the push cylinder 12 pushes the crossbeam 8 upward, causing the crossbeam 8 to drive the motor 9, stirring rod 10 and multiple stirring blades 11 to rise. The stirring rod 10 lifts the bottom of the inner liner 13 above the loading and unloading port of the tank 2 through rotating connecting parts such as bearing seats, causing the inner surface of the inner liner 13 to turn outward. The second annular scraper 20 is installed above the loading and unloading port of the tank 2 through the upper mounting ring 19. During the process of the inner liner 13 being lifted and turned outward, the inner surface of the inner liner 13 is scraped by the second annular scraper 20, thereby cleaning the residue on the inner surface of the inner liner 13. The water-based paint remaining on the inner liner 13 is cleaned into the residue trough 17 for collection and discharged through the slag discharge trough 18, improving the residue cleaning efficiency. In order to improve the outward turning effect of the inner liner 13, a lifting assembly of the motor 9 can be set on the crossbeam 8 (not shown in the figure) to realize two-stage lifting.

[0022] like Figures 1 to 7As shown, this utility model discloses a water-based paint mixing tank that facilitates the cleaning of residue. During operation, the water-based paint is first fed into the mixing chamber 13 of the tank body 2. The motor 9 drives the stirring rod 10 and multiple stirring blades 11 to rotate. The stirring blades 11 stir the water-based paint in the tank body 2, ensuring thorough mixing. After mixing, the water-based paint is discharged through the inner pipe 14 and the discharge pipe 3. Then, the lifting assembly drives the magnet 5 to move downwards from the top of the tank body 2. The magnetic attraction between the magnet 5 and the inner magnetic block 7 causes the annular scraper 6 to descend. Under the scraping action of the annular scraper 6, the residue adhering to the inner wall of the inner liner 13 is scraped downwards. The scraper pushes the residual material hanging on the wall to gather in the inner pipe 14 and the discharge pipe 3 and then discharge it. After working for a period of time, the pusher cylinder 12 pushes the cross frame 8 upward, which causes the cross frame 8 to drive the motor 9, the stirring rod 10 and multiple stirring blades 11 to rise. The stirring rod 10 lifts the bottom of the inner liner 13 above the loading and unloading port of the tank body 2 through rotating connecting parts such as bearing seats, so that the inner surface of the inner liner 13 turns outward. During the process of the inner liner 13 being lifted and turned outward, the inner surface of the inner liner 13 is scraped by the annular scraper 20, thereby cleaning off the residual material on the inner surface of the inner liner 13. Finally, the cleaned-off water-based paint is collected through the residue tank 17 and discharged through the slag discharge tank 18.

[0023] The main functions achieved by this utility model are: 1. The horizontally arranged scraper structure scrapes off the residual water-based paint in the tank, which can efficiently push the water-based paint hanging on the wall downwards and improve the discharge efficiency of water-based paint residue. 2. The inner liner 13 isolates the tank body 2 from the water-based coating, reducing water-based coating residue; 3. It can efficiently clean and drain water-based paint residue on the inner wall of the inner liner 13.

[0024] This utility model discloses a water-based paint mixing tank that facilitates the cleaning of residues. Its installation, connection, or setting methods are all common mechanical methods, and any method that can achieve its beneficial effect can be implemented. The tank body 2, discharge pipe 3, slide rail 4, magnet 5, annular scraper 6, inner magnetic block 7, motor 9, stirring rod 10, stirring blade 11, push cylinder 12, inner liner 13, pressure plate 15, exhaust pipe 16, residue trough 17, slag discharge trough 18, upper mounting ring 19, and annular scraper 20 of this utility model are commercially available.
