At the same time, the discharged material is prone to clogging the discharge pipe.
[0004] In view of this, we propose a color mixing kettle for easy material discharge in chemical coating production. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.
[0024] Please see Figure 1 - Figure 4 As shown, this embodiment provides a color mixing kettle for easy material discharge in chemical coating production, including a color mixing kettle body 1, a cover 2 provided on the upper surface of the color mixing kettle body 1, an air inlet pipe 3 for introducing nitrogen into the color mixing kettle body 1 connected to the upper surface of the cover 2, an air inlet valve 4 for opening and closing the air inlet pipe 3 provided on the air inlet pipe 3, a pressure gauge 5 fixedly installed on the upper surface of the cover 2, and a discharge pipe 6 connected to the lower end of the color mixing kettle body 1.
[0025] A mixing shaft 7 is rotatably connected inside the color mixing tank body 1, and a cleaning component for processing the material on the inner wall of the color mixing tank body 1 is fixedly installed on the outer wall of the mixing shaft 7.
[0026] The cleaning assembly includes at least a plurality of C-shaped fixing rods 8, which are arranged in a ring array outside the mixing shaft 7. The two ends of the plurality of C-shaped fixing rods 8 are respectively fixedly connected to the upper and lower outer walls of the mixing shaft 7. A cleaning sleeve 9 is movably sleeved on the outside of the plurality of C-shaped fixing rods 8. A cleaning brush 10 and a scraper 11 are respectively fixedly connected to the outer wall of the cleaning sleeve 9. Threaded holes for installing positioning screws 12 are opened inside the cleaning sleeve 9 and the C-shaped fixing rods 8.
[0027] The lower end of the mixing rod is fixedly connected to two scrapers 13 that are adapted to the bottom of the color mixing tank body 1.
[0028] The working principle is as follows: During use, chemical coatings are placed into the color mixing tank body 1 for mixing and color adjustment. When the mixing shaft 7 rotates, it drives multiple C-shaped fixing rods 8 to rotate. At this time, the scraper 11 on the outside of the cleaning sleeve 9 scrapes and cleans the inner wall of the color mixing tank body 1, thereby preventing material from sticking to the wall and ensuring uniform color adjustment of the coating. When discharging after color adjustment, the scraper 11 on the outside of the cleaning sleeve 9 and the two scrapers 13 at the bottom of the mixing shaft 7 can scrape off the coating adhering to the inner wall of the color mixing tank body 1, reducing coating waste and facilitating discharge. During discharge, the air inlet valve 4 can be opened to introduce nitrogen into the color mixing tank body 1 through the air inlet pipe 3. The air pressure inside the color mixing tank body 1 is increased by the pressure gauge 5, which ensures the stability of the air pressure inside the color mixing tank body 1. This allows for efficient discharge through pneumatic discharge, ensuring that any undischarged material inside the tank can be discharged smoothly from the discharge pipe 6, preventing paint from clogging the discharge pipe 6. When it is necessary to clean the inner wall of the color mixing tank body 1, the positioning screw 12 can be rotated to release the restriction on the position of the cleaning sleeve 9. This allows the cleaning sleeve 9 to be rotated so that the side of the cleaning sleeve 9 with the cleaning brush 10 faces the inner wall of the color mixing tank body 1. Thus, when the U-shaped fixing rod 8 rotates, the cleaning brush 10 can clean the inner wall of the color mixing tank body 1.
[0029] To ensure the mixing effect of the chemical coating, multiple stirring rods 14 are fixedly connected to the upper end of the outer wall of the mixing shaft 7, and an auger 15 is fixedly installed at the lower end of the outer wall of the mixing shaft 7. Reinforcing rods 16 are fixedly connected to the upper surfaces of the two scrapers 13, and the upper ends of the two reinforcing rods 16 are fixedly connected to the lower surfaces of the two stirring rods 14 respectively. When in use, the mixing shaft 7 rotates, which allows the multiple stirring rods 14 to stir and mix the chemical coating in the color mixing tank body 1. The auger 15 can transport the chemical coating at the bottom of the color mixing tank body 1 when the mixing shaft 7 rotates forward and reverse, thereby driving the chemical coating at the bottom of the color mixing tank body 1 to move upward, ensuring the color mixing effect of the coating. When discharging the color-mixed chemical coating, it can drive the chemical coating inside the color mixing tank body 1 to move downward, increasing the discharge effect of the chemical coating. The use of stirring rods 14 and auger 15 together ensures the uniformity of color mixing of the chemical coating.
[0030] Considering the need to ensure the stability of the mixing shaft 7 during rotation, a motor is fixedly installed on the upper surface of the cover 2. The output end of the motor is fixedly connected to the upper end of the mixing shaft 7. A support frame 17 is fixedly connected to the inner wall of the cover 2. The outer wall of the mixing shaft 7 is rotatably connected to the inner wall of the support frame 17. When in use, the motor is started, which can drive the mixing shaft 7 to rotate. Under the action of the support frame 17, the rotation of the mixing shaft 7 can be restricted, thereby ensuring the stability of the mixing shaft 7 during rotation.
[0031] To facilitate pressure relief when the gas pressure inside the color mixing tank body 1 is too high, a one-way valve 18 is fixedly installed on the air inlet pipe 3. The one-way valve 18 is located below the air inlet valve 4. The upper end of the cover body 2 is connected to a pressure relief pipe 19, and a pressure relief valve 20 is fixedly installed on the pressure relief pipe 19. When the color mixing tank body 1 is processing chemical coatings and the gas pressure inside the color mixing tank body 1 is too high, the pressure relief valve 20 can be activated to allow the internal gas to be discharged through the pressure relief pipe 19, preventing potential safety hazards.
[0032] To ensure the stability of the color mixing tank body 1 during operation, a support platform 21 is provided at the lower end of the color mixing tank body 1. Multiple support blocks 22 are fixedly connected to the lower end of the outer wall of the color mixing tank body 1. The lower surfaces of the multiple support blocks 22 all abut against the upper surface of the support platform 21. The upper surface of the support platform 21 is provided with an installation groove that matches the lower end of the color mixing tank body 1. The end of the discharge pipe 6 away from the color mixing tank body 1 passes through the support platform 21 and extends to the outside of the support platform 21. A discharge valve 23 is provided on the discharge pipe 6. During use, the color mixing tank body 1 is supported by the support platform 21, and the multiple support blocks 22 can increase the stability of the color mixing tank body 1 on the support platform 21. The support platform 21 can provide an installation position for the discharge pipe 6, and the discharge valve 23 on the discharge pipe 6 can conveniently control the discharge of the processed chemical coating from the discharge pipe 6.
[0033] In addition, it is necessary to ensure the sealing effect at the connection between the cover 2 and the color mixing vessel body 1. Therefore, a sealing groove for installing the sealing ring 24 is opened on the lower surface of the cover 2. The lower surface of the sealing ring 24 abuts against the upper surface of the color mixing vessel body 1. A manhole 25 is opened at the upper end of the cover 2. A sealing cover 26 is hinged to the upper end of the manhole 25. The upper end of the cover 2 is connected to the feed pipe 27. A feed valve 28 is fixedly installed on the feed pipe 27. By setting the sealing ring 24, the connection between the cover 2 and the color mixing vessel body 1 can be sealed, thereby ensuring the increased effect when pressurized through the air inlet pipe 3. The feed pipe 27 facilitates the addition of chemical raw materials to be processed into the color mixing vessel body 1, and the feed valve 28 facilitates the control of the feed amount.
