Description

Technical Field

[0001] The utility model relates to the technical field of calcium carbonate grinding, in particular to a water-based paint modified nano calcium carbonate grinding and filtering device. Background Art

[0002] Nano-calcium carbonate, also known as ultrafine calcium carbonate, is used in water-based and oil-based paints, offering advantages such as fineness, uniformity, high whiteness, and excellent optical properties. Nano-scale ultrafine calcium carbonate exhibits steric hindrance. During paint production, it suspends the denser lithopone in the formulation, preventing sedimentation. The resulting paint film exhibits enhanced whiteness and gloss without compromising hiding power. Nano-calcium carbonate must be ground into a powder. A currently published patent, "A Raw Material Grinding Device for Calcium Carbonate Processing (Publication No.: CN220610777U)," describes a "grinding machine body having a base mounted at its lower end, with a discharge port extending through the base. A screening mechanism is mounted in the middle of the lower end of the base, with the output end of the grinder body extending into the screening mechanism. A connecting pipe is fixedly connected to the middle of the side end of the screening mechanism, and a feeding mechanism is fixedly connected to the other end of the connecting pipe. The feeding mechanism is located in the middle of the side end of the base, and the output end of the feeding mechanism is located in the middle of the side end of the base. The grinding device is located above the main body of the grinder and extends to the inside of the main body of the grinder. The ground calcium carbonate powder can be screened, and the substandard calcium carbonate particles screened out can be sent to the grinder for re-grinding to improve work efficiency. In addition, the grinding device occupies a small area and is easy to use. However, there are still certain defects during use. Among them, the powder is screened by the vibration of the sieve plate. During the long-term screening process, the sieve plate will inevitably be blocked, which will cause the sieve plate to be unable to screen. At this time, manual cleaning is required, which will affect the screening efficiency. For this reason, a water-based paint modified nano calcium carbonate grinding and filtering equipment is proposed. Utility Model Content

Obviously, the embodiments described are only part of the embodiments, not all of the embodiments. Based on the embodiments, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection.

[0022] Example 1:

[0023] See also Figure 1-3 A water-based paint modified nano-calcium carbonate grinding and filtering equipment includes a mounting frame 1, a grinding box 2 is fixedly installed on the upper part of the mounting frame 1, a screening box 3 is installed at the lower part of the grinding box 2, a feed port 4 is opened at the upper part of the grinding box 2, a slider 5 is slidably installed on the inner wall of the screening box 3, a sieve plate 6 is fixedly installed on the outer side of the slider 5, fixed grooves 7 are opened on both sides of the screening box 3, a screw rod 8 is movably installed on the inner wall of the fixed groove 7, a moving block 9 is threadedly installed on the outer side of the screw rod 8, a connecting plate 10 is fixedly installed on the outer side of the moving block 9, a first motor 12 is fixedly installed on the outer side of the screening box 3, and a grinding device is provided inside the grinding box 2.

[0024] Preferably, the output end of the first motor 12 is fixedly connected to the rear end of the screw rod 8, the outer side of the moving block 9 is slidingly connected to the inner wall of the fixed groove 7, and the outer side of the moving block 9 is fixedly installed with a high-pressure blowing plate 11.

[0025] Specifically, nano calcium carbonate enters the grinding box 2 from the feed port 4, and is ground by a grinding device, wherein the grinding device can be selected from existing grinding equipment on the market for grinding as needed. Here, the ground nano calcium carbonate then enters the screening box 3, is screened through the sieve plate 6, and the leak-proof sieve plate 6 is prevented from being blocked. Then, the first motor 12 works, the screw 8 rotates, the first moving block 9 moves with the connecting plate 10, and the connecting plate 10 moves with the high-pressure blowing plate 11, blowing strong wind to the surface of the sieve plate 6 to blow away the powder stuck in the sieve.

[0026] Preferably, a fan 13 is fixedly installed on the outside of the screening box 3 , and an air duct is connected to the outside of the fan 13 , and one end of the air duct is connected to the inside of the high-pressure blowing plate 11 .

[0027] Specifically, the fan 13 transmits wind to the high-pressure blowing plate 11 through the air duct. After the wind is pressurized, the screening plate can be cleaned quickly.

[0028] Preferably, a screening box 18 is fixedly mounted on the front surface of the screening box 3 , and a screening opening 17 is opened on the front side of the screening box 3 .

[0029] Working principle: Nano calcium carbonate is added into the grinding box 2, and the grinding box 2 starts to grind. The ground calcium carbonate powder enters the screening box 3 and will fall onto the sieve plate 6. It will be screened by the sieve plate 6, and then the unqualified calcium carbonate powder after screening will enter the screening box 18 from the screening port 17. When the sieve plate 6 needs to be cleaned, the fan 13 is started to work, and it is connected to the high-pressure blowing plate 11 through the air duct. The high-pressure blowing plate 11 will blow strong wind towards the surface of the sieve plate 6, and then the first motor 12 drives the screw rod 8 to rotate. After the screw rod 8 rotates, the moving block 9 will move, and the moving block 9 will drive the connecting plate 10 to move. The connecting plate 10 drives the high-pressure blowing plate 11 to move, so that the high-pressure blowing plate 11 can carry out comprehensive wind blowing cleaning on the surface of the sieve plate 6. The strong wind force can blow off the powder in the sieve plate 6, thereby avoiding blockage of the sieve plate 6 and improving the screening effect and work efficiency.

A vibration motor 16 is fixedly installed on the lower part of the screen plate 6.

[0032] Specifically, the vibration motor 16 works to make the screen vibrate. During the vibration, the slider 5 can move on the fixed rod 14. The slider 5 will squeeze the spring 15 during the sliding. The deformation of the spring 15 can make the screen plate 6 vibrate up and down, thereby screening the powder.

[0033] Preferably, a feed drum 19 is fixedly installed on the front side of the grinding box 2, a second motor 21 is fixedly installed on the upper end of the feed drum 19, a feed auger 20 is movably installed inside the feed drum 19, and the output end of the second motor 21 is fixedly connected to the upper end of the feed auger 20.

[0034] Specifically, after unqualified powder materials are screened out, the second motor 21 is started to work, driving the feeding auger 20 to rotate, and the feeding auger 20 can transport the powder materials upward.

[0035] Preferably, the outer side of the upper end of the feeding cylinder 19 is connected to a material guide port 22 , and the discharge end of the material guide port 22 is located above the feed port 4 .

[0036] Working principle: During screening, the vibration motor 16 works to make the screening vibrate. During the vibration, the slider 5 can move on the fixed rod 14. The slider 5 will squeeze the spring 15 during sliding. The deformation of the spring 15 can make the screen plate 6 vibrate up and down, thereby screening the powder. Reasonable powder will be screened out, and unqualified powder will enter the screen material. Then start the second motor 21 to work and drive the feed auger 20 to rotate. The feed auger 20 can carry the powder upward, and then the unqualified powder will re-enter the grinding box 2 through the guide port 22 and be ground again, so that the unqualified powder can be quickly sent back into the grinding box 2 for re-grinding, thereby improving the quality of nano calcium carbonate grinding.
