Description

Technical Field

[0001] The invention relates to the technical field of impurity cleaning devices, and more specifically to an impurity cleaning device for processing filter paperboard. Background Art

[0002] Filter paperboard is a flat or thin material designed for filtering purposes. It is mainly made of cellulose materials such as wood pulp through a wet papermaking process. It has a loose porous structure and good air permeability. It is widely used in food and beverage, pharmaceuticals, chemicals and other industries to efficiently remove impurities and solid particles from various liquids to ensure the purity and quality of the product.

[0003] An impurity cleaning device is required when making filter paperboard. First, the raw materials used to make the filter paperboard are properly pretreated, and the raw materials are crushed, stirred and diluted to facilitate the subsequent separation of impurities. Then, larger impurities are separated through a coarse screen, and multi-stage filtration is used. The screening equipment is usually equipped with screens of different apertures to remove impurities of different sizes. Finally, bleaching agents and flocculants are added to remove organic impurities, and the pH value is adjusted to improve the dispersion of the fibers to combine the pulp together.

[0004] The shortcomings of the existing impurity cleaning device for filter paperboard processing: First: After the raw materials are crushed, a screen is needed to separate the raw materials to remove impurities in the raw materials. When the screen is in use, some holes in the screen plate are often blocked due to the presence of large particles such as fiber bundles and sand in the raw materials, as well as the flow rate of the raw materials. When the holes in the screen plate are blocked, the filtration speed will drop significantly, the pressure will increase, and the production efficiency will be affected. In order to solve the problem of screen plate blockage, the screen needs to be disassembled and cleaned.

[0005] Second: In the process of removing impurities, due to the lack of precision in the collection and pretreatment of the original materials, metal debris and tiny impurities will exist in the raw materials, which will eventually lead to uneven surface, spots or hard spots on the product, which not only affects the appearance and printing quality, but also affects the strength of the paper.

[0014] Technical effects and advantages of the present invention: 1. The present invention starts the second motor to make the first gear start to rotate in order to quickly screen out suitable fine materials. When the first gear starts to rotate, the second gear starts to be active. When the second gear rotates, the transmission rod starts to rotate and makes the flat top blocks on both sides rotate. When the flat top blocks rotate, the eccentric columns that deviate from the circle start to move. The push rod is connected to the eccentric column so that the movement trajectory of the push rod is up and down. The filter screen is connected to the push rod through the connecting column, which makes the filter screen bump up and down to quickly screen the material, making it easier to separate particles of different sizes, thereby achieving a better screening effect, which is conducive to making the quality and particle size of the final product of the filter paperboard meet the requirements.

[0015] 2. The present invention places the raw materials of the filter paperboard into the crushing box and transmits them to the iron removal device through the first conveyor belt. At this time, the first motor is started to rotate the transmission roller. When the transmission roller starts to rotate, the belt installed on the surface of the transmission roller starts to rotate. At this time, the permanent magnet placed inside the belt starts to work, and the iron scraps and other metal impurities on the first conveyor belt are adsorbed on the belt. The metal impurities on the belt can be separated by the setting of the separation block, so that these impurities will not accumulate or stick together during the operation of the belt. With the rotation of the belt, the metal impurities will move to one side of the iron removal device, and one side of the iron removal device is a non-magnetic area. At this time, the metal impurities fall into the collection box under the action of gravity, which can effectively solve the problems caused by metal scraps and tiny impurities in the original materials and improve the appearance of the product.

[0016] 3. In the present invention, when the holes in the screen are clogged or the aperture of the screen needs to be adjusted, the telescopic rod of the pneumatic cylinder is started to move to one side, and the first driving rod is affected by the telescopic rod to move to one side, and the second driving rod drives the movable plate to move to one side, and the transmission block starts to move under the action of the fixed pin, and the movable pin is connected to the block, so that the adjustment block is folded on the fixed bar to adjust the size of the screen aperture, so that the filtered bulk material will be discharged through the filter residue outlet, which is conducive to quickly clearing the blockage through the action of the telescopic rod of the pneumatic cylinder when the holes of the screen are clogged, ensuring the continuity of the screening process, and at the same time, according to the size of the impurities in the raw material, the aperture of the screen can be conveniently adjusted, making the screening process more efficient and reducing the retention time of the material on the screen.

[0031] The working principle of the present invention is as follows: the raw materials of the filter cardboard are placed in the crushing box 1 and transmitted to the iron removal device 2 through the first conveyor belt 101. At this time, the first motor 203 is started to make the transmission roller 204 start to rotate. When the transmission roller 204 starts to rotate, the belt 205 installed on its surface starts to rotate. At this time, the permanent magnet 207 placed inside the belt 205 starts to work, and the iron filings and other metal impurities on the crushed materials of the first conveyor belt 101 are adsorbed on the belt 205. The metal impurities on the belt 205 can be separated by the setting of the partition block 206, so that these impurities will not accumulate or stick to each other during the operation of the belt 205. Together, with the rotation of the belt 205, the metal impurities will move to one side of the iron removal device 2, and one side of the iron removal device 2 is a non-magnetic area.

At this time, the first driving rod 303 is affected by the telescopic rod 302 and moves to one side. At this time, the second driving rod 304 drives the movable plate 305 to move to one side. At this time, the transmission block 306 starts to move under the action of the fixed pin 3061, and the movable pin 3062 is connected to the block 307. The adjusting block 308 is then folded on the fixing bar 1042 to adjust the size of the screen aperture, so that the filtered bulk material is discharged through the filter residue outlet 105, which is beneficial for quickly clearing the blockage through the action of the telescopic rod 302 of the pneumatic cylinder 301 when the holes of the screen are blocked, thereby ensuring the continuity of the screening process. At the same time, the aperture of the screen can be easily adjusted according to the size of impurities in the raw material, making the screening process more efficient and reducing the retention time of the material on the screen. In order to quickly screen out suitable fine materials, the second motor 402 is started to make the first gear 403 start to rotate. When the first gear 40 3 starts to rotate, the second gear 404 starts to take the initiative, when the second gear 404 rotates, the transmission rod 405 starts to rotate and makes the flat top blocks 4051 on both sides rotate, and when the flat top blocks 4051 rotate, the eccentric column 4052 deviating from the circle starts to move, and the push rod 406 is connected with the eccentric column 4052 so that the movement trajectory of the push rod 406 is up and down, and the filter screen 408 is connected with the push rod 406 through the connecting column 407, so that the filter screen 408 bumps up and down to quickly screen the material, and the raw materials screened by the screen continue to fall to the second conveyor belt 106 after being filtered by the screening mechanism 4 to continue to complete the subsequent work.
