Description

Technical Field

[0001] The invention relates to the technical field of separation equipment, in particular to a filtering device for producing water-based ink. Background Art

[0002] Water-based ink is a type of ink whose main components are water, pigments, and various auxiliary additives. It has the advantages of being highly environmentally friendly, easy to clean, and brightly colored. It is widely used in printing, calligraphy, and painting. In the production process of ink, impurities may be mixed in due to factors such as insufficient dissolution of pigments, residual additives, dust pollution during transportation, and residues on production equipment. If these impurities are not treated, they will directly affect the printing quality and performance stability of the ink. Therefore, after the production process of the ink, it is necessary to add a decontamination process to remove impurities in the ink.

[0003] At present, the most commonly used treatment method in the ink impurity removal process is the filtration method, which uses a filter that can separate ink and impurities to effectively separate ink and impurities to ensure the purity of the ink. However, when using the filtration method, as the amount of ink processed increases, the impurities accumulated on the filter gradually increase. These impurities will be carried by the ink to various parts of the filter, resulting in an increase in the filter blockage rate and a decrease in separation efficiency, which affects the efficiency of ink impurity removal. Summary of the invention

[0004] In view of the problems existing in the above-mentioned impurity removal treatment method, the present invention proposes a filtering device for water-based ink production that can treat accumulated impurities to prevent them from affecting the filtering function, aiming to improve the processing efficiency of impurity removal treatment for ink.

DETAILED DESCRIPTION

[0040] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Example

[0041] A filtering device for producing water-based ink, see Figure 1-Figure 3 , including: a support base 1; a filter barrel 2 fixedly mounted on the support base 1, the ink is filtered out of impurities in the filter barrel 2, the filter barrel 2 is connected by an upper and lower part of the mounting structure, which is convenient for the internal maintenance of the filter barrel 2; a discharge bucket 3 fixedly mounted at the bottom of the filter barrel 2, the filtered ink is discharged from the discharge bucket 3, so that the ink is collected in a centralized manner; an addition port 4 fixedly mounted on the top of the filter barrel 2, the ink is added to the filter barrel 2 through the addition port 4 to prevent ink leakage; a filter frame 5 slidably mounted at the lower part of the filter barrel 2, the filter frame 5 is used to separate ink and impurities to achieve the purpose of removing impurities from the ink; a rotating shaft 6 rotatably mounted in the filter barrel 2, the rotating shaft 6 is at the filter barrel 2 The center line; a brush plate 7 is fixedly mounted on the bottom of the rotating shaft 6, and the bristles at the bottom of the brush plate 7 are in contact with the filter frame 5. When the brush plate 7 rotates, it can move the impurities gathered on the filter frame 5, and constantly change the position of the impurities, so as to avoid the impurities accumulating on the filter frame 5 for a long time and clogging the filter frame 5; a flow changing frame 8 is fixedly mounted on the rotating shaft 6, and the flow changing frame 8 is inclined. The distance between the lower part and the rotating shaft 6 is greater than the distance between the upper part and the rotating shaft 6. When the flow changing frame 8 rotates, it will drive the impurities to flow upward relative to the ink; a motor 9 is fixedly mounted on the top of the filter barrel 2, and the output end of the motor 9 is fixed to the rotating shaft 6. The motor 9 drives the brush plate 7 and the flow changing frame 8 to rotate through the rotating shaft 6.

[0042] The device is used to remove impurities from ink. First, ink is added into the filter barrel 2. Under the separation effect of the filter frame 5, the ink passes through the filter frame 5. In a unit time, the flow rate of the ink passing through the filter frame 5 will be much smaller than the amount of ink added. Therefore, after adding a proper amount of ink into the filter barrel 2, the addition of ink can be stopped. It is only necessary to wait for the ink to pass through the filter frame 5 for filtering impurities.

[0043] During the impurity removal process of the ink, the motor 9 is started to control the brush plate 7 and the flow-changing frame 8 to rotate. When the brush plate 7 rotates, the impurities intercepted and separated by the filter frame 5 are moved to make the impurities leave the filter frame 5, so as to prevent some impurities from being carried by the flowing ink to move in the direction of the filter frame 5, and to prevent these impurities from clogging the mesh of the filter frame 5 or even passing through the mesh; and when the flow-changing frame 8 rotates, the inclined design of the flow-changing frame 8 makes the position of the flow-changing frame 8 move up in the vertical section in any vertical section in the filter barrel 2 as the flow-changing frame 8 rotates, thereby driving the impurities moved by the brush plate 7 to move upward relative to the ink, thereby reducing the impurity content in the ink near the filter frame 5, so that when the device processes the ink, especially when the amount of ink is reduced in the middle and late stages and the proportion of impurities in the range near the filter frame 5 in the ink increases, the influence of impurities on the speed of the ink passing through the filter frame 5 is reduced, thereby improving the speed of the device in removing impurities from the ink;

[0044] Moreover, the rotating flow-changing rack 8 can increase the force acting on the ink, so that the ink in the device is subjected to more force compared to the ink in a static state that is only subjected to gravity. Therefore, the ink in the device can more easily pass through the filter frame 5, thereby improving the filtering efficiency of the ink in the device from the perspective of the ink.

[0045] See also Figure 1 , Figure 2 , Figure 4 and Figure 5 , and also includes: a vibration component installed at the bottom of the filter barrel 2, the vibration component is connected to the filter frame 5 to control the vibration of the filter frame 5, wherein the vibration component includes: a fixed frame 10 fixedly installed at the lower part of the filter barrel 2, the filter frame 5 and the fixed frame 10 are slidably installed; a spring A11 fixedly installed between the filter frame 5 and the fixed frame 10, the spring A11 is used to restore the position of the filter frame 5 after the movement; a rotating frame 12 rotatably installed at the lower part of the filter barrel 2, the rotating frame 12 is fixed to the rotating shaft 6, the rotating frame 12 is located below the filter frame 5, the rotating shaft 6 passes through the filter frame 5 and is rotatably and slidably connected to the filter frame 5; a top ball 13 fixedly installed on the top surface of the rotating frame 12, the top ball 13 is annularly arranged on the rotating frame 12; a ball groove 14 is opened on the bottom surface of the filter frame 5, the ball groove 14 is annularly arranged on the filter frame 5, the position of the top ball 13 corresponds to the position of the ball groove 14, and each top ball 13 can be correspondingly sunken into each ball groove 14.

[0046] The motor 9 is started to control the rotating frame 12 to rotate relative to the filter frame 5. During the process, the top ball 13 moves relative to the filter frame 5. The top ball 13 first moves out of the ball groove 14, and squeezes the filter frame 5 to move upward, and the spring A11 is compressed. Then, when the top ball 13 moves to the position of the next adjacent ball groove 14, the spring A11 is restored, so that the filter frame 5 moves downward, and the top ball 13 is sunk into the ball groove 14 again. Therefore, the rotating rotating frame 12 can control the filter frame 5 to move up and down continuously through the cooperation of the ball groove 14 and the top ball 13, so as to achieve the effect of vibrating the filter frame 5;

[0047] The vibrating filter frame 5 can produce a relative position change with the ink, thereby accelerating the speed of the ink passing through the filter frame 5; the vibrating filter frame 5 can continuously change the position of the intercepted impurities, thereby avoiding accidental impurities getting stuck on the filter frame 5 and causing them to be unable to be processed by the brush plate 7; therefore, based on the above two points, the vibrating filter frame 5 can further improve the impurity removal efficiency of the device for ink.

[0048] See also Figure 1 , Figure 2 , Figure 6 , Figure 7 and 8 , further comprising: a frame 15 slidably mounted on the filter barrel 2, the frame 15 being inserted into the filter barrel 2; an adsorption net 16 fixedly mounted on the frame 15, the adsorption net 16 being used to adsorb impurities, the frame 15 and the adsorption net 16 thereon being provided with sixteen, the frame 15 being evenly annularly arranged on the inner ring side of the filter barrel 2; a card bead 17 slidably mounted on the frame 15, a card groove being provided on the side wall of the filter barrel 2, the card groove being fitted with the card bead 17; a spring B18 fixedly mounted between the card bead 17 and the frame 15, the spring B18 being used to card the card bead 17 into the card groove, The frame 15 is fixed on the filter barrel 2; the push plate 19 is fixedly installed on the rotating shaft 6, and the cross-section of the push plate 19 is set to be triangular. The position of the push plate 19 makes the base of the triangle close to the rotating shaft 6, and the position of the vertex of the triangle is far away from the rotating shaft 6. Therefore, when the push plate 19 is rotated by the rotating shaft 6, the shape of the push plate 19 will guide the ink to flow to its farthest end. The frame 15 is tilted, and the special angle position of the frame 15 makes it perpendicular to the flow direction of the ink guided to the position of the frame 15 by the push plate 19.

[0049] When the rotating shaft 6 rotates, the impurities are first controlled by the flow-changing frame 8 to move upward relative to the ink. At the same time, the flow-pushing plate 19 is rotated, so that the ink is guided by the flow-pushing plate 19 to flow to the frame 15. Therefore, the ink can drive the impurities that have been moved upward to move to the adsorption net 16. The ink passes through the adsorption net 16, and the impurities are adsorbed by the adsorption net 16. Therefore, in this device, it is possible to reduce the impurities from following the ink for a second or even more times of filtering, thereby reducing the impurities from gathering toward the filter frame 5, reducing the influence of the impurities on the speed of the ink passing through the filter frame 5, and further improving the impurity removal efficiency of the device for the ink.

[0050] When the adsorption net 16 adsorbs more impurities, the frame 15 is directly moved upward. During the process, the card beads 17 are pressurized and the spring B18 is compressed, so that the frame 15 can be released and the frame 15 and the adsorption net 16 can be freely taken out to deal with the impurities on the adsorption net 16, or replace the new adsorption net 16 to maintain the impurity adsorption capacity of the adsorption net 16; after completion, the frame 15 can be reinserted into the filter frame 5, and the card column is re-inserted into the card slot to fix the position of the frame 15.

[0051] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
