[0022] 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.
[0023] like Figures 1 to 5 As shown, this embodiment discloses an adhesive raw material filtration device, including a housing 1. The housing 1 includes a mounting cavity 11, a feed inlet 12 located at the upper part of the mounting cavity 11, and a first discharge port 13 located at the lower part of the mounting cavity 11. A filter cylinder 2 is fixedly connected inside the mounting cavity 11. The filter cylinder 2 has a feed hole 21 on its side facing the feed inlet 12. One side of the mounting cavity 11 is open and a cover plate 3 is closed at the opening. The mounting cavity 11 is arranged horizontally. The cover plate 3 is fixedly connected to the housing 1 by bolts. A driver 4 is fixed outside the cover plate 3. The driver 4 is a motor. A stirring paddle 5 is provided inside the filter cylinder 2. The stirring paddle 5 is connected to the drive shaft of the driver 4. The cross-sectional dimension of the mounting cavity 11 is larger than the dimension of the filter cylinder 2. A sleeve 8 is inserted into the feed inlet 12. The lower end of the sleeve 8 passes through the feed hole 21 and is inserted into the filter cylinder 2. By setting the sleeve 8, it can be ensured that the borax raw material entering from the feed inlet 12 can smoothly enter the interior of the filter cylinder 2.
[0024] The filter cartridge 2 has a dense mesh around its periphery. In use, borax is fed into the filter cartridge 2 through the feed port 12 via a powder pump (existing technology, not shown in the figure). The driver 4 drives the stirring paddle 5 to stir, thereby agitating the borax inside the filter cartridge 2. Fine borax can pass through the mesh around the filter cartridge 2 and enter the mounting cavity 11, and fall from the first discharge port 13, thus achieving the filtration of borax. By setting the driver 4 and the stirring paddle 5, the filtration effect of borax can be effectively improved.
[0025] like Figure 2 and Figure 5As shown, the mounting cavity 11 has a limiting groove 14 at one end away from its opening, and the inner wall of the limiting groove 14 has a protruding rib 15, with one protruding rib 15. The filter cartridge 2 has an annular rib 23 on the side away from its opening, and the annular rib 23 has a notch 24. The annular rib 23 is inserted into the limiting groove 14 and the protruding rib 15 is inserted into the notch 24 for limiting. Through the above design, the installation limiting and installation positioning of the filter cartridge 2 can be realized, thereby improving the installation accuracy and installation reliability of the filter cartridge 2.
[0026] like Figure 2 and Figure 3 As shown, the housing 1 and the filter cartridge 2 are fixed by a bushing 9. The filter cartridge 2 has an annular platform 25 on its open side. The bushing 9 is inserted into the mounting cavity 11 and is sleeved on the outside of the filter cartridge 2. The bushing 9 includes a first annular surface 91 and a second annular surface 92. The inner side of the first annular surface 91 abuts against the outer side of the opening of the mounting cavity 11. The inner side of the cover plate 3 abuts against the outer side of the first annular surface 91. The outer side of the second annular surface 92 abuts against the inner side of the annular platform 25. Through the cooperation of the filter cartridge 2, the cover plate 3 and the bushing 9, the filter cartridge 2 can be fixedly installed, which is beneficial to improving the installation effect of the filter cartridge 2.
[0027] The cover plate 3 has a boss 31 on its inner side. By setting the boss 31, the boss 31 is inserted into the filter cylinder 2 and blocks the opening on one side of the filter cylinder 2, thereby preventing borax from leaking from the opening of the filter cylinder 2. The installation method of the filter cylinder 2 in this embodiment is as follows: S1, insert the bushing 9 into the installation cavity 11; S2, insert the filter cylinder 2 horizontally into the installation cavity 11, the filter cylinder 2 passes through the bushing 9, the annular rib 23 of the filter cylinder 2 is inserted into the limiting groove 14 and the protruding rib 15 is inserted into the notch 24, thereby realizing the positioning installation of the filter cylinder 2; S3, then fix the cover plate 3 and the shell 1 with bolts, the cover plate 3 covers the installation cavity 11, the boss 31 is inserted into the filter cylinder 2, and the stirring paddle 5 is inserted into the filter cylinder 2; S4, then insert the sleeve 8 into the feed port 12, so that the lower end of the sleeve 8 is inserted into the filter cylinder 2 from the feed hole 21, completing the installation of the filter cylinder 2;
[0028] As can be seen from the above, the filter cartridge 2 is a detachable design. When the filtration effect of the filter cartridge 2 decreases, the filter cartridge 2 can be removed from the mounting cavity 11 for cleaning or replacement.
[0029] like Figure 2As shown, the housing 1 has a second discharge port 16 on its side, and the filter cartridge 2 has a discharge port 22 at its lower part away from the feed hole 21. The discharge port 22 and the second discharge port 16 are connected or blocked by a sealing head 61. Specifically, the housing 1 has an installation groove 18 inside, which is located directly below the discharge port 22. A lifting device 6 is installed in the installation groove 18. The lifting device 6 is existing technology. The end of the lifting device 6 is connected to the sealing head 61. The lifting device 6 can drive the sealing head 61 to move up and down, so that the sealing head 61 can be inserted into or removed from the discharge port 22. The second discharge port 16 is located inside the housing 1. The housing 1 is inclined downwards to the outside. The housing 1 has a discharge channel 17 inside, which is located directly below the discharge hole 22. The upper part of the discharge channel 17 abuts against the side wall of the filter cartridge 2. The sealing head 61 is located inside the discharge channel 17. The second discharge port 16 is connected to the discharge channel 17. The lower end of the discharge channel 17 is lower than the connection between the second discharge port 16 and the discharge channel 17. The lower part of the sealing head 61 can abut against the lower end of the discharge channel 17 so that the second discharge port 16, the discharge channel 17 and the discharge hole 22 are connected. The outer side of the housing 1 is connected to a receiving groove 7, which is located below the second discharge port 16.
[0030] When the filter cartridge 2 is performing normal filtration, the sealing head 61 blocks the discharge hole 22. After the borax filtration is completed, large particles of borax will remain inside the filter cartridge 2. At this time, the lifting device 6 drives the sealing head 61 to descend, so that the second discharge port 16, the discharge channel 17 and the discharge hole 22 are connected. Then, the driving device 4 drives the stirring paddle 5 to rotate, and the large particles of borax will move inside the filter cartridge 2. When the borax moves to the discharge hole 22, the large particles of borax can be discharged from the discharge hole 22 and fall into the receiving trough 7 after passing through the discharge channel 17 and the second discharge port 16, thus realizing the discharge of large particles of borax impurities.
[0031] like Figure 1 As shown, the lower part of the housing 1 is provided with a base 19. The base 19 is inclined upward from the opening of the mounting cavity 11 toward the opposite side. The angle between the base 19 and the horizontal plane is 2°-5°, preferably 2°. By setting the inclined base 19, when the housing 1 is installed on the top of the glue preparation chamber, the housing 1 will be in a state of left low and right high, that is, the side of the driver 4 is high. At this time, it is equivalent to the filter cartridge 2 being inclined, and the discharge hole 22 is located at the lowest point of the inclined end, which is conducive to the discharge of large particles of borax.
[0032] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
