The length direction of brush hair 45 is the same with the length direction of outer filter 33, and the length of brush hair 45 is the same with the length of outer filter 33, and the brush hair 45 of being convenient for can better be cleaned and brushed outer filter 33, and interior filter 2222 is sieve network structure with outer filter 33, and the mesh number of interior filter 2222 is less than the mesh number of outer filter 33, is convenient for play different filtration screening effects to the material as required.
The working principle of the invention is as follows: according to the condition of the materials, the intermediate pipeline 21 and the filter box body 22 in the particle filtering treatment device 2 are independently used for filtering the materials (and the larger impurities mixed in the materials), or the intermediate pipeline 21, the filter box body 22 and the filtering anti-blocking device 5 are simultaneously used; when only the intermediate pipe 21 and the filter box 22 are used, because one end of the filter pipe 52 in the filtering anti-blocking device 5 is connected with the first flange 211 through the second flange 51, and further the filter pipe 52 is connected with the intermediate pipe 21, the filtering anti-blocking device 5 can be removed, at this time, the material enters the discharge pipe 11 and the intermediate pipe 21 from the pneumatic conveyor body 1 in sequence, the partition plate is arranged inside the intermediate pipe 21, because the upper frame 2221 is fixedly arranged on the bottom surface of the partition plate, when the material enters the intermediate pipe 21 (the end far away from the filtering anti-blocking device 5), the material can only enter one side of the upper cavity 222 due to the blocking of the partition plate, enters the other side of the upper cavity 222 through the filtration of the inner filter plate 2222, and then enters the intermediate pipe 21 (the end close to the filtering anti-blocking device 5) to be discharged finally, the materials (and the larger impurities mixed in the materials) are adhered to the inner filter plate 2222 or are blocked and stay in the upper cavity 222, the materials with uniform sizes are finally discharged from the middle pipeline 21 through the inner filter plate 2222, and the discharge doors arranged on the upper cavity 222 and the lower cavity 223 are convenient for cleaning the interiors of the upper cavity 222 (and the inner filter plate 2222) and the lower cavity 223;
when the outer filter plate 33 and the inner filter plate 2222 are required to filter and screen materials at the same time, the air cylinder 32 can be started to move the outer filter plate 33 towards the upper frame 2221, at this time, the outer filter plate 33 can be sleeved outside the inner filter plate 2222 (the outer filter plate 33 and the inner filter plate 2222 are both positioned in the upper cavity 222), and at this time, the materials can be sequentially filtered and screened through the outer filter plate 33 and the inner filter plate 2222; because the two ends of the top surface of the lower frame 34 are provided with the buffer springs 341, when the air cylinder 32 moves the outer filter plate 33 toward the upper frame 2221, the outer filter plate 33 can be buffered; when the outer filter plate 33 is not used, the outer filter plate 33 is driven by the cylinder 32 to be positioned in the lower cavity 223, at the moment, the outer filter plate 33 is sleeved outside the outer filter plate cleaning device 4, the starting motor 41 drives the bristle solid rod 42 to rotate, the arc-shaped brush rod 43 rotates in the direction away from the bristle solid rod 42 by taking the rotating shaft 431 with the torsion spring as the shaft under the action of centrifugal force generated by the rotation of the bristle solid rod 42, at the moment, the bristles 45 arranged on the arc-shaped outer wall of the arc-shaped brush rod 43 can clean materials (and large impurities mixed in the materials) adhered on the outer filter plate 33, the materials (and the large impurities mixed in the materials) adhered on the outer filter plate 33 can fall into the lower cavity 223, after the cleaning is finished, the motor 41 is stopped, and under the action of the rotating shaft 431 with the torsion spring, the arc-shaped brush rod 43 rotates in the direction close to the bristle solid rod 42 by taking the rotating shaft 431 with the torsion spring as the shaft, And is abutted against the fixed leaning rod 44, so that when the outer filter plate cleaning device 4 is not used and the outer filter plate 33 moves outside the outer filter plate cleaning device 4, no interference is generated between the two;
when the intermediate pipeline 21, the filter box 22 and the filtering and anti-blocking device 5 are used simultaneously, one end of the filter pipe 52 in the filtering and anti-blocking device 5 is connected with the first flange plate 211 through the second flange plate 51, so that the filter pipe 52 is connected with the intermediate pipeline 21, the material filtered by the intermediate pipeline 21 (close to one end of the filtering and anti-blocking device 5) can enter the filter pipe 52 after being filtered again through the filter screen 523 (at this time, the overturning motor 534 should be started first, so that the cover body 533 is driven to overturn towards the opening at the other end of the filter pipe 52 through the overturning shaft 532, the opening at the other end of the filter pipe 52 can be blocked and sealed, and the discharging effect cannot be influenced); when the filtering anti-blocking device 5 is not used, the cover 533 can be opened, so that the interior of the filtering pipe 52 can be cleaned conveniently; or when the material in the tank body 541 is full (or when the tank body 541 and the filtering pipe 52 are blocked), the cover body 533 can be opened, so that the material is discharged from the opening at the other end of the filtering pipe 52; also be provided with the brush body on the inner wall of outer filter 33 for after starting cylinder 32 and moving outer filter 33 to framework 2221 direction, when outer filter 33 cover was established in the outside of inner filter 2222, the brush body can be cleaned with water to the material of adhesion (and the great debris that mix with in the material) on inner filter 2222, and the material after the cleaning with water (and the great debris that mix with in the material) can fall to in the cavity 222.
Although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that changes may be made in the embodiments and/or equivalents thereof without departing from the spirit and scope of the invention. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
