[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] See also Figure 1-4 , the utility model provides a technical solution:

[0027] A powder filtering device, comprising:

[0028] Main structure and filtering mechanism;

[0029] The main structure includes a filter bin 1, a feed bin 2 and a discharge bin 3. The feed bin 2 is hinged at the upper end of the filter bin 1, and the discharge bin 3 is integrally formed and arranged at the lower end of the filter bin 1. A feed port is arranged at the upper end of the feed bin 2, and a discharge port is arranged at the lower end of the discharge bin 3. A feed hopper 11 connected to the feed port is arranged inside the feed bin 2. The feed hopper 11 is funnel-shaped with a larger upper part and a smaller lower part, and the lower end of the feed hopper 11 is directly opposite to the opening of the filter box 4.

[0030] In actual use, the material is loaded through the feed port at the upper end of the feed bin 2, the powder enters the filter box 4 through the feed hopper 11, and the filtered powder is collected through the discharge port of the discharge bin 3. Large particles and impurities remain in the filter box 4 and can be cleaned after a period of time.

[0031] Among them, a surrounding edge is arranged around the outer wall of the lower end of the filter bin 1, and legs are welded at the bottom of the surrounding edge, and the legs are symmetrically arranged in an eight-shaped shape. When collecting powder, the corresponding container can be placed directly below the discharge port.

[0032] See also Figure 2-3 :

[0033] The filter mechanism includes a filter box 4 that can move horizontally in the filter bin 1 and a filter plate 5 arranged at the bottom of the filter box 4. Slide rods 6 are symmetrically arranged on both side walls of the filter box 4. Slide grooves 7 are opened on both side walls of the filter bin 1. The slide rods 6 are slidably arranged in the slide grooves 7.

[0034] It also includes a driving mechanism for driving the filter box 4 to move. The driving mechanism includes a motor 8, a driving arm 9 and a driven arm 10 installed on a side wall of the filter bin 1. The output end of the motor 8 is fixedly connected to a rotating shaft, and the driving arm 9 is arranged on the rotating shaft. The end of the driving arm 9 is rotatably connected to one end of the driven arm 10, and the other end of the driven arm 10 is rotatably connected to the end of one group of slide bars 6. The length of the driving arm 9 is half the length of the slide slot 7.

[0035] In actual use, the starting motor 8 drives the active arm 9 to rotate. Since the end of the active arm 9 is hinged to one end of the driven arm 10, and the other end of the driven arm 10 is hinged to the end of the slide rod 6, the active arm 9 can pull the slide rod 6 to reciprocate in the slide groove 7 when it rotates, so that the powder entering the filter box 4 can be screened and filtered during the reciprocating motion, which has good filtering effect and efficiency.

[0036] Also, see Figure 3 In order to increase the stability of the equipment, this application also makes the following designs:

[0037] Guide rods 12 are symmetrically arranged on the two outer side walls of the filter box 4, and the guide rods 12 are slidably inserted into the outer wall of the filter bin 1. Two sets of washers 14 are sleeved on the guide rods 12 between the inner wall of the filter bin 1 and the outer wall of the filter box 4, and a compression spring 15 is sleeved between the two sets of washers 14 on the guide rods 12. The ends of the guide rods 12 extend to the outside of the filter bin 1, and the ends of the guide rods 12 are connected to the limit blocks 13.

[0038] When the filter box 4 reciprocates, the guide rod 12 can play a good guiding role, so that the filter box 4 always moves in the same straight line. At the same time, the compression spring 15 and the rubber gasket 14 on the guide rod 12 can play a certain buffering role, thereby improving the stability of the equipment.

[0039] The length of the guide rod 12 located outside the filter bin 1 is greater than half the length of the chute 7 , which can facilitate the reciprocating motion of the filter box 4 .

[0040] See also Figure 4 In order to regularly clean the impurities and large particles in the filter box 4, the present application makes the following design:

[0041] One side wall at the lower end of the feed bin 2 is hinged to one side wall at the upper end of the filter bin 1 through a hinge, and the other side wall at the lower end of the feed bin 2 and the other side wall at the upper end of the filter bin 1 are both provided with ear seats 16 for installing fixing screws.

[0042] When the filter box 4 needs to be cleaned after the equipment has been used for a period of time, the fixing screws on the ear seat 16 are removed, and the feed bin 2 is flipped open to expose the filter box 4 and the interior of the filter bin 1. The staff can now clean the filter box 4 and the interior of the filter bin 1, which is convenient for the subsequent use of the equipment and for maintenance and cleaning of the interior of the equipment.

[0043] Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are exemplary and cannot be understood as limitations of the present invention. Ordinary technicians in this field can change, modify, replace and modify the above embodiments within the scope of the present invention.
