A fan 6 is installed on the top of the dust collection box 1. The fan 6 consists of a drive motor and a fan. The drive motor drives the fan to rotate, generating negative pressure, thereby drawing kiln dust and flue gas into the interior of the dust collection box 1. Since this dust collection method is existing technology in the field and not unique, it will not be described in detail. A filter mechanism is installed inside the dust collection box 1 to filter dust.
[0049] It should be noted that the bottom of the dust collection box 1 is equipped with a discharge pipe and a dust collection bucket. The filtered dust, waste and other debris are sent into the dust collection bucket at the bottom of the dust collection box 1 through the discharge pipe. The dust collection bucket can be replaced or cleaned as needed. The discharge pipe and the dust collection bucket are existing technologies in this field, so they will not be described in detail.
[0050] Furthermore, the filtration mechanism includes a fixing block 7, a spring 8, a connecting plate 9, a mounting frame 10, and a filter screen 11.

[0054] Further, the mounting frame 10, the filter screen 11, etc. are provided with two about the cam 94 axis symmetry.
[0055] It should be noted that the mounting frame 10, the filter screen 11, the spring 8, etc. are provided with two, the filter screen 11 is provided with two up and down, the filter hole diameters of the upper and lower filter screens 11 are not the same, and the interval between the upper and lower filter screens 11 and the cam 94 is consistent with the rotation interval, when the cam 94 rotates, it will contact the upper and lower filter screens 11 in turn, so that multi-stage filtering is performed, and dust filtering is more uniform.
[0056] The utility model can be described by the following operation mode to explain its function principle:
[0057] When using, the dust collecting box 1 is placed against the kiln opening, when dust is discharged from the kiln opening, the fan 6 is started, the dust cover 5 is made to suck dust into the air pipe 3 and into the feeding pipe 2 and fall on the upper filter screen 11 by the suction force of the fan 6, and the motor 92 is started to drive the transmission rod 93 to rotate the cam 94, when the cam 94 rotates, it will first contact the upper filter screen 11, the upper filter screen 11 shakes and extrudes the upper spring 8 under the force, with the rotation of the cam 94, when the cam 94 rotates to contact the lower filter screen 11, the lower spring 8 is extruded, at this moment, the upper spring 8 releases the extrusion force and drives it to reset, so that the upper filter screen 11 shakes and resets, with the continuous rotation of the cam 94, the upper filter screen 11 and the lower filter screen 11 intermittently shake, so that the filter screen 11 performs multi-layer filtering on dust, and the dust in the flue gas generated when the kiln opening burns is completely filtered.
[0058] When the filter screen 11 is replaced after being blocked for a long time, the nut 1003 is rotated, the nut 1003 slides along the screw diameter of the screw groove 1002 under the force until the nut 1003 is separated from the mounting rod 1001, then the clamping block 1101 is pulled upward, the clamping block 1101 drives the filter screen to slide and separate from the mounting frame 10, so that the filter screen 11 is quickly disassembled and cleaned, avoiding the influence of the filter screen 11 blockage on its filtering performance.
[0059] The above is only a preferred specific embodiment of the utility model, but the protection scope of the utility model is not limited to this, any skilled person in the art can make equivalent replacement or change according to the technical scheme and the utility model concept of the utility model within the technical range disclosed by the utility model, which should be covered in the protection scope of the utility model.
