DETAILED DESCRIPTION

[0032] 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 of 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. Specific embodiment 1

[0034] See also Figures 1 to 5 The utility model is a dust suppression structure of an air flow pulverizer, comprising an air flow pulverizer body 1 and a dust reduction bin 101 arranged on one side above the air flow pulverizer body, a dust removal bin 103 is installed at the bottom of the dust reduction bin 101, a screening component 2 is arranged at the lower part of the interior of the dust reduction bin 101, and a vibration component 3 is arranged on one side of the front end face of the dust reduction bin 101; the screening component 2 comprises a screen 201 and tension springs 202 evenly spaced from front to back and installed on one side of the bottom thereof, and the other side of the bottom of the screen 201 is movably connected to the inner wall of the dust reduction bin 101 through a hinge; the vibration component 3 comprises a rotating motor 301 and an eccentric wheel 302 installed on its output shaft.

[0035] Specifically, a connecting pipe 1011 is arranged above the outer wall of one side of the dust reduction bin 101, and the other end of the connecting pipe 1011 is connected to the discharge pipe on the air flow pulverizer body 1 through a flange, and a discharge pipe 1012 is arranged at the center position of the outer wall of the other side of the dust reduction bin 101, and a ventilation mechanism 102 is arranged at the top center position of the dust reduction bin 101, and an inspection door 1031 is installed below the rear end face of the dust removal bin 103, and an exhaust pipe 1032 is arranged at the bottom front end of the dust removal bin 103, and the bottom end of the tension spring 202 is fixed to the upper surface of the fixed plate 203, and one side end face of the fixed plate 203 is fixed to the inner wall of the dust reduction bin 101.

[0036] Furthermore, one end of the screen 201 can rotate under the action of the hinge, and the tension spring 202 can apply force to the bottom of the other end of the screen 201. The operation of the rotating motor 301 can drive the eccentric wheel 302 to rotate and apply a reciprocating force to the screen 201. The air flow mill body 1 and the ventilation mechanism 102 are both existing technologies, so they will not be described in detail here.

[0037] The operation process of this embodiment is as follows: the air flow mill body 1 crushes the material to be crushed, and the crushed material is discharged into the dust suppression bin 101 through the discharge pipe and the connecting pipe 1011. At this time, the ventilation mechanism 102 is started, and the crushed material is blown to the surface of the screen 201 by the ventilation mechanism 102. The material can be filtered on the surface of the screen 201, and the dust contained therein is blown to the bottom of the screen 201. At this time, the rotating motor 301 is started, and the output shaft of the rotating motor 301 rotates to drive the eccentric wheel 302 to rotate. Since the eccentric wheel 302 is located on the screen 201, the eccentric wheel 302 is rotated. 01, therefore, when the eccentric wheel 302 rotates, it will continuously push one end of the screen 201 to move upward, wherein the other end of the screen 201 is installed on the inner wall of the dust reduction bin 101 through a hinge, so one end of the screen 201 moves upward and stretches the tension spring 202, and at the same time, with the elastic performance of the tension spring 202, one end of the screen 201 will continuously vibrate, so that the crushed material on the surface of the screen 201 can be shaken off and then discharged from the discharge pipe 1012, so as to avoid more material accumulation on the surface of the screen 201, which affects the dust filtering efficiency and effect. Specific embodiment 2

[0039] See also Figure 3 , 6 On the basis of the specific embodiment 1, what is different from the first embodiment is that: an adjustment component 4 is provided, the adjustment component 4 includes an adjustment motor 401 and a rotating shaft 4011 installed on its output shaft through a coupling, the other end of the rotating shaft 4011 passes through the bearing on the outer wall of one side of the dust removal bin 103 and is connected to the active roller 402, which solves the existing problem that when disassembling and replacing the impurity collection bin, the entire equipment needs to be shut down for a long time, which is time-consuming and labor-intensive, and dust cannot be continuously processed, resulting in low work efficiency.

[0040] Specifically, a chain plate 403 is sleeved on the outer side of the outer wall of the active roller 402, and an auxiliary roller 404 is installed on the other side of the chain plate 403. The outer wall of the auxiliary roller 404 is movably connected to the inner wall of the dust removal bin 103. Left mounting plates 405 are installed on the upper and lower front and rear sides of the inner wall of the chain plate 403. A right mounting plate 406 is oppositely arranged on the right side of the left mounting plate 405. An impurity collecting bin 408 is inserted between the opposite end faces of the left mounting plate 405 and the right mounting plate 406. The outer wall of the right mounting plate 406 is installed on the inner wall of the limiting track 407, and the outer wall of the limiting track 407 is installed on the inner wall of one side of the dust removal bin 103.

[0041] Furthermore, the operation of the adjusting motor 401 can drive the rotating shaft 4011 to rotate, and drive the active roller 402 to rotate through the rotating shaft 4011, and at the same time drive the chain plate 403 to move with the assistance of the auxiliary roller 404, and at the same time make the left mounting plate 405 move, and drive the impurity collecting bin 408 to move under the action of the right mounting plate 406 and the limiting track 407, wherein the impurity collecting bin 408 is provided with two groups, and the two impurity collecting bins 408 are interchanged by the movement of the chain plate 403.

[0042] The operation process of this embodiment is as follows: after the dust in the material is blown and filtered to the bottom of the screen 201 under the action of the ventilation mechanism 102, the dust will fall into the impurity collection bin 408 located at the bottom of the dust reduction bin 101, and after the dust collection inside a group of impurity collection bins 408 is completed, the adjustment motor 401 is started, and the output shaft of the adjustment motor 401 rotates to drive the rotating shaft 4011 to rotate under the action of the coupling, and the rotation of the rotating shaft 4011 will drive the active roller 402 at the inner end to rotate, and the active roller 402 and the auxiliary roller 404 are driven by the rotation of the two. The chain plate 403 on the outer wall moves, and the movement of the chain plate 403 will drive the left mounting plate 405 to move, and with the assistance of the right mounting plate 406 and the limiting track 407, the impurity collecting bin 408 follows the movement, and the positions of the two groups of impurity collecting bins 408 can be adjusted. The impurity collecting bin 408 filled with dust can be taken out, cleaned and replaced through the inspection door 1031, and then the positions of the two groups of impurity collecting bins 408 can be quickly adjusted, which greatly shortens the time for replacing the impurity collecting bin 408, achieves the purpose of continuous dust treatment, and has high work efficiency.
