[0034] The crushing assembly 700 is also included. The crushing assembly 700 is arranged inside the crushing box 100. The crushing assembly 700 includes a plurality of fixed crushing plates 710 arranged in a fixed array on the inner peripheral side of the crushing box 100 and a plurality of movable crushing plates 720 arranged in a movable array inside the crushing box 100. The movable crushing plates 720 and the fixed crushing plates 710 are movable and staggered. A driving assembly 730 is fixed on the movable crushing plates 720.

[0035] Each group of movable crushing plates 720 includes a plurality of crushing bars 721 arranged horizontally and longitudinally, and positions corresponding to the crushing bars 721 on the fixed crushing plates 710 are provided with extrusion grooves 722, and the crushing bars 721 move through the extrusion grooves 722; by setting the extrusion grooves 722, the crushing bars 721 can crush and extrude the molecular sieve when passing through the extrusion grooves 722 on the fixed crushing plates 710.

[0036] A plurality of collision wedges 711 are fixed on the fixed crushing plate 710 and the movable crushing plate 720. By arranging the collision wedges 711, during the rotation of the movable crushing plate 720, the molecular sieve can be strongly collided and crushed.

[0037] Specifically, the arc-shaped square tube 300 is a half circular square tube. Through the above structural design, the molecular sieves staying in the arc-shaped square tube 300 can slide down from the inner wall of the arc-shaped square tube 300, which is convenient for cleaning the molecular sieves.

[0038] Specifically, the driving assembly 730 includes a rotating shaft 731 movably disposed inside the crushing box 100, and a driving unit 732 is fixed to one end of the rotating shaft 731. The driving unit 732 is a motor, which is fixed to the back of the crushing box 100, and the output shaft of the motor is fixedly connected to one end of the rotating shaft 731.

[0039] Specifically, a plurality of pulverizing bars 721 at the same horizontal longitudinal position are fixedly connected to a connecting plate, and the connecting plate is fixedly connected to the driving assembly 730 .

[0040] Specifically, the bottom end of the crushing box 100 is provided with an opening 110 corresponding to the position of the feed opening 400, and a filter screen 120 is fixed on the opening 110. The filter screen 120 is used to screen the crushed molecular sieve, and the molecular sieve that meets the mesh number falls through the filter screen 120, and the molecular sieve that does not meet the mesh number is circulated and crushed multiple times inside the crushing box 100.

[0041] Specifically, fixed plates are symmetrically fixed on both sides of the corresponding opening 110 between the arc-shaped square tube 300 and the crushing box 100, and the adjustment assembly 600 includes a fixed block fixedly connected to one side of the filter plate 500, and a shaft 610 is rotatably sleeved on the fixed block. Slots are formed on opposite sides of the fixed plate, and the shaft 610 is fixed inside the slots, and the fixed block is movably connected inside the slots.

[0042] The fixing block is provided with an axial hole 620, and the shaft rod 610 is sleeved in the axial hole 620. The shaft rod 610 is slidably connected in the axial hole 620, and a torsion spring 630 is provided between the inner wall of the axial hole 620 and the outer wall of the shaft rod 610. Under normal circumstances, the filter screen plate 500 and the inner wall of the feed opening 400 are in contact with each other, and the filter screen plate 500 blocks the molecular sieve again, allowing only dust to pass through; when there is a lot of dust on the filter screen plate 500 to form a blockage, the filter screen plate 500 is held by hand and moved inwardly, and the filter screen plate 500 can be automatically reset under the drive of the torsion spring 630, so that the dust adhering to the filter screen plate 500 can be easily removed, and the operation is convenient.

[0043] Specifically, the driving assembly 730 is disposed on the inner side of the fixed crushing plate 710 .

[0044] Specifically, a feeding funnel is fixed on the top of the crushing box 100. Molecular sieves are added into the crushing box 100 through the feeding funnel.

[0045] Specifically, the adsorption assembly 200 includes an adsorption box, the bottom end of which is connected to the arc-shaped square tube 300 on the same side, and the upper end of the adsorption box is fixedly connected to a connecting pipe, and the other end of the connecting pipe is connected to the inside of the crushing box 100;

[0046] The adsorption box has a dust filter plate inside and an exhaust fan inside. By starting the exhaust fan, the dust passing through the discharge port 400 is adsorbed into the arc-shaped square tube 300 after passing through the filter screen plate 500, the dust filter plate filters the dust, and the filter screen plate 500 blocks the molecular sieve to prevent the molecular sieve from entering the arc-shaped square tube 300 driven by the exhaust fan.

[0047] When the molecular sieve crushing device of the embodiment of the present application is actually used: the molecular sieve is added into the crushing box 100 from the feeding funnel, the motor and the exhaust fan of the driving part 732 are started, the output shaft of the motor drives the rotating shaft 731 to rotate, the rotating shaft 731 drives the crushing bar 721 to flip, the crushing bar 721 drives the molecular sieve to move, and collides with the crushing bar 721 and the collision wedge 711 on the fixed crushing plate 710 to crush, and at the same time, when the crushing bar 721 passes through the extrusion groove 722 on the fixed crushing plate 710, the molecular sieve between the crushing bar 721 and the extrusion groove 722 can be squeezed to enhance the crushing effect;

[0048] The molecular sieve that meets the mesh number requirement after crushing falls through the filter screen 120 and falls through the discharge port 400 at the bottom of the two arc-shaped square tubes 300. Under the action of the exhaust fan, the dust passes through the filter screen plate 500 and enters the adsorption box after passing through the arc-shaped square tube 300. Among them, the filter screen plate 500 blocks the large particles of molecular sieve to prevent the molecular sieve from entering the arc-shaped square tube 300 and causing blockage.

[0049] When the filter plate 500 needs to be cleaned, the lower end of the filter plate 500 is held and flipped inward, and the filter plate 500 leaves the arc-shaped square tube 300. Then the filter plate 500 is released, and driven by the torsion spring 630, the filter plate 500 is flipped back and forth multiple times, which can easily remove the dust adhering to the filter plate 500.

[0050] The above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. For those skilled in the art, the utility model may have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
