[0045] Please refer to Figure 1 This embodiment provides a pulverizing device 1000, which includes: a feeding mechanism 100, a pulverizing mechanism 200, a post-processing mechanism 400, a water mist mechanism 300 and a controller (not shown in the figure).

[0046] The feed mechanism 100 is used to feed raw materials into the crushing mechanism 200. The outlet of the crushing mechanism 200 is connected to the inlet of the post-processing mechanism 400. The water mist outlet of the water mist mechanism 300 is connected to the post-processing mechanism 400. Both the feed mechanism 100 and the water mist mechanism 300 are electrically connected to the controller.

[0047] Please combine Figures 2 to 8 The post-processing mechanism 400 includes: a processing tank 410, a control shaft 420, a driving rod group 430, an agitator 440 and a dust extraction component.

[0048] The inner cavity of the processing tank 410 is cylindrical, and the axis of the inner cavity of the processing tank 410 is horizontally arranged.

[0049] The control shaft 420 is disposed axially along the inner cavity of the processing tank 410. The control shaft 420 penetrates the end wall of the processing tank 410 and extends into the inner cavity of the processing tank 410. A portion of the control shaft 420 is located outside the processing tank 410, and the portion of the control shaft 420 located outside the processing tank 410 is driven by a driver (not shown).

[0050] The control shaft 420 is eccentrically disposed relative to the inner cavity of the processing tank 410, with the axis lines of the control shaft 420 and the inner cavity of the processing tank 410 being disposed horizontally. The control shaft 420 is rotatably engaged with the processing tank 410, and a rotational seal is formed between the control shaft 420 and the processing tank 410.

[0051] The driving rod assembly 430 includes a first driving rod 431 and a second driving rod 432 .

[0052] The first drive rod 431 and the second drive rod 432 are both radially disposed along the control shaft 420 and extend through the control shaft 420. Both the first drive rod 431 and the second drive rod 432 are slidably engaged with the control shaft 420 along their respective axial directions. The lengths of the first drive rod 431 and the second drive rod 432 are both greater than the maximum distance between the axis of the control shaft 420 and the inner annular wall of the inner cavity of the processing tank 410. The first drive rod 431 and the second drive rod 432 are spaced apart axially along the control shaft 420, and the angle between their projections on the cross-section of the control shaft 420 is acute.

[0053] The agitator 440 extends axially within the inner cavity of the processing tank 410 and is in contact with the inner circumferential wall of the inner cavity of the processing tank 410. The agitator 440 is slidably engaged with the processing tank 410 along the circumferential direction of the inner cavity of the processing tank 410. The agitator 440 is fixedly engaged with the processing tank 410 along the radial direction of the inner cavity of the processing tank 410. The agitator 440 is fixedly engaged with the processing tank 410 along the axial direction of the inner cavity of the processing tank 410.

[0054] The first driving rod 431 and the second driving rod 432 are both hingedly connected to the agitator 440 at the same end. The hinge axes of the first driving rod 431 and the second driving rod 432 and the agitator 440 are arranged along the axial direction of the inner cavity of the processing tank 410.

[0055] The dust extraction assembly includes an extraction tube 450 , a piston 460 and a plug rod 470 .

[0056] One end of the extraction tube 450 is fixedly connected to the side of the agitator 440 corresponding to the first drive rod 431, near the second drive rod 432. The extraction tube 450 extends along the circumference of the processing tank 410 toward the side where the second drive rod 432 is located. The piston 460 is slidably fitted within the extraction tube 450. The plug rod 470 is fixedly connected to the side of the piston 460 near the second drive rod 432. The plug rod 470 also extends along the circumference of the processing tank 410. The end of the plug rod 470 away from the piston 460 is fixedly connected to the side of the agitator 440 corresponding to the second drive rod 432, near the first drive rod 431.

[0057] A notch is formed in the sidewall of the extraction tube 450 near the first drive rod 431. This notch is sealed by a mesh plate 451. The mesh openings of the mesh plate 451 allow material dust to pass through while blocking the crushed material particles. It is understood that the aperture of the mesh plate 451 can be flexibly adjusted to suit the specific conditions for crushing different materials.

[0058] In this embodiment, the gap is further provided with a control plate 452, which is located below the mesh plate 451, which covers the control plate 452. The control plate 452 is provided with a dust inlet hole 453, and a dust inlet valve 454 is provided at the inner end of the dust inlet hole 453. In the natural state, the dust inlet valve 454 is in a normally closed state. The piston 460 is provided with a dust outlet hole 461, which passes through the piston 460, and a dust outlet valve 462 is provided at the outer end of the dust outlet hole 461. In the natural state, the dust outlet valve 462 is in a normally closed state.

[0059] During the pulverization process, the raw material to be pulverized is fed by the feeding mechanism 100 to the pulverizing mechanism 200. After being fully pulverized by the pulverizing mechanism 200, the pulverized material (including material dust) is conveyed through a pipeline to the processing tank 410 of the post-processing mechanism 400. Optionally, in order to effectively ensure the control effect of material dust, the amount of material in the processing tank 410 can be controlled not to exceed the control shaft 420.

[0060] After the crushed material (including material dust) enters the processing tank 410 of the post-processing mechanism 400, the driver drives the control shaft 420 to rotate, and the water mist mechanism 300 is used to send water mist into the processing tank 410. Through the stirring action of the driving rod group 430, the stirring member 440, and the dust extraction component, the dust in the material can be promoted to absorb water, thereby achieving the purpose of "settling" the dust. In this way, by wetting the crushed material (including material dust) to a certain extent with water mist, dust escape can be avoided. This is very useful for dry materials that need to be crushed before wet processing. It can effectively suppress the impact of dust generated by crushing on the surrounding environment and avoid material loss caused by dust escape.

[0061] The controller can determine the amount of material to be crushed by the pulverizing mechanism 200 in a single pass based on the feed rate of the feeding mechanism 100, and further determine the amount of pulverized material (including material dust) entering the processing tank 410 of the post-processing mechanism 400. Combined with the original moisture content of the material, the amount of water required to achieve the desired dust settling effect can be used to determine the amount of water to be added, i.e., the amount of water added. It should be noted that the amount of water added should be as small as possible, as long as it can achieve dust settling. This also prevents the powder from being over-moistened and adhering to the equipment.

[0062] After determining the amount of water to be added, the controller can add the atomized water to the treatment tank 410 of the post-processing mechanism 400 through the water mist mechanism 300 according to the preset water addition speed. When the water mist is introduced into the treatment tank 410 according to the preset water addition speed, the drive control shaft 420 is operated.

[0063] During the operation of the control shaft 420, the control shaft 420 drives the drive rod assembly 430 to move, and the drive rod assembly 430 smoothly drives the agitator 440 to move along the circumference of the inner cavity of the processing tank 410. In this way, the agitator 440 and the drive rod assembly 430 can be used to stir the powder system in the processing tank 410, thereby facilitating the complete removal of dust from the powder system, promoting the dust in the powder system to contact with the water mist and absorb moisture, and effectively improving the completeness of dust settling.

[0064] During the tumbling process, because the drive rod assembly 430 accelerates the agitator 440, only a relatively low rotational speed is required for the control shaft 420 to achieve a high linear velocity for the agitator 440 to move within the inner cavity of the processing tank 410. This saves energy while also ensuring a good tumbling effect. During the tumbling process, the drive rod assembly 430 slides along its own axis relative to the control shaft 420 based on the real-time position changes of the agitator 440, thereby adapting to the position changes of the agitator 440.

[0065] During the rotation of the control shaft 420, for the same drive rod group 430, the distance between the two stirring members 440 corresponding to the first drive rod 431 and the second drive rod 432 is in a changing state, periodically approaching and then moving away, thereby realizing the reciprocating motion of the piston 460 in the extraction tube 450.

[0066] by Figure 2 For example, the control shaft 420 rotates counterclockwise. For the two stirring members 440 located on the right side of the control shaft 420, the distance between the two stirring members 440 is large. As the control shaft 420 continues to rotate, the distance between the two stirring members 440 will decrease. Figure 2 After the state shown continues to rotate 180 degrees, the distance between the two stirring members 440 will be significantly reduced. When the powder in the processing tank 410 does not exceed the control shaft 420, the control shaft 420 continues to rotate, and the dust extraction assembly will enter the powder system. In the process of continued movement, the distance between the two stirring members 440 will increase again. During this process, the dust inlet valve 454 opens and the dust outlet valve 462 closes, and the piston 460 absorbs the gas and dust in the powder system through the mesh plate 451 and the dust inlet hole 453 of the extraction pipe 450 until the two stirring members 440 return to the original position. Figure 2 At this time, the extraction pipe 450 contains dust sucked from the bottom of the powder system.

[0067] As the extraction tube 450, filled with dust, continues to move along with the two agitators 440, the distance between the two agitators 440 begins to decrease. During this process, the dust inlet valve 454 closes and the dust outlet valve 462 opens, allowing the dust in the extraction tube 450 to be discharged from the dust outlet hole 461 and smoothly come into contact with the water mist in the treatment tank 410. This promotes the full settling of the dust at the bottom of the powder system.

[0068] After being processed by the post-processing mechanism 400, the dust in the powder system can be effectively controlled.

[0069] Further, please combine Figure 2 and Figure 9 In this embodiment, a stirring plate 480 is provided at one end of the driving rod assembly 430 away from the stirring member 440 , and a plate surface of the stirring plate 480 is provided parallel to the control shaft 420 .

[0070] One end of the second driving rod 432 away from the agitating member 440 is hinged to the agitating plate 480 , and a hinge axis of the second driving rod 432 on the agitating plate 480 is arranged parallel to the control shaft 420 .

[0071] The stirring plate 480 is provided with a slide groove 481 , which extends along the plate surface of the stirring plate 480 and is perpendicular to the hinge axis of the second driving rod 432 on the stirring plate 480 . The slide groove 481 is a T-shaped groove.

[0072] The end of the first driving rod 431 away from the agitator 440 is fixedly connected to a matching column 482, which is arranged parallel to the control shaft 420. The matching column 482 can be slidably matched with the slide groove 481, and the matching column 482 can be rotatably matched with the slide groove 481.

[0073] Through this design, the dust in the upper layer of the powder system can also be turned out by means of the stirring plate 480. Figure 2 As shown, when the stirring plate 480 moves into the powder system, since the front end of the stirring plate 480 in the direction of movement is "further away" from the control shaft 420, the stirring plate 480 can improve its ability to flip the powder system, making it easier to fully flip out the dust. When the stirring plate 480 moves above the powder system, that is, when the stirring plate 480 moves to the upper half of the processing tank 410, the front end of the stirring plate 480 in the direction of movement will be "closer" to the control shaft 420, which makes it less likely for the stirring plate 480 to "push" the already floating dust into the powder system, thereby helping the already floating dust to fully contact with the tax and absorb moisture.

[0074] Such a design can further improve the efficiency and adequacy of dust treatment.

[0075] Optionally, there are multiple drive rod groups 430, and the multiple drive rod groups 430 are evenly spaced along the circumference of the control shaft 420, and the multiple drive rod groups 430 are spaced along the axial direction of the control shaft 420. The number of drive rod groups 430 can be flexibly adjusted according to actual needs and will not be repeated here.

[0076] This embodiment also provides a feed processing system, which includes the above-mentioned crushing device 1000.

[0077] In summary, the pulverizing device 1000 provided in this embodiment of the present invention can effectively control dust generated during the material pulverization process, reducing dust safety and sanitation risks in the workshop and minimizing material loss. It is particularly suitable for pulverizing dry materials. The feed processing system can effectively control dust during the feed production process, reducing dust safety and sanitation risks in the workshop and minimizing raw material loss.

[0078] The foregoing description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that various modifications and variations of the present invention are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention are intended to be within the scope of protection of the present invention.
