[0020] The present utility model will now be described in further detail with reference to the drawings. These drawings are all simplified schematic diagrams, only illustrating the basic structure of the present utility model in a schematic manner, so they only show the components related to the present utility model.

[0021] The following further details the embodiments of the present utility model with reference to the drawings:

[0022] Refer to Figure 1 andFigure 2 As shown, nano calcium carbonate, also known as ultra-fine calcium carbonate, can improve the rheology of plastic masterbatch, enhance its formability, and has the function of toughening and reinforcing when used as a plastic filler, improving the flexural strength, flexural modulus of elasticity, heat distortion temperature and dimensional stability of the plastic. At the same time, it also imparts heat retention to the plastic. In the processing of most existing nano calcium carbonate powders, due to different particle sizes, particles of different specifications will affect the effect on the masterbatch, and thus it is necessary to screen the particle size of the powder. To solve such problems, a nano calcium carbonate powder treatment device is proposed, including a processing frame 1. An inlet 12 for powder feeding is opened inside the bottom of the processing frame 1. The inlet 12 is gradually converged inward from top to bottom and is inclined. And a treatment tank 121 is extended and opened at the lower side of the inlet 12. A filter screen plate 2 for filtering powders that do not meet the particle size standard is provided at the bottom of the treatment tank 121. A processing member 3 is provided on one side of the filter screen plate 2. The processing member 3 includes guide chutes 13 opened on both sides of the treatment tank 121. Between the two guide chutes 13 and the treatment tank 121, push plates 31 for extruding and crushing the powders that do not pass through on the filter screen plate 2 are respectively provided. The two push plates 31 are slidably arranged away from or close to each other along the top surface of the filter screen plate 2. And a driving member 14 for driving the push plate 31 to slide is provided on one side of the push plate 31. A protective member 32 for protecting the processing process is provided on the upper side of the treatment tank 121; through the setting of the processing frame 1 and the inlet 12, the purpose of making the calcium carbonate powder pour in orderly for processing is achieved. And with the setting of the filter screen plate 2 in the treatment tank 121, powders that meet the particle size can pass through orderly, and powders that cannot pass effectively can be secondarily extruded and crushed by the processing member 3, ensuring that the powders can fall down in a state that meets the standard. And through the setting of the protective member 32, during the secondary extrusion of the powders, the bottom of the inlet 12 is in a closed state, so as to achieve the purpose of protecting the whole processing process.

[0023] It should be noted that the above filter screen plate 2 is arranged at the bottom of the treatment tank 121. After the powders input into the inlet 12 slide down orderly into the filter screen plate 2, the powders with qualified particle sizes will pass through orderly downward, while the powders with too large particle sizes cannot pass through the filter screen plate 2. At this time, in order to secondarily process this part of the powders, in this embodiment, the processing member 3 is set to achieve the secondary processing of the powders that do not pass through. Specifically, when the driving member 14 operates, the two push plates 31 approach each other and gradually extend to the upper side of the filter screen plate 2. At this time, the powders with too large particle sizes on the upper side of the filter screen plate 2 will be extruded and crushed, so that this part of the powders that cannot pass through the filter screen plate 2 will fall down orderly.

[0024] Further, the specific structure of the driving member 14 is as follows: The driving member 14 includes a driving cylinder 141 provided on one side of the processing frame 1. The output end of the driving cylinder 141 extends inward into the guide chute 13 and is provided on the side surfaces of the two push plates 31 away from each other. By operating the driving cylinder 141, its output end can start to extend, thereby pushing the push plate 31 to slide.

[0025] During the above processing, in order to prevent the powder in the above-mentioned feeding port 12 from falling downward into the space between the two push plates 31 away from each other, in this embodiment, the above requirements are achieved through the setting of the protective member 32. Specifically, the specific structure of the protective member 32 is as follows: The protective member 32 includes a baffle 321 that slides up and down along the feeding port 12. The size of the baffle 321 is adapted to the processing groove 121, and a telescopic cylinder 323 for driving the baffle 321 to slide vertically up and down is provided on the upper side of the baffle 321. The telescopic cylinder 323 is provided on the top of the processing frame 1. By operating the telescopic cylinder 323, the baffle 321 can start to slide downward until the baffle 321 is stuck at the bottom of the feeding port 12. At this time, the feeding channel of the feeding port 12 is closed, and an orderly processing process is carried out between the push plate 31 and the powder below the baffle 321.

[0026] It should also be noted that when the above-mentioned baffle 321 abuts downward against the bottom of the feeding port 12, at this time, the baffle 321 needs to be completely adapted to the bottom specifications of the feeding port 12. Here, the adaptation means that both the size and shape need to be the same, that is, it is necessary to ensure that the feeding port 12 cannot feed materials into the processing groove 121 at this time.

[0027] Additionally, in order to ensure that after the baffle 321 is reset upward, the powder on the upper side of the baffle 321 can fall outward into the feeding port 12 in an orderly manner. In this embodiment, a diversion plate 322 for diverting the powder retained on the upper side of the baffle 321 is provided on the upper side of the baffle 321. Through the setting of the diversion plate 322, it is possible to prevent the powder that subsequently enters the feeding port 12 from remaining on the baffle 321.

[0028] It is worth mentioning that in order to collect the powder passing through the filter mesh plate 2 in an orderly manner, in this embodiment, a receiving groove 11 for placing the powder is provided below the processing frame 1 at the position of the filter mesh plate 2. Through the setting of the receiving groove 11, the purpose of accommodating the powder that meets the particle size requirements in a stable environment can be achieved.

[0029] Further, some crushing spikes are also provided between the two push plates 31. The powder is processed twice by the crushing spikes, and this part of the structure is relatively common in the existing crushing structures, so it will not be elaborated here.

[0030] Moreover, in order to enable the filter mesh plate 2 to be quickly replaced and disassembled, in this embodiment, the filter mesh plate 2 is detachably connected to the bottom of the treatment tank 121, and a plurality of filter holes 21 for filtering powder are formed in the filter mesh plate 2; the detachable connection here can be snap connection or threaded connection, and the size specification of the filter holes 21 is the main factor determining the particle size of the passed powder.

[0031] It should be emphasized that the embodiments described in the present utility model are illustrative rather than restrictive. Therefore, the present utility model is not limited to the embodiments described in the specific implementation manners. Any other implementation manners obtained by those skilled in the art according to the technical solutions of the present utility model also fall within the scope of protection of the present utility model.
