Description

Technical Field

[0001] The utility model relates to the technical field of sand making and powder selection, in particular to a powder selection structure of an integrated sand making device. Background Art

[0002] Sand making refers to sand processed by sand making machines and other ancillary equipment. The finished product is more regular and can be processed into sand of different rules and sizes according to different process requirements.

[0003] However, in the existing technology, sand making materials need to be dust separated before use, and the conventional powder selection structure has a short processing time for the material. The processing time of the material in the powder selection mechanism is not enough to separate the dust in the material, resulting in unsatisfactory dust separation effect. For this reason, we propose a powder selection structure for an integrated sand making device. Utility Model Content

[0004] The utility model provides a powder selection structure of an integrated sand making device, which solves the above-mentioned technical problems.

[0005] The solution of the utility model to solve the above technical problems is as follows: a powder selection structure of an integrated sand making device, including a powder selection chassis, the powder selection chassis is funnel-shaped, and two stepped inclined baffles are obliquely arranged in the powder selection chassis, the stepped inclined baffles are fixedly connected to the inner wall of the powder selection chassis, one end of the upper part of the powder selection chassis is fixedly connected to a dust pipe, an end of the powder selection chassis close to the dust pipe is vertically fixedly installed with a vortex baffle, an end of the powder selection chassis away from the dust pipe is fixedly installed with an air inlet, a plurality of partition plates are vertically fixedly installed on the inner wall of the air inlet, and an air inlet pipe is fixedly connected to the end of the air inlet.

[0006] Preferably, a feed port is provided on the upper portion of the powder selection machine case, a cover is threadedly mounted on the inner side wall of the feed port, and a handle is fixedly mounted on the upper end surface of the cover.

[0007] Preferably, a connecting pipe is fixedly connected to the lower part of the powder selection machine box.

[0008] The beneficial effects of the utility model are:

[0009] This device sets an additional eddy current baffle in the powder selection machine box. The material first enters the powder selection machine box from the feed port of the powder selection machine, and then breaks up and prolongs the residence time when passing through the stepped inclined baffles. The air flow enters the material through the two baffles from the air inlet for dust separation, and finally forms a vortex wind vortex at the eddy current baffle to ensure more effective dust separation, and the dust separation effect is better and ideal.

[0010] The above description is only an overview of the technical solution of the present invention. In order to more clearly understand the technical means of the present invention and to implement it according to the contents of the description, the following is a detailed description of the preferred embodiments of the present invention with the accompanying drawings.

[0017] The following is combined with Figure 1-3 The principles and features of the present invention are described, and the examples provided are intended only to illustrate the present invention and are not intended to limit the scope of the present invention. The following paragraphs describe the present invention in more detail by way of example with reference to the accompanying drawings. The advantages and features of the present invention will become more apparent from the following description and claims. It should be noted that the drawings are greatly simplified and not to exact scale, and are intended solely to facilitate and clearly illustrate the embodiments of the present invention.

[0018] Example 1

[0019] like Figure 1-3As shown, the utility model is a powder selection structure of an integrated sand making device, including a powder selection box 1, the powder selection box 1 is funnel-shaped, and two stepped inclined baffles 2 are tiltedly arranged in the powder selection box 1, the stepped inclined baffles 2 are fixedly connected to the inner wall of the powder selection box 1, one end of the upper part of the powder selection box 1 is fixedly connected to a dust pipe 3, an end of the powder selection box 1 close to the dust pipe 3 is vertically fixedly installed with an eddy current baffle 4, and an end of the powder selection box 1 away from the dust pipe 3 is fixedly installed with an air inlet 5, and the air inlet 5 is fixedly installed in the air inlet 5. Multiple partition plates 6 are fixedly installed vertically on the wall. Multiple partition plates 6 are set to ensure that the air entering the powder selection box 1 is evenly covered in all areas of the powder selection box 1. The end of the air inlet 5 is fixed with an air inlet pipe 7. This device breaks up the material entering the powder selection box 1 by setting two stepped inclined deflectors 2 and cooperating with the vortex baffle 4. At the same time, the residence time of the material in the powder selection box 1 is prolonged, so that the material and dust separation is more thorough, and a vortex wind vortex is formed at the vortex baffle 4 to ensure effective separation of dust.

[0020] Specifically, a feed port 8 is opened on the upper part of the powder selection machine chassis 1, and a cover 9 is threadedly installed on the inner side wall of the feed port 8. A handle is fixedly installed on the upper end surface of the cover 9. The handle is provided to make the rotation opening or closing of the cover 9 more labor-saving and convenient. The feed port 8 can be connected to an external material conveying pipeline, and the material can also be directly poured in to facilitate feeding.

[0021] More specifically, a connecting pipe 10 is fixedly connected to the lower part of the powder selection machine box 1, and the connecting pipe 10 is connected to other processing mechanisms to facilitate subsequent processing of the material.

[0022] Working principle:

[0023] When in use, open the cover 9, pass the material, connect the air inlet pipe 7 to the external fan, and start the fan to blow air. The fan blows air into the powder selection box 1, and cooperates with the stepped inclined baffle and the vortex baffle 4 to separate the material and the dust. As the material stays in the powder selection box 1, the dust in the material is separated from the material, and the dust is discharged through the dust pipe 3. After the dust is discharged, turn off the external fan, and let the material slowly fall into the lower connecting pipe 10, and use the connecting pipe 10 to transport the material.

[0024] The above are only preferred embodiments of the present invention and do not constitute any form of limitation to the present invention. Any ordinary technician in this industry can smoothly implement the present invention as shown in the drawings and described above. However, any equivalent changes, modifications and evolutions made by technicians familiar with this profession without departing from the scope of the technical solution of the present invention using the technical content disclosed above are all equivalent embodiments of the present invention. At the same time, any equivalent changes, modifications and evolutions made to the above embodiments based on the essential technology of the present invention are still within the scope of protection of the technical solution of the present invention.
