Description

Technical Field

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

[0002] Sand making refers to the sand processed by a sand making machine and other auxiliary 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 prior art, the mechanism of the sand making and powder selection device is relatively simple, and the material is not loose enough in the dust removal component, resulting in an unsatisfactory dust removal effect and affecting the sand making quality. Therefore, we propose a power-free powder selection structure integrating a sand making device. Summary of the Utility Model

[0004] The utility model provides a power-free powder selection structure integrating a sand making device, which solves the above technical problems.

[0005] The solution of the utility model to the above technical problems is as follows: A power-free powder selection structure integrating a sand making device includes a horizontally arranged dust removal hopper. A plurality of guide plates are rotatably installed on the inner side wall of the dust removal hopper. The plurality of guide plates are arranged at equal intervals. The guide plates are connected with a rotation control mechanism. An air outlet is formed on one side of the dust removal hopper. An L-shaped air outlet pipe is fixedly installed at the air outlet. An air inlet pipe is fixedly communicated with the side wall of the dust removal hopper far away from the air outlet pipe. A plurality of inclined adjusting pieces are fixedly installed on the inner side wall of the air inlet pipe. The plurality of adjusting pieces are arranged at equal intervals.

[0006] Preferably, the rotation control mechanism includes a rotation handle vertically arranged outside the dust removal hopper. The rotation handle is fixedly connected with the guide plate through a connecting shaft that rotates through the dust removal hopper.

[0007] Preferably, a material receiving groove is formed at the lower part of the dust removal hopper.

[0008] Preferably, a vibrating screen is fixedly installed at the upper part of the dust removal hopper. The vibrating screen is inclined. A feed inlet is formed at the upper end of the vibrating screen.

[0009] The beneficial effects of the utility model are as follows:

[0010] The device is provided with a vibrating screen. When the material screened by the vibrating screen enters the dust removal hopper, the dust in the material is separated by the air flow entering from the right air inlet pipe of the dust removal, and then a vortex air cyclone is formed by a plurality of guide plates in the dust removal hopper, enhancing the dust separation efficiency. The dust is discharged from the left air outlet pipe, while the material is discharged from the lower material receiving groove, which is highly practical.

[0018] The following Figures 1-3 describes the principles and features of the present utility model. The examples given are only used to explain the present utility model and are not used to limit the scope of the present utility model. In the following paragraphs, the present utility model will be described more specifically by way of example with reference to the accompanying drawings. According to the following description and the claims, the advantages and features of the present utility model will be clearer. It should be noted that the drawings are all in a very simplified form and use non-precise scales, and are only used to conveniently and clearly assist in explaining the purpose of the embodiments of the present utility model.

[0019] As Figures 1-3As shown in the figure, a power-free powder selection structure of an integrated sand making device of the present utility model includes a dust removal hopper 1 arranged horizontally. A material receiving groove 8 is opened at the lower part of the dust removal hopper 1. A plurality of guide plates 2 are rotatably installed on the inner side wall of the dust removal hopper 1. The plurality of guide plates 2 are arranged at equal intervals. The guide plates 2 can disperse the materials to a certain extent and enhance the dust removal effect. The guide plates 2 are connected with a rotation control mechanism. An air outlet 3 is opened on one side of the dust removal hopper 1. An L-shaped air outlet pipe 4 is fixedly installed at the air outlet 3. An air inlet pipe 5 is fixedly communicated with the side wall of the dust removal hopper 1 far away from the air outlet pipe 4. A plurality of inclined adjustment pieces 6 are fixedly installed on the inner side wall of the air inlet pipe 5. A plurality of adjustment pieces 6 are arranged in the air inlet pipe 5 to change the flow direction of the air flow. The plurality of adjustment pieces 6 are arranged at equal intervals. By arranging a plurality of guide plates 2, the device forms an irregular air flow direction by using the guide plates 2, and enhances the dust removal effect of the device.

[0020] Specifically, the rotation control mechanism includes a rotation handle 7 arranged vertically outside the dust removal hopper 1. The rotation handle 7 is fixedly connected with the guide plate 2 through a connecting shaft that rotates through the dust removal hopper 1. Rotating the external rotation handle 7 can drive the internal guide plate 2 to rotate synchronously, and adjusting the angle of the guide plate 2 can change the flow direction of the air flow.

[0021] More specifically, a vibrating screen 9 is fixedly installed at the upper part of the dust removal hopper 1. The vibrating screen 9 is arranged obliquely. A feed inlet 10 is opened at the upper end of the vibrating screen 9. The vibrating screen 9 is used for vibrating and screening the materials.

[0022] Working principle:

[0023] During use, the materials are fed into the feed inlet 10. The vibrating screen 9 screens the materials. The materials screened by the vibrating screen 9 enter the dust removal hopper. The external fan pipeline is connected with the air inlet pipe 5. A negative air pressure is formed inside the dust removal hopper 1 driven by the external fan, so that the air forms an irregular air flow direction from the air inlet pipe 5 of the dust removal hopper 1 under the action of the guide plate. The angle of the guide plate 2 is adjusted by adjusting the handle assembly to change the flow direction of the air flow. Among them, the guide plate 2 can also disperse the materials to a certain extent and enhance the dust removal effect. The finished products after dust removal are discharged through the material receiving groove 8 at the lower end of the dust removal hopper 1.

[0024] The above is only the preferred embodiment of the present utility model, and it does not impose any form of limitation on the present utility model; any ordinary technical personnel in the industry can smoothly implement the present utility model according to the instructions in the attached drawings and the above description; however, any slight changes, modifications and evolutions made by those skilled in the art within the scope of the technical solution of the present utility model by using the technical content disclosed above are all equivalent embodiments of the present utility model; at the same time, any equivalent changes, modifications and evolutions made to the above embodiments based on the essential technology of the present utility model still fall within the protection scope of the technical solution of the present utility model.
