Description

Technical Field

[0001] This utility model relates to the field of abrasive sand technology, specifically to a device for the regeneration and refining of abrasive sand. Background Technology

[0002] Ceramic slag, scientifically known as "fused ceramic sand," has advantages such as high temperature resistance, non-crushing, dust-free, spherical shape, high permeability, good filling properties, and no silica dust hazard. It is an environmentally friendly sand for green casting. After casting, fused ceramic slag enters the waste sand system. The existing treatment methods for this waste sand are: to treat it as solid waste or to magnetically separate the iron powder from the waste sand. The remaining waste sand is then regenerated by thermal or hot-wet methods and used directly, without recycling the fused ceramic slag. However, the existing fine-selection equipment has a complex structure and uses a gravity separator for screening. The gravity separator has a complex structure, slow screening speed, and is inconvenient to use. Utility Model Content

It not only has a better pearl sand refining effect, but also a faster pearl sand refining speed and is more convenient to use, which can effectively solve the problems in the background technology.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a pearl sand recycling and refining device, comprising a base, an inclined screening frame connected to the upper surface of the base by four legs, two corresponding sliding grooves inside the screening frame, the sliding grooves being located at the upper end of the screening frame, a screening mesh assembly inside the sliding grooves, elastic elements on both the front and rear sides of the lower surface of the screening mesh assembly, the elastic elements being located inside the two sliding grooves respectively, a conical guide hopper on the lower surface of the screening frame, a vibrating motor at one end of the lower surface of the screening frame, a discharge port with a conical side at the lower end of the screening frame, an air classifier on the upper surface of the base, the air classifier being located directly below the discharge port, and a blowing assembly on one side of the air classifier.

[0005] Furthermore, the upper surface of the base is provided with a screening material holding box, and the upper opening of the screening material holding box is located directly below the guide hopper.

The air outlet of the blower is connected to the inlet on one side of the rectangular blowing shell through a duct. The blower can blow air, and the rectangular blowing shell can blow the raw materials falling from the outlet. The housing can be divided into two hoppers by a partition. When the raw materials are light, they can be blown into the other hopper by the blowing assembly, thereby performing air separation on the raw materials.

[0008] Furthermore, the screening mesh assembly includes a screen support frame on which a screening mesh is disposed. The screening mesh can screen the raw materials, thereby filtering out dust inside the raw materials.

[0009] Furthermore, the elastic element includes a support strip, and springs are evenly arranged between the upper surface of the support strip and the lower surface of the screen support frame. When the vibrating motor vibrates, it can drive the screen support frame to vibrate, and the screen support frame can drive the screening screen to vibrate, thereby making the screening speed of the screening screen faster.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: when the vibrating motor vibrates, it can drive the screen support frame to vibrate, which in turn drives the screening screen to vibrate, thereby making the screening speed of the screening screen faster. The screening screen can screen the raw materials, thereby filtering the dust inside the raw materials.
