Description

Technical field:

[0001] The utility model relates to the field of production and manufacturing of polysilicon, in particular to a dust removal hood for reducing dust. Background technology:

[0002] Polycrystalline silicon is a form of elemental silicon. When molten elemental silicon solidifies under supercooling conditions, silicon atoms are arranged into many crystal nuclei in the form of diamond lattices. If these crystal nuclei grow into grains with different crystal plane orientations, these grains will combine and crystallize into polycrystalline silicon.

[0003] A dust hood is usually provided at the material outlet of the polysilicon vibrating feeder to absorb the dust flying at the outlet. However, the existing dust hood, whether it has a folding edge or a blocking device or not, can only absorb a part of the dust particles during operation. In particular, when the dust is large and the dust requirements are very strict, the adsorption effect cannot reach the expected value.

[0004] Therefore, a new type of dust hood is needed to effectively absorb dust. Utility model content:

[0005] The utility model aims to provide a dust removal hood for reducing dust.

[0006] The utility model is implemented by the following technical solutions:

[0007] A dust removal hood for reducing dust comprises a hood body, a hook edge, an air intake port and an air exhaust port. The hook edge is fixedly installed on the outer wall of the bottom end of the hood body, and the hook edge is arranged at an inclination. A fixing plate is fixedly embedded at the top corner of the hood body, and the air intake port and the air exhaust port are arranged on the fixing plate. The air intake port and the air exhaust port are communicated with each other, and the angle between the air intake port and the air exhaust port is 45 degrees.

[0008] Preferably, a plurality of threaded holes are provided on the hook edge.

[0009] Preferably, a connecting pipe is fixedly connected to the air suction port, a sealing member is threadedly connected to one end of the connecting pipe, and a guide pipe is threadedly connected to one end of the sealing member.

[0010] The advantages of the utility model: the air extraction port and the air suction port are at a 45-degree angle, so they can get closer to the sucked material and completely suck it away to achieve the desired purpose; the hook edge also serves as a sealing structure for the adsorption object; the air extraction port is connected to a dust removal or vacuum cleaning device to suck away the sucked dust or particles; the structure is simple; the suction port of the object object through the cover body is infinitely close to the sucked material; the sealing and blocking effect of the hook structure is utilized to greatly improve the adsorption capacity of the dust or particles.

[0015] In the figure: cover body 1, hook edge 2, air inlet 3, air exhaust port 4, fixing plate 5, connecting pipe 6, sealing member 7, guide pipe 8. Specific implementation method:

[0016] like Figures 1 to 4 As shown, a dust removal hood for reducing dust comprises a hood body 1, a hook edge 2, an air intake port 3 and an air extraction port 4. The outer wall of the bottom end of the hood body 1 is fixedly installed with a hook edge 2, and the hook edge 2 is inclined. A fixing plate 5 is fixedly embedded at the top corner of the hood body 1, and an air intake port 3 and an air extraction port 4 are arranged on the fixing plate 5. The air intake port 3 and the air extraction port 4 are communicated with each other, and the angle between the air intake port 3 and the air extraction port 4 is 45 degrees, which can improve the adsorption capacity of dust particles, especially for local positions where dust is generated in non-standard packaging equipment. The air extraction port and the air intake port are at an angle of 45 degrees, which can better approach the adsorbed material and completely suck it away to achieve the desired purpose. The hook edge 2 also serves as a structure for sealing the adsorption object. The air extraction port 4 is connected to a dust removal or vacuum cleaning device to suck away the absorbed dust or particles. The structure is simple, and the suction port part of the target object of the hood body 1 is infinitely close to the adsorbed material, and the sealing and blocking effect of the hook structure is utilized, thereby greatly improving the adsorption capacity of the dust or particles.

[0017] A plurality of threaded holes are provided on the hook edge 2, and bolts are inserted into the threaded holes to fix the hook with the bracket or equipment.

[0018] A connecting pipe 6 is fixedly connected to the air exhaust port 4. The inclination angle of the connecting pipe 6 is connected to the inclination angle of the air exhaust port 4 in order to keep the angle of wind force connected to avoid affecting the wind force. Similarly, a seal 7 is screwed on one end of the connecting pipe 6. The seal 7 plays a sealing and guiding role. The seal 7 also maintains the same inclination angle as the connecting pipe 6. A guide tube 8 is screwed on one end of the seal 7. The guide tube 8 plays a guiding role. During installation, after the input end hose of the vacuum cleaner is inserted into the guide tube 8, the seal 7 is used to lock and fix the connection and seal, so that the wind is drawn along the preset angle, thereby ensuring the overall adsorption effect.
