Abstract
Description
Technical Field
[0001] The utility model relates to the field of silicon powder production equipment, in particular to a wear-resistant cyclone separator. Background Art
[0002] A cyclone separator is a device used for solid-gas separation. The working principle of a cyclone separator is to rely on the rotational motion caused by the tangential introduction of airflow to throw solid particles or liquid droplets with large inertial centrifugal force to the outer wall to separate, while the gas is discharged from the upper end of the cyclone separator. In the production of silicon powder, some dust will be generated in the workshop. For this dust recovery, a dust extraction device is generally used to extract the dust in the workshop and then transport it to the cyclone separator for solid-gas separation, and then the silicon powder is collected. The inner wall of the existing cyclone separator is very easy to wear due to the high-speed collision of particles. Therefore, the cyclone separator can only be scrapped after being worn to a certain extent, resulting in high cost. Therefore, it is particularly necessary to develop a wear-resistant cyclone separator to reduce the use cost of the cyclone separator. Summary of the invention
[0003] The utility model aims to provide a wear-resistant cyclone separator, which has the advantage of reducing the use cost of the cyclone separator.
[0004] The technical solutions adopted are as follows:
[0005] A wear-resistant cyclone separator comprises a cylinder, which comprises a cone and an air inlet section. The cone and the air inlet section are fixedly connected by bolts. A plurality of overlapping conical rings are arranged from the upper right to the bottom of the inner wall of the cone. The inner wall of the conical ring is sprayed with a wear-resistant coating. A pressure ring is detachably arranged on the inner upper end of the cone.
[0006] Preferably, the lower end of the conical ring is provided with an overlap.
[0007] Preferably, both the upper end surface and the lower end surface of the conical ring are provided with O-rings.
[0008] Preferably, the inner wall of the cone is vertically provided with a plurality of limit strips, and the outer wall of the conical ring is provided with a plurality of through grooves corresponding to the limit strips.
[0009] Preferably, there are four limit bars, and the four limit bars are evenly spaced apart.
[0010] Preferably, the pressure ring is connected to the upper end of the cone by a plurality of bolts.
[0011] Compared with the prior art, the beneficial effects are:
[0012] 1. The utility model utilizes a plurality of conical rings of different sizes to overlap and be installed on the inner wall of the cone. The silicon powder moving at high speed hits the inner wall of each conical ring instead of hitting the inner wall of the cone, thereby preventing the cone from being worn. When the inner wall of the conical ring is severely worn, only the severely worn conical ring needs to be replaced, thereby reducing the maintenance cost.
[0013] 2. The O-ring in the utility model improves the sealing performance between the tapered rings. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The present invention will be further described below in conjunction with specific embodiments. Figures 1 to 3 As shown:
[0019] Embodiment 1: A wear-resistant cyclone separator comprises a cylinder, the cylinder comprises a cone 1 and an air inlet section 2, the cone 1 and the air inlet section 2 are fixedly connected by bolts, a dust collecting hopper is arranged at the lower end of the cone 1, an exhaust pipe 3 is arranged at the upper end of the air inlet section 2, an air inlet pipe is arranged on the side of the air inlet section 2, and the gas containing silicon powder enters the air inlet section 2 from the air inlet pipe and then enters the cone 1.
[0020] A plurality of overlapping conical rings 4 are arranged on the inner wall of the cone 1 from the upper right to the bottom, and the inner wall of the conical ring 4 is sprayed with a wear-resistant coating. The wear-resistant coating is a prior art and will not be described here. A pressure ring 5 is detachably arranged on the upper end of the inner part of the cone 1. The pressure ring 5 is pressed on the upper end of the uppermost conical ring 4, so that the adjacent conical rings 4 are closely connected, and the sealing between the adjacent conical rings 4 is realized.
[0021] The high-speed moving silicon powder hits the inner wall of each conical ring 4 instead of hitting the inner wall of the cone 1, so that the cone 1 is protected from wear. When the inner wall of the conical ring 4 is severely worn, only the severely worn conical ring 4 needs to be replaced, which reduces maintenance costs.
[0022] Embodiment 2: A wear-resistant cyclone separator comprises a cylinder, the cylinder comprises a cone 1 and an air inlet section 2, the cone 1 and the air inlet section 2 are fixedly connected by bolts, a dust collecting hopper is arranged at the lower end of the cone 1, an exhaust pipe 3 is arranged at the upper end of the air inlet section 2, an air inlet pipe is arranged on the side of the air inlet section 2, and the gas containing silicon powder enters the air inlet section 2 from the air inlet pipe and then enters the cone 1.
[0023] A plurality of overlapping conical rings 4 are arranged from the upper right to the bottom of the inner wall of the cone 1, and the inner wall of the conical ring 4 is sprayed with a wear-resistant coating. The wear-resistant coating is a prior art and will not be described in detail here. A pressure ring 5 is detachably arranged on the upper end of the inner part of the cone 1. The pressure ring 5 is pressed on the upper end of the uppermost conical ring 4. The pressure ring 5 is connected to the upper end of the cone 1 by a plurality of bolts, so that the adjacent conical rings 4 are tightly connected to achieve the sealing between the adjacent conical rings 4. The lower end of the conical ring 4 is provided with an overlap 41, and the overlap 41 prevents silicon powder from entering the gap between the two conical rings 4. The upper end face and the lower end face of the conical ring 4 are both provided with O-rings, and the O-rings improve the sealing between the conical rings 4.
[0024] Four limit bars are vertically arranged on the inner wall of the cone 1, and four through grooves 6 corresponding to the limit bars are opened on the outer wall of the conical ring 4. The limit bars cooperate with the through grooves 6 to limit the conical ring 4. The high-speed moving silicon powder hits the inner wall of each conical ring 4 instead of hitting the inner wall of the cone 1, thereby preventing the cone 1 from being worn. When the inner wall of the conical ring 4 is severely worn, only the severely worn conical ring 4 needs to be replaced, thereby reducing the maintenance cost.
[0025] The specific working process is as follows: when performing solid-gas separation work, the gas containing silicon powder enters the air inlet section 2 from the inlet pipe and then enters the cone 1. The high-speed moving silicon powder in the cone 1 hits the inner walls of each conical ring 4 instead of hitting the inner wall of the cone 1, thereby preventing the cone 1 from being worn. When the inner wall of the conical ring 4 is severely worn, the cone 1 and the air inlet section 2 are separated, the pressure ring 5 is removed, and the severely worn conical ring 4 is replaced. Then the pressure ring 5 is reinstalled, and the cone 1 and the air inlet section 2 are fixed together with bolts.

Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
