Description

Technical Field

[0001] This utility model relates to the field of anti-wear technology, and in particular to an anti-wear device for the target area of ​​a cyclone separator. Background Technology

[0002] A cyclone separator is a device used for separating gas-solid or liquid-solid systems. Its working principle relies on the rotational motion caused by the tangential introduction of airflow, which throws solid particles or liquid droplets with significant inertial centrifugal force towards the outer wall surface, separating them.

[0003] The target area of ​​a cyclone separator is located at the intersection of the arc surface of the cyclone cylinder and the inlet flue. In this area, the flue gas carrying particles directly impacts the cylinder wall of the cyclone separator, generating a strong impact. Furthermore, the material orientation changes in this area, making the target area prone to wear. Therefore, a wear-resistant device for the target area of ​​a cyclone separator is needed to meet people's needs. Utility Model Content

[0004] The purpose of this invention is to provide a wear-resistant device for the target area of ​​a cyclone separator to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a cyclone separator target area anti-wear device, comprising a housing, a cone, an air inlet, an air outlet, and a slag discharge port. The housing is cylindrical, and the cone is connected to the bottom of the housing, arranged in a manner where the inner diameter gradually decreases from top to bottom. The air inlet is a square pipe welded to the outer wall of the housing and arranged tangentially to the housing. The air outlet is a circular pipe welded to the outer and inner top of the housing. The slag discharge port is arranged at the bottom of the cone. A sleeve is rotatably connected to the circular pipe and arranged inside the housing. Several blades are arranged evenly in a circumferential pattern on the outer wall of the sleeve, and each blade corresponds to the position of the air inlet.

[0006] Preferably, the circular pipe has an annular groove on the outer wall of the box body, and the sleeve is rotatably adapted to the annular groove.

[0007] Preferably, the thickness of the end of the blade connected to the sleeve is less than the thickness of the blade away from the end connected to the sleeve, and the inclined surface is closer to the air inlet.

[0008] Preferably, the thickness of the blade near the top of the housing is greater than the thickness of the blade away from the top of the housing, and the inclined surface is on the side near the air inlet.

[0009] Preferably, a first rubber strip is provided on the inner wall of the box. The first rubber strip is arranged vertically on the tangential inner wall at the connection between the square pipe and the box, and each blade can contact the first rubber strip.

[0010] Preferably, a second rubber strip is provided on the inner wall of the box, and the second rubber strip is arranged vertically at the end of the box away from the square pipe.

[0011] Preferably, the end of the blade facing away from the air inlet is inclined, and the cross-sections of the first rubber strip and the second rubber strip are both trapezoidal.

[0012] The beneficial effects of this utility model are:

[0013] In this invention, the rotating connection of the sleeve and the connection of several blades to the sleeve allow the flue gas carrying particles to be shielded by the blades when entering the housing through the air inlet. This prevents the particles from directly impacting the target area of ​​the cyclone separator, providing a certain degree of protection to the target area. Furthermore, the impact of the flue gas on the blades causes the sleeve to rotate, effectively reducing the impact force of the flue gas, lowering the speed of the flue gas during discharge, and buffering the impact force. This reduces the impact force generated by the flue gas and particles at the target area, thereby achieving an anti-wear effect at the target area.

[0014] In this invention, the addition of a first rubber strip improves the airtightness between the blade and the housing at the connection between the air inlet and the housing, providing a shield for the flue gas and particles, preventing the flue gas carrying particles from directly impacting the target area. Furthermore, the friction between the first rubber strip and the blade provides a certain resistance to the rotation of the blade under the action of the flue gas flow, and provides a deceleration effect for the rotation of the sleeve driven by the blade, further reducing the flue gas discharge speed and further improving the anti-wear effect at the target area.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Reference Figure 1-4 A cyclone separator target area anti-wear device includes a housing 1, a cone 2, an air inlet 3, an air outlet 4, and a slag discharge port 5. The housing 1 is cylindrical, and the cone 2 is connected to the bottom of the housing 1. The cone 2 is arranged in a gradually decreasing inner diameter from top to bottom. The air inlet 3 is a square pipe welded to the outer wall of the housing 1 and is arranged tangentially to the housing 1. The air outlet 4 is a circular pipe welded to the outside and inside of the top of the housing 1. The slag discharge port 5 is arranged at the bottom of the cone 2. A sleeve 6 is rotatably connected to the circular pipe. The sleeve 6 is arranged inside the housing 1. Several blades 7 are provided on the outer wall of the sleeve 6. The blades 7 are evenly arranged in a circumferential shape, and the positions of the blades 7 correspond to the positions of the air inlet 3.

[0022] Through the rotating connection of the sleeve 6 and the connection of several blades 7 to the sleeve 6, when the flue gas carrying particles enters the housing 1 through the air inlet 3, the flue gas is blocked by the blades 7, which can prevent the particles carried by the flue gas from directly impacting the target area of ​​the cyclone separator, thus providing a certain degree of protection to the target area. Furthermore, the impact of the flue gas entering the housing on the blades 7 causes the sleeve 6 to rotate, effectively reducing the impact force of the flue gas, reducing the speed of the flue gas when it enters the housing, and buffering the impact force of the entering flue gas, thereby reducing the impact force generated by the flue gas and particles at the target area, thus achieving an anti-wear effect at the target area.

[0023] Specifically, in this embodiment, a circular groove 8 is provided on the outer wall of the circular pipe inside the housing 1. The sleeve 6 is rotated and adapted to the groove 8 to provide axial positioning for the sleeve 6, ensuring that the sleeve 6 and the blade 7 correspond to the positions of the air inlet 3 and the target area.

[0024] Specifically, in this embodiment, the thickness of the end of the blade 7 connected to the sleeve 6 is less than the thickness of the end of the blade 7 away from the connection end of the sleeve 6. The inclined surface is close to the side of the air inlet 3, so that when the flue gas carrying particles impacts the blade 7, the inclined surface can effectively reduce the amount of particles flowing towards the side of the blade 7 away from the connection end of the sleeve 6, thereby reducing the impact of particles and flue gas on the target area and guiding the particles and flue gas towards the connection end of the blade 7 and the sleeve 6.

[0025] Specifically, in this embodiment, the thickness of the blade 7 near the top of the housing 1 is greater than the thickness of the blade 7 away from the top of the housing 1, and the inclined surface is close to the side of the air inlet 3. The inclined surface causes the smoke and particles to tilt downward, thereby guiding the smoke and particles to produce a spiral effect.

[0026] Specifically, in this embodiment, a first rubber strip 9 is provided on the inner wall of the housing 1. The first rubber strip 9 is arranged vertically on the tangential inner wall at the connection between the square pipe and the housing 1. Each blade 7 can contact the first rubber strip 9. By adding the first rubber strip 9, the airtightness between the blade 7 and the housing 1 at the connection between the air inlet 3 and the housing 1 is improved, providing shielding for the flue gas and particles, preventing the flue gas carrying particles from directly impacting the target area. Furthermore, the friction between the first rubber strip 9 and the blade 7 provides a certain resistance to the rotation of the blade 7 under the action of the flue gas flow, and provides a deceleration effect for the rotation of the sleeve 6 driven by the blade 7, further reducing the flue gas discharge speed and further improving the anti-wear effect at the target area.

[0027] Specifically, in this embodiment, a second rubber strip 10 is provided on the inner wall of the housing 1. The second rubber strip 10 is arranged vertically at the end of the housing 1 away from the square pipe, which further reduces the rotation speed of the sleeve 6 driven by the blade 7, thereby providing a deceleration effect for the discharge speed of flue gas and particles and enhancing the anti-wear effect of the target area.

[0028] Specifically, in this embodiment, the end of the blade 7 facing away from the air inlet 3 is inclined, and the cross-sections of the first rubber strip 9 and the second rubber strip 10 are both trapezoidal. This is beneficial for the blade 7 to compress the first rubber strip 9 and the second rubber strip 10 under the guidance of the inclined surface when they come into contact, and to provide frictional deceleration.

[0029] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
