Description

Technical Field

[0001] This utility model relates to the field of cyclone separators, and in particular to a multi-stage high-efficiency cyclone separator. Background Technology

[0002] A cyclone separator is a device that uses centrifugal force to separate solid particles or droplets from dust-laden gas or liquid. It is widely used in dust treatment, gas purification, and dust removal systems.

[0003] A search revealed Chinese Patent Publication No. CN220836132U, which discloses a high-efficiency multi-stage cyclone separator. The separator includes a lower housing, with female connectors fixedly connected to the front and rear positions of the bottom of the lower housing's inner diameter. A fixed shell is located at the bottom of the lower housing, with male connectors fixedly connected to the front and rear positions of the top of the fixed shell's inner diameter. A dust-blocking blade is fixedly connected to the center of the fixed shell's inner diameter. An upper housing is connected through and fixedly to the top of the lower housing, and a top cover is fixedly connected to the top of the upper housing. An air outlet pipe is connected through and fixedly to the center of the top of the top cover. In this invention, when the cyclone rotates within the lower housing's inner diameter, the gas rotates downwards. Larger particles in the gas are separated along the inner wall of the lower housing due to centrifugal force. The fixed shell rotates, and the male connectors engage with the female connectors, allowing larger dust particles to flow into the fixed shell through the gaps between the dust-blocking blades.

[0004] The aforementioned device, while able to block particulate matter by setting up dust-blocking blades, suffers from several drawbacks. If the dust-blocking blades are too densely arranged, they can obstruct the discharge when there are many particles. If the dust-blocking blades are too sparsely arranged, they cannot effectively block the particles, making the device impractical. Therefore, a multi-stage high-efficiency cyclone separator is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a multi-stage high-efficiency cyclone separator, which aims to improve the existing technology where if the dust baffles are set too densely, it will cause obstruction of material discharge when there are many particles, and if the dust baffles are set too sparsely, they will not be able to block the particles well, making it impractical.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a multi-stage high-efficiency cyclone separator, comprising a shell, a secondary filtration assembly disposed in the middle of the shell, a blocking mechanism disposed in the lower part of the shell, and multiple support legs fixedly connected to the outer wall of the shell; the blocking mechanism includes a first guide member and a second guide member, the first guide member including a conduit, a guide ring fixedly connected to the top of the conduit, the guide ring being funnel-shaped with an upper diameter larger than a lower diameter, the second guide member including a guide cover, the guide cover being umbrella-shaped with a smooth top, a connecting rod fixedly connected to the bottom of the guide cover, and fixing plates fixedly connected to the front and rear sides of the lower part of the outer wall of the connecting rod, the fixing plates being fixedly connected to the inner wall of the conduit.

[0007] As a further description of the above technical solution:

[0008] A rubber ring is fixedly connected to the upper part of the guide ring, and the rubber ring is in contact with the inner wall of the conduit.

[0009] As a further description of the above technical solution:

[0015] As a further description of the above technical solution:

[0016] The secondary filtration assembly includes two connecting rings, and a telescopic tube is fixedly connected between the two connecting rings.

[0022] 1.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Reference Figures 1-3 This utility model provides an embodiment of a multi-stage high-efficiency cyclone separator, including a shell 1, which is the housing of the cyclone separator. An air inlet pipe 11 is fixedly connected to the upper right side of the shell 1, which is used to send gas containing particles into the shell 1. A secondary filter assembly 3 is provided in the middle of the shell 1, which is used to perform secondary filtration on the filtered gas to better separate the gas from the solid. A blocking mechanism 2 is provided in the lower part of the shell 1, which is used to guide and block falling solid particles to reduce the upward movement of particles by the gas. Multiple support legs 4 are fixedly connected to the outer wall of the shell 1 to support the separator. An air outlet pipe 12 is fixedly connected through the middle of the top surface of the shell 1 to facilitate the discharge of filtered gas. A discharge pipe 13 is fixedly connected to the lower part of the shell 1 to facilitate the discharge of separated particles. A mounting base 21 is threadedly connected to the discharge pipe 13.

[0034] like Figures 4-6As shown, the blocking mechanism 2 includes a first guide member 22 and a second guide member 23. The first guide member 22 includes a conduit 221, which is used to feed materials. A guide ring 222 is fixedly connected to the top of the conduit 221. The guide ring 222 is funnel-shaped with an upper diameter larger than a lower diameter, and is used to guide the particles downward. The second guide member 23 includes a guide cover 233, which is used to guide the particles to the guide ring 222. The guide cover 233 is umbrella-shaped with a smooth top. A connecting rod 231 is fixedly connected to the bottom of the guide cover 233, and is used to support the guide cover 233. The lower outer wall of the connecting rod 231 is fixedly connected to the front and rear sides with fixing plates 232, which are used to connect the second guide member 23 and the first guide member 22. The fixing plates 232 are fixedly connected to the inner wall of the guide tube 221. The upper part of the guide ring 222 is fixedly connected with a rubber ring 223, which is used to seal the gap between the processing guide ring 222 and the discharge pipe 13. The rubber ring 223 contacts the inner wall of the guide tube 221. The blocking mechanism 2 also includes a mounting base 21, which is used to facilitate the disassembly and assembly of the blocking mechanism 2. The guide tube 221 and the mounting base 21 are connected through and fixedly connected.

[0035] Furthermore, the secondary filtration assembly 3 includes two connecting rings 31 for connecting various components. A telescopic tube 33, which may be made of rubber or other materials, is fixedly connected between the two connecting rings 31 to facilitate the connection between the two connecting rings 31 and allows for a certain degree of expansion and contraction. A filter screen 36 is fixedly connected to the middle of the lower connecting ring 31 for secondary gas separation and filtration. An installation tube 32 is fixedly connected to the top of the upper connecting ring 31 to facilitate the connection between the secondary filtration assembly 3 and the air outlet pipe 12. The installation tube 32 is threadedly connected to the air outlet pipe 12. Multiple positioning rods 34 are fixedly connected to the top of the lower connecting ring 31 to restrict the movement direction of the lower connecting ring 31, allowing it to move only up and down. The positioning rods 34 pass through and slide on the upper connecting ring 31. A spring 35 is fixedly connected between the two connecting rings 31 and is sleeved on the outside of the positioning rods 34 to facilitate movement and vibration of the lower connecting ring 31.

[0036] Working principle: During use, gas containing solid particles enters the outer casing 1 through the air inlet pipe 11 and forms a cyclone on the inner wall of the outer casing 1. The particles mixed in the gas will separate from the gas under the action of centrifugal force and gravity. The particles will fall to the lower part of the outer casing 1, while the gas will be sent out through the air outlet pipe 12 in the middle of the outer casing 1. When the particles in the gas fall down onto the guide cover 233, the guide cover 233 will guide the particles to the guide ring 222, and the guide ring 222 will guide the particles to the conduit 221, thereby sending them out of the outer casing 1. Since the guide cover 233 is an umbrella shape with a rounded top surface, when the particles move upward, they will be blocked by the guide cover 233. Since the guide ring 222 is funnel-shaped, the particles falling on the guide ring 222 will be accelerated and sent to the conduit 221 and sent out, thereby achieving the purpose of preventing the particles from moving upward.

[0037] Meanwhile, when the gas passes through the air outlet 12, it will first be filtered by the filter screen 36, thereby further filtering out any particles that may be mixed in the gas. During the gas flow, the force generated by the gas flow will push the lower connecting ring 31 to move upward. Since the connecting ring 31 is connected to the upper positioning rod 34 through the positioning rod 34 and the spring 35, when the lower connecting ring 31 is pushed upward, the spring 35 will generate a reaction force on the lower connecting ring 31, thereby causing the lower connecting ring 31 to vibrate, so as to prevent particles from clogging the filter screen 36.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
