Description

Technical Field

[0001] The utility model relates to the field of cyclone dust collectors, in particular to a low-resistance and high-efficiency cyclone dust collector. Background Art

[0002] A cyclone dust collector is a dust removal device that uses the centrifugal force generated by a rotating airflow to separate dust particles from a dust-containing airflow.

[0003] The working principle is as follows: dust-laden gas enters the space between the outer shell and the exhaust pipe of the cyclone dust collector from the air inlet pipe at a high speed along the tangential direction, forming an external vortex that rotates downward. In the external vortex, the dust particles in the gas are thrown to the wall of the device under the action of centrifugal force, and move downward along the wall. After reaching the bottom of the cone, they rotate upward along the axis, forming an internal vortex, and finally discharged through the exhaust pipe.

[0004] For example, in industrial production, after the dust-containing exhaust gas enters the cyclone dust collector, the heavier dust particles are quickly thrown toward the inner wall of the dust collector due to the centrifugal force and fall into the ash hopper under the action of gravity. The smaller dust particles may move upward with the inner vortex, but due to the continuous centrifugal force, they will eventually be separated.

[0005] The separation effect of the cyclone dust collector mainly depends on the centrifugal force, which is related to factors such as the rotation speed of the airflow, the mass and particle size of the dust particles. Generally speaking, the faster the rotation speed, the greater the mass of the dust particles, and the larger the particle size, the greater the centrifugal force and the better the separation effect.

[0006] When the dust-laden gas directly enters the dust collector, a high-speed concentrated airflow will be formed in a local area inside the dust collector, resulting in increased local resistance and reduced working efficiency of the dust collector. Utility Model Content

[0007] The purpose of the utility model is to provide a low-resistance and high-efficiency cyclone dust collector to solve the defects mentioned in the above background technology.

[0009] Preferably, a sealing gasket is installed between the docking seat and the fixing seat, and the docking seat and the fixing seat are densely connected through the sealing gasket.

[0010] Preferably, eight groups of through holes are evenly opened on the outer sides of the fixing seat and the sealing gasket, and eight groups of screw holes are evenly opened on the surface of the docking seat, and the fixing bolts pass through the through holes on the fixing seat and the sealing gasket in turn and are screwed and fixed inside the screw holes.

[0011] Preferably, a through hole is provided in the middle of the fixing seat, and the through hole is adapted to the size of the flow equalizing tube, and the flow equalizing tube is inserted into the inside of the through hole.

[0012] Preferably, four groups of assembly grooves are evenly opened on the surface of the fixing seat, and four groups of assembly plates are evenly fixed on the top of the flow equalizing cylinder.

[0013] Preferably, the distances between two adjacent groups of flow balancing tubes are consistent, and the length of the flow balancing tube is greater than the thickness of the bottom plate of the flow balancing tube.

[0014] Compared with the prior art, the beneficial effects of the utility model are as follows: the gas impacts the inside of the flow equalizing cylinder and is ejected from the ends of multiple groups of flow equalizing tubes at the bottom of the flow equalizing cylinder, so that the dust-laden gas can evenly enter the inside of the dust collector body. The flow guide component significantly improves the airflow distribution, and can make the dust-laden gas more evenly distributed before entering the cyclone dust collector. Through the action of the flow guide component, the airflow can enter the dust collector at a relatively uniform speed and distribution, reducing the resistance caused by excessive local airflow velocity; the airflow inside the dust collector will flow more smoothly, reducing the generation of local eddies and turbulence.

[0021] See also Figure 1-5 The utility model provides a low-resistance and high-efficiency cyclone dust collector, including a dust collector body 1, a dust inlet pipe 2 is fixedly installed on the outer side of the upper part of the dust collector body 1, and a connecting frame 4 is welded and fixed at the end of the dust inlet pipe 2, and the connecting frame 4 is adapted to the size of a positioning seat 5, and the positioning seat 5 covers the surface of the connecting frame 4 and is fixed by multiple groups of bolts, and a dust inlet frame 3 is welded and fixed to the outer side of the positioning seat 5, and a flow guide component 6 is installed between the dust inlet frame 3 and the positioning seat 5, and the flow guide component 6 includes a docking seat 61 fixed to the end of the dust inlet pipe 2, and the surface of the docking seat 61 covers the fixed seat 64, and a flow equalizing tube 66 is fixedly installed on the fixed seat 64, and a plurality of groups of flow equalizing tubes 661 are evenly arranged on the bottom plate surface of the flow equalizing tube 66.

[0022] Working principle: The dust-laden gas that needs to be dust-removed enters the dust inlet pipe 2 from the dust inlet frame 3 through the guide component 6. The gas impacts the inside of the flow equalizing tube 66 and is ejected from the ends of the multiple groups of flow equalizing tubes 661 at the bottom of the flow equalizing tube 66, so that the dust-laden gas can evenly enter the dust collector body 1. The guide component 6 significantly improves the airflow distribution, and can make the dust-laden gas more evenly distributed before entering the cyclone dust collector. Through the action of the guide component 6, the airflow can enter the dust collector at a relatively uniform speed and distribution, reducing the resistance caused by the excessive local airflow velocity; the airflow inside the dust collector will flow more smoothly, reducing the generation of local eddies and turbulence.

[0023] As a preferred implementation, a sealing gasket 62 is installed between the docking seat 61 and the fixing seat 64 , and the docking seat 61 and the fixing seat 64 are densely connected through the sealing gasket 62 .

[0024] Eight groups of through holes are evenly formed on the outer sides of the fixing seat 64 and the sealing gasket 62, and eight groups of screw holes are evenly formed on the surface of the docking seat 61. At the same time, the fixing bolts pass through the through holes on the fixing seat 64 and the sealing gasket 62 in turn and are screwed and fixed inside the screw holes.

[0025] As a preferred implementation, a through hole 65 is opened in the middle of the fixing seat 64 , and the through hole 65 is adapted to the size of the flow equalizing tube 66 , and the flow equalizing tube 66 is inserted into the through hole 65 .

[0026] Four groups of assembly grooves 63 are evenly arranged on the surface of the fixing seat 64, and four groups of assembly plates 67 are evenly fixed on the top of the flow equalizing tube 66. At the same time, the assembly plates 67 are adapted to the size of the assembly grooves 63, and the assembly plates 67 are clamped inside the assembly grooves 63 and fixed by bolts.

[0027] As a preferred implementation, the distance between two adjacent groups of flow balancing tubes 661 is consistent, and the length of the flow balancing tube 661 is greater than the thickness of the bottom plate of the flow balancing tube 66 .

[0028] The airflow impacts the interior of the flow equalizing tube 66. As the internal air pressure of the flow equalizing tube 66 increases, the airflow overflows from a large number of groups of flow equalizing tubes 661, and a large amount of gas can be evenly distributed, so that the dust-containing gas entering the dust collector body 1 can be evenly distributed.

[0029] Uniform airflow distribution also helps to improve the separation efficiency of the dust collector, because a more stable and uniform airflow can separate dust particles more effectively under the action of centrifugal force, reducing the re-mixing of dust particles into the airflow due to unstable airflow, thereby indirectly reducing the overall operating resistance of the dust collector.
