[0031] Example 1

[0032] Please refer to Figure 1 The present embodiment provides a horn cyclone separator 100, which includes a separator body 110, and the separator body 110 is used to place a separation component for separation and provide necessary space for separation. The structure of the separator body 110 can adopt the structure of a conventional separator body 110 in the prior art, and the present embodiment lists one of them. Specifically, the separator body 110 includes an air inlet pipe 111, a connector 112, a barrel 113, a cone 114 and a dust outlet pipe 115 connected in sequence.

[0033] Further, see Figure 2 The horn separator includes a spiral component 120 for converting the gas in the intake pipe 111 into spiral gas, and the spiral component 120 is arranged in the separator body 110; specifically, in this embodiment, the spiral component 120 is connected to the intake pipe 111. The spiral gas refers to the gas forming a vortex motion rather than a linear motion.

[0034] Furthermore, the spiral assembly 120 includes a plurality of first spiral components 121, which are arranged in the intake pipe 111 along the intake direction of the intake pipe 111 and are all connected to the inner wall of the intake pipe 111. Then, the gas entering the intake pipe 111 acts on the plurality of first spiral components 121, thereby converting the gas into spiral gas.

[0035] Specifically, the first spiral member 121 includes a plurality of spiral blades 1212, and the plurality of spiral blades 1212 are all arranged in the air intake pipe 111, and are arranged in a ring shape in the air intake pipe 111 along the circumferential direction of the air intake pipe 111. Then, when the gas enters the air intake pipe 111, the spiral blades 1212 act on the gas to form a vortex motion of the gas, and then the gas initially has a certain centrifugal force, which is convenient for the subsequent separation of particles or other impurities in the gas.

[0036] Furthermore, the trumpet cyclone separator 100 also includes a cone cap assembly 130 for performing a first cyclonic separation on the spiral gas. The cone cap assembly 130 is disposed in the separator body 110. One end of the cone cap assembly 130 is connected to the separator body 110. The cone cap assembly 130 is overall in an inverted funnel shape to facilitate further centrifugal separation of the gas.

[0037] Specifically, the cone cap assembly 130 includes an upper cone cap 131 and a lower cone cap 132. The upper cone cap 131 and the lower cone cap 132 are both arranged in the separator body 110. The upper cone cap 131 is connected to the separator body 110, that is, it is connected to an end of the connecting piece 112 of this embodiment that is relatively far away from the air inlet pipe 111. The inner wall of the upper cone cap 131 and the outer wall of the lower cone cap 132 are arranged relatively to each other, that is, the upper cone cap 131 is sleeved on the outside of the lower cone cap 132 and is located above it, and then the two can form a separation channel for the centrifugal separation of the spiral gas, that is, the spiral gas formed after passing through the spiral assembly 120 passes between the upper cone cap 131 and the lower cone cap 132, and the spiral gas has centrifugal force, and the pollutant particles move to the outside of the gas. When the pollutant particles hit the inner wall of the upper cone cap 131, the rotation speed of the pollutant particles is reduced due to friction. At the same time, the pollutant particles Driven by the gas, the polluted particles will move toward the outer edge of the upper cone cap, while the gas containing fewer or no polluted particles will move toward the outer edge of the lower cone cap 132. That is, the polluted particles are enriched and preliminarily stratified between the upper cone cap 131 and the lower cone cap 132, and then the gas flows out of the separation channel between the upper cone cap 131 and the lower cone cap 132 and enters the separator body 110. The airflow will act on the cone 114 of the separator body 110 and continue to rotate. The enriched polluted particles fall along the cone 114 of the separator body 110 under the action of inertia.

[0038] At the same time, the upper cone cap 131 and the lower cone cap 132 are both in an inverted funnel shape, which further ensures the separation effect.

[0039] Furthermore, the horn cyclone separator 100 also includes a cyclone separation component 140 for performing a second cyclone separation on the spiral gas. The cyclone separation component 140 is arranged in the separator body 110. The other end of the cone cap component 130 is connected to the cyclone separation component 140, that is, the lower cone cap 132 is connected to the cyclone separation component 140. Specifically, the lower cone cap 132 is connected to the end of the outlet pipe 141 of the cyclone separation component 140, so that the gas passing through the spiral component 120 The gas enters the cone cap assembly 130 for the first separation, and at the same time, the air outlet of the cone cap assembly 130 is connected to the air inlet of the cyclone separation assembly 140. Specifically, in this embodiment, the height of the air inlet of the cyclone separation assembly 140 is lower than the height of the connection between the lower cone cap 132 and the cyclone separation assembly 140, that is, the air inlet of the cyclone separation assembly 140 is below the lower cone cap 132, so that the gas passing through the cone cap assembly 130 enters the cyclone separation assembly 140 for secondary separation.

[0040] Furthermore, the outlet pipe 141 of the cyclone separation assembly 140 in this embodiment is also the outlet pipe 141 of the trumpet cyclone separator 100, and the inlet pipe 111 is sleeved outside the outlet pipe 141, so that the gas that has been separated for the second time by the cyclone separation assembly 140 flows out of the trumpet cyclone separator 100. In this embodiment, the spiral assembly 120 is connected to the inlet pipe 111, but is not in contact with or connected to the outlet pipe 141, so as to improve the circulation of the gas.

[0041] It should be noted that the cyclone separation component 140 can adopt a first-stage cyclone separator in the prior art, such as a vertical cyclone separator. The cyclone separation component 140 is an existing first-stage cyclone separator, so it can be directly fixed to the ground without being connected to the separator body 110. Of course, in order to improve stability, it can be fixedly connected to the inner wall of the separator body 110, but it affects the flow of gas. At the same time, since the volume of the cyclone separator is relatively small compared to the intake air, the rotation speed inside the cyclone separator is higher, so that smaller particles in the gas can be separated, and smaller particles can be separated, thereby achieving the removal of particles of different particle sizes.

[0042] At the same time, the cyclone separation component 140 may have more than one air inlet, and the air inlets are all tangent to the body of the cyclone separation component 140, so that the airflow entering the cyclone separation component 140 is a spiral airflow.

[0043] Furthermore, the horn cyclone separator 100 includes a dust collecting part 150, which is connected to the dust outlet pipe 115 of the separator body 110, and the dust collecting part 150 is connected to the dust outlet pipe 115 of the cyclone separation assembly 140, so as to collect the dust and other pollutant particles in the cyclone separator assembly and the pollutant particles passing through the cone cap assembly 130.

[0044] The working process of the horn cyclone separator 100 provided in this embodiment is:

[0045] An exhaust fan is connected to the end of the air outlet pipe 141 to extract air, so that negative pressure is generated inside the horn cyclone separator 100, and the dust-containing gas enters the horn cyclone separator 100 from the air inlet pipe 111, and then the dust-containing gas acts on the spiral component 120, so that the dust-containing gas forms a vortex motion, and then the dust-containing gas enters the separation channel between the upper cone cap 131 and the lower cone cap 132. Under the action of centrifugal force, some pollutant particles move to the outside of the air flow. When the pollutant particles hit the inner wall of the upper cone cap, the rotation speed is reduced due to friction, and the pollutant particles will move toward the outer edge of the upper cone cap driven by the air flow. When the gas flows out of the separation channel between the upper cone cap and the lower cone cap, it will hit the inner wall of the separator body 110. At the same time, it continues to rotate, and the separated pollutant particles move downward along the cone 114 of the separator body 110 under the action of inertia and fall into the dust collecting bin. The separated gas turns at the cone 114, moves upward, enters from the air inlet of the cyclone separation assembly 140, continues to rotate and separate inside the cyclone separation assembly 140, and the separated pollutant particles fall into the dust collecting bin connected to the dust outlet pipe 115 of the cyclone separation assembly 140, and the purified gas is discharged from the outlet pipe 141 of the cyclone separation assembly 140.

[0046] Example 2

[0047] See also Figure 3 The structure of the horn cyclone separator (not shown) provided in this embodiment is basically the same as the structure of the horn cyclone separator 100 provided in Example 1, except that the connection positions of the upper cone cap 131 and the spiral assembly 120 are different.

[0048] Specifically, the upper cone cap 131 is connected to the end portion where the air inlet pipe 111 and the connecting member 112 are connected, and the spiral assembly 120 includes a plurality of second spiral members 122, which are arranged outside the air outlet pipe 141 along the air outlet direction of the air outlet pipe 141, and are all connected to the outer wall of the air outlet pipe 141. It should be noted that the second spiral member 122 has the same structure as the first spiral member 121 provided in Example 1. The second spiral member 122 includes a plurality of spiral sheets, which are arranged outside the air outlet pipe 141 in an annular manner around the outer circumference of the air outlet pipe 141, and are connected to the air outlet pipe 141, so that the gas can form a vortex motion.

[0049] Example 3

[0050] See also Figure 4 The structure of the horn cyclone separator (not shown) provided in this embodiment is basically the same as the structure of the horn cyclone separator 100 provided in Example 1, except that the connection position of the spiral component 120 is different.

[0051] Specifically, the spiral assembly 120 includes at least one third spiral component 123 , each of the third spiral components 123 is disposed between the upper cone cap 131 and the lower cone cap 132 , and each of the third spiral components 123 is connected to the lower cone cap 132 .

[0052] It should be noted that the third spiral member 123 of this embodiment has the same structure as the first spiral member 121 provided in Embodiment 1. In addition to being connected to the lower cone cap 132 , the third spiral member 123 can also be connected to the upper cone cap 131 .

[0053] Meanwhile, in addition to the structures provided in embodiments 1-3 of the present invention, the spiral assembly 120 may also adopt other structures. For example, the two ends of a bearing may be welded to the air inlet pipe 111 and the air outlet pipe 141 respectively, and a spiral blade may be installed on the bearing, and then the spiral blade may convert the gas in the air inlet pipe 111 into spiral gas. The number of spiral blades on the bearing may be multiple, and the number of bearings may also be multiple, and the bearing may also be welded to the upper cone cap 131 and the lower cone cap 132.

[0054] Example 4

[0055] See also Figure 5 The present embodiment provides a horn cyclone separator 200 having a structure that is substantially the same as the horn cyclone separator 100 provided in Embodiment 1, with the difference that the horn cyclone separator 200 of the present embodiment has a plurality of cyclone separation components 140, and the cyclone separation components 140 can still adopt the primary cyclone separator in the prior art.

[0056] Meanwhile, the air outlet pipe 141 of the cyclone separation assembly 140 is not the air outlet pipe 141 of the trumpet cyclone separator 100, but the air inlet pipe 111 is still sleeved outside the air outlet pipe 141 of the trumpet cyclone separator 100, and the air outlet of each cyclone separation assembly 140 is connected to the air outlet pipe 141 of the trumpet cyclone separator 100. Meanwhile, each cyclone separation assembly 140 is located in the conical cavity formed by the lower cone cap 132, that is, below the lower cone cap 132.

[0057] In summary, the embodiment of the present invention provides a horn cyclone separator, which converts the gas without spiral properties into spiral gas by setting a spiral component, so that it initially has a certain centrifugal force. A cone cap component is set so that the spiral gas further generates centrifugal force in the cone cap component, and the gas is separated for the first time, and then the cyclone separation component is used to separate the gas for the second time, and then multiple separations are achieved, and different separation structures are used to separate particles of different particle sizes. At the same time, the horn cyclone separator has good separation effect, simple structure, and can be applied industrially.

[0058] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the present invention should be included in the protection scope of the present invention.
