Description
Technical Field

Background
Cyclone separators are a device for gas-solid separation or gas-liquid separation. The cyclone separator works in such a way that dust-carrying airflow is introduced into a cylindrical separation cavity from a tangential direction to cause rotation of the airflow, and solid or liquid is utilized to have a large centrifugal force in the rotation process, so that solid particles or liquid drops are thrown to the side wall of the cylindrical separator, and the solid or liquid is separated from the gas. In order to make the cyclone airflow more stable and controllable, and at the same time ensure that the incoming airflow is not mixed with the outgoing airflow, a special spiral drainage channel is usually arranged in the cyclone separator for guiding the incoming airflow and isolating the incoming airflow from the outgoing airflow.

The known wet and dry separators generally comprise a cyclone, an inlet duct and an outlet duct, and a filter for filtering dust in a vacuum cleaner. When the cyclone dust collector works, air flow with sewage and dust particles enters the cyclone barrel from the air inlet channel to rotate, the sewage and dust particles are thrown to the side wall of the cyclone barrel in the rotating process, then deposited to the bottom of the dust cup under the action of gravity, clean air flows out of the cyclone barrel through the air outlet channel, and a filter is further arranged at the air outlet channel in the cyclone barrel in order to prevent fine dust mixed in the air flow from flowing out of the cyclone barrel in the dust collector.
However, in the actual use process of the dry-wet dual-purpose cyclone separator, as the separated sewage and dirt are gradually increased, the sewage is closer to the filter, and when the accumulated sewage in the barrel reaches a certain degree, the sewage overflows and passes through the filter to enter the air outlet channel, and finally is discharged out of the separator along with air flow, so that the sewage leaks.

The technical scheme provided by the invention has the following advantages:
1. The cyclone separation assembly comprises a dirt collecting device, a first drainage channel, an air outlet part and a floating component, wherein the dirt collecting device is barrel-shaped and is provided with a barrel-shaped separation cavity, and an air inlet is formed in the dirt collecting device; the first drainage channel is arranged in the dirt collecting device, is communicated with the air inlet and is provided with a spiral channel which is suitable for enabling the air in the air inlet part to rotate after entering the separation cavity; the air outlet part is communicated with the separation cavity and is suitable for enabling clean air after rotary separation to flow out of the separation cavity; the floating component is arranged in the separation cavity and is suitable for floating upwards and sealing the air outlet part when being subjected to buoyancy. The working process of the components is as follows: the dust-carrying airflow enters the separating cavity of the dirt collecting device from the air inlet part, the dust-carrying airflow rotates under the guidance of the first guide channel, sewage and particles in the airflow are thrown to the side wall of the separating cavity, finally the sewage and the particles are deposited to the bottom of the separating cavity under the action of gravity, and the airflow from which the sewage and the particles are separated is discharged out of the separating assembly through the air outlet part. In the whole separation process, along with accumulation of sewage at the bottom of the separation cavity, the sewage can finally touch the floating component and float the floating component, and the floating component after floating further seals up the air outlet part, so that the communication between the air outlet part and the separation cavity is cut off, after the circulation of gas is blocked, the whole cyclone separation process is stopped, and the sewage can not enter the separation cavity again, so that the sewage leakage problem caused by overflow of the sewage is avoided.
2. The cyclone separation assembly provided by the invention further comprises a lining barrel, wherein the lining barrel is arranged in the separation cavity, and a spiral air deflector is arranged on the outer wall of the lining barrel in a surrounding manner; the first drainage channel is formed by splicing the air deflector with the outer wall of the lining barrel and the inner wall of the separation cavity together. By designing the first drain in the above-described manner, on the one hand, the first drain can be programmed in an open manner after the liner is removed from the separation chamber, so that more convenient cleaning can be performed; on the other hand, through introducing the lining barrel structure, the injection molding process difficulty of the single assembly can be reduced by increasing the number of parts of the assembly, the molding quality of the single assembly is ensured, and the overall quality of the assembly is improved.
3. The cyclone separation assembly provided by the invention further comprises a first filtering structure which is arranged on the side wall of the lining barrel, communicated with the air outlet part and suitable for filtering air flow entering the air outlet part. Particles and sewage in the dust-carrying airflow subjected to cyclone separation are thrown to the side wall of the separation cavity to be separated, and part of particles still exist in the airflow and cannot be thrown out completely, so that the particles in the airflows can be further filtered by the aid of the first filtering structure, and dust particles in the discharged airflows are avoided.

In the process, due to the existence of the second guide channel, the flowing air flow can not be mixed with the cyclone air flow, so that the air flow stability of the cyclone air flow during rotation can be ensured, and meanwhile, the flowing air flow can not bring dust and dirt out of the cyclone air flow. Therefore, the structure can improve the working stability of the cyclone separation assembly and the dust-gas separation effect.

This enables the integration of the function of the first filtering structure on the side wall of the liner, on the one hand avoiding the complexity of the structure resulting from the separate installation of the filtering parts; on the other hand, the structure can enable the first filtering structure to extend along the second drainage channel, and gas can pass through the first filtering structure from the tangential direction of the drainage channel in the process of flowing along the second drainage channel, so that the possibility of gas flow disturbance is reduced.
7. In the cyclone separation assembly provided by the invention, the second filtering structure is arranged at the communication part of the second diversion channel and the separation cavity, and the second filtering structure is suitable for filtering the airflow entering the second diversion channel from the separation cavity.

In the cyclone separation assembly provided by the invention, the floating member is cylindrical, the outer wall of the cylindrical floating member is slidably attached to the inner wall of the lining cylinder, and the floating member is suitable for sealing the filtering holes arranged on the side wall of the lining cylinder when floating. After the floating member is designed into the form, the floating member is matched with the inner wall of the cylindrical lining barrel, and can be pressed on the inner wall of the lining barrel under the action of negative pressure at the air outlet when the lining barrel floats, so that the blocking effect of the floating member on the first filtering structure is ensured. On the other hand, the cylindrical floating component can occupy the space in the separation cavity as little as possible, so that sufficient space is provided for cyclone airflow, and the cyclone separation effect is improved.
9. In the cyclone separating assembly provided by the invention, a plurality of guide pairs are arranged between the outer wall of the floating member and the inner wall of the lining barrel, and the guide pairs are suitable for limiting the floating member to move only along the axial direction of the lining barrel.

In addition, the technical features of the different embodiments of the present invention described below may be combined with each other as long as they do not collide with each other.
Example 1:
As shown in fig. 1, an embodiment 1 of the present invention is a euro-guan cyclone separation assembly, which is used for being installed on a dust collector to separate dust from air and separate liquid from air.
The embodiment comprises a dirt collecting device 1, a first drainage channel 2, an air outlet part 3 and a floating member 5. As shown in fig. 6, the dirt collecting device 1 is barrel-shaped and is provided with a barrel-shaped separation cavity 101, and an air inlet 102 is formed in the dirt collecting device 1; the first diversion channel 2 is arranged in the sewage collecting device 1, is communicated with the air inlet 102 and is provided with a spiral channel which is suitable for enabling the air in the air inlet part to rotate after entering the separation cavity 101; the air outlet part 3 is communicated with the separation cavity 101 and is suitable for enabling clean air after rotary separation to flow out of the separation cavity 101; mounted in the separation chamber 101, said floating member 5 is adapted to float upwards and to seal off the air outlet 3 when subjected to buoyancy.
The dirt collecting device 1 is used for containing dirt and sewage, and the separating chamber 101 in the dirt collecting device is used for generating whirlwind, so that the best mode is a barrel shape, because the dirt-bearing airflow is more beneficial to forming the whirlwind shape, but the dirt collecting device 1 can also be designed into an oblong shape, an elliptic shape, or even a barrel with a different cross section.
The working process of the components is as follows: the dust-carrying air flow enters the separating cavity 101 of the dirt collecting device 1 from the air inlet part, and rotates under the guidance of the first guide channel 2, so that sewage and particles in the air flow are thrown to the side wall of the separating cavity 101, and finally the sewage and the particles are deposited to the bottom of the separating cavity 101 under the action of gravity, and the air flow from which the sewage and the particles are separated is discharged out of the separating assembly through the air outlet part 3. In the whole separation process, along with accumulation of sewage at the bottom of the separation cavity 101, the sewage finally touches the floating member 5 and floats the floating member 5, the floating member 5 further seals the air outlet part 3, thereby cutting off communication between the air outlet part 3 and the separation cavity 101, stopping the whole cyclone separation process after blocking gas circulation, and the sewage can not enter the separation cavity 101 again, so that the sewage leakage problem caused by overflow of the sewage is avoided.
As shown in fig. 2 and 3, a schematic structural diagram of the liner 6 in this embodiment is shown, the liner 6 is installed in the separation chamber 101, and a spiral air deflector 61 is circumferentially disposed on the outer wall of the liner 6; after the liner 6 is installed in the separation chamber 101, the first guide channel 2 is formed by jointly splicing the air deflector 61 with the outer wall of the liner 6 and the inner wall of the separation chamber 101.
By designing the first flow guiding channel 2 in the above-described form, on the one hand, the first flow guiding channel 2 can be programmed to be open after the liner 6 is detached from the separation chamber 101, so that more convenient cleaning can be performed; on the other hand, by introducing the structure of the lining cylinder 6, the injection molding process difficulty of the single assembly can be reduced by increasing the number of parts of the assembly, the molding quality of the single assembly is ensured, and the overall quality of the assembly is improved.
In order to improve the separation performance of the cyclone separation assembly, the embodiment further comprises a first filtering structure 4, which is arranged on the side wall of the lining cylinder 6, is communicated with the air outlet part 3, and is suitable for filtering the air flow entering the air outlet part 3. Particles and sewage in the cyclone dust-carrying airflow are thrown to the side wall of the separation cavity 101 to complete separation, and part of particles still exist in the airflow and cannot be thrown out completely, so that the particles in the airflow can be further filtered by the first filtering structure 4, and dust particles in the discharged airflow are avoided. Therefore, the dust-gas separation effect of the cyclone separation assembly can be improved by the structure.
As an improved embodiment of the cyclone separation assembly, the cyclone separation assembly further comprises a second guiding channel 7, wherein one end of the second guiding channel 7 is communicated with the separation cavity 101, and the other end of the second guiding channel extends to the surface of the first filtering structure 4 and is suitable for guiding the airflow in the separation cavity 101 to enter the first filtering structure 4. The gas coming out from the first diversion channel 2 forms cyclone gas flow in the separation cavity 101, and after the separation process is completed, the gas flow enters the second diversion channel 7 and passes through the first filtering structure 4 under the guidance of the second diversion channel 7. In the above process, the second flow guiding channel 7 does not mix the flowing air with the cyclone air, so that the air stability of the cyclone air during rotation can be ensured, and the flowing air can not carry dust in the cyclone air. Therefore, the structure can improve the working stability of the cyclone separation assembly and the dust-gas separation effect.
Specifically, the second flow guiding channel 7 is formed by jointly splicing the air guiding plate 61 with the outer wall of the liner 6 and the inner wall of the separation chamber 101. Similar to the effect of the first drainage channel 2, after the second drainage channel 7 is designed into the form, on one hand, the first drainage channel 2 can be changed into a form with one side opened after being detached, so that the first drainage channel is convenient to clean; on the other hand, the second guide channel 7 can be integrated on the lining cylinder 6, so that the function integration of the lining cylinder 6 is improved, the number of parts is reduced, and the complexity in assembly is reduced.
As a specific embodiment of the first filtering structure 4, the first filtering structure 4 is a plurality of filtering holes 8 formed on the sidewall of the liner 6 which is spliced into the second guide channel 7.
