[0017] Compared with the prior art, the beneficial effects of the present invention are as follows:

After passing through the impeller, under the rotation of the water distribution device and the impeller, the airflow and water curtain mix and enter the ventilation duct. Under the action of the blades, the mixed water and air are thrown onto the inner wall of the mounting housing. Some water falls from the second water passage, grabbing some dust and falling down. Then, it enters the water collection tank through the water collection tank. Then, the airflow passes through multiple sets of water curtains formed by the water curtain forming device, grabbing dust multiple times. Then, the airflow with water passes through the dehydration tank, and the water falls from the first water passage and continues to enter the water collection tank through the water collection tank. The airflow that has been washed by water is discharged from the air outlet, completing the dust removal and cleaning process of the air.

[0019] The process of forming a water curtain is as follows: Water from an external water source enters the inner cavity of the motor protective shell through the inlet pipe, filling the inner cavity with water. Then, the water enters the water passage through the outlet trough and then the water storage cavity. It is then sprayed out from the spray trough. Under the action of high-speed rotation, multiple sets of water curtains are formed. The water that falls onto the inner wall enters the water collection trough through the collection trough and then enters the water distribution device through the outlet pipe. Part of the water in the outlet pipe flows out from the outer wall of the conical sleeve to form a water curtain, and the other part enters the water distribution seat and passes through the water distribution holes to form a water curtain, thus completing the water circulation.

[0020] This invention has a simple structure, effectively captures dust from the air, greatly improves the dust removal effect, and the water used to capture dust can also cool the motor, preventing it from overheating and burning out after prolonged operation, thus extending the service life of the equipment.

[0027] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0028] like Figures 1 to 6 An air dust removal and cleaning device is shown, comprising: a mounting housing 1, an impeller 2, a motor 3, a motor protective housing 4, and a dehydration tank 5; the motor 3 is a dual-output shaft motor; the mounting housing 1 is a horizontally arranged cylindrical housing structure, with an air inlet 1-1 in the middle of the left side wall and an air outlet 1-2 in the middle of the right side wall; the motor 3 is a dual-output shaft motor, with the left output shaft used to drive the rotation of the impeller 2 and the right output shaft used to drive the water curtain forming device 7.

[0029] The impeller 2 and the motor 3 are horizontally and coaxially arranged in the inner cavity of the mounting housing 1 from left to right. The motor protective housing 4 is coaxially arranged outside the motor 3. The space between the motor protective housing 4 and the mounting housing 1 is a ventilation channel 1-3. Several sets of blades 1-3-1 are arranged in the ventilation channel 1-3. The impeller 2 throws the airflow to the outside, and the airflow enters the ventilation channel 1-3. Under the action of the blades 1-3-1, the airflow is thrown onto the inner wall of the mounting housing 1 and leaves the ventilation channel 1-3 from the right side.

[0030] A flange mounting hole 4-1 is provided in the middle of the left side wall of the motor protective housing 4, and a water passage hole 4-2 is provided in the middle of the right side wall of the motor protective housing 4; the left end flange of the motor 3 is fixed in the flange mounting hole 4-1, the left end of the impeller 2 is provided in the air inlet hole 1-1, the right end of the impeller 2 is fixed on the left end output shaft of the motor 3, and a water passage shaft 6 is coaxially fixed on the right end output shaft of the motor 3, and the right end of the water passage shaft 6 extends out of the right side wall of the motor protective housing 4, and a water curtain forming device 7 is provided on the right end of the water passage shaft 6; the dehydration tank 5 is horizontally arranged to the right of the water curtain forming device 7, and the right outlet of the dehydration tank is opposite to the air outlet hole 1-2. The motor protective shell 4 serves to fix the motor 3 in place, and the water inside also cools the motor 3. The flange at the front end of the motor 3 is fixed to the flange mounting hole 4-1, and the water-passing shaft 6 in the water-passing hole 4-2 further enhances the stability of the rear end of the motor 3. The dehydration tank 5 is designed to throw the water in the airflow into the mounting shell 1 to prevent the water from being discharged with the airflow. The water curtain forming device 7 is used to form a water curtain to capture dust in the airflow.

[0031] Furthermore, the dehydration tank 5 is a horizontally arranged conical cylindrical structure, wider on the left and narrower on the right. The left end of the dehydration tank 5 is fixedly connected to the inner wall of the mounting housing 1. The side of the dehydration tank 5 is an inwardly curved surface, and several sets of first water passage grooves 5-1 are evenly distributed on the side of the dehydration tank 5. The conical cylindrical structure of the dehydration tank 5 facilitates water drop, with water falling from the first water passage grooves 5-1 into the mounting housing 1.

[0032] Furthermore, the inner diameter of the right end of the dehydration tank 5 is larger than the inner diameter of the air outlet 1-2. This prevents the water that has been shaken out from being discharged through the air outlet 1-2.

[0033] Furthermore, the blade 1-3-1 is an airfoil-shaped blade, and a second water channel 1-3-2 is provided on the blade 1-3-1. The second water channel 1-3-2 is used for the initial drop of water in the airflow, completing the collection after the initial capture of dust.

[0034] Furthermore, sealing rings are provided between the flange mounting hole 4-1 and the left end flange of the motor 3, and between the water inlet hole 4-2 and the water inlet shaft 6. The sealing rings ensure that water in the motor protective housing 4 overflows from both sides.

[0035] Furthermore, the water curtain forming device 7 includes a cylindrical rotating seat 7-1, a water storage cavity 7-1-1 is provided inside the rotating seat 7-1, a water passage hole 7-1-2 is provided on the left side wall of the water storage cavity 7-1-1, a water passage groove 6-1 is coaxially provided inside the water passage shaft 6, and a water outlet groove 6-2 is provided on the side wall of the water passage shaft 6 located inside the motor protective shell 4, which connects the water passage groove 6-1 and the inner cavity of the motor protective shell 4. The right end of the water passage shaft 6 is fixed in the water passage hole 7-1-2 by a fixing device 7-2, and the water passage groove 6-1 is connected to the water storage cavity 7-1-1.

[0036] The outer circumferential wall of the water storage chamber 7-1-1 is provided with several sets of water spray channels 7-1-3 arranged radially, and the sets of water spray channels 7-1-3 are not located on the same circumference. The rotating seat 7-1 rotates with the water-passing shaft 6. The water in the motor protective shell 4 enters the water-passing channel 6-1 after passing through the water outlet channel 6-2 on the water-passing shaft 6, and then enters the water storage chamber 7-1-1. It is then sprayed out from the water spray channels 7-1-3. Under the action of rotation, multiple sets of water curtains are formed, which complete the multiple capture of dust in the airflow and improve the dust removal efficiency.

[0037] Furthermore, the fixing device 7-2 includes an annular fixing seat 7-2-1, which is coaxially fixed on the left side wall of the rotating seat 7-1. The inner diameter of the annular fixing seat 7-2-1 is the same as the inner diameter of the water passage hole 7-1-2. The annular fixing seat 7-2-1 is fixedly connected to the water passage shaft 6 by a set screw 7-2-2. Using a set screw 7-2-2 for fixing is preferable because threaded fixing is prone to falling off during rotation, while welding fixing is difficult to install and disassemble.

[0038] Furthermore, the air dust removal and cleaning device also includes a water source transportation and recycling device 9. The water source transportation and recycling device 9 includes an inlet pipe 9-1, an outlet pipe 9-2, and a water collection tank 9-3. One end of the inlet pipe 9-1 is connected to an external water source, and the other end of the inlet pipe 9-1 passes through the mounting housing 1 and the motor protective housing 4 and is located in the inner cavity of the motor protective housing 4. The bottom of the mounting housing 1 is provided with a water collection tank 1-4 in the left and right direction. The water collection tank 9-3 is fixedly located on the lower side of the mounting housing 1 and the water collection tank 9-3 is connected to the inner cavity of the mounting housing 1 through the water collection tank 1-4.

[0039] A water distribution device 10 is installed at the center of the impeller 2. One end of the water outlet pipe 9-2 is connected to the bottom wall of the water collection tank 9-3, and the other end is located at the water distribution device 10. The water distribution device 10 evenly sprays the water in the water outlet pipe 9-2. A pump body is installed on the water outlet pipe 9-2, which facilitates the return of water from the water collection tank 9-3 to the device for reuse.

[0040] Furthermore, the water distribution device 10 includes a horizontally arranged cylindrical water distribution seat 10-1, which is coaxially fixed at the center of the impeller 2. The water distribution seat 10-1 is provided with a water distribution cavity 10-1-1. Two sets of opposing water distribution holes 10-1-2 are provided on the outer circumferential wall of the water distribution cavity 10-1-1. A horizontally oriented tapered sleeve 10-1-3, which is smaller on the left and larger on the right, is provided in the middle of the left side wall of the water distribution cavity 10-1-1. The tapered sleeve 10-1-3 communicates with the water distribution cavity 10-1-1. The left end of the tapered sleeve 10-1-3 is located at the end of the water outlet pipe 9-2 near the water distribution device 10, and the outer diameter of the left end of the tapered sleeve 10-1-3 is smaller than the inner diameter of the water outlet pipe 9-2. The water distribution device 10 ensures that the water entering the device comes into uniform contact with the airflow, and through the conical sleeve 10-1-3 and the water distribution hole 10-1-2, a water curtain is formed, which fully enables the airflow to come into contact with the water and captures dust.

[0041] The working process of this invention: External water source enters the inner cavity of motor protective shell 4 through water inlet pipe 9-1, filling the inner cavity. Water continues to enter, and water enters water passage 6-1 from water storage tank 6-2, and then enters water storage cavity 7-1-1. It is sprayed out from water spray tank 7-1-3. Under the action of rotation, multiple sets of water curtains are formed to complete the multiple capture of dust in the airflow.

[0042] Water enters the water distribution device 10 from the outlet pipe 9-2, forming a water curtain, so that the airflow and water come into uniform contact. Then, the airflow enters the ventilation duct 1-3 under the action of the impeller 2. Some water falls from the second water passage 1-3-2. Then the airflow passes through the water curtain formed by the water curtain forming device 7 to thoroughly capture dust. After passing through the dehydration tank 5, the water falls from the first water passage 5-1, and clean air is discharged from the air outlet 1-2.

[0043] Water that falls into the housing 1 enters the collection tank 9-3 from the bottom water collection tank 1-4, and then enters the water distribution device 10 again through the water outlet pipe 9-2 to continuously capture dust.

[0044] This invention uses water as a medium. Under the action of the impeller, the small droplet particles formed by the water equalization device 10 combine with dust particles in the air. Then, the particles are guided by the blades to generate a spiral motion, and then the dehydration tank 5 performs gas-liquid separation to achieve purification.

[0045] In this invention, water treatment does not require external drive; the water curtain can be formed directly using motor 3. The structure is simple, the operation is convenient, the dust removal effect is good, the motor heat dissipation effect is good, and the service life of the device is improved.
