[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0029] See also Figures 1 to 5 , the utility model provides a technical solution:
[0030] A spiral water mist dust collector comprises: a body 1, an explosion-proof fan 2 is installed on the top of the body 1, and a plurality of raised cups 3 are arranged on the bottom of the body 1; a spray device 4, the spray device 4 is arranged in the upper part of the body 1, and is used to combine dust in the air with water mist; a cyclone processing device 5, the cyclone processing device 5 is arranged in the middle part of the body 1, and is used to separate dust in the air; the water supply device 6 is arranged in the bottom of the body 1, and is used to supply water to the spray device 4.
[0031] Specifically, the spray device 4 includes an upper spray pipeline 7, a lower spray pipeline 8, a dust isolation layer 9 and a water mist isolation layer 10. The upper spray pipeline 7 and the lower spray pipeline 8 are respectively installed in the inner cavity of the body 1. The surfaces of the upper spray pipeline 7 and the lower spray pipeline 8 on one side are provided with a dust isolation layer 9 to form a primary spray layer 11. The water mist isolation layer 10 on the other side is arranged on the surface of the upper spray pipeline 7, and the surface of the lower spray pipeline 8 is provided with a dust isolation layer 9, which together constitute a secondary spray layer 12. An S-shaped air duct spray pipeline 13 is formed in the middle. The dust airflow entering the body 1 is sprayed three times by the primary spray layer 11, the secondary spray layer 12 and the air duct spray pipeline 13, and then filtered multiple times by the water mist isolation layer 10 and the dust isolation layer 9, so that the dust removal efficiency is greatly improved. The dust isolation layer 9 and the water mist isolation layer 10 are both in the shape of drawers and are detachably connected to the machine body 1. In actual use, they need to be taken out and rinsed with water every 7 to 10 days and then put back, which can extend their service life.
[0032] Specifically, the cyclone treatment device 5 includes a primary cyclone barrel 14, a secondary cyclone barrel 15, a primary sedimentation tank 16 and a secondary sedimentation tank 17. The primary cyclone barrel 14 is arranged on one side of the inner wall of the body 1, the top of the primary cyclone barrel 14 is fixedly connected to the primary spray layer 11, and the bottom is fixedly connected to the primary sedimentation tank 16. The secondary cyclone barrel 15 is arranged on the other side of the inner wall of the body 1, the top of the secondary cyclone barrel 15 is fixedly connected to the secondary spray layer 12, and the bottom is fixedly connected to the secondary sedimentation tank 17. The primary cyclone barrel 14 and the secondary cyclone barrel 15 are both installed with a swirl impeller 18 inside. The cyclone stirring generated by the operation of the swirl impeller 18 is used to fully merge the dust and water. The centrifugal force generated during the strong rotation process throws the dust particles with a density much greater than that of the gas to the wall of the device. Once the dust particles contact the wall of the device, the coarse dust and impurities that lose their inertia force fall into the sedimentation tank along the wall along the cyclone and their own gravity, and are not easy to block the air outlet of the dust collector.
[0033] Specifically, the water storage device 6 includes a primary large water storage tank 19, a secondary water tank 20, an explosion-proof submerged pump 21 and a spray pipe 22. The primary large water storage tank 19 is located at the bottom of the body 1. One side of the primary large water storage tank 19 is connected to the secondary water tank 20 through a filter slag retaining net 23. An explosion-proof submerged pump 21 is installed in the secondary water tank 20. The outlet end of the explosion-proof submerged pump 21 is fixedly connected to the water inlet of the spray pipe 22. The outlet of the spray pipe 22 is connected to the upper spray pipeline 7 and The lower spray pipeline 8 provides storage circulating water for the entire dust collector by setting a large primary water storage tank 19 at the lower part of the body 1. The secondary water tank 20 is set on one side of the large primary water storage tank 19 to adjust the water level and ensure that the nozzle obtains a stable water supply and maintains a constant water pressure. The explosion-proof submersible pump 21 is set in the secondary water tank 20 to provide circulating water for the upper spray pipeline. On one side of the filter slag screen 23, there is a "7"-shaped water tank partition that separates the large primary water storage tank 19 and the secondary water tank 20.
[0034] Specifically, an external air inlet 24 is installed on the side of the first-stage cyclone barrel 14, and an observation window 25 is provided on the other side. The second-stage cyclone barrel 15 is fixedly connected to the air duct sealing plate 26, and the swirl impeller 18 needs the air inlet 24 to provide air when working.
[0035] Specifically, an inspection door 28 is hinged on the surface of the body 1 through a hinge 27, and a handle 29 is provided on the inspection door 28. During daily maintenance, the internal components of the body 1 can be inspected and cleaned by opening the inspection door 28 to ensure the good operation of the equipment.
[0036] Specifically, a plurality of silt removal ball valves 30 are installed at the bottom of the first large water storage tank 19 and the second water flow tank 20, and an overflow port 31 and a stainless steel float 32 are provided at the upper portion of the second water flow tank 20. The overflow port 31 and the stainless steel float 32 can be used to control the water level to ensure that the water level is not too high or too low, so as to ensure the normal operation of the dust collector and prevent water from entering other equipment to protect the dust collector from damage. The silt removal ball valve 30 can timely discharge the silt deposited at the bottom of the first large water storage tank 19 and the second water flow tank 20 to prevent equipment clogging, thereby extending the service life of the dust collector.
[0037] Specifically, the spray nozzles of the upper spray pipeline 7 and the lower spray pipeline 8 are spiral spray nozzles 33, which disperse water into fine particles and perform uniform atomization through rapid rotation. The spray particle size is fine and uniform, and it is not easy to clog the nozzle.
[0038] The working principle of this embodiment is as follows: when in use, the dust airflow enters the primary cyclone 14 through the external air inlet 24, and generates cyclonic stirring when passing through the swirl impeller 18 to fully blend the dust and water. The heavier coarse dust particles and impurities flow down along the cyclone wall with the water to the primary sedimentation tank 16 for precipitation. The water flow is sucked into the spray layer through the explosion-proof submersible pump 21 from the secondary water trough 20, and then sprayed out through the spiral spray nozzles 33 at various locations. The dust airflow enters the primary spray layer 11, is sprayed with water mist twice up and down and purified again, and then enters the air duct spray pipeline 13. It is again purified by the spray water mist of the upper and lower spray layers and then enters the secondary cyclone 15. The slightly coarse particles in the dust airflow are fully stirred by the swirling airflow and flow along the wall of the secondary cyclone 15 and the water to the secondary sedimentation tank 17 (at this time, the removal amount of coarse particles in the dust airflow reaches more than 95%). Then the dust gas enters the secondary spray layer 12, and is sprayed and purified by the water mist of the upper and lower spray layers again. After passing through the final water mist isolation layer 10, the airflow without water mist and dust is discharged from the air outlet of the explosion-proof fan 2, and finally the purpose of thorough purification is achieved.
