Description

Technical Field

[0001] The utility model relates to the technical field of fog cannons, in particular to a micro-mist dust suppression fog cannon. Background Art

[0002] The fog cannon is a dust removal wet spray fan. Based on the wind conveying principle, it uses a high-pressure pump and atomizing nozzle to atomize water into fine water mist, and then uses the rotation of the fan to generate airflow to send the atomized water mist to a longer distance. The water mist adheres to the dust in the air while reaching a longer distance, and the dust in the air condenses into clumps, and finally falls to the ground under the action of gravity, thereby achieving the purpose of dust removal. Therefore, the fog cannon, as an environmental protection machine, is suitable for construction sites, coal yards, mines, construction sites and other places where dust is prone to occur.

[0003] However, the existing fog cannons still have some defects during use: although the fog cannons can atomize water into fine water mist through a high-pressure pump and an atomizing nozzle, the atomization effect of the water mist is not good, and it is easy to form larger water droplets, which in turn affects the dust removal efficiency. Utility Model Content

[0004] The utility model provides a micro-mist dust suppression fog cannon to solve the problems raised in the above background technology.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A micro-mist dust suppression fog cannon comprises a barrel body, a fan is arranged in the barrel body, a water supply ring pipe is fixedly connected to the side wall of one end of the barrel body, a water inlet pipe is fixedly connected to the side wall of the water supply ring pipe, a plurality of atomizing nozzles are fixedly connected to the side wall of the water supply ring pipe and arranged in a circular array, an air pump is arranged on the outer side wall of the barrel body, and the air pump is connected to the plurality of atomizing nozzles through an air supply device.

[0007] Preferably, the air supply device includes an air supply ring pipe, which is fixedly connected to the outer ring side wall of one end of the fan, and an air outlet pipe is fixedly connected to the side wall of the air supply ring pipe, one end of the air outlet pipe is connected to the air outlet end of the air pump, and an air inlet pipe is fixedly connected to the side wall of each atomizing nozzle, and each of the air inlet pipes is connected to the air supply ring pipe.

[0008] Preferably, a one-way valve is provided in each of the air inlet pipes.

[0009] Preferably, the inner side wall of each atomizing nozzle is provided with a spiral groove.

[0010] Preferably, a spray neck portion whose diameter gradually decreases and then increases is provided near one end of the atomizing nozzle.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] The device passes the rotating water flow containing air through the nozzle neck by first narrowing the diameter and then expanding it. This not only makes the sprayed water mist have a wider diffusion area but also has smaller droplets, thus achieving a better atomization effect and improving the dust removal efficiency.

[0024] See also Figures 1 to 4 In the embodiment of the utility model, a micro-mist dust suppression fog cannon includes a barrel body 6, a fan 7 is arranged in the barrel body 6, a water supply ring pipe 4 is fixedly connected to the side wall of one end of the barrel body 6, a water inlet pipe 5 is fixedly connected to the side wall of the water supply ring pipe 4, and a high-pressure pump (not shown) is connected to one end of the water inlet pipe 5. The high-pressure pump is used to pressurize the external water source and input it into the water inlet pipe 5. A plurality of atomizing nozzles 1 are fixedly connected to the side wall of the water supply ring pipe 4 and are arranged in a ring array. An air pump 9 is provided on the outer wall of the barrel body 6, and the air pump 9 is connected to the plurality of atomizing nozzles 1 through an air supply device. The air ring pipe 3 is fixedly connected to the outer ring side wall of one end of the fan 7 and the side wall of the air supply ring pipe 3.

[0025] Specifically, the air supply device includes an air supply ring pipe 3, which is fixedly connected to the outer ring side wall of one end of the fan 7. An air outlet pipe 8 is fixedly connected to the side wall of the air supply ring pipe 3. One end of the air outlet pipe 8 is connected to the air outlet end of the air pump 9. An air inlet pipe 2 is fixedly connected to the side wall of each atomizing nozzle 1. Each air inlet pipe 2 is connected to the air supply ring pipe 3. A one-way valve 10 is provided in each air inlet pipe 2. The one-way valve 10 only allows gas to enter the atomizing nozzle 1 from the air inlet pipe 2. When the air pump 9 is started, the compressed air can enter the air supply ring pipe 3 through the water supply ring pipe 4, and then enter the multiple atomizing nozzles 1 through multiple air inlet pipes 2, so that the outside air is mixed with the water flow in the atomizing nozzle 1.

[0026] The working principle of the utility model is:

[0027] When in use, firstly, the high-pressure water flow from the outside can be input into the water supply ring pipe 4 through the water inlet pipe 5, and then the high-pressure water flow enters into multiple atomizing nozzles 1 from the water supply ring pipe 4. The spiral groove 11 in the atomizing nozzle 1 can make the water flow generate a rotating centrifugal force. At the same time, the air pump 9 is started to let the compressed air enter into the air supply ring pipe 3 through the water supply ring pipe 4, and then enter into multiple atomizing nozzles 1 through multiple air inlet pipes 2. After the outside air is mixed with the water flow in the atomizing nozzle 1, when the rotating water flow containing air passes through the nozzle neck 12, due to the reduction and then expansion of the pipe diameter, after the water flow is sprayed out of the nozzle neck 12, the water flow mixed with the gas not only has a wider diffusion area, but also has smaller water droplets, thereby achieving a better atomization effect. Finally, the fine water mist can be diffused farther under the wind force of the fan 7, thereby improving the dust removal efficiency.
