Description

Technical Field

[0001] The utility model relates to the technical field of spray filtering equipment, in particular to a spray filtering device. Background Art

[0002] At present, there are a lot of large particles of gas and debris in the process of profile cutting and workpiece grinding. The particles and debris will be discharged with the gas, which is easy to aggravate environmental pollution. Therefore, before the gas is discharged, we will spray and filter it. However, the main problem of the existing spray filtering equipment when in use is that the gas flows too fast (or part of the gas will gather and flow), so that part of the gas flows away without completely contacting the spray water, resulting in a small amount of particles and debris in the discharged gas, thereby reducing the use effect of the existing spray filtering equipment. For this reason, we propose a spray filtering device. Utility Model Content

[0007] The beneficial effects of the utility model are:

[0008] Compared with the prior art, the utility model is provided with a rotating barrel and guide vanes.

[0013] The specific implementation of the utility model is further described below in conjunction with the accompanying drawings:

[0014] like Figure 1-3 As shown,

[0015] A spray filtering device comprises a device body 1, a flow guide mechanism 2, a spray mechanism 3 and an exhaust fan 4; the flow guide mechanism 2 comprises a rotating barrel 5 and a guide vane 6, the rotating barrel 5 is fixedly installed inside the device body 1, the guide vane 6 is fixedly installed at the air outlet of the rotating barrel 5, and the exhaust fan 4 is fixedly installed inside the device body 1 and above the flow guide mechanism 2; the spray mechanism 3 comprises a spray head 7, and the spray head 7 is arranged between the exhaust fan 4 and the flow guide mechanism 2; the number of the spray heads 7 is several, and they are arranged at equal intervals.

[0016] As a preferred embodiment, the rotating barrel 5 is in a spiral structure. The purpose of this design is to prolong the gas flow time so that the gas can better contact with the spray water later.

[0017] As a preferred embodiment, the guide vane 6 is in a fan blade structure. The purpose of this design is to enable the gas to be dispersed evenly (multiple blades are provided on the guide vane 6, the distance between adjacent blades is the same, and each blade is inclined), so that the gas can fully contact with the spray water, and the large particles of dust and debris in the gas are thoroughly filtered, and the filtering effect is better.

[0018] As a preferred embodiment; the spray mechanism 3 also includes a water tank 8, a water pump 9 and a spray pipe 10; a water pump 9 is fixedly installed on the outside of the device body 1, and a water tank 8 is fixedly installed on the inner bottom of the device body 1, the water inlet end of the water pump 9 is connected to the water tank 8 through a pipeline, and the water outlet end of the water pump 9 is connected to the spray pipe 10, the spray pipe 10 extends to the inside of the device body 1, and the spray head 7 is installed on the spray pipe 10; by providing the water tank 8, the water pump 9 and the spray pipe 10, the spraying process is a cyclic operation, the spraying water can be reused, thereby saving water resources and reducing costs.

[0019] As a preferred embodiment, an air inlet nozzle 11 is installed at the air inlet of the rotating barrel 5; by providing the air inlet nozzle 11, an external gas pipeline can be connected to facilitate the discharge of the gas to be filtered into the interior of the rotating barrel 5; and, the shape of the air inlet nozzle 11 is rectangular, which can increase the gas discharge volume.

[0020] As a preferred embodiment, a demister 12 is fixedly installed between the spray head 7 and the exhaust fan 4. By providing the demister 12, water mist in the gas can be removed. Since there is more water mist in the gas after spraying, it needs to be removed. In this embodiment, four demisters 12 are arranged in a left-right arrangement, which can achieve efficient demisting.

[0021] As a preferred embodiment, an air outlet cap 13 is fixedly mounted on the top surface of the device body 1; it can be understood that the air outlet cap 13 is provided with dense through holes, which can facilitate the discharge of a large amount of gas.

[0022] As a preferred embodiment, the water tank 8 is also connected to a water inlet pipe and a drain pipe 14. The water inlet pipe and the drain pipe 14 are provided, the water inlet pipe is used to supply or replenish water to the water tank 8, and the drain pipe 14 is used to discharge the water in the water tank 8 (after a period of use, the water quality in the water tank 8 deteriorates and needs to be replaced). The whole process does not require manual operation, and only requires external water pipes, thereby reducing the labor expenditure of workers.

[0023] The working principle of the utility model is as follows: first, the exhaust fan 4 is turned on to form a negative pressure inside the device body 1 to extract gas, and then, the gas to be filtered is discharged into the rotating barrel 5 through the air inlet nozzle 11, and the gas to be filtered will continuously flow into the deep part of the rotating barrel 5 and reach the guide vane 6, and the gas will be dispersed and discharged through the guide vane 6. At this time, the spray water sprinkled by the spray head 7 can effectively contact the gas, and completely filter out large particles of dust and debris in the gas, and the filtering effect is better. The gas filtered by the spray will reach the demister 12, and the water mist in the gas can be effectively removed after passing through the demister 12. Finally, the filtered gas is discharged through the air outlet cap 13.

[0024] It should be pointed out that the main problems existing in the prior art are: the gas flows too fast, or part of the gas gathers and flows, so that part of the gas flows away without completely contacting the spray water, resulting in a small amount of particles and debris in the discharged gas, thereby reducing the use effect of the existing spray filtration equipment;

[0025] Therefore, after the improvement of the present application, by providing a rotating barrel 5 and a guide vane 6, the rotating barrel 5 has a spiral structure, which can prolong the gas flow time, and the guide vane 6 can make the gas disperse evenly, so that the gas can fully contact with the spray water, and the large particles of dust and debris in the gas can be thoroughly filtered, and the filtering effect is better.

[0026] The above implementation modes are merely descriptions of the preferred implementation modes of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary engineering and technical personnel in the field shall fall within the protection scope determined by the claims of the present invention.
