Description

Paint spray water curtain cabinet with automatic exhaust gas treatment function

technical field

The utility model relates to the technical field of environmental protection, in particular to a paint spraying water curtain cabinet with the function of automatic waste gas treatment.

Background technique

At present, the "water curtain cabinet" equipment is commonly used in the treatment of spray paint exhaust gas. The principle is to circulate spray water to generate water curtain to settle the water-soluble or particles of paint mist, so as to realize the separation of most of the paint mist, but it is necessary to completely eliminate disturbing paint. If there is no smell, it is still necessary to install materials and equipment to deal with paint smell at the equipment discharge port.

The existing "water curtain cabinet" has a certain concentration of exhaust gas, which often increases the processing materials of subsequent equipment and the power of operating equipment. A treatment method for the exhaust gas of the "water curtain cabinet" is: a discharge nozzle is provided on the top of the "water curtain cabinet", and filter cotton is arranged in the discharge nozzle, and the residual paint mist and paint smell enter the filter cotton and are intercepted by the axial flow The fan draws out from the discharge nozzle. The biggest disadvantage of this kind of equipment is: because the paint mist is viscous, the filter cotton is blocked and needs to be replaced in time, otherwise the wind resistance of the fan will increase and the life of the motor will be affected, and the replacement of filter cotton will increase labor and material costs.

Contents of the invention

The purpose of this utility model is to provide a paint spraying water curtain cabinet with the function of automatic waste gas treatment, which can improve the treatment efficiency and the purification effect of residual paint mist and paint smell. In order to achieve the above purpose, the utility model adopts the following technical solutions:

The paint spraying water curtain cabinet with the function of automatic waste gas treatment includes a cabinet body, a first circulating water pump, a working support, a water tank, a nozzle, an exhaust gas treatment device and a second circulating water pump. The inside of the cabinet is provided with a working support. There is a water tank, and a nozzle is provided directly above the water tank, and the first circulating water pump is arranged outside the cabinet to connect with the water tank, and the bottom of the cabinet is provided with an exhaust gas outlet, and the exhaust gas outlet is connected to the exhaust gas treatment device; The exhaust gas treatment device includes a cyclone, a plastic ball layer, a spray assembly, a zeolite layer and a treatment outlet from bottom to top, and the spray assembly is connected to the second circulating water pump.

Preferably, swirl fins are provided at both ends of the swirl cylinder.

Further, the spray assembly includes a spray pipe and a number of evenly distributed spray heads arranged under the spray pipe, and the spray pipe is connected to the second circulating water pump.

Further, a grille plate is also included, and said grille plate is arranged at the bottom end of the exhaust gas treatment device and is located below the cyclone.

Due to the adoption of the above structure, the utility model has the following beneficial effects: the utility model enters the waste gas generated by spraying paint into the waste gas treatment device through the bottom of the cabinet body to generate swirl and turbulent flow, which improves the contact time with the spray liquid, and through The zeolite layer is adsorbed, and the purification effect is good, and the utility model has a long service life and is easy to maintain.

detailed description

In order to make those skilled in the art better understand the technical solution of the utility model, the utility model will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

As shown in Figure 1, the utility model discloses a paint spraying water curtain cabinet with the function of automatic waste gas treatment, including a cabinet body 1, a first circulating water pump 2, a working support 3, a water tank 4, a nozzle 5, a waste gas treatment device 6 and The second circulating water pump 7.

Cabinet body 1 is provided with working support 3, and the inner side of working support 3 is provided with water tank 4, and water tank 4 is provided with sprinkler 5 directly above, and the first circulating water pump 2 is located at outside the cabinet and is connected with water tank 4. A waste gas outlet is provided at the bottom of the cabinet body 1, and the waste gas outlet is connected with the waste gas treatment device 6.

As shown in Fig. 2, the waste gas treatment device 6 includes a fence plate 61, a swirl tube 62, a plastic ball layer 64, a spray assembly, a zeolite layer 67 and a treatment outlet 68 from bottom to top, and the two ends of the swirl tube 62 are arranged Swirl plate 63 is arranged. The spray assembly includes a spray pipe 65 and four uniformly distributed spray heads 66 arranged below the spray pipe 65 , and the spray pipe 65 is connected with the second circulating water pump 7 .

The working principle of the utility model is as follows: the workpiece to be painted is placed on the working support 3 of the cabinet 1, the first circulating water pump 2 is started, and the painting is carried out. The waste gas generated during the painting process of the workpiece is absorbed in the water tank 4 by the water curtain ejected from the nozzle 5, and the residual paint mist and paint smell enter the bottom of the waste gas treatment device 6 from the waste gas outlet. The exhaust gas entering the exhaust gas treatment device 6 quickly enters the swirl tube 62 and swirls under the action of the swirl fins 63 . Turbulent flow is then performed through the layer 64 of plastic spheres. Start the second circulating water pump 7, the spray liquid enters the four spray heads 66 from the spray pipe 65 to spray the plastic ball layer 64, and the spray liquid part falls from the plastic ball layer 64 to the bottom of the exhaust gas treatment device 6, passes through the fence Plate 61 is discharged after the dirt blocking effect. The residual waste gas after spraying is adsorbed by the zeolite layer 67 . The purified trace residual exhaust gas is finally discharged from the treatment outlet 68 .

To sum up, the utility model improves the existing water curtain cabinet to effectively purify the exhaust gas from spraying paint, and is suitable for popularization and application.

The above is only a preferred embodiment of the utility model, but the scope of protection of the utility model is not limited thereto, and any person familiar with the technical field can easily think of All changes or replacements should fall within the protection scope of the present utility model.
