Description

Technical Field

[0001] The utility model relates to the technical field of anti-corrosion coating production, in particular to an exhaust gas treatment device for anti-corrosion coating stirring equipment. Background Art

[0002] Anti-corrosion coatings are an essential type of paint. Conventional anti-corrosion coatings are used to prevent corrosion of metals and other materials under normal conditions, protecting the service life of non-ferrous metals; heavy-duty anti-corrosion coatings are used in relatively harsh corrosive environments and have a longer protection period than conventional anti-corrosion coatings.

[0003] In the production process of anti-corrosion coatings, a variety of raw materials need to be mixed and stirred. During the production and stirring process, a large amount of volatile substances produce gases with certain toxicity. Therefore, in the production process of anti-corrosion coatings, the mixing tank needs to have a certain degree of sealing. However, after the production is completed, there will still be a lot of toxic and irritating gases remaining inside. The stirring production will also produce certain gases, which will cause the air pressure inside the tank to increase, so exhaust gas treatment work is required. Utility Model Content

[0004] The utility model aims at the defects in the prior art and provides an exhaust gas treatment device for anti-corrosion coating stirring equipment.

[0005] The utility model is realized through the following technical solutions:

[0010] The support frame effectively fixes the gas inlet pipe, thereby ensuring the installation effect of the gas nozzle on the top of the gas inlet pipe.

[0011] In a preferred embodiment of the utility model, the deflector is a funnel-shaped structure, and the deflector is arranged outside the top of the gas nozzle;

[0012] The deflector guides the air carrying the exhaust gas in the mixing tank so that it can be in full contact with the flame, thereby achieving a better exhaust gas treatment effect.

[0013] In a preferred embodiment of the utility model, the air inlet pipe is fixedly arranged at the bottom of the mixing tank, and its top passes through and extends to the inner side of the bottom of the mixing tank, and is sealed and fixed to the bottom of the mixing tank, and a valve is installed at one end of the air inlet pipe;

[0021] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more specific definition of the protection scope of the present invention. The directional terms mentioned in the present invention, such as "up", "down", "front", "back", "left", "right", "top", "bottom", etc., are only for reference to the directions of the attached drawings. Therefore, the directional terms used are used to illustrate and understand the present invention, rather than to limit the present invention.

[0022] like Figure 1-3 The exhaust gas treatment device for an anti-corrosion paint mixing equipment shown in the figure includes a mixing tank 1, an air intake pipe 2, a connecting pipe 3, an extension pipe 4 and an exhaust gas treatment device 5, the air intake pipe 2 is installed at the bottom of the mixing tank 1, the connecting pipe 3 is fixedly arranged at the top of the mixing tank 1, the bottom of the connecting pipe 3 passes through and extends to the inner side of the top of the mixing tank 1, the extension pipe 4 is installed at the top of the connecting pipe 3, and the exhaust gas treatment device 5 is installed at the top of the extension pipe 4. The exhaust gas treatment device 5 includes a mounting pipe 51, an exhaust hood 52, a gas inlet pipe 53, a combustion-supporting gas pipe 54, a support frame 55, a gas nozzle 56 and a guide cover 57. The mounting pipe 51 is connected to the top of the extension pipe 4, the exhaust hood 52 is fixedly arranged at the top of the mounting pipe 51, the gas inlet pipe 53 and the combustion-supporting gas pipe 54 are fixedly arranged on the outside of the mounting pipe 51, the support frame 55 is fixedly arranged on the inside of the exhaust hood 52, the gas nozzle 56 is fixedly arranged at one end of the gas inlet pipe 53, and the guide cover 57 is fixedly arranged on the inside of the exhaust hood 52.

[0023] Specifically, one end of the gas inlet pipe 53 passes through and extends to the inside of the mounting pipe 51, and the gas nozzle 56 is clamped on the inner side of the top of the gas inlet pipe 53. The gas nozzle 56 is vertically arranged, and the connection between the gas inlet pipe 53 and the air inlet pipe 2 is sealed. A clamping ring is arranged in the middle of the support frame 55, and the clamping ring in the middle of the support frame 55 is sleeved on the outside of one end of the gas inlet pipe 53. The guide cover 57 is a funnel-shaped structure, and the guide cover 57 is arranged on the outside of the top of the gas nozzle 56. The air inlet pipe 2 is fixedly arranged at the bottom end of the mixing tank 1, and its top passes through and extends to the inner side of the bottom of the mixing tank 1. It is sealed and fixed to the bottom of the mixing tank 1, and a valve is installed at one end of the air inlet pipe 2.

[0024] In this embodiment, when production work is carried out inside the mixing tank 1, first, the valve at one end of the bottom air inlet pipe 2 is in a closed state. If the anti-corrosion coating produced generates gas during the mixing process, resulting in excessive air pressure inside the tank, the gas can be discharged from the top of the connecting pipe 3 and enter the exhaust gas treatment equipment 5 through the extension pipe 4 for harmful gas purification. After the production is completed, the internal coating is discharged, but there will still be a lot of harmful gases remaining inside the mixing tank 1 that cannot be discharged and cleaned. Direct exhaust gas discharge will cause internal toxic and harmful gases to be discharged into the air, affecting the health of workers. At this time, an external air source is connected to the end of the air inlet pipe 2, and the valve is opened to discharge air into the mixing tank 1, so that the air is mixed with the internal exhaust gas, and the internal harmful gas concentration is reduced. After being discharged from the bottom connecting pipe 3, it is purified through the exhaust gas treatment equipment 5.

[0025] Furthermore, during the exhaust gas treatment process, the fuel gas enters the installation pipe 51 through the fuel gas inlet pipe 53, and is ejected from the gas nozzle 56. The ignition device ignites the fuel gas, and the fuel gas pipe 54 enters the fuel gas and mixes with the exhaust gas discharged from the mixing tank 1. The burned fuel gas is ignited, so that the harmful gas is burned and purified. In this process, the mixed gas is guided and shielded by the deflector 57, so that the gas is better in contact with the flame, thereby ensuring a complete reaction and achieving a more ideal purification effect, thereby reducing the volatile harmful gases entering the air and affecting the health of workers, ensuring the production environment.

[0026] It should be noted that the parts not covered in the present invention are the same as the prior art or can be implemented by the prior art; the various drives in the present invention can be implemented by corresponding power structures such as cylinders, oil cylinders, electric cylinders, motors, etc. in combination with connecting rods, guide rods, etc., and are not limited to the description in the specification and the structures in the drawings.
