Description

Technical Field

[0001] The utility model relates to the technical field of paint spraying and coating production, in particular to a ventilation structure for a coating line. Background Art

[0002] At present, painting is a material protection technology that uses paint to form an organic coating on the surface of a base material, which can prevent rust and corrosion. Currently, existing painting workshops usually have ventilation devices, and the ventilation devices of existing painting workshops generally directly exchange indoor and outdoor air.

[0003] The existing patent (Announcement No.: CN214148232U) proposes a ventilation structure for a coating line, including an automobile coating workshop and a ventilation mechanism, the automobile coating workshop is composed of a front end plate, a rear end plate, a side plate and a top plate, the ventilation mechanism is fixedly installed on the top of the automobile coating workshop, the ventilation mechanism includes a first ventilation device and a second ventilation device, the first ventilation device includes a first suction duct and a second suction duct, the first suction duct and the second suction duct are both installed with suction devices on the top, the suction device and the drive motor are mutually driven and connected, and the suction device is connected to the driving motor on the top of the first suction duct. A first ventilation duct is fixedly connected to one side of an air suction duct, and the first ventilation duct and the first air suction duct are interconnected. A HEPA filter is installed inside the first ventilation duct, and the HEPA filter can effectively filter out PM2.5, haze and other impurities in a car paint shop. An activated carbon filter is installed at the air outlet, and the activated carbon filter can absorb exhaust gas, odor, toluene and TVOC, and can quickly kill various bacteria in the air, and the emission is safe and pollution-free. The utility model has the advantages of good purification effect, low cost and operation and maintenance cost, and no pollution to the environment.

[0004] The ventilation structure of the above-mentioned coating line cannot adjust the position of the ventilation components during use, resulting in a long ventilation interval for smaller molds, making it impossible to concentrate the wind force, thereby affecting the ventilation and heat dissipation effect. When ventilation is used, when there are impurities in the air in the workshop, the wind generated by the ventilation components will blow the impurities onto the molds that have not been completely cooled. Therefore, we propose a ventilation structure for coating lines to solve the above problems. Utility Model Content

Furthermore, the fan can be driven up and down by the push rod to increase or decrease the distance between the fan and the mold, so as to adapt to molds of different heights and prevent poor ventilation effect caused by excessive or small distances, thereby increasing the practicality of the device in use.

[0020] 2.

Further, through the atomizing nozzle, under the action of the water pump, the water in the water tank is pumped into the atomizing nozzle, and is sprayed out after being atomized by the atomizing nozzle, so that a separation wall is formed on both sides of the mounting frame to prevent unfiltered air from directly contacting the mold, and the filter frame and the filter box are of a split structure. The advantage of the split structure is that it is more convenient to clean the filter element later. BRIEF DESCRIPTION OF THE DRAWINGS
