The honeycomb ceramic carrier catalyst miniature coating machine comprises a first conveying pipe, a second conveying pipe, clamping dies, a drawing mechanism and an air blowing mechanism; the first conveying pipe is communicated with the second conveying pipe, clamping dies are arranged at the output end of the first conveying pipe and the input end of the second conveying pipe, the output end of the second conveying pipe is provided with a drawing branch pipe and an air blowing branch pipe, the drawing branch pipe is connected with the drawing mechanism, and the air blowing branch pipe is connected with the air blowing mechanism. In addition, the invention further provides a using method of the honeycomb ceramic carrier catalyst miniature coating machine, operation is simple, the soaking time of slurry in a honeycomb ceramic carrier hole can be controlled, the slurry can be coated into the honeycomb ceramic carrier hole quantitatively and evenly, and the coating quality and efficiency are improved.

Description

technical field [0001] The invention belongs to the technical field of coating equipment, and in particular relates to a honeycomb ceramic carrier catalyst micro-coating machine and a use method thereof. Background technique [0002] At present, with the promulgation and implementation of my country's air pollution prevention and control laws and regulations, the prevention and control of air pollution sources has become increasingly strict and urgent. As one of the main sources of atmospheric environmental pollution, motor vehicle exhaust emissions have attracted much attention for their purification treatment. [0003] As the core component of the vehicle exhaust purification device, the honeycomb ceramic carrier coated with catalyst materials plays a key role in the entire exhaust gas purification reaction. Its preparation process and preparation methods are directly related to the purification efficiency of the entire purification device. The preparation of the coated c...

Problems solved by technology

This coating method is easy to operate and does not limit the shape of the carrier. However, the honeycomb ceramic carrier needs to be completely immersed in the catalyst slurry, and the outer wall of the honeycomb ceramic will be adhered to the slurry. The load of the material is not uniformly controlled, the product consistency is poor, and the active coating slurry in the unit cell of the honeycomb ceramic carrier is unevenly distributed, resulting in the active coating powder blocking the honeycomb cell or falling off after firing, which seriously affects the test product. Testing, and at the same time unable to quickly promote the application of laboratory product data to the production line
