Description
Technical Field
[0001] The utility model relates to the field of coating processing equipment, in particular to a sealed high-speed mixing tank. Background Art
[0002] Sealed high-speed mixing tanks are usually used in the material mixing process in industrial production. They have the function of quickly and efficiently mixing materials of different components. In high-speed mixing tanks, different mixing mechanisms are usually used, such as agitators, scrapers, etc., to achieve material mixing. At the same time, high-speed mixing tanks also have the characteristics of good sealing and easy operation, which can ensure that the materials are not contaminated by the outside world during the mixing process.
[0003] When the existing sealed high-speed mixing tank is used to mix powder coatings, residual powder is easily adsorbed on the inner wall of the tank body, causing coating loss. During the next mixing operation, the remaining powder from the previous mixing operation will also be mixed into the tank. The usual way to clean these powders is to open the sealed cover and use industrial compressed air to blow them away and collect them. However, this method will cause foreign impurities to appear in the mixed coating during cleaning.
[0004] The technical problem to be solved by the present application is: how to use industrial compressed gas to clean the inside of a mixing tank under closed conditions. Utility Model Content

[0015] The beneficial effects of the utility model are:
[0016] 1) Using industrial compressed gas to clean the mixing tank under closed conditions can effectively remove residues, improve production quality and safety, and ensure that the raw materials used in this operation can be fully utilized. The high-speed flow and pressure of compressed gas can flush out the residual powder in the tank to ensure that the next batch of raw materials is not contaminated.
[0017] 2) The high-speed flow of compressed gas can quickly remove residues, reduce cleaning time, and improve production line utilization. There is no need to wait for the solvent to evaporate, saving cleaning time and labor costs. At the same time, the cleaning process is simple and fast, reducing production downtime and improving production efficiency. This efficient cleaning method helps to optimize the production process and improve production efficiency and capacity.
[0018] 3) Using industrial compressed gas to clean the mixing tank under closed conditions does not require the use of chemical solvents, avoiding the emission of harmful substances and environmental pollution. The high-speed flow of compressed gas can quickly flush out the residues to avoid the impact of the residues on the environment. At the same time, the cleaning process does not require a large amount of water resources, reducing water resource consumption and wastewater treatment costs. BRIEF DESCRIPTION OF THE DRAWINGS
