Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of paint impurity removal and filtering, in particular to a polyurethane paint impurity removal and filtering device. Background Art
[0002] Polyurethane coating is a two-component coating composed of isocyanate prepolymer and hydroxyl-containing resin. During the production or storage process, dust, particles or other impurities in the environment will be mixed into the coating. Therefore, it is necessary to use an impurity removal device to remove the impurities mixed in the coating to ensure the quality of the coating and the subsequent spraying appearance effect.
[0003] The existing paint impurity removal and filtering device is mainly composed of a tank body, a filter screen, a feed pipe, a discharge pipe and a vibration mechanism. When filtering impurities in the paint, the paint to be screened is first put into the tank body through the feed pipe, and then the vibration mechanism is used to make the tank body drive the filter screen to shake back and forth. Through the action of the filter screen, the paint without impurities can quickly flow through the filter holes into the bottom of the tank body, and finally be discharged through the discharge pipe. The impurities are intercepted on the filter screen, so that the impurities in the paint can be filtered and removed.
[0004] The existing paint impurity removal and filtering device cannot adjust the feed amount when filtering and removing impurities, which can easily lead to excessive or too fast feeding, making it impossible for the filtering and screening equipment to process in time, resulting in poor filtering and impurity removal effect; therefore, a polyurethane paint impurity removal and filtering device is proposed to address the above problems.
