Description

Technical Field

[0001] This utility model relates to the field of flame retardant processing technology, specifically a washing device for flame retardant processing. Background Technology

[0002] Flame retardants are functional additives that impart flame-retardant properties to flammable polymers. They are primarily designed for flame retardancy in polymer materials. There are various types of flame retardants, categorized by application method into additive flame retardants and reactive flame retardants. Flame retardants increase the flame resistance of polymer materials and are mainly used in materials such as plastics, rubber, and fibers. Flame retardants exert their flame-retardant effect through several mechanisms, such as endothermic action, covering effect, inhibition of chain reactions, and suffocation effect of non-flammable gases. During the processing of flame retardants, the material needs to be filtered to form a filter cake. The wet filter cake is then placed in a washing tank with pure water to create a suspension, followed by heating, purification, and pressure filtration. After drying, the material is pulverized. When washing, stirring is usually required. A Chinese utility model patent (publication number: CN214529249U) discloses a washing device for the production process of aluminum-magnesium alloy flame retardant. Since the push block is hinged to the transmission belt, it will reverse at this time. The push block passes through the bottom of the support plate and reaches the bottom of the transmission belt. During this process, the stirring motor, rotating rod and stirring rod on the support plate move, which can stir most of the space inside the stainless steel reaction tank, making the stirring effect more uniform.

[0003] However, its structure still needs improvement, specifically as follows: the support plate only makes linear reciprocating motion, and with the rotation of the stirring rod, it is still difficult to cover the corner areas of the stainless steel reaction tank. When the flame retardant filter cake accumulates in the corner, the washing liquid cannot fully contact it, resulting in incomplete local washing and a high rate of impurity residue. Therefore, a washing device for flame retardant processing is needed to improve the above problems. Utility Model Content

A second air guide pipe is connected to the air outlet pipe of the air pump, and the second air guide pipe is connected to the air outlet pipe.

[0014] As a preferred embodiment of this utility model, both ends of the bottom of the support plate are fixed with movable wheels, and the bottom of the movable wheels makes rolling contact with the top of the cleaning tank.
