A polymer paint backflow protection device based on automatic operation of flow direction

Abstract

The invention relates to providing a polymer paint backflow protection device based on the automatic operation of the flow direction, which includes a feeding pipe, a movable seat connected to the top of the base in rotation, a blocking plate is movably inserted into the inside of the movable seat, and a through hole is opened inside the blocking plate. The outer side of the rotating shaft is movably sleeved with an impeller, the back of the rotating shaft is fixedly connected with a turntable, the ring side wall of the turntable is provided with evenly distributed driving rods, and the top of the movable seat is fixedly connected with a cylinder corresponding to the driving rods. When backflow occurs in the lower feeding pipe, the coating surges up to drive the impeller to rotate counterclockwise, the impeller drives the rotating shaft and the turntable to rotate, and the turntable drives the movable seat to rotate through the lever and cylinder, so that the movable seat rotates counterclockwise. When the slope section on the board is aligned, the blocking plate will be displaced, the through hole and the feeding pipe will be staggered, and the feeding pipe will be blocked to prevent the paint from continuing to flow out. waste problem.

Description

technical field [0001] The invention relates to the technical field of polymer coatings, in particular to a backflow protection device for polymer coatings that works automatically based on flow direction. Background technique [0002] Polymer coatings are mainly divided into solvent-based coatings and water-based coatings. Water-based coatings use water as a solvent and are in an amorphous liquid state at room temperature. After being applied, they can form substances with certain thickness and waterproof functions on the surface of the structure. Water-based coatings are widely used in the construction field due to their non-flammable, non-polluting, waterproof and breathable functions. [0003] Polymer water-based paints are generally stored in barrels. During the production, packaging and actual use, the paints are often loaded into barrels, and the produced paints are delivered to individual paint barrels through the feeding tube. Internally, when filling the bucket, i...

[0003] Polymer water-based paints are generally stored in barrels. During the production, packaging and actual use, the paints are often loaded into barrels, and the produced paints are delivered to individual paint barrels through the feeding tube. Internally, when filling the bucket, if the staff does not pay attention to observation, or the transmission of the paint bucket fails, causing a single paint bucket to stay under the feeding pipe for too long, it will cause the filling of the paint bucket to be too slow, and the paint will flow backwards. Bucket overflows, causing waste
