Description

Technical Field

[0001] The utility model relates to the technical field of adhesive storage, in particular to an anti-coagulation device for storing water-based sandpaper coating adhesives. Background Technique

[0002] Water-based sandpaper coating adhesive is an environmentally friendly adhesive that is non-toxic and harmless and uses water as a dispersant. In recent years, it has become more and more popular due to the improvement of environmental protection standards. When storing water-based sandpaper coating adhesives, stratification is likely to occur due to standing, resulting in the precipitation and agglomeration of polymer adhesives at the bottom of the storage tank; it will also react with oxygen due to the presence of oxygen in the tank, causing coagulation of the water-based sandpaper coating adhesive. Content of the Utility Model

[0003] The purpose of the utility model is to overcome the above problems existing in the prior art and provide an anti-coagulation device for storing water-based sandpaper coating adhesives.

[0004] To achieve the above technical purpose and reach the above technical effect, the utility model is realized through the following technical solutions:

[0005] An anti-coagulation device for storing water-based sandpaper coating adhesives includes a storage tank for storing water-based sandpaper coating adhesives. A vertical partition is welded in the storage tank. The partition divides the interior of the storage tank into an annular storage cavity. Two low-speed submersible agitators arranged symmetrically about the center are installed in the storage cavity;

[0006] The top of the storage tank is provided with a feed pipe, a maintenance port, an air extraction pipe, and a gas filling pipe. A nut is screwed on the feed pipe. A maintenance cover is installed on the maintenance port. The air extraction pipe is connected to the air inlet of a vacuum pump through a gas transmission pipe equipped with a valve I. The gas filling pipe is connected to a gas storage tank filled with a protective gas through a gas transmission pipe equipped with a valve II;

[0007] The bottom of the storage tank is provided with a discharge pipe, and a valve III is installed on the discharge pipe.

[0008] Among them, two coaxial square steel pipes are welded between the partition and the side wall of the storage tank. A "U" - shaped clamp block is installed at the tail end of the low-speed submersible agitator with bolts. The square steel pipe is clamped between the clamp block and the tail end of the low-speed submersible agitator.

[0009] Among them, a support rod is welded on the tank body below the low-speed submersible agitator. The top of the support rod is welded with a U-shaped support groove, and the reducer of the low-speed submersible agitator is clamped into the support groove.

[0010] Among them, the longitudinal section of the bottom of the storage cavity is semi-circular.

[0011] Among them, both ends of the storage tank are semi-circular.

[0012] The bottom of the inspection cover is affixed with a circular rubber sealing gasket. When the inspection cover is installed on the inspection port, the rubber sealing gasket is sandwiched between the top of the inspection cover and the inspection port.

[0013] The storage tank is equipped with a steel support base welded to its bottom end, and the bottom end of the steel support base is welded with multiple support legs.

[0014] The beneficial effects of this utility model are as follows: The interior of the storage tank is divided into annular storage chambers by a partition. Two low-speed submersible propellers are installed in the storage chambers in a centrally symmetrical arrangement. The operation of the low-speed submersible propellers promotes the circulation of the water-based sandpaper coating adhesive in the storage tank along the storage chamber, preventing the polymer adhesive in the water-based sandpaper coating adhesive from settling and clumping at the bottom of the storage tank. After the storage tank is filled, the air in the storage tank is extracted by a vacuum pump, and then the protective gas in the gas storage tank is introduced into the storage tank to prevent solidification caused by the reaction between the oxygen remaining in the storage tank and the water-based sandpaper coating adhesive.
