Description

Technical Field

[0001] The utility model relates to the technical field of transfer pumps, and particularly relates to a pump for conveying high-viscosity adhesives. Background Art

[0002] An adhesive is a substance with good adhesion performance, which connects objects by surface adhesion through adhesive force and cohesive force. During the production of adhesives, various raw materials need to be mixed and stirred first, and then conveyed to the outside through a transfer pump.

[0003] During the transportation process of the existing transfer pump, in relatively cold weather, the adhesive will be cooled, affecting its normal transportation. The existing transfer pump is provided with heating coils inside the pump body to heat the pump body. However, the heat conduction performance of some pump bodies is not good, resulting in a slow heating speed, and still some adhesives will be cooled, affecting normal transportation.

[0004] The existing patent (Publication No.: CN217898169U) discloses an adhesive product transfer pump. The driving motor drives the double-screw conveyor rod to rotate. The two double-screw conveyor rods rotate towards each other, conveying the adhesive from the liquid inlet to the liquid outlet, and discharging it outward from the liquid outlet to the next process. A heating pipe is spirally arranged near the inner wall of the pump body, and the inside of the pump body is heated through the heating pipe, so as to avoid the effect that the adhesive cannot be transported due to cooling during the transportation process. At the same time, because the heating pipe is close to the inner wall of the pump body and a metal layer is provided for heat conduction, the heating speed is increased.

[0005] Regarding the above problems, the existing patent gives a solution, but it is not convenient to filter the impurities inside the adhesive. During the production, storage or transportation of adhesives, some solid particles, fibers and other impurities may be mixed in. Due to poor filtering effect, the impurities may easily get stuck in the gap between the double-screw conveyor rod and the pump body, resulting in the rotation of the conveyor rod being blocked, affecting the adhesive transportation efficiency, and reducing the practicability of the device.

[0006] Therefore, a pump for conveying high-viscosity adhesives is proposed. Summary of the Utility Model
