Description

Technical Field

[0001] This utility model relates to the field of rubber conveyor belt production and processing technology, specifically a circulating stirring device for rubber conveyor belt production and processing. Background Technology

[0002] In the production of rubber belts, it is necessary to impregnate the rubber belts with slurry. The process is usually as follows: after the rubber belt is impregnated in the impregnation tank, it is then plasticized in the plasticizing box to complete the impregnation and plasticizing operation. The viscosity of the slurry is extremely critical, and the slurry needs to be continuously stirred.

[0003] The existing circulating mixing devices for rubber belt production and processing still have shortcomings. It is inconvenient to pump the liquid rubber settled at the bottom of the mixing tank to the top of the mixing tank for circulating mixing, which makes it easy for the liquid rubber at the bottom to be mixed unevenly, affecting the production quality of rubber conveyor belts. Moreover, the mixing effect is poor due to the stirring rod alone, which further reduces the production quality of rubber conveyor belts in the later stages.

[0004] Therefore, we propose a circulating mixing device for rubber conveyor belt production and processing. Utility Model Content

[0005] The purpose of this invention is to provide a circulating mixing device for the production and processing of rubber conveyor belts, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a circulating mixing device for rubber conveyor belt production and processing, comprising a mixing tank, a mixing shaft rotatably connected to the middle of the top of the mixing tank, a feed inlet located on one side of the mixing shaft at the top of the mixing tank, a drive motor fixedly installed on the top of the mixing tank on the other side of the mixing shaft, the output end of the drive motor being connected to the top of the mixing shaft, a first mixing blade fixedly installed on the outer circumferential surface of the mixing shaft, a second mixing blade fixedly installed on the outer circumferential surface of the mixing shaft wrapping around the first mixing blade, a fixing ring fixedly installed at the upper and lower ends of the second mixing blade at the mixing shaft, a connecting plate fixedly installed on the outer circumferential surface of the fixing ring, a fixing frame fixedly installed on the side of the connecting plate, a side wall scraper fixedly installed on the side of the fixing frame, the other end of the fixing frame being fixedly installed to the middle of the scraper, and the end of the side wall scraper slidingly contacting the inner wall of the mixing tank.

[0007] Optionally, a discharge pipe is fixedly installed in the middle of the bottom of the mixing tank, and a valve is provided at the bottom of the discharge pipe. The bottom of the mixing tank is funnel-shaped, and the discharge pipe is located at the lowest point of the bottom of the mixing tank.

[0008] Optionally, a lower scraper is fixedly installed at the bottom of the lower fixing ring, and the bottom of the lower scraper slides in contact with the bottom of the mixing tank.

[0009] Optionally, a first bevel gear is fixedly installed at the output end of the drive motor, and a second bevel gear located above the mixing tank is fixedly installed at the top of the stirring shaft, with the first bevel gear meshing with the second bevel gear.

[0010] Optionally, a circulating pump is fixedly installed at the bottom of the mixing tank on one side of the discharge pipe. The inlet of the circulating pump is fixedly installed to one side of the discharge pipe through a conduit. A guide pipe is fixedly installed at the outlet of the circulating pump. The other end of the guide pipe is fixedly installed to the top of the side of the mixing tank. The conduit at the inlet of the circulating pump is located above the valve. The diameter of the guide pipe is smaller than the diameter of the discharge pipe.

[0011] Optionally, an elastic arc plate is provided between the fixed frame and the side wall scraper, and the fixed frame, the side wall scraper and the elastic arc plate are arranged concentrically.

The first stirring blade and the second stirring blade rotate in opposite directions.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This circulating mixing device for rubber conveyor belt production and processing uses a side wall scraper to drive a motor to rotate the mixing shaft. The first and second mixing blades, which rotate in opposite directions, push the rubber inside the mixing tank in opposite directions, thereby creating turbulence in the fluid inside the mixing tank and improving the mixing effect. At the same time, the side wall scraper continuously scrapes the side wall of the mixing tank, resulting in better mixing and improving the quality of subsequent rubber conveyor belt production.

[0015] This circulating mixing device for rubber conveyor belt production and processing uses a circulating pump. During mixing, the circulating pump transports the rubber at the bottom to the top of the mixing tank through a guide pipe for circulating mixing, making the mixing more uniform and comprehensive, and will not affect the quality of the rubber conveyor belt production in the later stages.
