Description

A device for preventing blockages in chemical raw material conveying and filling tanks. Technical Field

[0001] This utility model relates to the field of chemical raw material conveying and filling technology, and in particular to a device for preventing material blockage in chemical raw material conveying and filling. Background Technology

[0002] Currently, chemical raw material conveying and filling typically involves placing the chemical raw materials into material tanks, then using pipes and valves to release and weigh the materials for conveying and filling. However, due to the special properties of many chemical raw materials, direct contact with metal is not permitted, and the materials are prone to cake formation and bridging. Therefore, automated conveying and filling of chemical raw materials cannot be achieved using existing chemical raw material conveying and filling equipment in the product logistics and filling process. Summary of the Invention

[0003] To solve the above-mentioned technical problems, this utility model designs an anti-blocking device for conveying and filling chemical raw materials.

[0004] The present invention adopts the following technical solution:

[0005] A device for preventing blockage in chemical raw material conveying tanks includes a logistics tank, which comprises a frame and a tank body. The tank body is fixed on the frame, and an inlet is opened at the upper end of the tank body. A stirring shaft is laterally rotatably connected to the lower part of the tank body. A stirring shaft sleeve is fitted over the stirring shaft. Multiple rows of stirring claws are evenly fixed along the circumference of the stirring shaft sleeve. The end of the stirring shaft is connected to a stirring motor for driving. A spiral conveying pipe is connected to the outlet at the lower part of the tank body. A conveying shaft is rotatably connected inside the spiral conveying pipe. The end of the conveying shaft is connected to a conveying motor for driving. A conveying shaft sleeve is fitted over the conveying shaft, and spiral blades are fixedly installed on the conveying shaft sleeve. A weighing outlet is opened at the bottom of the tail end of the spiral conveying pipe. A barrier layer is respectively provided on the inner surface of the tank body and the inner surface of the spiral conveying pipe.

[0006] Preferably, the stirring shaft sleeve and stirring claw are integrally molded from nylon.

[0007] Preferably, the conveying bushing and the spiral blade are integrally molded from nylon.

[0008] Preferably, the barrier layer is a plastic lining layer.

[0009] Preferably, a stirring reducer is installed between the stirring shaft and the stirring motor.

[0010] Preferably, a conveyor speed reducer is installed between the conveyor shaft and the conveyor motor.

[0011] Preferably, the multiple rows of stirring claws are staggered.

[0012] Preferably, a weighing device is installed at the weighing outlet.

[0013] The beneficial effects of this utility model are: (1) This utility model designs a device for preventing material blockage in chemical raw material conveying and filling. By setting up a plastic lining layer, nylon stirring shaft sleeve and stirring claw, as well as nylon conveying shaft sleeve and spiral blades, the material is prevented from directly contacting the metal, thereby realizing the automated conveying and filling of the chemical raw material, reducing the intensity of manual labor and lowering labor costs; (2) By setting up a double stirring device and a spiral feeding device, the problem of easy cake formation and bridging of materials, making them difficult to convey is solved.

[0017] The technical solution of this utility model will be further described in detail below through specific embodiments and with reference to the accompanying drawings:

[0018] Example: As shown in Figures 1 and 2, a device for preventing blockage in chemical raw material conveying tanks includes a logistics tank, which includes a frame 1 and a tank body 2. The tank body is fixed on the frame, and an inlet is opened at the upper end of the tank body. A stirring shaft 3 is laterally rotatably connected to the lower part of the tank body. A stirring shaft sleeve is fitted over the stirring shaft. Multiple rows of stirring claws 11 are evenly fixed along the circumference of the stirring shaft sleeve. The multiple rows of stirring claws are staggered. The end of the stirring shaft is connected to a stirring motor 4 for driving. A stirring reducer 5 is installed between the stirring shaft and the stirring motor. A spiral conveying pipe 6 is connected to the discharge port at the lower part of the tank body. A conveying shaft 7 is rotatably connected inside the spiral conveying pipe. The end of the conveying shaft is connected to a conveying motor 8 for driving. A conveying reducer 9 is installed between the conveying shaft and the conveying motor. A conveying shaft sleeve is fitted over the conveying shaft. Spiral blades 12 are fixedly installed on the conveying shaft sleeve. A weighing discharge port 10 is opened at the bottom of the tail end of the spiral conveying pipe. A barrier layer is provided on the inner surface of the tank body and the inner surface of the spiral conveying pipe.

[0019] The mixing shaft sleeve and mixing claws are integrally cast from nylon. The conveying shaft sleeve and spiral blades are integrally cast from nylon. The barrier layer is a plastic lining. A weighing device is installed at the weighing outlet. The tank body, spiral conveying pipe, mixing shaft, and conveying shaft are all made of 316L stainless steel.

[0020] In use, the material enters through the inlet on the tank. Considering that the material cannot directly contact metal and is prone to caking and bridging, making normal conveying and filling impossible, a dual-stirring method is adopted to solve the caking and bridging issues. After the material enters the hopper, the stirring shaft drives the stirring claws to move the caking and bridging material into the spiral conveying pipe. The conveying shaft drives the spiral blades to convey the material to the weighing outlet, where it is filled into a special container. The start and stop time of the conveying and stirring is controlled by a weighing sensor to ensure that the weight of the added material is consistent.

[0021] The embodiments described above are merely preferred solutions of this utility model and are not intended to limit this utility model in any way. Other variations and modifications are possible without departing from the technical solutions described in the claims.
