Highly toxic powder transportation and feeding equipment and method

Abstract

The invention provides a device and method for transporting and feeding toxic powder. The device is used for feeding toxic the toxic powder to a solution tank. The device comprises an inner stock bin, a screw feeder and a transporting box body, the inner stock bin and the screw feeder are located in the transporting box body, the inner stock bin is connected with the screw feeder, and an output end of the screw feeder is connected with a delivering pipeline, wherein the delivering pipeline is used for being connected with the solution tank. The combined using of the designed inner stock bin and the screw feeder is adopted, the danger that an operator operates through a hopper is avoided, operating safety of the operator is guaranteed, meanwhile, the inner stock bin and the screw feeder are arranged in the transporting box body, the need for transporting the toxic powder is met, in addition, the inner stock bin is connected with the screw feeder, the inner stock bin and the screw feeder can be integrally placed in and taken out of the box body, and a feeding system can be examined, repaired and maintained conveniently. The device and method for transporting and feeding the toxic powder has the advantages that the toxic powder is easy to feed and transport, and the device and method for transporting and feeding the toxic powder is safe relatively.

Description

technical field [0001] The invention relates to the metallurgical industry, in particular to a highly toxic powder transportation and feeding equipment and method. Background technique [0002] In the electroplating tin production line in the metallurgical industry, a highly toxic powder raw material called Na2CrO7 (sodium dichromate, commonly known as sodium red alum) needs to be used. Due to the highly toxic and harmful nature of Na2CrO7, it is generally stored in professional chemical companies. In the actual application of the project, according to the consumption status of Na2CrO7 raw materials on site, Na2CrO7 is often transported from the chemical plant to the user in bags or barrels, and then hoisted to the solution tank, and manually added to the feed hopper set on the top of the solution tank. . The main problems with this approach are: [0003] (1) It is easy to be lost and stolen during transportation, and there are hidden dangers such as easy to prevent moist...

AI Technical Summary

Problems solved by technology

[0003] (1) It is easy to be lost and stolen during transportation, and there are hidden dangers such as easy to prevent moisture and easy to leak;

[0004] (2) Due to the use of bags or barrels, it is difficult to put them on site. At the same time, due to the small amount of bags or barrels, frequent auxiliary hoisting is required, which increases the workload of auxiliary hoisting and the safety hazards of operators;

[0005] (3) Due to the need for manual timing and quantitative dosing, and the open operation through the hopper, it is easy to leak and cause pollution to the surrounding environment

Moreover, the labor safety of the operators cannot be guaranteed, and the physical damage and labor intensity of the operators are relatively high;

[0006] (4) Packing in bags or barrels will produce a lot of packaging waste, and there will be residual Na2CrO7 on the packaging, which will easily cause potential harm to the human body and potential pollution to the environment when exposed to the air
