Background

The production of the active carbon mainly comprises the working procedures of material preparation, grinding, granulation and forming, carbonization, activation, packaging and the like, wherein the activation working procedure is a key step in the production process of the active carbon. However, the automation degree of the existing activating procedure feeding process is extremely low, and CO poisoning and personal casualty accidents caused by the escape of smoke gas of manual material distribution at the feeding port of the activating furnace occur. At present, the material loading of the activation furnace is mostly lifted by adopting an electric hoist, and the operation steps are as follows:

placing the carbonized material ton bag on the ground of the activation furnace through a forklift, manually hooking, operating an electric hoist, hanging the ton bag to the platform of the charging opening of the activation furnace, opening a flue gas water seal cover plate of the activation furnace, manually shoveling the activated material to a material feeding opening, covering the flue gas water seal cover plate after the material is fed, and finishing the feeding process of the material feeding opening.

But does not substantially solve the following problems of the prior activating furnace feeding system: (1) no matter be material transportation or material loading cloth accomplish by artifical manual, degree of automation is low, and the cost of labor is high. (2) The discharge of the activation furnace is operated intermittently, the activation furnace needs to be filled with corresponding carbonized materials from a feeding port in the operation process, and a smoke water seal cover plate at the top of the activation furnace needs to be opened for feeding and distributing materials during feeding.

(3) the existing mode inevitably causes the abrasion of materials and the generation of flying dust no matter the carbonization material transfer process or the activation material loading process, not only causes certain economic loss, but also seriously influences the environmental sanitation and image problems of the factory simultaneously.

CN 110589828A discloses an activation measurement charging system, sets up the buffering feed bin in activation process and carbomorphism process and has solved the problem of artifical transportation of material.
