Description

Technical Field

[0001] The utility model relates to the technical field of feeding devices, in particular to a safety feeding device for chemical production. Background Technique

[0002] In the process of chemical production, the design and use of a safety feeding device are crucial. The main function of this device is to ensure that all raw materials can be safely and accurately fed into the production line, avoiding safety accidents caused by inaccurate or unsafe feeding;

[0003] In the current technical system, the feeding of chemical raw materials mainly relies on the operation of a conveyor belt. The main advantage of this method is that it can achieve batch and continuous feeding, improving production efficiency. However, there is a key problem, that is, when feeding through a conveyor belt, it is difficult to adjust the conveying angle, which directly affects the convenience and efficiency of the feeding process.

[0004] First of all, the conveying angle of the conveyor belt is crucial for the accuracy and stability of feeding. There are various types of chemical raw materials, and the physical properties of each raw material are different, such as weight, particle size, fluidity, etc., which all determine their behavior during the feeding process. If the angle of the conveyor belt cannot be adjusted conveniently, it may lead to inaccurate feeding or material blockage due to an unsuitable angle for a specific raw material; secondly, the inability to conveniently adjust the angle of the conveyor belt will also affect the layout and space utilization of the chemical production line. In a limited space, angle adjustment can help us optimize the equipment layout, make the production line more compact, and improve space utilization. If the angle cannot be adjusted conveniently, additional space may be required to accommodate the operation of the conveyor belt, which will undoubtedly increase production costs and space waste. For this reason, we propose a safety feeding device for chemical production. Content of the Utility Model
