Closed quantitative powder material self-control discharging system

Abstract

The invention relates to a closed quantifiable powder material self-control discharging system which comprises a bin body, a connecting part, a discharging part, a discharging conveying assembly and a control mechanism; a feeding pipeline is arranged at the upper end of the bin body, an electronic weighing mechanism is installed outside the bin body, and the connecting part is a flexible connecting mechanism; the discharging conveying assembly comprises a conveying motor and a discharging screw mechanism; the conveying motor is fixedly installed on the outer side of the discharging part; the lower end of the discharging part is connected with a discharging pipe; the discharging screw mechanism is installed between the discharging part and the discharging pipe; the conveying motor controls operation of the discharging screw mechanism; an air hammer is installed on the discharging pipe; and the electronic weighing mechanism, the conveying motor and the air hammer are all associated with the control mechanism. According to the automatic control discharging system, the situation that a cover is opened manually to dredge powder materials can be avoided, so that harm to human bodies and the environment due to dissipation of the powder materials is avoided, the labor intensity is reduced, and the production efficiency is improved; it is ensured that the powder materials meet the intermittent or continuous discharging requirement, and the production continuity and stability are ensured.

Description

technical field [0001] The invention relates to a closed automatic control feeding system for quantitative powder materials, which belongs to the technical field of chemical industry or food processing equipment. Background technique [0002] In the process of chemical products and food processing and production, the transportation of powdery materials is an indispensable process. Common powder material conveying methods mainly include conveyor belt conveying and screw conveying. Conveyor belt transportation is not sealed during the transportation process, which may cause material deterioration, leakage, and escape, resulting in waste of materials and great harm to the environment and personnel. For some powder materials that are easy to accumulate, simple screw conveying may cause the material to adhere to the warehouse wall and make it difficult to unload, which cannot meet the requirements for unloading, which may have a great impact on the subsequent process. For some ...

Problems solved by technology

Conveyor belt transportation is not sealed during the transportation process, which may lead to material deterioration, leakage, and escape, resulting in waste of materials and great harm to the environment and personnel

For some powder materials that are relatively easy to accumulate, simple screw conveying may cause the material to adhere to the warehouse wall and make it difficult to unload, which cannot meet the requirements for unloading, which may have a great impact on the subsequent process.

For some production processes with special process requirements, intermittent or continuous feeding may be required, and it is difficult for ordinary feeding devices to meet the production requirements
