Description

Technical Field

[0001] The invention belongs to the technical field of concrete processing, and in particular relates to a concrete dust-proof feeding device. Background Art

[0002] Concrete dust-proof feeder is mainly used to transport concrete raw materials (such as cement, aggregate, etc.) from the storage area to the molding machine or mixing station, supplying molds for making or concrete mixing. This equipment greatly improves production efficiency and effectively reduces dust pollution through automated and continuous conveying methods; The concrete dust-proof feeder is mainly composed of a feeding device, a conveying pipeline, a dust-proof device and a control system. The feeding device usually includes a feeding hopper, a feeding motor, a feeding pulley, etc.; the conveying pipeline is used to transport the concrete material from the feeding device to the target location; the dust-proof device may include a dust collector, a sealing device, etc. to reduce dust emissions; the control system is responsible for the automatic operation of the entire equipment. When working, the concrete material is placed on the feeding device, and the feeding pulley drives the material into the conveying pipeline through the driving of the feeding motor. The material in the conveying pipeline moves forward under the action of gravity and friction and eventually reaches the target location. The dust-proof device collects the generated dust through the dust collector to prevent it from being discharged into the atmosphere; in the process of using the concrete dust-proof feeding device, the key is to efficiently and smoothly transfer the concrete raw materials through the feeding device. However, due to the easy agglomeration characteristics of concrete, it is very easy for the material to be blocked inside the spiral feeding pipe during this process. The traditional treatment method is to use filtering means to screen and break up the agglomerates in the concrete. Unfortunately, since concrete lumps often take a long time to solidify, traditional filtering methods often cannot completely achieve the screening and breaking effects. This not only increases the operating burden of the equipment, but also seriously affects the efficiency and continuity of feeding, thus restricting the smooth progress of the overall production process.
