Dustproof elevating device and concrete production apparatus comprising same

Abstract

The invention relates to a concrete production apparatus, especially to a dustproof elevating device for the concrete production apparatus. The invention aims at providing a dustproof elevating device which can reduce the pollution to outside caused by the escape of dusts during aggregate elevation. Thus, the invention proposes the technical proposal as follow: a dustproof elevating device comprises an elevating rail and an elevating hopper, wherein the elevating rail comprises an elevating hopper feeding area, an elevating hopper elevating area, an elevating hopper overturning area and an elevating hopper discharging port area, and the elevating rail is provided with a dustproof device isolating the elevating rail from outside. Compared with the prior art, the dustproof elevating device has the following advantage: owing to the arrangement of the dustproof device on the elevating rail, aggregates can be elevated in a closed way, further reducing the pollution to outside caused by the escape of dusts.

Description

technical field [0001] The invention relates to concrete production equipment, in particular to a dust-proof lifting device for concrete production equipment. Background technique [0002] In concrete production, the dust generated when various formula materials are unloaded is the main cause of environmental pollution in the mixing station. At present, the domestic requirements for the environmental protection performance of mixing plant products are getting higher and higher. From the perspective of the entire production process of the mixing plant, the dust pollution generated during the transportation of aggregates is the largest. Because the belt and hoist are exposed to the air during transportation, when the hoist is unloading, positive pressure is generated in the main machine due to the unloading of the aggregate into the main machine, and the air quickly overflows from the feeding port to blow up the dust in the aggregate. , thereby polluting the environment of t...

AI Technical Summary

Problems solved by technology

Because the belt and hoist are exposed to the air during transportation, when the hoist is unloading, positive pressure is generated in the main machine due to the unloading of the aggregate into the main machine, and the air quickly overflows from the feeding port to blow up the dust in the aggregate. , thereby polluting the environment of the main building

For a long time, it will cause dust accumulation on the guide rail and the feed port of the main engine, and wear parts, which will affect the service life

[0003] At present, the mixing station is designed with a dust collection device, which can remove the dust while balancing the positive and negative pressure, but most of them are arranged on the main machine, and the dust collection effect on the elevator is not obvious
