Bulk transportation station flow guide equipment with nitrogen atmosphere material oxidation prevention function

Abstract

The invention provides bulk transportation station flow guide equipment with a nitrogen atmosphere material oxidation prevention function. The equipment comprises a head protection cover, a transportation station transition segment, a chute, a material blocking plate, a receiving conveying belt and a feeding belt conveyor; the transportation station transition segment is located between the head protection cover and the chute and is linked with a discharging opening of the head protection cover; a lower material blocking plate is arranged below the material blocking plate inside the transportation station transition segment; and the material blocking plate and the lower material blocking plate are arc-shaped plates, the cross sections of the material blocking plate and the lower material blocking plate are in U shapes, the lower material blocking plate is of an opening restraining structure with a large feeding opening and a small discharging opening, the concave arc face of the material blocking plate faces the feeding belt conveyor, and the concave arc face of the lower material blocking plate is upward. The two sides of the conveying belt are each provided with an air nozzle, the air nozzles are connected with an air tank through hoses, and nitrogen is contained in the air tank. According to the flow guide equipment, nitrogen atmosphere is arranged and used to protect the materials, the materials are prevented from being oxidized in the transportation process, the practicability is high, the effect is stable and reliable, and the higher economic value is achieved.

Description

technical field [0001] The invention relates to a diversion device of a bulk material transfer station with the function of preventing material oxidation in a nitrogen atmosphere. Background technique [0002] The bulk material transfer station diversion equipment with nitrogen atmosphere anti-oxidation function is mainly used in power plants, steel mills, coal mines, wharfs and chemical industries. Since the distance of bulk materials to the destination may be several kilometers away, and the terrain has different ups and downs during the transportation, designers usually set up several transfer stations during the transportation. [0003] The existing diversion equipment of bulk material transfer station with nitrogen atmosphere anti-oxidation function such as figure 1 As shown, it includes: a head shield 1, a baffle plate 4 installed in the head shield 1 that can be adjusted left and right according to the water content of the bulk material, a material guide groove 5 t...

AI Technical Summary

Problems solved by technology

The material flow collides with the inner wall of the chute during the descending process, and slides along the inner wall surface onto the receiving conveyor belt, generating a large amount of dust at the outlet of the chute, which pollutes the environment

The diversion equipment of the existing bulk material transfer station with nitrogen atmosphere anti-oxidation function does not have a centering device, and the bulk material will be unevenly distributed on the receiving conveyor belt after falling, which will easily cause the conveyor belt to deviate, and the inclination angle of the inner wall of the chute 3 is too high Small, the impact angle between the material flow falling into the chute and the wall surface is too large, resulting in a large impact force, accelerating the wear-resistant liner wear on the wall surface and generating fouling areas
