Description

Closed dust recovery belt conveyor

Technical Field

The utility model relates to a belt conveyor, especially a belt conveyor is retrieved to canned type dust.

Background

The belt conveyer, also called as rubber belt conveyer, consists of mainly middle frame, conveyer belt, carrier roller, tensioner, transmission unit, etc. The main operation principle is that the closed conveying belt is tightly sleeved on the two end point rollers, and the roller driving the conveying belt to rotate is called as a driving roller (transmission roller); the other is referred to as a direction-changing drum, which simply changes the direction of movement of the conveyor belt. The driving roller is driven by the motor through the speed reducer, and the conveying belt is dragged by the friction force between the driving roller and the conveying belt. The driving roller is generally arranged at the discharging end to increase the traction force and facilitate the dragging. The material is fed from the feeding end close to the tail part, falls on the rotating conveying belt, and is conveyed to the discharging end by the friction drive of the conveying belt to be discharged. The continuous motion of the conveyer belt is used to convey powdery and granular articles, and the conveyer belt has high speed, smooth running, low noise and capacity of conveying articles up and down slopes. The belt conveyor is arranged up and down, and when viewed from the upper side, a material conveying section at the upper side is called a running section, and when viewed from the lower side, the material conveying section at the lower side is called a return section.

The belt conveyor is a conveying device which has large conveying capacity, low maintenance cost, convenient arrangement and quite common application, most of conveyed materials are powdery and granular materials, and a large amount of dust, especially the positions of a feeding point and a discharging point, can be raised in the conveying operation process of the device, but is mainly troubled by the problems of dust pollution and return leakage at present, and the requirements on the environment are higher and higher along with social development, and the dust protection and leakage scattering of the belt conveyor are important subjects. The currently adopted method for solving the problems is as follows: 1. the whole sealing cover shell which is not subjected to sealing 2 and steel plate assembling welding in exposed conveying or the whole sealing cover shell is made by adopting a bolt locking mode of galvanized plates and color steel plates. However, these methods have several problems:

1) exposed transport does not seal up, leads to a large amount of raise dusts in the equipment transportation vestibule building, and operational environment is poor, influences other equipment operation, needs a large amount of manual works to sweep the clearance, is unfavorable for the environmental protection, and the environmental protection index can not reach standard, can not standardize large-scale production, and market does not allow this kind of operating mode to exist.

2) The integral sealing cover has the disadvantages of complex shell structure, inconvenient maintenance and incapability of processing leaked materials. The material is the steel sheet, and the quality is heavier, leads to transport, installation, dismantlement inconvenient, needs a large amount of manpowers or supplementary equipment of lifting by crane. Because the rigidity of steel material exists, the installation butt joint is inconvenient, and the butt joint rectification appears easily during the installation. Meanwhile, the follow-up observation and overhaul are very inconvenient, and the assembly of the protective cover needs to be completely removed in the case of large overhaul such as replacing the adhesive tape, so that the time and labor are very consumed.

3) The whole sealed back of equipment, the dust is at the inside settlement of casing to installation ground, spills the material and also can not handle, and long-pending long-term accumulation, the dust needs a large amount of manual works to regularly clear up. The use of the color steel plate cover can lead to poor protection and partial sealing.

4) Meanwhile, the overall sealing cover shell is used for preventing transportation deformation and use deformation, the steel plate of the sealing shell is generally 1-2mm in thickness, a fixed frame needs to be supported, the weight is about 10 kg/square meter, the material cost reaches 45 yuan/square meter according to the current price of 4.5 yuan/kg of steel, and the manufacturing cost is high.
