Description

Dust fall band conveyer

Technical Field

The utility model relates to a belt feeder field, concretely relates to band conveyer with dust fall function.

Background

The belt conveyor is commonly used in a construction waste crushing treatment system as a conveying device for raw materials and finished products, and the construction waste crushing treatment has higher requirements on the particle size of the finished products, so that the particle size of the crushed materials is small, dust is easily generated, adverse effects on the environment and air are caused, and the improvement on the aspect of dust falling effect of the belt conveyor becomes the trend of research in the industry.

However, most of the existing dust-falling belt conveyors focus on dust emission in the process of conveying materials by the belt conveyors, but because material piling or material loading into a vehicle is needed, the discharge end of the belt conveyor for conveying finished products after crushing treatment of construction waste is often set to be very high, and even if dust-falling treatment is carried out in the conveying process, a large amount of dust emission is still easily generated after the materials are separated from the belt conveyor, so that the stacking and loading of the materials are not facilitated; in addition, the dust falling treatment in the material transportation process can also cause water drops remained on the surface of the belt, thereby causing adverse effect on material transportation.

SUMMERY OF THE UTILITY MODEL

The to-be-solved technical problem of the utility model is to overcome the not enough of prior art existence, provide a dust fall band conveyer, this dust fall band conveyer can effectively reduce the raise dust that the material produced after breaking away from the belt, the stacking and the loading of the material of being convenient for.

In order to solve the technical problem, the utility model discloses a following technical scheme:

the utility model provides a dust fall band conveyer, includes band conveyer, water supply pipe and dust fall subassembly, water supply pipe one end intercommunication water source, the other end is linked together with the dust fall subassembly, the dust fall subassembly includes the dust fall pipeline and sets up one or more dust fall nozzles on the dust fall pipeline, band conveyer's discharge end sets up the position that is showing to be higher than ejection of compact blanking point, the dust fall subassembly sets up the region of process during band conveyer's discharge end below and ejection of compact blanking. Above-mentioned technical scheme's design lies in, the band conveyer that has the dust fall function now sprays the dust fall mostly and sets up the transport section at band conveyer, with the raise dust problem of reduction in the material transportation, but the finished product particle diameter behind the building rubbish broken handle is less, partial light material in addition, when using band conveyer windrow or loading, above-mentioned finished product falls from the band conveyer discharge end that sets up at the eminence, very easily cause serious raise dust, the existing device then is difficult to avoid this defect, it is not significant to lead to the dust fall effect, remaining moisture on the dust fall sprays the back belt still easily causes adverse effect to the transport of material. The utility model discloses then with its setting of dust fall subassembly below band conveyer's discharge end, spray the dust fall through the dust fall subassembly after making the material break away from the belt, dust suppression effect is excellent, can show the raise dust problem that reduces windrow or loading, still can not leave the water droplet on the belt, influences the material transportation.

As a further improvement of the above technical solution:

the dust settling pipeline is enclosed into a closed or unsealed ring shape by a plurality of sections of sub-pipelines.

The annular inner area defined by the dust fall pipeline is an area passed by the belt conveyor during discharging and blanking. With the closed or unclosed annular structure of dust fall pipeline design for possessing a plurality of dust fall nozzles, can make the material break away from and pass this annular structure behind the belt, spray the dust fall through the dust fall nozzle that sets up to the material of whereabouts and the raise dust of production on the dead angle ground, this kind of structure can show the effect that promotes the dust fall that sprays.

The dust fall nozzle faces an annular inner area surrounded by the dust fall pipeline.

A plurality of dust fall nozzles in the dust fall subassembly are radial towards the annular inner region that the dust fall pipeline encloses. The arrangement mode of the dust falling nozzles is designed to be radial, the covering angle of the dust falling nozzles to the raised dust generated by falling materials can be increased, so that spraying at dead angles is avoided, the dust falling effect can be greatly increased, and the phenomenon that the dust falling caused by the weather (wind power) problem is unstable can be avoided.

A plurality of dust fall nozzles in the dust fall subassembly are different elevation angles orientation in the vertical direction the annular inner region that the dust fall pipeline encloses. The orientation of adjacent nozzle is crisscross to be set up in the dust fall subassembly, arranges into different elevations, can enlarge the injection coverage area of all nozzles, further promotes the dust fall scope of dust fall subassembly to improve dust fall band conveyer's dust fall and carry the effect.

Band conveyer below is provided with a plurality of dust fall subassemblies along different height positions, just the annular inner region that the dust fall pipeline that all passes every dust fall subassembly encloses during band conveyer's ejection of compact blanking. According to the particle size of the conveyed materials, a plurality of dust fall assemblies consistent in the vertical direction can be arranged below the discharge end of the belt conveyor, so that the materials pass through all the dust fall assemblies in the falling process, and the dust fall conveying effect of the belt conveyor can be improved when the particle size of the materials is too small and the dust rise scale is large.

Dust fall pipeline encloses into unclosed octagon annular structure among the dust fall subassembly, constitutes all be provided with a dust fall nozzle on every section sub-pipeline of octagon. Through a plurality of tests and optimization of the inventor, the fact that the dust settling assembly is arranged to be an unclosed octagon, and one dust settling nozzle is arranged on each edge of the octagon can improve the dust settling effect of the dust settling assembly to the maximum extent, and the cost of the device is controlled within an acceptable range.

The dust fall nozzle is a fan-shaped or solid conical nozzle. Compared with a straight nozzle, the fan-shaped or solid conical nozzle can further enlarge the spraying range of the dustfall nozzle and improve the dustfall conveying effect of the dustfall belt conveyor.

The dust fall subassembly is connected through a flexible subassembly on the band conveyer, flexible subassembly is flexible along the vertical direction. The flexible subassembly can guarantee the removal of dust fall subassembly on the vertical direction for the user can be according to the position of the most serious regional regulation dust fall subassembly of transported substance particle size, raise dust degree and raise dust, thereby improves the dust fall effect.

Compared with the prior art, the utility model has the advantages of: the utility model discloses a dust fall band conveyer can encircle the raise dust that produces after breaking away from the belt to the transported substance material and spray the dust fall, and the dust fall effect is excellent, can show the raise dust problem that reduces windrow or loading, still can not leave the water droplet on the belt, the material transport of being convenient for, stack and load.
