Dust removal and noise reduction pulping equipment and control method thereof

Abstract

The invention discloses dust removal and noise reduction pulping equipment, comprising a barrel and a cover plate, wherein a downward conical spacer plate is arranged in the middle of the barrel; an inner cavity of the barrel is divided into an upper stirring bin and a lower storage bin; a discharge outlet is formed in the middle of the conical spacer plate; a top plate is arranged at the upper part of the upper stirring bin; a bottom plate is arranged at the bottom of the lower storage bin; the interior of the top plate has a hollow structure, and a drive motor and a metering pump are installed in the hollow structure of the top plate; the interior of the bottom plate has a hollow structure, and a pulp outlet pump is installed in the hollow structure of the bottom plate; a stirring assembly comprises a stirring shaft, stirring blades and a spray pipe; a high-strength hollow steel pipe is adopted at the upper part of the stirring shaft, and the spray pipe is connected with the high-strength hollow steel pipe. Furthermore, the invention also discloses a control method of the pulping equipment; the dust removal and noise reduction pulping equipment has the beneficial effects of beingenvironmentally friendly, uniform in pulping, simple in structure, convenient to operate, and the like.

Description

technical field [0001] The invention relates to the technical field of coal mine grouting equipment, in particular to a dust-removing and noise-reducing slurry-forming equipment and a control method thereof. Background technique [0002] At present, the treatment of coal mined-out area or underground karst cave mainly adopts the grouting method, and the grouting material is mainly cement fly ash, and there is also cement loess. On site, the grouting material needs to be stirred with a slurry to form a slurry, and injected into the goaf or underground cavern through the grouting device. [0003] Cement and fly ash are both powdery materials, and the existing grouting slurry mixing device is prone to dust pollution during feeding and mixing. In order to remove dust, the construction site usually needs to install additional dust collectors, which increases the construction cost. [0004] In addition, most of the existing slurrying equipment does not use any sound insulation d...

AI Technical Summary

Problems solved by technology

[0003] Cement and fly ash are powdery materials, and the existing grouting slurry mixing device is prone to dust pollution during feeding and mixing

In order to remove dust, the construction site usually needs to set up additional dust collectors, which increases the construction cost

[0004] In addition, most of the existing slurrying equipment does not use any sound insulation device. The collision and friction between the stirring shaft and the grouting material and mechanical vibration will generate a lot of noise, which will affect the health of the construction workers. If it is close to the residential area, it will also affect the daily life of the residents.

Of course, in recent years, as the country vigorously advocates environmental protection, sound-proof cover-type pulping equipment has appeared on the market, that is, the entire pulp-making equipment is covered with a sound-proof cover, which reduces noise pollution to a certain extent, but the effect is limited, and the installation is relatively Troublesome, affecting the operation of workers, it is difficult to ensure the quality of pulp

[0005] In addition, for continuous grouting, the existing slurrying equipment is mostly grouting while stirring, and the powdery material is easy to agglomerate. If the stirring is not sufficient, it is difficult to ensure uniform slurry, which will affect the quality of slurry.
