Description
Technical Field
The utility model relates to a proppant screening dust removal technical field, concretely relates to low density high strength andalusite dust collector for fracturing proppant.
Background
The proppant is required to be screened after being formed, so that the proppant is graded according to the particle size, when the proppant is screened, a drum-type screening machine is the most common screening machine, and dust is often attached to the surface of the proppant, so that the scattered dust pollutes the surrounding environment in the rotating process of a screen, and the dust needs to be recycled.
Chinese patent with publication number CN201880679U discloses a "dust removal screening machine for production of oilfield fracturing propping agent", which comprises a frame and a cylindrical screen rotatably arranged on the frame, wherein a dust-shielding cover matched with the frame is covered outside the screen, a dust removal pipeline for discharging dust is communicated with the upper end of the dust-shielding cover, and an outlet of the dust removal pipeline is connected with a dust remover. Although the dust removal screening machine solves the problem of environmental pollution caused by dust, in actual production, the dust collected by the dust collection screening machine contains a part of particles, and researches show that the particles are generated by broken proppants or proppants with extremely small particle sizes, and the particles can influence the reuse of the dust, because the particles can have adverse effects on the granulating process of the proppants.
SUMMERY OF THE UTILITY MODEL
In view of this, the present invention aims to provide a dust removing device for a low-density high-strength andalusite fracturing propping agent.
The utility model discloses the technical scheme who adopts does:
the design is a low-density high-strength dust collector for andalusite fracturing propping agent, which comprises a dust hood used for covering and locating a screening machine, the top of the dust hood is communicated with a branch pipeline arranged along the vertical direction, the top of the branch pipeline is communicated with a main pipeline arranged along the horizontal direction, the other end of the main pipeline is connected with a bag type dust collector, a filter screen is arranged in the main pipeline, and the air inlet side of the filter screen is provided with a discharge pipe communicated with the main pipeline.
Preferably, the filter screen is obliquely arranged and is positioned right above the discharge pipe.
Preferably, the main pipeline is communicated with an installation pipe, the installation pipe is arranged along the direction perpendicular to the filter screen, a driving motor is arranged at the tail end of the installation pipe, a power output shaft of the driving motor is in transmission connection with a rotating shaft in the installation pipe, and the other end of the rotating shaft penetrates through the filter screen and is connected with the cleaning brush.
Preferably, a purge air pipe is arranged in the dust collection cover, and a plurality of purge air nozzles are linearly distributed on the purge air pipe.
Compared with the prior art, the utility model has the advantages that:
1. the utility model discloses a mode of two-stage filtration, categorised recovery cuts apart dust and particulate matter and retrieves respectively for the dust of collecting can direct reutilization, has reduced the waste of raw materials, has reduced manufacturing cost.
2. The utility model discloses the air inlet side at the filter screen is equipped with the brush cleaner to drive the brush cleaner through the axis of rotation and clean the filter screen, can effectively reduce the probability of filter screen jam.
