Description

Technical Field

[0001] The utility model relates to the technical field of dust removal in fracturing quartz sand processing, in particular to a dust remover for fracturing quartz sand processing which is easy to install. Background Art

[0002] Fracturing sand is a kind of high-purity quartz sand, which is processed through a pure physical, zero-pollution production process of raw ore → pre-screening → scrubbing → desliming → coarse-grained classification → fine-grained classification → magnetic separation → concentration → dewatering screen → dryer → screening → finished product. It has super high pressure resistance and extremely high roundness. It is mainly used in the oil and gas industry. When energy companies exploit oil and natural gas, they inject fracturing fluid into oil and gas reservoirs through high-pressure water pumps to obtain oil and gas resources. At present, the fracturing sands on the market mainly include: quartz sand, metal aluminum balls, glass beads, steel balls, ceramsite sand, etc., among which quartz sand accounts for 50% of the market share.

[0003] In the process of fracturing quartz sand processing and screening, quartz sand dust will be scattered in both dewatering and screening, and the prior art often uses bag dust collectors to remove dust from fracturing quartz sand processing. For example, Chinese Patent Publication No. CN219897418U discloses a bag dust collector for fracturing quartz sand production that is easy to install. The dust removal device is extremely easy to install and remove through the modular design of the embedded support mechanism. The stable embedding of the telescopic clamp column and the telescopic lock buckle can offset the additional vibration generated during the high-power operation of the dust collector. The trapezoidal support foot can also provide sufficiently stable support for the overall equipment. The connecting clamp can constrain the dust collector body firmly, and the dust collector body and the dust accumulation funnel can be quickly disassembled, separated and installed.

[0004] However, the above-mentioned dust accumulation funnel and pulse jet cleaning pipeline are difficult to remove the fracturing quartz sand during the screening process, and the effect is poor. It is easy to block the pipe mouth and the screen and do not meet the turbidity standard of the fracturing proppant. Utility Model Content

[0005] The utility model provides a dust collector for processing fracturing quartz sand which is easy to install, so as to solve the problems raised in the above-mentioned background technology.

[0006] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0008] A further improvement of the technical solution of the utility model lies in that: both ends of the screening filter screen plate are fixedly connected to the dust removal box, both ends of the grafting cross plate are fixedly connected to the dust removal box, the power rod is located in the middle of the grafting cross plate, the power rod is rotatably connected to the grafting cross plate, the power rod is fixedly connected to the installation drive member, the installation drive member is fixedly connected to the vibrating screen wheel through the installation port and the fastener, the power rod is rotated by a motor or manually, and the power rod drives the installation drive member to rotate after the rotation, and then the vibrating screen wheel on the installation drive member starts to rotate. As shown in the figure, the vibrating screen wheel is an irregular semicircle, and the impact part of the vibrating screen wheel continuously impacts the screening filter screen plate during the rotation process. Although the two ends of the screening filter screen plate are fixedly connected to the dust removal box, the filtering part of the screening filter screen plate is not completely rigid, and it will still undergo a certain deformation when it is impacted, and then the quartz sand dust in the mesh is impacted, so that large particles of quartz sand dust fly in the dust removal box.

[0009] A further improvement of the technical solution of the utility model is that telescopic rods are provided at both ends of the grafting horizontal plate, the other end of the top telescopic rod is fixedly connected to the screening filter plate, and the other end of the bottom telescopic rod is fixedly connected to the dust removal box, and reset springs are provided on the two telescopic rods.

[0010] A further improvement of the technical solution of the utility model is that the dust removal spray unit includes a water tank, a water pipe is provided on one side of the water tank, a rotating elbow is provided at the other end of the water pipe, a water spray pipe is provided at the other end of the rotating elbow, and a rotating joint is provided at the connection between the water spray pipe and the rotating elbow.

[0011] A further improvement of the technical solution of the utility model is that: the water storage tank is fixedly installed on the top of the dust removal box body, the water storage tank is fixedly connected to the water pipe, and a seal is provided at the connection between the water pipe and the water storage tank, the other end of the water pipe is fixedly connected to the rotating elbow, the rotating elbow is movably connected to the water spray pipe through a rotating joint, and the rotating joint is fixedly installed on the water spray pipe.

[0012] A further improvement of the technical solution of the utility model is that: a transmission gear 1 is provided on the rotary joint, a transmission gear 2 is provided on one side of the transmission gear 1, and the transmission gear 2 is located on a rotating shaft.

After the rotating shaft rotates, the transmission gear two rotates. Because of the kneading, the transmission gear one rotates, and then because the rotating elbow is movably connected with the water spray pipe, the water spray pipe drives the dust removal nozzle part to rotate in the installation cavity and spray water, and then collides with the quartz sand dust in the above-mentioned middle mesh, so that large particles of quartz sand dust fly in the dust removal box. At this time, the water spray can quickly process the quartz sand dust, and the quartz sand dust flying after the vibration will not condense when it encounters water, thereby avoiding the situation where condensation is generated by spraying water directly onto the filter.

[0014] Due to the adoption of the above technical solution, the utility model has achieved the following technical progress compared with the prior art:

[0015] 1. The utility model provides a dust collector for processing quartz sand for fracturing, which is easy to install. By setting a dredging and screening unit, the quartz sand dust in the filter holes of the filter can be quickly vibrated into the processing box before water is sprayed, and the vibration amplitude of the filter can be adjusted by rotating the fasteners to replace the vibrating screen wheel, thereby avoiding the quartz sand dust or larger quartz sand particles from sticking to the filter holes, meeting the turbidity standard of the proppant for fracturing, and the production workshop is pollution-free, meeting the occupational health and environmental protection requirements.

[0016] 2. The utility model provides a dust collector for fracturing quartz sand processing that is easy to install. By arranging a dust removal spraying unit, the overall device can perform a rotational spraying operation in a processing box after the quartz sand dust is impacted and flown, thereby greatly improving the dust reduction efficiency and avoiding the situation in which the quartz sand dust is condensed due to direct spraying on the filter.

[0026] Both ends of the screening filter screen plate 201 are fixedly connected to the dust removal box body 1, and both ends of the grafting cross plate 202 are fixedly connected to the dust removal box body 1. The power rod 203 is located in the middle of the grafting cross plate 202, and the power rod 203 is rotatably connected to the grafting cross plate 202. The power rod 203 is fixedly connected to the installation drive member 204, and the installation drive member 204 is fixedly connected to the vibrating screen wheel 205 through the installation port and fasteners.

As shown in the figure, the vibrating screen wheel 205 is an irregular semicircle. The impact part of the vibrating screen wheel 205 continuously impacts the screening filter plate 201 during the rotation process. Although the two ends of the screening filter plate 201 are fixedly connected to the dust removal box 1, the filtering part of the screening filter plate 201 is not completely rigid. When it is impacted, it will still undergo a certain deformation, and then impact the quartz sand dust in the mesh, so that large particles of quartz sand dust fly in the dust removal box 1.
