First, the motor current suddenly increases, second, the energy consumption increases, third, the dust removal work stops due to the automatic protection of the motor; fourth, it is caused by micro dust If the particle size is too small, even the bag in the bag pulse dust collector cannot completely block the dust removal, so it will inevitably be discharged from the bag pulse dust collector, causing the most harmful air pollution.

Utility model content

Design purpose: to avoid the deficiencies in the background technology, to design a water curtain dust removal device that can not only effectively capture micro dust, but also quickly separate dust larger than micro dust from the water curtain dust removal device.

Design scheme: In order to achieve the above design purpose. 1. In the water curtain dedusting device, the design of the dust discharge pipe and the critical dust suction port on the upper part of the dust discharge pipe is one of the technical characteristics of the utility model. The purpose of this design is: when using the air outlet pressure of the cyclone dust removal device to push the powder containing micro-dust and larger than the micro-dust to the critical dust suction port of the micro-dust, because the dust discharge pipe has a chimney effect, the dust in the dust discharge pipe The air pressure is far greater than the air pressure outside the dust discharge pipe, so it can quickly rise the micro dust in the dust discharge pipe under the action of the chimney effect and separate it from the dust larger than its weight, and enter the water curtain dust removal device, making the weight larger than the micro dust The dust is sucked away by the negative pressure fluid generated by the pulse bag dust removal device. Since the dust larger than the micro dust contains almost no micro dust and belongs to the particle structure, it is not easy to adhere to the pulse bag, so it will not cause the pulse bag. The filter saturation failure will not cause a sudden increase in the motor current, nor will it cause a large energy consumption, which ensures the normal operation of the pulse bag dust removal device. 2. The design that one or more circles of water spray pipe circles are distributed on the inner wall of the water curtain dust removal cover is two of the technical characterictics of the present utility model. The purpose of this design is: since there are a plurality of micro spray holes on the surface of one or more circles of water spray pipes, the water mist sprayed from the micro spray holes intersects to form a water curtain. When it is submerged by the water curtain, the turbid fluid falls into the drain tank under the water curtain dust cover and is drained through the drain holes and drain pipes in the drain tank, thus solving the problem of micro dust that has been difficult to solve in this field. Capture puzzles.

Technical solution: a water curtain dust removal device, the upper part of the fluid delivery pipe in the water curtain dust removal device is located in the water curtain dust removal cover and the outlet of the fluid delivery pipe is directly facing the cover of the water curtain dust removal cover, and the water spraying pipes are distributed in one or more circles On the inner wall of the water curtain dust removal cover and communicated with the water inlet pipe, the drain tank is inclined and fixed on the fluid delivery pipe and is located below the water curtain dust removal cover, and the drain hole in the liquid drain tank communicates with the drain pipe.

Compared with the background technology, the utility model combines the water curtain dust collector with the pulse bag dust collector, one is to fundamentally solve the sudden increase of the motor current and the energy loss caused by the pulse bag dust collector being easily blocked by the adhesion of micro dust. The second is to avoid the stop of the dust removal work caused by the automatic protection of the motor in the pulse bag filter device due to the sudden increase in current, which greatly improves the dust removal efficiency of the pulse bag filter device; the third is not only to fundamentally solve the problem of micro The dust particle size is too small to be discharged from the bag pulse dust removal device, and the fine dust dust filler urgently needed by high-strength concrete has been obtained.

A water curtain dust removal device, the upper part of the fluid delivery pipe 25 in the water curtain dust removal device 2 is located in the water curtain dust removal cover 21 and the outlet of the fluid delivery pipe 25 is directly facing the water curtain dust removal cover 21 cover, and one or more turns of the water spray pipe Ring 22 is distributed on the inner wall of water curtain dust removal cover 21 and is communicated with water inlet pipe 24. Drainage tank 23 is inclined and fixed on fluid delivery pipe 25 and is positioned at water curtain dust removal cover 21 below. The liquid pipe 26 communicates. The upper part of the dust discharge channel in the water curtain dedusting device 2 has a critical dust suction port 5 for fine dust. The height of the critical suction port 5 for fine dust is set according to the suction force of the pulse bag filter 1 inlet. When the suction force is high, the critical suction port 5 for fine dust is high; when the suction force is small, the critical suction port 5 for fine dust is low. Refer to accompanying drawings 2 and 3. A triple dedusting system for dry gravel sand making consisting of a water curtain dedusting device. A fine dust water curtain dedusting device 2 is provided between the cyclone dedusting device 3 and the pulse bag dedusting device 1 . The dust outlet of the cyclone dust removal device 3 is connected with the inlet of the water curtain dust removal device 2 through the dust discharge pipe, and the critical dust suction port 5 of the water curtain dust removal device 2 is connected with the inlet 1 of the pulse bag dust removal device. The dust critical suction port 5 in the water curtain dedusting device 2 is higher than the inlet of the pulse bag dedusting device 1 . The height of the critical dust suction port 5 of the water curtain dust removal device 2 is set according to the suction force of the inlet of the pulse bag dust removal device 1. When the suction force is large, the critical dust suction port 5 of the fine dust is high; Dust port 5 is low. The upper part of the fluid delivery pipe 25 in the water curtain dust removal device 2 is located in the water curtain dust removal cover 21 and the outlet of the fluid delivery pipe 25 is directly facing the water curtain dust removal cover 21 cover. The inner wall of the cover 21 is communicated with the water inlet pipe 24. The drain tank 23 is inclined and fixed on the fluid delivery pipe 25 and is positioned below the water curtain dust removal cover 21. The drain hole in the drain tank 23 communicates with the drain pipe 26. Because in the manufacturing process of machine-made stones and machine-made sand, a large amount of stone micro-dust is inevitably produced. The stone micro-dust floats in the fluid, which cannot be removed by the cyclone dust collector, and causes the stone micro-dust to quickly accumulate and accumulate. Adhesion in the pulse bag dust collector and it is not easy to remove, as a result, not only the sudden increase of the working current of the pulse bag dust collector motor, the increase of energy consumption, but also the loss of the dust removal function of the pulse bag dust collector, resulting in the failure of dust removal. The utility model can solve this difficult problem by setting a fine dust water curtain dedusting device between the cyclone dedusting device and the pulse bag dedusting device. Because the micro-dust water curtain dedusting device of the utility model has not only reserved a fluid channel for the micro-dust of the stone in terms of structural design, but also provided a water curtain at the end of the fluid channel. When returning to the channel, it is submerged by the water curtain to form a mixed fluid that flows into the drain tank under the water curtain dust cover and is discharged to the sedimentation tank through the drain holes and drain pipes in the drain tank to obtain ultra-fine high-strength concrete ingredients .
