[0005] In order to reduce the dust in the water tank and reduce the influence of dust residue on the subsequent dust removal effect, this application provides a blasting dust removal device.

[0006] The blasting dust removal device provided by this application adopts the following technical solutions:

[0007] A blasting dust removal device, comprising a water tank, a dust suction component, and an air outlet pipe. The air outlet pipe is communicated with the water tank. The water tank is used for storing filtering liquid. The dust suction component is used for sucking the gas with dust into the filtering liquid. The water tank is communicated with a sewage discharge pipe. A moving ring is slidably connected in the water tank. The moving ring is horizontally arranged. The water tank is connected with a moving component. The moving component is used for driving the moving ring to be slidably connected to the water tank in the vertical direction. The moving ring is further connected with a plurality of spray heads. The spray heads are communicated with a water delivery pipe. The other end of the water delivery pipe is communicated with a water supply source. The spray heads are used for spraying water on the inner wall of the water tank.

[0008] By adopting the above technical solution, during use, the dust suction component sucks the gas into the filtering liquid in the water tank. The filtering liquid adsorbs the dust in the water tank, thereby reducing the dust in the gas. The gas passing through the filtering liquid is discharged through the air outlet pipe. And during use, the spray heads are arranged above the liquid level of the filtering liquid. After use, the filtering liquid is discharged through the sewage discharge pipe. When the filtering liquid is discharged, the moving component drives the moving ring to move downward in the vertical direction. At the same time, the spray heads spray water towards the inner wall of the water tank. Under the scouring action of the water flow, the dust attached to the inner wall of the water tank follows the water flow and is discharged from the water tank, thereby reducing the dust in the water tank and reducing the influence of the residual dust in the water tank on the dust removal effect.

[0009] Optionally, the moving component includes a rack, a gear, and a first motor. The length direction of the rack is consistent with the vertical direction. The bottom end of the rack is connected to the moving ring. The gear is arranged in the water tank. The gear meshes with the rack. The first motor is connected to the water tank. The output shaft of the first motor is connected to the gear.

[0010] By adopting the above technical solution, when cleaning the inner wall of the water tank, the first motor drives the gear to rotate, thereby driving the rack and the moving ring to move in the vertical direction, and further driving the spray heads to move. During the movement of the moving ring, the spray heads spray water on the inner wall of the water tank. Under the scouring action of the water flow, the dust attached to the inner wall of the water tank follows the water flow and is discharged from the water tank, thereby reducing the dust in the water tank.

[0011] Optionally, the moving ring is further connected with a scraping ring. The scraping ring is horizontally arranged. The scraping ring is in contact with the inner wall of the water tank. The water outlet of the spray head is arranged towards the scraping ring.

[0012] By adopting the above technical solution, when cleaning the inner wall of the water tank, the moving component drives the moving ring to move downward in the vertical direction. The scraping ring follows the moving ring to move, so that the scraping ring pushes the dust on the inner wall of the water tank downward. When the scraping ring moves to the bottom of the water tank, the spray heads spray water on the scraping ring. The dust attached to the surface of the scraping ring is washed away from the scraping ring under the scouring action of the water flow, and the dust follows the water flow and is discharged from the water tank, thereby reducing the consumption of water during the process of cleaning the inner wall of the water tank and improving the cleaning effect.

[0013] Optionally, a collection box is connected to the bottom of the water tank. The length direction of the collection box is the same as the width direction of the water tank. A movable box is connected inside the collection box. The length direction of the movable box is the same as the width direction of the water tank. One end of the collection box in its length direction is provided with a connection port for the movable box to pass through. The movable box is slidably connected in the connection port and inside the collection box along its length direction. The movable box is detachably connected to the collection box along its length direction and near one end of the connection port. The sewage pipe is communicated with the movable box, and a first filter screen is connected inside the sewage pipe. The first filter screen is arranged at one end of the sewage pipe close to the movable box.

[0014] By adopting the above technical solution, when cleaning the inner wall of the water tank, the nozzle sprays water on the scraping ring. Under the scouring action of the water flow, the dust follows the water flow into the movable box, and the water flow is discharged from the movable box through the sewage pipe. The dust is collected in the movable box. After the cleaning is completed, the movable box is detached from the collection box, and the movable box is pulled along the length direction of the collection box, so that the movable box is far away from the collection box, which is convenient for the reference personnel to centrally process the dust and reduce the dust in the water, and is convenient for the recycling of water.

[0015] Optionally, guide plates are connected to the inner walls on both sides of the water tank along its width direction. The length direction of the guide plates is the same as the width direction of the water tank. The two ends of the guide plates in their length direction are respectively connected to the inner walls on both sides of the water tank along the width of the water tank. The two guide plates are arranged at intervals in sequence along the length direction of the water tank. The collection box is arranged between the two guide plates. One side of the guide plate along its width direction is connected to the inner wall on one side of the water tank along the width direction of the water tank, and the other side of the guide plate is connected to the top of the collection box.

[0016] By adopting the above technical solution, when the nozzle sprays water on the scraping ring, the water flow scours the dust on the surface of the scraping ring. The dust follows the water flow and flows to the surface of the guide plate. Under the guiding action of the guide plate, the water flow carries the dust and flows into the movable box, so as to reduce the dust accumulation on the inner wall of the bottom of the water tank, and the guide plate is inclined, which accelerates the water flow and the dust to enter the movable box.

[0017] Optionally, a mounting plate is connected to one end of the movable box along its length direction. The mounting plate is connected to the end of the movable box close to the connection port. The mounting plate contacts the collection box. A sealing layer is connected to one side of the mounting plate close to the collection box. The mounting plate and the collection box are detachably connected by bolts.

[0018] By adopting the above technical solution, when there is dust in the movable box, the mounting plate is detached from the collection box, and the movable box is pulled along the length direction of the movable box, so that the movable box is far away from the collection box, which is convenient for the treatment of dust.

[0019] Optionally, the water tank includes a first box body and a second box body. The first box body and the second box body are arranged in sequence along the vertical direction. The first box body is communicated with the second box body. Both the first box body and the second box body are provided with openings, and the openings of the first box body and the second box body are arranged opposite to each other. The dust suction assembly is connected to the first box body, the moving assembly is connected to the first box body, the first box body and the second box body are detachably connected, and the scraping ring is detachably connected to the moving ring.

[0020] By adopting the above technical solution, after long-term use, the scraping ring is prone to wear, and the cleaning effect of the worn scraping ring on the inner wall of the water tank is reduced. The first box body is detached from the second box body, the scraping ring is detached from the moving ring, and a new scraping ring is replaced, so as to improve the cleaning effect of the scraping ring on the inner wall of the water tank.

[0021] Optionally, the scraping ring is connected with a support block. The support block is connected to one side of the scraping ring along the length direction of the water tank. The support block is connected to the inner ring of the moving ring. An installation groove is formed in the inner wall of one side of the moving ring along the length direction of the water tank. The length direction of the installation groove is consistent with the length direction of the water tank. A first spring and a locking block are connected in the installation groove. The length direction of the first spring is consistent with the length direction of the water tank. One end of the first spring is connected to the inner wall of the installation groove along its length direction, and the other end of the first spring is connected to the locking block. The locking block is slidably connected to the installation groove along the length direction of the water tank. The support block is provided with a locking hole for the locking block to pass through.

[0022] By adopting the above technical solution, when installing the scraping ring, the scraping ring and the support block move along the vertical direction. The support block contacts the inner ring of the moving ring, and the support block pushes the locking block to be embedded in the installation groove. The locking block squeezes the first spring, causing the first spring to deform. When the locking block approaches the locking hole, the first spring restores its shape, and the first spring pushes the locking block to pass through the locking hole, so that the support block is stably connected to the moving ring.

The gas passing through the filtering liquid is discharged through the air outlet pipe. During use, the scraping ring is arranged above the liquid level of the filtering liquid. After use, the filtering liquid is discharged through the sewage discharge pipe. When the filtering liquid is discharged, the moving assembly drives the moving ring to move downward along the vertical direction. At the same time, the nozzle sprays water towards the inner wall of the water tank. Under the scouring action of the water flow, the dust attached to the inner wall of the water tank is discharged from the water tank along with the water flow, thereby reducing the dust in the water tank and reducing the influence of the residual dust in the water tank on the dust removal effect;

[0025] 2. When cleaning the inner wall of the water tank, the moving component drives the moving ring to move downward in the vertical direction, and the scraping ring follows the moving ring to move, so that the scraping ring pushes the dust on the inner wall of the water tank downward. When the scraping ring moves to the bottom of the water tank, the nozzle sprays water on the scraping ring, and the dust attached to the surface of the scraping ring is washed away by the water flow and moves away from the scraping ring, and the dust is discharged from the water tank along with the water flow, thereby reducing the consumption of water during the process of cleaning the inner wall of the water tank and improving the cleaning effect;

[0026] 3. When the nozzle sprays water on the scraping ring, the water flow washes the dust on the surface of the scraping ring. The dust flows along with the water flow to the surface of the guiding plate. Under the guiding action of the guiding plate, the water flow carries the dust and flows into the moving box, thereby reducing the accumulation of dust on the inner wall of the bottom of the water tank.
