Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of dust spraying, and particularly relates to a dust spraying system for a sand dust environment of a stockyard. BACKGROUND

[0002] During the process of stacking materials, a large amount of suspended particulate matter is generated due to mechanical disturbance, wind erosion and material volatilization, and the suspended particulate matter will float in the air and move with the air, which not only harms the respiratory tract and lungs of the workers at the stockyard, but also affects the environment around the stockyard and causes air pollution in the whole city.

[0003] At present, the dust reduction treatment of the stockyard is mainly by spraying water or laying dustproof nets. For the former, the stockyard is usually surrounded by a fence (the mainstream spraying system is usually a steel or concrete fence structure), and then the spraying head is placed above the fence. In actual application, due to the large height of the stockyard, the height of the fence is set to be very high in order to reduce the diffusion of dust as much as possible. For example, the height of the fence of some stockyards is high, and the prior art (patent publication No. CN216949823U discloses a municipal reconstruction dustproof spraying fence) sets a plurality of spraying heads on the fence, and the spraying heads arranged above the fence are all directly directed towards the inside of the stockyard, so that the water mist is easily blown away by the gas as soon as it is sprayed, and the dispersion area of the water mist is basically near the fence, which cannot effectively reduce the dust of the suspended particulate matter far away from the fence, and the dust reduction effect is general. At the same time, the sprayed water mist is affected to a certain extent, and small particle size water droplets are easily evaporated, and large particle size water droplets are prematurely settled, so that the water mist cannot be well mixed with the suspended particulate matter, and the gravity of the suspended particulate matter is increased to sink. SUMMARY

[0004] The present application aims to provide a dust spraying system for a sand dust environment of a stockyard to solve the problems in the prior art.

[0005] To achieve the above-mentioned purpose, the present application provides the following technical scheme:

[0006] A dust spraying system for a sand dust environment of a stockyard, comprising a plurality of fences, the fence is composed of a bottom plate and a top plate, the bottom plate and the top plate are supported by a pipe, a plurality of spraying openings are arranged on the side of the top plate away from the bottom plate, the spraying openings are equidistantly arranged along the side edge of the top plate, a pipe is arranged in the top plate, and the spraying openings are communicated with the pipe in the top plate.

[0007] Preferably, the bottom plate is provided with a water pump, the water pump is connected to the pipeline between the bottom plate and the top plate through the water delivery pipe, the side of the top plate away from the bottom plate is further provided with a hemispherical plate, the top of the hemispherical plate is provided with an extension plate, and the arc center of the hemispherical plate is located on the side of the extension plate close to the spray port.

[0008] Preferably, the spray direction of the spray port is consistent with the tangent direction of the hemispherical plate, and the axis of the spray port is perpendicular to the axis of the extension plate.

[0009] The water pump draws water from an external water source, delivers it to the pipeline between the bottom plate and the top plate through the water delivery pipe, and then delivers it to the spray port through the pipeline. After the water is atomized in the spray port, it is sprayed out. The water mist is sprayed out towards the side close to the hemispherical plate. The water mist moves along the side edge of the hemispherical plate towards the side close to the extension plate, and moves along the extension plate towards the center of the yard. Since the spray direction of the spray port is consistent with the tangent direction of the hemispherical plate, and the axis of the spray port is perpendicular to the axis of the extension plate, the direction of the water mist when it is sprayed out is opposite to the direction of the water mist in the yard.

[0010] Since the water mist is moving along the hemispherical plate and the extension plate at this time, the flow rate of the water mist is at the fastest state, and the space pressure between the hemispherical plate and the extension plate is in a low pressure area. At this time, the air flow rate close to the fence on the side of the yard is weak, and the space pressure is high. Therefore, the air in the yard will move under the action of air pressure, and the air will move towards the side close to the fence. Therefore, a circulation will be formed between the yard, the top plate and the extension plate. However, the water mist is output along the extension plate, so that when the water mist moves towards the side close to the center of the yard, it will also drive the surrounding air to move, thereby forming a layer of circulation.

[0011] When several symmetrically arranged fences jointly spray water mist, the air in the center of the yard will move under the action of air pressure, and the air will move from the center of the yard to the edge of the yard. When the air in the center of the yard moves, the air pressure in the center of the yard is lower than the air pressure directly above the yard. Therefore, the air directly above the yard will flow downward, so that the air directly above the yard flows towards the center of the yard, thereby achieving the effect of suppressing dust in the yard within the range surrounded by the fence by using the air pressure to make the air at the top flow towards the center of the yard, thereby avoiding the overflow of dust to the side outside the fence and causing air pollution.

[0012] Preferably, a fixed stake is arranged between the two fences, the top of the fixed stake is provided with a water sprinkler, the water sprinkler is composed of two groups of rotating pipes, the water sprinkler can rotate in multiple directions through the rotating pipes, and the rotating pipes are driven by a rotating motor.

[0013] When local dust reduction needs to be carried out in the yard, the rotating motor is started through the controller, the rotating motor drives the two rotating pipes to rotate, so that the water gun is rotated to the area to be reduced, finally the pipe in the fixed pile is used to transport water to the water gun, and the water column is sprayed to the local dust reduction area, so that the water in the water column is mixed with the dust in the target area and settles, and the effect of local area dust reduction is achieved.

[0014] Preferably, the top plate is provided with a plurality of mixing grooves away from one side of the hemispherical plate, the mixing grooves are provided with atomizing ports, the atomizing ports are also communicated with the pipes in the top plate, and the spray angle of the atomizing ports is inclined to the side close to the mixing grooves.

[0015] Preferably, the cross section of the mixing groove is trapezoidal, and the distance between the mixing groove away from the top plate is greater than the distance between the mixing groove close to the top plate.

[0016] The water mist sprayed from the spray port restrains the dust in the yard, at this time another part of the external water source is transported to the atomizing port through the pipe and sprayed out of the atomizing port, and since the spray angle of the atomizing port is inclined to the side close to the mixing groove, the water mist sprayed from the atomizing port moves along the mixing groove, from the top of the top plate to the side close to the bottom plate;

[0017] At this time, a layer of circulating flow has been formed in the fence, so that the air in the center of the yard will drive the dust to flow close to the fence, when the mixed air moves to one side of the top plate, since the water mist sprayed from the atomizing port flows along the mixing groove, at this time the flow rate in the mixing groove is greater than the flow rate of the mixed air, and the mixed air is then sucked to the mixing groove, and the cross section of the mixing groove is trapezoidal, so that the mixed air flows from the side of the mixing groove away from the top plate to the side of the mixing groove close to the top plate after moving close to the mixing groove, so that the mixed air is mixed with the water mist in the mixing groove, that is, the attachment of the water mist and the dust is completed, so that the volume of the dust is increased.

[0018] Preferably, the mixing groove is provided with a right-angle groove away from the atomizing port, and the middle part of the right-angle groove is provided with a gap.

[0019] Preferably, the side edge axis of the side of the right-angle groove is in parallel with the axis of the extension plate.

[0020] When the mixed air and the water mist mixed by the mixing groove flow to the right-angle groove, the middle part of the right-angle groove is provided with a gap, and at this time, the water mist and the dust complete the mixing and adhesion, and then the air and the water mist drive the dust to flow along the right-angle groove, when the dust passes through the bending part of the right-angle groove, the weight of the dust increases due to the influence of the water mist, and then the dust is thrown out under the action of the centrifugal force, and the dust is discharged through the gap in the middle part of the right-angle groove, so that the dust falling effect is realized, and due to the fact that the side edge axis of the right-angle groove is parallel to the axis of the extension plate, the end of the right-angle groove is the same as the extension plate, so that the water mist flow direction is guided, and then the air and the water mist flow to the side close to the center of the stockyard through the right-angle groove, and the flow speed of the air in the mixing groove and the right-angle groove is further increased due to the influence of the gap in the groove.

[0021] Through the guidance of the extension plate and the right-angle groove, the water mist forms two flow layers of high and low heights, so that the two layers of water mist flow to the center of the stockyard from the fence, and the air mixed with dust in the stockyard moves in the two flow layers of high and low heights, and forms a circulation in the two flow layers of high and low heights, so that the air in the stockyard is inhibited in the range, dust diffusion is avoided, and the air is driven to flow to the side close to the fence by the air pressure, and the dust falling treatment is completed in the mixing groove, so that the efficiency of the stockyard dust falling is improved.

[0022] The water gun is matched with the water gun to complete the overall dust falling and local dust falling of the stockyard, the dust in the air is flowed to the mixing groove, the water mist is prevented from floating in the air, the mixing with the dust is insufficient, the dust falling effect is affected, the water source consumption is saved, the dust is separated to the side close to the fence, the dust is prevented from falling on the ground, and the dust is prevented from floating in the air after the ground is dried, and the water mist in the low flow layer can also continuously wet the ground.

[0023] Compared with the prior art, the beneficial effects of the present application are:

[0024] 1. Through the guidance of the extension plate and the right-angle groove, the water mist forms two flow layers of high and low heights, so that the two layers of water mist flow to the center of the stockyard from the fence, and the air mixed with dust in the stockyard moves in the two flow layers of high and low heights, and forms a circulation in the two flow layers of high and low heights, so that the air in the stockyard is inhibited in the range, dust diffusion is avoided, and the air is driven to flow to the side close to the fence by the air pressure, and the dust falling treatment is completed in the mixing groove, so that the efficiency of the stockyard dust falling is improved.

[0025] 2. Cooperate with the sprinkler gun to complete the overall and local dust reduction of the yard. By flowing the dust in the air to the mixing tank, it prevents the water mist from floating in the air, resulting in insufficient mixing with the dust, affecting the dust reduction effect. On this basis, it saves a certain amount of water consumption and separates the dust to the side close to the fence, preventing the dust from falling everywhere on the ground. After the ground is dry, the dust floats in the air again. At the same time, the water mist in the low flow layer can also continuously moisten the ground.

[0026] 3. When local dust reduction is required in the storage yard, the controller controls the rotary motor to start, and the rotary motor drives the two rotary tubes to rotate, so that the sprinkler gun rotates to the area facing the dust reduction. Finally, the water is transported to the sprinkler gun through the pipe in the fixed pile, and the sprinkler gun sprays a water column to the area of ​​local dust reduction, so that the water in the water column mixes with the dust in the target area and settles, completing the effect of dust reduction in the local area.

[0037] As a specific embodiment of the present application, the spray direction of the spray nozzle 13 is consistent with the tangent direction of the hemispherical plate 14, and the axis of the spray nozzle 13 and the axis of the extension plate 15 are in a vertical state.

[0038] As a specific embodiment of the present application, the fixed stake 16 is arranged between the two fences 1, the top of the fixed stake 16 is provided with a water gun 17, the water gun 17 is composed of two groups of rotating pipes 18, the water gun 17 is rotated in multiple directions through the rotating pipe 18, and the rotating pipe 18 is driven by a rotating motor.

[0039] As a specific embodiment of the present application, the top plate 12 is provided with a plurality of mixing tanks 19 away from the hemispherical plate 14 side, the mixing tanks 19 are provided with atomizing ports 20 therebetween, the atomizing ports 20 are also communicated with the pipeline in the top plate 12, and the spray angle of the atomizing port 20 is inclined to the side close to the mixing tank 19.

[0040] As a specific embodiment of the present application, the cross section of the mixing tank 19 is trapezoidal, and the distance between the mixing tank 19 away from the top plate 12 side is greater than the distance between the mixing tank 19 close to the top plate 12 side.

[0041] As a specific embodiment of the present application, the mixing tank 19 is provided with a right-angle tank 21 away from the atomizing port 20 side, and the middle part of the right-angle tank 21 is provided with a gap.

[0042] As a specific embodiment of the present application, the side edge axis of the right-angle tank 21 side is in parallel with the axis of the extension plate 15.

[0043] The working principle of the present application is as follows:

[0044] The water pump draws water from the external water source, and then the water is transported to the pipeline between the bottom plate 11 and the top plate 12 through the water conveying pipe, and then the water is transported to the spray port 13 through the pipeline. After the water is atomized in the spray port 13, the water mist is sprayed out. The water mist is sprayed out towards the side close to the hemispherical plate 14. The water mist moves along the side edge of the hemispherical plate 14 towards the side close to the extension plate 15, and moves along the extension plate 15 towards the center of the stockyard. Since the spraying direction of the spray port 13 is consistent with the tangent direction of the hemispherical plate 14, and the axis of the spray port 13 is perpendicular to the axis of the extension plate 15, the direction of the water mist when sprayed out is opposite to the direction of the water mist moving in the stockyard.

[0045] Since the water mist is moving along the hemispherical plate 14 and the extension plate 15 at this time, the flow rate of the water mist is at the fastest state, and the space pressure between the hemispherical plate 14 and the extension plate 15 is in a low pressure area. At this time, the air flow rate angle of the side close to the fence 1 of the stockyard is high, and the space pressure is high. Therefore, the air in the stockyard moves towards the side close to the fence 1, and a circulation is formed between the stockyard, the top plate 12 and the extension plate 15. However, when the water mist is output along the extension plate 15, the water mist moves towards the side close to the center of the stockyard, which also drives the surrounding air to move, thereby forming a layer of circulation.

[0046] When a plurality of symmetrically arranged fences 1 jointly spray water mist, the air in the center of the stockyard moves under the action of air pressure. When the air in the center of the stockyard moves, the air pressure in the center of the stockyard is lower than the air pressure directly above the stockyard. Therefore, the air directly above the stockyard flows downward, so that the air directly above the stockyard flows towards the center of the stockyard. Through the action of air pressure, the air at the top flows towards the center of the stockyard, so that the dust in the stockyard is suppressed within the range surrounded by the fence 1, and the dust is prevented from overflowing to the side outside the fence 1.

[0047] The water mist sprayed out of the spray port 13 suppresses the dust in the stockyard. At this time, another part of the external water source is transported to the atomizing port 20 through the pipeline, and is sprayed out from the atomizing port 20. Since the spraying angle of the atomizing port 20 is inclined towards the side close to the mixing tank 19, the water mist sprayed out of the atomizing port 20 moves along the mixing tank 19, and flows from the top of the top plate 12 towards the side close to the bottom plate 11.

[0048] At this time, a layer of circulating flow has been formed in the fence 1, so that the air in the center of the yard drives the dust to flow to the side close to the fence 1. When the mixed air moves to one side of the top plate 12, the water mist sprayed by the atomizing port 20 flows along the mixing groove 19. At this time, the flow rate in the mixing groove 19 is greater than the flow rate of the mixed air, so that the mixed air is sucked to the mixing groove 19. The cross section of the mixing groove 19 is trapezoidal, and the mixed air flows away from the side of the top plate 12 to the side of the mixing groove 19 close to the top plate 12 after being close to the mixing groove 19, so that the mixed air is mixed with the water mist in the mixing groove 19, that is, the attachment of the water mist and the dust is completed, so that the volume of the dust is increased;

[0049] When the mixed air and the water mist mixed by the mixing groove 19 flow to the right angle groove 21, since the middle part of the right angle groove 21 is provided with a gap, and at this time the water mist and the dust are mixed and attached, and then the air and the water mist drive the dust to flow along the right angle groove 21. When the dust passes through the curved part of the right angle groove 21, the weight of the dust increases due to the influence of the water mist, and then the dust is thrown out under the action of centrifugal force. The dust is discharged through the gap in the middle part of the right angle groove 21, realizing the effect of dust falling. Since the side axis of one side of the right angle groove 21 is parallel to the axis of the extension plate 15, the end of the right angle groove 21 is the same as the extension plate 15, which plays a role in guiding the flow direction of the water mist. Then the air and the water mist flow to the side close to the center of the yard through the right angle groove 21. The air drives the water mist to move during the flow, which provides a certain power for the water mist to move to the center of the yard. And the air flow rate in the mixing groove 19 and the right angle groove 21 is further increased due to the influence of the gap in the groove;

[0050] Through the guidance of the extension plate 15 and the right angle groove 21, the water mist forms two flow layers of high and low heights, so that the two layers of water mist flow together from the fence 1 to the center of the yard. The air mixed with dust in the yard moves in the two height flow layers and forms circulating flow in the two height flow layers. The air in the yard is suppressed in the two height flow layers, which avoids the spread of dust outward. At the same time, the air is driven to flow to the side close to the fence 1 by air pressure, and the dust falling treatment is completed in the mixing groove 19.

[0051] It will be apparent to those skilled in the art that the application is not limited to the details of the above-exemplified embodiments and that the present application can be implemented in other particular forms without departing from the spirit or essential characteristics of the present application. The embodiments should therefore be considered in all respects as illustrative and not restrictive, the scope of the application being indicated by the appended claims rather than by the above description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. No reference signs in the claims should be considered as limiting the scope of the claims with respect to the figures of the patent document.
