Description

Technical Field

[0001] The present invention relates to the technical field of spray equipment, and more particularly to fully automatic high-pressure spray equipment and its application in mine dust control. Background Art

[0002] A large amount of dust will be generated during mining, crushing, transportation, etc. This dust not only affects the health of workers, but also damages equipment and may cause safety accidents. Therefore, fully automatic high-pressure spray equipment, namely high-pressure fog pile equipment, will be installed in the mine. The water flow will be broken into fine water mist through the high-pressure atomizing nozzle to improve the environment of the mine and surrounding areas.

[0003] The Chinese patent with application number 202211560017.3 discloses a dust suppression spray device for mining areas, which includes a base, a spray assembly, and a cleaning and antifreeze assembly. A support tube is fixed to the upper end of the base; the mounting seat is rotatably connected to the upper end of the support tube, the nozzle is rotatably connected to the mounting seat, a water pump 1 is connected to the nozzle, and a stop valve 1 is connected in series between the two; the liquid collecting shell is fixed on the mounting seat, the spray end of the nozzle can be limited in the liquid collecting shell, the liquid inlet end of the liquid storage tank is connected to the liquid collecting shell, the liquid outlet end of the liquid storage tank is connected to the nozzle, and a water pump 2 and a stop valve 2 are connected in series between the two. The device has the function of spraying water mist for dust reduction, and the circulating water flow can prevent the nozzle from freezing due to low temperature.

[0004] The Chinese patent with application number 202411472562.6 discloses a spray dust suppression device for mining, which includes a dust suction cylinder and a suction fan. The dust suction cylinder includes an outer cylinder layer and an inner cylinder layer. A trumpet-shaped diffusion structure 1 is formed at the first end of the inner cylinder layer. Multiple mist nozzles 1 are arranged at intervals on the periphery of the diffusion structure 1. The water mist sprayed by the multiple mist nozzles 1 forms a trumpet-shaped spray water curtain. The suction fan is arranged at the second end of the inner cylinder layer. A dust filtering device is arranged inside the inner cylinder layer. A dust collecting device is arranged below the dust filtering device. A trumpet-shaped diffusion structure 2 is formed at the first end of the outer cylinder layer. An air duct is formed between the inner cylinder layer and the outer cylinder layer. The suction fan sucks wind into the inner cylinder layer and discharges the wind from between the diffusion structure 1 and the diffusion structure 2 through the air duct. The device has the function of spraying a trumpet-shaped spray water curtain to prevent dust from spreading.

[0005] The current fully automatic high-pressure spray equipment still has the following problems:

[0006] 1. The mining operation area is usually relatively open, and the wind speed outside is relatively high, which will affect the sprayed water mist, causing the dust reduction area to shift, thereby affecting the dust reduction effect.

[0007] 2. The dust particles after dust reduction will be raised again due to the passing of vehicles, forming secondary dust, which will not only cause secondary impact on the surrounding environment, but also increase the workload of dust reduction equipment.

[0008] 3. The water mist sprayed from the high-pressure nozzle stays in the air for a short time, which limits the range of dust reduction. Although the water flow rate can be increased by increasing the water pressure and the dust reduction range can be increased, excessive pressure will cause increased equipment wear and increase the pressure of the pipeline, resulting in the risk of rupture.

DETAILED DESCRIPTION

[0047] In order to make the purpose, technical scheme and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention, that is, the embodiments described are only part of the embodiments of the present invention, rather than all of the embodiments. The components of the embodiments of the present invention described and shown in the drawings herein can be arranged and designed in various different configurations.

[0048] Depend on Figures 1 to 11It is provided, comprising a main unit, a vertical pole 102, and a water mist spray gun 103 arranged on the top of the vertical pole 102. A water tank, a water pump, a control device, a filter and other structures are installed inside the main unit. The filter is connected between the water pump and the water tank through a pipeline. The water tank is connected to an external water supply device. The control device controls the water pump. The water supply device supplies water to the water tank. The water flows into the water pump after being filtered by the filter and is then transported out by the water pump. The main unit is of an existing structure and will not be described in detail here. The water mist spray gun 103 is connected to the water supply device in the main unit through a water supply pipe. The water supply device provides a water source for the water mist spray gun 103 for spray dust reduction operations. The water mist spray gun 103 is also called a high-pressure micro-mist nozzle. It is an existing device for breaking water flow into fine water mist of 10-50 microns. The top of the vertical pole 102 is connected to a reciprocating swing component, which drives the water mist spray gun 103 to swing back and forth, thereby expanding the range of dust reduction. The top of the reciprocating swing component is connected to a support frame 104, and the top of the support frame 104 is connected to a rotating head 105. The water mist spray gun 103 is fixedly connected to the rotating head 105, and the outside of the rotating head 105 is provided with a first jet frame 106 and the second jet rack 107, the first jet rack 106 and the second jet rack 107 are located on both sides of the water mist spray gun 103, the sprayed airflow increases the speed of the water mist and thus increases the range of dust reduction, because the direction of the airflow is consistent with that of the water mist, it can inhibit both sides of the water mist and avoid irregular diffusion of the water mist, thereby reducing the evaporation of the water mist, and at the same time can form a barrier on both sides of the water mist to reduce the impact of external wind on the water mist. It should be noted that the sprayed water mist will evaporate, and the evaporated water mist is also one of the effects of dust reduction. After the water mist evaporates, it will increase the humidity of the air and reduce the surrounding temperature. After the dust absorbs water, its volume increases and its weight increases, thereby falling to the ground and playing a role in dust reduction. At the same time, it also acts on the dust before evaporation, thus achieving the dust reduction effect.

[0049] refer to Figure 2The support frame 104 and the rotating head 105 are provided with a central air flow channel 112 inside, and the central air flow channel 112 is externally connected to an air supply device. The air supply device first transports the gas into the central air flow channel 112, and then transports the gas to the first jet rack 106 and the second jet rack 107 through the central air flow channel 112, so as to avoid the situation where the first jet rack 106 and the second jet rack 107 use an external air pipe. The internal circumferential array of the rotating head 105 has a first air supply channel 113 and a second air supply channel 114. The air inlets of the first air supply channel 113 and the second air supply channel 114 are located on the same plane. The first air supply channel 113 supplies air to the first jet rack 106, and the second air supply channel 114 supplies air to the second jet rack 107. The first air supply channel 113 is used to supply air to the first jet rack 106, and the second air supply channel 114 is used to supply air to the second jet rack 107. A driving cavity 115 is provided in the channel 113 and the second air supply channel 114. A cover 116 is slidably connected to the driving cavity 115. Annular ribs are provided at the bottom of both sides of the cover 116. When the cover 116 is located at the top, the annular ribs will block the air outlet of the channel to avoid the reverse flow of air. A driving column 117 is connected to the bottom of the cover 116. When the cover 116 moves downward, the driving column 117 at the bottom is driven to extend downward. The cover 116 and the driving cavity 115 are connected by a spring. A roller is connected to the bottom of the driving column 117. When the driving column 117 extends downward, it will come into contact with the inclined surface at the top of the inner cam disc 109 or the outer cam disc 110. The roller can reduce the friction during contact.

[0050] refer to Figure 3 and Fig.11, the outer ring surface of the support frame 104 is rotatably connected with an inner ring airflow frame 108, and the following connection method is provided, that is, the two are connected through a bearing, and an inner airflow ring 201 is arranged on the top of the inner ring airflow frame 108, no matter which first air supply channel 113 the airflow is in, it can enter the inner airflow ring 201, so as to supply the gas to the first injection frame 106, and at the same time, the sleeve cover 116 in the other first air supply channel 113 is located at the top, and the retaining edge at the bottom blocks the air outlet, so that the airflow cannot enter other inner airflow rings 201, and the inner ring airflow frame 108 is fixedly connected with an inner cam disc 109, and the top of the inner cam disc 109 is provided with an inclined surface, when the first air supply channel When the driving column 117 in the channel 113 extends out, the inner cam disc 109 will be driven to rotate through the inclined surface until it moves to the lowest point of the inner cam disc 109. The outer annular surface of the inner ring airflow frame 108 is connected to the first jet frame 106. The inner ring airflow frame 108 will drive the first jet frame 106 to rotate, so that the airflow nozzle points to the incoming wind direction. The outer annular surface of the inner cam disc 109 is rotatably connected to the outer cam disc 110. Preferably, the two are connected through a bearing. The tops of the inner cam disc 109 and the outer cam disc 110 are provided with inclined surfaces, and the inclined surfaces are arranged toward the jet frames, that is, the first jet frame 106 and the second jet frame 107 are located at the lowest point of the inclined surface. The inclined surface condition refers to Fig.11 The outer ring surface of the outer cam disc 110 is fixedly connected with an outer ring airflow frame 111. When the second air supply channel 114 located on one side of the second jet frame 107 is connected, the driving column 117 in the second air supply channel 114 will also extend downward until the driving column 117 moves to the lowest point of the inclined surface. Since the jet frame is located at the lowest point of the inclined surface, the jet frame will rotate in the same direction as the driving column 117, thereby driving the outer ring airflow frame 111 on this side to rotate. The outer ring surface of the outer ring airflow frame 111 is connected to the second jet frame 107. The first The air supply channel 113 is connected to the first jet rack 106, and the second air supply channel 114 is connected to the second jet rack 107. A wind direction sensor is provided on the top of the rotating head 105. Specifically, when the wind direction sensor detects the incoming wind direction, the first air supply channel 113 or the second air supply channel 114 on this side will be connected, thereby pushing the driving column 117 at the bottom to extend downward, and then driving the first jet rack 106 or the second jet rack 107 to rotate, and spray airflow in the incoming wind direction, so as to form an airflow barrier and reduce the influence of external wind on water mist;

[0051] Specifically, the inner ring surface of the inner ring airflow frame 108 is rotatably connected to the outer wall of the support frame 104, so it can rotate 360 ​​degrees around the support frame 104. The inner cam disc 109 and the inner ring airflow frame 108 are fixedly connected together. Since the top of the inner cam disc 109 is provided with an inclined surface, Fig.11When the top driving column 117 moves downward, it will exert downward pressure on the top of the inner cam disc 109. The inner cam disc 109 is connected to the support frame 104 through the inner circle airflow frame 108 and cannot move downward. At this time, there is a height difference on both sides of the contact position between the driving column 117 and the inner cam disc 109, so the inner cam disc 109 will drive the inner circle airflow frame 108 to rotate on the support frame 104, thereby driving the jet frame to rotate. The ejected airflow will disrupt the external wind force, reducing the influence of wind force on water mist.

[0052] Since the rotating head 105 is constantly swinging back and forth, when it rotates to the windward direction, the wind will affect the ejected airflow and water mist. The following provides a structure capable of detecting the incoming wind direction to facilitate controlling the direction of the ejected airflow: Figure 5 The top of the rotating head 105 is rotatably connected with a wind vane 118. When there is wind outside, the wind vane 118 will rotate. The bottom of the wind vane 118 is connected with a reversing disk 119 located in the rotating head 105. The internal equidistant array of the rotating head 105 has control channels 120. The number and position of the control channels 120 correspond to the first air supply channels 113 and the second air supply channels 114. The reversing disk 119 is provided with a through hole connected to the control channel 120. When the wind vane 118 is affected by wind and rotates, it will drive the bottom reversing disk 119 to rotate synchronously. At this time, the airflow in the central airflow channel 112 will enter the control channel 120 through the through hole on the reversing disk 119, and then drive the on-off component 101 to operate. The control channel 120 is connected to the on-off component 101 at one end away from the reversing disk 119. When the control channel 120 is not connected, the on-off component 101 blocks the first air supply channel 113 or the second air supply channel 114 to prevent the airflow therein from passing through. When the on-off component 101 moves downward, the airflow channel will be connected, which has the function of determining the incoming wind direction through the wind vane 118 and controlling the air path to be connected.

[0053] Specifically, refer to Figure 3, the first air supply channel 113 is located on a side of the rotating head 105 close to the first jet frame 106. Specifically, with the water mist spray gun 103 on the rotating head 105 as the center line, the first air supply channels 113 are arranged in an evenly spaced array on the side of the rotating head 105 close to the first jet frame 106, and the second air supply channels 114 are arranged in an evenly spaced array on the side close to the second jet frame 107. The top of the inner circle air flow frame 108 is provided with an inner air flow ring 201 that matches the first air supply channel 113. The inner air flow ring 201 is connected to the bottom of all the bottom first air supply channels 113. No matter which first air supply channel 113 is connected, the air flow will enter the first jet frame 106. The second air supply channel 114 is the same. The inner circle air flow frame 108 is provided with an air flow channel connecting the inner air flow ring 201 and the first jet frame 106, which is used to transport the air flow in the inner air flow ring 201 to the first jet frame 106;

[0054] refer to Figure 2 and Figure 3 The second air supply channel 114 is located on a side of the rotating head 105 close to the second injection frame 107, and an outer air flow ring 202 matching the second air supply channel 114 is arranged on the top of the outer ring air flow frame 111. The air outlet of the first air supply channel 113 is located on a side of the rotating head 105 close to the central air flow channel 112, and is connected to the inner air flow ring 201 at the bottom. The air outlet of the second air supply channel 114 is located on a side of the rotating head 105 close to the edge, and is connected to the outer air flow ring 202 at the bottom. The inner part of the outer ring air flow frame 111 is provided with an air flow channel connecting the outer air flow ring 202 and the second injection frame 107, which is used to transport the airflow in the outer air flow ring 202 to the second injection frame 107.

[0055] The wind outside is constantly changing, and the wind vane 118 above is a sensor for detecting the wind direction, which can rotate with different changes in wind direction. For example, when the wind comes from the left, the wind vane 118 rotates to the left, and the through hole on the wind vane 118 is connected with the control channel 120 in that direction. At this time, the first air supply channel 113 or the second air supply channel 114 in that direction is connected with the central air flow channel 112. At this time, the driving column 117 inside the air supply channel will move downward, and the roller at the bottom will come into contact with the inclined surface at the top of the inner cam disc 109 or the outer cam disc 110. The inclined surface refers to Fig.11, thereby driving the jet rack to rotate, and the ejected airflow forms a wind barrier to weaken the external wind force and reduce the impact of wind force on water mist; when the wind direction changes position, the wind vane 118 will also rotate, and the connected air supply channel will also change at this time, and the driving column 117 in the original air supply channel will retract upwards, and the driving column 117 in the newly connected air supply channel will extend downwards, and then drive the jet rack to rotate in time through contact with the inclined surface. When the wind direction changes to the other side, the airflow channel on the other side is connected, and drives the jet rack on the other side to move, and the airflow rack on the original side is reset under the action of the volute spring 302.

[0056] It should be noted that, since the rotating head 105 is in a reciprocating swinging state, the angle between the water flow nozzle (water mist spray gun 103) and the air flow nozzle may be 90 degrees or greater than 90 degrees. At this time, since the air flow frame has been spraying air in the direction of the incoming wind, the wind barrier blown out by the vertically arranged nozzles has the effect of disturbing the incoming wind. The vertical wind barrier can separate the wind force into two parts, one part moves toward the rear side of the rotating head 105, that is, the rotating head 105 moves away from the side of the water mist spray gun 103. Since this part of the wind force does not contact the water mist, it cannot affect the water mist. The other part of the wind force will also be offset due to the action of the wind barrier, further reducing the impact on the water mist.

[0057] When the airflow enters the control channel 120, it is necessary to make the on-off component 101 move so that the first air supply channel 113 or the second air supply channel 114 below is connected. The following provides a structure for controlling the on-off component 101 to move up and down: Specifically, refer to Figure 4 The control channel 120 is provided with an on-off cavity 203 at one end away from the reversing disk 119. The on-off assembly 101 includes an airflow baffle 204 slidably connected to the on-off cavity 203. The airflow baffle 204 moves up and down in the on-off cavity 203. The airflow baffle 204 is connected to the on-off cavity 203 through a spring. A T-shaped flow channel 205 is provided above the inside of the airflow baffle 204. The T-shaped flow channel 205 is in an inverted T shape. When the airflow in the control channel 120 pushes the airflow baffle 204 to move downward, the T-shaped flow channel 205 is connected with the channels on both sides to The air supply flow passes through, so that the air flow can flow in the first air supply channel 113 and the second air supply channel 114, and the air flow in the control channel 120 will also merge with it and enter together. The T-shaped flow channel 205 can be connected with the first air supply channel 113 and the second air supply channel 114, and the bottom of the air flow baffle 204 is blocked in the first air supply channel 113 and the second air supply channel 114. Specifically, when the upper control channel 120 is not connected, the spring drives the air flow baffle 204 to move upward, so that the bottom of the air flow baffle 204 can block the air flow channel.

[0058] The airflow entering the control channel 120 will cause the airflow baffle 204 to move to the bottom, and also maximize the channel that the airflow baffle 204 can open. It is impossible to adjust the opening size according to the wind conditions, and it is impossible to control the flow of gas in the first air supply channel 113 and the second air supply channel 114. The following provides a structure that can adjust the moving distance of the airflow baffle 204 according to the external wind force to achieve the effect of controlling the airflow size: Specifically, refer to Figure 4 , a conical portion 206 is provided at the top of the central airflow channel 112, an electromagnet 207 is fixedly connected inside the conical portion 206, a conical block 208 matching the conical portion 206 is connected to the top of the electromagnet 207, and the distance between the upper conical block 208 and the conical portion 206 is controlled by the energization of the electromagnet 207, so as to control the flow rate of the airflow, and the electromagnet 207 and the conical block 208 are connected by a spring, and when the current when the electromagnet 207 is energized becomes larger, the spring is more compressed, the gas flow that can pass through is larger, the airflow entering the control channel 120 is more, and the pushing ability of the airflow baffle 204 is greater;

[0059] The flow rate of the electromagnet 207 when it is energized needs to be controlled according to the external wind force. When the external wind force is greater, the current passing through the electromagnet 207 is greater. The following provides a structure that can detect the external wind force: Figure 5The wind vane 118 is provided with an oblique portion 209, and a trigger cavity 210 is provided in the oblique portion 209. A sliding rheostat 211 is provided in the trigger cavity 210. The sliding rheostat 211 is an existing device, which is usually composed of a resistor and a contactor (sliding arm) that can slide thereon. When the sliding arm moves along the resistor, the length of the resistor connected to the circuit can be changed, thereby changing the resistance value and controlling the current or voltage. Since it is a mature device, it will not be described in detail here. The current that can be output is different by the different positions of the slider on the sliding rheostat 211, thereby controlling the electromagnet 207. An air bag 212 is sleeved on the outer ring surface of the oblique portion 209, and the air bag 212 is filled with gas. When the external wind force is greater, the distance the air bag 212 moves on the oblique portion 209 is greater, such as Like a balloon, it moves with the wind. An arc baffle 213 located in the trigger cavity 210 is connected to the inner annular surface of the airbag 212. One side of the arc baffle 213 is connected to the slider of the sliding rheostat 211, and the other side is connected to the airbag 212. A strip-shaped slide groove that runs through to the outside is opened on the trigger cavity 210 to facilitate the up and down movement of the arc baffle 213. The arc baffle 213 is connected to the slider of the sliding rheostat 211, and the slider is connected to the airbag 212 through the arc baffle 213. When the airbag 212 moves, the slider will be driven to move on the sliding rheostat 211 through the arc baffle 213. The electromagnet 207 is electrically connected to the sliding rheostat 211. The current of the electromagnet 207 is controlled by the different positions of the slider on the sliding rheostat 211, thereby controlling the distance between the conical portion 206 and the conical block 208.

[0060] It should be noted that the sliding rheostat 211 changes the resistance through mechanical movement, adjusts the output voltage and current, and thus controls the action device to perform corresponding actions. The purpose of the electromagnet 207 is to convert the input electrical energy into mechanical energy to achieve mechanical movement, thereby controlling the distance between the conical portion 206 and the conical block 208.

[0061] When there is no wind, the conical block 208 presses on the conical portion 206, so that the airflow cannot pass through, and the first jet rack 106 and the second jet rack 107 do not spray airflow, and the first jet rack 106 and the second jet rack 107 are not reset. The following provides a structure in which the first jet rack 106 and the second jet rack 107 can be reset and can continue to spray airflow to increase the dust reduction range of water mist: Specifically, refer to Figure 6The outer ring surface of the support frame 104 is connected with a bottom support plate 301, which plays a bottom support role. The bottom support plate 301 and the inner ring airflow frame 108 are connected by a volute spring 302, and the outer ring airflow frame 111 and the rotating head 105 are connected by a volute spring 302. Specifically, when there is no wind outside, the volute spring 302 will drive the inner ring airflow frame 108 and the outer ring airflow frame 111 to reset, so that they are located on both sides of the water mist spray gun 103;

[0062] The tops of the first jet rack 106 and the second jet rack 107 are both connected with a rotating ring 303 sleeved on the rotating head 105. When the first jet rack 106 and the second jet rack 107 rotate, the rotating ring 303 will be driven to rotate on the rotating head 105. The rotating head 105 and the rotating ring 303 are provided with a reset airflow channel 304 connected to the first jet rack 106 and the second jet rack 107. The reset airflow channel 304 is located in the rotating head 105 and on both sides of the water mist spray gun 103. When the first jet rack 106 or the second jet rack 107 is reset to one side of the water mist spray gun 103 by the spring, the reset airflow channel 304 on the rotating ring 303 is reset to the other side of the water mist spray gun 103. The channel corresponds to the reset airflow channel 304, so that the airflow in the central airflow channel 112 enters the first jet rack 106 or the second jet rack 107 through the reset airflow channel 304. When there is no wind, the first jet rack 106 and the second jet rack 107 spray a quantitative airflow to expand the range of water mist spraying. The top of the vertical pole 102 is connected to an airflow disk 305, and the airflow disk 305 is connected to the central airflow channel 112. The airflow disk 305 is externally connected to an air supply device, and the air supply device conveys the airflow into the central airflow channel 112 through the airflow disk 305, avoiding the use of an external air supply pipeline, and there will be no repeated swinging to cause air pipe wear.

[0063] During use, dust may be stirred up for the second time. The following is a structure for collecting dust and reducing secondary dust pollution: Specifically, refer to Figure 7The vertical rod 102 is internally rotatably connected with a coaxially arranged rotating rod 401, and the vertical rod 102 is internally connected with a driving device 402 connected with the rotating rod 401, and the driving device 402 drives the rotating rod 401 to rotate in the vertical rod 102. The driving device 402 is preferably a reduction motor to increase the torque. The vertical rod 102 is internally provided with a first filter chamber 403 and a second filter chamber 404. The first filter chamber 403 is used to filter coarse dust, and the second filter chamber 404 is used to filter coarse dust. 4 is used to filter fine dust. A filter screen 405 is connected to the second filter chamber 404. The filter screen 405 is preferably a filter bag, which is used to filter fine dust. Centrifugal blades 406 and a scraper frame 407 are fixedly connected to the outer ring surface of the rotating rod 401. When the rotating rod 401 rotates, the centrifugal blades 406 and the scraper frame 407 are driven to rotate. The centrifugal blades 406 are located in the first filter chamber 403, and the scraper frame 407 is located in the second filter chamber 404.

[0064] When the air flow speed is high, the dust carrying capacity is large, and it is not convenient to capture the dust particles. The following structure is provided to reduce the gas flow rate: the top of the first filter chamber 403 is connected to the outside, and a baffle 410 is arranged at the air flow inlet to prevent foreign matter from entering. The interior of the first filter chamber 403 is fixedly connected with a guide plate 408, and a variable diameter channel 409 with a narrow entrance and a wide exit is formed between the bottom of the guide plate 408 and the first filter chamber 403. The incoming air flow will enter the variable diameter channel 409 under the action of the centrifugal blades 406. When it moves to the widening part of the variable diameter channel 409, according to the Bernoulli effect, the flow rate of the gas is reduced, and the dust carrying capacity is reduced, which plays a role in separating gas and solid. The wide head of the variable diameter channel 409 is connected with a baffle 410, which intercepts the solid particles in the air flow and further intercepts the coarse dust.

[0065] The airflow through the variable diameter channel 409 enters the second filter chamber 404, and enters the air compressor 508 through the pipeline after being filtered by the filter 405. After long-term use, the filter 405 and the baffle 410 will become dirty. The following provides a mechanism for cleaning the filter 405: Specifically, refer to Figures 7 to 9The top of the rotating rod 401 is connected to a cleaning disc 501 located above the baffle 410, and the cleaning disc 501 and the scraper frame 407 are both connected to scraper strips 502, which clean the baffle 410 and the filter screen 405 through the rotating scraper strips 502. The variable diameter channel 409 and the bottom of the second filter cavity 404 are provided with an ash discharge pipe 503, and the scraped dust particles are discharged into the ash storage box 507 through the ash discharge pipe 503. The top of the ash discharge pipe 503 is rotatably connected to an ash baffle plate 504, and the ash baffle plate 504 and the ash discharge pipe 503 are connected by a torsion spring, which makes the ash baffle plate 504 always cover the Above the ash discharge pipe 503, in order to prevent the gas from entering the ash storage box 507 from the ash discharge pipe 503, a driven plate 505 is connected to the top of one end of the hinge shaft close to the ash baffle plate 504, and the cleaning disc 501 and the ash scraper frame 407 are both connected with an active plate 506 that matches the driven plate 505. The driven plate 505 should protrude from the cleaning disc 501 and the ash scraper frame 407. When the cleaning disc 501 and the ash scraper frame 407 rotate, the active plate 506 above first comes into contact with the driven plate 505, pushing the ash baffle plate 504 to flip downward, so that the dust particles on the ash baffle plate 504 fall into the ash discharge pipe 503;

[0066] The scraped dust needs to be collected in one place for easy cleaning. The following is a structure that collects the dust in one place: Figure 7 The interior of the vertical pole 102 is connected to an ash box 507, and the ash discharge pipe 503 extends to the top of the ash box 507. The dust particles in the ash discharge pipe 503 will enter the ash box 507 for easy cleaning. The bottom of the interior of the vertical pole 102 is connected to an air compressor 508, and the air inlet end of the air compressor 508 is connected to the second filter cavity 404, and the air outlet end of the air compressor 508 is connected to the air flow disk 305 through an air flow pipe. The air compressor 508 is an air compressor, and can also be replaced with a device with the same gas conveying function, which is used to convey the filtered gas to the air flow disk 305.

[0067] The rotating head 105 needs to swing back and forth to expand the dust reduction range. The following provides a structure that can drive the rotating head 105 to swing back and forth: Specifically, refer to Fig. 9The reciprocating swing assembly includes a reciprocating screw rod 601 fixedly connected to the top of the rotating rod 401, and a reciprocating sleeve 602 fixedly connected to the bottom of the support frame 104. The rotating rod 401 drives the reciprocating screw rod 601 to rotate. An oblique sliding groove 603 is provided on the inner ring surface of the reciprocating sleeve 602. The interior of the vertical rod 102 is fixedly connected to a guide frame 604. The guide frame 604 is fixedly connected to the interior of the vertical rod 102, and is provided with sliding grooves arranged up and down inside to facilitate the upward and downward movement of the moving block 605. The guide frame 604 is slidably connected to the moving block 605 up and down, and the moving block 605 is close to the moving block 605. One end of the multifilament rod 601 is connected to a slider sleeved on the reciprocating screw rod 601. When the reciprocating screw rod 601 rotates, it drives the slider on the outer wall to move up and down, and the slider drives the moving block 605 to move up and down. The end of the moving block 605 close to the rotating ring 303 is connected to a slide bar 606 located in the oblique slide groove 603. When the moving block 605 moves up and down, the slide bar 606 at one end of the moving block 605 slides in the oblique slide groove 603. The reciprocating movement of the moving block 605 up and down drives the reciprocating sleeve 602 to rotate back and forth, thereby driving the top support frame 104 to rotate;

[0068] A speed reduction assembly 607 is connected between the reciprocating screw 601 and the rotating rod 401 to reduce the rotation speed of the reciprocating screw 601. The speed reduction assembly 607 is an existing device and will not be described in detail herein.

[0069] When the present invention is in use, the driving device 402 drives the reciprocating swing assembly to move through the rotating rod 401, thereby driving the upper rotating head 105 to reciprocate and swing to expand the dust reduction range. When there is no wind, the first jet frame 106 and the second jet frame 107 are located on both sides of the water mist spray gun 103, and the airflow in the central airflow channel 112 enters the first jet frame 106 and the second jet frame 107 through the reset airflow channel 304, and then is sprayed out from the upper nozzle. The sprayed airflow is used to increase the speed of the water mist to expand the dust reduction range;

[0070] When there is wind, the wind drives the weather vane 118 to rotate and drives the reversing disk 119 at the bottom to rotate. The airbag 212 on the weather vane 118 moves upward under the influence of the wind, and the electromagnet 207 is activated. At this time, air flows through the control channel 120 in the direction of the incoming wind, causing the on-off component 101 to operate. At this time, the first air supply channel 113 or the second air supply channel 114 below is connected, and then drives the first jet rack 106 or the second jet rack 107 to rotate, spraying air in the direction of the incoming wind to form a barrier. The airflow sprayed from the upper nozzle changes according to the size of the wind to reduce the impact of the wind on the water mist.

[0071] The dust stirred up for the second time will enter the first filter cavity 403 through the channel above the first filter cavity 403, enter the air compressor 508 after being filtered by the baffle 410 and the filter 405 in turn, and then be transported into the air flow disk 305 through the air compressor 508.

[0072] The above-mentioned embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
