Description

Technical Field

[0001] The invention relates to the field of dust reduction equipment, and more specifically to a green construction dust reduction device. Background Art

[0002] Green environmental protection is the theme of the development of the world today, and it has attracted great attention in various fields and industries around the world, and green construction is no exception. A large amount of dust is usually generated during the operation of port coal transportation, urban road construction, raw material yards, power plant coal yards, and construction sites. Therefore, in order to respond to the call for green construction, dust suppression devices are usually installed on the working surface to suppress dust.

[0003] Existing dust suppression devices are generally divided into two categories, namely, vehicle-mounted movable dust suppression devices and column-fixed dust suppression devices. Although column-fixed dust suppression devices have some advantages in actual use, they still have the following shortcomings:

[0004] 1. The existing dust suppression device with fixed column installation usually has one nozzle on the top, which is driven by the corresponding motor to rotate circumferentially or pitch up and down. Such a structure not only has a small number of nozzles, which is not conducive to the simultaneous circumferential coverage of the area around the column, but also drives the movement of the nozzle by the motor, which increases the manufacturing cost and is not conducive to the control of production costs;

[0005] 2. The existing column-fixed dust suppression device lacks a corresponding air supply structure at the nozzle, so that the range of spraying water mist can only be adjusted by the spraying force of the nozzle, which affects the uniformity and spraying range of the spraying water mist;

[0006] Therefore, we proposed a green construction dust reduction device to solve the above problems. Summary of the invention

[0007] In view of the problems existing in the prior art, the purpose of the present invention is to provide a green construction dust suppression device, which opens no less than 4 air outlets on the outer wall of the top of the hollow column, and no less than 4 arc-shaped nozzles are arranged inside the air outlet, so that the top of the hollow column can spray water mist in a circular area at the same time, and the number of arc-shaped nozzles is large, so that the spraying surface is more uniform and the water mist spraying performance is stronger; at the same time, the pitch angle of the arc-shaped nozzle is adjusted by a winch mechanism in conjunction with a steel cable and a pulling member, which has a simple structure, low manufacturing cost, low maintenance rate, and greatly reduces the installation cost. The overall manufacturing cost and the probability of later maintenance are reduced; and a blower for air supply is installed inside the equipment cabinet, and is connected to the inside of the hollow column through a blower pipe, so that air can be blown at the air outlet, and the uniformity and spraying range of the water mist sprayed by the arc-shaped nozzle are assisted, which is convenient for use on the construction site; and when the wind passes through the inside of the hollow column and is blown out from the air outlet, a water curtain mechanism is also provided inside the hollow column, so that water can pass through the moist cylindrical water curtain paper, thereby reducing the temperature of the wind discharged from the air outlet, which is beneficial to reducing the temperature of the surrounding area of ​​the hollow column and improving the comfort during use.

[0044] (1) The spraying and blowing principles of this green construction dust suppression device are:

[0045] First, connect the water inlet pipe 11 to the water source and start the water supply pump 8, supply water to the water pipe manifold 9 through the connection of the water inlet pipe 10, or close the valve 1001, directly connect the tap water pipe to the water pipe valve 12 to supply water to the water pipe manifold 9, and then the water enters the corresponding water supply hose 308 through several fine-tuning valves 901, and finally sprays out from the arc-shaped nozzle 307 at the air outlet 103 inside the hollow column 1 as the water supply hose 308 rises, so as to achieve the effect of spraying water mist in the annular area on the top of the hollow column 1;

[0046] By setting the fine-tuning valve 901, the water spraying amount and water spraying intensity of the corresponding arc-shaped sprinkler head 307 can be adjusted, thereby achieving the effect of zone adjustment control, which is convenient for use;

[0047] At the same time, the blower 7 is started, and the air on the outside of the equipment cabinet 2 is sucked into the blower 7 through the ventilation holes on the equipment cabinet 2, and blown into the hollow column 1 through the connection of the blower pipe 15, and continuously climbs upward inside the hollow column 1 and passes through the water curtain mechanism 4, and finally blows out at each air outlet 103, assisting the arc-shaped nozzle 307 to spray water mist in an area and a range. The hole of the hollow column 1 at the connection between the protective tube 13 and the hollow column 1 is filled with sealing mud, so that the connection between the hole of the protective tube 13 and the hollow column 1 and the connection when the water supply hose 308 passes through can be sealed, thereby improving the airtightness and reducing the probability of air leakage and water leakage. Embodiment 2

[0048] In view of the above embodiment 1, for further description, refer to Figure 3 , Figure 5 as well as Figure 6 The nozzle mechanism 3 includes an upper mounting plate 301 and a lower mounting plate 302 fixedly mounted on the inner wall of the hollow column 1. The upper mounting plate 301 and the lower mounting plate 302 are both symmetrically and equidistantly provided with not less than four sliding holes 303, and a pulling member 304 is slidably connected between two corresponding sliding holes 303 in the longitudinal direction, and a supporting spring 305 is sleeved on the top of the pulling member 304. The top and bottom of the supporting spring 305 are in contact with the top of the pulling member 304 and the top of the upper mounting plate 301 respectively, and the upper mounting plate at the position of the corresponding pulling member 304 A metal ring strip 306 is fixedly welded between 301 and the lower mounting plate 302, and no less than 4 arc-shaped nozzles 307 are rotatably connected inside the metal ring strip 306. An ear piece is fixedly welded on one side of the arc-shaped nozzle 307, and the ear piece is rotatably connected inside the pulling member 304 through a pin, and a water supply hose 308 is fixedly connected to the water inlet end at the bottom of the arc-shaped nozzle 307. A group of arc-shaped avoidance holes 309 are also opened on the lower mounting plate 302, and the bottom of the water supply hose 308 extends to the bottom of the hollow column 1 through the corresponding arc-shaped avoidance holes 309;

[0049] An air outlet 103 is provided on the outer wall of the hollow column 1 at the position of the corresponding metal ring strip 306, and the arc-shaped nozzle 307 extends to the outside of the hollow column 1 through the air outlet 103. A bearing hole 104 is also provided on the outer wall of the hollow column 1 at the position of the corresponding air outlet 103.

One side of the clamp 503 is rotatably connected to the outer wall of the hollow column 1 through a pin shaft. A steel cable 504 is fixedly connected to the bottom of the pulling member 304, and the bottom of the steel cable 504 is wound around the inner end of the winding shaft 501.

[0050] (2) The nozzle mechanism adjustment principle of this green construction dust suppression device is:

[0051] When it is necessary to adjust the pitch angle of the arc-shaped nozzle 307 inside the same metal ring strip 306, first push open the clamp 503 on the winch mechanism 5 at the bottom of the corresponding metal ring strip 306 to disengage the limit of the gear 502, and then turn the winch shaft 501 by the hand wheel to tighten or loosen the steel cable 504 from the bottom. At this time, the pulling member 304 of the nozzle mechanism 3 can be pulled down or lifted up by the connection of the steel cable 504, and then the arc-shaped nozzle 307 can be rotated up and down in the metal ring strip 306 by the rotation connection of the ear piece. After the adjustment is completed, the clamp 503 is released to clamp the gear 502, and the arc-shaped nozzle 307 can be positioned.

[0052] During this process, the support spring 305 has the effect of pulling the top of the pulling member 304 in the opposite direction, which facilitates the upward reset or adjustment of the pulling member 304. The arc-shaped avoidance hole 309 not only facilitates the insertion of the water supply hose 308, but also provides a channel for the flow of wind inside the hollow column 1. Embodiment 3

[0053] In view of the above-mentioned embodiment 1 and embodiment 2, for further description, refer to Figure 1 , Figure 7 as well as Figure 8 An inspection port 101 is provided on one side of the outer wall of the hollow column 1, and a sealing plate 102 is fixedly installed on the outer side of the inspection port 101. The water curtain mechanism 4 includes an upper limit mesh plate 401 and a lower limit mesh plate 402 fixedly installed on the inner wall of the hollow column 1, and the positions of the upper limit mesh plate 401 and the lower limit mesh plate 402 correspond to the top and bottom positions of the inspection port 101. A cylindrical water curtain paper 403 is clamped between the upper limit mesh plate 401 and the lower limit mesh plate 402, and pipeline avoidance holes 404 are provided on the upper limit mesh plate 401 and the lower limit mesh plate 402;

[0054] The drainage mechanism 6 includes an L-shaped drainage pipe 601 fixedly welded to the bottom of the hollow column 1, the bottom of the L-shaped drainage pipe 601 passes through the outside of the hollow column 1, a water leakage mesh plate 602 is fixedly installed on the inner wall of the hollow column 1 at the top of the L-shaped drainage pipe 601, a floating rod 603 is slidably connected at the center position of the water leakage mesh plate 602, a stainless steel float 604 is fixedly welded to the top of the floating rod 603, a sealing plug 605 is fixedly installed at the bottom of the floating rod 603, and the bottom of the sealing plug 605 is in contact with the top of the L-shaped drainage pipe 601.

[0055] (3) The cooling principle of the water curtain mechanism of this green construction dust suppression device is:

[0056] First, open the fine-adjusting valve 2 902 at the water pipe manifold 9, so that the water inside the water pipe manifold 9 can enter the inside of the spray pipe 14 through the fine-adjusting valve 2 902, and then rise and spray on the top of the water curtain mechanism 4, so as to continuously moisten the cylindrical water curtain paper 403 inside the water curtain mechanism 4. At this time, the wind inside the hollow column 1 passes upward from the bottom of the cylindrical water curtain paper 403 to achieve the effect of cooling, and then is discharged from the air outlet 103, and the water sprayed on the cylindrical water curtain paper 403 continuously falls to The drainage mechanism 6 is gathered together. When the water level is higher than the stainless steel float 604, the stainless steel float 604 floats up and drives the sealing plug 605 to move up and out of contact with the top of the L-shaped drainage pipe 601. At this time, the water can be discharged through the L-shaped drainage pipe 601. When the water level drops, the stainless steel float 604 and the sealing plug 605 continue to drop until the top of the L-shaped drainage pipe 601 is sealed. This structural form can achieve intermittent drainage and prevent air leakage during drainage.

[0057] The pipeline avoidance holes 404 provided on both the upper limit mesh plate 401 and the lower limit mesh plate 402 facilitate the insertion of the steel cable 504 and the water supply hose 308 and provide a channel for the flow of wind.

Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and its improved conception within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
