Description

Technical Field

[0001] The invention relates to the technical field of air pollution control, and in particular to an adjustable uniform spraying device for air pollution control. Background Art

[0002] With the continuous development of the economy, environmental pollution is getting worse, especially air pollution. The current air pollution mainly comes from dust and haze pollution. Among them, the dust from construction sites will bring a large amount of particulate pollutants into the atmosphere, especially the dust from muck trucks loading and unloading muck. For the dust caused by loading and unloading, a simple large-scale spray equipment network can be set up in the loading and unloading yard to spray atomized water jets to suppress the dust. For other air pollution such as factory areas, schools, and construction sites, small-scale air pollution prevention and control spray equipment can be used for prevention and control.

[0003] The patent with the publication number CN113134433A discloses an adjustable uniform spraying device for air pollution prevention and control, which relates to the field of air pollution control technology, including a cart, a pair of bottom plates are installed on the top of the cart, the tops of the pair of bottom plates are fixedly connected with columns, one end of the pair of columns is rotatably connected with the same wind tube, the wind tube includes a first air outlet and a second air outlet, a blowing unit is installed in the wind tube, a spray part is installed in the wind tube, the spray part is connected to the first air outlet and the second air outlet respectively, and a spray swing part is installed on the spray part. The invention can perform swing spraying, increase the range of spraying, and have a good spraying effect. By setting a spray flow switching part, the flow rate during spraying can be adjusted, so that different water mists can be sprayed according to different sites, thereby improving the air pollution control effect.

[0004] When the adjustable uniform spraying equipment for air pollution control in the above patent is used, although it can use large and small nozzles arranged in an annular and staggered manner to spray with different flow rates as needed to obtain different water mist effects, the water mist form is also only large and small, and cannot be flexibly adjusted according to actual needs. When only one of the large or small nozzles is used for a long time, the utilization value of the other nozzle is relatively lost, and the large and small nozzles cannot cooperate with each other to maximize the spraying effect; when spraying, the fan blows high-pressure wind from the middle surrounded by the nozzle, and when the nozzle swings to spray, it is affected by the high-pressure wind in the middle, and water or other treatment liquid cannot be sprayed to the middle, but mostly dispersed around, resulting in uneven spraying and poor spraying effect; spraying water or treatment liquid shares a water tank. When the treatment liquid is used in the water tank, due to the relatively low consumption rate of the treatment liquid sprayed by atomization, the spraying process is relatively long, and the necessary pre-mixing and real-time mixing functions are lacking, it is easy for the components of the treatment liquid to precipitate, and the components of the sprayed treatment liquid are uneven, resulting in poor spraying treatment effect.

[0018] To make the purpose, technical solution and advantages of the embodiments of the present invention more clear, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0019] Embodiment 1 like Figure 1-Figure 9 As shown, an adjustable uniform spraying device for air pollution prevention and control comprises a mounting seat 1, wherein the front and rear sides of the bottom of the mounting seat 1 are fixedly connected with a connecting transfer arc tube 21 and a T-shaped spray main pipe 2, the front side of the mounting seat 1 has an active cavity, a circular array of a plurality of swingable spray heads 23 are arranged in the front side of the active cavity, a cone-head blocking rod 3 is movably arranged in the spray head 23, and the left and right sides of the active cavity are provided with pressurizing chambers, a one-way exhaust valve pipe 24 is fixedly connected between the pressurizing chamber and the T-shaped spray main pipe 2, and the lower wall of the pressurizing chamber has a one-way air supply groove connected with the outside; A treatment liquid tank 5 is fixedly connected to the bottom of the mounting seat 1, and a contraction section is provided at the front of the T-shaped spray main pipe 2. A suction pipe 51 is fixedly connected between the bottom of the treatment liquid tank 5 and the contraction section. A rotary vane shaft 61 capable of moving along the axial direction is movably inserted in the middle of the treatment liquid tank 5. An opening and closing assembly is movably provided on the top of the suction pipe 51. The opening and closing assembly includes a damping cylinder 7 fixedly connected to the right side of the suction pipe 51, and a crank ball valve 72 movably penetrated by the damping cylinder 7 is rotatably connected in the suction pipe 51.

[0020] A mounting slot is provided at the bottom of the rear side of the mounting seat 1, and a rear wall of the mounting slot has a plurality of mounting screw holes.

[0021] When in use, the mounting base 1 is connected to the corresponding enclosure or support by using the mounting card slot, and then the mounting base 1 is fixed by using bolts and mounting screw holes. The two sides or one side of the T-shaped spray pipe 2 are connected to the spray water input pipeline as needed. When spray water is pumped into the T-shaped spray pipe 2, the spray water passes through the T-shaped spray pipe 2 into the transfer arc tube 21 and automatically enters each nozzle 23 for spraying. When spraying, each nozzle 23 is controlled to swing synchronously, and the pressurized chamber is used to press air and water into the T-shaped spray pipe 2 through the one-way exhaust valve pipe 24 to directly Mixing avoids the interference of high-pressure wind on the sprayed water mist, and the spray atomization effect is better. Since each nozzle 23 is arranged in a circular array on the front side of the active cavity, each nozzle 23 is equivalent to an arc arrangement, and the spray range of the edge is improved compared with the straight line arrangement, the coverage is wider, and the spray effect is enhanced. When it is necessary to adjust the spray flow and water mist effect, each cone head blocking rod 3 is used to adjust the water flow release gap of the nozzle 23 from the inside to adjust the flow, which not only does not affect the normal swing spray of the nozzle 23, but also can obtain different water mist forms according to needs, thereby To improve the spraying effect, the treatment liquid tank 5 is provided to facilitate the separation of water and liquid, thereby meeting different treatment spraying requirements. When the treatment liquid spraying is required, the release and stirring mechanism of the treatment liquid is operated synchronously. Since the opening of the crank ball valve 72 is blocked by the damping cylinder 7, the passage from the suction pipe 51 to the T-shaped spray main pipe 2 is delayed to open, and the treatment liquid will not be released temporarily, while the rotary vane shaft 61 can rotate to stir the treatment liquid in the treatment liquid tank 5. At the same time, the rotary vane shaft 61 moves axially, which makes the stirring of the treatment liquid more rapid and sufficient. During the period when the release channel has not been fully opened, the precipitated components can be fully stirred and dispersed evenly by the rotary blade shaft 61, and after the release channel of the subsequent suction pipe 51 is fully opened and the treatment liquid is continuously released, the treatment liquid is continuously stirred to avoid uneven spraying of the treatment liquid affecting the treatment effect. After the release channel of the suction pipe 51 is fully opened, the flow rate at the contraction section at the front of the T-shaped spray main pipe 2 is increased and the pressure is reduced according to the Venturi effect, so that the treatment liquid is automatically sucked in through the suction pipe 51 to be mixed and diluted with water and gas, and transported to each nozzle 23 for spraying.

[0022] Embodiment 2 Based on the above embodiments, Figure 1-Figure 5As shown, a cross-axis tube 22 is rotatably connected to the front side of the movable cavity, and the nozzle 23 is fixedly sleeved on the cross-axis tube 22. The bottom of the cross-axis tube 22 has a T-slot respectively connected to the nozzle 23 and the transfer arc tube 21. The cone-head blocking rod 3 is slidably clamped in the cross-axis tube 22. The rear part of the cone-head blocking rod 3 has a groove, and the front and rear walls of the groove are provided with inclined grooves 31. A guide column 32 that passes through the nozzle 23 is slidably inserted at the top of the cross-axis tube 22. The guide column 32 is coaxial with the cross-axis tube 22, and a pin column 33 movably clamped with the inclined groove 31 is fixedly inserted at the bottom of the guide column 32. An arc plate 34 is slidably clamped at the front side of the movable cavity. The guide column 32 is rotatably connected to the arc plate 34, and the front side of the movable cavity is rotatably connected to an adjusting bolt 35 threadedly connected to the arc plate 34.

[0023] The inner wall of the nozzle opening of the nozzle 23 and the cone-shaped plugging rod 3 are designed to be conical.

[0024] When it is necessary to adjust the spray flow rate to change the water mist form, rotate the adjusting bolt 35 to drive the arc plate 34 to move downward, and the arc plate 34 drives each guide column 32 to move downward. The guide column 32 drives the pin 33 to squeeze the inclined groove 31, and the inclined groove 31 drives the cone head blocking rod 3 to move toward one side of the nozzle 23 outlet. The gap between the front end of the cone head blocking rod 3 and the inner wall of the nozzle 23 outlet is reduced, the spray flow rate is reduced, and the corresponding water mist form is changed. Since the guide column 32 is coaxial with the cross-axis tube 22, when each nozzle 23 swings and sprays, the guide column 32 is driven to rotate freely on the arc plate 34 without interfering with the movement of the arc plate 34. The flow adjustment can be carried out synchronously when the nozzle 23 swings, and the adjustment is convenient and easy to observe.

[0025] Embodiment 3 Based on the above embodiments, Figure 1-Figure 3 and Figure 6 As shown, a rectangular groove is provided at the rear end of the nozzle 23, and a driving disk 4 is rotatably connected to the lower wall of the movable cavity. A convex column 41 movably engaged with the rectangular groove is provided on the upper wall of the driving disk 4, and a driving shaft 42 is fixedly connected to the lower wall of the driving disk 4. An L-shaped support plate 11 is fixedly connected between the lower wall of the mounting seat 1 and the treatment liquid tank 5. The driving shaft 42 is driven by a motor 1 installed at the bottom of the L-shaped support plate 11. An arc-shaped elastic piston column 43 is slidably connected between the two pressurizing chambers. A convex column 2 44 movably engaged with each rectangular groove is provided on the lower wall of the arc-shaped elastic piston column 43, and the convex column 2 44 is located above the convex column 1 41.

[0026] During spraying, the control motor 1 drives the driving shaft 42 to rotate the driving disk 4, and the driving disk 4 drives the convex column 1 41 to move the rectangular groove at the rear end of the spray head 23, so that the middle spray head 23 can swing back and forth to spray, and the rectangular groove of the corresponding middle spray head 23 drives the convex column 2 44 to make the arc elastic piston column 43 deflect back and forth, and the arc elastic piston column 43 drives the remaining rectangular grooves on both sides to move by the convex column 2 44, thereby driving the remaining spray heads 23 to swing back and forth synchronously to spray, because the spray heads 23 arranged in an arc shape have a spray range at the edge thereof that is improved compared with those arranged in a straight line, so when each spray head 23 swings back and forth to spray, the coverage is wider and the spray effect is better; When each nozzle 23 reciprocates and swings for spraying, due to the reciprocating deflection of the arc-shaped elastic piston column 43, when the arc-shaped elastic piston column 43 penetrates into the corresponding pressurized chamber, the air in the pressurized chamber is pressed into the T-shaped spray main pipe 2 through the one-way exhaust valve pipe 24, so that water and air are mixed, and the atomization effect of the nozzle 23 when spraying is enhanced, and the uneven spray dispersion caused by the direct blowing of high-pressure wind is avoided. When the arc-shaped elastic piston column 43 moves outward from the pressurized chamber, the outside air can be sucked into the pressurized chamber for replenishment through the one-way air supply groove connected to the outside world. The design of two pressurized chambers is convenient for continuously mixing air into the T-shaped spray main pipe 2 to ensure the stability of the spray atomization effect.

[0027] Embodiment 4 Based on the above embodiments, Figure 6 and Figure 8 As shown, the front and rear sides of the lower wall of the mounting seat 1 are rotatably connected with shaft discs 6, and the rotary blade shaft 61 is slidably engaged in the rear shaft disc 6. The outer periphery of the bottom of the rotary blade shaft 61 is axially fixedly sleeved with a plurality of groups of staggered stirring blades 62, and each group of stirring blades 62 is arranged in a circular array and tilted; A transmission belt is movably connected between the shaft discs 6 on the front and rear sides. The front shaft disc 6 is movably connected to the drive shaft 42 and has a friction cone groove at the bottom. A shaft block 66 is slidably connected between the drive shaft 42 and the L-shaped support plate 11. A friction cone ring 67 corresponding to the friction cone groove is rotatably connected to the shaft block 66. The friction cone ring 67 is slidably connected to the drive shaft 42. An adjusting screw 68 threadedly connected to the shaft block 66 is rotatably connected to the lower wall of the mounting seat 1. The adjusting screw 68 is driven by motor 2 installed on the L-shaped support plate 11.

[0028] During spraying, the driving shaft 42 keeps running, and the control motor 2 drives the adjusting screw 68 to rotate so that the shaft block 66 moves upward, and the shaft block 66 drives the friction cone ring 67 which rotates synchronously with the driving shaft 42 to move upward, and drives the friction cone ring 67 to abut against the friction cone groove at the bottom of the front shaft disk 6. The driving shaft 42 drives the front shaft disk 6 to rotate through the friction cone ring 67, and drives the rear shaft disk 6 through the transmission belt to rotate the rotary blade shaft 61, so as to stir the treatment liquid in the treatment liquid tank 5. During stirring, since each group of stirring blades 62 is arranged in a circular array and tilted, and each group of stirring blades 62 is staggered, the stirring effect is good, ensuring that the components of the treatment liquid can be quickly uniform.

[0029] Embodiment 5 Based on the above embodiments, Figure 6-Figure 7 As shown, the lower wall of the movable cavity is fixedly connected with a sleeve 64 which is movably sleeved on the top of the rotary blade shaft 61. A closed curved ring groove 65 is provided in the sleeve 64. The curved ring groove 65 is symmetrically designed on both sides. A convex column 63 which is movably engaged with the curved ring groove 65 is provided on the top of the rotary blade shaft 61.

[0030] When the impeller shaft 61 rotates to drive the stirring blades 62 to stir the treatment liquid, the protruding column 3 63 on the top of the impeller shaft 61 moves relative to the circumference along the curved ring groove 65, thereby driving the impeller shaft 61 to move reciprocatingly up and down while rotating. The stirring effect of each group of stirring blades 62 on the treatment liquid is enhanced, thereby accelerating the mixing speed of the treatment liquid that has not been used for a long time, so that it can be put into use quickly and reliably.

[0031] Embodiment 6 Based on the above embodiments, Figure 8-Figure 9 As shown, a partition plate 71 which is movably abutted against a crank ball valve 72 is fixedly connected to the inner wall of the rear side of the damping cylinder 7, a slide plate 73 which is movably abutted against the inner wall of the damping cylinder 7 is fixedly connected to the lower wall of the crank ball valve 72, a micro oil hole 74 and a one-way oil return valve groove are provided on the slide plate 73, and a telescopic spring rod 75 is movably hinged between the right end of the crank ball valve 72 and the shaft block 66.

[0032] The control motor 2 drives the adjusting screw 68 to rotate so that the shaft block 66 moves upward, and when the rotary blade shaft 61 is driven to stir the treatment liquid, the shaft block 66 synchronously pulls the telescopic spring rod 75 to drive the crank ball valve 72 to deflect. Since the damping cylinder 7 is initially completely filled with hydraulic oil, and the one-way return oil valve groove only allows the hydraulic oil to flow from back to front, when the crank ball valve 72 deflects forward, the micro-oil hole 74 allows less hydraulic oil to pass through, and the one-way return oil valve groove does not allow the hydraulic oil to flow backward, so the deflection of the crank ball valve 72 is blocked, and the crank ball valve 72 cannot immediately open the suction pipe 51, and the telescopic spring rod 75 is stretched. The elastic force of the telescopic spring rod 75 can subsequently continuously form a pulling force on the crank ball valve 72, so that the crank ball valve 72 can slowly deflect until it is completely deflected to open the suction pipe 51 to release the treatment liquid. This design ensures that the treatment liquid can be fully pre-stirred before release, thereby improving the spray treatment effect and avoiding the use of related delayed electronic control mechanisms. There is no need to consider the influence of high temperature and humidity outdoors, and the control is safe and reliable.

[0033] The above description of the disclosed embodiments enables one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but rather to the widest scope consistent with the principles and novel features disclosed herein.
