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 prevention and control. Background Art

[0002] With the continuous development of the economy, environmental pollution is increasing, especially air pollution. Current air pollution is mainly caused by dust and haze. Dust from construction sites, especially from muck trucks loading and unloading muck, introduces large amounts of particulate pollutants into the atmosphere. Dust from loading and unloading can be suppressed by installing a simple, large-scale sprinkler network at the loading and unloading site, spraying atomized water jets. For other types of air pollution, such as those occurring within factories, schools, and construction sites, miniaturized air pollution control spray equipment can be used.

[0003] Patent publication number CN113134433A discloses an adjustable uniform spraying device for air pollution prevention and control, relating to the field of air pollution control technology. The device comprises a cart with a pair of base plates mounted on the top of the cart. The tops of the pair of base plates are fixedly connected to upright posts. One end of the pair of upright posts is rotatably connected to a common air duct. The air duct includes a first air outlet and a second air outlet. A blowing unit is mounted within the air duct. A spraying unit is mounted within the air duct. The spraying unit is connected to the first and second air outlets, respectively. A spray swinging unit is mounted on the spraying unit. This invention enables swinging spraying, increasing the spraying range and achieving a good spraying effect. By providing a spray flow switching unit, the spraying flow rate can be adjusted, achieving different water mist spraying conditions for different sites and 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 a ring shape and staggered to spray with different flow rates as needed to obtain different water mist effects, the water mist form is correspondingly only large and small, and cannot be flexibly adjusted according to actual needs. Moreover, 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 air from the middle surrounded by the nozzle. 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 most of it is dispersed to the surroundings, resulting in uneven spraying and poor spraying effect. The 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 atomized sprayed treatment liquid, 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.

[0030] To make the objectives, technical solutions and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0031] Example 1

[0032] like Figures 1-9 As shown, an adjustable uniform spraying device for air pollution control includes a mounting base 1, with a connecting transfer arc tube 21 and a T-shaped spray main pipe 2 fixedly connected on the front and rear sides of the bottom of the mounting base 1. The front side of the mounting base 1 has a movable cavity, and a plurality of swingable spray heads 23 are arranged in a circular array on the front side of the movable cavity. A cone-shaped blocking rod 3 is movably provided in the spray head 23. There are pressurized chambers on both sides of the movable cavity. A one-way exhaust valve pipe 24 is fixedly connected between the pressurized chamber and the T-shaped spray main pipe 2. The lower wall of the pressurized chamber has a one-way air supply groove connected to the outside world.

[0033] A treatment liquid tank 5 is fixedly connected to the bottom of the mounting base 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 that can move along the axial direction is movably inserted in the middle of the treatment liquid tank 5. An opening and closing component is movably provided on the top of the suction pipe 51. The opening and closing component includes a damping cylinder 7 fixedly connected to the right side of the suction pipe 51, and a crank ball valve 72 that movably penetrates the damping cylinder 7 is rotatably connected in the suction pipe 51.

[0034] A mounting slot is provided at the bottom rear side of the mounting base 1 , and a rear wall of the mounting slot is provided with a plurality of mounting screw holes.

[0035] When in use, the mounting base 1 is connected to the corresponding enclosure or support by using the mounting card slot, and the mounting base 1 is fixed with bolts in conjunction with the mounting screw holes. The two sides or one side of the T-shaped spray pipe 2 are connected to the spray water input pipe 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 a 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, the water release gap of the nozzle 23 is adjusted from the inside by using each cone head blocking rod 3 to adjust the flow rate. Not only does it not affect the normal swing spraying of the nozzle 23, but it can also 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 treatment liquid spraying is required, the release and stirring mechanisms of the treatment liquid are operated synchronously. Since the crank ball valve 72 is blocked by the damping cylinder 7 when it opens, the passage from the suction pipe 51 to the T-shaped spray main pipe 2 is delayed in opening, 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 yet 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 accelerated and the pressure is reduced according to the Venturi effect, so that the treatment liquid is automatically sucked into the suction pipe 51 to be mixed and diluted with water and air, and then transported to each nozzle 23 for spraying.

[0036] Example 2

[0037] Based on the above embodiments, Figure 1-Figure 5As shown, the front side of the movable chamber is rotatably connected with a cross-axis tube 22, 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 which is respectively connected with 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. The top of the cross-axis tube 22 is slidably inserted with a guide column 32 which passes through the nozzle 23. The guide column 32 is coaxial with the cross-axis tube 22. The bottom of the guide column 32 is fixedly inserted with a pin column 33 which is movably clamped with the inclined groove 31. The front side of the movable chamber is slidably clamped with an arc plate 34. The guide column 32 is rotatably connected to the arc plate 34. The front side of the movable chamber is rotatably connected with an adjusting bolt 35 which is threadedly connected to the arc plate 34.

[0038] The inner wall of the nozzle opening of the nozzle 23 and the cone-shaped blocking rod 3 are designed to be conical.

[0039] 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 the 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, and the spray flow rate is thereby 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.

[0040] Example 3

[0041] 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 that is movably engaged with the rectangular groove is provided on the upper wall of the driving disk 4. 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 that is 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.

[0042] During spraying, the control motor 1 drives the drive shaft 42 to rotate the drive disk 4, and the drive disk 4 drives the boss 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. The rectangular groove of the corresponding middle spray head 23 drives the boss 2 44 to make the arc-shaped elastic piston column 43 deflect back and forth. The arc-shaped elastic piston column 43 then uses the boss 2 44 to drive the remaining rectangular grooves on both sides to move, thereby driving the remaining spray heads 23 to swing back and forth synchronously to spray. Since the spray heads 23 are arranged in an arc shape, the spray range at the edge is improved compared to that of a straight line arrangement. Therefore, when each spray head 23 swings back and forth to spray, the coverage is wider and the spraying effect is better.

[0043] When each nozzle 23 swings back and forth to spray, due to the reciprocating deflection of the arc-shaped elastic piston column 43, the arc-shaped elastic piston column 43 penetrates into the corresponding pressurized chamber, thereby pressing the air in the pressurized chamber into the T-shaped spray main pipe 2 through the one-way exhaust valve pipe 24, realizing water and air mixing, enhancing the atomization effect when the nozzle 23 sprays, and avoiding the uneven spray dispersion caused by the use of high-pressure air direct blowing. 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, thereby ensuring the stability of the spray atomization effect.

[0044] Example 4

[0045] Based on the above embodiments, Figure 6 and Figure 8 As shown, the front and rear sides of the lower wall of the mounting base 1 are rotatably connected to the shaft disc 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 fixedly sleeved with a plurality of groups of staggered stirring blades 62 along the axial direction. Each group of stirring blades 62 is arranged in a circular array and tilted.

[0046] 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 a friction cone groove is provided 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. The lower wall of the mounting seat 1 is rotatably connected to an adjusting screw 68 threadedly connected to the shaft block 66. The adjusting screw 68 is driven by motor 2 installed on the L-shaped support plate 11.

[0047] During spraying, the drive shaft 42 continues to operate, and the control motor 2 drives the adjusting screw 68 to rotate so that the shaft block 66 moves upward. The shaft block 66 drives the friction cone ring 67 that rotates synchronously with the drive 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 disc 6. The drive shaft 42 thereby drives the front shaft disc 6 to rotate through the friction cone ring 67, and drives the rear shaft disc 6 through the transmission belt to rotate the rotary blade shaft 61 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 the groups of stirring blades 62 are staggered, the stirring effect is good, ensuring that the components of the treatment liquid can be quickly and evenly distributed.

[0048] Example 5

[0049] Based on the above embodiments, Figure 6-Figure 7 As shown, the lower wall of the movable cavity is fixedly connected to a sleeve 64 that 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 protruding column 63 that is movably engaged with the curved ring groove 65 is provided on the top of the rotary blade shaft 61.

[0050] When the rotor shaft 61 rotates and drives the stirring blades 62 to stir the treatment liquid, the protruding column 3 63 on the top of the rotor shaft 61 moves relative to the circumference along the curved ring groove 65, thereby driving the rotor shaft 61 to move back and forth 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.

[0051] Example 6

[0052] Based on the above embodiments, Figure 8-Figure 9 As shown, the inner wall of the rear side of the damping cylinder 7 is fixedly connected to a partition 71 that is movably in contact with the crank ball valve 72, and the lower wall of the crank ball valve 72 is fixedly connected to a slide plate 73 that is movably in contact with the inner wall of the damping cylinder 7. A micro oil hole 74 and a one-way return oil 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.

[0053] The control motor 2 drives the adjusting screw 68 to rotate so that the shaft block 66 moves upward, and when the rotary vane 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 oil return 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 oil return valve groove does not allow the hydraulic oil to flow backward. Therefore, the deflection of the crank ball valve 72 is blocked, and the crank ball valve 72 cannot immediately make the suction pipe 51 open, and the telescopic spring rod 75 is stretched. Subsequently, the elastic force of the telescopic spring rod 75 can continuously form a pulling force on the crank ball valve 72, so that the crank ball valve 72 slowly deflects 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. At the same time, it avoids the use of related delayed electronic control mechanisms, and there is no need to consider the influence of high temperature and humidity outdoors, and the control is safe and reliable.

Various modifications to these embodiments will be readily 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.
