Description

Technical Field

[0001] The invention relates to the technical field of dust control, and more specifically to an automatic dosing device for dust suppressant for building dust control. Background Art

[0002] During construction, dust suppression can not only reduce the amount of particulate matter entering the atmosphere and suppress the concentration of atmospheric particulate matter, but also reduce the incidence of pneumoconiosis and cardiovascular diseases, maintain the health of employees, and to a certain extent ensure the production safety of the enterprise and improve the overall safety level of the enterprise.

[0003] At present, in the spray dust suppression operation for dust generated during construction, a certain concentration of dust suppressant can be added to the dust suppression water to improve the dust suppression efficiency.

[0045] like Figures 1 to 8 As shown, an embodiment of the present invention provides an automatic dosing device for dust suppressants for construction dust control, including a storage barrel 1, two storage barrels 1 are provided, a feeding port 2 is provided in the middle of the upper surface of the storage barrel 1, a rubber plug is provided inside the feeding port 2, and a quantitative feeding component 3 for proportioning materials is provided on the lower surface of the storage barrel 1.

[0046] like Figure 2 As shown, the quantitative feeding component 3 includes a feed pipe 311 fixed on the lower surface of the storage barrel 1, and two second feed ports 314 are evenly opened on the outer surface of the feed pipe 311. The lower surfaces of the two feed pipes 311 are fixedly connected with a fixed sleeve 31, and two movable sleeves 33 are slidably connected inside the fixed sleeve 31. A fixed plate 39 is fixedly connected to one side of the movable sleeve 33, and a piston 37 is slidably connected inside the movable sleeve 33. A threaded rod 38 is rotatably connected to one side of the piston 37, and a scale rod 310 is fixedly connected to the edge of one side of the piston 37. A first feed port 312 and a second discharge port 34 are opened on the outer surface of the movable sleeve 33, a first discharge port 32 is opened on the outer surface of the fixed sleeve 31, and an electric push rod 313 is fixedly connected to one side of the fixed sleeve 31.

[0047] The inside of the feed pipe 311 is slidably connected with a leak-proof component 35, and the edges on both sides of the fixed sleeve 31 are fixedly connected with a collecting component 36. The output end of the electric push rod 313 is fixedly connected to one side of the fixed plate 39. The two sides of the movable sleeves 33 close to each other are fixedly connected to each other through a connecting rod. One side of the threaded rod 38 penetrates the inside of the fixed plate 39 and is connected by threads. The scale rod 310 penetrates the inside of the fixed plate 39 and slides with each other. The first discharge port 32 and the second discharge port 34 are located below the first feed port 312. The outer surface of the movable sleeve 33 is provided with a rubber pad, and the outer surface of the fixed sleeve 31 is provided with an automatic feeding component 4.

[0048] When performing dust suppression spraying on a construction site, dust suppressant concentrate and water to be diluted are added to the two storage barrels 1, and the concentration of the dust suppressant is adjusted according to actual needs. The piston 37 is driven to move inside the movable sleeve 33 by rotating the threaded rod 38. While the piston 37 moves, the scale rod 310 can be driven to slide inside the fixed plate 39. The volume inside the movable sleeve 33 is adjusted by observing the scale on the scale rod 310. When a concentration of 10% is required, the ratio of the volumes inside the two movable sleeves 33 can be controlled at 1:9. Similarly, dust suppressants of different concentrations can be adjusted. When the volume inside the movable sleeve 33 reaches the required value, the rotation of the threaded rod 38 can be stopped. The concentration of the dust suppressant can be flexibly controlled to adapt to construction environments with different dust concentrations in different sites. At this time, the electric push rod 313 is turned on to work. The electric push rod 313 pushes the two movable sleeves 33 to move. When the first feed port 312 on 3 moves to the bottom of the feed pipe 311, the liquid inside the storage barrel 1 enters into the interior of the movable sleeve 33 through the second feed port 314 and the feed pipe 311 until the interior of the movable sleeve 33 is filled, and the electric push rod 313 then pulls the movable sleeve 33 to move in the opposite direction, driving the other movable sleeve 33 to move downwardly toward the other storage barrel 1, so that the other first feed port 312 and the feed pipe 311 are aligned, and liquid is added to the inside of the other movable sleeve 33. At the same time, the second discharge port 34 on the movable sleeve 33 previously filled with liquid is aligned with the first discharge port 32, so that the liquid enters into the automatic feeding component 4. After the other movable sleeve 33 is filled, the electric push rod 313 pushes it to align the second discharge port 34 with the first discharge port 32, and the liquid enters into the automatic feeding component 4 for mixing, so that different concentrations of dust suppressant can be proportioned, which greatly improves the practicability of the device.

[0049] like Figure 3As shown, the leak-proof component 35 includes a vertical rod 351 slidably connected to the top of the feed pipe 311 and a second bucket-shaped cylinder 357 fixed to the inner surface of the movable sleeve 33, the top of the vertical rod 351 is fixedly connected to a top plate 353, the outer surface of the vertical rod 351 is sleeved with a first spring 352, the bottom of the vertical rod 351 is fixedly connected to a movable sleeve 354, the edge of the lower surface of the movable sleeve 354 is fixedly connected to the first bucket-shaped cylinder 356, and two third feed ports 355 are evenly arranged on the outside of the movable sleeve 354.

[0050] The first spring 352 is located above the feed pipe 311 , the bottom and top of the first spring 352 are fixedly connected to the feed pipe 311 and the first spring 352 respectively, and the second bucket 357 is located at the edge of the first feed port 312 .

[0051] The movable sleeve 33 is constantly sliding inside the fixed sleeve 31 in actual use, and the rubber pad on its surface will constantly rub against the side wall of the fixed sleeve 31 to cause wear, so that the extrusion pressure between the movable sleeve 33 and the fixed sleeve 31 will become smaller, and the liquid inside the storage barrel 1 is relatively large and its pressure is too high, which can easily cause the liquid inside the storage barrel 1 to flow out from between the movable sleeve 33 and the fixed sleeve 31. Therefore, a movable sleeve 354 is provided inside the feed pipe 311. When the movable sleeve 33 blocks the feed pipe 311, the movable sleeve 354 blocks the two second feed ports 314 inside the feed pipe 311, so that the pressure inside the storage barrel 1 is applied to the side wall of the movable sleeve 354. Through the two-layer blocking, the liquid can be effectively prevented from flowing out from between the movable sleeve 33 and the fixed sleeve 31. Even if there is liquid inside the feed pipe 311, the liquid pressure inside is much smaller than the extrusion pressure between the movable sleeve 33 and the fixed sleeve 31. Pressure is generated to ensure the sealing of the device. When the first feed port 312 coincides with the feed pipe 311, the movable sleeve 354 quickly enters the second bucket-shaped cylinder 357 under the elastic force of the first spring 352, so that the inclined surfaces of the first bucket-shaped cylinder 356 and the second bucket-shaped cylinder 357 contact each other, and the third feed port 355 coincides with the second feed port 314. The liquid enters the interior of the movable sleeve 33 through the third feed port 355, the second feed port 314 and the movable sleeve 354. It does not affect the normal liquid addition. When the movable sleeve 33 moves, the inclined surface of the second bucket-shaped cylinder 357 squeezes the inclined surface of the first bucket-shaped cylinder 356, and the first bucket-shaped cylinder 356 moves up. The first bucket-shaped cylinder 356 contacts the edge of the first feed port 312. As the movable sleeve 33 moves, the first bucket-shaped cylinder 356 gradually moves up and moves out from the inside of the first feed port 312, driving the movable sleeve 354 to move, thereby staggering the third feed port 355 and the second feed port 314 again, and closing the channel.

[0052] like Figure 4 and Figure 5As shown, the aggregate assembly 36 includes an arc-shaped plate 361 fixed at the edge of one side of the fixed sleeve 31, a baffle 3610 is fixedly connected to one side of the arc-shaped plate 361, a guide tube 364 is fixedly connected to the middle of the lower surface of the arc-shaped plate 361, a movable tube 368 is sleeved on the outer surface of the guide tube 364, two fixed blocks 367 are evenly fixedly connected to the outer surface of the movable tube 368, second springs 365 are fixedly connected to both sides of the lower surface of the arc-shaped plate 361, a sleeve plate 366 is fixedly connected to the bottom of the second spring 365, an insert block 369 is fixedly connected to the inner bottom of the movable tube 368, a hollow rod 362 is inserted on the outer surface of the insert block 369, and a sealing plug 363 is fixedly connected to the top of the hollow rod 362.

[0053] A rubber ring is provided on the outer surface of the insert block 369 , the top of the hollow rod 362 passes through the interior of the guide tube 364 , and the sleeve plate 366 is sleeved on the outer side of the fixing block 367 .

[0054] The rubber pad on the movable sleeve 33 has a low degree of wear, and the leak-proof component 35 can effectively prevent the outflow of liquid. When the rubber pad is severely worn, the pressure between the rubber pad and the fixed sleeve 31 disappears completely, or even cracks. Continuing to use will cause the loss of liquid, and the lost liquid will cause waste. Therefore, when the liquid inside the storage barrel 1 leaks, the liquid flows to the top of the arc plate 361, enters the interior of the guide cylinder 364, and enters the interior of the movable cylinder 368. The movable cylinder 368 collects the leaked liquid, thereby avoiding the loss of liquid due to the staff's failure to discover it in time. As the liquid inside the movable cylinder 368 increases, the movable cylinder 368 gradually moves downward, driving the hollow rod 362 and the sealing plug 363 to move downward, and the sealing plug 363 seals the top of the guide cylinder 364 At this time, the liquid will stay above the arc plate 361 under the action of the baffle 3610, and continue to collect the liquid. Therefore, from the beginning of the liquid leakage to the time when the liquid inside the movable cylinder 368 is fully collected, the operator can find the liquid leakage as long as possible. When the liquid inside the movable cylinder 368 is removed, the sleeve 366 is moved away from the outside of the fixed block 367, the movable cylinder 368 is removed from the outside of the guide cylinder 364, and the plug block 369 and the hollow rod 362 are separated. During installation, the movable cylinder 368 is sleeved on the guide cylinder 364, and the plug block 369 is inserted on the hollow rod 362 at the same time, and the sealing plug 363 is pushed upward to make the residual liquid on the arc plate 361 flow to the inside of the movable cylinder 368 for continued collection, and the sleeve 366 is re-sleeved on the fixed block 367.

[0055] like Figure 6As shown, the automatic feeding component 4 includes a stirring chamber 41 fixed on the outer surface of the fixed sleeve 31, the lower surface of the stirring chamber 41 is fixedly connected with a connecting pipe 46, the bottom of the stirring chamber 41 is rotatably connected with a transmission rod 42, the outer surface of the transmission rod 42 is fixedly connected with a stirring blade 43, the outer surface of the stirring chamber 41 is fixedly connected with a water pump 44, the inner surface of the connecting pipe 46 is fixedly connected with a support plate 49, the inside of the support plate 49 is rotatably connected with a transverse axis 411, the two sides of the transverse axis 411 are respectively fixedly connected with a second bevel gear 48 and an impeller 410, and the bottom of the transmission rod 42 is fixedly connected with a first bevel gear 47.

[0056] The bottom of the transmission rod 42 extends to the interior of the connecting pipe 46, the first bevel gear 47 and the second bevel gear 48 are meshed with each other, the output end of the water pump 44 extends to the interior of the connecting pipe 46, the interior of the mixing chamber 41 is connected with the interior of the fixed sleeve 31 through the first discharge port 32, and an intermittent control component 45 is provided on the outer surface of the connecting pipe 46.

[0057] The connecting pipe 46 is installed at one end of the tap water pipe, and the other end is connected to the spray pipe. When spraying, when the water flows through the connecting pipe 46, it pushes the impeller 410 to rotate. The rotation of the impeller 410 drives the second bevel gear 48 to rotate. The second bevel gear 48 drives the first bevel gear 47 meshing with it to rotate. The first bevel gear 47 drives the stirring blade 43 to rotate inside the stirring chamber 41 through the transmission rod 42, and stirs and mixes the dust suppressant liquid with a good ratio inside the stirring chamber 41. At the same time, the water pump 44 works to transport the dust suppressant in the stirring chamber 41 to the inside of the connecting pipe 46, and moves to the spray end with the water flow. When the dust suppressant passes through the impeller 410, the impeller 410 rotates, which can stir the dust suppressant and fully merge it with the tap water again, thereby effectively improving the effect of spray dust reduction.

[0058] like Figure 7 and Figure 8 As shown, the intermittent control component 45 includes a mounting cylinder 451 fixed on the outer surface of the mixing chamber 41, a water pump switch 457 is fixedly connected to the inner surface of the mounting cylinder 451 near the top, a circular ring 456 is slidably connected to the inner surface of the mounting cylinder 451, a support shaft 454 is rotatably connected to the bottom of the mounting cylinder 451, an extrusion rod 459 is fixedly connected to the outer surface of the support shaft 454, a pressing plate 458 is fixedly connected to the top of the circular ring 456, a storage plate 4510 is fixedly connected to the inside of the circular ring 456, a third spring 4511 is fixedly connected to one side of the storage plate 4510, a trapezoidal plate 452 is slidably connected to one side of the storage plate 4510, and a transmission component is arranged on the outer surface of the support shaft 454.

[0059] The transmission component includes a gear 455 fixed to the outer surface of the support shaft 454 and the transmission rod 42 , a synchronous belt 453 is sleeved between the two gears 455 , and the extrusion rod 459 is in contact with the oblique edge of the trapezoidal plate 452 .

[0060] While the spray dust suppression is being performed, the water pump 44 works continuously, constantly transporting the liquid in the mixing chamber 41 to the connecting pipe 46, which will cause the dust suppressant in the mixing chamber 41 to be consumed prematurely, resulting in a lack of dust suppressant in the second half of the spray dust suppression, causing the spray dust suppression effect to deteriorate.

[0061] Therefore, when the transmission rod 42 rotates, the gear 455 is driven to rotate. The gear 455 drives another gear 455 to rotate through the synchronous belt 453. The gear 455 drives the extrusion rod 459 to rotate. The extrusion rod 459 contacts the hypotenuse of the trapezoidal plate 452. Due to the action of the third spring 4511, the extrusion rod 459 is pushed by the trapezoidal plate 452 and the ring 456 to rotate inside the mounting cylinder 451. The pressing plate 458 rotates with the ring 456. The pressing plate 458 contacts and squeezes the water pump switch 457. The water pump switch 457 is energized to turn on the water pump 44. At this time, the pressing plate 458 and the ring 456 cannot continue to move, and the support The shaft 454 continues to drive the extrusion rod 459 to rotate, and the extrusion rod 459 slides on the oblique side of the trapezoidal plate 452, pushing the trapezoidal plate 452 toward the inside of the storage plate 4510. When the extrusion rod 459 passes through the trapezoidal plate 452, the pressing plate 458 is no longer subjected to force and is bounced open by the elastic force of the water pump switch 457. During this period, the water pump 44 is powered on and working. When the water pump switch 457 bounces the pressing plate 458 open, the water pump 44 is powered off, so that the water pump 44 is intermittently fed, which can not only save dust suppressants, but also fully utilize the dust suppressants to maximize the effect, thereby avoiding excessive dust suppressants added per unit time, and part of the dust suppressants cannot function and cause waste.

[0062] The specific workflow of the technical solution provided by the present invention is as follows:

[0063] Firstly, by adjusting the position of the piston 37 inside the movable sleeve 33, the volume inside the movable sleeve 33 is changed, so that the dust suppressant of the required concentration can be proportioned according to actual needs, reducing manual proportioning and adding. By setting the movable sleeve 354 inside the feed pipe 311, the feed pipe 311 can be sealed twice, which can not only reduce the pressure inside the storage barrel 1 directly acting on the rubber pad outside the movable sleeve 33, but also improve the sealing performance. By providing the movable cylinder 368, the leaked liquid can be collected to avoid waste.

[0064] Then, the movement of water flow is used as a driving force to drive the impeller 410 to rotate. The impeller 410 drives the transmission rod 42 and the stirring blade 43 to rotate through the transmission to stir the liquid inside the stirring chamber 41. When the dust suppressant enters the water body, it is fully integrated with the tap water under the stirring of the impeller 410 to improve the effect of spray dust reduction. By pressing the water pump switch 457 at intervals, the water pump 44 can be controlled to work intermittently, and the dust suppressant can be added intermittently, which not only effectively saves the dust suppressant, but also makes full use of the dust suppressant.

[0065] The present invention covers any substitution, modification, equivalent method and scheme made on the essence and scope of the present invention. In order to make the public have a thorough understanding of the present invention, specific details are described in detail in the following preferred embodiments of the present invention, but those skilled in the art can fully understand the present invention without the description of these details. In addition, in order to avoid unnecessary confusion about the essence of the present invention, well-known methods, processes, procedures, components and circuits are not described in detail.

[0066] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
