Description

[0002] In the mining production process, dust suppression is an important environmental protection measure, which aims to reduce the emission of dust, particulate matter and harmful gases generated during mining operations, improve the working environment and reduce the impact on the surrounding environment. At present, a large amount of dust will be raised during the unloading process of ore mining, and mist spraying equipment is usually used for dust suppression.

Secondly, after the small liquid droplets combine with dust particles, it is difficult to centrally process them, resulting in dirty and messy construction sites.

[0042] The present invention is further described in detail below based on the accompanying drawings and embodiments.

[0043] Example 1, please refer to Figures 1 to 4 As shown:

[0044] In order to solve the problems mentioned in the technical solution, the embodiment of the present application provides a complete set of intelligent fog spray dust suppression equipment for mining production, including

[0045] Mobile base 1;

[0046] The wind suction mist spray assembly 3 is arranged on the top surface of the mobile base 1, and the wind suction mist spray assembly 3 includes a dust collecting pipe 31, a negative pressure fan 32 is arranged on the inner side of the air inlet end of the dust collecting pipe 31, the air inlet end of the dust collecting pipe 31 is fixedly connected with a suction nozzle 33, the air outlet end of the dust collecting pipe 31 is fixedly connected with a mixing barrel 34, a first circulation pump 35 is fixedly installed on the top of the mixing barrel 34, and the output end of the first circulation pump 35 is fixedly connected with a mist spray pipe 36, a plurality of mist spray heads 37 are evenly arranged on the upper and lower outer surfaces of the mist spray pipe 36, a corona discharger 38 is arranged on the mist spray head 37, and the inner surface inner wall of the mixing barrel 34 is provided with a vacuum cleaner 35.

A circulation pipe 314 is fixedly connected to the side of the L-shaped dust box 311 away from the connecting pipe 310, and one end of the circulation pipe 314 away from the L-shaped dust box 311 is fixedly connected to the input end of the first circulation pump 35;

[0047] Specifically, the dust is first sucked into the mixing barrel 34 by the negative pressure fan 32, and then sprayed by the mist nozzle 37, so that the dust and the mist spray small liquid droplets are denser and fully combined, which can relatively reduce the consumption of dust suppression liquid. Secondly, the corona discharger 38 is energized to charge the mist spray small liquid droplets, which further facilitates the combination of dust and small liquid droplets. Then, through the setting of the vortex plate 39, the dust and small liquid droplets are spirally descended to improve the effect of the combination of dust and small liquid droplets. Then, after the dust residue is filtered by the filter cylinder 313, the filtered dust suppression liquid can be recycled by the first circulation pump 35.

[0048] A lifter 2, which is arranged between the movable base 1 and the dust collecting pipe 31;

[0049] Specifically, the dust suction height of the suction nozzle 33 can be adjusted by the lifter 2.

[0050] Furthermore, a dust flow detector 315 and a dust charge sensor 316 are provided on the inner side of the air outlet end of the dust collecting pipe 31, and a controller 5 is also provided on the top surface of the mobile base 1, and the first circulation pump 35, the corona discharger 38, the dust flow detector 315, and the dust charge sensor 316 are all electrically connected to the controller 5;

[0051] Specifically, the dust flow rate can be detected by the dust flow detector 315, and after being fed back to the controller 5, the controller 5 controls the first circulation pump 35 to adjust the mist spray volume of the mist nozzle 37. Because different dust particles will carry different charges due to friction, the dust charge sensor 316 can detect whether the dust is charged, as well as the positive and negative charges. After being fed back to the controller 5, the controller 5 selects the positive and negative power of the corona discharger 38, thereby facilitating the combination of dust and dust suppression liquid.

[0052] Preferably, the shape of the suction nozzle 33 is set to be fan-shaped, and the air outlet direction of the dust collecting tube 31 is tangent to the inner wall of the mixing barrel 34.

[0053] Preferably, the portion of the connecting pipe 310 extending from the top surface of the L-shaped dust box 311 and the circulation pipe 314 are both made of flexible materials, and the liquid level in the L-shaped dust box 311 is higher than the top surface of the horizontal part of the inner cavity of the L-shaped dust box 311, and lower than the top surface of the vertical part of the L-shaped dust box 311;

[0054] Specifically, the atomization effect is first used to better wet and settle the dust particles, while increasing the contact area and mixing uniformity between the dust and water, thereby more effectively suppressing the spread of dust.

[0055] For further example 2, please refer to Figures 5 to 11 As shown:

[0056] The L-shaped dust collecting box 311 is provided with a circulating slag discharge component 4 for cleaning the dust slag on the surface of the filter cylinder 313. The circulating slag discharge component 4 includes a collecting port 41 opened on one side of the filter cylinder 313. A second circulating pump 42 is fixedly installed on the top surface of the L-shaped dust collecting box 311. The input end of the second circulating pump 42 is fixedly connected with a slag suction pipe 43. The outer surface of the slag suction pipe 43 away from the end of the second circulating pump 42 is rotatably connected to one end of the filter cylinder 313. A suction nozzle 44 is provided at the end of the slag suction pipe 43 away from the second circulating pump 42. The output end of the second circulating pump 42 is fixedly connected with an output pipe 418. The output pipe 418 is fixedly installed on the L-shaped dust collecting box 311 through a pipe rack 419. A mesh box 420 is provided on the top surface of the vertical part of the L-shaped dust collecting box 311. The bottom of the mesh box 420 is a filter screen structure, which is used to prevent external dust from contaminating the dust suppression liquid in the L-shaped dust collecting box 311, and at the same time, dust slag can be separated from the dust suppression liquid.

[0057] Specifically, the dust suppression liquid and dust residue on the surface of the filter cylinder 313 can be pumped out through the output pipe 418 by the second circulation pump 42 , and screened out through the mesh box 420 .

[0058] Furthermore, two partitions 421 are symmetrically arranged on the inner wall of the net box 420, and the partitions 421 divide the inner side of the net box 420 into three areas, two sides and a middle area, and the liquid outlet of the output pipe 418 is aligned with the middle area;

[0059] Through the above arrangement, the areas on both sides of the partition 421 are used for exhausting the gas in the L-shaped dust box 311 to avoid clogging the net box 420 .

[0060] Furthermore, the filter cylinder 313 can rotate in the sealing body 312, and a tube cylinder 45 is fixedly installed on the side of the L-shaped dust box 311 opposite to the suction nozzle 2 44, and a plug rod 46 is fixedly connected to the axis of the inner cavity of the tube cylinder 45, and a guide rail 47 is provided on the plug rod 46. A push tube 48 is movably inserted between the tube cylinder 45 and the plug rod 46, and a sealing slider 49 is fixedly connected to the inner wall of the push tube 48. The sealing slider 49 can be slidably connected along the inner wall of the guide rail 47. A piston 410 is provided on one side of the push tube 48, and a connecting nozzle 411 is fixedly connected to the plug rod 46. The connecting nozzle 411 is connected to the pressure device, and the pressure between the plug rod 46 and the push tube 48 is changed by the pressure device to realize the extension and retraction of the push tube 48 in the tube cylinder 45. 3 is slidably connected with a slag collecting net 412, a round cover 413 is fixedly connected to the middle part of the slag collecting net 412, a strong spring 414 is connected between the round cover 413 and the push tube 48, a plurality of slide rails 415 are arranged on the inner wall circumference of the round cover 413, a driving block 416 corresponding to the number of the slide rails 415 is arranged on the other side circumference of the push tube 48, and the driving block 416 can be slidably connected in the slide rails 415, the outer surface of the push tube 48 is movably plugged with the side of the filter cylinder 313 away from the slag suction pipe 43, the outer edge of the slag collecting net 412 is provided with a convex edge 417 adapted to the collecting port 41, a water pressure sensor 422 is arranged in the L-shaped dust collecting box 311, and the second circulating pump 42, the pressure device, and the water pressure sensor 422 are all electrically connected to the controller 5;

[0061] Specifically, when a lot of dust residue is screened out on the surface of the filter cylinder 313, the pressure change in the L-shaped dust box 311 can be detected by the water pressure sensor 422, and then the second circulation pump 42 and the pressure device can be controlled by the controller 5 to start, and the dust residue blocked on the surface of the filter cylinder 313 can be automatically cleaned;

[0062] Among them, the pressure device can be selected from one of hydraulic or pneumatic methods. When the push tube 48 rotates, the round cover 413 is driven to rotate through the driving block 416 and the slide rail 415. Through the setting of the strong spring 414, a strong pulling force is maintained between the push tube 48 and the round cover 413 at the initial stage, so that the slag gathering net 412 first drives the filter cylinder 313 to rotate through the convex edge 417 during the movement of the push tube 48, and then the slag gathering net 412 slides in a straight line to scrape the dust on the surface of the filter cylinder 313, and gather the dust to the suction nozzle 44, and finally reverses to recover.

[0063] Preferably, the two sealing bodies 312 are open on one side facing the connecting pipe 310 , so that the dust residue can fully pass through the collecting port 41 and enter the filter cylinder 313 . After the filter cylinder 313 rotates, it can wrap the dust residue together with the sealing body 312 .

[0064] Preferably, the guide rail 47 is composed of twisted segments and straight segments;

[0065] Specifically, the twisted section of the guide rail 47 is used to enable the push pipe 48 to drive the slag gathering net 412 and the filter cylinder 313 to rotate 90 degrees, and the straight section is used to enable the slag gathering net 412 to push the dust slag in a straight line.

[0066] Everything in the above example works like this:

[0067] When in use, negative pressure is generated by the negative pressure fan 32, so that the suction nozzle 33 sucks the dust into the mixing barrel 34 through the dust collecting pipe 31, and then after detection by the dust flow detector 315 and the dust charge sensor 316, the controller 5 controls the first circulation pump 35 and the corona discharger 38, and then the dust suppression liquid is sprayed out in an appropriate amount of charged dust suppression liquid through the mist nozzle 37 through the mist nozzle 36. At the same time, the remaining dust and dust suppression liquid are injected into the L-shaped dust collecting box 311 through the connecting pipe 310. After being filtered by the filter cylinder 313, the air will be discharged through the net box 420 and the dust suppression liquid will be recycled.

[0068] As the filter cylinder 313 is used, the surface will be clogged with dust residue. At this time, the pressure change in the L-shaped dust box 311 detected by the water pressure sensor 422 is controlled by the controller 5 to start the pressure device, so that the push tube 48 extends along the inner surface of the tube cylinder 45. During this process, the sealing slider 49 slides along the guide rail 47, driving the push tube 48 to rotate first and then move in a straight line, and drives the round cover 413, the slag net 412, and the filter cylinder 313 to rotate through the driving block 416, so that the sealing body 312 seals the collection port 41, and then the push tube 48 pushes the slag net 412 to gather the dust residue toward the second suction nozzle 44, and starts the second circulation pump 42 to screen out and process the dust residue on the net box 420, thereby achieving the effect of automatic anti-blocking.
