Description

Technical Field

[0001] The present invention relates to the technical field of dust removal equipment, and more specifically to a wet dust and fog coalescence treatment device for coal mines. Background Art

[0002] Coal mine wet dust removal mainly achieves the purpose of dust reduction by spraying. The mist droplets are sprayed into the air and combined with the floating dust particles, making the dust particles wet, larger, and heavier, and finally undergoing gravitational settlement to reduce the dust concentration in the air.

[0003] The existing KCS-450D wet dust collector announced by Huarui Electric in the middle of 2024 has an internal atomization device, a fan, a circulating water tank, and a sewage pump. The fan is used to suck cold dust air, and the atomization device is used to atomize and spray the water in the circulating water tank. Under the action of the circulating water tank, the dirt is centrally collected and finally discharged through the sewage pump. However, to ensure the dust removal performance of the equipment, the volumes of the fan, circulating water tank, and pipeline components of the equipment are all set relatively large, so a larger space is required to install the equipment, which brings many inconveniences during the process of moving and handling, and the flexibility of use in coal mine mining is relatively poor.

[0004] There is a wet coal mine dust collector with the application number CN201710226084.4. This patent document discloses a solution in which high-speed airflow entrains water mist and dust for mixing, and the mixture is subjected to dust collection and dust capture through a filter screen. Specifically: by utilizing the airflow flow pattern of the Venturi principle, the gas dust in the dust collector is captured to complete the dust removal operation. The gas-liquid is atomized by setting an outer jacket and atomization holes from the air pressure pipe and the water pressure pipe to form an atomization wall inside the dust collector housing. The gas in the air pressure pipe and the liquid in the water pressure pipe are mixed using a mixing valve and respectively transported to the outer jacket and the ejector nozzle. At the same time, the ejector nozzle sprays out atomized water particle airflow along the radial direction of the housing through the mesh cutting action of the grid. At this time, a certain negative pressure will be formed near the dust suction hood opening, sucking the dust located at the dust suction hood opening into the dust collector. At the same time, the dust will form a certain free gas-liquid mixture when contacting with the water vapor through the atomization wall. Driven by the airflow of the ejector nozzle, it moves radially inside the housing. At this time, the main shaft rotates through the motor, driving the dust-catching net to rotate, and capturing the dust in the gas-liquid mixture during the movement in the airflow on the dust-catching net.

[0005] However, when using the technical solutions in the above patent documents, to maintain the gas-liquid atomization effect, a relatively high air flow rate needs to be maintained, so more water needs to be used, resulting in a large amount of dust-containing sewage generated during the operation of the equipment, and a relatively large-volume liquid storage tank and filtrate tank are required, leading to an increase in the volume of the equipment. Moreover, after the dust-catching net works for a certain period of time, the pores on its surface will be blocked by dust. To ensure continuous operation, a steam turbine is often needed to drive the dust-catching net to rotate and throw off the dust on its surface. However, this will also increase the overall volume of the equipment, causing inconvenience in construction operations. Therefore, the present application provides a wet dust and fog coalescence treatment device for coal mines. Summary of the Invention

[0045] Embodiment 1:

[0046] Such as Figure 1 , Figure 3 , Figure 4 , Figure 8 and Figure 13As shown in the figure, this embodiment provides a wet dust and fog coalescence treatment device for coal mines, which includes a plurality of dust and fog treatment cylinders 211, union cylinders 212 and fixed cylinders 213 that are rotatably connected to each other; both ends of the dust and fog treatment cylinder 211 are respectively connected to the fixed cylinder 213 through the union cylinder 212; the fixed cylinder 213 at the end is connected to a fan, and the fan can be an axial flow fan or a double suction fan; dust collecting plates 35 that are parallel to each other are slidably installed at the upper and lower ends of the dust and fog treatment cylinder 211. Defining the flow direction of the dust and fog as forward, a dust and fog countercurrent path is formed between the two dust collecting plates 35. Water inlets 24 and slag discharge ports 25 are respectively arranged at the top and bottom positions of the dust and fog treatment cylinder 211 in the dust and fog countercurrent path. The slag discharge port 25 is correspondingly arranged at the bottom dead angle of the front-side dust collecting plate 35, and an atomizing nozzle 23 is detachably installed in the water inlet 24.

[0047] As Figure 1 and Figure 3 shown in the figure, two spherical sleeves with different diameters are respectively arranged at both ends of the dust and fog treatment cylinder 211, the union cylinder 212 and the fixed cylinder 213. The dust and fog treatment cylinder 211, the union cylinder 212 and the fixed cylinder 213 are rotationally connected to each other by fitting the spherical sleeves at their own ends.

[0048] Among them, the diameter of the filter holes on the front-side dust collecting plate 35 is larger than the diameter of the filter holes on the rear-side dust collecting plate 35, and the wall thickness of the dust and fog treatment cylinder 211 is larger than the diameter of the filter holes on the dust collecting plate 35, so that after adjusting the sliding position of the dust collecting plate 35 in the dust and fog treatment cylinder 211, the sealing state of the dust and fog treatment cylinder 211 can always be maintained.

[0049] As Figure 1 , Figure 3 and Figure 13 shown in the figure, the fixed cylinder 213 is fixedly connected to the inner wall of the coal mine tunnel through the frame I 11, the dust and fog treatment cylinder 211 is movably connected to the inner wall of the coal mine tunnel through the frame II 15. A lifting seat 16 is arranged on the lower side of the frame II 15. Both ends of the frame II 15 are respectively connected to the lifting seat 16 through linear electric cylinders 17. The fixed end and the movable end of the linear electric cylinder 17 are respectively rotationally connected to the frame II 15 and the lifting seat 16. A horizontal cylinder 18 is fixedly installed on the lifting seat 16. The horizontal cylinder 18 is sleeved outside the dust and fog treatment cylinder 211 and is rotationally connected to the dust and fog treatment cylinder 211. A break is arranged in the middle of the union cylinder 212. The break divides the union cylinder 212 into two guide cylinders. The two guide cylinders are connected by a telescopic cylinder 26 and a spring 27. One end of the telescopic cylinder 26 is fixedly connected to one of the guide cylinders, and the other end of the telescopic cylinder 26 is inserted and slidably connected to the other guide cylinder. The telescopic cylinder 26 is used to conduct the two guide cylinders.

[0050] Start the linear electric cylinder 17, and control the lifting seat 16 and the dust and fog treatment cylinder 211 to move vertically downward synchronously relative to the frame II 15, so that the air flow trajectory inside the dust and fog treatment cylinder 211 and the corresponding inner sides of the two flexible connection cylinders 212 on both sides is in a V shape, improving the air flow mode and making it easier to capture and process the dust and fog. During this process, the fixed end and the movable end of the linear electric cylinder 17 rotate with the frame II 15 and the lifting seat 16 respectively, the two guide cylinders on the flexible connection cylinder 212 move towards each other, and the spring 27 is in a relaxed state.

[0051] As Figure 6 and Figure 8 shown, two annular cavities 181 are arranged inside the horizontal cylinder 18, and the two annular cavities 181 are respectively communicated with the water inlet 24 and the slag discharge port 25. Two communicating pipes 182 are fixedly and communicatively arranged outside the horizontal cylinder 18 corresponding to the annular cavities 181. The lower ends of the two communicating pipes 182 are communicated with the dust collecting box 41 with an internal wet filter plate 42 through corrugated hoses.

[0052] As Figure 2 shown, at both ends of the top of the dust collecting box 41, a water supply pipe 43 and a slag collecting pipe 44 are respectively fixedly and communicatively arranged. A filter element for intercepting dust and slag is arranged on the water supply pipe 43. The water supply pipe 43 and the slag collecting pipe 44 are respectively communicated with the water inlet 24 and the slag discharge port 25 through the corresponding annular cavities 181 and communicating pipes 182. A valve is arranged on the slag collecting pipe 44, and the valve uses a wireless control valve or an Internet of Things electric valve. A water pump is arranged on the water supply pipe 43, and the lower end of the water supply pipe 43 extends towards the upper side of the bottom of the dust collecting box 41.

[0053] The details of using the wet dust and fog coalescence treatment device of the present application to collect and treat the dust and fog in the air are as follows:

[0054] I. Preparation before use;

[0055] Connect multiple dust and fog treatment cylinders 211, flexible connection cylinders 212 and fixed cylinders 213 together one by one in the Figure 13 state, and install them on the side of the inner wall of the coal mine tunnel through the frame I 11 and the frame II 15; control the lifting seat 16 and the dust and fog treatment cylinder 211 to move vertically downward synchronously relative to the frame II 15, so that the air flow trajectory inside the dust and fog treatment cylinder 211 and the corresponding inner sides of the two flexible connection cylinders 212 on both sides is in a V shape, improving the air flow mode and making it easier to capture and process the dust and fog.

[0056] II. Dust and fog perform dust collection operations inside the dust and fog treatment cylinder 211;

[0057] First, open the valve and start the water pump, so that the water in the dust collection box 41 sequentially passes through the water supply pipe 43, the corrugated hose, the connecting pipe 182, the annular cavity 181, and the water inlet 24, and is sprayed into the dust mist countercurrent path through the atomizing nozzle 23. Since the two dust collection plates 35 are inclined relative to the dust mist treatment cylinder 211 and are parallel to each other, the direction of the water mist spray is opposite to the flow direction of the dust mist, promoting the full contact between the water mist and the dust mist;

[0058] After that, the droplets attached with dust gather at the slag discharge port 25 due to the increase in their own weight, achieving the purpose of dust collection. Under the action of gravity, the dust residue sequentially passes through the annular cavity 181, the connecting pipe 182, the corrugated hose, and the slag collection pipe 44, enters the dust collection box 41, and is intercepted by the wet filter plate 42, completing the entire dust residue collection process.

[0059] III. Self-cleaning operation;

[0060] Control the dust mist treatment cylinder 211 to reciprocally rotate between the two union cylinders 212, and the dust collection plate 35 to reciprocally slide on the dust mist treatment cylinder 211; shake off the dust intercepted by the two dust collection plates 35 to achieve the self-cleaning function of the equipment.

[0061] In the above step I, the dust mist treatment cylinder 211, the union cylinder 212, and the fixed cylinder 213 are rotationally connected to each other by spherical sleeves at their own ends, so that there is a large range of rotational space between the dust mist treatment cylinder 211, the union cylinder 212, and the fixed cylinder 213, which can cope with the tortuous coal mining tunnels and avoid the areas prone to collapse, and the safety of equipment use is good; in addition, the diameters of the dust mist treatment cylinder 211, the union cylinder 212, and the fixed cylinder 213 are limited, the requirements for the placement space of the equipment are low, the scale of the coal mine excavation tunnel is not restricted by the volume of the equipment, and the operation flexibility of the coal mine excavation operation is relatively high.

[0062] In the above step II, according to the amount of dust mist to be treated, multiple dust mist treatment cylinders 211 can be operated separately or synchronously. When operating separately, by switching the use positions of the dust mist treatment cylinder 211 and the dust collection box 41, the non-stop maintenance of the equipment can be realized, and the overall use stability of the equipment is good; when operating synchronously, multi-stage dust collection operations are implemented by using multiple groups of atomizing nozzles 23 and dust collection plates 35, and the dust removal efficiency is high; during operation, adjust the vertical position of the dust mist treatment cylinder 211 and the sliding position of the dust collection plate 35 on the dust mist treatment cylinder 211, so that the air flow trajectory inside the corresponding dust mist treatment cylinder 211 and the inner sides of the two corresponding union cylinders 212 is in a V shape, and the dust collection plate 35 inside the dust mist treatment cylinder 211 extends towards the inside of the dust mist treatment cylinder 211, switching the dust collection plate 35 from the idle state to the working state.

[0063] In the process of implementing the above solutions of this application, the usage quantities of the dust and fog treatment cylinder 211, the union joint cylinder 212, and the fixed cylinder 213 can be flexibly adjusted, enabling the equipment to be gradually laid as the coal mine excavation operation progresses. Compared with traditional large-scale dust reduction equipment, there is no need to repeatedly move the entire equipment, greatly improving the convenience of construction operations.

[0064] To increase the disassembly convenience between the dust and fog treatment cylinder 211, the union joint cylinder 212, and the fixed cylinder 213, as Figure 12 shown, the spherical sleeves at the larger-diameter ends of the dust and fog treatment cylinder 211, the union joint cylinder 212, and the fixed cylinder 213 are composed of a plurality of combined spherical cover sheets 22 spliced with each other; by disassembling and recombining the plurality of combined spherical cover sheets 22, the disassembly and assembly operations of the dust and fog treatment cylinder 211, the union joint cylinder 212, and the fixed cylinder 213 are implemented, greatly improving the efficiency of the equipment being gradually laid as the coal mine excavation operation progresses.

[0065] In this embodiment, the frame Ⅰ 11 is U-shaped, and the frame Ⅱ 15 and the U-shaped frame Ⅰ 11 can be directly connected to the inner wall of the coal mine tunnel through expansion screws, or installed on the struts against the inner wall of the coal mine tunnel through fasteners to achieve the installation operation of the equipment.

[0066] In this embodiment, for the rotation control of the dust and fog treatment cylinder 211 on the horizontal cylinder 18, a driving motor is installed on the lower side of the lifting seat 16, a driving wheel is connected to the output shaft of the driving motor, and the driving wheel is frictionally connected to the transmission pad on the outer side of the dust and fog treatment cylinder 211; the driving motor is started to control the dust and fog treatment cylinder 211 to reciprocally rotate between the two union joint cylinders 212; the dust intercepted by the two dust collecting plates 35 is shaken off to achieve the self-cleaning function of the equipment.

[0067] In this embodiment, for the sliding control of the dust collecting plate 35 on the dust and fog treatment cylinder 211, it can be controlled manually or by a hydraulic rod; when using the hydraulic rod, the extending direction of the hydraulic rod is parallel to the sliding direction of the dust collecting plate 35, and the fixed end and the movable end of the hydraulic rod are respectively connected to the dust and fog treatment cylinder 211 and the dust collecting plate 35.

[0068] Embodiment 2:

[0069] The features identical to those of Embodiment 1 in this embodiment will not be described in detail. The different solution of this embodiment from Embodiment 1 is as follows: As Figure 5As shown in the figure, in this embodiment, sliding grooves 14 are respectively arranged at the upper and lower ends of the frame I 11. A sliding pin 12 is slidably installed in the sliding groove 14. The sliding pin 12 is position-locked with the frame I 11 through a T-shaped screw 121. An arc-shaped pressing head 13 is fixedly installed on the side of the sliding pin 12. The end of the arc-shaped pressing head 13 abuts against the outer side surface of the fixed cylinder 213, so that a certain distance can be maintained between the fixed cylinder 213 and the inner wall of the coal mine tunnel.

[0070] Due to various factors such as the mining process and geological stress, various irregular convex structures will appear on the inner wall of the coal mine tunnel. The distribution and shape of these convexities in space have a certain degree of randomness and complexity. Using the above scheme of this embodiment can effectively reduce the interference caused by the irregular convexities on the inner wall of the coal mine tunnel to the vertical movement and rotation of the dust and fog treatment cylinder 211.

[0071] Rotate the T-shaped screw 121 to control the horizontal movement of the sliding pin 12 or rotate around its own axis, so that the arc-shaped pressing head 13 abuts against or disengages from the outer side wall of the fixed cylinder 213, adapting to the clamping operation of the fixed cylinder 213 with different diameters, or finely adjusting the relative position between the fixed cylinder 213 and the frame I 11, which can show high operation flexibility under different working conditions and improve the adaptability and reliability of the overall operation of the equipment.

[0072] Embodiment Three:

[0073] The features that are the same as those in Embodiment One will not be described in detail. The different scheme in this embodiment from Embodiment One is as follows: As Figure 8 、 Figure 9 、 Figure 10 and Figure 11 shown, in this embodiment, a rotating cylinder 31 is rotatably installed on the outside of the horizontal cylinder 18. The inner edge of the end of the rotating cylinder 31 abuts against the outer side surface of the dust and fog treatment cylinder 211. Axle bushings I 34 are respectively arranged on the inner sides of both ends of the rotating cylinder 31. Axle bushings II 36 are arranged at the ends of the dust collecting plate 35. A spherical end connecting rod 37 is rotatably connected between the axle bushings I 34 and the axle bushings II 36.

[0074] As Figure 8 shown, a driving motor I 19 is installed on the lifting seat 16. The driving motor I 19 is shielded by the integrally formed retaining edge at the top of the lifting seat 16 to prevent damage to the driving motor I 19 caused by falling gravel. A driving wheel I is connected to the output shaft of the driving motor I. The driving wheel I is frictionally connected to the transmission pad I on the outside of the rotating cylinder 31; a driving motor II 38 is installed in the rotating cylinder 31. A driving wheel II is connected to the output shaft of the driving motor II. The driving wheel II is frictionally connected to the transmission pad II on the outside of the dust and fog treatment cylinder 211.

[0075] Start the drive motor Ⅰ 19, control the rotation of the drive wheel Ⅰ, and drive the rotating cylinder 31 and the drive motor Ⅱ 38 to rotate about the axis of the rotating cylinder 31 by means of frictional transmission between the drive wheel Ⅰ and the transmission pad Ⅰ; start the drive motor Ⅱ 38, control the rotation of the drive wheel Ⅱ, and drive the dust and fog treatment cylinder 211 and the two dust collecting plates 35 to rotate about the axis of the dust and fog treatment cylinder 211 by means of frictional transmission between the drive wheel Ⅱ and the transmission pad Ⅱ; start the drive motor Ⅰ 19 and the drive motor Ⅱ 38 simultaneously to drive the dust and fog treatment cylinder 211 and the rotating cylinder 31 to rotate synchronously or differentially.

[0076] When the dust and fog treatment cylinder 211 and the rotating cylinder 31 rotate synchronously, on the basis of maintaining the relative positions between the dust and fog treatment cylinder 211 and the two dust collecting plates 35, control the dust and fog treatment cylinder 211 to perform intermittent reciprocating rotation about its own axis, shake off the dust intercepted by the two dust collecting plates 35, and realize the self-cleaning function of the device; during this process, the water inlet 24 and the slag discharge port 25 are respectively kept in communication with the water supply pipe 43 and the slag collecting pipe 44 through the corresponding annular cavity 181 and the communication pipe 182.

[0077] When the dust and fog treatment cylinder 211 and the rotating cylinder 31 rotate differentially, the relative positions of the bearing bush Ⅰ 34 and the bearing bush Ⅱ 36 in space are staggered from each other. Under the action of the spherical end connecting rod 37, synchronously control the two dust collecting plates 35 to be inserted into or pulled out of the dust and fog treatment cylinder 211, and switch the dust collecting plates 35 in the dust and fog treatment cylinder 211 to the working state or the idle state; compared with the control method of the movement of the dust collecting plate 35 in the first embodiment, using the above scheme of this embodiment, the indirect control of the sliding of the dust collecting plate 35 is realized through the rotating cylinder 31 and the two spherical end connecting rods 37, the synchronous control of the two dust collecting plates 35 can be realized, and because the rotating cylinder 31 is arranged on the outer side of the middle part of the horizontal cylinder 18 and the dust and fog treatment cylinder 211 to form a sealed structure, the influence of external object collision or harsh construction environment on the device is reduced, the operation stability of the device under complex conditions is ensured, and the anti-interference effect of the device is good.

[0078] To further increase the sealing effect of the rotating cylinder 31 on the horizontal cylinder 18 and the dust and fog treatment cylinder 211, as Figure 8 and Figure 9 shown, a sealing edge Ⅰ 32 through which the lifting seat 16 penetrates is provided at the upper end of the rotating cylinder 31, and a sealing edge Ⅱ 33 through which the communication pipe 182 penetrates is provided at the lower end of the rotating cylinder 31. The ends of the sealing edge Ⅰ 32 and the sealing edge Ⅱ 33 are abutted against the outer side surface of the horizontal cylinder 18 to completely seal the outer area of the horizontal cylinder 18 and the dust and fog treatment cylinder 211, increase the protection effect, and improve the reliability of the device operation.
