Description

Technical Field

[0001] The invention relates to the technical field of dust removal equipment, in particular to a wet dust and mist gathering and processing device for coal mines. Background Art

[0002] Coal mine wet dust removal mainly achieves the purpose of dust reduction by spraying, spraying droplets into the air, combining with floating dust particles, making the dust particles moist, larger and heavier, and finally settling by gravity, reducing the dust concentration in the air; The existing KCS-450D wet dust collector announced by Huarui Electric in mid-2024 has built-in atomizing equipment, fans, circulating water tanks and sewage pumps. The fan is used to absorb the cold dust air, and the atomizing equipment is used to spray the water in the circulating water tank into atomized form. Under the action of the circulating water tank, the dirt is collected and finally discharged through the sewage pump; however, in order to ensure the dust removal performance of the equipment, the volume of the fan, circulating water tank and pipeline components of the equipment are all set to be larger, so that a larger space is used to place the equipment. There are many inconveniences in the process of moving and transporting, and the flexibility of use in coal mining is poor; The existing application number is CN201710226084.4, which is a wet coal mine dust collector. The patent document discloses a high-speed airflow entraining water mist and mixing with dust, so that the mixture can be collected and captured through a filter. Specifically: by utilizing the airflow flow pattern of the Venturi principle, the gas and dust in the dust collector are captured to complete the dust removal operation. By setting an outer jacket and an atomizing hole, the gas and liquid from the air pressure pipe and the water pressure pipe are atomized to form an atomizing wall in the dust collector shell, and a mixing valve is used to mix the gas in the air pressure pipe and the liquid in the water pressure pipe. The mixed water is transported to the outer jacket and the jet nozzle respectively. At the same time, the jet nozzle sprays out atomized water particle airflow along the radial direction of the shell through the mesh cutting effect of the grid. At this time, a certain negative pressure will be formed near the dust hood opening, and the dust at the dust hood opening will be sucked into the dust collector. At the same time, the dust will contact with the water vapor through the atomizing wall to form a certain free gas-liquid mixture, and will be driven by the airflow of the jet nozzle to move radially into the shell. At this time, the main shaft rotates through the motor, driving the dust catching net to rotate, and the dust in the gas-liquid mixture is captured on the dust catching net in the airflow. However, when using the technical solution in the above-mentioned patent document, in order to maintain the gas-liquid atomization effect, it is necessary to maintain a high air flow rate, so more water is needed, resulting in a large amount of dust-containing sewage being generated during the operation of the equipment, requiring a larger volume of liquid storage tanks and filtrate tanks, resulting in an increase in the volume of the equipment; and, after the dust collecting net has been working for a certain period of time, the pores on its surface will be blocked by dust. In order to ensure continuous operation, it is often necessary to use a steam turbine to drive the dust collecting net to rotate and shake off the dust on its surface, but this will increase the overall volume of the equipment and cause inconvenience in construction operations. Therefore, the present application provides a wet dust and mist aggregation and treatment device for coal mines. Summary of the invention

Since the two dust collection plates are inclined relative to the dust mist treatment cylinder and are parallel to each other, the direction of water mist spraying is opposite to the flow direction of dust mist, which makes the water mist and dust mist fully contact each other; the droplets attached with dust gather at the slag discharge port due to the increase of their own weight, so as to achieve the purpose of dust gathering.

[0027] Embodiment 1: like Figure 1 , Figure 3 , Figure 4 , Figure 8 and Fig.13 As shown, the present embodiment provides a wet dust mist gathering and processing device for coal mines, comprising a plurality of dust mist processing cylinders 211, a flexible cylinder 212 and a fixed cylinder 213 which are rotatably connected to each other; the two ends of the dust mist processing cylinder 211 are respectively connected to the fixed cylinder 213 through the flexible cylinder 212; the fixed cylinder 213 located at the end is connected to the fan, and the fan can use an axial flow fan or a double-suction fan; the upper and lower ends of the dust mist processing cylinder 211 are respectively slidably installed with dust collecting plates 35 parallel to each other, and the flow direction of the dust mist is defined as forward, and a dust mist countercurrent path is formed between the two dust collecting plates 35, and the dust mist processing cylinder 211 is located at the top and bottom of the dust mist countercurrent path. The water inlet 24 and the slag discharge port 25 are respectively provided, and the slag discharge port 25 is correspondingly arranged at the dead angle at the bottom of the dust collecting plate 35 located on the front side, and a misting nozzle 23 is detachably installed in the water inlet 24.

[0028] like Figure 1 and Figure 3As shown, two spherical sleeves with a larger diameter and a smaller diameter are respectively provided at both ends of the dust mist treatment cylinder 211, the flexible sleeve 212 and the fixed sleeve 213. The dust mist treatment cylinder 211, the flexible sleeve 212 and the fixed sleeve 213 are rotatably connected to each other through the spherical sleeves at their ends.

[0029] Among them, the diameter of the filter holes on the dust collecting plate 35 located on the front side is larger than the diameter of the filter holes on the dust collecting plate 35 located on the rear side, and the wall thickness of the dust mist 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 mist treatment cylinder 211, the dust mist treatment cylinder 211 can always be kept in a sealed state.

[0030] like Figure 1 , Figure 3 and Fig.13 As shown, the fixed cylinder 213 is fixedly connected to the inner wall of the coal mine cave through the frame I11, the dust and mist treatment cylinder 211 is movably connected to the inner wall of the coal mine cave through the frame II15, and a lifting seat 16 is provided on the lower side of the frame II15. The two ends of the frame II15 are respectively connected to the lifting seat 16 through a linear electric cylinder 17, and the fixed end and the movable end of the linear electric cylinder 17 are rotatably connected to the frame II15 and the lifting seat 16 respectively. A transverse cylinder 18 is fixedly installed on the lifting seat 16, and the transverse cylinder 18 is sleeved on the outer side of the dust and mist treatment cylinder 211 and is rotatably connected to the dust and mist treatment cylinder 211. A fracture is provided in the middle of the movable cylinder 212, and the fracture divides the movable cylinder 212 into two guide cylinders. The two guide cylinders are connected through a telescopic cylinder 26 and a spring 27. One end of the telescopic cylinder 26 is fixedly connected to the guide cylinder on one side, and the other end of the telescopic cylinder 26 is plug-slidably connected to the guide cylinder on the other side, and the telescopic cylinder 26 is used to conduct the two guide cylinders.

[0031] Start the linear electric cylinder 17 to control the lifting seat 16 and the dust mist treatment cylinder 211 to move vertically downward synchronously relative to the frame II 15, so that the air circulation trajectory of the dust mist treatment cylinder 211 and the inner side of the corresponding joint cylinders 212 on both sides is V-shaped, thereby improving the air flow mode and making the dust mist easier to be captured and processed; 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, and the two guide cylinders on the joint cylinder 212 move toward each other, and the spring 27 is in a relaxed state.

[0032] like Figure 6 and Figure 8 As shown, two annular cavities 181 are provided on the inner side of the transverse cylinder 18, and the two annular cavities 181 are respectively connected to the water inlet 24 and the slag discharge port 25. Two connecting pipes 182 are fixed and connected to the outer side of the transverse cylinder 18 corresponding to the annular cavities 181, and the lower ends of the two connecting pipes 182 are connected to the dust collecting box 41 with the built-in wet filter plate 42 through a corrugated hose.

[0033] like Figure 2 As shown, a water supply pipe 43 and a slag collecting pipe 44 are fixed and connected at both ends of the top of the dust box 41, and a filter element for intercepting dust is provided on the water supply pipe 43. The water supply pipe 43 and the slag collecting pipe 44 are respectively connected with the water inlet 24 and the slag discharge port 25 through the corresponding annular cavity 181 and the connecting pipe 182. A valve is provided 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 provided on the water supply pipe 43, and the lower end of the water supply pipe 43 extends to the upper side of the bottom of the dust box 41.

[0034] The details of using the wet dust mist gathering and processing device of the present application to gather and collect dust mist in the air are as follows: 1. Preparation before use; Multiple dust mist treatment cylinders 211, flexible cylinders 212 and fixed cylinders 213 are arranged according to Fig.13 The lifting seat 16 and the dust mist treatment cylinder 211 are controlled to move vertically downward synchronously relative to the frame Ⅱ15, so that the air circulation trajectory of the dust mist treatment cylinder 211 and the inner side of the corresponding movable cylinders 212 on both sides is V-shaped, thereby improving the air flow mode and making the dust mist easier to be captured and processed.

[0035] 2. The dust and mist are collected in the dust and mist treatment tube 211; First, open the valve and start the water pump, so that the water in the dust collecting box 41 passes through the water supply pipe 43, the corrugated hose, the connecting pipe 182, the annular cavity 181 and the water inlet 24 in sequence, and is sprayed into the dust mist counterflow path through the atomizing nozzle 23. Since the two dust collecting plates 35 are inclined relative to the dust mist treatment cylinder 211 and parallel to each other, the spraying direction of the water mist is opposite to the flow direction of the dust mist, so that the water mist and the dust mist are fully abutted; Afterwards, the droplets with dust attached to them gather at the slag discharge port 25 due to their increased self-weight, thereby achieving the purpose of dust collection. Under the action of gravity, the dust passes through the annular cavity 181, the connecting pipe 182, the corrugated hose and the slag collecting pipe 44 in sequence, enters the dust collecting box 41, and is intercepted by the wet filter plate 42, completing the entire dust collection process.

[0036] 3. Self-cleaning operation; The dust mist treatment cylinder 211 is controlled to rotate back and forth between the two joint cylinders 212, and the dust collecting plate 35 is controlled to slide back and forth on the dust mist treatment cylinder 211; the dust intercepted by the two dust collecting plates 35 is shaken off to realize the self-cleaning function of the equipment.

[0037] In the above step one, the dust mist treatment cylinder 211, the flexible joint cylinder 212 and the fixed cylinder 213 are engaged and rotatably connected with each other through the spherical sleeves at their ends, so that there is a large spatial rotation range between the dust mist treatment cylinder 211, the flexible joint cylinder 212 and the fixed cylinder 213, which can cope with the tortuous coal mining passages and avoid areas prone to collapse, and the safety of the equipment is good; in addition, the diameters of the dust mist treatment cylinder 211, the flexible joint cylinder 212 and the fixed cylinder 213 are limited, and the space requirements for the placement of the equipment are relatively low. The scale of the coal mine excavation tunnel is not restricted by the volume of the equipment, and the operational flexibility of the coal mine excavation operation is relatively high.

[0038] In the above step 2, multiple dust mist treatment cylinders 211 can be operated individually or synchronously according to the amount of dust mist to be treated. When operated individually, the equipment can be maintained without stopping by switching the use positions of the dust mist treatment cylinder 211 and the dust collecting box 41, and the overall stability of the equipment is good; when operated synchronously, multiple groups of atomizing nozzles 23 and dust collecting plates 35 are used to implement multi-stage dust collection operations with high dust removal efficiency; when operated, the vertical position of the dust mist treatment cylinder 211 and the sliding position of the dust collecting plate 35 on the dust mist treatment cylinder 211 are adjusted so that the air flow trajectory of the corresponding dust mist treatment cylinder 211 and the inner side of the corresponding flexible cylinder 212 on both sides is V-shaped, and the dust collecting plate 35 on the inner side of the dust mist treatment cylinder 211 extends toward the inner side of the dust mist treatment cylinder 211, and the dust collecting plate 35 is switched from an idle state to a working state.

[0039] In the process of implementing the above-mentioned scheme of the present application, the number of the dust and mist treatment cylinder 211, the flexible cylinder 212 and the fixed cylinder 213 used can be flexibly adjusted, so that the equipment can be gradually laid out 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, which greatly improves the convenience of construction operations.

[0040] In order to increase the convenience of disassembly between the dust mist treatment cylinder 211, the flexible cylinder 212 and the fixed cylinder 213, as shown in FIG. Fig.12 As shown, the spherical sleeve at the larger diameter end of the dust and mist handling cylinder 211, the flexible cylinder 212 and the fixed cylinder 213 is composed of a plurality of combined spherical cover pieces 22 spliced ​​together; by disassembling and reassembling the plurality of combined spherical cover pieces 22, the dust and mist handling cylinder 211, the flexible cylinder 212 and the fixed cylinder 213 are disassembled and assembled, thereby greatly improving the efficiency of the gradual laying of the equipment as the coal mine excavation operation progresses.

[0041] In this embodiment, the frame I11 is U-shaped, and the frame II15 and the U-shaped frame I11 can be directly connected to the inner wall of the coal mine cave through expansion screws, or installed on pillars against the inner wall of the coal mine cave through fasteners to realize the installation operation of the equipment.

[0042] In this embodiment, for the rotation control of the dust and mist treatment cylinder 211 on the horizontal cylinder 18, a driving motor is installed on the lower side of the lifting seat 16, and a driving wheel is connected to the output shaft of the driving motor. The driving wheel is connected to the transmission pad on the outside of the dust and mist treatment cylinder 211 through friction transmission; the driving motor is started to control the dust and mist treatment cylinder 211 to reciprocate between the two joint cylinders 212; the dust intercepted by the two dust collecting plates 35 is shaken off to realize the self-cleaning function of the equipment.

[0043] In this embodiment, the sliding control of the dust collecting plate 35 on the dust mist treatment cylinder 211 can be implemented by manual control or a hydraulic rod; when the hydraulic rod is used, the extension 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 mist treatment cylinder 211 and the dust collecting plate 35.

[0044] Embodiment 2: The features of this embodiment that are the same as those of the first embodiment are not described in detail.

[0045] Due to the influence of various factors such as the mining process and geological stress, various irregular protrusions will appear on the inner wall of the coal mine. The spatial distribution and shape of these protrusions have a certain degree of randomness and complexity. The above-mentioned scheme of this embodiment can effectively reduce the interference caused by the irregular protrusions on the inner wall of the coal mine to the vertical movement and rotation of the dust and mist treatment cylinder 211.

[0046] By rotating the T-shaped screw 121, the sliding pin 12 is controlled to move horizontally or rotate around its own axis, so that the arc-surface tightening head 13 is in contact with or out of contact with the outer wall of the fixed cylinder 213, which can adapt to the clamping operation of the fixed cylinder 213 with different diameters, or fine-tune the relative position of the fixed cylinder 213 and the frame I11. It can show high operational flexibility under different working conditions and improve the adaptability and reliability of the overall operation of the equipment.

[0047] Embodiment three: The features of this embodiment that are the same as those of the first embodiment are not described in detail. The difference between this embodiment and the first embodiment is that: Figure 8 , Fig. 9 , Fig.10 and Fig.11As shown, in this embodiment, a rotating drum 31 is rotatably installed on the outer side of the horizontal cylinder 18, and the inner edge of the end of the rotating drum 31 abuts against the outer side surface of the dust and mist treatment cylinder 211, and bearings I 34 are respectively provided on the inner sides of the two ends of the rotating drum 31, and bearings II 36 are provided on the ends of the dust collecting plate 35, and a ball-end connecting rod 37 is rotatably connected between the bearings I 34 and II 36.

[0048] like Figure 8 As shown, a driving motor I19 is installed on the lifting seat 16, and the driving motor I19 is shielded by a stopper formed integrally on the top of the lifting seat 16 to prevent the driving motor I19 from being damaged by falling gravel. A driving wheel I is connected to the output shaft of the driving motor I19, and the driving wheel I is connected to the transmission pad I on the outside of the rotating drum 31 through friction transmission; a driving motor II38 is installed in the rotating drum 31, and a driving wheel II is connected to the output shaft of the driving motor II38, and the driving wheel II is connected to the transmission pad II on the outside of the dust and mist treatment drum 211 through friction transmission.

[0049] Start the drive motor I19, control the rotation of the drive wheel I, and utilize the friction transmission between the drive wheel I and the transmission pad I to drive the rotating drum 31 and the drive motor II38 to rotate around the axis of the rotating drum 31; start the drive motor II38, control the rotation of the drive wheel II, and utilize the friction transmission between the drive wheel II and the transmission pad II to drive the dust mist treatment drum 211 and the two dust collecting plates 35 to rotate around the axis of the dust mist treatment drum 211; start the drive motor I19 and the drive motor II38 at the same time to drive the dust mist treatment drum 211 and the rotating drum 31 to rotate synchronously or differentially.

[0050] When the dust mist treatment cylinder 211 and the rotating drum 31 rotate synchronously, on the basis of maintaining the relative position between the dust mist treatment cylinder 211 and the two dust collecting plates 35, the dust mist treatment cylinder 211 is controlled to intermittently reciprocate around its own axis to shake off the dust intercepted by the two dust collecting plates 35, thereby realizing the self-cleaning function of the equipment; during this process, the water inlet 24 and the slag discharge port 25 are respectively connected with the water supply pipe 43 and the slag collecting pipe 44 through the corresponding annular cavity 181 and the connecting pipe 182.

[0051] When the dust mist treatment cylinder 211 and the rotating cylinder 31 rotate differentially, the relative positions of the bearing shell I 34 and the bearing shell II 36 in space are staggered from each other. Under the action of the ball-end connecting rod 37, the two dust collecting plates 35 are synchronously controlled to be inserted or pulled out of the dust mist treatment cylinder 211, and the dust collecting plates 35 in the dust mist treatment cylinder 211 are switched to be in working state or idle state. Compared with the first embodiment, for the movement control method of the dust collecting plates 35, the above-mentioned scheme of this embodiment is used, and the sliding of the dust collecting plates 35 is indirectly controlled by the rotating cylinder 31 and the two ball-end connecting rods 37, so that the synchronous control of the two dust collecting plates 35 can be realized. Since the rotating cylinder 31 is arranged on the outer side of the middle part of the horizontal cylinder 18 and the dust mist treatment cylinder 211, a sealing structure is formed to reduce the impact of foreign objects collision or harsh construction environment on the equipment, thereby ensuring the operation stability of the equipment under complex conditions and the good anti-interference effect of the equipment.

[0052] In order to further enhance the sealing effect of the rotating drum 31 on the horizontal drum 18 and the dust mist treatment drum 211, as shown in FIG. Figure 8 and Fig. 9 As shown, a sealing edge Ⅰ32 for the lifting seat 16 to pass through is provided at the upper end of the rotating drum 31, and a sealing edge Ⅱ33 for the connecting pipe 182 to pass through is provided at the lower end of the rotating drum 31, and the ends of the sealing edge Ⅰ32 and the sealing edge Ⅱ33 are abutted against the outer side surface of the horizontal drum 18, so as to completely seal the outer area of ​​the horizontal drum 18 and the dust and mist treatment drum 211, thereby increasing the protection effect and improving the reliability of the equipment operation.
