Description

Technical Field

[0001] This invention relates to air purification equipment in mines, specifically to a dust removal device for mining. Background Technology

[0002] In the mining working environment, developing effective dust removal devices is of great significance for ensuring the safety of miners and improving the efficiency of mining operations.

[0003] The existing dust removal devices used in mines are basically based on the principle of spraying. They work by squeezing water into atomizing nozzles and spraying it at the dust. When the dust comes into contact with the water mist, it begins to condense into coarser particles and fall off. However, sometimes the dust source in the mine is above, so the water mist needs to be sprayed upwards. This makes it easy for a large number of dust particles to fall down and spread onto the equipment or onto the personnel, which actually increases the dust problem. Summary of the Invention

[0004] The purpose of this section is to outline some aspects of the embodiments of the present invention and to briefly describe some preferred embodiments, specifically: To address the technical problem that existing water mist dust removal devices cannot collect condensed particles, thus easily causing dust pollution when operating in certain directions, this invention provides the following technical solution: A dust removal device for mining, comprising: The liquid extraction path is used to connect to the atomizing end, and the water flows through the liquid extraction path to reach the atomizing end for delivery. The liquid-absorbing end and the separation section are interconnected. The liquid-absorbing end is used to absorb water mist, and the separation section forms a back suction effect and acts on the liquid-absorbing end, and forms a part of the airflow to enter the atomizing end.

[0005] As a preferred technical solution for a mining dust removal device, it also includes a first storage area and a second storage area for storing clean water and filtered water respectively. The first storage area and the second storage area are configured to be alternately connected to the liquid extraction path, and the external water mist enters the second storage area through the liquid extraction end and the separation part in sequence.

[0006] As a preferred technical solution for a mining dust removal device, it also includes a third storage area, where external water mist undergoes solid-liquid separation after passing through the separation section, with the liquid product entering the second storage area and the solid product entering the third storage area.

[0007] As a preferred technical solution for a mining dust removal device, the second storage area is located below the third storage area, and the second storage area and the third storage area are separated by a filter section.

[0008] As a preferred technical solution for a mining dust removal device, it also includes a buffer zone connected to the second storage zone. The separation unit is rotatably disposed in the buffer zone, has a material guiding zone on it, and is connected to the third storage zone. A water permeable section is provided between the material guiding zone and the buffer zone. When the dust-laden water mist enters the material guiding zone, the liquid product passes through the water permeable section and enters the buffer zone under the action of rotation and centrifugation.

[0009] As a preferred technical solution for a mining dust removal device, the separation section has fan blades distributed around the permeable section. When the fan blades are rotating, they generate a suction force from the material guiding area to the buffer area. The permeable section contacts the fan blades and is supported by the fan blades.

[0010] As a preferred technical solution for a mining dust removal device, the material guiding zone is gradually inclined towards the third storage zone.

[0011] As a preferred technical solution for a mining dust removal device, a connecting air passage is configured between the buffer area and the atomizing end.

[0012] As a preferred technical solution for a mining dust removal device, the liquid extraction path includes an extraction chamber configured to alternately communicate with a first storage area or a second storage area. An extraction element is disposed in the extraction chamber and is configured to be connected to the separation section via a transmission connection.

[0013] As a preferred technical solution for a mining dust removal device, the extraction chamber is located between the first storage area and the second storage area, and a valve assembly is configured between the first storage area and the second storage area.

[0014] The dust removal device for mining provided by this invention has the following beneficial effects: 1. This invention utilizes the suction effect of the separation section, combined with the liquid suction end, to collect water mist, that is, to collect dispersed dust particles, thereby reducing the phenomenon of dust spreading to personnel or equipment.

[0015] 2. When the separation unit in this invention is working, it can also centrifuge the collected mud and water through its own structure, thereby separating the water body so that it can be reused when necessary, thus saving water. Attached Figure Description

Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of the present invention.

[0030] Example: This invention provides a dust removal device for mining, the main body of which is as follows: Figure 1 As shown, it has a trolley-type structure equipped with wheels for easy movement within the mine. It also includes an atomizing end and a suction end, which utilize a rotary atomizing nozzle 1 and a collection hood 2, respectively. The collection hood 2 has an annular tubular structure with multiple openings arranged in a ring array to absorb the product (mud) of dust and mist combination in the air. The atomizing nozzle 1 is rotatably positioned in the middle of the collection hood 2 so that both can be lifted synchronously, allowing it to be aimed at the dust removal location during operation. Figure 2 As shown, the rotating nozzle is tilted upwards, and when it is working, it sprays water mist upwards and tilts slightly to the side. After the water mist falls down, it is exactly in the area of ​​the collection hood 2. The main body of the device is equipped with a water tank 3, which is as follows: Figure 3 As shown, the internal structure of water tank 3 is as follows: Figure 4 and Figure 5 As shown, it has multiple isolated spaces inside, which can be divided into a first storage area 4, a second storage area 5, a third storage area 6 and a buffer area 7. It also includes a smaller extraction chamber 8. The extraction chamber 8 is equipped with electrically controlled valves between it and the first storage area 4 and the second storage area 5 distributed on both sides, so that the extraction chamber 8 can be connected to the first storage area 4 or the second storage area 5 respectively. A water pump 9 is also installed in the extraction chamber 8. The outlet of the water pump 9 extends to the outside of the water tank 3 and is connected to the atomizing nozzle 1 through a movable pipe (the structure is not shown in the figure, the same below). Specifically, the first storage area 4 has the largest space and is used to hold clean water; the second storage area 5 is used to hold filtered water; and the third storage area 6 is used to hold dehydrated mud. The third storage area 6 and the second storage area are arranged longitudinally and separated by a removable perforated plate 10 (or foam board). The water tank 3 is equipped with an openable door, which allows the buffer area 7 and the third storage area 6 to be opened for internal cleaning. A separation part 11 is also rotatably mounted on the water tank 3. The structure of the separation part 11 is as follows: Figures 6 to 9 As shown, it is composed of an outer support block 12 and an inner support block 13, which are similar in shape to a windmill. The inner side of the outer support block 12 is conical, that is, the edges of multiple fan blades are on the same conical surface. A conical water-permeable part 14 with a suitable shape is provided at the conical position. The water-permeable part 14 can be a water-permeable structure such as a sponge block. An inclined conical material guiding area 15 is formed between the inner support block 13 and the water-permeable part 14. The bottom of the material guiding area 15 extends into the third storage area 6. The periphery of the outer support block 12 faces the buffer area 7. A connecting nozzle 16 is fixedly installed on the top of the water tank 3. The bottom of the connecting nozzle 16 is rotatably connected to the inner side of the outer support block 12, that is, the connecting nozzle 16 is connected to the material guiding area 15. The top of the connecting nozzle 16 is used to connect to the collection hood 2 through the movable pipe. The top of the buffer area 7 is equipped with a vent 17 for connecting to the outside, so that the air pressure inside the buffer area 7 can be released to the outside, and at least part of the vent 17 is connected to the atomizing nozzle 1 through the movable pipe. Furthermore, the motor shaft on the water pump 9 extends to the top of the water tank 3 and is configured to be connected to the separation part 11 via a transmission element (pulley assembly or gear assembly) so that the water pump 9 drives the separation part 11 to rotate synchronously at high speed when it is working. When the extraction chamber 8 is connected to the first storage area 4, the water pump 9 is immersed in clean water. When the water pump 9 is working, it delivers clean water to the atomizing nozzle 1. The separation section 11 rotates synchronously, and its blades draw the air in the guide area 15 to the periphery. That is, the blades create a suction force from the guide area 15 to the periphery of the separation section 11. Through the connection, the collection hood 2 forms a suction force, and the air drawn into the guide area 15 is thrown into the buffer area 7. That is, the pressure in the buffer area 7 increases. Through the connection... The pressure is sent to the atomizing nozzle 1, thereby providing pressure to the water inside the atomizing nozzle 1 to cooperate with the atomization process of the water and achieve water mist spraying. The excess pressure in the buffer zone 7 is released through the vent 17. The sprayed water mist combines with coal dust to form mud, which is sucked into the collection hood 2 after falling and enters the material guiding zone 15. The suction force draws out the water in the mud and it enters the buffer zone 7 through the permeable part 14. The water flow state at this time is as follows: Figure 9 As shown by the red dashed arrow, centrifugal force further promotes water separation. The slurry, stripped of water, becomes slightly damp mud (which can be understood as sludge), and under centrifugal force, it continues to move towards the conical periphery of the feeding zone 15, i.e., towards the bottom, thus entering the third storage zone 6 and continuously accumulating. The activity state of the mud is as follows: Figure 9 As indicated by the blue dashed arrow; at this point, the entire system enters the operational state, that is, while spraying water mist, it can collect and separate the falling mud. During the above-described operation, the separated water is thrown into the buffer zone 7, which is connected to the second storage zone 5, so that the separated water is finally stored in the second storage zone 5. When the extraction chamber 8 is connected to the second storage zone 5, filtered water can be used for spraying, thereby saving clean water. The operator can determine whether to use clean water or filtered water for spraying according to the situation. Furthermore, the water that seeps out of the mud accumulated in the third storage area 6 can continue to drip through the perforated plate 10 and be stored in the second storage area 5, thereby increasing the water collection effect. Furthermore, a removable filter block 18 can also be installed between the second storage area 5 and the buffer area 7 to further enhance the interception effect of dirt in the separated water. When the filter block 18 gets dirty, it can be replaced by opening the door panel on the water tank 3. Similarly, in this way, the permeable part 14 located on the separation part 11 can also be removed and replaced. The filter block 18 can be made of materials such as sponge. Furthermore, regarding the function of the vent 17, its opening size can be manually adjusted. For example, a gate valve assembly can be installed inside the vent 17 to control its opening degree. Different opening degrees can highlight the working effects of the atomizing nozzle 1 and the collection hood 2 respectively. Specifically, when the opening degree is small, the pressure relief in the buffer zone 7 is not fast enough, so most of the air pressure will enter the atomizing nozzle 1, making the spraying force of the atomizing nozzle 1 greater and the spraying distance farther, thus enabling the device to cover operations in a wider range. When the vent 17 is open to a larger degree, the pressure relief speed is fast, and the pressure inside the buffer zone 7 is closer to normal, making the suction of the separation section 11 smoother, that is, the suction of the airflow is faster, so the suction of the collection hood 2 is stronger and the collection effect is better.

[0031] It should be understood that numerous specific implementation decisions can be made during the development of any practical implementation, such as in any engineering or design project. Such development efforts may be complex and time-consuming, but for those skilled in the art who benefit from this disclosure, the development effort will be a routine work of design, manufacturing, and production without requiring much experimentation.
