Description

Technical Field

[0001] This application relates to the field of dust removal equipment technology, and more specifically, to a water mist extraction and dust removal device. Background Technology

[0002] With the continuous advancement of coal mining technology in my country, the scale and complexity of mechanized longwall mining faces have been increasing, and while production efficiency has been significantly improved, the problem of high-concentration dust generated during the mining process has become increasingly serious. The coal dust particles suspended in the underground working environment not only directly threaten the health of miners and are a major cause of pneumoconiosis, but also lead to reduced equipment operating efficiency and increased failure rate. At the same time, they are prone to forming explosive mixtures with air, increasing the risk of coal dust explosions and posing a major threat to mine safety.

[0003] Traditional dust control methods are relatively simple, which limits the application of such devices and makes it difficult to meet the needs of complex underground environments. Summary of the Invention

[0005] This application provides a water mist extraction and dust removal device, including a mounting column, a water mist pipe, an extraction pipe, and a connector. The connector is fixedly mounted on the mounting column. The water mist pipe and the extraction pipe are both mounted on the connector. The connector is provided with two locking components, which are used to lock the water mist pipe or the extraction pipe onto the connector.

[0006] The connector has two mounting holes, through which the water mist pipe and the air extraction pipe pass.

[0007] The locking assembly includes a pressure plate, a screw, and a guide rod. The pressure plate is located in the mounting hole and is movable to abut against the water mist pipe or the air extraction pipe. The screw is threaded through the connector and extends into the mounting hole, and the screw and the pressure plate are rotatably connected by a bearing. The guide rod slides through the connector and extends into the mounting hole, and the guide rod is fixedly connected to the pressure plate.

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0026] Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of the application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0027] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0028] In the description of this application, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product of this application is in use. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on this application. In addition, the terms "first," "second," and "third," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0029] Furthermore, terms such as "horizontal," "vertical," and "sag" do not imply that components must be absolutely horizontal or suspended, but rather that they can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal relative to "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0030] In the description of this application, it should also be noted that, unless otherwise expressly specified and limited, the terms "set up," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0031] like Figures 1 to 3 As shown in the figure, this application provides a water mist extraction and dust removal device, including a mounting column 1, a water mist pipe 2, an extraction pipe 3, and a connector 4. The connector 4 is fixedly mounted on the mounting column 1. The water mist pipe 2 and the extraction pipe 3 are both mounted on the connector 4. The connector 4 is provided with two locking components 5. The corresponding locking components 5 are used to lock and fix the water mist pipe 2 or the extraction pipe 3 on the connector 4.

[0032] With the mounting column 1 serving as the main support, the water mist pipe 2 and the exhaust pipe 3 are integrated onto the connector 4. The water mist pipe 2 sprays water mist to capture dust particles in the air, while the exhaust pipe 3 simultaneously draws in dust-laden air, forming a dust removal system that combines water mist spraying and negative pressure suction, thereby improving dust removal efficiency. Operators can also use water mist dust removal or exhaust dust removal separately to meet different usage needs. In addition, operators can rotate the water mist pipe 2 or the exhaust pipe 3 at will, and then lock the water mist pipe 2 or the exhaust pipe 3 onto the connector 4 using the locking assembly 5, thereby adjusting the spray angle or suction angle and improving the applicability of the device. The connector 4 achieves integrated installation of the water mist pipe 2 and the exhaust pipe 3, simplifying the structure and reducing maintenance costs.

[0033] like Figures 1 to 3 As shown, in this embodiment, the connector 4 has two mounting holes 41, through which the water mist pipe 2 and the air extraction pipe 3 pass.

[0034] The mounting hole 41 on the connector 4 provides a through passage for the water mist pipe 2 and the air extraction pipe 3. After the pipe passes through the mounting hole 41, it is radially pressed and fixed by the locking component 5. The dual-hole independent design avoids interference between pipes. If a single pipe fails, it can be disassembled and replaced separately without affecting the operation of the other pipe.

[0035] like Figures 1 to 3 As shown, in this embodiment, the locking assembly 5 includes a pressure plate 51, a screw 52, ​​and a guide rod 53. The pressure plate 51 is located in the mounting hole 41 and can be moved to abut against the water mist pipe 2 or the air extraction pipe 3. The screw 52 is threaded through the connector 4 and extends into the mounting hole 41. The screw 52 and the pressure plate 51 are rotatably connected by a bearing. The guide rod 53 slides through the connector 4 and extends into the mounting hole 41. The guide rod 53 is fixedly connected to the pressure plate 51.

[0036] When in use, rotating the screw 52 moves the pressure plate 51 to abut against the water mist pipe 2 or the air extraction pipe 3 until the water mist pipe 2 or the air extraction pipe 3 is pressed and fixed in the mounting hole 41; the guide rod 53 and the connecting piece 4 work together to guide and limit the pressure plate 51.

[0037] like Figure 1 and 2 As shown in this embodiment, multiple nozzles 21 are evenly arranged on the water mist pipe 2, and multiple suction nozzles 31 are evenly arranged on the air extraction pipe 3; the multiple nozzles 21 expand the water mist spraying area, and the multiple suction nozzles 31 expand the negative pressure suction area, thereby improving the dust removal efficiency.

[0038] like Figure 1 and 2 As shown in this embodiment, a water inlet pipe 11 and an air outlet pipe 12 are fixedly installed on the mounting column 1, and flexible pipes 13 are connected between the water mist pipe 2 and the water inlet pipe 11, and between the air extraction pipe 3 and the air outlet pipe 12.

[0039] In use, the water inlet pipe 11 is connected to an external water pump. Water flows through the water inlet pipe 11 and the flexible pipe 13 before flowing into the water mist pipe 2. Then, water mist is sprayed from the nozzle 21 to capture dust particles in the air. At the same time, the air extraction pipe 3 is connected to an external exhaust fan. The suction nozzle 31 draws in dusty air, which then enters the air extraction pipe 3 and flows through the flexible pipe 13 and the exhaust pipe 12 for collection and treatment. The flexible pipe 13 can be bent and deformed, allowing the water mist pipe 2 and the air extraction pipe 3 to rotate freely and adjust their angles.

[0040] like Figures 1 to 3 As shown, in this embodiment, the shape of one side of the inner wall of the mounting hole 41 and the shape of the pressure plate 51 are adapted to the shape of the water mist pipe 2 or the shape of the air extraction pipe 3; the inner wall of the mounting hole 41 and the outer wall of the pressure plate 51 are designed to be arc-shaped to match the outer contour of the pipe, thereby increasing the contact area, improving the friction, and preventing the pipe from sliding.

[0041] In this embodiment, the inner wall of the mounting hole 41 and the outer wall of the pressure plate 51 are both provided with anti-slip layers. The anti-slip layers can be made of rubber material, which increases the friction coefficient between the inner wall of the mounting hole 41 and the surface of the pressure plate 51, further improving the stability of pipe installation. Moreover, the rubber material can reduce mechanical damage to the outer wall of the pipe.

[0042] like Figures 1 to 3 As shown, in this embodiment, a handle 54 is fixedly provided at the end of the screw 52 away from the pressure plate 51; the handle 54 makes it easier for the operator to apply force to rotate the screw 52, ​​thus improving the ease of use.

[0043] Working principle: When the water mist and air extraction dust removal device provided in this application is in use, the water inlet pipe 11 is connected to an external water pump. The water flows through the water inlet pipe 11 and the flexible pipe 13 and then into the water mist pipe 2. Subsequently, water mist is sprayed from the nozzle 21 to capture dust particles in the air. At the same time, the air extraction pipe 3 is connected to an external exhaust fan. The suction nozzle 31 draws in dust-laden air and it enters the air extraction pipe 3. After flowing through the flexible pipe 13 and the exhaust pipe 12, it is collected and treated, forming a dust removal system with the synergistic effect of water mist spraying and negative pressure suction, thereby improving dust removal efficiency. Operators can also use water mist dust removal or air extraction dust removal separately to meet different usage needs.

[0044] In addition, the operator can rotate the water mist pipe 2 or the air extraction pipe 3 at will, and then turn the handle 54 to drive the screw 52 to rotate. The screw 52 drives the pressure plate 51 to move to abut against the water mist pipe 2 or the air extraction pipe 3 until the water mist pipe 2 or the air extraction pipe 3 is pressed and fixed in the mounting hole 41, and then the spray angle or suction angle can be adjusted.

[0045] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
