Description

Technical Field

[0001] This utility model relates to the field of mining ventilation duct technology, specifically a multi-channel mining ventilation duct with an installation and fixing structure. Background Technology

[0002] The main functions of mine ventilation ducts are ventilation, dust control, and environmental regulation. Mine ventilation ducts are typically made of high-strength materials such as clinker-coated cloth, rubber-coated cloth, knife-coated cloth, and metal, which possess high wear resistance, compressive strength, and tear resistance to adapt to the complex underground environment. Mine ventilation ducts are available in double-resistant and single-resistant versions. In coal mines, where flammable and explosive gases such as methane are present, double-resistant ventilation ducts are more widely used, effectively reducing the risk of fire and explosion. Existing multi-channel mine ventilation ducts often suffer from poor sealing at the joints, leading to air leakage over time. Furthermore, dust and impurities accumulate inside the ventilation duct over extended periods, affecting its performance and shortening its lifespan. Utility Model Content

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-4 This utility model provides a technical solution: a multi-channel mine ventilation duct with an installation and fixing structure, such as... Figure 1 and Figure 4 As shown, the system includes an air duct assembly 1, which includes a first air duct 11. A second air duct 12 is provided on the right side of the first air duct 11. Both the second air duct 12 and the first air duct 11 are connected to a third air duct 13.

[0022] The first air guide duct 11, the second air guide duct 12, and the third air guide duct 13 are connected in a Y-shape. Steel wire rings are provided on the first air guide duct 11, the second air guide duct 12, the third air guide duct 13, the fourth air guide duct 3, and the fifth air guide duct 5, so as to support the first air guide duct 11, the second air guide duct 12, the third air guide duct 13, the fourth air guide duct 3, and the fifth air guide duct 5.

[0023] In the above scheme, the fluid enters the filter structure 4 through the fifth air guide duct 5 for filtration. The filtered fluid enters the third air guide duct 13 through the second air guide duct 12 and the first air guide duct 11. The fluid enters the fourth air guide duct 3 for air guiding treatment through the limiting installation sealing structure 2 on the third air guide duct 13.

[0024] like Figure 1 and Figure 3 As shown, the air duct assembly 1 connects the fourth air duct 3 and the filter structure 4 through the limiting installation sealing structure 2. The filter structure 4 is located below the fourth air duct 3. The limiting installation sealing structure 2 includes a first sealing component 21. The first sealing component 21 is detached and installed with a second sealing component 22 through a screw 23. The first sealing component 21 includes a first hollow connecting plate 211. A first sealing ring 212 and a limiting protrusion 214 are fixed on the first hollow connecting plate 211. The limiting protrusion 214 is located on both sides of the first sealing ring 212. A sealing ring 213 passes through the first sealing ring 212. The second sealing component 22 includes a second hollow connecting plate 221. A sealing groove 222 and a limiting hole 223 are opened on the second hollow connecting plate 221. A sealing groove 222 is provided between the limiting holes 223.

[0025] The first hollow connecting plate 211 and the second hollow connecting plate 221 are each provided with four sets of threaded holes. The four sets of threaded holes are evenly distributed on the first hollow connecting plate 211 and the second hollow connecting plate 221. A screw 23 passes through the threaded holes on the first hollow connecting plate 211 and the second hollow connecting plate 221. The first hollow connecting plate 211 and the second hollow connecting plate 221 are connected.

[0026] Specifically, there are two sets of limiting protrusions 214. The two sets of limiting protrusions 214 are symmetrically arranged about the central axis of the first hollow connecting plate 211, and the two sets of limiting protrusions 214 correspond to two sets of limiting holes 223.

[0027] In the above scheme, the limiting protrusion 214 on the first hollow connecting plate 211 passes through the limiting hole 223 on the second hollow connecting plate 221, thereby facilitating quick alignment of the threaded holes on the first hollow connecting plate 211 and the second hollow connecting plate 221 in the later stage. When the first hollow connecting plate 211 and the second hollow connecting plate 221 are fitted together, the first sealing ring 212 and the sealing ring 213 pass through and fit into the sealing groove 222 for sealing. The screw 23 passes through the threaded hole on the first hollow connecting plate 211 and the second hollow connecting plate 221, and the nut on the screw 23 is rotated to fix and seal the first hollow connecting plate 211 and the second hollow connecting plate 221.

[0028] like Figure 1 and Figure 2 As shown, the filter structure 4 is connected to the fifth air duct 5 through the limiting installation sealing structure 2. The filter structure 4 includes a filter tube 41, a filter screen 42 is installed inside the filter tube 41, and an auxiliary cleaning component 43 is fixed on the filter screen 42. The auxiliary cleaning component 43 includes a drive source 431, which drives the cleaning brush 432 to rotate and clean the surface of the filter screen 42. A guide groove 433 is provided on the lower side of the filter screen 42. The guide groove 433 passes through the lower side of the filter tube 41, and a sealing cover 434 is threadedly connected to the lower side of the guide groove 433.

[0029] Among them, the external control device controls the drive source 431, which is a motor, and the motor is existing technology.

[0030] Furthermore, the filter screen 42 is provided in two sets, and the two sets of filter screen 42 have different mesh densities;

[0031] A limiting groove is provided on the filter screen 42, and a cleaning brush 432 is slidably connected in the limiting groove; thereby limiting the cleaning brush 432.

[0032] Specifically, there are three sets of material guide troughs 433, which run through the filter tube 41. The observation port of the material guide trough 433 is made of transparent material for easy observation later.

[0033] In the above scheme, the fluid enters the filter tube 41 and the impurities in the fluid are filtered with the assistance of the filter screen 42. With the assistance of the drive source 431, the cleaning brush 432 is driven to rotate. The rotation of the cleaning brush 432 drives the surface of the filter screen 42 to clean. The cleaned impurities fall into the guide trough 433. The rotating sealing cover 434 separates from the guide trough 433, which facilitates the periodic treatment of impurities in the later stage.

[0034] Working principle: When using this multi-channel mine ventilation duct with mounting and fixing structure, the external power supply is turned on, and the fluid is guided by the ventilation duct assembly 1, the fourth ventilation duct 3 and the fifth ventilation duct 5. The sealing effect between the ventilation duct assembly 1, the fourth ventilation duct 3, the filter structure 4 and the fifth ventilation duct 5 is ensured by the setting of the limiting installation sealing structure 2. The impurities and dust in the fluid are treated by the setting of the filter structure 4.
