Description

Technical Field

[0001] This utility model belongs to the field of gas extraction technology, and in particular relates to a multi-channel confluence structure for gas extraction. Background Technology

[0002] Methane gas is a general term for toxic and harmful gases, mainly methane (CH4), found in mines. It is commonly known as marsh gas or natural gas. It is colorless, odorless, flammable and explosive, and is one of the main sources of disaster in coal mines. During the mining process, suction pipes connected to fans are usually used to extract methane gas. However, a large amount of dust is easily generated during the methane mining process, which is easily sucked into the pipes. Over time, the dust can accumulate and cause blockages in the pipes. A structure to reduce the amount of dust sucked in is proposed. Utility Model Content

[0003] To address the shortcomings of existing technologies, this invention provides a multi-channel gas extraction confluence structure, which solves the aforementioned problems.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a multi-channel gas extraction confluence structure, comprising a horizontal pipe, a direction-changing component, and a blocking component. Multiple horizontal pipes are horizontally arranged below the suction pipe, and each end of the horizontal pipe is fixedly connected to an inclined pipe A and an inclined pipe B at an angle greater than 45° and less than 90° with respect to the horizontal pipe. The other end of each inclined pipe A is fixedly connected to the suction pipe. The direction-changing component is used to change the direction of airflow within the horizontal pipe. The blocking component is used to block the inclined pipe B.

[0005] Beneficial effects This utility model provides a multi-channel gas extraction confluence structure, which has the following advantages compared with the prior art: 1. When the suction pipe starts to draw gas through the fan, it can simultaneously draw gas from multiple areas because it is equipped with multiple inclined tubes B. During this process, since both inclined tubes B and inclined tube A are inclined at the end of the horizontal pipe, large dust particles in the gas can begin to settle under the action of gravity during the flow of gas into and out of the horizontal pipe. Furthermore, since the horizontal pipe has a certain length, it can effectively increase the settling rate of large dust particles, thereby effectively reducing the probability of dust entering the suction pipe.

Detailed Implementation

[0011] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0012] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0013] Please see Figures 1-4 This utility model provides a multi-channel gas extraction confluence structure, including a horizontal pipe 201, a reversing assembly, and a blocking assembly. Multiple horizontal pipes 201 are horizontally arranged below the suction pipe 101, and inclined pipes A202 and B203 are respectively fixedly connected to both ends of each horizontal pipe 201 at an inclination. The inclination angle between the inclined pipes A202 and B203 and the horizontal pipe 201 is greater than 45° and less than 90°. The other end of each inclined pipe A202 is fixedly connected to the suction pipe 101. A fan 307 is fixedly connected inside the suction pipe 101, and the fan 307 is of type ExdⅠ. The direction-changing component is used to change the direction of airflow in the horizontal tube 201; the blocking component is used to block the inclined tube B203.

[0014] Regarding the above examples, those skilled in the art should know that the implementation of the above technical solutions is not limited to the specific horizontal tube 201 described in the above embodiments. For example, the inner wall of the horizontal tube 201 is provided with a polytetrafluoroethylene anti-stick coating. The purpose of this setting is to avoid dust adhesion.

[0015] In the above embodiment, when the suction pipe 101 starts to suck up gas through the fan 307, it can simultaneously extract gas from multiple areas because it is equipped with multiple inclined pipes B203. During this process, since both the inclined pipes B203 and A202 are inclined at the end of the horizontal pipe 201, large dust particles in the gas can begin to settle under the action of gravity during the process of gas flowing into and out of the horizontal pipe 201. Furthermore, since the horizontal pipe 201 has a certain length, it can effectively increase the settling rate of large dust particles, thereby effectively reducing the probability of dust entering the suction pipe 101.

[0016] Specifically, the reversing assembly includes a semi-circular baffle A204, a semi-circular baffle B205, and a cleaning assembly. The semi-circular baffles A204 and B205 are both vertically fixed in the horizontal tube 201. The semi-circular baffle A204 is above the semi-circular baffle B205, and multiple semi-circular baffles A204 are located between two adjacent semi-circular baffles B205. The height of the semi-circular baffles A204 and B205 is 2 / 3 of the diameter of the horizontal tube 201. The scraping assembly is used to collect settled dust.

[0017] For the above examples, those skilled in the art should know that the implementation of the above technical solutions is not limited to the specific semicircular baffle A204 and semicircular baffle B205 described in the above embodiments. For example, the arc surfaces of the semicircular baffle A204 and semicircular baffle B205 are both in contact with the inner wall of the horizontal tube 201.

[0018] In the above embodiment, because the multiple semicircular baffles A204 and B205 are staggered, the gas can only pass through the gap between itself and the horizontal pipe 201, and is blocked by the adjacent semicircular baffle B205 after passing through. This causes the gas to change direction, while dust particles, due to inertia (and their larger mass), cannot follow the gas's change of direction and eventually collide with and settle on the semicircular baffle B205. Furthermore, because there are multiple semicircular baffles A204 and B205 in the horizontal pipe 201, the dust particles in the gas can be effectively settled at the bottom of the horizontal pipe 201, thereby further increasing the removal effect of dust particles from the gas.

[0019] Specifically, the cleaning and scraping assembly includes a through groove 207. The horizontal tube 201 has a through groove 207 extending to its inner wall on its lower side. An arc plate 206 is provided below the through groove 207. The arc plate 206 is attached to and rotatably disposed on the outer wall of the horizontal tube 201. The lower end face of the semi-circular baffle B205 is attached to the arc surface on the inner side of the arc plate 206.

[0020] Regarding the above examples, those skilled in the art should know that the implementation of the above technical solutions is not limited to the arc plate 206 described in the above embodiments. For example, a damping rubber ring is provided at the connection between the arc plate 206 and the horizontal tube 201. The purpose of this arrangement is to increase the damping of the rotation of the arc plate 206.

[0021] Specifically, a scraper 208 is fixedly connected to one side of the through groove 207, and the lower end face of the scraper 208 is in close contact with the arc surface inside the arc plate 206.

[0022] For the above examples, those skilled in the art should know that the implementation of the above technical solutions is not limited to the specific scraper 208 described in the above embodiments. For example, the scraper 208 is a rubber strip with a certain hardness. The purpose of this setting is to facilitate the increase of the cleaning effect on the dust on the arc plate 206.

[0023] In the above embodiment, after the dust particles settle inside the horizontal pipe 201, since the bottom of the horizontal pipe 201 is arc-shaped, the dust particles can slide onto the arc plate 206. After the gas extraction is stopped, the user can manually rotate the arc plate 206 after sealing the inclined pipe B203 with the sealing component, so that the arc plate 206 gradually stops sealing the through groove 207. At the same time, during this process, since the scraper 208 is attached to the inner arc surface of the arc plate 206, the scraper 208 and the arc plate 206 slide relative to each other during its rotation, so that the inner arc surface of the arc plate 206 can be cleaned by the scraper 208. So that after the arc plate 206 is rotated to 70°, the scraper 208 is at the edge of the arc plate 206, so as to push the dust away from the arc plate 206.

[0024] Specifically, the sealing assembly includes a sealing plate A301, a sealing plate B302, and a sealing component. The sealing plate A301 is fixedly connected to the opening of the inclined tube B203, and the sealing plate B302 is tightly attached to one side of the sealing plate A301. Both the sealing plate A301 and the sealing plate B302 are provided with corresponding through holes 303. The drive assembly is used to make the through holes 303 on the sealing plate A301 and the sealing plate B302 interlock.

[0025] For the above examples, those skilled in the art should know that the implementation of the above technical solutions is not limited to the specific sealing plate A301 described in the above embodiments. For example, the sealing plate A301 has a sealing gasket on the surface for contacting the sealing plate B302, and the through hole 303 penetrates the sealing gasket. The purpose of this arrangement is to facilitate the increase of the sealing effect at the connection point.

[0026] In the above embodiment, when the sealing plate B302 rotates 90° under the action of the driving component, the through holes 303 on the sealing plate A301 and the sealing plate B302 are interlocked, thereby blocking the through holes 303 on the sealing plate A301 and the sealing plate B302, thus blocking the inclined tube B203, so as to stop the extraction of gas in the corresponding area.

[0027] Specifically, the drive assembly includes a connector 209, the sealing plate B302 is fixedly connected to the inner wall of the connector 209, and one side of the connector 209 is rotatably connected to the opening of the inclined tube B203, and a sealing ring is provided at the connection between the connector 209 and the inclined tube B203. The positioning component is used to define the position of the connector 209 on the inclined tube B203.

[0028] In the above embodiment, the user can manually rotate the connector 209, and the sealing plate B302 and sealing plate A301 can rotate relative to each other, thereby blocking the inclined tube B203.

[0029] Specifically, the positioning component includes a bolt 304, which is threaded onto the connector 209. The inclined tube B203 is fixedly provided with a socket A305 corresponding to the end of the bolt 304, and the bolt 304 is inserted into the socket A305. The inclined tube B203 is provided with a socket B306, and the socket B306 and the socket A305 form a 90° angle.

[0030] In the above embodiment, the user can rotate the sealing plate B302 to disengage its end from the socket A305. At this time, the user can freely rotate the connector 209. After the connector 209 is rotated 90°, the end of the bolt 304 is aligned with the socket B306. Then, the user can tighten the bolt 304 to insert its end into the socket B306, thereby preventing the connector 209 from rotating on its own.

[0031] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0032] The term "fixed connection" as used in this application refers to a connection in which parts or components are fixed without any relative movement. This includes both detachable and non-detachable connections.

[0033] (1) Detachable connection: Components are fixed together using screws, splines, wedges, etc. This type of connection allows for disassembly during maintenance without damaging the parts. However, the specifications of the connectors used must be correct. (Such as the length of bolts, keys, and wedges), and tighten them properly.

[0034] (2) Non-removable connections: These mainly refer to welding, riveting, and tenon joints. Since disassembly requires forging, sawing, or oxy-acetylene cutting for repair or replacement, these parts generally cannot be reused. Furthermore, during connection, [the following should be noted]: Pay attention to process quality, technical testing, and remedial measures (such as correction, polishing, etc.).

[0035] The sliding connection referred to in this application means that the component can slide along a linear trajectory, and the hinge referred to in this application means that the component can rotate along an axial constraint.

[0036] In some cases, the sliding connection and hinge referred to in this application may also be damped, enabling the component to maintain in the desired position.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
