Description

Technical Field

[0001] The utility model relates to the technical field of waste gas transportation, in particular to a waste gas discharge device in a speaker net chemical coating operation room. Background Art

[0002] The speaker mesh chemical coating operation room refers to a workshop or work area specially used for chemical coating of speaker mesh. Speaker mesh chemical coating is a special surface treatment technology, which is usually used to coat metal mesh or other materials to enhance their performance. When performing the speaker mesh chemical coating operation, a large amount of exhaust gas will be generated. The exhaust gas generated needs to be discharged into the exhaust main pipe through the exhaust gas emission device, and then transported to the designated location for treatment by the exhaust main pipe.

[0003] The existing exhaust gas emission device is basically composed of a guide pipe, an arc pipe and a connecting pipe. The connecting pipe is connected to the equipment inside the operating room, and the connecting pipe is connected to the guide pipe through the arc pipe. The guide pipe is connected to the exhaust main pipe on the side away from the arc pipe. The exhaust gas discharged from the horn net chemical coating operating room is transported to the arc pipe through the connecting pipe, and then the exhaust gas is merged into the exhaust main pipe through the guide pipe. However, because the exhaust gas discharged from the horn net chemical coating operating room has strong potential energy, when the exhausted exhaust gas is merged into the exhaust main pipe, it will collide with the gas in the exhaust main pipe, causing turbulence inside the exhaust main pipe, which reduces the exhaust gas transportation efficiency to a certain extent. Utility Model Content

[0004] In response to the shortcomings of the existing technology, the utility model provides an exhaust gas emission device for the horn mesh chemical coating operation room, which solves the problem that the exhaust gas discharged from the horn mesh chemical coating operation room has strong potential energy, resulting in the exhaust gas colliding with the gas in the exhaust manifold when it flows into the exhaust manifold, causing turbulence inside the exhaust manifold, which reduces the exhaust gas transportation efficiency to a certain extent.

[0005] To achieve the above-mentioned object, the present invention provides the following technical solutions: an exhaust gas discharge device for a speaker net chemical coating operation room, comprising a pipeline mechanism, wherein one side of the pipeline mechanism is fixedly provided with an exhaust main pipe communicating therewith;

[0006] The pipeline structure includes a guide pipe, one side of which is fixedly connected to the exhaust main pipe, the guide pipe is communicated with the exhaust main pipe, a partition plate is fixedly provided inside the guide pipe for diverting the internal airflow, the partition plate is fixedly provided with a guide ring on the side adjacent to the exhaust main pipe, and a plurality of inclined guide blocks are fixedly provided inside the guide ring, and the inclination direction of the plurality of guide blocks is the same as the gas flow direction inside the exhaust main pipe.

[0007] As an optimal technical solution of the present invention, a trapezoidal block is provided inside the guide tube, the trapezoidal outer surface is fixedly connected to the inner surface of the guide tube, and the trapezoidal block is located inside the guide tube away from the partition plate.

[0008] As a preferred technical solution of the present invention, a gas conveying component is fixedly provided on the side of the guide pipe away from the exhaust manifold.

[0009] As an optimal technical solution of the present invention, the gas conveying component includes an arc-shaped tube, one side of the arc-shaped tube is fixedly connected to the side of the guide tube away from the exhaust main pipe, the arc-shaped tube is communicated with the guide tube, and a connecting tube is fixedly provided at the bottom of the arc-shaped tube, and the connecting tube is communicated with the arc-shaped tube.

[0010] As a preferred technical solution of the present invention, a guide is fixedly provided inside the arc tube.

[0011] As a preferred technical solution of the present invention, the guide member includes a triangular block, and the triangular block is fixed inside the arc block.

[0012] Compared with the prior art, the present invention provides an exhaust gas discharge device for a speaker net chemical coating operation room, which has the following beneficial effects:

[0013] When the exhaust gas discharged from the horn mesh chemical coating operation room enters the inside of the guide pipe and flows inside the guide pipe, the exhaust gas is separated into two air flows by the partition plate and continues to flow in the guide pipe. When the two air flows are about to enter the exhaust main pipe, the drainage block arranged inside the drainage ring separates the two air flows into multiple small air flows again. At the same time, because the inclination direction of the drainage block is the same as the direction of the air flow inside the exhaust main pipe, the multiple small air flows are stably merged into the exhaust main pipe. The exhaust gas discharged from the horn mesh chemical coating operation room is separated into multiple small air flows by the partition plate and the drainage block, which reduces the potential energy of the exhaust gas discharged from the horn mesh chemical coating operation room, ensures the stability of the exhaust gas when it merges into the exhaust main pipe, and avoids the occurrence of turbulence when merging into the exhaust main pipe due to excessive potential energy of the exhaust gas, thereby improving the exhaust gas transportation efficiency to a certain extent.

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] See also Figure 1-Figure 5 In this embodiment: an exhaust gas emission device for a horn mesh chemical coating operation room comprises a pipeline mechanism, one side of the pipeline mechanism is fixedly provided with an exhaust main pipe 1 communicated with it, the pipeline mechanism comprises a guide pipe 2, one side of the guide pipe 2 is fixedly connected to the exhaust main pipe 1, the guide pipe 2 is communicated with the exhaust main pipe 1, and a partition plate 3 for diverting the internal airflow is fixedly provided inside the guide pipe 2, a diversion ring 4 is fixedly provided on the side of the partition plate 3 adjacent to the exhaust main pipe 1, a plurality of diversion blocks 5 arranged obliquely are fixedly provided inside the diversion ring 4, and the inclination direction of the plurality of diversion blocks 5 is the same as the gas flow direction inside the exhaust main pipe 1, a trapezoidal block 6 is provided inside the guide pipe 2, the trapezoidal outer surface is fixedly connected to the inner surface of the guide pipe 2, and the trapezoidal block 6 is located inside the guide pipe 2 at one end away from the partition plate 3.

[0022] A gas conveying component is fixedly provided on the side of the guide pipe 2 away from the exhaust manifold 1. The gas conveying component includes an arc-shaped pipe 7. One side of the arc-shaped pipe 7 is fixedly connected to the side of the guide pipe 2 away from the exhaust manifold 1. The arc-shaped pipe 7 is communicated with the guide pipe 2. A connecting pipe 8 is fixedly provided at the bottom of the arc-shaped pipe 7. The connecting pipe 8 is communicated with the arc-shaped pipe 7. A guide component is fixedly provided inside the arc-shaped pipe 7. The guide component includes a triangular block 9. The triangular block 9 is fixed inside the arc block.

[0023] When the exhaust gas discharged from the horn mesh chemical coating operation room enters the arc tube 7 through the connecting pipe 8, the exhaust gas is guided by the triangular block 9 inside the arc tube 7. When entering the guide pipe 2, the triangular block 9 guides the flow direction of the exhaust gas, reducing the impact of the exhaust gas on the side wall of the arc tube 7, improving the stability of the exhaust gas when entering the guide pipe 2, and at the same time, to a certain extent, reducing the turbulence caused by the exhaust gas flowing inside the arc block.

[0024] When the partition plate 3 separates the exhaust gas into two air flows and continues to flow in the guide pipe 2, one of the air flows passes through the trapezoidal block 6 set inside the guide pipe 2. Because its flow space gradually shrinks, the frequency of molecular collisions of the exhaust gas increases when it flows through, and the flow rate of the exhaust gas when passing through the trapezoidal block 6 is accelerated. Through this design, the flow rates of the two exhaust gases inside the guide pipe 2 are separated, avoiding the mixing of the two exhaust gases after separation by the guide block 5.

[0025] The working principle and usage process of the present invention: When the exhaust gas discharged from the speaker net chemical coating operation room enters the arc tube 7 through the connecting pipe 8, the exhaust gas is guided by the triangular block 9 inside the arc tube 7 and enters the inside of the guide tube 2. When flowing inside the guide tube 2, the exhaust gas is separated into two air flows by the partition plate 3 and continues to flow in the guide tube 2. When the two air flows are about to enter the exhaust main pipe 1, the drainage block 5 arranged inside the drainage ring 4 separates the two air flows into multiple small air flows again. At the same time, because the inclination direction of the drainage block 5 is the same as the direction of the air flow inside the exhaust main pipe 1, the multiple small air flows are stably merged into the exhaust main pipe 1. The exhaust gas discharged from the speaker net chemical coating operation room is separated into multiple small air flows through the partition plate 3 and the drainage block 5, thereby reducing the potential energy of the exhaust gas discharged from the speaker net chemical coating operation room and ensuring the stability of the exhaust gas when it merges into the exhaust main pipe 1.
