Description

Technical Field

[0001] This utility model relates to the field of waste gas treatment technology, and in particular to a transmission mechanism for waste gas treatment with an adjustment mechanism. Background Technology

[0002] Waste gas often contains harmful substances such as particulate matter, sulfur dioxide, nitrogen oxides, and volatile organic compounds. Common treatment methods include physical treatment, such as using filtration and adsorption to remove particulate matter and some pollutants; chemical treatment, such as converting harmful substances in waste gas into harmless substances through chemical reactions, like using alkaline solutions to absorb sulfur dioxide; and biological treatment, which uses microorganisms to metabolize and decompose organic matter in waste gas. Waste gas treatment is of great significance for protecting the environment, reducing air pollution, ensuring human health and ecological balance, and is an indispensable part of sustainable development. Waste gas is mostly transported through exhaust pipes.

[0003] Existing technologies include, for example, the utility model with publication number CN213467267U. This utility model relates to the field of waste gas treatment, specifically a transmission mechanism for waste gas treatment with an adjustment mechanism. It relates to the field of waste gas treatment technology and includes an exhaust pipe. A dust filter box is fixedly installed at one end of the exhaust pipe. A filter element is movably installed inside the dust filter box. A rack is fixedly installed on one side of the filter element. A first motor is meshed with one side of the rack. One side of the first motor is fixedly installed on the top of the cleaning box. This transmission mechanism for exhaust gas treatment, equipped with an adjustment mechanism, uses a filter element and rack to prevent dust blockage caused by long-term use, which would reduce exhaust efficiency and affect filtration. By installing a cleaning box on one side of the dust filter box, the exhaust gas treatment mechanism has the function of cleaning dust, achieving the effect of cleaning dust, improving the dust filtration efficiency in the exhaust gas, and enhancing the exhaust effect of the exhaust pipe. However, it is difficult to control the flow rate of the exhaust gas during the transportation process. If the exhaust gas flow rate is too high, the residence time of the exhaust gas in the activated carbon bed will be too short, resulting in incomplete adsorption.

[0004] To address the challenge of controlling waste gas flow during transport, where excessive flow leads to insufficient residence time in the activated carbon bed and incomplete adsorption, existing technologies employ secondary filtration. However, this increases operational complexity and consequently results in suboptimal treatment performance. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies, such as difficulty in controlling the flow rate of waste gas during waste gas transportation, and the fact that excessive waste gas flow rate leads to insufficient residence time of waste gas in the activated carbon bed and incomplete adsorption. Therefore, this invention proposes a transmission mechanism for waste gas treatment with an adjustment mechanism.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a transmission mechanism for waste gas treatment with an adjustment mechanism, comprising a pipe body and an adjustment device. A fan is installed on one side of the pipe body, and the adjustment device is disposed on the surface of the pipe body. The adjustment device includes a connecting pipe, which is fixedly connected to the pipe body. A frame is fixedly connected to the surface of the connecting pipe, and a cylinder is fixedly connected to the inner wall of the pipe body. Ventilation holes are opened on the surface of the cylinder, and the cylinder is hollow. By setting the adjustment device, rotating the rocker arm causes the threaded rod to drive the stop block to insert into the cylinder, changing the size of the ventilation holes in the cylinder. This allows for precise control of the waste gas flow rate, ensuring that the waste gas passes through the subsequent treatment process or detection stage at a suitable flow rate, and allowing the waste gas to pass through the activated carbon bed at a suitable speed, thereby improving the adsorption efficiency, ensuring the stability of the treatment effect, and increasing the efficiency of waste gas treatment.

[0007] Preferably, the connecting pipe is connected to the cylinder, and the surface of the frame is threaded with a threaded rod. By setting the threaded rod, when the rocker arm is rotated to make the threaded rod rotate, the threaded rod drives the stop block to insert into the cylinder. In this process, the size of the ventilation hole on the surface of the cylinder can be adjusted by changing the degree to which the stop block is inserted into the cylinder.

[0008] Preferably, a stop block is fixedly connected to the side of the threaded rod closest to the cylinder, and a rocker arm is fixedly connected to the side of the threaded rod furthest from the stop block. By setting the rocker arm, the rotation of the rocker arm drives the threaded rod to rotate, thereby causing the stop block to insert into the cylinder. By changing the degree to which the stop block is inserted into the cylinder, the size of the ventilation holes on the surface of the cylinder can be adjusted.

[0009] Preferably, a sampling device is provided on one side of the pipe body. The sampling device includes a drainage pipe, which is fixedly connected to the pipe body. A threaded sleeve is fixedly connected to the side of the drainage pipe away from the pipe body. A sampling pipe is threadedly connected to the surface of the threaded sleeve. By setting up the sampling device, in the entire waste gas treatment and detection process, the waste gas can be allowed to enter the sampling pipe through the coordinated operation of the first valve and the second valve, so as to achieve effective collection of waste gas. This provides a sample source for subsequent detection work and ensures that there are suitable waste gas samples for analysis.

[0010] Preferably, a first valve is installed on the surface of the drainage pipe, and the drainage pipe is connected to the pipe body. By setting up the drainage pipe, when it is necessary to sample and test the waste gas during the waste gas treatment process, the drainage pipe provides a transfer channel for the waste gas from the pipe body to the sampling pipe by rotating the first valve and the second valve.

[0011] Preferably, a second valve is installed on the surface of the sampling tube, and the sampling tube is connected to the drainage tube. By setting up the sampling tube and rotating the first and second valves, the exhaust gas can enter the sampling tube from the drainage tube, thereby realizing the function of obtaining a sample from the main stream of exhaust gas.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0013] In this invention, by setting up an adjustment device and a sampling device, during use, the fan drives the exhaust gas into the pipe body. Rotating the rocker arm causes the threaded rod to rotate, and simultaneously, the threaded rod rotates, causing a stop block to insert into the cylinder, thus reducing and blocking the ventilation holes on the cylinder surface. The stop block controls the size of the cylinder's ventilation holes, thereby controlling the exhaust gas flow rate. Rotating the first and second valves allows the exhaust gas to enter the sampling tube through the guide pipe. Then, closing the first and second valves and rotating the sampling tube allows it to be removed for easy exhaust gas testing. By using this invention, rotating the rocker arm causes the threaded rod to insert the stop block into the cylinder, changing the size of the cylinder's ventilation holes. This allows for precise control of the exhaust gas flow rate, ensuring that the exhaust gas passes through subsequent treatment processes or testing stages at an appropriate flow rate. It also allows the exhaust gas to pass through the activated carbon bed at a suitable speed, improving adsorption efficiency, ensuring the stability of the treatment effect, and increasing the efficiency of exhaust gas treatment.

[0020] Please see Figure 1-5 This utility model provides a technical solution: a transmission mechanism for exhaust gas treatment with an adjustment mechanism, including a pipe body 1 and an adjustment device 3. A fan 2 is installed on one side of the pipe body 1, and the adjustment device 3 is disposed on the surface of the pipe body 1.

[0021] The specific settings and functions of the adjustment device 3 and the sampling device 4 will be explained in detail below.

[0022] In this implementation scheme: the regulating device 3 includes a connecting pipe 31, which is fixedly connected to the pipe body 1. A frame 36 is fixedly connected to the surface of the connecting pipe 31, and a cylinder 35 is fixedly connected to the inner wall of the pipe body 1. Ventilation holes are opened on the surface of the cylinder 35, and the cylinder 35 is hollow. By setting the regulating device 3, the threaded rod 33 is driven by the rocker arm 34 to insert the stop block 32 into the cylinder 35, thereby changing the size of the ventilation holes in the cylinder 35. This can precisely control the flow rate of the exhaust gas, ensuring that the exhaust gas passes through the subsequent treatment process or detection stage at a suitable flow rate, and allowing the exhaust gas to pass through the activated carbon bed at a suitable speed, which can improve the adsorption efficiency, ensure the stability of the treatment effect, and increase the efficiency of exhaust gas treatment.

[0023] Specifically, the connecting pipe 31 is connected to the cylinder 35, and the surface of the frame 36 is threaded with a threaded rod 33. By setting the threaded rod 33, when the rocker arm 34 is rotated to make the threaded rod 33 rotate, the threaded rod 33 drives the stop block 32 to insert into the cylinder 35. In this process, by changing the degree to which the stop block 32 is inserted into the cylinder 35, the size of the ventilation hole on the surface of the cylinder 35 can be adjusted.

[0024] Specifically, a stop 32 is fixedly connected to the side of the threaded rod 33 near the cylinder 35, and a rocker arm 34 is fixedly connected to the side of the threaded rod 33 away from the stop 32. By setting the rocker arm 34, the rotation of the rocker arm 34 drives the threaded rod 33 to rotate, thereby causing the stop 32 to be inserted into the cylinder 35. By changing the degree to which the stop 32 is inserted into the cylinder 35, the size of the ventilation holes on the surface of the cylinder 35 can be adjusted.

[0025] Specifically, a sampling device 4 is provided on one side of the pipe body 1. The sampling device 4 includes a drainage pipe 41, which is fixedly connected to the pipe body 1. A threaded sleeve 43 is fixedly connected to the side of the drainage pipe 41 away from the pipe body 1. A sampling pipe 44 is threadedly connected to the surface of the threaded sleeve 43. By setting up the sampling device 4, sampling can be carried out in the entire waste gas treatment and detection process.

[0026] In this embodiment, the combined operation of the first valve 42 and the second valve 45 allows the exhaust gas to enter the sampling tube 44, achieving effective collection of the exhaust gas. This provides a sample source for subsequent testing, ensuring that there are suitable exhaust gas samples for analysis.

[0027] Specifically, a first valve 42 is installed on the surface of the drainage tube 41, and the drainage tube 41 is connected to the tube body 1.

[0028] In this embodiment: by setting up a diversion pipe 41, when it is necessary to sample and test the waste gas during the waste gas treatment process, by rotating the first valve 42 and the second valve 45, the diversion pipe 41 provides a transfer channel for the waste gas from the pipe body 1 to the sampling pipe 44.

[0029] Specifically, a second valve 45 is installed on the surface of the sampling tube 44, and the sampling tube 44 is connected to the drainage tube 41.

[0030] In this embodiment: by setting up a sampling tube 44 and rotating the first valve 42 and the second valve 45, the exhaust gas can enter the sampling tube 44 from the diversion tube 41, thereby realizing the function of obtaining a sample from the mainstream of the exhaust gas.

[0031] Working principle: By setting up the regulating device 3 and the sampling device 4, during use, the fan 2 drives the exhaust gas into the pipe body 1. Rotating the rocker arm 34 causes the threaded rod 33 to rotate. Simultaneously, the threaded rod 33 rotates, causing the stop block 32 to insert into the cylinder 35, thus narrowing and blocking the ventilation holes on the surface of the cylinder 35. The size of the ventilation holes in the cylinder 35 is controlled by the stop block 32 to achieve the purpose of controlling the exhaust gas flow. Meanwhile, rotating the first valve 42 and the second valve 45 allows the exhaust gas to enter the sampling pipe 44 through the diversion pipe 41. Then, the first valve 42 is closed. By connecting valve 42 and valve 45 and rotating sampling tube 44, sampling tube 44 can be removed for easy detection of waste gas. By using this invention, rotating rocker arm 34 causes threaded rod 33 to drive stop block 32 into cylinder 35, changing the size of ventilation hole in cylinder 35. This allows for precise control of waste gas flow, ensuring that waste gas passes through subsequent treatment processes or detection stages at a suitable flow rate. It also allows waste gas to pass through activated carbon bed at a suitable speed, improving adsorption efficiency, ensuring the stability of treatment effect, and increasing the efficiency of waste gas treatment.
