Description

Technical Field

[0001] This utility model relates to the field of sewage outlet technology, specifically to a sewage outlet structure for an exhaust gas treatment device. Background Technology

[0002] The exhaust outlet of the exhaust gas treatment device is a facility specifically designed to discharge treated exhaust gas. Its core function is to discharge the purified gas into the environment and convert harmful substances in the exhaust gas into harmless substances such as carbon dioxide, water or nitrogen. However, the existing exhaust outlet structure still has some problems in actual use.

[0003] For example, patent application number CN202123300377.3 relates to a drain port structure for a steam generator, which includes a steam generator body, a connecting part, and a drain port that communicates with the inner cavity of the steam generator body. The outer wall of the connecting part has an external thread, and the axis of the external thread coincides with the axis of the drain port. The connecting part is connected to a drain cover for closing the drain port, and the drain cover has an internal thread. This design improves the opening of the drain port. Most existing drain port structures are simple and generally involve directly connecting an external pipe to the drain port. This operation method can easily cause unstable connection between the external pipe and the drain port, resulting in air leakage.

[0004] To address the aforementioned issues, a wastewater outlet structure for exhaust gas treatment devices is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide a drain outlet structure for an exhaust gas treatment device. By using this device, the problem of existing drain outlet structures being mostly simple and generally involving direct connection of external pipes to the drain outlet is solved. This operation method is prone to causing unstable connection between the external pipes and the drain outlet, resulting in air leakage.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a sewage outlet structure for an exhaust gas treatment device, comprising an exhaust gas treatment device body and a sewage outlet body fixedly connected to the outside of the exhaust gas treatment device body. Multiple sets of sewage outlet bodies are provided. One end of each sewage outlet body is fixedly connected to a connecting box. The connecting box is provided with a fixing structure, which serves to fix external pipes. The fixing structure includes a reduction motor fixedly connected to the top of the connecting box. An inner liner pipe is fixedly connected inside the sewage outlet body.

[0007] Preferably, the output end of the geared motor is fixedly connected to a positive and negative threaded screw, and both ends of the positive and negative threaded screw are threadedly connected to a sliding block, which is slidably connected inside the connecting box.

[0008] With the above-mentioned structure, when the motor starts, the forward and reverse threaded screws can synchronously drive the sliding block connected at both ends to slide in opposite directions along the internal track of the connecting box. This ensures the synchronicity of the movement of the sliding block and prevents it from deviating through the limiting function of the connecting box.

[0009] Preferably, a clamping hoop is fixedly connected to one side of the sliding block, and a rubber pad is provided inside the clamping hoop.

[0010] With the above-mentioned structural design, when the sliding block moves the clamping clamp, the two sets of clamping clamps moving in opposite directions can tightly fit the outer wall of the pipe from both sides, realizing adaptive clamping of pipes of different diameters.

[0011] Preferably, the inner lining tube is slidably connected to a sliding tube, and the sliding tube has an air leakage port, with two sets of air leakage ports.

[0012] With the above-mentioned structural design, the sliding characteristics of the sliding tube inside the inner liner tube can be adjusted according to the changes in air pressure during sewage discharge; the design of two sets of air leakage ports connected to the sewage discharge port body can ensure that the gas discharged from the exhaust gas treatment device body can enter the inner liner tube through the sewage discharge port body.

[0013] Preferably, the air leak is connected to the sewage outlet body, and a spring is fixedly connected inside the inner lining tube.

[0014] The above-mentioned structural design ensures normal gas discharge and provides reset power to prevent backflow: the gas leak is connected to the main body of the drain outlet, directly opening up the gas flow path of the drain outlet body, inner lining pipe, sliding pipe and external pipe, ensuring that the purified gas can be discharged smoothly.

[0015] Preferably, one end of the spring is fixedly connected to a second sliding block, and the second sliding block is fixedly connected to the sliding tube.

[0016] The above-mentioned structure design enables the automatic reset of the sliding tube, thereby blocking gas backflow: the spring force is transmitted to the sliding tube through the second sliding block. When the drain outlet stops venting (gas pressure decreases), the spring releases its elastic potential energy, causing the second sliding block to move closer to the spring. The second sliding block then simultaneously pulls the sliding tube to reset inside the inner liner tube, so that the leak on the sliding tube is hidden inside the inner liner tube again, cutting off the channel for external gas to enter the inner liner tube and preventing waste gas from flowing back to the exhaust gas treatment device and affecting its operation.

[0017] Preferably, one end of the sliding block two is fixedly connected to a protective plate, and the protective plate is slidably connected inside the inner lining tube.

[0018] The above-mentioned structure design can effectively protect the spring and extend its service life: the protective plate and the sliding block are fixed and slidably connected in the inner liner tube. When the gas flows through the inner liner tube, the protective plate can block the dust, impurities and other particles mixed in the gas, and prevent them from adhering to the spring surface, causing the spring to jam, corrode or lose its elasticity.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0020] 1. This application achieves the function of stably fixing the pipe to one side of the sewage outlet body by setting up a geared motor, clamping clamp, positive and negative threaded screws and rubber pads, which improves the use effect of the device and solves the problem that most existing sewage outlet structures are simple and generally directly connect the external pipe to the sewage outlet. This operation method is prone to unstable connection between the external pipe and the sewage outlet, resulting in air leakage.

[0021] 2. This application, through the setting of sliding tube, air vent, spring and sliding block two, achieves the function of preventing external gas from flowing back into the exhaust gas treatment device body, which facilitates use and solves the problem that the existing sewage outlet structure may cause exhaust gas to flow back into the device body during use, thus affecting the operation of the exhaust gas treatment device body.

[0028] 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.

[0029] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings.

[0030] Combination Figures 1-3 The exhaust port structure for the exhaust gas treatment device includes an exhaust gas treatment device body 1 and an exhaust port body 2 fixedly connected to the outside of the exhaust gas treatment device body 1. The exhaust port body 2 is provided with multiple sets. One end of the exhaust port body 2 is fixedly connected to a connection box 21. The connection box 21 is provided with a fixing structure, which serves to fix the external pipe. The fixing structure includes a reduction motor 211 fixedly connected to the top of the connection box 21. An inner liner pipe 22 is fixedly connected inside the exhaust port body 2.

[0031] The present invention will be further described below with reference to the embodiments.

[0032] Example 1:

[0033] To address the problem that most existing sewage outlets have a simple structure, typically directly connecting external pipes to the outlet, which can easily lead to unstable connections and leaks, this embodiment discloses the following technical solution, specifically as follows: Figures 1-3 As shown, a clamping hoop 214 is fixedly connected to one side of the sliding block 213. A rubber pad 215 is provided inside the clamping hoop 214. A sliding tube 221 is slidably connected inside the inner liner tube 22. During use, when exhaust gas is introduced into the exhaust gas treatment device body 1 and a reaction occurs requiring the discharge of other gases, an external pipe can be inserted into the connection box 21. Then, the operator can start the reduction motor 211 located at the top of the connection box 21. The reduction motor 211 drives the positive and negative thread screws 212 to rotate, thereby causing the two sets of sliding blocks 213 to move. The sliding block 213 moves the clamping hoop 214, which in turn clamps the external pipe. The rubber pad 215 inside the clamping hoop 214 improves the connection stability between the clamping hoop 214 and the pipe, so that the sewage outlet body 2 will not leak during the discharge of exhaust gas. When the pipe needs to be removed, the reduction motor 211 is started in reverse, so that the clamping hoop 214 releases its clamp on the pipe and the pipe can be removed. This achieves the function of stably fixing the pipe to one side of the sewage outlet body 2, improving the use effect of the device.

[0034] Example 2:

[0035] To address the issue that existing exhaust outlet structures may experience waste gas backflow during use, causing gas to flow back into the exhaust gas treatment device body 1 during operation and thus affecting its function, this embodiment discloses the following technical solution, specifically as follows: Figure 4 and Figure 5 As shown, the sliding tube 221 has two sets of air vents 222. The air vents 222 are connected to the drain outlet body 2. A spring 223 is fixedly connected inside the inner liner tube 22. One end of the spring 223 is fixedly connected to a sliding block 224, which is fixedly connected to the sliding tube 221. A protective plate 225 is fixedly connected to one end of the sliding block 224, and the protective plate 225 is slidably connected inside the inner liner tube 22. When an external pipe is connected to the drain outlet body 2, because the air pressure inside the inner liner tube 22 is greater than the air pressure inside the pipe, the gas will drive the sliding tube 221 to move, thus allowing the gas to pass through the sliding tube 221. 1. Gas flows out from the inside of the vent 222, allowing gas to enter the pipe. When the gas stops flowing, the sliding block 224 resets under the effect of the spring 223, thereby resetting the sliding tube 221. This keeps the vent 222 inside the inner liner tube 22, preventing external gas from entering the inner liner tube 22 and thus not affecting the normal operation of the device. The protective plate 225 provides protection for the spring 223, preventing impurities in the gas from adhering to the surface of the spring 223 and causing the spring 223 to fail. This achieves the function of preventing external gas from flowing back into the exhaust gas treatment device body 1, making it convenient to use.
