Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of drip irrigation tape production equipment, specifically a drip irrigation tape exhaust gas collection device. Background Technology
[0002] Drip irrigation tape is a plastic tubing made of polyethylene and is widely used in agricultural production. Drip irrigation tape is typically cut and granulated or processed into shapes during the extrusion process. This process, whether it's recycling and granulating old drip irrigation tape or manufacturing new tape, generates a significant amount of organic waste gas.
[0003] Existing waste gas collection systems lack effective pressure control mechanisms in their transmission pipelines. During waste gas transmission, unstable internal pressure can lead to leaks or pipeline damage. This not only affects the efficiency of waste gas collection but may also pose safety hazards to the production environment.
[0004] On the other hand, the traditional method for collecting organic waste gas is to use gas collection hoods inside the production workshop. However, this method has some obvious drawbacks. First, setting up waste gas collection and treatment devices inside the workshop occupies workshop space, affecting production efficiency and equipment layout. Second, waste gas treatment devices inside the workshop are prone to causing secondary pollution, adversely affecting the production environment and product quality.
[0005] To address the aforementioned issues, industrial waste gas treatment devices are often installed outside the production workshop. This necessitates a waste gas collection device capable of effectively collecting the production waste gas generated during drip irrigation tape granulation or tape manufacturing and transporting it to an external waste gas treatment facility for processing. However, existing waste gas collection devices still have some shortcomings in practical applications. For example, some waste gas collection devices use vertical cantilever arms for gas collection, but the collection range is limited and cannot meet the needs of large-area waste gas collection. Furthermore, with the increase in the length of the conveying pipeline, the performance requirements for the induced draft fan also increase accordingly, leading to higher industrial costs.
[0006] Therefore, given the limitations and shortcomings of existing technologies, it is necessary to develop a new type of drip irrigation tape exhaust gas collection device. This device should have a larger exhaust gas collection area, higher transmission efficiency, and a more stable pressure control mechanism to meet the needs of exhaust gas collection and treatment during drip irrigation tape production. Summary of the Invention
[0007] To address the shortcomings of existing technologies in the collection of waste gas from drip irrigation tape production, which lacks an effective pressure control mechanism in the gas transmission pipeline, this invention provides a waste gas collection device for drip irrigation tape.
[0008] To solve the above-mentioned technical problems, this utility model provides the following technical solution:
[0009] This utility model discloses a drip irrigation tape exhaust gas collection device, including a base plate, a negative pressure fan fixedly installed at the upper end of the base plate, an air chamber fixedly installed on one side of the negative pressure fan, the air chamber being connected to the exhaust end of the negative pressure fan, and a purification mechanism for purifying exhaust gas being provided in the air chamber.
[0010] A first pipe is connected to and fixedly installed on the air chamber. A pressure relief mechanism is connected to and installed on the first pipe. The pressure relief mechanism is used to reduce the air pressure in the first pipe. A hose is connected to and fixedly installed on the first pipe. The hose passes through the workshop wall and extends to the outside. An adjustment mechanism is installed on the base plate. The adjustment mechanism can adjust the orientation of the negative pressure fan.
[0011] The purification mechanism includes a container, which is fixedly installed in the air chamber. Several evenly distributed air inlet slots are opened on both sides of the container, and the air inlet slots penetrate the container. The container is filled with activated carbon adsorption medium. The pressure relief mechanism includes a connecting pipe, which is fixedly installed on a first pipe. The first pipe is connected to the outside through the connecting pipe. A piston is provided inside the connecting pipe, and a spring is fixedly connected between the piston and the connecting pipe. A T-shaped hole is opened on the piston.
[0012] As a preferred embodiment of this utility model, the air inlet end of the negative pressure fan is provided with a flared structure.
[0013] As a preferred embodiment of this utility model, the adjusting mechanism includes a groove located at the lower end of the base plate. A rotating seat is rotatably mounted at the bottom of the groove. A sliding groove is fixedly mounted on the top of the rotating seat. The sliding groove is a cross-shaped sliding groove. A block is fixedly mounted on the base plate. The block is slidably disposed in the sliding groove. A screw is rotatably mounted on the top of the rotating seat. The upper end of the screw passes through the block and is threadedly connected to the block. A first motor is fixedly mounted inside the rotating seat. The output shaft of the first motor is fixedly connected to the screw.
[0014] As a preferred embodiment of this utility model, rollers are installed at the four corners of the bottom of the tank.
[0015] As a preferred technical solution of this utility model, an incomplete gear ring is fixedly installed on the rotating seat, a movable frame is provided in the groove, and side plates are fixedly installed in the groove on both sides of the movable frame. Two guide rods are fixedly connected between the two side plates and are spaced apart. The guide rods pass through the movable frame.
[0016] As a preferred embodiment of this utility model, an external rack is fixedly installed on the outer side of the movable frame, and the external rack meshes with an incomplete gear ring.
[0017] As a preferred embodiment of this utility model, internal racks are fixedly installed on both sides of the movable frame, a second motor is fixedly installed in the groove, and an incomplete gear is fixedly installed on the output shaft end of the second motor.

[0018] The beneficial effects of this utility model are:
[0019] This type of drip irrigation tape exhaust gas collection device can be flexibly set up according to the workshop site conditions and is suitable for different production conditions. Because the device's location can be set according to the actual layout of the workshop and the exhaust gas emission points, it can more accurately capture exhaust gases and reduce their escape. This flexibility helps optimize the exhaust gas collection path, ensuring that exhaust gases are effectively collected during the emission process, thereby improving the overall exhaust gas treatment efficiency. The flexibly set exhaust gas collection device can be laid out according to the actual situation of the workshop, avoiding occupying excessive production space. Through reasonable planning and layout, the space between the exhaust gas collection device and production equipment can be fully utilized, improving the overall production efficiency of the workshop.
[0020] By adjusting the height of the negative pressure fan to bring it closer to the exhaust source, exhaust gases can be extracted more effectively. This helps reduce the escape and diffusion of exhaust gases and improves the efficiency of exhaust gas collection. The height adjustment of the negative pressure fan can also be optimized according to the distribution of exhaust gases in the workshop, adapting to the exhaust gas emission conditions under different production conditions and ensuring that exhaust gases are collected in a timely and effective manner during the emission process.
[0021] During the waste gas collection process, the device drives the negative pressure fan to swing back and forth, thereby expanding the waste gas collection area. This ensures that the negative pressure fan can cover a wider area, which directly improves the efficiency of waste gas collection. It also eliminates the need to install multiple waste gas collection devices in fixed locations, saves space, and reduces equipment costs and maintenance requirements. Attached Figure Description

[0030] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.
[0031] Example: Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the present invention provides a drip irrigation tape exhaust gas collection device, including a base plate 1, a negative pressure fan 2 fixedly installed on the upper end of the base plate 1, an air chamber 3 fixedly installed on one side of the negative pressure fan 2, the air chamber 3 being connected to the exhaust end of the negative pressure fan 2, and a purification mechanism for purifying exhaust gas being provided inside the air chamber 3.
[0032] A first pipe 4 is connected to and fixedly installed on the air chamber 3. A pressure relief mechanism is connected to and installed on the first pipe 4. The pressure relief mechanism is used to reduce the air pressure in the first pipe 4. A hose 5 is connected to and fixedly installed on the first pipe 4. The hose 5 passes through the workshop wall and extends to the outside. An adjustment mechanism is installed on the base plate 1. The adjustment mechanism can adjust the orientation of the negative pressure fan 2.
[0033] The purification mechanism includes a container 6, which is fixedly installed inside the air chamber 3. Several evenly distributed air inlet slots 7 are provided on both sides of the container 6, and the air inlet slots 7 penetrate the container 6. The container 6 is filled with activated carbon adsorption medium. The pressure relief mechanism includes a connecting pipe 8, which is fixedly installed on the first pipe 4. The first pipe 4 is connected to the outside through the connecting pipe 8. A piston 9 is provided inside the connecting pipe 8, and a spring 10 is fixedly connected between the piston 9 and the connecting pipe 8. A T-shaped hole 11 is provided on the piston 9.
[0034] By placing the device in the workshop, with the negative pressure fan 2 facing the source of the exhaust gas, the fan draws in the exhaust gas and into the air chamber 3. The exhaust gas then passes through the air inlet trough 7 and enters the container 6, where activated carbon purifies it. The purified air is then discharged to the outside through the first pipe 4 and the hose 5. The device can be flexibly set up according to the workshop conditions and is suitable for different production conditions. Because the device's location can be set according to the actual layout of the workshop and the exhaust gas emission point, it can more accurately capture exhaust gas and reduce its escape. This flexibility helps optimize the exhaust gas collection path, ensuring that the exhaust gas is effectively collected during the emission process, thereby improving the overall exhaust gas treatment efficiency. The flexibly set exhaust gas collection device can be laid out according to the actual situation of the workshop, avoiding the occupation of excessive production space. Through reasonable planning and layout, the space between the exhaust gas collection device and the production equipment can be fully utilized, improving the overall production efficiency of the workshop.
[0035] The flexible hose 5, acting as a gas delivery pipeline, can directly reach the outside, eliminating the need for additional gas delivery pipelines and thus improving the efficiency of the device in transmitting waste gas. When the gas pressure inside the first pipe 4 is too high, the delivery burden on the flexible hose 5 increases. Therefore, a pressure relief mechanism is installed to reduce the gas pressure inside the first pipe 4. When the gas pressure inside the first pipe 4 increases to a threshold, the pressure acts on the piston 9 and drives the piston 9 to move outward through the connecting pipe 8. After the piston 9 moves a certain distance, both ends of the T-shaped hole 11 are connected to the outside, and the gas inside the first pipe 4 can be discharged to the outside through the connecting pipe 8 and the T-shaped hole 11, thereby reducing the gas pressure inside the first pipe 4 in a timely manner and alleviating the delivery burden on the flexible hose 5.
[0036] The air inlet of the negative pressure fan 2 is provided with a flared structure 12, which can improve the air intake efficiency of the negative pressure fan.
[0037] The adjustment mechanism includes a groove 13 located at the lower end of the base plate 1. A rotating seat 14 is rotatably mounted at the bottom of the groove 13. A slide groove 15, which is a cross-shaped slide groove, is fixedly mounted on the top of the rotating seat 14. A block 16 is fixedly mounted on the base plate 1 and slidably disposed within the slide groove 15. A screw 17 is rotatably mounted on the top of the rotating seat 14. The upper end of the screw 17 passes through the block 16 and is threadedly connected to the block 16. A first motor 18 is fixedly mounted inside the rotating seat 14, and the output shaft of the first motor 18 is fixedly connected to the screw 17. Rollers 19 are installed at the four corners of the bottom of the groove 13 to facilitate the movement of the pushing device.
[0038] The rotating seat 14 has an incomplete gear ring 20 fixedly mounted on it. A movable frame 21 is located inside the groove 13. Side plates 22 are fixedly mounted on both sides of the movable frame 21 within the groove 13. Two spaced guide rods 23 are fixedly connected between the two side plates 22, passing through the movable frame 21. An external rack 24 is fixedly mounted on the outside of the movable frame 21, meshing with the incomplete gear ring 20. Internal racks 25 are fixedly mounted on both sides inside the movable frame 21. A second motor 26 is fixedly mounted inside the groove 13. An incomplete gear 27 is fixedly mounted on the output shaft of the second motor 26, located inside the movable frame 21 and meshing with the internal racks 25 on both sides.
[0039] By setting the first motor 18 to drive the screw 17 to rotate, the block 16 can be moved along the direction of the slide groove 15, thereby adjusting the height of the base plate 1 and the negative pressure fan 2. When the negative pressure fan 2 collects waste gas, adjusting the height of the negative pressure fan 2 to be closer to the waste gas emission source will more effectively extract the waste gas. This helps to reduce the escape and diffusion of waste gas and improve the waste gas collection efficiency. The height adjustment of the negative pressure fan 2 can also be optimized according to the distribution of waste gas in the workshop, which can adapt to the emission of waste gas under different production conditions and ensure that the waste gas is collected in a timely and effective manner during the emission process.
[0040] The second motor 26 drives the incomplete gear 27 to rotate. The incomplete gear 27 intermittently drives the inner racks 25 on both sides to move, thereby driving the movable frame 21 to move back and forth along the guide rod 23. The outer rack 24 on the movable frame 21 moves back and forth and drives the incomplete gear ring 20 to rotate back and forth, thereby driving the negative pressure fan 2 to swing back and forth.
[0041] During the waste gas collection process, the device drives the negative pressure fan 2 to swing back and forth, thereby expanding the waste gas collection area. This ensures that the negative pressure fan 2 can cover a wider area, which directly improves the efficiency of waste gas collection. It also eliminates the need to install multiple waste gas collection devices in fixed locations, saves space, and reduces equipment costs and maintenance requirements.
[0042] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
