Description

Technical Field

[0001] This utility model relates to the field of waste gas recovery and treatment technology, and in particular to a waste gas recovery and treatment device for a mesh fabric coating production line. Background Technology

[0002] Fiberglass mesh coating production lines are primarily used to manufacture reinforcing materials, such as fiberglass mesh, by coating their surfaces with specific resins or coatings to improve their physical properties and chemical stability. This process typically includes pretreatment, coating, drying, and curing steps. However, the coating process generates waste gas containing volatile organic compounds (VOCs) and other harmful substances, posing a threat to the environment and human health. Therefore, waste gas recovery and treatment technologies are crucial to addressing this issue.

[0003] The commonly used treatment method involves collecting waste gas through an exhaust system and then introducing it into an activated carbon adsorption unit for purification before discharging it in compliance with standards. However, activated carbon will become saturated over long-term operation, leading to a decrease in treatment efficiency and requiring periodic replacement. Since the adsorption chamber is usually filled with a large amount of granular or honeycomb activated carbon, the loading and unloading process is cumbersome, the operating environment is poor, and the labor intensity is high. Furthermore, the system needs to be shut down during replacement, affecting the continuity and stability of the entire waste gas treatment process.

[0004] Therefore, it is necessary to propose a waste gas recovery and treatment device for a mesh fabric coating production line. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art, this utility model provides a waste gas recovery and treatment device for a mesh cloth coating production line.

[0006] The technical solution is as follows: The waste gas recovery and treatment device of the mesh cloth coating production line includes a support frame, an adsorption chamber, a three-way pipe, a three-way ball valve, a guide plate, a storage frame, and a baffle plate. There are two supports, and an adsorption chamber is set on each of the two supports. A three-way pipe is connected between the same side ends of the two adsorption chambers. A three-way ball valve is installed on each three-way pipe. Multiple sets of guide plates are arranged at intervals in the adsorption chamber. The guide plates are distributed vertically at intervals. A storage frame slides between two vertically opposite guide plates. The storage frame contains an adsorption block. A guide groove with a sliding fit to the corresponding guide plate is opened on the upper and lower sides of the storage frame. A baffle plate is slidably set on the left and right sides of the storage frame.

[0007] Preferably, the device also includes an installation cylinder, a rotating frame, a motor, and a filter cartridge. The installation cylinder is provided, with one end connected to a three-way pipe at the beginning. A rotating frame rotates inside the installation cylinder, and a filter cartridge is installed inside the rotating frame. A motor with its output end connected to the shaft end of the rotating frame is installed on the installation cylinder.

[0008] Preferably, the device also includes a toggle plate and a movable plate. The movable plate is rotatably mounted at the bottom of the mounting cylinder, and the toggle plate is mounted on the inner side of the movable plate to contact and cooperate with the filter cylinder.

[0009] As a preferred embodiment, it also includes an exhaust tower, which is provided and connected to a tee pipe at the tail end.

[0010] As a preferred option, a pick-and-place plate is also included, with each storage box equipped with a pick-and-place plate.

[0011] Preferably, the surface of the filter cartridge is provided with filter cloth along the circumferential direction for filtering particulate impurities.

[0012] The beneficial effects of this utility model are as follows: 1. This utility model adopts a modular adsorption structure and a dual adsorption chamber design. By setting a storage frame with guide grooves and a sliding baffle, and cooperating with the guide plate, the modular installation and quick replacement of adsorption blocks can be realized. This structure can complete the replacement of some adsorption modules without interrupting the operation of the system, effectively reducing the difficulty of operation and labor intensity, and significantly improving the continuity and stability of the waste gas treatment process. At the same time, the dual adsorption chambers are linked with the three-way ball valve for control, which can flexibly switch the operation of single or double adsorption chambers according to the actual working conditions, realize the online replacement of adsorption materials, and ensure the continuous and stable operation of the device.

[0013] 2. This utility model uses a motor-driven rotating frame to rotate the filter cartridge, thereby achieving continuous filtration and separation of particulate matter and impurities in the exhaust gas. At the same time, a toggle plate is provided at the bottom, which periodically taps the surface of the filter cloth during the rotation of the filter cartridge, effectively removing accumulated dust, preventing filter pore blockage, thereby improving filtration efficiency and extending the service life of the filter material, reducing the frequency of manual maintenance, and improving the automation level and operational reliability of the equipment.

Detailed Implementation

[0019] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0020] Example: Waste gas recovery and treatment device for a mesh fabric coating production line, such as Figures 1-3 As shown, the device includes a support frame 1, an adsorption chamber 2, a three-way pipe 3, a three-way ball valve 4, a guide plate 5, a storage frame 6, and a baffle plate 8. Two supports 1 are provided, each supporting an adsorption chamber 2. A three-way pipe 3 connects the two adsorption chambers 2 on the same side. The three-way pipes 3 are symmetrically distributed, creating a gas flow channel between the two adsorption chambers 2. Each three-way pipe 3 is equipped with a three-way ball valve 4, which adopts a T-type structure and is a mature existing valve technology. This valve can flexibly control the opening and closing states of each pipe in the three-way pipe 3, supporting simultaneous operation of one or both adsorption chambers 2, improving the overall flexibility and adaptability of the device. It is particularly suitable for continuous treatment needs under different operating conditions, thereby achieving effective control of the waste gas flow path of the corresponding adsorption chamber 2, and providing a better solution for subsequent operation and maintenance. For convenience, five sets of guide plates 5 are spaced apart inside the adsorption chamber 2. The guide plates 5 are distributed vertically, and a storage frame 6 slides between two opposing guide plates 5. The storage frame 6 contains an adsorption block 9. The upper and lower sides of the storage frame 6 are respectively provided with a guide groove 7 that slides and fits into the corresponding guide plate 5. The design of the guide plate 5 and the guide groove 7 ensures the accurate positioning and smooth sliding of the storage frame 6 during the process of entering and exiting the adsorption chamber 2, avoiding inconvenience or equipment damage caused by positional deviation. At the same time, it enables the modular installation of the storage frame 6 carrying the adsorption block 9, simplifying the replacement process. The adsorption material can be replaced without complicated tools or long downtime, which greatly improves maintenance efficiency and ease of operation. A baffle 8 is slidably provided on the left and right sides of the storage frame 6. The sliding design of the baffle 8 facilitates the quick loading and unloading of the adsorption block 9, enhancing the flexibility and adaptability of the device.

[0021] like Figure 1 and Figure 4As shown, it also includes an installation cylinder 10, a rotating frame 11, a motor 12, and a filter cartridge 13. The installation cylinder 10 is located at the front end of the waste gas treatment process, with one end connected to the first-end tee pipe 3 to receive waste gas drawn in from the production line. The rotating frame 11 rotates inside the installation cylinder 10, and the filter cartridge 13 is installed inside the rotating frame 11. The surface of the filter cartridge 13 is circumferentially covered with filter cloth for filtering particulate impurities, which is used for preliminary filtration of particulate matter and impurities in the waste gas. The motor 12 is installed on the installation cylinder 10, with its output end connected to the shaft end of the rotating frame 11, to drive the rotating frame 11 to rotate the filter cartridge 13, thereby effectively reducing the burden on the subsequent adsorption material (adsorption block 9), extending its service life, and improving the overall purification efficiency.

[0022] like Figure 4 As shown, it also includes a toggle plate 14 and a movable plate 15. The movable plate 15 is rotatably mounted at the bottom of the mounting cylinder 10. The toggle plate 14 is provided on the inner side of the movable plate 15 and contacts and cooperates with the filter cylinder 13. The toggle plate 14 periodically taps the surface of the filter cylinder 13 during rotation, and removes particulate impurities attached to the filter cloth by mechanical vibration. The movable plate 15 serves as a support structure for the toggle plate 14 and can be opened when needed to clean the dust accumulated inside the mounting cylinder 10.

[0023] like Figure 1 As shown, it also includes an emission tower 16, which is connected to a tail-end tee pipe 3 for discharging the purified exhaust gas into the atmosphere in compliance with standards.

[0024] like Figure 3 As shown, it also includes a pick-and-place plate 17. Each of the storage boxes 6 is equipped with a pick-and-place plate 17, which makes it easy for operators to hold and pull out the storage box 6, improving loading and unloading efficiency and ease of use.

[0025] Before use, ensure the entire device is placed stably. During operation, the storage frame 6 can be pulled by holding the pick-and-place plate 17, allowing it to slide smoothly along the guide plate 5, thus removing the storage frame 6 and its components from the adsorption chamber 2. Next, open the corresponding panel, place the required adsorption block 9 into the storage frame 6, and close the panel. Then, push the storage frame 6 containing the adsorption block 9 back into the adsorption chamber 2, easily completing the installation with the help of the guide groove 7 and guide plate 5. Repeat this step to place the adsorption block 9 into the corresponding storage frame 6 as needed. After preparation, connect the installation cylinder 10 to the exhaust system inside the production line and start the exhaust system to allow the waste gas in the production line to be drawn into the installation cylinder 10. At this time, the motor 12 starts working, driving the rotating frame 11 and its filter cartridge 13 to rotate, in order to recover and screen particulate matter and impurities in the waste gas. Next, open the three-way ball valves 4 at both ends to ensure that all flow channels are unobstructed, allowing the exhaust gas to smoothly enter the adsorption chambers 2 on both sides and be purified by the internal adsorption blocks 9 until the exhaust gas meets the emission standards, and is finally discharged through the emission tower 16. This not only improves operating efficiency but also ensures the quality of exhaust gas treatment;

[0026] When it is necessary to replace the adsorption block 9, the three-way ball valve 4 on the corresponding side can be closed first to cut off the airflow channel of the adsorption chamber 2 on that side, allowing the waste gas to continue to be treated through the other adsorption chamber 2, achieving continuous operation. During this period, the adsorption block 9 can be replaced in the storage frame 6 inside the closed adsorption chamber 2 without affecting the overall treatment process. In addition, during the operation of the equipment, as the filter cartridge 13 continues to rotate, its surface filter cloth will periodically contact and slightly impact the actuating plate 14, thereby shaking off the attached impurities, preventing blockage and improving filtration efficiency. Regularly open the movable plate 15 and clean the dust accumulated inside the mounting cylinder 10 to ensure the long-term stable operation of the system.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that variations may 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.
