Description

Technical Field

[0001] This utility model relates to the field of waste gas treatment technology, and in particular to a waste gas recovery and treatment device for aluminum alloy smelting furnaces. Background Technology

[0002] To reduce air pollution, waste gas treatment devices are becoming increasingly common. These devices can reduce the levels of harmful substances in industrial waste gas, ensuring that the gas meets emission standards before being released into the environment, thus reducing the factory's pollution to the environment.

[0003] A Chinese patent discloses a waste gas treatment device for aluminum alloy smelting furnaces (authorization announcement number CN219462924U). This patented technology can make good use of high-temperature waste gas, save factory energy expenses, and make full use of spray liquid to avoid resource waste, which is practical.

[0004] Regarding the above-mentioned and existing related technologies, the inventors believe that the following defects often exist: In the waste gas recovery and treatment device of aluminum alloy smelting furnace, the filter plate, as a key component, undertakes the important task of filtering and purifying waste gas. However, in practical applications, the replacement of the filter plate often faces many inconveniences. Since the waste gas treatment device is usually designed to be relatively complex and compact, the filter plate is often fixed inside the device and is difficult to access directly. When the filter plate becomes clogged or damaged due to long-term use and needs to be replaced, the staff often need to spend a lot of time and effort to disassemble the surrounding parts in order to access the filter plate and replace it. This process is not only cumbersome, but also easily damages other parts of the device, increasing maintenance costs. Utility Model Content

[0021] The present invention will now be described in further detail with reference to the accompanying drawings and preferred embodiments. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0022] Reference Figure 1 - Figure 5 As shown, this utility model provides a technical solution: a waste gas recovery and treatment device for an aluminum alloy smelting furnace, including a waste gas treatment device 1. A front plate 2 is fixedly connected to the front end of the waste gas treatment device 1. A fan 3 is installed inside the waste gas treatment device 1. A filter plate 4 is slidably connected inside the front plate 2. Adjustment grooves 5 are provided on both sides of the front plate 2. Adjustment blocks 6 are slidably connected inside the adjustment grooves 5. An insert block 7 is fixedly connected to the front end of the adjustment block 6. A through groove 8 is provided at the front end of the adjustment groove 5. A straight groove 9 is provided at the rear end of the filter plate 4. A slot 10 is provided on one side inside the straight groove 9. When the operator pushes the adjustment block 6 into the adjustment groove 5, the adjustment block 6 causes the insert block 7 to release the restriction between itself and the slot 10. At the same time, the restriction of the filter plate 4 is also released. The operator pulls down the filter plate 4 to disassemble it. When the operator needs to install the filter plate 4, the filter plate 4 is inserted into the front plate 2 and the adjustment block 6 is pulled so that the insert block 7 is inserted into the slot 10 to fix the filter plate 4. Through the above settings, the operator can quickly replace the filter plate 4.

[0023] Reference Figure 1 - Figure 5 As shown in this embodiment: the size of the plug 7 is adapted to the size of the slot 10, and the surface of the plug 7 is slidably connected to the inside of the slot 10. By adapting the size of the plug 7 to the size of the slot 10, the plug 7 is ensured to move smoothly inside the slot 10, preventing it from shifting during movement, thereby improving the overall operating efficiency of the device. In addition, the material of the plug 7 is selected to have good wear resistance and corrosion resistance, so as to extend the service life of the device and reduce maintenance costs.

[0024] Reference Figure 4As shown in this embodiment: a storage spring 11 is fixedly connected to the side of the adjusting block 6 near the inside of the adjusting groove 5, and the side of the storage spring 11 away from the adjusting block 6 is fixedly connected to the inside of the adjusting groove 5. When the operator pushes the adjusting block 6 into the inside of the adjusting groove 5, the adjusting block 6 compresses the storage spring 11 to store force, and at the same time drives the insertion block 7 to release the limit between it and the slot 10. When the operator adjusts the position of the filter plate 4, the insertion block 7 is aligned with the slot 10 and the slider 13 is released. Under the action of the rebound force of the slider 13, the insertion block 7 is quickly inserted into the slot 10 for fixing.

[0025] Reference Figure 4 As shown in this embodiment: both ends of the adjusting groove 5 are provided with sliding grooves 12, and both ends of the adjusting block 6 are fixedly connected with sliders 13. The surface of the sliders 13 is slidably connected to the inside of the sliding grooves 12. When the operator moves the adjusting block 6, the adjusting block 6 drives the sliders 13 to slide inside the sliding grooves 12. Through the above settings, the sliders 13 are ensured to move smoothly inside the sliding grooves 12. At the same time, the surface design of the sliders 13 can effectively reduce friction, thereby reducing the resistance during operation, improving work efficiency, ensuring that good performance can still be maintained under long-term use, and reducing the frequency of replacement and maintenance costs.

[0026] Reference Figure 4 As shown in this embodiment: a top groove 14 is provided at the top of the front plate 2, and a return spring 15 is fixedly connected to the top of the top groove 14. A push block 16 is fixedly connected to the part of the return spring 15. After the operator releases the limit of the filter plate 4, in order to facilitate the operator to disassemble and pick up the filter plate 4, the filter plate 4 is quickly popped out under the action of the rebound force of the top groove 14, thereby improving the operator's disassembly efficiency and making the whole disassembly process more convenient and safe.

[0027] Reference Figure 2 As shown in this embodiment: guide grooves 17 are provided on both sides of the front plate 2, and guide blocks 18 are fixedly connected to both sides of the filter plate 4. The surface of the guide block 18 is slidably connected to the inside of the guide groove 17. When the operator moves the filter plate 4, the filter plate 4 drives the guide block 18 to slide inside the guide groove 17. Through the above settings, the smooth movement of the guide block 18 inside the guide groove 17 is ensured. At the same time, the surface design of the guide block 18 can effectively reduce friction, thereby reducing the resistance during operation, improving work efficiency, ensuring that it can maintain good performance under long-term use, and reducing the frequency of replacement and maintenance costs.

[0028] Reference Figure 2As shown in this embodiment, the filter plate 4 is made of polytetrafluoroethylene (PTFE). By using PTFE as the material for the filter plate 4, the device exhibits excellent corrosion resistance, making it particularly suitable for handling environments containing strong acids, strong alkalis, or other corrosive chemicals. Furthermore, the low coefficient of friction of PTFE further enhances the sliding performance of the device, ensuring stability and reliability during long-term operation.

[0029] Working principle:

[0030] The specific operating steps of the waste gas recovery and treatment device for the aluminum alloy smelting furnace are as follows:

[0031] Step 1: Release the limiting position of filter plate 4 and disassemble it.

[0032] In this step, the operator first needs to push the adjusting block 6 into the adjusting slot 5. This action is crucial because it triggers a chain reaction: as the adjusting block 6 moves, it will move the connected insert 7 together, thereby releasing the limiting relationship between the insert 7 and the slot 10. At the same time, since the limiting relationship between the insert 7 and the slot 10 is released, the limiting relationship of the originally fixed filter plate 4 is also released. At this time, the operator can easily pull down the filter plate 4 to remove it from the equipment. The key to this step is to accurately push the adjusting block 6 to ensure that the insert 7 can smoothly disengage from the slot 10, thereby releasing the fixation of the filter plate 4.

[0033] Step 2: Prepare the new filter plate 4 for installation.

[0034] After removing the old filter plate 4, the staff needs to prepare a new filter plate for installation 4. When preparing the new filter plate 4, the staff needs to carefully check its model, size and performance parameters to ensure that it is fully compatible with the equipment requirements. At the same time, the staff also needs to check whether the new filter plate 4 is damaged or defective to ensure that it can function properly.

[0035] Step 3: Install and secure the new filter plate 4

[0036] The final step is to insert the new filter plate 4 into the front plate 2 and secure it. In this step, the operator needs to first align the new filter plate 4 with the installation position in the equipment, and then gently insert it. Next, pull the adjusting block 6 to re-insert the insert block 7 into the slot 10, thereby securing the new filter plate 4. During this process, the operator needs to ensure that the insert block 7 can be fully and firmly inserted into the slot 10 to prevent the filter plate 4 from becoming loose or falling off during use. At the same time, it is also necessary to check whether the installation position of the filter plate 4 is accurate and whether its fit with the surrounding components is tight to ensure that it can perform its filtering function normally.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present 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 the present utility model should be included within the protection scope of the present utility model.
