Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to a mixing tank for preparing sewage treatment agents. Background Art

[0002] In the production process of sewage treatment agents, the stirring and mixing link is particularly crucial. However, during this process, especially when water reacts with lime, a large amount of gas is generated, resulting in a significant increase in the air pressure inside the stirring kettle. Traditional coping strategies usually involve opening the exhaust port, but this method is often accompanied by the leakage of dust, posing a certain threat to the environment and operators.

[0003] In the prior art: To solve the above problems of air pressure rise and dust leakage, some technical means have been adopted in the industry. Among them, a common method is to install a cloth bag filtering device at the exhaust port of the stirring kettle. This device is designed to allow gas to pass through while capturing and preventing the leakage of dust. Although this method has achieved the expected effect to a certain extent, there are still some obvious shortcomings.

[0004] Currently, there are still several problems with using a cloth bag filtering device as a solution. The primary problem is that the exhaust efficiency of the cloth bag is not high. Especially when the gas generation volume is large, the filtering effect of the cloth bag will be severely challenged. Secondly, the cloth bag is prone to blockage during use, which not only affects the normal gas discharge but also increases the difficulty of cleaning and maintenance. Finally, the fixing method of the cloth bag is usually not firm enough. Prolonged use or frequent gas impact may cause it to fall off or break, thus losing its filtering function and bringing a leakage risk. Summary of the Utility Model

This design not only ensures that the cloth bag 5 can be closely attached to the mixing barrel 2, improving the overall sealing performance, but also greatly simplifies the installation and disassembly steps. For the convenience of dust cleaning without damaging the overall structural stability of the cloth bag 5, a switch valve is specially arranged on the cleaning pipe 7. The valve selects a rotary butterfly valve 8 with good sealing performance and simple operation, so as to ensure the cleaning efficiency while ensuring the convenience of operation and the sealing performance of the cloth bag. The framework 6 arranged inside the cloth bag 5 is used to maintain the shape of 5 and prevent collapse.

The output shaft of the servo motor 10 extends into the cleaning pipe 7 and is fixedly connected with a rotary butterfly valve 8. The outer side of the rotary butterfly valve 8 fits against the inner wall of the cleaning pipe 7. When it is necessary to clean the dust in the cloth bag 5, the servo motor 10 can be started when the stirring barrel 2 stops operating, driving the rotary butterfly valve 8 in the fixing plate 9 to rotate, so as to facilitate the staff to use tools to clean the dust in the cloth bag 5.

[0033] Reference Figure 4 As shown in Figure 4 , the stabilizing mechanism includes U-shaped clamping plates 11 fixedly connected to the top of the stirring barrel 2 and located on both sides of the exhaust port 4. Installation grooves 13 are opened at both ends inside the U-shaped clamping plates 11. A screw rod 14 is rotatably connected to the inside of one of the installation grooves 13, and a fixing rod 12 is fixedly connected to the inside of the other installation groove 13. Clamping members 18 are threadedly connected to the outer side of the screw rod 14. The clamping members 18 are slidably connected to the fixing rod 12. By rotating the screw rod 14, the clamping members 18 can be driven to move, so that the two clamping members 18 can move towards or away from each other, and then the cloth bag 5 can be fixed on the outer wall of the exhaust port 4, ensuring the tight fit of the cloth bag 5 on the stirring barrel 2, improving the sealing performance, and avoiding the cloth bag 5 falling off or being damaged due to long-term use or frequent gas impact, thus avoiding the leakage risk.

[0034] Reference Figure 2 As shown in Figure 2 , a clamp 15 is arranged outside the exhaust port 4. A locking bolt 16 is arranged inside the clamp 15. The two ends of the clamp 15 are connected by the locking bolt 16. The exhaust port 4 and the cloth bag 5 are connected by the clamp 15. By using the clamp 15 and the locking bolt 16 in cooperation, the sealing performance between the cloth bag 5 and the exhaust port 4 can be further improved, so as to reduce dust leakage.

The inner layer is a fine filtration layer, and the outer layer is a coarse filtration layer. The cloth bag 5 is made of polyester fiber or polytetrafluoroethylene. By adopting the cloth bag 5 with a multi-layer structure design, the inner layer can capture fine dust, and the outer layer intercepts large particles, significantly improving the filtration efficiency and dust holding capacity of the cloth bag 5, effectively preventing the blockage problem of the cloth bag 5, and thus improving the efficiency of the exhaust device of the cloth bag 5.

[0038] Working principle: First, through the setting of the feed hopper 3, water and lime are sent into the mixing barrel 2, and the mixing paddle in the mixing barrel 2 is started. At the same time, in order to improve the filtration efficiency of the cloth bag 5, the cloth bag 5 is designed with a multi-layer structure. Among them, the inner layer is a fine filtration layer, which can effectively capture fine dust; while the outer layer is a coarse filtration layer, whose main function is to intercept large particles. Through this design, not only the filtration efficiency of the cloth bag 5 is improved, but also its dust holding capacity is increased. In order to facilitate the installation and disassembly of the cloth bag 5, the elastic connecting piece is specially selected as the spring hook 20 design. This design not only ensures that the cloth bag 5 can be closely attached to the mixing barrel 2, improving the overall sealing performance, but also greatly simplifies the installation and disassembly steps. In order to facilitate dust cleaning without damaging the overall structural stability of the cloth bag 5, a switch valve is specially set on the cleaning pipe 7. This valve selects a rotary butterfly valve 8 with good sealing performance and simple operation, thus ensuring the cleaning efficiency while also ensuring the convenience of operation and the sealing performance of the cloth bag 5. The skeleton 6 arranged inside the cloth bag 5 is used to maintain the shape of the cloth bag 5 and prevent it from collapsing;

[0039] Subsequently, the adjusting knob can be rotated. Through the rotation of the screw rod 14, the clamping member 18 can be driven to move, so that the two clamping members 18 can move towards or away from each other, and then the cloth bag 5 can be fixed on the outer wall of the exhaust port 4, ensuring the close fit of the cloth bag 5 on the mixing barrel 2, improving the sealing performance at the same time, and avoiding the cloth bag 5 falling off or being damaged due to long-term use or frequent gas impact, thus being able to avoid the leakage risk. Through the combined use of the clamp 15 and the locking bolt 16, the sealing performance between the cloth bag 5 and the exhaust port 4 can be further improved, so as to reduce dust leakage.
