Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, and more particularly to a sewage treatment and purification device. Background Art

[0002] In the existing technology, a sewage treatment and purification device is a system specifically used to treat and purify sewage. Its main purpose is to remove pollutants in the sewage so that it meets the discharge standards or reuse requirements;

[0003] In existing technologies, the effectiveness of sewage treatment is poor, mainly due to some limitations of traditional treatment methods and technologies. These treatment systems are often unable to effectively remove tiny suspended solids, organic matter and nutrients in sewage, resulting in a certain concentration of pollutants in the treated sewage. This not only affects the purification effect of sewage and reduces the reuse rate of water resources, but may also lead to the accumulation of these pollutants in the environment, posing a potential threat to ecosystems and human health. In addition, due to the poor treatment effect, these systems often require larger volumes and higher energy consumption, increasing operating costs and resource consumption.

[0004] On the other hand, the sewage treatment device in the prior art has inconveniences in the use and maintenance of the filter plate. As the core component of the sewage treatment system, the filter plate is usually replaced frequently to maintain the treatment effect and quality. However, due to the limitations of the device design, such as fixed installation position, complex structure, etc., the filter plate replacement process is time-consuming and laborious, which not only increases maintenance costs, but may also affect the treatment efficiency due to the downtime during the replacement process. Therefore, developing a sewage treatment device that is convenient for multi-layer treatment and whose filter plates are easy to disassemble and replace quickly is of great significance to improving the operating efficiency of the overall system and reducing maintenance costs.

Through the linkage of the control sleeve, inclined block sleeve, inclined push block, limit block, slide rod and compression spring, the filter plate replacement process is precisely controlled. This design makes the replacement of the filter plate more convenient and ensures the stability and reliability of the device during operation.

[0022] 4. The function of the limit assembly is to limit and fix the locking mechanism, ensuring the safety and accuracy during the filter plate replacement process. Through the cooperation of the rotating sleeve, support rod and arc rod, the limit assembly can effectively block the limit block to prevent it from accidentally moving during the filter plate replacement process.

The rotating plate 5 drives the multiple sets of spiral plates 6 and the separation net 17 to rotate, and the sewage flows into the outer shell 2. The sewage is spirally stirred by the multiple sets of spiral plates 6, thereby stirring the sewage quickly, so that the sewage flows through the separation net 17, and the relatively fine impurities are blocked in the separation net 17. The sewage after the secondary filtration is then discharged through the bottom pipe 18, and finally passed through the activated carbon block 20 for final purification. When the filter plate 7 is blocked after being used for a long time, it needs to be replaced, and the limit assembly on the locking mechanism is released. The multiple sets of push springs 22 push the multiple sets of inclined block sleeves 24, and at the same time, the multiple sets of compression springs 2 The plurality of limit blocks 26 are pulled to drive the transmission sleeve 16 to slide along the plurality of sliders, so that the transmission sleeve 16 drives the push sleeve 15 to release the abutment of the plurality of inclined block sleeves 24, so that the plurality of clamping pieces 13 are released from the clamping of the clamping rod 10, and the clamping sleeve 11 and the clamping rod 10 are clamped.

The filter plate 7 is disassembled, cleaned or replaced, and the filter plate 7 is placed between the connecting pipe 1 and the inlet pipe 32.
