A sewage treatment apparatus

Abstract

This utility model belongs to the field of wastewater treatment technology, and in particular to a wastewater treatment device, including a base plate with two side plates welded to the top of the base plate. A common treatment tank is welded to the top of the two side plates. In this utility model, wastewater enters the treatment tank through an inlet pipe and flows through a filter plate for filtration. As the filtration process continues, the filter holes on the filter plate gradually become clogged with impurities, leading to a decrease in filtration efficiency. At this point, the device's start-up motor drives a sliding rod to rotate through a circular plate. When the sliding rod rotates, it pushes a reciprocating plate up and down. The reciprocating motion of the reciprocating plate, through a connecting rod, is transmitted to a reciprocating rod via a support plate and connecting frame. This reciprocating motion causes the reciprocating rod to insert into the filter holes, pushing out the impurities clogging them. This continuous up-and-down motion of the reciprocating rod effectively cleans the filter holes, preventing clogging and ensuring the filtration efficiency of the filter plate.

Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically to a wastewater treatment device. Background Technology

[0002] In the field of wastewater treatment, filtration devices are key equipment, effectively intercepting and separating impurities and particulate matter in wastewater. This is a crucial step in ensuring the stable operation of subsequent treatment processes and that the effluent meets quality standards. Currently, most wastewater treatment equipment widely used in the market relies on filter screens to achieve its filtration function.

[0003] However, in practical applications, wastewater contains a large number of impurities of different particle sizes, such as silt, fibers, hair, and various suspended solids. These impurities easily accumulate and become entangled in the through-holes of the filter screen as the wastewater flows through it. As the filtration process continues, the impurities accumulate, gradually reducing the effective flow area of ​​the through-holes, thus increasing filtration resistance and significantly reducing filtration efficiency. This not only affects the overall treatment capacity of the wastewater treatment equipment but may also lead to wastewater accumulation inside the equipment, increasing the operating load and even causing equipment failure. Even more inconvenient is that when the filter screen becomes clogged, existing methods typically require removing the entire filter screen from the equipment for cleaning. This process is cumbersome and time-consuming, requiring shutdown and disassembly of related components, increasing downtime and reducing production efficiency. Therefore, we propose a wastewater treatment device to solve these problems. Utility Model Content

[0004] (a) Technical problems to be solved

[0014] (III) Beneficial Effects

[0015] Compared with the prior art, the present invention provides a wastewater treatment device with the following advantages:

[0016] In this invention, wastewater enters the treatment tank through the inlet pipe and flows through a filter plate for filtration. As the filtration process continues, the filter holes on the filter plate gradually become clogged with impurities, leading to a decrease in filtration efficiency. At this point, the equipment's start-up motor drives a sliding rod to rotate through a circular plate. When the sliding rod rotates, it pushes a reciprocating plate up and down. The reciprocating motion of the reciprocating plate, via a connecting rod, is transmitted through a support plate and connecting frame to a reciprocating rod, causing the reciprocating rod to insert into the filter holes and push out the impurities clogging them. This reciprocating motion of the reciprocating rod continuously cleans the filter holes, effectively preventing clogging and ensuring the filtration efficiency of the filter plate.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example

[0026] like Figure 1-6As shown, an embodiment of the present invention discloses a wastewater treatment device, including a base plate 1, two side plates 2 welded to the top of the base plate 1, a treatment box 3 welded to the top of the two side plates 2, a filter plate 4 provided inside the treatment box 3, a connecting rod 5 provided at the bottom of the treatment box 3, a support plate 6 welded to the top of the connecting rod 5 extending into the treatment box 3, a connecting frame 7 welded to the top of the support plate 6, multiple inverted rods 8 welded to the top of the connecting frame 7, a limiting ring 9 welded to the connecting rod 5, a spring 10 fixedly connected between the top of the limiting ring 9 and the bottom of the treatment box 3, a U-shaped plate 11 welded to the bottom end of the connecting rod 5, a rectangular plate 12 welded to the top of the base plate 1, a motor 13 fixedly connected to the front side of the rectangular plate 12, a circular plate 14 fixedly connected to the output shaft of the motor 13, a sliding rod 15 provided to the front side of the circular plate 14, the sliding rod 15 slidably connected to the U-shaped plate 11, an inlet pipe 16 connected and fixed to the left side of the treatment box 3, and an outlet valve 17 provided to the right side of the treatment box 3.

[0027] During operation, wastewater enters the treatment tank 3 through the inlet pipe 16. Inside the treatment tank 3, the wastewater flows through the filter plate 4, which has numerous filter holes. Impurities and particulate matter in the wastewater, being larger than the filter holes, are trapped above the filter plate 4. The relatively clean water, after filtration, continues to flow downwards through the filter holes. Finally, the treated water can be discharged from the treatment tank 3 by opening the outlet valve 17, completing the wastewater filtration process. As the filtration process continues, the filter holes on the filter plate 4 gradually become clogged with impurities, leading to a decrease in filtration efficiency. At this point, the equipment starts the motor 13, and the output shaft of the motor 13 begins to rotate, driving the circular plate 14 fixedly connected to it to rotate. The sliding rod 15, located on the front side of the circular plate 14, then performs a circular motion. Since the sliding rod 15 is slidably connected to the U-shaped plate 11, when the sliding rod 15 performs a circular motion, it pushes the U-shaped plate 11... The reciprocating motion of the connecting rod 5, driven by the up-and-down movement of the U-shaped plate 11, causes the connecting rod 5 to reciprocate synchronously. The top of the connecting rod 5 extends into the processing box 3 and is welded with a support plate 6. A connecting frame 7 is welded to the top of the support plate 6, and multiple inverted rods 8 are welded to the top of the connecting frame 7. The inverted rods 8 are aligned with the filter holes on the filter plate 4. Therefore, the up-and-down reciprocating motion of the connecting rod 5 is transmitted to the inverted rods 8 through the support plate 6 and the connecting frame 7, causing the inverted rods 8 to reciprocate up and down. The top of the inverted rod 8 is tapered, which helps the inverted rod 8 to be inserted smoothly into the filter hole. When the inverted rod 8 moves upward, it will insert into the filter hole and push out the impurities blocking the filter hole. When the inverted rod 8 moves downward, it prepares for the next insertion and cleaning. Through this up-and-down reciprocating motion of the inverted rod 8, the filter hole is continuously cleaned, effectively preventing the filter hole from becoming clogged and ensuring the filtration efficiency of the filter plate 4.

[0028] In some embodiments, the spring 10 is movably sleeved on the connecting rod 5. Two mounting grooves 18 with one side open are opened on both sides of the inner wall of the treatment box 3. Mounting rods 19 are provided on the mounting grooves 18. One side of the mounting rod 19 is fixedly connected to one side of the filter plate 4. The top of the four mounting rods 19 is welded to the same top plate 20. Two fixing blocks 21 are welded to both sides of the top plate 20. The fixing blocks 21 are threadedly connected to the treatment box 3 by bolts 22. When it is necessary to replace or clean the filter plate 4, simply unscrew the bolts 22 to disconnect the fixing blocks 21 from the treatment box 3, and the top plate 20 can be removed from the treatment box 3 together with the filter plate 4 via the mounting rods 19. The operation is simple and convenient.

[0029] In some embodiments, the top of the inverted rod 8 is tapered, and the inverted rod 8 is aligned with the filter holes on the filter plate 4. When the inverted rod 8 moves upward, it will be inserted into the filter hole to push out the impurities blocking the filter hole. When the inverted rod 8 moves downward, it will be ready for the next insertion and cleaning. Through this up-and-down reciprocating movement of the inverted rod 8, the filter hole is continuously cleaned, effectively preventing the filter hole from becoming clogged.

[0030] 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.
