Description

Technical Field

[0001] This utility model relates to a sewage purification treatment tank, specifically a sewage purification treatment tank, and belongs to the technical field of sewage treatment equipment. Background Technology

[0002] In the wastewater purification process, sedimentation tanks are the core component for solid-liquid separation. By setting up baffles to divide the tank into multiple sedimentation zones, the residence time of wastewater in the tank is extended, allowing suspended impurities and colloidal particles to settle fully. This improves the efficiency of subsequent filtration and disinfection processes, ensuring that the effluent meets the standards.

[0003] However, traditional sedimentation tanks typically use welded baffles that are rigidly connected to the tank body. Once installed, the size of the zones is permanently fixed. When the wastewater quality is good, a single zone of sedimentation is sufficient. However, traditional fixed baffles cannot be removed, and multiple baffles create flow resistance, increasing the energy consumption of wastewater flowing within the tank. Conversely, when treating high-turbidity wastewater, more stages of sedimentation are needed to gradually reduce the concentration of impurities. However, the number of pre-set baffles in traditional sedimentation tanks is fixed, and no new zones can be added. This results in insufficient residence time of wastewater in a single zone, inadequate sedimentation of impurities, and ultimately poor treatment results. Furthermore, the welded joints between the fixed baffles and the tank body are prone to forming "dead corners" where sludge, fibrous impurities, and other debris accumulate and are difficult to clean over time. Utility Model Content

[0004] The purpose of this invention is to provide a wastewater purification treatment tank to solve the above problems. The position and number of baffles can be flexibly adjusted to cope with diverse wastewater treatment scenarios and improve the applicability and economy of the equipment.

[0005] This utility model achieves the above-mentioned objective through the following technical solution: a sewage purification treatment tank, including a sedimentation tank, wherein the sedimentation tank is provided with multiple partitions inside, and multiple through holes are provided on both sides of the top of the sedimentation tank. A bolt is provided through both sides of the top of the partition, and two bolts are respectively passed through two of the through holes. Nuts are threaded onto the bolts. An opening is provided near the top of the partition, and two grooves are provided on the partition. The bolts are engaged with the adjacent grooves, and the outer side of the partition abuts against the inner side of the sedimentation tank.

[0006] Preferably, the sedimentation tank has an overall trapezoidal cross-section, the baffle has an overall trapezoidal cross-section, and the width of the top section of the baffle is greater than the width of the bottom section.

[0007] Preferably, the multiple through holes located on the same side of the sedimentation tank are linearly and equidistantly distributed, and the two rows of through holes located on both sides of the sedimentation tank are symmetrically distributed about the middle of the sedimentation tank.

[0008] Preferably, a sealing gasket is engaged at the bottom end of the partition, and the sealing gasket is in contact with the sedimentation tank.

[0009] Preferably, two lifting rings are fixedly connected to the top of the partition, and the cross-section of the lifting rings is U-shaped. The two lifting rings are symmetrically distributed about the middle of the partition.

[0010] Preferably, one end of the sedimentation tank is fixedly connected to an inlet pipe, and an inlet pipe flange is fixedly connected to the inlet pipe.

[0011] Preferably, a drain pipe is fixedly connected to the other end of the sedimentation tank, and a drain pipe flange is fixedly connected to the drain pipe.

[0012] Preferably, multiple reinforcing ribs are fixedly connected to both sides of the sedimentation tank. The multiple reinforcing ribs on the same side of the sedimentation tank are linearly and equidistantly distributed, and the two rows of reinforcing ribs on both sides of the sedimentation tank are symmetrically distributed about the middle of the sedimentation tank.

[0013] Preferably, the bottom of the sedimentation tank is fixedly connected with a plurality of support rods, and the support rods have two mounting holes.

[0014] The beneficial effects of this utility model are as follows: When the position of the partition needs to be changed, the nut can be unscrewed from the bolt using a wrench. Because the bolt is engaged with the groove, the bolt will not rotate with the nut during the unscrewing process, thus avoiding the need to fix the bolt during the unscrewing process, thereby improving the convenience of operation. After the two nuts are unscrewed from the two bolts, the two bolts can be removed from the partition, and then the partition can be moved. After the position of the partition is adjusted, the bolt can be passed through the partition and another through hole again and locked with the bolt. When both bolts are locked by the nuts, the partition will be pressed against the sedimentation tank, thus realizing the adjustment of the partition position. Similarly, the partition can be removed from the inside of the sedimentation tank, and new partitions can be added to the inside of the sedimentation tank. Thus, the number and position of the partitions can be adjusted according to the actual situation to cope with diverse sewage treatment scenarios and improve the applicability and economy of the equipment. By setting the partition into a trapezoidal structure that is wider at the top and narrower at the bottom, the two sides of the partition can also be pressed against the inside of the sedimentation tank, thereby improving the sealing between the partition and the sedimentation tank.

[0019] As a technical optimization of this utility model, the overall cross-section of the sedimentation tank 1 is trapezoidal, and the overall cross-section of the partition 2 is trapezoidal, thus improving the sealing between the partition 2 and the sedimentation tank 1. The width of the top section of the partition 2 is greater than the width of the bottom section.

At the same time, by passing the bolt 5 through the partition plate 2 and different through holes 7, the position of the partition plate 2 can be adjusted.

[0021] As a technical optimization of this utility model, a sealing gasket 16 is engaged at the bottom end of the partition 2, and the sealing gasket 16 abuts against the sedimentation tank 1, thereby improving the sealing performance between the bottom end of the partition 2 and the sedimentation tank 1.

[0023] As a technical optimization of this utility model, one end of the sedimentation tank 1 is fixedly connected to an inlet pipe 9, so that sewage can enter the interior of the sedimentation tank 1 from the inlet pipe 9. An inlet pipe flange 10 is fixedly connected to the inlet pipe 9, so that the inlet pipe 9 can be easily connected to the sewage conveying pipeline.

[0024] As a technical optimization of this utility model, a drain pipe 11 is fixedly connected to the other end of the sedimentation tank 1, so that the purified sewage can be discharged from the sedimentation tank 1 through the drain pipe 11. A drain pipe flange 12 is fixedly connected to the drain pipe 11, so that the drain pipe 11 can be conveniently connected to the pipeline for transporting purified water.

[0025] As a technical optimization of this utility model, multiple reinforcing ribs 15 are fixedly connected to both sides of the sedimentation tank 1. The multiple reinforcing ribs 15 located on the same side of the sedimentation tank 1 are linearly and equidistantly distributed.

Wastewater enters the sedimentation tank 1 through the inlet pipe 9 and flows within it. Multiple baffles 2 divide the sedimentation tank 1 into multiple spaces, enabling multi-stage sedimentation and improving the wastewater purification effect. The purified wastewater is ultimately discharged through the drain pipe 11. When the position of the baffles 2 needs to be changed, the nuts 6 can be unscrewed from the bolts 5 using a wrench. Because the bolts 5 are engaged with the grooves 4, they will not rotate with the nuts 6 during the unscrewing process, thus avoiding the need to fix the bolts 5 during unscrewing and improving operational convenience. Once the two nuts 6 are unscrewed from the two bolts 5, the sedimentation tank can be... Remove the two bolts 5 from the partition 2, and then the partition 2 can be moved. After the position of the partition 2 is adjusted, the bolts 5 can be passed through the partition 2 and another through hole 7 again, and locked with the nut 6. When both bolts 5 are locked with the nut 6, the partition 2 will be pressed against the sedimentation tank 1, thus realizing the adjustment of the position of the partition 2. Similarly, the partition 2 can be removed from the inside of the sedimentation tank 1, and a new partition 2 can be added to the inside of the sedimentation tank 1. Thus, the number and position of the partitions 2 can be adjusted according to the actual situation to cope with diverse sewage treatment scenarios and improve the applicability and economy of the equipment. By setting the partition 2 into a trapezoidal structure that is wider at the top and narrower at the bottom, the two sides of the partition 2 can also be pressed against the inside of the sedimentation tank 1, thereby improving the sealing between the partition 2 and the sedimentation tank 1. At the same time, removing the partition 2 from the inside of the sedimentation tank 1 also makes it convenient to clean the sedimentation tank 1 and the partition 2.
