Description

Technical Field

[0001] This utility model relates to the field of mud-water separation technology, and in particular to a hydraulic clarification device. Background Technology

[0002] Sludge-water separation is a physical or chemical process that separates water containing silt from the silt, and it is widely used in environmental engineering, water treatment, and soil remediation. The main purpose of sludge-water separation is to address the problem of silt in water bodies. This silt, as suspended matter, affects water transparency, water quality, and the health of aquatic ecosystems. Clarification reactors can be used for clarification during the sludge-water separation process.

[0003] Currently, clarification reactors are generally equipped with ejectors on the inlet pipe. When wastewater passes through the ejector, the negative pressure generated inside the ejector draws in the reagent, and the high gradient turbulence inside the ejector promotes rapid and uniform mixing of the reagent with the water being treated, thereby quickly destabilizing suspended particles. The sludge at the bottom of the clarification reactor is discharged through the sludge discharge pipe and is not fully utilized. Utility Model Content

[0028] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0029] Reference Figure 1-7 The hydraulic clarification device includes a reaction vessel body 100, a sludge discharge pipe 120, a feed pipe 200, a reaction cone 110, an annular cylinder 700, a baffle plate 300, and an adjustment assembly.

[0030] The bottom of the reactor body 100 is inverted conical and connected to the sludge discharge pipe 120 at its lowest point, which discharges the sludge deposited at the bottom of the reactor body 100. One end of the feed pipe 200 enters through the conical side wall at the bottom of the reactor body 100 and bends upwards at the middle position. A first ejector 210 is installed at the upward-bending end of the feed pipe 200 inside the reactor body 100.

[0031] The reaction cone 110 is fixed in the middle position inside the reactor body. The reaction cone 110 is divided into a reaction zone at the top, a rapid mixing zone in the middle, and a throat at the bottom. The reaction zone is inverted cone-shaped and its bottom is connected to the top of the rapid mixing zone. The rapid mixing zone is cylindrical and its bottom is connected to the top of the throat. A conical connecting section is provided between the throat and the rapid mixing zone. The throat is cylindrical and its diameter is larger than that of the rapid mixing zone. The outlet of the first jet injector 210 extends into the throat and faces the rapid mixing zone.

[0032] The annular cylinder 700 is sleeved on the outside of the reaction cone 110, and the annular cylinder 700 is distributed at intervals on the inner wall of the reactor body 100 and the outer wall of the reaction cone 110. That is, a certain space of flocculation zone is formed between the inner wall of the annular cylinder 700 and the outer wall of the reaction cone 110, and a certain space of clarification zone is formed between the outer wall of the annular cylinder 700 and the inner wall of the reactor body 100.

[0033] An annular groove 600 is provided on the inner side of the top of the reactor body 100, and a water outlet groove 610 is provided on the outer side of the top of the reactor body 100. A water outlet pipe 620 is connected to the bottom of the water outlet groove 610.

[0034] In this design, the top height of the annular cylinder 700 is greater than the height of the top opening of the annular trough 600, while the top height of the reaction cone 110 is less than the top height of the annular cylinder 700. This ensures that the reaction liquid flowing out of the top opening of the reaction cone 110 only enters the flocculation zone and cannot cross the top of the annular cylinder 700 to enter the clarification zone. The solution in the flocculation zone then flows from the bottom into the clarification zone.

[0035] The bottom wall height of the annular trough 600 is greater than the bottom wall height of the outlet trough 610, and the top opening height of the outlet trough 610 is greater than the bottom wall height of the annular trough 600, while the top opening height of the outlet trough 610 is less than the top opening height of the annular trough 600. This allows the supernatant in the clarification zone to overflow into the annular trough 600, and the supernatant in the annular trough 600 to overflow into the outlet trough 610, and then be discharged from the outlet pipe 620.

[0036] The feed pipe 200 is connected to several dosing pipes 800. The dosing pipes 800 are used to add reaction agents, such as lime, sodium hydroxide, PAC, polyferric sulfate, and PAM. Each dosing pipe 800 is connected to a second ejector 810, through which the reagent in the dosing pipe 800 is jetted into the feed pipe 200 for mixing. The feed pipe 200 is equipped with a feed pump 220. All second ejectors 810 are electrically connected to the feed pump 220. If all dosing pipes 800 and feed pumps 220 are connected to the same PLC controller, the PLC controller can control the opening and closing of the second ejectors 810 by receiving feed information from the feed pump 220, thus achieving automatic control of the dosing process. For example, dosing can occur when water is added and stop when water is added; the stop time is adjustable and controlled by PLC programming.

[0037] An acid-base meter 820 is installed inside the reaction vessel body 100, with its detection end located within the reaction zone of the reaction cone 110. The acid-base meter 820 measures the pH of the solution within the reaction zone. The meter 820 is electrically connected to one or both second ejectors 810, meaning both are connected to a PLC controller. The dosing tubes corresponding to the one or two second ejectors 810 electrically connected to the acid-base meter 820 are used to add pH-adjusting agents. Therefore, by setting preset pH adjustment values ​​in the PLC controller, the operation of the corresponding second ejector 810 can be adjusted based on the data fed back by the acid-base meter 820, thereby achieving automatic pH adjustment of the solution.

[0038] The partition 300 is installed at the bottom of the reaction cone 110 so that the partition 300 can close the bottom of the reaction cone 110. A first clearance hole is provided in the middle of the partition 300 so that the first jet 210 can pass through the partition 300 and enter the reaction cone 110.

[0039] The adjustment assembly includes a baffle 400 and a drive component. The partition 300 has several siphon holes 310 along its circumference, such as three or four siphon holes 310. The cross-section of each siphon hole 310 is circular. The baffle 400 is rotatably mounted at the bottom of the reaction cone 110, and is positioned at the bottom of the partition 300. The baffle 400 and the partition 300 are stacked and arranged in a layered manner. A second clearance hole is also provided in the middle of the baffle 400 to allow the first ejector 210 to pass through it, and the baffle 400 can also rotate relative to the first ejector 210.

[0040] The baffle 400 has several connecting holes 410 along its circumference. The number, shape, and size of the connecting holes 410 are the same as those of the siphon holes 310, and they are correspondingly distributed. That is, when the driving component rotates the baffle 400 to a certain angle, the connecting holes 410 and the siphon holes 310 are completely connected. When the driving component rotates the baffle 400 to another angle, the connecting holes 410 and the siphon holes 310 are completely staggered. Therefore, the flow rate of the siphon holes 310 can be adjusted by rotating the baffle 400, thus controlling the amount of siphoned sludge.

[0041] The bottom edge of the connecting hole 410, i.e., the edge furthest from the partition 300, is provided with a rounded chamfer 411 to facilitate better sludge suction. In other embodiments, the cross-sections of the siphon hole 310 and the connecting hole 410 can also be fan-shaped. In other embodiments, the cross-sections of the siphon hole 310 and the connecting hole 410 can also be triangular.

[0042] The driving components include a drive motor 500, a first gear 510, and a second gear 520. A bracket 530 is mounted on the outer wall of the throat of the reaction cone 110. The drive motor 500 is mounted on the bracket 530, with its output end facing downwards and connected to the first gear 510. The first gear 510 meshes with the second gear 520, which is mounted on the outer periphery of the baffle 400. By controlling the drive motor 500 to rotate the first gear 510, the second gear 520 and the baffle 400 can be rotated.

[0043] In other embodiments, the regulating component may also be a valve for adjusting the opening directly disposed in each siphon orifice 310.

[0044] After the wastewater is treated with chemicals at the feed pipe 200, it is accelerated by the first jet injector 210 at the throat and enters the reaction cone 110 for mixing. Simultaneously, as needed, the drive motor 500 rotates the baffle 400 to adjust its opening, siphoning in sludge from the bottom of the reactor body 100. This sludge accelerates floc formation and conserves chemicals. After passing through the rapid mixing zone of the reaction cone 110, the chemicals and sludge in the wastewater are thoroughly mixed before entering the reaction zone. Various substances react rapidly, and the mixture then enters the flocculation zone, where the water flow slows down, and the flocs become larger and heavier. These larger and heavier flocs further enter the clarification zone for sludge-water separation. The clear water rises to the annular trough 600 and flows into the effluent trough 610 for discharge to the next stage. The sludge settles under gravity and is discharged through the sludge discharge pipe. Some sludge can be sucked in through the sludge auxiliary siphon hole 310 as an auxiliary coagulant, as needed.

[0045] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
