Description

Technical Field

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

[0002] A wet scrubbing wastewater treatment system is a device used to treat wastewater generated during wet scrubbing processes. Its main function is to remove suspended solids, heavy metal ions, acids, alkalis, and other pollutants from the wastewater through a series of physical and chemical treatment processes, enabling the wastewater to meet discharge standards or be reusable. The sedimentation tank is a crucial component of this system. Wastewater first enters the sedimentation tank, where larger suspended particles settle to the bottom under gravity, achieving initial solid-liquid separation.

[0003] In existing wet scrubbing wastewater treatment systems, sedimentation tanks often employ a single drain outlet structure. The drain outlet is typically located at the bottom of the inner wall of the sedimentation tank. During operation, wastewater is discharged from the drain outlet at the bottom of the tank. The upward flow of water strongly scours the settled sludge layer, causing the settled sludge particles to resuspend in the water. This secondary suspension of sludge disrupts the solid-liquid separation effect of the sedimentation process and reduces the purification efficiency and stability of the wastewater treatment system. Utility Model Content

[0004] This invention proposes a wet dust removal wastewater treatment device. By sequentially driving the upper second gate plate upward, the drainage channels are opened in a stepped manner, avoiding the secondary suspension of sludge caused by the upward flow of water from the traditional single bottom drain outlet. This effectively ensures the solid-liquid separation effect of the sedimentation process and improves the purification efficiency and stability of the wastewater treatment system.

[0005] The present invention proposes a wet dust removal wastewater treatment device, including a sedimentation tank, a hydraulic drive assembly, a stepped gate assembly and a linkage lifting mechanism. The inner wall of the sedimentation tank is fixedly connected with multiple gate frames at equal intervals, and the inner walls of the gate frames are provided with sliding grooves on both sides.

[0006] The hydraulic drive assembly includes a hydraulic rod fixed to the top of the gate frame and a first gate plate slidably disposed in a groove in the inner wall of the gate frame. The output end of the hydraulic rod passes through the gate frame and is fixedly connected to the top of the first gate plate.

[0007] The stepped gate assembly includes multiple stacked second gates, each second gate being slidably connected to a sliding groove on both sides, forming a stepped sealing structure between adjacent second gates, and the bottom of the lowest second gate abutting against the inner wall of the gate frame.

[0008] The linkage lifting mechanism includes a drive shaft rotatably connected to the outer wall of the gate frame, a winding drum fixed to the drive shaft, and a rope wound around the winding drum. One end of the rope is fixedly connected to the lowest second gate plate, and the other end of the rope passes through positioning rings set on each upper second gate plate in sequence. Limiting rings are fixed on the rope at intervals. The diameter of the limiting rings is larger than the inner diameter of the positioning rings to form a limiting fit.

[0009] Furthermore, a stepped sealing structure is formed between adjacent second gates by a sealing strip fixedly connected to the top via a pressure groove at the bottom, and the sealing strip engages with the pressure groove.

[0010] Furthermore, the sealing strip has a through air cavity inside, and semi-circular protrusions are formed at both ends of the sealing strip, with expansion cavities formed on the inner walls of the semi-circular protrusions.

[0011] Furthermore, two support blocks are rotatably connected to the outer wall of the drive shaft, and the ends of the support blocks are fixedly connected to the outer wall of the gate frame.

[0012] Furthermore, a base is fixedly connected to the outer wall of the gate frame, and a stepper motor is fixedly connected to the outer wall of the base. The output end of the stepper motor is fixedly connected to the transmission shaft.

[0013] Furthermore, the surface of the winding drum is provided with a spiral guide groove, and the rope is arranged at equal intervals along the guide groove when winding.

[0014] Furthermore, the inner wall of the chute is provided with two parallel guide ridges, and the first gate plate and the second gate plate are provided with grooves on both sides that slide in cooperation with the guide ridges.

[0015] The beneficial effects of this utility model, achieved through the above technical solution, are as follows:

[0016] 1. In this application, the second gate at the bottom is pulled up by a rope. Since the rope passes through the positioning rings of each upper second gate and is limited by the limit rings, the second gate at the bottom will drive the upper second gates to rise in sequence during the rise of the second gate at the bottom, opening the drainage channel in a step-by-step manner. This avoids the secondary suspension of sludge caused by the upward flow of water from the traditional single bottom drain outlet, effectively ensuring the solid-liquid separation effect of the sedimentation process and improving the purification efficiency and stability of the wastewater treatment system.

[0017] 2. The spiral guide groove on the surface of the winding drum in this application can make the rope be arranged at equal intervals when winding, ensuring that the rope is subjected to uniform force; the guide protrusion on the inner wall of the chute cooperates with the grooves on both sides of the first gate and the second gate to provide stable guidance for the sliding of the gate.

[0018] 3. The stepped sealing structure between adjacent second gates in this application, in conjunction with the air chamber and expansion chamber in the sealing strip, allows the hydraulic rod to drive the first gate to move downwards, thereby squeezing the second gate above it. The sealing strip is squeezed and sealed, forcing the air in the air chamber into the expansion chambers at both ends, so that the two ends of the sealing strip expand and come into close contact with the inner wall of the gate frame, further improving the sealing effect.

[0025] 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.

[0026] like Figures 1-3 As shown, a wet dust removal wastewater treatment device includes a sedimentation tank 1, a hydraulic drive assembly, a stepped gate assembly, and a linkage lifting mechanism. Multiple gate frames 2 are fixedly connected at equal intervals on the inner wall of the sedimentation tank 1, and sliding grooves 3 are provided on both sides of the inner wall of the gate frame 2.

[0027] The hydraulic drive assembly includes a hydraulic rod 4 fixed to the top of the gate frame 2 and a first gate plate 5 slidably disposed in the slide groove 3 on the inner wall of the gate frame 2. The output end of the hydraulic rod 4 passes through the gate frame 2 and is fixedly connected to the top of the first gate plate 5.

[0028] The stepped gate assembly includes multiple stacked second gates 6, each second gate 6 is slidably connected to the slide groove 3 on both sides, and a stepped sealing structure is formed between adjacent second gates 6, with the bottom of the lowest second gate 6 abutting against the inner wall of the gate frame 2.

[0029] The linkage lifting mechanism includes a drive shaft 9 rotatably connected to the outer wall of the gate frame 2, a winding drum 10 fixed to the drive shaft 9, and a rope 13 wound around the winding drum 10. One end of the rope 13 is fixedly connected to the lowest second gate plate 6, and the other end of the rope 13 passes through the positioning rings 7 provided on each upper second gate plate 6 in sequence. Limiting rings 14 are fixed at intervals on the rope 13. The diameter of the limiting rings 14 is larger than the inner diameter of the positioning rings 7 to form a limiting fit.

[0030] In some embodiments, such as Figure 4 As shown, the adjacent second gate 6 forms a stepped sealing structure through the pressure groove 15 at the bottom and the sealing strip 16 fixedly connected to the top. The sealing strip 16 and the pressure groove 15 are engaged and matched. This arrangement can ensure the sealing performance of the sealing strip 16 and improve the reliability of the seal.

[0031] In some embodiments, such as Figure 4 As shown, the sealing strip 16 has a through-hole air cavity 17 inside, and semi-circular protrusions are formed at both ends of the sealing strip 16. An expansion cavity 18 is formed on the inner wall of the semi-circular protrusions. The design of the air cavity 17 and the expansion cavity 18 gives the sealing strip 16 good elasticity and deformation capability. When the second gate 6 is squeezed against each other, the air cavity 17 and the expansion cavity 18 are deformed under pressure, so that the sealing strip 16 can fit tightly against the pressure groove 15, further enhancing the sealing performance and preventing wastewater leakage.

[0032] In some embodiments, such as Figure 3 As shown, a base 11 is fixedly connected to the outer wall of the gate frame 2, and a stepper motor 12 is fixedly connected to the outer wall of the base 11. The output end of the stepper motor 12 is fixedly connected to the transmission shaft 9. Two support blocks 8 are rotatably connected to the outer wall of the transmission shaft 9, and the ends of the support blocks 8 are fixedly connected to the outer wall of the gate frame 2.

[0033] The two support blocks 8 provide stable support points for the drive shaft 9, sharing the radial and axial forces that the drive shaft 9 experiences during rotation, reducing deformation and wear of the drive shaft 9, and improving its service life; at the same time, the stable support makes the drive shaft 9 rotate more smoothly, ensuring the stability of the winding drum 10's rotation.

[0034] In some embodiments, the surface of the winding drum 10 is provided with a spiral guide groove, and the rope 13 is arranged at equal intervals along the guide groove when it is wound.

[0035] The spiral guide groove can guide the rope 13 to wind neatly and orderly on the take-up drum 10, avoiding the phenomenon of mutual compression, overlap or slippage of the rope 13 during the winding process, ensuring that the rope 13 is subjected to uniform force and extending the service life of the rope 13.

[0036] In some embodiments, the inner wall of the slide groove 3 is provided with two parallel guide ridges, and the first gate plate 5 and the second gate plate 6 are provided with grooves on both sides that slide in cooperation with the guide ridges.

[0037] The cooperation between the guide ridge and the groove provides guidance for the sliding of the first gate 5 and the second gate 6, restricts the offset of the gate during the sliding process, and improves the smoothness of the gate sliding.

[0038] Working principle: During the operation of this wet dust removal wastewater treatment device, the sedimentation tank 1 receives the wastewater generated by the wet dust removal. The wastewater settles and settles in the sedimentation tank 1, and the sludge settles to the bottom of the tank.

[0039] When it is necessary to discharge the treated upper clear liquid, the extension and retraction of the hydraulic rod 4 can drive the first gate 5 to slide up and down in the slide groove 3;

[0040] When it is necessary to open the drainage channel, the hydraulic rod 4 retracts, causing the first gate 5 to move upward and expose the drainage outlet; conversely, the hydraulic rod 4 extends, and the first gate 5 moves downward to close the drainage outlet.

[0041] When the stepper motor 12 starts, it drives the transmission shaft 9 to rotate, and the winding drum 10 rotates accordingly. The rope 13 pulls the lowermost second gate 6 upward. Since the rope 13 passes through the positioning ring 7 of each upper second gate 6 and is limited by the limit ring 14, the lowermost second gate 6 will drive the upper second gate 6 to rise in turn during the upward process, thus opening the drainage channel in a step-like manner.

[0042] It should be noted that the terms “comprising,” “including,” or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0043] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
