Description

Technical Field

[0001] This invention belongs to the technical field of desulfurization wastewater treatment devices, specifically relating to a one-step dosing triplet device for desulfurization wastewater treatment. Background Technology

[0002] Common desulfurization wastewater treatment systems using a three-tank configuration require at least four types of chemicals, and each tank needs a dosing device. This results in weak impact resistance and unstable effluent quality. Therefore, integrated solid-state chemical dosing systems are currently being used instead. The third tank is a flocculation tank, with the overflow effluent entering a clarifier. Integrated chemical systems combine coagulation, adsorption, flocculation, and sedimentation functions; for example, an automatic integrated desulfurization wastewater treatment device with automatic dosing disclosed in patent application number 202020985829.2.

[0003] However, the current triple-compartment tank has a rectangular structure, and the conventional stirring mechanism cannot achieve sufficient mixing at the bottom during the stirring process, resulting in "dead corners". Furthermore, the use of integrated agents requires ensuring uniform dispersion of the agents. Currently, the integrated agents are mainly discharged into the tank through a dosing pipe, which is achieved by relying on a stirrer. However, the position of the dosing pipe is fixed, so the dosing position is relatively concentrated. Summary of the Invention

[0004] This invention provides a one-step dosing triplet device for desulfurization wastewater treatment. The device allows the scraper frame to move at the bottom of the tank, avoiding inadequate bottom stirring; at the same time, it can prevent the dosing points from being concentrated.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows:

[0006] A one-step dosing triplet device for desulfurization wastewater treatment includes a triplet tank body and a stirring mechanism. The triplet tank body has an inlet pipe and an outlet pipe at both ends. A partition is installed inside the triplet tank body, dividing it into a homogenization tank, a reaction tank, and a flocculation tank. These tanks are sequentially connected. Each of the homogenization tank, reaction tank, and flocculation tank is equipped with a stirring mechanism. A horizontally reciprocating scraper frame is installed at the bottom of each tank, driving the scraper frame to move horizontally back and forth. A feeding device and a feeding pipe are fixed at the upper end of the reaction tank, with the feeding pipe connected to the feeding device. A material-dispersing rod is installed inside the reaction tank to disperse the material discharged from the feeding pipe.

[0007] Each scraper frame is slidably connected to the bottom of the three-compartment box; a connecting frame is fixedly connected to the middle of each scraper frame, and a drive cam is provided in the connecting frame. The drive cam is connected to the stirring mechanism, and the stirring mechanism drives the drive cam to rotate.

[0008] The feeding device includes a feeding hopper and a screw feeder, with the feeding hopper connected to the feeding pipe via the screw feeder.

[0009] The scraper frame includes a frame and scrapers, with a plurality of scrapers fixed on the frame; the cross-sectional shape of the scraper is an inverted V.

[0010] The material feeding rod includes a feeding rod and a feeding plate; the feeding plate is fixedly connected to one end of the feeding rod, and the other end of the feeding rod is fixedly connected to the upper end of the stirring shaft located in the reaction chamber; the feeding plate can rotate to the lower end of the feeding pipe under the drive of the stirring shaft, and the material is dispersed by the feeding plate.

[0011] The material feeding rods are provided in several parts, and the material feeding rods are evenly distributed along the center of the stirring shaft; the tilt angle of the plate on each material feeding rod is different.

[0012] One end of the lever is a prism, and a connecting sleeve that is inserted into one end of the lever is fixed on the lever plate. The connecting sleeve has a corresponding prism-shaped hole.

[0013] One end of the lever is connected to a fixing screw via a thread; the fixing screw is used to tighten the connecting sleeve.

[0014] One end of the lever is a hexagonal prism.

[0015] Compared with the prior art, the beneficial effects of this invention are:

[0016] The horizontal reciprocating movement of the scraper frame driven by the stirring shaft agitates the liquid at the bottom, preventing it from accumulating and improving the stirring effect. The material discharged from the feeding pipe is dispersed by the feeding rod, preventing material concentration at the discharge point. The cam structure drives the reciprocating movement of the scraper frame, achieving linkage with the stirring shaft. Attached Figure Description

Detailed Implementation

[0025] The technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] like Figures 1 to 7 As shown, a one-step dosing triplet device for desulfurization wastewater treatment includes a triplet tank body 1 and a stirring mechanism 2. The triplet tank body 1 has an inlet pipe 3 and an outlet pipe 4 at both ends. A partition 5 is installed inside the triplet tank body 1, dividing the interior into a homogenization tank 6, a reaction tank 7, and a flocculation tank 8. The inlet pipe 3 connects to the homogenization tank 6, and the outlet pipe 4 connects to the flocculation tank 8. The desulfurization wastewater enters the homogenization tank 6 through the inlet pipe 3, then passes sequentially through the reaction tank 7 and the flocculation tank 8, and finally exits through the outlet pipe 4 to the clarifier.

[0027] A stirring mechanism 2 is provided in the homogenizing tank 6, the reaction tank 7, and the flocculation tank 8 to stir the liquid in each tank.

[0028] Meanwhile, a scraper frame 9 that can move horizontally back and forth is provided at the bottom of the homogenizing box 6, reaction box 7 and flocculation box 8. The scraper frame 9 is linked to the stirring shaft of the stirring mechanism 2, that is, the scraper frame 9 is driven to move horizontally back and forth through the stirring shaft. The back and forth movement of the scraper frame 9 at the bottom can improve the stirring effect at the bottom and avoid inadequate stirring at the bottom.

[0029] A feeding device 10 and a feeding pipe 11 are fixed at the upper end of the reaction chamber 7. The feeding pipe 11 is connected to the feeding device 10. A material-dispensing rod 12 is provided inside the reaction chamber 7. The material (integrated agent) discharged from the feeding pipe 11 is dispersed by the material-dispensing rod 12. The dispersed integrated agent can be scattered into the reaction chamber 7, thereby avoiding the concentration of the drug in the dispensing position and making the integrated agent dissolve more quickly.

[0030] The above-mentioned stirring mechanism 2 can adopt a common structural setting; it mainly includes a stirring motor and a stirring shaft; the housing of the stirring motor is fixed on the upper part of the three-compartment box 1; the stirring shaft is fixedly connected to the output shaft of the stirring motor; and a stirring paddle is provided on the stirring shaft.

[0031] Furthermore, various structures can be used to achieve the linkage between the scraper frame 9 and the stirring shaft, with the following structure being preferred:

The drive cam 14 is an eccentric cam, and its outer surface can contact the inner surface of the connecting frame 13. The drive cam 14 is connected to the stirring mechanism 2, and the stirring mechanism 2 drives the drive cam 14 to rotate; when the drive cam 14 rotates, it cooperates with the connecting frame 13, thereby realizing the reciprocating movement of the scraper frame 9.

[0033] Furthermore, the aforementioned feeding device 10 includes a feeding hopper 15 and a screw feeder 16. The feeding hopper 15 is connected to the feeding pipe 11 via the screw feeder 16. The material in the feeding hopper 15 is conveyed to the feeding pipe 11 via the screw feeder 16, and the material in the feeding pipe 11 falls into the reaction chamber 7. Both the feeding hopper 15 and the screw feeder 16 are fixedly located at the upper part of the reaction chamber 7.

[0034] Furthermore, the scraper frame 9 is preferably configured with the following structure: it includes a frame 17 and scrapers 18, and a plurality of scrapers 18 are fixed on the frame 17; the cross-sectional shape of the scraper 18 is an inverted V-shape, and it can be made of angle iron.

[0035] Furthermore, the aforementioned material feeding rod 12 includes a feeding rod 19 and a feeding plate 20; the feeding plate 20 is fixedly connected to one end of the feeding rod 19, and the other end of the feeding rod 19 is fixedly connected to the upper end of the stirring shaft located in the reaction chamber 7; the feeding plate 20 can rotate to the lower end of the feeding pipe 11 under the drive of the stirring shaft, that is, the material falling from the feeding pipe 11 can be dispersed by the feeding plate 20.

[0036] Furthermore, there are several material feeding rods 12, which are evenly distributed along the center of the stirring shaft; the tilt angle of the feeding plate 20 on each feeding rod 19 is different, so that the material can be dispersed at different angles.

[0037] Furthermore, to facilitate angle adjustment, one end of the lever 19 is a prism, and a connecting sleeve 21 that is inserted into one end of the lever 19 is fixed on the lever plate 20. The connecting sleeve 21 has a corresponding prism-shaped hole. The connecting sleeve 21 can be inserted into the prism by rotating it at the corresponding angle.

[0038] Furthermore, for easy disassembly and fixation, a fixing screw 22 is threadedly connected to one end of the lever 19; after the connecting sleeve 21 is inserted into the prism, the fixing screw 22 is tightened to press the connecting sleeve 21.

[0039] Furthermore, one end of the aforementioned lever 19 is preferably a hexagonal prism.

[0040] The above description only illustrates the preferred embodiments of the present invention. However, the present invention 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 invention, and all such changes should be included within the protection scope of the present invention.
