Description

Technical Field

[0001] This utility model relates to the field of packaging technology, specifically to a dosing device for wastewater purification treatment from waste incineration. Background Technology

[0002] In the wastewater purification process of waste incineration, chemical dosing is one of the core links. By adding agents such as sodium hypochlorite and hydrogen peroxide to the wastewater, residual trace pollutants are removed, ensuring that the effluent meets discharge standards or is reused. The uniformity of mixing between the agent and the wastewater and the stability of the dosing directly affect the wastewater treatment efficiency, agent utilization rate and final effluent quality. Therefore, the performance of the dosing equipment is crucial to the entire wastewater purification system. Most existing waste incineration wastewater dosing equipment has a direct injection outlet, which limits the diffusion range of the agent after discharge and results in uneven mixing with the wastewater. This leads to problems such as excessively high or low agent concentrations in some areas, which not only reduces the treatment effect but also wastes the agent. Utility Model Content

[0003] (a) Technical problems to be solved To address the shortcomings of existing technologies, this utility model provides a dosing device for the purification and treatment of wastewater from waste incineration, which solves the problem of limited diffusion range after the reagent is discharged.

[0004] (II) Technical Solution To achieve the above objectives, this utility model provides the following technical solution: a dosing device for purifying wastewater from waste incineration, comprising: a main pipe, a branch pipe assembly connected through the outer wall below the main pipe, and a diffusion assembly connected through the inner wall of the branch pipe assembly; the diffusion assembly includes an outlet, a connecting frame fixedly connected to the inner wall of the outlet, a sleeve fixedly connected to the inner wall of the connecting frame, a tension spring fixedly connected to the inner wall of the sleeve, a sliding rod fixedly connected to the outer wall of the tension spring, a sealing plate fixedly connected to the outer wall of the sliding rod away from the sleeve, a blocking ring abutting the outer wall of the sealing plate near the sliding rod, and a sealing plate abutting the outer wall away from the blocking ring. A connecting rod is fixedly connected, and a rotating shaft is rotatably connected to the outer wall of the connecting rod away from the sealing plate. A diverter plate is fixedly connected to the inner wall of the rotating shaft away from the connecting rod. Through the coordinated operation of the main pipe, the branch pipe assembly, and the diffusion assembly, an integrated structure for graded conveying and diffusion discharge is constructed. The overall structure is compact and stably connected, enabling centralized supply and uniform multi-point dosing of the reagent. The linkage of the various components inside the diffusion assembly provides a stable channel for reagent discharge and achieves initial sealing through the cooperation of the sealing plate and the tension spring, laying the foundation for the backflow prevention function. At the same time, the diverter plate provides structural support for reagent diffusion, improving the stability and practicality of the equipment operation.

[0005] Preferably, the inner wall of the outlet is fixedly connected to the outer wall of the blocking ring, a sealing ring is provided at the contact point between the blocking ring and the sealing plate, the inner wall of the sleeve is slidably connected to the outer wall of the slide rod, and the fixed connection between the blocking ring and the outlet provides stable limiting support for the sealing plate, ensuring the sealing position; the sealing ring improves the sealing performance between the sealing plate and the blocking ring, preventing sewage from flowing back into the dosing pipeline when the machine is stopped, avoiding pipeline blockage and corrosion, and extending the service life of the equipment; the smooth sliding cooperation between the sleeve and the slide rod ensures that the opening and closing action of the sealing plate is stable and reliable, avoiding poor agent discharge due to jamming, and improving the smoothness and stability of equipment operation.

[0006] Preferably, an arc-shaped guide plate is fixedly connected to the outer wall of the diversion plate near the rotating shaft. During dosing, the agent pushes the arc-shaped guide plate to rotate the diversion plate, spreading the agent's range and facilitating mixing with the incineration wastewater. The diversion plate is driven to rotate by the agent's own discharge pressure, eliminating the need for an additional power unit, thus reducing energy consumption and manufacturing costs, as well as minimizing potential failure points and maintenance workload. The arc-shaped guide plate efficiently converts the agent's kinetic energy into rotational force, ensuring stable rotation of the guide plate and a wide and uniform agent diffusion range. This avoids problems of excessively high or low local agent concentrations, improves the mixing efficiency and quality of the agent and wastewater, thereby enhancing the wastewater purification effect and saving on agent usage.

[0007] Preferably, the branch pipe assembly includes a branch pipe, the inner wall of which is connected to the inner wall of the outlet, and the outer wall of which is fixedly connected with an installation hoop. The branch pipe can be bent arbitrarily for easy arrangement and installation. The inner wall above the branch pipe is connected to the inner wall below the main pipe. The arbitrarily bendable characteristic of the branch pipe improves the installation flexibility of the equipment, enabling it to adapt to waste incineration wastewater ponds with various complex structures without requiring adjustments to the wastewater pond structure based on the equipment, thus reducing installation difficulty and construction costs. The installation hoop ensures the stability of the branch pipe after installation, preventing displacement of the dosing point during operation and ensuring the uniformity of reagent dosing. The through connection between the branch pipe and the main pipe and diffusion assembly ensures the unobstructed flow of reagents, reduces the risk of reagent residue and blockage, and improves the adaptability and operational reliability of the equipment.

[0008] (III) Beneficial Effects This utility model provides a dosing device for purifying wastewater from waste incineration. It has the following beneficial effects: (i) The dosing equipment for waste incineration wastewater purification treatment realizes the distribution of the agent from centralized delivery to multi-point diversion through the branch pipe component and the diffusion component. With the flexible installation of flexible branch pipes and the radial diffusion of the rotating diversion plate, the agent can quickly and fully contact the waste incineration wastewater, improve the dosing uniformity and mixing efficiency, and enhance the purification treatment effect.

[0009] (ii) The dosing equipment for waste incineration wastewater purification treatment uses an automatic opening and closing sealing structure composed of tension springs and sealing plates to prevent wastewater backflow, avoid pipeline blockage and corrosion, ensure smooth equipment start-up and shutdown, extend the overall service life, and reduce equipment maintenance costs.

[0012] 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.

[0013] Please see Figures 1-4 This utility model provides a technical solution for a dosing device for waste incineration wastewater purification treatment: it includes a main pipe 1, a branch pipe assembly 2 connected through the outer wall below the main pipe 1, and a diffusion assembly 3 connected through the inner wall of the branch pipe assembly 2; the diffusion assembly 3 includes an outlet 31, a connecting frame 32 fixedly connected to the inner wall of the outlet 31, a sleeve 33 fixedly connected to the inner wall of the connecting frame 32, a tension spring 35 fixedly connected to the inner wall of the sleeve 33, a sliding rod 36 fixedly connected to the outer wall of the tension spring 35, a sealing plate 37 fixedly connected to the outer wall of the sliding rod 36 away from the sleeve 33, a blocking ring 34 attached to the outer wall of the sealing plate 37 near the sliding rod 36, a connecting rod 38 fixedly connected to the outer wall of the sealing plate 37 away from the blocking ring 34, a rotating shaft 39 rotatably connected to the connecting rod 38 away from the outer wall of the sealing plate 37, and a diverter plate 310 fixedly connected to the inner wall of the rotating shaft 39 away from the connecting rod 38.

[0014] The inner wall of outlet 31 is fixedly connected to the outer wall of blocking ring 34. There is a sealing ring at the contact point between blocking ring 34 and sealing plate 37. The inner wall of sleeve 33 is slidably connected to the outer wall of slide rod 36.

[0015] An arc-shaped guide plate is fixedly connected to the outer wall of the diversion plate 310 near the rotating shaft 39. When adding chemicals, the chemicals push the arc-shaped guide plate to rotate the diversion plate 310, spreading the range of the chemicals and facilitating the mixing of the chemicals with the incineration wastewater.

[0016] The branch pipe assembly 2 includes a branch pipe 21, the inner wall of which is connected to the inner wall of the outlet 31, and the outer wall of the branch pipe 21 is fixedly connected with a mounting clamp 22. The branch pipe 21 can be bent arbitrarily for easy arrangement and installation. The inner wall above the branch pipe 21 is connected to the inner wall below the main pipe 1.

[0017] In use, first connect the main pipe 1 to the activated carbon adsorption tower, and place the branch pipe assembly 2 inside the activated carbon adsorption tower. After the equipment is started, external purification agents such as sodium hypochlorite and hydrogen peroxide first enter the main pipe 1. The main pipe 1 serves as a centralized delivery channel, evenly distributing the agents to several branch pipe assemblies 2 connected below. The branch pipes 21 in the branch pipe assembly 2, with their flexible characteristics, are fixed at the preset dosing positions by mounting clamps 22 according to the layout of the sewage tank. The agents are delivered to the diffusion assembly 3 corresponding to each dosing point through the branch pipes 21, completing the graded delivery process from centralized to diverted, ensuring the uniformity of multi-point dosing.

[0018] When the agent flows to the outlet 31 of the diffusion component 3, it generates continuous pressure on the sealing plate 37. When the agent pressure reaches the preset threshold, it will overcome the elastic contraction force of the tension spring 35 and push the sealing plate 37 to move away from the blocking ring 34. At this time, the slide rod 36, which is fixedly connected to the sealing plate 37, slides smoothly along the inner wall of the sleeve 33 to avoid jamming. The outlet 31 opens accordingly, providing a smooth channel for the agent to be discharged. Conversely, when the agent delivery stops, the tension spring 35 returns to its natural contraction state, pulling the slide rod 36 and the sealing plate 37 back to their original positions until the sealing plate 37 and the blocking ring 34 are tightly fitted together, completing the closure of the outlet 31. The connecting frame 32 can provide fixed support for the sleeve 33.

[0019] After outlet 31 is opened, the agent is discharged outward at a certain flow rate, directly impacting the arc-shaped guide plate on the diversion plate 310. The curved surface structure of the arc-shaped guide plate converts the axial kinetic energy of the agent into circumferential driving force, causing the diversion plate 310 to rotate continuously around the shaft 39. During the rotation, the diversion plate 310 cuts and disperses the concentrated discharge agent, causing the agent to spread radially in all directions, covering a larger area of ​​sewage. This breaks the limitations of traditional direct-injection discharge, allowing the agent to come into rapid and full contact with the waste incineration sewage, improving the mixing uniformity. The sealing plate 37 is rotatably connected to the diversion plate 310 through the connecting rod 38.

[0020] After the equipment stops, the sealing plate 37 is tightly fitted with the blocking ring 34 under the action of the tension spring 35. The sealing ring between the two fills the tiny gap, forming a reliable sealing structure. This structure can prevent sewage in the sewage tank from flowing back into the branch pipe 21 and the main pipe 1, avoid the pipes from being blocked by impurities in the sewage, prevent sewage from corroding the pipes, ensure smooth operation when the equipment is started again, and extend the overall service life of the equipment.
