Description

Technical Field

[0001] This utility model belongs to the technical field of industrial wastewater treatment equipment, specifically relating to a dosing mixer for a flocculation reaction tank in wastewater treatment. Background Technology

[0002] The wastewater treatment flocculation reaction tank dosing mixer is a specialized device used in industrial wastewater treatment processes to efficiently mix flocculants with wastewater in a flocculation reaction tank. Its core function is to rapidly and evenly disperse the agent into the wastewater through mechanical stirring, fluid dynamics, or other physical actions, promoting the contact between the agent and pollutant particles, creating favorable conditions for subsequent flocculation and sedimentation, thereby improving wastewater treatment efficiency.

[0003] However, in industrial wastewater treatment scenarios, reagents are usually added to storage tanks and mixed and stored using a stirring structure. However, in actual operation, traditional mixing devices often face the dual challenges of reagent sedimentation and tank wall adhesion. When the reagent concentration is high or contains solid particles, sedimentation is likely to occur at the bottom, resulting in uneven concentration of active ingredients. Furthermore, the adhesion of viscous reagents to the tank wall not only affects the uniformity of mixing but may also cause long-term residual deterioration and crystallization, leading to mixing dead zones at the edges and bottom of the tank. This prevents the reagent particles from being fully dispersed, ultimately resulting in the degradation of reagent performance and a decrease in dosing accuracy during the storage stage, and even adversely affecting the subsequent flocculation reaction effect.

[0004] To address the aforementioned issues, this application proposes a chemical mixing device for a flocculation reaction tank in wastewater treatment. Utility Model Content

[0011] As a preferred embodiment of this utility model, a connecting plate is fixedly connected to the bottom surface of the trough frame, and the bottom surface of the connecting plate is fixedly connected to the upper surface of the storage tank.

[0013] As a preferred embodiment of this utility model, a connecting seat is fixedly connected to the front of the rotating motor, and the bottom surface of the connecting seat is fixedly connected to the upper surface of the slot frame.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: By setting the outer surface of the stirring rack to be close to the inner wall and bottom wall of the storage tank with a small gap, the sticky agent adhering to the tank wall can be scraped off under the drive of the rotary motor, avoiding long-term drug residue and deterioration, and the agent at the bottom can be disturbed to prevent sedimentation and ensure uniform concentration. At the same time, the rotary motor drives the sliding frame, rotary motor and stirring rack to rise and fall as a whole through the threaded rod, so that the stirring range covers the entire height of the tank, eliminating the mixing dead zone at the corners and bottom, significantly improving the drug dispersion effect. With the controller for precise control of the dual motors, the stirring speed and lifting frequency can be flexibly adjusted according to the characteristics of the agent to adapt to different working conditions, reduce agent waste, ensure the stability and efficiency of the subsequent flocculation reaction, and operate reliably and maintain conveniently.

Example

[0017] Please see Figure 1-5 The present invention provides the following technical solution: a chemical mixing device for a flocculation reaction tank in wastewater treatment, comprising a base plate 1, a storage tank 2 and a controller 8 respectively arranged above the base plate 1, a stirring frame 9 arranged inside the storage tank 2, the outer surface of the stirring frame 9 being close to the inner wall and the inner bottom wall of the storage tank 2 with a small gap, a trough frame 12 and a rotary motor 15 respectively arranged above the storage tank 2, the output end of the rotary motor 15 being fixedly connected to the top of the stirring frame 9, a sliding frame 17 being slidably connected inside the trough frame 12, the left side of the sliding frame 17 being fixedly connected to the right side of the rotary motor 15, a threaded rod 14 being rotatably connected to the inner wall of the trough frame 12, the outer surface of the threaded rod 14 being threadedly connected to the inner wall of the sliding frame 17, and a rotary motor 13 being arranged above the trough frame 12, the output end of the rotary motor 13 being fixedly connected to the top of the threaded rod 14; In this embodiment, the stirring rack 9 can not only scrape off the medicine adhering to the inner wall of the storage tank 2, but also achieve stirring operation throughout the entire tank through lifting and lowering. At the same time, the controller 8 adopts a programmable logic control (PLC) system, which can accurately control the stirring speed of the rotary motor 15 and the lifting and lowering frequency of the rotary motor 13 according to the type, concentration and mixing requirements of the medicine, so as to realize automated operation, which not only ensures the uniformity of the medicine mixing, but also improves the convenience of equipment operation and the adaptability to working conditions.

[0018] Specifically, a fixing plate 7 is fixedly connected to the back of the controller 8. The bottom surface of the fixing plate 7 is fixedly connected to the upper surface of the base plate 1. In this embodiment, the controller 8 is stably installed on the base plate 1 by the fixing plate 7, which not only ensures the installation stability of the controller 8, but also maintains a reasonable distance between it and the storage medicine tank 2, which facilitates the wiring layout and equipment operation.

[0019] Specifically, two sets of connecting columns 6 are fixedly connected to the bottom surface of the base plate 1. Each connecting column 6 has a support ring 5 fixedly connected to its bottom end. In this embodiment, the equipment is supported on the ground by the cooperation of the connecting column 6 and the support ring 5. This not only increases the height of the base plate 1 above the ground and prevents the bottom of the equipment from being corroded by the damp ground, but also increases the contact area with the ground by the support ring 5, thereby enhancing the stability of the equipment.

[0020] Specifically, a fixing frame 3 is fixedly connected to the outer surface of the storage tank 2. The bottom surface of the fixing frame 3 is fixedly connected to the upper surface of the base plate 1. In this embodiment, the storage tank 2 and the base plate 1 are firmly connected by the fixing frame 3, which effectively distributes the weight load of the storage tank 2 and prevents it from shifting or tipping over due to vibration during the stirring operation, thus ensuring the safe operation of the equipment.

[0021] Specifically, two sets of dosing pipes 10 are fixedly connected to the upper surface of the storage tank 2, and a dispensing pipe 4 is fixedly connected to the outer surface of the storage tank 2. A flange 11 is fixedly connected to the outer surface of each dosing pipe 10 and dispensing pipe 4. In this embodiment, the dosing pipe 10 enables the rapid addition of the medicine, and the dispensing pipe 4 completes the delivery of the mixed medicine. The flange 11 facilitates the sealed connection between the dosing pipe 10, the dispensing pipe 4 and the external pipeline, reducing the risk of leakage during the delivery of the medicine.

[0022] Specifically, a connecting plate 16 is fixedly connected to the bottom surface of the trough frame 12. The bottom surface of the connecting plate 16 is fixedly connected to the upper surface of the storage tank 2. In this embodiment, the trough frame 12 and the storage tank 2 are stably connected by the connecting plate 16, which provides reliable support for the trough frame 12 and the rotating motor 13, threaded rod 14 and other components installed on it, and ensures the structural stability of the stirring rack 9 during lifting operations.

[0023] Specifically, two limiting rings 18 are rotatably connected to the outer surface of the threaded rod 14. The two limiting rings 18 are fixedly connected to the inner top wall and inner bottom wall of the slot frame 12 on opposite sides. In this embodiment, the axial position of the threaded rod 14 is constrained by the two limiting rings 18 to prevent it from moving up and down during rotation. At the same time, the lifting range of the sliding frame 17 is limited to avoid the stirring frame 9 from colliding with the storage tank 2 due to excessive lifting.

[0024] Specifically, a connecting seat 19 is fixedly connected to the front of the rotating motor 13, and the bottom surface of the connecting seat 19 is fixedly connected to the upper surface of the slot frame 12. In this embodiment, the rotating motor 13 is firmly installed on the slot frame 12 through the connecting seat 19, which enhances the stability of the motor during operation, reduces the noise and wear of components caused by vibration, and extends the service life of the equipment.

[0025] The working principle and usage process of this utility model are as follows: First, the equipment is fixed to the ground via the connecting column 6 and support ring 5 on the bottom surface of the base plate 1. Then, the external drug delivery pipeline is connected via the flange 11 on the outer surface of the dosing pipe 10. After ensuring a seal, the drug is added to the storage tank 2. Next, the PLC system of the controller 8 is started, and the stirring speed of the rotary motor 15 and the lifting frequency of the rotary motor 13 are set. The rotary motor 15 drives the stirring frame 9 to rotate at high speed. Its outer surface, designed to be close to the tank wall, scrapes off adhering drug in real time and agitates the bottom to prevent sedimentation. Simultaneously, the rotary motor 13 drives the threaded... Rotating rod 14 causes sliding frame 17 to move up and down along trough frame 12 via threaded transmission, driving stirring frame 9 to complete lifting and lowering actions, forming a three-dimensional stirring flow field covering the entire height of the tank, eliminating mixing dead zones. At this time, the uniformly mixed agent is transported to the flocculation reaction tank through the outlet pipe 4 and the pipeline connected by flange 11. During the process, controller 8 adjusts the parameters of dual motors in real time according to the characteristics of the agent. The equipment is securely installed through components such as fixed frame 3 and connecting plate 16. Limit ring 18 restricts the axial displacement of threaded rod 14, ensuring accurate lifting and lowering of stirring frame 9, avoiding collision with the tank, and ensuring long-term stable operation.
