Description

Technical Field

[0001] This utility model relates to the technical field of wastewater treatment agent preparation device, specifically a wastewater treatment agent preparation device. Background Technology

[0002] In the preparation of wastewater treatment agents, traditional mixing devices often suffer from problems such as uneven material mixing, low reaction efficiency, and insufficient structural stability. For example, the heating components are not tightly fitted to the mixing tank, resulting in excessively high local temperatures or heating dead zones, which affects the stability of the agent components. The mixing structure design is simple, and the raw material feeding and mixing processes are separated, which can easily lead to excessively high local concentrations or sedimentation. Insufficient sealing performance can lead to material leakage or the entry of external impurities, affecting product purity. The connection strength of the support and transmission components is insufficient, which can easily cause vibration or loosening after long-term operation, shortening the service life of the equipment. In addition, the integration of flow guiding and mixing functions in traditional devices is low, and the material flow path in the tank is unreasonable, which can easily cause residues or insufficient mixing, increasing the difficulty of subsequent cleaning and waste of raw materials. Utility Model Content

[0003] The purpose of this invention is to provide a wastewater treatment agent preparation device to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a wastewater treatment agent preparation device, comprising a mixing tank, the mixing tank being a vertical cylindrical structure, with a heating ring block fixedly sleeved on its lower outer wall, and multiple bolt limiting plates fixedly connected circumferentially to the upper end face of the heating ring block, the bolt limiting plates being fixedly attached to the lower outer wall of the mixing tank by bolts, a discharge pipe being vertically and fixedly connected through the center of the bottom of the mixing tank, and eight support legs being evenly and fixedly connected circumferentially around the bottom outer periphery, and fixing members being symmetrically and fixedly connected to the outer sides of the mixing tank, the horizontal section of the fixing member being located above the mixing tank, a tank cover being fixedly and sealed at the top opening of the mixing tank by a flange, a water inlet pipe being vertically and fixedly connected to the upper part of one side of the tank cover, and a feed pipe being vertically and fixedly connected to the upper part of the other side, and a motor being fixedly installed on the upper surface of the horizontal section of the fixing member, the output shaft of the motor extending vertically downward and penetrating the tank cover.

[0005] As a further embodiment of this utility model: the lower end of the output shaft of the motor is rotatably connected to a hollow shaft through a coupling. The hollow shaft vertically penetrates the tank cover and extends into the interior of the mixing tank. Its axis coincides with the central axis of the mixing tank and is rotatably and sealed to the tank cover through a bearing.

[0006] As a further embodiment of this utility model: a rotating sleeve is coaxially fixedly sleeved on the lower outer wall of the hollow shaft, and the rotating sleeve is located inside the mixing tank and rotates synchronously with the hollow shaft.

[0007] As a further embodiment of this utility model: at least two storage cylinders are uniformly fixedly connected to the outer wall of the rotating sleeve along the radial direction. The storage cylinders are horizontally arranged hollow cylindrical structures, and their interiors are connected to the inner cavity of the rotating sleeve.

[0008] As a further embodiment of this utility model: the bottom end of the rotating sleeve is coaxially and sealed with a conical bottom of a storage cylinder, the conical bottom of the storage cylinder being an inverted frustum-shaped structure with its lower end contracting towards the center.

[0009] As a further embodiment of this utility model: an annular receiving groove is provided on the upper end face of the cone bottom of the storage cylinder along the circumference. The receiving groove is connected to the bottom end of the storage cylinder.

The integrated installation structure of the fixing parts and the motor enhances the coaxiality of the transmission system, reduces operating vibration, and extends the service life of the equipment. The connected design of the storage cylinder and the rotating sleeve enables the raw materials to be evenly added during the mixing process. Combined with the inverted truncated cone structure of the storage cylinder's conical bottom, the material is guided to gather towards the center and evenly dispersed through guide ribs, avoiding local concentration. The curved stirring blades are positioned directly above the discharge pipe to enhance the agitation of materials at the bottom, prevent sedimentation and buildup, and improve mixing efficiency. The flange sealing connection between the tank cover and the mixing tank, as well as the bearing sealing design of the hollow shaft, effectively prevent material leakage and external contamination, ensuring product purity. The combination of the support legs and anti-slip pads, along with the crossbar connection structure, further enhances the overall stability of the device, adapting to the needs of long-term continuous operation. The integrated connection design of the guide ribs and curved stirring blades strengthens the structural strength, optimizes the material flow path, reduces residue and cleaning difficulty, and minimizes raw material waste.

[0017] 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.

[0018] Please see Figures 1-4 In this embodiment of the present invention, a wastewater treatment agent preparation device includes a mixing tank 1, which is a vertical cylindrical structure. A heating ring block 8 is fixedly sleeved on the lower outer wall of the mixing tank 1. Multiple bolt limiting plates 9 are fixedly connected to the upper end face of the heating ring block 8 along the circumferential direction. The bolt limiting plates 9 are fixedly attached to the lower outer wall of the mixing tank 1 by bolts. A discharge pipe 7 is vertically fixedly connected through the center of the bottom of the mixing tank 1. Eight support legs 6 are evenly fixedly connected along the circumferential direction of the bottom outer periphery. Fixing members 3 are symmetrically fixedly connected to the two sides of the outside of the mixing tank 1. The horizontal section of the fixing member 3 is located above the mixing tank 1. A tank cover 2 is fixedly connected to the top opening of the mixing tank 1 by a flange seal. A water inlet pipe 4 is vertically fixedly connected through the upper part of one side of the tank cover 2, and a feed pipe 17 is vertically fixedly connected through the upper part of the other side. A motor 5 is fixedly installed on the upper surface of the horizontal section of the fixing member 3. The output shaft of the motor 5 extends vertically downward and passes through the tank cover 2.

[0019] In this invention, preferably, the lower end of the output shaft of the motor 5 is rotatably connected to a hollow shaft 16 via a coupling to reduce connection errors and improve transmission stability. The hollow shaft 16 vertically penetrates the tank cover 2 and extends into the interior of the mixing tank 1. Its axis coincides with the central axis of the mixing tank 1 and is rotatably and sealed to the tank cover 2 via a bearing to prevent liquid leakage. A rotating sleeve 11 is coaxially fixedly fitted on the lower outer wall of the hollow shaft 16. The rotating sleeve 11 is located inside the mixing tank 1 and rotates synchronously with the hollow shaft 16, driving the storage cylinder 12 to rotate so that the material is evenly dispersed under centrifugal force. At least two storage cylinders 12 are radially and evenly fixedly connected to the outer wall of the rotating sleeve 11. The storage cylinder 12 is a horizontal hollow cylindrical structure and is connected to the rotating sleeve 11. 1. The inner cavity is interconnected to achieve uniform feeding of raw materials and improve mixing efficiency. The bottom end of the rotating sleeve 11 is coaxially and sealed to the bottom of the storage cylinder cone 15 with an inverted truncated cone structure. The lower end of the cone 15 tapers towards the center to guide material aggregation and avoid residue. The upper end of the storage cylinder cone 15 is provided with an annular receiving groove 14 that communicates with the bottom end of the storage cylinder 12. The lower side of the inner wall is fixedly connected to the guide rib 13 along the generatrix direction. The lower end of the guide rib 13 extends to the center of the bottom of the cone and is fixedly connected to the upper surface of the horizontally set curved stirring blade 10. The curved stirring blade 10 is located directly above the discharge pipe 7 to enhance bottom stirring and prevent sedimentation. The outer wall of the guide rib 13 is in contact with the inner wall of the cone, and the inner wall is inclined towards the hollow shaft 16 to improve the connection strength and guide the material to enhance the mixing effect.

[0020] The working principle of this utility model is as follows: During use, check the connection status of each component of the mixing tank 1, ensuring that the tank cover 2 and the mixing tank 1 are sealed together via flange, and that the water inlet pipe 4 and the feed pipe 17 are unobstructed. Inject an appropriate amount of water into the mixing tank 1 through the water inlet pipe 4, and add the raw material into the storage cylinder 12 through the feed pipe 17. Close the tank cover 2 and lock the flange. Start the motor 5. The output shaft of the motor 5 drives the hollow shaft 16 to rotate via a coupling. The hollow shaft 16 drives the rotating sleeve 11 to rotate synchronously. The storage cylinder 12 rotates circumferentially within the mixing tank 1 along with the rotating sleeve 11. Under the action of centrifugal force, the raw material enters the conical bottom 15 of the storage cylinder 12 through the receiving groove 14 at the bottom of the storage cylinder 12. The cone bottom 15 has an inverted truncated cone structure. The internal guide ribs 13 guide the raw materials to gather towards the center and flow to the curved stirring blades 10. The curved stirring blades 10 rotate with the cone bottom 15 of the storage cylinder to shear and stir the water and raw materials in the mixing tank 1, avoiding sedimentation and accumulation. At the same time, the heating ring block 8 uniformly heats the lower part of the mixing tank 1. The heat is transferred to the internal materials through the outer wall of the mixing tank 1 to promote the reaction. During the reaction, the fixing part 3 ensures the relative position of the motor 5 and the mixing tank 1 is stable, and the support leg 6 maintains the overall balance of the device. After the reaction is completed, the motor 5 and the heating ring block 8 are turned off, and the valve of the discharge pipe 7 is opened. The treated wastewater treatment agent is discharged through the discharge pipe 7.

[0021] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
