Detailed Implementation

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0028] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0029] Please see Figures 1 to 5 The present invention provides a sterilization and dosing device for a hospital wastewater treatment plant, which includes a base plate 1.

[0030] In the embodiments of this utility model, please refer to Figures 1 to 5 A mixing box 2 is fixedly installed on the top of the base plate 1, and dosing components 3 for dispensing the agent are mounted on both sides of the top of the base plate 1. The dosing components 3 include a support frame 31, which is fixedly installed on the top of the base plate 1. A winding frame 32 is rotatably connected to the side wall of the support frame 31. The inside of the winding frame 32 is hollow. A discharge pipe 321 communicating with the inside of the winding frame 32 is fixedly installed on the winding frame 32. The discharge pipe 321 is wound around the winding frame 32, and a discharge head 322 is fixedly installed at the end of the discharge pipe 321 away from the winding frame 32. A rotatably connected worm gear 311 is mounted on the outer wall of the support frame 31 near the winding frame 32. A meshing worm wheel 312 is provided on the outside of the worm gear 311. The worm wheel 312 is fixedly sleeved on the outer wall of the winding frame 32, and the side wall of the support frame 31... A motor driving the worm gear 311 is installed. A support frame 33 is fixedly installed on the outer wall of the discharge pipe 321 near the discharge head 322. A guide pipe 34 is fixedly installed at the bottom of the support frame 33. The guide pipe 34 is fixedly connected to and communicates with the discharge head 322. A rotatably connected central shaft is mounted inside the guide pipe 34. A drive blade 35 is provided on the central shaft. The drive blade 35 abuts against and slides against the inner wall of the guide pipe 34. Both ends of the central shaft of the drive blade 35 extend to the outside of the guide pipe 34. A mixing blade 351 is fixedly installed at both ends of the central shaft. A connected dosing pipe 341 is fixedly installed below the drive blade 35. A one-way valve is fixedly installed on the dosing pipe 341. A filter screen 331 is fixedly installed on the outer wall of the support frame 33 to protect the mixing blade 351.

[0031] It should be noted that during the dosing process, the motor working in the dosing assembly 3 will drive the worm 311 to rotate. The rotating worm 311 will drive the winding frame 32 to rotate through meshing with the worm wheel 312, and release the discharge pipe 321 wound on the winding frame 32. At this time, the discharge pipe 321 and the discharge head 322 will fall into the sewage, thereby discharging the proportioned medicine solution into different heights inside the sewage.

[0032] During this process, when the prepared medicine flows into the guide pipe 34 through the discharge head 322, the flowing medicine will drive the drive blade 35 and the mixing blade 351 outside it to rotate synchronously by impacting the drive blade 35. The medicine passing through the drive blade 35 will flow out smoothly through the dosing pipe 341. At this time, the mixing blade 351 stirs and mixes the discharged medicine and sewage, which can accelerate the diffusion rate of the medicine in the sewage and thus improve the reaction efficiency of the medicine with the sewage in the later stage.

[0033] It should also be noted that by installing a filter screen 331 on the support frame 33, the filter screen 331 can filter relatively large impurities in the sewage, thereby avoiding the impact of impurities getting tangled on the mixing blades 351 and affecting the rotation of the mixing blades 351; in order to prevent the dosing component 3 from being unable to sink smoothly into the sewage tank due to the influence of buoyancy, a counterweight can be installed at the bottom of the support frame 33.

[0034] Meanwhile, a one-way valve is installed on the dosing pipe 341 to prevent sewage from flowing back into the guide pipe 34 when the dosing pipe 341 is inserted into the sewage tank and no chemicals are added.

[0035] In the embodiments of this utility model, please refer to Figures 1 to 5 The top of the mixing tank 2 is provided with a dosing assembly 4. The dosing assembly 4 includes a top cover 41, which is fixedly installed on the top of the mixing tank 2. Multiple evenly distributed dosing pipes 411 are fixedly installed inside the top cover 41. The top end of the dosing pipe 411 is provided with a connected dosing cylinder 42, and a solenoid valve 412 and a flow meter 413 are fixedly installed on the dosing pipe 411.

[0036] It should be noted that by setting up multiple dosing cylinders 42, when adding chemicals, the solenoid valve 412 on the dosing pipe 411 can be opened to allow the chemicals in the dosing cylinders 42 to flow into the mixing tank 2 automatically. During this process, the dosage of each chemical can be accurately controlled by the flow meter 413, thus making the chemical ratio more accurate in the later stages.

[0037] In the embodiments of this utility model, please refer to Figures 1 to 5 A water inlet pipe 21 is embedded in one side wall of the mixing box 2. The side of the mixing box 2 away from the water inlet pipe 21 has a hollow structure and a side plate 5 is fixedly installed by bolts. A mixing frame 52 is provided on the side of the side plate 5 near the mixing box 2. The outer wall of the mixing frame 52 abuts against and slides against the inner wall of the mixing box 2. A mixing motor 51 that drives the mixing frame 52 is fixedly installed on the outer wall of the side plate 5 away from the mixing frame 52.

[0038] It should be noted that by inserting the mixing rack 52 into the mixing box 2, it is easier for staff to disassemble the mixing rack 52 when it is damaged during subsequent use. The quick disassembly and removal of the mixing rack 52 makes it easier for staff to maintain and replace it later.

[0039] In the embodiments of this utility model, please refer to Figures 1 to 5 A three-way pipe 22, which communicates with the interior of the mixing box 2, is fixedly installed at the center of the bottom. A control valve 221 is fixedly connected to the branch pipe on the side of the three-way pipe 2 away from the mixing box 2. A controller 12 is installed on the top of the base plate 1. Pump bodies 11 are installed on both sides of the top of the base plate 1. The input end of the pump body 11 is connected to the end of the three-way pipe 22. The output end of the pump body 11 is fixedly connected to the side wall of the support frame 31 and communicates with the interior of the winding frame 32.

[0040] It should be noted that by installing pump bodies 11 on two branches of the three-way pipe 22 and connecting them to the two dosing components 3 respectively, when a component in one dosing component 3 is damaged during subsequent use, the dosing component 3 on the other side can be activated. This allows the device to continue dosing operations while the operator is repairing the damaged dosing component 3, thereby reducing the impact of damage to the dosing component 3 on the overall dosing process.

[0041] The working principle of the hospital wastewater treatment plant sterilization and dosing device provided by this utility model is as follows:

[0042] When using this device, it can be fixedly installed in the required position by the base plate 1. Then, various agents required for the preparation ratio can be added into the inside of multiple dosing cylinders 42. Then, the solenoid valves 412 on multiple dosing pipes 411 can be opened by the controller 12, so that the agents in the corresponding dosing cylinders 42 can flow into the mixing tank 2. During this process, the controller 12 can monitor the added dosage in real time by the flow meter 413. When the added agent reaches the set value, the solenoid valve 412 can be closed to complete the addition of the prepared agent. During this process, water can be added into the mixing tank 2 through the water pipe 21.

[0043] After the medicine and water are added, the mixing motor 51 can be started to drive the mixing frame 52 to rotate, so as to fully stir the medicine added inside the mixing box 2;

[0044] Once the reagents are mixed in the correct proportions, the dosing assembly 3 can be controlled to operate. The motor in the dosing assembly 3 will drive the worm gear 311 to rotate. The rotating worm gear 311 will drive the winding frame 32 to rotate through meshing with the worm wheel 312. The rotating winding frame 32 will release the discharge pipe 321 wound above, and at this time the discharge pipe 321 will fall into the sewage.

[0045] During this process, the control valve 221 and pump body 11 corresponding to the working dosing component 3 can be opened. The working pump body 11 can then input the proportioned medicine solution inside the mixing tank 2 into the discharge pipe 321 through the three-way pipe 22 and inject it into the external guide pipe 34 through the discharge head 322 at the end of the discharge pipe 321. At this time, the medicine solution flowing inside the guide pipe 34 will drive the drive blade 35 and the external mixing blade 351 to rotate synchronously by impacting the drive blade 35. The medicine passing through the drive blade 35 will flow out smoothly through the dosing pipe 341. At this time, the mixing blade 351 stirs and mixes the discharged medicine and sewage, thereby accelerating the diffusion speed of the medicine in the sewage, thus improving the reaction efficiency of the medicine with sewage in the later stage.

[0046] The circuits and controls involved in this utility model are all existing technologies, and will not be described in detail here.

[0047] The above are merely embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
