Description

Technical Field

[0001] This utility model relates to the field of medical wastewater treatment technology, and specifically discloses a medical wastewater treatment device. Background Technology

[0002] Medical wastewater mainly comes from hospital clinics, laboratories, wards, laundry rooms, X-ray rooms, and operating rooms. Its sources and composition are very complex. Hospital wastewater contains a large number of pathogenic bacteria, viruses, and chemical agents, and has the characteristics of spatial pollution, acute infection, and latent infection. Therefore, medical wastewater needs to be treated with chemicals to prevent environmental pollution.

[0003] Chinese patent CN215326979U discloses a medical wastewater treatment device. In use, wastewater is added through a filling hopper. Then, a fixed plate is pulled, causing a sliding plate to move. The sliding plate compresses a spring, causing the fixed plate to move out of its fixed slot. Next, a linkage plate is pulled, causing a mating plate to move. The mating plate then moves a moving plate, which in turn moves a pressing plate, moving the linkage plate to one side of a measuring cylinder. The measuring cylinder is then removed. Next, an upper plate is pushed, causing a cover plate to move. The cover plate moves a guide plate, which in turn moves an inlet plate, causing it to move out of its inlet slot. The cover plate is then removed. The required amount of wastewater treatment medication is accurately measured through the measuring cylinder. The drive motor is then started, and the measured medication is added to the container. The medication slowly falls into the wastewater through a fine hole. The output shaft of the drive motor rotates the drive shaft, which in turn rotates the stirring blades, ensuring thorough mixing of the wastewater and medication, thus accelerating wastewater purification.

[0004] The aforementioned device has significant drawbacks in practical use: Firstly, when medical wastewater is directly injected into the tank through the filling hopper, the lack of a filtration mechanism allows solid impurities such as gauze, cotton swabs, tissue residue, and plastic fragments, often mixed in with the wastewater, to easily enter the tank. This can not only clog the drain hole but also make it difficult to clean the internal solid impurities due to the integrated structural design of the tank. Secondly, during drug addition, the device integrates numerous mechanical components such as sliding plates, springs, linkage plates, and L-shaped plates, resulting in a complex structure. Operation requires sequentially performing steps such as "pulling the fixed plate → moving the linkage plate → removing the measuring cylinder → adding drugs → resetting the components," making it cumbersome. Therefore, a medical wastewater treatment device is needed to solve this problem. Utility Model Content

[0027] The present invention will be further described below with reference to the accompanying drawings and specific embodiments to aid in understanding its content. Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.

[0028] Please see Figure 1-5 A medical wastewater treatment device includes a treatment tank 1, a connection port 2 that is fixedly connected through the outer wall of the treatment tank 1, a water filling cylinder 3 that extends above the connection port 2, a filter screen plate 12 that is installed inside the water filling cylinder 3, and a connection mechanism that is provided on the outer side of the treatment tank 1.

[0029] The connecting mechanism includes two vertical plates 9 fixedly connected to the outer wall of the treatment tank 1. Fixed rods 8 are fixedly connected to the opposite side of the two vertical plates 9. Turntables 7 are rotatably connected to the opposite side of the two fixed rods 8. Movable rods 5 are fixedly connected to the opposite side of the two turntables 7. Slide grooves 4 are opened on both the left and right sides of the outer wall of the water filling cylinder 3. Sliding sliders 6 fixedly connected to the movable rods 5 are slidably connected inside the two slide grooves 4.

[0030] A measuring cylinder 13 is installed above the processing tank 1. A transparent plate 14 is fixedly connected through the rear end of the outer wall of the measuring cylinder 13. A scale line 15 is provided on the outer wall of the transparent plate 14. A vertical pipe 16 with a hand valve 17 is connected between the measuring cylinder 13 and the processing tank 1.

[0031] A locking mechanism is provided on the outside of the water filling cylinder 3.

[0032] In this embodiment: When in use, sewage is injected through the flared end at the top of the water filling cylinder 3. After the sewage is filtered by the filter screen plate 12, solid particles are trapped above the filter screen plate 12. The purified liquid enters the treatment tank 1 through the connection port 2, thereby achieving the purpose of pre-treating the solid impurities in the sewage and preventing impurities from entering the interior of the treatment tank 1.

[0033] The agent is then injected through the top opening of the measuring cylinder 13. The volume of the liquid is observed through the transparent plate 14 and the scale line 15. After the required dosage is reached, the hand valve 17 is opened, and the agent flows into the treatment tank 1 through the vertical pipe 16, thus completing the quantitative dosing. This method simplifies the quantitative dosing structure, reduces mechanical complexity, and improves operational convenience. It should be noted that the bottom of the scale line 15 is the initial non-zero scale, which corresponds to the volume of residual agent between the valve body and the initial scale when the hand valve 17 is closed. The flow rate of the agent entering the treatment tank 1 can be adjusted by controlling the opening of the hand valve 17.

[0034] Subsequently, the drive motor 21 drives the main shaft 19 and the stirring blades 20 to rotate at high speed, so that the reagent and the sewage are fully mixed, improving the reaction efficiency. After the treatment is completed, the valve of the drain valve pipe is opened, and the sewage is discharged from the drain valve pipe.

[0035] When it is necessary to clean the impurities trapped at the top of the filter screen 12, the locking mechanism is used to release the water filling cylinder 3. Then, the water filling cylinder 3 is lifted upward along the direction of the slide groove 4. After rising to a certain position, the water filling cylinder 3 and the two movable rods 5 rotate with the two turntables 7, thereby rotating the water filling cylinder 3 to an inclined state. Due to the effect of gravity, the solid impurities inside the water filling cylinder 3 will be discharged from the flared end of the water filling cylinder 3. If necessary, tools can be used to assist in cleaning, so as to achieve quick sludge removal and thus facilitate the cleaning of the trapped fixed impurities.

[0036] As a technical optimization of this utility model, the locking mechanism includes an annular plate 10 disposed on the outside of the water filling cylinder 3. An annular groove is provided on the inner wall of the annular plate 10. An annular slide rail fixedly connected to the water filling cylinder 3 is slidably connected inside the annular groove. An internal thread ring 11 that is threadedly connected to the outer wall of the connection port 2 is fixedly connected to the lower end of the annular plate 10.

[0037] In this embodiment, the annular plate 10 and the water filling cylinder 3 are axially slidably connected through an annular slide rail and an annular groove. When the annular plate 10 is rotated, the internal thread ring 11 at its lower end engages or disengages with the thread on the outer wall of the connection port 2, thereby achieving quick locking or disassembly of the water filling cylinder 3. This structure not only ensures the stability of the water filling cylinder 3 during installation but also simplifies the cleaning process of the filter screen plate 12. Only by rotating the annular plate 10 can the water filling cylinder 3 be lifted as a whole or tilted to discharge slag, making the operation convenient and the sealing reliable.

[0038] As a technical optimization of this utility model, a main shaft 19 is rotatably connected between the left and right sides of the inner wall of the processing tank 1. Multiple evenly distributed stirring blades 20 are installed on the outer wall of the main shaft 19. A drive motor 21 with its output end fixedly connected to the main shaft 19 is installed at the left end of the processing tank 1.

[0039] In this embodiment: after the drive motor 21 is started, it drives the main shaft 19 and the evenly distributed stirring blades 20 to rotate at high speed. The rotation of the stirring blades 20 promotes the full mixing of wastewater and reagents and accelerates the reaction process.

[0040] As a technical optimization of this utility model, annular grooves are provided on the opposite sides of the two turntables 7, and annular slide rails that are fixedly connected to the fixed rods 8 are slidably connected inside the two annular grooves.

[0041] In this embodiment, the turntable 7 is slidably connected to the annular slide rail on the fixed rod 8 through the annular groove on its back side, so that the turntable 7 always maintains axial limitation with the fixed rod 8 during rotation, preventing lateral displacement when the water filling cylinder 3 is tilted.

[0042] As a technical optimization of this utility model, the part of the water filling cylinder 3 located above the two sliding grooves 4 has a flared structure.

[0043] In this embodiment, the top of the water filling cylinder 3 is designed with an flared opening to increase the inlet cross-sectional area when sewage is poured, thereby improving the convenience of operation.

[0044] As a technical optimization of this utility model, the outer wall of the measuring cylinder 13 is threadedly connected with a threaded cap 18.

[0045] In this embodiment, the threaded cap 18 at the top of the measuring cylinder 13 is sealed by screwing to prevent external contamination. During operation, the medicine can be added directly by unscrewing the threaded cap 18, and a sealed space is formed after closing.

[0046] As a technical optimization of this utility model, a drain valve pipe is connected to the right end of the treatment tank 1.

[0047] In this embodiment: by setting up a drain valve pipe, when the valve of the drain valve pipe is opened, the treated water inside the treatment tank 1 can be discharged.

[0048] The working principle and usage process of this utility model are as follows: When in use, sewage is injected through the flared end at the top of the water filling cylinder 3. After the sewage is filtered by the filter screen plate 12, solid particles are trapped above the filter screen plate 12. The purified liquid enters the treatment tank 1 through the connection port 2, thereby achieving the purpose of pre-treating the solid impurities in the sewage and preventing impurities from entering the interior of the treatment tank 1.

[0049] The agent is then injected through the top opening of the measuring cylinder 13. The volume of the liquid is observed through the transparent plate 14 and the scale line 15. After the required dosage is reached, the hand valve 17 is opened, and the agent flows into the treatment tank 1 through the vertical pipe 16, thus completing the quantitative dosing. This method simplifies the quantitative dosing structure, reduces mechanical complexity, and improves operational convenience. It should be noted that the bottom of the scale line 15 is the initial non-zero scale, which corresponds to the volume of residual agent between the valve body and the initial scale when the hand valve 17 is closed. The flow rate of the agent entering the treatment tank 1 can be adjusted by controlling the opening of the hand valve 17.

[0050] Subsequently, the drive motor 21 drives the main shaft 19 and the stirring blades 20 to rotate at high speed, so that the reagent and the sewage are fully mixed, improving the reaction efficiency. After the treatment is completed, the valve of the drain valve pipe is opened, and the sewage is discharged from the drain valve pipe.

[0051] When cleaning the impurities trapped at the top of the filter screen 12, rotate the internal thread ring 11 to separate it from the connection port 2. The annular plate 10 is limited by the cooperation of the annular slide rail and the annular slide groove, which drives the water filling cylinder 3 to move upward, thereby releasing the fixation of the water filling cylinder 3. Then, the water filling cylinder 3 is lifted upward along the direction of the slide groove 4. After rising to a certain position, the water filling cylinder 3 and the two movable rods 5 rotate with the two turntables 7, so that the water filling cylinder 3 can be rotated to an inclined state. Due to the effect of gravity, the solid impurities inside the water filling cylinder 3 will be discharged from the flared end of the water filling cylinder 3. If necessary, tools can be used to assist in cleaning, so as to achieve quick sludge removal and thus facilitate the cleaning of the trapped fixed impurities.
