Detailed Implementation

[0029] The present invention will now be described in further detail with reference to the accompanying drawings.

[0030] Please see Figure 1-5 As shown in the figure, this embodiment provides an automatic safety adjustment device for the confined space environment of a hospital sewage treatment station, including a sewage treatment device 1. The sewage treatment device 1 consists of a storage tank 2, a filter device 15, a solid collection mechanism 18, a second filter mechanism 9, and a sterilization tank 10. The filter device 15 and the solid collection mechanism 18 are installed between the storage tank 2 and the sterilization tank 10. The second filter mechanism 9 is installed at the upper end of the sterilization tank 10. A controller 3 is installed on one side of the storage tank 2. One side of the bottom of the storage tank 2 is connected to the filter device 15. One side of the filter device 15 is connected to the solid collection mechanism 18. The other end of the filter device 15 is connected to the second filter mechanism 9. The bottom of the second filter mechanism 9 is connected to the bottom of the sterilization tank 10. A sterilization mechanism 11 is installed on the upper side of the sterilization tank 10. A siphon pipe 12 is installed on one side of the sterilization tank 10.

[0031] One application of this embodiment is as follows: When the wastewater treatment device 1 is put into use, the wastewater to be treated first flows into the storage tank 2 through the inlet pipe 6. When the electronic level gauge 7 measures that the liquid level inside the storage tank 2 has reached a higher set value, the electronic level gauge 7 is an E+HFMU40 ultrasonic level gauge, which transmits the liquid level signal to the controller 3 in the form of a 4-20mA analog signal. The controller 3 is a Siemens S7-1200 series programmable logic controller (PLC). As the core control component of the entire wastewater treatment device 1, the PLC has powerful logic operation and control capabilities. After receiving the liquid level signal, the controller 3 issues instructions according to the preset program to control the Siemens 1LA7 filter in the filtration device 15. When the three-phase asynchronous motor 23 is started, it drives the first filter mechanism 13 and the guide mechanism 8 in the filter device 15. The first filter mechanism 13 uses the negative pressure generated by the rotating screw rod 25 to extract and transport water from the storage tank 2. The wastewater passes through the filter cover 19 under the transport action of the screw rod 25. The filter cover 19 can effectively separate the solids and liquids in the wastewater. The solids will be guided upward by the screw rod 25 into the solids collection mechanism 18 for unified collection. The separated liquid continues to be further filtered in the filter device 15. The diameter of the holes in the filter cover 19 decreases sequentially, allowing multiple first filter mechanisms 13 to pass through. 3. The filtration process is carried out in stages. The filtered liquid is guided by the guiding mechanism 8 into the second filtration mechanism 9, where it is filtered through the activated carbon filter plate 30. High-quality coconut shell activated carbon filter plate 30 is selected here, which has a rich microporous structure and a large specific surface area, and can effectively adsorb fine particles, organic matter and odors in the sewage. When the liquid passes through the activated carbon filter plate 30, the particles are adsorbed and intercepted by the activated carbon, realizing fine filtration of sewage. The water after particle filtration then enters the sterilization tank 10 and is sterilized by the sterilization mechanism 11. The submersible germicidal lamp used in the sterilization mechanism 11 is the Chuanghuan brand CUV-300. The submersible ultraviolet germicidal lamp 21 emits ultraviolet light after water enters the sterilization chamber 10. The ultraviolet light destroys the DNA or RNA structure of bacteria, viruses and other microorganisms, making them inactive, thereby effectively sterilizing the water and ensuring that the treated water meets the corresponding hygiene standards. When the liquid level inside the sterilization chamber 10 reaches a certain speed, it will be discharged through the siphon drain pipe 12.

[0032] In this embodiment, a display 4 is installed on the upper side of the controller 3, and control buttons 5 are installed on the upper side of the controller 3 below the display 4. The display 4 on the controller 3 is used to display the real-time operating status and various parameters of the sewage treatment device 1, such as liquid level, filtration efficiency, sterilization time, etc., so that the operator can intuitively understand the working status of the equipment. The control buttons 5 are used by the operator to input commands to control the equipment, such as start, stop, and adjust the processing speed. Through the cooperation of the display 4 and the control buttons 5, human-machine interactive control of the sewage treatment device 1 is realized.

[0033] In this embodiment, the filtration device 15 consists of a base 14, a transmission mechanism 22, first filtration mechanisms 13, and a guide mechanism 8. Multiple first filtration mechanisms 13 and guide mechanisms 8 are mounted at their bottom ends on the upper side of the base 14. The bottom ends of the first filtration mechanisms 13 and guide mechanisms 8 are connected via the transmission mechanism 22. The first filtration mechanisms 13 are connected to each other and to the storage tank 2 via conduits 16. A motor 23 is installed inside the base 14 at the bottom end of each first filtration mechanism 13. Driven by the motor 23, the bottom ends of the first filtration mechanisms 13 and guide mechanisms 8 are connected via the transmission mechanism 22, enabling them to operate simultaneously. The first filtration mechanisms 13 are connected to each other and to the storage tank 2 via conduits 16, which are made of corrosion-resistant PVC. Made of materials that ensure no leakage occurs during wastewater transport, when the screw 25 of the first filtration mechanism 13 rotates, a negative pressure is generated in the conveying cylinder 24, thereby drawing the wastewater from the storage tank 2 into the conveying cylinder 24. Driven by the screw 25, the wastewater passes through the filter cover 19 installed in the section of the conveying cylinder 24 located inside the water tank 17. The diameter of the holes in the filter cover 19 decreases sequentially, allowing for staged filtration through multiple first filtration mechanisms 13, effectively separating solid impurities from the wastewater. The guiding mechanism 8 is responsible for guiding the liquid after preliminary filtration by the first filtration mechanism 13 to the second filtration mechanism 9. Its screw 25 is also driven by the transmission mechanism 22, and the liquid flows smoothly to the second filtration mechanism 9 through a screw conveyor, preparing for subsequent fine filtration.

[0034] In this embodiment, both the first filtration mechanism 13 and the guide mechanism 8 are composed of a feeding cylinder 24 and a screw rod 25. The feeding cylinder 24 is installed at the upper end of the base 14, and the screw rod 25 is rotatably installed inside the feeding cylinder 24. A water tank 17 is installed on the outer side of the feeding cylinder 24 on the upper side of the first filtration mechanism 13. A filter cover 19 is installed on the section of the feeding cylinder 24 inside the water tank 17. The end of the feeding cylinder 24 at the upper end of the first filtration mechanism 13 is connected to the solid collection mechanism 18. The end of the feeding cylinder 24 of the guide mechanism 8 is installed on the upper side of the second filtration mechanism 9.

[0035] In this embodiment, the transmission mechanism 22 consists of a synchronous belt 28, synchronous pulleys 26, and guide pulleys 27. The synchronous pulleys 26 are installed at the bottom of the spiral rod 25, and the guide pulleys 27 are installed on both sides between the synchronous pulleys 26. The synchronous belt 28 is wound around the outside of the synchronous pulleys 26 and the guide pulleys 27. When the motor 23 drives one of the synchronous pulleys 26 to rotate, the power is transmitted to the other synchronous pulleys 26 through the synchronous belt 28, so that all the spiral rods 25 rotate synchronously. The guide pulleys 27 are installed on both sides between the synchronous pulleys 26 to guide the synchronous belt 28 and ensure that the synchronous belt 28 can be stably wound on the synchronous pulleys 26, thus ensuring the stability and reliability of power transmission.

[0036] In this embodiment, a water inlet pipe 6 is installed on one side of the upper end of the storage tank 2, and an electronic level gauge 7 is installed at the upper end of the storage tank 2. The bottom end of the electronic level gauge 7 extends into the interior of the storage tank 2. The water inlet pipe 6 is used to guide sewage into the storage tank 2, and the electronic level gauge 7 is used to monitor the liquid level inside the storage tank 2.

[0037] In this embodiment, the sterilization mechanism 11 consists of a mounting base 20 and a submersible ultraviolet germicidal lamp 21. The mounting base 20 is installed at the upper end of the sterilization chamber 10, and the submersible ultraviolet germicidal lamp 21 is installed at the bottom end of the mounting base 20. The bottom end of the submersible ultraviolet germicidal lamp 21 extends into the interior of the sterilization chamber 10. When sewage enters the sterilization chamber 10, the ultraviolet germicidal lamp emits ultraviolet light. The sterilization effect of ultraviolet light destroys the DNA or RNA structure of bacteria, viruses and other microorganisms, making them inactive, thereby achieving the purpose of killing harmful microorganisms and ensuring that the treated sewage meets hygiene standards.

[0038] In this embodiment, the solid collection mechanism 18 consists of a collection box 32 and a conical cover 31. The conical cover 31 is installed at the upper end of the solid collection mechanism 18, located below the outlet end of the first filter mechanism 13. The collection box 32 is placed inside the solid collection mechanism 18, located below the conical cover 31. When the first filter mechanism 13 transports the separated solid impurities to the end, the solid impurities fall into the collection box 32 below through the conical cover 31. The conical cover 31 guides the solid impurities to fall, ensuring that the solid impurities can accurately enter the collection box 32. The collection box 32 is used to collect solid impurities in a concentrated manner, which facilitates subsequent cleaning and treatment of the solid impurities.

[0039] In this embodiment, the second filtration mechanism 9 consists of a filter box 29 and an activated carbon filter plate 30. The filter box 29 is installed at the upper end of the sterilization box 10, and the activated carbon filter plate 30 is installed inside the filter box 29. The filter box 29 is connected to the upper end of the guide mechanism 8, and a through connection is made between the bottom side of the filter box 29 and the upper end of the sterilization box 10. The activated carbon filter plate 30 inside the filter box 29 has a strong adsorption effect, which can adsorb fine impurities, organic matter, odors, etc. in the sewage, and further finely filter the sewage. The sewage filtered by the activated carbon filter plate 30 flows into the sterilization box 10 from the bottom side of the filter box 29 for subsequent sterilization treatment. In this way, the sewage treatment effect is improved, and the final discharged sewage is cleaner.
