Description

Technical Field

[0001] The present invention relates to the technical field of sewage treatment, and particularly to a sewage treatment device for infectious disease medical treatment. Background Art

[0002] A sewage treatment device for infectious disease medical treatment refers to a special device that targets the sewage containing infectious pathogens generated in places such as hospitals and infectious disease prevention and control institutions, and effectively removes or inactivates pathogenic microorganisms and toxic and harmful substances in the sewage through physical, chemical, biological and other processes (such as precipitation, filtration, disinfection, inactivation, etc.). If such sewage is directly discharged without treatment, the pathogens therein may spread through water bodies, soil and other channels, leading to the spread of infectious diseases, threatening public health and the safety of the ecological environment. Standard treatment can effectively kill pathogens, reduce the concentration of pollutants, prevent the spread of diseases and environmental pollution, ensure the health of the surrounding population and the safety of the water ecosystem, and at the same time is a necessary measure to implement environmental protection regulations and prevent the spread of medical pollution.

[0003] For the treatment of sewage from infectious disease medical treatment, usually, filtration is first carried out to remove solid impurities. After the solid impurities are removed, ozone and chlorine dioxide are injected into the filtered liquid to disinfect the filtered wastewater. After treatment, the treated wastewater is passed through an activated carbon treatment tank, a microfiltration + reverse osmosis composite treatment tank, and an ultraviolet sterilization device in sequence through a booster pump to further purify the sewage and improve the sewage treatment effect.

[0004] In the prior art, during the process of injecting ozone and chlorine dioxide into the liquid after solid impurity filtration, a fixed ventilation pipe is usually used to directly transport the gas into the liquid, and a stirring device is used to stir the liquid. The injection of the gas is usually continuous, and with the stirring of the stirring device, the gas is transported to all parts of the liquid to ensure the mixing of the liquid and the gas. However, during continuous supply, if the pollutant concentration in the waste liquid has been significantly reduced, due to insufficient gas-liquid fusion, excessive ozone and chlorine dioxide will decompose by themselves because there is no target substance to react with, resulting in waste of the reagent. At the same time, a saturated layer of reagent concentration is easily formed near the gas-liquid interface, hindering further mass transfer.

[0005] For this, we propose a sewage treatment device for infectious disease medical treatment. Summary of the Invention

[0019] The present invention has the following beneficial effects: 1. For the medical sewage treatment equipment for infectious diseases, through the design of the telescopic air outlet assembly, precise gas discharge is synchronously realized when the stirring rod rotates, and the stirring kinetic energy is used to drive the ventilation cylinder to move along a specific track. When the telescopic housing is compressed, the driving block jacks up the driving rod, triggering the opening of the one-way ventilation valve, so that ozone or chlorine dioxide gas is intermittently and evenly discharged. This design avoids the problem of uneven gas distribution caused by continuous air supply in the traditional aeration system. At the same time, through the one-way closing characteristic of the valve, liquid backflow is prevented from damaging the gas source equipment. Through the synergistic effect of periodic ventilation and the cutting assembly, the gas-liquid mixing efficiency is further enhanced.

[0020] 2. For this medical sewage treatment equipment for infectious diseases, through the mechanical coupling of the pulling member, the inner slider and the spiral track groove, the cutting blade is driven to rotate at high speed instantly when the ventilation valve is opened, reducing the particle size of the discharged bubbles.

[0021] 3. For this medical sewage treatment equipment for infectious diseases, through the periodic expansion and contraction of the telescopic housing to drive the engagement of the tooth block and the gear, under the action of the energy storage and release of the torsion spring, the striking rod continuously impacts the inner wall of the stirring rod, making the vibration directly act on the discharged gas, and the originally larger bubbles can be quickly broken into smaller bubbles. A smaller bubble particle size means a larger gas-liquid contact surface area, thus significantly improving the mass transfer efficiency of gas molecules and pollutants in the liquid and accelerating the reaction rate of agents such as ozone and chlorine dioxide.

[0024] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0025] The purpose of this embodiment is to promote the solution of the problem that continuous gas supply will cause excessive gas to decompose by itself due to the lack of target substances to react, resulting in waste of chemicals. Please refer to Figures 1 to 10 , an infectious disease medical sewage treatment device, including a sewage treatment device 1, which is used for filtering medical sewage containing infectious diseases. The sewage treatment device 1 includes a filter, a disinfection reaction housing 11, an activated carbon filtration pool, a reverse osmosis composite treatment pool, and an ultraviolet sterilization device.

[0026] A stirring shaft 15 and a stirring rod 17 are arranged in the disinfection reaction housing 11. The stirring shaft 15 and the stirring rod 17 are fixedly connected. An installation groove 18 is arranged in the stirring shaft 15. The installation groove 18 is communicated with the ozone gas channel 13 and the chlorine dioxide gas channel 14. The stirring shaft 15 and the stirring rod 17 are used for stirring the waste liquid.

[0027] A sewage channel 12, an ozone gas channel 13, and a chlorine dioxide gas channel 14 are arranged at the top of the disinfection reaction housing 11. A driving motor 16 is installed at the bottom of the disinfection reaction housing 11. The output end of the driving motor 16 is fixedly connected to a stirring shaft 15.

[0028] The sewage treatment device 1 treats the sewage generated during the treatment of infectious diseases through multi-stage disinfection treatment and multi-stage filtration processes. When the treated sewage reaches the safe discharge standard, the treated sewage is discharged. At the same time, during the treatment process, automatic control is carried out through the PLC to avoid secondary transmission of pollution sources caused by manual operation, reduce the transmission routes of pathogens, and ensure the physical health of the staff.

[0029] Before the medical sewage passes through the filter, primary pretreatment is carried out to ensure the killing of infectious pathogenic bacteria entering the wastewater treatment system and ensure the safety of personnel. After the solid impurities in the sewage are removed by the filter, secondary disinfection is carried out to fully sterilize. The sewage entering the disinfection reactor is subjected to sterilization and disinfection treatment under the dual action of ozone and chlorine dioxide. The treated sewage passes through a booster pump and then passes through an activated carbon filter tank, a microfiltration + reverse osmosis composite treatment tank, and an ultraviolet sterilization device in sequence to achieve further purification treatment of the sewage and improve the treatment effect of the sewage.

[0030] The sewage treatment device 1 integrates the ozone gas channel 13 and the chlorine dioxide gas channel 14 in the stirring shaft 15, so that the discharge of gas can be transported to various parts of the liquid as the position of the stirring rod 17 changes, thereby improving the coverage range of the gas. At the same time, as the stirring device drives the flow of the liquid, the coverage range of the gas is further expanded, thereby improving the purification efficiency of the waste liquid.

[0031] A telescopic air outlet component 2 is arranged in the stirring rod 17. The telescopic air outlet component 2 is used to control the discharge frequency of the gas. The telescopic air outlet component 2 includes a telescopic housing 21 arranged on the outer side of the stirring rod 17. A ventilation cylinder 27 is arranged on one side of the telescopic housing 21, and a one-way ventilation valve 28 is installed in the ventilation cylinder 27.

[0032] The telescopic housing 21 is slidably connected to the outer side wall of the stirring rod 17. A connecting rod 22 is fixedly connected inside the telescopic housing 21. The stirring rod 17 and the telescopic housing 21 are connected by a telescopic spring 23. One end of the connecting rod 22 is slidably connected in the telescopic driving groove 24. The telescopic driving groove 24 is used to drive the connecting rod 22 to slide inside the telescopic housing 21. The telescopic driving groove 24 is opened on the side wall of the fixed rod 26. The fixed rod 26 is arranged in the installation groove 18, and the top of the fixed rod 26 is fixedly connected to the inner wall of the disinfection reaction housing 11.

[0033] A cross mounting frame 25 is fixedly connected to one side of the stirring rod 17, and the connecting rod 22 is slidably connected inside the cross mounting frame 25.

[0034] A driving rod 29 is installed in the one-way ventilation valve 28. The bottom of the driving rod 29 is designed with an inclined surface. The inclined surface of the driving rod 29 abuts against a driving block 210, and the driving block 210 is fixedly connected to one end of the stirring rod 17.

[0035] The telescopic air outlet assembly 2 drives the telescopic shell 21 to slide along the outer wall of the stirring rod 17 through the rotation of the stirring rod 17, and utilizes the trajectory movement of one end of the connecting rod 22 slidingly connected to the telescopic driving groove 24 of the fixed rod 26, so that the telescopic shell 21 can be periodically extended and retracted through the telescopic spring 23. When the stirring rod 17 rotates, the telescopic shell 21 is compressed when it is close to one side of the stirring rod 17, driving the ventilator 27 to move. At this time, the inclined surface of the driving rod 29 in the one-way vent valve 28 contacts the driving block 210 on the stirring rod 17, and the driving rod 29 is lifted up to open the one-way vent valve 28. The one-way vent valve 28 is formed by the base, The telescopic housing 21 is composed of a spring and a sealing plate, and the driving rod 29 is fixedly connected to the sealing plate. When the telescopic housing 21 slides to the left, the bottom of the driving rod 29 conflicts with the driving block 210, thereby driving the driving rod 29 and the sealing plate fixedly connected thereto to slide upward, so that the one-way vent valve 28 opens, and ozone and chlorine dioxide gases are discharged from the mounting groove 18 through the vent tube 27; when the telescopic housing 21 rotates away from the stirring rod 17 along with the stirring rod 17, the telescopic spring 23 resets to extend the telescopic housing 21, the driving rod 29 disengages from the driving block 210, and the one-way vent valve 28 closes to stop the gas supply, thereby realizing intermittent discharge of the gas.

[0036] This intermittent gas supply design can avoid the waste of reagents caused by excessive gas decomposition due to no target reaction caused by continuous gas supply; when the gas supply is intermittent, the liquid turbulence is weakened during the stop phase, and large bubbles float up and leave the system. After the gas supply is restarted, the newly generated small bubbles can be more evenly dispersed, increasing the gas-liquid contact area and improving the mixing efficiency of gas and liquid; the rotation of the stirring rod 17 allows the gas to be periodically released at different positions, thereby enhancing the uniformity of gas-liquid mixing and the dynamic mass transfer effect, breaking the concentration saturation layer at the gas-liquid interface, and improving the sterilization efficiency.

[0037] A cutting assembly 3 is provided in the vent cylinder 27 for cutting the exhausted bubbles. The cutting assembly 3 includes a mounting rotation groove 31 provided in the vent cylinder 27 , a rotating shaft 32 is rotatably connected in the mounting rotation groove 31 , and a cutting blade 33 is fixedly connected to the top of the rotating shaft 32 .

[0038] An inner groove 34 and a track groove 36 are provided in the rotating shaft 32. An inner slider 35 is slidably connected in the inner groove 34. A track slider 37 is fixedly connected to the side wall of the inner slider 35. The track slider 37 is slidably connected in the track groove 36. The inner slider 35 and the mounting rotating groove 31 are connected via a return spring 310.

[0039] A connecting groove 39 is provided in the ventilator 27, and a pulling member 38 is provided in the connecting groove 39. One end of the pulling member 38 is fixedly connected to the bottom of the inner slider 35, and the other end of the pulling member 38 is fixedly connected to the one-way vent valve 28. The pulling member 38 includes a rectangular block and a pulling rope.

[0040] When the stirring rod 17 rotates to a specific position with the stirring shaft 15, the telescopic shell 21 is compressed due to the track movement of the connecting rod 22 in the telescopic driving groove 24, driving the vent tube 27 to move toward the stirring rod 17. At this time, the inclined surface of the driving rod 29 in the one-way vent valve 28 contacts the driving block 210 at the end of the stirring rod 17. The driving block 210 lifts the driving rod 29 along the inclined surface to open the one-way vent valve 28, and the ozone or chlorine dioxide gas is discharged from the installation groove 18 through the vent tube 27. When the one-way vent valve 28 is opened, the pulling member 38 is tightened as the driving rod 29 moves upward, pulling the inner slider 35 to slide downward along the inner groove 34 of the rotating shaft 32, and the track slider 37 on the side wall of the inner slider 35 moves along the track groove 36. Since the track groove 36 is designed in a spiral shape, the linear motion of the track slider 37 is converted into the circular motion of the rotating shaft 32, and the cutting blade 33 at the top of the rotating shaft 32 rotates synchronously. The blade intersects the bubble discharge path at right angles, forming a shear force when the bubbles pass through the outlet of the vent tube 27. The cutting blade 33 can adopt a serrated or multi-blade structure, combined with the centrifugal force generated by high-speed rotation, to quickly tear the bubbles into bubble groups with smaller diameters. When the stirring rod 17 continues to rotate, the telescopic shell 21 extends and resets, the one-way vent valve 28 is closed, the pulling piece 38 relaxes, and the inner slider 35 is reset to the initial position under the action of the reset spring 310, and the rotating shaft 32 rotates in the opposite direction to reset. During this process, the special curve design of the track groove 36 ensures that the rotating shaft 32 rotates forward to cut bubbles when the one-way vent valve 28 is opened, and resets smoothly when closed to avoid jamming or excessive wear. At the same time, the pulling piece 38 is composed of a rectangular block and a pulling rope, and the connecting groove 39 also has a rectangular cross-section. The setting of the rectangular block and the rectangular connecting groove 39 ensures that the inner slider 35 will not rotate during the sliding process.

[0041] The advantages of this design are: the minimized bubbles can greatly increase the gas-liquid contact surface area, improve the reaction efficiency of ozone and chlorine dioxide with pathogens and pollutants in sewage, and significantly enhance the mass transfer effect per unit volume of gas, thereby achieving more thorough sterilization and decomposition of pollutants at the same dosage of reagents; small-size bubbles rise slowly and stay for a long time in the liquid, and can make full use of the turbulent environment formed by stirring to evenly diffuse to all areas of the liquid, avoiding the problem of saturated layer concentration at the gas-liquid interface caused by the rapid floating of large bubbles, and further improving the utilization rate of reagents; the refined bubbles can also reduce the load of subsequent activated carbon adsorption, reverse osmosis and other treatment links, making the entire sewage treatment process more efficient and coordinated, while ensuring the treatment effect, reducing reagent consumption and equipment operating costs, and achieving energy-saving and precise treatment of infectious medical sewage.

[0042] A vibration hitting component 4 is provided at the bottom of the stirring rod 17. The vibration hitting component 4 is used to hit the stirring rod 17. The vibration hitting component 4 includes a mounting rod 41 fixedly connected to the side wall of the stirring shaft 15. A fixed shaft 42 is mounted on one side of the mounting rod 41. A gear 44 is mounted on the side wall of the fixed shaft 42. A hitting rod 46 is fixedly connected to the side wall of the gear 44.

[0043] The fixed shaft 42 and the gear 44 are connected by a torsion spring 43. The gear 44 is meshed with a tooth block 45. The tooth block 45 is fixedly connected to the bottom of the telescopic housing 21.

[0044] When the telescopic housing 21 rotates with the stirring rod 17 to a position away from the fixed rod 26, the telescopic housing 21 is pushed to extend outwards, and the tooth block 45 gradually disengages from the gear 44. At this time, the torsion spring 43 releases its elastic potential energy, driving the gear 44 to rotate rapidly in the reverse direction. The hitting rod 46 fixed to the side wall of the gear 44 impacts the stirring rod 17 due to the action of centrifugal force and the restoring force of the torsion spring 43, generating vibrations and transmitting them to the ventilation cylinder 27. As the stirring shaft 15 continues to rotate, the telescopic housing 21 continuously repeats the telescopic action, and the tooth block 45 periodically meshes with and disengages from the gear 44, causing the hitting rod 46 to reciprocally hit the ventilation cylinder 27 at a fixed frequency, forming regular vibrations. The hitting rod 46 is made of flexible rubber material, and this material of the hitting rod 46 can ensure that during the hitting process, it will not affect the rotation of the gear 44.

[0045] The advantage of this design is that the vibration of the ventilation cylinder 27 directly acts on the discharged gas, which can quickly break large bubbles into small bubbles. A smaller bubble diameter means a larger gas-liquid contact surface area, thereby significantly improving the mass transfer efficiency between gas molecules and pollutants in the liquid, accelerating the reaction rate of agents such as ozone and chlorine dioxide. In addition, the high-frequency disturbance of the vibration can inhibit the rapid coalescence of bubbles after discharge, maintaining the dispersion stability of the bubble group and further extending the effective mass transfer time.

[0046] Through the vibration of the telescopic housing 21 containing the ventilation cylinder 27, the position of the ventilation cylinder 27 changes periodically with the vibration, enabling the gas to be discharged not to concentrate in a certain fixed area of the ventilation cylinder 27, but to be dispersed to different depths and orientations of the liquid in a dynamic trajectory, avoiding the rapid saturation of the agent concentration near the gas-liquid interface in this area due to the continuous emergence of gas from the same position, forming a mass transfer resistance layer. This dispersed discharge mechanism can promote the more uniform diffusion of gas in the turbulence formed by stirring, making the contact opportunities between agents such as ozone and chlorine dioxide and pollutants in the liquid tend to be balanced, preventing the decomposition and waste of excessive unreacted agents in local areas, and at the same time improving the overall gas-liquid mass transfer efficiency, reducing "concentration dead corners" and "dead volumes", and ensuring the uniformity and high efficiency of the disinfection or reaction process.

[0047] It should be noted that in this text, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements not only includes those elements, but also includes other elements not expressly listed, or elements inherent to such process, method, article or device.

[0048] The above are only the preferred embodiments of the present invention. It should be pointed out that for those of ordinary skill in the art, without departing from the technical principle of the present invention, several improvements and modifications can be made, and these improvements and modifications should also be regarded as the protection scope of the present invention.
