Description

Technical Field

[0001] The present invention relates to the technical field of sewage treatment, in particular to infectious disease medical sewage treatment equipment. Background Art

[0002] An infectious disease medical wastewater treatment equipment refers to a special equipment that effectively removes or inactivates pathogenic microorganisms and toxic and harmful substances in wastewater containing infectious pathogens generated in hospitals, infectious disease prevention and control institutions and other places through physical, chemical, biological and other processes (such as sedimentation, filtration, disinfection, inactivation, etc.). If this type of wastewater is discharged directly without treatment, the pathogens in it may spread through water bodies, soil and other channels, leading to the spread of infectious diseases and threatening public health and ecological environmental safety. Standardized treatment can effectively kill pathogens, reduce pollutant concentrations, prevent disease transmission and environmental pollution, and protect the health of surrounding people and the safety of water ecosystems. It is also a necessary measure to implement environmental protection laws and regulations and prevent the spread of medical pollution.

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

[0004] In the prior art, during the process of injecting ozone and chlorine dioxide into the liquid after filtering out solid impurities, a fixed ventilation pipe is usually used to directly transport the gas into the liquid, and the liquid is stirred by a stirring device. The injection of gas is usually continuous, and as the stirring device stirs, the gas is transported to various parts of the liquid. However, during continuous supply, if the concentration of pollutants in the waste liquid has been significantly reduced, the gas-liquid fusion will be insufficient, resulting in excessive ozone and chlorine dioxide self-decomposing due to the lack of target substances to react, resulting in a waste of reagents. At the same time, a saturated layer of reagent concentration is easily formed near the gas-liquid interface, hindering further mass transfer.

[0005] In this regard, we propose an infectious disease medical wastewater treatment equipment. Summary of the Invention

[0019] The present invention has the following beneficial effects:

[0020] 1. This infectious disease medical wastewater treatment equipment, through the design of a telescopic air outlet component, achieves precise gas discharge synchronously with the rotation of the stirring rod. The stirring kinetic energy is used to drive the vent cylinder along a specific trajectory. When the telescopic shell is compressed, the drive block lifts the drive rod, triggering the one-way vent valve to open, allowing ozone or chlorine dioxide gas to be discharged intermittently and evenly. This design avoids the uneven gas distribution problem caused by the continuous air supply of traditional aeration systems. At the same time, the one-way closing feature of the valve prevents liquid backflow from damaging the gas source equipment. The synergistic effect of periodic ventilation and the cutting component further enhances the gas-liquid mixing efficiency.

[0021] 2. This infectious disease medical wastewater treatment equipment, through the mechanical coupling of the pulling member, the inner slider and the spiral track groove, drives the cutting blade to rotate at high speed at the moment the vent valve is opened, thereby reducing the particle size of the discharged bubbles. The cutting blade adopts a serrated multi-blade structure, combining the dual effects of centrifugal force and shear force to increase the gas-liquid contact area and significantly enhance the mass transfer efficiency of disinfectants such as ozone.

[0022] 3. This infectious disease medical wastewater treatment equipment drives the tooth block and gear to engage through the periodic expansion and contraction of the telescopic shell. Under the action of the torsion spring energy storage release, the striking rod continuously impacts the inner wall of the stirring rod, so that the vibration directly acts on the discharged gas, which can quickly break the originally large bubbles into small bubbles. The smaller bubble particle size means a larger gas-liquid contact surface area, thereby significantly improving the mass transfer efficiency between gas molecules and pollutants in the liquid, and accelerating the reaction rate of agents such as ozone and chlorine dioxide.

DETAILED DESCRIPTION

[0034] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0035] This embodiment is intended to solve the problem that continuous gas supply will cause excessive gas to decompose due to lack of target substances to react, resulting in waste of reagents. Figures 1 to 10 A medical wastewater treatment device for infectious diseases includes a wastewater treatment device 1, which is used to filter and treat medical wastewater for infectious diseases. The wastewater treatment device 1 includes a filter, a disinfection reaction shell 11, an activated carbon filter pool, a reverse osmosis composite treatment pool and an ultraviolet sterilization device.

[0036] A stirring shaft 15 and a stirring rod 17 are provided in the disinfection reaction shell 11. The stirring shaft 15 and the stirring rod 17 are fixedly connected. A mounting groove 18 is provided in the stirring shaft 15. The mounting groove 18 is connected to the ozone gas channel 13 and the chlorine dioxide gas channel 14. The stirring shaft 15 and the stirring rod 17 are used to stir the waste liquid.

[0037] A sewage channel 12 , an ozone gas channel 13 and a chlorine dioxide gas channel 14 are provided on the top of the disinfection reaction shell 11 . A drive motor 16 is installed on the bottom of the disinfection reaction shell 11 , and a stirring shaft 15 is fixedly connected to the output end of the drive motor 16 .

[0038] The sewage treatment device 1 treats the sewage generated during the treatment of infectious diseases through multi-stage disinfection and multi-stage filtration processes, so that the treated sewage is discharged when it meets the safe discharge standards. At the same time, the PLC is used for automatic control during the treatment process to avoid secondary transmission of pollution sources caused by human operation, reduce the transmission path of pathogens, and ensure the health of staff.

[0039] Medical wastewater undergoes primary pretreatment before passing through the filters to eliminate infectious pathogens that could enter the wastewater treatment system, ensuring personnel safety. After solid impurities are removed by the filters, secondary disinfection is performed to fully sterilize the wastewater. Once entering the disinfection reactor, the wastewater undergoes a dual sterilization treatment using ozone and chlorine dioxide. The treated wastewater is then pumped through an activated carbon filtration tank, a microfiltration and reverse osmosis combined treatment tank, and an ultraviolet disinfection device, further purifying the wastewater and improving its treatment efficiency.

[0040] 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 gas discharge can be transported to various parts of the liquid as the position of the stirring rod 17 changes, thereby improving the gas coverage range. At the same time, as the stirring device drives the flow of the liquid, the gas coverage range is further expanded, thereby improving the purification efficiency of the waste liquid.

[0041] A telescopic air outlet assembly 2 is provided in the stirring rod 17, and the telescopic air outlet assembly 2 is used to control the gas discharge frequency. The telescopic air outlet assembly 2 includes a telescopic shell 21 arranged on the outside of the stirring rod 17, and a vent cylinder 27 is provided on one side of the telescopic shell 21, and a one-way vent valve 28 is installed in the vent cylinder 27.

[0042] The telescopic shell 21 is slidably connected to the outer wall of the stirring rod 17, and a connecting rod 22 is fixedly connected to the inside of the telescopic shell 21. The stirring rod 17 and the telescopic shell 21 are connected by a telescopic spring 23. One end of the connecting rod 22 is slidably connected to the telescopic drive groove 24. The telescopic drive groove 24 is used to drive the connecting rod 22 to slide in the telescopic shell 21. The telescopic drive groove 24 is opened on the side wall of the fixed rod 26. The fixed rod 26 is arranged in the mounting groove 18, and the top of the fixed rod 26 is fixedly connected to the inner wall of the disinfection reaction shell 11.

[0043] One side of the stirring rod 17 is fixedly connected to a cross mounting frame 25 , and the connecting rod 22 is slidably connected in the cross mounting frame 25 .

[0044] A driving rod 29 is installed in the one-way vent valve 28 . The bottom of the driving rod 29 is designed as an inclined surface. The inclined surface of the driving rod 29 abuts against a driving block 210 . The driving block 210 is fixedly connected to one end of the stirring rod 17 .

[0045] 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 realize periodic expansion and contraction through the telescopic spring 23. When the stirring rod 17 rotates, the telescopic shell 21 is compressed when it approaches one side of the stirring rod 17, driving the vent cylinder 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 connected to the base, It is composed of a spring and a sealing plate, and the driving rod 29 is fixedly connected to the sealing plate. When the telescopic shell 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 cylinder 27; when the telescopic shell 21 rotates away from the stirring rod 17 along with the stirring rod 17, the telescopic spring 23 resets to make the telescopic shell 21 extend, 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 gas.

[0046] Through this intermittent gas supply design, the excessive gas caused by continuous gas supply and the decomposition and waste of reagents due to no target reaction is avoided; 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 the gas and liquid; the rotation of the stirring rod 17 is used to release the gas periodically at different positions, thereby enhancing the uniformity of the gas-liquid mixing and the dynamic mass transfer effect, breaking the concentration saturation layer at the gas-liquid interface, and improving the sterilization efficiency.

[0047] A cutting assembly 3 is provided in the vent cylinder 27, and the cutting assembly 3 is used to cut the discharged bubbles. The cutting assembly 3 includes an installation rotation groove 31 opened in the vent cylinder 27, a rotating shaft 32 is rotatably connected in the installation rotation groove 31, and a cutting blade 33 is fixedly connected to the top of the rotating shaft 32.

[0048] 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 by a reset spring 310.

[0049] A connecting groove 39 is provided in the vent cylinder 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.

[0050] When the stirring rod 17 rotates to a specific position along 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 cylinder 27 to move in the direction of 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 pushes up the driving rod 29 along the inclined surface, so that the one-way vent valve 28 is opened, and the ozone or chlorine dioxide gas is discharged from the installation groove 18 through the vent cylinder 27. At the same time as 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 spirally designed, 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 perpendicularly, forming a shear force when the bubbles pass through the outlet of the vent cylinder 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 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.

[0051] The advantages of this design are: the minimized bubbles can greatly increase the gas-liquid contact surface area, thereby improving the reaction efficiency of ozone and chlorine dioxide with pathogens and pollutants in sewage, and significantly enhancing 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-particle bubbles rise slowly in the liquid and stay for a long time, 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 gas-liquid interface concentration saturation layer 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 realizing energy-saving and precise treatment of infectious medical sewage.

[0052] A vibration striking assembly 4 is provided at the bottom of the stirring rod 17, and the vibration striking assembly 4 is used to strike the stirring rod 17. The vibration striking assembly 4 includes a mounting rod 41 fixedly connected to the side wall of the stirring shaft 15, and a fixed shaft 42 is installed on one side of the mounting rod 41. A gear 44 is installed on the side wall of the fixed shaft 42, and a striking rod 46 is fixedly connected to the side wall of the gear 44.

[0053] The fixed shaft 42 and the gear 44 are connected via a torsion spring 43 . The gear 44 is meshed with a gear block 45 . The gear block 45 is fixedly connected to the bottom of the telescopic housing 21 .

[0054] When the telescopic shell 21 rotates with the stirring rod 17 to a position away from the fixed rod 26, the telescopic shell 21 is pushed to extend outward, and the tooth block 45 is gradually disengaged 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 opposite direction, and the striking rod 46 fixed on the side wall of the gear 44 hits the stirring rod 17 due to the centrifugal force and the restoring force of the torsion spring 43, generating vibration and transmitting it to the ventilator 27. As the stirring shaft 15 continues to rotate, the telescopic shell 21 continuously repeats the telescopic action, and the tooth block 45 is periodically engaged and disengaged from the gear 44, so that the striking rod 46 reciprocates and strikes the ventilator 27 at a fixed frequency, forming regular vibration. The striking rod 46 is made of flexible rubber material. The striking rod 46 of this material can ensure that the rotation of the gear 44 will not be affected during the striking process.

[0055] The advantage of this design is that the vibration of the vent cylinder 27 directly acts on the discharged gas, which can quickly break the originally larger bubbles into small bubbles. The smaller bubble particle size means a larger gas-liquid contact surface area, thereby significantly improving the mass transfer efficiency between gas molecules and pollutants in the liquid, and 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 aggregation of bubbles after discharge, maintain the dispersion stability of the bubble group, and further extend the effective mass transfer time.

[0056] By vibrating the telescopic shell 21 containing the vent cylinder 27, the position of the vent cylinder 27 changes periodically with the vibration, so that the gas will no longer be concentrated in a fixed area of ​​the vent cylinder 27 when discharged, but will be dispersed to different depths and directions of the liquid with a dynamic trajectory, so as to avoid the rapid saturation of the concentration of the agent near the gas-liquid interface in the area due to the continuous outflow of gas from the same position, thereby forming a mass transfer resistance layer; this dispersed discharge mechanism can promote the gas to diffuse more evenly in the turbulence formed by stirring, so that the contact opportunities of agents such as ozone and chlorine dioxide with pollutants in the liquid tend to be balanced, and prevent local areas from being decomposed and wasted due to excessive unreacted agents. At the same time, improving the overall gas-liquid mass transfer efficiency can reduce "concentration dead corners" and "dead volumes", ensuring the uniformity and efficiency of the disinfection or reaction process.

[0057] It should be noted that, in this document, relational terms such as first and second, etc., are used only 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 terms "comprises," "comprising," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that includes a list of elements includes not only those elements but also other elements not explicitly listed, or elements inherent to such process, method, article, or apparatus.

[0058] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
