Description

Technical Field

[0001] This utility model belongs to the technical field of wastewater treatment devices, specifically, it relates to a non-powered disinfection device for medical wastewater. Background Technology

[0002] Medical wastewater refers to wastewater generated during medical activities that contains pathogenic microorganisms, harmful chemicals, or other pollutants. Medical wastewater may contain patient excrement, drug residues, disinfectants, blood, bodily fluids, bacteria, chemical reagents, etc., thus possessing high pollutant and infectious properties. Direct discharge without treatment poses a serious threat to the environment and public health. To ensure environmental safety and public health, medical wastewater requires professional treatment and disinfection to meet discharge standards before being released into water bodies.

[0003] A non-powered disinfection device for medical wastewater is a device that uses natural energy or physical principles to disinfect wastewater without requiring external power. Its main principles typically include using ultraviolet light, solar energy, chemical reactions, or natural sedimentation to kill pathogenic microorganisms and harmful substances in the wastewater.

[0004] Patent CN209161798U introduces a non-powered medical wastewater treatment device. It degrades and purifies wastewater through multi-stage vertically arranged biological module beds, combined packing materials, and inclined tube packing materials. It is supplemented by a turbine ventilator to achieve a negative pressure effect, improve air circulation, ensure the survival environment of aerobic bacteria, and improve the purification effect of wastewater. It solves the problems of existing medical wastewater treatment devices, such as complex process flow, high energy consumption, need for professional personnel to operate and maintain, large footprint, and high investment.

[0005] However, when the above-mentioned non-powered disinfection device for medical wastewater is used to treat large-flow or high-concentration wastewater, its treatment capacity is limited by the amount and quality of water due to its reliance on natural energy or physical means. When the wastewater flow is large or the pollutant concentration is high, the disinfection effect is easily affected, and it cannot effectively kill a large number of pathogenic microorganisms or remove harmful chemicals, which may lead to substandard wastewater treatment and thus pose potential risks to the environment and public health. Utility Model Content

[0006] This invention provides a non-powered disinfection device for medical wastewater, aiming to solve the technical problem that existing non-powered disinfection devices for medical wastewater, when treating large-flow or high-concentration wastewater, cannot effectively kill a large number of pathogenic microorganisms or remove harmful chemicals due to the use of non-powered wastewater purification methods and the reliance on degradation and packing purification methods for high-concentration medical wastewater, resulting in substandard wastewater treatment and potential risks to the environment and public health.

[0007] The objective of this utility model can be achieved through the following technical solutions:

[0008] A non-powered disinfection device for medical wastewater includes a shell, with a long pipe connected to the center of the upper surface of the shell; a conical tube is fixedly connected to the upper end of the long pipe and they are interconnected; an arc-shaped guide plate in a circular array is provided on the upper part of the inner surface of the conical tube; a conical baffle is fixedly provided on the arc-shaped guide plate; a conical guide plate is provided on the top of the conical baffle; the conical baffle and the conical guide plate are fixedly connected; an auger is provided in the long pipe at the lower end of the conical tube; and a water outlet pipe is provided at the bottom side wall of the shell.

[0009] Furthermore, a second flange is fixedly connected to the upper end of the cone; a first flange is bolted to the second flange; a sealing cover is fixedly attached to the upper surface of the first flange; and a connected water inlet pipe is fixedly attached to the upper surface of the sealing cover.

[0010] Furthermore, a processing chamber is provided inside the shell; three vertically arranged biological module beds are fixedly connected inside the shell.

[0011] Furthermore, the shell has through slots corresponding to the positions at both ends of the bio-module bed.

[0012] Furthermore, each bio-module bed has an L-shaped plate fixed to one end, and the two sides of the L-shaped plate are connected to the bio-module bed and the inner wall of the shell, respectively.

[0013] Furthermore, the adjacent L-shaped plates are arranged in an alternating pattern.

[0014] Furthermore, a flow guide plate is fixedly installed inside the processing chamber, with the upper part of the flow guide plate located directly below the long tube and the lower part of the flow guide plate located above the L-shaped plate fixed to the end of the uppermost bio-module bed.

[0015] Furthermore, the upper surface of the shell is provided with a circular array of uprights; a reflector is provided at the top of the uprights.

[0016] Furthermore, hinge blocks are fixed to the bottom and middle of the lower surface of the reflector; the hinge block in the middle is rotatably connected to the top of the upright; and a diagonal brace is rotatably connected to the hinge block at the bottom.

[0017] Furthermore, a rack is fixedly connected to the side of the upright near the hinge block; the bottom end of the diagonal brace abuts against the rack.

[0018] The beneficial effects of this utility model are:

[0019] 1) This utility model provides a circular array of arc-shaped guide plates on the upper part of the inner surface of the cone, along with a conical baffle and a conical guide plate. This allows medical wastewater and clean water to flow downwards along the arc-shaped guide plates under the guidance of the conical guide plates. Due to the inertia and tortuous shape of the water flow, the wastewater is forced to rotate downwards along the curved trajectory of the guide plates during the flow, generating a vortex effect and thus forming a vortex. The vortex makes the flow of water more complex, and the water and waste liquid can be mixed and diluted under the action of the vortex, which helps to improve the degradation efficiency of pollutants in the water.

[0020] 2) This utility model, by setting an auger inside a long pipe, makes the wastewater descend in a spiral on the surface of the auger blades, which not only extends the flow path of the wastewater, but also improves the mixing effect of the wastewater and the water body, resulting in better subsequent treatment effect.

[0021] 3) The cone, long tube, and auger in this utility model are all made of transparent materials. The top of the uprights in the circumferential array on the upper surface of the shell are all equipped with reflectors. The reflectors increase the concentration of sunlight, thereby increasing the intensity of sunlight irradiation on the cone and long tube. During the flow of medical wastewater, sunlight can pass through the cone and long tube to disinfect the medical wastewater inside with ultraviolet light, thus improving the disinfection effect.

[0032] Three biological module beds 20 divide the treatment chamber 2 into four parts; a guide plate 21 is fixedly installed in the uppermost treatment chamber 2, with the upper part of the guide plate 21 located directly below the long pipe 11 and the lower part of the guide plate 21 located above the L-shaped plate 19 fixed to the end of the uppermost biological module bed 20; the two end faces of the guide plate 21 are fixedly connected to the front and rear inner walls of the shell 1 respectively; a water outlet pipe 18 is provided on the shell 1 corresponding to the position of the side wall of the bottommost treatment chamber 2.

[0033] Please see Figure 2 and Figure 3 As shown, an auger 12 is installed inside the long tube 11 connected to the upper surface of the shell 1; a fixing ring 10 is respectively installed near the two ends of the auger 12, and the auger 12 is rotatably connected to the fixing ring 10; the fixing ring 10 is fixedly connected to the inner wall of the long tube via a connecting rod; an arc-shaped guide plate 9 in a circular array is installed on the upper part of the inner surface of the cone 8 for guiding the flow, so that the liquid forms a vortex in the lower part of the cone 8; a conical baffle 7 is fixedly installed on the arc-shaped guide plate 9; a conical guide plate 71 is installed on the top of the conical baffle 7, which is used to guide the sewage to the top of the arc-shaped guide plate 9, so that the sewage flows along the arc-shaped guide plate 9; the conical baffle 7 is connected to the conical guide plate 71.

[0034] Please see Figure 1 and Figure 4 As shown, the upper surface of the housing 1 is also provided with a circular array of uprights 15; a reflector 13 is provided at the top of the uprights 15; a hinge block 14 is fixedly connected to the bottom and middle of the lower surface of the reflector 13; the hinge block 14 located in the middle is rotatably connected to the top of the uprights 15; a diagonal brace 16 is rotatably connected to the hinge block 14 located at the bottom; a rack 17 is fixedly connected to the side of the uprights 15 near the hinge block 14; the bottom end of the diagonal brace 16 abuts against the rack 17, and the angle of the reflector 13 can be adjusted by moving the diagonal brace 16 up and down to change the position of the bottom end abutting against the rack 17.

[0035] To facilitate understanding of the above-mentioned technical solution of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below:

[0036] In use, a large amount or high concentration of medical wastewater and dilution water enter together through the inlet pipe 3 and then flow onto the conical guide plate 71. Because the conical baffle plate 7 is fixedly connected below the conical guide plate 71, the water does not flow directly down. Under the guidance of the conical guide plate 71, the medical wastewater flows downward along the arc-shaped guide plate 9. Due to the inertia and tortuous shape of the water flow, the wastewater is forced to rotate downward along the curved trajectory of the guide plate during the flow, generating a vortex effect and thus forming a vortex. The vortex makes the flow of water more complex, and the water and waste liquid can mix and dilute under the action of the vortex, which helps to improve the degradation efficiency of pollutants in the water.

[0037] Furthermore, the medical wastewater continues to flow downwards to the long pipe 11. Since the long pipe 11 is connected to a rotating auger 12, the wastewater will spiral down on the surface of the auger 12 blades, which not only extends the flow path of the wastewater, but also improves the mixing effect of the wastewater and the water body, making the subsequent treatment effect better.

[0038] In this embodiment, the cone 8, the long cylinder, and the auger 12 are all made of transparent materials, such as glass and transparent plastic. Each of the uprights 15 arranged in a circular array on the upper surface of the shell 1 is equipped with a reflector 13. The reflector 13 increases the concentration of sunlight, thereby increasing the intensity of sunlight irradiation on the cone 8 and the long cylinder. During the flow of medical wastewater, sunlight can pass through the cone 8 and the long cylinder to disinfect the medical wastewater inside with ultraviolet light, thus improving the disinfection effect.

[0039] In addition, since the reflector 13 is rotatably connected to the top of the upright 15 via the hinge block 14; the upright 15 is provided with a rack 17; and the reflector 13 is rotatably connected to the hinge block 14 at the bottom with a diagonal brace 16, and the bottom end of the diagonal brace 16 abuts against the rack 17; during use, the staff can also adjust the angle of the reflector 13 by moving the diagonal brace 16 up and down and changing the position of the bottom end abutting against the rack 17, so that a better disinfection effect can be achieved by adjusting it only once in different seasons.

[0040] Furthermore, the medical wastewater flows into the treatment chamber 2 of the shell 1 through the long pipe 11. Since the uppermost treatment chamber 2 is equipped with a guide plate 21, and the upper part of the guide plate 21 is located directly below the long pipe 11, and the lower part of the guide plate 21 is located above the L-shaped plate 19 fixed to the end of the uppermost bio-module bed 20, the medical wastewater flows to the L-shaped plate 19 under the action of the guide plate 21, flows to the bio-module bed 20 through the L-shaped plate 19, and flows to the side of the through channel 22.

[0041] During this process, the medical wastewater fully reacts with the aerobic bacteria, anaerobic bacteria, functional enzymes, and complex microbial communities loaded on the bio-module bed 20. Aerobic bacteria decompose organic pollutants in the wastewater under aerobic conditions, while anaerobic bacteria treat complex pollutants such as nitrogen and sulfur. Functional enzymes accelerate the degradation of specific organic compounds, such as oils and proteins. Through synergistic effects, the complex microbial community further enhances the degradation efficiency of various pollutants in the wastewater, ultimately achieving effective removal and transformation of harmful substances in the medical wastewater.

[0042] Finally, the treated medical wastewater flows into the bottom treatment chamber 2 of the housing 1 and flows out through the outlet pipe 18 connected to the side wall of the treatment chamber 2.
