Description

Technical Field

[0001] The invention relates to the technical field of wastewater treatment, in particular to a medical wastewater sterilization treatment device. Background Art

[0002] Medical wastewater contains various harmful substances, such as bacteria, viruses, drug residues, etc. If discharged directly into the environment, it will pollute the surrounding water and soil. Through sterilization treatment, these harmful substances can be effectively removed to protect the cleanliness and health of the surrounding environment. At the same time, preventing the spread of disease is also one of the important purposes of medical wastewater sterilization treatment. Medical wastewater may contain various pathogens. Through sterilization treatment, pathogens can be effectively killed, the risk of disease transmission can be reduced, and public health can be protected.

[0003] In the prior art, sterilization solutions for medical wastewater include ozone sterilization, ultraviolet sterilization, etc. At the same time, the treatment process for medical wastewater also includes acid-base neutralization treatment of the wastewater, thereby controlling the pH value. However, in the conventional solution, in order to ensure that the neutralization solution can be fully mixed with the wastewater, stirring treatment is required. The stirring process will cause the entire water body to shake to a large extent, which is likely to cause the sediment at the bottom to be partially lifted up again, and the shaking will also cause the top and bottom solutions to exchange, making it impossible for the sterilization and disinfection area solution generated by the ultraviolet light provided at a fixed position to remain stable, and it is difficult to ensure that the sterilization and disinfection effects of the wastewater injected at different times remain consistent, and thus it is easy to have dead corners for sterilization and disinfection.

DETAILED DESCRIPTION

[0027] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0028] See also Figures 1 to 7 The present invention provides the following technical solutions: a medical wastewater sterilization treatment device, comprising a sterilization treatment device body, the sterilization treatment device body comprising a disinfection tank 1 and a neutralization tank 2, the interior of the disinfection tank 1 is filled with an ultraviolet disinfection component 12, a panel 33 is welded on the inner wall of the disinfection tank 1, the side of the ultraviolet disinfection component 12 is in contact with the inner wall of the disinfection tank 1, a support plate 5 is welded on the side of the neutralization tank 2, a neutralization solution tank 6 and a pressure pump 7 are placed on the top of the support plate 5, and the pressure pump 7 is connected to the interior of the neutralization solution tank 6 through a pipeline, a delivery pipeline 8 is inserted at the front end of the pressure pump 7, and the end of the delivery pipeline 8 is embedded in the interior of the neutralization tank 2, a mixing cavity 10 is integrally formed at the inner bottom of the neutralization tank 2, a quantitative stirring component 9 is inserted on the inner wall of the neutralization tank 2, and a push plate 28 is welded at the bottom of the quantitative stirring component 9, the push plate 28 is integrally embedded in the interior of the mixing cavity 10, and a positioning component 11 is welded at one end of the mixing cavity 10. The medical wastewater sterilization treatment device is used for sterilizing, disinfecting, neutralizing and precipitating collected medical wastewater.

[0029] When the present invention is used, the collected medical wastewater is directly injected into the interior of the device from the injection port 3, and the top layer area of ​​the injected wastewater is irradiated and sterilized by the ultraviolet disinfection component 12 on the top. As for the bottom layer area of ​​the wastewater, by starting the quantitative stirring component 9, the push plate 28 at the bottom is swung back and forth inside the mixing cavity 10, so that part of the wastewater at the bottom can be pumped into the interior of the mixing cavity 10 during the swinging process, and the external pressure pump 7 is started synchronously to pump out the neutralization solution and inject it into the bottom of the neutralization tank 2 along the conveying pipe 8, and finally synchronously pumped into the interior of the mixing cavity 10 for uniform mixing, and finally discharged from the discharge pipe 4 at one end as the quantitative stirring component 9 swings.

[0030] In this embodiment, an arc groove 14 is provided in the middle of the surface of the mixing cavity 10, and end plates 15 are integrally formed at both ends of the mixing cavity 10. The quantitative stirring assembly 9 includes a driving shaft 25, an arc sealing plate 27 and a push plate 28. The side of the neutralization tank 2 is screwed with a motor 24, and the driving shaft 25 is inserted into the output end of the motor 24. A transmission frame 26 is welded on the surface of the driving shaft 25, and an arc sealing plate 27 is integrally formed at the end of the transmission frame 26. The push plate 28 is welded to the middle position of the bottom of the arc sealing plate 27. The arc sealing plate 27 is integrally embedded in the interior of the arc groove 14, and the width of the arc sealing plate 27 is the same as the width of the arc groove 14. The push plate 28 is embedded with a magnetic sheet 32, and a plug rod 30 is embedded in the middle of the magnetic sheet 32. A bonding plate 29 is integrally formed at one end of the outer side of the plug rod 30. A through hole 31 is opened on the surface of the push plate 28. The bonding plate 29 is pressed on the surface of the through hole 31 after being adsorbed by the magnetic sheet 32. A discharge pipe 4 is inserted at one end of the mixing cavity 10, and a first one-way valve 13 is installed on the surface of the discharge pipe 4. The first one-way valve 13 is used to discharge the solution inside the mixing cavity 10 toward the outside. The end of the drive shaft 25 is embedded in the inner wall of the neutralization tank 2 through a bearing. A mixing cavity 10 is provided at the bottom of the neutralization tank 2, which can be used in conjunction with the quantitative stirring component 9 to stir the wastewater injected with the neutralization solution. The entire stirring process is limited to the interior of the mixing cavity 10, and will not interfere with the precipitated part generated outside. At the same time, it will not cause the wastewater undergoing stratified disinfection at the top to be stirred. At the same time, the processes of sterilization, precipitation and neutralization are realized, and are independent of each other and will not affect each other.

[0031] Specifically, after the motor 24 is started, the motor 24 drives the driving shaft 25 to rotate, the driving shaft 25 drives the transmission frame 26 on the surface to rotate, the transmission frame 26 and the arc-shaped sealing plate 27 at the edge drive the push plate 28 at the bottom to rotate, because the push plate 28 is always inside the mixing cavity 10 and reciprocates along the inner arc path of the mixing cavity 10, when the push plate 28 is moved toward the discharge pipe 4 by the operation of the motor 24, as shown in FIG. Figure 2 and Figure 5As shown, the push plate 28 discharges the wastewater on the right side directly from the discharge pipe 4 at the right end. During this process, the wastewater on the right side will be squeezed, and the bonding plate 29 will be partially adsorbed by the magnetic sheet 32, resulting in the covering and sealing of each through hole 31. Therefore, the wastewater on the right side cannot flow from the through hole 31 to the left side. At the same time, the wastewater at the bottom of the neutralization tank 2 will be drawn from the extraction port 21 into the interior of the connecting lifting sleeve 18, and pass through the second one-way valve 17 and the extraction pipe 16 to enter the left side of the push plate 28. When the push plate 28 moves toward the left side as the motor 24 flips, the wastewater on the left side will be compressed, and this part of the wastewater cannot pass through the second one-way valve 17, and can only pass through the channel to lift the bonding plate 29 on the right side of the push plate 28, so that the wastewater inside the mixing cavity 10 can only flow into the left side of the push plate 28 through the through hole 31, and then repeat the above process to complete the reciprocating swing to achieve the process of mixing, pumping and discharging.

[0032] In this embodiment, the positioning assembly 11 includes a connecting lifting sleeve 18 and a closed lifting sleeve 19. The other end of the mixing cavity 10 is plugged with an extraction pipe 16. The surface of the extraction pipe 16 is installed with a second one-way valve 17. The end of the extraction pipe 16 is inserted into the interior of the connecting lifting sleeve 18. The top of the connecting lifting sleeve 18 is provided with an extraction port 21. The surface of the closed lifting sleeve 19 is welded with a pressure plate 22. The top of the pressure plate 22 is welded with a linkage bracket 20. The top of the linkage bracket 20 is welded to the top area of ​​the connecting lifting sleeve 18 as a whole. The top of the closed lifting sleeve 19 is in a sealed state. The second one-way valve 17 is used to introduce the solution inside the connecting lifting sleeve 18 into the interior of the mixing cavity 10. The bottom of the closed lifting sleeve 19 is plugged with a connecting pipe 23. The other end of the connecting pipe 23 is inserted into the interior of the mixing cavity 10. The interior of the mixing cavity 10 is always connected with the interior of the closed lifting sleeve 19. A positioning component 11 is installed at one end of the mixing cavity 10. Since the purpose of fully mixing the wastewater and the neutralization solution inside the mixing cavity 10 is achieved through the quantitative stirring component 9, the quantitative stirring component 9 can periodically draw in external wastewater during the periodic reciprocating rotation. In conjunction with the linkage bracket 20 in the positioning component 11, the extraction port 21 can be lifted each time the wastewater is discharged, and in conjunction with the pressure plate 22, it can be ensured that the extraction port 21 can be above the sedimentation layer to avoid drawing in the sediment, so that the wastewater finally discharged will not be mixed with sediment.

[0033] Specifically, when the push plate 28 swings toward the left, the obstruction of the second one-way valve 17 prevents the waste water from passing through the extraction pipe 16, and therefore can only pass through the connecting pipe 23 into the interior of the closed lifting sleeve 19, and finally lifts the linkage bracket 20 on the top of the closed lifting sleeve 19, and synchronously drives the right extraction port 21 to rise. When the push plate 28 swings toward the right end, and discharges the waste water inside the mixing cavity 10, and at the same time draws in the waste water at the bottom of the neutralization tank 2, at this time, due to the pressure reduction on the left side of the push plate 28, the closed lifting sleeve 19 is no longer lifted, which can drive the linkage bracket 20 and the pressure plate 22 to fall, and finally press on the sediment on the bottom layer through the pressure plate 22, so that the extraction port 21 part can always be at a fixed height at the top of the sediment to extract the waste water, so as to avoid the sediment being synchronously drawn into the interior of the mixing cavity 10 for discharge.

[0034] In this embodiment, the ultraviolet disinfection assembly 12 includes a surrounding plate 33 and a top plate 35, a first diversion hole 34 is provided at the bottom of the surrounding plate 33, a UV lamp 36 is embedded at the bottom of the top plate 35, a side baffle 37 is integrally formed at the bottom of the side edge of the top plate 35, a floating plate 39 is fixed at the bottom of the side baffle 37, and a second diversion hole 38 is provided at the bottom of the side baffle 37. The bottom of the first diversion hole 34 is aligned with the surface of the floating plate 39, the side of the floating plate 39 is in contact with the inner wall of the disinfection tank 1, and the bottom of the injection port 3 is aligned with the top of the surrounding plate 33. The purpose of disinfection is achieved by irradiating downward from the top area of ​​the wastewater solution through the ultraviolet disinfection component 12 at the top, and with the help of the two-layer diversion structure, the injected wastewater is ensured to be evenly dispersed in the top area, and the neutralized wastewater is periodically discharged with the help of the bottom. Combined with the continuous replenishment of wastewater from the top layer, the wastewater inside the entire tank can be continuously stratified while maintaining stability, ensuring that the injected wastewater can flow downward stably, so that the disinfection effect at any time and any position remains balanced and uniform, and will not be disturbed by the stirring and neutralization process at the bottom.

[0035] Specifically, after the wastewater is injected from the injection port 3 at the top, it will first fall into the inner side of the enclosure 33, flow along the enclosure 33, and simultaneously flow downward from the multiple first diversion holes 34 at the bottom, fall into the outer side of the side baffle 37 and the top of the floating plate 39, and finally enter the bottom of the top plate 35 from the second diversion hole 38 on the side baffle 37. This process can ensure that the wastewater is injected along the injection port 3 at a fixed point and enter the bottom of the ultraviolet lamp 36 evenly from the surrounding area. With the discharge of the bottom wastewater and the injection of the top wastewater, the wastewater is continuously stratified, and the wastewater injected at any time can be directly irradiated by ultraviolet rays for the same period of time.
