Description

Technical Field

[0001] This invention belongs to the field of wastewater treatment technology, specifically relating to an automated medical wastewater treatment device. Background Technology

[0002] Medical wastewater, as a high-risk pollution source, requires dual purification through a combination of physical and biological processes: First, physical impurities such as cotton swabs and dressings larger than 5mm are intercepted by a mechanical screen, combined with ozone catalytic oxidation to degrade chemical pollutants such as antibiotics and contrast agents; then, biological treatment is carried out using a sequencing batch reactor (SBR), followed by deep filtration of residual drug components and pathogenic microorganisms through an ultrafiltration-reverse osmosis dual-membrane system; finally, ultraviolet light and sodium hypochlorite are used for synergistic disinfection to ensure that the water quality meets the core indicators of the "Emission Standard of Water Pollutants for Medical Institutions" (GB18466-2005), such as fecal coliforms <500MPN / L and CODcr ≤60mg / L. An online monitoring system is installed throughout the treatment process to achieve compliant discharge and ecological safety management.

[0003] The existing publication number CN216320220U proposes an environmental protection wastewater filtration device, which mainly increases the contact surface with wastewater and improves wastewater treatment efficiency by using a side-wall impact inclined grid structure. However, this type of device has a limited application scope and cannot be specifically adjusted according to medical wastewater treatment standards in the diversified treatment of medical wastewater. Moreover, the inclined design often means a larger cleaning area. If the cleaning is not thorough, it often leads to the accumulation of bacteria in the integrated wastewater treatment equipment, affecting the subsequent wastewater treatment standards. Therefore, we propose an automated medical wastewater treatment device. Summary of the Invention

A liquid level sensing structure is installed at the bottom of one side of the discharge pipe, and a liquid level hole is opened at the top position of the discharge pipe on one side, with a self-control valve plate fixedly installed on the liquid level hole.

[0008] Furthermore, a feeding structure is fixedly installed at the lowest position of the liquid level hole on the multi-purpose reaction tank. The feeding structure is fixed at the top of the mixing chamber, and multiple multi-angle stirring rollers are distributed in a ring inside the mixing chamber. The multi-angle stirring rollers are fixed on the output shaft of the servo drive motor, and the drainage pipe is fixed through and fixed at the bottom of the mixing chamber.

[0015] 1. In this solution, the sedimentation tank and the corresponding liquid level hole inside the sewage treatment tank are used to clean and screen the sedimented liquid in the multi-purpose reaction tank, which effectively realizes the step-by-step reaction of sewage with different concentrations. The multi-angle stirring rollers inside the multi-purpose reaction tank ensure that the added chemical solution reacts fully, thereby improving the sewage treatment efficiency.

[0027] Reference Figures 1-7 The present invention proposes a technical solution: a self-controlled medical wastewater treatment device, including a wastewater treatment tank 1. One end of the wastewater treatment tank 1 is provided with an inlet pipe 11 that is connected to a wastewater pretreatment tank. The interior of the wastewater treatment tank 1 is divided into an equalization tank 14 and a sedimentation tank 15. A sealing end cap 13 is fixedly installed at the top of the wastewater treatment tank 1. A return pipe 141 is opened at the bottom of the inner side of the equalization tank 14. A double-slope sieve plate 142 is installed at the top of the return pipe 141 inside the equalization tank 14. A grid plate 18 for controlling the flow rate is fixedly installed at the layer between the equalization tank 14 and the sedimentation tank 15. An angled grid plate 152 is provided inside the sedimentation tank 15. A discharge pipe 151 is opened at the bottom of the sedimentation tank 15. A multi-purpose reaction tank 16 is provided on one side of the sedimentation tank 15. A drainage pipe 167 is fixedly installed at the bottom of one side of the multi-purpose reaction tank 16. A feeding structure 17 is provided at the top of the rear end of the multi-purpose reaction tank 16.

[0028] A controllable booster pump 12 is connected to one end of the sewage treatment tank 1 corresponding to the sedimentation tank 15. The outlet of the controllable booster pump 12 is located near the hole of the discharge pipe 151. The controllable booster pump 12, which is installed on the sedimentation tank 15, enables rapid cleaning of the angled grid plate 152. At the same time, the return pipe 141 and the discharge pipe 151 installed on the equalization tank 14 and the sedimentation tank 15 increase the cleaning efficiency. Under the premise of rapid discharge of coarse screen debris, it can also effectively treat and discharge the residual sewage from the cleaning of the machine box in the reverse direction.

[0029] A filter element baffle 156 is detachably installed on the inner side of the discharge pipe 151. A liquid level sensing structure 155 is installed at the bottom of one side of the discharge pipe 151. The liquid level sensing structure 155 is mainly used to indicate the height of flocculent precipitate. When the precipitate height is higher than the preset height, the external buzzer, flashing indicator light and other structures are activated to indicate the cleaning. A liquid level hole 153 is opened at the top of the discharge pipe 151 on one side, and a self-control valve plate 154 is fixedly installed on the liquid level hole 153.

[0030] A feeding structure 162 is fixedly installed at the lowest position of the liquid level hole 153 on the multi-purpose reaction tank 16. The feeding structure 162 is fixed at the top position of the mixing chamber 163. Multiple multi-angle stirring rollers 164 are distributed in a ring inside the mixing chamber 163. The multi-angle stirring rollers 164 are fixed on the output shaft of the servo drive motor 165. The drainage pipe 167 is fixed through and fixed at the bottom position of the mixing chamber 163.

[0031] A sealed top cover 161 is fixedly installed at the top of the multi-purpose reaction tank 16, and a shock-absorbing rubber ring 166 is fitted on the outer side of the mixing chamber 163.

[0032] A feeding port 171 is provided at the top of the feeding structure 17, and a crusher 174 is distributed horizontally inside the feeding structure 17. An electrically controlled pressure boosting device 173 is fixedly installed at the top of the feeding port of the feeding structure 17. The ends of the feeding port of the feeding structure 17 are all fixedly connected to the connecting pipe 172. The connecting pipe 172 is connected to the top of the feeding structure 162 on the multi-purpose reaction tank. An offset electrically controlled valve 181 is fixedly installed on the grid plate 18.

[0033] The sealing end cap 13 is hinged to the top of the regulating tank 14 and the main chamber top cap 131 is hinged to the top of the sedimentation tank 15.

[0034] To facilitate the replacement and maintenance of the angled grid plate 152, a limiting groove is provided on the side wall of the sedimentation tank 15 for placing the angled grid plate 152. The angled grid plate 152 can be effectively and quickly disassembled by sliding it up and down.

[0035] The working principle and usage process of this invention: This type of self-controlled medical wastewater treatment equipment is mainly used for the secondary screening of pre-treated wastewater through stratification reaction. When the pre-treated wastewater connected to the inlet pipe 11 flows into the regulating tank 14, the structure on the double-slope screen plate 142 effectively blocks the sedimentation of large particles of wastewater. At the same time, a chemical solution is added for preliminary degradation, and the misaligned electric control valve is controlled. The 181-meter grid width enables secondary isolation of wastewater. When medical wastewater flows into the sedimentation tank 15, the inclined surface of the angled grid plate 152 facilitates the reflux and rotation of the medical wastewater, accelerating the sedimentation reaction. When the sediment accumulation height reaches the predetermined position of the liquid level hole 153, the self-control valve plate 154 is moved downward, allowing the middle and upper liquids to flow into the multi-purpose reaction tank 16. When it is necessary to add medicine, it can be directly filled through the feeding structure 17. It should be noted that the multi-purpose reaction tank 16 is electrically driven by the servo drive motor 165 to drive the multi-angle stirring roller 164 for full reaction. This part can be disinfected by adding ozone, ultraviolet, etc. This part can be added at the sealed top cover 161. It should also be noted that a pressurization module can be added to the drainage pipe 167 and connected to the discharge pipe 151 through a three-way pipe to ensure the normal drainage function of the discharge pipe 151 and also to achieve reflux secondary reaction.

[0036] It should be added that when a single reaction solution needs to be added to the feeding structure 17, the solution is directly added into the interior of the feeding structure 17 through the feeding port 171. The internal stirring rod of the crusher 174 is rotated to assist in fine crushing, and the solution flows to the discharge pipe section of the feeding structure 17. It is then discharged into the interior of the connecting pipe 172 through the electrically controlled pressurization device 173, and finally flows into the interior of the multi-purpose reaction tank 16, achieving rapid dosing. It should also be noted that when a single pipe is added, the other pipes should be in a closed state to avoid pressurization backflow, thus completing the use.

[0037] According to the above working process, in this solution, by using the sedimentation tank 15 and the corresponding liquid level hole 153 set inside the sewage treatment tank 1, the multi-purpose reaction tank 16 is added to clean and screen the sedimented liquid, effectively realizing the step-by-step reaction of sewage of different concentrations; by using the multi-angle stirring roller 164 set inside the multi-purpose reaction tank 16, the added chemical solution can fully react, increasing the sewage treatment efficiency.

[0038] The above are merely preferred embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
