Description

Technical Field

[0001] The present invention relates to the technical field of waste liquid treatment, and more particularly, to a waste liquid treatment device for medical examination. Background Art

[0002] Medical examination is the examination of materials taken from the human body in aspects such as microbiology, immunology, biochemistry, genetics, hematology, biophysics, cytology, etc. Medical examination mainly relies on various detection reagents and various detection instruments. Therefore, a large amount of waste liquid will be generated after the detection.

[0003] The components in medical examination waste liquid are relatively complex and may contain a large amount of toxic and harmful substances, overly acidic or alkaline substances, bacteria, viruses, etc. Therefore, it needs to be specially treated before discharge. However, hospitals, laboratories and other places do not have the conditions to treat such waste. Therefore, it is usually necessary to transfer it to a special treatment plant and use special treatment equipment for treatment. Therefore, it is necessary to transfer the waste liquid into a special container, transport it to the treatment plant and then transfer it to the relevant treatment equipment for treatment. Therefore, there are many steps of liquid transfer in this process, and there is a high risk of liquid and gas leakage during the transfer of the waste liquid. Moreover, multiple transfer operations are also very troublesome and pose certain risks to the operator. Therefore, a more efficient waste liquid treatment device can be designed. Summary of the Invention

[0004] The purpose of the present invention is to provide a waste liquid treatment device for medical examination, which can efficiently transfer and treat medical examination waste liquid and reduce intermediate transfer steps.

[0014] The technical solution of the present invention has at least the following advantages and beneficial effects: For the waste liquid treatment device for medical inspection of the present invention, when in use, place the waste liquid barrel containing waste liquid on the bottom plate, then connect the air inlet pipe to the air supply device, connect the liquid inlet pipe to the liquid supply device, connect the exhaust pipe to the waste gas treatment device, and then the liquid supply device pumps reagents such as disinfectant, pH neutralizing liquid, and flocculant into the waste liquid barrel to react with the waste liquid.

Specifically, for the waste liquid treatment device for medical inspection in this embodiment, when in use, the waste liquid bucket 21 filled with waste liquid is placed on the bottom plate 11, then the air inlet pipe 25 is connected to the gas supply device 40, the liquid inlet pipe 24 is connected to the liquid supply device 50, and the exhaust pipe 23 is connected to the exhaust gas treatment device 60. Then the liquid supply device 50 pumps reagents such as disinfectant and pH neutralizing liquid into the waste liquid bucket 21 to react with the waste liquid. The gas supply device 40 injects high-pressure air into the waste liquid in the waste liquid bucket 21, which plays a role in churning and stirring the waste liquid, and discharges the toxic and harmful gases generated during the reaction through the exhaust pipe 23 into the exhaust gas treatment device 60 for treatment and then discharge. The treated waste liquid can be directly discharged through the liquid discharge pipe 26 or discharged into other equipment for subsequent treatment. The waste liquid bucket 21 can directly serve as the first container for waste liquid collection, without the need to transfer the waste liquid multiple times. That is to say, the waste liquid generated during the medical detection process can be directly discharged (through the liquid inlet pipe 24) into the waste liquid bucket 21 (classification is required), and then the waste liquid bucket 21 is sealed with the sealing cover 22. After sealing, it can be directly transferred to the bottom plate 11 for treatment. The whole process does not require complex waste liquid transfer, sealing and other operations, which can effectively improve the transfer and treatment efficiency of waste liquid, reduce the risk of waste liquid and exhaust gas leakage, reduce the number of transfer equipment, and reduce the cost of waste liquid treatment.

[0022] In this embodiment, a filter frame 27 is slidably arranged in the waste liquid bucket 21, and a plurality of filter holes 212 are formed in the bottom wall of the filter frame 27; the outer wall of the filter frame 27 is slidably connected to the inner wall of the waste liquid bucket 21; the air inlet pipe 25 and the liquid discharge pipe 26 are both arranged below the filter frame 27. A vertical screw rod 29 is arranged in the box body 12, a sleeve 28 is fixedly arranged in the middle of the filter frame 27, and a support pipe 210 is fixedly arranged at the bottom of the waste liquid bucket 21; the projection of the waste liquid bucket 21 on the horizontal plane is square; the lower end of the screw rod 29 is rotatably arranged in the support pipe 210, the upper end of the screw rod 29 is rotatably connected to the sealing cover 22, and the sleeve 28 is threadedly connected to the screw rod 29. Specifically, a flocculant is added to the waste liquid bucket 21 through the liquid supply device 50, and air is sent into the waste liquid bucket 21 through the air supply device 40 to stir the waste liquid, so that the flocculant is fully dispersed in the waste liquid, and then the waste liquid is allowed to stand for flocculation. After the flocculation is completed, the screw rod 29 is driven to rotate, so that the sleeve 28 rises along the screw rod 29. During the rising process of the sleeve 28, the filter frame 27 is driven to rise, and the solid impurities flocculated in the waste liquid are collected in the filter frame 27. Finally, the filter frame 27 moves to the upper end of the waste liquid bucket 21. After the sealing cover 22 is opened, it can be taken out and collected for treatment. In this way, the content of solid impurities and toxic and harmful substances in the discharged waste liquid can be reduced. And during the process of adding the flocculant, the filter frame 27 is at the lower end of the waste liquid bucket 21. Therefore, the air entering the waste liquid bucket 21 from the air inlet pipe 25 will enter the waste liquid bucket 21 after passing through the filter holes 212 on the filter frame 27. In this way, the gas is fully dispersed, and the waste liquid can be stirred better.

[0023] In this embodiment, a driving device 30 for driving the screw rod 29 to rotate is further included.

Specifically, when it is necessary to drive the screw rod 29 to rotate, the driving rod 33 can be pulled down to insert it into the driving groove 211, and then the motor 31 is started, and the screw rod 29 can be driven to rotate slowly through the driving rod 33, so that the filter frame 27 moves up slowly.

[0027] A weighing device 13 is arranged on the bottom plate 11 in this embodiment, and the waste liquid bucket 21 is placed on the weighing device 13. Specifically, before treating the waste liquid, the weight of the waste liquid can be weighed first, and then the components and contents in the waste liquid are detected, which is convenient for accurately using reagents such as disinfectant.

[0028] In summary, for the waste liquid treatment device of medical inspection in this embodiment, when in use, the waste liquid bucket 21 filled with waste liquid is placed on the bottom plate 11, then the air inlet pipe 25 is connected to the air supply device 40, the liquid inlet pipe 24 is connected to the liquid supply device 50, and the exhaust pipe 23 is connected to the waste gas treatment device 60.
