[0117] The scraper 24 is located in the filtering space and above the filter plate 22 , and one side of the scraper 24 is in contact with the filter plate 22 . The scraper 24 is connected to the power output end of the rotating motor 23 .

[0118] The filter part 25 is located in the filter space and is arranged on the liquid inlet pipe 21. The filter part 25 is arranged below the filter plate 22. The filter part 25 has a particle filter space, and the particle filter space is connected to the filter space. The filter part 25 is used to filter the second type of solids in the waste liquid for medical examination. The particle diameter of the second type of solids is smaller than the particle diameter of the first type of solids.

[0119] The ion detection device 26 is located in the filter space and below the filter portion 25 , and is disposed on the liquid inlet pipe 21 , and is used to detect the heavy metal ion content in the medical test waste liquid. The ion detection device 26 is communicatively connected to the reagent adding device 60 .

[0120] It can be understood that the liquid inlet pipe 21 is an irregular tubular structure that allows the waste liquid for medical examination to flow into the distillation device 40. For example, the material of the liquid inlet pipe 21 can be plastic or aluminum alloy, etc., but is not limited thereto.

[0121] The filter plate 22 is a plate-like mesh structure that can be arranged in the liquid inlet pipe 21 and can separate the first type of solids (cotton swab heads, body tissues, etc.) from the liquid of the waste liquid for medical examination, and the size of the filter plate 22 can at least cover a cross-section of the liquid inlet pipe 21. For example, the filter plate 22 can be a multi-layer filter mesh, a multi-layer screen mesh, etc., but is not limited to this.

[0122] The rotating motor 23 is a device that can be arranged outside the liquid inlet pipe 21, but the power output shaft of the rotating motor 23 is located inside the liquid inlet pipe 21, and can drive the object connected to the power output shaft to rotate through the power output shaft. For example, the rotating motor 23 can be a DC micro motor, an AC micro motor, etc., but is not limited thereto.

[0123] The scraper 24 is a plate-like structure that can be located in the filtering space and is disposed above the filter plate 22 (the side of the filter plate 22 that first contacts the medical test waste liquid). The scraper 24 is connected to the power output shaft of the rotating motor 23, and one side of the scraper 24 contacts the side of the filter plate 22 that first contacts the medical test waste liquid. For example, the material of the scraper 24 can be aluminum alloy or plastic, etc., but is not limited thereto.

[0124] The filter unit 25 is a device that can be located in the filter space and below the filter plate 22 and can filter the second type of solids (macromolecular particles, blood coagulation, etc.) in the waste liquid for medical examination. For example, the filter unit 25 can be a membrane filter device 20, a sand filter device, etc., but is not limited thereto.

[0125] The ion detection device 26 is a device that can be located below the filter 25 and can detect the content of metal ions in the medical test waste liquid. For example, the ion detection device 26 can be a fluorescence spectrometer, a water quality heavy metal ion rapid determination instrument, etc., but is not limited thereto.

[0126] With such arrangement, when the waste liquid for medical examination flows in through the liquid inlet pipe 21, it first passes through the filter plate 22, which can separate the first type of solids from the waste liquid. The rotary motor 23 drives the scraper 24 to rotate, and the first type of solids attached to the filter plate 22 are swept into the solid treatment device 30, so as to avoid the first type of solids clogging the filter plate 22. Then, the waste liquid filtered by the filter plate 22 passes through the filter part 25 to remove the second type of solids in the waste liquid, so as to avoid the second type of solids affecting the treatment effect of the waste liquid for medical examination. Finally, the waste liquid flows through the ion detection device 26 and enters the distillation device 40. The ion detection device 26 determines the content of metal ions in the waste liquid and selects a suitable and appropriate amount of additives, so as to avoid the incorrect or excessive use of additives affecting the treatment effect of the waste liquid for medical examination.

[0127] In some embodiments, see Figure 3 The solid processing device 30 includes an incineration chamber 31 , a material feeding part 32 and a smoke exhaust part 33 .

[0128] The incineration chamber 31 is located in the accommodating space and is arranged on the outer shell 10. The incineration chamber 31 has a solid processing space. The incineration chamber 31 is used to incinerate the first type of solid filtered out of the waste liquid for medical examination.

[0129] The feed part 32 is located in the accommodating space and is arranged on the incineration chamber 31. One end of the feed part 32 is connected to the liquid inlet pipe 21 and is located on a side close to the scraper 24. The feed part 32 has a feed channel, and the filtering space is connected to the solid processing space through the feed channel.

[0130] The smoke exhaust part 33 is partially located in the accommodating space and is arranged on the incineration chamber 31 and corresponds to the position of the hole of the smoke exhaust shell 10. The smoke exhaust part 33 has a smoke exhaust channel, which is connected to the solid processing space.

[0131] It can be understood that the incineration chamber 31 is a device that can incinerate the solid separated by the filter device 20 and discharge the waste residue generated after incineration from the medical test waste liquid treatment device 100. For example, the incineration chamber 31 may include an incineration shell 311, a push plate 313, etc., but is not limited thereto.

[0132] The feed part 32 is a device capable of conveying the solid separated by the filtering device 20 to the incineration chamber 31. For example, the feed part 32 may include a feed pipe 321, a closing part 323, etc., but is not limited thereto.

[0133] The smoke exhaust part 33 is a device that can discharge the waste gas generated by the incineration chamber 31 after purification. For example, the smoke exhaust part 33 may include a smoke exhaust pipe 331, a waste gas treatment part 332, etc., but is not limited thereto.

[0134] With such arrangement, the solid separated by the filter device 20 is transported to the incineration chamber 31 through the feed section 32, and then the solid separated by the filter device 20 is incinerated in the incineration chamber 31 to remove the moisture in the solid and then discharged, thereby avoiding the separated solid containing a large amount of moisture, which is not conducive to transportation and may also cause secondary pollution. The waste gas generated by the incineration of the solid in the incineration chamber 31 is then purified and discharged through the smoke exhaust section 33, thereby avoiding excessive pressure in the incineration chamber 31 and air pollution.

[0135] In some embodiments, see Figure 3 The incineration chamber 31 includes an incineration shell 311 , a driving cylinder 312 , a push plate 313 , a baffle 314 , and a spring 315 .

[0136] The incineration shell 311 is located in the accommodating space and is arranged on the outer shell 10. The incineration shell 311 has a solid processing space. The incineration shell 311 is provided with a material inlet hole, a smoke exhaust hole and a slag discharge hole.

[0137] The heating wire 316 is located in the accommodation space and is arranged on the incineration shell 311 for providing heat.

[0138] The driving cylinder 312 is located in the accommodating space and is disposed on the outer shell 10 , and the power output end of the driving cylinder 312 extends into the solid processing space.

[0139] The push plate 313 is located in the solid processing space and is connected to the power output end of the driving cylinder 312 .

[0140] The baffle 314 is located in the solid processing space and is rotatably disposed on the incineration shell 311. The baffle 314 corresponds to the position of the slag discharge hole.

[0141] The spring 315 is located in the solid processing space, and two ends of the spring 315 are respectively connected to the baffle 314 and the incineration shell 311.

[0142] It can be understood that the incineration shell 311 refers to the shell or casing of the incineration chamber 31, which is the outer protective layer of the incineration chamber 31 and provides an incineration space for the incineration chamber 31. For example, the incineration shell 311 can be made of high-temperature ceramic material or aluminum alloy, but is not limited thereto.

[0143] The driving cylinder 312 is a device that can be arranged on the incineration shell 311, and the power output end of the driving cylinder 312 passes through the incineration shell 311 and is located in the solid processing space, and can drive an object connected to the power output end away from or close to the driving cylinder 312. For example, the driving cylinder 312 can be a slide cylinder, a pen-shaped cylinder, etc., but is not limited thereto.

[0144] The heating wire 316 is a wire-shaped element that can convert electrical energy into thermal energy. For example, the heating wire 316 can be a nickel-chromium alloy heating wire 316, an iron-chromium-aluminum alloy heating wire 316, etc., but is not limited thereto.

[0145] The push plate 313 is an L-shaped structure, wherein one right angle side is connected to the power output end of the driving cylinder 312. For example, the material of the push plate 313 can be made of high temperature ceramic material or aluminum alloy, but is not limited thereto.

[0146] The baffle 314 is a plate-like structure, which can be arranged on one side of the incineration shell 311 where the slag discharge hole is opened, and the size of the baffle 314 can completely close the slag discharge hole. For example, the material of the baffle 314 can be made of high-temperature ceramic material or aluminum alloy, but is not limited thereto.

[0147] The spring 315 is a component that can exert elastic force to enable the baffle 314 to return to a position where it can completely close the slag discharge hole after being pushed and rotated by the push plate 313. For example, the spring 315 can be a coil spring 315, a volute spring 315, etc., but is not limited to this.

[0148] With such arrangement, the solid separated by the filtering device 20 falls into the incineration shell 311, and the water content of the solid is removed by heating the electric heating wire 316 to make the solid burn. When the combustion is completed, the cylinder 312 is driven to drive the push plate 313 and drive the waste slag produced by the combustion to move toward the slag outlet. After the push plate 313 comes into contact with the baffle 314, it pushes the baffle 314 to rotate upward to expose the slag outlet and compress the spring 315. After the push plate 313 pushes the waste slag out of the slag outlet, the driving motor 55 drives the push plate 313 to reset. The baffle 314 is reset under the elastic action of the spring 315 and completely closes the slag outlet.

[0149] In some embodiments, see Figure 3 The feeding part 32 includes a feeding pipe 321 , a motion sensor 322 and a closing part 323 .

[0150] The feed pipe 321 is located in the accommodating space and is arranged on the incineration shell 311 and corresponds to the position of the feed hole. The feed pipe 321 has a feed channel. One end of the feed pipe 321 is connected to the incineration shell 311, and the other end of the feed pipe 321 is connected to the liquid inlet pipe 21 and is located on a side close to the scraper 24.

[0151] The motion sensor 322 is located in the feeding channel and is arranged on the feeding pipe 321 .

[0152] The closing portion 323 is partially located in the feed channel and is disposed on the feed pipe 321 and is in communication connection with the motion sensor 322 , and is located below the motion sensor 322 , and is used to cut off or open the feed channel.

[0153] It can be understood that the feed pipe 321 is a tubular structure that allows the solid filtered by the filter device 20 to fall into the combustion chamber, and one end of the feed pipe 321 can be arranged on the liquid inlet pipe 21 on one side of the scraper 24. For example, the material of the feed pipe 321 can be aluminum alloy or plastic, etc., but is not limited thereto.

[0154] The motion sensor 322 is a device that can detect whether there is solid falling in the feeding pipe 321. For example, the motion sensor 322 can be an accelerometer, an infrared detector, etc., but is not limited thereto.

[0155] The closing part 323 is a device that can be disposed below the motion sensor 322 and can cut off or open the feed pipe 321. For example, the closing part 323 can include a closing part housing 3231, a stopper 3232, etc., but is not limited thereto.

[0156] With such arrangement, when the filtering device 20 conveys filtered solids into the feed pipe 321, when the motion sensor 322 detects that solids have fallen into the feed pipe 321, an instruction is sent to the closing portion 323 to make the closing portion 323 open the feed pipe 321 so that the solids can smoothly enter the incineration chamber 31; when the motion sensor 322 does not detect that solids have fallen into the feed pipe 321, the closing portion 323 cuts off the feed pipe 321, so that the exhaust gas generated by the incineration cannot enter the outer casing 10 through the feed pipe 321, thereby avoiding damage or contamination of the internal devices.

[0157] Optionally, see Figure 4 The closing part 323 includes a closing part housing 3231, a limiter 3232, a closing motor 3233, a rotating gear 3234, two racks 3235 and two closing blocks 3236.

[0158] The closing portion shell 3231 is partially located in the feed channel and is arranged on the feed pipe 321. The closing portion shell 3231 has a closed space. The closing portion shell 3231 is provided with two drop holes that enable the first type of solid to pass through the closed space along the direction of gravity and fall into the solid processing space.

[0159] The limiting member 3232 is located in the closed space and is disposed on the closing portion housing 3231 .

[0160] The closing motor 3233 is partially located in the closed space and is arranged on the closing portion housing 3231 . The closing motor 3233 is communicatively connected with the motion sensor 322 .

[0161] The rotating gear 3234 is located in the closed space and is arranged on the power output shaft of the closing motor 3233 , and the axis of the rotating gear 3234 is colinear with the axis of the power output shaft of the closing motor 3233 .

[0162] The two racks 3235 are movably disposed in the closed space and are disposed in a direction consistent with the extension direction of the limiting member 3232 . The two racks 3235 are respectively engaged with the rotating gear 3234 and are respectively located at the upper and lower sides of the rotating gear 3234 .

[0163] The two closing blocks 3236 are located in the closed space and are respectively arranged on the two racks 3235. The two closing blocks 3236 are provided with limiting grooves matching with the limiting member 3232 on the side away from the rack 3235. The two closing blocks 3236 can be brought together or separated along the extension direction of the limiting member 3232.

[0164] It can be understood that the closing portion housing 3231 refers to the shell or casing of the closing portion 323, which is an outer protective layer of the closing portion 323. For example, the closing portion housing 3231 can be made of high temperature ceramic material or aluminum alloy, but is not limited thereto.

[0165] The stopper 3232 is a strip-shaped protruding structure, which can be disposed on the inner side of the closing portion housing 3231. For example, the material of the stopper 3232 can be a high-temperature ceramic material or an aluminum alloy, etc., but is not limited thereto.

[0166] The closing motor 3233 is a device that can be arranged on the closing portion housing 3231, but the power output shaft of the closing motor 3233 is located inside the closing portion housing 3231, and can drive the object connected to the power output shaft to rotate through the power output shaft. For example, the closing motor 3233 can be a DC micro motor, an AC micro motor, etc., but is not limited thereto.

[0167] The rotating gear 3234 is a gear structure that can rotate synchronously with the power output shaft of the closing motor 3233, and can be arranged at one end of the power output shaft of the closing motor 3233. The gear surface of the rotating gear 3234 is parallel to the closing portion housing 3231 between the rotating gear 3234 and the closing motor 3233. For example, the rotating gear 3234 can be a cylindrical gear, a micro gear, etc., but is not limited thereto.

[0168] The rack 3235 is a special gear structure with teeth distributed on a bar-shaped body that meshes with the rotating gear 3234 and can move along the extension direction of the stopper 3232 as the rotating gear 3234 rotates. The two racks 3235 can move away from or closer to each other as the rotating gear 3234 rotates. For example, the rack 3235 can be a miniature rack 3235 or a non-standard customized rack 3235, but is not limited thereto.

[0169] The closing block 3236 is a block structure, and there is an inclined surface that can fit each other between the two closing blocks 3236. The two closing blocks 3236 can follow the connected rack 3235 to move closer to make the inclined surfaces on the closing blocks 3236 fit closely or move away. The closing block 3236 is provided with a groove corresponding to the limiter 3232, and the limiter 3232 can be partially located in the groove to limit the movement direction of the closing block 3236. For example, the material of the closing block 3236 can be a high-temperature ceramic material or an aluminum alloy, etc., but is not limited thereto.

[0170] With such arrangement, when no solid passes through the feed pipe 321, the inclined surfaces between the two closing blocks 3236 are tightly fitted to close the feed pipe 321, preventing the exhaust gas generated by incineration from entering the housing 10 and damaging the equipment. When solid passes through the feed pipe 321, the closing motor 3233 drives the rotating gear 3234 to rotate counterclockwise, so that the two racks 3235 meshing with the rotating gear 3234 move away from each other along the extension direction of the limiter 3232, thereby driving the two closing blocks 3236 respectively connected to the two racks 3235 to move along the extension direction of the limiter. The extension directions of 3232 are away from each other, so that the solid can enter the incineration chamber 31 through the closing part shell 3231, and then the closing motor 3233 drives the rotating gear 3234 to rotate clockwise, so that the two racks 3235 meshing with the rotating gear 3234 are close to each other along the extension direction of the limit member 3232, thereby driving the two closing blocks 3236 respectively connected to the two racks 3235 to approach each other along the extension direction of the limit member 3232 and making the inclined surfaces on the two closing blocks 3236 fit tightly, thereby closing the feed pipe 321.

[0171] In some embodiments, see Figure 3 The smoke exhaust part 33 includes a smoke exhaust pipe 331 and a waste gas treatment part 332 .

[0172] The smoke exhaust pipe 331 is partially located in the accommodating space and is arranged on the incineration shell 311. One end of the smoke exhaust pipe 331 corresponds to the smoke exhaust hole, and the other end of the smoke exhaust pipe 331 corresponds to the hole of the smoke exhaust shell 10. The smoke exhaust pipe 331 has a smoke exhaust channel, which is connected to the solid processing space.

[0173] The waste gas treatment unit 332 is located in the smoke exhaust passage and is arranged on the smoke exhaust pipe 331 , and is used to treat harmful substances in the waste gas generated by the incineration chamber 31 .

[0174] It can be understood that the smoke exhaust pipe 331 is a tubular structure that can discharge the waste gas in the incineration chamber 31. For example, the material of the feed pipe 321 can be aluminum alloy or plastic, but is not limited thereto.

[0175] The waste gas treatment unit 332 is a device that can purify harmful substances in the waste gas generated in the incineration chamber 31. For example, the waste gas treatment unit 332 can be an activated carbon adsorption device, an oxidation deodorization device, etc., but is not limited thereto.

[0176] With such arrangement, the waste gas generated in the incineration chamber 31 is transported along the smoke exhaust pipe 331 to the waste gas treatment part 332 and after the harmful substances therein are removed, it is discharged through the smoke exhaust pipe 331, thereby reducing the pressure in the incineration chamber 31 and avoiding air pollution.

[0177] In some embodiments, see Figure 5 A distillation hole is opened on the incineration shell 311, and a solvent outlet hole is opened on the outer shell 10; the distillation device 40 includes a distillation chamber 41, a first solenoid valve 42, a second solenoid valve 43, a condenser 44 and a cooling chamber 45.

[0178] The distillation bin 41 is arranged on the incineration shell 311 and corresponds to the position of the distillation hole. The distillation bin 41 is located in the solid processing space through the distillation hole. The distillation bin 41 has a distillation space. The distillation bin 41 is provided with a first liquid hole, a second liquid hole and a third liquid hole. One end of the liquid inlet pipe 21 is connected to the first liquid hole. The filtration space is connected to the distillation space through the first liquid hole, and the mixing space is connected to the distillation space through the second liquid hole.

[0179] The first solenoid valve 42 is disposed at the connection between the liquid inlet pipe 21 and the first liquid hole, and is used to connect or disconnect the filtration space with the distillation space.

[0180] The second solenoid valve 43 is disposed at the connection between the centrifugal device 50 and the second liquid through hole, and is used to connect or disconnect the mixing space with the distillation space.

[0182] The cooling chamber 45 is located in the accommodating space and is arranged on the condenser 44. The cooling chamber 45 has a cooling space. A cold water inlet and a cold water outlet are opened on the cooling chamber 45. The cold water inlet and the cold water outlet are connected to the cooling space. The cooling chamber 45 is used to liquefy the vaporized organic solvent.

[0183] It can be understood that the distillation chamber 41 is a barrel-shaped structure that can be arranged on the incineration chamber 31. The distillation chamber 41 is used to receive the waste liquid filtered by the filter device 20 and provide a place for distillation operation. For example, the material of the distillation chamber 41 can be glass fiber reinforced plastics, ceramics, etc., but is not limited thereto.

[0184] The first solenoid valve 42 is a component that can cut off or open the liquid inlet pipe 21 to control whether the waste liquid filtered by the filter device 20 can enter the distillation chamber 41. For example, the first solenoid valve 42 can be a direct-acting solenoid valve, a micro solenoid valve, etc., but is not limited thereto.

[0185] The second solenoid valve 43 is a component that can control whether the mixing space is connected to or not connected to the distillation space. For example, the first solenoid valve 42 can be a direct-acting solenoid valve, a micro solenoid valve, etc., but is not limited thereto.

[0186] The condenser 44 is a tubular structure that can guide and output the organic solvent extracted from the waste liquid in the cooling chamber 45. For example, the material of the condenser 44 can be aluminum alloy or plastic, but is not limited thereto.

[0187] The cooling chamber 45 is a tubular structure that can hold a certain amount of cold water, and can be arranged on the condenser 44 and partially wrap the condenser 44. Cold water can enter the cooling chamber 45 from the cold water inlet and flow out through the cold water outlet. For example, the cooling chamber 45 can be made of aluminum alloy or plastic, but is not limited thereto.

[0188] With such arrangement, since the distillation chamber 41 is partially located in the incineration shell 311 through the distillation hole, the incineration chamber 31 can transfer heat to the distillation chamber 41 during the incineration process, thereby increasing the temperature of the waste liquid in the distillation chamber 41 and vaporizing the organic solvent in the waste liquid. When the vaporized organic solvent passes through the cooling chamber 45 along the condenser 44, it is liquefied due to the lowering of temperature, and finally discharged and recovered through the condenser 44, thereby avoiding the problem of pollution caused by direct discharge of organic solvents.

The baffle plate 54 is used to evenly distribute the liquid and the gas and provide an attachment area so that the waste liquid and the additive can be mixed more evenly. For example, the material of the baffle plate 54 can be plastic, aluminum alloy, etc., but is not limited thereto.

[0204] The driving motor 55 is a mechanism capable of driving the centrifugal cylinder 52 to rotate, and a power output shaft of the driving motor 55 is connected to the centrifugal cylinder 52. For example, the driving motor 55 can be a DC micro motor, an AC micro motor, etc., but is not limited thereto.

[0205] The waste liquid temporary storage part 56 is a mechanism that can store waste liquid after centrifugation of the centrifuge cylinder 52 and re-input the waste liquid into the mixing cylinder 51 or discharge it. For example, the waste liquid temporary storage part 56 may include a temporary storage bucket 561, a connecting pipe 562, etc., but is not limited thereto.

[0206] The waste liquid inlet pipe 511 is a tubular structure capable of inputting the waste liquid in the distillation device 40 into the mixing cylinder 51. For example, the material of the waste liquid inlet pipe 511 can be aluminum alloy or plastic, etc., but is not limited thereto.

[0207] The additive inlet pipe 512 is a tubular structure that can input the additive in the reagent adding device 60 into the mixing barrel 51. For example, the material of the additive inlet pipe 512 can be rubber or plastic, etc., but is not limited thereto.

[0208] The waste liquid outlet pipe 57 is a tubular structure capable of conveying the waste liquid separated by the centrifugal drum 52 to the waste liquid temporary storage portion 56. For example, the material of the waste liquid outlet pipe 57 can be aluminum alloy or plastic, but is not limited thereto.

[0209] The metal ion outlet pipe 513 is a tubular structure capable of discharging the metal ion precipitate separated in the centrifugal cylinder 52 to the outside of the housing 10. For example, the material of the metal ion outlet pipe 513 can be aluminum alloy or plastic, etc., but is not limited thereto.

[0210] In this way, the waste liquid after distillation by the distillation device 40 flows into the mixing barrel 51 through the waste liquid inlet pipe 511, and after mixing with the additive flowing into the mixing barrel through the additive inlet pipe 512, flows evenly into the centrifugal barrel 52 through the mixing hole opened on the centrifugal barrel 52 and under the guidance of the baffle plate 54. The driving motor 55 drives the centrifugal barrel 52 to rotate. Under the action of centrifugal force, the metal ions with higher density in the waste liquid precipitate to the side of the barrel wall of the centrifugal barrel 52, flow out of the centrifugal barrel 52 through the heavy phase outlet hole, and are discharged through the metal ion outlet pipe 513, so as to avoid the direct discharge of metal ions in the waste liquid to cause environmental pollution; the liquid with lower density in the waste liquid moves to the side of the dividing rod 53, flows out of the centrifugal barrel 52 through the light phase outlet hole, and flows into the waste liquid temporary storage part 56 through the waste liquid outlet pipe 57.

[0211] In some embodiments, see Figure 6 The housing 10 is provided with a liquid outlet; the waste liquid temporary storage portion 56 includes a temporary storage barrel 561, a connecting pipe 562, a third solenoid valve 563, a drain pipe 564 and a fourth solenoid valve 565.

[0212] The temporary storage barrel 561 is arranged in the accommodating space. The temporary storage barrel 561 is provided with a first temporary storage hole, a second temporary storage hole and a third temporary storage hole. The first temporary storage hole is connected to the waste liquid outlet pipe 57. The temporary storage barrel 561 has a waste liquid temporary storage space, and the waste liquid temporary storage space is connected to the mixing space and the centrifugal space. The waste liquid temporary storage part 56 is used to store waste liquid for medical examination after centrifugation.

[0213] The connecting tube 562 is located in the accommodating space, one end of the connecting tube 562 is connected to the second temporary storage hole, and the other end of the connecting tube 562 is connected to the waste liquid inlet pipe 511 . The waste liquid temporary storage space is connected to the mixing space through the connecting tube 562 .

[0214] The third solenoid valve 563 is located in the accommodating space and is disposed on the connecting pipe 562, and is used to connect or disconnect the waste liquid temporary storage space with the mixing space.

[0215] The drain pipe 564 is located in the accommodation space and is disposed on the temporary storage barrel 561 . One end of the drain pipe 564 is connected to the third temporary storage hole, and the other end of the drain pipe 564 is connected to the liquid outlet hole.

[0216] The fourth solenoid valve 565 is located in the accommodating space and is disposed on the drain pipe 564 for cutting off or opening the drain pipe 564 .

[0217] It can be understood that the temporary storage barrel 561 is a barrel-shaped structure that is connected to the mixing barrel 51 and can store waste liquid. For example, the material of the temporary storage barrel 561 can be glass fiber reinforced plastics, ceramics, etc., but is not limited thereto.

[0218] The connecting pipe 562 is a tubular structure that can transport the waste liquid in the temporary storage barrel 561 to the waste liquid inlet pipe 511 and flow into the mixing barrel 51 through the waste liquid inlet pipe 511. For example, the material of the connecting pipe 562 can be aluminum alloy or plastic, etc., but is not limited thereto.

[0219] The third solenoid valve 563 is a mechanism that can cut off or open the connecting pipe 562 to allow the waste liquid in the temporary storage barrel 561 to flow into the connecting pipe 562 or not. For example, the third solenoid valve 563 can be a direct-acting solenoid valve, a micro solenoid valve, etc., but is not limited thereto.

[0220] The drain pipe 564 is a tubular structure capable of transferring waste liquid in the temporary storage barrel 561 to the outside of the housing 10. For example, the material of the drain pipe 564 can be aluminum alloy or plastic, but is not limited thereto.

[0221] The fourth solenoid valve 565 is a mechanism that can cut off or open the drain pipe 564 so that the waste liquid in the temporary storage barrel 561 can be discharged to the outside of the housing 10 through the drain pipe 564. For example, the fourth solenoid valve 565 can be a direct-acting solenoid valve, a micro solenoid valve, etc., but is not limited thereto.

[0222] With such a configuration, when the liquid with a lower density separated in the centrifugal barrel 52 flows into the temporary storage barrel 561 through the waste liquid outlet pipe 57, the third solenoid valve 563 and the fourth solenoid valve 565 are in a closed state so that the temporary storage barrel 561 can store the waste liquid. When there is no waste liquid in the mixing barrel 51, the third solenoid valve 563 is opened so that the waste liquid in the temporary storage barrel 561 flows into the waste liquid inlet pipe 511 through the connecting pipe 562 and flows into the mixing barrel 51 to mix with the additive. The waste liquid is mixed with different additives respectively through the temporary storage barrel 561 and the third solenoid valve 563 to avoid mixing multiple additives together to affect the precipitation effect of metal ions in the waste liquid. After the waste liquid is mixed with the additive to be mixed, the fourth solenoid valve 565 is switched from a closed state to an open state, so that the waste liquid in the temporary storage barrel 561 can be discharged to the outside of the housing 10 through the drain pipe 564, so as to avoid the metal ions contained in the waste liquid from damaging the environment.

[0223] In some embodiments, see Figure 7 The reagent adding device 60 includes a liquid storage barrel 61 , a dust cover 62 and a throttle valve 63 .

[0224] The liquid storage barrel 61 is arranged on the outer shell 10, and the liquid storage barrel 61 has a reagent adding space. The position of the liquid storage barrel 61 corresponds to the position of the reagent adding hole. A leakage hole is opened on one side of the liquid storage barrel 61 that penetrates into the accommodating space. One end of the additive inlet pipe 512 is connected to the leakage hole. The reagent adding space is connected to the mixing space through the additive inlet pipe 512.

[0225] The dust cover 62 is partially located in the reagent adding space and is openably disposed on the liquid storage barrel 61 for closing or opening the reagent adding space.

[0226] The throttle valve 63 is located in the accommodating space and is arranged at the connection between the liquid storage barrel 61 and the additive inlet pipe 512. The throttle valve 63 is communicated with the ion detection device 26. The throttle valve 63 is used to connect or disconnect the reagent adding space with the mixing space.

[0227] It can be understood that the liquid storage barrel 61 is a barrel-shaped structure that is connected to the mixing barrel 51 and can store additives. For example, the material of the liquid storage barrel 61 can be glass fiber reinforced plastic, plastic, etc., but is not limited thereto.

[0228] The dust cover 62 is a cover-like structure that can be opened and closed to allow the additive in the liquid storage barrel 61 to contact or not contact the air. For example, the dust cover 62 can be a plastic dust cover 62, a rubber dust cover 62, etc., but is not limited thereto.

[0229] The throttle valve 63 is a mechanism that can control the liquid in the liquid storage barrel 61 to flow into or not flow into the mixing cylinder 51. For example, the throttle valve 63 can be a direct-acting electromagnetic valve, a micro electromagnetic valve, etc., but is not limited thereto.

[0230] With such a configuration, when it is necessary to add additives to the liquid storage barrel 61, it is only necessary to open the dust cover 62 to add additives to the liquid storage barrel 61, and then the dust cover 62 is fitted to the liquid storage barrel 61 to prevent the additives in the liquid storage barrel 61 from contacting with the air and causing contamination. After the ion detection device 26 detects the content of various metal ions in the waste liquid, it controls the throttle valve 63 on the liquid storage barrel 61 containing additives corresponding to the various metal ions to be in an open state, so that the additives that can precipitate the metal ions in the waste liquid flow into the mixing barrel 51 to react with the waste liquid. After the additives corresponding to the metal ion content flow into the mixing barrel 51, the throttle valve 63 changes from an open state to a closed state, so that the additives in the liquid storage barrel 61 cannot flow into the mixing barrel 51, avoiding waste caused by excessive additives while affecting the metal ion precipitation effect.

[0231] The present application also provides a method for using a medical test waste liquid treatment device, which is applied to the medical test waste liquid treatment device 100 of any of the above embodiments, and the method includes:

[0235] The distillation device 40 receives the waste liquid for medical examination that has passed through the filtering device 20 and separates the organic solvent from the waste liquid for medical examination.
