Description

Technical Field

[0001] This invention relates to the field of waste liquid treatment technology, specifically to a waste liquid treatment device for medical testing. Background Technology

[0002] Medical laboratory waste liquids mainly contain various hazardous components, including chemical, biological, and radioactive substances, and must be collected separately and treated professionally before being discharged. These waste liquids are commonly found in blood analysis, biochemical testing, and immunoassay processes, and originate from used reagents, specimen residues (such as blood and urine), and waste liquids generated from cleaning equipment. When treating medical laboratory waste liquids, appropriate reagents need to be added for neutralization.

[0003] Waste liquid treatment equipment is an environmentally friendly device used to treat hazardous waste liquids generated in industries, laboratories, medical fields, etc. It can separate, degrade or transform pollutants in waste liquids through physical, chemical or biological methods, so that they meet emission standards or achieve resource recycling.

[0004] Existing wastewater treatment equipment treats (neutralizes) wastewater by adding chemicals. However, this process typically involves single-point chemical feeding, which can create mixing dead zones, resulting in insufficient contact between the chemicals and the wastewater and low reaction efficiency. Furthermore, the lack of a wastewater recycling mechanism makes it difficult to maintain a stable concentration gradient within the reaction system. This is particularly problematic for wastewater requiring precise reaction control, leading to significant fluctuations in treatment effectiveness and potential waste due to localized over-dosing or incomplete reactions. Summary of the Invention

[0005] The purpose of this invention is to provide a medical testing waste liquid treatment device to solve the problems mentioned in the background art.

A stirring inner liner is installed on the outer side of the top of the cross-shaped base. An upper annular baffle is installed on the top of the stirring inner liner via screws, and the upper annular baffle is installed inside the waste liquid treatment tank. The outer side of the stirring liner and the inner side of the waste liquid treatment tank form an annular circulation channel.

[0009] As a preferred embodiment of the present invention, a circulating dosing device is installed on one side of the inner side of the stirring tank, and multiple flow ports are provided at the eccentric part of the interior of the cross base. A rotating stirring device is movably connected to the center of the cross-shaped base.

[0010] As a preferred embodiment of the present invention, the rotary stirring device includes: A motor mount is installed at the center of the top of the upper cover. A servo drive source is mounted on the top of the motor mount, and a rotating rod is connected to the output end of the servo drive source. The rotating rod extends to the inner side of the stirring liner and is rotatably connected to the center inside the cross base. An outer retaining ring is installed on the outside of the rotating rod. A telescopic rod extending to the outside is slidably connected inside the outer retaining ring. A side positioning block is fixed to the side of the telescopic rod by screws.

[0011] As a preferred embodiment of the present invention, a telescopic spring is provided on the outer side of the telescopic rod, the telescopic spring is connected to the side of the side positioning block, and a brush structure is detachably installed on the side of the side positioning block.

[0012] As a preferred embodiment of the present invention, the circulating dosing device includes: A vertical central pipe is provided inside the circulation channel, and an inclined pipe is connected to one side of the top of the vertical central pipe, which extends into the interior of the stirring liner. A horizontal pipe is connected to one side of the top of the vertical central pipe, the horizontal pipe extends to the outside of the waste liquid treatment tank, and an inlet is connected to one side of the top of the horizontal pipe. A horizontal hydraulic cylinder is installed on the outside of the horizontal pipe, and an injection piston is connected to the output end of the horizontal hydraulic cylinder. The injection piston is movably disposed inside the horizontal pipe. The feed nozzle is connected to the medicine storage tank via a flexible hose.

[0013] In a preferred embodiment of the present invention, a baffle plate located below the inclined pipe is installed inside the vertical central pipe, and a vertical electric cylinder is installed inside the baffle plate.

[0015] Compared with existing technologies, one or more of the above technical solutions have the following beneficial effects: 1. In medical laboratory wastewater treatment equipment, reagents are extruded and conveyed into the inner tank via compression, where they come into contact with the wastewater already inside. The wastewater and reagents are then mixed through stirring, treating (neutralizing) the wastewater and achieving the treatment of medical laboratory wastewater. Alternatively, when treating wastewater with reagents, the wastewater can be extracted and conveyed back to the center of the inner tank, where it is remixed with the reagents and the original wastewater. This maximizes the contact area between the reagents and the wastewater, maintaining a stable concentration gradient in the wastewater treatment reaction system and preventing localized issues of excessively high or low reagent concentrations. Simultaneously, repeated contact and thorough mixing of the wastewater and reagents within the system improves reaction efficiency and ensures the reagents function effectively. 2. In the medical laboratory waste liquid treatment equipment, when treating medical laboratory waste liquid, a servo drive source rotates the side positioning block (vertically), causing the waste liquid and reagents inside the inner tank to rotate vertically (stir), thus achieving the stirring and mixing operation of the waste liquid and reagents. Simultaneously, as the side positioning block rotates, the brush structure mounted on its side also rotates, cleaning the inner wall of the inner tank and preventing impurities in the waste liquid from adhering to the inner wall of the inner tank. 3. In the medical laboratory waste liquid treatment equipment, the treated liquid (after neutralization by reagents) can be drawn out from the inside of the waste liquid treatment tank by the pumping force generated by the liquid pump, and then transferred to the subsequent purification equipment through the discharge pipeline, which facilitates the continuous medical laboratory waste liquid treatment operation.

[0019] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0020] Please see Figures 1-9 A medical laboratory waste liquid treatment device includes a waste liquid treatment tank 10; a support leg 20 mounted on the outer side of the bottom of the waste liquid treatment tank 10 by screws; a waste liquid stirring and dosing treatment structure 30 mounted on the top of the waste liquid treatment tank 10 and extending into the interior, the waste liquid stirring and dosing treatment structure 30 extending to the outer side of the waste liquid treatment tank 10, and a drain pipe 40 connected to the bottom of the waste liquid treatment tank 10. The waste liquid stirring and dosing treatment structure 30 includes: an inner liner structure 301 disposed at the bottom of the waste liquid treatment tank 10; a rotary stirring device 302 installed inside the inner liner structure 301 and extending to the outer side of the top of the waste liquid treatment tank 10, a brush structure 303 installed on the outer side of the rotary stirring device 302; and a circulating dosing device 304 installed inside the inner liner structure 301 and extending to the outer side of the waste liquid treatment tank 10, the circulating dosing device 304 being connected to a drug storage tank via a hose.

[0021] It should be noted that the top of the waste liquid treatment tank 10 is fitted with a top cover 101 by screws, and a rotary stirring device 302 is installed on the top of the top cover 101. A waste liquid inlet pipe 102 is connected to one side of the top of the waste liquid treatment tank 10, and an observation window 103 is connected to one side of the bottom of the waste liquid treatment tank 10.

[0022] The working principle is as follows: When treating medical laboratory waste liquid, the waste liquid is transferred to the interior of the waste liquid treatment tank 10 through the waste liquid inlet pipe 102 and enters the interior of the inner tank structure 301. At this time, the treatment solution for the waste liquid is added to the interior of the inner tank structure 301 through the circulating dosing device 304, mixing with the treatment solution already in the inner tank structure 301. Then, the rotary stirring device 302 is activated to mix the added treatment solution and waste liquid, improving the treatment (neutralization) effect and efficiency of the medical laboratory waste liquid (by increasing the contact area). Simultaneously, the circulating dosing device 304 can extract the waste liquid and transfer it to the middle of the inner tank structure 301 through circulation, ensuring that the treatment solution circulates within the inner tank structure 301. The treated liquid can be discharged through the drain pipe 40.

[0023] It should be noted that the circulating waste liquid stirring and neutralization process can maintain a stable concentration gradient in the waste liquid treatment reaction system, avoiding problems such as excessively high or low local concentrations. It also helps to maintain constant conditions for the waste liquid neutralization reaction.

[0024] For details, please refer to the following: Figure 6 , Figure 7 and Figure 8 The inner liner structure 301 includes a cross base 3011, which is installed at the bottom of the waste liquid treatment tank 10. A stirring inner liner 3012 is installed on the outer side of the top of the cross base 3011. An upper annular baffle 3013 is installed on the top of the stirring inner liner 3012 by screws. The upper annular baffle 3013 is installed on the inner side of the waste liquid treatment tank 10. An annular circulation channel 3014 is formed between the outer side of the stirring inner liner 3012 and the inner side of the waste liquid treatment tank 10.

[0025] In this design, a circulating dosing device 304 is installed on one side of the inner mixing tank 3012, and multiple flow ports 30111 are opened at the eccentric part of the inner cross base 3011. A rotating stirring device 302 is movably connected to the center of the inner cross base 3011.

[0026] In the medical testing waste liquid treatment equipment of the present invention, the design of the circulation channel 3014 allows the waste liquid located at the bottom of the waste liquid treatment tank 10 to re-enter the (circulating) stirring inner tank 3012 through the circulation dosing device 304, thereby realizing the circulation and transfer operation of the waste liquid.

[0027] For details, please refer to the following: Figure 6 and Figure 7The rotary stirring device 302 includes a motor base 3021, which is installed at the center of the top of the upper cover 101. A servo drive source 3022 is installed on the top of the motor base 3021. The output end of the servo drive source 3022 is connected to a rotating rod 3023, which extends to the inner side of the stirring liner 3012 and is rotatably connected to the center of the cross base 3011. An outer retaining ring 3024 is installed on the outside of the rotating rod 3023. A telescopic rod 3025 extending to the outside is slidably connected inside the outer retaining ring 3024. A side positioning block 3026 is fixed to the side of the telescopic rod 3025 by screws.

[0028] In this design, a telescopic spring 30251 is provided on the outer side of the telescopic rod 3025. The telescopic spring 30251 is connected to the side of the side positioning block 3026. A brush structure 303 is detachably installed on the side of the side positioning block 3026.

[0029] In the medical testing waste liquid treatment equipment of the present invention, when the waste liquid and the reagent are stirred and mixed, the servo drive source 3022 is activated to drive the rotating rod 3023 connected to the output end of the servo drive source 3022 to rotate, and the outer retaining ring 3024 installed on the outside of the rotating rod 3023 also rotates. At this time, when the outer retaining ring 3024 rotates, the side positioning block 3026 and the brush structure 303 connected inside it through the telescopic rod 3025 can rotate (vertically), stirring and mixing the reagent and waste liquid located inside the stirring tank 3012.

[0030] It should be noted that the brush structure 303 is designed to clean the inner wall of the mixing tank 3012.

[0031] For details, please refer to the following: Figure 7 , Figure 8 and Figure 9 The circulating dosing device 304 includes a vertical central pipe 3041, which is located inside the circulation channel 3014. One side of the top of the vertical central pipe 3041 is connected to an inclined pipe 3042, which extends to the inside of the stirring tank 3012. A horizontal pipe 3043 is connected to one side of the top of the vertical central pipe 3041 and extends to the outside of the waste liquid treatment tank 10. One side of the top of the horizontal pipe 3043 is connected to an inlet 3044. A horizontal hydraulic cylinder 3045 is installed on the outside of the horizontal pipe 3043. The output end of the horizontal hydraulic cylinder 3045 is connected to an injection piston 3046, which is movably located inside the horizontal pipe 3043. The inlet 3044 is connected to the storage tank via a hose.

[0032] In the medical testing waste liquid treatment device of the present invention, when the treatment solution is added to the inside of the stirring tank 3012, the solution is transferred to the inside of the horizontal pipe 3043 through the inlet 3044. Then, the horizontal hydraulic cylinder 3045 is activated, causing the injection piston 3046 connected to the output end of the horizontal hydraulic cylinder 3045 to extend and retract inside the horizontal pipe 3043. This pushes the solution on the side of the injection piston 3046 into one side of the inclined pipe 3042, and then transfers it to the inside of the stirring tank 3012 through the inclined pipe 3042.

[0033] For details, please refer to the following: Figure 7 , Figure 8 and Figure 9 The vertical central pipe 3041 has a baffle 30411 installed inside, located below the inclined pipe 3042. The baffle 30411 has a vertical electric cylinder 30412 installed inside, and the output end of the vertical electric cylinder 30412 is connected to a vertical piston 30413. The vertical piston 30413 is movably connected inside the vertical central pipe 3041. The side of the vertical central pipe 3041 is connected to a circulation pipe 30414, which extends into the stirring inner tank 3012. The circulation pipe 30414 and the inclined pipe 3042 are equipped with a one-way valve 300. A one-way liquid extraction valve 3001 is installed at the bottom of the vertical central pipe 3041.

[0034] In the medical laboratory waste liquid treatment device of the present invention, when the waste liquid is circulated, the water pressure of the waste liquid forces it to enter the interior of the vertical central pipe 3041 through the one-way suction valve 3001. Then, the vertical electric cylinder 30412 is activated, causing the vertical piston 30413 connected to the output end of the electric cylinder 30412 to extend and retract within the vertical central pipe 3041. The piston movement generates a suction force that transfers the waste liquid to the interior of the circulation pipe 30414, and then the waste liquid is transferred back to the interior of the stirring tank 3012 through the circulation pipe 30414.

[0035] It should be noted that the design of the one-way valve 300 ensures the one-way transfer of medicine and waste liquid.

[0036] For details, please refer to the following: Figure 3 A liquid pump 401 is connected to the side of the vent pipe 40 by screws, and the outlet of the liquid pump 401 is connected to the discharge pipe 402.

[0037] In the medical testing waste liquid treatment equipment of the present invention, the treated liquid can be transported through the drain pipe 40 to the inside of the discharge pipe 402 by the power (pushing force) generated by the liquid pump 401, so as to realize the discharge operation of the liquid.
