[0002] With the continuous progress of modern medicine, the number of medical testing items is increasing, including clinical chemistry testing, hematology testing, microbiology testing and many other fields. These testing processes will generate a large amount of waste liquid, such as chemical testing waste liquid containing heavy metals (such as mercury, cadmium, lead, etc.), microbiological testing waste liquid containing pathogens, and biochemical testing waste liquid containing various chemical reagents.

[0003] The existing medical waste liquid cannot be fully mixed with chemical agents during purification, so the precipitant cannot come into contact with all the heavy metal ions, resulting in the inability to precipitate some heavy metal ions, causing the heavy metal content in the purified waste liquid to exceed the standard, affecting the balance of the ecosystem. At the same time, insufficient mixing will make the purification process more complicated and lengthy, reducing the waste liquid treatment efficiency. Summary of the invention

[0012] Furthermore, a groove is provided on the inner upper surface of the waste liquid treatment chamber, and a rotating column is slidably connected to the outer wall of the rotating rod and located above the hollow rod. A cam groove is integrally formed on the outer wall of the rotating column, and an L-shaped limit rod is fixedly connected to the right side of the inner upper surface of the groove, and the left end of the L-shaped limit rod is slidably connected to the inside of the cam groove.

[0023] In order to make the technical solution of the present invention clearer, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0024] Example

[0025] like Figure 1 As shown, a plurality of supporting legs 10 are fixedly connected to the lower surface of the base plate 1;

[0026] By setting a plurality of supporting legs 10 evenly distributed below the bottom plate 1, a stable support is provided for the entire device, thereby improving the stability of the device.

[0027] like Figure 1 As shown, a medical test waste liquid collection and purification treatment device is provided, comprising a bottom plate 1, a reaction box 2 is fixedly connected to the upper surface of the bottom plate 1, a waste gas purification box 3 is fixedly connected to the upper surface of the bottom plate 1 and located on the right side of the reaction box 2, a waste liquid barrel 4 is arranged on the upper surface of the bottom plate 1 and located on the left side of the reaction box 2, and a medicine barrel 5 is arranged on the upper surface of the bottom plate 1 and located behind the waste liquid barrel 4;

[0028] Various types of waste liquid generated by medical examinations are collected into waste liquid barrels 4 for temporary storage through special pipelines or manual transportation. Specific treatment agents for the components of medical examination waste liquid are pre-stored in the agent barrels 5. These agents are used to adjust the pH value of the waste liquid, precipitate harmful substances, oxidize and decompose organic pollutants, etc. According to the properties of the waste liquid and the treatment requirements, the agents in the agent barrels 5 can be quantitatively added to the reaction box 2. In the reaction box 2, the pollutants in the waste liquid undergo a series of chemical reactions with the agents. By adding precipitants, heavy metal ions are precipitated and separated from the waste liquid. At the same time, when the chemical reaction is carried out in the reaction box 2, some waste gas may be generated. The waste gas generated in the reaction box 2 is introduced into the waste gas purification box 3 through a pipeline. The waste gas is purified by the waste gas purification box 3 and discharged into the atmosphere after meeting the emission standards.

[0029] like Figure 1As shown, the front surface of the waste liquid barrel 4 and the front surface of the medicine barrel 5 are both provided with scale lines 26;

[0030] The scale lines 26 on the outside of the waste liquid barrel 4 can intuitively display the storage volume of the waste liquid in the barrel. When collecting waste liquid, laboratory staff can clearly understand the volume of the waste liquid by observing the scale lines 26 at any time. When the waste liquid is close to the maximum capacity marked by the scale lines 26, the staff can make timely treatment arrangements to avoid overflow due to excessive waste liquid, thereby ensuring the safety of the laboratory environment. The scale lines 26 on the outside of the reagent barrel 5 make it convenient for the staff to observe the use of the internal reagents in real time from the outside. When the reagents are too little, a certain amount of chemical reagents can be added to the inside to improve the efficiency of waste liquid treatment.

[0031] like Figure 1 and Figure 2 As shown, the upper surface of the waste liquid barrel 4 and the upper surface of the medicine barrel 5 are both provided with sealing covers 6, and the upper surfaces of the two sealing covers 6 are both threadedly connected with delivery pipes 7, and liquid pumps 8 are symmetrically fixedly connected to the upper left side of the reaction box 2, and the input ends of the two liquid pumps 8 are respectively threadedly connected to the right ends of the two delivery pipes 7, and the interior of the reaction box 2 is integrally formed with a waste liquid treatment chamber 9, and the output ends of the two liquid pumps 8 are both connected to the interior of the waste liquid treatment chamber 9;

[0032] By removing the sealing cover 6 on the top of the waste liquid barrel 4, the inspection waste liquid can be collected inside the waste liquid barrel 4, and by removing the sealing cover 6 on the medicine barrel 5, it is convenient to add the medicine. The waste liquid in the waste liquid barrel 4 and the medicine in the medicine barrel 5 can be quantitatively transported to the inside of the waste liquid treatment chamber 9 in a certain proportion through two liquid pumps 8. In the waste liquid treatment chamber 9, the waste liquid and the medicine are fully mixed and a chemical reaction occurs.

[0033] like Figure 1 As shown, an observation window 18 is provided below the front surface of the reaction box 2, and a central control screen 19 is provided above the front surface of the reaction box 2;

[0034] The operator can visually view the reaction between the waste liquid and the reagent inside the waste liquid treatment chamber 9 through the observation window 18. At the same time, the operator can start and stop the two liquid pumps 8 and adjust the delivery flow of the two liquid pumps 8 on the central control screen 19 without directly contacting the equipment, which greatly improves the convenience and safety of operation.

[0035] like Figure 2As shown, the upper surface of the reaction box 2 is fixedly connected with a motor box 11, the inner upper surface of the motor box 11 is fixedly connected with a rotating motor 12, the bottom end of the output shaft of the rotating motor 12 is fixedly connected with a rotating rod 13, the bottom end of the rotating rod 13 extends to the bottom of the waste liquid treatment chamber 9, the outer wall of the rotating rod 13 is sleeved with a hollow rod 14, the outer wall of the hollow rod 14 is provided with a plurality of stirring blades 15, the inner lower surface of the waste liquid treatment chamber 9 is provided with an L-shaped drain pipe 16, the left end of the L-shaped drain pipe 16 extends to the left side of the bottom plate 1, and the inside of the L-shaped drain pipe 16 is provided with an electronic valve 17;

[0036] When the waste liquid and chemical agents are added into the waste liquid treatment chamber 9 in a certain proportion, the rotating motor 12 is started to control the rotation of the rotating rod 13, and the rotating rod 13 can drive the multiple stirring blades 15 on the outside to rotate through the hollow rod 14, so that the waste liquid and the agent mixture in the waste liquid treatment chamber 9 are fully stirred by the multiple stirring blades 15, so that the waste liquid and the agent can be more evenly contacted, which greatly accelerates the progress of the chemical reaction and ensures a more complete reaction. When the reaction is completed, the purified waste liquid can be discharged to the outside through the L-shaped discharge pipe 16 under the action of gravity by opening the set electronic valve 17. After the purified waste liquid is discharged, the set electronic valve 17 is closed to prepare for the next waste liquid purification work.

[0037] like Figure 2 , Figure 3 and Figure 5 As shown, a groove 27 is provided on the inner upper surface of the waste liquid treatment chamber 9, a rotating column 28 is slidably connected to the outer side wall of the rotating rod 13 and located above the hollow rod 14, and a cam slide groove 29 is integrally formed on the outer side wall of the rotating column 28. An L-shaped limiting rod 30 is fixedly connected to the right side of the inner upper surface of the groove 27, and the left end of the L-shaped limiting rod 30 is slidably connected to the inside of the cam slide groove 29. A limiting vertical groove 31 is symmetrically provided on the outer side wall of the rotating rod 13 and located inside the hollow rod 14, and a limiting slider 32 is symmetrically fixedly connected to the inner side wall of the hollow rod 14. The opposite sides of the two limiting sliders 32 are respectively slidably connected to the inside of the two limiting vertical grooves 31, and a connecting rod 33 is symmetrically fixedly connected to the upper surface of the hollow rod 14 and the lower surface of the rotating column 28;

[0038] When the rotating rod 13 is controlled to rotate by the rotating motor 12, the two limiting vertical grooves 31 cooperate with the two limiting sliders 32 on the inner wall of the hollow rod 14, so that the hollow rod 14 rotates synchronously with the rotating rod 13, so that the multiple stirring blades 15 rotate together. During the rotation process, the waste liquid and the mixed liquid of the medicine in the waste liquid treatment chamber 9 can be fully stirred to accelerate the chemical reaction. At the same time, the rotating rod 13 drives the rotating column 28 to rotate together. The cam groove 29 interacts with the L-shaped limiting rod 30 in the groove 27. As the rotating column 28 rotates, the mixing blades 15 rotate together. The L-shaped limit rod 30 slides in the cam groove 29, so that the rotating column 28 is displaced up and down during the rotation. The rotating column 28 is connected to the hollow rod 14 through the connecting rod 33, so the hollow rod 14 will move up and down with the up and down displacement of the rotating column 28 while rotating. The composite movement of the hollow rod 14, which is both rotating and moving up and down, enables the multiple stirring blades 15 to stir the mixed liquid at different height levels in the waste liquid treatment chamber 9 more comprehensively and three-dimensionally, thereby further promoting the uniform mixing of the waste liquid and the reagent and improving the reaction efficiency.

[0039] like Figure 4 As shown, the upper surface of the exhaust gas purification box 3 is detachably connected with a box cover 20, the internal front surface and rear surface of the exhaust gas purification box 3 are fixedly connected with a plurality of partitions 34, two filter plates 21 and two neutralizer plates 22 are respectively arranged between the plurality of partitions 34, an L-shaped air inlet pipe 23 is detachably connected between the left side of the upper surface of the box cover 20 and the upper right side of the interior of the waste liquid treatment chamber 9, a negative pressure fan 24 is arranged on the inner side wall of the L-shaped air inlet pipe 23, and an L-shaped discharge pipe 25 is detachably connected to the right side of the upper surface of the box cover 20;

[0040] When the waste liquid and chemical agents react inside the waste liquid treatment chamber 9, toxic waste gas is generated. The negative pressure fan 24 is started, and the negative pressure fan 24 generates a strong suction force to suck the waste gas inside the waste liquid treatment chamber 9 into the waste gas purification box 3 through the L-shaped air inlet pipe 23. Since the box cover 20 and the waste gas purification box 3 are detachably connected, and the L-shaped air inlet pipe 23 and the upper surface of the box cover 20 are also detachably connected, this design facilitates flexible assembly and disassembly of various components during equipment installation and maintenance. After the waste gas enters the waste gas purification box 3, it first contacts the filter plate 21. The filter plate 21 can effectively intercept solid particles, dust and other impurities in the waste gas, and the impurities are blocked by the filter plate 21. And remain on the plate, preliminarily purifying the exhaust gas. The preliminarily filtered exhaust gas continues to flow in the exhaust gas purification box 3, and then contacts the neutralizer plate 22. The neutralizer plate 22 is coated or filled with a neutralizer for the acidic or alkaline gas in the exhaust gas. The alkaline substance on the neutralizer plate 22 reacts with it to neutralize the acidic gas, converting it into harmless or less harmful substances such as salt and water. On the contrary, if there is alkaline gas in the exhaust gas, the acidic neutralizer will react with it. The setting of multiple partitions 34 increases the flow path of the exhaust gas in the purification box, and at the same time continues to filter the exhaust gas for the second time through the filter plate 21 and the neutralizer plate 22, further ensuring that the exhaust gas can be purified more purely.

[0041] The above-mentioned embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the present invention. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
