Description

Technical Field

[0001] This utility model relates to the field of waste liquid treatment technology, specifically to a medical testing waste liquid collection and purification device. Background Technology

[0002] With the rapid development of medical testing technology and the widespread application of various laboratory testing equipment and reagents, a large amount of medical testing waste liquid is generated in daily operations. This waste liquid typically contains various harmful substances, including chemical reagents, biological pollutants, and heavy metals. Direct discharge of such waste liquid poses a serious threat to the environment and human health. Therefore, the safe collection and treatment of medical testing waste liquid has become a crucial aspect of laboratory management.

[0003] Laboratory waste mainly comes from specimens such as blood, urine, feces, and sputum, disposable items such as plastics and glass, and waste liquids discharged from chemical reagents and instruments during experiments. Most of the waste liquids and wastes discarded by hospital laboratories contain pathogens, bacteria, and harmful components. To prevent waste liquids from polluting the environment and spreading diseases, they are generally stored in a container and purified through sedimentation, or by adding strong oxidants (such as ozone, hydrogen peroxide, chlorine dioxide, etc.) to gradually degrade the organic matter in the waste liquid into simple inorganic substances, or to oxidize pollutants dissolved in water into substances that are insoluble in water and easily separated from the water.

[0004] A search revealed that prior art publication number CN119038730A discloses a medical laboratory waste liquid collection and purification device, including a purification tank and a treatment cylinder. A conveying pipe is rotatably connected to one side wall of the treatment cylinder, and the outer wall of the conveying pipe is rotatably connected to the interior of the purification tank. The interior of the conveying pipe is connected to the interior of the treatment cylinder. This medical laboratory waste liquid collection and purification device, when oxidizing the waste liquid, can drive a second drive motor to move a filter disc back and forth within the treatment cylinder to push and carry out intermediate products or precipitates generated during the oxidation process, preventing them from mixing with the waste liquid and hindering the effective contact between the oxidant and pollutants in the waste liquid. At the same time, the first drive motor drives the treatment cylinder to rotate intermittently, ensuring the filtration effect of the waste liquid.

[0005] Therefore, based on the above search and combined with existing technology, the existing medical testing waste liquid collection and purification device uses a strong oxidant gas to oxidize the waste liquid through contact with the surface of the waste liquid. However, the limited contact area leads to a decrease in oxidation efficiency, which in turn reduces the efficiency of waste liquid treatment. Utility Model Content

[0006] The purpose of this invention is to provide a medical testing waste collection and purification device to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A medical testing waste liquid collection and purification device includes an installation box. A door is hinged to the front end of the installation box. A treatment cylinder is fixedly installed inside the door. A stirring sleeve is rotatably connected to the center of the top surface of the treatment cylinder. A power component is installed after the top of the stirring sleeve passes through the top wall of the installation box. An air intake component is fixedly installed inside the stirring sleeve. The air intake component includes a main pipe. The top of the main pipe is fixedly connected to the top wall of the installation box. An air pump is fixedly installed at the top of the main pipe. The end of the air pump away from the main pipe is connected to an air storage cylinder through an air supply pipe. The air storage cylinder is fixedly installed on the outer wall of the installation box.

[0009] Furthermore, the top of the mixing sleeve is integrally formed with an installation plate, and the outer wall of the mixing sleeve is provided with several through holes at equal intervals around the circumference. At the intervals between several sets of through holes, the outer wall of the mixing sleeve is provided with several mixing blades at equal intervals around the circumference.

[0010] Furthermore, the power assembly includes a rotating disk, which is coaxially and fixedly mounted with a mounting plate, and a gear ring is coaxially and fixedly mounted on the outer wall of the rotating disk.

[0011] Furthermore, a drive gear is rotatably connected to the top surface of the processing cylinder on one side of the gear ring. A motor is coaxially fixedly mounted on the drive gear, and the drive gear meshes with the gear ring for transmission.

[0012] Furthermore, a connecting pipe is fixedly installed at the bottom of the main pipe, and exhaust pipes are fixedly connected to both ends of the connecting pipe. Several exhaust holes are equidistantly opened on the outer circumference of the exhaust pipe.

[0013] Furthermore, a spring is fixedly installed on the inner wall of the main pipe, and an abutment ring is integrally formed on the main pipe directly above the spring. A ball valve is sandwiched between the abutment ring and the spring.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] In this invention, a strong oxidizing agent gas is introduced into the main pipe via an air pump. The air pressure pushes the ball valve to disengage from the contact ring, allowing the strong oxidizing agent gas to enter the exhaust pipe through the connecting pipe. The gas then comes into full contact with the waste liquid in the treatment tank through several exhaust holes on the exhaust pipe. A motor drives the stirring sleeve to rotate synchronously, and the stirring blades agitate the liquid in the treatment tank, ensuring that the strong oxidizing agent gas and the waste liquid react fully. This gradually degrades and oxidizes the organic matter in the waste liquid. This device can fully mix and agitate the strong oxidizing agent gas and the waste liquid, improving the efficiency of waste liquid treatment. Attached Figure Description

The gas storage cylinder 7 is fixedly installed on the outer wall of the mounting box 1. Specifically, a mounting frame 12 is welded and fixed to the outer wall of the mounting box 1. The gas storage cylinder 7 is fixedly installed inside the mounting frame 12.

[0025] The top of the stirring sleeve 3 is integrally formed with an installation plate 31. The outer wall of the stirring sleeve 3 has several through holes 32 equidistantly opened around its circumference. At intervals between the several sets of through holes 32, several stirring blades 33 are equidistantly arranged around the outer wall of the stirring sleeve 3. Specifically, the stirring sleeve 3 is installed in the processing cylinder 2 and the liquid is stirred by the several stirring blades 33.

[0026] The power assembly 4 includes a rotating disk 41, which is coaxially fixedly installed with the mounting plate 31. Specifically, the top surface of the rotating disk 41 has several weight-reducing grooves equidistantly spaced around its circumference. The outer wall of the mounting plate 31 is integrally formed with protrusions, and the inner wall of the rotating disk 41 has grooves that are matched in size with the protrusions. The protrusions limit the grooves, allowing the stirring sleeve 3 and the rotating disk 41 to rotate synchronously. A gear ring 42 is coaxially fixedly installed on the outer wall of the rotating disk 41. The top surface of the processing cylinder 2 is rotatably connected to a drive gear 43 on one side of the gear ring 42. A motor 44 is coaxially fixedly installed on the drive gear 43. Specifically, the top surface of the processing cylinder 2 is welded and fixedly fixed with a mounting arm 22. The drive gear 43 is rotatably connected to the end of the mounting arm 22.

The drive gear 43 and the gear ring 42 mesh and drive each other.

[0027] Example 2: Please refer to Figures 4-6A medical testing waste liquid collection and purification device, which differs from Embodiment 1, has a connecting pipe 52 fixedly installed at the bottom of the main pipe 51, and exhaust pipes 53 fixedly connected to both ends of the connecting pipe 52. Specifically, the outer wall of the connecting pipe 52 is integrally formed with three connection ports, and the inner wall of the connection ports is provided with internal threads. The two exhaust pipes 53 and the main pipe 51 are respectively threaded to the three connection ports. The outer walls of the two exhaust pipes 53 and the main pipe 51 are provided with limiting rings, and a sealing ring is sandwiched between the limiting ring and the end face of the connection port. The outer wall of the exhaust pipe 53 is provided with a plurality of exhaust holes 531 at equal intervals around its circumference.

[0028] A spring 54 is fixedly installed on the inner wall of the main pipe 51. Specifically, a fixing ring is integrally formed on the inner wall of the main pipe 51, and the bottom end of the spring 54 abuts against the top surface of the fixing ring. An abutting ring 512 is integrally formed on the main pipe 51 directly above the spring 54. A ball valve 55 is sandwiched between the abutting ring 512 and the spring 54. Specifically, the outer wall of the ball valve 55 abuts against the top end of the spring 54 and the bottom end of the abutting ring 512. The ball valve 55 forms a one-way valve, which can prevent the liquid in the treatment cylinder 2 from flowing back into the main pipe 51.

[0029] Working principle: The waste liquid to be treated is fed into the treatment cylinder 2 through the inlet 21. The air pump 6 is started. The air pump 6 feeds the strong oxidant gas in the gas storage bottle 7 into the main pipe 51 through the gas supply pipe 61. The strong oxidant gas pushes the ball valve 55 with air pressure, causing it to disengage from the contact ring 512. At this time, the spring 54 is compressed. The strong oxidant gas enters the exhaust pipe 53 through the connecting pipe 52 and comes into contact with the waste liquid in the treatment cylinder 2 through several exhaust holes 531 on the exhaust pipe 53.

[0030] The motor 44 is started, and the motor 44 drives the gear ring 42 to rotate through the drive gear 43. The gear ring 42 drives the stirring sleeve 3 to rotate synchronously through the rotating disk 41. Since the air intake component 5 is installed inside the stirring sleeve 3, the strong oxidant gas escapes to the outer wall of the stirring sleeve 3 through the through hole 32 opened on the stirring sleeve 3. When the stirring sleeve 3 rotates, the stirring blades 33 on its outer wall stir the liquid in the treatment tank 2, so that the strong oxidant gas reacts fully with the waste liquid, gradually degrading the organic matter in the waste liquid into simple inorganic matter, or oxidizing pollutants dissolved in water into substances that are insoluble in water and easy to separate from water; at this point, the operation of this device is completed.

[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the scope of the technology disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
