Description

Technical Field

[0001] This utility model relates to the field of medical waste treatment technology, and in particular to a pollutant detection device for medical waste treatment. Background Technology

[0002] Medical waste treatment is the process of classifying, collecting, properly storing, professionally transporting, and safely disposing of various hazardous wastes generated by medical and health institutions, including infectious and pathological wastes. In order to detect whether the pollutants have been completely treated and the treatment effect, a pollutant detection device for medical waste treatment is needed.

[0003] Pollutant detection devices for medical waste treatment refer to specialized instruments and equipment designed for the accurate detection and analysis of various pollutants generated and remaining during the medical waste treatment process. They can perform qualitative and quantitative detection of harmful gas components in the exhaust gas emitted by medical waste treatment facilities, ensuring that exhaust gas emissions meet environmental protection and health safety standards.

[0004] Currently available medical waste treatment contaminant detection devices use a water pump to draw wastewater from a wastewater tank into a detection chamber, and then use a detector to detect the degree of contamination. However, in actual use, the wastewater level in the wastewater tank changes due to the continuous inflow of new wastewater and the evaporation or sampling during the treatment process. When the wastewater level drops, the pump outlet may be exposed to the air, making it impossible to extract wastewater samples. Conversely, when the wastewater level rises, the pump outlet may be submerged too deeply, resulting in samples that do not meet requirements or damage to the pumping equipment due to excessively high liquid levels, thus reducing the reliability of the device. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a pollutant detection device for medical waste treatment, aiming to improve the problem that existing detection devices cannot adapt to changes in sewage level when adjusting the extraction of sewage samples.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a pollutant detection device for medical waste treatment, comprising a waste liquid tank, a detection box fixedly connected to the top of the waste liquid tank, a water pump connected to the left side of the detection box, a flexible hose connected to the bottom end of the water pump, a hollow block fixedly connected to the left side of the inner wall of the waste liquid tank, a first bevel gear rotatably connected to the left end of the inner wall of the hollow block, and a second bevel gear rotatably connected to the rear bottom side of the inner wall of the hollow block, the second bevel gear meshing with the first bevel gear. A threaded rod is fixedly connected to the bottom of the hollow block, and a base plate is rotatably connected to the bottom of the threaded rod. The bottom of the base plate is fixedly connected to the waste liquid tank. A lifting ring is threadedly connected to the outer side of the threaded rod, and a locking block is rotatably connected to the outer side of the lifting ring. A cross rod is rotatably connected to the front side of the bottom of the inner wall of the hollow block, and a float is slidably connected to the outer side of the cross rod. The outer side of the hose passes through the waste liquid tank and is fixedly connected to the float. The locking block engages with the float. A detection mechanism is provided inside the detection box to improve the detection effect.

[0007] As a further description of the above technical solution:

[0008] The detection mechanism includes a motor, which is fixedly connected to the top of the detection box. The output end of the motor passes through the detection box and is fixedly connected to a first mixing blade. A third bevel gear is rotatably connected to the left and right sides of the bottom of the inner wall of the first mixing blade. A second mixing blade is rotatably connected to the bottom of the first mixing blade. A fourth bevel gear is fixedly connected to the top of the second mixing blade. The fourth bevel gear meshes with the third bevel gear. A detector is rotatably connected to the bottom of the second mixing blade. The bottom of the detector is fixedly connected to the detection box.

[0009] As a further description of the above technical solution:

[0010] The outer walls of the testing box are all fixedly connected to brackets, and the bottom of the brackets is fixedly connected to the waste liquid tank.

[0016] The bottom of the outer wall of the waste liquid tank is fixedly connected with positioning blocks, and positioning holes are opened on the outer side of the positioning blocks.

[0017] As a further description of the above technical solution:

[0021] This utility model has the following beneficial effects:

[0022] 1. In this utility model, the bottom of the hose moves with the liquid surface by means of buoyancy using a float. The water pump draws sewage from the surface of the hose through the hose, preventing hose malfunctions caused by changes in liquid level. After the locking block engages with the float, the bevel gear rotates, and through meshing transmission, it drives related components to move the lifting ring up and down via the threaded connection, thereby manually adjusting the position of the hose to ensure stable and compliant sewage extraction. This allows the device to adapt to changes in sewage level for easy extraction of sewage samples for testing, thus improving the reliability of the device.

[0023] 2. In this utility model, after the motor is started, the mixing blade rotates and drives the inner bevel gear to rotate synchronously. Through meshing transmission, the other bevel gear and the mixing blade rotate along its bottom. The two blades work together to stir the waste liquid in the detection box. The detector is used to detect the fully mixed wastewater, which effectively improves the detection accuracy and thus improves the practicality of the device. Attached Figure Description

[0033] Reference Figure 1 , Figure 2 and Figure 5 The detection mechanism 2 includes a motor 201, which is fixedly connected to the top of the detection box 3. The output end of the motor 201 passes through the detection box 3 and is fixedly connected to a first mixing blade 202. Starting the motor 201 can drive the first mixing blade 202 to rotate. The bottom left and right sides of the inner wall of the first mixing blade 202 are rotatably connected to a third bevel gear 203. When the first mixing blade 202 rotates, it can drive the third bevel gear 203 to rotate. The bottom of the first mixing blade 202 is rotatably connected to a second mixing blade 204. The top of the second mixing blade 204 is fixedly connected to a fourth bevel gear 205. The fourth bevel gear 205 meshes with the third bevel gear 203.

The bottom of the second mixing blade 204 is rotatably connected to a detector 206. The bottom of the detector 206 is fixedly connected to the detection box 3. The wastewater in the device can be detected by the detector 206.

[0034] Reference Figure 2 , Figure 3 and Figure 5The outer walls of the detection box 3 are all fixedly connected with brackets 20. The bottom of the brackets 20 is fixedly connected to the waste liquid tank 1. The brackets 20 can improve the structural strength of the fixed connection between the detection box 3 and the waste liquid tank 1. A knob 15 is rotatably connected to the top left side of the waste liquid tank 1. The outer side of the knob 15 passes through the waste liquid tank 1 and is fixedly connected to the first bevel gear 7. The first bevel gear 7 can be easily rotated by operating the knob 15.

Holding the handle 16 can facilitate the handling and storage of the device, and the protective sleeve 17 can improve the comfort of holding it.

[0035] Reference Figure 1 , Figure 2 and Figure 3 Positioning blocks 18 are fixedly connected to the bottom of the outer wall of the waste liquid tank 1. Positioning holes 19 are opened on the outer side of the positioning blocks 18. By installing threaded parts in the positioning holes 19 on the positioning blocks 18, the device can be easily installed and fixed. The top right side of the waste liquid tank 1 is connected to the feeding trough 22. The outer side of the feeding trough 22 is provided with a movable door 23. The outer side of the movable door 23 is fixedly connected to the hinge 24. The movable door 23 is rotatably connected to the feeding trough 22 through the hinge 24.

A controller 21 is fixedly connected to the middle of the front side of the waste liquid tank 1. The controller 21 is electrically connected to the water pump 4, the motor 201 and the detector 206 respectively. The controller 21 can control the start and operation of the water pump 4, the motor 201 and the detector 206 respectively.

[0036] Working principle: Before using the device, the buoyancy of the float 13 can drive the bottom of the hose 5 to move up and down. Since the float 13 will remain at the level of the liquid surface, the water pump 4 is started to draw water through the hose 5. This can keep the sewage at the liquid surface being drawn, preventing the hose 5 from being exposed to the air when the sewage level drops, and preventing the hose 5 from being submerged too deeply when the sewage level rises, resulting in samples that do not meet the requirements. Furthermore, by moving the locking block 11 along the lifting ring 10 and engaging with the float 13, the first bevel gear 7 can be rotated through meshing transmission, driving the second bevel gear 8 and its threaded rod 9 to rotate along the base plate 14. The lifting ring 10 can be moved up and down through the threaded connection to manually adjust the position of the hose 5.

[0037] Furthermore, the starting motor 201 can drive the first mixing blade 202 to rotate. When the first mixing blade 202 rotates, it will synchronously drive the third bevel gear 203 inside it to rotate. Through meshing transmission, it will drive the fourth bevel gear 205 and the second mixing blade 204 above it to rotate along the bottom of the first mixing blade 202. The waste liquid in the detection box 3 can be mixed by the rotation of the first mixing blade 202 and the second mixing blade 204, and the uniformly mixed wastewater can be detected by the detector 206, thereby improving the detection accuracy.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
