Description

Technical Field

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

[0002] Hospital waste refers to all waste that needs to be discarded and cannot be reused in hospitals, including biological and non-biological waste, as well as domestic waste. Medical waste refers to waste generated during the diagnosis, treatment, and care of patients. Medical waste may contain a large number of pathogenic microorganisms and harmful chemicals, and may even contain radioactive and damaging substances. Therefore, medical waste is an important risk factor for the spread of diseases or related public health problems.

[0003] A search revealed a Chinese patent disclosure for a multifunctional medical waste sorting and treatment device (authorization announcement number CN108339837B). The device includes a main body with a control console in the center of its outer surface. A pressure regulating valve and a hydraulic gauge are located above the main body's outer surface. An equipment box is located below the main body's outer surface, containing protective clothing and a fire extinguisher. A disinfection tank is located on the top of the main body. This patented technology, by incorporating a waste compressor, can separate chemical liquids from medical waste bottles, solving unnecessary troubles during sorting. The main body can be made of corrosion-resistant material, and its inner surface is rounded to prevent corrosion by acidic chemical liquids. It is easy to clean dead corners during disinfection and will not be damaged by sharp objects. A waste liquid bottle is included, which can be made of high-density polyethylene material, resistant to corrosion by acids, alkalis, and various salts, making it a suitable material for sorting and treating waste liquids.

[0004] However, the above-mentioned device still has some drawbacks in actual use. The most obvious one is that the medical waste sorting and treatment device uses a waste compressor to compress the medical waste in the waste box to achieve solid-liquid separation. However, the compression operation is completed on the upper conveyor belt. When the waste compressor head squeezes downward, it will cause the upper conveyor belt to bend. Over time, the upper conveyor belt is prone to loosening and breaking. In addition, the waste liquid is discharged through the drain hole opened in the upper conveyor belt. The waste liquid contains some corrosive substances, which will corrode the upper conveyor belt and affect the discharge effect of the drain hole. Utility Model Content

[0005] Given the existing problems in the medical waste sorting and treatment device, where the medical waste in the waste box is compressed by a waste compressor to achieve solid-liquid separation, but the compression operation is completed on the upper conveyor belt, the upper conveyor belt will bend when the waste compressor head squeezes downwards, and over time, the upper conveyor belt is prone to loosening and breakage. In addition, the waste liquid is discharged through the drain hole opened in the upper conveyor belt, and the waste liquid contains some corrosive substances, which will corrode the upper conveyor belt and affect the discharge effect of the drain hole. The main purpose of this utility model is to provide a medical waste sorting and treatment device.

[0006] The technical solution of this utility model is as follows: a medical waste sorting and processing device includes a processing box, a fixed plate fixedly connected inside the processing box, and mounting slots provided on both sides of the inner wall of the processing box above the fixed plate. A threaded rod is rotatably connected inside one of the mounting slots, and a fixed rod is fixedly connected inside the other mounting slot. A threaded block is threadedly connected to the outer side of the threaded rod, and a slider is slidably connected to the outer side of the fixed rod. A waste box is fixedly connected between the slider and the threaded block. The waste box is slidably connected to the top of the fixed plate, and abutment plates are fixedly connected to both sides of the waste box. A replacement mechanism is provided inside the fixed plate.

[0007] By adopting the above technical solution, the rotation of the threaded rod can drive the threaded block to move, thereby driving the waste box and the medical waste inside into the processing box. The upper conveyor belt in the comparative patent is replaced with a fixed plate. When the waste box travels to the middle of the processing box, the abutment plates on both sides of the waste box are always in contact with the fixed plate, so that the waste box remains stable after being squeezed by the waste compressor head, thus providing strong support for the waste box and preventing breakage.

[0008] In a preferred embodiment, the replacement mechanism includes an inlay groove formed inside the fixed plate, a replacement plate being engaged inside the inlay groove, a fixing groove being formed inside the fixed plate and at each of the four corners of the replacement plate, an embedded mounting block being engaged inside each fixing groove, the embedded mounting block being fixedly connected to the replacement plate, an embedded bolt being provided inside each embedded mounting block, the embedded mounting block being connected to the fixed plate by the embedded bolt, and an array of drainage holes inside the replacement plate.

[0009] By adopting the above technical solution, the embedded bolts and embedded mounting blocks facilitate the replacement and installation of damaged replacement plates. Furthermore, since the replacement plates and drain holes are in long-term contact with corrosive substances in the waste liquid, replacing the replacement plates avoids the need to replace the entire device due to corrosion of some components.

[0010] In a preferred embodiment, a disinfection tank is fixedly installed on the top of the treatment box, and water outlet pipes are fixedly connected at equal intervals to the outside of the disinfection tank. Spray nozzles are fixedly connected to the end of each water outlet pipe away from the disinfection tank, and a waste compressor is fixedly installed at the top of the inner wall of the treatment box.

[0011] By adopting the above technical solution, disinfectant can be sprayed into the waste box through the nozzle, allowing the disinfectant to come into contact with the medical waste. The medical waste in the waste box is then compressed by the waste compressor, achieving solid-liquid separation.

[0012] In a preferred embodiment, both ends of the processing box are rotatably connected to drive rollers, and a conveyor belt is connected between the two drive rollers. A waste liquid bottle is placed on top of the conveyor belt. A drain platform is fixedly connected to the bottom of the fixed plate and below the replacement plate. A drive motor is fixedly installed on the rear side of the processing box. The output shaft of the drive motor extends into the interior of the processing box and is fixedly connected to the central shaft of the corresponding drive roller.

[0013] By adopting the above technical solution, after solid-liquid separation, the waste liquid will fall into the drain platform through the drain hole in the replacement plate, and then flow into the corresponding waste liquid bottle, so as to achieve unified collection and treatment of waste liquid through the waste liquid bottle.

[0014] In a preferred embodiment, the sum of the widths of the waste box and the contact plate is greater than the width of the replacement plate, and the waste box is provided with water outlet holes at equal intervals around its perimeter, and the bottom of the inner wall of the waste box is provided with a slope that facilitates drainage.

[0015] By adopting the above technical solution and using the inclined surface, it is possible to facilitate the rapid discharge of waste liquid and reduce the residue of waste liquid in the waste box.

[0016] In a preferred embodiment, a servo motor is fixedly mounted on the outside of the processing box, and the output shaft of the servo motor extends into the interior of the mounting groove and is fixedly connected to the threaded rod.

[0017] By adopting the above technical solution, the rotation of the output shaft of the servo motor can drive the rotation of the threaded rod.

[0018] In a preferred embodiment, a controller, a hydraulic gauge, and a pressure regulating valve are fixedly installed on the outside of the processing box, and a hinged door is connected to the outside of the processing box.

[0019] By adopting the above technical solution and using a rotating door, the replacement plate inside the fixed plate can be replaced.

[0020] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0021] 1. In this utility model, the rotation of the threaded rod drives the threaded block to move, thereby driving the waste box and the medical waste inside into the processing box. Through the cooperation of the slider and the fixed rod, not only is the waste box more stable during movement, but it also provides a certain support force when the medical waste inside the waste box is squeezed. The upper conveyor belt in the comparative patent is replaced with a fixed plate. When the waste box travels to the middle of the processing box, the abutment plates on both sides of the waste box are always in contact with the fixed plate, so that the waste box remains stable after being squeezed by the waste compressor head, thereby providing strong support force for the waste box and preventing breakage.

[0022] 2. In this utility model, the embedded bolts and embedded mounting blocks facilitate the replacement and installation of damaged replacement plates. Since the replacement plates and drain holes are in long-term contact with corrosive substances in the waste liquid, replacing the replacement plates avoids the situation where the entire device needs to be replaced due to corrosion of some components. This reduces costs while ensuring the drainage effect of the drain holes. Attached Figure Description

[0028] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0029] Reference Figure 1-4 A medical waste sorting and processing device includes a processing box 1. A fixing plate 7 is fixedly connected inside the processing box 1. Mounting slots 12 are provided on both sides of the inner wall of the processing box 1 and above the fixing plate 7. A threaded rod 13 is rotatably connected inside one mounting slot 12, and a fixing rod 14 is fixedly connected inside the other mounting slot 12. A threaded block 11 is threadedly connected to the outside of the threaded rod 13, and a slider 10 is slidably connected to the outside of the fixing rod 14. A waste box 9 is fixedly connected between the slider 10 and the threaded block 11. The waste box 9 is slidably connected to the top of the fixing plate 7. A contact plate 8 is fixedly connected to both sides of the waste box 9. A replacement mechanism is provided inside the fixing plate 7.

[0030] In use, the rotation of the threaded rod 13 drives the threaded block 11 to move, thereby allowing the waste box 9 and the medical waste inside to enter the processing box 1. Through the cooperation of the slider 10 and the fixed rod 14, the waste box 9 is not only more stable during movement, but also provides a certain support when the medical waste inside the waste box 9 is squeezed. The upper conveyor belt in the comparative patent is replaced with a fixed plate 7. When the waste box 9 travels to the middle of the processing box 1, the abutment plates 8 on both sides of the waste box 9 are always in contact with the fixed plate 7, so that the waste box 9 remains stable after being squeezed by the head of the waste compressor 18, thereby providing strong support for the waste box 9 and preventing breakage.

[0031] Reference Figure 4 The replacement mechanism includes an inlay groove inside the fixed plate 7, in which a replacement plate 16 is snapped. Fixing grooves 19 are provided inside the fixed plate 7 at the four corners of the replacement plate 16. Embedded mounting blocks 21 are snapped into the fixing grooves 19. The embedded mounting blocks 21 are fixedly connected to the replacement plate 16. Embedded bolts 20 are provided inside the embedded mounting blocks 21. The embedded mounting blocks 21 are connected to the fixed plate 7 by the embedded bolts 20. Drainage holes 17 are arrayed inside the replacement plate 16.

[0032] In use, the embedded bolts 20 and embedded mounting blocks 21 facilitate the replacement and installation of damaged replacement plates 16. Since replacement plates 16 and drain holes 17 are in long-term contact with corrosive substances in waste liquid, replacing replacement plates 16 avoids the need to replace the entire device due to corrosion of some components. This reduces costs while ensuring the drainage effect of drain holes 17.

[0033] Reference Figure 2 A disinfection tank 5 is fixedly installed on the top of the treatment box 1. Water outlet pipes 6 are fixedly connected at equal intervals on the outside of the disinfection tank 5. Spray nozzles are fixedly connected to the end of the water outlet pipes 6 away from the disinfection tank 5. A waste compressor 18 is fixedly installed on the top of the inner wall of the treatment box 1.

[0034] In use, disinfectant can be sprayed into waste container 9 through the nozzle, allowing the disinfectant to come into contact with the medical waste. The waste compressor 18 then compresses the medical waste in waste container 9, achieving solid-liquid separation.

[0035] Reference Figure 2 Both ends of the processing box 1 are rotatably connected to drive rollers, and a conveyor belt 2 is connected between the two drive rollers. A waste liquid bottle 4 is placed on the top of the conveyor belt 2. A drain platform 22 is fixedly connected to the bottom of the fixed plate 7 and below the replacement plate 16. A drive motor is fixedly installed on the rear side of the processing box 1. The output shaft of the drive motor extends into the interior of the processing box 1 and is fixedly connected to the central shaft of the corresponding drive roller.

[0036] After solid-liquid separation, the waste liquid will fall into the drain platform 22 through the drain hole 17 in the replacement plate 16, and then flow into the corresponding waste liquid bottle 4. The waste liquid is collected and treated in a unified manner through the waste liquid bottle 4.

[0037] Reference Figure 4 The combined width of the waste box 9 and the contact plate 8 is greater than the width of the replacement plate 16. The waste box 9 has water outlet holes 3 at equal intervals around its perimeter. The bottom of the inner wall of the waste box 9 is provided with a slope that facilitates drainage. The slope facilitates the rapid discharge of waste liquid and reduces the residue of waste liquid in the waste box 9.

[0038] Reference Figure 2 A servo motor 15 is fixedly installed on the outside of the processing box 1. The output shaft of the servo motor 15 extends into the interior of the mounting groove 12 and is fixedly connected to the threaded rod 13. The rotation of the output shaft of the servo motor 15 can drive the rotation of the threaded rod 13.

[0039] Reference Figure 1 The outer side of the treatment box 1 is fixedly equipped with a controller, a hydraulic gauge and a pressure regulating valve. The outer side of the treatment box 1 is hinged with a rotating door, through which the replacement plate 16 inside the fixed plate 7 can be replaced.

[0040] Working principle: First, medical waste is placed into waste container 9. The controller simultaneously starts the servo motor 15 and the drive motor. The conveyor belt 2 travels at the same speed as the waste container 9. The rotation of the threaded rod 13 moves the threaded block 11, thus moving the waste container 9 and its contents into the processing box 1. The upper conveyor belt in the comparative patent is replaced with a fixed plate 7. When the waste container 9 reaches the middle of the processing box 1, the contact plates 8 on both sides of the waste container 9 remain in contact with the fixed plate 7, ensuring proper contact with the waste compressor head 18. Even after being squeezed, the waste container 9 remains stable, thus providing strong support to prevent breakage. Disinfectant is then sprayed into the waste container 9 through the nozzle, allowing it to come into contact with the medical waste. The waste compressor 18 compresses the medical waste in the waste container 9, achieving solid-liquid separation. The separated waste liquid falls into the drain platform 22 through the drain hole 17 in the replacement plate 16, and then flows into the corresponding waste liquid bottle 4. The waste liquid is collected and treated in a unified manner through the waste liquid bottle 4.

[0041] The embedded bolts 20 and embedded mounting blocks 21 facilitate the replacement and installation of damaged replacement plates 16. Since replacement plates 16 and drain holes 17 are in long-term contact with corrosive substances in waste liquid, replacing replacement plates 16 avoids the need to replace the entire device due to corrosion of some components, thereby reducing costs while ensuring the drainage effect of drain holes 17. Furthermore, the hydraulic gauge, pressure regulating valve, disinfection tank 5, and waste compressor 18 in this device are based on the same principle as a multifunctional medical waste sorting and treatment device with Chinese Patent Publication No. CN108339837B, and belong to the prior art, so further details are unnecessary.

[0042] The above are merely preferred embodiments of this application and are not intended to limit this application. Although this application 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 this application should be included within the protection scope of this application.
