Technical Field

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

[0002] Medical activities generate a large amount of hazardous waste containing a combination of metal and plastic (such as metal needles and plastic syringes from disposable syringes, metal interfaces and plastic tubing from infusion sets, and metal parts and plastic handles from surgical instruments). This type of medical hazardous waste is classified as hazardous waste because it may be contaminated with pathogens, drug residues, or chemical pollutants, and must be treated in strict accordance with environmental protection and public health standards.

[0003] Traditionally, the treatment of medical waste containing metal in plastics involves manual sorting and the use of tools to separate the plastic from the metal. However, manual separation of metal-containing waste is difficult, cumbersome, and inefficient. In addition, manual handling can easily cause punctures from sharp metals (such as needles) or pose a risk of infection due to exposure to pathogens, thus posing certain safety hazards.

[0004] Therefore, it is necessary to provide a new medical hazardous waste treatment device to solve the above-mentioned technical problems. Utility Model Content

A bucket cover is fixedly installed on the upper end of the separation bucket, and a feed inlet is opened on the bucket cover. An exhaust pipe is fixedly installed on the bucket cover. A material rack is also fixedly installed inside the separation bucket.

[0007] The separation barrel is equipped with an electrothermal separation structure, which includes two cylindrical bodies distributed vertically. A large-diameter electric heating mesh and a small-diameter electric heating mesh are fixedly installed at the bottom of the two cylindrical bodies, respectively. A rotating shaft connected to the separation barrel is fixedly installed on each of the two cylindrical bodies.

[0008] A rotating frame is installed on the base, and multiple receiving cylinders are slidably connected to the base. The multiple receiving cylinders are distributed around the rotation center of the rotating frame, and one of the receiving cylinders is located directly below the separation barrel and closes the opening below the separation barrel.

[0009] Preferably, the support frame includes a fixing ring fixedly sleeved on the separation barrel, and multiple support rods are fixedly installed on the fixing ring. The multiple support rods are all L-shaped and fixedly connected to the base.

[0016] Compared with related technologies, the medical hazardous waste treatment device provided by this utility model has the following beneficial effects:

[0017] This invention employs a graded screening and layered heating method, using large and small diameter electric heating grids to classify and process solid waste of different particle sizes. This avoids uneven heating caused by particle differences, ensuring complete melting and separation of plastics with a low metal residue rate. The externally designed receiving cylinder allows for direct collection after cooling, simplifying subsequent processing steps and reducing the risk of human contact. Furthermore, multiple receiving cylinders are used alternately in a cyclical manner, reducing equipment downtime and increasing throughput.

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0027] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0028] Please see Figures 1 to 7 This utility model provides a medical hazardous waste treatment device, which includes: a base 1, with a foot 11 fixedly installed at the bottom of the base 1. The height of the foot 11 is greater than the length of the rotary motor 73. The base 1 is used for the installation of the device. The foot 11 raises the base 1, making it convenient for staff to collect and process the separated waste on the base 1. At the same time, it suspends the rotary motor 73 on the rotating frame 7 and protects it.

[0029] In the embodiments of this utility model, please refer to Figures 1 to 7 A support frame 4 and a separation tank 2 are installed on the base 1, with the separation tank 2 suspended on the base 1 via the support frame 4. A tank cover 3 is fixedly installed on the upper end of the separation tank 2, and a feed inlet 31 is opened on the tank cover 3. An exhaust pipe 32 is fixedly installed on the tank cover 3. A bulk material rack 8 is also fixedly installed inside the separation tank 2. The bulk material rack 8 includes a bulk material column 81, on which multiple arc-shaped bulk material rods 82 are fixedly installed, and the multiple arc-shaped bulk material rods 82 are all fixedly connected to the inner wall of the separation tank 2. The bulk material column 81 is located directly below the feed inlet 31. The tank cover 3 seals the upper end of the separation tank 2, and the feed inlet 31 is used for solid waste containing metal. The inlet 31 can be connected to external metal-containing solid waste conveying equipment for direct conveying of metal-containing solid waste. The exhaust pipe 32 discharges the gas generated during the electrothermal separation of metal-containing solid waste. To prevent the gas from containing harmful substances that may affect the environment, the exhaust pipe 32 can be connected to external waste gas treatment equipment to treat the discharged gas in a harmless manner before it is discharged. When the metal-containing solid waste enters the separation tank 2, it falls onto the bulk material rack 8 and is dispersed by the bulk material column 81 and the arc-shaped bulk material rod 82, so that it falls relatively evenly onto the electrothermal separation structure 5 for electrothermal separation treatment.

[0030] The support frame 4 includes a fixing ring 41 fixedly sleeved on the separation barrel 2, and multiple support rods 42 are fixedly installed on the fixing ring 41. The multiple support rods 42 are all L-shaped and fixedly connected to the base 1. The separation barrel 2 is suspended in the air by the support rods 42 and the fixing ring 41. The L-shaped support rods 42 can support the separation barrel 2 while avoiding affecting the normal use of the receiving barrel 6.

[0031] The separation tank 2 is also fixedly equipped with an upper guide plate 21 and a lower guide plate 22. The upper guide plate 21 is close to the upper end of the separation tank 2 and located below the arc-shaped material distribution bar 82, while the lower guide plate 22 is close to the lower opening of the separation tank 2. The upper guide plate 21 and the lower guide plate 22 guide the metal-containing solid waste to fall into the cylinder 51 for heating and separation, and then facilitate the collection of plastic and metal solid waste into the receiving cylinder 6 below.

[0032] To ensure the airtightness between the separation tank 2 and its bottom receiving cylinder 6, a ring-shaped high-temperature resistant sealing gasket 23 is also fixedly installed on the lower side wall of the separation tank 2; the high-temperature resistant sealing gasket 23 seals the gaps to prevent gas leakage.

[0033] To prevent metal-containing solid waste from getting stuck on the bulk material rack 8, the upper end of the bulk material column 81 has a hemispherical structure, and the cross-section of the arc-shaped bulk material rod 82 has a triangular structure; so that when the metal-containing solid waste falls onto the bulk material rack 8, it can slide down naturally.

[0034] The separation tank 2 is equipped with an electric heating separation structure 5, which includes two cylindrical bodies 51 distributed vertically. A large-diameter electric heating mesh 52 and a small-diameter electric heating mesh 53 are fixedly installed at the bottom of the two cylindrical bodies 51, respectively. A rotating shaft 54 ​​that is rotatably connected to the separation tank 2 is fixedly installed on each of the two cylindrical bodies 51. Two flip motors 55 are fixedly installed on the outer wall of the separation tank 2. The rotating shafts 54 on the two cylindrical bodies 51 are fixedly connected to the output ends of the two flip motors 55, respectively. A rotating frame 7 is installed on the base 1. Multiple receiving cylinders 6 are slidably connected to the base 1, and the multiple receiving cylinders 6 are distributed around the rotation center of the rotating frame 7. One of the receiving cylinders 6 is located directly below the separation tank 2 and closes the opening below the separation tank 2.

[0035] It should be noted that: Metal-containing solid waste enters the separation tank 2 through the feed inlet 31, and is dispersed into the upper cylinder 51 by the material distribution rack 8. Some smaller metal-containing solid waste particles fall through the large-diameter electric heating mesh 52 onto the lower small-diameter electric heating mesh 53. By energizing and heating the large-diameter and small-diameter electric heating mesh 52 and 53 respectively, the large and small metal-containing solid waste particles are heated separately. After the plastic is heated and melted, it drips through the large-diameter and small-diameter electric heating mesh 52 and 53 into the lower receiving cylinder 6 for collection. After a period of heating, the plastic melts completely and falls into the receiving cylinder 6. Only metal remains on the large-diameter heating wire mesh 52 and the small-diameter heating wire mesh 53. The rotating frame 7 controls the rotation of the receiving cylinder 6, and controls another empty receiving cylinder 6 to move directly below the separation tank 2. The tilting motor 55 controls the cylinder 51 to tilt through the rotating shaft 54, so that the remaining heated metal solid waste falls into the empty receiving cylinder 6 for collection. After the metal solid waste is collected, the tilting motor 55 controls the cylinder 51 to return to its original position. During the process of discharging the metal solid waste, the upper and lower parts need to be checked sequentially. The two cylinders 51 are flipped, i.e., the upper cylinder 51 is flipped first, and then the lower cylinder 51 is flipped, to avoid metal solid waste residue on the lower cylinder 51. The rotating frame 7 then controls another empty receiving cylinder 6 to connect with the lower end of the separation tank 2 for the next electrothermal treatment of metal-containing solid waste. The receiving cylinders 6 for receiving plastic and metal solid waste are all located on the outside, and can be directly collected after cooling. This utility model adopts a graded screening and layered heating method. Large and small diameter electric heating grids 53 are used to classify and process solid waste of different particle sizes, avoiding uneven heating caused by particle differences, ensuring that the plastic is fully melted and separated, and the metal residue rate is low. The external design of the receiving cylinders 6 allows for direct collection after cooling, simplifying subsequent processing steps and reducing the risk of human contact. At the same time, multiple receiving cylinders 6 are used alternately in a cycle, reducing equipment downtime and increasing processing capacity. Separation is achieved by utilizing the high-temperature melting characteristics of plastic, without the need to add chemical reagents, avoiding secondary pollution and meeting environmental protection requirements. During the high-temperature separation process, metal-containing solid waste can also be effectively disinfected at high temperature, reducing the risk of infection in subsequent processing.

[0036] The rotating frame 7 includes a rotating cylinder 71 rotatably connected to the base 1. Multiple annularly distributed connecting rods 72 are fixedly installed on the outer wall of the rotating cylinder 71. The multiple connecting rods 72 are fixedly connected to multiple receiving cylinders 6 respectively. A rotary motor 73 is fixedly installed on the lower side wall of the base 1. The rotating cylinder 71 is fixedly connected to the output end of the rotary motor 73. The rotary motor 73 controls the rotation of the rotating cylinder 71. The rotating cylinder 71 is fixedly connected to the receiving cylinders 6 through the connecting rods 72. The rotary motor 73 can control the multiple receiving cylinders 6 located on the base 1 to be used in a cyclic manner.

[0037] Furthermore, to protect the motor safety, a removable protective shell can be fitted over the flip motor 55 and the rotary motor 73 to increase their safety. To prevent gas leakage during the switching process of the receiving cylinder 6, an air pump can be installed on the exhaust pipe 32 to transport the gas to an external gas treatment device for harmless treatment. All motor connections use heat-insulating couplings to connect with the corresponding rotating shaft 54 ​​and rotating cylinder 71 to protect the motor. The bulk material rack 8 is difficult to process strip waste and needs to be able to crush the strip material. To prevent the electric heating grid from clogging, a vibrator can be installed at the bottom of the cylinder 6 to shake off impurities on the electric heating grid. At the same time, the vibrator needs to be heat-insulated.

[0038] The circuits and controls involved in this utility model are all existing technologies, and will not be described in detail here.

[0039] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
