Description

Technical Field

[0001] This utility model relates to the field of environmental protection technology, specifically to a dual-station medical waste feeding machine. Background Technology

[0002] Medical waste refers to waste generated by medical and health institutions during medical treatment, preventive healthcare, and other related activities that possess direct or indirect infectiousness, toxicity, or other hazards. Specifically, it includes infectious, pathological, damaging, pharmaceutical, and chemical waste. This waste contains large amounts of bacteria and viruses and exhibits characteristics of spatial pollution, acute viral transmission, and latent infectiousness. The harmfulness of its viruses and bacteria is tens, hundreds, or even thousands of times greater than that of ordinary household waste. Improper handling can cause serious environmental pollution and may even become a source of disease outbreaks.

[0003] High-temperature steam sterilization systems for medical waste use high-temperature steam to kill pathogenic microorganisms in medical waste, eliminating potential infectious hazards. During sterilization, medical waste needs to be transferred from the transfer container into a dedicated sterilization cart provided with the system. Most existing medical waste disposal systems rely on manual transfer, requiring dedicated operators to tilt and empty the medical waste transfer containers. Because medical waste carries large amounts of bacteria, viruses, or toxic substances, it is highly infectious, biotoxic, and corrosive. The close contact between personnel and medical waste during manual transfer poses significant safety hazards and infection risks. Utility Model Content

[0029] Please see Figure 1-7 A dual-station medical waste feeding machine includes a lifting mechanism sensor 2, a turnover box lifting mechanism 3, a first turnover box conveying mechanism 4, a first conveying mechanism sensor 5, a high-temperature sterilization cart 10, a hopper support 11, a main frame 17, a tilting and mounting frame 18, and a conveyor frame 19. A lifting motor 1 is located at the top of the main frame 17, and a conveyor frame 19 is located on the side of the main frame 17. A tilting and mounting frame 18 is located above the conveyor frame 19, and a second turnover box conveying mechanism 14 is located on the tilting and mounting frame 18. A tilting mechanism is located at the second turnover box conveying mechanism 14, which can tilt the turnover boxes. A second conveying mechanism sensor 15 is also located at the second turnover box conveying mechanism 14. The conveyor frame 19 has a turnover box conveying line 6, an empty box conveying line 7, and an inbound conveying line 8 from top to bottom, which can convey turnover boxes in different states.

[0030] The main frame 17 is equipped with a turnover box lifting mechanism 3. The turnover box lifting mechanism 3 is equipped with a lifting mechanism sensor 2, a first turnover box conveying mechanism 4 and a first conveying mechanism sensor 5. The lifting motor 1 can drive the turnover box lifting mechanism 3 to move up and down within the main frame 17. During the lifting process, the turnover box lifting mechanism 3 realizes the layer changing and positioning of the turnover box according to the feedback signal of the lifting mechanism sensor 2.

[0031] The lifting motor 1, lifting mechanism sensor 2, turnover box lifting mechanism 3, first turnover box conveying mechanism 4 and first conveying mechanism sensor 5 are assembled together to form a turnover box lifting system. The turnover box lifting system is responsible for adjusting the layer height of the turnover boxes. Specifically, it is responsible for adjusting the layer height of the turnover boxes as they enter the feeding system from the front end or after feeding, as they enter the back end processing equipment.

[0032] The first turnover box conveying mechanism 4 is located on the turnover box lifting mechanism 3, and the first turnover box conveying mechanism 4 has multiple sets from top to bottom. In this embodiment, the first turnover box conveying mechanism 4 has two sets. The first turnover box conveying mechanism 4 is responsible for the forward or backward movement of the turnover box inside the turnover box lifting system. The position of the turnover box is determined according to the first conveying mechanism sensor 5, and control signals are provided for the next action.

[0033] In this embodiment, the first turnover box conveying mechanism 4 uses a φ60mm double sprocket rubber-coated roller as the conveying carrier. The roller is made of SUS304 stainless steel, and the edge guard is made of SUS304 stainless steel plate by bending. The conveying power is a geared motor. The conveying roller can rotate forward or backward according to the needs of the waste treatment system. This enables the turnover box to enter the second turnover box conveying mechanism 14 from the first turnover box conveying mechanism 4 or to retreat from the second turnover box conveying mechanism 14 back to the first turnover box conveying mechanism 4.

[0034] The hopper support 11 is set on the side of the tilting installation frame 18. The bottom of the hopper support 11 is equipped with a sterilization cart conveyor line 9. A high-temperature sterilization cart 10 is located above the sterilization cart conveyor line 9. A dropping hopper 12 is located above the high-temperature sterilization cart 10. After the turnover box is tilted, the garbage inside can tilt and fall into the dropping hopper 12.

[0035] The second turnover box conveying mechanism 14 is responsible for the forward and backward movement of the turnover boxes within the tilting and mounting frame 18, and determines the position of the turnover boxes based on the feedback signal from the second conveying mechanism sensor 15. The second turnover box conveying mechanism 14 uses a φ60mm double sprocket rubber-coated roller as the conveying carrier. The roller body is made of SUS304 stainless steel, and the edge guards are made of bent SUS304 stainless steel plate. The conveying power is a geared motor; the conveying roller can rotate forward or backward as needed by the system.

[0036] Two sets of tilting mechanisms are arranged side by side, and two sets of corresponding tilting mechanisms are also provided for the turnover box lifting system.

[0037] The flipping mechanism includes a flipping frame 16, a flipping device 20, a first turnover box positioning mechanism 21, a second turnover box positioning mechanism 22, a flipping mechanism sensor 23, and a weighing device 24. The flipping device 20 controls the flipping of the flipping frame 16. The first turnover box positioning mechanism 21 and the second turnover box positioning mechanism 22 are mounted on the flipping frame 16 and can limit the turnover boxes entering the flipping frame 16. The flipping mechanism sensor 23 is mounted on the flipping mounting frame 18. The bottom of the flipping frame 16 is equipped with a weighing device 24, which can obtain the weight of the turnover boxes.

[0038] During use, after the turnover box reaches the predetermined position, the second turnover box conveying mechanism 14 stops running and the second turnover box positioning mechanism 22 is started. The second turnover box positioning mechanism 22 cooperates with the first turnover box positioning mechanism 21 to complete the clamping work of the turnover box, and then provides a positioning signal for the flipping mechanism to flip.

[0039] Assuming the horizontal state of the flipping mechanism is position a, a set of flipping mechanism sensors 23 are set; the state at which the preset flipping angle is reached is position b, and another set of flipping mechanism sensors 23 are set. When the other set of flipping mechanism sensors 23 detects the flipping mechanism, the flipping mechanism stops moving, thereby ensuring the flipping angle of the flipping mechanism.

[0040] The first turnover box positioning mechanism 21 is a fixed structure, ensuring the turnover box stays in the flipping frame 16. The second turnover box positioning mechanism 22 is a telescopic structure, which ensures close contact with the turnover box by pre-setting the cylinder extension length, and ensures that the turnover box is held tightly during the flipping process.

[0041] See Figures 3-7 During use, when the turnover box (open state) enters the flipping frame 16, a weight value T1 is obtained; when the flipping mechanism completes the flipping action and returns to the initial position, a weight value T2 is obtained. The T2 value is compared with the system's preset turnover box weight T. If the T2 value is within T value ±0.5kg, the turnover box is determined to have been successfully fed, and the turnover box returns to the turnover box lifting mechanism 3 via the second turnover box conveying mechanism 14. At the same time, the system will calculate the weight of medical waste in the box from the two weights: T2 - T1 = weight of medical waste in the box, and summarize the weight of medical waste fed in this operation.

[0042] A shock absorber 13 is provided on the side of the tilting frame 18 near the hopper 12. The shock absorber 13 can buffer the tilting frame 16 after it is tilted, reducing the impact damage to the tilting frame 16.

[0043] In this embodiment, the hopper support 11 and the discharge hopper 12 are welded from Q235-A carbon steel and the surface is powder-coated to improve the corrosion resistance of the entire device. The bottom of the discharge hopper 12 is also equipped with a liquid receiving tank to collect any liquid substances that may be present in medical waste, and to collect and treat them regularly to avoid pollution to the environment and equipment.

[0044] In use, the front-end conveying system delivers the turnover box (open state) to the conveyor frame 19, and then to the bottom entrance of the turnover box lifting mechanism 3. The first turnover box conveying mechanism 4 then transports the turnover box into the turnover box lifting mechanism 3. The first conveying mechanism sensor 5, based on feedback signals, determines that the turnover box (open state) is in position and starts the lifting motor 1. Then, based on feedback signals from the lifting mechanism sensor 2, the turnover box (open state) is stopped in front of the entrance of the second turnover box conveying mechanism 14.

[0045] When the back-end processing equipment is ready for feeding, the feeding system controls the first turnover box conveyor mechanism 4 and the second turnover box conveyor mechanism 14 to operate synchronously, sending the turnover box (open state) into the flipping frame 16. When the second conveyor mechanism sensor 15 detects the turnover box arrival signal, the first turnover box conveyor mechanism 4 and the second turnover box conveyor mechanism 14 stop operating.

[0046] After the second turnover box locking mechanism 22 clamps the turnover box (in the open state), the flipping device 20 is activated. Two sets of flipping mechanism sensors 23 determine the flipping angle of the turnover box. When the preset angle is reached, the flipping device 20 stops operating, and simultaneously, the flipping frame 16 makes contact with the bottom shock absorber 13. Utilizing the inertia upon stopping, the medical waste inside the turnover box detaches from the box and then falls through the hopper 12 into the high-temperature sterilization cart 10 below, completing the medical waste flipping and feeding process.

[0047] After the empty containers have finished unloading, they return to the lifting mechanism 3 via the second conveyor mechanism 14 and the first conveyor mechanism 4. Then, they are lowered to the empty container conveyor line 7 via the control program and transported to the end cleaning equipment. After cleaning at the cleaning equipment, the containers can be put into storage via the storage conveyor line 8.

[0048] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
