Description

Technical Field

[0001] This utility model relates to the field of conveying equipment, specifically to a feeding device for emergency incineration of medical waste. Background Technology

[0002] In the emergency incineration and disposal of medical waste, especially COVID-19-related medical waste, safe, efficient, and automated feeding is crucial for ensuring both disposal efficiency and personnel safety. The tilting elevator, as the core equipment of the feeding system, primarily functions to smoothly and accurately lift the special collection bins containing medical waste to the incinerator inlet height and complete the unloading and tilting action. The effectiveness of this device directly affects the continuity and automation level of the entire disposal process, and is of great significance for avoiding direct contact between personnel and waste, preventing secondary pollution, and improving emergency response capabilities.

[0003] Currently, existing tilting and lifting machines typically employ a frame structure and are equipped with a dedicated clamping device to secure the medical waste bins. Specifically, this clamping device is usually driven by a hydraulic or electric mechanism, which moves one or more pairs of clamping arms or claws to grip and hold the bin from the side or below. After the bin is transported to the unloading station by the vertical movement of the lifting mechanism, the tilting mechanism drives the entire clamping device, along with the bin, to rotate around an axis, thereby dumping the waste. To prevent the medical waste bins from falling off, a crossbeam is installed at the top of the clamping mechanism.

[0004] However, with the increasing volume of medical waste, the size of medical waste bins used is becoming increasingly larger in order to improve single-use efficiency. This trend has led to a corresponding increase in the structural dimensions of clamping devices designed to ensure gripping stability. During actual unloading and tipping, the outer edge of the large clamping device is prone to spatial interference and collision with the surrounding structure of the unloading port (such as the rim, sealing device, or support frame) when rotated to a specific angle. This structural interference may not only damage the equipment and interrupt the unloading process, affecting disposal efficiency, but also pose a safety hazard due to the collision. Secondly, the crossbeam above the clamping mechanism can hinder the complete tipping of the medical waste bin during tipping, resulting in waste residue. This not only causes incomplete disposal but may also lead to cross-contamination. Utility Model Content

[0005] The present invention aims to provide a feeding device for emergency incineration of medical waste, in order to solve the problem that the increased size of the clamping mechanism due to the increased size of the medical container leads to spatial interference and collision between the clamping mechanism and the surrounding structure of the discharge port during the flipping process.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A feeding device for emergency incineration of medical waste includes a shell and an internal conveying mechanism. The internal conveying mechanism is slidably installed inside the shell, and a lifting mechanism for raising the internal conveying mechanism is provided at the top of the shell. The internal conveying mechanism includes a lower limit position, a lifting section, a tilting section, and a return section during its movement. Clamping mechanisms are provided on the frames on both sides of the internal conveying mechanism. The clamping mechanism includes a base, a clamping part, and a limiting part. The base is installed on the frame, the clamping part is fixedly connected to the middle of the base, and the limiting part is slidably connected inside the base. The limiting part includes a pressure plate, a rotating rod, a guide rod, and an elastic element. The pressure plate is rotatably connected to the rotating rod, the bottom of the pressure plate is connected to one end of the guide rod, and both ends of the elastic element are fixedly connected to the other end of the guide rod and the internal conveying mechanism, respectively. Guide sleeves are provided on the outer periphery of the elastic element and the guide rod.

[0007] Beneficial effects: 1. The elastic element's resetting action drives the guide rod downwards, causing the pressure plate to apply a stable clamping force from the top of the material bin. This, combined with the clamping parts on both sides, forms a three-point clamping structure. This design ensures the material bin remains in a fixed position during the lifting, tilting, and return processes of the internal conveying mechanism, effectively preventing slippage or shaking and ensuring smooth and reliable operation. Furthermore, the pressure plate design eliminates the need for a crossbeam, preventing obstruction and snagging of waste materials. This ensures that waste materials inside the bin can be completely and cleanly dumped into the discharge port by gravity, fundamentally preventing residue and cross-contamination caused by incomplete dumping.

[0008] 2. The rotating connection design between the pressure plate and the rotating rod makes the clamping mechanism more compact and flexible while providing sufficient clamping force. When flipped to the vicinity of the discharge port, the mechanism can effectively avoid the risk of collision with surrounding equipment, fundamentally solving the structural interference problem caused by excessively large clamping device size or conflicting movement trajectories, and improving the continuity and safety of equipment operation.

[0009] Preferably, as an improvement, a limiting groove is provided on the guide rod, and a positioning pin is fixedly connected to one end of the guide rod near the pressure plate, the positioning pin passing through the limiting groove.

[0010] Beneficial effects: The design of the limiting groove provides a clear movement distance for the guide rod. Since the guide rod itself is to guide the pressure plate to move in a straight line and prevent it from tilting or getting stuck, the limiting groove and positioning pin can effectively prevent the guide rod from changing angle, which would lead to angle deviation of the pressure plate and insufficient clamping force of the pressure plate.

[0011] Preferably, as an improvement, the clamping part includes a clamping block and a fixing member. The clamping block is connected to the base through the fixing member, and both ends of the clamping block extend toward the base to form clearance openings.

[0012] Beneficial effects: The clearance openings at both ends of the clamping block form a "flared mouth," facilitating automatic centering of the material bin upon entry and providing sufficient encapsulation space during clamping, reducing the precision requirements for feeding and positioning and increasing feeding speed. Secondly, the clamping block, connected by fasteners, has a robust structure and can provide sufficient clamping force to secure heavier medical waste bins.

[0013] Preferably, as an improvement, the housing is provided with blocks on both sides of the feed inlet, and when the internal conveying mechanism is at the lower limit, the bottom of the rotating rod abuts against the block, pulling the guide rod, and the pressure plate is in a raised state.

[0014] Beneficial effects: By abutting the stop block and the rotating rod, it is ensured that the clamping plate of the clamping mechanism is automatically raised each time the inner conveying mechanism returns to the lower limit, preparing for receiving new material buckets; and the mechanism is reset by using the movement of the equipment itself (descending to the bottom), without the need for an additional power source or control signal. It is ingeniously designed, low in cost, and highly reliable.

[0015] Preferably, as an improvement, the shell forms a discharge port at the tilting section, and columns are formed on both sides of the discharge port. The internal conveying mechanism swings the rotating rod and the pressure plate during the tilting section.

[0016] Beneficial effects: In the tilting section, the swinging of the rotating rod and the pressure plate drives the material bucket to tilt more than 90 degrees, ensuring that viscous or tightly packaged medical waste can be completely dumped under the action of gravity, avoiding residue.

[0017] Preferably, as an improvement, a linear guide rail and a tilting guide rail are arranged side by side inside the housing. The two ends of the linear guide rail abut against the top and bottom of the housing, respectively. The bottom of the tilting guide rail is fixedly connected to the bottom of the housing. The straight section of the tilting guide rail is parallel to the linear guide rail, and the bent section is located inside the discharge port of the housing. The end of the internal conveying mechanism near the lifting mechanism is connected to the linear mechanism, and the side of the base near the lifting mechanism is connected to the tilting guide rail through a slider.

[0018] Beneficial effects: The linear guide ensures the vertical lifting of the inner conveying mechanism, while the tilting guide guides the clamping mechanism to complete the tilting through its bent section. The two are arranged side-by-side, with decoupled motion and precise coordination; moreover, the guide system provides rigid support and precise guidance for the entire motion, preventing swaying, making it particularly suitable for heavy-load and frequently start-stop conditions.

[0019] Preferably, as an improvement, the lifting mechanism includes a chain and a lifting drive for driving the chain to move. The lifting drive is installed on the top of the housing, and a driven wheel is provided at the bottom of the housing. The chain is rotatably connected in the driven wheel, and the chain near the side of the flipping guide is located in the linear guide. The inner conveying mechanism is fixedly connected to the chain.

[0020] Beneficial effects: Chain drives have the advantages of high traction and strong load-bearing capacity, making them ideal for lifting heavy objects. Fixing the internal conveyor mechanism to the chain ensures direct transmission of lifting force and synchronization between both sides.

[0021] Preferably, as an improvement, the inner conveying mechanism includes an inner scale board machine and an inner drive unit for driving the inner scale board machine to rotate. The inner drive unit is installed at the bottom of the inner scale board machine, the frames on both sides of the inner scale board machine are fixedly connected to the chain, and the base is fixedly connected to the top of the inner scale board machine.

[0022] Beneficial effects: Using a slatted conveyor as the conveying medium results in a robust structure and a large bearing surface, making it ideal for conveying regular solid waste such as boxes and barrels. Furthermore, the internal drive components independently control the operation of the slatted conveyor, allowing for separation from lifting actions. For example, it can operate slowly when receiving material or briefly reverse during dumping to shake off waste, providing a more flexible control strategy.

[0023] Preferably, as an improvement, it also includes an external conveying mechanism, which is installed outside the housing and is used to convey materials from outside the housing to an internal conveying mechanism installed inside the housing.

[0024] Beneficial effects: The injection of the external conveying mechanism achieves seamless connection between the inside and outside of the shell, making the layout of the entire device more reasonable, the logistics smoother, and reducing manual operation links, thereby improving the overall processing efficiency.

Detailed Implementation

[0031] The following detailed description illustrates the specific implementation method: The basic implementation examples are as follows: Figures 1-5 As shown: like Figure 1 As shown, a feeding device for emergency incineration of medical waste includes a housing 1 and an inner conveying mechanism 2. The housing 1 has a feed inlet 13 at its bottom and a discharge outlet 14 at its top. The inner conveying mechanism 2 is slidably installed inside the housing 1. A lifting mechanism 3 for raising the inner conveying mechanism 2 is provided at the top of the housing 1. The inner conveying mechanism 2 includes a lower limit position, a lifting section, a tilting section, and a return section during its movement. Clamping mechanisms 4 are provided on the frames on both sides of the inner conveying mechanism 2. The lifting mechanism 3 includes a chain 31 and a lifting drive component 32 for driving the chain 31. The lifting drive component 32 is installed at the top of the housing 1. A driven wheel 33 is provided at the bottom of the housing 1. The chain 31 is rotatably connected to the driven wheel 33, and the chain 31 near the tilting guide rail 12 is located within a linear guide rail 11. The inner conveying mechanism 2 is fixedly connected to the chain 31.

[0032] Furthermore, the inner conveying mechanism 2 includes an inner scale board machine 21 and an inner drive component 22 for driving the inner scale board machine 21 to rotate. The inner drive component 22 is installed at the bottom of the inner scale board machine 21. The frames on both sides of the inner scale board machine 21 are fixedly connected to the chain 31, and the base 41 is fixedly connected to the top of the inner scale board machine 21.

[0033] Specifically, a linear guide rail 11 and a tilting guide rail 12 are arranged side by side inside the housing 1. The two ends of the linear guide rail 11 abut against the top and bottom of the housing 1, respectively. The bottom of the tilting guide rail 12 is fixedly connected to the bottom of the housing 1, and the straight section 121 of the tilting guide rail 12 is parallel to the linear guide rail 11. The bent section 122 is located inside the discharge port 14 of the housing 1. The end of the inner conveying mechanism 2 near the lifting mechanism 3 is connected to the linear mechanism. The side of the clamping mechanism 4 near the lifting mechanism 3 is connected to the tilting guide rail 12 via a slider 23. It is worth noting that when the lifting mechanism 3 pulls the inner conveying mechanism 2 and the clamping mechanism 4 up to the bent section 122, as... Figure 2As shown, the slider 23 on the clamping mechanism 4 moves along the bend, while the inner conveying mechanism 2 rises along the linear guide rail 11 along the chain 31, thereby realizing the overturning and tipping of the material bucket 6.

[0034] Furthermore, this embodiment also includes an external conveying mechanism 5, which is installed outside the housing 1 and is used to convey materials from outside the housing 1 to an internal conveying mechanism 2 installed inside the housing 1. Similar to the internal conveying mechanism 2, the external conveying mechanism 5 also includes a slatter machine and a drive component for driving the slatter machine to rotate.

[0035] like Figures 3-5 As shown, the clamping mechanism 4 includes a base 41, a clamping part 42, and a limiting part 43. The base 41 is mounted on the frame, the clamping part 42 is fixedly connected to the middle of the base 41, and the limiting part 43 is slidably connected inside the base 41. The clamping part 42 includes a pressing block 421 and a fixing member 422. The pressing block 421 is connected to the base 41 through the fixing member 422, and both ends of the pressing block 421 extend toward the base 41 to form clearance openings.

[0036] Furthermore, the limiting part 43 includes a pressure plate 431, a rotating rod 432, a guide rod 433, and an elastic element 434. The pressure plate 431 is rotatably connected to the rotating rod 432. The bottom of the pressure plate 431 is connected to one end of the guide rod 433. Both ends of the elastic element 434 are fixedly connected to the other end of the guide rod 433 and the inner conveying mechanism 2, respectively. Guide sleeves 435 are provided on the outer periphery of the elastic element 434 and the guide rod 433. A limiting groove 4351 is provided on the guide rod 433. A positioning pin 44 is fixedly connected to one end of the guide rod 433 near the pressure plate 431. The positioning pin 44 passes through the limiting groove 4351.

[0037] The housing 1 is provided with baffles 15 on both sides of the feed inlet 13. When the inner conveying mechanism 2 is at the lower limit, the bottom of the rotating rod 432 abuts against the baffle 15, and the guide rod 433 is pulled, and the pressure plate 431 is in a raised state.

[0038] The housing 1 forms a discharge port 14 at the tilting section, and columns are formed on both sides of the discharge port. The inner conveying mechanism 2 swings the rotating rod 432 and the pressure plate 431 during the tilting section.

[0039] In use, the operator first activates the external conveying mechanism 5 to smoothly transport the material bin 6 containing medical waste from the outside of the housing 1 to the internal conveying mechanism 2 inside the housing 1. When the material bin 6 is delivered to the surface of the scale plate of the internal conveying mechanism 2, the clamping block 421 of the clamping mechanism 4 clamps the bin body from both sides under the action of the fixing member 422. At this time, since the internal conveying mechanism 2 is at the lower limit position, the bottom of the rotating rod 432 abuts against the stop blocks 15 on both sides of the feed port 13 of the housing 1. The pressure plate 431 is in a raised state under the cooperation of the guide rod 433 and the elastic member 434, and the clearance provides sufficient space for the material bin 6 to enter.

[0040] As the lifting drive 32 is activated, the chain 31 begins to move under the constraint of the driven wheel 33 and the linear guide rail 11, driving the inner conveying mechanism 2 and clamping mechanism 4 fixed thereon to rise as a whole. During the lifting section, as the clamping mechanism 4 rises, the bottom of the rotating rod 432 separates from the stop block 15, and the pressure plate 431 of the clamping mechanism 4 continues to apply stable pressure to the material bucket 6 under the reset action of the elastic element 434, preventing it from shifting. When running to the tilting section, the slider 23 on the clamping mechanism 4 slides along the bend of the tilting guide rail 12, while the inner conveying mechanism 2 continues to rise vertically along the linear guide rail 11 under the traction of the chain 31. This relative movement forces the clamping mechanism 4 to tilt. Since the length of the rotating rod 432 and the pressure plate 431 exceeds the width of the discharge port 14, the rotating rod 432 can rotate relative to the plane of the pressure plate 431, avoiding interference between the rotating rod 432 and the column next to the discharge port 14 during the tilting process of the material bucket 6. The pressure plate 431 swings under the guidance of the limiting groove 4351 and the positioning pin 44 of the guide rod 433, pushing the material bucket 6 to flip synchronously with the clamping mechanism 4, and preventing the material bucket 6 from falling off after it has completely flipped over. At this time, the elastic element 434 applies a controllable buffering force to the guide rod 433 through the guide sleeve 435 to ensure that the material bucket 6 remains stable during the flipping process.

[0041] When the material bin 6 is tilted to the position directly above the discharge port 14, with the opening facing downwards, the medical waste falls into the subsequent treatment unit along the discharge port 14 of the shell 1 under the influence of gravity. After unloading, the lifting drive 32 reverses its rotation, and the chain 31 drives the inner conveying mechanism 2 and the clamping mechanism 4 to descend along the return section. When passing through the tilting section, the clamping mechanism 4 gradually returns to its original position under the action of the guide rail, at which point the column can push the rotating rod 432 to reset. When the inner conveying mechanism 2 returns to the lower limit position, the rotating rod 432 abuts against the stop block 15 again, and the pressure plate 431 returns to its initial raised state. The entire system resets, awaiting the next round of feeding operation.
