Description

Technical Field

[0001] This invention relates to the technical field of medical waste treatment, and in particular to a hopper transfer device. Background Technology

[0002] The existing medical waste disposal modular unit is based on high-temperature steam sterilization technology and mainly consists of a high-temperature steam sterilization treatment system, a secondary pollution control system, and an automated control system. The sterilization treatment system includes units such as steam supply, feeding and transfer, high-temperature sterilization, and crushing. It uses two independent sterilization carts and three transfer platforms to realize the transfer of medical waste. After sterilization, the medical waste is poured into the crusher by an elevator, and after crushing, it is directly collected and transferred.

[0003] The equipment for transporting medical waste includes a hopper for holding medical waste and a transport vehicle located below the hopper to support it. The hopper and the transport vehicle are detachable. The empty hopper is placed inside the high-temperature steam sterilization equipment. The medical waste that has been sterilized by high-temperature steam is placed in the hopper. Then, the hopper is manually placed on the transport vehicle and moved to the crushing equipment. The medical waste in the hopper is poured into the feed inlet of the crushing equipment to complete the crushing.

[0004] However, since the side walls and bottom of the hopper are equipped with drainage holes, the high-temperature disinfectant water formed by the condensation of the high-temperature disinfection steam on the surface of the medical waste will drip onto the outside of the hopper through the drainage holes. Operators will inevitably be splashed during the transfer of the hopper, which will affect the safety of the operators and increase the risk of infection and high-temperature burns during the transfer process.

[0005] In view of this, the present invention is proposed. Summary of the Invention

[0006] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a hopper transfer device. By setting an assembly structure and a translation structure on the weighing platform, the hopper coming out of the sterilization equipment can be transferred to the crushing equipment without the need for manual operation by the operator. This reduces the number of times the operator comes into contact with medical waste during the transfer of medical waste, and reduces the risk of infection and high temperature burns to the operator during the transfer process.

[0007] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by the present invention is as follows: The present invention provides a hopper transfer device, comprising: a liftable weighing platform, one end of which is the entry end of the hopper into the weighing platform along its length. An assembly structure, located on a weighing platform, is used to drag the hopper from the inlet end of the weighing platform to the weighing platform. The translation structure, which is connected to the assembly structure, is used to move the assembly structure toward or away from the entry end of the weighing platform.

[0008] Furthermore, the weighing platform includes two first crossbeams extending along the length of the weighing platform; The translation structure includes a translation carriage, which is suspended and slidably mounted on two first crossbeams; The assembly structure includes an assembly bracket, which is located outside the two first crossbeams and slidably mounted on the first crossbeams. The assembly bracket is fixedly connected to the translational slide.

[0009] Furthermore, the assembly bracket has a sliding part and a support part that are distributed vertically on one side facing the first crossbeam; The sliding part is slidably mounted on the first crossbeam; The side of the translation carriage closest to the entry end of the weighing platform is fixed to the support.

[0010] Furthermore, a second crossbeam parallel to the first crossbeam is provided on one side of the first crossbeam; The side of the translation carriage away from the entrance of the weighing platform is slidably mounted on the second crossbeam via a sliding component; The first driving component is connected to the sliding component.

[0011] Furthermore, the sliding component has a plate-like structure and is groove-shaped; The sliding component is fastened to the second crossbeam with its slot facing downwards; The end of one sidewall of the sliding member protrudes outward from the groove to form a first fixing part that fits against and is fixedly connected to the bottom of the translational slide; The other sidewall of the sliding member protrudes outward from the groove to form a second fixing part that is fixedly connected to the first driving member.

[0012] Furthermore, an assembly gear set is rotatably provided on the side of the assembly bracket facing away from the first crossbeam. A second drive unit is located below the translation carriage; The bottom assembly gear in the gear assembly is connected to the second drive unit, while the top assembly gear is used to mesh with the rack on the hopper.

[0013] Furthermore, a docking support is provided on the side of the translation carriage facing the entry end of the weighing platform; The docking support has a docking flange on the side facing away from the translation slide; The connecting flange has connecting rods on both sides along the width direction of the weighing platform; The centerline of the connecting flange and the connecting rod extend along the length of the weighing platform.

[0014] Furthermore, a receiving slide bar that slides in conjunction with the hopper is provided above the second crossbeam; The top of the receiving slide bar is equipped with a limiting guide rail that extends along the length of the weighing platform and is slidably connected to the guide wheel assembly on the hopper.

[0015] Furthermore, the other end of the weighing platform itself along its length is the outlet end where the hopper leaves the weighing platform; The weighing platform is equipped with a first control component for controlling the opening of the hopper door and a second control component for controlling the movement of the push plate inside the hopper in the direction close to the door.

[0016] Furthermore, the first control component includes a first bracket disposed on the outside of the weighing platform and above the limit guide rail, and a first insert rod disposed on the top of the first bracket; The first insertion rod has an insertion hole at the end facing the weighing platform entrance, which is used for the control slide rod that passes through the side wall of the feeding hopper to slide and insert. Preferably, the second control component includes a second bracket located outside the weighing platform and above the limit guide rail, as well as a control motor and an electromagnetic clutch located on the second bracket; The output shaft of the control motor is connected to an electromagnetic clutch for docking with the flange of the hopper.

[0017] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art: The lifting support controls the docking structure to be horizontally aligned with the interface of the sterilization equipment. The translation structure moves the docking and assembly structures closer to the sterilization equipment until the docking structure contacts and connects to the sterilization equipment. Then, the assembly structure moves the hopper at the discharge port horizontally to the weighing platform. The docking structure then disconnects from the sterilization equipment. The translation structure moves the docking and assembly structures away from the sterilization equipment. The assembly structure then moves the hopper towards the control structure until it contacts the control structure. The control structure automatically pours the medical waste in the hopper into the feed inlet of the crushing equipment. The entire process does not require operators to approach the hopper and weighing platform, thereby reducing the number of times operators come into contact with medical waste during transportation and lowering the risk of infection and burns during transportation.

Detailed Implementation Example 1

[0020] like Figures 1 to 4As shown, the present invention provides a hopper transfer device, including a lifting support 400, a weighing platform 500, a docking structure 800, an assembly structure 600, a translation structure 700, and a control structure 900.

[0021] The weighing platform 500 has two ends along its length, one for the hopper to enter and the other for the hopper to exit. The entry end of the weighing platform 500 faces the discharge port of the sterilization equipment, and the exit end faces the inlet of the crushing equipment. The sterilization equipment moves the hopper carrying the sterilized medical waste to the discharge port. Because the discharge port of the sterilization equipment and the inlet of the crushing equipment are at different heights, a lifting bracket 400 is needed to adjust the height of the weighing platform 500 to accommodate the different equipment. This setup allows for automatic transfer of medical waste to the crushing equipment without operator intervention, reducing the number of times operators come into contact with the medical waste during transport and lowering the risk of infection and burns.

[0022] The docking structure 800 is located on the side of the weighing platform 500 facing the sterilization equipment and is used for horizontal docking with the discharge port of the sterilization equipment. The assembly structure 600 is used to move the hopper from the discharge port of the sterilization equipment onto the weighing platform 500. The translation structure 700 is installed on the weighing platform 500 and connects the assembly structure 600 and the docking structure 800. The translation structure 700 is used to move the assembly structure 600 and the docking structure 800 together closer to or further away from the sterilization equipment. The control structure 900 is located on the side of the weighing platform 500 facing the crushing equipment. The control structure 900 is used to control the automatic dumping of medical waste in the hopper to the feed inlet of the crusher.

[0023] Furthermore, the weighing platform 500 includes two first crossbeams 510 extending along the length of the weighing platform 500; The translation structure 700 includes a translation slide 710, which is suspended and slidably mounted on two first crossbeams 510; The assembly structure 600 includes an assembly bracket 610, which is located outside the two first crossbeams 510 and is slidably mounted on the first crossbeams 510. The assembly bracket 610 is fixedly connected to the translation slide 710.

[0024] There are two assembly brackets 610, which slide on the corresponding first crossbeams 510 respectively. The area between the two first crossbeams 510 is the inner area, and the two assembly brackets 610 are outside the two first crossbeams 510. Specifically, an auxiliary crossbeam parallel to the first crossbeam 510 is supported above the first crossbeam 510, and the assembly brackets 610 slide on the auxiliary crossbeam. The translational slide 710 is connected to the first crossbeam 510 via a first slider and slides along the length of the load-bearing platform 500 on the first crossbeam 510. The first slider is groove-shaped and is fastened to the first crossbeam 510 with the groove opening facing upwards. The translational slide 710 is fixedly connected to the bottom wall of the groove of the first slider. Figure 1 As shown, the length of the load-bearing platform 500 is in the left-right direction; The assembly bracket 610 is connected to the auxiliary crossbeam via the second slider and slides on the auxiliary crossbeam along the length of the weighing platform 500. The second slider is groove-shaped and is fastened to the auxiliary crossbeam with the groove facing downward. The arrangement of the first slider and the second slider improves the stability and smoothness of the sliding of the translation slide 710 and the assembly bracket 610.

[0025] Furthermore, the assembly bracket 610 has a sliding part 620 and a support part 630 that are distributed vertically on one side facing the first crossbeam 510. The sliding part 620 is slidably disposed on the first crossbeam 510; The side of the translation slide 710 near the entry end of the weighing platform 500 is fixed to the support part 630.

[0026] The sliding part 620 is provided on the bottom wall of the groove that supports and is fixed to the second slider; the translation slide 710 is clamped between the first slider and the support part 630, which increases the stability of the movement of the translation slide 710 and the assembly bracket 610.

[0027] Furthermore, a second crossbeam 520 parallel to the first crossbeam 510 is provided on one side; The side of the translation slide 710 away from the weighing platform 500 is slidably mounted on the second crossbeam 520 via the sliding member 720; A first driving component 750 is connected to the sliding component 720. The first driving component 750 is a servo electric cylinder 7501. The servo electric cylinder 7501 is fixed on the weighing platform 500.

[0028] The second crossbeam 520 is positioned higher than the first crossbeam 510, and the two first crossbeams 510 are located between the two second crossbeams 520; The sliding member 720 enables a sliding connection between the translational carriage 710 and the second crossbeam 520; specifically, the sliding member 720 has a plate-like structure and is groove-shaped. The sliding member 720 is fastened to the second crossbeam 520 with the slot facing downwards; The end of one sidewall of the sliding member 720 protrudes outward from the groove to form a first fixing part 730 that fits against and is fixedly connected to the bottom of the translational slide 710; The other sidewall of the sliding member 720 protrudes outward to form a second fixing part 740 that is fixedly connected to the first driving member 750.

[0029] The slider 720 slides on the second crossbeam 520 via the third slider, which is groove-shaped and engages with the second crossbeam 520 with the groove facing downwards; specifically, the slider 720 engages with the third slider with the groove facing downwards. The servo electric cylinder 7501 extends along the length of the weighing platform 500. The servo electric cylinder 7501 is located outside the two second crossbeams 520, and the output end of the servo electric cylinder 7501 is fixedly connected to the second fixing part 740.

[0030] The assembly structure 600 also includes an assembly gear set 640 and a second drive component 650;

[0031] Two sets of assembly gear groups 640 are provided, each corresponding to a group of brackets. The assembly gear group 640 includes several vertically meshing assembly gears. The assembly gears rotate along the length of the weighing platform. The assembly gear at the bottom is connected to the second drive unit 650, which is used to control the rotation of the assembly gear. The assembly gear at the top meshes with the rack 6 at the bottom of the hopper.

[0032] Additionally, a second drive unit 650 is mounted at the bottom of the translation slide 710. The second drive unit 650 includes a servo motor 6501, a reducer, and a universal joint coupling connected in sequence. The output end of the universal joint coupling is connected to the lowest assembled gear. The servo motor 6501 drives the assembled gear to rotate, thereby moving the hopper onto the weighing platform 500 through meshing with the rack 8 of the hopper. Multiple sets of assembled gears 640 can be connected simultaneously via the universal joint coupling.

[0033] The docking structure 800 includes a docking support 810, a docking rod 830, and a docking flange 820.

[0034] The docking support 810 is installed on the side of the translation slide 710 facing the entry end of the weighing platform 500, that is, the side of the translation slide 710 facing the discharge port of the sterilization equipment. The docking rod 830 is installed on the docking support 810 and is used to insert into the docking hole on the sterilization equipment. The docking flange 820 is installed on the docking support 810 and is used to connect with the electromagnetic clutch 9203 on the sterilization equipment.

[0035] When the servo electric cylinder 7501 drives the translation slide 710 to approach the inlet of the weighing platform, that is, when it approaches the outlet of the sterilization equipment, the docking rod 830 first gradually inserts into the docking hole of the sterilization equipment, and finally the docking flange 820 connects with the electromagnetic clutch 9203 on the sterilization equipment. The electromagnetic clutch 9203 can keep the connection between the translation slide 710 and the sterilization equipment stable and uninterrupted, ensuring a stable connection environment for the meshing transmission of the gears and the rack of the hopper in the subsequent assembly.

[0036] After the hopper moves to the weighing platform 500, the docking flange 820 and the electromagnetic clutch 9203 are disconnected. The drive assembly gear rotates until the hopper reaches a position approximately 100 mm away from the control structure 900. After the assembly gear stops rotating, the lifting bracket 400 is first raised to the discharge height, and then the servo electric cylinder 7501 retracts, driving the translation slide 710 to reset, thereby driving the hopper to move to the control structure 900. The flange on the hopper docks with the electromagnetic clutch 9203, and at the same time, the control slide rod 553 slides into the insertion hole 9103. The hopper door 2 is automatically opened under the drive of the connecting rod. After the door 2 is opened, the push plate 3 inside the hopper dumps the medical waste.

[0037] To ensure smoother movement of the hopper on the weighing platform 500, a receiving slide rod 530 is installed on the top of the weighing platform 500, which slides horizontally with the bottom of the hopper. A limiting guide rail 540, arranged along the length of the weighing platform 500, is located on the top of the receiving slide rod 530. A guide wheel assembly 9 is slidably connected within the limiting guide rail 540. Multiple sets of guide wheels are installed on the side wall of the hopper basket 1 and spaced apart along the length of the hopper. The end of the limiting guide rail 540 facing the sterilization equipment is closed, thereby limiting the sliding distance of the hopper.

[0038] The guide wheel assembly 9 includes rollers 91 and guide arc blocks 92. The rollers 91 are vertically arranged and rotatably mounted on the hopper basket 1. The guide arc blocks 92 are mounted on the hopper basket 1, and the end face facing away from the hopper basket 1 is an outwardly convex arc surface. Multiple sets of roller assemblies are arranged at intervals along their own trajectory within the limiting guide rail 540. Each roller assembly includes two rollers arranged in parallel and rotating. The arc surface of the guide arc block 92 slides against the peripheral wall of the roller.

[0039] As the hopper enters the weighing platform 500, its bottom end rolls on the receiving slide bar 530. The guide block 92 and roller 91 both enter the limiting guide rail 540. The roller 91 reduces the friction between the hopper and the receiving slide bar 530. The guide block 92 contacts the peripheral wall of the roller as it moves, causing the roller to roll. This further reduces friction with the hopper while completing the limiting guidance, thus lowering the load on the drive assembly gear and rack. The control structure 900 includes a first control element 910 for controlling the opening of the hopper's door panel and a second control element 920 for controlling the movement of the push plate inside the hopper towards the door panel. The first control element 910 is located on the side of the second control element 920 closest to the assembly structure 600.

[0040] First, the door panel is opened by the first control component 910, and then the push plate 3 inside the hopper is moved along the direction close to the door panel 2 by the second control component 920, thereby pushing the medical waste away from the hopper. The door panel is directly facing the feed inlet of the crushing equipment, thus completing the dumping of the medical waste.

[0041] The first control component 910 includes a first bracket 9101 and a first insertion rod 9102. The first bracket 9101 is installed on the weighing platform 500 and the first insertion rod 9102 is installed on the first bracket 9101. The first insertion rod 9102 has an insertion hole 9103 at one end facing the entry end of the weighing platform 500 for horizontally moving and inserting a control slide rod 553 that passes through the side wall of the feeding hopper. The first bracket 9101 is located outside the weighing platform 500 and is positioned higher than the limit guide rail 540. The movement of the inner push plate of the hopper is controlled by a control slide rod 553 extending from the side wall of the hopper. When the control slide rod 553 slides away from the door panel, the door panel opens. As the hopper approaches the first control member 910, the control slide rod 553 on the hopper slides into the insertion hole 9103 and abuts against the wall of the insertion hole 9103. As the hopper continues to move, the control slide rod slides away from the door panel relative to the hopper, and the door panel opens until the hopper moves to abut against the closed end of the limit guide rail 540.

[0042] Additionally, the second control component 920 includes a second bracket 9201, a control motor 9202, and an electromagnetic clutch 9203. The second bracket 9201 is mounted on the weighing platform 500, the control motor 9202 is mounted on the second bracket 9201 and its output shaft is connected to the electromagnetic clutch 9203. The electromagnetic clutch 9203 is used to dock with the flange on the linear guide rail of the hopper. The second bracket 9201 is located outside the weighing platform 500 and is positioned higher than the limit slide rail. The electromagnetic clutch 9203 contacts the flange, which is connected to the synchronous pulley via a drive shaft. The synchronous pulley is mounted on the four corner columns of the hopper. Under the operation of the motor 9202, the synchronous belt drives the push plate 3 to move closer to the door plate 2, so as to push the medical waste into the feed inlet of the crushing equipment.

[0043] Before medical waste is pushed out of the hopper and before the hopper enters the weighing platform, the lifting support 400 needs to adjust the height of the weighing platform 500. To know the weight of the medical waste in the hopper, a weighing sensor can be installed between the weighing platform 500 and the lifting support 400 to record the weight of the medical waste each time it is crushed.

[0044] The implementation principle of the hopper transfer device in this embodiment of the invention is as follows: When the sterilization equipment transports the hopper carrying medical waste to the discharge port, the lifting bracket 400 controls the docking structure 800 to be horizontally aligned with the docking interface facing the sterilization equipment. The translation structure 700 drives the docking structure 800 and the assembly structure 600 to approach the sterilization equipment together until the docking structure 800 contacts and connects to the sterilization equipment. Then, the assembly structure 600 drives the hopper located at the discharge port to move horizontally to the weighing platform 500. Subsequently, the docking structure 800 disconnects from the sterilization equipment, and the translation structure 700 controls the docking structure 800 and the assembly structure 600 to move away from the sterilization equipment. Afterward, the assembly structure 600 continues to drive the hopper to move towards the control structure 900 until it contacts the control structure 900. The control structure 900 controls the medical waste in the hopper to be automatically poured into the feed port of the crushing equipment. The entire process does not require operators to approach the hopper and the weighing platform, thereby reducing the number of times operators come into contact with medical waste during medical waste transfer and reducing the risk of infection and high-temperature burns to operators during the transfer process. Example 2

[0045] like Figures 5 to 11 As shown, the present invention provides a hopper structure, including an upward-opening hopper basket 1, a door panel 2, and a pusher plate 3.

[0046] The hopper 1 includes an outer support frame 11 and an inner liner 12. Multiple drainage holes 4, penetrating the inside and outside of the hopper 1, are spaced apart on the bottom and side walls of the inner liner 12. A discharge port 13 is provided on one side of the hopper 1 along its length. A hinge connects the top of the door panel 2 and the support frame 11 located at the top of the discharge port 13, allowing the door panel 2 to rotate upwards or downwards to cover the discharge port 13. An opening and closing assembly 5 is provided between the hopper 1 and the door panel 2 to control the upward or downward rotation of the door panel 2. A pusher plate 3 is located inside the cavity of the inner liner 12, with its periphery adapted to fit against the inner wall of the inner liner 12. A pushing assembly 6 is provided between the hopper 1 and the pusher plate 3 to control the sliding of the pusher plate 3 along the length of the hopper 1.

[0047] When medical waste is placed in the hopper 1, the door panel 2 is closed, and the push plate 3 abuts against the side wall of the inner liner 12 opposite the door panel 2. The medical waste is located between the door panel 2 and the push plate 3. The drainage hole 4 not only allows the water accumulated in the medical waste to flow to the outside of the hopper, but also accelerates the cooling of the medical waste. The opening and closing assembly 5 controls the door panel 2 to flip upward and open the discharge port 13. The pushing assembly 6 controls the push plate 3 to move closer to the door panel 2, thereby pushing the medical waste away from the discharge port 13 from the hopper 1.

[0048] In addition, since medical waste tends to stick to the inner liner 12 under high temperatures, a high-temperature resistant anti-stick layer 7 is provided on the inner liner 12, push plate 3, and door panel 2 to improve this situation. The high-temperature resistant anti-stick layer 7 is preferably made of polytetrafluoroethylene, which is resistant to high temperatures and has a low coefficient of friction. The high-temperature resistant anti-stick layer 7 prevents medical waste from sticking to the inner liner 12, and the drain hole 4 penetrates through the high-temperature resistant anti-stick layer 7, so the drainage of accumulated water is not affected.

[0049] The combination of drainage hole 4 and high-temperature resistant non-stick layer 7 reduces the number of times operators come into contact with medical waste when moving and dumping it, thereby reducing the risk of infection and high-temperature burns to operators during the transportation of medical waste.

[0050] To further guide the condensate accumulated in the inner liner 12 out of the liner 12, the bottom of the inner liner 12 is a downwardly curved drainage arc surface 14, and a row of spaced drainage holes is provided at the lowest point of the bottom of the inner liner 12 along the length of the basket 1. The bottoms of the door panel 2 and the push plate 3 are adapted to the bottom of the inner liner 12 to prevent medical waste from leaking from the door panel 2 or from being missed when the push plate 3 pushes the medical waste.

[0051] The feeding assembly 6 includes a linear guide rail 61, a connector 62, and a guide member 63.

[0052] In this embodiment, linear guide rails 61 are installed on the support frame 11 and multiple sets are arranged on both sides of the push plate 3 along the width direction of the bucket 1. The linear guide rails 61 are arranged along the length direction of the bucket 1 and one end is connected to the power source. In this embodiment, four linear guide rails 61 are provided, and the four linear guide rails 61 are arranged in pairs on both sides of the push plate 3 along the width direction of the bucket 1. The two linear guide rails 61 in the same group are arranged vertically, and the lower linear guide rail 61 is connected to the power source. Connecting the push plate 3 to the four linear guide rails 61 improves the stability of the push plate 3 during its movement.
