[0093] Existing technologies use crushing devices to pulverize medical waste. However, medical waste includes bottles such as medicine bottles and medical glassware, especially large-diameter infusion glass bottles. When using crushing rollers, these bottles may slip on the crushing rollers, resulting in poor pulverization.

[0094] In view of this, such as Figures 1 to 9 As shown, this solution provides a medical waste treatment device to alleviate the above-mentioned problems. The device includes a housing 100 and a central crushing roller 200, and includes a damage assessment mechanism and a crushing assembly disposed within the housing 100.

[0095] The damage assessment mechanism is equipped with two sets of edge crushing rollers 310 and two sets of end seats 320;

[0096] Two sets of edge crushing rollers 310 are respectively rotatably connected to a set of end seats 320 on a fixed axis;

[0097] The housing 100 is provided with a transverse sliding groove for the end seat 320 to slide in the horizontal direction;

[0098] The intermittent crushing assembly can control the side crushing rollers 310 to move synchronously towards or away from each other in the horizontal direction and to rotate freely in the vertical direction.

[0099] The housing 100 is also equipped with a linkage component that controls the synchronous rotation of the central crushing roller 200 and the side crushing roller 310;

[0100] A separator seat 120 is provided between the center crushing roller 200 and the side crushing roller 310;

[0101] The partition seat 120 is fixedly connected to the inner wall of the housing 100;

[0102] The divider 120 is equipped with a tilting component;

[0103] The tilting assembly can control the movement of glass bottles that are slipping on the central crushing roller 200 to the side crushing roller 310.

[0104] like Figure 1 and2 As shown, when processing medical waste, the medical waste is fed into the shell 100 through the feeding hopper. The medical waste falls between two sets of central crushing rollers 200. The medical waste is crushed by the central crushing rollers 200 that rotate freely in the vertical direction. The crushed medical waste falls into the collection area below the central crushing rollers 200 for subsequent drying or separation processing.

[0105] Meanwhile, when smooth cylindrical items such as medicines or infusion bottles in medical waste slip between the two central crushing rollers 200, the tilting assembly will drive the two sets of central crushing rollers 200 to deflect at a certain angle in the vertical direction. During the deflection process, the central crushing rollers 200 tilt towards the side crushing roller 310, causing the slipping medical waste to slide down to the side crushing roller 310 under the action of gravity.

[0106] Furthermore, two sets of edge crushing rollers 310 are respectively mounted on one set of end seats 320. Driven by the inter-crushing component, the two sets of end seats 320 and the edge crushing rollers 310 mounted thereon can move synchronously towards or away from each other in the horizontal direction. The edge crushing rollers 310 are always rotating during the horizontal movement, thereby crushing the medical waste on them by the two sets of edge crushing rollers 310 that rotate continuously and have a constant spacing.

[0107] During the operation of the edge crushing rollers 310, the distance between the two sets of edge crushing rollers 310 dynamically changes, thereby altering the force position and state of the medical waste between the edge crushing rollers 310, increasing the possibility of it being gripped, squeezed, and crushed. When the distance narrows, the clamping and crushing force on the medical waste increases, causing difficult-to-crush medical waste to break. When the distance widens, the position and orientation of the difficult-to-crush medical waste are changed, preventing it from continuously sliding on the surface of the edge crushing rollers 310. At the same time, the change in distance causes the difficult-to-crush medical waste to be subjected to intermittent squeezing, breaking the balance between the medical waste and the edge crushing rollers 310 during the sliding process, forcing the medical waste to shift and flip. The periodic change in distance, combined with the rotation of the edge crushing rollers 310, can generate shearing forces with continuously changing force directions, applying destructive forces to the medical waste in different directions, further reducing the slippage phenomenon, thereby ensuring that the bottle can be crushed to release the residual liquid waste inside.

[0108] In this design, the intermittent assembly includes a support frame 410, a splined shaft 420, and a worm gear 322;

[0109] The two ends of the spline shaft 420 are respectively rotatably connected to a support frame 410.

[0110] The splined shaft 420 can rotate freely in the vertical direction;

[0111] A worm gear 430 is fitted onto the splined shaft 420;

[0112] The end seat 320 is provided with a receiving groove 321 at the position corresponding to the worm gear 430;

[0113] There is a certain gap between the worm gear 430 and the receiving groove 321;

[0114] The worm gear 322 is mounted on the end seat 320 and is rotatably connected to the end seat 320 on a fixed axis.

[0115] The worm 430 is meshed with the worm wheel 322;

[0116] The worm gear 322 is coaxially and fixedly connected to the edge crushing roller 310;

[0117] A short connecting rod 323 is coaxially fixed on the side of the worm gear 322 away from the end seat 320;

[0118] A long connecting rod 324 is provided at the end of the short connecting rod 323 that is away from the worm gear 322;

[0119] Short link 323 is rotatably connected to long link 324;

[0120] The end of the long connecting rod 324 away from the short connecting rod 323 is rotatably connected to the support frame 410.

[0121] like Figures 1 to 4 As shown, a motor fixedly mounted on the housing 100 controls the continuous vertical rotation of the splined shaft 420 between the two sets of support frames 410. A worm gear 430 is fitted onto the housing 100, causing the worm gear 430 to rotate synchronously when the splined shaft 420 rotates. The worm gear 430 is meshed with a worm wheel 322, and the worm gear 430 is positioned within a receiving groove 321 on the worm wheel 322. Simultaneously, the worm wheel 322 rotates, causing a short connecting rod 323 coaxially mounted on it to rotate. A long connecting rod 324 that can freely deflect is provided between the short connecting rod 323 and the support frame 410. Therefore, when the splined shaft 420 rotates, the worm gear 430 and worm wheel 322 can drive the end seat 320 to reciprocate horizontally. Furthermore, the worm wheel 322 is coaxially fixed with the edge crushing roller 310, thereby driving the edge crushing roller 310 to continuously rotate vertically while following the horizontal reciprocating motion of the end seat 320.

[0122] It should be noted that the two ends of the long connecting rod 324 are fixed to the short connecting rod 323 and the support frame 410, respectively. The short connecting rod 323 rotates synchronously with the worm gear 322. Therefore, the long connecting rod 324 can deflect synchronously when the worm gear 322 rotates. Under the constraint of the long connecting rod 324, the horizontal position of the worm gear 322 changes back and forth in the horizontal direction when it rotates continuously. This drives the end seat 320 and the side crushing roller 310 to move back and forth in the horizontal direction. This, in turn, drives the distance between the two sets of side crushing rollers 310 to change continuously within a certain range, so as to prevent the bottle on it from continuously slipping. This ensures that the bottle can be crushed and the liquid waste inside can be released.

[0123] In this design, the end of the edge crushing roller 310 away from the end seat 320 is coaxially fixed with a first axial ball 330;

[0124] The partition seat 120 is provided with a transverse ball cavity 122 that is slidably connected to the first axis ball 330.

[0125] Specifically, a partition seat 120 is provided between the side crushing roller 310 and the center crushing roller 200. To ensure the stability of the side crushing roller 310 during rotation and horizontal movement, a transverse ball cavity 122 is provided on the partition seat 120 for sliding connection of the first axial ball 330. The first axial ball 330 is coaxially fixed with the side crushing roller 310. Therefore, the transverse ball cavity 122 can be used to form the first axial ball 330 and the side crushing roller 310, and the transverse ball cavity 122 can meet the rotational movement of the first axial ball 330, thereby ensuring the stability of the two sets of side crushing rollers 310 during movement.

[0126] In this solution, the linkage components include a directional alignment plate 111, a positioning plate 112, an L-shaped side plate 113, and a swing alignment plate 114;

[0127] The directional alignment disk 111 is disposed on the separator 120 and is rotatably connected to the separator 120 on a fixed axis;

[0128] The directional alignment disk 111 is connected to the splined shaft 420 via a transmission connection.

[0129] On the side of the directional colocation disk 111 away from the separator 120, there are multiple sets of active directional columns 115 arranged in a ring array;

[0130] Positioning plate 112 is fixedly connected to partition seat 120;

[0131] Positioning plate 112 is rotatably connected to L-shaped side plate 113 on a fixed axis;

[0132] The end of the L-shaped side plate 113 away from the positioning plate 112 is rotatably connected to the swing-alignment plate 114;

[0133] The swing-oriented plate 114 is fixed coaxially with the central crushing roller 200;

[0134] On the side of the swaying locator 114 near the directional locator 111, there are multiple sets of driven transmission columns 116 arranged in a ring array.

[0135] Multiple sets of active transmission columns 115 and driven transmission columns 116 are staggered and interleaved, and the connected active transmission columns 115 and driven transmission columns 116 are slidably connected.

[0136] like Figure 1 , 2 As shown in Figures 5 and 6, the directional alignment disk 111 is connected to the spline shaft 420 via a transmission connection. When the spline shaft 420 rotates, it can drive the directional alignment disk 111 and its multiple sets of active transmission columns 115 to rotate synchronously. The multiple sets of active transmission columns 115 and driven transmission columns 116 are staggered and have sliding contact with each other. Therefore, when the directional alignment disk 111 rotates, it can drive the swing alignment disk 114 to rotate synchronously in the vertical direction through the active transmission columns 115 and driven transmission columns 116.

[0137] Meanwhile, the swaying plate 114 and the central crushing roller 200 are coaxially arranged, so that when the splined shaft 420 drives the side crushing roller 310 to rotate through the inter-crushing assembly, it can drive the central crushing roller 200 to rotate synchronously. Furthermore, the swaying plate 114 is set on the L-shaped side plate 113, and the L-shaped side plate 113 and the positioning plate 112 fixedly set on the partition seat 120 rotate on a fixed axis. Thus, in actual use, the swaying assembly drives the L-shaped side plate 113 to deflect a certain angle in the vertical direction, thereby changing the tilt angle of the central crushing roller 200 in the horizontal direction.

[0138] Furthermore, when the horizontal inclination angle of the L-shaped side plate 113 and the central crushing roller 200 changes, the swing-aligning plate 114 and the driven transmission column 116 thereon deflect synchronously. The swing-aligning plate 114 can still rotate synchronously with the sizing plate through the driven transmission column 116 and the active transmission column 115. Thus, when the central crushing roller 200 deflects in the vertical direction, its slope foot can face one side of the side crushing roller 310. Under the trend of the linkage component, it can ensure that the central crushing roller 200 always maintains a rotating state, thereby ensuring continuous crushing of medical waste.

[0139] In this design, the tilting assembly includes a convex disk 131, a gear 132, and an adjusting disk 137;

[0140] The convex disk 131 is capable of reciprocating in a fan-shaped trajectory in the vertical direction and stopping at the end of its swing.

[0141] The convex disk 131 is rotatably connected to the partition seat 120 on a fixed axis, and is coaxially fixed with the L-shaped side plate;

[0142] Gear 132 is located below convex disk 131 and is rotatably connected to partition seat 120 on a fixed axis;

[0143] Gear 132 is capable of reciprocating in the vertical direction;

[0144] An incompletely limiting round seat 133 is coaxially fixed on gear 132;

[0145] The convex disk 131 is provided with two sets of limiting arc grooves 134 and positioning grooves 135 that are slidably connected to the incomplete limiting round seat 133;

[0146] Gear 132 is provided with a locating pin 136;

[0147] The locating pin 136 is slidably connected to the locating groove 135;

[0148] The adjusting plate 137 is rotatably connected to the partition seat 120 on a fixed axis, and is also connected to the spline shaft 420 for transmission.

[0149] The adjustment plate 137 is provided with a rack 138 that meshes with the gear 132;

[0150] The separator 120 is provided with a slot that is slidably connected to the rack 138 in the horizontal direction;

[0151] The adjusting plate 137 has a fixed axis rotating rocker arm 139;

[0152] The end of the rocker arm 139 away from the adjustment plate 137 is rotatably connected to the rack 138 on a fixed axis.

[0153] like Figure 1 , 2 As shown in Figures 5, 6, and 7, the adjusting disk 137, which rotates on the fixed axis on the partition seat 120, is connected to the spline shaft 420 for transmission. When the spline shaft 420 rotates, it can drive the adjusting disk 137 to rotate synchronously. A freely deflecting rocker arm 139 is provided between the adjusting disk 137 and the rack 138. The rack 138 is slidably mounted on the partition seat 120 through a slot. Therefore, when the adjusting disk 137 rotates continuously, the rocker arm 139 can drive the rack 138 to reciprocate in the horizontal direction.

[0154] Meanwhile, the rack 138 meshes with the gear 132, and when the rack 138 reciprocates horizontally, it drives the gear 132 to reciprocate vertically. When the gear 132 rotates, it drives the positioning pin 136 and the incomplete limiting round seat 133 fixed on it to abut against a set of limiting arc grooves 134. As the gear 132 rotates, the positioning pin 136 slides on the positioning groove 135. At this time, the incomplete limiting round seat 133 moves away from the limiting arc groove 134. As the positioning pin 136 rotates, it can drive the convex disk 131 and the L-shaped side plate 113 to rotate a certain angle through the positioning groove 135, thereby changing the horizontal inclination angle of the central crushing roller 200, so that the medical waste sliding on it falls onto the side crushing roller 310 under the action of gravity.

[0155] Meanwhile, after the positioning pin 136 disengages from the positioning groove 135, the incomplete limiting round seat 133 abuts against another set of limiting arc grooves 134. Thus, through the limiting arc grooves 134 and the incomplete limiting round seat 133, the phenomenon of arbitrary rotation of the convex disk 131 under inertia and external force can be limited. Furthermore, as the gear 132 continues to rotate, the incomplete limiting round seat 133 slides and contacts the limiting arc groove 134 at the corresponding position, without causing the convex disk 131 to rotate. Therefore, after the convex disk 131 causes the L-shaped side plate and the central crushing roller 200 to deflect at a certain angle, it can stop for a period of time to allow the medical waste sliding on it to slide onto the side crushing roller 310.

[0156] Subsequently, as the gear 132 rotates in the opposite direction, it can drive the convex disk 131, the L-shaped side plate 113, and the central crushing roller 200 to return to their initial state. The incompletely limiting round seat 133 slides in contact with a set of limiting arc grooves 134, thereby ensuring the stability of the central crushing roller 200. Through the cooperation of the tilting component and the linkage component, and by being able to stop for a period of time at the end of the swing stroke, the difficult-to-crush parts are driven to slide onto the side crushing roller 310 while continuously crushing medical waste.

[0157] Furthermore, a second axial ball 210 is coaxially fixed at the end of the central crushing roller 200 away from the separator seat 120;

[0158] The housing 100 is provided with an arc-shaped ball cavity 140 that is slidably connected to the second axial ball 210;

[0159] The partition seat 120 is provided with an integrally formed guide bevel 121.

[0160] like Figure 1 , 5As shown in Figure 9, when the central crushing roller 200 swings, the second axial ball at its end slides on the arc-shaped ball cavity 140. The opening direction of the arc-shaped ball cavity 140 is consistent with the swing amplitude of the central crushing roller 200, and the arc-shaped ball cavity 140 can meet the rotation requirements of the second axial ball, thereby ensuring the stability of the second axial ball during rotation through the arc-shaped ball cavity 140.

[0161] At the same time, when the horizontal inclination angle of the central crushing roller 200 changes, medical waste that slips on the central crushing roller 200 can slide to one side of the separator seat 120 and slide through the guide inclined side 121 between the two sets of side crushing rollers 310, so that the bottle can be crushed by the inter-crushing component in the future.

[0162] This solution also includes a resistive material assembly;

[0163] The material blocking assembly includes a transverse shaft 510 and a comb plate 520;

[0164] The material blocking assembly is located at the lower part of the central crushing roller 200 and the side crushing roller 310;

[0165] Multiple sets of transverse shafts 510 are rotatably connected to the inner wall of the housing 100 on a fixed axis.

[0166] The transverse shaft 510 is connected to the gear 132 via a transmission connection.

[0167] The comb plate 520 is fixedly connected to the outer circumferential surface of the transverse shaft 510.

[0168] like Figure 1 As shown, when gear 132 reciprocates in the vertical direction, it can drive multiple sets of transverse shafts 510 connected to it to rotate synchronously. In actual use, gear 132 and transverse shafts 510 can be driven to rotate synchronously through pulleys. In the initial state, comb plate 520 is tilted downwards. As gear 132 reciprocates, comb plate 520 can swing back and forth in the vertical direction.

[0169] It should be noted that when the central crushing roller 200 and the side crushing roller 310 crush medical waste, the rotation of the central crushing roller 200 and the side crushing roller 310 will apply a downward thrust to the medical waste. The crushed waste will move downward under the action of gravity and this thrust. When the crushed medical waste falls at a high speed, the sprayed disinfectant may not be able to evenly cover the surface of the waste in a short time, resulting in the waste surface not being completely disinfected.

[0170] Therefore, by using the vertically oscillating comb plate 520, resistance can be provided to larger medical waste, thereby slowing down the falling speed of the medical waste, or an upward force can be applied to the medical waste, so that when the medical waste comes into contact with the comb plate 520, it can move upward to a certain height under this force before continuing to move downward, thereby increasing the residence time of the medical waste in the spray area, reducing the disinfection dead corners of the medical waste, and ensuring that the medical waste is disinfected more thoroughly.

[0171] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
