[0093] The prior art realizes the pulverization process of medical waste through a crushing device, but the medical waste contains bottles such as medicine bottles and medical glassware, especially infusion glass bottles with larger diameters. When using crushing rollers for crushing, such bottles may slip on the crushing rollers, resulting in poor crushing effect.

[0094] In view of this, if Figures 1 to 9 As shown, the present solution provides a medical waste treatment device to alleviate the above-mentioned problems. The device comprises a housing 100 and a central crushing roller 200, including a damage assessment mechanism and an intermittent crushing assembly disposed in the housing 100;

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

[0096] The two sets of side crushing rollers 310 are respectively connected to a set of end seats 320 for fixed axis rotation;

[0097] The housing 100 is provided with a transverse slide 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 toward or away from each other in the horizontal direction and to rotate freely in the vertical direction synchronously;

[0099] The housing 100 is also provided with a linkage assembly for controlling the synchronous rotation of the central crushing roller 200 and the side crushing roller 310;

[0100] A separation seat 120 is provided between the central 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 partition seat 120 is provided with a tilting assembly;

[0103] The tilting assembly can control the glass bottles that slip on the central crushing roller 200 to move to the side crushing rollers 310 .

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

[0105] At the same time, when smooth cylindrical objects such as medicines or infusion glass bottles in medical waste slip between the two center crushing rollers 200, the tilting assembly will drive the two sets of center crushing rollers 200 to deflect a certain angle in the vertical direction. During the deflection, the center crushing roller 200 tilts toward the side close to the side crushing roller 310, so that the medical waste that slips slides to the side of the side crushing roller 310 under the action of gravity.

[0106] Furthermore, two groups of side crushing rollers 310 are respectively arranged on a group of end seats 320. Under the drive of the inter-crushing assembly, the two groups of end seats 320 and the side crushing rollers 310 arranged thereon can move synchronously toward or away from each other in the horizontal direction, and the side crushing rollers 310 are always in a rotating state during the horizontal movement, thereby crushing the medical waste thereon by the two groups of side crushing rollers 310 that are continuously rotating and have a constant spacing.

[0107] During the operation of the edge crushing rollers 310, the distance between the two groups of edge crushing rollers 310 changes dynamically, thereby changing the force position and state of the medical waste between the edge crushing rollers 310, increasing the possibility of it being caught, squeezed and crushed; when the distance shrinks, the clamping and crushing force on the medical waste is increased, and the difficult-to-crush medical waste is crushed; when the distance expands, the position and posture of the difficult-to-crush medical waste is changed to avoid its continuous slippage on the surface of the edge crushing rollers 310; at the same time, the change in the distance will cause the difficult-to-crush medical waste to be intermittently squeezed, breaking the balance between the medical waste and the edge crushing rollers 310 during the slip process, forcing the medical waste to shift and flip; the periodic change in the distance, combined with the rotation of the edge crushing rollers 310, can generate shear force with constantly changing force directions, exert destructive forces in different directions on the medical waste, further reduce the slippage phenomenon, and ensure that the bottle body can be broken to release the residual liquid waste therein.

[0108] In this solution, the intermittent component includes a support frame 410, a spline shaft 420 and a worm gear 322;

[0109] Both ends of the spline shaft 420 are respectively connected to a support frame 410 for fixed-axis rotation;

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

[0111] A worm 430 is sleeved on the spline shaft 420;

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

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

[0114] The worm gear 322 is disposed on the end seat 320 and is rotatably connected to the end seat 320;

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

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

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

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

[0119] The short connecting rod 323 is rotatably connected to the long connecting rod 324;

[0120] One 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, the spline shaft 420 between the two groups of support frames 410 is controlled to rotate continuously in the vertical direction by a motor fixed on the housing 100, wherein a worm 430 is sleeved on the housing 100, and then the worm 430 is driven to rotate synchronously when the spline shaft 420 rotates, the worm 430 is meshingly connected with a worm wheel 322, and the worm 430 is located between the accommodating grooves 321 opened on the worm wheel 322, and at the same time, the worm wheel 322 drives the coaxial short connecting rod 323 thereon to rotate when rotating, and a freely deflecting long connecting rod 324 is arranged between the short connecting rod 323 and the support frame 410, therefore, when the spline shaft 420 rotates, the end seat 320 can be driven to reciprocate in the horizontal direction through the worm 430 and the worm wheel 322, and the worm wheel 322 is coaxially fixed with the edge crushing roller 310, thereby driving the edge crushing roller 310 to continuously rotate in the vertical direction 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 respectively fixedly rotated on the short connecting rod 323 and the support frame 410, and the short connecting rod 323 rotates synchronously with the worm gear 322. Therefore, the long connecting rod 324 can be deflected synchronously when the worm gear 322 rotates, and under the restriction of the long connecting rod 324, when the worm gear 322 continues to rotate, its horizontal position changes back and forth in the horizontal direction, thereby driving the end seat 320 and the side crushing roller 310 to reciprocate in the horizontal direction, and then driving the distance between the two sets of side crushing rollers 310 to continuously change within a certain range, so as to avoid continuous slippage of the bottle body thereon, thereby ensuring that the bottle body can be broken and the liquid waste therein can be released.

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

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

[0125] Specifically, a partition seat 120 is arranged between the side crushing roller 310 and the center crushing roller 200. In order to ensure the stability of the side crushing roller 310 during rotation and horizontal movement, a transverse ball cavity 122 for sliding connection of the first axial ball 330 is arranged on the partition seat 120, and the first axial ball 330 and the side crushing roller 310 are coaxially fixed, so that the transverse ball cavity 122 can form the first axial ball 330 and the side crushing roller 310, and the transverse ball cavity 122 can meet the rotation movement of the first axial ball 330, thereby ensuring the stability of the two groups of side crushing rollers 310 during movement.

[0126] In this solution, the linkage assembly includes a directional isotropic disk 111, a positioning plate 112, an L-shaped side plate 113, and a swing isotropic disk 114;

[0127] The directional alignment disk 111 is disposed on the partition seat 120 and is rotatably connected to the partition seat 120;

[0128] The directional alignment disk 111 is drivingly connected to the spline shaft 420;

[0129] A plurality of active direction transmission columns 115 arranged in a circular array are provided on one side of the directional alignment disk 111 away from the partition seat 120;

[0130] The positioning plate 112 is fixedly connected to the partition seat 120;

[0131] The positioning plate 112 is connected to the L-shaped side plate 113 for fixed-axis rotation;

[0132] One 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 alignment disc 114 is coaxially fixed with the central crushing roller 200;

[0134] A plurality of groups of driven transmission posts 116 arranged in a circular array are provided on one side of the swing alignment disk 114 close to the directional alignment disk 111;

[0135] The multiple groups of active steering columns 115 and driven steering columns 116 are arranged in an interlaced manner, and the connected active steering columns 115 and driven steering columns 116 are slidably connected to each other.

[0136] like Figure 1 , 2 As shown in Figures 5 and 6, the directional isotropic disk 111 is connected with the spline shaft 420 by transmission. When the spline shaft 420 rotates, the directional isotropic disk 111 and the multiple groups of active steering columns 115 thereon can be driven to rotate synchronously. The multiple groups of active steering columns 115 and the driven steering columns 116 are staggered and in sliding contact with each other. Therefore, when the directional isotropic disk 111 rotates, the swing isotropic disk 114 can be driven to rotate synchronously in the vertical direction through the active steering columns 115 and the driven steering columns 116.

[0137] At the same time, the swing-to-isolating disk 114 and the center crushing roller 200 are coaxially arranged, so that when the spline shaft 420 drives the side crushing roller 310 to rotate through the inter-crushing assembly, the center crushing roller 200 can be driven to rotate synchronously. In addition, the swing-to-isolating disk 114 is arranged on the L-shaped side plate 113, and the L-shaped side plate 113 rotates around a fixed axis with the positioning plate 112 fixedly arranged on the partition seat 120. In actual use, the L-shaped side plate 113 is driven to deflect a certain angle in the vertical direction through the swing-tilting assembly, so that the inclination angle of the center crushing roller 200 in the horizontal direction can be changed.

[0138] Moreover, when the horizontal inclination angle of the L-shaped side plate 113 and the central crushing roller 200 changes, the swing-to-isolating disk 114 and the driven transmission column 116 thereon deflect synchronously, and the swing-to-isolating disk 114 can still rotate synchronously with the fixed isotropic disk through the driven transmission column 116 and the active transmission column 115, so that when the central crushing roller 200 deflects in the vertical direction, its slope foot can face one side of the side crushing roller 310, and under the trend of the linkage component, it can ensure that the central crushing roller 200 always keeps rotating, thereby ensuring the continuous crushing of medical waste.

[0139] In this solution, the tilting assembly includes a convex plate 131, a gear 132 and an adjustment plate 137;

[0140] The convex disk 131 can reciprocate in a vertical direction in a fan-shaped trajectory and stop at the end of the swing;

[0141] The convex plate 131 is rotatably connected to the partition seat 120 and is coaxially fixed to the L-shaped side plate;

[0142] The gear 132 is disposed below the convex plate 131 and is rotatably connected to the partition seat 120;

[0143] The gear 132 can reciprocate in the vertical direction;

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

[0145] The convex disc 131 is provided with two sets of limiting arc grooves 134 and positioning grooves 135 which are slidably connected with the incomplete limiting circular seat 133;

[0146] The gear 132 is provided with a positioning pin 136;

[0147] The positioning pin 136 is slidably connected to the positioning slot 135;

[0148] The adjustment plate 137 is connected to the partition seat 120 for fixed-axis rotation, and is also connected to the spline shaft 420 for transmission;

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

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

[0151] A swing rod 139 is provided on the adjustment plate 137 to rotate on a fixed axis;

[0152] One end of the swing rod 139 away from the adjustment plate 137 is connected to the rack 138 for fixed-axis rotation.

[0153] like Figure 1 , 2 As shown in Figures 5, 6 and 7, the fixed-axis rotating adjustment disk 137 on the partition seat 120 is transmission-connected with the spline shaft 420. When the spline shaft 420 rotates, the adjustment disk 137 can be driven to rotate synchronously, and a freely deflecting rocker bar 139 is arranged between the adjustment disk 137 and the rack 138, and the rack 138 is slidably arranged on the partition seat 120 through a slot. Therefore, when the adjustment disk 137 continues to rotate, the rack 138 can be driven to reciprocate in the horizontal direction through the rocker bar 139.

[0154] At the same time, the rack 138 is meshed with the gear 132, so that when the rack 138 reciprocates horizontally, the gear 132 is driven to reciprocate in the vertical direction, and when the gear 132 rotates, the positioning pin 136 fixed thereon and the incomplete limiting circular seat 133 are driven to contact and connect with a group 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 circular seat 133 is away from the limiting arc groove 134, and as the positioning pin 136 rotates, the convex disk 131 and the L-shaped side plate 113 can be driven to rotate a certain angle through the positioning groove 135, thereby changing the horizontal inclination angle of the central crushing roller 200, so as to drive the medical waste sliding on it to slide onto the side crushing roller 310 under the action of gravity.

[0155] At the same time, after the positioning pin 136 is disengaged from the positioning groove 135, the incomplete limiting circular seat 133 is in contact with another set of limiting arc grooves 134, and then through the limiting arc grooves 134 and the incomplete limiting circular seat 133, the convex disk 131 can be limited to rotate arbitrarily under the action of inertia and external force factors. In addition, as the gear 132 continues to rotate, the incomplete limiting circular seat 133 slides in contact with the limiting arc grooves 134 at the corresponding position and will not drive the convex disk 131 to rotate. Therefore, after the convex disk 131 drives the L-shaped side plate and the center crushing roller 200 to deflect a certain angle, it can stay for a period of time to give the medical waste sliding on it a certain time to slide onto the side crushing roller 310.

[0156] Subsequently, as the gear 132 rotates in the opposite direction, the convex disk 131, the L-shaped side plate 113 and the center crushing roller 200 can be driven to return to the initial state, and the incomplete limiting round seat 133 and a set of limiting arc grooves 134 are in sliding contact, thereby ensuring the stability of the center crushing roller 200. Through the mutual cooperation of the tilting assembly and the linkage assembly, it can stay at the end position of the swing for a period of time, and then while continuing to crush the medical waste, the difficult-to-crush part is driven to slide to the side crushing roller 310.

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

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

[0159] An integrally formed guiding bevel portion 121 is disposed in the partition seat 120 .

[0160] like Figure 1 , 5As shown in Figure 9, when the center crushing roller 200 swings, the second axial ball arranged 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 center 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, the medical waste that slips on the central crushing roller 200 can slide to one side of the partition seat 120, and can slide between the two groups of side crushing rollers 310 through the guiding bevel portion 121, so as to facilitate the subsequent crushing of the bottle body through the inter-crushing assembly.

[0162] In this solution, a material blocking component is also included;

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

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

[0165] A plurality of sets of transverse shafts 510 are rotatably connected to the inner wall of the housing 100;

[0166] The transverse shaft 510 is in transmission connection with the gear 132;

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

[0168] like Figure 1 As shown, when the gear 132 rotates back and forth in the vertical direction, it can drive the multiple groups of transverse shafts 510 connected thereto to rotate synchronously. In actual use, the gear 132 and the transverse shaft 510 can be driven to rotate synchronously by a pulley. In the initial state, the comb plate 520 is tilted downward, and as the gear 132 rotates back and forth, the 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 the 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, and the crushed waste will move downward under the action of gravity and the thrust. When the crushed medical waste falls at a higher 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 swinging the comb plate 520 back and forth in the vertical direction, resistance can be provided to medical waste of larger size, thereby slowing down the falling speed of the medical waste, or an upward force can be applied to the medical waste to drive the medical waste to move upward to a certain height under the force when it comes into contact with the comb plate 520 when falling, and then continue to move downward, thereby increasing the residence time of the medical waste in the spraying area, reducing the blind spots of disinfection 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, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements 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.
