Therefore, a new medical waste collection device is proposed. Utility Model Content

[0005] To address the aforementioned problems, a medical waste collection device is provided. This device utilizes a crushing mechanism to crush the waste, which then falls onto a mesh conveyor belt. Simultaneously, a third servo motor drives a second driven gear and a third driven gear to rotate via a second driving gear. As the second driven gear rotates, the mesh conveyor belt pulls the waste closer to the pressure roller. When the third driven gear rotates, it drives the pressure roller to rotate synchronously, causing the pressure roller and the mesh conveyor belt to work together to compress the waste, thus separating residual medication from the waste. This solves the problem of incomplete removal of residual medication from waste.

[0006] To address the problems of existing technologies, this application provides a medical waste collection device, including a collection device body, a mounting frame disposed on the top of the collection device body, a crushing mechanism disposed on the top of the mounting frame for crushing waste, and a conveying mechanism disposed inside the collection device body for separating waste. The conveying mechanism includes two sets of horizontally arranged second rotating shafts, with both ends of the second rotating shafts rotatably mounted on the inner wall of the collection device body. A second driven gear is fixedly mounted at the extension end of one set of second rotating shafts. Several pulleys are equidistantly mounted on the outside of the two sets of second rotating shafts. A mesh conveyor belt is sleeved on the outside of the pulleys, and the inner surface of the mesh conveyor belt can mesh with the outside of the pulleys. A pressing roller for squeezing waste is also horizontally arranged inside the collection device body. The bottom of the pressing roller can contact the upper end surface of the mesh conveyor belt, and a third driven gear is disposed at the extension end of the pressing roller. A third servo motor is disposed on the side of the collection device body near the top, and a second driving gear that can mesh with the third driven gear and the second driven gear is fixedly mounted at the output end of the third servo motor.

[0007] As one technical solution of this application, the crushing mechanism includes a feeding port fixed to the top of the mounting frame for discharging waste. A main crushing roller is horizontally arranged at the center of the feeding port. A first servo motor for driving the main crushing roller to rotate is fixed on the outside of the feeding port. The output end of the first servo motor is fixedly connected to one end of the main crushing roller. A first drive gear that can rotate is arranged on the side of the feeding port away from the first servo motor. The first drive gear is fixed to the extension end of the main crushing roller. A secondary crushing roller is arranged on one side of the main crushing roller. The two ends of the secondary crushing roller are rotatably installed on the inner wall of the feeding port. A first driven gear that can mesh with the first drive gear is arranged at the extension end of the secondary crushing roller.

[0008] As one technical solution of this application, the inside of the feeding port is provided with a cleaning mechanism on both sides for cleaning the main crushing roller and the auxiliary crushing roller, and the cleaning mechanism is provided with a cleaning groove that can be adapted to the main crushing roller and the auxiliary crushing roller.

[0009] As one technical solution of this application, the top of the mounting bracket is provided with an air purification device for purification. The air purification device includes a shroud that can communicate with the interior of the main body of the collection device.

[0014] The advantages of this utility model compared to the prior art are:

[0015] This application utilizes a crushing mechanism to crush waste materials. The crushed waste falls onto a mesh conveyor belt. Simultaneously, a third servo motor drives a second driven gear and a third driven gear to rotate via a second driving gear. As the second driven gear rotates, the mesh conveyor belt pulls the waste material closer to the pressure roller. When the third driven gear rotates, it drives the pressure roller to rotate synchronously, causing the pressure roller and the mesh conveyor belt to work together to compress the waste, thus separating the residual chemicals carried within the waste. This solves the problem of incomplete removal of residual chemicals from waste. Attached Figure Description

[0023] To further understand the features, technical means, and specific objectives and functions achieved by this utility model, the following detailed description is provided in conjunction with the accompanying drawings and specific embodiments.

[0024] See Figures 1-6 As shown, a medical waste collection device includes a collection device body 1, a mounting frame 2 disposed on the top of the collection device body 1, a crushing mechanism 3 disposed on the top of the mounting frame 2 for crushing waste, and a conveying mechanism 6 disposed inside the collection device body 1 for separating waste. The conveying mechanism 6 includes two sets of horizontally arranged second rotating shafts 61, the two ends of which are rotatably mounted on the inner wall of the collection device body 1. A second driven gear 64 is fixedly mounted on the extended end of one set of second rotating shafts 61, and a plurality of leather straps are equidistantly mounted on the outside of the two sets of second rotating shafts 61. The pulley 62 is fitted with a mesh conveyor belt 63. The inner surface of the mesh conveyor belt 63 can mesh with the outer surface of the pulley 62. Inside the main body 1 of the collection device, a pressing roller 65 for squeezing waste is also horizontally arranged. The bottom of the pressing roller 65 can contact the upper end surface of the mesh conveyor belt 63. The extended end of the pressing roller 65 is provided with a third driven gear 66. A third servo motor 7 is arranged on the side of the main body 1 near the top. The output end of the third servo motor 7 is fixed with a second driving gear 71 that can mesh with the third driven gear 66 and the second driven gear 64.

[0025] During the process of removing residual medicine from the waste, the third servo motor 7 drives the second drive gear 71 to rotate. The rotation of the second drive gear 71 synchronously drives the second driven gear 64 and the third driven gear 66 to rotate. When the waste falls onto the mesh conveyor belt 63, the mesh conveyor belt 63 gradually moves the waste closer to the pressure roller 65. As the waste approaches the pressure roller 65, it can pass through the gap between the pressure roller 65 and the mesh conveyor belt 63. When the waste is located between the mesh conveyor belt 63 and the pressure roller 65, the mesh conveyor belt 63 and the pressure roller 65 work together to squeeze out the residual medicine inside the waste, causing the residual medicine in the waste to separate from it. The separated medicine then falls through the holes on the mesh conveyor belt 63.

[0026] See Figure 3 and Figure 6 As shown, the crushing mechanism 3 includes a feeding port 31 fixed to the top of the mounting frame 2 for discharging waste. A main crushing roller 33 is horizontally arranged at the center of the feeding port 31. A first servo motor 32 for driving the main crushing roller 33 to rotate is fixed on the outside of the feeding port 31. The output end of the first servo motor 32 is fixedly connected to one end of the main crushing roller 33. A first drive gear 34 that can rotate is arranged on the side of the feeding port 31 away from the first servo motor 32. The first drive gear 34 is fixed to the extension end of the main crushing roller 33. A secondary crushing roller 35 is arranged on one side of the main crushing roller 33. The two ends of the secondary crushing roller 35 are rotatably installed on the inner wall of the feeding port 31. A first driven gear 36 that can mesh with the first drive gear 34 is arranged on the extension end of the secondary crushing roller 35.

[0027] During the waste crushing process, the first servo motor 32 is activated, effectively driving the main crushing roller 33 to rotate. A first driving gear 34 is located at the end of the main crushing roller 33 furthest from the first servo motor 32. When rotating, the first driving gear 34 engages synchronously with the first driven gear 36. As the first driven gear 36 rotates, it synchronously drives the auxiliary crushing roller 35 to rotate. This allows the main crushing roller 33 and the auxiliary crushing roller 35 to cooperate effectively in crushing the waste.

[0028] See Figure 3 and Figure 6 As shown, cleaning mechanisms 37 for cleaning the main crushing roller 33 and the auxiliary crushing roller 35 are provided on both sides inside the inlet 31. The cleaning mechanism 37 is provided with cleaning grooves 371 that can be adapted to the main crushing roller 33 and the auxiliary crushing roller 35.

[0029] Cleaning mechanisms 37 are installed on both sides of the inlet 31. One side of each cleaning mechanism 37 has a cleaning groove 371, the size and shape of which are adapted to the main crushing roller 33 and the auxiliary crushing roller 35. This allows the cleaning groove 371 to clean the cutting edges of the main crushing roller 33 and the auxiliary crushing roller 35 in real time, effectively preventing waste from entangled on the crushing rollers and ensuring that the auxiliary crushing roller 35 and the main crushing roller 33 do not experience waste entanglement during the waste crushing process.

[0030] See Figure 1 and Figure 4 As shown, an air purification device 5 for purification is provided on the top of the mounting bracket 2. The air purification device 5 includes a shroud 51 that can communicate with the inside of the collection device body 1. A first rotating shaft 54 ​​that can rotate is arranged longitudinally inside the shroud 51. A fan blade 55 that can drive the exhaust gas inside the collection device body 1 is fixed to the outside of the first rotating shaft 54. A second servo motor 53 for driving the first rotating shaft 54 ​​to rotate is provided on the top of the shroud 51. The top end of the first rotating shaft 54 ​​is fixedly connected to the output end of the second servo motor 53.

[0031] When the second servo motor 53 starts, the first rotating shaft 54 ​​at the output end of the second servo motor 53 will rotate synchronously. The rotation of the first rotating shaft 54 ​​further drives the fan blades 55 to rotate. During the rotation of the fan blades 55, the fan blades 55 will cause the air inside the main body 1 of the collecting device to flow upward. This air is then smoothly discharged to the outside of the main body 1 of the collecting device through the pre-reserved slot at the top of the rectifier 51. This ensures that the air inside the main body 1 of the collecting device can be discharged smoothly, effectively preventing the accumulation of harmful gases inside the main body 1 of the collecting device, thereby maintaining the cleanliness and safety of the internal environment of the device.

[0032] See Figure 1 and Figure 4 As shown, the air purification device 5 also includes a filter element 56 fixed to the bottom of the rectifier 51 for filtering the exhaust gas inside the collection device body 1.

[0033] During the process of the fan blade 55 driving the gas inside the main body 1 of the collection device upward, the gas needs to be filtered through the filter element 56 so that the filter element 56 can filter the harmful substances in the gas inside the main body 1 of the collection device, and avoid the emission of harmful gases causing air pollution.

[0034] See Figure 1 and Figure 4 As shown, the mounting bracket 2 includes a maintenance plate 21 that can be used to mount the fairing 51.

[0035] The inspection plate 21 is fixedly installed on the top of the main body 1 of the collection device, and also serves to stabilize the fairing 51 on the top of the main body 1 of the collection device. This allows for easy maintenance of the waste collection device's interior by simply removing the inspection plate 21 when maintenance is needed. This not only improves the convenience of maintenance operations but also helps extend the overall service life of the waste collection device.

[0036] See Figure 2 As shown, a waste liquid collection tank 13 for collecting waste liquid is provided at the bottom of the main body 1 of the collection device; a waste collection tank 14 for storing waste is provided on the side of the main body 1 of the collection device near the waste liquid collection tank 13.

[0037] When the waste is squeezed by the mesh conveyor belt 63 and the pressure roller 65, the residual liquid inside the waste will fall through the drain on the mesh conveyor belt 63 into the waste liquid collection tank 13 for storage. At the same time, solid waste will fall into the waste collection tank 14 under the action of the mesh conveyor belt 63 for storage. This achieves solid-liquid separation and storage of waste in the waste collection device.

[0038] See Figure 2 As shown, a controller 12 for controlling the operation of the collection device is provided on one side of the main body 1 of the collection device.

[0039] By installing a controller 12 on one side of the main body 1 of the collection device, the user can control the operation of the waste collection device through the controller 12, making it more convenient to use.

[0040] The above embodiments only illustrate one or more implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
