[0002] Unified collection, transportation and treatment of medical waste can reduce pollution sources, save energy, avoid medical waste from mixing with domestic waste, and reduce harm to the human body. General medical waste disposal methods include disinfection and destruction and reduction, on-site incinerators, and centralized sanitary landfills.

[0003] Whether it is disinfection and destruction and reduction treatment, on-site incinerator, or centralized landfill, it needs to be crushed first and then proceed to the next process. The existing medical waste crusher is driven by a motor to rotate the knife roller. The rotating knife roller engages with the blade, which can directly crush the medical waste to the smallest size, making it convenient for subsequent processing equipment to dispose of the medical waste. However, in actual operation, the garbage is usually directly thrown onto the knife roller from the top opening of the crushing device. Part of the garbage accumulates on the side wall of the cavity and cannot be crushed well, which greatly reduces the crushing effect and affects the crushing efficiency.

[0004] Therefore, a medical waste crushing and processing device is proposed to solve the above problems. Utility Model Content

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] See also Figure 1-5 A medical waste crushing and processing device in this embodiment includes a crushing bin 1 with an opening at the top, and a crushing mechanism 2 is provided on the crushing bin 1. Medical waste is thrown into the crushing bin 1 from the top opening of the crushing bin 1, and the medical waste in the crushing bin 1 is crushed by the crushing mechanism 2. An opening is formed in the crushing bin 1, and the crushed materials can fall out through the bottom opening.

[0027] The crushing mechanism 2 includes a crushing roller 201 which is rotatably arranged in the crushing bin 1 through a rotating shaft, and fixed blades 202 which are spaced apart from the knife rings on the crushing roller 201 are arranged at the bottom of the crushing bin 1 and on both sides of the crushing roller 201, and a motor mounting seat 203 is placed beside the crushing bin 1, and a driving motor 204 is mounted on the motor mounting seat 203, and a reducer 205 is fixed on the side of the crushing bin 1, and the output shaft of the driving motor 204 is connected to the input end of the reducer 205 through a belt transmission member 206, and the output end of the reducer 205 is connected to the crushing roller 201. Guide plates 207 located above the fixed blades 202 are also fixed on both sides of the bottom opening of the crushing bin 1, and the garbage is guided to the crushing roller 201 through the guide plates 207 on both sides, and is crushed by the engagement of the rotating crushing roller 201 and the fixed blades 202.

[0028] The output shaft of the driving motor 204 rotates, and under the transmission of the belt transmission member 206 and the reducer 205, the crushing roller 201 can be driven to rotate, and the medical waste can be crushed through the engagement of the fixed blade 202.

[0029] The installation distance between the fixed blade 202 and the crushing roller 201 can be fine-tuned according to actual usage requirements. Two sets of blade mounting seats 208 are provided on the inner wall plane of the crushing bin 1. The two sets of fixed blades 202 are fastened to the two sets of blade mounting seats 208 by bolts respectively. Strip holes are provided on the blade mounting seats 208, and a plane is formed in the strip holes. The corresponding positions of the crushing bin 1 are provided with mounting holes threadedly connected to the bolts. The bolts are screwed into the crushing bin 1 through the strip holes, and the heads of the bolts are pressed against the plane inside the strip holes, so that the blade mounting seats 208 can be fastened to the inner wall of the crushing bin 1. By adjusting the distance between the blade mounting seats 208 and the crushing roller 201 and then locking them with bolts, the adjustment of the gap between the fixed blade 202 and the crushing roller 201 can be completed.

[0030] Since the inner side of the crushing bin 1 is arc-shaped, in order to prevent the garbage from accumulating on the arc-shaped side and not being completely crushed, a pushing mechanism 3 is also provided on one side of the crushing bin 1, which can push the garbage on the arc-shaped side to the crushing roller 201, so that the garbage can be completely crushed. Specifically, Figure 4 As shown, the pushing mechanism 3 includes an arc-shaped push plate 301 that rotates and slides in the crushing bin 1, a U-shaped rotating plate 302 is fixed to the top of the arc-shaped push plate 301, and the end of the U-shaped rotating plate 302 is rotatably arranged on the crushing bin 1 through a rotating shaft. A pair of driving cylinders 303 are hinged on the crushing bin 1, and the output shaft of the driving cylinder 303 is hinged on the U-shaped rotating plate 302.

[0031] The driving cylinder 303 is extended and retracted, and driven by the U-shaped rotating plate 302, the arc-shaped push plate 301 can rotate and realize the pushing effect of garbage, which can prevent the garbage from piling up on the arc-shaped side and being inconvenient to be completely crushed.

[0032] An arc-shaped gap is formed between the two arc-shaped side plates of the crushing bin 1 for the arc-shaped push plate 301 to rotate and slide, and a pair of limit bars 304 are fixed to the inner wall of the crushing bin 1 to limit the inner side surface of the arc-shaped push plate 301 so that the arc-shaped push plate 301 can slide smoothly in the crushing bin 1.

[0033] There is a notch on the other side of the crushing bin 1, which is convenient for inspecting the crushing roller 201 in the crushing bin 1. A blocking mechanism 4 is provided at the corresponding notch on the crushing bin 1. The blocking mechanism 4 blocks the notch on the side of the crushing bin 1 to prevent the crushed materials from falling from the notch when the crushing roller 201 is working. Specifically, Figure 5As shown, the blocking mechanism 4 includes a blocking frame 401 which is rotatably arranged on the side of the crushing bin 1 through a rotating shaft, and an arc-shaped protective sleeve 402 is also fixed to the inner side of the blocking frame 401. The arc-shaped protective sleeve 402 is provided with a material dropping notch 403. A pair of maintenance cylinders 404 are also hinged on the side of the crushing bin 1, and the output end of the maintenance cylinder 404 is hinged on the blocking frame 401.

[0034] like Figure 2 In the state shown, the arc-shaped protective sleeve 402 wraps the crushing roller 201, and the crushed debris leaks out through the material dropout gap 403 for collection. If the crushing roller 201 needs to be inspected, the inspection cylinder 404 is pushed out to push the blocking frame 401 and the arc-shaped protective sleeve 402 to rotate outward and expose the crushing roller 201.

[0035] By adopting the above-mentioned medical waste crushing and processing device, the medical waste can be completely crushed, and the crushing efficiency is improved. The specific crushing method is as follows:

[0036] Medical waste is thrown into the shredding bin 1 from the top opening of the shredding bin 1. The waste is guided to the shredding roller 201 through the guide plates 207 on both sides and rotated by the output shaft of the driving motor 204. The shredding roller 201 is driven to rotate by the belt transmission part 206 and the reducer 205, and the medical waste can be shredded by engaging with the fixed blade 202. The driving cylinder 303 is extended and retracted. Driven by the U-shaped rotating plate 302, the arc-shaped push plate 301 can rotate, and the waste on the arc-shaped side of the shredding bin 1 can be pushed to the shredding roller 201, so that the waste is completely shredded.

[0037] The control method of the present invention is controlled by a controller. The control circuit of the controller can be realized by simple programming by technicians in this field. The provision of power is also common knowledge in this field. The present invention is mainly used to protect mechanical devices, so the present invention will no longer explain the control method and circuit connection in detail.
