Description

Technical Field

[0001] This utility model relates to the field of pathogenic microorganism medical waste technology, and in particular to a microwave crushing and sterilization device for pathogenic microorganism medical waste. Background Technology

[0002] With the continuous advancement and widespread adoption of modern medical technology, the amount of pathogenic microbial medical waste generated is increasing year by year. This type of medical waste carries a large number of bacteria, viruses, and other pathogenic microorganisms. Improper disposal can not only cause serious pollution to the ecological environment but also pose a risk of triggering public health emergencies. Therefore, seeking safe and efficient treatment technologies has become a key issue in the field of medical waste management, and microwave crushing and sterilization technology has emerged as a leader due to its unique advantages.

[0003] Existing microwave crushing and sterilization equipment does not crush waste thoroughly enough, affecting subsequent processing.

[0004] To address this, a microwave crushing and sterilization device for pathogenic microorganism medical waste is proposed. Utility Model Content

[0005] In view of this, the present invention aims to provide a microwave crushing and sterilization device for pathogenic microorganism medical waste, so as to solve or alleviate the technical problems existing in the prior art, and at least provide a beneficial option.

[0006] The technical solution of this utility model embodiment is implemented as follows: A microwave crushing and sterilization device for pathogenic microorganism medical waste includes a main body and a discharge mechanism disposed on one side of the bottom of the main body. The main body includes: a working box, a first motor disposed at the bottom of the working box, a rotating rod disposed at the output end of the first motor, a forward crushing plate disposed at the bottom of the outer wall of the rotating rod, a reverse crushing plate disposed at the top of the outer wall of the rotating rod, a discharge door disposed at the top of the rotating rod, and a microwave generating body disposed on one side of the working box. The discharge mechanism includes a chassis disposed on one side of the working box, a limiting plate disposed inside the chassis, a feeding box disposed at the bottom of the limiting plate, a second motor disposed on one side of the feeding box, and a crushing rod disposed at the output end of the second motor.

[0007] In some embodiments, a collection box is provided at the bottom of the feeding box, and a collection trough is provided inside the collection box.

[0008] In some embodiments, the top of the work box is provided with a top plate, and the bottom of the top plate is provided with a sealing ring.

[0009] In some embodiments, a snap-fit ​​ring is provided at the bottom of the sealing ring, and a handle is provided at the top of the top plate.

[0010] The present invention has the following advantages due to the adoption of the above technical solution:

[0011] A microwave crushing and sterilization device for pathogenic microorganism medical waste, during operation, involves a first motor at the bottom of the working chamber driving a rotating rod to rotate. A forward crushing plate located at the bottom of the outer wall of the rotating rod and a reverse crushing plate at the top are staggered vertically. During operation, the forward and reverse crushing plates rotate synchronously, forming a bidirectional shearing and crushing space, capable of multi-dimensional tearing and cutting of medical waste in various forms, such as cotton-like, lumpy, or fibrous materials. The forward crushing plate, close to the inner wall of the working chamber, effectively crushes stubborn materials near the bottom of the container; the reverse crushing plate creates a reverse impact crushing effect on the rising waste. Combined with the through-type design of the rotating rod, this achieves three-dimensional crushing across the entire height range of the working chamber. After crushing, a limiting plate inside the chamber guides the material, and a second motor on one side of the discharge box drives the crushing rod to rotate, further refining the initially crushed material discharged from the main mechanism through the discharge door. This design further disperses any clumps of material that may have adhered after microwave sterilization.

[0022] Example 1:

[0023] like Figure 1-3As shown, a microwave crushing and sterilization device for pathogenic microorganism medical waste includes a main body 100 and a discharge mechanism 200 installed on one side of the bottom of the main body 100. The main body 100 includes: a working box 101, a first motor 102 installed at the bottom of the working box 101, a rotating rod 103 installed at the output end of the first motor 102, a forward crushing plate 104 integrally formed on the bottom of the outer wall of the rotating rod 103, a reverse crushing plate 105 integrally formed on the top of the outer wall of the rotating rod 103, a discharge gate 112 integrally formed on the top of the rotating rod 103, and a microwave generating body 113 installed on one side of the working box 101. The discharge mechanism 200 includes a chassis 202 installed on one side of the working box 101, a limiting plate 201 installed inside the chassis 202, a feeding box 203 installed at the bottom of the limiting plate 201, a second motor 204 installed on one side of the feeding box 203, and a crushing rod 205 installed at the output end of the second motor 204.

[0024] In this embodiment, a collection box 206 is installed at the bottom of the feeding box 203. A collection trough 207 is provided inside the collection box 206. After the fertilizer is crushed, it enters the collection trough 207 inside the collection box 206 for centralized collection.

[0025] In this embodiment, a top plate 108 is snapped onto the top of the working box 101, a sealing ring 109 is bonded to the bottom of the top plate 108, a snap ring 110 is bonded to the bottom of the sealing ring 109, and a handle 111 is installed on the top of the top plate 108. The top plate 108 is opened from the top of the working plate 101 by means of the handle 111 for feeding.

[0026] In this embodiment: During use, the first motor 102 at the bottom of the working box 101 drives the rotating rod 103 to rotate. The forward crushing plate 104 located at the bottom of the outer wall of the rotating rod 103 and the reverse crushing plate 105 located at the top are staggered vertically. During operation, the forward crushing plate 104 and the reverse crushing plate 105 rotate synchronously, forming a bidirectional shearing and crushing space, which can tear and cut medical waste of different forms such as cotton-like, blocky, or fibrous materials in multiple dimensions. The forward crushing plate 104, close to the inner wall of the working chamber 101, effectively crushes stubborn materials near the bottom of the container. The reverse crushing plate 105 creates a reverse impact crushing effect on the waste during the upward process. Combined with the through-type design of the rotating rod 103, it achieves three-dimensional crushing across the entire height range of the working chamber 101. After crushing, the limiting plate 201 inside the casing 202 guides the material, and the second motor 204 on one side of the discharge box 203 drives the crushing rod 205 to rotate, further refining the initially crushed material discharged from the main mechanism 100 through the discharge gate 112. This design can further disperse clumps of material that may adhere after microwave sterilization.
