[0043] Exemplary embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.
[0044] like Figures 1-5 As shown, this utility model provides a medical waste screw conveyor, comprising:
[0045] Conveyor cylinder 1;
[0046] Feed pipe 5 is connected to the upper surface of conveyor cylinder 1;
[0047] The discharge pipe 6 is connected to the bottom surface of the conveying cylinder 1, and the discharge pipe 6 and the feed pipe 5 are respectively close to the two ends of the conveying cylinder 1 along its length.
[0048] Rotate the conveyor shaft 2, which is located inside the conveyor cylinder 1;
[0049] A drive assembly is provided at the end of the conveyor cylinder 1, and the drive assembly is connected to the conveyor shaft 2;
[0050] Spiral blades 3 are connected to the outside of the conveyor shaft 2;
[0051] Multiple wedge-shaped blocks 4 are connected to the conveying surface of the spiral blade 3;
[0052] Multiple filter holes 101 are provided through the inner wall of the lower half of the conveying cylinder 1.
[0053] In this embodiment, the crushed and disinfected fibers and heavy particles enter the conveying cylinder 1 through the feed pipe 5. The drive assembly drives the conveying shaft 2 to rotate, and the spiral blades 3, along with the rotating conveying shaft 2, convey the fibers to the discharge pipe 6. During the conveying process, multiple wedges 4 on the conveying surface of the spiral blades 3 come into contact with the fibers and heavy particles. The multiple wedges 4 break up the fibers and heavy particles, causing the heavy particles to fall to the lower inner wall of the conveying cylinder 1 under the action of gravity and be discharged through the filter holes 101. The separation and filtration of fibers and heavy particles are achieved during the conveying process, which helps to improve the efficiency of medical waste treatment and reduce equipment costs.
[0054] In this embodiment, when the spiral blade 3 pushes the fiber material to move towards the discharge pipe 6, the surface of the spiral blade 3 that is in contact with the fiber material is the conveying surface of the spiral blade 3.
[0055] In this embodiment, the gap between the spiral blade 3 and the inner wall of the conveying cylinder 1 is smaller than the particle size of the heavy particles. With this arrangement, the spiral blade 3 can push the heavy particles and discharge them from the filter hole 101, which helps to ensure that the heavy particles are discharged completely and improves the discharge effect and efficiency of the heavy particles.
[0056] In this embodiment, the wedge block 4 can be a block structure or a hemispherical structure. In specific applications, the structure and size of the wedge block 4 can be adjusted according to the characteristics of the fibrous material and heavy particles. No specific limitation is made here.

[0059] In this embodiment, the support frame 13 enables the conveying cylinder 1 to be distributed in an inclined structure, and the position of the discharge pipe 6 is higher than that of the feed pipe 5. This allows the dispersed heavy particles to be separated from the fibrous material smoothly, and facilitates the heavy particles to fall to the lower half of the conveying cylinder 1 under the action of gravity and be discharged through the filter hole 101.
[0060] The drive assembly is located near the discharge pipe 6. The support frame 13 ensures that the drive assembly and the conveying cylinder 1 are in a stable state, thus guaranteeing the overall stability.

[0065] In this embodiment, a stable triangular structure is formed by the supporting base column 1302 and two supporting inclined columns 1301, ensuring the overall stability of the support frame 13; the arc-shaped support plate 1303 is fixedly connected to the bottom surface of the conveying cylinder 1, ensuring the connection stability between the support frame 13 and the conveying cylinder 1, thereby helping to improve the support stability of the support frame 13 on the conveying cylinder 1.

[0069] Driven pulley 11 is connected to the end of conveyor shaft 2. Driven pulley 11 corresponds to drive pulley 9, and a drive belt 10 is meshed between driven pulley 11 and drive pulley 9.
[0070] In this embodiment, the drive motor 7 operates and drives the conveyor shaft 2 to rotate through the active pulley 9, the transmission belt 10 and the driven pulley 11, thereby ensuring that the conveyor shaft 2 drives the spiral blade 3 to rotate stably and realize the stable conveying of the fibrous material.
[0071] like Figure 4 As shown, in an optional embodiment of the present invention, the motor mount 8 includes:
[0072] Arc-shaped connecting plate 803 is adapted to the upper surface of conveying cylinder 1 and is connected to the upper surface of conveying cylinder 1.
[0073] Mounting plate 811, which is connected to drive motor 7;
[0074] Support plate 802 is connected between arc-shaped connecting plate 803 and mounting plate 811. Two support plates 802 are provided, and the two support plates 802 are symmetrically distributed on both sides of arc-shaped connecting plate 803.
[0075] In this embodiment, the arc-shaped connecting plate 803 achieves a stable connection between the motor base 8 and the upper surface of the conveying cylinder 1, which helps to ensure the stability of the motor base 8.
[0076] The mounting plate 811 is supported by two support plates 802, which ensures the stability of the mounting plate 811. The drive motor 7 is mounted on the mounting plate 811, which ensures the stability of the drive motor 7 and can stably drive the conveyor shaft 2 to rotate, thus ensuring the stable conveying of the fibrous material.

[0078] The protective cover 12 has two sides connected to two support plates 802 respectively. The driving pulley 9, the transmission belt 10 and the driven pulley 11 are all located in the inner cavity of the protective cover 12.
[0079] In this embodiment, the driving pulley 9, the transmission belt 10, and the driven pulley 11 are protected by the protective cover 12 to prevent other debris from affecting the normal transmission of the driving pulley 9, the transmission belt 10, and the driven pulley 11.
[0080] like Figure 3 As shown, in an optional embodiment of the present invention, a plurality of wedge blocks 4 are evenly distributed on the conveying surface of the spiral blade 3 along the spiral direction of the spiral blade 3.
[0081] In this embodiment, by uniformly distributing multiple wedge blocks 4 on the conveying surface of the spiral blade 3 along the spiral direction of the spiral blade 3, it helps to improve the dispersing effect of the wedge blocks 4 on the fibrous material and heavy particles, ensuring that the heavy particles can be fully separated from the fibrous material, thereby helping the heavy particles fall into the lower half of the conveying cylinder 1 and be discharged through the filter hole 101, which helps to improve the discharge effect and efficiency of the heavy particles.

[0087] In this embodiment, by using a filter hole 101 with a conical hole structure, heavy particles entering the filter hole 101 can be quickly discharged, which helps to improve the filtration efficiency of heavy particles.
[0088] The medical waste screw conveyor provided in the above embodiments of this utility model, by uniformly arranging multiple wedge blocks 4 on the conveying surface of the screw blade 3, enables the wedge blocks 4 to rotate with the screw blade 3, and the wedge blocks 4 to fully contact the fibrous material, thereby fully dispersing the fibrous material and heavy particles, which helps to improve the dispersion and separation effect of fibrous material and heavy particles; the heavy particles fall to the lower half of the conveying cylinder 1 under the action of gravity and are discharged through the filter hole 101, which can realize the separation of heavy particles and fibrous material. The separation and filtration of fibrous material and heavy particles during the conveying process helps to improve the efficiency of medical waste treatment and reduce equipment costs.
