Detailed Implementation

[0041] Exemplary embodiments of the present invention will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention 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 invention will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

[0042] like Figures 1 to 6 As shown, an embodiment of this utility model proposes a shaftless stirring and discharging device, comprising:

[0043] The sterilization tank 1 has a cavity inside, and one end of the sterilization tank 1 has a discharge port 5 communicating with the cavity, and the other end has a connection hole communicating with the cavity.

[0044] A drive device is provided at the other end of the sterilization tank 1, and the output end of the drive device passes through the connection hole and is located in the accommodating cavity of the sterilization tank 1.

[0045] The spiral shaftless blade 2 is disposed in the cavity of the sterilization tank 1. One end of the spiral shaftless blade 2 is connected to the output end of the drive device, and the other end is disposed at the end of the cavity.

[0046] A discharge gate 51 is installed on the sterilization tank 1 and located at the discharge port 5.

[0047] The feed inlet 6 is located at the top of the sterilization tank 1.

[0048] In this embodiment, the discharge gate 51 is used to control the opening and closing of the discharge port 5 of the sterilization tank 1. The design of the discharge gate 51 is not unique, as long as it can satisfy the function of closing and opening the discharge port 5 of the sterilization tank 1. In a preferred embodiment, two slide rails are arranged opposite to each other on both sides of the discharge port 5 of the sterilization tank 1. The two sides of the discharge gate 51 are engaged with the two slide rails and are slidably connected to the slide rails. The spiral shaftless blade 2 is made of high-strength and corrosion-resistant material, has good wear resistance and service life, and can withstand the wear and corrosion of medical waste.

[0049] In this embodiment, the shaftless stirring and discharging device can be used in a medical waste sterilization system for stirring during the sterilization process. In use, the discharge gate 51 is closed, and the material enters the cavity of the sterilization tank 1 through the inlet 6. Then, the drive device is activated, driving the spiral shaftless impeller 2 to rotate, thereby stirring the material in the cavity. After stirring, the discharge gate 51 is opened, and the drive device drives the spiral shaftless impeller 2 to rotate towards the discharge port 5, thus discharging the material. In this embodiment, the spiral shaftless impeller 2 serves both a stirring and discharging function during operation, enabling the medical waste to be properly stirred and discharged. The materials are thoroughly mixed during the processing, improving the sterilization effect. Simultaneously, continuous stirring prevents material accumulation and clumping, ensuring smooth processing. The discharge function utilizes the rotational motion of the shaftless mixing discharge device to expel the processed medical waste from the discharge port 5. The design of the spiral shaftless paddle 2 makes discharge smoother and less prone to clogging, improving discharge efficiency. Furthermore, since the spiral shaftless paddle 2 has no central shaft, it effectively prevents material accumulation and entanglement on the shaft. This design significantly reduces equipment failure rates, improves equipment reliability and stability, reduces maintenance costs and downtime, and increases production efficiency.
