Detailed Embodiments

[0017] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which this application belongs; the terms used in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application; the terms "including" and "having" and any variations thereof in the specification and claims of this application and the above description of the drawings are intended to cover non-exclusive inclusion. The terms "first", "second", etc. in the specification and claims of this application or the above drawings are used to distinguish different objects and not to describe a specific order.

[0018] Reference to "embodiment" herein means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of this application. The phrase appears in various places in the specification and does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. Those skilled in the art will explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments.

[0019] An embodiment of the present utility model provides a raw material mixer, asFigures 1-4 As shown in the figure, it includes a mixing drum 1 and a controller. The upper surface of the mixing drum 1 is fixedly connected with an equipment frame 2, and the upper surface of the equipment frame 2 is fixedly connected with a mixing motor 3. The output end of the mixing motor 3 is fixedly connected with a rotating shaft 5, and the outer wall of the lower end of the rotating shaft 5 is fixedly connected with a mixing rod 6. An inner cavity 7 is opened in the rotating shaft 5, and a cleaning water spraying hole communicating with the inner cavity 7 is opened on the outer wall of the rotating shaft 5. A communication hole 8 communicating with the inner cavity 7 is opened on the outer wall of the upper end of the rotating shaft 5, and a water inlet pipe 4 is communicated with the outer wall of the equipment frame 2. The mixing motor 3 is electrically connected with the controller.

[0020] It should be noted that due to the fact that the existing sealed mixer is not easy to open inside, resulting in difficult internal cleaning. Therefore, to solve the problem that the existing sealed mixer is not easy to open inside, resulting in difficult internal cleaning, in this solution, when it is necessary to clean the inside of the mixing drum 1, the water inlet pipe 4 is connected to a high-pressure water pump. Through the operation of the high-pressure water pump, the water inlet pipe 4 injects water into the equipment frame 2 and the inner cavity 7, so that the cleaning water spraying holes on the rotating shaft 5 spray water to clean the inner wall of the mixing drum 1. Driven by the output end of the mixing motor 3, the rotating shaft 5 starts to rotate, so that the cleaning water spraying holes can rotate, improving the working range of the cleaning water spraying holes and ensuring the comprehensiveness of the cleaning of the inner wall of the mixing drum 1.

[0021] In a further preferred embodiment of the present invention, as Figure 2 and Figure 2 shown, an electric hydraulic rod 10 is fixedly connected to the lower surface of the equipment frame 2, and a slider 11 is fixedly connected to the telescopic end of the electric hydraulic rod 10. A fixing plate 12 is fixedly connected to the outer wall of the rotating shaft 5, and a shielding ring 13 matching the cleaning water spraying holes is sleeved on the outer wall of the rotating shaft 5. The shielding ring 13 is fixedly connected to the fixing plate 12, and a circular chute matching the slider 11 is opened on the lower surface of the fixing plate 12.

[0022] In this embodiment, the powdered raw materials will cause blockage of the cleaning water spraying holes. When not cleaning, the cleaning water spraying holes are shielded by the shielding ring 13 to prevent the powdered raw materials from blocking the cleaning water spraying holes. When cleaning is required, through the extension of the telescopic end of the electric hydraulic rod 10, the shielding ring 13 can be separated from shielding the cleaning water spraying holes, ensuring the normal operation of the cleaning water spraying holes. The slider 11 can slide in the circular chute on the fixing plate 12.

[0023] In a further preferred embodiment of the present invention, as Figure 4 shown, a baffle 9 is fixedly connected to the inner wall of the equipment frame 2.

[0024] In a further preferred embodiment of the present invention, as Figure 1 shown, a drain pipe 14 is communicated with the outer wall of the equipment frame 2.

[0025] In a further preferred embodiment of the present utility model, as Figure 4 shown, an electric control valve 15 is provided inside the drain pipe 14, and the electric control valve 15 is electrically connected to the controller.

[0026] In this embodiment, since the electric control valve 15 is electrically connected to the controller, and the controller controls the electric control valve 15 to open, after the equipment cleaning is completed, the accumulated liquid in the equipment frame 2 can be discharged through the drain pipe 14, preventing the accumulated liquid in the equipment frame 2 from leaking into the mixing drum 1 through the gap between the equipment frame 2 and the rotating shaft 5 and causing pollution of the raw materials. Through the baffle 9, the height of the gap between the rotating shaft 5 and the equipment frame 2 is increased, further avoiding the leakage of the accumulated liquid in the equipment frame 2 into the mixing drum 1 through the gap between the equipment frame 2 and the rotating shaft 5.
