Thus, features defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0022] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. Example:

[0023] This utility model provides a screw conveyor for black tea powder, used to clean the inside of the conveyor after material conveying, improving the cleanliness of the device and avoiding long-term operation that could affect product quality and equipment operation. To achieve the structural function of the device, it includes a screw conveyor 1, a support 4, and a first drive device 9. The screw conveyor 1 includes a conveying trough 101 for storing powdered or granular materials, which can be U-shaped or a closed annular shape. To push the material, a spiral blade 102 is rotatably mounted inside the conveying trough 101 to push the material along its extension direction. The support 4 supports the screw conveyor 1, and a motor 103 is mounted on the support 4 to drive the spiral blade 102 to rotate, thus providing power for material conveying. The two sides of the conveying trough 101 are... The equipment is equipped with an inlet 2 and an outlet 3 to allow materials to be fed into the equipment or to be output in a stable position. The inlet 2 opens upwards, and the outlet 3 opens downwards. To facilitate cleaning of the equipment, an opening slot is provided below the conveying pipe 101, positioned between the inlet 2 and the outlet 3. This allows materials that are difficult to remove from the trough to be discharged directly through the opening slot, thus facilitating the cleaning process. To maintain normal material conveying, a filling plate 10 is provided at the opening slot. The first driving device 9 is used to drive the filling plate 10 to close or open the opening slot, corresponding to the working or cleaning state. During operation, it is necessary to ensure that the inner arc surface of the filling plate 10 matches the arc surface of the inner wall of the conveying pipe 101 to ensure unobstructed material conveying. Through the above structural design, in addition to normal operation, the device can also facilitate the cleaning of the spiral blades 102 and impurities in the groove by opening the slot. In addition, by shortening the gap between the filler plate 10 and the spiral blades 102, the impurities adhering to the spiral blades 102 can be squeezed out or scraped off by physical compression, which can further reduce the burden of manual cleaning. Compared with traditional spiral conveyors, it is more conducive to cleaning, ensures the quality of conveyed products when used again, and reduces the impact on equipment operation.

[0024] This embodiment of the utility model provides a screw conveyor for black tea powder. Considering the need for convenient removal of waste residue inside the conveying trough 101 and to facilitate transportation at different heights, a support platform 6 can be rotatably mounted on the bracket 4. Figure 1 and Figure 3As shown, the screw conveyor 1 is fixedly installed on the support platform 6, and the second drive device 5 is also fixedly installed on the bracket 4. A connecting plate 7 is fixedly installed below the support platform 6, and the connecting plate 7 is connected to the output end of the second drive device 5. The second drive device 5 is used to drive the connecting plate 7 to rotate the support platform 6 along the rotation axis of the support platform 6, so that one end of the conveying trough 101 can be raised or lowered. When the conveying trough 101 is raised or lowered, the material inside it will also fall down following the guiding direction of the screw blade 102. When passing through the opening groove, the detached adhesive will also fall through the opening groove, which is conducive to adjusting the angle of the equipment according to the usage requirements, so as to facilitate cleaning. In addition, by adjusting the height position, it is also convenient to convey materials at different heights.

[0025] This embodiment of the utility model provides a screw conveyor for black tea powder. To facilitate the fixing of the first drive device 9, at least two clamps 11 can be installed on the conveying pipe 101. Figure 1 As shown, a mounting plate 12 is connected between two or more clamps 11. The first drive device 9 can follow the screw conveyor 1 by being fixedly mounted on the mounting plate 12. The first drive device 9 can be a cylinder or other servo drive method; the specific implementation is not limited here. Considering that the filling plate 10, being relatively long, is prone to swaying and tilting in areas of high torque when a single drive mechanism drives the filling plate 10, resulting in gaps, several linear bearings are provided on the mounting plate 12 to reduce the impact of these gaps. Several sliding shafts 13, which can slidably insert into the linear bearings, are also installed on the filling plate 10, allowing the filling plate 10 to move along the sliding shafts 13, thus limiting the movement of the filling plate 10 itself.

[0026] This utility model provides a screw conveyor for black tea powder. To facilitate cleaning, water can be used to soften and remove clumps of impurities. Therefore, the conveying trough 101 has a circular cross-section and an inlet pipe 15 is installed on it. The outlet of the inlet pipe 15 is connected to the inner cavity of the conveying trough 101, allowing the conveying trough 101 to be softened and cleaned with cleaning fluid. To prevent water loss, the conveying trough 101 can be tilted to retain a certain amount of water, preventing direct discharge from the outlet 3. To prevent long-term water retention, in addition to opening the filling plate 10 for sufficient drainage, an air inlet pipe 16 is also installed on the conveying trough 101. The outlet of the air inlet pipe 16 is connected to the inner cavity of the conveying trough 101, thereby accelerating the airflow inside the conveying trough 101, thus accelerating the drying of moisture and the removal of water mist, which helps reduce the impact of corrosion. To facilitate control of the two pipe inputs, a common pipe 14 connected to the inner cavity of the conveying pipe 101 can be installed on the conveying pipe 101. Liquid or gas can enter through the common pipe 14 interface. For this purpose, both the liquid inlet pipe 15 and the gas inlet pipe 16 can be connected to the common pipe 14 and a solenoid valve 17 can be installed on both the liquid inlet pipe 15 and the gas inlet pipe 16 to control the corresponding passage. The two solenoid valves 17 cannot be in the open state at the same time. When the equipment is conveying materials normally, both solenoid valves 17 should be in the closed state at the same time.

[0027] This utility model provides a screw conveyor for black tea powder. In order to make the length of the screw blade 102 adaptable to the size of different equipment, the screw blade 102 can be configured to be composed of multiple splicing sections, so that its length can be adjusted according to actual use requirements. The adjacent splicing sections are connected by connecting pieces 8 to ensure that the connected screw blades can be smoothly transitioned and to avoid gaps that affect the normal conveying of powder materials.

[0028] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
