[0002] The storage technology of powder materials is widely applied. Especially in the brewing process, koji powder is an important raw material. The koji powder required for brewing is generally produced in the koji-making workshop and then transported to the winemaking workshop for use. The traditional storage device is usually a temporary storage tank set outside the workshop, and it is output for use through a screw conveyor. In this operation mode, the koji powder will have residues or adhesions in the pipeline. In addition, the temporary storage tank and the pipeline are exposed to the sun, and these factors will have a certain impact on the changes in the temperature and humidity of the koji powder. At the same time, the investment, operation and maintenance costs of this method are relatively high.

[0003] Therefore, in the prior art, a mobile storage device has emerged. The koji powder can be stored in a suitable environment through the mobile storage device, and when using the koji powder, the storage device is moved to the required position. It can avoid the influence of environmental factors on the quality of the koji powder, and the cost of the storage device is relatively low and it is convenient to use.

[0004] However, the structure of the existing mobile storage device is simple. There is only a fixed feed inlet at the top of its storage bin. When storing koji powder into the storage bin through the feed inlet, the koji powder is likely to accumulate directly below the feed inlet, while there are still blank parts in other parts of the storage bin that are not filled, resulting in the storage space in the storage bin not being fully utilized, affecting the storage capacity of the storage bin and causing waste of resources.

[0027] As Figures 1 to 3 shown, this embodiment provides a powder temporary storage device, including a frame 10, a storage bin 20, a feeding assembly, a discharging assembly and a dust collector 50.

[0028] The frame 10 of this embodiment plays a supporting role, and the storage bin 20 is fixedly arranged inside the frame 10. The bottom of the frame 10 is provided with rollers 12 to facilitate the movement of the powder temporary storage device. A braking mechanism can be selectively arranged on the rollers 12 so that the powder temporary storage device stays at the required position. The side of the frame 10 is also preferably provided with a handrail 11 to facilitate the flexible movement of the powder temporary storage device by manual pushing.

[0029] At the top of the storage bin 20 of this embodiment, a strip-shaped opening is provided. At the bottom of the storage bin 20, a discharge port 21 is provided. The discharge port 21 is preferably in a conical shape that gradually contracts downward to facilitate the koji powder to leave the storage bin 20. The number of the discharge ports 21 in this embodiment is preferably two, and the two discharge ports 21 are evenly arranged at the bottom of the storage bin to facilitate the koji powder at different positions of the storage bin 20 to be discharged through the nearby discharge port 21. It should be noted that this embodiment can also be provided with more than two discharge ports 21 according to requirements, which will not be elaborated in this embodiment.

[0030] The feeding assembly of this embodiment is arranged above the storage bin 20 for feeding koji powder into the storage bin 20. The feeding assembly includes a cover plate 30 and a feeding port 32. The cover plate 30 is covered above the strip-shaped opening, and the cover plate 30 can move longitudinally along the strip-shaped opening relative to the storage bin 20. The feeding port 32 is arranged on the cover plate 30, and the feeding port 32 penetrates the upper and lower surfaces of the cover plate 30 to communicate with the inside of the storage bin 20. It should be noted that the length and width of the cover plate 30 in this embodiment are both greater than the length and width of the strip-shaped opening to ensure that the cover plate 30 can cover the strip-shaped opening. The feeding port 32 in this embodiment is located inside the contour of the strip-shaped opening to prevent the strip-shaped opening from interfering with the koji powder entering the storage bin 20 through the feeding port 32.

[0031] Since the cover plate 30 of this embodiment is movable, the feeding port 32 can move with the cover plate 30 to different positions of the storage bin 20. When it is necessary to store koji powder in the storage bin 20, first move the cover plate 30 to make the feeding port 32 move to a certain position at the top of the storage bin 20, and the koji powder accumulates directly below this position through the feeding port 32; when the height of the accumulated koji powder approaches the feeding port 32, then move the feeding port 32 to another position to make the koji powder accumulate directly below this position. Repeatedly moving the feeding port 32 can ensure that the storage space of the storage bin 20 is fully filled with koji powder and improve the utilization rate of the storage space.

[0032] The feeding assembly of this embodiment further includes guide rails 33. The guide rails 33 are fixedly arranged at the top of the storage bin 20, and both sides of the cover plate 30 are movably connected to the corresponding guide rails 33, so that the guide rails 33 guide the cover plate 30 to move longitudinally to ensure smooth movement of the cover plate 30. The two ends of the cover plate 30 in this embodiment extend out of the corresponding ends of the guide rails 33, and the two ends of the cover plate 30 form flanges 31 that tilt upward, which are convenient for gripping to push the cover plate 30 to move.

[0033] The discharge assembly of this embodiment includes a discharge valve 40 provided at the discharge port 21. By opening and closing the discharge valve 40, the discharge port 21 is opened and closed, thereby controlling the discharge of koji powder. The discharge valve 40 of this embodiment is preferably a slide gate valve, which includes a housing and a slide plate. The slide plate is fixedly connected to the discharge port 21 and is movably inserted into the housing. By moving the slide plate, the discharge port 21 can be opened and closed. The slide gate valve can prevent the koji powder from clogging the discharge port 21. Its specific structure and principle are prior art and will not be elaborated in this embodiment.

[0034] The dust collector 50 of this embodiment is provided on the side wall of the storage bin 20 and near the top. Since the storage bin 20 is in a sealed state, negative pressure and pressure increase phenomena will occur inside the storage bin 20. By using the dust collector 50 to balance the air pressure inside the storage bin 20, it is possible to avoid the dust leakage during the feeding and discharging of the powder material. The number of dust collectors 50 is preferably corresponding to the number of discharge ports 21, and the dust collectors 50 are correspondingly arranged above the discharge ports 21 for convenient dust collection. It should be noted that the dust collector 50 of this embodiment is prior art. For example, in some embodiments of the dust collector 50, a filter element is provided to prevent dust leakage, and in some embodiments of the dust collector 50, a vibrating member is provided to prevent dust from adhering to the filter element. The specific structure of the dust collector 50 will not be elaborated in this embodiment.

[0035] The technical features of the above embodiments can be combined arbitrarily. For the sake of concise description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

[0036] The above-described embodiments merely represent several implementation manners of the present invention. The description is relatively specific and detailed, but it should not be construed as a limitation to the scope of the utility model patent. It should be pointed out that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the utility model patent shall be subject to the appended claims.
