Description

Technical Field

[0001] This utility model relates to the field of beverage packaging technology, and in particular to a dust-proof koji powder weighing and filling device. Background Technology

[0002] The koji-making process is a core part of winemaking, encompassing raw material processing, koji shaping, fermentation in the koji room, drying and aging, and pulverizing and bottling. Essentially, it involves the enrichment and cultivation of microorganisms to prepare the koji, providing a complex enzyme system and flavor compounds for subsequent saccharification and fermentation. In the koji-making process, the koji powder serves as the core carrier for microbial fermentation, and its precise bottling is a crucial step determining the stability of the subsequent brewing process.

[0003] Originally, the koji powder filling process used a koji powder packaging machine to meter and fill bagged koji powder. Later, due to the increased demand for filling koji hoppers, a movable screw conveyor was used at the packaging machine's discharge port to transport the koji powder into the hoppers. The koji powder has a fine texture and high particle size. During the filling process, due to the lack of effective sealing and dust prevention measures at the connection between the screw conveyor and the koji hopper, the koji powder was severely scattered, generating a large amount of dust. This severe koji powder scattering not only wastes materials and makes it impossible to accurately control the filling volume, affecting the standardization and stability of subsequent brewing processes, but also pollutes the working environment, seriously deviating from occupational health standards and endangering the health of operators. Furthermore, the scattered koji powder may adhere to the surface of production equipment, affecting its normal operation and increasing equipment maintenance costs.

[0004] Therefore, it is necessary to design a dust-proof koji powder weighing and filling device to reduce koji powder flying, improve weighing accuracy, and improve the on-site working environment. Utility Model Content

[0005] To address the aforementioned problems, this utility model discloses a dust-proof koji powder weighing and filling device, which can achieve a sealed connection with the koji hopper and dust prevention measures during filling, effectively reducing dust emissions and improving weighing accuracy.

[0006] The specific plan is as follows:

[0007] A dust-proof koji powder weighing and filling device includes a first temporary storage bin, a first screw conveyor, a second temporary storage bin, a second screw conveyor, and a discharge temporary storage bin connected in sequence. The inlet of the first temporary storage bin is connected to the discharge port of the koji powder elevator. The inlet of the first screw conveyor is connected to the discharge port of the first temporary storage bin. The inlet of the second temporary storage bin is connected to the discharge port of the first screw conveyor. The inlet of the second screw conveyor is connected to the discharge port of the second temporary storage bin. The inlet of the discharge temporary storage bin is connected to the discharge port of the second screw conveyor. A weighing sensor for weighing the koji powder in the discharge temporary storage bin is installed below the discharge temporary storage bin. A discharge butterfly valve for controlling the discharge of koji powder is connected to its discharge port.

[0008] Furthermore, the lower end of the discharge butterfly valve is connected to the feed inlet of the curved bucket via a telescopic hose.

[0009] Furthermore, the upper end of the telescopic hose is connected to the discharge butterfly valve, and the lower end has a flared structure that is wider at the top and narrower at the bottom, and is snapped into the feed inlet of the curved bucket to form an effective sealing connection, which can meet the feeding needs of curved buckets of different heights.

[0010] Furthermore, the telescopic flexible hose consists of an inner tube and an outer tube, wherein the inner tube is used for conveying the powder, and the outer tube is connected to a dust removal pipe for absorbing the dust that overflows during the feeding process.

[0011] The beneficial effects of this utility model are as follows:

[0012] 1. The length of the telescopic hose is adjustable to meet the material feeding needs of hoppers of different heights; its lower end extends into the feed inlet of the hopper to form an effective sealed connection; the whole adopts an inner and outer layer design, with the inner tube conveying the powder and the outer tube connecting to the dust removal pipe, forming a double dust prevention mechanism with the sealing structure, effectively suppressing dust leakage.

[0013] 2. A weighing sensor is used to weigh the koji powder in the feeding temporary storage bin, and the weight of the koji powder is monitored in real time. Quantitative filling is achieved by opening and closing the feeding butterfly valve. When the set weight is reached, the feeding butterfly valve opens to carry out the koji powder feeding and transmission, which effectively improves the filling accuracy of the koji powder.

[0014] 3. The overall layout adopts a segmented design with multi-stage temporary storage bins and screw conveyors (first temporary storage bin → first screw conveyor → second temporary storage bin → second screw conveyor → discharge temporary storage bin), which can effectively reduce the risk of powder blockage and improve the stability of the equipment operation.

[0018] The present invention will be further explained below with reference to the accompanying drawings and specific embodiments. It should be understood that the following specific embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention.

[0019] like Figure 1As shown, the present invention provides a dust-proof koji powder weighing and filling device, comprising a first temporary storage bin 1, a first screw conveyor 2, a second temporary storage bin 3, a second screw conveyor 4, and a discharge temporary storage bin 5 connected in sequence. The inlet of the first temporary storage bin 1 is connected to the discharge port of the koji powder elevator, the inlet of the first screw conveyor 2 is connected to the discharge port of the first temporary storage bin 1, the inlet of the second temporary storage bin 3 is connected to the discharge port of the first screw conveyor 2, the inlet of the second screw conveyor 4 is connected to the discharge port of the second temporary storage bin 3, and the inlet of the discharge temporary storage bin 5 is connected to the discharge port of the second screw conveyor 4. A weighing sensor 6 for weighing the koji powder in the discharge temporary storage bin 5 is provided below the discharge temporary storage bin 5, and a discharge butterfly valve 7 for controlling the discharge of koji powder is connected to its discharge port.

[0020] In this embodiment, the lower end of the discharge butterfly valve 7 is connected to the feed inlet of the curved bucket via a telescopic hose 8. The upper end of the telescopic hose 8 is connected to the discharge butterfly valve 7, and the lower end has a trumpet-shaped structure that is wider at the top and narrower at the bottom, and it is snapped into the feed inlet of the curved bucket to form an effective sealing connection, which can meet the feeding requirements of curved buckets of different heights. The telescopic hose 8 consists of an inner tube and an outer tube, wherein the inner tube is used for conveying the powder, and the outer tube is connected to the dust removal pipe 9 to suck up the dust overflowing during the feeding process.

[0021] Before filling the koji powder, first place the koji hopper in the designated position and lower the telescopic hose 8 until it partially reaches the koji hopper's feed inlet to form an effective seal. Simultaneously, start the dust removal system. Then, start the crushing and feeding system. The koji powder is lifted by the elevator and sequentially transported through the first temporary storage bin 1, the first screw conveyor 2, the second temporary storage bin 3, and the second screw conveyor 4 to the discharge temporary storage bin 5. The weighing sensor 6 monitors the weight of the koji powder in the discharge temporary storage bin 5. When the weight reaches the set value, the second screw conveyor 4 shuts off to stop feeding, and the discharge butterfly valve 7 opens. The koji powder in the discharge temporary storage bin 5 is then transported to the koji hopper through the telescopic hose 8, while the initial koji powder is temporarily stored in the second temporary storage bin 3 and the first temporary storage bin 1. After the koji powder in the discharge temporary storage bin 5 has been completely transported, the discharge butterfly valve 7 closes, and the second screw conveyor 4 starts to replenish the koji powder. This cycle repeats, achieving dust-free koji powder weighing and filling.

[0022] The technical means disclosed in this utility model are not limited to those disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications are also considered within the scope of protection of this utility model.
