Description

Technical Field

[0001] This utility model relates to the field of flour processing technology, and in particular to a flour screening device for flour processing. Background Technology

[0002] As the basic raw material for noodle processing, the fineness and uniformity of flour particles directly affect the taste, texture, and processing performance of noodle products. Therefore, in the noodle production process, flour usually needs to be screened to remove large impurities, lumps, or insufficiently broken particles to ensure that the flour quality meets production requirements.

[0003] Currently, most flour sorting devices on the market use fixed screen structures or single-layer rotating filter cylinder structures, and their working principle is mainly to achieve grading by vibrating the flour. However, these traditional devices have the following obvious drawbacks in practical applications:

[0004] 1. In traditional sieving devices, the filter cylinder or screen usually bears the entire weight of the flour. When the amount of flour fed at one time is too large, the accumulation of flour will put enormous pressure on the bottom of the filter cylinder (especially the central area), causing the filter cylinder to deform, the filter holes to become clogged, and even the screen to break.

[0005] 2. Insufficient screening efficiency and effect: The effective screening area of ​​a single-layer screen or filter cylinder is limited, and the contact area between flour particles and filter holes is insufficient, which easily leads to insufficient screening, with fine powder remaining in the coarse material or excessive screening time. Utility Model Content

[0006] The purpose of this invention is to address the problems existing in the background technology by proposing a flour screening device for noodle processing.

[0007] The technical solution of this utility model is a flour screening device for noodle processing, comprising:

[0008] The outer box is foldable, with a funnel connected to its top and a second discharge pipe connected to its bottom.

[0009] The filter cartridge assembly has a first discharge pipe connected to its bottom end. The first discharge pipe is rotatably mounted on the bottom of the folded outer box and passes through the bottom end of the folded outer box. The filter cartridge assembly is equipped with a power component for driving the first discharge pipe to rotate.

[0010] Hollow shell, the hollow shell is located inside the filter cartridge assembly, the upper end of the hollow shell has a conical structure, and multiple telescopic rod assemblies are connected between the hollow shell and the top of the folded outer box;

[0011] The sealing assembly includes a sealing plate, a movable rod, and a limiting plate. The movable rod is vertically installed inside the folding outer box, and its upper and lower ends are connected to the limiting plate and the sealing plate, respectively. The sealing plate is movably installed inside the first discharge pipe. A bracket is installed at the top of the folding outer box, and the movable rod movably passes through the bracket.

[0012] Preferably, the folding outer case includes a top cover, a bottom plate, and a folding tube. The top cover is located directly above the bottom plate, and the folding tube is connected between the top cover and the bottom plate. The upper part of the bottom plate has a funnel structure, and multiple support legs are provided at the bottom end of the bottom plate. A support and adjustment assembly is connected between the top cover and the bottom plate.

[0013] Preferably, the support adjustment assembly includes a plurality of first sleeves, which are coaxially arranged. The outermost first sleeve and the innermost first sleeve are respectively connected to the bottom plate and the top cover. The upper inner end and the lower outer end of the first sleeve are provided with threads.

[0014] Preferably, the filter cartridge assembly includes a filter plate and multiple filter cartridges. The filter plate and multiple filter cartridges are provided with several filter holes. The multiple filter cartridges are coaxially arranged. Two adjacent filter cartridges on the inner and outer sides are slidably connected in the vertical direction. The filter plate is connected to the bottom end of the innermost filter cartridge. The upper end of the outermost filter cartridge is connected to a rotating ring. A fixed ring is connected to the inner wall of the top cover. The rotating ring is rotatably mounted on the fixed ring. The upper end of the filter plate has a funnel structure.

[0015] Preferably, the telescopic rod assembly includes a plurality of second sleeves, which are coaxially arranged. Two adjacent second sleeves are slidably connected in the vertical direction. The outermost second sleeve is connected to the hollow shell, while the innermost second sleeve is connected to the top cover.

[0016] Preferably, the power assembly includes a servo motor, a gear, and a gear ring. The servo motor is mounted on the base plate, the gear is mounted on the output shaft of the servo motor, and the gear ring is mounted on the outer periphery of the first discharge pipe. The gear and the gear ring are meshed together.

[0017] Compared with the prior art, the present invention has the following beneficial technical effects:

[0018] 1. A hollow, conical shell is positioned at the center of the filter cartridge assembly, suspended below the top cover by a retractable second sleeve assembly. When the amount of material fed at one time is too large, the weight of the flour accumulated in the central area of ​​the filter cartridge will partially act on the conical surface and sidewalls of the hollow shell, forming effective internal support. This significantly reduces the direct pressure of the flour on the filter cartridge assembly below, effectively preventing deformation, filter pore blockage, or even damage caused by excessive instantaneous load. This improves the load-bearing capacity and service life of the equipment, ensuring continuous and stable screening operations.

[0019] 2. The design adopts a coaxial multi-layer nested rotating filter cylinder assembly. The power component consisting of a servo motor, gears and gear rings drives the entire filter cylinder assembly to rotate synchronously. The centrifugal force, gravity and flour tumbling between the multi-layer filter cylinders generated by the rotation greatly improve the contact opportunity and throughput efficiency between flour particles and filter holes, resulting in more thorough, uniform and fast screening.

[0024] Example 1

[0025] like Figures 1-3 As shown in the figure, the flour screening device for noodle processing proposed in this embodiment includes a folded outer box, a filter cylinder assembly, a hollow shell 9, and a sealing assembly.

[0026] The top of the folding outer box is connected to a funnel 4, and the bottom of the funnel is connected to a second discharge pipe 7.

[0027] The bottom end of the filter cartridge assembly is connected to a first discharge pipe 6. The first discharge pipe 6 is rotatably mounted on the bottom of the folded outer box and passes through the bottom end of the folded outer box. The filter cartridge assembly is equipped with a power component for driving the first discharge pipe 6 to rotate. The power component includes a servo motor 81, a gear 82 and a gear ring 83. The servo motor 81 is mounted on the base plate 2, the gear 82 is mounted on the output shaft of the servo motor 81, and the gear ring 83 is mounted on the outer periphery of the first discharge pipe 6. The gear 82 and the gear ring 83 are meshed and connected.

[0028] The hollow shell 9 is located inside the filter cartridge assembly. The upper end of the hollow shell 9 has a conical structure. Multiple telescopic rod assemblies connect the hollow shell 9 to the top of the folded outer box.

[0029] The sealing assembly includes a sealing plate 10, a movable rod 11, and a limiting plate 12. The movable rod 11 is vertically arranged inside the folding outer box. The upper and lower ends of the movable rod 11 are connected to the limiting plate 12 and the sealing plate 10, respectively. The sealing plate 10 is movably arranged inside the first discharge pipe 6. A bracket 13 is provided at the top of the folding outer box, and the movable rod 11 movably passes through the bracket 13.

[0030] The steps for sifting flour in this technical solution are as follows:

[0031] Feeding: The flour to be screened is fed into the filter cylinder assembly located in the central area of ​​the device through the funnel 4 at the top of the device.

[0032] Power start: Start the servo motor 81 to work. The servo motor 81 drives the gear 82 on its output shaft to rotate. The gear 82 meshes with the gear ring 83 installed on the outer periphery of the first discharge pipe 6. Since the gear ring 83 is fixedly connected to the first discharge pipe 6, the rotation of the gear 82 drives the gear ring 83 and the first discharge pipe 6 to rotate synchronously. The first discharge pipe 6 then drives the filter cartridge assembly to rotate.

[0033] Screening process: The rotating filter cylinder assembly includes filter plates 20 and all filter cylinders 15 with filter holes evenly distributed on them. Under the action of centrifugal force, gravity and continuous tumbling generated by the rotation, qualified flour particles smaller than the filter hole diameter are screened out through the filter holes.

[0034] Qualified flour collection and discharge: Qualified flour passing through the filter holes of the filter cylinder assembly falls into the internal space of the folded outer box. The collected qualified flour naturally slides down and gathers at the center bottom of the folded outer box. The qualified flour is finally discharged through the second discharge pipe 7 connected to the bottom end of the bottom plate 2, and the flour enters the downstream collection container or process.

[0035] Temporary storage and discharge of large particle impurities and unqualified flour lumps: Large particle impurities that cannot pass through the filter holes, such as insufficiently broken flour lumps, agglomerates, or a small amount of foreign matter mixed in, will remain inside the rotating filter cartridge assembly. During normal screening, the sealing plate 10 located inside the first discharge pipe 6 is in a "closed" state, usually kept in a low position by its own weight or simple limiting, preventing impurities from falling directly. When it is necessary to clean the impurities, the operator pulls the movable rod 11 upward. The movable rod 11 is set vertically. Pulling the movable rod 11 upward will drive the sealing plate 10 to move upward, away from its sealed position, opening the inner cavity channel of the first discharge pipe 6. At this time, the large particle impurities accumulated inside the filter cartridge assembly, mainly on the funnel structure of the filter plate 20, fall down and are discharged along the opened first discharge pipe 6 under the action of gravity. After the discharge is completed, the movable rod 11 is released, and the sealing plate 10 falls back under the action of gravity, re-sealing the first discharge pipe 6, and the screening work can continue.

[0036] Support function of the hollow shell: The hollow shell 9 is located inside the filter cartridge assembly. Its upper end is a conical structure. The hollow shell 9 is suspended below the top cover 1 by multiple telescopic rod assemblies consisting of multiple coaxially nested second sleeves 14 that can slide relative to each other in the vertical direction. In the initial state, there is a gap between the hollow shell 9 and the bottom of the inner cavity of the filter cartridge assembly. When the amount of flour added to the filter cartridge assembly at one time is too large, the height of the flour accumulation may increase significantly. At this time, the conical upper end and side of the hollow shell 9 located in the center can effectively support or hold the flour accumulated in the central area, which significantly reduces the direct pressure of the flour weight on the filter cartridge assembly below, especially the bottom filter plate 20, preventing the filter cartridge assembly from deforming or being damaged due to overload, ensuring screening efficiency and equipment life, and improving the driving efficiency of the power component.

[0037] Example 2

[0038] like Figures 1-4 As shown in the figure, the flour screening device for noodle processing proposed in this embodiment, compared with the first embodiment, in this embodiment, the folding outer box includes a top cover 1, a bottom plate 2 and a folding soft tube 3. The top cover 1 is located directly above the bottom plate 2. The folding soft tube 3 is connected between the top cover 1 and the bottom plate 2. The upper end of the bottom plate 2 is a funnel structure. Multiple support legs 18 are provided at the bottom end of the bottom plate 2. A support adjustment component is connected between the top cover 1 and the bottom plate 2.

[0039] The support adjustment assembly includes multiple first sleeves 5, which are coaxially arranged. The outermost first sleeve 5 and the innermost first sleeve 5 are respectively connected to the base plate 2 and the top cover 1. The upper inner end and the lower outer end of the first sleeve 5 are provided with threads 19.

[0040] The filter cartridge assembly includes a filter plate 20 and multiple filter cartridges 15. The filter plate 20 and multiple filter cartridges 15 are provided with several filter holes. The multiple filter cartridges 15 are coaxially arranged. Two adjacent filter cartridges 15 on the inner and outer sides are slidably connected in the vertical direction. The filter plate 20 is connected to the bottom end of the innermost filter cartridge 15. The upper end of the outermost filter cartridge 15 is connected to a rotating ring 17. A fixed ring 16 is connected to the inner wall of the top cover 1. The rotating ring 17 is rotatably mounted on the fixed ring 16. The upper end of the filter plate 20 has a funnel structure.

[0041] The telescopic rod assembly includes multiple second sleeves 14, which are coaxially arranged. Two adjacent second sleeves 14 are slidably connected in the vertical direction. The outermost second sleeve 14 is connected to the hollow shell 9, while the innermost second sleeve 14 is connected to the top cover 1.

[0042] The core advantage of this device lies in its foldability, which greatly saves storage and transportation space when not in operation. The folding process mainly involves the coordinated shrinking of the outer casing and filter cartridge assembly. The specific operation method is as follows:

[0043] Lowering the height of the folded outer casing: When the device needs to be stored, the operator applies external force, and the support adjustment assembly consists of multiple coaxially nested first sleeves 5. The outermost first sleeve 5 is connected to the base plate 2, and the innermost first sleeve 5 is connected to the top cover 1; each first sleeve 5 has threads 19 on its inner upper end and outer lower end. Figure 4 The diagram illustrates the connection between adjacent first sleeves 5. These threaded structures allow axial expansion and contraction between adjacent first sleeves 5 through relative rotation. By rotating each one sequentially, all adjacent first sleeves 5 are screwed into each other, resulting in a reduction in the overall height of the support adjustment assembly. This reduction process forces the top cover 1 closer to the bottom plate 2. This structure is the same as the threaded connection structure between a bottle cap and the bottle neck. During contraction, the outer thread 19 is rotated to a position below the inner thread 19. At this time, the inner first sleeve 5 can move freely inside the outer first sleeve 5 due to the release of the limiting effect. The folding soft tube 3 connected between the top cover 1 and the bottom plate 2 is usually made of flexible, stretchable corrugated material. It undergoes compression deformation as the top cover 1 moves downward, and the folds are compressed, thereby allowing a significant reduction in the overall height of the folding outer box.

[0044] Synchronous folding of the filter cartridge assembly: The folding of the filter cartridge assembly and the retraction of the outer casing are linked and do not require separate operation. When the top cover 1 moves downward under the shortening action of the support adjustment assembly, the fixed ring 16 also moves downward. The fixed ring 16 drives the rotating ring 17 that it cooperates with to move downward together. The rotating ring 17 then drives the outermost filter cartridge 15 connected to it to move downward. Since the inner and outer adjacent filter cartridges 15 are slidably connected in the vertical direction, for example, the outer wall of the inner filter cartridge has a slider and the inner wall of the outer filter cartridge has a corresponding groove, when the outermost filter cartridge 15 is pulled downward, its bottom end will contact and push the inner adjacent filter cartridge 15 to slide downward. When this inner filter cartridge 15 moves downward, its bottom end will contact and push the next innermost filter cartridge 15 to slide down. This process is transmitted step by step. All the filter cartridges 15 are stacked together, and the overall height of the filter cartridge assembly is reduced to the minimum.

[0045] The telescopic rod assembly and the hollow shell follow each other: The telescopic rod assembly connecting the hollow shell 9 and the top cover 1 has multiple nested second sleeves 14 that are designed to be telescopic. When the top cover 1 moves down, it forces all the nested second sleeves 14 to slide and contract relative to each other in sequence. This causes the hollow shell 9, which is suspended at the end of the telescopic rod assembly, to also move down and remain in the internal center position of the filter cartridge assembly after it has contracted, thus avoiding interference.

[0046] After folding, the height of the folded outer box, the height of the filter cartridge assembly, and the length of the telescopic rod assembly are all at their minimum volume, greatly saving space.

[0047] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
