Description

Technical Field

[0001] This utility model relates to the technical field of flour screening equipment, specifically a screening device for flour processing. Background Technology

[0002] Flour may clump during transportation and storage. Screening can remove these clumps, making the flour finer and more uniform. Flour screening is an important step in improving flour quality, as it can remove clumps and impurities, ensuring that the flour is fine and uniform.

[0003] An investigation revealed that a utility model patent (publication number: CN221619996U) discloses a high-precision flour screening device for flour processing. The device includes two support plates, with a screening frame positioned between them. Two pillars are fixedly mounted on the outer walls of each side of the screening frame. Each support plate has a through hole for the pillars to slide through. The two pillars on the same side are connected to a common connecting plate at one end of the support plate. A vibration motor is fixedly mounted on one of the connecting plates. A connecting rod is fixedly mounted between the two support plates, and two U-shaped frames are fixedly mounted on the connecting rod. Support rods are fixedly mounted at the bottom of each U-shaped frame, and material dispersing rods are mounted at the bottom of the support rods. The vibration motor drives the connecting plate to vibrate left and right, screening the flour in the screening frame through the filter screen. This vibration screening method reduces flour clumping and labor costs. Multiple material dispersing rods further disperse the flour in the screening frame, preventing it from piling up and improving screening efficiency.

[0004] While the aforementioned patent achieves flour dispersion through the setting of a dispersing rod during flour screening, it can only move the flour and improve screening efficiency. However, it cannot compress and disperse lumps of flour, making it impossible to crush slightly lumpy flour. This necessitates secondary processing of the lumpy flour after screening, reducing screening efficiency. Furthermore, the accumulation of lumpy flour affects subsequent screening efficiency. Therefore, it is necessary to design a flour processing screening device that can compress and disperse lumpy flour. Utility Model Content

[0005] To address the above technical problems, this utility model provides a screening device for flour processing.

[0006] To solve the above-mentioned technical problems, the present invention provides a screening device for flour processing, including a screening component, the screening component including a frame, a screening cylinder connected to the top of the frame via a shock-absorbing spring, and a vibration motor connected to the bottom center of the screening cylinder;

[0007] It also includes a pressing cylinder, which is located inside the sieving cylinder above it and is used to extrude and disperse flour particles. The pressing cylinder is connected to a lifting assembly on the outside, which is used to adjust the pressing cylinder up and down.

[0008] Furthermore, a guide plate and a filter screen are fixedly connected to the inner wall of the screening cylinder, with the guide plate positioned below the filter screen.

[0009] Furthermore, the outer wall of the pressing cylinder is integrally formed with a positioning ring, the bottom of the pressing cylinder has an arc-shaped flared structure, the top of the pressing cylinder has a conical flared structure, and the pressing cylinder is positioned above the filter screen.

[0010] Furthermore, the lifting assembly includes a column, and a bearing ring is fixedly connected to the top of the column.

A lifting plate is fixedly connected to the lifting end of the lifting cylinder, and the lifting plate is fixedly connected to the outer wall of the pressure cylinder.

[0011] Furthermore, the bottom of the column is fixedly connected to the bottom support lug of the frame, the cross-section of the bearing ring is L-shaped, and the corner of the bearing ring is integrally formed with reinforcing ribs.

[0012] Furthermore, a support ring is integrally formed on the inner wall of the bearing ring, and a corrugated protective cover is connected above the support ring and the positioning ring.

[0013] This utility model has the following advantages compared with the prior art:

[0014] 1. This utility model suspends the pressing cylinder above the filter screen, so that when the filter screen is vibrated by the vibrating motor, it can cause the clumped flour particles to collide with each other, thereby dispersing the clumped flour and preventing the accumulation of clumped flour residue. This ensures the subsequent filtration effect of the filter screen and can also compress and disperse the clumped flour after filtration. Attached Figure Description

[0020] The present invention will be further described below with reference to the accompanying drawings.

[0021] like Figures 1 to 4 The diagram shows a screening device for flour processing, including a screening assembly 1. The screening assembly 1 includes a frame 11, with a screening cylinder 13 connected to the top of the frame 11 via a shock-absorbing spring 12. A vibration motor 16 is connected to the center of the bottom of the screening cylinder 13. A pressing cylinder 2 is located above and inside the screening cylinder 13, and is used for extruding and dispersing flour particles. A lifting assembly 3 is connected to the outside of the pressing cylinder 2 for adjusting its height. A guide plate 14 and a filter screen 15 are fixedly connected to the inner wall of the screening cylinder 13, with the guide plate 14 positioned below the filter screen 15. 14. The filter screen 15 is installed at an angle with the discharge end being the lowest point. The center of the screen is slightly higher than the surrounding area, which facilitates the movement of flour clumps to the surrounding area for crushing. Through the setting of the pressing cylinder 2, when the device is processing flour sieving, the vibration of the filter screen 15 drives the clumps of flour to move to the surrounding area. At the same time, the clumps of flour can be squeezed and dispersed by contact with the bottom of the pressing cylinder 2, so that the flour can be fully sieved and dispersed. At the same time, the squeezing and dispersing of the flour prevents clumps of flour from remaining on the top of the filter screen 15, ensuring the long-term filtration performance of the filter screen 15.

[0022] In order to achieve secondary extrusion and dispersion of the clumps of flour filtered on the filter screen 15, the pressing cylinder 2 is designed to extrude and disperse the clumps of flour filtered above the filter screen 15. At the same time, the arc-shaped flared structure design can better transfer the circumferentially displaced clumps of flour to the bottom of the pressing cylinder 2. The outer wall of the pressing cylinder 2 is integrally formed with a positioning ring 21. The bottom of the pressing cylinder 2 has an arc-shaped flared structure, and the top of the pressing cylinder 2 has a conical flared structure. The pressing cylinder 2 is located above the filter screen 15.

[0023] To achieve the lifting and adjustment of the pressing cylinder 2 to adapt to different screening requirements, the height of the pressing cylinder 2 can be adjusted up and down by lifting the lifting cylinder 34, thereby adjusting the distance between the pressing cylinder 2 and the filter screen 15. By adjusting the distance between the pressing cylinder 2 and the filter screen 15, flour particles of different specifications can be ground. The lifting component 3 includes a column 31, and a bearing ring 32 is fixedly connected to the top of the column 31. A support plate 33 is integrally formed on the top of the bearing ring 32, and a lifting cylinder 34 is fixedly connected to the upper surface of the support plate 33. A lifting plate 35 is fixedly connected to the lifting end of the lifting cylinder 34, and the lifting plate 35 is fixedly connected to the outer wall of the pressing cylinder 2.

[0024] To improve the stability and firmness of the support ring 32, the strength of the support ring 32 is increased by setting reinforcing ribs, thereby improving the load-bearing effect of the support ring 32. Then, the support ring 32 is suspended and supported by the connection of the column 31. The bottom of the column 31 is fixedly connected to the bottom lug of the frame 11. The cross-section of the support ring 32 is L-shaped, and the corner of the support ring 32 is integrally formed with reinforcing ribs.

[0025] To reduce the dispersion of flour during the screening process, the corrugated protective cover 4 provides good coverage, thereby reducing the dispersion of flour. At the same time, its flexible corrugated structure ensures the resonance of the screening cylinder 13. The resonance of the screening cylinder 13 drives the filter screen 15 to vibrate, thus achieving flour screening. The inner wall of the bearing ring 32 is integrally provided with a support ring, and the corrugated protective cover 4 is connected above the support ring and the positioning ring 21.

[0026] The working process of this embodiment is as follows:

[0027] First, an appropriate amount of flour is added above the filter screen 15 through the pressing cylinder 2. Simultaneously, the vibration motor 16 is energized and starts the sieving cylinder 13 to vibrate. The vibration of the sieving cylinder 13 then drives the guide plate 14 and the filter screen 15 to vibrate. The vibration of the filter screen 15 causes qualified flour to fall above the guide plate 14. As the guide plate 14 vibrates, the flour moves closer to the edge of the sieving cylinder 13 and is discharged through the discharge port on the outside of the sieving cylinder 13. While the filter screen 15 vibrates, the clumps of flour filtered above move to the surroundings. Through the setting of the pressing cylinder 2, the clumps of flour are squeezed against the bottom of the pressing cylinder 2, thus crushing the clumps of flour. Further, the vibration of the filter screen 15 completes the sieving of the flour, thereby improving the efficiency of the device. At the same time, the pressing cylinder 2 can be adjusted up and down by the lifting component 3, which can adjust the distance between the pressing cylinder 2 and the filter screen 15. Furthermore, the sieving of flour of different sieving specifications can be achieved by adjusting the distance between the pressing cylinder 2 and the filter screen 15.
