Description

Technical Field

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

[0002] Flour is the powdery material made from wheat after the husk has been removed. It can be made into a variety of pasta foods, such as steamed buns, noodles, pancakes, and cold noodles. Flour is classified into high, medium, and low gluten strengths based on its protein content. To prevent impurities from being carried into the flour during processing, it needs to be filtered.

[0003] The flour mixture is introduced into the filter structure, where it is sieved by shaking and agitation to purify the flour by separating different particles. However, the powder is easily released into the air and scattered everywhere, resulting in a reduction in the weight of the filtered flour and a significant increase in filtration costs.

[0004] Now, a novel flour screening device for flour processing is proposed to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a flour screening device for flour processing, so as to solve the problem of lack of protective structure mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a flour screening device for flour processing, comprising an outer frame and a limiting plate. The limiting plate is fixed around the center of the inner part of the outer frame, and a motor is fixed on both sides of the top of the limiting plate. A gear is fixed on the top of the output end of the motor. An annular groove is provided around the inner side of the limiting plate. A sieve frame is movably connected inside the limiting plate, and a cover plate is fixed on the top of the sieve frame. A cylinder is fixed at the bottom of the outer side of the sieve frame. A filter screen is fixed inside the top of the sieve frame. Slider blocks are fixed on both sides below the outer surface of the sieve frame. Tooth blocks are fixed around the surface of the sieve frame. A cover plate is fixed on the top of the outer frame.

[0007] As a further technical solution of this utility model, the side of the gear meshes with the tooth block, and the slider is embedded in the annular groove.

[0008] As a further technical solution of this utility model, a second motor is fixed on both sides of the bottom end of the cylinder, a stirring rod is movably connected to both sides below the surface of the cylinder, and a discharge valve is fixed on the lower right corner of the outer frame.

[0009] As a further technical solution of this utility model, the bottom of the output end of the second motor is fixedly connected to the stirring rod, and the stirring rod rotates horizontally at the bottom end inside the outer frame.

[0010] As a further technical solution of this utility model, a guide tube is fixed at the center of the inside of the second cover plate, and a feed valve is installed above the guide tube. A hopper is installed at the top of the feed valve. A positioning plate is fixed below the guide tube. Through grooves are arranged longitudinally on both sides of the positioning plate. A flexible hose is fixed between the center of the bottom of the positioning plate and the pressure plate. A support rod is movably inserted into the through groove, and a spring is fixed between the top of the support rod and the positioning plate. A pressure plate is fixed between the bottom of the support rod. A feed port is movably connected at the center of the inside of the second cover plate.

[0011] As a further technical solution of this utility model, the pressure plate is attached to the top of the feed inlet, and the spring is wrapped around the outside of the support rod.

[0012] Compared with the prior art, the beneficial effects of this utility model are: the flour screening device for flour processing not only avoids flour splashing and realizes synchronous pushing of flour output, but also realizes precise delivery of flour materials;

[0013] (1) A screen frame is connected inside the limiting plate. Flour in the hopper is injected into the screen frame through the guide tube through the cover plate. The motors on both sides are started to rotate the gears at the same speed and direction, so that they push the screen frame with a ring of toothed blocks fixed on the surface. At this time, the slider at the bottom of the screen frame also slides along the annular groove. Flour is separated from the filter screen by centrifugal force and impurities are retained. After the end, the cover plate is opened and the cover plate is opened to clean the screen frame to avoid impurities or powder splashing everywhere.

[0014] (2) By connecting stirring rods on both sides below the surface of the cylinder, while the screen frame rotates horizontally at the top of the limiting plate, the stirring rods on both sides are also controlled and rotated by motor 2, forming a scraping mechanism at the bottom of the outer frame, gradually sweeping the flour deposited below the outer frame to the right side, and discharging the powder material after the discharge valve is opened, without having to open the entire device for cleaning, ensuring that the inner wall of the outer frame is clean enough.

[0015] (3) By having a feed inlet connected to the center inside the second cover plate, after the second cover plate is closed, the height of the pressure plate can be adjusted along the through grooves on both sides of the positioning plate under the pressure of the spring, so that the pressure plate is tightly attached to the feed inlet, which makes it convenient to introduce the flour in the hopper into the sieve frame for sieving after the feed valve is opened, and can provide pressing force to prevent the first cover plate from being lifted.

[0023] The side of gear 4 meshes with the tooth block 5, and slider 16 is embedded in an annular groove 15;

[0024] Specifically, such as Figure 1 and Figure 2 As shown, the flour in the hopper 9 is injected into the sieve frame 6 through the cover plate 7 via the conduit 18. The motors 3 on both sides are started to rotate the gear 4 at the same speed and direction, so that they push the sieve frame 6, which has a ring of toothed blocks 5 fixed on its surface. At this time, the slider 16 at the bottom of the sieve frame 6 also slides along the annular groove 15, using centrifugal force to separate the flour through the filter screen 11 and retain impurities. After the process is completed, the cover plate 8 and the cover plate 7 are opened to clean the sieve frame 6.

[0025] Motor 17 is fixed on both sides of the bottom of the cylinder 12. Stirring rods 13 are movably connected on both sides below the surface of the cylinder 12. Discharge valve 14 is fixed on the lower right corner of the outer frame 1. The bottom of the output end of motor 17 is fixedly connected to stirring rod 13. Stirring rod 13 rotates horizontally at the bottom of the outer frame 1.

[0026] Specifically, such as Figure 1 and Figure 3 As shown, while the sieve frame 6 rotates horizontally at the top of the limiting plate 2, the stirring rods 13 on both sides are also controlled and rotated by the motor 17, forming a scraping mechanism at the bottom of the outer frame 1, which gradually sweeps the flour deposited below the outer frame 1 to the right side. After the discharge valve 14 is opened, the powder material is discharged without opening the entire device for cleaning.

[0027] A guide tube 18 is fixed at the center of the inside of the cover plate 28, and a feed valve 10 is installed above the guide tube 18. A hopper 9 is installed at the top of the feed valve 10. A positioning plate 21 is fixed below the guide tube 18. Through grooves 25 are arranged longitudinally on both sides of the positioning plate 21. A flexible hose 24 is fixed between the center of the bottom of the positioning plate 21 and the pressure plate 22. A support rod 19 is movably inserted into the through groove 25.

After the sieving process is completed, the second cover plate 8 and the first cover plate 7 are removed to remove debris.

[0029] Working principle: In use, flour from hopper 9 is fed into sieve frame 6 through guide tube 18, passing through cover plate 7. Motors 3 on both sides are started to rotate gear 4 at the same speed and direction, pushing the sieve frame 6, which has a ring of toothed blocks 5 fixed to its surface. At the same time, slider 16 at the bottom of sieve frame 6 slides along annular groove 15, using centrifugal force to separate the flour through filter screen 11 while retaining impurities. After use, cover plate 8 and cover plate 7 are opened to clean sieve frame 6. While sieve frame 6 rotates horizontally at the top of limiting plate 2, stirring rods on both sides... 13 is also controlled and rotated by motor 17, forming a scraping mechanism at the bottom of the outer frame 1, which gradually sweeps the flour deposited below the outer frame 1 to the right side. After the discharge valve 14 is opened, the powder material is discharged without opening the entire device for cleaning. After the cover plate 8 is closed, under the pressing action of the spring 20, the height of the pressure plate 22 can be adjusted along the through grooves 25 on both sides of the positioning plate 21, so that the pressure plate 22 is tightly attached to the feed inlet 23, which makes it convenient to introduce the flour in the hopper 9 into the sieve frame 6 for sieving after the feed valve 10 is opened.
