Description

Technical Field

[0001] The utility model belongs to the technical field of soy sauce production, and particularly relates to a raw material screening mechanism for soy sauce production. Background Art

[0002] The main raw materials for soy sauce production include protein raw materials, starch raw materials, salt and water, etc. Protein raw materials include soybeans or defatted soybeans, starch raw materials include wheat, bran, flour, broken rice and corn, etc. The screening of these raw materials is an important step in the soy sauce production process.

[0003] Screening removes impurities such as dust, sand, and metal fragments from raw materials, ensuring product quality and consumer health. Screening also helps ensure uniform mixing of raw materials, ensuring a smooth soy sauce brewing process. Certain raw materials may have a particle size unsuitable for specific production equipment, so screening can adjust the particle size to suit the production line.

[0004] At present, in order to improve screening efficiency and avoid material clogging of the screen, a stirring blade is set above the screen of the rotary vibrating screen used for soy sauce raw material production. The rotation of the stirring blade can promote the flow of material on the screen, increase the dynamic dispersion of the material, and help the powder material to pass through the screen holes smoothly. However, this rotary vibrating screen with stirring blades is often a single-layer screen. During the design, the agitator is designed to be a liftable structure, so that the lifting and lowering adjustment of the agitator will facilitate the replacement and cleaning of the screen. However, this screening mechanism with stirring blades is not suitable for a multi-layer screen structure because the stirring shaft connected to the stirring blade needs to pass through the center of the multi-layer screen for fixation, which is inconvenient for the replacement of the multi-layer screen. Utility Model Content

[0005] The present invention aims to solve the technical problem that in the prior art, only stirring blades can be provided on a single-layer mesh rotary vibrating screen.

[0006] To achieve the above objectives, the present invention provides the following technical solutions:

[0007] A raw material screening mechanism for soy sauce production includes a screening assembly and an agitator. The screening assembly is composed of a plurality of multi-layer screens arranged sequentially from top to bottom and stacked. Each multi-layer screen includes a circular screen frame with a central hole and four sector-shaped screens detachably mounted on the circular screen frame. The sector-shaped screens on the multi-layer screens decrease in size from top to bottom.

[0008] The agitator includes a motor, a stirring shaft fixedly connected to the motor and rotatably connected to the bearing in the center hole, and several groups of stirring blades arranged on the stirring shaft at equal distances and respectively located in each layer of the multi-layer screen. The stirring blades are located above the fan-shaped screen.

[0009] Preferably, the multi-layer screen is provided with at least 2 layers. Multi-layer screening can simultaneously separate raw materials of different particle sizes.

[0010] Preferably, the circular screen frame includes a circular outer frame, a feeding guide nozzle connected to the internal space of the circular outer frame, a center sleeve forming a center hole, four connecting plates connecting the circular outer frame and the center sleeve and arranged at equal distances around the circumferential direction of the center sleeve, and a fan-shaped support plate fixed in the fan-shaped through hole formed by two adjacent connecting plates and the circular outer frame.

[0011] Preferably, a frame edge is provided on the outside of the fan-shaped screen, and the frame edge is limited above the fan-shaped support plate. A clamping block is provided on the inner side of the frame edge close to the center sleeve, and the clamping block is engaged with the clamping position on the outside of the center sleeve. A connecting block integrally formed with the frame edge is fixed on the inner side of the outer edge of the frame edge and located at the bottom of the fan-shaped screen. An inner thread hole is opened on the connecting block, and a locking screw passing through the circular outer frame is threadedly connected to the inner thread hole to fix the fan-shaped screen in the circular screen frame.

[0012] The design of the frame edge and the positioning with the center sleeve facilitate the positioning and installation of one end of the sector screen to prevent the sector screen from shifting during vibration. The threaded connection between the inner thread hole on the connecting block and the locking screw on the circular outer frame provides a quick and firm way to fix the screen.

[0013] Preferably, fan-shaped blanking holes are provided in the fan-shaped support plate, and between two adjacent layers of multi-layer screens, the fan-shaped blanking holes on the upper multi-layer screen are designed to allow the four fan-shaped screens on the lower multi-layer screen to pass through.

[0014] The aperture of the upper fan-shaped blanking hole is larger than that of the lower fan-shaped screen, which facilitates the installation or disassembly of the fan-shaped screen layer by layer.

[0015] Preferably, the multi-layer screen is installed on the bottom trough on the rotary vibrating screen frame.

[0016] The design of the bottom trough helps to collect the materials after multi-layer screening.

[0017] Preferably, an inverted L-shaped bracket is fixedly connected to the rotary vibrating screen frame, and the motor is fixed on the inverted L-shaped bracket.

[0018] Compared with the prior art, the technical effects and advantages of the utility model are:

[0019] This raw material screening mechanism for soy sauce production solves the problem of traditional single-layer vibrating screens being limited to agitating blades. The screening mechanism is designed with multiple layers of screens, each with its own agitating blade. The size of each layer of screen decreases gradually, allowing for the separation of raw materials of varying particle sizes. The agitating blades also promote the flow of material across the screen, increasing dynamic dispersion. This solves the problem of traditional single-layer screens being unable to effectively separate raw materials of varying particle sizes.

[0020] The stirring blades are located above each layer of screen, which helps the material flow and dispersion. Because the stirring shaft is fixedly connected to the bearing through the center hole, and the bearing design ensures sufficient stability and strength, even if there is vibration during the screening process, it will not affect the normal operation of the agitator.

[0021] The fan-shaped screen is designed to be removable and can be quickly and securely fixed with the locking screws on the circular screen frame. This design greatly simplifies the replacement and cleaning process of the screen and solves the problem of inconvenient adjustment of the stirring blade in the multi-layer screen structure.

[0022] The circular screen frame and fan-shaped support plate design provide a strong and stable screen frame structure, which helps maintain the stability of the screen. The fan-shaped drop hole design helps the material fall smoothly from the upper screen to the lower screen, reducing material blockage and screen wear.

[0023] In summary, the design of this raw material screening mechanism for soy sauce production not only improves the screening efficiency and avoids material clogging of the screen, but also makes the replacement and cleaning of the multi-layer screen more convenient, which meets the demand for raw material screening in the soy sauce production process.

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] The following is combined with Figure 1-6 To further explain this application,

[0033] The present application discloses a raw material screening mechanism for soy sauce production, including a screening assembly 1 and an agitator 3. The screening assembly 1 is composed of a plurality of multi-layer screens 2 arranged sequentially from top to bottom and stacked. The multi-layer screens 2 are provided with at least two layers. The multi-layer screens 2 can simultaneously separate raw materials of different particle sizes, reducing the number of screenings and the corresponding time, thereby improving production efficiency. The different levels of screens can be used to screen according to different particle size requirements, making the particle size distribution of the raw materials more uniform, which is beneficial to the subsequent brewing process.

[0034] Each layer of the multi-layer sieve 2 comprises a circular sieve frame 21 with a central hole 2103 and four removable sector-shaped screens 22 mounted on the circular sieve frame. The sector-shaped screens 22 decrease in size from top to bottom. The agitator shaft 32 is fixedly connected to a bearing through the central hole 2103. The bearing design ensures sufficient stability and strength. The bearing, as the support structure for the agitator rod, effectively absorbs and disperses vibrations during the screening process, ensuring that even vibrations from the agitator shaft 32 during the screening process do not affect the normal operation of the agitator 3.

[0035] The circular screen frame 21 includes a circular outer frame 2101, a feeding guide nozzle 2102 connected to the internal space of the circular outer frame 2101, a center sleeve 2104 that surrounds a center hole 2103, four connecting plates 2105 that connect the circular outer frame 2101 and the center sleeve 2104 and are arranged at equal distances in the circumferential direction of the center sleeve 2104, and a fan-shaped support plate 2107 fixed in the fan-shaped through hole 2106 surrounded by two adjacent connecting plates 2105 and the circular outer frame 2101.

[0036] The combination of the circular outer frame 2101, the center sleeve 2104 and the connecting plate 2105 provides a strong and stable screen frame structure, which helps to maintain the stability of the screen during the screening process. The design of the discharge guide nozzle 2102 helps to smoothly drop the material, reducing the blockage and loss of the material during the screening process.

[0037] A frame edge 2201 is provided on the outside of the fan-shaped screen 22, and the frame edge 2201 is limited above the fan-shaped support plate 2107. A clamping block 2202 is provided on the inner side of the frame edge 2201 near the center sleeve 2104, and the clamping block 2202 is engaged with the clamping position 2109 on the outside of the center sleeve 2104. A connecting block 2203 integrally formed with the frame edge 2201 is fixed on the inner side of the outer edge of the frame edge 2201 and located at the bottom of the fan-shaped screen 22. An inner thread hole 2204 is provided on the connecting block 2203, and a locking screw 23 passing through the circular outer frame 2101 is threadedly connected to the inner thread hole 2204 to fix the fan-shaped screen 22 in the circular screen frame 21.

[0038] The design of the frame edge 2201 and the cooperation with the clamping position 2109 of the center sleeve 2104 facilitate the alignment installation of the clamping position 2109 at one end of the fan-shaped screen 22, preventing the fan-shaped screen 22 from shifting during vibration. The threaded connection between the internal thread hole 2204 on the connecting block 2203 and the locking screw 23 on the circular outer frame 2101 provides a quick and firm way to fix the screen.

[0039] The fan-shaped support plate 2107 is provided with fan-shaped blanking holes 2108 . Between two adjacent layers of multi-layer screens 2 , the fan-shaped blanking holes 2108 on the upper multi-layer screen 2 are designed to allow the four fan-shaped screens 22 on the lower multi-layer screen 2 to pass through.

[0040] The design of the fan-shaped drop holes 2108 helps the material to fall smoothly from the upper screen to the lower screen, reducing material blockage and screen wear. In addition, the aperture of the upper fan-shaped drop holes 2108 is larger than the fan-shaped screen 22 of the lower layer, which facilitates the layer-by-layer installation or disassembly of the fan-shaped screen 22.

[0041] The agitator 3 includes a motor 31, a stirring shaft 32 fixedly connected to the motor 31 and rotatably connected to the bearing in the center hole 2103, and several groups of stirring blades 33 arranged at equal distances on the stirring shaft 32 and respectively located in each layer of the multi-layer sieve 2. The stirring blades 33 are located above the fan-shaped screen 22.

[0042] The circular screen frame 21 is provided with holes for cooperating with the fan-shaped screen 22 for fixing. The fan-shaped screen 22 is detachably arranged on the circular screen frame. The circular screen frame 21 is fixed. The circular screen frame 21 can be connected to the agitator 3. Four fan-shaped screens 22 are installed on the circular screen frame to form a circular screen. It is possible to add stirring blades 33 to the multi-layer screen 2 so that raw materials of different particle sizes can be separated more effectively. The stirring blades 33 are arranged above each layer of screen to facilitate the flow of material on the screen, increase the dynamic dispersion of the material, make the screening process smoother, and prevent the mesh of the fan-shaped screen 22 from being blocked.

[0043] The size of the screen decreases from top to bottom. This design allows the screen of the lower layer to pass through the holes reserved on the upper circular screen frame 21, making it convenient for the installation and removal of the fan-shaped screen 22 on each layer of the multi-layer screen 2. The fan-shaped screen 22 is designed to be detachable, which is convenient for the operator to clean and replace, reducing downtime for maintenance and improving production efficiency.

[0044] The multi-layer screen 2 is mounted on a bottom trough 5 on a vibrating screen frame 4. An inverted L-shaped bracket 6 is fixedly attached to the vibrating screen frame 4, and a motor 31 is secured to the bracket. The design of the bottom trough 5 helps collect material after passing through the multi-layer screen 2, minimizing material loss. The inverted L-shaped bracket 6 also helps secure the motor 31, ensuring more efficient power transmission.

[0045] Traditional single-layer vibrating screens can only screen a single particle size, while multi-layer screening and two-part separation mechanisms can simultaneously separate raw materials of different particle sizes. This reduces the number of screenings and the corresponding time, significantly improving production efficiency. By screening different particle size requirements through different layers of screens, the raw material particle size distribution can be uniform, which is beneficial to the subsequent brewing process.

[0046] The stirring blades 33 above the multi-layer screen 2 facilitate the flow and dispersion of materials on the screen, increasing the dynamic dispersion of the materials and helping the powdered materials pass through the screen mesh smoothly, thereby reducing the problem of material clogging the screen. Compared with single-layer vibrating screens, the stirring blades 33 in the multi-layer screen 2 structure can be optimized for each layer of the screen, better adapting to the screening needs of materials of different particle sizes.

[0047] The multi-layer sieve 2 provides a finer screening effect, separating raw materials of different particle sizes, which is particularly important for particle size control of raw materials in soy sauce production. At the same time, the design of the stirring blade 33 ensures the effective flow of materials during the screening process, improving the screening efficiency.

[0048] The detachable fan-shaped screen 22 design allows operators to quickly clean and replace the screen, reducing downtime for maintenance and thus improving production efficiency. The combination of the circular screen frame 21, the center sleeve 2104, and the connecting plate 2105 provides a sturdy and stable screen frame structure, which helps maintain the stability of the screen during the screening process and reduces inaccurate screening or screen damage caused by screen vibration. The fan-shaped drop holes 2108 design helps materials fall smoothly from the upper screen to the lower screen, reducing material blockage and screen wear. At the same time, the design of the bottom trough 5 helps collect materials after multi-layer screening 2 points, reducing material loss.

[0049] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein.
