Description

Technical Field

[0001] The utility model relates to a screening device, in particular to a koji raw material screening device. Background Art

[0002] The reason why we add koji to wine is that there are a large number of microorganisms growing on the koji, which can accelerate the conversion of starch, protein, etc. in grains into sugar and amino acids. Sugar is decomposed into ethanol, i.e. alcohol, by the action of yeast enzymes. At the same time, the koji itself contains starch and protein, etc., which are also raw materials for winemaking; the degree of crushing of the raw materials has a great relationship with the quality of the koji: if it is too fine, it will be sticky, the gaps in the koji will be small, the air permeability will be poor, the moisture and heat will not be easily lost, the microorganisms will grow slowly, and it is easy to cause water nesting, impermeability or ring aging; if it is too coarse, it will be less sticky, the gaps in the koji will be large, the moisture and heat will be easily lost, and it is easy to cause the koji to dry out prematurely and crack, the surface will not hang clothes, and the microorganisms will grow poorly. Therefore, the particle grading of the koji raw materials should be strictly controlled.

[0003] Existing koji raw material screening devices are mostly used to screen out excessively fine powders. However, the fine powders of grain crops are very sticky and can easily clog the screen, causing the fine powders to be unable to be screened out and reducing the screening efficiency.

[0018] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments. It should be noted that the embodiments and features in the embodiments of the present invention can be combined with each other without conflict.

[0019] like Figures 1 to 4 In the embodiment of the koji raw material screening device of the utility model shown, the koji raw material screening device includes an inclined screen 1, track grooves 2 are provided on both sides of the screen 1, driving blocks 3 are slidably connected in the track grooves 2, and a rotating shaft 4 is rotatably connected to the driving block 3. A sliding groove 5 for the rotating shaft 4 to slide is provided on the track groove 2, and a roller brush 6 is fixedly connected to the rotating shaft 4. The roller brush 6 is provided with hook-shaped bristles 7, and the roller brush 6 is in contact with the bottom surface of the screen 1. A fine material tray 8 is provided under the screen 1, a baffle 9 is provided at the top of the screen 1, and a coarse material opening 10 is provided at the bottom end of the screen 1.

[0020] Specifically, when the mesh of the screen 1 is clogged with the attached powder, the driving block 3 slides in the track groove 2, the driving block 3 drives the rotating shaft 4 to slide in the slide groove 5, the rotating shaft 4 drives the roller brush 6 to slide under the screen 1, and the roller brush 6 and the rotating shaft 4 rotate under the influence of the friction between the roller brush 6 and the screen 1. The hook-shaped bristles 7 of the roller brush 6 hook the mesh of the screen 1 when rolling, so that the attached powder falls or pushes out of the mesh to the top of the screen 1, and finally flows out from the coarse material port 10 or falls into the fine material tray 8 under the screen 1. The powder clogged in the mesh is hooked out by the rolling roller brush 6 and the hook-shaped bristles 7, thereby improving the screening efficiency.

[0021] In one embodiment of the present application, preferably, a screw rod 11 is provided in the track groove 2, and the two ends of the screw rod 11 are rotatably connected to the two ends of the track groove 2. A screw hole adapted to the screw rod 11 is provided on the driving block 3, and when the screw rod 11 rotates, it is used to drive the driving block 3 to slide back and forth in the track groove 2.

[0022] In one embodiment of the present application, preferably, a leak-proof plate 12 is provided under the screen 1, and the track groove 2, the baffle 9 and the leak-proof plate 12 enclose a groove 13 adapted to the roller brush, and a comb tooth 14 is provided on the baffle 6 in the groove 13. After the roller brush 6 cleans the powder in the mesh, it runs into the groove 13, and the roller brush 6 is rotated to make the comb teeth 14 comb the hook-shaped bristles 7 to clean the powder attached to the hook-shaped bristles. The powder is cleaned and falls onto the leak-proof plate 12 and is swept into the bristles or falls into the fine material tray 8 due to gravity.

[0023] In one embodiment of the present application, preferably, a motor 15 is fixedly connected to the track groove 2, and a driving shaft of the motor 15 is fixedly connected to the screw rod 11 for driving the screw rod 11 to rotate, so as to drive the driving block 3 to slide.

[0024] In one embodiment of the present application, preferably, a rotating motor 16 is fixedly connected to the driving block 3, and a driving shaft of the rotating motor 16 is fixedly connected to the rotating shaft 4, so as to rotate the roller brush 6 when cleaning the roller brush 6.

[0025] In one embodiment of the present application, preferably, a bracket 17 is provided under the screen 1, a spring 18 is fixedly connected between the bracket 17 and the screen 1, and a vibration motor 19 is fixedly connected to the bottom of the leakage-proof plate 12 to vibrate the screen 1 and improve the screening efficiency.

[0026] In summary, the koji raw material screening device in the above embodiment of the utility model, specifically, when the mesh of the screen 1 is blocked by the attached powder, the motor 15 is started, the motor 15 rotates to drive the screw 11 to rotate, driving the driving block 3 to slide in the track groove 2, the driving block 3 drives the rotating shaft 4 to slide in the slide groove 5, the rotating shaft 4 drives the roller brush 6 to slide under the screen 1, and the friction between the roller brush 6 and the screen 1 is affected or the rotating motor 16 is started to rotate the roller brush 6 and the rotating shaft 4, and the hook of the roller brush 6 When rolling, the hook-shaped bristles 7 hook the mesh of the screen 1, causing the attached powder to fall or push out of the mesh to the top of the screen 1, and finally flow out from the coarse material port 10 or fall into the fine material tray 8 under the screen 1. After cleaning, the roller brush 6 moves into the groove 13, and the rotating motor 16 is started to rotate the roller brush 6. The comb teeth 14 clean the hook-shaped bristles 7 on the roller brush 6, and the cleaned powder falls into the fine material tray 8. The rolling roller brush 6 cooperates with the hook-shaped bristles 7 to hook out the powder blocked in the mesh, thereby improving the screening efficiency.
