Description

Technical Field

[0001] The invention relates to the technical field of base material screening, in particular to screening equipment for producing liquor base material. Background Art

[0002] Liquor base material production screening equipment plays a vital role in liquor production. Its main function is to screen and process liquor base materials to ensure that the quality of the base materials meets production requirements; Base material is an important component of liquor, which contains a variety of materials, such as corn, sorghum, wheat, peas, etc. Sorghum has a high starch content, is easy to ferment, and contains an appropriate amount of tannins and anthocyanins. Peas also contain protein and starch, which are beneficial to improve the quality and taste of liquor. The best base material will bring better taste and flavor. For sorghum or peas in the selection process, the base material will be mixed with impurities such as gravel, dead leaves, branches, etc., and improper handling will directly affect the quality of the finished wine; Secondly, when selecting, there will be dust mixed in the germination grooves on the surface or inside the gaps. At the same time, the winery will grade the products due to material problems. If the peas and sorghum are of poor quality, such as shriveled, moldy, etc., a series of problems may occur, affecting the wine body. Due to their own defects, shriveled peas and sorghum have less fermentation substances and starch, which will lead to a decrease in the wine yield. At the same time, shriveled raw materials or less full raw materials will have less flavor substances. When making high-end wines, the flavor of the wine will be relatively monotonous, and the wine body will become relatively thin. The shriveled material has a harder texture, and requires longer soaking time and longer crushing in subsequent processing. Summary of the invention

[0013] Compared with the prior art, the present invention has the following beneficial effects: The present invention provides a screening device for liquor base material production. Through the arrangement of an auxiliary mechanism, a material dividing block and a screening mechanism, when peas or sorghum pass through an inclined plate, they fall in batches and then fall onto the surface of a trigger plate. Stones are polygonal, not circular, and their shapes are different from the force-bearing surface. Peas and sorghum are close to spherical shapes. When leaves, gravel and branches contact the trigger plate, they have a large energy loss and fall into the lower part of the inner part of the material dividing block. Then, they are guided and collected by the wind force of the folded tube. Better peas fall onto the surface of the screening plate for collection. Moldy peas and sorghum are lighter in weight and may be damp due to the disease, which may damage the internal structure and reduce their elasticity so that they enter the lower part of the material dividing block and are sent away. Furthermore, when peas or sorghum pass through the surface of the screening plate, some longer branches may get stuck in the gap between the screening plate and the trigger plate. At this time, the auxiliary mechanism is driven by the driving mechanism to pull the screening plate to perform arc motion in a small range. The branches will move toward the waste due to the movement of the screening plate. At the same time, when the auxiliary mechanism pulls to perform arc motion, the relatively round and full peas will roll to the place with low slope through the guidance of the matching rectangular strip, while the unfull ones will be screened out due to excessive kinetic energy loss when passing through the matching rectangular strip due to their shape and weight disadvantages. If the longer branches are stuck at both ends when falling, they will swing and slide toward the waste due to the arc motion, and bend or break them. Through the setting of the driving mechanism and the connecting mechanism, the raw materials that have been preliminarily screened are processed synchronously. When the raw materials enter the upper part of the processing block, the brush bar and the soft brush are used to flip the movement of the rod body. The soft brush moves in a small range to clean the germination groove of the peas or the dust in the gap, and then the dust is sent away by the airflow. Furthermore, when the wine of some wineries needs to be graded, the peas, sorghum, etc. need to be screened again. When the raw materials enter the interior of the connecting mechanism and are cleaned by a soft brush, they fall onto the surface of the first curved screen block and the second curved screen block. When the peas fall onto the highest platform on the top of the second curved screen block, the weight and shape of the full peas and the less full peas will cause the full peas to move out of the second curved screen block through centrifugal force during the falling process, and finally fall to the bottom of the first curved screen block. The rest will fall through the second curved screen block and finally be separated. After rotation and diversion, they are used to make wines of different qualities.

[0022] The first driving motor 22 drives the first matching tooth 23 to work, and at the same time, the first matching tooth 23 drives the first large tooth 32 to rotate forward and reverse within a set range, and at the same time, the flipping rod body 24 works synchronously. The reciprocating motion trajectory of the flipping rod body 24 is less than or equal to the trajectory of the first large tooth 32.

[0024] The coupling mechanism 5 includes a processing block 51 arranged at the top of the polygonal box 1, and the interior of the processing block 51 is provided with a plurality of dust outlet holes 52 in a circular array, and the interior of the processing block 51 is provided with matching brush strips 53 staggered with the plurality of dust outlet holes 52, and a diversion pipe 54 is provided at the bottom of the surface of the processing block 51, and an auxiliary plate 55 is provided at the edge of the end of the diversion pipe 54, and a first curved screen block 56 is provided at the end of the auxiliary plate 55 away from the opening of the diversion pipe 54, and a second curved screen block 57 is provided on the surface of the first curved screen block 56 at the same rotation angle as that of the first curved screen block 56.

[0025] An inclined plate 19 is disposed at the top of the material distribution block 11 , and baffles are disposed at the edges of both sides of the top of the inclined plate 19 .

[0026] The baffle is provided to prevent the materials on both sides from sliding and slipping out when the device is in use.

[0027] A feeding plate is obliquely arranged at the bottom end of the inclined plate 19 .

[0028] The feeding plate under the inclined plate 19 is hollow, and the part of the inclined plate 19 close to the curved baffle 47 is low. The material is first fed by the inclined plate 19, and then transported horizontally in batches through the hollow feeding plate. The part of the feeding plate close to the curved baffle 47 is a small opening, and the interior is a conical or trapezoidal chamber, which transports the material to the trigger plate body 46. Before use, the trigger plate body 46 needs to adjust its inclination angle, and then it is fixed on both sides close to the curved baffle 47 through fixed holes opened on the material distribution block 11 or by other means to prevent it from unnecessary tilting.

[0029] First, sorghum or peas enter the material dividing block 11 of the device for processing. When the material enters the inclined plate 19 and touches the surface of the adjustable trigger plate 46, hard stones, bad fruits and deflated fruits will have less elasticity when touching the inclined surface, and will fall into the separation chamber 14 of the polygonal box 1, intercepting long branches and other long debris. Because when branches touch the inclined surface, if the ends touch, they may run into the screening plate 41. At this time, due to the setting of the baffle, when the other end falls onto the platform, it is processed in time and falls into the waste area for collection and processing. The full particles have a higher elasticity and will continue to move, fall to the surface of the screening plate 41, and then enter the collection chamber 15.

[0030] A sliding door is hingedly connected to the side of the polygonal box body 1 close to the separation chamber 14 , and a chamfered hole is opened on the side of the polygonal box body 1 close to the processing block 51 .

[0031] The interior of the material distribution block 11 is divided into two independent chambers by a first separation plate 12 arranged vertically, wherein one independent chamber is connected to the interior of the separation chamber 14, and the other independent chamber is connected to the interior of the collection chamber 15, and the collection chamber 15 is divided into two upper and lower parts by a second separation plate 17, and the processing block 51 is installed in the upper half of the collection chamber 15, and a part of the gas from the folded tube 6 enters the interior of the material distribution block 11, and the oblique wind hole on the trigger plate 46, away from the side of the arc surface baffle 47, blows part of the wind obliquely upward, and the wind force inside the material distribution block 11 is After being blown out from the oblique wind holes, the wind is blocked by the oblique angle surface on the back of the screening plate 41 to prevent the wind from blowing to the upper surface of the screening plate 41. The other part of the folded tube 6 enters into the collecting chamber 15 and is also blown upward by the wind. The wind inside the collecting chamber 15 is greater than the wind inside the dividing block 11. The inward part of the dust outlet hole 52 is larger than the outward part. There is an inclined baffle at the edge of the curved baffle 47 on the surface of the screening plate 41. When longer branches are blocked and moved toward the slope surface of the trigger plate 46, they are then taken away by the wind for centralized processing.

[0032] A rectangular hole is provided on the surface of the polygonal box 1 near the bottom of the second curved screen block 57 , and a folded tube 6 is fixedly connected to the output end of the blower 16 , and the end of the folded tube 6 is connected to the distribution block 11 and the inner middle of the collection chamber 15 . Specific implementation method; When in use, personnel feed the material to the top of the inclined plate 19, and then when the material enters the inside of the feed plate inclined at the bottom of the inclined plate 19, the thickness of the material will become lower, forming batch feeding, and then when the material enters the inside of the dividing block 11, the driving mechanism 2 starts to work, and the material will first contact the surface of the trigger plate 46, and then the stones, leaves and mold will be screened and fall under the trigger plate 46, and then the folding pipe 6 connected to the output end of the blower 16 will blow the debris under the screening plate 41 downward, and then collect it in the separation chamber 14. At the same time, the driving mechanism 2 starts to operate, and the first matching tooth 23 will drive the first large tooth 32 to start working, and the first large tooth 32 drives the first connecting rod 33 to reciprocate in a small range, pulling the screening plate 41 to start working, and the long branches stuck with the fallen dead leaves will be shaken downward, or broken, and then the peas are screened. At the inclined surface away from the plate body 41, the full ones will gradually fall down through the separation of the rectangular strip 42, while the shriveled ones will stay at a position close to the arc-surface baffle 47 and then be screened out. When the full peas or sorghum follow the path into the processing block 51, the first drive motor 22 above the processing block 51 drives the auxiliary mechanism 3 while turning the rod body 24 to make the soft brush 25 cooperate with the matching brush strip 53 inside the processing block 51. At the same time, the upward wind force led by the folding tube 6 will send out the dust in the upper half of the collection chamber 15 separated by the second separation plate 17, and then the raw materials will fall into the top of the second curved screen block 57 just below the center of the auxiliary disk 55 through the diversion pipe 54. At this time, the fuller raw materials will escape the running track of the second curved screen block 57 and roll on the surface of the first curved screen block 56. When the classification is completed, it is sent into the wine making different wine bodies.
