Description
Technical Field
[0001] The invention relates to the technical field of flour processing equipment, in particular to a sieving device for agglomerated flour after secondary processing. Background Art
[0002] Flour is generally stored in a warehouse in the form of stacks to increase the storage capacity of the warehouse. However, during the process of stacking flour, the flour on the lower layer is easily compressed and agglomerated due to poor ventilation, relatively high humidity, and the gravity of the flour on the upper layer. In addition, the flour is seriously affected by moisture, and as the storage time increases, it agglomerates and becomes moldy. Therefore, the flour on the lower layer of the stack needs to be processed again. The existing method of secondary processing of flour mainly uses a stirring rod to break up the agglomerated flour, and then passes it into a drying device to dry it. After drying, it needs to be sieved again, so that the completely secondary processed flour can be repackaged.
[0003] The invention with application number CN2018106643987 discloses an efficient drying and crushing device for agglomerate materials for flour processing, in which the structure is simple, the agglomerate materials are effectively mixed and stirred through a stirring shaft, and then the agglomerate materials are cut under the action of centrifugal force, and finally enter the drying cylinder to dry the agglomerate materials. However, since the agglomerated flour after crushing is uneven in size, and in order to ensure the quality of flour during the drying process, the flour drying time should not be too long, the agglomerated flour with a larger volume after crushing is not fully dried inside, and the flour cannot be processed into powder, so that the flour needs to be processed and screened multiple times in the subsequent process. In this repeated screening process, the processing steps will increase, and the process is relatively cumbersome for the secondary processing step of the agglomerated flour, and it is necessary to match a variety of equipment to process it, which will greatly increase the workload and reduce work efficiency.

[0015] Compared with the prior art, the advantages and positive effects of the present invention are:
[0016] 1. When it is necessary to perform secondary processing and screening on the agglomerated flour, the motor arranged on the upper fixed cylinder of the device is used to drive the internal central axis to rotate. After the central axis rotates, it will drive the screen at the bottom to rotate together. After the screen rotates, it will screen the flour falling from above. The screened and filtered flour falls onto the filter plate in the middle fixed cylinder below. During the falling process, the screen rotates and drives the stirring shaft to rotate. The sphere at the bottom of the stirring shaft will rotate on the filter plate. In this way, the fallen flour will be ground and stirred again to increase the crushing property of the flour. Then the filtered flour enters the outer rotating cylinder below. After the outer rotating cylinder rotates, it will rotate the flour entering inside again. The flour will roll and flip inside it continuously. During the rolling and flipping motion, the heat generated inside the outer rotating cylinder can dry the internal flour to avoid the phenomenon of flour moisture forming agglomerates, which improves the secondary processing of flour and improves the storage efficiency.
[0017] 2. A conveying wheel is set at the discharge port. When the conveying wheel rotates, it will improve the conveying effect by generating a rotating force, avoid the blockage caused by the accumulation of flour, and also improve the conveying effect.
[0018] 3. The rotation of the outer drum and the rotation of the central axis are realized by a linkage structure. When the central axis rotates, it not only drives the screen to rotate, but also drives the outer drum to rotate. This upper and lower double-layer structure and the structure of rotating inside and outside together are used to improve the quality of flour processing and effectively avoid flour agglomeration that affects subsequent storage and use.
[0019] 4. After the flour is processed for the first time by rotating the screen, the remaining granular flour will hit the inner gear teeth of the side wall in time. With the rolling of gear 1, the crushing effect is improved. Then, with the action of the stirring shaft on the filter plate below and the outer drum, the flour crushing property is improved again, which greatly reduces the processing procedures and the use of supporting equipment, improves work efficiency, and improves the quality of flour processing.

[0037] A straight channel type discharge port 17 is arranged on one side of the bottom of the base 1, and a conveying wheel 40 is arranged on the top of the discharge port 17. By arranging the circular structure of the conveying wheel 40, after the conveying wheel 40 rotates, the sifted flour will be driven down along the conveying trough 41 by the kinetic force generated by the rotation, and fall into the collecting box pre-placed below. The rotation of the conveying wheel 40 is used to realize the conveying, avoiding blockage during the conveying. Moreover, this conveying method can effectively prevent the flour from piling up during the conveying to cause conveying difficulties, thereby improving the conveying effect.
[0038] Detailed usage and function of this embodiment:
[0039] The flour that needs to be sieved for secondary processing of the agglomerated flour is put into the feed channel 6 and enters the screen 13. Under the control of the external connection, the driving motor 8 is operated, the motor 8 drives the shaft 9 to rotate, the shaft 9 drives the bevel gear 10 to rotate, the bevel gear 10 drives the meshing bevel gear 2 11 on one side to rotate, the bevel gear 2 11 will drive the central shaft 12 connected at the bottom to rotate, and the central shaft 12 will drive the screen 13 connected at the bottom to rotate. During the rotation of the screen 13, the flour on it will hit it continuously with the rotation. When the central shaft 12 is rotating, the connecting arm 26 will rotate with it, and the gear 27 connected to the end of the connecting arm 26 will rotate along the inner gear teeth 32. During the rotation, the side teeth of the gear 27 will mesh with the teeth between the inner gear teeth 32. When meshing, the flour that hits the upper surface will be crushed. The crushed flour and the flour on the screen 13 will be screened together with the rotation. The screened flour enters the filter plate 14 arranged at the bottom of the middle fixed cylinder 3 below. When the flour falls onto the filter plate 14, the central shaft 12 rotates, driving the stirring shaft 30 to rotate. The ball 37 at the bottom of the stirring shaft 30 rolls and rotates on the filter plate 14, rolling the flour again. The filtered flour falls into the outer drum 2. At the same time, the turbine 18 drives the vortex rod 19 on the side to rotate, and the vortex rod 19 drives the upper pulley 20 at the end to rotate. The upper pulley 20 drives the lower pulley 21 to rotate through the belt 22. After the lower pulley 21 rotates, it drives the gear 23 to rotate. After the gear 23 rotates, it drives the lower pulley 21 to rotate. The top wheel teeth 24 meshing with each other make the outer drum 2 rotate. While rotating, the heating tube 16 and the heating plate 25 are turned on. After the heating tube 16 and the heating plate 25 generate heat, the temperature inside the outer drum 2 will increase, and the flour inside will turn over and roll with the outer drum 2. The flour dried during the turning and rolling will fall into the base 1 along with the several filter holes 15, and then the driver is driven, and the driver drives the conveying wheel 40 to rotate. After the conveying wheel 40 rotates, the flour on the upper left side will rotate down along with the conveying trough 41, so that the conveying effect can be improved.
[0040] When the flour falls into the base 1, the cold temperature generated by the condensing sheet 28 provided on the inner wall of the base 1 cools the flour entering, which is conducive to its collection and processing. A collection box is provided below the discharge port 17 to facilitate the collection of flour. The collection box can be used for collection in a box or bag, or can be collected and processed according to needs.
[0041] When the shaft 29 rotates with the screen 13, the movement generated by the rotation will cause the gravity plate 34 set on the shaft 29 to move. Since there is a certain gap between the middle hole of the gravity plate 34 and the wall of the shaft 29, the gravity plate 34 will move up and down along the trajectory during the rotation. At the same time, with the connection of the spring 35 above, the gravity plate 34 will continuously hit the screen 13 below during the up and down movement. After the screen 13 is hammered, the flour adhered to it will be vibrated and shaken down. Some of the flour will also hammer the flour below when the gravity plate 34 hammers down, increasing the crushing property of the flour.
[0042] Through the above specific implementations, those skilled in the art can easily implement the present invention. However, it should be understood that the present invention is not limited to the above specific implementations. On the basis of the disclosed implementations, those skilled in the art can arbitrarily combine different technical features to achieve different technical solutions.
