Description

TECHNICAL FIELD

[0001] The present application relates to flour by-product production and processing equipment technical field, especially to a flour by-product bin auxiliary discharging mechanism and working method. BACKGROUND

[0002] The by-product of flour is mainly the non-flour component produced in the process of wheat processing, mainly referring to bran. The bran has multiple uses, especially widely used in food, feed and industrial fields. The bran refers to the outer epidermis of wheat, which is separated out in the milling process and is temporarily stored in the bran bin.

[0003] In the normal production process, the bran bin is fed at the top and discharged at the bottom, and the materials are simultaneously fed and discharged. The bran material will not accumulate in the bin for a long time, so it will not form an arching situation, and the discharge is smooth. If the production line equipment fails, it needs to be overhauled and stopped, or it needs to be maintained and stopped. The bran material itself is astringent and has large friction resistance. It accumulates and is pressed in the bin, and it is easy to arch, so when the production line resumes production, it will cause difficult discharge. The current solution is to manually knock the side wall of the bin for vibration, which is time-consuming and laborious, and the discharge is not smooth.

[0004] In order to overcome the above problems, a flour by-product bin auxiliary discharging mechanism is needed. SUMMARY

[0005] The purpose of the present application is to provide a flour by-product bin auxiliary discharging mechanism, which uses a stirring shaft to stir the arching material, so that the flour by-product material is smoothly discharged.

[0006] To solve the above technical problems, the present application adopts the following technical scheme: The present application provides a flour by-product bin auxiliary discharging mechanism, which is arranged on a flour by-product bin. A conical cylinder part is coaxially arranged at the bottom of the flour by-product bin. A discharger is connected to the bottom end of the conical cylinder part. The discharger is connected to a pneumatic conveying pipeline. The mechanism comprises a driving unit and a horizontal stirring shaft. Bearing seats are symmetrically arranged at one end of the conical cylinder part close to the discharger. The horizontal stirring shaft is arranged on the bearing seats at both ends. The driving unit is installed on one side of the bearing seat and the output shaft is coaxially connected to the horizontal stirring shaft. The horizontal stirring shaft is provided with a material stirring rod for stirring the flour by-product material in the conical cylinder part.

[0007] Further, the driving unit specifically adopts a first speed reducer motor or a crank handle. The material stirring rod is a plurality of rods arranged radially along the main shaft of the horizontal stirring shaft and directly welded to the main shaft at the root.

[0008] Further, the upper stirring assembly is capable of stirring the flour by-product material above the conical cylinder part, preventing the adhesion of the material to the inner wall of the flour by-product bin and the arching of the main bin.

[0009] Further, the upper stirring assembly comprises a second speed reducer, a gearbox, a support plate frame and a vertical stirring shaft. The gearbox is supported by the support plate frame at the center of the bottom of the main bin section of the flour by-product bin. The second speed reducer is installed on the outer wall of the bottom of the main bin section of the flour by-product bin. The output shaft of the second speed reducer outputs power to the side wall input shaft end of the gearbox through a transmission shaft. The output shaft of the gearbox is connected vertically upward to the vertical stirring shaft. A plurality of horizontal stirring rods are arranged on the vertical stirring shaft.

[0010] Further, the cross section of the main bin section of the flour by-product bin is rectangular in profile, and the conical cylinder part is a prismatic conical cylinder. The total length of the two symmetrical stirring rods at the bottom end of the vertical stirring shaft is less than the width of the rectangular profile of the cross section of the main bin section. The end of the stirring rod at the bottom end is fixed with a flexible stirring soft shaft.

[0011] In order to reduce space waste, the cross section of the main bin section of the flour by-product bin is generally not circular in profile, so the stirring rod rotating will inevitably have a dead angle. How to overcome the material stirring in the dead angle area is an important challenge faced by the inventor.

[0012] Further, the upper stirring assembly further comprises a rotating cover. The rotating cover is coaxially fixedly connected to the root of the vertical stirring shaft. The skirt of the disc cover of the rotating cover is buckled on the top edge of the cylindrical cover of the gearbox.

[0013] Further, the upper stirring assembly further comprises a self-rotation driving member. A central shaft sleeve is radially arranged at the root of the vertical stirring shaft. A supporting sleeve is fixedly connected to the skirt of the disc cover. The stirring rod at the bottom end is coaxially rotatably penetrated in the central shaft sleeve and the supporting sleeve. The self-rotation driving member is capable of self-rotation driving the stirring rod at the bottom end.

[0014] Further, the self-rotation driving member comprises a bevel gear and a bevel gear rack. The bevel gear is coaxially installed on the stirring rod at the bottom end and connected by a flat key. The bevel gear rack is a circular arc gear rack and is capable of meshing with the bevel gear. The installation position of the bevel gear rack is towards the top corner of the rectangular profile of the cross section of the main bin section.

[0015] Further, the stirring rod at the bottom end specifically adopts a rotating sleeve with a hole. The flexible stirring soft shaft specifically adopts a rubber rod. The root of the rubber rod is inserted into the port of the rotating sleeve and locked by a pipe thread lock nut.

[0016] The application further discloses a working method of the auxiliary discharging mechanism of the flour by-product bin.

[0017] Compared with the prior art, the application has the following beneficial technical effects: The auxiliary discharging mechanism of the flour by-product bin directly stirs the material at the part most prone to arching at the bottom of the conical cylinder by arranging the horizontal stirring shaft, breaks the arching and makes the material fall into the discharger below under the action of gravity. The auxiliary discharging mechanism of the flour by-product bin stirs the arching material by the stirring shaft, so that the flour by-product material is smoothly discharged.

[0018] In addition, the upper stirring assembly is additionally arranged to stir the flour by-product material above the conical cylinder, so that the material adhesion to the inner side wall of the flour by-product bin and the arching of the main bin are prevented; the gearbox is arranged to reverse the power of the output shaft of the second speed reducer motor, drives the vertical stirring shaft to rotate, the material at the bottom and the middle of the vertical main bin of the flour by-product bin can be stirred and loosened by the material stirring rod of the vertical stirring shaft, so that the material adhesion and the arching of the main bin are broken. The elastic material stirring flexible shaft is fixedly connected to the end of the material stirring rod, the elastic material stirring flexible shaft can be elastically bent to scrape the place that cannot be reached by the end of the material stirring rod, so that the overall cleaning is realized. The elastic material stirring flexible shaft is additionally arranged at the bottom of the material stirring rod, so that the material at the bottom of the main bin of the flour by-product bin can be loosened in all directions, and the material above can fall down under the action of gravity. The rotating cover is additionally arranged at the root of the vertical stirring shaft, so that the sealing assembly at the root of the vertical stirring shaft is protected, and the dust and sundries in the material are prevented from entering the gearbox. The self-rotation driving member is additionally arranged to drive the material stirring rod at the bottom to self-rotate, so that the bending position of the elastic material stirring flexible shaft is changed, the elastic material stirring flexible shaft is prevented from being difficult to recover due to long-term directional bending at one place, and the material at the corner is prevented from being stirred. The bevel gear is driven by the bevel gear rack with an arc segment, the elastic material stirring flexible shaft is driven to self-rotate by a small angle to complete the switching of the bending position every revolution of the vertical stirring shaft. The installation position of the bevel gear rack is reasonably arranged, so that the elastic material stirring flexible shaft is self-rotated when the length direction of the elastic material stirring flexible shaft has the largest activity allowance, on the one hand, the self-rotation resistance is reduced, and on the other hand, the material stirring effect is improved. The rotating sleeve is used as the material stirring rod at the bottom, the connection strength is improved by cooperating with the inserted rubber rod, and the anti-disconnection effect is achieved. The pipe thread segment is connected by the pipe thread lock nut, the narrow gap is compressed, the inner wall of the pipe thread segment is pressed onto the outer wall of the rubber rod to achieve effective locking.

[0023] The core of the application is to provide an auxiliary discharging mechanism of a flour by-product bin, which adopts a stirring shaft to stir arching material, so that the flour by-product material is smoothly output.

[0024] The technical solutions in the embodiments of the application will be clearly and completely described below in combination with the drawings in the embodiments of the application. Obviously, the described embodiments are only a part of the embodiments of the application, rather than all the embodiments of the application. Based on the embodiments in the application, all other embodiments obtained by those skilled in the art without creative work fall within the protection scope of the application.

[0025] ​In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as limiting the present invention.

[0026] With reference to the accompanying drawings, Figure 1 This is a schematic diagram of the main structure of the auxiliary discharge mechanism of the flour by-product silo of the present invention; Figure 2 This is a schematic diagram of the main cross-sectional structure of the auxiliary discharge mechanism of the flour by-product silo of the present invention; Figure 3 for Figure 2 Schematic diagram of the cross-sectional structure of the middle AA part; Figure 4 This is a schematic diagram of a top-down cross-sectional structure of the rotating cover portion of the present invention; Figure 5 for Figure 2 Schematic diagram of the partial cross-sectional structure of part I in the middle.

[0027] Example 1 In a specific implementation of this embodiment, as Figure 1 and Figure 2 As shown, the auxiliary discharge mechanism for the flour by-product silo of the present invention is mounted on a flour by-product silo 1. A conical cylindrical portion 101 is coaxially disposed at the bottom of the flour by-product silo 1. The bottom end of conical cylindrical portion 101 is connected to a discharger 2, which is in turn connected to a pneumatic conveying pipe. Above the discharger 2, the cross-sectional area of ​​the bottom of conical cylindrical portion 101 decreases, making this location most susceptible to arching, hindering smooth discharge.

[0028] In a specific implementation of this embodiment, as Figure 1 and Figure 2 As shown, the auxiliary discharge mechanism for the flour by-product silo of the present invention includes a drive unit and a horizontal stirring shaft 4. Bearing seats 102 are symmetrically arranged at one end of the conical cylinder 101 near the discharger 2. Both ends of the horizontal stirring shaft 4 are rotatably mounted on the bearing seats 102. The drive unit is mounted on one side of the bearing seats 102, and the output shaft is coaxially connected to the horizontal stirring shaft 4. The horizontal stirring shaft 4 is provided with a stirring rod on the conical cylinder 101 to stir the flour by-product material.

[0029] By disposing a horizontal stirring shaft 4 at the bottom of the conical cylinder 101, the material is stirred directly at the part most prone to arching, breaking the arch and allowing the material to fall into the discharger 2 below under the action of gravity. The auxiliary discharge mechanism of the flour by-product silo of the present invention uses a stirring shaft 5 to move the arched material, allowing the flour by-product material to be discharged smoothly.

[0030] Specifically, if Figure 1 and Figure 2As shown, the driving unit specifically adopts a first reduction motor 3 or a crank handle, and the first reduction motor 3 is connected to the main shaft of the horizontal stirring shaft 4 through a shaft coupling. The stirring rods are radially arranged along the main shaft of the horizontal stirring shaft 4 and are directly welded to the main shaft.

[0031] The horizontal stirring shaft 4 is driven by the first reduction motor 3 or the crank handle, so that the horizontal stirring shaft 4 can be powered to stir the materials. That is, the first reduction motor 3 can be controlled by an electrical program to be intermittently started, or the crank handle can be manually driven by an operator.

[0032] Embodiment 2 When the production line is stopped for a long time, the bran materials will often be bonded and arch-shaped in the vertical main warehouse part of the flour by-product warehouse 1 under the long-time static pressure. The horizontal stirring shaft 4 in the above embodiment 1 cannot stir and loosen the bonding and arching in this part.

[0033] On the basis of the above embodiment 1, targeted improvement is made to form the present embodiment, as shown in Figure 1 and Figure 2 As shown, the auxiliary discharging mechanism of the flour by-product warehouse further comprises an upper stirring assembly, which can stir the flour by-product materials above the conical cylinder part 101, so as to prevent the bonding of the materials on the inner wall of the flour by-product warehouse 1 and the arching of the main warehouse.

[0034] Specifically, as shown in Figure 1 and Figure 2 The upper stirring assembly comprises a second reduction motor 5, a gearbox 6, a support plate frame 7 and a vertical stirring shaft 15. The gearbox 6 is supported at the center position of the bottom of the main warehouse section of the flour by-product warehouse 1 through the support plate frame 7, the support plate frame 7 comprises a center flat plate and three legs, the roots of the three legs are fixed on the inner wall of the conical cylinder part 101 through an attached plate, and the bottom surface of the gearbox 6 is installed on the center flat plate. The second reduction motor 5 is installed on the outer wall of the bottom of the main warehouse section of the flour by-product warehouse 1, and the output shaft of the second reduction motor 5 outputs power to the side wall input shaft end of the gearbox 6 through a transmission shaft 501. The gearbox 6 mainly changes the transmission direction of the power. The output shaft of the gearbox 6 is connected to the vertical stirring shaft 15 vertically upward and can drive the vertical stirring shaft 15 to rotate. A plurality of horizontal stirring rods are arranged on the vertical stirring shaft 15.

[0035] Obviously, the second reduction motor 5 can also be replaced by a hydraulic motor or a manual crank handle, and such a simple replacement falls within the protection scope of the present application.

[0036] By adding the upper stirring component, the flour by-product material above the conical cylinder 101 is stirred, thereby preventing the material from sticking to the inner wall of the flour by-product silo 1 and the main silo from arching; by setting the gearbox 6 to divert the power of the output shaft of the second reduction motor 5, the vertical stirring shaft 15 is driven to rotate, and the stirring rod of the vertical stirring shaft 15 can stir and loosen the flour by-product material at the bottom and middle of the vertical main silo of the flour by-product silo 1, thereby destroying the material adhesion and the arching of the main silo.

[0037] This embodiment is applicable to the cylindrical main bin of the flour by-product silo 1 , and the circular motion of the prying rod can more thoroughly pry and loosen the material on the inner side wall of the main bin of the flour by-product silo 1 .

[0038] Example 3 However, the traditional flour by-product silo 1 is constructed using cement masonry walls. The main section of the flour by-product silo 1 often has a rectangular cross-section, while the conical section 101 is a pyramid. Some modified flour by-product silos 1, though constructed from steel, also retain a rectangular profile. In this case, the circular motion of the moving rod prevents the moving of flour by-products from reaching the long sides and inner corners. If these remain attached to the inner walls of the silo for extended periods, they can become moldy and deteriorate, affecting the quality of the flour by-products before they leave the factory.

[0039] Based on the above embodiment 2, targeted improvements are made to form this embodiment, such as Figure 2 and Figure 3 As shown, the total length of the two symmetrically arranged material-dividing rods at the bottom of the vertical stirring shaft 15 is less than the width of the rectangular outline of the cross section of the main chamber section, with a difference of between 100 mm and 200 mm. An elastic material-dividing soft shaft is fixed to the end of the material-dividing rod at the bottom.

[0040] By fixing the elastic material-dividing flexible shaft to the end of the material-dividing roller, the elastic material-dividing flexible shaft can bend elastically and scrape the places that the end of the material-dividing roller cannot reach, thereby achieving all-round cleaning. By adding the elastic material-dividing flexible shaft to the bottom end of the material-dividing roller, the bottom of the main bin of the flour by-product silo 1 can be loosened in all directions, and the upper materials can fall under their own weight.

[0041] Specifically, if Figures 2 to 4 As shown, the upper stirring assembly also includes a rotating housing 8, which is coaxially fixedly connected to the base of the vertical stirring shaft 15. The rotating housing 8 is a cylindrical shell with an opening facing downward, and includes a top plate and a disc housing 801. The center of the top plate of the rotating housing 8 is welded to the base of the vertical stirring shaft 15. The bottom skirt of the disc housing 801 is buckled onto the cylindrical top edge of the gearbox 6.

[0042] Specifically, a dustproof ring is arranged on the inner edge of the bottom skirt of the disc cover 801, which can prevent the flour by-product material from entering the rotating cover 8 from bottom to top.

[0043] By additionally arranging the rotating cover 8 at the root of the vertical agitation shaft 15, the sealing assembly at the root of the rotating cover 8 can be protected, and dust and sundries in the material can be prevented from entering the gearbox 6.

[0044] In a specific embodiment of the present embodiment, as shown in Figures 2 to 4 The upper agitation assembly further comprises a rotation driving member. A central shaft sleeve 151 is arranged radially on the central axis of the rotating cover 8, and a supporting sleeve 802 is fixedly connected to the skirt of the rotating cover 8. The bottom end of the poking stick is coaxially and rotatably penetrated into the central shaft sleeve 151 and the supporting sleeve 802. The rotation driving member can drive the bottom end of the poking stick to rotate.

[0045] Specifically, as shown in Figure 4 The rotation driving member comprises a bevel gear 10 and a bevel gear rack 11. The bevel gear 10 is coaxially installed on the bottom end of the poking stick and is connected by a flat key. The bevel gear rack 11 is a circular arc gear rack and can be engaged with the bevel gear 10. That is, the bevel gear rack 11 is not a complete gear but a circular arc gear rack. The bevel gear rack 11 is installed on the top plate of the gearbox 6 by a countersunk screw 12. The installation position of the bevel gear rack 11 is directed to the top corner of the rectangular profile of the main bin section of the flour by-product bin 1.

[0046] Obviously, the rotation driving member can also be realized by a friction wheel and a friction pad. The friction wheel is coaxially installed on the bottom end of the poking stick, and the friction pad is fixedly connected to the top plate of the gearbox 6. The friction pad can contact and drive the friction wheel to rotate by a certain angle, thereby realizing the rotation of the bottom end of the poking stick. Similar simple replacement methods also fall within the protection scope of the present application.

[0047] By additionally arranging the rotation driving member to drive the bottom end of the poking stick to rotate, the bending position of the elastic poking flexible shaft can be changed, the difficulty of recovery caused by long-term directional bending of the elastic poking flexible shaft at one place can be avoided, and the situation that the material at the corner cannot be poked can be avoided. By driving the bevel gear 10 by the bevel gear rack 11 which is a circular arc gear rack, the elastic poking flexible shaft can be rotated by a small angle for each revolution of the vertical agitation shaft 15, and the bending position can be switched. By reasonably arranging the installation position of the bevel gear rack 11, the elastic poking flexible shaft can be rotated when the length direction activity allowance is the largest, which can reduce the rotation resistance and increase the material agitation effect.

[0048] Specifically, as shown in Figure 4As shown, the small end of bevel gear 10 is installed in the snap spring slot of the outer wall of the poking stick by snap spring 13 for axial positioning. The center shaft sleeve 151 is also axially positioned by another snap spring 13 towards the end face of bevel gear 10.

[0049] The working process of the embodiment is as follows: the second speed reducer 5 outputs power to the gearbox 6 through the transmission shaft 501, the gearbox 6 drives the vertical stirring shaft 15 to rotate, the poking stick of the vertical stirring shaft 15 can stir and loosen the flour by-product material in the vertical main warehouse bottom and the middle part of the flour by-product warehouse 1, and can destroy the material bonding and the main warehouse arch. During the rotation of the bottom end of the poking stick, the elastic poking soft shaft fixedly connected to the end head can contact the inner side wall of the main warehouse bottom and be elastically bent to scratch the place that the end head of the poking stick cannot reach, thereby realizing omnidirectional cleaning. When the bottom end of the poking stick rotates to the top corner position range of the rectangular cross section of the main warehouse section, the bevel gear 10 and the bevel gear rack 11 are engaged, the bevel gear 10 is driven to rotate, and the bottom end of the poking stick is rotated to realize the switching of the bending position of the elastic poking soft shaft.

[0050] Embodiment 4 On the basis of the above-mentioned embodiment 3, the installation mode of the elastic poking soft shaft is improved to form the embodiment. As shown in Figures 2 to 5 As shown, the bottom end of the poking stick specifically adopts a rotating sleeve 9 with a hole, and the elastic poking soft shaft specifically adopts a rubber stick 14, and the root of the rubber stick 14 is inserted into the port of the rotating sleeve 9 and locked by using a pipe thread lock nut 16.

[0051] Specifically, as shown in Figure 5 As shown, the pipe thread segment 901 of the end of the rotating sleeve 9 is provided with three narrow slits in the axial direction, and when the pipe thread lock nut 16 is connected to the pipe thread segment 901, the inner wall of the pipe thread segment 901 can be pressed against the outer wall of the rubber stick 14 to achieve locking.

[0052] Specifically, as shown in Figure 3 As shown, the outer wall of the pipe thread lock nut 16 is provided with a radial threaded hole, and a jack 17 is installed in the threaded hole, and the inner end of the jack 17 can be pressed against the pipe thread segment 901 to achieve the anti-loose effect.

[0053] Specifically, the rubber stick 14 is compounded with a steel wire rope core 141 at the center position, and the two are vulcanized together.

[0054] By using the rotating sleeve 9 as the bottom end of the poking stick, the rubber rod 14 can be inserted to improve the connection strength and prevent the rubber rod from falling off. The pipe thread segment 901 is connected to the pipe thread lock nut 16, the narrow gap is compressed, the inner wall of the pipe thread segment 901 is pressed against the outer wall of the rubber rod 14 to achieve effective locking. By adding the top wire 17, the pipe thread lock nut 16 is prevented from loosening. By vulcanizing the steel wire core 141 into the rubber rod 14, the toughness of the rubber rod 14 is increased and the service life is improved.

[0056] By intermittently rotating the horizontal stirring shaft 4 and the vertical stirring shaft 15, the arching flour by-product materials can be stirred to smoothly flow to the discharger 2 for output.

[0057] The embodiments in the specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments.
