Description

Technical Field

[0001] The utility model belongs to the technical field of flour processing, and in particular relates to an integrated flour drying and screening device. Background Art

[0002] Flour is ground from wheat. Terms like "high-gluten wheat flour" refer to what we commonly call flour. Wheat flour is categorized by properties and uses into specialty flour (such as bread flour, dumpling flour, and biscuit flour), all-purpose flour (such as standard flour and enriched flour), and fortified flour (such as calcium-fortified and iron-enriched flour). It is also categorized by fineness into special first-grade flour, special second-grade flour, standard flour, and regular flour. It is also categorized by gluten strength into high-gluten flour, medium-gluten flour, and low-gluten flour.

[0003] In the process of realizing the present utility model, the inventors found that there are at least the following problems in this technology: when processing flour, it involves drying and screening, so as to ensure the quality of the flour, wherein drying is to remove moisture and avoid agglomeration, and screening is to remove impurities therein; the current drying and screening devices for flour processing have two processes, namely, drying and screening, which are basically separate, resulting in a transfer process of flour between the two processes, which reduces the efficiency of drying and screening.

[0004] To this end, we proposed an integrated flour drying and screening device to solve the above problems. Utility Model Content

[0005] The main purpose of the utility model is to provide an integrated flour drying and screening device, in which drying and screening are both performed on a screening plate, thereby greatly improving the efficiency of drying and screening, and effectively solving the problems in the background technology.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0007] A flour drying and screening integrated device comprises a processing tank, a drying mechanism and a screening mechanism located on the processing tank. A feeding pipe is fixedly connected to the center of the top wall of the processing tank. The feeding pipe extends deep into the inner cavity of the processing tank to feed flour onto the drying mechanism. A discharge pipe is fixedly connected to the center of the bottom wall of the processing tank.

[0008] The drying mechanism includes four electric heating tubes respectively installed on the four side walls of the inner cavity of the processing tank, that is, there are four electric heating tubes in total, and the four electric heating tubes are distributed on the four sides of the inner cavity of the processing tank. The technical principle of the electric heating tubes is the existing technology, which requires power supply from external power facilities. The screening mechanism includes a cylinder fixedly connected to one side wall of the processing tank, a telescopic rod fixedly connected to the cylinder, and a screening plate fixedly connected to the telescopic rod. The inner cavity of the screening plate is formed on its top wall for accommodating flour to be dried and screened, and a plurality of through holes communicating with its inner cavity are formed on the bottom wall of the screening plate.

[0009] Extension plates are symmetrically welded on both sides of the bottom wall of the screening plate, and bottom grooves are formed on the bottom walls of the two extension plates. A servo motor is horizontally installed on one of the extension plates, and a screw and a slide rod are respectively provided in the two bottom grooves. The output shaft of the servo motor is coaxially connected to the screw, and both sides of the slide rod are welded to the other extension plate. A bottom sealing plate is provided under the two extension plates, wherein one side of the bottom sealing plate is threadedly sleeved on the screw, and the other side thereof is slidably sleeved on the slide rod, and a number of discharge holes are formed on the bottom sealing plate.

[0010] As a preferred embodiment, support legs are fixedly connected to the four corners of the bottom wall of the treatment tank, and the four support legs are distributed in a rectangular array; so that the support legs can support all structures on the treatment tank to make it stable.

[0011] As a preferred embodiment, the opening of the inner cavity of the treatment tank is located on one side wall thereof, and a side door is connected to the side wall where the opening of the inner cavity of the treatment tank is located through multiple hinges; a U-shaped handle is also installed on the side door, and the side door can be pulled by holding the handle to open the opening of the inner cavity of the treatment tank, thereby facilitating the cleaning of the screening plate.

[0012] As a preferred embodiment, the screw and the slide rod are both arranged horizontally, and both sides of the screw are rotatably connected to the extension plate; so that the screw can operate stably under the drive of the servo motor.

[0013] As a preferred embodiment, a side support is fixedly connected to the side of the inner cavity of the processing tank facing away from the telescopic rod, and a pulley is fixedly connected to the side of the screening plate facing away from the telescopic rod, wherein the pulley rolls on the side support; when the screening plate moves, it can drive the pulley to roll on the side support to ensure the balance of the screening plate.

[0014] As a preferred embodiment, the diameter of the discharge hole is the same as the diameter of the through hole, and the number of the discharge holes is also the same as the number of the through holes; when the through hole and the discharge hole coincide with each other, the flour in the inner cavity of the sieve plate can be discharged.

[0015] In summary, the technical effects and advantages of the utility model are:

[0016] The flour drying and screening integrated device drives the screening plate to move back and forth in the inner cavity of the processing tank through the operation of the cylinder, so that the flour material in the screening plate vibrates, so that the flour material can be dried more quickly. After the drying is completed, the servo motor only needs to drive the screw to move to move the bottom sealing plate, thereby opening the through hole, allowing the flour material to be screened on the screening plate to screen out the solid impurities therein. Since the drying and screening are both carried out on the screening plate, the drying and screening efficiency is greatly improved.

[0017] In this integrated flour drying and screening device, when flour is added from the adding pipe and falls into the inner cavity of the screen plate, the flour will also vibrate as the screen plate vibrates, and is dried in an environment heated by two electric heating tubes. After that, the servo motor is driven to drive the screw to operate, so that the bottom sealing plate is appropriately translated along with the sliding rod until all the discharge holes coincide with all the through holes one by one. At this time, the flour will fall from the discharge holes and finally be discharged from the discharge pipe, thereby completing the drying and screening work on the screen plate at the same time, thereby improving the efficiency of drying and screening.

[0026] The drying mechanism includes four electric heating tubes 5 respectively installed on the four side walls of the inner cavity of the processing tank 1, that is, there are four electric heating tubes 5 in total, and the four electric heating tubes 5 are distributed on the four sides of the inner cavity of the processing tank 1. The technical principle of the electric heating tube 5 is the existing technology, which requires power supply from external power facilities. The screening mechanism includes a cylinder 7 fixedly connected to one side wall of the processing tank 1, a telescopic rod 8 fixedly connected to the cylinder 7, and a screening plate 9 fixedly connected to the telescopic rod 8. The inner cavity of the screening plate 9 is formed on its top wall for accommodating flour to be dried and screened. A plurality of through holes 10 communicating with its inner cavity are formed on the bottom wall of the screening plate 9. The opening of the inner cavity of the processing tank 1 is located on one side wall. A side door 6 is connected to the side wall where the opening of the inner cavity of the processing tank 1 is located by multiple hinges. A U-shaped handle is also installed on the side door 6. By holding the handle, the side door 6 can be pulled to open the opening of the inner cavity of the processing tank 1, thereby facilitating the cleaning of the screening plate 9.

[0027] Extension plates 11 are symmetrically welded on both sides of the bottom wall of the screening plate 9, and bottom grooves 13 are formed on the bottom walls of the two extension plates 11. A servo motor 12 is horizontally installed on one of the extension plates 11. A screw 14 and a slide bar 15 are respectively provided in the two bottom grooves 13. The output shaft of the servo motor 12 is coaxially connected to the screw 14. Both sides of the slide bar 15 are welded to the other extension plate 11. The screw 14 and the slide bar 15 are both horizontally arranged. Both sides of the screw 14 are rotatably connected to the extension plate 11, so that the screw 14 can operate stably under the drive of the servo motor 12. A bottom sealing plate 16 is provided below the two extension plates 11. One side of the bottom sealing plate 16 is threadedly sleeved on the screw 14, and the other side thereof is slidably sleeved on the slide rod 15. A plurality of discharge holes 17 are formed on the bottom sealing plate 16. The diameter of the discharge holes 17 is the same as that of the through holes 10, and the number of the discharge holes 17 is the same as that of the through holes 10. When the through holes 10 and the discharge holes 17 coincide with each other, the flour in the inner cavity of the sieve plate 9 can be discharged.

[0028] In addition, a side support 19 is fixedly connected to the side of the inner cavity of the processing tank 1 facing away from the telescopic rod 8, and a pulley 18 is fixedly connected to the side of the screening plate 9 facing away from the telescopic rod 8, wherein the pulley 18 rolls on the side support 19, so that when the screening plate 9 moves, it can drive the pulley 18 to roll on the side support 19 to ensure the balance of the screening plate 9.

[0029] The integrated flour drying and screening device: before use, the two electric heating tubes 5 are powered on and run, and the environment in the inner cavity of the treatment tank 1 is heated until the temperature reaches a suitable value; when in use, the driving cylinder 7 drives the telescopic rod 8 to extend and retract, so that the screening plate 9 can reciprocate in the inner cavity of the treatment tank 1, driving the pulley 18 to roll on the side support 19. At this time, the structure of the screening plate 9 is very stable; when flour is added from the adding tube 2 and falls into the inner cavity of the screening plate 9, as the screening plate 9 vibrates, the flour will also vibrate and be dried in the environment heated by the two electric heating tubes 5; (the through hole 10 and the discharge hole 17 at this time do not coincide, so the flour will stay on the screening plate 9 inner cavity, will not fall) after the drying work is completed, the servo motor 12 is driven to drive the screw 14 to operate, so that the bottom sealing plate 16 is appropriately translated along with the slide rod 15 until all the discharge holes 17 are coincident with all the through holes 10 one by one. At this time, the flour will fall from the discharge holes 17 and eventually be discharged from the discharge pipe 3, while the solid impurities contained in the flour will remain on the sieve plate 9 (the size of the solid impurities is larger than the diameter of the through hole 10, so they cannot fall). Subsequently, the opening of the inner cavity of the processing tank 1 is opened through the side door 6 to clean up the solid impurities on the sieve plate 9, thereby completing the drying and screening work on the sieve plate 9 at the same time, thereby improving the efficiency of drying and screening.
