Abstract
Description
Technical Field
[0001] The utility model relates to a flour storage and conveying device, in particular to a flour storage and conveying device. Background Art
[0002] With the improvement of people's living standards and the increasing development of large-scale food production, flour mills have developed and produced special-purpose flour, namely special flour, according to the requirements of flour-based foods. Blending flour refers to producing several basic flours with different components and properties after wheat blending, and mixing them in appropriate proportions to make special flour that meets quality requirements. Additives can also be added during the mixing process. The said blending equipment includes a flour bin, a feeding auger, a blending scale, and a mixer.
[0003] With the increasing production capacity of the production line, the volume requirement for the flour bin is also getting larger and larger. After powder materials are stored in various bins, arching and bridging are likely to occur. If relying only on the slope of the conical hopper at the lower part of the bin, the powder needs to overcome a great resistance to flow out freely, so it is easy to cause the powder to be blocked in the bin. Usually, some mechanical equipment for the outflow of auxiliary materials is installed at the lower hopper at the bottom of the flour bin. Among them, the bottom discharge device of the bin is a commonly used mechanical equipment for assisting the powder to discharge from the bin. Its principle is to use the high-frequency vibration generated by the vibration motor to drive the middle components of the bottom discharge device of the bin, thereby breaking the arching of the powder in the flour bin and enabling the powder to flow out of the bottom of the bin orderly and smoothly.
[0004] In the prior art, a very important component in the bottom discharge device of the bin is the material leveling plate. The outer shape of the material leveling plate is conical. The powder in the flour bin enters the gap between the material leveling plate and the outer shell of the bottom discharge device under the guidance of the material leveling plate and finally discharges from the bottom end of the outer shell of the bottom discharge device. During this process, if the falling material does not directly contact the material leveling plate from directly above the material leveling plate, it will cause uneven stress on the material leveling plate. Long-term application will cause stress damage at the connection between the material leveling plate and the outer shell of the bottom discharge device, resulting in damage to the structure of the bottom discharge device of the bin and requiring disassembly and repair. Therefore, the structural strength between the material leveling plate and the outer shell of the bottom discharge device of the bin needs to be strengthened to maintain the structural stability of the material leveling plate and further improve the durability of the bottom discharge device of the bin. Summary of the Invention

[0020] A flour output pipe 13 is provided at the bottom end of the conical hopper 2. A flap butterfly valve 28 is provided on the flour output pipe 13. An inlet pipe 14 is provided below the flour output pipe 13. A conveying pipe 15 is provided below the inlet pipe 14. A driving shaft 16 is provided on the conveying pipe 15. An auger 17 is provided on the driving shaft 16 inside the conveying pipe 15. A driving motor 18 is connected in transmission to the driving shaft 16 outside the conveying pipe 15. Elastic connecting pipes 19 are respectively provided on the flour output pipe 13 and the inlet pipe 14, as well as on the conical hopper 2 and the storage tank 1. The elastic connecting pipe 19 is a tubular structure made of rubber material. Clamps 20 are respectively provided on the elastic connecting pipe 19 outside the flour output pipe 13, the elastic connecting pipe 19 outside the inlet pipe 14, the elastic connecting pipe 19 outside the conical hopper 2, and the elastic connecting pipe 19 outside the storage tank 1. Thus, it is convenient to seal the gap between the flour output pipe 13 and the inlet pipe 14, as well as the gap between the conical hopper 2 and the storage tank 1. Shellac varnish layers 21 are respectively provided on the inner wall of the storage tank 1, the inner wall of the conical hopper 2, and the inner wall of the flour output pipe 13; thus, the corrosion caused by the moisture released in the flour to the storage tank 1, the conical hopper 2, and the flour output pipe 13 is reduced.
[0021] The buffer assembly further includes first rubber disc springs 22 respectively provided on the guide rod 5 between the first nut 7 and the second flange 4, and on the guide rod 5 between the first flange 3 and the second nut 8; the first nut 7 is threadedly connected to the guide rod 5, and the second nut 8 is threadedly connected to the guide rod 5; installing the first rubber disc springs 22 reduces the hard contact between the first flange 3 and the second nut 8, as well as the hard contact between the first nut 7 and the second flange 4, and reduces the phenomenon of stress breakage between the first flange 3 and the second nut 8 or between the first nut 7 and the second flange 4. The number of the buffer assemblies is several, and several of the buffer assemblies are evenly distributed in a star shape outside the central axis of the second flange 4. The central axis of the second flange 4, the central axis of the first flange 3, the central axis of the storage tank 1, and the central axis of the conical hopper 2 are located on the same axis; installing several of the buffer assemblies improves the force uniformity of the conical hopper 2. A support 23 is provided outside the storage tank 1. A bearing ring 24 is provided on the support 23 below the first flange 3. A second rubber disc spring 25 is provided between the bearing ring 24 and the first flange 3; thus, the load of the second flange 4 is reduced, and further the initial compression degree of the spring 6 is reduced.
[0022] A first level gauge 26 is provided inside the storage tank 1. Installing the first level gauge 26 facilitates feedback of the lowest level of the storage tank 1; a second level gauge 27 is provided inside the storage tank 1 above the first level gauge 26; installing the second level gauge 27 facilitates feedback of the maximum level that the storage tank 1 can hold.
[0023] The usage method of this product is as follows, such as Figure 1 andFigure 2 As shown, open the plug butterfly valve 28 and start the vibration motor 9 and the drive motor 18. The flour stored in the storage tank 1 moves downward under the action of gravity. When the vibration motor 9 is in the working state, the first flange 3, the conical hopper 2, the flour output pipe 13, the material leveling plate 10, the mounting ring 11 and the material leveling disc 12 vibrate up and down under the limit of the guide rod 5 in the buffer assembly. The flour in the storage tank 1 enters the flour output pipe 13 through the gap between the material leveling disc 12 and the conical hopper 2 and the gaps between several material leveling plates 10 under the action of the material leveling disc 12. The flour output pipe 13 then conveys the flour to the feed pipe 14 and the conveying pipe 15 in sequence. Under the action of the auger 17, the flour entering the conveying pipe 15 is conveyed to the outlet end of the conveying pipe 15.
[0024] Through this embodiment, several material leveling plates 10 are used to support the mounting ring 11 and the material leveling disc 12. The mounting ring 11 is supported at multiple points by several material leveling plates 10, so that the force received by the material leveling disc 12 mounted on the mounting ring 11 can be evenly transmitted to the conical hopper 2; installing several material leveling plates 10 not only increases the structural strength between the material leveling disc 12 and the conical hopper 2, but also can re-guide the flour guided by the material leveling disc 12 through the gaps between several material leveling plates 10; and when the instantaneous pressure received by the material leveling disc 12 is too large, the conical hopper 2 transmits the stress to the second flange 4, which prompts the second rubber disc spring 25 to be compressed and thus plays a buffering role, thereby reducing the stress breakage between the material leveling disc 12 and the conical hopper 2 caused by the instantaneous pressure on the material leveling disc 12 being too large.
[0025] The above embodiments are only the preferred embodiments of the present invention, and do not limit the scope of implementation of the present invention.
