A grain dryer is a mechanical device used to remove moisture from grains. It evaporates the moisture in the grains by using hot air or heated airflow to achieve the purpose of drying.

[0003] Existing grain dryers, such as the hot air circulating drying box proposed in patent application number "CN202322884147.9", include structures such as a heating box, a top cover, a drying mechanism, and a storage plate. The return air pipe at the air collection hopper discharges air, and in conjunction with the drying fan, the air with residual heat is blown from the drying fan to the heating box, where it is heated again through the heating pipe, enabling the entire device to achieve heat recycling.

[0004] However, existing technology has its drawbacks. When using grains, the grains to be dried are placed on a shelf for drying, and cannot be turned or rolled. This results in poor drying of the grains in the middle of the grain layer, requiring a long time to dry completely. Furthermore, manual unloading is required after drying, which is quite troublesome. Therefore, a grain circulation dryer is proposed. Utility Model Content

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0025] A grain circulating dryer, such as Figures 1-5 As shown, the device includes a drying box 1 for drying grains. Multiple sets of material guiding assemblies are inserted and installed inside the drying box 1. Each material guiding assembly includes a material guiding frame 8, which is inserted and installed into the drying box 1. A filter plate 9 is snapped onto the material guiding frame 8. The multiple sets of material guiding assemblies are all inclined and arranged in an alternating manner. A feed inlet 3 is fixedly connected to the upper end of the drying box 1. An outlet plate 5 is inclinedly fixedly connected to the inside of the drying box 1 below the material guiding assemblies. An outlet 4 is opened on one side of the drying box 1 corresponding to the lower end of the outlet plate 5.

[0026] By inserting the feeding assembly into the drying chamber 1, multiple sets of feeding assemblies are staggered, with the lower end of the upper feeding assembly located above the middle and upper end of the lower feeding assembly. The grain is discharged into the drying chamber 1 through the feed inlet 3 and rolls along the multiple sets of staggered inclined feeding assemblies. The hot air in the drying chamber 1 is discharged upward from the bottom of the drying chamber 1. The temperature inside the drying chamber 1 is high, and the grain is heated while rolling, resulting in uniform heating. After multi-layer rolling drying, the grain is finally discharged through the discharge plate 5. The grain in this dryer can be rolled and heated during the drying process, resulting in high drying efficiency, uniform heating, and automatic discharge.

[0027] The grains roll along the filter plate 9 of the feeding assembly. Dust or dander in the grains will pass through the filter plate 9 and enter the feeding frame 8. The feeding assembly can be pulled out, and the filter plate 9 can be removed from the feeding frame 8, making it easy to clean the dust and dander collected in the feeding frame 8. The dryer removes dust or dander from the grains during the drying process, improving the cleanliness of the grains after drying, making them easier to store and process later. The dryer has a wide range of functions.

[0028] like Figures 1-3 As shown, a side box 2 is fixedly connected to one side of the bottom of the drying box 1. A heating pipe 6 is fixedly connected inside the drying box 1 at a position below the discharge plate 5. The lower end of the side wall of the side box 2 is connected to the side wall of the drying box 1 at a position below the discharge plate 5. A vent 7 is provided between the upper end of the side wall of the side box 2 and the side wall of the drying box 1 at a position above the discharge plate 5. A ventilation opening 12 is provided on the side wall of the drying box 1 at a position below the heating pipe 6.

[0029] When the heating tube 6 is powered on, it heats the space at the bottom of the drying chamber 1. The air vent 7 vents air into the bottom of the drying chamber 1. The body enters the area where the heating tube 6 is located and heats up. Then, it enters the side chamber 2 from the connecting area between the side chamber 2 and the bottom of the drying chamber 1. It then enters the area of ​​the drying chamber 1 above the discharge plate 5 through the air vent 7 to heat and dry the inside of the drying chamber 1. Side air intake heating is used to prevent grains from falling into the air vent 7.

[0030] The area where the heating tube 6 is located at the bottom of the drying chamber 1 has a high temperature, which heats the discharge plate 5. This ensures that the grain is still heated and dried as it is discharged along the discharge plate 5. When the discharge port 4 is blocked, the grain will accumulate on the discharge plate 5. The discharge plate 5 can heat the grain for a long time.

[0031] like Figures 1-3 As shown, the upper end of the drying chamber 1 is connected to a second pipe 18, the end of the second pipe 18 is connected to a filter assembly, the lower end of the filter assembly is rotatably installed with a flexible hose 17, the lower end of the flexible hose 17 is connected to a drying assembly 16, the lower end of the drying assembly 16 is connected to a wind box 14 via a first pipe 15, and a blower 13 for communicating with a vent 12 is fixed to the side wall of the drying chamber 1, the air inlet of the blower 13 is connected to the wind box 14.

[0032] The air box 14 is connected to the first pipe 15, the drying component 16, the hose 17, the filter component, and the second pipe 18. Therefore, these structures, together with the blower 13 (model RB-31D-A1) and the drying box 1, form a cycle. The blower 13 drives the hot air to flow. The hot air in the drying box 1 flows from bottom to top and is discharged from the drying box 1 through the second pipe 18. The hot air carries heat, moisture and dust. It first enters the filter component to remove the dust, then passes through the drying component 16 to remove the moisture, and then enters the air box 14 to be drawn by the blower 13. This allows the exhaust gas discharged from the drying box 1 to be treated and utilized, and to be dried in a cycle, reducing heat loss.

[0033] The drying component 16 is existing technology, in which a material that can be used to dry the air is placed inside the drying cylinder, and the air passes through this material and absorbs moisture.

[0034] like Figure 5 As shown, the filter assembly includes a fixing plate 19, which is fixed to the pipe 18. A cylinder 20 is threadedly installed at the lower end of the fixing plate 19, and a filter screen 23 is threadedly installed at the lower end of the fixing plate 19 inside the cylinder 20.

[0035] Hot air first passes through filter screen 23 to remove dust before entering hose 17. Both filter screen 23 and cylinder 20 are removable for easy replacement or cleaning.

[0036] like Figure 5 As shown, a connecting pipe 24 is fixedly connected to the lower end of the cylinder 20, and the hose 17 is connected to the connecting pipe 24. A connecting ring 25 is rotatably installed on the outside of the connecting pipe 24 and the hose 17.

[0037] The joint gaps between the connecting pipe 24, the hose 17 and the connecting ring 25 are sealed, and the three can rotate relative to each other, making it easy for the cylinder 20 to be twisted to detach from the fixing plate 19, thus facilitating the disassembly of the filter assembly.

[0038] like Figure 1 and Figure 4 As shown, a sealing plate 10 is fixedly connected to one side of the guide frame 8. The sealing plate 10 is located outside the drying box 1, and a handle 11 is fixedly connected to the sealing plate 10.

[0039] The sealing plate 10 seals the material guide frame 8 and the side wall of the drying chamber 1, and the handle 11 makes it easy to pull out the material guide frame 8.

[0040] The working principle of the grain circulation dryer provided by this utility model is as follows:

[0041] By inserting the feeding assembly into the drying chamber 1, multiple sets of feeding assemblies are staggered, with the lower end of the upper feeding assembly located above the middle and upper end of the lower feeding assembly. The grain is discharged into the drying chamber 1 through the feed inlet 3 and rolls along the multiple sets of staggered inclined feeding assemblies. The hot air in the drying chamber 1 is discharged upward from the bottom of the drying chamber 1. The temperature inside the drying chamber 1 is high, and the grain is heated while rolling, resulting in uniform heating. After multi-layer rolling drying, the grain is finally discharged through the discharge plate 5. The grain in this dryer can be rolled and heated during the drying process, resulting in high drying efficiency, uniform heating, and automatic discharge.

[0042] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
