Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery related to crop processing, specifically a batch grain dryer. Background Technology

[0002] Before grains are harvested and stored or processed into food, they need to be dried. Drying is the most common drying method. The necessity of grain drying is mainly reflected in the following two aspects: First, it ensures grain quality. The drying process removes excess moisture from the grains, reducing the risk of mold and bacterial growth, thus ensuring grain quality and safety. Second, it extends storage time. High moisture content in grains easily leads to spoilage during storage, while drying effectively reduces the moisture content, thereby extending their shelf life. Furthermore, drying reduces the time and likelihood of grains becoming damp, minimizing storage losses.

[0003] In practice, although traditional drying equipment can replace manual drying, it still suffers from poor drying effect and low drying efficiency. Summary of the Invention

[0004] In order to overcome the shortcomings of traditional grain drying, this utility model proposes a batch grain dryer.

[0005] The technical problem to be solved by this utility model is achieved by the following technical solution:

[0006] A batch grain dryer includes a combustion furnace and several drying chambers; a heat transfer pipe connects the combustion furnace and each drying chamber. Hot air is introduced into each combustion furnace through the heat transfer pipe to dry the grain.

[0007] Each drying chamber is equipped with a grain channel; the grain channel consists of a vertical channel and an inclined channel connecting to the top of the vertical channel; a batch control component is installed within the vertical channel. After the grain is fed into the drying chamber, it travels along the path within the grain channel to complete the drying process. The batch control component directs the fed grain through the drying area on the left side of the inclined channel in batches, resulting in a relatively better drying effect.

[0008] Each drying chamber has two discharge ports on its front side; each drying chamber has an inclined feeding bin installed on its rear side, and each inclined feeding bin has a sealing component on its right end. The inclined feeding bin and the discharge ports are used to facilitate the feeding of grains and the collection of grains after drying, respectively. The sealing component is used to close the right end of the inclined feeding bin before the drying process begins.

[0009] The beneficial effects of this utility model are:

[0010] 1. Multiple drying chambers can be used for simultaneous drying, which effectively improves the drying speed and efficiency.

[0011] 2. Grains are fed into the inclined channel in batches by pushing, which effectively controls the amount of grains to be dried each time and reduces the factors that cause insufficient heat absorption due to mutual obstruction between grains, resulting in a relatively better drying effect.

[0012] 3. By controlling the speed at which the grain moves in the inclined channel and limiting the diameter of the pipe opening on the left side of the inclined channel, the drying effect can be further improved. Attached Figure Description

[0020] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be described more clearly and completely below with reference to the accompanying drawings in the embodiments. Of course, the described embodiments are only a part of the present utility model and not all of them. Based on this embodiment, other embodiments obtained by those skilled in the art without creative effort are all within the protection scope of this utility model.

[0021] like Figure 1As shown, a batch grain dryer includes a combustion furnace 1 and several drying chambers 2; a heat transfer pipe 3 connects the combustion furnace 1 and each drying chamber 2. Hot air is introduced into each combustion furnace 1 through the heat transfer pipe 3 to dry the grain. A control panel is also provided on the front of the combustion furnace 1 for easy manual control of the hot air delivery volume and temperature.

[0022] like Figures 3 to 5 As shown, each drying chamber 2 is equipped with a grain channel 7; the grain channel 7 consists of a vertical channel 71 and an inclined channel 72 connected to the top of the vertical channel 71; a batch control component is installed inside the vertical channel 71. After the grain is fed into the drying chamber 2, it travels along the path within the grain channel 7 to complete the drying process. The batch control component is used to guide the fed grain through the drying area on the left side of the inclined channel 72 in batches, resulting in a relatively better drying effect.

[0023] like Figure 1 and Figure 2 As shown, each drying chamber 2 has two discharge ports 2a on its front side; each drying chamber 2 has an inclined feeding bin 4 installed on its rear side, and the right end of the inclined feeding bin 4 is equipped with a sealing component. The inclined feeding bin 4 and the discharge ports 2a are used to facilitate the feeding of grains and the collection of grains after drying. The sealing component is used to close the right end of the inclined feeding bin 4 before the drying process begins.

[0024] like Figure 5 As shown, the tilting delivery chamber 4 has a notch 4a on its upper right side; the sealing assembly consists of a sealing plate 5 slidably installed at the notch 4a and a cylinder 6 connected to the sealing plate 5. That is, the cylinder 6 can control the sealing plate 5 to slide to open or close the right end of the tilting delivery chamber 4.

[0025] like Figure 5 As shown, cylinder 6 is fixedly installed on the inner wall of the drying chamber 2. The above is a conventional design for a fixed installation structure.

[0026] like Figure 5 As shown, the vertical channel 71 has an inclined feed port 71a connected to the right end of the inclined feeding bin 4 at the middle left side; the batch control component consists of a hydraulic cylinder 8 installed at the bottom of the vertical channel 71 and an upward push block 9 connected to the hydraulic cylinder 8; the upward push block 9 is slidably installed in the vertical channel 71. That is, grain can enter the vertical channel 71 through the inclined feeding bin 4, and by pushing the upward push block 9 upward, a portion of the grain can enter the inclined channel 72 through the vertical channel 71.

[0027] like Figure 5As shown, a ventilation duct 10 is provided between the left side of the inclined channel 72 and the heat transfer pipe 3, connecting the two. Several ventilation holes 72a, connected to the ventilation duct 10, are evenly distributed on the upper side of the seat of the inclined channel 72. Hot air enters the inclined channel 72 sequentially through the heat transfer pipe 3, the ventilation duct 10, and the ventilation holes 72a, heating the grain passing through the inclined channel 72 to evaporate moisture and achieve drying. The diameter of the ventilation holes 72a is relatively small compared to the grain, ensuring that the grain cannot pass through the ventilation holes 72a.

[0028] like Figure 5 As shown, the upper end of the push block 9 is provided with an inclined surface 9a; both the inclined surface 9a and the left part of the inclined channel 72 have an angle of 15 degrees with the horizontal plane. The inclined surface 9a ensures that when the push block 9 is pushed upward, the grain can slide into the inclined channel 72. The smaller horizontal angle makes the grain slide to the lower right in the inclined channel 72 at a relatively low speed, ensuring that there is enough time to dry it thoroughly.

[0029] like Figure 5 As shown, both discharge ports 2a are connected to the right side of the inclined channel 72; the inner diameter of the left side of the inclined channel 72 is 1 cm. The smaller diameter of the left side of the inclined channel 72 ensures that the number of grains passing through each movement is small, the space between grains is less obstructed, and the heating area is large, resulting in a relatively better drying effect.

[0030] The specific method of using this utility model is as follows:

[0031] Step 1: Manually put the grains that need to be dried into the inclined feeding bin 4. The grains will automatically slide into the vertical channel 71 under the action of gravity.

[0032] Step 2: Cylinder 6 pushes down the sealing plate 5 to seal the right end of the tilted delivery chamber 4.

[0033] Step 3: The hydraulic cylinder 8 pushes the pusher block 9 upwards, causing a portion of the grain to enter the inclined channel 72. As this portion of grain moves through the inclined channel 72, hot air passes sequentially through the heat transfer pipe 3, the ventilation pipe 10, and the air vent 72a, thus drying this portion of grain. The dried grain then enters the right side of the inclined channel 72.

[0034] Step 4: Repeat step 3 above to dry all the grains. After drying, the grains can be manually removed through the discharge port 2a.

[0035] 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 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.
