Description

Technical Field

[0001] This utility model relates to the field of drying oven technology, specifically an energy-saving seed drying oven. Background Technology

[0002] A drying oven is a mechanical device that uses heat energy to reduce the moisture content of materials. It is used to dry objects. The dryer heats the material to vaporize and escape the moisture (generally water or other volatile liquid components) to obtain solid materials with a specified moisture content.

[0003] Hot air blows directly onto the seeds, causing nearby seeds to come into contact with the heat source first, while distant seeds come into contact with the heat source later, resulting in uneven drying. Secondly, in order to maintain a constant temperature, heat energy needs to be continuously injected into the drying chamber. Directly venting hot air outside the chamber results in a lot of heat waste and increases the energy consumption of the constant temperature forced-air drying chamber. Utility Model Content

[0004] The purpose of this section is to outline some aspects of the embodiments of this utility model and to briefly introduce some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of this section, the abstract, and the title, and such simplifications or omissions should not be used to limit the scope of this utility model.

[0005] 1. Technical problems to be solved:

[0006] To address the issues mentioned above, such as seeds closer to the heat source contacting it first while seeds further away contact it later, resulting in uneven drying, and the waste of heat due to directly venting hot air outside the chamber, thus increasing the energy consumption of the constant temperature forced-air drying oven, this utility model is proposed.

[0007] Therefore, the purpose of this invention is to provide an energy-saving seed drying box, which has the advantages of drying all seeds more evenly at the same time and allowing the hot air to be reused before being discharged into the air, thus achieving a certain energy-saving effect.

[0008] 2. Technical Solution:

[0009] To solve the above-mentioned technical problems, according to one aspect of the present invention, the present invention provides the following technical solution:

[0010] Energy-saving seed drying box, including:

[0011] A uniform drying assembly includes an outer casing, a first sealing door hinged to the outer casing, a drying chamber fixed at both ends to the inner wall of the outer casing, a second sealing door hinged to the drying chamber, air inlets symmetrically and evenly opened on the side walls of the drying chamber, a placement rack placed in the inner cavity of the drying chamber, a seed tray evenly placed on the placement rack, a heat source chamber fixed to the rear wall of the outer casing and communicating with the inner cavity of the outer casing, heating wires evenly installed in the inner cavity of the heat source chamber, a fixing plate fixed to the outer wall of the heat source chamber, and a blower fixed to the fixing plate and communicating with the inner cavity of the heat source chamber.

[0012] The energy-saving component includes an insulation frame welded and fixed to the outer wall of the outer casing, a hollow cavity opened inside the insulation frame, a heat collection air duct with one end connected to the hollow cavity and the other end connected to the drying chamber, an exhaust pipe connected to the insulation frame and communicating with the hollow cavity, and a one-way valve installed on the exhaust pipe.

[0013] As a preferred embodiment of the energy-saving seed drying box of this utility model, L-shaped support legs are symmetrically fixed on the side wall of the outer box.

[0014] As a preferred embodiment of the energy-saving seed drying box described in this utility model, it also includes a rotating component disposed at the bottom of the insulation frame, which can drive the placement rack to rotate.

[0015] As a preferred embodiment of the energy-saving seed drying box of this utility model, the rotating assembly includes a rotating rod rotatably mounted on the insulation frame and fixed to the bottom of the placement rack, a gear fixed on the rotating rod, a second fixing plate fixed to the bottom of the insulation frame, an electric push rod fixed on the second fixing plate, and a rack fixed on the electric push rod and meshing with the gear.

[0017] As a preferred embodiment of the energy-saving seed drying box of this utility model, the placement rack is provided with symmetrical slots, and the seed tray is inserted into the slots.

[0018] As a preferred embodiment of the energy-saving seed drying box described in this utility model, a support frame is fixed at the bottom of the heat source chamber.

[0019] 3. Beneficial effects:

[0020] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0021] 1. Compared with the traditional method of directly blowing hot air onto seeds, which results in uneven drying because seeds closer to the surface are exposed to the hot air first and seeds farther away are exposed later, this energy-saving seed drying box has evenly spaced air inlets on both sides of the drying box. This allows hot air to enter the inner cavity of the drying box from a row of air inlets, so that the seed trays and seeds located on both sides and at the top and bottom can be exposed to the hot air more simultaneously, resulting in more uniform drying.

[0022] Second, this type of energy-saving seed drying box, without an insulation frame, would have its outer wall directly exposed to the cold air outside. However, with an insulation frame, the hot air entering the box has a temperature higher than that of the outside air, which can provide a certain insulation effect for the outer box. This reduces the heat exchange between the drying box and the outer box and the cold air outside, thus making the whole device energy-saving. Attached Figure Description

Detailed Implementation

[0030] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0031] Figures 1-5 The diagram shown is a structural schematic of one embodiment of the energy-saving seed drying box of this utility model. Please refer to [link / reference]. Figures 1-5 The present invention is an energy-saving seed drying box, the main body of which includes a uniform drying component 100 and an energy-saving component 200.

[0032] The uniform drying assembly 100 includes an outer casing 110, a first sealing door 110a hinged to the outer casing 110, a drying chamber 120 welded and fixed to the inner wall of the outer casing 110 at both ends, a second sealing door 120a hinged to the drying chamber 120, air inlets 120b symmetrically and evenly opened on the side walls of the drying chamber 120, a placement rack 130 placed in the inner cavity of the drying chamber 120, seed trays 140 evenly placed on the placement rack 130, a heat source chamber 150 welded and fixed to the rear wall of the outer casing 110 and communicating with the inner cavity of the outer casing 110, and seeds evenly installed in the heat source chamber 150. The inner cavity contains an electric heating wire 160, a fixing plate 170 welded and fixed to the outer wall of the heat source chamber 150, and a blower 180 fixed to the fixing plate 170 by bolts and connected to the inner cavity of the heat source chamber 150. A support frame 190 is fixed at the bottom of the heat source chamber 150. The blower 180 blows the heat generated by the electric heating wire 160 into and gradually fills the inner cavity of the outer box 110. The hot air will finally enter the inner cavity of the drying box 120 from the air inlet 120b. Because the air inlet 120b is opened on the two side walls of the drying box 120, the hot air can contact all the seed trays 140 relatively evenly.

[0033] The energy-saving component 200 includes an insulation frame 210 welded and fixed to the outer wall of the outer casing 110, a hollow cavity 220 opened inside the insulation frame 210, a heat collection air duct 230 connected at one end to the hollow cavity 220 and at the other end to the drying chamber 120, an exhaust pipe 240 connected to the insulation frame 210 and communicating with the hollow cavity 220, and a one-way valve 250 installed on the exhaust pipe 240. Without the insulation frame 210, the outer wall of the outer casing 110 would be in direct contact with the cold air outside. With the insulation frame 210, the insulation frame 210 has a temperature higher than that of the air because hot air is introduced into it, which can play a certain role in heat preservation for the outer casing 110, thereby enabling the entire device to achieve a certain energy-saving effect.

[0034] Furthermore, to enable the placement rack 130 and seed tray 140 to rotate, allowing the seeds to rotate and be heated more evenly, specifically, L-shaped support legs 110b are symmetrically fixed to the side wall of the outer casing 110, allowing the outer casing 110 to be lifted off the ground; the device also includes a rotating assembly 300, located at the bottom of the insulation frame 210, capable of driving the placement rack 130 to rotate. The rotating assembly 300 includes a rotating rod 310 rotatably mounted on the insulation frame 210 and fixed to the bottom of the placement rack 130, a gear 320 fixed to the rotating rod 310 via a keyway and spline, and a welding... The insulation frame 210 is fixed with a second fixing plate 330 at the bottom, an electric push rod 340 is fixed to the second fixing plate 330 by bolts, and a rack 350 is fixed to the electric push rod 340 by threads and meshes with the gear 320. The rack 350 has a limit hole 360. A limit rod 370 inserted into the limit hole 360 ​​is welded and fixed to the bottom of the insulation frame 210. During the rotation of the seed tray 140, the seeds in the seed tray 140 rotate with it, so that the inner and outer seeds can adjust their positions to each other, so that all seeds can be dried more evenly.

[0035] Finally, to make the seed tray 140 easy to install and remove, the placement rack 130 is provided with symmetrical slots 130a. The seed tray 140 is inserted into the slots 130a. After opening the second sealing door 120a, the seed tray 140 can be pulled out directly.

[0036] Combination Figures 1-5 The specific implementation method of this energy-saving seed drying box is as follows:

[0037] 1. First, open the first sealing door 110a, then open the second sealing door 120a, place the seeds on the seed tray 140, then close the first sealing door 110a and the second sealing door 120a, then turn on the blower 180 and energize the heating wire 160. The heating wire 160 generates heat, which is blown by the blower 180 along the heat source chamber 150 into the inner cavity of the outer box 110. Then the hot air enters the inner cavity of the drying box 120 through the air inlet 120b. Because the air inlet 120b is opened on both side walls of the drying box 120, the hot air can contact all the seed trays 140 relatively evenly.

[0038] 2. Then the hot air will take away the moisture on the seeds and enter the hollow cavity 220 from the heat collection air pipe 230 at the top, so that the entire temperature frame 210 is heated by the hot air, so that the exterior of the outer box 110 has a certain heat preservation effect, thereby preventing the external cold air from directly contacting the outer wall of the outer box 110, reducing the heat loss of the outer box 110, thus achieving a certain energy-saving effect. Finally, the hot air is discharged from the exhaust pipe 240.

[0039] 3. Finally, turn on the electric push rod 340 to move the rack 350, drive the gear 320 and the rotating rod 310 to rotate, drive the placement rack 130 and the seed tray 140 to rotate, so that the seeds on the inner and outer sides of the seed tray 140 can exchange positions, so that the seeds in all positions can be in contact with the hot air more evenly.
