Description

Technical Field

[0001] This utility model relates to the field of grain drying towers, and more particularly to a device for recycling the thermal energy of a grain drying tower. Background Technology

[0002] The selection and configuration of grain drying towers and grain drying towers are based on the relative movement direction of grain and airflow. Dryers can be divided into cross-flow, mixed-flow, co-flow, counter-flow, co-counter-flow, co-counter-flow, mixed-counter-flow, and co-mixed-flow types.

[0003] For example, the patent application with patent number CN204317076U in the prior art has the advantages of saving grain drying costs and solving the problem of difficult grain drying. It is not only suitable for large-tonnage grain storage, but also for medium and small-tonnage grain storage and small-scale storage by farmers. It has great promotion value. The heat preservation structure reduces the impact of external sunlight on the grain inside the grain storage tower.

[0004] However, heat needs to be continuously supplied to the tower. It can only keep the heat inside the tower warm and cannot be recycled. Over time, some heat will still be lost, thus increasing energy consumption.

[0005] Therefore, it is necessary to provide a grain drying tower heat energy recycling device to solve the above-mentioned technical problems. Utility Model Content

Detailed Implementation

[0017] To make the above-mentioned objectives, features and advantages of this utility model more readily understood, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0018] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0019] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single embodiment or an embodiment selectively excluded from other embodiments.

[0020] Example 1: Please see Figures 1-4 This is the first embodiment of the present utility model. This embodiment provides a heat energy recycling device for a grain drying tower, applied to a drying tower 1; it includes a top cover 2, which is disposed on the top of the drying tower 1, and a circulation device 9 is disposed on the inner side of the top cover 2; Copper tube 6 is fixedly connected to the bottom of the inner side of the top cover 2. Arc-shaped heat absorption tubes 7 are fixedly connected to the surface of copper tube 6. There are ten copper tubes 6 and twenty arc-shaped heat absorption tubes 7. Cavity 5 is located inside the drying tower 1, and ventilation holes 10 are provided on the inner side of cavity 5 and on the inner wall of drying tower 1.

[0021] The circulation device 9 includes a fixed cavity 91, a fan 94 is fixedly installed on the top of the inner side of the fixed cavity 91, and a heat sink 92 is fixedly installed on the bottom of the fan 94 and inside the fixed cavity 91.

[0022] A connecting copper pipe 93 is fixedly connected to the outer side of the bottom of the heat sink 92. The bottom of the connecting copper pipe 93 is fixedly connected to the top of the copper pipe 6. There are ten connecting copper pipes 93.

[0023] The top of the drying tower 1 is fixedly connected to the air inlet pipe 3, and one end of the air inlet pipe 3 is fixedly connected to the hot air output device 4. The bottom of the drying tower 1 is fixedly connected to three support legs.

[0024] A drying device 8 is fixedly connected to the bottom of the inner side of the top cover 2. The drying device 8 includes a hollow tube 81. Several vent holes 82 are opened on the outer surface of the hollow tube 81. An insertion tube 83 is fixedly connected to the bottom of the hollow tube 81.

[0025] Example 2: Please see Figures 4-5 This is the second embodiment of the present utility model.

[0026] Specifically, by using the tube 83 with a pointed bottom, the drying device 8 can enter the drying tower 1 when grain is stored in the drying tower 1, thus reducing resistance.

[0027] An insulation blanket 11 is fixedly connected to the outer surface of the drying tower 1.

[0028] The insulation blanket 11 can effectively reduce the heat loss of the drying tower 1, while the use of the arc-shaped heat absorption tube 7 can have a large contact area to adsorb and conduct heat. The material of the arc-shaped heat absorption tube 7 is copper.

[0029] The heat sink 92 is hollow arc-shaped, and the hollow tube 81 runs through the entire top cover 2 and passes through the fixed cavity 91.

[0030] The cavity 5 is located inside the drying tower 1, and a ventilation hole 10 is provided on its inner side and on the inner wall of the drying tower 1. The ventilation hole 10 facilitates the flow of heat and air in the tower, promoting the drying of grains.

[0031] The insulation blanket 11 is located on the outer surface of the drying tower 1, which can reduce the heat loss from the tower to the outside, further improve the heat utilization rate, and maintain the temperature stability inside the tower.

[0032] The top cover 2 serves to close and support the top device.

[0033] The air inlet pipe 3 is fixedly connected to the top of the drying tower 1, and one end of its outer side is connected to the hot air output device 4, which is the channel for hot air to enter the drying tower 1.

[0034] The fixed cavity 91 is the main frame of the circulation device 9.

[0035] The fan 94 blows heat off the heat sink 92 by running, thus promoting heat circulation.

[0036] The heat sink 92 is located at the bottom of the fan 94 and inside the fixed cavity 91. It is hollow and arc-shaped. It is connected to the connecting copper pipe 6 and the heat sink 92. It receives and stores the heat conducted through the copper pipe 6 and then dissipates the heat through the fan 94.

[0037] There are ten copper pipes 93 connected together. The bottom of the pipe is fixedly connected to the top of the copper pipe 6, and the top is connected to the outer side of the bottom of the heat sink 92, forming a heat conduction path from the copper pipe 6 to the heat sink 92.

[0038] Copper pipes 6 are fixedly connected to the bottom inside the top cover 2, and there are ten of them. Arc-shaped heat absorbers 7 are fixedly connected to their surfaces, which are the main channels for heat conduction.

[0039] There are twenty arc-shaped heat absorption tubes 7, which are fixedly connected to the surface of copper tube 6, increasing the contact area with the hot gas inside the tower and improving the heat absorption efficiency.

[0040] The hollow tube 81 runs through the entire top cover 2 and through the fixed cavity 91, and is fixedly connected to the bottom with an insertion tube 83. Several vent holes 82 are opened on the outer surface of the hollow tube 81, which are channels for hot air distribution and circulating heat to enter the drying tower 1.

[0041] Ventilation holes 82 are distributed on the outer surface of the hollow tube 81. Several ventilation holes 82 ensure that hot air can be evenly distributed into the drying tower 1, and at the same time facilitate the re-entry of circulating heat into the tower.

[0042] In summary, hot air is generated by the hot air output device 4 and conducted to the drying device 8 through the air inlet pipe 3. Therefore, the hot air enters the hollow tube 81 and is dispersed in the drying tower 1 through the air vent 82 to dry the grain.

[0043] As the heat in the drying tower 1 gradually increases, the heat is absorbed through the arc-shaped heat absorption pipe 7, and conducted through the copper pipe 6 and connecting copper pipe 93 to the heat sink 92. Then, the fan 94 is activated to blow the heat out of the heat sink 92, filling the fixed cavity 91. The heat then enters the hollow tube 81 through the vent 82 in the drying device 8, and then enters the drying tower 1 again through the vent 82, thus repeating the cycle. Therefore, the hot air output device 4 can provide heat indirectly, thereby reducing energy consumption. At the same time, the drying tower 1 can maintain a certain temperature for a longer period of time to dry the grain.
