Description

Technical Field

[0001] This utility model relates to a high-efficiency drying room. Background Technology

[0002] In the existing technology, drying rooms used for drying bamboo and wood chips and strips are generally set directly on cement floors, and the materials inside are dried by introducing hot air into the drying room.

[0003] While this type of drying room has the advantages of simple structure, low manufacturing cost, and adaptability to large-scale material drying, its disadvantages are also obvious: the material located at the bottom of the drying room, that is, close to the cement floor, cannot be effectively heated. It often results in the material at the top of the drying room being over-dried, while the material at the bottom of the drying room remains damp. This requires frequent stopping of drying and turning over the material in the drying room, resulting in low drying efficiency and wasting time and effort. Summary of the Invention

[0004] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a high-efficiency drying room that can make the materials in the drying room more uniformly heated, eliminates the need for manual turning of materials, and has a certain energy-saving effect.

[0005] The technical solution of this utility model is: a high-efficiency drying room, including a main body, a partition is provided inside the main body, the top of the partition and the top inside the main body are kept at a distance, and the partition divides the main body into a drying chamber and a return air channel;

[0006] The lower end of the partition is provided with an air outlet. A heat exchanger is fixed on the side of the air outlet facing the return air channel. The heat exchanger is connected to a steam generator through a connecting pipe. The lower end of the return air channel is also provided with a fan corresponding to the heat exchanger. The fan blows the heat from the heat exchanger into the drying chamber. After passing through the drying chamber, the hot air returns to the return air channel through the top of the partition and is then blown into the drying chamber by the fan, thus creating a cycle.

[0007] The bottom of the drying chamber is also provided with a tray, and the bottom of the tray is provided with a coil. The inlet end of the coil is connected to a heat exchanger. The steam and condensate in the heat exchanger exchange heat with the outside and then enter the coil. The waste heat of the steam and condensate is used to heat the bottom of the drying chamber before being discharged from the drying chamber.

[0008] Furthermore, the dried material is piled up on a tray, with the pile height being less than the height of the partition.

[0009] Furthermore, an exhaust port is also provided on the main body at the top of the drying chamber.

[0010] Furthermore, an electronic valve is provided on the exhaust port.

[0011] Furthermore, the drying chamber is also equipped with a hygrometer and a thermometer, and the hygrometer, thermometer, electronic valve and steam generator are connected to a controller.

[0012] Furthermore, a baffle is provided above the side of the air outlet facing the drying chamber.

[0013] Furthermore, the main body consists of an outer shell and an insulation layer disposed inside the outer shell.

[0014] Furthermore, the tray is densely covered with gaps.

[0015] Furthermore, the outlet end of the coil is connected to the water inlet of the steam generator.

[0016] Furthermore, the main body is also equipped with a sealing door.

[0017] The beneficial effects of this utility model are: the steam generator inputs high-temperature steam into the heat exchanger, the fan starts to blow the heat of the heat exchanger to the drying chamber, the hot air heats and dries the material in the drying chamber, the hot air that rises to the top of the drying chamber returns to the return air channel above the partition, and is then blown into the drying chamber by the fan, so that the temperature in the drying chamber rises rapidly and the residual heat in the hot air is fully utilized.

[0018] The high-temperature steam inside the heat exchanger partially condenses into liquid after passing through the heat exchanger. This condensate and steam still have a high temperature and are fed into the coils below the tray to heat the bottom of the drying chamber. This allows the material near the tray to be heated quickly and evenly, preventing the material at the top of the drying chamber from being over-dried while the material at the bottom of the drying chamber remains undried. It also makes full use of the waste heat from the steam and condensate, effectively improving drying efficiency and saving energy. Attached Figure Description

[0022] The technical solution of this utility model will be further described in detail below through embodiments and in conjunction with the accompanying drawings.

[0023] Combination Figure 1 and Figure 2As shown, a high-efficiency drying room includes a main body, and a partition 1 is provided inside the main body. The top of the partition 1 and the top of the main body are kept at a distance. The partition 1 divides the main body into a drying chamber 2 and a return air channel 3.

[0024] The lower end of the partition 1 is provided with an air outlet. A heat exchanger 4 is fixed on the side of the air outlet facing the return air channel 3. The heat exchanger 4 is connected to a steam generator through a connecting pipe. The lower end of the return air channel 3 is also provided with a fan 5 corresponding to the heat exchanger 4. The fan 5 blows the heat from the heat exchanger 4 towards the drying chamber 2. After passing through the drying chamber 2, the hot air returns to the return air channel 3 through the top of the partition 1 and is then blown towards the drying chamber 2 by the fan 5, and so on.

[0025] The bottom of the drying chamber 2 is also provided with a tray 6, and the bottom of the tray 6 is provided with a coil 7. The inlet end of the coil 7 is connected to the heat exchanger 4. The steam and condensate in the heat exchanger 4 exchange heat with the outside and then enter the coil 7. The waste heat of the steam and condensate is used to heat the bottom of the drying chamber 2 and then discharged from the drying chamber 2.

[0026] The working principle and beneficial effects of the above structure are as follows: The material to be dried (bamboo strips, bamboo chips, etc.) is placed in the drying chamber 2. The steam generator inputs high-temperature steam into the heat exchanger 4. The fan 5 starts to blow the heat from the heat exchanger 4 into the drying chamber 2. The hot air heats and dries the material in the drying chamber 2. The hot air that rises to the top of the drying chamber 2 returns to the return air channel 3 above the partition 1 and is then blown into the drying chamber 2 by the fan 5, so that the temperature in the drying chamber 2 rises rapidly and the residual heat in the hot air is fully utilized.

[0027] The high-temperature steam in heat exchanger 4 partially condenses into liquid after passing through heat exchanger 4. This condensate and steam still have a high temperature and are fed into the coil 7 below tray 6 to heat the bottom of drying chamber 2. This allows the material near tray 6 to be heated quickly and evenly, preventing the material at the top of drying chamber 2 from being over-dried while the material at the bottom of drying chamber 2 cannot be effectively dried. It also makes full use of the waste heat of steam and condensate, which can effectively improve drying efficiency and save energy.

[0028] In another embodiment, the material to be dried is piled on tray 6, and the pile height of the material is less than the height of partition 1, so as to ensure the drying effect of the material and avoid affecting the return of hot air.

[0029] In another embodiment, an exhaust port 8 is also provided on the main body at the top of the drying chamber 2.

[0030] In another embodiment, such as Figure 1 As shown, the exhaust port 8 is equipped with an electronic valve. When the humidity in the drying chamber 2 reaches a certain value, the exhaust port 8 opens to discharge the humid air in the drying chamber 2.

[0031] In another embodiment, the drying chamber 2 is also equipped with a hygrometer and a thermometer, and the hygrometer, thermometer, electronic valve and steam generator are connected to a controller to facilitate automated control.

[0032] In another embodiment, a baffle 9 is provided above the side of the air outlet facing the drying chamber 2 to increase the distance of the hot air blowing laterally, so that the material in the drying chamber 2 is heated more evenly.

[0033] In another embodiment, the main body consists of an outer shell 10 and an insulation layer 11 disposed within the outer shell 10.

[0034] In another embodiment, the tray 6 is densely covered with gaps to facilitate the upward dissipation of residual heat from steam or condensate in the coil 7.

[0035] In another embodiment, the outlet end of the coil 7 is connected to the inlet of the steam generator to recycle the water resources and residual heat in the condensate.

[0036] In another embodiment, the main body is also provided with a sealing door.
