Description

Technical Field

[0001] The utility model relates to the technical field of a circulating drying room, in particular to a drying room adopting a two-way hot air circulation. Background Art

[0002] A drying room refers to equipment that dries designated items. High-temperature air is sent into the drying room to evaporate and dry the moisture on the items. It is also one of the main methods of drying now. There are many types of drying rooms, which are mainly classified according to different drying methods. The most common drying rooms are hot air circulation types. This type of drying room can evenly distribute heat on each item due to the hot air, ensuring uniformity of drying. The hot air can also take away the steam in the air to ensure a dry environment inside the drying room.

[0003] However, hot air circulation is generally a one-way circulation. If the product is blown in one direction for a long time, the side that contacts the hot air will heat up first, while the temperature of the back will gradually increase. There is a temperature difference in this process. Although it can ensure uniform heating, it takes time. This will cause problems for the products due to the temperature difference. For this reason, a baking room with two-way hot air circulation is set up. Utility Model Content

DETAILED DESCRIPTION

[0014] The utility model will be further described below in conjunction with the accompanying drawings.

[0015] Please refer to Figure 1-3 The utility model adopts a bidirectional hot air circulation baking room, comprising a baking room 1, a processing box 3 is set up on one side of the baking room 1, a recovery box 4 is set up between the processing box 3 and the baking room 1, two collecting pipes 5 are fixedly connected to the side wall of one side of the recovery box 4, the recovery box 4 is connected and communicated with the baking room 1 through the collecting pipe 5, a connecting pipe 2 is fixedly connected to the side wall opposite to the baking room 1, the end of the connecting pipe 2 away from the processing box 3 is inserted and extended into the baking room 1, an air supply groove 11 is opened in the processing box 3, a drying area 7 is opened in the baking room 1, and a partition 8 is fixedly connected to the inner wall of the drying area 7 close to the recovery box 4, and the ends of the connecting pipe 2 and the collecting pipe 5 extending into the baking room 1 are respectively located on both sides of the partition 8.

[0016] The technical effect of this solution is as follows: hot air is blown into the drying zone 7 from both sides through the connecting pipe 2, and the two streams of hot air flow in opposite directions so that both sides of the articles can be heated and dried at the same time, thus avoiding temperature difference. Similarly, because the two streams of hot air flow relative to each other, they will eventually collide, thus generating turbulence, which can effectively increase the residence time of the hot air in the drying zone 7, improve the heating effect of the hot air in the drying zone 7, and improve the drying efficiency. The blown hot air can be recovered through the collecting pipe 5 and then sent to the processing box 3 for recycling, thus saving energy consumption.

[0017] A storage tank 12 is provided in the recovery box 4, and the storage tank 12 is communicated with the interior of the baking room 1 through the collecting pipe 5. An isolation plate is fixedly connected to the side wall below the storage tank 12. An air pump 13 is detachably connected to the recovery box 4, and the air pump 13 is communicated with the storage tank 12 through a pipeline. The air outlet end of the air pump 13 is fixedly connected to a delivery pipe 6, and one end of the delivery pipe 6 extends into the bottom of the processing box 3. The top side wall of the delivery pipe 6 is evenly and detachably connected with an air outlet nozzle 10. The processing box 3 has a side wall located below the air supply tank 11, which is evenly and detachably connected with a heating mesh plate 9. The air supply tank 11 is communicated with the interior of the baking room 1 through the connecting pipe 2. One side of the top of the air supply tank 11 is an arc structure, and three heating mesh plates 9 are evenly inlaid with electric heating pipes.

[0018] The technical effect of this scheme is as follows: the hot air blown out enters the storage tank 12 along the collecting pipe 5, and then the air in the storage tank 12 is sent to the processing box 3 through the air pump 13. The air rises and passes through the three heating mesh plates 9 to heat the air, and finally enters the connecting pipe 2 through the air supply groove 11, and finally is discharged into the drying area 7 along the connecting pipe 2, thereby realizing the circulation of air and ensuring that the air temperature is within the required range to ensure the drying effect.

[0019] Specifically, when the utility model is used, the air pump 13 is started to extract the air accumulated in the storage tank 12 and send it into the processing box 3 through the conveying pipe 6, and then the air is blown upward and discharged through the air outlet nozzle 10. As the air rises, it will pass through the heating mesh plate 9. The heating mesh plate 9 is started in advance to raise its temperature to a higher temperature than the preset value, and then the air passing through the heating mesh plate 9 will be heated, and the heated air will enter the drying area 7 along the connecting pipe 2 and flow in the drying area 7. Because the three pairs of connecting pipes 2 are set up, the function of relative flow of two hot air can be realized, thereby improving the heating efficiency and avoiding temperature difference on both sides of the article. Secondly, the two relative hot air will produce impact, thereby generating turbulence to increase the residence time of the hot air and improve the heating effect.

It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.

Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
