Abstract
Description
Technical Field
[0001] This utility model relates to the field of electrical engineering technology, and in particular to an automated drying device. Background Technology
[0002] Drying is a very common and crucial process in electrical engineering and related industrial production and daily life, and is widely used in food processing, textile printing and dyeing, wood processing, agricultural product processing and household appliances.
[0003] Currently used drying equipment usually relies on hot air to come into contact with the items to be dried. However, relying solely on hot air has low thermal conductivity, and the center of some larger items is difficult to dry. The outer skin of the items will dry after prolonged contact with hot air, which hinders the release of moisture from the inside of the items and results in uneven drying. Summary of the Invention
[0004] This invention provides an automated drying device that ensures the center of the item is heated and dried while allowing moisture to dissipate outwards, resulting in more uniform drying.
[0005] In a first aspect, this utility model provides an automated drying device, specifically comprising: a drying cabinet; two cabinet doors are rotatably mounted on the front side of the drying cabinet via hinges; an air inlet pipe is fixed to the top right side of the drying cabinet, a set of item holders is connected to the bottom of the air inlet pipe, and a set of air outlet pipes is connected to the bottom of the item holders; a set of lower brackets is fixed to the bottom inner side of the drying cabinet; an air outlet pipe is fixed to the top left side of the drying cabinet, and an air outlet hood is fixed to the top inner side of the drying cabinet, with the air outlet hood communicating with the bottom end of the air outlet pipe.
[0006] The lower bracket also has several strip-shaped openings in the middle, and the round holes on the air outlet pipe are all located directly below the openings in the middle of the lower bracket.
[0007] The item holder has an overall S-shaped curved structure, and the overall width of the item holder is equal to the width of the inner cavity of the drying cabinet. Moreover, the inner cavity of the item holder is connected to the air inlet pipe and the air outlet pipe.
[0008] The air inlet pipe is a trapezoidal pipe with a narrow top and a wide bottom in the middle. A cylindrical rod is fixed inside the lower part of the air inlet pipe, and the outer diameter of the cylindrical rod is 2cm smaller than the width of the cavity inside the air inlet pipe.
[0009] The main body of the item holder consists of three rows of horizontally arranged square tubes, which are interconnected by vertical rectangular tubes. A slot is provided between each of the adjacent horizontal square tubes on the front and back of the item holder.
[0010] The air outlet hood is a hollow cylindrical hood with an opening in the middle of the bottom, and the air outlet hood is located in the middle of the top inner wall of the drying cabinet.
[0011] The top outer wall of the air outlet pipe is provided with several through-holes at equal intervals, and the lower bracket is located above the air outlet pipe.
[0012] This utility model provides an automated drying device, which has the following beneficial effects:
[0013] The item holder in this invention can not only transport hot air to dry the items, but also support the items that need to be dried. Therefore, when the hot air flows in the item holder, it can directly conduct heat to the items that need to be dried through the outer wall of the item holder. The direct heat conduction method is more conducive to the heat transfer to the center of the items, and the contact area with the items is also relatively small, so the outer skin of the items will not be completely dried. This ensures that the center of the items is heated and dried, and allows the moisture to dissipate outward, resulting in more uniform drying. Attached Figure Description

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the described embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0026] Example 1: Please refer to Figures 1 to 6 :
[0027] This utility model proposes an automated drying device, including: a drying cabinet 1; two cabinet doors 2 are hinged and installed on the front side of the drying cabinet 1; the internal cavity of the drying cabinet 1 is used to dry the items to be dried; the cabinet doors 2 are used to cover the opening at the front of the drying cabinet 1; an air inlet pipe 3 is fixed to the top right side of the drying cabinet 1; a set of item holders 4 are connected to the bottom of the air inlet pipe 3; and a set of air outlet pipes 5 are connected to the bottom of the item holders 4. When the hot air blower is working, the hot air generated will first enter the air inlet pipe 3 and flow downward. During this process, the hot air will contact the cylindrical rod inside the lower part of the air inlet pipe 3, and then the hot air can only flow downward through the gap on the outside of the cylindrical rod, thus dispersing and guiding the hot air to make it flow evenly. Subsequently, the hot air will enter the cavity inside the item holders 4 and flow downward. During this process, the hot air... Part of the heat in the air is transferred to the item holder 4, thus allowing the item holder 4 to initially heat the items placed on top of it. When the hot air flows to the inside of the air outlet pipe 5, it will be sprayed upward through the round hole at the top of the air outlet pipe 5. Then, the hot air will flow upward through the opening slot in the middle of the lower bracket 6 and between the adjacent horizontal square tubes on the front and back of the item holder 4, so that the hot air can evenly contact the items to be dried, thereby achieving the drying effect. A set of lower brackets 6 is fixed to the inner bottom of the drying cabinet 1, which is used to support the items to be dried. An air outlet pipe 7 is fixed to the left side of the top of the drying cabinet 1, and an air outlet hood 8 is fixed to the inner top of the drying cabinet 1. The air outlet hood 8 is connected to the bottom end of the air outlet pipe 7. The air outlet pipe 7 and the air outlet hood 8 can introduce the air in the drying cabinet 1 into the external dryer for recycling.
[0028] In this embodiment, as Figure 2 and Figure 4As shown, the lower bracket 6 is also provided with several strip-shaped opening slots in the middle, and the round holes on the air outlet pipe 5 are all located directly below the opening slots in the middle of the lower bracket 6. When hot air flows into the inside of the air outlet pipe 5, it will be sprayed upward through the round holes at the top of the air outlet pipe 5. Then the hot air will flow upward through the opening slots in the middle of the lower bracket 6, so that it can evenly contact the items that need to be dried.
[0029] In this embodiment, as Figure 2 and Figure 3 As shown, the item holder 4 has an overall S-shaped curved structure. The overall width of the item holder 4 is equal to the width of the inner cavity of the drying cabinet 1. Moreover, the inner cavity of the item holder 4 is connected to the air inlet pipe 3 and the air outlet pipe 5. When the hot air blower is working, the hot air generated will first enter the air inlet pipe 3 and flow downward. Then, the hot air will enter the inner cavity of the item holder 4 and flow downward. During this process, some of the heat in the hot air will be transferred to the item holder 4, so that the item holder 4 can initially heat the items placed on top of it. Then, the hot air will continue to flow downward into the air outlet pipe 5 and be sprayed outward.
[0030] In this embodiment, as Figure 3 and Figure 5 As shown, the middle part of the air inlet pipe 3 is a trapezoidal pipe that is narrower at the top and wider at the bottom. A cylindrical rod is fixed inside the lower part of the air inlet pipe 3, and the outer diameter of the cylindrical rod is 2cm smaller than the width of the cavity inside the air inlet pipe 3. When the hot air blower is working, the hot air generated will first enter the air inlet pipe 3 and flow downward. During this process, the hot air will come into contact with the cylindrical rod inside the lower part of the air inlet pipe 3. Then the hot air can only flow downward through the gap on the outside of the cylindrical rod, so the hot air can be dispersed and guided to flow evenly.
[0031] In this embodiment, as Figure 2 and Figure 3 As shown, the main body of the item holder 4 consists of three rows of horizontally arranged square tubes. The three rows of square tubes are interconnected by vertical rectangular tubes. There is a slot between each of the adjacent horizontal square tubes on the front and back of the item holder 4. When in use, the items to be dried can be placed on top of the horizontal square tubes on the item holder 4. During the drying process, hot air will enter the cavity inside the item holder 4 and flow downward. During this process, some of the heat in the hot air will be transferred to the item holder 4, so that the item holder 4 can preheat the items placed on top of it. Moreover, the hot air in the cavity inside the drying cabinet 1 can also flow upward through the slots between the adjacent horizontal square tubes on the front and back of the item holder 4.
[0032] In this embodiment, as Figures 2-4As shown, several through-holes are evenly spaced on the top outer wall of the air outlet pipe 5, and the lower bracket 6 is located above the air outlet pipe 5. When hot air flows into the inner side of the air outlet pipe 5, it will be sprayed upward through the through-holes at the top of the air outlet pipe 5. Then, the hot air will flow upward through the opening groove in the middle of the lower bracket 6 and between the adjacent horizontal square tubes on the front and back of the item holder 4, so that the hot air can come into uniform contact with the items to be dried, thereby achieving the drying effect.
[0033] Example 2, based on Example 1, such as Figures 1-6 As shown, the air outlet hood 8 is a hollow cylindrical hood with an opening in the middle of the bottom. The air outlet hood 8 is located in the middle of the top inner wall of the drying cabinet 1. When the external hot air blower is working, it will draw air in through the air outlet pipe 7. At this time, the air in the cavity inside the drying cabinet 1 will first enter the cavity inside the air outlet hood 8 through the opening in the middle of the bottom, and then be drawn into the external hot air blower through the air outlet pipe 7 for recycling. Therefore, heat loss can be reduced.
[0034] The working principle of this embodiment is as follows: During installation, the drying cabinet 1 can be placed in the drying workshop. Then, the air inlet pipe 3 is connected to the air outlet of the external hot air blower, and the air outlet pipe 7 is connected to the air inlet of the external hot air blower. When items need to be dried, the two cabinet doors 2 can be opened first, and then the items to be dried can be placed on the top of the horizontal square tube and the top of the lower bracket 6 on the item holder 4. Then, the two cabinet doors 2 are closed again. At this time, the external hot air blower can be powered on and operated. The hot air generated by the hot air blower will first enter the air inlet pipe 3 and flow downward. During this process, the hot air will contact the cylindrical rod inside the lower part of the air inlet pipe 3. Then, the hot air can only flow downward through the gap on the outside of the cylindrical rod, thus dispersing and guiding the hot air to make it flow evenly. Subsequently, the hot air will enter the item holder 4. The hot air flows downwards into the cavity on the side. During this process, some of the heat in the hot air is transferred to the item holder 4, thus enabling the item holder 4 to preheat the items placed on top. When the hot air flows to the inside of the air outlet pipe 5, it will be sprayed upwards through the round hole at the top of the air outlet pipe 5. Then, the hot air will flow upwards through the opening slot in the middle of the lower bracket 6 and between the adjacent horizontal square tubes on the front and back of the item holder 4, so that the hot air can come into uniform contact with the items to be dried, thereby achieving the drying effect. When the external hot air fan is working, it will draw air in through the air outlet pipe 7. At this time, the air in the cavity inside the drying cabinet 1 will first enter the cavity inside through the opening in the middle of the bottom of the air outlet hood 8, and then be drawn into the external hot air fan through the air outlet pipe 7 for recycling, which can reduce heat loss.
