Abstract
Description
Technical Field
[0001] This utility model relates to the field of lily processing technology, and in particular to a high-efficiency hot air circulating oven for drying lilies. Background Technology
[0002] In the lily processing industry, drying is a key step in ensuring the stability of lily storage and extending its shelf life. However, existing drying boxes use a fixed air duct design, and hot air diffuses indiscriminately inside the box, making it impossible to dynamically adjust according to the placement of materials. When multiple material racks are set inside the box, even if only some racks are filled with lilies, hot air will continue to flow into the remaining unfilled areas, resulting in a large amount of heat being wasted and causing serious energy waste. Utility Model Content
[0003] This utility model addresses the shortcomings of existing technologies by providing the following technical solution:
[0004] A high-efficiency hot air circulating oven for drying lilies, including:
[0005] Drying oven;
[0006] The placement component includes two sets of fixed frames symmetrically arranged inside the drying oven, a locking block fixedly arranged on opposite sides of the fixed frame, and an adjusting member disposed within the locking block. The side walls of the fixed frame and both sides of the locking block are provided with multiple sets of ventilation holes, and the adjusting member can slide within the locking block.
[0007] A placement net is provided, with inserts fixedly installed on both sides of the placement net;
[0008] A circulation component is used to drive hot air to circulate evenly inside the drying chamber. Its air outlet is connected to the inside of the fixed frame, and its air inlet is connected to the inside of the drying chamber.
[0009] Specifically, the insertion block is controlled to be inserted into the card block, and the adjustment component is controlled to move, thereby opening the vent hole.
[0010] As an improvement to the above technical solution, the adjusting component includes a movable rod movably disposed between the fixed frame and the locking block. A movable plate is fixedly disposed at one end of the movable rod located inside the locking block, and a sealing plate is fixedly connected to the other end of the movable rod located inside the fixed frame. A spring is wound around the surface of the movable rod and the section located inside the locking block.
[0011] As an improvement to the above technical solution, the multiple sets of ventilation holes on the side wall of the fixed frame located on both sides of the card block are all oriented towards the plane where the net is placed.
[0012] As an improvement to the above technical solution, the circulation component includes a hot air blower installed on the side wall of the drying chamber. The drying chamber is connected to the air inlet end of the hot air blower by an air inlet pipe, and the air outlet end of the hot air blower is connected to an air outlet pipe. The air outlet pipe is connected to the inside of the fixed frame through a branch pipe.
[0013] The beneficial effects of this utility model are:
[0014] By linking the placement components with the adjustment components, the ventilation holes are opened only when the placement net is present, allowing hot air to act precisely on the material area. In areas where no lilies are placed, the ventilation holes are closed, and hot air will not flow through them ineffectively. This "on-demand air supply" mode effectively solves the problem of indiscriminate diffusion of hot air in traditional fixed air ducts, and greatly reduces the heat loss in non-material areas.

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.
[0020] A high-efficiency hot air circulating oven for drying lilies, including:
[0021] Drying oven 10;
[0022] The placement component includes two sets of fixed frames 40 symmetrically arranged inside the drying oven 10, a locking block 42 fixedly arranged on opposite sides of the fixed frame 40, and an adjusting member disposed in the locking block 42. The sidewalls of the fixed frame 40 and both sides of the locking block 42 are provided with multiple sets of ventilation holes 46. The adjusting member can slide in the locking block 42.
[0023] A placement net 30 is provided, and insert blocks 31 are fixedly provided on both sides of the placement net 30;
[0024] A circulation component is used to drive hot air to circulate evenly within the drying chamber 10. Its air outlet is connected to the interior of the fixed frame 40, and its air inlet is connected to the interior of the drying chamber 10.
[0025] Specifically, the insertion block 31 is inserted into the card block 42, and the adjustment component is moved to open the vent 46.
[0026] Specifically, the circulation component extracts and heats the air from the drying chamber 10, then sends it into the fixed frame 40 from the air outlet. When the insert 31 is not inserted into the locking block 42, the adjusting component closes the vent 46, reducing the air volume and allowing the air volume to flow out from the position where the placement net 30 is installed. The inserts 31 on both sides of the placement net 30 containing lilies are inserted into the locking block 42. The inserts push the adjusting component to slide within the locking block 42, thereby removing the obstruction of the vent 46 by the adjusting component. The hot air acts directly on the lilies in the placement net through the opened vent 46, carrying away moisture, thus achieving uniform coverage of the lilies with hot air and improving drying efficiency. The air that has completed heat exchange flows back through the air inlet of the circulation component, is reheated, and re-enters the circulation, forming a closed loop of "heating → air supply → drying → recirculation", improving heat utilization.
[0027] In one embodiment, the adjusting member includes a movable rod 41 movably disposed between the fixed frame 40 and the locking block 42. A movable plate 43 is fixedly disposed at one end of the movable rod 41 inside the locking block 42, and a sealing plate 44 is fixedly connected to the other end of the movable rod 41 inside the fixed frame 40. A spring 45 is wound around the surface of the movable rod 41 and the section inside the locking block 42. When the locking block 42 is not inserted with the insert 31, [reference needed]. Figure 3 When the spring 45 is in a naturally extended state, it applies a pushing force to the moving plate 43, causing the moving plate 43 to move the movable rod 41. The sealing plate 44 at the other end of the movable rod 41 thus fits tightly against the inner wall of the fixed frame 40 and covers the ventilation holes 46 on both sides of the block 42, sealing the ventilation holes 46. At this time, the communication between the inside of the fixed frame 40 and the drying chamber 10 is blocked, reducing the ineffective flow of hot air when there is no material.
[0028] Align the inserts 31 on both sides of the lily-filled netting 30 with the clips 42 on the fixing frame 40 and insert them, for reference. Figure 2Furthermore, a pushing force is applied to the movable plate 43. Under the action of the pushing force, the movable plate 43 overcomes the elastic force of the spring 45 and drives the movable rod 41 to slide synchronously. The sealing plate 44 at the other end of the movable rod 41 moves with the movable rod 41 and gradually gets rid of the obstruction of the vent 46, so that the inside of the fixed frame 40 is connected to the inside of the drying oven 10 through the vent 46. Hot air diffuses to both sides through the vent 46 and blows directly onto the lilies in the placement net 30, quickly removing moisture.
[0029] In one embodiment, multiple sets of ventilation holes 46 on the side wall of the fixed frame 40 located on both sides of the card block 42 face the plane where the placement net 30 is located. Because the ventilation holes 46 face the placement net 30, hot air will be ejected from the ventilation holes 46 along a directional path and act obliquely on the surface of the lily, forming a double-sided sandwich-type air supply, thereby achieving full-coverage drying of the lily material.
[0030] In one embodiment, the circulation assembly includes a hot air blower 20 installed on the side wall of the drying chamber 10. The drying chamber 10 is connected to the air inlet end of the hot air blower 20 by an air inlet pipe 22, and the air outlet end of the hot air blower 20 is connected to an air outlet pipe 21. The air outlet pipe 21 is connected to the interior of the fixed frame 40 through a branch pipe 211. After the hot air blower 20 is started, its internal heating element (such as an electric heating wire) heats the air drawn in. The heated hot air enters the air outlet pipe 21 from the air outlet end of the hot air blower 20, and then enters the interior of the fixed frame 40 symmetrically arranged on both sides through multiple branches 211 branched from the air outlet pipe 21. The air that has completed the drying process flows through the internal space of the drying chamber 10 and is finally drawn in by the air inlet end of the hot air blower 20 through the air inlet pipe 22. The return air is reheated by the hot air blower 20 and re-enters the air outlet pipe 21 for circulation.
[0031] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it.
