[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technical personnel in this field without creative work are within the scope of protection of the utility model.
[0021] See also Figures 1 to 4 The utility model provides a technical solution: a drying device with a waste heat recovery structure, including a box body 1, a second slide groove 3 is welded inside the box body 1, a fixing frame 4 is attached inside the second slide groove 3, a first slide groove 2 is welded on one side of the fixing frame 4, and a slide rail 5 is installed inside the box body 1 by screws.
[0022] A flue gas heat exchanger 101 is installed on the top of the box body 1 by screws, a water inlet pipe 108 is plugged into one side of the flue gas heat exchanger 101, and a safety valve 107 is plugged into the water inlet pipe 108 through a connecting pipe, a first heating variable frequency water pump 105 is plugged into one side of the safety valve 107, an exhaust valve 110 is plugged into one side of the first heating variable frequency water pump 105, and a first accumulator 104 is plugged into the other side of the exhaust valve 110, a water outlet pipe 109 is plugged into one side of the flue gas heat exchanger 101, a second accumulator 103 is plugged into one side of the water outlet pipe 109, a second heating variable frequency water pump 102 is plugged into one side of the second accumulator 103, and an exhaust pipe 106 is plugged into the rear of the flue gas heat exchanger 101.
[0023] In this embodiment, Figure 1 and Figure 4 As shown, a first motor 504 is attached to the bottom of the slide rail 5, a bevel gear 501 is inserted on one side of the first motor 504, the upper part of the bevel gear 501 is threadedly connected to the threaded rod 506, a slide rod 505 is inserted inside the slide rail 5, a slider 507 is inserted on one side of the slide rod 505, a second motor 502 is installed below the slider 507 by screws, a fan 503 is inserted on one side of the second motor 502, and the bevel gear 501 forms a rotating structure through the first motor 504, and the slider 507 forms a sliding structure with the bevel gear 501 and the threaded rod 506; a baking device without a mobile fan 503 may cause overheating. The amount is unevenly distributed inside the oven, which may cause the fungus to be heated unevenly in different positions. Some parts may be over-burned while other parts are not cooked through. The bevel gear 501 is rotated by the second motor 502. The bevel gear 501 is consistent with the thread of the threaded rod 506, so that the slider 507 moves inside the slider 505, and the first motor 504 moves with it, so as to facilitate the adjustment of the position of the fan 503. Moving the fan 503 can help distribute the hot air evenly inside the oven, thereby ensuring that the food is evenly heated throughout the baking process, which helps to avoid the problem of over-burning in some parts of the food and under-cooking in other parts.
[0024] In this embodiment, Figure 4 As shown, the fan 503 forms a rotating structure through the first motor 504; due to uneven heat distribution, the food may take longer to be completely baked, which may lead to an extension of the baking cycle and increase the time cost of the overall baking process. The first motor 504 rotates the fan 503, and the fan 503 moves with the moving device. Since the heat can be more evenly transferred to the surface of the food, the food can usually be completely baked in a shorter time, which helps to shorten the baking cycle and save time and energy costs.
[0025] In this embodiment, Figure 1 and Figure 2As shown, the external structural dimensions of the fixing frame 4 are consistent with the internal structural dimensions of the second slide groove 3, and the fixing frame 4 is integrally connected to the first slide groove 2; the fixing frame 4 can slide out from the second slide groove 3, and the baking tray can also slide out from the first slide groove 2. The disassembled fixing frame 4 is easy to clean and can be easily disassembled and cleaned, which can ensure that the baking device remains clean and hygienic, avoid the accumulation of food residues, and extend the service life of the equipment.
[0026] In this embodiment, Figure 3 As shown, the flue gas heat exchanger 101 is provided with an S-shaped pipe arranged on one side, and is respectively connected to the water inlet pipe 108 and the water outlet pipe 109, and the water inlet pipe 108 is provided with a plurality of connecting pipes, and the water inlet pipe 108 is connected to the safety valve 107, and the safety valve 107 is connected to the first heating variable frequency water pump 105, and the first heating variable frequency water pump 105 is connected to the exhaust valve 110, and the exhaust valve 110 is connected to the first energy storage device 104. The baking device without a waste heat utilization device will discharge a large amount of heat into the environment, causing energy waste. The hot air is sucked into the S-shaped pipe connected inside by the flue gas heat exchanger 101 for heating. The first energy storage device 104 is connected to the water source and sucked into the water inlet pipe 108 by the first heating variable frequency water pump 105. The safety valve 107 controls the pipe to be heated by the flue gas heat exchanger 101. The flue gas heat exchanger 101 can recover heat from the flue gas and transfer it to the medium that needs to be heated, such as water or air. This heat recovery can reduce energy consumption, improve energy utilization efficiency and reduce energy costs.
[0027] In this embodiment, Figure 3 As shown, the flue gas heat exchanger 101 is connected to the water outlet pipe 109, and the water outlet pipe 109 is connected to the second energy accumulator 103, and the second energy accumulator 103 is connected to the second heating variable frequency water pump 102; the heated water flows through the second heating variable frequency water pump 102 connected to the second energy accumulator 103, so that water flows out of the water outlet pipe 109 connected to the flue gas heat exchanger 101, and the waste heat utilization device can collect the waste heat generated during the baking process for easy utilization.
[0028] The use method and advantages of the utility model: When the drying device with waste heat recovery structure is used, the working process is as follows:
[0029] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, firstly, the unprocessed fungus is loaded and placed into the first slide 2 through a drying plate. The fixing frame 4 connected to the first slide 2 is horizontally inserted into the second slide 3 for drying. During baking, the bevel gear 501 is rotated clockwise by the first motor 504. The bevel gear 501 is threadedly connected to the threaded rod 506 to realize the horizontal movement of the slider 507. The second motor 502 rotates the fan 503 clockwise to facilitate the movement of the fan 503 so that the heat energy inside the oven is evenly distributed throughout the oven. After baking, the water in the first accumulator 104 is connected to the water inlet pipe 108 through the first heating frequency conversion water pump 105 and the safety valve 107. The flue gas heat exchanger 101 heats the water flow in the water inlet pipe 108, and the heated water flow is sucked out by the second heating frequency conversion water pump 102 connected to the second accumulator 103, and the exhaust gas is filtered through the filter net inside the exhaust pipe 106 and then discharged.
