Abstract
Description
Technical Field
[0001] This utility model belongs to the field of agricultural and sideline product drying technology, specifically relating to a new type of drying and dehydration equipment. Background Technology
[0002] Some agricultural and sideline products require initial processing after harvesting before packaging and sale. Some agricultural and sideline products need to be dried after harvesting due to moisture content. The initial processing of agricultural and sideline products includes a drying process, and the efficiency and cost of drying directly determine the processing cost of the agricultural products.
[0003] Some existing drying equipment uses fuel combustion to heat air, and then uses fans or air pumps to send the high-temperature gas into the drying chamber to heat the agricultural products inside the drying chamber.
[0004] In existing equipment, some of the heat generated during combustion during drying is discharged from the exhaust pipe along with the flue gas, resulting in energy waste due to heat loss. This leads to low drying efficiency and low heat utilization in the combustion chamber. To improve the heat utilization rate in the exhaust pipe, the inventors have proposed a new type of drying and dehydration equipment. Utility Model Content
[0005] The technical problem to be solved by this utility model is that some of the heat generated by combustion during drying is discharged from the exhaust pipe along with the flue gas, resulting in energy waste. In view of the shortcomings of the existing technology, a new type of drying and dehydration equipment is provided.
[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:
[0007] The device includes a dehydration tank, a thermal energy component, and an induced draft fan. The thermal energy component is detachably installed inside the dehydration tank. The dehydration tank has a housing chamber for accommodating the thermal energy component. The thermal energy component includes a combustion chamber. The exhaust port of the combustion chamber is connected to a single continuous tortuous pipe for conducting the heat generated by combustion in the combustion chamber to the interior of the housing chamber. A panel is installed on the front of the combustion chamber. The tortuous pipe forms a stacked frame by periodically reciprocating along the top of the combustion chamber through the single continuous pipe. Two adjacent stacked frames are connected by end extensions to form an axial stack. The induced draft fan is connected to the thermal energy component and is used to drive the heat from the combustion chamber to move along the tortuous pipe.
[0008] Furthermore, the thermal energy assembly also includes an ash collection box located outside the combustion chamber, with its inlet connected to the flue gas outlet of the combustion chamber and its outlet connected to the inlet of a tortuous pipe.
[0009] Furthermore, an ash box is fixedly connected to the bottom of the combustion chamber, and a grille is provided at the bottom of the combustion chamber.
[0010] Furthermore, a dust removal chamber is fixedly connected to the panel, the tortuous path of the convoluted pipe is connected to the dust removal chamber, and a dust removal chamber cover is provided on the front of the dust removal chamber.
[0011] Furthermore, the induced draft fan is fixedly installed on the top of the dehydration tank, and a sleeve is slidably installed inside the air inlet of the induced draft fan, with one end of the sleeve connected to the outlet of the tortuous pipe.
[0012] Furthermore, the dehydration box is equipped with a drying chamber for drying agricultural and sideline products. The storage chamber is connected to the drying chamber. The drying chamber is equipped with shelves and shelves with shelves. The front of the drying chamber is equipped with a door.
[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0014] 1. The design, combining a combustion chamber with a single, tortuous pipe, transfers the heat generated by combustion to the drying chamber via a continuous, circuitous path, effectively extending the heat residence time in the system and improving heat utilization. Simultaneously, the detachable design of the thermal components facilitates maintenance and cleaning, further enhancing the equipment's operating efficiency. By optimizing the heat transfer path and improving the heat utilization rate of the combustion chamber, energy consumption is significantly reduced, thereby lowering the cost of primary processing of agricultural products.
[0015] 2. In traditional drying equipment, a large amount of heat is discharged with the flue gas, resulting in energy waste. This utility model, through the design of the ash collection box, effectively separates and centrally treats the smoke and dust generated in the combustion chamber, avoiding the impact of smoke and dust on the pipeline and the environment inside the drying chamber, while reducing heat loss;
[0016] 3. The induced draft fan is fixed to the top of the dehydration tank and connected to the outlet of the tortuous pipe through a sleeve, which can efficiently drive the airflow and make the high-temperature gas evenly distributed inside the drying chamber. Combined with the multi-layer structure design of shelves and plates, the heat exchange efficiency of agricultural products in the drying chamber is further improved, and the drying time is shortened.

Detailed Implementation
[0024] To better understand this utility model, the following embodiments further illustrate its content, but the scope of protection of this utility model is not limited to the embodiments described below. Numerous specific details are set forth in the following description to provide a more thorough understanding of this utility model. However, it will be apparent to those skilled in the art that this utility model can be practiced without one or more of these details.
[0025] Example 1: See Figure 1-5 This embodiment of a novel drying and dehydration device includes a dehydration tank 10, a thermal energy component 20, and an induced draft fan 30. The thermal energy component 20 is detachably installed inside the dehydration tank 10.
[0026] The dehydration tank 10 has an internal chamber 11 for housing the thermal energy component 20;
[0027] The thermal energy component 20 includes a combustion chamber 21. The exhaust port of the combustion chamber 21 is connected to a single continuous tortuous pipe 22 for conducting the heat generated by combustion in the combustion chamber 21 to the interior of the housing 11. A panel 23 is installed on the front of the combustion chamber 21. The design of the combustion chamber combined with the tortuous pipe extends the time of the flue gas in the single tortuous pipe 22, allowing more heat to be transferred to the dehydration tank 10 through the inner wall of the single tortuous pipe 22. This improves the heat utilization efficiency when drying and dehydrating agricultural and sideline products inside the dehydration tank 10.
[0028] The single tortuous pipe 22 forms a single-layer stacked frame along the top of the combustion chamber 21 through a continuous forward and reverse meandering path. The two adjacent stacked frames are spliced together by extending their ends. In this embodiment, the single tortuous pipe 22 is spliced together sequentially with square boxes as ends at the end away from the panel 23. Arc-shaped pipes can also be used as ends for splicing. The choice is made according to production cost and appearance, and there is no restriction here. The heat generated by combustion is transferred to the drying chamber through a continuous meandering path. The continuous meandering design makes the structure of the thermal energy component 20 more compact and reduces the size of the device.
[0029] The induced draft fan 30 is connected to the thermal energy component 20. The induced draft fan 30 is used to drive the heat of the combustion chamber 21 to move along the tortuous pipe 22. The setting of the induced draft fan can efficiently drive the airflow and avoid the flue gas not being able to enter the pipe due to the excessive length of the single tortuous pipe 22, so that the high temperature gas is evenly distributed inside the dehydration tank.
[0030] See Figure 3 The thermal energy component 20 also includes an ash collection box 24 located outside the combustion chamber 21. The inlet of the ash collection box 24 is connected to the exhaust port of the combustion chamber 21, and the outlet is connected to the inlet of the tortuous pipe 22. A large amount of dust in the flue gas adheres to the inner wall of the ash collection box, which can reduce the amount of dust entering the tortuous pipe and centrally treat the dust generated in the combustion chamber, avoiding the accumulation of dust in the tortuous pipe. At the same time, the ash collection box is located outside the combustion chamber, which can reduce the direct heat loss from the combustion chamber and avoid the formation of local high temperatures inside the dehydration box. The drying heat is more evenly distributed. Through the design of the ash collection box, the dust generated in the combustion chamber is effectively separated and centrally treated, avoiding the impact of dust on the pipe and the environment inside the drying chamber.
[0031] See Figure 2-5 An ash box 26 is fixedly connected to the bottom of the combustion chamber 21. A grid 27 is provided at the bottom of the combustion chamber 21. After the firewood burns in the combustion chamber 21, the ash enters the ash box 26 through the grid 27 for collection, so that the firewood burns completely and facilitates airflow.
[0032] See Figure 1 The induced draft fan 30 is fixedly installed on the top of the dehydration tank 10. A sleeve 31 is slidably installed inside the air inlet of the induced draft fan 30. One end of the sleeve 31 is inserted into the outlet of the tortuous pipe 22. Moving the sleeve 31 can connect and disconnect the tortuous pipe 22 from the induced draft fan 30. After separation, the heat energy component 20 can be separated from the dehydration tank 10. The modular design makes maintenance relatively convenient.
[0033] See Figure 1The dehydration chamber 10 has a drying chamber 12 for drying agricultural products. The receiving chamber 11 is connected to the interior of the drying chamber 12. The drying chamber 12 has shelves 13 with shelves 14 on them. The front of the drying chamber 12 has a door 15. High-temperature gas is evenly distributed inside the drying chamber. The multi-layer structure design of the shelves and shelves further improves the heat exchange efficiency of agricultural products in the drying chamber and shortens the drying time.
[0034] Beneficial effects:
[0035] 1. The design, combining a combustion chamber with a single, tortuous pipe, transfers the heat generated by combustion to the drying chamber via a continuous, circuitous path, effectively extending the heat residence time in the system and improving heat utilization. Simultaneously, the detachable design of the thermal components facilitates maintenance and cleaning, further enhancing equipment operating efficiency. By optimizing the heat transfer path and improving the heat utilization rate of the combustion chamber, energy consumption is significantly reduced, thereby lowering the cost of primary processing of agricultural products.
[0036] 2. The rational design and installation position of the induced draft fan (such as fixing it to the top of the dehydration tank and connecting it to the outlet of the tortuous pipe through a sleeve) can efficiently drive the airflow, so that the high-temperature gas is evenly distributed inside the drying chamber. Combined with the multi-layer structure design of the shelves and plates, the heat exchange efficiency of agricultural products in the drying chamber is further improved, and the drying time is shortened.
[0037] Example 2: Example 2 is a further improvement based on Example 1. See [link / reference] Figure 2-5 In this embodiment, a novel drying and dehydration device is provided. A dust removal chamber 28 is fixedly connected to the back of the panel 23. The opening of the dust removal chamber 28 is provided on the panel 23. The tortuous path connection part of the tortuous pipe 22 is connected to the dust removal chamber 28. The interior of the dust removal chamber 28 is provided with a partition to allow the single tortuous pipe 22 to flow one-to-one in a specific path in sequence. A dust removal chamber cover 281 is provided on the front of the dust removal chamber 28. The dust removal chamber cover 281 is hinged to the front of the panel 23 to keep the opening of the dust removal chamber closed when covered.
[0038] Beneficial effects
[0039] In traditional drying equipment, a large amount of heat is discharged with the flue gas, resulting in energy waste. This invention, through the design of an ash collection box and a cleaning chamber, effectively separates and centrally treats the smoke and dust generated in the combustion chamber, avoiding the impact of smoke and dust on the pipelines and the environment inside the drying chamber, while reducing heat loss.
