Description

Technical Field

[0001] This utility model belongs to the technical field of medicinal material drying equipment, and specifically relates to a heat circulation drying room based on a modular circulating fan. Background Technology

[0002] Currently, the processing of Chinese medicinal herbs involves many steps, such as washing, slicing, stir-frying, drying, testing, and packaging. For herbs requiring drying, a heat-circulating drying chamber is generally used. In existing technology, the structure of a heat-circulating drying chamber is typically designed as a box-type structure. Inside this chamber, a dedicated material chamber is set up for placing the herbs to be dried. To achieve the drying function, a heating system is designed on one side of the material chamber, and a fan assembly consisting of four or six circulating fans is installed on the other side. The operation of these fans promotes air circulation within the drying chamber, thereby achieving uniform heat distribution and efficient utilization.

[0003] However, in such drying rooms, the installation method for multiple circulating fans in the fan assembly is generally to directly fix one end of the fan to the air wall panel and the other end to the fan frame with multiple bolts. When it is necessary to install or remove the circulating fans, two people need to work together to complete the task. One person holds and supports the circulating fan while the other person removes and installs the bolts one by one. The installation and removal process for a single fan is already very time-consuming and labor-intensive. For multiple circulating fans, the time and physical effort are multiplied many times over, which urgently needs to be solved. Utility Model Content

[0004] This utility model addresses the shortcomings of existing technologies by providing a heat circulation drying room based on a modular circulating fan. The specific technical solution is as follows:

[0005] This utility model provides a heat circulation drying room based on a modular circulating fan, including a box-type drying room with a material chamber inside. A heating system is connected to one side of the material chamber, and a fan assembly is installed on the other side. The fan assembly includes a wind wall plate that is embedded and fitted with the corresponding port of the material chamber. The wind wall plate has six circular air inlets arranged in a rectangular array. A fan frame is fixedly connected to the back of the wind wall plate. Three suspension members are suspended longitudinally at equal intervals on the inner side of the fan frame. A circulating fan is radially fitted in each of the suspension members, and the air outlet of the circulating fan is axially abutted against the corresponding air inlet. The air inlet of the circulating fan is integrally fitted with an annular flange.

[0006] A pressure plate is hinged to the outer opening of the fan frame. The pressure plate has six circular air intakes arranged in a rectangular array. A rubber ring is fixed to the inner end of each air intake along the axial direction. The pressure plate is fixed to the fan frame by a matching fastener, and the rubber ring abuts against the annular flange of the corresponding circulating fan.

[0007] As a preferred technical solution of this utility model, the suspension component includes a first connector with an I-shaped structure. The ends of the first connector are respectively radially symmetrically fixed with circular support rings. The circular support rings are axially engaged with the outer shell of the corresponding circulating fan. The outer side of the circular support ring is radially fixed with a second connector with an I-shaped structure. The second connector is vertically connected to the inner side of the corresponding fan frame by bolts that are adapted to it.

[0008] As a preferred embodiment of this utility model, a circular end ring is fixedly connected axially inside the air inlet, and the end ring is engaged with the end of the corresponding circulating fan.

[0009] As a preferred technical solution of this utility model, a reinforcing grille is integrally fixed to the outer opening of the fan frame, and each square opening of the reinforcing grille is axially opposite to the corresponding circulating fan.

[0010] As a preferred technical solution of this utility model, the inner side of the fan frame is provided with a square ring structure baffle in an integrated circumferential direction facing the edge of the wind wall panel; the baffle is fixedly screwed to the end face of the corresponding material chamber by bolts that are compatible with it.

[0011] As a preferred embodiment of this utility model, the top surface of the drying chamber is integrated with a waste heat recovery chamber, and a waste heat recovery system adapted to it is provided in the middle of the waste heat recovery chamber; a dehumidifying fan is vertically connected between the chamber facing the heating system and the material chamber of the waste heat recovery chamber, and a dehumidifying outlet is provided on the top surface of the chamber on the other side; the waste heat generated by the waste heat recovery system enters the drying chamber through the waste heat return outlet provided on the side of the dehumidifying fan.

[0012] The beneficial effects of this utility model are:

[0013] In this utility model of a heat circulation drying chamber, the circulating fan is radially mounted inside the fan frame via a suspension component, and the air inlet on the pressure plate cooperates with the air outlet of the circulating fan. A rubber ring and annular flange are used to achieve a tight fit, and the pressure plate is then fixed by a buckle. This method greatly simplifies the installation and disassembly process, eliminating the need to disassemble and assemble bolts one by one. Only the buckle needs to be operated, saving time and effort.

[0014] The simplified installation and disassembly process allows for rapid maintenance or replacement of the circulating fan, improving the maintenance efficiency of the drying room. This also helps reduce production losses caused by downtime for maintenance.

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this utility model.

[0025] Example 1

[0026] To address the technical problems in the background section, the following heat circulation drying room based on a modular circulating fan is proposed:

[0027] Combination Figures 1-4As shown, a heat circulation drying room based on a modular circulating fan includes a drying room 1 with a box structure. The drying room 1 is divided into a material chamber 11. A heating system 2 is connected to one side of the material chamber 11, and a fan assembly 3 is installed on the other side. The fan assembly 3 includes a wind wall plate 31 that is embedded and fitted with the corresponding port of the material chamber 11. The wind wall plate 31 has six circular air inlets 311 arranged in a rectangular array. A fan frame 32 is fixedly connected to the back of the wind wall plate 31. Three suspension members 33 are suspended longitudinally at equal intervals on the inner side of the fan frame 32. A circulating fan 34 is radially fitted in each of the suspension members 33. The air outlet of the circulating fan 34 is axially abutted with the corresponding air inlet 311. The air inlet is integrally fitted with an annular flange 341.

[0028] A pressure plate 35 is hinged to the outer opening of the fan frame 32. The pressure plate 35 has six circular air intakes 352 arranged in a rectangular array. A rubber ring 351 is fixedly connected to the inner end of the air intake 352 along the axial direction. The pressure plate 35 is fixedly attached to the fan frame 32 by a matching fastener 353, and the rubber ring 351 abuts against the annular flange 341 of the corresponding circulating fan 34.

[0029] By adopting the above technical solution, the circulating fan 34 in the heat circulation drying chamber is radially clamped in the fan frame 32 by the suspension member 33, and the air inlet 352 on the pressure plate 35 cooperates with the air outlet of the circulating fan 34. The rubber ring 351 and the annular flange 341 are used to achieve tight connection, and the pressure plate is fixed by the fastener 353. This method greatly simplifies the installation and disassembly process, eliminating the need to disassemble and install bolts one by one. Only the fastener needs to be operated, saving time and effort.

[0030] Due to the simplified installation and disassembly process, maintenance or replacement of the circulating fan 34 can be completed quickly, improving the maintenance efficiency of the drying room 1; this also helps to reduce production losses caused by downtime for maintenance.

[0031] The circulating fan 34 is modularly mounted on the fan frame 32, allowing for easy replacement of different models or performance levels of the circulating fan 34 as needed, thus upgrading and optimizing the drying room 1. At the same time, the modular design also makes maintenance and replacement more flexible and convenient.

[0032] Example 2

[0033] Combination Figures 1 to 7 As shown, based on the above embodiments, this embodiment further provides the following:

[0034] In this embodiment, as Figure 5 and Figure 6As shown, the suspension member 33 includes an I-shaped connector 331. The ends of the connector 331 are respectively radially symmetrically fixed with circular support rings 332. The circular support rings 332 are axially engaged with the outer shell of the corresponding circulating fan 34. The outer side of the circular support rings 332 is radially fixed with an I-shaped connector 333. The connector 333 is vertically connected to the inner side of the corresponding fan frame 32 by bolts that are adapted to it.

[0035] By adopting the above technical solution, the suspension component 33 uses an I-shaped connector 331 as the main body. The ends of the connector 331 are respectively radially symmetrically fixed with circular support rings 332. These circular support rings 332 are axially engaged with the outer shell of the circulating fan 34, ensuring the stable installation of the circulating fan 34 on the fan frame 32.

[0036] Through the design of the suspension component 33, the circulating fan 34 can be quickly installed on the fan frame 32 in a modular manner, and can also be easily disassembled; this modular design makes it possible to simply remove the circulating fan 34 from the circular support ring 332 when maintenance or replacement is required, which greatly simplifies the maintenance process and improves work efficiency.

[0037] Connector 2 333 is vertically connected to the inner side of the fan frame 32 by bolts. This connection method is not only firm and reliable, but also convenient for later disassembly and replacement.

[0038] like Figures 4-7 As shown, a circular end ring 312 is fixedly connected axially inside the air inlet 311, and the end ring 312 is engaged with the end of the corresponding circulating fan 34.

[0039] By adopting the above technical solution, the end ring 312 serves as an axial fixing structure within the air inlet 311, forming a snap-fit ​​with the end of the circulating fan 34. This design not only simplifies the installation process and avoids the tediousness of precise alignment and individual tightening of bolts in the traditional bolt fixing method, but also enhances the connection stability between the circulating fan 34 and the wind wall plate 31.

[0040] The snap-fit ​​between the end ring 312 and the end of the circulating fan 34 also provides a good sealing effect. During the drying process, hot air enters the material chamber 11 through the heating system 2 and the heat is evenly distributed through the operation of the circulating fan 34. The sealing design of the end ring 312 can better prevent hot air from leaking out from the gap between the circulating fan 34 and the air wall plate 31, thereby improving the temperature uniformity and drying efficiency in the drying room 1.

[0041] like Figure 4 , Figure 6 and Figure 7As shown, a reinforcing grille 322 is integrally fixed to the outer opening of the fan frame 32, and each square opening of the reinforcing grille 322 is axially opposite to the corresponding circulating fan 34.

[0042] By adopting the above technical solution, the reinforced grille 322 is integrally fixed to the outer opening of the fan frame 32, with its square grid openings axially opposite to the corresponding circulating fan 34. This design significantly enhances the structural strength of the fan frame 32, enabling it to withstand greater loads and vibrations. During the drying process, the circulating fan 34 operates at high speed, generating vibrations and noise. The presence of the reinforced grille 322 effectively absorbs and disperses these vibrations, preventing the fan frame 32 from deforming or being damaged due to prolonged stress, thereby extending the service life of the equipment.

[0043] like Figures 1-4 as well as Figure 6 , Figure 7 As shown, a square ring structure baffle 321 is integrally arranged on the inner side of the fan frame 32 facing the edge of the wind wall plate 31; the baffle 321 is fixedly screwed to the end face of the corresponding material chamber 11 by bolts that are compatible with it.

[0044] By adopting the above technical solution, the baffle 321 serves as an integrated circumferential structure on the inner side of the fan frame 32 facing the edge of the wind wall plate 31. Its square ring design enhances the connection stability between the fan assembly 3 and the wind wall plate 31. Through the bolt fixing connection between the baffle 321 and the end face of the material chamber 11, the fan assembly 3 is more firmly installed in the drying room 1, effectively preventing loosening or falling off due to vibration or external force, thereby ensuring the normal operation of the drying room and the drying efficiency.

[0045] The baffle 321 is fixedly connected to the end face of the material chamber 11 by bolts, which makes it easy to remove the blower assembly 3 from the material chamber 11 for maintenance and replacement; this design not only improves work efficiency, but also reduces maintenance costs.

[0046] Example 3

[0047] Combination Figure 1 As shown, based on the above embodiments, this embodiment further provides the following:

[0048] In this embodiment, as Figure 1 As shown, the top surface of the drying room 1 is integrally equipped with a waste heat recovery chamber 12, and a waste heat recovery system 5 adapted to it is set in the middle of the waste heat recovery chamber 12; a dehumidifying fan 4 is vertically connected between the chamber facing the heating system 2 and the material chamber 11, and a dehumidifying port 13 is set on the top surface of the chamber on the other side; the waste heat generated by the waste heat recovery system 5 enters the drying room 1 through the waste heat return port 14 set on the side of the dehumidifying fan 4.

[0049] By adopting the above technical solution, the waste heat recovery system 5 can extract waste heat from the humid air generated during the drying process. During the drying process of Chinese medicinal materials, a large amount of heat is discharged with the humid air. Through the waste heat recovery system 5, this heat can be captured and converted into usable thermal energy. This thermal energy can be reused for heating in the drying room 1, thereby reducing the energy consumption of the heating system 2 and improving the overall energy utilization efficiency.

[0050] The design of the waste heat return port 14 allows the waste heat generated by the waste heat recovery system 5 to be directly returned to the drying chamber 1, further utilizing the recovered heat. This not only reduces energy waste but also improves the temperature stability within the drying chamber, contributing to the uniform drying of the Chinese medicinal materials.

[0051] The dehumidification fan 4 is responsible for extracting the hot and humid air generated during the drying process from the material chamber 11. This helps to reduce the humidity in the material chamber 11, accelerate the drying speed of Chinese medicinal materials, and reduce the risk of deterioration of Chinese medicinal materials due to excessive humidity.

[0052] The vent 13 ensures that humid air can be smoothly discharged from the drying chamber 1, avoiding the accumulation of humid air in the drying chamber 1. This helps maintain air circulation in the drying chamber 1 and improves drying efficiency.

[0053] With the combined use of the waste heat recovery system 5 and the waste heat return outlet 14, the temperature inside the drying room 1 can be maintained more stably within a suitable range; this stable temperature environment helps the Chinese medicinal materials to dry evenly and avoids the problem of uneven drying caused by temperature fluctuations.

[0054] The synergistic effect of the dehumidification fan 4 and the dehumidification port 13 effectively controls the humidity in the drying room 1; this humidity control helps the Chinese medicinal materials maintain their original quality and medicinal properties during the drying process, thus improving the drying quality.

[0055] By recovering and reusing waste heat, this technology significantly reduces energy consumption during the drying process; this not only lowers production costs but also aligns with the current environmental protection concept of energy conservation and emission reduction.

[0056] Working principle and usage process of this utility model:

[0057] In use, the medicinal herbs to be dried are first placed in the material chamber 11. Then, the heating system 2 is started to provide heat to the material chamber 11. At the same time, the fan assembly 3 starts to work, and the circulating fan 34 draws in air through its air inlet, heats it, and blows hot air out from its air outlet. The hot air enters the material chamber 11 through the air inlet 311 to dry the medicinal herbs.

[0058] In the fan assembly 3, the circulating fan 34 is radially secured within the suspension member 33, which is fixedly connected to the fan frame 32 via connector 1 331 and connector 2 333. This design simplifies the installation and disassembly of the circulating fan 34, eliminating the need for two people and significantly improving work efficiency. Simultaneously, the pressure plate 35 is fixedly attached to the fan frame 32 via a snap fastener 353, and the rubber ring 351 abuts against the annular flange 341 of the circulating fan 34. This not only prevents the circulating fan 34 from falling off but also enhances the sealing of the fan assembly 3, preventing hot air leakage.

[0059] During the drying process, the Chinese medicinal materials generate heat-containing moisture, which is introduced into the waste heat recovery chamber 12 through the dehumidification fan 4. Fresh air exchanges heat with the heat-containing moisture in the waste heat recovery system 5. The moisture is discharged to the outside through the dehumidification port 13, while the heat is recovered into the drying room 1 through the waste heat return port 14 for recycling. This ensures that the temperature of the drying room 1 is stable during dehumidification and improves the drying quality of the medicinal materials.

[0060] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
