Description

Technical Field

[0001] This utility model belongs to the field of constant temperature and humidity cabinets, and specifically relates to a flour storage and transportation integrated constant temperature and humidity cabinet. Background Technology

[0002] As a consumable, flour's quality assurance during storage and transportation is crucial, primarily by maintaining a stable and uniform constant temperature and humidity environment. If a constant temperature and humidity cabinet relies solely on simple fans for direct blowing or unidirectional circulation, the short and uneven airflow path easily creates persistent temperature and humidity "dead zones" within the cabinet. This unevenness leads to the risk of flour clumping or spoilage in certain areas. Furthermore, this crude airflow pattern makes the entire system slow to respond to environmental changes. When the cabinet door is opened or the external environment fluctuates, the system struggles to quickly recover and maintain its set stable state, resulting in continuous large fluctuations in internal environmental parameters (such as temperature and humidity). Therefore, we aim to design an integrated constant temperature and humidity cabinet for flour storage and transportation to solve this problem. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an integrated constant temperature and humidity cabinet for flour storage and transportation, so as to solve the problems mentioned in the background technology.

[0004] This utility model is achieved through the following technical solution: a flour storage and transportation integrated constant temperature and humidity cabinet, comprising: a cabinet body, the interior of which is filled with a heat insulation layer composed of urethane foam, a cover plate hinged to the upper end of the cabinet body, an inner liner fixedly connected to the interior of the cabinet body, and an internal circulation constant temperature and humidity module for maintaining a stable environment inside the cabinet body.

[0005] The internal circulation constant temperature and humidity module includes several sets of axial flow fans set on the bottom side inside the cabinet, an air duct formed between the inner liner and the cabinet, a guide plate one fixedly connected to the outer surface of the inner liner, and a guide plate two fixedly connected to the inner surface of the cabinet. The guide plate one and the guide plate two are staggered, so that the air duct forms an S-shaped flow channel.

[0006] The internal circulation constant temperature and humidity module also includes an environmental treatment chamber, a conveying fan, and a conveying pipe. The environmental treatment chamber and the conveying fan are fixedly installed on the rear side of the cabinet. The upper end of the conveying pipe is fixedly connected to the cover plate, and its lower end is fixedly fitted into the inside of the cabinet. The input end of the conveying fan is connected to the inside of the cabinet through the cover plate and the conveying pipe, and its output end is connected to the input end of the environmental treatment chamber. The output end of the environmental treatment chamber is connected to the inside of the cabinet through the conveying pipe. By designing the internal circulation constant temperature and humidity module, an axial flow fan drives air to form a stable flow within the cabinet. The S-shaped air duct, formed by the staggered distribution of baffle plate one and baffle plate two, effectively extends the airflow path and enhances the heat exchange efficiency between the air and the inner wall, thereby significantly improving the temperature uniformity and environmental stability inside the cabinet. At the same time, the air is drawn into the environmental treatment chamber by the conveying fan, where the integrated constant temperature and humidity modules precisely regulate the air. The treated air then flows back into the cabinet, forming a highly efficient closed-loop control. This not only continuously maintains the constant temperature and humidity conditions required for flour storage and transportation, but also further optimizes energy utilization efficiency and environmental parameter consistency by enhancing the contact between the airflow and the inner wall.

[0007] In a preferred embodiment, the inside of the cover plate and the side surface facing the inside of the cabinet are provided with a collecting air duct; the collecting air duct is configured to concentrate the air inside the cabinet and introduce it into the inside of the cover plate, and is connected to the upper end of the conveying pipe.

[0008] As a preferred embodiment, the environmental treatment chamber integrates a constant temperature module and a constant humidity module for regulating the temperature and humidity of the air flowing through it.

[0009] In a preferred embodiment, the S-shaped flow channel is configured to force the airflow to increase the contact area and time with the inner wall surface as it flows through the air channel.

[0010] In a preferred embodiment, a support foot is fixedly connected to the outer surface of the inner liner, and the support foot is fixedly connected to the bottom side of the cabinet to raise the inner liner.

[0011] In a preferred embodiment, the number of axial flow fans is six, which are evenly distributed on the bottom side of the cabinet.

[0012] In a preferred embodiment, the inner liner is equipped with a modular storage and transportation module. The modular storage and transportation module includes a grid-shaped partition fixedly connected to the inside of the inner liner, and transfer boxes placed on the partition. By setting up the modular storage and transportation module and utilizing the grid-shaped partition inside the inner liner, a regular and flexible unit space is constructed, which facilitates the orderly placement and classified management of transfer boxes, greatly improving the organization and space utilization of storage and transportation operations. The RFID tag at the bottom of each transfer box works in conjunction with the RFID reader on the lower side of the inner liner to automatically identify and record the box position and storage and transportation status, realizing accurate tracking and real-time inventory management of flour inventory.

[0013] In a preferred embodiment, the upper end of the transfer box is provided with a box lid, the lower end of which is provided with an RFID tag, and the lower side of the inner liner is provided with an RFID reader that cooperates with the RFID tag.

[0014] After adopting the above technical solution, the beneficial effects of this utility model are:

[0015] 1. By designing an internal circulation constant temperature and humidity module, an axial flow fan drives air to form a stable flow inside the cabinet. Combined with an S-shaped air duct composed of staggered distribution of guide plates one and two, the airflow path is effectively extended and the heat exchange efficiency between the air and the inner wall is enhanced, thereby significantly improving the temperature uniformity and environmental stability inside the cabinet. At the same time, the air is drawn into the environmental treatment chamber by a conveying fan, where the integrated constant temperature and humidity module precisely controls the air. The treated air then flows back into the cabinet, forming a highly efficient closed-loop control. This not only continuously maintains the constant temperature and humidity conditions required for flour storage and transportation, but also further optimizes energy utilization efficiency and environmental parameter consistency by enhancing the contact between the airflow and the inner wall.

[0016] 2. By setting up modular storage and transportation modules and using grid-like partitions inside the inner liner, a regular and flexible unit space is constructed, which facilitates the orderly placement and classified management of transfer boxes, greatly improving the organization of storage and transportation operations and space utilization. The RFID tag at the bottom of each transfer box works in conjunction with the RFID reader on the lower side of the inner liner to automatically identify and record the box position and storage and transportation status, realizing accurate tracking and real-time inventory management of flour inventory.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figures 1-6 As the first embodiment of this utility model:

[0031] A flour storage and transportation integrated constant temperature and humidity cabinet includes: a cabinet body 1, the interior of the cabinet body 1 is filled with a heat insulation layer 11 made of polyurethane foam, a cover plate 2 is hinged to the upper end of the cabinet body 1, an inner liner 3 is fixedly connected to the interior of the cabinet body 1, and an internal circulation constant temperature and humidity module 4 is also provided inside the cabinet body 1 to maintain a stable internal environment.

[0032] The internal circulation constant temperature and humidity module 4 includes several sets of axial flow fans 41 set inside the bottom side of the cabinet 1, an air duct 42 formed between the inner liner 3 and the cabinet 1, a first guide plate 43 fixedly connected to the outer surface of the inner liner 3, and a second guide plate 44 fixedly connected to the inner surface of the cabinet 1. The first guide plate 43 and the second guide plate 44 are staggered, so that the air duct 42 forms an S-shaped flow channel.

[0033] The internal circulation constant temperature and humidity module 4 also includes an environmental treatment chamber 45, a conveying fan 46, and a conveying pipe 47. The environmental treatment chamber 45 and the conveying fan 46 are fixedly installed on the rear side of the cabinet 1. The upper end of the conveying pipe 47 is fixedly connected to the cover plate 2, and its lower end is fixedly fitted inside the cabinet 1. The input end of the conveying fan 46 is connected to the inside of the cabinet 1 through the cover plate 2 and the conveying pipe 47, and its output end is connected to the input end of the environmental treatment chamber 45. The output end of the environmental treatment chamber 45 is connected to the inside of the cabinet 1 through the conveying pipe 47. By designing the internal circulation constant temperature and humidity module 4, the axial flow fan 41 drives the air to circulate within the cabinet. The airflow is stable, and the S-shaped flow channel formed by the staggered distribution of guide plates 43 and 44 effectively extends the airflow path and enhances the heat exchange efficiency between the air and the inner wall of the liner 3, thereby significantly improving the temperature uniformity and environmental stability inside the cabinet. At the same time, the air is drawn into the environmental treatment chamber 45 by the conveying fan 46, where the air is precisely regulated by the integrated constant temperature and humidity module. The treated air is then returned to the cabinet, forming a highly efficient closed-loop control. This not only continuously maintains the constant temperature and humidity conditions required for flour storage and transportation, but also further optimizes energy utilization efficiency and environmental parameter consistency by enhancing the contact between the airflow and the inner wall of the liner 3.

[0034] An air collection duct is provided on the inside of the cover plate 2 and on the side facing the inside of the cabinet 1; the air collection duct is configured to concentrate the air inside the cabinet 1 into the inside of the cover plate 2 and is connected to the upper end of the delivery pipe 47.

[0035] The environmental treatment chamber 45 integrates a constant temperature module and a constant humidity module, which are used to regulate the temperature and humidity of the air flowing through it.

[0036] The S-shaped flow channel is configured to force the airflow to increase the contact area and time with the inner liner 3 wall as it flows through the air duct 42.

[0037] The outer surface of the inner liner 3 is fixedly connected to a support foot 31, which is fixedly connected to the bottom side of the cabinet 1 to raise the inner liner 3.

[0038] There are six axial flow fans 41, which are evenly distributed on the bottom side of the inside of the cabinet 1.

[0039] Specifically, the internal circulation constant temperature and humidity module 4 drives the airflow inside the cabinet through the axial flow fan 41. The air meanders through the S-shaped air duct 42 formed by the inner liner 3 and the cabinet wall 1. The staggered arrangement of the first guide plate 43 and the second guide plate 44 effectively extends the airflow path and enhances the heat exchange between the air and the inner liner 3 wall. At the same time, the conveying fan 46 draws part of the air inside the cabinet through the collecting air duct and conveying pipe 47 in the cover plate 2 to the environmental treatment chamber 45. The constant temperature module and constant humidity module integrated in the environmental treatment chamber 45 can be implemented using heating and humidification modules known in the art. For example, the constant temperature module may include heating and humidification modules. Heating elements (such as PTC heaters) and cooling elements (such as semiconductor cooling chips) control the heating or cooling state through temperature sensor feedback to achieve precise regulation of air temperature. The constant humidity module may include an ultrasonic humidifier and a dehumidification device (such as condensation dehumidification or rotary dehumidification), which controls the humidification or dehumidification operation through humidity sensor feedback to maintain the stability of air humidity inside the cabinet. This will not be elaborated further here. After the temperature and humidity are precisely regulated by the constant temperature module and the constant humidity module, they are returned to the cabinet through the conveying pipe 47 to form a closed-loop control, thereby continuously and stably maintaining the constant temperature and humidity environment required for flour storage and transportation.

The modular storage and transportation module 5 includes a grid-shaped partition 51 fixedly connected inside the inner liner 3, and a transfer box 52 placed on the partition 51. By setting up the modular storage and transportation module 5 and using the grid-shaped partition 51 inside the inner liner 3, a regular and flexible unit space is constructed, which facilitates the orderly placement and classified management of the transfer box 52, greatly improving the organization and space utilization of storage and transportation operations. The RFID tag 54 at the bottom of each transfer box 52 works in conjunction with the RFID reader 55 on the lower side of the inner liner 3 to automatically identify and record the box position and storage and transportation status, so as to realize accurate tracking and real-time inventory management of flour inventory.

[0042] The upper end of the transfer box 52 is provided with a box cover 53, and the lower end is provided with an RFID tag 54. The lower side of the inner liner 3 is provided with an RFID reader 55 that works with the RFID tag 54.

[0043] Based on the above embodiments, the modular storage and transportation module 5 further constructs a regular unit space by setting a grid-like partition 51 inside the inner liner 3, which facilitates the flexible placement and orderly management of the transfer boxes 52. The RFID tag 54 at the bottom of each transfer box 52 works in conjunction with the RFID reader 55 on the bottom side of the inner liner 3 to automatically identify and record the box position and storage and transportation information, realizing accurate tracking and inventory management of flour. The design of the box lid 53 further ensures the hygiene and safety of flour during storage and transportation, improving the overall practicality and management efficiency of the module.
