Description

Technical Field

[0001] This utility model relates to the field of differential pressure precooling storage technology, specifically to a differential pressure precooling storage air outlet device. Background Technology

[0002] A differential pressure precooling system is a refrigeration system that uses the principle of differential pressure for cooling. It is mainly used for the rapid cooling and preservation of agricultural products such as fruits and vegetables. Its working principle is to create a certain pressure difference on both sides of the packaging container through the suction action of the differential pressure fan, so that cold air is forced through the ventilation holes on the packaging container to pass through the product surface, thereby achieving a rapid and uniform cooling effect. The air outlet device is an important component of the differential pressure precooling system. It can drive the air flow through suction to create a pressure difference, thereby cooling and preserving the product.

[0003] While traditional air outlet devices can drive airflow to create a pressure difference, they still have some shortcomings. For example, their filtration effect is poor, so dust and impurities from the outside air are blown into the storage room during airflow, which can affect products such as fruits and vegetables. In addition, their air outlet structure is relatively fixed, so it is difficult to adjust the air outlet direction according to actual needs when dealing with fruits and vegetables of different shapes and stacking methods, thus making it difficult to ensure that the cold air is evenly distributed to every corner. Therefore, to address the above problems, a pressure differential precooling storage air outlet device is proposed. Utility Model Content

[0004] The purpose of this invention is to provide an air outlet device for a differential pressure precooling warehouse, which has a better filtration effect and therefore will not blow dust and impurities from the outside air into the warehouse when the air is vented, thereby avoiding the impact of dust and impurities on fruits and vegetables. In addition, its air outlet structure is more flexible, so the air outlet direction can be adjusted according to actual needs when dealing with fruits and vegetables of different shapes and stacking methods, thereby ensuring that the cold air can be evenly distributed to every corner, thus solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A differential pressure precooling chamber air outlet device includes a chamber body. Axial flow fans are symmetrically and fixedly connected to the center of each of the two side walls of the chamber body. Air guide hoses are provided at the center of each of the two side walls of the inner cavity of the chamber body. One end of the air guide hose passes through the side wall of the chamber body and is connected to the output end of the axial flow fans. The other end of the air guide hose is fixedly connected to a matching air guide sleeve. A filter assembly is provided on the side of the air guide sleeve away from the air guide hose. Directional adjustment assemblies are symmetrically provided on the two side walls of the inner cavity of the chamber body.

[0007] Preferably, the filter assembly includes a filter screen that matches the specifications of the air guide sleeve. The upper and lower ends of the filter screen are symmetrically hinged with mounting brackets, and mounting blocks are fixedly connected to the mounting brackets. The upper and lower ends of the air guide sleeve are symmetrically provided with mounting slots.

[0008] Preferably, the mounting block and the mounting slot are positioned correspondingly and matched in specifications. The mounting support plate has a mounting bolt passing through it on the side away from the mounting block. The upper and lower ends of the air guide sleeve have symmetrical mounting screw holes on the side away from the mounting slot that correspond to the positions of the mounting bolts and match in specifications.

[0009] Preferably, the directional adjustment assembly includes an electric push rod that passes through and is fixedly connected to the side wall of the tank body, and a fixed support plate that is fixedly connected to the inner side wall of the tank body. The upper and lower ends of the air guide sleeve near the air guide hose are longitudinally symmetrical and fixedly connected to connecting support plates.

[0010] Preferably, transmission support plates are symmetrically hinged to the two connecting support plates, and the ends of the two transmission support plates away from the connecting support plates are respectively fixedly connected to the output end of the electric push rod and the fixed support plate.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] In this invention, the storage chamber can accommodate fruits and vegetables, while the axial flow fan creates a pressure difference by drawing in air. A flexible air duct allows the air drawn in by the axial flow fan to be discharged into the storage chamber, thus cooling and preserving the fruits and vegetables. A filter assembly, installed on the air duct sleeve, provides excellent filtration for the air duct, preventing dust and impurities from being blown into the storage chamber and thus avoiding damage to the fruits and vegetables. The entire design is easy to disassemble, simplifying cleaning and maintenance. A directional control component allows adjustment of the airflow direction through the air duct sleeve, enabling adjustments to the airflow direction based on the shape and stacking method of the fruits and vegetables, ensuring even distribution of cool air to every corner and preventing cooling dead zones.

[0023] Please see Figure 1-6 This utility model provides a technical solution:

[0024] A differential pressure precooling chamber air outlet device includes a chamber body 1. Axial flow fans 2 are symmetrically and fixedly connected to the center of the two side walls of the chamber body 1. Air guide hoses 3 are provided at the center of the two side walls of the inner cavity of the chamber body 1. One end of the air guide hose 3 passes through the side wall of the chamber body 1 and is connected to the output end of the axial flow fans 2. The other end of the air guide hose 3 is fixedly connected to an air guide sleeve 4 of matching specifications. A filter assembly 5 is provided on the side of the air guide sleeve 4 away from the air guide hose 3. Directional adjustment assemblies 6 are symmetrically provided on the two side walls of the inner cavity of the chamber body 1.

[0025] The filter assembly 5 includes a filter screen 501 that matches the specifications of the air guide sleeve 4. The filter screen 501 has mounting brackets 502 symmetrically hinged to its upper and lower ends. Mounting blocks 503 are fixedly connected to the mounting brackets 502. The air guide sleeve 4 has symmetrically opened mounting slots 504 at its upper and lower ends. The mounting blocks 503 and mounting slots 504 are positioned and matched in specifications. A mounting bolt 505 passes through the side of the mounting bracket 502 away from the mounting block 503. The air guide sleeve 4 has symmetrically opened mounting screw holes 506 on the side of its upper and lower ends away from the mounting slots 504, corresponding to the positions and specifications of the mounting bolts 505. The filter assembly 5, when installed on the air guide sleeve 4, provides good filtration for the air guide hose 3, thus preventing dust and impurities from the outside air from being blown into the storage body 1 when the air guide hose 3 is discharging air, thereby avoiding the impact of dust and impurities on fruits, vegetables, and other products. Furthermore, its overall design is easy to disassemble, making cleaning and maintenance more convenient and reducing the difficulty of later maintenance. The directional component 6 includes an electric push rod 601 that penetrates through and is fixedly connected to the side wall of the storage body 1, and a fixed support plate 602 that is fixedly connected to the inner side wall of the storage body 1. The upper and lower ends of the air guide sleeve 4 near the air guide hose 3 are longitudinally symmetrical and fixedly connected to connecting support plates 603. The two connecting support plates 603 are symmetrically hinged to transmission support plates 604. The ends of the two transmission support plates 604 away from the connecting support plates 603 are respectively fixedly connected to the output end of the electric push rod 601 and the fixed support plate 602. The directional component 6 can adjust the air outlet direction of the air guide hose 3 through the air guide sleeve 4. Therefore, when facing fruits and vegetables of different shapes and stacking methods, the air outlet direction can be adjusted according to actual needs, thereby ensuring that the cold air can be evenly distributed to every corner and avoiding the formation of cooling dead zones.

[0026] Workflow: First, power on all electrical appliances and connect them to external controllers. Storage unit 1 can accommodate fruits and vegetables. Axial flow fan 2 drives airflow through suction to create a pressure difference. Air duct 3 discharges the air drawn in by axial flow fan 2 into storage unit 1, thus cooling and preserving the fruits and vegetables. The filter screen 501 in filter assembly 5, installed on air guide sleeve 4, provides excellent filtration for air duct 3, blocking dust and impurities from the airflow. Therefore, dust and impurities from outside air will not be blown into storage unit 1 when air is discharged from air duct 3, preventing damage to fruits and vegetables. Furthermore, the assembly is easy to disassemble, making cleaning and maintenance convenient and reducing maintenance difficulty. During installation, first place the filter screen 501 on one side of air guide sleeve 4 and attach it to it. Then, rotate the two mounting plates 502 to attach to the upper and lower ends of the air duct, and simultaneously insert the mounting clips 503. Position and engage the mounting bolt 505 in the mounting slot 504. At this point, the hole in the mounting bolt 505 corresponds to the mounting screw hole 506. Finally, screw the mounting bolt 505 into the mounting screw hole 506. Disassembly is similar. The directional adjustment component 6 can adjust the airflow direction of the air guide hose 3 via the air guide sleeve 4. Therefore, when dealing with fruits and vegetables of different shapes and stacking methods, the airflow direction can be adjusted according to actual needs, ensuring that cold air is evenly distributed to every corner and avoiding cooling dead zones. When adjusting the airflow direction... Taking the upward adjustment of the wind direction as an example, the electric push rod 601 is activated to extend it. The extension of the electric push rod 601 will drive the transmission support plate 604 on it to move to the right in sync. This transmission support plate 604 will then drive the lower end of the air guide sleeve 4 to move to the right through the adjacent connecting support plate 603. At the same time, the upper end of the air guide sleeve 4 will move to the left through the transmission support plate 604 connected to the fixed support plate 602 and the upper connecting support plate 603. At this time, the air guide sleeve 4 will drive the air guide hose 3 to tilt upward. The same principle applies when adjusting the downward wind direction.
