Description

Technical Field

[0001] This utility model relates to the field of grain depot storage equipment, specifically a sealed air supply box for grain depot air conditioning. Background Technology

[0002] Grain depot air conditioning is a professional temperature control and dehumidification device specifically designed for grain storage scenarios. Its core function is to create a stable and suitable storage environment for grains such as wheat, rice, corn, and soybeans by precisely regulating the temperature and humidity inside the grain depot, thereby inhibiting grain mold, insect infestation, and aging, reducing storage losses, and ensuring grain quality and safety.

[0003] The sealed air supply box for grain depot air conditioning is the core component of the grain depot air conditioning system, which enables air supply, ensures airtightness and air quality. Its core function is to efficiently and evenly deliver temperature and humidity regulated air to the inside of the grain depot or grain pile, while isolating external dust, pests and temperature and humidity interference to ensure a stable grain storage environment.

[0004] Maintaining suitable temperature and humidity within the grain depot is crucial for the safe storage of grain. Currently, grain depots generally use air conditioning systems to regulate the environment. However, existing air supply devices have some problems in actual use. For example, the air supply box doors are mostly manually opened, which is inconvenient to operate and makes it difficult to ensure good sealing, leading to cold air leakage and affecting the cooling effect and energy utilization of the air conditioning system. Furthermore, the air supply angle and air volume adjustment of traditional air supply devices rely on manual adjustment, which is not flexible enough and cannot meet the needs of different grain depot layouts and grain stacking conditions.

A rotating rod 4 is mounted at one end of the connecting block 3, and a transmission assembly 6 for rotating the rotating rod 4 is mounted at one end of the rotating rod 4. The transmission assembly 6 includes a full gear 60, a rack 61, and a positioning block 62. The full gear 60 is fitted onto the outer wall of the rotating rod 4, and a rack 61 is mounted on the outer wall of the full gear 60. A positioning block 62 is mounted at one end of the rack 61, and an electric push rod 63 is mounted at one end of the positioning block 62. An air outlet 9 is provided on the inner wall of the door frame body 1. Through the transmission assembly 6 and the insulated air duct 8, the existing air supply devices address issues related to door opening methods and sealing. To address issues related to the stability of the connection with the ductwork and the flexibility of air supply adjustment, this system aims to improve the working efficiency and energy-saving performance of the grain depot's air conditioning system, ensuring suitable temperature and humidity within the grain depot. Through the installation of the sealing strip 10, the air-sealable box door is electrically controlled. Connected to the door body 2 via the transmission component 6, the electric push rod 63 receives external air conditioning control signals, causing the rotating rod 4 to rotate and drive the door body 2 to smoothly open or close along the guide rail. Furthermore, a corrosion-resistant sealing strip is installed at the contact point between the door body 2 and the door frame body 1. This sealing strip uses a special weather-resistant rubber material with good elasticity and corrosion resistance, effectively preventing air leakage and ensuring the airtightness of the box.

[0031] For details regarding the above embodiments, please refer to [link / reference]. Figures 3-5The outer wall of the air outlet 9 is provided with a sealing strip 10, and the sealing strip 10 is attached to the outer wall of the door 2. The sealing strip 10 is made of special weather-resistant rubber material, which has good elasticity and corrosion resistance, and can effectively prevent air leakage and ensure the airtightness of the air inside the box.

[0032] For details regarding the above embodiments, please refer to [link / reference]. Figures 1-4 One end of the door frame body 1 is provided with an insulated air duct 8, and the door frame body 1 and the insulated air duct 8 are fixedly connected. The door frame body 1 is connected to the insulated air duct 8 and is fixed with a TC connector. The TC connector has the characteristics of firm connection and convenient installation, and can be tightly fitted into the connection part of the air supply box and the insulated air duct 8.

[0033] For details regarding the above embodiments, please refer to [link / reference]. Figures 1-5 The gear 60 and the rack 61 mesh with each other, and a fixing block 64 is provided at the end of the rack 61 away from the gear 60. The outer wall of the transmission component 6 is covered with a protective shell 5, which protects the transmission component 6 and effectively improves the service life of the transmission component 6.

[0034] For details regarding the above embodiments, please refer to [link / reference]. Figures 2-5 A protrusion is provided at one end of the rack 61 near the fixing block 64, and a groove is provided at one end of the fixing block 64 near the rack 61.

[0037] Second embodiment: Please see Figures 1-4The difference between Embodiment 2 and Embodiment 1 is that, while retaining Embodiment 1, a limiting groove 7 is added to the outer wall of the door frame body 1, so that the connecting block 3 and the rotating rod 4 are engaged with the limiting groove 7, thereby limiting the position of the door body 2, improving the stability of the door body 2 during the operation of the air outlet 9, reducing the shaking of the door body 2, and effectively improving the service life of the door body 2.

[0038] In practical operation, this utility model is as follows: When the device is needed in the grain warehouse, the air supply sealed box is installed on the air supply duct of the grain warehouse air conditioning system. First, the installation position of the air supply sealed box is determined according to the layout of the grain warehouse and the design requirements of the air conditioning system. Then, the insulated air duct 8 is firmly connected to one end of the air supply box through the TC connector and sealed with glue. Next, the transmission component 6 at one end of the door 2 is installed to ensure that the door 2 can open and close smoothly. At the same time, the air outlet 9 is installed in a suitable position inside the air supply box, and the air volume regulating valve and the control motor are connected to ensure that it can communicate normally with the external control system. During the daily operation of the grain depot, environmental data is monitored in real time by temperature and humidity sensors installed at different locations within the depot. When the temperature and humidity of a certain area exceed the set range, the external control system, according to a preset program, first uses the sensor to cause the electric push rod 63 to retract, which in turn moves the rack 61, thereby driving the full gear 60 to rotate, causing the rotating rod 4 to rotate the door 2. Then, it sends control signals to the air outlet 9 motor and the air volume regulating valve inside the door frame 1. The motor drives the electric ball nozzle to adjust its angle, directing the cold air towards the area where the temperature and humidity need to be regulated. At the same time, the air volume regulating valve adjusts its opening according to actual needs, controlling the amount of air supplied, thereby achieving precise regulation of the temperature and humidity inside the grain depot.
