[0029] See also Figure 1-Figure 5The utility model provides an upper frame space division structure, comprising an outer frame 1, a first partition layer 2 and a second partition layer 3. The first partition layer 2 and the second partition layer 3 are arranged in the outer frame 1 at intervals to divide the inner cavity of the outer frame 1 into an upper material cavity 4, a test cavity 5 and a lower material cavity 6. The first partition layer 2 is located between the upper material cavity 4 and the test cavity 5, and the second partition layer 3 is located between the test cavity 5 and the lower material cavity 6. The upper material cavity 4 is provided with at least one first dry air inlet. After the upper material cavity 4 is filled with dry air, a high-pressure area is formed. The first partition layer 2 is provided with a first through hole that can conduct the upper material cavity 4 and the test cavity 5, and the second partition layer 3 is provided with a second through hole that can conduct the test cavity 5 and the lower material cavity 6. The inner cavity of the outer frame 1 is divided into three relatively independent areas, namely, a loading cavity 4, a testing cavity 5 and a lowering cavity 6. A large number of first dry air inlets are arranged on the inner wall surface of the loading cavity 4. After the dry air is filled in, the pressure in the loading cavity 4 rises to form a high-pressure area. By utilizing the pressure difference among the loading cavity 4, the testing cavity 5 and the lowering cavity 6, the dry air can be accelerated to flow toward the testing cavity 5 and the lowering cavity 6 in a directional manner and finally discharged out of the equipment, thereby reducing the drying time of the equipment and ensuring the drying effect of the equipment.

[0030] Furthermore, the first partition layer 2 is provided with a first sealing door 21 for realizing the opening and closing of the first through hole and a first power mechanism 22 for controlling the opening and closing of the first sealing door 21. When the first sealing door 21 closes the first through hole, the dry air filled into the loading chamber 4 can quickly fill the entire loading chamber 4, so that it forms a high pressure. At this time, the pressure difference between the loading chamber 4 and the test chamber 5 is large. Then, the first sealing door 21 is driven by the first power mechanism 22 to open the first through hole, and the dry air in the loading chamber 4 can quickly enter the test chamber 5 through the first through hole until the test chamber 5 is filled, so that the test chamber 5 also forms a high pressure.

[0031] Furthermore, the second partition layer 3 is provided with a second sealing door 31 for realizing the opening and closing of the second through hole and a second power mechanism 32 for controlling the opening and closing of the second sealing door 31. When the second sealing door 31 closes the second through hole, the dry air entering the test chamber 5 can quickly fill the entire test chamber 5, so that it also forms a high-pressure chamber, and then the second sealing door 31 is driven by the second power mechanism 32 to open the second through hole. By utilizing the pressure difference between the test chamber 5 and the feeding chamber 6, the dry air in the test chamber 5 can quickly enter the feeding chamber 6 through the second through hole, thereby achieving the effect of drying the equipment and improving the drying efficiency.

[0032] Further, the first power mechanism 22 includes a first cylinder or a first electric screw or a first electric pulley. Preferably, the first power mechanism 22 is a first cylinder, and the output end of the first cylinder is connected to the first sealing door 21, so that the first cylinder can drive the first sealing door 21 to move.

[0033] Further, the second power mechanism 32 includes a second cylinder or a second electric screw or a second electric pulley. Preferably, the second power mechanism 32 is a second cylinder, and the output end of the second cylinder is connected to the second sealing door 31, so that the second cylinder can drive the second sealing door 31 to move.

[0034] Specifically, the first sealing door 21 can be a whole door, and the first through hole can be opened and closed by driving the first sealing door 21 to move through a first cylinder; the first sealing door 21 can also be composed of multiple first sealing plates, and each first sealing plate is driven separately by multiple first cylinders. The shape of each first sealing plate can be the same or different, and the driving direction of each first cylinder can be the same or different.

[0035] Specifically, the second sealing door 31 can be a whole door, and the second through hole can be opened and closed by driving the second sealing door 31 through a second cylinder; Figure 6 The second sealing door 31 may also be composed of a plurality of second sealing plates, each of which is driven by a plurality of second cylinders. The shape of each second sealing plate may be the same or different, and the driving direction of each second cylinder may be the same or different.

[0036] Furthermore, at least one second dry air inlet is provided in the test chamber 5, and the number of the second dry air inlets is less than the number of the first dry air inlets. Most of the dry air in the test chamber 5 flows in from the dry air in the loading chamber 4. When the dew point of the dry air rises after passing through the loading chamber 4, a small amount of dry air is filled into the test chamber 5 through the second dry air inlet, so that the dry air flowing out of the loading chamber 4 can be compensated to a certain extent in the test chamber 5, so that the dew point drops again and the dryness is guaranteed.

[0037] Optionally, a small number of third dry air inlets are provided on the feeding chamber 6 , and the number of the third dry air inlets is smaller than the number of the second dry air inlets, which is conducive to forming a pressure difference between the test chamber 5 and the feeding chamber 6 .

[0038] It should be noted that the first dry air inlet, the second dry air inlet and the third dry air inlet are all micropores capable of blowing dry air, and are respectively distributed on the inner walls around the loading chamber 4, the test chamber 5 and the unloading chamber 6. The first dry air inlet, the second dry air inlet and the third dry air inlet are all connected to the air pipe to blow dry air into the equipment.

[0039] Furthermore, an exhaust port capable of exhausting gas to the outside is provided on the lower material chamber 6. Compared with the upper material chamber 4 and the test chamber 5, the lower material chamber 6 is a low-pressure area, but in fact, part of the dry gas is also filled into the lower material chamber 6, so that the pressure in the lower material chamber 6 is greater than the atmospheric pressure outside the sorting machine, and there is a pressure difference between the lower material chamber 6 and the external environment, and the gas in the lower material chamber 6 can be discharged to the external environment from the exhaust port.

[0040] Furthermore, a first low-temperature structure is provided in the feeding chamber 4 for reducing the internal temperature of the feeding chamber 4. The first low-temperature structure is arranged in the feeding chamber 4, and the feeding chamber 4 is a high-pressure area, and the air in other areas is not easy to enter the feeding chamber 4, which can ensure the dryness in the feeding chamber 4 and ensure that no frost will occur.

[0041] Furthermore, a second low-temperature structure is provided in the test chamber 5 for reducing the temperature inside the test chamber 5. After the dry air enters the test chamber 5, the pressure in the test chamber 5 also rises, so that the pressure in the test chamber 5 is greater than the pressure in the feeding chamber 6. The air in the feeding chamber 6 is not easy to enter the test chamber 5, which can ensure the dryness in the test chamber 5. The second low-temperature structure is arranged in the test chamber 5 to ensure that it will not frost. The normal temperature structure is provided in the feeding chamber 6, which can effectively improve the drying speed of the equipment.

[0042] Furthermore, there is a first gap between the first partition layer 2 and the outer frame 1, and there is a second gap between the second partition layer 3 and the outer frame 1, and the dry air in the loading cavity 4 can enter the test cavity 5 from the first gap, and the dry air in the test cavity 5 can enter the unloading cavity 6 from the second gap. It should be noted that both the first gap and the second gap are tiny gaps that can only allow a small amount of dry gas to pass through. In this case, most of the dry air between the cavities still flows through the first through hole and the second through hole, and only a small amount of dry air flows through the first gap and the second gap.

[0043] The above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit the protection scope of the utility model.
