[0020] like Figure 1 As shown, the vacuum conveying control system for moisture-absorbing materials in this embodiment includes an air compressor 1, a refrigerated dryer 2, a desiccant dryer 3, an air storage tank 8, a first hopper 12, a first air filter 15, a vacuum feeder 20, a second hopper 21, and a Roots blower 26. The air compressor 1, the refrigerated dryer 2, the desiccant dryer 3, and the air storage tank 8 are connected in sequence. At this time, the air compressor 1 can supply compressed air. After the compressed air passes through the refrigerated dryer 2 to remove moisture, it enters the desiccant dryer 3 to remove moisture and oil from the compressed air, so as to ensure the cleanliness and dryness of the compressed air. The air storage tank 8 is used to store compressed air.

[0021] In this embodiment, a first pressure transmitter 7 is installed on the top of the air storage tank 8. The first pressure transmitter 7 can collect and monitor the pressure value of the air storage tank 8. The outlet of the air storage tank 8 is connected to the first end of the three-way pipe through a first angle seat valve 9 and a first manual ball valve 10. The first angle seat valve 9 can automatically switch on and off to control the air intake, and the first manual ball valve 10 is used to control the compressed air replenishment.

[0022] Furthermore, a mixer 11 is connected to the top of the first silo 12. The mixer 11 contains powder materials and can mix the powder materials. The first silo 12 and the first air filter 15 are connected in parallel and then connected to the second end of the three-way pipe. A first pneumatic butterfly valve 13 is connected between the outlet of the first silo 12 and the three-way pipe. The first pneumatic butterfly valve 13 can control the discharge of the powder materials temporarily stored in the first silo 12. A second manual ball valve 14 is connected between the first air filter 15 and the three-way pipe. The first air filter 15 can filter impurities in the air, and the second manual ball valve 14 is used to control natural air replenishment. The third end of the three-way pipe is connected to the vacuum feeder 20 through the second pressure transmitter 16 and the second pneumatic butterfly valve 17.

[0023] At this time, after filtering the powder material, the vacuum feeder 20 exhausts the air. The outlet of the vacuum feeder 20 is connected to a second hopper 21, which is used to temporarily store the material. The exhaust port of the vacuum feeder 20 is connected to a Roots blower 26, which is used to provide negative pressure and suck up the material. Preferably, a third pneumatic butterfly valve 18 for controlling the inflow and outflow of material is provided at the outlet of the vacuum feeder 20.

[0024] Specifically, a fourth pneumatic butterfly valve 19, a vacuum gauge 24, and a third pressure transmitter 25 are sequentially installed on the pipeline between the vacuum feeder 20 and the Roots blower 26. The fourth pneumatic butterfly valve 19 is used to control exhaust, the vacuum gauge 24 can monitor the exhaust pressure, and the third pressure transmitter 25 collects the monitored pressure value. Simultaneously, a fifth pneumatic butterfly valve 22 for controlling exhaust is connected to the pipeline between the fourth pneumatic butterfly valve 19 and the vacuum gauge 24. The fifth pneumatic butterfly valve 22 is connected to a second air filter 23, which can filter impurities in the air.

[0025] In this embodiment, a third manual ball valve 4, a pressure reducing valve 5, and a second angle seat valve 6 are sequentially installed on the pipeline between the desiccant 3 and the air storage tank 8. The third manual ball valve 4 serves as a switch for easy inspection and maintenance, the pressure reducing valve 5 can reduce the compressed air pressure, and the second angle seat valve 6 can automatically open and close to control the air intake.

[0026] In this embodiment, at least one of the first manual ball valve 10 or the second manual ball valve 14 is in the closed state to switch between natural air replenishment and compressed air replenishment. Specifically, when the ambient humidity is less than 80%, the first manual ball valve 10 is closed and the second manual ball valve 14 is opened, i.e., natural air replenishment is used; when the ambient humidity is greater than 80%, the second manual ball valve 14 is closed and the first manual ball valve 10 is opened, i.e., dry compressed air replenishment is used.

[0027] In this embodiment, the vacuum conveying control system for moisture-absorbing materials operates as follows: When the ambient humidity is less than 80%, the first manual ball valve 10 is closed and the second manual ball valve 14 is opened, allowing for natural air replenishment; when the ambient humidity is greater than 80%, the second manual ball valve 14 is closed and the first manual ball valve 10 is opened. Then, the air compressor 1, refrigerated dryer 2, desiccant 3, third manual ball valve 4, second angle seat valve 6, and first angle seat valve 9 are activated, using dry and clean compressed air for replenishment. The system can only automatically operate to absorb material when the pressure transmitter 7 on the air tank 8 exceeds a threshold value, preferably 1.2 kg pressure. Then, the automatic... Press the run button, and the system will start automatically, automatically opening the second angle seat valve 6, the first angle seat valve 9, and the Roots blower 26. When the third pressure transmitter 25 exceeds a certain pressure, the fifth pneumatic butterfly valve 22 will automatically open to protect the equipment. During material conveying, the first pneumatic butterfly valve 13, the second pneumatic butterfly valve 17, and the fourth pneumatic butterfly valve 19 will automatically open and automatically close after a certain period of time. Then, the third pneumatic butterfly valve 18 will be opened for a certain period of time, and then the first pneumatic butterfly valve 13, the second pneumatic butterfly valve 17, and the fourth pneumatic butterfly valve 19 will continue to be opened, and the cycle will continue.

[0028] In the vacuum conveying control system for moisture-absorbing materials of this utility model, when the ambient humidity is greater than 80%, the powder moisture-absorbing materials are mixed and then sucked to the next process by a negative pressure vacuum feeder. During the material suction process, clean and dry compressed air can be used to replenish the air.

[0029] This utility model's vacuum conveying control system for moisture-absorbing materials incorporates an air compressor, a refrigerated dryer, a desiccant, and an air storage tank. When the air humidity is low, natural air can be used for replenishment; when the air humidity is high, dry and clean compressed air can be used for replenishment. This ensures that the conveying of powder materials is not affected by environmental factors and avoids blockage of material pipelines.

[0030] The embodiments described above are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Various modifications and improvements made to the technical solutions of the present utility model by those skilled in the art without departing from the spirit of the present utility model should fall within the protection scope defined by the claims of the present utility model.
