[0042] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0043] This utility model embodiment provides an airflow material pulverizing equipment room, such as... Figure 1 As shown, the airflow material crushing equipment room includes an equipment room 9, a return air duct 91, and an air compressor 1, an airflow crusher 4, a cyclone collector 5, a dust collector 6, and an induced draft fan 7, etc., installed in the equipment room 9.

[0044] Equipment room 9 is a sealed chamber with an openable sealed door for installing an airflow pulverizing system.

[0045] An airflow mill 4 is installed inside the equipment chamber 9 and is used for airflow milling of materials. The airflow mill 4 is vertically arranged, and its lower part is equipped with a matching air inlet 41 and a feed inlet. The feed inlet is connected to the feeding unit 42 and is used to continuously supply the material to be milled into the airflow mill 4. The air inlet 41 is circumferentially arranged at the lower part of the airflow mill 4 and includes multiple air inlets and nozzles, which are used to provide uniformly dispersed dry compressed airflow into the airflow mill 4; the compressed airflow entering the air inlet 41 interacts with the material entering the feed inlet to achieve material milling.

[0046] Air compressor 1 is installed in equipment room 9 and is used to provide compressed air. The outlet end of air compressor 1 is connected to the air inlet 41 of air jet mill 4 to provide dry compressed air to air jet mill 4.

[0047] Cyclone collector 5 is used for separating powder and airflow, and collecting the powder. The air inlet of cyclone collector 5 is connected to the airflow outlet at the top of airflow mill 4, and collects and processes the airflow and materials discharged from airflow mill 4.

[0048] The dust collector 6 is installed after the cyclone collector 5. The inlet end of the dust collector 6 is connected to the airflow outlet of the cyclone collector 5. It is used to remove impurities in the compressed airflow to ensure that the discharged compressed airflow is clean and meets the emission and reuse standards.

[0049] The induced draft fan 7 is installed after the dust collector 6. The inlet end of the induced draft fan 7 is connected to the airflow outlet of the dust collector 6, and the outlet end of the induced draft fan 7 is connected to the exhaust pipe 71 outside the equipment room 9 through a pipeline to ensure that the used and treated airflow is smoothly discharged or reused.

[0050] One end of the return air duct 91 is connected to the exhaust duct 71, and the other end is connected to the equipment room 9. It can draw the dry gas exhausted outside back into the equipment room 9 to regulate the air humidity in the equipment room 9.

[0051] In summary, the airflow material crushing equipment room is equipped with a return air duct 91, which draws the dry airflow used for filtering and exhausting after airflow crushing in the airflow crushing system back into the equipment room 9. This is used to regulate and control the air humidity in the equipment room 9, avoid the problem of excessive air humidity in the equipment room 9, reduce the need for air dehumidifiers or reduce the frequency of use of air dehumidifiers, and can effectively save energy consumption and operating costs.

[0052] Preferably, a first valve 711 is installed on the exhaust pipe 71, and a second valve 911 is installed on the return air pipe 91. The return air pipe 91 is connected to the pipe at the end of the first valve 711 near the induced draft fan 7. Preferably, the first valve 711 and the second valve 911 are linked to adjust and control the exhaust of dry air or its return to the equipment room 9.

[0053] Several air humidity detectors 8 are installed in the equipment room 9 to detect the air humidity in the equipment room 9.

[0054] Preferably, a control module is provided, which associates the air humidity detector 9 with the first valve 711 on the exhaust pipe 71 and the second valve 911 on the return air pipe 91. Based on the air humidity detection results within the equipment room 9, the module can automatically control the discharge of the dry airflow from the air pulverizing system or its return to the equipment room 9. Specifically, when the air humidity detector 9 detects that the air humidity is greater than a set threshold, it closes the first valve 711 and opens the second valve 911, returning the dry gas to the equipment room 9 to regulate the air humidity; when the air humidity detector 9 detects that the air humidity is less than the set threshold, it closes the second valve 911 and opens the first valve 711, discharging the dry gas.

[0055] Preferably, the return air duct 91 is connected to the area where the air compressor 1 is installed in the equipment room 9, which can quickly adjust the air humidity around the air compressor 1 and quickly reduce the humidity of the compressed air generated by the compressor 1.

[0056] The system also includes an air storage tank 2 and a refrigerated dryer 3, which are sequentially positioned between the air compressor 1 and the air jet mill 4. The inlet end of the air storage tank 2 is connected to the outlet end of the air compressor 1, and the outlet end of the air storage tank 2 is connected to the inlet end of the refrigerated dryer 3 and the air inlet 41 of the air jet mill 4. The outlet end of the refrigerated dryer 3 is also connected to the air inlet 41 of the air jet mill 4. The air storage tank 2 stores compressed air, providing a stable compressed airflow for the subsequent air jet milling system. The compressed air in the air storage tank 2 can be cooled and dried by the refrigerated dryer 3 before being sent to the air inlet 41 of the air jet mill 4, or it can be directly sent to the air inlet 41 of the air jet mill 4.

[0057] Furthermore, the outlet end of the gas storage tank 2 is connected to the air inlet 41 via a first pipe 21, and a third valve 211 is provided on the first pipe 21. The inlet end of the refrigerated dryer 3 is provided with an air inlet pipe connected to the first pipe 21 near the end of the third valve 211 closest to the gas storage tank 2, and a fourth valve 31 is provided on the air inlet pipe. The outlet end of the refrigerated dryer 3 is provided with an air outlet pipe connected to the first pipe 21 near the end of the third valve 211 closest to the air jet mill 4, and a fifth valve 32 is provided on the air outlet pipe. That is, the refrigerated dryer 3 and the third valve 211 are connected in parallel. The compressed gas in the gas storage tank 2 can be directly discharged to the air jet mill 4, or it can be cooled and dried by the refrigerated dryer 3 before being discharged to the air jet mill.

[0058] Furthermore, an airflow humidity detector 212 is also provided on the first pipeline 21. Preferably, the airflow humidity detector 212 is located before the connection between the air inlet pipe of the refrigerated dryer 3 and the first pipeline 21, near the outlet end of the air tank 2. The airflow humidity detector 212 is associated with the third valve 211, the fourth valve 31, and the fifth valve 32. The airflow humidity detector 212 is used to detect the humidity of the compressed airflow discharged from the air tank 2. Specifically, in use, if the airflow humidity detector 212 detects that the humidity of the compressed airflow is lower than the preset airflow humidity value, the fourth valve 31 and the fifth valve 32 are closed, and the third valve 211 is opened, so that the compressed airflow in the air tank 2 is directly discharged to the airflow pulverizer 4 for airflow pulverization; if the airflow humidity detector 212 detects that the humidity of the compressed airflow is higher than the preset airflow humidity value, the third valve 211 is closed, the fourth valve 31 and the fifth valve 32 are opened, and the refrigerated dryer 3 is run to dry the compressed airflow in the air tank 2 before discharging it to the airflow pulverizer 4 for airflow pulverization.

[0059] The airflow outlet of the air jet mill 4 is connected to the air inlet of the cyclone collector 5 via a pipeline. Preferably, the cyclone collector 5 is positioned higher than the air jet mill 4, so that the airflow outlet of the air jet mill 4 and the air inlet of the cyclone collector 5 are connected via an upwardly inclined straight pipe 43. The upwardly inclined straight pipe 43 can perform horizontal sorting, allowing particles that are too large or too heavy to fall back into the air jet mill 4 for further crushing, which can make the material crushing more thorough and ensure that the discharged powder is more uniform.
