[0040] Specifically, the chassis 1 is ignited and started to maintain the parking state, the additional power supply and additional gas source switches are turned on, and the power take-off is in the engaged state; connecting pipe 62: the pressure-resistant pipe, mobile pressure regulating device, and special nitrogen releaser are connected to the required nitrogen output port, wherein these pipeline accessories are connected with quick-plug connectors, and the operation is efficient and convenient; after the pipeline connection is completed and the releaser is at the disposal point, the PLC intelligent control mechanism 4 turns on the nitrogen output mode by controlling the touch screen 42, and at this time, the chassis 1 power take-off drive shaft drives the air compressor 2 to start running, and at this time, the air is compressed and enters the membrane nitrogen making device to separate oxygen, water and other substances, and the output pressure is about 1Mpa The high-purity nitrogen on the right; at this time, the corresponding outlet pressure is adjusted, and the nitrogen will reach the hazardous chemical disposal site through the pipeline; the outlet pressure is manually adjusted through the switching mechanism 63 in the pipeline mechanism 6, and the position between the guide component 64 and the pressure dividing component 65 in the switching mechanism 63 is manually driven by the control component 67, so that one of the notches in the high-pressure and low-pressure areas of the pressure dividing component 65 is connected to the guide mechanism, so that the gas pressure output from the external port 69 fixedly connected at the bottom end of the switching mechanism 63 is more manually set according to the needs, thereby improving the flexibility of the device during use and reducing the cumbersome phenomenon caused by switching the pressure in the pipeline;

[0041] The pressure dividing assembly 65 includes a fixed sleeve 651, an internal tube 652 is fixedly connected inside the fixed sleeve 651, a low-pressure notch 653 is provided at the top of the internal tube 652, and a high-pressure notch 654 is provided at the bottom of the internal tube 652; a throttling assembly 66 is provided at one end of the internal tube 652 close to the low-pressure notch 653, and the throttling assembly 66 is adapted to the low-pressure notch 653, and a branch pipe 656 is fixedly connected to the bottom of the internal tube 652;

[0042] Specifically, the fixed sleeve 651 in the pressure dividing component 65 is a cylindrical structure, and the built-in tube 652 fixedly connected in the fixed sleeve 651 is a cylindrical columnar structure. A symmetrical and inclined low-pressure slot 653 is opened at the top of the built-in tube, and a high-pressure slot 654 is opened in an array at the bottom of the built-in tube. The low-pressure slot 653 is adapted to the throttling component 66 at an inclined angle, so that when the gas in the low-pressure slot 653 passes through the throttling component 66, the throttling component 66 intermittently blocks the low-pressure slot 653, so that the gas is depressurized. When the gas enters the built-in tube 652 from the high-pressure slot 654, the high-pressure gas state is maintained because there is no intervention of the throttling component 66. The device has a simple structure and is flexible to use, and is worthy of wide promotion.

[0044] Specifically, the fixed ring 641 in the guide assembly 64 is fixed to the movable ring through the capsule ring 642, and the capsule ring 642 is rolled inward, so that the plane cross-sectional view is a U-shaped structure, and the air inlet hole 644 opened in the fixed ring 641 is connected with the guide hole 645 opened in the movable ring 643, so that when the movable ring 643 switches its position along the built-in tube 652, the capsule ring 642 can move and move synchronously, so that the gas in the capsule ring 642 is not affected by the movement of the movable ring 643, and the gas is guided, thereby improving the flexibility of gas guidance;

[0045] The throttling assembly 66 includes a connecting column 661, and the connecting column 661 is fixed on the fixing sleeve 651.

The throttling block 665 distributed in a triangular structure in the fixed disk 663 indirectly closes the low-pressure slot 653 during rotation, so that the throttling assembly 66 reduces the pressure of the gas penetrating the low-pressure slot 653, and the switching mechanism 63 is switched between high pressure and low pressure, thereby improving the flexibility of the device and avoiding the limitations caused by the use of a high-pressure single tube and a low-pressure single tube.

[0047] The control assembly 67 includes a lock sleeve 671, and the lock sleeve 671 is fixed on the inner wall of the switching mechanism 63.

[0048] Specifically, the locking sleeve 671 in the control component 67 has a symmetrical structure.

The connecting rod 677 located at the bottom end of the locking rod 673 and fixedly connected by the connecting arm 676 drives the movable ring 643 to move along the built-in tube 652, thereby realizing manual adjustment of the position of the movable ring 643, switching between high pressure and low pressure according to needs, and reducing the limitations of the device during use.

[0049] Working principle: Chassis 1 is ignited and kept in parking state, the additional power supply and additional gas source switches are turned on, and the power take-off is in the engaged state; connecting pipe 62: the required nitrogen output port is connected to the pressure-resistant pipe, mobile pressure regulating device, and special nitrogen releaser, where these pipe accessories are connected with quick-connect connectors, and the operation is efficient and convenient; after the pipe connection is completed and the releaser is at the disposal point, the PLC intelligent control mechanism 4 turns on the nitrogen output mode by controlling the touch screen 42. At this time, the power take-off transmission shaft of chassis 1 drives the air compressor 2 to start running. At this time, the air is compressed and enters the membrane nitrogen making device to separate oxygen, water and other substances. The output pressure is about 1Mpa The high-purity nitrogen on the right; at this time, the corresponding outlet pressure is adjusted, and the nitrogen will reach the hazardous chemical disposal site through the pipeline; the outlet pressure is manually adjusted through the switching mechanism 63 in the pipeline mechanism 6, and the position between the guide component 64 and the pressure dividing component 65 in the switching mechanism 63 is manually driven by the control component 67, so that one of the slots in the high-pressure and low-pressure areas of the pressure dividing component 65 is connected to the guide mechanism, so that the gas pressure output from the external port 69 fixedly connected at the bottom of the switching mechanism 63 can be manually set as needed, thereby improving the flexibility of the device during use and reducing the cumbersome phenomenon caused by switching the pressure in the pipeline.
