Description

Technical Field

[0001] The utility model relates to the technical field of nitrogen generators, in particular to an energy-saving device for a nitrogen generator. Background Art

[0002] The nitrogen generator is a nitrogen production equipment designed and manufactured according to the pressure swing adsorption technology. The nitrogen generator uses high-quality imported carbon molecular sieve (CMS) as the adsorbent and adopts the pressure swing adsorption principle (PSA) at room temperature to separate air and produce high-purity nitrogen. Usually two adsorption towers are connected in parallel. The imported pneumatic valve is controlled by the imported PLC to automatically operate, and pressurized adsorption and decompression regeneration are performed alternately to complete the separation of nitrogen and oxygen to obtain the required high-purity nitrogen.

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

The left side of the nitrogen generator body 2 is connected to a first air inlet pipe 6.

[0023] Among them, an air compressor 7 is fixed on the upper surface of the base plate 1, the input end of the air compressor 7 is connected to a first connecting pipe, the output end of the air compressor 7 is connected to a second connecting pipe, the other end of the second connecting pipe is connected to the left side of the first air intake pipe 6, the air compressor 7 passes air into the first air intake pipe 6, the outside of the first air intake pipe 6 is connected to two filters 8, and they are symmetrically distributed on the left and right sides of the central axis of the first air intake pipe 6. The filters 8 filter impurities in the air to avoid interference with nitrogen production.

[0024] See also Figure 2-3 In order to avoid the waste of electricity caused by the continuous operation of the nitrogen generator, the energy-saving mechanism 4 in this embodiment includes a support plate 401 fixed to the outside of the first outlet pipe 3, a mounting plate 402 is fixed on the upper surface of the support plate 401, a connecting pipe 403 is provided on the inner side of the first outlet pipe 3 to facilitate the passage of the prepared nitrogen, a sealing gasket is fixed on the outer side of the connecting pipe 403 to prevent nitrogen leakage, a cylinder 404 is fixed on the upper surface of the mounting plate 402, and the output shaft of the cylinder 404 passes through and extends to the mounting plate 40 2, and a connecting rod 405 is fixed thereto. The cylinder 404 drives the connecting rod 405 to move. The bottom end of the connecting rod 405 passes through and extends to the inside of the first air outlet pipe 3, and is fixed with a clamping block 406. The connecting rod 405 drives the clamping block 406 to move. A rubber pad 407 is fixed to the inner side of the clamping block 406. The clamping block 406 drives the rubber pad 407 to move, thereby clamping the connecting pipe 403 to prevent the connecting pipe 403 from falling off. The outside of the first air outlet pipe 3 is connected to the first solenoid valve 408.

[0025] In this example, there are four support plates 401, and two of them form a group. They are symmetrically distributed up and down with the central axis of the first air outlet pipe 3 to improve the stability of the connecting pipe 403 when clamping. A mounting groove is provided on the inner side of the clamping block 406, and a contact sensor 409 is fixed on the inner side of the mounting groove. After the rubber pad 407 contacts the connecting pipe 403, the contact sensor 409 senses the contact signal, the cylinder 404 stops moving, and at the same time the first solenoid valve 408 opens, and the nitrogen generator body 2 starts to run. When the cylinder 404 drives the clamping block 406 to move upward and leave the connecting pipe 403, the signal of the contact sensor 409 is interrupted, the first solenoid valve 408 is closed, and the nitrogen generator body 2 stops working.

[0026] See also Figure 4In order to make full use of the compressed air, the circulation mechanism 5 in this embodiment includes a booster pump 501 fixed to the left side of the nitrogen generator body 2.

The output end of the booster pump 501 is connected to a second air outlet pipe 503.

The other end of the second air outlet pipe 503 is connected to the outside of the first air inlet pipe 6.

[0027] In this example, a gas detector 504 is fixed on the outside of the second outlet pipe 503, and the gas detector 504 detects the cost in the gas. The outside of the second outlet pipe 503 is connected to the third outlet pipe 505, and the outside of the second outlet pipe 503 is connected to the second solenoid valve 506. When the nitrogen content in the gas is higher than the limit value, the second solenoid valve 506 opens, and the gas flows from the second outlet pipe 503 into the first inlet pipe 6 for circulating nitrogen production. The outside of the third outlet pipe 505 is connected to the third solenoid valve 507. When the nitrogen content in the gas is lower than the limit value, the third solenoid valve 507 opens, and the gas flows out from the third outlet pipe 505.

[0028] The working principle of the above embodiment is:

[0029] (1) First, place the connecting pipe 403 into the first air outlet pipe 3, open the cylinder 404, and the cylinder 404 drives the connecting rod 405 to move, the connecting rod 405 drives the clamping block 406 to move, and the clamping block 406 drives the rubber pad 407 to move, thereby clamping the connecting pipe 403 to prevent the connecting pipe 403 from falling off. After the rubber pad 407 contacts the connecting pipe 403, the contact sensor 409 senses the contact signal, the cylinder 404 stops moving, and at the same time the first solenoid valve 408 opens, the nitrogen generator body 2 starts to run, the air compressor 7 passes air into the first air inlet pipe 6, the filter 8 filters the impurities in the air, and then the gas enters the nitrogen generator body 2 to make nitrogen.

[0030] (2) During the nitrogen production process of the nitrogen generator body 2, nitrogen is discharged from the first outlet pipe 3 and discharged from the connecting pipe 403 for storage or use. The gas after the nitrogen is separated is discharged from the exhaust pipe. The booster pump 501 draws the gas discharged from the exhaust pipe into the interior through the second inlet pipe 502 and pressurizes it, and then discharges it from the second outlet pipe 503. At this time, the gas detector 504 detects the cost in the gas. When the nitrogen content in the gas is higher than the limit value, the second solenoid valve 506 opens, and the gas is passed from the second outlet pipe 503 to the first inlet pipe 6 for circulating nitrogen production. When the nitrogen content in the gas is lower than the limit value, the third solenoid valve 507 opens, and the gas is discharged from the third outlet pipe 505.
