Description

Technical Field

[0001] This utility model relates to the field of piston oxygen compressor technology, specifically a highly stable oxygen pressure supply device. Background Technology

[0002] A piston oxygen compressor, also known as a reciprocating oxygen compressor, is a device that uses the reciprocating motion of a piston to compress oxygen. The piston oxygen compressor uses the reciprocating motion of the piston within a cylinder to compress and expand the gas inside the cylinder, thereby increasing the pressure of low-pressure oxygen to the required high pressure.

[0003] Currently, piston oxygen compressors use a single piston to compress air, which cannot guarantee a high and stable oxygen pressure supply. Moreover, the pressure at the oxygen outlet varies greatly during oxygen supply, resulting in high airflow pulsation, which causes equipment vibration and is detrimental to stable operation. Utility Model Content

[0004] The purpose of this invention is to provide a highly stable oxygen pressure supply device, which has the advantages of ensuring a highly stable oxygen pressure supply, filtering air and reducing airflow pulsation, thus enabling stable operation of the equipment and solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-stability oxygen pressure supply device, comprising a drive box, cylinders, and a filter buffer box. The drive box contains symmetrically distributed rotating shafts, each with a rotating disk at its end. An eccentric shaft is mounted at the front end of the rotating disk, and a rotating sleeve is mounted on the eccentric shaft. A connecting rod is mounted on the rotating sleeve. Two cylinders are symmetrically mounted on the upper end of the drive box, communicating with it. Each cylinder contains a piston, with a rotating component at its lower end. The end of the connecting rod is connected to the rotating component. The filter buffer box is mounted on the upper end of the two cylinders. An installation port is provided on the side of the filter buffer box, through which a filter layer is installed. A first perforated plate and a second perforated plate are installed above the filter layer inside the filter buffer box, with the second perforated plate positioned above the first perforated plate.

[0006] When using the high-stability oxygen pressure supply device of this utility model, the two rotating disks can be rotated by the operation of the drive equipment. With the cooperation of the eccentric shaft and the connecting rod, the piston can reciprocate in the cylinder. External air enters the cylinder through the intake pipe. The air is compressed and discharged from the outlet pipe into the filter buffer box. The air can be filtered through the filter layer to remove impurities. After filtration, the air passes through the first and second perforated plates again, which can change the airflow from a standing wave to a traveling wave, thereby reducing the unevenness of the airflow pressure. Finally, the air is discharged from the exhaust pipe, thus performing high-stability oxygen pressure supply.

[0007] Preferably, the drive box has an equipment box on its side, the rotating shaft extends into the equipment box and a pulley is installed therein, and a transmission belt is provided between the pulleys.

[0008] Preferably, a drive device is installed inside the equipment housing, and the main shaft of the drive device is connected to the axis of the pulley located on the left side. The drive device rotates the pulley on the left side, which in turn rotates the pulley on the right side under the action of the transmission belt, thereby causing both rotating discs to rotate.

[0009] Preferably, an intake pipe is installed on the side end of the cylinder, and a one-way intake valve is provided on the intake pipe. Outside air can enter the cylinder through the intake pipe.

[0010] Preferably, an air outlet pipe is provided between the filter buffer box and the cylinder, and a one-way air outlet valve is provided on the air outlet pipe. Compressed air can be discharged into the filter buffer box from the air outlet pipe.

[0011] Preferably, the upper end of the filter buffer box is provided with an exhaust pipe, which is connected to the filter buffer box.

[0012] Preferably, a mounting plate is installed at the front end of the filter layer, and the mounting plate has mounting holes arranged in an array. The side end of the filter buffer box has threaded holes corresponding to the mounting holes, and bolts are threaded into the mounting holes and threaded holes. The mounting holes and threaded holes, together with the bolts, allow the mounting plate to be installed and fixed, thereby installing the filter layer.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: In the oxygen pressure supply operation, the air is compressed and supplied by two cylinders working simultaneously, which can ensure the oxygen pressure. After the compressed air enters the filter buffer box, it can be filtered and buffered. This not only removes impurities from the air, but also changes the airflow in the pipeline from a standing wave to a traveling wave through the orifice plate, reducing the unevenness of the airflow pressure, thereby reducing airflow pulsation, achieving the purpose of vibration reduction, making the equipment operate stably, and ensuring a highly stable oxygen pressure supply operation.
