Description

Technical Field

[0002] Molecular sieve oxygen generator is an oxygen production equipment that uses the physical adsorption and desorption technology of molecular sieve to produce oxygen. Its core lies in the molecular sieve filled in the oxygen generator. The molecular sieve in the adsorption tower inside the oxygen generator can adsorb nitrogen in the air when pressurized, and the remaining unabsorbed oxygen is collected and purified to become high-purity oxygen. Molecular sieve is a spherical or strip-shaped particle, the main component of which is inorganic silicate. It will be impacted by the rising raw air and the reverse analytical gas in the adsorption tower in turn, and it is easy to creep and thus pulverize. The pulverized molecular sieve is discharged with the product gas and analytical gas, and the output and purity of the entire oxygen production equipment will decrease as a result.

[0003] Therefore, a compression device is required inside the molecular sieve adsorption tower to ensure that the molecular sieves can fit tightly together. At the same time, when the molecular sieve fails due to pulverization, other molecular sieves need to be added to ensure the output and purity of the entire oxygen production equipment.

[0029] The connecting rod is arranged on the central axis of the head 1 and the stuffing accommodating cavity. A plurality of pressure rods 6 and push rods 7 are symmetrically arranged inside the head 1 relative to the connecting rod. The plurality of pressure rods 6 are evenly distributed along the circumferential direction of the connecting rod, so as to ensure that the top plate 9 is subjected to uniform force.

[0030] One end of the pressure rod 6 is movably connected to the third connecting rod 13, and the other end of the pressure rod 6 is movably connected to the head 1; a waist hole is set in the middle of the pressure rod 6, one end of the push rod 7 is slidably connected to the waist hole, and the other end of the push rod 7 is fixedly connected to the top plate 9; the bottom end of the third connecting rod 13 is fixedly connected to the top plate 9.

[0035] Specifically, the number of the pressure rods 6 and the push rods 7 is 2. On the premise of ensuring that the top plate 9 is evenly stressed, three or four pressure rods 6 may be evenly distributed along the circumferential direction of the connecting rod.

[0036] Specifically, the top plate 9 is a porous plate. The porous plate is provided to allow oxygen to pass smoothly.

[0037] Installation process of this utility model:

[0038] First, install the sealing plate 3 on the flange above the packing accommodating chamber, and fix the cylinder 5 on the sealing plate 3 through the center hole of the sealing plate 3; then fix the spring 4 to the cylinder 5, and connect the molecular sieve top plate 2 below the spring 4. Connect the cylinder 5 to the first connecting rod 11, the first connecting rod 11 is threadedly connected to the second connecting rod 12, the second connecting rod 12 is welded to the third connecting rod 13, and a gap 8 is left at the connection between the second connecting rod 12 and the third connecting rod 13.

[0039] The working process of this utility model:

[0040] The utility model drives the connecting rod to move up and down through the cylinder 5, so as to realize the up and down movement of the push rod 7. When the push rod 7 moves downward, it drives the top plate 9 to press the molecular sieve in the adsorption tower; when the push rod 7 moves upward, the top plate 9 presses the space inside the filler accommodating cavity upward, and the molecular sieve falls into the adsorption tower below through the third connecting rod 13 to complete the replenishment of the molecular sieve.

[0041] Before installation, first fill the cavity of the filler receiving cavity with molecular sieve.

[0042] Compressing process: when the cylinder 5 drives the connecting rod to move downward, the push rod 7 moves downward, driving the top plate 9 to move downward, thus completing the compacting work of the molecular sieve.

[0043] Refilling process: When the cylinder 5 drives the connecting rod to move upward, it drives the top plate 9 to move upward, and the top plate 9 relaxes the molecular sieve in the adsorption tower. The empty space of the filler accommodating cavity between the connecting rod and the molecular sieve top plate 2 is squeezed, causing the molecular sieve therein to flow from the gap 8 of the third connecting rod 13 into the molecular sieve below, thereby completing the replenishment of the molecular sieve.

[0044] It can be understood that the above specific description of the utility model is only used to illustrate the utility model and is not limited to the technical solution described in the embodiments of the utility model.
