Abstract
The utility model relates to a molecular sieve compressing structure for a pressure swing adsorption nitrogen machine, which comprises an upper sealing head of an absorbing canister body, a distributor, a molecular sieve, material supplementing openings and a molecular sieve compressing device, wherein the molecular sieve compressing device is composed of air cylinders and compressing heads arranged at the end part of cylinder piston rods, flame plates used for fixing the air cylinders are arranged at the opening end of the material supplementing openings, the material supplementing openings are formed uniformly in the housing surface of the upper sealing head of the absorbing canister body, the air cylinders are fixed on the flame of the material supplementing openings, and the compressing heads at the end part of the piston rods are in contact with the molecular sieve below the distributor. The structure provided by the utility model has the advantages that as the compressing heads of the compressing device compress the molecular sieve, pulverization caused by the friction of the molecular sieve is decreased, the service life of the molecular sieve is prolonged, the purity and flow of the nitrogen is improved, and when the molecular sieve is short of material, and the interval is larger than the regulated stroke of the compressing device, the alarm rings reminder the field operation worker to supplement materials.
Description
Technical field
The utility model relates to a kind of transformation adsorbed gas isolation technics, especially relates to a kind of molecular sieve compressing structure of varying-voltage adsorption nitrogen machine.
Background technology
Transformation adsorbed gas isolation technics has that energy consumption is low, easy to operate, the good plurality of advantages of environmental benefit, adopts the Double-Tower Structure gas separation equipment of this technology to obtain using widely.At present, during nitrogen making machine work, gases at high pressure enter from the bottom of absorber, and at this moment, the top pressure of absorber is low, discontinuity equalization up and down, make the molecular sieve rolling and produce relative motion, the frictional force that produce this moment very easily causes the efflorescence of carbon molecular sieve, molecular sieve after the efflorescence loses the ability of adsorb oxygen, finally influences purity and the flow of nitrogen making machine.Be to reduce the negative effect that the efflorescence of carbon molecular sieve brings, the inventor carries out improvement design in conjunction with on-the-spot characteristics at the structure of varying-voltage adsorption nitrogen machine, has avoided the loss that causes because of the molecular sieve efflorescence, thereby has reduced the production cost of enterprise.
Summary of the invention
The purpose of this utility model is to provide a kind of efflorescence that effectively prevents molecular sieve at the prior art weak point, can also in time point out the molecular sieve compressing structure of the varying-voltage adsorption nitrogen machine of feed supplement.
The purpose of this utility model is to realize by following measure: a kind of molecular sieve compressing structure of varying-voltage adsorption nitrogen machine, it comprises absorber cylindrical shell upper cover, distributor, molecular sieve, it is characterized in that, also has material-feeding port, molecular sieve compressing device, described molecular sieve compressing device is by cylinder, the pressure head that is fixed on the cylinder piston boom end is formed, material-feeding port mouth end is provided with the fixedly ring flange of cylinder, described material-feeding port is distributed on absorber cylindrical shell upper cover shell face, cylinder is fixed on the material-feeding port ring flange, and the pressure head that is installed in the piston rod end touches mutually with the molecular sieve that is positioned at the distributor below.
Described cylinder piston rod extends certain distance outward travel switch is installed outward, and travel switch links to each other with alarm.
Compared with prior art, adopted the molecular sieve compressing structure of the varying-voltage adsorption nitrogen machine that the utility model proposes, have following advantage: the pressure head by hold down gag compresses molecular sieve, reduce the efflorescence that the friction of molecular sieve causes, prolonged the service life of molecular sieve, improved purity and the flow of nitrogen, when molecular sieve lacks material, when the gap surpasses the hold down gag prescribed stroke, alarm equipment alarm, prompting site operation personnel feed supplement in time.
Description of drawings:
Fig. 1 is an example structure schematic diagram that the utility model proposes.
Fig. 2 is Fig. 1 embodiment A-A profile.
Fig. 3 is the hold down gag structural representation.
The specific embodiment:
Below in conjunction with accompanying drawing the specific embodiment is elaborated: Fig. 1 ~ Fig. 3 shows an embodiment of the present utility model.Among the figure, a kind of molecular sieve compressing structure of varying-voltage adsorption nitrogen machine, it comprises: absorber cylindrical shell upper cover 1, distributor 6, molecular sieve 7, material-feeding port 2, molecular sieve compressing device, described molecular sieve compressing device is made up of cylinder 3, the pressure head 5 that is fixed on cylinder piston rod 4 ends, 2 mouthfuls of ends of material-feeding port are provided with the fixedly ring flange of cylinder 3, described material-feeding port 2 is distributed on absorber cylindrical shell upper cover 1 shell face, cylinder 3 is fixed on material-feeding port 2 ring flanges, and the pressure head 5 that is installed in the piston rod end touches mutually with the molecular sieve 7 that is positioned at the distributor below.
The utility model is further taked following measure: described cylinder 3 piston rods extend certain distance outward travel switch are installed outward, and travel switch links to each other with alarm.
The utility model is work like this: when nitrogen making machine was worked, gases at high pressure entered from the bottom of absorber, and this moment, the absorber top was normal pressure, discontinuity equalization, the easy tumbling motion of carbon molecular sieve.For rolling and the motion that prevents molecular sieve, cylinder provides a downward pressure all the time, this pressure can be adjusted up and down according to specification of equipment, by compressing the molecular sieve in the absorber, reduce moving up and down of molecular sieve, and then the efflorescence that causes of the friction that reduces molecular sieve, improve the operating efficiency of nitrogen making machine, prolong the service life of molecular sieve.Molecular sieve when absorber the inside reduces to a certain degree, when surpassing the stroke of setting, can send the timely feed supplement of sound and light alarm signal prompt site operation personnel.
The embodiment that provides does not above constitute restriction of the present utility model, and those skilled in the art make various distortion within the scope of the appended claims or revise all in protection domain in this area.
