Abstract
The utility model relates to a compression cylinder configured at an adsorption tower. The compression cylinder comprises a cylinder fixed at the upper part of an adsorption tower, wherein a piston sheathed on an intermediate guide rod is mounted in the cylinder, at least two dowel bars are connected on the piston, the other end of each dowel bar penetrates through the adsorption tower and is connected with an internal piston plate in the adsorption tower, and a gas sampling port of the adsorption tower is connected with the cylinder through at least one connecting gas pipe; the cylinder is fixed on a flange cover plate at the upper part of the adsorption tower through a bolt, at least two dowel bars penetrate through a transmission sealing sleeve arranged at the flange cover plate, and a position-limiting switch for alarm is sheathed on one of the dowel bars; and the gas sampling port is arranged on the flange cover plate, and the gas sampling port is connected with the cylinder after connecting with the connecting gas pipe, a one-way valve and a pressure gauge in series. The compression cylinder has the characteristics of simple and reasonable structure, practicality, convenience and reliability, and can perform close tracking on the settling process of a molecular sieve and keep the compression state at any time so as to prolong the service life of the molecular sieve, improve the adsorption quality and the like.
Description
Technical field
The utility model relates to the cylinder of using on a kind of adsorption tower that compresses, belong to air separation machinery technical field.
Background technique
In recent years, because transformation absorption (PSA) technological develop rapidly, the application of making nitrogen by pressure swing adsorption system oxygen also more and more widely.But because in the pressure-swing absorption process, equipment is after long-term work, the molecular sieve in the adsorption tower normally compresses down; Because the cyclically-varying of tower internal pressure, local subsidence possibly take place in molecular sieve, thereby influences the proper functioning of equipment; Reduce the life time of molecular sieve, especially influence absorption quality.Therefore existing technology exists variable-pressure adsorption equipment and compresses difficulty, can not follow the tracks of the decline degree of molecular sieve, and it is very big to take the interior space of adsorption tower, has both wasted source of the gas in the use, can not protect molecular sieve not by technological deficiencies such as efflorescence again.
Summary of the invention
The purpose of the utility model is to overcome the deficiency that existing technology exists, and can carry out tight tracking to molecular sieve sinking process and provide a kind of, keeps impaction state at any time, to improve the cylinder that compresses that is disposed at adsorption tower of molecular sieve life time.
The following technological scheme of passing through of the utility model is accomplished; It comprises that one is fixed in the cylinder on adsorption tower top; One piston that is nested with in intermediate guide bar is installed in the cylinder; Be connected with at least two dowel bars on the piston, and the other end of dowel bar passes adsorption tower, links to each other with inner carrier plate in the adsorption tower, the air hatch of adsorption tower connects tracheae through at least one and is connected to described cylinder.
Described cylinder is through on the flange plate that is bolted to adsorption tower top, and at least two dowel bars pass the flange plate place and are provided with the transmission seal cover, and is equipped with the limit switch that is used to report to the police therein on the dowel bar.
Described flange plate is provided with air hatch, wherein after connecting tracheae, one-way valve and pressure gauge serial connection, is connected in described cylinder.
The utility model belongs to a kind of improvement to existing technology, and it has simple and reasonable for structure, and is practical and convenient reliable, can carry out tight tracking to molecular sieve sinking process, keeps impaction state at any time, to improve the molecular sieve life time, improves characteristics such as absorption quality.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
To combine accompanying drawing that the utility model is done detailed introduction below: shown in Figure 1 is the described cylinder that compresses that is disposed at adsorption tower; It comprises that one is fixed in the cylinder 1 on adsorption tower top; One piston 3 that is nested with in intermediate guide bar 2 is installed in the cylinder 1; Be connected with at least two dowel bars 4 on the piston 3, and the other end of dowel bar 4 passes adsorption tower, links to each other with inner carrier plate in the adsorption tower, the air hatch 5 of adsorption tower connects tracheae 6 through at least one and is connected to described cylinder 1.
Described flange plate 8 is provided with air hatch 5, wherein after connecting tracheae 6, one-way valve 11 and pressure gauge 12 serial connections, is connected in described cylinder 1.
The described cylinder upper of the utility model has a guide rod 2, is used to estimate lowering position; A limit switch is used for reporting to the police; One connects tracheae 6, is used to provide source of the gas; There is a piston 1 that is used to push down dowel bar 4 cylinder 1 inboard; Dowel bar 4 is unlikely to along with play about the variation of adsorption tower internal pressure, and a circle internal thread is arranged at piston 1 top, is used for fixing guide rod 2; Along with molecular sieve bed descends and moves down; Dowel bar 4 is used to withstand adsorption tower inner carrier plate, prevents that molecular sieve is loosening, thereby causes efflorescence; Air hatch 5 is from giving vent to anger in the adsorption tower through one-way valve 11, pressure gauge 12 to cylinder 1; Can check inner cylinder pressure from pressure gauge 12; 9 in transmission seal cover guarantees that gas can not overflowed in the adsorption tower in drive link 4; Fixing bolt 7 is fixed together with flange plate 8 compressing cylinder 1, thereby plays pressuring action.
Compare other tradition compress technology as: spring compression, porcelain ball compress etc., and cylinder compresses technology, stressedly evenly do not descend with molecule again and change pressure, and it is little to take in the tower space, and can observe the process of molecular sieve decline from the outside.Can give the alarm by position limit switch is installed at the top again, tell the user in advance, prepare to add molecular sieve.
