Abstract

The utility model discloses a molecular sieve closing device, including the container, the container top is equipped with the internal thread joint of being connected with the blind flange, and the blind flange still is equipped with the gasket through a plurality of bolts, nut and flange joint between blind flange and the flange, is equipped with spring location pipe, lower spring location pipe, pressure spring, sieve, coir pad and molecular sieve in the container cavity in proper order. The utility model has the advantages that: this device has practiced thrift the manufacturing degree of difficulty of equipment, has reduced manufacturing cost moreover, has reduced spare part processing requirement, has also reduced the height simultaneously, obtains better use in the on-vehicle nitrogen system of system after highly reducing, and the instrument when changing the packing is converted into ordinary box spanner by big torsion air wrench, does not have the injury to equipment screw and flange, also can not cause the not hard up phenomenon of packing through permanent use, simple structure.

Description

Molecular sieve pressing device

Technical Field

The utility model relates to a clarification plant technical field specifically is a molecular sieve closing device.

Background

Compressing device among the prior art generally is the cylinder, coir mat and clamp plate structure, but the cylinder is bulky, it requires highly to spare part processing, manufacturing cost is big, control system is numerous and diverse, coir mat and clamp plate are in the use throughout the year, function such as automatic compensation or elasticity reservation are not enough, lead to the molecular sieve under high-pressure draught's impact, the phenomenon that becomes flexible appears, and the pulverization appears, seriously influence the output quality of nitrogen gas, and this compact structure must use big torsion pneumatic tool when the maintenance, on-vehicle equipment is because high restriction, can't use pneumatic spanner, the phenomenon of damage bolt and flange still can appear, cause equipment failure.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a molecular sieve closing device to solve the problem that proposes among the above-mentioned background art.

In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a molecular sieve closing device, includes the container, the container top is equipped with the internal thread joint of being connected with the blind flange, the blind flange passes through a plurality of bolts, nut and flange joint, the blind flange with still be equipped with the gasket between the flange, be close to in the container cavity the upper end of flange is equipped with spring location pipe and lower spring location pipe in proper order, it is provided with pressure spring with spring location pipe outside periphery down to go up the spring location pipe, the pressure spring lower extreme is equipped with the sieve, the sieve is kept away from pressure spring's lower extreme is equipped with the palm pad, the palm pad is kept away from the lower extreme of sieve is equipped with the molecular sieve.

Preferably, the container and the flange are of an integrally formed structure.

Preferably, the compression spring is sleeved on the upper spring positioning pipe and the lower spring positioning pipe.

Preferably, the flange cover is connected with the flange through at least eight bolts and nuts.

Preferably, the upper end of the sieve plate is connected with the lower spring positioning pipe and the compression spring.

Advantageous effects

This device has practiced thrift the manufacturing degree of difficulty of equipment, has reduced manufacturing cost moreover, has reduced spare part processing requirement, has also reduced the height simultaneously, obtains better use in the on-vehicle nitrogen system of system after highly reducing, and the instrument when changing the packing is converted into ordinary box spanner by big torsion air wrench, does not have the injury to equipment screw and flange, also can not cause the not hard up phenomenon of packing through permanent use, simple structure.

Detailed Description

The following are specific embodiments of the present invention and are further described with reference to the drawings, but the present invention is not limited to these embodiments.

Examples

As shown in fig. 1-2, a molecular sieve pressing device, comprises a container 13, an internal thread joint 1 connected with a flange cover 3 is arranged at the top end of the container 13, the flange cover 3 is connected with a flange 5 through a plurality of bolts 2 and nuts 6, a gasket 4 is further arranged between the flange cover 3 and the flange 5, an upper spring positioning pipe 8 and a lower spring positioning pipe 9 are sequentially arranged at the upper end, close to the flange 5, in a cavity of the container 13, a pressing spring 7 is arranged around the outer sides of the upper spring positioning pipe 8 and the lower spring positioning pipe 9, a sieve plate 10 is arranged at the lower end of the pressing spring 7, a palm cushion 12 is arranged at the lower end, far away from the pressing spring 7, of the sieve plate 10, and a molecular sieve 11 is arranged.

Preferably, the container 13 and the flange 5 are of an integral structure.

Preferably, the compression spring 7 is sleeved on the upper spring positioning tube 8 and the lower spring positioning tube 9.

Preferably, the flange cover 3 is connected to the flange 5 by at least eight bolts 2 and nuts 6.

Preferably, the upper end of the sieve plate 10 is connected with the lower spring positioning pipe 9 and the compression spring 7.

The air flow scours the adsorber, and when the filler descends, the spring can quickly compensate the space after descending, so that the molecular sieve is prevented from generating a phenomenon of piston type up-and-down motion, and the surface pulverization caused by friction generated when the molecular sieve is loosened is effectively avoided, and the failure is caused.

Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments described in the foregoing embodiments, or equivalents may be substituted for elements thereof. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the content of the present invention within the protection scope of the present invention.
