Description

High stability diaphragm type metal end cover for desicator

Technical Field

The utility model relates to a gas drying filter's spare part field specifically is a metal end cover for high stability diaphragm type desicator.

Background

Membrane dryers, which dry compressed air based on the characteristic of the permeable polymeric membrane material of water molecules that permeate and diffuse, and if gas partial pressures (different concentrations) exist at the two ends of the membrane, gas molecules will permeate the membrane and diffuse molecules from the direction of higher partial pressure to the direction of lower partial pressure, and such devices are widely used in various fields, for example: compressed natural gas, fire control, food and beverage, gas analysis and control, laser processing and the like, and the application environment is complicated and changeable, so that the membrane dryer has higher requirements on the structural stability.

The end cover is used as an important component of the membrane dryer, the stability of the end cover greatly influences the overall quality of the membrane dryer, most of the existing end covers for the membrane dryer are made of PVC materials, the strength and the sealing performance of threads are required to be enhanced, when the membrane dryer works in a vibration environment, the end cover is easy to trip, and air leakage is easy to occur in a high-temperature environment and a low-temperature environment.

SUMMERY OF THE UTILITY MODEL

To the above-mentioned condition, for overcoming current technical defect, the utility model provides an intensity is high, and the leakproofness is good, high low temperature resistant, resistant vibration, stable in structure, convenient to use, long service life's high stability metal end cover for membrane dryer.

The utility model adopts the following technical scheme: the utility model provides a pair of metal end cover for high stability diaphragm type desicator, includes diaphragm type stick, a protection sleeve section of thick bamboo, end cover and fixed bolster, a protection sleeve section of thick bamboo is hollow columnar structure, the diaphragm type stick is located in a protection sleeve section of thick bamboo, the diaphragm type stick both ends outside is equipped with the external screw thread, the end cover inboard is equipped with the internal thread, the end cover is equipped with two sets ofly, and is two sets of the end cover is located diaphragm type stick both ends through threaded connection, the fixed bolster is located on the end cover, be equipped with the fixed orifices on the fixed bolster.

Furthermore, the membrane type rod, the protective sleeve, the end cover and the fixed support are all made of aluminum alloy materials.

Furthermore, the circumference of the inner side wall of the end cover is provided with a groove, the groove is positioned above the inner thread of the end cover, and an O-shaped ring is arranged between the grooves.

Adopt above-mentioned structure the utility model discloses the beneficial effect who gains as follows: the utility model relates to a metal end cover for high stability diaphragm type desicator, its advantage lies in: be equipped with the protective sleeve for the whole life of equipment increases, and the fixed bolster makes overall stability better, prevents that the end cover from tripping, and the leakproofness has been strengthened in the existence of O type circle, chooses for use the metal material to improve holistic intensity, and wear-resisting high low temperature resistant is applicable to various extreme operational environment.

Drawings

The accompanying drawings are included to provide a further understanding of the invention, and are incorporated in and constitute a part of this specification, illustrate embodiments of the invention, and together with the description serve to explain the principles of the invention. In the drawings:

FIG. 1 is a schematic view of the overall structure of a parallel membrane dryer according to the present invention,

figure 2 is an exploded view of the overall structure of a parallel membrane dryer of the present invention,

fig. 3 is a cross-sectional view of an end cap of a parallel membrane dryer according to the present invention.

The device comprises a membrane type rod 1, a membrane type rod 2, a protective sleeve 3, an end cover 4, a fixing support 5, a fixing hole 6 and an O-shaped ring.

Detailed Description

The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, rather than all embodiments, and all other embodiments obtained by a person of ordinary skill in the art without creative work belong to the protection scope of the present invention based on the embodiments of the present invention.

It should be noted that the terms "front," "back," "left," "right," "upper" and "lower" used in the following description refer to directions in the drawings, and the terms "inner" and "outer" refer to directions toward and away from, respectively, the geometric center of a particular component.

As shown in fig. 1 and fig. 2, the technical solution adopted by the present invention is as follows: the high stability diaphragm type metal end cover for desicator that this scheme provided, including diaphragm type stick, a protection sleeve section of thick bamboo, end cover and fixed bolster, a protection sleeve section of thick bamboo is hollow columnar structure, and in the protection sleeve section of thick bamboo was located to the diaphragm type stick, the diaphragm type stick both ends outside was equipped with the external screw thread, and the end cover inboard is equipped with the internal thread, and the end cover is equipped with two sets ofly, and diaphragm type stick both ends are located through threaded connection to two sets of end covers, and the fixed bolster is located on the end cover, is equipped with the fixed orifices on the fixed bolster.

As shown in fig. 1, the membrane-type rod, the protective sleeve, the end cover and the fixed support are all made of aluminum alloy.

As shown in figure 3, the circumference of the inner side wall of the end cover is provided with grooves, the grooves are positioned above the inner threads of the end cover, and O-shaped rings are arranged between the grooves.

During specific use, put into protecting sleeve 2 earlier the diaphragm type stick 1, then put end cover 3 and diaphragm type stick 1 in place through threaded connection, later place the position that needs put with whole device, tightly fix end cover 3 and connecting device through fixed orifices 5 at last, because aluminum alloy material has been adopted, whole end cover 3's intensity is very high, even be in vibration high pressure operational environment, also be difficult for the dropout, use fixed bolster 4 to further improve end cover 3's reliability more, in addition, metallic resistant high low temperature is resistant, corrosion resisting capability also obviously is superior to PVC, cooperation O type circle 6 can play fine leakproofness, whole end cover 3's stability greatly increased.

It is noted that, herein, relational terms such as first and second, and the like may be used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions. Furthermore, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus.
