Description

Capsule type gas filter

Technical Field

The utility model relates to a separation technical field, concretely relates to capsule type gas filter who is used for gas-solid separation and collection in the gas, reduces the pollution of emission.

Background

With the rapid development and application of advanced technologies, the demand for gas in life or industrial production is higher and higher, especially in the industries of environmental protection, new energy, pharmacy, food and the like.

The types of the commonly used gas filters are many at present; the filter is not suitable for small-flow, mini-type and high-purity gas filters, and the application requirements of the fields requiring mini-type and small-flow filters are far from being met.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a wholly can dismantle, can change the filter core, and be applicable to the filterable miniature capsule type gas filter of low discharge high-purity gas.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

the utility model provides a capsule type gas filter, includes filter housing, filter housing's one end and air inlet joint intercommunication, filter housing's the other end is connected the filter and is gone up the cap, the gas outlet that is equipped with the intercommunication on the filter goes up the cap connects, be equipped with the filter core in the filter housing, the filter core is connected with the one end of filter upper hat to it is sealed through O type circle.

Preferably, the filter housing and the filter upper cap are both of a structure with one open end, and the one open end of the filter housing and the one open end of the filter upper cap are mutually inserted.

Preferably, the filter upper cap is in threaded connection with the filter housing.

Preferably, the filter upper cap and the filter shell are sealed by a filter O-ring.

Preferably, the air outlet joint and the air inlet joint both adopt the structures of bamboo joint pipes and quick plugs.

Preferably, a spring is arranged in the filter element and used as a keel for supporting the filter element.

The filter element 4 and the filter upper cap 2 of the utility model are sealed by O-shaped rings, and the sealing performance is good; because the filter upper cap 2 adopts threaded connection with filter housing 5, wholly can dismantle, has had the renew cartridge 4 of using, just the utility model is suitable for a low discharge high-purity gas filters, has widened the applied basin of filter, has satisfied the demand in market.

Reference numbers in the figures:

1. an air outlet joint; 2. a filter is covered; 3. a 0-shaped ring of the filter; 4. a filter element; 5. a filter housing; 6. an air inlet joint.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

As shown in fig. 1 and fig. 2, for the present invention provides a capsule type gas filter, which comprises a filter housing 5 with an open structure and an upper filter cap 2 with an open structure, wherein the open structure at one end of the filter housing 5 is correspondingly connected with the open structure at one end of the upper filter cap 2 through a thread, and is sealed by a filter O-ring 3; the other end of the filter shell 5 is welded and communicated with an air inlet joint 6;

a filter element 4 is arranged in the filter shell 5, a spring is arranged in the filter element 4 and is used as a keel for supporting the filter element 4, two sides of the filter element 4 are fixed in the filter upper cap 2 in a sealing manner through O-shaped rings, an air outlet joint 1 communicated with the interior of the filter upper cap 2 is welded outside the filter upper cap 2, and the air outlet joint 1 is communicated with the filter element 4 in the filter upper cap 2;

furthermore, the filter has small structural size, and the air outlet joint and the air inlet joint both adopt the structural styles of bamboo joint pipes and quick plugs, so that the quick installation and maintenance are facilitated.

The utility model discloses a capsule type gas filter theory of operation as follows:

gas gets into from air inlet joint 6 the utility model discloses an in the filter, gaseous filter layer all around along filter core 4 gets into filter core 4 to filter through filter core 4, solid particle in the gas is intercepted by filter layer 4 all around, and clean gas passes through the inside of filter core 4, and connects 1 discharge through the gas outlet.

The filter element 4 and the filter upper cap 2 of the utility model are sealed by O-shaped rings, and the sealing performance is good; because the filter upper cap 2 and the filter shell 5 are in threaded connection and can be integrally disassembled, the filter element 4 can be replaced.

In the description of the present invention, it is to be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and to simplify the description, but do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore should not be construed as limiting the present invention.
