Embodiment
Refering to Fig. 1,2, a kind of relief valve unloading gas filter, including shell 1, air inlet 2, just Uniform air grid panel 3, effect
Filter cotton 4, high efficiency filter cotton 5, air outlet 6, maintenance door 7, differential pressure pickup 8, the monnolithic case of shell 1 is cuboid, shell 1
Inside be in hollow structure；One side of shell 1, which is truncated on rear edge, is formed with fixed border 11, fixed border 11
Upper to be connected with maintenance door 7 by hinge hinge, maintenance door 7 is appearance and size identical two, and two maintenance doors 7 are in specular
On a side of shell 1, and to ensure that two maintenance doors 7 merge the formation that upper rear and shell 1 can fit together perfectly
One containment housing, can so avoid mating surface of the air between maintenance door 7 and shell 1 from leaking out, the side of maintenance door 7
It is provided with frame on another side adjacent on door handle 71, shell 1 and is provided with air outlet 6, the quantity of air outlet 6 is some
It is individual and overall in being distributed on another side unevenly, square through hole (figure is not marked), shell are provided with the end face of shell 1
Air inlet 2 is consolidated with 1 square through hole, specifically, air inlet 2 is placed on the end face side of shell 1, the outside of air inlet 2
It is provided with the hole 21 that is connected on frame, air inlet 2 is by being connected hole 21 and the pipeline (not shown) of relief valve is fixedly connected on
Together, differential pressure pickup 8 is installed, the half of differential pressure pickup 8 is submerged in the inside of shell 1 on the end face opposite side of shell 1
In, the inside of shell 1 has been sequentially inserted into Uniform air grid panel 3, primarily efficient filter wool 4, high efficiency filter cotton 5, and Uniform air grid panel 3 is placed on
Close to one end of air inlet 2, Turbogrid plates 3 are in the inner side of air inlet 2, this belt transect dust gas in the fixed position of the end face of shell 1
Body can only initially pass through Uniform air grid panel 3 after the entrance of air inlet 2, and Uniform air grid panel 3 plays a part of shunting, can be in sinuous flow
Gas is divided into multiple fluid layers, so that gas is faster through primarily efficient filter wool 4 and high efficiency filter cotton 5, by filtered air
Diffused out from air outlet 6 in uniform air flow, that is, formed on laminar condition, the top layer of Uniform air grid panel 3 and be coated with zinc layers, zinc layers are played
Antiseptic and rustproof function, Uniform air grid panel 3, which can use the longer time and reduce, changes number of times, and primarily efficient filter wool 4 is placed in
Between air grid panel 3 and high efficiency filter cotton 5, high efficiency filter cotton 5 is disposed close to one end of air outlet 6, and differential pressure pickup 8 is distinguished
Installed in primarily efficient filter wool 4 and the both sides of high efficiency filter cotton 5, the material of primarily efficient filter wool 4 is polyester fiber, primarily efficient filter wool 4
Mesh spacing≤5 μm, the material of high efficiency filter cotton 5 is polyester fiber, and high efficiency filter cotton 5 is by impregnation and drying and shaping technique
After form integrative-structure, dust particle is not passed through because of the complete permeating medium of stick, make comprehensive filtered air air-flow equal
Even diffusion, this structure enables the higher filter efficiency of the holding of high efficiency filter cotton 5 and dust containing capacity, the outlet air surface of high efficiency filter cotton 5
One layer of grid knitmesh is fitted with, the service life of high efficiency filter cotton 5 can be extended by increasing grid knitmesh, when primarily efficient filter wool 4
With being blocked after the prolonged adsorption of dust of high efficiency filter cotton 5, and cause primarily efficient filter wool 4 and the both sides of high efficiency filter cotton 5
Pressure differential exceeds the value that differential pressure pickup 8 is set, and the alarm (not shown) of the at this moment supporting connection of differential pressure pickup 8 starts work
Make, point out user to need the dust cleared up primarily efficient filter wool 4 with adsorbed on high efficiency filter cotton 5, at this moment open maintenance door 7, extract out
Primarily efficient filter wool 4 and high efficiency filter cotton 5 and the region cleaning dust specified in factory, it is to avoid secondary pollution.
When in use, air inlet 2 is connected relief valve unloading gas filter by the hole 21 that is connected with relief valve, pressure release
The band dusty gas of valve unloading is entered inside shell 1 by air inlet 2, band dusty gas first by Uniform air grid panel 3, due to
Uniform air grid panel 3 plays a part of shunting, and band dusty gas uniformly passes through primarily efficient filter wool 4, and larger dust granules are inhaled
It is attached on primarily efficient filter wool 4, less dust granules are can to pass through primarily efficient filter wool 4, but containing smaller dust granules
When gas is by high efficiency filter cotton 5, less dust granules are adsorbed on high efficiency filter cotton 5, the gas after filtration, purification
Body directly can be emitted in workshop by air outlet 6.
The above-described embodiments are merely illustrative of preferred embodiments of the present invention, not to the structure of the present invention
Think and scope is defined.On the premise of design concept of the present invention is not departed from, technology of this area ordinary person to the present invention
The all variations and modifications that scheme is made, all should drop into protection scope of the present invention, claimed technology contents of the invention,
All record in detail in the claims.
