Gas is uneven, and the powder easily conveyed blocks.
The content of the invention
In view of the above-mentioned problems of the prior art, the utility model provides a kind of air supporting piece, the air supporting piece resistance to pressure is strong,
It is non-breakable, also not also aging, in addition, the air supporting piece even air hole distribution, aeration is good, the powder that is not easy to be conveyed blocks up
Plug.
To achieve these goals, the utility model provides a kind of air supporting piece, including hollow ventilation bolt, has inner chamber
Housing and hard metal material screen cloth is made, the housing is made up of hard metal material, and is in flat, the upper end of housing
Opening, the screen cloth are located at housing upper end open, and the ventilation bolt is fixedly connected on one of the housing away from opening
Side and connected with the inner chamber of housing.
In the technical scheme, by making shell be made using hard metal material, the compressive resistance of housing can be increased, entered
And it can prevent housing from the problem of broken and easy to aging occurring in feeding process.Meanwhile the one side for making to contact with powder is adopted
With the screen cloth made of hard metal material, so the venthole of air supporting piece can be made to be of moderate size, and can guarantee that going out for air supporting piece
The distribution of stomata is more uniform, and then can obtain good aeration, and the venthole on air supporting piece can be made to be not easy by powder institute
Block, and can guarantee that air supporting piece has preferable compressive resistance.
Further, in order to improve the air permeability of the air supporting piece, and air inflow can further be increased, so that powder is not easily blocked
The mesh of screen cloth, the cross section of the housing is rectangular, and the quantity of the ventilation bolt is two, and two ventilation bolts are symmetrically
It is connected to the left and right sides of housing.
Further, in order that overall dimensions are smaller, to improve its versatility, the thickness of the housing is 6mm, the thickness of screen cloth
Spend for 3mm.
Further, in order to improve the compressive resistance of screen cloth, the section of the screen cloth is in frustum type.
Further, in order to prevent corrosion, and compressive resistance is can guarantee that, the housing and screen cloth use stainless steel material system
Into.
Further, in order that air supporting piece has longer service life, the screen cloth and the opening of housing upper end pass through
Resistance welding method welds, and is welded between the ventilation bolt and housing by resistance welding method.
Further, for the ease of with tank body or pipeline carry out it is sealed defend tenaciously, include being set in and ventilate on the outside of bolt
Rubber blanket and pad, and the nut being connected with ventilation bolt thread.

Embodiment
The utility model is described in further detail below.
As shown in Figures 1 to 6, a kind of air supporting piece, including hollow ventilation bolt 3, the housing 2 and hard gold with inner chamber
Screen cloth 1 is made in category material, and the housing 2 is made up of hard metal material, and is in flat, the upper end open of housing 2, the sieve
Net 1 is located at the upper end open of housing 2, and the ventilation bolt 3 is fixedly connected on the side of the housing 2 away from opening and and shell
The inner chamber connection of body 2.By making shell 2 be made using hard metal material, the compressive resistance of housing 2 can be increased, and then can be with
Prevent housing 2 from the problem of broken and easy to aging occurring in feeding process.Meanwhile the one side for making to contact with powder is used by hard
Screen cloth 1 made of matter metal material, so can make the venthole of air supporting piece be of moderate size, and can guarantee that the venthole of air supporting piece
Distribution is more uniform, and then can obtain good aeration, and the venthole on air supporting piece can be made to be not easy to be blocked by powder, and
It can guarantee that air supporting piece has preferable compressive resistance.
In order to improve the air permeability of the air supporting piece, and it can further increase air inflow, so that powder is not easily blocked screen cloth 1
Mesh, the cross section of the housing 2 is rectangular, and the quantity of the ventilation bolt 3 is two, and two ventilation bolts 3 symmetrically connect
It is connected on the left and right sides of housing 2.Two ventilation bolts 3 can use diplopore air blast, and then can increase air inflow.
In order that overall dimensions are smaller, to improve its versatility, the thickness of the housing 2 is 3mm, and the thickness of screen cloth 1 is
3mm, the overall size of such air supporting piece is 6mm.
In order to improve the compressive resistance of screen cloth, the section of the screen cloth 1 is in frustum type.
In order to prevent corrosion, and compressive resistance is can guarantee that, the housing 2 and screen cloth 1 are made of stainless steel material.It is logical
Crossing housing 2 made of stainless steel and screen cloth 1 can make the overall dimensions of air supporting piece smaller, narrow so as to make it more easily be installed on
In small space in long pipeline or inside tank body 7.
In order that air supporting piece has longer service life, the screen cloth 1 and the opening of the upper end of housing 2 pass through electric resistance welding
Connection is welded, and is welded between the ventilation bolt 3 and housing 2 by resistance welding method.Resistance welding method can guarantee that screen cloth 1 and shell
Other metals will not be mixed between body 2, between ventilation bolt 3 and housing 2, are caused so as to be avoided that because of other metals of incorporation
The situation that cell reaction easily occurs in atmosphere occur, and then can increase the service life.
For the ease of carrying out the sealed rubber blanket 4 defended tenaciously, include being set on the outside of ventilation bolt 3 with tank body or pipeline
With pad 5, and the nut 6 being threadedly coupled with ventilation bolt 3.
As shown in figure 4, Fig. 4 shows the air supporting piece and is satisfied with the structural representation on tank body 7.By air supporting piece from interior court
It is outer to be affixed on installation surface, rubber blanket 4 is first installed on bolt 3 of ventilating, to prevent the later stage into the gas overflowing in tank body 7, then
Bolt 3 of ventilating installs pad to increase contact area after passing through tank body 7, is finally fixed with nut 6.Make to pacify on ventilation bolt 3 again
Pneumatic transmission Quick-mounting joint is filled, with for connecting compressed air source unit.So, when each material falls or falls slow, ventilation is opened
Take offence floating piece, material can be made normally to fall.
