Description
Technical field
This utility model relates to a kind of PO PE NT PTFE, specifically refers to a kind of PO PE NT PTFE being easy to observe ventilation.
Background technology
At present, it is known that building materials, chemical industry, the Workplace powder ash of the industries such as metallurgy and mining is big, and contains in dust
Moisture, needs dust arrester to remove powder ash, and PO PE NT PTFE device is the one in dust arrester.By filter bag to having relatively
The air of high concentration dust filters, and air is discharged along the bag face of filter bag, and the dust in air is then blocked and is placed in filter
Bag is internal.But the humidity in some air to be filtered is higher, the dust large area being easy for occurring being filtered is attached to filter bag
Situation on bag face, causes exhaust velocity slow, affects filter efficiency, even occurs because of the reduction of exhaust velocity producing
Security incident.Therefore, designing a PO PE NT PTFE that can observe ventilation in time is research purpose of the present utility model.
Utility model content
The weak point existed for above-mentioned prior art, this utility model is to provide a kind of acupuncture being easy to observe ventilation
Felt filter bag, it is possible to effectively solve the problem that above-mentioned prior art exists.
The technical solution of the utility model is:
A kind of PO PE NT PTFE being easy to observe ventilation, including filter bag body, filter bag frame and ring spring, described filter bag
The top of body is provided with corresponding air inlet, and described filter bag frame is installed on described filter bag originally along the air inlet of described filter bag body
Internal portion, ovalisation shape when described filter bag body struts, described ring spring positioner is in the centre of described filter bag body
On position, the centre position of described filter bag body is tightened on described filter bag frame by described ring spring；Described filter bag body
Centre position on be connected with a circle for being coated with the location lasso of described ring spring, described location lasso is by Nomex material
Material is prepared from, and location lasso uses the mode sewed up to be secured on described filter bag body.
Described filter bag frame comprises circular orientation circle and lower circular orientation circle, described upper circular orientation circle and lower circular orientation circle
Between by being angularly distributed with multiple corresponding support bar.
Implement the technical solution of the utility model, have the advantages that
Ovalisation shape when filter bag body of the present utility model struts, ring spring positioner is in the centre position of described filter bag body
On, the centre position of filter bag body is tightened on described filter bag frame.When filtering at the beginning, the bag face of filter bag body
On there is no adhesive dust, ventilation is enough, and under the effect of ring spring, filter bag body becomes Pear-Shaped to be exhausted, along with
Filter amount of dust increase, the dust filtered starts progressively large area and is attached to the bag face of filter bag body, ventilation progressively under
Fall, then ring spring is slowly strutted by filter bag body, just can effectively judge ventilation by the amount of strutting of filter bag body, with
It is easy to the filter bag body that ventilation is too low is disposed (replace new filter bag body or pat filter bag body), improves ventilation,
Prevent filter efficiency from reducing and because of the reduction of exhaust velocity, work safety accident occur.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is use state diagram of the present utility model.
Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawing, to this practicality
Novel it is described in further detail.
With reference to Fig. 1-2, a kind of PO PE NT PTFE being easy to observe ventilation, including filter bag body 1, filter bag frame 2 and ring
Shape spring 3, the top of described filter bag body 1 is provided with corresponding air inlet 11, and described filter bag frame 2 is along described filter bag body
It is internal that the air inlet 11 of 1 is installed on described filter bag body 1, ovalisation shape when described filter bag body 1 struts, described annular
Spring-positioning device is on the centre position of described filter bag body 1, and described ring spring 3 is by the centre of described filter bag body 1
Position is tightened on described filter bag frame 2；A circle it is connected with for being coated with described ring on the centre position of described filter bag body 1
The location lasso 12 of shape spring 3, described location lasso 12 is to be prepared from by needle felt material, and location lasso 12 uses seam
The mode closed is secured on described filter bag body 1.
Described filter bag frame 2 comprises circular orientation circle 21 and lower circular orientation circle 22, described upper circular orientation circle 21 and under
By being angularly distributed with multiple corresponding support bar 23 between circular orientation circle 22.
When filtering at the beginning, the bag face of filter bag body 1 not having adhesive dust, ventilation is enough, at ring spring 3
Effect under, filter bag body 1 becomes Pear-Shaped to be exhausted, along with filter amount of dust increase, the dust filtered start by
Step large area is attached on the bag face of filter bag body 1, and ventilation progressively declines, then ring spring 3 is slowly by filter bag body 1
Strut, just can effectively be judged ventilation by the amount of strutting of filter bag body 1, in order to the filter bag body too low to ventilation
1 is disposed (replace new filter bag body or pat filter bag body), improves ventilation, prevents filter efficiency from reducing and because row
The reduction of gas speed and work safety accident occurs.
The above is only preferred implementation of the present utility model, it is noted that for the ordinary skill people of the art
For Yuan, on the premise of without departing from this utility model principle, it is also possible to make some improvements and modifications, these improve and profit
Decorations also should be regarded as protection domain of the present utility model.
