Background technology
High-quality strip cold rolling mills production technology is more demanding to lubrication and rolling process, emulsify fluid circulation stability and
Safety is most important for the cold-rolling process of high standard.Vacuum filter is the important dress emulsified in fluid circulation
It puts, be mainly used for filtering and intercept the graininess impurity in emulsion.The work principle of filter of vacuum filter is using filter paper as filtering
Medium carries out machinery and screens out, and filter paper carries out retention separation by its pore size to the particle in emulsion, with the operation of system,
Impurity on filter paper is continuously increased, and emulsion is also gradually increasing by the resistance of filter paper, and the pressure difference of filter chamber and vacuum chamber will
Can gradually it increase, after pressure difference reaches setting value, filter paper replacement process automatic running.
The pressure pulse that the vacuum breaker pneumatic operated valve quickly opened before paper feed will generate a moment suction, this pulse can draw
The sharp pounding of vacuum breaker pipeline is played, further, since vacuum breaker pipeline is very long and there are many corners, is further exacerbated by
The vibrations of pipeline.Under strong vibrations interference, the screw of vacuum breaker pipeline flange junction can often loosen, clip for pipe
Also it can loosen, more seriously also often be shattered at the weld bond of pipeline, so as to cause the leakage of emulsion, emulsion is a kind of
Oil water mixture, the welding of pipeline belong to superfine and get angry, and not only result in the increase of production cost, also there are larger safety
Hidden danger.
Utility model content
The purpose of this utility model is that for the drawback of the prior art, a kind of vacuum filter with shock-absorbing function is provided
System breaks down to avoid vacuum breaker pipeline, reduces pipeline maintenance cost, eliminates safe hidden trouble.
Problem described in the utility model is realized with following technical proposals：
A kind of vacuum filtering system with shock-absorbing function, composition include vacuum filter, vacuum pump and vacuum breaker pipe
Road, the inlet of the filter chamber of the vacuum filter suck emulsion to be filtered by carrying the inlet tube of liquid feed valve, very
The liquid outlet of the vacuum chamber of air filter connects successively through the inlet tube of liquid valve and vacuum pump and magnetic filter, described broken true
The head end of vacant duct and the inlet tube of magnetic filter connect, and tail end is connected by the vacuum chamber of pneumatic operated valve and vacuum filter,
Check valve is additionally provided between the head end and air of vacuum breaker pipeline.
The above-mentioned vacuum filtering system with shock-absorbing function, the inlet tube of the filter chamber of the vacuum filter and magnetic mistake
It is connected between the inlet tube of filter by bypass valve.
The above-mentioned vacuum filtering system with shock-absorbing function, the vacuum pump set two, and two vacuum pumps are used in parallel.
The above-mentioned vacuum filtering system with shock-absorbing function, the Opening pressure of the check valve is 2bar.
The utility model is acted on using the pressure regulation of check valve and the vacuum degree of vacuum breaker pipeline is limited in certain range,
The strenuous vibration of vacuum breaker pipeline is effectively prevented, avoids the loosening of flange screw and clip for pipe, it is ensured that pipeline weld bond is not
Cracking, so as to reduce pipeline maintenance cost, eliminates security risk caused by superfine is got angry.In addition, the utility model also has
Have the advantages that simple in structure, easy to use.
Description of the drawings
The utility model is described in further detail below in conjunction with the accompanying drawings.
Fig. 1 is the structure diagram of the utility model.
It is marked in figure as follows：1st, vacuum filter, 2, liquid valve, 3, bypass valve, 4, magnetic filter, 5, vacuum pump, 6,
Vacuum breaker pipeline, 7, pneumatic operated valve, 8, liquid feed valve, 9, check valve.
Specific embodiment
The utility model provides a kind of vacuum apparatus for effectivelying prevent vacuum breaker pipeline sharp pounding.The device
Mainly by vacuum filter 1, liquid valve 2, bypass valve 3, magnetic filter 4, vacuum pump 5, vacuum breaker pipeline 6, pneumatic operated valve 7, into
Liquid valve 8 and check valve 9 form.
Vacuum filter 1 belongs to both surface filtration device, and machine is carried out to the graininess impurity in emulsion using filter paper as medium
Tool screens out, and filter paper carries out retention separation by its pore size to the particle in emulsion, since the iron powder impurity in emulsion is
Powdered molecule, smallest particles are less than 1 micron, and filtering accuracy can reach after particulate matter is forming cake layer on filter paper
The decades of times of filter paper precision.
The bottom of vacuum filter 1 is vacuum chamber, and top is filter chamber, is divided between filter chamber and vacuum chamber by porous plate
It opens, filter paper is placed on porous plate, is moved using the frictional force traction filter paper of chain angle bar, and subsequent filter paper is pushed out filter chamber,
Then it rolls up on waste paper reel.When the emulsion liquid level in filter chamber reaches high liquid level, vacuum pump 5 starts automatically, emulsion
Vacuum chamber is entered by filter chamber under the action of its dead weight and atmospheric pressure, after filter process, emulsion is sucked out by vacuum pump 5
And magnetic filter 4 is sent into, impurity is then adsorbed on filter paper.
Filter paper displacement apparatus is equipped in vacuum filter 1.With the operation of filtration system, the impurity on filter paper is constantly long-pending
Tired, emulsion is also gradually being increased by the resistance of filter paper, and the pressure difference of filter chamber and vacuum chamber will gradually increase, when pressure difference reaches
To after setting value, filter paper replacement process is by automatic running.First, vacuum pump 5 is out of service, and the pneumatic operated valve 7 of vacuum breaker pipeline 6 is beaten
It opens, the emulsion in the inlet tube of magnetic filter 4 will flow back into vacuum chamber, so as to eliminate between vacuum chamber and filter chamber
Pressure difference, then, chain drive electric motor starting, dirty filter paper is pushed out filter chamber and is rolled by reel, is drawn into stylish filter paper
In filter chamber.Presetting primary every 2 hours paper feeds, with the increase of filtering times, the diameter of waste paper volume gradually increases, and reaches and sets
After definite value, waste paper volume is unloaded, is wrapped with new filter paper again.
The check valve 9 that one pressure is 2bar is installed on the vacuum breaker pipeline 6 of vacuum filter 1（Check valve was opened and closed
Journey is repeated, and interval time was at 0.1 second or so）, for the pressure in control pipeline, and then achieve the purpose that damping.
The course of work of vacuum breaker pipeline：
When starting 7 moment of pneumatic operated valve, the pressure pulse of moment suction can be generated in vacuum breaker pipeline 6, causes vacuum breaker
The flow velocity of emulsion is accelerated in pipeline, therefore certain subnormal ambient can be formed inside vacuum breaker pipeline 6, meanwhile, along with
The quickening of flow velocity is emulsified, negative pressure is increasing, so caused vibrations also can more and more acutely.When in vacuum breaker pipeline 6
When negative pressure reaches the pressure threshold of check valve 9, check valve 9 can automatically open under the action of pressure difference, and the negative pressure inside pipeline 6 is just
It can reduce, vibrations reduce therewith；After the negative pressure drop in pipeline 6 is as low as certain value, check valve 9 will be automatically closed.Check valve 9
Use, can effectively reduce the vibrations of vacuum filter vacuum breaker pipeline 6, reduce the frequency that flange screw loosens, and can
To ensure that pipeline weld bond does not shatter, and then the leakage of the emulsion caused by vibrations is reduced, save production cost.
