Technical field
The utility model relates to a kind of filtrating equipment, relates in particular to a kind of sedimeter that is provided with filter core.
Background technique
Hot-strip is carrying out the cold rolling man-hour that adds, and needs to use emulsified liquid as the technological lubrication medium.Emulsified liquid is formulated by a certain percentage by ROLLING OIL and water, and it forms oil film by nozzle ejection to roller gap.Generally, emulsified liquid recycles, and promptly the emulsified liquid that ejects of milling train reclaims by collecting tank, and circulation turns back to milling train and continues to use once more.In cyclic process, can comprise solid particulate matters such as the iron powder that produces in the more operation of rolling, greasy filth in the emulsified liquid, will cause band steel plate planar defect if be directly injected to roll gap, therefore must be filtered removal.
More common filter method is to adopt cartridge filter at present, the built-in filter core of filter, and the filter stick surface has tiny filter opening, and when liquid passed through from filter opening, solid particulate matter was left in the filter core, reaches the purpose to liquid filtering.The shortcoming of this filter is, the filter residue that remains in filter core inside can't in time be removed, and along with the increase of filter life cycle, filtering effect can variation.Therefore, need regularly filter to be disintegrated and labor cleaning's filter residue, frequency of maintenance and maintenance cost are higher.
Summary of the invention
The purpose of this utility model provides a kind of filter core self-cleaning type liquid filter, it can not only filter the liquid that is mixed with solid impurity, can also realize the automated cleaning of filter core by the pressure difference of flow of fluid, thereby reduce the disintegration wash number of filter, improve filter efficiency when improving filter quality, and reduce the time and the cost of plant maintenance.
In order to realize the foregoing invention purpose, the utility model provides a kind of filter core self-cleaning type liquid filter, and it comprises the filter body of a hollow, is provided with the filter stick that plurality of vertical is provided with in the described filter body; One discharge pipe, a liquid inlet pipe and a feed pipe are communicated with described filter body respectively, and described liquid inlet pipe is provided with a feed liquor valve; In addition, described filter core self-cleaning type liquid filter also comprises:
One drive plate has several filter stick holes on it, described each filter stick correspondence respectively runs through each filter stick hole setting;
One drive motor, it is connected with described drive plate, drives drive plate and rotates around its how much axle center;
One filter stick chassis, its below that is fixed at described filter stick is divided into a upper cavity and a lower chamber with described filter body, described lower chamber respectively with described discharge pipe and liquid inlet pipe conducting, described upper cavity and described feed pipe conducting, described filter stick has several inlet openings on the chassis, described each inlet opening and each corresponding conducting in filter stick lower end also have a backwash liquid outlet opening on the described filter stick chassis;
One filter stick is taken over a business, and it is fixed at the top of described filter stick, has a backwash inlet opening on described filter stick is taken over a business;
One backwash liquid inlet pipe, the one end is communicated with described feed pipe, and its other end is communicated with described backwash inlet opening, and described backwash liquid inlet pipe is provided with a backwash feed liquor valve;
One backwash drain pipe, it is communicated with described backwash liquid outlet opening.
Preferably, described filter core self-cleaning type liquid filter also comprises a reflow pipe, and it is communicated with described backwash drain pipe, and described reflow pipe is provided with a reflux valve.
The using method of filter core self-cleaning type liquid filter described in the utility model is:
1. when using this filter to filter: liquid enters filter by lower chamber, enter filter stick by inlet opening, filter out solid particle in the liquid through filter stick after, filtrate enters upper cavity, enter feed pipe by upper cavity again, be delivered to the working equipment that needs to use liquid by feed pipe.
2. through after a while filtration, in the time of need cleaning filter stick: drive motor rotates position, a hole, make the backwash inlet opening, filter stick and the alignment of backwash liquid outlet opening, form a path, backwash feed liquor valve and reflux valve are opened then, this moment is through filtered liquid process feed pipe, the backwash liquid inlet pipe, the backwash inlet opening enters filter stick, filter stick is washed, liquid after the flushing is through the backwash liquid outlet opening, the backwash drain pipe flows out, waste for the liquid after preventing to wash, make liquid flow into reflow pipe through the backwash drain pipe, be delivered to the liquid storage case by reflow pipe again, wait for the filtration of next round, can significantly reduce the use amount of liquid like this.When above-mentioned backwash process carries out, liquid in the upper cavity can oppositely enter filter stick inside by filter opening under the effect of pressure, thereby also filter stick is carried out flushing action, flow out from the backwash drain pipe via the backwash liquid outlet opening equally through the liquid that washes.After above-mentioned steps was carried out a period of time, drive motor rotated position, a hole once more, began next root filter stick is washed cleaning.Repeat above-mentioned steps, can continually carry out automatically cleaning, thereby keep the filter precision and the filtering effect of filter integral body to maintain a level preferably all the time all filter sticks.
Filter core self-cleaning type liquid filter described in the utility model, by backwashing system is set, make the filter stick of being located in the filter (or being called filter core) can realize self-cleaning cleaning, thereby avoided the frequent disintegration of filter to clean, when improving the filter filtering effect, can also significantly reduce its frequency of maintenance, thereby reduce maintenance cost.
