Technical Field
The utility model relates to a fields such as marine oil development machinery technical field, municipal sewage treatment, production running water treatment, more specifically relate to a but online washing blowdown formula filter.
Background
The filter is installed on the pipeline for conveying medium, so that the fluid to be used can pass through the filter smoothly, and the unwanted solid matters are retained. Filters are usually installed at the site of the pretreatment process of the material, for example: including pressure relief valves, pressure reducing valves, pneumatic control valves, etc. After the fluid is filtered by the filter, filtering impurities can be remained in the filter screen, and the filtering operation is difficult to carry out when the filtering impurities are too much, so that the production equipment connected with the filter needs to be stopped for production, the filter cartridge or the filter screen in the filter needs to be taken out during cleaning, the filter cartridge or the filter screen is put into the filter again after cleaning, and the whole cleaning operation is time-consuming and labor-consuming and is not beneficial to the improvement of the production efficiency.
SUMMERY OF THE UTILITY MODEL
In order to overcome exist not enough among the above-mentioned prior art, the utility model provides a can wash blowdown formula filter on line has online filtration and cleaning function, does not need the shut down production isolation to the washing of filter and dismantles to can remove numerous and diverse filter screen from and dismantle the step, labour saving and time saving, ensured the continuity of production, improved work efficiency greatly.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
the on-line flushing sewage filter comprises a filter screen and a basket filter body, wherein a filter screen sewage flushing channel communicated with an inner space is arranged on the bottom side of the inner space of the basket filter body, a filtering fluid inlet is formed in one side of the inner space of the basket filter body, a filtering fluid outlet is correspondingly formed in the other side of the inner space and the filtering fluid inlet, a cylindrical filter screen is arranged in the inner space of the basket filter body, a through hole corresponding to the filter screen sewage flushing channel is formed in the bottom side of the filter screen, the top end of the filter screen is lower than the filtering fluid inlet, the filtering fluid outlet is covered by one side of the filter screen, an automatic sewage discharging control valve is arranged in the filter screen sewage flushing channel, and the automatic control valve is electrically connected with a pressure difference/timing controller.
The top end of the filter screen is connected with the contact sealing plane of the filter screen and the basket filter body in a sealing mode.
The bottom end of the filter screen is hermetically connected with a contact sealing surface of the filter screen and the filter screen sewage flushing channel.
The filtered fluid outlet is disposed at a position lower than the filtered fluid inlet.
The beneficial effects of the utility model reside in that: when remaining impurity need clear up in the filter, only need switch on online blowdown flow, directly through washing the flow, realize that the inside impurity of filter washs, after the washing, direct isolation online wash blowdown flow can.
The utility model discloses can realize the online cleaning function of filter, have very big meaning to needs continuous production technology, when reducing work load in a large number, ensure the continuity of production.
Drawings
The present invention is further explained by using the drawings, but the embodiments in the drawings do not constitute any limitation to the present invention, and for those skilled in the art, other drawings can be obtained according to the following drawings without any inventive work.
Fig. 1 is a schematic view of the overall structure of the present invention.
In the figure: the filter comprises a filter fluid inlet 1, a filter fluid outlet 2, a filter screen blowdown flushing channel 3, a filter screen 4, a filter screen 5, a basket filter body contact sealing plane, a filter screen 6, a filter screen blowdown flushing channel contact sealing plane, a blowdown automatic control valve 7, a differential pressure/timing controller 8 and a basket filter body 9.
