Abstract

The utility model discloses a backwashing basket type filter and relates to a novel filter used for refined oil product long-distance pipelines. The filter comprises a cylinder body, an inlet, an outlet, a filtering framework, a drain outlet, an exhaust pipe and a valve; the filtering framework is reversely installed in the cylinder body and provided with a circular section; the inlet is lower than the outlet; and a slag outlet is arranged at a bottom of the cylinder body. The section of the filtering framework further can be designed as arc; a baffle plate capable of changing the flowing direction is mounted in the cylinder body; and the inlet and the outlet are on the sample plate at the moment. A quick opening device is mounted above the cylinder body. Through the adoption of the reversed basket type filtering framework, large-particle iron rust can be naturally sunk to the bottom; the backwashing of the filtering framework is instantly achieved by using an outlet medium without taking out the filtering framework; the slag can be directly discharged out of the bottom, so that the filter is easily and simply maintained and cleaned, the service life of the filtering net is prolonged, the filtering effect is enhanced, and the normal use of other apparatuses and the oil product quality are guaranteed. Through the adoption of low feeding and high discharging, the flowing direction of the liquid is completely changed, all the filtering areas of a filtering net can fully play a role of filtering, and local block of the filtering net is completely avoided.

Description

The backwash basket filter
Technical field
The utility model relates to a kind of filter for Product Oil Transmission Pipeline, is a kind of filter with backwashing function specifically.
Background technology
Present common basket filter, there is defective in its structural design, and for example: filter frame adopts usual manner to be placed in the filter, because it is very near to import and export distance, liquid directly advances directly, and uses a period of time, and local clogging will appear in the filter screen between the import and export.In addition, adopt common filter frame volume little, filter multiple and only be 2 ~ 3 times, filter frame needs frequent the unlatching to clean, and very easily damages filter screen; Not equipped fast opening blind above filter, unlatching is wasted time and energy; The bottom does not arrange slag-drip opening, the filtration indigo plant of overworking iron rust can only be mentioned, and could take out iron rust.
Summary of the invention
In order to solve the technical problem of above-mentioned existence, the utility model provides a kind of backwashing function that has, good filtration effect, the backwash basket filter of filter screen long service life.
The purpose of this utility model is achieved through the following technical solutions: the backwash basket filter, comprise cylindrical shell, import, outlet, filter frame, sewage draining exit, blast pipe, valve, it is characterized in that: described filter frame is inverted and is installed in the cylindrical shell, its cross section is circular, described import is lower than the height of outlet, at cylinder body bottom slag-drip opening is set.
The backwash basket filter, comprise cylindrical shell, import, outlet, filter frame, sewage draining exit, blast pipe, valve, it is characterized in that: described filter frame is inverted and is installed in the cylindrical shell, its cross section is arc, the deflection plate that can change the flow direction is installed in cylindrical shell, and described import and outlet arrange slag-drip opening at cylinder body bottom on same level.
Quick opening is installed in described cylindrical shell top.
Described quick opening comprises fast opening blind, fast opening blind pivoted arm, and the fast opening blind sealing is adopted at the top of cylindrical shell, and fast opening blind is connected with the fast opening blind pivoted arm.
Described quick opening comprises flange end socket and end socket pivoted arm, and the sealing of flange end socket is adopted at the top of cylindrical shell, and the flange end socket is connected with the end socket pivoted arm.
The backwash observation panel is installed on the described cylindrical shell.
The beneficial effects of the utility model: the utility model adopts said structure, adopted inverted blue formula filter frame, make the iron rust natural subsidence of larger particles to the bottom, can realize back flush to filter frame in the situation that do not take out filter frame, and can be in the bottom direct deslagging, so that safeguard that cleaning is simple and easy to do, and prolonged the service life of filter screen and improved filter effect, normal use and the oil quality of station miscellaneous equipment guaranteed.Fluid media (medium) enters and adopts the low in and high out form in the cylindrical shell, thereby has thoroughly changed the flow direction of liquid, make all filter areas of filter screen all can give full play to filtering function, has solved the problem that normal blue formula filter very easily stops up filter screen.Utilize the outlet medium can realize back flush to filter frame in the situation that do not take out filter frame, and can be in the bottom direct deslagging so that safeguard that cleaning is simple and easy to do.Because adopting quick opening (fast opening blind or flange end socket) greatly to reduce, the cylindrical shell top repairs and the labour intensity of changing filter screen.

The specific embodiment
Embodiment 1:
The backwash basket filter as shown in Figure 1, 2, comprises cylindrical shell 1, supporting leg 2, is provided with import 3, outlet 4 at cylindrical shell 1, and import 3 is lower than the height of outlet 4.In cylindrical shell 1, be provided with inverted circular filter frame 5, be provided with sewage draining exit 6, slag-drip opening 7, blast pipe 8, backwash observation panel 9 at cylindrical shell 1.At the top of cylindrical shell 1 fast opening blind 10 is set, fast opening blind 10 is connected with fast opening blind pivoted arm 11.
Embodiment 2:
The backwash basket filter shown in Fig. 3,4, comprises cylindrical shell 1, supporting leg 2, is provided with import 3, outlet 4 at cylindrical shell 1, and import 3 is lower than the height of outlet 4.In cylindrical shell 1, be provided with inverted circular filter frame 5, be provided with sewage draining exit 6, slag-drip opening 7, blast pipe 8, backwash observation panel 9 at cylindrical shell 1.At the top of cylindrical shell 1 flange end socket 12 is set, flange end socket 12 is connected with end socket pivoted arm 13.
Embodiment 3:
The backwash basket filter shown in Fig. 5,6, comprises cylindrical shell 1, supporting leg 2, is provided with import 3, outlet 4 at cylindrical shell 1, is provided with inverted arc filter frame 5 in cylindrical shell 1, and at cylindrical shell 1 interior installation deflection plate 14, import 3 and outlet 4 are on same level.Be provided with sewage draining exit 6, slag-drip opening 7, blast pipe 8, backwash observation panel 9 at cylindrical shell 1.At the top of cylindrical shell 1 flange end socket 12 is set, flange end socket 12 is connected with end socket pivoted arm 13.
Operation principle of the present utility model:
