Description

Technical Field

[0001] The utility model relates to the field of filters, in particular to a T-type pipeline filter. Background Art

[0002] T-type pipe filters are often used to filter impurities in the process of conveying liquids. T-type pipe filters are mainly composed of a tube shell, a filter element, a fixed flange and a flange cover. The flange cover and the fixed flange are fixedly connected by bolts, which on the one hand ensure the sealing of the T-type pipe filter and on the other hand press the filter element.

[0003] The announcement number is: CN219539588U, and the disclosure is "a T-type pipe filter, which relates to the field of fluid filtration technology. The utility model includes a T-type pipe body, a cover plate, a secondary filter element and a primary filter element. The T-type pipe body includes a horizontally placed main pipe and a branch pipe vertically penetrating and fixed in the middle of the peripheral side of the main pipe; a primary filter element is inserted in the main pipe; a beveled end cover is fixed at one end of the primary filter element close to the center of the main pipe, and a flow guide end cover is fixed at the other end of the primary filter element; a secondary filter element is inserted in the branch pipe; a reinforcing rod is fixed between the opposite surfaces of the upper end cover and the lower end cover. The utility model solves the problems of the single filter element design in the conventional T-type pipe filter, the lower end of which is easily damaged by liquid scouring, the insufficient strength, and the large liquid transportation resistance, and the single filter element design cannot ensure a high filtering accuracy by arranging a primary filter element, a secondary filter element, and a T-type pipe body";

[0004] There are still certain disadvantages in use. The conveying liquid enters from the outside of the primary filter cartridge, and impurities are filtered on the outer surface of the primary filter cartridge, which can easily accelerate the clogging of the primary filter cartridge. When cleaning, the impurities accumulated on the outside of the primary filter cartridge are easily passed through the T-type pipe with the conveying liquid, which makes it inconvenient to clean the impurities filtered by it. In addition, the secondary filter cartridge is directly pressed and fixed by the cover plate. When the liquid flows, the flange and cover plate at the upper end of the T-type pipe are subjected to a large impact force, resulting in a reduced service life of the T-type pipe. Utility Model Content

[0005] In order to overcome the above-mentioned technical problems, the utility model aims to provide a T-type pipe filter, which guides the liquid into the interior of the No. 1 filter cartridge through a guide cover, and at the same time, the No. 1 filter cartridge performs auxiliary filtration on the liquid, so that a small part of the liquid passes through the No. 1 filter cartridge, and most of the liquid flushes the No. 1 filter cartridge, and brings the impurities on its surface into the guide tube, and is discharged to the interior of the No. 2 filter cartridge under the guidance of the guide tube. The liquid enters between multiple conical guide plates in layers, and the protrusions facilitate the adhesion of impurities to the surface of the conical guide plates, so that the conveying liquid can enter from the inside of the No. 2 filter cartridge, gather the impurities on the inside of the No. 2 filter cartridge, and collect the filtered impurities in a unified manner, thereby reducing the clogging speed of the No. 2 filter cartridge. At the same time, when cleaning, it is convenient to quickly discharge the impurities accumulated inside the No. 2 filter cartridge to prevent the impurities from passing through the T-tube with the conveying liquid.
