Description

Technical Field

[0001] This utility model relates to the field of heavy oil filters, and more particularly to a filter element that is not easily clogged. Background Technology

[0002] The main function of a heavy oil combustion filter is to remove impurities from fuel and protect combustion equipment. The main functions of a heavy oil combustion filter include: removing impurities from fuel: Heavy oil combustion filters can remove solid impurities such as iron oxide and dust from fuel, preventing clogging of the fuel system, especially the fuel injectors. Protecting equipment: By removing impurities, it reduces mechanical wear, ensures stable engine operation, and improves equipment reliability and service life. A filter element is a device used to filter impurities and particles from liquids or gases, and is widely used in various industrial and household appliances. The main function of a filter element is to remove impurities from fluids, protect downstream equipment, or improve the purity of the fluid. Filter elements are generally installed in filters, but existing filter elements installed in heavy oil filters typically have only one filter port, a small filtration area, low filtration efficiency, and are prone to clogging.

[0003] Therefore, it is necessary to design a filter element that is not easily clogged. Utility Model Content

[0004] To address the technical deficiencies in the background technology, this utility model proposes a filter element that is not easily clogged, solving the aforementioned technical problems and meeting practical needs. The specific technical solution is as follows:

[0005] A filter element that is not easily clogged includes a connector, a filter element, and a filter screen. One end of the connector is externally connected to an oil inlet nozzle, and the other end is fixedly connected to the filter element. The filter screen is disposed on the outer surface of the filter element and is fixedly connected to the connector. An input block is disposed at the other end of the filter element away from the connector. Several oil inlets are disposed on the outer side of the input block and cooperate with the filter screen. An oil outlet is disposed in the middle of the connector. The middle part of the filter element is hollow and communicates with the oil outlet. Several filter input ports communicating with the oil outlet are disposed on the outer side of the filter element.

[0006] Furthermore, the inner side of the connector is provided with threads, and the connector is connected to an oil nozzle via the threads.

[0007] Furthermore, the middle part of the filter element is provided with a first annular groove and a second annular groove, and a plurality of filter inlets are evenly distributed in the first annular groove and the second annular groove.

[0008] Furthermore, the number of the plurality of filter input ports is eight, wherein four of the filter input ports are located in the first annular groove and the other four filter input ports are located in the second annular groove.

[0009] Furthermore, the radius of the input block is larger than the radius of the filter element.

[0010] Compared with the prior art, the filter element that is not easily clogged provided by this utility model has the following beneficial effects:

[0011] This utility model discloses a filter element that is not prone to clogging. It is equipped with multiple filter inlets for outputting heavy oil filtered by the filter screen. The filter inlets are divided into two layers, which can lengthen the filter screen, increase the filtration area, and improve the output efficiency. Multiple filter inlets can prevent the heavy oil from being unable to be filtered if one of them is blocked. The multiple oil inlets set in the input block can make the heavy oil start filtering simultaneously from several aspects of the filter screen, avoiding filtration at the same position of the filter screen and preventing premature clogging due to too much filter residue.

One end of the connector 1 is externally connected to an oil nozzle, and the other end is fixedly connected to the filter element 2. After installation, the connector 1 can output filtered heavy oil to the oil nozzle. The filter element 2 is used to input heavy oil into the connector 1. The filter screen 3 is disposed on the outer surface of the filter element 2 and fixedly connected to the connector 1. The filter screen 3 is used to filter the heavy oil. An input block 4 is provided at the other end of the filter element 2 away from the connector 1. The input block 4 is used to input the heavy oil to be filtered. Several oil inlets 5 are provided on the outer side of the input block 4 and cooperate with the filter screen 3.
