Problems solved by technology

[0003] The main function of the gasoline filter is to filter out impurities in gasoline, which is mainly filtered by filter paper. After long-term use of the traditional filter paper, due to the low strength of the filter paper, the pore size of the filter paper will gradually change in actual application. Large, this will cause some impurities to flow into the engine and cause harm. To solve this problem, the current method is to regularly update the steam filter, or replace it with a relatively high-quality filter paper. Although these two methods can solve some problems, but The actual cost is relatively high, so if the strength of filter paper is enhanced, it is a necessary research topic in the current field

Embodiment 1

[0025] A method for increasing the strength of gasoline filter paper, comprising the following preparation steps:

[0026] 1) Install the purchased rolled filter paper on the conveying frame, and then convey it forward through the conveying roller, and install a pressure roller with rough surface wall at the rear end of the conveying roller; it is used to roughen the surface of the filter paper, which is convenient for follow-up water absorption;

[0027] 2) Spray the surface of the filter paper after the rough treatment in step 1 with clear water. When spraying, put the water in the spray tank. It is advisable to spray 25g of water per square meter of filter paper, which is used to wet the surface of the filter paper, which is convenient Subsequent processing;

[0028] 3) After the above-mentioned filter paper is wetted, pass the filter paper through the soaking tank, and add the enhanced treatment liquid in the soaking tube in advance, so that the soaking time of the filter...

Embodiment 2

[0041] A method for increasing the strength of gasoline filter paper, comprising the following preparation steps:

[0042] 1) Install the purchased rolled filter paper on the conveying frame, and then convey it forward through the conveying roller, and install a pressure roller with rough surface wall at the rear end of the conveying roller; it is used to roughen the surface of the filter paper, which is convenient for follow-up water absorption;

[0043] 2) Spray the surface of the filter paper after the rough treatment in step 1 with clear water. When spraying, put the water in a spray tank. The amount of water sprayed per square meter of filter paper is preferably 15g, which is used to wet the surface of the filter paper, which is convenient Subsequent processing;

[0044] 3) After the above-mentioned filter paper is humidified, pass the filter paper through the soaking tank, and add the enhanced treatment liquid in the soaking tube in advance, so that the soaking time of ...

Abstract

The invention discloses a method for improving the strength of filter paper of a fuel filter and relates to the technical field of filter processing. According to the method, the outer wall of the filter paper is roughened, subjected to water treatment, then soaked in enhancement solution, baked and then roughened again. The method has the advantages that technological process is simple; by strengthening the existing filter paper, uniformity of the aperture of the filter paper is guaranteed when the filter paper is used, the strength of the filter paper is improved, the service life of the filter paper is longer, and then consumption of the filter paper is reduced and actual cost is reduced.

Description

technical field [0001] The invention relates to the technical field of filter processing, in particular to a method for increasing the strength of filter paper of a gasoline filter. Background technique [0002] Gasoline filters are referred to as steam filters. Gasoline filters are divided into carburetor type and electric injection type. For gasoline engines using carburetors, the gasoline filter is located on the inlet side of the fuel pump, and the working pressure is relatively small. Nylon casing, the gasoline filter of the EFI engine is located on the outlet side of the fuel pump, and the working pressure is relatively high, so a metal casing is usually used. The filter element of the gasoline filter mostly uses filter paper, and some gasoline filters use nylon cloth and polymer materials. The main function of the gasoline filter is to filter out impurities in gasoline. : Gasoline filter is inside this type of gasoline filter, and the folded filter paper is connected...
