specific Embodiment 1

[0024] Such as figure 1 As shown, the filter includes a housing 1, a filter paper 2, a central tube 3, an upper end cover, a lower end cover 4, an elastic support piece 5, and a water storage cup 6, wherein the filter paper 2, the central tube 3, and the upper and lower end covers constitute a filter element, Water storage cup 6 is installed in the filter element bottom by thread. The elastic supporting piece 5 is arranged at the lower part of the lower end cover 4, and the center of the elastic supporting piece 5 is punched and formed with a central hole 18, and the edge of the central hole 18 protrudes upwards, and is buckled with the circular recess 17 in the center of the lower end cover 4 to fix the filter element. effect.

[0025] In the above-mentioned filter, only the upper and lower end caps of the filter element can be in contact with the diesel on the inner and outer sides of the filter paper 2, and the heat emitted can be directly transferred to the diesel. Howev...

specific Embodiment 2

[0029] A diesel filter, comprising a filter paper 2 and a heating device, the heating device has the same structure as the diesel filter heating device in the above specific embodiment 1.

[0030] The present invention compares with prior art experiment as follows:

[0031] The initial oil temperature is -2°C, the ambient temperature is 0°C, and under the condition of full volume, group A adopts the heating device of the present invention, group B adopts the electric heating tube heating device in the prior art, and the two groups are heated at the same time for 8 minutes. The temperature monitoring results inside the filter are shown in the table below:

[0032]

[0033] It can be seen that the present invention can simultaneously heat the diesel oil on the inner and outer sides of the filter paper, the temperature of the inner and outer sides is increased synchronously, and the heating efficiency is high.

Abstract

The invention relates to a device on a liquid fuel purification device, in particular to a diesel filter and a heating device thereof. The diesel filter comprises filter paper and the heating device. The heating device comprises a lower end cover at the lower portion of the filter paper of the filter. The heating device comprises a magnetic core and a magnetic exciting coil. The magnetic exciting coil is wound around the magnetic core. A magnetic core middle column is closely attached to the lower end cover. The magnetic exciting coil is connected with a circuit board. The circuit board is connected with a direct current power source. The structure of the filter is utilized, diesel oil at the inner end and the outer end of the filter paper is heated at the same time, the heating efficiency is high, and the temperature rise speed is high. The problems that filter paper in a filter of a heavy load truck is blocked by wax due to the over low temperature in winter, consequently, starting is difficulty, and oil supply is not smooth are solved.

Description

technical field [0001] The invention relates to a heating device on a liquid fuel purification device, in particular to a diesel filter and a heating device thereof. Background technique [0002] At present, my country's heavy-duty trucks, engineering vehicles, ships and other equipment usually use diesel fuel as fuel. Because diesel oil contains moisture and other impurities, before entering the engine, diesel must be filtered to remove the moisture and impurities contained in it. The oil-water separator model PL-420 is the most commonly used diesel filter. Its structure mainly includes a shell, a filter paper, a central tube, upper and lower end covers at both ends of the filter paper, elastic support pieces and a water storage cup at the bottom of the structure. This type of filter can effectively filter out harmful impurities and moisture in the fuel system. However, when the temperature is low in winter, the filter paper in the filter is easily blocked by the precipita...
