[0025] In the description of the present utility model, "greater than", "less than", "exceed" etc. are understood as not including the number itself, and "above", "below", "within" etc. are understood as including the number itself. If there is a description of "first" or "second", it is only used for the purpose of distinguishing technical features, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.

[0026] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0027] See also Figure 1-5 The utility model provides a technical solution: a water-absorbing filter element for biodiesel, comprising a filter element housing 3, an oil inlet pipe 2 is adhered to the surface of the filter element housing 3, and a filtering device with a self-cleaning function is arranged inside the filter element housing 3;

[0028] Among them, the filtering device includes a second water-absorbing layer 5, the surface of the second water-absorbing layer 5 is adhered to the bottom of the filter element housing 3, a filter screen 7 is welded inside the filter element housing 3, a frame 6 is installed on the surface of the filter screen 7, and four cleaning frames 8 are welded on the surface of the frame 6.

[0029] The motor 1 is screwed onto the upper surface of the filter element housing 3 , and the output end of the motor 1 is connected to the surface of the frame 6 .

[0030] A first water absorbing layer 4 is adhered to the inside of the filter element housing 3 , and the oil inlet pipe 2 is located between the outer surface of the first water absorbing layer 4 and the inner wall of the filter element housing 3 .

[0031] An oil outlet hole 10 is provided at the bottom of the filter housing 3;

[0032] An oil outlet pipe 9 is welded to the lower surface of the filter element housing 3 .

[0033] A through hole 11 is formed on the surface of the filter element housing 3 , and the through hole 11 is located between the inner surface of the second water absorbing layer 5 and the outer surface of the filter screen 7 .

[0034] A dirt storage tube 12 is welded to the lower surface of the filter element housing 3 , and a tube cover 13 is threadedly connected to the outer surface of the dirt storage tube 12 .

[0035] When the water-absorbing filter element is used, first, biodiesel is poured into the gap between the first water-absorbing layer 4 and the filter element housing 3 through the oil inlet pipe 2 to perform preliminary water removal.

[0036] Secondly, the biodiesel passes through the second water absorption layer 5 for secondary water removal.

[0037] Finally, the biodiesel is filtered through the filter screen 7 , passes through the oil outlet hole 10 to the inside of the oil outlet pipe 9 , and leaves the inside of the filter element housing 3 .

[0038] When it is necessary to clean the residue on the surface of the filter 7, the motor 1 is started by an external power supply to drive the frame 6 to rotate, and the rotation of the frame 6 drives the cleaning frame 8 to rotate. The rotation of the cleaning frame 8 drives the residue filtered on the surface of the filter 7 to move downward by its own gravity, and then is carried by the lower end of the cleaning frame 8 to rotate until the residue moves to the position of the through hole 11, and falls into the interior of the scale storage tube 12 by gravity, and finally the tube cover 13 is rotated to take out the residue.

[0039] By setting four cleaning racks 8 that rotate continuously in the filtering device, the residue on the surface of the filter screen 7 is driven to separate from the surface of the filter screen 7, and then move downward to the lower end of the cleaning rack 8 by its own gravity. The lower end of the cleaning rack 8 continues to move to the inside of the scale storage tube 12 with the residue, so as to clean the residue on the surface of the filter screen 7 and collect the residue at the same time, and avoid the phenomenon that the residue keeps floating and falls into the surface of the filter screen 7 again, thereby effectively avoiding the phenomenon that the residue accumulates on the surface of the filter screen 7 and blocks the normal filtering and circulation of biodiesel, thereby ensuring the smoothness of the flow filtration of the biodiesel.

[0040] By providing the first water absorbing layer 4 and the second water absorbing layer 5 for double water absorption, it is avoided that the water content in the biodiesel is too high, thereby effectively improving the purity of the biodiesel.

[0041] Working principle: When the water-absorbing filter element is used, first, the biodiesel is poured into the gap between the first water-absorbing layer 4 and the filter element housing 3 through the oil inlet pipe 2 to perform preliminary water removal.

[0042] Secondly, the biodiesel passes through the second water absorption layer 5 for secondary water removal.

[0043] Finally, the biodiesel is filtered through the filter screen 7 , passes through the oil outlet hole 10 to the inside of the oil outlet pipe 9 , and leaves the inside of the filter element housing 3 .

[0044] When it is necessary to clean the residue on the surface of the filter 7, the motor 1 is started by an external power supply to drive the frame 6 to rotate, and the frame 6 drives the cleaning frame 8 to rotate. The cleaning frame 8 drives the residue filtered on the surface of the filter 7 to move downward by its own gravity, and then is carried by the lower end of the cleaning frame 8 to rotate until the residue moves to the position of the through hole 11, and falls into the interior of the scale storage tube 12 by gravity, and finally the tube cover 13 is rotated to take out the residue.

[0045] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
