Description

Technical Field

[0001] This utility model relates to the technical field of diesel filtration, and more specifically, to a filter element for biodiesel. Background Technology

[0002] Diesel filters are an essential component for diesel engines. Biodiesel refers to fatty acid methyl esters or ethyl esters formed by converting vegetable oil, animal oil, waste oil, or microbial oil with methanol or ethanol. However, impurities inevitably mix into biodiesel during the production process. To reduce the wear of impurities on the diesel engine, a diesel filter is required.

[0003] Most existing diesel fuel filters are one-piece structures, meaning that the impurities filtered out by the filter are directly retained inside. When there are many impurities in the filter, the entire filter must be replaced, which increases the cost of using the filter. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a filter element for biodiesel, which can be disassembled separately by means of a disassembly cover and filter tube, so as to facilitate cleaning or replacement and reduce the use cost of the filter element.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a filter element for biodiesel, comprising a housing, wherein the top of the housing is open, and an oil inlet pipe and an oil outlet pipe are fixedly connected to the outside of the housing;

[0006] A separator ring is fixedly connected to the inner wall of the housing and divides the housing into an oil inlet chamber located at the top of the separator ring and an oil outlet chamber located at the bottom of the separator ring. The oil inlet pipe is connected to the oil inlet chamber and the oil outlet pipe is connected to the oil outlet chamber.

[0007] A filter tube for filtering diesel fuel passing through its wall, the filter tube being closed at the bottom and open at the top, the filter tube passing through a separator ring and fitting against the inner wall of the separator ring.

[0010] The present invention is further configured such that: the top of the separator ring is provided with an annular groove, and the bottom of the pressure ring is fixedly connected with a sealing ring that cooperates with the annular groove.

[0011] The present invention is further configured such that: the connecting pipe has a plurality of connecting holes that penetrate the side wall of the connecting pipe.

[0012] The present invention is further configured such that: the filter tube support frame is fixedly connected to the bottom of the connecting pipe and is arranged in a tubular shape;

[0013] And a filter membrane, which is attached and fixed to the inside of the support frame.

[0014] The present invention is further configured such that: two sealing rings are fixedly connected to the bottom of the disassembly cover, and the sealing rings are configured as elastic sealing rings. When the disassembly cover is pressed against the top of the connecting tube, the two sealing rings are respectively attached to the inner and outer sides of the connecting tube.

[0015] The present invention is further configured such that: a rubber ring is fixedly connected to the bottom of the disassembly cover, and when the disassembly cover is pressed against the top of the housing, the rubber ring adheres to the inner wall of the housing.

[0016] The present invention is further configured such that the detachable cover is detachably connected to the top of the housing via two connecting components;

[0017] The connecting component includes a connecting block, which is fixedly connected to the outside of the disassembly cover;

[0018] A fixing block, which is fixedly connected to the outside of the housing and located below the connecting block;

[0019] A connecting rod is fixedly connected to the top of the fixing block and is vertically arranged, with the connecting rod passing vertically through the connecting block;

[0020] And a nut, which is detachably connected to the connecting rod and can be pressed against the top of the connecting block.

[0021] In summary, the present invention has the following advantages over the prior art: the present invention, through the design of the disassembly cover and the filter tube, allows the filter tube to be disassembled separately, thereby facilitating cleaning or replacement and reducing the cost of using the filter element.
