Description

Technical Field

[0001] The utility model relates to a biofuel filtering device and belongs to the technical field of biofuel. Background Art

[0002] Biofuel generally refers to solid, liquid or gaseous fuels composed of or converted from organisms. It is an important direction for the development and utilization of renewable energy. It has good storability and transportability, and can provide liquid fuel that can replace petroleum. Biofuel in a narrow sense refers only to liquid biofuel, mainly including fuel ethanol, biodiesel and aviation biofuel.

[0003] The existing patent number is CN117531269A, which is a filtering device for biodiesel blended fuel. This device divides the interior of the filter box into a filtering area and an impurity discharge area by means of a partition plate. During the process of filtering the blended fuel through the filter box, the position on the inner side of the partition plate can be continuously driven by the material taking hopper, so that the material taking hopper can take the impurities that are continuously accumulated at the inner side of the partition plate and discharge and dump them to the outside of the filter box, thereby being able to discharge the impurities inside the filter device to the outside without pausing the device, thereby improving the working efficiency of the overall device for filtering the blended fuel. However, when this device is in use, the material taking hopper used cannot fit with the bottom of the filter box due to the presence of a filter push plate, making it difficult to completely remove the impurities, and some impurities are easily accumulated in the filter holes, making it difficult to achieve a continuous filtering effect. The push of the filter push plate will push most of the impurities to the left end, while the position of the material taking hopper is fixed, thereby affecting the filtering effect.
