All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to the attached drawings 1-3 and 6-7 of the specification, the rapeseed oil sedimentation tank of the embodiment comprises a sedimentation tank body 1, wherein a pure oil discharge pipe 11 is arranged on one side of the top of the sedimentation tank body 1, and an impurity outlet 12 is arranged on the other side of the bottom of the sedimentation tank body, a filtering inner cylinder 4 is fixedly arranged on the top of an inner cavity of the sedimentation tank body 1 through a support, a feed pipe 5 is arranged on the top of the filtering inner cylinder 4, a discharge hole 6 is arranged at the bottom of the filtering inner cylinder 4, a primary filtering mechanism 2 is arranged in the filtering inner cylinder 4, the impurity outlet 12 is connected with a spiral feeding machine 8, and the outlet end of the spiral feeding machine 8 is connected with a secondary filtering and recovering mechanism 3;

The implementation scenario is specifically as follows: when the rapeseed oil filter is used, squeezed rapeseed oil enters the interior of the filter inner barrel 4 through the feeding pipe 5, multi-layer filtration is carried out by the filter assembly 21, the filtered rapeseed oil enters the sedimentation tank body 1 from the discharge hole 6 at the bottom, sedimentation continues in the sedimentation tank body 1, finally, the pure rapeseed oil is discharged through a pump body drawing on the pure oil discharge pipe 11 without work labeling, and precipitated impurities are discharged from the impurity outlet 12;

an electromagnetic valve can be arranged at the inlet of the screw conveyer, when precipitated impurities are discharged, the electromagnetic valve and the screw conveyer are opened, the screw feeder 8 spirally conveys and feeds the impurities to the secondary filtering and recycling mechanism 3, the impurities fall onto the discharging filtering paddle 33 in the filtering box 31, the motor drives the plurality of rollers 32 to rotate through a gear chain, namely, a plurality of groups of discharging filtering paddles 33 are driven to rotate, the discharging filtering paddles 33 arranged outside two adjacent rollers 32 are attached to each other, when the discharging filtering paddle 33 at one end receives the impurities and rotates to convey the impurities, the impurities conveyed to the right side fall onto the discharging filtering paddle 33 outside the second roller 32, so on, when the plurality of rollers 32 rotate simultaneously, the precipitated impurities are conveyed rightwards, and in the conveying process, because the discharging filtering paddle 33 is composed of a second filtering cloth and a second frame, therefore, in the process of rotationally conveying the impurities, the filtration is realized again, the filtered rapeseed oil falls into the filter box 31 and flows into one side of the return pipe 35 from the inclined bottom surface of the inner cavity of the filter box, the return pipe 35 can be provided with a return pressure pump, the rapeseed oil flows back to the blanking pipe after working and enters the filter inner cylinder 4 for the circulation filtration and the precipitation again, so the rapeseed oil in the filter box 31 is separated from the impurities again, in which impurities may be present, impure, and which, due to the transport of the impurities by the blanking filter blades 33, impurities may be scattered, so that the rapeseed oil after being filtered flows back to be filtered and precipitated again, the discharged impurities are ensured to contain less rapeseed oil, after the whole device is used, the rapeseed oil has better filtering effect, the purification rate of the rapeseed oil is greatly improved, and the rapeseed oil cannot be wasted.

Referring to the attached figure 2 of the specification, a filter screen 7 is fixedly arranged inside the sedimentation tank body 1, and the filter screen 7 is annular and fixedly connected with the inner side wall of the filter inner cylinder 4.

The implementation scenario is specifically as follows: according to the invention, the filter screen 7 is arranged on the discharge hole 6 at the bottom of the filter inner barrel 4, so that the rapeseed oil containing impurities discharged from the discharge hole 6 is prevented from being extracted by the pure oil discharge pipe 11, and the extracted rapeseed oil is ensured to be pure rapeseed oil.

Referring to the attached drawings 4-5 in the specification, the filter assembly 21 is conical, the filter assembly 21 includes a first filter cloth and a first frame, and the first frame is two and is respectively and fixedly arranged at the top and the bottom of the first filter cloth.

The implementation scenario is specifically as follows: when the primary filtering mechanism 2 performs filtering work, the rapeseed oil is firstly filtered by the conical filtering component 21, and then enters the next layer of filtering component 21 for filtering, so that the filtered rapeseed oil is discharged into the sedimentation tank body 1 after being filtered by multiple layers, when the liquid level of the discharged rapeseed oil rises above the discharge port 6, impurities are continuously precipitated, the rapeseed oil with the impurities discharged from the filtering inner cylinder 4 is concentrated below the filtering inner cylinder 4, when the liquid level continues to rise, the impurities in the rapeseed oil below the filtering inner cylinder 4 are continuously precipitated, the rapeseed oil outside the filtering inner cylinder 4 is relatively pure, and the rapeseed oil can be directly discharged;

after filtering a period of time, servo motor drives the chain gear group and carries out work, the chain gear group drives pivot 22 and scraper blade 24 and rotates, scraper blade 24 can scrape filterable impurity on the filter cloth get, rotatory a week back, constantly get into the rapeseed oil that filters inner tube 4 and can erode it, arrange to the sedimentation tank body 1 of filtering inner tube 4 below from discharge gate 6, and because concentrated impurity is heavier, it can quick deposit, clear up filtering component 21 through scraper blade 24, not only can be convenient for the quick filtration work in later stage, and the concentrated impurity drops and can accelerate the deposit after the clearance, whole device is through filtering and scraping the setting of getting impurity, can accelerate the deposit of impurity in the rapeseed oil, also can obtain pure rapeseed oil.

Although the invention has been described in detail above with reference to a general description and specific examples, it will be apparent to one skilled in the art that modifications or improvements may be made thereto based on the invention. Accordingly, such modifications and improvements are intended to be within the scope of the invention as claimed.
