Description

Technical Field

[0001] The utility model relates to the technical field of rapeseed oil processing equipment, in particular to a rapeseed oil sludge scraping device. Background Art

[0002] After rapeseed oil flows out of a screw oil press, the oil contains a large amount of impurities including oil sludge and plant fibers. Therefore, it is necessary to filter the rapeseed oil. At present, a filter basket is generally used to filter rapeseed oil. The filter basket is generally a structure in which a filter screen is fixed to the bottom of a square or circular annular frame, and the filter screen covers the bottom opening of the annular frame, and the rapeseed oil will be filtered after passing through the filter screen.

[0003] It is not difficult to see that when the existing filter basket is in use, the filter screen is prone to being blocked by filter residues; and after filtration, the filter residues are generally directly poured out, which causes the rapeseed oil remaining in the filter residues to be wasted, resulting in a certain amount of resource waste. Content of the Utility Model

[0004] The technical problem to be solved by the utility model is to overcome the above technical difficulties and provide a rapeseed oil sludge scraping device which is not prone to blockage during use, and after filtration, the rapeseed oil remaining in the filter residues can be effectively recycled further.

[0005] To solve the above technical problem, the technical solution provided by the utility model is as follows:

[0006] A rapeseed oil sludge scraping device, comprising:

[0007] An oil filter tank, which is an open-top tank structure and is provided with an oil outlet at the bottom;

[0008] An oil filter basket and a rotation driving mechanism; the oil filter basket is an open-top cylindrical structure, and after being rotatably arranged inside the oil filter tank, it is driven by the rotation driving mechanism installed and fixed on the oil filter tank to rotate at a low speed or a high speed;

[0009] An oil sludge scraping structure, which is detachably installed on the oil filter tank and is used for scraping the oil sludge and filter residues on the inner wall of the oil filter basket.

[0010] As an improvement, the oil filter basket includes a mesh basket and a mounting end ring; the mounting end ring is a circular ring structure with an inverted U-shaped cross-section on one side, and the top of the mesh basket is sleeved and fixed on the inner wall of the mounting end ring. A circular guide rail groove is fixed on the inner wall of the top of the oil filter tank. The circular guide rail groove is a circular ring structure with a U-shaped cross-section on one side, and a plurality of guide rollers are rotatably connected between the two side walls. The guide rollers are evenly arranged along the circumference of the circular guide rail groove; the outer side wall of the mounting end ring is movably sleeved inside the circular guide rail groove, and the bottom surface of the outer side wall is movably connected to each guide roller. The rotation driving mechanism includes a motor, a gear and a gear ring; a gear ring is fixed on the top of the mounting end ring, the motor is installed and fixed on the outer wall of the oil filter tank, and a gear is installed and fixed on the output shaft. The gear is located outside the gear ring and meshes with the gear ring. It is used to drive the mesh basket to rotate at a low speed or a high speed.

[0011] As an improvement, the sludge scraping structure includes a hanging cylinder, a hanging rod and a scraping plate; the hanging rod is a straight rod with a bent rod structure after the top is bent into an inverted U-shaped structure. The top of the hanging cylinder is open and fixed on the outer wall of the oil filter tank. The short vertical section of the hanging rod is inserted and fitted inside the hanging cylinder, and a scraping plate movably connected to the inner wall of the mesh basket is fixed on the long vertical section. The hanging rod does not contact the gear ring. It is used to scrape the oil sludge filter residue on the inner wall of the oil basket.

[0012] The advantages of the present utility model compared with the prior art are as follows:

[0013] 1. When the present model is in use, the rapeseed oil flowing out of the screw press is filtered after passing through the mesh basket. At the same time, the motor drives the oil filter basket to rotate at a low speed, and the scraping plate will continuously scrape off most of the oil sludge filter residue attached to the inner wall of the mesh basket, thereby effectively preventing the mesh basket from being blocked.

[0014] 2. After the rapeseed oil filtering work of the present model is completed, the motor is used to drive the oil filter basket to rotate at a high speed. In this way, under the action of centrifugal force, the residual rapeseed oil in the oil sludge filter residue in the mesh basket will be thrown out, so that the residual rapeseed oil in the oil sludge filter residue can be effectively recovered.
