Description

Technical Field

[0001] The utility model belongs to the technical field of oil pressing equipment, and more specifically, particularly relates to a self-cleaning screw oil press. Background Art

[0002] Oil pressing equipment refers to mechanical equipment used to extract edible oil from various oil crops. This type of equipment separates oil from raw materials by physically squeezing the oil or extracting it with chemical solvents. Oil pressing equipment is widely used in households, small processing workshops and large-scale commercial production.

[0003] Most of the current oil pressing equipment uses a spiral conveying shaft to apply extrusion force to oil crops to extract oil. For example, a spiral oil pressing equipment with an oil residue scraping mechanism with application number CN201921810490.6 includes a support base and an oil pressing cylinder installed on the support base. The upper end of the oil pressing cylinder is provided with a feed inlet, and the lower end is provided with an oil outlet sieve hole. A central rotating shaft and spiral blades are installed in the oil pressing cylinder, and the central rotating shaft is connected to the motor transmission. It is characterized in that an oil residue scraping mechanism is arranged outside the barrel wall of the oil pressing cylinder, and the oil residue scraping mechanism includes a rotating ring coaxially movably sleeved on the outer wall of the oil pressing cylinder. A driving wheel is installed on the support seat, and the rotating ring is drivingly connected to the driving wheel; a scraper rod is installed on the rotating ring, and an arc-shaped scraper is installed on the scraper rod, and the outer edge of the blade of the arc-shaped scraper is in contact with and parallel to the outer cylinder wall of the oil pressing cylinder at the oil outlet screen hole. Although the equipment effectively prevents impurity groups from clogging the oil outlet screen hole and ensures the smoothness of the oil out of the screen hole, thereby maintaining a high oil outlet speed, the equipment lacks a self-cleaning structure for the oil pressing structure. Therefore, it is not convenient to clean the inside of the equipment after use, resulting in mildew of the internal residue and breeding of bacteria, thereby affecting the quality of the next oil pressing.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a self-cleaning screw oil press is provided to achieve a more practical purpose. Utility Model Content
