Abstract

The invention relates to a double worm oil press capable of preventing oil materials from sliding out of a chamber, comprising a frame base, a driving motor, a reduction gear, a torque distributor, a feeding base, a feeding device, a double worm oil pressing device and a residual cake discharging mechanism, wherein the driving motor and the reduction gear are connected to the frame base; the torque distributor is connected to the output end of the reduction gear; the feeding base is connected to the output end of the torque distributor; the feeding device is arranged on the feeding base; the double worm oil pressing device is connected to the feeding base; the residual cake discharging mechanism is positioned on the tail end of the double worm oil pressing device; the feeding base comprises a first material sending hole and a second material sending hole and a first mandrel and a second mandrel; the first and second mandrels are respectively sleeved with a first left spiral worm and a first right spiral worm and respectively positioned in the first material sending hole and the second material sending hole; and a plurality of slide-proof grooves are arranged on the inner walls of the first and second material sending holes in the direction of a generatrix. The double worm oil press disclosed by the invention solves the problem that the oil material may slide out of the chamber, improves the sealing property of the feeding end of the first pressing chamber, effectively prevents the oil material from flowing out of the double worm oil pressing device and has the advantages of high oil yield and high production efficiency.

Description

technical field [0001] The invention relates to a device for pressing oil from oil-containing plants, in particular to a double-screw oil press machine which prevents the smooth bore of oil plants. Background technique [0002] Over the past ten years, vegetable oil has been dehulled (hulled) at room temperature or at low temperature or cold pressed, which has become a major trend in the advancement of oil production technology. As a result, double-screw and triple-screw oil presses have come out one after another. Especially when using a double-screw oil press to press rapeseed peeling and cold pressing, camellia seed shelling and cold pressing, peanut kernel low-temperature pressing and sunflower kernel hot pressing, compared with a single-screw oil press, the residual oil of dry cakes will be reduced. The rate is reduced, the oil yield is increased, and it shows a relatively good pressing process performance and pressing effect. [0003] However, after peeling (shell), t...

AI Technical Summary

Problems solved by technology

[0003] However, after peeling (shell), the physical properties of oil plants change greatly, the crude fiber material is greatly reduced, or even completely eliminated, the oil content is significantly increased, the texture becomes softer, the plasticity increases, the fluidity is better, and the deformation resistance decreases. The friction factor with components such as pressing snails is greatly reduced, so the oil after peeling (shell) is difficult to convey and squeeze in the feeding base and pressing chamber

[0004] The inventor of the present invention has studied and manufactured double-screw oil presses for many years, and analyzed the force, flow and pressure distribution of the oil in the press chamber. Under the conditions of cold pressing or low-temperature pressing, it is necessary to achieve the process effect of high oil yield and low dry cake residual oil rate. On the one hand, it is extremely difficult to use the traditional single-screw oil press. Oil smoothbore failures occur from time to time and are difficult to achieve; on the other hand, the current production and use of double-screw and triple-screw oil presses have the following deficiencies in their technical solutions: 1. The oil press smoothbore always occurs in the feeding Inside the pressing chamber of the base part; 2. A washer-type retaining ring is set at the starting end of the first section of the left-handed pressing screw and the first section of the right-handed pressing screw to form a material-stopping mechanism. The gap between the space and the radial direction between the two retaining rings is large, and the effect of blocking the channeling of oil is lost, and the oil is still easy to channel to the outside of the feeding base

The dehulled rapeseed kernel test was carried out on a single screw oil press. When the hole wall of the feeding hole in the feeding base is smooth, the oil has a serious smoothbore phenomenon, and the oil press cannot even squeeze out the oil.
