Anti-block oil expression method of oil press

Abstract

The invention discloses an anti-block oil expression method of an oil press. The anti-block oil expression method comprises the following steps: 1, a motor drives a screw rod to rotate forwards relative to a barrel to realize oil expression, the real-time parameter a of the motor or / and the screw rod is compared with a preset value b, and the step 1 is carried out again if a is smaller than b, or the step 2 is carried out if a is equal to or larger than b; step 2, the motor stops rotating for a preset time t to ensure that oil of an expressed material is discharged sufficiently; step 3, the motor rotates backwards to ensure that the barrel is lubricated with the oil, and the motor rotates forwards to carry out the step 1 again after lubrication. The anti-block oil expression method comprises the following steps: when the oil press is blocked, the motor stops rotating for the preset time t to ensure that the oil of the expressed material is discharged sufficiently, and then the motor rotates backwards to ensure that on one hand the barrel is lubricated with the oil, on the other hand the motor is released; finally, the motor rotates forwards to continue oil expression. As blockage is solved in both aspects of friction force reducing and releasing, the anti-block effect is good, the oil expression speed is accelerated, the oil expression efficiency is improved, the energy consumption is reduced, and the service life of the oil press is prolonged.

Description

technical field [0001] The invention relates to an anti-clogging oil extraction method for an oil press. Background technique [0002] With the rapid development of social economy, people's requirements for living standards are getting higher and higher. There is an oil press on the market, such as the 201410179343.9 disclosed in the Chinese patent database. It includes a main part, a driving part, a pressing chamber, a screw , plugs, heaters, oil containers, racks and funnels. The main body part has a bottom, a first support part and a second support part, the first support part and the second support part are located above the bottom along the first direction at intervals, and the first support part is provided with a hole penetrating along the first direction Support holes. The driving part is installed in the second supporting part. The press chamber bridges the second support portion and the support hole, and the press chamber is provided with a hollow hole, a plural...

AI Technical Summary

Problems solved by technology

[0003] It is found through experiments that the oil press is very prone to stalling at the beginning of pressing, because the oil is very dry at the beginning of pressing, and the pressure and natural friction resistance are very large, which will cause the screw to be tightly held

[0004] For the above-mentioned deficiencies, someone has proposed a solution, such as CN203788196U, CN203745833U, CN204322587U. When a blockage occurs, the motor reverses to loosen the grip, and then rotates forward again after the reverse. Although it can alleviate the blockage to a certain extent, due to When blockage occurs, it is directly reversed. At this time, the squeezed material has not completely released oil, and the oil does not play a lubricating role when reversed. Therefore, it is necessary to further improve the anti-blocking effect.
