Description

Lifting device for spiral oil press

Technical Field

The invention belongs to the technical field of screw oil presses, and particularly relates to a lifting device for a screw oil press.

Background

An oil press is a machine that presses oil from oil by increasing the temperature to activate oil molecules by the action of a mechanical external force. Can be divided into a household oil press, a hydraulic press oil press, a screw oil press, a novel hydraulic oil press, a high-efficiency fine filtration oil press and a full-automatic oil press. When the oil press is operated, the processed raw materials enter the barrel from the hopper. Because the material blank is carried out in the barrel of the oil press in a moving state, under the condition of high pressure of the barrel, great frictional resistance is generated between the material blank and the pressing screw, and between the material blank and the barrel; the heat generated by friction meets the heat required by the operation of the oil pressing process, is helpful for promoting the thermal denaturation of protein in the material embryo, and finally the oil in the raw material is pressed out.

After the screw oil press extracts oil, a specific device is needed to extract oil in an oil storage tank on the screw oil press and carry out uniform refining processing, and a lifting device of the oil is used in the process. However, most of the existing lifting devices can not filter out the peanut skin (or the skins of soybean, corn and the like) in the oil, so that the quality of the oil is not high enough; meanwhile, the oil produced by the screw oil press contains solid particles of peanut (or soybean, corn) and other raw materials, so that the purity of the oil is not high enough.

Chinese patent document CN204161986U discloses a lifting device for screw oil press, which includes a motor base, a flange, a discharge hopper, a feed hopper, a frame and so on, wherein a main body of the frame is provided with a base shaft, the base shaft is provided with a positive helical blade, a reverse helical blade and a retainer ring, the setting of the positive helical blade and the reverse helical blade changes the traditional extrusion discharging mode, the retainer ring is provided to prevent oil from entering a transmission mechanism, but no relevant means is provided to prevent the raw material particles from entering the oil and thereby improving the purity of the oil.

Chinese patent CN101531069A describes such a frequency-modulation speed-regulation multi-ring oil press, which comprises a press body, a gearbox and an electric control box, wherein the press body, the gearbox and the electric control box are mounted on the press body, the gearbox is connected with a motor through a belt, and one end of a press shaft penetrates out of a press chamber and is connected with an output end of the gearbox. After the power supply of the whole machine is turned on, oil enters the barrel through the blanking hopper, and the oil is pushed to the slag outlet from the feeding port by the pressing screw under the driving of the gearbox. In the scheme, the gearbox is still actually formed by a group of reduction gears, the gears of the gearbox are directly connected with the squeezing shaft to drive the squeezing shaft to rotate, the pressure in the squeezing chamber is increased through the check ring, and the temperature of the oil residue is increased under the heating action of the heating plate, so that the oil yield is improved. Because the oil press is directly connected with the press shaft, the gear loss of the gearbox is large, and because the internal pressure of the press barrel is obviously reduced after the speed is reduced by the gearbox, the oil yield is greatly influenced.

Chinese patent CN102039689A discloses a continuous low-temperature oil press, which is provided with a first speed regulating motor, a second speed regulating motor and a third speed regulating motor respectively connected with a screw rod, so as to regulate the rotation speed of the screw rod. Although the rotating speed of the screw can be automatically adjusted to the required speed, the technical scheme has a complex structure, needs to add too many control circuits and has quite large fire hazard.

Chinese patent CN103085307A discloses a kitchen waste squeezing machine, which is connected with a screw shaft through a gear box and a coupling, wherein the gear box actually functions as a reduction box, i.e. the rotational speed of a motor is reduced and then transmitted to the screw shaft. If the screw shaft of the squeezer rotates at a high speed, not only can shearing force be easily generated on the gearbox to greatly damage the gearbox, but also a larger torque is generated under the condition of idle rotation, so that serious shaking can be generated to aggravate the abrasion of the screw shaft, therefore, the squeezer can only run at a constant speed at a low speed, and the squeezing effect is greatly reduced.

Chinese patent CN103317744A discloses a household oil press, which comprises a motor, a speed changing device, a motor bottom plate, a connecting sleeve, a barrel, a pressing screw, etc., wherein the speed changing device is directly connected with the pressing screw 6, a baffle at the rear part of the pressing screw contacts with a plane bearing, so that the backward thrust generated by the screw when the oil press works can be released to the plane direction on the bottom plate through the rotation motion of the plane bearing, thereby avoiding the deformation of the steel bottom plate, the gearbox shell and the gear top in the gearbox caused by long-time single-point support, and further preventing the service life of the product from being affected by the force; the hollow structure of the feed port is improved, the slope which is the same as the rotation direction of the screw rod during working is arranged at the feed port of the squeezer, the raw materials to be crushed can be directly guided to the feeding area, the materials are prevented from being stacked and blocked, the crushing and squeezing working area of the materials can be enlarged, the oil yield and the oil output are improved, the same effect as that of the structure is achieved only when the squeezing part is prolonged by 15mm through testing, and the weight of the squeezer is increased by 150 g, so that the raw materials can be saved, and the production cost is reduced; the boring hole of the feeding part is eccentrically arranged towards the front part of the feeding hole in the rotating direction of the screw rod during working, so that materials can enter the boring hole along with the pressing screw rod; the long-strip shallow grooves on the outer wall of the squeezing part can increase friction, and are convenient to screw down or screw down when being disassembled, washed or maintained; the pressing part polygonal hole boring can increase the extrusion force and the friction force during working, and the crushing effect is improved.

There is a need in the art for a lifting device for a screw oil press that can mechanically increase the purity of oil.
