Abstract
Description
Technical Field
[0001] The utility model relates to the field of oil extraction equipment, and particularly relates to an oil extraction equipment with a cleaning component. Background Art
[0002] Oil extraction is generally applicable to various crop seeds. Generally, the extrusion method is used to extract the oil in the crop seeds. Generally, a screw oil press is used to press the seeds to extract oil. The rotating screw shaft advances continuously in the pressing chamber, making the pressed material continuously advance forward. At the same time, due to the shortening of the screw lead or the increase of the root circle diameter of the pressed material, the volume of the pressing chamber space continuously shrinks to generate pressure, compressing the pressed material and squeezing out the oil in the material blank. The oil flows out from the gaps of the pressing cage, and then the residue is pressed into cake blocks by the screw oil press and continuously discharged from the end of the pressing shaft.
[0003] However, when this extrusion method is used, due to its working method of extrusion, some residues will form clots due to pressure and accumulate on the filter screen of the screw oil press, which is difficult to clean. When the accumulation is large, it will also affect the use of the screw oil press.
[0004] Therefore, it is very necessary to propose an oil extraction equipment with a cleaning component to solve the above problems. Content of the Utility Model

Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0024] The present invention provides an oil extraction device with a cleaning component as shown in Figure 1 - Figure 6 It includes an extraction frame 1. One end of the extraction frame 1 is fixedly provided with an oil press shell 3. One end of the extraction frame 1 is fixedly provided with a waste box 102. The end of the oil press shell 3 is fixedly connected to the waste box 102. A screw oil press shaft 101 is movably arranged inside the oil press shell 3. The screw oil press shaft 101 is a commonly used oil press component in the prior art and will not be described in detail here. One end of the extraction frame 1 is fixedly provided with a driving motor 2. The driving motor 2 is a servo motor, which is prior art and will not be described in detail here. The output end of the driving motor 2 is fixedly connected to the end of the screw oil press shaft 101. A feed hopper is arranged at the upper end of the extraction frame 1. The feed hopper is mainly used for adding raw materials for oil pressing, which is prior art and will not be described in detail here.
[0025] The operator adds the raw materials into the interior of the extraction frame 1 through the feed hopper, so that the raw materials enter the oil press shell 3. Then, the driving motor 2 is turned on to make the driving motor 2 work, driving the screw oil press shaft 101 to rotate inside the oil press shell 3 to squeeze the raw materials for oil pressing work.
[0026] A plurality of oil outlet holes 4 are opened on the outer side of the oil press shell 3. Reinforcing plate members 5 are fixedly arranged on the outer side of the oil press shell 3. A plurality of arc-shaped grooves are equidistantly opened on the outer side of the reinforcing plate members 5. The oil outlet holes 4 are located in the corresponding arc-shaped grooves. Through the setting of the oil outlet holes 4, when the screw oil press shaft 101 works, the squeezed oil is discharged from the interior of the oil press shell 3 through the oil outlet holes 4, and the residue is input into the inner side of the waste box 102 through the screw oil press shaft 101, facilitating secondary oil pressing;
[0027] A plurality of sealing plates 6 for sealing the oil outlet holes 4 are movably provided on the inner side of the arc groove, a connecting ring 7 is fixedly provided between the sealing plates 6 in the same vertical plane, an extension plate 10 is fixedly provided on the outer side of the connecting ring 7 close to the extraction frame 1, and two electric cylinders 9 are fixedly provided on one end of the extraction frame 1 corresponding to the extension plate 10. The electric cylinder 9 is a prior art and will not be described in detail herein. The output end of the electric cylinder 9 is fixedly connected to one side of the corresponding extension plate 10, a sliding groove 11 is provided on the inner side of the reinforcement plate 5, the connecting ring 7 slides in the sliding groove 11, and two connecting rods 8 are provided in the arc groove, and the connecting rod 8 is fixedly connected to the corresponding sealing plate 6 and the connecting ring 7.
[0028] Two water pipes 15 are provided on one side of the extraction frame 1, and the water pipes 15 are connected to a plurality of high-pressure nozzles 13. The high-pressure nozzles 13 are fixedly connected to the corresponding sealing plates 6. The sealing plates 6 connected to the high-pressure nozzles 13 are located at the uppermost end of the oil pressing shell 3, so that the flushing liquid can flow downstream when flushing the oil pressing shell 3. The liquid raw material used to flush the oil pressing shell 3 is the same crude oil as the oil production oil. The sealing plates 6 are arranged in an arc shape, and the high-pressure nozzles 13 are located at the eccentric part of the sealing plates 6. The outer sides of the two rows of sealing plates 6 are provided with connecting holes 14 for the high-pressure nozzles 13 to communicate with the inside of the oil pressing shell 3.
[0029] When the oil press has finished pressing oil, and the oil outlet hole 4 on the oil press shell 3 is clogged with residue, the operator opens the water pipe 15 and flushes the inside of the oil press shell 3 through the high-pressure nozzle 13. By setting the position of the high-pressure nozzle 13, the inside of the oil press shell 3 can be flushed to the greatest extent, and the inside of the oil press shell 3 can be automatically flushed to flush the oil outlet hole 4, so as to prevent the residue from accumulating in the oil outlet hole and affecting the oil outlet efficiency.
[0030] Through the movable sealing plate 6, targeted cleaning can be performed according to the amount of residue inside the oil pressing shell 3. The extension plate 10 is driven to move by the electric cylinder 9, so that the extension plate 10 drives the connecting ring 7 to move. Under the limit of the sliding groove 11, the connecting ring 7 moves away from the electric cylinder 9, and the connecting ring 7 drives the sealing plate 6 and the connecting rod 8 to move, so that the sealing plate 6 drives the high-pressure nozzle 13 to contact the oil outlet 4. The operator controls whether the sealing plate 6 completely blocks the oil outlet 4 according to the amount of residue left in the oil pressing shell 3.
[0031] When there are a lot of residues inside the oil pressing shell 3, in order to prevent the residues from entering the extruded oil, the oil outlet hole 4 is completely closed, so that the residues are flushed into the waste box 102 to prevent the previously extruded oil from being dirty. When there are less residues inside the oil pressing shell 3, the oil outlet hole 4 is not completely blocked, and the oil flushed from the oil pressing shell 3 is recovered.
