Description

Technical Field

[0001] The utility model relates to the technical field of edible oil production, in particular to a filtering device for edible oil production. Background Art

[0002] In the processing of edible oil, filtration is an important step, mainly used to remove suspended matter, solid particles and other residues to improve the quality and purity of the oil. The existing publication number: CN217838841U discloses an edible oil production filter, which can repeatedly extrude the residues after filtration, so as to help extrude the excess edible oil in the residues, and finally obtain dry residues with very little liquid content, improving the oil yield of edible oil.

[0003] However, when the filter presses the residues with the pressing plate, the pressing plate will block the filter screen, and the filtering work will be interrupted. It is also necessary to clean the filter screen with a brush before continuing to filter the edible oil, resulting in a long intermittent time for the equipment to filter and unable to work continuously, with low work efficiency; moreover, the pressing plate directly applying downward pressure on the filter screen may cause the filter screen to deform, and the residues on the filter screen are also easily pressed into the mesh holes to cause blockage of the filter screen. Although the filter is provided with a brush to clean the filter screen, the brush located above the filter screen may brush off the residues pressed into the mesh holes, resulting in the re-mixing of the residues and the edible oil, affecting the quality of the edible oil. Summary of the Utility Model

[0004] Aiming at the deficiencies of the prior art, the utility model provides a filtering device for edible oil production, which solves the technical problem of the long intermittent time of the existing filtering device.

[0005] To solve the above technical problems, the utility model provides the following technical solutions: A filtering device for edible oil production, including a base, an installation frame is fixedly installed on the back of the base, an oil barrel is installed inside the installation frame, a servo motor is fixedly installed at the center of the top of the base, the output end of the servo motor is fixedly connected with a support rod, the upper end of the support rod is fixedly connected with a bracket, filter barrels are rotatably installed on both sides of the bracket, and a collection barrel and an extrusion box are respectively movably installed on both sides of the top of the base.

[0006] Further, an arc-shaped filter screen is fixedly installed inside the filter barrel, and the arc-shaped filter screen bulges upward.

[0007] Further, an oil guiding disc is fixedly connected to the outer surface of the support rod through a connecting rod, and one end of the oil guiding disc close to the collection barrel is inclined downward.

[0008] Furthermore, both sides of the filtering barrel are fixedly connected with rotating shafts, the rotating shafts are rotatably connected to the inner wall of the bracket, and a torsion spring is sleeved outside the rotating shafts. One end of one of the rotating shafts passes through the bracket and is fixedly connected with a handle.

[0009] Furthermore, a filter screen is slidably installed inside the extrusion box, a slope is arranged on the inner bottom wall of the extrusion box, and an oil outlet pipe is arranged on one side of the extrusion box.

[0010] Furthermore, electric push rods are symmetrically installed outside the extrusion box, and the output ends of the electric push rods extend into the extrusion box and are fixedly connected with pressing plates.

[0011] By means of the above technical solutions, the present utility model provides a filtering device for edible oil production, which at least has the following beneficial effects:

[0012] 1. By arranging two filtering barrels, while one filtering barrel is performing filtering operations, the residue in the other filtering barrel can be poured into the extrusion box to extrude the edible oil in the residue. By controlling the alternating operation of the two filtering barrels, continuous filtering of the edible oil can be achieved, improving work efficiency.

[0013] 2. By arranging two pressing plates, the traditional vertical extrusion force of the filter is optimized into a horizontal extrusion force. During the process of extruding the residue, the filter screen is not stressed, which can prevent the filter screen from deforming and also avoid the residue being pressed into the mesh holes, ensuring the filtering efficiency of the filter screen.

[0014] 3. By arranging an upwardly convex arc-shaped filter screen, compared with the traditional flat filter screen, the surface area of the arc-shaped filter screen is larger, and more edible oil and residue can be processed per unit area, improving the filtering efficiency. The convex design can increase the gap and the space for the edible oil to pass through, effectively reducing the risk of residue blockage. BRIEF DESCRIPTION OF THE DRAWINGS

Specific implementation manners

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0024] When the existing filter presses the residue with the pressing plate, the pressing plate will block the filter screen, and the filtering work will be interrupted. It is also necessary to clean the filter screen with a brush before continuing to filter the edible oil, resulting in a relatively long intermittent time for the equipment to filter and a low working efficiency. Moreover, the pressing plate directly applying a downward pressure on the filter screen may cause the filter screen to deform, and the residue on the filter screen is also easily pressed into the mesh holes to cause blockage of the filter screen. The brush may brush off the residue pressed into the mesh holes, resulting in the residue being remixed with the edible oil and affecting the quality of the edible oil.

[0025] To solve the defects existing in the above-mentioned filtering device during use, please refer to Figures 1-6, a filtering device for edible oil production provided by the utility model can alternately filter edible oil using two filtering barrels 6, realize continuous filtering work, improve work efficiency, and can also collect the filtered residues into the extrusion box 12 for unified extrusion, preventing the residues from mixing with the edible oil again, and optimizing the vertically applied extrusion force of the traditional filter into a horizontally applied extrusion force. During the process of extruding the residues, the filter screen 16 is not stressed, which can prevent the filter screen 16 from deforming and also avoid the residues from being pressed into the mesh holes, ensuring the filtering efficiency of the filter screen 16. The filtering device is based on a base 1. An installation frame 2 is fixedly installed on the back of the base 1. An oil barrel 3 is installed inside the installation frame 2. A servo motor 4 is fixedly installed at the center position on the top of the base 1. The output end of the servo motor 4 is fixedly connected to a support rod 20. The upper end of the support rod 20 is fixedly connected to a bracket 5. Filtering barrels 6 are rotatably installed on both sides of the bracket 5. The edible oil in the oil barrel 3 flows into the filtering barrel 6. The filtering barrel 6 can filter the edible oil. Driving the servo motor 4 can drive the support rod 20 to rotate. The rotation of the support rod 20 drives the bracket 5 to rotate. The rotation of the bracket 5 drives the filtering barrel 6 to rotate. When too many residues accumulate in one of the filtering barrels 6, the other filtering barrel 6 can be rotated below the oil barrel 3 to continue filtering the edible oil using the other filtering barrel 6. A collection barrel 11 and an extrusion box 12 are respectively movably installed on both sides of the top of the base 1. The edible oil filtered by the filtering barrel 6 can fall into the collection barrel 11 for collection. The filtering barrel 6 with accumulated residues is rotated above the extrusion box 12, and the residues can be poured into the extrusion box 12 to extrude the edible oil in the residues. While extruding, the other filtering barrel 6 can continue to filter the edible oil, realizing continuous filtering of the edible oil and improving the filtering efficiency.

[0026] To optimize the filtering effect of the filtering barrel 6, an arc-shaped filter screen 7 is fixedly installed inside the filtering barrel 6. The arc-shaped filter screen 7 bulges upward. Compared with a flat filter screen, the arc-shaped filter screen has a larger surface area, and more edible oil and residues can be processed per unit area, improving the filtering efficiency. The convex design can increase the gap and the space for the edible oil to pass through. Compared with a flat filter screen, the arc-shaped filter screen 7 can effectively reduce the risk of residue blockage.

[0027] During the process of the filtering barrel 6 rotating above the extrusion box 12, there may be residual edible oil dripping from the filtering barrel 6, which will cause waste of edible oil and pollution to the external environment. To solve this technical problem, an oil guide plate 14 is fixedly connected to the outer surface of the support rod 20 through a connecting rod 13. One end of the oil guide plate 14 close to the collection barrel 11 slopes downward. The oil guide plate 14 is adapted to the rotation route of the filtering barrel 6. The oil guide plate 14 can receive the edible oil dripping from the filtering barrel 6, and the edible oil can flow along the oil guide plate 14 into the collection barrel 11, avoiding waste of edible oil.

[0028] To facilitate pouring out the residues in the filtering barrel 6, refer toFigure 4 As shown, both sides of the filter barrel 6 are fixedly connected with rotating shafts 8. The rotating shafts 8 are rotatably connected to the inner wall of the bracket 5, and a torsion spring 9 is sleeved outside the rotating shafts 8. One end of one of the rotating shafts 8 passes through the bracket 5 and is fixedly connected with a handle 10. Rotating the handle 10 can drive the filter barrel 6 to flip. At this time, the torsion spring 9 deforms, and the residue in the filter barrel 6 can fall into the extrusion box 12. Then, releasing the filter barrel 6, the filter barrel 6 can automatically flip back to its original position through the torsion of the torsion spring 9.

[0029] In order to realize the extrusion and collection of the residue, refer to Figure 5 and Figure 6 As shown, a filter net 16 is slidably installed inside the extrusion box 12. A slope 18 is arranged on the inner bottom wall of the extrusion box 12, and an oil outlet pipe 17 is arranged on one side of the extrusion box 12. Electric push rods 15 are symmetrically installed outside the extrusion box 12. The output ends of the electric push rods 15 extend into the extrusion box 12 and are fixedly connected with a pressing plate 19. The residue falls on the filter net 16. Driving the two electric push rods 15 can extrude the residue. The extruded edible oil can pass through the filter net 16 and fall on the slope 18, and then drain out from the oil outlet pipe 17 along the slope 18. A valve is arranged on the oil outlet pipe 17. When a certain amount of edible oil is collected in the slope 18, the valve can be opened to make the edible oil drain out from the oil outlet pipe 17, and the staff can collect the edible oil.

The control circuit of the controller can be realized by simple programming of those skilled in the art. The provision of the power supply also belongs to the common knowledge in the art. And the present utility model is mainly used to protect mechanical devices, so the control mode and circuit connection of the present utility model will not be explained in detail.
