An oil residue treatment device for edible oil processing

Abstract

This utility model relates to the technical field of oil residue treatment devices, specifically an oil residue treatment device for edible oil processing. It includes an extrusion assembly, a filter assembly on one side of the extrusion assembly, and a filter barrel. A conical filter screen is rotatably connected to the bottom of the inner cavity of the filter barrel. A second oil delivery pipe is located at the bottom of the inner cavity of the conical filter screen, and a funnel is fixedly connected to the top of the second oil delivery pipe. This oil residue treatment device for edible oil processing collects the extruded oil by having it pass through an oil outlet channel into the funnel. Since the oil may still contain oil residue powder and other impurities, the centrifugal force generated by the rotation of the conical filter screen inside the filter barrel separates the oil residue powder and impurities from the oil. The filtered oil then passes through the second oil outlet pipe into a collection device inside the control box for further processing, reducing the problems of numerous processing steps and long processing times caused by internal impurities.

Description

Technical Field

[0001] This utility model relates to the technical field of oil residue treatment devices, specifically an oil residue treatment device for edible oil processing. Background Technology

[0002] Edible oil is a liquid or solid oil product made from edible vegetable oilseeds, crude vegetable oil, or animal tissues through processes such as pressing, leaching, and refining, which can be directly consumed by humans. Its core component is triglycerides (esterifications of fatty acids and glycerol), and it must meet national food safety standards.

[0003] Patent document CN218307696U discloses a device for treating edible oil pressing residue, including a support leg with a mixing box welded to the top of the support leg. A crushing box is installed on the top of the mixing box, and a low-speed motor is installed on the top surface of the mixing box. This prior art uses components in the crushing box to crush the oil residue. After the crushed oil residue enters the mixing box, two rotating rollers rotate the mixing rod to fully mix the oil residue powder with the auxiliary materials for making feed or fertilizer, so that the oil residue can be secondary processed to make fertilizer or feed, thereby improving the utilization value of the oil residue. Furthermore, since the oil residue itself contains a lot of oil, a lot of oil residue powder adheres to the inner walls of the crushing box and the mixing box. A water pump pumps water into the nozzle, and the water is sprayed into the crushing box and the mixing box, cleaning the oil residue powder adhering to the inner walls of the crushing box and the mixing box by washing with water.

[0004] However, there are some drawbacks. Due to the high impurity content of the crude oil after mechanical pressing, it needs to be filtered multiple times to meet the standards, resulting in high subsequent processing costs and extended processing time for edible oil residue. Therefore, we propose an oil residue treatment device for edible oil processing. Utility Model Content

[0005] One of the technical problems this application aims to solve is that the crude oil contains a lot of impurities after mechanical pressing, requiring multiple filtrations to meet the standards, resulting in high subsequent processing costs and prolonging the processing time of edible oil residue. To solve the above-mentioned technical problems, this application provides an oil residue treatment device for edible oil processing, including an extrusion assembly. A filter assembly is provided on one side of the extrusion assembly. The filter assembly includes a filter barrel. A conical filter screen is rotatably connected to the bottom of the inner cavity of the filter barrel. A second oil delivery pipe is provided at the bottom of the inner cavity of the conical filter screen. A funnel is fixedly connected to the top of the second oil delivery pipe.

[0006] In some embodiments, the extrusion assembly includes a control box, an extrusion member is connected to one side of the control box by screws, an extrusion groove is provided inside the extrusion member, oil outlet grooves are provided on the surface of the extrusion groove, a through hole is provided at the top of one end of the extrusion groove, an oil pressing roller is rotatably connected inside the extrusion groove, and an oil trough is provided at an angle below the extrusion member.

[0007] In some embodiments, a feed hopper is provided at one top end of the extruder, the feed hopper is connected to the extrusion groove through a through hole, a discharge hole is provided at the other end of the extruder, and a discharge plate is provided below the control box.

[0008] In some embodiments, a drive motor is provided at the bottom of the inner cavity of the control box, and the output end of the drive motor is connected to a transmission box via a belt. The output end of the transmission box is fixedly connected to one end of the oil pressing roller.

[0009] In some embodiments, the filter barrels are symmetrically arranged about the oil tank, a flow divider is fixedly connected between the funnels, a rotating motor is provided at the bottom of the filter barrel, the output end of the rotating motor is fixedly connected to the bottom of the conical filter screen, and a first oil outlet pipe is provided at one end of the bottom of the filter barrel.

[0010] In some embodiments, the inner wall of the second oil pipe is surrounded by guide vanes, and oil outlet holes are opened around the bottom of the second oil pipe. The surface of the filter barrel is provided with a second oil outlet pipe, one end of the second oil outlet pipe is connected to the first oil pipe, and one end of the first oil pipe is connected to the interior of the control box.

[0011] This utility model has at least the following beneficial effects: 1. This utility model uses the rotation of the oil pressing roller to squeeze the residual oil inside the oil residue. The squeezed oil flows into the inside of the funnel through the oil outlet groove for collection. Since the oil may still contain oil residue powder and other impurities, the centrifugal force generated by the rotation of the conical filter screen inside the filter bucket separates the oil residue powder and impurities from the oil. The filtered oil then enters the collection device inside the control box through the second oil outlet pipe for collection and further processing, reducing the problem of multiple processing steps and long processing time caused by internal impurities.

[0012] 2. This utility model uses a guide vane installed inside the second oil delivery pipe to cause the oil flow to rotate during the downward flow of the oil, preventing particle sedimentation, reducing the oil delivery resistance, and allowing the oil to quickly enter the filter barrel through the second oil delivery pipe for centrifugal separation. At the same time, the processed oil residue is discharged outward through the other end outlet of the extruder via the discharge plate, avoiding manual intervention in the discharge and improving the efficiency of oil residue treatment.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Example 1: Please refer to Figure 1-5This utility model provides a technical solution: an oil residue treatment device for edible oil processing, including an extrusion assembly 1, a filter assembly 2 on one side of the extrusion assembly 1, the filter assembly 2 including a filter barrel 21, a conical filter screen 24 rotatably connected to the bottom of the inner cavity of the filter barrel 21, a second oil delivery pipe 25 provided at the bottom of the inner cavity of the conical filter screen 24, and a funnel 22 fixedly connected to the top of the second oil delivery pipe 25. After the extruded oil flows through the oil tank 14 to the surface of the diverter plate 23, it is diverted by the diverter plate 23 to the interior of the funnels 22 at both ends. A guide vane 250 is installed on the inner wall of the oil pipe 25. The guide vane 250 is welded to the inner wall of the second oil pipe 25 at an inclination angle of 30 degrees, which causes the oil flow to generate a swirling motion, prevents particles from settling, and reduces the transport resistance. The grease enters the interior of the conical filter screen 24 through the oil outlet 26. The conical filter screen 24 rotates under the drive of the rotating motor 27. The grease containing sludge enters the interior of the high-speed rotating conical filter screen 24. Due to the difference in density, the substances generate different movement trajectories. The oil sludge powder and impurities are thrown outward by centrifugal force, and the grease gathers towards the center and enters the interior of the filter barrel 21.

[0017] Please see Figure 1-4 The extrusion assembly 1 includes a control box 11. An extrusion component 18 is screwed to one side of the control box 11. An extrusion groove 182 is formed inside the extrusion component 18. Parallel oil outlet grooves 180 are formed on the surface of the extrusion groove 182. A through hole 181 is formed at the top of one end of the extrusion groove 182. An oil pressing roller 13 is rotatably connected inside the extrusion groove 182. An oil trough 14 is inclinedly arranged below the extrusion component 18. A feed hopper 12 is provided at one top end of the extrusion component 18, communicating with the extrusion groove 182 through the through hole 181. A discharge hole 110 is formed at the bottom of the other end of the extrusion component 18. A discharge plate 15 is provided below the control box 11. A discharge port 110 is provided at the bottom of the inner cavity of the control box 11. A drive motor 16 is provided, and its output end is connected to a transmission box 17 via a belt. The output end of the transmission box 17 is fixedly connected to one end of the oil pressing roller 13. The control box 11 is used to house the drive motor 16. At the same time, the drive motor 16 drives the gear inside the transmission box 17 to rotate via the belt and the pulley, so that the oil pressing roller 13 presses the oil residue conveyed from the feed hopper 12 inside the extruder 18. Support frames are provided at both ends of the extruder 18 to fix the extruder 18 above the oil tank 14. Since the spiral density of the front half of the oil pressing roller 13 is less than that of the rear half, the oil residue can be deeply pressed. The pressed oil residue can also be used to directly feed poultry or make organic fertilizer.

[0018] Please see Figure 2 , 5The filter barrel 21 is symmetrically arranged about the oil tank 14. A diverter plate 23 is fixedly connected between the funnels 22. A rotating motor 27 is installed at the bottom of the filter barrel 21. The output end of the rotating motor 27 is fixedly connected to the bottom of the conical filter screen 24. A first oil outlet pipe 28 is installed at one end of the bottom of the filter barrel 21. A guide plate 250 is arranged around the inner wall of the second oil supply pipe 25. Oil outlet holes 26 are opened around the bottom of the second oil supply pipe 25. A second oil outlet pipe 29 is installed on the surface of the filter barrel 21. One end of the second oil outlet pipe 29 is connected to the first oil supply pipe 19. One end of the first oil supply pipe 19 is connected to the inside of the control box 11. The diverter plate 23 is used to divert the pressed oil so that the oil flows evenly into the inside of the funnels 22 at both ends and flows along the guide plate. The oil slab 250 flows rapidly into the bottom of the second oil supply pipe 25 and enters the interior of the conical filter screen 24 through the oil outlet 26. Under the action of centrifugal force, the oil residue powder and impurities in the oil are intercepted on the surface of the conical filter screen 24. The filtered oil enters the interior of the filter barrel 21 and is transported to the collection device set inside the control box 11 through the first oil outlet pipe 28 or the second oil outlet pipe 29 for collection in order to proceed to the next step of processing. Since the side of the diverter plate 23 is fixedly connected to the outer wall of the control box 11 by screws, the second oil supply pipe 25 will not rotate when the conical filter screen 24 rotates. The oil can be evenly entered into the conical filter screen 24 through the oil outlet 26 and filtered by the conical filter screen 24 under the action of centrifugal force.

[0019] Example 2: Please refer to Figure 6 The difference between this embodiment and Embodiment 1 is that this utility model provides a technical solution: an oil residue treatment device for edible oil processing, including a filter barrel 21, a conical filter screen 24 rotatably connected to the bottom of the inner cavity of the filter barrel 21, a second oil delivery pipe 25 provided at the bottom of the inner cavity of the conical filter screen 24, a funnel 22 fixedly connected to the top of the second oil delivery pipe 25, and a heating plate 220 provided at the top of the funnel 22. Since the fluidity of oil is low at low temperatures, the flow speed is slow when it enters the interior of the funnel 22 through the oil tank 14. Heating the oil flowing into the surface of the heating plate 220 can accelerate the rate at which the oil passes through the second oil delivery pipe 25. At the same time, heating wires can also be provided inside the oil tank 14 to make the flow rate of the pressed oil faster, thereby accelerating the processing speed of the oil residue by the device.
