Description

Technical Field

[0001] This utility model relates to the field of corn oil production technology, and in particular to a corn oil impurity removal device. Background Technology

[0002] In the process of extracting corn oil, whether by pressing or leaching, some impurities are produced, such as corn husk fragments and bran. Existing corn oil impurity removal devices are mainly used to remove impurities from corn oil. By removing these impurities, corn oil can be made purer, and its transparency and color can be improved, thus meeting consumers' demand for high-quality edible oil.

[0003] However, it lacks backflushing and cleaning functions during use. Impurities on the surface of the main filter screen tend to accumulate gradually and are difficult to remove completely. Replacing the filter screen requires additional manpower, which is inefficient. Furthermore, the corn oil remaining in the impurities cannot be effectively recovered. This residual corn oil is disposed of as waste along with the impurities, resulting in a waste of corn oil. Utility Model Content

[0004] The purpose of this invention is to at least solve one of the technical problems existing in the prior art, and to provide a corn oil impurity removal device to improve the extraction rate of corn oil.

[0005] This utility model also provides a corn oil impurity removal device as described above, comprising: a tank, an inlet hopper connected to the upper surface of the tank, a main filter screen fixedly connected to the inner surface of the tank, an arc-shaped scraper rotatably connected to the upper surface of the main filter screen, a bracket fixedly connected to the inner wall of the tank, a waterproof motor fixedly connected to the inner surface of the bracket, the arc-shaped scraper being driven by the waterproof motor, a piston plate slidably connected to the inner wall of the tank, two processing boxes connected to the side surface of the tank, a sliding groove provided on the tank, an electric push rod fixedly connected to the inner surface of the sliding groove, a sealing plate fixedly connected to the lower end of the electric push rod, a secondary filter screen fixedly connected to the inner surface of the processing box, and a lower pressure plate slidably connected to the inner surface of the processing box.

[0006] According to the present invention, a corn oil impurity removal device is provided, wherein the piston plate is located below the main filter screen, the connection between the processing box and the tank is located on the side of the main filter screen, and the sealing plate is movably connected to the connection between the tank and the processing box.

[0013] The corn oil impurity removal device works as follows: after filtration, the sealing plate rises to open the connection between the processing box and the tank. The piston plate then lifts the filtered corn oil, creating a backflushing effect on the main filter screen. This effectively reduces the adhesion of impurities on the main filter screen. Subsequently, the rotating arc-shaped scraper pushes the impurities outward from the connection between the processing box and the tank into the processing box. The backflushing effect, combined with the arc-shaped scraper, efficiently cleans the impurities on the surface of the main filter screen. Inside the processing box, the descending pressure plate squeezes out the impurities, allowing the corn oil within the impurities to be fully discharged, avoiding waste and improving the corn oil extraction rate.

[0021] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0022] Reference Figure 1-4 This utility model provides a corn oil impurity removal device, which includes: a tank 2, a discharge pipe 6 connected to the side surface of the tank 2 for discharging filtered corn oil, a sealing plug 7 movably connected to the inner surface of the discharge pipe 6, a feed hopper 1 connected to the upper surface of the tank 2, and a main filter screen 24 fixedly connected to the inner surface of the tank 2.

[0023] Specifically: Corn oil enters the tank 2 through the feed hopper 1. Under the action of gravity, the corn oil flows downward. The main filter 24 performs preliminary filtration of the corn oil, intercepting impurities such as corn husk fragments and bran, allowing the relatively pure corn oil to continue flowing downward through the filter. The filtered corn oil accumulates at the bottom of the tank 2. When it needs to be discharged, the sealing plug 7 in the discharge pipe 2 6 is opened, and the corn oil flows out of the tank 2 through the discharge pipe 2 6.

[0024] A piston plate 22 is slidably connected to the inner wall of the tank body 2. The piston plate 22 is located below the main filter screen 24. A sleeve 23 is connected to the lower surface of the tank body 2. A hydraulic push rod 14 is fixedly connected to the inner surface of the sleeve 23. The upper end of the hydraulic push rod 14 is fixedly connected to the lower surface of the piston plate 22. A limit rod 13 is fixedly connected to the inner surface of the tank body 2 to limit the minimum height of the piston plate 22 so that its minimum height is aligned with the discharge pipe 6. The upper end of the limit rod 13 is movably connected to the piston plate 22.

[0025] Specifically: When a certain amount of impurities accumulate on the main filter screen 24, affecting the filtration effect, the hydraulic push rod 14 is activated. The hydraulic push rod 14 pushes the piston plate 22 to move upward in the tank 2. Since the piston plate 22 is located below the main filter screen 24, the upward movement of the piston plate 22 will cause the corn oil above it to rise. The rising corn oil will generate a reverse impact force on the main filter screen 24, that is, a backwash effect. This backwash force can effectively reduce the adhesion of impurities above the main filter screen, causing some impurities to fall off the surface of the main filter screen 24.

[0026] An arc-shaped scraper 19 is rotatably connected to the upper surface of the main filter screen 24. A bracket 20 is fixedly connected to the inner wall of the tank body 2. A waterproof motor 21 is fixedly connected to the inner surface of the bracket 20. The arc-shaped scraper 19 is driven by the waterproof motor 21. Two treatment boxes 3 are connected to the side surface of the tank body 2.

[0027] Specifically: While the piston plate 22 is performing a backflushing operation, the waterproof motor 21 starts, driving the arc-shaped scraper 19 to rotate. The arc-shaped scraper 19 is located on the upper surface of the main filter screen 24. The rotating scraper pushes the impurities that have fallen off the surface of the main filter screen 24 and those that have not been backflushed outward. The connection between the treatment box 3 and the tank 2 is located on the side of the main filter screen 24. When the sealing plate 9 rises under the action of the electric push rod 8 to open the connection between the tank 2 and the treatment box 3, the arc-shaped scraper 19 can push the impurities from the connection into the treatment box 3.

[0028] The side surface of the processing box 3 is connected to a discharge pipe 4 for discharging corn oil squeezed out by impurities. A sealing plug 5 is movably connected to the inner surface of the discharge pipe 4. The processing box 3 is provided with a discharge port 10 for discharging impurities. A sealing plug 11 is movably connected to the inner surface of the discharge port 10. The connection between the processing box 3 and the tank 2 is located on the side of the main filter screen 24. The tank 2 is provided with a sliding groove 15. An electric push rod 8 is fixedly connected to the inner surface of the sliding groove 15. A sealing plate 9 is fixedly connected to the lower end of the electric push rod 8. The sealing plate 9 is movably connected to the connection between the tank 2 and the processing box 3. A filter screen 12 is fixedly connected to the inner surface of the processing box 3. A lower pressure plate 18 is slidably connected to the inner surface of the processing box 3. A sleeve 17 is connected to the upper surface of the processing box 3. A hydraulic push rod 16 is fixedly connected to the inner surface of the sleeve 17. The lower end of the hydraulic push rod 16 is fixedly connected to the upper surface of the lower pressure plate 18.

[0029] Specifically: After impurities enter the treatment box 3, they are first further filtered by the filter screen 12 to ensure that the impurities are effectively intercepted in the treatment box 3. When a certain amount of impurities accumulate in the treatment box 3, the hydraulic push rod 16 is activated. The hydraulic push rod 16 pushes the lower pressure plate 18 to move downward in the treatment box 3, applying pressure to the impurities and squeezing out the corn oil in the impurities. The squeezed corn oil flows into the bottom of the treatment box 3 through the holes of the filter screen 12. Then, the sealing plug 5 in the discharge pipe 4 is opened, so that the corn oil is discharged from the treatment box 3 through the discharge pipe 4 and collected for reuse. When the impurities are squeezed to a certain extent, the sealing plug 11 in the discharge port 10 is opened, and the squeezed impurities in the treatment box 3 are discharged from the discharge port 10.

[0030] Working principle: When a certain amount of impurities accumulate on the main filter screen 24, affecting the filtration effect, the hydraulic push rod 14 is activated. The hydraulic push rod 14 pushes the piston plate 22 upward within the tank 2. Since the piston plate 22 is located below the main filter screen 24, its upward movement causes the corn oil above it to rise. The rising corn oil generates a reverse impact force on the main filter screen 24, i.e., a backwashing effect. This backwashing force can effectively reduce the adhesion of impurities above the main filter screen, causing some impurities to fall off the surface of the main filter screen 24. While the piston plate 22 is performing the backwashing operation, the waterproof motor 21 is activated, driving the arc-shaped scraper 19 to rotate. The arc-shaped scraper 19 is located on the upper surface of the main filter screen 24. The rotating scraper pushes the impurities that have fallen off the surface of the main filter screen 24 and those that have not been backwashed outward. The connection between the treatment box 3 and the tank 2 is located on the side of the main filter screen 24. When the sealing plate 9... After the electric push rod 8 rises and opens the connection between the tank 2 and the treatment box 3, the arc-shaped scraper 19 can push the impurities from the connection into the treatment box 3. After the impurities enter the treatment box 3, they are further filtered by the filter screen 12 to ensure that the impurities are effectively intercepted in the treatment box 3. When a certain amount of impurities accumulate in the treatment box 3, the hydraulic push rod 16 is activated. The hydraulic push rod 16 pushes the lower pressure plate 18 to move downward in the treatment box 3, applying pressure to the impurities and squeezing the corn oil in the impurities. The squeezed corn oil flows into the bottom of the treatment box 3 through the holes of the filter screen 12. Then, the sealing plug 5 in the discharge pipe 4 is opened, so that the corn oil is discharged from the treatment box 3 through the discharge pipe 4 and collected for reuse. When the impurities are squeezed to a certain extent, the sealing plug 11 in the discharge port 10 is opened, and the squeezed impurities in the treatment box 3 are discharged from the discharge port 10.

However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
