Description

Technical Field

[0001] The present invention belongs to the technical field of grain and oil machinery, and specifically relates to a purification device for rapeseed oil production. Background Art

[0002] In the production process of rapeseed oil, purification is a crucial step. Traditional rapeseed oil purification methods often have problems such as low oil yield, unstable oil quality, and low purification efficiency. In order to improve the oil yield and quality of rapeseed oil, people have been constantly exploring and improving the rapeseed oil purification process;

[0003] Most traditional rapeseed oil purification devices use simple filtration methods, filtering crude oil through filter screens or filter cloths to remove impurities and solid particles therein. However, this filtration method has obvious defects, such as poor filtration effect, easy clogging of the filter screen, and difficulty in completely removing tiny impurities. In addition, traditional purification devices often cannot fully extract rapeseed oil during the pressing process, resulting in a low oil yield and wasting resources;

[0004] In addition, although some advanced rapeseed oil purification devices use more complex processes and equipment, such as centrifugal separation, ultrafiltration, membrane separation and other technologies, these technologies often have problems such as high cost, complex operation, and difficult maintenance in actual applications, and are difficult to be widely used in small and medium-scale production;

[0005] In order to overcome the deficiencies of traditional rapeseed oil purification devices and improve the oil yield and oil quality, people have begun to develop new purification devices. These new devices usually combine multiple purification technologies, such as pressing, filtering, adsorption, etc., to achieve a more efficient and thorough purification effect.

[0053] As Figure 2 shown, in some embodiments, a hydraulic cylinder 2 is fixedly connected above the filtration bin 1.

[0054] As Figures 2-5 shown, in some embodiments, the extrusion assembly 3 includes an extrusion plate 301. The outer surface of the extrusion plate 301 fits against the inner wall of the filtration bin 1. An extrusion block 304 is fixed below the extrusion plate 301. An installation groove is formed in the extrusion block 304, and a filter head 314 is fixed in the installation groove. The filter head 314 is used to filter rapeseed oil residues.

[0057] As Figures 2-4 shown, in some embodiments, a vacuum groove 302 is formed inside the extrusion plate 301. The vacuum groove 302 includes an upper bottom surface and a lower bottom surface. A plurality of first oil suction holes 303 are formed in the lower bottom surface of the vacuum groove 302. Each first oil suction hole 303 is fixed to the extrusion block 304. An oil suction hole 305 and an oil suction hole 307 are formed inside the extrusion block 304. One end of the first oil suction hole 303 is communicated with one end of the oil suction hole 305 and the diameters of the first oil suction hole 303 and the oil suction hole 305 are the same. One end of the oil suction hole 307 is communicated with the other end of the oil suction hole 305. The other end of the oil suction hole 307 is formed on both sides of the filter head 314 and is communicated with an oil suction hole 306 inside the filter head 314.

[0058] As Figures 2-5 shown, in some embodiments, an oil pump 312 is fixedly connected to the upper bottom surface of the vacuum groove 302. The oil pump 312 includes an oil inlet and an oil outlet. An oil suction pipe 313 is fixedly connected to the oil inlet of the oil pump 312. One end of the oil suction pipe 313 is fixedly connected to the oil inlet of the oil pump 312, and the other end of the oil suction pipe 313 is fixedly connected to the first oil suction hole 303.

[0059] By starting the hydraulic cylinder 2, the output rod of the hydraulic rod 2 drives the extrusion assembly 3 to move downward and cooperate with the filtering assembly 5. The filter residue on the filtering assembly 5 is extruded by the extrusion plate 301 and the extrusion block 304, and part of the rapeseed oil inside is extruded and absorbed by the filter cotton 311. By starting the oil pump 312, the rapeseed oil inside the oil suction hole 307 is sucked into the oil pump 312 under the action of the oil pump 312 through the oil suction hole 305, the first oil suction hole 303 and the oil suction pipe 313. The rapeseed oil in the oil pump 312 is discharged into the vacuum groove 302 through the oil outlet of the oil pump 312.

[0060] As Figure 6 shown, in some embodiments, the filtering assembly 5 includes a first filter plate 501 and a second filter plate 502, where:

[0061] The thickness of the first filter plate 501 is greater than that of the second filter plate 502. The first filter plate 501 and the second filter plate 502 are in contact with the inner wall of the filter bin 1. A number of first filter holes 506 are formed in the first filter plate 501. The first filter holes 506 are adapted to the extrusion blocks 304. The first filter holes 506 are used to filter larger rapeseed oil residues. A number of second filter holes 507 are formed in the second filter plate 502. The second filter holes 507 are used to filter smaller rapeseed oil residues. The first filter holes 506 and the second filter holes 507 are concentrically matched. The aperture of the first filter holes 506 is greater than that of the second filter holes 507. A first motor slot 503 is formed in the second filter plate 502. A first motor 504 is installed in the first motor slot 503. The first motor 504 includes a first motor output shaft. The first motor output shaft is installed on the first filter plate 501. A threaded hole 505 is formed in the first filter plate 501 on the side where it is located on one side of the second filter plate 502. One end of the threaded hole 505 is opened on the first filter plate 501 on the side where it is located on one side of the second filter plate 502, and the other end of the threaded hole 505 is opened inside the first filter plate 501. The threaded hole 505 is threadedly connected to the first motor output shaft.

[0062] The filter assembly 5 is in a filtering state and an extrusion state. In the filtering state, at this time, the top end of the first motor output shaft is located in the middle of the threaded hole 505. The rapeseed oil passes through the first filter holes 506 and the second filter holes 507 for two-stage filtering. The first filter holes 506 are used to filter larger rapeseed oil residues, and the second filter holes 507 are used to filter smaller rapeseed oil residues.

[0063] In the extrusion state, the first motor 504 is started. When the first motor output shaft reaches the top end of the threaded hole 505 by the rotation of the first motor output shaft, at this time, the lower surface of the first filter 501 is in contact with the upper surface of the second filter plate 502, and the first filter holes 506 and the second filter holes 507 are not communicated.

[0064] Through the contact between the first filter 501 and the second filter plate 502, the rapeseed oil residues between the first filter 501 and the second filter plate 502 are squeezed to extract oil and flow out from the second filter holes 507.

[0065] After the extrusion is completed, at this time, the second filter plate 502 serves as a support plate. The hydraulic cylinder 2 does work to move the extrusion assembly 3 downward to contact the upper surface of the first filter plate 501 with the extrusion plate. The extrusion block 304 squeezes the first filter holes 506 to extract oil from the rapeseed oil residues on the upper surface of the first filter plate 501 to improve the oil yield.

[0066] Such as Figure 1As shown, in some embodiments, a filter chamber door 103 is provided on the filter chamber 1. The position where the filter chamber door 103 is provided is parallel to the filter assembly 5, and the filter chamber door 103 is adapted to the filter assembly 5. An oil inlet 101 and an oil outlet 102 are provided on the filter chamber 1. The oil inlet 101 is located between the extrusion assembly 3 and the filter assembly 5, and the oil inlet 101 is used for pouring rapeseed oil. The oil outlet 102 is located at the bottom of the filter chamber 1, and the oil outlet 102 is connected to the oil storage chamber 6 through a pipeline. The oil outlet 102 is used for transporting the filtered rapeseed oil to the oil storage chamber 6.

[0067] As Figure 1 shown, in some embodiments, the oil storage chamber 6 is fixedly connected to the filter chamber 1 through a bracket. The oil storage chamber 6 is located below the filter chamber 1. An oil inlet 601 is provided on the oil storage chamber 6, and the oil inlet 601 and the oil outlet 102 are connected through a pipeline. The oil inlet 601 is used for receiving the rapeseed oil transported from the filter chamber 1.

[0068] As Figure 8 shown, in some embodiments, the oil storage chamber 6 includes a heater 602, a baffle 603, and an activated carbon plate 604, where: the heater 602 is fixed at the bottom of the oil storage chamber 6, the baffle 603 is fixed on the inner wall of the oil storage chamber 6, the baffle 603 is located above the heater 602, and the baffle 603 is used to block the rapeseed oil to protect the heater 602 from direct contact and possible damage; the activated carbon plate 604 is fixed on the inner wall of the oil storage chamber 6, the activated carbon plate 604 is located at the top inside the oil storage chamber 6, and the activated carbon plate 604 is used to adsorb the odor in the rapeseed oil and improve the quality of the oil product.

[0069] An exhaust port 605 is provided above the oil storage chamber 6, and the exhaust port 605 is used for discharging the odor. An oil inlet 606 is also provided on the oil storage chamber 6, and the oil inlet 606 is connected to the cleaning chamber 4 through a pipeline.

[0070] By starting the first heater 602, the rapeseed oil located on the baffle 603 is heated. The purpose of heating is to increase the activity of the oil to evaporate the moisture in the rapeseed oil and accelerate the volatilization of peculiar smells. As the first heater 602 heats up, the moisture in the rapeseed oil begins to evaporate, and at the same time, the peculiar smell substances also start to volatilize. These volatilized peculiar smell substances will flow in the oil storage tank 6 along with the air current. During the flowing process, the volatilized peculiar smell substances will encounter the activated carbon plate 604. The activated carbon plate 604 has a strong adsorption capacity and can effectively adsorb these peculiar smell substances, thereby purifying the smell of the rapeseed oil. After being adsorbed by the activated carbon plate 604, the remaining waste gas (mainly water vapor and other non-adsorbable gases) will be discharged from the exhaust port 605 out of the oil storage tank 6 to keep the air in the oil storage tank 6 fresh.

[0071] As Figure 9 shown, in some embodiments, the volume of the cleaning tank 4 is larger than the volume of the filtering tank 1. A cleaning tank door 408 is provided on the cleaning tank 4, and the cleaning tank door 408 is adapted to the filtering assembly 5.

The filter net 402 is located below the cleaning tank door 408 and is spaced from the cleaning tank door 408 by a certain distance. The filter net 402 is used to store rapeseed oil residues. The oil storage tank 403 is fixed below the filter net 402 and is used to store the rapeseed oil adhering to the rapeseed oil residues. A second heater 405 is fixed below the oil storage tank 403. The second heater 405 is used to heat the rapeseed oil in the oil storage tank 403 and the rapeseed oil residues on the filter net 402; by heating the rapeseed oil adhering to the rapeseed oil residues, it is made to drip into the oil storage tank 403.

[0073] On one side of the oil storage tank 403, a second motor 404 is installed. The second motor 404 is fixed on the outer wall of the cleaning bin 4. The second motor 404 includes a second motor output shaft. The second motor output shaft is fixed to the oil storage tank 403. The oil storage tank 403 is driven to rotate by the second motor. The filter screen 402 and the oil storage tank 403 are designed with a wider upper part and a narrower lower part, which facilitates the second motor 404 to drive the oil storage tank 403 and the filter screen 402 to flip in the cleaning bin 4, so that the rapeseed oil residue on the filter screen 402 is poured into the collection box 406. At the other end of the oil storage tank 403, a second oil outlet 407 is provided. The second oil outlet 407 penetrates the cleaning bin 4. The second oil outlet 407 is connected to the third oil inlet 606 through a pipeline. The rapeseed oil on the rapeseed oil residue at the second oil outlet 407 is transported to the oil storage bin 6 through the third oil inlet 606.

[0074] As Figure 7 and Figure 10 shown, in some embodiments, a rotating assembly 7 is further included. The rotating assembly 7 includes a support base 701, a rotating shaft 702, a connecting rod 703, a rotating block 704 and a fixed shaft 706, where:

[0075] The support base 701 is in contact with the ground to support the rotating assembly 7. The fixed shaft 706 is fixed on the support base 701. The rotating shaft 702 is rotatably connected to the fixed shaft 706. The connecting rod 703 is fixedly connected to the outer diameter of the rotating shaft 702. A linear drive is installed inside the rotating shaft 702. The linear drive drives the rotating shaft 702 to rotate. A second motor slot is provided inside the rotating shaft 702. A third motor 705 is fixed in the second motor slot. The third motor 705 includes a third motor output shaft. One end of the rotating block 704 is fixedly connected to the third motor output shaft. The other end of the rotating block 704 is fixedly connected to the outer diameter of the first filter plate 501.

[0076] By opening the filter bin door 103 and the cleaning bin door 408, the linear drive controls the rotating shaft 702 to rotate the filter assembly 5 from the filter bin 1 to the cleaning bin 4. Then, the third motor 705 is started, and the filter assembly 5 is rotated as a whole through the rotating block 704, so that the plate surface of the filter assembly 5 is perpendicular to the ground. The rapeseed oil residue in the filter assembly 5 falls under the action of gravity, which facilitates subsequent cleaning and processing.

[0077] Embodiment 1. Based on the above device, a purification method for a rapeseed oil production and purification device is provided:

[0078] Pour rapeseed oil into the oil inlet 101. The rapeseed oil flows through the filtering component 5 to the bottom of the filtering bin 1, enters the oil storage bin 6 through the first oil outlet 102 and the second oil inlet 601. By starting the first heater 602, the rapeseed oil located on the baffle 603 is heated. The purpose of heating is to increase the activity of the oil, evaporate the moisture in the rapeseed oil, and accelerate the volatilization of peculiar smells. As the first heater 602 heats up, the moisture in the rapeseed oil begins to evaporate, and at the same time, the peculiar smell substances also begin to volatilize. These volatilized peculiar smell substances will flow in the oil storage bin 6 along with the air current. The volatilized peculiar smell substances will encounter the activated carbon plate 604 during the flowing process. The activated carbon plate 604 has a strong adsorption capacity and can effectively adsorb these peculiar smell substances, thereby purifying the smell of rapeseed oil. After being adsorbed by the activated carbon plate 604, the remaining waste gas (mainly water vapor and other non-adsorbable gases) will be discharged from the exhaust port 605 out of the oil storage bin 6 to keep the air in the oil storage bin 6 fresh.

[0079] Example 2. Based on Example 1, the following supplements are made to the above method:

[0080] After pouring the rapeseed oil into the filtering bin 1, the crude rapeseed oil is filtered in two stages through the first filtering hole 506 and the second filtering hole 507 respectively. The first filtering hole 506 is used to filter larger rapeseed oil residues, and the second filtering hole 507 is used to filter smaller rapeseed oil residues.

[0081] After filtering is completed, start the first motor 504. When the output shaft of the motor reaches the top of the threaded hole 505 by rotating the output shaft of the first motor, at this time, the lower surface of the first filter 501 contacts the upper surface of the second filter plate 502. Through the contact between the first filter 501 and the second filter plate 502, the impurities with rapeseed oil between the first filter 501 and the second filter plate 502 are squeezed to extract oil and flow out through the second filtering hole 507. At this time, the second filter plate 502 serves as a support plate. By starting the hydraulic cylinder 2, the output rod of the hydraulic rod 2 drives the extrusion component 3 to move downward and cooperate with the filtering component 5. The filter residues on the filtering component 5 are squeezed by the extrusion plate 301 and the extrusion block 304, and part of the rapeseed oil inside is squeezed out and absorbed by the filter cotton 311. By starting the oil pump 312, the rapeseed oil inside the fourth oil suction hole 307 is sucked into the oil pump 312 through the second oil suction hole 305, the first oil suction hole 303 and the oil suction pipe 313 under the action of the oil pump 312. The rapeseed oil in the oil pump 312 is discharged into the vacuum tank 302 through the oil outlet of the oil pump 312. Start the first motor 504, and reverse the output shaft of the first motor to return it to the initial position, so that the first filtering hole 506 and the second filtering hole 507 are coaxial.

[0082] Embodiment 3 makes the following supplement to the above method based on Embodiment 1:

[0083] After extrusion, there is still rapeseed oil residue on the filter assembly 5 at this time. By opening the filter bin door 103 and the cleaning bin door 408, the rotation shaft 702 is controlled by linear drive, so that the filter assembly 5 rotates from the filter bin 1 to the cleaning bin 4. Then start the third motor 705, and rotate the entire filter assembly 5 through the rotating block 704, so that the plate surface of the filter assembly 5 is perpendicular to the ground. The rapeseed oil residue in the filter assembly 5 falls onto the filter screen 402 under the action of gravity. The rapeseed oil attached to the rapeseed oil residue is heated by the heater 405 so that it drips into the oil storage tank 403. The rapeseed oil in the oil storage tank 403 is transported to the oil storage bin 6 through the second oil outlet 407 and the third oil inlet 606.

[0084] After the transportation is completed, the oil storage tank 403 is driven by the second motor to rotate, so that the oil storage tank 403 and the filter screen 402 are flipped in the cleaning bin 4, and the rapeseed oil residue on the filter screen 402 is poured into the collection box 406. The rapeseed oil residue is collected by the collection box 406;

[0085] The rotation shaft 702 is controlled by linear drive, so that the filter assembly 5 rotates from the cleaning bin 4 to the filter bin 1. By starting the oil pump 312, the rapeseed oil in the vacuum tank 302 is discharged from the filter cotton 311 through the second oil suction hole 305, the first oil suction hole 303 and the fourth oil suction hole 307, passes through the filter assembly 5, and is discharged into the bottom of the filter bin 1. Repeat the steps of Embodiment 1.
