Description

Technical Field

[0001] This utility model relates to the field of rice bran oil production technology, specifically a separation device for rice bran oil production. Background Technology

[0002] Rice bran oil is rich in various nutrients, such as unsaturated fatty acids, oryzanol, and vitamin E. It has the effects of lowering cholesterol and anti-oxidation, making it a high-quality edible oil. However, during the processing of rice bran into oil, various impurities, such as rice bran fragments, fibers, and dust, will be mixed in. These impurities will affect the appearance and taste of rice bran oil, so a rice bran oil separation device is needed.

[0003] For example, a rice bran oil separation device with authorization announcement number "CN215232650U" uses a rotating mechanism to drive a secondary filter box to rotate via a rotary motor, facilitating secondary filtration. Furthermore, a blocking component prevents the separated oil from entering the stabilizing groove, further ensuring oil separation efficiency and oil quality. However, the filter screen in this device is fixed during rice bran oil separation. Because rice bran oil is sticky, sticky impurities adhere to the filter screen. If the screen is fixed, impurities will gradually accumulate, clogging the filter screen pores and reducing filtration efficiency. Utility Model Content

[0004] The purpose of this invention is to solve the problem that impurities tend to accumulate locally when the filter screen is fixed, causing filter screen blockage and reducing filtration efficiency. Therefore, a separation device for rice bran oil production is proposed.

[0020] The present invention will be further described below with reference to the accompanying drawings:

[0021] See attached document Figure 1-6 In this embodiment, a separation device for rice bran oil production includes a base 1 and a housing 2. The housing 2 is fixedly connected to the upper end of the base 1. An observation window and a maintenance door are installed sequentially from top to bottom on the front end of the housing 2. A first housing 3 is fixedly connected to the upper right side of the housing 2. A filter screen moving structure 4 is provided inside the first housing 3. A square cover 15 is installed on the upper end of the housing 2. The cover 15 is installed on the housing 2 by screws. The inner wall of the square cover 15 is fixedly connected to the first feed inlet 8. The cover is placed above the first feed inlet 8. A preliminary rice bran oil separation structure 5 is provided inside the housing 2. A funnel 9 is fixedly connected to the middle of the inner wall of the housing 2. Leakage holes 14 are opened on both sides of the lower end of the housing 2.

[0022] A second servo motor 13 is fixedly connected;

[0023] The output shaft of the second servo motor 13 is rotatably connected to the housing 2 through a sealed bearing. The output shaft of the second servo motor 13 rotates inside the housing 2 through the sealed bearing. The output shaft of the second servo motor 13 is fixedly connected to the separation cylinder 10. The inner walls of the right square 6 and the crossbar 406 are threadedly connected to the bolts 7. The right bolts 6 fix the second housing 501 and the crossbar 406 together. The lower end of the pulley 506 is slidably connected to the housing 2. The pulley 506 slides inside the housing 2. The pulley 506 converts sliding friction into rolling friction. The coefficient of rolling friction is much smaller than the coefficient of sliding friction, which reduces friction and makes the movement of the second housing 501 smoother. The inner wall of the separation cylinder 10 is provided with multiple oil outlets 12. The oil outlets 12 are filter structures. The upper end of the inner wall of the separation cylinder 10 is fixedly connected to the second feed inlet 11.

[0024] See attached document Figure 1 , Figure 2 , Figure 3 and Figure 4 The filter moving structure 4 includes a first servo motor 401. The outer wall of the first servo motor 401 is fixedly connected to the first housing 3. The output shaft of the first servo motor 401 is fixedly connected to a cam 402. Both ends of the rotating shaft of the cam 402 are rotatably connected to the first housing 3 through bearings. The cam 402 rotates inside the first housing 3 through the bearings. The outer wall of the cam 402 abuts against the vertical plate 403. The inner walls on both sides of the vertical plate 403 are slidably connected to the slide rod 404. The vertical plate 403 slides on the slide rod 404. The slide rod 404 provides sliding support for the vertical plate 403 and makes the vertical plate 403 move only in a straight line.

[0025] Both ends of the slide bar 404 are fixedly connected to the first housing 3. A spring 405 is provided on the left side of the vertical plate 403. Both ends of the spring 405 are fixedly connected to the first housing 3 and the vertical plate 403 respectively. The model of the spring 405 is selected according to actual needs and can meet the working requirements. A crossbar 406 is fixedly connected to the end of the vertical plate 403. The outer wall of the crossbar 406 is slidably connected to the first housing 3. A sealing rubber gasket is provided at the position where the crossbar 406 contacts the box 2. The crossbar 406 slides inside the first housing 3.

[0026] See attached document Figure 1 and Figure 5The preliminary separation structure 5 for rice bran oil includes a second housing 501. A filter screen 502 is fixedly connected to the lower end of the second housing 501. A heating block 503 is installed on the inner wall of the second housing 501. The heating block 503 passes through the housing 2 and is connected to an external power source through the cooperation of a wire and a sealing ring. The heating block 503 heats the second housing 501 and can heat the filter screen 502, thereby increasing the temperature of the rice bran oil. The heated rice bran oil has reduced viscosity and increased fluidity, allowing it to pass through the filter screen 502 more smoothly. Both ends of the second housing 501 are fixedly connected to square blocks 6. The left square block 6 is threadedly connected to the inner wall of the straight plate 504 with bolts 7. The bolts 7 fix the straight plate 504 to the left square block 6. The left end of the second housing 501 is fixedly connected to the straight plate 504.

[0027] The straight plate 504 is slidably connected to the protrusion 505 through the protrusions machined on the upper and lower sides. The straight plate 504 slides on the protrusion 505 through the protrusions machined on the upper and lower sides. The end of the protrusion 505 can prevent the protrusions machined on the upper and lower sides of the straight plate 504 from sliding out. The end of the protrusion 505 is fixedly connected to the housing 2. The end of the straight plate 504 is equipped with a pulley 506.

[0028] Working principle:

[0029] When using a separation device for rice bran oil production:

[0030] Initial separation:

[0031] The operator removes the cover from the feed inlet 8 and pours the rice bran oil through the feed inlet 8. The rice bran oil falls onto the filter screen 502 through the feed inlet 8. The heating block 503 is turned on, and the heating block 503 heats the filter screen 502, which raises the temperature of the rice bran oil on the filter screen 502. The heated rice bran oil has reduced viscosity and increased fluidity, allowing it to pass through the filter screen 502 more smoothly.

[0032] When the external power supply of the first servo motor 401 is connected and the first servo motor 401 is started, the output shaft of the first servo motor 401 rotates, which drives the cam 402 to rotate. The rotation of the cam 402 drives the vertical plate 403 to slide on the slide rod 404. The slide rod 404 provides sliding support for the vertical plate 403 and makes the vertical plate 403 move only in a straight line. The vertical plate 403 moves to the left, which compresses the spring 405. The movement of the vertical plate 403 drives the horizontal rod 406 to move. The movement of the horizontal rod 406 drives the second housing 501 to move. The movement of the second housing 501 drives the straight block 504 to slide on the convex rod 505. The end of the convex rod 505 can prevent the protrusions processed on the upper and lower sides of the straight plate 504 from sliding out. The movement of the straight plate 504 causes the pulley 506 to roll in the housing 2. The pulley 506 converts sliding friction into rolling friction. The coefficient of rolling friction is much smaller than the coefficient of sliding friction, which reduces friction and makes the movement of the second housing 501 smoother. The movement of the second housing 501 causes the rice bran oil on the filter screen 502 to move.

[0033] When the vertical plate 403 moves to the leftmost end (e.g.) Figure 3 As the output shaft of the first servo motor 401 continues to rotate, the spring 405 rebounds, causing the vertical plate 403 to remain in contact with the cam 402, thus moving the vertical plate 403 to the right. The vertical plate 403 drives the filter screen 502 to move to the right through the above connection method, thereby causing the filter screen 502 to reciprocate linearly in the left and right direction. The reciprocating movement of the filter screen 502 makes it difficult for impurities to continuously adhere to the same position, reducing impurity accumulation and lowering the risk of clogging. To further explain, most of the impurities are left on the filter screen 502 during the above process, and a small amount of impurities flow with the rice bran oil through the filter screen 502 to the funnel 9. The impurities on the funnel 9 flow into the second feed inlet 11 and enter the separation cylinder 10. When the rice bran oil in the separation cylinder 10 reaches one-third through the observation window at the front of the box 2, the pouring of rice bran oil is stopped, thus completing the initial separation of rice bran oil.

[0034] Secondary separation of rice bran oil:

[0035] Place the rice bran oil collection bucket below the two drain holes 14, open the maintenance door by rotating the screws, insert the mesh bag into the separator 10 through the second feed port 11, and fix the mesh bag to the separator 10 with clamps. Then close the maintenance door, connect the external power supply to the second servo motor 13, and start the second servo motor 13. The output shaft of the second servo motor 13 rotates, driving the separator 10 to rotate. Rice bran oil has a relatively high density, while impurities have a low density. When the rice bran oil rotates at high speed in the separator 10, it generates a strong centrifugal force. Under the action of centrifugal force, the impurities... Rice bran oil with a higher viscosity experiences greater centrifugal force and will move towards the outer wall of the separation cylinder 10. It will be thrown out of the separation cylinder 10 through the oil outlet 12 and fall into the box 2. The separated rice bran oil will flow into the rice bran oil collection bucket outside through the leakage hole 14 at the lower end of the box 2. The working method of the separation cylinder 10 is the same as that of the secondary filter box in a rice bran oil production separation device with authorization announcement number "CN215232650U". It is a differential centrifugation method. After the rice bran oil is collected, all power is turned off, thus completing the working process of the separation device for rice bran oil production.

[0036] Remove the screws on the square cover 15, remove the square cover 15, remove the first housing 501 by rotating the bolt 7, clean the filter screen 502, open the maintenance door in the above manner, remove the clamps that fix the mesh bag, remove the mesh bag, and clean the inside of the box 2 and the separation cylinder 10 with tools such as a water gun (a magnetic sealing gasket is installed at the joint between the maintenance door and the box 2). After cleaning, reset the first housing 501 and the maintenance door.
