Description

Technical Field

[0001] The invention relates to the technical field of biological industry, and in particular to a rapeseed oil efficient separation and extraction device. Background Art

[0002] The rapeseed oil high-efficiency separation and extraction device is usually used to separate the impurities and glycerides in rapeseed oil, and the glycerides are crystallized through winterization reaction and then filtered through a filter plate;

[0003] When filtering impurities and solid oils, the existing device uses a filter plate to filter solid impurities in rapeseed oil. However, since rapeseed oil itself has a certain viscosity, impurities can easily block the sieve holes of the filter plate, resulting in poor filtration. Therefore, it is necessary to improve the problem of easy clogging of the filter plate. Summary of the invention

[0004] The present invention provides the following technical solutions:

[0005] A rapeseed oil efficient separation and extraction device comprises an extraction box, wherein a filter plate is arranged in the middle of the extraction box, and the filter plate is used to filter impurities in the rapeseed oil;

[0006] The filter plate divides the upper and lower parts of the extraction box into an upper chamber and a lower chamber;

[0007] The inner wall of the extraction box is connected with a flange, a lifting ring is arranged above the flange, a limiting block is connected around the bottom of the lifting ring, a limiting groove is arranged around the flange, and the limiting block is slidably connected with the limiting groove;

[0008] The top of the filter plate is fixedly connected to the bottom of the limit block, and the lifting ring can drive the filter plate to reciprocate up and down under the action of the driving device;

[0009] The filter plate is driven up and down by a driving device, so that the filter plate vibrates, so that when impurities or solid fat particles in the filter plate are filtered, the sieve holes on the filter plate are not easily blocked, thereby improving the filtering efficiency.

[0010] Preferably, the inner wall of the extraction box is further connected with a guide sleeve, the bottom of the guide sleeve extends to the inner side of the filter plate, and a first spring is connected between the top of the lifting ring and the top of the inner wall of the guide sleeve, and the first spring presses the lifting ring downward;

[0011] Through the action of the first spring, when the power source for the up and down movement of the lifting ring and the filter plate is cut off, the lifting ring continues to exert a force on the first spring under the action of inertia and gravity, and the first spring generates a reaction force to continue to make the lifting ring move up and down, so that the up and down movement of the lifting ring continues for a short period of time, thereby allowing the blockage in the sieve holes on the filter plate to be detached.

[0012] Preferably, a magnetic rod is provided inside the lower chamber, and the magnetic rod has one or more magnetic rods, and the multiple magnetic rods are symmetrically arranged along the central axis of the lower chamber. The bottom of the lifting ring is connected to one or more magnets, and the multiple magnets are symmetrically arranged along the central axis of the lifting ring. The bottom of the magnet has the same magnetic pole as the top of the magnetic rod. When the top of the magnetic rod is close to the magnetic field of the magnet, under the action of repulsion of like poles, the magnet and the lifting ring move upward synchronously.

[0013] Preferably, there is a gap between the limit block and the inner wall of the limit groove, and there is a gap between the periphery of the lifting ring and the inner wall of the extraction box;

[0014] By setting the magnetic rod and the magnet, when the top of the magnetic rod is close to the magnetic field of the magnet, the magnet and the lifting ring can move upward under the repulsive effect of the magnetic field, so that the filter plate is lifted. When the magnetic rod leaves the magnetic field of the magnet, the lifting ring and the filter plate are reset downward. In this way, the filter plate vibrates up and down to prevent impurities and solid fat particles from blocking the sieve holes of the filter plate.

[0015] And the above scheme is divided into two cases:

[0016] Case 1: There is one magnetic rod and multiple magnets in a ring shape. In this case, when the magnetic rod approaches the magnet, due to the gap between the lifting ring and the extraction box, one side of the filter plate is lifted and the whole is tilted. In this case, the impurities and solid fat particles in the filter plate will roll or slide toward the middle of the filter plate.

[0017] Case 2: The magnetic rods and the magnets are in a one-to-one corresponding ring shape. In this case, when multiple magnetic rods are close to the magnet, the bottom of the lifting ring is driven by the magnetic force, and the lifting ring moves upward as a whole. Then when the magnetic force disappears, the lifting ring quickly returns to its position under the action of the first spring and its own gravity. Therefore, some impurities and solid fat particles inside the filter plate are suspended in the air due to the effect of weightlessness, thereby achieving the effect of separating the impurities and solid fat particles from the filter plate, and when the lifting ring is reset and collides with the flange, it can also generate vibration, further reducing the risk of clogging.

[0018] Preferably, the lower chamber has a main shaft inside, the bottom end of the magnetic rod is fixedly connected to the outer wall of the main shaft, the bottom of the main shaft is rotatably connected to the bottom of the extraction box, and the bottom of the main shaft is connected to a driving device, which is used to drive the main shaft to rotate.

[0019] Preferably, a protruding rod is provided on the upper surface of the middle part of the magnetic rod, a circle of protrusions is connected to the bottom of the filter plate, the top of the protruding rod is higher than the bottom of the protrusion, a hinge groove is provided in the middle part of the magnetic rod, the bottom of the protruding rod is hinged to the inside of the hinge groove, and a second spring is also connected between the bottom of the protruding rod and the bottom of the inner wall of the hinge groove, and the second spring keeps the protruding rod in a roughly vertical state, or in a completely vertical state. It should be noted that the roughly vertical state refers to a state in which the top of the protruding rod can contact the protrusion, that is, the protruding rod is allowed to tilt.

[0020] Preferably, an extension rod is connected to the outer wall of the convex rod, and when the convex rod is tilted by the convex block, the top end of the extension rod can abut against the bottom of the filter plate;

[0021] By setting the convex rod, when the main shaft drives the magnetic rod to rotate periodically, the convex rod abuts against the convex block at the bottom of the filter plate, thereby causing the bottom of the filter plate to vibrate, further reducing the risk of clogging of the screen holes.

[0022] Preferably, a driving gear is fixedly connected to the middle part of the main shaft, a movable sleeve is arranged around the main shaft, a fixed rod is fixedly connected to the bottom of the inner wall of the lower chamber, a sliding block is connected to the inner wall of the movable sleeve, an annular groove is provided on the outer wall of the fixed rod, the annular groove is wavy and arranged in a closed loop, and the sliding block is slidably connected to the annular groove.

[0023] Preferably, the outer wall of the movable sleeve is connected with a driven gear, and the driven gear is meshed with the driving gear;

[0024] By setting a driving gear and a driven gear, when the main shaft rotates, the driving gear drives the driven gear to rotate, and the gear drives the movable sleeve to rotate, so that the stirring blades around the movable sleeve stir the rapeseed oil, ensuring that the various substances in the rapeseed oil are evenly mixed, and the rapeseed oil is quickly discharged from the oil outlet;

[0025] Under the action of the annular groove and the sliding block, when the movable sleeve rotates, it can also slide up and down synchronously, so that the stirring blade can fully stir the rapeseed oil.

[0026] Preferably, follower plates (306) are provided at both ends of the convex rod (301), a vertical plate (307) is provided on the top of the follower plate (306), a hinge shaft (309) is connected to one end of the follower plate (306) close to the convex rod (301), a hinge hole (308) is provided in the middle of the convex rod (301), and the hinge shaft (309) is hinged to the hinge hole (308) by a torsion spring.

[0027] Compared with the prior art, the present invention provides a rapeseed oil efficient separation and extraction device, which has the following beneficial effects:

[0028] 1. The present invention drives the filter plate to move up and down through a driving device, so that the filter plate vibrates, so that when impurities or solid fat particles in the filter plate are filtered, the sieve holes on the filter plate are not easily blocked, thereby improving the filtering efficiency.

[0029] 2. The present invention uses the action of the first spring. When the power source for the up and down movement of the lifting ring and the filter plate is cut off, the lifting ring continues to exert a force on the first spring under the action of inertia and gravity, and the first spring generates a reaction force to continue to cause the lifting ring to move up and down, so that the up and down movement of the lifting ring continues for a short period of time, thereby allowing the blockage in the sieve holes on the filter plate to be detached.

[0030] 3. The present invention sets a driving gear and a driven gear. When the main shaft rotates, the driving gear drives the driven gear to rotate, and the gear drives the movable sleeve to rotate, so that the stirring blades around the movable sleeve stir the rapeseed oil, ensuring that the various substances in the rapeseed oil are evenly mixed, and the rapeseed oil is quickly discharged from the oil outlet.

[0031] 4. The present invention arranges a convex rod, a main shaft and a magnetic rod. When the main shaft drives the magnetic rod to rotate periodically, the convex rod can be abutted against the convex block at the bottom of the filter plate, thereby causing the bottom of the filter plate to vibrate, further reducing the risk of clogging of the screen holes.

DETAILED DESCRIPTION

[0043] See also Figure 1-Figure 10 This embodiment discloses a rapeseed oil efficient separation and extraction device, comprising an extraction box 100, wherein a filter plate 200 is disposed in the middle of the extraction box 100, and the filter plate 200 is used to filter impurities in the rapeseed oil;

[0044] The filter plate 200 divides the extraction box 100 into an upper chamber 101 and a lower chamber 102;

[0045] The inner wall of the extraction box 100 is connected with a flange 205, a lifting ring 201 is arranged above the flange 205, a limiting block 204 is connected around the bottom of the lifting ring 201, a limiting groove 206 is arranged around the flange 205, and the limiting block 204 is slidably connected to the limiting groove 206;

[0046] The top of the filter plate 200 is fixedly connected to the bottom of the limit block 204, and the lifting ring 201 can drive the filter plate 200 to reciprocate up and down under the action of the driving device;

[0047] The filter plate 200 is driven up and down by the driving device, so that the filter plate 200 vibrates, so that when the impurities or solid fat particles in the filter plate 200 are filtered, the sieve holes on the filter plate 200 are not easily blocked, thereby improving the filtering efficiency.

[0048] As a possible embodiment, the inner wall of the extraction box 100 is further connected with a guide sleeve 202, the bottom of the guide sleeve 202 extends to the inner side of the filter plate 200, and a first spring 203 is connected between the top of the lifting ring 201 and the top of the inner wall of the guide sleeve 202, and the first spring 203 presses the lifting ring 201 downward;

[0049] Through the action of the first spring 203, when the power source for the up and down movement of the lifting ring 201 and the filter plate 200 is cut off, under the action of inertia and gravity, the lifting ring 201 continues to apply a force to the first spring 203, and the first spring 203 generates a reaction force to continue to make the lifting ring 201 move up and down, so that the up and down movement of the lifting ring 201 continues for a short period of time, so that the blockage in the sieve holes on the filter plate 200 can be detached.

[0050] As a possible embodiment, a magnetic rod 208 is arranged inside the lower chamber 102, and the magnetic rod 208 has one or more, and the multiple magnetic rods 208 are symmetrically arranged along the central axis of the lower chamber 102. The bottom of the lifting ring 201 is connected to one or more magnets 207, and the multiple magnets 207 are symmetrically arranged along the central axis of the lifting ring 201. The bottom of the magnet 207 has the same magnetic pole as the top of the magnetic rod 208. When the top of the magnetic rod 208 is close to the magnetic field of the magnet 207, under the repulsion of like poles, the magnet 207 and the lifting ring 201 move upward synchronously.

[0051] As a possible embodiment, there is a gap between the limiting block 204 and the inner wall of the limiting groove 206, and there is a gap between the periphery of the lifting ring 201 and the inner wall of the extraction box 100;

[0052] By setting the magnetic rod 208 and the magnet 207, when the top of the magnetic rod 208 is close to the magnetic field of the magnet 207, the magnet 207 and the lifting ring 201 can move upward under the repulsive effect of the magnetic field, so that the filter plate 200 is lifted. When the magnetic rod 208 leaves the magnetic field of the magnet 207, the lifting ring 201 and the filter plate 200 are reset downward. In this reciprocating manner, the filter plate 200 vibrates up and down, thereby preventing impurities and solid fat particles from blocking the sieve holes of the filter plate 200.

[0053] And the above scheme is divided into two cases:

[0054] Case 1: There is one magnetic rod 208 and multiple magnets 207 are in a ring shape. In this case, when the magnetic rod 208 is close to the magnet 207, due to the gap between the periphery of the lifting ring 201 and the extraction box 100, one side of the filter plate 200 is lifted and the whole is tilted. In this case, the impurities and solid fat particles in the filter plate 200 will roll or slide toward the middle of the filter plate 200;

[0055] Case 2: The magnetic rods 208 and the magnets 207 are in a one-to-one corresponding ring shape. In this case, when multiple magnetic rods 208 are close to the magnet 207, the bottom of the lifting ring 201 is driven by the magnetic force, and the lifting ring 201 moves upward as a whole. Then when the magnetic force disappears, the lifting ring 201 quickly returns to its position downward under the action of the first spring 203 and its own gravity. Therefore, some impurities and solid fat particles inside the filter plate 200 are suspended in the air due to the effect of weightlessness, thereby achieving the effect of separating the impurities and solid fat particles from the filter plate 200, and when the lifting ring 201 is reset and collides with the flange 205, it can also generate vibration, further reducing the risk of clogging.

[0056] As a possible embodiment, the lower chamber 102 has a main shaft 209 inside, the bottom end of the magnetic rod 208 is fixedly connected to the outer wall of the main shaft 209, the bottom of the main shaft 209 is rotatably connected to the bottom of the extraction box 100, and the bottom of the main shaft 209 is connected to a driving device 210, and the driving device 210 is used to drive the main shaft 209 to rotate.

[0057] As a possible embodiment, a protruding rod 301 is provided on the middle upper surface of the magnetic rod 208, a circle of protrusions 305 are connected to the bottom of the filter plate 200, the top of the protruding rod 301 is higher than the bottom of the protrusion 305, a hinge groove 303 is opened in the middle of the magnetic rod 208, the bottom of the protruding rod 301 is hinged to the inside of the hinge groove 303, and a second spring 304 is connected between the bottom of the protruding rod 301 and the bottom of the inner wall of the hinge groove 303, the second spring 304 allows the protruding rod 301 to maintain a roughly vertical state, or a completely vertical state. It should be noted that the roughly vertical state refers to the state where the top of the protruding rod 301 can contact the protrusion 305, that is, the protruding rod 301 is allowed to tilt.

[0058] As a possible embodiment, the outer wall of the protruding rod 301 is connected with an extension rod 302. When the protruding rod 301 is tilted by the protruding block 305, the top of the extension rod 302 can abut against the bottom of the filter plate 200.

[0059] By setting the protruding rod 301, when the main shaft 209 drives the magnetic rod 208 to rotate periodically, when the protruding rod 301 abuts against the protruding block 305 at the bottom of the filter plate 200, the bottom of the filter plate 200 vibrates, further reducing the risk of sieve hole blockage, and the top of the extension rod 302 abuts against the bottom of the filter plate 200 to produce knocking, so that the blockage in the sieve hole can be knocked out. When the protruding rod 301 is separated from the protruding block 305, under the restoring action of the second spring 304, the protruding rod 301 returns to a vertical state;

[0060] It should be noted that although the filter plate 200 can move up and down, the range of its up and down movement is smaller than the thickness range of the protrusion 305. Therefore, the top of the protrusion 301 can always be higher than the bottom of the protrusion 305, so that the two can produce a counteracting effect.

[0061] As a possible embodiment, a driving gear 401 is fixedly connected to the middle of the main shaft 209, a movable sleeve 403 is arranged around the main shaft 209, a fixed rod 402 is fixedly connected to the bottom of the inner wall of the lower chamber 102, a sliding block 405 is connected to the inner wall of the movable sleeve 403, and an annular groove 404 is formed on the outer wall of the fixed rod 402, the annular groove 404 is wavy and closed-loop, and the sliding block 405 is slidably connected to the annular groove 404.

[0062] As a possible embodiment, the outer wall of the movable sleeve 403 is connected with a driven gear 407, and the driven gear 407 is meshed with the driving gear 401;

[0063] By providing a driving gear 401 and a driven gear 407, when the main shaft 209 rotates, the driving gear 401 drives the driven gear 407 to rotate, so that the gear 407 drives the movable sleeve 403 to rotate, so that the stirring blades 406 around the movable sleeve 403 stir the rapeseed oil, ensuring that the various substances in the rapeseed oil are evenly mixed, and the rapeseed oil is quickly discharged from the oil outlet 103;

[0064] Under the action of the annular groove 404 and the sliding block 405, when the movable sleeve 403 rotates, it can also slide up and down synchronously, so that the stirring blade 406 can fully stir the rapeseed oil.

[0065] As a possible embodiment, follower plates 306 are provided at both ends of the convex rod 301, a vertical plate 307 is provided on the top of the follower plate 306, an end of the follower plate 306 close to the convex rod 301 is connected to a hinge shaft 309, a hinge hole 308 is opened in the middle of the convex rod 301, and the hinge shaft 309 is hinged to the hinge hole 308 through a torsion spring (not shown in the figure);

[0066] By arranging follower plates 306 at both ends of the protruding rod 301 , the follower plates 306 can rotate together with the protruding rod 301 , so that the rapeseed oil can fall on the follower plates 306 instead of on the magnetic rod 208 , thereby preventing the rapeseed oil from accumulating on the magnetic rod 208 .
