Description

Catalytic reaction device for xylanase and xylan Technical Field

[0001] The invention belongs to the technical field of catalytic reaction, and in particular relates to a catalytic reaction device of xylanase and xylan. Background Art

[0002] Xylan is a heterogeneous polysaccharide found in plant cell walls. During the production of xylan, it can be catalyzed by xylanase, breaking it down into xylooligosaccharides and xylose. During the catalytic reaction between xylanase and xylan, a stirring device is required to thoroughly mix the two to increase the reaction rate and improve product production efficiency.

[0003] However, existing catalytic reaction devices for xylanase and xylan often have the following technical problems:

[0004] 1. During the mixing process of xylanase and xylan, the storage device is often in a static state, which causes the raw materials of xylanase and xylan to easily adhere to the inner wall of the storage device, which not only reduces the output efficiency of the product, but also causes inconvenience to the subsequent cleaning work;

[0005] 2. When the xylanase and xylan are stirred, the raw materials tend to rotate along with the stirring rod, and the contact effect between them is reduced under the action of centrifugal force, thereby reducing the catalytic efficiency of the xylanase and xylan;

[0006] 3. During the stirring process of xylanase and xylan, the raw materials are easily deposited on the bottom wall of the device, resulting in poor catalytic effect of the xylanase and xylan deposited on the bottom wall of the device. Summary of the Invention

[0011] The lower wall of the support plate is provided with a swing mechanism for swinging the fixed sleeve and the storage barrel, the outer wall of the fixed sleeve is rotatably connected with a rotating mechanism for rotating the storage barrel, and the top of the feed box is provided with a lifting mechanism for assisting in unloading.

[0012] The gear train is connected with the gear of the driven gear and the gear is connected with the gear of the driven gear to form a circle around the gear of the driven gear.

[0013] Preferably, the stirring mechanism includes several stirring rods, several spoiler rods, annular gear grooves, several third gears and several spoiler blades, several stirring rods are fixedly connected to the stirring shaft, and each stirring rod is rotatably connected to a spoiler rod at one end away from the stirring shaft. An annular gear groove is fixedly connected to the inner wall of the storage barrel, and each spoiler rod is fixedly connected to a third gear on the side close to the annular gear groove. Each third gear is engaged with the annular gear groove, and each spoiler rod is fixedly connected to a plurality of spoiler blades at one end away from the annular gear groove.

[0014] Preferably, the rotating mechanism includes a rotating shaft, a fourth gear, a gear ring, a fifth gear and two second arc-shaped tooth grooves, the rotating shaft is rotatably connected to the side wall of the fixed sleeve, the fourth gear is fixedly connected to the rotating shaft, both sides of the storage barrel extend outside the fixed sleeve, and the side of the storage barrel close to the fourth gear is fixedly connected to the gear ring, the gear ring and the fourth gear are meshed with each other, and the fifth gear is also fixedly connected to the rotating shaft, two second arc-shaped tooth grooves are fixedly connected to the first arc-shaped tooth groove, and the two second arc-shaped tooth grooves are respectively meshed with the upper and lower parts of the fifth gear.

[0015] Preferably, the ejecting mechanism includes a push rod, an arc-shaped plate, two springs, a push ball, a U-shaped plate and an abutment wheel. The upper wall of the feed box is slidably connected with a push rod, the part of the push rod located above the feed box is fixedly connected with the arc-shaped plate, and the arc-shaped plate is elastically connected to the upper wall of the feed box through two springs. The part of the push rod located inside the feed box is fixedly connected with a push ball, the U-shaped plate is fixedly connected to the lower wall of the support plate, and the U-shaped plate is rotatably connected with the abutment wheel.

[0016] Preferably, a discharge port is provided below the fixed sleeve, and a baffle is provided at the discharge port.

[0017] Preferably, a sealing film is provided at the rotation connection between the fixed sleeve and the storage barrel.

[0018] Preferably, feeding channels are provided on both side walls of the feed box.

[0019] Compared with existing technologies, the advantages of the xylanase and xylan catalytic reaction device are:

[0020] 1. The present invention is provided with a swing mechanism. When the xylanase and xylan are stirred and the catalysis is accelerated, the rack is driven by the cylinder to perform reciprocating horizontal movement, and the fixed plate is further caused to swing back and forth through the first gear. The swing of the fixed plate will drive the storage barrel and the fixed sleeve to swing synchronously through the stirring shaft. At the same time, the stirring shaft is rotated under the action of the first arc-shaped tooth groove, so that while the stirring shaft stirs the xylanase and xylan, the storage barrel and the raw materials inside it are shaken left and right, which not only improves the catalytic effect, but also prevents the raw materials from sticking to the inner wall of the storage barrel when the storage barrel is in motion, thereby increasing the product output and facilitating subsequent cleaning work.

[0021] 2. The present invention provides a stirring mechanism. When the stirring shaft drives the stirring rod inside it to rotate, the spoiler rod on the stirring rod is driven to perform circular motion, and the spoiler rod is rotated synchronously under the action of the annular tooth groove and the third gear. As a result, the motion trajectory of the xylanase and xylan is disrupted when the xylanase and xylan are stirred, thereby avoiding the contact effect between the xylanase and xylan being reduced under the action of centrifugal force, and further improving the catalytic efficiency of the xylanase and xylan.

[0022] 3. The present invention provides a rotating mechanism. During the reciprocating swing of the fixed plate, the two second arcuate tooth grooves and the fifth gear can drive the rotating shaft to rotate, and the fourth gear can further drive the gear ring to rotate, so that the storage barrel rotates. The two second arcuate tooth grooves make the rotating shaft rotate in opposite directions when swinging to both sides, thereby causing the storage barrel to intermittently change its rotation direction during rotation, making it less likely for the raw materials to settle during the stirring process, making the catalytic reaction of xylanase and xylan more uniform and comprehensive. At the same time, the storage barrel with changed rotation direction can further disrupt the motion trajectory of xylanase and xylan during stirring, further improving the catalytic efficiency.

[0023] 4. The present invention provides a feeding mechanism, so that during the swinging of the fixed plate, the abutment wheel intermittently squeezes the arc plate, and the arc plate intermittently returns to its initial state under the elastic force of the spring, driving the push rod and the push ball to perform reciprocating vertical displacement, assisting the feeding of xylanase and xylan, and avoiding the blockage of raw materials at the feed port.

[0024] 5. The present invention only needs to set up one cylinder to drive the rack to move and make the fixed plate swing back and forth. The stirring rod can be rotated under the action of the first arc-shaped tooth groove, and the storage barrel can be rotated under the action of the second arc-shaped tooth groove, thereby avoiding the sedimentation of raw materials during the stirring process. In addition, the push ball can be driven to move back and forth vertically to avoid blockage of raw materials. The linkage between the various components is strong, and the required driving source is small, which saves costs and greatly improves work efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] The following examples are for illustrative purposes only and are not intended to limit the scope of the present invention.

[0035] As shown in Figures 1 to 8, a catalytic reaction device for xylanase and xylan comprises:

[0036] A support plate 1, a plurality of support legs 11 are fixedly connected to the lower wall of the support plate 1, a fixed sleeve 12 is provided on the lower wall of the support plate 1, a storage barrel 13 is rotatably connected to the inner wall of the fixed sleeve 12, a plurality of feed ports 14 are provided on the peripheral side wall of the storage barrel 13, a connecting port 15 is provided above the fixed sleeve 12, a feed box 16 is fixedly connected to the upper part of the fixed sleeve 12, and the feed box 16 is communicated with the interior of the storage barrel 13 through the connecting port 15 and the feed port 14;

[0037] The plurality of feed ports 14 allow the xylanase and xylan to intermittently enter the storage barrel 13 , thereby preventing excessive raw materials from entering the storage barrel 13 and causing difficulty in rotating the stirring rod 291 .

[0038] Among them, a discharge port is opened below the fixed sleeve 12, and a baffle is provided at the discharge port. The baffle can close the discharge port during work to prevent the leakage of raw materials, and the discharge port can be opened after the work is completed to take out the raw materials. This is a mature existing technology and will not be elaborated on here.

[0039] A sealing film is provided at the rotation connection between the fixed sleeve 12 and the storage barrel 13 , which can ensure that the storage barrel 13 rotates relative to the fixed sleeve 12 while preventing the raw materials from leaking out.

[0040] The two side walls of the feed box 16 are provided with feeding channels, to which feeding hoses can be fixedly connected for conveying xylanase and xylan, while ensuring that the swinging of the storage barrel 13 does not affect the conveying of raw materials.

[0041] The lower wall of the support plate 1 is provided with a swinging mechanism 2 for swinging the fixed sleeve 12 and the storage barrel 13, the outer wall of the fixed sleeve 12 is rotatably connected with a rotating mechanism 3 for rotating the storage barrel 13, and the top of the feed box 16 is provided with a lifting mechanism 4 for assisting unloading.

[0042] The swing mechanism 2 includes a rotating rod 21, a first gear 22, a cylinder 23, a rack 24, two fixed plates 25, a stirring shaft 26, a first arc-shaped tooth groove 27, a second gear 28 and a stirring mechanism 29. The rotating rod 21 is rotatably connected to the bottom of the support plate 1. The first gear 22 is fixedly connected to the rotating rod 21. The lower wall of the support plate 1 is fixedly connected to the cylinder 23. The output end of the cylinder 23 is fixedly connected to the rack 24. The first gear 22 and the rack 24 are meshed with each other. The rotating rod 21 is fixedly connected to the rack 24. There are two fixed plates 25 connected, and the bottom of the two fixed plates 25 is rotatably connected to a stirring shaft 26. The stirring shaft 26 passes through the storage barrel 13, and the stirring shaft 26 and the storage barrel 13 are coaxially arranged. The lower wall of the support plate 1 is fixedly connected to a first arc-shaped tooth groove 27, and the side of the stirring shaft 26 close to the first arc-shaped tooth groove 27 is fixedly connected to a second gear 28. The second gear 28 and the first arc-shaped tooth groove 27 are engaged with each other. The part of the stirring shaft 26 located in the storage barrel 13 is fixedly connected to a stirring mechanism 29.

[0043] In view of the problem that the storage device in the prior art is often in a static state, which causes the raw materials of xylanase and xylan to easily stick to the inner wall of the storage device, thereby reducing the product output efficiency, the present invention provides a swing mechanism 2. When the xylanase and xylan are stirred and the catalysis is accelerated, the rack 24 is driven by the cylinder 23 to move back and forth horizontally, and the fixed plate 25 is further made to swing back and forth through the first gear 22. The swing of the fixed plate 25 will drive the storage barrel 13 and the fixed sleeve 12 to swing synchronously through the stirring shaft 26. At the same time, the stirring shaft 26 is rotated under the action of the first arc-shaped tooth groove 27, so that while the stirring shaft 26 stirs the xylanase and xylan, the storage barrel 13 and the raw materials inside it are shaken left and right, which not only improves the catalytic effect, but also the storage barrel 13 in motion can prevent the raw materials from sticking to the inner wall of the storage barrel 13, thereby increasing the product output and facilitating subsequent cleaning work.

[0044] The stirring mechanism 29 includes several stirring rods 291, several spoiler rods 292, annular tooth grooves 293, several third gears 294 and several spoiler blades 295. The several stirring rods 291 are fixedly connected to the stirring shaft 26, and the end of each stirring rod 291 away from the stirring shaft 26 is rotatably connected to the spoiler rod 292. The inner wall of the storage barrel 13 is fixedly connected with an annular tooth groove 293. The side of each spoiler rod 292 close to the annular tooth groove 293 is fixedly connected to the third gear 294. Each third gear 294 is meshed with the annular tooth groove 293. The end of each spoiler rod 292 away from the annular tooth groove 293 is fixedly connected to several spoiler blades 295.

[0045] In order to solve the problem in the prior art that the raw materials are easily rotated along with the stirring rod, and the contact effect between them is reduced under the action of centrifugal force, thereby reducing the catalytic efficiency of xylanase and xylan, the present invention provides a stirring mechanism 29. When the stirring shaft 26 drives the stirring rod 291 inside it to rotate, the spoiler rod 292 on the stirring rod 291 is driven to perform circular motion, and the spoiler rod 292 is rotated synchronously under the action of the annular tooth groove 293 and the third gear 294. Then, when the xylanase and xylan are stirred, their motion trajectory is disturbed by the rotating spoiler blade 295, thereby avoiding the reduction of the contact effect between the xylanase and xylan under the action of centrifugal force, thereby further improving the catalytic efficiency of the xylanase and xylan.

[0046] The rotating mechanism 3 includes a rotating shaft 31, a fourth gear 32, a gear ring 33, a fifth gear 34 and two second arc-shaped tooth grooves 35. The rotating shaft 31 is rotatably connected to the side wall of the fixed sleeve 12. The fourth gear 32 is fixedly connected to the rotating shaft 31. Both sides of the storage barrel 13 extend outside the fixed sleeve 12, and the side of the storage barrel 13 close to the fourth gear 32 is fixedly connected to the gear ring 33. The gear ring 33 and the fourth gear 32 are meshed with each other. The fifth gear 34 is also fixedly connected to the rotating shaft 31. Two second arc-shaped tooth grooves 35 are fixedly connected to the first arc-shaped tooth groove 27. The two second arc-shaped tooth grooves 35 are respectively meshed with the upper and lower parts of the fifth gear 34.

[0047] In view of the problem in the prior art that raw materials are easily deposited on the bottom wall of the device, resulting in poor catalytic effect of xylanase and xylan deposited on the bottom wall of the device, the present invention provides a rotating mechanism 3. Since the first arcuate tooth groove 27 is fixed to the lower wall of the support plate 1, and the two second arcuate tooth grooves 35 are fixed on the first arcuate tooth groove 27, the positions of the first arcuate tooth groove 27 and the two second arcuate tooth grooves 35 are always fixed. During the reciprocating swing of the fixed plate 25, the rotating shaft 31 and the fifth gear 34 are always driven to move along the two second arcuate tooth grooves 35, and the fifth gear 34 cannot be engaged with the two second arcuate tooth grooves 35 at the same time. When the fixed plate 25 swings to the maximum When it is at the lowest position, it always meshes with one second arcuate tooth groove 35 first, and then meshes with the other second arcuate tooth groove 35. Therefore, the gear ring 33 can be driven to rotate by the fourth gear 32, so that the storage barrel 13 rotates. The two second arcuate tooth grooves 35 make the rotating shaft 31 rotate in opposite directions when swinging to both sides, thereby causing the storage barrel 13 to intermittently change its rotation direction during rotation, making it less likely for the raw materials to settle during the stirring process, making the catalytic reaction of xylanase and xylan more uniform and comprehensive. At the same time, the storage barrel 13 with a changed rotation direction can further disrupt the motion trajectory of xylanase and xylan during stirring, further improving the catalytic efficiency.

[0048] The ejecting mechanism 4 includes a push rod 41, an arc-shaped plate 42, two springs 43, a push ball 44, a U-shaped plate 45 and an abutment wheel 46. The upper wall of the feed box 16 is slidably connected with the push rod 41, and the part of the push rod 41 located above the feed box 16 is fixedly connected to the arc-shaped plate 42. The arc-shaped plate 42 is elastically connected to the upper wall of the feed box 16 through two springs 43. The part of the push rod 41 located inside the feed box 16 is fixedly connected to the push ball 44, the U-shaped plate 45 is fixedly connected to the lower wall of the support plate 1, and the abutment wheel 46 is rotatably connected to the U-shaped plate 45.

[0049] In order to solve the problem that the raw materials in the above-mentioned device may be blocked during the process of entering the feed box 16, the fixed sleeve 12 and the storage barrel 13, the present invention sets a top-feeding mechanism 4, which drives the curved plate 42 on the top of the feed box 16 to swing left and right during the swinging of the fixed plate 25. Since the position of the abutment wheel 46 remains unchanged, no matter whether the curved plate 42 swings to the left or right, the curved plate 42 will deviate from the abutment wheel 46, and further the curved plate 46 will no longer squeeze the curved plate 42. Therefore, during the swinging of the fixed plate 25 and the curved plate 42 left and right, the abutment wheel 46 intermittently squeezes the curved plate 42, and the curved plate 42 intermittently returns to its initial state under the elastic force of the spring 43, driving the push rod 41 and the push ball 44 to perform reciprocating vertical displacement, thereby assisting the discharge of xylanase and xylan, and avoiding the blockage of raw materials at the feed port 14.

[0050] In addition, the present invention only needs to set up one cylinder 23 to drive the rack 24 to move and make the fixed plate 25 swing back and forth. The stirring rod 291 can be rotated under the action of the first arc-shaped tooth groove 27, and the storage barrel 13 can be rotated under the action of the second arc-shaped tooth groove 35, thereby avoiding the sedimentation of raw materials during the stirring process. In addition, it can also drive the push ball 44 to move back and forth vertically to avoid blockage of raw materials. The linkage between the various components is strong, and the required driving source is small, which saves costs and greatly improves work efficiency.

[0051] The present invention can be explained through the following operation mode:

[0052] During use, the xylanase and xylan are respectively delivered to the feed box 16 through the two feeding channels, and then the cylinder 23 is turned on. The reciprocating movement of the rack 24 drives the first gear 22 and the two fixed plates 25 to swing back and forth, thereby causing the storage barrel 13 and the fixed sleeve 12 to swing synchronously. At the same time, the stirring shaft 26 is rotated under the action of the first arc-shaped tooth groove 27. Therefore, while the stirring shaft 26 stirs the xylanase and xylan, the storage barrel 13 and the raw materials therein are shaken left and right, which not only improves the catalytic effect, but also prevents the raw materials from adhering to the inner wall of the storage barrel 13 when the storage barrel 13 is in motion.

[0053] During the rotation of the stirring shaft 26, the spoiler rod 292 on the stirring rod 291 is driven to perform circular motion, and the spoiler rod 292 is rotated synchronously under the action of the annular tooth groove 293 and the third gear 294, and the motion trajectory of the spoiler rod 292 is disrupted by the rotating spoiler blade 295, thereby preventing the contact effect between the xylanase and the xylan from being reduced due to the action of centrifugal force;

[0054] During the reciprocating swing of the fixed plate 25, the rotating shaft 31 can be driven to rotate by the two second arc-shaped tooth grooves 35 and the fifth gear 34, and the gear ring 33 can be further driven to rotate by the fourth gear 32, so that the storage barrel 13 rotates. The two second arc-shaped tooth grooves 35 make the rotating shaft 31 rotate in opposite directions when swinging to both sides, so that the storage barrel 13 intermittently changes the rotation direction during rotation, making it less likely for the raw materials to settle during the stirring process, making the catalytic reaction of xylanase and xylan more uniform and comprehensive, and at the same time, the storage barrel 13 with changed rotation direction can further disrupt the motion trajectory of xylanase and xylan during stirring.

[0055] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
