Description

Technical Field

[0001] This utility model belongs to the field of pulverizing equipment, and more specifically, it relates to a xanthan gum grinding device. Background Technology

[0002] Xanthan gum grinding equipment is used to grind and process xanthan gum, a high-molecular-weight polysaccharide produced by microbial fermentation. It has unique rheological properties and thickening properties and is widely used in food, petroleum, pharmaceutical and other industries.

[0003] Chinese patent publication number "CN116099624A" discloses a raw material crushing device for xanthan gum fermentation, including a crushing tank. The bottom of the crushing tank is provided with a discharge port and a support frame. The crushing tank is provided with a grinding mechanism, which includes a fixed cylinder. Multiple grinding rings of the grinding mechanism form multiple grinding gaps, thereby effectively increasing the effective working area of ​​the crushing operation. Initially, the crushing is carried out by the grinding mechanism. Then, when the extrusion mechanism descends, it continuously extrudes and crushes the raw material. At the same time, the size of the space inserted by the extrusion ring into the grinding gap is used to further extrude the raw material.

[0004] During later use, the device also had the following problems: Adjusting the size of the gap between the extrusion ring and the grinding can adjust the grinding fineness and the particle size of the grinding powder. However, during the extrusion crushing process, the extrusion disc will continuously generate small axial vibrations, and the material will also exert axial reverse extrusion on the electric push rod, affecting the extension length of the electric telescopic rod. It is impossible to ensure that the grinding gap is at a constant width for a long time. If the grinding gap changes, it will directly affect the grinding effect of xanthan gum, resulting in inconsistent grinding particle size. Utility Model Content

[0010] Preferably, a limiting block is fixedly provided at the front of the adjusting rod, the limiting block is rotatably connected to the limiting cavity, a stud is fixedly provided at the rear of the limiting block, the stud is threadedly connected to the screw hole, a locking disc is fixedly provided at the rear of the stud, and an adjusting block is fixedly connected at the rear of the locking disc.

[0011] Preferably, the power mechanism includes a mounting frame, on which a drive motor is fixedly mounted. The front part of the mounting frame is fixedly connected to the fixed housing. A pulley is fixedly connected to the output shaft of the drive motor, and a transmission belt is mounted on pulley one and pulley two.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. By setting the grinding disc and adjusting the rotating rod, the distance the grinding disc extends forward can be adjusted, thereby changing the gap width between the grinding strip and the crushing rack, and thus adjusting the particle size of the material powder.

[0014] 2. By setting a locking mechanism, the adjusting rod is circumferentially locked to prevent the axial vibration generated by the grinding disc during grinding operations from causing the adjusting rod to loosen and rotate, which would make it difficult to ensure the uniformity of the particle size after the material is crushed and affect the crushing effect;

[0015] 3. As the equipment starts, the grinding disc rotates. The centrifugal force on the friction block is greater than the tension of the spring. At this time, the friction block extends outward from the slot and contacts the inner wall of the cavity. The friction between the two can reduce the axial vibration of the grinding disc to a certain extent and improve the stability of the gap width between the grinding disc and the end cover. When the equipment stops, the friction block retracts into the slot under the pull of the spring, making it easy to rotate the adjusting rod to adjust the width of the grinding gap.

[0031] The present invention will be further described below with reference to the accompanying drawings:

[0032] The directional terms used in the detailed description paragraphs are only for the convenience of those skilled in the art to understand the technical solutions described in this application based on the visual orientation shown in the accompanying drawings. Unless otherwise expressly specified and limited, the terms "setting," "installation," "connection," etc., should be interpreted broadly, and those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0033] like Figure 1 , Figure 3 , Figure 5 and Figure 6As shown, a xanthan gum grinding device includes a fixed housing 1, with a fixed support leg 101 fixedly connected to the bottom of the fixed housing 1. A slag outlet 102 is fixedly opened at the rear of the fixed housing 1. Incompletely ground xanthan gum material, due to its large particle size, cannot pass through the screen 103 and is discharged from the slag outlet 102 under the push of the brush plate 501. A power mechanism 3 is fixedly installed at the rear of the fixed housing 1, and a screen 103 is fixedly connected to the bottom of the fixed housing 1. Completely ground xanthan gum material passes through the screen 103 and is discharged. A fixed groove 104 is fixedly opened at the front of the fixed housing 1, and an end cap 2 is fixedly installed at the front of the fixed housing 1. Figure 4 As shown, a feed inlet 202 is fixedly opened in the middle of the end cover 2, and a hopper 201 is fixedly connected to the outside of the feed inlet 202. The xanthan gum material to be crushed is put into the hopper 201, enters the fixed housing 1 through the feed inlet 202 and contacts the grinding disc 5 for grinding. Multiple sets of grinding strips 203 are fixedly connected to the inner wall of the rear part of the end cover 2. The grinding strips 203 cooperate with the crushing rack 502 to crush the material. The crushing rack 502 has an arc design, so the material is crushed and pushed by the crushing rack 502 at the same time, so that the material can be quickly discharged from the center to the outside, improving the smoothness of the grinding operation.

[0034] A fixing protrusion 204 is fixedly connected to the side wall of the end cap 2. The fixing protrusion 204 cooperates with the fixing groove 104. The fixing protrusion 204 and the fixing groove 104 are fixed by bolts to complete the installation of the end cap 2 and the fixed housing 1. A mounting slot 105 is fixedly opened at the center of the rear part of the fixed housing 1, such as... Figure 7 and Figure 13 As shown, a transmission tube 4 is rotatably connected inside the mounting groove 105. A grinding disc 5 is installed inside the transmission tube 4. By setting the grinding disc 5 and adjusting the rotating rod 6, the forward extension distance of the grinding disc 5 is adjusted, thereby changing the gap width between the grinding strip 203 and the grinding rack 502, and adjusting the particle size of the material powder. An adjusting rotating rod 6 is installed inside the grinding disc 5. A locking mechanism 7 is fixedly installed at the rear of the transmission tube 4. By setting the locking mechanism 7, the adjusting rotating rod 6 is circumferentially locked, preventing the axial vibration generated by the grinding disc 5 during grinding operations from causing the adjusting rotating rod 6 to loosen and rotate, thus making it difficult to ensure the uniformity of the particle size after material crushing and affecting the crushing effect. A rotating opening 106 is fixedly installed at the front of the mounting groove 105.

[0035] like Figure 9 and Figure 10As shown, a pulley 401 is fixedly connected to the outer wall of the rear part of the transmission tube 4. The power mechanism 3 drives the pulley 401 to rotate via the transmission belt 304, and drives the grinding disc to rotate. The outer wall of the front part of the transmission tube 4 is rotatably connected to the mounting groove 105. A drive gear set 402 is fixedly provided on the inner wall of the front part of the transmission tube 4. The power of the transmission tube 4 is transmitted through the drive gear set 402 and the driven gear set 503A, driving the grinding disc to rotate. A cavity 403 is fixedly provided at the rear part of the drive gear set 402. A screw hole 404 is fixedly opened on the side wall of the rear part of the cavity 403. A locking cavity 405 is fixedly provided at the rear of the screw hole 404.

[0036] The locking mechanism 7 includes a compression spring 701, and a pressing plate 702 is fixedly connected to the rear of the compression spring 701. The rear of the pressing plate 702 and the front surface of the locking plate 603 are both provided with friction surfaces, so the coefficient of friction between them is large. Under the push of the compression spring 701, the pressing plate 702 and the locking plate 603 are tightly fitted together to perform circumferential locking operation on the adjusting rod 6 and prevent the adjusting rod 6 from rotating accidentally. The pressing plate 702 is slidably connected to the inner wall of the locking cavity 405, and the front end of the compression spring 701 is fixedly connected to the inner wall of the locking cavity 405.

[0037] like Figure 8 , Figure 11 and Figure 14 As shown, multiple sets of grinding racks 502 are fixedly connected to the front of the grinding disc 5. Brushes 501 are fixedly connected to the side wall of the grinding disc 5. The brushes 501 agitate the ground material, promote the material to pass quickly through the screen 103, and push the incompletely ground material backward toward the slag outlet 102. A drive column 503 is fixedly connected to the rear of the grinding disc 5. The outer wall of the front part of the drive column 503 slides in contact with the rotating port 106. A driven tooth assembly 503A is fixedly connected to the outer wall of the middle part of the drive column 503. 3A is circumferentially fixed to the drive gear set 402. Through their cooperation, the power of the power mechanism 3 is transmitted. A stabilizing ring 503B is fixedly connected to the outer wall of the rear part of the drive column 503. Multiple sets of slots 503D are fixedly opened on the outer wall of the stabilizing ring 503B. A tension spring 503E is fixedly connected to the bottom of the slot 503D. A friction block 503F is fixedly connected to the other end of the tension spring 503E. The friction block 503F is slidably connected to the slot 503D. A limit rotating cavity 503C is fixedly opened inside the drive column 503.

[0038] As the equipment starts, the grinding disc 5 rotates. The centrifugal force on the friction block 503F is greater than the tension of the tension spring 503E. At this time, the friction block 503F extends outward from the slot and contacts the inner wall of the cavity 403. The friction between the two can reduce the axial vibration of the grinding disc 5 to a certain extent and improve the stability of the gap width between the grinding disc 5 and the end cover 2. When the equipment stops, the friction block 503F retracts into the slot under the pull of the tension spring 503E, making it easy to rotate the adjusting rod 6 to adjust the width of the grinding gap.

[0039] like Figure 12 As shown, a limiting rotating block 601 is fixedly provided at the front of the adjusting rotating rod 6. The limiting rotating block 601 is rotatably connected to the limiting rotating cavity 503C. A stud 602 is fixedly provided at the rear of the limiting rotating block 601. The stud 602 is threadedly connected to the screw hole 404. A locking disc 603 is fixedly provided at the rear of the stud 602. An adjusting block 604 is fixedly connected to the rear of the locking disc 603. When it is necessary to adjust the grinding gap, the pressing disc 702 is pressed down so that it cannot contact the locking disc 603. Then, the adjusting block 604 is rotated with a tool. Since the stud 602 is screwed to the screw hole 404, the limiting rotating block 601 will push or pull the driving column 503, and the position of the grinding disc 5 is adjusted.

[0040] like Figure 2 As shown, the power mechanism 3 includes a mounting frame 301, on which a drive motor 302 is fixedly mounted. The front of the mounting frame 301 is fixedly connected to the fixed housing 1. A pulley 303 is fixedly connected to the output shaft of the drive motor 302. A transmission belt 304 is mounted on pulley 303 and pulley 401. The drive motor 302 drives pulley 303 to rotate, and pulley 303 drives pulley 401 to rotate via the transmission belt 304. The rotation of the transmission tube 4 is transmitted through the drive gear set 402 and the driven gear set 503A, driving the grinding disc 5 to rotate and perform grinding operations on the material.

[0041] Working principle:

[0042] 1. Start the drive motor 302, the grinding disc 5 rotates, and put the xanthan gum material to be crushed into the hopper 201. After crushing, the material falls onto the screen 103. With the agitation of the brush plate 501, the completely crushed material is discharged from the screen 103, and the incompletely crushed material is discharged from the slag outlet 102.

[0043] 2. When it is necessary to change the particle size of the material powder, turn off the drive motor 302 and wait for the grinding disc 5 to stop rotating completely;

[0044] 3. Push the locking mechanism 7 forward to disengage the extrusion disc 702 from the locking disc 603. Use a tool to rotate the adjusting block 604 to adjust the extension length of the grinding disc 5, thereby changing the grinding gap width and the particle size of the material.

[0045] 4. After adjustment, the extrusion plate 702 resumes contact with the locking plate 603 under the push of the compression spring 701, and the adjusting rod 6 is circumferentially locked again to prevent the adjusting rod 6 from being subjected to axial vibration of the grinding plate 5, which would cause the adjusting rod 6 to rotate unexpectedly, change the grinding gap width, and affect the grinding effect.

[0046] 5. During the rotation of the grinding disc 5, the multiple sets of friction blocks 503F on the stabilizing ring 503B come into contact with the inner wall of the cavity 403 under the action of centrifugal force, which can reduce part of the axial vibration of the grinding disc 5 and ensure the stability of the grinding gap.

[0047] This invention adjusts the distance the grinding disc 5 extends forward by setting a grinding disc 5 and an adjusting rod 6, thereby changing the gap width between the grinding strip 203 and the grinding rack 502 and adjusting the particle size of the material powder. By setting a locking mechanism 7, the adjusting rod 6 is circumferentially locked to prevent the axial vibration generated by the grinding disc 5 during grinding operations from causing the adjusting rod 6 to loosen and rotate, which would make it difficult to ensure the uniformity of the particle size after the material is crushed and affect the crushing effect.
