Description

Technical Field

[0001] The invention relates to the technical field of silicon carbide slurry production, in particular to a silicon carbide slurry storage and transfer device. Background Art

[0002] Silicon carbide slurry is a suspension of silicon carbide powder mixed with a liquid medium (such as water or organic solvent) and additives. This slurry is widely used in many industrial fields. Usually, silicon carbide slurry is mass-produced in a processing workshop, and then distributed according to the actual needs of each production line and transported using storage and transfer equipment.

[0003] A Chinese patent with publication number CN116588527B proposes a constant temperature and moisture-keeping graphene slurry automatic storage device, in which four rotating shafts arranged in a matrix are arranged in a storage barrel, and the four rotating shafts are connected by a conveyor belt transmission. The conveyor belt is hinged with arc-shaped flaps evenly arranged along its outer ring surface. The graphene slurry in the storage barrel is flipped up and down by the cooperation of the conveyor belt and the arc-shaped flap. At the same time, the conveyor belt pushes the stirring blades on the stirring shaft to rotate around the stirring shaft through the pushing bar during the movement. The stirring blades stir the graphene slurry during the rotation to prevent the graphene slurry in the storage barrel from sedimentation.

[0004] However, the above-mentioned automatic storage device still has the following problems when in use: 1. The components for turning the slurry, such as the conveyor belt and the arc-shaped flap, occupy a large space inside the storage barrel, which directly affects the storage capacity of the storage barrel for the slurry, and is also easy to hinder the discharge of the slurry, affecting the discharge efficiency; 2. At the same time, graphene slurry will adhere to the surfaces of many components in the storage barrel, which will affect the actual usable amount of graphene slurry. At the same time, because the components in the storage barrel cannot be disassembled from the storage barrel and occupy a large space, it is not convenient to clean, which will affect the subsequent reuse of the storage device; 3. The arc-shaped flap only has a connection force point between the conveyor belts, and its stability during movement is insufficient, which will affect the mixing effect and the service life of the device.

[0019] 3. The present invention supports the slot frame through the linkage of the support plate, the tension spring and the baffle plate. When the round rod drives the slot frame to move upward, the tension of the tension spring is used to drive the support plate to move upward, so that the support plate always provides auxiliary support to the slot frame, thereby improving the stability of the slot frame and facilitating the round rod to drive the slot frame and the lifting rod to move up and down stably.

[0020] 4. The integral structure with multi-directional stirring and mixing and inner wall scraping functions in the present invention occupies a small space, has a simple structure, and is easy to disassemble as a whole. When the interior of the storage tank and the stirring mechanism need to be cleaned, the stirring mechanism can be taken out from the interior of the storage tank and cleaned quickly separately to avoid dead corners for cleaning. The cleaning is more convenient and facilitates subsequent use. BRIEF DESCRIPTION OF THE DRAWINGS

However, the present invention can be implemented in many other ways different from those described below, and those skilled in the art can make similar improvements without violating the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.

[0032] See also Figure 1 and Figure 2 A silicon carbide slurry storage and transfer device comprises a storage tank 1 and a tank cover 2 detachably mounted on the top of the storage tank 1, a feed port is arranged on the tank cover 2, a stirring mechanism 3 is rotatably mounted on the bottom of the tank cover 2, a driving motor 4 for driving the stirring mechanism 3 to rotate is mounted on the top of the tank cover 2, a limiting mechanism 6 for guiding and limiting the tank cover 2 is mounted on the storage tank 1, and a plurality of discharge ports 11 are evenly mounted on the bottom of the storage tank 1 in a circumferential direction.

[0033] See also Figure 1 , Figure 2 and Figure 3 The stirring mechanism 3 includes a crossbeam 31 rotatably mounted on the bottom of the tank cover 2, a left-right symmetrical wave-shaped rotating rod 32 is fixedly connected to the bottom of the crossbeam 31, a lower scraper 33 is commonly connected to the bottom of the left and right two wave-shaped rotating rods 32, a left-right symmetrical support rod 34 located on the opposite side of the wave-shaped rotating rod 32 is fixedly connected between the crossbeam 31 and the lower scraper 33, a front side of the support rod 34 is rotatably connected to a plurality of elastic telescopic rods 35 equidistantly distributed up and down through a rotating shaft, an end of the elastic telescopic rod 35 close to the wave-shaped rotating rod 32 is hinged with a movable sleeve 36 sleeved on the outside of the wave-shaped rotating rod 32, an end of the elastic telescopic rod 35 away from the wave-shaped rotating rod 32 is a telescopic section, and the ends of the telescopic sections of the plurality of elastic telescopic rods 35 corresponding to the same support rod 34 are commonly hinged with a side scraper 37.

[0034] See also Figure 1 , Figure 2 and Figure 3 A lifting mechanism 5 is installed on the crossbeam 31 to drive the uppermost elastic telescopic rod 35 to reciprocate up and down around the corresponding rotating shaft, and the lifting mechanism 5 is arranged symmetrically.

[0035] See also Figure 1 , Figure 2 and Figure 3The wavy rotating rod 32 is composed of a plurality of arc-shaped rods with circular cross-sections connected end to end, and the center of the arc-shaped rod is far away from the central axis of the storage tank 1. The rotating shaft connected to the elastic telescopic rod 35 is coaxial with the arc-shaped rod. The movable sleeve 36 is sleeved on the arc-shaped circular rod. The left and right wavy rotating rods 32 are connected by a connecting rod. The connecting rod is located at the end of the arc-shaped rod and will not affect the movement of the movable sleeve 36. The bottom end of the output shaft of the driving motor 4 rotates to pass through the bottom of the tank cover 2 and is fixedly connected to the top of the crossbeam 31. The output shaft of the driving motor 4 is fixedly connected with an indicator plate 41 located above the tank cover 2. An indicator hole is provided on the indicator plate 41 and the indicator plate 41 is parallel to the crossbeam 31. A positioning hole aligned with the indicator hole is provided on the top of the tank cover 2.

[0036] When the slurry needs to be stirred, the driving motor 4 drives the cross beam 31, the wavy rotating rod 32, the lower scraper 33 and the support rod 34 to rotate, so that the wavy rotating rod 32 and the lower scraper 33 stir the slurry. When the support rod 34 rotates, it will drive the elastic telescopic rod 35 and the side scraper 37 to rotate, so that the elastic telescopic rod 35 and the side scraper 37 stir the slurry. During the stirring process, the lower scraper 33 and the side scraper 37 can respectively scrape the slurry on the inner bottom wall and the inner ring wall of the storage tank 1 to prevent the slurry from adhering to the storage tank 1.

[0037] See also Figure 2 , Figure 3 , Figure 4 and Fig. 9 The lifting mechanism 5 includes a lifting rod 51 that is slidably installed on the beam 31 up and down. The bottom end of the lifting rod 51 passes through the bottom of the beam 31 and is rotatably connected to a sliding sleeve 52. The sliding sleeve 52 is slidably sleeved on the outside of the end of the top elastic telescopic rod 35 away from the side scraper 37. The sliding sleeve 52 is located between the corresponding rotating shaft and the movable sleeve 36. A lifting component 53 that drives the lifting rod 51 to move up and down is installed on the top of the beam 31, and a strengthening component 54 is also installed between the lifting rod 51 and the elastic telescopic rod 35.

[0038] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 and Fig. 9 The lifting assembly 53 includes a turntable 531 rotatably mounted on the top of the beam 31 through a bracket, the turntable 531 is rotatably connected to a round rod 532 at the edge of the turntable 531 close to the corresponding lifting rod 51, the top of the lifting rod 51 passes through the top of the beam 31 and is fixedly connected to a groove frame 533, the round rod 532 is slidably mounted inside the groove frame 533, the bottom of the tank cover 2 is fixedly connected to a gear ring 534 whose center coincides with the axis of the driving motor 4, the outer ring wall of the turntable 531 is provided with teeth, and the teeth on the turntable 531 are meshed with the gear ring 534.

[0039] When the lifting assembly 53 is driven to rotate by the cross beam 31, the turntable 531 is driven to rotate by the gear ring 534, and then the turntable 531 drives the round rod 532 to rotate, and the round rod 532 is used to drive the slot frame 533 and the lifting rod 51 to move back and forth up and down. When the slot frame 533 moves up and down, the round rod 532 will slide back and forth inside the slot frame 533, and the lifting rod 51 is used to pull the end of the elastic telescopic rod 35 close to the center of the storage tank 1 to swing up and down, and the elastic telescopic rod 35 deflects around the rotating shaft to which it is connected. When the elastic telescopic rod 35 swings up and down, the sliding sleeve 52 will slide left and right along the elastic telescopic rod 35, and the elastic telescopic rod 35 revolves circumferentially with the cross beam 31 to implement circumferential stirring while also swinging by itself. During the swinging process, the slurry can be stirred up and down, and the mixed slurry is fully stirred to avoid slurry sedimentation. At the same time, the elastic telescopic rod 35 is used to drive the movable sleeve 36 and the side scraper 37 to move up and down. The movable sleeve 36 moves up and down along the wavy rotating rod 32, and can scrape off the slurry on the wavy rotating rod 32. At the same time, the movable sleeve 36 and the wavy rotating rod 32 cooperate to provide a force point for the elastic telescopic rod 35, thereby improving the stability of the elastic telescopic rod 35 in rotating and stirring. During the rotation, the side scraper 37 moves up and down along the inner wall of the storage tank 1, and can scrape off the slurry on the inner ring wall of the storage tank 1, thereby reducing the adhesion of raw materials on the inner ring wall of the storage tank 1; and when discharging, the swinging elastic telescopic rod 35 can throw off the slurry adhered to itself.

[0040] See also Figure 3 and Figure 4 The strengthening component 54 includes a slide groove 541 opened at the top of the fixed section of the elastic telescopic rod 35, and a slider 542 is installed inside the slide groove 541 for sliding left and right. The slider 542 is located on the side of the sliding sleeve 52 away from the corresponding movable sleeve 36. The top of the slider 542 is rotatably connected to a pull rod 543, and the end of the pull rod 543 away from the corresponding slider 542 is rotatably connected to the outer ring wall of the lifting rod 51.

[0041] When the lifting rod 51 pulls the elastic telescopic rod 35 to move up and down, the slider 542 will slide left and right along the slide groove 541, and the pull rod 543 can share the pulling force between the sliding sleeve 52 and the lifting rod 51, thereby improving the firmness when the lifting rod 51 pulls the elastic telescopic rod 35 to move up and down. A triangular structure is always formed among the pull rod 543, the elastic telescopic rod 35 and the lifting rod 51, and the overall structural strength is improved to a certain extent.

[0042] See also Figure 2 , Figure 4 , Figure 5 , Figure 6 and Figure 8The limiting mechanism 6 includes an outer arc plate 61 fixedly mounted on the inner wall of the storage tank 1 and symmetrical in front and back, a left-right symmetrical arc-shaped limiting block 62 is slidably mounted on the bottom of the outer arc plate 61 along the arc direction, a moving component 63 is mounted on the outer arc plate 61 to drive the corresponding arc-shaped limiting block 62 to slide, an inner arc plate 64 co-centric with the inner arc plate 61 is fixedly connected to the inner side of the outer arc plate 61 through a connecting plate, an arc frame 65 co-centric with the inner arc plate 64 is fixedly connected to the inner ring wall, and a support plate 6 is slidably mounted on the inner ring wall of the arc frame 65 up and down 6. The groove frame 533 abuts against the top of the support plate 66. A tension spring 67 is fixedly connected between the top of the support plate 66 and the top of the arc frame 65. The tension spring 67 is not on the circumferential revolution path of the groove frame 533. A left-right symmetrical baffle 68 is installed on the top of the arc frame 65 for sliding along its radial direction. A moving component 2 69 for driving the baffle 68 to slide is installed on the outer ring wall of the arc frame 65. The widths of the cross beam 31, the lower scraper 33 and the side scraper 37 are equal, and the spacing between the front and rear outer arc plates 61 is equal to the width of the cross beam 31.

[0043] See also Figure 2 , Figure 5 , Figure 6 , Figure 7 and Fig. 9 The outer ring wall and the inner ring wall of the arc-shaped limit block 62 are both provided with inclined surfaces, and the bottom ends of the inclined surfaces are inclined toward the direction close to the center of the storage tank 1. The moving component 63 includes a wedge block 631 fixedly connected to the top of the arc-shaped limit block 62. A through groove for the corresponding wedge block 631 to slide is opened on the outer arc plate 61. A return spring 632 is fixedly connected between one side of the wedge block 631 close to the end of the outer arc plate 61 and the inner wall of the through groove. A plurality of pressure blocks 633 located above the wedge block 631 are evenly installed circumferentially on the inner ring wall of the tank cover 2, and the pressure block 633 cooperates with the corresponding wedge block 631.

[0044] In the initial state, the rebound force of the reset spring 632 is used to push the wedge block 631 and the arc limit block 62 to move in the opposite direction away from the beam 31. At this time, the two arc limit blocks 62 on the same outer arc plate 61 are in conflict with each other at one end away from the beam 31, and the distance between the two corresponding ends of the front and rear arc limit blocks 62 is equal to the width of the beam 31. The beam 31, the lower scraper 33 and the side scraper 37 are placed in the storage tank 1 through the gap between the front and rear arc limit blocks 62.

[0045] In the process of closing the tank cover 2 on the top of the storage tank 1, the pressing block 633 first conflicts with the inclined surface of the wedge block 631, and the pressing block 633 is used to push the inclined surface of the corresponding wedge block 631 downward, so that the wedge block 631 drives the arc limit block 62 to move toward the direction close to the cross beam 31, so that the four arc limit blocks 62 are evenly distributed. At this time, the distance between the ends of the two adjacent arc limit blocks 62 is equal to half the width of the cross beam 31. When the tank cover 2 is completely closed with the storage tank 1, the end of the cross beam 31 conflicts with the inclined surface inside the arc limit block 62, and the inclined surface inside the arc limit block 62 is used to support and guide the cross beam 31, thereby improving the stability of the cross beam 31 when rotating.

[0046] See also Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 A limit block 371 is installed on the top of the side scraper 37 for sliding up and down. A protrusion 372 is fixedly connected to the side of the limit block 371 away from the center of the storage tank 1. A step groove is provided on the inner ring wall of the storage tank 1, and the protrusion 372 is slidably installed on the step groove. The top of the limit block 371 is an inclined surface that slides with the outer inclined surface of the arc-shaped limit block 62. A movable rod 373 is fixedly connected to the bottom of the limit block 371. The bottom end of the movable rod 373 is slidably connected to the inside of the side scraper 37. A compression spring 374 mounted on the outside of the movable rod 373 is fixedly connected between the bottom end of the movable rod 373 and the inner wall of the side scraper 37.

[0047] After the side scraper 37 is completely placed into the storage tank 1, the protrusion 372 is just pressed against the stepped groove, and then as the arc-shaped limit block 62 moves toward the direction close to the cross beam 31, the outer inclined surface of the arc-shaped limit block 62 is pressed against the limit block 371, and the arc-shaped limit block 62 and the stepped groove are used to limit and guide the limit block 371, thereby improving the stability of the limit block 371 and the side scraper 37 during rotation.

[0048] When the elastic telescopic rod 35 drives the side scraper 37 to move downward, the protrusion 372 is blocked by the stepped groove and will not move downward, and the compression spring 374 will be compressed. When the elastic telescopic rod 35 drives the side scraper 37 to move upward, the rebound force of the compression spring 374 can assist in pushing the side scraper 37 to move upward.

[0049] See also Figure 2 , Figure 3 , Figure 5 and Figure 6The rear inner arc plate 64 is provided with an arc-shaped through groove 641 which is symmetrical from left to right and runs through from top to bottom, and the front side of the arc-shaped through groove 641 is open. The arc-shaped through groove 641 is plugged into the support rod 34. The bottom of the inner arc plate 64 is provided with a guide groove 642 which is located below the arc-shaped through groove 641 and connected to the arc-shaped through groove 641, and the top of the support rod 34 is slidably matched with the guide groove 642.

[0050] When the lower scraper 33 and the support rod 34 are placed into the storage tank 1, the support rod 34 passes through the arc-shaped through groove 641. When the support rod 34 is completely placed into the storage tank 1, the top of the support rod 34 is just in the guide groove 642. When the cross beam 31 drives the support rod 34 to rotate, the guide groove 642 can guide and limit the top of the support rod 34, thereby improving the stability of the cross beam 31 and the support rod 34 during rotation.

[0051] When the cross beam 31 and the support rod 34 are taken out from the storage tank 1, the indicator hole on the indicator plate 41 is aligned with the positioning hole on the top of the tank cover 2 (the indicator hole and the positioning hole can be completely aligned up and down by inserting a positioning pin. If they are not aligned, the driving motor 4 is driven to rotate for fine adjustment). At this time, the cross beam 31 is aligned with the gap between the front and rear outer arc plates 61, and the support rod 34 is aligned with the corresponding arc groove 641. When the support rod 34 moves upward, the arc groove 641 is used to scrape off the slurry adhered to the surface of the support rod 34. At the same time, the arc limit block 62 can scrape off the slurry on the surface of the side scraper 37, thereby reducing the waste of slurry and facilitating subsequent cleaning.

[0052] See also Figure 2 , Figure 4 , Figure 5 , Figure 8 and Fig. 9 The moving component 69 includes a guide frame 691 which is fixedly connected to the outer ring wall of the arc frame 65 and is symmetrical on both sides. A wedge block 692 is fixedly connected to the side of the baffle 68 away from the center of the arc frame 65. The wedge block 692 is slidably installed on the top of the guide frame 691. A return spring 693 is fixedly connected between the side of the wedge block 692 close to the center of the arc frame 65 and the inner wall of the guide frame 691. A plurality of pressure blocks 694 located above the wedge blocks 692 are evenly installed on the bottom circumference of the tank cover 2. The pressure blocks 694 cooperate with the corresponding wedge blocks 692.

[0053] In the process of closing the tank cover 2 on the top of the storage tank 1, the pressure block 694 first contacts the inclined surface of the wedge block 692, and the pressure block 694 pushes the inclined surface of the wedge block 692 downward, so that the wedge block 692 pushes the baffle 68 to move toward the center of the storage tank 1, so that the baffle 68 is blocked at the top of the slot frame 533. During the up and down movement of the slot frame 533, the support plate 66 is always pressed against the slot frame 533 under the action of the tension spring 67. The support plate 66 can play a certain supporting role on the slot frame 533, thereby improving the stability of the up and down movement of the slot frame 533.

[0054] See also Figure 1-Figure 9 When used specifically, step one, in the initial state, utilize the resilience of the reset spring 632 to push the wedge block 631 and the arc limit block 62 to move in the opposite direction away from the beam 31. At this time, the two arc limit blocks 62 on the same outer arc plate 61, at one end away from the beam 31, collide with each other, and the end of the arc limit block 62 close to the beam 31 is aligned with the end of the outer arc plate 61 close to the beam 31. The distance between the two corresponding arc limit blocks 62 is equal to the width of the beam 31.

[0055] Step 2: Install the stirring mechanism 3 into the storage tank 1. During installation, the cross beam 31, the lower scraper 33 and the side scraper 37 are aligned with the gap between the front and rear outer arc plates 61, and the support rod 34 is aligned with the corresponding arc-shaped through groove 641. When the cross beam 31 completely enters the storage tank 1, the top of the support rod 34 is just in the guide groove 642. At this time, the cross beam 31 is located below the outer arc plate 61, and the protrusion 372 is just pressed against the step groove.

[0056] Step 3: In the process of closing the tank cover 2 onto the top of the storage tank 1, the pressing block 1 633 first conflicts with the inclined surface of the wedge block 1 631, and the pressing block 2 694 conflicts with the inclined surface of the wedge block 2 692. The pressing block 1 633 pushes the inclined surface of the corresponding wedge block 1 631 downward, so that the wedge block 1 631 drives the arc-shaped limit block 62 to move toward the direction close to the crossbeam 31, so that the four arc-shaped limit blocks 62 are evenly distributed. At this time, the distance between two adjacent arc-shaped limit blocks 62 is equal to The outer arc plate 61 is used to support and guide the cross beam 31, and the outer inclined surface of the arc limit block 62 is pressed against the limit block 371. The arc limit block 62 and the stepped groove are used to limit and guide the limit block 371. At the same time, the pressure block 694 is used to push the inclined surface of the wedge block 692 downward, so that the wedge block 692 pushes the baffle 68 to move toward the center of the storage tank 1, so that the baffle 68 is blocked at the top of the slot frame 533.

[0057] Step 4, fix the tank cover 2 and the storage tank 1 together, and drive the cross beam 31, the wavy rotating rod 32, the lower scraper 33 and the support rod 34 to rotate through the driving motor 4, so that the wavy rotating rod 32 and the lower scraper 33 stir the slurry, and when the support rod 34 rotates, it will drive the elastic telescopic rod 35 and the side scraper 37 to rotate, so that the elastic telescopic rod 35 and the side scraper 37 stir the slurry. During the stirring process, the lower scraper 33 and the side scraper 37 can scrape the slurry on the inner bottom wall and the inner ring wall of the storage tank 1 respectively.

[0058] Step 5. During the rotation of the cross beam 31, the gear ring 534 drives the turntable 531 to rotate, and the turntable 531 drives the round rod 532 to rotate. The round rod 532 drives the slot frame 533 and the lifting rod 51 to move back and forth up and down. During the up and down movement of the slot frame 533, the round rod 532 will slide back and forth inside the slot frame 533. The lifting rod 51 is used to pull the end of the elastic telescopic rod 35 close to the center of the storage tank 1 to swing up and down. During the up and down swinging of the elastic telescopic rod 35, the sliding sleeve 52 will slide left and right along the elastic telescopic rod 35, and the elastic telescopic rod 35 can stir the slurry up and down during the swinging process.

[0059] Step six, when discharging is required, open the discharging port 11 to discharge the slurry. There are multiple discharging ports 11 for discharging at the same time. During the discharging process, the cross beam 31, the wavy rotating rod 32 and the lower scraper 33 keep rotating, and the elastic telescopic rod 35 swinging up and down can shake off the slurry adhered to the surface. At the same time, the elastic telescopic rod 35 is used to drive the movable sleeve 36 and the side scraper 37 to move up and down. The movable sleeve 36 moves up and down along the wavy rotating rod 32 to scrape off the slurry on the wavy rotating rod 32. The side scraper 37 moves up and down along the inner wall of the storage tank 1 to scrape off the slurry on the inner ring wall of the storage tank 1. The lower scraper 33 can scrape off the slurry on the inner bottom wall of the storage tank 1 to reduce the adhesion of raw materials on the inner wall of the storage tank 1.

[0060] Step seven, when the slurry in the storage tank 1 is completely discharged, open the tank cover 2 and take out the stirring mechanism 3 from the storage tank 1. When the tank cover 2 is separated from the storage tank 1, the pressing block 633 no longer pushes the wedge block 631, and the rebound force of the return spring 632 is used to push the wedge block 631 and the arc limit block 62 to move in the opposite direction away from the beam 31, so that the end of the arc limit block 62 close to the beam 31 is aligned with the end of the outer arc plate 61 close to the beam 31. At the same time, the pressing block 694 no longer pushes the inclined surface of the return spring 693, and the rebound force of the wedge block 692 is used to push the return spring 693 and the baffle 68 to move away from the center of the storage tank 1, so that the baffle 68 no longer blocks the groove frame 533.

[0061] Step eight, align the indicating hole on the indicating plate 41 with the positioning hole on the top of the tank cover 2. At this time, the cross beam 31 is aligned with the gap between the front and rear outer arc plates 61, and the support rod 34 is aligned with the corresponding arc groove 641. When the support rod 34 moves upward, the arc groove 641 is used to scrape off the slurry adhered to the surface of the support rod 34. At the same time, the arc limit block 62 can scrape off the slurry on the surface of the side scraper 37, reducing the waste of slurry and facilitating subsequent cleaning.
