Description

Technical Field

[0001] This invention relates to the field of mica product manufacturing technology, and more specifically, to a composite stirring mica pulp preparation and processing device. Background Technology

[0002] The preparation process of mica paper includes: crushing, grading, pulping, papermaking and forming, pressing, drying, and winding. Among them, the pulping process often adopts the acid pulping process, which involves impregnating mica cadmium in 2-5% dilute acid (sulfuric acid, hydrochloric acid, or phosphoric acid) and heating it to form pulp, which is then washed, graded, and dehydrated.

[0003] The utility model with announcement number CN223454248U discloses a mica pulp mixing device, including a reaction vessel, a stirring shaft, an impeller, and an outer casing. The outer casing includes a tube body and a gas collecting hood located below the tube body. The gas collecting hood has several through holes. The stirring shaft is inserted into the tube body. The impeller is rotatably connected to the bottom of the reaction vessel inside the gas collecting hood. A vent pipe is provided at the bottom of the reaction vessel. The vent pipe is connected to a steam source. The outlet of the vent pipe is located below the gas collecting hood. There is a gap between the stirring shaft and the tube body. Through the gap, the pulp can be squeezed, kneaded, and dispersed.

[0004] While this device can squeeze, knead, and disperse slurry through gaps, traditional mixing often relies on steam to assist slurry flow. The lateral shear force generated by the mixing components causes the slurry to rotate, and if the steam volume is too low, it cannot push the slurry through the gaps. However, the lateral shear force generated by the mixing components causes the slurry inside the mixing tank to rotate. If the steam volume is too low, the slurry cannot pass through the gaps; if the steam volume is too high, the temperature inside the slurry can easily rise, causing water evaporation and concentration fluctuations. Furthermore, high temperatures can make the mica flakes brittle, making them more prone to breakage during mixing, thus failing to effectively achieve the goals of squeezing, kneading, and dispersing. Summary of the Invention

[0005] This invention provides a composite stirring mica pulp preparation and processing device. Through the reciprocating compression of a piston block, the pulp is accelerated through a compression channel and forms a directional jet. This not only breaks up agglomerated mica flakes but also prevents excessive flake breakage through the flexible blades. This solves the problems mentioned in the background art, namely: the lateral shearing force generated by the stirring component causes the pulp inside the stirring tank to rotate; insufficient steam prevents the pulp from passing through gaps, while excessive steam easily leads to increased temperature, water evaporation, and concentration fluctuations within the pulp; furthermore, high temperatures can make the mica flakes brittle, making them more prone to breakage during stirring, thus failing to effectively achieve the purposes of compression, kneading, and dispersion.

[0006] To achieve the above objectives, a composite mixing mica pulp preparation and processing device includes a mixing tank. Multiple support legs are detachably connected to the bottom of the mixing tank. A discharge pipe is provided on one side of the bottom of the mixing tank. A viewing window is provided on the outer wall of the mixing tank. An opening is provided at the top of the mixing tank, and a sealing lid is detachably connected to the opening. A feed inlet is provided on the sealing lid, and a stirring assembly is installed on the sealing lid. The stirring assembly stirs the interior of the mixing tank. An extrusion spraying section is installed inside the mixing tank, and a reciprocating moving assembly is installed on the sealing lid. The reciprocating moving assembly drives the extrusion spraying section to move up and down reciprocally inside the mixing tank, extruding and spraying the pulp.

[0007] Based on this, a piston block is installed inside the mixing tank. Sealing rubber flanges are provided on the outer edges of the upper and lower sides of the piston block. An extrusion channel is provided in the center of the piston block. The two ends of the extrusion channel are provided with outward flares. A reciprocating moving component is installed on the sealed tank cover. The reciprocating moving component drives the piston block to move up and down reciprocally inside the mixing tank. When the piston block moves down or up, it extrudes the slurry in the direction of movement. After being extruded by the extrusion channel, the slurry increases its flow rate through the outward flares above, thus dispersing the agglomerated mica flakes.

[0008] In the above technical solution, when the piston block moves downward, it squeezes the slurry below. After being squeezed by the extrusion channel, the slurry increases its flow rate through the upper expansion port, replacing the high-speed stirring function in the traditional stirring process. This allows the agglomerated mica flakes to be dispersed without damaging the mica flakes.

[0009] Based on this, the stirring assembly includes a first servo motor, a stirring rod, and a first flexible stirring blade. The upper end of the sealed barrel cover is detachably connected to the first servo motor. The rotating end of the first servo motor passes through the sealed barrel cover, and the stirring rod is detachably connected to the rotating end of the first servo motor. Multiple first flexible stirring blades are provided on both the upper and lower sides of the stirring rod. The rotation of the first servo motor drives the stirring rod to rotate, and the stirring rod drives the multiple first flexible stirring blades on the upper and lower sides to rotate horizontally.

[0010] In the above technical solution, the first servo motor drives the stirring rod to rotate, and the stirring rod drives multiple first flexible stirring blades on the upper and lower sides to rotate horizontally, applying shear force to the mica flakes and additives inside, thereby achieving uniform mixing.

[0011] Based on this, mounting plates are detachably connected to the outer walls of the upper and lower sides of the stirring rod. The bottom of the lower mounting plate is provided with a second mounting groove that penetrates the side wall, and the top of the upper mounting plate is provided with a second mounting groove that penetrates the side wall. The end of each first flexible stirring blade is fixedly connected to a second rotating shaft. The second rotating shaft is rotatably connected to the inside of the second mounting groove. When the piston block moves up or down, it contacts the first flexible stirring blade, causing the first flexible stirring blade to rotate through the second rotating shaft, so that the first flexible stirring blade is housed inside the extrusion channel.

[0012] In the above technical solution, when the piston block moves up or down, it contacts the first flexible stirring blade, causing the first flexible stirring blade to rotate through the second rotating shaft, so that the first flexible stirring blade is housed inside the extrusion channel, thereby increasing the stroke of the piston block moving up and down.

[0013] Based on this, the reciprocating motion component includes a second servo motor, a drive screw, and a sliding rod. The second servo motor is detachably connected to one side of the upper end of the sealing barrel cover. The rotating end of the second servo motor passes through the sealing barrel cover and is detachably connected to the drive screw. The bottom of the drive screw is rotatably connected to the inner bottom of the mixing barrel. The piston block is threadedly connected to the drive screw. A sliding rod is detachably connected to the other side of the inside of the mixing barrel. The piston block is slidably connected to the outer wall of the sliding rod. The rotation of the second servo motor drives the drive screw to rotate, causing the piston block to move upward or downward inside the mixing barrel.

[0014] In the above technical solution, the rotation of the second servo motor drives the drive screw to rotate, thereby driving the piston block to move upward or downward inside the mixing tank, thus extruding the slurry.

[0015] Based on this, the piston block is detachably connected to both the upper and lower sides with lead screw bellows sleeves. The lead screw bellows sleeves on both sides are detachably connected to the inner bottom of the mixing tank and the bottom of the sealing tank cover, respectively. The lead screw bellows sleeves are fitted on the outside of the drive screw.

[0016] In the above technical solution, the corrugated sleeve of the lead screw can prevent the slurry from contacting the drive screw and causing it to rust, and can also prevent the mica scales from contacting the drive screw and causing it to break.

[0017] Based on this, four opposing first mounting slots are provided on the upper and lower sides of the piston block at the edge of the outer flare. The interior of each first mounting slot is rotatably connected to a first rotating shaft via a torsion spring. A sector plate is fixedly connected to the outer wall of each first rotating shaft. When the sector plates above and below the piston block are closed, they form a ring shape, and the edge of the sector plate fits with the outer flare. The central hole of the ring is the same as the inner diameter of the extrusion channel. When the piston block moves up and down, the sector plate in the direction of movement is closed by the torsion spring and the resistance of the slurry, while the sector plate on the other side is opened by the impact force of the slurry.

[0018] In the above technical solution, when the piston block moves up and down, the sector plate in the direction of piston block movement is closed by the torsion spring and the resistance of the slurry, while the sector plate on the other side is opened by the impact force of the slurry. The closed sector plate can effectively reduce residual slurry, while the open sector plate on the other side does not affect the acceleration of the slurry.

[0019] In another technical solution, an anti-settling component is provided at the bottom of the mixing tank. The anti-settling component is driven to rotate by the stirring component, and the anti-settling component stirs the slurry at the bottom of the mixing tank.

[0020] Based on this, the anti-sedimentation component includes a connecting plate, a second flexible stirring blade, an internal tooth groove, a first gear, and a second gear. The connecting plate is rotatably connected to the inner bottom of the mixing tank. Multiple second flexible stirring blades are provided on the outer wall of the connecting plate. The interior of the connecting plate is concave, and multiple internal tooth grooves are provided on the inner wall of the connecting plate. The stirring rod passes through the connecting plate and is located in the concave part of the connecting plate. The bottom of the stirring rod is detachably connected to the first gear. The first gear is rotatably connected to the inner bottom of the mixing tank. The second gear is rotatably connected to the inner bottom of the mixing tank. The second gear is located in the concave part of the connecting plate. The second gear meshes with the internal tooth groove and the first gear. A first servo motor drives the stirring rod to rotate. The stirring rod drives the first gear to rotate. The first gear drives the connecting plate and the second flexible stirring blade to rotate after being decelerated by the second gear.

[0021] In the above technical solution, when the first servo motor drives the stirring rod to rotate, the stirring rod drives the first gear to rotate. After the first gear is reduced in speed by the second gear, it drives the connecting plate and the second flexible stirring blade to rotate, thereby stirring the slurry at the bottom of the mixing tank and avoiding sedimentation of the slurry at the bottom which would affect the mixing effect.

[0022] In another technical solution, the extrusion jet section includes a piston block, with sealing rubber flanges provided on the outer edges of the upper and lower sides of the piston block, and multiple extrusion channels provided on the piston block, with outward flares provided at both ends of each extrusion channel.

[0023] In the above technical solution, when the piston block moves up and down through multiple extrusion channels, the slurry is extruded and sprayed outward through the outer flare. During the spraying, the slurry sprayed from adjacent extrusion channels will collide with each other.

[0024] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0025] 1. In this composite stirring mica pulp preparation and processing device, the pulp is accelerated through the extrusion channel by the reciprocating squeezing of the piston block to form a directional jet, which can not only break up the agglomerated mica flakes, but also avoid excessive flake breakage through the characteristics of the flexible blades. The connecting plate at the bottom of the mixing tank and the second flexible stirring blade rotate synchronously through gear transmission to prevent the pulp from settling at the bottom.

[0026] 2. In this composite stirring mica pulp preparation and processing device, the sector plate on the piston block achieves adaptive opening and closing through a torsion spring, which reduces pulp residue in the channel. Combined with the sealing effect of the sealing rubber flange, it prevents pulp leakage and thus avoids wear of the piston block. Attached Figure Description

[0044] The technical solutions of this invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this invention, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0045] Because the mixing components generate lateral shear force, the slurry inside the mixing tank rotates. If the steam is too little, the slurry cannot pass through the gaps. If the steam is too much, the temperature inside the slurry will rise, causing water to evaporate and concentration to fluctuate. Furthermore, high temperature can make the mica flakes brittle, making them more prone to breakage during mixing, thus failing to effectively achieve the purpose of squeezing, kneading, and dispersing.

[0046] Therefore, in view of the above-mentioned problems, the present invention provides a composite stirring mica pulp preparation and processing device.

[0047] Example 1: As Figure 1-2As shown, this is a preferred embodiment of the present invention. The composite stirring mica pulp preparation and processing device in this embodiment includes a mixing tank 100. The bottom of the mixing tank 100 is detachably connected to multiple support legs 101. A discharge pipe 102 is provided on one side of the bottom of the mixing tank 100. A viewing window 103 is provided on the outer wall of the mixing tank 100. An opening is provided on the top of the mixing tank 100. A sealing tank cover 104 is detachably connected to the opening. A feed inlet 105 is provided on the sealing tank cover 104. In this embodiment, mica flakes and other additives are added to the interior of the mixing tank 100 through the feed inlet 105 for thorough mixing. After mixing, the mixed pulp can be discharged outward through the discharge pipe 102. The design of the viewing window 103 allows observation of the mixing of the pulp inside during the mixing process.

[0048] Mica sheets and other additives need to be mixed evenly by stirring. A specific stirring structure can be used as follows: Figure 3-5 In the embodiment shown, a first servo motor 300 is detachably connected to the upper end of the sealed barrel cover 104. The rotating end of the first servo motor 300 passes through the sealed barrel cover 104. A stirring rod 301 is detachably connected to the rotating end of the first servo motor 300. Multiple first flexible stirring blades 302 are provided on both the upper and lower sides of the stirring rod 301. In this embodiment, the first servo motor 300 rotates to drive the stirring rod 301 to rotate. The stirring rod 301 drives the multiple first flexible stirring blades 302 on the upper and lower sides to rotate horizontally, applying shear force to the mica flakes and additives inside, thereby achieving uniform mixing.

[0049] Simply using horizontal stirring of the mixing assembly will prevent the clumped mica flakes from dispersing, thus hindering uniform mixing. To solve this problem, a specific structure can be adopted as follows: Figure 3 as well as Figure 4 In the embodiment shown, a piston block 200 is provided inside the mixing tank 100. A compression channel 201 is provided at the center of the piston block 200, and flared openings 202 are provided at both ends of the compression channel 201. A reciprocating moving assembly 500 is installed on the sealing tank cover 104. The reciprocating moving assembly 500 drives the piston block 200 to move up and down reciprocally inside the mixing tank 100. In this embodiment, when the piston block 200 moves downwards, it compresses the slurry below. After being compressed by the compression channel 201, the slurry increases its flow rate through the flared openings 202 above, replacing the high-speed stirring function in the traditional stirring process. This allows for the dispersion of agglomerated mica flakes without damaging them. When the mica flakes move upwards and contact the first flexible stirring blade 302, the flexible characteristics of the first flexible stirring blade 302 prevent damage to the mica flakes. The specific flow direction of the slurry is as follows... Figure 4As shown, when the piston block 200 moves upward, the same principle applies. When the mixing is completed and the material is discharged outward, the piston block 200 moves up and down repeatedly, which can push the slurry outward and increase the discharge speed.

[0050] Because the first flexible stirring blades 302 on both sides are located in the upper and lower middle parts inside the mixing tank 100, sedimentation easily occurs at the bottom inner side of the mixing tank 100. To avoid sedimentation at the bottom of the mixing tank 100, the specific structure can be as follows: Figure 5 In the embodiment shown, a connecting plate 400 is rotatably connected to the inner bottom of the mixing tank 100. Multiple second flexible stirring blades 403 are provided on the outer wall of the connecting plate 400. The connecting plate 400 is concave, and its inner wall is provided with multiple internal toothed grooves 401. A stirring rod 301 passes through the connecting plate 400 and is located in the concave part of the connecting plate 400. A first gear 304 is detachably connected to the bottom of the stirring rod 301. The first gear 304 is rotatably connected to the inner bottom of the mixing tank 100. A second gear 402 is rotatably connected to the inner bottom of the mixing tank 100. 2 is located in the recess of the connecting plate 400. The second gear 402 meshes with the inner tooth groove 401 and the first gear 304. In this embodiment, when the first servo motor 300 drives the stirring rod 301 to rotate, the stirring rod 301 drives the first gear 304 to rotate. After the first gear 304 is decelerated by the second gear 402, it drives the connecting plate 400 and the second flexible stirring blade 403 to rotate, thereby stirring the slurry at the bottom of the mixing tank 100, avoiding the sedimentation of the bottom slurry from affecting the mixing effect. Furthermore, during discharge, the stirring of the second flexible stirring blade 403 can assist in the discharge.

[0051] When the piston block 200 moves up and down, it is restricted by the position of the first flexible stirring blades 302 on both sides, which shortens the movement distance of the piston block 200 and makes it impossible to fully compress the slurry. In order to increase the stroke of the piston block 200 and ensure that all the slurry is compressed, the specific structure can be as follows: Figure 5 as well as Figure 6In this embodiment, the outer walls of the upper and lower sides of the stirring rod 301 are detachably connected to mounting plates 303. The bottom of the lower mounting plate 303 is provided with a second mounting groove 306 that penetrates the side wall, and the top of the upper mounting plate 303 is provided with a second mounting groove 306 that penetrates the side wall. The end of each first flexible stirring blade 302 is fixedly connected to a second rotating shaft 305. The second rotating shaft 305 is rotatably connected to the inside of the second mounting groove 306. In this embodiment, when the piston block 200 moves up or down, it contacts the first flexible stirring blade 302, causing the first flexible stirring blade 302 to rotate through the second rotating shaft 305. This allows the first flexible stirring blade 302 to be housed inside the extrusion channel 201, thereby increasing the stroke of the piston block 200 moving up and down, resulting in a better extrusion effect on the slurry. Furthermore, when the first flexible stirring blade 302 is inside the extrusion channel 201, it can continue to rotate, stirring the slurry passing through the extrusion channel 201, and making the sprayed slurry form a more stable jet.

[0052] The reciprocating motion assembly 500 includes a second servo motor 501, a drive screw 502, and a sliding rod 503. The second servo motor 501 is detachably connected to one side of the upper end of the sealing barrel cover 104. The rotating end of the second servo motor 501 passes through the sealing barrel cover 104 and is detachably connected to the drive screw 502. The bottom of the drive screw 502 is rotatably connected to the inner bottom of the mixing barrel 100. The piston block 200 is threadedly connected to the drive screw 502. The sliding rod 503 is detachably connected to the other side of the inside of the mixing barrel 100. The piston block 200 is slidably connected to the outer wall of the sliding rod 503. The upper and lower sides of the piston block 200 are detachably connected to lead screw corrugated sleeves 504. 4 is detachably connected to the inner bottom of the mixing tank 100 and the bottom of the sealing tank cover 104 respectively. The lead screw corrugated sleeve 504 is sleeved on the outside of the drive screw 502. In this embodiment, the second servo motor 501 rotates to drive the drive screw 502 to rotate, thereby driving the piston block 200 to move upward or downward inside the mixing tank 100 to squeeze the slurry. The lead screw corrugated sleeve 504 can prevent the slurry from contacting the drive screw 502 and causing the drive screw 502 to rust, and can also prevent the mica scales from contacting the drive screw 502 and causing damage. The lead screw corrugated sleeve 504 automatically extends or shortens during the upward or downward movement of the piston block 200.

[0053] Because of the design of the flared opening 202, some slurry cannot pass through the extrusion channel 201 when the piston block 200 moves up and down. To solve this problem, a specific structure can be adopted as follows: Figure 7 as well as Figure 8In this embodiment, four opposing first mounting grooves 205 are provided on the upper and lower sides of the piston block 200 at the edge of the flared opening 202. A first rotating shaft 203 is rotatably connected inside each first mounting groove 205 via a torsion spring. A sector plate 204 is fixedly connected to the outer wall of each first rotating shaft 203. When the sector plates 204 above and below the piston block 200 are closed, they form an annular shape, and the edge of the sector plate 204 fits against the flared opening 202. The central hole of the annular shape has the same inner diameter as the extrusion channel 201. Sealing rubber flanges 206 are provided at the outer edges of the upper and lower sides. In this embodiment, when the piston block 200 moves up and down, the sector plate 204 in the direction of movement of the piston block 200 is closed by the resistance of the torsion spring and the slurry, while the sector plate 204 on the other side is opened by the impact force of the slurry. The closed sector plate 204 can effectively reduce the residual slurry, while the open sector plate 204 on the other side does not affect the acceleration of the slurry. The sealing rubber flanges 206 can prevent the slurry from entering between the piston block 200 and the mixing tank 100.

[0054] If the mica flakes added to the mixing tank 100 are too large, they can easily clog the extrusion channel 201, preventing proper mixing. To avoid this problem, a specific structure can be adopted as follows: Figure 9 In the embodiment shown, a filter screen plate 106 is inserted into the side wall of the feed inlet 105, and side baffles 107 are fixedly connected to both sides of the filter screen plate 106. A first handle 108 is fixedly connected to the side of the filter screen plate 106 near the outside. A sealing plate 109 is inserted into the outer wall of the feed inlet 105 below the filter screen plate 106, and a second handle 110 is fixedly connected to the outer wall of the sealing plate 109. In this embodiment, when adding raw materials, pulling the second handle 110 outward allows the raw materials to pass through the filter screen plate 106 and enter the interior of the mixing tank 100, thereby preventing large mica flakes from entering and clogging the extrusion channel 201. After the material is added, pushing the second handle 110 inward causes the sealing plate 109 to seal the feed inlet 105, thereby preventing the slurry from leaking out of the feed inlet 105 when the piston block 200 moves up and down, causing environmental pollution and waste.

[0055] Example 2: Figure 10 As shown, this is another preferred embodiment of the present invention. The difference between this embodiment and embodiment 1 is that there are multiple extrusion channels 201 on the piston block 200. Each extrusion channel 201 has an outer flare 202 at both ends. The stirring rod 301 passes through the extrusion channel 201 at the center. In this embodiment, when the piston block 200 moves up and down through the multiple extrusion channels 201, the slurry is extruded and sprayed outward through the outer flare 202. During spraying, the slurry sprayed from adjacent extrusion channels 201 will collide with each other, which helps to disperse the clumps of mica flakes and improves the mixing effect of the slurry.

[0056] Example 3: As Figure 11 As shown, this is another preferred embodiment of the present invention. The difference between this embodiment and embodiment 2 is that the bottom of the piston block 200 is provided with a bottom flare 207, and multiple extrusion channels 201 are connected to the bottom flare 207. In this embodiment, by setting the bottom flare 207, the slurry above can flow back faster during the upward movement of the piston block 200. Therefore, the upward movement path of the piston block 200 is reduced, and the piston block 200 can achieve the effects of spraying, dispersing and mixing by moving a shorter distance.

[0057] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments.
