Description

Technical Field

[0001] The present invention relates to the technical field of reaction kettles, and particularly to a reaction kettle and method for producing water-based tobacco glue. Background Art

[0002] Water-based tobacco glue is a special adhesive used in the tobacco industry. It is a type of adhesive with water as the solvent or dispersion medium, mainly including water-based resins, thickeners, humectants, and other additives. Using water as the solvent or dispersion medium, almost no organic solvents are released during use, greatly reducing the emission of volatile organic compounds and being relatively friendly to the environment and human health. Common water-based resins include vinyl acetate copolymers and acrylates, and vinyl acetate copolymers and acrylates have certain corrosiveness.

[0003] Reaction kettles are often used in the production of water-based tobacco glue. Water-based resins, thickeners, humectants, and other additives are placed in the reaction kettle, and the stirrer rotates driven by a motor, generating liquid flows in different directions, so that various raw materials such as water-based resins, thickeners, humectants, and additives in the kettle are forced to convect and mix under the action of centrifugal force, axial force, etc., promoting the uniform dispersion among components.

[0004] In the patent document with the publication number CN115430381B, a reaction kettle is proposed. Among them, the output shaft of the motor drives the first stirring component to rotate through a rotating disk, and the stirring rod stirs the materials in the shell. Since the number of stirring rods is large, the range involved in stirring is large, and the materials can be stirred evenly more quickly, thus saving electric energy; during the stirring process of the stirring rod, it will deflect slightly due to hitting solid materials, and the setting of the compression spring can increase the deflection amplitude of the stirring rod, so that the stirring rod can stir the materials radially relative to the rotating disk, which is beneficial to improving the stirring effect of the materials. The stirring rod drives the installation disk to rotate through a wire, so that the stirring part on the installation disk can rotate synchronously, thereby stirring the materials near the vertical center line of the shell, which is beneficial to improving the comprehensiveness of stirring the materials in the shell.

[0005] However, during the stirring process of the above reaction kettle, the water-based glue raw materials are easily adhered to the inner wall of the reaction kettle and the stirrer, forming a relatively thick material layer, which will not only cause this part of the materials not to fully participate in the mixing, but may also affect the heat transfer and stirring effect, and even require frequent shutdowns for cleaning. Summary of the Invention

[0006] The object of the present invention is to address the problem that the water-based glue raw materials adhere to the inner wall of the reaction kettle to form a material layer in the background art, and propose a reaction kettle and method for producing water-based tobacco glue.

[0018] On the other hand, the present invention provides a method for producing water-based glue for cigarettes, which is applied to the above-mentioned reaction kettle for producing water-based glue for cigarettes, and the steps are as follows:

[0019] S1. By placing an aqueous resin, a thickening agent, a moisturizing agent, and other additives into the reaction tank, sealing the reaction tank through the closing cover, heating the water-based glue raw materials inside the reaction tank, and stirring the water-based glue raw materials by the stirring blade;

[0020] S2. Since the production of water-based glue requires heat absorption, and the solvent of the water-based glue raw materials is water, the water absorbs heat to form water vapor, and the water vapor exerts pressure on the pressure relief piston and makes it move, so as to transfer the water vapor into the heat preservation tank;

[0021] S3. Send the water vapor in the heat preservation tank into the bifurcated pipe through an air pump, and increase the flow rate of the water vapor. The water vapor is ejected from the steam injection ports at the bottom of the steam injection ring and sprayed on the inner wall of the reaction tank. Since there is a distance between the stirring blade and the inner wall of the reaction tank, there is an unmixed material layer on the inner wall of the reaction tank. Separate the material layer on the inner wall of the reaction tank through the steam.

[0022] S4. Rotate the stirring blade to drive the blocking plate to rotate, so that the position of the blocking plate under the steam injection ring is continuously changed, allowing the steam injection ports at different positions to leak out. By blocking the redundant steam injection ports, the ejection speed of the steam is increased to better separate the material layer.

[0023] S5. Rotate the extrusion arc plate to extrude the ball head, so that one of the first connecting block and the second connecting block is in an open state. Use the intermediate separation block to separate the inside of the steam injection ring, shorten the moving distance of the water vapor in the steam injection ring, avoid heat loss of the water vapor, and prevent the heat and binding force from being unable to cooperate to separate the material layer.

[0024] Compared with the prior art, the present invention has the following beneficial technical effects:

[0025] 1. When water-based glue is produced in the reaction tank to form water vapor and increase the pressure in the reaction tank, pressure relief is carried out through the pressure relief piston and the pressure relief port, and the water vapor is introduced into the steam injection ring by the air pump and ejected from the steam injection port. The heat of the water vapor is used to heat and impact the material layer, and the shear force applied to the material layer by the rotation of the stirring blade is combined to separate the material layer, avoiding the situation that raw materials do not participate in the production of water-based glue and preventing the material layer from affecting heat transfer and stirring during the production of water-based glue.

[0026] 2. The steam injection port is blocked by the blocking plate. On the one hand, the number of open steam injection ports is reduced to increase the injection pressure and flow rate of the water vapor ejected from the open steam injection ports, so as to improve the separation effect of the material layer. At the same time, the diameter of the gear is larger than the diameter of the rotating shaft of the stirring blade to reduce the rotation speed of the blocking plate and extend the action time of the water vapor on the material layer, further improving the separation effect of the material layer.

[0027] 3. When the position of the blocking plate is changed, the ball head is extruded by the extrusion arc plate, thereby blocking the one-to-two pipe, so that the water vapor enters the steam injection ring in the one-to-two pipe closest to the open steam injection port, avoiding heat loss of the water vapor and preventing the heat and binding force from being unable to cooperate.

[0044] Embodiment

[0045] This embodiment provides a reactor for the production of water-based cigarette glue, as Figure 1 and Figure 2 shown, which includes a reaction tank 1. A closed cover 2 is fixedly installed at the top of the reaction tank 1. A stirring blade 4 is rotatably connected to the center of the bottom of the closed cover 2. By placing aqueous resin, thickener, moisturizer and other additives into the interior of the reaction tank 1, the reaction tank 1 is sealed by the closed cover 2. The reaction tank 1 heats the water-based glue raw materials inside, and the stirring blade 4 stirs the water-based glue raw materials.

[0046] As Figure 3 shown, a motor 3 is fixedly installed at the top of the closed cover 2. The bottom of the motor 3 is fixedly connected to the stirring blade 4 through a rotating shaft. A plurality of pull rings 8 are fixedly installed at the top of the stirring blade 4. The interior of the reaction tank 1 is provided with water-based glue raw materials. Since there is a gap between the stirring blade 4 and the reaction tank 1, and the water-based glue is viscous, a material layer will be formed on the inner wall of the reaction tank 1, and the material layer cannot be mixed by the stirring blade 4.

[0047] As Figures 4 to 7As shown, a material layer separation component 5 is provided at the bottom of the closing cover 2, and the material layer separation component 5 includes a pressure relief component, a heat preservation tank 55, an air pump 56, a two-pipe 57, a steam injection ring 58 and a steam injection port 59. The pressure relief component includes a cylinder 51, a pressure relief piston 52, a spring telescopic rod 53 and a pressure relief port 510. The cylinder 51 is fixedly mounted on the inner wall of the closing cover 2, and the pressure relief piston 52 slides up and down on the inner wall of the cylinder 51. The top of the pressure relief piston 52 is elastically connected to the cylinder 51 through the spring telescopic rod 53, and the side of the cylinder 51 is provided with a pressure relief port 510, and the pressure relief piston 52 blocks the pressure relief port 510.

[0048] Since the production of water-based adhesive requires the absorption of heat, and the solvent of the water-based adhesive raw material is water, water absorbs heat to form water vapor, and the water vapor exerts pressure on the pressure relief piston 52 and causes it to move. The pressure relief piston 52 moves upward to compress the spring telescopic rod 53, and the pressure relief piston 52 no longer blocks the pressure relief port 510. At this time, the water vapor enters the insulation tank 55.

[0049] A hose 54 is fixedly installed between the insulation tank 55 and the pressure relief port 510 , and a one-way valve 511 is fixedly installed between the end of the hose 54 and the insulation tank 55 . The one-way valve 511 prevents the water vapor in the insulation tank 55 from flowing back into the interior of the reaction tank 1 .

[0050] like Figure 6 As shown, an air pump 56 is fixedly installed at the bottom of the insulation tank 55, a two-piece pipe 57 is fixedly installed at the bottom of the air pump 56, a steam injection ring 58 is fixedly installed at the end of the two-piece pipe 57, a plurality of steam injection ports 59 are provided at the bottom of the steam injection ring 58, and the plurality of steam injection ports 59 are distributed at equal angles in a ring shape at the bottom of the steam injection ring 58, the steam injection ring 58 is fixedly installed at the bottom of the closing cover 2 and close to the edge of the reaction tank 1, and the injection ports of the steam injection ports 59 are inclined and face the inner wall of the reaction tank 1.

[0051] The water vapor in the heat preservation tank 55 is extracted by the air pump 56 and enters the one-way pipe 57. The water vapor then enters the steam injection ring 58 from the one-way pipe 57 and is finally ejected from the steam injection port 59. The water vapor impacts the material layer on the inner wall of the reaction tank 1. The steam has high temperature and high humidity. When the high-temperature and high-humidity steam is introduced into the environment where the adsorbent with the adsorbent attached is located, the steam will release a large amount of heat. The heat can provide enough energy to destroy the binding force between the adsorbent and the solid surface, including the van der Waals force in physical adsorption and the chemical bond force in possible chemical adsorption, so that the adsorbent falls off the adsorbent surface.

[0052] At the same time, the rotation of the stirring blade 4 applies a shear force to the material layer. The stirring blade 4 is used together with water vapor to improve the separation effect of the material layer. The water vapor impacts the material layer, and the heat eventually returns to the reaction tank 1, preventing the water vapor from taking away the heat inside the reaction tank 1 and affecting the production of water-based adhesive.

[0053] The steam ejected from the steam injection ports 59 is fan-shaped, and the steam ejected from two adjacent steam injection ports 59 intersects with each other, preventing the existence of a material layer not covered by water vapor. Compared with the method of scraping off the material layer, since the inner wall of the reaction tank 1 has a coating and the water-based glue raw material is corrosive, scraping the material layer will damage the coating inside the reaction tank 1, and the reaction tank 1 will be corroded by the water-based glue raw material.

[0054] In the present invention, the water-based glue produced in the reaction tank 1 forms water vapor and increases the pressure in the reaction tank 1. The pressure is relieved through the pressure relief piston 52 and the pressure relief port 510, and the water vapor is introduced into the steam injection ring 58 by the air pump 56 and ejected from the steam injection ports 59. The heat of the water vapor is used to heat and impact the material layer, and the shear force applied to the material layer by the rotation of the stirring blade 4 is combined to detach the material layer, preventing the existence of raw materials that do not participate in the production of the water-based glue and preventing the material layer from affecting heat transfer and stirring during the production of the water-based glue.

[0055] As Figure 5 and Figure 7 shown, a diversion component 6 for adjusting the steam injection position is provided at the bottom of the steam injection port 59. The diversion component 6 includes a transmission member, a rotating ring 63, a blocking plate 65 and a rubber layer 66. A transmission member is provided at the bottom of the closing cover 2, and the stirring blade 4 is connected to the rotating ring 63 through the transmission member. The outer arc surface of the rotating ring 63 is fixedly provided with a blocking plate 65, the top of the blocking plate 65 is slidably connected to the steam injection ring 58, and the top of the blocking plate 65 is fixedly provided with a rubber layer 66.

[0056] A notch is provided on the blocking plate 65, and the notch occupies one-third to one-half of the blocking plate 65. The steam injection ports 59 at the bottom of the steam injection ring 58 leak out from the notch, and the rubber layer 66 blocks the steam injection ports 59. By rotating the stirring blade 4 and driving the rotating ring 63 to rotate by using the transmission component, the blocking plate 65 changes its position, so that some of the steam injection ports 59 are in a closed state. Closing some of the steam injection ports 59 increases the injection pressure of the water vapor at the unclosed steam injection ports 59. The blocking plate 65 continuously changes its position below the steam injection ring 58, so that the steam injection ports 59 at different positions eject water vapor.

[0057] The transmission member includes a chain 61, a gear 62 and teeth 64. The top of the gear 62 is rotatably connected to the closing cover 2. The gear 62 is connected to the stirring blade 4 through the chain 61. A plurality of annular teeth 64 distributed at equal angles are fixedly installed on the inner arc surface of the rotating ring 63. The gear 62 is meshed with the teeth 64, and the diameter of the gear 62 is larger than the diameter of the rotating shaft of the stirring blade 4.

[0058] Moreover, since the diameter of the gear 62 is larger than the diameter of the rotating shaft of the stirring blade 4, the stirring blade 4 needs to rotate several circles before the gear 62 can rotate one circle. As a result, the blocking plate 65 rotates slowly, allowing the steam injection ports 59 not blocked by the blocking plate 65 to continuously eject water vapor, thereby prolonging the action time of the water vapor on the material layer.

[0059] In the present invention, by blocking the steam injection ports 59 with the blocking plate 65, on the one hand, the number of open steam injection ports 59 is reduced to increase the injection pressure and flow rate of the water vapor ejected from the open steam injection ports 59, so as to improve the separation effect of the material layer. At the same time, taking advantage of the fact that the diameter of the gear 62 is larger than the diameter of the rotating shaft of the stirring blade 4, the rotation speed of the blocking plate 65 is reduced to prolong the action time of the water vapor on the material layer, further improving the separation effect of the material layer.

[0060] As Figure 8 and Figure 9 shown, a distance-reducing assembly 7 is provided at the top of the steam injection ring 58. The distance-reducing assembly 7 includes a pressing arc plate 71, an inclined surface 72, a first connecting block 73, a second connecting block 74, a ball head 76 and a closing member. The pressing arc plate 71 is fixedly installed at the top of the blocking plate 65. Both ends of the pressing arc plate 71 are provided with inclined surfaces 72. The first connecting block 73 and the second connecting block 74 are fixedly installed between the top of the steam injection ring 58 and the bifurcated pipe 57. Closing members are provided inside both the first connecting block 73 and the second connecting block 74, and ball heads 76 are provided at the ends of the closing members. The outer arc surface of the pressing arc plate 71 contacts the ball heads 76.

[0061] By rotating the pressing arc plate 71 and pressing the ball heads 76, one of the first connecting block 73 and the second connecting block 74 is in an open state. The inside of the steam injection ring 58 is separated by the intermediate separation block 75, shortening the moving distance of the water vapor in the steam injection ring 58 and preventing the heat dissipation of the water vapor, so that the heat and the binding force cannot cooperate to separate the material layer.

[0062] As Figure 10 shown, the closing member includes a straight rod 77, a closing plug 78 and a return spring 79. The straight rod 77 is fixedly installed at the end of the ball head 76. The straight rod 77 penetrates into the inside of the second connecting block 74. The closing plug 78 is fixedly installed at the end of the straight rod 77. The closing plug 78 blocks the bifurcated pipe 57. The ball head 76 is elastically connected to the second connecting block 74 by the return spring 79. Two symmetrically arranged intermediate separation blocks 75 are fixedly installed inside the steam injection ring 58. The first connecting block 73 and the second connecting block 74 are symmetrically arranged at the top of the steam injection ring 58. The first connecting block 73, the second connecting block 74 and the two intermediate separation blocks 75 form a cross-shaped connection.

[0063] By squeezing the ball head 76 with the squeezing arc plate 71, the closing plug 78 completely blocks the one-to-two pipe 57, thereby closing the first connection block 73 or the second connection block 74. One of the first connection block 73 and the second connection block 74 is in an open state. When the first connection block 73 is close to the unobstructed steam injection port 59, the first connection block 73 opens and the second connection block 74 closes. When the second connection block 74 is close to the unobstructed steam injection port 59, the first connection block 73 closes and the second connection block 74 opens. The steam injection ring 58 is divided into two parts by cooperating with the intermediate separation block 75, so that the one-to-two pipe 57 closest to the open steam injection port 59 is in an open state, and the water vapor enters the steam injection ring 58 in the one-to-two pipe 57 closest to the open steam injection port 59, avoiding heat dissipation.

[0064] When the blocking plate 65 of the present invention changes its position, the ball head 76 is squeezed by the squeezing arc plate 71, thereby blocking the one-to-two pipe 57, so that the water vapor enters the steam injection ring 58 in the one-to-two pipe 57 closest to the open steam injection port 59, avoiding the loss of water vapor heat and being unable to cooperate with heat and binding force.

[0065] A production method of water-based glue for cigarettes, which is applied to the above-mentioned reaction kettle for producing water-based glue for cigarettes, and the steps are as follows:

[0066] S1. By placing the aqueous resin, thickener, moisturizer and other additives into the interior of the reaction tank 1, the reaction tank 1 is sealed by the sealing cover 2, the reaction tank 1 heats the water-based glue raw materials inside, and the stirring blade 4 stirs the water-based glue raw materials;

[0067] S2. Since the production of water-based glue requires heat absorption, and the solvent of the water-based glue raw materials is water, the water absorbs heat to form water vapor, and the water vapor exerts pressure on the pressure relief piston 52 and makes it move, thereby transferring the water vapor to the heat preservation tank 55;

[0068] S3. The water vapor in the heat preservation tank 55 is sent into the one-to-two pipe 57 by the air pump 56, and the flow rate of the water vapor is increased. The water vapor is ejected from the steam injection port 59 at the bottom of the steam injection ring 58 and sprayed on the inner wall of the reaction tank 1. Since there is a gap between the stirring blade 4 and the inner wall of the reaction tank 1, there is an unmixed material layer on the inner wall of the reaction tank 1, and the material layer on the inner wall of the reaction tank 1 is separated by the steam;

[0069] S4. The stirring blade 4 rotates to drive the blocking plate 65 to rotate, so that the blocking plate 65 continuously changes its position below the steam injection ring 58, so that the steam injection ports 59 at different positions are exposed. By blocking the redundant steam injection ports 59, the ejection speed of the steam is increased, and the material layer separation is better carried out;

[0070] S5. Rotate and squeeze the ball head 76 through the extrusion arc plate 71, so that one of the first connecting block 73 and the second connecting block 74 is in an open state, and use the middle separation block 75 to separate the inside of the steam injection ring 58, shortening the moving distance of water vapor in the steam injection ring 58, avoiding heat loss of water vapor, and being unable to utilize heat and bonding force to cooperate to separate the material layer.

[0071] The above specific embodiments are only several alternative embodiments of the present invention. Based on the technical solution of the present invention and the relevant revelations of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.

10. A method for producing water-based adhesive for cigarettes, applied to the reaction kettle for producing water-based adhesive for cigarettes as claimed in claim 9, comprising the following steps: S1, placing a water-based resin, a thickener, a moisturizer and other additives into a reaction tank (1), sealing the reaction tank (1) with a sealing cover (2), heating the water-based adhesive raw material inside the reaction tank (1), and stirring the water-based adhesive raw material with a stirring blade (4); S2. Since the production of water-based adhesive requires the absorption of heat, and the solvent of the water-based adhesive raw material is water, the water absorbs heat to form water vapor, and the water vapor exerts pressure on the pressure relief piston (52) and causes it to move, thereby transferring the water vapor to the insulation tank (55); S3, the water vapor in the heat preservation tank (55) is sent into the one-dividing-two pipe (57) by the air pump (56), and the flow rate of the water vapor is increased, and the water vapor is sprayed out from the steam injection port (59) at the bottom of the steam injection ring (58) and sprayed onto the inner wall of the reaction tank (1). Since there is a gap between the stirring blade (4) and the inner wall of the reaction tank (1), there is an unmixed material layer on the inner wall of the reaction tank (1), and the material layer on the inner wall of the reaction tank (1) is separated by the steam; S4, the stirring blade (4) rotates and drives the obstruction plate (65) to rotate, so that the obstruction plate (65) is constantly switched to a position below the steam injection ring (58), so that steam injection ports (59) at different positions leak out, and the steam injection speed is increased by blocking the redundant steam injection ports (59), so as to better separate the material layers; S5. The extrusion arc plate (71) is rotated and the ball head (76) is squeezed so that one of the first connecting block (73) and the second connecting block (74) is in an open state, and the interior of the steam injection ring (58) is separated by the intermediate separation block (75), thereby shortening the distance that the water vapor moves in the steam injection ring (58) and preventing the heat of the water vapor from being lost, thereby preventing the material layers from being separated by using the heat and the bonding force.
