Description

Technical Field

[0001] The invention belongs to the field of plastic additive production, in particular to a reaction kettle for plastic additive production. Background Art

[0002] Plastic additives, also known as plastic additives, are some compounds that must be added during the molding process of polymers to improve their processing properties or to improve the insufficient performance of the resin itself. They occupy a particularly important position in plastic molding and can significantly improve the performance and quality of plastic products. In the production process of plastic additives, multiple chemical raw materials need to be put into the reactor for stirring and reaction to finally obtain the finished product.

[0003] The patent with announcement number CN218307385U discloses a special engineering plastic additive production reactor, which relates to the technical field of reactors, including a reactor body, a feeding pipe fixedly connected to the upper surface of the reactor body, and a feeding pipe fixedly connected to the bottom surface of the reactor body. The utility model has a reasonable design structure. It is equipped with a rotating table, a first motor, a second motor, a bidirectional screw, a mixing mechanism and a dispersion plate. The first motor can drive the rotating table to rotate on the reactor body, and the dispersion plate can disperse the raw materials entering the reactor body through the feeding pipe, so that the raw materials can be dispersed and put into the interior of the reactor body to avoid the accumulation of raw materials inside the reactor body. The second motor drives the bidirectional screw to rotate, which can enable the push plate to push the materials in the reactor body inward and outward, effectively improving the fluidity of the raw materials in the reactor body, thereby reducing the time spent on mixing the raw materials evenly.

[0004] However, the above technical solution still has the following deficiencies in practical application: During the production and processing of raw materials, some solid raw materials with larger particles and not completely crushed may be included. If these large particles are directly fed into the kettle for reaction, it may affect the uniformity of the reaction. In addition, during the production process, some solid impurities may be mixed into the raw materials, such as metal fragments, stones, etc. These solid impurities, when mixed with the raw materials, will affect the purity of the final product.

At this time, the L-shaped rod is driven down to enter the fence, and then the pushing rod is driven to move to carry out the dredging work, which can avoid the push rod squeezing the large pieces of raw materials or impurities into the through hole, causing the ejection barrel and the through hole to deform and affect the ejection effect. In addition, it also avoids the large pieces of raw materials being squeezed and crushed and scattered into the ejection barrel, which makes it more troublesome to collect the large pieces of raw materials again. There is no need to clean the inside of the ejection barrel before each dredging work. After multiple dredging works, the large pieces of raw materials and impurities can be collected and processed uniformly. BRIEF DESCRIPTION OF THE DRAWINGS

The piston end of the electric push rod 38 is fixedly connected to a scraper 36. The upper end surface of the scraper 36 is fixedly connected to the front and rear sides of the upper end surface of the scraper 36. The slide rod 37 is slidably connected to the upper end of the kettle body 1; A gear ring 20 is sleeved and fixedly connected on the upper side of the ejection tube 10, a fixed block 23 is fixedly connected to the middle part of the front side of the upper end face of the kettle body 1, a motor 3 22 is fixedly connected to the left side of the upper end face of the fixed block 23, a gear 21 is fixedly connected to the output end of the motor 3 22, the gear 21 is rotatably arranged on the fixed block 23, and the gear 21 is meshed with the outer gear block of the gear ring 20; Specifically, plastic additives, also known as plastic additives, are some compounds that must be added when polymers are molded to improve their processing properties or to improve the insufficient properties of the resin itself. They play a particularly important role in plastic molding and can significantly improve the performance and quality of plastic products. In the production process of plastic additives, each chemical raw material needs to be added in a proportion and in the order required by the process, and then put into a reactor for stirring and reaction to finally obtain a finished product; when using an existing reactor for the production of plastic additives, the raw materials are added into the reactor body 1 and mixed by stirring. However, since the raw materials may contain some solid raw materials with larger particles and not completely crushed during the production and processing, if these large particles of raw materials are directly put into the reactor body 1 for reaction, it may affect the uniformity of the reaction, and some solid impurities, such as metal fragments, stones, etc., may be mixed into the raw materials during the production process. After these solid impurities are mixed with the raw materials, they will affect the purity of the final product; Therefore, when the present embodiment is in use, the raw materials are added into the inside of the throwing-out cylinder 10, and then the cylinder cover 19 is driven to rotate by the motor 24 to close the upper end of the throwing-out cylinder 10, and then the motor 3 22 is started to drive the gear 21 to rotate, so that the gear ring 20 and the throwing-out cylinder 10 can be continuously rotated. Under the action of centrifugal force, small pieces of raw materials can be thrown out into the inside of the kettle body 1 through the through hole 45, while large pieces of raw materials and impurities will be blocked by the through hole 45. The blocked large pieces of raw materials can be collected and re-crushed in the future, and then added to the kettle body 1 again. By throwing the raw materials into the inside of the kettle body 1, the raw materials can be evenly distributed in the inside of the kettle body 1, avoiding the situation that the raw materials are in the same position every time they enter the kettle body 1, thereby affecting the mixing effect of the raw materials, and also avoiding the situation that large pieces of raw materials and impurities enter the kettle body 1 together and mix with the raw materials, affecting the purity of the final product. During the raw material throwing process, the raw material may adhere to the inner wall of the through hole 45 and block the through hole 45, which not only affects the amount of raw material added, but also affects the subsequent throwing of the raw material. Therefore, when the through hole 45 has raw materials attached to the wall, the barrel cover 19 can be driven to open. If there are no large pieces of raw materials and impurities in the throwing barrel 10 at this time, the motor 639 can be started to drive the threaded rod 13 to rotate, so that the cross plate 41 slides downward until the lower end surface of the L-shaped rod 11 is flush with the lower end of the baffle 15, and at this time the two baffles 1 The distance between the two ends of the cylinder 10 and the two ends of the cylinder 10 is the smallest, and then the motor 1 6 is used to drive the threaded rod 2 44 to rotate, so that the lifting plates 7 on both sides slide on the left slide rail 5 and the right slide rail 4 respectively, and descend, so that the L-shaped rod 11 extends into the inside of the ejection tube 10, and the multiple push rods 12 are aligned with the multiple through holes 45 in the same row, and then the motor 7 40 is started to drive the connecting rod 3 42 to rotate, and under the action of the connecting rod 43, the L-shaped rods 11 on both sides slide on the cross plate 41 at the same time and move away from each other, so that the push rod 12 can pass through the through hole 45 to align the through hole 45. 5, the raw materials adhering to and blocking the hole wall are pushed, so that the raw materials fall into the kettle body 1, and when the push rod 12 passes through the through hole 45, its end may still be attached with some raw materials, so when the push rod 12 passes through the through hole 45, the electric push rod 38 is started and drives the scraper 36 to descend. When the scraper 36 descends, its edge can form a scraping with the end of the push rod 12, scraping off the raw materials adhering to the end of the push rod 12, further promoting the falling of the raw materials, and then the push rod 12 is reset, and then the throwing tube 10 is driven to rotate a certain angle, so that the lower A row of through holes 45 is aligned with the push rod 12, and then the above operation is repeated to push off the raw materials attached to the hole walls of the multiple through holes 45, thereby avoiding the situation where the raw materials are blocked at the through holes 45, affecting the amount of raw material added and the subsequent throwing efficiency. In addition, after the push rod 12 passes through the through holes 45 and before it is reset, the raw materials attached to the end of the push rod 12 can be scraped off, further promoting the falling of the raw materials, and also avoiding the situation where the raw materials attached to the end of the push rod 12 fall into the throwing tube 10 again when the push rod 12 is reset, and the recycling effect is good. When it is necessary to push off the raw materials attached to the hole wall of the through hole 45, and there are large pieces of raw materials and impurities remaining in the ejection tube 10, if the L-shaped rod 11 directly enters the ejection tube 10 and is pushed by the push rod 12, the push rod 12 may squeeze the large pieces of raw materials or impurities into the through hole 45. If the impurities are hard objects such as metal or stone, the ejection tube 10 and the through hole 45 may be deformed, affecting the filtering effect. In addition, the large pieces of raw materials may be broken when squeezed. and scatter into the inside of the throwing-out tube 10, which makes it troublesome to collect the bulk raw materials again, and it is also troublesome to take out the bulk raw materials and impurities from the throwing-out tube 10 before clearing the through hole 45 each time; therefore, when the above situation occurs, the L-shaped rod 11 is first raised to the highest point, and then the motors 5 27 on both sides are used to drive the connecting rod 1 30 to rotate, and under the cooperation of the connecting rod 1 30 and the connecting rod 2 31, the sliding rod 1 29 slides on the limiting plate 28, so that the outer side of the baffle 1 25 The edge of the second baffle plate 26 is flush with the edge of the inner cavity of the throwing cylinder 10, and then the baffle plate 25 is driven down and enters into the throwing cylinder 10, and the outer edge of the baffle plate 25 is in contact with the inner edge of the throwing cylinder 10, so that the bulk raw materials and impurities in contact with the edge of the inner cavity of the throwing cylinder 10 can be pushed away from the edge of the inner cavity of the throwing cylinder 10, and because the upper end of the throwing cylinder 10 is an inclined surface, when the lower end of the baffle plate 26 contacts the upper end of the throwing cylinder 10, the end of one side of the baffle plate 26 is pressed against the throwing cylinder 10. The inner wall of the ejection tube 10 is fitted, the baffle plate 26 slides on the baffle plate 1 25, the slide bar 2 32 slides, and the spring 35 is compressed. When the lower end surfaces of the baffle plates 1 25 and the baffle plates 2 26 are fitted with the bottom of the inner cavity of the ejection tube 10, the motor 5 27 is used to drive the connecting rod 1 30 and the connecting rod 2 31 to rotate, so that the baffle plate 1 25 is away from the inner wall of the ejection tube 10, and the baffle plate 2 26 is tightly attached to the inner wall of the ejection tube 10 under the action of the spring 35, so that the baffle plate 1 25, the baffle plate 2 26 and the ejection tube 10 cooperate with each other. A fence without raw materials and impurities is formed. At this time, the L-shaped rod 11 is driven down to enter the fence, and then the push rod 12 is driven to move to perform the dredging work, so that the push rod 12 can be prevented from squeezing the large pieces of raw materials or impurities into the through hole 45, causing the deformation of the ejection tube 10 and the through hole 45, affecting the ejection effect, and also preventing the large pieces of raw materials from being squeezed and crushed and scattered into the inside of the ejection tube 10, which makes it more troublesome to collect the large pieces of raw materials. There is no need to clean the inside of the ejection tube 10 before each dredging work. After multiple dredging works, the large pieces of raw materials and impurities can be collected and processed uniformly; then, the rotation of the ejection tube 10 can be coordinated to dredge multiple groups of through holes 45; Therefore, by utilizing the self-draining filtering and feeding mechanism, small pieces of raw materials can be thrown out into the kettle body 1 through the through hole 45 under the action of centrifugal force, while large pieces of raw materials and impurities will be blocked by the through hole 45. The blocked large pieces of raw materials can be collected and re-crushed and added to the kettle body 1 again. By throwing the raw materials into the kettle body 1, the raw materials can be evenly distributed in the kettle body 1, avoiding the situation that the raw materials are in the same position every time they enter the kettle body 1, thereby affecting the raw material mixing effect, and also avoiding the situation that large pieces of raw materials and impurities enter the kettle body 1 together and mix with the raw materials, affecting the purity of the final product. In addition, when the raw materials adhere to the inner wall of the through hole 45 and block the through hole 45, the pushing The rod 12 passes through the plurality of through holes 45 in sequence to push down the raw materials attached to the through holes 45, thereby avoiding the situation where the raw materials are blocked at the through holes 45 and affect the amount of raw material added and the subsequent throwing-out efficiency. Moreover, after the pushing rod 12 passes through the through holes 45 and before it is reset, the raw materials attached to the end of the pushing rod 12 can be scraped off, further promoting the falling of the raw materials, and also avoiding the situation where the raw materials attached to the end of the pushing rod 12 fall into the throwing-out tube 10 again when the pushing rod 12 is reset, so that the recycling effect is good. Moreover, when it is necessary to push down the raw materials attached to the hole wall of the through hole 45 and there are large pieces of raw materials and impurities remaining in the throwing-out tube 10, before pushing, with the cooperation of the baffle 1 25, the baffle 2 26 and the throwing-out tube 10, An enclosure without raw materials and impurities is formed. At this time, the L-shaped rod 11 is driven down to enter the enclosure, and then the push rod 12 is driven to move to perform the dredging work. This can prevent the push rod 12 from squeezing large pieces of raw materials or impurities into the through hole 45, causing deformation of the ejection tube 10 and the through hole 45, affecting the ejection effect. In addition, it also prevents large pieces of raw materials from being squeezed and crushed and scattered into the inside of the ejection tube 10, resulting in more troublesome collection of large pieces of raw materials. There is no need to clean the inside of the ejection tube 10 before each dredging work. After multiple dredging works, the large pieces of raw materials and impurities can be collected and processed uniformly.

[0026] Working principle: add the raw materials into the throwing cylinder 10, and then use the motor 24 to drive the cylinder cover 19 to rotate to close the upper end of the throwing cylinder 10, and then start the motor 22 to drive the gear 21 to rotate, so that the ring gear 20 and the throwing cylinder 10 can continue to rotate. Under the action of centrifugal force, small pieces of raw materials can be thrown into the kettle body 1 through the through hole 45, while large pieces of raw materials and impurities will be blocked by the through hole 45. The blocked large pieces of raw materials can be collected and re-crushed in the future, and then added to the kettle body 1 again. By throwing the raw materials into the kettle body 1, the raw materials can be evenly distributed in the kettle body 1, avoiding the problem of raw materials being scattered everywhere. After entering the kettle body 1 for the first time, they are all at the same position, which affects the mixing effect of the raw materials. It also avoids the situation where large pieces of raw materials and impurities enter the kettle body 1 together and mix with the raw materials, affecting the purity of the final product. When the raw materials are added into the kettle body 1, the motor 18 is started to drive the sprocket 17 on one side to rotate, and the chain 16 cooperates to make the multiple sprockets 17 and the stirring shaft 8 rotate at the same time, so that the multiple stirring blades 9 rotate at the same time and stir the raw materials. The raw materials that have completed the reaction can be discharged from the discharge port (2), so that the mixing efficiency of the raw materials is accelerated under the action of the simultaneous rotation of the multiple stirring blades 9.During the raw material throwing process, the raw material may adhere to the inner wall of the through hole 45 and block the through hole 45, which not only affects the amount of raw material added, but also affects the subsequent throwing of the raw material. Therefore, when the through hole 45 wall is attached with raw material, the cylinder cover 19 can be driven to open. If there is no large piece of raw material and impurities in the throwing cylinder 10 at this time, the motor 6 39 can be started to drive the threaded rod 13 to rotate, so that the cross plate 41 slides downward until the lower end surface of the L-shaped rod 11 is flush with the lower end of the baffle 1 25, and the distance between the two baffles 25 is the smallest. Then, the motor 1 6 is used to drive the threaded rod 2 44 to rotate, so that the lifting plates 7 on both sides slide on the left slide rail 5 and the right slide rail 4 respectively, and descend, so that The L-shaped rod 11 extends into the inside of the ejection tube 10, and the multiple push rods 12 are aligned with the multiple through holes 45 in the same row, and then the motor 7 40 is started to drive the connecting rod 3 42 to rotate. Under the action of the connecting rod 43, the L-shaped rods 11 on both sides slide on the cross plate 41 at the same time and move away from each other, so that the push rod 12 can pass through the through hole 45 to push the raw materials attached to and blocked by the hole wall of the through hole 45, so that the raw materials fall into the kettle body 1. In addition, when the push rod 12 passes through the through hole 45, part of the raw materials may still be attached to its end. Therefore, after the push rod 12 passes through the through hole 45, the electric push rod 38 is started and drives the scraper 36 to descend. When the scraper 36 descends, its edge can form a scraper with the end of the push rod 12. The raw materials attached to the walls of the multiple through holes 45 can be pushed off, thereby avoiding the situation where the raw materials are blocked at the through holes 45 and affect the amount of raw materials added and the subsequent throwing-out efficiency. In addition, after the push rod 12 passes through the through holes 45 and before it is reset, the raw materials attached to the end of the push rod 12 can be scraped off, thereby further promoting the falling of the raw materials and avoiding the situation where the raw materials attached to the end of the push rod 12 fall into the throwing-out tube 10 again when the push rod 12 is reset. The recycling effect is good. When the raw materials attached to the hole wall of the through hole 45 are pushed off and there are large pieces of raw materials and impurities remaining in the ejection tube 10, if the L-shaped rod 11 directly enters the ejection tube 10 and is pushed by the push rod 12, the push rod 12 may squeeze the large pieces of raw materials or impurities into the through hole 45. If the impurities are hard objects such as metals or stones, the ejection tube 10 and the through hole 45 may be deformed, affecting the filtering effect. Moreover, when the large pieces of raw materials are squeezed, they may break and scatter into the ejection tube 10, making it more troublesome to collect the large pieces of raw materials. It is also more troublesome to take out the large pieces of raw materials and impurities from the ejection tube 10 before clearing the through hole 45 each time.Therefore, when the above situation occurs, the L-shaped rod 11 is first raised to the highest point, and then the motors 5 27 on both sides are used to drive the connecting rod 1 30 to rotate. Under the cooperation of the connecting rod 1 30 and the connecting rod 2 31, the sliding rod 1 29 is made to slide on the limit plate 28, so that the outer edge of the baffle 1 25 is flush with the inner edge of the ejection tube 10, and then the baffle 1 25 is driven down and enters the ejection tube 10, and the outer edge of the baffle 1 25 is in contact with the inner edge of the ejection tube 10, so that the large pieces of raw materials and impurities in contact with the inner edge of the ejection tube 10 can be pushed away from the inner edge of the ejection tube 10, and because the upper end of the ejection tube 10 is an inclined surface Therefore, when the lower end of the second baffle plate 26 contacts the upper end of the throwing tube 10, under the effect of extrusion, one end of the second baffle plate 26 will fit with the inner wall of the throwing tube 10, the second baffle plate 26 slides on the first baffle plate 25, the second slide bar 32 slides, and the spring 35 is compressed. When the lower end surfaces of the first baffle plate 25 and the second baffle plate 26 fit with the bottom of the inner cavity of the throwing tube 10, the motor 5 27 is used to drive the connecting rod 1 30 and the connecting rod 2 31 to rotate, so that the first baffle plate 25 is away from the inner wall of the throwing tube 10, and the second baffle plate 26 is tightly attached to the inner wall of the throwing tube 10 under the effect of the spring 35. Then, with the cooperation of the first baffle plate 25, the second baffle plate 26 and the throwing tube 10, A fence without raw materials and impurities is formed. At this time, the L-shaped rod 11 is driven down to enter the fence, and then the push rod 12 is driven to move to perform the dredging work, so that the push rod 12 can be prevented from squeezing the large pieces of raw materials or impurities into the through hole 45, causing the deformation of the ejection tube 10 and the through hole 45, affecting the ejection effect, and also preventing the large pieces of raw materials from being squeezed and crushed and scattered into the inside of the ejection tube 10, which makes it more troublesome to collect the large pieces of raw materials. There is no need to clean the inside of the ejection tube 10 before each dredging work. After multiple dredging works, the large pieces of raw materials and impurities can be collected and processed uniformly; then, the rotation of the ejection tube 10 can be coordinated to dredge multiple groups of through holes 45; Therefore, by utilizing the self-draining filtering and feeding mechanism, small pieces of raw materials can be thrown out into the kettle body 1 through the through hole 45 under the action of centrifugal force, while large pieces of raw materials and impurities will be blocked by the through hole 45. The blocked large pieces of raw materials can be collected and re-crushed and added to the kettle body 1 again. By throwing the raw materials into the kettle body 1, the raw materials can be evenly distributed in the kettle body 1, avoiding the situation that the raw materials are in the same position every time they enter the kettle body 1, thereby affecting the raw material mixing effect, and also avoiding the situation that large pieces of raw materials and impurities enter the kettle body 1 together and mix with the raw materials, affecting the purity of the final product. In addition, when the raw materials adhere to the inner wall of the through hole 45 and block the through hole 45, the pushing The rod 12 passes through the plurality of through holes 45 in sequence to push down the raw materials attached to the through holes 45, thereby avoiding the situation where the raw materials are blocked at the through holes 45 and affect the amount of raw material added and the subsequent throwing-out efficiency. Moreover, after the pushing rod 12 passes through the through holes 45 and before it is reset, the raw materials attached to the end of the pushing rod 12 can be scraped off, further promoting the falling of the raw materials, and also avoiding the situation where the raw materials attached to the end of the pushing rod 12 fall into the throwing-out tube 10 again when the pushing rod 12 is reset, so that the recycling effect is good. Moreover, when it is necessary to push down the raw materials attached to the hole wall of the through hole 45 and there are large pieces of raw materials and impurities remaining in the throwing-out tube 10, before pushing, with the cooperation of the baffle 1 25, the baffle 2 26 and the throwing-out tube 10, An enclosure without raw materials and impurities is formed. At this time, the L-shaped rod 11 is driven down to enter the enclosure, and then the push rod 12 is driven to move to perform the dredging work. This can prevent the push rod 12 from squeezing large pieces of raw materials or impurities into the through hole 45, causing deformation of the ejection tube 10 and the through hole 45, affecting the ejection effect. In addition, it also prevents large pieces of raw materials from being squeezed and crushed and scattered into the inside of the ejection tube 10, resulting in more troublesome collection of large pieces of raw materials. There is no need to clean the inside of the ejection tube 10 before each dredging work. After multiple dredging works, the large pieces of raw materials and impurities can be collected and processed uniformly.
