Description

Technical Field

[0001] This utility model relates to the field of reaction vessel technology, specifically to a reaction vessel that can prevent materials from adhering to the inner wall. Background Technology

[0002] A reaction vessel is a container in which physical or chemical reactions occur. Through structural design and parameter configuration of the container, the heating, evaporation, cooling, and low-to-high-speed mixing functions required by the process can be achieved.

[0003] According to a publicized reactor for preventing material adhesion (publication number: CN220425351U), in the above application, the cylinder controls whether the rotating shaft and the take-up device are engaged or not. When the rotating shaft and the take-up device are engaged, the counterweight ring moves upward. When the rotating shaft and the take-up device are not engaged, the counterweight ring moves downward. Therefore, the counterweight ring moves up and down repeatedly to continuously clean the material adhering to the inside of the reactor.

[0004] However, in actual use, when the counterweight ring moves upward, it tends to push the material adhering to the inner wall of the reactor to the upper part of the inner wall. The distance between the stirring rod and the material at the upper part of the reactor is too far, which prevents the material pushed to the upper part of the inner wall of the reactor from continuing to react, resulting in insufficient reaction in the reactor. In view of this, we propose a reactor that can prevent material from adhering to the inner wall. Utility Model Content

[0005] The purpose of this invention is to provide a reaction vessel that can prevent materials from adhering to the inner wall, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a reaction vessel that prevents material from adhering to its inner wall, comprising an outer shell, a through-feed inlet on the outer wall of the outer shell, a through-feed outlet on the lower outer wall of the outer shell, a motor fixedly connected to the inner wall of the outer shell, a transmission rod fixedly connected to the output end of the motor, a stirring blade fixedly connected to the outer wall of the transmission rod, a scraper fixedly connected to the outer wall of the transmission rod, and a toggle assembly disposed inside the scraper, the toggle assembly comprising:

[0007] A roller is rotatably connected to one end of the scraper near the inner wall of the outer casing. A rotating gear is fixedly connected to the axis of the roller. A transmission gear meshes with the outer wall of the rotating gear. Both ends of the transmission gear mesh with the rotating gear. A reciprocating lead screw is fixedly connected to the axis of the rotating gear away from the roller.

[0008] A slide block is slidably connected to the outer wall of a reciprocating lead screw. A telescopic block is fixedly connected to the outer wall of the slide block. A trapezoidal groove is provided on the inner wall of the scraper. Slide rods are fixedly connected to both ends of the output end of the telescopic block. The slide rods slide on the inner wall of the trapezoidal groove.

[0009] Preferably, the scraper is provided with a sealing assembly inside. The sealing assembly includes a winding roller, the outer wall of which is fitted with a torsion spring. A sealing strip is fixedly connected to the outer wall of the winding roller. The outer wall of the sealing strip has a through-hole fixing groove so that the sealing strip can seal the opening of the scraper and prevent material from entering the opening.

[0010] Preferably, both ends of the sealing strip are fixedly connected to a winding roller, and a rotating shaft is provided at the axis of the winding roller. The torsion spring is sleeved on the outer wall of the rotating shaft, and the torsion springs on the winding rollers at both ends of the sealing strip are in opposite directions. The two sets of torsion springs can make the two sets of winding rollers rotate in opposite directions, so that the winding rollers can pull the sealing strip and make the sealing strip taut.

[0011] Preferably, the telescopic block is provided with a spring inside. One end of the spring is fixedly connected to the end of the telescopic block output near the inner wall of the telescopic block, and the other end of the spring is fixedly connected to the inner wall of the telescopic block. When the telescopic block moves to the upper end of the scraper, the slide rod moves on the inner wall of the trapezoidal groove. At this time, the telescopic block is driven by the spring to extend. When the telescopic block descends, it can scrape the material off the scraper.

[0012] Preferably, the outer wall of the scraper is provided with a groove, and the sealing strip is slidably connected on the inner wall of the groove. The size of the fixed groove is the same as the size of the output end of the telescopic block. The output end of the telescopic block passes through the fixed groove and the groove, so that when the telescopic block moves, the sealing strip can move along with it through the fixed groove. At this time, the winding roller rotates to wind and unwind the sealing strip, so that the sealing strip can always maintain a tight seal with the groove when the telescopic block moves.

[0013] Preferably, the roller contacts the inner wall of the housing, the transmission gear is rotatably connected to the inner wall of the scraper, and the end of the scraper near the housing is in contact with the inner wall of the housing, so that the scraper can fully scrape off the material adhering to the inner wall of the housing.

[0014] Preferably, the trapezoidal groove is configured as a right-angled trapezoid, and the end of the trapezoidal groove near the lower inner wall of the outer shell is configured as an inclined side. The distance between the parallel ends of the trapezoidal groove is consistent with the distance between the end of the telescopic block away from the slide block and the fixed groove. When the telescopic block moves to the lower end of the scraper, the slide rod moves on the inclined end of the trapezoidal groove, causing the slide rod to move from the side of the trapezoidal groove near the transmission rod to the other side parallel to it, thereby keeping the output end of the telescopic block contracted. At this time, the output end of the telescopic block is flush with the sealing strip.

[0015] Compared with the prior art, this utility model provides a reaction vessel that can prevent material from adhering to the inner wall, and has the following beneficial effects:

[0016] 1. This reactor, which prevents materials from adhering to the inner wall, uses a roller that rotates as the scraper moves, causing the rotating gear to rotate and drive the transmission gear to rotate the reciprocating screw. This causes the slide to move the telescopic block. When the telescopic block moves to the upper end of the scraper, it extends and descends to scrape the material off the scraper. When the telescopic block moves to the lower end of the scraper, its output end retracts, causing it to rise and prevent the material from being scraped to the top, thus allowing the material to react fully.

[0017] 2. This reactor, which prevents materials from adhering to the inner wall, allows the sealing strip to move along with the telescopic block when it moves, via the fixed groove. At this time, the winding roller rotates to wind and unwind the sealing strip, taut it, and thus the sealing strip maintains a seal on the slide groove when the telescopic block moves, preventing materials from entering the scraper from the slide groove and damaging the actuating components.

[0025] like Figures 1-6As shown, this utility model provides a technical solution: a reaction vessel that can prevent materials from adhering to the inner wall, including an outer shell 1, a through inlet 2 on the outer wall of the outer shell 1, a through outlet 3 on the lower outer wall of the outer shell 1, a motor 4 fixedly connected to the inner wall of the outer shell 1, a transmission rod 5 fixedly connected to the output end of the motor 4, a stirring blade 6 fixedly connected to the outer wall of the transmission rod 5, a scraper 7 fixedly connected to the outer wall of the transmission rod 5, and an actuating assembly 8 provided inside the scraper 7, the actuating assembly 8 including a roller 81, a rotating gear 82, a transmission gear 83, a reciprocating screw 84, a slide 85, a telescopic block 86, a slide rod 87, and a trapezoidal groove 88.

[0026] In one embodiment of this utility model, a roller 81 is rotatably connected to one end of the scraper 7 near the inner wall of the outer casing 1. A rotating gear 82 is fixedly connected to the axis of the roller 81. A transmission gear 83 meshes with the outer wall of the rotating gear 82. Both ends of the transmission gear 83 mesh with the rotating gear 82. A reciprocating screw 84 is fixedly connected to the axis of the rotating gear 82 away from the roller 81.

[0027] In one embodiment of this utility model, the slide block 85 is slidably connected to the outer wall of the reciprocating lead screw 84, and the outer wall of the slide block 85 is fixedly connected to the telescopic block 86. The inner wall of the scraper 7 is provided with a trapezoidal groove 88, and the two ends of the output end of the telescopic block 86 are fixedly connected to the slide rod 87, which slides on the inner wall of the trapezoidal groove 88.

[0028] In one embodiment of this utility model, valves are provided inside both the feed inlet 2 and the discharge outlet 3.

[0029] In addition, a sealing assembly 9 is provided inside the scraper 7. The sealing assembly 9 includes a winding roller 91. A torsion spring 92 is sleeved on the outer wall of the winding roller 91. A sealing strip 93 is fixedly connected to the outer wall of the winding roller 91. A through fixing groove 94 is opened on the outer wall of the sealing strip 93 so that the sealing strip 93 can seal the opening of the scraper 7 and prevent material from entering the opening and damaging the agitator 8.

[0030] In this embodiment of the present invention, both ends of the sealing strip 93 are fixedly connected to a take-up roller 91. A rotating shaft is provided at the center of the take-up roller 91, and a torsion spring 92 is sleeved on the outer wall of the rotating shaft. The torsion springs 92 on the take-up rollers 91 at both ends of the sealing strip 93 are in opposite directions. The two sets of torsion springs 92 can make the two sets of take-up rollers 91 rotate in opposite directions, so that the take-up rollers 91 can pull the sealing strip 93 and make the sealing strip 93 taut, thereby better sealing the scraper 7.

[0031] In an embodiment of this utility model, a spring is provided inside the telescopic block 86. One end of the spring is fixedly connected to the end of the output end of the telescopic block 86 near the inner wall of the telescopic block 86, and the other end of the spring is fixedly connected to the inner wall of the telescopic block 86. When the telescopic block 86 moves to the upper end of the scraper 7, the slide rod 87 moves on the inner wall of the trapezoidal groove 88. At this time, the telescopic block 86 is extended by the spring. When the telescopic block 86 descends, it can scrape the material on the scraper 7, and the material hanging off the scraper 7 can be stirred again.

[0032] In this embodiment of the invention, a groove is provided on the outer wall of the scraper 7, and the sealing strip 93 is slidably connected on the inner wall of the groove. The size of the fixed groove 94 is the same as the size of the output end of the telescopic block 86. The output end of the telescopic block 86 passes through the fixed groove 94 and the groove, so that when the telescopic block 86 moves, the sealing strip 93 can move along with it through the fixed groove 94. At this time, the winding roller 91 rotates to wind and unwind the sealing strip 93, so that the sealing strip 93 can maintain the seal on the groove at all times when the telescopic block 86 moves, so that the material will not enter the scraper 7 from the groove and damage the actuating component 8.

[0033] In the embodiments of this utility model, the roller 81 contacts the inner wall of the outer shell 1, the transmission gear 83 is rotatably connected to the inner wall of the scraper 7, and the end of the scraper 7 near the outer shell 1 is in contact with the inner wall of the outer shell 1, so that the scraper 7 can fully scrape off the material adhering to the inner wall of the outer shell 1, and the material can react fully.

[0034] In this embodiment of the utility model, the trapezoidal groove 88 is set as a right trapezoid, and the end of the trapezoidal groove 88 near the lower inner wall of the outer shell 1 is set as the inclined side. The distance between the parallel ends of the trapezoidal groove 88 is consistent with the distance between the end of the telescopic block 86 away from the slide 85 and the fixed groove 94. When the telescopic block 86 moves to the lower end of the scraper 7, the slide rod 87 moves on the inclined end of the trapezoidal groove 88, so that the slide rod 87 moves from the side of the trapezoidal groove 88 near the transmission rod 5 to the other side parallel to it, thereby keeping the output end of the telescopic block 86 contracted. At this time, the output end of the telescopic block 86 is flush with the sealing strip 93, so that the telescopic block 86 will not scrape the material to the top when it rises, making it difficult for the material to react fully.

[0035] In this invention, during use, the valve of the feed inlet 2 is opened to pour in the material for reaction. The motor 4 drives the transmission rod 5 to rotate, causing the stirring blade 6 to rotate accordingly to stir the material and accelerate the reaction process. As the transmission rod 5 rotates, the scraper 7 moves to scrape off the material on the inner wall of the outer casing 1. At this time, as the scraper 7 moves, the roller 81 rotates, causing a set of rotating gears 82 to rotate and drive the transmission gear 83 to rotate. This causes another set of rotating gears 82 to drive the reciprocating screw 84 to rotate, causing the slide 85 to move the telescopic block 86. When the telescopic block 86 moves to the upper end of the scraper 7, the slide rod 87 moves at the right-angle end of the trapezoidal groove 88. At this time, the telescopic block 86 is extended by the spring, causing the telescopic block 86 to descend and scrape the material off the scraper 7. When the telescopic block 86 moves to the lower end of the scraper 7, the slide rod 87 moves on the inclined end of the trapezoidal groove 88, causing the slide rod 87 to move from the side of the trapezoidal groove 88 closest to the transmission rod 5 to the other side parallel to it. This keeps the output end of the telescopic block 86 contracted, preventing the material from being scraped upwards when the telescopic block 86 rises, allowing the material to react fully. When the telescopic block 86 moves, the sealing strip 93 can move along with it through the fixed groove 94. At this time, the winding roller 91 rotates to wind and unwind the sealing strip 93, allowing it to be taut. This ensures that the sealing strip 93 can maintain a seal on the groove when the telescopic block 86 moves, preventing the material from entering the scraper 7 from the groove and damaging the actuating component 8. After the reaction is complete, the valve of the discharge port 3 is opened to remove the reacted material.

[0036] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
