Description

Technical Field

[0001] The utility model relates to the technical field of reaction kettles, in particular to a high-pressure reaction kettle. Background Art

[0002] When the pressure inside the high-pressure reaction kettle is high during the reaction, it is difficult to add new materials during the reaction process. The following is a high-pressure reaction kettle that can add materials midway proposed in the prior art:

[0003] The patent with the application number 202420064611.1 discloses a high-pressure reaction kettle. One side of the top of its valve cover is provided with a material adding cylinder. The upper end of one side of the material adding cylinder is communicated with an inclined upward feeding pipe. The bottom end of the inner wall of the material adding cylinder is slidably connected with a conical lifting piston plate, and the conical lifting piston plate is controlled to lift by a push rod motor protruding from the upper end of the top of the material adding cylinder, so as to realize the opening and closing between the material adding cylinder and the main body of the high-pressure reaction kettle, so that the materials put into the material adding cylinder through the feeding pipe and falling on the conical lifting piston plate can be selectively slid or fallen into the main body of the high-pressure reaction kettle; In addition, a second sealing cover is fixedly arranged at the central position of the outer wall of the top of the valve cover. A vertically downward motor is fixedly arranged on the inner wall of the second sealing cover. The output shaft of the motor is connected with a rotating rod and the rotating rod extends into the main body of the high-pressure reaction kettle. Stirring paddles are fixedly arranged on the outer wall of the rotating rod at equal distances; Furthermore, a feeding valve is fixedly arranged on the feeding pipe, and the material adding cylinder and the main body of the high-pressure reaction kettle are communicated through a balance pipe, and a balance valve is installed on the balance pipe.

[0004] Although the high-pressure reaction kettle in the above patent is convenient to add materials at any time during the reaction process, the material adding channel is easy to be blocked. Specifically, on the one hand, the added materials are easy to accumulate on the side of the material adding cylinder close to the feeding pipe, resulting in the outlet of the feeding pipe being blocked quickly, which leads to the subsequent material adding being unsmooth or failed, and finally the amount of materials added at one time is severely limited and the storage space utilization of the material adding cylinder is insufficient; On the other hand, the feeding pipe is also easy to be blocked due to the properties of the added materials, etc., resulting in a slow material adding speed and seriously affecting the production efficiency. Improvement is needed. Summary of the Utility Model

[0005] Aiming at the deficiencies in the prior art, the utility model provides a high-pressure reaction kettle, which solves the problems of easy accumulation and blockage during material addition in the working process of the high-pressure reaction kettle in the prior art, resulting in a limited amount of materials added at one time, insufficient utilization of the storage space, and a slow material adding speed.

[0006] According to an embodiment of the present invention, a high-pressure reactor comprises a reactor body with an opening at the top and a reactor cover detachably mounted on the top of the reactor body, a feeding cylinder is protruding from one side of the top of the reactor cover, the top of the feeding cylinder is closed and the bottom of the feeding cylinder has an opening and closing mechanism, a discharge pipe connected to the feeding cylinder is provided at the upper end of one side, the discharge pipe is arranged obliquely upward and a discharge valve is provided on the discharge pipe, and the reactor body further comprises:

[0007] There are two knocking rods, and the two knocking rods are matched with the feeding tube and the feeding cylinder in a one-to-one manner;

[0008] A two-way reciprocating motion mechanism is connected to two knocking rods, and is used to drive one of the knocking rods to knock reciprocally on the material adding cylinder and drive the other knocking rod to knock reciprocally on the material discharge pipe.

[0009] The technical principle of the present utility model is: the two knocking rods correspond to the discharge pipe and the feeding cylinder one by one, and the bidirectional reciprocating motion mechanism is connected to the two knocking rods, which is used to drive one of the knocking rods to knock the feeding cylinder back and forth and drive the other knocking rod to knock the discharge pipe back and forth, that is, a continuous vibration effect is formed on the feeding cylinder and the discharge pipe to avoid material accumulation and blockage in the discharge pipe and the feeding cylinder.

[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] 1. Good anti-accumulation and clogging effect. By adopting a two-way reciprocating motion mechanism, both the feeding cylinder and the discharge pipe are continuously vibrated. On the one hand, the material in the discharge pipe is forced to pass through the discharge pipe quickly and fall into the feeding cylinder, thereby preventing the material from accumulating and clogging in the discharge pipe; on the other hand, the material accumulated on one side of the feeding cylinder near the discharge pipe is forced to fall into the space on the opposite side, thereby preventing the discharge pipe outlet from being blocked too quickly and making effective use of the storage space in the feeding cylinder. Ultimately, the amount of material added at one time is effectively increased, the storage space is effectively utilized, and the material addition speed is increased, effectively improving production efficiency.

Specific embodiments

[0021] The technical solutions in the present invention will be further described below with reference to the drawings and embodiments.

[0022] As Figures 1 - 8As shown in the figure, an embodiment of the present utility model provides a high-pressure reactor, which includes a reactor body 100 with an opening at the top and a reactor cover 200 detachably covering the top of the reactor body 100. One side of the top of the reactor cover 200 is convexly provided with a feeding cylinder 300. The top end of the feeding cylinder 300 is closed and its bottom end is provided with an opening and closing mechanism. One side of the upper end of the feeding cylinder 300 is provided with a feeding pipe 330 communicating with it. The feeding pipe 330 is inclined upward and is provided with a feeding valve 340 thereon; when adding materials during the working process of the high-pressure reactor, first open the feeding valve 340, put the materials into the feeding pipe 330, and then the materials fall into the feeding cylinder 300. After the amount of materials in the feeding cylinder 300 meets the requirements, close the feeding valve 340, open the opening and closing mechanism, and the materials will fall from the feeding cylinder 300 into the reactor body 100. After all the materials have fallen into the reactor body 100, close the opening and closing mechanism; however, during the above process, the materials are likely to accumulate and block on one side of the feeding pipe 330 or the feeding cylinder 300, resulting in problems such as limited amount of materials added at one time, insufficient utilization of the storage space, and slow material addition speed; to solve this problem, the high-pressure reactor of the present utility model further includes a knocking rod 440 and a bidirectional reciprocating motion mechanism. There are two knocking rods 440, and the two knocking rods 440 are respectively and correspondingly matched with the feeding pipe 330 and the feeding cylinder 300; the bidirectional reciprocating motion mechanism is connected to the two knocking rods 440 and is used to drive one of the knocking rods 440 to reciprocally knock the feeding cylinder 300 and drive the other knocking rod 440 to reciprocally knock the feeding pipe 330. In the present utility model, by adopting the bidirectional reciprocating motion mechanism to form a continuous vibration effect on both the feeding cylinder 300 and the feeding pipe 330, on the one hand, it promotes the materials in the feeding pipe 330 to quickly pass through the feeding pipe 330 and fall into the feeding cylinder 300 to avoid the accumulation and blockage of materials in the feeding pipe 330; on the other hand, it promotes the materials accumulated on one side of the feeding cylinder 300 close to the feeding pipe 330 to fall into the opposite side space, so that the outlet of the feeding pipe 330 is not easily blocked too quickly and the storage space in the feeding cylinder 300 can be effectively utilized; ultimately, the amount of materials added at one time is effectively increased, the storage space is effectively utilized, and the material addition speed is increased, effectively improving the production efficiency.

[0023] As Figures 3 - 5 shown, according to another embodiment of the present utility model, the bidirectional reciprocating motion mechanism includes a placement table 410 and a telescopic device; the placement table 410 is fixedly connected to the outer wall of the feeding cylinder 300; the telescopic device is slidably connected to the placement table 410 and its telescopic end is connected to one of the knocking rods 440 arranged towards the feeding cylinder 300, and the non-telescopic part of the telescopic device is connected to the other knocking rod 440 arranged towards the feeding pipe 330. An elastic resetting member is connected between the telescopic device and the end of the placement table 410 away from the feeding cylinder 300, and the elastic resetting member is arranged along the telescopic direction of the telescopic device.

[0024] Based on the above solution, asFigures 3 - 6 As shown in the figure, a limiting chute 450 extending along the telescopic direction of the telescopic device is formed at the top of the placing table 410. A slider 460 is arranged in the limiting chute 450 in a matching manner, and the top of the slider 460 is connected to the bottom of the telescopic device. The elastic resetting member is connected between the slider 460 and the side of the limiting chute 450 away from the material adding cylinder 300.

[0025] Specifically: The material adding cylinder 300 is generally vertically arranged, and the feeding pipe 330 communicated therewith is preferably arranged with the lower section inclined upward and the upper section vertically upward (i.e., forming a corner). Based on this, the placing table 410 is preferably arranged on the outer wall of the material adding cylinder 300 corresponding to the lower part of the feeding pipe 330; the telescopic device is preferably a telescopic motor 420, and the telescopic motor 420 is slidably connected to the placing table 410 in the horizontal direction, and its telescopic shaft is arranged towards the material adding cylinder 300; correspondingly, the knocking rod 440 cooperating with the feeding pipe 330 is preferably arranged towards the vertical part of the feeding pipe 330. More preferably, it is arranged near the corner of the feeding pipe 330, and when the elastic resetting member (preferably a spring 430) is in the initial state, one end thereof abuts against the outer wall of the feeding pipe 330; the shape of the limiting chute 450 is relatively flexible, and its longitudinal section is preferably in a "convex" shape. Correspondingly, the longitudinal section of the slider 460 is also in a "convex" shape.

[0026] In this embodiment, the connection between the placing table 410 and the outer wall of the material adding cylinder 300 can maximize the space saving of the kettle lid 200; in addition, since the telescopic shaft of the telescopic device is arranged towards the material adding cylinder 300, the knocking rod 440 cooperating with the material adding cylinder 300 is equivalent to extending a part of the telescopic shaft along its telescopic direction; the elastic resetting member is connected between the telescopic device and the placing table 410, which can not only make the telescopic device stable at the initial position when not working, but also give a certain acting force when the knocking rod 440 (cooperating with the material adding cylinder 300) touches the material adding cylinder 300 to ensure the knocking effect; the arrangement mode of the other knocking rod 440 cooperating with the feeding pipe 330 makes the knocking surface larger on the one hand, the knocking point is closer to the corner where blockage is more likely to occur on the other hand, and on the third hand, it can ensure that the knocking rod contacts the feeding pipe 330 when the elastic resetting member is compressed and then reset, thereby finally ensuring the knocking effect on the feeding pipe 330. In summary, the cooperation between the telescopic device and the elastic resetting member in this embodiment is ingenious. If the telescopic speed of the telescopic device is further controlled to be relatively fast and the time interval between every two telescopic operations is controlled to be appropriate, the elastic force of the elastic resetting member can be better utilized to perform multiple knocks on the feeding pipe 330 in each knocking cycle, thereby improving the knocking effect and better saving energy; at the same time, the structure is simple, the precision requirement is not high, and it is easy to control; in addition, the sliding of the telescopic device is limited in the limiting chute 450 by the slider 460, which ensures the stability of the knocking direction, thereby further ensuring the knocking effect.

[0027] When this embodiment is in use:

[0028] Initial state ( Figure 3 and Figure 4 ): The telescopic motor 420 is in the initial state. At this time, among the two knocking rods 440, one is at a certain distance from the feeding cylinder 300, and the other abuts against the vertical part of the blanking pipe 330; at the same time, the spring 430 is in a free state;

[0029] Knocking the feeding cylinder 300: Turn on the telescopic motor 420, and its telescopic shaft extends to drive the knocking rod 440 on the telescopic shaft to move in the direction close to the feeding cylinder 300. When the knocking rod 440 abuts against the outer wall of the feeding cylinder 300, it produces a knocking vibration effect on the outer wall of the feeding cylinder 300;

[0030] Intermediate state ( Figure 5 ): Then the telescopic shaft of the telescopic motor 420 continues to extend a certain distance. The reaction force of the outer wall of the feeding cylinder 300 on the telescopic motor 420 causes the whole telescopic motor 420 to move in the direction away from the feeding cylinder 300. On the one hand, the telescopic motor 420 drives the knocking rod 440 cooperating with the blanking pipe 330 to leave the outer wall of the blanking pipe 330, and on the other hand, it drives the slider 460 to slide in the direction away from the feeding cylinder 300, thereby compressing the spring 430 and storing elastic potential energy;

[0031] Knocking the blanking pipe 330: The telescopic shaft of the telescopic motor 420 retracts (the retraction speed can be controlled to be relatively fast), so that the spring 430 extends to reset. When the knocking rod 440 cooperating with the feeding cylinder 300 is about to leave the outer wall of the feeding cylinder 300, the spring 430 resets (returns to its original state), and at the same time, the knocking rod 440 cooperating with the blanking pipe 330 is about to re-abut against the outer wall of the blanking pipe 330; at this time, the telescopic shaft of the telescopic motor 420 continues to retract; at the moment of reset, the elastic potential energy stored by the spring 430 in the previous process is converted into kinetic energy, so that the slider 460 connected thereto vibrates, and the slider 460 drives the telescopic motor 420 and the two knocking rods 440 connected to the telescopic motor 420 to vibrate; since the knocking rod 440 cooperating with the feeding cylinder 300 quickly moves away from the feeding cylinder 300 as the telescopic shaft of the telescopic motor 420 continues to retract, it cannot continue to knock the feeding cylinder 300; while the knocking rod 440 cooperating with the blanking pipe 330 forms multiple knocking vibration effects on the blanking pipe 330 along with the vibration (preferably, the telescopic shaft of the telescopic motor 420 stops retracting after retracting to the initial state in this process), until the spring 430 returns to the free state and stops. At this time, one knocking cycle is completed;

[0032] Entering the next knocking cycle: After a certain period of time, the telescopic shaft of the telescopic motor 420 extends again, and thus enters the next knocking cycle, so as to form a continuous vibration effect on both the feeding cylinder 300 and the blanking pipe 330.

[0033] AsFigure 3 、 Figure 7 and Figure 8 As shown, according to another embodiment of the present invention, a high-pressure reactor is provided with a stirring rod 510 that is rotatable in the reactor body 100, and the stirring rod 510 is also connected to a striking vibration mechanism, which rotates with the stirring rod 510 to intermittently strike the opening and closing mechanism when the opening and closing mechanism is in an open state.

[0034] Specifically:

[0035] Generally, the materials in the high-pressure reactor need to be continuously stirred during the reaction process, so a stirring device is generally provided inside the reactor body 100, and the stirring device is usually controlled by a rotary motor 520. The rotary motor 520 is preferably provided on the top of the reactor cover 200, that is, a rotary motor sealing cover is protruding outward at the central position of the top of the reactor cover 200, and the rotary motor 520 can be placed inside it. The output shaft of the rotary motor 520 extends into the reactor body 100 and is connected to the stirring rod 510. The stirring section of the stirring rod 510 extending into the material in the reactor body 100 is usually provided with a stirring paddle, and the connecting section of the stirring rod 510 located above the stirring paddle can be connected to the striking vibration mechanism. The cam 320 is connected to the bottom of the cam 320 and is in a closed position, so that the cam 320 is in a closed position and the cam 320 is in a closed position. In summary, when the conical piston block 310 drops to the corresponding height of the striking vibration mechanism, the striking vibration mechanism that rotates with the stirring rod 510 can intermittently knock it to achieve a vibration effect, thereby accelerating the slippage of the material on the conical piston block 310 and avoiding the adhesion and accumulation of the material on the conical piston block 310 and the output shaft of the lifting motor 320 as much as possible, thereby ensuring the accuracy of the material addition amount; in addition, the striking vibration mechanism is installed on the stirring rod 510, which fully saves space and energy.

[0036] Further, such as Figure 3 、 Figure 7 and Figure 8As shown, the hitting and vibrating mechanism includes an elastic hitting rod 610. One end of the elastic hitting rod 610 is connected to the stirring rod 510, and when the opening and closing mechanism is in the open state, it is on the rotation radius of the other end of the elastic hitting rod 610; the elasticity and hardness of the elastic hitting rod 610 should be appropriate to ensure the hitting effect.

[0037] Based on the above solution, as Figure 3 、 Figure 7 and Figure 8 shown, the high-pressure reactor further includes a transmission component. The transmission component is arranged at the bottom end of the opening and closing mechanism and is on the rotation radius of the elastic hitting rod 610. Further, as Figure 3 、 Figure 7 and Figure 8 shown, the transmission component includes a connecting frame and a transmission rod 620. The connecting frame includes a support foot connecting plate 630 and a plurality of support feet 640 connected between the support foot connecting plate 630 and the bottom of the opening and closing mechanism. Specifically, the number of support feet 640 is preferably 3, and the 3 support feet 640 are respectively connected to the bottom end of the conical piston block 310 in an equilateral triangle; one end of the transmission rod 620 is connected to the bottom end of the support foot connecting plate 630 and is on the rotation radius of the elastic hitting rod 610 when the opening and closing mechanism is in the open state; the structure of this transmission component is simple, and it can ensure the diversity and uniformity of the force application points, further improving the vibration effect.

[0038] As Figures 1 - 3 and Figure 7 shown, according to another embodiment of the present invention, the high-pressure reactor further includes an air extraction device. The air extraction device includes an air extraction pump 710, an air inlet pipe 720, and an air outlet pipe 730; the air extraction pump 710 is arranged on the top of the kettle lid 200. Based on the foregoing preferred solution, to save the space of the kettle lid 200, the air extraction pump 710 can be arranged on the top of the rotating motor seal cover; the air inlet pipe 720 is arranged between the air inlet of the air extraction pump 710 and the feeding cylinder 300, and the air outlet pipe 730 is arranged at the air outlet of the air extraction pump 710. Further, the air extraction device further includes a filtering component. The filtering component is arranged in the air inlet pipe 720. Preferably, the filtering substance in the filtering component is activated carbon 740. Thus, the chemical gas entering the feeding cylinder 300 during the material adding process can be directly discharged through the air extraction device for post-treatment, or can be filtered in the air extraction device and then discharged, so as to avoid the escape of toxic gas in the feeding cylinder 300 and cause harm to the staff when opening the feeding valve 340 to add materials into the feeding pipe 330.

[0039] Furthermore, considering the relatively high pressure inside the high-pressure reactor, to facilitate the addition of materials and ensure that the lifting motor 320 can work more smoothly, a connecting pipe 810 is provided between one side of the feeding cylinder 300 and the inner wall of the kettle cover 200, and a pneumatic balance valve 820 is provided on the connecting pipe 810; correspondingly, pressure gauges 830 can be provided on the side wall of the feeding cylinder 300 and the side wall of the cylinder body to facilitate the observation of the air pressure in the corresponding space and avoid accidents. Additionally, preferably, this embodiment is a further optimization based on the foregoing embodiments.

[0040] During use:

[0041] Initial state: The kettle cover 200 is closed; the rotating motor 520 drives the stirring rod 510 to rotate continuously; the lifting motor 320 is not started and the conical piston block 310 connected to its lower end is stationary at the bottom position inside the feeding cylinder 300, that is, the bottom opening of the feeding cylinder 300 is in a closed state ( Figure 3 ); the feeding valve 340 and the pneumatic balance valve 820 are both in a closed state;

[0042] Putting and storing materials into the feeding cylinder 300: Open the feeding valve 340 and the telescopic motor 420, put materials into the feeding pipe 330, and the materials fall into the feeding cylinder 300; during this process, the telescopic motor 420 expands and contracts to drive the knocking rod 440 cooperating with the feeding cylinder 300 to reciprocally knock the feeding cylinder 300, and at the same time it cooperates with the spring 430 to drive another knocking rod 440 cooperating with the feeding pipe 330 to reciprocally knock the feeding pipe 330 ( Figure 4 and Figure 5 ; for the specific process, please refer to the above text), so as to form a vibration effect on both the feeding cylinder 300 and the feeding pipe 330. Thus, on the one hand, it promotes the rapid fall of the materials in the feeding pipe 330 to avoid accumulation and blockage, and on the other hand, it promotes the materials piled up on one side in the feeding cylinder 300 to move to the opposite side, so that the materials in the feeding cylinder 300 can evenly fill the corresponding storage space; after the materials are put in, after a certain period of time, close the feeding valve 340 and the telescopic motor 420;

[0043] Transferring materials into the kettle body 100: Open the pneumatic balance valve 820. At this time, the pressure inside the feeding cylinder 300 is the same as that inside the kettle body 100. Then open the lifting motor 320, and the output shaft of the lifting motor 320 extends to make the conical piston block 310 slide downwards. After the conical piston block 310 slides away from the feeding cylinder 300, the output shaft of the lifting motor 320 continues to extend to send the conical piston block 310 into the space surrounded by the kettle cover 200 and the kettle body 100. When the transmission rod 620 descends to the corresponding height of the elastic striking rod 610 ( Figure 7 and Figure 8) Turn off the lifting motor 320; at this time, the bottom opening of the material adding cylinder 300 is opened, the material adding cylinder 300 is communicated with the inside of the kettle body 100, and the materials in the material adding cylinder 300 fall into the kettle body 100. At the same time, when the elastic striking rod 610 touches the transmission rod 620 during rotation with the stirring rod 510, it will bend around and continue to rotate, forming a striking and vibrating effect on the transmission rod 620. This striking and vibrating effect is then transmitted to the conical piston block 310 through the support foot connecting plate 630 and the support foot 640 in sequence, prompting the materials adhered to the conical piston block 310 and the output shaft of the lifting motor 320 to fall off as soon as possible, so as to prompt the materials in the material adding cylinder 300 to be drained as soon as possible;

[0044] Restore the initial state: After a certain period of time, start the lifting motor 320, and the output shaft of the lifting motor 320 contracts to drive the conical piston block 310 to rise and slide into the material adding cylinder 300. At this time, the bottom of the material adding cylinder 300 is closed, and then the lifting motor 320 is turned off; finally, close the air pressure balance valve 820, and then turn on the air extraction pump 710 as needed to filter and extract the gas in the material adding cylinder 300.

[0045] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the purpose and scope of the technical solutions of the present invention, and they should all be covered by the scope of the claims of the present invention.
