Description
Technical Field
[0001] The utility model relates to the technical field of reaction kettles, in particular to a stable reaction kettle. Background Art
[0002] A reactor is a container that holds various raw materials for mixing and reaction. It is often used to complete processes such as sulfidation, nitration, hydrogenation, hydrocarbonization, polymerization, and condensation. Therefore, it is widely used in petroleum, chemical, rubber, pesticides, dyes, medicines, and food.
[0003] At present, various raw materials are put into the reactor, and then the temperature and pressure are increased or decreased, and the raw materials are stirred at the same time to react. However, this reactor generally has only one container and can only react once. After each reaction is completed, the obtained materials need to be taken out and put into another reactor for the next step of operation. During the transfer process, it is easy to be disturbed by various substances in the environment, thereby affecting the stability of the next reaction.
[0004] Therefore, it is necessary to propose a new technical solution to solve the above problems. Utility Model Content
[0005] In view of the deficiencies in the prior art, the utility model aims to provide a stable reactor.
[0006] The above technical purpose of the utility model is achieved through the following technical scheme: a stable reactor, comprising an upper shell and a lower shell connected as a whole and distributed up and down, and a cavity is opened between the upper shell and the lower shell, a rotating shaft extending into the cavity is rotatably connected to the upper shell, and a plurality of stirring blades are fixedly connected to the rotating shaft, and a control device for dividing the cavity into upper and lower stirring areas is arranged between the upper shell and the lower shell, the control device controls the connection between the two stirring areas, and a plurality of stirring blades are evenly distributed in the two stirring areas.
[0007] By adopting the above technical solution, the cavity is divided into two stirring areas by using a control device. When stirring, different raw materials are placed in the two stirring areas respectively, and then the protective shell is rotated. The protective shell drives the stirring blades to rotate, and the raw materials in the two stirring areas are stirred respectively. After the stirring and reaction are completed, the upper and lower stirring areas are connected by the control device to further mix the materials in the two stirring areas.
[0008] The utility model is further configured as follows: the control device includes a second separator covering the cross-section of the cavity and abutting against each other, and two first separators, the first separator rotates along the circumferential direction of the lower shell, the first separator and the second separator are provided with channels connected up and down, and the other areas of the first separator and the second separator on the cross-section of the cavity are covering parts, and the projected area of the covering parts on the first separator and the second separator is larger than the cross-sectional area of the cavity.
[0009] By adopting the above technical solution, utilizing the structure of the first separator and the second separator, the cavity is divided into two upper and lower stirring areas in the cross section of the cavity. When the first separator is rotated, the covering part on the first separator moves away from the channel on the other first separator and the second separator, that is, the covering parts on the first separator and the second separator gradually overlap on the projection surface, thereby completing the connection between the channels on the first separator and the second separator, completing the connection between the upper and lower stirring areas, and vice versa completing the isolation of the two stirring areas.
[0010] The utility model is further configured as follows: a limiting groove connected to the cavity is opened at one end of the upper shell and the lower shell that are close to each other, and the limiting grooves on the upper shell and the lower shell are spliced into an annular track groove, and the first separator and the second separator are both slidably connected in the track groove.
[0011] By adopting the above technical solution, the moving track of the first separator is limited by the track, so as to prevent the first separator and the second separator from falling out of the cavity.
[0012] The utility model is further configured as follows: a limiting groove is penetrated through the side wall of the trajectory groove, the first separator and the second separator side walls separate the limiting groove and the cavity, the second separator is arranged between the two first separators, and the side of the first separator is fixedly connected with an extension rod extending outward from the limiting groove.
[0013] By adopting the above technical solution, the rotation angle of the first separator can be manually controlled by using the extension rod extending from the limiting groove on the first separator, thereby controlling the area of the connection between the channels on the first separator and the second separator, thereby controlling the connection area of the upper and lower stirring regions, thereby controlling the mixing and reaction speed of the materials in the upper and lower stirring regions, and increasing the mixing and reaction effect.
[0014] The utility model is further configured as follows: mutually abutting connecting rings are fixedly connected at mutually adjacent positions of the upper shell and the lower shell side surfaces, and the two connecting rings are connected by bolts.
[0015] By adopting the above technical solution, the upper and lower shells are fixedly connected as a whole by bolt connection, while ensuring the sealing of the cavity.
[0016] The utility model is further configured as follows: a protective shell for supporting the servo motor is fixedly connected to the upper end of the upper shell, and the output shaft of the servo motor is fixedly connected to the rotating shaft.
[0017] By adopting the above technical solution, the servo motor drives the rotating shaft to rotate, and the rotating shaft drives the stirring blades to rotate and stir, and then the servo motor and the upper shell are connected by a protective shell. At the same time, the protective shell protects the servo motor to prevent damage to the servo motor during installation and disassembly.
[0018] The utility model is further configured as follows: the side wall of the second dividing sheet is fixedly connected with a limiting block abutting against the inner wall of the limiting groove.
[0019] By adopting the above technical solution, the rotation of the second separator is limited by the structure in which the limit block of the side wall of the second separator abuts against the inner wall of the limiting groove, preventing the second separator from rotating synchronously when the first separator is rotated, thereby increasing the control effect of the channel connection between the first separator and the second separator.
[0020] The utility model is further configured as follows: the arc of the limiting groove along the circumferential direction of the lower shell is greater than the maximum rotation angle of the first dividing sheet.
[0021] By adopting the above technical solution, the limiting groove can meet the rotation stroke of the first separator, and the communication area of the channels on the first separator and the second separator can be between the maximum and 0, thereby increasing the control effect.
[0022] The utility model is further configured as follows: the lower end of the first upper separation sheet is also fixedly connected with a sealing block abutting against another first separation sheet.
[0023] By adopting the above technical solution, when the second separator covers the area that separates the air into two stirring areas on the cross section of the cavity, the gap between the two first separators is sealed to block the connection between the two stirring areas.
[0024] In summary, the utility model has the following beneficial effects:
[0025] By utilizing the structure of the first separator and the second separator, the cavity is divided into two upper and lower stirring areas in the cross section of the cavity. When the first separator is rotated, the covering part on the first separator leaves the channel on the other first separator and the second separator, that is, the covering parts on the first separator and the second separator gradually overlap on the projection surface, thereby completing the connection of the channels on the first separator and the second separator, completing the connection of the upper and lower stirring areas, and vice versa, completing the isolation of the two stirring areas, and then step by step stirring, mixing and reacting various raw materials, and then mixing and reacting the mixed and reacted materials again, thereby reducing the number of reactors required, and also reducing the process of repeatedly taking out various materials from the reactor, reducing the influence of foreign objects on the reaction process, and increasing product stability.

[0034] The present invention will be described in detail below in conjunction with the accompanying drawings in the embodiments of the present invention.
[0035] Example:
[0036] This kind of stable reactor, such as Figures 1 to 6As shown, it includes an upper shell 11 and a lower shell 12 which are connected as a whole and distributed up and down, and a cavity is opened between the upper shell 11 and the lower shell 12, a rotating shaft 16 extending into the cavity is rotatably connected to the upper shell 11, and a plurality of stirring blades 17 are fixedly connected to the rotating shaft 16, and a control device for dividing the cavity into upper and lower stirring areas is arranged between the upper shell 11 and the lower shell 12, the control device controls the connection between the two stirring areas, and the plurality of stirring blades 17 are evenly distributed in the two stirring areas.
[0037] like Figures 4 to 5 As shown, the control device includes a second separator 19 and two first separators 18 covering the cross-section of the cavity and abutting against each other. The first separator 18 rotates in the circumferential direction of the lower shell 12. The first separator 18 and the second separator 19 are provided with channels connecting up and down, and the other areas of the first separator 18 and the second separator 19 on the cross-section of the cavity are covering parts, and the projected area of the covering parts on the first separator 18 and the second separator 19 is larger than the cross-sectional area of the cavity.
[0038] like Figures 1 to 6 As shown, a limiting groove 22 communicating with the cavity is provided at one end of the upper shell 11 and the lower shell 12 close to each other, and the limiting grooves 22 on the upper shell 11 and the lower shell 12 are combined into an annular track groove, the first separator 18 and the second separator 19 are both slidably connected in the track groove, and the side wall of the track groove is penetrated by the limiting groove 14, and the side walls of the first separator 18 and the second separator 19 separate the limiting groove 14 and the cavity, the second separator 19 is arranged between the two first separators 18, and the side of the first separator 18 is fixedly connected to a protruding rod 21 extending outward from the limiting groove 14, and the upper shell 11 and The sides of the lower shell 12 are fixedly connected with connecting rings 15 that abut against each other at positions close to each other, and the two connecting rings 15 are connected by bolts. The upper end of the upper shell 11 is fixedly connected with a protective shell 13 for supporting the servo motor, and the output shaft of the servo motor is fixedly connected to the rotating shaft 16. The side wall of the second separator 19 is fixedly connected with a limit block 20 that abuts against the inner wall of the limiting groove 14. The arc of the limiting groove 14 along the circumferential direction of the lower shell 12 is greater than the maximum rotation angle of the first separator 18. The lower end of the upper first separator 18 is also fixedly connected with a sealing block 23 that abuts against another first separator 18.
[0039] When the raw materials need to be reacted multiple times, first manually push the limiting groove 14 and rotate the first separator 18, so that the covering parts on the first separator 18 and the second separator 19 cover the channels on the first separator 18 and the second separator 19, and at the same time, the sealing block 23 blocks the gap between the two first separators 18 in the vertical direction, so that two stirring areas are formed in the cavity, and the raw materials of group A and group B are respectively put into the upper and lower stirring areas, and the servo motor is started. The servo motor drives the rotating shaft 16 to rotate, and the rotating shaft 16 drives the stirring blades 17 located in the two stirring areas to rotate, thereby mixing the raw materials in the two stirring areas and reacting them to form group A and group B materials. After the mixing and reaction are completed, the limiting groove 14 is manually toggled to connect the channels on the second separator 19 and the first separator 18, thereby connecting the materials of group A and group B in the upper and lower stirring areas. At this time, the upper and lower stirring blades 17 rotate, and the stirring blades 17 in the upper and lower stirring areas face opposite directions, that is, When the upper stirring blade 17 is stirring, it pushes the upper group A material to move into the lower stirring area. When the lower stirring blade 17 rotates, it pushes the lower group B material to move into the upper stirring area, thereby completing the mixing and reaction of the upper and lower parts. At the same time, the structural setting of the limiting groove 14 having an arc greater than the maximum rotation angle of the first separator 18 is used, so that when the first separator 18 rotates, the channel connecting area on the first separator 18 and the second separator 19 is between the maximum and 0, and the limiting groove 14 is controlled by hand to control the speed of the mixing reaction of the group A material and the group B material, thereby improving the product quality. At the same time, this method is used to make the multiple reaction processes take place in the same volume to prevent the influence of the external environment when taking out the materials, thereby improving the product quality. The connecting ring 15 on the upper shell 11 and the lower shell 12 are connected as a whole by bolt connection. When the cavity needs to be cleaned, the upper shell 11 and the lower shell 12 can be disassembled, wherein the protective shell 13 wraps and protects the servo motor, thereby increasing the service life.

All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
