Description

Technical Field

[0001] The invention relates to the field of reaction kettles, in particular to a reaction kettle. Background Art

[0002] Reactors are widely used in the fields of petroleum, chemical industry, rubber, pesticide, dye, medicine and food. They are pressure vessels used to complete processes such as vulcanization, nitration, hydrogenation, hydrocarbonization, polymerization and condensation.

[0003] A Chinese patent with publication number CN104437313A discloses a reactor, including a reactor shell, a feed port, a discharge port, a stirring shaft and a motor. One end of the stirring shaft extends into the reactor shell, and the other end extends out of the reactor shell and is connected to the motor. A stirring blade is provided at the bottom end of the stirring shaft.

[0004] The stirring area involved in the rotation of the stirring blades is small, and it often takes more time to stir the materials in the reactor evenly, which will lead to increased power loss. Summary of the invention

[0005] In order to reduce the electric energy consumed in stirring the materials in the reactor until they are uniform, the present application provides a reactor.

[0006] A reactor provided in this application adopts the following technical solution:

[0007] A reactor comprises a shell and a motor arranged on the top of the shell, the output shaft of the motor penetrates into the shell and is provided with a rotating disk, the lower surface of the rotating disk is provided with a first stirring assembly, the first stirring assembly comprises a plurality of stirring rods arranged along a direction away from the axis of the rotating disk, the top ends of the stirring rods are hinged to the rotating disk and the hinge shafts are perpendicular to the axis of the rotating disk, and the heights of the bottom ends of the plurality of stirring rods gradually increase along a direction away from the axis of the rotating disk.

[0008] By adopting the above technical solution, the output shaft of the motor drives the first stirring component to rotate through the rotating disk, and the stirring rod stirs the material in the shell. Since there are a large number of stirring rods, the stirring range is larger, and the material can be stirred more quickly until it is uniform, thereby saving electricity.

[0009] Optionally, a plurality of stirring rods are circumferentially staggered in a direction away from the axis of the rotating disk, and a compression spring is provided on the side of the stirring rod facing away from the axis of the rotating disk, and the other end of the compression spring is supported on the lower surface of the rotating disk relative to the stirring rod.

[0010] By adopting the above technical solution, during the stirring process, the stirring rod will cause a small swing rotation due to impacting the solid material. The setting of the compression spring can increase the swing amplitude of the stirring rod, so that the stirring rod can stir the material relative to the radial direction of the rotating disk, which is beneficial to improving the stirring effect of the material.

[0011] Optionally, the bottom end of the stirring rod is covered with a rubber sleeve.

[0012] By adopting the above technical solution, the rubber sleeve protects the inner wall of the shell, reducing the possibility of direct friction between the bottom end of the stirring rod and the inner wall of the shell, causing damage to the inner wall of the shell.

[0013] Optionally, a plurality of the first stirring components are circumferentially arranged around the axis of the rotating disk.

[0014] By adopting the above technical solution, a plurality of first stirring components are provided, thereby increasing the number of stirring components for the material per unit time, which is beneficial to speeding up the speed at which the material is stirred until it is uniform.

[0015] Optionally, multiple groups of second stirring components are arranged in the shell along the direction from top to bottom, and the second stirring components include a mounting plate and a stirring part arranged on the mounting plate. The mounting plate is also provided with multiple pull wires, and the other end of the pull wire relative to the mounting plate is arranged on the stirring rod.

[0016] By adopting the above technical solution, the stirring rod rotates the mounting disk by pulling the wire, so that the stirring part on the mounting disk can rotate synchronously, thereby stirring the material near the vertical center line of the shell, which is beneficial to improving the comprehensiveness of the stirring of the material in the shell.

[0017] Optionally, the stirring part includes a plurality of first stirring blades and a plurality of second stirring blades, the first stirring blades being arranged to be inclined downward relative to the circumferential rotation direction of the mounting plate, and the second stirring blades being arranged to be inclined downward away from the circumferential rotation direction of the mounting plate, and the plurality of first stirring blades and the plurality of second stirring blades are alternately arranged circumferentially around the axis of the mounting plate.

[0018] By adopting the above technical solution, when the first stirring blade rotates, the material it acts on moves upward; when the second stirring blade rotates, the material it acts on moves downward. In this way, the first stirring blade and the second stirring blade cooperate so that the material can move up and down when being stirred, thereby further improving the stirring effect on the material.

[0019] Optionally, the length directions of the first stirring blade and the second stirring blade are horizontally arranged and point to the axis of the corresponding mounting plate, and the lengths of the plurality of groups of the second stirring components corresponding to the first stirring blade and the second stirring blade gradually increase from top to bottom.

[0020] The adoption of the above technical solution is conducive to improving the comprehensiveness of stirring of materials in the shell.

[0021] Optionally, the mounting plate is arranged in a cone shape with the top of the cone facing upward.

[0022] By adopting the above technical solution, the possibility of a large amount of material remaining on the mounting plate when the material is discharged from the shell is reduced.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] 1. The output shaft of the motor drives the first stirring component to rotate through the rotating disk, and the stirring rod stirs the material in the shell. Since there are more stirring rods, the stirring range is larger, and the material can be stirred more quickly to be uniform, thereby saving electric energy;

[0025] 2. During the stirring process, the stirring rod will swing slightly due to impacting the solid material. The setting of the compression spring can increase the swing amplitude of the stirring rod, so that the stirring rod can stir the material relative to the radial direction of the rotating disk, which is beneficial to improve the stirring effect of the material;

[0026] 3. The stirring rod pulls the mounting plate to rotate through the pull wire, so that the stirring part on the mounting plate can rotate synchronously, thereby stirring the material near the vertical center line of the shell, which is beneficial to improve the comprehensiveness of the stirring of the material in the shell.

[0031] The following is combined with Figure 1-3 This application is described in further detail.

[0032] The embodiment of the present application discloses a reaction kettle.

[0033] Reference Figure 1 The reactor comprises a shell 1 with a hollow interior, a feed port 7 arranged at the top of the shell 1, and a discharge port (not shown in the figure) arranged at the bottom of the shell 1.

[0034] Reference Figure 1 and Figure 2 A motor 2 electrically connected to the control system is bolted to the top of the shell 1. The output shaft of the motor 2 penetrates into the shell 1 and is bolted to a horizontally arranged rotating disk 3. The rotating disk 3 is coaxially arranged with the shell 1 and is close to the top of the shell 1.

[0035] A plurality of first stirring components 4 are provided on the lower surface of the rotating disk 3, and the plurality of first stirring components 4 are evenly arranged around the axis of the rotating disk 3. The cooperation of the plurality of first stirring components 4 can increase the number of stirring times of the material in the housing 1 per unit time.

[0036] Reference Figure 1 and Figure 2 The first stirring assembly 4 includes a plurality of stirring rods 41 arranged along a direction away from the axis of the rotating disk 3. The top ends of the stirring rods 41 are hinged to the rotating disk 3 and the hinge shafts are perpendicular to the axis of the rotating disk 3. The heights of the bottom ends of the plurality of stirring rods 41 gradually increase along a direction away from the axis of the rotating disk 3.

[0037] Reference Figure 1 and Figure 2 , the worker starts the motor 2, the output shaft of the motor 2 drives the rotating disk 3 to rotate, and the rotating disk 3 drives the stirring rod 41 to rotate synchronously, so that the stirring rod 41 can stir the material in the shell 1. Since the number of stirring rods 41 is large, the stirring range of the material is large, so the material can be stirred more quickly to be uniform, thereby reducing the loss of electric energy.

[0038] Under the action of centrifugal force, the stirring rod 41 rotates away from the axis of the rotating disk 3. According to the different speeds of the output shaft of the motor 2, the worker can adjust the stirring area of ​​each stirring rod 41, thereby improving the stirring effect and comprehensiveness of the material.

[0039] Reference Figure 1 and Figure 2 The maximum speed of the motor 2 is set by the control system. When the speed of the motor 2 is at the maximum, the bottom end of each stirring rod 41 is just in close contact with the vertical inner wall of the shell 1.

[0040] The bottom end of the stirring rod 41 is sleeved and bonded with a rubber sleeve 5, which is made of rubber and can protect the inner wall of the shell 1, thereby reducing the possibility of direct friction between the bottom end of the stirring rod 41 and the inner wall of the shell 1, causing damage to the inner wall of the shell 1.

[0041] Reference Figure 1 and Figure 2 A plurality of stirring rods 41 in the same group are circumferentially staggered in a direction away from the axis of the rotating disk 3 , and a compression spring 42 is provided on the side of the stirring rod 41 facing away from the axis of the rotating disk 3 , and the other end of the compression spring 42 is supported on the lower surface of the rotating disk 3 relative to the stirring rod 41 .

[0042] Since the material may be solid, when the stirring rod 41 stirs the solid material, the stirring rod 41 will slightly swing. The setting of the compression spring 42 can increase the swing amplitude of the stirring rod 41, so that the stirring rod 41 can stir the material relative to the radial direction of the rotating disk 3.

[0043] Reference Figure 1 and Figure 3 A plurality of second stirring components 6 are arranged in the shell 1 along the direction from top to bottom. The second stirring components 6 include a mounting disk 61 and a stirring portion arranged on the mounting disk 61. A plurality of pull wires 62 are also tied to the mounting disk 61. One pull wire 62 corresponds to one first stirring component 4. The other end of the pull wire 62 relative to the mounting disk 61 is tied to the stirring rod 41 corresponding to the first stirring component 4 and closest to the axis of the rotating disk 3.

[0044] Reference Figure 1 and Figure 3 When the stirring rod 41 rotates, the mounting plate 61 can be driven to rotate through the pull wire 62, and the mounting plate 61 drives the stirring part to stir the center position of the inner cavity of the shell 1. In this way, the cooperation between the first stirring component 4 and the second stirring component 6 is beneficial to improve the comprehensiveness of the stirring of the material in the shell 1.

[0045] Reference Figure 1 and Figure 3 Since the pull wire 62 is tied to the stirring rod 41 and the stirring rod 41 will rotate, the worker can adjust the stirring height of each second stirring component 6 according to the rotation speed of the output shaft of the motor 2.

[0046] Reference Figure 1 and Figure 3 The stirring part includes multiple first stirring blades 631 and multiple second stirring blades 632. The first stirring blades 631 are arranged to be tilted downward relative to the circumferential rotation direction of the mounting plate 61, and the second stirring blades 632 are arranged to be tilted downward away from the circumferential rotation direction of the mounting plate 61. The multiple first stirring blades 631 and the multiple second stirring blades 632 are alternately arranged circumferentially around the axis of the mounting plate 61.

[0047] Reference Figure 1 and Figure 3 The mounting plate 61 can drive the first stirring blade 631 and the second stirring blade 632 to rotate, thereby achieving stirring of the material.

[0048] When the first stirring blade 631 rotates, the material it acts on moves upward; when the second stirring blade 632 rotates, the material it acts on moves downward. In this way, the first stirring blade 631 and the second stirring blade 632 cooperate to allow the material to move up and down when being stirred, thereby further improving the stirring effect on the material.

[0049] Reference Figure 1 and Figure 3 The length directions of the first stirring blade 631 and the second stirring blade 632 are horizontally arranged and point to the axis of the corresponding mounting plate 61. The lengths of the first stirring blades 631 and the second stirring blades 632 of the plurality of second stirring components 6 gradually increase from top to bottom, which is beneficial to improve the comprehensiveness of the stirring of the material in the shell 1.

[0050] Reference Figure 1 and Figure 3 The mounting plate 61 is arranged in a conical shape with the top of the cone facing upward, which reduces the possibility of a large amount of material remaining on the mounting plate 61 when the material is discharged from the housing 1.

[0051] The implementation principle of a reactor in an embodiment of the present application is: a worker starts the motor 2, the output shaft of the motor 2 drives the rotating disk 3 to rotate, and the rotating disk 3 drives multiple stirring rods 41 of the first stirring component 4 to rotate in the shell 1, thereby stirring the material in the shell 1. Since there are a large number of stirring rods 41, the stirring area of ​​the material is larger, which can save the electric energy consumed in stirring the material to be uniform.

[0052] Under the action of centrifugal force, the bottom end of the stirring rod 41 rotates toward the inner wall of the shell 1 , and the worker can adjust the rotation speed of the output shaft of the motor 2 to adjust the stirring area of ​​the first stirring component 4 .

[0053] The stirring rod 41 can also drive the mounting plate 61 to rotate through the pull wire 62, and the mounting plate 61 drives the first stirring blade 631 and the second stirring blade 632 to stir the material near the vertical center line of the shell 1. When the worker adjusts the speed of the output shaft of the motor 2, the stirring height of each second stirring assembly 6 can also be adjusted.

[0054] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
