Description

Technical Field

[0001] This application relates to the field of reactor technology, and in particular to a multi-layer stirring device for a reactor. Background Technology

[0002] A reaction vessel is a commonly used reaction equipment in chemical plants. It mainly uses an electric motor to drive a stirring rod to stir the reactants and make them react fully to obtain the desired substances.

[0003] Patent CN206121747U discloses a reaction vessel. In use, three scraper agitators are installed on a vertical stirring rod, arranged along the length of the stirring rod. After the worker puts materials into the reaction vessel, the three scraper agitators can stir and mix the materials in their respective layers, thus achieving a multi-layer stirring effect. A cooling layer is installed inside the reaction vessel, and two control valves can be opened to inject cold water into the cooling layer, thereby rapidly cooling the reaction vessel. The applicant argues that during the process of fixing the cooling layer to the inner wall of the reaction vessel, scale easily adheres to the inner wall of the cooling layer. Scale affects the cooling effect of the cooling layer on the inside of the reaction vessel. Furthermore, if cleaning the cooling layer is required, the worker must first disassemble the reaction vessel and then remove the cooling layer for cleaning, which is quite troublesome. Utility Model Content

[0004] The purpose of this application is to address the aforementioned problems existing in the prior art by proposing a multi-layer stirring device for a reaction vessel.

[0005] This application can be achieved through the following technical solution: a multi-layer stirring device for a reaction vessel, including a rotating ring, several stirring rods are installed on the rotating ring, and several stirring blades are provided on the stirring rods along their own length direction. The rotating ring is driven to rotate by a driving assembly. A cooling element is provided through the rotating ring. The cooling element can extend into the interior of the reaction vessel. The cooling element has a water inlet and a water outlet. Water that can cool the interior of the reaction vessel is introduced into the cooling element. The cooling element rests on the end face of the rotating ring.

[0006] In the above technical solution, the drive component drives the rotating ring to rotate, which in turn drives the stirring blades on the stirring rod to rotate, thereby stirring the materials in the reactor. When it is necessary to cool the inside of the reactor, cold water is poured into the cooling element through the water inlet, and the cooling element is placed on the end face of the rotating ring. The cold water can cool the inside of the reactor. The water inlet and outlet are set to facilitate workers to replace the water in the cooling element. If scale accumulates in the cooling element, it can be removed without disassembling the reactor because the cooling element is placed on the end face of the rotating ring. After removing the cooling element, the workers can directly discard it, which is quite convenient.

[0007] Furthermore, the drive assembly includes a fixed sprocket, a ring sprocket coaxially fixed on the rotating ring, a chain meshing with both the ring sprocket and the fixed sprocket, and a motor for driving the fixed sprocket to rotate.

[0008] In the above technical solution, the operator can install a fixed sprocket on a frame, then place the reactor on the frame, and the motor drives the fixed sprocket to rotate. The rotation of the fixed sprocket can drive the stirring rod to rotate through the chain and ring sprocket to stir the material inside the reactor.

[0009] Furthermore, the cooling component includes a fixed cylinder with an upper opening, and a cooling hose wound around the outer wall of the fixed cylinder. The cooling hose has the water inlet and the water outlet. The cooling hose rests on the end face of the rotating ring, and water is introduced into the cooling hose.

[0010] In the above technical solution, when it is necessary to cool the inside of the reactor, the tap water pipe can be connected to the inlet of the cooling hose through a pipe connector, and then the outlet of the cooling hose can be connected to a drain pipe through another pipe connector. The cooling hose can then be continuously replaced with new cold water, which will have a better cooling effect on the inside of the reactor. When the temperature of the tap water is not low enough, workers can put ice blocks into the fixed cylinder to cool the water in the cooling hose.

[0011] Furthermore, the cooling hose is secured to the fixing cylinder with a tear-off adhesive.

[0012] In the above technical solution, when scale accumulates inside the cooling hose, the worker can directly pull the cooling hose to detach it from the fixing cylinder, and then fix a new cooling hose to the fixing cylinder with tear-off adhesive.

[0013] Furthermore, the stirring blade has scale lines along its length.

[0014] In the above technical solution, the operator can use the scale lines on the stirring blade to compare with the reaction vessels of different inner diameters, thereby cutting the stirring blade so that the length of the stirring blade matches the inner diameter of the reaction vessel.

[0015] Furthermore, the stirring blade includes a fixed block and a blade, the fixed block is mounted on the stirring rod, and the fixed block and the blade are connected by bolts.

[0016] In the above technical solution, by connecting the fixed block and the blade with bolts, the included angle between the blade and the stirring rod can be adjusted, so that the position of the blade can be adapted to reactors with different inner diameters.

[0017] Furthermore, it also includes a scraping and stirring blade that can contact the inner bottom surface of the reactor. The scraping and stirring blade has a groove for the end of the stirring rod that is away from the rotating ring to be inserted.

[0018] In the above technical solution, the stirring rod is embedded in the groove, and the position of the scraping stirring blade can be fixed relative to the stirring rod. The rotation of the stirring rod can drive the scraping stirring blade to rotate, and the scraping stirring blade can contact the inner bottom surface of the reactor, thereby making the materials in the reactor more fully mixed.

[0019] Furthermore, the scraping and stirring blades are fixed to the stirring rod by fixing screws.

[0020] In the above technical solution, the scraping and stirring blade is fixed to the stirring rod by fixing screws, which makes the scraping and stirring blade more stable.

[0021] Furthermore, it also includes a cap that can seal one axial end of the rotating ring.

[0022] In the above technical solution, during the stirring process of the stirring rod and stirring blades, the operator can use a cover to seal the rotating ring to prevent impurities from entering the reactor and contaminating the material.

[0023] In summary, this application has the following technical advantages: the drive assembly drives the rotating ring to rotate, and the rotation of the rotating ring can drive the stirring blades on the stirring rod to rotate, thereby stirring the materials in the reactor. When it is necessary to cool the inside of the reactor, cold water is poured into the cooling component through the water inlet, and the cooling component is placed on the end face of the rotating ring. The cold water can cool the inside of the reactor. It is convenient for workers to replace the water in the cooling component. If scale accumulates in the cooling component, since the cooling component is placed on the end face of the rotating ring, it can be removed without disassembling the reactor. After removing the cooling component, the workers can directly discard it, which is quite convenient. Attached Figure Description

Detailed Implementation

[0032] Example 1:

[0033] Reference Figure 1 , 2 and Figure 3 One embodiment of this application provides a multi-layer stirring device for a reactor, including a rotating ring 1. During installation, the rotating ring 1 is tightly fitted with the inner ring of a bearing, and the outer ring of the bearing is tightly fitted with the inner circumference of the feed inlet of the reactor 6. Three stirring rods 2 are installed on the lower end face of the rotating ring 1. The three stirring rods 2 are all vertically arranged, and each stirring rod 2 has the same structure. Each stirring rod 2 is provided with three stirring blades 3. The stirring blades 3 can contact the inner wall of the reactor 6 to stir the material in the reactor 6. The rotating ring 1 is driven to rotate around its own axis by a drive assembly 4. The drive assembly 4 includes a ring sprocket 42 coaxially fixed to the outer wall of the rotating ring 1, a fixed sprocket 41 rotatably mounted on a frame, a chain 43 meshing with both the ring sprocket 42 and the fixed sprocket 41, and a motor 44 for driving the fixed sprocket 41 to rotate. When in use, the reactor 6 is placed on the frame, and the motor 44 is also fixed to the frame. The motor 44 can drive the rotating ring 1 to rotate through the fixed sprocket 41 and the ring sprocket 42. The rotation of the rotating ring 1 can drive the stirring blade 3 to rotate through the stirring rod 2, thus stirring the material in the reactor 6. The stirring blade 3 is provided with scale lines 33 along its own length. By providing scale lines 33, the operator can compare the stirring blade 3 with the inner diameter of the reactor 6 of different inner diameters, and then cut the stirring blade 3 so that its length can be adapted to the inner diameter of the reactor 6.

[0034] Reference Figure 3 The bottom of the three stirring rods 2 is equipped with the same scraping stirring blade 7. The top of the scraping stirring blade 7 is provided with three grooves 71. The three grooves 71 are used one-to-one for the three stirring rods 2 to be inserted. The scraping stirring blade 7 is also fixed to the stirring rod 2 by fixing screws 8. The scraping stirring blade 7 can contact the bottom surface of the inside of the reactor 6, so as to mix the materials in the reactor 6 more thoroughly.

[0035] Reference Figure 4After the material reaction in reactor 6 is completed, the internal temperature of reactor 6 is usually high, so it is necessary to cool down the inside of reactor 6. A cooling element 5 is placed on the upper surface of the rotating ring 1. The cooling element 5 includes a fixed cylinder 51 with an upper opening. The opening of the fixed cylinder 51 is funnel-shaped. The length of the fixed cylinder 51 is approximately the length of the stirring rod 2, and the depth inside the fixed cylinder 51 is approximately its own length. The fixed cylinder 51 extends into the inside of reactor 6. A cooling hose 52 is spirally wound around the outer wall of the fixed cylinder 51 along its length. The cooling hose 52 is fixed to the fixed cylinder 51 with a peelable adhesive, which can be nano-residue-free double-sided tape. The inlet 521 and outlet 522 of the cooling hose 52 are both close to the opening of the fixed cylinder 51. Since the opening of the fixed cylinder 51 is funnel-shaped, the cooling hose 52 can rest on the upper end face of the rotating ring 1 and abut against the outer wall of the funnel-shaped opening of the fixed cylinder 51 under the gravity of the fixed cylinder 51. The inlet 521 can be connected to a water pipe connected to a tap water pipe through a pipe connector, so that the cooling hose 52 is filled with cold water. The cooled water can be discharged from the cooling hose 52 through the outlet 522. The tap water can cool the inside of the reactor 6 through the cooling hose 52. The fixed cylinder 51 has an opening, so workers can put ice cubes inside the fixed cylinder 51 to keep the water in the cooling hose 52 at a low temperature.

[0036] Reference Figure 5 A cover 9 is installed on the rotating ring 1. The cover 9 can seal the axial end of the rotating ring 1 away from the scraping and stirring blade 7, thereby preventing impurities from entering the reactor 6 when the reactor 6 is stirring the material.

[0037] The working principle of this embodiment is as follows: The motor 44 drives the fixed sprocket 41 to rotate. The rotation of the fixed sprocket 41 drives the stirring blade 3 to rotate through the ring sprocket 42, thereby stirring the material inside the reactor 6. When the rotating ring 1 rotates, the operator can remove the cooling component 5 from the rotating ring 1 and insert the cover 9 into the inner ring of the rotating ring 1 to seal the axial end of the rotating ring 1 away from the scraping stirring blade 7. When the rotating ring 1 stops rotating, the operator can remove the cover 9 from the rotating ring 1, place the fixed cylinder 51 at the rotating ring 1 so that the cooling hose 52 abuts against the upper end face of the rotating ring 1, and then use a pipe connector to connect the cooling hose 52 to the water pipe. Ice cubes are placed inside the fixed cylinder 51, and cold water can then be used to cool the inside of the reactor 6 through the cooling hose 52.

[0038] Example 2:

[0039] Reference Figure 6The structure and principle of this embodiment are basically the same as those of embodiment one. The difference is that the stirring blade 3 includes a fixing block 31 and a blade 32. The fixing block 31 is fixed on the stirring rod 2. Both the fixing block 31 and the blade 32 have a through hole. The two through holes are used to insert a bolt. The bolt is threaded with a nut so that the angle of the blade 32 relative to the stirring rod 2 can be adjusted so that the position of the blade 32 can be adapted to the reaction vessel 6 with different inner diameters.

[0040] The working principle of this embodiment is as follows: the operator can rotate the blade 32 according to the inner diameter of the reactor 6, and then fix the blade 32 to the fixing block 31 with bolts so that the tilt angle of the blade 32 relative to the stirring rod 2 is adapted to the inner diameter of the reactor 6.

[0041] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
