Technical Field
[0001] The invention relates to the technical field of reactors, and in particular to a system for removing residues from the inner wall of a reactor by immersion and stirring. Background Art
[0002] Reactors are containers for physical or chemical reactions. Through structural design and parameter configuration of the container, they can achieve heating, evaporation, cooling and low-speed mixing functions required by the process. They are widely used in petroleum, chemical industry, rubber, pesticides, dyes, medicine, and food to complete processes such as vulcanization, nitration, hydrogenation, hydrocarbonization, polymerization, and condensation.
[0003] Among them, when the reactor is producing and processing some hard materials, after the materials are taken out, the residues after material processing will adhere to the inner wall of the reactor. The materials produced by the reactor in the chemical industry are mostly crystals with hard texture. Therefore, the residues on the inner wall of the reactor are not easy to remove by conventional methods. For example, in patent CN201922155625.6, the spiral cleaning structure is not easy to clean the bottom of the reactor, and the removed residues are easily discharged along the discharge pipe together with the cleaning water, which has a great impact on the subsequent water treatment process. Summary of the invention
[0004] The technical problem to be solved by the present invention is that after the production of the reactor, the residue on the inner wall is relatively hard and difficult to remove. A system for soaking, stirring and removing residues from the inner wall of the reactor is provided, which can effectively remove the residues on the inner wall while stirring and turning the reactor with clean water injected.
[0005] The present invention is achieved through the following technical solutions:
[0006] A system for removing residue from the inner wall of a reactor by immersion stirring, comprising:
[0007] An operating table, on which a kettle body is installed;
[0008] A cleaning mechanism, the cleaning mechanism comprising a stirring shaft and an ultrasonic rod, the stirring shaft is located in the kettle body, and the stirring shaft and the kettle body are coaxially arranged;
[0009] A turning mechanism, the turning mechanism is sleeved and rotatably connected to the outer peripheral wall of the stirring shaft;
[0010] Wherein, the flipping mechanism is connected to a driving component, and the driving component is used to drive the flipping mechanism to rotate or drive the ultrasonic rod to generate ultrasonic waves. The flipping mechanism can slide up and down along the height direction of the stirring shaft, and the flipping mechanism can scrape off the residue on the inner wall of the kettle body when rotating.
[0011] In the above technical scheme, before removing the residue, the kettle body is first soaked in a specific solution to reduce the hardness of the residue, and then the solution is extracted and put into clean water, and the ultrasonic rod generates ultrasonic waves to peel off the residue. At the same time, the driving component controls the rotation of the flipping mechanism, and the rotating mechanism can scrape off the residue on the inner wall of the reactor. After completing the cleaning work, the relevant equipment can be taken out and the water in the kettle body can be discharged.
[0012] In some optional technical solutions, the flipping mechanism includes a rotating ring and a plurality of stirring wings, the driving assembly includes a bracket, a turntable and a power source arranged in the turntable, the turntable is located at the top of the kettle body, the turntable is connected to the bracket, the bracket is clamped and electrically connected to the top surface of the rotating ring, the bracket is retractable, the rotation of the turntable drives the rotating ring to rotate through the bracket, and at the same time, the power source controls the extension or shortening of the bracket to drive the rotating ring to move downward or upward along the height direction of the stirring shaft, and the end of the stirring wing away from the rotating ring contacts the kettle body.
[0013] In the above technical solution, the bracket can control the rotating ring to move up and down along the stirring shaft, and can control the rotating ring to rotate. When the rotating ring rotates, it drives the stirring wing to rotate synchronously, and the residue on the inner wall of the kettle can be effectively scraped off by the stirring wing.
[0014] In some optional technical solutions, a convex column is provided on the inner circumferential wall of the rotating ring, a spiral groove is provided on the outer circumferential wall of the stirring shaft, and the convex column is adapted to be snap-fitted and slidably connected to the spiral groove.
[0015] In the above technical solution, the convex column of the rotating ring is engaged with the spiral groove of the stirring shaft, which can effectively prevent the rotating ring from falling too fast, thereby causing the stirring wings to be unable to be effectively cleaned.
[0016] In some optional technical solutions, the stirring wings are equidistantly arranged around the rotating ring, and the stirring wings include a wing handle and a wing knife. The wing knife is arranged at one end of the wing handle away from the rotating ring, and the wing handle and the wing knife have equal thickness.
[0017] In the above technical solution, the wing handle is used to connect the transmission and can stir the water in the kettle body, and the wing knife is mainly used to remove the residue on the inner wall of the kettle body.
[0018] In some optional technical solutions, the bottom surface of the wing handle is a plane, and a receiving groove is provided at the bottom of the wing handle. A scraper is slidably connected in the receiving groove, and one end of the scraper close to the wing blade is hinged to the receiving groove.
[0019] In the above technical solution, when the rotating ring falls to the bottom of the kettle body, the scraper is flush with the bottom surface of the kettle body, and the scraper can clean the bottom surface of the kettle body during the rotation process.
[0020] In some optional technical solutions, the end surface of the scraper facing the bottom surface of the kettle body is a flat surface or a curved surface.
[0021] In the above technical solution, the reaction kettle has a flat bottom, a conical bottom and a round bottom. Scrapers with different bottom structures can be selected according to the different reaction kettles to be cleaned.
[0022] In some optional technical solutions, two sides of the wing handle along the thickness direction are parallel planes or curved surfaces bent in the same direction.
[0023] In the above technical solution, the curved wing handle has a better rotation effect than the flat wing handle and can generate a vortex faster.
[0024] In some optional technical solutions, a storage groove is provided downward on the top surface of the stirring shaft, a partition tube is provided in the storage groove, an air supply pipe is provided in the partition tube, air holes are provided in the spiral groove and on the outer peripheral wall of the partition tube, a groove is provided on the inner wall of the rotating ring, and a filter plate is provided in the groove along the height direction of the stirring shaft.
[0025] In the above technical solution, the air supply pipe is used to inject gas into the water in the kettle to generate bubbles, which are mixed with the ultrasonic waves emitted by the ultrasonic rod to enhance the efficiency of the ultrasonic waves.
[0026] In some optional technical solutions, a plurality of limit grooves are provided on the outer peripheral wall of the stirring shaft, a baffle is hingedly connected to the middle part of the limit groove through a rotating shaft, a through groove connected to the storage groove is provided in the limit groove, the through groove is located above the rotating shaft, and the distance between the baffle and the bottom of the stirring shaft is greater than the height of the rotating ring.
[0027] In the above technical solution, when the rotating ring moves to the bottom of the stirring shaft, it is away from the baffle, the extrusion force on the baffle disappears and it is fully opened, and the rotating ring continues to rotate at the bottom, which can send the attachments to the top of the water in the kettle through the vortex generated by the rotation. During the process of stopping rotation or rotating, some attachments will fall through the baffle into the storage tank for collection.
[0028] In some optional technical schemes, the baffle is L-shaped, and the baffle includes a first baffle and a second baffle, the first baffle and the second baffle are connected by the rotating shaft, the first baffle is located above the through groove, an end face of the first baffle close to the stirring shaft and an end face of the second baffle away from the stirring shaft are both arc-shaped inclined surfaces, a filter is arranged at the air hole of the separator tube, the two side faces of the baffle along the width direction are first inclined surfaces, and the two side faces of the filter plate along the width direction are also second inclined surfaces, and the inclined directions of the first inclined surface and the second inclined surface are opposite.
[0029] In the above technical solution, when the rotating ring rotates at the bottom, the first baffle can collect the attachments and enter the storage tank. The attachments entering the storage tank will be separated by the filter and will not enter the separation tube in large quantities to affect gas transportation. Moreover, because the separation tube is located in the water and in the stirring shaft, even if some attachments enter, they will be precipitated and will not affect gas transportation.
[0030] Compared with the prior art, the present invention has the following advantages and beneficial effects:
[0031] 1. In the present invention, the bracket and the rotating ring cooperate with each other, rise or fall along the stirring shaft, and the rotating ring can rotate. When the rotating ring falls and rotates, the wing knife can scrape off the soaked attachments. An air delivery pipe is added to the stirring shaft to generate bubbles to the water in the kettle body, and an ultrasonic rod is added to generate vibration. The combination of the two can effectively reduce the hardness of the attachments, so that the attachments are peeled off under the action of the rotating wing knife. When the rotating ring moves to the bottom surface, the inner circumferential wall of the kettle body has also been cleaned, and when the attachments are scraped off the inner wall, the second shield at the bottom of the rotating ring will collect the scraped attachments, so that the efficiency of scraping off the attachments is increased;
[0032] 2. In the present invention, after the rotating ring moves to the bottom surface of the kettle body, it will continue to rotate. A number of rotating wing handles form a turbine-like effect, generating a vortex in the kettle body filled with water, so that the peeled and scraped attachments rise with the vortex. When the rotating ring rotates or stops rotating, part of the attachments fall through the first baffle into the storage tank to complete the collection, which can effectively prevent a large amount of attachments from being discharged with the sewage in the kettle body, resulting in an increase in the cost of water treatment in the later stage;
[0033] 3. In the process of scraping off attachments in one cycle of the rotating ring, the kettle body can be cleaned twice. After one cleaning, the rotating ring is located at the bottom of the kettle body, but because the first baffle is extended and bubbles produced by the air supply pipe in the through groove continue to break on the inner wall of the kettle body, the attachments remaining after the first cleaning of the kettle body can be further vibrated and peeled off. Then the rotating ring rises, which can scrape and clean the inner wall of the kettle body again and collect most of the peeled attachments, thereby enhancing the cleaning efficiency and reducing the cost of subsequent water treatment.

DETAILED DESCRIPTION
[0043] In order to make the purpose, technical scheme and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the embodiments and drawings. The schematic implementation modes and descriptions of the present invention are only used to explain the present invention and are not intended to limit the present invention. It should be noted that the present invention is already in the actual development and use stage.
[0044] Example 1
[0045] like Figures 1 to 6 As shown, this embodiment provides a system for removing residue from the inner wall of a reactor by immersion stirring, comprising:
[0046] An operating table, on which a kettle body 1 is installed;
[0047] The cleaning mechanism comprises a stirring shaft 2 and an ultrasonic rod. The stirring shaft 2 is located in the kettle body 1, and the stirring shaft 2 and the kettle body 1 are coaxially arranged;
[0048] A turning mechanism, which is sleeved and rotatably connected to the outer peripheral wall of the stirring shaft 2;
[0049] Among them, the flipping mechanism is connected to a driving component, which is used to drive the flipping mechanism to rotate or drive the ultrasonic rod to generate ultrasonic waves. The flipping mechanism can slide up and down along the height direction of the stirring shaft 2. When the flipping mechanism rotates, it can scrape off the residue on the inner wall of the kettle body 1.
[0050] like Figure 5 and Figure 6As shown, the flipping mechanism includes a rotating ring 4 and a plurality of stirring wings, and the driving assembly includes a bracket 31, a turntable 3 and a power source arranged in the turntable 3. The turntable 3 is located at the top of the kettle body 1, and the turntable 3 is connected to the bracket 31. The bracket 31 is snap-fitted and electrically connected to the top surface of the rotating ring 4. The bracket 31 is retractable. The rotation of the turntable 3 drives the rotating ring 4 to rotate through the bracket 31. At the same time, the power source controls the bracket 31 to extend or shorten to drive the rotating ring 4 to move downward or upward along the height direction of the stirring shaft 2, and the end of the stirring wing away from the rotating ring 4 contacts the kettle body 1.
[0051] like Figure 1 and Figure 6 As shown, a convex column is arranged on the inner peripheral wall of the rotating ring 4, and a spiral groove 21 is opened on the outer peripheral wall of the stirring shaft 2. The convex column and the spiral groove 21 are adapted to be engaged and slidably connected.
[0052] like Figure 5 As shown, the stirring wings are equidistantly arranged around the rotating ring 4, and the stirring wings include a wing handle 41 and a wing knife 42. The wing knife 42 is arranged at one end of the wing handle 41 away from the rotating ring 4, and the thickness of the wing handle 41 and the wing knife 42 are equal.
[0053] Specifically, after the reactor is used, a large amount of residue will accumulate on the inner wall, which is not easy to be soaked away. Usually, a strong alkaline solution is used to decompose the residue on the inner wall of the reactor (the soaking solvent is a 30% concentration KOH solution) and a high-temperature heating system is used to heat the KOH solution to 80°, so that the residue will not stubbornly adhere to the inner wall. Then the solution in the reactor is pumped out and clean water is injected. The stirring shaft 2 can be extended into the reactor body 1 by starting the operating table. The operating table is used for placing the reactor body 1 and providing a power source, which is not shown in the figure. The operating table is electrically connected to the turntable 3 for providing power to the turntable 3. The turntable 3 drives the rotating ring 4 to slide downward through the bracket 31. The bracket 31 and the rotating ring 4 are electrically connected. Preferably, The rotating ring 4 is divided into a connecting part connected to the bracket 31 at the top and a rotating part for rotation at the bottom. The rotating part is rotatably connected to the connecting part. Therefore, when the bracket 31 controls the connecting part to be energized, the rotating part of the rotating ring 4 will rotate on its own. When the rotating ring 4 rotates, the stirring wing connected to the rotating ring 4 will rotate synchronously. The wing knife 42 of the stirring wing contacts the inner wall of the reactor. As the rotation occurs, the wing knife 42 will scrape off the residue on the inner wall of the reactor, and as the rotating ring 4 gradually moves downward, the wing knife 42 can also completely scrape off the residue on the inner wall of the reactor. When the rotating ring 4 rotates, the convex column can cooperate with the spiral groove 21, similar to the connection method of the screw and nut, to prevent the rotating ring 4 from falling instantly and affecting the cleaning effect.
[0054] like Figure 6As shown, the bottom surface of the wing handle 41 is a plane, and a receiving groove 411 is provided at the bottom of the wing handle 41 . A scraper 412 is slidably connected in the receiving groove 411 , and one end of the scraper 412 close to the wing blade 42 is hinged to the receiving groove 411 .
[0055] Two sides of the wing handle 41 along the thickness direction are parallel planes or curved surfaces bent in the same direction.
[0056] like Figures 3 to 5 As shown, a storage groove is provided downward on the top surface of the stirring shaft 2, a partition tube 22 is provided in the storage groove, an air supply pipe 23 is provided in the partition tube 22, air holes are provided in the spiral groove 21 and on the outer peripheral wall of the partition tube 22, a groove is provided on the inner wall of the rotating ring 4, and a filter plate 43 is provided in the groove along the height direction of the stirring shaft 2.
[0057] Example 2
[0058] like Figures 1 to 4 As shown, a plurality of limit grooves are provided on the outer peripheral wall of the stirring shaft 2, a baffle 24 is hinged in the middle of the limit groove through a rotating shaft, a through groove 25 connected to the storage groove is provided in the limit groove, the through groove 25 is located above the rotating shaft, and the distance between the baffle 24 and the bottom of the stirring shaft 2 is greater than the height of the rotating ring 4.
[0059] like Figures 2 to 4 As shown, the baffle 24 is L-shaped, and the baffle 24 includes a first baffle 241 and a second baffle 242. The first baffle 241 and the second baffle 242 are connected by a rotating shaft. The first baffle 241 is located above the through groove 25. An end surface of the first baffle 241 close to the stirring shaft 2 and an end surface of the second baffle 242 away from the stirring shaft 2 are both arc-shaped inclined surfaces. A filter is provided at the air hole of the separator tube 22. The two side surfaces of the baffle 24 along the width direction are first inclined surfaces, and the two side surfaces of the filter plate 43 along the width direction are also second inclined surfaces. The inclined directions of the first inclined surface and the second inclined surface are opposite.
[0060] Specifically, a storage groove is provided in the stirring shaft 2, and a partition tube 22 is provided in the storage groove. Air holes are provided on the partition tube 22 and the stirring shaft 2. An air supply pipe 23 is provided in the partition tube 22. The air supply pipe 23 is used to transport gas. The gas can be carbon dioxide gas. When the gas enters the kettle body 1 filled with water, bubbles will be generated. An ultrasonic rod is provided in the kettle body 1, which can vibrate the attachments. At the same time, the bubbles will burst, and the ultrasonic wave will produce an excitation effect, which plays a role in assisting the peeling of the attachments. The ultrasonic rod can be set in the partition tube 22 and work synchronously with the rotating ring 4. It should be noted that the ultrasonic rod can also generate ultrasonic waves to vibrate and peel off the attachments in the kettle body 1 before the rotating ring 4 works.
[0061] During the rotation of the rotating ring 4, the bubbles ejected from the air holes on the stirring shaft 2 will be cut, broken and split by the wing handle 41 on the rotating ring 4, becoming a number of small bubbles, which can further peel off the attachments. At the same time, the rotating wing handle 41 can also flip and rotate the bubbles, so that the bubbles are evenly filled in the interior of the kettle body 1. A groove is opened on the rotating ring 4, and a filter plate 43 is arranged in the groove. The filter plate 43 can also split the bubbles.
[0062] A limiting groove is also provided on the stirring shaft 2, and a baffle 24 is hinged at the limiting groove. The baffle 24 is L-shaped and includes a first baffle 241 and a second baffle 242 arranged vertically. A rotating shaft is provided at the connection between the first baffle 241 and the second baffle 242. A through groove 25 located above the rotating shaft is provided on the limiting groove, and the through groove 25 is connected to the storage groove. An end surface of the first baffle 241 close to the stirring shaft 2 and an end surface of the second baffle 242 away from the stirring shaft 2 are both arc-shaped inclined surfaces.
[0063] Movement mode of the baffle 24: When cleaning, first insert the stirring shaft 2 into the kettle body 1, and the stirring shaft 2 is sleeved with a rotating ring 4. When the baffle 24 is in the initial state, the first baffle 241 is located in the limit groove and is arranged parallel to the stirring shaft 2, and the second baffle 242 is located outside the stirring shaft 2 and is arranged perpendicular to the stirring shaft 2. When the rotating ring 4 rotates and falls, the wing knife 42 will scrape off the attachments at the corresponding height and fall. Most of the fallen attachments will fall on the opened second baffle 242. The second baffle 242 is provided with an arc-shaped inclined surface. The attachments falling on the arc-shaped inclined surface will be along the passage on the rotating shaft. The groove 25 falls into the storage groove to complete the collection of the attachments at this position, and the rotating ring 4 continues to fall. The bottom surface of the rotating ring 4 contacts and presses down with the second baffle 242, and the second baffle 242 is retracted downward into the limit groove. At the same time, under the action of the rotating shaft, the first baffle 241 extends along the limit groove, and the above content is repeated. Whenever the rotating ring 4 cleans the inner wall of the kettle body 1, the attachments will fall to the second baffle 242 on the lower layer for collection until the rotating ring 4 rotates to the bottom of the stirring shaft 2. Preferably, the length of the first baffle 241 and the second baffle 242 is close to the radius of the kettle body for optimal.
[0064] When the rotating ring 4 rotates to the bottom of the stirring shaft 2: It should be noted that there should be an appropriate distance between the baffle plate 24 at the bottom layer and the bottom surface of the stirring shaft 2, so that the rotating ring 4 can continue to rotate along the spiral line to scrape off the attachments on the bottom surface and the bottom side wall of the kettle body 1. Preferably, since the rotating ring 4 is divided into a connecting part and a rotating part, a convex column may not be provided, and the rotating part can rotate on its own under the action of the bracket 31; when the rotating ring 4 rotates at the bottom, in addition to scraping off the bottom attachments as described in Example 1, a vortex can also be generated in the kettle body 1 filled with clean water. The rising vortex will drive the attachments that have been scraped off and not collected. At this time, the first baffle plate 241 in the limiting groove is located outside the stirring shaft 2, and the rising attachments rotate with the vortex and pass through the corresponding The gap between the adjacent baffles 24 rises, and the rising attachments pass over the extended first baffle 241. Part of the attachments fall on the first baffle 241, enter the through groove 25 through the arc-shaped inclined surface of the first baffle 241, and fall into the storage groove. Preferably, the driving component can be used to control the rotating ring 4 to stop intermittently to make the vortex disappear, and most of the attachments fall onto the first baffle 241 and are collected through the above content; it should also be noted that the kettle body 1 is filled with clean water. When the rotating ring 4 rotates, the water in the kettle body 1 will rotate, and the surrounding water level will rise, and the extended first baffle 241 or the second baffle 242 can reduce the disturbance of the water flow, thereby avoiding the water at the inlet of the kettle body 1 from overflowing due to the rotation of the rotating ring 4 and causing unnecessary losses.
[0065] When the rotating ring 4 rises, the filter plate 43 and the rotating ring 4 itself will contact the first baffle 241, so that the first baffle 241 is reset and the second baffle 242 is extended. After the rotating ring 4 rises to the initial position, the stirring shaft 2 can be raised through the operating table. Preferably, the bottom surface of the stirring shaft 2 is provided with an openable and closable valve. By opening the valve, the attachments can be collected separately, and the water in the kettle body 1 can be discharged to the next step for water treatment, thereby reducing the amount of attachments in the sewage and reducing the cost of subsequent water treatment.
[0066] A partition tube 22 is provided in the storage groove of the stirring shaft 2, and an air supply pipe 23 is provided in the partition tube 22 for generating bubbles, which are combined with ultrasonic waves to break and clean the attachments. A filter is provided on the partition tube 22 to prevent a large amount of attachments in the storage groove from entering the partition tube 22. It should be noted that even if the attachments become smaller and pass through the filter screen into the partition tube 22 due to the vibration of the bubble breakage, it will not affect the effect of the air supply pipe 23 in generating bubbles; when the first baffle 241 or the second baffle 242 extends out of the limit groove, the attachments will fall on the arc-shaped inclined surface due to the above content, and at this time The bubbles in the air supply pipe 23 will continue to vibrate and crush the materials on the arc-shaped inclined surface through the through groove 25, making the materials smaller and falling into the storage tank through the through groove 25, which is also convenient for subsequent processing; in addition, when the first baffle 241 or the second baffle 242 is extended outward, the originally closed through groove 25 is instantly connected to the water in the kettle body 1, and the cavitation and vibration generated by the air supply pipe 23 and the ultrasonic rod in the separation tube 22 will instantly pass through the through groove 25 to the outside of the stirring shaft 2, which can enhance the crushing effect of the attachments on the baffle 24 or the inner wall of the kettle body 1.
[0067] Finally, as mentioned above, the operation mode of the rotating ring 4 is from top to bottom. After rotating at the bottom of the stirring shaft 2 for a certain period of time, it moves from bottom to top. Preferably, the air hole located on the stirring shaft 2 is a through groove 25. When the rotating ring 4 rotates, the bubbles in the kettle body 1 will be evenly broken up and filled in the kettle body 1. When the rotating ring 4 rotates to the bottom of the stirring shaft 2, the through groove 25 continues to spray bubbles, and the bubbles are broken along the first baffle 241 toward the inner wall of the kettle body 1, which can perform secondary cleaning on the inner wall of the kettle body 1. Finally, the rotating ring 4 rises, completes the collection of attachments, and at the same time, it will scrape the inner wall of the kettle body 1 for a secondary time, further enhancing the cleaning effect, that is, in the entire cycle of the rotating ring 4, it not only collects attachments, but also can perform secondary cleaning on the kettle body 1 at the same time.
[0068] Example 3
[0069] The end surface of the scraper 412 facing the bottom surface of the kettle body 1 is a flat surface or an arc surface.
[0070] The reaction kettle has a flat bottom, a conical bottom and an arc-shaped bottom. When the present invention is used for a kettle body 1 with a flat bottom or a conical bottom, a scraper 412 with a flat bottom end face is used. When the kettle body 1 is flat, the wing handle 41 is flush with the inner bottom surface of the kettle body 1, and the scraper 412 cannot be exposed. The bottom surface of the kettle body 1 can be cleaned by following the rotation of the rotating ring 4. When it is a conical bottom, the scraper 412 falls and can be parallel to the conical bottom after falling, and can also be cleaned. The kettle body 1 with an arc-shaped bottom uses a scraper 412 with an arc-shaped bottom end, and the effect is the same as that of the scraper 412 with a conical bottom.
[0071] The specific implementation methods described above further illustrate the objectives, technical solutions and beneficial effects of the present invention in detail. It should be understood that the above description is only a specific implementation method of the present invention and is not intended to limit the scope of protection of the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
