Description

Technical Field

[0001] This invention relates to the technical field of reactor cleaning, and in particular to a reactor cleaning rake mechanism. Background Technology

[0002] In the production of formic acid, sulfuric acid and sodium formate need to be added to an acidification reactor and stirred to allow them to react. During the reaction, residues can solidify and form burnt residue that adheres to the inner wall of the reactor, affecting the reactor's heat conduction and capacity, and potentially impacting the success of subsequent reactions.

[0003] Therefore, existing technologies such as the enamel-lined flat-bottomed concentration reactor disclosed in utility model patent CN202343189U and the reactor distillation residue treatment device disclosed in utility model patent CN202547284U have emerged, which facilitate the scraping off of residues on the inner wall of the reactor during the stirring process.

[0004] During use, it was found that the existing rake-type cleaning mechanism is inconvenient to scrape off residues with strong adhesion. In addition, the plow head is prone to rolling or jamming during the removal of residues with strong adhesion. Furthermore, the existing rake-type cleaning mechanism is large in size, occupies a lot of space in the reactor, and affects the capacity of the reactor, resulting in poor practicality. Therefore, it is urgent to improve the existing equipment. Summary of the Invention

[0005] To solve the above-mentioned technical problems, the present invention provides a stirring mechanism that extends into the interior of a reaction vessel. During the reaction of sulfuric acid and sodium formate, the stirring mechanism is driven to rotate by a drive mechanism to stir the sulfuric acid and sodium formate. At the same time, the height of the stirring mechanism is adjusted by a height adjustment mechanism to improve the uniformity of stirring of sulfuric acid and sodium formate. The stirring mechanism also scrapes off weakly adhering residues on the inner wall of the reaction vessel. After the sulfuric acid and sodium formate have reacted and been discharged, the equipment continues to operate. An alkaline liquid in the storage chamber is sprayed out by a cleaning mechanism, which reacts with the strongly adhering residues to generate salt and water, thus cleaning the strongly adhering residues. Afterward, a rinsing mechanism rinses the interior of the reaction vessel, thereby improving the cleaning effect and practicality of the equipment.

[0006] The present invention provides a cleaning rake mechanism for a reaction vessel, comprising a drive mechanism; and further comprising a height adjustment mechanism, a stirring mechanism, a cleaning mechanism, a rinsing mechanism, and a storage mechanism, wherein the rinsing mechanism and the storage mechanism are both mounted on the height adjustment mechanism, the stirring mechanism is mounted on the drive mechanism, the cleaning mechanism is mounted on the stirring mechanism, and the drive mechanism is mounted on the reaction vessel.

[0007] The height adjustment mechanism adjusts the height of the stirring mechanism, the drive mechanism provides power to the stirring mechanism, the cleaning mechanism cleans the adhesive residues, the rinsing mechanism rinses the inside of the reactor, and the storage mechanism stores the alkaline liquid.

[0008] The stirring mechanism extends into the interior of the reactor. During the reaction of sulfuric acid and sodium formate, the stirring mechanism is driven to rotate, stirring the sulfuric acid and sodium formate. Simultaneously, the height of the stirring mechanism is adjusted by the height adjustment mechanism to improve the uniformity of stirring. The stirring mechanism also scrapes off weakly adhering residues on the inner wall of the reactor. After the sulfuric acid and sodium formate have reacted and been discharged, the equipment continues to operate. The cleaning mechanism sprays out the alkaline liquid in the storage compartment, causing the alkaline liquid to react with the strongly adhering residues, generating salt and water, thus cleaning the strongly adhering residues. Finally, the rinsing mechanism rinses the interior of the reactor, thereby improving the cleaning effect and practicality of the equipment.

[0009] Preferably, the height adjustment mechanism includes an electric cylinder, a frame, two sets of support pipes, a support plate, two sets of annular scrapers, and two sets of solenoid valves. The electric cylinder is mounted on the reactor. The frame and the two sets of support pipes are also mounted on the electric cylinder. The bottom ends of the two sets of support pipes pass through the frame and connect to the top of the support plate. The bottom ends of the two sets of solenoid valves are respectively connected to the top of the two sets of support pipes. A first chamber is provided inside the support plate, and the interiors of the two sets of support pipes communicate with the interior of the support plate. The two sets of annular scrapers are installed inside the reactor and are respectively fitted onto the two sets of support pipes. The stirring mechanism is mounted on the support plate. The height of the stirring mechanism is adjusted by extending or retracting the electric cylinder. At the same time, the liquid on the surface of the two sets of support pipes is scraped off by the two sets of annular scrapers, so that the stirring mechanism can stir sulfuric acid and sodium formate at different heights and clean the inner wall of the reactor. The alkaline liquid and water are discharged into the stirring mechanism through the two sets of support pipes, thereby improving the practicality of the equipment.

[0010] Preferably, the driving mechanism includes a drive motor, a first gear, a splined shaft, and a second gear. The drive motor is mounted on the reactor, the first gear is mounted on the output shaft of the drive motor, the splined shaft is rotatably mounted on the reactor, the bottom end of the second gear is connected to the top end of the splined shaft, and the side end of the second gear meshes with the side end of the first gear. When the drive motor is turned on, the splined shaft drives the stirring mechanism to rotate through the meshing of the first and second gears, thereby improving the practicality of the equipment.

[0011] Preferably, the stirring mechanism includes a splined bushing, multiple sets of stirring blades, and multiple sets of fixing seats. The splined bushing is fitted onto a splined shaft, and the top end of the splined bushing is rotatably connected to the bottom end of a support plate. A second chamber is provided inside the side wall of the splined bushing, and the second chamber inside the splined bushing is connected to the first chamber inside the support plate. Multiple sets of stirring blades are all installed on the splined bushing, and each set of stirring blades has a channel inside. Multiple sets of fixing seats are respectively installed on multiple sets of stirring blades. The splined bushing is rotated by the splined shaft, causing the multiple sets of stirring blades to stir the sulfuric acid and sodium formate, so that the sulfuric acid and sodium formate react fully. During cleaning, the alkaline liquid or water in the support plate is drained into the splined bushing, and then the channels in the multiple sets of stirring blades drain the alkaline liquid or water into the cleaning mechanism, thereby improving the practicality of the equipment.

[0012] Preferably, the cleaning mechanism includes multiple sets of plowshares, multiple sets of first springs, multiple sets of serrated scrapers, multiple sets of second springs, and a neutralization mechanism. The plowshares and serrated scrapers are slidably mounted on multiple sets of fixed bases. The first springs and second springs are also mounted on the fixed bases. The side ends of the plowshares and serrated scrapers are connected to one end of each of the first and second springs. Pressure sensors are installed between each plowshare and each first spring. The rotation of the multiple sets of stirring blades causes the plowshares to clean the weakly adhered surfaces on the inner wall of the reactor. The process involves scraping away residue. When multiple sets of plowshares encounter residue with strong adhesion, the elasticity of multiple sets of first springs causes the plowshares to retract. The serrated scraper then scrapes scratches and grooves into the residue. After the sulfuric acid and sodium formate have reacted and been discharged, the multiple sets of stirring blades continue to rotate. When the pressure sensor between the plowshare and the first spring is subjected to significant pressure, the neutralization mechanism sprays alkaline liquid onto the surface of the residue and into the grooves of the residue. This causes the alkaline liquid to react with the residue with strong adhesion, generating salt and water, thereby improving the practicality of the equipment.

[0013] Preferably, the neutralization mechanism includes multiple sets of first nozzles, multiple sets of second nozzles, and an alkali delivery pump. The multiple sets of first nozzles and multiple sets of second nozzles are respectively installed on multiple sets of stirring blades. The alkali delivery pump is installed on the frame, and the suction port of the alkali delivery pump is connected to the interior of the storage mechanism. The discharge port of the alkali delivery pump is connected to a set of solenoid valves. The alkali liquid in the storage mechanism is discharged into the support pipe through the alkali delivery pump, and then discharged into the channel of the multiple sets of stirring blades through the cooperation of the support plate and the spline bushing. The alkali liquid is sprayed onto the residue through the multiple sets of first nozzles, so that the alkali liquid reacts with the residue. At the same time, the alkali liquid is sprayed out through the multiple sets of second nozzles, so that the alkali liquid reacts with the residue on the stirring mechanism and the first nozzles, thereby improving the practicality of the equipment.

[0014] Preferably, the storage mechanism includes a constant temperature tank and a one-way valve. The bottom of the constant temperature tank is connected to the top of the frame, and the top of the constant temperature tank is provided with a feed inlet. The inside of the constant temperature tank is provided with a corrosion-resistant layer. The bottom of the one-way valve is connected to the top of the constant temperature tank. The constant temperature tank stores alkaline liquid. When the alkaline liquid delivery pump discharges the alkaline liquid from the constant temperature tank, the one-way valve discharges air into the constant temperature tank, reducing pressure changes inside the constant temperature tank and thus improving the practicality of the equipment.

[0015] Preferably, the rinsing mechanism includes a heating box, a breather valve, and a drain pump. The bottom ends of the heating box and the drain pump are connected to the top of the frame. The top of the heating box is provided with a water inlet, the bottom end of the breather valve is connected to the top of the heating box, the suction outlet of the drain pump is connected to the interior of the heating box, and the discharge outlet of the drain pump is connected to another set of solenoid valves. After the alkaline liquid neutralizes the residue, the water is heated by the heating box. Then, the drain pump is turned on, one set of solenoid valves is closed, and another set of solenoid valves is turned on to discharge hot water into multiple sets of stirring blades. The hot water is sprayed out through multiple sets of first nozzles and multiple sets of second nozzles to rinse the interior of the reactor, thereby improving the practicality of the equipment.

[0016] Preferably, the device also includes multiple sets of third springs and multiple sets of baffles. One end of each set of third springs is installed on a set of first nozzles and a set of second nozzles, and the baffles are installed on the other end of each set of third springs. The elasticity of the multiple sets of third springs causes the baffles to block the nozzles of the first and second nozzles, reducing the clogging of the nozzles by residues. When alkaline liquid or hot water is sprayed from the first and second nozzles, the pressure of the alkaline liquid or hot water pushes the baffles open, allowing the alkaline liquid or hot water to be sprayed out, thereby improving the practicality of the equipment.

[0017] Preferably, the cleaning method includes the following steps:

[0018] S1. The alkaline liquid is stored in a constant temperature tank, and the water is heated in a heating box. The stirring mechanism is inserted into the interior of the reaction vessel. During the reaction of sulfuric acid and sodium formate, the stirring mechanism is driven to rotate by the drive mechanism to stir the sulfuric acid and sodium formate. At the same time, the height of the stirring mechanism is adjusted by the height adjustment mechanism to improve the uniformity of stirring the sulfuric acid and sodium formate.

[0019] S2. During the stirring process, multiple sets of stirring blades rotate, causing multiple sets of plows to scrape off the weakly adhering residues on the inner wall of the reactor. When multiple sets of plows encounter residues with strong adhesion, the elasticity of multiple sets of first springs causes multiple sets of plows to retract, and the serrated scraper scrapes scratches and grooves on the residues with strong adhesion.

[0020] S3. After the sulfuric acid and sodium formate have reacted and been discharged, multiple sets of stirring blades continue to rotate. After the pressure sensor between the plow and the first spring is squeezed by a large force, the alkaline liquid is sprayed onto the surface of the residue and the grooves of the residue through the neutralization mechanism, so that the alkaline liquid reacts with the residue with strong adhesion to generate salt and water. At the same time, the residue is scraped and removed by the plow and the toothed scraper.

[0021] S4. The alkaline liquid is sprayed out through multiple sets of second nozzles, so that the alkaline liquid reacts with the stirring mechanism and the residue on the first nozzle;

[0022] S5. Turn on the drain pump, close one set of solenoid valves, and open another set of solenoid valves to drain hot water into multiple sets of stirring blades. The hot water is then sprayed out through multiple sets of first nozzles and multiple sets of second nozzles to rinse the inside of the reactor.

[0023] S6. Discharge the wastewater from the reactor.

[0024] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0025] 1. By repeatedly scraping the residue and neutralizing it with alkali, the residue is cleaned, improving the cleaning effect and extending the service life of the plow and saw blade.

[0026] 2. The plow head rebounds, causing the serrated scraper to scratch and groove on the residue with strong adhesion, which facilitates the reaction between the alkali solution and the residue and improves the cleaning speed of the residue.

[0027] 3. By adjusting the height of the stirring mechanism, the smaller stirring mechanism can stir sulfuric acid and sodium formate at different heights in the reactor, clean the inner wall of the reactor at different heights, and reduce the space occupied by the stirring mechanism.

[0028] 4. The alkaline solution is sprayed out through multiple sets of second nozzles to clean the residue on the stirring mechanism and the first nozzle. Attached Figure Description

[0051] like Figure 4 , Figure 5 and Figure 6 As shown, the stirring mechanism includes a splined bushing 11, multiple sets of stirring blades 12, and multiple sets of fixing seats 13.

Then, the drive motor 7 is turned on, and the splined shaft 9 rotates the stirring mechanism via the meshing of the first gear 8 and the second gear 10. This causes multiple sets of stirring blades 12 to stir the sulfuric acid and sodium formate. The rotation of the stirring blades 12 also causes multiple sets of plowshares 14 to scrape off weakly adhering residues from the inner wall of the reactor. When the plowshares 14 encounter strongly adhering residues, the elasticity of multiple sets of first springs 15 causes the plowshares 14 to retract. The serrated scraper 16 then scrapes scratches and grooves onto the strongly adhering residues. The reaction of sulfuric acid and sodium formate... After the mixture is discharged, the multiple sets of stirring blades 12 continue to rotate. When the pressure sensor 18 between the plow head 14 and the first spring 15 is squeezed by a large force, the alkaline liquid in the storage mechanism is discharged into the support pipe 3 by the alkaline liquid delivery pump 21.

During stirring, multiple sets of stirring blades 12 rotate, causing multiple sets of plowshares 14 to scrape off weakly adhering residues on the inner wall of the reaction vessel. When the plowshares 14 encounter strongly adhering residues, the elasticity of multiple sets of first springs 15 causes the plowshares 14 to retract, and serrated scrapers 16 scrape scratches and grooves on the strongly adhering residues. After the sulfuric acid and sodium formate have reacted, the residues are cleaned and cleaned. After discharge, the multiple sets of stirring blades 12 continue to rotate. When the pressure sensor 18 between the plow head 14 and the first spring 15 is squeezed by a large force, the alkaline liquid is sprayed onto the surface of the residue and into the grooves of the residue through the neutralization mechanism. The alkaline liquid reacts with the residue with strong adhesion to generate salt and water. At the same time, the residue is scraped and removed by the plow head 14 and the serrated scraper 16. The alkaline liquid is sprayed out through the multiple sets of second nozzles 20, so that the alkaline liquid reacts with the residue on the stirring mechanism and the first nozzle 19. After the alkaline liquid neutralizes the residue, the drain pump 26 is turned on, one set of solenoid valves 6 is turned off, and another set of solenoid valves 6 is turned on to discharge hot water into the multiple sets of stirring blades 12. The hot water is sprayed out through the multiple sets of first nozzles 19 and multiple sets of second nozzles 20 to rinse the inside of the reactor. Then the wastewater in the reactor is discharged.

[0056] The main functions achieved by this invention are: to quickly clean up residues, to reduce the space occupied by the stirring mechanism in the reactor, and to clean up neutralization products;

[0057] 1. Quickly clean up residue: Use a plow to scrape off weakly adhering residue, use a serrated scraper to scrape scratches and grooves on strongly adhering residue, and then spray alkaline liquid onto the residue to neutralize it and remove it.

[0058] 2. Reduce the space occupied by the stirring mechanism inside the reactor: The height of the stirring mechanism can be adjusted by a height adjustment mechanism, so that the smaller stirring mechanism can complete the stirring of sulfuric acid and sodium formate inside the reactor;

[0059] 3. Cleaning the neutralization products: Rinse the inside of the reactor with hot water to wash away the neutralization products.

[0060] All components located inside the reactor are treated with anti-corrosion measures.
