Description

Technical Field

[0001] The invention belongs to the technical field of fluoride production, in particular to an alkali washing kettle for processing organic fluorides. Background Art

[0002] Fluorides refer to organic or inorganic compounds containing negatively charged fluorine. Similar to other halogens, fluorine forms mononegative anions and can form binary compounds with all elements except He, Ne, and Ar. Fluorides range from the deadly toxin sarin to the pharmaceutical drug efavirenz, from insoluble calcium fluoride to the highly reactive sulfur tetrafluoride. During the production of fluoride intermediates, alkaline washing kettles are generally required to wash the finished product to remove impurities.

[0003] When washing products in an existing alkali washing kettle, alkali solution is generally added into the alkali washing kettle through a spray pipe provided on the top of the kettle body, and then the alkali solution and the product are stirred and mixed by a stirring paddle. However, this adding method easily leads to insufficient contact between the materials at the bottom of the kettle body and the alkali solution when there is a large amount of materials in the alkali washing kettle, resulting in poor alkali washing effect and failing to meet the use requirements.

[0004] To this end, we have filed a patent application with application number 2020223933470, with the subject name of "Alkali Washing Kettle for Organic Fluoride Production". By setting up a circulating stirring mechanism, the material is fully in contact with the alkali solution, thereby improving the alkali washing effect. At the same time, the filter net is used to filter the raw materials and the residue in the alkali solution, thereby filtering out the residue.

[0005] However, during subsequent use, it was found that when the filter screen filters residue for a long time, the residue will gradually accumulate on the filter screen. As there is too much residue on the filter screen, the filter screen will be blocked, thereby weakening the filtering effect. Summary of the Invention

[0042] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0043] like Figures 1 to 13 As shown, the alkali washing kettle for organic fluoride processing of the present invention comprises a reactor 1; a circulating stirring mechanism and a shock absorbing mechanism are installed in the reactor 1;

[0044] The bottom of the reactor 1 is fixedly connected to a cylinder 11, and the cylinder 11 extends into the reactor 1; the top of the cylinder 11 is closed and the bottom is open; a partition 12 is fixedly connected to the middle of the cylinder 11; and a sealing plate 13 is fixedly connected to the bottom of the cylinder 11 by bolts;

[0045] It also includes a filtering mechanism; the filtering mechanism includes two filtering components, and the two filtering components are mirror images of each other; the filtering component includes a first semicircular ring 2 and a second semicircular ring 21, and the diameter of the first semicircular ring 2 is smaller than the diameter of the second semicircular ring 21;

[0046] The first semicircular ring 2 is fixedly connected to the outer surface of the cylinder 11; the second semicircular ring 21 is fixedly connected to the inner surface of the reactor 1; the inner walls of the first semicircular ring 2 and the second semicircular ring 21 are both provided with a semicircular groove 22, and the cross section of the semicircular groove 22 is T-shaped;

[0047] The first semicircular ring 2 has first guide plates 23 fixedly connected to both end surfaces, and the bottoms of the two first guide plates 23 are bent toward the cylinder 11. The second semicircular ring 21 has second guide plates 24 fixedly connected to both end surfaces, and the bottoms of the two second guide plates 24 are bent toward the cylinder 11.

[0048] A guide groove 25 is formed on the surface of the first guide plate 23 and the second guide plate 24 on the opposite side, and the cross section of the guide groove 25 is T-shaped; the guide groove 25 is connected to the semicircular groove 22; a long groove 14 is formed on the inner wall of the cylinder 11 near the first guide plate 23 and the second guide plate 24 on both sides;

[0049] A filter screen 3 is provided between the first semicircular ring 2, the first guide plate 23 and the second semicircular ring 21, the second guide plate 24, and the filter screen 3 passes through the two long slots 14 on the cylinder 11 and is connected end to end;

[0050] Slide bars 31 are fixedly connected to both sides of the filter screen 3. The slide bars 31 are arranged around the filter screen 3 and connected end to end. The cross section of the slide bar 31 is T-shaped. The slide bar 31 slides in the semicircular groove 22 and the guide groove 25 and follows the filter screen 3 through the two long grooves 14 on the cylinder 11.

[0051] A power assembly is installed on the left side of the cylinder 11, and the power assembly is used to drive the filter 3 to circulate; a cleaning assembly is installed in the cylinder 11, and the cleaning assembly is used to clean the filter 3 passing through;

[0052] Specifically, during alkali washing, the staff adds the raw materials and alkali solution into the reactor 1, and then stirs the raw materials and alkali solution through the stirring mechanism. The mixed liquid of the raw materials and alkali solution passes through the filter 3, thereby filtering the residue in the mixture through the filter 3;

[0053] During the filtering process of the filter 3, the filter 3 is driven to rotate cyclically by the power assembly, and the power assembly drives the two filter screens 3 on the two filter assemblies to move from the first guide plate 23 and the second guide plate 24 to the first semicircular ring 2 and the second semicircular ring 21. At this time, the two filter screens 3 will rotate cyclically in the first semicircular ring 2, the second semicircular ring 21, the first guide plate 23, the second guide plate 24 and through the two long slots 14 in the two filter assemblies. At the same time, the slide bars 31 on the two filter screens 3 will rotate cyclically in the first semicircular ring 2, the second semicircular ring 21, the first guide plate 23, the second guide plate 24 and the semicircular groove 22 and the guide groove 25 on the second guide plate 24;

[0054] When the filter screen 3 is transferred from the first semicircular ring 2 and the second semicircular ring 21 to the position of the first guide plate 23 and the second guide plate 24, the residue on the filter screen 3 is transferred along with the filter screen 3 to the two filter screens 3 between the two first guide plates 23 and the second guide plates 24. Subsequently, the slide bar 31 on the filter screen 3 is guided by the first guide plate 23 and the second guide plate 24, passes through one of the long slots 14 and rotates into the cylinder 11. Then, the filter screen 3 is rotated out through the other long slot 14. When the filter screen 3 passes through the cylinder 11, the cleaning component in the cylinder 11 collects the residue on the filter screen 3, thereby reducing the amount of residue on the filter screen 3.

[0055] In the above process, by driving the filter screen 3 to rotate in a circular motion, the filter screen 3 between the first semicircular ring 2 and the second semicircular ring 21 can be continuously replaced. At the same time, in the process of replacing the filter screen 3, the residue can be taken away and transferred between the two filter screens 3. Then, the residue on the two filter screens 3 is collected by the cleaning component, thereby avoiding the accumulation of residue on the filter screen 3 between the first semicircular ring 2 and the second semicircular ring 21, causing the residue to block the filter screen 3, resulting in the deterioration of the permeability of the filter screen 3 itself, thereby reducing the filtering effect of the filter screen 3 itself.

[0056] In a specific implementation process, the power assembly includes two first motors 4, and the first motors 4 are installed in the cylinder 11 and located above the partition 12; the two first motors 4 are fixedly connected to a drive roller 41, and the other side of the drive roller 41 extends into the inner wall of the reactor 1 and is rotatably connected to the reactor 1; the two filter screens 3 are located between the two drive rollers 41; the two drive rollers 41 are fixedly connected to a rubber layer 42, and the two rubber layers 42 are in contact with the filter screen 3;

[0057] Specifically, when the power assembly drives the filter 3 to rotate in a circular motion, the two first motors 4 rotate first, and the rotation directions are opposite, thereby driving the two driving rollers 41 to rotate. At the same time, the driving rollers 41 drive the two rubber layers 42 to rotate. During the rotation of the two rubber layers 42, the two filter screens 3 located between the two rubber layers 42 can be pushed to rotate upward, thereby causing the filter screen 3 to rotate in a circular motion.

[0058] In a specific implementation process, the cleaning assembly includes two second motors 5; the upper surface of the partition 12 is fixedly connected to the two second motors 5; below the partition 12, two cleaning cylinders 51 are rotatably connected in the cylinder 11, and the bottom of the cleaning cylinder 51 is in contact with the sealing plate 13; the two cleaning cylinders 51 are fixedly connected to the opposite second motors 5;

[0059] The outer surface of the two cleaning cylinders 51 is fixed with a scraper 52, and the height of the scraper 52 is the same as the width of the filter 3; each scraper 52 is provided with a feed groove 53 on the inner wall of the cleaning cylinder 51 on the side close to the cleaning cylinder 51;

[0060] Specifically, when the cleaning component collects the residue on the filter 3, the two filter screens 3 pass through the front and rear sides of the two cleaning cylinders 51 respectively. At the same time, since the length of the scraper 52 is the same as the width of the filter screen 3, the slide bars 31 on both sides of the filter screen 3 will pass through the upper and lower sides of the scraper 52 on the cleaning cylinder 51. At this time, the scraper 52 contacts the passing filter screen 3. In the process of the filter screen 3 passing through the cleaning cylinder 51, the two second motors 5 rotate and the rotation directions are opposite. At the same time, the second motor 5 will drive the two cleaning cylinders 51 to rotate, and the cleaning cylinder 51 will drive the scraper 52 to rotate. In the process of the rotation of the scraper 52, the residue on the two passing filter screens 3 can be scraped off. The scraped residue will enter the interior of the cleaning cylinder 51 for collection under the guidance of the scraper 52 and the feed trough 53.

[0061] In the specific implementation process, two long rods 54 are fixedly connected to the upper surface of the sealing plate 13, and the long rods 54 are extended into the opposite cleaning cylinders 51; the tops of the two long rods 54 are fixedly connected to scrapers 55, and the scrapers 55 are in contact with the tops of the cleaning cylinders 51;

[0062] Guide rods 56 are provided on the left and right sides of the scraper 55 and on the lower surface of the scraper 55;

[0063] The guide rod 56 is rotatably connected to the scraper 55; a runner 57 is fixedly connected to the guide rod 56, and the top of the runner 57 is in contact with the scraper 55, and the runner 57 is inscribed in the inner circle of the cleaning cylinder 51; an auger blade 58 is fixedly connected to the guide rod 56 below the runner 57;

[0064] Specifically, when the reactor 1 is finished working and the mixed liquid is discharged, the staff uses a wrench to remove the bolts on the sealing plate 13 from the cylinder 11, and then pushes the sealing plate 13 downward. During the downward movement of the sealing plate 13, the long rod 54 is driven downward, and the scraper 55 fixed to the top of the long rod 54 is driven downward. During the downward movement of the scraper 55, it can move downward along the inner cavity of the cleaning cylinder 51, so that the residue collected in the cleaning cylinder 51 can be pushed out of the cleaning cylinder 51;

[0065] When the cleaning barrel 51 rotates to clean the filter screen 3, since the scraper 55 is fixed to the sealing plate 13 by the long rod 54, the cleaning barrel 51 will rotate around the scraper 55. Since the runner 57 fixed to the guide rod 56 connected to the bottom of the scraper 55 is inscribed in the inner ring surface of the cleaning barrel 51, the runner 57 will be driven to rotate during the rotation of the cleaning barrel 51. At the same time, the runner 57 will drive the guide rod 56 and the auger blade 58 on the guide rod 56 to rotate. During the rotation of the auger blade 58, the residue entering the inner cavity of the cleaning barrel 51 through the feed trough 53 can be pushed downward, so that the residue is accumulated below the feed trough 53, preventing the residue from flowing out through the long trough 14 with the mixed liquid.

[0066] In a specific implementation process, the surface of the first semicircular ring 2 and the second semicircular ring 21 on the opposite side is rotatably connected to the driven rod 32 below the filter screen 3;

[0067] The outer surface of the driven rod 32 is fixedly connected to a support plate 33;

[0068] Specifically, since the surface of the opposite side of the first semicircular ring 2 and the second semicircular ring 21 is located below the filter screen 3 and is rotatably connected to the driven rod 32, the existence of the driven rod 32 can support the passing filter screen 3 to prevent the filter screen 3 from being torn due to excessive pressure. At the same time, since the driven rod 32 is fixedly connected to the support plate 33, the driven rod 32 can be driven to rotate during the cyclic rotation of the filter screen 3, so the driven rod 32 will drive the support plate 33 to rotate. During the rotation of the support plate 33, the filter screen 3 can be pushed to a raised state. When the filter screen 3 is raised, the raised filter screen 3 will push the residue to move, so that the residue can better follow the movement of the filter screen 3.
