[0055] The technical solution of the present invention is further described in conjunction with the following embodiments.

[0056] Example 1

[0057] A leak-proof cleaning device for a reactor, such as Figure 1 and Figure 2 As shown, a sealing shell 100, a magnetic drive mechanism 200 and a cleaning arm 300 which are sealed and assembled with the cleaning hole 620 of the external reaction kettle 600 are provided. The magnetic drive mechanism 200 is fixedly assembled on the outside of the sealing shell 100, and the cleaning arm 300 can be movably assembled on the inside of the sealing shell 100. The magnetic drive mechanism 200 is magnetically connected to the cleaning arm 300.

[0058] Before cleaning, the magnetic drive mechanism 200 moves downward, and the magnetic drive mechanism 200 drives the cleaning arm 300 to move downward by magnetic attraction, and makes the cleaning arm 300 extend from the cleaning hole 620 of the external reactor 600 into the interior of the external reactor 600.

[0059] After cleaning is completed, the magnetic drive mechanism 200 moves upward, and the magnetic drive mechanism 200 drives the cleaning arm 300 to move upward through magnetic attraction, and causes the cleaning arm 300 to retract as a whole into the inside of the sealing shell 100 .

[0060] It should be noted that the ground direction is defined as downward when the anti-leakage cleaning device is in normal use. The magnetic drive mechanism 200 of the present invention does not need to be mechanically connected to the cleaning arm 300, that is, the cleaning arm 300 can be extended and retracted in the sealed shell 100 by magnetic attraction, so the other hole of the sealed shell 100 is connected to the magnetic drive mechanism 200, thereby improving the sealing performance of the sealed shell 100, effectively preventing the internal gas leakage of the reactor 600 and having a higher explosion-proof performance.

[0061] The magnetic drive mechanism 200 is provided with a magnetic guide part 210, a magnetic slider 220 and a linear drive assembly 230. The linear drive assembly 230 is assembled on the outside of the sealed shell 100. The magnetic slider 220 is assembled on the linear drive assembly 230. The magnetic slider 220 is magnetically connected to the magnetic guide part 210. The magnetic guide part 210 is magnetically connected to the cleaning arm 300. Figure 3 .

[0062] The cleaning arm 300 is provided with a tube body 310 and a first magnetic member 320. The first magnetic member 320 is fixedly mounted on the outer end of the tube body 310, and the first magnetic member 320 is magnetically connected to the magnetic guide part 210. The magnetic guide part 210 is provided with a guide member 211 and a second magnetic member 212. The second magnetic member 212 is fixedly assembled inside the guide member 211, and the guide member 211 and the second magnetic member 212 are integrally slidably mounted on the outer side of the sealing shell 100, and the second magnetic member 212 is magnetically connected to the first magnetic member 320. Figure 4 .

[0063] It should be noted that the first magnetic part 320 and the second magnetic part 212 of the present invention can be a whole magnetic structure respectively, or the first magnetic part 320 and the second magnetic part 212 can be composed of multiple magnetic structures. The structures that can only realize the magnetic connection between the first magnetic part 320 and the second magnetic part 212, and the magnetic connection between the first magnetic part 320 and the magnetic slider 220 belong to the first magnetic part 320 and the second magnetic part 212 of the present invention.

[0064] The sealing shell 100 is provided with an outer sleeve 110, one end of the cleaning arm 300 is located inside the outer sleeve 110, and the other end of the cleaning arm 300 protrudes from the outer sleeve 110, the magnetic guide part 210 can be slidably mounted on the outer surface of the outer sleeve 110, and the linear drive component 230 is arranged parallel to the outer sleeve 110.

[0065] The sealing shell 100 is also provided with a sight hole tube 120 and a valve body 130 sealed and assembled with the cleaning hole 620 of the external reactor 600. The outer sleeve 110, the sight hole tube 120 and the valve body 130 are sealed and assembled from top to bottom. One end of the cleaning arm 300 is located inside the outer sleeve 110, and the other end of the cleaning arm 300 can move up and down along the inside of the outer sleeve 110, the inside of the sight hole tube 120 and the inside of the valve body 130. The valve body 130 of the present invention can be a ball valve or other valve bodies 130 that can be closed.

[0066] Before cleaning, the valve body 130 is opened, and the spray head 330 of the cleaning arm 300 enters the valve body 130 from the inside of the sight glass tube 120 , and then extends into the inside of the external reactor 600 from the cleaning hole 620 of the external reactor 600 .

[0067] After cleaning is completed, the spray head 330 of the cleaning arm 300 is located inside the sight glass tube 120, and the valve body 130 is closed.

[0068] It should be noted that the sight hole tube 120 of the present invention is used to observe the position of the cleaning arm 300, so as to accurately control the switch of the valve body 130. Moreover, after the cleaning is completed, the outer sleeve 110 and the sight hole tube 120 can be isolated from the reactor 600 through the valve body 130, so as to prevent the corrosive gas of the reactor 600 from entering the interior of the anti-leakage cleaning equipment, thereby extending the service life of the anti-leakage cleaning equipment. The spray head 330 of the present invention can be a two-dimensional rotating spray head 330 or a three-dimensional rotating spray head 330 rotated by liquid pressure, and the working principle and internal structure of such a spray head are common knowledge in the art, and will not be described one by one here.

[0069] The anti-leakage cleaning device of the present invention is also provided with a liquid inlet hard tube 400 and a locking mechanism 500 for locking the magnetic guide part 210. The locking mechanism 500 is fixedly assembled on the upper part of the sealing shell 100, and the locking mechanism 500 and the magnetic guide part 210 are detachably assembled; the liquid inlet hard tube 400 is fixedly sealed and connected with the liquid inlet (not shown in the figure) of the outer sleeve 110, and the side wall of the tube body 310 of the cleaning arm 300 is provided with a first liquid inlet hole 311, and the first liquid inlet hole 311 is located below the first magnetic member 320 of the cleaning arm 300; a cleaning liquid channel is formed between the liquid inlet hard tube 400, the liquid inlet and the first liquid inlet hole 311, such as Figure 6 and Figure 7The locking mechanism 500 is provided with a driving motor 510 and a latch 520. The driving motor 510 is fixedly assembled on the upper part of the sealing shell 100, and the latch 520 is drivingly connected to the driving motor 510. Figure 8 .

[0070] Before cleaning, the latch 520 is retracted inwardly and separated from the fixing hole of the magnetic guide 210 , thereby unlocking the magnetic drive mechanism 200 .

[0071] After cleaning is completed, when the magnetic drive mechanism 200 moves upward to the uppermost end of the sealing shell 100 , the latch 520 extends outward and is inserted into the interior of the fixing hole to lock the magnetic drive mechanism 200 .

[0072] Moreover, before, during or after cleaning, the first liquid inlet hole 311 is always located in the inner area of ​​the outer sleeve 110 .

[0073] It should be noted that the liquid inlet hard tube 400 of the present invention is fixedly assembled with the sealing shell 100, such as by welding, and the positions of the liquid inlet hard tube 400 of the present invention and the sealing shell 100 are fixed. Moreover, the liquid inlet hard tube 400 of the present invention is a hard tube, and compared with a soft tube, the sealing performance of the present invention is higher.

[0074] The sealing shell 100 is also provided with a limit tube 140 and a sealing plate 150. The limit tube 140 is assembled inside the outer sleeve 110 and is fitted on the outside of the cleaning arm 300. The limit tube 140 is also fixed to the sight hole tube 120. The sealing plate 150 is fixedly assembled on the upper part of the sight hole tube 120. The outer sleeve 110 is sealed on the upper surface of the sealing plate 150. The cleaning arm 300 is sealed and passes through the sealing plate 150, and slides up and down along the assembly hole of the sealing plate 150.

[0075] The side wall of the limiting tube 140 is provided with a plurality of second liquid inlet holes 141, such as Figure 5 As shown, the flow direction of the cleaning liquid is from front to back through the liquid inlet hard tube 400, the liquid inlet, the second liquid inlet hole 141 and the first liquid inlet hole 311.

[0076] It should be noted that the function of the position limiting tube 140 of the present invention is to prevent the cleaning arm 300 and the first magnetic member 320 from moving down to the liquid inlet of the outer sleeve 110 , thereby blocking the liquid inlet hard tube 400 .

[0077] The working principle of the anti-leakage cleaning device of the present invention is as follows: before cleaning, the valve body 130 is opened to allow the outer sleeve 110 and the sight hole tube 120 to pass through the reactor 600, and then the locking mechanism 500 unlocks the magnetic drive mechanism 200, and the linear drive component 230 drives the magnetic slider 220 to move downward, so that the magnetic guide part 210 and the cleaning arm 300 move downward as a whole, and the tube body 310 and the spray head 330 extend to the interior of the reactor 600; during cleaning, the cleaning liquid enters the cleaning arm 300 from the liquid inlet hard pipe 400 and is sprayed to the interior of the reactor 600; after cleaning, the linear drive component 230 drives the magnetic slider 220 to move upward, so that the magnetic guide part 210 and the cleaning arm 300 move upward as a whole, and the tube body 310 and the spray head 330 are stored in the outer sleeve 110 and the sight hole tube 120, and then the valve body 130 is closed, and the locking mechanism 500 locks the magnetic guide part 210 at the same time.

[0078] The anti-leakage cleaning device for the reactor can automatically extend into the reactor 600 for cleaning, thereby reducing labor input, and can also avoid completely opening the manhole, which can effectively prevent the leakage of harmful gases. More importantly, there is no mechanical connection between the cleaning arm 300 and the magnetic drive mechanism 200 inside the sealed shell 100 of the present invention, but the cleaning arm 300 is driven by contactless magnetic attraction, thereby ensuring the sealing of the sealed shell 100, effectively preventing the leakage of gas inside the reactor 600 and having a high explosion-proof performance.

[0079] Example 2

[0080] A reaction kettle 600, such as Fig. 9 As shown, a kettle body 610 and a pair of anti-leakage cleaning devices of Example 1 are provided, a pair of cleaning devices for the reaction kettle 600 are respectively mounted on two cleaning holes 620 of the kettle body 610, and a pair of anti-leakage cleaning devices are respectively located on both sides of the stirring paddle 630 of the kettle body 610. Fig. 9 The kettle body 610 in FIG. 1 is a perspective view.

[0081] It should be noted that, in order to avoid obstruction by the stirring paddle 630 , a pair of cleaning devices are provided for the reaction kettle 600 in this embodiment to ensure full coverage cleaning of the kettle body 610 .

[0082] The reactor 600 can be automatically extended into the reactor 600 for cleaning by the anti-leakage cleaning device, thereby reducing labor input, and avoiding completely opening the manhole, which can effectively prevent the leakage of harmful gases. More importantly, there is no mechanical connection between the cleaning arm 300 and the magnetic drive mechanism 200 inside the sealed shell 100 of the present invention, but the cleaning arm 300 is driven by contactless magnetic attraction, thereby ensuring the sealing of the sealed shell 100, effectively preventing the leakage of gas inside the reactor 600 and having a high explosion-proof performance.

[0083] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit the scope of protection of the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the present invention.
