[0002] During the production and processing of milk powder, the use of a milk powder storage and sealing tank is of great significance. Since milk powder has strong moisture absorption, once it absorbs moisture in the air, it is prone to caking and deterioration. By promptly putting the produced milk powder into the milk powder storage and sealing tank, it can effectively prevent the milk powder from getting damp before being packaged. At the same time, putting the milk powder into the milk powder storage and sealing tank also provides convenience for the storage and transportation of milk powder. In order to avoid the growth of microorganisms and the mixing of impurities, the inside of the milk powder storage and sealing tank needs to be cleaned after being used for a period of time.

[0003] Chinese Patent CN112407642B discloses a storage tank, which can clean the inner wall of the tank when needed by arranging a cleaning component on the inner wall of the tank.

[0004] Since strict control of contamination is required when storing milk powder, and after the cleaning component arranged inside the tank body finishes brushing the inner wall of the tank body, the surface of the cleaning component is often prone to residual contamination that cannot be easily removed. When using a storage tank with a cleaning component arranged inside to store milk powder, it is likely to have an adverse impact on the storage of milk powder due to the contamination adhered to the cleaning component. Therefore, in the prior art, the milk powder storage tanks in milk powder processing plants usually still use the method of manually opening the tank for cleaning. The method of manually opening the tank for cleaning is not only time-consuming and laborious, but also prone to the situation of improper sealing after cleaning, causing trouble in the use of the milk powder storage tank.

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0022] Embodiment 1

[0023] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 7 and Figure 10 , the present invention provides a milk powder storage sealing can that can be cleaned without opening, including a can body 1, a sealing can cleaning component is provided on the can body 1, the sealing can cleaning component includes an installation cylinder 2, a scraping wall and removing adhesion mechanism 3 and a spraying and disinfecting mechanism 4, and the installation cylinder 2 is installed at the upper end of the can body 1; The scraping wall and removing adhesion mechanism 3 includes a rotating lifting column 31, a fixture 32, a scraping wall plate 33, a rotating lifting control component 34, an automatic opening component 35 and an elastic support component 36, and the scraping wall plate 33 is installed on the fixture 32; The rotating lifting control component 34 includes a slide seat 341, the slide seat 341 is rotatably connected to the rotating lifting column 31, and the slide seat 341 can only move up and down relative to the installation cylinder 2; The automatic opening component 35 includes a rotating arm 351 and an expanding spring 352, the rotating arm 351 is rotatably installed on the rotating lifting column 31, and the rotating arm 351 is rotatably connected to the fixture 32, and the expanding spring 352 is used to make the rotating arm 351 rotate and open, so that the fixture 32 abuts against the inner wall of the can body 1; The elastic support assembly 36 is used to make the clamp 32 close to the inner wall of the tank body 1; The spraying and disinfecting mechanism 4 includes a straight tube 41 and a nozzle 42. The straight tube 41 is rotatably sleeved inside the rotating lifting column 31, and the nozzle 42 is fixedly installed at the lower end of the straight tube 41. A feed pipe 11 , a discharge pipe 12 and a manhole 13 are installed on the tank body 1 .

[0024] As can be seen from the above, the sealed milk powder storage tank can be cleaned without opening the tank body 1 by providing the mounting cylinder 2, the scraping and de-sticking mechanism 3 and the spraying and disinfecting mechanism 4. When the tank body 1 is normally used to store milk powder, the scraping and de-sticking mechanism 3 and the spraying and disinfecting mechanism 4 can be prevented from contacting the milk powder, thereby avoiding contamination of the milk powder. At the same time, by providing the rotating lifting column 31, the clamp 32, the scraping plate 33, the rotating lifting control component 34, the automatic opening component 35 and the elastic support component 36, when the rotating arm 351 moves to the bottom of the mounting cylinder 2, with the support of the opening spring 352, the blade surface of the scraping plate 33 is in close contact with the inner wall of the tank body 1. When the rotating lifting control component 34 controls the rotating lifting column 31 to rotate and lift, the scraping plate 33 can be in contact with the inner wall of the tank body 1 and scrape off the sticky milk powder. In combination with the cleaning liquid sprayed from the nozzle 42, the interior of the tank body 1 can be effectively cleaned and disinfected.

[0025] When the milk powder storage sealed tank is used normally, the rotating lifting control component 34 is used to control the rotating lifting column 31 and the rotating arm 351 to the inside of the tank installation cylinder 2. At this time, the scraper plate 33 can also approach the top of the tank body 1. By setting the height of the feeding pipe 11 lower than the height of the scraper plate 33 at this time, it is possible to prevent milk powder from covering the scraper plate 33. When the inside of the tank body 1 is cleaned, the rotating lifting control component 34 is used to control the rotating lifting column 31 to descend. When the rotating lifting column 31 descends and the rotating arm 351 is away from the installation cylinder 2, the spring 3 is opened. 52 causes the rotating arm 351 to rotate and open, at which time the scraper plate 33 can be close to the inner wall of the tank body 1, and when the rotary lifting control component 34 continues to control the descent and rotation, the scraper plate 33 can gradually descend during the rotation, thereby achieving the effect of brushing the inner wall of the tank body 1, and in conjunction with the arrangement of the straight pipe 41 and the nozzle 42, the inner wall of the tank body 1 can be sprayed with water for flushing; in addition, before the milk powder storage sealed tank is used, it is also necessary to remove the residual moisture inside the tank body 1 by blowing in hot air, etc., which can be achieved by ventilation through the feed pipe 11.

[0026] Embodiment 2

[0027] like Figure 2 , Figure 4 , Figure 5 , Figure 7 , Figure 9 and Figure 10As shown in the figure, the difference between this embodiment and the above-mentioned embodiment is that the sliding seat 341 includes a top plate 3411, a bottom plate 3412, a connecting rod 3413 and a collar 3414. The lower surface of the top plate 3411 and the upper surface of the bottom plate 3412 are fixedly connected by the connecting rod 3413. The collar 3414 is fixedly installed on the lower surface of the bottom plate 3412. The upper end of the rotary lifting column 31 is fixedly installed with a rotary ring 311, and the rotary ring 311 is rotatably connected to the collar 3414.

[0028] As can be seen from the above, since the collar 3414 is fixed to the bottom plate 3412, the rotary ring 311 is fixed to the upper end of the rotary lifting column 31, and the rotary ring 311 is rotatably connected to the collar 3414, when the sliding seat 341 moves up and down, it can drive the rotary lifting column 31 to move up and down, and the rotary lifting column 31 can rotate freely.

[0029] The rotary lifting control assembly 34 further includes a driving motor 342, a driving gear 343 and an internal gear ring 344. The driving motor 342 is fixedly installed on the bottom plate 3412. The driving gear 343 is arranged between the bottom plate 3412 and the rotary lifting column 31, and the driving gear 343 is fixedly connected to the driving end of the driving motor 342. The internal gear ring 344 is fixedly installed on the rotary lifting column 31, and the internal gear ring 344 is meshed with the driving gear 343.

[0030] As can be seen from the above, since the sliding seat 341 is rotatably connected to the rotary lifting column 31, and the internal gear ring 344 is fixedly installed on the rotary lifting column 31, when the driving motor 342 drives the driving gear 343 to rotate, it drives the internal gear ring 344 meshed with the driving gear 343 to rotate, thereby controlling the rotation of the rotary lifting column 31.

[0031] The rotary lifting control assembly 34 further includes a cylinder 345. The cylinder 345 is fixedly installed on the mounting cylinder 2, and the driving end of the cylinder 345 penetrates through the top wall of the mounting cylinder 2 and extends into the interior of the mounting cylinder 2 and is fixedly connected to the top plate 3411.

[0032] As can be seen from the above, when the driving end of the cylinder 345 expands and contracts, it can control the top plate 3411 to move up and down, thereby controlling the lifting of the sliding seat 341.

[0033] The spraying and disinfection mechanism 4 further includes a hose 43. The lower end of the hose 43 is fixedly connected to the upper end of the straight pipe 41. The straight pipe 41 is fixedly connected to the bottom plate 3412. A notch 3415 is formed on the top plate 3411, and a jack 21 is formed on the mounting cylinder 2. The hose 43 penetrates through the notch 3415 and the jack 21 and extends to the outside of the mounting cylinder 2.

[0034] As can be seen from the above, by providing the top plate 3411, the bottom plate 3412 and the connecting rod 3413, the axis of the top plate 3411 is connected to the driving end of the air cylinder 345, so that the straight pipe 41 and the rotary lifting column 31 can be coaxially arranged, making the pulling force on the air cylinder 345 from the sliding seat 341 more balanced. At the same time, the straight pipe 41 will not shift during the rotation of the rotary lifting column 31. In addition, by providing the notch 3415 and the jack 21, the hose 43 can extend above the top plate 3411 through the notch 3415, so that the hose 43 can extend more into the interior of the mounting cylinder 2 when the rotary lifting column 31 moves downward.

[0035] Embodiment III

[0036] As Figure 4 , Figure 5 , Figure 6 and Figure 8 shown, the difference between this embodiment and the above embodiments is that the automatic opening assembly 35 further includes a slide bar 354, a lifting seat 355 and a spreading plate 356. A groove 312 is formed in the side surface of the rotary lifting column 31, and a through hole 313 is formed in the bottom of the groove 312. The slide bar 354 passes through the through hole 313 and extends to the inside of the groove 312. The lifting seat 355 is movably arranged below the rotary lifting column 31, and the upper surface of the lifting seat 355 is fixedly connected to the slide bar 354. The spreading spring 352 is sleeved on the slide bar 354, and the two ends of the spreading spring 352 are respectively fixedly connected to the lower surface of the rotary lifting column 31 and the upper surface of the lifting seat 355. The spreading plate 356 is rotatably installed on the lifting seat 355, and the spreading plate 356 is rotatably connected to the middle of the rotating arm 351.

[0037] As can be seen from the above, since the slide bar 354 passes through the through hole 313 and extends to the inside of the groove 312, the slide bar 354 is slidably connected to the rotary lifting column 31. Since the two ends of the spreading spring 352 are respectively fixedly connected to the lower surface of the rotary lifting column 31 and the upper surface of the lifting seat 355, when the rotary lifting column 31 rises and the rotating arm 351 contacts the bottom of the mounting cylinder 2, the rotating arm 351 gradually approaches the vertical. At this time, the spreading spring 352 is stretched, and the slide bar 354 and the lifting seat 355 move downward relative to the rotary lifting column 31, causing all the clamps 32 to approach each other. Conversely, when the rotary lifting column 31 descends, the spreading spring 352 contracts by itself, causing the slide bar 354 and the lifting seat 355 to move upward relative to the rotary lifting column 31, and the rotating arm 351 gradually opens.

[0038] A chute 314 is formed in the inner wall of the groove 312, and a slider 353 is slidably connected in the chute 314. The slider 353 is fixedly connected to the slide bar 354.

[0039] As can be seen from the above, by providing the chute 314 and the slider 353, the stability of the movement of the slide bar 354 and the lifting seat 355 can be improved.

[0040] The elastic support assembly 36 includes a guide rod 361, a sliding block 362, a support spring 363 and a support rod 364. The guide rod 361 is fixedly installed on the swing arm 351. The sliding block 362 is slidably installed on the guide rod 361. The support spring 363 is sleeved on the guide rod 361, and both ends of the support spring 363 are fixedly connected to the guide rod 361 and the sliding block 362 respectively. Both ends of the support rod 364 are rotatably connected to the sliding block 362 and the clamp 32 respectively; When the support spring 363 is relaxed, the length direction of the clamp 32 is collinear with the length direction of the swing arm 351.

[0041] As can be seen from the above, when the swing arm 351 approaches the inner wall of the tank body 1, the clamp 32 contacts the inner wall of the tank body 1 earlier than the swing arm 351. Then, as the swing arm 351 continues to open, the lower end of the clamp 32 cannot continue to move outwards, causing the sliding block 362 to slide on the guide rod 361, and the support spring 363 to be stretched, so that the clamp 32 gradually approaches the vertical state.

[0042] Embodiment 4

[0043] As Figure 1 、 Figure 5 and Figure 6 shown, the difference between this embodiment and the above embodiments is that the clamp 32 includes a clamping plate 321 and a bolt 322. The clamping plate 321 is rotatably connected to both side surfaces of the swing arm 351 respectively. Installation holes are provided on both the clamping plate 321 and the scraping wall plate 33. The scraping wall plate 33 is detachably installed between the clamping plates 321 through the bolt 322. A buffer rubber pad 323 is further provided on one side wall of the clamping plate 321 facing the scraping wall plate 33.

[0044] As can be seen from the above, the scraping wall plate 33 fixedly clamped between the clamping plates 321 through the bolt 322 can firmly fix the scraping wall plate 33. By providing the buffer rubber pad 323, the probability of the buffer rubber pad 323 being broken or crushed can be reduced.

[0045] A flange installation pipe 14 is fixedly installed at the upper end of the tank body 1. The installation cylinder 2 is inserted into the flange installation pipe 14, and a flange ring 22 is fixedly installed on the installation cylinder 2. The flange ring 22 is detachably fixed to the flange installation pipe 14.

[0046] As can be seen from the above, since the installation cylinder 2 is inserted into the flange installation pipe 14, after the tank body 1 is cleaned, the sealed tank cleaning component can be removed from the flange installation pipe 14, and then the upper end of the flange installation pipe 14 can be sealed, which can not only further prevent the impurities remaining on the sealed tank cleaning component from contaminating the inside of the tank body 1, but also facilitate the cleaning of the sealed tank cleaning component.

[0047] Although embodiments of the present invention have been shown and described, those of ordinary skill in the art will appreciate that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
