The disinfectant in the disinfectant accommodating groove 441 can be recycled.

The drinking-water bucket cleaning apparatus 400 further includes a plurality of drip-drying devices (not shown) as necessary. One or more dripping devices are arranged between the rinsing device 410 and the pre-rinsing device 420, or between the pre-rinsing device 420 and the alkali rinsing device 430, or between the alkali rinsing device 430 and the disinfectant rinsing device 440, or between the disinfectant rinsing device 440 and the finished water rinsing device 450. A second pre-rinsing device 460 may be further included between the lye rinsing devices 430 and the disinfectant rinsing device 440, as desired. At this time, a plurality of dripping devices can be further included between the lye flushing device 430 and the second pre-flushing device 460; or a plurality of drip-dry devices may be included between the second pre-flush device 460 and the sterilant flush device 440.

The drinking water bucket cleaning apparatus 400 further includes a plurality of bucket rotating devices (not shown) as necessary. The barrel rotating device is arranged above one or more of the pre-washing spray head 210, the alkali liquor washing spray head 240, the disinfectant washing spray head 250 and the finished product water washing spray head 260 and is used for enabling the drinking water barrel 100 to rotate.

Referring to fig. 2, in an actual operation process, the cleaning process of the drinking water barrel cleaning apparatus 400 includes the following steps:

the method comprises the following steps: the drinking-water bucket 100 is rotated about its central axis with the bucket mouth 130 facing downward. The reason why the drinking-water bucket 100 is disposed with the bucket opening 130 facing downward is that: when the drinking water barrel 100 is cleaned, the corresponding washing water or cleaning liquid moves downward due to gravity and flows out of the barrel opening 130 of the drinking water barrel 100, so that the cleaned washing water or cleaning liquid is not required to be poured out by an additional process. Specifically, there are various ways to rotate the drinking-water bucket 100 about its central axis. For example, the body 110 of the drinking water bucket 100 may be clamped by a clamp, and the drinking water bucket 100 may be rotated by rotating the clamp. For another example, the bottom 120 of the drinking water bucket 100 may be vacuum-sucked by using a suction cup, and the drinking water bucket 100 may be rotated by rotating the suction cup.

Step two: the inner wall of the drinking-water bucket 100 is rinsed as shown in fig. 3. The pressure of the rinsing is a first pressure. In this embodiment, the first pressure range is 3bar to 8 bar. Specifically, during the rinsing process, the rinsing nozzle 210 is disposed near the bung 130 of the drinking-water bucket 100. The rinse spray 210 is a conical spray. The water jet angle of the rinsing nozzle 210 ranges from 3 degrees to 5 degrees. The inner wall of the drinking water bucket 100 is rinsed by the spray head with the pressure of 3-8 bar, the rinsing process can be firstly performed on the inner wall of the drinking water bucket 100 for preliminary wetting, so that the adhesion between dirt and the inner wall of the drinking water bucket 100 is reduced, and the removal effect of the subsequent cleaning process on the dirt is effectively improved. Specifically, the spraying area of the rinsing nozzle 210 does not need to cover all areas of the inner wall of the drinking water bucket 100, and only needs to spray to the bottom 120 of the drinking water bucket 100. Since the drinking water barrel 100 continuously rotates in the rinsing process, the liquid sprayed to the bottom 120 of the drinking water barrel 100 moves to the region of the barrel body 110 of the drinking water barrel 100 due to the centrifugal force, and then flows downward from the inner wall of the barrel body 110 due to the gravity, sequentially flows through the shoulder 140 and the bung 130, and is discharged to the external environment through the bung 130. By this arrangement, even if the water jet angle of the rinsing nozzle 210 is in the range of 3 to 5 degrees, the corresponding water flow can wet all regions of the inner wall of the drinking-water bucket 100. In this embodiment, the washing water used by the rinsing device 410 is the process water (second return water) generated during the rinsing process of the second pre-rinsing device 460.

Step three: the inner wall of the drinking-water bucket 100 is pre-washed as shown in fig. 4. The pressure of the pre-flush is a second pressure. In the pre-washing process, the pre-washing nozzle 220 extends into the drinking water barrel 100, and the second pressure is greater than the first pressure. In this embodiment, the second pressure range is 50bar to 80 bar. In this step, since the second pressure (50bar-80bar) used by the washing water shower 220 is much greater than the first pressure (3bar-8bar) used by the rinsing water shower 210. During the pre-washing process, the washing water at the second pressure can effectively wash dirt on the inner wall of the drinking water barrel 100, so that the dirt is separated from the inner wall of the drinking water barrel 100 and flows out from the opening of the drinking water barrel 100 along with the process water. In addition, since the previous rinsing process has preliminarily wetted the inner wall of the drinking-water bucket 100, the adhesion of the corresponding dirt to the bucket wall is reduced by the wetting process, so that the corresponding dirt, residue and dust can be more effectively removed during the pre-washing process. Specifically, referring to fig. 5, the pre-washing nozzle 220 includes a support rod 221, and a first nozzle 222, a second nozzle 223 and a third nozzle 224 disposed on the support rod 221. A liquid passage is formed inside the supporting bar 221 so that the washing water supplied from the water pump can be transmitted to the first spray head 222, the second spray head 223 and the third spray head 224 through the liquid passage. The supporting rod 221 is movably disposed below the spout 130 of the drinking water barrel 100 to drive the first nozzle 222, the second nozzle 223 and the third nozzle 224 to extend into the drinking water barrel 100. In this embodiment, the washing water used by the pre-washing nozzle 220 is the process return water (first return water) generated by the product water washing device 450 during the washing process.

As required, the first spray head 222, the second spray head 223 and the third spray head 224 are fan spray heads. The fan-shaped spray head can spray a planar fan-shaped water flow to strongly wash the inner wall surface of the drinking water bucket 100. Specifically, the first nozzle 222 is disposed on the top of the supporting rod 221. The water jet direction of the first nozzle 222 is upward to jet a fan-shaped water jet in a planar shape to the area of the bottom 120 of the drinking water bucket 100, so as to flush dirt on the bottom 120 of the drinking water bucket 100. The second spray head 223 is disposed between the first spray head 222 and the third spray head 224, and the height of the second spray head 223 is slightly lower than the height of the first spray head 222. The water spray direction of the second spray head 223 is upward and laterally to spray a fan-shaped water spray in a planar shape to the bottom 120 area of the drinking water bucket 100 and/or the upper area of the inner wall of the bucket body 110. In the present embodiment, since the drinking-water bucket 100 is inverted, an upper region of an inner wall of the body 110 is disposed near the bottom 120. The third spray head 224 is disposed below the second spray head 223. The water spray direction of the third spray head 224 is downward and sideward to spray a fan-shaped water spray in a planar shape to the lower region of the body 110 and/or the shoulder 140 of the drinking water bucket 100. In the present embodiment, since the drinking-water bucket 100 is inverted, a lower region of the tub body 110 is disposed near the bung 130. The fan-shaped angle of the planar fan-shaped water flow spray sprayed by the first spray head 222, the second spray head 223 and the third spray head 224 ranges from 45 degrees to 90 degrees as required. If necessary, the planes of the fan-shaped water sprays sprayed from the first spray head 222, the second spray head 223 and the third spray head 224 are arranged perpendicular to the horizontal plane. The area of the tub bottom 120 covered by the planar fan-shaped water flow spray that can be sprayed by the first spray head 222 overlaps with the area of the tub bottom 120 covered by the planar fan-shaped water flow spray that can be sprayed by the second spray head 223; the area of the tub 110 that can be covered by the fan-shaped flat water spray that can be sprayed by the second spray head 223 overlaps with the area of the tub 110 that can be covered by the fan-shaped flat water spray that can be sprayed by the third spray head 224. Therefore, the planar fan-shaped water sprays sprayed by the first spray head 222, the second spray head 223 and the third spray head 224 can flush and scrape the inner wall of the drinking water barrel 100 in all directions without dead angles, so as to remove dirt in the drinking water barrel 100.

It is to be understood that the positions where the first spray head 222, the second spray head 223 and the third spray head 224 are disposed are not limited to the above-described embodiment. Referring to fig. 6, a pre-flush nozzle 230 according to another embodiment is provided. The pre-rinse spray head 230 includes a support bar 231, and a first spray head 232, a second spray head 233, and a third spray head 234 disposed on the support bar 231. A liquid passage is formed inside the supporting bar 231 so that the washing water supplied from the water pump can be transferred to the first spray head 232, the second spray head 233 and the third spray head 234 through the liquid passage. The supporting rod 231 is movably disposed below the spout 130 of the drinking water barrel 100 to drive the first nozzle 232, the second nozzle 233 and the third nozzle 234 to extend into the drinking water barrel 100. The first spray head 232, the second spray head 233 and the third spray head 234 are fan spray heads. The fan-shaped spray head can spray a planar fan-shaped water flow to strongly wash the inner wall surface of the drinking water bucket 100. The first spray head 232 is disposed on the top of the support bar 231. The second spray head 233 is disposed between the first spray head 232 and the third spray head 234. The third spray head 234 is disposed at a lower height than the second spray head 233. Unlike the above embodiment, the plane of the fan-shaped water spray generated by the first spray head 232 is still perpendicular to the horizontal plane, but the central axis of the fan-shaped water spray is offset from the central axis of the drinking water barrel 100 by a predetermined angle, so that the fan-shaped water spray generated by the first spray head 232 only covers one side area of the barrel bottom 120 in the vertical cross section. In the present embodiment, the central axis of the fan-shaped water spray is offset from the central axis of the drinking-water bucket 100 by a predetermined angle of 30 to 60 degrees. Since the drinking water bucket 100 is continuously rotated during the pre-washing process, after the drinking water bucket 100 rotates one turn, the entire area of the bucket bottom 120 can be washed by the first spray head 232. In this embodiment, the fan-shaped water sprays from the first spray head 232, the second spray head 233 and the third spray head 234 are all located on the same plane. The fan-shaped water sprays from the first spray head 232, the second spray head 233 and the third spray head 234 may not be on the same plane, if necessary. Referring to fig. 7, the plane of the fan-shaped water spray generated by the first nozzle is perpendicular to the plane of the fan-shaped water spray generated by the second nozzle 233 and the third nozzle. The plane on which the fan-shaped water sprays from the second spray head 233 and the third spray head 234 are positioned is not necessarily disposed through the central axis of the support rod 231, if necessary. Referring to fig. 7, the planes of the fan-shaped water sprays sprayed by the second spray head 233 and the third spray head 234 are tangential to the outer circumferential surface of the support rod 231. At this time, the fan-shaped water sprays from the second spray head 233 and the third spray head 234 may be inclined at a certain angle with respect to the inner wall of the drinking-water bucket 100, thereby removing dirt more effectively. Referring to fig. 8, in another embodiment, the pre-flush nozzle 230 may further include a first telescopic rod 235 and a second telescopic rod 236. One end of the first telescopic rod 235 is connected to the supporting rod 231, and the other end is connected to the second nozzle 233. One end of the second telescopic rod 236 is connected to the supporting rod 231, and the other end is connected to the third nozzle 234. During the pre-flushing process, the first telescopic rod 235 and the second telescopic rod 236 may respectively drive the second spray nozzle 233 and the third spray nozzle 234 to move towards the direction close to the inner wall of the barrel body 110 of the drinking water machine water barrel 100. In one aspect, the second spray head 233 and the third spray head 234 are close to the inner wall of the tub 110, and the water flow thereof has a stronger washing force. On the other hand, the fan-shaped water sprays from the second and third spray heads 233 and 234 are inclined with respect to the inner wall surface of the drinking-water bucket 100, and the water flow washing effect is improved. The fan-shaped water spraying directions of the second spray nozzle 233 and the third spray nozzle 234 are opposite to the rotation direction of the drinking water tub 100 as needed to achieve a better dirt removing effect. Referring to fig. 9, in another embodiment of the present invention, the supporting rod 221 further includes a first gap 2211 and a second gap 2212, the second nozzle 223 is disposed on the first gap 2211, and the third nozzle 224 is disposed on the second gap 2212. The first and

second slits

2211 and 2212 are provided in the support rod 221 in order to adjust the water jet directions of the second and

third nozzles

223 and 224 by adjusting the inclination angles of the side surfaces of the first and

second slits

2211 and 2212. It is understood that the top end of the supporting rod 221 is further provided with an inclined surface 2213, and the first nozzle 222 is arranged on the inclined surface 2213. Similarly, the inclined surface 2213 can also adjust the water jet direction of the first nozzle 222.

Step four: the inner wall of the drinking water bucket 100 is washed with alkali liquor as shown in fig. 10. The pressure of the alkali liquor washing is a third pressure. In the alkali washing process, the alkali washing nozzle 240 extends into the drinking water bucket 100, and the third pressure is smaller than the second pressure and greater than the first pressure. In this embodiment, the third pressure range is 20bar to 35 bar. The inner wall of the drinking water barrel 100 is washed by the alkali liquor through the spray head with the third pressure (20-35 bar), the alkali liquor can kill part of microorganisms in the barrel, and meanwhile, sediments on the inner wall of the drinking water barrel 100 can be softened, loosened and emulsified, so that dirt which is not easy to wash clean in the pre-washing process is removed. And, since the pre-washing has been performed at the second pressure (50bar-80bar), the third pressure used during the lye washing may be lower than the second pressure. However, since the sprayed water flow is also required to wash and wipe the dirt softened by the alkali liquor during the alkali liquor washing process, the third pressure used needs to be greater than the first pressure used during the rinsing process. In this embodiment, the temperature of the lye ranges from 55 ℃ to 65 ℃ to enhance the cleaning effect of the lye washing. The alkali liquor can be alkaline cleaning agent such as sodium hydroxide and potassium hydroxide according to the requirement. The concentration range of the alkali liquor is determined according to the use requirement of the product. For example, the concentration of the ultra-concentrated alkaline cleaner is generally 1000 to 1500 ppm.

In the process of washing with the alkali liquor, the washing pressure of the alkali liquor washing spray head 240 is 20bar-35 bar. In order to raise the rinsing pressure to 20-35 bar as soon as possible, the pressure is raised and spraying is performed during the raising of the lye rinsing nozzles 240, instead of waiting until reaching a specific position inside the drinking water bucket 100 and then raising the pressure. The mode can effectively improve the spraying time of the lye washing. Specifically, when the alkaline washing nozzle 240 is inserted into the drinking water tank 100 and then the pressure is raised, the effective spraying time of the alkaline washing is about 12 seconds. In this embodiment, if the pressure is increased and the alkali washing nozzle 240 is sprayed during the lifting process, the effective spraying time for the alkali washing is increased to about 13 seconds.

Step five: the drinking water barrel 100 after the alkali liquor washing is subjected to a second pre-washing, as shown in fig. 11. The pressure of the second pre-flushing is also the second pressure, namely 50bar-80 bar. In the second pre-washing process, the second pre-washing nozzle 461 extends into the drinking water barrel 100 to scrape the inner wall of the drinking water barrel 100. The second pre-rinsing step is provided for the purpose of: on one hand, the residual alkali liquor in the alkali liquor washing process of the drinking water bucket 100 is removed, so as to avoid the influence of the residual alkali liquor on the disinfectant liquid used in the subsequent disinfectant washing step; on the other hand, the second pre-rinsing step may also use high-pressure washing water (50bar-80bar) to flush dirt on the inner wall of the drinking water barrel 100, so that the dirt is separated from the inner wall of the drinking water barrel 100 and flows out of the opening of the drinking water barrel 100 along with the process water. In this embodiment, a second backflow water collecting device 462 is further disposed at the bottom of the second pre-washing nozzle 461, and is used for collecting the process water generated during the use of the second pre-washing device 460 to form second backflow water. The drinking-water bucket cleaning apparatus 400 further includes a third reflux pump 463. The third reflux pump 463 is connected between the second reflux water collecting device 462 and the rinsing device 410, and is used for supplying the second reflux water in the second reflux water collecting device 462 to the rinsing device 410. That is, the process water generated in the second pre-rinsing process may be used as the washing water used by the rinsing device 410, thereby improving the utilization efficiency of the washing water by the drinking-water bucket cleaning apparatus 400. The washing water used by the second pre-washing nozzle 461 is the process water (first return water) generated by the product water washing device 450 during the washing process, as required.

Step six: the inner wall of the drinking water tub 100 is subjected to disinfectant washing as shown in fig. 12. The pressure of the disinfectant flush is a first pressure. During the disinfectant washing process, the disinfectant washing nozzle 250 extends into the drinking water tub 100. The disinfectant is washed on the inner wall of the drinking-water bucket 100 by using the disinfectant nozzle 250 of the first pressure. The disinfectant can kill bacteria in the drinking water bucket again. And, since the washing water having the second pressure (50bar-80bar) and the alkali solution having the third pressure (20bar-35bar) are washed, the inner wall of the drinking water barrel 100 does not need to be washed in the disinfectant washing process, and only the disinfectant can cover all areas of the inner wall of the drinking water barrel 100. Therefore, the pressure used for rinsing the disinfectant is the same as the rinsing pressure used for rinsing, and is the first pressure. In this embodiment, the disinfectant may be peracetic acid, chlorine dioxide, or the like.

Step seven: the inner wall of the drinking water tub 100 is flushed with finished water, as shown in fig. 13. The pressure of finished water washing is a first pressure. In the product water washing process, the product water washing nozzle 260 extends into the drinking water tub 100. The purpose of washing the inner wall of the drinking water bucket 100 with the sterile water used for filling is to completely remove the residual disinfectant in the disinfectant washing process in preparation for the next filling process. In this embodiment, a first backflow water collecting device 451 is disposed below the product water flushing nozzle 260. The first backwater collecting device 451 is used for collecting the process water generated during the use of the product water washing device 450 to form the first backwater. The drinking-water bucket washing device 400 further comprises a first return pump 452 and a second return pump 453. The first backflow pump 452 is connected between the first backflow water collecting device 451 and the pre-washing device 420, and is configured to provide the first backflow water in the first backflow water collecting device 451 to the pre-washing device 420. The second recirculation pump 453 is connected between the first recirculation water collecting device 451 and the second pre-washing device 460, and is used for providing the first recirculation water in the first recirculation water collecting device 451 to the second pre-washing device 460.

In the process of pre-washing, washing with alkali liquor, washing with disinfectant and washing with finished product water, the pre-washing nozzle 220 the alkali liquor washing nozzle 240 the disinfectant washing nozzle 250 and the finished product water washing nozzle 260 all extend into the inside of the drinking water bucket 100. Will the pre-flush shower nozzle 220 the alkali lye shower nozzle 240 the disinfectant wash shower nozzle 250 with the finished product water wash shower nozzle 260 stretch into to the purpose of the inside of drinking water bucket 100, the pre-flush shower nozzle 220 the alkali lye shower nozzle 240 the disinfectant wash shower nozzle 250 with the finished product water wash shower nozzle 260 with the distance of the bucket wall of drinking water bucket 100 is closer. In the process of flushing the inner wall of the drinking water bucket 100 by using the high-pressure water flow of the second pressure and the third pressure, the corresponding flushing force is stronger, and the cleaning effect is better. Moreover, since the body of the drinking water bucket 100 is continuously rotated about its own central axis during the pre-washing, the alkali washing, the disinfectant washing, and the finished water washing, the uniformity and the comprehensiveness of the washing process can be improved, so that each part of the inner wall of the drinking water bucket 100 can be washed. The structures of the alkali liquid washing nozzle 240, the disinfectant washing nozzle 250 and the finished water washing nozzle 260 may be the same as or similar to the structures of the pre-washing nozzle 220 or the pre-washing nozzle 230, and are not described herein again.

If necessary, in the process of performing disinfectant washing on the inner wall of the drinking water barrel 100 in the sixth step, disinfectant washing may be performed on the outer wall surface of the barrel opening 130 of the drinking water barrel 100. As shown in fig. 12, an auxiliary sterilizing nozzle 251 is further disposed near the bung 130 of the drinking water bucket 100, and the auxiliary sterilizing nozzle 251 sprays a sterilizing agent onto the outer wall surface of the bung 130 to kill microorganisms on the outer wall surface of the bung 130. Since the drinking water bucket 100 is in the process of continuous rotation, when the drinking water bucket 100 rotates for one circle, all parts of the outer wall surface of the bucket opening 130 can be sprayed by the disinfectant, thereby realizing an effective disinfection process. The auxiliary sterilizing spray head 251 may be a conical spray head which sprays a conical spray shape. The spray head may also be in a direct spray form or a dispersed spray form, as desired. When the spray head is in a direct-injection mode, only one hole is formed in the spray head, and the spray head directly sprays water columns to be scattered at four positions behind a target point. When the spray head is in a scattering spray mode, the spray head is provided with a plurality of holes and the water sprayed by the spray head can scatter according to a certain shape layout. When the plurality of drinking water buckets 100 are washed with the disinfectant, the auxiliary sterilizing nozzle 251 may sterilize the outer wall surfaces of the mouths 130 of the plurality of drinking water buckets 100 at a time.

If necessary, in the process of performing the finished water washing on the inner wall of the drinking water barrel 100 in the seventh step, the finished water washing may be performed on the outer wall surface of the barrel opening 130 of the drinking water barrel 100. As shown in fig. 13, a finished product spout nozzle 261 is further disposed near the spout 130 of the drinking water bucket 100, and the finished product spout nozzle 261 sprays the finished product water onto the outer wall surface of the spout 130 to clean the spout 130. Since the drinking water bucket 100 is in the process of continuous rotation, when the drinking water bucket 100 rotates for one circle, all parts of the outer wall surface of the bucket opening 130 can be sprayed by the finished water, thereby realizing an effective cleaning process. The finished water bucket mouth 261 may be a conical nozzle that emits a conical spray pattern. The spray head may also be in a direct spray form or a dispersed spray form, as desired. When the spray head is in a direct-injection mode, only one hole is formed in the spray head, and the spray head directly sprays water columns to be scattered at four positions behind a target point. When the spray head is in a scattering spray mode, the spray head is provided with a plurality of holes and the water sprayed by the spray head can scatter according to a certain shape layout. When the finished water flushing is performed together with the plurality of drinking water buckets 100, the finished water bucket port nozzle 261 may flush the outer wall surface of the bucket ports 130 of the plurality of drinking water buckets 100 at a time.

Between each rinsing step, a drip drying step may also be included, as desired. The dripping step is used for ensuring that the liquid used in the previous flushing process does not influence the next flushing process as much as possible.

And performing standard process design on the rinsing step, the pre-rinsing step, the alkali liquor rinsing step, the disinfectant rinsing step, the finished product water rinsing step and the dripping drying step as required. In this embodiment, the rinsing step and the pre-rinsing step are a single process; the alkali liquor washing step and the finished product water washing step are three procedures; the disinfectant washing step comprises four working procedures. The duration of each process is between 18 seconds and 21 seconds. In this example, the duration of each pass was 19.6S.

The second procedure: the drinking water bucket 100 is transferred to a rinsing station to perform a rinsing process. The inner wall of the drinking water bucket 100 is rinsed by the rinsing nozzle 210 with the pressure of 3bar-8bar, and the inner wall of the drinking water bucket 100 can be preliminarily wetted in the rinsing process so as to reduce the adhesion between dirt and the inner wall of the drinking water bucket 100. In this step, the actual rinsing time of the rinse nozzle 210 is 12S or more.

The third procedure: the drinking water bucket 100 is transferred to a pre-rinsing station to perform a pre-rinsing process. The inner wall of the drinking water barrel 100 is pre-flushed by a pre-flushing nozzle 220 with a pressure of 50bar-80bar, so as to effectively flush dirt on the inner wall of the drinking water barrel 100, so that the dirt is separated from the inner wall of the drinking water barrel 100 and flows out from the barrel opening 130 of the drinking water barrel 100 along with process water. When the drinking water bucket 100 is transferred to the pre-washing station, the pre-washing nozzle 220 sprays high-pressure water flow and moves up to the inside of the drinking water bucket 100. When the pre-washing time is close to the end, the pre-washing nozzle 220 sprays the high-pressure water and moves down to the outside of the drinking water barrel 100, so that the drinking water barrel 100 can move to the next process. In this process, the actual rinsing time of the pre-rinse nozzle 220 is greater than or equal to 11S.
