Referring to fig. 1 and 2, an empty bucket washing device 440 according to an embodiment of the present invention is applied to a drinking water bucket cleaning apparatus 400 for washing a drinking water bucket 100 with a disinfectant. The drinking-water bucket cleaning apparatus 400 is used to clean the drinking-water bucket 100. In the present embodiment, the drinking-water bucket 100 includes a bucket body 110, a bucket bottom 120 disposed at the bottom of the bucket body 110, a bucket mouth 130 disposed at the upper portion of the bucket body 110, and a bucket shoulder 140 disposed between the bucket body 110 and the bucket mouth 130. In the present embodiment, the drinking-water bucket 100 has an axisymmetrical shape, which is rotatable along its own central axis.

The empty tub washing device 440 includes a swing tub device 443, a disinfectant washing nozzle 444, and a bung sterilizing nozzle 445.

The swing device 443 functions to rotate the drinking-water bucket 100. Specifically, during the actual operation, the inlet 130 of the drinking-water bucket 100 is rotated downward and around the central axis thereof. 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, the rotary device 443 may be a clamp, or a suction cup, or a top ring to rotate the drinking-water bucket 100 about its central axis. For example, when the barrel rotating device 443 is a clamp, the barrel rotating device 443 can clamp the barrel body 110 of the drinking water barrel 100, and the drinking water barrel 100 can be rotated by rotating the barrel rotating device 443. When the rotary barrel device 443 is a suction cup, the rotary barrel device 443 can vacuum-adsorb the bottom 120 of the drinking water barrel 100, and the drinking water barrel 100 can also be rotated by rotating the rotary barrel device 443. In this embodiment, the drum device 443 includes a top ring 4431. In operation, the top ring 4431 of the rotating device 443 can be inserted into the groove of the bottom 120 of the drinking water bucket 100 to rotate the drinking water bucket 100. Specifically, the top ring 4431 of the barrel rotating device 443 can press the groove on the bottom 120 of the drinking water barrel 100, and the barrel cup 448 is driven by rotating the barrel rotating device 443, so that the drinking water barrel 100 rotates synchronously. The top ring 4431 of the rotating barrel device 443 may be made of a silicone or polyurethane material, so that after the top ring 4431 contacts the bottom 120 of the drinking water barrel 100, a certain friction force is formed with the bottom 120, thereby effectively driving the drinking water barrel 100 to rotate. The top ring 4431 may also be shaped as a truncated cone or a pyramid, as needed, so as to be easily fitted into the groove of the bottom 120 of the drinking water bucket 100. In the present embodiment, the inlet 130 of the drinking-water bucket 100 faces downward, and the rotating device 443 is disposed above the bottom of the drinking-water bucket 100 and rotates the drinking-water bucket 100.

The disinfectant flushing nozzle 444 is used for extending into the drinking water bucket 100 to flush the disinfectant on the inner wall of the drinking water bucket 100. In this example, the pressure of the disinfectant flush was 5 bar. The disinfectant can kill bacteria in the drinking water bucket. During the washing process, the disinfectant can cover all areas of the inner wall of the drinking water bucket 100. The disinfectant can be peracetic acid, chlorine dioxide, etc.

The bung disinfection nozzle 445 is disposed outside the drinking water bucket 100 and is used for disinfecting the bung 130 of the drinking water bucket 100. In actual use, the bung sterilization nozzle 445 sprays a disinfectant 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. Specifically, the bung sterilization nozzle 445 may be a cone-shaped nozzle that emits a cone-shaped spray pattern. In this embodiment, the bung disinfection nozzle 445 is disposed obliquely, and the bung disinfection nozzle 445 is disposed at a height lower than the bung 130 of the drinking water bucket 100. The outlet of the spout sterilizing nozzle 445 faces the outer wall of the spout 130 of the drinking water bucket 100. Referring to fig. 3, the empty tub flushing device 440 further includes a first support rod 446 and a second support rod 447. The first support rod 446 is horizontally disposed, and the second support rod 447 is disposed parallel to the first support rod 446. The plurality of the bung sterilization nozzles 445 are provided on the first and second support rods 446 and 447, respectively. In the present embodiment, a projection of the bung 130 of the drinking-water bucket 100 in a vertical direction is located between the first support rod 446 and the second support rod 447.

Since the drinking water bucket 100 is continuously rotated during the washing process, even if the disinfectant sprayed from the bung disinfection nozzle 445 only covers a part of the outer wall of the bung 130, the bung disinfection nozzle 445 can completely disinfect the outer wall of the bung 130 during one rotation of the drinking water bucket 100, thereby improving the disinfection effect of the empty bucket washing device 400.

The empty tub flushing device 400 also includes a sanitizer flush pump 442, as desired. The disinfectant flushing pump 442 is connected to the disinfectant flushing nozzle 444 and the bung disinfection nozzle 445, and is configured to provide a disinfectant for flushing to the disinfectant flushing nozzle 444 and the bung disinfection nozzle 445. Specifically, the empty tub washing device 400 further includes a disinfectant accommodating groove 441. One end of the disinfectant flushing pump 442 is connected to the disinfectant containing tank 441. The other end of the disinfectant flushing pump 442 is connected to the disinfectant flushing nozzle 444 and the bung disinfection nozzle 445 for supplying the disinfectant in the disinfectant containing tank 441 to the disinfectant flushing nozzle 444 and the bung disinfection nozzle 445. In this embodiment, the disinfectant containing groove 441 is located below the opening 130 of the drinking water barrel 100 and is used for receiving the disinfectant dropped from the drinking water barrel 100 due to gravity in the flushing process.

The empty bucket flushing device 400 also includes a bucket cup 448. The barrel cup 448 is sleeved on the opening 130 of the drinking water barrel 100 during cleaning and rotates together with the drinking water barrel 100. In one aspect, the barrel cup 448 is sleeved on the opening 130 of the drinking water barrel 100 during cleaning, so that the disinfectant flushing nozzle 444 can accurately extend into the drinking water barrel 100 to flush the disinfectant on the inner wall of the drinking water barrel 100. On the other hand, the bucket cup 448 has the function of supporting the bucket to stand upside down and also assists in driving the drinking water bucket 100 to rotate. As required, the barrel cup 448 is provided with a bearing and a ball, so that the barrel cup 448 and the drinking water barrel 100 can be prevented from being worn or scratched when rotating synchronously, and the rotation of the barrel is more stable. According to the requirement, the barrel-rotating device 443 can also be arranged in a way of ascending and descending, and in the working process: when the empty tub advances to the designated position, the swing tub device 443 moves down to press the bottom of the tub, and then the swing tub device 443 starts to rotate. Since the barrel cup 448 is a rotating bottle cup (the ball rotates), the empty barrel rotates together due to the downward pressure of the upper barrel rotating device 443. When the spraying operation is completed, the rotary barrel device 443 is lifted again to remove the barrel pressing limitation, and the empty barrel continues to move to the next process.

The bung sterilization spray 445 is not limited to the above embodiments as required. Referring to fig. 4, another embodiment of the present invention provides a nozzle 445, which includes a plurality of liquid outlets 4451. The plurality of liquid outlets 4451 are directed to different drinking-water buckets 100, respectively. In this embodiment, the bung sterilization nozzle 445 is a four-hole nozzle. The bung disinfection nozzles 445 are disposed between two adjacent rows of drinking water buckets 100. The four holes of the bung disinfection nozzle 445 simultaneously spray the disinfectant to disinfect the bungholes 130 of the adjacent two drinking-water buckets 100 of each row. By setting the bung sterilization nozzle 445 to a four-hole nozzle, the number of nozzles can be reduced.

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 6 degrees, the corresponding water 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. 7. 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. In 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 of the opening of the drinking water barrel 100 along with the process return 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.

Step four: the inner wall of the drinking water bucket 100 is washed with alkali liquor as shown in fig. 9. 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 bacteria in the barrel and can soften, loosen and emulsify sediments on the inner wall of the drinking water barrel 100, and therefore 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 solution can be alkalescent solution such as sodium hypochlorite, potassium hypochlorite, calcium hypochlorite and the like according to requirements. The concentration range of the alkali liquor is 300ppm to 1000 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. 10. 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. 11. The pressure of the disinfectant flush is a first pressure. During the disinfectant washing process, the disinfectant washing nozzle 444 is inserted into the drinking-water bucket 100. The disinfectant is washed on the inner wall of the drinking-water bucket 100 by the disinfectant washing nozzle 444 using the first pressure. The disinfectant may sterilize bacteria in the drinking-water bucket 100 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. As required, a bung disinfection nozzle 445 is further disposed near the bung 130 of the drinking water bucket 100, and the bung disinfection nozzle 445 sprays a disinfectant onto an outer wall surface of the bung 130 to kill bacteria 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 bung sterilization nozzle 251 may be a cone-shaped nozzle that emits a cone-shaped spray pattern. When the plurality of drinking water buckets 100 are washed with the disinfectant, the nozzle 445 may sterilize the outer wall surfaces of the nozzles 130 of the plurality of drinking water buckets 100 at a time.

Step seven: the inner wall of the drinking water tub 100 is flushed with finished water, as shown in fig. 12. 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 purified water used for filling is to completely remove the disinfectant remaining in the disinfectant washing process to prepare 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. 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. A bung cleaning nozzle 455 is further disposed near the bung 130 of the drinking water bucket 100, as required, and the bung cleaning nozzle 455 is used for spraying the finished water onto the outer wall surface of the bung 130 to clean 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 finished water, thereby realizing an effective cleaning process. The bunghole cleaning spray head 455 may be a conical spray head that emits a conical spray pattern. When the plurality of drinking-water buckets 100 are flushed with the product water, the nozzle 455 may flush the outer wall surface of the mouths 130 of the plurality of drinking-water buckets 100 at one time. In this embodiment, the tub opening cleaning shower 455 is provided on the third support bar 454.

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. Also, 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 of the washing process can be improved, so that every portion 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.

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 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.
