[0019] As shown in Figure 1 A kind of ball ring cleaning device, including cleaning tank 4, heating mechanism 1 being arranged in the cleaning tank 4, water inlet pipeline 8 and lye delivery pipeline 5 being arranged in the upper end of the cleaning tank 4, waste lye collection tank 9 being communicated with the cleaning tank 4, drain pipe 2 being arranged in the bottom of the cleaning tank 4 one side, automatic lifting mechanism 7 being arranged outside the cleaning tank 4, filler frame 6 being driven left and right and up and down by the automatic lifting mechanism 7, the ball ring to be cleaned placed into the filler frame 6 is moved and cleaned by the automatic lifting mechanism 7, sewage in the cleaning tank 4 is discharged into sewage pool by the drain pipe 2, waste lye in the cleaning tank 4 is delivered into the waste lye collection tank 9 by connecting pipeline.

[0020] In actual use, the Pall ring is placed in the filler frame 6, the Pall ring fills two-thirds of the filler frame 6, and then the filler frame 6 filled with the Pall ring is lifted by the automatic lifting mechanism 7 and moved into the cleaning tank 4. Among them, the cleaning tank 4 is made of stainless steel plate for security, and the size is 1500MM*1500MM*1200MM. When the Pall ring is cleaned, first, the lye is injected into the cleaning tank 4 through the lye conveying pipeline 5, and a bucket of metal detergent is added during this process until the Pall ring is submerged, and then the lye conveying pipe input is closed; Then, the lye is heated by the heating mechanism 1 and soaked for about 20 hours, and the waste lye after cooling is conveyed to the waste lye collection tank 9 through the pipeline; Finally, clean the Pall ring by injecting fire water through the water inlet pipeline 8, and the waste water is discharged to the sewage station through the sewage pipe 2. The clean Pall ring is taken out of the cleaning tank 4 and stored for use, and the final cleaning waste lye can be directly recycled to the sewage station for use. The waste water is discharged to the sewage station for treatment. When the Pall ring is cleaned, the waste lye is used for cleaning, and then the fire water is used for rinsing again, which can effectively save water resources, make the utilization rate of lye higher, and no longer need to occupy the lye tank of the polyester cleaning filter. At the same time, during the cleaning process of the Pall ring, whether it is taken out or put in, it is operated by the automatic lifting mechanism 7, which is more convenient to operate, the number of Pall rings to be cleaned can be controlled, and the labor intensity is lower.

[0021] Further improvement is that the bottom of the cleaning tank 4 is provided with a low discharge valve 91 and a self-priming pump 92, and the waste lye in the cleaning tank 4 is conveyed to the waste lye collection tank 9 through the low discharge valve 91 and the self-priming pump 92.

[0022] Through the combination of the self-priming pump 92 and the low discharge valve 91, the waste lye in the cleaning tank 4 can be discharged more completely, avoiding excessive residual waste lye in the cleaning tank 4, which affects the cleanliness of the subsequent clean water cleaning.

[0023] Further improvement is that the heating mechanism 1 includes a steam main pipe 12 extending into the bottom along the side wall of the cleaning tank 4, a plurality of steam pipes 11 horizontally arranged at the bottom of the cleaning tank 4, and a switch valve 13 arranged on the steam main pipe 12, and the gas outlet of the steam pipe 11 is arranged upward.

[0024] When the lye is heated, the high-temperature steam is divided into each steam pipe 11 through the switch valve 13, and then the high-temperature gas is discharged through the gas outlet of the steam pipe 11 for heating. During the heating process, since the gas outlet of the steam pipe 11 is arranged upward, the lye in the cleaning tank 4 can be driven to flow, thereby realizing better cleaning of the Pall ring and avoiding the situation that the Pall ring is not cleaned.

[0025] Further improvement is that one side of the cleaning tank 4 is also provided with a magnetic flap liquid level meter 3.

[0026] Since the height of the cleaning tank 4 is about 1.5m and is made of stainless steel plate for security, the control of the liquid level by the operator is more troublesome, therefore, a magnetic flap liquid level meter 3 is installed on one side of the cleaning tank 4, through which the real-time liquid level can be more directly and reliably observed, avoiding the problems of incomplete cleaning caused by insufficient liquid level or overflow caused by too high liquid level.

[0027] Further improvement is that the automatic lifting mechanism 7 comprises a guide rail 71 and an electric hoist 72 arranged on the guide rail 71.

[0028] The automatic lifting mechanism 7 is composed of the guide rail 71 and the electric hoist 72, which has a simple and convenient overall structure and is more versatile, and the filler frame 6 can be lifted and moved left and right by the electric hoist 72, thereby facilitating the movement of the filler frame 6 and effectively solving the problem of difficulty in taking out the filler frame 6.

[0029] Further improvement is that the filler frame 6 is welded by a stainless steel filter plate, and the bottom of the filler frame 6 is provided with a bottom cover 62, the bottom cover 62 is a flip cover structure, and the bottom cover 62 can be flipped downward.

[0030] The filler frame 6 is welded by a stainless steel filter plate, which can be better cleaned, and the bottom of the filler frame 6 is provided with a bottom cover 62 that can be flipped downward, when the Paul ring cleaning is completed and needs to be stored, only the bottom cover 62 is opened, so that the cleaned Paul ring can flow out from the outlet at the bottom of the filler frame 6, effectively solving the problem of difficulty in taking out the filler frame 6 after cleaning.

[0031] Further improvement is that the bottom cover 62 and the side plate of the filler frame 6 are provided with a guide plate 61.

[0032] Since the filler frame 6 generally has a large volume, and the container opening for storing the Paul ring is limited, if the opening area of the bottom cover 62 is too large after being opened, it is easy to cause a large number of Paul rings to fall out after the bottom cover 62 is directly opened, therefore, the area of the bottom cover 62 is limited, but this causes some Paul rings to be easily retained at the bottom of the filler frame 6, in order to avoid the retention of the Paul rings in the filler frame 6, the bottom cover 62 and the side plate of the filler frame 6 are connected by the inclined guide plate 61, which can solve the problem of retention of the Paul rings and can shake the filler frame 6 at a certain angle during flat placement.

[0033] The above embodiments are only the preferred embodiments of the present application, and cannot be used to limit the scope of protection of the present application, and any non-essential changes and replacements made by those skilled in the art on the basis of the present application shall fall within the scope of protection of the present application.
