On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thoroughly and comprehensively understood.

[0043] It should be noted that when an element is referred to as being "disposed on" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and do not represent the only implementation method.

[0044] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the technical field of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0045] The utility model provides a tank cleaning device 100. Figure 1 As shown, the tank cleaning device includes an outer shell 10, a detergent storage tank 20, a city water storage tank 30, and a clean water storage tank 40 which are arranged in sequence at the bottom of the outer shell 10, and a tank body 70 is suspended inside the outer shell 10 through a suspension structure 90 and connected to a track 80 through the suspension structure 90, and a spray pipe 50 and an air knife pipe 60 are respectively connected to the inner side of the outer shell 10.

[0046] The utility model provides another implementation mode, such as Figure 2 As shown, in order to adapt to tanks of different sizes, the spray pipe 50 adopts a local lifting design. The spray pipe 50 includes a fixed spray pipe section 51 and a liftable spray pipe section 52, so as to better fit the size of the tank to prevent the spray pipe 50 from being too long or too short. If the spray pipe 50 is too long, it will cause waste of nozzles and thus waste of water; if the spray pipe 50 is too short, it will be unable to clean the unsuitable tank 70.

[0047] Preferably, the length of the fixed spray pipe section 51 in the spray pipe 50 is 1.5-2.5 times the length of the liftable spray pipe section 52. More preferably, the length of the fixed spray pipe section 51 is twice the length of the liftable spray pipe section 52.

[0048] Preferably, the spraying rate of the spray pipe 50 is adjusted by PLC.

[0049] The utility model provides another implementation mode, such as Figure 3 As shown, a liquid level monitoring device 41 is provided in the clean water storage tank 40, and water is automatically replenished when the water level in the clean water storage tank 40 is lower than half of the height of the clean water storage tank 40.

[0050] Preferably, a liquid level monitoring device 41 is provided in the clean water storage tank 40, and water replenishment is stopped when the water level in the clean water storage tank 40 is between two-thirds and three-quarters of the height of the clean water storage tank 40.

[0051] Preferably, a heating rod 21 and a temperature monitoring device 22 are provided in the detergent storage tank 20 to keep the water temperature in the detergent storage tank 20 between 40 and 60 degrees Celsius, making it easier to clean dirt such as oil, grease, and particles. Too high a temperature will cause water to evaporate and turn into water vapor, which will have a significant impact on the working environment and the life of the equipment, and will waste water. Too low a temperature will not be able to fully dissolve the detergent, resulting in low efficiency and failure to effectively clean the tank body 70.

[0052] Preferably, a concentration detection device 23 is provided in the detergent storage tank 20 for detecting the concentration of the detergent in the detergent storage tank 20. When the concentration ranges from 3% to 15%, preferably from 3% to 10%, a flushing agent needs to be added if the concentration is lower than 3%, and water needs to be added if the concentration is higher than 15%. If the concentration of the detergent is low, the dirt on the surface of the tank body 70 cannot be cleaned. In the actual process, the concentration of the detergent needs to be adjusted according to the type of detergent.

[0053] like Figure 4 As shown, the suspension structure 90 includes a suspension hanger 91 and a rotating structure 92. The tank body 70 is slidably connected to the track 80 through the suspension hanger 91, which facilitates the feeding and unloading of the tank body, is more automated, saves labor costs, is more automated, and avoids bumps caused by manual handling. The rotating structure 92 is connected to the suspension hanger 91, and the tank body 70 rotates through the rotating structure 92, so that every corner of the tank body surface is rinsed clean and there is no dead corner. The rotation rate is controlled by a programmable controller (PLC). The rotation rate is continuously adjusted according to the different tank bodies 70 and the degree of cleaning required, and needs to be coordinated with the spray flow and pressure of the spray pipe 50.

[0054] Please see attached Figure 5 , the cleaning device 100 is powered by the electric control box 12. The fixed spray pipe section 51 is fixedly connected to the inner wall of the shell 10, and the liftable spray pipe section 52 is movably connected to the inner wall of the shell 10, that is, the liftable spray pipe section 52 can slide up and down on the inner wall. The wind knife pipe 60 is similar to the spray pipe 50 structure, and is also divided into a fixed wind knife pipe section 61 and a liftable wind knife pipe section 62, and the fixed wind knife pipe section 61 is fixedly connected to the inner wall of the shell 10, and the liftable wind knife pipe section 62 is movably connected to the inner wall of the shell 10, wherein the hot air water cutting is controlled by a high-pressure water cutting fan 63 and a heating system, and the heating system is connected to the high-pressure water cutting fan, and the high-pressure water cutting fan 63 is arranged outside the shell 10. Among them, the liftable spray pipe section 52 and the liftable wind knife pipe section 62 are adjusted up and down by a servo moving mechanism 53. Preferably, the fixed spray pipe section 51 and the fixed air knife pipe section 61 are adjusted forward and backward by the servo mechanism 53, so as to be closer to the tank body 70, so as to prevent the waste of resources caused by incomplete flushing and incomplete water removal due to being too far away. Preferably, the length of the fixed air knife pipe section 61 is 1.5-2.5 times that of the liftable air knife pipe section 62, and more preferably 2 times.

[0055] Preferably, the spray pipe 50 and the air knife pipe 60 are designed in a contoured manner, which is a bracket-shaped design, so as to better fit the shape of the tank body 70 .

[0056] In addition, by Figure 5 It can be seen that a special-shaped box 11 is provided at the bottom of the cleaning device 100, and the special-shaped box 11 is used for the water circulation process. Figure 5 In the first step, the detergent water after cleaning the tank body 70 is collected in the special-shaped box body 11 through the pipeline, and is controlled by the liquid exchange pneumatic valve 24 to return the detergent water to the detergent storage tank 20; in the second step, the city water is collected in the special-shaped box body 11 after flushing, and then circulated back to the city water storage tank 30 through the liquid exchange pneumatic valve 31; in the third step, the clean water is collected after rinsing, and in order to keep the clean water in the clean water storage tank 40 clean, the collected clean water is circulated back to the city water storage tank 30. Preferably, a heating rod 111 is provided in the special-shaped box body 11 to keep the circulating water at 40-60 degrees Celsius, making it easier to clean the tank body 70. In addition, Figure 5 It can be seen that the spray pipe 50 is connected to the detergent storage tank 20, the city water storage tank 30 and the clean water storage tank 40 respectively and can be switched back and forth according to the program through the liquid replacement pneumatic valve 54, so that the tank body 70 is cleaned in sequence according to the steps.

[0057] For further explanation, please refer to Figure 6 The cleaning device 100 also includes a filter 13 and a spray pump 14. Before the water in the special-shaped box 11 circulates through the spray pump 14 and enters the detergent storage tank 20 or the city water storage tank 30, it needs to pass through the filter 13 to filter out dirt such as oil, grease, and particles in the sewage to prevent the detergent storage tank 20 or the city water storage tank 30 from being contaminated again, thereby ensuring that the water in the spray tank 70 is pollution-free.

[0058] The cleaning device 100 described in the utility model is more suitable for tanks 70 of different sizes by making a partial lifting design and a bracket-shaped design for the spray pipe 50; through the connection design of the detergent storage tank 20, the municipal water storage tank 30, the clean water storage tank 40 and the special-shaped box 11, water is fully recycled and utilized, greatly saving water resources and costs; and by adopting a rotating design for the tank 70, manual transportation of the tank 70 during the cleaning process is avoided, and collisions during transportation are prevented, thereby being more in line with industrial production.

[0059] The utility model provides a method for cleaning by adopting the tank cleaning device, comprising S1: lotion flushing; S2: city water flushing; S3: clean water flushing; S4: wind knife water cutting; and also comprising a circulating water system, wherein the water after the S1 lotion flushing is collected and recycled to a lotion storage tank, the water after the S2 city water flushing is collected and recycled to a city water storage tank; the water after the S3 clean water flushing is collected and recycled to the city water storage tank, the water in the city water storage tank overflows to the lotion storage tank, the water in the lotion storage tank overflows and is discharged, and the clean water storage tank adopts a water replenishment setting, through which the water is continuously circulated, thereby saving water resources and costs.

[0060] For more details, please refer to Figure 7 When the tank enters the cleaning device, the first step is to use the detergent in the detergent storage tank to perform high-pressure spray flushing on the tank through the spray pipe to remove oil, grease, particles and other dirt on the surface of the bottle; the second step is to use the municipal water in the municipal water storage tank to perform high-pressure spray flushing on the tank to remove the detergent and residual dirt; the third step is to use the clean water in the clean water storage tank to spray and rinse with a large flow rate to thoroughly remove the residual detergent and dirt on the surface of the tank; the fourth step is to use a high-pressure air knife to cut water and a hot air system to dry the tank, and finally transport it to the next process. In addition, in order to save water resources and reduce costs, a system for collecting circulating water in the cleaning process is designed in the above-mentioned detergent storage tank, city water storage tank and clean water storage tank. The detergent water in the first step is collected through a pipeline and returned to the detergent storage tank; in the second step, the city water is collected after flushing and circulated back to the city water storage tank; in the third step, the clean water is collected after rinsing. In order to keep the clean water in the clean water storage tank clean, the collected clean water is circulated back to the city water storage tank. When the clean water in the clean water storage tank is insufficient, it is replenished. Since the clean water after cleaning is circulated to the city water storage tank, the excess water in the city water storage tank overflows into the detergent storage tank, and the overflowing water in the detergent storage tank is discharged through the pipeline. This tank cleaning method greatly saves water resources and saves costs.

[0061] The above-mentioned embodiments only express several implementation methods of the utility model, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the utility model, and these all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
