Description

Technical Field

[0001] The utility model relates to the technical field of automatic car washers, in particular to a three-stage floating and sinking purification tank for a circulating water system of a car washer. Background Technique

[0002] With the development of social economy, the number of cars is increasing continuously, and the car wash industry has gradually emerged. The traditional manual car wash method not only takes time and effort but also wastes water resources. Therefore, automatic car washers are widely welcomed because of their time-saving and labor-saving features and good car wash effects. However, automatic car washers consume a large amount of water resources during the car wash process. Usually, it takes 100-150 liters of water to wash a car, which not only increases the cost but also puts pressure on the environment. Therefore, the design of the circulating water system of the car washer is particularly important to achieve the recycling and conservation of water resources.

[0003] After retrieval, the text of the publication number "CN219355342U" mentions that "the utility model discloses a circulating water system for a car wash pipeline. In the circulating water system for a car wash pipeline, a pair of water retaining walls extend along the driving direction of the car to be washed and are arranged at intervals; an infrared induction device is fixed on the water retaining wall and faces the interval between the pair of water retaining walls; a drainage ditch is horizontally connected to the pair of water retaining walls and the drainage ditch has a predetermined slope; a pair of annular galvanized pipes are respectively fixed on the upper surface of the water retaining wall, and a plurality of water outlet nozzles are fixed on the annular galvanized pipe and the spraying direction faces the car to be washed located between the pair of water retaining walls. The water supply pipe is in liquid communication with the annular galvanized pipe, and the water pump is connected to the water supply pipe; the sedimentation tank is in liquid communication with the drainage ditch". When in use, the sedimentation tank includes a primary sedimentation tank in liquid communication with the drainage ditch, a secondary sedimentation tank in liquid communication with the primary sedimentation tank, and a tertiary sedimentation tank in liquid communication with the secondary sedimentation tank. The tertiary sedimentation tank can be connected to the water supply pipe in a switchable manner. The utility model has a square steel grid with a curved bottom surface and good cleaning effect. However, the existing circulating water system of the car washer usually requires a pre-dug reservoir, which not only increases the installation workload but also limits the movement, disassembly, and assembly of the car washer and its auxiliary equipment. In addition, the existing circulating water system often only performs simple decontamination treatment when treating sewage, with poor cleaning degree, easy to block the water outlet of the car washer, and at the same time, the existing circulating water system is not automatically processed, and the processing efficiency is low.

[0004] Therefore, we provide a three-stage floating and sinking purification tank for a circulating water system of a car washer to solve the above problems. Content of the Utility Model

When in use, the liquid level sensor 21 can observe the current water level height in real time. When the internal water level drops, the liquid level sensor 21 can remind the outside to inject sewage again, thus preventing sewage from flowing out of the purified water outlet valve 23.

[0027] Further, the stainless steel inner tank 22 is welded to the purification tank 1, and the stainless steel inner tank 22 is closely attached to the purification tank 1. When in use, the stainless steel inner tank 22 has good corrosion resistance and is suitable for long-term filtering operations without worrying about leakage caused by corrosion.

[0028] Further, the floating matter filtering component 24 includes a filter net 241, a floating and sinking tank 242, a dissolved air release device 243, an exhaust pipe 244, a sewage discharge pipe 245, and a water inlet pipe 246. A filter net 241 is provided at the top inside of the stainless steel inner tank 22, and a floating and sinking tank 242 is screw-connected to the upper side of the purification tank 1. When in use, the filter net 241 can block the foam generated by car washing and lighter floating matters, thus facilitating the separation of floating matters and preventing impurities from mixing in the purified water.

[0029] Further, a dissolved air release device 243 is installed at the top of the floating and sinking tank 242, and an exhaust pipe 244 is installed at the lower end inside the dissolved air release device 243. When in use, the dissolved air release device 243 releases a large number of fine bubbles into the water through the exhaust pipe 244.

[0031] Embodiment 2

[0032] Please refer to Figure 1 、 Figure 2 、 Figure 3 and Figure 4As shown in the figure, as another implementation mode of the present utility model compared with the first comparative example, a sedimentation assembly 3 is installed on the lower side of the purification tank 1.

[0033] Working principle: Move a three-stage floating and sinking purification tank for the car wash machine circulating water system to the working position. When in use, first, place the purification tank 1 on an external steel frame, and then pour sewage into the stainless steel inner tank 22 in the purification tank 1 from the water inlet pipe 246. Second, the filter screen 241 filters out foam and floating objects and confines them in the floating and sinking tank 242. At the same time, the dissolved air release device 243 injects air bubbles into the sewage through the exhaust pipe 244. The bubbles carrying particles also float into the floating and sinking tank 242, while the sludge slowly accumulates in the sedimentation tank 31 due to gravity. After purification, first discharge impurities such as floating objects from the sewage discharge pipe 245, and then discharge the purified water from the purified water outlet valve 23. When the water level is low, the liquid level sensor 21 senses it and notifies external personnel or equipment to pour sewage again from the water inlet pipe 246, and the sludge discharge pump 32 discharges the sludge in the sedimentation tank 31 in advance. Finally, after repeating the filtration through four groups of the same equipment, the filtration effect is achieved, and thus the use process of a three-stage floating and sinking purification tank for the car wash machine circulating water system is completed.
