Description

Technical Field

[0001] This utility model belongs to the field of pure water equipment cleaning technology, specifically relating to a device for cleaning the inner wall of a pure water equipment storage tank. Background Technology

[0002] The cleaning of the inner wall of pure water equipment storage tank is a specialized cleaning process for pure water storage scenarios. Its core is to remove scale, microbial film, metal oxides and soluble residues attached to the inner wall of the storage tank, while avoiding the introduction of secondary pollution. It is based on the principles of "high cleanliness, no residue and suitability for pure water characteristics" and uses methods such as spraying, high pressure jet, mechanical scrubbing or ultrasonic synergy, combined with automated or auxiliary operation modes, to cover equipment of different volumes from small household water tanks to large industrial storage tanks.

[0003] However, the conventional method for cleaning the inner wall of pure water equipment storage tanks is to rinse with water. For stubborn stains, mechanical scrubbing is required. However, traditional mechanical scrubbing has obvious limitations. Its scrubbing structure and size are mostly fixed designs and cannot be flexibly adjusted according to the volume and height of the tank. When switching to clean storage tanks of different sizes, the device is difficult to fit precisely with the inner wall of the tank. Not only does it require the replacement of special parts or additional disassembly and adjustment, but it is also cumbersome and inefficient. In addition, it may leave cleaning dead corners due to insufficient fit, which not only affects the cleanliness standard of pure water storage, but also restricts convenient use in multiple scenarios.

[0004] To address the aforementioned issues, this application proposes a device for cleaning the inner wall of a pure water equipment storage tank. Utility Model Content

[0005] To address the aforementioned problems in the existing technology, this utility model provides a cleaning device for the inner wall of a pure water equipment storage tank, which features flexible adjustment of the scrubbing range and height and adaptability to storage tanks of different sizes.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a cleaning device for the inner wall of a pure water equipment storage tank, comprising a tank frame, a controller provided on the left side of the tank frame, a sliding column slidably connected inside the tank frame, electric push rods fixedly connected to both the front and back sides of the tank frame, the telescopic ends of the two electric push rods being fixedly connected to the front and back sides of the sliding column respectively, a rotary motor provided at the bottom end of the sliding column, a connecting block fixedly connected to the output end of the rotary motor, a rotating frame fixedly connected to both the front and back sides of the connecting block, and a connecting frame fixedly connected to the outer surface of each rotating frame;

[0007] Each of the rotating frames is equipped with a brake motor on its left side, and the output end of each brake motor is fixedly connected to the rotating shaft of the rotating frame. Each of the two connecting frames has a slotted shell on its opposite side, and a telescopic column is slidably connected inside each slotted shell. Each slotted shell has multiple telescopic rods inside, and the telescopic ends of the two telescopic rods are fixedly connected to the ends of the two telescopic columns that are close to each other. A sweeping frame is fixedly connected to the opposite ends of the two telescopic columns.

[0008] As a preferred embodiment of this utility model, a connecting plate is fixedly connected to the upper surface of the slot frame, and two sets of fixing holes are provided on the upper surface of the connecting plate.

[0009] As a preferred embodiment of this utility model, a mounting plate is fixedly connected to the right side of the controller, and the right side of the mounting plate is fixedly connected to the left side of the slot frame.

[0010] As a preferred embodiment of this utility model, a fixing frame is fixedly connected to the outer surface of the rotary motor, and the upper surface of the fixing frame is fixedly connected to the bottom end of the sliding column.

[0011] As a preferred embodiment of this utility model, each of the two brake motors is fixedly connected to a connecting seat on one side that is close to the other, and the right side of each connecting seat is fixedly connected to the left side of the rotating frame.

[0012] As a preferred technical solution of this utility model, a protective shell is fixedly connected to the left side of each of the rotating frames, and each of the protective shells is sleeved on the outside of the brake motor.

[0013] As a preferred technical solution of this utility model, a fixing plate is fixedly connected to one side of each of the two groove shells that are close to each other, and the side of each of the two fixing plates that are close to each other is fixedly connected to the side of each of the two connecting frames that are far apart from each other.

[0014] As a preferred embodiment of this utility model, each of the two multi-section telescopic rods has a fixed ring fixedly connected to one end of each other, and the two fixed rings have a fixed connection to the inner wall of the groove shell on one side of each other.

[0015] Compared with existing technologies, the advantages of this utility model are as follows: By setting a cooperative structure with multiple telescopic rods and telescopic columns, the horizontal extension distance of the cleaning frame can be flexibly adjusted to adapt to the cleaning needs of the inner walls of storage tanks of different volumes. This solves the problems of fixed size and poor adaptability of traditional mechanical scrubbing devices. At the same time, the sliding column is driven to move up and down by an electric push rod, and the rotating frame is driven to rotate 180 degrees forward and 180 degrees backward by a rotary motor. This enables full coverage scrubbing of the inner wall of the storage tank at different heights, avoiding cleaning dead corners. The angle of the rotating frame can be precisely controlled by a brake motor, allowing the device to be adjusted to facilitate entry into the tank through the opening, further improving the scrubbing fit. The overall structure is integrated and controlled by a controller, eliminating the need for disassembly, adjustment, or replacement of parts. This makes operation convenient and efficient. Furthermore, all contact parts can be made of corrosion-resistant materials, meeting the cleanliness requirements of pure water equipment without secondary pollution, significantly improving the practicality and cleaning effect of cleaning in multiple scenarios.

In this embodiment, the device can be fixed to the tank opening or the matching bracket by the cooperation of the connecting plate 4 and the fixing holes 5, so as to ensure the stability of the device during the cleaning process.

[0030] Specifically, a mounting plate 3 is fixedly connected to the right side of the controller 2. The right side of the mounting plate 3 is fixedly connected to the left side of the slot frame 1. In this embodiment, the mounting plate 3 enables the controller 2 and the slot frame 1 to be stably assembled, while reserving operating space to facilitate parameter adjustment and maintenance of the controller 2.

[0031] Specifically, a fixing frame 15 is fixedly connected to the outer surface of the rotary motor 14.

[0036] The working principle and usage process of this utility model are as follows: First, the entire device is fixed to the tank opening or the matching bracket using the connecting plate 4 and fixing hole 5 to ensure stable installation. Then, the controller 2 starts the brake motor 13 to adjust the angle of the rotating frame 9, causing the sweeping frame 21 to be in a retracted state, facilitating the device's insertion into the tank through the opening. After insertion, the controller 2 controls the brake motor 13 to adjust the angle of the rotating frame 9, causing the sweeping frame 21 to be in an extended state. Simultaneously, the controller controls the extension and retraction of the multi-section telescopic rod 18, driving the telescopic column 17 to slide along the tank shell 10 until the sweeping frame 21 precisely fits against the inner wall of the tank. Then, the rotary motor 14 is started to drive the rotating frame 9 and the connecting... The frame 12 and the sweeping frame 21 rotate 180 degrees forward and 180 degrees backward, and control the extension and retraction of the electric push rod 6 to drive the sliding column 7 to move up and down along the trough frame 1, so as to achieve full coverage cleaning of different heights and positions of the inner wall of the storage tank. During the cleaning process, the controller 2 links all components in real time to work together. The extension distance and cleaning angle of the sweeping frame 21 can be flexibly adjusted according to the size of the storage tank. Stubborn stains are efficiently removed by the PTFE scraper of the sweeping frame 21. After cleaning is completed, the sweeping frame 21 is first retracted by the multi-section telescopic rod 18, and then the brake motor 13 is adjusted to reset the rotating frame 9. Finally, the device is taken out from the opening of the storage tank. The whole process does not require disassembly of parts, which is convenient to operate and has no secondary pollution.
