Technical Field
[0001] This utility model belongs to the field of white water pipe cleaning technology, specifically relating to a cleaning device for the inner wall of a white water system pipe. Background Technology
[0002] In industries such as papermaking and textiles, white water recycling systems are widely used. Over long-term operation, the inner walls of these pipes easily accumulate mixed contaminants composed of fibers, organic sludge, inorganic scale, and microbial biofilms. These contaminants are complex in composition and firmly attached, especially the inorganic scale, which is hard and difficult to remove. Currently, PIG (pipe cleaning ball) cleaning technology is a common method for cleaning the interior of longer pipes. Its principle is to use clean water or compressed air as propulsion to drive cleaning balls made of polymer materials such as polyurethane through the pipe, cleaning the pipe surface through the interaction between the ball and the pipe... The friction and squeezing action of the inner wall scrapes away dirt; however, traditional PIG cleaning technology has obvious limitations: First, the friction between the cleaning ball and the inner wall of the pipe is mainly physical, which has limited cleaning effect on stubborn inorganic salt scale and dense biofilm, and is difficult to completely remove; Second, white water pipes in industrial sites have a variety of different pipe diameters due to process requirements, while the size of traditional PIG cleaning balls is fixed. One size of cleaning ball can only be used for pipes with a specific inner diameter, which lacks versatility. This leads to users needing to equip themselves with cleaning balls of various sizes, increasing the cost of use and the complexity of operation and maintenance. Utility Model Content

Simultaneously, a storage tank holds specialized chemical agents, which, combined with the multi-nozzle design of the high-pressure cleaning head, first soften stubborn stains such as inorganic salt deposits and microbial films through spraying, and then are scraped off by the steel bristles of the PIG cleaning ball. This effectively solves the problem that traditional PIG cleaning technology, relying solely on friction, is insufficient to remove various contaminants. Furthermore, the device employs a main control box and casters, enabling intelligent control and convenient movement. Its compact structure and simple operation not only enhance cleaning efficiency and thoroughness but also reduce labor costs and equipment maintenance frequency, making it suitable for pipe maintenance in various industrial white water systems.

Example
[0018] The high-pressure cleaning head 7 is connected to the storage tank 3 via a water supply pipe 73. The high-pressure cleaning head 7 is equipped with a first nozzle 72 and a second nozzle 71. The first nozzle 72 is used to spray high-pressure water to disperse debris at the front end of the device. Multiple second nozzles 71 are arranged in a ring and tilted, used to spray chemical agents from the storage tank 3 to soften stubborn scale. The water supply pipe 73 connects the high-pressure cleaning head 7 and the storage tank 3, and the flow rate and pressure are controlled by the main control box 2. Due to the ring-shaped arrangement of the second nozzles 71, the high-pressure cleaning head 7 can rotate and advance inside the pipe. The high-pressure cleaning head 7 is a pre-cleaning tool that pre-cleans and chemically treats the inner wall of the pipe by spraying high-pressure water and chemicals, softening stubborn scale. Solidifying stains creates favorable conditions for subsequent deep cleaning by the PIG cleaning ball 5; the second nozzle 71 and the first nozzle 72 are nozzles with different functions on the high-pressure cleaning head 7. The first nozzle 72 is used to disperse debris in the pipe, and the second nozzle 71, because it is annular and inclined at the tail of the high-pressure cleaning head 7, is inclined at a 45-degree angle to the inner wall of the pipe, so that it can make a spiral motion during spraying, further evenly spraying the agent onto the inner wall. The thrust generated by the agent spraying onto the inner wall can help push the high-pressure cleaning head 7 forward in a spiral shape in the pipe; the water pipe 73 is the pipe connecting the storage tank 3 and the high-pressure cleaning head 7, and is responsible for transporting the chemical agent to the front end of the operation through the high-pressure water pump.
[0019] All electrical components mentioned in this article are connected to an external main controller and 220V AC mains power, and the main controller can be a conventional known device such as a computer that can control it.
[0020] In this invention, the working steps of the device are as follows: First, move the device to the vicinity of the white water pipe to be cleaned using the caster wheels 11, connect the external compressed air source and power supply, and start the system through the main control box 2. Second, open the storage box 4, take out the high-pressure cleaning head 7, insert it into the pipe inlet, and the high-pressure cleaning head 7 draws the cleaning agent from the storage box 3 through the water supply pipe 73, and sprays it at high pressure onto the inner wall of the pipe through the first nozzle 72 and the second nozzle 71. Due to the special design of the second nozzle 71, the high-pressure cleaning head 7 can advance in a spiral shape inside the pipe, softening stubborn contaminants such as fibers, organic slime, and inorganic salt scale. Then, retract the high-pressure cleaning head 7, take out the PIG cleaning ball 5 from the storage box 4, and place it into the pipe. Control the extension and retraction of the support body 61 and the top plate 64 through the adjustment mechanism 6 to expand the PIG cleaning ball 5 to fit the pipe size, and then push it forward in the pipe with compressed air. Use the steel bristles 51 to rub and squeeze the inner wall to thoroughly scrape away the softened stains. Finally, after cleaning is completed, retrieve and clean the components, turn off the device, and complete the entire pipe inner wall cleaning process.
