Description

Technical Field

[0001] The utility model relates to an online cleaning and maintenance system for a chemical furnace, belonging to the technical field of chemical cleaning. Background Art

[0002] Chemical furnaces, as key equipment in chemical production, undertake multiple important functions such as heating, reaction, and evaporation, which have a direct impact on the quality of chemical products and production efficiency. However, with the long-term operation of chemical furnaces, various dirt and sediments such as polymers, coke, oil dust, scale, sediments, and corrosion products will inevitably accumulate inside them. These dirt not only reduces the thermal efficiency of the chemical furnace and increases energy consumption, but may also cause safety hazards and affect the stability and safety of chemical production.

[0003] According to Chinese invention patent CN111018096B, an aeration system maintenance device and method with two-dimensional dissolved oxygen detection and online cleaning functions are disclosed. A vehicle is installed on or underwater in a currently commonly used aeration tank. The vehicle is equipped with online dissolved oxygen detection equipment, ultrasonic cleaning equipment, and underwater ranging equipment. Under normal production (aeration) conditions, a two-dimensional dissolved oxygen distribution map and aerator depth point map can be drawn. When the aerator is clogged, the ultrasonic cleaning device performs online cleaning. The device can collect the dissolved oxygen distribution of the aeration tank in real time. The dissolved oxygen distribution allows operators to obtain real-time information on the biochemical reactions in the aeration tank and accurately locate damage to the aeration pipes and aerators. When the aeration head is clogged, the aerator can be ultrasonically cleaned online without draining the aeration tank. The cleaning time is short and no drugs or manual operation are required. Furthermore, the system can be linked with the aeration control system to achieve precise aeration.

[0004] The existing technology integrates a variety of high-tech equipment such as online dissolved oxygen detection equipment, ultrasonic cleaning equipment and underwater ranging equipment, which may lead to higher overall complexity of the system and corresponding increases in manufacturing costs, installation costs and subsequent maintenance costs.

[0065] Working process or working principle:

[0066] The motor is powered on and started, and the rotational torque drives the chain sprocket assembly 4 through its output end to start running; the power is transmitted to the rotating water pipe 6 through the chain sprocket assembly 4; the chain tensioning device 5 can adjust the tightness of the chain as needed, and as the chain sprocket assembly 4 runs, the rotating water pipe 6 starts to rotate; the rotating water pipe 6 passes through the support plate assembly I 21 and the support plate assembly II 22 of the support frame group 2, and is firmly connected by the support rod 23, which can withstand the rotational force of the high-pressure water pipe and the impact force during the cleaning process;

[0067] When the rotating water pipe 6 rotates, the high-pressure cleaning liquid is evenly and densely sprayed onto the inner wall of the chemical tank 1 to be cleaned through the nozzle 73 installed on the inverted Y-shaped spray pipe 7, achieving all-round and efficient cleaning of the inner wall of the tank;

[0068] At the connection between the rotating water pipe 6 and the inverted Y-shaped spray pipe 7, a square mounting plate is used in conjunction with an O-ring 72 to ensure the sealing of the connection. The dust ring 27 and cover plate 28 effectively prevent the ingress of dust and impurities, protecting the cleanliness and normal operation of the internal structure. The rotating support seat I 212 and the rotating support seat II 222 are connected to the rotating water pipe 6 through a tightening bolt sleeve 41, which facilitates installation and disassembly and also enhances the stability of the structure.

[0069] The bottom of the driving device 31 is provided with a base 33, and is provided with bolt mounting slots I 331 and II 332 of different lengths, so that the driving device 31 can be flexibly adjusted according to the actual installation environment. When installing the triangular mounting plate 32, it is convenient to install the bottom bolts. The fixing notch 231 at the top of the support rod 23 is also designed to facilitate quick connection and fixation with other components.

[0070] When the inner wall of the chemical tank 1 to be cleaned is cleaned, the driving device 31 is turned off, and the rotation and spraying of the rotating water pipe 6 are stopped. At this time, the entire cleaning system is in a standby state, waiting for the next cleaning task.
