Description

Technical Field

[0001] The utility model relates to the technical field of boiler cleaning equipment, in particular to a boiler hydraulic ash cleaning metal hose winding mechanism. Background Art

[0002] Traditional boiler cleaning equipment includes steam, vibration, and shock wave systems. Although hydraulic cleaning systems developed relatively recently, they have proven to be a highly effective boiler cleaning method due to their simple structure, easy operation and maintenance, safety and reliability, low energy consumption, and significant cleaning effectiveness. As an alternative or supplement to traditional cleaning methods, hydraulic cleaning is gaining popularity among a growing number of boiler operators.

[0003] Due to the characteristics of the hydraulic cleaning system, the metal hoses of existing hydraulic cleaning equipment all adopt the equal radius coiling method. The advantages are: (1) the metal hose coiling is stable; (2) the control is simple, and the rising and falling speeds of the nozzle can be simply matched with the rotation speed of the turntable. However, the equal radius coiling method also has disadvantages: the equal radius coiling method will cause the turntable structure to become bulky. In order to meet the boiler height requirements, the length of the metal hose is usually designed to be between 20 and 25 meters. The equal radius coiling method will make it impossible to make the turntable structure smaller, and the overall size of the device is large. Due to the limited site conditions of the old boiler, the technical transformation plan of adding a hydraulic cleaning system will also be restricted. Utility Model Content

[0040] Furthermore, as a preferred embodiment, the motor 2 is preferably a variable frequency motor.

[0041] Furthermore, as a preferred embodiment, the detection system includes: a distance detection sensor 7, a hose lower limit sensor 8, a hose upper limit sensor 9, and a distance detection device 10.

[0047] Furthermore, as a preferred embodiment, a rotating hole is provided in the middle of the turntable 12, and both ends of a connecting shaft pass through the rotating hole and are connected to the turntable 12. A connecting hole is opened in the middle of the distance detection device 10, and the connecting shaft passes through the connecting hole and is connected to the distance detection device 10.

[0048] Further, as a preferred embodiment, a connecting shaft connects the turntable 12 and the distance detecting device 10 .

During this process, the winding radius of the hoses 3 staggered on the turntable 12 will continuously change, and the guide wheel assembly 5 is used to provide support for the hose 3 so that the hose 3 can be smoothly released from the turntable 12, thereby allowing the nozzle 5 to descend smoothly; during the ascent of the nozzle 5, the motor 2 is first used to drive the turntable 12 to rotate clockwise, and then the nozzle 5 and the hose 3 are driven to rise.
