Furnace Hydro Sootblower

Abstract

The invention relates to the technical field of hearth cleaning devices, in particular to a hydraulic soot blower of a hearth. The hydraulic soot blower comprises an installation plate, a taper hopper, a horizontal transmission assembly, a vertical transmission assembly and a water gun. The taper hopper protruding frontward is fixedly installed in the middle of the installation plate, a front fixing frame is fixedly installed in the middle of the taper hopper, and a front universal joint is installed on the front fixing frame. The water gun comprises a spraying pipe and a spraying head, the front end of the spraying pipe is connected with the rear end of the spraying head, the spraying head is installed on the front universal joint and located on the front side of the taper hopper, and the spraying pipe is installed on a rear universal joint. The hydraulic soot blower is reasonable and compact in structure and convenient to use. According to the principle of a modern numerically-controlled machine tool, a servo motor and a ball screw pair are adopted for enabling the spraying pipe to move vertically or horizontally, synchronous rotation of an upper screw and a lower screw is achieved through a synchronous transmission shaft, the phenomenon that the upper end and the lower end of a vertical shaft do not move synchronously is avoided, and therefore the spraying pipe is prevented from deflecting, the control accuracy is higher, transmission is more stable, abrasion is small, and the swing accuracy of the spraying pipe is guaranteed.

Description

technical field [0001] The invention relates to the technical field of furnace cleaning devices for large coal-fired power generation boilers, and relates to a furnace hydraulic sootblower. Background technique [0002] The furnace of the boiler is easy to coke during the working process. Power plants usually use steam soot blowers for cleaning. The steam soot blowers are arranged on the water wall of the boiler. Only one radius can be blown with a steam sootblower 1.5m to 2m and there is a gap between one circle and the other, forming a cleaning blind area. At the same time, due to the disturbance of high-pressure steam to the combustion, the steam soot blower cannot be close to the burner, and there are also a large number of blind areas that need to be cleaned next to the burner. Therefore, the traditional steam It is difficult for soot blowers to clean the coking areas. In addition, the furnace steam soot blowers have high mechanical failures, and the large numb...
