Rotary quantitative ash collection device capable of blowing back fly ash

Abstract

The invention relates to boiler ash-collecting equipment and especially relates to a rotary type rationed ash-collecting device for reversing blowing ash. The rotary type rationed ash-collecting device comprises a valve body, a valve core, an upper end flue, a lower end flue and an ash-collecting pit, wherein the valve core is in rotary connection in the valve body through bearings at the two ends of the valve core; the upper end flue is arranged above the valve core; the lower end flue is arranged under the valve core; the ash-collecting pit is arranged on the valve core; a motor shaft is connected with one end of the valve core; the depth of the ash-collecting pit is more than the radius of the valve core and less than the diameter of the valve core; arc slots are arranged on the valve core on the two sides of the ash-collecting pit, so that more accurate rationed ash-collecting work can be realized; the problems of deposited ash cementation can be effectively solved; the deposited ash in the ash-collecting flue can be reversely blown and the excessive ash can be discharged from the device; the online testing efficiency is increased; the maintenance period is prolonged.

Description

technical field [0001] The invention relates to boiler ash collection equipment, in particular to a rotary quantitative ash collection device capable of blowing back fly ash. Background technique [0002] At present, the carbon content of boiler fly ash is an important indicator to reflect the combustion efficiency of coal-fired boilers in thermal power plants. link is especially important. The advantage of on-line detection is reflected in real-time performance. The currently used ash collection devices generally have problems such as unquantifiable and unstable ash collection, easy ash powder bonding, and blockage of ash collection channels, which seriously affect the online detection of carbon content in fly ash. The practical significance, and increase the cost of maintenance. Contents of the invention [0003] The technical problem to be solved by the present invention is: in order to solve the problems existing in the existing ash collection device, such as unstabl...
