Problems solved by technology
Due to the dusty pattern, the wire brush head is difficult to fit the inner wall of the crucible, etc., the crucible, especially the wall surface, often has residual ash, which affects the measurement results; in addition, the clamping mechanism and the special shape of the crucible matched with it and an additional set of brush heads are required. Rotating power devices, etc. make the structure and system complex, and the processing and operation costs increase

Embodiment Construction
[0024] The present invention will be described in detail below with reference to the accompanying drawings and examples.
[0025] This embodiment provides a rotary lifting ash cleaning mechanism for a crucible used for on-line analysis of combustible content by weight loss method. The mechanism has a simple structure and reliable operation, and the elastic scraper effectively removes residual ash on the crucible wall to ensure the accuracy of measurement results.
[0026] like figure 1 As shown, the rotary lifting and cleaning mechanism includes: a rotary lifting mechanism and a cleaning head; the rotary lifting mechanism uses a motor to drive a screw pair or a cylinder to complete the up and down movement of the lifting shaft; it uses a spiral guide sleeve, a guide slide pin, a spring and thrust bearings convert the linear movement of the lifting shaft into the forward and reverse rotation of the crucible; the cleaning head adopts the cleaning head with the elastic scraper th...

The invention provides a rotary lifting deashing mechanism. The whole rotary lifting deashing mechanism is simple in structure and reliable in working, residual ash on the wall surface of a crucible is effectively removed through an elastic doctor blade, and the accuracy of the measurement result is ensured. The rotary lifting deashing mechanism comprises a deashing head and a rotary lifting mechanism of which the top is provided with a crucible tray, wherein lifting motion and rotary motion of the rotary lifting mechanism adopt the same power unit, the rotary lifting mechanism can conveniently cooperate with an electric or pneumatic linear traveling mechanism to automatically complete the deashing process, and a rotary power device does not need to be additionally arranged. The deashing head effectively breaks heavily-hardened ash samples through rolling and cutting, accordingly, ash is effectively removed, and the accuracy of the measurement result is ensured.
Description
technical field [0001] The invention relates to a dust cleaning mechanism, in particular to a rotary lifting dust cleaning mechanism. Background technique [0002] The traditional method of combustible content detection by weight loss method is an off-line laboratory analysis method, which requires manual operation. Due to its complicated operation and long measurement period, it cannot be continuously measured on-line. In order to improve the thermal efficiency of combustion equipment such as boilers, an online detection device that can reflect the content of solid combustibles in combustion products in real time is derived, that is, the online analysis system for combustibles content by weight loss method, so that the combustion conditions can be adjusted and optimized in time according to the detection results to achieve energy saving. purpose of emission reduction. [0003] In order to ensure the normal operation of the online analysis system, a reliable ash removal de...
