The technical scheme that the utility model provides is: a kind of combustion-supporting and energy-saving control system, the straight-line motion mechanism that it is made up of screw and sliding thick stick assembly, oppositely alternating current generator, speed regualtion of AC motor device, the transmission controlling mechanism of forming near switch module of control are formed, and are fixed on the frame to be fixed on stirring shaft on the linear bearing slide block and band.
Above-mentioned stirring shaft part is characterized in that structural pipe wall is made up of fire-resistant nonmetallic materials outer lining, fire-resistant non-metallic fillers layer and metal tube, its thermal conductivity factor have only metal tube 1/20th in, effectively reduce the flow that uses cooling circulating water; The metal tube of stirring shaft is embedded in thermal coefficient of expansion and forms the chilled(cooling) water return (CWR) greater than the dividing plate that metal tube, width equate with the metal tube interior diameter; The stirring shaft outer wall is the equidistant stirring teeth of arranging of fire-resistant nonmetallic materials, the spacing of stirring tooth is the 10-30 centimetre, stir tooth angled and alternately arrangement with the reciprocating vertical plane of stirring shaft, reciprocating in the vertical direction of advancing with fire grate, stir the solid fuel of burning, reach combustion-supporting effect.
The straight-line motion mechanism that above-mentioned reciprocator part is made up of screw, linear bearing, sliding thick stick assembly, the alternating current generator of band reversing controller, speed regualtion of AC motor device, near switch module and transmission component composition, controlled reciprocating stroke and speed.
Above-mentioned rack section is used for fixing above-mentioned motion and Control Component, and frame can turn to bracing frame to pass through the back shaft and the holding screw of frame by the spill of fireplace one end, can select to fix on the ground or be fixed on the boiler wall.
The beneficial effects of the utility model are, thereby reduce the heat output of stirring shaft in stove by the nonmetallic materials flame retardant coating quantity of circulating water are effectively reduced, and have eliminated operational failure risk and boiler safety hidden danger that high pressure, high temperature circulation water are brought; By the embedding dividing plate of stirring shaft inner wall of metal tube, make the circulating water loop structure very simple and increased the bending strength of stirring shaft; Spiral reciprocator, travel speed control automatically make the reciprocating action of stirring shaft more accurately steady, and have increased the motion control free degree of stirring shaft, enable to control the stirring tooth and select best energy-conservation motor pattern; Spill can turn to bracing frame to select the fixed position flexibly according to the equipment mounting condition, has improved the equipment installation flexibility.
