Abstract

The utility model relates to a cantilever type poking machine, is composed of a reciprocating shaft (9), a ram (6), an upper and lower guide pulleys, rockers, etc. A poking bar (10) is arranged on the reciprocating shaft (9). The lower part of the poking bar is transversally provided with a baffle (18) with penetrability. The utility model after trial can be integrally installed and is independent equipment which only needs a fire door arranged at the primary combustion zone of the boiler. The utility model improves the combustion physics condition of the coal bed at the primary combustion zone of the boiler, causes the coal bed to burn sufficiently and can be applied all chain grate boiler. The carbon content of the ash falls to 4-14%. The coal consumption drops down 20-30% compared with the origin.

Description

Cantilever type poking machine

The utility model relates to a kind of equipment of stirring coal seam in the boiler.

For improving the combustion physics condition in the chain grate boiler, name is called " chain grate boiler mechanical poking device ", and (patent No.: utility model patent 90212992.9) provides a solution, its technical scheme is that back and forth axle is installed on fire grate, back and forth designing the bar that pokes fire on the axle, in actual motion, find, this scheme is only applicable to the chain grate boiler of two relative observation doors, and to having only the boiler of an observation door, back and forth axle can not cross and mistake, thereby can not install and use.

As long as to be design a kind of an observation door with regard to the spendable cantilevered machine that pokes fire in the boiler primary zone for the purpose of this utility model, make the bulk coke in boiler primary zone become fragment, improve the coal bed ventilation condition and allow the coal seam fully burn, reduce ash content carbon, improve the boiler output and the thermal efficiency.

The utility model adopts following structure to finish its inventive concept: the reciprocal axle of cantilevered (9) is enclosed within on the ram (6), ram (6) is installed on the lower tumbler (7), and it is reciprocating that eccentric wheel (2) drives reciprocal spool (9) by movable slider (4), fork (3).

The contrast accompanying drawing is described in detail below:

Fig. 1: the poke fire overall structure schematic diagram of machine of cantilevered.

Fig. 2: the structural representation of fork.

Fig. 3: the structural representation of guide wheel and fixed axis.

Fig. 4: the generalized section of the reciprocal axle and the bar that pokes fire.

The reciprocal axle of cantilevered (9) is installed in parallel on the grate surface, back and forth axle (9) is a steel pipe, a dividing plate (14) is installed in steel pipe, the steel pipe inner chamber is divided into two parts, reciprocating on grate surface, driven with fork (3) ram (6) by reduction box, eccentric wheel (2) by motor. Back and forth an end cover of axle (9) has ram (6), ram (6) is connected with screw with reciprocal axle (9), upper and lower surface at ram (6) has respectively upper block (8), lower tumbler (7), upper and lower guide wheel is enclosed within on the fixed axis (15), and a ball bearing (16) is respectively installed at upper lower tumbler two ends. Because back and forth axle (9) is worked in the boiler primary zone, the temperature height, not yielding for guaranteeing reciprocal axle (9) and the bar that pokes fire (10), except taking heat proof material, also adopt forced water to cool off the normal operation that guarantees reciprocal axle and poke fire bar, with normal temperature soft water by water pump from an effluent of steel pipe inner chamber through the bar that pokes fire (10), the opposite side that flows through again the steel pipe inner chamber is got back to delivery port. In the reciprocal stove outside of axle (9) electric contact thermometer is installed, when water pump hinders when quitting work for some reason, the surplus water vapor of steel pipe internal cause, when temperature was raised to 100 ℃, electric contact thermometer just action was reported to the police, and safety radiator is opened, and guarantees that operation normally carries out. Poke fire and vertically be provided with a dividing plate (17) in the bar (10), to have water to flow through in the bar that guarantees to poke fire, prevent vapour lock, be horizontally installed with in addition a dividing plate (18) with penetration in the bar bottom that pokes fire, dividing plate (18) forms a vaporization chamber with the top, bar bottom that pokes fire, when the water of vaporization chamber heated up vaporization, steam was to spray-hole and dividing plate spray Penetrate, when vaporization chamber pressure was lower than water pump pressure, the water in the bar that pokes fire further improved burning condition in the stove just to the vaporization chamber seepage. Fixed axis (15) is installed on the bearing block (11), bearing block is fixed on the frame (1), have sliding tray at fork (3) middle part and bottom, the moving slide block (4) that links to each other with eccentric wheel is installed in the sliding tray, sliding block (5) is installed in the sliding tray of fork bottom, and sliding block (5) is fixed on the frame (1), and upper lower tumbler adds protective cover (12), after back and forth axle installs, install closing door (13) additional.

The utility model is through on probation, not only alleviated operator's labour intensity, and improved exerting oneself and the thermal efficiency of boiler, face arch outlet cigarette stripping temperature improves more than 200 degree under equal consumption coal, the coal consumption 20-30% that descended than originally, ash content carbon drops to 6-14.2% by original 16-28%, has obtained significant energy-saving effect. In addition, because the utility model can be produced by batch, as long as in the boiler primary zone observation door is arranged, therefore just at the scene integral installation, adapts to all chain grate boilers and uses.

Accompanying drawing has been described an embodiment of the present utility model:

The bar that pokes fire evenly distributes, and back and forth the distance between axle (9) and the grate surface is 20-30mm, and eccentric rotating speed is 5 rev/mins, and pump capacity is decided on the boiler size.
