Abstract
The present invention relates to an automatic blockage dredging apparatus of a cold slag machine slag feeding pipe, wherein a reservation hole is arranged on the slag feeding pipe arranged between the boiler slag discharge port and the cold slag machine slag inlet, and is connected with the spraying pipe of an air gun. The automatic blockage dredging apparatus has advantages of safety, reliability, no requirement of manual operation, no maintenance personnel safety problem, rapidness, convenience, short time consuming of the blockage dredging work, maintaining of continuity of the boiler slag discharge process, and no influence on the normal equipment operation.
Description
Technical field
The present invention relates to a kind of lag cooler, be specifically related to a kind of lag cooler slag feed pipe automatic sparse block apparatus.
Background technology
The supporting lag cooler slag feed pipe of fluidized-bed combustion boiler often can block, and the slag fibre of disclosing adopted at present manually discloses slag, needs the at substantial time, affect the normal operation of equipment when dredging stifled, does not also reach ideal effect when stifled slag is serious; The weight adopted mode of knocking is dredged stifled, not only takes time and effort, and does not have positive effect, also has warm sludge ejection to scald the danger of maintainer simultaneously.
Summary of the invention
For solving the problem, the invention reside in and provide a kind of lag cooler slag feed pipe automatic sparse block apparatus, it adopts the mode of Automatic Control, and without the need to manual operation, what can complete rapidly blocking region dredges stifled work simultaneously, has ensured the normal operation of equipment.
The invention provides following technical scheme: a kind of lag cooler slag feed pipe automatic sparse block apparatus, the slag feed pipe arranged between boiler slag removal mouth and lag cooler slag inlet is provided with preformed hole, and described preformed hole is connected with the jet pipe of air bubble;
Described air bubble is connected with boiler rigid mount by flexible suspension.
Accompanying drawing explanation
Fig. 1 is the embodiment of the present invention one structural representation
Fig. 2 is the embodiment of the present invention two structural representation
1-lag cooler slag feed pipe in figure, 2-jet pipe, 3-flexible suspension, 4-boiler rigid mount, 5-suspension ring, 6-big gun body, 7-intake valve, 8-insulating tube.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, elaboration detailed is further done to the present invention, not limiting the scope of the invention.
Embodiment one
As shown in Figure 1, a kind of lag cooler slag feed pipe automatic sparse block apparatus, comprise the lag cooler slag feed pipe 1 arranged between boiler slag removal mouth and lag cooler slag inlet, described lag cooler slag feed pipe 1 is provided with preformed hole, described preformed hole is connected with the jet pipe 2 of air bubble, described air bubble is connected with the suspension ring 5 of boiler rigid mount 4 by flexible suspension 3, and described flexible suspension 3 can prevent from drawing bad air bubble during boiler expansion.
Embodiment two
As shown in Figure 2, a kind of lag cooler slag feed pipe automatic sparse block apparatus, comprise the lag cooler slag feed pipe 1 arranged between boiler slag removal mouth and lag cooler slag inlet, described lag cooler slag feed pipe 1 is provided with preformed hole, described preformed hole is connected with the jet pipe 2 of air bubble, described lag cooler slag feed pipe 1 overcoat has the insulating tube 8 preventing air bubble from directly contacting with high temperature lag cooler slag feed pipe, and described air bubble big gun body 6 is fixed on insulating tube 8.
Method of operating of the present invention is flexible, comprise automatically controlled single or blow out in groups, the timing automatic control method such as to blow out.During operation, first open the intake valve 7 controlling air bubble source of the gas, gas is made automatically to enter big gun body 6, when need blow out, controller is to air bubble reversal valve pulse signal, and air bubble sprays powerful impact air-flow by jet pipe 2 subsequently, overcome the static friction of slag, the slag in air bubble slag feed pipe is made to recover gravity flowing, and air bubble automatic inflating, for again dredging stifled preparing.
Claims (2)
1. a lag cooler slag feed pipe automatic sparse block apparatus, is characterized in that, the slag feed pipe arranged between boiler slag removal mouth and lag cooler slag inlet is provided with preformed hole, and described preformed hole is connected with the jet pipe of air bubble.
2. lag cooler slag feed pipe automatic sparse block apparatus according to claim 1, it is characterized in that, described air bubble is connected with boiler rigid mount by flexible suspension.
