Detailed Description
As shown in figure 1, the invention provides a cross-section structure diagram of a membrane type wall tube panel ash removal device, which is characterized in that a square steel plate with the thickness of about 16mm is connected to the center of a membrane type wall tube panel B on the inner side (left side in the figure) of a furnace wall A to serve as a stress plate 1, a supporting steel tube 2 with the length of about 150mm phi 76mm multiplied by 6mm is welded on the stress plate 1 to serve as a fixed support of a force guide rod 3, one end of the force guide rod 3 is movably inserted into the supporting steel tube 2, and the other end extends out of the furnace wall A;
a cover box 5 is arranged on the outer side (right side in the figure) of a hole for the force guide rod 3 to pass through on the furnace wall A, a section of phi 108mm multiplied by 6mm inner steel pipe 6 is arranged in the cover box 5 (left side in the figure), a section of phi 108 multiplied by 6 outer steel pipe 7 is also arranged on the outer side (right side in the figure) of the cover box 5, and the inner steel pipe 6 and the outer steel pipe 7 are sleeved on the radial outer side of the force guide rod 3;
the outer end (right end in the figure) of the outer steel pipe 7 is fixed with a flange 10 for butt joint with a sealing sleeve, the sealing sleeve comprises two phi 108mm multiplied by 6mm sleeves 13 and a silicone rubber glass varnished cloth 15 connected between the two sleeves 13, one end of one sleeve 13 is fixed with a flange cover 12, and the flange cover 12 and the flange 10 are in opposite sealing connection by using bolts;
a hole with the diameter of phi 52mm is formed in the flange cover 12, a force guide rod 3 with the diameter of phi 50mm penetrates out of the flange cover 12 and then penetrates out of the sealing sleeve, an annular sealing plate 14 is fixed on the outer side of the sleeve 13 close to the outer side, the annular sealing plate 14 can be in sealing connection with the force guide rod 3 through welding, so that flue gas in a furnace cannot leak, and when the force guide rod 3 moves left and right with the annular sealing plate 14, the soft silicone rubber glass varnished cloth 15 can allow the annular sealing plate 14 to move;
a retainer ring 8 is fixed on the force guide rod 3, the retainer ring 8 is positioned in the outer steel pipe 7 and is about 200mm away from the flange cover 12, a compression spring 9 is arranged on the force guide rod 3 between the retainer ring 8 and the flange cover 12, and the force guide rod 3 is always propped against the stress plate 1 of the film wall pipe screen B by utilizing the tension of the compression spring 9.
Because the inside of the general boiler is high-temperature flue gas, the high-temperature flue gas enters the cover box 5 and the inner side steel pipe 6 through the holes formed in the furnace wall A during operation, although the part is non-flowing flue gas, after the device is filled, the temperature is not very high, but the temperature still has about 60 ℃, the solution is that the cover box 5 is filled with casting materials 4 except the inner side sleeve 6, and a soft aluminum silicate fiber pipe shell 11 is sleeved between the inner side sleeve 6 and the force guide rod 3, so that the leakage of the flue gas is effectively prevented; the force guide rod 3 is arranged in the inner sleeve 6 and is coated with the soft aluminum silicate fiber tube shell 11, so that the normal operation of the force guide rod is not affected and the force guide rod is protected.
When ash removal is needed, only one striking force is given to the outer end part of the force guide rod 3, the inner end of the force guide rod 3 can strike the stress plate 1 of the film type wall tube panel B, so that the film type wall tube panel B can generate strong vibration, deposited ash on the film type wall tube panel B can be cleaned, and the resilience force of the force guide rod 3 in the opposite direction is absorbed by the compression spring 9 after being struck, so that the silicon rubber glass paint cloth 15 outside the flange cover 12 is protected from being torn.
In the invention, the end part of the force guide rod 3 can be matched and connected with an electric vibrating device so as to realize automatic operation.
When the invention needs to be maintained, the whole force guide rod 3 can be pulled out for replacement or maintenance only by loosening the bolts for connecting the flange 10 and the flange cover 12.
