Abstract
The utility model provides an expansion joint for cold quick-witted basin of ring, includes the bellows body, and the bellows body is open structure, and the cross-section of bellows body comprises upper portion rectangle and the semicircular U-shaped that constitutes in lower part, is equipped with the guiding gutter in the bellows body, and the guiding gutter is the rectangle, and the guiding gutter matches with the upper portion rectangle of bellows body. Expansion joint is special to the cold quick-witted basin characteristics of ring and designs, expansion joint upper portion is the opening form, and the lower part is semi-circular structure, adopts welded connection with the cold quick-witted basin of ring during the use. The expansion joint can realize the normal function of the water tank, can also play a compensation role for the water tank when the water tank expands with heat and contracts with cold along with the temperature, eliminates the cold and hot deformation stress of the water tank, and avoids the cracking and water leakage at the welding seam of the water tank. Adopt the utility model discloses can guarantee the normal use of basin, eliminate because of leaking the drawback that influences the cold machine normal work of ring.
Description
Technical Field
The utility model relates to a pipeline compensation part, especially the cold quick-witted for basin expansion joint of ring.
Background
The sintering circular cooler is used for cooling the sintered ore by a blast cooling method, and the temperature of the sintered ore above 700 ℃ is about 150 ℃. The ring cooling machine is provided with a water sealing device to prevent cold air leakage. The water sealing device is provided with a water tank which is filled with water. Because the water tank is heated and expanded when the ring cooling machine works, the water tank is cooled and retracted when the ring cooling machine stops, and the frequent expansion with heat and contraction with cold make the welded junction of the water tank easily cracked, so that the water tank leaks water, the shutdown maintenance is caused, and the normal production rhythm is influenced.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to overcome prior art's drawback, provide a cold quick-witted for basin expansion joint of ring to effectively solve the basin and lead to the drawback of weld opening fracture because of expend with heat and contract with cold.
The purpose of the utility model is realized by the following technical scheme:
the utility model provides an expansion joint for cold quick-witted basin of ring, includes the bellows body, and the bellows body is open-top structure, and the cross-section of bellows body comprises upper portion rectangle and the semicircular U-shaped that constitutes in lower part, is equipped with the guiding gutter in the bellows body, and the guiding gutter is the rectangle, and the guiding gutter matches with the upper portion rectangle of bellows body.
The expansion joint for the water tank of the circular cooler is characterized in that the end part of the diversion trench corresponding to the medium flowing direction is provided with a wear-resistant strip.
The expansion joint for the water tank of the ring cooling machine is characterized in that end connectors are arranged at two ends of the corrugated pipe body, each end connector comprises an upper end connector rectangular body and a lower end connector semicircular body, the axial size of each end connector lower semicircular body is smaller than that of each end connector rectangular body, and a sealing plate is arranged at the end part of each end connector semicircular body.
The expansion joint for the water tank of the ring cooling machine has the advantages that the wave crest of the corrugated pipe body is not less than three sections.
Expansion joint is special to the cold quick-witted basin characteristics of ring and designs, expansion joint upper portion is open-ended rectangle form, and the lower part is semi-circular structure, adopts welded connection with the cold quick-witted basin of ring during the use. The expansion joint can realize the normal function of the water tank, can also play a compensation role for the water tank when the water tank expands with heat and contracts with cold along with the temperature, eliminates the cold and hot deformation stress of the water tank, and avoids the cracking and water leakage at the welding seam of the water tank. Adopt the utility model discloses can guarantee the normal use of basin, eliminate because of leaking the drawback that influences the cold machine normal work of ring.
Drawings
The present invention will be further explained with reference to the accompanying drawings.
Fig. 1 is a schematic structural diagram of the present invention;
FIG. 2 is a left side view of FIG. 1;
fig. 3 is a sectional view a-a of fig. 1.
The reference numbers in the figures are: 1. the corrugated pipe comprises a corrugated pipe body, 2 parts of a diversion trench, 3 parts of a sealing plate, 4 parts of an end connector, 4-1 parts of an end connector rectangular body, 4-2 parts of an end connector semicircular body, and 5 parts of a wear-resistant strip.
Detailed Description
Referring to fig. 1-3, the present invention includes a bellows body 1, which is an upper open structure, and the cross section of the bellows body is formed by an upper rectangle and a lower semicircle to form a U-shape. The corrugated pipe body is characterized in that end joints 4 are symmetrically welded at two ends of the corrugated pipe body, each end joint is composed of an upper end joint rectangular body 4-1 and a lower end joint semicircular body 4-2, the axial size of the lower end joint semicircular body is smaller than that of the end joint rectangular body, and seal plates 3 are welded at the end parts of the end joint semicircular bodies. A diversion trench 2 is arranged in the corrugated pipe body, the diversion trench is a rectangular trench, the diversion trench is matched with the upper rectangle of the corrugated pipe body, and the inlet end of the diversion trench is welded with the end connector rectangular body. In order to avoid excessive washing of the diversion trench by flowing media and prolong the service life of the diversion trench, the end part of the diversion trench corresponding to the flowing direction of the media is provided with a wear-resisting strip 5.
The corrugated pipe body is subjected to solid solution treatment after being formed so as to improve the stress corrosion resistance and prevent the stress corrosion in subsequent use.
The utility model discloses adopt welded connection with cold quick-witted basin of ring during the use. The expansion joint has the advantages that the expansion joint has the expansion function, so that the cold and hot deformation stress of the water tank is eliminated, and the water tank is prevented from cracking and leaking water.
