Description

Technical Field

[0001] The utility model belongs to the field of fluidized bed boiler slag discharge system equipment, in particular to a slag cooler support ring with positioning bolts. Background Art

[0002] As a boiler auxiliary machine, the slag cooler is used to cool the slag after combustion in the boiler so that it can be reused, which is beneficial to environmental protection.

[0003] At present, the slag cooler generally adopts the drum slag cooler. The cooling water flows through the interlayer of the cylinder or the cooling pipe group. The cooling water and the boiler bottom ash indirectly exchange heat in the rolling cylinder to cool the bottom ash. The cooled ash is transported to the outlet of the slag cooler through the slag guide plate in the cylinder.

[0004] like Figure 5 The support ring of the current slag cooler is fixed to the radial plate by bolts by friction. Because there is a 2-3mm gap between the bolts and the bolt mounting holes. As the slag cooler runs, the relative position of the support ring and the radial plate slips, resulting in reduced rotation accuracy of the slag cooler, vibration, increased wear and other defects, which seriously affects the safe and stable operation of the equipment. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model aims to provide a slag cooler support ring with positioning bolts to solve the problems raised in the above-mentioned background technology.

[0006] The utility model is realized by the following technical scheme: a slag cooler support ring with positioning bolts, comprising: a support ring and a radial plate connected to the support ring by a fastener, wherein the fastener is a combination of a positioning bolt and a positioning nut, or a combination of a bolt and a nut;

[0007] One side of the support ring extends toward a side away from the support ring to form a connecting portion, the connecting portion is in contact with the spoke plate, and the connecting portion and the spoke plate bracket are connected together through a plurality of fasteners.

[0008] As a preferred embodiment, a first through hole is formed through the surface of the connection portion, and a second through hole is formed through the surface of the spoke plate, and each of the first through hole and the second through hole constitutes a fixing unit, and a plurality of the fixing units are arranged;

[0009] A fastener composed of a positioning bolt and a positioning nut penetrates 2 to 4 of the fixing units, and the remaining fixing units are fixed by fasteners composed of a bolt and a nut.

[0010] As a preferred embodiment, when the positioning bolt is inserted into the first through hole and the second through hole, the clearance between the positioning bolt and the first through hole and the second through hole is 0.05 mm. This design limits the relative radial displacement between the spoke plate and the support ring, and will not be displaced even if it runs for a long time, thereby ensuring the operation accuracy and service life.

[0011] As a preferred embodiment, when the bolt is inserted into the first through hole and the second through hole, the clearance between the bolt and the first through hole and the second through hole is 2-3 mm.

[0012] As a preferred embodiment, it further comprises a stopper plate, a third through hole is formed through the middle of the stopper plate, and the top of the stopper plate extends upward to form a bendable extension portion.

[0013] As a preferred embodiment, the cross-section of the spoke plate is L-shaped, the bottom of the connecting portion contacts the right side of the spoke plate, the bottom of the connecting portion is supported by the right side of the spoke plate, and the stopper is attached to the left side surface of the spoke plate.

[0014] After adopting the above technical scheme, the beneficial effect of the utility model is: the positioning bolt fixing method is adopted to replace the previous bolt connection method, and this method is reliable in fixing and has a long service life. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figures 1 to 4 The utility model provides a technical solution: a slag cooler support ring 1 with a positioning bolt 4, comprising: a support ring 1 and a radial plate 2 connected to the support ring 1 through a fastener, wherein the fastener is a combination of a positioning bolt 4 and a positioning nut 5, or a combination of a bolt and a nut;

[0024] One side of the support ring 1 extends toward a side away from the support ring 1 to form a connection portion, the connection portion is in contact with the spoke plate 2, and the connection portion and the spoke plate 2 bracket are connected together through a plurality of fasteners.

[0025] As an embodiment of the utility model: a first through hole 6 is formed on the surface of the connecting portion, a second through hole is formed on the surface of the spoke plate 2, each of the first through hole 6 and the second through hole constitutes a fixing unit, and a plurality of the fixing units are arranged;
