The utility model aims to solve the problem of providing the fixing device for the castable of the sanitary belt, which can improve the fixity of the castable of the sanitary belt while ensuring the working efficiency.
The technical scheme includes that the casting material fixing device for the sanitary burning zone comprises a supporting die, wherein the supporting die is in a rectangular plate shape, a first installation groove is formed in the middle of one side of the supporting die in the length direction, a second installation groove is formed in the end portion of the supporting die on two sides of the first installation groove, a connecting portion is formed between the first installation groove and the second installation groove and corresponds to the protrusion of a water wall pipe fin, and the connecting portion is welded with the fin.
Preferably, the first mounting groove is in a semicircular shape which is matched with the outer diameter of the water wall pipe.
Preferably, the second mounting groove is in a 1/4 round shape which is matched with the outer diameter of the water wall pipe.
Preferably, the corresponding connecting parts above and below the formwork are respectively provided with a hook claw, the hook claws are strip-shaped, and the bottom ends of the hook claws are fixedly connected with the formwork.
Preferably, the claw super water wall pipe is obliquely arranged, the length of the claw is 15-17mm, and the width is 8-10mm
Preferably, the formwork is made of 2Cr13 stainless steel with the thickness of 4 mm.
Compared with the prior art, the utility model has the beneficial effects that:
the casting material of the flame retardant belt is fixed on the water-cooled wall by arranging the supporting mould, the supporting mould is welded on the water-cooled wall fin, and one supporting mould is provided with two connecting parts which are welded with the fin, so that the connection strength of the supporting mould and the water-cooled wall pipe is enhanced; meanwhile, the first mounting groove and the second mounting groove are tightly attached to the water wall pipe, so that the contact area is increased, the cooling performance is improved, and the device is not easy to fall off and carbonize during operation; in addition, the upper and lower sides of the formwork are provided with the claw, so that the casting material of the flame retardant belt can be better fixed, and the stability of the casting material is ensured.

FIG. 1 is a schematic top view of the present utility model;
FIG. 2 is a schematic elevational view of the present utility model;
FIG. 3 is a schematic view of the installation of the present utility model;
the drawing is marked: 1. the device comprises a formwork, a first mounting groove, a second mounting groove, a connecting part, a hook claw, a connecting part, a water wall pipe, a fin and a water wall pipe.
Detailed Description
The utility model will be further explained in relation to the drawings of the specification, so as to be better understood by those skilled in the art.
Example 1
As shown in figures 1-3, the flame retardant belt castable fixing device comprises a supporting die 1, wherein the supporting die 1 is rectangular plate-shaped, is prepared from 2Cr13 stainless steel with the thickness of 4mm, and has the advantages of simple structure and excellent strength. The middle part of one side of the formwork 1 along the length direction is provided with a first installation groove 2, the first installation groove 2 is semicircular in shape matched with the outer diameter of the water wall pipe 6, two sides of the first installation groove 2 are positioned at the end part of the formwork 1, the end parts of the formwork 1 are respectively provided with a second installation groove 3, the second installation groove 3 is 1/4 circular in shape matched with the outer diameter of the water wall pipe 6, the first installation groove 2 and the second installation groove 3 correspond to the protrusion of the fins 7 of the water wall pipe 6 to form a connecting part 4, and the connecting part 4 is welded with the fins 7.
In this embodiment, taking a water wall tube 6 with a diameter of 60mm as an example, the length of the formwork 1 is equal to the distance between the central connecting lines of two water wall tubes 6 at two ends of three water wall tubes 6 arranged side by side, and when in operation, the two connecting parts 4 are welded with the fins 7, so that the connection strength of the formwork 1 and the water wall tubes 7 is enhanced; the first mounting groove 2 and the second mounting groove 3 are just attached to the water wall pipe 7, are connected with the surface, improve cooling performance, and ensure that the device is not easy to fall off and carbonize in operation.
The corresponding connecting parts above and below the formwork 1 are respectively provided with a claw 5, the claws 5 are strip-shaped, the bottom ends of the claws 5 are fixedly connected with the formwork 1, the claws 5 are obliquely arranged towards the water wall pipe 6, the lengths of the claws 5 are 15-17mm, and the widths of the claws 5 are 8-10mm. The casting material of the flame retardant belt can be better fixed through the claw 5, and the stability of the casting material is ensured.
