The following detailed description of embodiments of the utility model refers to the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating the present invention, are given by way of illustration and explanation only, not limitation.
In the present invention, the term "outside" refers to an orientation relatively far from the inside of the kiln, and the term "inside" refers to an orientation relatively close to the inside of the kiln.
The utility model provides a fire baffle plate of a glass kiln, wherein the fire baffle plate can be attached to the outer surface of a nozzle brick of the glass kiln, the fire baffle plate comprises a body plate 1, a nozzle hole 2 corresponding to a through hole of the nozzle brick is arranged on the body plate 1, and the nozzle hole 2 can accommodate a nozzle and is partially inserted from the outer part of the body plate 1.
The glass kiln is provided with nozzle bricks, through holes are formed on the nozzle bricks, and fuel is sprayed into the nozzle bricks through the nozzle assemblies.
The fire shield plate of the glass kiln of the scheme is used for being arranged on the outer surface of a nozzle brick and comprises a body plate 1, wherein a nozzle hole 2 (shown in figures 1-3) is formed on the body plate 1, the nozzle hole 2 is aligned with a through hole of the nozzle brick, and the nozzle hole 2 can allow a nozzle to be partially inserted from the outer part of the body plate 1 so as to allow the nozzle to inject fuel into the glass kiln through the nozzle hole and the through hole.
In this scheme, the fire board makes nozzle and nozzle brick keep the interval each other, avoids the higher nozzle brick direct contact of nozzle and temperature, reduces the inside flame of kiln and stretches to nozzle department through the through-hole on the nozzle brick to can protect the nozzle, prolong the life of nozzle.
Alternatively, the nozzle bore 2 comprises a first section on the outside, which has an inner diameter larger than the inner diameter of a second section on the inside, which first section is able to accommodate the nozzle insertion. As shown in fig. 3, the nozzle bore mainly comprises two sections, the inner diameter of the first section located on the outside is approximately the inner diameter of the second section located on the inside, and the two sections are transited by a step surface, which allows the nozzle to be inserted into the first section, and the nozzle can be stopped by the step surface to position the nozzle. Wherein the inner diameter of the first section can be matched with the outer diameter of the nozzle, so that the nozzle is tightly matched with the first side surface of the nozzle hole, and leakage is avoided.
Further, the inner diameter of the second section is the same as the inner diameter of the through hole. The inner diameter of the second section is set to be the same as that of the through hole of the nozzle brick, and the second section and the through hole are coaxially butted with each other to form a round hole with smooth transition, so that the fuel sprayed by the nozzle can smoothly flow into and pass through the nozzle hole 2 and the through hole on the nozzle brick.
In addition, the inner side surface of the body plate 1 is provided with a protruding ring 4 surrounding the nozzle hole 2, which protruding ring 4 can be embedded in a nozzle brick. The inside surface of the body plate 1, i.e., the surface facing and attached to the nozzle brick, is provided with a protrusion ring 4, which protrudes with respect to the body plate 1 and surrounds the nozzle hole 2, and accordingly, a recess is formed on the outer surface of the nozzle brick to allow the protrusion ring 4 to be embedded, improving the coupling strength between the fire shield and the nozzle brick.
Further, the projecting ring 4 is concentric and of equal diameter with the inner portion of the nozzle hole 2. As shown in fig. 3, the inner portion of the nozzle hole 2 mainly refers to an outlet end portion in the fuel flow direction, and the projecting ring 4 is concentric and of equal diameter with the outlet end portion of the nozzle hole 2, and the projecting ring 4 forms a hole for further smooth extension of the nozzle hole 2.
In addition, the inner side surface of the body plate 1 is provided with positioning ribs 5 extending in two directions perpendicular to each other, and the positioning ribs 5 can be embedded in the nozzle brick. The positioning ribs 5 extend in two mutually perpendicular directions and the positioning ribs 5 are embedded in the nozzle brick so that the fire shield plate cannot rotate relative to the nozzle brick around the central axis of the nozzle bore 2, achieving a relative positioning of the fire shield plate and the nozzle brick.
In addition, the outer side surface of the body plate 1 is provided with a plurality of protruding heat dissipation ribs 3. As shown in fig. 1 and 3, the outer surface of the body plate 1 is provided with a plurality of parallel heat dissipation ribs 3, and the heat dissipation ribs 3 increase the heat dissipation surface of the fire damper at the outer side, so that heat in the fire damper can be dissipated more rapidly, the temperature of the fire damper is reduced, and the nozzle in direct contact with the fire damper is protected.
Further, the top surface of the heat dissipation rib 3 is an arc-shaped surface. As shown in fig. 3, the heat dissipating ribs 3 have a circular arc-shaped top surface, which can further increase the surface area of the heat dissipating ribs 3, improving the heat dissipating capability, to dissipate heat more quickly. In other embodiments, other protruding or recessed structures may be disposed on the heat dissipation rib 3 to increase the surface area, i.e. increase the heat dissipation area, by increasing the complexity of the shape.
Wherein the fire damper is made of heat resistant steel. Based on the performance, the heat-resistant steel includes two types, namely, oxidation-resistant steel and heat-resistant steel, or the heat-resistant steel can be divided into austenite heat-resistant steel, martensite heat-resistant steel, ferrite heat-resistant steel, pearlite heat-resistant steel and the like by a crystal structure. The fire baffle made of heat-resistant steel can prevent the fire baffle from deforming or even melting at high temperature, and can increase the heat conductivity of the fire baffle, so that the heat in the fire baffle can be dissipated outwards more quickly.
The fire baffle can be integrally formed by casting, powder metallurgy and other modes, namely the heat dissipation rib 3, the protruding ring 4 and the positioning rib 5 are integrally connected with the body plate 1.
