Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of glass production, in particular to a modular arch form for glass furnace masonry. BACKGROUND

[0002] China is a big country of glass production, in order to ensure the glass production, every year will demolish a lot of service life of glass furnace, also will build a lot of different specifications, different types of furnace. Glass furnace is the heart of glass industry production, is the key thermal equipment in engineering construction; and the big arch is a very important part of the structure of the furnace.

[0003] The arch form is an essential tool for masonry of the big arch of the furnace, which provides an arch-shaped support for the masonry of the big arch bricks. The big arch has strict requirements for the gap between adjacent rows and the brick joints between the same row of bricks during the masonry process. The poor precision of the arch form will result in the failure to guarantee the overall size of the big arch, and a large amount of refractory ramming material needs to be used to fill and repair the brick joints. However, the large amount of use of the refractory ramming material will cause fast erosion, shorten the service life of the furnace, and in severe cases, the big arch may collapse. In addition, during the erosion process of the big arch, the falling materials will fall into the glass liquid, affecting the quality of the glass.

[0004] Currently, there are mainly two types of arch forms: wooden arch form and iron arch form.

[0005] The wooden arch form is made of wood to form an arch membrane that meets the design arc of the glass. It is usually made in place within the coverage range of the big arch. The disadvantages of the wooden arch form are: ① low precision of the arch form; ② cannot be reused; ③ long production cycle; ④ after the completion of the masonry of the big arch, the arch form is difficult to remove; ⑤ serious waste of wood.

[0006] The iron arch form is a pre-made iron arch membrane that meets the design arc of the glass. During the construction process, the iron arch form is moved to the next section after the completion of the masonry of the section. The advantages of the iron arch form are high precision of the arch form, short production cycle, and easy to remove. However, the disadvantages are: ① during the construction process, the precision of the arch form deviates and is not easy to adjust; ② cannot be used in the masonry of different specifications of furnaces; ③ the narrow use range of the prepared arch form leads to idle and waste of iron resources. Therefore, it is particularly important to solve this problem. SUMMARY

[0007] In view of the above problems, the present application provides a modular arch form for glass furnace masonry, which is easy to assemble and disassemble, convenient to obtain materials, and has high resource utilization rate.

[0008] In order to realize the above technical scheme, the application provides a module type arch block for glass kiln masonry, which comprises a plurality of arch block modules, the arch block module comprises a supporting base and a moving base, a scaffold is arranged between the supporting base and the moving base, a lifting top plate which is in contact with the arch bricks is arranged on the supporting base, the lower surface of the arch brick is in close contact with the upper surface of the lifting top plate, a roller is arranged under the moving base, and the scaffold is composed of steel pipes.

[0009] Further improvement lies in that horizontal connecting plates are connected between the lifting top plates on the supporting bases of adjacent arch block modules.

[0010] Further improvement lies in that the main body of the supporting base is a U-shaped channel steel plate, a plurality of bolt holes are uniformly arranged in the middle of the bottom of the U-shaped channel steel plate, steel plates are welded at both ends of the U-shaped channel steel plate, and reinforcing ribs for fixing the steel pipes are arranged on the surface of the steel plates.

[0011] Further improvement lies in that the lower surface of the lifting top plate is provided with supporting pads, the height and number of the supporting pads are arranged according to the installation requirements of the arch bricks, and the supporting pads are made of channel steel.

[0012] Further improvement lies in that bolt holes are arranged on the supporting pads so as to be fixed on the supporting bases and the connecting plates.
