Description

Technical Field

[0001] The invention relates to the technical field of glass melting furnaces, and in particular to a checker brick masonry structure of a heat storage chamber of a glass melting furnace. Background Art

[0002] Glass melting furnaces are mostly equipped with regenerators when using gas fuel or liquid fuel for combustion. In the regenerator, multiple checkerboard bricks are stacked in order to form a checkerboard body. The checkerboard body is then used as a heat transfer medium to recover the waste heat of high-temperature flue gas by alternately storing and releasing heat. Specifically, the hot gas or smoke in the glass melting furnace first enters the regenerator through the top of the checkerboard body and releases heat energy to the checkerboard body; then, cold air is provided to the bottom of the heated checkerboard body to recover heat energy to form hot air. After leaving the top of the checkerboard body, the hot air is fed into the furnace burner to burn the fuel under optimal conditions. Since the checkerboard body needs to perform the above process alternately, it must have excellent thermal shock resistance.

[0003] When the temperature at the bottom of the regenerator of the glass melting furnace is lower than 800℃, sodium sulfate begins to condense on the brick surface and forms a layer of condensate. As time goes by, the thickness of the condensate layer will become larger and larger, causing the cross section of the flue opening to gradually become smaller, greatly reducing the heat storage capacity of the checker bricks. If the furnace is filled with more flying materials due to the use of broken glass or batch preheating, the condensate condensation phenomenon will be more serious. After the flue is blocked, mechanical or thermal cleaning is required, affecting production efficiency.

[0004] The channel aperture of the lattice body composed of conventional checker brick arrangements such as Siemens, basket weave, barrel brick and cross brick is between 140mm×140mm and 140mm×310mm. Due to the narrow channel aperture, it is easy to get clogged and difficult to clean. If the grid holes are enlarged in the traditional checker brick arrangement, the following problems will arise: there is no interlocking structure between the Siemens and basket weave checker bricks, which will be washed by air flow during use, and there is a risk of tilting or even collapse; barrel brick and cross brick are difficult to make due to the large volume of a single brick, and the quality cannot be guaranteed. Summary of the invention

[0005] In order to solve the above technical problems, the present invention provides a checker brick masonry structure of a glass melting furnace heat storage chamber with strong heat storage capacity.

[0006] The present invention adopts the following technical solution:

[0007] The present invention provides a checker brick masonry structure for a heat storage chamber of a glass melting furnace, comprising a plurality of checker body layers stacked and bonded in sequence from top to bottom, the checker holes on adjacent checker body layers are mutually connected in a one-to-one correspondence, each checker body layer is formed by bonding a plurality of rectangular checker bricks to each other, and the checker holes on the checker body layers are rectangular checker holes of 290 mm×290 mm to 370 mm×370 mm.

[0008] Preferably, a front tenon extends outward from the front side of the rectangular lattice brick, and a rear tenon extends outward from the rear side. Four rectangular lattice bricks are clamped and bonded into a cross-shaped assembly through two front tenons and two rear tenons. Multiple cross-shaped assemblies are clamped and bonded to each other to form a lattice body layer.

[0009] Preferably, the front and rear side surfaces of the rectangular lattice brick, the connection between the front tenon and the front side surface of the rectangular lattice brick, and the connection between the rear tenon and the rear side surface of the rectangular lattice brick are all processed with rounded corners.

[0010] Preferably, the upper top surface of the rectangular lattice brick extends outwardly with an upper tenon, and the lower bottom surface is concave inward to form a lower groove. In two adjacent lattice body layers, the lower rectangular lattice brick is engaged with the lower groove of the upper rectangular lattice brick through the upper tenon.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

Compared with the existing structure, the lattice holes are made larger and are particularly suitable for the bottom of the heat storage chamber.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0032] Furthermore, in the description of the present invention, unless otherwise specified, “plurality” means two or more.

[0033] See also Figures 1 to 3 The present embodiment provides a checker brick masonry structure for a glass melting furnace regenerator, comprising a plurality of checker body layers 1 stacked and bonded in sequence from top to bottom, the checker holes 2 on adjacent checker body layers 1 are mutually connected one by one, each checker body layer 1 is formed by a plurality of rectangular checker bricks 3 bonded together, and the checker holes 2 on the checker body layer 1 are rectangular checker holes of 290 mm×290 mm to 370 mm×370 mm.

[0034] The checkered brick masonry structure of the glass melting furnace regenerator of the present embodiment adopts rectangular grid holes of 290mm×290mm~370mm×370mm. Compared with the existing structure, the grid holes 2 are made larger, which is particularly suitable for the bottom of the regenerator, and solves the problem of easy blockage due to narrow grid holes, and has a strong heat storage capacity. The volume of the rectangular checkered brick 3 meets the current material production process, and the production is simple, and it is easier to control the processing quality of the checkered brick.

[0035] It should be noted that, since the rectangular checker brick 3 has a simple structure and the processing quality is easy to control, in actual use, in order to minimize the risk of clogging, the longitudinal length of the processed rectangular checker brick 3 can be flexibly selected.

[0036] Preferably, see Figures 4 to 6 The front side of the rectangular lattice brick 3 extends outward with a front tenon 31, and the rear side extends outward with a rear tenon 32. Four rectangular lattice bricks 3 are clamped and bonded into a cross-shaped assembly 4 through two front tenons 31 and two rear tenons 32. Multiple cross-shaped assemblies 4 are clamped and bonded to each other to form a lattice body layer 1.

[0037] The rectangular lattice bricks 3 can be connected to form a stable cross-shaped assembly 4 before bonding through the arrangement of the front tenon 31 and the rear tenon 32, thereby ensuring that the lattice brick masonry structure of the glass melting furnace heat storage chamber of this embodiment has better stability while making the lattice holes larger.

[0038] Preferably, see Figure 5 The front and rear sides of the rectangular checker brick 3, the connection between the front tenon 31 and the front side of the rectangular checker brick 3, and the connection between the rear tenon 32 and the rear side of the rectangular checker brick 3 are all processed with rounded corners 33. The setting of the rounded corners 33 can provide guidance when the rectangular checker brick 3 is clamped and spliced ​​through the front tenon 31 and the rear tenon 32, further improving the stability of the single checker body layer 1.

In two adjacent lattice body layers 1, the lower rectangular lattice brick 3 is engaged with the lower groove 35 of the upper rectangular lattice brick 3 through the upper tenon 34.

[0040] The rectangular lattice bricks 3 can be connected to form a stable lattice layer stacking structure before bonding through the arrangement of the upper tenons 34 and the lower grooves 35, thereby ensuring that the lattice brick masonry structure of the glass melting furnace heat storage chamber of this embodiment has larger lattice holes while making the stability and corrosion resistance of the entire masonry structure better.

[0041] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principles of the present invention. These improvements and substitutions should also be regarded as the scope of protection of the present invention.
