Abstract
The invention relates to a high temperature carbonization furnace hearth, which is composed of an upper hearth plate and a lower hearth plate and side plates disposed at both sides of the upper hearth plate and the lower hearth plate. Each hearth plate is formed by splicing of several silicon carbide pressed panels, and each side plate is formed by splicing of several silicon carbide pressed vertical plates. Interconnected L-shaped edge ports are disposed around the panels, interconnected L-shaped edge ports are disposed on left and rights sides of the vertical plates, and arc flanges are arranged on upper and lower side edges of the vertical plates. The panels connecting the upper hearth plate and the lower hearth plate and the side plates are provided with grooves fitting the vertical plate flanges. A high temperature adhesive is arranged at the joints of panels and panels, side plates and side plates, as well as panels and the side plates. According to the invention, super-wide and super-long large size high temperature carbonization furnace hearth in line with sealing requirements can be spliced conveniently, thus laying a good foundation for manufacturing large size high temperature carbonization furnaces or large size carbon fiber carbonization production lines. The joints of the hearth plates and the side plates are bonded together through the high temperature adhesive, thus having sealing performance and also being in favor of the sealing performance of the hearth.
Description
Technical field
The present invention relates to a kind of high temperature carbonization furnace, particularly a kind of carbon fiber production wide cut carborundum sealing burner hearth.
Background technology
High temperature carbonization furnace is one of the key equipment during carbon fiber is produced, and burner hearth is the critical component of high temperature carbonization furnace, and burner hearth requires to bear long-term 1400 ° of C high temperature, and has air-tightness, and oxygen must not be had under minute-pressure to enter in burner hearth.What small size high temperature carbonization furnace hearth adopted is overall silicon carbide hearth.When needs large scale wide cut high temperature carbonization furnace, overall silicon carbide hearth manufacture can not realize too greatly due to size, needs the measure taking other.
Summary of the invention
Technical problem to be solved by this invention is for the deficiencies in the prior art, provides a kind of reasonable in design, can make large-sized high temperature carbonization furnace hearth of super-long and super-wide.
Technical problem to be solved by this invention is realized by following technical scheme, the present invention is a kind of high temperature carbonization furnace hearth, be made up of upper and lower two-layer furnace plate and the side plate being located at upper and lower two-layer furnace plate both sides, its characteristic point is: the flat plate splicing that described furnace plate is suppressed by some blocks of carborundum forms, the riser that described side plate is suppressed by some blocks of carborundum is spliced, dull and stereotyped surrounding is provided with the L shape bead of docking mutually, the left and right sides of described riser is provided with the L shape bead of docking mutually, the dual-side up and down of riser is provided with circular arc flange, the flat board that upper and lower furnace plate connects with side plate is provided with the groove coordinated with riser flange,
High temperature adhesive is provided with flat board, side plate and side plate, flat board and side plate joint dull and stereotyped, high temperature adhesive is made up of the raw material of following weight proportion, sodium metasilicate: silica: alumina silicate: carborundum: zirconia=100-400:50-100:2-20:20-40:20-40; Sodium metasilicate is the aqueous solution of sodium metasilicate, and mass concentration is 30%; Silica, alumina silicate, carborundum, zirconia are that granularity is greater than 300 object solid particles; Add water after fully being mixed by above-mentioned raw materials during construction furnishing pasty state, and each block of flat board, side plate are bonded together securely.
Pasty state high temperature adhesive is filled at dull and stereotyped and flat board, side plate and side plate, dull and stereotyped and side plate joint, makes easy construction.By the ratio of each raw material of adjustment high temperature adhesive, high temperature adhesive can be made not only each piece of carborundum plate of burner hearth to be bonded together securely under high temperature furnace operating temperature, but also there is certain plasticity, the gap of expanding with heat and contract with cold and likely producing because of burner hearth expanded by heating and distortion and blowing out blow-on can be made up at any time.So just can ensure the sealing of high temperature carbonization furnace silicon carbide hearth, and make it have quite long service life.
Compared with prior art, the present invention can be spliced into the satisfactory large scale high temperature carbonization furnace hearth of sealing of ultra-wide, overlength easily, thus is that making large high-temperature retort or large-scale carbon fibre carbonizing production line lay the foundation; The joint of furnace plate and side plate is bonded together by high temperature adhesive, and it both had sealing, is beneficial to again the air-tightness of burner hearth.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Fig. 2 is dull and stereotyped and the structural representation of riser splicing.
Fig. 3 is structural representation that is dull and stereotyped and flat plate splicing.
Detailed description of the invention
Referring to accompanying drawing, further describe concrete technical scheme of the present invention, so that those skilled in the art understands the present invention further, and do not form the restriction to its right.
With reference to accompanying drawing 1, Fig. 2 and Fig. 3, a kind of high temperature carbonization furnace hearth, be made up of with the side plate 1 being located at upper and lower two-layer furnace plate 2 both sides upper and lower two-layer furnace plate 2, the flat board 4 that described furnace plate 2 is suppressed by some blocks of carborundum is spliced, the riser 5 that described side plate 1 is suppressed by some blocks of carborundum is spliced, the surrounding of dull and stereotyped 4 is provided with the L shape bead 3 of docking mutually, the left and right sides of described riser 5 is provided with the L shape bead 3 of docking mutually, the dual-side up and down of riser 5 is provided with circular arc flange 7, the flat board 4 that upper and lower furnace plate 2 connects with side plate 1 is provided with the groove 6 coordinated with the flange 7 on riser 5.L shape bead 3 longer dimension, is conducive to sealing, and the docking mode of circular arc flange 7 and groove 6, stress can be reduced while guarantee sealing and concentrate.
Be provided with high temperature adhesive with side plate 1, dull and stereotyped 4 with side plate 1 joint in dull and stereotyped 4 and flat board 4, side plate 1, carry out encapsulation process by high temperature adhesive.High temperature adhesive is by the raw material of following weight proportion
Form, sodium metasilicate: silica: alumina silicate: carborundum: zirconia=100-400:50-100:2-20:20-40:20-40; Sodium metasilicate is the aqueous solution of sodium metasilicate, and mass concentration is 30%; Silica, alumina silicate, carborundum, zirconia are that granularity is greater than 300 object solid particles; Add water after fully being mixed by above-mentioned raw materials during construction furnishing pasty state, makes each piece of flat board 4, side plate 1 bonds together securely.
