Description

A kind of glass industry pure oxygen burning rifle brick

Technical field

The utility model relates to a kind of glass industry pure oxygen burning rifle brick, belong to used a kind of equipment when making glass in the ceramic industry glass specialty, be specially adapted to the pure oxygen burning rifle of big flow, also be fit to the burning rifle of common air-breathing formula certainly.

Background technology

At present,, more and more attempt large tank furnace used advantage along with the development of cell furnace, relative productivity, investment will be saved, and operation is stable, and energy consumption is low; The large tank furnace used essential big burning rifle that is equipped with, big burning rifle also possesses heat utilization ratio height, low power consumption and other advantages simultaneously.Particularly the pure oxygen burning technology has reduced airborne 80%N ₂The heat of taking away, pure oxygen generate has only water vapour and CO2, has reduced exhausted air quantity greatly, has reduced the off gas treatment amount, so the economic benefit that pure oxygen burning brings is very large.Particularly for the founding of big tank furnace, long, the bright and temperature advantages of higher of pure oxygen burning flame, so the tank furnace pure oxygen burning will be the trend of Future Development, the rifle of big flow also must be used.

The burning rifle of big flow is also more and more higher to the requirement of rifle brick simultaneously, the rifle flame temperature height of big flow, gas velocity is big, flame is big, burn the spray gun brick so easily, the spray gun brick will be accelerated erosive velocity, particularly on the pure oxygen burning rifle, the pure oxygen burning flame temperature was very high, and outer scorching temperature is all more than 2000 degrees centigrade, and the rifle brick just burnt a big openning at 1-3 months, then burn the more refractory materials of deep layer, thereby reduced the life-span of space wall, the pure oxygen burning rifle brick of general big flow has only 2-3 month life-span, and the refractory materials of rifle brick periphery is emptied and continued to corrode to the brick of rifle periphery substantially after 3 months.

In order to improve the life-span of rifle brick, become the problem of some rifle manufacturers and refractory materials manufacturer research, they solve whole problem from the erosion resistant aspect that improves refractory materials, but because pure oxygen burning rifle flame temperature is too high, thereby cause rifle brick temperature too high, add the erosion of overdraught, the rifle brick life-span still can not get very long raising, the general life-span that just doubles, but the rifle brick price after the improvement material but is several times of original rifle brick, and the rifle brick compactness after improving is higher, adds that rifle brick volume is bigger, bring very big difficulty to hot swap, the success ratio of this brick hot swap also has only 70%.

The utility model content

The purpose of this utility model is to overcome above shortcomings in the prior art, and a kind of reasonable in design is provided, and production cost is low, long service life, and hot swap is easy to glass industry pure oxygen burning rifle brick.

The technical scheme in the invention for solving the above technical problem is: a kind of glass industry pure oxygen burning rifle brick, comprise refractory brick, have through hole on this refractory brick, it is characterized in that: also comprise support body, thermofin and rifle installation suspension hook, described support body is that hollow and bottom have groove, this support body is fixed on the refractory brick, and described rifle is installed suspension hook and is connected on the support body, and described thermofin wraps in around refractory brick and the support body.

The bottom of support body described in the utility model is out slotted flat board.

Support body bottom periphery described in the utility model is provided with the fluid channel, is provided with import and outlet in this fluid channel.

Support body described in the utility model is that stainless steel is made.

Support body described in the utility model is fixed on the refractory brick by screw.

The material of thermofin described in the utility model is the soak cotton.

The utility model compared with prior art, have the following advantages and effect: the utility model in use, refractory brick is positioned at the inboard of cell furnace, directly contact with melting furnaces the inside high-temp waste gas, the support body that stainless steel is made is positioned at the cell furnace outside, and this support body hollow can reduce the temperature of monoblock rifle brick by adding the refrigerative mode, so just effectively reduce the rifle brick temperature that contacts with melting furnaces high temperature, improved the anti-erosional competency of rifle brick.

Because the utility model comprises refractory brick and the outer side frame body that directly contacts with melting furnaces the inside high-temp waste gas, when refractory brick of the present utility model is needed to change the rifle brick by high temperature erosion, it is just passable only to need to change refractory brick, because little before the inboard refractory brick volume ratio, being easy to operation during hot swap changes, the temperature difference is also more much smaller than in the past, and being replaced with power almost is 100%.It is convenient not only to change, and has saved the cost of changing.

The utility model is installed in the cell furnace, is cotton and contacted with the high temperature pool wall of periphery by outer field soak, so just can reduce the temperature of rifle brick.
