Description
Technical field
It is particularly a kind of for improving the choke block of flue gas in roller kilns the invention mainly relates to roller kilns choke block, it is main
It is used for the fields such as the roller kilns kiln thermal energy throttling of architectural pottery domestic ceramics.
Background technology
Architectural pottery and domestic ceramics are fired mainly by roller kilns, and roller way kiln is long, generally at 135 meters extremely
325 meters are differed, and sintering procedure is since first stage cold stage, this when, 300 degree of kiln temperature, mainly discharged green body
Absorption water, allow green body volume contraction, green body made to enter the reduction of kiln moisture, improves kiln production efficiency, second stage oxygenolysis
Stage, the temperature in this stage are between 300 degree of -950 degree, and clay and its other enhydrites is mainly allowed to exclude constitution water,
Carbonate decomposition, carbon and oxidation operation, into the porcelain stage, the temperature in this stage is 950 degree, main for phase III high temperature vitreous
If glaze is melt into vitreum, product strength increases, the porosity is allowed to reduce, green body is made drastically to shrink, fourth stage cooling rank
Section, mainly liquid phase crystallization, glass phase mass sets, because its kiln space is Horizontal type, heat smoke leads in long kiln
Discharged fume toward kiln hood in road from burning till high-temperature area, temperature curve progressively heats up from kiln hood to high temperature section, and product 950 degree when
Time is a heat absorption peak area, and product needs the process of oxidation exhaust slowly, and speed is too fast then to aoxidize that exhaust is bad, and speed is too
Slow kiln temperature can continue to raise, and when the temperature is excessively high, liquefaction can be then melted in the glaze of product surface too early, and confining surface is too early
Afterwards, gas can not discharge, and product is just present with the quality problems such as pastiness, pore, bubble, in sintering procedure particularly
When 600 degree ~ 950 degree, product needs substantial amounts of heat absorption, and during 950 degree of high temperature sections are exothermic, product needs again
More slowly it is better to reach effect, and this is a contradiction for flue gas Horizontal type, then aoxidizes insufficient, then kiln temperature slowly soon
It is too early to raise glaze face closure, gas row does not go out, in order to solve this problem current roller kilns are the vertical direction in kiln
Build firebreak and fireguard by laying bricks or stones, but cannot actually solve flue gas it is too high or too low and caused by product quality problem, for existing
Quality problems caused by the firebreak and fireguard of kiln can not change flue gas develop flue gas in a kind of New Roller Kiln and lead
Flowing plate.
The content of the invention
The defects of for above-mentioned traditional roller kilns fireguard and firebreak, this field work is engaged in present invention accumulation for many years
Experience by studying demonstration repeatedly, obtains smoke deflector in a kind of New Roller Kiln of the utility model and generates eventually.
For the above-mentioned prior art, the utility model technical problems to be solved are that this structure is totally different from current Vertical Square
To firebreak, fireguard, but by horizontal guiding flue gas, change flue gas and product exposure number, to provide production
The heat that product need before 950 degree, and delayed the melting temperature of product, it will not generate bubble and pin hole etc. beneficial to product exhaust
Feature.
In order to solve the above-mentioned technical problem, smoke deflector in a kind of New Roller Kiln mainly includes roller kilns entirety, institute
The whole front of roller kilns stated has into Zhuan Kou, and described to connect the easy fired stage into brick mouth, the easy fired stage connects
Connect heating and oxidation catabolic phase, the oxygenolysis stage connects high temperature vitreous into the porcelain stage, and the high temperature vitreous is into porcelain
Stage connects cooling down stage, main feature：Further include flue gas intercepter plate and flue gas collector plate, the flue gas intercepter plate
Clamping plate and smoke adjustable plate are installed with having in flue gas collector plate, the flue gas choke block and the flexible connection of flue gas collector plate, institute
It states installation clamping plate to be arranged on the both sides of the edge of flue gas intercepter plate, the installation clamping plate is used to fix flue gas intercepter plate and flue gas
Collector plate, the smoke adjustable plate are used to adjust the size of flue gas intercepter plate and flue gas collector plate thermal energy smoke, the cigarette
Gas intercepter plate is mounted in the region of heating and oxidation catabolic phase, and the flue gas collector plate is mounted in high temperature vitreous into the area in porcelain stage
Domain, the flue gas shut off plate shape for arc, and quantity is two pieces, and nock is towards the line of production, and each one piece up and down, roller kilns exist
300 degree ~ 950 degree scopes reach energy-saving effect, the flue gas afflux plate shape is using high-temperature flue gas is shunted by radian
Arc, quantity are two pieces, and each one piece up and down, with nock towards kiln body direction, arc facing away from product, and roller kilns are 950 degree ~ 1050
Degree scope makes to make fume centralized by the arc back of the body, i.e., along roller kilns horizontal direction, without being vertically oriented, controls flue gas flow,
Then high-temperature flue gas concentration is delivered heat into product, the easy fired phase temperature is 300 degree, and the heating and oxidation decomposes
Phase temperature be 300 degree ~ 950 degree, the high temperature vitreous into porcelain phase temperature be 950 degree ~ 1050 degree.
To solve the above-mentioned problems, operation principle is used by smoke deflector in a kind of New Roller Kiln of the utility model：
Deflector is recessed to flue gas intercepter plate and flue gas collector plate, one convex one using negative and positive two, and curved angle is root between 30 ° to 45 °
According to yield and kiln adjustable in length size, using 310 stainless steels, flue gas intercepter plate is installed in 300 degree -950 of kiln
Heating and oxidation catabolic phase, this stage are mainly used for discharging constitution water, carbonate decomposition, carbon and the organic matter oxygen of products material
Change, quartz crystal converts and, it is necessary to extend time oxygenolysis, this stage needs substantial amounts of thermal energy cigarette for liquid phase appearance on a small quantity
Gas, flue gas intercepter plate can shut off the required a large amount of thermal energy in one's respective area, while solve flue gas and need to extend before 950 degree
The problem of without being rapidly heated, flue gas collector plate, into position between the porcelain stage, are installed mounted in 950 degree of -1000 degree high temperature vitreous
After this deflector, being split 1000 degree of positions for flue gas make its subparticipation and product heat exchange, during to 850 degree, and quilt
Another group of collector plate is collected, and more thermal energy flue gases are provided for product, and prematurely melt surface liquefaction is closed.
The major advantage of smoke deflector in a kind of New Roller Kiln：
1st, solving flue gas needs to extend discharge gas before 950 degree.
2nd, solve product and be quickly raised to high temperature after 950 degree and reach and be rapidly heated, save thermal energy.
3rd, heating rate of the flue gas before 950 degree is adjusted, increases the utilization rate of kiln thermal energy, production capacity 10%, cigarette can be improved
The reasonable distribution of gas thermal energy, can save energy 10% or so.
