Abstract
The utility model relates to an improved sintering kiln, which is suitable for sintered magnetic material, electrotechnical porcelain, ceramics, etc. Measures of high-temperature heat-insulating material outer wrapping, kiln car brick hollow ware, leading shaped box body, etc. are taken to overcome the deficiency of big energy consumption, and low production and yield in a kiln-vehicle type tunnel kiln. The productive potential of an original kiln is digged thoroughly.
Description
The present invention is a kind of improved sintering oven.Be applicable to the invention of sintered magnetic material, electroceramics and pottery.
Present widely used car tunnel kiln is compared with previously used clearance-type kiln, has the output height, and it is low to consume energy, and work continuously.But compare with roller-bottom type, push-plate type or air-cushion type tunnel cave that newly-developed gets up, it is big to exist tangible power consumption, and the sealing heat-insulating property is poor, and upper and lower temperature difference is big in the kiln road, and yield rate is low, defective such as yield poorly, so its development is greatly limited.Roller-bottom type, push-plate type or air-cushion type tunnel cave are bigger owing to investing again, complex structure, and operation requires high, maintenance difficult etc., thereby be difficult to be extensive use of, especially rarely found in township industry.
At the problem of above-mentioned existence, task of the present invention is that car tunnel kiln is comprehensively improved, and reaches the saving energy, improves output, reduces the temperature difference in the kiln, improves yield rate, fully excavates the productive potentialities of former kiln.
The present invention is the high insulation material of refractory brick liner (4) outer wrapping (6) at high temperature section kiln body, protects at high insulation material external application iron sheet (8) outer cover again.Place the combining form of kiln car brick (3) employing more than 2 on the kiln car (2), middle formation is hollow, and there is raised line the side of brick, and once sintered shaping is then at the high insulation material of hollow parts filling (14).Place saggar on the kiln car brick by parallel, or intersect or stamp circular hole with the rule that sinter shape, size adapt.The method of manipulating after the improvement is identical with former kiln.
The present invention with binding agent the method that insulation material is bonded to refractory brick liner the inside is compared, can avoid because ageing of binders lost efficacy, insulation material directly contacts and powder of detached with high temperature, causes stopping defectives such as kiln repairing.The present invention is clipped in high insulation material between refractory brick liner and the iron sheet outer cover, thus can increase thickness, to improve heat insulating ability.The high insulation material of kiln car brick (3) hollow filling reduces energy consumption.Saggar is to place sinter, punches on saggar, and the interior hot gas of kiln is circulated up and down, has reduced upper and lower temperature difference, thereby has improved the yield rate of product, and can tie accurate electroceramics, pottery and the electronics magnetic material of having relatively high expectations with the klining after this improvement.
The kiln car formula tunnel electrical kiln that is sintering electronics magnetic material below improves technology, the economic indicator contrast table of front and back:
Former kiln improves kiln
Power consumption 142KWH 110KWH
700 2088 of output
Yield rate 80～85%＞90%
The high gear product can not sintering energy sintering
Below in conjunction with accompanying drawing invention is further described:
Fig. 1: the cutaway view of comprehensive improved kiln car formula high temperature section tunnel cave.
Fig. 2: the A-A cutaway view of kiln car brick (3).
Fig. 3: the B-B cutaway view of kiln car brick (3).
Fig. 4: the hole becomes the saggar of cross arrangement.
Fig. 5: the saggar that the hole becomes to be arranged in parallel.
When this invention is used for the kiln car formula high temperature section tunnel electrical kiln of sintered magnetic material, as shown in Figure 1, at refractory brick liner (4) coated outside soak material (6), the most handy alumina silicate fiber felt, its thickness with 120～180mm for well.The insulation material outside is protected with iron sheet outer cover (8).Be bearing on the kiln car brick (3) after saggar (5) multilayer of dress workpiece is stacked, the kiln car brick is held on again on the kiln car (2), and kiln car advances on track (1) gradually.Whole high temperature section heats with Elema (7) energising.Kiln car brick hollow filling soak material (14) shown in Figure 2, the most handy alumina silicate fiber felt, its gross thickness is good with 140～220mm, kiln car brick (3) divides three combinations, so that make.There is raised line (10) brick (11) side, matches with sealing strip (9) on the kiln body, and to reduce gas leakage and thermal radiation loss, brick (12) is gone up and deployed a lid (13), in order to take up the saggar (5) of workpiece.Fig. 4 and saggar (5) shown in Figure 5, its bottom be by intersecting or parallel, or beat circular hole with the rule that sinter shape, size adapt, and makes that thermal current can be by circular hole on the several layers of saggar and circulation up and down, temperature difference about reducing in kiln the road in.
Adopt technology of the present invention,, improve a kind of work of kiln car brick (3) and saggar (5) is corresponding to high temperature section kiln body cladding insulation material (6), just can receive certain economic benefits, if do comprehensive the improvement, effect is better, can accomplish more than 10,000 yuan of moon initial cost, all regain the end of month.The present invention can promote the large scale sintering kiln of the noncontinuity production that is used for other non-car tunnel kiln.
