Description

Pottery kiln-changing controllable kiln

Technical Field

The utility model belongs to a pottery firing equipment specifically is a pottery kiln becomes controllable kiln.

Background

The faming is the change of the difference of the colors of the surfaces of the same pottery or the same pottery due to different factors such as oxidation-reduction atmosphere and the like in the process of firing the pottery blanks. This phenomenon is naturally occurring at present and cannot be artificially controlled. For example, the surface of the pottery is changed into different colors due to the non-uniformity of the reduction strength in the same batch of the pottery blanks in the gas kiln, and for the result, what color and brightness appear at which part of a certain pottery can not be predicted in advance, and what is obtained by firing the pottery blanks along with the edge. Except that red purple pottery is fired, certain reducing materials, such as coal, coke, wood slag, sawdust and other carbon-containing fuels are added into a furnace chamber to artificially control the firing of the red purple pottery into black, but other colors are often mixed in red. Even with such black results, it is difficult to control, and only marginally, and naturally, the same transmutation effect cannot be reproduced artificially.

Detailed Description

The invention is further described below with reference to the accompanying drawings and examples.

As shown in fig. 1-3. The furnace body 2 and the furnace top 5 are welded into a square box structure by steel plates with the thickness of 3-5mm, and the lining layer 22 is made of refractory and heat-insulating materials such as heat-insulating cotton. The material and structure of the lining layer, the support piers 21, the bottom plate bricks 20, and the electric heating strips 19 are substantially identical to those of the existing electric kiln, and are not described in detail herein.

The through hole 3 and the hole plug 14 are generally made by firing raw materials such as purple pottery clay, refractory clay and the like. As mentioned above, the through hole has a certain taper, the inside is small and the outside is large, so that the through hole can be matched with the hole plug for plugging. And a circle of flange is arranged at the outer opening of the through hole so as to be convenient for embedding and mounting. The top ribs 11 are two angle steels welded on the furnace top to increase the strength and prevent the furnace top from deforming, and are also used for being connected with the diagonal brace 10 to install the whole furnace top. Two pulleys 7 are arranged on a pulley shaft 13 to rotate, and two ends of the pulley shaft are welded between two inclined support rods. In order to increase the strength of the pulley shaft, an angle steel is additionally welded below the pulley shaft to be used as a reinforcing rod 9. The diagonal brace and the top rib are connected by a pin shaft 17, so that the furnace top can turn over around the pin shaft.

The hardness of the two springs 15 is determined according to the size of the furnace top and the principle of being convenient to open the furnace top. The lower end of the spring is fixed on the lower frame edge of the frame rib 16 or the furnace wall, the upper end is connected with a steel rope 23, the steel rope is tightly tied on a cross pull rod 25 by winding a pulley, thus a pretension force is formed between the furnace top and the furnace body, the furnace top is convenient and labor-saving to open, and the furnace top can be kept tight when being covered by the furnace buckle 4.

The frame ribs 16 are also welded on the back of the furnace body by angle steel, thereby not only increasing the strength of the furnace wall, but also playing the role of connecting with the inclined stay bars and installing springs. The upper and lower rims of the frame rib may be omitted or partially omitted.

The support legs 1 of the furnace body are welded with the furnace body into a whole.

The hand grip 13 is welded to the top bar by a reinforcing bar.

The parts and reference numerals not mentioned are as described above.

The utility model discloses this kind of pottery transmutation controllable kiln mainly controls to the purple pottery transmutation of building water that the applicant is located, nevertheless does not get rid of and is used for the pottery transmutation control of other types.

The following are some examples of purple pottery transmutation control:

example 1 purple ceramic teapot to be fired, red on one side and black on the other side, the dried greenware was placed on the hearth plate brick so that it was close to the through hole of the furnace wall, and if there were a plurality of greenware, they were arranged closely but not in contact, with a certain gap kept so as not to stick, and leaving the portion facing the through hole of the furnace top free. After the blank is placed, the top of the furnace is covered, all the through holes are plugged, the furnace is electrified to be heated, and the heating speed is set according to a common heating curve. The temperature rise curve can be adjusted according to the instruction of the electric kiln.

When the temperature rises to about 1100-1180 ℃, the temperature begins to be reduced, all through chamber holes are opened when the temperature is reduced to 1170 ℃, coal powder or mings (pine wood with resin) are put into the through chamber holes at the top of the furnace, and at the moment, black smoke is sprayed out of the through chamber of the furnace wall. After the input coal powder or the added semen is burnt out, the power supply is turned off, and the purple pottery transmutation product with black one surface and red other surface close to the furnace chamber through chamber hole can be obtained after the natural cooling and the drawing out of the kiln.

Example 2, to fire pure red purple pottery, the purple pottery blank is placed in the furnace chamber without contact, the furnace top is covered, all through chamber holes are plugged, the temperature is raised to 1100-1180 ℃, and the temperature is kept for 5 hours, thus obtaining pure red product.

Example 3 to fire a muddy white purple pottery ware, the purple pottery blanks were placed in the furnace hearth without contact, the furnace top was covered, all through hearth holes were plugged, the temperature was raised to 1200 and 1230 deg.C, and the muddy white purple pottery product was obtained after 5 hours.

In the above examples 2 and 3, if the through hole is opened halfway, a variegated furnace-transmural product is obtained. The part of the furnace transmutation is still close to the through hole, and the depth of the color is determined by the time of opening the hole. Unexpected transmutation products can be obtained by different combinations of openings and other elements, and fixed and reproducible transmutation results can be obtained by determining protocol records corresponding to such effects and then performing the protocol records as usual.
