Embodiment 1

[0022] The method proposed by the present invention is to use shale as a raw material vacuum internal combustion type to burn green bricks and tiles, and it is carried out by the following steps successively:

[0023] (1) Measuring and preparing materials: The shale is blasted by blasting in the mountains, and the materials are manually selected and transported back to the workshop for standby, and the commercially purchased coal materials are used, and the raw materials are weighed according to the following weight:

[0024] 1 part shale,

[0025] Coal 0.25 parts,

[0026] Send the weighed raw materials into a pulverizer to pulverize to form a mixed material with a block size of 6mm, and then send the mixed material to a ray mill for ball milling to form a mixed powder with a particle size of 260 mesh.

[0027] (2) Stacking and aging: the prepared mixed powder is stacked indoors for natural aging treatment for 3 days, and the moisture inside the mixed powder can be completel...

Embodiment 2

[0035] The method proposed by the present invention is to use shale as the raw material vacuum internal combustion type to burn the green brick and tile method, is to carry out by following steps successively:

[0036] (1) Measuring and preparing materials: The shale is blasted by blasting in the mountains, and the materials are manually selected and transported back to the workshop for standby, and the raw materials are weighed according to the weight ratio as follows:

[0037] 1 part shale,

[0038] Coal 0.35 parts,

[0039] Send the weighed raw materials into a pulverizer to pulverize to form a mixed material with a block size of 10 mm, and then send the mixed material to a ray mill for ball milling to form a mixed powder with a particle size of 320 mesh.

[0040] (2) Stacking and aging: the mixed powder was stacked and aged indoors for 2 days.

[0041] (3) Vacuum billet making: Weigh the mixed powder that has been stacked and aged and put it into the mixer, and add 5% sa...

Embodiment 3

[0048] The method proposed by the present invention is to use shale as the raw material vacuum internal combustion type to burn the green brick and tile method, is to carry out by following steps successively:

[0049] (1) Measuring and preparing materials: Weigh raw materials according to the following weight:

[0050] 1 part shale,

[0051] Coal 0.1 part,

[0052] Send the raw materials into a pulverizer to pulverize to form a mixed material with a block size of 4 mm, and then send the mixed material to a ray mill for ball milling to form a mixed powder with a particle size of 220 mesh.

[0053] (2) Stack aging: stack the mixed powder indoors for natural aging for 1 day.

[0054] (3) Vacuum billet making: Put the mixed powder that has been stacked and aged into a mixer, add water according to 12% of the weight of the mixed powder, and then fully stir to make a uniformly stirred billet mud, and send it into the vacuum The blank can be made by extruding in the extrusion mol...

Abstract

The invention discloses a method for firing black tiles in vacuum internal combustion mode with shale as raw material, comprising the steps of batching, piling up and ageing, vacuum making blanks, airing and dehydrating, placing in kiln and firing, sealing kiln and smoldering, absorbing water smoke and delivering finished products, and its outstanding substantial character and remarkable advancement lie in that it uses the shale obtained by blasting for cutting a mountain to replace clay, and the black tile products have high intensity, good cold tolerance and frost resistnace, weather proofing, and osmosis proofing, and extremely large added value, and have completely remarkable economic and social benefits.

Description

Technical field: [0001] The invention relates to the production technology of green bricks and tiles, which belongs to the technical field of building ceramic bricks and tiles, and specifically relates to a method for firing green bricks and tiles using shale as a raw material in vacuum internal combustion, which is especially suitable for the production and manufacture of antique bricks and tiles. Celadon series products such as blue tube tiles, green roof tiles and blue wall and floor tiles. Background technique: [0002] With the rapid development of my country's national economy and the continuous improvement of the living standards of the broad masses of the people, the progress of my country's urbanization has been greatly promoted. The huge demand has objectively and effectively promoted the rapid development of my country's building materials market. At present, most of the brick and tile manufacturers in my country's building materials system use the traditional met...
