Embodiment 1

[0036] A preparation process of an ecological brick using domestic waste incineration slag as a raw material, specifically comprising the following steps:

[0037] Step 1. Put 40 parts by weight of slag into a drying oven to dry first, then put it into a ball mill after drying, pass through a 100-mesh sieve after ball milling, take the slag from the bottom of the sieve for later use, and return the slag on the sieve to the ball mill for ball milling again;

[0038] Step 2. Dissolve 0.1 parts by weight of water strength agent in water and prepare a 0.5% aqueous solution of water strength agent for future use. Mix 3 parts by weight of cement, 4 parts by weight of gypsum powder, 10 parts by weight of lime powder and 2 parts by weight of silicon Sodium bicarbonate is mixed and passed through a 200-mesh sieve to obtain a mixed powder. The slag sieved in step 1 is added to the mixed powder, and then an aqueous solution of a water strength agent is added for stirring and mixing. After...

Embodiment 2

[0045] A preparation process of an ecological brick using domestic waste incineration slag as a raw material, specifically comprising the following steps:

[0046] Step 1. Put 50 parts by weight of slag into a drying oven to dry first, and then put it into a ball mill after drying, pass through a 200-mesh sieve after ball milling, take the slag at the bottom of the sieve for later use, and return the slag on the sieve to the ball mill for ball milling again;

[0047] Step 2. Dissolve 0.15 parts by weight of water strength agent in water, and prepare an aqueous solution of water strength agent with a mass fraction of 0.8% for later use. Mix 4 parts by weight of cement, 5 parts by weight of gypsum powder, 11 parts by weight of lime powder and 2 parts by weight of silicon Sodium bicarbonate is mixed and passed through a 200-mesh sieve to obtain a mixed powder. The slag sieved in step 1 is added to the mixed powder, and then an aqueous solution of a water strength agent is added fo...

Embodiment 3

[0054] A preparation process of an ecological brick using domestic waste incineration slag as a raw material, specifically comprising the following steps:

[0055] Step 1. Put 60 parts by weight of slag into a drying oven for drying first. After drying, add it to a ball mill. After ball milling, pass through a 300-mesh sieve. Take the slag at the bottom of the sieve for later use. The slag on the sieve is returned to the ball mill for ball milling again;

[0056] Step 2: Dissolve 0.2 parts by weight of water strength agent in water, and prepare a 1% aqueous solution of water strength agent by weight for future use. Mix 5 parts by weight of cement, 6 parts by weight of gypsum powder, 12 parts by weight of lime powder and 3 parts by weight of silicon Sodium bicarbonate is mixed and passed through a 200-mesh sieve to obtain a mixed powder. The slag sieved in step 1 is added to the mixed powder, and then an aqueous solution of a water strength agent is added for stirring and mixing...

Abstract

The invention discloses a preparation process of an ecological brick taking household garbage incineration slag as a raw material. The preparation process comprises the following steps of 1, drying, ball-milling and sieving the slag; 2, preparing an aqueous solution of a water strength agent, uniformly stirring the raw materials, and passing through an edge runner mill to prepare a brick raw material; 3, pressing and molding the brick raw material into green bricks by using a green brick molding machine; and 4, moving the green bricks into a steam curing chamber for curing, and then transferring the green bricks into a finished product warehouse for storage so as to obtain ecological brick finished products. The green brick molding machine comprises a feeding part, a pushing part, a molding part, a pressing part, a base and a rack assembly, the pushing part is located on one side of the rack assembly, the feeding part is located above the pushing part, the pressing part is located above the interior of the rack assembly, the molding part is located in the rack assembly, the molding part is located below the pressing part, and the base is located below the molding part. The preparation process solves the problems of low strength and poor durability of the ecological brick prepared from the household garbage incineration slag in the prior art.

Description

technical field [0001] The invention belongs to the technical field of ecological brick preparation, and in particular relates to a preparation process of an ecological brick using domestic garbage incineration slag as a raw material. Background technique [0002] Each ton of domestic waste can produce 0.2 tons of slag after incineration. The slag of domestic waste incineration is mainly composed of ceramics, glass, metal, incompletely burned organic matter and non-combustible inorganic matter. The density of domestic waste incineration slag is about 2.3g / cm 3 , pH 8-13, containing about 38% SiO 2 , 22% CaO, 10% Al 2 o 3 , 4.6% Fe 2 o 3 , 3% MgO, and a small amount of K 2 O, Na 2 O et al. In addition, the contents of Pd, Cu and Zn in MSW incineration slag were 26, 14 and 13 times the average contents of soil. Therefore, direct landfill or utilization of slag will pollute the environment. With the acceleration of the construction of domestic waste incineration power ...
