Embodiment 1

[0021] a. Raw material preparation: Naturally dry the sugar beet sugar filter sludge obtained by the carbonation method to make the relative moisture content ≤ 13%; crush the obtained sugar filter sludge and pass through a 100-mesh sieve; crush waste ceramics to a particle size of 0.85-2.00 mm; pulverize coal Ash and clay are passed through a 160-mesh sieve.

[0022] b. Blank making: according to the mass percentage of the permeable brick formula: 22% of pore-forming agent sugar filter mud, 25% of fly ash, 30% of clay, and 23% of waste ceramics. Weigh various prepared raw materials and mix them with water. The required water is 10% of the absolute dry mass of the batch; stir for 3 hours to make it evenly mixed; put the stale material into the brick press for 48 hours after granulation, and the pressure is 20MPa; put the shaped bricks into In a drying oven, the drying temperature is 105° C., and the drying time is 6 hours to obtain a green body.

[0023] c. Sintering: Put the ...

Embodiment 2

[0026] a. material preparation: same as embodiment 1.

[0027] b. Billet making: according to the mass percentage of raw materials: 24% of pore-forming agent sugar filter mud, 25% of fly ash, 29% of clay, and 22% of waste ceramics. It is 12% of the absolute dry mass of the batching material; stir for 3 hours to make it evenly mixed; put the aged material into a brick press for 48 hours after granulation, and put the molded brick into a drying box , a drying temperature of 108° C. and a drying time of 6 hours to obtain a green body.

[0028] c. Sintering: Put the dried bricks into a box-type electric furnace, sinter them at 1100°C, keep them warm for 1 hour, and then they will become permeable bricks after cooling with the furnace.

Embodiment 3

[0030] a. material preparation: same as embodiment 1.

[0031] b. Blank making: according to the mass percentage of the permeable brick formula: 25% of pore-forming agent sugar filter mud, 25% of fly ash, 30% of clay, and 20% of waste ceramics. Weigh various prepared raw materials and mix them with water. The required moisture is 13% of the absolute dry mass of the batch; stir for 3 hours to make it evenly mixed; put the stale material into the brick press for 48 hours after granulation, and the pressure is 20MPa; put the formed brick into In a drying oven, the drying temperature is 108° C., and the drying time is 6 hours to obtain a green body.

[0032] c. Sintering: put the dried bricks into a box-type electric furnace, sinter them at 1110°C, keep them warm for 0.5h, and cool them down with the furnace to become permeable bricks.

Abstract

A method for manufacturing a water permeable brick by using sugar filter mud uses industrial waste residue of the sugar filer mud as a pore-forming agent, uses thermal power plant fly ash as main raw materials, adopts clay as a binding agent, and adopts waste ceramic as aggregate. A finished product is obtained through dosing, stirring, staling, molding, drying and sintering of the raw materials and other steps. Forming of pores of the water permeable brick manufactured by the method is achieved by mainly using gas generated by high temperature decomposition of the sugar filter mud. The water permeable brick manufactured by the method is not only simple in process, low in production cost, but also good in water permeability, high in mechanical strength and suitable for paving sidewalks, courtyard alleys, park garden paths, open-air parking lots, public squares and other public places and is a novel environmental protection low-carbon material.

Description

technical field [0001] The invention relates to a method for preparing permeable bricks by using sugar filter mud waste from sugar factories as a pore-forming agent, relates to the field of sewage treatment, and belongs to the field of resources and environment. Background technique [0002] At present, my country attaches great importance to energy saving, consumption reduction and pollution reduction, and has taken energy saving and emission reduction as an important strategy for national development. At present, impermeable materials such as marble, cement and asphalt are mainly used in urban construction to pave squares and sidewalks. Though the pavement that adopts above-mentioned material laying has neat and tidy effect, also has some shortcomings. The first is to affect the urban drainage system. Due to the poor water permeability of these materials, when it rains, it prevents the infiltration of rainwater, resulting in the lack of replenishment of urban groundwater ...
