Embodiment 1

[0057] A sintered brick preparation process includes the steps of raw material crushing-powder screening-aging treatment-green body forming-wet green body drying-finished product roasting and the like.

[0058] Raw material pulverization steps: Take, for example, 45% of cinder, 20% of clay, 5% of coal gangue, 15% of fly ash, 5% of cement, and 5% of sodium silicate, and pulverize them into powders with the same particle size through a pulverizer to obtain the first mixing powder.

[0059] Powder screening: pass the prepared mixed powder into the screening device for screening. The sieving is divided into three sections, the first section is the primary screening of the mixed powder with larger particles, the second section is the secondary screening of the mixed powder coarse material, and the third section sieving the first The fine materials obtained after the stage screening and the second stage screening are collected and screened again through the metal separation equipme...

Embodiment 2

[0065] Such as figure 1 As shown, a dedicated aging warehouse for the preparation process of sintered bricks includes an aging warehouse 1 , a feeding conveyor belt 2 , a discharging conveyor belt 3 , and a hoist 4 . The aging warehouse 1 is formed by two low walls, and one of the walls is provided with a leaning plate against the wall, which is used for leaning on the stacked mixture. The top of the aging bin 1 is the feeding conveying belt 2 , the side is the discharging conveying belt 3 , and the outside of the discharging conveying belt 3 is the elevator 4 . The aging bin 1 is provided with a temperature and humidity monitoring system 5 and a number of detection bins 6 preset at the bottom of the aging bin 1, and stores the mixture to be aged, wherein the mixture surrounds the detection bin 6 to provide a humidity environment for the detection bin 6 . In this way, the improved aging warehouse can monitor the temperature and humidity of the aged mixture in real time, so a...

Abstract

The invention relates to the technical field of sintered bricks, in particular to a sintered brick preparation process and a special ageing silo. The sintered brick preparation process comprises the steps of raw material smashing, powder screening, ageing treatment, blank forming, wet blank drying and finished product roasting, wherein powder screening is conducted, specifically, prepared mixed powder is introduced into a screening device to be screened, the screened powder is conveyed to the next step, and the large-particle mixed powder after screening is circularly conveyed to the raw material smashing step again. The special ageing silo comprises an ageing bin, a feeding conveying belt, a discharging conveying belt and an elevator, wherein the ageing bin is internally provided with a temperature and humidity monitoring system and a plurality of detection bins pre-arranged at the bottom of the ageing bin. According to the sintered brick preparation process and the special ageing silo, the respective particle moisture of raw materials is promoted to be uniform and consistent, the ageing time is convenient to control, and during ageing, particles can meet the requirement for the minimum moisture content in the same period so as to save the ageing time.

Description

technical field [0001] The invention relates to the technical field of sintered bricks, more specifically, it relates to a preparation process of sintered bricks and a special aging storage. Background technique [0002] Generally speaking, the process of sintered bricks consists of four parts: raw material preparation, body molding, wet body drying and finished product firing. After the brick-making raw materials are excavated, some raw materials can be processed by adding water, stirring and grinding equipment, while some raw materials cannot. Raw materials such as mountain soil, coal gangue and shale still need to be crushed and finely crushed, then mixed with water and milled. The selection and preparation of raw materials directly affect the quality of finished bricks. [0003] The Chinese patent with the notification number CN106278169A discloses a method for preparing sintered bricks, which includes crushing ingredients, extruding billets, high-temperature roasting,...
