Embodiment

[0057] This embodiment is a method for matching and adjusting the forming parameters of the production line of 200 million pieces (fly ash autoclaved standard bricks). (Based on the annual brick machine production rate of 91.2%, the output is 25,000 pieces / hour)

[0058] Ⅰ Raw material preparation and dry raw material ratio before dry raw material ratio

[0059] The following a, b, c are raw material preparations before production

[0060] a The standard requirements for technical indicators of quicklime entering the factory: effective CaO content ≥ 58%, digestion time: 8-12 minutes, digestion temperature: 50-60 degrees.

[0061] b The first stage of quicklime crushing adopts a jaw crusher, the gap between the jaw plates is 6-10mm, and the second stage crusher adopts a ball mill, and the grinding time in the ball mill is 3 minutes.

[0062] c The water content of the furnace bottom coarse slag entering the factory: 20-24%, and the large particles ≥ 5mm are screened out befor...

Abstract

The invention relates to a method for adjusting the matching degree of forming parameters of a coal ash autoclaved standard brick. The adjusted parameters comprise the following important parameters including dry raw material ratio, feeding door opening time, material distributing bed moving speed and rocking bar swinging times, wherein I, the dry raw materials comprises the following components in parts by mass: 46 to 50 parts of coal ash, 7 to 9 parts of quick lime, 3.6 to 4.4 parts of dust-removing lime, 20 to 24 parts of gravel and 16 to 20 parts of coarse slag, wherein the granularity of the gravel is less than or equal to 5 mm and 9.4 to 10 percent of water is added into the dry materials; II, the feeding door opening time is controlled to be 0.1 to 0.3 second; III, the rated value of the material distributing bed moving speed is 1.8 to 2.2 m / s and the normal set value is 70 to 80 percent of the rated value; IV, technical parameters of material distribution are controlled, i.e., a rocking bar swings for 5 to 6 times and a mould frame charging depth is 220 mm. By adopting the method for adjusting the matching degree of the forming parameters of the coal ash autoclaved standard brick, the blank formation qualified ratio of manufactured standard bricks is high.

Description

technical field [0001] The invention relates to a method for matching and adjusting forming parameters of fly ash autoclaved standard bricks. Background technique [0002] Fly ash autoclaved standard brick is a new type of energy-saving building material, and it is also a substitute for ordinary clay bricks (ie red bricks). In the production process of fly ash autoclaved standard bricks, processes such as raw material processing and preparation, metering and batching, water mixing, digestion and heat release, hydraulic forming, and steam autoclaving operations are involved. Among them, many kinds of production process technical parameters are adjusted and controlled, including: fly ash loss on ignition, fly ash particle size, moisture content of mixture, quicklime digestion time, effective CaO content out of the warehouse, cloth distribution times and charging depth, forming pre-production pressure etc. Forming parameters play a decisive role in the quality and output of f...
