Recovery production device for construction waste added as barren material for brick sintering

Abstract

The invention discloses a recovery production device for construction waste added as a barren material for brick sintering, and relates to the technical field of waste recovery. To solve the problem that an existing crushing device cannot meet the requirement for complete crushing at a time, and the processes of later screening and re-crushing are added, the following scheme is proposed. The recovery production device comprises a crushing mechanism, a driving mechanism, a screening mechanism and a grinding mechanism, wherein the crushing mechanism, the screening mechanism and the grinding mechanism are all under driving control of the driving mechanism; and the screening mechanism comprises a fixing box, the bottom box wall of the fixing box is fixedly sleeved with a screen, the right boxwall of the fixing box is movably sleeved with a movable frame, and the right outer wall of the fixing box is connected with a push-and-pull mechanism fixedly connected with the movable frame. The recovery production device not only facilitates repeated crushing of raw materials, but also performs screening simultaneously during crushing, which is beneficial to the quality of final crushing; and besides, the whole device adopts the same motor for driving control, the degree of integration is high, and the market competitiveness of the device is improved.

Description

technical field [0001] The invention relates to the technical field of garbage recycling, in particular to construction garbage recycling production equipment for brick sintering added as barren materials. Background technique [0002] There will be a lot of garbage resources in the building that have not been processed, which will cause a great waste of resources. For example, the demolition waste of red bricks and tiles produced in construction is red, finely broken and blocky, with a loose dry density of 1360 kg / m 3 , no calorific value, no plasticity, it can be added as a barren material for brick sintering. Since most of the brick-making raw materials are aluminosilicate raw materials, the chemical composition mainly includes silicon dioxide (SiO 2 ) and aluminum oxide (Al 2 o 3 ), and depending on the production conditions, it also contains a small amount of alkali metal and alkaline earth metal oxides, such as: iron oxide (Fe 2 o 3 ), calcium oxide (CaO), magnes...

AI Technical Summary

Problems solved by technology

[0003] However, there is currently no processing equipment specially used to deal with demolition waste such as red bricks on the market, especially when these red bricks are recycled and utilized, they need to be crushed. However, the crushing efficiency of the existing crushing equipment is low and cannot be crushed at one time. Requirements, it is easy to have incomplete crushing, which increases the process of later screening and re-crushing of a large number of raw materials. For this reason, we propose a construction waste recycling production equipment for brick sintering that is added as a barren material.
