Embodiment 1

[0031] The purpose of the present invention is to process aerated concrete waste such as scraps removed in the cutting process in the aerated concrete slab and block production line, and waste generated by truncating unrepairable aerated concrete slabs and blocks. Reduce pollution and land occupation caused by waste aerated concrete.

[0032] combined with figure 1 As shown, the processing method uses the comprehensive utilization system of aerated concrete waste, including a double-shaft metal crusher 1, a ring hammer European-style crusher 2, a transition bin 3 and a pouring mixer 4.

[0033] The discharge port of the double-shaft metal crusher 1 is connected to the feed port of the European version of the ring hammer crusher 2, and a filter screen (not shown in the figure) is arranged inside the ring hammer crusher 2, and the mesh diameter of the filter screen is 1.2mm, so as to control the diameter of the waste after crushing; the discharge port of the ring hammer Europea...

[0040] The purpose of the present invention is to process aerated concrete waste such as scraps removed in the cutting process in the aerated concrete slab and block production line, and waste generated by truncating unrepairable aerated concrete slabs and blocks. Reduce pollution and land occupation caused by waste aerated concrete.

[0041] combined with figure 1 As shown, the processing method uses the comprehensive utilization system of aerated concrete waste, including a double-shaft metal crusher 1, a ring hammer European-style crusher 2, a transition bin 3 and a pouring mixer 4.

[0042] The discharge port of the double-shaft metal crusher 1 is connected to the feed port of the European version of the ring hammer crusher 2, and a filter screen (not shown in the figure) is arranged inside the ring hammer crusher 2, and the mesh diameter of the filter screen is 1.0mm, so as to control the diameter of the waste after crushing; the discharge port of the ring hammer Europea...

Embodiment 3

[0049] The purpose of the present invention is to process aerated concrete waste such as scraps removed in the cutting process in the aerated concrete slab and block production line, and waste generated by truncating unrepairable aerated concrete slabs and blocks. Reduce pollution and land occupation caused by waste aerated concrete.

[0050] combined with figure 1 As shown, the processing method uses the comprehensive utilization system of aerated concrete waste, including a double-shaft metal crusher 1, a ring hammer European-style crusher 2, a transition bin 3 and a pouring mixer 4.

[0051] The discharge port of the double-shaft metal crusher 1 is connected to the feed port of the European version of the ring hammer crusher 2, and a filter screen (not shown in the figure) is arranged inside the ring hammer crusher 2, and the mesh diameter of the filter screen is 0.6mm, so as to control the diameter of the waste after crushing; the discharge port of the ring hammer Europea...

Abstract

The invention relates to an aerated concrete waste comprehensive utilization method and system. The system and the method are characterized in that the system comprises a double-shaft metal crusher, aring hammer European style crusher, a transition bin and a pouring stirrer; waste is crushed through the double-shaft metal crusher and the ring hammer European style crusher to allow the diameter ofthe waste to range from 0.2 mm to 1 mm; the crushed waste is conveyed into the transition bin of a pouring building through a pneumatic conveyor to be temporarily stored; in the next aerated concreteplate or building block production process, the waste is used as aggregate to be doped into an aerated concrete mixture composed of sand, fly ash, silicon-containing tailings, lime, cement, a foamingagent and water, the mixture is stirred in the pouring stirrer, and the mass of the waste accounts for 3%-8% of the mass of the aerated concrete mixture. The aerated concrete waste can be treated, and the occupied area and pollution of the waste are reduced; the waste is doped into concrete for subsequent production as aggregate, so that the consumption of lime and cement is reduced; waste treatment energy consumption is low, and the cost is saved.

Description

technical field [0001] The invention belongs to the field of aerated concrete waste treatment, in particular to a comprehensive utilization method and system for aerated concrete waste. Background technique [0002] Traditional aerated concrete material production factories have piled up waste materials that cannot be efficiently disposed of, not only causing pollution but also occupying land. In order to solve the above problems, some aerated concrete material production plants have processed and reused waste materials. At present, there are two common waste utilization production lines and process planning schemes as follows: [0003] The first category is the board waste recycling system and recycling method disclosed in CN 110090718 A. The method includes the following steps: crushing the waste scraps and unqualified boards through a crusher to form irregular blocks with a length of no more than 100mm Plates; transport the preliminarily crushed waste to the tank of the ...
