The layout of the equipment of the mortar production line that the present embodiment provides can be divided into tower with standing posture two kinds of patterns.As shown in figure 12, tower dry powder mortar production line is also known as a stepwise mortar production line, and design mortar raw material (except the dry sand that consumption is maximum) is all pre-stored in main building top, and material is from top to bottom through metering, mixing, finished product preservation and packaging.The maximum feature of this form is that Flow of Goods and Materials is smooth and easy, and the succinct floor space of equipment is relatively little.Powder material is by Geldart-D particle, and dry sand is sent in storehouse by bucket elevator; With conveying worm material feeding is arranged on bottom raw material cabin in the weighing hopper under warehouse and weighs, then enter mixer and mix.The mortar product mixed enters packaging or bulk system respectively.In bulkly directly can enter bulk vehicle through bulk machine, also again can rise to the entrucking again of finished product warehouse.Packaged unit is that mortar is introduced into all roll-overs of packaging, then is packaged into bag through packing machine.
Equipment mainly configure comprise storage, metering, mixing, packaging, in bulk, gather dust and the system such as control automatically, except dry sand storage tank, other equipment all adopt the mode of longitudinal stack to arrange, highly general about 27 meters.Due to height and raw material storage amount, steel construction partial amount is larger, and thus cost is relatively large.
As shown in figure 13, the dry powder mortar production line of standing posture layout is that raw material warehouse is moved to ground above mixer, thus arranges also referred to as two rank.Powder storage warehouse is placed on the side of the main building installing mixer, the main building top that additive storehouse and sand week roll-over are placed, and raw material metering is arranged on above mixer.Cement and flyash are measured to raw material from storage warehouse conveyer by spiral, and dry sand first sends into bucket elevator by belt feeder, then by machine bucket elevator second lift to sand meter.Metering is the same with tower layout afterwards enters mixing, bag/in bulk.
Standing posture layout dry powder mortar production line, powder material to put in storage storage through Geldart-D particle equally, arranged apart with main building due to height reduction, reduces load capacity and the main building construction height of main building steel construction, thus can reduce construction investment.The design parameter difference of two kinds of layouts is as shown in table 1.
