Because this dry mortar mixing plant has the corresponding technique effect of above-mentioned screening crushing system, repeat no more.
Accompanying drawing explanation
The accompanying drawing that forms a part of the present invention is used to provide a further understanding of the present invention, and schematic description and description of the present invention is used for explaining the present invention, does not form inappropriate limitation of the present invention.In the accompanying drawings:
Fig. 1 is the screening crushing system structural representation of existing dry mortar mixing plant; For convenience of understanding, in Fig. 1, also show other component structures of dry mortar mixing plant;
The structural representation of the dry mortar mixing plant that Fig. 2 provides for the embodiment of the present invention; For convenience of understanding, in Fig. 2, also show other component structures of dry mortar mixing plant.
The specific embodiment
It should be noted that, in the situation that not conflicting, embodiment and the feature in embodiment in the present invention can combine mutually.Describe below with reference to the accompanying drawings and in conjunction with the embodiments the present invention in detail.
The structural representation of the screening crushing system of the dry mortar mixing plant that Fig. 2 provides for the embodiment of the present invention; As shown in Figure 2, the screening crushing system of dry mortar mixing plant comprises: dry sand elevator 2, for receiving the vibratory sieve 3 of the sand material of dry sand elevator 2 output, for depositing at least two storage warehouses of the sand material of vibratory sieve 3 outputs, the first storage warehouse 12 at least two storage warehouses is for depositing fine sand, the second storage warehouse at least two storage warehouses is for depositing the sand material that particle diameter is greater than fine sand, and the screening crushing system of this dry mortar mixing plant also comprises: valve (scheming not shown), passage, disintegrating machine 10 and feed back pipe 11; The upper end of passage connects the second storage silo (positions such as discharging opening, bulkhead, cone bucket that specifically can connect the second storage silo), and the upper end of passage is also provided with valve, and the lower end of passage connects the charging aperture of disintegrating machine 10; The upper end of feed back pipe 11 connects the discharging opening of disintegrating machine 10, and dock with the charging aperture of dry sand elevator 2 lower end of feed back pipe 11.
During concrete operations, the quantity of the second storage warehouse is at least two, be respectively used to deposit the sand material of different-grain diameter (as two kinds in waste material, medium sand, coarse sand, certainly the sand material that is greater than fine sand can be divided into more grade, as 4 grades or more), the quantity of valve and passage is consistent with the quantity of at least two the second storage warehouses, valve and passage and the corresponding setting one by one of at least two the second storage warehouses; Particularly, as shown in Figure 2 three, the second storage warehouse 6 is for depositing antiquated sand, and the second storage warehouse 5 is for depositing coarse sand, and the second storage warehouse 4 is for depositing medium sand; The quantity of valve and passage is three, and wherein the upper end of passage 7 connects the discharging opening of the second storage silo 6, and the upper end of passage 7 is also provided with valve (scheming not shown), and the lower end of passage 7 connects the charging aperture of disintegrating machine 10; The upper end of passage 8 connects the discharging opening of the second storage silo 5, and the upper end of passage 8 is also provided with valve (scheming not shown), and the lower end of passage 8 connects the charging aperture of disintegrating machine 10; The upper end of passage 9 connects the discharging opening of the second storage silo 4, and the upper end of passage 9 is also provided with valve (scheming not shown), and the lower end of passage 9 connects the charging aperture of disintegrating machine 10.Correspondingly, vibratory sieve 3 is three-deck vibrating screen, so that sand material is divided into fine sand, medium sand, coarse sand and waste material.Be understandable that, separate as required other difference of level of sand material, the number of plies of vibratory sieve 3 is corresponding change also.While being greater than the sand material of fine sand as sand material being divided into fine sand and particle diameter, the number of plies of vibratory sieve 3 can be one deck; When the sand material that is greater than fine sand is divided into more grade, during as 4 grade, the number of plies of vibratory sieve 3 can be four layers.
The course of work of the screening crushing system of above-mentioned dry mortar mixing plant is summarized as follows: when vibratory sieve 3 sieves out waste material, waste material stores in the second storage silo 6, waste material promotes by dry sand elevator 2 after disintegrating machine 10 fragmentations, enters the vibratory sieve 3 rear storages of screening (being stored in each storage silo according to the particle diameter after fragmentation); When the medium sand in the second storage warehouse 4 or the coarse sand material in the second storage warehouse completely need flash, open the valve on passage, make coarse sand or medium sand generate fine sand after disintegrating machine 10 fragmentations, after promoting by dry sand elevator 2, enter rear storage of vibratory sieve 3 screenings, thereby prevent flash.
The present invention carries out fragmentation by the sand material after utilizing disintegrating machine to screening, can utilize for waste material, can also avoid medium sand, the frequent flash of coarse sand storage warehouse to cause raw material to pile up waste, prevents the environmental pollution that waste material, flash and transhipment cause; Meanwhile, by the broken of sand material and recycle, can realize (the sand material of various particle diameters) the at different levels proportioning in sand source is adjusted, than existing dry mortar mixing plant, can reduce one for screening out the elementary vibratory sieve of waste material, cost-saving.
The present invention also provides a kind of embodiment of dry mortar mixing plant, and it is provided with above-mentioned screening crushing system, and can there be various ways in its ,Gai mechanism of mechanism that can also be included as dry sand elevator 2 charging aperture feed:
The first: dry mortar mixing plant also comprises drying system 1, the discharging opening of drying system 1 docks with the charging aperture of dry sand elevator 2.Now, dock with the discharging opening of drying system 1 lower end that feed back pipe 11 also can be set, so that the sand material after fragmentation is recycled.
