Present existing artificial sand production line, the overwhelming majority adopts the wet method producing process, in the tradition artificial sand wet method processing technology, artificial sand wash mud, screw sand washer is adopted in dehydration, the artificial sand especially loss of fine sand almost can not be controlled, and it is serious that its shortcoming is that the fine sand of granularity below 0.16mm runs off, have in addition surpass more than 20%, cause grating unreasonable, modulus of fineness is thick partially.
The utility model content
Problem to be solved in the utility model just provides a kind of novel structure, uniqueness, fine sand retracting device stably turns round, not only improved the ability of equipment recovery fine sand, can effectively reduce the number of dropouts of fine sand, it is controlled within 5~10%, and has solved the difficult problem that the finished sand modulus of fineness is thick partially, content of stone powder is on the low side that the artificial aggregate system of processing occurs well.
In order to solve the problems of the technologies described above, the utility model adopts following technical scheme: a kind of fine sand retracting device, it is characterized in that: comprise support, and the material storing box and the returning charge case that stores mortar after centrifugal classification that are located at storage sewage on the support respectively, the material storing box top is provided with the sand water separation device, the returning charge case is provided with cyclone, the front end exit of cyclone is located at sand water separation device top, the back outlet of cyclone is communicated with the returning charge case, below cyclone, also be provided with the slag pulp grinder of carrying mortar, the slag pulp grinder is provided with the upper end that conveyance conduit is communicated to cyclone by motor-driven on the slag pulp grinder.
Further, described sand water separation device comprises the vibratory sieve that is located at the material storing box top, and the front end exit of cyclone is provided with the sand setting mouth and is fixed on the front upper of vibratory sieve by the sand setting mouth.Fine sand is effectively separated with water.
Further, described vibratory sieve is a linear vibrating screen, and the screen cloth of vibratory sieve is a polyurethane screen.Polyurethane screen is longer than other type screen life-span, and is difficult for plug-hole.
Further, described cyclone inside is provided with the polyurethane liner.Adopt the polyurethane liner, in the service life of having improved cyclone, can finish work such as slip concentrates, liquid clarification smoothly.
Further, described returning charge case is provided with drainpipe and is communicated with material storing box.A small amount of fine sand, mud etc. return material storing box through the returning charge case.
Further, the water intake end of described drainpipe is located at the bottom of returning charge case, and the water side of drainpipe is located at the top of material storing box, and water intake end is higher than the water side.
Further, described slag pulp grinder is provided with water inlet pipe and is communicated with material storing box.Sewage in the available material storing box is regulated pulp consistency in the slag pulp grinder, increases the utilization rate of resource.
Further, described material storing box top is provided with overfall.When liquid level is too high in the material storing box, discharge through overfall.
After adopting technique scheme, the utlity model has following advantage: can effectively reduce the number of dropouts of fine sand, it is controlled within 5~10%.Solved the difficult problem that the finished sand modulus of fineness is thick partially, content of stone powder is on the low side that the artificial aggregate system of processing occurs well; 85% fine granular materials has unrivaled technology of other equipment and economic advantages in the maximum recyclable total emission volumn.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing:
Fig. 1 is the structural representation of a kind of embodiment of the utility model;
Fig. 2 is a vertical view embodiment illustrated in fig. 1.
The specific embodiment
The structural representation of a kind of embodiment of the utility model shown in Fig. 1 to 2, a kind of fine sand retracting device, comprise support 1, and the material storing box 2 and the returning charge case 3 that stores mortar after centrifugal classification that are located at storage sewage on the support respectively, material storing box top is provided with overfall 21, and the returning charge case is provided with drainpipe 31 and is communicated with material storing box, and the water intake end of drainpipe is located at the bottom of returning charge case, the water side of drainpipe is located at the top of material storing box, and water intake end is higher than the water side; The material storing box top is provided with sand water separation device 4, and the returning charge case is provided with cyclone 5, and the front end exit 51 of cyclone is located at sand water separation device top, and the back outlet 52 of cyclone is communicated with the returning charge case, is provided with the polyurethane liner in cyclone inside; Also be provided with the slag pulp grinder 6 of carrying mortar below cyclone, the slag pulp grinder is driven by motor 7, is provided with the upper end that conveyance conduit 61 is communicated to cyclone on the slag pulp grinder, and the slag pulp grinder is provided with water inlet pipe 62 and is communicated with material storing box; Described sand water separation device comprises the vibratory sieve that is located at material storing box top, and the front end exit of cyclone is provided with sand setting mouth 53 and is fixed on the front upper of vibratory sieve by the sand setting mouth, and described vibratory sieve is a linear vibrating screen, and the screen cloth of vibratory sieve is a polyurethane screen.
The utility model can adopt bi-motor, two slag pulp grinder, double cyclones to assemble side by side, has improved the ability of equipment recovery fine sand.Operation principle of the present utility model is: the slag pulp grinder is that mortar is delivered to cyclone with the sand aqueous mixtures, the fine sand that concentrates through centrifugal classification arrives linear vibrating screen by the sand setting mouth, after the vibratory sieve dehydration, fine sand effectively separates with water, inflow returning charge case such as a small amount of fine sand, muddy water also returns material storing box, thereby finishes cleaning, dehydration and three kinds of functions of classification.When the material storing box liquid level is too high, discharge through overfall.Linear vibrating screen recovered material weight concentration is 70%---85%, and regulating modulus of fineness can be by changing revolution speed, change pulp consistency, regulates the overflow water yield, changing the mouth that shakes out and realize.
