The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of process units of EPS beads-mixed lightweight soil is provided, and has realized that the continuous metering of EPS particle feeds intake.
Technical scheme: the utility model comprises foaming machine, cooling device, first centrifugal blower, second centrifugal blower, storage bin, butterfly valve and conveying worm; Wherein: foaming machine links to each other with cooling device, first centrifugal blower is arranged between foaming machine and the cooling device, cooling device links to each other by pipeline with storage bin, second centrifugal blower is arranged between cooling device and the storage bin, the bottom discharge mouth of storage bin links to each other with butterfly valve, and the discharging opening of butterfly valve links to each other with the charging aperture of conveying worm.
Described cooling device is the pouch that nylon gauze is made, and described pouch links to each other by pipeline with storage bin.
Described storage bin is the blade inserting assembly unit case of steel construction, and is simple in structure, easy for installation.
The casing upper and lower of described storage bin all is provided with the material level besel, is used to monitor the storage of EPS particle in the storage bin.
The top material level besel of described storage bin is provided with filter screen, so that get rid of the gas that centrifugal blower brings.
The discharging opening of the bottom of described storage bin is an infundibulate, is convenient to discharging and flow-control.
Beneficial effect: the utility model has the following advantages compared to existing technology, the utility model utilizes the transformation of Stabilized Soil blending station to form, feed intake owing to adopted the EPS storage bin of large volume and the EPS particle measured, productivity ratio has been had to significantly improve, per hour the output of mix light-textured soil can reach 300 tons (adopt the concrete mixer output be the 50-60 ton/hour), fully satisfied the uninterrupted continuous generous amount construction demand in job site, operation control is easier accurately, reduced the labour, equipment operation and construction cost have been reduced, because the full whipping process of producing all adopts closed type, reduced pollution simultaneously to surrounding environment.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the partial schematic diagram of the utility model storage bin.
The specific embodiment
Below embodiment of the present utility model is elaborated; present embodiment is being to implement under the prerequisite with technical solutions of the utility model; provided detailed embodiment and concrete operating process, but protection domain of the present utility model is not limited to following embodiment.
As depicted in figs. 1 and 2, present embodiment comprises pouch 9, first centrifugal blower 10, second centrifugal blower 11, storage bin 12, butterfly valve 13 and the conveying worm 14 that raw material soil batch bin 1, water tank 2, cementing tank 3, belt conveyor 4, mixer 5, finished bin 6, control room 7, foaming machine 8, nylon gauze are made; Foaming machine 8 links to each other with pouch 9, first centrifugal blower 10 is arranged between foaming machine 8 and the pouch 9, pouch 9 and storage bin 12 link to each other by pipeline, second centrifugal blower 11 is arranged between pouch 9 and the storage bin 12, the bottom discharge mouth of storage bin 12 links to each other with butterfly valve 13, and the discharging opening of butterfly valve 13 links to each other with the charging aperture of conveying worm 14.
Earlier the EPS raw material is foamed into equal-sized spheric granules, and, cooled off 2 hours, allow particle fully expand by first centrifugal blower, 10 input pouch 9 by foaming machine 8 (model EPS-4300), in stable condition, and control heap side density is at 12-15KG/m
3In the scope, the good EPS particle that will foam again is transported in the storage bin 12 by second centrifugal blower 11.
The discharging opening of butterfly valve 13 is connected with the charging aperture of conveying worm 14, the EPS particle arrives conveying worm 14 through the discharging opening of storage bin 12 again to butterfly valve 13 during production, enter mixer 5 at last, can realize continuously the uninterrupted production of stirring, and with raw material soil according to the design the volume ratio continuous stirring, add a certain amount of cement and water simultaneously and stir into mix light-textured soil.
The model of the conveying worm 14 that present embodiment adopts is the LSY250 type, power 11KW, length 6500mm, 26 ° of established angles, maximum delivery 46.8m
3/ h.The conveying capacity of screw machine is controlled by frequency converter, promptly changes the input quantity that the screw machine rotating speed of motor is controlled the EPS particle, that is to say to reach a stable match ratio, and the FREQUENCY CONTROL that will make motor is in a constant value.
When producing, can configure some parameters in advance by experiment, be different frequency the volume of corresponding different EPS particle transport, to satisfy the needs that the job site produces, at first calculate heap side's density of EPS particle, the quality (frequency setting) of the EPS particle of carrying in the unit of account time is then extrapolated volume with the quality of the EPS particle carried in the unit interval again.
