Description
Technical field
The present invention relates to a kind of dry sand storehouse, belong to anti-maceration technique field, dry-mixed mortar plant dry sand storehouse, especially a kind of anti-segregation dry sand storehouse and method.
Background technology
At present, in dry-mixed mortar plant, for depositing the storage silo of dry sand, mainly adopted vertical drop formula structure, make the dry sand after drying directly fall within storehouse, because the inside drop in storehouse is larger, and the proportion of different-grain diameter (0-5mm) dry sand material is different, speed during free fall is different, in storing banking process, dry sand self-assembling formation is cone-shaped, compared with the dry sand material of fine grain, with cone, naturally up pile up, and relatively coarse grain footpath dry sand material from cone surrounding naturally down during landing, very easily produce secondary separation, " segregation " phenomenon that causes dry sand, make from the blowing process of sand storehouse thick, thin dry sand material flows out respectively, affect the quality of finished product dry-mixed mortar.In addition, because making the dry sand that is previously temporarily stored in bottom, storehouse, the dry sand material of free fall is further compacted, cause the discharging of dry sand bin discharge port external clean, have some setbacks, bring adverse effect to the normal use in dry sand storehouse, even shorten its service life, the aging speed of quickening equipment, causes the increase of productive costs.
Summary of the invention
The object of the invention is to overcome the weak point in prior art, a kind of anti-segregation dry sand storehouse and method are provided.This anti-segregation dry sand storehouse effectively avoids dry sand in flowing into storehouse internal procedure, to produce segregation, and realizes the integral body whereabouts of dry sand material in the blowing process of dry sand storehouse, falls clean, smooth and easy, saves productive costs, guarantees the quality of mortar product.
For achieving the above object, technical solution of the present invention is: a kind of anti-segregation dry sand storehouse comprises feed bin and isolation-proof device.Described feed bin comprises feed chute, feeder hopper, warehouse and dispensing valve, and feed chute is fixed on the top cover plate of warehouse, and outlet and the feeder hopper of feed chute connect; Warehouse mainly comprises the cylinder on top and the conic tube of bottom, and for to guarantee the smooth and easy of blowing, the coning angle δ of conic tube is made as to 60 ° ~ 65 °; Dispensing valve is arranged on the discharge nozzle of warehouse lower end.
Described isolation-proof device comprises a supervisor and many lateral canals; Supervisor is tetragonal square tube for cross section, is fixed on the inside of warehouse by upper bracket and lower bracket, and makes to be responsible for upper end and feeder hopper connects, and lower end is unsettled, and the vertical distance that makes to be responsible between lower end and dispensing valve remains between 1000 ~ 1200mm; On four side plates of supervisor, all have the discharging opening of equal number, the certain distance that mutually evenly staggers in the vertical direction of the discharging opening on four side plates, makes the center-point of each discharging opening be evenly distributed on one on the helix line of supervisor's inscribed circle cylindrical shell; In discharging opening on four side plates, all at one or two discharging opening places, side pipe is installed, each side pipe tilts to install, and side pipe relatively supervisor's inclination angle beta is 40 ° ~ 50 °, and the relative supervisor's of bottom side pipe angle of inclination is greater than the angle of inclination of top side pipe.
On four side plates of described supervisor, can have the discharging opening of 4 ~ 8.
Described upper bracket and lower bracket be square or cylindrical shape strut bar composition by four; When adopting square strut bar, for reducing the mobile resistance shelves of sand material, must make when mounted four sides that form strut bar be symmetrical heeling condition; The two ends of strut bar are separately fixed on the inwall of supervisor and warehouse, and for to reduce the mobile impact of sand material as far as possible, four strut bars of upper bracket are the symmetry state that is inclined upwardly, strut bar is 45 ° ~ 50 ° with the folded sharp angle α of supervisor's line of centers, and four strut bars of lower bracket are symmetrical downward-sloping state, strut bar is 50 ° ~ 55 ° with the folded acute angle gamma of supervisor's line of centers.
For achieving the above object, the present invention separately provides the method in a kind of anti-segregation dry sand storehouse, comprising: the dry sand material of having been dried, through feed chute, feeder hopper and isolation-proof device, is wandered to feed bin; Dry sand material, in dropping process, is subject to the friction drag effect of feeder hopper, supervisor and side pipe inside face, and dropping process slows down, and reduces the follow-up dry sand material entering to being first advanced into the impact degree of dry sand material in storehouse; Meanwhile, by the discharging opening on supervisor and the effect of side pipe, make dry sand material whereabouts flow process obtain regular constraint, the irregular diffusion of having avoided original free fall to form, thus effectively avoided the process of dry sand material in falling into storehouse to emanate.When opening dispensing valve enforcement blowing, whole isolation-proof device can make dry sand material obviously reduced by the degree of laterally extruding, the integral body that realizes dry sand material falls, and guarantees to fall clean, smooth and easy, avoids occurring the phenomenon that coarse fodder and fines flow out respectively.
Owing to adopting technique scheme, the invention has the beneficial effects as follows: on isolation-proof device supervisor, be provided with a plurality of discharging openings of cloth in the shape of a spiral, and be provided with a plurality of side pipes by the inclined at inclination angles of tribology principle design, and the optimization to warehouse bottom conic tube coning angle based on tribology principle, can effectively avoid dry sand material segregation phenomenon to occur depositing to the process in storehouse, and dry sand material suffered horizontal extruding degree in blowing process is obviously reduced, avoid the generation of segregation phenomenon and the phenomenon that falls to having some setbacks etc. in blowing process; Optimization by the shape of upper and lower frame support rails and installation site etc., can reduce the suffered flow barrier degree of dry sand material in blowing process to greatest extent.It is simple in structure, and anti-segregation is effective, and reliability of service is high, can effectively improve mortar product quality, has practicality widely.
