Description

High discharge device for loose unpacked material
(1) technical field
The present invention relates to a kind of high discharge device for loose unpacked material.Be used for the dry state loose unpacked material that has certain flowing power with a kind of, be discharged in the predetermined warehouse from tens meters eminences.Belong to the load transfer device technical field.
(2) background technology
Along with development of economic construction, add the dry mortar that raw material mixes by cement, sand and multiple trace, be widely used as a kind of energy-conserving and environment-protective material of building industry.The containerization of dry mortar is the inexorable trend of building a resource-conserving society, protecting city environment, reduction building cost, promote the dry-mixed mortar application.But in present dry-mixed mortar production plant, because the segregation problem of dry mortar has limited the development of dry-mixed mortar containerization.The reason that produces segregation is:
In the time of the discharging of a loose unpacked material high position, the various materials in the compound are in free falling body state basically, because the difference of the various materials in the mixed material, according to the acceleration due to gravity principle, quality is big more, and acceleration/accel is big more, falling speed is just fast more, and the falling speed that quality is little is just slow.In the dry mortar, the quality of sand is bigger, and cement, additive all are powderies, and granularity is very little, and quality is less, and their falling speed difference is very big, is very easy to form segregation.
(3) summary of the invention
The objective of the invention is to overcome above-mentioned deficiency, provide a kind of and can limit and eliminate the free falling body state of various materials, thereby reduce and eliminate the high discharge device for loose unpacked material of segregation effectively.
The object of the present invention is achieved like this: a kind of high discharge device for loose unpacked material, comprise transition feed bin, tapering transition hopper, storehouse in bulk and discharge duct, described transition feed bin bottom device has the tapering transition hopper, described storehouse in bulk is arranged at tapering transition hopper below, described discharge duct is arranged in the storehouse in bulk, the upper end of this discharge duct links to each other with the discharging opening of tapering transition hopper, the lower end is arranged in the storehouse in bulk, laterally offer several dumping pits on the described discharge duct, arrange but discharge duct can be arranged vertically also the aperture certain angle that is inclined upwardly in storehouse in bulk.
High discharge device for loose unpacked material of the present invention is arranged with Charge level measurer and following Charge level measurer up and down in parallel in the described transition feed bin, transition feed bin bottom device has the discharging control sluice.
High discharge device for loose unpacked material of the present invention, described discharge duct constitutes by some joint discharge ducts are end to end, and wherein final section discharge duct upper end is provided with flange, and the lower end is uncovered, and all the other respectively save discharge duct and all are provided with flange in two ends up and down.
In each cyclic process of dry mortar discharging from discharge duct, except that a small amount of material of bottommost is in the free falling body state, remaining material all forms squeezed state in discharge duct, fwd is keeping off the back, the back pushing away fwd, constrained each other, synchronize them discharging, can not form free-falling body, also just controlled the material segregation.Mixture has guaranteed to enter the maximum density of material in the discharge duct by transition hopper, thereby has reduced the probability of material free-falling body, has controlled the material segregation effectively.This discharge way reduces to greatest extent and controls material segregation, has guaranteed the product design of dry mortar in bulk, has also just guaranteed the building operation quality.
The present invention is simple in structure, convenient for installation and maintenance, use is reliable.Solved material segregation problem serious in the high-order discharge process of bulk blend material.Be applicable to that by multiple different densities the high-order discharging of the different-grain diameter mixture that particularly material density gap and proportioning gap are bigger reaches the purpose that actv. prevents material segregation in the high-order discharge process.

(5) specific embodiment
Referring to Fig. 1, the high discharge device for loose unpacked material that the present invention relates to mainly is made up of transition feed bin 5, tapering transition hopper 9, storehouse in bulk 4, discharge duct 10 and automatic control device 11.Be arranged with Charge level measurer 6 and following Charge level measurer 7 in the described transition feed bin 5 up and down in parallel, last Charge level measurer 6 links to each other with automatic control device 11 with following Charge level measurer 7, these transition feed bin 5 bottom devices have tapering transition hopper 9 and discharging control sluice 8, described storehouse in bulk 4 is arranged at tapering transition hopper 9 belows, described discharge duct 10 is arranged in the storehouse 4 in bulk, the upper end of this discharge duct 10 links to each other with tapering transition hopper 9 discharging openings, and the lower end is arranged in the storehouse 4 in bulk.Laterally offer several dumping pits 10.1 on the discharge duct 10.
Described discharge duct 10 constitutes by some joint discharge ducts are end to end, wherein the final section upper end is provided with flange 10.2, the lower end is uncovered, as Fig. 4~5, all the other respectively save discharge duct and all are provided with flange 10.2 in two ends up and down, as Fig. 2~3, can be according to different discharging height, the bolt together lengthening, the horizontal of discharge duct 10 opened a horizontal dumping pit every certain distance, distance between adjacent two dumping pits is as the criterion with this kind material does not produce segregation under free falling body state maximum height, and each saves discharge duct can be made into the full-length pipe.
Referring to Fig. 6, Fig. 6 is for adopting the high-order unloader of loose unpacked material of the present invention, dry mortar draws off from mixer discharge bucket 1, deliver to vertical bucket elevator 3 by horizontal screw conveyer 2, rise to transition feed bin 5, material is full, and last Charge level measurer 6 actions are sent and opened a sluice gate signal, automatically open by automatic control device 11 instruction discharging control sluice 8, dry mortar enters discharge duct 10 to storehouse in bulk 4 dischargings by tapering transition hopper 9, and material is near unsnatching following Charge level measurer 7 actions in the transition feed bin 5, send the barrier gate signal, automatic control device 11 sends instruction, and control apparatus time-delay barrier gate is unsnatched SELF CL discharging control sluice 8 substantially to transition feed bin 5 interior material.By the time material is full in the transition feed bin 5, and last Charge level measurer 6 sends opens a sluice gate signal, once circulation before the repetition.
Dry mortar directly is discharged into 4 bottoms, storehouse in bulk from tens meters high positions, along with the accumulation of dry mortar in storehouse in bulk is more and more higher, covered the bottom discharge openings of discharge duct 10, dry mortar just draws off from the horizontal dumping pit 10.1 of discharge duct 10 sides, piled when a minimum horizontal dumping pit, drawn off from next to the lowest horizontal dumping pit again.So until the highest horizontal dumping pit of discharge duct is piled, the material in storehouse in bulk just storage is full.
