Description
(1) technical field
The present invention relates to a kind of high discharge system 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 system for loose unpacked material of segregation effectively.
The object of the present invention is achieved like this: a kind of high discharge system for loose unpacked material, described unloader comprises the mixer discharge bucket, horizontal screw conveyer, vertical bucket elevator, the transition feed bin, the tapering transition hopper, storehouse in bulk and discharge duct, described mixer discharge bucket is arranged at the horizontal screw conveyer top, the discharging opening of mixer discharge bucket links to each other with the inlet point of horizontal screw conveyer, described vertical bucket elevator places the horizontal screw conveyer rear side, the inlet point of the bottom of vertical bucket elevator links to each other with the discharging opening of horizontal screw conveyer, described transition feed bin is arranged at the rear side of vertical bucket elevator upper part discharge port, this 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 system 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 system 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.
High discharge system for loose unpacked material of the present invention, be provided with a pipe cleaning device between described storehouse in bulk and the discharge duct, described pipe cleaning device comprises waling stripe, sealed bearing, vibration proof mounting and vibrator, vibration proof mounting is installed in storehouse in bulk outer wall, vibrator is installed on the vibration proof mounting, sealed bearing is installed in the bulkhead place in storehouse in bulk, and an end of waling stripe is connected with the middle part of discharge duct, and the sealed bearing that the other end of waling stripe passes the bulkhead place in storehouse in bulk is connected with vibration proof mounting.
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.
Dry mortar is long as the storage time in storehouse in bulk, because gravity to the compression of bulk material in the storehouse, makes it each other in conjunction with tightr, causes that easily taking arch stops Flow of Goods and Materials, needs this moment broken arch to handle, and that destroys material takes the arcuation attitude.Bottom discharge duct, also cause easily and take arch, just need to start pipe cleaning device this moment, vibrator produces disturbance force and is delivered on the discharge duct by waling stripe, discharge duct is clashed into and vibrate, destroy the arch of taking of the interior material of pipe, make the interior material of pipe from progressively shaking off, reach the pigging effect to free-flowing.
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.
