Abstract

The utility model relates to a break-proof oscillating type bulk material dropping apparatus, which is mainly composed of a material box and an oscillating plate, wherein, both ends of the material box which is arranged below the dropping bulk material are provided with a bulk material inlet and a bulk material outlet, and the closing oscillating plate is arranged between the bulk material inlet and the bulk material outlet in the material box; the shapes of the section of the material box and the oscillating plate can be designed into different geometric shapes; the opening and the closing of the oscillating plate can be controlled by gravity, liquid, gas, electricity, magnetism, elastic force, machinery, manpower or the combination thereof. When the bulk material goes through the utility model, the bulk material is blocked by the oscillating plate, and the speed of the bulk material is reduced to zero; then the bulk material begins to drop freely from idle state. The complete set of the break-proof apparatus can be composed of one or more than one apparatus based on the utility model or auxiliary diversion flow channels of the utility model, the distribution range between the two upper and lower neighbouring apparatus based on the utility model is determined according to the property of the bulk material, and the auxiliary diversion flow channels can be additionally arranged among the apparatus based on the utility model. When the dropping bulk material goes through one or more the apparatus based on the utility model, the long full-range drop to the bottom in one time in the prior art can be changed into short-range section divided drops. Thereby, the breaking of the bulk material caused by fast dropping speed and high impact force can be avoided or reduced with the aid of the utility model.

Description

Bulk cargo oscillating type buffering anti-broken gear

[technical field] the utility model relates to a kind of bulk cargo oscillating type buffering anti-broken gear, and especially a kind of being applicable to by the deadweight whereabouts carried frangible bulk cargo continuously, prevents and reduce the device of bulk cargo fragmentation.

[background technology] in uninterruptedly carrying as frangible bulk cargo processes such as grain, coal, cokes by deadweight landing, bulk cargo usually can be because of the drop that lands be big, when its with accept object (ground or facility) speed height when contacting, impulsive force is greatly and fragmentation.Carry in the free-falling process in storage as dried corn, percentage of damage is up to 30%, and stream takes huge.

[summary of the invention] the purpose of this utility model is to provide a kind of bulk cargo oscillating type buffering anti-broken gear, is used for alleviating bulk cargo at continuous free-falling process degree of crushing.

The purpose of this utility model realizes by following technological means.

A kind of bulk cargo oscillating type buffering anti-broken gear is characterized in that said device comprises: be positioned at bulk cargo below, whereabouts, be used to accept the hopper of bulk cargo, the hopper two ends are provided with the bulk cargo import and export, between the import and export sealing oscillating deck are housed in the hopper.Equipment package is made up of one or more devices and auxiliary water conservancy diversion chute simple in structure.Hopper each by bulk cargo wash away that the equal liner in position is pollution-free, buffering, abrasion resistant flexible material, in the hope of fragmentation that alleviates bulk cargo and the service life that prolongs equipment.The hopper two ends are provided with the bulk cargo import and export.Be provided with the oscillating deck that rotates with rotating shaft between the import and export in the hopper, in order to the open and close hopper.When bulk cargo falls continuously, through one or more devices and auxiliary water conservancy diversion chute, can make once and directly fall at the end, the landing that drop is big becomes the little segmentation landing of drop.When bulk cargo passes through each this device, all be subjected to stopping of oscillating deck, before it, form the certain thickness obstruct bed of material, can make the back fall into hopper and have bulk cargo moment of convenient speed staticly to get off, the static bulk cargo that gets off is cumulative, when reaching certain thickness, wash oscillating deck open, descend with zero-speed.Oscillating deck opening degree size depends primarily on the size of whereabouts bulk cargo flow.Be that flow is big, opening degree is big; Flow is little, and opening degree is little.This apparatus features is: before the oscillating deck, remain one deck and intercept the bed of material, the static zero-speed then of the material that falls is above descended.Like this, can control the distance between two devices, just can avoid or alleviate the fragmentation of bulk cargo by finding out the speed of fall that material allows.Distribution distance between adjacent upper and lower two devices is decided on the character of bulk cargo.The geometric configuration of above-mentioned hopper section and sealing oscillating deck can be that garden, side, square, ellipse, polygon etc. are multiple.Being provided with of oscillating deck can be one or more groups in each hopper.It can be gravity, gas, liquid, electricity, magnetic, machinery, manpower or its multiple combination that oscillating deck is opened; The oscillating deck closure also can be gravity, gas, liquid, electricity, magnetic, machinery, manpower or elastic force.Hopper and auxiliary water conservancy diversion chute thereof are lined with pollution-free, the antistatic liner of one deck as the surface of hopper inside face and oscillating deck, deflecting plate, bearing plate, are used for antistatic and sparkproof produces, and avoid bulk cargo dust explosion, accident such as on fire to take place.Its measure is: all places that the metal direct contact is arranged or washed away by material, all do liner at interval or with antistatic ultra-high molecular weight polyethylene with pollution-free rubber.According to different particular cases, also can set up the simply auxiliary guiding device of other form structure between two devices.The equipment package end-of-job, this installs in another device of reliable its underpart special-purpose the rise and backs down mechanism's (or artificial etc.) and open oscillating deck, makes the residue bulk cargo free-falling in the hopper, and does not accumulate.

This bulk cargo oscillating type buffering anti-broken gear can existing one be fallen the end, and long distance is omnidistance free-falling bulk cargo continuously, and by hypotelorism, favorably situated a plurality of are installed and auxiliary water conservancy diversion chute, the bulk cargo falling speed can be reduced to permissible value.This will greatly reducing the bulk cargo speed of fall, thereby avoid big fast apart from speed of fall apart from becoming small distance segmentation landing modes greatly, impulsive force causes a large amount of fragmentations of bulk cargo greatly.Measures such as that this device and a complete set of equipment all have is antistatic, produce no spark, soft wear-resisting, anti-pollution can be exempted bulk cargo and therefore cause dust explosion, accident such as on fire, and have environmental protection, advantages such as long service life.When a complete set of equipment work finishes, the oscillating deck of this device is opened by the special-purpose jacking mechanism that is positioned at its another device of below, allows clout free-falling in the hopper, and not remaining.Each this device can suspend in midair or monomer is fixed.
