Description

Dry method sand production line special combination dust pelletizing system

Technical field

The utility model relates to a kind of dustless discharge that can either realize in dry method sand production line in the real screening process of sand, dry method sand production line special combination dust pelletizing system and the dust collection method of about 50% electric energy can be reduced again than background technology, belong to dry method sand production line dust pelletizing system and manufacture field.

Background technology

CN103433108A, title " a kind of dry method sand equipment and technics ", comprise jaw crusher, impact crusher, the first classifying screen, dry method sand machine, the second classifying screen and concentrated dust collecting system, production process route is, the building stones in building stones storehouse are sent into jaw crusher equably by batcher and are carried out first time coarse crushing, material after fragmentation is transported in impact crusher and carries out second time fine crushing, material after fragmentation enters the first classifying screen and carries out classification, the sandstone being less than 40mm is delivered to dry method sand machine by conveyer and is carried out pulverizing sand processed, the rubble being greater than 40mm returns impact crusher, the sand material entering dry method sand machine is transported to the second classifying screen and carries out classification after the pulverizing of dry method sand machine, the sand being less than 3mm is directly admitted in finished product sand storage, the building stones being greater than 3mm return to dry method sand machine and pulverize, produce each airborne dust point by concentrated dust collecting system concentrated dust collecting, stone flour after collection is transported to stone flour storage and deposits.Its weak point: one is because this production line is Open architecture, and cause each procedure all to need to arrange dust pelletizing system, and energy consumption is high, pick-up performance is poor, and in the sand that classifying screen separates, dust content is high; Two is to realize dustless discharge.

Utility model content

Purpose of design: avoid the weak point in background technology, design a kind of dustless discharge that can either realize in dry method sand production line in the real screening process of sand, the dry method sand production line special combination dust pelletizing system of about 50% electric energy can be reduced again than background technology.

Design: in order to realize above-mentioned purpose of design.1, the design of cyclone dust collectors and pulse bag type dust collector mixed binding is one of technical characteristic of the present utility model.The object of such design is: what cyclone dust removal brute force siphoned away also has thinner sand except dust, further recovery operation can also be carried out below cyclone dust removal, cyclone dust removal is connected to pulse bag type dust collector, pulse bag type dust collector controls powder amount and airborne dust completely, the fine sand collected through cyclone dust collectors and vibrate screen banks orlop fine sand out and can enter another one modularization drawer type linear vibrating screen and come further fine sand to be separated with dust, obtain the thinner grains of sand, have owing to erectting dust discharge channel upper at cyclone dust collectors tail end the dust absorbing passage be connected with pulse bag type dust collector suction port simultaneously, the dust of dust discharge channel upper all can be sucked pulse bag type dust collector by this dust absorbing passage, realize the object that dust discharge passage is discharged without dust, and the dust entered in pulse bag type dust collector is after pulse bag type dust collector dedusting, its clean air is discharged by the discharge duct of pulse bag type dust collector.2, main dust suction chamber dust sucting pipeline suction port to be positioned at below fixed linear vibrating screen and above upper portable linear vibrating screen between design, be technical characteristic two of the present utility model.The object of such design is: above portable linear vibrating screen on the design of dust suction chamber suction port is below fixed linear vibrating screen and in the portable linear vibrating screen of multilayer, it make use of fixed linear vibration screen net in the process of sieve sand dexterously by the feature of sand material sandstone and dust vibration dispersion, directly by the dust absorption in sand, avoid the defect that dust in sand siphons away by method that sand material dispels rear recycling the aspiration of negative pressure by the air blast of the profit of people in prior art wind blower fan, direct reduction energy consumption, economize on electricity per hour reaches more than 50%, not only significantly reduce energy consumption consumption, and directly reduce the noise that depression dust-removing produces.

Technical scheme: a kind of dry method sand production line special combination dust pelletizing system, is made up of cyclone dust collectors, pulse bag type dust collector, precipitator dust dust suction chamber, main dust suction chamber, discharging dust suction chamber; In cyclone dust collectors, dust discharge channel upper is communicated with micronic dust the aspiration of negative pressure pipeline suction inlet by bend pipe, the aspiration of negative pressure tube outlet is communicated with the pulse bag type dust collector the aspiration of negative pressure mouth being positioned at dust discharge beneath galleries, precipitator dust dust suction chamber covers on the cone ash bucket of cyclone dust collectors, main dust suction chamber covers on modular vibration screening and is set up, on the guide passage that discharging dust suction chamber covers on modular vibration screening device and precipitator dust dust suction chamber be communicated with by the dust sucting pipeline of dust sucting pipeline with main dust suction chamber with the blast suction port of discharging dust suction chamber.

The utility model is compared with background technology, one be the aspiration of negative pressure mouth in cyclone dust collectors to be arranged on below fixed linear vibrating screen sand export and above portable linear vibrating screen between, it is without the need to wind sand, the mixed dust that fixing linear vibrating screen vibratory sieve separates all can be siphoned away, avoid mixing of dust and sand, obtain relatively pure by sand; Two is that thus energy consumption is little, energy-conservation because cyclone dust collectors siphon away the dust that thing is light weight; Three is that pulse bag type dust collector arranges suction port at the dust discharge channel upper of cyclone dust collectors, the micronic dust entered in dust discharge passage is absorbed by pulse bag type dust collector, guarantees that clean air is discharged by the discharge duct of pulse bag type dust collector.
