Description

Linear vibrating screen underneath type dust pelletizing system and dust removal method
Technical field
The present invention relates to a kind of dustless discharge that can either be realized in dry-method sand manufacturing production line in sand reality screening process, again The linear vibrating screen underneath type dust pelletizing system and dust removal method of 50% or so electric energy can be reduced than background technology, belongs to dry-method sand manufacturing Production line dust pelletizing system manufacturing field.
Background technology
CN103433108A, title " a kind of dry-method sand manufacturing equipment and technique ", including jaw crusher, impact crusher, First classifying screen, dry-method sand manufacturing machine, the second classifying screen and concentration dust collecting system;Production process route is that the building stones in building stones storehouse lead to It crosses batcher and is equably sent into jaw crusher progress first time coarse crushing, broken material is transported in impact crusher Second of fine crushing is carried out, broken material is classified into the first classifying screen, and the sandstone less than 40mm passes through conveyer It is sent to dry-method sand manufacturing machine to carry out pulverizing sand processed, the rubble more than 40mm returns to impact crusher, into the sandstone of dry-method sand manufacturing machine Expect to be classified by being transported to the second classifying screen after the pulverizing of dry-method sand manufacturing machine, the sand less than 3mm is fed directly into finished sand In storehouse, the building stones more than 3mm back within dry-method sand manufacturing machine and are pulverized, and produce each airborne dust point and pass through concentrated dust collecting System concentrated dust collecting, the mountain flour after collection are transported to mountain flour storage and deposit.Its shortcoming:First, since the production line is open Structure causes each procedure to be required for setting dust pelletizing system, and high energy consumption, and pick-up performance is poor, in the sand that classifying screen separates Dust content is high;Second is that it can not realize dustless discharge.
The content of the invention
Purpose of design:The shortcoming in background technology is avoided, design is a kind of can either be real in dry-method sand manufacturing production line Dustless discharge in existing sand reality screening process, and the linear vibrating screen underneath type of 50% or so electric energy can be reduced than background technology Dust pelletizing system and dust removal method.
Designing scheme:In order to realize above-mentioned purpose of design.1st, the aspiration of negative pressure mouth is located at fixed linear vibrating screen discharge port The design that seal closure connects between multilayer movable type linear vibrating screen at the middle and upper levels portable linear vibrating screen is the skill of the present invention One of art feature.The purpose so designed is:By the design of dust suction chamber suction inlet below fixed linear vibrating screen and multilayer The top of upper movable type linear vibrating screen in portable linear vibrating screen, it dexterously make use of fixed linear vibration screen net It, by sand material sandstone and the characteristics of dust vibration dispersion, directly by the dust absorption in sand, is being avoided existing during sieving sand The method of the aspiration of negative pressure is recycled after the wind wind turbine air blast of people's profit dispels sand material in technology by the defects of dust siphons away in sand, directly Reduction energy consumption is connect, is economized on electricity per hour up to more than 50%, is not only significantly reduced energy consumption consumption, but also directly reduce negative pressure and remove Noise caused by dirt.2nd, the design of cyclone dust collectors and pulse bag type dust collector mixed binding is the technical characteristic of the present invention Two.The purpose so designed is:What cyclone dust removal strength siphoned away also has thinner sand in addition to dust, in cyclone dust removal Further recovery operation can be carried out further below, and cyclone dust removal is connected to pulse bag type dust collector, pulse bag type dust collector Control powder amount and airborne dust completely, the fine sand that the fine sand and vibration screen banks lowest level collected by cyclone dust collectors come out can be into Enter another modularization drawer type linear vibrating screen further fine sand and dust are separated, obtain the thinner grains of sand, Simultaneously because the dust being connected with pulse bag type dust collector suction inlet is provided in cyclone dust collectors tail end setting dust discharge upper part of channel The dust of dust discharge upper part of channel can all be sucked pulse bag type dust collector by absorbing path, the dust absorbing passage, the row of realization The purpose that dirt passage is discharged without dust, and enter the dust in pulse bag type dust collector after pulse bag type dust collector dedusting, Its clean gas is discharged by the discharge duct of pulse bag type dust collector.
Technical solution 1:A kind of linear vibrating screen underneath type dust pelletizing system, be equipped with below fixed linear vibrating screen one layer or The portable vibration straight line shaker of multilayer, seal closure cover on fixed linear vibrating screen discharge port surrounding and multilayer movable type straight-line oscillation On sieve, it is portable straight at the middle and upper levels with multilayer movable type linear vibrating screen that the aspiration of negative pressure mouth is located at fixed linear vibrating screen discharge port Seal closure connects between linearly coupled sieve.
Technical solution 2:A kind of dust collection method of linear vibrating screen underneath type dust pelletizing system, the negative pressure in cyclone dust collectors are inhaled Dirt mouth by fixed linear vibrating screen sieve lower section generate dust by the aspiration of negative pressure mouth suck cyclone dust collectors, and and whirlwind The micronic dust erect in dust discharge passage is sucked pulse by the dust discharge upper part of channel connection micronic dust the aspiration of negative pressure pipeline of erectting in deduster In sack cleaner after pulse bag type dust collector dedusting, clean gas is discharged by the discharge duct of pulse bag type dust collector.
The present invention is compared with background technology, first, the aspiration of negative pressure mouth in cyclone dust collectors is arranged on fixed straight-line oscillation Between sieving below sand export and above portable linear vibrating screen, it, can be by fixed linear vibrating screen vibrating screen without wind sand The mixed dust separated all siphons away, and avoids mixing for dust and sand, obtain it is relatively pure by sand;Second is that due to cyclone dust removal Device siphons away object as light dust, thus energy consumption is small, energy saving;Third, dust discharge passage of the pulse bag type dust collector in cyclone dust collectors Top sets suction inlet so that is absorbed into the micronic dust in dust discharge passage by pulse bag type dust collector, it is ensured that clean gas is by arteries and veins Rush the discharge duct discharge of sack cleaner.
