Abstract
The utility model relates to the field of dryness during soil mortar production, in particular to a sand drying system. The sand drying system comprises a loading machine, a feeding device, a dryer and a dust collector, wherein a discharge port at the top end of the loading machine is located over a feeding hopper of the feeding device; the feeding device comprises the feeding hopper and a storage bunker located at the lower end of the hopper; the lower end of the storage bunker is communicated with a fluidized bed furnace of the dryer; the dryer comprises the fluidized bed furnace and a rotary furnace communicated with the fluidized bed furnace; an air inlet of the dust collector is connected with the upside of a discharge port of the rotary furnace; and a screening device is arranged below a discharge port of the dryer and comprises a primary vibrating screen classifier and a secondary vibrating screen classifier. According to the sand drying system, the sand screening device is arranged behind the dryer, the disadvantage that the preposed screening device easily causes blocking is avoided, the equipment failure rate is reduced, the production efficiency is improved, the screening device adopts two-stage screening, materials that are not screened thoroughly for the first time are subjected to secondary screening, sand can be screened more effectively, the screening efficiency is improved, the waste materials can be reduced by sufficient screening, and the utilization ratio is increased.
Description
Technical field
The utility model relates to the dry field in the cement mortar production process, is specifically related to a kind of sand drying system.
Background technology
In architectural engineering, cement mortar is generally by two kinds of effects, the one, basis and building wall are used as the adhesive of block building material, such as build rubble, common brick will be used cement mortar; The 2nd, plaster for indoor and outdoor, the bonding agent of insulation material etc.The raw material that cement mortar is general is exactly cement, sand and water, the size of sand particle, and humidity; quality to cement mortar; very important impact is arranged, and is all generally to adopt dry sand in industry, and granular size also can be controlled within the specific limits; prior art is in the process of dry sand; generally can just sieve sand before drying, but because the sand humidity in this time is very large, screening effect is bad; often meeting blocking screen subset, cause equipment fault.Seriously reduced production efficiency.
The utility model content
The utility model is for the larger sand blocking screen subset of humidity, and the problem that production efficiency is low proposes a kind of sand drying system.
the technical solution of the utility model is: a kind of sand drying system, comprise feeder, feed arrangement, drying device and dust arrester, feeder is a vertical feeder, the discharging opening on feeder top is positioned at the loading hopper of feed arrangement, feed arrangement comprises loading hopper and is positioned at the feed bin that holds of funnel lower end, holding the lower end of feed bin and the fluidized bed furnace of drying device is communicated with, drying device comprises fluidized bed furnace, the rotary furnace that is communicated with fluidized bed furnace, be connected with the air inlet of dust arrester above the discharging opening of rotary furnace, dust arrester comprises dirt pocket, the air exhauster that connects dirt pocket and discharging opening, upper end at dirt pocket is provided with the gas outlet, the bottom of dirt pocket also is provided with ash discharging hole, be provided with screening plant below the discharging opening of drying device, screening plant comprises one-level vibrating screen classifier and secondary vibration screening machine.
Described sand drying system, the furnace wall of described rotary furnace is divided into internal layer and skin, the hot air cavity that between internal layer and skin, formation and fluidized bed furnace are communicated with.
The beneficial effects of the utility model: after the utility model is arranged on drying device to the sand screening plant, avoided easily determining of obstruction of preposition screening plant, reduced equipment failure rate, improved production efficiency, screening plant adopts the secondary screening simultaneously, carries out regrading sieving for the first time halfway material, can more effective screening sand, improve the operating efficiency of screening, fully screening can reduce waste material simultaneously, has improved utilization rate.
