Description
Technical field
Machine-made sand production technical field is the utility model is related to, specially a kind of Machine-made Sand dry method bugduster apparatus.
Background technology
In Process of Engineering Construction, important component of the sandstone as concrete structure material, its quality good or not is to whole
The quality and durability of individual engineering have very important influence., can from economy on the premise of satisfaction is with sand performance indications
Capable scheme, construction quality requirement should be met, efficiently control production cost, the so ground in natural sand resource shortage again
Area, being not only using reaction type efficient fine crusher or the high-quality Machine-made Sand progress concrete construction production of impact crusher manufacture can
Capable, its comprehensive benefit is also significant.Machine-made Sand production line have oscillating feeder, jaw crusher, sand making machine, vibratory sieve and
The equipment such as adhesive-tape machine combine.
The particle stone flour that the size that 10%~20% can be mingled with the production process of Machine-made Sand is 75 μm, appropriate stone flour
The defects of machine-made sand concrete service behaviour difference can be improved, increase concrete anti-compression, rupture strength, but the too high meeting of content of stone powder
The performance of influencing mechanism sand concrete, so gumming must be carried out to Machine-made Sand.
Traditional gumming mode, is covered on Machine-made Sand vibratory sieve using negative pressure dust removing device, is by screening by vacuum cavitations
It is less than 0.075mm particle in system top absorption mechanism sand, but a disadvantage is that：First, it is less than by vacuum magnitude control removing
0.075mm particle, vacuum cavitations are big, easily cause 0.15mm, 0.3mm, 0.6mm particle and are sucked out；Vacuum cavitations are small, up to not
To the purpose for removing the particle less than 0.075mm, the mechanism sand particle size distribution of causing is difficult to control；Secondly as Machine-made Sand mother metal
Nature difference is larger, also different less than 0.075mm granule content size after crushing, and causes negative pressure adjustment difficult；Furthermore rely on
Top depression dust-removing absorption extends sieving time, it is necessary to try one's best, and can be only achieved effect, production efficiency is low.
In order to improve machine-made sand production capacity, and it can guarantee that the gumming effect of Machine-made Sand so that Machine-made Sand granular-grade
With moderately good control can be obtained, it is very necessary to study a kind of simple and direct applicable Machine-made Sand dry-method dust-removal device.
The content of the invention
The utility model is unable to reach good gumming in order to solve during Machine-made Sand, using the bugduster apparatus of routine
A kind of the problem of effect causes mechanism sand particle size distribution to be well controlled, there is provided Machine-made Sand dry method bugduster apparatus.
The utility model is achieved by the following technical solution：A kind of Machine-made Sand dry method bugduster apparatus, including casing and
The rotary screen being arranged in casing, casing top are provided with motor and negative pressure dust removing device, and casing bottom is provided with the warm air-supply of wind
Device, is provided with expanded metal lath between casing and rotary screen, expanded metal lath is fixedly connected into cylindrical structural and with casing, opened on expanded metal lath
There are multiple filter openings, a diameter of 0.075mm of filter opening；The link position of rotary screen bottom and casing both ends offers charging aperture respectively
And discharging opening, rotary screen are inclined to set along charging aperture to the direction of discharging opening.
The inclination angle of rotary screen is 5 ° ~ 10 °.Rotary screen, which is inclined to set, is advantageous to sand while screening is rotated to discharging
Mouth transports, and inclination angle setting is too small, can cause the bulk deposition of sand material in rotary screen so that Machine-made Sand efficiency is extremely low；Incline
Oblique angle setting is excessive, and sand material in rotary screen can be caused to have little time to sieve, and is just flowed out from discharging opening, does not have good gumming effect
Fruit.
Motor is connected by circuit with rotary screen.Motor provides power for rotary screen, it is effectively operated.
The temperature that wind warms up air-supply arrangement normal work generation hot blast is 60 DEG C ~ 80 DEG C.Micro-moisture may be carried in sand material,
The effect that wind warms up air-supply arrangement is to be dried the moisture carried in sand material, is easy to powder of the diameter less than 0.075mm in sand material
Dirt separates；Meanwhile under the drive of hot blast, dust of the diameter less than 0.075mm can float on the top of rotary screen, be easy to negative pressure
Dust arrester is absorbed to it.
The course of work：First, open wind and warm up air-supply arrangement and negative pressure dust removing device, then send Machine-made Sand material from charging aperture
Enter in rotary screen, rotary screen is operated under the drive of motor, and sand material moves therewith in rotary screen, and wind warms up air-supply arrangement and blown
The sand material of motion is dried and the dust of lighter weight is floated on the top of rotary screen by the hot blast gone out；Due to rotary screen and
Expanded metal lath is provided between casing, multiple a diameter of 0.075mm filter opening is uniformly laid with expanded metal lath so that only diameter is little
It can pass through expanded metal lath in 0.075mm dust；Further, in the presence of negative pressure dust removing device, diameter is not more than
0.075mm dust carries out absorptive collection；Finally, sand of the diameter more than 0.075mm can enter conveyer belt by discharging opening, and then
It is collected standby, completes whole Machine-made Sand dry method gumming process.
The utility model compared with prior art, has advantages below：
Traditional vibratory sieve is improved to rotary screen so that gathering materials has effective sifting area bigger, contributes to increase to produce
Ability, and the expanded metal lath for carrying a diameter of 0.075mm filter openings is set up between rotary screen and casing so that no matter negative pressure more mostly not
More than 0.075mm particle loss, pledge system sand particle size distribution can be caused；Air-supply arrangement is warmed up to coordinate negative pressure to remove by increasing wind
Dirt device, and its mutual alignment is that wind warms up air-supply arrangement under, negative pressure dust removing device is upper so that rotary screen is in the course of work
In, by wind warm up air-supply arrangement discharge hot blast drives dust to raise up principle, be easy to negative pressure dust removing device to a diameter of 0.075mm
Following dust absorption, and wind warms up supply air system and can be suitably used for the different material of various water content, equipment is light, price material benefit,
Cost performance is high；It can be good at removing a diameter of 0.075mm by Machine-made Sand dry method bugduster apparatus described in the utility model
Following granule content, retain more than 0.075mm particles, the grain composition of pledge system sand is stable, so as to improve machine-made sand
Quality.
