Description
Technical field
The invention belongs to material screening apparatus fields, buffer muscle more specifically to a kind of rotary screen and roller sieves
Machine.
Background technique
Cylinder round sifter is middle fine crushing material, commonly used equipment in gradation screening operation, by grain diameter size
It is sorted to control material, improves sharpness of separation, can be used for the every field such as chemical industry, fertilizer, environmental protection, feed, metallurgy, the scope of application
It is extremely wide.In the application of middle fine crushing material conveying, the application of rotary screen can be removed effectively wherein greater than mesh size
Foreign matter is realized to convey material as a raw material for production pure.The screening amount of rotary screen is to measure its working efficiency, is guaranteed normal
Therefore one important indicator of work in order to guarantee, or even improves working efficiency, it is necessary to improve the screening amount of rotary screen.
In general, the structures such as the screening amount of rotary screen and sieve pore, screen drum, the heeling condition and rolling of sieve nest and ground level
The factors such as the revolving speed of shaft screen are related.Therefore, traditional solution it is main there are two: adjust sieve mesh number size and
Adjust revolving speed and the inclination angle of rotary screen.Rotary screen sieve opening directly affects sieve effective area, and the sieve pore quantity on unit compass screen surface is got over
More, then sieve effective area is bigger, and material is bigger through the probability of sieve pore, therefore its output capacity and screening efficiency are got over
It is high；The sieve nest and ground level of cylinder round sifter are into heeling condition, then the design of reasonable inclination angle can effectively control object
Expect the flowing velocity on compass screen surface, helps to improve the screening efficiency of rotary screen.For example, Chinese invention patent, application number:
CN200910075488.3, the applying date: 2009.09.18 discloses a kind of mobile trommel sieve, including support frame, rotary screen,
It is fixedly connected on the transmission device of rotary screen one end, support frame top is equipped with support wheel, is mainly characterized by support frame lower part also
Equipped with movable pulley and the connection parts for being used for fixing support rack, rotary screen is coke powder char particle sieve, the middle piece of coke by different pore size
Charcoal sieve, middle bulk coke sieve, bulk coke sieve are formed by connecting, and it is 7~9 degree of inclination that rotary screen, which is placed with ground elevation,
The patent of invention is placed using the sieve of different dimensions and by adjusting rotary screen and ground elevation, improves coke
Screening quality and efficiency, it is ensured that normal continuous production.But straight reel sieve is during the work time, compass screen surface participates in work
Area is simultaneously unstable；Also, there is certain requirement to the water content of material, 10% need to be lower than.When the material sieved
When humidity is excessive, the viscosity of screening materials carrying just be will increase, and is easy to produce the material phenomenon sticky in compass screen surface, is influenced screening effect.
For example blast furnace granulated slag, blast furnace granulated slag are waste-height that when manUfaCtUre of pig iron is discharged from blast furnace hot melt state
Clinker is placed in water the product that rapid cooling obtains, therefore water content is higher than 25%.Blast furnace granulated slag main component be CaO,
SiO2、Al2O3, there is potential hydraulic gelling property, under clinker, lime, gypsum equal excitation agent effect, can be used as
Good cement raw material.And before realization is with blast furnace granulated slag as a raw material for production, it is necessary to be sieved to blast furnace granulated slag, to remove
Remove the material greater than mesh size, guarantee the size of raw material with it is pure.And due to the water content of blast furnace granulated slag height, humidity is big,
In screening process, be easier to occur the adhesion of storeroom, material and sieve it is sticky phenomena such as, sieve pore is blocked, to further drop
Low sieve participates in work area, leads to that screening amount is low, screening efficiency is low, it is difficult to meet the delivery requirements in production process, shadow
The progress worked normally is rung, therefore, in use process needs frequently to carry out artificial or mechanical chipping, to keep the smooth of sieve pore
It is logical, guarantee screening amount.Such as Chinese invention patent, application number: CN201410238556.4, the applying date: 2014.05.30 is announced
A kind of adjustable inclination angle self-cleaning vibration drum screen is mainly: being equipped with outer scraper plate on drum peripheral face and contains roller
And there is the upper and lower shield in a small amount of gap with outer scraper plate free end.Two dead turns at rotary screen both ends are located on two pairs of support rollers, rolling
Two supporting-roller shafts of cylinder side pass through shaft coupling and transmission shaft respectively and are connected with the same retarder and speed regulating motor, in above-mentioned rolling
Cylinder is equipped with inside strake mechanism.Rotary screen of the invention is able to carry out vibratory cleaning or vibration screening during the work time, and with
The real-time cleaning of inside and outside scraper plate cooperates, and can remain the clean conditions of rotary screen, effectively prevent sieve pore blockade, screening efficiency
It is high.But, however it remains energy consumption is high, the problem of high production cost.Also, in some yards for limiting rotary screen running parameter
It closes, screening amount appoints the delivery requirements being so extremely difficult in production process.
In conclusion for solving such as blast furnace granulated slag one kind, water content is big or tough material, in screening process
The material adhesion of middle generation, material and sieve it is sticky phenomena such as, caused, screening amount is low, and screening efficiency is low, it is difficult to full
The problems such as delivery requirements in sufficient production process, has the meaning of reality.
Summary of the invention
1. to solve the problems, such as
When sieving big water content or tough material, for easily occurring in screening process existing in the prior art
Material adhesion, material and sieve it is sticky, thus caused by sieve pore blockade, screen drum wire side work area is small, material screening amount is low,
High production cost and the high problem of energy consumption, the present invention provide a kind of rotary screen buffering muscle and cylinder round sifter, sieve in roller
In the case where machine work in every parameter constant, material adhesion is prevented as far as possible；It is sticky in compass screen surface to reduce material, to improve screening
Amount, increases the working efficiency of rotary screen；Further, it is possible to which engine loading is effectively reduced, achieve energy-saving and emission reduction purposes.
