Abstract
The utility model relates to a kind of double-deck screening type coating machine cylinders, including coating machine drum body (1), coating machine drum body tail portion is equipped with upper screen (2) and lower screen (3), upper screen (2) is to extend the bulky grain sieve of installation in machine barrel inner ring, and lower screen (3) is the little particle sieve mounted in machine barrel outer ring extended portion.The utility model is particularly suitable for carrying out anti-caking coating and further screening to compound fertilizer granule in compound fertilizer production.
Description
Technical field
The utility model belongs to granulated fertilizer production and processing equipment, and in particular to a kind of machine barrel of coating machine, especially
Anti-caking coating and further screening are carried out to compound fertilizer granule suitable for compound fertilizer production.
Background technique
The compound fertilizer produced with rotary drum prilling process and high-tower granulation technique needs after fertiliser granulates molding through being subcooled
But, it sieves, and by one of anti-caking coating process, becomes compound fertilizer product.
Coating machine main working parts are the cylinder-shaped machine barrel of coating machine, and entire machine barrel is driven by base electrical machinery, around cylinder
Central axis revolution, the machine barrel of coating machine are mounted under normal circumstances with horizontal line in little inclination angle, and material is from coating machine
One end of cylinder is fed, and uniformly sprays one layer of liquid high temperature coating oil to the surface of material fed by coating machine atomizer,
Compound fertilizer granules are rolled to export direction along coating machine inner wall after part of the surface receives high temperature coating oil and are mixed, while receiving spiral shell
The coating powder that rotation measuring stick automatic gauge inserts.When compound fertilizer granules roll through entire coating machine barrel, coating oil, coating powder
It is just uniformly fixed on its surface, completes the coating process in composite heat transfer.
The control of compound fertilizer product small particles content and the control of large granular impurity content are an important fertilizer
The index of quality.Little particle can excessively fill the gap in fertiliser granulates, increase the connection effect between fertiliser granulates, so that compound fertilizer
Material is easy agglomeration in storing process, influences the quality of compound fertilizer.Bulky grain excessively will affect fertilizer user and use automation
Fertilizer application machine.
Compound fertilizer granules keep phase mutual friction to travel forward in production system, and compound fertilizer granules surface unavoidably has
A small amount of little particle and shed powder also have a small amount of coating pulvis because showing that attachment is not tight in fertiliser granulates in coating process
It is close and rubbed and fallen off, thus how to reduce after sieving process to the little particle generated before product packaging process and
Powder eventually enters into product packaging, is the production technique for fertilizer for needing to continuously improve.
In current compound fertilizer production technology, screening process is uniquely can will be big in large-particle fertilizer and production system
Granule foreign excludes the control process of finished product assembly line.But it is also possible to have a small amount of large-particle fertilizer and large granular impurity
Because being embedded in the position reason of bulky grain sieve, finished product assembly line is squeezed by other fertilizer.Therefore do not increasing life
Produce process increase under the premise of production system energy consumption together with screen out large-particle fertilizer and large granular impurity technique be can be effective
Improve compound fertilizer product quality.
Summary of the invention
The purpose of the utility model is to provide a kind of improved coating machine barrels, realize in coating machine to the mistake in compound fertilizer
Big or little particle excessively is further sieved.
Purpose of the utility model is realized as follows: a kind of bilayer screening type coating machine cylinder, including coating machine drum body,
It is characterized in that；Coating machine drum body tail portion is equipped with upper screen and lower screen, and upper screen is to extend to pacify in machine barrel inner ring
The bulky grain sieve of dress, lower screen are the little particle sieve mounted in machine barrel outer ring extended portion.Compound fertilizer granule first leads to
Oversized particles sieve screens out the bulky grain for not meeting granularity requirements, and then along lower layer, little particle sieve moves forward to compound fertilizer
Expect on finished product travelling belt, realizes further to particle screening excessive or too small in compound fertilizer.
Preferable scheme is: the spacing of the upper screen and lower screen is not less than 20cm.
Further scheme is: the aperture of the upper screen is 8mm*8mm, width 75cm；The lower screen
Aperture be 2mm*2mm, width 50cm.
The utility model completes coating process under the premise of additionally not increasing energy consumption, using the kinetic energy of coating machine itself,
Play the role of sieving size particles simultaneously, it can be ensured that the quality of complex fertilizer product.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is that the utility model installs upper screen three dimensional structure diagram.
Fig. 3 is that the utility model installs lower screen three dimensional structure diagram.
Specific embodiment
Muscle is done using 16mm band steel, 75cm wide, the bulky grain sieve that aperture is 8mm*8mm are rolled into annular as upper sieve
Net 2, and be fixed on the extended line of coating machine cylinder inboard wall tail portion with rivet, tail portion makes chute with 4mm steel plate；Due to coating machine
Cylinder 1 wall thickness about 4cm ~ 5cm, does muscle using 16mm band steel, and 50cm wide, the little particle sieve that aperture is 2mm*2mm are rolled into ring
Shape is fixed with rivet and is mounted on the extended portion line of coating machine cylinder body outer wall tail portion as lower screen 3, head and tail portion difference
Chute, two layers of sieve spacing at least 20cm are made with 4mm steel plate.Compound fertilizer granule first passes through bulky grain sieve and screens out not
Meet the bulky grain of granularity requirements, is then moved forward on compound fertilizer finished product travelling belt along lower layer's little particle sieve, this
Sample completes coating process under the premise of additionally not increasing energy consumption, using the kinetic energy of coating machine itself, plays while sieving size
The effect of particle.Bulky grain is separated in the process, and it is defeated that the chute through upper layer bulky grain sieve tail portion exports to feed belt
It sends back in production system crusher；Little particle is separated, and the chute through lower layer's little particle sieve lower head exports to lower section
Feed belt is transmitted back in production system crusher；Compound fertilizer finished product exports to finished product through the chute of little particle sieve tail portion and passes
Send Belt Conveying to product packaging process.
