A kind of compound fertilizer drying
Technical field
The present invention relates to compound fertilizer processing technique field, more particularly, to a kind of compound fertilizer drying.
Background technology
Currently, during using drum granulating method production compound fertilizer, water vapour is often passed through to increase raw material
Humidity so that fertilizer can preferably bond balling-up.But, excessive moisture can influence product in compound fertilizer product
Quality, therefore, in order to moisture is general compound fertilizer is carried out using whizzer to acceptability limit in reducing product
Drying.Existing whizzer is simply made up of rotating cylinder, rotary electric machine and heater, and it is real that heater carries out heating to rotating cylinder
Now to the drying of fertilizer.Meanwhile, by rotary electric machine with drum rotation so that fertilizer makees centrifugal motion in rotating cylinder, due to
Fertiliser granulates are different from the quality of water, and the speed that the two does centrifugal motion is different, so can allow fertilizer and wherein by rotation
Moisture content separate, consequently facilitating the drying to fertilizer.
But, it is easily viscous because the compound fertilizer moisture having just enter into whizzer is higher in drying course
It is connected on the barrel of whizzer, by easily being stammered after heating so that the physicochemical property of fertilizer changes, so that seriously
Have impact on the production efficiency and quality of compound fertilizer product.
The content of the invention
The invention is intended to provide a kind of compound fertilizer drying, can solve the problem that fertilizer is easily stammered on drying machine, influence
The problem of compound fertilizer production efficiency and quality.
To achieve these goals, the present invention provides a kind of compound fertilizer drying, including vertically arranged rotating cylinder, rotating cylinder
The inner bag being connected is rotated including the shell being made up of insulation material and with shell, the upper end center of inner bag is fixedly connected with and turns
Axle, and inner bag top and bottom are respectively equipped with charging aperture and discharging opening, forms cavity between shell and inner bag, the upper end of cavity and
Lower end is respectively equipped with water inlet pipe and outlet pipe, and outlet pipe is provided with the first valve;The spiral shell of inner bag is also vertically provided around in cavity
Coil, inner bag is offseted and rotates with helix tube and is connected, and the two ends of helix tube are respectively positioned on the side wall of shell, the lower end position of helix tube
In the top of outlet pipe and it is provided with check valve;Vertically arranged transition chamber thereof, transition are also fixedly connected with the lateral wall of shell
Floater shot is provided with chamber, the two ends of helix tube and outlet pipe are connected with transition chamber thereof, and the lower end of transition chamber thereof is additionally provided with
Through hole, is provided with the second valve in through hole.
The know-why of the technical program and have the technical effect that:The technical program provides a kind of compound fertilizer drying, bag
Include vertically arranged rotating cylinder.High-temperature water passes through in the cavity that water inlet pipe enters between shell and inner bag, and is full of, so that right
Inner bag is heated so that the fertilizer in inner bag can be oven-dried.Shell is made of insulation material, can keep the temperature of water
Degree, the action time that extension once adds water.In addition, inner bag is rotated with shell be connected, can be relative by the effect of rotary electric machine
Shell rotates so that the fertilizer inside inner bag does centrifugal motion, so as to the moisture content in fertilizer be dried.
When needing to change the water in cavity, water enters transition chamber thereof by outlet pipe, and allows in transition chamber thereof
Floater shot is moved up in the presence of buoyancy, until floater shot enters in helix tube.Although floater shot density is small, its body
Product is larger so that floater shot still has larger quality, so during floater shot is moved down along helix tube rotation, can be continuous
The tube wall of helix tube is clashed into, allows helix tube to vibrate.Again because the rotation of helix tube and inner bag is connected, therefore, helix tube shakes
It is dynamic to pass to side wall of inner, allow side wall of inner to vibrate, the fertilizer that inner side of liner wall is bonded in so as to allow drops, it is to avoid fertilizer
Expect situation about being stammered on side wall of inner.Because the lower end of helix tube is additionally provided with check valve, the check valve be merely able to allow object from
Helix tube is unable to reverse movement to being moved in transition chamber thereof, it is possible to avoiding water from entering spiral during rising
Guan Zhong, the situation for causing floater shot to be moved down along helix tube.Afterwards, floater shot reaches the bottom of helix tube, can enter again
Enter in transition chamber thereof, prepare work next time.
Additionally, be additionally provided with through hole and the second valve in the lower end of transition chamber thereof, opening the second valve can just allow adapter cavity
Water outflow in room, completes the discharge of waste water, so as to the space of transition chamber thereof and cavity be spared, is easy to work next time
Make.
In sum, the technical program can allow wall of inner container to vibrate, so as to shake by setting floater shot and helix tube
Fall to being bonded in the fertilizer of inner bag inwall, it is to avoid the problem of fertilizer stammerer influence production efficiency.
Preferred scheme one:Based on base case, some projections are fixed with the inwall of the helix tube so that floater shot
Collided with projection during being moved down along helix tube, make the level of flapping of floater shot bigger, the shock with volute wall
Dynamics is bigger, so that the Oscillation Amplitude of side wall of inner is improved, the effect that enhancing fertilizer shakes off from inner bag inwall.
Preferred scheme two:Based on preferred scheme one, the through hole lower end is communicated with recovery tube.The heating of the recovery tube and water
Device is connected, and the water energy after heating again is enough again introduced into being operated in cavity, so as to realize the recycling to waste water, is saved
About water resource.
Preferred scheme three:Based on base case, the floater shot is ball.In general the density of rubber is less than water
Density, therefore, ball can float on the surface, and can be moved to the upper end of helix tube in the presence of buoyancy.In addition, rubber
Glueballs has certain elasticity, during movement in helix tube, by the collision with volute wall, can beat,
So as to strengthen the collision to tube wall, and then the vibration amplitude of inner bag is improved, the effect that enhancing fertilizer shakes off from inner bag inwall.
Preferred scheme four:Based on preferred scheme three, the support column for being rotated with it and being connected vertically is provided with the inner bag, supported
The lower end of post is fixedly connected through inner bag with shell, and several vertically arranged scraper plates, scraper plate position are fixedly connected with support column
In in inner bag and with inner side of liner wall sliding contact.Inner bag can relative support post rotate, inner bag rotate during, inner bag
Inwall is contacted with scraper plate, and the fertilizer being bonded on inwall can be wiped off by scraper plate.Additionally, side wall of inner is sent out in the presence of floater shot
Raw vibration, can increase the active force between side wall of inner and scraper plate, so that improves fertilizer scrapes effect.
Preferred scheme five:Based on preferred scheme four, the thickness of the side wall of inner is 1-3mm.When the thickness of side wall of inner
During less than 1mm, easily damaged because of the continuous shock of floater shot.And when side wall of inner thickness be more than 3mm when, side wall of inner because
The Oscillation Amplitude for floating ball impact and producing is too small, it is impossible to which the fertilizer that will be bonded on inwall shakes off.
