The cooling speed that the fertilizer drop 400 is 2.1-3.2 DEG C/sec with cooling velocity is controlled in 221 transmit process of conveyer belt
Degree cooling.
In a further embodiment, the distributing device 210 includes discharge port 211, the direction that the discharge port 211 discharges
It is vertical with the conveyer belt 221.That is fertilizer drop 400 comes out the rear side along perpendicular to conveyer belt 211 from discharge port 211
To the receiving end 2211 for falling in conveyer belt 211.
It in a further embodiment, further include temperature-controlling component 224 in the cooling component 222, the temperature-controlling component 224
For monitoring the temperature on 221 surface of conveyer belt.
In a further embodiment, the temperature-controlling component 224 includes first temperature probe 225 and second temperature probe
226, wherein the first temperature probe 225 is for monitoring conveyer belt 221 in the temperature on 2211 surface of receiving end, second temperature
Degree probe 226 is for monitoring conveyer belt 221 in the temperature on 2212 surface of discharge end.Fertilizer drop 400 is fallen on conveyer belt 221
Afterwards, the temperature highest at receiving end 2211, the temperature at discharge end 2212 is minimum, thus by monitoring maximum temperature at and
Temperature at minimum temperature knows that 221 surface of conveyer belt controls use in the temperature range of cooling fertilizer drop 400, and with this
Temperature in 221 surface of conveyer belt of cooling fertilizer drop 400.It is understood that temperature-controlling component 224 can also include monitoring
The temp probe of surface temperature between the receiving end 2211 and discharge end 2212 of conveyer belt 221 at any position.
In a further embodiment, the cooling component 222 is also used to control the conveyer belt 221 and the fertilizer solution
The surface temperature of 400 contact of drop is 10-40 DEG C.Such as when first temperature probe 225 monitors conveyer belt 221 at receiving end 2211
When the temperature on surface is more than 40 DEG C, cooling component 222 reduces the cooling temperature of conveyer belt 221, is being connect with reducing conveyer belt 221
The temperature on surface at receiving end 2211 can avoid causing fertiliser granulates 10 are cooling not enough to influence product quality due to temperature is excessively high.
Again for example when the temperature that first temperature probe 225 monitors the surface at receiving end 2211 of conveyer belt 221 is lower than 10 DEG C, cooling group
Part 222 increases the cooling temperature of conveyer belt 221, to increase the temperature on the surface at receiving end 2211 of conveyer belt 221, can avoid
Because fertilizer drop 400 falls in lower 221 surface of conveyer belt of temperature, and quickly quenching occurs, so that fertiliser granulates 10 and transmission
One end with 221 contacts forms the high compact part of consistency, so that the water solubility for the fertiliser granulates 10 that rapid cooling is formed is not
It is good.
In a further embodiment, the cooling component 222 includes cooling medium 223, and the cooling medium 223 is used for
Heat exchange is carried out to the conveyer belt 221.It specifically includes and conveyer belt 221 is cooled down or heated up.Wherein cooling medium 223 is wrapped
Include but be not limited to one of water, cooling oil.
In a further embodiment, the cooling component 222 further includes controller 227, and the controller 227 receives institute
The temperature information of the monitoring of temperature-controlling component 224 is stated, and controls the temperature on 221 surface of conveyer belt according to the temperature information.
In a further embodiment, the controller 227 is also used to control cooling medium in the cooling component 222
Temperature in 223.When controller 227, which receives the temperature information that the temperature-controlling component 224 monitors, is more than 40 DEG C, the controller
Temperature in the 227 control cooling components 222 in cooling medium 223 reduces, to reduce the temperature on 221 surface of conveyer belt.When
When controller 227 receives the temperature information of the monitoring of temperature-controlling component 224 lower than 10 DEG C, the controller 227 controls described cold
But the temperature in component 222 in cooling medium 223 increases, to increase the temperature on 221 surface of conveyer belt.
The embodiments described above only express several embodiments of the present invention, and the description thereof is more specific and detailed, but simultaneously
Limitations on the scope of the patent of the present invention therefore cannot be interpreted as.It should be pointed out that for those of ordinary skill in the art
For, without departing from the inventive concept of the premise, various modifications and improvements can be made, these belong to guarantor of the invention
Protect range.Therefore, the scope of protection of the patent of the invention shall be subject to the appended claims.
