Embodiment
Be described in detail below in conjunction with the preferred embodiment of accompanying drawing to biomass grain forming system of the present invention.
Biomass grain forming system shown in Fig. 1 is made up of biomass powder crushing device 1, particle drying installation 2, material particles shaped device 3 and thermal-pump unit 4.
Biomass powder crushing device rolls biological material and pulverizes.As shown in Figure 2, from biomass direction of motion, biomass powder crushing device comprises feeder 11, paired milling roller 12, pulverization roller 13 and discharging blower fan 14 successively.Feeder 11 for cross section be U-shaped pipeline, biological material enters into biomass powder crushing device 1 from feeder and pulverizes.Milling roller 12 is symmetrical arranged in pairs up and down, in order to roll biomass.And as shown in Figure 3, milling roller 12 is the rubber rollers with fin, in roller compaction process, the fin of up-down rollers staggers mutually, and the spacing up and down between milling roller 12 can adjust according to different biological materials, to ensure the effect rolled.Biological material after rolling cuts via pulverization roller 13, this pulverization roller 13 is provided with multiple blade 131(that the circumferential surface along roller arranges with helical array and sees Fig. 4), pulverization roller 13 rotates at work, and the blade on pulverization roller 13 realizes cutting to rolling artifact material.In order to the pollution preventing the biological material of moisture content from causing roller, pulverization roller 13 is stainless steel rider, multiple blade 131 is arranged on roller 13 by suitable way with helical array, these modes can be fixed for welding, bolt or rivet, if consider the replaceability of blade, preferably adopt bolt counteredge.Blade on pulverization roller 13 is corresponding with the discharge port of upper and lower milling roller 12, and along with the rotation of pulverization roller 13, blade 131 is cut into segment the biological material after rolling; The blade of spiral is arranged sideling, cuts off the stalk after rolling successively, become particle in blade rotation process.
The particle fallen is sent to particle drying installation 2 by discharging blower fan 14, makes moisture controlled in particle within proper range.
In general granulating system, do not possess water ratio conditioning equipment, thus, in granulation process, usually because the water ratio situation in biological material is different, often a collection of produced particle, its effect is also different.When granulation, if the water ratio in biological material is too high, then can discharges large quantity of moisture when granulation, affect granulation outcome, even can adhere on granulating equipment, cause jam or the inefficacy of equipment, greatly have impact on working efficiency and particle effect.For this reason, the present invention is provided with particle drying plant, and carry out drying to the particle after pulverizing, thus ensure before carrying out granulation extruding, particle reaches suitable water ratio scope, is convenient to the carrying out of granulation.
As shown in Figure 5, particle drying installation 2 forms primarily of travelling belt 21, housing 22, controllable electric heating unit 23, water ratio detector 24, humidity sensor 25, temperature sensor 26 and drying control system (not shown).Particle is blown on the travelling belt 21 of particle drying installation by discharging blower fan 14, housing 22 comprise be connected with discharging blower fan 14 blow entrance 221, and by dried particle discharge discharge port 222.Water ratio detector 24 is arranged on and blows near entrance 221 and discharge port 222, to detect the water ratio in particle.Humidity sensor 25, temperature sensor 26 and controllable electric heating unit 23 are arranged on housing 22.The transmission system (not shown) of drying control system and travelling belt 21, controllable electric heating unit 23, water ratio detector 24, humidity sensor 25, temperature sensor 26 form correspondence.The water ratio signal that water ratio detector 24 detects is sent to drying control system, drying control system adjusts the drying temperature of controllable electric heating unit 23 accordingly, real time temperature in housing 22 and moisture signal are sent to drying control system by humidity sensor 25, temperature sensor 26, thus adjust controllable heater 23 the need of improving temperature further according to real time temperature and humidity.Travelling belt 21 geneva motion, drying control system is according to the drying regime (the water ratio signal that the water ratio detector 24 near discharge port 222 feeds back) of particle, signal is sent to the transmission system of travelling belt 21, if water ratio is too high in particle, still need further drying, then drying control system sends the signal that stop motion answered by travelling belt 21 to transmission system; After detecting in particle that water ratio reaches requirement, drying control system is according to the drying regime (the water ratio signal that the water ratio detector 24 near discharge port 222 feeds back) of particle, signal is sent to the transmission system of travelling belt 21, start travelling belt 21 to move on, particle after drying is discharged from discharge port 222, enters into material particles shaped device 3 and carry out granulation.
Wherein, described drying control system, when the discharging blower fan 14 of particle via shredding unit 1 continues to be blown on travelling belt, meanwhile travelling belt operates forward, until a certain amount of particle piled up by the travelling belt being positioned at housing 22, just shuts down.At this moment, be arranged in the water ratio that the water ratio detector 24 blowed near entrance 221 starts to detect biomass, then water ratio detected result is sent to drying control system.After drying control system acceptance to water ratio detected result, start controllable electric heating unit 23 and heat.It should be noted that, in order to ensure speed and the heats of heating, the temperature that controllable electric heating unit 23 discharges is between 30 DEG C to 90 DEG C, because drying temperature is too high, humidity is lower, dry particle can be made to become fragile in thermal histories, be unfavorable for the intensity ensureing shaped granule, easily loose; If the temperature of drying is too low, humidity is too high, then slowly dried.In order to control suitable temperature, inner walls 22 is provided with humidity sensor 25, temperature sensor 26, drying control system according to the real-time detected result of humidity sensor 25 and temperature sensor 26, the Heating temperature of adjustment controllable electric heating unit 23.Every 1 minute, be positioned at blow entrance 221 and discharge port 222 two water ratio detectors 24 all by measured water ratio data feedback to drying control service system, when detected water ratio is between 15%-20%, drying control system sends the signal stopping heating to controllable electric heating unit 23, drying control system sends the signal of running to the transmission system of travelling belt 21 simultaneously, thus dried particle can be dropped among the broach hopper 31 of material particles shaped device 3 from discharge port 222.
