Compared with prior art, the utility model has the following beneficial effects:
1. the utility model feed inlet to store up for connecting with the discharge port of fluid bed granulator under the action of vacuum pump Low pressure is presented inside feed bin and enters storage bin convenient for material, level-sensing device is high for constantly detecting the material accumulated in slow storage bin It spends, is transmitted to controller after the signal processing that level-sensing device will test, controller can control solenoid valve I, solenoid valve II and electricity Magnet valve III it is on and off;When carrying out blanking, solenoid valve I, solenoid valve II and solenoid valve III are placed in original state: Solenoid valve I is in the open state, and solenoid valve II and solenoid valve III are in close state, and material is first into storage bin, then Slow feed bin is entered by solenoid valve I, is accumulated in slow feed bin, level-sensing device carries out the height for constantly detecting material position, works as object When material accumulation height reaches default maximum height value, level-sensing device passes the signal along to controller, and controller controls electricity first Magnet valve I is closed, and then controls solenoid valve II and solenoid valve III is opened, and the outlet of solenoid valve II is for entering the wind, so that slow feed bin air pressure It is consistent with atmospheric pressure, facilitate the discharge of material;After the material discharge of accumulation, after the signal processing that level-sensing device will test again It is transmitted to controller, controller controls solenoid valve II first and solenoid valve III is closed, and it then controls solenoid valve I and opens, storage bin The material of interior accumulation will go into slow feed bin, so repeat;When carrying out blanking, does not need to close vacuum pump, accumulate Material afterwards is discharged after entering slow feed bin through discharge gate, and storage bin is accumulating always material, it is in running order in, in turn Blanking efficiency is improved, economic benefit is increased;Frequent progress closing vacuum pump is not needed when blanking simultaneously, is extended The service life of vacuum pump reduces the loss of the electric energy in closing vacuum pump.
2. solenoid valve II described in the utility model is connected with blower, blower is connect with controller, carries out discharge in slow feed bin When, i.e., solenoid valve I is closed, and when solenoid valve II and solenoid valve III are opened, controller controls blower starting, to slow feed bin Interior air blast increases the pressure in slow feed bin, accelerates the velocity of discharge of material, meanwhile, under the blowing of blower, for attachment It can be also discharged in the material of slow feed bin inner wall, avoid material waste.
3. III exit of solenoid valve described in the utility model is equipped with blanking separator tube, blanking separator tube is made of cloth;Blanking The setting of separator tube is so that play the role of buffering to the material inside slow feed bin when discharge, while can be avoided dust It leaks, pollutes air;Further, when slow feed bin carries out discharge, blanking separator tube can also play guidance to material and make With directly material can be sent in next process and be further processed.
4. being connected with first pipe at vacuum pump outlet described in the utility model, first pipe can connect with fluid bed granulator The air inlet of the plate heat exchanger connect connects;Vacuum pump at work, can make storage bin become low-pressure state, convenient for boiling It rises the material in granulator and enters storage bin, vacuum pump will go into direct emission after the hot-air in storage bin is extracted out together, The waste of heat is caused, the air inlet connection for the plate heat exchanger that first pipe can be connect with fluid bed granulator is logical in this way It crosses first pipe to be conveyed to the hot-air of extraction in the plate heat exchanger of fluid bed granulator connection, while carrying out work in vacuum pump It can also generate heat when work, when being vacuumized, also be able to carry out preheated air to a certain extent;Vacuum pump extraction Air themperature it is higher than the air themperature for being directly entered plate heat exchanger so that hot-air is recycled, reached energy conservation Purpose.
5. the utility model storage bin volume is greater than slow feed bin volume, the charging rate of feed inlet is less than the discharging of discharge gate Speed, setting, which can be avoided residue material in storage bin and excessively influence equipment, so normally discharges.
