Abstract
The present invention is used to promote with the Pneumatic lift of separating particles shape material, is made up of motor, blower fan, separation chamber, expansion chamber, discharge nozzle, dust arrester and materail tube, it is characterized in that motor and induced-draught fan are directly installed on the gravity dumping device, the dividing plate of one lengthening is arranged between expansion chamber and the separation chamber, also add sleeve pipe and charging chassis at the materail tube place.The expansion chamber top is equipped with the friction lid.And the switch air-valve is housed on induced-draught fan.Floor space is little by 70%, saves raw material 70%, has the function of auto feed, and no dust pollution does not have surplus material, the reliability height, and long service life is the renewal product of material lifting means.
Description
The present invention relates to the lift-on/lift-off type elevator,, simultaneously impurity such as the stone that mixes in the material, ironware, foreign material, dust are made the Pneumatic lift of automatic separating treatment especially for the lifting of graininess grain (paddy, wheat, corn, rice etc.).
In the prior art, Pneumatic lift comprises surface-based blower fan and motor, blast pipe, air intake duct, sieve sheet, gravity dumping device (separation chamber, expansion chamber), discharge nozzle, dust arrester and materail tube.Power needs the 4KW motor, and floor space is big.In addition, because will be from ground to the separation chamber and dust arrester, needing several meters long blast pipe and air intake duct, long distance air-supply increases the resistance of wind.Also be provided with the sieve sheet in the separation chamber, often stop up easily, need often pull down cleaning, and the material receiver part then needs the special messenger to control.
The objective of the invention is to overcome above shortcoming, provide a kind of occupation of land little, fitting operation is convenient, and power saving economizes raw-material Pneumatic lift again.
The present invention finishes as follows: with motor be directly installed on the gravity dumping device after induced-draught fan is connected, the gravity dumping device comprises separation chamber and expansion chamber, cancels original sieve sheet in the separation chamber, and the impeller working face of blower fan is communicated with the separation chamber.The switch air-valve of control air door air quantity size also is installed, so that handle on induced-draught fan.The dividing plate that one lengthening is arranged between expansion chamber and separation chamber.It is cone-shaped that dust arrester makes down little last great achievement, and the upper end also is provided with exhaust outlet.Put one section outer tube in the materail tube lower end, leave the space between the two, the inspiration from top to bottom of this air, outer tube also joins with the charging chassis.Vertical section also be installed at the expansion chamber top be and circular-arc make certain thickness friction lid by high-abrasive material, make graininess grain through friction after, the impurity dust is separated with it.
The present invention has following advantage compared with the prior art: 1. motor directly is connected with the separation chamber with blower fan, be directly installed on the gravity dumping device, the resistance of wind significantly reduces, the material decrease speed is accelerated, reduce the power that uses, originally need the motor about 4KW, now as long as 0.5-1.1KW saves electric power energy more than 1 times; 2. need not sieve sheet, reduce the trouble that wind-force gets clogged, not need frequent cleaning; 3. reduce many airducts, therefore save raw material 50-70%; 4. material receiver does not need the personal management, and after finishing using, not surplus material in the blanking hole is not so the blanking hole needs so dark yet; 5. floor space is than original little by 70%; 6. no dust pollution, foreign material such as iron nail, stone can be separated automatically; As the working machine (rice mill etc.) that joins with discharging opening break down, then material can stop up until dividing plate, cross-ventilation disappears, at this moment material sucking port can stop suction automatically, and is normal as working machine, then material sucking port can automatic suction.
Below in conjunction with accompanying drawing the present invention is described in detail.
Fig. 1 is a stereogram of the present invention.
Fig. 2 is a cutaway view of the present invention.
With reference to Fig. 1, Fig. 2, induced-draught fan (1), motor (2) directly are connected with gravity dumping device (3), impeller (19) workbench communicates with separation chamber (18) in the gravity dumping device (3), and on separation chamber (18) shell, can be provided with an observation window (7), the situation when being used to observe work.Be connected with ring flange between discharger (3) and the discharge nozzle (5) or joint (4) connects, also have a pressure door (6) at the port of export of discharge nozzle (5).On the blast pipe of induced-draught fan (1), be connected with dust arrester (11) with joint (8).Exhaust outlet (9) is also installed on dust arrester (11) top, and the bottom is outlet (12).Materail tube (14) has joint (10) to be connected with expansion chamber (17), and materail tube (14) is with a sleeve pipe (15) outside the lower end, and is gapped between the two, and the size in gap is for being not more than the radius of materail tube (14), and its lower end and charging chassis (16) join.
As shown, the impeller (19) in actuating motor (2) drive induced-draught fan (1) then air is sucked into, and the air some flows to the gap between materail tube (14) and material receiver outer tube (15); Another is partly come in from charging chassis (16), drives graininess grain and enters materail tube (14) until expansion chamber (17), vertical section is installed at expansion chamber (17) top is circular-arc to make certain thickness grinding disk by high-abrasive material.Material is in operation and grinding disk rubs.In the time of then through separation chamber (18), be depressurized buffering, material descends by gravity, and foreign material such as dust then are sucked into dust arrester (11).Between separation chamber (18) and expansion chamber (17),, and be angled 50-55 ° with level original dividing plate lengthening 23Cm.So just can save the sieve sheet, with material after the air separation by the pressure door discharging.Dust arrester (11) makes up big and down small bullet.It is the W shape that charging chassis (16) makes vertical section, and outwards the tub wall that stretches becomes 40 ° of left and right sides angles with level, helps the inspiration of material.
Grinding disk can be made by high-abrasive materials such as diamond dust or cast iron or white iron.At induced-draught fan (1) the switch air-valve of being controlled air quantity by handle (13) is housed, so that manually control.
Because induced-draught fan (1) directly is contained on the gravity dumping device (3) with motor (2), dwindled the air channel, reduced resistance, therefore, adopts 0.5-1.1 kilowatt of the power selection of motor (2), just can replace the motor about 4KW, hoisting depth still can reach 3-6 rice, and material promotes conveying capacity can reach 1-3t/h.
