Abstract

The utility model relates to a hoisting elevator which is an air-operated elevator particularly used for elevating and separating granular material. The utility model is composed of a motor, a blower, a separation chamber, a sedimentation chamber, a discharge pipe, a dust collector and a material pipe. The hoisting elevator is characterized in that the motor and the blower are directly connected with the separation chamber. Thus, an air channel is shortened, and a plurality of air pipes are saved. A sleeve pipe and a feeding base plate are added outside the material pipe, so material remaining phenomenon is avoided in the process of elevation. The machine can save electricity energy by more than one time. The utility model has the advantages of no sieve sheets, resistance reduction, the acceleration of the descending speed of material, and the enhancement of the economical benefit of the whole machine.

Description

Air-operated elevator

The utility model relates to the lift-on/lift-off type gig, especially for the lifting of graininess grain (paddy, wheat, rice, corn etc.), simultaneously impurity such as the stone that mixes in the material, ironware, foreign material, dust is made the Pneumatic lift of automatic separating treatment.

In the prior art, Pneumatic lift comprises surface-based blower fan and electrical motor, blast pipe, aspirate tube, sieve sheet, gravity dumping device (separation chamber, deposit chamber), discharge nozzle, dirt collector and materail tube.Power needs the 4KW electrical motor, floor area is big, in addition, because will be from ground to the separation chamber and dirt collector, need several meters long blast pipe and aspirate tube, long distance air-supply, the resistance of wind is increased, 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 needs then the special messenger to control.

The purpose of this utility model is to overcome above shortcoming, provides a kind of occupation of land little, and fitting operation is convenient, and power saving economizes raw-material Pneumatic lift again.

The utility model is finished as follows: with electrical motor be directly installed on the gravity dumping device after induced draft fan is connected, the gravity dumping device comprises separation chamber and setting chamber, cancels original sieve sheet in the separation chamber, and the impeller driving surface 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 draft fan.It is cone-shaped that the dividing plate that one lengthening is arranged between setting chamber and separation chamber, dirt collector make down little last great achievement, and the upper end also is provided with exhausr port.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 is installed at the setting chamber top is and circular-arc make certain thickness friction lid by high-abrasive material, after making graininess grain through friction, the impurity dust is separated with it.

The utility model has following advantage compared with the prior art: 1. electrical 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 descending speed is accelerated, reduce the power that uses, originally need the electrical 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 many raws MAT'L; 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.

Below in conjunction with accompanying drawing the utility model is described in detail.

Fig. 1 is the utility model block diagram.

Fig. 2 is the utility model cutaway view.

With reference to Fig. 1, Fig. 2, induced draft fan (1), electrical motor (2) and gravity dumping device (3) direct connection impeller (19) bench board communicate 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 flange connection or joint (4) between discharger (3) and the discharge nozzle (5), also have a pressure door (6) at the exit end of discharge nozzle (5).On the freeing pipe of induced draft fan (1), be connected with dirt collector (11) with joint (8).Exhausr port (9) is also installed on dirt collector (11) top, and the bottom is outlet (12).Materail tube (14) has joint (10) to be connected with setting 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 draft 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), drive graininess grain and enter materail tube (14) until setting chamber (17), vertical section is installed at setting chamber (17) top is and circular-arc 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, foreign material such as dust then are sucked into dirt collector (11), between separation chamber (18) and setting chamber (17),, and be angled 50-55 ° with level original dividing plate lengthening 23Cm.So just can save the sieve sheet.Pass through the pressure door discharging with the material after the air separation.Dirt collector (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 emery powdor or cast iron or white pig irons, and the switch air-valve of being controlled air quantity by handle (13) is housed at induced draft fan (1).So that manually control.

Because induced draft fan (1) directly is contained on the gravity dumping device (3) with electrical motor (2), dwindled the air channel, reduced resistance, therefore, adopts 0.5-1.1 kilowatt of the power selection of electrical motor (2), just can replace the electrical motor about 4KW, hoisting depth still can reach 3-6 rice, and material promotes operational throughput can reach 1-3t/h.
