Abstract

The invention relates to a buffer-typed pneumatic lifter. The buffer-typed pneumatic lifter essentially consists of a motor 1, an air blower 2, a discharger 5, a dust collector 12, a pressure discharging tube 6 and a material acceptor and is characterized in that the air blower 2 which is connected with the motor 1 is directly installed at the center of the top part of the discharger 5; a feeding tube consists of a buffer tube 7 of an upper section and an accelerating tube 8 of a lower section, a feeding base 10 is arranged under the accelerating tube 8 and is provided with a plurality of air inlets 20 and a plurality of feeding ports 21; an adjusting disc 17 of the end port of the feeding base 10 is fixed on a ground fixed disc 18 inside a material accepting disc 11, and the lower end of an outer sleeve 9 is also provided with feeding ports 22 which are matched with the feeding ports 21 mutually. The buffer-typed pneumatic lifter has the advantages that (1) the pressure of the materials can be quickly reduced after being buffered by the buffer tube 7 after the accelerating lift of the accelerating tube 8, therefore, the impact between the materials and the top part of the discharger is reduced and the crushing rate of the material is effectively reduced; (2) wind speed is lowered after the material is buffered by the buffer tube 7, the resistance of wind pressure is decreased and wind resistance loss is reduced; (3) since the weight of the whole machine is fixed on the ground fixed disc, the gravity center of the whole machine is stable, the lifter is not needed to be hung on the beam of a house by an iron wire, and the usage is safe and reliable.

Description

Buffering type air hoister

Technical field

The present invention relates to be used for a kind of buffering type air hoister that the material of graininess (paddy, wheat, brown rice, corn and feed etc.) promotes.

Background technology

The patent No. of the prior art is that the material-receiving device on 90221521.3 the Pneumatic lift mainly is made up of feed pipe and outer tube; Connection between it and structure are: outer tube lower end and charging chassis join and are installed in and pile up in the blanking hole that granular material is arranged, feed pipe upper end is communicated with discharger on the gig, insert in the outer tube lower end of feed pipe, gapped between feed pipe pipe outer wall and the outer tube inside pipe wall, cause feed pipe can't be stably fixed at ground, so discharger that is attached thereto, electrical motor on the discharger, the weight of the complete machine of the Pneumatic lift that blower fan and dirt collector are formed can only be lifted on the crossbeam in house with iron wire, when Pneumatic lift is worked, because the running that electrical motor and blower fan do not stop, of long duration will make the displacement of Pneumatic lift discharger, cause the wearing and tearing and the damage of feed pipe easily, originally feed pipe does not have air and material concentration to compare regulatory function, not high to the inconsistent lifting effectiveness that will cause of different material proportion, the waste kinetic equation loss.In addition, because thickness is the same up and down for feed pipe, not only cause windage, and Pneumatic lift per second speed more than 20 meters when promoting, speed about granular material enters in the feed pipe is constant, granular material clash into severely owing to speed in discharger too soon, causes that material is injured to be increased with percentage of damage.

Summary of the invention

The objective of the invention is at the shortcoming on the Pneumatic lift in the above prior art, can be on the ground and provide that design is a kind of with the weight held stationary of Pneumatic lift complete machine, need not Pneumatic lift is hung on the crossbeam, lifting efficient can be effectively improved, and a kind of buffering type air hoister of granular material percentage of damage can be reduced.

The technical scheme of buffering type air hoister of the present invention is: a kind of buffering type air hoister, mainly constitute by electrical motor 1, blower fan 2, discharger 5, the dirt collector 12 that is installed in discharger 5 one sides, pressure discharge nozzle 6 and the material receiver formed by feed pipe and outer tube, it is characterized in that: be directly installed on the top center of discharger 5 with electrical motor 1 bonded assembly blower fan 2, the below that draught fan impeller 146 is connected discharger 5 also communicates with the operating room of discharger 5; Feed pipe is made up of the buffer tube 7 of last joint and the accelerating tube 8 that saves down, buffer tube 7 upper ends are communicated with the discharger 5 of gig, accelerating tube 8 belows are provided with one and are provided with several admission ports 20, have the charging seat 10 of several inlet points 21, charging seat 10 ports are provided with an adjustment disk 17, adjustment disk 17 usefulness screws are fixed on cement and are fixed on the ground reaction plate 18 in the receiver 11, outer tube 9 is enclosed within outside the charging seat 10 of accelerating tube 8 belows, gapped between outer tube 9 inside pipe walls and the accelerating tube 8 pipe outer walls, outer tube 9 lower ends are also corresponding to be provided with the inlet point 22 that the inlet point 21 with charging seat 10 cooperatively interacts.

(1) material quickens to promote at accelerating tube 8 after can rapid depressurization after buffer tube 7 bufferings, reduces the impulsive force at material and discharger top, can effectively reduce the percentage of damage of material.(2) material is low through buffer tube 7 buffering after wind prompt drops, the blast resistance force diminishes, and windage loss reduces, and effectively saves energy is more than 30 percent.(3) because charging seat 10, accelerating tube 8 and buffer tube 7 all adopt thick arm round steel pipe, can prolong more than 5 times service life.(4) weight of this machine complete machine is fixed on the ground reaction plate in the receiver 11 because of being fixed on cement, and machine gravity is stable, does not need to be lifted on the crossbeam in house with iron wire, and is safe and reliable.
