Abstract

The utility model discloses a pneumatic hoist. The pipe mouth at the lower part of the feeder tube is fixedly inserted in a sealed boiling box. A feeding column is fixed on the boiling box. The boiling box is provided with a boiling plate which isolates the boiling box into an upper space and a lower space and can be ventilated. The cavity under the boiling plate is a gas cell. The gas cell is provided with a transporting air tube and a boiling air tube which are communicated with the inner cavity. A nozzle is arranged on the boiling plate. The pneumatic hoist has simple structure, easy installation and can save the project investing cost without exercise means. The pneumatic hoist can sharpen the peak and fill the valley at the condition that the feeding is not uniform. The pneumatic hoist can be normally operated in the designed transport quantity range. The pneumatic hoist is not easy to collapse. The pneumatic hoist has low energy consumption, low requirement to the air source, operation expense saving, high reliability, good seal performance and reduces the maintenance and improves the working environment and reduces the labor intensity and the labor staff.

Description

Air hoist

Technical field:

The utility model relates to a kind of air hoist of vertical transport granular goods, and particularly a kind of feedway that is used for aluminium industry aluminium oxide vertical transport belongs to granular material conveying technology field.

Background technology:

In commercial production, the vertical-lift of powder is a requisite important step in the technological process.Lifting means has multiple, wherein uses bucket elevator the most generally, and the shortcoming of this kind equipment is: complex structure, poor sealing performance, to manufacturing, processing, installation requirement than higher, maintenance workload is big; And another kind of lifting means commonly used is a head tank, though this equipment is simple in structure, be easy to install, and the delivery pressure height, the energy consumption height can only be made intermittently defeated material.Because in electrolytic aluminium factory aluminium cell flue gas dry cleaning engineering, sack cleaner filters the aluminium oxide that gets off and need continuously rise in the aluminum oxide warehouse, so require lifting means reliable, safeguards simple, energy continuous feed and discharge, energy consumption is low as far as possible.And lifting means of the prior art still can not satisfy the needs of producing use.

Summary of the invention:

The purpose of this utility model is: provide a kind of simple in structure, reliable and energy consumption is low, the air hoist of vertical transport granular material continuously, to overcome the deficiencies in the prior art.

The utility model is to constitute like this: it comprises feed pipe (6), the lower end mouth of pipe of feed pipe (6) fixedly is inserted in the leak free boiling case (2), on boiling case (2), be fixed with one and add stock column (1), in boiling case (2), be provided with the case (2) that to seethe with excitement and be isolated into two spaces and boiling plate that can breathe freely (3) up and down, the cavity of boiling plate (3) below is air chamber (4), on air chamber (4), be provided with the conveying air pipe (7) and the boiling air pipe (8) that communicate with its inner chamber, nozzle (5) is installed on boiling plate (3); Boiling plate (3) is ventilative canvas plate; Be provided with level-sensing device mounting interface (9) on the stock column (1) adding; The side of boiling case (2) is provided with inspection door (10); On boiling air pipe (8), a control cock (11) is installed.

Owing to adopted technique scheme, the utility model compared with prior art the utlity model has simple in structure, reliable and energy consumption is low, the advantage of vertical transport granular material continuously.When using the utility model, to carry air pipe (7) to receive on the low-pressure gas source pipeline earlier, to add stock column (1) is connected with the alumina material delivery pipe, during work, when low-pressure air through air chamber, boiling plate feeds the aluminium oxide fluidization that alumina layer makes adding, the aluminium oxide flowing power increases, in horizontal flow on the boiling plate near nozzle, low-pressure air is ejected in the converying feeding tube at a high speed from nozzle, a large amount of air around the drainage nozzles, near nozzle, form zone of negative pressure, near the aluminium oxide the nozzle is attracted to nozzle center, enter in the converying feeding tube with the air that sprays and carry.

The utility model compared with prior art, the utility model does not have moving member, and is simple in structure, easy for installation, can save engineering investment cost; The body volume is big, and under the uneven situation of supplied materials, but peak load shifting guarantees the normally operation in the design range of throughput of air-lift unit function, is not easy the bed that collapses; Energy consumption is low, carry with low-pressure air (＜100kPa) provide by Roots blower or other blowing engines, less demanding to air source, being easy to provides, and can save over-the-road expense; Energy continuous feed and discharge, the reliability height, good seal performance reduces and safeguards, can obviously improve working environment and reduce labour intensity, has advantages such as the corresponding minimizing expense of minimizing staff expenditure simultaneously.

Accompanying drawing 2 is the A-A view of accompanying drawing 1;

Accompanying drawing 3 is the B-B view of accompanying drawing 1.

The specific embodiment:

Embodiments of the invention: during making, the lower end mouth of pipe of feed pipe (6) fixedly is inserted in the leak free boiling case (2), and converying feeding tube (6) extended be connected to aluminum oxide warehouse, air-driven chute bonded assembly under of the prior art and the sack cleaner is added stock column (1) to be fixed on the boiling case (2), it adds the height of stock column (1) and converying feeding tube (6), the character and the hoisting depth of aluminium oxide when bore can be according to concrete use, situations such as distance are determined by orthodox method, the case (2) that will seethe with excitement is installed in boiling case (2) is isolated into two spaces and boiling plate that can breathe freely (3) up and down, making the cavity of boiling plate (3) below is air chamber (4), boiling plate (3) can adopt the ventilative canvas plate of three to five layers of canvas to make, go up conveying air pipe (7) that communicates with its inner chamber of installation and a boiling air pipe (8) at air chamber (4), to carry air pipe (7) and boiling air pipe (8) to be connected to the Roots blower discharge pipe respectively, its caliber is according to carrying amount of air to determine, and, be negative pressure air pressure is regulated and guarantee in the body at the upward installation control cock (11) of air pipe (8) that seethes with excitement; At boiling plate (3) nozzle (5) go up to be installed, the bore of nozzle (5) can be definite by orthodox method with the spacing of converying feeding tube (6) and the aluminium oxide character of being carried and situations such as hoisting depth, distance according to it; In order to measure conveniently, the upward mounting interface (9) of a level-sensing device of making of stock column (1) can added; Easy for installation in order to overhaul, can (10) at inspection door of the side of boiling case (2) making.
