Abstract
The utility model relates to a powder material flexible pneumatic conveyer which has the main technical characteristic that the powder material flexible pneumatic conveyer is composed of a hopper, a feed valve, a sender, a pressure transmitter, an air inlet pipeline and a conveying pipeline, wherein the pressure transmitter is arranged on the air inlet pipeline and a proportion regulation valve is arranged on the air inlet pipeline between the pressure transmitter and the air inlet valve. Due to the fact that the utility model is added with the proportion regulation valve which is automatically controlled by PLC, when the materials are conveyed, the air inflow is regulated according to the variation of the air pressure in the pipeline through that a computer controls the opening of the proportion regulation valve, which causes the conveying status and the conveying speed of the material in the pipeline to reach the best, therefore the material conveying problem with large conveying capacity and long distance is perfectly solved and high material conveying capacity and uniform conveying speed are realized. The utility model has the advantages of long service life and simple operational maintenance, and effectively raises work efficiency.
Description
Technical field
The utility model belongs to ducting, the flexible Pneumatic conveyer of especially a kind of granular material.
Background technology
For the conveying of granular material, adopt pneumatic conveying method in the world mostly at present.Now the pneumatic conveying method of Shi Yonging is to be unmodified substantially in various transportation parameters, and feed status is fixed.This just requires transport condition constant substantially, and this condition is feasible basically abroad, and, boiler operatiopn state constant as fire coal is constant etc.Can be in China, the real-world operation state is unsettled, as coal-fired quality instability, ash and product ash amount have very big variation etc.In addition, the boiler operatiopn load is unstable also very big for the influence of producing the ash amount, and phenomenons such as enhance faster wear, plugging can appear in the normal operation that this will influence air-transport system.And air-transport system is introduced from external each company, some air-transport systems just occurred normally to move abroad, and the phenomenon that just often breaks down at home.
It generally is to adopt air as delivering gas that strength is carried, and material seals conveying in pipeline, and material is compressed into pipeline carry.In course of conveying, pipeline air pressure makes material form a material bolt in pipeline, delivering gas promotes this material bolt and moves, until being transported to grey storehouse, minimum being greater than 30: 1 of solid-gas ratio that fitness for purpose is carried, be but that per kilogram delivering gas convey materials is more than 30 kilograms, when fed distance reached 100 meters, solid-gas ratio can reach 80: 1.Yet, increase along with fed distance, material formed material bolt in pipeline scatters easily, required delivery pressure increases simultaneously, air consumption, delivery speed all can strengthen, and the pipeline friction force is increased, and economy reduces, and plugging takes place probably, so that carry failure when parameter of materials changes.Tracing it to its cause, mainly is that formed material bolt is shorter in the 1. present pipelines, and the material bolt is dispelled easily; 2. carry air pressure to fix, the material bolt is fixed and is shorter, in case that pipeline when resistance state (especially channel bend, rise and fall etc. different) occurs is unusual, the pipeline internal gas pressure can not be regulated, and pipe choking is then inevitable.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of simple in structure, can change the flexible Pneumatic conveyer of granular material of automatic compensation suction quantity according to the pipeline internal gas pressure.
The utility model solves its technical matters and takes following technical scheme to realize:
The flexible Pneumatic conveyer of this granular material, constitute by hopper, inlet valve, transmitter, pressure transformer, induction tract, delivery duct, pressure transformer is installed on the induction tract, on this induction tract, air inlet valve is installed, it is characterized in that: a ratio adjusting valve is installed on the induction tract between pressure transformer and the air inlet valve.
And described ratio adjusting valve is an electric-controlled ball valve.
Advantage of the present utility model and good effect are:
Increased by PLC automatically controlled ratio adjusting valve, make the air pressure that enters pipeline can automatically regulating, the length of material bolt can be done longlyer as required, gas fully mixes and reaches the solid-gas ratio of the best with material, adjust suction quantity according to the variation of pipeline internal gas pressure and by the aperture of computer controlled ratio adjusting valve during mass transport, make feed status and the delivery speed of material in pipeline reach best.The utility model has ideally solved big operational throughput, remote mass transport problem, has realized that the mass transport ability is big, and delivery speed is even, long service life, and operating maintenance is simple, has improved work efficiency effectively.
Description of drawings
Fig. 1 is an overall structure scheme drawing of the present utility model;
Fig. 2 is the structure enlarged drawing of the induction tract of Fig. 1.
The specific embodiment
Below in conjunction with accompanying drawing the utility model embodiment is further described:
The flexible Pneumatic conveyer of this granular material is applied in the air-transport system, and its principle of work is: adopt pneumatic mode to be transported to grey storehouse 1 by delivery duct 2 through inlet valve 4, transmitter 5 granular material in the hopper 3.The pneumatic mode that is adopted is to be coaxially installed with an induction tract 8 at the discharging opening place of transmitter and discharging opening, this induction tract is by source of the gas 10 (comprise storage tank, Air compressor and other similar pressed gas generating meanss, present embodiment is represented with " source of the gas " in the accompanying drawings).On this induction tract, begin to be installed into successively air valve 9, ratio adjusting valve 7 and pressure transformer 6 from source of the gas.This ratio adjusting valve is installed on the induction tract between pressure transformer and the air inlet valve, and this ratio adjusting valve can adopt electric-controlled ball valve, perhaps also can adopt the electric check valve of similar functions etc.
In this device, valve such as ratio adjusting valve and inlet valve all adopts PLC program editor automatic guidance, pressure in the delivery duct (can comprise several spot pressures) is by the pressure transformer collection, pressure transformer is delivered to the PLC program editor with the signal that collects, this program editor will be the size of suction quantity by the aperture size of the programming control ratio adjusting valve that presets, regulate pressure in the delivery duct with this.Like this, just can control the length of material bolt of granular material and the degree of uniformity of delivery speed, improve mass transport efficient, and effectively solve the plugging problem of delivery duct.
Claims (2)
1. the flexible Pneumatic conveyer of a granular material, constitute by hopper, inlet valve, transmitter, pressure transformer, induction tract, delivery duct, pressure transformer is installed on the induction tract, on this induction tract, air inlet valve is installed, it is characterized in that: a ratio adjusting valve is installed on the induction tract between pressure transformer and the air inlet valve.
2. the flexible Pneumatic conveyer of granular material according to claim 1, it is characterized in that: described ratio adjusting valve is an electric-controlled ball valve.
