Abstract
The utility model discloses a pneumatic conveyor. The pneumatic conveyor comprises an accelerating chamber, wherein the accelerating chamber is connected with an air inlet pipe, a rotary feeder and a conveying pipeline respectively. A reversed air feeding pipe is arranged at the accelerating chamber, the accelerating chamber is connected with the air of the outside though the reversed air feeding pipe. The pneumatic conveyor is targeted at increasing the agitaion of the depositional material in the accelerating chamber, preventing the material from depositing, ensure that the material is not blocked at the place so that the smooth of the whole conveying pipeline is not influenced; the reversed air feeding pipe is simple in structure, easy to install and excellent in effect; and the install location of the reversed air feeding pipe is not much restricted so that the location can be chosen according to the real situation.
Description
Technical field
The utility model relates to a kind of chemical production equipment, relates in particular to a kind of Pneumatic conveyer that is used for powder conveying.
Background technology
One of load transfer device comparatively commonly used when Pneumatic conveyer is Chemical Manufacture, have simple in structure, technology arrangement flexibly, can control effectively when taking up an area of less, mass transport that dust flies upward, operational throughput big, simple operation and other advantages.This equipment mainly is made up of rotary feeder, accelerating chamber, delivery duct, whirlwind collector, bag dust collector, air suctiton ventilator, ventilation inlet, air sealer etc.After air suctiton ventilator starts, in pipeline, cause certain negative pressure, at this moment, just constantly sucked in the delivery duct from ventilation inlet at the air of pipeline outside.Meanwhile, material gets into accelerating chamber by rotary feeder, after mixing with suction air, via ducting to whirlwind collector, bag dust collector and consolidate, gas separates, material is again in air sealer is discharged to holding vessel; Separate clean air then in the air suctiton ventilator exhaust to atmosphere.
But; That Pneumatic conveyer also exists is higher such as consumption of power, the material performance of carrying is required shortcomings such as height, fed distance be limited; Particularly the subtle change of mass transport amount can both cause operational difficulty; Such as the normal powder conveying equipment of operation, when rotary feeder blanking amount has increase slightly, if can not in time correspondingly turn the blanking amount down or transfer big intake; Can cause suction air the material of entering accelerating chamber fully to be mixed and all take away, run up to so to a certain degree and just might stop up whole delivery duct.
Summary of the invention
Goal of the invention: the purpose of the utility model provides a kind of later-model Pneumatic conveyer, to solve the existing Pneumatic conveyer shortcoming not strong to the variation comformability of inventory, guarantees that material can not stop up at accelerating chamber, guarantees the unimpeded of whole delivery duct.
In order to solve the problems of the technologies described above, the utility model has adopted following technical scheme:
A kind of Pneumatic conveyer comprises accelerating chamber, and said accelerating chamber connects intake stack, rotary feeder and delivery duct respectively, and reverse secondary air channel road is set on the said accelerating chamber, and accelerating chamber is inner to be communicated with extraneous air through reverse secondary air channel road.
The utility model, further, said reverse secondary air channel road is arranged on the junction of accelerating chamber and delivery duct.
The utility model, further, the bore in said reverse secondary air channel road is smaller or equal to the bore of delivery duct.
The utility model, further again, be 30～45 ° angle between said reverse secondary air channel road and the delivery duct, and on the reverse secondary air channel road control cock be set.
Beneficial effect: 1) the utility model strengthens the agitaion to deposition material in the accelerating chamber targetedly, prevents the material deposition, thereby has influence on the unimpeded of whole delivery duct to guarantee that material can not stop up herein; 2) reverse secondary air channel road is simple in structure, installs easily, and action effect shows; 3) reverse installation site, secondary air channel road does not receive too big restriction, can select the position of installation according to actual conditions.
Description of drawings
Fig. 1 is the structural representation of existing Pneumatic conveyer.
Fig. 2 is the structural representation of the utility model.
The specific embodiment:
Below in conjunction with accompanying drawing the utility model is done explanation further.
As shown in Figure 1, existing Pneumatic conveyer will be made up of intake stack 1, rotary feeder 2, accelerating chamber 3, delivery duct 4, whirlwind collector 5, bag dust collector 6, air suctiton ventilator 7 and air sealer 10.Accelerating chamber 3 connects intake stack 1, rotary feeder 2 and delivery duct 4 respectively, and delivery duct 4 connects whirlwind collector 5, bag dust collector 6 and air suctiton ventilator 7 successively, and whirlwind collector 5 is connected storage tank 8 through air sealer 10 respectively with bag dust collector 6.
During work, air suctiton ventilator 7 starts, and in delivery duct 4, causes certain negative pressure, and the air of outside is just constantly sucked in the delivery duct 4 through accelerating chamber 3 from intake stack 1.Meanwhile, material gets into accelerating chamber 3 by rotary feeder 2, after mixing with suction air, via delivery duct 4 be transported to whirlwind collector 5, bag dust collector 7 and consolidate, the gas separation, material is again in air sealer 10 is discharged to holding vessel 8; Separate clean air then in air suctiton ventilator 7 exhaust to atmospheres.
When rotary feeder 2 blanking amounts have increase slightly; If can not in time correspondingly turn the blanking amount down or transfer the intake of big intake stack 1; Can cause suction air the material of entering accelerating chamber 3 fully to be mixed and all take away, run up to like this and to a certain degree just might stop up whole delivery duct 4.
As shown in Figure 2, the utility model is that reverse secondary air channel road 9 is set on accelerating chamber 3, and the accelerating chamber 3 inner reverse secondary air channel roads 9 that pass through are communicated with extraneous air.When the inventory that gets into accelerating chamber 3 becomes big suddenly; There is partial material possibly not have in time taken away and be deposited on accelerating chamber 3 bottoms by air; At this moment can be dispelled the material that is deposited on accelerating chamber 3 bottoms, blown open from the formed air-flow of reverse secondary air channel road 9 inlet airs; Make the material that is deposited on this be unlikely to cumulative, thereby ensure the unimpeded of whole delivery system.
Reverse secondary air channel road 9 preferably is installed in the junction near accelerating chamber 3 and delivery duct 4, is the place that obstruction takes place delivery duct 4 easily here, and the bore in reverse secondary air channel road 9 is smaller or equal to the bore of delivery duct 4.During installation, preferably there is 30～45 ° angle in reverse secondary air channel road 9 with main delivery pipe 4, and installs the valve of an adjusting usefulness additional, with convenient adjustment benefit air quantity.
The above only is the preferred implementation of the utility model; Should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; Can also make some improvement and retouching, these improvement and retouching also should be regarded as the protection domain of the utility model.
