Abstract
The utility model discloses a pneumatic ash conveying device which comprises an air inlet valve group (1) and an ash conveying pipe (2) and is characterized in that an air supplementing pipe (7) is led from the front end of a main air inlet valve (5) of the air inlet valve group (1) and communicated with the ash conveying pipe (2) through a plurality of air supplementing valve assemblies (3). The air supplementing valve assemblies (3) are arranged on the ash conveying pipe (2), multipoint air supplementation is adopted, low-flowing-speed operation can be achieved when dry ash granularity is large or the dry ash water content is high, and the dry ash cannot block the pipes. Meanwhile, due to the fact that the flowing speed is low, pipe abrasion is small, the service life of a common seamless steel pipe can reach over 8 years, system gas consumption is greatly reduced, and energy consumption is reduced.
Description
Technical field
The utility model relates to a kind of feedway, is specifically related to a kind of pneumatic ash conveying plant.
Background technology
Ash pipeline in traditional pneumatic ash transmitting system is that common solid drawn pipe is carried, when if dry ash granularity is larger or dry ash aqueous ingredients is large, when if common solid drawn pipe is pressed low flow velocity design and operation, especially easily plugging, causes pneumatic ash transmitting system normally not move.If while pressing high flow rate design and operation, pipe wear especially severe, system air consumption increases greatly.
Utility model content
Goal of the invention of the present utility model is: for the problem of above-mentioned existence, provide a kind of simple in structure, durable, cost is low, the pneumatic ash conveying plant of energy-saving safe.
The technical solution adopted in the utility model is such: comprise air inlet valve group 1 and ash conveying pipe 2, wherein from master air suction valve 5 front ends of air inlet valve group 1, draw a blowdown pipe 7, by several gulp valve assemblies 3, blowdown pipe 7 is communicated with ash conveying pipe 2.
Described air inlet valve group 1 is comprised of main valve 6, master air suction valve 5 and total gulp valve 4.
Total gulp valve 4 is housed on described blowdown pipe 7.
The two ends of described gulp valve assembly 3 are welded on respectively on blowdown pipe 7 and ash conveying pipe 2.
In sum, owing to having adopted technique scheme, the beneficial effects of the utility model are:
1, the utility model is simple in structure, durable, cost is low, safety and environmental protection.
2, adopt and on ash pipeline, add gulp valve assembly, adopt multiple spot tonifying Qi, in the time of can guaranteeing that or dry ash aqueous ingredients larger in dry ash granularity is large, can be low flow velocity operation, and can plugging, simultaneously because flow velocity is low, pipe wear is especially little, and common solid drawn pipe service life can be over 8 years.And because flow velocity is low, system air consumption reduces greatly, has reduced energy consumption.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present utility model.
Mark in figure: 1-air inlet valve group, 2-ash conveying pipe, 3-gulp valve assembly, the total gulp valve of 4-, 5-master air suction valve, 6-main valve, 7-blowdown pipe.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail.
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
As shown in Figure 1, a kind of high-efficient simple hot bellows, comprises air inlet valve group 1 and ash conveying pipe 2, wherein from master air suction valve 5 front ends of air inlet valve group 1, draws a blowdown pipe 7, by several gulp valve assemblies 3, blowdown pipe 7 is communicated with ash conveying pipe 2.
Further air inlet valve group 1 is comprised of main valve 6, master air suction valve 5 and total gulp valve 4.
Further on blowdown pipe 7, total gulp valve 4 is housed.
Further the two ends of gulp valve assembly 3 are welded on respectively on blowdown pipe 7 and ash conveying pipe 2.
Employing adds gulp valve assembly on ash pipeline, adopts multiple spot tonifying Qi, in the time of can guaranteeing that or dry ash aqueous ingredients larger in dry ash granularity is large, can be low flow velocity operation, and can plugging, simultaneously because flow velocity is low, pipe wear is especially little, and common solid drawn pipe service life can be over 8 years.And because flow velocity is low, system air consumption reduces greatly, has reduced energy consumption.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection domain of the present utility model.
