Abstract

The utility model discloses an ash conveying device which is characterized in that a blow-down pipe (7) is arranged at the front end of a main air inlet valve (5) of an air inlet valve set (1), and the blow-down pipe (7) is communicated with an ash conveying pipeline (2) through a plurality of gulp valve components (3). The gulp valve components (3) are added on the ash conveying pipeline (2), multipoint air supplementation is adopted, it is guaranteed that when dry ash is large in particle size or high in water content, ash can flow at low flow rate and can not block the pipeline, due to the low flow rate, the pipeline is slightly abraded, and the service life of a common seamless steel pipe can be more than 8 years. Moreover, due to the low flow rate, system air consumption amount is greatly lowered, and energy consumption is lowered.

Description

A kind of ash conveying device

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 ash conveying device 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 air-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 move by low flow velocity, and can plugging, because flow velocity is low, pipe wear is especially little simultaneously, 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

Below in conjunction with drawings and Examples, the utility model is further illustrated.

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

By reference to the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, basic structure of the present utility model is only described in a schematic way, so it only show the formation relevant with the utility model.

As shown in Figure 1, a kind of ash conveying device, 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 air-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 above-mentioned foundation desirable embodiment of the present utility model of take is enlightenment, and by above-mentioned description, relevant staff can, within not departing from the scope of this utility model technological thought, carry out various change and modification completely.The technical scope of this utility model is not limited to the content on specification sheets, must determine its technical scope according to claim scope.
