Description
Technical field
A kind of Geldart-D particle plug-back device is the utility model is related to, specially a kind of pipe valve component, coordinates plug-back operation, it is real
Existing flow delivery systems pipe-dredging.
Background technology
The features such as Geldart-D particle because its is simple in construction, easy to operate, conveying capacity is big, fed distance length, and transporting velocity is high, extensively
It is general to be applied to the fields such as thermoelectricity, chemical industry, pharmacy, food.But in practical application, often because of originals such as technological operation is improper, equipment faults
The plugging caused by, often it is in concealed location or eminence, and transfer line length is moved on then due to feed-line aesthetically
Hundred meters, or even upper km, once blocking, the inconvenience of plugging point position is searched, more seriously when induction system blocks,
Often very long pipeline section thoroughly blocks, and can not be discharged by single-point, be properly completed block clearing, can only choose multiple point positions and carry out pipe cutting
Block clearing, waste time and energy, the cost of overhaul is high, and the material of block clearing discharge is not easy to collect again, causes environmental pollution, influences existing
Personnel health and material is caused largely to waste.
Utility model content
Technical problem to be solved in the utility model is：A kind of Geldart-D particle plug-back device is provided, can solve strength
It is simple and reliable after conveying blocks the shortcomings that block clearing difficulty.
Technical scheme is used by solve above-mentioned technical problem the utility model：Geldart-D particle plug-back device, including
Main pipeline, main pipeline one end is compressed air interface, the other end is conveyance conduit interface, is connected with branch pipe in the middle part of main pipeline, props up
Plug-back valve is provided with pipe, pressurizing valve and pressure gauge are provided with main pipeline, pressurizing valve connects located at compressed air interface and branch pipe
Between contact, pressure gauge is located between conveyance conduit interface and branch pipe tie point.
Pressurizing valve and plug-back valve preferably use ball valve, can be achieved to change up pass soon.
During implementation, corresponding connection compressed air and conveyance conduit, branch pipe are vented or are connected to feed bin respectively at main pipeline both ends,
After the completion of device connection, under conveyance conduit stopping state, plug-back is carried out by the following method：
1) pressurizing valve is opened, observes pressure gauge, until pressure no longer goes up, or by listening, until without air in pipe
Flow sound, you can close pressurizing valve；
2) open plug-back valve and pressure release is carried out to pipeline, until air drains in pipeline, gauge hand zero；
3) plug-back valve is closed, pressurizing valve pressurization is again turned on, operates repeatedly as above, until under pressurized condition, pressure
Power table instruction pressure only slightly goes up, and now pipeline is thoroughly dredged.
The beneficial effects of the utility model are：It is simple and reasonable, it is cheap, it is a kind of simple and practical device, is
Perfect innovation to conventional art.The utility model have the characteristics that it is safe and applicable, have well promote and practical value, extensively
Good Social benefit and economic benefit can be produced after popularization.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model；
Marked in figure：1- main pipelines, 2- branch pipes, 3- pressure gauges, 4- pressurizing valves, 5- plug-back valves.
Embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings.
As shown in figure 1, the utility model can use a T-shape steel pipe, also one can be welded on one section of main pipeline 1
Branch pipe 2, steel pipe material are respectively equipped with adpting flange preferably with seamless steel pipe, steel pipe end, if do not used flange to connect, also may be used
Directly weld.One end of main pipeline 1 sets ball valve one, and for being pressurizeed to conveyance conduit, referred to as pressurizing valve 4, end are used for outer
Connect source of the gas；The other end of main pipeline 1 sets 3 one pieces of pressure gauge, and for observing conveyance conduit pressure change, end is defeated for connecting
Send pipeline；Ball valve one is also provided with branch pipe 2, for pressure discharge operations, referred to as plug-back valve 5, end can tieback to feed bin, be easy to receive
Collection blocks material, also can directly be vented.The effect of ball valve mainly can be achieved to change up pass soon, and diameter of steel tube is big according to conveyance conduit
Depending on small, typically about 1/2 pipe diameter, caliber is bigger, and service speed is faster.External gas source uses compressed air, pressure
Power is higher, and plug-back ability is stronger.
After the completion of device connection, under conveyance conduit stopping state, plug-back is carried out by the following method：
1) pressurizing valve 4 is opened, observes pressure gauge 3, until pressure no longer goes up, or by listening, until without sky in pipe
Flow of air sound, you can close pressurizing valve 4；
2) open plug-back valve 5 and pressure release is carried out to pipeline, until air drains in pipeline, the pointer of pressure gauge 3 zero；
3) plug-back valve 5 is closed, pressurizing valve 4 is again turned on and pressurizes, operate repeatedly as above, until under pressurized condition,
Pressure gauge 3 indicates that pressure only slightly goes up, and now pipeline is thoroughly dredged.
