Technical field
The utility model relates to the anti-blocking equipment of a kind of pipeline, in particular for the anti-block apparatus of the course of conveying of Pneumatic ash conveying pipeline such as cement, coal dust, agstone.
Background technology
In existing Pneumatic Conveying Technology, the problem that always has the transfer line plugging, after transfer line generation plugging phenomenon, usually adopt the former block apparatus that manually blows that is installed on the pipeline to blow and thread a pipe, not only time-consuming but also require great effort, because transfer line is generally built on stilts the layout, blow the stifled ascend operation that needs again, poor stability, complex operation.Chinese patent ZL99252018.5 discloses a kind of pneumatic carrier road automatic block-resistant device, the technical scheme that solves is: mainly be made up of ash bucket and the coupled little storehouse of malleation concentrated phase pump, the little storehouse of malleation concentrated phase pump connects the source of the gas air inlet pipe, also be provided with ash pipeline, defeated meeting pipe be provided with the mechanical compression switch, the female pipe of the air that the ash pipeline side also is provided with and its balance is provided with.This technical scheme has realized the automatic block-resistant of pipeline substantially, but needs each ash pipeline correspondence that the female pipe of an air is set in the application of reality, and cost of installation is too high, and pressure switch directly links to each other with electromagnetic valve, and is stable not high.
Summary of the invention
The purpose of this utility model is a kind of high a kind of pneumatic carrier road anti-block apparatus rational in infrastructure, convenient for installation and maintenance, stable of design.The technical solution of the utility model is so to realize:
A kind of pneumatic carrier road anti-block apparatus, comprise delivery pipe, the female pipe of air, be located at the pressure sensor on the delivery pipe, connect the blowing tube of the female pipe of delivery pipe and air, blowing tube (11) one ends are communicated with the female pipe of air (8), the other end is connected with delivery pipe (9), blowing tube is provided with shutoff valve, electromagnetic valve and boiler check valve, and pressure sensor (6) is connected with electromagnetic valve (3) by PLC, is provided with slip joint (5) between electromagnetic valve (3) and boiler check valve (4).
As preferably, slip joint (5) one ends and blowing tube (11) flexibly connect, and other end boiler check valve (4) flexibly connects, and boiler check valve (4) is connected with delivery pipe (9) by blowing tube (11) end;
As preferably, the female pipe of blowing tube (11) near-space gas (8) one ends are provided with the flow regulating valve (2) of regulating charge air;

As preferably, blowing tube (11) is 20～60 degree with the angle a that delivery pipe (9) is connected to form, and makes the air that blowing tube (11) comes out and the direction basically identical of the interior MEDIA FLOW of delivery pipe (9);
As preferably, electromagnetic valve (3) is a bi-bit bi-pass air electromagnetic valve;
The utlity model has compact conformation, easy for installation, characteristics such as effect is good, be easy to apply.
Description of drawings
Accompanying drawing 1 is a kind of structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing,, the technical solution of the utility model is described in further detail by embodiment.
Embodiment: in conjunction with the accompanying drawings 1, pneumatic carrier road anti-block apparatus, the other female pipe of air in parallel (8) of establishing of delivery pipe (9), couple together by blowing tube (11) between female pipe of air (8) and the delivery pipe (9), the female pipe of blowing tube (11) near-space gas (8) one ends to delivery pipe (9) junction one end on, be provided with flow regulating valve (2) successively, shutoff valve (1), bi-bit bi-pass air electromagnetic valve (3), slip joint (5), boiler check valve (4), pressure sensor (6) is located in the pressure pipe (12) that is communicated with delivery pipe (9), pressure pipe (12) by welded and installed at nearly delivery pipe (9) and blowing tube (11) point of connection place, and communicate with delivery pipe (9), be that pressure sensor (6) institute measuring pressure is delivery pipe (a 9) internal pressure parameter, pressure sensor (6) is a metal diaphragm formula pressure switch, pressure sensor (6) is connected with electromagnetic valve (3) by PLC, thereby reaches the switch motion of control electromagnetic valve (3); Slip joint (5) one ends and blowing tube (11) flexibly connect, and other end boiler check valve (4) flexibly connects, and boiler check valve (4) is connected with delivery pipe (9) by blowing tube (11) is terminal; The angle a that blowing tube (11) and delivery pipe (9) are connected to form is 30 degree, changes angle effect basically identical, generally at 20～60 degree, makes the air that blowing tube (11) comes out and the direction basically identical of the interior MEDIA FLOW of delivery pipe (9); Shutoff valve (1) operated by rotary motion when safeguarding, is turn-offed shutoff valve (1) in opening, brings great convenience to maintenance.
During work, when delivery pipe (9) internal pressure reaches the upper pressure limit that PLC sets, pressure sensor (6) signals to PLC, outputs signal to electromagnetic valve (3) after PLC handles, and electromagnetic valve (3) is opened, and gives delivery pipe (9) air feed, destroys the condition that produces plugging; When reach the low pressure limit that PLC sets when delivery pipe (9) internal pressure, pressure sensor (6) signals to PLC, outputs signal to electromagnetic valve (3) after PLC handles, and electromagnetic valve (3) is closed, and stops delivery pipe (9) air feed.
