Abstract
The present invention relates to a device which is arranged on an asphalt distributor for asphalt road construction and maintenance and is used for clearing residual asphalt in a pipeline. In order to utilize a method of using compressed air at certain working pressure for clearing the residual asphalt in the pipe, the present invention is arranged. The present invention is composed of a power machine, an asphalt pump, an air compressor, an air storage cylinder, a distributing valve, a valve, the pipeline, a spray head, etc. The method and the device are used for clearing the residual asphalt in the pipeline after asphalt is distributed, and one person can complete the operation within 2 to 3 min. The present invention has the advantages of time saving, labor saving, economy and reliability.
Description
The present invention is equipped on a kind of dark-coloured pavement machinery-bituminous distributor of asphalt roads construction and maintenance, is used to remove the method and apparatus of residual bitumen in the pipeline.
Bituminous distributor is when distributing asphalt, and the operating temperature of pitch is 160 ℃～180 ℃, when spilling the cloth stop, also has some residual bitumens to exist in the pipeline, these pitches such as untimely disposing, and the very fast cooling of meeting is solidified in pipeline, causes pipeline and nozzle to block.The bituminous distributor of domestic manufacturer's production at present, generally be to be equipped with diesel fuel tanks, diesel pump, come residual bitumen in the pipe blow-through with diesel oil, this cleaning method cost is very high, and cleaning once needs with diesel oil about 40 kilograms, and energy waste is serious, labor intensity of operating personnel is also bigger, during cleaning, general two people need spend about two hours and just can finish, and still stopping state can take place.
The objective of the invention is to avoid above-mentioned weak point of the prior art, and provide a kind of easy, economy, efficient high in order to remove the method and apparatus of residual bitumen in the bituminous distributor pipeline.
The present invention drives bitumenpump and air compressor respectively by engine and transmission device, air compressor is imported air storage chamber with compressed air through pipeline, for adjusting and control the operating pressure of air storage chamber compressed air, be provided with gas circuit between air storage chamber and the air compressor in addition, on this gas path pipe, be provided with Pneumatic controller, compressed-air actuated operating pressure is adjusted to 4 * 10
4Pa～25 * 10
4Pa.Air storage chamber links by gas path pipe and distributing valve, and bitumenpump also links by pitch oil line pipe and distributing valve, and distributing valve is connected with nozzle by pipeline again.Handle distributing valve, can connect or seal the pitch oil circuit, connect or closed compression air gas circuit.After pitch sprinkling is intact, handle distributing valve, the pitch oil line pipe that sealing communicates with bitumenpump is connected the compressed air gas path pipe, makes the compressed air that reaches operating pressure pour the pitch sprinkling pipeline, and the residual bitumen of ot-yet-hardened in the pipeline is discharged from nozzle.Green grass or young crops is discharged from nozzle.
Above-described compressed-air actuated optimum working pressure is 8 * 10
4Pa.
Accompanying drawing 1 is the assembly of devices of the present invention and the course of work, is described in detail as follows:
Engine (1) drives bitumenpump (12) by transmission device (13), drive air compressor (3) by transmission device (2), air compressor and gas receiver (7) link with pipeline, establish a gas path pipe between gas receiver and the air compressor in addition, on this pipeline, be provided with air pressure regulator (5), form Pneumatic controller jointly with the pressure loosening valve (4) on the air compressor top cover; Gas receiver (7) links by pipeline and distributing valve (10), is provided with gas circuit valve (8) on this pipeline; Distributing valve (10) connects with nozzle (11) and bitumenpump (12) respectively by pipeline.
Above-described gas receiver (7) is provided with safety valve (6), and is connected to pressure meter (9), can be single work, and work on demand also can be together in series two or more gas receivers.
Accompanying drawing 2 is composition and work sheets of distributing valve (10), is described in detail as follows:
One side of valve body (28) has pitch inlet hole (26), opposite side has compressed air inlet hole (20), stifle (18) is passed on the top of valve rod (19), connect control crank (30), the place, axle center of valve rod (19) has axial long hole (25), also have a through hole (27) on the valve rod (19), communicate with the duct (23) of axial long hole (25), lower stifle (24). Bonnet, (18), bottom flange (24) are connected with bolt (22) pad (21) with valve body (28), and gasket seal (29) is equipped with in the junction. When rotation valve rod (19), make pitch inlet hole (26) and stem through-hole (27) when communicating, the operating position during for distributing asphalt and path, the work pitch of getting from bitumenpump (12) sprays from nozzle (11) through pipeline and this path. When stem through-hole (27) being turned to compressed air inlet hole (20) when communicating, the pitch inlet hole seals, and the compressed air gas circuit is connected, and compressed air pours the asphalt distribution pipeline and removes residual bitumen.
In reset procedure, if once do not clean up, can remove two to three times by continuous punching, concrete grammar is (seeing accompanying drawing 1): after the first time, removing work was finished, valve-off (8) started Engine (1) makes the rapidly full compressed air of storage of gas receiver (7), when treating that Pressure gauge (9) pointer arrives the operating pressure position, can open valve (8) and again remove.
After all removing work are finished, must valve-off (8), rotate distributing valve valve rod (19), the operating position when making distributing valve be in distributing asphalt, when preventing next distributing asphalt, pitch enters gas path pipe, solidifies in gas circuit.
The present invention has solved the problem of residual bitumen blocking pipe after pitch sprinkling is finished substantially, has alleviated labor intensity of operating personnel.Adopt the present invention to remove, a people just can finish in two to three minutes like a cork, save time, laborsaving, work efficiency is high.
