Detailed description of the invention
The utility model proposes the new equipment of a kind of waste filling dredging plugging, in order to make the purpose of this utility model, technical scheme and advantage become apparent from, clearly, below with reference to specific embodiment, the utility model is further described.
Shown in Fig. 1-4, the new equipment of a kind of waste filling of the utility model dredging plugging, mainly includes forced forcing press, pull-out type forcing press, pipeline control valve, rotating valve, valve roating sphere, filling pipeline, accident pulp-expelling valve, bridge piece, increasing resistance packing ring, fastening bolt, backup line.
Set the bolt hole of 4 φ 10mm at described each pipeline junction, by increasing resistance packing ring 5, pipeline is connected by fastening bolt 7.
When filling pipeline generation pipeline jam accident, first will be pressed into formula forcing press 1 by increasing resistance packing ring 5, fastening bolt 7 couples together with bridge piece 6 one end, is simultaneously connected with bend pipe 6 other end and is connected by increasing resistance packing ring 5, fastening bolt 7 with filling pipeline 4, thus it is airtight with upper pipe to realize forcing press.
During normal filling, described backup line 9 end is provided with accident pulp-expelling valve 8, its end is standing shape (as shown in Figure 4), this design increases pipeline and backup line inwall frictional force, improves pipeline explosion-proof during normal filling, it is ensured that filling security.
By accident pulp-expelling valve 8 removal when pipeline jam accident occurs, pull-out type forcing press 2 is connected with backup line 9 by increasing resistance packing ring 5, fastening bolt 7, thus is realized pipeline closed.
Described pipeline control valve 3 top is with rotating valve 31, and inside is the hollow valve roating sphere 32 identical with filling pipeline 4 internal diameter, (see Fig. 3), is realized the rotation of valve roating sphere 32 by rotating valve 31, and then realizes pipeline unlatching and Guan Bi.
By spanner, the pipeline control valve 3 of filling pipeline 4 bottom is closed when pipeline jam accident occurs, the pipeline control valve 3 on backup line 9 top is opened, on the premise of lower pipeline closes, realize the conducting of upper and lower pipeline, prevent forcing press air-flow from reducing pipeline sealing by lower pipeline circulation.
Opening with pull-out type forcing press 2 by described forced forcing press 1 simultaneously, increase pressure reduction in pipeline, solution filling plugging precipitates because of slip, there is bulky grain difficulty conducting accident；After filling pipeline turns on, the pipeline control valve 3 on backup line 9 top is closed, the pipeline control valve 3 of filling pipeline 4 bottom is opened, in making conducting pipeline, slip flows along normal filling circuit, owing to pipeline jam accident result in the precipitation of slip, upper pressure machine can be used to pressurize, ensure being normally carried out of filling operation, thus avoid the waste of filling slurry, save filling cost.Further, since this device is Guan Bi pipeline up and down, improve the security of filling pipeline conducting.
After pipeline turns on, on the premise of the control valve 3 on backup line 9 top is closed, by pull-out type forcing press 2 removal, accident pulp-expelling valve 8 is arranged on backup line 9 end.
Should be understood that; those of ordinary skill in the art is under enlightenment of the present utility model; in the case of without departing from the utility model scope of the claimed protection, it is also possible to making the various deformation such as replacement, simple combination, the scope that is claimed of the present utility model should be as the criterion with claims.
