Description
Technical field
The utility model belongs to mine production safety equipment, particularly a kind of mining gas discharging malleation tailrace.
Background technology
China's gas serious disaster, gas drainage under suction are the important channels that solves the gas problem, take the extraction measure, and the gas drainage under suction of enrichment in the coal seam is come out, and are to remove gas accident to threaten, ensure safety of coal mines effective measures the most.In gas discharge in mine,, form a large amount of condensed waters in the extraction system pipeline because of each place temperature difference under the coal mine changes greatly; On the other hand, because sandstone crevice water is moisture with this coal seam, hole pumping and mining also can be extracted a large amount of boring water out; No matter be boring water, or condensed water is present in the gas pipeline, all will influence the normal operation of extraction system; When ponding is serious, even cause extraction to be interrupted, cause the gas exceeding limit accident; Therefore, extraction system ponding becomes the major safety risks that influence system stability, and system's work that discharges water is an emphasis always.
Summary of the invention
The purpose of the utility model is to overcome above-mentioned technical deficiency, provides a kind of and discharges water thoroughly the reliable mining gas discharging malleation of sealingly secure tailrace.
The technical scheme that the utility model technical solution problem adopts is: mining gas discharging malleation tailrace comprises cylindrical shell, water inlet, adjutage, the guiding tube that discharges water, bottom support wheel, Draw off valve, chassis, upper and lower standing screw, is characterized on the chassis, being equipped with cylindrical shell, and the top of cylindrical shell is provided with the malleation muffler; The side is provided with water inlet, and the center is provided with Draw off valve on the chassis in cylindrical shell, and center-pole is established in the Draw off valve top; The outer periphery support bar of Draw off valve, support bar top are established governor motion and are limited pallet, limit dress float chassis above the pallet; Load extension bar around above the float chassis; In connecting rod, fixedly load float with following standing screw on the float chassis of center-pole periphery, connecting rod top dress float top cover is used standing screw and is fixedly loaded onto float on the float top cover; Adjutage is established in the center below the chassis; Be provided with tripod in the adjutage, hollow steel ball is housed in the tripod, connect the guiding tube that discharges water below the adjutage.
The beneficial effect of the utility model is: mining gas discharging malleation tailrace can solve the serious problem of fire damp extraction pipeline ponding; The ponding that solves the gas drainage under suction pipeline can improve gas drainage under suction efficient; The cost that saving draws out methane; When drawing out methane, installation discharges water automatically, slag-draining device.When drawing out methane, foreign material such as water, cinder together are drawn out of, and influence the purity of gas and the problem of extraction, and this tailrace can improve the purity of gas, increase economic effect.
Description of drawings
Specify with embodiment below in conjunction with accompanying drawing.
Fig. 1 is a mining gas discharging malleation tailrace structure chart.
Among the figure, 1-malleation muffler; The last float of 2-; The 3-center-pole; The 4-connecting rod; Float under the 5-; 6-limits pallet; The 7-governor motion; The 8-support bar; The 9-chassis; The 10-Draw off valve; The 11-rubber sleeve; 12-bottom support wheel; The 13-guiding tube that discharges water; The 14-adjutage; The 15-hollow steel ball; The 16-tripod; The 17-water inlet; 18-float chassis; Standing screw under the 19-; The last standing screw of 20-; The 21-cylindrical shell; 22-float top cover.
The specific embodiment
Embodiment; With reference to accompanying drawing 1; Fixing four bottom supports wheel 12 in 9 belows, chassis of mining gas discharging malleation tailrace, adjutage 14 is equipped with in the center below bottom 9, and tripod 16 is housed in the adjutage 14; Hollow steel ball 15 is housed in the tripod 16, and adjutage 14 bottoms connect the guiding tube 13 that discharges water.The center connects adjutage 14 and is provided with Draw off valve 10 on bottom 9, in the cylindrical shell 21, Draw off valve peripheral equipment rubber sleeve 11, and the top of Draw off valve 10 connects center-pole 3.Draw off valve 10 is peripherally equipped with support bar 8 on bottom 9; Joint mechanism 7 is debug in support bar 8 tops, dress limits pallet 6 above the governor motion 7; Limit dress float chassis 18 above the pallet 6, on the outer connecting rod 4 is housed above the float chassis 18, dress float top cover 22 on connecting rod 4 tops; On float chassis 18, load float 5, on float top cover 22, use standing screw 20 and load onto float 2 with following standing screw 19.Dress malleation muffler 1 is put into the mouth of a river 17 in the side bottom of cylindrical shell 21 in the center, top of cylindrical shell 21.
The course of work of mining gas discharging malleation tailrace is: when tailrace water inlet 17 continued water, because positive pressure, Draw off valve 10 was closed; Along with the water level rising of cylindrical shell 21, following float 5 produces buoyancy, when water level continues to rise; Last float 2 also touches water, produces buoyancy upwards simultaneously, and Draw off valve 10 was opened automatically when the buoyancy of float 5 and last float 2 generations acquired a certain degree instantly; System begins to discharge water, and things such as body refuse are together emitted, under the effect that limits pallet 6; Upper and lower float 2,5 has lost the buoyancy of water effect; Under the effect of the gravity of malleation and upper and lower float 2,5 and center-pole 3, Draw off valve 10 is closed again automatically, carries out the continuous water of a new round.
