Abstract
The utility model relates to a novel water-coal discharger of gas forepumping pipeline which is provided with a tank body (9); the upper part of the tank body is provided with an intake tube (1) and a freeing pipe (2); the bottom part of the tank body is provided with a water-coal outlet (6) provided with a valve (4); and a baffle (3) is hung on the top part of the tank body (9). The novel water-coal discharger of gas forepumping pipeline is characterized in that a filter screen (8) is arranged in the freeing pipe (2). The novel water-coal discharger of gas forepumping pipeline has the advantages that the size of the water discharge is smaller, which lightens the self weight and overcomes the difficulties during the carrying process; the filter screen is additionally arranged at the pumping end, which can effectively prevent crushed coals from being pumped into a drawing-out pipeline; the coal outlet is changed from the original plane into a hopper shape, which is more beneficial to discharging impurities like coals, water, etc; the additionally arranged water discharge installation realizes to discharge the water-coals in the pipelines under normal drawing-out situations; and the baffle is partially welded to reduce the extra drawing-out subpressure.
Description
One, technical field
The utility model relates to the device in the gas roughing pipe in the progress of coal mining, i.e. the gas discharge in mine pipeline equipment that discharges water.
Two, background technology
Along with the increase of the coal mining degree of depth, gas has become a key factor of restriction Safety of Coal Mine Production in recent years.It is one of important means of administering gas that gas is taken out in advance.Yet the ponding (coal) that the extraction that exists in the gas roughing pipe produces affects the normal extraction of gas always.Owing to negative pressure when drawing out methane increases, loine pressure also increases thereupon again, and the integrity of extraction system in serious threat.The tradition of using in the extraction pipeline equipment that discharges water, though make simply, volume is big, influences the normal extraction of gas when discharging water (coal), and (coal) effect that discharges water is bad.
Three, utility model technology contents
The purpose of this utility model is to overcome extraction pipeline many technological deficiencies that interior extraction ponding-coal equipment exists that existing gas is taken out in advance, and novel the discharging water of a kind of gas roughing pipe-coal device is provided.
For realizing its above purpose, fundamentally address these problems, in conjunction with gas drainage under suction and atm difference mechanism, and the negative pressure line theory that discharges water analyzed, on the basis of transforming original tailrace, designed and produced novel discharging water-coal device.The technical scheme of the utility model foundation is: discharge water-the coal utensil have tank body, tank body top drive into tracheae and escape pipe, bottom open the water outlet-coal mouth of band valve, at baffle plate of top suspension of tank body, it is characterized in that in escape pipe, being provided with filter screen.
Further structure is that the tank body bottom is cone and is connected with water outlet-coal mouth.
Further structure is that water-coal export is prolonged again, becomes the short tube shape, and pipe top and bottom are provided with two valves.
Further structure is that the baffle plate that will be arranged in the tank body is divided into some, and a certain limit of each piece is connected with the top board or the side panel of tank body.
Superior part of the present utility model is that the tailrace volume reduces, and has alleviated own wt, has overcome the difficulty in the handling process; The end of bleeding adds filter screen, can prevent effectively that broken coal from being entered extraction pipeline; Coal discharge outlet changes funnel-form into by original plane, more helps the discharging of foreign material such as coal, water; The additional facility that discharges water has been realized the interior water-coal of discharge line under the normal extraction situation; Baffle plate adopts local welding, reduces extra extraction negative pressure.
Four, description of drawings
Fig. 1 and 2 is the structural representation of tailrace of the present utility model.
Fig. 3 and 4 is that tailrace shows the structure intention before the utility model transformation.
Five, the specific embodiment
The utility model gas roughing pipe discharges water-the coal device, sees also accompanying drawing 1 or 2.It has tank body 9, tank body 9 tops are driven tracheae 1 and escape pipe 2 into, and the bottom has the water-coal export 6 of band valve 4, and the baffle plate 3 of top suspension at tank body 9 is characterized in that being provided with filter screen 8 in escape pipe 2.During use, discharge water when the mist that contains water-coal enters into-tank body 9 of coal device in, through behind the baffle plate 3, hinder and change the flow velocity and the flow direction of gas, under action of gravity, force most water-coal particulate separated from the gas, water-coal particulate falls into tank base.Water in mist-coal fraction of particle more for a long time, some water that is not separated-coal particulates when entering into escape pipe 2, can be stopped by set filter screen 8 in escape pipe once more, prevent that it from sucking extraction pipeline.
Further structure is that tank body 9 bottoms are cone 5 shapes and are connected with water-coal export 6.The structure of former tank body is referring to accompanying drawing 3 or 4.Its underpart is the plane, and the water that falls-coal particulate has some bottoms that are trapped in tank body, thereby influences the extraction of methane gas.After redesign, the tank body bottom is cone shape 5 or funnel structure, and the water that more helps falling-coal particulate enters into water-coal export 6.
Further structure is that water-coal export 6 is prolonged again, becomes short tube, and pipe top and bottom are provided with valve 4, valve 7.When normally drawing out methane gas, keep valve 4 often to open, valve 7 is normally closed.Discharge water-during the coal particulate, valve-off 4 is opened valve 7, and water-coal dirt is emitted the extraction that can't have influence on gas smoothly, reaches blowdown and carries out simultaneously with drawing out methane.
Further the baffle plates 3 that are arranged in the tank body 9 of structure are divided into some, and a certain limit of each piece is connected with the top board or the side panel of tank body 9.Baffle plate in former discharging water-coal device jar is a whole plate, can't solve negative pressure increase when drawing out methane, the problem that loine pressure also increases thereupon.Baffle plate 3 of the present utility model is divided into several, and adopts local welding, has reduced extra extraction negative pressure.
