Abstract
The utility model discloses a novel centralized gas extraction box which comprises a box body; a supporting leg is arranged at the bottom of the box body; a water-drainage and air inlet pipe is arranged on one side of the top of the box body; a group of gas extraction air inlet pipes are arranged at the front part of the box body; a branch pipe connector is arranged at the middle position of the top of the box body; a water baffle plate is arranged above the gas extraction air inlet pipes in the box body; and a water-drainage pipe is arranged at the bottom of the box body. Connection with a branch pipe is more convenient and faster; the position of the water-drainage pipe on the side surface of the box body is replaced by a position under the box body, so the water drainage is more thorough; a water level meter is added for clearly observing a water level in the box body and providing a reliable basis for water drainage; a sewage drainage hole is formed so that plugging of the box body is easier to treat; the water baffle plate is added for stopping accumulated water extracted from a drilled hole in the box body by using the gravity of the water and the resistance of the water baffle plate; therefore, water accumulation in a gas extraction main pipeline can be avoided originally.
Description
Technical field
The utility model belongs to the use equipment of gas pumping drill site, concrete a kind of extraction case that relates to gas drill site extraction drill site mash gas extraction and prevent gas pumping pipeline ponding.
Background technology
The concentrated extraction case of gas is the facility to all hole unified connection, unified extractions in the gas drainage under suction drill site.Existing gas concentrates the extraction box structure single, can't directly observe water level inside, and arm connects loaded down with trivial details, and in case phenomenon such as obstruction occurs, treatment process and complexity thereof influence the gas pumping effect to a great extent.
Existing gas concentrates the extraction case to adopt flange to be connected with extraction system arm, and this method of attachment also needs to make in addition the head that gets rid of of a flanged dish, and it is time-consuming not only to operate, and waste material; Gutter is positioned at below, casing side, because factors such as manufacturing process inaccuracy make the horizontal level of gutter be higher than bottom half, causing has a small amount of ponding corrosion casing all the time in the casing, and influences whole extraction effect to a certain extent; At present, gas concentrates the extraction case to judge whether ponding and water accumulating volume are arranged in the casing by method such as playing, listen, and the method is inaccurate, often causes blindness " discharging water ", influences effect; When handling casing and stop up, remove connecting branch, handle from casing top, time-consuming taking a lot of work, and influence gas pumping time of drill site, and also misoperation also may cause the gas exceeding limit accident.Gas is concentrated no any design that blocks water in the extraction case, is drawn out of under the situation of water self gravitation in holing in main conduit extraction negative pressure, and this part water will be drawn into gas pumping trunk pipeline, cause trunk pipeline ponding, influence whole gas pumping effect.
The utility model content
Technical problem to be solved in the utility model provides a kind of convenient and swift and reliable more new-type gas and concentrates the extraction case.
In order to solve the problems of the technologies described above by the following technical solutions: a kind of new-type gas is concentrated the extraction case, comprise casing, the bottom of casing is provided with supporting leg, casing top one side is provided with the air inlet pipe that discharges water, the front portion of casing is provided with one group of gas pumping air inlet pipe, the crown center position of casing is provided with a pipe connector, and the top of the gas pumping air inlet pipe in the casing is provided with watertight shutter, and gutter is arranged on bottom half.
Casing back one side is provided with the fluviograph mounting pipe.
The fluviograph mounting pipe is divided into mounting pipe and following mounting pipe on the same vertical direction, and last mounting pipe is positioned at casing back upside, and following mounting pipe is positioned at the corresponding position of downside, casing back.
Casing back downside is provided with mudhole.
It is more convenient when the utility model is used connecting branch; Gutter is below the casing side changes casing into, and draining is more thorough; Increase fluviograph, can clearly observe water level in the casing, for the work of discharging water provides reliable basis; Increase mudhole, easier processing casing stops up; Increase watertight shutter, utilize the gravity of water self and the resistance of watertight shutter,, stop gas pumping main conduit ponding from root from holing the interior ponding retaining of extracting out in casing.
Description of drawings
Fig. 1 is a front view of the present utility model.
Fig. 2 is the left view of Fig. 1.
Fig. 3 is the vertical view of Fig. 1.
The specific embodiment
Shown in Fig. 1 ~ 3, a kind of new-type gas is concentrated the extraction case, comprise casing 6, the bottom of casing 6 is provided with four supporting legs 5, casing 6 tops one side is provided with the air inlet pipe 2 that discharges water, and the crown center position of casing is provided with a pipe connector 1, and the front portion of casing 6 is provided with one group of gas pumping air inlet pipe 3, the top of the gas pumping air inlet pipe in the casing is provided with watertight shutter 9, and gutter 4 is arranged on casing 6 bottoms.Casing 6 backs one side is provided with fluviograph mounting pipe 8, and a meter mounting pipe in position is divided into mounting pipe and following mounting pipe on the same vertical direction, and last mounting pipe is positioned at casing back upside, and following mounting pipe is positioned at the corresponding position of downside, casing back; Casing back downside is provided with mudhole 7.
Extraction system arm directly is connected with a pipe connector, in economical with materials, improve and operate effect, and can accomplish tightly air tight, raising extraction effect.Bottom half is changed in the position of gutter, can guarantee that the highest level face of gutter is not higher than bottom half, draining is more thorough, and then avoids ponding corrosion casing, improves the application life that gas is concentrated the extraction case, improves the extraction effect to a certain extent.Design water level sight gauge mounting pipe on the casing can be judged water level in the casing behind the installation fluviograph intuitively, accomplishes to shoot the arrow at the target, and improves effect.
At box back surface bottom centre position design mudhole, the casing clogging is handled in the hole thus, only with removing flange, takes away leather packing, and is convenient and swift, and the safety factor height.Above box house gas pumping air inlet pipe, designed watertight shutter, utilized the gravity of water self and the resistance of watertight shutter,, stopped gas pumping main conduit ponding from root from holing the interior ponding retaining of extracting out in casing.
