Abstract
The utility model relates to a gas extraction pipe. The gas extraction pipe is arranged between two pipe joints and used for connecting the pipe joints. The gas extraction pipe comprises circular steel plates and cold-drawn wires fixed on the steel plates, the cold-drawn wires are disposed uniformly along the peripheral direction of the steel plates, at least one steel plate is arranged at each of two end portions of the cold-drawn wires, the steel plates and the cold-drawn wires are welded to form a skeleton body, the outer wall of the skeleton body is coated with a galvanized meshed plate, and two ends of the skeleton body coated with the galvanized meshed plate are fixed with the pipe joints respectively. The gas extraction pipe has the advantages that the whole gas extraction pipe is lightweight and convenient to carry; installation is facilitated, and working efficiency is improved; the galvanized meshed plate has more holes in uniform distribution, so that the gas extraction pipe is good in breathability, less prone to blockage and good in extraction effect.
Description
Technical field
The utility model relates to a kind of gas exhaust pipe.
Background technology
At present, the gas pumping in colliery is mainly by use core barrel or PVC sleeve pipe carries out pump drainage, and on core barrel or the tube wall of PVC sleeve pipe, pump drainage is carried out in boring, and the pump drainage effect of this pump drainage mode is bad, and has poor, the susceptible to plugging defect of gas permeability.
Utility model content
The purpose of this utility model is to provide a kind of gas exhaust pipe, and this exhaust pipe pump drainage is effective, the good and difficult obstruction of gas permeability.
For achieving the above object, the utility model has adopted following technical scheme: described gas exhaust pipe is arranged between two unions and for connecting two unions, gas exhaust pipe comprises circular steel plate and is fixed on the hand-drawn wire on steel plate, described hand-drawn wire is circumferentially evenly arranged along steel plate, and described steel plate at least arranges respectively one in two ends of hand-drawn wire, described steel plate and hand-drawn wire welding form skeleton body, the outer wall of described skeleton body is enclosed with zinc-plated mesh plate, the two ends of the described skeleton body that is enclosed with zinc-plated mesh plate are fixed with union respectively.
Hand-drawn wire of the present utility model is circumferentially evenly arranged 6 along steel plate.
Steel plate of the present utility model arranges seven along the length direction of hand-drawn wire, and two two ends that are separately positioned on hand-drawn wire wherein, between two ends that remaining five are evenly arranged in hand-drawn wire.
Insert respectively in the endoporus of two unions at the two ends that are enclosed with the skeleton body of zinc-plated mesh plate of the present utility model, and be welded and fixed with union respectively.
The beneficial effects of the utility model are: 1) whole gas exhaust pipe is lightweight, convenient in carrying; 2) easy for installation, improved operating efficiency; 3) hole of zinc-plated mesh plate is many and be evenly distributed, and good permeability, is difficult for stopping up, and extracting result is good.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described further:
A kind of gas exhaust pipe as shown in Figure 1, gas exhaust pipe is arranged between two unions 1 and for connecting two unions 1, gas exhaust pipe comprises circular steel plate 2 and is fixed on the hand-drawn wire 3 on steel plate 2, hand-drawn wire 3 is circumferentially evenly arranged along steel plate 2, and steel plate 2 at least arranges respectively one in two ends of hand-drawn wire 3, steel plate 2 and hand-drawn wire 3 welding form skeleton body, the outer wall of skeleton body is enclosed with zinc-plated mesh plate 4, and the two ends that are enclosed with the skeleton body of zinc-plated mesh plate 4 are fixed with union 1 respectively.
Further, hand-drawn wire 3 is circumferentially evenly arranged 6 along steel plate 2, is exactly that steel plate 2 is provided with 6 holes of matching with hand-drawn wire 3 specifically, and hand-drawn wire 3 inserts in the hole, and is welded and fixed mutually with hole.
Further, steel plate 2 arranges seven along the length direction of hand-drawn wire 3, and two two ends that are separately positioned on hand-drawn wire 3 wherein, between two ends that remaining five are evenly arranged in hand-drawn wire 3.
Further, insert respectively in the endoporus of two unions 1 at the two ends that are enclosed with the skeleton body of zinc-plated mesh plate 4, and be welded and fixed with union 1 respectively.
Above-described embodiment is described preferred embodiment of the present utility model; not scope of the present utility model is limited; do not departing under the prerequisite of the utility model design spirit; various distortion and improvement that those of ordinary skills make the technical solution of the utility model, all should fall in the definite protection domain of the utility model claims.
