Description
Technical Field
The utility model belongs to the technical field of colliery is headwork face ventilation equipment in the pit, specifically speaking relates to a colliery is controllable wind formula wall dryer in the pit.
Background
A large amount of dust is generated in the production process of the underground coal mine tunneling working face, and how to control the dust diffusion makes the dust control effect more obvious, reduces the dust concentration of the working place, creates a good working environment for workers at the same time, and is a long-term exploration subject of a mine.
At present, wall-through wind cylinders are mostly adopted for ventilating a tunneling working face. When local ventilation is carried out, if the air duct penetrates through the air door wall (or the wind-break wall), a hard air duct needs to be installed, the hard air duct is installed in the air door wall (or the wind-break wall), and two ends of the hard air duct are connected with the soft air duct. Meanwhile, the hard air duct is a cylindrical iron air duct welded by iron sheets, is light in weight and low in strength, needs to be dismantled after use, needs to plug a passing air door wall (or a wind shielding wall), and is large in workload and poor in wall aberration. In addition, current wall dryer does not possess the amount of wind regulation and control function.
SUMMERY OF THE UTILITY MODEL
In order to solve the above problems, a controllable air type wall-through air duct for a coal mine is proposed.
In order to achieve the above object, the utility model provides a following technical scheme:
a colliery is controllable wind formula wall dryer in pit includes:
the adjusting window comprises a window frame and a multi-stage adjusting blade, the end part of the adjusting blade is connected with a connecting rod penetrating through the window frame, the connecting rod is rotatably connected with the window frame, and the tail end of the connecting rod is provided with a locking bolt;
the transition section, it is equipped with 2, and 2 transition sections are located the different ends of barrel respectively.
Further, the window frame is welded with the barrel.
Further, the cylinder is made of metal iron.
Further, the multi-stage adjustment blade is disposed along a height direction of the window frame.
Further, the bottom of the adjusting blade is provided with a liner.
Further, the transition section is provided with a cone shape.
Further, the cylinder is rectangular.
Further, the adjusting blade is made of metal.
The utility model has the advantages that:
the ventilation quantity is adjusted by means of the adjusting blades and the connecting rods, the structure is simple, the operation is convenient, the plugging does not need to be removed after the device is used, manpower and material resources are saved, the reliability of local ventilation is improved, and the labor intensity of underground operation is reduced.

fig. 2 is a side view of the overall structure of the present invention.
In the drawings: 1-cylinder, 2-window frame, 3-adjusting blade, 4-connecting rod, 5-locking bolt, 6-gasket and 7-transition section.
Detailed Description
In order to make those skilled in the art better understand the technical solution of the present invention, the following description, together with the drawings of the present invention, clearly and completely describes the technical solution of the present invention, and based on the embodiments in the present application, other similar embodiments obtained by those skilled in the art without creative efforts shall all belong to the protection scope of the present application. In addition, directional terms such as "upper", "lower", "left", "right", etc. in the following embodiments are directions with reference to the drawings only, and thus, the directional terms are used for illustrating the present invention and not for limiting the present invention.
The present invention will be further described with reference to the accompanying drawings and preferred embodiments.
The first embodiment is as follows:
as shown in fig. 1 to 2, the underground coal mine controllable air type wall-through air duct comprises a tube body 1 and a transition section 7, wherein the tube body 1 is made of metal iron and penetrates through an air door wall (or a wind-shield wall). The transition section 7 is provided with 2, and 2 transition sections 7 are located the different ends of barrel 1 respectively, and transition section 7 is direct to be connected with soft guide duct.
In order to adjust the ventilation quantity conveniently, the barrel 1 is internally provided with an adjusting window. The adjusting window includes window frame 2 and multistage adjusting vane 3, window frame 2 and barrel 1 welding to reinforcing stability, multistage adjusting vane 3 sets up along the direction of height of window frame 2. The end connection of adjusting blade 3 has a connecting rod 4 that runs through window frame 2, and connecting rod 4 and window frame 2 rotatable coupling, and adjusting blade 3 and connecting rod 4 fixed connection are in order integratively integrative, rotate connecting rod 4 and drive adjusting blade 3 and rotate in step to adjust the air volume. The tail end of the connecting rod 4 is provided with a locking bolt 5, the locking bolt 5 is screwed to fix the connecting rod 4, the adjusting blade 3 is prevented from automatically overturning, the aim of stabilizing the wind flow is achieved, the locking bolt 5 is loosened, and the connecting rod 4 can be rotated to adjust the ventilation quantity.
The bottom of the adjusting blade 3 is provided with a gasket 6 to reduce the friction between the adjusting blade 3 of the adjacent stage and the window frame 2 of the adjusting blade 3. Meanwhile, the transition section 7 is conical, and the barrel 1 is rectangular, so that the barrel can be better contacted with a wall body, air leakage is reduced, and the installation stability is improved. The adjusting blades 3 are made of metal, so that the problems of corrosion, damage caused by blast wave in blasting operation and the like are avoided, and the ventilation reliability is improved.
In this embodiment, the diameter of the outer opening of the transition joint 7 is 670mm, the diameter of the inner opening of the transition joint 7 (i.e. the connecting end between the transition joint 7 and the cylinder 1) is 560mm, the diameter of the soft air duct is 700mm, the size of the cylinder 1 is 570mm × 570mm × 450mm, and the length of the cylinder 1 is 750 mm.
The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the scope of the invention, i.e. the present invention is intended to cover all equivalent variations and modifications within the scope of the present invention.
