Abstract

The utility model discloses a ventilation unit for solve the problem of long distance one-end tunnelling working face local ventilation difficulty. The embodiment of the utility model provides a ventilation unit, including the ventilation hole that link up upper portion tunnel and lower part tunnel, the fan of new trend is introduced in the installation of ventilation hole upper portion, and ventilation hole lower part export is located the ventilation hole chamber to at ventilation hole bottom installation new trend pipe, the new trend pipe exit is located lower part tunnel working face. The device reduces transmission distance and the damage of long distance transmission dryer and the fresh air supply that connection air leakage leads to not enough through introducing upper portion tunnel new trend, guarantees working face fresh air supply safety.

Description

Ventilation device
Technical Field
The utility model relates to a ventilation technology field especially relates to a tunnel working face ventilation unit.
Background
With the development of the mining depth of the mine tunnel and the expansion of the production scale, a long-distance single-head tunneling working face is often generated in the development project, and the ventilation of the tunneling working face is very important for the safety and health of operating personnel.
The single-head tunneling project is generally long in length and has a plurality of turns, only the traditional local fan pumping and exhausting mixing and relay type local ventilation modes are adopted, and due to the fact that the air duct is too long in length and the relay fans are various, the problems of air leakage of a joint, cracking of the joint, breakage of the air duct and the like exist, the air leakage amount is large, and the ventilation safety of the working face cannot be fully guaranteed.
The design of the ventilation device which can meet the requirement of a long-distance single-head tunneling working face is a key problem for ensuring the development of a single-head tunneling project.
Disclosure of Invention
The embodiment of the utility model provides a ventilation unit for the ventilation of long distance one-end tunnelling working face, guarantee that the tunnelling engineering is develoied smoothly.
The embodiment of the utility model provides a ventilation unit, a serial communication port, including the ventilation hole that link up upper portion tunnel and lower part tunnel, the fan of new trend is introduced in the installation of ventilation hole upper portion, and ventilation hole lower part export is located ventilation hole chamber to at ventilation hole bottom installation new trend pipe, new trend pipe exit is located lower part tunnel working face.
In a preferred embodiment, a draw-out fan is installed at the working surface of the lower roadway and is connected with a blow-down air cylinder to discharge dirty air to the return air side of the lower roadway.
In a preferred embodiment, the fan is a centrifugal fan.
In a preferred embodiment, the fresh air source point and the dirty air discharge point are horizontally spaced from each other by a distance that does not cause a circulating air phenomenon.
The utility model discloses beneficial effect includes: the device reduces transmission distance and the damage of long distance transmission dryer and the fresh air supply that connection air leakage leads to not enough through introducing upper portion tunnel new trend, guarantees working face fresh air supply safety.
Drawings
Fig. 1 is a schematic structural diagram of an embodiment of the present invention.
Detailed Description
A specific embodiment of a ventilation device according to an embodiment of the present invention will be described in detail below with reference to fig. 1.
The embodiment of the utility model provides a pair of ventilation unit, including the ventilation hole 6 that link up upper portion tunnel 1 and lower part tunnel 2, the fan 7 of new trend is introduced in the installation of 6 upper portions in ventilation hole, and 6 lower part exports in ventilation hole are located ventilation hole chamber 9 to at 6 bottom installation new trend pipes in ventilation hole 3, 3 exits in new trend pipes are located lower part tunnel working face 5.
Adopt down-the-hole drill drilling diameter 110 millimeters ventilation hole 6 to switch on upper portion tunnel 1, through fan 7, the centrifugal fan that adopts of preferred, the wind pressure is bigger more be applicable to long distance wind path transmission like this, and air supply is to lower part tunnel 2 ventilation hole chamber 9 downwards, and ventilation hole chamber 9 concurrently does and dodges the chamber, at the ventilation hole 6 bottom installation fresh air pipe 3 of the chamber 9 that corresponds the ventilation hole, finally send fresh air into working face 5. In order to better ensure the air freshness, a draw-out fan 8 is arranged near the working face 5, a connecting blow-down air cylinder 4 leads dirty air into the air return side of the lower roadway 2, a distance which does not generate a circulating air phenomenon is formed between a fresh air source point and a dirty air discharge point in the horizontal direction, and the local ventilation of the single-head tunneling working face can be better ensured.
When the tunneling working face moves forward for a certain distance, the ventilation holes 6 are newly arranged to be communicated, and a new ventilation device is arranged, so that the length of the tunneling working face does not influence the feeding of fresh air.
The ventilation device of the embodiment of the utility model reduces the transmission distance and the insufficient fresh air supply caused by the damage of the long-distance transmission wind cylinder and the connection air leakage by introducing the fresh air of the upper laneway, and ensures the safety of the fresh air supply of the working face; meanwhile, a sewage air discharge system which does not generate circulating air is added, so that the freshness of the air of the working face is better ensured.
It will be apparent to those skilled in the art that various changes and modifications may be made in the present invention without departing from the spirit and scope of the invention. Thus, if such modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include such modifications and variations.
