Abstract
Description
Technical Field
[0001] This utility model relates to the field of ventilation device technology, specifically a ventilation device that is easy to install. Background Technology
[0002] Tunnels can be divided into various types of tunnels used for traffic, such as traffic tunnels and mining tunnels. However, during the construction of these tunnels, ventilation is required to ensure air circulation and facilitate smooth construction. Tunnel ventilation devices are generally classified into forced-in type, exhaust type, and mixed type. Among them, the exhaust type extracts dust, harmful gases, and air from the tunnel and filters the air through the filter element in the exhaust ventilation device before expelling it.
[0003] For example, Chinese Patent Publication No. CN219197382U describes a ventilation device for tunnel construction. The device includes a base, a support, and a support rod. An air inlet pipe is mounted on the first support. One end of the air inlet pipe has a bend, and an air outlet pipe is mounted on the bend. A fan, a blower, and a filter element are located inside the air inlet pipe. The blower is located at its output end, and the filter element is located to one side of the blower. One end of the air inlet pipe opposite the bend is used to connect to an external ventilation duct. The top of the first support rod is connected to the air outlet pipe. A motor is mounted on the air inlet pipe, and clamping components are distributed at the air inlet end of the air inlet pipe. The motor and the clamping components are connected via a transmission unit.
[0004] However, in the above solution, it is inconvenient to connect and support the two dust exhaust pipes at the same time during use. Therefore, additional brackets are required to support the dust exhaust pipes, which increases material consumption and is not very convenient. Utility Model Content
[0005] The present invention aims to overcome the defects of the prior art and provide a ventilation device that is easy to install, thereby solving the above-mentioned technical problems.
[0006] To solve the above-mentioned technical problems, this utility model is implemented as follows:
[0007] A ventilation device that is easy to install is characterized by comprising an L-shaped pipe and a dust exhaust pipe. A fan and a filter element are installed inside the L-shaped pipe, with the filter element located to the right of the fan. Limiting rings are fixedly connected to the outer sidewalls of both the L-shaped pipe and the dust exhaust pipe. An upper arc-shaped clamping plate and a lower arc-shaped clamping plate are engaged with the outer sidewalls of both the L-shaped pipe and the dust exhaust pipe. Fixing plates are fixedly connected to the sidewalls of both the upper and lower arc-shaped clamping plates. The two fixing plates on the sidewalls of both the upper and lower arc-shaped clamping plates are fixedly connected by two bolts and two nuts. Two limiting grooves are provided on the sidewalls of both the upper and lower arc-shaped clamping plates, and these grooves respectively engage with the outer sidewalls of the two limiting rings. Rubber pads are provided on the outer sidewalls of both limiting rings. A base is fixedly connected to the bottom of the lower arc-shaped clamping plate, and a slag discharge structure is provided within the base.
[0008] As a further improvement to this technical solution: the slag discharge structure includes a filter screen, which is fixedly connected to the side wall of the upper arc-shaped plate. The filter screen is located between the upper arc-shaped plate and the lower arc-shaped plate, and between the L-shaped pipe and the dust discharge pipe. The side wall of the lower arc-shaped plate is provided with a slag leakage port, and the side wall of the base is provided with an L-shaped slag discharge groove. The L-shaped slag discharge groove is connected to the slag leakage port, and one end of the L-shaped slag discharge groove is inclined.
[0009] As a further improvement to this technical solution: the filter screen is arranged at an angle.
[0010] As a further improvement to this technical solution: rubber gaskets are fixedly connected to the outer ring sidewalls of the L-shaped pipe and the dust discharge pipe, and the outer ring sidewalls of the two rubber gaskets abut against the sidewalls of the upper arc-shaped plate and the lower arc-shaped plate.
[0011] As a further improvement to this technical solution: each of the bolts and nuts is made of stainless steel.
[0012] As a further improvement to this technical solution: the filter element is a dust collector filter cartridge of the brand Liefert.
[0013] The beneficial effects of this utility model are as follows: As can be seen from the above technical solution, this application provides a ventilation device that is easy to install. With the cooperation of components such as filter screen, dust exhaust pipe, base, and fixing plate, this application can connect and fix two dust exhaust pipes while supporting the dust exhaust pipes, without the need for additional brackets to support the dust exhaust pipes. The operation is simple, convenient and quick. Attached Figure Description
