Description
Technical Field
The invention relates to a mounting structure, in particular to a hood silencer mounting ring platform matched with a hood silencer.
Background
Including boiler steam discharge in petroleum, chemical, metallurgical, textile and other industries and other exhaust pipe discharge. Resulting in radiation of fan and equipment noise through the exhaust pipe outlet. Because the exhaust pipe is arranged higher than surrounding buildings, effective barrier separation is avoided, the surrounding environment is influenced by noise in a relatively large range, and a noise sensitive point is greatly influenced. Therefore, the existing method is to arrange a silencer to reduce noise and then enter a chimney for emission. However, if the equipment room does not reserve the position of the silencer, the noise reduction effect is difficult to achieve. The exhaust pipe of an industrial enterprise is a main factor influencing the overproof noise of a factory boundary. The blast cap silencer with the characteristics of small volume, light weight, simple and convenient installation and low manufacturing cost can meet the requirement of eliminating the radiation noise of the air outlet of the exhaust pipe.
However, during the installation process, a problem arises: according to the integrated emission Standard for air pollutants GB16297-1996, the exhaust outlet is required to be located 15m above the ground and 5m above the building within 200m of the periphery. And the installation of the hood silencer is used as high-altitude installation work, a temporarily constructed steel pipe scaffold or a platform must be arranged according to the standard, so that the cost for erecting and disassembling the steel pipe scaffold is far higher than the manufacturing cost of the hood silencer, and the popularization bottleneck of the hood silencer is formed. How to design a matched low-cost blast cap silencer mounting structure which meets the mounting specification becomes a priority.
Disclosure of Invention
In order to overcome the existing hood muffler installation dilemma. The invention provides a blast cap silencer mounting ring table which can meet the requirement of mounting specifications and is not required to be provided with a steel pipe frame structure and a construction steel pipe frame platform. And has the advantages of small volume, light weight, simple and convenient installation, low cost and the like, and can be installed at high speed by using the aerial ladder vehicle.

The lower supporting semicircular ring is beneficial to improving the contact area between the lower supporting semicircular ring and the pipe wall of the exhaust pipe by using the annular steel hoop, and the wind load resistance of the blast cap silencer mounting ring platform is improved.
The triangular bracket is composed of an angle steel cross rod, an angle steel vertical rod and an angle steel inclined rod, wherein the angle steel cross rod is arranged below the limbs of the angle steel vertical rod, the limbs of the angle steel vertical rod are arranged in the back of the angle steel vertical rod and are parallel to the exhaust pipe wall, the limbs of the angle steel inclined rod are arranged outside the back of the angle steel inclined rod, and an angle steel tip on the upper portion of. The limb back rest of the angle steel cross rod is favorable for reducing the air outlet wind resistance of the hood silencer, and the angle steel tip is consistent with the plane of the upper part of the semicircular ring of the rectangular square pipe, so that the mounting ring platform can bear the noise-eliminating hood uniformly.
The triangular brackets are symmetrically arranged in the semicircular mounting ring table, the included angle between the angle steel inclined rod of each triangular bracket and the pipe wall of the exhaust pipe is less than 45 degrees, and a stiffening rib is arranged between the limb back of each angle steel transverse rod and the semicircular ring of the rectangular square pipe. When the included angle between the angle steel inclined rod of the triangular bracket and the pipe wall of the exhaust pipe is less than 45 degrees, the distance between the annular steel hoop of the lower support semicircular ring and the pipe opening is increased, and the force bearing area of the pipe wall is increased.
The damping elastic cushion is arranged on the inner supporting semicircular ring, the lower supporting semicircular ring and the inner wall of the exhaust pipe in the pipe wall direction. The damping elastic cushion can avoid hard connection between the circular mounting ring platform and the pipe wall of the exhaust pipe, so that damage to the pipe wall of the exhaust pipe can be avoided, and the wind load resistance of the hood silencer can be improved.
The inner diameter curvature of the damping elastic cushion at the inner side of the inner support semicircular ring and the lower support semicircular ring is consistent with the curvature of the outer diameter of the exhaust pipe, and a gap is reserved between the two semicircular installation ring platforms. Through a plurality of fastening bolts connection each other, form the complete hood silencer installation ring platform of closely setting on the blast pipe. The outer diameter of the outer support semicircular ring is consistent with the outer diameter of the hood silencer.
The auxiliary mounting frame is made of T-shaped round pipe sectional materials, stiffening ribs are arranged at the joints of the round pipe sectional materials, mounting rings are arranged on the upper portions of the round pipe sectional materials, and the auxiliary mounting frame is connected with the blast cap silencer mounting ring platform through fasteners. The T-shaped structure of the round pipe profile on the limb backrest is arranged on the auxiliary mounting frame, when the semicircular mounting ring platform is placed at the pipe orifice of the exhaust pipe, the T-shaped structure and the friction resistance of the pipe orifice of the exhaust pipe can be balanced and stable, meanwhile, the T-shaped structure and the friction resistance of the pipe orifice of the exhaust pipe are reduced, and the mounting ring platform can be conveniently moved by an installer, so that the working efficiency is improved.
The invention has the beneficial effects that: the requirement of wind load when the silencer of the wind eliminating cap is used can be met; the structure is firm, the installation is simple, convenient and quick, the requirement of installation specification is met, and the installation efficiency is effectively improved.
The invention is further illustrated with reference to the following figures and examples.
