Abstract

The application relates to the technical field of bag-type dust removing equipment, in particular to a framework structure of a dust removing bag for environmental protection engineering, which comprises a top frame, a fixed rod, a bottom frame, a movable rod, a temporary assembly part, a lower pressing ring, a locking part, a sealing plate, a supporting rod, an adjusting ring, an adjusting part and an unlocking part. According to the application, the movable rod is matched with the stool assembly part, so that the framework is kept in a contracted state during installation, and the cloth bag is prevented from being scratched. Pressing down the pressing ring after in place can automatically lock and expand the movable rod to support the cloth bag, and simultaneously pushing the sealing plate to press the opening of the cloth bag. During normal operation, the bag negative pressure drives the movable rod to move inwards, and the sealing plate is further pressed by the adjusting part, so that sealing is enhanced. When the air current is unusual is led to the sack breakage, and the air current of increase promotes the closing plate, through unlocking part automatic unlocking, and lower clamping ring spring up resets, and the closing plate seals the centre bore, both prevents unfiltered gas emission, provides audio-visual damaged position indication again for maintainer, promotes maintenance efficiency.

Description

Framework structure of dust removal cloth bag for environmental protection engineering Technical Field The invention relates to the technical field of cloth bag dust removing equipment, in particular to a framework structure of a dust removing cloth bag for environmental protection engineering. Background In the field of environmental engineering, a bag-type dust collector is used as core equipment for industrial flue gas purification, and the dust collection efficiency and the operation stability of the bag-type dust collector are directly related to the pollutant emission control level. The dust removing cloth bag is used as a filtering element, and the structural support is needed to be provided by the internal framework, so that the cloth bag is prevented from collapsing and deforming under the pulse blowing or the air flow impact, and the filtering area and the ash removing effect are ensured. At present, a common dust removing cloth bag framework mostly adopts an integral welding type cage structure and is formed by staggered longitudinal ribs and annular ribs, and the top end of the common dust removing cloth bag framework is provided with a mounting flange for being fixedly connected with a dust remover pattern plate. However, in the installation process of the existing framework structure, the framework is required to be vertically downwards placed into the cloth bag from the holes of the flower plate, the cloth bag is in a natural fold or folding state in an undeployed state, and when the framework is downwards placed, the end parts of longitudinal ribs or the edges of annular ribs of the framework are extremely easy to scrape with the inner wall of the cloth bag, so that the filter material is scratched, worn or even perforated, and the service life and the filtering precision of the cloth bag are influenced. In addition, when the existing cloth bag is locally damaged due to long-term operation, dust-containing air flow can directly enter the air purifying chamber from the damaged position, so that the unit emission concentration exceeds the standard, but because the dust remover generally adopts a multi-unit parallel structure, operators are difficult to quickly position the specific damaged cloth bag, and the maintenance efficiency is low due to the fact that the specific damaged cloth bag is often required to be disassembled and inspected one by one. If the damaged cloth bag is not found in time, the continuous high-concentration discharge not only violates the environmental protection standard, but also accelerates the abrasion of equipment such as a subsequent fan, a pipeline and the like, and causes larger economic loss and environmental protection risk. Therefore, a framework structure of the dust removal cloth bag for environmental protection engineering is provided. Disclosure of Invention The invention aims to provide a framework structure of a dust removing cloth bag for environment-friendly engineering, which aims to solve the problems that in the prior art, a framework is easy to contact and scratch with the inner wall of a wrinkled cloth bag when the framework is put down, so that the cloth bag is easy to scratch, the service life of the cloth bag is influenced, and when the damaged cloth bag is required to be replaced after being damaged, the damaged cloth bag is difficult to accurately position and distinguish, and the cloth bag is required to be inspected one by one, so that the maintenance efficiency is low. In order to achieve the above purpose, the present invention provides the following technical solutions: The utility model provides a skeleton texture of dust removal sack for environmental protection engineering, includes roof-rack, dead lever, chassis, movable lever, civilian dress part, lower clamping ring, locking part, closing plate, butt pole, adjusting ring, adjustment part and unblock part, roof-rack, chassis from the top down connect gradually in the roof-rack lower extreme, the roof-rack center is provided with the centre bore the movable lever passes through the civilian dress part to be connected between roof-rack and chassis, the civilian dress part is used for keeping the movable lever in the inner circle position of roof-rack when installing skeleton structure is whole, the lower clamping ring passes through locking part to be connected in the roof-rack upper end, locking part is used for pressing down the assigned position when the clamping ring to, will press down the clamping ring locking in the roof-rack to cooperate the civilian dress part to make the movable lever remove the outer lane of roof-rack, the closing plate is provided with a plurality of, every the closing plate all is connected through torsional spring and roof-rack lower extreme, a plurality of the centre bore closure of closing plate, the adjusting ring passes through adjustment part sliding connection and presses down the ring, connect in the adjusting ring, the clamping rod, the tip rod,
