Bag type dust collector and sectioned bag cage thereof

Abstract

The invention discloses a sectioned bag cage which comprises multiple connected bag cage sections. A clamping groove is formed in one of any two adjacent bag cage sections, and a clamping hook which can extend into the clamping groove to be clamped with the clamping groove so as to achieve connection of the two bag cage sections is arranged on the other of the two adjacent bag cage sections. In the sectioned bag cage, hook-groove structures are adopted replace elastic clamps so as to achieve connection of the bag cage sections, the phenomenon of filter bag puncture caused by drop of the elastic clamps is fundamentally avoided, and normal work of the sectioned bag cage is ensured. In addition, in the mode that the bag cage sections are connected by adopting the hook-groove structures, the accuracy requirement for matching sizes of the connecting positions of the upper and lower bag cage sections is greatly loosened, the manufacturing accuracy of connecting members is also reduced, the clamping grooves and the clamping hooks are both fixed to the bag cage sections, integration of the bag cage sections and the connecting members is achieved, and the connecting stability can be better. Furthermore, free-hand installation can be also achieved without special installing tools, and mounting and dismounting operation are more convenient. The invention further provides a bag type dust collector provided with the sectioned bag cage.

Description

technical field [0001] The invention relates to the technical field of dust removal equipment, in particular to a segmented bag cage. The invention also provides a bag type dust collector with the above segmented bag cage. Background technique [0002] my country's environmental protection department requires 100mg or 50mg / Nm for the early discharge of dust from domestic dust collectors. 3 , so the matching electrostatic precipitator can meet the dust emission index requirements at that time. However, with the new national emission standard of 20mg / Nm 3 The introduction of even stricter standards, especially for coal-fired power plants and steel plants around cities in 11 eastern provinces, even proposed 10-5mg / Nm 3 Due to its high filtration efficiency and low emission, the bag filter technology has been widely used, and has become the mainstream dust removal technology in dust removal industries such as coal-fired power plants, steel plants, and glass kilns.

Problems solved by technology

If the material is too soft, after the elastic clip is buckled into the connection part, the head of the clamped connection part will be easily deformed, resulting in the disappearance of the matching arc of the head, and the elastic clip will easily fall off; if the material is too hard, it will be difficult to form it to pass the punching process. The size of the mold is easy to wear, and the wear of the mold will lead to the size deviation of the elastic clip. The more the number of stampings, the greater the out-of-tolerance rate, which will lead to the deterioration of the connection stability of the elastic clip and the frequent occurrence of the elastic clip falling off. , seriously affecting the normal work of the bag filter

[0005] In addition, due to the small size of the elastic clip and the need for special tools for installation, the installation operation is very cumbersome and inconvenient; generally two people are required to cooperate with the installation, the installation efficiency is low, and the installation quality is not easy to guarantee; due to the number of elastic clips Large and discrete, it is easy to fall between the bag cage and the filter bag during installation. If it is not taken out in time, the filter bag will be punctured during the operation of the bag filter
