Description

TECHNICAL FIELD

[0001] The utility model relates to dust removal equipment technical field, concretely is a filter core cross type pressing plate structure. BACKGROUND

[0002] The dust remover using ceramic filter core is a kind of equipment specially designed for high temperature and corrosive gas purification in industrial environment. It utilizes the excellent heat resistance and chemical stability of ceramic material, and the gas containing particulate matter is physically intercepted by porous ceramic filter core, so that particulate matter adheres to the outer surface of filter core, and clean gas is discharged through filter core micropore. Ceramic filter core not only can effectively remove small particles, but also has high mechanical strength, and can maintain long service life under harsh working conditions. This dust remover is widely used in flue gas treatment system in metallurgy, cement production, electric power and other industries to meet strict environmental emission standards.

[0003] In the prior art, the filter cores of the dust remover are mainly fixed and installed on the steel plate by a large pressing plate through bolts. This installation mode of filter core makes it necessary to disassemble a whole pressing plate when replacing a certain group of filter cores in the dust remover, which is inconvenient for maintenance of the equipment. Moreover, the traditional bolt installation mode is prone to loosening after long-time operation of the dust remover, which causes the filter cores to shake and collide with each other, resulting in damage. Therefore, we propose a filter core cross type pressing plate structure. SUMMARY

[0004] In view of the deficiencies of the prior art, the utility model provides a filter core cross type pressing plate structure, which is installed on the top of the steel plate and is used for fixing a plurality of filter cores. The fixing assembly is provided with a plurality of pressing plates, and each group of pressing plates is arranged at the diagonal intersection of the plurality of filter cores. The pressing points of the pressing plates are respectively pressed on different filter cores, so that each group of filter cores is subjected to the force of four pressing points. This cross type pressing plate structure enables each group of filter cores to be replaced individually. The pressing plate structure is simple, has low material waste rate, and is convenient, time-saving and labor-saving to manufacture. A first wedge washer and a second wedge washer are arranged between the nut and the pressing plate. The first wedge washer and the second wedge washer are each provided with a plurality of large wedge teeth on the side close to each other. The first wedge washer and the second wedge washer are each provided with a plurality of small wedge teeth on the side away from each other. When the nut is tightened, the bottom surface of the nut and the top surface of the first wedge washer are in abutment under the pressing force of the nut, and the bottom surface of the second wedge washer and the top surface of the pressing plate are in abutment. The small wedge teeth are engaged to avoid sliding. The large wedge teeth between the first wedge washer and the second wedge washer are engaged. Since the rise angle at the engagement position is greater than the thread rise angle of the screw rod, the lift generated by the engagement of the first wedge washer and the second wedge washer is greater than the lift generated by the loosening of the nut. Therefore, the nut is tightened to avoid loosening, which avoids the shaking of the filter cores and solves the problem.
