In recent years, with the improvement of national environmental emission standards, the performance index requirements of dust collectors are higher and higher. The flower plate divides the interior of the dust remover into two parts, the upper part is a clean air chamber, the lower part is a filter chamber, a plurality of flower plate holes are arranged on the flower plate and are used for hanging filter bags and bag cages, dust-containing gas enters the filter chamber and is filtered through the filter bags, dust particles are adsorbed on the filter bags, and purified gas enters the clean air chamber and is discharged from an air outlet. The flatness of the pattern plate is a key factor for determining the performance quality of the dust collector and the service life of the filter bag, and because the pattern plate is subjected to the gravity action of the filter bag, the bag cage and adsorbed dust particles, the pattern plate is easy to flex and deform, so that the flatness deviation of the pattern plate is increased, the verticality of the filter bag and the sealing effect at the bag mouth are influenced, and especially under the condition of smaller filter bag spacing, even if the upper part of the filter bag is slightly deflected, the bottom of the filter bag is likely to collide and rub mutually, thereby leading to the damage of the filter bag and exceeding the discharge standard. Therefore, it is important to reinforce the pattern plate in the dust remover and ensure the flatness of the pattern plate.
For the reinforcing of the pattern plate, the method generally adopted at present is to arrange reinforcing ribs on the pattern plate, as shown in fig. 1, and a plurality of flat steel reinforcing ribs 3 are respectively arranged on the pattern plate 2 along the transverse direction and the longitudinal direction, but the structure is more suitable for the situation that the pattern plate holes 201 are arranged in a matrix, and in practical application, the pattern plate holes 201 are also arranged in a quincuncial shape besides the matrix, as shown in fig. 2. When the pattern plate holes are arranged in a quincuncial shape, especially when the space between the pattern plate holes is smaller, flat steel reinforcement is difficult to carry out on the pattern plate. At present, individual dust remover factories consider to reinforce circular ring flat steel or S-shaped flat steel at the periphery of the pattern plate holes, the flat steel cannot be welded and is abandoned because of smaller space between the pattern plate holes, even though the flat steel is welded barely, the pattern plate is easy to deform due to expansion caused by heat and contraction caused by cold in the welding process, meanwhile, the requirement on the processing precision of the circular ring flat steel or the S-shaped flat steel is higher, the difficulty is increased for processing the pattern plate, and meanwhile, the cost of the dust remover is increased.
