Description
Technical field
The present invention relates to sack cleaner, especially a kind of dedicated points welding machine of sack cleaner cage bone.
Background technology
Fast development along with industry; Industry such as electric power, metallurgy, building materials, chemical industry all can produce amounts of dust every year; Health, atmospheric environment caused have a strong impact on; Especially in the volume of smoke of coal-burning power plant's discharging, contain a large amount of pellets (PM10 and PM2.5), very big to human health damage.
Sack cleaner is as cleaner; Have the cleaning efficiency height, characteristics such as floor space is little, reliable, maintenance cost is low and adaptability is strong, be widely used in numerous industries such as thermal power generation, iron and steel, nonferrous metallurgy, chemical industry, building materials, machinery, electronics.Because the distinctive dust removal mechanism of sack cleaner, the dust layer that the filter bag surface forms can carry out neutralization reaction with acidic gas in flue gas, plays the effect of auxiliary desulfurization, denitrogenation, removal dioxin, thereby can reach better air purification effect.
The dust removing units of existing sack cleaner (shown in Fig. 2 to 5); Mainly comprise filter bag 3 and be arranged at being used in the filter bag 3 and support filter bag 3, prevent the cage bone that filter bag 3 subsides; Said cage bone; Mainly be made up of a plurality of support rings 2 and many perpendicular muscle 1 that are distributed in support ring 2 peripheries, said support ring 2 all adopts stainless steel material with perpendicular muscle 1, adopts welding manner affixed between support ring 2 and the perpendicular muscle 1.Dusty gas 4 gets in the filter bag 3 from filter bag 3 outsides, and dust is blocked in filter bag 3 outer surfaces; When filter bag 3 surperficial laying dusts reach a certain amount of; By setting program the Compressed Gas 5 of cleaning is jetted by the deashing control device in filter bag 3 outside filter bag 3 with the extremely very brief time; Produce rapid expansion and impact shock; Shake off the dust on filter bag 3 outsides, dust directly falls into ash bucket after in air inlet duct, separating through natural subsidence.Existing above-mentioned dust removing units, the major defect of existence is:
Deduster cage bone easy deformation,Because the gas pressure of filter bag in filtration and deashing state is very big, deduster cage bone uses stainless steel, and rigidity and intensity are not good enough; Each solder joint unbalance stress, deflection differed greatly when each support ring and corresponding perpendicular muscle welded in addition; Make filter bag and cage bone under inferior bumps up to ten thousand, the cage influential point of bone deforms, thereby causes eddy flow; Reduce efficiency of dust collection, accelerate filter bag damage.
Summary of the invention
The objective of the invention is to: the dedicated points welding machine that a kind of sack cleaner cage bone is provided; Can each support ring and corresponding perpendicular muscle is simultaneously spot-welded together, each solder joint is stressed evenly during welding, deflection is less, improves cage fracture deformability; Improve efficiency of dust collection, improve life of bag filter.
For realizing above-mentioned purpose, the present invention can take following technical proposals:
The dedicated points welding machine of a kind of sack cleaner cage of the present invention bone; Said cage bone comprises a plurality of support rings that are uniformly distributed with up and down; With many that are distributed in said support ring periphery perpendicular muscle; Said dedicated points welding machine comprises resistance weldering transformer and spot welding control system; Said dedicated points welding machine comprises that also one is used to clamp the anchor clamps of said support ring and perpendicular muscle, and transfer point welding electrode A ' that is driven by pressure cylinder A and the transfer point welding electrode B ' that is driven by pressure cylinder B, and the quantity of said transfer point welding electrode A ' equates with the quantity of perpendicular muscle and is distributed in the periphery of cage bone one to one with perpendicular muscle; The quantity of said transfer point welding electrode B ' equates and the interior week that be distributed in support ring relative one by one with transfer point welding electrode A ' with the quantity of transfer point welding electrode A '; Under said spot welding control system control; Each transfer point welding electrode A ' presses on perpendicular accordingly separately muscle simultaneously, each transfer point welding electrode B ' presses on corresponding position all in the support ring simultaneously, through the discharge between corresponding mobile spot-wedling electrode A ' and the transfer point welding electrode B ' each perpendicular muscle is welded on the support ring simultaneously.
The material of said support ring and perpendicular muscle is the mild steel of phosphorus content Wc≤0.25% and/or carbon equivalent ce≤0.3%.
Compared with prior art the invention has the beneficial effects as follows: owing to adopt technique scheme, said dedicated points welding machine is provided with the anchor clamps that are used to clamp said support ring and perpendicular muscle, and the quantity of said transfer point welding electrode A ' equates with the quantity of perpendicular muscle and is distributed in the periphery of cage bone one to one with perpendicular muscle; The quantity of said transfer point welding electrode B ' equates and the interior week that be distributed in support ring relative one by one with transfer point welding electrode A ' with the quantity of transfer point welding electrode A '; This structure can be simultaneously spot-welded together with each support ring and corresponding perpendicular muscle, spot welding simultaneously; Each solder joint is stressed evenly during welding; The electric welding deflection is little, has improved the welding quality of cage bone, thereby can improve the non-deformability of cage bone when filtration and deashing; The cage bone is difficult for deforming; Thereby can avoid eddy flow, improve efficiency of dust collection, improve life of bag filter.
Further beneficial effect is: because the material of said support ring and perpendicular muscle is the mild steel of phosphorus content Wc≤0.25% and/or carbon equivalent ce≤0.3%, mild steel when welding because of resistivity than the big 8-10 of copper doubly, require the power of above-mentioned dedicated points welding machine less; The plasticity humidity province is wide, is easy to obtain due plastic deformation, does not need very high electrode pressure; The crystallization temperature district is narrow; High-temp plastic is good, and linear expansion coefficient is not high, thereby hot cracking tendency is little; Carbon and micronutrient levels are low; Do not have high molten oxide, generally quenching structure or field trash can not occur, so need not adopt the complicated technology measure during spot welding; Technological parameters such as welding current, electrode pressure and conduction time have bigger adjustable range, and welding quality is good.
