Description
Technical Field
The invention relates to a metal plate processing technology, in particular to a composite plate surface polishing and grinding dust processing technology.
Background
In the field of processing metal plates at home and abroad, particularly in the production process of explosion welding composite plates, the surfaces of a base material (carbon steel plates such as Q345B, Q235B and the like) and a composite material (titanium plates, stainless steel plates, aluminum plates, copper plates and the like) are required to be polished and derusted, and the surfaces of the composite plates after explosion welding also need to be polished. . When the automatic grinding or polishing equipment is used for processing the surface of the metal plate, a large amount of metal dust is generated to harm the health of staff, and serious pollution is caused to the environment. The dust generated is mainly: metal dust particles generated by plate surface grinding, and impurities such as fine particles of flocks, diamonds, steel grit and the like from which grinding materials (impellers and grinding wheels) fall. Because the grinding material runs at a high speed in the grinding and polishing operation, the generated dust pollution has the following characteristics: the dust is more, the temperature is higher, the instantaneous speed is high, and the dust is dispersed, so that the dust is difficult to seal, cool and collect and absorb. Especially titanium plate, aluminum plate etc. panel surface polishing produces a large amount of sparks, very easily makes titanium powder and other wool floccules burn, causes the phenomenon of catching fire, often burns dust absorption pipeline and dust remover, causes very big inconvenience to dust collection and absorption, produces phenomena such as deflagration even, causes serious harm to personnel, equipment, product. At present, the field of polishing and grinding of metal plates fails to provide an effective dust removal solution. The conventional dust treatment technology and device are as follows: the dust is sealed by adopting a simple grinding wheel cover, the dust is conveyed into the dust remover through a high-temperature-resistant hose and a fan, the dust remover adopts a traditional bag type or dry dust remover, and a high-temperature-resistant filter element is arranged in the dust remover. The following problems exist when the dust remover is used: the dust hood cannot be adjusted when fixed, the sealing effect is poor, and the dust collection capacity is poor; the pipeline is easy to be worn out and burnt out when conveying high-temperature metal dust; the dust remover is easy to be blocked by dust after long-time use, and the dust is difficult to clean; when the combustible metal such as titanium powder is treated, the dust remover is easy to burn and explode, and dust aftertreatment is difficult. The other method is to install the traditional dust remover in a fixed machine room and add a fire extinguishing device, so that dust can be cooled and extinguished in the process of passing through a long-distance air suction channel. Although this approach can reduce the factor of the dust catcher combustion explosion, the dust burning phenomenon cannot be fundamentally eliminated. Based on the problems, the whole process from dust aggregation and absorption to dust treatment adopts the following innovative technical scheme:
(1) The technology and the device of the invention are composed of an automatic polishing equipment main body, a dust collecting and sealing part and a dust extinguishing, absorbing and settling post-treatment part.
(2) Dust collection and sealing part: adopting a flexible and adjustable dust collection technology and a dust collection hood device to seal and collect more than 98% of dust generated in the processing process; the dust conveying device comprises a special dust suction horn mouth, a metal corrugated pipe, a metal straight pipe, a special connecting device and the like, so that smooth high-temperature dust conveying is ensured, and a dust suction pipeline cannot be burnt by sparks;
(3) Dust extinguishment, absorption and precipitation post-treatment part: a special dust and spark extinguishing box and a diversion device are developed, so that dust and spark directly enter the device through the tail end of a fan to finish preliminary dust extinguishing and absorption; the special water bath dedusting water tank is developed, so that dust passing through the fire extinguishing box directly enters the device to finish secondary absorption and treatment of the dust.
By originally invented the key links and the technology, special devices and parts are developed, and the test and the improvement design are continuously carried out, so that the dust removing technology and the device effectively solve the difficult problem of dust treatment in the metal plate processing process, in particular the problems of ignition, explosion and the like of inflammable dust.
