The utility model integrates the advantages of a pneumatic sand blasting technique and a high-pressure hydraulic jetting technique, and has the advantages of simple structure, low manufacture and use cost, low work energy consumption, and high work efficiency.
Description
The utility model belongs to metal surface treating device, is specifically related to the descaling machine of outer coatings such as the oxide skin of a kind of corrosion layer that can remove the metal surface effectively, hot-rolled steel and metal coating material layer.
Metallic surface finishing is one of routine work in the industrial production.Traditional cleaning mainly contains technologies such as manual removal, mechanical removal, chemical scavenging, injection removing, and adopting more is to spray to remove technology.It is mostly bulky that equipment is removed in existing injection, cost an arm and a leg, and the energy consumption height, operating efficiency is low.And stir up a cloud of dust when using, condition of work is very abominable.The design people had once developed the water sand mold metallic surface finishing machine that a kind of working media is the water mortar for this reason, had applied for utility model patent and had been awarded patent right (patent No. is ZL97229300.0).Though this technology overcomes the deficiency of existing cleaning technology, but, water in the underflow liquid of its slush pump pumping only works to suspend, carry grit, compressed-air blast cleaning is worked hardly, and when crossing with water under high pressure because of collision balances out a part of impact energy, cause the rust cleaning efficient of this machine not give full play of.Present normally used dry blasting equipment, compressed-air actuated pressure only is 0.5～0.7MPa, be difficult to reach the purpose of not only carrying sand grains but also sand grains being accelerated to desirable initial velocity, therefore its cleaning efficiency is not high, generally can't make the metal surface reach the bright and clean level of Sa3 level, environmental pollution is also bigger during work.This kind equipment is used to repair, during the rust cleaning of shipbuilding industry cleaning, generally can only so just increase the rust cleaning cost greatly with the copper metallurgy slag as abrasive material.The design people is through concentrating on studies, and the advantage of comprehensive above-mentioned patented technology and existing dry blasting technology, equipment has been developed a kind of gas sand mold metallic surface finishing machine.
It is a kind of simple in structure that the purpose of this utility model is to provide, and can make full use of existing dry blasting equipment, and with low cost, the work energy consumption is low, the metallic surface finishing machine that operating efficiency is high.
The utility model is achieved in that it mainly comprises pneumatic sand blasting device and high pressure water jet system two parts, the former is made up of sand jar, gas-powered pipeline and by-pass valve control of being correlated with and abrasive sand shower nozzle etc., and the high-pressure water nozzle of abrasive sand shower nozzle and high pressure water jet system crosses and is connected on the composite spray jet head.
Because the utility model is combined into a compound high-pressure injection cleaning machinery with pneumatic sand blasting device and high pressure water jet system, has improved the operating efficiency of shot blastinog rust cleaning greatly.And manufacturing cost and use cost are all cheaper, pollute for a short time during use, can use under multiple workplace.
Below in conjunction with accompanying drawing and embodiment the utility model is further described, but the utility model is not limited to shown in the accompanying drawing.
Accompanying drawing is overall structure of the present utility model and working state schematic representation.
As shown in the figure, the utility model mainly is made up of pneumatic sand blasting device and high pressure water jet system two parts, the former have the top of sand jar 2 as its core component, sand jar 2 be provided with salable close add sand mouth 1, top is provided with a vent valve 3, the middle part is connected with compressed air source A, connects threeway 5 through valve 9 through valve 7 respectively by three-way pipe 8, threeway 5 two ends in addition links, is connected with blast tube 6 by valve 4 with the sand export of sand jar 2 respectively, and blast tube 6 communicates with composite spray jet head 10.The high-pressure hydraulic pump 12 that motor 11 drives constitutes the main body of high pressure water jet system, and the water inlet water receiving source W of high-pressure hydraulic pump 12, delivery port cross with blast tube 6 through valve 13, high-pressure water pipe 14 and be connected on the composite spray jet head 10.
The surface of being cleared up workpiece 15 during operation is the α angle with the water, the sand jet that spray, is generally 30～60 °.
Valve 3,4,7,9 of the present utility model is a ball valve, also can adopt the valve of other version, can realize the purpose of this utility model equally.Blast tube 6 all adopts flexible, withstand voltage and wear-resisting pipe with high-pressure water pipe 14, as pneumatic hose etc.
High-pressure hydraulic pump of the utility model and sand jar bottom can be installed wheel and be beneficial to complete machine and move and adapt to different operating conditions.
As an embodiment, when the drive motors of high-pressure hydraulic pump of the present utility model adopted 30KW, pump discharge was 1.5～1.8m
3/ h, pressure are 32～50MPa, and the nozzle life-span generally can be above 400 hours.Shower nozzle of the present utility model can be free movable, and high-pressure water pipe can extend to 200～300m, is easy in big operation place or main equipment (as the boats and ships rust cleaning etc.) cleaning is used.
The course of work of the present utility model is as follows:
At first this is installed each valve and place closed condition, adding the sand mouth by the top then is that (adopting flange arrangement or umbrella shape seal structure) hermetically closing adds the sand mouth in dried abrasive sand S (building sand, extra large sand or breeze etc.) the adding sand jar of 0.1～1.0mm with granularity.Open valve 7 and allow the pressure be 0.5～0.7MPa, flow is 1.5～2.5m
3/ minute compressed air enter sand jar 2 through threeway 8.Opening valve 9 allows compressed air by threeway 5, blast tube 6, composite spray jet head 10 ejections.Determine the aperture of valve 4 according to the corrosion layer of being cleared up or the concrete condition of skin of paint this moment, slowly opens valve 4, the sandblast amount is controlled in the scope of 8～16kg/ branch.Start motor 11 simultaneously, make high-pressure hydraulic pump 12 in non-loaded down running, regulate choke valve 13, determine the aperture of valve 13 according to the concrete condition on processed workpiece surface, generally the pressure with water under high pressure is controlled in 30～50MPa scope.Water under high pressure crosses after high-pressure water pipe 14 enters composite spray jet head 10 and forms six bursts of injection waters, converge the back with the gas sand flow and form high speed abrasion water sand jet, rely on the abrasion effect thoroughly to remove corrosion layer, oxide layer, dope layer and the dirt etc. of metal surface clean.
Characteristics of the present utility model:
1, treatment effeciency height, speed are fast, and its effect generally is above-mentioned patented technology---and 2 times of mortar type metal surface treating machine can reach 80～150m2/ h, and processing cost is cheap, the scope of application is extensive.
