Abstract
The utility model discloses a quenching device, which adopts water and air as the high voltage of heat exchange medium and sprays quenching workpieces with high voltage and high speed during the heat treatment process of the ferrous metal. The primary structure is characterized in that a cylindrical quenching tank is connected with a vent tube, a water service pipe, an inducing draught pipe, and a downflow pipe. The utility model has simple structure, low cost compared with the quenching device with the same scale, low consumption, high efficiency, less environment pollution, etc., in the course of the operation, and the utility model can be used for the quenching device in the course of metallothermic processing. The utility model can be especially suitable to large-sized or a large quantity of bulk workpieces such as the packaging quenching device of bearing parts.
Description
The utility model relates to that to adopt water and air be quenched quenching apparatus in the ferrous metal heat treatment process of workpiece of heat exchange medium high pressure, high-speed sprinkling.
What the quenching process in the ferrous metal heat treatment process generally adopted at present is that groove is bathed quenching, most typical is that steel part is concentrated oil bath quenching mode in the groove, its shortcoming is that quenching process produces a large amount of pyrotechnics, especially its pollution level of quenching in the large-scale oil groove is quite serious, and needs a large amount of quenching oil of consumption to make the quenching cost be difficult to reduce significantly.
88101145 " improved method of heat treating ferrous alloys " a kind of application number disclosed in the Chinese patent communique is, its objective is " reduce the cost of austempering process and the device of only finishing the austempering process with a stove is provided ", its measure is that the foundry goods that will place the Ovshinsky heat-transmission to handle in the stove is being cooled to the austempering temperature with the thermal treatment stove under the Ovshinsky temperature under the pressure jet effect that empty G﹠W is formed, its formation is that the processed workpiece in the thermal treatment stove is placed on the interior stationary work-table of stove, and bell is turnover case.In heat treatment process, case sealing during heating, case opens during quenching, case seals again during tempering, weak point be to lack concrete quenching structure be heat exchange medium input/output structure with and the inherent high-temperature quenching process of thermal treatment in the reliable measure that can bear of refractory materials and heating arrangement.
The purpose of this utility model is to overcome and avoids above-mentioned shortcoming and defect part of the prior art and provide that a kind of collection dress that is applicable to large-scale or a large amount of collection workpiece that loose quenches, especially the collection dress of bearing parts quenches, and is the aerosol quenching device of heat-eliminating medium with air and water smoke.
The purpose of this utility model can realize by following structure: aerosol quenching device, main body are quenching tanks 1, and quenching tank 1 is to adopt general steel plate to be welded into cylindric cell body, and is similar substantially to the shape of existing oil bath quenching tank.Special feature of the present utility model is that cylindric quenching tank 1 is connected with high-pressure air vent-pipe 2, tap water water service pipe 3 and waste gas induced exhaust 4 and waste water outfall sewer 5.Vent-pipe 2 and water service pipe 3 are in the inboard of quenching tank 1 from top to bottom and circumferentially some uniformly at intervals injection arms of cylinder.The injection arm 6 of water service pipe is communicated with at the inboard atomizing arm 10 that distributes of quenching tank with roots blower high-pressure air airduct 7.The water fog applicator of arm 10 adopts civilian Tuoli nozzle 8.The injection direction of inboard alternate uniform air spray arm 9 of quenching tank 1 and atomized water spray arm 10 places the tangential eccentric position of quenching tank 1.The middle dividing plate 11 that leaves plup inlet is set on the top of quenching tank 1.Be provided with closing cap 12 at the top of quenching tank 1.Form the air inducing chamber between dividing plate 11 and the closing cap 12, the air-vent that is distributed with the mix waste gas after attracting air and water smoke heat exchange in the inboard of air inducing chamber is communicated with induced exhaust 4.For make the quenching process heat exchange more fully, equal even effective medium circulation smoothnesses, be provided with the airduct 13 that the jet pipe that is distributed that the airduct that distributes with quenching tank 1 medial surface is communicated with makes progress in the bottom of quenching tank 1.On the bottom surface of quenching tank 1, be provided with and shelve the worktable 15 that the quenching workpiece hangs indigo plant 14.Water reservoir bottom surface below worktable 15 is provided with the submersible pump 16 that its output tube is communicated with outfall sewer 5.
Accompanying drawing is the utility model example structure simplified schematic diagram.
The utility model is described in further detail for illustrated embodiment in conjunction with the accompanying drawings: the accompanying drawing illustrated embodiment is the large-scale aerosol quenching device that quenches after the carburizing of bearing ring collection dress.1 one-tenth cylinder bodily form of its quenching cell body adopts the general steel plate welding, and physical dimension is φ 3000 * 4000mm
2, basic identical with the size shape of original oil bath quenching tank.Be furnished with ventilation, atomizing, induced pipe around in the groove.Middle worktable for the part of knocking off.Suitable for reading have a lid, with the quenching workpiece up and down and automatic shutter.Ventilate with high-pressure air, reach pipeline all around up and down and become tangential inside injection through being evenly arranged in cell wall.The atomizing of water is to supply with high-pressure air with roots blower.Adopt " civilian Tuoli " nozzle.The atomizing pipeline is uniform all around up and down along cell wall with the alternate layout of vent line equally.Atomizing divides upper, middle and lower three districts to supply water.Respectively by three spinner-type flowmeter 17 manual setting confluents.Induced pipe is installed in the place suitable for reading of trough, and high-pressure air and water smoke are introduced pipeline by the air inducing chamber that is arranged in trough top and discharged outdoorly again after gas-water separation after the heat exchange of finishing with the quenching workpiece, and the ponding of trough bottom enters down well by submersible pump.
The utility model has following advantage compared to existing technology:
1. the oil bath of prior art is only quenched, and Wafagndian Bearing Factory is annual to need to consume nearly 30 tons of quenching oil, and produces a large amount of oil smoke when quenching, serious environment pollution, and the utility model to adopt air, water be the low pollution-free a large amount of quenching oils of saving of heat exchange medium cost.
2. the attached facility that helps of prior art oil bath quenching has huge buried storage, plate-type heat exchanger, circulation water tower and oil pump, pump chamber etc., and the aerosol quenching device of the present utility model underground installation that need not simple in structure.Year consumption costs only is 9.6% of oil bath quenching.
3. the cooling performance of oil bath quenching is changeless, and the aerosol quenching device can be by adjusting the atomization quantity of water, and its speed of cooling can be adjusted within a large range.Different steel grades and difform quenching part there is very big adaptability.
