Abstract
The invention relates to an afterheat recycling device of a box type isothermal quenching furnace. The afterheat recycling device comprises a salt tank and a cleaning machine, wherein a heat insulating interlayer is arranged on the side wall of the salt tank; mixing devices and salt flow guide tanks are arranged at the two sides of the salt tank; a guide device is arranged in the heat insulating interlayer of the salt tank, and is connected with a cleaning agent in the cleaning machine through a circulating pump and a circulating pipeline; the cleaning liquid in the cleaning machine is input in the guide device by the circulating pump; the salt tank is cooled; and the heated cleaning agent is returned to the cleaning machine through the circulating pipeline. The afterheat of cooling the salt tank is used as a heat source of the cleaning machine, so that the afterheat recycling device of the box type isothermal quenching furnace has such advantages as energy conservation and high efficiency compared with the prior art.
Description
Technical field
The present invention relates to equipment for Heating Processing technical field, particularly relate to a kind of heat sink of heating chamber of box heat treatment furnace.
Background technology
When the salt bath of box isothermal quenching furnace is normally worked, the temperature of salt bath inside is between 260 DEG C to 400 DEG C, the nitrate formula that isothermal quenching is used is the mixture of 55% saltpetre and 45% Sodium Nitrite normally, the fusing point of mixture: 137 DEG C, so there is thermofin in salt bath outside.When salt bath is in the time processing quenching technology, in order to ensure the performance of workpiece, be nitrate cooling rapidly.Salt bath cooling is at present mainly the case the inside that the nitrate of the face of salt bath is extracted into a specific store by pump, in this chest, lowers the temperature.
Summary of the invention
Object of the present invention is exactly the waste heat recycle device that a kind of energy-conservation, cost-effective box isothermal quenching furnace is provided in order to overcome the defect that above-mentioned prior art exists.
Object of the present invention can be achieved through the following technical solutions: a kind of waste heat recycle device of box isothermal quenching furnace, comprise salt bath and cleaning machine, the sidewall of salt bath is provided with insulating sandwich, it is characterized in that, described salt bath both sides are provided with whipping appts and salt flowage guide path, in the insulating sandwich of salt bath, be provided with guiding device, this guiding device is connected the scavenging solution in cleaning machine with circulation line by recycle pump; Recycle pump is by the scavenging solution input guiding device in cleaning machine, and to salt bath cooling, heated scavenging solution returns in cleaning machine by circulation management.
Described guiding device is the thrust-augmenting nozzle being looped around in salt bath insulating sandwich.
The paddle of described whipping appts is placed in salt flowage guide path, makes the temperature of whole salt bath even.
The workpiece that quenches out from salt bath in production process has adhesion nitrate, the nitrate on workpiece need to be washed down, and the nitrate that the scavenging solution that cleaning workpiece is used obtains after treatment can be put back to again salt bath and continue to utilize.This process of cleaning nitrate completes in cleaning machine the inside, and the scavenging solution that is used for cleaning is exactly that clear water adds clean-out system, carrys out cleaning workpiece and can wash totallyer, because along with the solubleness of the temperature rising nitrate of scavenging solution is larger with the scavenging solution after heating.The normal heating mode of scavenging solution is gas heating or electrically heated.
Compared with prior art, the present invention for energy-conservation, save cost, the lateral septal thermosphere of salt bath has been made totally enclosed, that is to say and between salt bath and the external world, have individual interlayer.In the middle of interlayer, do guiding device, then water flowing carrys out the inwall of cooling salt bath, and the both sides of salt bath are equipped with and are stirred and salt flowage guide path, and the temperature that makes whole salt bath is uniform.Being used for cooling water is the scavenging solution of cleaning machine, can reduce like this temperature of salt bath, can heat up to scavenging solution again.
Brief description of the drawings
Fig. 1 is structural representation of the present invention.
Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is described in detail.
Embodiment 1
As shown in Figure 1, a kind of waste heat recycle device of box isothermal quenching furnace, comprise salt bath 1 and cleaning machine 11, the sidewall of salt bath 1 is provided with insulating sandwich 4, described salt bath 1 both sides are provided with whipping appts and salt flowage guide path 3, the paddle of whipping appts is placed in salt flowage guide path 3, and nitrate 2 flows into salt bath 1 by salt flowage guide path 3, makes the temperature of whole salt bath 1 even.In the insulating sandwich of salt bath, be provided with guiding device, guiding device is the thrust-augmenting nozzle being looped around in salt bath insulating sandwich.This guiding device is connected the scavenging solution in cleaning machine 11 by recycle pump 7 with circulation line; Scavenging solution enters recycle pump 7 from rinse liquid outlet 8, and from recycle pump 7, through cooling fluid as early as possible in 6 guiding devices that enter salt bath, to salt bath cooling, heated scavenging solution returns cleaning machine 11 by scavenging solution import 12 from cooling liquid outlet 13.
Workflow is: utilize pump 7 scavenging solution of cleaning machine 9 to be transported to the interlayer 4 of salt bath, by getting back to cleaning machine the inside from exporting 13 after the guiding device in the middle of interlayer.The workpiece 5 that quenches out from salt bath in production process has adhesion nitrate, the nitrate on workpiece need to be washed down, and the nitrate that the scavenging solution that cleaning workpiece is used obtains after treatment can be put back to again salt bath and continue to utilize.This process of cleaning nitrate completes in cleaning machine the inside, and the scavenging solution that is used for cleaning is exactly that clear water adds clean-out system, carrys out cleaning workpiece and can wash totallyer, because along with the solubleness of the temperature rising nitrate of scavenging solution is larger with the scavenging solution after heating.The normal heating mode of scavenging solution is gas heating or electrically heated.
The object of the invention is: energy-conservation, efficient.Utilize the waste heat of salt bath cooling as the thermal source of cleaning machine.
