Abstract
The invention relates to waste heat recovery in the forging press piece conveying process, in particular to an inverted-U-shaped plate heat exchanger for forging press piece waste heat recovery. The inverted-U-shaped plate heat exchanger is characterized in that an inverted-U-shaped heat exchanger main body is provided with a hollow and closed heat preserving layer which is matched with the heat exchanger main body in shape, the lower portion of the heat preserving layer is at least provided with one water inlet pipe orifice, and the upper portion of the heat preserving layer is connected with a water outlet pipe orifice through a water outlet collection pipe. The waste heat recovery heat exchanger is arranged on an original production conveying chain so that the waste heat produced at air cooling time of a workpiece can be recovered, and therefore fuel coal amount of a boiler and heat pollution can be reduced, and waste heat recycle is realized. The inverted-U-shaped plate heat exchanger not only saves energy, but also is green and environment-friendly, is low in cost, and has good economic and social benefits.
Description
Technical field
The present invention relates to a kind of waste heat recovery for the press forging course of conveying, relate in particular to a kind of inverted U plate type heat exchanger for the press forging waste heat recovery.Belong to forging waste heat recovery technology field in the industrial production.
Background technology
As everyone knows, some Large-scale Forging casting die manufacturing enterprises have a large amount of waste heats in production process and produce, and these are dissipated in airborne heat, not only have production safety hidden danger, but also bring thermal pollution can for production and environment.For example certain enterprise has a large amount of waste heats to produce in cylindrical body production.Concrete production technology is: when beginning to produce for ease of moulding, the blank of 32kg is placed on carries out high-temperature heating in the intermediate frequency furnace, about 1200 ℃ of heating-up temperatures, be down to approximately about 1000 ℃ through temperature behind the forging forming, the press forging after the moulding through normalizing (air cooling) process room temperature, the oxide skin etc. of removing the surface is treated to closing in and prepares; The punch forming part is heated to about 1200 ℃ through the heating in medium frequency unit again during closing in, and processing and follow-up finishing step finally make workpiece meet the requirements of shape and performance by closing up.In whole living process, there is a large amount of waste heats to produce, particularly at 1000 ℃ of left and right sides temperature sections.Owing to directly heat be discharged in the atmosphere during part air cooling, so not only caused waste also to bring thermal pollution to cause to production unfavorable.Therefore, be badly in need of a kind ofly reasonably utilizing these heats, reduce the potential safety hazard that thermal pollution brings to production, and the impact that environment is caused.
Summary of the invention
The present invention puts forward for the problems referred to above, purpose provides a kind of at original production carrier chain installation heat recovery heat exchanger of the present invention, waste heat in the time of reclaiming the workpiece air cooling, reduce the boiler fired coal amount and reduce thermal pollution to reach, realize the inverted U plate type heat exchanger that is used for the press forging waste heat recovery of waste heat recovery recycling.
The technical scheme of technical solution problem of the present invention is to achieve these goals:
The inverted U plate type heat exchanger that is used for the press forging waste heat recovery, it is that the heat exchanger main body of inverted U is provided with and the adaptive hollow of this heat exchanger body shape and the heat-insulation layer of sealing; The bottom of described heat-insulation layer is provided with a water inlet pipe mouth at least; The top of described heat-insulation layer links to each other with effluent pipe mouth by the water outlet collector.
Described heat exchanger main body is by the inside and outside plate of inverted U, and several support columns that adapting position is provided with between this inside and outside plate consist of.
Described heat exchanger main body lower end is provided with the location lower margin.
The present invention has following advantages and effect:
The present invention is used for the inverted U plate type heat exchanger of the present invention of press forging waste heat recovery owing to having adopted on the blank carrier chain of forging forming design and installation, utilize the inverted U plate type heat exchanger to reclaim the water that heats the heat-exchanger heat-insulating layer of flowing through the radiant heat of press forging, the hot water that recovery obtains is used for back boiler of feeding or worker's bathing, the purpose that realizes reducing the boiler fired coal amount and reduce thermal pollution takes full advantage of industrial exhaust heat.In addition, for increasing structural strength, several support columns of welding between the inside and outside plate of heat exchanger.Water inlet pipe mouth is distributed in inverted U plate type heat exchanger bottom, bulk density difference after utilizing water temperature to raise rises to the top and enters into heat storage water tank through effluent pipe mouth, this design has utilized the healed water volume-variation and the spontaneous rule that makes progress that produces, thereby has improved heat exchange efficiency.The present invention a kind ofly integrates heat recovery heat exchanger energy-conservation, environmental protection, and with low cost, has preferably economic benefit and social benefit.
Description of drawings
With reference to accompanying drawing, concrete structure of the present invention is described in detail as follows:
Fig. 1 is the structural representation of the duty of embodiment of the present invention;
Fig. 2 is that the K of Fig. 1 of the present invention is to structural representation.
Major part among the figure: water inlet pipe mouth 1, heat exchanger main body 2, heat-insulation layer 3, support column 4, water outlet collector 5, location lower margin 6, effluent pipe mouth 7, automatic blanking line 8, transmission chain 9, forging and pressing workpiece 10.
The specific embodiment
Below in conjunction with specific embodiment the present invention is further elaborated, but protection scope of the present invention is not limited by specific embodiment, is as the criterion with claims.In addition, with under the prerequisite of technical solution of the present invention, any change that those of ordinary skills made for the present invention easily realize or change all will fall within the claim scope of the present invention.
Embodiment 1:
Comprise as shown in Figure 1, 2 water inlet pipe mouth 1, heat exchanger main body 2, heat-insulation layer 3, support column 4, water outlet collector 5, location lower margin 6, effluent pipe mouth 7, automatic blanking line 8, transmission chain 9, forging and pressing workpiece 10.The inverted U plate type heat exchanger that is used for the press forging waste heat recovery, the heat exchanger main body 2 of its inverted U are provided with and the adaptive hollow of these heat exchanger main body 2 shapes and the heat-insulation layer 3 of sealing; The bottom of described heat-insulation layer 3 is provided with two water inlet pipe mouths 1; The top of described heat-insulation layer 3 links to each other with effluent pipe mouth 7 by water outlet collector 5.
