Abstract
The invention relates to a quenching tank cooling spray system for heat treatment of metal workpieces, comprising a cooling tower and a quenching tank, wherein the quenching tank is connected with the cooling tower through a liquid inlet pipe and a liquid return pipe and internally provided with a stirrer; the bottom of the quenching tank is provided with a spray pipe with spray holes; the spray pipe is connected with the liquid inlet pipe, and the liquid return pipe is connected with the upper part of the quenching tank and provided with a circulation pump. In the invention, the spray pipe is arranged at the bottom of the quenching tank, a quenching medium is upwards sprayed out of the spray pipe at the bottom of the quenching tank and flows back to the cooling tower through the liquid return pipe arranged at the upper part of the quenching tank under the action of the circulation pump, thereby improving the circulation speed of the quenching medium in the quenching tank; and the stirrer is arranged in the quenching tank so that the quenching medium uniformly turns over. The invention can ensure that workpieces are uniformly and rapidly cooled in the quenching tank.
Description
(1) technical field
The present invention relates to a kind of metal heat treatmet equipment, be specially a kind of quenching tank cooling spray system.
(2) background technology
Quenching is metal works is heated to a certain proper temperature and keeps for some time, immerses in the quenching media refrigerative metal heat treatmet technology fast immediately.Quenching media commonly used has hardening liquid, salt solution, water, mineral oil, air etc.The purpose of quenching is to make supercooled austenite carry out martensite or bainite transformation, obtains martensite or bainite structure.Quenching cooperates with the tempering of differing temps, can increase substantially intensity, toughness and the fatigue strength of metal, and can obtain cooperation (comprehensive mechanical performance) between these performances to satisfy different service requirementss.In addition, the steel also can make some properties that quenches obtains the certain physics chemical performance, as quenching make Permanent Magnet Steel strengthen its ferromegnetism, stainless steel improves its solidity to corrosion etc.
But existing quenching technology influences because of being subjected to equipment, medium, Working environment, auxiliary means, operating skill etc., and technology is difficult to stable, and wherein the hydrologic cycle cooling system in the quenching tank is an one of the main reasons.The hydrologic cycle cooling system of existing quenching tank, a kind of is to be linked to each other with quenching tank by pipeline by cooling tower, and another kind is to arrange agitator in quenching tank, and its shortcoming is that poor cooling performance and inhomogeneous cooling are even.
(3) summary of the invention
At the problems referred to above, the invention provides a kind of quenching tank cooling spray system, its cooling performance is good and cooling is even.
Technical scheme of the present invention is such: it comprises cooling tower and quenching tank, quenching tank links to each other with cooling tower by liquid-inlet pipe and liquid returning tube, it is characterized in that: be provided with agitator in the described quenching tank, the bottom of described quenching tank is provided with the shower that has spray apertures, described shower links to each other with described liquid-inlet pipe, described liquid returning tube links to each other with the top of described quenching tank, and described liquid returning tube is provided with recycle pump.
The further technical scheme of the present invention is: described shower has a plurality of, links to each other with described liquid-inlet pipe by the feed liquor arm respectively; Be respectively arranged with the tensimeter valve on described liquid-inlet pipe, feed liquor arm and the liquid returning tube; Described quenching tank is the rectangular parallelepiped groove, and described agitator has two, arranges in described quenching tank interior opposite angle; Also be provided with strainer on the described liquid returning tube.
The present invention is provided with shower in the bottom of quenching tank, and quenching media flows back to cooling tower by the liquid returning tube that is arranged on quenching tank top from the upwards ejection of shower of quenching tank bottom under the effect of recycle pump, improved the speed of circulation of quenching media in the quenching tank; In quenching tank, be provided with agitator, quenching media is seethed evenly.The present invention can make workpiece obtain in quenching tank evenly, cool off fast.
(4) description of drawings
Fig. 1 is a structural representation of the present invention.
(5) embodiment
As shown in Figure 1, the present invention is a kind of heat treated quenching tank cooling spray system of metal works that is used for, and it comprises cooling tower 1 and quenching tank 7, and quenching tank 7 links to each other with cooling tower 1 by liquid-inlet pipe 4 and liquid returning tube 2.Improvements of the present invention are: be provided with agitator 5 in quenching tank 7, be provided with the shower 8 that has spray apertures 9 in the bottom of quenching tank 7, shower 8 links to each other with liquid-inlet pipe 4, and liquid returning tube 2 links to each other with the top of quenching tank 7, and liquid returning tube 2 is provided with recycle pump 10.After the present invention improved like this, quenching media flowed back to cooling tower 1 by the liquid returning tube 2 that is arranged on quenching tank 7 tops from the upwards ejection of shower 8 of quenching tank 7 bottoms under the suction function of recycle pump 10, improved the speed of circulation of quenching media in the quenching tank 7; In quenching tank 7, be provided with agitator 5, quenching media is seethed evenly.
Shower 8 can have a plurality of, is three shown in Fig. 1, and it links to each other with liquid-inlet pipe 4 by feed liquor arm 6 respectively.
Pressure for switch pipeline loop and indication pipeline medium is respectively arranged with tensimeter valve 3 on liquid-inlet pipe 4, feed liquor arm 6 and liquid returning tube 2.
Quenching tank 7 in the present embodiment is the rectangular parallelepiped groove, and agitator 5 is provided with two, arranges in quenching tank 7 interior opposite angles, can make the quenching media of quenching tank 7 stir more evenly like this.
On liquid returning tube 2, also be provided with strainer 11, be used to filter the quenching media of backflow, make it cleaning.
Working process of the present invention is: under the suction function of recycle pump 10, quenching media from the first half of quenching tank 7 through recycle pump 10-strainer 11-cooling tower 1 cooling-quenching tank 7 bottoms-jet flow (stirring), circulation and so forth.Quenching media in the quenching tank 7 cools off fast by the recycle system and sprinkling system, and homogeneity and speed of cooling all are significantly improved.
