Description
Technical field
The utility model belongs to technical field of heat treatment equipment, relates in particular to a kind of two cooling heat treatment quenching tank.
Background technology
Quenching is the one of intermetallic composite coating thermal treatment process, and quenching metal works is heated to a certain proper temperature and keeps for some time, and immerse in quenching media immediately and cool fast, conventional quenching media has salt solution, water, mineral oil, air etc.
Coordinated with the tempering of differing temps by quenching, the intensity of metal, toughness and fatigue strength can be increased substantially, and the Different matching (comprehensive mechanical performance) that can obtain between these performances is to meet different service requirementss.Quench in addition and the steel of some properties also can be made to obtain certain physical and chemical performance, as quenching makes Permanent Magnet Steel strengthen its ferromegnetism, stainless steel can be made to improve its solidity to corrosion etc.
Larger quenching velocity is often required in quench cooled process, but (temperature of the hardening liquid around quenching workpiece is higher for the non-uniform temperature of hardening liquid in quench cooled process, the temperature comparatively end from the hardening liquid away from quenching workpiece), hardening liquid poor fluidity, lack cooling source, cause quenching efficiency lower, also have a strong impact on the effect of quenching.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, a kind of two cooling heat treatment quenching tank is provided, this device has circulating cooling system and spiral cooling tube circulating cooling system simultaneously, the two collaborative work that combines can reach the effect of efficient uniform cooling, to raising quenching efficiency, ensures that quenching effect has very great help.
The utility model is achieved through the following technical solutions:
Two cooling heat treatment quenching tank comprises one for holding a tank body for quenching fluid,
Described tank body is columnar structured, in the inside of tank body, inner tank wall is provided with spiral cooling tube, spiral cooling tube is provided with spiral cooling tube water-in and spiral cooling tube water outlet, and spiral cooling tube water-in is connected cooling water circulation waterworks with spiral cooling tube water outlet through tank wall;
The bottom of tank wall is provided with circulation liquid outlet, and the top of tank wall is provided with circulation fluid inlet, and circulation liquid outlet is connected by circulating line with circulation fluid inlet, and on circulating line, be provided with recycle pump and cooling heat exchanger;
The top of tank body is provided with spilling groove;
The top sidewall of tank body is also provided with blower fan of bleeding.
In technique scheme, described circulation liquid outlet is arranged on the sidewall bottom of tank body.
In technique scheme, described circulation fluid inlet is arranged on the sidewall top of tank body.
Advantage of the present utility model and beneficial effect are:
ON cycle pump in quenching process, the fluid in tank body (or other quenching liquid) is made to carry out circulating cooling by circulating cooling system, promote the flowing of fluid, make the equalizing temperature of tank body inner fluid, thus raising quenching efficiency, prevent the temperature of the hardening liquid around because of workpiece from differing simultaneously and cause workpiece deformation and produce excessive internal stress; In spiral cooling tube, pass into recirculated cooling water by cooling water circulation waterworks, by the heat exchange effect of spiral cooling tube, the fluid in tank body is lowered the temperature, to improve quenching efficiency, ensure quenching effect; Because the utility model has circulating cooling system and spiral cooling tube circulating cooling system simultaneously, the two collaborative work that combines can reach the effect of efficient uniform cooling, to raising quenching efficiency, ensures that quenching effect has very great help.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Wherein: 1 is tank body, 2 is spiral cooling tube, and 2-1 is spiral cooling tube water-in, and 2-2 is spiral cooling tube water outlet, 3 for overflowing groove, and 4-1 is circulation liquid outlet, and 4-2 is circulation fluid inlet, and 4-3 is circulating line, 4-4 is recycle pump, and 4-5 is heat exchanger, and 5 is blower fan of bleeding.
Embodiment
The technical solution of the utility model is further illustrated below in conjunction with specific embodiment.
Two cooling heat treatment quenching tanks involved by the utility model comprise one for holding the tank body 1 of quenching fluid,
Described tank body 1 is columnar structured, in the inside of tank body, inner tank wall is provided with spiral cooling tube 2, spiral cooling tube 2 is provided with spiral cooling tube water-in 2-1 and spiral cooling tube water outlet 2-2, and spiral cooling tube water-in 2-1 is connected cooling water circulation waterworks (not marking in figure) with spiral cooling tube water outlet 2-2 through tank wall;
The bottom of tank body 1 sidewall is provided with circulation liquid outlet 4-1, the top of tank body 1 sidewall is provided with circulation fluid inlet 4-2, circulation liquid outlet is connected by circulating line 4-3 with circulation fluid inlet, and on circulating line 4-3, be provided with recycle pump 4-4 and cooling heat exchanger 4-5, form circulating cooling system;
The top of tank body 1 is provided with overflows groove 3;
The top sidewall of described tank body 1 is also provided with blower fan 5 of bleeding.
ON cycle pump in quenching process, the fluid in tank body (or other quenching liquid) is made to carry out circulating cooling by circulating cooling system, promote the flowing of fluid, make the equalizing temperature of tank body inner fluid, utilize heat exchanger 4-5 to carry out radiating and cooling simultaneously, thus raising quenching efficiency, prevent the temperature of the hardening liquid around because of workpiece from differing simultaneously and cause workpiece deformation and produce excessive internal stress;
In spiral cooling tube, pass into recirculated cooling water by cooling water circulation waterworks, by the heat exchange effect of spiral cooling tube, the fluid in tank body is lowered the temperature, to improve quenching efficiency, ensure quenching effect;
Because the utility model has circulating cooling system and spiral cooling tube circulating cooling system simultaneously, the two collaborative work that combines can reach the effect of efficient uniform cooling, to raising quenching efficiency, ensures that quenching effect has very great help.
Above exemplary description is done to the utility model; should be noted that; when not departing from core of the present utility model, any simple distortion, amendment or other those skilled in the art can not spend the equivalent replacement of creative work all to fall into protection domain of the present utility model.
