Embodiment Construction
[0018] Example: see figure 1 , 2 As shown, the stirring cooling system for heat treatment and quenching includes a pool body 1, a mixer 2 and a water cooling system 3. The pool body 1 is respectively connected to the water inlet and water outlet of the water cooling system 3 through a water inlet pipe 4 and an outlet pipe 5, and the mixer 2 is fixed on the On the mixer frame 6, the lower part of the mixer frame 6 is fixed with a guide tube 7, and the guide tube 7 is placed in the pool body 1;
[0019] Three mixers 2 are fixed on the mixer frame 6, and two partitions 9 are fixed on the guide tube 7, and the two partitions 9 divide the guide tube 7 into three chambers, namely the left chamber 71, the middle chamber 72 and the left chamber 72. Right chamber 73, a stirring impeller 21 of mixer 2 is arranged in each chamber;
[0020] The left chamber 71 has a left chamber water inlet 711 and an upper water outlet 712 of the left chamber, and the middle chamber 72 has a middle cha...

The invention discloses a stirring cooling system for heat treatment quenching. The stirring cooling system is characterized in that a left chamber is provided with a left chamber water inlet and a left chamber upper water outlet, a middle chamber is provided with a middle chamber water inlet and two triangular middle chamber upper water outlets which are close to baffle plates, and a right chamber is provided with a right chamber water inlet and a right chamber upper water outlet; the sizes of the left chamber, the middle chamber and the right chamber are the same, guide plates are fixedly arranged in the left chamber, the middle chamber and the right chamber, and both the left chamber upper water outlet and the right chamber upper water outlet are triangular openings; the water outlet directions of the left chamber upper water outlet, the middle chamber upper water outlets and the right chamber upper water outlet are upward, and the water inlet directions of the left chamber water inlet, the middle chamber inlet and the right chamber water inlet are from right to left. The stirring cooling system provided by the invention can rigidly control water velocity and water temperature in a heat treatment pool, and a condition that a casting is rapidly cooled in the heat treatment pool is ensured, so that the quality of the casting is improved.
Description
Technical field: [0001] The invention relates to the technical field of casting heat treatment equipment, in particular to a stirring cooling system for heat treatment, quenching and tempering. Background technique: [0002] The existing casting quenching or quenching and tempering heat treatment pool or the medium in the medium pool has no temperature and medium flow rate control, so when the casting is quenched or tempered, the cooling temperature is uneven, and the cooling time cannot meet the performance and hardness requirements. Thus affecting the service life of castings. Invention content: [0003] The object of the present invention is to address the deficiencies of the prior art, and provide a heat treatment system for casting quenching or quenching and tempering, which strictly controls the flow rate and temperature uniformity of water or medium in the heat treatment pool, thereby improving the heat treatment performance of castings, Extend the service life of ...
