[0027] The embodiment provides a quenching tank for air circulation furnace, specifically as shown in Figure 1 、 Figure 3 、 Figure 5 The quenching tank body 101 is an open-top box; a plurality of stirring pumps 102 are arranged on the quenching tank body 101, and the input end of the stirring pump 102 is connected to the top of the quenching tank body 101 and the output end is connected to the bottom of the quenching tank body 101.

[0028] The output end of the stirring pump 102 is connected with the spraying pipe 111, the spraying pipe 111 is in the shape of "T", and a plurality of spray holes are arranged on the spraying pipe 111; the supporting seat 109 is installed on the quenching tank body 101, and the supporting seat 109 is used for supporting the quenching tool 12.

[0029] When quenching the quenching tool 12 loaded with parts, the quenching tool 12 is placed into the quenching tank body 101 using hoisting equipment, at which time the liquid (oil, water or other medium, which can be selected according to actual needs) in the quenching tank body 101 cools the quenching tool 12. In order to ensure that the temperature distribution of the liquid in the quenching tank body 101 is uniform, the stirring pump 102 is started at this time. The stirring pump 102 extracts liquid from the upper layer of the quenching tank body 101 and then pumps it into the spouting pipe 111 at the bottom of the quenching tank body 101. The liquid is sprayed upward from the spray holes on the spouting pipe 111, and through the upward surge of the liquid, the stirring effect on the liquid in the quenching tank body 101 is achieved, preventing the problem of uneven temperature distribution of the liquid in the quenching tank body 101 during quenching of the quenching tool 12 loaded with parts, which leads to poor quenching quality.

[0030] Embodiment 2

[0031] This embodiment is further expanded on the basis of the above-mentioned embodiments, and specifically as shown in Figure 1 The quenching tank body 101 and the standby tank body 105 are provided with a first circulating pump 103 and a second circulating pump 104 therebetween.

[0032] When quenching the quenching tool 12 loaded with parts, if the temperature of the liquid in the quenching tank body 101 is too high, the first circulating pump 103 and the second circulating pump 104 are started at this time. The first circulating pump 103 pumps the liquid in the quenching tank body 101 into the standby tank body 105, and the second circulating pump 104 pumps the liquid in the standby tank body 105 into the quenching tank body 101. Through the first circulating pump 103 and the second circulating pump 104, the exchange of liquid between the quenching tank body 101 and the standby tank body 105 is achieved, thereby enhancing the heat dissipation effect of the liquid and preventing the problem of poor quenching quality caused by the excessively high temperature of the liquid in the quenching tank body 101.

[0033] The other parts of this embodiment are the same as those of the above-mentioned embodiments and will not be described again.
