[0002] The quenching of steel is a heat treatment process in which the steel is heated to a temperature above the critical temperature Ac3 (hypoeutectoid steel) or Ac1 (hypereutectoid steel), kept warm for a period of time to make it fully or partially austenitized, and then rapidly cooled to below Ms (or isothermally near Ms) at a cooling rate greater than the critical cooling rate to undergo martensite (or bainite) transformation, so as to greatly improve the rigidity, hardness, wear resistance, fatigue strength and toughness of the steel, thereby meeting the different use requirements of various mechanical parts and tools.

An anti-skid plate 12 is fixedly arranged on the end of the support column 11. By arranging the support columns 11 on the base plate 1, the support function of the entire device is realized. At the same time, each support column 11 is arranged at the corner of the base plate 1 so that each support column 11 can be evenly stressed during the support process, thereby avoiding damage to the support column 11 due to uneven stress during the support process. At the same time, the anti-skid plate 12 arranged on the bottom end of the support column 11 can increase the friction between the device and the ground, thereby avoiding the device from slipping during use.

By setting the reducer 4 on the bottom plate 1, when the staff starts the reducer 4, the hanging rod 43 fixedly arranged on the output end of the reducer 4 can process the impurities on the inner wall of the isolation cylinder 5.

[0038] Reference Figure 3-Figure 5 The transmission mechanism includes a fan blade 3212 fixedly arranged on the reciprocating screw rod 3211, and the fan blade 3212 is located in the pipette 321. By setting the fan blade 3212 on the reciprocating screw rod 3211, the solution flowing in the pipette 321 can drive the fan blade 3212 to rotate, thereby driving the reciprocating screw rod 3211 to rotate.

[0039] Reference Figure 4-Figure 6 The liquid outlet pipe 311 is located above the liquid suction pipe 321, and the liquid outlet pipe 311 is located above the liquid suction pipe 321 and is made of synthetic metal with strong thermal conductivity.

At the same time, each support column 11 is set at the corner of the bottom plate 1 so that each support column 11 can be evenly stressed during the support process, thereby avoiding damage to the support column 11 due to uneven stress during the support process. At the same time, the anti-skid plate 12 set on the bottom end of the support column 11 can increase the friction between the device and the ground, thereby avoiding the device from slipping during use. By setting the detection shell 22 on the shell 2, when the staff uses the device, the solution in the shell 2 passes through the connecting hole 227 to make the height of the solution in the two cavities the same, and by setting the shaft 2 on the detection shell 22 22 and the connecting plate 223 rotatably arranged on the shaft body 222, so that when the solution content in the detection shell 22 is too low, the position of the float 226 floating on the solution is lowered, so that the positive electrode 224 on the other end of the connecting plate 223 rises until the positive electrode 224 contacts the negative electrode 225 on the convex plate 221, thereby triggering an alarm to remind the staff that the solution content of the shell 2 is insufficient, the sleeve 61 arranged on the reciprocating screw rod 3211 and the scraper 62 fixedly arranged on the sleeve 61, so that the scraper 62 can scrape away the debris on the inner wall of the shell 2 when the sleeve 61 moves, and the reducer 4 arranged on the bottom plate 1, so that when the staff starts the reducer 4, the hanging rod 43 fixedly arranged on the output end of the reducer 4 can process the impurities on the inner wall of the isolation tube 5.
