[0002] Vacuum furnace heat treatment is a process that heats the material to a high temperature and then controls the cooling to change the physical, chemical and mechanical properties of the material. Vacuum furnace heat treatment is generally used for the treatment of metals, alloys and other materials. It should be noted that cooling too fast or too low a temperature will have adverse effects.

[0003] The existing patent document with publication number CN215766517U discloses a vacuum smelting furnace cooling device, including a cooling device, the cooling device including an air-cooling cooling device, a water-cooling cooling device and a vacuum smelting furnace, the air-cooling cooling device including a motor and blades, the water-cooling cooling device including a cooling box, a water inlet, a water outlet, a water pump, a filter, a water exchange port, a valve, a water inlet pipe, a water outlet pipe and a cooling pipe, and the filter is movably installed at the other end of the water pump.

[0004] The above equipment has the following problems when in use:

[0005] (1) Water cooling of existing equipment is generally achieved through a serpentine pipe wrapped around the cylinder. On the one hand, this method has a limited heat dissipation contact area, which affects the heat dissipation rate. On the other hand, the heat dissipation at the front and rear ends is uneven, and the end connected to the water inlet has a better heat dissipation effect, resulting in uneven internal heat loss, which affects the sintering effect.

[0006] (2) In order to ensure the sintering effect, the cooling curve also needs to be controlled. The cooling effect of the existing cooling device cannot be adjusted according to actual needs.

[0007] To this end, we propose an adjustable vacuum smelting furnace cooling device to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] See also Figures 1 to 6 , an adjustable vacuum smelting furnace cooling device, comprising a water tank 1, a heating chamber 2 and a vacuum box 3, a circulating pump 4 is arranged on the water tank 1, a conveying pipe 6 and a discharge pipe 7 are connected to the circulating pump 4 through flanges 5, and the flanges 5 can ensure the sealing of the connection;

[0032] The water tank 1 is filled with coolant, which enters the device through the delivery pipe 6 and is discharged from the discharge pipe 7 after absorbing heat. The circulation pump 4 is used to allow the coolant to circulate smoothly.

[0033] A heat exchange tube 9 is fixedly mounted on the outer wall of the heating chamber 2, and a flow divider 8 and a flow collector 10 are fixedly mounted on the heat exchange tube 9;

[0034] The heat exchange tube 9 is directly attached to the heating chamber 2, and the heat dissipation area is larger, which can ensure the heat dissipation effect.

[0035] Liquid inlet pipes 13 are evenly and evenly fixed on the heat exchange tube 9, and a fixing plate 16 is fixedly installed on the liquid inlet pipe 13. A fixing port 17 is opened on the fixing plate 16, and the coolant flows into the heat exchange tube 9 through the fixing port 17;

[0036] The coolant can enter the heat exchange cylinder 9 synchronously from the multiple liquid inlet pipes 13, thereby ensuring the uniformity of the internal fluid and making the heat dissipation effect more uniform.

[0037] A gear 18 is rotatably mounted on the fixed plate 16, and an adjustment port 19 is provided on the gear 18;

[0038] The rotation of the gear 18 can change the position of the adjusting port 19 , that is, the position of the adjusting port 19 changes relative to the fixed port 17 .

[0039] When the gear 18 rotates, the exposed area of ​​the fixed port 17 is changed, that is, the space available for the coolant to enter is also changed, so the amount of coolant entering can be controlled, thereby accurately adjusting the heat dissipation curve.

[0040] A rack 20 is slidably mounted on the heat exchange tube 9 , a connecting plate 21 is fixedly mounted on one end of the rack 20 , a telescopic rod 22 is fixedly mounted on the connecting plate 21 , and the other end of the telescopic rod 22 is fixedly mounted on the diverter cover 8 .

[0041] The activation of the telescopic rod 22 can drive the rack 20 to move synchronously, and the movement of the rack 20 can cause the gear 18 to rotate.

[0042] The size and shape of the adjustment opening 19 and the fixed opening 17 are completely the same, and the adjustment opening 19 can adjust the shielded area of ​​the fixed opening 17 .

[0043] When the regulating port 19 and the fixed port 17 completely overlap, the flow rate is at a maximum. When the regulating port 19 and the fixed port 17 do not overlap at all, the coolant cannot flow through. The overlap range between the regulating port 19 and the fixed port 17 is zero to one hundred percent.

[0044] The rack 20 is in meshing relationship with the plurality of gears 18 , so the movement of the rack 20 can cause the plurality of gears 18 to rotate synchronously, thereby synchronously adjusting the exposed size of the fixing opening 17 .

[0045] The delivery pipe 6 is connected to the flow distribution cover 8 and the discharge pipe 7 is connected to the collecting cover 10 .

[0046] The heating chamber 2 is respectively penetrated and embedded with an argon inlet 11 and an argon outlet 12 at both ends. Argon is introduced into the heating chamber 2 through the argon inlet 11, and argon is discharged from the argon outlet 12. Part of the heat can be removed by air cooling, thereby achieving heat dissipation and cooling activities.

[0047] A shielding plate 14 is embedded and installed inside the heat exchange tube 9 , and vents 15 are evenly and equidistantly formed on the shielding plate 14 .

[0048] The existence of the shielding plate 14 can block the running track of the argon gas, and only a part of the argon gas can flow out smoothly through the vent 15. The shielding plate 14 can effectively prolong the time that the argon gas stays inside, so that the heat exchange is more complete and the cooling effect is better.

[0049] Adjacent shielding plates 14 are installed in a staggered manner, and the shielding plates 14 are in communication with the heat exchange tube 9 .

[0050] The interior of the baffle plate 14 is hollow, and the coolant can smoothly enter the baffle plate 14, so that the contact area for heat dissipation is larger, and the plate with the vents 15 can slow down the speed at which the coolant falls, and can further ensure the cooling effect.

[0051] The working process of the utility model is as follows: when heat dissipation and cooling activities are required, the circulation pump 4 is turned on, and the coolant inside the water tank 1 enters the diverter cover 8 through the delivery pipe 6, and then flows into the heat exchange tube 9 through the fixed port 17. The heat exchange tube 9 is directly fitted with the heating chamber 2, and the heat dissipation area is larger, which can ensure the heat dissipation effect.

[0052] When the cooling curve needs to be regulated, the activation of the telescopic rod 22 can drive the rack 20 to move synchronously. The movement of the rack 20 can cause the gear 18 to rotate. When the gear 18 rotates, the exposed area of ​​the fixed port 17 is changed, that is, the space for the coolant to enter is also changed, so the amount of coolant entering can be controlled, thereby accurately regulating the heat dissipation curve.

[0053] When rapid cooling is required, argon is introduced into the heating chamber 2 through the argon inlet 11 and discharged through the argon outlet 12. Part of the heat can be removed by air cooling. The baffle 14 can block the trajectory of the argon, and only part of the argon can flow out smoothly through the vent 15. The baffle 14 can effectively prolong the time that the argon stays inside, thereby achieving more complete heat exchange and better cooling effect.
