Description

Technical Field

[0001] The utility model relates to the technical field of cooling devices, in particular to an atomization powder making cooling device. Background Art

[0002] The preparation technology of spherical metal alloy powder mainly includes gas atomization technology, rotating electrode atomization technology and plasma spheroidization technology. Among them, the powder collection tank is an important part of all powder making devices, which plays the role of collecting and cooling the produced powder. However, the conventional powder collection tank is a simple double-layer water-cooled tank body, which cools the powder by heat conduction from the tank body. This design has a certain cooling effect when the amount of powder is small or the temperature of the powder after atomization is low; but when the amount of powder is large or the temperature of the atomized metal powder is high, especially when preparing large-particle powder with a slow cooling rate.

[0003] Traditional powder collection tanks have poor cooling effects on powders, which causes large-particle powders to easily agglomerate and clump, and even cause adhesion between powders to form "satellite powders", which seriously affects the quality of the final metal powder. Utility Model Content

[0004] In view of the shortcomings of the prior art, the utility model provides an atomizing powder making cooling device, which overcomes the shortcomings of the prior art and effectively solves the problem that the traditional powder collection tank in the prior art has a poor cooling effect on the powder, which causes large particle size powder to easily agglomerate and agglomerate, and even adhesion between the powders to form "satellite powder", thereby seriously affecting the quality of the final metal powder.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] The fan sends the metal powder that has not been completely cooled in the cooling tower into the cooling cylinder, extending the cooling path of the metal powder. The coolant in the water tank circulates through the water pump along the outlet pipe, two fixed pipes, and the water inlet pipe in the water tank and the cooling cylinder cavity, thereby reducing the temperature in the cooling cylinder and cooling the metal powder flowing with the air in the cooling cylinder. The servo motor drives the spiral conveyor roller to rotate, conveying the metal powder attached to the inner wall of the cooling cylinder, and finally dropping the metal powder through the discharge pipe to the collection cylinder for collection.

[0008] Preferably, a through hole is provided at the bottom end of the outer wall of one side of the cooling tower, and the through hole is adapted to the specifications of the cooling cylinder.

[0009] The interior of the cooling tower and the cooling cylinder are communicated with each other.

[0010] Preferably, a filter ring is inserted into the top end of the air outlet pipe, and the air outlet pipe is located directly above the discharge pipe.

[0011] The filter ring is provided to filter the metal powder flowing with the air, thereby preventing the metal powder from being discharged along the air outlet pipe.

[0012] Preferably, a collecting cylinder is inserted into the bottom of the discharge pipe, and brackets are connected to both ends of the bottom of the cooling cylinder.

[0013] The metal powder falls down along the discharge pipe into the collecting cylinder for collection, and the two brackets can support and stabilize the cooling cylinder.

[0014] Preferably, a cavity is provided between the outer wall and the inner wall of the cooling cylinder, and the two fixed pipes are interconnected with the cavity.

[0015] The coolant circulates in the cavity of the cooling cylinder through two fixed pipes.

[0016] Preferably, the top end of the water outlet pipe and the top end of the water inlet pipe are respectively plugged into the bottom ends of the two fixed pipes.

[0017] The coolant in the water tank flows in and out of two fixed pipes through the water outlet pipe and the water inlet pipe.

[0018] The beneficial effects of the utility model are:

[0019] The metal powder that has not been completely cooled in the cooling tower is sent into the cooling cylinder through the fan to extend the cooling path of the metal powder. The coolant in the water tank circulates in the cavity of the water tank and the cooling cylinder, thereby reducing the temperature in the cooling cylinder and cooling the metal powder flowing with the air in the cooling cylinder. The servo motor drives the spiral conveyor roller to rotate to convey the metal powder attached to the inner wall of the cooling cylinder, and finally the metal powder falls into the collecting cylinder through the discharge pipe for collection. This effectively solves the problem that the traditional powder collection tank in the prior art has a poor cooling effect on the powder, which leads to large-particle powder being easily agglomerated and agglomerated, and even the powders are bonded to form "satellite powder", which seriously affects the quality of the final metal powder.
