The cooling water pipe 10 is supplied with water from a cooling water pipe inlet 10-1 at one end and returns water from a cooling water pipe outlet 10-2 at the other end. The condenser is provided with a plurality of air inlet pipes 12 that pass through the stainless steel water-cooling interlayer 9 to ventilate the condenser.

[0020] The outer walls of the heating source 1, the collector 3 and the filter tank 4 are all provided with a stainless steel water-cooling interlayer 9. The stainless steel water-cooling interlayer 9 provided on the outer wall of the heating source 1 and the outer layer of the condenser are all independent stainless steel water-cooling interlayers. The stainless steel water-cooling interlayer 9 on the outer wall of the heating source 1 is respectively provided with a water-cooling interlayer water inlet (not shown in the figure) and a water-cooling interlayer water outlet (not shown in the figure). The stainless steel water-cooling interlayer 9 on the outer layer of the condenser is respectively provided with a water-cooling interlayer water inlet 13 and a water-cooling interlayer water outlet 14.

[0021] The stainless steel water-cooling interlayer 9 of the collector 3 and the filter tank 4 are interconnected, a water-cooling interlayer water inlet 13 is provided on the bottom stainless steel water-cooling interlayer 9 of the collector 3 and the filter tank 4, a water-cooling interlayer water outlet 14 is provided on the upper stainless steel water-cooling interlayer 9 of the filter tank 4, there are multiple collectors 3, the collector 3 is a cyclone collector, the filter tank 4 is a cyclone collection filter tank, and a filter bag 15 is also provided on the top of the filter tank 4.

[0022] Specific usage process: In actual use, turn on the heating source 1 and the blower (not shown in the figure), the gas enters the high-temperature metal evaporator 2 from the air inlet 6, and the powder to be classified enters the high-temperature metal evaporator 2 from the feeding port 5. After the powder enters the condenser from the high-temperature metal evaporator 2, it continues to enter the multiple cyclone collectors 3. Part of the powder falls to the bottom of the cyclone collector 3 under the action of gravity and is collected and graded by the discharge ports 7 of the multiple cyclone collectors 3. The remaining powder continues to enter the cyclone collection filter tank 4, the heavier powder falls and is collected by the discharge port 7 of the cyclone collection filter tank 4, the lighter powder is collected by the filter bag 15 at the top of the filter tank 4, and the gas enters the blower (not shown in the figure) from the air outlet 8 at the top of the filter tank 4 for continued use. During this process, the condenser is ventilated separately through multiple air inlet pipes 12 at the same time, and the gas enters the coiled plate porous tube 11 through the air inlet pipe 12 and the circular hole 11-1 on the coiled plate porous tube 11 in turn. At the same time, the cooling water pipe 10 in the condenser is independently supplied with water from the cooling water pipe inlet 10-1 at one end, and then returned to the water tower (not shown in the figure) for cooling through the cooling water pipe outlet 10-2 at the other end; the stainless steel water-cooling interlayer 9 arranged on the outer layer of the condenser is independently supplied with water, and water is supplied from the water-cooling interlayer water inlet 13 and discharged from the water-cooling interlayer water outlet 14 to the water tower (not shown in the figure) for cooling; the stainless steel water-cooling interlayer 9 at the bottom of the collector 3 and the filter tank 4 is independently supplied with water from the water-cooling interlayer water inlet 13, and then discharged from the filter tank water-cooling interlayer water outlet 14 to the water tower (not shown in the figure) for cooling. Finally, all the cooling water enters the system through the integrated water supply pump (not shown in the figure) for recycling.

The front section condenser of the utility model has reduced the temperature to a sufficiently low level, and the stainless steel water-cooled interlayer of the collector and the filter tank is connected. There is no need to set a separate water outlet for the water-cooled interlayer on the collector. The water is fed into the water-cooled interlayer water inlet on the bottom stainless steel water-cooled interlayer of the collector and the filter tank, and then the water is discharged from the water outlet of the filter tank and returned to the water tower for cooling. Finally, all the cooling water enters the system through the integrated water supply pump and is recycled, reducing the production cost of the enterprise; the multiple collectors 3 and filter tanks 4 are set up to collect the powder in a graded manner, making the powder preparation more refined and improving the quality of the powder. There is no need for manual grading or sending it to a professional organization for grading, which not only reduces the cost of powder preparation but also saves time and improves the efficiency of powder preparation.
