Description

Technical Field

[0001] This utility model relates to the field of drying technology, specifically a spray drying tower for mixing cemented carbide rod powder. Background Technology

[0002] Cemented carbide rods, also known as tungsten carbide rods, are composite materials produced by powder metallurgy, consisting of refractory metal compounds and binder metals. Cemented carbide rod powder is the raw material for manufacturing cemented carbide rods, mainly composed of hard compounds of refractory metals and binder metal powders. Cemented carbide has a hardness second only to diamond and possesses very high compressive and bending strength. Due to its excellent properties, cemented carbide rods are widely used in many fields: cutting tools, such as lathe tools, milling cutters, planing tools, drill bits, boring tools, etc., for cutting various metals and non-metals; mining tools, used in mining and tunneling operations; measuring tools, used to manufacture measuring instruments and precision parts; and wear-resistant parts, used to manufacture components that need to withstand high wear, such as cylinder liners and precision bearings.

[0003] Spray drying technology is characterized by its rapid drying speed, completing the drying process in just a few seconds. This makes the preparation of cemented carbide rod powder more efficient, significantly shortening the production cycle. Furthermore, the operation and control of the spray drying tower are convenient, simplifying the production process and reducing manual intervention and production costs. During this process, the particle size, purity, and uniformity of the powder can be well controlled. For cemented carbide, the uniformity and purity of the powder have a significant impact on the alloy's performance. The spray drying tower ensures uniform powder distribution and high purity, thereby improving the formability and density of cemented carbide.

[0004] Therefore, a spray drying tower for mixing cemented carbide rod powder is proposed. Utility Model Content

[0032] One end of the air inlet duct 525 is connected to the outer wall of the drying chamber 1, and a filter screen is provided on the inner wall of one end of the air inlet duct 525.

[0033] Furthermore, in this embodiment, the operation of the blower 521 and the air heater 524 allows the blower 521 to draw in the air filtered by the air filter 522, and then deliver it to the air heater 524 for heating through the air supply pipe 523. The heated air is then delivered to the drying chamber 1 through the air inlet pipe 525. At this time, the liquid delivery pump 513 is started.

[0036] Furthermore, in this embodiment, by activating the cyclone separator 611, the operation of the cyclone separator 611 draws in the exhaust gas and fine powder in the drying chamber 1 through the connecting pipe 613 and separates them, causing the fine powder to fall into the collection bottle 614. The exhaust gas is then transported to the bag filter 616 through the connecting pipe 615, where it is filtered. The exhaust fan 6110 is then activated to draw in the filtered gas through the suction pipe 619 and discharge it through the exhaust pipe 6111, thereby achieving the effect of recovering and treating the exhaust gas and fine powder.

[0037] In operation, the blower 521 draws in air filtered by the air filter 522 and delivers it to the air heater 524 via the air supply pipe 523 for heating. The heated air is then delivered to the drying chamber 1 via the air inlet pipe 525. At this time, the liquid delivery pump 513 is started, drawing liquid from the liquid tank 511 through the suction pipe 514 and delivering it to the atomizing nozzle 4 via the delivery pipe 515. The atomizing nozzle 4 is then started to atomize the liquid and spray it out to contact the hot air in the drying chamber 1. This causes the droplets to dry rapidly into powder under the action of hot air and fall into collection bottle 3. When the cyclone separator 611 is started, the operation of the cyclone separator 611 draws in the exhaust gas and fine powder in the drying chamber 1 through the connecting pipe 613 and separates them, so that the fine powder falls into collection bottle 614. The exhaust gas is transported to the bag filter 616 through the connecting pipe 615 and then filtered through the bag filter 616. Then the exhaust fan 6110 is started to draw in the filtered gas through the suction pipe 619 and then discharge it through the exhaust pipe 6111, thereby achieving the recovery and treatment of exhaust gas and fine powder.
