Corrugated pipes 333 are fixed at both ends of the feed chamber 33 near the drying tower 3. The interior of the corrugated pipes 333 is hollow. Since the corrugated pipes 333 are movable parts, the operator can periodically shake the feed chamber 33. During this shaking, the scale inside the feed chamber 33 will sink to the bottom of the feed chamber 33, located on one side of the external pipe 332.

[0025] A connecting pipe 331 is provided on the side of the corrugated pipe 333 away from the feed chamber 33. The interior of the connecting pipe 331 is hollow and is used to connect the feed chamber 33, the corrugated pipe 333 and the interior of the drying tower 3 for feeding alumina granulation powder raw material. The side of the connecting pipe 331 away from the corrugated pipe 333 is detachably installed on the side wall of the drying tower 3, and an atomizing nozzle is detachably installed inside the drying tower 3. The working principle of the atomizing nozzle is mainly to squeeze the liquid into the nozzle through internal pressure. There is an iron plate inside the nozzle. The high-speed flowing liquid hits the iron plate and bounces back to form atomized particles with a diameter of about 15-60 micrometers, which are then sprayed out through the nozzle outlet.

[0026] An external pipe 332 is provided on the side of the feeding chamber 33 away from the drying tower 3, and the external pipe 332 is located below the connecting pipe 331 for feeding. When in use, the external pipe 332 will be connected to the external raw liquid tank. At this time, the operation of the feeding chamber 33 is controlled by the control panel. The feeding chamber 33 will transport the alumina granulation powder raw liquid inside the raw liquid tank to the drying tower 3 through the external pipe 332, the feeding chamber 33, the connecting pipe 331, the corrugated pipe 333 and the atomizing nozzle for processing, heating and drying.

[0027] The effect achieved by the whole embodiment one is that when the external pipe 332 is connected with the external raw solution tank, the feeding cavity 33 is controlled to work through the control panel at this time, the raw solution of the alumina granulation powder in the raw solution tank is transported to the drying tower 3 through the external pipe 332, the feeding cavity 33, the connecting pipeline 331, the corrugated pipe 333 and the atomizing nozzle for processing, since the corrugated pipe 333 is a movable part, the operator can shake the feeding cavity 33 regularly, at this time, the feeding cavity 33 will shake under the action of the corrugated pipe 333, at this time, the scale in the feeding cavity 33 will sink to the bottom of the feeding cavity 33 on the side of the external pipe 332, at this time, the internal pipe 332 can be separated from the external material tank, and the internal pipe 332 can be cleaned, so that the probability of blockage in the feeding cavity 33 is reduced, and the feeding cavity 33 is cleaned.

[0028] Embodiment two

[0029] As shown in Figs. 1-3 A spray drying device for producing alumina granulation powder, the surface of the drying tower 3 on one side of the feeding cavity 33 also has a dryer 34, wherein the working principle of the dryer 34 is mainly to make the moisture in the material vaporize and overflow by heating, so as to realize the drying effect, which is disclosed above, and will not be repeated below, and the output end of the dryer 34 extends into the drying tower 3, the dryer 34 is at the bottom of the whole device, and the output end of the dryer 34 extending into the drying tower 3 is evenly laid on the four circumferential side walls of the drying tower 3.

[0030] The drying tower 3 also has a preheater 31 on the opposite side of the feeding cavity 33, the output end and the input end of the preheater 31 extend into the drying tower 3, the position of the output end of the preheater 31 is higher than the position of the input end of the preheater 31, which is used for preheating the drying tower 3, and the working principle of the preheater 31 is mainly to heat the material by using waste heat, which is disclosed above, and will not be repeated below.

[0031] The top of the drying tower 3 has a detachable cover plate 32 for cleaning the drying tower 3, and the surface of the cover plate 32 is longitudinally provided with air holes 321 relative to the drying tower 3 for dispersing steam.

[0032] The bottom end of the drying tower 3 is provided with an air filtering cavity 4, which filters air by interception: when large dust particles are hit by fibers in the filter due to their size, they are intercepted, and the bottom end of the air filtering cavity 4 is detachably provided with a discharging pipe 5, and the bottom end of the discharging pipe 5 is connected with an air-powder separation chamber 2, and the outer surface of the air-powder separation chamber 2 is provided with a discharging pipe 21 for discharging material, which is used for loading and subsequent processing.

[0033] A base 1 is provided below the drying tower 3, and the top of the base 1 has a detachable support frame 11. The top of the support frame 11 is detachably connected to the outer wall of the drying tower 3 to support the drying tower 3.

[0034] The effect achieved by the entire embodiment 2 is that when the drying tower 3 is working, the dryer 34 will heat the material to vaporize and escape the moisture, thereby achieving the drying effect. Then, the preheater 31 will use the waste heat of the exhaust gas to heat the material. The heated alumina granulated powder will enter the gas-powder separation chamber 2 through the air filter chamber 4 and the feed pipe 5, and then be discharged through the discharge pipe 21 on one side of the gas-powder separation chamber 2.

[0035] Working principle: When using this spray drying device for alumina granulation powder production, an external power supply is connected. First, connect the external pipe 332 to the external raw liquid tank. At this time, the operation of the feeding chamber 33 is controlled through the control panel. The feeding chamber 33 will transport the alumina granulation powder raw liquid inside the raw liquid tank to the drying tower 3 through the external pipe 332, feeding chamber 33, connecting pipe 331, corrugated pipe 333 and atomizing nozzle for processing. Since the corrugated pipe 333 is a movable part, the operator can shake the feeding chamber 33 periodically. At this time, the feeding chamber 33 will shake under the action of the corrugated pipe 333. At this time, the scale inside the feeding chamber 33 will sink to the bottom of the feeding chamber 33, located on one side of the external pipe 332. At this time, the probability of blockage inside the feeding chamber 33 can be reduced by separating the external pipe 332 from the external material tank and cleaning the inside of the external pipe 332. At the same time, when cleaning the feeding chamber 33;

[0036] Secondly, when the drying tower 3 is working, the dryer 34 will heat the material to vaporize and overflow the moisture, thereby achieving the drying effect. Then, the preheater 31 will use the waste heat of the exhaust gas to heat the material. The heated alumina granulated powder will enter the air-powder separation chamber 2 through the air filter chamber 4 and the feed pipe 5. Then, the material will be discharged through the discharge pipe 21 on one side of the air-powder separation chamber 2, thus completing the operation of the spray drying device for the production of alumina granulated powder.
