Description

Technical Field

[0001] The utility model relates to the technical field of spray drying tower discharging, in particular to a spray drying tower discharging device. Background Art

[0002] Spray drying tower is a common drying equipment, usually used to convert liquid materials into powder or granular state. The working principle of the spray drying tower is to atomize the liquid material into tiny droplets through a nozzle or atomizer, and then contact these droplets with hot air flow. In this process, the water or solvent in the droplets will evaporate, leaving solid particles or powder.

[0003] In order to facilitate discharging, the discharge port of the equipment is usually funnel-shaped. Since the material is generally granular, while the material has fluidity, it also makes it easy for the material to be blocked at the discharge port. When the material is dried into granules, the sizes of the particles are different. Particles that are too large do not meet the requirements. The staff also need to manually screen them, which causes a waste of resources. Utility Model Content

It is placed on the right side of the tower body 1, the screening mechanism 5 is arranged inside the tower body 1, and a motor 16 is fixedly installed inside the support platform 12. The output end of the motor 16 is fixedly connected to the top of the first rotating rod 301. By setting the discharging mechanism 3, the staff starts the motor 16 to drive the first rotating rod 301 to rotate, and the spiral blade 303 is rotated at the same time through the fixed connection of the connecting rod 302. Since the shape of the spiral blade 303 is set to be spiral and has a downward trend, the spiral blade 303 stirs the granular material at the discharging port, thereby avoiding the phenomenon of material blocking the discharging port;

[0034] Reference Figure 1-4 The screening mechanism 5 includes a filter plate 501, a stirring blade 502 and a screening port 503. The filter plate 501 is fixedly mounted on the inner wall of the tower body 1, the stirring blade 502 is fixedly mounted on the surface of the first rotating rod 301, and the screening port 503 is opened on the inner wall of the tower body 1. By setting the screening mechanism 5, the material is intercepted by the filter plate 501 during the process of falling into granular form. Since the filter plate 501 has filter holes on its surface, the material that meets the requirements continues to fall, and the oversized material is intercepted at the top of the filter plate 501. The first rotating rod 301 rotates while driving the stirring blade 502 to rotate. The first rotating rod 301 is sleeved inside the filter plate 501 and is rotatably connected to the filter plate 501. After the valve 8 is opened, the oversized material enters the first air pipe 6 from the screening port 503 through the cooperation of the stirring blade 502, so that there is no need for manual screening. The screening work can be completed while the equipment is running, thereby improving work efficiency.

[0035] Reference Figure 1-4The left side of the tower body 1 is fixedly installed with a first air pipe 6 and a support block 7, the inner cavity of the first air pipe 6 is connected with the inner cavity of the screening port 503, the support block 7 is sleeved on the surface of the first air pipe 6, and is fixedly connected to the first air pipe 6, a valve 8 is installed at the bottom of the first air pipe 6, an air pump 9 is installed at the other end of the first air pipe 6, a second air pipe 10 is fixedly installed on the right side of the air pump 9, and the other end of the second air pipe 10 passes through the cavity 2, and a second rotating rod 13 is rotatably installed at the bottom of the support platform 12, the second rotating rod 13 is sleeved inside the first air pipe 6, and a valve 8 is fixedly installed on the surface of the second rotating rod 13. The surfaces of the first rotating rod 301 and the second rotating rod 13 are both equipped with rotating wheels, and a transmission belt 15 is provided between the first rotating rod 301 and the second rotating rod 13 through a rotating wheel sleeve. By setting the second rotating rod 13 and starting the vacuum pump 9, the material in the first air pipe 6 moves upward. Through the cooperation of the transmission belt 15, the first rotating rod 301 rotates and drives the second rotating rod 13 to rotate, so that the breaking leaves 14 rotate at the same time, so that the material is broken into smaller particles in the process of moving upward, and then enters the tower body 1 again through the vacuum pump 9 and the second air pipe 10, so that the oversized particles can be recycled and reused.

[0036] Specifically, the working process or working principle of the spray drying tower discharge device is as follows: when in use, the staff starts the motor 16 to drive the first rotating rod 301 to rotate, and the spiral blade 303 is rotated at the same time through the fixed connection of the connecting rod 302. Since the shape of the spiral blade 303 is set to be spiral and has a downward trend, the spiral blade 303 stirs the granular material at the discharge port. In the process of the material becoming granular and falling, it is intercepted by the filter plate 501. Since the surface of the filter plate 501 is provided with filter holes, the material that meets the requirements continues to fall, and the excessively large material is blocked. The material is intercepted at the top of the filter plate 501, and the first rotating rod 301 rotates while driving the stirring blade 502 to rotate. After the valve 8 is opened, the oversized material enters the first air pipe 6 from the screening port 503 through the cooperation of the stirring blade 502, and the vacuum pump 9 is started. The material in the first air pipe 6 moves upward. Through the cooperation of the transmission belt 15, the first rotating rod 301 rotates while driving the second rotating rod 13 to rotate, and the breaking blade 14 rotates at the same time, so that the material is broken into smaller particles in the process of moving upward, and then enters the tower body 1 again through the vacuum pump 9 and the second air pipe 10.

[0037] It should be noted that the motor 16 and the vacuum pump 9 are devices or equipment existing in the prior art, or are devices or equipment that can be realized in the prior art. Their power supply, specific composition and principles are clear to those skilled in the art, so they are not described in detail.
