Description

Technical Field

[0001] The utility model relates to the technical field of spray drying towers, in particular to a high-efficiency and energy-saving latex powder spray drying tower. Background Art

[0002] The latex powder spray drying tower is a device specially used to convert liquid latex powder raw materials into solid latex powder through a spray drying process. The equipment is usually composed of a tower body, an atomizer, a hot air system, a cyclone separator and a collection system. It can efficiently complete the drying and collection of latex powder. At present, the latex powder spray drying tower adopts advanced hot air system and heat exchange technology to ensure full contact between hot air and atomized droplets, improve drying efficiency, and ensure high efficiency and energy saving.

[0003] Existing latex powder spray drying towers, such as the one disclosed in publication number CN216092269U, are a type of spray drying tower for producing latex powder. A transmission cartridge drives a scraper to quickly scrape the inner wall of the drying tower to clean the inner wall of the tower. This structure for cleaning the inner wall of the tower body easily causes powder particles attached to the inner wall of the tower body to stick to the inner wall of the tower body and the upper end of the scraper. This requires additional cleaning of the sticky parts of the inner wall of the tower body and the sticky parts of the scraper. To this end, we propose an efficient and energy-saving latex powder spray drying tower. Utility Model Content

[0028] Specifically, the latex powder spray drying tower is a device specially used to convert liquid latex powder raw materials into solid latex powder through a spray drying process. At present, the latex powder spray drying tower adopts advanced hot air system and heat exchange technology to ensure that the hot air is fully in contact with the atomized droplets, improve the drying efficiency, and ensure high efficiency and energy saving; the first air outlet ring 201 and the second air outlet ring 202 installed on the upper and lower sides and the middle of the inner wall of the tower body 100 can extract a part of the hot air through the air supply device 101 when the latex powder is spray dried in the tower body 100, and then the hot air is discharged through the main pipe 206 and the branch pipe 205. The hot air is transported to the interior of the first air outlet ring 201 and the second air outlet ring 202 in the tower body 100, and the hot air transported to the interior of the first air outlet ring 201 and the second air outlet ring 202 is continuously blown out to the inner wall of the tower body 100 through the multiple groups of air outlet holes 204 arranged at the bottom, thereby avoiding the sticking and adhesion of the latex powder to the inner wall of the tower body 100 during spray drying. The arc edge 209 set on the upper end face of the second air outlet ring 202 can also make the powder particles blown out from the inner wall of the middle part of the tower body 100 slide through the arc edge 209 to the center of the tower body 100, and then fall down for collection after being dried again.

[0029] Example 2:

[0030] Combine Figure 5 As shown, on the basis of embodiment one, the adjustment component 300 includes a sealing plate 301 movably installed in the air cavity 203 in the first air outlet ring 201 and the second air outlet ring 202, a connecting rod 302 fixed on both sides of the multiple groups of sealing plates 301, and an electric rod 303 fixedly installed on the top of the tower body 100, and the tops of the connecting rods 302 are fixedly connected. Mounting holes 304 are also opened on both sides of the first air outlet ring 201 and the second air outlet ring 202, and the connecting rod 302 is movably matched and installed in the mounting hole 304. The cross section of the sealing plate 301 is the same as the cross section of the air cavity 203.

[0031] Specifically, the sealing plate 301 inside the first air outlet ring 201 and the second air outlet ring 202 can be moved downward under the drive of the electric rod 303 to block the air outlet holes 204 at the bottom of the first air outlet ring 201 and the second air outlet ring 202, thereby avoiding the problem of dirt entering the first air outlet ring 201 and the second air outlet ring 202 when the first air outlet ring 201 and the second air outlet ring 202 are not in use.

[0032] The working principle and use process of this utility model:

[0033] When the latex powder is spray-dried in the tower body 100, the blower 207 started at the lower end of the air supply device 101 will extract part of the hot air in the air supply device 101, and transport the hot air to the first air outlet ring 201 and the second air outlet ring 202 at the upper and lower ends of the tower body 100 through the main pipe 206 and the multiple groups of branch pipes 205 at the bottom. The hot air is blown out through the multiple groups of air outlet holes 204 arranged at the bottom of the first air outlet ring 201 and the second air outlet ring 202. The hot air blown out from the air outlet holes 204 will blow down along the inner wall of the tower body 100, and during the continuous downward blowing, the powder particles attached to the inner wall of the tower body 100 will be blown out to prevent them from sticking to the tower body 100. The inner wall, the arc edge 209 set at the upper end of the second air outlet ring 202 can also allow the powder at its upper end to slide along the arc edge 209 to the center of the tower body 100 after being blown away for drying again. When the first air outlet ring 201 and the second air outlet ring 202 are not in use, the electric rods 303 on both sides of the top of the tower body 100 can also be started to drive the connecting rod 302 at the bottom to move downward, so as to move the sealing disk 301 on the connecting rod 302 down to the bottom of the air cavity 203 in the first air outlet ring 201 and the second air outlet ring 202, thereby sealing the multiple groups of air outlet holes 204 at the bottom of the air cavity 203, thereby avoiding the problem of dirt inside the air cavity 203.
