DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-6, a multifunctional spray dryer provided by the present utility model includes: a tank body 1, and further includes: a hot air pipe 2 installed on the outer wall of the tank body 1. At both ends of the inner wall of the top of the hot air pipe 2, a flow splitting component 3 is connected. And a flow guiding component 4 is installed on the outer wall of the hot air pipe 2. A stirring component 5 is rotatably installed on the flow guiding component 4. And an exhaust component 6 is installed on the outer wall of the other side of the tank body 1. A collection box 7 is installed at the bottom of the tank body 1. And an atomizer 8 is installed on the inner wall of the top of the tank body 1. A liquid supply pipe 9 is connected to the top of the atomizer 8.

[0022] It should be noted here that: the liquid material can be input into the atomizer 8 through the liquid supply pipe 9, and the liquid mist is sprayed out through the atomizer 8. At the same time, hot air is introduced into the hot air pipe 2, and the hot air is sprayed out from the two flow splitting components 3 and blows on the liquid mist for drying. Through the arranged flow guiding component 4, the liquid mist can flow along the space between the flow guiding component 4 and the inner wall of the tank body 1 after being sprayed out. The flow guiding component 4 itself has a heating function and can heat and dry the mist droplets blowing on its surface, separating the conical liquid mist from the middle to avoid that the mist droplets inside the conical shape may be difficult to fully contact with the hot air, affecting the drying effect. At the same time, when the hot air flows in the hot air pipe 2, it will blow the stirring component 5 to rotate. The stirring component 5 will stir the hot air flow sprayed out by the flow splitting component 3 and the liquid mist together, making the contact between the liquid mist and the hot air flow more sufficient, which can further improve the drying effect. After drying, the powder falls into the collection box 7, and the gas in the tank body 1 is discharged through the exhaust component 6. The filtering structure at the bottom of the exhaust component 6 can filter the discharged air flow to avoid taking away too much powder. At the same time, when the stirring component 5 rotates, it can scrape the filtering structure at the bottom of the exhaust component 6 to conveniently scrape off the filtered powder and ensure the filtering effect.

[0023] In a preferred embodiment, the flow splitting component 3 includes a vertical pipe 301, a plurality of equally spaced flow splitting pipes 302 connected to the inner wall of one side of the vertical pipe 301, and a nozzle 303 installed at one end of the flow splitting pipe 302.

[0024] It should be noted here that: the hot air enters the vertical pipe 301 through the hot air pipe 2, then enters the flow splitting pipes 302 and is sprayed out from the nozzles 303.

[0025] In a preferred embodiment, the flow guiding component 4 includes a conical shell 401 and a plurality of equally spaced electric heating plates 402 installed on the inner wall of the conical shell 401.

[0026] It should be noted here that: the atomizer 8 sprays out the liquid mist, which blows on the conical shell 401. The conical shell 401 separates the liquid mist from the middle, making the liquid mist flow along the space between the conical shell 401 and the inner wall of the tank body 1. The electric heating plates 402 can heat the conical shell 401 and can heat and dry the mist droplets blowing on the surface of the conical shell 401.

[0027] In a preferred embodiment, the stirring assembly 5 includes a rotating shaft 501, a first stirring plate 502 and a second stirring plate 503 mounted on both sides of the outer wall of the rotating shaft 501, a plurality of arc-shaped plates 504 equidistantly distributed on the outer wall of the rotating shaft 501, and a scraping plate 505 fixed to the bottom of the outer wall of the rotating shaft 501.

[0028] It should be noted here that when the hot air flows in the hot air pipe 2, it will blow the arc-shaped plate 504, drive the rotating shaft 501 to rotate, and then drive the first stirring plate 502, the second stirring plate 503 and the scraping plate 505 to rotate. The rotation of the first stirring plate 502 and the second stirring plate 503 can stir the hot air flow and the liquid mist together, making the contact between the liquid mist and the hot air flow more sufficient.

[0029] In a preferred embodiment, the exhaust assembly 6 includes an exhaust pipe 601 and a filter screen 602 fixed to the bottom of the exhaust pipe 601.

[0030] It should be noted here that the air flow in the tank body 1 is discharged through the exhaust pipe 601. The provided filter screen 602 can filter the discharged air flow, avoiding taking away too much powder. At the same time, the rotation of the scraping plate 505 can scrape the bottom of the filter screen 602, facilitating the scraping off of the filtered powder and ensuring the filtering effect.

[0031] Working principle: The liquid material can be input into the atomizer 8 through the liquid supply pipe 9, and the liquid mist is sprayed out through the atomizer 8. At the same time, hot air is introduced into the hot air pipe 2. The hot air enters the vertical pipe 301 through the hot air pipe 2 and then enters the shunt pipe 302 and is sprayed out from the nozzle 303, blowing on the liquid mist for drying. The liquid mist sprayed out by the atomizer 8 blows on the conical shell 401. The conical shell 401 separates the liquid mist, making the liquid mist flow along the space between the conical shell 401 and the inner wall of the tank body 1, avoiding the situation that the droplets in the conical shape may be difficult to fully contact with the hot air, which affects the drying effect. The conical shell 401 can be heated by the electric heating plate 402, and the droplets blown on the surface of the conical shell 401 can be heated and dried.

[0032] The dried powder falls into the collection box 7. The gas in the tank body 1 is discharged through the exhaust pipe 601. The provided filter screen 602 can filter the discharged air flow, avoiding taking away too much powder. When the hot air flows in the hot air pipe 2, it will blow the arc-shaped plate 504, drive the rotating shaft 501 to rotate, and then drive the first stirring plate 502, the second stirring plate 503 and the scraping plate 505 to rotate. The rotation of the first stirring plate 502 and the second stirring plate 503 can stir the hot air flow and the liquid mist together, making the contact between the liquid mist and the hot air flow more sufficient. The rotation of the scraping plate 505 can scrape the bottom of the filter screen 602, facilitating the scraping off of the filtered powder and ensuring the filtering effect.
