Abstract
Description
Technical Field
[0001] This utility model belongs to the field of dryer technology, specifically relating to a multi-functional spray dryer. Background Technology
[0002] A spray dryer is a continuous drying device that rapidly dries liquid or slurry materials into powder or granules through atomization and hot air contact. Its core advantages lie in efficient heat transfer, instantaneous drying within seconds, and controllable product flowability, making it widely used in food, pharmaceutical, chemical, and environmental protection industries.
[0003] Multifunctional spray dryers are a type of spray dryer that can adapt to different material characteristics such as heat sensitivity, high viscosity, and easy moisture absorption. However, they still have the problem that materials tend to adhere to the inner wall of the dryer, making them difficult to clean, or requiring unified cleaning after drying, which affects their use. Utility Model Content
[0004] To address the aforementioned problems, this utility model provides a multi-functional spray dryer that can effectively prevent materials from adhering to the inner wall, while also enabling effective cleaning during the process and regulating the temperature of the inner wall of the dryer.
[0005] To achieve the above objectives, this utility model provides a multi-functional spray dryer, including a machine body, an atomizer placed on the top of the machine body, a feed pipe and an air inlet pipe respectively connected to the atomizer, a discharge channel provided at the bottom of the machine body, a functional pipe provided inside the body wall, one end of the functional pipe being connected to an air inlet pipe with an air inlet fan, and the other end of the functional pipe being connected to an air outlet pipe with an air outlet fan, the functional pipe having functional zones, and rolling balls provided in the functional zones.
[0006] In some embodiments, the plurality of functional regions include a porous body with both ends and a spiral guide vane disposed inside the functional region.
[0007] In some embodiments, the spiral guide vane is connected to a porous body at both ends.
[0008] In some embodiments, the plurality of functional areas are provided with tapered tubes at both ends, and each tapered tube has an opening at both ends.
[0009] In some embodiments, the diameter of the rolling ball is larger than the diameter of the smallest opening of the tapered tube.

[0011] In some embodiments, the functional areas are arranged at equal intervals.
[0012] In some embodiments, the functional tube is at a certain distance from the inner wall of the body.
[0013] Beneficial effects:
[0014] This invention utilizes a functional tube and uses the incoming air as kinetic energy to drive the internal rolling ball to roll, thereby generating vibration on the inner wall of the machine. This effectively prevents materials from adhering to the inner wall. At the same time, the temperature inside the machine can be regulated by controlling the incoming air temperature.

[0021] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0022] The present invention will now be described in detail with reference to the specific embodiments shown in the accompanying drawings. However, these embodiments do not limit the present invention, and any structural, methodological, or functional modifications made by those skilled in the art based on these embodiments are included within the protection scope of the present invention.
[0023] like Figure 1The multi-functional spray dryer shown includes a body 1, an atomizer 2 located at the top of the body 1, a feed pipe 4 and an air inlet pipe 5 connected to the atomizer 2, and a discharge channel 3 at the bottom of the body 1. The discharge channel 3 is connected to a cyclone separator 11 via a pipe. The cyclone separator 11 can also be optionally connected to other equipment, such as a dust collector or a feeder. A functional tube 6 is provided inside the wall of the body 1. The functional tube 6 is at a certain distance from the inner wall surface of the body 1, that is, the outer wall surface of the functional tube 6 cannot be used as the inner wall surface of the body 1. One end of the functional tube 6 is connected to a... The air inlet pipe 9 of the air inlet fan 7 is connected, and the other end of the functional pipe 6 is connected to the air outlet pipe 10 equipped with the air outlet fan 8. The functional pipe 6 is provided with functional areas 61, and rolling balls 613 are provided in the functional areas 61. By utilizing the vibration generated by the rolling balls 613, the vibration of the inner wall surface of the machine body 1 is realized, thereby realizing the adhesion of materials to the inner wall surface. While the air entering by the air inlet fan 7 provides rolling kinetic energy to the rolling balls 613, the temperature of the incoming air can also be selected, thereby adjusting the internal temperature of the machine body 1. The functional areas 61 are arranged at equal intervals.
[0024] like Figure 2 The aforementioned functional areas 61 include porous bodies 611 with both ends and spiral guide vanes 612 disposed inside the functional areas 61. The spiral guide vanes 612 are connected to the porous bodies 611 at both ends. The porous bodies 611 can be screens, porous ceramic bodies, etc. Due to the spiral guide vanes 612, after the air enters, the spiral guide vanes 612 ensure that the rolling ball 613 rotates continuously, thereby generating vibration, which in turn drives the vibration of the inner wall of the machine body 1, thereby preventing the adhesion of materials.
[0025] like Figure 3 and Figure 4 The functional areas 61 shown are provided with tapered tubes 614 at both ends, each tapered tube 614 having an opening at both ends. The diameter of the rolling ball 613 is larger than the minimum opening diameter of the tapered tube 614. The structure of the tapered tubes 614 can effectively control the air intake speed, thereby ensuring the rolling ball's rotation within them. It is preferable that the two tapered tubes 614 are configured so that their minimum openings face the same direction, which ensures optimal rotation of the rolling ball 614.
[0026] like Figure 5 The functional tube 6 shown is in the shape of a spiral tube. The spiral tube can ensure effective uniform distribution of vibration on the entire body 1, and at the same time, it is beneficial to uniformly distribute vibration on the inner wall of the body 1.
[0027] Meanwhile, in this utility model, the inlet fan 7 and the outlet fan 8 can be converted into each other, that is, the inlet fan 7 can also be used as the outlet fan 8, and the outlet fan 8 can also be used as the inlet fan 7.
[0028] It should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
[0029] The detailed descriptions listed above are merely specific descriptions of feasible implementations of this utility model, and are not intended to limit the scope of protection of this utility model. All equivalent implementations or modifications made without departing from the spirit of this utility model should be included within the scope of protection of this utility model.
