Description

Technical Field

[0001] This utility model relates to the field of spray drying technology, specifically a spray drying device that is easy to clean. Background Technology

[0002] Spray drying equipment is used to quickly dry liquid materials into powder or granular products. It is widely used in many industries such as food, pharmaceuticals, and chemicals. The working principle is to use an atomizer to disperse the liquid material into extremely fine mist droplets, increasing the contact area between the liquid and the drying medium. The mist droplets are then brought into full contact with the drying medium, such as hot air. During the heat exchange process, the moisture in the droplets evaporates rapidly. The drying medium is usually heated by an air heater and then sent into the drying chamber. The dried powder or granular product enters the collection device along with the drying medium. The inside of the equipment, especially the vertical part of the drying tower, cannot be completely cleaned from top to bottom. The upper vertical surface and the top inclined surface cannot be covered, and the residual material will affect the quality of the next batch of products. Manual scraping can easily damage the anti-stick coating on the inner wall, which requires high skill from the workers.

[0003] Chinese patent CN220213935U discloses a high-efficiency spray drying device, including a spray dryer body. A cover plate is installed on the upper surface of the spray dryer body. An electromechanical box is installed on the bottom surface of the spray dryer body. A motor is installed on the inner bottom wall of the electromechanical box. A bearing is embedded in the inner bottom wall of the spray dryer body. A rotating tube is fixedly connected to the inner ring of the bearing. The bottom end of the rotating tube is connected to the output end of the motor. Multiple air outlets are opened on the outer surface of the rotating tube. Two cleaning plates are fixedly connected to the outer surface of the rotating tube. A protective box is installed on the back of the spray dryer body. An air pump is installed inside the protective box. A conduit is fixedly connected to the output end of the air pump. The end of the conduit away from the protective box passes through the protective box and the cover plate and extends into the interior of the rotating tube. A sealing door is hinged to the outer surface of the spray dryer body. Multiple rectangular openings are opened on the outer surface of the conduit.

[0004] However, the technical solution of this patent has the following problems:

[0005] This patent does not allow for rapid cleaning of the inclined surface at the top and the upper sidewalls of the spray dryer.

[0006] Therefore, those skilled in the art have provided a spray drying device that is easy to clean in order to solve the above-mentioned problems. Utility Model Content

The unfolding plate stops rotating at 90 degrees. The support frame is used to assist in supporting the unfolding plate and keeping it stable. At this time, the output shaft of the second motor of the rotating mechanism of the stabilizing flipping device drives the third gear to rotate. The third gear drives the fourth gear to rotate. The fourth gear drives the slip ring to rotate. The slip ring drives the shaped rod to rotate. The shaped rod drives the nozzle to rotate. The external water spraying device delivers water to the shaped rod through the hose and slip ring, so that multiple nozzles on the shaped rod spray water at the same time to rinse the inclined surface of the top of the spray dryer, which is conducive to the rapid unfolding and rinsing of the inclined surface of the top of the spray dryer.

[0018] 2. After rinsing through the inclined surface at the top of the spray dryer, adjust the shaped rod to a horizontal position through the observation window of the spray dryer. The cylinder output end of the stabilizing tilting device extends, causing the L-shaped rotating plate to rotate clockwise on the rotating frame. When the cylinder reaches its maximum range, the L-shaped rotating plate stops rotating 90 degrees. At this time, the L-shaped rotating plate is fixed by the cylinder. The first motor of the cleaning device rotates, driving the second gear to rotate. The second gear rotates, driving the first gear to rotate. The first gear rotates, driving the fixed seat to rotate. Since the fixed seat is fixed on the extension device, the rotation of the first gear drives itself and the rotating frame to rotate around the central axis of the fixed seat. The rotation of the rotating frame drives the stabilizing tilting device to rotate. In conjunction with the shaped rod and the nozzle on it, the output end of the linear module moves up and down, repeatedly rinsing the side wall of the spray dryer. This facilitates the rapid unfolding of repeated rinsing of the side wall of the spray dryer. Attached Figure Description

The first gear 42 rotates, driving the fixed seat 41 to rotate. Since the fixed seat 41 is fixed on the extension device 3, the first gear 42 rotates, causing itself and the rotating frame 43 to rotate around the central axis of the fixed seat 41. The rotating frame 43 rotates, driving the stable flipping device to rotate.

[0032] The stabilizing and flipping device includes a cylinder 46, a fixing plate 47, and an L-shaped rotating plate 48.

The external water spraying device delivers water to the shaped rod 5 through the hose and slip ring 411, so that multiple nozzles 6 on the shaped rod 5 spray water simultaneously.

[0038] The irregular rod 5 has inclined surfaces at both ends, and multiple nozzles 6 are fixedly installed on the inclined surfaces, which is conducive to multi-angle spraying.

[0039] Example 2: In some embodiments, such as Figures 1-7 In a preferred embodiment of this utility model, the extension device 3 includes: a first vertical pipe 31, a gate valve 32, a second vertical pipe 33, a linear module 34, and an L-shaped extension frame 35.

The second vertical pipe 33 is fixedly installed at the end of the gate valve 32 away from the first vertical pipe 31. The linear module 34 is fixedly installed inside the second vertical pipe 33. The L-shaped extension frame 35 is fixedly installed at the output end of the linear module 34. The fixing seat 41 is fixedly installed on the L-shaped extension frame 35 of the extension device 3. The linear module 34 can be configured as a ball screw linear module 34.

[0040] like Figure 3 , Figure 4 As shown, the gate valve 32 of the extension device 3 opens, and the output end of the linear module 34 moves downward, causing the L-shaped extension frame 35 to move downward, in preparation for cleaning.

[0041] The extension device 3 further includes: an unfolding plate 36, a third motor 37, and a support frame 38. The unfolding plate 36 is rotatably connected to the side of the L-shaped extension frame 35 away from the output end of the linear module 34 via a rotating shaft.

The support frame 38 is fixedly installed on the right side of the L-shaped extension frame 35. The first motor 44, the second motor 49, and the third motor 37 are all configured as self-locking motors.

[0042] like Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 As shown, the output shaft of the third motor 37 rotates, driving the unfolding plate 36 to rotate. The unfolding plate 36 stops after rotating 90 degrees. The support frame 38 is used to assist in supporting the unfolding plate 36 to maintain its stable state. The unfolding is completed in one go.

The external water spraying device delivers water to the shaped rod 5 through the hose and slip ring 411, so that multiple nozzles 6 on the shaped rod 5 spray water simultaneously to rinse the inclined surface of the top of the spray dryer 1.

[0043] After the top inclined surface of the spray dryer 1 is rinsed, the irregular rod 5 is adjusted to a horizontal position through the observation window of the spray dryer 1. The output end of the cylinder 46 of the stabilizing flipping device extends, driving the L-shaped rotating plate 48 to rotate clockwise on the rotating frame 43. When the cylinder 46 reaches its maximum range, the L-shaped rotating plate 48 rotates 90 degrees and stops. At this time, the L-shaped rotating plate 48 is fixed by the cylinder 46 and unfolds again. The first motor 44 of the cleaning device 4 rotates, driving the second gear 45 to rotate. The second gear 45 rotates, driving the first gear 42 to rotate. The first gear 42 rotates, driving the fixed seat 41 to rotate. Since the fixed seat 41 is fixed on the extension device 3, the rotation of the first gear 42 drives itself and the rotating frame 43 to rotate around the central axis of the fixed seat 41. The rotation of the rotating frame 43 drives the stabilizing flipping device to rotate, cooperating with the irregular rod and the nozzle 6 on it. At the same time, the output end of the linear module 34 moves up and down, repeatedly rinsing the side wall of the spray dryer 1.
