Description

Technical Field

[0001] This utility model relates to the field of pharmaceutical equipment, specifically to an energy-saving drying device for pharmaceutical use. Background Technology

[0002] Conventional pharmaceutical processes typically involve weighing, mixing, granulation, fluidized bed drying, sizing, mixing, and tableting, followed by dispensing and packaging. Fluidized bed drying, as a crucial step, improves the quality and stability of pharmaceuticals and enhances drug performance. It is commonly used to process granular, powdered, or fibrous materials. By adjusting parameters such as temperature, humidity, and airflow, the drying requirements of different materials can be met. Existing fluidized bed dryers primarily use heated air to blow onto the material for drying. However, materials tend to accumulate during the drying process and do not make sufficient contact with the hot air. To ensure drying effectiveness, prolonged drying times are usually required, resulting in high energy consumption and low overall drying efficiency. Utility Model Content

Detailed Implementation

[0027] This section will describe in detail the specific embodiments of the present invention. Preferred embodiments of the present invention are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present invention, but they should not be construed as limiting the scope of protection of the present invention.

[0028] Example 1:

[0029] Reference Figures 1 to 8This utility model provides an energy-saving pharmaceutical drying equipment, including a frame 1 and a movable frame 2 with rollers. An upper cylinder 3 and a lifting mechanism 11 are mounted on the frame 1. An air outlet pipe 31 is connected to the upper cylinder 3. A middle cylinder 4 is movably mounted on the movable frame 2. A lower cylinder 5 is movably mounted on the frame 1. The lifting mechanism 11 drives the lower cylinder 5 to move so that the middle cylinder 4 is pressed against the bottom of the upper cylinder 3. A hot air pipe 51 is connected to the lower cylinder 5. A material placement net 41 is mounted on the middle cylinder 4. A heating chamber 52 is mounted on the hot air pipe 51. A heating device is installed inside the heating box 52. An air inlet pipe 53 is connected to the heating box 52. A heat exchange component 6 connected to the air outlet pipe 31 is installed on the air inlet pipe 53. A fan 54 is installed on the air inlet pipe 53. A rotating drum 7 is rotatably installed on the middle cylinder 4. Several turning frames 71 for turning materials are rotatably installed on the rotating drum 7. A drive mechanism 8 and a transmission component 9 are installed on the middle cylinder 4. The drive mechanism 8 is connected to the rotating drum 7 and drives the rotating drum 7 to rotate. The transmission component 9 is connected to the several turning frames 71 and drives the several turning frames 71 to rotate in coordination with the rotation process of the rotating drum 7.

[0030] The lower cylinder 5 is driven by the lifting mechanism 11 to lift the middle cylinder 4 and press it against the bottom of the upper cylinder 3, thus realizing the installation between the lower cylinder 5, the middle cylinder 4 and the upper cylinder 3. When the lower cylinder 5 is driven by the lifting mechanism 11 to descend, the middle cylinder 4 descends with the lower cylinder 5 under the action of gravity and detaches from the upper cylinder 3, thus realizing the detachable installation between the upper cylinder 3, the middle cylinder 4 and the lower cylinder 5, which makes it convenient to pull out the movable frame 2 to load and unload the middle cylinder 4.

[0031] After the upper cylinder 3, middle cylinder 4 and lower cylinder 5 are connected, the fan 54 drives air into the heating box 52. After the air is heated by the heating device, hot air is generated. The hot air dries the material on the mesh 41 placed in the middle cylinder 4. Through the drive mechanism 8 and the transmission component 9, several turning frames 71 are driven to rotate and turn simultaneously, fully turning the material so that the material can fully contact the hot air, which improves the drying efficiency. Then the hot air flows through the air outlet pipe 31 to the heat exchange component 6 to preheat the air at the air inlet pipe 53, which improves the heat energy utilization rate and saves energy.

[0032] Example 2:

[0033] Reference Figures 1 to 8 In conjunction with the technical solution of Embodiment 1, in this embodiment, a mounting platform 42 is provided on the middle cylinder 4, the rotating drum 7 is rotatably mounted on the mounting platform 42, and the driving mechanism 8 is a servo motor, which is connected to the rotating drum 7 and drives the rotating drum 7 to rotate.

[0034] The servo motor drives the rotating drum 7 to rotate relative to the mounting platform 42, which in turn drives several flipping frames 71 to rotate, and in conjunction with the transmission component 9, drives several flipping frames 71 to rotate on their own.

[0035] Furthermore, the transmission assembly 9 includes a central bevel gear 91 and a transmission bevel gear 92. The central bevel gear 91 is mounted on the mounting platform 42, and each flipping frame 71 is equipped with a transmission bevel gear 92. Several transmission bevel gears 92 mesh with the central bevel gear 91.

[0036] The servo motor drives the rotating drum 7 to rotate relative to the mounting platform 42. The rotation drives several turning frames 71 to rotate. During the rotation of the turning frames 71, the transmission bevel gear 92 on the turning frames 71 rotates around the central bevel gear 91 and rotates on its own axis under the action of the central bevel gear 91. This realizes the rotation and rotation process of several turning frames 71, which can fully turn the material and drive the material to fully contact the hot air, thus improving the drying efficiency.

[0037] Specifically, the turning frame 71 is equipped with several actuating levers 711 for turning materials.

[0038] The material is continuously turned over by several material-turning rods as the turning frame 71 rotates and revolves, which helps to drive the material to fully contact the hot air and improve the drying efficiency.

[0039] Example 3:

[0040] Reference Figures 1 to 8 In conjunction with the technical solutions of Embodiments 1 and 2, in this embodiment, the heat exchange component 6 includes a heat exchange box 61 and a heat conduction pipe 62. The heat conduction pipe 62 is disposed in the inner cavity of the heat exchange box 61. The air inlet pipe 53 is connected to the inner cavity of the heat exchange box 61. An air extraction pipe 611 is connected to the heat exchange box 61. One end of the heat conduction pipe 62 is connected to the air outlet pipe 31, and the other end of the heat conduction pipe 62 is connected to the exhaust pipe 621. The heat conduction pipe 62 has a spiral tubular structure.

[0041] The hotter air is discharged to the heat exchange box 61 through the air outlet pipe 31 at the upper cylinder 3, and flows through the heat conduction pipe 62. The spiral tubular structure of the heat conduction pipe 62 increases the contact area and contact time between the hot air inside and the outer periphery of the air inlet pipe 53, which helps to improve the heat exchange efficiency, fully preheat the air at the air inlet pipe 53, and save energy.

[0042] Specifically, rotating rods 43 are provided on both sides of the middle cylinder 4, and vertical slots 21 are provided on the movable frame 2 for the rotating rods 43 to be moved and installed. The rotating rods 43 can rotate relative to the vertical slots 21.

[0043] Through the structural cooperation between the rotating rod 43 and the vertical groove 21, the middle cylinder 4 can rotate and move vertically relative to the moving frame 2. When the lifting mechanism 11 drives the lower cylinder 5 to rise, it can push the middle cylinder 4 to move vertically and drive it to abut against the bottom of the upper cylinder 3, thereby realizing the installation between the lower cylinder 5, the middle cylinder 4 and the upper cylinder 3. After the installation between the upper cylinder 3, the middle cylinder 4 and the lower cylinder 5 is released, the middle cylinder 4 can be rotated and the material inside can be poured out, which facilitates the loading and unloading of the middle cylinder 4.

[0044] Specifically, a limiting frame 44 is provided on the outer side of the middle cylinder 4, and a limiting groove 441 is provided on the limiting frame 44. A sliding rod 22 is movably provided on the movable frame 2. The sliding rod 22 moves and inserts into the limiting groove 441 and abuts against the side wall of the limiting groove 441 to restrict the rotation of the middle cylinder 4. The sliding rod 22 can move vertically relative to the limiting groove 441.

[0045] The upper limit groove 441 of the limiting frame 44 cooperates with the slide rod 22. When the slide rod 22 is inserted into the limiting frame 44, the slide rod 22 abuts against the two side walls of the limiting groove 441 to restrict the rotation of the middle cylinder 4. At the same time, due to the structural action of the limiting rod and the vertical groove 21, the middle cylinder 4 can only maintain the upright state and move vertically relative to the moving frame 2. This facilitates the lower cylinder 5 to push the middle cylinder 4 to rise smoothly and abut against the upper cylinder 3, which can effectively prevent the material from accidentally spilling out of the middle cylinder 4. When it is necessary to spill the material, the slide rod 22 can be removed from the limiting groove 441 to release the limit. At this time, the middle cylinder 4 can be rotated at will to carry out the unloading work.

[0046] Specifically, the lifting mechanism 11 is a hydraulic cylinder.

[0047] The lower cylinder 5 is raised and lowered by a hydraulic cylinder, which in turn moves the middle cylinder 4 to enable detachable installation between the upper cylinder 3, the middle cylinder 4, and the lower cylinder 5.

[0048] Specifically, the heating device is an electric heating element.

[0049] The air is heated by an electric heating element to dry the material at the middle cylinder 4 in conjunction with the airflow guiding process of the fan 54.

[0050] Specifically, sealing rings are provided at the bottom of the upper cylinder 3 and the top of the lower cylinder 5.

[0051] The sealing rings at the bottom of the upper cylinder 3 and the bottom of the lower cylinder 5 fill the gaps between the upper cylinder 3, the middle cylinder 4 and the lower cylinder 5 to improve the sealing performance when the three are connected, prevent the drying efficiency from being reduced due to the leakage of hot air, and help maintain the overall drying effect.

[0052] The above description is merely a preferred embodiment of this utility model and does not constitute any limitation on this utility model. Any person skilled in the art can make many possible variations and modifications to the technical solution of this utility model, or modify it into equivalent embodiments, without departing from the scope of the technical solution of this utility model. Therefore, any modifications, equivalent changes, and alterations made to the above embodiments based on the technology of this utility model without departing from the scope of the technical solution of this utility model shall fall within the protection scope of this technical solution.
