Abstract
Description
Technical Field
[0001] This utility model relates to the field of pharmaceutical equipment technology, and in particular to a centrifugal pelleting closed sampling device. Background Technology
[0002] The working principle of the closed sampling device for pellet making is that during the operation of the pellet making machine, the sample is connected to the sampling port through a sealed pipe. With the help of a power device, the pellet sample inside the pellet making machine is extracted into a sealed sampling container according to the set amount and time interval. This ensures that the entire sampling process is isolated from the external environment. Its application scenarios are mainly concentrated in the pellet production workshops of pharmaceutical companies. Whether it is the large-scale production of traditional Chinese medicine pills or Western medicine pills, the closed sampling device for pellet making is an indispensable device.
[0003] A closed sampling device for pelleting typically consists of a sealed sampling port, a sampling pipeline, a power unit, a sampling container, and a lifting cylinder. The sealed sampling port connects to the pelleting machine, the sampling pipeline transports the pellets, the power unit provides sampling power, the sampling container collects the sample, and the lifting cylinder controls the sampling process. In quality control, when it is necessary to periodically test indicators such as the appearance and dimensional uniformity of the pellets, this device can efficiently and accurately obtain representative samples, ensuring product quality.
[0004] In existing technologies, some sampling devices only provide the function of conveying pills to the detection system to detect the appearance and size of the pills. However, this detection method is prone to causing wet particles to clog the pipes, which will affect subsequent detection. Therefore, a centrifugal pelleting closed sampling device is proposed to solve the above problems. Utility Model Content
[0005] To overcome the above shortcomings, this utility model provides a centrifugal pelleting closed sampling device, which aims to improve the problem that wet particles easily clog the pipeline in the prior art.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A centrifugal pelleting closed sampling device includes a pelleting chamber (1), characterized in that: a dispersing system for dispersing pellets is fixedly connected to the top of the pelleting chamber (1), a transmission pipe (2) is fixedly connected to the inner wall of the pelleting chamber (1), a hot air chamber (11) is fixedly connected to the outer wall of the transmission pipe (2), a hot air blower (3) is fixedly connected to the other end of the hot air chamber (11), a fixing sleeve (10) is fixedly connected to the outer wall of the transmission pipe (2), a cylinder (4) is fixedly connected to the bottom of the fixing sleeve (10), a suction machine (5) is fixedly connected to one end of the transmission pipe (2), and an industrial control computer (7) is fixedly connected to the top of the pelleting chamber (1).
[0008] As a further description of the above technical solution:
[0009] The bulk material system includes a fixed plate, which is fixedly connected to the top of the granulation chamber. The bulk material system includes a fixed plate (12), and an air blowing pipe (14) is fixedly connected inside the fixed plate (12).
[0010] As a further description of the above technical solution:
[0011] One end of the blowing pipe (14) is fixedly connected to an air pump (15), and the bottom of the air pump (15) is fixedly connected to the top of the granulation chamber (1).

[0020] This utility model has the following beneficial effects:
[0021] 1. In this utility model, when the suction machine is started, the pills at the bottom of the granulation chamber are sucked into the inside of the transmission pipe under the action of the suction machine. At this time, the hot air blower is started. When the pill particles are sucked into the inside of the hot air chamber, the hot air blown out by the hot air blower will dry the wet particles. In this way, the pill particles can be fully dried. By adding a hot air system, the wet particles are dried, and the problem of stable conveying of wet particles is solved. In the past, wet particles would block the pipes for a long time.
[0022] 2. In this utility model, when the pill particles are transported to the fixed plate, the air pump will start. The air pump will continuously blow air into the interior of the fixed plate through the air blowing pipe. When the pill particles are transported into the interior of the fixed plate, the pills will be continuously dispersed under the action of the airflow, preventing the pills from continuously accumulating inside the fixed plate and thus blocking the interior of the fixed plate.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0029] Reference Figures 1 to 3 This utility model provides an embodiment of a centrifugal pelleting and closed sampling device, including a pelleting chamber 1. The pelleting chamber 1 is an important structure in the entire device for accommodating related components and pellets. Its top is fixedly connected to a dispersing system for dispersing the pellets. The dispersing system is responsible for the reasonable dispersion of the pellets so that subsequent processing operations can be performed on the pellets better. A transmission pipe 2 is fixedly connected to the inner wall of the pelleting chamber 1. The transmission pipe 2 is used to transport the pellets. A hot air chamber 11 is fixedly connected to the outer wall of the transmission pipe 2. The hot air chamber 11 is located outside the transmission pipe 2, providing a corresponding space environment for the pellets to enter and undergo hot air drying treatment.
[0030] A hot air blower 3 is fixedly connected to the other end of the hot air chamber 11. The hot air blower 3 is the key equipment for generating hot air. When the device operates to the corresponding stage, the hot air blower 3 will start working to provide a source of hot air for drying the pill granules. A fixing sleeve 10 is fixedly connected to the outer wall of the transmission pipe 2. The fixing sleeve 10 plays the role of assisting in fixing the transmission pipe 2. A cylinder 4 is fixedly connected to the bottom of the fixing sleeve 10. The cylinder 4 can drive the fixing sleeve 10 to change its height through its own extension and retraction movement. The fixing sleeve 10 drives the pipe to move upward, thereby realizing sampling. When sampling is needed, the cylinder 4 rod retracts. When not sampling, the cylinder 4 rod extends to avoid the sampling pipe causing breakage or other effects on the pills inside the granulation chamber 1.
[0031] One end of the transmission pipe 2 is fixedly connected to a suction machine 5. The suction machine 5 is the starting component for sucking up the pills. During operation, the suction machine 5 and the heater are turned on first, and the cylinder 4 rod is retracted so that the sampling pipe end is buried inside the material in the granulation chamber 1. Under the suction force generated by the suction machine 5, the pills at the bottom of the granulation chamber 1 will be sucked into the transmission pipe 2. The top of the granulation chamber 1 is fixedly connected to an industrial control computer 7. The industrial control computer 7 is the control core of the entire device. It can coordinate the various components to work in an orderly manner according to the pre-set programs and instructions to ensure the normal operation of the entire sampling device.
[0032] The inner wall of the granulation chamber 1 is fixedly connected to a particle return pipe 8. The particle return pipe 8 allows the pellets, after a series of processing and testing procedures, to return to the granulation chamber 1, realizing the circulation of the pellets within the device. The bottom of the hot air chamber 11 is fixedly connected to the bottom of the granulation chamber 1. This connection method ensures the stable installation of the hot air chamber 11 on the granulation chamber 1, enabling it to stably cooperate with the entire device to complete the drying work related to the pellets. The outer wall of the industrial control computer 7 is fixedly connected to a wire 9. The other end of the wire 9 is fixedly connected to the inner wall of the online particle size analyzer 6. The wire 9 is responsible for establishing a connection between the industrial control computer 7 and the online particle size analyzer 6, ensuring that signals can be transmitted smoothly between the two, so that the online particle size analyzer 6 can normally receive the instructions of the industrial control computer 7 and carry out particle size detection work on the pellets.
[0033] Reference Figures 1 to 3The outer wall of the fixed plate 12 is fixedly connected to the conveying pipe 13. The upper half of the conveying pipe 13 is open. This open structure allows the external online particle size detector 6 to smoothly detect the particle size of the pills when they pass through the conveying pipe 13 without being obstructed. The outer wall of the fixed sleeve 10 is fixedly connected to the top of the cylinder 4. When the cylinder 4 moves, it ensures that the fixed sleeve 10 and other connected components can stably move and change accordingly with the movement of the cylinder 4. The inside of the fixed plate 12 is fixedly connected to the air blowing pipe 14. Air is blown out through the air blowing pipe 14 to disperse the pills inside the fixed plate 12. One end of the air blowing pipe 14 is fixedly connected to the air pump 15. The air pump 15 is used to provide a continuous supply of gas to the air blowing pipe 14. The bottom of the air pump 15 is fixedly connected to the top of the granulation chamber 1, which makes it easy to fix the air pump 15 on the surface of the granulation chamber 1.
[0034] Working principle: The material embedded in the granulation chamber 1 is lifted by the cylinder 4 through the transmission pipe 2. The pills at the bottom of the granulation chamber 1 are sucked into the transmission pipe 2 by the suction machine 5. When the pills are sucked into the hot air chamber 11 and the subsequent conveying pipe 13 by the hot air blown ...
[0035] When the pill particles are conveyed to the fixed plate 12, the air pump 15 will start. The air pump 15 will continuously blow air into the interior of the fixed plate 12 through the air blowing pipe 14. When the pill particles are conveyed into the fixed plate 12, the pills will be continuously dispersed under the action of the airflow, preventing the pills from accumulating inside the fixed plate 12 and thus blocking it. The surface of the conveying pipe 13 is semi-open. This openness facilitates the online particle size detection machine 6 to detect the particle size of the pills. After detection, the pills will re-enter the granulation chamber 1 through the particle return pipe 8.
[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
