Description

Technical Field

[0001] The utility model belongs to the technical field of medicine making equipment, in particular to a dehydration device for preparing anhydrous ampicillin. Background Art

[0002] Ampicillin is a white crystalline powder with a slightly bitter taste. It is soluble in dilute acid and dilute alkali, slightly soluble in water, and almost insoluble in chloroform, 96% ethanol, ether and fixed oil. Anhydrous ampicillin is the dehydration product of ampicillin. Anhydrous ampicillin is usually heated to break the connection between the three molecules of crystal water in ampicillin and the main structure. In order to improve the uniform heating of ampicillin, the existing equipment uses a spiral tube to dehydrate the ampicillin slurry. Since the temperature is maintained at a high level of 80-85℃ for a long time, the inner wall of the spiral tube is inevitably adhered to the dehydration product of ampicillin, which reduces the output of anhydrous ampicillin.

[0003] After searching, for example (authorization announcement number CN218853481U) a dehydration device for preparing anhydrous ampicillin includes a spiral tube reactor, the main body of the spiral tube reactor is a double-layer spiral tube structure, the upper end of the inner layer of the spiral tube is the feed port, and the lower end of the inner layer is the discharge port; the lower end of the outer layer of the spiral tube is the water inlet, and the upper end of the outer layer is the water outlet; when dehydrating, hot water at 80-85°C is injected into the outer layer, and the ampicillin slurry to be dehydrated is injected into the inner layer; an insulation layer is arranged on the outer wall of the spiral tube. This device solves the problem of uneven heating when dehydrating ampicillin, but the device cannot clean the product adhering to the inner wall of the spiral tube, resulting in a reduction in production.

[0023] In the following description, a large number of specific details are given to provide a more thorough understanding of the utility model.

In other examples, in order to avoid confusion with the utility model, some technical features known in the art are not described.

[0024] Unless otherwise defined, the directions of up, down, left, right, front, back, inside and outside involved in this document are based on the directions of up, down, left, right, front, back, inside and outside in the figures shown in the present utility model, and are explained here together.

[0025] The connection method can be bonding, welding, bolt connection, etc., depending on actual needs.

[0026] Example

[0027] like Figures 1 to 4 As shown,

[0028] This embodiment includes:

[0029] A column 1 for preparing anhydrous ampicillin has a large-diameter base 4 welded at the bottom of the column 1. The diameter of the base 4 is much larger than the diameter of the column 1. The increase in the area of ​​the base 4 makes the column 1 fixed on the top of the base 4 more stable, which helps to increase the service life of the device.

[0030] The interior of the column 1 is provided with a cavity groove 6 for filling with high-temperature water of 80-85 degrees Celsius. The top of the cavity groove 6 is connected to a filling port 5. The top of the filling port 5 is provided with a sealing cover. The sealing cover can prevent dust in the air from entering the interior of the column 1, and can accurately adjust the temperature of the high-temperature hot water inside the cavity groove 6 through the filling port 5, so that the prepared anhydrous ampicillin is in the best production environment, thereby improving the preparation efficiency of the device.

[0031] A dehydration pipe 7 is provided inside the cavity tank 6 for dehydrating ampicillin. One end of the dehydration pipe 7 is connected to the feed pipe 9. A control valve for control is provided inside the feed pipe 9. The other end of the dehydration pipe 7 is connected to the discharge pipe 2. An electromagnetic valve is provided on the peripheral side of the discharge pipe 2. Through the arrangement of the feed pipe 9 and the discharge pipe 2, the prepared anhydrous ampicillin can be flexibly collected and stored. Because only the three molecules of water contained in the ampicillin can be separated from the main structure by heating, the ampicillin blades will be diluted and connected to the discharge pipe 2 through the water absorption device to complete the preparation of anhydrous ampicillin.

[0032] A rotatably connected rotating shaft 10 is provided inside the dehydration tube 7, one end of the rotating shaft 10 is rotatably connected to the inner bottom wall of the column 1, and the other end of the rotating shaft 10 passes through the end of the dehydration tube 7 and extends to the inside of the cavity groove 6. The bottom screw of the column 1 is connected to a driving motor 4 that provides power, and the output shaft of the driving motor 4 passes through the top wall of the column 1 and is connected to the rotating shaft 10 inside the cavity groove 6. The outer peripheral side of the rotating shaft 10 is connected to a spirally shaped paddle 11 that is slidably connected to the inner wall of the dehydration tube 7. By controlling the rotation of the driving motor 4, the rotating shaft 10 is driven to rotate inside the dehydration tube 7, and the driving connected spiral paddle 11 rotates to clean the product adhering to the inner wall of the dehydration tube 7, thereby avoiding material loss during the preparation of ampicillin and increasing the yield.

[0033] In order to facilitate maintaining the temperature inside the cavity groove 6, a corrosion-resistant and high-thermal conductivity heat-conducting plate is set on the inner wall of the column 1, and an electromagnetic induction or resistance electric heating plate 8 is embedded in the inner wall of the column 1. By controlling the high-temperature hot water in the electric heating plate 8 and the cavity groove 6, the ampicillin inside the dehydration tube 7 is heated evenly and the temperature difference is balanced, thereby improving the processing efficiency.

[0034] The setting of the paddle 11 is similar to the structure of an auger, but since there is a certain gap between the paddle 11 and the inner wall of the dehydration tube 7, which is sufficient for the flow of ampicillin, the output shaft of the drive motor 4 is controlled to rotate, driving the paddle 11 to rotate, in order to regularly stir the ampicillin inside the dehydration tube 7 and clean up the ampicillin product in which three water molecules are broken by high temperature.

[0035] The driving motor 4 is a conventional instrument, and its working principle, size and model are irrelevant to the function of the present application, so no further description is given. The control method of the present invention is controlled by a controller, and the control circuit of the controller can be realized by simple programming by technicians in this field. The provision of power is also common knowledge in this field, and the present invention is mainly used to protect mechanical devices, so the present invention will no longer explain the control method and circuit connection in detail.

[0036] How it works

[0037] The dehydration device for preparing anhydrous ampicillin, when using the device, firstly, high-temperature hot water of 80-85 degrees Celsius is added to the cavity groove 6 through the filling port 5, and the filling port 5 is sealed by the sealing cover, and then the pipeline with the ampicillin slurry flowing is connected to the feed pipe 9, and the output shaft of the driving motor 4 is started to rotate, so as to drive the connected rotating shaft 10 to rotate inside the dehydration tube 7, and the paddles 11 arranged on the side of the rotating shaft 10 rotate to clean the products adhering to the inner wall of the dehydration tube 7, and the electric heating plate 8 is started to work synchronously, so that the temperature inside the column 1 is always kept balanced, and finally, the ampicillin slurry is transported to the inside of the dehydration device through the discharge pipe 2 to complete the preparation of anhydrous ampicillin.
