Description

Technical Field

[0001] The utility model belongs to the technical field of pharmaceutical equipment, and particularly relates to a pot body of a wet granulator. Background Art

[0002] In the wet granulation process of drugs, the stability of materials and binders affects the granulation effect; the different boiling points, freezing points and temperature sensitivities of materials and binders affect the stability of materials and binders. The wet granulator uses a single-layer stainless steel pot body, which cannot meet the temperature control requirements of materials during the wet granulation process. The Chinese patent solution with the publication number CN213886084U discloses a coiled pipe type wet granulator sandwich temperature control pot body, which adjusts the temperature through the temperature control medium in the coiled pipe, and then transfers the temperature to the inside of the pot body through the temperature control medium in the temperature control layer. It has the disadvantages of complex structure, high processing and manufacturing cost, slow temperature control adjustment process and low heat conduction speed. The Chinese patent solution with the publication number CN205253045U discloses a jacket temperature control device for a wet granulator, which realizes the heating and temperature control of the materials in the pot body through a sealed double-layer design, with an external heat preservation layer for heat preservation and heating oil introduced into the internal oil heating layer.

A plurality of partition plates 10 are provided in the second interlayer 6. The partition plates 10 are used to divide the second interlayer 6 into multiple regions. A second channel 11 for communicating the multiple regions in the second interlayer 6 with each other is provided on the partition plates 10.

[0025] The first interlayer 5 and the second interlayer 6 are respectively provided on the side wall and the bottom wall of the chamber 100. The first interlayer 5 and the second interlayer 6 are respectively manufactured and processed, which is convenient for processing and manufacturing. A plurality of partition plates 10 are provided in the second interlayer 6. The strength of the bottom wall is enhanced through the partition plates 10, and then the strength of the entire pot body is enhanced, making the pot body not easily damaged. A heat exchange medium inlet 8 and a heat exchange medium outlet 7 are provided on the first interlayer 5 and the second interlayer 6 to realize the inlet and outlet of the heat exchange medium. Since the first interlayer 5 and the second interlayer 6 are only separated from the chamber 100 by one layer of side wall and bottom wall, the heat conduction of the heat exchange medium is faster, and the temperature can be quickly regulated. A second channel 11 for communicating the multiple regions in the second interlayer 6 with each other is provided on the partition plates 10. After the heat exchange medium enters the second interlayer 6, it flows to both sides through the second channel 11. Due to the blockage of the partition plates 10, the heat exchange medium stays in the second interlayer 6 for a longer time, and the temperature change around the bottom wall is more uniform during the temperature regulation process.

[0026] The side wall of the cavity 100 includes a first side wall 1 and a second side wall 2. The bottom wall of the cavity 100 includes a first bottom wall 3 and a second bottom wall 4. A first interlayer 5 is provided between the first side wall 1 and the second side wall 2, and a second interlayer 6 is provided between the first bottom wall 3 and the second bottom wall 4. The first interlayer communicates with the heat exchange medium outlet 7, and the second interlayer communicates with the heat exchange medium inlet 8. A first channel 9 is provided on the first bottom wall 3. The first channel 9 communicates the first interlayer 5 and the second interlayer 6.

The heat exchange medium enters from the bottom and exits from the top, achieving full heat exchange. The plurality of partition plates 10 arranged up and down support the first bottom wall 3 and the second bottom wall 4, playing a strengthening role.

[0028] One side of the partition plate 10 is fixedly welded to the first bottom wall 3, and the other side of the partition plate 10 is plug-welded to the second bottom wall 4. First, a second channel 11 is machined on the partition plate 10, and the partition plate 10 is welded to the first bottom wall 3. Then, a hole is opened on the second bottom wall 4, and the second bottom wall 4 and the partition plate 10 are plug-welded through the hole opened on the second bottom wall 4. The partition plate 10 and the second bottom wall 4 are directly welded at the lower end of the first bottom wall 3, reducing the processing difficulty.

Through the third channel 16, the heat exchange medium enters the first sandwich layer 5, so that the temperature of the cutter holder is kept consistent with the temperature of the cavity. When the cutter holder is overheated, the heat exchange medium can cool the cutter holder to prevent the overheating of the cutter holder from affecting the characteristics of the processed materials.

[0030] A pot body rib 17 is provided between the first side wall 1 and the second side wall 2. The pot body rib 17 is welded between the first side wall 1 and the second side wall 2, increasing the connection position between the first side wall 1 and the second side wall 2 and strengthening the strength of the cavity 100.

[0031] A temperature sensor 18 is provided on the side wall of the cavity 100. The temperature sensor 18 includes a first sensor for detecting the temperature of the first sandwich layer 5 and a second sensor for detecting the temperature inside the pot body. Through the temperatures detected by the two sensors, the inflow and outflow rates of the heat exchange medium are adjusted in real time, and the temperature of the heat exchange medium can be adjusted to meet the granulation requirements.

A pot mouth flange 19 and a pot mouth snap flange 20 are provided at the top of the first side wall 1, facilitating the docking with the pot lid. A material discharge port 26 is arranged through the first side wall and the second side wall. By arranging the material discharge port 26 to discharge materials from below, the discharging is more convenient.

A bottom rib plate 25 is provided between the third bottom wall 24 and the second bottom wall 4 to strengthen the strength of the pot body by the bottom rib plate 25. The pot body is connected to the pot bottom flange 21 through the third bottom 24, which is convenient for mounting the pot body on the frame. And the first side wall 1 and the third bottom wall 24 are connected through the pot body conical surface 22, so that the second interlayer 6 is suspended above the third bottom wall 24, avoiding directly placing the second bottom wall 4 on the frame, which is beneficial to the heat exchange medium inlet 8 being arranged on the second bottom wall 4 and convenient for processing. Moreover, the pot body conical surface 22 makes the overall appearance of the pot body more beautiful.

[0034] The second channels 11 on adjacent partition plates 10 are arranged staggeredly, so that when the heat exchange medium passes through multiple areas of the second interlayer 6, the flowing path is longer, and during the temperature adjustment process, the temperature is more uniform.

[0035] A first channel 9 is provided on the first bottom wall 3. The first channel 9 communicates the first interlayer 5 and the second interlayer 6. The first channel 9 is a plurality of through holes arranged along the circumference of the first bottom wall 3. The through holes are convenient for processing. After processing the through holes on the first bottom wall 3, it can be welded to the first side wall 1. The heat exchange medium overflows upward from the plurality of through holes into the second interlayer 6 and then into the first interlayer 5 and overflows upward from the circumferential side. During the temperature adjustment process, the temperature uniformity in the first interlayer 5 is better.
