DETAILED DESCRIPTION

[0023] The present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0024] like Figures 1 to 4As shown, a wet granulator pot body includes a cavity 100, a first interlayer 5 is provided on the side wall of the cavity 100, a second interlayer 6 is provided on the bottom wall of the cavity, the first interlayer 5 and the second interlayer 6 are connected, the first interlayer 5 and the second interlayer 6 are connected to a heat exchange medium inlet 8 and a heat exchange medium outlet 7, a plurality of partitions 10 are provided in the second interlayer 6, the partitions 10 are used to divide the second interlayer 6 into a plurality of areas, and a second channel 11 is provided on the partition 10 to connect the plurality of areas in the second interlayer 6 to each other.

[0025] A first interlayer 5 and a second interlayer 6 are respectively arranged on the side wall and the bottom wall of the chamber 100, and the first interlayer 5 and the second interlayer 6 are respectively manufactured and processed to facilitate processing and manufacturing. A plurality of partitions 10 are arranged in the second interlayer 6. The strength of the bottom wall is enhanced by the partition 10, and then the strength of the entire pot body is enhanced, so that the pot body is not easily damaged. A heat exchange medium inlet 8 and a heat exchange medium outlet 7 are arranged on the first interlayer 5 and the second interlayer 6 to realize the entry and exit of the heat exchange medium. Since the first interlayer 5 and the second interlayer 6 are separated from the chamber 100 by only one layer of side wall and bottom wall, the heat conduction of the heat exchange medium is faster and the temperature can be quickly adjusted. A second channel 11 is arranged on the partition 10 to interconnect multiple areas in the second interlayer 6. After the heat exchange medium enters the second interlayer 6, it flows to both sides through the second channel 11. Due to the obstruction of the partition 10, the heat exchange medium stays in the second interlayer 6 for a longer time, and the temperature change around the bottom wall during the temperature adjustment process is more uniform.

[0026] The side walls of the cavity 100 include a first side wall 1 and a second side wall 2, and 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 is connected to a heat exchange medium outlet 7, and the second interlayer is connected to a heat exchange medium inlet 8. A first channel 9 is provided on the first bottom wall 3, and the first channel 9 connects the first interlayer 5 and the second interlayer 6. A plurality of partitions 10 are connected between the first bottom wall 3 and the second bottom wall 4, and a second channel 11 is provided on the partition 10.

[0027] The heat exchange medium enters from the heat exchange medium inlet 8 at the bottom, fills the second interlayer 6 through the second channel 11, enters the first interlayer 5 through the first channel 9, and is output from the heat exchange medium outlet 7 at the top. The heat exchange medium enters from the bottom and exits from the top, and heat is fully exchanged. Multiple partitions 10 arranged above and below support the first bottom wall 3 and the second bottom wall 4 to play a reinforcing role.

[0028] One side of the partition 10 is welded and fixed to the first bottom wall 3, and the other side of the partition 10 is plug-welded and fixed to the second bottom wall 4. First, the second channel 11 is processed on the partition 10, and the partition 10 is welded to the first bottom wall 3, and then a hole is opened on the second bottom wall 4, and the second bottom wall 4 and the partition 10 are plug-welded through the hole opened on the second bottom wall 4, and the partition 10 and the second bottom wall 4 are directly welded at the lower end of the first bottom wall 3, which reduces the processing difficulty.

[0029] The invention also includes a cutter seat 12, which is penetrated on the side wall of the cavity 100. The cutter seat 12 includes a sleeve 13 and a surrounding edge 14 arranged on the outside of the sleeve 13. A third interlayer 15 is provided between the surrounding edge 14 and the sleeve 13. A third channel 16 is opened on the surrounding edge 14, and the third channel 16 is connected to the first interlayer 5. The surrounding edge 14 is welded on the side wall of the cavity 100. The heat exchange medium enters the first interlayer 5 through the third channel 16, so that the temperature of the cutter seat is consistent with the cavity temperature. When the cutter seat is overheated, the heat exchange medium can cool the cutter seat to prevent the overheating of the cutter seat from affecting the characteristics of the processed material.

[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 , thereby 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 interlayer 5 and a second sensor for detecting the temperature inside the pot body. The temperatures detected by the two sensors are used to adjust the inlet and outlet flow of the heat exchange medium in real time, and the temperature of the heat exchange medium can be adjusted to meet the granulation needs.

[0032] The first side wall 1 is welded and fixed to the top of the second side wall 2. A pot mouth flange 19 and a pot mouth buckle flange 20 are provided on the top of the first side wall 1 to facilitate docking with the pot cover. A discharge port 26 is penetrated through the first side wall and the second side wall. By setting the discharge port 26, materials are discharged from below, and the discharge is more planned. The first interlayer 5 can exchange heat with the discharge port 26, which is conducive to achieving stable discharge and reducing adhesion.

[0033] The third bottom wall 24 is provided with a pot bottom flange 21, and the third bottom wall 24 is connected to the first side wall 1 through a pot bottom lower conical surface 22. A stirring paddle mounting seat 23 is provided on the first bottom wall 3, the second bottom wall 4 and the third bottom wall 24. A bottom rib plate 25 is provided between the third bottom wall 24 and the second bottom wall 4. The strength of the pot body is strengthened by the bottom rib plate 25. The pot bottom flange 21 is connected through the third bottom 24, which is convenient for installing the pot body on the frame. The first side wall 1 and the third bottom wall 24 are connected through the pot body lower conical surface 22, so that the second interlayer 6 is suspended on the third bottom wall 24, avoiding placing the second bottom wall 4 directly on the frame, which is beneficial for the heat exchange medium inlet 8 to be arranged on the second bottom wall 4, which is convenient for processing, and the pot body lower conical surface 22 makes the overall appearance of the pot body more beautiful.

[0034] The second channels 11 on adjacent partitions 10 are arranged in a staggered manner, so that the heat exchange medium has a longer flow path when passing through multiple areas of the second interlayer 6, and the temperature is more uniform during the temperature adjustment process.

[0035] A first channel 9 is provided on the first bottom wall 3, and the first channel 9 connects 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 easy to process. After the through holes are processed in the first bottom wall 3, they can be welded to the first side wall 1. The heat exchange medium overflows the second interlayer 6 upward through the plurality of through holes, enters the first interlayer 5, and overflows upward from the peripheral side. During the temperature adjustment process, the temperature uniformity in the first interlayer 5 is better.

Any technician familiar with the art can make many possible changes and modifications to the technical solution of the present invention by using the technical content disclosed above without departing from the scope of the technical solution of the present invention, or modify it into an equivalent embodiment of equivalent changes.
