[0020] In order to make the purpose, technical solution and advantages of the embodiments of the present utility model clearer, the technical solution of the present utility model will be clearly and completely described below in conjunction with the embodiments.

[0021] Example

[0022] like Figure 1 As shown, Figure 1 Shown is a schematic plan cross-sectional view of an aging tank in an embodiment.

[0023] The device comprises a tank body 1 having a reaction cavity, a partition 11, a feed port 21, a discharge port 22 and a cooling jacket 40; the partition 11 is arranged inside the tank body 1 to divide the reaction cavity into a plurality of independent sub-cavities; the discharge port 22 and the feed port 21 are both arranged through the side wall of the sub-cavity and the height of the discharge port 22 is higher than the height of the feed port 21; a plurality of cooling jackets 40 are correspondingly sleeved on the outer periphery of each sub-cavity, and cooling liquid is injected into the cooling jacket 40 to control the reaction temperature inside the sub-cavity.

[0024] The reaction chamber is divided into a plurality of sub-chambers by a partition 11 arranged inside the tank body 1. Specifically, in the present embodiment, three sub-chambers are arranged. These three sub-chambers can be used individually or in series to meet the process requirements of different products. For example, according to the material characteristics and the reaction time, one sub-chamber, two sub-chambers or three sub-chambers can be selected to carry out the reaction between the materials and control the reaction time.

[0025] Furthermore, by separately setting the feed port 21 and the discharge port 22 on each sub-cavity, the discharge port 22 of the corresponding sub-cavity can be selected to directly discharge the material according to the reaction time required for the material in each sub-cavity, thereby terminating the reaction.

[0026] Alternatively, multiple sub-cavities can be used in series to achieve material reaction: liquid material enters from the feed port 21 of the bottom terminal cavity, overflows from the discharge port 22 of the sub-cavity after reaction, and then is injected from the feed port 21 of the second-layer sub-cavity through an external auxiliary component (such as a pump body), and the cycle continues until the reacted material is discharged from the discharge port 22 of the top layer.

[0027] Specifically, the feed port 21 located in the lowermost sub-cavity is set at the lowest end of the layer, and the feed port 21 located in the uppermost sub-cavity is set at the highest end of the layer; the feed port 21 and the discharge port 22 of the middle layer are respectively set on the side wall of the layer near the bottom and the top.

[0028] The cooling jacket 40 realizes temperature control of the reaction inside the sub-cavity. The cooling jacket 40 separately arranged on the periphery of each sub-cavity can realize different temperature control for different sub-cavities to match the specific reaction inside the sub-cavity, thereby solving the problem of precise temperature control and realizing gradient heat exchange.

[0029] The cooling jacket 40 includes a liquid storage cavity, a liquid inlet 41 and a liquid outlet 42 disposed therein. The liquid inlet 41 and the liquid outlet 42 are disposed at two ends of the cooling jacket 40 , respectively. The liquid inlet 41 is disposed at a height higher than the liquid outlet 42 .

[0030] The cooling jacket 40 realizes temperature control by injecting liquids of different temperatures into the liquid storage chamber. The liquid is injected from the liquid inlet 41 and discharged from the liquid outlet 42 .

[0031] It also includes baffles 30, and multiple groups of baffles 30 are arranged inside the sub-cavity at intervals to form an S-shaped flow channel;

[0032] A plurality of baffles 30 are arranged in the sub-cavity to change the flow direction and speed of the fluid in each sub-cavity, thereby controlling the length of the reaction time and also making the reaction materials have a first-in-first-out effect.

[0033] like Figure 2As shown, Figure 2 What is shown is a schematic diagram of the baffle structure of the aging tank in the embodiment;

[0034] A storage cavity 31 is provided inside the baffle plate 30 , and one end of the baffle plate 30 connected to the side wall of the sub-cavity is connected to the liquid storage cavity of the cooling jacket 40 .

[0035] By setting a storage chamber 31 connected to the liquid storage chamber of the cooling jacket 40 inside the baffle 30, the liquid inside the liquid storage chamber of the cooling jacket 40 can further flow into the baffle 30, thereby increasing the contact area between the cooling liquid and the reaction material, and further increasing the efficiency of temperature control. The bottom wall of the storage chamber 31 is inclined to facilitate the discharge of the liquid.

[0036] Working principle: This device can use multiple sub-cavities in series to achieve material reaction: inject liquid material from the feed port 21 of the bottom terminal cavity, overflow from the discharge port 22 of the sub-cavity after reaction, and then inject the material from the feed port 21 of the second layer of sub-cavity through external auxiliary parts (such as a pump body), and circulate in this way until the reacted material is discharged from the discharge port 22 of the top layer. While the material reacts inside each layer of sub-cavity, according to the needs of the specific reaction, liquid of corresponding temperature can be injected into the corresponding cooling jacket 40 to achieve temperature control of the reaction inside the sub-cavity. In addition, according to the length of the reaction time required for the material in each sub-cavity, the discharge port 22 of the corresponding sub-cavity can be selected to directly discharge the material to end the reaction.

[0037] The above embodiments are only used to illustrate the technical solution of the present invention, but not to limit it.
