[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] like Figure 1-5 As shown, a detachable cooling structure of a mixing chamber of an internal mixer comprises a cooling water bin 1; a partition frame 11 is fixedly connected to the middle of the cooling water bin 1; three groups of liquid transfer holes 12 are opened in the middle of the partition frame 11; a cover plate 13 is fixedly connected to the end of the cooling water bin 1; a liquid inlet 14 is fixedly connected to the middle of the cover plate 13; the liquid inlet 14 and the cover plate 13 are connected; two groups of slots 15 are opened in the middle of the cooling water bin 1; two groups of slots 15 are fixedly connected to the bottom of the cover plate 13; a sealing plate 16 is fixedly connected to the bottom of the cover plate 13; the middle part of the sealing plate 16 is gradually thickened; a plurality of groups of cushions 17 are fixedly connected to the middle of the sealing plate 16; when working, the staff needs to install the cooling water bin 1 and the middle cooling pipe of the internal mixer together, and then the staff needs to connect the liquid inlet 14 with the external water pipe, and open the valve to fill water into the cooling water bin 1. After the coolant passes through the partition frame 11 and the middle of the liquid transfer hole 12, it cools the cooling pipe and gradually approaches the drain port at the top of the partition frame 11 and is left out. By arranging a sealing plate 16 at the bottom of the partition frame 11, when the partition frame 11 and the cooling water bin 1 are fixed and closed by bolts, the sealing plate 16 will be stuck in the middle of the slot 15. Because the top of the sealing plate 16 is thicker than the bottom of the sealing plate 16, and with multiple groups of soft pads 17, the sealing plate 16 and the soft pad 17 are gradually firmly stuck in the middle of the slot 15. This step can improve the sealing performance of the cover plate 13 and the sealing plate 16 when closed, reduce the phenomenon that part of the coolant will be discharged to the outside along the connection between the cover plate 13 and the cooling water bin 1 when the staff injects the external coolant into the cooling water bin 1, improve the cooling stability of the cooling pipe at the bottom of the cooling water bin 1, and reduce the problem of waste of primary coolant materials.

[0024] like Figure 2 and 5 As shown, a groove 2 is provided in the middle of the partition frame 11; a rotating shaft 21 is rotatably connected in the middle of the partition frame 11; a plurality of groups of blades 22 are fixedly connected in the middle of the rotating shaft 21; the blades 22 are arranged in a circular array in the middle of the rotating shaft 21; a conduit 23 is fixedly connected to the ends of the two groups of liquid transfer holes 12; the end of the conduit 23 is arranged near the blades 22; during operation, the blades 22 are arranged in the middle of the partition frame 11, and then the external coolant is injected into the cooling water tank 1. When the coolant in the first area is full, part of the coolant flows into the middle of the conduit 23 along the liquid transfer hole 12, and squeezes the blades 22 during the flow process, so that the blades 22 rotate in the middle of the partition frame 11. This step can cooperate with the force of the rotation of the blades 22 to mix the coolant temperature in the cooling water tank 1, reduce the problem that the coolant temperature at the bottom of the cooling water tank 1 is higher than the coolant temperature at the top after a long period of operation, and improve the uniformity of the coolant temperature in the cooling water tank 1 during operation.

[0025] like Figure 5 As shown, the end of the fan blade 22 is provided with a guide port 3; the guide port 3 and the fan blade 22 are fixedly connected; when working, by providing the guide port 3 at the end of the conduit 23, the coolant will pass through the conduit 23 and the guide port 3 in sequence and push the fan blade 22. This step can reduce the end of the conduit 23, thereby increasing the flow rate of the coolant, improving the speed of the fan blade 22 when rotating in the middle of the partition frame 11, and accelerating the mixing of the coolant temperature inside the cooling water tank 1.

[0026] like Figure 5 As shown, a scraper 4 is fixedly connected to the end of the fan blade 22; the scraper 4 is fitted on the inside of the groove 2; when working, a guide port 3 is provided at the end of the fan blade 22, so that the scraper 4 can clean the inside of the groove 2 when the fan blade 22 rotates. This step can improve the cleanliness of the inner wall of the groove 2 and reduce the trouble of the staff in cleaning the inner wall of the groove 2.

[0027] like Figure 1 As shown, a friction pad 5 is fixedly connected to the bottom of the cooling water bin 1; the friction pad 5 is arranged in two groups at the bottom of the groove 2; when working, by arranging two groups of friction pads 5 at the bottom of the cooling water bin 1, the friction pad 5 is stuck on the cooling pipe and the middle part of the cooling water bin 1. This step can reduce the wear of the cooling water bin 1 and the cooling pipe over time and increase the adaptability life of the cooling water bin 1.

[0028] like Figure 1 and 2As shown, a filter screen 6 is provided in the middle of the liquid inlet 14; the filter screen 6 is fixedly connected to the liquid inlet 14; during operation, the filter screen 6 is provided at the end of the liquid inlet 14, so that the filter screen 6 filters the impurities in the coolant. This step can reduce the precipitation of impurities in the coolant inside the cooling water bin 1, and reduce the period of staff cleaning the inside of the cooling water bin 1.

[0029] like Figure 5 As shown, the end of the fan blade 22 is set in an arc shape; when working, by setting the end of the fan blade 22 in an arc shape, this step can reduce the resistance of the fan blade 22 after being blown by the coolant, and further improve the stability of the fan blade 22 when rotating.

[0030] Working principle: by installing the cooling water tank 1 and the cooling pipe in the middle of the internal mixer together, the staff needs to connect the liquid inlet 14 to the external water pipe, and then open the valve to inject water into the cooling water tank 1, so that the coolant passes through the middle of the partition frame 11 and the liquid transfer hole 12 and cools the cooling pipe, and at the same time, it will gradually approach the drain port at the top of the partition frame 11 and leave it out. By providing a sealing plate 16 at the bottom of the partition frame 11, when the partition frame 11 and the cooling water tank 1 are fixed and closed by bolts, the sealing plate 16 will be stuck in the middle of the slot 15. Because the top of the sealing plate 16 is thicker than the bottom of the sealing plate 16, and with multiple sets of soft pads 17, the sealing plate 16 and the soft pad 17 are gradually firmly stuck in the middle of the slot 15. By providing a fan blade in the middle of the partition frame 11 22, and then after the external coolant is injected into the cooling water tank 1, when the coolant in the first area is full, part of the coolant flows into the middle of the conduit 23 along the liquid transfer hole 12, and squeezes the fan blades 22 during the flow process, so that the fan blades 22 rotate in the middle of the partition frame 11, and a guide port 3 is provided at the end of the conduit 23, so that the coolant will pass through the conduit 23 and the guide port 3 in turn and push the fan blades 22, and a guide port 3 is provided at the end of the fan blade 22, so that the scraper 4 of the fan blade 22 cleans the inside of the groove 2 when the fan blade 22 rotates, and two groups of friction pads 5 are provided at the bottom of the cooling water tank 1, so that the friction pads 5 are stuck on the cooling pipe and the middle of the cooling water tank 1, and a filter screen 6 is provided at the end of the liquid inlet 14, so that the filter screen 6 filters impurities in the coolant.
