[0028] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0029] As described in the background section, in practical applications, most existing heat exchangers have shorter heat exchange times due to the shorter tube length, which reduces the heat exchange efficiency when exchanging heat with chemical substances.

[0030] To solve this technical problem, this utility model provides a heat exchanger for chemical production, which is applied to chemical production.

[0031] For details, please refer to Figure 1 , Figure 2 A heat exchanger for chemical production specifically includes a tank body 1, a conveying mechanism 11 inside the tank body 1, a second outlet 5 at the lower end of the tank body 1, the second outlet 5 being connected to the tank body 1, a sealing mechanism 4 at the upper end of the tank body 1, a first filling port 2 at one side of the upper end of the tank body 1, the first filling port 2 being connected to the tank body 1, and a first outlet 3 at one side of the lower end of the tank body 1, the first outlet 3 being connected to the tank body 1.

[0032] The present invention provides a heat exchanger for chemical production. Through the structural design of the conveying mechanism 11 and the tank body 1, heat exchange can be carried out on the chemical substances in the tube bundle 10. The design of multiple baffles 16 allows the heat exchange water to enter from the first filling port 2 and pass through multiple baffles 16, so that the tube distance is longer when the distance to the tank body 1 is short, thereby increasing the heat exchange time and enhancing the heat exchange effect.

[0033] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0034] Example 1:

[0035] Please refer to Figures 1-3 A heat exchanger for chemical production includes a tank body 1, a conveying mechanism 11 inside the tank body 1, a second outlet 5 at the lower end of the tank body 1 connected to the tank body 1, a sealing mechanism 4 at the upper end of the tank body 1, a first filling port 2 at one side of the upper end of the tank body 1 connected to the tank body 1, and a first outlet 3 at one side of the lower end of the tank body 1 connected to the tank body 1.

[0036] Through the above structural design, it can be seen that by adding chemical substances into the conveying mechanism 11 through the sealing mechanism 4, the chemical substances are discharged from the second outlet 5 through the conveying mechanism 11. At the same time, by adding heat exchange water into the tank 1 from the first filling port 2, the chemical substances in the conveying mechanism 11 can be heat exchanged. Meanwhile, when the heat exchange water flows into the first outlet 3 through the conveying mechanism 11, the heat exchange water can be discharged through the first outlet 3. When it is necessary to clean the conveying mechanism 11, the sealing mechanism 4 can be used to release the seal on the tank 1 and the conveying mechanism 11 can be taken out from the inside of the tank 1 for cleaning.

[0037] Specifically, the conveying mechanism 11 includes a sealing disc 14, which is located at the upper end of the tank body 1. A second slot 12 is provided on the inner wall of the upper end of the tank body 1 at a position corresponding to the sealing disc 14. The sealing disc 14 is inserted into the second slot 12. A sealing strip 15 is fixedly connected to the periphery of the upper end of the sealing disc 14. The sealing strip 15 is tightly fitted to the inner wall of the tank body 1. Multiple first holes are provided at the end of the sealing disc 14. A tube bundle 10 is fixedly connected to each of the multiple first holes.

[0038] Furthermore, a sealing seat 17 is provided at the lower end of the tube bundle 10. The sealing seat 17 is fixedly connected to the inner wall of the lower end of the tank body 1. A second hole corresponding to the first hole is opened at the end of the sealing seat 17. The lower end of the tube bundle 10 is inserted into the second hole opened on the sealing seat 17. A sealing ring 19 is fixedly connected at the lower end of the sealing seat 17 and at the position corresponding to the multiple second holes.

[0039] Furthermore, multiple baffles 16 are provided between the sealing disc 14 and the sealing seat 17. The multiple baffles 16 are arranged crosswise between the sealing disc 14 and the sealing seat 17. Each of the multiple baffles 16 has a third hole at its end that corresponds to the second hole. The tube bundle 10 is inserted into the third hole.

[0040] Through the above structural design, it can be seen that by adding chemical substances into the tank 1 through the sealing mechanism 4, and then through the obstruction of the sealing plate 14 and the sealing strip 15, the chemical substances added into the tank 1 from the sealing mechanism 4 can only flow downward through multiple tube bundles 10. The chemical substances in the tube bundles 10 can then flow into the lower end of the bottom sealing seat 17 of the tank 1. The chemical substances flowing into the lower end of the tank 1 can be discharged from the second outlet 5. Simultaneously, while adding chemical substances into the tank 1 through the sealing mechanism 4... Heat exchange water is injected into the tank 1 through the first filling port 2. The heat exchange water first fills the cavity between one of the baffles 16 and the sealing plate 14, and then continues to flow downwards to fill multiple cavities. After all cavities are filled, heat exchange water is continuously injected into the tank 1 through the first filling port 2. The heat exchange water that has flowed into the bottom of the tank 1 is discharged from the first outlet 3, thereby achieving the heat exchange effect on the chemical substances in the tube bundle 10.

[0041] Example 2:

[0042] The heat exchanger for chemical production provided in Example 1 has been further optimized, specifically, as follows: Figures 2-7 As shown, the sealing mechanism 4 includes a sealing cap 13. A second filling port 20 is provided in the middle of the upper end of the sealing cap 13. Chemical substances can be added into the interior of the tank 1 through the second filling port 20. The second filling port 20 is connected to the sealing cap 13. A connecting ring 21 is provided at the lower end of the sealing cap 13. A first slot 8 is provided at the upper end of the tank 1 and at the position corresponding to the connecting ring 21. The connecting ring 21 is inserted into the first slot 8. Insertion blocks 22 are fixedly connected to all four sides of the outer side of the connecting ring 21. A first slot 9 is provided inside the first slot 8 and at the position corresponding to the insertion block 22. The insertion block 22 is inserted into the first slot 9. A fixing pad 6 is fixedly connected to the outer side of the tank 1 and at the position corresponding to the insertion block 22. A limit mechanism 7 is provided on the outer side of the tank 1 and at the position corresponding to the fixing pad 6.

[0043] Specifically, the limiting mechanism 7 includes a handle 23, which is located on the outer side of the fixed pad 6 away from the tank 1. A screw 18 is fixedly connected to the middle of the side of the handle 23 near the fixed pad 6. The screw 18 is threadedly connected to the fixed pad 6, the tank 1, and the plug block 22.

[0044] Through the above structural design, it can be seen that when it is necessary to disassemble the conveying mechanism 11 from the inside of the tank 1 to clean the scale adhering to the tube bundle 10, multiple rotating handles 23 can be rotated. The rotating handles 23 then drive the screw 18 to separate from the fixing pad 6, the tank 1, and the plug block 22. After separation, the movement limit of the connecting ring 21 can be released, allowing the sealing cover 13 to be pulled upwards. When the sealing cover 13 moves upwards, it drives the connecting ring 21 to move upwards, thereby causing the connecting ring 21 to... 1. Pull out from the inside of the first slot 8, and at the same time, the plug block 22 is separated from the first slot 9. After removing the sealing cover 13 from the tank body 1, the sealing plate 14 can be pulled upward from the inside of the second slot 12. Then the sealing plate 14 drives the tube bundle 10 to move upward, and the tube bundle 10 moves upward in the second hole and the third hole. Then the disassembly of the conveying mechanism 11 can be completed. After the tube bundle 10 is disassembled, the scale on the tube bundle 10 can be cleaned, and the inside of the tank body 1 can be cleaned at the same time.
