Description

Technical Field

[0001] This utility model relates to the field of pre-separation technology of methylchlorosilane mixed crude monomers, specifically to a pre-separation tower for methylchlorosilane mixed crude monomers with a high-efficiency heat dissipation structure. Background Technology

[0002] As a crucial component of the modern chemical new materials field, the quality of the basic raw materials in the organosilicon industry directly determines the performance and competitiveness of downstream products. Methylchlorosilane, as a core basic raw material for the production of various organosilicon products, is typically prepared through direct synthesis in the form of mixed crude monomers.

[0003] Traditional separation equipment uses towers, which generate a lot of heat during the separation of methylchlorosilane. Existing pre-separation towers typically use heat dissipation fins for heat dissipation, which is a relatively simple structure with poor heat dissipation effect, causing local overheating and greatly affecting monomer purity and separation efficiency. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the above-mentioned technical difficulties and provide a pre-separation tower for mixed crude monomers of methylchlorosilane with a highly efficient heat dissipation structure. The heat dissipation structure is diversified, the heat dissipation is more efficient, and the purity of the monomers and the separation efficiency are greatly improved.

[0005] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows: a pre-separation tower for mixed crude monomers of methylchlorosilane with a high-efficiency heat dissipation structure, comprising a tower body, a circulating cold water tank provided on the bottom surface of the tower body, a cold water inlet pump and a drain pump provided on one side of the circulating cold water tank, a heat dissipation inner cylinder fixedly connected to the inner wall of the tower body, a plurality of heat-conducting blocks fixedly connected to the outside of the heat dissipation inner cylinder, a heat dissipation outer cylinder sleeved on the outer wall of the tower body fixedly connected to one end of the heat-conducting blocks extending to the outside of the tower body, uniformly arranged heat dissipation fins fixedly connected to the outer wall of the heat dissipation outer cylinder, a serpentine heat dissipation pipe arranged in a ring array fixedly connected to the inner wall of the heat dissipation inner cylinder, an inlet pipe and an outlet pipe extending into the circulating cold water tank respectively fixedly connected to both ends of the serpentine heat dissipation pipe; a rotating ring rotatably connected to the outer wall of the tower body, a rotating mechanism for driving the rotating ring to rotate, a connecting arm arranged in a ring array fixedly connected to the outer wall of the rotating ring, and a cooling fan located on one side of the heat dissipation fins fixedly connected to one end of the connecting arm.

[0006] As an improvement, the inner wall of the heat dissipation cylinder is fixedly connected with annular heat dissipation fins arranged vertically, and the serpentine heat dissipation tube is fixedly inserted into the annular heat dissipation fins.

[0007] As an improvement, the annular heat sink is provided with through-holes for heat dissipation.

[0008] As an improvement, the rotating mechanism includes a gear ring fixedly sleeved on the outer wall of the rotating ring, a motor fixedly connected to the outer wall of the tower body, and a gear meshing with the gear ring fixedly connected to the output end of the motor.

[0009] As an improvement, an annular limiting guide rail that cooperates with the rotating ring is fixedly connected to the outer wall of the tower body.

[0010] As an improvement, the lower ends of the heat dissipation fins are all fixedly connected to connecting fins that extend into the circulating cold water tank.

[0011] The advantages of this invention compared to existing technologies are as follows: the heat is absorbed by the heat dissipation inner cylinder and the serpentine heat dissipation pipes. The serpentine heat dissipation pipes transport the heat to the circulating cold water tank through the water outlet pipe, and then cold water is introduced through the water inlet pipe for heat dissipation again. The heat dissipation inner cylinder transfers the heat to the heat dissipation fins of the heat dissipation outer cylinder through the heat conduction block for heat dissipation. The cooling fan is driven by the rotating mechanism to circulate air cooling to the heat dissipation fins, which greatly improves the heat dissipation efficiency. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0020] like Figures 1 to 6 As shown, a pre-separation tower for mixed crude monomers of methylchlorosilane with a high-efficiency heat dissipation structure includes a tower body 1.

A heat dissipation inner cylinder 5 is fixedly connected to the inner wall of the tower body 1. A plurality of heat-conducting blocks 7 are fixedly connected to the outside of the heat dissipation inner cylinder 5. A heat dissipation outer cylinder 6 sleeved on the outer wall of the tower body 1 is fixedly connected to one end of the heat-conducting blocks 7 extending to the outside of the tower body 1. A uniformly arranged heat dissipation fins 9 are fixedly connected to the outer wall of the heat dissipation outer cylinder 6. A connecting fin 10 extending into the circulating cold water tank 2 is fixedly connected to the lower end of each heat dissipation fin 9.

[0021] The inner wall of the heat dissipation inner cylinder 5 is fixedly connected with a serpentine heat dissipation pipe 12 arranged in a ring array. The inner wall of the heat dissipation inner cylinder 5 is fixedly connected with an annular heat dissipation fin 8 arranged vertically. The serpentine heat dissipation pipe 12 is fixedly inserted into the annular heat dissipation fin 8. The annular heat dissipation fin 8 is provided with heat dissipation holes 11 arranged through. The two ends of the serpentine heat dissipation pipe are respectively fixedly connected with an inlet pipe 13 and an outlet pipe 14 extending into the circulating cold water tank 2. One end of the inlet pipe 13 is fixedly connected to a flow guide pump.

[0022] The heat inside the tower body 1 is transferred to the heat dissipation outer cylinder 6 on the outer wall of the tower body 1 through the heat dissipation inner cylinder 5 and the heat conduction block 7 via the annular heat dissipation fin 8. The heat is then dissipated through the heat dissipation fins 9, the lower end of which is connected to the connecting fins 10. The connecting fins 10 dissipate heat independently while being further cooled by the cold water in the circulating cold water tank 2. The heat dissipation holes 11 on the annular heat dissipation fin 8 can further expand the contact area with the hot air and improve the heat absorption effect. At the same time, the cold water in the serpentine heat dissipation pipe 12 quickly absorbs the heat inside the tower body 1 and the heat from the annular heat dissipation fin 8, and the hot water is discharged into the circulating cold water tank 2 through the drain pipe. The cold water inlet pump 3 and the drain pump 4 can keep the water temperature in the circulating cold water tank 2 constant at all times.

[0023] The outer wall of the tower body 1 is rotatably connected to a rotating ring 15. The outer wall of the tower body 1 is fixedly connected to an annular limiting guide rail 21 that cooperates with the rotating ring 15. The tower body 1 is provided with a rotating mechanism that drives the rotating ring 15 to rotate. The outer wall of the rotating ring 15 is fixedly connected to a connecting arm 17 arranged in an annular array. One end of the connecting arm 17 is fixedly connected to a cooling fan 18 located on one side of the heat dissipation fin 9. The rotating mechanism includes a gear ring 16 fixedly sleeved on the outer wall of the rotating ring 15. The outer wall of the tower body 1 is fixedly connected to a motor 19. The output end of the motor 19 is fixedly connected to a gear 20 that meshes with the gear ring 16.

[0024] The starter motor 19 drives the gear 20 to rotate, and the gear 20 drives the gear ring 16 to drive the rotating ring 15 to rotate along the annular limit guide rail 21. The rotating ring 15 drives the cooling fan 18 through the swing arm to circulate air cooling to the heat dissipation fins 9, which greatly improves the heat dissipation efficiency.
