Description

TECHNICAL FIELD

[0001] The utility model relates to heat exchanger technical field more specifically, it relates to a kind of for pharmaceutical equipment's heat exchanger. BACKGROUND

[0002] In the prior art, although the heat exchanger used in pharmaceutical equipment has achieved heating or cooling of materials to some extent, it often faces problems such as uneven heat exchange process and inaccurate temperature control, resulting in unsatisfactory overall heat exchange effect. The contact area and flow rate distribution between the heat exchange medium in the heat exchanger and the material being heated or cooled may not be uniform, which may be due to unreasonable internal pipe layout of the heat exchanger or large difference in fluid flow rate, causing temperature to be too high in some areas while other areas fail to be effectively heated or cooled.

[0003] If the material injection speed is too fast, the heat exchanger may not be able to fully adjust its temperature, resulting in that the heat exchange process of the material cannot proceed smoothly, and the too fast material addition may cause insufficient residence time of the material in the heat exchanger, incomplete heat exchange, and difficult temperature control, which not only affects the heating or cooling effect of the material, but also may cause incomplete reaction, ultimately affecting product quality. On the other hand, if the material injection is too slow, the work load of the heat exchanger may be too concentrated, and the heat exchange capacity of the heat exchanger cannot achieve large-scale heat transfer in a short time, resulting in low heat exchange efficiency. The slow flow rate may cause the contact time of the heat medium and the material to be too long, resulting in excessive heat loss or temperature fluctuation, and also may cause part of the material to fail to be fully treated within the required time.

At the top end of box 2, the feeding adjustment mechanism includes an adjustment pipe 9, a fixed plate 10, a connecting pipe 11, a connecting hole 12, a directional block 13, and a threaded rod 14.

A threaded rod 14 is installed at one end of the directional block 13. The sliding of the directional block 13 can block the connecting hole 12 and control the flow rate in the adjustment pipe 9.

[0030] In this embodiment, the shaking motor 4 is installed on the top of the tilting plate 3. The rotational motion is converted into the shaking motion of the heat exchange box 2 via the eccentric disc 5 and eccentric rod 6. The heat exchange box 2 is supported by the mounting rod 24.

[0033] Please see Figures 1-5 As a supplementary embodiment of a heat exchanger for pharmaceutical equipment, which includes a shaking mechanism, a feeding adjustment mechanism, and an adjustment auxiliary mechanism: A side plate 20 is installed on the top end of the base 1, and a hydraulic cylinder 21 is rotatably installed between the side plate 20 and the tilting plate 3. Supports are symmetrically installed on the top end of the base 1, and rotating shafts 22 are installed on both sides of the tilting plate 3. The rotating shafts 22 are supported and rotated on the supports. A processing box assembly 23 is installed on the top end of the tilting plate 3, and a placement rod 24 is installed on the top end of the processing box assembly 23. The heat exchange box 2 is rotatably mounted on the placement rod 24. A corrugated pipe 25 is installed between the bottom end of the heat exchange box 2 and the processing box assembly 23.

[0034] More specifically, when the equipment starts working, external material is supplied into the regulating pipe 9 through the feed pipe 8. The feed regulating mechanism controls the feed flow rate by adjusting the cooperation of the directional block 13 and the threaded rod 14. At the same time, the shaking mechanism starts, and the shaking motor 4 drives the eccentric disk 5. The eccentric disk 5 drives the eccentric rod 6 to shake the heat exchange box 2. The heat exchange tubes 7 inside the heat exchange box 2 enhance the heat exchange efficiency of the fluid as the box shakes. The feed regulating mechanism adjusts the feed flow rate according to the needs to ensure that the flow rate is appropriate during the heat exchange process. The regulating auxiliary mechanism ensures the stability of the regulating pipe 9 through the cooperation of the rotating sleeve 15 and the threaded bracket 16, making the entire regulation process more precise and efficient. By continuously adjusting the feed flow rate and optimizing the heat exchange process, the equipment can efficiently heat or cool during the pharmaceutical process to achieve the required temperature control effect.

[0035] In summary, during the use or operation of the overall equipment: when the shaking mechanism is required, the shaking motor 4 is installed on top of the tilting plate 3, and converts the rotational motion into the shaking motion of the heat exchange box 2 through the eccentric disc 5 and eccentric rod 6. The heat exchange box 2 is supported by the support rod 24, and its bottom is connected to the processing box assembly 23 through a corrugated pipe 25 to ensure unobstructed pipeline flow. The heat exchange pipe 7 is installed inside the heat exchange box 2 and is connected to external heating or cooling equipment through the connecting pipe 26. The feed pipe 8 passes through the top of the heat exchange box 2 to realize material conveying. The hydraulic cylinder 21 controls the tilt angle of the tilting plate 3 to further optimize the heat exchange effect.

[0036] When the feed adjustment mechanism is in operation, the adjustment pipe 9 is fixedly connected to the feed pipe 8. The connecting pipe 11 installed on the internal fixed plate 10 is provided with multiple sets of connecting holes 12. The directional block 13 slides in the connecting pipe 11. The flow rate is adjusted by changing the number of connecting holes 12 blocked. The directional block 13 is connected by a threaded rod 14 to achieve precise position control. This multi-channel design, combined with the sliding adjustment of the directional block 13, can achieve step-like precise control of the flow rate.

[0037] When the auxiliary mechanism needs adjustment, the rotating sleeve 15 is limited to rotating on the outer wall of the adjusting tube 9. The threaded bracket 16 on its inner wall forms a threaded drive with the threaded rod 14 of the directional block 13. Thus, the rotation of the rotating sleeve 15 drives the directional block 13 to move. The rotating block 17 is installed on the end face of the rotating sleeve 15 and forms a stabilizing mechanism with the centripetal block 201 on the fixed ring 18. The centripetal block 201 slides on the centripetal rail 27, and the tensioning spring 19 between adjacent centripetal blocks 201 provides continuous pressure to ensure that the rotating sleeve 15 rotates smoothly. This design ensures both the accuracy of adjustment and improves operational stability.

[0038] When the equipment starts working, external material is supplied through the feed pipe 8 into the regulating pipe 9. The feed regulating mechanism controls the feed flow rate by adjusting the cooperation of the directional block 13 and the threaded rod 14. At the same time, the shaking mechanism starts, and the shaking motor 4 drives the eccentric disk 5. The eccentric disk 5 drives the eccentric rod 6 to shake the heat exchange box 2. The heat exchange tubes 7 inside the heat exchange box 2 enhance the heat exchange efficiency of the fluid as the box shakes. The feed regulating mechanism adjusts the feed flow rate according to the needs to ensure that the flow rate is appropriate during the heat exchange process. The regulating auxiliary mechanism ensures the stability of the regulating pipe 9 through the cooperation of the rotating sleeve 15 and the threaded bracket 16, making the entire regulation process more precise and efficient. By continuously adjusting the feed flow rate and optimizing the heat exchange process, the equipment can efficiently heat or cool during the pharmaceutical process to achieve the required temperature control effect.
