Description

Technical Field

[0001] The utility model relates to the technical field of heat exchangers, in particular to a chemical heat exchanger used in chemical production. Background Art

[0002] A heat exchanger, also known as a heat exchanger, is a device that transfers some of the heat from a hot fluid to a cold fluid. Based on the heat transfer principle, heat exchangers are categorized into direct contact heat exchangers and compound heat exchangers. Based on their structure, they can be divided into floating head heat exchangers, fixed tube sheet heat exchangers, U-tube sheet heat exchangers, and plate heat exchangers. Heat exchangers play a vital role in the chemical, petroleum, power, food, and many other industrial production processes. In chemical production, heat exchangers can be used as heaters, coolers, condensers, evaporators, and reboilers, enjoying widespread applications.

[0003] The Chinese patent publication number is CN 217716051 U, and the name is a patent for a chemical heat exchanger for chemical production. By setting up a lifting mechanism, the heat exchanger can be adjusted according to actual conditions during actual use. The rotation of the dual-axis motor and the action of the bevel gear drive the threaded column to rotate. The rotation of the threaded column drives the internal threaded barrel to slide inside the fixed tube, thereby achieving height adjustment of the heat exchanger and improving the practicality of the heat exchanger.

[0004] Although the above patent can adjust the height of the heat exchanger, thereby improving the practicality of the heat exchanger, the above patent still has the following problems: when the hot fluid is added to the interior of the shell, the hot fluid cannot be stirred well, which easily causes local temperature inconsistency in the hot fluid, thereby affecting the heating effect.

[0005] In view of the above problems, a chemical heat exchanger for chemical production is proposed. Utility Model Content

[0006] The purpose of the utility model is to overcome the shortcomings of the prior art and provide a chemical heat exchanger for chemical production.

[0007] In order to achieve the above-mentioned purpose, the technical solution of the utility model is: a chemical heat exchanger for chemical production, including a heat exchanger shell, characterized in that: a partition is fixedly installed inside the heat exchanger shell, a heat exchange tube is fixedly installed on the partition, and limiting rods are fixedly installed on the upper and lower parts of the partition. A moving device is slidably connected to the surface of the limiting rod, and a return spring is movably sleeved on the limiting rod, and the two ends of the return spring are respectively fixedly connected to the moving device and the partition.

[0008] Furthermore, the mobile device includes a first mobile frame and a second mobile frame, and the first mobile frame and the second mobile frame are fixedly connected by a suspension rod.

[0009] Furthermore, the upper and lower limiting rods on the partition are respectively slidably connected to the first movable frame and the second movable frame.

[0010] Furthermore, a fixed frame is fixedly installed on the first movable frame, and a driving slide is provided on the fixed frame.

[0011] Furthermore, a drive motor is fixedly installed on the surface of the heat exchanger shell, and the output end of the drive motor rotates through the heat exchanger shell and extends to the interior of the heat exchanger shell. A rotating plate is fixedly installed on the output end of the drive motor, and a sliding column is fixedly installed on the lower end of the rotating plate. The sliding column is slidably connected inside the drive slide.

[0012] Furthermore, the first movable frame and the second movable frame are both rotatably connected to a plurality of rotating shafts, and rotating blades are fixedly mounted on the rotating shafts.

[0013] Furthermore, the end of the rotating shaft is fixedly sleeved with a driving gear, and the upper and lower partitions are fixedly mounted with racks, which are meshed and connected with the driving gear.

[0014] Beneficial effects of the present invention: In the process of the reciprocating movement of the moving device driven by the driving motor of the present invention, the driving gear is driven to rotate by meshing with the rack, and the rotation of the driving gear drives the rotating shaft and the rotating blades to rotate, thereby stirring the fluid inside the heat exchanger shell, causing the fluid inside the heat exchanger shell to move, thereby improving the full contact between the fluid and the heat exchange tube, thereby achieving uniform heating of the heat exchange tube, improving the use effect of the device, and avoiding the phenomenon of inconsistent local temperature differences.

[0021] Example:

[0022] like Figures 1 to 5 As shown, a chemical heat exchanger for chemical production includes a heat exchanger housing 1, a partition 8 fixedly mounted inside the heat exchanger housing 1, a heat exchange tube 3 fixedly mounted on the partition 8, and a limiting rod 10 fixedly mounted above and below the partition 8. A moving device is slidably connected to the surface of the limiting rod 10, and a return spring 9 is movably sleeved on the limiting rod 10, with the two ends of the return spring 9 fixedly connected to the moving device and the partition 8. The provision of the return spring 9 facilitates buffering when the moving device moves, thereby preventing the moving device from colliding with the partition 8, and improving the convenience of the device.

[0023] The moving device includes a first moving frame 4 and a second moving frame 17, which are fixedly connected via a suspension rod 16. The upper and lower limiting rods 10 of the partition 8 are slidably connected to the first moving frame 4 and the second moving frame 17 respectively.

[0024] A fixed frame 12 is fixedly mounted on the first movable frame 4, and a drive slide 14 is provided on the fixed frame 12. A drive motor 2 is fixedly mounted on the surface of the heat exchanger housing 1. The output end of the drive motor 2 rotates through the heat exchanger housing 1 and extends into the interior of the heat exchanger housing 1. A rotating plate 15 is fixedly mounted on the output end of the drive motor 2. A sliding post 13 is fixedly mounted on the lower end of the rotating plate 15. The sliding post 13 is slidably connected inside the drive slide 14.

[0025] The first and second moving frames 4 and 17 are both rotatably connected to a plurality of rotating shafts 7, on which rotating blades 11 are fixedly mounted. The ends of the rotating shafts 7 are fixedly sleeved with drive gears 6, and the upper and lower parts of the partitions 8 are fixedly mounted with racks 5, which are meshed with the drive gears 6.

[0026] Working principle:

[0027] Start the driving motor 2, so that the driving motor 2 drives the rotating plate 15 to rotate, and then synchronously drives the sliding column 13 to rotate. The sliding column 13 slides inside the driving slide 14, thereby pushing the fixed frame 12 and the first movable frame 4 to slide on the limiting rod 10, and squeezes the return spring 9, thereby realizing the reciprocating movement of the first movable frame 4, making it convenient for the first movable frame 4 and the second movable frame 17 to reciprocate. When the first movable frame 4 reciprocates, the rotating shaft 7 and the driving gear 6 will follow the first movable frame 4 to reciprocate, and the driving gear 6 will engage with the rack 5, thereby driving the driving gear 6 to rotate. The rotation of the driving gear 6 drives the rotating shaft 7 and the rotating blade 11 to rotate, thereby stirring the fluid inside the heat exchanger shell 1, thereby causing the fluid inside the heat exchanger shell 1 to move, improving the full contact between the fluid and the heat exchange tube 3, and at the same time facilitating uniform heating of the heat exchange tube 3.

[0028] The above-described embodiments are only preferred solutions of the present invention and do not limit the present invention in any form. Other variations and modifications are possible without exceeding the technical solutions described in the claims.
