Description

Technical Field

[0001] The utility model belongs to the technical field of sealant production, and in particular relates to heat exchange equipment for preparing two-component sealant. Background Art

[0002] Sealant is an adhesive used to fill the gaps in the structure to perform a sealing function. During the production process, the sealant needs to be quickly cooled after high-temperature dispersion treatment, so that it can be cooled to room temperature for secondary dispersion treatment. After a long period of cooling treatment, a large amount of glue will adhere to the heat exchange tubes of traditional shell and tube heat exchange equipment, which greatly reduces the cooling effect of the heat exchange tubes. Therefore, it is necessary to manually disassemble, clean and maintain them regularly, thereby increasing the labor burden. Chinese patent document: CN202320870912.9, discloses an improved shell and tube heat exchanger, which provides a movable and adjustable cleaning scraper inside the shell and tube heat exchanger, and drives the cleaning scraper back and forth by driving the heat flow direction and the adjustable component, so that the cleaning scraper cleans the heat exchange tube wall of the heat exchanger inside the heat exchanger. In this application, the cleaning slide frame is arranged above the heat flow inlet tube so that the heat flow drives the cleaning slide frame to move. In actual use, since the scraper contacts the surfaces of several heat exchange tubes at the same time, this causes a large friction resistance between the scraper and the heat exchange tube group, making it impossible for the scraper to move smoothly on the heat exchange tube, thereby affecting the cleaning effect. In addition, baffles are provided in most heat exchangers, so the cleaning structure cannot adapt to most heat exchanger structures, thereby failing to effectively realize the cleaning function. Utility Model Content

[0003] In view of the above problems, the utility model discloses a heat exchange device for preparing a two-component sealant, which solves the problem in the prior art that the heat exchanger needs to be manually disassembled and cleaned, resulting in a heavy labor burden.

[0004] The specific technical solutions are as follows:

[0011] The beneficial effects of the utility model are embodied in:

[0012] When the utility model cleans the heat exchange tube, the heat exchange component rotates and cooperates with the spray pipe to flush the heat exchange tube. At the same time, the heat exchange tube is repeatedly immersed in the liquid in the tube shell during the rotation process, so that the glue and adhesive on the surface of the heat exchange tube can fall off under the impact of water flow and centrifugal action, thereby achieving the cleaning effect of the heat exchange tube, without manual disassembly and cleaning, and greatly improving the cleaning efficiency.

The two ends of the tube shell 1 are respectively provided with a feed pipe 11 and a discharge pipe 12 for the rubber material to enter and exit. The heat exchange component is rotatably arranged in the tube shell 1, and the heat exchange component includes two fixed disks 3 rotatably arranged at both ends of the tube shell 1 and a plurality of heat exchange tubes 4 transversely arranged between the two fixed disks 3. A circle of sealing seats 101 are arranged on the inner walls at both ends of the tube shell 1, and the sealing seats 101 are rotatably connected to the side of the fixed disk 3 through a sealing bearing. The two ends of each heat exchange tube 4 pass through the two fixed disks 3 and are respectively connected to the inner cavities of the two heads 2, one of which is a cylindrical structure and is horizontally connected with a liquid outlet pipe 22, and the other head 2 is conically contracted and is provided with a liquid inlet pipe 21.

[0019] A spray pipe 5 is horizontally connected to the center of the two fixed disks 3, and a plurality of spray heads 51 are arranged on the spray pipe 5, so that the spray heads 51 spray cleaning liquid into the tube shell 1 and clean the surface of the heat exchange tube 4, and a drain pipe 13 for discharging the cleaning liquid is provided at the bottom of the tube shell 1. Both ends of the spray pipe 5 are rotatably connected to the two fixed disks 3 through bearings, and one end of the spray pipe 5 passes through one of the fixed disks 3 and extends into the liquid inlet pipe 21 of the head 2. A bracket is provided in the liquid inlet pipe 21 for supporting and positioning the spray pipe 5. The spray pipe 5 vertically passes through the side wall of the liquid inlet pipe 21 and is connected to the external water source, so that the spray pipe 5 can spray and clean the inner wall of the tube shell 1. A rotating shaft 31 is horizontally provided at the center of one end of the other fixed disk 3, and one end of the rotating shaft 31 passes through the head 2. At the same time, a driving motor 6 is installed on the outer wall of the head 2 through a motor seat.

[0020] In this embodiment, a plurality of baffles 7 are arranged transversely on a plurality of heat exchange tubes 4, the baffles 7 are arranged longitudinally and fixedly connected to the heat exchange tubes 4, and the plurality of baffles 7 are staggered in distribution.

The PLC controller is electrically connected to the liquid level sensor 102, the first solenoid valve 52 and the second solenoid valve 131 respectively. When the liquid level sensor 102 detects that the liquid level has reached a predetermined value, it sends a signal to the PLC controller, which controls the second solenoid valve 131 to open and drain the liquid to prevent the liquid level in the tube shell 1 from being too high. This allows the reversing tube to generate impact when it is immersed in the liquid during the rotation of the reversing component, thereby improving the effect of cleaning the reversing tube.
