Description

Technical Field

[0001] This utility model relates to the field of heat exchanger technology, and in particular to a heat exchanger for a pasteurization device. Background Technology

[0002] Pasteurization, also known as pasteurization, works on the principle that within a certain temperature range, lower temperatures slow down bacterial reproduction, while higher temperatures accelerate it. However, excessively high temperatures kill the bacteria. Different bacteria have different optimal growth temperatures and varying degrees of heat and cold resistance. Pasteurization essentially utilizes the fact that pathogens are not very heat-resistant, using appropriate temperatures and holding times to kill them completely. Currently, pasteurization is generally performed on materials using heat exchangers, which utilize flowing hot water to heat the materials.

[0003] Currently, plate heat exchangers are generally used for pasteurization. However, plate heat exchangers often result in incomplete sterilization of materials due to uneven heating within the heat exchanger. Furthermore, after a period of use, proteins in the materials will produce precipitates when heated. These precipitates will accumulate and adhere to the inside of the heat exchanger, affecting its hygiene over time. Therefore, regular cleaning is necessary. However, the disassembly of currently used plate heat exchangers is quite complex and cumbersome, making it very inconvenient.

[0004] Therefore, it is necessary to improve the existing technology to solve the above-mentioned technical problems. Utility Model Content

[0007] As a further technical solution of this utility model, the upper end of the outer wall of the connecting base plate is symmetrically and fixedly connected with support frames, and the outer walls of the two support frames are rotatably connected with rotating rods on opposite sides. The connecting frame is fixedly connected to the two rotating rods at the same time.

[0013] Beneficial effects:

[0014] 1. This utility model inputs hot water into the spiral heat exchange frame in the connecting frame through the input pipe.

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.

[0023] Please see Figure 1-5This utility model provides a heat exchanger solution for a pasteurization device: It includes a connecting base plate 100, a rotatable connecting frame 200 at the upper end of the outer wall of the connecting base plate 100, a cover plate 210 detachably connected to the rear side of the outer wall of the connecting frame 200, connecting columns 300 fixedly connected circumferentially to the inner wall of the connecting frame 200, and a spiral heat exchange frame 310 fixedly installed on all the connecting columns 300. An input pipe 400 penetrating the front end of the outer wall of the connecting frame 200 is fixedly connected to the middle of the spiral heat exchange frame 310, and an output pipe 410 penetrating the outer wall of the connecting frame 200 is fixedly connected to the end of the spiral heat exchange frame 310. The cover plate 210... A feed pipe 500 is fixedly installed on the rear side of the outer wall, and a discharge pipe 510 is fixedly installed on the front side of the outer wall of the connecting frame 200. The device inputs the material to be sterilized into the connecting frame 200 through the feed pipe 500, and at the same time, hot water is input into the spiral heat exchange frame 310 in the connecting frame 200 through the input pipe 400. After the hot water enters the spiral heat exchange frame 310 through the input pipe 400, it will heat the inside of the connecting frame 200, thereby sterilizing the material in the connecting frame 200. The hot water flows to the end of the spiral heat exchange frame 310 and is discharged from the output pipe 410. The sterilized material can be discharged from the discharge pipe 510.

[0024] Support frames 110 are symmetrically fixedly connected to the upper outer wall of the connecting base plate 100. Rotating rods 120 are rotatably connected to the opposite sides of the outer walls of the two support frames 110. The connecting frame 200 is fixedly connected to both rotating rods 120. The rotation of the rotating rods 120 can realize the rotation of the connecting frame 200, and the angle of the connecting frame 200 can be adjusted. The left end of the rotating rod 120 on the left passes through the support frame 110 and is fixedly connected to the rotating disk 600. The rotating disk 600 has a first insertion hole 610 arranged in a circular pattern, and the left support frame 110 has a second insertion hole 620 arranged in a circular pattern. Bolts 630 are inserted into both the first insertion hole 610 and the second insertion hole 620. The tail end of the bolt 630 is threaded with a nut 640. The bolts 630 in the first insertion hole 610 and the second insertion hole 620 can fix the rotation angle of the connecting frame 200. The inner diameters of the first insertion hole 610 and the second insertion hole 620 are the same and their positions correspond one-to-one, which facilitates the insertion of the bolts 630.

[0025] like Figure 1-4As shown, the connecting frame 200 has a mounting groove 700 at its rear end. Connecting blocks 1 710 are fixedly mounted circumferentially on the side wall of the connecting frame 200, and connecting blocks 220 are fixedly mounted circumferentially on the side wall of the cover plate 210. Mounting screws 730 are threaded onto both connecting blocks 220 and connecting blocks 1 710. Personnel can remove the cover plate 210 by unscrewing the mounting screws 730, thereby opening the connecting frame 200 for easy cleaning of its interior. A rubber sealing ring 800 is fixedly mounted on the front side of the outer wall of the cover plate 210, corresponding to the mounting groove 700. The rubber sealing ring 800 is used to increase the sealing performance of the cover plate 210 and the connecting frame 200 during installation.

[0026] The working principle of this utility model is as follows: During use, the device inputs the material to be sterilized into the connecting frame 200 through the feed pipe 500, and simultaneously inputs hot water into the spiral heat exchange frame 310 in the connecting frame 200 through the input pipe 400. After the hot water enters the spiral heat exchange frame 310 through the input pipe 400, it heats the inside of the connecting frame 200, thereby sterilizing the material in the connecting frame 200. The hot water flows to the end of the spiral heat exchange frame 310 and is discharged from the output pipe 410. The sterilized material can be discharged from the discharge pipe 510. At the same time, the connecting frame 200 can be rotated by rotating the rotating rod 120, which can realize the angle adjustment of the connecting frame 200. The rotation angle of the connecting frame 200 can be fixed by bolts 630 in the first insertion hole 610 and the second insertion hole 620. When it is necessary to clean the inside of the connecting frame 200, personnel can remove the cover plate 210 by unscrewing the mounting screws 730, thereby opening the connecting frame 200 and facilitating cleaning of the inside of the connecting frame 200.

[0027] The above are merely preferred embodiments of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
