Description

Technical Field

[0001] The utility model relates to the field of heat recovery devices, in particular to a heat recovery device of a tubular sterilizer. Background Art

[0002] A heat exchanger (also known as a heat exchanger or heat exchange equipment) is a device used to transfer heat from a hot fluid to a cold fluid to meet specified process requirements. It is an industrial application of convective heat transfer and heat conduction. During the use of a shell-and-tube sterilizer, liquids such as beverages are sterilized at high temperatures, and the sterilized liquid beverages need to be cooled. When cooling the beverages, the heat can be transferred to the cold drinking water through the heat exchanger, thereby recycling the heat during cooling and avoiding heat waste. When using a heat exchanger, the liquid beverage pipeline on the shell-and-tube sterilizer and the heat medium inlet and heat medium outlet of the heat exchanger are often connected as a whole. When connecting drinking water to the heat exchanger, they are often connected through a hose. When the refrigerant user device at the end of the hose away from the heat exchanger is inspected and replaced, the end of the hose away from the heat exchanger often needs to be removed from the refrigerant user device, while the end of the hose connected to the heat exchanger does not need to be removed. At this time, if the hose is too long, it is easy to drag on the ground, easily getting dirty or causing damage.

[0003] For example, the utility model disclosed in the publication (announcement) number: CN217979986U discloses a heat recovery device for a shell-and-tube sterilizer. This application includes a heat exchanger, the surface of which is connected to a refrigerant outlet, a refrigerant inlet, a heat medium inlet and a heat medium outlet. The surfaces of the refrigerant inlet and the refrigerant outlet are both covered with hoses. The surface of the heat exchanger is provided with a limiting structure, which includes a limiting block fixedly connected to the heat exchanger, and the surfaces of the two limiting blocks are respectively covered with a first arc plate and a second arc plate connected together by bolts. The surface of the second arc plate is fixedly connected to a limiting frame, and the interior of the limiting frame is rotatably connected to a screw, and the surface of the screw is threaded with a slider, and the surface of the slider is rotatably connected to a rotating plate, and a connecting structure is provided between the slider and the rotating plate. This solves the problem that the hose does not need to be disassembled at one end where the hose is connected to the heat exchanger, and that the hose is too long and easily dragged on the ground, easily dirty or damaged.

[0004] The device of the above-mentioned utility model is convenient for fixing the hose, thereby avoiding the problem of the hose becoming dirty or broken when mopping the floor. However, when the device of the above-mentioned utility model fixes the hose, the pipe connection end of the hose is exposed to the outside, and dust is easily attached to the pipe end. In the subsequent connection process with other devices, it is easy to cause contamination of the device connection and affect its use. At the same time, during the hose fixing process, the moisture remaining on the inner wall of the hose is easy to flow down along the inner wall of the hose, causing the ground to be wet or dripping onto the surface of the equipment.

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0018] Example 1

[0019] See also Figure 1-Figure 2The heat recovery device of a shell and tube sterilizer shown in the figure includes a heat exchanger 1 with a refrigerant outlet 2, a refrigerant inlet 13, a heat medium inlet 14 and a heat medium outlet 15 on the surface. The refrigerant outlet 2 and the refrigerant inlet 13 are both covered with a hose 3, and a first limiting collar 4 and a second limiting collar 5 are fixedly installed on the outer side of the heat exchanger 1. The top of the first limiting collar 4 and the bottom end of the second limiting collar 5 are respectively fixedly connected to a first fixing component 6, and the bottom end of the first limiting collar 4 and the top end of the second limiting collar 5 are respectively fixedly connected to a second fixing cover 7 with a groove. Each second fixing cover 7 is threadedly connected with a screw 8 in the vertical direction, and the bottom end of the screw 8 is rotatably connected to a fixing plate 9 that is in sliding contact with the inner wall of the groove of the second fixing cover 7. A second fixing rubber pad 10 is fixedly provided on the end of each fixing plate 9 away from the screw 8, and a water-absorbing sponge 11 is fixedly provided on the inner wall of the groove of each second fixing cover 7 close to the end of the heat exchanger 1.

[0020] In this embodiment, each first fixing component 6 includes a first fixing block 61 with a groove, and the first fixing block 61 has sliding grooves on both sides along the vertical direction. A connecting plate 63 is slidably provided in the groove of the first fixing block 61, and the two ends of the connecting plate 63 are fixedly connected with sliders 62 that are slidably connected to the groove of the first fixing block 61. A first magnet 64 is embedded and fixedly installed at the center position of the bottom end of the connecting plate 63, and a first fixed rubber pad 65 is bonded and fixed to the bottom end of the first magnet 64. A second magnet 66 that is attracted to the first magnet 64 is fixedly installed at the bottom end of the groove of the first fixing block 61, and each screw 8 is fixedly connected to the adjusting disk 12 at one end away from the heat exchanger 1.

[0021] Furthermore, when the hose 3 is not in use, after removing one end of the refrigerant outlet 2 and the refrigerant inlet 13, first slide each connecting plate 63 out of the first fixed block 61 through the sliders 62 on both sides, put the outer side of each hose 3 into the groove of the first fixed block 61, and then each connecting plate 63 is moved along the slide groove of the first fixed block 61 toward one end of the second magnet 66 through the sliders 62 at both ends, so that the hose 3 is clamped and fixed in the groove of the first fixed block 61 under the action of the mutual attraction between the first magnet 64 and the second magnet 66. The first fixed rubber pad 65 is provided to increase friction. The force is also prevented from being damaged by excessive force on the hose 3. Then, each port of the hose 3 is placed in the second fixed cover 7 respectively. By rotating the adjusting disk 12 and combining the screw 8 with the threaded adjustment process of the second fixed cover 7, the port of the hose 3 is pressed and fixed in the second fixed cover 7 through the fixing plate 9 at one end of each screw 8, thereby preventing the port of the hose 3 from being exposed to dust and being contaminated. The water-absorbing sponge 11 arranged in the second fixed cover 7 is used to absorb the residual water stains attached to the inner wall of the hose 3. The second fixed rubber pad 10 is used to increase the friction force and also prevent the hose 3 from being damaged by excessive force.

[0022] The working principle of the present invention is as follows: when the hose 3 is not in use, after removing one end of the refrigerant outlet 2 and the refrigerant inlet 13, first slide each connecting plate 63 out of the first fixing block 61 through the sliders 62 on both sides, put the outer side of each hose 3 into the groove of the first fixing block 61, and then move each connecting plate 63 along the slide groove of the first fixing block 61 toward one end of the second magnet 66 through the sliders 62 at both ends, so that the hose 3 is clamped and fixed in the groove of the first fixing block 61 under the action of the mutual attraction between the first magnet 64 and the second magnet 66. The first fixed rubber pad 65 is provided to increase the pressure. While increasing friction, it also prevents the hose 3 from being damaged by excessive force. Then, each port of the hose 3 is placed inside the second fixed cover 7 respectively. By rotating the adjusting disk 12 and combining the screw 8 with the threaded adjustment process of the second fixed cover 7, the port of the hose 3 is pressed and fixed inside the second fixed cover 7 through the fixing plate 9 at one end of each screw 8, thereby preventing the port of the hose 3 from being exposed to dust and contamination. The water-absorbing sponge 11 arranged in the second fixed cover 7 is used to absorb the residual water stains attached to the inner wall of the hose 3. The second fixed rubber pad 10 is used to increase friction while also preventing the hose 3 from being damaged by excessive force.
