[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] See also Figures 1 to 5 , the utility model provides a technical solution:

[0030] A novel heat exchange device for pipeline heat exchange comprises a heat exchange tube 1, a heat exchange component 2 is arranged inside the heat exchange tube 1, and a cleaning component 3 is arranged on one side of the heat exchange component 2;

[0031] The heat exchange assembly 2 includes an inlet pipe 201, an outlet pipe 202, an oil pipe 203 and a baffle plate 204. The inlet pipe 201 is arranged on one side of the heat exchange tube 1, the outlet pipe 202 is arranged on the other side of the heat exchange tube 1, the oil pipe 203 is arranged inside the heat exchange tube 1, and two baffle plates 204 are respectively arranged on the inner top and inner bottom of the heat exchange tube 1. The baffle plate 204 is located on one side of the heat exchange tube 1, and both ends of the oil pipe 203 extend through and extend to the top and bottom of the heat exchange tube 1 respectively.

[0032] Specifically, Figure 4 As shown, a fixing ring 301 and a vibrator 302 are provided at the top outer end of the inlet tube 201 . The fixing ring 301 is provided at the top of the heat exchange tube 1 , and the vibrator 302 is provided at one side of the fixing ring 301 .

[0033] Specifically, Figure 2 As shown, a stainless steel chain 4 is arranged inside the heat exchange tube 1 , a stainless steel ball 5 is arranged at the bottom of the stainless steel chain 4 , and the stainless steel ball 5 is located at one side of the oil pipe 203 .

[0034] Specifically, Figure 1 As shown, a sleeve 6 is provided on one side of the discharge pipe 202 , and a sealing gasket 7 is provided inside the sleeve 6 .

[0035] Specifically, Figure 2 As shown, a flange 10 is provided on one side of the inlet pipe 201, and bolt holes 11 are provided on one side of the flange 10. A plurality of bolt holes 11 are arranged in a circumferential array on one side of the surface of the flange 10.

[0036] Cold water is injected into the interior of the heat exchange tube 1 through the inlet pipe 201, and the oil at high temperature is transported through the oil pipe 203. At this time, the cold water contacts the oil pipe 203 to cool the oil. At this time, the cold water contacts the oil pipe 203 and also becomes hot. The blocking plate 204 limits the contact of the cold water. The contact area between the curved oil pipe 203 and the cold water increases, thereby improving the heat exchange efficiency of the oil pipe 203. The top of the oil pipe 203 is contacted by the fixing ring 301, and the fixing ring 301 is vibrated by the vibrator 302. At this time, the fixing ring 301 makes the surface of the oil pipe 203 Vibration makes it difficult for scale to adhere to the surface of the oil pipe 203. When cold water enters the interior of the heat exchange tube 1, it will impact the stainless steel chain 4. At this time, the stainless steel ball 5 at the bottom of the stainless steel chain 4 will hit the surface of the heat exchange tube 1. At this time, the scale attached to the surface of the heat exchange tube 1 is knocked off, and the water pipe is connected through the sleeve 6. The pipe connected to the sleeve 6 and the heat exchange tube 1 can be sealed through the sealing gasket 7. The flange 10 allows the pipe to be connected to one side of the entry pipe 201. The bolt hole 11 can fix the flange 10 and the one side of the connected pipe for bolting.

[0037] Specifically, Figure 1 As shown, a heat-insulating layer 8 is arranged on the outer side of the heat exchange tube 1 , and the material of the heat-insulating layer 8 is pearl cotton 9 .

[0038] By setting the insulation layer 8 of pearl cotton 9, the interior of the heat exchange tube 1 can be relatively insulated. Pearl cotton 9 is a new type of insulation material, which is composed of many small bubbles. These small bubbles can effectively isolate air circulation, thereby playing a role in insulation. Compared with traditional insulation materials, pearl cotton 9 has higher insulation performance and lighter weight, so it is widely used in various occasions requiring insulation, such as construction, automobiles, home appliances, etc. The insulation principle of pearl cotton 9 is mainly through its unique pore structure, which makes the air encounter great resistance when flowing, thereby slowing down the heat transfer speed. At the same time, the pore structure of pearl cotton 9 can also reflect heat radiation, further improving the insulation effect.

[0039] Specifically, Figure 1 As shown, a hanging plate 12 is provided on the top of the heat exchange tube 1 , and the hanging plate 12 is located on one side of the top of the oil pipe 203 .

[0040] By providing the hoisting plate 12 , the heat exchange tube 1 can be hoisted to the required area for placement.

[0041] Specifically, Figure 1 As shown, three supporting legs 13 are arranged at the bottom of the heat exchange tube 1, and the diameter of the supporting legs 13 gradually decreases from the top to the bottom.

[0042] The bottom of the heat exchange tube 1 can be supported by providing the support legs 13 .

[0043] By adopting the above technical solution, the problem that the amount of oil passing through the existing single pipeline at one time is too small and the cooling efficiency of the oil in the pipeline is slow is solved.

[0044] Working principle: When the present application is used, first, cold water is injected into the heat exchange tube 1 through the inlet pipe 201, and the oil at high temperature is transported through the oil pipe 203. At this time, the cold water contacts the oil pipe 203 to cool the oil. At this time, the cold water contacts the oil pipe 203 and also becomes hot. The blocking plate 204 limits the contact of the cold water, and the contact area between the bent oil pipe 203 and the cold water is increased, thereby increasing the heat exchange efficiency of the oil pipe 203. The top of the oil pipe 203 is contacted through the fixing ring 301, and the fixing ring 301 is vibrated through the vibrator 302. At this time, the fixing ring 301 vibrates the surface of the oil pipe 203, so that scale is not easily attached to the surface of the oil pipe 203. When the cold water enters the heat exchange tube 1, the fixing ring 301 is used to vibrate the surface of the oil pipe 203, and the fixing ring 301 is used to vibrate the surface of the oil pipe 203. The stainless steel chain 4 will be impacted when the stainless steel chain 4 is moved downwards. At this time, the stainless steel ball 5 at the bottom of the stainless steel chain 4 will hit the surface of the heat exchange tube 1. At this time, the scale attached to the surface of the heat exchange tube 1 will be knocked off. The water pipe is connected through the sleeve 6. The sleeve 6 and the heat exchange tube 1 connecting pipe can be sealed through the sealing gasket 7. The pipe connection can be made on one side of the inlet pipe 201 through the flange 10. The flange 10 and the connecting pipe side can be fixed and bolted through the bolt hole 11. The inside of the heat exchange tube 1 can be relatively insulated by arranging the pearl cotton 9 insulation layer 8. The heat exchange tube 1 can be hoisted to the required area for placement by arranging the lifting plate 12. The bottom of the heat exchange tube 1 can be supported by arranging the support legs 13.

[0045] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
