Description

Technical Field

[0001] This utility model belongs to the technical field of asphalt coolers, and specifically relates to an asphalt cooler. Background Technology

[0002] During the production and processing of asphalt, high-temperature asphalt needs to be cooled to meet the requirements of subsequent storage, transportation, and use. Currently, common asphalt cooling methods include natural cooling, water cooling, and air cooling. Natural cooling is extremely slow, making it difficult to meet the needs of large-scale production; water cooling, although faster, consumes a large amount of water resources, and wastewater treatment is costly and may pollute the environment; air cooling equipment has a complex structure, high energy consumption, and its cooling effect is greatly affected by factors such as ambient temperature and wind speed, making it difficult to ensure uniform asphalt cooling. While tubular radiators are widely used due to their high cooling efficiency, existing coolants often discharge from the unit before being fully utilized, resulting in low coolant utilization. Utility Model Content

[0003] The purpose of this invention is to provide an asphalt cooler to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an asphalt cooler, comprising a shell, a heat exchanger, and a return flow member. The shell forms an installation space for the heat exchanger, and the heat exchanger forms a second conveying channel for conveying asphalt along a second preset path.

The inlet end of the three-way pipe communicates with the interior of the installation space, and the two outlet ends of the three-way pipe are respectively fixedly connected to a drain pipe and a guide pipe. A first conveying channel for conveying coolant along a first preset path is formed between the shell, the three-way pipe, and the drain pipe. A third conveying channel for conveying coolant along a third preset path is formed between the shell, the three-way pipe, and the guide pipe. The second conveying channel is not connected to the first conveying channel, and heat exchange occurs between the first and second conveying channels. A valve is installed on the three-way pipe.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1-5 As shown, this utility model provides the following technical solution:

[0022] An asphalt cooler includes a shell 1, a heat exchanger 3, and a return flow member 2. The shell 1 has an internal space for installing the heat exchanger 3, and the heat exchanger 3 has an internal second conveying channel for conveying asphalt along a second preset path. The return flow member 2 is installed on the outside of the shell 1. The return flow member 2 includes a three-way pipe 21 fixedly connected to the shell 1. The inlet end of the three-way pipe 21 communicates with the internal space, and the two outlet ends of the three-way pipe 21 are respectively fixedly connected to a drain pipe 22 and a guide pipe 24. A first conveying channel for conveying coolant along a first preset path is formed between the shell 1, the three-way pipe 21, and the drain pipe 22. A third conveying channel for conveying coolant along a third preset path is formed between the shell 1, the three-way pipe 21, and the guide pipe 24. The second conveying channel is not connected to the first conveying channel, but heat exchange occurs between the first and second conveying channels. A valve 23 is installed on the three-way pipe 21.

[0023] With the above technical solution, when personnel need to dissipate heat from the asphalt, the asphalt conveying pipe is connected to the housing 1, and then the coolant conveying pipe is connected to the housing 1. After the device is prepared, valve 23 is pulled to open the first conveying channel and close the third conveying channel. The coolant flows along the first conveying channel inside the housing 1, and the asphalt flows along the second conveying channel inside the housing 1. Heat exchange occurs between the coolant and the asphalt, thereby reducing the temperature of the asphalt. To improve the utilization rate of the coolant and prevent it from being discharged before it is fully used, valve 23 is pulled to open the first conveying channel and close the third conveying channel. When the coolant flows to the bottom of the housing 1, it enters through the three-way pipe 21 and then flows back into the housing 1 through the guide pipe 24, allowing the coolant to circulate inside the housing 1, thereby improving the utilization rate of the coolant. When personnel need to discharge the coolant, valve 23 is pulled to open the first conveying channel and close the third conveying channel. When the coolant flows to the bottom of the housing 1, it is discharged through the three-way pipe 21, allowing the coolant to be discharged from the first conveying channel.

[0024] Specifically, in one embodiment, regarding the aforementioned housing member 1, as... Figures 1-3 As shown, the shell component 1 includes a tank body 11, with a top cover 14 and a bottom cover 16 fixedly connected to the top and bottom of the tank body 11, respectively. An inner cavity 15 is formed inside the tank body 11, and the heat exchange component 3 is installed inside the inner cavity 15. The liquid inlet end of the three-way pipe 21 is fixedly connected to the tank body 11. A liquid inlet pipe 12 is fixedly connected to one side of the tank body 11. A feed pipe 13 is fixedly connected to the bottom of the top cover 14, and a discharge pipe 17 is fixedly connected to the bottom of the bottom cover 16.

[0025] In this embodiment, the feed pipe 13 is connected to the asphalt conveying pipe, and the coolant conveying pipe is connected to the inlet pipe 12. The asphalt is conveyed into the tank 11 through the feed pipe 13. After entering the tank 11, the asphalt is conveyed to the heat exchanger 3. The coolant is conveyed into the tank 11 through the inlet pipe 12. The coolant exchanges heat with the asphalt inside the heat exchanger 3, thereby reducing the temperature of the asphalt. The cooled asphalt is discharged through the discharge pipe 17. After the coolant exchanges heat with the asphalt, the valve 23 on the three-way pipe 21 is pulled to connect the corresponding drain pipe 22 on the three-way pipe 21, and then the coolant is discharged through the drain pipe 22. When the coolant needs to circulate, the valve 23 is pulled to make the corresponding guide pipe 24 of the three-way pipe 21 flow, and the coolant is discharged through the three-way pipe 21. The coolant flows into the guide pipe 24 and is then conveyed back into the tank 11 through the guide pipe 24, thereby circulating the coolant and improving the coolant utilization rate.

[0026] After the guide pipe 24 delivers the coolant into the tank 11, to prevent the coolant from flowing through the guide pipe 24 towards the tee pipe 21, such as... Figure 1 and Figure 3 As shown, a one-way valve 25 is fixedly connected to the liquid outlet end of the guide pipe 24. The liquid outlet end of the one-way valve 25 is fixedly connected to the tank body 11, and the one-way valve 25 is located above the three-way pipe 21.

[0027] In this embodiment, when the coolant is discharged from the guide pipe 24, the one-way valve 25 is used to ensure that the coolant in the guide pipe 24 can only flow in one direction, thereby preventing the coolant from flowing back and improving the coolant delivery efficiency.

[0028] Specifically, in one embodiment, regarding the heat exchanger 3 described above, as... Figures 3-5 As shown, the heat exchanger 3 includes two end plates 31, and multiple heat exchange tubes 32 are fixedly connected between the two end plates 31. Multiple through holes 33 are formed in the two end plates 31. The through holes 33 communicate with the heat exchange tubes 32, and the through holes 33 are matched with the heat exchange tubes 32 one by one.

[0029] In this embodiment, after the asphalt is delivered into the tank 11, it flows to one side of the end plate 31. Through the through hole 33 on one side of the end plate 31, the asphalt flows into the heat exchange tube 32. When the coolant is delivered into the tank 11, it exchanges heat with the asphalt inside the heat exchange tube 32, thereby assisting in the cooling of the asphalt.

[0030] When the asphalt flows into the heat exchange tube 32, in order to increase the heat exchange area of ​​the asphalt, such as... Figures 3-5 As shown, each heat exchange tube 32 has a heat-conducting plate 34 fixedly connected inside.

[0031] In this embodiment, when the asphalt flows into the heat exchange tube 32, it is combined with the heat conduction plate 34 to increase the heat exchange area of ​​the asphalt, thereby improving the heat dissipation efficiency of the asphalt.

[0032] Furthermore, in this invention, in order to further improve the cooling efficiency of asphalt, such as... Figures 4-5 As shown, multiple through-holes 35 are formed on the heat-conducting plate 34 along its own length direction.

[0033] In this embodiment, the contact area between the asphalt and the heat-conducting plate 34 is increased by using the guide hole 35, thereby further improving the heat dissipation efficiency of the asphalt.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
