Abstract
Description
Technical Field
[0001] This utility model relates to the field of modified asphalt processing technology, and in particular to a temperature control device for modified asphalt processing. Background Technology
[0002] Modified asphalt is an asphalt mixture produced by adding external admixtures (modifiers) such as rubber, resin, polymer, finely ground rubber powder, or other fillers, or by taking measures such as slight oxidation processing of asphalt to improve the properties of asphalt or its mixtures. In the processing of modified asphalt, it is often necessary to heat the asphalt to a certain temperature and then mix it with other mixtures to produce modified asphalt. However, existing production mixing facilities for modified asphalt use electric heating or fire methods to heat the asphalt to a suitable temperature for mixing, which cannot control the temperature well. During the mixing process, temperature differences can easily occur, resulting in inconsistent asphalt production quality. Therefore, this application proposes a temperature control device for modified asphalt processing. Utility Model Content

[0030] Example 1
[0031] like Figure 1 - Figure 5 As shown, the present invention proposes a temperature control device for modified asphalt processing, including a box 1 and a heating mechanism 2 and a cooling mechanism 4 disposed on one side of the box 1. By setting the heating mechanism 2 and the cooling mechanism 4, the device can regulate the temperature inside the inner box 14.
[0032] like Figure 1 - Figure 5As shown, the heating mechanism 2 includes a heating tank 21, with an oil guide pipe 22 penetrating the bottom of the outer wall of the heating tank 21. An electric heating structure is provided on the inner wall of the heating tank 21, and a transmission structure is provided at the end of the oil guide pipe 22 away from the heating tank 21. The heating tube 28 is heated by the electric heating terminal 29 in the electric heating mechanism, which in turn heats the heat-conducting oil in the heating tank 21. The heat-conducting oil is then transferred to the outer wall of the inner tank 14 via the transmission mechanism to heat the asphalt inside the inner tank 14.
[0033] like Figure 2 and Figure 4 As shown, the cooling mechanism 4 includes a cold oil storage tank 41. A cold oil transmission pipe 42 is fixedly connected to one side of the outer wall of the cold oil storage tank 41. A circulating cooling mechanism is provided at the end of the cold oil transmission pipe 42 away from the cold oil storage tank 41. The circulating cooling mechanism is located on the inner bottom end face of the box 1. Through the cold oil transmission pipe 42, the cold heat transfer oil is transferred to the heat conduction pipe 45 at the bottom of the inner box 14. The heat conduction pipe 45 absorbs the heat inside the inner box 14, thereby reducing the temperature inside the box 1 and thus regulating the temperature.
[0034] In this embodiment, the device heats the heat transfer oil in the heating tank 21 to a certain temperature through the heating pipe 28, and then transfers the heat transfer oil to the heat transfer coil 25 through the transfer pump 23. The heat transfer coil 25 evenly distributes the heat to the asphalt, preventing uneven heating of the asphalt and affecting the mixing production speed. The pump in the cold oil storage tank 41 transfers the cold heat transfer oil to the cold oil transfer pipe 42, and then transfers the cold heat transfer oil to the heat dissipation plate 44 located at the bottom of the inner box 14. Through the multiple heat transfer pipes 45 in the heat dissipation plate 44, the heat in the inner box 14 can be absorbed when the temperature is too high, so that the temperature of asphalt production can be better controlled. Compared with the traditional method of asphalt temperature control and waiting for cooling, it is more efficient and has a better effect.

[0037] With the above configuration, by setting the heating terminal 29 and the heating tube 28, the device can heat the heat transfer oil in the heating tank 21, so that the heat transfer oil can be transferred to the box 1 to heat the inner box 14.
[0038] The transmission mechanism includes a transmission pump 23 fixedly connected to the oil guide pipe 22.

The hot heat-conducting oil is transferred to the heat-conducting coils 25 through the transmission pipe 24. The heat-conducting coils 25 heat the inner tank 14. The cooled hot heat-conducting oil is transferred back to the heating tank 21 through the return pipe 26 for circulating heating.
[0039] The circulating cooling mechanism includes a heat-conducting pipe 45 fixed to one end of the cold oil transmission pipe 42.

The cold heat-conducting oil that has absorbed heat is transferred back to the cold oil storage tank 41 for cooling through the cold oil return pipe 43, so that the temperature of the inner housing 14 can be reduced to achieve the purpose of operating temperature.
[0040] Multiple hooks 11 are fixedly connected to the inner wall of the box 1. An insulation layer 12 is hung on the end of the multiple hooks 11 away from the box 1. Two connecting blocks 13 are fixedly connected to both sides of the inner wall of the box 1. An inner box 14 is fixedly connected to the end of the multiple connecting blocks 13 away from the box 1. The insulation layer 12 prevents the temperature of the inner box 14 from being lost. The insulation layer 12 is fixed by the hooks 11.
[0041] The top of the inner box 14 is provided with a drive mechanism 3. The drive mechanism 3 includes a drive motor 31 fixed to the top of the inner box 14.
