[0019] Example 1

[0020] Combined with attachment Figure 1 This embodiment proposes a melting device, including a pre-melting tank 9 and a melt tank 11. The melt tank 11 is located at the lower side of the pre-melting tank 9. The top and bottom of the pre-melting tank 9 are respectively provided with a feed port 2 and a discharge port 18. The top opening of the melt tank 11 is connected to the discharge port 18, and the bottom of the melt tank 11 is provided with a material outlet 19; a heating jacket 10 is provided on the outside of the pre-melting tank 9, and a heating layer is formed between the heating jacket 10 and the outer wall of the pre-melting tank 9. The heating jacket 10 is provided with a heat source inlet 5 and a heat source outlet 8 connected to the heating layer. A heating elbow 4 is coiled in the pre-melting tank 9, and both ends of the heating elbow 4 are connected to the heating layer.

[0021] In a melting device of this embodiment, a heating jacket 10 is provided outside the pre-melting groove 9, forming a heating layer between the jacket and the outer wall of the pre-melting groove 9, thereby fully heating the material near the groove wall of the pre-melting groove 9. At the same time, a heating elbow 4 is also provided in this embodiment, which is connected to the heating layer, so that the material inside the pre-melting groove 9 can be heated through the heating elbow 4. Therefore, the combination of the heating jacket 10 and the heating elbow 4 increases the heated area of the material, reduces the melting time, and improves the melting efficiency.

[0022] The melting equipment of this embodiment operates as follows: Materials such as DCP or a melting aid are added to the pre-melting tank 9 through a feed port 2 located at the top of the pre-melting tank 9. Simultaneously, a heat source medium such as hot water enters the heating layer and heating elbow 4 through a heat source inlet 5 on a heating jacket 10 and is ultimately discharged through a heat source outlet 8. As the heat source medium flows through the heating layer and heating elbow 4, it fully heats and melts the DCP and other materials in the center and near the outer wall of the pre-melting tank 9. The melted materials then flow through a discharge port 18 into a melt tank 11 for collection.

[0023] In one embodiment, the height of the heat source inlet 5 is set to be lower than the height of the heat source outlet 8, so that the heat source medium such as hot water flows from low to high in the heating layer, thereby slowing down the flow rate to achieve sufficient heating of the material close to the groove wall of the pre-melting groove 9.

[0024] Similarly, in a further embodiment, one end of the heating elbow 4 is connected to the heating layer near the heat source inlet 5, and the other end of the heating elbow 4 is connected to the heating layer near the heat source outlet 8. As a result, the heat source medium flowing through the heating elbow 4 inside the pre-melting tank 9 will also flow from the lower part to the higher part, thereby fully heating the material in the pre-melting tank 9.

[0025] In other embodiments, the present invention further includes a motor 1 and a stirring screw 3. The motor 1 is fixed to the top of the pre-melting tank 9. The output end of the motor 1 is fixedly connected to the stirring screw 3. The stirring screw 3 extends into the pre-melting tank 9. The stirring screw 3 is provided with an impeller 20. Thus, by turning on the motor 1, the stirring screw 3 and the impeller 20 can be driven to rotate, thereby accelerating the melting and fully dispersing the additives, thereby improving the mixing effect of different additives.

[0026] In other embodiments, a pull-out frame 14 is movably provided on the melt tank 11 near the discharge port 18, and a filter screen 7 is provided on the pull-out frame 14. In conventional melting devices, generally only one non-replaceable filter screen 7 is provided to replace the molten material. Due to the accumulation of impurities and temperature changes of the melt, the filter screen 7 is easily clogged. In the present embodiment, the filter screen 7 is movably provided on the melt tank 11 through the pull-out frame 14. When the filter screen 7 is clogged, the pull-out frame 14 can be directly pulled out and the filter screen 7 can be replaced to continue working, which greatly improves practicality. In the present embodiment, the filter screen 7 is generally preferably a high-mesh filter screen 7.

[0027] On the basis of the above embodiment, a handle 15 may be provided on the drawer frame 14 to facilitate user operation and further improve the convenience of use.

[0028] In this embodiment, the material flowing into the melt tank 11 is ultimately supplied to the outside through the material outlet 19. To further ensure the cleanliness of the molten material, in one embodiment, a filter element 12 is provided at the connection between the material outlet 19 and the melt tank 11. This filter element 12 filters impurities, ensuring that the material supplied from the material outlet 19 to the outside has a relatively high degree of cleanliness. Furthermore, the filter screen 7 of the aforementioned embodiment can be combined with the filter element 12 of this embodiment to achieve a dual filtration effect, further ensuring the cleanliness of the material.

[0029] In addition, similar to the principle of the heating layer, an insulation jacket 21 can also be provided on the outside of the melt tank 11. The insulation jacket 21 forms an insulation layer between the insulation jacket 21 and the outer wall of the melt tank 11. The insulation jacket 21 is provided with an insulation source inlet 16 and an insulation source outlet 17 that are connected to the insulation layer. As a result, an insulation medium such as hot water can flow into the insulation layer from the insulation source inlet 16 and eventually flow out from the insulation source outlet 17. During the flow of the insulation medium, the heat of the material can be maintained, thereby ensuring that the material remains in a molten state.

[0030] In a further embodiment, the height of the heat insulation source inlet 16 can also be set to be lower than the height of the heat insulation source outlet 17. Similar to the situation in the aforementioned embodiment where the height of the heat source inlet 5 is lower than the heat source outlet 8, this embodiment can allow the heat insulation medium such as hot water to flow from a low point to a high point in the heat insulation layer, thereby slowing down the flow rate, thereby achieving sufficient heat insulation of the material close to the tank wall of the melt tank 11.

[0031] Furthermore, in a conceivable embodiment, a first valve 6 is provided at the material outlet 18 and a second valve 13 is provided at the material outlet 19, thereby controlling the flow of the material.

[0032] The above schematically describes the present invention and its embodiments, which are not restrictive. The accompanying drawings only illustrate one embodiment of the present invention, and the actual structure is not limited thereto. Therefore, if a person skilled in the art is inspired by the above and, without departing from the inventive purpose of the present invention, designs structures and embodiments similar to the technical solution without creatively designing them, they shall fall within the scope of protection of the present invention.
