Technical Field

[0001] The utility model relates to the technical field of grease recovery, in particular to a solid grease unloading device. Background Art

[0002] In the biodiesel industry, in addition to slop oil, gutter oil, oil residue, acidified oil and other oils that are liquid at room temperature, there are also oils that are solid at room temperature. At present, after solid oils are loaded in containers and transported to factories at home and abroad, they are unloaded by excavators directly or by moving the containers into a heating room to heat them up so that all the oils are melted before being put into the oil pool.

[0003] In fact, in order to make the grease reach a state that is convenient for pipeline transportation, it is not necessary to completely melt the grease, but only to soften it into a molten state. However, due to the large size of the container, the temperature of the grease in the entire container increases from the outside to the inside. When the grease in the center reaches the molten state, the grease on the outer layer has completely melted. Excessive heating of the outer layer of grease leads to high energy consumption. Utility Model Content

[0004] In view of this, it is necessary to provide a solid grease unloading device to solve the technical problem in the prior art that the energy consumption of heating the solid grease is very high in order to facilitate unloading.

[0019] Figure 2 for Figure 1 Enlarged view of point A in the middle. DETAILED DESCRIPTION

[0020] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings, wherein the accompanying drawings constitute a part of the present application and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not used to limit the scope of the present invention.

[0021] See also Figure 1 The utility model provides a solid grease unloading device. The solid grease unloading device can be applied to the production of biodiesel to unload solid grease.

[0022] It should be noted that the solid grease unloading device of the present invention is used in, but not limited to, the production of biodiesel, and can also be applied to other scenarios where heating is required to soften materials so that the materials can be transported through pipelines. In the present invention, only the application of the solid grease unloading device in the production of biodiesel is used as an example for explanation, and the principles of application in other similar scenarios are substantially the same as those of application in the production of biodiesel, and are not described one by one here.

[0023] The solid grease is loaded in a box, which is usually a standard container 10. The box has a discharge port 11. In the prior art, after the solid grease in the whole box is heated and melted, all the grease is discharged through the discharge port 11.

[0024] The solid grease unloading device includes a connecting pipe 2, an oil pipeline 3 and a heater 4. One end of the connecting pipe 2 is detachably connected to the discharge port 11, and the other end is connected to the oil storage device 50 through the oil pipeline 3. The oil storage device 50 can be an oil storage tank, an oil storage pool or other equipment. The heater 4 is fixedly connected to the connecting pipe 2 and inserted into the solid grease through the discharge port 11 to heat and soften the solid grease. By heating the solid grease inside, a part of the grease is softened by heat and discharged through the connecting pipe 2, and does not continue to stay in the container 10 to absorb heat. In this way, the heating energy consumption during unloading can be greatly reduced, and the unloading cost can be reduced.

[0025] In some embodiments, the connecting pipe 2 has three interfaces, the first interface 21 is detachably connected to the discharge port 11, the second interface 22 is connected to the oil pipeline 3, and the third interface 22 is closed. The heater 4 passes through the first interface 21 and the third interface 23.

[0026] See also Figure 2 In a preferred embodiment, the first interface 21 has a quick-release connector 6 for connecting to the discharge port 11 for quick connection and disassembly.

[0027] And the second interface 22 is preferably arranged below the first interface 21 to facilitate the outflow of grease.

[0028] In some embodiments, a glass viewing tube 7 is provided near the second interface 22 of the oil pipeline 3 to observe the flow of grease inside the oil pipeline 3 so as to timely know the time point when the grease starts to flow out and is completely unloaded.

[0029] In other embodiments, a screw pump 8 is further arranged on the oil pipeline 3 , and the screw pump 8 is used to drive the oil to flow to the oil storage device 50 .

[0030] In some embodiments, the heater 4 is a hard air pipe, and the portion of the heater 4 located outside the first interface 21 is formed with a plurality of air outlets, and the portion of the heater 4 located outside the third interface 23 is used to connect a steam generating device. Solid grease is very soft, and the hard air pipe can be easily inserted into the solid grease. High-temperature steam is ejected from the air outlet of the hard air pipe, heating the grease and softening it to facilitate flow. After the softened grease flows out, the high-temperature steam continues to spray and heat the still solid grease, and this process is repeated until all the grease enters the oil storage device 50 through the oil pipeline 3.

[0031] In other embodiments, the heater 4 may also be an electric heater, and the portion of the heater 4 outside the third interface 23 is used to connect to an external power source. The way in which the electric heater heats and softens the solid grease is similar to steam heating, and will not be described in detail.

[0032] In some embodiments, the outer diameter of the heater 4 is smaller than the inner diameter of the connecting pipe 2, and a space for grease to pass through is formed between the heater 4 and the connecting pipe 2. For example, in this embodiment, the outer diameter of the heater 4 is 20 mm, and the inner diameter of the connecting pipe 2 is 65 mm.

[0033] Compared with the prior art, the solid oil unloading device provided by the utility model inserts the heater into the solid oil through the unloading port, directly heats the inside of the solid oil, and a part of the oil is softened by the heat and discharged through the connecting pipe without continuing to stay in the container to absorb heat. In this way, the heating energy consumption during unloading can be greatly reduced, thereby reducing the unloading cost.

[0034] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by any technician familiar with the technical field within the technical scope disclosed in the present invention should be included in the protection scope of the present invention.
