[0032] like Figure 3 , Figure 5 and Figure 6As shown, the melting mechanism 2 includes a storage chamber 201, a heat dissipation hole 202, a heating wire 203, a base 204, a support rod 205, a motor 206, a circular plate 207, an extension rod 208, a first connecting member 209, a connecting rod 210, a second connecting member 211, a fixing plate 212 and a support rod 213.

When the extension rod 208 is driven to the lowest point, the bottom of the tank body 1 will fit with the top of the base 204. When the extension rod 208 is gradually brought to the highest point by the circular plate 207, the other end of the connecting rod 210 will gradually move upward. At this time, the angle between the bottom of the tank body 1 and the top of the base 204 will gradually increase, thereby causing the tank body 1 to gradually tilt. Repeating the above steps will cause the melted grease and the unmelted grease inside the tank body 1 to shake continuously, thereby accelerating the heat transfer process inside the grease, allowing the grease to reach a melted state faster, and improving the melting efficiency.

Under the action of gravity and inertia, the recovered oil will open the one-way valve 1205 on the return pipe 1204, thereby allowing the returned oil to enter the tank body 1.

[0035] like Figure 3 and Figure 5 As shown, the blocking assembly 3 includes a rotating rod 301, a cover plate 302, a through hole 303, a first mounting plate 304, a second mounting plate 305 and a bolt 306. The rotating rod 301 is fixedly connected to the top wall of the tank body 1, and the cover plate 302 is rotatably connected to the outside of the rotating rod 301. A through hole 303 matching the air inlet pipe 1202 and the return pipe 1204 is opened on the top of the cover plate 302. The length of the air inlet pipe 1202 and the return pipe 1204 inserted into the through hole 303 is the same as the depth of the through hole 303 and the thickness of the cover plate 302. When the cover plate 302 is opened, the oil vapor filter assembly 1202 will also be driven The first mounting plate 304 and the second mounting plate 305 are respectively fixedly connected to the cover plate 302 and the outer wall of the tank body 1, and the bolts 306 are threadedly connected to the inside of the first mounting plate 304 and the second mounting plate 305. The cover plate 302 can completely cover the top of the tank body 1. The number of through holes 303 is several. When the grease is melted, the grease will shake and the grease may accidentally splash out. At this time, the cover plate 302 can block the top of the tank body 1 to prevent the grease from splashing out. The first mounting plate 304 and the second mounting plate 305 are connected by bolts 306 to prevent the cover plate 302 from moving.

[0036] like Figure 3As shown, an observation hole 4 is provided at the top of the cover plate 302, and a transparent tempered glass plate 5 is obliquely provided inside the observation hole 4. The transparent tempered glass plate 5 is made of a heat-resistant transparent material. When in use, the transparent tempered glass plate 5 and the observation hole 4 can facilitate workers to observe the melting progress of the grease inside the tank body 1 from the outside.

[0037] like Figure 5 As shown, one side of the second mounting plate 305 is fixedly connected to the limiting plate 6, the side wall of the limiting plate 6 is tightly fitted with the side wall of the cover plate 302, and the limiting plate 6 is fixedly connected to the side wall of the tank body 1.

[0040] like Figure 3 As shown, a filter screen 11 is fixedly connected to the inner bottom wall of the tank body 1, and the top of the filter screen 11 is fixedly connected to the inner wall of the tank body 1. The aperture of the filter screen 11 is smaller than the particle size of impurities inside the grease. When discharging the melted grease, the filter screen 11 can filter the impurities to avoid the impurities being discharged together with the grease, thereby improving the cleanliness of the grease.

[0041] Specifically, when the melting device for recycling waste animal and vegetable oil resources is used: the electric heating wire 203 and the motor 206 are connected to an external power source, and then the electric heating wire 203 is electrically connected to an external temperature controller to control the temperature heated by the electric heating wire 203, and then the solid waste animal and vegetable oil is placed inside the tank body 1, and then the cover plate 302 is rotated until the side wall of the cover plate 302 fits with the limit plate 6, and then the first mounting plate 304 is connected to the second mounting plate 305 by bolts 306 to prevent the cover plate 302 from moving, and then the motor 206 and the electric heating wire 203 are started, and the electric heating wire 203 raises the temperature inside the tank body 1 to the specified temperature set by the worker, and then the motor 206 drives the circular plate 207 to rotate, and at this time the connecting rod 2 One end of 10 will be supported by the support rod 213. When the extension rod 208 is driven to the lowest point, the bottom of the tank body 1 will fit with the top of the base 204. When the extension rod 208 is gradually brought to the highest point by the circular plate 207, the other end of the connecting rod 210 will gradually move upward. At this time, the angle between the bottom of the tank body 1 and the top of the base 204 will gradually increase, thereby causing the tank body 1 to gradually tilt. Repeating the above steps will cause the melted grease and the unmelted grease inside the tank body 1 to shake continuously, thereby accelerating the heat transfer process inside the grease, allowing the grease to reach a melted state faster, and improving the melting efficiency. After the grease is melted, open the solenoid valve 10 to facilitate the discharge of the grease inside the tank body 1. The melting of the grease can be achieved through the above steps.

[0042] All technical features in this embodiment can be freely combined according to actual needs.
