Description

Technical Field

[0001] This utility model relates to the field of grease melting technology, specifically a waste grease melting device. Background Technology

[0002] The swill produced by the catering industry contains a lot of grease. If this grease is discharged directly, it will cause environmental pollution. Usually, it is collected and reused, such as in the processing of biodiesel. When recycling waste grease, a melting device is needed to melt the solidified grease.

[0003] An existing waste cooking oil melting device, such as Chinese patent application number CN202322314659.1, includes a processing box. The top of the processing box is rotatably connected to an automatically opening and closing cover. Inside, a barrel rack and a filter plate are horizontally arranged from top to bottom. The barrel rack and filter plate vertically divide the interior of the processing box into an oil barrel placement area, a heating and filtering area, and an oil discharge area. A cleaning door is rotatably embedded on the outer wall of the heating and filtering area. Inside, there are steam coils arranged in a serpentine pattern with both ends extending out of the processing box. An oil discharge port is provided on the lower part of the outer wall of the oil discharge area, and a discharge valve is provided on the oil discharge port. The existing waste cooking oil melting device has a low melting efficiency because the internal heating of the solidified oil is slow. During use, the existing melting device is difficult to heat the internal parts of large pieces of oil, which affects the melting efficiency.

[0004] Therefore, we propose a waste oil melting device to solve the problems mentioned above. Utility Model Content

[0013] By adopting the above technical solution, the design of the filter box and filter screen can further filter the melted grease, facilitating further processing.

[0014] Preferably, the transmission tube is rotatably connected to the positioning shaft, and the outer wall of the transmission tube is fixed to the stirring frame, and the stirring frame is arranged in a ring array with the transmission tube as the center.

[0015] By adopting the above technical solution, the stirring frame connected to the outside of the transmission pipe can be used to stir the solidified grease inside the melting tank during rotation, thereby improving the melting efficiency.

[0019] Using the above technical solution, the rotation of the stirring frame can drive the drive shaft and multiple sets of cutting and stirring blades to rotate around the drive tube. At the same time, by utilizing the cooperation of bevel gears and bevel gear discs, the multiple sets of cutting and stirring blades can rotate simultaneously while the drive shaft revolves around the drive tube, thereby improving the stirring effect. Meanwhile, the cutting and stirring blades can cut large pieces of solidified grease inside during rotation, improving melting efficiency.
