Description

Technical Field

[0001] The utility model relates to the technical field of kitchen waste recycling, and specifically relates to an oil recovery device for rough sorting materials of kitchen waste. Background Technique

[0002] The oil recovery device for rough sorting materials of kitchen waste effectively separates and recovers the oil in the kitchen waste through specific technologies and processes. The recovered oil can be used in various fields such as biodiesel and chemical raw materials, realizing the recycling of resources and reducing the environmental pollution caused by oil at the same time.

[0003] There is an existing oil recovery device for rough sorting materials of kitchen waste with the Chinese patent application number 202320048784.X, which includes a frame, a material pressing box, a static settling box and a material pressing assembly; the top of the material pressing box is open, a discharge port is arranged on one side of the material pressing box, a filter plate is arranged in the material pressing box, and the filter plate divides the inner cavity of the material pressing box into an upper extrusion cavity and a lower filtering cavity; the inner cavity of the static settling box is communicated with the filtering cavity, a drain pipe is connected to the bottom end of the static settling box, and an oil suction pipe is connected to the top end of the static settling box. By adopting the above technical solution, the kitchen waste is added into the material pressing box, the material pressing assembly is adjusted to extrude the kitchen waste in the box, the oil and water contained in it are extruded out and filtered by the filter plate, and finally flow into the static settling box. After standing until the oil and water are separated, the oil is discharged through the upper oil suction pipe, and the water is discharged through the lower drain pipe, so as to realize the recovery of oil in the solid kitchen waste and reduce the waste of oil. However, this device still has some defects.

[0004] This device does not set up a mechanism for preliminary sorting of kitchen waste, resulting in that large foreign objects (such as plastic bags, glass, metal, etc.) and non-kitchen waste (such as paper towels, packaging boxes, etc.) in the kitchen waste may directly enter the oil recovery system. These impurities will not only increase the load of the processing equipment, but also may block components such as pipelines and filter screens, causing the oil recovery efficiency to decline.

[0005] Therefore, we propose an oil recovery device for rough sorting materials of kitchen waste to solve the problems raised above. Content of the Utility Model

[0006] The purpose of the utility model is to provide an oil recovery device for rough sorting materials of kitchen waste to solve the problem that the existing device does not set up a mechanism for preliminary sorting of kitchen waste, resulting in that large foreign objects (such as plastic bags, glass, metal, etc.) and non-kitchen waste (such as paper towels, packaging boxes, etc.) in the kitchen waste may directly enter the oil recovery system. These impurities will not only increase the load of the processing equipment, but also may block components such as pipelines and filter screens, causing the oil recovery efficiency to decline as mentioned in the above background technique.

A chute 6 is opened at the top end inside the box body 1, and a threaded rod 7 is connected to the inside of the chute 6 through a bearing. One end of the threaded rod 7 is connected to a first motor 16, and a threaded sleeve 8 is threadedly connected to the outer surface of the threaded rod 7. The bottom end of the threaded sleeve 8 is fixedly connected to a support frame 9, and a hydraulic cylinder 10 is installed inside the support frame 9. The bottom of the support frame 9 is fixedly connected to a fixed block 11, and the bottom of the fixed block 11 is connected to a connecting rod 12 through a rotating shaft. The bottom end of the hydraulic cylinder 10 is fixedly connected to a connecting block 13.

And a first motor 16 is installed on the outer side of the box body 1. Starting the first motor 16 can drive the threaded rod 7 to rotate. The threaded sleeve 8 threadedly connected to the threaded rod 7 drives the support frame 9 to move. Then, start the hydraulic cylinder 10. When the hydraulic cylinder 10 pushes the connecting block 13 downward, it can drive the connecting rod 12 and the support rod 14 to move toward the middle at the same time, so that the clamping block 15 clamps the large impurities and sends them into the inside of the feed box 5, thus achieving the purpose of preliminary sorting.

[0029] A crushing box 17 is arranged inside the box body 1, and a feed frame 18 is arranged on the top of the crushing box 17.
