Description

Technical Field

[0001] The present invention relates to the technical field of oil residue separation equipment, and more specifically, to an oil residue separation scraper conveying device. Background Art

[0002] After animal raw materials are refined in a refining cylinder, an oil residue separation operation needs to be carried out. The common method is to use an oil residue separation scraper conveyor to convey the refined oil residue mixture. During the conveying process, an oil filter plate on the scraper conveyor is used to filter and separate the oil and residue in it. Since the scraper conveyor itself does not have a pressing function, the residue after filtration still has a high oil content. Therefore, it is necessary to convey the residue after filtration to a pressing device for further pressing operation, which not only increases the equipment cost, but also increases the process flow and reduces the production efficiency.

DETAILED DESCRIPTION OF THE INVENTION

[0035] Next, a clear and complete description of the specific implementation manners of the present invention will be given in conjunction with the accompanying drawings of the specification.

[0036] As shown Figures 1-8 in the figure, a dregs separation scraper conveyor device includes a housing 10 and a conveying trough 20. The conveying trough 20 includes two oppositely arranged side plates 21. A filter plate 22 is arranged between the two side plates 21. One end of the conveying trough 20 is set as the feeding end, and the other end is set as the discharging end.

[0037] The housing 10 is arranged outside the conveying trough 20. By fixedly connecting a number of support rods 14 between the side plate 21 and the housing 10, the conveying trough 20 can be supported in the housing 10. The housing 10 is provided with a feeding hopper 11, an oil hopper 12 and a dregs outlet 13. The feeding hopper 11 is located above the feeding end of the conveying trough 20. The oil hopper 12 is arranged at the bottom of the housing 10 and is located below the conveying trough 20. The dregs outlet 13 corresponds to the discharging end of the conveying trough 20.

[0038] A driving shaft 24 is rotatably connected to the discharging end of the conveying trough 20. A first driving sprocket 241 and a second driving sprocket 242 are fixedly connected to the driving shaft 24. A driving motor 23 is fixedly arranged on one of the side plates 21 of the conveying trough 20. The driving motor 23 is in transmission connection with one end of the driving shaft 24. A driven shaft 25 is rotatably connected to the feeding end of the conveying trough 20. A first driven sprocket 251 and a second driven sprocket 252 are fixedly connected to the driven shaft 25. A first chain 26 is connected between the first driving sprocket 241 and the first driven sprocket 251. A second chain 27 is connected between the second driving sprocket 242 and the second driven sprocket 252. The first chain 26 and the second chain 27 are respectively arranged around the filter plate 22. The first chain 26 and the second chain 27 can be driven to rotate synchronously by the driving motor 23.

[0039] A number of scrapers 28 are fixedly connected between the first chain 26 and the second chain 27. The scrapers 28 move as the first chain 26 and the second chain 27 rotate, and can push the materials on the filter plate 22 from the feeding end of the conveying trough 20 to the discharging end.

[0040] A first sliding rod 261 and a second sliding rod 271 are arranged between every two adjacent scrapers 28. The first sliding rod 261 is slidably connected to the first chain 26. The second sliding rod 271 is slidably connected to the second chain 27. The inner end of the first sliding rod 261 is fixedly connected with a first pressing plate 262, and the outer end is rotatably connected with a first roller 263. The inner end of the second sliding rod 271 is fixedly connected with a second pressing plate 272, and the outer end is rotatably connected with a second roller 273.

[0041] A first spring 264 is provided between the first sliding rod 261 and the first chain 26. The first spring 264 presses the first sliding rod 261 outwards. A second spring 274 is provided between the second sliding rod 271 and the second chain 27. The second spring 274 presses the second sliding rod 271 outwards. By using the first spring 264 and the second spring 274, the first roller 263 and the second roller 273 can always press against the inner side wall of the housing 10 during the movement process.

[0042] Circular tracks 16 are respectively provided on the inner side wall of the housing 10 corresponding to the movement paths of the first roller 263 and the second roller 273. And convex portions 15 are respectively fixedly provided on the movement paths of the first roller 263 and the second roller 273. When the first sliding rod 261 and the second sliding rod 271 move to the positions of the convex portions 15, under the limiting action of the convex portions 15, the first sliding rod 261 and the second sliding rod 271 slide inwards synchronously, and the first pressing plate 262 and the second pressing plate 272 approach each other, and the oil residue mixed material between the first pressing plate 262 and the second pressing plate 272 can be automatically squeezed. Among them, the squeezed oil falls downwards through the filter plate 22 into the oil hopper 12, and the slag is continuously pushed towards the slag outlet 13 by the scraper 28. When the first sliding rod 261 and the second sliding rod 271 leave the positions of the convex portions 15, the first pressing plate 262 and the second pressing plate 272 automatically separate under the elastic action.

[0043] Furthermore, the structure of the filter plate 22 includes a plurality of grid plates 221 arranged at intervals. The length direction of the grid plates 221 is parallel to the movement path of the scraper 28. The plurality of grid plates 221 are fixedly connected in series through a connecting plate 222 below them. A plurality of picking claws 281 are fixedly connected to the scraper 28. The picking claws 281 are slidably arranged in the gaps between the plurality of grid plates 221. During the movement of the scraper 28, the picking claws 281 can scrape off the materials blocked in the gaps between the grid plates 221, so that the filter plate 22 can maintain a good effect of separating oil and slag.

[0044] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed.
