Detailed Implementation

[0026] The preferred embodiments of this utility model are described in detail below, and a clear and complete explanation is given in conjunction with the accompanying drawings.

[0027] Please see Figure 1-5 This utility model provides a spiral oil scraping device, including an oil collection tank 100. The upper end of the oil collection tank 100 is equipped with a floating oil cleaning structure 200 for scraping the oil in the oil collection tank 100. The oil collection tank 100 includes a wastewater tank 110. Inside the wastewater tank 110 are a first conveying cylinder 120 and a second conveying cylinder 150 for facilitating the conveying of oil blocks. The right side of the second conveying cylinder 150 and the first conveying cylinder 120 are connected.

[0028] A wastewater conveying pipe 111 for conveying catering wastewater into the wastewater tank 110 is fixedly installed on the upper left side of the wastewater tank 110. The catering wastewater is conveyed into the wastewater tank 110 through the wastewater conveying pipe 111 and undergoes oil-water separation in the wastewater tank 110. A vertical plate for dividing the inner cavity of the wastewater tank 110 is installed on the right side of the wastewater tank 110, and the catering wastewater is located at the left end of the vertical plate. The floating oil cleaning structure 200 is installed on the left side of the vertical plate. The conveyor cylinder 120 is inclined, with its right side higher than its left side. The right side of the conveyor cylinder 120 is also higher than the level of the catering wastewater. An opening is provided on the left side of the conveyor cylinder 120 to facilitate the entry of oil blocks into the conveyor cylinder 120. A screw conveyor 121 for conveying the oil blocks is installed inside the conveyor cylinder 120. A geared motor 122 for controlling the rotation of the screw conveyor 121 is installed at one end of the screw conveyor 121. The central shaft of the screw conveyor 121 is installed at the output end of the geared motor 122. When the geared motor 122 is started, it synchronously drives the screw conveyor 121 to rotate, causing the screw conveyor 121 to convey the oil blocks in the conveyor cylinder 120 to the upper right. An opening is provided at the lower right side of the conveyor cylinder 120 to facilitate the oil blocks falling into the conveyor cylinder 150.

[0029] The wastewater tank 110 is equipped with lead screws 130 at both the front and rear ends for guiding the oil spill cleaning structure 200. A bevel gear 131 is fixedly installed at the right end of the lead screws 130. The right end of bevel gear 131 meshes with bevel gear 140. A rotating rod 141 for controlling the rotation of bevel gear 140 is installed in the middle of bevel gear 140. There are two bevel gears 140, installed at the front and rear ends of the rotating rod 141 respectively. A reduction motor 142 for controlling the rotation of the rotating rod 141 is installed at the front end of the rotating rod 141. The rotating rod 141 is installed at the output end of bevel gear 140, so that after the reduction motor 142 starts, it synchronously drives the rotating rod 141 to rotate. The two bevel gears 140 rotate synchronously, and the two bevel gears 140, in turn, cooperate with the two bevel gears 131 to control the two lead screws 130 to rotate synchronously, causing the oil-scraping structure 200 to move to the left, scraping away the oil stains adhering to the inner wall of the wastewater tank 110.

[0030] The upper end of conveyor cylinder 2 150 is connected to the lower right side of conveyor cylinder 1 120. An oil outlet 151 for discharging oil blocks is installed at the lower right side of conveyor cylinder 2 150. A collection box can be placed below the oil outlet 151 to collect waste oil blocks. Inside conveyor cylinder 2 150 is a screw conveyor 2 152 for conveying oil blocks. A geared motor 3 153 for controlling the rotation of screw conveyor 2 152 is installed in the middle of screw conveyor 2 152. The central shaft of screw conveyor 2 152 is installed at the output end of geared motor 3 153. After geared motor 3 153 starts, screw conveyor 2 152 rotates inside conveyor cylinder 2 150, causing oil blocks falling into conveyor cylinder 2 150 to be conveyed downwards and to the left and right of screw conveyor 2 152 and squeezed out through oil outlet 151.

[0031] The oil spill cleaning structure 200 includes a scraper 210 for condensing oil spill into clumps. As the scraper 210 moves, it simultaneously scrapes away oil adhering to the inner wall of the wastewater tank 110. A top rod 211 is bolted to the upper end of the scraper 210. Screw nuts 212 are fixed to the front and rear ends of the top rod 211 to control the left and right movement of the scraper 210 in conjunction with a screw 130. The screw nuts 212 are fitted onto the screw 130, so that when the screw 130 rotates, the screw nuts 212 drive the top rod 211 to move left and right, facilitating the synchronous left and right movement of the scraper 210. A condensation box 213 is installed at the upper middle part of the top rod 211. A first conveying pipe 214 is installed at the rear end of the condensation box 213, and a second conveying pipe 215 is installed at the front end of the condensation box 213.

[0032] Multiple partition plates 216 for separating oil blocks are fixedly installed at equal intervals on the lower left side of the scraper 210. When catering wastewater is added into the wastewater tank 110, the water level of the wastewater is higher than the bottom of the partition plate 216 and lower than the top of the partition plate 216. Multiple pressure plates 217 for pushing oil blocks are installed on the left end of the scraper 210, and the pressure plates 217 are located at the upper end between adjacent partition plates 216. A connecting frame 218 for limiting the multiple pressure plates 217 is fixedly installed on the upper end of the pressure plates 217. An electric push rod 219 for controlling the up and down movement of the pressure plates 217 is installed on the upper middle part of the connecting frame 218. A fixing block for limiting the electric push rod 219 is fixedly installed on the upper left side of the wastewater tank 110. After the electric push rod 219 is started, the connecting frame 218 synchronously controls the multiple pressure plates 217 to move downward, so that the oil blocks between the pressure plates 217 and adjacent partition plates 216 are pushed downward.

[0033] The scraper 210 has a conveying pipe 3 10 installed inside, and the rear end of the conveying pipe 3 10 is connected to the conveying pipe 1 214. The rear end of the conveying pipe 3 10 is connected to the lower end of the conveying pipe 1 214 via a flange, and the front end of the conveying pipe 3 10 is connected to the conveying pipe 2 215 via a flange. The front end of the conveying pipe 3 10 is connected to the lower end of the conveying pipe 2 215 via a flange. Multiple connecting pipes 11 are installed at the lower end of the conveying pipe 3 10. The connecting pipes 11 are U-shaped pipes and are installed inside the partition plate 216 to facilitate the coagulation of oil stains on both sides of the partition plate 216. The upper end of connecting pipe 11 is connected to conveying pipe four 12, and conveying pipe four 12 is connected to the front end of conveying pipe three 10. A pump for conveying refrigerant is installed inside the condenser 213. The refrigerant in the condenser 213 is conveyed to conveying pipe three 10 via conveying pipe one 214. A portion of the refrigerant is then conveyed from the rear end to the front end of conveying pipe three 10, while another portion is conveyed to conveying pipe four 12 via multiple connecting pipes 11, and then conveyed to the front end of conveying pipe three 10 via conveying pipe four 12. Finally, it is conveyed to the interior of the condenser 213 via conveying pipe two 215. When the refrigerant inside conveying pipe three 10 flows to the lower end of scraper 210, it accelerates the coagulation of oil on the left side of scraper 210.

[0034] After the catering wastewater is transported into the wastewater tank 110, the starting of the second geared motor 142 causes the rotating rod 141 to drive the two bevel gears 140 to rotate synchronously. The two lead screws 130 work in sync with the lead screw nut 212 to control the scraper 210 to move left and right. When the scraper 210 moves, it not only scrapes off the oil stains on the inner wall of the wastewater tank 110, but also causes the oil stains on the left side of the scraper 210 to quickly solidify into blocks under the action of the third conveying pipe 10 and the connecting pipe 11. The starting of the electric push rod 219 pushes the solidified oil blocks downward, causing the oil blocks to fall to the lower end of the first conveying cylinder 120. The rotation of the screw conveyor 121 controlled by the first geared motor 122 transports the oil blocks to the right side of the first conveying cylinder 120 and into the second conveying cylinder 150. Finally, the screw conveyor 152 squeezes the oil blocks out of the oil outlet 151.
