Under continuous pressure, the filter plate 15 will move toward the material box 12. At this time, the oil in the raw material will be discharged from the first oil outlet pipe 14, and the remaining oil residue will remain in the filter plate 15. Then the hydraulic cylinder 17 is contracted to drive the filter plate 15 to reset, and then the oil residue remaining in the filter plate 15 is cleaned up. At this time, the external water source is connected to the first fixed plate 16, and the water pump 1 is started. 15 draws water from the first filter box 116, and then sprays it onto the filter plate 15 through the water outlet pipe 111. At the same time, the linear motor 110 can be started to reciprocate and drive the water outlet pipe 111 to move, so that the filter plate 15 can be rinsed from the top. In this step, a water pump 115 is set to connect the first filter box 116 and the water outlet pipe 111, so that the filter plate 15 can be rinsed after use, and the oil residue particles remaining in the filter plate 15 can be rinsed away. At the same time, the linear motor 110 cooperates with the slider 114 to make the water outlet pipe 111 reciprocate, which can improve the flushing effect of the filter plate 15 and reduce the blockage caused by the oil residue remaining in the filter plate 15.

[0026] like Figure 4As shown, the bottom of the water outlet pipe 111 is connected to a plurality of metal bellows 2; the end of the metal bellows 2 is fixedly connected to a nozzle 21; during operation, when water flows out of the water outlet pipe 111, it will pass through the metal bellows 2, and then enter the nozzle 21 to be sprayed onto the filter plate 15. At this time, the nozzle 21 can disperse the water flow to increase the spraying range of the water. At the same time, the bendable design of the metal bellows 2 can change the spraying direction of the nozzle 21, and can be used for targeted flushing of areas with more residual oil residue. In this step, by setting a metal bellows 2 to connect the nozzle 21 and the water outlet pipe 111, the water flow can be dispersed to increase the spraying range of the water flow, so as to improve the uniformity of flushing the filter plate 15. At the same time, the metal bellows 2 drives the nozzle 21 to change the spraying direction to adapt to the area with dense residual oil residue on the filter plate 15, so as to improve the flushing effect.

[0027] like Figure 1 As shown, the inner wall of the fixed leg 11 is fixedly connected to a conveyor belt 3; the end of the conveyor belt 3 is fixedly connected to a lower hopper 31; during operation, when the oil residue after extrusion is cleaned from between the filter plates 15, it will fall to the surface of the conveyor belt 3 below, and then the conveyor belt 3 can be started to transport the fallen oil residue to the lower hopper 31, and then a collecting device can be used to collect the oil residue from under the lower hopper 31 and then transport it away. In this step, the conveyor belt 3 is connected to the lower hopper 31 to facilitate the collection of the oil residue after extrusion, thereby reducing the inconvenience of placing the collecting device from the bottom of the fixed rod 1, so as to improve the convenience during collection.

[0028] like Figure 1 and Figure 3 As shown, the end of the conveyor belt 3 is fixedly connected to a second fixed plate 4; the second fixed plate 4 is arranged away from the lower hopper 31; the side wall of the second fixed plate 4 is fixedly connected to a scraper 41; during operation, when the conveyor belt 3 rotates, the scraper 41 will contact the surface of the conveyor belt 3, and the surface of the conveyor belt 3 can be scraped at this time. In this step, by setting the second fixed plate 4 and the scraper 41, the surface of the conveyor belt 3 can be scraped to reduce the situation where the conveyor belt 3 is dirty due to the oil residue remaining on the surface of the conveyor belt 3 when the conveyor belt 3 is conveying oil residue.

[0029] like Figure 1 As shown, the side wall of the fixed leg 11 is fixedly connected with a collecting groove 5; a pull-out box 51 is placed in the collecting groove 5; the pull-out box 51 is slidably matched with the collecting groove 5; during operation, the oil residue remaining on the surface of the conveyor belt 3 is scraped off by the scraper 41, and then falls into the pull-out box 51 below and is collected. When the collection is completed, the pull-out box 51 is pulled out from the collecting groove 5, and the collected oil residue is taken out and then put back into the collecting groove 5. In this step, by setting the collecting groove 5 and the pull-out box 51, the oil residue scraped off the surface of the conveyor belt 3 can be collected, thereby reducing the situation where the oil residue is scattered and causes dirt.

[0030] like Figure 1As shown, the end of the first oil outlet pipe 14 is connected to the second filter box 6; the side wall of the second filter box 6 is connected to the second oil outlet pipe 61; during operation, when the filtered oil is discharged from the first oil outlet pipe 14, it will enter the second filter box 6. At this time, the filter placed in the second filter box 6 can perform secondary filtering on the oil, and then discharge it from the second oil outlet pipe 61 into the container. In this step, by setting the second filter box 6 to connect the first oil outlet pipe 14 and the second oil outlet pipe 61, the discharged oil can be secondary filtered to reduce the residual oil residue in the oil and improve the quality of the oil.

[0031] like Figure 3 As shown, the side wall of the scraper 41 is fixedly connected with a rubber pad 7; during operation, when the scraper 41 scrapes the surface of the conveyor belt 3, the rubber pad 7 will contact the surface of the conveyor belt 3. In this step, by arranging the rubber pad 7 to connect the scraper 41, the wear of the scraper 41 when scraping the surface of the conveyor belt 3 can be reduced, thereby playing a protective role.

[0032] Working principle: When filtering in the tea oil production process, the raw material is introduced into the filter plate 15 from the feed pipe 13, and then the hydraulic cylinder 17 is started to drive the pressure plate 18 to apply pressure to the filter plate 15. Under continuous pressure, the filter plate 15 will move toward the material box 12. At this time, the oil in the raw material will be discharged from the first oil outlet pipe 14, and the remaining oil residue will remain in the filter plate 15. Then the hydraulic cylinder 17 is contracted to drive the filter plate 15 to reset, and then the oil residue remaining in the filter plate 15 is cleaned up. At this time, the external water source is connected to the first fixed Plate 16, start the water pump 115 to pump water from the first filter box 116, and then spray it onto the filter plate 15 through the outlet pipe 111. At the same time, the linear motor 110 can be started to reciprocate and drive the outlet pipe 111 to move, so that the filter plate 15 can be flushed from the top. When the water flows out of the outlet pipe 111, it will pass through the metal bellows 2, and then enter the nozzle 21 to spray onto the filter plate 15. At this time, the nozzle 21 can disperse the water flow to increase the spraying range of the water. At the same time, the bendable design of the metal bellows 2 can change the nozzle. The spraying direction of 21 can be used to wash the area with more residual oil residue in a targeted manner. When the squeezed oil residue is cleaned from between the filter plates 15, it will fall to the surface of the conveyor belt 3 below. At this time, the conveyor belt 3 can be started to transport the fallen oil residue to the lower hopper 31, and then the collection device can be used to collect the oil residue from the bottom of the lower hopper 31 and then transport it away. When the conveyor belt 3 rotates, the scraper 41 will contact the surface of the conveyor belt 3. At this time, the surface of the conveyor belt 3 can be scraped and swept, and the residual oil residue attached to the surface of the conveyor belt 3 is scraped by the scraper 4 After being scraped, the oil will fall into the drawer box 51 below and be collected. After the collection is completed, the drawer box 51 is pulled out from the collection tank 5, and the collected oil residue is taken out and put back into the collection tank 5. When the filtered oil is discharged from the first oil outlet pipe 14, it will enter the second filter box 6. At this time, the filter screen placed in the second filter box 6 can filter the oil for the second time, and then it will be discharged from the second oil outlet pipe 61 into the container. When the scraper 41 scrapes the surface of the conveyor belt 3, the rubber pad 7 will contact the surface of the conveyor belt 3.
