Description

Technical Field

[0001] This utility model relates to the field of oil sludge cleaning technology for oil presses, specifically to an oil sludge cleaning device for oil presses. Background Technology

[0002] Screw oil presses are mainly used for individual oil extraction. This product belongs to the category of hydraulic fully automatic oil presses. When the oil press is running, the processed oilseeds enter the pressing cylinder from the hopper. The rotating pressing screw continuously pushes the material inward for pressing. Because the material is in motion within the pressing cylinder, under the high pressure of the cylinder, significant frictional resistance is generated between the material, the pressing screw, and the pressing chamber. This friction causes relative movement between the material and the screw. On the other hand, because the diameter of the mounting shaft gradually increases and the pitch gradually decreases, when the pressing screw rotates, the material can both move forward and tumble outward. Simultaneously, the gradually decreasing pressing space improves the pressing effect.

[0003] Oil presses require the separation of oil residue during the pressing process. However, the oil extracted by existing oil presses still contains a lot of impurities and needs to be filtered again, which is inconvenient. In addition, the machine is prone to clogging during the filtration process, requiring manual unclogging and resulting in low oil extraction efficiency. To address these issues, we have proposed an oil press sludge cleaning device. Utility Model Content

[0026] This device, through the setting of cleaning component 7, solves the problem that existing oil presses still contain a lot of impurities, and that the machine is prone to blockage during the filtration process, requiring manual unblocking and resulting in low oil extraction efficiency.

[0027] Furthermore, a rinsing assembly 8 is provided on the top of the processing box 1. The rinsing assembly 8 includes a water tank 81, a second movable rod 82, a bevel gear 83, a connecting plate 84, and nozzles 85. The water tank 81 is fixedly installed on the top of the processing box 1. A water pump is installed inside the water tank 81 to facilitate control of the water pressure sprayed by the nozzles 85. The lower end of the water tank 81 is rotatably connected to the second movable rod 82. The bottom of the second movable rod 82 is fixedly connected to the bevel gear 83, which meshes with the bevel gear 71.

The six sets of nozzles 85 are connected to the inside of the water tank 81 through connecting pipes. Figure 3As shown, this structure is used to mesh with bevel gear 71 and bevel gear 83. When bevel gear 71 rotates, it drives bevel gear 83 to rotate, causing the nozzle 85 at the connecting plate 84 to rotate. The nozzle 85 sprays high-temperature water to soften stubborn oil stains, making it easier to clean the inside of the processing box 1.

[0028] Furthermore, the upper end of the fixed pipe 72 is connected to the opening of the slag discharge port 3, the outer periphery of the screen 73 is fixedly connected to the inner wall of the fixed pipe 72, the bottom of the first movable rod 74 is rotatably connected to the center position of the fixed pipe 72, the other end of the first movable rod 74 is fixedly connected to a second bevel gear 75, the rear end of the first bevel gear 71 is fixedly connected to an mounting shaft 5, the second bevel gear 75 and the first bevel gear 71 mesh with each other, the inner wall of the guide plate 76 is fixedly connected to the outer surface of the first movable rod 74, and the bottom of the guide plate 76 is fixedly connected to a scraper 77. Figure 4 As shown, this structure is used to drive the mounting shaft 5 and the bevel gear 71 to rotate via the servo motor 4. Under the action of the bevel gear 71 and the bevel gear 75 meshing with each other, the bevel gear 75 and the first movable rod 74 rotate, guiding and clearing the internal impurities to facilitate the discharge of sludge. At the same time, the scraper 77 at the bottom rotates 360 degrees on the surface of the screen 73, adhering to the bore wall to scrape off the sludge and prevent blockage.

[0029] Furthermore, the inner wall of the processing box 1 is provided with a stabilizing component 9, which includes a fixing rod 91, a fixing block 92, and a bevel gear 93.

The fixing block 92 has a movable groove, and the bevel gear 93 is rotatably connected inside the fixing block 92. The bevel gear 93 meshes with bevel gear 75 and bevel gear 83. Figure 3 As shown, this structure is used to enclose bevel gear 1 71, bevel gear 2 75 and bevel gear 3 83 through the fixing block 92 at the fixing rod 91 and bevel gear 4 93, to prevent impurities from entering and affecting rotation. At the same time, bevel gear 4 93 assists in the rotation, so that bevel gear 2 75 and bevel gear 3 83 can rotate stably.

[0030] Furthermore, an oil pan 10 is fixedly installed on the left side of the processing box 1, and an oil tank 11 is placed below the oil pan 10.

The output end of the oil sludge suction pump 14 is connected to the inside of the oil tank 11. A connecting pipe 15 is installed on the top of the oil sludge suction pump 14, and the other end of the connecting pipe 15 is connected to the inside of the feed hopper 2. A slag box 12 is placed at the front of the processing box 1, and a guide plate 13 is fixedly connected to the bottom of the slag discharge port 3. The cross-section of the guide plate 13 is a right-angled triangle. Figure 1and Figure 2 As shown, this structure is used to guide the discharged impurities through the guide plate 13, so that they are poured into the slag box 12 for collection, and then the sludge at the bottom of the oil tank 11 is extracted by the sludge suction pump 14, and the sludge is transported to the feed hopper 2 through the connecting pipe 15 for repeated pressing.

[0031] Furthermore, the fixed block 92 has a spherical cross-section, and the fixed block 92 has holes that are compatible with the first movable rod 74 and the second movable rod 82. For example... Figure 3 As shown, the structure is designed so that the fixed block 92 is spherical, which facilitates the downward flow of impurities and water along the surface of the fixed block 92 when the nozzle 85 cleans the inside of the processing box 1, thus avoiding accumulation.

[0032] Furthermore, the guide plate 76 is spiral-shaped, and the diameter of the scraper 77 is matched with the inner diameter of the fixed tube 72. For example... Figure 4 As shown, this structure is used to guide impurities through the spiral-shaped guide plate 76, which facilitates the clearing of impurities and enables quick cleaning.

[0033] Working principle: When using, such as Figure 1 and Figure 2 As shown, the material is poured into the processing box 1 through the feed hopper 2. The servo motor 4 is started to drive the mounting shaft 5 and the pressing screw 6 to rotate. The material is continuously pushed inward by the pressing screw 6 for pressing. The pressed oil flows out from the oil pan 10 and flows into the oil tank 11. The pressed impurities enter the slag discharge port 3. Figure 3 and Figure 4 As shown, when the mounting shaft 5 rotates, the first bevel gear 71 rotates, assisted by the fourth bevel gear 93, so that the second bevel gear 75 and the third bevel gear 83 rotate stably. When the second bevel gear 75 and the first movable rod 74 rotate, they guide and unclog the internal impurities to facilitate the discharge of sludge. At the same time, the scraper 77 at the bottom rotates 360 degrees on the surface of the screen 73, scraping off the sludge against the bore wall to prevent blockage. When the first bevel gear 71 rotates, it drives the third bevel gear 83 to rotate, causing the nozzle 85 at the connecting plate 84 to rotate. The nozzle 85 sprays high-temperature water to soften stubborn grease, making it easier to clean the inside of the processing box 1. The guide plate 13 guides the discharged impurities to be poured into the slag box 12 for collection. The above is the complete working principle of this utility model.
