Description

Technical Field

[0001] This utility model relates to the field of slag scraping technology, specifically a rapeseed oil slag scraping device. Background Technology

[0002] After rapeseed oil flows out of the oil press, the oil contains impurities including oil residue. In order to facilitate the removal of these oil residues, an oil residue scraping device is needed. Some technical solutions have also appeared in the prior art, such as the device described in announcement number: CN220999595U, which includes a frame-shaped frame and a filter screen at the bottom of the frame-shaped frame, and also includes a mud scraping assembly located inside the frame-shaped frame. The mud scraping assembly includes a first mud scraper and a second mud scraper. The first mud scraper is located between the vertical walls on both sides of the longitudinal direction of the frame-shaped frame and can slide along the length of the frame-shaped frame. The bottom of the first mud scraper abuts against the upper surface of the filter screen. Although the above-mentioned device can scrape and squeeze the oil residue, the oil residue is always located on the same filter screen and lacks a matching storage mechanism. Later, it is necessary to stop the machine to clean the oil residue on the filter screen. It is not possible to remove the oil residue in the corresponding position without stopping the machine, which leads to a decrease in the filtration efficiency of the device. Utility Model Content

[0003] The purpose of this invention is to provide a rapeseed oil residue scraping device to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: A rapeseed oil residue scraping device includes a filter box, an oil inlet pipe is fixedly connected to the rear surface of the filter box, and two mounting seats are fixedly connected to the upper surface of the filter box. A stepper motor is fixedly connected to the side surface of the mounting base, and a lead screw is rotatably connected to the inner surface of the mounting base. The output end of the stepper motor is fixedly connected to the lead screw, and a pressing mechanism is threadedly connected to the outer surface of the lead screw.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figure 1-4 In this embodiment of the utility model, a rapeseed oil residue scraping device includes a filter box 1, an oil inlet pipe 102 is fixedly connected to the rear surface of the filter box 1, and two mounting seats 2 are fixedly connected to the upper surface of the filter box 1. A stepper motor 201 is fixedly connected to the side surface of the mounting base 2, and a lead screw 203 is rotatably connected to the inner surface of the mounting base 2. The output end of the stepper motor 201 is fixedly connected to the lead screw 203. A pressing mechanism 3 is threadedly connected to the outer surface of the lead screw 203. The pressing mechanism 3 includes a sliding seat 301, a roller 302 and an electric push rod 304. The sliding seat 301 is threadedly connected to the outer surface of the lead screw 203. The roller 302 is rotatably connected to the lower surface of the sliding seat 301. The electric push rod 304 is fixedly connected to the inside of the sliding seat 301. A pressing frame 307 is fixedly connected to the output end of the electric push rod 304. A storage drawer 5 is slidably connected to the front surface of the filter box 1. A first filter screen 501 is fixedly connected to the lower surface of the storage drawer 5. A second filter screen 504 is placed inside the second placement groove 401.

[0016] Specifically, rapeseed oil enters the filter box 1 through the oil inlet pipe 102 for filtration. The stepper motor 201 is started, and the output end of the stepper motor 201 drives the lead screw 203 to rotate. The shield 202 covers the lead screw 203. The thread on the lead screw 203 is a trapezoidal thread with a self-locking function. Under the push of the thread of the lead screw 203, the sliding seat 301 moves along the slide rail 204. The roller 302 rolls on the slide rail 204 to keep the sliding seat 301 balanced during movement. This causes the extrusion frame 307 and the second filter screen 504 to scrape the oil residue to the position of the first filter screen 501. With the help of the electric push rod 304, the extrusion frame 307 moves downward to squeeze the oil residue, extruding some of the rapeseed oil from the residue and reducing the rapeseed oil content in the residue.

[0017] Example 1 like Figure 1-4 As shown, a support leg 101 is fixedly connected to the lower surface of the filter box 1, an oil outlet pipe is fixedly connected to the lower surface of the filter box 1, a first placement groove 4 is opened inside the filter box 1, a second placement groove 401 is opened inside the filter box 1, a storage drawer 5 is slidably connected to the first placement groove 4, a handle 502 is fixedly connected to the front surface of the storage drawer 5, and a bolt 503 is threadedly connected to the upper surface of the handle 502.

[0018] In this embodiment, the support leg 101 lifts the entire filter box off the ground, making it easy to place an oil receiving container below the oil outlet pipe. The oil outlet pipe is connected to the lowest point of the inner cavity of the filter box 1, which can completely discharge the filtered clean oil and avoid liquid accumulation at the bottom of the box. The first placement groove 4 and the storage drawer 5 form a drawer structure, which is conducive to the quick pushing and pulling of the storage drawer 5. The second placement groove 401 is used to horizontally limit the second filter screen 504 to prevent it from shifting laterally during the sludge scraping process. The handle 502 and the bolt 503 form a locking mechanism. When the bolt 503 is turned, it presses the protruding position on the front surface of the filter box 1, and the storage drawer 5 is locked to prevent it from moving by pushing. Conversely, when the bolt 503 is loosened, the storage drawer 5 can be pulled out through the handle 502 for easy cleaning of oil sludge.

[0019] like Figure 1-4 As shown, a shield 202 is fixedly connected to the inner surface of the mounting base 2, and a slide rail 204 is fixedly connected to the inner surface of the mounting base 2. The roller 302 and the slide rail 204 are tactilely connected.

[0020] In this embodiment, the shield 202 is an inverted U-shaped thin-walled structure, which covers the lead screw 203 to prevent rapeseed oil from dripping or dust from adhering to the surface of the lead screw 203, thereby reducing thread wear and the risk of jamming. The slide rail 204 is fixed to the inside of the mounting base 2 by bolts, forming a double-rail structure parallel to the lead screw 203. Together with the roller 302, it enables the sliding seat 301 to remain stable when subjected to extrusion reaction force, thereby reducing frictional resistance and extending the life of the lead screw 203.

[0021] Example 2 Based on Example 1, in order to overcome the problem of inconvenience in squeezing oil residue in Example 1.

[0022] like Figure 1-4 As shown, an energy storage battery 303 is fixedly connected inside the sliding seat 301, and a controller 306 is fixedly connected to the upper surface of the sliding seat 301. The energy storage battery 303, the controller 306 and the electric push rod 304 are electrically connected. A guide rod 305 is fixedly connected to the inner bottom surface of the extrusion frame 307. The guide rod 305 passes through the sliding seat 301 and is slidably connected to the sliding seat 301.

[0023] In this embodiment, the energy storage battery 303 is a 24V rechargeable lithium battery, installed in the sealed battery compartment of the sliding seat 301, which powers the electric push rod 304 and the controller 306, eliminating the constraints of external power cords and preventing cables from getting tangled during movement. The controller 306 adopts a wireless remote control method, which can remotely set the extension and retraction amount and holding time of the electric push rod 304 to achieve differentiated extrusion of oil residue with different moisture contents. The guide rods 305 are symmetrically arranged on both sides of the electric push rod 304, with the lower end fixed to the extrusion frame 307 and the upper end slidingly engaged with the sliding seat 301 to form a double guide structure. When the electric push rod 304 drives the extrusion frame 307 to rise and fall, the guide rods 305 can counteract the lateral torque on the frame, prevent the extrusion frame 307 from tilting, and ensure the parallelism between the extrusion frame 307 and the second filter screen 504, further realizing the downward extrusion of oil residue, thereby improving the oil residue extrusion efficiency.
