Description

Technical Field

[0001] The invention belongs to the technical field of woody oil and grease processing, and in particular relates to a woody oil and grease distillation pretreatment filtering device. Background Art

[0002] Woody oil is an edible oil obtained from the seeds or fruits of woody plants by pressing or extracting. These woody plants are usually perennial and have high oil content and economic utilization value. Woody oil plays an important role in agricultural production because they not only provide edible oil, but also have multiple functions such as improving the ecological environment of farmland, preventing wind and sand, and maintaining water and soil. Woody oil needs to go through multiple processing steps such as cleaning, tempering, steaming, pressing, and distillation during processing. Among them, some pretreatment steps are required before distillation. The woody oil liquid is poured into a filter device to filter and remove the solid impurities mixed therein, thereby improving the extraction efficiency of woody oil and improving the quality of woody oil. At the same time, it protects the distillation equipment, avoids the solid impurities in the woody oil to cause wear to the distillation equipment, and reduces the occurrence of safety accidents.

[0003] When the existing woody oil distillation pretreatment filtration device pre-treats and filters woody oil mixed with solid impurities, the solid impurities in the woody oil are left statically inside the filter frame for filtration. The solid impurities remaining inside the filter frame after filtration accumulate inside the filter frame, which is easy to clog the filter frame, thereby affecting the filtration efficiency of the woody oil. Therefore, improvement is needed. Summary of the Invention

[0009] As a further solution of the present invention: feeding ports are symmetrically provided on both sides of the top of the filter frame, a mounting plate is fixedly installed on the top of the filter frame between the two groups of feeding ports, and a plurality of groups of filter mesh holes are evenly provided on the surface of the bottom of the filter frame.

[0010] As a further solution of the present invention: the bottom of the rectangular protective frame is fixedly connected to the top of the mounting pad, a dual-shaft motor is fixedly installed inside the rectangular protective frame, both ends of the dual-shaft motor are fixedly installed with rotating shafts, and the end of the rotating shaft away from the dual-shaft motor is rotatably connected to the inner wall of the rectangular protective frame, and a first transmission wheel is fixedly installed on the surface of the rotating shaft away from the end of the dual-shaft motor.

[0011] As a further solution of the present invention: both ends of the connecting shaft are rotatably connected to the filter frame, and both ends of the connecting shaft pass through the filter frame and are respectively fixedly installed with second transmission wheels, and the positions of the second transmission wheels correspond to the positions of the first transmission wheels. The inner wall of the elastic transmission belt passes around the surfaces of the second transmission wheels and the first transmission wheels, and three groups of concave mounting brackets are fixedly installed at equal angles on the surface of the connecting shaft located inside the filter frame.

DETAILED DESCRIPTION

[0023] The technical solution of the present application will be further described in detail below in conjunction with specific implementation methods.

[0024] like Figure 1-6 As shown, the present invention provides a technical solution: a woody oil and grease distillation pretreatment filtration device, comprising a processing box 1, a curved processing groove 101 is provided on the top of the processing box 1, a discharge trough 102 is provided at the central position of the bottom of the curved processing groove 101, and limiting slide grooves 103 are symmetrically provided on the bottom of both sides of the inner wall of the processing box 1. By providing the limiting slide grooves 103, when the collection box 2 is inserted into the bottom of the processing box 1, the limiting rollers 202 on both sides of the collection box 2 roll inside the limiting slide grooves 103, thereby ensuring that the collection box 2 will not be misaligned or deflected when it is fixed to the bottom of the processing box 1.

[0025] A collection box 2 is slidably installed at the bottom of the processing box 1, and a handle 201 is symmetrically fixedly installed on one side of the collection box 2. Four sets of limiting rollers 202 are fixedly installed on both sides of the collection box 2, and the positions of the limiting rollers 202 correspond to the limiting slides 103. Because the limiting rollers 202 are provided, when the collection box 2 is dragged to move at the bottom of the processing box 1, the limiting rollers 202 are driven to roll inside the limiting slides 103, thereby reducing the friction of the collection box 2 when it moves at the bottom of the processing box 1, making it convenient to pull out the collection box 2 from the bottom of the processing box 1.

[0026] The bottom of the processing box 1 is fixedly installed on one side of the collection box 2, and three groups of mounting grooves 301 are equidistantly provided inside the mounting groove 301. A limiting slide 302 is slidably installed inside the mounting groove 301, and a fixed pressure rod 303 is fixedly installed on the top of the limiting slide 302. The top of the fixed pressure rod 303 passes through the mounting groove 301 and extends to the top of the mounting bar 3. A fixing spring 304 is provided on the surface of the fixing pressure rod 303 located inside the mounting groove 301. The fixing spring 304 presses the limiting slide 302 against the bottom of the mounting groove 301 under the rebound action of the fixing spring 304, so that the limiting slide 302 drives the fixing pressure rod 303 to move downward inside the mounting groove 301 until the fixed clamping plate 305 is pressed against the top of the mounting bar 3;

[0027] Three groups of fixed pressure rods 303 are fixedly installed with fixed clamping plates 305 on the top of the installation slots 301. Because of the fixed clamping plates 305, when the collection box 2 is inserted into the bottom of the processing box 1, one side of the top of the collection box 2 slides through the fixed clamping plates 305, so that the fixed clamping plates 305 can be clamped and fixed to the top of the collection box 2, and the collection box 2 is clamped and fixed to the bottom of the processing box 1, ensuring that the collection box 2 is clamped at the bottom of the processing box 1 and will not slide at will.

[0028] Electric push rods 4 are symmetrically fixedly installed on the surfaces of both sides of the processing box 1. Filter racks 5 are fixedly installed on the tops of the four groups of electric push rods 4. The filter racks 5 are located inside the processing box 1. Because the electric push rods 4 are provided, the four groups of electric push rods 4 are controlled to extend and retract synchronously, thereby controlling the filter racks 5 to move up and down on the top of the arc surface processing tank 101, making it convenient to clean the surface of the filter racks 5.

[0029] Feed openings 501 are symmetrically provided on both sides of the top of the filter frame 5. A mounting pad 502 is fixedly installed on the top of the filter frame 5 between the two groups of feed openings 501. A plurality of groups of filter mesh holes 503 are evenly provided on the surface of the bottom of the filter frame 5. Through the feed openings 501 and the filter mesh holes 503, woody oil grease mixed with solid impurities is poured into the interior of the filter frame 5 from the feed openings 501, so that the woody oil grease passes through the filter mesh holes 503 and falls into the interior of the arc surface processing tank 101. At the same time, the solid impurities in the woody oil grease are filtered and accumulated inside the filter frame 5.

[0030] A rectangular protective frame 6 is fixedly installed at the center of the top of the filter frame 5. Due to the presence of the rectangular protective frame 6, when pouring woody oil grease toward the lower feed port 501, the rectangular protective frame 6 blocks the splashing woody oil grease, preventing the splashing woody oil grease from falling onto the double-output shaft motor 601, the rotating shaft 602, and the first transmission wheel 603 inside the rectangular protective frame 6;

[0031] The bottom of the rectangular protective frame 6 is fixedly connected to the top of the mounting pad 502, and a double-output shaft motor 601 is fixedly installed inside the rectangular protective frame 6. The two ends of the double-output shaft motor 601 are respectively fixedly installed with rotating shafts 602, and the end of the rotating shaft 602 away from the double-output shaft motor 601 is rotatably connected to the inner wall of the rectangular protective frame 6, and the surface of the rotating shaft 602 away from the end of the double-output shaft motor 601 is fixedly installed with a first transmission wheel 603. By providing a double-output shaft motor 601, the double-output shaft motor 601 is started, and the two sets of rotating shafts 602 are controlled to drive the corresponding first transmission wheels 603 to rotate synchronously.

[0032] A connecting shaft 7 is rotatably mounted between the two sides of the inner wall of the filter frame 5. Two sets of elastic transmission belts 8 are respectively installed between the two sides inside the rectangular protective frame 6 and the two ends of the connecting shaft 7 located outside the filter frame 5. The two ends of the connecting shaft 7 are rotatably connected to the filter frame 5. The two ends of the connecting shaft 7 pass through the filter frame 5 and are fixedly mounted with second transmission wheels 701. The positions of the second transmission wheels 701 and the first transmission wheels 603 correspond. The inner wall of the elastic transmission belt 8 passes around the surfaces of the second transmission wheel 701 and the first transmission wheel 603. Due to the presence of the elastic transmission belt 8, the elastic transmission belt 8 is wrapped around the surfaces of the first and second transmission wheels 603 and 701. When the first transmission wheel 603 rotates, the friction between the elastic transmission belt 8 and the surfaces of the first and second transmission wheels 603 and 701 drives the second transmission wheel 701 to rotate, thereby controlling the rotation of the connecting shaft 7 inside the filter frame 5, causing the connecting shaft 7 to stir the woody oil oil inside the filter frame 5 and prevent solid impurities in the woody oil oil from accumulating inside the filter frame 5 and clogging the filter mesh 503.

[0033] Three groups of concave mounting brackets 702 are fixedly installed at equal angles on the surface of the connecting shaft 7 located inside the filter frame 5. Three groups of movable clamping rods 703 are slidably installed on the surface of one side of the concave mounting bracket 702, and the movable clamping rods 703 pass through the concave mounting bracket 702. One end of the three groups of movable clamping rods 703 located inside the concave mounting bracket 702 is fixedly installed with a connecting plate 704. The end of the three groups of movable clamping rods 703 away from the connecting plate 704 passes through the concave mounting bracket 702 and is fixedly installed with a rectangular clamping plate 705. An elastic clamping scraper 706 is fixedly installed on one side of the rectangular clamping plate 705. A clamping spring 707 is provided on the surface of the movable clamping rod 703 located between the concave mounting bracket 702 and the rectangular clamping plate 705. By providing the clamping spring 707 and the elastic clamping scraper 706, the clamping spring 707 and the elastic clamping scraper 706 can be pressed. Under the rebound action of the spring 707, the rectangular pressing plate 705 is pushed toward the inner wall of the filter frame 5, so that the elastic pressing scraper 706 is pressed against the inner wall of the filter frame 5. When the connecting shaft 7 rotates inside the filter frame 5, it drives the three groups of elastic pressing scrapers 706 to rotate on the inner wall of the filter frame 5, so that the elastic pressing scraper 706 pushes the solid impurities that block the filter mesh holes 503 on the inner wall of the filter frame 5, avoiding clogging of the filter mesh holes 503 on the surface of the filter frame 5. At the same time, the concave mounting frame 702 and the elastic pressing scraper 706 can stir the woody oil grease inside the filter frame 5, avoiding the woody oil grease from being left stationary for a long time and causing oxidation reaction, which affects the quality of the woody oil grease.

[0034] The working principle of the present invention is:

[0035] Holding the two sets of handles 201, insert the collection box 2 between the two sets of limiting slide grooves 103 at the bottom of the processing box 1, and ensure that the limiting rollers 202 are stuck in the corresponding limiting slide grooves 103 and roll until the collection box 2 is tightly attached to one side of the mounting bar 3, so that one side of the top of the collection box 2 slides through the hook of the fixed clamping plate 305. Under the rebound action of the fixing spring 304, the fixed clamping plate 305 is pressed and fixed to the top of the mounting bar 3, ensuring that the hook of the fixed clamping plate 305 is stuck on the top of the collection box 2, thereby clamping and fixing the collection box 2 to the bottom of the processing box 1, so that the position of the collection box 2 corresponds to the discharge chute 102;

[0036] The four groups of electric push rods 4 are controlled to retract, driving the filter rack 5 to move downward on the top of the processing box 1 until the filter rack 5 is immersed in the arc surface processing tank 101, and an appropriate amount of woody oil grease mixed with solid impurities is poured into the discharge port 501 on the top of the filter rack 5. At the same time, the double-output shaft motor 601 is started to drive the two groups of first transmission wheels 603 to rotate, and the two groups of second transmission wheels 701 are rotated synchronously through the transmission of the elastic transmission belt 8, so that the connecting shaft 7 drives the three groups of concave mounting frames 702 to rotate synchronously inside the filter rack 5. At the same time, when the concave mounting frames 702 rotate to make the elastic pressing scraper 706 close to the inner wall of the filter rack 5, the squeezing spring 707 is deformed between the concave mounting frame 702 and the rectangular pressing plate 705. Under the rebound action of the pressing spring 707, the elastic pressing scraper 706 is close to the inner wall of the filter rack 5, pushing the solid impurities inside the filter rack 5 to move, and preventing the solid impurities from clogging the filter mesh 503;

[0037] The woody oil grease that passes through the filter mesh 503 falls into the arc surface processing tank 101, slides to the lower material tank 102 inside the arc surface processing tank 101, and gradually falls into the collection box 2 from the lower material tank 102. After a certain amount of woody oil grease accumulates inside the collection box 2, push the fixed card 305 away from the mounting bar 3, pull the handle 201 to pull the collection box 2 out of the processing box 1, and pour the filtered woody oil grease inside the collection box 2 into the distillation device for distillation treatment.
