Description

Technical Field

[0001] This utility model belongs to the field of acidified waste oil technology, specifically relating to an acidified waste oil pretreatment device. Background Technology

[0002] Acidified waste oil refers to waste oil that has undergone rancidity and deterioration. Acidified waste oil is mainly composed of free fatty acids, glycerol, and other impurities produced by the decomposition of triglycerides under certain conditions. Due to the diverse sources of acidified waste oil, its internal composition is quite complex, thus requiring pretreatment before processing.

[0003] Most existing pretreatment equipment for acidified waste oil involves adding specific agents and stirring to separate excess components from the acidified waste oil. During this process, because the acidified waste oil contains harmful substances, certain harmful gases such as sulfur dioxide, nitrogen oxides, and carbon monoxide are released, resulting in a poor treatment environment. However, existing pretreatment equipment does not have a gas guiding function, allowing these gases to directly enter the air or escape through pipes, making collection impossible. Furthermore, during use, the existing acidified waste oil treatment equipment remains heavily grease-rich internally. Without timely cleaning, a significant amount of grease accumulates inside the equipment. Chemical cleaning of this grease would pollute the environment, so manual scraping is generally required, which is time-consuming. Utility Model Content

[0004] The technical problem this invention aims to solve is that existing acidified waste oil pretreatment equipment does not have the function of guiding gas, cannot collect it, and has a lot of oil residue inside the treatment equipment, which is time-consuming to remove manually.

[0005] To solve the above-mentioned technical problems, the present invention provides a pretreatment device for acidified waste oil, including a treatment tank. The top of the treatment tank is provided with a cover, and the top of the cover is provided with a feed pipe and an exhaust pipe. A discharge port is provided on one side of the bottom of the treatment tank. A raised placement platform is provided in the middle of the bottom of the treatment tank. A drive shaft is rotatably connected to the placement platform, and a drive mechanism is connected to the bottom of the drive shaft. Multiple stirring rods are located inside the treatment tank along the drive shaft. A drive box is connected above the placement platform along the drive shaft. A first bevel gear, a second bevel gear, and a third bevel gear are rotatably connected inside the drive box. The first and second bevel gears are arranged opposite each other, and the first bevel gear is fixedly connected to the drive shaft. The second bevel gear is rotatably connected to the drive shaft, and the third bevel gear meshes with the first and second bevel gears. A drive disc is located through the top of the drive box, and a rotating frame is fastened to the outside of the drive disc. An oil scraper is connected to the outside of the rotating frame, and a guide ring is rotatably connected above the oil scraper.

[0006] Furthermore, the outer side of the cover is sealed and fastened to the processing tank by multiple latches.

[0007] Furthermore, a corresponding rotating seat is provided at the bottom of the cover, located at the drive shaft.

[0008] Furthermore, the drive mechanism includes a 90-degree angle converter and a motor connected in sequence.

[0009] Furthermore, the plurality of stirring rods are located on the side of the drive shaft near the drive housing.

[0010] Furthermore, the drive box is a sealed structure as a whole, and the rotating frame is rotatably connected to the outer side of the drive direction.

[0011] Furthermore, the bottom of the oil scraper matches the shape of the bottom of the treatment tank, and one side of the oil scraper abuts against the side wall of the treatment tank through a scraper. The top side of the oil scraper is rotatably connected to the drive shaft through a connecting rod, and multiple reinforcing ribs are provided between the oil scraper and the rotating frame.

[0012] Furthermore, the outer diameter of the guide ring is the same as the inner diameter of the processing tank, and the upper end face of the guide ring abuts against the lower end face of the cover.

[0013] The advantages of this utility model compared with the prior art are as follows:

[0014] 1. This acidified waste oil pretreatment equipment can collect the gas generated during the treatment process by setting a separate exhaust pipe above the cover, and increase the collection efficiency by adding external equipment such as exhaust fans;

[0015] 2. This acidified waste oil pretreatment equipment uses an oil scraper that rotates synchronously with the stirring rod to scrape off the residual oil on the inner wall of the treatment tank. At the same time, by setting up a drive box, the drive shaft can drive the oil scraper at different speeds while driving the stirring rod, which can effectively prevent the oil scraper from rotating too fast.

[0024] Example 1:

[0025] As per the instruction manual Figure 1-3 As shown, an acidified waste oil pretreatment device includes a treatment tank 1. The top of the treatment tank 1 is provided with a cover 2. The outer side of the cover 2 is sealed and fastened to the treatment tank 1 by multiple latches 17. The top of the cover 2 is provided with a feed pipe 3 and an exhaust pipe 4. The bottom side of the treatment tank 1 is provided with a discharge port 5. The bottom center of the treatment tank 1 is provided with an inwardly protruding placement platform 6. The placement platform 6 is rotatably connected to a drive shaft 7. The bottom of the cover 2 is provided with a corresponding rotating seat 18 located at the drive shaft 7. The bottom of the drive shaft 7 is connected to a drive mechanism. The drive mechanism includes a 90-degree angle converter 19 and a motor 20 connected in sequence. The drive shaft 7 is provided with multiple stirring rods 8 inside the treatment tank 1.

[0026] In this utility model, the drive shaft 7 is located above the placement platform 6 and connected to the drive box 9. Multiple stirring rods 8 are located on the side of the drive shaft 7 close to the drive box 9. The drive box 9 is rotatably connected to a first bevel gear 10, a second bevel gear 11 and a third bevel gear 12. The second bevel gear 11 passes through the top of the drive box 9 and is provided with a drive disk 13. The drive disk 13 is fastened to the outside of a rotating frame 14, and the rotating frame 14 is rotatably connected to the outside of the drive direction.

[0027] In this utility model, an oil scraper 15 is connected to the outside of the rotating frame 14. The bottom of the oil scraper 15 matches the shape of the bottom of the treatment tank 1, and one side of the oil scraper 15 abuts against the side wall of the treatment tank 1 through the scraper 21. The top side of the oil scraper 15 is rotatably connected to the transmission shaft 7 through the connecting rod 22. At the same time, multiple reinforcing ribs 23 are provided between the oil scraper 15 and the rotating frame 14. A guide ring 16 is rotatably connected to the top of the oil scraper 15. The outer diameter of the guide ring 16 is the same as the inner diameter of the treatment tank 1, and the upper end face of the guide ring 16 abuts against the lower end face of the cover 2.

[0028] As per the instruction manual Figure 4As shown, the drive box 9 is a sealed structure. Inside the drive box 9, a first bevel gear 10, a second bevel gear 11, and a third bevel gear 12 are rotatably connected. The first bevel gear 10 and the second bevel gear 11 are arranged opposite to each other. The first bevel gear 10 is fixedly connected to the drive shaft 7, the second bevel gear 11 is rotatably connected to the drive shaft 7, and the third bevel gear 12 meshes with the first bevel gear 10 and the second bevel gear 11. The second bevel gear 11 passes through the top of the drive box 9 and is provided with a drive disc 13.

[0029] In a specific implementation of this utility model, acidified waste oil enters the treatment tank 1 through the feed pipe 3. After undergoing a stirring pretreatment process in the treatment tank 1, it is discharged from the discharge port 5 for subsequent treatment or recycling. The gas generated during the treatment process is discharged through the exhaust pipe 4, and the collection efficiency is increased by adding external equipment such as exhaust fans.

[0030] The motor 20 drives the transmission shaft 7 to rotate via the 90-degree angle converter 19. Multiple stirring rods 8 connected to the transmission shaft 7 rotate with the rotation of the transmission shaft 7, and pre-treat and mix the acidified waste oil in the treatment tank 1.

[0031] When the drive shaft 7 rotates, it drives the first bevel gear 10, which is fixedly connected to it, to rotate. Since the first bevel gear 10 meshes with the third bevel gear 12, it drives the third bevel gear 12 to rotate. The third bevel gear 12 then meshes with the second bevel gear 11, causing the second bevel gear 11 to rotate. Since the second bevel gear 11 is rotatably connected to the drive shaft 7, the second bevel gear 11 rotates around the drive shaft 7 under its drive. In turn, the second bevel gear 11 drives the outer locking rotating frame 14 to rotate, causing the outer connected oil scraper 15 to rotate inside the treatment tank 1 under the drive of the rotating frame 14. When the oil scraper 15 rotates, its stability is maintained by the upper guide ring 16 to prevent the oil scraper 15 from shaking or shifting during rotation. The oil scraper 15 scrapes the waste oil off the inner wall of the treatment tank 1, preventing the waste oil from accumulating on the tank wall and bottom, which would affect the normal operation of the equipment and the treatment effect.

[0032] The present invention and its embodiments have been described above. This description is not restrictive, and the specific embodiments shown are only one of the embodiments of the present invention. The actual structure is not limited to this. In short, if a person skilled in the art is inspired by this description and designs a similar structure and embodiment without departing from the inventive spirit of the present invention, such design should fall within the protection scope of the present invention.
