Description

Technical Field

[0001] This utility model relates to the field of waste oil recycling technology, specifically to a high-efficiency waste oil recycling device. Background Technology

[0002] Waste oil recycling equipment is an environmentally friendly device specifically designed to collect, process, and reuse various types of waste oils. Its core function is to effectively separate waste oils generated during catering, industrial production, and other processes, such as frying oil, lubricating oil, and cutting fluid, from the mixture through specific technical means, removing impurities, moisture, and harmful substances, so that they meet the standards for reprocessing or safe disposal. This achieves resource recycling and reduces environmental pollution, and is an important tool for promoting green and sustainable development, reducing energy consumption, and protecting the ecological environment.

[0003] Existing waste oil recycling devices primarily focus on core aspects such as waste oil collection, separation, and purification in their functional design. However, they generally lack consideration for effectively scraping and cleaning the inner walls of the device. During long-term use, impurities, residues, and grease in the waste oil gradually adhere to the inner walls of the device, forming a stubborn deposit layer. This not only reduces the effective internal volume of the device, affecting the flow and processing efficiency of waste oil, but may also lead to bacterial growth, odors, and even secondary pollution of the recycled waste oil due to the putrefaction and deterioration of the deposits. Existing devices cannot automatically or conveniently clean this inner wall dirt, causing many inconveniences in actual use and maintenance.

[0004] Therefore, we propose a high-efficiency waste oil recovery device. Utility Model Content

[0005] The purpose of this invention is to provide a high-efficiency waste oil recovery device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a high-efficiency waste oil recovery device, comprising:

[0007] A processing box, wherein a material inlet is provided at the top of the processing box, and a transport cylinder is fixedly connected inside the processing box;

[0008] The processing box is equipped with a filtration mechanism, which includes a guide plate. The guide plate is symmetrically and fixedly connected inside the processing box, and one end of the guide plate is fixedly connected to the transport cylinder. The transport cylinder is located inside the processing box and has filter holes on its outer side.

[0009] A cleaning mechanism is installed inside the processing box. The cleaning mechanism includes a gear ring, which is fixedly connected to the inner wall of the processing box. A drive plate is rotatably installed inside the processing box, and one end of the drive plate is fixedly connected to the inside of the drive gear.

[0010] Preferably, the filtration mechanism further includes a rotating rod, which is rotatably mounted inside the conveying cylinder. A spiral blade is fixedly connected to the outside of the rotating rod, and a discharge port is provided at the bottom of one end of the conveying cylinder. During the conveying process, the liquid portion of the waste oil seeps out through the filter holes on the outside of the conveying cylinder, achieving preliminary filtration. The filtered waste residue is then pushed by the spiral blade and finally discharged from the discharge port at the bottom of one end of the conveying cylinder.

[0011] Preferably, a drive gear is rotatably mounted on the outside of the processing box, and the drive gear is fixedly connected to the rotating rod inside. A driving gear is rotatably mounted on the outside of the processing box, and the outer side of the driving gear is meshed with the drive gear. A rotary motor is mounted on the outside of the processing box, and the output end of the rotary motor is fixedly connected to the driving gear. When the rotary motor is started, its output end drives the driving gear to rotate. Since the driving gear meshes with the drive gear, the drive gear rotates accordingly and drives the rotating rod inside the conveying cylinder to rotate. The spiral blades on the outside of the rotating rod rotate synchronously, conveying the waste oil forward in the conveying cylinder.

[0012] Preferably, a driven gear is rotatably mounted on the outside of the processing box, and the driven gear meshes with the driving gear on its outer side. A stirring rod is rotatably mounted inside the processing box, and one end of the stirring rod passes through the inside of the processing box and is fixedly connected to the driven gear. The driven gear on the outside of the processing box rotates under the drive of the driving gear, which drives the stirring rod to rotate, further stirring the filtered waste oil in the processing box and improving its uniformity.

[0013] Preferably, the cleaning mechanism further includes a rotating gear. A rotating gear is rotatably mounted on the other end of the drive plate, and the outer side of the rotating gear meshes with the inner side of a gear ring. A sliding block is rotatably mounted on the front end of the rotating gear, and a limiting frame is slidably mounted on the outer side of the sliding block. Connecting rods are fixedly connected to both ends of the limiting frame, and a scraper is fixedly connected to the other end of each connecting rod. When the drive gear rotates, it also drives the drive plate to rotate. The rotating gear at the other end of the drive plate meshes with the gear ring fixed to the inner wall of the processing box, and rotates on its own axis while revolving with the drive plate. The sliding block at the front end of the rotating gear slides within the limiting frame, causing the limiting frame to drive the scraper to move via the connecting rod. The scraper makes close contact with the inner wall of the processing box, scraping away and cleaning the oil and impurities adhering to the inner wall, keeping the inner wall clean.

[0014] Preferably, a recycling bin is fixedly connected to the outside of the processing box.

[0015] Preferably, a control panel is installed on the outside of the processing box, and the rotating motor is electrically controlled and connected by the control panel.

[0016] Compared with existing technologies, the beneficial effects of this utility model are as follows: The combination of the guide plate, filter holes, rotating rod, spiral blades, and discharge port enables the discharge of filtered waste residue during the filtration process, and timely clears blockages in the filter holes, keeping them unobstructed. This ensures stable and efficient operation of the filtration process, maintains good filtration results, makes the recovered waste oil purer, improves the quality for subsequent reuse, extends the service life of the filtration device, reduces overall operating costs, and ensures the continuous and smooth operation of waste oil recycling. The combination of the gear ring, drive plate, rotating gear, sliding block, limit frame, connecting rod, and scraper enables scraping of the inner wall surface. Scraping cleans the inner wall, keeping it clean, ensuring smooth waste oil flow, improving the efficiency of filtration and separation processes, extending the device's service life, reducing equipment failures and maintenance costs caused by dirt accumulation, and ensuring efficient, stable, and environmentally friendly waste oil recycling.

A spiral blade 7 is fixedly connected to the outside of the rotating rod 6, and a discharge port 8 is provided at the bottom of one end of the conveying cylinder 3. During the conveying process, the liquid portion of the waste oil seeps out through the filter holes 5 on the outside of the conveying cylinder 3, achieving preliminary filtration. The filtered waste residue is then discharged from the discharge port 8 at the bottom of one end of the conveying cylinder 3 under the push of the spiral blade 7.

[0028] Please see Figure 3 A drive gear 9 is rotatably mounted on the outside of the processing box 1, and the drive gear 9 is fixedly connected to the rotating rod 6 inside.

When the rotary motor 11 is started, its output end drives the drive gear 10 to rotate. Since the drive gear 10 meshes with the drive gear 9, the drive gear 9 rotates accordingly and drives the rotating rod 6 inside the transport cylinder 3 to rotate. The spiral blades 7 on the outside of the rotating rod 6 rotate synchronously, conveying the waste oil forward in the transport cylinder 3.

[0029] Please see Figure 3 A driven gear 12 is rotatably mounted on the outside of the processing box 1, and the driven gear 12 is meshed with the driving gear 10.

[0032] Please see Figure 1 The processing box 1 is equipped with a control panel 22 on its outside, and the rotating motor 11 is electrically controlled and connected to the control panel 22.

[0033] Working principle: First, waste oil enters the device through the inlet 2 at the top of the processing tank 1 and flows into the conveying cylinder 3 under the guidance of the guide plate 4. At this time, the rotating motor 11 is started, and its output end drives the drive gear 10 to rotate. Since the drive gear 10 meshes with the drive gear 9, the drive gear 9 rotates accordingly and drives the rotating rod 6 inside the conveying cylinder 3 to rotate.

During the conveying process, the liquid part of the waste oil seeps out through the filter holes 5 opened on the outside of the conveying cylinder 3, achieving preliminary filtration. The filtered waste residue is finally discharged from the outlet 8 at the bottom of one end of the conveying cylinder 3 under the push of the spiral blades 7. Simultaneously, when the drive gear 10 rotates, it also drives the drive plate 15 to rotate. The rotating gear 16 at the other end of the drive plate 15 meshes with the gear ring 14 fixed to the inner wall of the processing box 1. While rotating with the drive plate 15, it also rotates on its own axis. The sliding block 17 at the front end of the rotating gear 16 slides in the limiting frame 18, causing the limiting frame 18 to drive the scraper 20 to move through the connecting rod 19. The scraper 20 is in close contact with the inner wall of the processing box 1, scraping and cleaning the oil stains and impurities adhering to the inner wall, keeping the inner wall clean. In addition, the driven gear 12 on the outside of the processing box 1 rotates under the drive of the drive gear 10, driving the stirring rod 13 to rotate, further stirring the filtered waste oil in the processing box 1 to improve its uniformity. The treated waste residue enters the recycling box 21 fixedly connected to the outside of the processing box 1 for discharge.
