Description

Technical Field

[0001] This utility model mainly relates to the field of kitchen oil purification, specifically to a high-efficiency solid-liquid separation device for kitchen oil purification. Background Technology

[0002] Food waste processing generates a large amount of waste oil. After proper purification, this oil can be used as an important raw material for producing biodiesel, industrial oils, or feed additives, realizing the resource utilization of waste. However, the crude oil initially collected from food waste has an extremely complex composition, containing a large number of solid impurities such as food scraps, bone fragments, fibers, and various suspended solids. The presence of these impurities not only seriously affects the efficiency and product quality of subsequent deep processing (such as esterification reactions), but also leads to a series of production problems such as pipe blockage and equipment wear. Therefore, efficient and thorough solid-liquid separation is a crucial pretreatment step in the oil purification process.

[0003] During the operation of specific embodiments, the inventors discovered the following defects:

[0004] Filtration separation methods, such as basket filters or vibrating screens, primarily rely on filter screens to intercept solid impurities. While this method is effective at removing large particles, it is prone to rapid clogging when dealing with fine suspended solids and colloidal substances, leading to a sharp increase in filtration resistance and a rapid decrease in processing capacity. Cleaning the filter residue also presents challenges, including inconvenience, residual grease, and the potential for secondary pollution during the cleaning process.

[0005] It should be noted that the above content falls within the scope of the inventor's technical knowledge. Due to the vast and complex nature of the technical content in this field, the above content of this application does not necessarily constitute prior art. Utility Model Content

[0013] Furthermore, the outer wall of the synchronous belt is provided with pusher plates, and the number of pusher plates is set to multiple, with the multiple pusher plates distributed at equal intervals on the outer wall of the synchronous belt.

[0014] 3. Beneficial effects:

[0015] Compared with the prior art, the technical solution provided by this utility model has the following advantages:

[0016] This invention involves placing kitchen grease inside a separating shell and pushing it into the separating tank via a feeding structure. An internal feeding screw then propels the grease forward, with the screw pitch arranged sequentially from wide to narrow, allowing the grease to be squeezed in sequence. This separates impurities from the grease, while the feeding screw pushes impurities out through a first outlet on one side, and the grease out through a second outlet at the bottom.

[0027] Example

[0028] See attached document Figure 1-4 A high-efficiency solid-liquid separation device for purifying kitchen oils includes a separation shell 1, a separation tank 5 inside the separation shell 1, bottom plates 4 on both sides of the separation tank 5, positioning holes 2 at both ends of the separation shell 1 and the separation tank 5, a servo motor 8 on one side of the separation shell 1, a feeding screw 9 at the output end of the servo motor 8, a feeding groove 11 on one side of the separation tank 5, a feeding structure 3 inside the positioning hole 2, a first discharge port 6 on one side of the separation tank 5, support frames 13 on both sides of the bottom of the separation shell 1, a feeding port 7 at one end of the separation shell 1, a feeding port 7 on one side of the top of the separation shell 1, and a feeding screw 9 at the bottom of the separation shell 1. The second discharge port 12 is provided. A filter plate 10 is provided at the bottom of the separation tank 5. The filter plate 10 has an installation groove 14. The kitchen grease is put into the separation shell 1 through the feed port 7 and the kitchen grease is in contact with the bottom plate 4. Then, the kitchen grease is fed into the separation tank 5 from the feed trough 11 through the feeding structure 3. The servo motor 8 is started and drives the feeding screw 9 to rotate. The feeding screw 9 squeezes the kitchen grease that has entered the separation tank 5. The pitch of the feeding screw 9 is wide to narrow so that the kitchen grease can be squeezed and discharged through the filter plate 10 into the bottom of the separation shell 1, so that the kitchen grease is separated from the impurities. The impurities are discharged through the feeding screw 9 and the kitchen grease is discharged from the second discharge port 12.

[0029] Furthermore, the feeding structure 3 includes a rotating shaft 301 rotatably connected to the inner wall of the positioning hole 2. A synchronous wheel 302 is provided on the outer wall of the rotating shaft 301. A synchronous belt 303 is provided on the outer wall of the synchronous wheel 302. A pusher plate 304 is provided on the outer wall of the synchronous belt 303. The number of pusher plates 304 is set to multiple, and the multiple pusher plates 304 are evenly distributed on the outer wall of the synchronous belt 303. When the motor is started, the motor drives the rotating shaft 301 to rotate. The rotating shaft 301 drives the synchronous wheel 302 to rotate. The synchronous wheel 302 drives the synchronous belt 303 to move. The synchronous belt 303 drives the pusher plate 304 on the outer wall to slide on the outer wall of the bottom plate 4, so that the pusher plate 304 can push the kitchen grease on the top of the bottom plate 4 into the interior of the separation tank 5.

[0030] Feeding stage: Kitchen grease enters the separation shell 1 from the feed inlet 7 and falls onto the bottom plate 4.

[0031] Feeding stage: The drive motor of the feeding structure 3 starts, driving the rotating shaft 301 to rotate, and the pusher plate 304 moves through the synchronous pulley 302 and the synchronous belt 303. The pusher plate 304 pushes the grease on the bottom plate 4 into the separation tank 5 through the feed trough 11.

[0032] Extrusion and separation stage: Servo motor 8 starts, driving the feeding screw 9 to rotate. As the pitch of the feeding screw 9 narrows, the grease is gradually squeezed inside the separation tank 5. The grease seeps out through the filter plate 10, enters the bottom of the separation shell 1, and is discharged from the second outlet 12. Solid impurities are pushed to one end of the separation tank 5 by the feeding screw 9 and discharged from the first outlet 6.

[0033] The above-described embodiments are merely illustrative of certain implementations of this utility model, and their descriptions are relatively specific and detailed. However, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
