Description

Technical Field

[0001] The utility model relates to the technical field of waste oil recovery, in particular to a kitchen oil separator capable of recovering waste oil. Background Art

[0002] Wastewater discharged from the catering industry or home kitchens contains a large amount of grease, which contains a lot of organic components and can be used as fertilizer and other purposes. However, Chinese cooking also produces a lot of oil smoke. In order to keep the kitchen environment clean and the human body healthy, the kitchen will add oil fume exhaust equipment, which generally uses a filter structure to filter the oil fume. Although the filter structure can block a certain amount of oil fume, the oil fume is attached to the filter, which is not conducive to collection and cleaning. Because it is not easy to clean, after working for a long time, the oil on the filter will stick together and become more and more difficult to clean. Over time, the efficiency of the oil fume exhaust equipment is reduced. Many users often replace the entire oil fume exhaust equipment for this reason, resulting in unnecessary waste of resources.

[0031] Combine the following Figure 1-Figure 5 The utility model describes a kitchen grease separator capable of recycling waste oil.

[0032] like Figure 1 As shown, in one embodiment, a kitchen grease separator capable of recycling waste oil includes a housing 100 , an oil receiving ring 200 , a liquid separation plate 300 and a smoke exhaust pipe 400 .

[0033] The shell 100 is installed in the range hood, and includes a centrifugal part 110 and an oil receiving part 120. The centrifugal part 110 has a smoke inlet 112, which is fixed to the air intake port of the range hood. The centrifugal part 110 and the oil receiving part 120 are threadedly installed, which facilitates disassembly and allows waste oil to be directly recovered from the oil receiving part 120; the oil receiving ring 200 is fixed in the oil receiving part 120 and has an oil leakage hole 210; the liquid separation plate 300 is arranged on the oil receiving ring 200 to buffer the impact of the medium airflow on the oil accumulated at the bottom of the oil receiving part 120, so as to prevent the accumulated oil from entering the conveying medium again. As a preferred embodiment, the liquid separation plate 300 has a mounting hole 310 on one side close to the oil receiving ring 200, and the top surface of the mounting hole 310 is connected to the oil receiving ring 20 through an elastic member. 0 connection, the elastic member is a spring 320, which is used to buffer the medium airflow, reduce the abnormal sound generated by vibration inside the range hood, and stabilize the connection between the centrifugal part 110 and the oil receiving part 120; the smoke exhaust pipe 400 is fixed in the centrifugal part 110, including a sealing part 410 and a hollow part 420, one end of the sealing part 410 located in the centrifugal part 110 is threadedly installed with the hollow part 420, and the other end of the sealing part 410 passes through the centrifugal part 110 and has a connecting part 430, and the connecting part 430 is a flange for connecting to the fan in the range hood. As a preferred embodiment, the hollow part 420 has an air hole 422, and the inclination angle of the air hole 422 is α, and the value range of α is 35°≤α<65. Preferably, the value of α is 45°, refer to Figure 2 and Figure 3 .

[0034] Specifically, an impeller 500 is installed in the hollow portion 420 , a first scraper 600 is abutted on the liquid separation plate 300 , and a connecting rod 700 is fixed between the impeller 500 and the first scraper 600 .

[0035] The kitchen oil separator device capable of recycling waste oil of the present embodiment has a high-speed rotation of the internal fan when the range hood is powered on, and a negative pressure zone is formed in the centrifugal part 110 through the sealing part 410. The negative pressure effect attracts the oil smoke gas to enter the centrifugal part 110 through the smoke inlet 112. The fast smoke hits the liquid separation plate 300 to intercept the large particles of oil and stay on the liquid separation plate 300, and finally gathers in the groove on the oil receiving ring 200. The small particles of oil enter the hollow part 420 with the air flow, and pass through the air holes 422 arranged at an inclined angle. A vortex is formed, which causes the oil-gas mixture to be centrifugally separated, and eventually small particles of oil adhere to the surface of the hollow part 420 and fall again on the separator plate 300 due to gravity, thereby realizing waste oil recovery; the gas after secondary separation is discharged from the fan, reducing the burden of oil particles on the fan; and when the negative pressure passes through the sealing part 410, it drives the impeller 500 to rotate and transmits the rotating force to the first scraper 600 through the connecting rod 700, scraping the oil adhered to the separator plate 300 into the groove on the oil receiving ring 200 for unified recovery.

[0036] Since the fast flue gas enters the centrifugal part 110 and also hits the wall surface of the centrifugal part 110, the oil particles will adhere to the wall surface after cooling, and it is difficult to clean after a long time. Therefore, a second scraper 800 is fixed to the end of the first scraper 600 away from the connecting rod 700, and the second scraper 800 is in contact with the inner wall of the centrifugal part 110. In this way, the first scraper 600 drives the second scraper 800 to rotate at the same time during movement, and scrapes off the oil that still contains heat and adheres to the wall surface. Under the action of gravity, the oil falls into the groove on the oil collecting ring 200 along the second scraper 800 for unified recovery, thereby reducing the dirt on the wall surface.

[0037] The waste oil collected in the groove of the oil receiving ring 200 condenses after a period of time, resulting in poor fluidity. Figure 4 and Figure 5 A push block 220 is slidably installed in the oil receiving ring 200. Preferably, there is an inclination angle β between the push block 220 and the bottom surface of the groove of the oil receiving ring 200, and the value of β is 45°. The push block 220 has a notch 222, and a cross bar 224 is fixedly installed in the notch 222. The cross bar 224 is rotatably connected to the second scraper 800. An elastic member is sleeved on the cross bar 224, and the elastic member is a torsion spring 226. The two ends of the elastic member are respectively fixed to the side wall of the notch 222 and the second scraper 800. The hole walls on both sides of the oil leakage hole 210 have a height difference.

[0038] When the second scraper 800 rotates, the push block 220 is forced to rotate with the oil receiving ring 200, and the torsion spring 226 firmly presses the push block 220 against the bottom surface of the groove of the oil receiving ring 200 through its own pre-tightening force. Therefore, the push block 220 can push the oil into the oil leakage hole 210 during rotation, and then contact the hole wall on the higher side of the oil leakage hole 210. The hole wall will scrape off the oil adhered to the push block 220, and then the push block 220 continues to move in the oil receiving ring 200, over and over again.

[0039] In order to further increase the separation of oil and gas particles in the oil smoke, spiral blades 900 are welded on the outer wall of the exhaust pipe 400. The spiral blades 900 force the oil smoke gas to perform centrifugal swirling motion to generate centrifugal force. In this process, the oil particles with larger specific gravity move downward along the wall under the combined action of gravity and rotating centrifugal force, ultimately achieving a separation effect and improving the separation efficiency.

[0040] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0041] The above-mentioned embodiments only express several implementation methods of the utility model, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the utility model, and these all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
