Description

Technical Field

[0001] This utility model relates to the field of waste treatment technology, and in particular to the oil outlet structure of an oil-water separation component. Background Technology

[0002] Household waste, especially kitchen waste, contains a large amount of oil and water mixture. When undergoing resource recovery treatment such as anaerobic or aerobic fermentation, pre-dehydration and oil removal are necessary. Currently, the commonly used method is to use a press to squeeze out the liquid from the waste. However, this generates a large amount of oily wastewater during waste recovery, causing secondary pollution. Oil-water separation technology can separate the oil and water in the mixture, ensuring that the wastewater meets discharge standards and allowing for the collection and reuse of the separated oil.

[0003] Currently, the oil outlet structure of food waste oil-water separation systems is relatively simple, and it usually has the following defects:

[0004] 1. Food residue blockage: During the oil-water separation process of kitchen waste, some fine food residues and solid impurities may flow towards the oil outlet along with the grease. Although the previous separation stages try to remove solids, it is still difficult to avoid a very small amount entering the oil outlet pipe and gradually accumulating near the outlet. Over time, this can easily cause blockage, affecting the normal discharge of grease, reducing separation efficiency, and even preventing the grease in the entire system from flowing out smoothly, requiring frequent manual cleaning and unblocking.

[0005] 2. Grease Condensation and Blockage: If the ambient temperature is low, especially in equipment without proper insulation, the grease separated from kitchen waste may condense at the oil outlet due to the temperature drop, forming solid or semi-solid grease clumps that directly block the outlet and prevent further grease flow. Additional steps, such as heating the outlet, are required to restore its flow. A common heating method involves installing a heating rod inside the oil-water separator to heat the oil and water, preventing grease condensation. The disadvantages are slow heating, a tendency for the heating rod to dry-burn after the water level drops, and the potential for food residue to scorch onto the heating rod's surface, reducing heating efficiency.

[0006] Therefore, an oil outlet structure for the oil-water separation component is proposed. Utility Model Content

[0007] The purpose of this invention is to provide an oil outlet structure for an oil-water separation component to solve the problems mentioned in the background art.

[0008] To achieve the above objectives, the main technical solutions adopted by this utility model include:

[0009] The oil outlet structure of the oil-water separator includes:

[0010] An oil outlet assembly is provided at the oil outlet of the oil-water separator. The end of the oil outlet assembly away from the oil-water separator is provided with a plug for sealing. The oil-water separator is provided with a drive assembly for driving the plug to flip open and close. The drive assembly is located above the oil outlet assembly.

[0012] As a preferred technical solution, the oil outlet assembly includes a straight pipe communicating with the oil outlet hole of the oil-water separator, a bend pipe communicating with the end of the straight pipe away from the oil-water separator, a plug sealing cap being provided at the end of the bend pipe away from the straight pipe, and a support block being fixedly connected to the bend pipe.

[0013] As a preferred technical solution, the connecting plate is integrally formed with a first lug and a second lug, the first lug being rotatably connected to the output end of the electric push rod, and the second lug being rotatably connected to the support block.

[0014] As a preferred technical solution, the heating assembly includes an oil tank installed on the side of the baffle inside the oil-water separator away from the oil outlet. The oil tank contains heat-conducting oil. A heating rod and a temperature control probe are sealed through one side of the oil tank. The surface of the oil-water separator is provided with through holes for the heating rod and the temperature control probe to pass through. An oil filling port is provided on the top of the oil tank, and a tank cover is threaded into the oil filling port.

[0015] As a preferred technical solution, the heating assembly further includes a protective component and a connecting component. The connecting component is disposed on the surface of the oil-water separator, and the protective component is detachably connected to the oil-water separator via the connecting component.

[0019] This utility model has at least the following beneficial effects:

[0020] This application utilizes the coordinated use of an oil outlet component, a plug, and a drive component. When the oil layer thickness and oil-water level in the oil-water separator reach the conditions for oil extraction, the drive component causes the plug to flip open, allowing the grease to flow quickly from the oil-water separator into the oil collection tank. This prevents food residue accumulation, eliminates the need for frequent manual cleaning and unblocking, and reduces maintenance costs. By employing a separate heating component, the heating component can maintain efficient heating during oil extraction and cleaning within the oil-water separator. This ensures that the grease does not solidify, improves the smoothness of the oil outlet component, and prevents the heating rod from burning dry, thus extending its service life and reducing equipment maintenance costs due to heating rod damage.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figures 1-5 The present invention provides an oil outlet structure for an oil-water separation component, including an oil outlet component 100 disposed at the oil outlet of an oil-water separation tank 1, a plug 200 for sealing, a drive component 300 for driving the plug 200 to flip open and close, and a heating component 400 for preventing grease from solidifying and clogging the oil outlet component 100. The plug 200 is disposed at the end of the oil outlet component 100 away from the oil-water separation tank 1. The drive component 300 and the heating component 400 are respectively disposed on the oil-water separation tank 1, with the drive component 300 located above the oil outlet component 100. The drive component 300 includes an electric push rod 310 rotatably connected to the surface of the oil-water separation tank 1 via a rotating shaft. A support block 320 is fixedly connected to the oil outlet component 100. A connecting plate 330 is movably disposed between the output end of the electric push rod 310 and the support block 320. The connecting plate 330 is fixedly connected to the plug 200.

[0029] The oil outlet assembly 100 includes a straight pipe 110 connected to the oil outlet of the oil-water separator 1. The end of the straight pipe 110 away from the oil-water separator 1 is connected to a bend pipe 120. A plug 200 is sealed at the end of the bend pipe 120 away from the straight pipe 110. A support block 320 is fixedly connected to the bend pipe 120. The oil outlet assembly 100 can export the separated grease from the oil-water separator 1 for convenient unified recycling and processing.

[0030] The connecting plate 330 has a first lug 331 and a second lug 332 integrally formed on it. The first lug 331 is rotatably connected to the output end of the electric push rod 310 through a rotating shaft, and the second lug 332 is rotatably connected to the support block 320 through a rotating shaft. The connecting plate 330 enables the movable connection between the plug 200 and the electric push rod 310. When the electric push rod 310 is started, it can drive the plug 200 to rotate and open and close around the rotating shaft between the second lug 332 and the support block 320.

[0031] The heating assembly 400 includes an oil tank 410 installed on the side of the inner baffle of the oil-water separator 1 away from the oil outlet. The oil tank 410 is filled with heat transfer oil, and the amount of heat transfer oil added is 90% of the volume of the oil tank 410. A heating rod 420 and a temperature control probe 430 arranged vertically and horizontally are sealed through one side of the oil tank 410. The surface of the oil-water separator 1 is provided with through holes for the heating rod 420 and the temperature control probe 430 to pass through. The top of the oil tank 410 is provided with an oil filling port 411, and a tank cover 412 is threaded into the oil filling port 411. The heating assembly 400 can heat the oil and water in the oil-water separator 1. At the same time, the oil tank 410 separates the heating rod 420 from the oil and water, preventing food residue from burning onto the heating rod 420, which helps to ensure the heating effect of the heating rod 420.

[0032] The heating assembly 400 also includes a protective component 440 and a connector 450. The connector 450 is disposed on the surface of the oil-water separator 1. The protective component 440 is detachably connected to the oil-water separator 1 through the connector 450. The protective component 440 is used to shield and protect the wiring terminals of the heating rod 420. Through the cooperation of the protective component 440 and the connector 450, the wiring terminals of the heating rod 420 can be shielded, which helps to improve the safety of the heating rod 420.

[0033] The protective component 440 includes a cover 441, which has openings at the top, bottom, and the side facing the oil-water separator 1. The wiring terminal of the heating rod 420 is located in the inner cavity of the cover 441. Two symmetrical inserts 442 are integrally formed on the cover 441. A connector 450 is provided between each insert 442 and the oil-water separator 1. The cover 441 can shield the side of the heating rod 420 away from the oil-water separator 1 and the left and right sides, while ensuring that the heating rod 420 wires can pass through for wiring operations.

[0034] The top of the cover 441 and the insert 442 are fixedly connected to a baffle 443. The baffle 443 can both shield the top of the heating rod 420 terminal and cooperate with the connector 450 to limit the position of the cover 441 on the oil-water separator 1, so as to prevent the protective component 440 from falling down due to its own weight.

[0035] The connector 450 includes a first straight bar 451 fixedly connected to the surface of the oil-water separator 1. An inclined bar 452 is integrally formed on the side of the first straight bar 451 away from the heating rod 420. A second straight bar 453 is integrally formed on the side of the inclined bar 452 away from the first straight bar 451. A slot is formed between the second straight bar 453 and the oil-water separator 1. An insert bar 442 is inserted into the slot from top to bottom. The connector 450 enables a detachable connection between the protective component 440 and the oil-water separator 1, facilitating subsequent wiring, maintenance, or repair of the heating rod 420.

[0036] The working principle of this utility model is as follows: When the conditions for oil extraction are not met, the output end of the electric push rod 310 pushes forward, driving the connecting plate 330 to move through the rotating shaft. This causes the connecting plate 330 to cause the plug 200 to flip and close around the rotating shaft on the support block 320, ensuring that the sealing ring on the plug 200 is tightly attached to the oil outlet of the bend pipe 120, thus maintaining a sealed state. When the oil layer thickness and oil-water level in the oil-water separator 1 reach the conditions for oil extraction, the output end of the electric push rod 310 retracts backward, driving the connecting plate 330 to move through the rotating shaft. This causes the connecting plate 330 to cause the plug 200 to flip and open around the rotating shaft on the support block 320, allowing the oil in the oil-water separator 1 to flow out quickly through the straight pipe 110 and the bend pipe 120 in sequence.

[0037] The heating rod 420 is activated to heat the heat transfer oil in the oil tank 410, raising the temperature of the oil. The heat is then transferred from the oil tank 410 to the oil-water separator 1, which heats the oil and water, preventing the grease from solidifying and thus avoiding obstruction of the continuous flow of grease. This ensures the smooth flow of grease within the oil outlet assembly 100.

[0038] All parts not described in this utility model are the same as or can be implemented using existing technology. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of this utility model, the scope of which is defined by the appended claims and their equivalents.
