Description

Technical Field

[0001] The utility model belongs to the technical field of waste edible oil recovery, in particular to an odor-proof sealing device for waste edible oil. Background Art

[0002] Waste cooking oils and fats refer to inedible animal and plant fats and various oil-water mixtures, and are a type of food waste. Waste cooking oils and fats often contain harmful substances such as benzopyrene and aflatoxins, which are harmful to human health and may cause diarrhea, abdominal pain, and cancer. For example, in hot summer months and in high-temperature kitchens, when waste cooking oils and fats are left for long periods of time, due to contact with oxygen in the air, the unsaturated fatty acids in them will undergo oxidation reactions, forming peroxides. These peroxides then decompose into lower fatty acids, aldehydes, ketones, and other substances, producing unpleasant odors and smells, causing the oils and fats to become smelly. Inhalation of these substances can also have adverse health effects.

[0003] However, when waste cooking oil is currently collected in kitchens, it is usually poured directly into a recycling bin for temporary storage. When the bin is full, it is further processed. However, the grease recycling bin is usually open and lacks a odor-proof sealing function. The odor and harmful gases of the waste cooking oil can leak out, causing environmental pollution. Therefore, it is urgent to improve the above-mentioned defects of the existing grease recycling bin. The present invention provides a odor-proof sealing device for waste cooking oil that has a good sealing effect and is convenient for pouring grease. Utility Model Content

The barrel cover 7 is sealed on the top opening of the recycling barrel 1 through a sealing gasket 3. An embedding groove 2 is provided on the top outer edge of the recycling barrel 1. The inner bottom surface of the embedding groove 2 is bonded to the annular sealing gasket 3. A plurality of positioning protrusions 4 are provided in a ring shape around the center of the recycling barrel 1 on the inner wall of the embedding groove 2. A plurality of positioning grooves 10 are provided on the circumferential side of the barrel cover 7. The plurality of positioning protrusions 4 and the plurality of positioning grooves 10 are respectively distributed in a ring shape and are arranged in a one-to-one correspondence. When the barrel cover 7 is embedded in the inner side of the embedding groove 2, the barrel cover 7 is clamped with the positioning protrusion 4 through the positioning groove 10. A fixed pipe 8 is vertically embedded in the center of the barrel cover 7 and is connected to the barrel cover. A self-sealing oil inlet assembly 9 is installed on the upper end of the fixed pipe 8. A liquid level observation plate 11 is embedded and fixed on the outer wall in front of the upper end of the recycling barrel 1. The liquid level observation plate 11 is made of transparent organic glass and its thickness is equal to that of the recycling barrel 1.

[0028] On the basis of the above structure, preferably, the sealing gasket 3 is made of elastic rubber.

[0029] In this embodiment, the provision of the sealing gasket 3 facilitates the sealing between the barrel cover 7 and the recycling barrel 1, thereby preventing the odor of the waste edible oil in the recycling barrel 1 from leaking out.

[0030] As a preferred embodiment, on the basis of the above structure, a sliding groove is further opened inside the positioning protrusion 4, and an adjusting screw 5 is rotatably installed on the middle part of the positioning protrusion 4 through a bearing, and a movable block 6 is threadedly sleeved on the outer side of the adjusting screw 5, and the movable block 6 is engaged and slidably located in the sliding groove inside the positioning protrusion 4.

[0031] In this embodiment, the adjusting screw 5 is used to facilitate the control of the telescopic sliding of the movable block 6. By controlling the movable block 6 to extend and engage with the barrel cover 7, the barrel cover 7 is conveniently positioned.

[0032] As a preferred embodiment, on the basis of the above structure, further, the interfaces between the movable block 6 and the positioning groove 10 are both provided with matching inclined surfaces.

[0033] In this embodiment, by utilizing the inclined surfaces provided at the interfaces of the movable block 6 and the positioning groove 10, when the movable block 6 is extended to engage the barrel cover 7, the barrel cover 7 can also be squeezed downward, thereby facilitating efficient sealing between the barrel cover 7 and the recycling barrel 1 using the sealing gasket 3.

[0034] As a preferred embodiment, on the basis of the above structure, the self-sealing oil inlet assembly 9 further includes a movable tube 91, a support spring 92, a bracket 93 and a sealing steel ball 94. The bottom end of the movable tube 91 is slidably sleeved on the outside of the top end of the fixed tube 8. The support spring 92 is fixedly connected between the bottom end of the movable tube 91 and the fixed tube 8. A bracket 93 is provided on the inner side of the middle part of the movable tube 91. The longitudinal section of the bracket 93 is "T"-shaped. The left and right ends of the top of the bracket 93 are welded to the inner wall of the movable tube 91. The bottom end of the bracket 93 is fixedly connected to the sealing steel ball 94.

[0035] In this embodiment, by pressing down the movable tube 91, the bracket 93 drives the sealing steel ball 94 to move downward synchronously, so that the inlet of the fixed tube 8 can be opened and unobstructed, which is convenient for adding waste cooking oil into the recycling barrel 1. Then, the movable tube 91 can be reset by the support spring 92, so that the sealing steel ball 94 can seal the fixed tube 8 again to prevent odor from leaking out.

[0036] On the basis of the above structure, preferably, the inner diameter of the fixed tube 8 is set to increase gradually from the middle to both ends.

[0037] As a preferred embodiment, based on the above structure, further, the movable tube 91 forms an elastic structure on the outside of the fixed tube 8 through the support spring 92, and the sealing steel ball 94 contacts and seals the fixed tube 8.

[0038] The working principle of this utility model is as follows:

[0039] When in use, first place the bucket cover 7 in the embedding groove 2 opened at the top of the recycling bucket 1, and make the multiple positioning grooves 10 opened on the outer edge of the bucket cover 7 respectively engage with the multiple positioning protrusions 4, then manually rotate the multiple adjusting screws 5 in sequence to control the movable block 6 to extend from the slide groove in the positioning protrusion 4. The extended movable block 6 can utilize the inclined surface provided at the interface between it and the positioning groove 10 to engage and position the bucket cover 7 while also squeezing the bucket cover 7 downward, so as to facilitate the use of the sealing gasket 3 to more efficiently seal the bucket cover 7 and the recycling bucket 1, thereby preventing the odor of the waste edible oil in the recycling bucket 1 from leaking out and achieving the purpose of deodorization;

[0040] When it is necessary to pour waste cooking oil into the recycling bin 1, the movable tube 91 can be manually pushed downward, so that it drives the bracket 93 and the sealing steel ball 94 to move vertically downward synchronously. As the sealing steel ball 94 moves downward, the inlet of the fixed tube 8 can be opened and is in a unobstructed state. At this time, the waste cooking oil can be poured into the recycling bin 1. After the addition is completed, the movable tube 91 can be loosened. The movable tube 91 can be automatically raised and reset by the support spring 92, and the sealing steel ball 94 can be used to seal the fixed tube 8 again to prevent odor from leaking out. In addition, the liquid level observation plate 11 made of transparent organic glass is used to facilitate observation of the waste cooking oil storage amount in the recycling bin 1 for timely cleaning.

[0041] The above are only preferred specific embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Any equivalent changes, modifications, substitutions and variations made by technicians in this technical field based on the concept of the present invention through logical analysis, reasoning or limited experiments on the basis of existing technologies should be within the scope of protection determined by the claims.
