Description

Technical Field

[0001] This utility model relates to the field of waste treatment technology, specifically to an oil-water separation component and a waste interception device. Background Technology

[0002] Every day, we generate a lot of garbage, and some kitchen waste contains oil and water. To facilitate subsequent garbage disposal, it is necessary to separate the oil and water in the kitchen waste beforehand. There are several existing methods for oil-water separation. For example, some methods use a heater to heat the oil and water to separate them into layers.

[0003] Prior art, disclosed in announcement number CN111533356B, is a device for separating oil and water from kitchen organic waste. The device includes a main support frame, a motor support frame fixedly mounted on one end of the upper surface of the main support frame, a drive motor fixedly mounted on the upper surface of the motor support frame, and a first shaft seat fixing frame fixedly mounted on the side of the upper surface of the main support frame near the motor support frame. A first bearing seat is fixedly mounted on the upper surface of the first shaft seat fixing frame. In this invention, the mixing drum, used in conjunction with the conveying paddle, can remove oil and water from the kitchen organic waste, thereby improving the oil and water removal rate. The first electric cylinder, used in conjunction with the movable baffle, facilitates the discharge of kitchen organic waste by the conveying paddle. The oil-water separation mechanism can intercept and remove floating scum particles in the oil and water, and also facilitates oil-water separation, improving the efficiency of oil-water separation.

[0004] However, existing waste oil-water separation devices still have defects. For example, during the waste treatment process, oil and water waste will pass through the dehydration tank, the mixing drum and the interception tank in sequence, and finally the oil and water will be separated in the oil-water separation tank. This results in multiple working parts such as the dehydration tank, the mixing drum and the interception tank being covered with oil, making it troublesome to clean the working parts afterwards. Utility Model Content

[0005] The purpose of this utility model is to overcome the above-mentioned technical deficiencies and propose an oil-water separation component and a waste interception device to solve the technical problem that in the existing waste oil-water separation device, during the waste treatment process, oil and water waste will pass through the dehydration tank, the mixing drum and the interception tank in sequence, and finally the oil and water will be separated in the oil-water separation tank. This results in multiple working parts such as the dehydration tank, the mixing drum and the interception tank being covered with oil, making subsequent cleaning of the working parts troublesome.

[0006] To achieve the above-mentioned technical objectives, the present invention adopts the following technical solution:

[0007] In a first aspect, this utility model provides an oil-water separation component, comprising:

[0008] A container, having an internal cavity and an opening at one end; and

[0009] An oil-water separator is disposed on the cavity wall of the accommodating cavity and close to the opening. A separation groove for intercepting oil flow is formed between the side of the oil-water separator facing away from the opening and the cavity wall of the accommodating cavity.

[0010] In some embodiments, the oil-water separator laterally covers the width of the opening.

[0011] In some embodiments, the oil-water separation assembly further includes an oil-absorbing cloth disposed on the side of the oil-water separator facing away from the opening.

[0012] In some embodiments, the oil-water separator includes a first intercepting plate and a second intercepting plate connected to each other and arranged at an angle. The first intercepting plate is located between the second intercepting plate and the bottom of the accommodating cavity, and the separation groove is formed between the side of the first intercepting plate facing the bottom of the accommodating cavity and the cavity wall of the accommodating cavity.

[0013] In some embodiments, the second cutoff plate extends beyond the opening, which is located between the first cutoff plate and the second cutoff plate.

[0014] In some embodiments, the container has a discharge notch at the edge near the opening, the connection between the second intercepting plate and the first intercepting plate is located below the discharge notch, and the second intercepting plate is angled downward toward the discharge notch.

[0015] Secondly, this utility model also provides a waste interception device, including a fixed bracket, a drive assembly, and the aforementioned oil-water separation assembly. The container is rotatably connected to the fixed bracket on the side near the oil-water separator, and the drive assembly is connected to the container and can drive the container to rotate.

[0016] In some embodiments, the drive assembly includes a drive member, a rotating shaft, and a drive rod. The two ends of the rotating shaft are rotatably connected to the fixed bracket. One end of the drive rod is connected to the rotating shaft, and the other end is movably connected to the container. The drive member is disposed in the container and connected to the rotating shaft.

[0017] In some embodiments, the drive includes a motor and a drive gear connected together, the motor being disposed in the container, and the shaft having a driven gear that meshes with the drive gear and whose rotation axes are perpendicular to each other.

[0018] In some embodiments, the drive assembly further includes a slide rail, and the end of the drive rod away from the pivot has a protrusion, which slides and rotates to engage with the slide rail.

[0019] Compared with existing technologies, the oil-water separation component provided by this utility model has a container with an internal cavity for holding kitchen waste to be processed. After the kitchen waste is left to stand in the container for a period of time, the oil in the kitchen waste can float to the surface. At this time, the container is rotated to pour out the kitchen waste from the container, and the oil floating on the surface can be blocked by the oil-water separator to intercept the oil. It can be seen that, compared with the prior art, the oil-water separation component of this application can separate oil and water during the process of pouring out kitchen waste, with the oil remaining in the container. The kitchen waste poured out of the container has little or no oil, and the subsequent waste processing components will not be covered with a lot of oil, making cleaning convenient.

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0024] To address the technical problem in existing waste oil-water separation devices where oil and water waste sequentially pass through a dehydration tank, a mixing drum, and a interception tank before finally separating in the oil-water separation tank, resulting in oil adhering to multiple working components such as the dehydration tank, mixing drum, and interception tank, and subsequent cleaning is cumbersome, this invention provides an oil-water separation component that enables oil-water separation during the initial dumping of kitchen waste. This ensures that subsequent waste processing components are largely free of oil, making cleaning convenient.

[0025] It should be noted that the oil-water separation component described in this utility model is used in, but not limited to, waste interception devices. For ease of explanation, this utility model only uses the application of the oil-water separation component in a waste interception device as an example. The principle of the oil-water separation component in other types of equipment is essentially the same as that in the waste interception device, and will not be described in detail here.

[0026] Please see Figure 1 and Figure 2 , Figure 1This is a schematic diagram of the structure of an oil-water separation component in one embodiment of the present invention. The oil-water separation component includes a container 1 and an oil-water separator 2. The container 1 has a receiving cavity 11 and an opening 12 at one end. The oil-water separator 2 is disposed on the cavity wall of the receiving cavity 11 and close to the opening 12. A separation groove 21 for intercepting oil flow is formed between the side of the oil-water separator 2 facing away from the opening 12 and the cavity wall of the receiving cavity 11.

[0027] In this embodiment, the container 1 has a receiving cavity 11 for holding kitchen waste to be processed. After the kitchen waste has been left to stand in the receiving cavity 11 for a period of time, the oil in the kitchen waste will float to the surface. The opening 12 allows the kitchen waste in the receiving cavity 11 to be poured out when the container 1 is rotated. The container 1 can be rotated so that the rotating shaft is close to the side of the container 1 with the oil-water separator 2. When the kitchen waste in the receiving cavity 11 is poured out, the oil on the surface will gather in the oil-water separator 2. The oil-water separator 2 has a limiting effect on the oil, so as to prevent the oil from being poured out with the waste when the container 1 is poured out. During the pouring process, the waste will stick to a very small amount of oil or not stick at all, so that when the kitchen waste poured out from the container 1 comes into contact with the subsequent waste processing components, the waste processing components will not stick to the oil, and the waste processing components are easy to clean.

[0028] In one embodiment, please refer to Figure 1 The oil-water separator 2 horizontally covers the width of the opening 12. In this embodiment, the oil-water separator 2 is roughly elongated, and its length is equal to the width of the opening 12. It can also be understood that the two ends of the oil-water separator 2 abut against the opposite cavity wall of the receiving cavity 11, so that when the kitchen waste in the receiving cavity 11 is poured out, the oil-water separator 2 can completely block the oil on the liquid surface, preventing the oil from being poured out along with the kitchen waste.

[0029] In one embodiment, the oil-water separation assembly further includes an oil-absorbing cloth (not shown in the figure), which is disposed on the side of the oil-water separator 2 facing away from the opening. In this embodiment, the oil-absorbing cloth can be made of polypropylene meltblown nonwoven fabric, which has extremely strong oil absorption properties and can quickly absorb oil stains several times its own weight. This material hardly absorbs water but has extremely strong oleophilic properties, making it suitable for cleaning oil stains on the water surface. The oil-absorbing cloth is disposed on the side of the oil-water separator 2 facing away from the opening, and a separation groove 21 for intercepting oil flow is formed between the side of the oil-water separator 2 facing away from the opening and the cavity wall of the receiving cavity 11. Therefore, it can also be understood that the oil-absorbing cloth is disposed on the groove wall of the separation groove 21. When the container 1 is rotated, the oil stains on the liquid surface of the receiving cavity 11 can flow to the oil-absorbing cloth, so that the oil-absorbing cloth can absorb the oil stains. By setting up an oil-absorbing cloth, this embodiment can absorb the oil stains on the liquid surface in a timely manner, preventing oil stains from entering the subsequent waste treatment components along with the kitchen waste.

[0030] In one embodiment, the oil-water separator 2 includes only a first intercepting plate 22. The first intercepting plate 22 and the cavity wall of the accommodating cavity 11 form the separation groove 21 described above. When the container 1 is rotated, the oil on the liquid surface of the accommodating cavity 11 can flow to the separation groove 21. Under the interception of the first intercepting plate 22, the oil can be separated from the kitchen waste, thereby achieving the effect of intercepting the oil.

[0031] In one embodiment, please refer to Figure 2 The oil-water separator 2 includes a first intercepting plate 22 and a second intercepting plate 23 connected at an angle. The first intercepting plate 22 is located between the second intercepting plate 23 and the bottom of the receiving cavity 11. The side of the first intercepting plate 22 facing the bottom of the receiving cavity 11 forms the aforementioned separation groove 21 between itself and the cavity wall of the receiving cavity 11. In this embodiment, it can be understood that a second intercepting plate 23 is added. In addition to the separation groove 21 formed between the first intercepting plate 22 and the cavity wall of the receiving cavity 11, a filter groove 24 is also formed between the first intercepting plate 22 and the second intercepting plate 23. The filter groove 24 and the separation groove 21 are separated by the first intercepting plate 22, and both have the same function. When the container 1 is emptying kitchen waste, the oil on the liquid surface of the container 11 will flow to the filter tank 24 and the separation tank 21 at the same time. The oil on the liquid surface will be blocked by the first intercepting plate 22 and the second intercepting plate 23. Compared with the embodiment with only one intercepting plate, this embodiment has a better oil filtration effect by setting two intercepting plates.

[0032] In one embodiment, please refer to Figure 2 The second intercepting plate 23 extends beyond the opening 12, which is located between the first intercepting plate 22 and the second intercepting plate 23. In this embodiment, the opening 12 can be understood as the top surface of the receiving cavity 11. When the receiving cavity 11 is full of liquid, the opening 12 is completely covered by the liquid. In this embodiment, the opening 12 is located in the filter tank 24 between the first intercepting plate 22 and the second intercepting plate 23. Therefore, even if the receiving cavity 11 is full of liquid, the oil on the liquid surface will still be located in the filter tank 24 and will not cross the intercepting tank 24, ensuring that the oil is intercepted and will not flow into the subsequent waste treatment components with the kitchen waste. In this embodiment, the liquid surface in the receiving cavity 11 can be intercepted by either the first intercepting plate 22 or the second intercepting plate 23 at any position.

[0033] In one embodiment, please refer to Figure 2The container 1 has a discharge notch 13 near the edge of the opening 12. The connection between the second intercepting plate 23 and the first intercepting plate 22 is located below the discharge notch 13 to avoid gaps between the connection and the discharge notch 13, preventing liquid from flowing out directly without being intercepted. The second intercepting plate 23 is inclined and angled downwards towards the discharge notch 13. Liquid intercepted by the second intercepting plate 23 can flow into the discharge notch 13 along the inclined surface of the second intercepting plate 23, and then be discharged through the discharge notch 13. In this embodiment, by providing the discharge notch 13, the liquid intercepted by the second intercepting plate 13 can be smoothly discharged from the discharge notch 13, preventing liquid from overflowing and spilling from both sides of the opening 12 during the process of dumping out with garbage, thus avoiding environmental pollution.

[0034] Secondly, this utility model also provides a waste interception device, including a fixed bracket 3, a drive assembly 4, and the aforementioned oil-water separation assembly. The container 1 of the oil-water separation assembly is rotatably connected to the fixed bracket 3 on the side near the oil-water separator 2. The drive assembly 4 is connected to the container 1 and can drive the container 1 to rotate. In this embodiment, the fixed bracket 3 mainly serves to support the oil-water separation assembly and also provides a rotatable platform for the oil-water separation assembly to facilitate waste disposal. The drive assembly 4 mainly provides the rotational power for the oil-water separation assembly, enabling it to rotate to dispose of waste, and allowing oil-water separation to occur during the waste disposal process.

[0035] In one embodiment, please refer to Figure 3 The drive assembly 4 includes a drive component 41, a rotating shaft 42, and a drive rod 43. The two ends of the rotating shaft 42 are rotatably connected to the fixed bracket 3. One end of the drive rod 43 is connected to the rotating shaft 42, and the other end is movably connected to the container 1. The drive component 41 is disposed in the container 1 and connected to the rotating shaft 42. In this embodiment, the drive component 41, rotating shaft 42, and drive rod 43 form a linkage relationship. When working, the drive component 41 can drive the rotating shaft 42 to rotate. When the rotating shaft 42 rotates, it can drive the drive rod 43 to rotate. When the drive rod 43 rotates, it can drive the container 1 to rotate, so that the container 1 can empty the waste. At the same time, oil and water are separated from the liquid surface. The side of the container 1 rotatably connected to the fixed bracket 3 and the mounting side of the oil-water separator 2 are on the same side of the container 1, so that when the container 1 is rotated, the oil on the liquid surface can be driven towards the oil-water separator 2, thereby intercepting the oil.

[0036] In one embodiment, please refer to Figure 3The driving component 41 includes a motor 411 and a driving gear 412 connected to each other. The motor 411 is located at the bottom of the container 1. The rotating shaft 42 has a driven gear 421, which meshes with the driving gear 412, and their rotation axes are perpendicular to each other. In this embodiment, when the motor 411 is working, it can drive the driving gear 412 to rotate. The driving gear 412 drives the driven gear 421 to rotate through meshing, and the driven gear 421 drives the rotating shaft 42 to rotate. The rotating shaft 42 drives the driving rod 43 to rotate, and the driving rod 43 drives the container 1 to rotate to dump garbage. Therefore, in this embodiment, it is only necessary to control the motor 411 to drive the driving gear 412 to rotate forward or backward to control the reciprocating rotation of the container 1. In addition, the driven gear 421 meshes with the driving gear 412, and their rotation axes are perpendicular to each other, so that the driving gear 412 and the motor 411 do not need to be installed on the same straight line as the rotating shaft 42, which helps to save installation space. In addition, a central control panel 45 is provided on the side wall of the container 1. The central control panel 45 is wirelessly connected to the motor 411 so as to control the motor 411 to work or not work, and to control the motor 411 to rotate forward or backward.

[0037] In one embodiment, please refer to Figure 3 The drive assembly 4 also includes a slide rail 44. The end of the drive rod 43 away from the rotating shaft 42 has a protrusion 431, which slides and rotates to engage with the slide rail 44. In this embodiment, when the drive rod 43 rotates, it acts on the slide rail 44 through the protrusion 431, thereby driving the container 11 to rotate. In other embodiments, the drive rod 43 can be rotatably connected to the container 1 without sliding, for example, the drive rod 43 can be rotatably connected to the container 1 through a pin. In this embodiment, the drive rod 43 is a telescopic rod. As the drive rod 43 drives the container 1 to rotate, the drive rod 43 also extends and retracts to adapt to the rotation of the container 1.

[0038] In one embodiment, please refer to Figure 1 The waste interception device also includes an interception box 5, which has an opening at the top and a discharge notch 13 above the opening, so that waste falling from the discharge notch 13 can fall into the interception box 5. The interception box 5 is equipped with a filter screen 51, which is used to intercept residue in the waste, so as to separate the liquid and solid in the waste, facilitating subsequent waste processing.

[0039] To better understand this utility model, the following is combined with... Figures 1 to 3 The technical solution of this utility model is described in detail below:

[0040] The oil-water separation component provided by this utility model has a container 1 with a receiving cavity 11 for holding kitchen waste to be processed. After the kitchen waste is placed in the receiving cavity 11 for a period of time, the oil in the kitchen waste can float to the surface. At this time, the container 1 is rotated to pour out the kitchen waste in the receiving cavity 11. The oil floating on the surface can be blocked by the oil-water separator 2 to intercept the oil. It can be seen that, compared with the prior art, the oil-water separation component of this application can separate oil and water during the process of pouring out kitchen waste. The oil remains in the container 1, and the kitchen waste poured out of the container 1 has little or no oil. The subsequent waste processing components will not be covered with a lot of oil, making cleaning convenient.

[0041] The specific embodiments of this utility model described above do not constitute a limitation on the scope of protection of this utility model.
