Description

Technical Field

[0001] The present invention relates to a dirt recycling device, and more particularly to an oil-water separation system. Background Art

[0002] The description in this part only provides background information related to the disclosure of the present invention and does not constitute prior art.

[0003] The oil-water separation system is a commonly used dirt recycling device, which can be used in kitchens, hotels, recycling centers, etc. Its main function is to separate the oil-water mixture into oil and water. There are various existing oil-water separation systems, and the main principle is to rely on the buoyancy of oil to separate the oil floating on the top surface of the oil-water mixture. For example, there are those that use a scraper to scrape off the oil or an electric device to transfer the oil.

[0004] In the existing oil-water separation system, the design of the oil-water separation pipeline is unreasonable. The pipelines for transporting liquids are distributed at the front and rear ends and other positions of the oil-water separation system. In some cases of use, it is not easy for the operator to step over the oil-water separation system to maintain the pipelines, which is extremely inconvenient to use and also affects the maintenance efficiency of the oil-water separation pipeline.

[0005] At the same time, due to the influence of the pipelines, in the kitchen use scenario, when the existing oil-water separator is used with a cooking range, because it occupies a relatively large area, it has a greater impact on the layout and use of the cooking range, occupying a relatively large functional space. And due to the obstruction of the cooking range, it is also difficult to step over the end of the oil-water separator for alignment and maintenance.

[0006] Furthermore, if the structural transmission of the oil-water separation system itself is unstable or restricted by unreasonable materials, the separation effect is average and the service life is poor, which further increases the maintenance difficulty.

[0046] Please refer to Figure 1-6 , which is an oil-water separation system for this embodiment. The oil-water separation system includes:

[0047] A base 1, the base 1 forms a first cavity 11, the first cavity 11 is used for placing an oil-water mixture, and the first cavity 11 has a first end and a second end that are oppositely arranged;

[0048] Oil-water separator 2, the oil-water separator 2 includes a separation baffle 21 and an oil-water separation mechanism 22. The separation baffle 21 is arranged above the first cavity 11 of the base, and at least part of the bottom of the separation baffle 21 is arranged inside the first cavity 11. The top surface side of the separation baffle 21 facing away from the first cavity 11 has a second cavity 211. The oil-water separation mechanism 22 includes a driving motor 222, a driving shaft 223, a drum 223, and a scraper 224. The driving motor 222 is fixed on the separation baffle 21, the output end of the driving motor 222 is connected to the driving shaft 223, the driving shaft 223 axially penetrates through the drum 223 along the axis of the drum 223 and is fixedly connected to the drum 223. The separation baffle 21 has an opening. Below the opening is the first cavity area 11, and above the opening is the second cavity 211 area. The drum 223 is arranged at the position between the first cavity 11 and the second cavity 211 at the opening. The scraper 224 has a first side and a second side arranged opposite to each other. The first side of the scraper 224 is arranged in contact with the generatrix of the drum 223, and the second side of the scraper 224 inclines downward towards the direction of the second cavity 211. Wherein, the outer wall of the drum 223 is made of stainless steel. The driving motor 222 is used to drive the drum 223 to rotate through the driving shaft 223. The drum 223 is used to lift the oil floating on the surface of the oil-water mixture placed in the first cavity 11 and scrape it into the second cavity 211 by the scraper 224;

[0049] Oil collection tank 3, the oil collection tank 3 is arranged on one side of the oil-water separator 2 and is communicated with the second cavity 211;

[0050] First pipeline 7, second pipeline 8. The first end of the first pipeline 7 is communicated with the top position of the first cavity 11, and the second end of the first pipeline 7 faces the second end of the base 1 and is located outside the base 1, that is, the position of the final sewage discharge port 13. The first end of the second pipeline 8 is communicated with the bottom position of the first cavity 11, and the second end of the second pipeline 8 can be communicated with the first pipeline 7. The base 1 is also provided with an inlet pipeline 12 for pouring the oil-water mixture into the first cavity 11 at the second end of the first cavity 11;

[0051] Material platform 5, the material platform 5 is installed on the top of the oil-water separator 2 through an installation frame 52. The installation frame 52 is used to form a gap between the material platform 5 and the oil-water separator 4 and make the top surface of the material platform 5 have a preset height.

[0052] During the above-mentioned use process, when in use, the operator only needs to pour the oil-water mixture from the top into the first cavity 11 of the base 1, so that the first cavity 11 is filled with the oil-water mixture, and by virtue of the physical properties, wait for the oil and water to separate. Among them, the oil with a lower density floats on the upper layer of the water. During the process of gradually adding more oil-water mixture, the liquid level of the oil in the upper layer rises until the oil surface touches the bottom of the drum 223 in the oil-water separation mechanism 22. At this time, the oil-water separation mechanism 22 is driven to operate, and the drum 223 rotates. By virtue of the viscosity of the oil on the stainless-steel surface of the drum 223 and the inertia of rotation, part of the oil is rotated from the bottom position of the drum 223 to the top position of the drum 223. When it rotates to the position of the scraper 224, since the scraper 224 is closely attached to the drum 223, the oil on the drum 223 near the contact position is scraped off by the scraper 224 and guided into the second cavity 211 of the separation baffle 21 on the second side of the scraper 224, and continuous operation is maintained, realizing the collection of oil into the second cavity 211.

[0053] During oil-water separation, the present invention fully utilizes the gravitational force and inertia of the oil-water mixture and the material to realize the collection of oil in the oil-water mixture. Since it is difficult for the stainless-steel drum 223 to lift water, finally only the separated water remains in the first cavity 11 of the base 1, realizing the complete separation of oil and water. Specifically, in this embodiment, since the stainless-steel drum 223 is similar to or the same as the materials of the base 1 and the separation baffle 21, it is cheap and easy to manufacture, and the processing difficulty is low. At the same time, compared with the existing drum 223 generally made of acrylic material, it has better wear resistance and a longer service life. At the same time, in this embodiment, the driving motor 222 is directly connected to the drum 223 by means of the driving shaft 223 for output, rather than the existing method using a coupling, etc. Therefore, the rotation control of the drum 223 can achieve better coaxiality, rotate more stably, and has better compactness, saving more space.

[0054] During use, the operator only needs to pour the oil-water mixture into the first cavity 11 from the inlet pipe 12, and the liquid level gradually rises. When the liquid level rises to a sufficient height, start the oil-water separation mechanism 22 in the oil-water separator 2 to operate, separate the oil at a relatively high liquid level in the first cavity 11 into the second cavity 211, and then the second pipe 8 can be opened. At this time, the heavier water at the bottom of the first cavity 11 flows into the second pipe 8 from the first cavity 11 and flows towards the first pipe 7 along the second end direction until it flows out from the outlet of the first pipe 7 to the outside of the base 1 and is collected and discharged. At the same time, when the liquid level is too high, it can be collected and discharged along the direction of the second end from the first end exceeding the highest position of the first end of the first pipe 7, thus restricting the liquid level height in the first cavity 11. Therefore, the first pipe 7 for restricting the liquid level height and the second pipe 8 for discharging water can each realize their cleaning or liquid discharging functions. Among them, the first pipe 7 is used to receive the discharge of the liquid at the top of the first cavity 11, and the second pipe 8 is used to receive the discharge of the water at the bottom of the first cavity 11. Moreover, the outlet positions of the inlet pipe 12, the first pipe 7, and the second pipe 8 are all set on the same side of the base 1. The operator can maintain the oil-water separation pipeline structure without having to cross the oil-water separation system, significantly improving the maintainability and working efficiency.

[0055] Based on the present invention, the operator only needs to place the base 1 at a position between the first stove and the second stove, and at the same time connect one inlet pipe 12 of the oil-water separator 2 to the first stove and the other inlet pipe 12 to the second stove, and make the sewage outlet 13 face the side where the operator is convenient to move. Then, by adjusting the mounting frame 52, the material table 5 above the oil-water separator 2 is placed at a preset position so that the top surface of the material table 5 is flush with the first stove and the second stove. During use, the dirt is poured into the oil-water separator 2 from the first stove and the second stove on both sides, and the oil-water separator 2 is started to process the dirt, and the processed dirt is discharged through the sewage outlet 13. When maintenance or repair is needed, the operator directly removes the inlet pipe 12 or the sewage outlet 13 at the second end position. During the above use process, by setting a material table on the oil-water separator 2, and the material table 5 realizes the leveling with the stoves on both sides by means of the mounting frame 52 with adjustable height, and makes up for the function of the original oil-water separator 2 occupying space. Moreover, the pipeline outlets of the oil-water separator 2 itself are all set on the same side. Specifically, the inlet pipe 12 or the sewage outlet 13 is set at the position of the second end. The operator can maintain the oil-water separator 2 itself without having to step over the oil-water separator 2, greatly improving the practicality of matching with the stove, and by means of the material table 5 filling the space of the two stoves themselves, greatly expanding the functionality.

[0056] The first side of the scraper 224 in contact with the drum 223 is made of nylon. Specifically, considering the worn nature of nylon, the main body of the scraper 224 can be set as a stainless-steel metal plate connected to the separation baffle 21 by welding or fasteners, while the second end of the scraper 224 is connected to a nylon plate of matching size by means of a slot or fastener snap, making the nylon plate itself easy to replace and easy to maintain later.

[0057] The outer wall of the drum 223 is made of polished stainless steel. The polished stainless-steel material has higher material strength and longer service life compared with the traditional acrylic plastic material. Compared with other rough surface metal materials without polishing, it has stronger adhesive force to oil.

[0058] The axial length of the drum 223 matches the width dimension of the second cavity 211. Specifically, in this embodiment, the separation baffle 21 encloses a second cavity 211 space equivalent to the axial length of the drum 223, which has an enclosed wall surface, so that the oil liquid level height in the second cavity 211 can be maximized, the pressure at the bottom of the oil is higher, and the aggregation and export speed of the oil can be enhanced to the greatest extent.

[0059] An oil outlet hole 212 is provided at the bottom of the second cavity 211, and the oil outlet hole 212 is connected to the waste oil collection box. Specifically, the oil outlet hole 212 at the bottom of the second cavity 211 is provided at the corner position of the second cavity 211. Therefore, when a certain liquid level height of oil has accumulated in the second cavity 211, the oil hole 22 at the corner position can drain all the oil in the second cavity 211 more cleanly. In another embodiment, the second cavity 211 can be set as an inclined plane sloping towards the oil outlet hole 212 to enhance the oil drainage efficiency more quickly.

[0060] The oil-water separation system further includes a screen 4. The screen 4 is arranged above the base 1, and the bottom of the screen 4 faces the first cavity 11. The screen 4 is used for the first preliminary screening of the oil-water mixture. The operator pours the oil-water mixture into the screen 4 from the top of the screen 4, so that the screen 4 filters out some of the residues to prevent them from floating to the alignment of the drum 223 and causing wear.

[0061] The mounting bracket 52 includes a sleeve 521, a connecting column 522, and a setscrew. The sleeve 521 is fixedly connected to the base 1, the connecting column 522 is fixedly connected to the material table 5, the connecting column 522 is installed in the sleeve 521, the setscrew is arranged at the bottom of the sleeve 521, and the setscrew is used to jack up the connecting column 522 in the sleeve 521. Specifically, during installation, first, the material table 5 is initially installed in place, and the connecting column 522 is installed in the sleeve 521. At this time, the material table 5 is at the lowest position. Then, by rotating the setscrew, which is threadedly connected to the bottom of the sleeve 521, the connecting column 522 in the sleeve 521 can be jacked up from the bottom. Therefore, the height adjustment of the connecting column 522 can be achieved. Specifically, by means of the above adjustment method, the material table 5 can be adjusted to be flush with the corresponding first cooking stove or the second cooking stove to meet the preset usage conditions. The sleeve 521 is fixedly connected to the side wall of the base 1, and the connecting column 522 is fixedly connected to the bottom of the material table 5. Therefore, in this embodiment, the sleeve 521 does not hinder the opening of the structure on the top surface of the oil-water separator 2 (such as the inspection door 14, etc.), and the connecting column 522 does not hinder the peripheral space of the material table 5, which can maximize the area of the material table 5. The number of the mounting brackets 52 is four, and the four mounting brackets 52 are respectively arranged at the four corners of the combined device of the base 1 and the material table 5. That is to say, the base 1 and the material table 5 in this embodiment are generally arranged in a rectangular structure, and the four-corner support structure can achieve a relatively stable maintenance state.

[0062] The top surface of the oil-water separator 2 has an inspection door 14. When the inspection door 14 is fully opened, it has a first height, and the clearance height between the material table 5 and the oil-water separator 2 is not less than the first height of the inspection door 14. That is to say, by setting the mounting bracket 52, at least the operator can open the inspection door 14 without obstruction, so as to facilitate the maintenance of the inside of the oil-water separator 2 (such as cleaning oil residues, etc.).

[0063] The top of the material table 5 has a folding door 51, and the folding door 51 is used to fold and open along the first end direction of the material table. In the closed state of the folding door 51, the top surface of the folding door 51 can be used as a tabletop for cooperation with the cooking stove. When the folding door 51 is opened, its interior can be used as a storage space for collecting materials, kitchen utensils, etc.

[0064] The first end of the first pipeline 7 and the first end of the second pipeline 8 are connected and communicated with the position near the first end of the first cavity 11. Specifically, since the positions where the liquid enters the first pipeline 7 and the second pipeline 8 are both at the first end, and the position where the final liquid level flows out is at the second end, it is possible to make it more difficult for residues to accumulate at the first end position in the overall first cavity 11. And at the second end position of the first cavity 11, which is also on the side closer to the operator's position, it is easier to perform manual cleaning. The connection between the first end of the second pipeline 8 and the first cavity 11 is opened on the bottom surface of the base 1. With this setting in this embodiment, the first end of the second pipeline 8 releases the liquid in the first cavity 11 more cleanly and thoroughly. The first pipeline 7 and the second pipeline 8 extend along the direction parallel to the first end to the second end of the first cavity 11. Based on this embodiment, a more unobstructed liquid flow path can be formed, and it is easier to process, saving costs. The connection between the first pipeline 7 and the top of the first cavity 11 has a collection box 71 arranged covering the width direction of the first cavity 11. Specifically, through the setting of the collection box 71, it is possible to avoid the unsmooth liquid inlet at the first end of the first pipeline 7. It should be noted that generally, the liquid that may enter the collection box 71 is oil, and the oil exceeding the preset liquid level height can be effectively collected. A switch valve 6 is provided at the connection between the first pipeline 7 and the second pipeline 8. During normal use, the switch valve 6 can be closed, and at this time, the liquid level height in the first cavity 11 can be maintained. When sewage discharge is required, the switch valve 6 can be opened so that part of the water at the bottom position of the first cavity 11 is discharged to achieve the control of the liquid level. The connection between the first pipeline 7 and the second pipeline 8 extends along the direction perpendicular to the first end to the second end of the first cavity 11. Based on this embodiment, it has a lower manufacturing cost, a shorter pipeline, a fast flow rate, and a small resistance to the liquid.
