Description

Technical Field

[0001] This utility model relates to the field of oil-water separation equipment technology, and in particular to a commercial oil-water separator with automatic temperature control function. Background Technology

[0002] Oil-water separators are widely used in industries such as catering and food processing to separate grease and water from oily wastewater. With technological advancements, oil-water separators have gradually become automated, greatly improving their processing efficiency and ease of operation. However, existing oil-water separators still have certain shortcomings in temperature control, affecting separation efficiency and equipment stability.

[0003] Currently, most oil-water separators on the market use manual heating, which is cumbersome to operate and has low temperature control accuracy. While some high-end equipment has automatic control functions, its temperature control system is complex, costly, and difficult to maintain.

[0004] On the other hand, most existing oil-water separators only remove grease from water through gravity sedimentation, which is difficult to completely remove. Some oil-water separators further separate oil and water by heating the water in the wastewater to vaporize it, but this method is complex in structure and expensive. Utility Model Content

Detailed Implementation

[0019] To make the technical problems, technical solutions and advantages of this utility model clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.

[0020] like Figure 1 As shown, a commercial oil-water separator with automatic temperature control function includes a separator body, a heating unit, and a control unit.

[0021] Specifically, the separator body includes a housing 1, with an inlet and an outlet respectively provided on the side walls at the left and right ends of the housing 1. The housing 1 is provided with a first baffle 2 and a second baffle 3, which divide the housing 1 into three chambers connected at the bottom: a first chamber, a second chamber, and a third chamber.

[0022] In this embodiment, the inlet and the outlet are respectively provided with an inlet pipe 4 and an outlet pipe 5. The sewage to be treated enters the interior of the tank 1 through the inlet pipe 4 and flows through the first chamber, the second chamber and the third chamber in sequence, and is finally discharged through the outlet pipe 5.

[0023] The first chamber is equipped with a filter screen 6. Wastewater to be treated enters the first chamber, is filtered by the filter screen 6, and then enters the second chamber from the bottom of the first baffle 2. Figure 1 As shown, the filter screen 6 is formed by welding steel wire mesh, and hooks 7 are provided on both sides of the filter screen 6. The end of the hook 7 away from the filter screen is bent outward to form a bent part.

[0024] In this embodiment, the filter screen 6 can filter the sewage entering the first chamber to remove impurities, and the mesh size of the wire mesh can be adjusted according to the size of the impurities. Furthermore, the hook allows for quick lifting of the filter screen 6 to clean any remaining impurities.

[0025] After filtration, the wastewater enters the second chamber, where oil-water separation takes place. An oil drain port is located on the side wall of the second chamber, and an oil drain pipe is installed on the drain port to discharge the separated grease.

[0026] After oil-water separation is completed in the second chamber, the wastewater enters the third chamber from the bottom of the second baffle 3. Furthermore, an oil-absorbing assembly is installed inside the third chamber. This assembly includes a winding motor (not shown), a take-up shaft 8, a release shaft 9, several support shafts 10, and filter paper 11. The release shaft 9, take-up shaft 8, and support shafts 10 are vertically arranged between two opposite side plates of the third chamber and are parallel to each other. The winding motor 8 is located on the outer wall of the third chamber and connected to the take-up shaft 8. The filter paper 11 is mounted on the release shaft 9, with one end of the filter paper 11 passing over several support shafts 10 and connecting to the take-up shaft 8. The width of the filter paper 11 is the same as the length of the release shaft 9, take-up shaft 8, and support shafts 10.

[0027] In this embodiment, the oil-absorbing paper 11 is rotatably sleeved on the paper roll shaft, and the oil-filtering paper passes around several support shafts in sequence and is connected to the paper take-up shaft. Thus, the sewage entering the third chamber can be further degreased by the oil-filtering paper, and the oil-filtering paper can be quickly replaced when the oil-absorbing paper is dirty.

[0028] The heating unit includes a power supply and a heating element 12. The heating element is disposed inside the bottom plate of the housing between the first baffle 2, the second baffle 3, and the first baffle 1 and the second baffle 2. The power supply provides power to the heating element 12. The heating element 12 can rapidly heat the sewage inside the second chamber, thereby improving the oil-water separation efficiency. Preferably, the heating element is a resistance wire.

[0029] The control unit includes a host computer, and a temperature sensor 13 and a liquid level sensor 14 connected to the host computer. The temperature sensor 13 is located inside the second chamber and is used to monitor the water temperature inside the second chamber and send the monitored temperature information to the host computer. The liquid level sensor 14 is located inside the third chamber and is used to monitor the liquid level height inside the third chamber and send the monitored liquid level information to the host computer. The host computer controls the heating unit and the oil suction assembly respectively based on the received temperature information and liquid level information.

[0030] During oil-water separation, wastewater enters the first chamber through the inlet pipe, is filtered by the filter screen, and then enters the second chamber from the bottom of the first baffle. Oil-water separation occurs in the second chamber, and the separated grease is discharged through the oil drain port. The separated wastewater enters the third chamber from the bottom of the second baffle. In the third chamber, the wastewater is further filtered by oil-absorbing paper to remove grease before being discharged through the drain pipe. During this process, a temperature sensor 13 installed inside the second chamber monitors the water temperature in real time. When the temperature is too low, the main unit controls the heating element to heat the wastewater in the second chamber, thereby improving the oil-water separation efficiency. On the other hand, a level sensor installed in the third chamber monitors the liquid level in real time. When the liquid level is too high (indicating dirty oil-absorbing paper and inability to discharge filtered wastewater promptly), the main unit sends a message to the winding motor to replace the oil-absorbing paper.

[0031] This commercial oil-water separator, through the inclusion of a heating unit and a control unit, can precisely control the temperature during oil-water separation. Furthermore, the oil-absorbing component in the third chamber further removes grease from the wastewater, resulting in more thorough oil-water separation. In addition, it can automatically replace the oil-absorbing paper, making operation convenient and highly automated.
