Description

Technical Field

[0001] This application relates to oil separators, and more particularly to an oil separator draining device. Background Technology

[0002] Food wastewater contains a large amount of animal and vegetable oils. If it is discharged into the municipal pipe network without being treated, it will not only clog and corrode the pipes, but also affect the water quality of the sewage treatment plant at the end. Therefore, oil separators that can separate impurities, oil and water from oily wastewater have become an essential facility for various hotels, restaurants, high-end guesthouses and commercial restaurants.

[0003] In existing technologies, after oil separators separate grease from wastewater, most rely on manual control of valves to discharge the grease floating on top of the wastewater, achieving separate collection of grease and wastewater. This has a low degree of automation and requires manual removal of the separated grease every so often, which is not conducive to long-term use. Utility Model Content

[0004] The purpose of this application is to provide an oil separator draining device that has the advantage of automatically collecting the separated grease. This solves the problem that most oil separators rely on manual valve control to drain grease, resulting in low automation and requiring manual draining of the separated grease every so often, which is not conducive to long-term use.

[0005] This application provides an oil separator draining device with the following technical solution: It includes an oil separator tank, one side of which has a through hole and is fixedly connected to a water inlet pipe; the side of the oil separator tank away from the water inlet pipe has a through hole and is fixedly connected to a water outlet pipe; several oil-separating plates are fixedly connected to the inner walls of two sides of the oil separator tank; several flow-damping plates are fixedly connected between the inner walls of two sides of the oil separator tank; and a deep filter plate is fixedly connected to the inner walls of two sides of the oil separator tank. A first liquid level sensor is fixedly connected to the wall. Oil drain pipes are provided on the side of the oil separator and the side of the deep filter plate. One side of the oil separator has a through hole adapted to the oil drain pipe and is fixedly connected to the oil drain pipe. A plug is provided inside the oil drain pipe. An electric push rod is fixedly connected to the side of the oil separator. A moving plate is fixedly connected to the output shaft of the electric push rod. A fixed oil tank is fixedly connected to the side of the oil separator. A movable oil tank is provided inside the fixed oil tank. A drain pipe is connected to the side of the oil separator.

[0006] By adopting the above technical solution, the level of the separated grease can be sensed by the first liquid level sensor during use. When the grease level reaches the standard, the moving plate can be moved by the electric push rod, which in turn moves the plug, causing the plug to leave the oil drain pipe. This allows the grease separated from the wastewater to be discharged into the interior of the movable oil tank through the oil drain pipe, completing the automatic collection of grease and completely separating the grease from the wastewater. This solves the problem that most oil separators rely on manual control of valves to discharge grease, resulting in low automation and requiring manual discharge of separated grease at regular intervals, which is not conducive to long-term use.

[0007] Preferably, a rubber pad is fixedly connected to the end of the oil drain pipe away from the oil separator, and one end of the plug is tapered;

[0008] By adopting the above technical solution, the conical plug can enhance the sealing effect on the oil drain pipe, and the rubber gasket can prevent the appearance of tiny gaps between the plug and the oil drain pipe.

[0009] Preferably, a fixing plate is fixedly connected between two adjacent plugs, and the movable plate is fixedly connected to one of the fixing plates;

[0010] By adopting the above technical solution, the movable plate can move the fixed plate, and multiple fixed plates can be connected to multiple plugs, so that when the movable plate moves, it drives multiple plugs to move.

[0011] Preferably, the top of the fixed oil tank has a through hole and a soft sleeve is fixedly connected thereto, and the movable plate is located inside the soft sleeve and is fixedly connected to the soft sleeve;

[0012] By adopting the above technical solution, the soft sleeve is always connected to the moving plate. When the moving plate moves, the soft sleeve deforms itself, thereby sealing the fixed oil tank and preventing the odor of the grease from escaping.

[0013] Preferably, a protective shell is fixedly connected to the top of the fixed oil tank, and the electric push rod is located inside the protective shell;

[0014] By adopting the above technical solution, the protective shell can protect the electric linear actuator and prevent external environmental factors from affecting its use.

[0015] Preferably, a second liquid level sensor is fixedly connected to the side of the movable plate, and the detection end of the second liquid level sensor is located inside the movable oil tank;

[0016] By adopting the above technical solution, the second liquid level sensor can detect the grease inside the movable oil tank, thereby preventing excessive grease from overflowing into the fixed oil tank.

[0017] Preferably, a first oil pipe is slidably connected to the interior of one side of the fixed oil tank, and a second oil pipe is fixedly connected to a through hole on one side of the movable oil tank, with the first oil pipe movably connected to the second oil pipe.

[0018] By adopting the above technical solution, the movable connection between the first oil pipe and the second oil pipe can be used as needed. The first oil pipe can be opened to allow grease to flow to the outside through the first oil pipe and the second oil pipe. Alternatively, the fixed oil tank can be opened directly to separate the first oil pipe and the second oil pipe and remove the entire movable oil tank, thus meeting the diverse needs of users.

[0019] Preferably, a support plate is fixedly connected to the inner walls of both sides of the oil separator, a positioning plate is provided on the top of the support plate, and a filter cake box is fixedly connected between the two positioning plates.

[0020] By adopting the above technical solution, the filter cake box can filter the residue of wastewater. The support plate supports the filter cake box through the positioning plate, and the positioning plate makes it convenient for users to remove the filter cake box.

[0021] In summary, this application includes at least one of the following beneficial technical effects:

[0022] 1. This oil separator draining device, through the arrangement of a first liquid level sensor, an electric push rod, a drain pipe, a moving plate, a fixed plate, a plug, a rubber pad, and a movable oil tank, enables the device to sense the liquid level of the separated grease through the first liquid level sensor during use. When the grease level reaches the target, the electric push rod moves the moving plate, which in turn moves the fixed plate, causing the plug to move away from the drain pipe. This allows the grease separated from the wastewater to be drained into the movable oil tank through the drain pipe, completing the automatic collection of grease and completely separating the grease from the wastewater. This solves the problem that most oil separators rely on manual valve control to drain grease, resulting in low automation and requiring manual draining of separated grease at regular intervals, which is not conducive to long-term use.

[0023] 2. This oil separator draining device, through the arrangement of a fixed oil tank, a movable oil tank, a second liquid level sensor, a first oil pipe, and a second oil pipe, enables the device to collect the separated grease through the movable oil tank during use. The collected grease can be monitored by the second liquid level sensor to detect the grease level. This allows the user to transfer the grease to the fixed oil tank when there is too much grease. During transfer, the first oil pipe can be opened to allow the grease to flow to the outside through the first and second oil pipes, or the fixed oil tank can be opened directly to separate the first and second oil pipes and remove the entire movable oil tank, thus meeting the diverse needs of the user.

[0031] The following is in conjunction with the appendix Figure 1 - Appendix Figure 5 This application will be described in further detail below.

[0032] Example 1: An oil separator draining device, referring to... Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5The system includes an oil separator 1, with a through hole on one side of the oil separator 1 and a water inlet pipe 2 fixedly connected thereto. An outlet pipe 3 is fixedly connected to the side of the oil separator 1 away from the water inlet pipe 2. Several oil-separating plates 4 are fixedly connected to the inner walls of both sides of the oil separator 1. Several flow-damping plates 5 are fixedly connected between the inner walls of both sides of the oil separator 1. A deep filter plate 6 is fixedly connected to the inner walls of both sides of the oil separator 1. A first liquid level sensor 7 is fixedly connected to the inner wall of one side of the oil separator 1. Oil drain pipes 8 are provided on the sides of both the oil-separating plates 4 and the deep filter plate 6. An outlet pipe 8 is located on one side of the oil separator 1. A suitable through-hole is used to fix and connect the oil drain pipe 8. The oil drain pipe 8 has a plug 10 inside. An electric push rod 12 is fixedly connected to the side of the oil separator 1. The output shaft of the electric push rod 12 is fixedly connected to a moving plate 13. A fixed oil tank 17 is fixedly connected to the side of the oil separator 1. The fixed oil tank 17 has a movable oil tank 18 inside. A drain pipe 21 is connected to the side of the oil separator 1. A rubber pad 9 is fixedly connected to the end of the oil drain pipe 8 away from the oil separator 1. One end of the plug 10 is conical. A fixed plate 11 is fixedly connected between two adjacent plugs 10. The moving plate 13 is fixedly connected to one of the fixed plates 11. The fixed oil tank 1... The top of the oil tank 17 has a through hole and a soft sleeve 14 is fixedly connected thereto. The movable plate 13 is located inside the soft sleeve 14 and is fixedly connected to the soft sleeve 14. The top of the fixed oil tank 17 is fixedly connected to a protective shell 15. The electric push rod 12 is located inside the protective shell 15. Support plates 22 are fixedly connected to the inner walls of both sides of the oil separator 1. The top of the support plate 22 is provided with a positioning plate 23. A filter cake box 24 is fixedly connected between the two positioning plates 23. Through the arrangement of the first liquid level sensor 7, electric push rod 12, oil drain pipe 8, movable plate 13, fixed plate 11, plug 10, rubber soft pad 9 and movable oil tank 18, the device is ready for use. The system can detect the level of the separated grease through the first liquid level sensor 7. When the grease level reaches the target, the moving plate 13 can be moved by the electric push rod 12, which in turn causes the fixed plate 11 to move the plug 10, thereby causing the plug 10 to leave the oil drain pipe 8. In this way, the grease separated from the wastewater is discharged into the interior of the movable oil tank 18 through the oil drain pipe 8, completing the automatic collection of grease and completely separating the grease from the wastewater. This solves the problem that most oil separators rely on manual control of valves to discharge grease, resulting in low automation and requiring manual discharge of separated grease every once in a while, which is not conducive to long-term use.

[0033] Example 2: An oil separator draining device, referring to... Figure 4 , Figure 5A second liquid level sensor 16 is fixedly connected to the side of the movable plate 13. The detection end of the second liquid level sensor 16 is located inside the movable oil tank 18. A first oil pipe 19 is slidably connected to the inside of one side of the fixed oil tank 17. A through hole is opened on one side of the movable oil tank 18 and a second oil pipe 20 is fixedly connected thereto. The first oil pipe 19 is movably connected to the second oil pipe 20. Through the arrangement of the fixed oil tank 17, the movable oil tank 18, the second liquid level sensor 16, the first oil pipe 19, and the second oil pipe 20, the device can be controlled by the movable oil tank 17 during use. The movable oil tank 18 collects the separated grease, and the level of the collected grease can be detected by the second liquid level sensor 16. This allows the user to transfer the grease to the fixed oil tank 17 when there is too much grease inside. When transferring, the user can open the first oil pipe 19 to allow the grease to flow to the outside through the first oil pipe 19 and the second oil pipe 20, or directly open the fixed oil tank 17, separate the first oil pipe 19 and the second oil pipe 20, and remove the movable oil tank 18 completely to meet the diverse needs of the user.

[0034] The implementation principle of this application embodiment is as follows: When in use, the device is fixed in a certain location, and the inlet pipe 2 is connected to the external wastewater discharge point. The outlet pipe 3 is also connected to the drain pipe. Then the device can be used. During use, wastewater enters the oil separator 1 through the inlet pipe 2. The wastewater then falls into the filter cake box 24, where it filters the residue in the wastewater. The filtered wastewater falls to the bottom of the oil separator 1 and is blocked by the flow buffer 5. Some of the wastewater then passes through the flow buffer 5, and the flow rate is slowed by the flow buffer 5. Afterward, the wastewater passes through multiple... The flow-slowing plate 5 is used until the wastewater comes into contact with the deep filter plate 6. The wastewater passes through the deep filter plate 6 and enters the interior of the outlet pipe 3, and is discharged to the outside. As the wastewater flows slowly inside the oil separator 1, the grease in the wastewater, being lighter than the wastewater, floats on top of the wastewater. The floating grease is blocked by the oil separator 4 and does not flow with the wastewater inside and outside the oil separator 1. As the amount of floating grease increases, the grease level begins to rise. Then the grease enters the interior of the oil drain pipe 8, but the interior of the oil drain pipe 8 is sealed by the plug 10, and the grease stops flowing until the first level sensor 7 detects the grease. Then, the first liquid level sensor 7 activates the electric push rod 12. The electric push rod 12 then moves the moving plate 13, which in turn moves the fixed plate 11, causing multiple plugs 10 to move simultaneously. After the plugs 10 move, they disengage from the drain pipe 8, allowing the grease inside the drain pipe 8 to flow and fall into the movable oil tank 18, thus completing the automatic collection of grease. When the grease level drops, the first liquid level sensor 7 activates the electric push rod 12, causing the plugs 10 to seal the drain pipe 8, preventing wastewater from entering the movable oil tank 18. When the movable oil tank 18 has collected enough grease... After the grease is collected, the second liquid level sensor 16 detects its presence and alerts the outside world, prompting staff to promptly transfer the large amount of grease collected. During transfer, staff can open the first oil pipe 19 to allow the grease to enter the first oil pipe 19 through the second oil pipe 20, thus completing the transfer. Alternatively, the fixed oil tank 17 can be opened during transfer, and then the second oil pipe 20 can be closed. After closing, the first oil pipe 19 can be pulled to detach from the second oil pipe 20, allowing staff to move out the movable oil tank 18 and transfer the grease together with the movable oil tank 18.
