Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of oil-water separation equipment, and in particular relates to a special water tank structure for oil-water separation. Background Art
[0002] Oil-water separation is mainly based on the density difference or chemical properties of water and oil, using the principle of gravity sedimentation or other physical and chemical reactions to remove impurities or complete the separation of oil and water.
[0003] Since the conventional simple oil-water separation water tank has the problem that after the water is drained, the oil in the upper layer continues to be discharged from the drainage channel, thus causing the drainage pipe of the conventional simple oil-water separation water tank to be easily mixed with oil.
[0004] To this end, we proposed a special water tank structure for oil-water separation to solve the above problems. Utility Model Content
[0005] The utility model aims to solve the problem that the drainage pipe of the conventional simple oil-water separation water tank is easily mixed with oil, and proposes a special water tank structure for oil-water separation.
[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:
[0007] A special water tank structure for oil-water separation includes a water tank, the upper part of which is covered with a sealing cover, the upper part of which is fixedly connected with a water injection valve and an oil drain pipe, the lower part of which is fixedly connected with a drain pipe, and the upper part of the drain pipe is flush with the oil drain pipe. The oil and water are discharged into the water tank through the water injection valve, and when the oil and water level is higher than the oil drain pipe, the water at the lower part of the drain pipe enters the drain pipe and is discharged outward through the drain pipe, and the oil at the upper part is discharged through the oil drain pipe. When the water level is lower than the drain pipe and the oil drain pipe, the discharge is stopped to prevent the oil from being discharged from the drain pipe, thereby reducing the possibility of oil discharge from the drain pipe.
[0008] Preferably, the upper end of the sealing cover is fixedly connected with a shaft frame and an exhaust nozzle, the exhaust nozzle penetrates the sealing cover, and the shaft frame is rotatably connected with a dust shield cover, which movably covers the exhaust nozzle. The dust shield cover is used to block the upper end of the exhaust nozzle to prevent dust from entering the water tank. When the water injection valve injects oil and water, the gas is discharged outward through the exhaust nozzle, which is convenient for exhaust and dust prevention.
[0009] Preferably, a drain valve is fixedly connected to the lower part of the water tank, and the drain valve runs through the water tank. When the sewage in the water tank needs to be discharged, the drain valve is opened to empty the oil, water and sewage in the water tank, so as to facilitate cleaning of the water tank.
[0010] Preferably, the water tank includes a box body, a baffle and an oil baffle, the baffle is fixedly connected to the inner end of the box body, the oil baffle is evenly fixedly connected to the inner end of the box body, and there is a gap between the lower ends of the baffle and the oil baffle and the lower end of the box body. After the water injection valve injects oil and water into the box body, the baffle is used to block the oil and water, so that the oil and water flow from the lower side of the baffle to the oil baffle, and the oil baffle is used to block the flow of the upper layer of oil until the oil submerges the oil baffle and is discharged through the oil drain pipe, so that the oil can float upward smoothly.
[0011] Preferably, the water injection valve comprises a water valve, a first swing rod and a float, wherein the first swing rod is fixedly connected to the knob of the water valve, and the float is fixedly connected to the lower part of the first swing rod. When the oil and water level contact the float, the oil and water act on the float, so that the float acts upward on the first swing rod, so that the first swing rod drives the knob of the water valve to rotate until the water valve is closed, thereby facilitating automatic control of the oil and water level of the water tank.
[0012] Preferably, a limit rod is provided inside the water tank, and the limit rod is fixedly connected to the tank body. The limit rod is used to pad under the first swing rod to prevent the first swing rod from sagging straight down, so as to facilitate the floating block to float upward smoothly.
[0013] Preferably, the dust shielding cover comprises a cover plate, a second swing rod and a rotating sleeve, wherein the second swing rod is fixedly connected between the cover plate and the rotating sleeve. When pressure is generated at the lower part of the cover plate, the cover plate tilts upward to discharge the gas in the exhaust nozzle.
[0014] In summary, the technical effects and advantages of the utility model are as follows:
[0015] 1. Drain the oil and water into the water tank through the water filling valve. When the oil and water level is higher than the oil drain pipe, allow the water to enter the drain pipe from the lower part and be discharged outward through the drain pipe, and discharge the oil from the upper part through the oil drain pipe. When the water level is lower than the drain pipe and the oil drain pipe, stop discharging to prevent the oil from being discharged from the drain pipe and reduce the possibility of oil discharge from the drain pipe.
[0016] 2. Use the dust cover to block the upper end of the exhaust nozzle to prevent dust from entering the water tank. When the water filling valve injects oil and water, the gas is discharged outward through the exhaust nozzle, which is convenient for exhaust and dust prevention.
[0017] 3. When the sewage in the water tank needs to be discharged, open the drain valve and drain the oil, water and sewage in the water tank to facilitate cleaning of the water tank.
[0018] 4. After the water injection valve injects oil and water into the box, use the baffle to block the oil and water, so that the oil and water flow from the lower side of the baffle to the oil baffle plate, and use the oil baffle plate to block the flow of the upper oil until the oil submerges the oil baffle plate and is discharged through the oil drain pipe, so that the oil can float up smoothly.
[0019] 5. When the oil and water level contacts the float, the oil and water act on the float, causing the float to act upward on the first swing rod, causing the first swing rod to drive the knob of the water valve to rotate until the water valve is closed, thereby facilitating automatic control of the oil and water level in the water tank.
