Description

Technical Field

[0001] The utility model relates to the technical field of wastewater treatment, in particular to a wastewater oil-water separation device. Background Art

[0002] Wastewater refers to the general term for the water discharged during the activities of residents and the runoff rainwater. Waste oil will be contained in the wastewater. Therefore, during the process of recycling wastewater, it is necessary to separate the oil and water in the wastewater.

[0003] With the rapid development of the economy and the gradual increase in the degree of industrialization, a large amount of liquid mixed with oil and water will be generated in industrial production. These mixtures cannot be directly discharged and need to be treated. Separating the oil and water is one of the steps. When the existing devices separate the oil and water, the upper-layer oil is sucked out through a floating ball and a liquid suction head. However, the floating ball will float around in the device and is easy to collide with the inner wall of the device, resulting in shaking and poor oil drainage effect. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the deficiencies existing in the prior art, and a wastewater oil-water separation device is proposed.

A plurality of limiting rings are fixedly connected to the circumferential outer wall of the pipe head, and the limiting rings are rotationally connected with the limiting grooves. A sliding rod is threadedly connected to the circumferential outer wall of the threaded sleeve. Two support rods are fixedly connected to the upper surface of the sliding rod. Floating balls are fixedly connected to the tops of the two support rods. Two guide rods are fixedly connected to the inside of the box body. Both of the two guide rods pass through the sliding rod, enabling the sliding rod to move vertically along the guide rods. A conical head is fixedly connected to the top of the pipe head.

[0007] As a further scheme of the utility model, a box cover is hinged to the top of the box body. A liquid inlet pipe communicating with the inside of the box body is fixedly connected to one side of the box body.

Detailed Embodiments

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. The described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0022] Referring to Figures 1 - 3 , a wastewater oil-water separation device includes a box body 1. A fuel pump 3 is fixed to the outer wall of the box body 1 by bolts. A connecting pipe 12 is fixed to the fuel pump 3 by bolts. One end of the connecting pipe 12 extends into the box body 1 and is bonded with a hose 8. One end of the hose 8 is bonded with a pipe head 15. A threaded sleeve 17 is sleeved on the circumferential outer wall of the pipe head 15. A plurality of limiting grooves 19 are formed in the circumferential inner wall of the threaded sleeve 17. A plurality of limiting rings 18 are welded on the circumferential outer wall of the pipe head 15, and the limiting rings 18 are rotatably connected with the limiting grooves 19.

[0023] The threaded sleeve 17 is threadedly connected with a sliding rod 11. Two support rods 13 are welded on the upper surface of the sliding rod 11. Floating balls 14 are bonded to the tops of the two support rods 13. Two guide rods 6 are fixed to the inside of the box body 1 by bolts. Both of the two guide rods 6 pass through the sliding rod 11, enabling the sliding rod 11 to move vertically along the guide rods 6. The top of the pipe head 15 is fixed with a tapered head 16 by bolts. The tapered head 16 is higher than the support rods 13. A box cover 2 is hinged to the top of the box body 1. Wastewater is added into the box body 1, and the wastewater accumulates in the box body 1. The floating balls 14 will move upward following the liquid level of the wastewater under the action of the buoyancy of the wastewater. The floating balls 14 will drive the sliding rod 11 to move vertically upward along the guide rods 6 through the support rods 13. Since the tapered head 16 is higher than the support rods 13 at this time, the wastewater will not enter the tapered head 16. After the wastewater injection is completed, the wastewater is left standing for a period of time. Since the density of oil is less than that of water, the oil will be located above the water. At this time, the box cover 2 is opened, the threaded sleeve 17 is rotated to make the tapered head 16 located in the oil, and then the oil is pumped out through the fuel pump 3. At the same time, it can prevent the floating balls 14 from floating randomly inside and colliding with the inner wall of the device, improving the oil drainage effect of the separation device.

[0024] In this utility model, a liquid inlet pipe 5 communicating with the inside of the box body 1 is welded on one side of the box body 1. Wastewater is added into the box body 1 through the liquid inlet pipe 5. A baffle 7 is fixed to the inner wall on one side of the box body 1 by bolts, and the baffle 7 is located at one end of the liquid inlet pipe 5. There is a gap between the baffle 7 and the box body 1. The baffle 7 will resist the wastewater entering the box body 1 from the liquid inlet pipe 5, thereby reducing the impact force of the wastewater entering. A water outlet pipe 9 communicating with the inside of the box body 1 is welded on the outer wall at the bottom on one side of the box body 1. A valve is arranged on the outside of the water outlet pipe 9. The water outlet pipe 9 is used to discharge the wastewater after separating the oil. A filter box 10 is fixed to the water outlet pipe 9 by bolts. The filter box 10 can filter the wastewater. An exhaust pipe 4 communicating with the inside of the box body 1 is welded on the upper surface of the box body 1. When the wastewater enters the box body 1, it will squeeze the gas in the box body 1 out through the exhaust pipe 4.

[0025] Working principle: When in use, wastewater is added into the box body 1 through the liquid inlet pipe 5. At this time, the baffle 7 will resist the wastewater entering the box body 1 from the liquid inlet pipe 5, thereby reducing the impact force of the wastewater entering. When the wastewater enters the box body 1, the wastewater accumulates in the box body 1 at this time. The floating ball 14 will move upward along with the liquid level of the wastewater under the action of the buoyancy of the wastewater. The floating ball 14 will drive the sliding rod 11 to move vertically upward along the guide rod 6 through the support rod 13. Since the conical head 16 is higher than the support rod 13 at this time, the wastewater will not enter the conical head 16. After the wastewater injection is completed, the wastewater is left standing for a period of time. Since the density of the oil is less than that of the water, the oil will be located above the water. At this time, the box cover 2 is opened and the threaded sleeve 17 is rotated. At this time, the threaded engagement between the threaded sleeve 17 and the sliding rod 11 will move downward. At the same time, the threaded sleeve 17 will drive the pipe head 15 to move downward through the limiting ring 18 and the limiting groove 19, so that the conical head 16 is located in the oil. Then the oil can be pumped out through the oil pump 3. After the oil is pumped out, the liquid level drops. At this time, the floating ball 14 will move along with the water level, so that the conical head 16 is always in the oil to pump out the oil. At the same time, it can prevent the floating ball 14 from floating randomly inside and colliding with the inner wall of the device, improving the oil drainage effect of the separation device.

[0026] In addition, the terms "installation", "setting", "connection", and "socket connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral structure; it can be a mechanical connection or an electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, or there is internal communication between two devices, components or parts. Those of ordinary skill in the art can understand the specific meanings of the above terms in this application according to specific situations.
