Description

Technical Field

[0001] This utility model relates to the field of waste oil recovery technology, and in particular to a waste oil recovery device for oily wastewater ponds. Background Technology

[0002] A wastewater pond is a facility used to collect, store, and initially treat wastewater. It can temporarily accommodate wastewater from various sources, such as domestic sewage or the sewage portion of rainwater runoff. Its main function is to act as a buffer to prevent the disorderly discharge of wastewater, while also providing a certain amount of water quantity and quality adjustment for subsequent wastewater treatment steps. Since the wastewater in the wastewater pond often contains oil, when oily wastewater is discharged into water bodies, the oil will form an oil film on the water surface. This oil film will hinder oxygen from entering the water body, resulting in a decrease in the dissolved oxygen content in the water body. Direct discharge will affect the respiration of aquatic organisms. Therefore, it is necessary to recover and collect the sludge and oil from the wastewater pond.

[0003] Oil and water mixtures in oily wastewater tanks will naturally separate into layers due to the different densities of oil and water (oil is less dense than water), with the oil layer on top and the water layer at the bottom. Generally, the upper oil layer is absorbed by a device. However, in low-temperature environments, the upper oil layer will solidify and float on the water surface, making it difficult to absorb directly through pipes and potentially clogging the pipes.

[0004] Therefore, it is necessary to improve the existing technology to solve the above-mentioned technical problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides an oil recovery device for oily wastewater ponds, solving the problems mentioned in the background section.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an oil recovery device for oily wastewater ponds, comprising a plastic float, an annular oil suction pipe fixedly installed on the upper side wall of the plastic float, oil suction heads fixedly connected in a circumferential arrangement on the side wall of the annular oil suction pipe, connecting pipes fixedly installed in a circumferential arrangement inside the plastic float, the lower end of the outer wall of the connecting pipe connected to the oil suction head, an arc-shaped pipe fixedly installed on the upper end of the outer wall of all the connecting pipes, a connector head fixedly installed in the middle of the upper part of the outer wall of the plastic float, a negative pressure pipe fixedly installed on the upper end of the outer wall of the connector head, and a side wall of the connector head fixedly connected to the arc-shaped pipe.

[0007] As a further technical solution of this utility model, connecting rods are fixedly installed in a circumferential arrangement at the lower end of the side wall of the plastic float, and all the connecting rods are simultaneously fixedly connected to heating tubes, with heating resistance wires fixedly installed inside the heating tubes.

[0008] As a further technical solution of this utility model, the lower end of the outer wall of the heating tube is located below the lower end of the outer wall of the plastic float plate, and the diameter of the heating tube is larger than the diameter of the annular oil suction tube.

[0009] As a further technical solution of this utility model, a filter cover is inserted into the oil suction head input end, and a filter screen is fixedly installed on the filter cover.

[0010] As a further technical solution of this utility model, a sliding rod is fixedly installed on the negative pressure pipe, a sliding sleeve is slidably connected to the side wall of the sliding rod, a rotating rod is fixedly installed on the side wall of the sliding sleeve, a motor is provided at the end of the rotating rod away from the sliding sleeve, the output end of the motor is fixedly connected to the rotating rod, and an mounting plate is fixedly installed at the lower end of the outer wall of the motor.

[0011] As a further technical solution of this utility model, a second connector is fixedly installed on the upper end of the outer wall of the negative pressure pipe, and the second connector is a rotary joint, with the axis of the second connector coinciding with the axis of the motor.

[0012] This invention provides a waste oil recovery device for oily wastewater ponds, which has the following advantages compared with the prior art:

[0013] 1. In use, the device floats on the surface of the sewage in the sewage tank via a plastic float plate. The negative pressure pipe is used to connect with external negative pressure collection equipment, creating negative pressure in the arc-shaped pipe, connecting pipe, and oil suction head. The oil suction head then absorbs and collects the oil floating on the surface of the sewage. Furthermore, the heating resistance wire can be activated to heat the heating tube, which heats the oil layer on the surface of the sewage in the sewage tank, causing it to melt from a solid to a liquid state, making it easier for the oil suction head to absorb. This allows the device to be used in low-temperature environments, thereby improving its practicality.

[0014] 2. When in use, the rotation of the motor drives the negative pressure pipe to rotate back and forth around the axis of the motor and the second connector, thereby causing the plastic float to rotate back and forth around the axis of the motor and the second connector. This allows the device to more comprehensively absorb the surface of the sewage in the sewage tank, further improving the recycling effect of the device. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-5This utility model provides a technical solution for an oil recovery device for oily wastewater ponds: It includes a plastic float 100, an annular oil suction pipe 200 fixedly installed on the upper side wall of the plastic float 100, oil suction heads 210 fixedly connected to the side wall of the annular oil suction pipe 200 in a circumferential arrangement, connecting pipes 220 fixedly installed in a circumferential arrangement inside the plastic float 100, the lower end of the outer wall of the connecting pipes 220 connected to the oil suction heads 210, and arc-shaped pipes 300 fixedly installed on the upper end of the outer wall of all connecting pipes 220. A connector 310 is fixedly installed at the middle of the upper part of the outer wall. A negative pressure pipe 400 is fixedly installed at the upper part of the outer wall of the connector 310. The side wall of the connector 310 is fixedly connected to the arc-shaped pipe 300. The device floats on the surface of the sewage in the sewage tank 1 through the plastic float plate 100. The negative pressure pipe 400 is used to connect with the external negative pressure collection equipment to generate negative pressure in the arc-shaped pipe 300, and generate negative pressure in the connecting pipe 220 and the oil suction head 210, so that the oil sludge floating on the surface of the sewage can be absorbed and collected through the oil suction head 210. Connecting rods 500 are fixedly installed circumferentially on the lower side wall of the plastic float 100. All connecting rods 500 are simultaneously fixedly connected to heating tubes 510. Heating resistance wires 520 are fixedly installed inside the heating tubes 510. By activating the heating resistance wires 520, the heating tubes 510 are heated, thereby heating the oily layer on the surface of the sewage in the sewage tank 1, causing it to melt from a solid state into a liquid state, making it easier for the oil suction head 210 to absorb. The lower end of the outer wall of the heating tubes 510 is located below the lower end of the outer wall of the plastic float 100. The diameter of the heating tubes 510 is larger than the diameter of the annular oil suction pipe 200, allowing the heating tubes 510 to have a larger heating range.

[0023] like Figure 5 As shown, a filter cover 211 is inserted into the input end of the oil suction head 210, and a filter screen 212 is fixedly installed on the filter cover 211 to prevent some impurities on the surface of the sewage from being absorbed by the oil suction head 210.

[0024] like Figure 1-4As shown, a sliding rod 600 is fixedly installed on the negative pressure pipe 400. A sliding sleeve 610 is slidably connected to the side wall of the sliding rod 600. A rotating rod 620 is fixedly installed on the side wall of the sliding sleeve 610. A motor 630 is provided at the end of the rotating rod 620 away from the sliding sleeve 610. The output end of the motor 630 is fixedly connected to the rotating rod 620. An installation plate 640 is fixedly installed at the lower end of the outer wall of the motor 630. The installation plate 640 is fixedly connected to the inner side wall of the sewage tank 1. By sliding the sliding rod 600 and the sliding sleeve 610, the plastic float 100 can move up and down along the height of the sewage surface, and the oil suction head 210 can move up and down with the change of the sewage surface height. A connector 410 is fixedly installed on the upper end of the outer wall of the negative pressure pipe 400. The connector 410 is a swivel joint, and the axis of the connector 410 coincides with the axis of the motor 630. The connector 410 can facilitate the connection between the negative pressure pipe 400 and the external negative pressure collection equipment. By rotating the motor 630, the negative pressure pipe 400 can be driven to rotate back and forth around the axis of the motor 630 and the connector 410, thereby allowing the plastic float 100 to rotate back and forth around the axis of the motor 630 and the connector 410, so that the device can more comprehensively absorb the oil stains on the surface of the sewage in the sewage tank 1.

[0025] The working principle of this utility model is as follows: In use, the mounting plate 640 is first fixedly connected to the inner wall of the sewage tank 1. The device floats on the surface of the sewage in the sewage tank 1 via a plastic float plate 100. The negative pressure pipe 400 is used to connect to an external negative pressure collection device, generating negative pressure in the arc-shaped pipe 300, which in turn generates negative pressure in the connecting pipe 220 and the oil suction head 210. This allows the oil suction head 210 to absorb and collect the oil floating on the surface of the sewage. Furthermore, the heating resistance wire 520 is activated to heat the heating tube 510, which in turn heats the oil layer on the surface of the sewage in the sewage tank 1, causing it to dissolve from its solid state. The oil is melted into a liquid state, making it easier for the oil suction head 210 to absorb it. At the same time, the sliding rod 600 and the sliding sleeve 610 allow the plastic float 100 to move up and down along the height of the sewage surface, and the oil suction head 210 can move up and down with the change of the sewage surface height. Then, the rotation of the motor 630 can drive the negative pressure pipe 400 to rotate back and forth around the axis of the motor 630 and the second connector 410, so that the plastic float 100 can rotate back and forth around the axis of the motor 630 and the second connector 410, so that the device can more comprehensively absorb the oil on the surface of the sewage in the sewage tank 1.

[0026] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model are implemented according to conventional methods in the art, unless otherwise specified or limited.
