Description

Technical Field

[0001] This utility model relates to the field of oily wastewater treatment technology, specifically to an air flotation device for treating oily wastewater. Background Technology

[0002] Air flotation devices used for treating oily wastewater are key equipment for wastewater treatment in industries such as petrochemicals, machinery processing, and catering. Their core principle is to achieve solid-liquid separation through the adhesion of microbubbles with oil droplets and suspended solids.

[0003] The prior art discloses an air flotation device for treating oily wastewater, with announcement number CN212687629U. The device includes an air supply pipe, an air valve, and an air jet pipe. The air jet pipe includes a pipe body and a sealing body. The pipe body is an integrally formed hollow structure with one open end and the other closed end. Uniformly distributed air jet holes are provided on the pipe body. The sealing body includes a connecting part and a nozzle. The nozzle is used to inject chemicals into the pipe body. The air valve seals the connection between the air outlet and the connector on the pipe body. The air valve is used to adjust the amount of gas entering the pipe body. There is at least one air outlet, and the number of air jet pipes and air valves are the same as the number of air outlets. This allows for control of the dissolved air in the oily wastewater. Simultaneously, chemicals can be injected to treat the oily wastewater. Air jetting and solvent addition can be carried out simultaneously or separately to achieve staged treatment, improving treatment efficiency and versatility.

[0004] The aforementioned air valve used to seal the connection between the gas supply pipe and the jet pipe, and the gas supply pipe is equipped with a support device, will cause the gas supply pipe to shake when spraying agents and dissolving gas, which can easily cause damage or breakage to the gas supply pipe, thus rendering the gas supply pipe unusable.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1-5 The present invention provides the following technical solution:

[0028] An air flotation device for treating oily wastewater includes a support device 1 and a connecting air pipe 4. An air jet pipe 2 is fixedly connected to the surface of the connecting air pipe 4, and an air jet nozzle 3 is fixedly connected to the surface of the air jet pipe 2. The connecting air pipe 4 is threaded to the top surface of the support device 1.

[0029] The support device 1 includes a slide rail 11, a support air pipe 12, a clamping assembly 13, and a connecting base 14. The connecting base 14 is fixedly connected to the bottom surface of the support air pipe 12, the slide rail 11 is fixedly connected to the surface of the support air pipe 12, and the support air pipe 12 is threadedly connected to the bottom surface of the connecting air pipe 4. The connecting air pipe 4 can be disassembled and replaced. Different specifications of connecting air pipe 4, jet nozzle 3, and jet pipe 2 can be used. It is suitable for oil-water separation of oily wastewater at different depths. The connecting base 14 is installed at the bottom of the clamping assembly 13.

[0030] The clamping assembly 13 includes a limiting unit and a sliding unit, which are arranged sequentially from bottom to top.

[0031] The limiting unit includes a metal frame 131, which is threaded to the four corners of the connecting base 2 14. The bottom of the connecting base 2 14 is provided with an air pipe connector, which can be connected to an external air pipe, so that dissolved gas can be input into the connecting base 2 14 and the supporting air pipe 12 through the air pipe connector. The outward end of the metal frame 131 is threaded to a connecting base 1 133, and the top of the connecting base 1 133 is rotatably connected to a support arm 132. There are four support arms 132, which are distributed around the supporting air pipe 12. The four support arms 132 can clamp and fix the supporting air pipe 12, which can protect the stability of the supporting air pipe 12 and increase the service life of the supporting air pipe 12.

[0032] The sliding unit includes a connecting slider 134, a connecting frame 135 fixedly connected to the outer surface of the connecting slider 134, and a connector 136 mounted on the inner wall surface of the connecting frame 135. The connector 136 is connected to the top of the support arm 132 via a pin. The connector 136 and the support arm 132 are connected by a pin, allowing for the disassembly and replacement of support arms 132 of different specifications, and extending the service life of the support arm 132. The connector 136 is movably connected to the outer surface of the connecting slider 134 and slidably connected to the surface of the slide rail 11. The connecting slider 134 can connect support arms 132 of different specifications. The two outward ends of the connecting slider 134 are threaded with limit blocks 137. The connecting slider 134 is slidably connected to the inner wall surface of the slide rail 11, and the limit blocks 137 are slidably connected to the inner wall surface of the slide rail 11. The connecting slider 134 and the limit blocks 137 slide on the inner wall surface of the slide rail 11, and the positions of the connecting slider 134 and the limit blocks 137 can be adjusted. At the same time, the limit blocks 137 and the connecting slider 134 are connected by bolts, which makes it easy to disassemble and replace the connecting slider 134 and the limit blocks 137.

[0033] When in use, rotating the bolt disengages the connecting slider 134 and the limiting block 137, loosening the connection between the limiting block 137 and the connecting slider 134. Pulling the limiting block 137 outwards further disengages it from the connecting slider 134, loosening the connection between the connecting slider 134 and the slide rail 11.

[0034] Then pull the connecting slider 134 outward to disengage it from the slide rail 11. Then pull the connecting slider 134 upward to drive the support arm 132 upward.

[0035] Pulling out the pin allows it to disengage from the connecting slider 134, connecting base 133, and support arm 132, enabling the support arm 132 to be disassembled and replaced. Different specifications of support arms 132 can be used, facilitating the maintenance and cleaning of the support arm 132.

[0036] A pin is inserted between the replaced support arm 132, connecting base 133 and connector 136 to connect the support arm 132, connecting base 133 and connector 136, and to determine the position of the support arm 132.

[0037] This involves inserting the connecting slider 134 into the slide rail 11, and then rotating the bolt. The bolt can thread-fix the connecting slider 134 and the limiting block 137, thereby determining the position of the support arm 132.

[0038] An external air pipe is connected to the air pipe connector at the bottom of the connecting base 2 14, which allows dissolved gas in the external air pipe to be input into the interior of the supporting air pipe 12. The dissolved gas enters the interior of the connecting air pipe 4 through the supporting air pipe 12, and then passes through the jet pipe 2 and is sprayed through the jet nozzle 3, so that the dissolved gas enters the oily wastewater.

[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to the embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
