Description

Technical Field

[0001] This utility model relates to the field of reflux tank technology, and in particular to a reflux tank that facilitates the cleaning of the internal foam trap mesh. Background Technology

[0002] A reflux tank is a container used in distillation operations to receive the liquid that has been condensed from the vapor rising from the top of the distillation column. It is typically a horizontal tank and consists of a reflux liquid inlet, a foam eliminator, a vapor outlet, an overflow plate, an anti-vortex plate, a reflux liquid outlet, a water separator, and a wastewater discharge outlet.

[0003] The condensate screen in the return tank mainly serves to filter and eliminate foam. After prolonged use, it can become clogged, usually requiring backwashing or replacement. These maintenance tasks all require disassembling the return tank. Therefore, a simple and efficient cleaning method is needed to effectively clean the condensate screen, reducing operational difficulty and maintenance time. Utility Model Content

[0004] This invention addresses the shortcomings of existing technologies by providing a reflux tank that facilitates the cleaning of the internal foam trap.

[0005] This utility model is achieved through the following technical solution:

[0006] A reflux tank for easy cleaning of the internal foam trap includes a tank body, a water distribution manifold, a drain pipe, a reflux liquid outlet, a foam trap assembly, and an inlet assembly. The water distribution manifold is fixedly installed at the bottom of the tank body, the drain pipe is fixedly installed at the bottom of the water distribution manifold, the reflux liquid outlet is fixedly installed at the bottom of one end of the tank body, the foam trap assembly is installed inside the tank body, and the inlet assembly is installed at the top of one end of the tank body. The inlet assembly includes a motor frame, a reflux liquid inlet pipe, a motor, a first gear, a movable pipe, a second gear, a cleaning inlet pipe, a spray nozzle, and an electric control valve. The motor frame and the reflux liquid inlet pipe are fixedly installed at the top of the tank body, the motor is mounted on the top of the motor frame, the first gear is fixedly installed at the motor output end, the movable pipe is movably connected to the outer side of the bottom of the reflux liquid inlet pipe, the second gear is fixedly connected to the outer side of the top of the movable pipe, the cleaning inlet pipe is fixedly installed on the outer side of the reflux liquid inlet pipe, the spray nozzle is fixedly installed on the outer side of the movable pipe, and the electric control valve is installed at the liquid outlet end of the bottom of the movable pipe.

[0007] In a preferred embodiment of this utility model, the mist-catching mesh assembly includes an installation ring, a control lever, a mounting frame, a mist-catching mesh, and a sealing gasket. The installation ring is fixedly disposed inside the tank body, the control lever is vertically and movably connected to the installation ring, the mounting frame is fixedly disposed outside the control lever, the mist-catching mesh is fixedly disposed inside the mounting frame, and the sealing gasket is fixedly disposed outside the mounting frame.

[0008] The foam trap assembly mainly involves installing the foam trap and, when cleaning is required, controlling the operating lever to flip the mounting bracket of the foam trap, thereby flushing away the impurities blocked inside through reverse rinsing, achieving a rapid rinsing effect.

[0009] In a preferred embodiment of this utility model, the top of the control lever is provided with an operating handle, the sealing gasket is made of rubber, and the outer side of the sealing gasket is in close contact with the inner wall of the mounting ring.

[0010] The sealing gasket mainly prevents the reflux liquid from entering the reflux liquid outlet directly without being filtered and defoamed, and also provides a sealing and shielding effect on the edges of the mounting bracket.

[0011] In a preferred embodiment of the present invention, the motor output end passes through the motor frame and extends to the inner side of the top of the tank, and the first gear at its output end meshes with the second gear.

[0012] The main function of the motor is to drive the first gear, which in turn drives the second gear meshing with it to rotate, thereby directing the spray nozzle toward the foam-catching mesh. During the spray cleaning process, the motor rotates and causes the spray nozzle to swing left and right to change the cleaning position.

[0013] In a preferred embodiment of this utility model, the movable tube is located on the outside of one side of the mounting bracket, and the rotation of the movable tube does not interfere with the mounting bracket.

[0014] The beneficial effects of this utility model are:

[0015] During routine maintenance, the reflux tank, which facilitates the cleaning of the internal foam trap, allows the mounting bracket for the foam trap to be flipped by rotating the control lever. Subsequently, the motor controls the gears to rotate, changing the position of the movable tube and sealing the bottom of the movable tube. This allows high-pressure water to be sprayed from the nozzles, and the oscillating nozzles achieve a large-area continuous backflow rinse of the foam trap, achieving an ideal cleaning effect. This avoids the problem of needing to disassemble and clean the screen during routine maintenance, which consumes a lot of time. Attached Figure Description

[0022] like Figure 1-4 The reflux tank shown is designed for easy cleaning of the internal foam trap. It includes a tank body 1, a water separator 2, a drain pipe 3, a reflux outlet 4, a foam trap assembly 5, and an inlet assembly 6. The water separator 2 is fixedly installed at the bottom of the tank body 1, the drain pipe 3 is fixedly installed at the bottom of the water separator 2, the reflux outlet 4 is fixedly installed at the bottom of one end of the tank body 1, the foam trap assembly 5 is installed inside the tank body 1, and the inlet assembly 6 is installed at the top of one end of the tank body 1. The inlet assembly 6 includes a motor frame 61, a reflux inlet pipe 62, a motor 63, a first gear 64, a movable pipe 65, and a second gear 66. 6. The cleaning inlet pipe 67, the spray nozzle 68, and the electric control valve 69, the motor frame 61, and the return liquid inlet pipe 62 are fixedly installed on the top of the tank body 1. The motor 63 is installed on the top of the motor frame 61. The first gear 64 is fixedly installed on the output end of the motor 63. The movable pipe 65 is movably connected to the bottom outer side of the return liquid inlet pipe 62. The second gear 66 is fixedly connected to the top outer side of the movable pipe 65. The cleaning inlet pipe 67 is fixedly installed on the outside of the return liquid inlet pipe 62. The spray nozzle 68 is fixedly installed on the outside of the movable pipe 65. The electric control valve 69 is installed at the bottom outlet end of the movable pipe 65.

[0023] Specifically, the mist trap assembly 5 includes a mounting ring 51, a control lever 52, a mounting frame 53, a mist trap 54, and a sealing gasket 55. The mounting ring 51 is fixedly installed inside the tank body 1. The control lever 52 is vertically and movably connected to the mounting ring 51. The mounting frame 53 is fixedly installed outside the control lever 52. The mist trap 54 is fixedly installed inside the mounting frame 53. The sealing gasket 55 is fixedly installed outside the mounting frame 53. An operating handle is provided at the top of the control lever 52. The sealing gasket 55 is made of rubber and is in close contact with the inner wall of the mounting ring 51. The output end of the motor 63 passes through the motor frame 61 and extends to the top inner side of the tank body 1. The first gear 64 and the second gear 66 at its output end mesh. The movable tube 65 is located outside one side of the mounting frame 53. The rotation of the movable tube 65 does not interfere with the mounting frame 53.

[0024] In this embodiment, a return pipe is connected to the top of the return liquid inlet pipe 62 at the top of the return tank body 1. After the liquid enters from the return liquid inlet pipe 62, it enters the interior of the tank body 1 through the movable pipe 65. After being filtered and defoamed by the foam eliminator 54, it is discharged from the return liquid outlet 4. The sealing gasket 55 on the outside of the foam eliminator 54 mounting bracket 53 is in close contact with the inner wall of the mounting ring 51 to ensure that all return liquid is effectively filtered. The impurities remaining in the liquid will settle in the water separator 2 and be discharged from the drain pipe 3. After long-term use, the foam eliminator 54 will become clogged and needs to be cleaned regularly. At this time, the operating handle at the top of the control operating lever 52 is rotated to flip the mounting bracket 53 fixed on the surface of the control operating lever 52 and fix it in the mounting ring 51, so that the foam eliminator 54 is reversed.

[0025] Furthermore, the motor 63 starts, causing the first gear 64 installed at its output end to drive the second gear 66 at the top of the movable tube 65 to rotate, making the movable tube 65 rotate 180°. Then, the liquid inlet end at the top of the return liquid inlet pipe 62 is closed, and high-pressure water flow is connected to the liquid inlet end of the cleaning liquid inlet pipe 67 on its outside. The electric control valve 69 at the tail end of the movable tube 65 is closed, so that the high-pressure water flow can only be sprayed from the spray nozzle 68. The high-pressure water flow will directly act on the back of the foam trap 54. The movable tube 65 swings due to the small forward and reverse rotation of the motor 63. After the high-pressure water flow is sprayed from the spray nozzle 68, it acts on the back of the foam trap 54 in a large fan shape, thereby effectively cleaning the impurities adhering to its surface. The cleaned wastewater will be discharged from the drain pipe 3. After cleaning, the movable tube 65 is reset, and the electric control valve 69 is opened. The operating handle is rotated to rotate the control operating lever 52, which drives the mounting bracket 53 to flip and reset again, completing the cleaning work.
