Description

Technical Field

[0001] The utility model relates to the field of water treatment, in particular to an adjustable fully sealed water outlet device. Background Art

[0002] Flotation systems are water treatment equipment that use a dissolved air system to generate a large number of fine bubbles in water. These bubbles, in the form of highly dispersed air, attach to suspended particles, causing them to float to the water surface due to buoyancy, thereby achieving solid-liquid separation. However, during the flow of water in existing flotation systems, some of the bubbles attached to the suspended particles rupture and dissolve in the water, causing the suspended particles to remain in the water and reducing the flotation system's solid-liquid separation effectiveness. The material discharged from the flotation system's outlet is treated clean water, which is then discharged through the outlet to achieve the purpose of water purification.

[0003] However, the existing water outlet device has certain defects in actual use. The water discharged after being treated by the flotation machine still contains certain suspended matter and other impurities, which cannot be filtered. Over time, it is easy to cause internal impurities to accumulate, thereby affecting the drainage effect. It is also easy to cause blockage, which is inconvenient to clean. Utility Model Content

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] See also Figure 1-Figure 5According to an embodiment of the present invention, an adjustable fully sealed water outlet device includes a water outlet pipe 2, which is fixedly connected to the side wall of the flotation machine body 1, and can be convenient for the flotation machine to discharge water after solid-liquid separation after pre-treatment such as industrial wastewater treatment and municipal sewage treatment. The flotation machine body 1 is a relatively mature technology and is not described in detail here. The figure only shows a part of it, and the ends of the water outlet pipe 2 are respectively connected to the first pipe 5 and the second pipe 6. Two pipes can be used for discharge, and a spare is used, which is convenient for emergency and replacement operations, and can be easily adjusted and disassembled. The ends of the first pipe 5 and the second pipe 6 are commonly connected to the discharge pipe 3 , convenient for discharge operation, an adjustment component is provided inside the water outlet pipe 2, which can facilitate the adjustment and switching operation. At the same time, when one of them is in use, ensure that the other is in a sealed state. The adjustment component includes a baffle ring 22 and a rubber ring 13 symmetrically arranged inside the water outlet pipe 2, both of which are two groups. The two rubber rings 13 are located outside the two ends of the baffle ring 22, and a sealing plate 23 is provided outside the two baffle rings 22. The diameter of the sealing plate 23 is smaller than the inner diameter of the hollow of the rubber ring 13 and the baffle ring 22, which can block the sealing plate 23. The two sealing plates 23 can be fixed by welding through the connecting rod 21, which can facilitate subsequent movement and adjustment.

[0026] See also Figure 1-Figure 5 In order to filter the treated water and prevent suspended matter, colloids, etc. from being discharged together, a mounting assembly card 11 is welded to the inner side wall of the flotation machine body 1, and a filter plate 4 with an L-shaped cross-section is provided inside the flotation machine body 1. The filter plate 4 is provided with a card slot 10 adapted to the card plate 11. In order to limit it, a limiting member 12 (the material can be a flexible material such as rubber) is bonded to the end of the card plate 11. The first pipeline 5 and the second pipeline 6 are both equipped with a treatment box 7 of the treatment assembly, and the first filter screen 14 and the second filter screen 15 are installed in sequence inside the treatment box (a group of filter screens can also be installed according to the situation, and the assembly is arranged according to the actual situation), so that the treated water can be filtered again.

[0027] See also Figure 1-Figure 5In order to facilitate the regular disassembly, cleaning and replacement of the treatment box 7 without affecting the normal operation of the equipment and ensuring the sealing during use, the two ends of the treatment box 7 are connected with a connecting pipe 20 of a connecting mechanism, and the end of the connecting pipe 20 and the first pipeline 5 close to each other are welded with a connecting flange 8 (fixed by screws), and a gasket 9 is provided between the two connecting flanges 8 to ensure the firmness and sealing of the connection, and a plug-in ring 16 is welded on the end of the connecting flange 8 on the connecting pipe 20, and a plug-in ring 16 is provided inside the connecting flange 8 on the first pipeline 5. 6 is adapted to the plug-in groove 18, which assists in the plug-in connection. The plug-in ring 16 is equidistantly bonded to the side surface with a sealing ring 17, and the inner wall of the plug-in groove 18 is provided with a sealing groove 19 that is interference fit with the sealing ring 17 to ensure the sealing during connection. The structure of the connecting mechanism on the second pipeline 6 is the same as that on the first pipeline 5. One is used and the other is spare. In order to facilitate the installation operation, the first pipeline 5 and the second pipeline 6 are both connected with a telescopic tube (which can be a corrugated tube for easy installation and disassembly operations, or other materials, which is a relatively mature technology and will not be described here).

[0028] In order to facilitate understanding of the above technical solutions of the present invention, the working principle or operation method of the present invention in actual process is described in detail below.

[0029] The filter plate 4 can be positioned and assembled by the cooperation of the card plate 11 and the card slot 10, and the limiter 12 can limit it. After the sewage is treated by the flotation machine body 1, the water is filtered by the filter plate 4 and discharged through the outlet pipe 2. At this time, the inner part of the outlet pipe 2 is as follows: Figure 3 As shown, water enters the treatment box 7 through the second pipe 6, is filtered through the first filter 14 and the second filter 15, and suspended solids can be filtered again, and then discharged through the discharge pipe 3 for the next treatment operation. As the impurities on the filter screen inside the treatment box 7 are gradually accumulated, blockage occurs. At this time, as the water enters the outlet pipe 2, due to the blockage of the filter screen on the second pipe 6, a thrust is generated on the sealing plate 23 at the end of the first pipe 5, which can move the sealing plate 23 toward one end of the first pipe 5, and pass through the rubber ring 13. The sealing plate 23 of the second pipe 6 section is under the action of the connecting rod 21. It moves downward, passes through the rubber ring 13 and moves to the stop ring 22 to limit the position, thereby sealing the second pipeline 6, and the first pipeline 5 is connected, and the filtering operation is performed through the treatment box 7 thereon. At this time, the treatment box 7 on the second pipeline 6 can be disassembled, and the fixation of the connecting flange 8 can be lost by unscrewing the screws. With the help of the telescopic tube, the plug-in ring 16 can be taken out from the plug-in groove 18, and then the treatment box 7 can be removed for cleaning or replacement. After assembly, when the filter screen in the treatment box 7 on the first pipeline 5 is clogged, the principle is the same as above, and the water can be drained through the second pipeline 6, and the first pipeline 5 is blocked and can be disassembled.

[0030] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
