Description

Technical Field

[0001] The utility model belongs to the technical field of drainage equipment, in particular to an adjustable anti-splashing device for a drainage device. Background Art

[0002] A large amount of waste gas containing acidic gases such as fluoride and sulfur dioxide will be discharged during the production process of electrolytic aluminum, which is harmful to the environment and human health. Therefore, it is necessary to treat these waste gases, and flue gas desulfurization is such a treatment process. The slurry (solid content of 10% to 30%, pH value of 4.0-6.0) of the absorption tower of the electrolytic aluminum desulfurization system is transported to the slurry cyclone by the absorption tower slurry discharge pump for solid-liquid separation and concentration. The concentrated slurry (solid content of 40%-50%, mainly gypsum) bottom flow liquid enters the vacuum belt dehydrator through the vacuum belt dehydrator feed box for dehydration. After the vacuum belt dehydration passes through the gas-liquid separator, the wastewater is discharged through the drain port, and the dehydrated gypsum enters the gypsum storage room. The overflow liquid separated by the slurry cyclone directly enters the filtrate pool and returns to the absorption tower through the filtrate pump. The liquid from the filtrate separator enters the wastewater buffer tank and is discharged to the desulfurization wastewater treatment system through the wastewater lift pump.

[0003] When acidic wastewater is discharged through the drain outlet, due to the large water flow rate and fast instantaneous discharge speed, it is very easy to cause water splashing, threatening the personal safety of workers and causing a dirty and messy workshop environment.

DETAILED DESCRIPTION

[0025] In order to make the purpose, technical solutions and advantages of the embodiments of the utility model clearer, the technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments.

[0026] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the present invention to be protected, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] The utility model provides an adjustable anti-splashing device for a drainage device, which is mainly used as a control device in the drainage process of an electrolytic aluminum desulfurization system, and is mainly used to realize the functions of drainage device control and splash prevention. The device has the characteristics of being adjustable, and the opening and closing force of the device valve can be adjusted according to the actual production process control needs to achieve the best drainage device effect.

[0028] like Figures 1 to 6As shown, an adjustable anti-splash device for a drainage device includes a valve body 1. The specific structure of the valve body 1 is similar to that of a valve in the prior art, and will not be described in detail. The valve body 1 is provided with a valve seat 11 for introducing a medium and a drainage channel 12 for discharging the medium. When in use, the valve seat 11 and the drainage port of the drainage device are connected and fixed. A sealing seat 13 is provided on the outer wall of the valve body 1 outside the drainage channel 12. The sealing seat 13 mainly plays a sealing role. A valve cover 5 is slidably provided on the inner wall of the sealing seat 13. Some sealing rings can also be added to enhance the sealing effect, mainly to prevent water leakage between the sealing seat 13 and the valve cover 5. The interior of the valve cover 5 is hollow. When the valve body 1 is draining water, the water flows into the valve seat 11 to reach the inside of the valve body 1, and then is discharged into the inner cavity of the valve cover 5 through the drainage channel 12. The valve cover 5 and the sealing seat 13 are connected and fixed by an elastic connector 6. The valve cover 5 and the sealing seat 13 are not rigidly connected, but elastically connected, and can have a certain elastic and telescopic displacement. When draining water, the rapid impact of the water flow can allow the valve cover 5 to slide relative to the sealing seat 13. This elastic and flexible connection can shorten the length of the valve cover 5 as a whole. At the same time, at the moment of drainage, the displacement of the valve cover 5 increases the effective depth of water flowing through the valve cover 5, thereby enhancing the effect of preventing splashing.

[0029] Furthermore, the inside of the valve cover 5 is provided with multiple layers of installation grooves 54 with different diameters and distributed in a stepped manner, and the inner diameter of the installation grooves 54 decreases from the outside of the valve cover 5 to the valve body 1. The installation grooves 54 of different diameters are respectively provided with detachable weight rings (not shown in the figure). With such a design, the number and weight of the weight rings can be adjusted according to the water flow rate through the weight-adjustable weight rings, thereby increasing the weight of the valve cover 5 as a whole. Moreover, after the weight rings are installed, the inner diameter of the inside of the valve cover 5 also becomes smaller, and the inner diameter becomes the inner diameter of the weight ring instead of the inner diameter of the installation groove 54. By changing the parameters such as the water flow inner diameter of the valve cover 5 and the weight of the valve cover 5, the water flow speed and direction are controlled, thereby avoiding multiple problems such as splashing of water flow and flow deviation.

[0030] Furthermore, a limit ring 51 and a sliding part 52 are sequentially arranged on one side of the valve cover 5. The outer diameter of the limit ring 51 is larger than the outer diameter of the sliding part 52. A drainage hole 53 communicating with the mounting groove 54 is arranged inside the sliding part 52. A sliding hole 14 is arranged on the inner wall of the sealing seat 13. The outer wall of the sliding part 52 slides against the inner wall of the sliding hole 14. When the water is not drained, the limit ring 51 and the sealing seat 13 are closely arranged. At this time, the elastic connection 1 6 is not stretched. When the water is drained, the impact of the water flow causes the valve cover 5 to slide outward, and the elastic connection 1 6 is stretched.

[0031] Furthermore, the inner diameter of the sliding hole 14 is larger than the inner diameter of the drainage channel 12 .

[0032] like Figure 1-4As shown, the valve body 1 is threadedly connected with a rotating shaft 21, and a valve core is arranged at the bottom end of the rotating shaft 21. The valve core is arranged inside the valve body 1 and is used to adjust the flow rate of the medium flowing inside the valve body 1. It should be noted that the valve body 1 of the utility model does not play a role in cutting off the fluid. The opening and closing degree of the valve body 1 is limited. Within the limited opening and closing range, it only plays a role in controlling the flow, that is, the valve body 1 is open as a whole, and the internal medium can flow through. However, rotating the rotating shaft 21 can only adjust the internal valve core to rotate a certain angle, which plays a role in controlling the flow.

[0033] Furthermore, a long strip rotating part 2 is provided at the upper end of the rotating shaft 21, a rack 22 distributed in an arc shape is provided on one side of the rotating part 2, a driving motor 3 is provided on the valve body 1 through a fixing seat 8, a gear 31 is connected to the output end of the driving motor 3, and the gear 31 is meshed and connected with the rack 22. The rack 22 is provided at the lower side of the end of the rotating part 2, and when the gear 31 is meshed with the rack 22, the upper side of the gear 31 is limited by the rotating part 2. This structure can automatically control the rotation of the rotating shaft 21 to achieve flow control of the valve body 1.

[0034] The adjustable anti-splash device of the utility model adjusts the tightness and opening and closing speed of the drainage valve through the adjustable rotating shaft 21, and cooperates with the valve cover 5 and the weight-adjustable counterweight ring on the valve cover 5. The weight of the counterweight ring can be adjusted according to the water flow rate to control the water flow speed and direction. Under the dual effects of the rotating shaft 21 and the valve cover 5 (counterweight ring), the existing drainage device is solved. When it is too tight, it cannot be opened for drainage, and when it is too loose, the water flow is directly discharged and splashed, and the flow direction is offset. The adjustable control device can solve the safety hazards when discharging acidic wastewater, and also improve the working environment of the enterprise's desulfurization workshop.

[0035] Furthermore, the bottom of the driving motor 3 and the valve cover 5 are connected and fixed via an elastic connecting member 7 , so as to further enhance the connection stability of the valve cover 5 .

[0036] In the present invention, the elastic connecting member 1 6 is a spring, and a plurality of the elastic connecting members 1 6 are evenly distributed along the circumference of the valve cover 5. The elastic connecting member 2 7 is a spring, and at least one elastic connecting member 2 7 is provided.

[0037] The working principle of the anti-splash adjustable control valve for the drainage device of the electrolytic aluminum desulfurization system is as follows:

[0038] According to the on-site wastewater concentration and process water control volume, the tension of the rotating shaft 21 is adjusted, and the weight of the counterweight ring is adjusted at the same time, and the two-way adjustment is matched. When there is no water in the gas-liquid separator, the valve cover 5 fits tightly with the sealing seat 13 to form a seal. When the water in the gas-liquid separator reaches the discharge volume, the gas-liquid separator automatically opens to drain. According to the size of the water flow, the rotating shaft 21 rotates to keep the valve body 1 at a suitable opening, thereby achieving control of the flow and flow direction of the valve body 1. During the desulfurization process of electrolytic aluminum, when acidic wastewater is discharged through the device, splashing and injuring people and environmental pollution can be prevented. Since the device has the adjustable characteristics, the opening and closing force can be adjusted according to actual production needs to achieve the best drainage control effect.

[0039] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may be subject to various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
