Description

Technical Field

[0001] This utility model relates to the field of vortex well structure technology, and in particular to a device for preventing siltation in the internal water intake well of a vortex well. Background Technology

[0002] In the production process of steel rolling mills, after the turbid circulating water from the cooling equipment completes its cooling task, it enters the first stage of wastewater treatment—the vortex well—through the drainage pipes in the trench. Wastewater flows into the vortex well from the inlet, and impurities such as iron oxide scale gradually settle at the bottom of the vortex well. Over time, these sediments need to be grabbed and cleaned by using a grab bucket to descend along the inner well to the bottom.

[0003] The initially purified water flows into the suction well as the water level rises. However, even after initial sedimentation in the vortex well, a small amount of iron oxide scale remains in the water, and these impurities settle at the bottom of the suction well. The suction pipe of the suction well is located at the top, drawing out the relatively clean water from the upper layer, but the iron oxide scale at the bottom continues to accumulate. Excessive iron oxide scale not only reduces the water storage capacity of the suction well but also increases the weight of the suction well and the inner well, posing a risk of collapse to the inner well.

[0004] Currently, cleaning the iron oxide scale inside the suction well usually requires personnel to enter the well during shutdown maintenance. The cramped and damp environment not only increases the labor intensity for workers but also exposes them to higher safety risks, severely impacting production efficiency and increasing production costs.

[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. 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.

[0022] The purpose of this invention is to provide a device for preventing sludge deposition in the internal suction well of a vortex well, so as to solve the problems existing in the prior art. It has a simple structure, is easy to use, and effectively avoids sludge deposition in the suction well.

[0023] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0024] This utility model provides a device for preventing sludge sedimentation in the internal suction well of a vortex well, such as... Figure 1As shown, the system includes: an outer well 4, a base 6, a suction well 5, an inner well 3, a drain pipe 2, and a water flow disturbance mechanism. An inlet 1 is located on one side of the bottom of the outer well 4, through which the circulating water from the cooling equipment enters the outer well 4 and undergoes preliminary sedimentation. The base 6 is located at the bottom of the outer well 4, and both the base 6 and the bottom of the outer well 4 have sludge-containing spaces connected to the outer well 4. The suction well 5 is located on the base 6, with its top opening higher than the inlet 1, allowing the pre-sedimented circulating water to enter the suction well 5 from its top opening. One end of the inner well 3 is installed inside the suction well 5 and passes through its bottom, communicating with the sludge-containing space; the other end extends out of the outer well 4, allowing the grab bucket to move along... The inner well 3 descends to the bottom of the outer well 4 and grabs the iron oxide scale at the bottom of the outer well 4; the bottom end of the drain pipe 2 extends into the suction well 5 and is located at the top of the suction well 5, while the other end extends out of the outer well 4 to discharge the settled turbid circulating water from the outer well 4; the output end of the water flow disturbance mechanism is set inside the suction well 5 to keep the turbid circulating water inside the suction well 5 in a flowing state, and during the drainage process of the drain pipe 2, the impurities in the suction well 5 are discharged together with the water. The water flow disturbance mechanism makes the water in the suction well 5 flow, which on the one hand can prevent impurities from settling and accumulating at the bottom of the suction well 5, and on the other hand can make the impurities be discharged with the water flow during the drainage process, reducing the workload and difficulty of manually cleaning the impurities in the suction well 5, and improving the efficiency and service life of the suction well 5.

[0025] In a preferred embodiment, the water flow disturbance mechanism includes a duct 7, one end of which is connected to an air source device, and the other end extends into the water intake well 5 to blow air into the water intake well 5, thereby making the turbid circulating water in the water intake well 5 flow. The method of using the duct 7 connected to the air source device to blow air to make the water flow is simple in structure and easy to implement. By blowing water with air, water circulation can be effectively formed, which can prevent the deposition of impurities.

[0026] In a preferred embodiment, the duct 7 includes a main pipe and multiple branch pipes. One end of the main pipe is connected to the air source equipment, and the other end is connected to each branch pipe. Each branch pipe is arranged vertically and is evenly arranged along the circumference of the water intake well 5. The arrangement of the main pipe and branch pipes can evenly distribute the air from the air source equipment to different circumferential positions of the water intake well 5. The vertically arranged branch pipes allow the air to act at different depths in the water intake well 5, comprehensively agitating the water in the water intake well 5, improving the uniformity and effect of water flow agitation, and better preventing impurities from settling.

[0027] In a preferred embodiment, the end of the branch pipe furthest from the main pipe is the air outlet. Each air outlet is located at a different height within the suction well 5. The air outlets at different heights allow water at different levels within the suction well 5 to be agitated by air, overcoming the problem of insufficient water agitation caused by air blowing only at a single height. This more comprehensively promotes the flow of water within the suction well 5 and enhances the effect of preventing siltation.

[0028] In a preferred embodiment, it also includes multiple arc-shaped pipes, with the air outlet end vertically fixedly connected and communicating with the middle part of the arc-shaped pipe. Air outlets are provided at both ends of the arc-shaped pipe. The arrangement of the arc-shaped pipe changes the direction and range of air blowing. Through the air outlets at both ends of the arc-shaped pipe, air can enter the water at a wider angle and direction, making the water flow more complex and diverse, and further effectively preventing impurities from settling in the local area of ​​the water intake well 5.

[0029] In a preferred embodiment, the arc-shaped pipe is set horizontally, and the center of the arc-shaped pipe is located on the axis of the water intake well 5. The horizontal setting of the arc-shaped pipe with the center located on the axis of the water intake well 5 allows the air to be evenly distributed on the cross-section of the water intake well 5, ensuring that the water in the entire cross-section of the water intake well 5 can be evenly disturbed, improving the consistency and stability of the water flow disturbance, and better realizing the function of preventing sludge sedimentation.

[0030] In a preferred embodiment, the main pipe, branch pipe, and arc pipe are made of corrosion-resistant stainless steel. Using corrosion-resistant stainless steel to make these components can effectively resist the corrosion of various chemical components in the turbid circulating water, extend the service life of the duct 7 and the arc pipe, reduce maintenance costs and replacement frequency caused by equipment corrosion damage, and improve the reliability and durability of the entire device.

[0031] In a preferred embodiment, there are two branch pipes and two arc-shaped pipes. The two branch pipes are located on both sides of the inner well 3. The specific number and location of the branch pipes and arc-shaped pipes ensure sufficient air supply and water flow disturbance. On the other hand, the reasonable layout allows the water flow in the suction well 5 to form a specific circulation path. In particular, the air blowing on both sides of the inner well 3 can better disturb the water around the inner well 3, prevent impurities from settling in this area, and at the same time help reduce unnecessary interference to the water flow of the entire suction well 5.

[0032] In a preferred embodiment, one arc-shaped pipe is located at the bottom of the suction well 5, and the other arc-shaped pipe is vertically spaced from the bottom arc-shaped pipe by 1 / 3 to 1 / 2 of the depth of the suction well 5. This vertical spacing can specifically agitate the water at different depths within the suction well 5. The bottom arc-shaped pipe can disturb the bottom water where impurities are easily deposited, while the other arc-shaped pipe at a certain distance agitates the middle layer of water, forming a layered and effective water flow agitation pattern, which comprehensively prevents sludge from settling at different depths in the suction well 5.

[0033] This utility model uses specific examples to illustrate its principles and implementation methods. The above description of the embodiments is only for the purpose of helping to understand the method and core idea of ​​this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the idea of ​​this utility model. In summary, the content of this specification should not be construed as a limitation of this utility model.
