[0001] The utility model relates to the technical field of metallurgy, in particular to a device for preventing water from splashing out of a concentration tank and metallurgical equipment. Background Art
[0002] In the metallurgical industry, such as during steelmaking or steel rolling operations, the backwash water from the steelmaking high-speed filter or steel rolling high-speed filter system is generally treated by entering the sludge regulating tank through a flow channel. After being stirred by the mixer in the regulating tank, the backwash water is sent from the regulating tank to the thickening tank pump group and pumped into the sludge thickening tank. The precipitated water overflows from the overflow port above the thickening tank, and a water pipe is connected to the overflow port to recover the overflow water for reuse.
[0003] However, in the prior art, during the process of discharging the recycled water after precipitation in the above-mentioned concentration tank through the outlet pipe, air cavities are often formed in the pipe, especially when the overflow water flow is large, air cavities are more likely to appear. As the overflow water accumulates in the pipe, the air cavity bursts, and water often sprays out from the upper part of the outlet pipe, which not only affects the operating efficiency of the metallurgical equipment, but also the splashing of the overflow water in the pipe often splashes to the outside of the equipment, affecting environmental protection and polluting the environment.

The water outlet tank is used to be connected to the side wall of the concentration tank and is correspondingly communicated with the overflow port position of the concentration tank. The upper end of the water outlet pipe is communicated with the lower end of the water outlet tank. The lower end of the exhaust pipe is inserted into the upper end opening of the water outlet pipe.

[0014] Compared with the prior art, the anti-splashing water outlet device of the concentration tank provided by the utility model has the following technical effects:
[0015] The anti-splashing water discharge device for a concentration tank provided by the utility model can be used in metallurgical equipment, such as in the process of discharging overflow water from a concentration tank in steelmaking or steel rolling equipment. By arranging a water discharge tank and a water discharge pipe, the water discharge tank is connected to the overflow port position of the concentration tank, and the overflow water in the concentration tank can overflow into the water discharge tank through the overflow port, and by connecting the water discharge pipe to the lower end of the water discharge tank, the overflow water can be sent to, for example, a recovery device through the water discharge pipe to perform the water discharge operation of the overflow water in the concentration tank. At the same time, by arranging an exhaust pipe, and inserting the lower end of the exhaust pipe into the upper end opening of the exhaust pipe, the upper end of the exhaust pipe is higher than the upper end of the water discharge tank, that is, the upper end of the exhaust pipe is higher than the water surface of the overflow water in the water discharge tank. The exhaust pipe and the water outlet pool are connected by a bracket, and the exhaust pipe is stably supported and connected and fixed, so that the air cavity generated in the water outlet pipe during the water outlet operation can be discharged through the exhaust pipe when it rises to the exhaust pipe position to relieve the pressure, thereby preventing the splashing of overflow water. At the same time, the exhaust pipe inserted into the water outlet pipe can also prevent the formation of an air cavity that can produce splashing in the water outlet pipe to a certain extent, which can effectively prevent the splashing of overflow water during the water outlet operation of the concentration tank, and thus increase the flow rate of overflow water, that is, improve the water outlet operation efficiency of the concentration tank, and improve the operation efficiency of metallurgical equipment.

Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or implementations in a suitable manner.
[0028] To solve the above technical problems, Figure 1 As shown, an embodiment of the utility model provides a splash-proof water outlet device for a concentration tank, comprising a water outlet tank 10, a water outlet pipe 20, an exhaust pipe 30 and a bracket, wherein the water outlet tank 10 is used to be connected to the side wall of the concentration tank and corresponds to the overflow port position of the concentration tank, the water outlet pipe 20 is connected to the lower end of the water outlet tank 10, the lower end of the exhaust pipe 30 is inserted into the upper end of the water outlet pipe 20, the upper end of the exhaust pipe 30 is higher than the upper end of the water outlet tank 10, one end of the bracket is connected to the exhaust pipe 30, and the other end of the bracket is connected to the water outlet tank 10.
[0029] It should be noted that the outlet pool 10 of the present anti-splashing water outlet device of the concentration pool is a pool body structure, that is, the upper end is an open structure, and the whole can be made of, for example, a steel plate or a reinforced concrete structure, and is side-hung and connected to the upper end of the side wall of the concentration pool of metallurgical equipment such as steelmaking or steel rolling. Accordingly, an overflow port can be provided at the upper end of the side wall of the concentration pool, and the turbid water such as mud in the concentration pool overflows from the top of the concentration pool to the outlet pool 10 after sedimentation, and flows out through the outlet pipe 20 for reuse, for example, flows out through the outlet pipe 20 to the steel rolling turbid ring water pool for use. The sludge after the addition and sedimentation of the concentration pool is scraped to the central part of the bottom of the concentration pool by the bottom concentration pool scraper, and then sent to the plate and frame filter press pump group from the concentration pool to the plate and frame filter press. The mud cake after dehydration treatment by the plate and frame filter press is stored in the mud storage hopper and regularly transported by, for example, a car. In the prior art, in order to prevent overflow water from splashing, some covers are added to the overflow port and the water pipe to prevent overflow water from splashing outside. However, since the pressure generated when the air cavity in the pipe is out of the water surface is relatively large, it will impact the cover plate or the upper cover and other structures, making the upper cover or the cover plate easy to fall off, which may cause damage to people or objects. Through the exhaust pipe 30 of the anti-splashing water outlet device of the concentration tank of this embodiment, the air cavity generated in the pipe can be exploded and depressurized, so that splashing will not occur, thereby improving the safety of operation, and being environmentally friendly and reliable, and having high operation efficiency.
[0030] Specifically, the exhaust pipe 30 passes through the lower end of the water outlet pool 10, that is, the bottom end, and is inserted into the water outlet pipe 20. The insertion depth or the length of the exhaust pipe 30 is designed according to the actual situation, as long as it does not hinder the drainage of the water outlet pipe 20 and can prevent the formation and elimination of air cavities. No specific limitation is made here. Figure 1 To Attachment Figure 3 The bracket is composed of two or three support rods 40 as shown in the figure. Accordingly, as long as the bracket can stably connect and fix the exhaust pipe 30 relative to the water outlet pool 10, its specific structure is not specifically limited here.
[0031] In the present embodiment, the anti-splashing water discharge device of the concentration tank provided in the present embodiment can be used in metallurgical equipment, such as in the overflow water discharge process of the concentration tank in steelmaking or steel rolling equipment. By setting a water discharge tank 10 and a water discharge pipe 20, the water discharge tank 10 is connected to the overflow port position of the concentration tank, and the overflow water in the concentration tank can overflow into the water discharge tank 10 through the overflow port, and by connecting the water discharge pipe 20 to the lower end of the water discharge tank 10, the overflow water can be sent to, for example, a recovery device through the water discharge pipe 20 to perform the water discharge operation of the overflow water of the concentration tank. At the same time, by setting an exhaust pipe 30, and inserting the lower end of the exhaust pipe 30 into the upper end opening of the exhaust pipe 20, the upper end of the exhaust pipe 30 is higher than the upper end of the water discharge tank 10, that is, the upper end of the exhaust pipe 30 is higher than the upper end of the water discharge tank 10. The surface of the overflow water is determined, and the exhaust pipe 30 is connected to the water outlet pool 10 through a bracket, and the exhaust pipe 30 is stably supported, connected and fixed, so that the air cavity generated in the water outlet pipe 20 during the water outlet operation can be discharged through the exhaust pipe 30 when it rises to the position of the exhaust pipe 30 to relieve the pressure, thereby preventing the splashing of the overflow water. At the same time, the exhaust pipe 30 inserted into the water outlet pipe 20 can also prevent the formation of an air cavity that can generate splashing in the water outlet pipe 20 to a certain extent, which can effectively prevent the overflow water from splashing during the water outlet operation of the concentration tank, and thus increase the flow rate of the overflow water, that is, improve the water outlet operation efficiency of the concentration tank, and improve the operation efficiency of the metallurgical equipment. At the same time, the overflow water will not overflow or splash, and the surrounding environment and personnel are effectively protected.
[0032] Alternatively, if Figures 1 to 3 As shown, the water outlet pipe 20 and the exhaust pipe 30 are both arranged vertically.
[0033] Specifically, the water outlet pipe 20 and the exhaust pipe 30 are both circular tube structures, and their axes are perpendicularly arranged to the bottom wall of the water outlet pool 10, which is more convenient for efficient drainage.
[0034] In this embodiment, by vertically arranging the water outlet pipe 20 and the exhaust pipe 30, the overflow water in the concentration tank can be drained more smoothly through the water outlet pipe 20 due to gravity. At the same time, due to the principle that gas rises in water, the vertical arrangement of the exhaust pipe 30 also facilitates the elimination of the air cavity, that is, it is more convenient to discharge the gas.
[0035] Alternatively, if Figures 1 to 3 As shown, the water outlet pipe 20 and the exhaust pipe 30 are coaxially arranged.
[0036] Specifically, the water outlet pipe 20 and the exhaust pipe 30 are both circular pipe structures, the diameter of the exhaust pipe 30 is smaller than the diameter of the water outlet pipe 20 , and part of the exhaust pipe 30 is located inside the water outlet pipe 20 .
[0037] In this embodiment, by coaxially arranging the water outlet pipe 20 and the exhaust pipe 30, on the one hand, the air cavity formed in the water outlet pipe 20 can be eliminated and exhausted evenly, and the anti-splashing effect is better. On the other hand, the water outlet pipe 20 can also drain water more evenly and reliably, and is less likely to produce turbulence and the like, and the drainage is more stable and reliable.
[0038] Alternatively, if Figure 1 and Figure 2 As shown, the bracket includes a support rod 40 , one end of the support rod 40 is connected to the exhaust pipe 30 , and the other end of the support rod 40 is connected to the upper end of the water outlet pool 10 .
[0039] Specifically, the two support rods 40 are symmetrically arranged on both sides of the exhaust pipe 30, and the support structure is more stable and reliable. The support rods 40 are long strip structures, which do not hinder the water inlet of the water outlet pool 10. At the same time, the structural complexity is reduced, the weight of the overall structure is reduced, and the installation is convenient.
[0040] In this embodiment, the exhaust pipe 30 is supported and fixed by using the support rod 40 as a bracket, which is convenient for installation. At the same time, two support rods 40 can be symmetrically arranged on both sides of the exhaust pipe 30, so that the support and fixation of the exhaust pipe 30 is more stable and reliable.
[0041] Alternatively, if Figure 3 As shown, the bracket includes a plurality of support rods 40 , and the plurality of support rods 40 are evenly distributed along the circumference of the exhaust pipe 30 .
[0042] Exemplarily, there are three support rods 40, which are evenly distributed along the circumference of the exhaust pipe 30. The lengths of the three support rods 40 can be designed according to the structural dimensions of the water outlet pool 10 as long as they can be stably connected and fixed.
[0043] In this embodiment, a plurality of support rods 40 are provided as brackets to support and fix the exhaust pipe 30, and the plurality of support rods 40 are evenly distributed around the circumference of the exhaust pipe 30, so that the support and fixation of the exhaust pipe 30 is more stable and reliable, and a three-point or more support positioning structure can be formed to prevent the exhaust pipe 30 from rotating, flipping, and other unstable situations, thereby further improving the stability and reliability of the overall structure.
[0044] Optionally Figures 1 to 3 As shown, one end of the support rod 40 is welded to the outer wall of the exhaust pipe 30 , and the other end of the support rod 40 is overlapped with the upper end of the water outlet pool 10 .
[0045] Specifically, the exhaust pipe 30 is a metal pipe, and the support rod 40 is also made of metal material, which is more firm and reliable.
[0046] In this embodiment, by welding and fixing one end of the support rod 40 to the exhaust pipe 30, the structure is more solid and stable, and the exhaust pipe 30 can be firmly supported and fixed. At the same time, by overlapping the other end of the support rod 40 on the upper end of the water outlet pool 10, the support rod 40 and the exhaust pipe 30 can be conveniently removed as a whole to replace parts, perform maintenance and the like, and facilitate overall disassembly and maintenance.
[0047] Alternatively, if Figures 1 to 3 As shown, the cross section of the support rod 40 is in a “V”-shaped structure, and the opening surface of the “V”-shaped structure of the support rod 40 overlaps with the upper end surface of the water outlet pool 10 .
[0048] Specifically, the support rod 40 can be an angle steel, which is easy to purchase and has a firm structure. The angle steel can be buckled on the upper end surface of the water outlet pool 10, and the structure is more stable.
[0049] In this embodiment, by setting the cross-section of the support rod 40 to a "V"-shaped structure, that is, the support rod 40 is a structure such as an angle steel, and the opening surface of the "V"-shaped structure is overlapped with the upper end surface of the water outlet pool 10, it is equivalent to that one support rod 40 has two overlapping surfaces overlapping the water outlet pool 10, that is, the exhaust pipe 30 can be supported and fixed with two supporting surfaces by one support rod 40, the structure is more stable and reliable, and the support rod 40 can be prevented from rotating on the upper end surface of the water outlet pool 10, that is, the exhaust pipe 30 is prevented from rotating or flipping, thereby further improving the stability and reliability of the overall structure.
[0050] Alternatively, if Figures 1 to 3 As shown, a water inlet 11 is provided at the upper end of the side wall of the water outlet pool 10, and the water inlet 11 is used to be connected to the overflow port of the concentration pool accordingly.
[0051] Specifically, the water inlet is a notch structure opened at the upper end of the side wall connecting the outlet tank 10 and the concentration tank, which is more convenient for the inflow of overflow water.
[0052] In this embodiment, by opening a water inlet 11 at the upper end of the side wall of the water outlet pool 10 and correspondingly connecting the water inlet 11 to the overflow port of the concentration pool, the overflow water can be introduced into the water outlet pool 10 more smoothly and accurately, which makes drainage easier and prevents overflow water from overflowing, further improving the reliability and environmental protection of the overall structure.
[0053] Alternatively, if Figure 2 and Figure 3 As shown, a water outlet 12 adapted to be connected to the upper end of the water outlet pipe 20 is provided at the lower end of the water outlet pool 10 , and the water outlet 12 is opened at the center position of the lower end of the water outlet pool 10 .
[0054] Specifically, the water outlet 12 is a circular hole structure, which is compatible with the shape of the upper end of the water outlet pipe 20. The upper end of the water outlet pipe 20 can be inserted into the water outlet 12 or connected to the lower end of the water outlet 12, which is not specifically limited here.
[0055] In this embodiment, a water outlet 12 is opened at the center position of the lower end of the water outlet pool 10 to match and connect with the upper end of the water outlet pipe 20, so that the overflow water in the water outlet pool 10 can flow into the water outlet pipe 20 more smoothly and quickly, and the flow rate is more uniform, thereby preventing turbulence from occurring in the water outlet pool 10. This is equivalent to reducing the probability of air cavities forming in the water outlet pipe 20, thereby further improving the water outlet efficiency.
[0056] In addition, another embodiment of the utility model provides a metallurgical equipment, including the above-mentioned concentration tank anti-splashing water device.
[0057] Exemplarily, the metallurgical equipment is a steel rolling equipment or a steelmaking equipment, and in the turbid water circulation system in the above equipment, for example, the concentration tank is connected to use the present concentration tank anti-splashing water outlet device.
[0058] In this embodiment, the metallurgical equipment described in this embodiment has substantially the same technical effect as the above-mentioned concentrating tank anti-splashing device by setting the above-mentioned concentrating tank anti-splashing device, which will not be described in detail here.
[0059] Although the utility model is disclosed as above, the protection scope of the utility model is not limited thereto. Those skilled in the art may make various changes and modifications without departing from the spirit and scope of the utility model, and these changes and modifications will fall within the protection scope of the utility model.
