Description

Technical Field

[0001] The utility model relates to the technical field of metallurgical cooling, in particular to a side-spraying drainage device. Background Art

[0002] As competition in the steel industry becomes increasingly fierce, manufacturers are paying more and more attention to exploring methods to reduce costs and increase efficiency. Among them, in the metallurgical hot rolling production line, the strip steel needs to enter the laminar cooling system for cooling after being rolled by the finishing mill, that is, the upper and lower water collecting pipes of the cooling system are used to cool the upper and lower surfaces of the strip steel. The upper and lower cooling headers of the laminar cooling system are arranged in groups. In the actual cooling process of the steel strip, the upper cooling water will remain on the surface of the steel strip after spraying, and the retention of water will affect the spraying effect of the next group of cooling water. At the same time, the randomness of the flow of the retained water will also cause uneven cooling of the steel strip surface. Therefore, it is necessary to configure a side spray collector on one side of the side guide plate of the strip transport roller between each group of upper and lower cooling headers, and use the high-pressure water spray blown out of the water spray pipe to blow away the retained water on the surface of the steel strip.

[0003] In actual use, although high-pressure side water spray can purge the retained water on the strip surface, the water spray will form back splashing water after being sprayed onto the other side guide plate or the steam trap with poor water drainage, which will cause the spray water to remain on the surface of the steel strip. At the same time, the water splashing out of the side guide plate is also likely to damage the bearings and motors of the transport roller and other equipment, causing abnormal downtime and increasing maintenance costs. Therefore, how to prevent the splashing cooling water from reflecting back onto the strip is a difficult problem that needs to be solved in this field at this stage. Summary of the invention

[0004] In view of the above problems in the prior art, the purpose of the utility model is to provide a side-spraying drainage device, which can prevent the splashing cooling water from being reflected onto the strip again.

[0006] Furthermore, every four vertical plates form a group, and the four vertical plates are arranged in a diamond shape, with gaps between adjacent vertical plates, and multiple groups of vertical plates arranged in a diamond shape are evenly welded and distributed on the inner side of the rear wall of the cavity.

[0021] The following are specific embodiments of the present invention, which further describe the technical solution of the present invention, but the protection scope of the present invention is not limited to these embodiments. Any changes or equivalent substitutions that do not deviate from the concept of the present invention are included in the protection scope of the present invention.

[0022] like Figure 1 , 2 As shown, a side spray drainage device includes a body 1, wherein a cavity is provided in the body 1, the front side of the cavity is hollowed out, a water tank 7 for cooling water to enter and exit is provided at the bottom of the cavity, a plurality of drain ports 8 are provided on the water tank 7, a crossbeam 3 is provided at the upper part of the cavity, both ends of the crossbeam 3 are connected and fixed to the body 1, a plurality of chains 4 are hung on the crossbeam 3, the chains 4 are used to weaken the kinetic energy of the cooling water entering the cavity, a plurality of vertical plates 2 arranged in a certain pattern are fixedly installed on the rear wall of the cavity, the vertical plates 2 are used to further consume the kinetic energy of the cooling water. After being reflected, the cooling water will impact the chain 4, and the kinetic energy will be further consumed. The cooling water with the kinetic energy lost will fall into the cavity structure under the action of the chain 4, and enter the cooling system from the drain port 8. During the cooling process, when the cooling water splashes, part of the cooling water will enter the drain device through the water tank 7 and directly enter the drain port 8, while most of the cooling water will impact the chain 4 and the vertical plate 2, and its kinetic energy will be absorbed and then fall into the cavity structure; the cooling water whose kinetic energy is consumed will enter the laminar cooling system through the drain port 8. This process prevents the splashed cooling water from being reflected on the strip again.

[0023] Pin holes are respectively provided on the left and right side walls of the body 1, and the two ends of the crossbeam 3 are respectively connected to the pin holes. In order to allow the cooling water entering the cavity structure to release the residual kinetic energy as quickly as possible, the chain 4 is hung on the crossbeam 3, and the chain 4 is welded to the crossbeam 3. Figure 1 In order to clearly show the arrangement of the vertical boards 2, the chain 4 on the crossbeam 3 is only partially shown and is not completely drawn.

[0024] The bottom plate of the body 1 is provided with screw holes 6, and the body 1 is installed in the laminar cooling system through the screw holes 6 by means of bolts or screws.

[0025] The two ends of the body 1 are respectively connected with connecting plates 9, which are used to be fixedly connected with the side baffles to prevent the strip from running off. In order to facilitate the installation of the connecting plate 9, through holes, slots, etc. can be set at corresponding positions on the connecting plate 9, and the connection method between the connecting plate 9 and the side baffle includes but is not limited to threaded screw connection or slot clamping method. In this embodiment, a through hole 5 is provided on the connecting plate. During operation, the connecting plate can be connected to the side baffle by steel wire, screw nut, etc.

[0026] There are multiple water troughs 7. In order to allow as much cooling water as possible at a low splashing position to enter the cavity structure, the grooving direction of the water trough 7 can be set to be consistent with the direction of cooling water outflow. The water trough 7 is set at a proper distance from the bottom plate to prevent the backflow of cooling water.

[0027] In a preferred embodiment of the utility model, every four vertical plates 2 form a group, and the four vertical plates 2 are arranged in a diamond shape, with gaps between adjacent vertical plates 2, and multiple groups of vertical plates 2 arranged in a diamond shape are evenly welded and distributed on the inner side of the rear wall of the cavity.

[0028] In a preferred embodiment of the present invention, Figure 3 As shown, the cross beam 3 is provided with an external thread, and the pin holes on the left and right side walls of the main body 1 are provided with internal threads, and the cross beam 3 is fixedly connected with the main body 1 through threads.

[0029] In a preferred embodiment of the utility model, the body 1 is provided with a certain chamfer to prevent the strip steel passing at high speed from hitting the steel, thereby ensuring the smooth passage of the strip steel.

[0030] The side-spraying drain device of the utility model is fixed to the laminar cooling system through the bottom plate, and is provided with a plurality of drain ports 8. Since screw holes 6 are provided on the bottom plate, installation is relatively convenient; and connecting plates 9 are provided at both ends of the main body 1, which facilitate the connection of the drain device with the side baffles, and do not affect the high-speed passage of the strip. In actual use, the side-sprayed cooling water falls on the strip, and after the strip is cooled, the splashing cooling water with low kinetic energy directly enters the drain port 8 in the cavity structure through the water trough 7, and the cooling water with high kinetic energy will consume kinetic energy under the action of the chain 4, and part of the cooling water will also impact the vertical plate 2. After rebounding, most of the kinetic energy of the cooling water is absorbed, and the chain 4 will also prevent the cooling water from further splashing back onto the strip, and the cooling water whose kinetic energy is consumed will flow into the laminar cooling system through the drain port 8.

[0031] The installation method of the side spray drain device of the utility model comprises the following steps:

[0032] 1) Take four vertical plates 2 as a group, arrange them in a rhombus shape, leave a certain gap between the vertical plates 2 and weld them to the inner side of the rear wall of the cavity of the main body 1, and set multiple groups of rhombuses and weld them regularly on the rear wall of the cavity of the main body 1;

[0033] 2) Insert the crossbeam 3 from the pin hole on one side wall of the body 1, and then hang a number of chains 4 on the crossbeam 3. The crossbeam 3 continues to pass through the pin hole on the other side wall of the body 1, and then rotates and tightens;

[0034] 3) Distribute the chains 4 evenly on the crossbeam 3 and fix them on the crossbeam 3 by welding;
