Description

Technical Field

[0001] The utility model relates to the technical field of crystallizers, in particular to a quick-changing device for a crystallizer water inlet. Background Art

[0002] The crystallizer is a continuous steel casting equipment that receives the molten steel injected from the intermediate tank and solidifies it into a solid shell according to the specified cross-sectional shape. In some cases, the crystallizer needs to be installed with a nozzle. Installing a nozzle can effectively prevent the oxidation and splashing of the molten steel, avoid the crystallizer protective slag from being drawn into the molten steel, improve the flow state and heat flow distribution of the injection in the crystallizer, and promote the uniform growth of the shell in the crystallizer. When installing the existing nozzle of the crystallizer, it is necessary to manually lift the nozzle and connect it to the crystallizer, and it is necessary to tighten the screws and drive in the pins to fix the crystallizer and the nozzle. The installation process is relatively cumbersome, and it is time-consuming and laborious to perform the centering operation during the installation process. To this end, we propose a quick-change device for the nozzle of the crystallizer. Utility Model Content

DETAILED DESCRIPTION

[0015] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0016] See also Figure 1 and Figure 2 The utility model provides a technical solution: a quick-change device for a crystallizer water inlet, comprising a support frame 1, a side wall of the support frame 1 is provided with an assembly groove 2, a connecting component 3 is clamped in the assembly groove 2, and a guide mechanism 4 for limiting the position of the connecting component 3 is fixedly assembled on the top of the support frame 1, and a quick docking mechanism 5 is fixedly assembled on the top of the connecting component 3. The quick docking mechanism 5 is provided to achieve rapid switching between the water inlet and the crystallizer, and the use of bolts, pins and other structures is avoided during installation, which saves time and effort, and saves manpower and material resources.

[0017] like Figure 1As shown in the figure, the quick docking mechanism 5 includes a sealing quick-connect male head 51, the bottom of the sealing quick-connect male head 51 is inserted into the sealing quick-connect female head 52, the sealing quick-connect female head 52 is fixedly connected to the top of the connection component 3, and the inner cavity of the sealing quick-connect female head 52 is embedded with a sealing ring 53. The number of the sealing rings 53 is at least two groups, and the two groups of sealing rings 53 are arranged from top to bottom. The sealing rings 53 are arranged to improve the sealing performance of the sealing quick-connect male head 51 and the sealing quick-connect female head 52 after docking;

[0018] Guide ears 54 are welded and fixed to the left and right side walls of the sealing quick-connect male head 51. The guide ears 54 are provided to reduce the difficulty of docking the sealing quick-connect male head 51 and the sealing quick-connect female head 52, and improve the centering speed when the sealing quick-connect male head 51 and the sealing quick-connect female head 52 are plugged in.

[0019] The connection assembly 3 includes a first connection pipe 31, a second connection pipe 32 and a flexible joint 33. The first connection pipe 31, the second connection pipe 32 and the flexible joint 33 are respectively connected by connection flanges. The top of the first connection pipe 31 is connected and fixed to the sealing quick-connect female head 52. The connection between the first connection pipe 31 and the second connection pipe 32 is clamped in the assembly groove 2. In the process of plugging and pulling out the sealing quick-connect male head 51, the position of the first connection pipe 31 and the second connection pipe 32 can be limited by the guide mechanism 4, so as to improve the accuracy of the connection position between the first connection pipe 31, the second connection pipe 32 and the support frame 1, and the first connection pipe 31 and the second connection pipe 32 are limited and buffered. The flexible joint 33 is used to connect with the inlet and outlet water pipes on site. When the sealing quick-connect male head 51 is connected to the crystallizer, and the flexible joint 33 is connected to the inlet and outlet water pipes on site, a loop can be formed;

[0020] A water receiving tray 6 is welded and fixed on the top of the first connecting pipe 31, and a drain pipe 7 connected to the interior of the water receiving tray 6 is fixedly connected to the bottom of the water receiving tray 6. The sealing quick-connect female connector 52 is fixedly connected to the center of the water receiving tray 6 and is connected to the first connecting pipe 31. The water receiving tray 6 is provided to collect a small amount of water that overflows during the plugging and unplugging of the sealing quick-connect male connector 51, and the water is discharged to the outside.

The interior of the guide frame 41 is hollow, and the hollow guide frame 41 is provided so that it has sufficient adjustment space inside, so that when the sealing quick-connect male head 51 is plugged in and out, the connection between the first connecting pipe 31 and the second connecting pipe 32 is limited and guided, so that the connection can be moved in a small range within the guide frame 41, which plays a role in limiting and buffering the connection. The guide frame 41 is connected and fixed to the support frame 1 by fixing bolts 43.

[0022] Working principle: During use, the device first clamps the connecting component 3 into the assembly groove 2 of the support frame 1, and then fixes the guide frame 41 with the fixing bolts 43, so that the guide frame 41 clamps and limits the connecting flange between the first connecting pipe 31 and the second connecting pipe 32. When it is necessary to switch between the water inlet and the crystallizer, the sealing quick-connect male head 51 can be inserted into the sealing quick-connect female head 52, and then the flexible joint 33 is connected to the inlet and outlet water pipes on site, thereby completing a closed circuit. The device no longer needs to fix the water inlet to the crystallizer through structures such as bolts and pins through traditional methods. The water inlet and the crystallizer can be quickly switched by plugging and pulling out the sealing quick-connect male head 51, and the overflowed water can be collected and processed by the water receiving tray 6 during the plugging and pulling out of the sealing quick-connect male head 51, and the connection between the connecting component 3 and the support frame 1 can be buffered and guided by the guide mechanism 4.
