Description

Technical Field

[0001] This utility model relates to the field of spraying technology, specifically to an emulsion spraying device for hot rolling rolls. Background Technology

[0002] During the hot rolling process, the workpiece temperature is usually quite high. The high temperature of the workpiece will generate heat radiation on the rolls. In the rolling deformation zone, the rolls and workpiece are in direct contact. The large temperature difference between the two causes the heat of the workpiece to be transferred to the surface of the rolls. The intense plastic deformation of the workpiece during rolling will generate a lot of heat. The friction between the rolls and the workpiece will also generate heat. Some of this heat will be transferred to the surface of the rolls. All of these factors will cause the surface temperature of the rolls to rise. In order to avoid thermal fatigue damage to the roll surface and extend the service life of the rolls as much as possible, it is necessary to spray emulsion on the roll surface for cooling.

[0003] Existing emulsion spraying devices for hot rolling rolls are generally fixed conveying pipes on the hot rolling mill. The nozzles on the pipes are usually arranged at equal intervals. However, when the width of the hot-rolled sheet is insufficient, some of the liquid sprayed from the nozzles will not be able to cool the sheet, which will affect the spraying effect. Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide an emulsion spraying device for hot rolling rolls to solve the technical problem that some of the liquid sprayed from the nozzles cannot cool the sheet metal, which in turn affects the spraying effect.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an emulsion spraying device for hot rolling rolls, including a fixing clamp for fixing the original spray pipe, a mounting plate is provided on one side of the fixing clamp, a first connector is provided on the mounting plate, a universal hose is threadedly connected to one side of the first connector, and a conduit is threadedly connected to the other side of the first connector.

[0006] By adopting the above technical solution, the fixing clamp can firmly fix the mounting plate to the original spray pipe, ensuring the stability and reliability of the entire emulsion spray device. The first joint on the mounting plate is connected to the universal hose and the conduit by thread. This connection method is not only firm and reliable, but also easy to disassemble and replace.

[0007] Furthermore, one end of the conduit is connected to a sampling mechanism, which includes a connecting tube with an installation groove.

[0008] By adopting the above technical solution, the sampling mechanism connected to one end of the conduit facilitates the quality monitoring of the emulsion. The connecting tube in the sampling mechanism serves as a channel for the flow of the emulsion, ensuring that the emulsion can flow smoothly.

[0009] Furthermore, a transparent observation window is fixedly connected inside the mounting slot, and the observation window is configured with a keyway-shaped structure.

[0010] By adopting the above technical solution, the transparent observation window fixedly connected inside the installation tank allows operators to directly observe the flow status of the emulsion in the connecting pipe without disassembling any parts.

[0011] Furthermore, a branch pipe is provided below the connecting pipe, and the branch pipe is used to sample the emulsion.

[0012] By adopting the above technical solution, the branch pipe set below the connecting pipe provides a dedicated channel for sampling the emulsion, enabling operators to easily obtain emulsion samples from the branch pipe without interfering with the main emulsion flow channel, thus ensuring the convenience and safety of sampling.

[0013] Furthermore, two fixing clips are provided, and the two fixing clips are fixedly connected to the mounting plate. One end of the universal hose is fixedly connected to the nozzle.

[0014] By adopting the above technical solution, the fixed connection between the two fixing clips and the mounting plate enhances the stability and reliability of the entire emulsion spraying device. The two fixing clips can be fixed to the original spraying pipes respectively to form a stable support point, effectively preventing the spraying device from moving or loosening due to vibration or external force during operation.

[0015] Furthermore, fixing rings are fitted on both sides of the connecting tube, and a magnet is fixedly connected to one end of each fixing ring.

[0016] By adopting the above technical solution, the fixing rings sleeved on both sides of the connecting pipe provide support and fixation for the sampling mechanism. The fixing rings can be tightly sleeved on the connecting pipe, and the sampling mechanism can be firmly adsorbed onto the outer shell of the hot rolling equipment or other metal parts through the magnet fixedly connected to one end of the rings.

[0017] Furthermore, a magnetic base is fixedly connected to one end of the fixing ring.

[0018] By adopting the above technical solution, the magnetic base can not only provide strong adsorption force to ensure that the sampling mechanism is firmly fixed on the shell of the hot rolling equipment or other metal parts, but also easily realize the quick installation and disassembly of the sampling mechanism through its internal magnetic adjustment mechanism.

[0019] In summary, the present invention has the following main advantages:

[0020] 1. This utility model, by setting up fixing clips, mounting plates, and universal hoses, can flexibly increase the number of fixing clips and corresponding components according to the scale of the hot rolling mill and the spraying requirements, thereby installing multiple emulsion spraying devices. This ensures that more comprehensive spraying coverage can be achieved according to the width and length of the plate, greatly improving the efficiency and uniformity of spraying. The sampling mechanism is attracted to the outer shell of the hot rolling equipment by magnets, ensuring the fixed and stable fixation of the sampling mechanism and avoiding loosening or falling off the sampling mechanism due to vibration or external force, thus ensuring installation reliability. During the spraying process, the emulsion can be observed through the observation window, and abnormalities in the emulsion, such as color changes and impurities, can be detected in time. Sampling can be carried out through branch pipes and laboratory analysis can be performed to ensure that its quality meets production requirements. This improves the real-time and accuracy of emulsion quality monitoring, ensuring the stability of the production process and product quality.

[0021] 2. By setting up a sampling mechanism, this utility model can easily obtain samples from the emulsion flow channel for operators to perform subsequent quality analysis. The sampling mechanism is fixed by a magnetic base, which enhances the stability of the sampling mechanism and makes the disassembly process simpler. Attached Figure Description

[0027] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0028] The embodiments of this utility model will be described below based on its overall structure.

[0029] Example 1:

[0030] An emulsion spraying device for hot rolling rolls, such as Figures 1-4 As shown, the device includes a fixing clip 1 for fixing the original spray pipe. A mounting plate 2 is provided on one side of the fixing clip 1. A first connector 3 is provided on the mounting plate 2. A universal hose 4 is threadedly connected to one side of the first connector 3, and a conduit 5 is threadedly connected to the other side of the first connector 3. The introduction of the universal hose 4 allows the spray angle and position to be flexibly adjusted according to the width and shape of the hot-rolled sheet, ensuring that the emulsion can be sprayed evenly and accurately on the surface of the sheet, thereby improving the coverage and uniformity of the spray.

[0031] See Figure 1 , Figure 2 and Figure 3 One end of the conduit 5 is connected to a sampling mechanism 6. The sampling mechanism 6 includes a connecting pipe 601. An installation groove 602 is provided on the connecting pipe 601. The installation groove 602 on the connecting pipe 601 provides space for the installation of the observation window, which can monitor the state of the emulsion in real time and ensure that the quality of the emulsion meets the production requirements.

[0032] See Figure 1 , Figure 2 and Figure 3 A transparent observation window 603 is fixedly connected inside the mounting slot 602. The observation window 603 has a keyway structure. The keyway structure of the observation window 603 not only enhances the connection strength between it and the connecting pipe 601, but also ensures the stability and durability of the observation window.

[0033] See Figure 1 , Figure 2 and Figure 3 A branch tube 604 is provided below the connecting tube 601, and the branch tube 604 is used to sample the emulsion. The design of the branch tube 604 also takes into account the representativeness of the sampling. It can directly obtain the emulsion from the connecting tube 601, ensuring that the sample can truly reflect the overall quality of the emulsion.

[0034] See Figure 1 , Figure 2 and Figure 3 There are two fixing clips 1, which are fixedly connected to the mounting plate 2. One end of the universal hose 4 is fixedly connected to the nozzle 10. The nozzle 10 fixedly connected to one end of the universal hose 4 ensures that the emulsion can be sprayed evenly and accurately on the hot-rolled plate. The flexibility of the universal hose 4 allows the position and angle of the nozzle 10 to be flexibly adjusted according to actual needs, thereby achieving comprehensive and uniform spraying of the hot-rolled plate.

[0035] See Figure 1 , Figure 2 and Figure 3The connecting tube 601 is fitted with fixing rings 7 on both sides. A magnet 8 is fixedly connected to one end of the fixing ring 7. The operator can easily use the attraction of the magnet 8 to attract the sampling mechanism 6 to a suitable position without the need for additional fixing tools or complicated installation steps, saving installation time and reducing the labor intensity during the installation process.

[0036] The principle of this utility model is as follows: First, the number of fixing clamps 1 and corresponding components can be increased according to the scale of the hot rolling mill and the spraying requirements, and multiple emulsion spraying devices can be installed to achieve more comprehensive spraying coverage according to the width and length of the plate.

[0037] Then, the mounting plate 2 is securely fixed to the original spray pipe using the fixing clip 1, and the universal hose 4 is connected to the conduit 5 on the mounting plate 2 through the first connector 3. The flexibility of the universal hose 4 allows the spray angle and position to be adjusted according to the width and shape of the hot-rolled plate, ensuring that the emulsion can be sprayed evenly on the surface of the plate. Then, the sampling mechanism 6 is attracted to the outer shell of the hot rolling equipment by the magnet 8 to ensure a secure fixation.

[0038] One end of the connecting pipe 601 is connected to an external pump through a pipe, so that the emulsion can be pumped into the spraying system by the external pump, ensuring that the emulsion flows in the pipe and is evenly sprayed onto the hot-rolled plate through the nozzle 10 at the end of the universal hose 4.

[0039] During the spraying process, the emulsion can be observed through the observation window 603. If the color of the emulsion is found to be incorrect, it can be sampled through the branch pipe 604 and analyzed in the laboratory to ensure that its quality meets the production requirements.

[0040] Example 2:

[0041] See Figure 4 One end of the fixing ring 7 is fixedly connected to a magnetic base 9. The introduction of the magnetic base 9 has greatly improved the flexibility and convenience of the sampling mechanism installation. According to actual needs, the magnetic force of the magnetic base 9 can be easily adjusted to achieve quick and labor-saving disassembly, thus improving work efficiency.

[0042] The implementation principle of this utility model is as follows: First, the sampling mechanism 6 is fixed by the magnetic base 9, so that the sampling mechanism can be quickly removed by rotating the knob on the magnetic base 9 during disassembly, reducing the force required for disassembly.

[0043] All parts not covered in this utility model are the same as or can be implemented using existing technologies, and will not be described in detail here.
