Description

Technical Field

[0001] This application relates to the technical field of galvanizing finishing machines, and in particular to a spraying system for galvanizing finishing machines. Background Technology

[0002] As a device for improving the surface quality and smoothness of products, the finishing machine usually rolls products using work rolls and support rolls. Both the work roll and the support roll consist of three parts: the roll body, the roll neck, and the shaft head. During installation, the shaft head is rotatably connected to the frame of the finishing machine, and the frame is equipped with a motor that drives the work roll and the support roll to rotate.

[0003] If rolling oil and contaminants remain on the surface of the strip and are not thoroughly cleaned, they can easily adhere to the surfaces of the work rolls and support rolls during the rolling process of the strip mill. In order to reduce the possibility of zinc powder adhering to the surfaces of the work rolls and support rolls being pressed into the strip, it is usually necessary to clean the work rolls and support rolls.

[0004] The common cleaning method involves manually mixing the finishing solution and water in a storage tank at a certain ratio, and then conveying it through pipelines to the spray devices installed on the frame and corresponding to the working roller and support roller respectively. When the staff observes that the mixture in the storage tank is low, they mix the finishing solution and water again and then introduce it into the storage tank. This method may result in high labor intensity for the staff. Utility Model Content

[0005] To reduce labor intensity, this application provides a spraying system for galvanized finishing machines.

[0006] The galvanizing bright finish machine spraying system provided in this application adopts the following technical solution: A galvanizing finishing machine spraying system includes spray pipes mounted on a frame and corresponding to rollers one by one. Each spray pipe is equipped with a plurality of nozzles facing the corresponding roller. A storage tank connected to the spray pipe and storing a mixed liquid is provided on the side of the frame away from the spray pipe. An inlet pipe for conveying finishing liquid is installed on one side of the storage tank, and an inlet pipe for conveying demineralization water is installed on the other side of the storage tank. An automatic dispensing component is installed on the storage tank to drive the finishing liquid and demineralization water into the storage tank.

[0007] By adopting the above technical solution, the automatic dispensing component drives the water inlet pipe and liquid inlet pipe to transport the demineralized water and finishing liquid to the storage tank for mixing. The mixed liquid then enters each spray pipe and is sprayed onto the corresponding rollers through the nozzles, which facilitates the cleaning of the rollers and reduces the possibility of manually observing the amount of mixed liquid in the storage tank, thus reducing labor intensity.

[0008] Optionally, the automatic dispensing assembly includes a first solenoid valve installed on the inlet pipe, a second solenoid valve installed on the water inlet pipe, and a monitoring device for monitoring the liquid level of the mixture in the storage tank.

[0009] By adopting the above technical solution, the liquid level of the mixed liquid in the storage tank is monitored by the monitoring device. When the liquid level of the mixed liquid in the storage tank is low, the first and second solenoid valves are opened. At this time, the water inlet pipe delivers the demineralized water to the storage tank, and the liquid inlet pipe delivers the finishing liquid to the storage tank, which facilitates the mixing of the finishing liquid and the demineralized water. When the monitoring device detects that the liquid level of the mixed liquid in the storage tank reaches the high level, the first and second solenoid valves are closed, thereby blocking the water inlet pipe and the liquid inlet pipe. This makes it easier to monitor and control the liquid level of the mixed liquid in the storage tank and reduces labor intensity.

[0010] Optionally, the monitoring device includes a liquid level sensor installed in the storage tank.

[0011] By adopting the above technical solution, the liquid level of the mixed liquid in the storage tank is monitored by a liquid level sensor, which facilitates the control of the water inlet pipe and liquid inlet pipe to replenish the demineralization water and finishing liquid into the storage tank. At the same time, it is easy to control the water inlet pipe and liquid inlet pipe to stop the delivery, reducing the possibility of manual observation and achieving the effect of reducing labor intensity.

[0012] Optionally, each of the spray pipes is fixedly connected to and communicates with a delivery pipe that is connected to the inside of the storage tank at the same end. A water pump is installed on the delivery pipe. An installation pipe is installed on the upper side of the delivery pipe along the height direction of the storage tank. A fixing pipe facing the storage tank is installed on the upper end of the installation pipe. The fixing pipe is bent downward and inserted into the storage tank.

[0013] By adopting the above technical solution, during the process of the water pump driving the mixed liquid in the storage tank to be transported to the spray pipe through the delivery pipe, part of the mixed liquid is transported to the storage tank through the installation pipe and the fixed pipe. At this time, the high-speed mixed liquid flowing out from the end of the fixed pipe mixes with the mixed liquid in the storage tank and mixes and stirs the finishing liquid and demineralized water transported to the storage tank, which facilitates the mixing of the replenished finishing liquid and demineralized water and improves work efficiency.

[0014] Optionally, both the water inlet pipe and the liquid inlet pipe are equipped with manual valves to control the flow rate of the pipes.

[0015] By adopting the above technical solution, the flow rate of the water inlet pipe and liquid inlet pipe can be controlled by the manual valve, which facilitates the control of the ratio of finishing liquid and demineralized water entering the storage tank and improves work efficiency.

[0016] Optionally, a connecting pipe facing the storage tank is installed on the upper side of the water inlet pipe. The connecting pipe is bent downward and inserted into the storage tank, and a spiral nozzle is installed at one of the bent ends of the connecting pipe.

[0017] By adopting the above technical solution, during the process of transporting the demineralized water to the storage tank through the inlet pipe, part of the demineralized water is transported to the spiral nozzle through the connecting pipe and sprayed out. At this time, the high-speed demineralized water sprayed into the storage tank and defoams the foam generated by mixing in the storage tank, reducing the possibility of the foam continuing to rise and overflowing from the top of the storage tank, thereby reducing waste and improving the utilization rate of the mixed liquid.

[0018] Optionally, an air knife is installed on the side of the frame near the spray pipe, corresponding to the roller body and arranged along the length of the roller body. The air knife is located on the lower side of the corresponding spray pipe, and the side of the air knife near the roller body is inclined downward.

[0019] By adopting the above technical solution, after the spray pipe cleans the roller body through the nozzle, the air knife blows the rotating roller body to remove the residual mixture on the roller body, thereby reducing the possibility of the mixture adhering to the roller body surface and forming impurity particles, and reducing the adverse effects on strip rolling.

[0020] Optionally, each of the rollers is provided with a sponge on one side that is close to the other. The sponge moves along the length of the roller and can contact the sidewalls of the two adjacent rollers. The frame is provided with a drive unit to drive the sponge to move.

[0021] By adopting the above technical solution, after the air knife blowing is completed, the driving component drives the sponge to move along the length of the roller body, thereby further wiping away the residual mixture on the surface of the roller body, reducing the possibility of the mixture adhering to the surface of the roller body, and reducing the adverse effects on strip rolling.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. The automatic dispensing component drives the water inlet pipe and liquid inlet pipe to deliver the demineralized water and finishing liquid to the storage tank for mixing, reducing the possibility of manually observing the amount of mixed liquid in the storage tank and reducing labor intensity; 2. When the liquid level of the mixed liquid in the storage tank is low, the first and second solenoid valves are opened. At this time, the water inlet pipe delivers the demineralized water to the storage tank, and the liquid inlet pipe delivers the finishing liquid to the storage tank, which facilitates the mixing of the finishing liquid and the demineralized water. When the monitoring device detects that the liquid level of the mixed liquid in the storage tank reaches the high level, the first and second solenoid valves close, thereby blocking the water inlet pipe and the liquid inlet pipe, which facilitates the monitoring and control of the liquid level of the mixed liquid in the storage tank. 3. During the process of the water pump driving the mixed liquid in the storage tank to be transported to the spray pipe through the delivery pipe, part of the mixed liquid is transported to the storage tank through the installation pipe and the fixed pipe. At this time, the high-speed mixed liquid flowing out of the end of the fixed pipe mixes with the mixed liquid in the storage tank and mixes and stirs the finishing liquid and demineralized water transported to the storage tank, which facilitates the mixing of the replenished finishing liquid and demineralized water and improves work efficiency.

[0030] The present application will be further described in detail below with reference to the accompanying drawings.

[0031] This application discloses a spray system for galvanized finishing machines. Example 1

[0032] Reference Figure 1 and Figure 2 The optical finishing machine includes a frame 1 and horizontal rollers 11 rotatably connected to the frame 1 and arranged sequentially in the vertical direction. In this embodiment, two rollers are used, and a first motor (not shown in the figure) is mounted on the frame 1, corresponding one-to-one with each roller 11 and driving the rollers 11 to rotate. (Refer to...) Figure 1 , Figure 2 and Figure 3A galvanizing finishing machine spraying system includes horizontal spray pipes 2 fixedly connected to one side of the frame 1 in the vertical direction and corresponding one-to-one with the rollers 11. The spray pipes 2 are all higher than the rotation axis of the corresponding rollers 11, and multiple nozzles 21 that face the rollers 11 and are inclined downward are fixedly connected to the side of the spray pipes 2 near the rollers 11.

[0033] Reference Figure 3 and Figure 4 On the side of the frame 1 away from the spray pipe 2, there is a storage tank 3 containing a mixture of finishing liquid and demineralizing water. Two horizontal stabilizing pipes 31 parallel to the length direction of the roller body 11 are inserted and fixedly connected to one side of the storage tank 3. A water pump 311 is installed on each of the stabilizing pipes 31. The end of the stabilizing pipe 31 away from the storage tank 3 is fixedly connected and connected to a horizontal conveying pipe 32 facing the frame 1. The end of the conveying pipe 32 away from the stabilizing pipe 31 is bent upward to vertical and fixedly connected to the frame 1. The end of the spray pipe 2 near the conveying pipe 32 is fixedly connected and connected to the bent end of the conveying pipe 32.

[0034] Reference Figure 4 An opening 33 is located on the upper side of the storage tank 3, away from the frame 1. A horizontal mounting platform 34 is fixedly connected to the side of the storage tank 3 near the stabilizing pipe 31, located on the side of the storage tank 3 away from the frame 1. A horizontal storage tank 4 containing polishing liquid is mounted on the mounting platform 34. An inlet pipe 41 is fixedly connected and communicated to the end of the storage tank 4 away from the frame 1. The end of the inlet pipe 41 away from the storage tank 4 is inserted into the storage tank 3.

[0035] Reference Figure 3 and Figure 4 The storage tank 3 is provided with an inlet pipe 5 on the side away from the storage tank 4, which is located near the frame 1 and is used to transport demineralized water. The upper end of the inlet pipe 5 is bent to the horizontal side away from the frame 1 and is fixedly connected to a horizontal water supply pipe 51 facing the storage tank 3. The end of the water supply pipe 51 is inserted into the storage tank 3 and bent downward. The storage tank 3 is provided with an automatic dispensing component 6 for controlling the entry of finishing liquid and demineralized water into the storage tank 3. Both the water supply pipe 51 and the liquid inlet pipe 41 are equipped with a manual valve 42 to control the flow rate of the pipeline.

[0036] The automatic dispensing component 6 drives the water supply pipe 51 and the liquid inlet pipe 41 to transport the demineralized water in the water inlet pipe 5 and the finishing liquid in the storage tank 4 to the storage tank 3 for mixing. The water pump 311 transports the mixed liquid through the stabilizing pipe 31 and the conveying pipe 32 to each spray pipe 2, and sprays it onto the corresponding roller 11 through the nozzle 21, which facilitates the cleaning of the roller 11 and reduces the possibility of manually observing the amount of mixed liquid in the storage tank 3.

[0037] The flow rate of the water inlet pipe 5 and the liquid inlet pipe 41 can be controlled by the hand valve 42, which facilitates the control of the ratio of finishing liquid and demineralizing water entering the storage tank 3. The stabilizing pipe 31 and the water pump 311 are set in two sets. When one set is damaged, the mixed liquid is pumped to the conveying pipe 32 through the other set, which facilitates the repair of the damaged set and does not affect the cleaning of the roller body 11.

[0038] Reference Figure 4 The automatic dispensing component 6 includes a first solenoid valve 61 installed on the inlet pipe 41, a second solenoid valve 62 installed at the bent end of the inlet pipe 5, and a monitoring device for monitoring the liquid level of the mixture is provided in the storage tank 3. In this embodiment, the device is a liquid level sensor 63 installed in the storage tank 3.

[0039] The liquid level sensor 63 monitors the liquid level of the mixed liquid in the storage tank 3. When the liquid level of the mixed liquid in the storage tank 3 is low, the first solenoid valve 61 and the second solenoid valve 62 are opened. At this time, the water inlet pipe 5 delivers the demineralized water to the storage tank 3, and the liquid inlet pipe 41 delivers the finishing liquid to the storage tank 3, so as to facilitate the mixing of the finishing liquid and the demineralized water. When the liquid level sensor 63 detects that the liquid level of the mixed liquid in the storage tank 3 has reached the high level, the first solenoid valve 61 and the second solenoid valve 62 are closed, thereby blocking the water inlet pipe 5 and the liquid inlet pipe 41, so as to facilitate the monitoring and control of the liquid level of the mixed liquid in the storage tank 3.

[0040] Reference Figure 3 and Figure 4 A vertical mounting pipe 321 is fixedly connected to the upper side of the conveying pipe 32 near the stabilizing pipe 31. The upper end of the mounting pipe 321 is bent to a horizontal position away from the conveying pipe 32. The bent end of the mounting pipe 321 is located on the side of the storage box 3 near the frame 1 and is fixedly connected to and communicates with a horizontal fixing pipe 322 facing the storage box 3. The fixing pipe 322 is located on the upper side of the storage box 3, and the end of the fixing pipe 322 away from the frame 1 is bent downward and inserted into the storage box 3.

[0041] A vertical connecting pipe 52 is fixedly connected to the upper side of the bent end of the water inlet pipe 5. The upper end of the connecting pipe 52 is bent to a horizontal position near the upper opening 33 of the storage tank 3. A fixing rod (not shown in the figure) is provided at the opening 33 on the upper side of the storage tank 3, with its end fixedly connected to the upper side of the storage tank 3. The bent end of the connecting pipe 52 is bent towards the stabilizing pipe 31 and overlaps the upper side of the fixing rod. The end of the connecting pipe 52 near the stabilizing pipe 31 is located directly above the opening 33 and is equipped with a spiral nozzle 5321 facing the inside of the storage tank 3.

[0042] During the process of pump 311 driving the mixed liquid in storage tank 3 to be transported to spray pipe 2 through conveying pipe 32, part of the mixed liquid is transported to storage tank 3 through installation pipe 321 and fixed pipe 322. At this time, the high-speed mixed liquid flowing out from the end of fixed pipe 322 mixes with the mixed liquid in storage tank 3 and mixes and stirs the finishing liquid and demineralized water transported to storage tank 3, so as to facilitate the mixing of replenished finishing liquid and demineralized water.

[0043] During the process of demineralizing water being transported to storage tank 3 via inlet pipe 5, part of the demineralizing water is transported to spiral nozzle 5321 via connecting pipe 52 and sprayed out. At this time, the high-speed demineralizing water sprayed into storage tank 3 defoams the foam generated by mixing in storage tank 3, reducing the possibility of foam continuously rising and overflowing from the top of storage tank 3.

[0044] The implementation principle of Example 1 is as follows: When the liquid level of the mixture in the storage tank 3 is low, the first solenoid valve 61 and the second solenoid valve 62 are opened. At this time, the water inlet pipe 5 delivers the demineralized water to the storage tank 3, and the liquid inlet pipe 41 delivers the finishing liquid to the storage tank 3, so as to facilitate the mixing of the finishing liquid and the demineralized water. When the liquid level sensor 63 detects that the liquid level of the mixture in the storage tank 3 has reached the high level, the first solenoid valve 61 and the second solenoid valve 62 are closed, thereby blocking the water inlet pipe 5 and the liquid inlet pipe 41, so as to facilitate the monitoring and control of the liquid level of the mixture in the storage tank 3. Example 2

[0045] Reference Figure 5 The difference between this embodiment and embodiment 1 is that two horizontal air knives 7 are installed on the side of the frame 1 near the spray pipe 2, which are respectively corresponding to the roller 11 and arranged along the length of the roller 11. The air knives 7 are located on the lower side of the corresponding spray pipe 2 and higher than the rotation axis of the corresponding roller 11, and the air nozzles of the air knives 7 near the corresponding roller 11 are tilted downward.

[0046] Reference Figure 5 and Figure 6 A sponge 8 is provided on one side of the roller body 11 that is close to each other. The sponge 8 moves along the length of the roller body 11 and can contact both sides of the roller body 11 that are close to each other. The frame 1 is provided with a driving component 81 for moving the sponge 8. The driving component 81 includes a snap-fit ​​plate 811 that is disposed opposite to both sides of the sponge 8. The line connecting the snap-fit ​​plates 811 is perpendicular to the length of the roller body 11. Both sides of the sponge 8 are snapped into the corresponding snap-fit ​​plate 811. A horizontal sliding rod 812 is fixedly connected to the side of the snap-fit ​​plate 811 that is far apart from each other. A horizontal slide rail 813 that is fixedly connected to both sides of the frame 1 and is disposed along the length of the roller body 11. The slide rail 813 corresponds one-to-one with the sliding rod 812, and the ends of the sliding rods 812 that are far apart from each other are inserted into the corresponding slide rail 813 and slidably connected to the slide rail 813.

[0047] Each slide rail 813 is rotatably connected to a horizontal lead screw 814 arranged along the length of the slide rail 813. Each lead screw 814 passes through the end of the corresponding sliding rod 812 and is threadedly connected to the sliding rod 812. The same end of each lead screw 814 passes through the side wall of the frame 1 and is rotatably connected to the frame 1. A second motor 815 is installed at one end of each lead screw 814 that passes through the frame 1 and is fixedly connected to the frame 1.

[0048] The implementation principle of Example 2 is as follows: After the spray pipe 2 cleans the roller 11 through the nozzle 21, the air knife 7 blows the rotating roller 11 to remove the residual mixture on the roller 11. After the air knife 7 finishes blowing, the second motor 815 drives the sponge 8 to move along the length direction of the slide rail 813 through the lead screw 814, the sliding rod 812 and the snap plate 811 to further wipe away the residual mixture on the surface of the roller 11, reducing the possibility of the mixture adhering to the surface of the roller 11 and forming impurity particles.

[0049] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
