Description

Technical Field

[0001] The utility model relates to the technical field of cleaning inside a roll, and particularly relates to a device for cleaning and descaling a roll core water tank. Background Art

[0002] Scaling in the roll core water tank of a casting roll is a common problem. Currently, the methods to solve the scaling in the roll core water tank of a casting roll include replacing the roll sleeve. During the process of replacing the roll sleeve, manual cleaning and turning processing methods are used for cleaning. In addition, circulating water water treatment is used to inhibit scaling in the roll sleeve roll core water tank. The method of replacing the roll sleeve requires removing the sleeve and manual cleaning to solve the scaling, with relatively high cost. Moreover, the roll sleeve is processed by hot-fitting, and each time the sleeve is removed and installed, it cannot be achieved by itself and must rely on professional tooling and equipment, which is time-consuming and laborious. Using the method of treating the circulating water quality to inhibit the generation of scaling, although it seems to have a lower cost, the problem of water scale cannot be completely solved, and strict management of the use of circulating water is required, increasing the management cost, only delaying the time of scaling and alleviating the scaling condition. Content of the Utility Model

[0003] Technical Problem to be Solved by the Utility Model

[0004] Aiming at the technical problem that it is difficult to solve the scaling in the roll core water tank of the existing casting roll at low cost and efficiently, the utility model provides a device for cleaning and descaling a roll core water tank, which can efficiently remove the scaling in the roll core water tank of the casting roll and has a relatively low cost.

[0005] Technical Solution

[0006] To solve the above problems, the technical solution provided by the utility model is as follows:

[0007] A device for cleaning and descaling a roll core water tank includes a descaling liquid part, which is internally provided with a descaling liquid. The descaling liquid part is provided with an outlet and an inlet, and the outlet and the inlet are connected to the roll core water tank through valves and pipelines; a clean water part, which is internally provided with clean water. The clean water part is provided with an outlet and an inlet, and the outlet and the inlet are connected to the roll core water tank through valves and pipelines; a water jacket, which is sleeved on the notch of the roll core water tank; a driving mechanism, which is installed on the pipeline.

[0008] Descaling Liquid Part:

[0009] It is internally filled with a descaling liquid, which usually has certain chemical properties and can dissolve or soften deposits such as water scale and rust.

[0010] It is provided with an outlet and an inlet, and is connected to the roll core water tank through valves and pipelines, so that the descaling liquid can be circulated by controlling the valves to ensure that it evenly covers and acts on the surface of the water tank.

[0011] Clean Water Part:

[0012] It is filled with clean water, which is used to rinse off the remaining descaling liquid and dissolved scale after the descaling process.

[0013] It also has an outlet and an inlet, which are connected to the roll core water tank through valves and pipelines, so that clean water can be introduced for rinsing when needed.

[0014] Water jacket:

[0015] It is sleeved on the notch of the roll core water tank, which may be for sealing the water tank to prevent the leakage of descaling liquid or water during the cleaning process, and may also play a role in heat preservation or isolating the external environment.

[0016] Drive mechanism:

[0017] It is installed on the pipeline and used to provide power to enable the descaling liquid and clean water to circulate in the pipeline for the purpose of cleaning. This may be a pump or other type of fluid drive device.

[0018] Optionally, it also includes a mobile trolley, and both the descaling liquid part and the clean water part are installed on the mobile trolley.

[0019] Enhanced flexibility:

[0020] The mobile trolley allows the operator to easily move the descaling liquid part and the clean water part from one position to another without a complex reinstallation process, which is very beneficial for the maintenance of large factories or multiple production lines.

[0021] Space saving:

[0022] When not in use, the entire system can be moved to the storage area or a space that does not occupy the production area, thereby optimizing the workshop layout and improving space utilization.

[0023] Convenience:

[0024] The operator can move and position the system alone or with a small number of people without relying on additional lifting equipment, improving work efficiency.

[0025] Integrated design:

[0026] Integrating the descaling liquid part and the clean water part on one platform simplifies the operation process and reduces the chaos and errors that may be caused by the dispersion of different components.

[0027] Quick response:

[0028] When an emergency cleaning is required in a specific area or for a specific equipment, the mobile trolley can enable the operator to quickly reach the scene and solve the problem in a timely manner.

[0029] Easy maintenance:

[0030] All components are concentrated on a trolley, which facilitates daily inspection and maintenance and also makes it convenient for regular maintenance and repair of the entire system.

[0031] Optionally, the bottom end of the mobile trolley is provided with moving wheels.

[0032] The mobile trolley can effectively move in different working environments, ensuring that the descaling and cleaning device can be efficiently and safely deployed to where it is needed.

[0033] Optionally, the inlet of the descaling liquid section and the inlet of the purified water section are connected through an inlet pipeline, and the outlet of the descaling liquid section and the outlet of the purified water section are connected through an outlet pipeline. Both the inlet pipeline and the outlet pipeline are connected to the roller core water tank and are controlled by valves.

[0034] Valve control:

[0035] Valves are used to control the flow direction and on / off state of fluids, ensuring that the descaling liquid and purified water enter or leave the water tank at the appropriate time. This may include solenoid valves, manual valves, or other types of automatic control valves.

[0036] Sequential operation:

[0037] This design supports sequential operation of two functional modules. First, the descaling liquid can be guided into the water tank for cleaning through the valve, then the valve of the descaling liquid section is closed, the valve of the purified water section is opened, and the water tank is rinsed with purified water to remove residual scale and descaling liquid.

[0038] Cost savings:

[0039] The shared pipeline reduces the number of pipelines required, lowering the material cost and installation cost. At the same time, due to the reduction of pipeline joints and fittings, potential leakage points may also be reduced, improving the reliability and safety of the system.

[0040] Simplified operation:

[0041] By simplifying the pipeline and valve configuration, operators can more easily understand and operate the entire system, reducing the risk of misoperation.

[0042] Easy to maintain:

[0043] The reduced number of pipelines and valves means fewer points to be concerned about during maintenance and inspection, thereby reducing the maintenance cost and downtime.

[0044] Optionally, a first branch return valve is provided at the inlet of the descaling liquid section, a branch inlet valve is provided at the outlet of the descaling liquid section, a second branch return valve is provided at the inlet of the purified water section, a water inlet valve is provided at the outlet of the purified water section, a main return valve is provided on the inlet pipeline, a main inlet valve is provided on the outlet pipeline, and a bypass pipeline and a bypass valve are provided between the inlet pipeline and the outlet pipeline.

[0045] First branch return valve and second branch return valve:

[0046] These valves are located at the inlets of the descaling liquid section and the purified water section, respectively controlling whether the descaling liquid and the purified water return from their respective containers to the inlet pipeline. When closed, the liquid can only flow out of the container; when open, the liquid can flow back, for example, during the preparation or end stage of the cleaning cycle for liquid circulation or evacuation.

[0047] Branch inlet valve and water inlet valve:

[0048] The branch inlet valve is located at the outlet of the descaling liquid section, controlling the entry of the descaling liquid into the roll core water tank; the water inlet valve is located at the outlet of the purified water section, controlling the entry of the purified water into the water tank. These valves ensure that the liquid is fed into the water tank at the appropriate time.

[0049] Main return valve and main inlet valve:

[0050] The main return valve is located on the inlet pipeline, and the main inlet valve is located on the outlet pipeline. These two valves control the liquid flow between the entire system and the roll core water tank. During the cleaning process, the main inlet valve is opened to allow the liquid to flow into the water tank, and the main return valve is opened to allow the liquid to flow back from the water tank to the system.

[0051] Bypass pipeline and bypass valve:

[0052] The bypass pipeline connects the inlet pipeline and the outlet pipeline, and the bypass valve controls the opening and closing of the bypass pipeline. The existence of the bypass pipeline provides another liquid flow path, which can be used to circulate the liquid without passing through the roll core water tank, such as when preheating the descaling liquid or purified water, testing the system pressure, or cleaning the system.

[0053] Optionally, filters are provided at the pipe openings of the inlet pipeline for the descaling liquid section and the purified water section.

[0054] Preventing impurity entry:

[0055] The filters can intercept solid particles, suspended substances, or microorganisms that may exist in the descaling liquid or purified water, preventing these impurities from entering the roll core water tank and affecting the cleaning effect or causing blockage of the water tank.

[0056] Protecting system components:

[0057] Clean liquid can reduce the wear of system components such as pipelines, valves and pumps, extend the service life of equipment, and reduce maintenance costs.

[0058] Ensure the efficiency of chemical reactions:

[0059] For the descaling liquid, the filter can ensure that there are no impurities in the liquid interfering with the chemical reaction, and guarantee the maximization of the descaling effect.

[0060] Maintain water quality standards:

[0061] For the water purification section, the filter helps to maintain the purity of water, ensure that the descaling liquid and scale residues can be completely removed during the flushing stage, and avoid secondary pollution.

[0062] Optionally, the valve is a corrosion-resistant ball valve.

[0063] Corrosion resistance:

[0064] Corrosion-resistant ball valves are usually made of special materials such as stainless steel, nickel alloy, Hastelloy or plastics, etc. These materials can resist the corrosion of descaling liquid and other chemical media, and extend the service life of the valve.

[0065] Sealing performance:

[0066] The ball valve has good sealing performance. Relying on the O-ring or other elastic materials on the ball to closely contact the valve seat, it can maintain good sealing effect even under high pressure and prevent leakage.

[0067] Quick opening and closing:

[0068] The opening and closing of the ball valve only need to rotate 90 degrees. The operation is quick and simple, and it is suitable for cleaning systems that need to be switched frequently.

[0069] Low torque operation:

[0070] Compared with other types of valves, the ball valve requires less opening and closing torque, even under high pressure, which makes the operation easier.

[0071] Full bore design:

[0072] The bore diameter of the ball valve is usually the same as the pipeline diameter, which means that the resistance of the fluid passing through the valve is the smallest, and it is beneficial to maintain a higher flow rate and flow.

[0073] Easy maintenance:

[0074] The structure of the ball valve is relatively simple, easy to disassemble and maintain, and it is relatively easy to replace the O-ring or other seals.

[0075] Two-way fluid control:

[0076] Most ball valves allow bidirectional fluid flow, which can be very important in certain cleaning cycles, such as when reverse flushing or circulating descaling fluid is required.

[0077] Optionally, the water jacket is provided with a water inlet cylinder and a water outlet cylinder. The water outlet cylinder surrounds the water inlet cylinder. The water inlet of the water inlet cylinder is located at the end, and the water outlet of the water outlet cylinder is located on the circumference.

[0078] The water inlet cylinder and the water outlet cylinder each have independent channels, which means that fresh descaling fluid and clean water can be directly injected from one end of the water inlet cylinder, while the water that has undergone the cleaning process is discharged from the circumference of the water outlet cylinder. This design avoids the mixing of new and old liquids and ensures the maximization of the cleaning effect.

[0079] Optionally, the descaling fluid section is provided with a descaling fluid tank, the clean water section is provided with a clean water tank, and the descaling fluid tank is provided with a tank cover.

[0080] Storage function:

[0081] The descaling fluid tank and the clean water tank are mainly used to store the corresponding liquids, namely descaling fluid and clean water, to ensure that the system has sufficient liquid supply for cleaning and flushing operations.

[0082] Sealing property:

[0083] The presence of the tank cover ensures the sealing property of the descaling fluid tank, prevents external dust and impurities from entering the liquid, and can also reduce liquid evaporation and maintain the stability of the liquid concentration.

[0084] Safety protection:

[0085] The closed tank cover can prevent operators from accidentally contacting the descaling fluid, especially when the descaling fluid is corrosive or toxic, which is particularly important.

[0086] Convenient for filling and maintenance:

[0087] The tank cover is usually openable, which makes it simple to add descaling fluid or clean water, and is also convenient for regularly checking and cleaning the inside of the tank to ensure the liquid quality and system hygiene.

[0088] Beneficial effects

[0089] Adopting the technical solution provided by the present utility model, compared with the prior art, it has the following beneficial effects:

[0090] The technical solution provided by the present utility model sets up a circulating descaling fluid and clean water cleaning roll core water tank, which can efficiently remove the scale in the roll core water tank of the casting and rolling roll, and has a low cost because it can reuse the descaling fluid and does not require a complex mechanical structure.

[0095] To further understand the content of the present invention, the present invention will be described in detail in combination with the accompanying drawings and embodiments.

[0096] Embodiment

[0097] Combined with the attached Figure 1 , a roll core water tank cleaning and descaling device includes a descaling liquid part 5, which is internally provided with descaling liquid. The descaling liquid part 5 is provided with an outlet and an inlet, and the outlet and the inlet are connected to the roll core water tank through valves and pipelines. The descaling liquid is an acid liquid, and the cleaning acid liquid may contain the following components: Inorganic acids: one or more of sulfuric acid (H2SO4), hydrochloric acid (HCl), nitric acid (HNO3), hydrofluoric acid (HF), and phosphoric acid (H3PO4). Organic acids: one or more of citric acid (C6H8O7), oxalic acid (H2C2O4), and acetic acid (CH3COOH). Complexing agents: ethylenediaminetetraacetic acid (EDTA): tartaric acid: Surfactants: such as sodium alkylbenzene sulfonate, sodium lauryl sulfate, etc., which are used to reduce the surface tension of water and enhance the permeability and detergency of the cleaning liquid. Inhibitors: added to the acid liquid to reduce the corrosion of the acid liquid on the metal matrix and protect the matrix material from damage. Auxiliaries: including pH regulators, stabilizers, solubilizers, etc., which are used to improve the performance of the cleaning liquid and ensure the efficiency and safety of the cleaning process.

[0098] It also includes a clean water part 7, which is internally provided with clean water. The clean water part 7 is provided with an outlet and an inlet, and the outlet and the inlet are connected to the roll core water tank through valves and pipelines;

[0099] The descaling liquid part 5 is provided with a descaling liquid tank, and the purified water part 7 is provided with a purified water tank. A liquid tank cover 13 is provided on the descaling liquid tank. Through the descaling liquid tank and the purified water tank, the cleaning system can not only effectively store and manage the cleaning liquid, but also ensure the safety of operation and the long-term reliability of the system. To determine the cleaning effect of the water tank, the rolls need to be loaded into the equipment, and the cleaning effect can be judged through rolling and temperature measurement. The descaling liquid tank and the purified water tank are set to be transparent, and the cleaning result can also be judged from the clarity of the cleaning acid liquid.

[0100] It also includes a water jacket 3 sleeved on the notch of the roll core water tank. In this embodiment, the roll where the roll core is located is a casting roll 2. A roll stand 1 is provided under the casting roll 2. The roll stand 1 is mainly used to support the casting roll 2 to ensure that it can work stably under the conditions of high temperature, heavy load and high-speed operation. The structural strength and stability of the roll stand 1 are crucial for the safety and efficiency of the casting process.

[0101] It also includes a driving mechanism installed on the pipeline. The driving mechanism is a centrifugal pump 4 and a motor 9. The motor 9 drives the blades of the centrifugal pump 4 to rotate, generating suction for the descaling liquid and the purified water and pumping them into the roll core water tank. A pressure gauge 10 is provided on the pipeline, which can display the pressure level in the pipeline in real time, helping the operator understand the current state of the system and ensuring that the pressure is within a safe range. Excessive pressure may cause damage to the pipeline or equipment, and even lead to safety accidents. By continuously monitoring the pressure, measures can be taken in time, such as adjusting the valve opening or starting the pressure relief device, to avoid overpressure. Different cleaning stages may require different pressure levels. For example, higher pressure may be required when using the descaling liquid to ensure that the liquid can effectively penetrate the scale layer. The data of the pressure gauge 10 can help the operator adjust the system parameters according to needs and optimize the cleaning effect. Abnormal pressure readings may indicate problems in the system, such as pipeline blockage, pump performance decline or valve failure. By analyzing the pressure changes, potential problems can be identified and solved more quickly. Regularly recording and comparing the pressure data can help the maintenance team evaluate the system health status, plan necessary maintenance or replace aging components, and extend the system life.

[0102] It also includes a mobile trolley 6, and both the descaling liquid part 5 and the purified water part 7 are installed on the mobile trolley 6. The bottom end of the mobile trolley 6 is provided with mobile wheels, and the mobile wheels are universal wheels.

[0103] Combined with the attached Figure 2 , the inlet of the descaling liquid part 5 and the inlet of the purified water part 7 are connected through an inlet pipeline, and the outlet of the descaling liquid part 5 and the outlet of the purified water part 7 are connected through an outlet pipeline. Both the inlet pipeline and the outlet pipeline are connected to the roll core water tank and are controlled by valves.

[0104] At the entrance of the descaling liquid section 5, there is a first branch return liquid valve 1204. At the exit of the descaling liquid section 5, there is a branch inlet liquid valve 1206. At the entrance of the purified water section 7, there is a second branch return liquid valve 1205. At the exit of the purified water section 7, there is an inlet water valve 1207. On the inlet pipeline, there is a total return liquid valve 1201. On the outlet pipeline, there is a total inlet liquid valve 1203. Between the inlet pipeline and the outlet pipeline, there is a bypass pipeline and a bypass valve 1202.

[0105] Cleaning stage: The branch inlet liquid valve 1206 and the total inlet liquid valve 1203 are opened to let the descaling liquid enter the water tank. The total return liquid valve 1201 is opened to allow the liquid to flow back, and the cleaning cycle starts.

[0106] Rinsing stage: The branch inlet liquid valve 1206 is closed, the inlet water valve 1207 and the total inlet liquid valve 1203 are opened, and the descaling liquid is replaced with purified water for rinsing.

[0107] Circulation or emptying: The branch return liquid valve is used to circulate or empty the liquid in their respective containers to prepare for the next stage.

[0108] System maintenance or testing: The bypass valve 1202 is opened, and the system is circulated through the bypass pipeline. It does not involve the roll core water tank and can be used for maintenance, pressure testing or temperature adjustment.

[0109] At the pipe orifices of the descaling liquid section 5 and the purified water section 7 on the inlet pipeline, there is a filter 11.

[0110] The valve is a corrosion-resistant ball valve 12.

[0111] Combined with the attached Figure 3 The water jacket 3 is provided with an inlet cylinder and an outlet cylinder. The outlet cylinder surrounds the circumferential side of the inlet cylinder. The water inlet of the inlet cylinder is located at the end, and the water outlet of the outlet cylinder is located on the circumferential side.

[0112] The working process is generally as follows:

[0113] First, the descaling liquid is pumped into the roll core water tank to soften or dissolve the scale through chemical action.

[0114] Then, through circulating flow, ensure that the descaling liquid is evenly distributed and fully acts on the entire surface of the water tank: First, close the bypass valve 1202 and the second branch return liquid valve 1205, start the motor 9, and the acid liquid enters the water jacket 3 to the roll core part through the inlet water valve 1207, the branch inlet liquid valve 1206, and the total inlet liquid valve 1203. The return liquid enters the acid liquid tank through the water jacket 3 through the total return liquid valve 1201 and the first branch return liquid valve 1204, so that the circulation cleaning and descaling can be carried out.

[0115] After that, rinse the water tank with clean water to flush out the dissolved scale and the residue of the descaling solution: When the pickling is completed, the bypass valve 1202, the first sub-return liquid valve 1204, and the sub-inlet liquid valve 1206 need to be closed. Use the pump to pump clean water into the roller water tank, and then return it to the clean water tank through the main return liquid valve 1201 and the second sub-return liquid valve 1205, so that the acid liquid or descaling agent in the roller can be cleaned;

[0116] Finally, drying treatment is also required to ensure that the water tank is completely dry to prevent the formation of new scale.

[0117] The above schematically describes the present invention and its implementation manners. This description is not restrictive, and only one of the implementation manners of the present invention is shown in the drawings. The actual structure is not limited thereto.
