Description

Technical Field

[0001] The utility model relates to the technical field of mechanical processing equipment, in particular to a device for removing oxide scale from the edge of a strip steel. Background Art

[0002] Currently, stainless steel manufacturers remove scale from the edges of hot-rolled strip during the continuous annealing and pickling process. A common method for removing scale is side-blasting with a shot blasting machine. This method uses a high-speed rotating impeller to project steel shot onto the strip edge, striking the scale at high speed, breaking it and removing it.

[0003] However, this method has some significant drawbacks. Due to the angle of the shot blasting head during side-throwing, the machine is prone to jamming during operation, resulting in frequent equipment failures, high spare parts consumption, and high maintenance costs. Furthermore, this method is ineffective in removing oxide scale from the edges of the strip. Utility Model Content

[0004] In view of this, the present application aims to at least partially address the problems in the related art. The present application provides a device for removing oxide scale from the edges of steel strips, which can effectively remove oxide scale from the edges of steel strips. The device comprises a water supply mechanism, a high-pressure power mechanism, and a flushing mechanism; the output end of the water supply mechanism is connected to the input end of the high-pressure power mechanism; the output end of the high-pressure power mechanism is connected to the input end of the flushing mechanism; and the output end of the flushing mechanism is disposed on the side of the cleaning section.

[0005] Specifically, the water in the water supply mechanism is processed by the high-pressure power mechanism to become high-pressure water, which is then used to impact the oxide scale on the edge of the steel strip. The impact force and shear force of the high-pressure water are used to cause the oxide scale to fall off the edge of the steel strip. The present application sets the output end of the flushing mechanism on the side of the cleaning section, and uses high-pressure flushing to perform high-pressure impact on the oxide scale on the edge of the steel strip in the cleaning section, thereby effectively removing the oxide scale. Compared with the method of using shot blasting technology to remove oxide scale on the edge, the present application significantly reduces equipment maintenance costs, has a good oxide scale removal effect, and does not have the problem of steel shots getting stuck.

[0006] In a preferred technical solution of the present invention, the water supply mechanism includes: a water tank and a filter; the input end of the filter is connected to the output end of the water tank; the output end of the filter is connected to the input end of the high-pressure power mechanism.

[0007] Specifically, a filter layer is provided in the water tank, which is made of wire mesh with different mesh sizes to filter out particulate impurities. A water supply switch is provided under the water tank, and the filter is provided outside the water tank and connected to the water tank. The filter consists of two parts, the upper part is called the "filter cover" and the lower part is called the "filter cartridge". The filter cover is the inlet and outlet channel for compressed air. The filter element is suspended and fixed on the filter cover to filter impurities in the water. The filter cartridge restricts the compressed air to flow within the range of the filter housing and in the specified direction, while accepting the filtered water. When the device is working, turn on the water supply switch, and the water in the water tank flows into the filter and then enters the high-pressure power mechanism for pressure boosting. The combination of the filter layer and the filter can effectively filter out impurities in the water, protect the normal operation of related equipment in the workflow, avoid damage to the power mechanism and flushing mechanism due to blockage by impurities, and ensure the normal operation of the equipment.

[0008] In a preferred technical solution of the present invention, the high-pressure power mechanism includes: a high-pressure pump and an electric motor; the input end of the high-pressure pump is connected to the output end of the water supply mechanism; the output end of the high-pressure pump is connected to the input end of the flushing mechanism; the return end of the high-pressure pump is connected to the return end of the flushing mechanism; and the electric motor is electrically connected to the high-pressure pump.

[0009] The electric motor drives the high-pressure pump, which compresses the water, increasing its velocity and pressure, transforming ordinary water into high-pressure water. The powerful impact of the high-pressure water jet quickly strips and removes scale from steel edges, achieving not only rapid but also effective scale removal. The high-pressure pump and electric motor are connected via a coupling. The bell-shaped housing on the coupling ensures coaxiality between the motor and pump shafts, providing safety protection for both the pump and motor. In practice, the electric motor can be electrically connected to a distribution box to meet power requirements.

[0010] In a preferred technical solution of the present invention, the high-pressure power mechanism further includes: a safety valve; the input end of the safety valve is connected to the safety valve port of the high-pressure pump; and the output end of the safety valve is connected to the water supply mechanism.

[0011] The safety valve can quickly respond to pressure changes within the system, opening or closing in a timely manner to maintain stable pressure within the system. When the pressure within the system exceeds the set value of the safety valve, the safety valve automatically opens, releasing excess water in the pipeline, preventing equipment damage or casualties caused by overpressure. Specifically, the output end of the safety valve can be connected to the output end of the water tank or filter, which can quickly discharge excess water pressure. When the pressure of the high-pressure pump exceeds the predetermined value, the safety valve opens, and the water in the high-pressure pump flows into the safety valve and finally into the output end of the water tank or filter, thereby relieving pressure and preventing safety accidents.

[0012] In a preferred technical solution of the present invention, the high-pressure power mechanism further includes: a booster pump; the input end of the booster pump is connected to the output end of the water supply mechanism; the output end of the booster pump is connected to the input end of the high-pressure pump.

[0013] The main function of a booster pump is to increase water pressure. It is usually used in situations where domestic or industrial water pressure is insufficient. A high-pressure pump is usually used in industrial applications that require higher pressure. Using a booster pump in combination with a high-pressure pump can combine the advantages of both, improve the flexibility and applicability of the device, ensure that it can provide stable and efficient water pressure and flow, and can effectively remove oxide scale from the edges of strip steel.

[0014] In a preferred technical solution of the present invention, the high-pressure power mechanism further includes: an accumulator; the input end of the accumulator is connected to the output end of the high-pressure pump; and the output end of the accumulator is connected to the input end of the flushing mechanism.

[0015] The accumulator can convert the energy in the system into compression energy or potential energy at the appropriate time and store it. When the system needs energy, it converts the compression energy or potential energy into hydraulic or pneumatic pressure and releases it to replenish the system. When the system pressure increases instantaneously, the accumulator can absorb this energy. When the system pressure drops, the gas in the accumulator expands, pushing the hydraulic oil back into the system, maintaining the system pressure and ensuring stable operation.

[0016] In a preferred technical solution of the present invention, a pressure gauge is connected between the output end of the high-pressure pump and the input end of the energy accumulator.

[0017] The pressure gauge installed between the high-pressure pump and the energy accumulator can monitor the pressure changes between the high-pressure pump and the energy accumulator in real time, ensuring that the system operates within the normal working range, helping to detect pressure anomalies in time and avoid equipment damage or system failure caused by excessively high or low pressure.

[0018] In a preferred technical solution of the present invention, the flushing mechanism also includes a pressure regulating valve; the input end of the pressure regulating valve is connected to the output end of the energy accumulator; the output end of the pressure regulating valve is connected to the input end of the flushing mechanism; and the return end of the pressure regulating valve is connected to the return end of the high-pressure pump.

[0019] A pressure-regulating valve regulates the pressure of fluids in a system, keeping it within a certain range. It typically consists of a valve core, valve seat, spring, and piston. When the pressure in the piping system exceeds the set value, the valve core moves downward, reducing the pressure. When the pressure in the piping system falls below the set value, the spring force pushes the valve core upward, increasing the pressure.

[0020] In a preferred technical solution of the present invention, the flushing mechanism includes at least two nozzles; the input end of the nozzle is connected to the output end of the high-pressure power mechanism; and at least two of the nozzles are respectively arranged on both sides of the cleaning section.

[0021] Specifically, two nozzles are provided, with slots opened on both sides of the cleaning section. Branch nozzle hoses are also provided to connect the nozzles to the slots on both sides. The water in the water supply mechanism is processed by the high-pressure power mechanism and becomes high-pressure water. This high-pressure water is then sprayed from the nozzles on both sides of the cleaning section onto the edges of the steel strip within the cleaning section. The high-pressure water impacts the oxide scale on the edges of the steel strip, achieving the effect of rapid oxide scale removal.

[0022] In a preferred technical solution of the present invention, it further includes an outer frame; the water supply mechanism, the high-pressure power mechanism and the flushing mechanism are arranged in the outer frame; M hanging rings are provided on the top of the outer frame; and M is an integer greater than 0.

[0023] The outer frame holds all components together, and a lifting ring is provided on the outer frame to facilitate installation, maintenance, and replacement of the entire unit. In practice, a manual valve can be installed within the outer frame. This valve is connected to the branch nozzle hose and the water supply end of the pressure regulating valve via a tee connector. The outlet of the branch nozzle hose is located on the outer frame, allowing easy access to the high-pressure water within the device to flush the oxide scale on the strip edges.

[0024] The above technical solution provided by the embodiment of the present application has the following advantages over the prior art: The present application provides a device for removing oxide scale from the edge of the strip steel, and the water in the water supply mechanism is processed by the high-pressure power mechanism to become high-pressure water, which is used to impact the oxide scale on the edge of the strip steel, and the impact force and shear force of the high-pressure water are used to make the oxide scale fall off the edge of the strip steel. The present application sets the output end of the flushing mechanism on the side of the cleaning section, and performs high-pressure impact on the oxide scale on the edge of the strip steel in the cleaning section by high-pressure flushing, thereby achieving effective removal of the oxide scale. Compared with the method of removing oxide scale from the edge by shot blasting technology, the present application significantly reduces the equipment maintenance cost, has a good oxide scale removal effect, and does not have the problem of steel shots getting stuck.

[0039] Specifically, the water in the water supply mechanism is processed by the high-pressure power mechanism to become high-pressure water, which is then used to impact the oxide scale on the edge of the steel strip. The impact force and shear force of the high-pressure water are used to cause the oxide scale to fall off the edge of the steel strip. The present application sets the output end of the flushing mechanism on the side of the cleaning section, and uses high-pressure flushing to perform high-pressure impact on the oxide scale on the edge of the steel strip in the cleaning section, thereby effectively removing the oxide scale.

The filter cartridge limits the compressed air to flow within the range of the filter 13 shell and in a specified direction, while receiving the filtered water. When the device is working, turn on the water supply switch, and the water in the water tank 11 flows into the filter 13 and then enters the high-pressure power mechanism for pressure boosting. The combination of the filter layer and the filter 13 can effectively filter out impurities in the water, protect the normal operation of related equipment in the workflow, avoid damage to the power mechanism and flushing mechanism due to blockage by impurities, and ensure the normal operation of the equipment.

[0042] Example 2

[0043] like Figures 1-4 As shown, this embodiment provides a device for removing oxide scale from the edge of a strip, comprising: a water supply mechanism, a high-pressure power mechanism and a flushing mechanism; the output end of the water supply mechanism is connected to the input end of the high-pressure power mechanism; the output end of the high-pressure power mechanism is connected to the input end of the flushing mechanism; the output end of the flushing mechanism is arranged on the side of the cleaning section.

[0044] Specifically, the water in the water supply mechanism is processed by the high-pressure power mechanism to become high-pressure water, which is then used to impact the oxide scale on the edge of the steel strip. The impact force and shear force of the high-pressure water are used to cause the oxide scale to fall off the edge of the steel strip. The present application sets the output end of the flushing mechanism on the side of the cleaning section, and uses high-pressure flushing to perform high-pressure impact on the oxide scale on the edge of the steel strip in the cleaning section, thereby effectively removing the oxide scale. Compared with the method of using shot blasting technology to remove oxide scale on the edge, the present application significantly reduces equipment maintenance costs, has a good oxide scale removal effect, and does not have the problem of steel shots getting stuck.

[0045] Preferably, the water supply mechanism includes: a water tank 11 and a filter 13; the input end of the filter 13 is connected to the output end of the water tank 11; the output end of the filter 13 is connected to the input end of the high-pressure power mechanism.

[0046] Specifically, a filter layer is provided in the water tank 11, which is made of wire mesh with different meshes to filter out particulate impurities. A water supply switch is provided below the water tank 11, and the filter 13 is provided outside the water tank 11 and is connected to the water tank 11.

[0047] Preferably, the high-pressure power mechanism includes: a high-pressure pump 23 and an electric motor 27; the input end of the high-pressure pump 23 is connected to the output end of the water supply mechanism; the output end of the high-pressure pump 23 is connected to the input end of the flushing mechanism; the return end of the high-pressure pump 23 is connected to the return end of the flushing mechanism; the electric motor 27 is electrically connected to the high-pressure pump 23.

[0048] The high-pressure pump 23 in this embodiment is a plunger pump, which has a simple structure, high reliability and easy maintenance. The motor 27 is a three-phase asynchronous motor. After the frequency of the three-phase asynchronous motor is set, it can drive the high-pressure pump 23 to compress the water, increase the speed and pressure of the water, and turn ordinary water into high-pressure water. The high-pressure water jet has a strong impact force and can quickly peel off and wash away the oxide scale on the edge of the steel. It is not only fast but also has a significant effect in removing oxide scale. The high-pressure pump 23 and the motor 27 are connected by a coupling. The bell-shaped cover 271 on the coupling is used to make the motor shaft coaxial with the high-pressure pump shaft, and at the same time has a safety protection effect on the high-pressure pump 23 and the motor 27. In practice, the motor 27 can be electrically connected to the distribution box 26 to meet the corresponding power demand.

[0049] The high-pressure power mechanism further includes: a safety valve; an input end of the safety valve is connected to the safety valve port 231 of the high-pressure pump 23; and an output end of the safety valve is connected to the water supply mechanism.

[0050] The safety valve can quickly respond to changes in pressure within the system and open or close in time to maintain stable pressure in the system. When the pressure in the system exceeds the set value of the safety valve, the safety valve will automatically open to release excess water in the pipeline to prevent equipment damage or casualties caused by overpressure. In this embodiment, the safety valve is a spring-loaded safety valve that can control the pressure in the pipeline system with high precision and has high reliability. The output end of the safety valve can be connected to the output end of the water tank 11 or the filter 13, and can quickly discharge excessive water pressure. When the pressure of the high-pressure pump 23 exceeds a predetermined value, the safety valve opens, and the water in the high-pressure pump 23 flows into the safety valve and finally flows into the output end of the water tank 11 or the filter 13, thereby playing a role in pressure relief and preventing the occurrence of safety accidents.

[0051] Preferably, the high-pressure power mechanism further includes: a booster pump 22 ; the input end of the booster pump 22 is connected to the output end of the water supply mechanism; the output end of the booster pump 22 is connected to the input end of the high-pressure pump 23 .

[0052] The primary function of booster pump 22 is to increase water pressure. It is typically used in situations where household or industrial water pressure is insufficient. High-pressure pump 23 is typically used in industrial applications requiring higher pressure. Combining booster pump 22 with high-pressure pump 23 combines the advantages of both, improving the flexibility and applicability of the device, ensuring stable and efficient water pressure and flow, and enabling efficient descaling of strip steel edges. Specifically, in this embodiment, booster pump 22 is a pneumatic liquid booster pump. Its specific structure includes a reversing valve, a gas piston, and a hydraulic plunger. The reversing valve controls the reciprocating motion of the gas piston, which in turn drives the hydraulic plunger to produce high-pressure liquid output.

[0053] Preferably, the high-pressure power mechanism further includes: an accumulator 25; the input end of the accumulator 25 is connected to the output end of the high-pressure pump 23; the output end of the accumulator 25 is connected to the input end of the flushing mechanism.

[0054] Accumulator 25 can convert system energy into compressed or potential energy at the appropriate time and store it. When the system needs energy, it converts the compressed or potential energy into hydraulic or pneumatic energy and releases it to replenish the system. When the system pressure increases instantaneously, it absorbs this energy. When the system pressure drops, the gas in accumulator 25 expands, pushing the hydraulic oil back into the system, maintaining the system pressure and ensuring stable operation. Specifically, in this embodiment, the accumulator is a waterjet accumulator, which can release a huge amount of energy in a very short time, providing a stable high-pressure water flow to achieve the purpose of cutting the oxide scale on the edge of the strip.

[0055] Preferably, a pressure gauge 24 is connected between the output end of the high-pressure pump 23 and the input end of the energy accumulator 25 .

[0056] The pressure gauge 24 is provided between the high-pressure pump 23 and the accumulator 25 to monitor the pressure changes between the high-pressure pump 23 and the accumulator 25 in real time, ensuring that the system operates within the normal operating range, helping to detect pressure anomalies in a timely manner, and avoiding equipment damage or system failure caused by excessively high or low pressure.

[0057] Preferably, the flushing mechanism further includes a pressure regulating valve 28; the input end of the pressure regulating valve 28 is connected to the output end of the accumulator 25; the output end of the pressure regulating valve 28 is connected to the input end of the flushing mechanism; the reflux end of the pressure regulating valve 28 is connected to the reflux end of the high-pressure pump 23.

[0058] Pressure-regulating valve 28 regulates the pressure of the fluid in the system, keeping it within a certain range. It typically consists of a valve core, valve seat, spring, piston, and other components. When the pressure in the pipeline system exceeds the set value, the valve core moves downward, reducing the pressure. When the pressure in the pipeline system falls below the set value, the spring force pushes the valve core upward, increasing the pressure. Pressure-regulating valve 28 in this embodiment is a manual pressure-regulating valve with a simple structure and easy operation. By turning the handle, the spiral rod rotates, changing the valve core pressure, thereby controlling the flow rate and achieving the purpose of pressure regulation.

Specifically, in this embodiment, booster pump 22 is a pneumatic liquid booster pump. Its specific structure includes a reversing valve, a gas piston, and a hydraulic plunger. The reversing valve controls the reciprocating motion of the gas piston, which in turn drives the hydraulic plunger to produce high-pressure liquid output.

[0070] Preferably, the high-pressure power mechanism further includes: an accumulator 25; the input end of the accumulator 25 is connected to the output end of the high-pressure pump 23; the output end of the accumulator 25 is connected to the input end of the flushing mechanism.

[0071] Accumulator 25 can convert system energy into compressed or potential energy at the appropriate time and store it. When the system needs energy, it converts the compressed or potential energy into hydraulic or pneumatic energy and releases it to replenish the system. When the system pressure increases instantaneously, it absorbs this energy. When the system pressure drops, the gas in accumulator 25 expands, pushing the hydraulic oil back into the system, maintaining the system pressure and ensuring stable operation. Specifically, in this embodiment, the accumulator is a waterjet accumulator, which can release a huge amount of energy in a very short time, providing a stable high-pressure water flow to achieve the purpose of cutting the oxide scale on the edge of the strip.

[0072] Preferably, a pressure gauge 24 is connected between the output end of the high-pressure pump 23 and the input end of the energy accumulator 25 .

[0073] The pressure gauge 24 is provided between the high-pressure pump 23 and the accumulator 25 to monitor the pressure changes between the high-pressure pump 23 and the accumulator 25 in real time, ensuring that the system operates within the normal operating range, helping to detect pressure anomalies in a timely manner, and avoiding equipment damage or system failure caused by excessively high or low pressure.

[0074] Preferably, the flushing mechanism further includes: a pressure regulating valve 28; the input end of the pressure regulating valve 28 is connected to the output end of the accumulator 25; the output end of the pressure regulating valve 28 is connected to the input end of the flushing mechanism; the reflux end of the pressure regulating valve 28 is connected to the reflux end of the high-pressure pump 23.

[0075] Pressure-regulating valve 28 regulates the pressure of the fluid in the system, keeping it within a certain range. It typically consists of a valve core, valve seat, spring, piston, and other components. When the pressure in the pipeline system exceeds the set value, the valve core moves downward, reducing the pressure. When the pressure in the pipeline system falls below the set value, the spring force pushes the valve core upward, increasing the pressure. Pressure-regulating valve 28 in this embodiment is a manual pressure-regulating valve with a simple structure and easy operation. By turning the handle, the spiral rod rotates, changing the valve core pressure, thereby controlling the flow rate and achieving the purpose of pressure regulation.

[0076] Preferably, the flushing mechanism includes at least two nozzles 31; the input end of the nozzle 31 is connected to the output end of the high-pressure power mechanism; and at least two of the nozzles 31 are respectively arranged on both sides of the cleaning section.

[0077] Specifically, two nozzles 31 are provided, with slots provided on both sides of the cleaning section. Branch nozzle hoses 32 are provided to connect the slots on both sides of the nozzles 31. The specific workflow of this embodiment is as follows: the water in the water tank 11 is filtered through the filter screen and the filter, then flows into the booster pump 22 for boosting, then flows into the high-pressure pump 23 for pressurization, and then flows through the pressure gauge 24, the accumulator 25, and the pressure regulating valve 28, and finally flows into the nozzles 31 on both sides of the cleaning section. The nozzles 31 spray high-pressure water to cut and rinse the oxide scale on the edges of the steel strip. The return water from the pressure regulating valve 28 flows into the high-pressure pump 23, and the water from the safety valve flows into the output end of the water tank 11 or the filter 13.

[0078] Preferably, it further includes an outer frame 41; the water supply mechanism, the high-pressure power mechanism and the flushing mechanism are arranged in the outer frame 41; M hanging rings 42 are provided on the top of the outer frame 41; and M is an integer greater than 0.

[0079] The components are assembled together using an outer frame 41, and a lifting ring 42 is provided on the outer frame 41 to facilitate installation, maintenance, and replacement of the entire equipment. In practice, a manual valve 33 can be installed within the outer frame 41. The manual valve 33 is connected to the branch nozzle hose 32 and the output end of the pressure regulating valve 28 via a three-way connector 331. The outlet 34 of the branch nozzle hose 32 is located on the outer frame 41, making it easy to use the high-pressure water within the device to flush the oxide scale on the edges of the strip.
