Description

Technical Field

[0001] The present invention relates to the technical field of spray dust removal for rolling mills, and specifically, to a method and system for spray dust removal of rolling mills. Background Art

[0002] During wire rolling, iron oxide dust generated at high temperatures is prone to volatilize and diffuse, and floats in the workshop for a long time. This not only seriously affects human health, but also causes blockage of ventilation ducts and fouling on the motor housing, thereby increasing the motor temperature and reducing its load-bearing capacity, ultimately affecting the operation of the equipment.

[0003] In the prior art, the mainstream dust removal methods in rolling mill workshops mainly include mechanical ventilation physical dust removal and wet dust removal. The technological process of mechanical ventilation physical dust removal is: dust suction hood → pipeline → dust removal equipment → fan → chimney. The performance of the dust suction hood directly affects the dust suction efficiency, while the dust removal equipment determines the final dust removal effect. However, due to the fact that most dust removal equipment is retrofitted later, the workshop environment is complex and there are many pipelines, resulting in a relatively long distance between the dust suction hood and the billet, and some dust cannot be effectively absorbed and diffuses into the air. In addition, this method has problems such as high equipment cost, high energy consumption, high operating cost, and the need for regular maintenance. For wet dust removal, the spray dust removal device atomizes high-pressure water and uses water spray to capture dust in the air to achieve the purpose of dust removal. However, there are still the following drawbacks: poor atomization effect, low dust removal efficiency, large water consumption, high water consumption cost, and it is easy to cause a significant drop in the billet temperature and uneven temperature distribution, thereby affecting the rolling quality.

[0004] Therefore, there is an urgent need for a high-efficiency method for spray dust removal of rolling mills. Summary of the Invention

[0041] Embodiment 1

[0042] The following will describe each embodiment of the present invention in detail with reference to the accompanying drawings.

[0043] Figure 1 is a schematic flow diagram of a rolling mill spray dust removal device according to an embodiment of the present invention.

[0044] The present invention protects a rolling mill spray dust removal method, as Figure 1 shown, the method includes,

[0045] S110. Obtain the smoke volume data at the corresponding dust removal working position of the rolling mill by using the smoke concentration monitoring sensor at each dust removal working position.

[0046] S120. Adjust the nozzle position of the dust removal spray according to the obtained smoke volume data at each dust removal working position.

[0047] S130. Determine the required spray pressure according to the smoke volume data at the dust removal working position corresponding to the nozzle position.

[0048] S140. Control the water supply pressure by adjusting the rotation speed of the variable frequency pump according to the required spray pressure, and perform spray dust removal at the dust removal working position corresponding to the nozzle position.

[0049] As an improvement of this embodiment, controlling the water supply pressure by adjusting the rotation speed of the variable frequency pump according to the required spray pressure and performing spray dust removal at the dust removal working position corresponding to the nozzle position further includes the following steps.

[0050] S141. Detect the roll biting signal and the roll stripping signal by using the roll biting sensor and the roll stripping sensor at the dust removal working position; S142. When the roll biting sensor detects the roll biting signal, start the spray dust removal by controlling the water cut-off valve and the variable frequency pump; S143. When the roll stripping sensor detects the roll stripping signal, stop the spray dust removal by controlling the water cut-off valve and the variable frequency pump. Specifically, the start and stop of the spray dust removal are automatically controlled by using the roll biting and stripping sensors, reducing manual intervention and improving efficiency. The spray dust removal method of the rolling mill of the present invention is adjusted in real time according to the working conditions to ensure the dust removal effect.

[0051] As an improvement of this embodiment, in order to reduce water resource waste, the water source for spray dust removal comes from a circulation pool that collects waste water from cooling water, and after filtration and sedimentation, it is reused for spray dust removal. The specific steps include: collecting the cooling water for water-cooling the rolling rolls and steel to the circulation pool; filtering and sedimenting the waste water in the circulation pool; using the waste water in the circulation pool for spray dust removal through the frequency conversion pump. In order to further utilize water resources, the waste water after spray dust removal is also collected to the circulation pool. Specifically, the process of recycling water resources includes S1401, collecting the water after spray dust removal to the circulation pool, and collecting the cooling water for water-cooling the rolling rolls and steel to the circulation pool; S1402, filtering and sedimenting the waste water in the circulation pool; S1403, using the waste water in the circulation pool for spray dust removal through the frequency conversion pump. It should be noted that during the production process of the rolling mill, the waste water can come from the cooling water for cooling the rolling rolls and steel, the cleaning water before steel rolling, the cleaning water after leakage of the lubrication system, or the pickling waste water for surface treatment during the rolling process. However, in the specific implementation process, in order to save the cost of treating waste water, only the cooling water for cooling the rolling rolls and steel is utilized as the waste water source.

[0052] In order to further improve the dust removal effect, the nozzle is a spiral nozzle that can generate solid cone or hollow cone spray. The atomization angle of the spiral nozzle is 60°-170°. Using a spiral nozzle that can generate solid or hollow cone spray with an atomization angle of 60°-170° ensures a wide and uniform spray coverage range, improving the dust removal efficiency. It should be noted that the spiral nozzle is a high-efficiency atomizing nozzle with an atomization angle range of 60° to 170°, which can be flexibly selected according to different application scenarios. The inside of the nozzle adopts an unobstructed design, that is, it is a smooth passage from the inlet to the outlet, ensuring that the liquid can pass through smoothly, greatly reducing the risk of blockage, especially suitable for complex working conditions such as waste water containing impurities. The atomization principle of the nozzle is based on its unique spiral structure. When water flow enters the nozzle, it is split into multiple tiny droplets through impact with the spiral layered interface, thus forming a layered spraying effect. Each spiral nozzle usually has 3 to 4 spraying layered interfaces, and these layered interfaces interact with each other to enable the spray to form a uniform atomization effect, significantly improving the spray coverage range and atomization quality. This high-efficiency atomization characteristic enables the spiral nozzle to effectively remove suspended solids in the air and is widely used in fields such as dust removal, cooling, and humidification. Its unique structural design and atomization mechanism not only ensure the atomization effect but also have excellent anti-blocking ability, suitable for the scenario of spray dust removal using waste water.

[0055] Embodiment 3

[0056] In this embodiment, each embodiment of the present invention will be described in detail below with reference to the drawings.

[0057] Figure 2 The structure of the rolling mill spray dust removal device for implementing the rolling mill spray dust removal system is described as a whole. Specifically, Figure 2 is a schematic structural diagram of a rolling mill spray dust removal device according to an embodiment of the present invention.

[0058] As Figure 2 shown, the rolling mill dust removal device for implementing the rolling mill spray dust removal system of the present invention mainly includes a variable frequency pump 1 for adjusting the spray pressure, a water cut-off valve 3, a water inlet pipe 2, a nozzle 13, a vertical adjustment sleeve for adjusting the vertical position of the nozzle 13, and a horizontal adjustment sleeve for adjusting the horizontal position of the nozzle 13; wherein, the variable frequency pump 1 is arranged at the output end of a circulating water tank for collecting rolling mill dust removal wastewater, and the water inlet pipe 2 is communicated with the output end of the variable frequency pump 1; the water inlet pipe 2 is sequentially communicated with the vertical adjustment sleeve and the horizontal adjustment sleeve, and the nozzle 13 is arranged at the end of the horizontal adjustment sleeve; a water cut-off valve 3 is arranged on the water inlet pipe 2. That is to say, the water inlet pipe 2, the vertical adjustment sleeve and the horizontal adjustment sleeve are sequentially connected outside the circulating water tank, and then the nozzle 13 is arranged at the end of the horizontal adjustment sleeve. Specifically, it further includes a first 90° elbow 7 for changing the water flow direction and connecting the vertical adjustment sleeve and the horizontal adjustment sleeve; and a second 90° elbow 11 for connecting the horizontal adjustment sleeve and the nozzle 13.

[0059] In a specific implementation process, in order to further improve the stability of the structure, the vertical adjustment sleeve is fixedly arranged on the ground through a base 4. A vertical fixing sleeve 6 is movably arranged on the outer periphery of the vertical adjustment sleeve, and a horizontal fixing sleeve 10 is movably arranged on the outer periphery of the horizontal adjustment sleeve. The vertical fixing sleeve 6 and the horizontal fixing sleeve 10 are connected by a reinforcing rod 14. The vertical adjustment sleeve includes a metal hose 8 and a vertical water pipe 5 which are sleeved with each other, and the vertical fixing sleeve 6 is arranged on the vertical water pipe 5. The horizontal adjustment sleeve includes a metal hose 8 and a horizontal water pipe 9 which are sleeved with each other, and the horizontal fixing sleeve 10 is arranged on the horizontal water pipe 9. The vertical fixing sleeve 6, the horizontal fixing sleeve 10 and the reinforcing rod 14 form a stable triangular structure for supporting the entire spraying system to ensure its stable operation. The vertical fixing sleeve 6 is movably arranged on the outer periphery of the vertical water pipe 5 and can slide and be locked on the vertical water pipe 5. Exemplarily, a sliding chamber is provided inside the vertical adjustment sleeve 5. The vertical water pipe 5 is inserted into the sliding chamber and can slide axially. A locking device including a beam clamp and an eccentric locking handle is provided. A limiting block is arranged inside the beam clamp and fits with the planar structure of the outer wall of the vertical water pipe 5, and locking and unlocking are achieved through the eccentric locking handle. The movable and lockable connection relationship can also be a lock pin and a pull rod, a fixed rod and a compression spring, etc., which are not specifically limited here. The working principle of sliding is that the vertical water pipe 5 is inserted into the sliding chamber of the vertical fixing sleeve 6, and the sliding function is achieved through the limiting block or the fixed rod. A planar structure or a jack can be arranged on the outer wall of the vertical water pipe 5 to cooperate with the locking device to achieve guiding and positioning during sliding. The working principle of locking is that an eccentric locking handle or a lock pin structure is adopted. When fixation is required, the locking device is switched to the locking position by operating the handle or the pull rod. A compression spring is used to provide the locking force to ensure that the vertical water pipe 5 will not loosen in the locked state. When adjustment is required, the locking device is operated to switch to the unlocking position, and the vertical fixing sleeve 6 can freely slide along the vertical water pipe 5. Specifically, the water inlet pipe 2 is connected with a water cut-off valve 3. Water flows through the vertical water pipe 5, passes through the elbow 7 and the metal hose 8 and is sent to the nozzle 13. The vertical fixing sleeve 6 can only move up and down along the pipeline 5, and the horizontal fixing sleeve 10 can only move horizontally along the horizontal pipe. Fixed buckles are arranged on both sides of the sleeve. The reinforcing rod 14 can be telescopically adjusted. The vertical fixing sleeve 6, the horizontal fixing sleeve 6 and the reinforcing rod 14 are used to fix and adjust the spraying points, realizing precise control of the spraying points.

[0060] As an improvement of this embodiment, the nozzle 13 is a spiral nozzle with an atomization angle of 60° to 170°. Specifically, the atomization angle of the spiral nozzle is 60° - 170°. There is no internal structure in the nozzle, which is a smooth channel. The water flow generates stratified spraying by hitting the spiral stratified interface. Each single spiral nozzle has 3 to 4 stratified interfaces for spraying, with good atomization effect, which can effectively remove suspended substances in the air; a large amount of impurities in the wastewater can pass through the nozzle without causing blockage. It is applicable to the scenario of spray dust removal for wastewater.

[0061] As an improvement of this embodiment, an anti-collision cover 12 is provided outside the nozzle 13. It is arranged outside the nozzle and is used to protect the nozzle.

[0062] Furthermore, the preferred structure is that it further includes a control module for connecting the water cut-off valve 3, the nozzle 13, and the variable-frequency pump 1. The control module includes a nozzle position adjustment unit, which is used to obtain the smoke amount data at the corresponding dust removal working position of the rolling mill at each dust removal working position by using the smoke concentration monitoring sensor; and adjust the position of the nozzle 13 for dust removal spraying according to the obtained smoke amount data at each dust removal working position. The control module also includes a nozzle pressure adjustment unit, which is used to determine the required spraying pressure according to the smoke amount data at the corresponding dust removal working position of the nozzle 13; control the water supply pressure by adjusting the rotation speed of the variable-frequency pump 1 according to the required spraying pressure, and perform spray dust removal at the corresponding dust removal working position of the nozzle 13. The control module also includes a dust removal point control unit, which is used to detect the roll biting signal and the roll stripping signal by using the roll biting sensor and the roll stripping sensor at the dust removal working position; when the roll biting sensor detects the roll biting signal, start spray dust removal by controlling the water cut-off valve 3 and the variable-frequency pump 1; when the roll stripping sensor detects the roll stripping signal, stop spray dust removal by controlling the water cut-off valve 3 and the variable-frequency pump 1. In the process of adjusting the position of the nozzle for dust removal spraying according to the obtained smoke amount data at each dust removal working position; and determining the required spraying pressure according to the smoke amount data at the corresponding dust removal working position of the nozzle, machine learning methods are used to predict the ideal spraying parameters, and the machine learning model can be integrated into the automated control system to realize the automated adjustment of the spraying system and reduce the workload of the operators. In summary, the application of machine learning technology in the spray dust removal system can not only improve the dust removal effect, but also optimize the resource utilization, enhance the automated level and overall performance of the system.

[0063] For the present invention, the control module can set up an automatic control system based on a PLC (Programmable Logic Controller). That is to say, through the control unit combined with multiple sensors, more complex control logics can be achieved. The control unit can also be provided with a fault diagnosis and alarm function. When a sensor fails, the system can automatically give an alarm and take corresponding emergency measures. Exemplarily, a fault alarm mechanism is set up in the system. When devices such as the water cut-off valve, sensor, and variable frequency pump fail, an alarm is issued in time and the spraying is stopped. The system has a manual operation mode for emergency operations when the automatic control fails.
