Description

Technical Field

[0001] This invention belongs to the field of hot-rolled stainless steel technology, and specifically relates to a purification and treatment device for laminar flow spray turbid liquid of hot-rolled stainless steel. Background Technology

[0002] In the hot rolling process of steel mills, the steel undergoes heating, rough rolling, and finish rolling before entering the laminar flow cooling device. Through laminar flow cooling, stainless steel under different working conditions is rapidly cooled from a relatively high final rolling temperature to the required coiling temperature, so that the stainless steel can obtain good microstructure and mechanical properties. The water used in the laminar flow cooling manifold has relatively low requirements for water quality.

[0003] A search revealed a high-efficiency, energy-saving hot-rolled laminar flow cooling water circulation system treatment device with publication number CN116750820A. This device includes a laminar flow iron sheet pit, a pump to the cold water tank, and a pump to the filter and cooling tower. The pump to the cold water tank draws water from the laminar flow iron sheet pit to the downstream cold water tank, and the pump to the filter and cooling tower draws water from the laminar flow iron sheet pit to the side-spray cold water tank. The side-spray cold water tank is connected to the downstream cold water tank via an overflow outlet. However, this treatment process has the following drawbacks: some wastewater directly enters the downstream cooling water tank through the laminar flow iron sheet pit, resulting in some impurities in the wastewater not being filtered. This further causes the impurities to adhere to the laminar flow spray nozzles, leading to nozzle blockage and affecting the cooling efficiency of the stainless steel.

[0004] A search revealed that the existing technology announcement number CN218794450U describes a water treatment device for a laminar flow cooling system of hot-rolled strip. This device includes a cooling water treatment system comprising clean cold return water and dirty hot return water. A cooling tower is located on one side of the cooling water treatment system, a dirty hot return water pool is located on one side of the cooling tower, a filter box is located on one side of the dirty hot return water pool, a clean cold return water pool is installed on one side of the filter box, and a laminar flow hot water pool is located at one end of the dirty hot return water pool. A first connecting pipe is inserted into one end of the clean cold return water pool, and the other end of the first connecting pipe is flush with one side of the clean cold return water pool. The system is interconnected, with a second connecting pipe inserted at the bottom of the cold clean return water tank, the other end of which is connected to the cooling water treatment system. A third connecting pipe is inserted at one end of the hot dirty return water tank. The treatment process has the following drawbacks: the magnetic filter, the filter screen, and the second activated carbon filter are inconvenient to clean, and prolonged use can easily cause blockage of these filters, thus affecting wastewater treatment; the cooling fan can only cool the surface of the wastewater, making it impossible to cool the wastewater quickly and evenly, further affecting the uniformity of laminar flow cooling and thus reducing the quality of the stainless steel. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a purification treatment device for hot-rolled stainless steel laminar flow spray turbid liquid. The filtration mechanism can reduce filter plate clogging and improve filter plate filtration efficiency; at the same time, it is convenient to clean oxide scale; the coordinated movement of the sedimentation cylinder, buffer zone, extraction mechanism and cooling mechanism is conducive to the precipitation of oxide scale and impurities in the turbid liquid; it can uniformly cool the supernatant for laminar flow cooling and realize the recycling of heat.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

The filter box contains two sets of filtration mechanisms and an obliquely arranged baffle, with the two sets of filtration mechanisms located on opposite sides of the baffle. The sedimentation tank, buffer zone, and cooling tower are all located on one side of the filter box, and the filter box and sedimentation tank are connected by the water pump and connecting pipe. The sedimentation tank and cooling tower are fixed to the top of the buffer zone and are respectively connected to the buffer zone. An extraction mechanism is located at the center of the cooling tower, and cooling mechanisms are installed on the side walls of the cooling tower around the extraction mechanism. The inlet is located at the top of the filter box, and the outlet pipe is fixed to the side wall of the cooling tower. The buffer zone side wall is equipped with… There are multiple sets of sewage pipes, which are connected to the sludge pump and equipped with solenoid valves. Turbid liquid enters the filter box through the inlet and is filtered by the filtration mechanism to remove the oxide scale. The filtered turbid liquid enters the sedimentation tank through the pump and connecting pipe and flows downward to the buffer zone, where it settles. The supernatant flows through the buffer zone to the bottom buffer zone of the cooling tower. The extraction mechanism drives the supernatant upward and then into the cooling mechanism for further cooling. The cooled supernatant is extracted through the outlet pipe for laminar flow cooling. Finally, the sludge pump discharges the sediment at the bottom of the buffer zone through the sewage pipe.

[0008] The filtration mechanism includes a filter plate, a fixed plate, a rotating shaft, an electric push rod I, a sealing door, a baffle, an electric push rod II, and a collection box. The fixed plate is fixed to the side wall of the partition, the rotating shaft is connected to the fixed plate, and the filter plate is rotatably mounted on the rotating shaft. The electric push rod I is connected to the side wall of the filter box, and its output end is connected to the end of the filter plate away from the partition. A slag outlet is provided on the side wall of the filter box, corresponding to the filter plate. The sealing door is installed at the slag outlet, and the baffle is located on the top of the filter plate on one side of the sealing door, and the baffle is connected to the side wall of the sealing door. The electric push rod II is fixed to the inner wall of the filter box, and its output end is connected to the top of the sealing door and the baffle. The collection box is fixed to the outer wall of the filter box below the slag outlet. The electric push rod I provides power to drive the filter plate to rotate around the rotating shaft, thereby tilting the filter plate, which can reduce filter plate clogging and improve filter plate filtration efficiency. When the filtration mechanism needs cleaning, the electric push rod II provides power to drive the baffle and the sealing door to move upward, thereby opening the slag outlet, which facilitates the discharge of oxide scale through the slag outlet to the collection box for temporary storage.

[0009] The filter plate is equipped with a vertical filtration mechanism, which includes a filter cylinder, sprocket I, chain I, gear, and motor II. Several filter cylinders are evenly distributed on the filter plate. Several sprockets I are fixed to the bottom of their respective filter cylinders.

Motor II provides power to drive the gear to rotate, which in turn drives the meshing sprockets I to rotate. Sprocket I, through chain I, drives other sprockets I to rotate, further driving the filter cylinder to rotate. This allows the oxide scale on the filter cylinder to be removed, preventing filter cylinder clogging and facilitating oxide scale cleaning.

[0010] The filter plate has a moving mechanism at its bottom, which includes a support frame, a lead screw, a motor III, a connecting ring, and a connecting plate.

A pair of fixed rings are provided on the side wall of the filter cylinder near the bottom, and a connecting ring is movably connected between the fixed rings.

The motor III provides power to drive the lead screw to rotate, and the lead screw drives the filter cylinder to move along the filter plate through the connecting plate and the connecting ring, thereby moving the filter cylinder to the top of the filter cylinder and flush with the filter plate. During the movement of the filter cylinder, the filter plate can scrape off the residual oxide scale on the side wall of the filter cylinder, leaving the oxide scale on the upper surface of the filter plate, which further facilitates oxide scale cleaning.

[0011] A scraping mechanism is provided above the filter plate, which includes a scraper, a telescopic plate, a gas spring, and a motor VII. The scraper is located at the top of the filter plate, and a limiting groove is provided inside the scraper. The gas spring is installed in the limiting groove, and one end of the telescopic plate is installed in the limiting groove and connected to one end of the gas spring. The motor VII is equipped with a waterproof shell and is fixed to the bottom of the filter plate. The output end is connected to the end of the scraper away from the telescopic plate. When the filter mechanism needs to be cleaned, the moving mechanism moves the filter cylinder to the top of the filter cylinder and flush with the filter plate. Then, the motor VII provides power to drive the scraper to rotate, and the scraper drives the telescopic plate to move along the filter plate, thereby scraping off the oxide scale on the filter plate and discharging it through the slag outlet.

[0012] The extraction mechanism includes an extraction shell, spiral blades, a main shaft, bevel gear I, motor V, bevel gear II, support plate II, and spiral heat exchange tubes. The extraction shell is located inside the cooling tower, and its bottom is fixed to the buffer zone at the end away from the sedimentation tank.

The two ends of the main shaft are connected to the top of the cooling tower and support plate II respectively through bearings. The inside of the main shaft is hollow. The spiral blades are located inside the extraction shell and fixed to the main shaft. Bevel gear I is connected to one end of the main shaft. Motor V is fixed to the top of the cooling tower. The output shaft is provided with bevel gears. Wheel II, bevel gear I and bevel gear II are meshed and connected; several spiral heat exchange tubes are provided, evenly fixed inside the spiral blades, and the water inlet and outlet both extend through the main shaft to the outside of the cooling tower; motor V provides power to drive the main shaft to rotate through bevel gear II and bevel gear I, the main shaft drives the spiral blades to rotate, thereby driving the supernatant in the buffer zone to flow upward along the spiral blades and be discharged through the outlet; during the upward flow of the supernatant along the spiral blades, heat exchange is carried out on the supernatant through the spiral heat exchange tubes, which can cool the supernatant for laminar flow cooling and also realize the recycling of heat.

[0013] The cooling mechanism includes a ring, a guide plate, a fixed seat, a tension spring, a fixed frame, a threaded rod, a movable plate, a chain II, a motor VI, and a heat exchange tube. A pair of mounting slots and a pair of guide slots are provided on the inner wall of the cooling tower. The ring is fixed to the side wall of the extraction shell. Several fixed seats are provided, evenly installed in the mounting slots on the inner wall of the cooling tower. The guide plate is semi-circular in shape and has a connecting seat, which is rotatably connected to the fixed seat via a rotating shaft. One end of the tension spring is fixed to the lower surface of the ring, and the other end is connected to the upper surface of the guide plate. A pair of fixed frames are provided, symmetrically fixed to the outer wall of the cooling tower. The threaded rod is rotatably connected to the fixed frame via a bearing, and a sprocket II is provided at the top of the threaded rod. The sprockets II are connected to each other via a chain II. One end of the movable plate is connected to the threaded rod via a thread, and the other end is connected to the top of the cooling cylinder. The unit is connected to the interior of the cooling tower; a pressure plate is provided on the side wall inside the cooling tower, corresponding to the guide plate and located at the top of the guide plate; motor VI is fixed to the bottom of the fixed frame and connected to one end of the threaded rod; several heat exchange tubes are provided, evenly distributed inside the cooling tower; motor VI provides power to drive the threaded rod to rotate, and at the same time drives another threaded rod to rotate through sprocket II and chain II; the threaded rod drives the movable plate to move downward along the guide groove through the thread, and the movable plate drives the guide plate to rotate downward around the pivot point through the pressure plate, and the tension spring is stretched; when the movable plate drives the pressure plate to move upward, the tension spring recovers, driving the guide plate to rotate upward, thereby adjusting the tilt angle of the guide plate, further adjusting the flow speed of the supernatant on the guide plate; further accelerating the cooling of the supernatant, ensuring uniform cooling of the supernatant.

[0014] The filter box is equipped with a water inlet mechanism at the top, which includes a mounting plate, a water guide plate, and a motor I. A pair of symmetrically arranged support plates are located on the inner wall of the filter box near the top. A pair of mounting plates are also symmetrically fixed to the inner wall of the filter box. One end of the water guide plate is rotatably connected to the mounting plate via a rotating shaft, and the bottom of the water guide plate overlaps the support plate. The motor I provides power to drive the water guide plate to rotate, thereby adjusting the position of the water guide plate and further adjusting the flow direction of the turbid liquid. This allows for simultaneous turbid liquid filtration and filter mechanism cleaning, further improving the filtration efficiency of the turbid liquid.

[0015] The sedimentation tank is equipped with an auger and a support plate I. The two ends of the auger are rotatably connected to the support plate I and the top of the sedimentation tank via bearings. A motor IV is located at the top end of the auger in the sedimentation tank. The filtered turbid liquid enters the sedimentation tank through a connecting pipe and flows downward along the auger into the buffer zone for sedimentation. The motor IV provides power to drive the auger to rotate, thereby transporting the sediment generated on the auger surface to the buffer zone, preventing the sediment on the auger from affecting the flow of the turbid liquid. At the same time, the spiral auger in the sedimentation tank effectively reduces the impact force of the wastewater entering the sedimentation tank, avoiding excessive impact force from causing the settled sediment to move.

[0016] The inner sidewall of the buffer zone is provided with several baffles arranged in an alternating pattern; the baffles can slow down the flow of the turbid liquid, thereby facilitating the precipitation of oxide scale and impurities in the turbid liquid.

[0017] The advantages of this invention compared to existing technologies are as follows:

During the movement of the filter cylinder, the filter plate can scrape off the residual oxide scale on the side wall of the filter cylinder, so that the oxide scale is left on the surface of the filter plate, which further facilitates oxide scale cleaning;

[0019] 2) In the cooling mechanism, motor VI provides power to drive the threaded rod to rotate, and at the same time, it drives another threaded rod to rotate through sprocket II and chain II. The threaded rod drives the movable plate to move downward along the guide groove through the thread. The movable plate drives the guide plate to rotate downward around the pivot shaft through the pressure plate, and the tension spring is stretched. When the movable plate drives the pressure plate to move upward, the tension spring recovers and drives the guide plate to rotate upward, which can adjust the tilt angle of the guide plate, thereby adjusting the flow speed of the supernatant on the guide plate; further accelerating the cooling of the supernatant and ensuring uniform cooling of the supernatant.

[0042] The filter box 1 is equipped with a water inlet mechanism 103 at the top. The water inlet mechanism 103 includes a mounting plate 1031, a water guide plate 1032, and a motor I 1033. A pair of symmetrically arranged support plates 102 are provided on the inner side wall of the filter box 1 near the top. A pair of mounting plates 1031 are symmetrically fixed to the inner side wall of the filter box 1. One end of the water guide plate 1032 is rotatably connected to the mounting plate 1031 through a rotating shaft, and the bottom of the water guide plate 1032 overlaps the support plate 102. The motor I 1033 provides power to drive the water guide plate 1032 to rotate, which can adjust the position of the water guide plate 1032 and then adjust the flow direction of the turbid liquid. This allows the turbid liquid filtration and the cleaning of the filter mechanism 2 to be carried out simultaneously, further improving the filtration efficiency of the turbid liquid.

[0043] The sedimentation cylinder 3 is equipped with an auger 301 and a support plate I 303. The two ends of the auger 301 are rotatably connected to the support plate I 303 and the top of the sedimentation cylinder 3 respectively through bearings. A motor IV 302 is installed at the top end of the auger 301. The filtered turbid liquid enters the sedimentation cylinder 3 through the connecting pipe 11 and flows downward along the auger 301 into the buffer zone 4 for sedimentation. The motor IV 302 provides power to drive the auger 301 to rotate, thereby transporting the sediment generated on the surface of the auger 301 to the buffer zone 4, preventing the sediment on the auger 301 from affecting the flow of the turbid liquid. At the same time, the setting of the spiral auger 301 in the sedimentation cylinder 3 effectively reduces the impact force of the turbid liquid entering the sedimentation cylinder 3, and avoids the excessive impact force from causing the settled sediment to move.

[0044] The inner wall of the buffer zone 4 is provided with staggered baffles 401; the baffles 401 can slow down the flow of turbid liquid, thereby facilitating the precipitation of oxide scale and impurities in the turbid liquid.

[0045] A laminar flow spray turbid liquid purification device for hot-rolled stainless steel operates as follows: The turbid liquid enters the filter box 1 through the inlet 8. The electric push rod I 204 provides power to drive the filter plate 201 to rotate around the rotating shaft 203, thereby tilting the filter plate 201, which reduces clogging and improves the filtration efficiency. When the filter mechanism 2 needs cleaning, the electric push rod II 210 provides power to move the baffle 209 and the sealing door 208 upward, thereby opening the slag outlet 101 to facilitate the passage of oxide scale. 101 is discharged to the collection tank 211 for temporary storage; the filtered turbid liquid enters the sedimentation tank 3 through the water pump 9 and the connecting pipe 11; and flows downward along the screw conveyor in the sedimentation tank 3 to the interior of the buffer zone 4, where it settles. The supernatant flows through the buffer zone 4 to the bottom of the cooling tower 5, and the extraction mechanism 6 drives the supernatant to flow upward, and then enters the cooling mechanism 7 for further cooling. The cooled supernatant is extracted through the outlet pipe for laminar flow cooling; finally, the sludge pump 14 discharges the sediment at the bottom of the buffer zone 4 through the drain pipe 13.
