Description

Technical Field

[0001] This invention relates to the field of sewage discharge devices for steelmaking and metallurgical equipment, specifically an automatic detection and sewage discharge device for sludge in the water seal box of a converter purification system. Background Technology

[0002] Wet scrubbing, with its simple structure and low maintenance, is the most widely used converter flue gas purification system in the world. The flue gas produced during converter smelting is dissolved in the system's scrubbing water, and the clean gas is then released into the atmosphere. A large amount of scrubbing water, sprayed into a mist by system nozzles, combines with the flue gas dust and accumulates in the water seal tank. The scrubbing water in the water seal tank overflows through an overflow pipe and returns to the wastewater treatment plant, where it is recycled after sedimentation, flocculation, and conditioning. However, the scrubbing water accumulating in the water seal tank contains a large amount of sludge, which is carried away by the overflow pipe, leaving some sediment at the bottom of the water seal tank. When this sludge is not effectively removed, it can clog the overflow pipe, the water seal tank itself, and related drainage pipes and equipment, thus affecting the overall efficiency of the flue gas purification system. Therefore, an automatic sludge detection and drainage device for the water seal tank of a converter purification system is needed to solve this problem.

[0003] Based on this, Chinese patent application CN201120216442.1 discloses a leak-proof converter gas negative pressure water seal device, which includes a water seal box, a drain pipe, a drain valve, a water inlet pipe, a water inlet valve, a gas outlet pipe, an exhaust valve, and a gas discharge pipe. The advantage is that the device prevents the gas in the converter gas negative pressure water seal from overflowing, thereby ensuring the safe production of the surrounding operating positions.

[0004] However, this patent application has shortcomings: when using a traditional converter gas negative pressure water seal device, the water seal box in the device lacks the effect of detecting sludge and discharging sewage. With long-term use of the device, a large amount of sludge will settle at the bottom of the water seal box. Over time, this sludge will continue to accumulate and occupy the effective volume of the water seal box, affecting its normal operation. When the sludge is not effectively removed, it may cause blockage of the overflow pipe, water seal box, sewage pipe and equipment, thereby affecting the operating efficiency of the entire flue gas purification system.

[0005] To address the aforementioned issues, an automatic detection and discharge device for sludge in the water seal box of a converter purification system is proposed. Summary of the Invention

[0006] The purpose of this invention is to provide an automatic sludge detection and discharge device for the water seal box of a converter purification system. Using this device solves the problems mentioned above, where traditional water seal boxes lack sludge detection and discharge capabilities. Long-term use of the device leads to a large amount of sludge settling at the bottom of the water seal box. Over time, this sludge accumulates, occupying the effective volume of the water seal box and affecting its normal operation. When the sludge is not effectively removed, it may cause blockages in the overflow pipe, the water seal box itself, and the discharge pipes and equipment, thus affecting the overall operating efficiency of the flue gas purification system.

[0012] Preferably, a spring is fixedly connected between the rotating pressure plate and the connecting plate, and two sets of the spring are provided. A connecting rope is fixedly connected to one side of the rotating pressure plate, and two sets of the connecting rope are provided. A through-hole is provided on one side of the connecting plate, and the two sets of connecting ropes pass through the through-hole and are fixedly connected to the sliding ring.

[0013] Preferably, a scraping ring is slidably connected to the inner wall of the through pipe, an impeller component is rotatably connected to the inner cavity of the through pipe, and a reciprocating lead screw is rotatably connected inside the through pipe.

[0014] Preferably, a movable plate is fixedly connected to one side of the scraping ring, and the movable plate is threaded to the outer periphery of the reciprocating lead screw.

[0015] Preferably, a first bevel gear is rotatably connected inside the mounting box, a second bevel gear is meshed with one side of the first bevel gear, the second bevel gear is fixedly connected to the reciprocating lead screw, and one side of the first bevel gear is fixedly connected to the impeller component via a connecting rod.

[0016] Preferably, the intelligent controller is electrically connected to the ultrasonic mud level gauge, the drive motor, the pneumatic regulating valve and the solenoid valve, respectively, and the outer wall of the scraping ring is in contact with the inner wall of the through pipe.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0018] 1. When using the device described in this application, the mixed materials enter the water seal tank chamber through the pneumatic regulating valve. The gas washing water in the water seal tank chamber overflows through the side-designed overflow pipe and returns to the sewage treatment plant via a chute. After sedimentation, flocculation, and conditioning, it is recycled. However, the washing water that accumulates in the water seal tank is combined with flue dust and contains a large amount of sludge. Most of the sludge is carried away by the water seal overflow pipe, but some still settles at the bottom of the water seal tank. The water seal tank chamber is equipped with an ultrasonic sludge level gauge. The ultrasonic sludge level gauge uses sensor signals and automatic control program technology to realize real-time monitoring of the sludge height in the water seal tank chamber. The system monitors and, based on data feedback, allows the main controller to set and adjust operating parameters to optimize the performance of the entire purification system and the water seal. When the ultrasonic sludge level gauge detects that the sludge level exceeds the safe range, it sends a signal to the intelligent controller. The intelligent controller then controls the drive motor to start the working mode and simultaneously controls the solenoid valve to open the pipe outlet. The drive motor then rotates the crushing blade assembly, which stirs and crushes the sludge accumulated inside the water seal tank, preventing large clumps of sludge from remaining inside the tank. The dispersed sludge is discharged through the pipe and leaves the device, thus enabling unified sludge treatment.

[0019] 2. This application redesigns the water seal box in two aspects. First, the manual drain valve of the water seal box is improved into a pneumatic regulating valve. Second, the structure of the discharge hopper at the bottom of the water seal box is improved so that the discharge hopper is tilted to reduce sludge deposition and facilitate sludge discharge. The pneumatic regulating valve monitors the sludge height in the water seal box in real time. When the sludge reaches the set height, the speed of the dust removal fan and the non-smelting time of the converter are set. When the three signals are simultaneously detected by the PLC, the pneumatic regulating drain valve of the water seal box is automatically activated to ensure that the sludge is effectively removed without interfering with normal operation. This setting adds sludge detection and treatment to the water seal box. The main purpose is to solve the problem of sludge accumulation in the device, prevent the overall device from becoming blocked, avoid affecting the normal operation of the device, eliminate system blockage and water waste, reduce the labor intensity of the staff, and improve the working efficiency of the equipment.

[0020] 3. During the discharge of the dispersed and crushed sludge from the through-pipe, the flowing sludge material causes the impeller component to rotate. The impeller component drives the first bevel gear, the second bevel gear, and the reciprocating screw to rotate. The reciprocating screw drives the scraping ring to move up and down along the through-pipe, and the moving plate slides up and down along the reciprocating screw. The outer wall of the scraping ring is tightly attached to the inner wall of the through-pipe. The scraping ring moves back and forth in the through-pipe, thus cleaning the inner wall of the through-pipe and preventing the accumulation of sludge impurities on the inner wall of the through-pipe. This improves the anti-clogging performance of the through-pipe and increases the working efficiency of the device.

[0021] 4. Traditional water seal tank designs require regular manual sludge removal and cleaning. Furthermore, traditional water seal tanks are inconvenient for operators to open and close, hindering internal cleaning. After use, the user can remove the tank cover from the top of the water seal tank for easy cleaning and maintenance. After cleaning, the cover is reattached to the top of the tank, preparing for future operation. To prevent leakage, the cover and tank can be securely tightened. The first motor is then started, driving the threaded rod to rotate forward. This causes the sliding ring to slide horizontally towards the first support ring. The sliding ring pulls multiple connecting ropes, which in turn pull the rotating pressure plates downwards until the tops of the two rotating pressure plates are firmly pressed and fixed to the top of the cover. Multiple springs... With the spring compressed and the first motor shut off, the two sets of pressing components reinforce the water seal tank cavity and the tank cover, allowing the water seal tank assembly to continue operating. When the water seal tank assembly needs to be opened again, the user drives the first motor to rotate the threaded rod. The threaded rod causes the sliding ring to move away from the first support ring. At this time, the multiple connecting ropes are relaxed, generating a thrust on the springs. The springs push the rotating pressure plates at their respective positions to lift upwards, thus the two sets of rotating pressure plates cease pressing the tank cover. This allows the operator to easily remove the tank cover from the top of the water seal tank cavity. This clamping and reinforcing design helps prevent material leakage when the water seal tank tilts or shakes, ensuring the device operates in a stable environment. The device is also easy for the operator to open, facilitating cleaning of the inside of the water seal tank and ensuring the quality of use for the user.

[0022] 5. The device of this invention introduces pneumatic regulating valves for automatic detection and sewage discharge, reducing the need for manual sludge removal, improving operational efficiency, and reducing labor intensity. The automatic sludge removal design of the device can prevent excessive sludge accumulation, thereby extending the maintenance cycle of the water seal tank components and equipment and reducing maintenance time. Although the initial investment may increase, in the long run, the automation system can reduce labor costs and lower maintenance and repair expenses, thus reducing the overall operating cost. The automatic detection and sewage discharge system reduces the need for personnel to come into contact with hazardous environments, reducing the operational risks of the device. The design takes into account different working conditions and varying sludge deposition rates, enabling the device to adapt to various working environments. The integrated automatic control system provides real-time data and an operating interface, facilitating operator monitoring and enabling remote management of the entire process.

[0042] In summary, this invention proposes an automatic sludge detection and discharge device for a converter purification system's water seal box. Traditional water seal boxes lack the ability to detect and discharge sludge. Long-term use of such devices leads to a large amount of sludge settling at the bottom of the water seal box. Over time, this sludge accumulates, occupying the effective volume of the water seal box and affecting its normal operation. When using the device of this application, the mixed materials enter the water seal tank 11 through the pneumatic regulating valve 14. The gas washing water in the water seal tank 11 overflows through a side-designed overflow pipe to a chute, returning to the wastewater treatment plant for sedimentation, flocculation, and conditioning before being recycled. However, the sludge accumulating inside the water seal box... The washing water is combined with flue gas and contains a large amount of sludge. Most of the sludge is carried away by the water seal overflow pipe, but some still settles at the bottom of the water seal tank. The water seal tank chamber 11 is equipped with an ultrasonic sludge level gauge 114. Using sensor signals and automatic control technology, the ultrasonic sludge level gauge 114 monitors the sludge level in the water seal tank chamber 11 in real time. Based on the data feedback, the main controller can set and adjust operating parameters to optimize the performance of the entire purification system and the water seal. When the ultrasonic sludge level gauge 114 detects that the sludge level exceeds the safe range, it sends a signal to the intelligent controller 15, which then controls the drive motor 112 to start operation. In operation mode, the intelligent controller 15 controls the solenoid valve 33 to open the port end of the pipe 31, driving the motor 112 to rotate the crushing blade assembly 113. The crushing blade assembly 113 stirs and crushes the sludge accumulated inside the water seal tank 11, preventing large clumps of sludge from remaining inside the water seal tank 11. The dispersed sludge will be discharged from the pipe 31 and leave the device, thus uniformly treating the sludge. This application redesigns the water seal tank in two aspects: firstly, the manual drain valve of the water seal tank is improved to a pneumatic regulating valve 14; secondly, the structure of the discharge hopper 13 at the bottom of the water seal tank is improved so that the discharge hopper 13 is tilted. To reduce sludge deposition and facilitate sludge discharge, a pneumatic regulating valve 14 is used to monitor the sludge height in the water seal box in real time. When the sludge reaches the set height, the speed of the dust removal fan and the non-smelting time of the converter are set. When the three signals are simultaneously satisfied by the PLC detection, the pneumatic regulating drain valve of the water seal box is automatically activated, ensuring that the sludge is effectively removed without interfering with normal operation. This setting adds sludge detection and treatment to the water seal box. The main purpose is to solve the problem of sludge accumulation in the device, prevent the overall device from becoming blocked, avoid affecting the normal operation of the device, eliminate system blockage and water waste, reduce the labor intensity of the staff, and improve the working efficiency of the equipment.

[0043] During the discharge of the dispersed and crushed sludge from the through-pipe 31, the flowing sludge material causes the impeller component 35 to rotate as it passes through the through-pipe 31. The impeller component 35 drives the first bevel gear 36, the second bevel gear 37, and the reciprocating screw 38 to rotate. The reciprocating screw 38 drives the scraping ring 34 to move up and down along the through-pipe 31. The moving plate 39 slides up and down along the reciprocating screw 38. The outer wall of the scraping ring 34 is tightly attached to the inner wall of the through-pipe 31. The scraping ring 34 moves back and forth in the through-pipe 31, thereby cleaning the inner wall of the through-pipe 31, preventing the accumulation of sludge impurities on the inner wall of the through-pipe 31, improving the anti-clogging performance of the through-pipe 31, and increasing the working efficiency of the device.

[0044] Traditional water seal tank designs require regular manual sludge removal and cleaning. Furthermore, traditional water seal tanks are inconvenient for operators to open and close, hindering internal cleaning. After use, the user can remove the cover 12 from the top of the water seal tank 11, facilitating cleaning and maintenance. After cleaning, the cover 12 is reattached to the top of the water seal tank 11, preparing for subsequent operation. To prevent material leakage from the water-sealed tank chamber 11, the tank cover 12 and the water-sealed tank chamber 11 are reinforced tightly. The first motor 24 is started, driving the threaded rod 25 to rotate forward. The threaded rod 25 drives the sliding ring 22 to slide horizontally towards the first support ring 21. The sliding ring 22 pulls multiple sets of connecting ropes 235, which in turn pull the rotating pressure plates 233 downwards until the tops of the two sets of rotating pressure plates 233 are tightly pressed and fixed to the top of the tank cover 12. When spring 234 is compressed and the first motor 24 is turned off, the two sets of pressing components 23 reinforce the water seal tank 11 and the cover 12, allowing the water seal tank assembly 1 to continue to be used. When the water seal tank assembly 1 needs to be opened again, the user causes the first motor 24 to drive the threaded rod 25 to rotate. The threaded rod 25 drives the sliding ring 22 to move away from the first support ring 21. At this time, the multiple sets of connecting ropes 235 are relaxed, generating a thrust on the spring 234. The spring 234 pushes the rotating pressure plate 233 at its respective position to lift upwards, thus the two sets of rotating pressure plates 233 stop pressing the cover 12, making it easier for the operator to remove the cover 12 from the top of the water seal tank 11. This clamping and reinforcing design helps prevent material leakage when the water seal tank is tilted or shaken, ensuring the device operates in a stable environment. The device is also easy for the operator to open, facilitating cleaning of the inside of the water seal tank and ensuring the quality of use for the user.

[0045] The device proposed in this invention introduces a pneumatic regulating valve 14 for automatic detection and sewage discharge, reducing the need for manual sludge removal, improving operational efficiency, and reducing labor intensity. The automatic sludge removal design of the device can prevent excessive sludge accumulation, thereby extending the maintenance cycle of the water seal tank assembly 1 and the equipment, and reducing maintenance time. Although the initial investment may increase, in the long run, the automation system can reduce labor costs and lower maintenance and repair expenses, thus reducing the overall operating cost. The automatic detection and sewage discharge system reduces the need for personnel to come into contact with hazardous environments, reducing the risk of device operation. The design takes into account different working conditions and varying sludge deposition rates, enabling the device to adapt to various working environments.
