Description

Technical Field

[0001] This invention relates to the field of hydraulic mud gun technology, specifically to a novel hydraulic mud gun with visualized mud output and its working principle. Background Technology

[0002] Hydraulic mud guns are key equipment in the blast furnace ironmaking process of the metallurgical industry, mainly used for sealing the blast furnace taphole. Their operational stability and mud-pumping accuracy directly affect the normal operation and production efficiency of the blast furnace. With the continuous development of the metallurgical industry, the demand for domestic replacement of hydraulic mud guns is becoming increasingly urgent. However, existing domestic hydraulic mud guns still have many technical shortcomings and cannot meet the requirements of efficient and precise production.

[0003] First, existing hydraulic mud gun attitude adjustment mechanisms mostly use a single transmission structure, which suffers from unstable power transmission and low adjustment accuracy. Some devices use gear or chain transmission to adjust the mud gun tube's attitude, which is prone to excessive transmission clearance and severe wear, causing the mud gun tube to be unable to accurately align with the taphole and affecting the sealing effect. At the same time, the lack of an effective linkage guide structure during the adjustment process makes the mud gun tube prone to deviation, increasing operational risks.

[0004] Secondly, the lack of effective monitoring methods for mud discharge is a core weakness of existing equipment. Traditional hydraulic mud cannons rely heavily on operators' experience to judge the amount of mud to be discharged, lacking real-time and accurate monitoring devices. This easily leads to problems such as insufficient mud discharge resulting in incomplete sealing, or excessive mud discharge causing mud waste and excessive equipment load. The few devices equipped with monitoring functions mostly use single flow rate or stroke monitoring methods, resulting in limited data, low accuracy, and the inability to visualize the data, making it difficult for operators to quickly obtain accurate mud discharge information. Summary of the Invention

[0005] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a novel hydraulic mud gun with visualized mud volume, which can effectively solve the problems in the existing technology.

[0006] This invention provides a novel hydraulic mud gun with visualized mud output, comprising an adjustment structure, a mud gun structure, and a display structure disposed between the adjustment structure and the mud gun structure. The adjustment structure includes two sets of base frames, a fixed seat and a deflection seat disposed on the top base frame, a deflection arm disposed on the deflection seat, and a support arm fixed to the end of the deflection arm. The top of the fixed seat is fixedly connected to a mounting plate in the display structure. The mud gun structure includes a mud gun pipe and a connecting arm fixed to the outer wall of the mud gun pipe. The bottom end of the connecting arm is fixedly connected to a connecting plate. The middle part of the connecting plate is rotatably disposed in the fixed seat via a fixed shaft. The display structure includes an arrow fixed to the top of the mounting plate and a display panel opened on the top of the connecting plate. A hydraulic telescopic rod is disposed at the tail end of the mud gun pipe, a plug fixed to the top of the rod, and a flow meter is fixed at the outlet end of the mud gun pipe.

[0007] Furthermore, a set of positioning blocks is fixed between the bottom of the mounting plate and the base frame, and in the middle of the deflection arm. The positioning blocks have round holes opened laterally. The upper and lower ends of the positioning blocks are fixedly connected to the mounting plate, the base frame and the deflection arm. A drive rod is fixed inside the two sets of positioning blocks, and the drive rod is connected to the external power equipment for transmission.

[0008] Furthermore, a circular hole is provided in the middle of one end of the drive rod, and a single-sided trunnion is provided on the top cover of the circular hole. The slot in the middle of each group of positioning blocks is a threaded slot structure, and the threads in the two groups of positioning blocks are opposite in direction. A threaded slot structure is provided on the outer side of the drive rod, and it is engaged with the two groups of positioning blocks.

[0009] Furthermore, the front end of the mounting plate is provided with a circular groove whose size is adapted to the outer diameter of the connecting plate.

[0010] Furthermore, a control device is provided on the outside of the mud cannon structure, and a control motherboard is provided inside the control device. The control motherboard is electrically connected to the flow meter and the hydraulic telescopic rod through an encoder module, and a display screen is provided on the control device.

[0011] Furthermore, a retaining ring is provided inside the mud gun tube, and the middle part of the hydraulic telescopic rod passes through the retaining ring and is connected and fixed to the plug.

[0012] Furthermore, the hydraulic telescopic rod has two inner retaining rings inside, and the outer side of each inner retaining ring contacts the inner sidewall through a square ring. The square ring is composed of a guide ring and a sealing and wear-resistant material. The sealing and wear-resistant material is a combination structure of a polytetrafluoroethylene (PTFE) ring and a rectangular rubber sealing ring, and this structure is fixed to the inner side of the metal guide ring.

[0013] Furthermore, the base frame at the top is inclined to the ground, the inner side of the mud gun tube is higher than the outer side, and the end of the mud gun tube has a downward inclined structure.

[0014] This invention also provides a novel hydraulic mud cannon with visualized mud volume operation, which is used to realize the hydraulic mud bubble structure. Step 1: ① An external power unit drives the drive rod to rotate via a single-sided trunnion. The trunnion fits into a round hole at one end of the drive rod, ensuring stable power transmission. The threaded groove on the outside of the drive rod meshes with the threaded grooves in two sets of positioning blocks, and the threads of the two sets of positioning blocks rotate in opposite directions, providing a basis for power conversion for attitude adjustment. ② According to the principle of threaded transmission, the rotation of the drive rod is converted into the relative approaching or moving away movement of the two sets of positioning blocks along the axial direction of the drive rod. One set of positioning blocks is fixed in the middle of the deflection arm, and its axial movement drives the deflection arm to deflect around the deflection seat, which in turn pulls the connecting plate around the fixed axis through the support arm at the end of the deflection arm. ③ The connecting plate is fixed to the connecting arm on the outer wall of the mud gun tube. The rotation of the connecting plate directly drives the mud gun tube to adjust its attitude. At the same time, the inclined design of the top frame, combined with the structure of the mud gun tube with the inner side higher than the outer side and the end tilted downward, provides a reasonable initial angle for mud-driving operations, completing attitude adjustment. Step Two: ① After the mud gun barrel is adjusted to the correct position, the hydraulic telescopic rod is activated. The plug fixed at its top moves axially along the inside of the mud gun barrel as the hydraulic telescopic rod extends and retracts. The plug generates a stable thrust on the mud inside the barrel, providing the core power for mud-pulling operations. ② The retaining ring inside the mud gun barrel provides precise guidance and limit for the hydraulic telescopic rod, preventing it from deviating during movement and ensuring the stability of the plug's mud-pushing trajectory, thus ensuring mud-pulling efficiency. ③ The two inner retaining rings inside the hydraulic telescopic rod work in conjunction with the square ring. Step 3: ① During the mud-making process, the angle of the mud gun pipe changes slightly as the connecting plate rotates around the fixed axis, and the display panel at the top of the connecting plate rotates synchronously; the arrow at the top of the mounting plate points to the scale markings on the display panel, intuitively presenting preliminary information on the mud-making amount related to the mud-making posture, achieving visual judgment at the mechanical level; ② The flow meter at the outlet of the mud gun pipe collects the mud output flow data in real time, and the control mainboard in the control equipment simultaneously collects the extension and retraction stroke data of the hydraulic telescopic rod through the encoder module, forming a dual data acquisition dimension; ③ The control mainboard integrates and processes the flow meter flow data and the hydraulic telescopic rod stroke data, displaying the precise mud-making amount information on the display screen of the control equipment, providing operators with intuitive and accurate operational references, and completing the accurate monitoring and visualization of the mud-making amount.

[0015] Compared with existing technologies, the beneficial effects of this invention are as follows: It employs a dual sludge volume monitoring structure combining mechanical visualization and precise electronic monitoring. On one hand, the display panel at the top of the connecting plate works in conjunction with the arrow at the top of the mounting plate. Subtle changes in the angle of the sludge cannon during sludge production cause the display panel to rotate synchronously, and the scale indicated by the arrow visually presents preliminary information on the sludge volume, achieving real-time visual judgment at the mechanical level. On the other hand, the flow meter at the outlet of the sludge cannon collects real-time sludge output flow data, and the control board simultaneously collects the extension and retraction stroke data of the hydraulic telescopic rod through the encoder module. After integrating and processing the two sets of data, precise sludge volume information is displayed on the control device's screen. This complementary dual monitoring method effectively solves the problems of traditional equipment relying on experience for sludge volume judgment and low monitoring accuracy. Operators can quickly obtain accurate sludge volume information, precisely control the sludge volume, avoid sludge waste and incomplete sealing, and improve operational accuracy. In this device, the equipment adopts a linkage transmission structure of "single-sided trunnion + bidirectional threaded drive rod + double positioning block". The external power equipment is precisely matched with the drive rod through the single-sided trunnion to ensure the stability of power transmission. The outer thread of the drive rod meshes with the threads of two sets of positioning blocks with opposite rotation directions, which accurately converts the rotation of the drive rod into the axial relative movement of the positioning blocks, thereby driving the deflection arm, support arm and connecting plate to move together and realize the precise adjustment of the mud gun tube posture.

All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0020] The present invention will be further described below with reference to embodiments.

[0021] Example: A novel hydraulic mud gun with visualized mud output, see attached document. Figure 1 - Appendix Figure 9 The system includes an adjustment structure 1, a mud gun structure 2, and a display structure 3 located between the adjustment structure 1 and the mud gun structure 2. The adjustment structure 1 includes two sets of base frames 11, a fixed seat 12 and a deflection seat 17 located on the top base frame 11. A deflection arm 14 is provided on the deflection seat 17, and a support arm 13 is fixed to the end of the deflection arm 14. The top of the fixed seat 12 is fixedly connected to the mounting plate 33 in the display structure 3. The mud gun structure 2 includes a mud gun tube 21 and a connecting arm 22 fixed to the outer wall of the mud gun tube 21. The bottom end of the connecting arm 22 is fixedly connected to the connecting plate 23. The middle part of the connecting plate 23 is rotatably mounted in the fixed seat 12 through a fixed shaft 24. The display structure 3 includes an arrow 32 fixed to the top of the mounting plate 33 and a display panel 31 opened at the top of the connecting plate 23. The tail end of the mud gun pipe 21 is equipped with a hydraulic telescopic rod 25 and a plug 26 fixed to the top of the rod, and a flow meter 27 is fixed at the outlet end of the mud gun pipe 21. This equipment integrates the adjustment structure 1, the mud gun structure 2 and the display structure 3. The various structures are precisely connected by components such as the fixing seat 12, the mounting plate 33, and the connecting plate 23. The overall structure is compact, occupies little space, and is easy to install and arrange in the complex environment around the blast furnace. At the same time, the connection method of each core component is simple and reliable. The fixed connection design between the positioning block 16 and the mounting plate 33, the base frame 11 and the deflection arm 14 facilitates the disassembly and maintenance of the equipment and reduces the workload of maintenance personnel.

[0022] A set of positioning blocks 16 are fixed between the bottom of the mounting plate 33 and the base frame 11, and in the middle of the deflection arm 14. The positioning blocks 16 have round holes opened laterally. The upper and lower ends of the positioning blocks 16 are fixedly connected to the mounting plate 33, the base frame 11 and the deflection arm 14. A drive rod 15 is fixed inside the two sets of positioning blocks 16. The drive rod 15 is connected to the external power equipment. A round groove is opened at the front end of the mounting plate 33. Its size is adapted to the outer diameter of the connecting plate 23. The top base frame 11 is set at an inclination to the ground, and the inner side of the mud gun pipe 21 is higher than the outer side. The end of the mud gun pipe 21 has a downward inclined structure.

[0023] A circular hole is provided in the middle of one end of the drive rod 15, and a single-sided trunnion 151 is placed inside the hole. The trunnion is fitted with an alloy copper sleeve to prevent damage to the cylinder spherical bearings caused by poor lubrication. This also better suits the installation and use conditions of the new rotary arm. The trunnion sleeve is made of chromium-zirconium copper (CuCrZr), which exhibits high strength and hardness at both room temperature and high temperature (400℃), as well as good electrical and thermal conductivity and wear resistance. The slots in the middle of each set of positioning blocks 16 are threaded grooves, and the threads in the two sets of positioning blocks 16 rotate in opposite directions. A threaded groove is provided on the outer side of the drive rod 15, engaging with the two sets of positioning blocks 16. The structure is: "Single-sided trunnion 151 + bidirectional threaded drive rod 15 + double positioning blocks 16". The linkage transmission structure allows for precise matching between the external power equipment and the drive rod 15 via a single-sided trunnion 151, ensuring stable power transmission. The outer thread of the drive rod 15 engages with two sets of oppositely rotating positioning blocks 16, accurately converting the rotation of the drive rod 15 into the relative axial movement of the positioning blocks 16. This, in turn, drives the deflection arm 14, the support arm 13, and the connecting plate 23 in a coordinated manner, achieving precise adjustment of the mud gun tube 21's posture. Simultaneously, the inclined design of the top base frame 11, combined with the structure of the mud gun tube 21 where the inner side is higher than the outer side and the end is inclined downwards, provides a reasonable initial angle for mud-driving operations, reduces mud flow resistance, and further improves the reliability of the sealing operation. Compared to traditional transmission structures, this solution effectively reduces transmission clearance, decreases equipment wear, and significantly improves posture adjustment accuracy.

[0024] A control device is installed on the outside of the mud gun structure 2, and a control main board is installed inside the control device. The control main board is electrically connected to the flow meter 27 and the hydraulic telescopic rod 25 through the encoder module, and a display screen is installed on the control device. A retaining ring 28 is installed inside the mud gun tube 21, and the middle of the hydraulic telescopic rod 25 passes through the retaining ring 28 and is connected and fixed to the plug head 26. A dual mud-discharge monitoring structure combining mechanical visualization and electronic precision monitoring is set up: On the one hand, through the cooperation of the display disk 31 at the top of the connecting plate 23 and the arrow 32 at the top of the mounting plate 33, the slight change in the angle of the mud gun tube 21 during mud discharging drives the display disk 31 to rotate synchronously. The scale pointed to by the arrow 32 can intuitively present the preliminary information of mud discharging, realizing real-time visualization judgment at the mechanical level; on the other hand, the flow meter 27 at the outlet end of the mud gun tube 21 collects the mud output flow data in real time, and the control main board collects the extension stroke data of the hydraulic telescopic rod 25 synchronously through the encoder module. After integrating and processing the two sets of data, the accurate mud discharging information is displayed on the display screen of the control device. The dual monitoring methods complement each other, effectively solving the problems of traditional equipment relying on experience to judge the amount of mud being pumped and low monitoring accuracy. Operators can quickly obtain accurate mud pumping information, accurately control the amount of mud being pumped, avoid problems such as mud waste and incomplete sealing, and improve the accuracy of operation.

[0025] The hydraulic telescopic rod 25 has two inner retaining rings 252 inside, and the outer side of each inner retaining ring 252 contacts the inner wall through a square ring 251. The square ring 251 is composed of a guide ring and a sealing and wear-resistant material. The sealing and wear-resistant material is a combination of a polytetrafluoroethylene (PTFE) ring and a rectangular rubber sealing ring, and this structure is fixed to the inner side of the metal guide ring. Multiple guiding and sealing structures are set in the transmission path of the hydraulic telescopic rod 25: the retaining ring 28 inside the mud gun pipe 21 plays a precise guiding and limiting role for the hydraulic telescopic rod 25, preventing it from deviating during movement; the two inner retaining rings 252 inside the hydraulic telescopic rod 25, together with the square ring 251 (the combination of a guide ring, a PTFE ring, and a rectangular rubber sealing ring), not only enhance the guiding accuracy of the telescopic movement, but also achieve excellent sealing performance, effectively reducing the risk of hydraulic oil leakage, and reducing wear during movement. This structural design significantly improves the stability and durability of the hydraulic transmission system, extends the equipment's service life, and reduces maintenance costs. Core structures such as the adjustment mechanism 1, mud gun mechanism 2, and monitoring and display mechanism are all locally developed and manufactured, eliminating reliance on imported equipment. Compared to imported hydraulic mud guns, this equipment not only has significantly lower production costs but also offers convenient parts procurement and lower technical barriers to maintenance, effectively reducing equipment investment and operating costs for metallurgical enterprises. It possesses excellent market promotion value and promising industry application prospects.

[0026] Example 2: The working principle of a novel hydraulic mud cannon with visualized mud output, used to implement the hydraulic mud bubble structure in Example 1. Step 1: ① An external power device drives the drive rod 15 to rotate via a single-sided trunnion 151. The single-sided trunnion 151 is fitted with a round hole at one end of the drive rod 15 to ensure the stability of power transmission. The threaded groove on the outside of the drive rod 15 meshes with the threaded grooves in the two sets of positioning blocks 16, and the threads of the two sets of positioning blocks 16 rotate in opposite directions, providing a basis for the power conversion of attitude adjustment. ② According to the principle of threaded transmission, the rotation of the drive rod 15 is converted into the relative approaching or moving away movement of the two sets of positioning blocks 16 along the axial direction of the drive rod 15. One set of positioning blocks... Block 16 is fixed to the middle of the deflection arm 14. Its axial movement causes the deflection arm 14 to deflect around the deflection seat 17, and then the connecting plate 23 is pulled to rotate around the fixed axis 24 through the support arm 13 at the end of the deflection arm 14; ③: The connecting plate 23 is fixed to the connecting arm 22 on the outer wall of the mud gun tube 21. The rotation of the connecting plate 23 directly drives the mud gun tube 21 to adjust its posture; at the same time, the inclined design of the top base frame 11, combined with the structure of the mud gun tube 21 with the inner side higher than the outer side and the end tilted downward, provides a reasonable initial angle for mud-driving operation and completes the posture adjustment; Step Two: ① After the mud gun tube 21 is adjusted to the correct position, the hydraulic telescopic rod 25 is activated. The plug 26 fixed at its top moves axially along the inside of the mud gun tube 21 as the hydraulic telescopic rod 25 extends and retracts. The plug 26 generates a stable thrust on the mud inside the tube, providing the core power for mud-pulling operations. ② The retaining ring 28 inside the mud gun tube 21 provides precise guidance and limit for the hydraulic telescopic rod 25, preventing the hydraulic telescopic rod 25 from deviating during its movement, ensuring the stability of the plug 26's mud-pushing trajectory, and ensuring mud-pulling efficiency. ③ The two inner retaining rings 252 inside the hydraulic telescopic rod 25 cooperate with the square ring 251. Step 3: ① During the mud-making process, the angle of the mud-pump pipe 21 changes slightly as the connecting plate 23 rotates around the fixed shaft 24, and the display disk 31 at the top of the connecting plate 23 rotates synchronously; the arrow 32 at the top of the mounting plate 33 points to the scale markings on the display disk 31, intuitively presenting the preliminary information on the mud-making amount related to the mud-making posture, realizing a visual judgment at the mechanical level; ② The flow meter 27 at the outlet end of the mud-pump pipe 21 collects the mud output flow data in real time, and the control main board in the control equipment collects the extension stroke data of the hydraulic telescopic rod 25 through the encoder module, forming a dual data acquisition dimension; ③ The control main board integrates and processes the flow data of the flow meter 27 and the stroke data of the hydraulic telescopic rod 25, and displays the accurate mud-making amount information on the display screen of the control equipment, providing operators with an intuitive and accurate operational reference, and completing the accurate monitoring and visualization of the mud-making amount.

The control board in the control equipment collects the extension stroke data of the hydraulic telescopic rod (25) through the encoder module, forming a dual data acquisition dimension. ③: The control board integrates and processes the flow data of the flow meter (27) and the stroke data of the hydraulic telescopic rod (25), and displays the accurate mud-dispensing information on the display screen of the control equipment, providing operators with intuitive and accurate operation references, and completing the accurate monitoring and visualization of mud-dispensing volume.
