[0002] The hydraulic mud cannon of blast furnace is one of the key equipment used to block the taphole of blast furnace in the metallurgical industry. In the metallurgical production process, the hydraulic mud cannon needs to withstand the baking of high-temperature molten iron, so its heat resistance and cooling measures are crucial to the normal operation of the equipment.

[0003] At present, the closest existing technical solution is to cool down the hydraulic mud gun manually using a high-pressure water pipe. The operator in front of the furnace uses a high-pressure water pipe to spray water directly onto the hydraulic mud gun in order to prevent overheating and damage to the equipment through rapid cooling.

[0004] Although this manual cooling method has a cooling effect to a certain extent, it has obvious technical defects and problems. First, manual operation requires high water pressure and rapid water pumping in a short period of time, but the high-pressure water column easily causes water splashing and cannot evenly cover the surface of the hydraulic mud gun, resulting in unsatisfactory cooling effect. In addition, manual water pumping not only wastes water resources, but also increases the labor intensity and safety risks of operators. More importantly, due to the lack of automated control, the cooling process cannot achieve timing and cyclic operation, and the stability of the equipment and the continuity of cooling are affected.

[0032] See also Figure 1 The blast furnace mud gun cooling device provided by the embodiment of the utility model includes a support assembly, a spray assembly 10 and a control assembly 20. Among them, the support assembly is arranged on the gun seat 101; the spray assembly 10 is connected to the support assembly, the spray assembly 10 includes a water supply pipe 11 and two spray pipes 12, the two spray pipes 12 are arranged at intervals, the mud gun body 102 is placed between the two spray pipes 12, the water supply pipe 11 is connected to the two spray pipes 12, and the spray pipe 12 is provided with a plurality of water outlets, which are directly opposite to the mud gun body 102; the control assembly 20 includes a power unit, a liquid supply unit and a control valve, the power unit is electrically connected to the liquid supply unit and the control valve, the liquid supply unit is connected to the water supply pipe 11, the control valve is arranged on the water supply pipe 11, and the control valve can control the water supply pipe 11 to be connected or disconnected.

[0033] It is understandable that the blast furnace mud cannon 100 is an existing mechanical device in the art, and the gun mount 101 and the mud cannon body 102 are both conventional components thereof, so the working principle and specific structure thereof are not described in detail herein. Generally speaking, the blast furnace mud cannon 100 is placed horizontally, and for the convenience of description in conjunction with the accompanying drawings, the directions below are described in the directions shown in the accompanying drawings, but are not limited thereto.

[0034] The blast furnace mud cannon cooling device proposed in the utility model makes the installation and maintenance of the equipment easier through the structural design of the spray assembly 10 and the support assembly. The spray pipes 12 are arranged at intervals on both sides of the mud cannon body 102, with a compact structure and small space occupation. Multiple water outlets are evenly distributed on the spray pipes 12 and face the mud cannon body 102, so that the entire surface of the mud cannon body 102 can obtain a uniform spray cooling effect, avoiding the local overheating problem existing in the traditional high-pressure water column cooling method; the control component 20 realizes the automatic control of the spray system by setting the power unit, the liquid supply unit and the control valve and the spray assembly 10. The liquid supply unit can provide a water source for the water supply pipe 11, and the control valve can automatically open or close the water supply pipe 11 as needed, avoiding the inconvenience and inaccuracy of manual operation, and also improving the efficiency and reliability of cooling. In addition, through the spray design and automatic control, the water flow and spray time can be effectively controlled, avoiding the waste of water resources caused by the splashing of high-pressure water columns in the traditional manual water pumping method, and realizing more efficient water resource utilization.

[0035] Specifically, the power unit includes a power box 23, a drive motor and a control console 22. The power box 23 is used to provide the required power to drive the operation of the cooling system. The control console 22 and the drive motor are electrically connected to the liquid supply unit and the control valve through cables. The operator controls each device through the control console 22 to ensure the coordinated operation of each part of the system. The liquid supply unit includes a water tank and a water pump for storing and transporting cooling water. The water tank is used to store the water source required for cooling, and the water pump transports water from the water tank to the water supply pipe 11 through a pipeline. The design of the liquid supply unit ensures sufficient supply and stable pressure of cooling water. In addition, in this embodiment, the control valve is a solenoid valve 21, which includes a solenoid coil and a movable valve core. When the solenoid coil is energized, a magnetic field is generated to drive the valve core to move to realize the opening and closing control of the valve. The solenoid valve 21 has a simple structure and a fast response speed, and is suitable for an automatic control system. In other embodiments, the control valve can also be a universal valve, a flow valve, etc., which is not limited here. When in use, the operator sends an electrical signal to the solenoid valve 21 through the control console 22, and the solenoid valve 21 is powered on and opened, so that the cooling water enters the spray pipe 12 through the water supply pipe 11, and is sprayed from the multiple water outlets on the spray pipe 12 onto the mud gun body 102, thereby achieving a cooling effect. It can be understood that the power box 23, the drive motor, the control console 22 and the solenoid valve 21 are all existing electrical equipment, and their specific structures and working principles are not described in detail here.

[0036] Regarding the spray assembly 10, specifically, the spray assembly 10 also includes a connecting pipe 13, which is T-shaped and has three connecting ends formed on the connecting pipe 13, and the water supply pipe 11 and the two spray pipes 12 are each connected to one connecting end. The design of the T-shaped connecting pipe 13 ensures that the water supply pipe 11 can evenly supply water to the two spray pipes 12, effectively avoiding the problem of uneven water flow distribution, thereby ensuring that the water output of each water outlet on the spray pipe 12 is consistent; in addition, the T-shaped connecting pipe 13 simplifies the connection structure of the water supply pipe 11 and the spray pipe 12, and the water supply pipe 11 and the two spray pipes 12 can be quickly connected through only three connecting ends, which reduces the installation steps, improves the installation efficiency, and is also convenient for later maintenance and replacement.

[0037] More specifically, the spray assembly 10 further includes a metal hose 14, one end of which is connected to the water supply pipe 11, and the other end of the metal hose 14 is connected to the connection end. On the one hand, the metal hose 14 has high flexibility and can be flexibly bent and adjusted, making the spray assembly 10 more convenient during installation and adapting to different installation environments and space requirements. The metal hose 14 can effectively absorb and buffer water flow impact and equipment vibration, reduce the impact force on the water supply pipe 11 and the connection pipe 13, and extend the service life of the pipeline system; on the other hand, the metal hose 14 has excellent high temperature resistance and can maintain good physical properties under high temperature conditions in the blast furnace working environment, preventing the hose from aging, deformation or rupture due to high temperature, thereby ensuring the long-term reliable operation of the spray system.

[0038] In order to ensure the sealing of the spray assembly 10, a sealing ring is provided at the connection between the spray pipe 12 and the water supply pipe 11. The sealing ring can effectively prevent the system pressure from being unstable due to water leakage at the connection, ensure the safe operation of the spray system under high pressure, and avoid equipment failure or safety hazards caused by water leakage. In addition, the use of the sealing ring reduces the wear and corrosion of the connection, prolongs the service life of the water supply pipe 11 and the spray pipe 12, reduces the maintenance and replacement frequency, and thus improves the durability and economy of the entire device. In this embodiment, the sealing ring uses an existing rubber sealing ring. In other embodiments, a metal sealing ring may also be used, which is not limited here.

[0039] During the spraying process of the spray pipe 12 on the mud gun body 102, according to different working conditions and different temperatures of the mud gun body 102, the amount of water required to be sprayed by the spray pipe 12 is also different. Too much water will cause waste of water resources, and too little water may not achieve the cooling effect. Therefore, a flow regulating valve is provided on the spray pipe 12, and the flow regulating valve can adjust the flow size in the spray pipe 12, so as to accurately adjust the water volume in the spray pipe 12 according to actual needs, and ensure that the amount of water sprayed under different working conditions and temperature conditions is just right, which can achieve effective cooling and avoid water resource waste. By adjusting the flow in real time, it can be ensured that the spray system is always in the best working state, and the spray intensity can be quickly adjusted according to the temperature change of the mud gun body 102, so as to improve the cooling effect and efficiency, and ensure the stable operation of the equipment in a high temperature environment. Specifically, the flow regulating valve includes a valve body and a valve core. The flow regulating valve is installed at the connection between the spray pipe 12 and the water supply pipe 11 to ensure that the regulated water flow can directly enter the spray pipe 12. The control component 20 is electrically connected to the valve core. The position of the valve core can be automatically adjusted through the control component 20 to achieve precise flow control. It can be understood that the flow regulating valve uses an existing regulating valve, and its working principle and specific structure are not described in detail here.

[0040] Furthermore, a nozzle is provided corresponding to each water outlet, and the nozzle is detachably connected to the spray pipe 12. The nozzle can accurately direct the water flow to the part that needs to be cooled, enhance the spraying effect, achieve uniform and concentrated water flow distribution, and improve the cooling efficiency. The detachable connection makes the installation and adjustment of the nozzle more convenient. According to different working conditions, the angle and position of the nozzle can be easily replaced or adjusted to ensure the best spray coverage and cooling effect. In this embodiment, the nozzle is snap-fitted to the water outlet of the spray pipe 12 for easy operation and disassembly; in other embodiments, the nozzle can also be set to a bolt connection, a pin connection, etc. In addition, regarding the shape of the nozzle, different types and specifications of nozzles can be selected according to the cooling requirements, such as fan nozzles, conical nozzles, etc., to achieve different spray modes and water flow forms to meet a variety of cooling requirements, which are not limited here.

[0041] Since the height orientation of the mud cannon main body 102 of different blast furnace mud cannons 100 is different, and the installation position of the device during the on-site construction process also needs to be adjusted according to the actual working conditions, in order to improve adaptability and practicality, the support assembly includes a lifting platform, which extends in the vertical direction. The lifting platform includes a plurality of platforms that are coaxially set one after another, and one of the two adjacent platforms can be locked in another platform, and the spray assembly 10 is detachably connected to the top platform. The design of the lifting platform can be flexibly adjusted according to the height and position of the main body of different blast furnace mud cannons 100, ensuring that the spray assembly 10 is always in the best spray angle and height, and improving the adaptability of the device to different working conditions. Through the multi-stage platform design of the lifting platform, accurate height adjustment can be achieved, so that the spray assembly 10 can be accurately positioned to the part of the mud cannon main body 102 that needs to be cooled, ensuring the best cooling effect. The platforms of the lifting platform can be locked with each other, ensuring that they can be stably fixed after being adjusted to a suitable height, avoiding the displacement of the spray assembly 10 due to vibration or other factors, and ensuring the continuity and stability of the cooling process.

[0042] Furthermore, a rotating base is provided at the bottom of the support assembly, and the rotating base can rotate around the axis of the gun mount 101. The rotating base can rotate around the axis of the gun mount 101, so that the spray assembly 10 can flexibly adjust the spray angle, ensuring that the cooling water flow can accurately cover different parts of the mud gun body 102, and improving the uniformity and comprehensiveness of the cooling effect. Operators can easily adjust the angle of the spray assembly 10 by rotating the base according to the on-site working conditions and cooling requirements, without frequently moving the entire device, making the operation more convenient and quick, and improving work efficiency

[0043] In addition, the blast furnace mud cannon cooling device also includes a temperature sensor, which is arranged on the support assembly, and the detection end of the temperature sensor is facing the mud cannon body 102. When the temperature of the mud cannon body 102 is lower than the first set value, the temperature sensor can generate a prompt message. The first set value can be customized according to the actual needs of the site, and will not be repeated here. The temperature sensor can change according to the temperature of the mud cannon body 102. When the temperature of the mud cannon body 102 is reduced to a suitable temperature, the temperature sensor generates a corresponding prompt message to remind the operator to stop or adjust the cooling water volume in time, avoid unnecessary waste of water resources, achieve efficient use of water resources, and improve the economy and environmental protection of the cooling system. Through the real-time monitoring and prompting functions of the temperature sensor, the dependence on manual inspection and operation is reduced, the frequency and intensity of manual operation are reduced, the work efficiency is improved, and the possibility of human error operation is reduced. It can be understood that the temperature sensor uses an existing infrared temperature sensing device, and its specific structure and working principle are not repeated here.

[0044] The blast furnace mud gun cooling device provided by the utility model embodiment has the following specific operating steps:

[0045] When the temperature of the mud gun body 102 rises and reaches the set temperature value, the temperature sensor detects the temperature change and transmits the signal to the control console 22. After the control console 22 receives the signal, the operator drives the water pump through the control console 22 to extract water from the water tank and transports the water to the water supply pipe 11 through the liquid supply part. At the same time, the control console 22 sends an electrical signal to the solenoid valve 21, and the solenoid valve 21 is powered on and opened, so that the cooling water enters the spray pipe 12 through the water supply pipe 11, and is sprayed onto the mud gun body 102 from the nozzles of the multiple water outlets on the spray pipe 12, achieving a cooling effect.

[0046] When the temperature of the mud gun body 102 drops and is lower than the set temperature value, the temperature sensor detects the temperature change again and transmits the signal to the control system. After the console 22 receives the signal, the operator closes the solenoid valve 21 through the console 22, the solenoid valve 21 is powered off and closed, and the supply of cooling water is stopped at the same time, and the whole cooling process ends.

[0047] The above embodiments are only to illustrate the basic principles and characteristics of the present invention. The present invention is not limited by the above embodiments. Without departing from the spirit and scope of the present invention, the present invention may be subject to various changes and modifications, which are within the scope of the present invention.
