Description

Technical Field

[0001] The invention belongs to the technical field of drainage device structures, and relates to a drainage tube and a hanging drainage device based on the drainage tube. Background Art

[0002] In the industrial production process, especially in the process of high-temperature liquid slag treatment, such as steel smelting, non-ferrous metal smelting and other industries, the treatment of liquid slag has always been a key technology. Liquid slag not only has high temperature, but also has strong fluidity and easy splashing, which brings great challenges to safe treatment and resource recovery. Traditional treatment methods often have problems such as low efficiency, environmental pollution and safety hazards. Under specific production conditions, such as when the slag liquid temperature is stable at around 1360℃, it is in a vertical flow state and there is no coke hanging phenomenon, the drainage treatment of liquid slag becomes an efficient and environmentally friendly solution. However, to achieve this solution, a series of technical difficulties must be overcome. First, there are many potential problems in the direct drainage of liquid slag, such as splashing and blockage during the drainage process, and the high temperature resistance of the drainage trough. These problems need to be properly solved through rigorous experimental verification and technical improvement. Secondly, during the drainage process, the high-temperature liquid slag will be affected by the super-strong convection of the high-temperature gas field and the cold air. This influence may cause the stagnation and blockage of the drainage trough, thereby affecting the stability and efficiency of the drainage. In addition, the choice of drainage angle has an important influence on the success and flow rate of drainage. Different drainage angles will cause the flow state of the liquid slag in the drainage trough to change, thus affecting the drainage effect. Therefore, it is necessary to explore the optimal drainage angle range under actual conditions through experiments. At the same time, the reasonable location selection of the drainage access point is also a key technology. The location of the access point directly affects the drainage effect and collection efficiency of the liquid slag. Therefore, it is necessary to explore a scientific and reasonable access point selection method.

[0003] In summary, the development and application of hoisting drainage devices is one of the key technologies to solve the problem of high-temperature liquid slag treatment, but the existing drainage devices are not ideal in solving the above problems. Summary of the invention

[0004] The purpose of the present invention is to solve the technical problem that the drainage effect of the drainage device for high-temperature liquid fluid in the prior art is poor, and to provide a drainage pipe and a hoisting drainage device based on the drainage pipe.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions: In a first aspect, the present invention discloses a drainage tube, comprising an inner lining tube and an outer tube which are sleeved and tightly fitted; the material of the inner lining tube is mullite; the material of the outer tube is stainless steel or a ceramic composite material.

[0006] Further improvements are: The wall thickness of the inner liner pipe is 2 mm-3 mm.

[0007] The outer tube is an S310 tube or a silicon carbide + silicon nitride composite sintered tube.

[0008] The outer wall of the outer tube is wrapped with a thermal insulation material; the thermal insulation material is an aerogel foam ceramic thermal insulation felt.

[0009] The inlet of the drainage tube is provided with a throat; the throat is a circular arc groove structure.

[0010] In the second aspect, the present invention discloses a hanging drainage device based on the above-mentioned drainage pipe, including a hanger, a wheel group is arranged on the upper part of the hanger, and the wheel group is movably connected with a hanging rope; one end of the hanging rope is connected to a front hanging point device, and the other end is connected to a rear hanging point device; the front hanging point device and the rear hanging point device are respectively located on both sides of the hanger; the drainage pipe is installed on the front hanging point device and the rear hanging point device; one end of the drainage pipe is provided with a throat and extends into a high-temperature device to be drained, and the other end is arranged above the drainage collection device.

[0011] Further improvements are: The front hanging point device and the rear hanging point device are both provided with locking clamps for locking the drainage tube.

[0012] A windshield door is sleeved at the junction of the portion of the drainage pipe extending into the high-temperature device and the portion located outside, and a quartz observation window is arranged on the windshield door.

[0013] The hanger comprises a steel beam, and hanger uprights are fixedly connected at both ends of the steel beam; the hanger uprights at both ends of the steel beam are relatively provided with slots, and the optical axis and the two ends of the pressure rod are supported in the slots; the drainage tube is located between the optical axis and the pressure rod.

[0014] The wheel set is connected to a motor, and the motor is connected to a control system.

[0015] Compared with the prior art, the present invention has the following beneficial effects: The invention discloses a drainage pipe, which uses mullite as the inner lining material. Mullite has extremely high high temperature resistance and good thermal shock resistance, and can withstand the high temperature of liquid slag without being easily deformed or broken. At the same time, the outer pipe uses a stainless steel pipe or a ceramic composite material, which further enhances the overall high temperature resistance and wear resistance, and effectively prolongs the service life of the drainage pipe. In addition, the drainage pipe forms a smooth drainage channel, which reduces the splashing phenomenon of liquid slag during the drainage process. In addition, the inner lining pipe of the mullite material has good scouring resistance, which can effectively prevent the solid particles in the liquid slag from clogging the pipeline during the drainage process, thereby ensuring the stability and continuity of the drainage. Through reasonable drainage pipe design, especially the close fit between the inner lining pipe and the outer pipe, and the excellent performance of the mullite material, the drainage pipe can better adapt to the flow characteristics of high-temperature liquid slag during the drainage process. At the same time, by adjusting the drainage angle and the access point position, the drainage effect can be further optimized and the collection efficiency of the liquid slag can be improved. The present invention successfully solves key technical problems such as splashing, clogging and high temperature resistance of the drainage trough during the drainage of high-temperature liquid slag. At the same time, the influence of the high-temperature gas field and the super-strong convection of cold air on the drainage process is also considered. By optimizing the drainage pipe material and structure, the stability and efficiency of the drainage are improved. The drainage pipe design of the present invention not only improves the processing efficiency of liquid slag, but also reduces environmental pollution and energy consumption. By optimizing the drainage process, the splashing and leakage of liquid slag are reduced, and the pollution to the environment is reduced. At the same time, the use of thermal insulation materials also reduces heat loss and improves energy utilization efficiency.

[0016] Furthermore, the outer tube of the drainage tube adopts S310 tube or silicon carbide + silicon nitride composite sintered tube. Both materials have good high temperature resistance and can withstand the high temperature of liquid slag without being easily deformed or damaged, thereby ensuring the stability and safety of the drainage process.

[0017] Furthermore, the outer wall of the outer tube is wrapped with aerogel foam ceramic insulation felt. This insulation material has extremely low thermal conductivity and excellent thermal insulation performance, which can effectively reduce heat loss, lower the temperature around the drainage tube, and further improve the safety and energy efficiency of the drainage process.

[0018] Furthermore, the inlet of the drainage pipe is provided with a throat of a circular arc groove structure, which can guide the liquid slag to enter the drainage pipe more smoothly, reducing the risk of splashing and clogging. At the same time, the circular arc groove structure can also buffer and disperse the liquid slag to a certain extent, making it more evenly distributed in the drainage pipe, thereby improving the drainage effect and collection efficiency.

[0019] The present invention discloses a lifting drainage device based on a drainage pipe. The lifting drainage device adopts a hanger and a wheel group design, so that the drainage pipe can be flexibly moved and adjusted while maintaining balance. The setting of the wheel group reduces the friction resistance, which is convenient for the rapid response and positioning of the drainage pipe in a high temperature environment. The front hanging point device and the rear hanging point device are respectively located on both sides of the hanger, providing stable support for the drainage pipe, effectively preventing the deformation or falling off of the drainage pipe caused by the gravity of the high-temperature liquid slag, and ensuring the safety and stability of the drainage process. The throat provided on the drainage pipe can accurately guide the high-temperature liquid slag into the drainage pipe, reducing the risk of splashing and leakage, and improving the drainage efficiency. The design of the lifting drainage device enables the drainage pipe to be easily extended into the high-temperature device to be drained, and the other end is accurately set above the drainage collection device, ensuring that the liquid slag can flow smoothly into the collection device, avoiding the waste of resources and environmental pollution. The structural design of the lifting drainage device is reasonable and can meet the treatment needs of high-temperature liquid slag of different scales and types. By adjusting the length and angle of the suspension rope, the position and posture of the drainage tube can be flexibly adjusted to adapt to different working environments and conditions. The operation is simple and easy, reducing the skill requirements for operators. The design of components such as the hanger, wheel set and suspension rope makes the lifting process more intuitive and easy to control, reducing the risk of human operating errors.

[0020] Furthermore, the windshield installed at the junction of the part of the drainage pipe extending into the high-temperature device and the part located outside can effectively isolate the convection of high-temperature airflow and cold air, reducing the risk of obstruction and blockage during the drainage process. At the same time, the quartz observation window set on the windshield allows the operator to observe the drainage status without direct contact with the high-temperature environment, ensuring the smooth progress of the drainage process.

[0021] Furthermore, the hanger adopts a stable support structure composed of steel beams and hanger uprights, and supports the optical axis and the pressure rod through the slot to stably clamp the drainage tube in the middle. This design not only improves the stability of the drainage tube, but also facilitates the adjustment of the position and angle of the drainage tube to adapt to different working environments and conditions.

[0022] Furthermore, the wheel set is connected to the motor and is automatically controlled through the control system. This enables the lifting drainage device to quickly and accurately adjust the position and posture of the drainage tube as needed, thereby improving operational efficiency. At the same time, automated control also reduces the skill requirements for operators and reduces the risk of human operational errors. BRIEF DESCRIPTION OF THE DRAWINGS
