Description

Technical Field

[0001] This application relates to the field of furnace and kiln repair technology, and in particular to a furnace and kiln repair system and repair method. Background Technology

[0002] In industrial production, especially in core industrial enterprises such as coking and chemical industries, industrial furnaces are widely used as key production equipment. Their main functions include providing a reaction site for industrial process gases, enabling them to complete specific chemical reactions inside the furnace, and also heating process gases in the production process to meet the temperature requirements of subsequent production processes. They are an important infrastructure to ensure the continuous and stable operation of industrial production.

[0003] From a structural perspective, mainstream industrial furnaces (including common types such as horizontal furnaces) typically employ a four-layer structure from the inside out: an air insulation layer, a furnace shell, an insulating brick layer, and a refractory brick layer. The refractory brick layer, in direct contact with the high-temperature environment inside the furnace, plays a crucial role in resisting high-temperature erosion and protecting the internal structure. The insulating brick layer primarily functions to provide thermal insulation, reducing heat loss from the furnace interior to the outside, ensuring stable internal temperature, and lowering energy consumption. The furnace shell, as the outer structure, supports the entire furnace body and protects the internal insulating and refractory brick layers. The air insulation layer further enhances the overall insulation performance of the furnace, optimizing energy efficiency.

[0004] However, during the long-term operation of horizontal furnaces, due to factors such as periodic temperature changes inside the furnace, material impact, and structural thermal expansion and contraction, gaps gradually form in the brickwork joints between the insulating brick layer and the refractory brick layer, and between the furnace shell and the insulating brick layer in most horizontal furnaces. These gaps damage the original thermal insulation structure of the furnace, allowing high-temperature flue gas and flames from inside the furnace to directly penetrate the furnace shell, leading to abnormally high furnace shell temperatures. In severe cases, the high temperature can even burn through the furnace shell, causing furnace shutdown and potentially triggering safety accidents, posing a serious threat to the company's production safety and economic benefits.

[0005] To address the aforementioned issue of high furnace shell temperatures, the industry's common approach is to shut down the furnace, cool it down, and then completely dismantle the internal insulation and refractory brick layers, followed by reconstruction to eliminate gaps and restore the furnace's normal functionality. However, this approach has significant drawbacks: it lacks specificity, resulting in substantial resource waste; maintenance costs are high, placing a heavy economic burden on enterprises; and maintenance cycles are long, failing to meet on-site production needs. This can lead to the furnace being unable to resume normal production, severely impacting the company's production schedule and continuity, and failing to meet the actual on-site production demands for rapid equipment recovery. Summary of the Invention

[0006] In view of the shortcomings of the prior art, this application provides a furnace repair system and repair method to solve the problems of low furnace repair efficiency and high cost in the prior art.

[0007] The above-mentioned objectives of this application are mainly achieved through the following technical solutions:

[0008] A furnace / kiln repair system, the repair system comprising: The main body has a first channel inside, and a receiving member is provided on the top of the main body. The receiving member has a receiving space that communicates with the first channel, so that materials can enter the first channel through the receiving member. An injection element is disposed at one end of the main body and communicates with the first channel. The injection element can be inserted into the outer wall of the furnace and extends into the gap to the target depth. A first driving member is arranged between the main body and the injection member. The first driving member can drive the material in the first channel to enter the gap inside the furnace through the injection member. The second driving member is arranged at one end of the first channel away from the injection member, and the second driving member can drive the material in the first channel to move toward the first driving member.

[0009] In an optional embodiment, the repair system further includes a guide disposed in communication between the injector and the first drive.

[0010] In an optional implementation, the guide is a flexible tubing.

[0011] In an optional implementation, the first drive element is a pump body.

[0012] In an optional embodiment, the main body is cylindrical, and the second driving component includes a drive motor and a screw rod. The screw rod is fixedly provided with screw blades, and the motor is connected to and drives the screw rod to rotate, so that the screw blades rotate and push the material to move.

[0013] In an optional embodiment, the main body is arranged horizontally and coaxially with the screw rod.

[0014] In an optional embodiment, the repair system further includes a support system on which the main body is detachably arranged, the support system supporting the main body and capable of displacing the main body.

[0015] In an optional embodiment, the load-bearing system includes a main frame and wheels, with the main components detachably mounted on the main frame.

[0016] In an optional embodiment, the repair system further includes a control unit connected to the first drive unit and the second drive unit, the control unit controlling the start and stop states of the first drive unit and the second drive unit.

[0017] Based on the same inventive concept, this application also provides a method for repairing a furnace, wherein the repair method employs the repair system described above, and the repair method includes: On the furnace, determine the location where the gap appears between the furnace shell and the insulating bricks, and open a repair hole on the furnace shell until the repair hole penetrates the furnace shell and extends into the gap; Insert the injection component into the repair hole; The materials are prepared and filled into the accommodating space; After the material enters the first channel, the second driving component is operated to drive the material to move towards the first driving component; The first driving component is operated to drive the material from the injection component into the gap inside the furnace until the material fills the gap; Remove the injection component from the furnace and wait for the material to solidify to complete the repair.

[0018] Compared with the prior art, the advantages of this application are: The repair system described in this application is used for the repair of furnaces and kilns. The repair system includes a main body, an injection component, a first driving component, and a second driving component. The main body has a first channel inside and a receiving component at its top. The receiving component has a receiving space communicating with the first channel, allowing material to enter the first channel through the receiving component. The injection component is arranged at one end of the main body and communicates with the first channel. The injection component can be inserted into the outer wall of the furnace and kiln and extends into a gap at a target depth. The first driving component is arranged between the main body and the injection component. The first driving component can drive the material in the first channel to enter the gap inside the furnace through the injection component. The second driving component is arranged at the end of the first channel away from the injection component. The second driving component can drive the material in the first channel to move towards the first driving component.

[0019] The main body has a first channel for the flow of repair materials inside. The top of the main body also has a receiving component with a accommodating space, which is connected to the first channel. The repair materials can be stored in the receiving component first, and then enter the first channel naturally or with assistance. The injection component is installed at one end of the main body and is connected to the first channel. When in use, it can be directly inserted into the outer wall of the furnace and extends to the target depth where the gap is located, providing a precise channel for the material to be injected into the gap. The first driving component is set between the main body and the injection component, and undertakes the core power role of pushing the material in the first channel towards the injection component. The second driving component is installed at the end of the first channel away from the injection component, and is used to push the material in the channel towards the first driving component, forming a coordinated power for material transportation.

[0020] First, after the repair material in the receiving component enters the first channel, the second driving component is activated, pushing the material in the channel towards the first driving component. This prevents material from accumulating at the far end of the channel and causing a conveying interruption, ensuring a continuous supply of material to the area of ​​action of the first driving component. Subsequently, the first driving component is activated, generating a directional thrust to directly press the material into the gaps at the insertion points on the outer wall of the furnace through the injection component. Since the injection component can extend to the target depth, the material can accurately fill the gaps between the insulating bricks and refractory bricks, and between the furnace shell and the insulating bricks, rather than indiscriminately covering them. Throughout the process, the injection component can flexibly adjust its insertion position according to the local high-temperature areas of the furnace shell, filling only the faulty areas with gaps without touching the intact masonry structure. This motion logic fundamentally solves the shortcomings of existing solutions: on the one hand, it eliminates the need to dismantle any intact masonry structure, injecting material only into local gaps, avoiding the waste of resources caused by dismantling; on the other hand, the material is directly filled into the gaps by being pushed by the driving component, eliminating the need to re-mold and fire insulating bricks and refractory bricks, saving the lengthy steps of dismantling the furnace, making bricks, and rebuilding.

[0021] This repair system is highly targeted, precisely locating localized gaps through the injection component and ensuring that materials reach the fault point directly through dual-drive feeding, avoiding interference with intact structures and completely solving the problem of resource waste in existing solutions. Moreover, it significantly reduces costs, eliminating the need to purchase large quantities of new insulating bricks and refractory bricks, as well as the high labor and equipment costs of complete dismantling and rebuilding. Only a small amount of repair materials are required, and the localized operation characteristics reduce maintenance costs. Furthermore, it shortens the maintenance cycle, eliminating the need to shut down the furnace for cooling or wait for brick production. Local insertion and material injection can be completed under low-load furnace operation, reducing the repair time for a single gap to within a few hours, far less than the days or even weeks of traditional solutions, thus meeting the continuous production needs of enterprises.

[0022] This repair system can precisely fill gaps to block the flow path of high-temperature flue gas and flames to the furnace shell, effectively reducing the furnace shell temperature to a safe range and avoiding the risk of furnace shell burn-through. At the same time, it ensures the overall integrity of the furnace masonry structure, taking into account both production safety and enterprise economic benefits. Attached Figure Description

[0023] To more clearly illustrate the technical solutions in the embodiments of this application, the accompanying drawings used in the description of the embodiments will be briefly introduced below. Obviously, the accompanying drawings described below are only some embodiments of this application. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0024] Figure 1 This is a schematic diagram of the structure of the repair system provided in the embodiments of this application; Figure 2 A flowchart illustrating the repair method provided in an embodiment of this application; In the diagram: 100, main component; 200, receiving component; 300, injection component; 401, first driving component; 501, drive motor; 502, screw rod; 503, screw blade; 601, main frame; 602, traveling wheel; 603, control component; 700, guide component; 801, furnace; 802, gap. Detailed Implementation

[0025] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that the description of these embodiments is for the purpose of aiding understanding the present invention, but does not constitute a limitation thereof. The specific structural and functional details disclosed herein are only for describing exemplary embodiments of the present invention. However, the present invention can be embodied in many alternative forms and should not be construed as being limited to the embodiments described herein.

[0026] To address the issue of high furnace shell temperatures, the common industry practice is to shut down the furnace and cool it down, then completely remove the internal insulation brick layers, refractory brick layers, and other masonry structures before rebuilding them to eliminate gaps and restore the furnace's normal functionality. However, this approach has significant drawbacks, as follows: The current treatment methods lack specificity and result in significant resource waste: In actual production, high furnace shell temperatures are mostly localized phenomena, meaning only specific areas of the furnace experience temperature increases due to gaps, while the masonry structure in other areas remains intact and functions properly as insulation. However, existing treatment methods fail to consider the localized nature of the problem, directly dismantling the entire masonry structure. This approach is clearly ineffective, leading to a significant waste of intact masonry and increasing unnecessary construction work and material consumption.

[0027] High maintenance costs place a heavy economic burden on enterprises: From a cost perspective, the cost of the furnace's insulation brick layer, refractory brick layer, and other masonry structures accounts for about two-thirds of the total cost of the furnace, making it a core component of the furnace's cost structure. Adopting a complete demolition and reconstruction approach means that a large amount of insulation bricks, refractory bricks, and other materials need to be purchased again, along with significant investment in labor and construction equipment costs. The overall maintenance cost is extremely high, imposing a heavy economic burden on enterprises and hindering cost control and economic efficiency improvement.

[0028] The long maintenance cycle fails to meet on-site production needs: Rebuilding the kiln requires remolding and firing the insulating and refractory bricks, a process that takes time. Combined with the dismantling of the old structure, on-site construction, and subsequent maintenance, the entire maintenance process is lengthy. In today's fast-paced industrial production and increasingly competitive market, companies have a high demand for continuous kiln operation. Prolonged maintenance prevents the kiln from being put back into production, severely impacting production schedules and continuity. This fails to meet the on-site demand for rapid equipment recovery, potentially leading to missed orders, reduced market share, and further economic losses.

[0029] like Figure 1 As shown, Figure 1 This is a schematic diagram of the structure of the repair system provided in the embodiments of this application; a repair system for a furnace 801, the repair system including a main body 100, an injection component 300, a first driving component 401 and a second driving component, wherein: like Figure 1 As shown, the main body 100 has a first channel inside, and the top of the main body 100 is provided with a receiving member 200. The receiving member 200 has a receiving space connected to the first channel, so that materials can enter the first channel through the receiving member 200. like Figure 1 As shown, the main body 100, as the core carrier and material conveying carrier of the system, can be made of high-strength alloy material to withstand the material conveying pressure and ambient temperature that may exist during the repair process. The first channel opened inside the main body 100 provides a dedicated path for material flow. The inner diameter of the channel can be configured as a gradient structure according to the viscosity of the repair material. The inner diameter of the end of the main body 100 near the injection component 300 is smaller than the inner diameter of the other end, so that the pressure concentration during material conveying is increased at one end of the main body 100, while the other end of the main body 100 can accommodate more material and reduce the risk of blockage.

[0030] like Figure 1As shown, the main body 100 has an integrally formed or detachably connected accommodating component 200 on its top. The accommodating space volume of the accommodating component 200 can be flexibly selected according to the amount of material required for a single repair, which is convenient for manual or automatic material replenishment. The inner wall of the accommodating space can be sprayed with a polytetrafluoroethylene non-stick coating to avoid the adhesion of viscous materials and the resulting residue and waste.

[0031] like Figure 1 As shown, the injection component 300 is arranged at one end of the main body 100 and is connected to the first channel. The injection component 300 can be inserted into the outer wall of the furnace 801 and extend into the gap 802 at the target depth. The injection component 300 serves as an accurate guide structure for material entering the gaps of the furnace 801. The material of the injection component 300 can be configured as hard alloy, which facilitates rapid drilling and insertion into the outer wall of the furnace 801. Multiple discharge holes are evenly opened on the side wall of the injection component 300, and the discharge holes are distributed along the circumference of the injection component 300 to ensure that the material can fill the gaps simultaneously from multiple directions under the action of driving pressure, avoiding dead corners in the gaps caused by filling in one direction. In addition, an annular sealing gasket is provided at the contact part between the injection component 300 and the outer wall of the furnace 801. After the injection component 300 is inserted, it can fit tightly against the outer wall of the furnace 801 to prevent material from leaking from the insertion gap 802, while also preventing outside air from entering the furnace and affecting the repair effect.

[0032] like Figure 1 As shown, the first driving member 401 is arranged between the main body 100 and the injection member 300. The first driving member 401 can drive the material in the first channel to enter the gap 802 inside the furnace 801 through the injection member 300.

[0033] like Figure 1 As shown, the second driving member is arranged at one end of the first channel away from the injection member 300, and the second driving member can drive the material in the first channel to move toward the first driving member 401.

[0034] In an optional embodiment, the repair system of this application is used for the repair operation of a furnace 801. The repair system includes a main body 100, an injection component 300, a first driving component 401, and a second driving component. The main body 100 has a first channel inside, and a receiving component 200 is provided on the top of the main body 100. The receiving component 200 has a receiving space communicating with the first channel, so that materials can enter the first channel through the receiving component 200. The injection component 300 is arranged at one end of the main body 100 and is connected to the first channel. The injection member 300 is connected to the outer wall of the furnace 801 and extends into the gap 802 at the target depth. The first driving member 401 is arranged between the main body 100 and the injection member 300. The first driving member 401 can drive the material in the first channel to enter the gap 802 inside the furnace 801 through the injection member 300. The second driving member is arranged at one end of the first channel away from the injection member 300. The second driving member can drive the material in the first channel to move toward the first driving member 401.

[0035] like Figure 1 As shown, the main body 100 has a first channel for the flow of repair materials inside. The top of the main body 100 also has a receiving component 200 with a accommodating space, and the accommodating space is connected to the first channel. The repair materials can be stored in the receiving component 200 first, and then enter the first channel naturally or with assistance. The injection component 300 is installed at one end of the main body 100 and is connected to the first channel. When in use, it can be directly inserted into the outer wall of the furnace 801 and extended to the target depth where the gap is located, providing a precise channel for the material to be injected into the gap. The first driving component 401 is set between the main body 100 and the injection component 300, and undertakes the core power role of pushing the material in the first channel towards the injection component 300. The second driving component is installed at the end of the first channel away from the injection component 300, and is used to push the material in the channel towards the first driving component 401, forming a coordinated power for material conveying.

[0036] First, after the repair material in the receiving component 200 enters the first channel, the second driving component is activated first, pushing the material in the channel towards the first driving component 401 to avoid material accumulation at the far end of the channel and interruption of the conveying, ensuring a continuous supply of material to the working area of ​​the first driving component 401; then the first driving component 401 is activated, generating directional thrust to press the material directly into the gap at the insertion point on the outer wall of the furnace 801 through the injection component 300. Since the injection component 300 can extend to the target depth, the material can accurately fill the gaps between the insulating bricks and refractory bricks, and between the furnace shell and the insulating bricks, rather than indiscriminately covering them; throughout the process, the injection component 300 can flexibly adjust the insertion position according to the local high temperature area of ​​the furnace shell, filling the faulty parts with gaps with material only, without touching the intact masonry structure. This motion logic fundamentally solves the shortcomings of existing solutions: on the one hand, it does not require the demolition of any intact masonry structure, but only injects materials into local gaps, avoiding the waste of resources caused by demolition; on the other hand, the materials are pushed directly to fill the gaps by the drive components, eliminating the need to re-mold and fire the insulation bricks and refractory bricks, saving the lengthy process of dismantling the furnace, making bricks, and rebuilding.

[0037] This repair system is highly targeted, using the injection unit 300 to precisely locate local gaps. Combined with dual-drive feeding, it ensures that materials reach the fault point directly, avoiding interference with intact structures and completely solving the problem of resource waste in existing solutions. Moreover, it significantly reduces costs, eliminating the need to purchase large quantities of new insulating bricks and refractory bricks, as well as the high labor and equipment costs of complete dismantling and rebuilding. Only a small amount of repair materials are required, and the localized operation characteristics reduce maintenance costs. Furthermore, it shortens the maintenance cycle, eliminating the need to shut down the furnace for cooling or wait for brick production. Local insertion and material injection can be completed under low-load operation of the 801 furnace, reducing the repair time for a single gap to within a few hours, far less than the days or even weeks of traditional solutions, thus meeting the continuous production needs of enterprises.

[0038] This repair system can precisely fill gaps to block the flow path of high-temperature flue gas and flames to the furnace shell, effectively reducing the furnace shell temperature to a safe range and avoiding the risk of furnace shell burn-through. At the same time, it ensures the overall integrity of the 801 masonry structure of the furnace, taking into account both production safety and enterprise economic benefits.

[0039] like Figure 1 As shown, in an optional embodiment, the repair system further includes a guide 700, which is disposed in communication between the injector 300 and the first drive 401.

[0040] The guide component 700 is a transitional structure with dual functions of pressure buffering and material guidance. The guide component 700 ensures no material leakage and reduces material flow resistance through its smooth inner wall. Simultaneously, it uniformly guides the high-pressure material output from the first drive component 401 to the injection component 300, avoiding localized turbulence caused by excessive material flow velocity and preventing viscous materials from accumulating and clogging at corners. The addition of the guide component 700, through its structural optimization, solves the problems of "pressure loss" and "turbulent flow" in material conveying. Especially when repairing the arc-shaped outer wall gaps of the furnace 801, it effectively buffers the instantaneous high pressure of the first drive component 401, preventing damage to the injection component 300 due to pressure impact, while ensuring stable material entry into the injection component 300 and improving filling accuracy.

[0041] like Figure 1 As shown, in an optional embodiment, the guide 700 is a flexible tube. This flexible tube ensures both the flexibility and bendability of the guide 700 and the ability to withstand material conveying pressure, preventing the tube from breaking or deforming excessively under high pressure. In practical applications, when the repair position of the furnace 801 is located at a corner or needs to cross a protruding structure of the furnace body, the flexible guide 700 can be flexibly bent according to the insertion angle of the injection component 300, without adjusting the fixed position of the first driving component 401 and the main body 100, thus solving the problem that the rigid connection guide 700 cannot adapt to complex furnace surfaces. At the same time, both ends of the flexible tube are equipped with quick-connect couplings, which can quickly complete the disassembly and installation with the injection component 300 and the first driving component 401, facilitating the rapid replacement of guides 700 of different lengths on site to adapt to different repair distance requirements.

[0042] Compared to rigid pipes of fixed length in existing technologies, the flexible guide 700 significantly improves the operational flexibility of the system, especially in the confined space around the furnace 801, reducing the number of equipment movements and shortening the preparation time for each repair.

[0043] like Figure 1 As shown, in an optional embodiment, the first driving component 401 is a pump body. The pump body can be a plunger pump or an internal gear pump. When the repair material is a high-viscosity refractory paste, a plunger pump is selected. The reciprocating motion of the plunger generates pulsed high pressure, which can force the viscous material into narrow gaps. When the material is a low-viscosity ceramic fiber slurry, an internal gear pump is selected. It continuously transports the material through a closed chamber formed by gear meshing, with low flow stability error, avoiding uneven filling caused by flow rate fluctuations.

[0044] Furthermore, the pump body integrates flow and pressure sensors. When the material flow rate is detected to be lower than the preset value, it automatically increases the pump output pressure until the flow rate returns to normal, preventing material conveying interruptions caused by gap blockage. Simultaneously, a filter element is installed at the pump inlet to filter out minute impurities in the material, preventing them from entering the pump body and causing wear. This not only solves the material compatibility problem but also improves conveying stability through intelligent adjustment, providing a universal drive solution for repairing gaps in furnaces and kilns of different materials and widths.

[0045] like Figure 1 As shown, in an optional embodiment, the main body 100 is cylindrical, and the second driving component includes a driving motor 501 and a spiral rod 502. A spiral blade 503 is fixedly provided on the spiral rod 502. The motor is connected to and drives the spiral rod 502 to rotate, so that the spiral blade 503 rotates and pushes the material to move.

[0046] The cylindrical main body 100 is made of seamless steel pipe. The inner wall of the main body 100 is coated with a nano-ceramic anti-stick coating, which can reduce the friction coefficient between the material and the inner wall and avoid the increase in conveying resistance caused by the adhesion of viscous materials. The length of the screw rod 502 is adapted to the length of the first channel of the main body 100. The screw blades 503 can be made of stainless steel and are fixed to the screw rod 502 by welding. The pitch of the blades can be configured as a gradual structure, with the pitch near the first drive member 401 being smaller than the pitch at the other end, so that the area near the feed end of the receiving member 200 can quickly accommodate and initially push the material. The other end area can increase the degree of material compression by reducing the pitch, so that the material forms a certain pre-pressure before reaching the first drive member 401, reducing the pressurization load on the first drive member 401. The drive motor 501 is a servo motor, which is rigidly connected to the screw rod 502 through a coupling. A torque sensor can be installed on the motor output shaft. When the torque of the screw rod 502 exceeds the preset value due to material blockage, the motor automatically reverses and then pushes forward, which can effectively relieve minor blockages and avoid motor overload damage.

[0047] like Figure 1 As shown, in an optional embodiment, the main body 100 is arranged horizontally, and the main body 100 and the screw rod 502 are arranged coaxially.

[0048] Based on material gravity balance and conveying efficiency, the horizontal arrangement of the main component 100 avoids material deposition at the bottom of the first channel due to tilting. If the main component 100 tilts upward, material tends to accumulate at the lower end of the channel, causing the spiral blades 503 to idle. If tilted downward, material tends to flow too quickly towards the first drive component 401 due to gravity, causing localized material overload. The coaxial arrangement ensures that the central axis of the spiral rod 502 coincides with the central axis of the first channel, making the gap 802 between the spiral blades 503 and the inner wall of the channel uniform. This avoids material leakage or insufficient local pushing force due to uneven gap 802. When the spiral rod 502 rotates at high speed, the uniform gap 802 ensures that the thrust of the blades on the material is consistently distributed along the circumference, allowing the material to move smoothly along the channel axis without radial deviation. Especially when conveying ceramic fiber fillers with high particle content, this prevents particles from getting stuck between the blades and the inner wall, causing wear and improving the stability of material conveying. It also reduces the frequency of equipment maintenance and extends the service life of the spiral rod 502 and the blades.

[0049] like Figure 1 As shown, in an optional embodiment, the repair system further includes a support system, on which the main body 100 is detachably arranged. The support system supports the main body 100 and can move the main body 100.

[0050] When there is a need for continuous repair at multiple locations on site, the load-bearing system ensures both load-bearing capacity and ease of movement for operators. In practical applications, when there are multiple local gaps on the same side of the furnace 801, operators do not need to repeatedly move the repair system. They only need to push the load-bearing system to move the main body 100 to different repair locations. During the movement, the main body 100 remains horizontal, preventing material spillage in the channel or misalignment of the drive components. This can shorten the total repair time at multiple locations and improve the on-site applicability of the system.

[0051] like Figure 1 As shown, in an optional embodiment, the load-bearing system includes a main frame 601 and wheels 602, with the main body 100 detachably mounted on the main frame 601. It possesses excellent wear resistance and can move smoothly on concrete or steel plate surfaces surrounding the furnace 801, avoiding swaying of the load-bearing system due to uneven ground. This significantly improves the mobility and safety of the equipment, providing a reliable mobile foundation for continuous on-site repairs.

[0052] In an optional embodiment, the repair system further includes a control unit 603 that connects the first drive unit 401 and the second drive unit, the control unit 603 controlling the start and stop states of the first drive unit 401 and the second drive unit.

[0053] Upon startup, the controller 603 first triggers the second drive unit to operate. After a stable material flow is established in the first channel, the first drive unit 401 is then activated to prevent a sudden pressure surge caused by the first drive unit 401 operating without load. Upon shutdown, the first drive unit 401 is first shut off. Once the remaining material in the first channel has been largely conveyed, the second drive unit is then shut off to prevent material residue and solidification within the channel. This not only reduces the difficulty of manual operation but also improves the safety and stability of the system operation.

[0054] like Figure 1 , Figure 2 As shown, Figure 2 A flowchart illustrating the repair method provided in this application embodiment; based on the same inventive concept, this application also provides a repair method for a furnace 801, wherein the repair method employs the repair system described above, and the repair method includes: On the furnace 801, determine the location of the gap 802 between the furnace shell and the insulating brick, and open a repair hole on the furnace shell until the repair hole penetrates the furnace shell and extends into the gap 802. Insert the injection component 300 into the repair hole; The materials are prepared and filled into the accommodating space; After the material enters the first channel, the second driving component is operated to drive the material to move towards the first driving component 401; The first driving component 401 is operated to drive the material from the injection component 300 into the gap 802 inside the furnace 801 until the material fills the gap 802. Remove the injection component 300 from the furnace 801 and complete the repair after the material has solidified.

[0055] It should be understood that the terms "first," "second," etc., are used only for distinguishing descriptions and should not be construed as indicating or implying relative importance.
