[0024] As Figures 1 - 5 shown, it shows an integrated prefabricated cabin based on a non-metallic high-strength fiber fireproof board in an embodiment of this disclosure. Aiming at the problem of poor waterproof effect at the splicing joints of the traditional prefabricated cabin wall panels, especially at the corner joints, this prefabricated cabin improves the waterproof performance by optimizing the wall structure of the cabin body. Adopting a multi-layer structure of non-metallic fiber fireproof board, polymeric polystyrene board and rock wool sandwich panel not only meets various functional requirements such as fire prevention and heat preservation, but also focuses on the waterproof design at the corners. Using water-blocking vertical boards to enclose an accommodation space, and cooperating with water-blocking columns to block the corner joints of the non-metallic fiber fireproof board, effectively preventing external moisture from penetrating; the support columns enhance the structural stability while assisting the water-blocking columns to better play the waterproof role, ensuring that the internal equipment and systems of the prefabricated cabin are not affected by water seepage.

[0025] The non-metallic fiber fireproof board 104 is used as the outer layer of the cabin wall, and a non-metallic fiber fireproof board with high strength, high temperature resistance and good waterproof performance is selected. This kind of board is made of inorganic fiber and high-performance resin through a hot pressing process, and its surface is waterproofed, which can effectively resist the erosion of external rainwater and moisture. At the same time, it has good fireproof performance, providing the first line of safety defense for the prefabricated cabin, ensuring that while maintaining the strength, it does not affect the lightness of the overall structure.

[0026] The expanded polystyrene board 105 in the middle layer mainly plays the role of heat insulation. It is made by adding special flame retardants and additives to polystyrene particles and then heating, foaming and curing. The expanded polystyrene board has a low thermal conductivity, which can effectively prevent heat transfer and keep the temperature inside the prefabricated cabin stable. Its thickness is adjusted according to the climatic conditions of the environment where the prefabricated cabin is located.

[0027] The rock wool sandwich panel 106 as the inner layer has multiple functions such as fireproofing, sound insulation and heat insulation. It uses rock wool as the core material, and thin steel plates are laminated on both sides and bonded by high-strength adhesives. The rock wool sandwich panel can not only further enhance the fireproof performance of the prefabricated cabin, but also effectively absorb the noise generated by the operation of internal equipment, providing a quiet working environment for operators.

[0028] At the inner corner of the non-metallic fiber fireproof board 104, two water-blocking vertical plates 107 are fixed by welding or high-strength adhesives. The water-blocking vertical plates 107 are made of stainless steel or aluminum alloy, with good corrosion resistance and waterproof performance. The two water-blocking vertical plates 107 are arranged perpendicular to each other, forming a receiving space 108 therebetween. The height of the water-blocking vertical plates 107 is the same as that of the non-metallic fiber fireproof board 104, ensuring that the corner area can be completely covered to prevent moisture from seeping in from the side.

[0029] The water-blocking column 109 is shaped to fit the receiving space 108 and is exactly located within the receiving space 108. One side of the water-blocking column 109 is closely attached to the corner connection of the non-metallic fiber fireproof board 104, completely blocking the possible water-seeping gaps and effectively preventing moisture from entering the interior of the cabin. The height of the water-blocking column 109 is the same as the height of the cabin, ensuring the waterproof effect of the entire corner area.

[0030] The support column 110 is located on the side of the water-blocking column 109 away from the non-metallic fiber fireproof board 104. The support column 110 is firmly connected to the bottom frame and top frame of the cabin by bolts or welding, providing strong structural support for the cabin. At the same time, the support column 110 cooperates with the water-blocking column 109 to enhance the stability of the water-blocking column 109, enabling it to withstand greater pressure when blocking moisture penetration.

[0031] The design of water retaining vertical plates and water retaining columns effectively prevents water from penetrating from the corner joints of the non-metallic fiber fireproof panels, greatly improving the waterproof performance of the prefabricated cabin. After actual testing, there was no water seepage inside the prefabricated cabin in severe rainstorm environments, ensuring the normal operation and service life of the internal equipment.

[0032] The multi-layer wall structure not only has excellent waterproof performance, but also takes into account multiple functions such as fire prevention, heat preservation, and sound insulation. The non-metallic fiber fireproof board provides fire protection, and the polymer polystyrene board and rock wool sandwich panel achieve thermal insulation and sound insulation respectively, meeting the diverse needs of prefabricated cabins in different application scenarios.

[0033] The provision of the support columns 110 significantly enhances the structural strength of the corners of the prefabricated cabin, making the cabin more stable when subjected to external pressure and vibration, thereby improving the overall reliability and safety of the prefabricated cabin and extending the service life of the prefabricated cabin.

[0034] In some examples, such as Figures 1 - 5 As shown, the support columns 110 and the water retaining columns 109 are designed to form a square, which can further optimize the structural stability and waterproof performance of the corners of the prefabricated cabin. The square structure has good symmetry and mechanical stability, which can better disperse external forces and enhance the overall firmness of the prefabricated cabin. Clarifying the vertical and coplanar relationship of each side is helpful for precise manufacturing and installation, ensuring that the water retaining columns 109 can more tightly block the corner connection of the non-metallic fiber fireproof board 104 and improve the waterproof effect. At the same time, the regular square structure is easy to connect with other parts of the cabin, improving the coordination and reliability of the overall structure.

[0035] The support column 110 is composed of four sides, namely the first side 111, the second side 112, the third side 113 and the fourth side 114, which are connected in sequence to form a square frame. The first side 111 and the third side 113 are parallel to each other, and the second side 112 is perpendicular to the third side 113, forming a right-angle structure. This right-angle structure can effectively withstand forces from different directions and enhance the support capacity at the corners. For example, when the prefabricated cabin is subjected to horizontal forces generated by side wind or ground vibration, the vertical second side 112 and the third side 113 can better resist and disperse these forces to prevent deformation of the cabin structure.

[0036] The water retaining column 109 also forms a square structure by sequentially connecting the fifth side 115, the sixth side 116, the seventh side 117 and the eighth side 118. The sixth side 116 is perpendicular to the seventh side 117, forming a right-angle structure matching the supporting column 109, further strengthening the structural stability at the corner.

[0037] The fifth side 115 is coplanar with the second side 112 of the support column 110, and the eighth side 118 is coplanar with the third side 113 of the support column 110. This coplanar relationship enables the two columns to form a tight fit at the corner. The water-blocking column 109 can rely on the structural strength of the support column 110 to more effectively block water penetration. For example, when rain impacts the corner connection of the non-metallic fiber fireproof board 104, the water-blocking column 109 transfers the water pressure to the support column 110 through the coplanar sides, and the two work together to prevent water from entering the interior of the cabin.

[0038] During the assembly process of the prefabricated cabin, first, the support column 110 is fixed at the corner of the cabin according to the designed position and firmly connected to the chassis and the top frame of the cabin by bolts or welding. Then, the water-blocking column 109 is installed in the accommodating space 108, ensuring that the fifth side 115 is coplanar with the second side 112 and the eighth side 118 is coplanar with the third side 113. At the coplanar contact parts, sealant can be used for sealing treatment to further enhance the waterproof performance and prevent water from seeping in through the gaps between the columns.

[0039] The square structure formed by the support column 110 and the water-blocking column 109, as well as the design of perpendicularity and coplanarity between the sides, significantly improves the structural strength and stability at the corner of the prefabricated cabin. It effectively guarantees the integrity of the overall structure of the cabin and extends the service life of the prefabricated cabin. The coplanar design enables the water-blocking column 109 to fit more closely to the corner connection of the non-metallic fiber fireproof board 104, reducing possible water seepage gaps. After the waterproof performance test, under the simulated environment of continuous heavy rainfall, the water seepage phenomenon inside the prefabricated cabin has been significantly improved, the seepage probability has been reduced, and the safety and stability of the operating environment of the equipment inside the prefabricated cabin have been improved.

[0040] In some examples, as Figures 1 - 5 shown, a double-layer cabin bottom is added and a support skeleton is arranged inside the cabin wall to further improve the performance of the prefabricated cabin in terms of bottom waterproofing and overall structural stability. High-strength and corrosion-resistant metal materials, such as stainless steel plates, are used, and the thickness is determined according to the size and load-bearing requirements of the prefabricated cabin, generally between 8 - 12 mm. The water-blocking vertical edge 121 encloses a ring and is an integral structure with the upper cabin bottom 119, forming a closed sealed space. The height of the water-blocking vertical edge 121 can be between 50 - 200 mm, and its inner side closely adheres to the lower part of the inner wall of the rock wool sandwich panel 106, forming an effective waterproof barrier. When installing the prefabricated cabin, ensure the sealing between the water-blocking vertical edge and the rock wool sandwich panel, and waterproof sealant can be used to fill the gaps to prevent water from seeping between the two.

[0041] The lower bilge 120 and the upper bilge 119 are connected by support structures at certain intervals. These support structures can be section steel or special metal struts, and the interval distance is set according to the size of the cabin and the load-bearing requirements. The double-bottom structure not only enhances the waterproof performance of the bilge, but also improves the adaptability of the cabin to ground unevenness and the overall load-bearing capacity.

[0042] The support skeleton 122 is a square tube frame structure with vertical parts and inclined support parts. Multiple cavities 123 are divided inside the frame. The support skeleton 122 is installed in the expanded polystyrene board 105. During the assembly process of the prefabricated cabin wall, first place the support skeleton in the predetermined position, and then expand the expanded polystyrene board inside it, so that the expanded polystyrene board fills the cavities 123 of the support skeleton.

[0043] The support skeleton 122 enhances the structural strength of the cabin wall. When the prefabricated cabin is subjected to external impacts, wind forces and other acting forces, the support skeleton can disperse these forces and prevent local overloading and damage of the cabin wall. At the same time, the expanded polystyrene board filled in the cavities 123 ensures that the heat preservation performance is not affected.

[0044] The double-bottom combined with the water-blocking vertical edge of the upper bilge significantly improves the waterproof ability of the bottom of the prefabricated cabin and reduces the risk of damage to the equipment inside the cabin due to water immersion. The setting of the support skeleton improves the structural strength of the cabin wall. In actual use, it can better resist the influence of external environmental factors on the cabin. At the same time, the cavities inside the support skeleton provide convenience for the layout of internal facilities, optimize the utilization of the internal space of the prefabricated cabin, make the installation, wiring and pipeline laying of equipment more orderly, and improve the overall functionality and maintainability of the prefabricated cabin.

[0045] In some examples, as Figures 6 - 13 shown, an installation opening 101 is provided on one side of the cabin 100 for subsequent installation of the channel member 200. At the same time, the cabin is equipped with a cabin door 102 to facilitate personnel entry and exit and equipment maintenance. On the cabin door 102, exhaust vents 103 are reasonably set to ensure the discharge of internal air.

[0046] The channel member 200 is installed at the installation opening 101 and is tightly fixed to the cabin 100 by a reliable connection method. A through ventilation duct 201 is provided inside the channel member 200, and air inlets 202 and air outlets 203 are formed at both ends of the ventilation duct 201. An appropriate fan is installed in the ventilation duct 201 to generate sufficient wind force to realize the circulation of air inside and outside the prefabricated cabin and meet the ventilation requirements such as heat dissipation inside the cabin.

[0047] The grid member 300 is arranged at the air inlet 202 and is firmly connected to the channel member 200. A large number of grid openings 301 are distributed on the grid member 300. These grid openings are arranged in a certain pattern, which can not only allow air to pass through smoothly, but also play a preliminary filtering role for impurities such as dust with larger particles.

[0048] At each grid opening 301, a swing baffle 400 is swingably arranged through a connecting structure. The swing baffle 400 is made of a light material to ensure that it can swing easily under the action of the air flow generated by the fan. When the fan is not turned on, the swing baffle 400 naturally hangs down under the influence of its own gravity, closing the grid opening 301 and blocking the entry of external dust. When the fan is started, the generated air flow surges in from the air inlet 202, driving the swing baffle 400 to swing upward, thus opening the grid opening 301 and enabling the air to flow smoothly into the ventilation duct 201.

[0049] The principle of this design is to use the air flow generated during the operation of the fan to drive the swing baffle 400 to open, realizing the ventilation function. When the fan stops working, the swing baffle 400 automatically closes by relying on its own gravity to prevent dust from entering. Compared with the traditional prefabricated cabin that simply relies on the fan for ventilation, this design effectively ensures the ventilation and heat dissipation of the prefabricated cabin while greatly improving the cleanliness of the cabin environment, thereby extending the service life of the equipment in the cabin and reducing the overall maintenance cost.

[0050] If the prefabricated cabin is in an environment with a lot of dust, such as areas near mines or construction sites, an additional layer of coarse filter can be installed outside the grid member 300 to further enhance the dust filtering effect. The coarse filter can be made of a material that is easy to replace and is replaced regularly to ensure the normal operation of the ventilation system.

[0051] In a humid environment, to avoid water vapor entering the prefabricated cabin and damaging the internal equipment, a dehumidification device can be installed in the ventilation duct 201 to dehumidify the incoming air. At the same time, the sealing performance of the cabin body 100 is strengthened. For example, a sealing material is installed at the joint between the cabin door 102 and the cabin body 100 to prevent water vapor from penetrating into the cabin through the gaps.

[0052] Through the ventilation design of this prefabricated cabin, while ensuring the heat dissipation and ventilation required for the normal operation of the monitoring equipment, it effectively blocks the entry of dust, ensuring the stable operation of the monitoring equipment and providing a reliable guarantee for the monitoring work in the production workshop.

[0053] In some examples, as Figures 6 - 13 shown, setting the air inlet 202 downward has many advantages, such as effectively reducing the possibility of rainwater, sundries, etc. directly entering the ventilation duct 201. In the actual design, the part of the channel member 200 close to the air inlet 202 has been specially optimized in structure. The edge of the air inlet 202 adopts a design of inward folding to form a structure similar to a lip. This structure can not only enhance the strength of the air inlet 202 but also block larger particle sundries from sliding into the ventilation duct 201 along the edge of the air inlet to a certain extent.

[0054] In addition, an inclined rain cover is installed just above the air inlet 202. The rain cover is made of high-strength, weather-resistant materials, such as stainless steel or engineering plastics, and its inclination angle can effectively prevent rain from falling directly into the air inlet 202, while not causing significant obstruction to the normal inflow of air. The rain cover is firmly connected to the channel member 200 by screws or welding, ensuring stable operation under various adverse weather conditions.

[0055] The air outlets 203 are arranged horizontally toward the interior of the cabin and are arranged in a matrix. This design helps to more evenly deliver the processed air to various areas inside the cabin body 100, thereby improving the ventilation and heat dissipation effect.

[0056] The air outlets 203 are arranged in a matrix. For example, in a larger prefabricated cabin, the air outlets 203 may be arranged in a matrix on the side surface of the channel member 200 facing the cabin. Each air outlet 203 has the same size and is square or circular in shape. The specific size is designed according to the size of the prefabricated cabin and the ventilation requirements. A certain distance is maintained between adjacent air outlets 203 to avoid mutual interference of the blown airflows, ensure that the air can enter the cabin body 100 evenly and stably, meet the requirements of the cabin equipment for heat dissipation and ventilation, and maintain a suitable temperature environment in the cabin.

[0057] In some examples, the mesh member 300 is composed of a first mesh plate 310 and a second mesh plate 320 arranged in sequence from top to bottom. The first mesh plate 310 and the second mesh plate 320 are both made of corrosion-resistant metal materials, such as stainless steel, and are made into a mesh structure through a stamping process. The mesh size of the first mesh plate 310 is slightly larger than that of the second mesh plate 320. This design enables the first mesh plate 310 to initially block larger particles of dust and impurities, while the second mesh plate 320 further filters smaller particles of pollutants.

[0058] A transversely arranged spacing space 302 is formed between the first mesh plate 310 and the second mesh plate 320. In the actual production process of the prefabricated cabin, the distance between the first mesh plate 310 and the second mesh plate 320 is maintained by welding or riveting spacing columns at the edges of the first mesh plate 310 and the second mesh plate 320 to ensure the stability of the spacing space 302. The spacing columns are made of the same corrosion-resistant material as the mesh plates and are evenly distributed at the edges of the mesh plates to ensure that the spacing between each part of the spacing space 302 is consistent.

[0059] The filter element 500 is made of high-efficiency air filter material, such as activated carbon fiber filter or glass fiber filter paper, and is in the shape of a rectangular sheet, the width of which matches the height of the spacing space 302 , and the length is customized according to the width of the mesh element 300 .

[0060] When installing the filter element 500, first insert one end of the filter element 500 into one side of the spacer 302, and then pull the filter element 500 horizontally along the spacer 302 so that it completely passes through the spacer 302 and extends a certain length from the other side for subsequent replacement operations. To ensure the stability of the filter element 500 within the spacer 302, at both ends where the filter element 500 extends out of the spacer 302, it is fixed to the edge of the grid member 300 using detachable buckles or clips. In this way, when the filter element 500 has adsorbed dust to a certain extent and needs to be replaced, simply loosen the buckle or clip, and then the old filter element 500 can be conveniently withdrawn and a new filter element 500 can be inserted.

[0061] The principle of this structural design is to use the different mesh sizes of the first mesh plate 310 and the second mesh plate 320 for two-stage filtration, and at the same time, install the filter element 500 by means of the intermediate spacer 302 to further enhance the filtration effect. When air enters the ventilation duct 201, it first passes through the first mesh plate 310 to filter out larger particle impurities, then passes through the filter element 500 to adsorb fine particles and harmful gases, and finally passes through the second mesh plate 320 for secondary filtration to ensure that the air entering the prefabricated cabin is relatively clean.

[0062] Compared with the traditional single-filter screen filtration method, this design greatly improves the accuracy and efficiency of air filtration, can effectively block dust in the production workshop from entering the prefabricated cabin, and ensures the stable operation of monitoring equipment. At the same time, the detachable and replaceable design of the filter element 500 facilitates daily maintenance and reduces the use cost.

[0063] If the prefabricated cabin is in an environment with a relatively high degree of pollution, such as near a chemical production workshop, a filter element 500 with a higher filtration grade can be selected, such as a composite filter screen with special adsorbents added, to enhance the filtering ability for harmful gases and fine particles. At the same time, appropriately reduce the mesh size of the first mesh plate 310 and the second mesh plate 320 to further improve the overall filtration effect.

[0064] When working in a high-temperature environment, considering the high-temperature resistance performance of the filter element 500, a filter material with good high-temperature resistance characteristics can be selected, such as a ceramic fiber filter screen. And regularly check the fixing components such as the spacer posts and buckles to prevent deformation of the material due to high temperature, which may affect the stability of the grid member 300 and the filter element 500.

[0065] In some examples, such as Figures 6 - 13As shown in the figure, on both sides of the channel member 200, a feeding roller 600 and a winding roller 700 are installed. The filter member 500 is made of a flexible non-woven filter material, which has good air permeability and filtration performance, and is soft in texture, facilitating winding around the feeding roller 600 and the winding roller 700. One end of the filter member 500 is firmly connected to the feeding roller 600 and wound neatly around the feeding roller 600 for multiple turns. During the winding process, by controlling the winding tension, it is ensured that the filter member 500 is tightly arranged on the feeding roller 600 to avoid wrinkles or looseness. The other end of the filter member 500 is connected to the winding roller 700 in a similar manner. When the feeding roller 600 rotates to release the filter member 500, the winding roller 700 rotates synchronously to roll up the used filter member 500, realizing the continuous replacement of the filter member 500.

[0066] To achieve the coordinated operation of the feeding roller 600 and the winding roller 700, an automated control device is provided. The control device includes a motor, a reducer, and a sensor. The motor provides power for the feeding roller 600 and the winding roller 700, and the reducer is used to adjust the rotational speed output by the motor to match the appropriate operating speed of the filter member 500. The sensor monitors the usage condition of the filter member 500 in real time. For example, it judges the degree of blockage by detecting the change in the resistance of the filter member 500. When the sensor detects that the resistance of the filter member 500 reaches the set threshold value, the control device automatically starts the motor to rotate the feeding roller 600 and the winding roller 700, sending a new filter member 500 into the working area and rolling up the used part at the same time.

[0067] In an environment with a relatively high dust concentration, such as in a prefabricated cabin near a cement factory or a mine, to ensure the filtration effect and increase the replacement frequency of the filter member 500. By adjusting the parameters in the control device, the sensor becomes more sensitive to the change in the resistance of the filter member 500. Once the resistance slightly rises, the feeding roller 600 and the winding roller 700 are promptly started to replace the filter member 500. At the same time, a non-woven material with a higher filtration accuracy is selected as the filter member 500 to better intercept dust particles.

[0068] If the space in the prefabricated cabin is limited, to make rational use of the space, the feeding roller 600 and the winding roller 700 are designed into a compact structure. For example, a flat roller body is adopted, and the mounting bracket is designed to be thinner and lighter, minimizing the occupation of the surrounding space of the channel member 200 as much as possible. In addition, the layout of the control device is optimized and integrated into a smaller module, which is installed on the side or back of the channel member 200 at a position that does not affect ventilation and filtration operations.

[0069] In some examples, such as Figures 6 - 13As shown, the outer cover 800 is generally in the shape of a cuboid and can closely cover the outside of the channel member 200, forming a receiving space 801 between it and the channel member 200. When installing the outer cover 800, the outer cover 800 is firmly fixed to the cabin body 100 through a preset card slot or bolt hole outside the cabin body 100. A sealing strip is provided between the outer cover 800 and the channel member 200 to prevent external dust, rainwater, etc. from entering the receiving space 801 and affecting the normal operation of the feeding roller 600, the winding roller 700, and the filter element 500.

[0070] Inside the receiving space 801, several folding filter rollers 900 are reasonably distributed according to the running track of the filter element 500. Between the interval space 302 and the winding roller 700 and between the interval space 302 and the feeding roller 600, 3 - 5 folding filter rollers 900 are respectively arranged, and the specific quantity can be adjusted according to the size of the receiving space 801 and the length of the filter element 500.

[0071] High - precision bearings are installed at both ends of the folding filter roller 900, and the bearings are embedded in the bearing seats preset on the inner wall of the outer cover 800, enabling the folding filter roller 900 to rotate flexibly. The surface of the folding filter roller 900 is specially treated with a smooth and wear - resistant coating to reduce the friction when the filter element 500 bypasses the folding filter roller 900 and avoid damaging the filter element 500 at the same time.

[0072] The flexible filter element 500 starts from the feeding roller 600, bypasses the folding filter roller 900 located between the interval space 302 and the feeding roller 600 in sequence, then passes through the interval space 302 for air filtration, and then bypasses the folding filter roller 900 located between the interval space 302 and the winding roller 700, and finally winds onto the winding roller 700.

[0073] When designing the position and angle of the folding filter roller 900, ensure that the wrap angle of the filter element 500 bypassing the folding filter roller 900 is greater than or equal to 180°. In this way, when the filter element 500 moves as the feeding roller 600 and the winding roller 700 rotate, due to the blocking and guiding effects of the folding filter roller 900, the filter element 500 will bend at a large angle. During this process, the dust attached to the filter element 500 is affected by centrifugal force and its own gravity, and is more likely to fall off from the filter element 500 and drop into the dust collection groove preset at the bottom of the receiving space 801.

[0074] The setting of the outer cover 800 not only provides protection for the feeding roller 600, the winding roller 700, and the filter element 500 to prevent them from being interfered by external environmental factors, but also provides space for the installation of the folding filter roller 900. The folding filter roller 900 enables the filter element 500 to bend at a large angle and uses physical principles to achieve the automatic shedding of dust. This design effectively extends the service life of the filter element 500, reduces the frequency of manual cleaning or replacement of the filter element 500, and improves the operation efficiency and stability of the prefabricated cabin ventilation and filtration system.

[0075] In some examples, such as Figures 6 - 13 shown, the first soot blowing pipe 1100 is made of stainless steel, which has good corrosion resistance and high temperature resistance and can adapt to the complex environment in the prefabricated cabin. Its pipe diameter is reasonably designed according to the size of the air outlet 203 and the required soot blowing wind force. One end of the first soot blowing pipe 1100 is tightly connected to the air outlet 203 through a flange to ensure the tightness of the connection and prevent gas leakage from affecting the soot blowing effect. The other end is connected to the first soot blowing head 1101. The first soot blowing head 1101 is flat, and multiple small air jet holes can be arranged inside. These air jet holes are distributed in a fan shape to blow the gas more evenly onto the filter element 500.

[0076] Inside the outer cover 800 of the prefabricated cabin, along one side of the channel member 200, the first soot blowing pipe 1100 is fixed in place by a special pipe clamp, ensuring that the first soot blowing head 1101 is accurately located between the folding filter roller 900 and the winding roller 700 and is facing the filter element 500. To prevent the soot blowing pipe from loosening due to vibration during operation, a rubber pad is also provided between the pipe clamp and the soot blowing pipe to play a role in shock absorption and fastening.

[0077] The material of the second soot blowing pipe 1200 is the same as that of the first soot blowing pipe 1100, also stainless steel. Its pipe diameter and connection method are similar to those of the first soot blowing pipe 1100. One end is connected to the air outlet 203 through a flange, and the other end is connected to the second soot blowing head 1201. The second soot blowing head 1201 is also flat, but the distribution angle of the air jet holes is adjusted according to its positional relationship with the feeding roller 600 and the folding filter roller 900 to better cover the surface of the filter element 500.

[0078] The second soot blowing pipe 1200 is fixed inside the outer cover 800 along the other side of the channel member 200 by a pipe clamp, so that the second soot blowing head 1201 is located between the folding filter roller 900 and the feeding roller 600 and is accurately facing the filter element 500. During the installation process, the firmness of the pipe clamp and the shock absorption effect of the rubber pad between the pipe clamp and the soot blowing pipe should also be ensured.

[0079] Part of the air discharged from the air outlet 203 is respectively conveyed to the first soot blowing head 1101 and the second soot blowing head 1201 through the first soot blowing pipe 1100 and the second soot blowing pipe 1200. When the filter element 500 moves driven by the feeding roller 600 and the winding roller 700, the airflows ejected from the first soot blowing head 1101 and the second soot blowing head 1201 directly act on the surface of the filter element 500 to blow off the dust attached to the filter element 500. Since the folding filter roller 900 has made the dust on the filter element 500 in a relatively loose state, combined with the airflows blown out by the soot blowing pipes, the dust on the filter element 500 can be more effectively removed.

[0080] The arrangement of the first soot blower pipe 1100 and the second soot blower pipe 1200 further enhances the cleaning effect on the filter element 500, greatly extends the service life of the filter element 500, reduces the frequency of replacing the filter element 500, and thus reduces the operating cost of the prefabricated cabin ventilation system. At the same time, the air at the air outlet 203 is used for soot blowing without additional power equipment, improving the energy utilization efficiency.

[0081] In some examples, such as Figures 6 - 13 shown, an inclined dust baffle 1300 is designed, and the shape of the inclined dust baffle 1300 is customized according to the internal space of the first soot blowing head 1101 and the second soot blowing head 1201. It is trapezoidal as a whole, with a shorter upper base and a longer lower base to adapt to the airflow channel structure that becomes wider from narrow inside the soot blowing head. The inclination angle of the inclined dust baffle 1300 is adjusted to effectively block the dust from directly blowing back into the soot blower pipe in the reverse direction, and at the same time enable the blown-off dust to slide smoothly along the inclined surface.

[0082] Inside the first soot blowing head 1101 and the second soot blowing head 1201, on the two side walls along the airflow direction, card slots matching the edges of the inclined dust baffle 1300 are respectively arranged. The two side edges of the inclined dust baffle 1300 are inserted into the card slots to ensure that the inclined dust baffle 1300 will not loosen or displace under the impact of high-speed airflow. At the same time, for the convenience of later maintenance and replacement, the connection between the card slot and the inclined dust baffle 1300 is designed to be detachable, and the inclined dust baffle 1300 can be taken out of the card slot with a simple tool.

[0083] When the first soot blowing head 1101 and the second soot blowing head 1201 blow out airflow towards the filter element 500 to remove dust, some of the blown-up dust may tend to enter the soot blower pipe in the reverse direction under the complex action of the airflow. At this time, the inclined dust baffle 1300 plays a blocking role, changing the movement trajectory of the dust and making the dust slide along the inclined surface to avoid the dust entering the inside of the soot blower pipe, thereby preventing the dust from blocking or wearing the soot blower pipe and ensuring the normal operation of the soot blowing system.

[0084] The setting of the inclined dust baffle 1300 significantly improves the reliability and stability of the soot blowing system. It effectively solves the problem of dust entering the soot blower pipe in the reverse direction, extends the service life of the soot blower pipe and related components, reduces the maintenance cost and downtime caused by the blockage or damage of the soot blower pipe, and further improves the overall operating efficiency of the prefabricated cabin ventilation and filtration system.

[0085] In a working environment with a lot of sand and dust, such as the prefabricated cabin in desert areas, the sand and dust are large and the particles are relatively coarse. For such working conditions, the thickness of the inclined dust baffle 1300 can be appropriately increased to enhance its impact resistance and prevent the sand and dust particles from damaging the inclined dust baffle 1300.

[0086] In a high-humidity working environment, such as a prefabricated cabin in coastal areas, moist air may cause dust to adhere more easily to the surface of the inclined dust baffle 1300. To solve this problem, a hydrophobic treatment can be adopted on the surface of the inclined dust baffle 1300, such as coating a nano-hydrophobic coating, so that dust is not easily attached, facilitating the smooth sliding of dust during the soot blowing process and maintaining the normal function of the inclined dust baffle 1300.

[0087] In some examples, such as Figures 6 - 13 shown, the inclined scraper 1400 is made of silicone rubber material with good elasticity and wear resistance. Silicone rubber can not only effectively abut against the filter element 500 while ensuring elasticity, scraping the dust on its surface, but also is not easily worn on the filter element 500 during long-term use. The inclined scraper 1400 is integrally long strip-shaped, and its length is adapted to the width of the filter element 500 to ensure that the entire width range of the filter element 500 can be covered. The inclination angle of the scraper is designed to form an angle of 15° - 30° with the surface of the filter element 500. This angle can not only ensure a good scraping effect on the dust by the scraper, but also will not cause excessive pressure on the filter element 500 to avoid damaging the filter element 500.

[0088] Inside the outer cover 800 of the prefabricated cabin, at the position opposite to the first soot blowing head 1101 and the second soot blowing head 1201, the inclined scraper 1400 is installed through a special elastic bracket. The elastic bracket is made of spring steel. One end is fixed to the inner wall of the outer cover 800, and the other end is connected to the inclined scraper 1400. The elasticity of the spring steel enables the inclined scraper 1400 to always maintain an elastic abutment against the filter element 500, ensuring that during the movement of the filter element 500, the scraper can closely fit the surface of the filter element 500 to scrape dust. At the same time, the elastic bracket also has a certain adjustment function, and the pressure between the inclined scraper 1400 and the filter element 500 can be finely adjusted by rotating nuts or other means to adapt to filter elements 500 of different materials and thicknesses.

[0089] The ash guide plate 1500 is made of galvanized steel sheet, has good corrosion resistance, and can be used for a long time in the prefabricated cabin environment. The ash guide plate 1500 is inclined, and its inclination direction is the same as the dust scraping direction of the inclined scraper 1400, and the inclination angle is about 45°. Such a design is conducive to guiding the dust scraped by the inclined scraper 1400 to slide down smoothly. The length and width of the ash guide plate 1500 are designed according to the size of the inclined scraper 1400 and the possible scattering range of dust to ensure that the dust scraped from the inclined scraper 1400 can be completely received.

[0090] The ash guide plate 1500 is installed on one side of the inclined scraper 1400 and fixed to the inner wall of the outer cover 800 by welding or bolting. During installation, it is necessary to ensure that the distance between the ash guide plate 1500 and the inclined scraper 1400 is appropriate, neither too close to prevent the scraped dust from smoothly falling into the ash guide plate 1500, nor too far to cause the dust to scatter. The coordination of the inclined scraper and the ash guide plate When the filter element 500 moves driven by the feeding roller 600 and the winding roller 700, the inclined scraper 1400 elastically abuts against the surface of the filter element 500 under the action of the elastic support, scraping off the dust on the filter element 500. The scraped dust, under the action of gravity and the pushing of the inclined scraper 1400, falls on the inclined ash guide plate 1500, and then slides down along the inclined surface of the ash guide plate 1500 to the ash collection area at the bottom of the prefabricated cabin for centralized cleaning. At the same time, the airflows blown by the first soot blowing head 1101 and the second soot blowing head 1201 will also assist in blowing some loose dust towards the inclined scraper 1400 direction, enhancing the dust scraping effect.

[0091] The setting of the inclined scraper 1400 and the ash guide plate 1500 further improves the cleaning efficiency of the filter element 500. The inclined scraper 1400 can directly contact the filter element 500, scraping off the stubbornly attached dust, and cooperating with the soot blowing function of the soot blowing pipe, making the cleaning of the filter element 500 more thorough. The ash guide plate 1500 effectively guides the dust to fall centrally.

[0092] In some examples, such as Figures 6 - 13 shown, a rotating turbine 1600 can also be added. The blades of the rotating turbine 1600 are twisted, and this design can more effectively capture the energy of the wind in the first soot blowing pipe 1100 and the second soot blowing pipe 1200, improving the energy conversion efficiency. The rotating turbine 1600 is installed at one end of the first soot blowing pipe 1100 and the second soot blowing pipe 1200 close to the filter element 500.

[0093] The first speed change gear set 1700 consists of a large gear and multiple small gears. The large gear is connected to the rotating shaft of the rotating turbine 1600, and the small gears are connected to the rotating shaft of the feeding roller 600 through different transmission ratios. Similarly, the large gear of the second speed change gear set 1800 is connected to the rotating shaft of the rotating turbine 1600, and the small gears are connected to the rotating shaft of the winding roller 700. By reasonably designing the tooth number ratio of the large and small gears, precise control of the rotational speeds of the feeding roller 600 and the winding roller 700 can be achieved. For example, when the filter element 500 needs to be replaced quickly, the rotational speeds of the feeding roller 600 and the winding roller 700 can be increased by adjusting the transmission ratio of the gear set; while when the filter element 500 needs to be cleaned finely, the rotational speed is reduced.

[0094] The variable speed gear set 1700 and the variable speed gear set 1800 are respectively installed on the fixed brackets inside the prefabricated cabin. The fixed brackets are welded by channel steel and have sufficient strength and stability to withstand the forces generated during the gear transmission process. The gear sets are connected to the rotating shafts of the rotating turbine 1600 and the feeding roller 600 and the winding roller 700 through couplings to ensure reliable torque transmission. At the same time, in order to ensure smooth gear transmission, a sealing cover is provided outside the gear sets, and an appropriate amount of lubricating oil is filled inside to play a role in lubrication and dust prevention.

[0095] When the first soot blowing pipe 1100 and the second soot blowing pipe 1200 blow air towards the filter element 500, the air pushes the rotating turbine 1600 to rotate. The rotating turbine 1600 drives the large gears in the variable speed gear set 1700 and the variable speed gear set 1800 to rotate through the rotating shaft. The large gears then drive the small gears to rotate through different transmission ratios, and further drive the feeding roller 600 and the winding roller 700 to rotate. Since the feeding roller 600 and the winding roller 700 respectively drive one end of the filter element 500, the filter element 500 will move under the action of the two, realizing a continuous cleaning process. At the same time, the change in the magnitude of the soot blowing air volume will cause the change in the rotation speed of the rotating turbine 1600. Through the adjustment of the variable speed gear set, the rotation speeds of the feeding roller 600 and the winding roller 700 will also change accordingly, so as to realize the function of automatically adjusting the moving speed of the filter element 500 according to the soot blowing intensity.

[0096] In some examples, in the internal space planning of the prefabricated cabin, the requirement that the rotating shaft of the rotating turbine 1600 is parallel to the rotating shaft of the feeding roller 600 is fully considered. When installing the first soot blowing pipe 1100 and the second soot blowing pipe 1200, their positions and angles need to be accurately calculated and adjusted. At the end of the soot blowing pipe close to the filter element 500, the rotating shaft of the rotating turbine 1600 is arranged horizontally and is parallel to the rotating shaft of the feeding roller 600 which is also horizontally arranged.

[0097] Since the rotating shaft of the rotating turbine 1600 is parallel to the rotating shaft of the feeding roller 600, the transmission structure can be simplified when designing the variable speed gear set 1700. The parallel setting of the rotating shaft of the rotating turbine 1600 and the rotating shaft of the feeding roller 600 makes the power transmission process smoother. Compared with the radial force and axial force that may be generated by non-parallel setting, parallel shaft transmission reduces unnecessary force interference, reduces the wear of gears and bearings, and extends the service life of the equipment. During the long-term operation process, parallel shaft transmission can maintain a stable transmission ratio, ensure that the feeding roller 600 and the winding roller 700 drive the filter element 500 to move at the expected speed, and ensure the stability and consistency of the cleaning process of the filter element 500.

[0098] The parallel rotation axis layout makes the installation and maintenance of the device more convenient. During the installation process, due to their parallel relationship, it is easier to position and calibrate, reducing the installation error. During maintenance, whether it is for repairing or replacing parts of the rotating turbine 1600, the first speed gear set 1700 or the feeding roller 600, the parallel layout provides a more open operating space for the operator, facilitating the use of tools and the disassembly and installation of parts, improving the maintenance efficiency and reducing the maintenance cost.

[0099] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present disclosure and not to limit them. Although the present disclosure has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present disclosure can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present disclosure, and they should all be covered within the scope of the claims of the present disclosure.
