Description

Technical Field

[0001] This invention relates to the field of construction equipment technology, and in particular to a formwork cleaning device for construction projects. Background Technology

[0002] In construction engineering, reusable formwork systems such as steel formwork and aluminum formwork are widely used due to their high forming precision and high turnover rate. However, after demolding, the surface of the formwork often retains release agent, cement slurry skin, concrete residue, and oil stains. If not thoroughly cleaned, these residues will directly affect the flatness, appearance, and structural durability of subsequent pours.

[0003] Currently, common cleaning methods in the industry mainly include manual handheld high-pressure water gun washing, wire brush grinding, or simple roller brush operation. These methods have the following drawbacks: manual washing is labor-intensive, inefficient, and easily affected by on-site water pressure and human factors, resulting in problems such as missed areas and uneven cleaning; wire brush or roller brush cleaning can easily scratch the template surface, reducing the template's lifespan, and also generating a large amount of dust, which is detrimental to the environment; existing equipment is mostly designed for single scenarios: complex geometric areas such as flat templates, joints, reinforcing ribs, bolt holes, and tongue and groove require different tools or multiple operations, resulting in poor versatility; wastewater generated during the cleaning process cannot be effectively collected, causing serious secondary pollution on-site and increasing subsequent cleaning costs; the equipment height is not adjustable, making it unable to adapt to templates of different thicknesses, resulting in cleaning blind spots or over-rinsing; traditional rigid connection structures vibrate greatly during reciprocating operations, easily causing structural fatigue, high noise, and difficult maintenance; therefore, a building template cleaning device for construction engineering is proposed. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a construction formwork cleaning device for building engineering.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A formwork cleaning device for construction engineering includes a support unit and a cleaning unit. The cleaning unit is slidably installed on the upper surface of the support unit. The cleaning unit includes a sliding gantry slidably installed on the upper surface of the support unit. Two sets of sliding gantry are connected in series through an installation box. A drive mechanism is arranged in the inner cavity of the installation box. A nozzle support plate is installed at the bottom of the drive mechanism. Preferably, the driving mechanism includes a drive motor installed at one end of the inner cavity of the mounting box, the outer ring of the drive motor is connected in series with the outer ring walls of multiple drive vertical cylinders via belts, a connecting cylinder is installed at the bottom of the drive vertical cylinder, and the lower end face of the connecting cylinder is connected to the nozzle support plate.

[0006] Preferably, the cleaning unit further includes an array of cleaning nozzles installed at the bottom of the nozzle support plate; when cleaning large-area flat steel formwork and aluminum formwork, the cleaning nozzles are laid in a honeycomb pattern on the bottom surface of the nozzle support plate, and the drive motor drives the drive cylinder to rotate at a low speed (3–10 r / min) through the belt; at this time, the landing point of each set of nozzle support plates is a concentric ring, and the ring spacing is determined by the rotation speed and the nozzle density. The overlapping area of ​​the rings formed is high and there is no blind spot; the large-area flat steel formwork and aluminum formwork being cleaned are left under constant water pressure for a long time, and the thin layer of release agent or light cement skin on the surface softens and then peels off.

[0007] Preferably, the cleaning nozzles are arranged horizontally at the bottom of the nozzle support plate; when cleaning the template seams, long reinforcing ribs and the frame, the cleaning nozzles are equidistantly arranged on the bottom surface of the nozzle support plate along a horizontal axis, with a moderate number; the drive motor drives the drive cylinder to rotate at a medium speed (10-30 r / min) through a belt, and the landing points of each cleaning nozzle form parallel circumferential lines, the spacing of which is determined by the nozzle spacing and the rotation speed; each circumferential line provides continuous high-pressure water jets, and the horizontal residue is "cut" away one by one, and the adjacent circumferential lines overlap by 10-15% by adjusting the rotation speed to avoid missed cleaning.

[0008] Preferably, cleaning nozzles are evenly distributed circumferentially on the bottom end face of the nozzle support plate, and an additional single cleaning nozzle is installed at the center position of the arrow-shaped structure formed by multiple sets of cleaning nozzles. When cleaning heavily contaminated areas with complex geometries such as bolt holes, corners, and air vents, most cleaning nozzles are evenly distributed on the bottom surface of the nozzle support plate with conical surfaces and the jet is inclined towards the center, with a single cleaning nozzle at the center pointing vertically downwards; the drive motor drives the drive cylinder to rotate at an adjustable uniform speed (5–20 r / min) via a belt; the circumferential cleaning nozzles form a cohesive spiral to push residual impurities towards the center, and the central cleaning nozzle forms a fixed-point impact circle to break and penetrate the accumulated layer, and the rotation causes the debris to be carried away by the water flow along the tangential direction.

[0009] Preferably, the sliding gantry includes a vertical arm and a positioning block installed at the top of the vertical arm. Two sets of guide optical shafts are vertically arranged in the inner cavity of the vertical arm. A lifting slider is sleeved on the outer ring of the guide optical shaft. Two sets of transmission sleeves are horizontally installed at the bottom of the vertical arm. A short rotating shaft is installed in the middle of the two sets of guide optical shafts. The two sets of vertical arms, which are slidably installed on both sides of the upper end face of the bearing unit, are connected in series by a connecting rod and friction scraper. The vertical arm is the main frame of the sliding gantry, and its inner cavity also serves as a "tool compartment" to temporarily store small components such as bolts and pins. The transmission sleeve at the bottom of the boom engages with the reciprocating guide rail; the positioning block extends downward through the top of the boom and connects to the rotating short shaft, providing vertical linear guidance for the lifting slider and bearing the radial load during rotation; the lifting slider is fitted onto the outer ring of the guide shaft and can float up and down, with its side end face tightly attached to the mounting box. By adjusting the height of the lifting slider on the guide shaft, the lifting of the mounting box is changed, thereby adjusting the cleaning height of the nozzle support plate and the cleaning nozzle to adapt to different working conditions; the inner ring of the transmission sleeve is fitted onto the outer ring of the transmission rod in the reciprocating guide rail, causing the sliding gantry to move back and forth along the reciprocating guide rail.

[0010] In non-cleaning conditions, the mounting box, drive mechanism, nozzle carrier plate, and cleaning nozzle are completely removed and replaced with a connecting rod friction scraper. The two ends of the connecting rod friction scraper are fixed to the two sets of vertical arms to ensure that the vertical arms on both sides move synchronously. The vertical arms and the connecting rod friction scraper make lateral reciprocating motion along the reciprocating guide rail. At this time, the bottom end of the connecting rod friction scraper is always in contact with the upper end of the wear-resistant pad. The thin layer of release agent and cement skin remaining on the template surface is directly scraped off by contact friction, without the need for an additional nozzle. The bottom end of the connecting rod friction scraper can be detachably attached with a wear-resistant rubber strip or wire brush for quick replacement after wear.

[0011] Preferably, the supporting unit includes an outer casing and an inner liner installed inside the outer casing. A template bracket is installed inside the inner liner, a wear-resistant pad is laid in the middle of the template bracket, and a lateral positioning component is installed at the edge of the inner wall of the template bracket. Reciprocating guide rails are laterally arranged on both sides of the upper edge of the outer casing, and a transmission sleeve is fitted onto the outer ring of a transmission rod arranged in the reciprocating guide rails. The outer casing is the outermost rigid shell of the supporting unit, serving as both a base and a wastewater collection tank, allowing the cleaned sludge to be directly stored in the tank to prevent further contamination on site. The inner liner is installed... Inside the outer casing of the equipment, the bottom plate is made into an inclined surface, so that the wastewater automatically collects at the low discharge port; the inner tank and the outer casing of the equipment are designed separately, and can be pulled out as a whole for cleaning or replacement, which greatly shortens the maintenance time; the template bracket directly supports the template to be cleaned, ensuring that the components are placed stably and without shaking, providing a precise benchmark for subsequent cleaning; the wear-resistant liner is laid in the center of the template bracket to buffer the impact of the template falling, avoid metal scratches, and at the same time reduce vibration and noise. The surface of the wear-resistant liner has transparent drainage holes, through which the wastewater during the cleaning process flows into the inner cavity of the inner tank and is discharged through the discharge port at the bottom of the side end face of the inner tank and the outer casing of the equipment.

[0012] Preferably, the lateral positioning assembly includes a fixing pin and a sliding sleeve sleeved to the outer ring of the fixing pin, a lateral connecting rod is installed on the side end face of the sliding sleeve, and a lateral support bracket is installed laterally at the other end of the lateral connecting rod. The lateral positioning component is located at the edge of the inner wall of the template bracket to limit the movement of the template from side to side during cleaning. The lateral positioning component consists of a fixing pin and a sliding sleeve. The sliding sleeve can slide on the fixing pin. The two sliding sleeves are connected to the transverse support frame by the lateral connecting rod. The upper end of the transverse support frame is used to support the template or component to be cleaned.

[0013] Preferably, the bearing unit further includes an elastic connector connecting the outer casing and the inner liner of the equipment, and three sets of rollers are arranged at the bottom of the inner cavity of the inner liner. The elastic connector is connected to the edge of the outer casing and the inner liner, which can absorb vibrations during equipment operation and avoid fatigue cracks caused by rigid connections.

[0014] Preferably, the bottom surface of the inner liner is inclined, and multiple sets of rollers of different diameters are arranged along the bottom of the inner cavity wall of the outer casing of the equipment. Three sets of rollers are evenly distributed at the bottom of the inner cavity of the outer casing of the equipment. The lower end surface of the outer casing of the equipment is slidably connected to the inner liner through the rollers. The three sets of rollers of different diameters are evenly distributed along the inclined bottom surface of the outer casing of the equipment, so that the inner liner can slide smoothly inside the outer casing of the equipment. The difference in roller diameter forms "multi-point support", which reduces friction and ensures that the force is evenly distributed on the entire platform, making pushing and pulling easier, and facilitating the quick removal of the inner liner for cleaning.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: Honeycomb nozzles and low-speed rotation enable large-area, blind-spot-free, and uniform cleaning, significantly improving the cleaning efficiency of flat templates; straight water jets and adjustable speed ensure 100% coverage of seam grooves, and high-pressure cutting reduces residue; arrow focusing and center point spraying "gather, crush, and fling away" heavily contaminated areas with complex geometry, thoroughly removing stubborn clumps.

[0016] In non-cleaning conditions, it is replaced with a connecting rod friction scraper to remove the release agent without water, saving water and reducing consumption. It is also functional. The outer shell and inner liner are separated with an inclined bottom, so sewage can be automatically collected and quickly extracted, reducing maintenance time by more than 50%. The lateral positioning component slide sleeve is linked, and the lateral limit of the template can be completed simultaneously by adjusting one side. It is easy to operate and has accurate positioning.

[0017] The elastic connectors absorb vibration, and the three sets of rollers with different diameters provide multi-point support, making the whole machine run more smoothly, easier to push and pull, and extending its service life. Attached Figure Description

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0021] Please refer to Figure 1-11 A construction formwork cleaning device for construction engineering includes a support unit 1 and a cleaning unit 2. The cleaning unit 2 is slidably installed on the upper end face of the support unit 1. The cleaning unit 2 includes a sliding gantry 21 slidably installed on the upper end face of the support unit 1. Two sets of sliding gantry 21 are connected in series through an installation box 22. A drive mechanism 23 is arranged in the inner cavity of the installation box 22. A nozzle support plate 24 is installed at the bottom of the drive mechanism 23. The drive mechanism 23 includes a drive motor 231 installed at one end of the inner cavity of the mounting box 22. The outer ring of the drive motor 231 is connected in series with the outer ring walls of multiple drive vertical cylinders 233 via belt 232. A connecting cylinder 234 is installed at the bottom of the drive vertical cylinder 233, and the lower end face of the connecting cylinder 234 is connected to the nozzle support plate 24.

[0022] Please refer to Figure 5 In Embodiment 1, the cleaning unit 2 further includes an array of cleaning nozzles 25 installed at the bottom of the nozzle support plate 24. When cleaning large-area flat steel and aluminum templates, the cleaning nozzles 25 are laid in a honeycomb pattern on the bottom surface of the nozzle support plate 24. The drive motor 231 drives the drive cylinder 233 to rotate at a low speed of 3–10 r / min via the belt 232. At this time, the landing point of each set of nozzle support plates 24 is a concentric ring, and the ring spacing is determined by the rotation speed and the nozzle density. The resulting ring overlap area is high and has no blind spots. When the large-area flat steel and aluminum templates being cleaned are kept under constant water pressure for a long time, the thin layer of release agent or light cement skin on the surface softens and then peels off.

[0023] Please refer to Figure 6 In a distinguishing embodiment 2, cleaning nozzles 25 are arranged horizontally at the bottom of the nozzle support plate 24. When cleaning the template seams, long reinforcing ribs, and edges, the cleaning nozzles 25 are equidistantly arranged along a horizontal axis on the bottom surface of the nozzle support plate 24, with a moderate number. The drive motor 231 drives the drive cylinder 233 to rotate at a medium speed (10–30 r / min) via the belt 232. The landing points of each cleaning nozzle 25 form parallel circumferential lines, and the spacing between the lines is determined by the nozzle spacing and the rotation speed. Each circumferential line provides continuous high-pressure water jets, and the horizontal residue is "cut" away one by one. By adjusting the rotation speed, adjacent circumferential lines overlap by 10–15% to avoid missed cleaning.

[0024] Please refer to Figure 7In a different embodiment, cleaning nozzles 25 are evenly distributed circumferentially on the bottom end face of the nozzle support plate 24. A single additional cleaning nozzle 25 is installed at the center of the arrow-shaped structure formed by multiple sets of cleaning nozzles 25. When cleaning heavily contaminated areas with complex geometries such as bolt holes, corners, and air vents, most of the cleaning nozzles 25 are evenly distributed on the bottom surface of the nozzle support plate 24 with conical surfaces and the jet stream tilted towards the center. The single central cleaning nozzle 25 points vertically downwards. The drive motor 231 drives the drive cylinder 233 to rotate at an adjustable, uniform speed (5–20 r / min) via a belt 232. The circumferential cleaning nozzles 25 form a cohesive spiral that pushes residual impurities towards the center, while the central cleaning nozzle 25 forms a fixed-point impact circle that breaks down and penetrates the accumulated layer. The rotation causes the debris to be carried away by the water flow tangentially.

[0025] Please refer to Figure 2 and Figure 3 Embodiment 4 is proposed, in which the sliding gantry 21 includes a vertical arm 211 and a positioning block 212 installed at the top of the vertical arm 211. Two sets of guide optical shafts 213 are vertically arranged in the inner cavity of the vertical arm 211. A lifting slider 214 is sleeved on the outer ring of the guide optical shafts 213. Two sets of transmission sleeves 215 are horizontally installed at the bottom of the vertical arm 211. A rotating short shaft 216 is installed in the middle of the two sets of guide optical shafts 213. The two sets of vertical arms 211, which are slidably installed on both sides of the upper end face of the bearing unit 1, are connected in series by a connecting rod friction scraper 217. The vertical arm 211 is the main frame of the sliding gantry 21, and its inner cavity also serves as a "tool compartment" to temporarily store small components such as bolts and pins. The transmission sleeve 215 at the bottom of the 11 engages with the reciprocating guide rail 18; the positioning block 212 extends downward through the top of the upright arm 211 and connects with the rotating short shaft 216, providing vertical linear guidance for the lifting slider 214 and bearing the radial load during rotation; the lifting slider 214 is fitted on the outer ring of the guide optical shaft 213 and can float up and down, with its side end face tightly attached to the mounting box 22. By adjusting the height of the lifting slider 214 on the guide optical shaft 213, the lifting of the mounting box 22 is changed, thereby adjusting the cleaning height of the nozzle carrier plate 24 and the cleaning nozzle 25 to adapt to different working conditions; the inner ring of the transmission sleeve 215 is fitted onto the outer ring of the transmission rod in the reciprocating guide rail 18, causing the sliding gantry 21 to move back and forth along the reciprocating guide rail 18.

[0026] Please refer to Figure 2In a different embodiment 5, under non-cleaning conditions, the mounting box 22, drive mechanism 23, nozzle support plate 24, and cleaning nozzle 25 are completely removed and replaced with a connecting rod friction scraper 217. The two ends of the connecting rod friction scraper 217 are fixedly connected to two sets of upright arms 211 to ensure that the upright arms 211 move synchronously on both sides. The upright arms 211 and the connecting rod friction scraper 217 move laterally and reciprocally along the reciprocating guide rail 18. At this time, the bottom surface of the connecting rod friction scraper 217 is always in contact with the upper surface of the wear-resistant pad 14, and the thin layer of release agent and cement skin remaining on the template surface is directly scraped off by contact friction, without the need for an additional nozzle. The bottom surface of the connecting rod friction scraper 217 can be detachably pasted with wear-resistant rubber strips or wire brushes, which can be quickly replaced after wear.

[0027] Please refer to Figure 8 and Figure 9 Embodiment 6 is proposed, wherein the supporting unit 1 includes an outer casing 11 and an inner liner 12 installed inside the cavity of the outer casing 11. A template bracket 13 is installed inside the cavity of the inner liner 12, a wear-resistant pad 14 is laid in the middle of the template bracket 13, and a lateral positioning component 15 is installed at the edge of the inner wall of the template bracket 13. Reciprocating guide rails 18 are arranged laterally on both sides of the upper edge of the outer casing 11, and a transmission sleeve 215 is sleeved on the outer ring of the transmission rod arranged in the reciprocating guide rail 18. The outer casing 11 is the outermost rigid shell of the supporting unit 1, which serves as both a base and a sewage collection tank, allowing the cleaned sludge to be directly stored in the tank to prevent re-contamination on site; the inner liner 12 Installed inside the outer casing 11 of the equipment, its bottom plate is made into an inclined surface, so that the sewage automatically collects to the low-level discharge port; the inner tank 12 is designed separately from the outer casing 11 of the equipment, and can be pulled out as a whole for cleaning or replacement, which greatly shortens the maintenance time; the template bracket 13 directly supports the template to be cleaned, ensuring that the components are placed stably and do not shake, providing a precise benchmark for subsequent cleaning; the wear-resistant liner 14 is laid in the center of the template bracket 13 to buffer the impact of the template falling, avoid metal scratches, and at the same time reduce vibration and noise. The surface of the wear-resistant liner 14 has transparent drainage holes, through which the wastewater during the cleaning process flows into the inner cavity of the inner tank 12 and is discharged through the discharge port at the bottom of the side end face of the inner tank 12 and the outer casing 11 of the equipment.

[0028] The lateral positioning assembly 15 includes a fixing pin 151 and a sliding sleeve 152 sleeved on the outer ring of the fixing pin 151. A lateral connecting rod 153 is installed on the side end face of the sliding sleeve 152, and a transverse support bracket 154 is installed laterally on the other end of the lateral connecting rod 153. Please refer to Figure 10In Embodiment 7, a lateral positioning component 15 is disposed at the edge of the inner cavity wall of the template bracket 13 for lateral positioning to prevent the template from moving left and right during the cleaning process. The lateral positioning component 15 consists of a fixing pin 151 and a sliding sleeve 152. The sliding sleeve 152 can slide on the fixing pin 151. The two sliding sleeves are connected to the transverse support frame 154 by the lateral connecting rod 153. The upper end face of the transverse support frame 154 is used to support the template or component to be cleaned.

[0029] Please refer to Figure 11 In embodiment 8, the supporting unit 1 further includes an elastic connector 16 connecting the outer casing 11 and the inner liner 12. Three sets of rollers 17 are arranged at the bottom of the inner cavity of the inner liner 12. The elastic connector 16 is connected to the edge of the outer casing 11 and the inner liner 12, which can absorb the vibration during equipment operation and avoid fatigue cracks caused by rigid connection.

[0030] Please refer to Figure 11 In a distinguishing embodiment 9, the bottom surface of the inner liner 12 is inclined. Multiple sets of rollers 17 of different diameters are arranged along the bottom of the inner cavity wall of the outer casing 11. Three sets of rollers 17 are evenly distributed at the bottom of the inner cavity of the outer casing 11, and the lower end surfaces of the outer casing 11 and the inner liner 12 are slidably connected by the rollers 17. The three sets of rollers 17 of different diameters are evenly arranged along the inclined bottom surface of the outer casing 11, allowing the inner liner 12 to slide smoothly within the outer casing 11. The difference in the diameter of the rollers 17 forms "multi-point support," which reduces friction and ensures uniform force distribution across the entire platform, making pushing and pulling easier and facilitating quick removal of the inner liner for cleaning. The above is the complete working principle of this invention.

[0031] In summary: When cleaning large-area flat steel and aluminum formwork, the cleaning nozzles 25 are laid in a honeycomb pattern on the bottom surface of the nozzle support plate 24. The drive motor 231 drives the drive cylinder 233 to rotate at a low speed of 3–10 r / min via the belt 232. At this time, the landing point of each set of nozzle support plates 24 is a concentric ring, and the ring spacing is determined by the rotation speed and the nozzle density. The resulting ring overlap area is high and there are no blind spots. When the large-area flat steel and aluminum formwork being cleaned is kept under constant water pressure for a long time, the thin layer of release agent or light cement skin on the surface softens and then peels off.

[0032] When cleaning the template seams, long reinforcing ribs and edges, the cleaning nozzles 25 are arranged equidistantly on the bottom surface of the nozzle support plate 24 along a horizontal axis, with a moderate number; the drive motor 231 drives the drive cylinder 233 to rotate at a medium speed (10–30 r / min) through the belt 232. The landing points of each cleaning nozzle 25 form parallel circumferential lines, and the spacing between the lines is determined by the nozzle spacing and the rotation speed; each circumferential line provides continuous high-pressure water jets, and the transverse residue is "cut" away one by one. By adjusting the rotation speed, the adjacent circumferential lines overlap by 10–15% to avoid missed cleaning.

[0033] When cleaning heavily contaminated areas with complex geometries such as bolt holes, corners, and air vents, most cleaning nozzles 25 are evenly distributed on the bottom surface of the nozzle support plate 24 with conical surfaces and the jet is inclined towards the center, with the central single cleaning nozzle 25 pointing vertically downwards; the drive motor 231 drives the drive cylinder 233 to rotate at an adjustable uniform speed (5–20 r / min) through the belt 232; the circumferential cleaning nozzles 25 form a cohesive spiral to push the residual impurities towards the center, and the central cleaning nozzle 25 forms a fixed-point impact circle to break and penetrate the accumulated layer, and the rotation causes the debris to be carried away by the water flow along the tangential direction.

[0034] The upright arm 211 is the main frame of the sliding gantry 21, and its inner cavity also serves as a "tool compartment" to temporarily store small components such as bolts and pins. The transmission sleeve 215 at the bottom of the upright arm 211 cooperates with the reciprocating guide rail 18. The positioning block 212 extends downward through the top of the upright arm 211 and is connected to the rotating short shaft 216, providing vertical linear guidance for the lifting slider 214 and bearing the radial load during rotation. The lifting slider 214 is fitted on the outer ring of the guide optical shaft 213 and can float up and down. Its side end face is in close contact with the mounting box 22. By adjusting the height of the lifting slider 214 on the guide optical shaft 213, the lifting of the mounting box 22 is changed, thereby adjusting the cleaning height of the nozzle carrier plate 24 and the cleaning nozzle 25 to adapt to different working conditions. The inner ring of the transmission sleeve 215 is fitted into the outer ring of the transmission rod in the reciprocating guide rail 18, so that the sliding gantry 21 moves back and forth along the reciprocating guide rail 18.

[0035] In non-cleaning conditions, the mounting box 22, drive mechanism 23, nozzle support plate 24, and cleaning nozzle 25 are removed as a whole and replaced with connecting rod friction scraper 217. The two ends of the connecting rod friction scraper 217 are fixedly connected to the two sets of upright arms 211 to ensure that the upright arms 211 on both sides move synchronously. The upright arms 211 and the connecting rod friction scraper 217 move laterally and reciprocally along the reciprocating guide rail 18. At this time, the bottom surface of the connecting rod friction scraper 217 is always in contact with the upper surface of the wear-resistant pad 14. The thin layer of release agent and cement skin remaining on the template surface is directly scraped off by contact friction, without the need for an additional nozzle. The bottom surface of the connecting rod friction scraper 217 can be detachably pasted with wear-resistant rubber strips or wire brushes for quick replacement after wear.

[0036] The outer casing 11 is the outermost rigid shell of the bearing unit 1, serving as both a base and a wastewater collection tank. It allows the cleaned sludge to be directly stored inside, preventing further contamination. The inner tank 12 is installed inside the outer casing 11, with its bottom plate angled to allow wastewater to automatically collect at a lower discharge point. The inner tank 12 is designed separately from the outer casing 11, allowing for complete removal for cleaning or replacement, significantly reducing maintenance time. The template support 13 directly supports the template to be cleaned, ensuring stable placement and preventing wobbling, providing a precise reference for subsequent cleaning. A wear-resistant pad 14 is laid in the center of the template support 13, cushioning the impact of falling templates, preventing metal scratches, and reducing vibration and noise. The wear-resistant pad 14 has permeable perforations on its surface, allowing wastewater to flow through these perforations into the inner tank 12 and out through the discharge port at the bottom of the side end face of the inner tank 12 and the outer casing 11.

[0037] The lateral positioning component 15 is located at the edge of the inner cavity wall of the template bracket 13 and is used for lateral positioning to prevent the template from moving left and right during the cleaning process. The lateral positioning component 15 consists of a fixing pin 151 and a sliding sleeve 152. The sliding sleeve 152 can slide on the fixing pin 151. The two sliding sleeves are connected to the transverse support frame 154 by the lateral connecting rod 153. The upper end face of the transverse support frame 154 is used to support the template or component to be cleaned.

[0038] The elastic connector 16 is connected to the edge of the outer casing 11 and the inner liner 12 of the equipment. It can absorb the vibration during equipment operation and avoid fatigue cracks caused by rigid connection.

[0039] Three sets of rollers 17 of different diameters are evenly arranged along the bottom inclined surface of the outer casing 11 of the equipment, so that the inner liner 12 can slide smoothly inside the outer casing 11 of the equipment. The difference in diameter of the rollers 17 forms "multi-point support", which reduces friction and ensures that the force is evenly distributed on the entire platform, making pushing and pulling easier, and at the same time facilitating the quick removal of the inner liner for cleaning.
