A plate waste heat wastewater recycling equipment

Abstract

This invention discloses a waste heat recovery and reuse device for sheet metal, belonging to the field of wastewater treatment technology. It includes: a base, a cylindrical body fixedly installed at the center of the top of the base, a heat exchange component installed on the top of the cylindrical body, a filtration mechanism installed in the inner cavity of the cylindrical body, and a drain outlet installed inside the base. This waste heat recovery and reuse device for sheet metal includes a spiral cooling pipe that discharges the cooled wastewater to the top of a conical water guide platform. The conical water guide platform, by its shape, can evenly guide the wastewater onto an arc-shaped filter platform. There are five sets of arc-shaped filter platforms, so the wastewater flows sequentially from top to bottom onto the five sets of arc-shaped filter platforms. When the wastewater flows through the arc-shaped filter platforms, the filter tank filters the residue in the wastewater. Because the filtration width of the filter tank increases sequentially from top to bottom, the filter tank can filter residues of different sizes, improving the filtration efficiency.

Description

Technical Field

[0001] This invention relates to the field of wastewater treatment technology, specifically to a device for recycling and reusing waste heat from wood panels. Background Technology

[0002] The production of wood-based panels involves core processes such as hot pressing, wood steaming, and surface treatment, generating a large amount of industrial wastewater that carries significant waste heat. On one hand, the wastewater from panel production is complex, containing pollutants such as lignin, resin residues, suspended solids, hemicellulose degradation products, and small amounts of chemical additives (e.g., flame retardants, waterproofing agents). Direct discharge of this wastewater would severely damage the aquatic ecosystem and fail to meet national environmental emission standards. On the other hand, direct loss of waste heat from the wastewater would result in significant energy waste, contradicting the current trend of energy conservation and emission reduction in industry. Therefore, a waste heat recovery and reuse system for wood-based panels is needed.

[0003] Authorization announcement number CN219792750U discloses a waste heat recovery and reuse device for ALC board production, belonging to the field of wastewater treatment technology. This waste heat recovery and reuse device for ALC board production includes a treatment tank; a motor mounting base fixedly connected to the side of the treatment tank; a drive motor fixedly connected to the upper end of the motor mounting base; and a cleaning mechanism, which has two sets. Each set of the cleaning mechanism includes a limiting sleeve, a rotating rod, a gear, a rotating drum, and activated carbon blocks. There are two limiting sleeves and multiple activated carbon blocks. Each limiting sleeve is fixedly connected to the inner walls of both sides of the treatment box. Activated carbon blocks agitate the wastewater to adsorb non-settling high molecular weight compounds and organic matter in the wastewater to clean it. This device not only removes solid impurities from the wastewater but also effectively removes compounds and organic matter, allowing the purified wastewater to be reused after discharge. The device filters residues in the wastewater through filter holes in the filter plate. The filter plate contains a lot of residues in the wastewater, which can easily cause the filter holes to become clogged during use, requiring frequent cleaning, increasing the workload and reducing wastewater treatment efficiency. Summary of the Invention

[0004] The purpose of this invention is to provide a waste heat recovery and reuse device for board materials. When the wastewater flows through the arc-shaped filter platform, the filter tank will filter the residue in the wastewater.

[0009] Preferably, the slag removal assembly further includes an annular unloading platform, an unloading port, a telescopic rod, and a push plate.

A push plate is fixedly installed at the output end of the telescopic rod. The bottom of the push plate abuts against the top of the annular discharge platform.

[0010] Preferably, the slag removal assembly further includes a support plate and filter rollers. The support plate is fixedly installed between the two baffles. The surface of the support plate is provided with filter holes. The support plate is in contact with the inner side of the conveyor belt.

[0012] Compared with the prior art, the beneficial effects of the present invention are: the waste heat and wastewater recovery and reuse equipment for the plate material; 1. The spiral cooling pipes discharge the cooled wastewater to the top of the conical water guide platform. The conical water guide platform, by its own shape, can evenly guide the wastewater to the arc-shaped filter platform. There are five sets of arc-shaped filter platforms, so the wastewater will flow from top to bottom onto the five sets of arc-shaped filter platforms. When the wastewater flows through the arc-shaped filter platforms, the filter tank will filter the residue in the wastewater. Since the filtration width of the filter tank increases from top to bottom, the filter tank can filter residues of different sizes, thereby improving the filtration efficiency of residues. 2. The cone-shaped water guide platform rotates, which drives the arc-shaped filter cake platform and filter cake tank to rotate. When the cone-shaped water guide platform, arc-shaped filter cake platform and filter cake tank rotate, the cleaning plate will be attached to the surface of the cone-shaped water guide platform and arc-shaped filter cake platform to slide and clean the residue. Meanwhile, the cleaning rod will slide and clean the residue in the filter cake tank, which can improve the cleaning efficiency of the residue. 3. When the conveyor belt transports the residue to the bottom of the filter roller, the motor drives the filter roller to rotate through the pulley and belt. When the filter roller rotates, it presses the residue, squeezing out the wastewater inside. After the wastewater is squeezed out, it falls into the sedimentation tank through the filter holes on the conveyor belt and support plate. The filter roller and support plate are at an angle, which can press the residue tighter and squeeze out the wastewater inside the residue to the greatest extent, so that the wastewater inside the residue can be dried after the residue is filtered. 4. When wastewater falls into the sedimentation tank, the rotating hood drives the scraper to rotate against the inner wall of the sedimentation tank, sending the sediment to the bottom. When the sediment accumulates to a certain amount, the cylinder will push the baffle cylinder to move, causing the bottom slope to adhere to the inner wall of the sedimentation tank. At this time, the external sewage pump will start working. The sewage pump will discharge the wastewater and sediment inside the baffle cylinder through the sewage pipe. When the wastewater is transported, it can impact the sediment at the bottom of the sedimentation tank into the sewage pipe and then discharge it through the sewage pump. Thus, the sedimentation tank can reduce the outflow of wastewater during sewage discharge, and can be operated without stopping the machine, improving sewage discharge efficiency.

[0015] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0016] Furthermore, the terms "installation," "setup," "equipped with," "connection," "linking," and "socketing" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral structure; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium, or an internal connection between two devices, components, or parts. Those skilled in the art can understand the specific meaning of these terms in this application based on the specific circumstances.

[0017] Please see Figures 1-4 The present invention provides an embodiment of a waste heat recovery and reuse device for plate materials, comprising: a base 100, a cylinder 200 fixedly installed at the center of the top of the base 100, a heat exchange component 300 installed on the top of the cylinder 200, a filter mechanism 400 installed in the inner cavity of the cylinder 200, a drain outlet 500 installed inside the base 100, and the filter mechanism 400 including a slag removal component 410, a sedimentation component 420, and a filter layer 430; It should be noted that the wastewater enters the heat exchange component 300 for cooling. After cooling, the wastewater is transported to the cylinder 200 and treated by the filtration mechanism 400. The slag removal component 410 in the filtration mechanism 400 filters out larger residues in the wastewater. After the larger residues are filtered out, the wastewater enters the sedimentation component 420 to settle smaller particles in the water. After sedimentation, the wastewater falls into the lower part of the cylinder 200 and is purified by the filter layer 430 to meet the discharge standards. After purification, the wastewater can be discharged through the drain outlet 500.

[0018] like Figures 1-4 As shown, the heat exchange assembly 300 includes a cooling cylinder 310, a spiral cooling pipe 320, a heat exchange pipe 330, and a heat exchanger 340. The cooling cylinder 310 is installed on the top of the cylinder 200. The spiral cooling pipe 320 is installed through the interior of the cooling cylinder 310. The top end of the spiral cooling pipe 320 passes through the top of the cooling cylinder 310, and the bottom end of the spiral cooling pipe 320 passes through the bottom of the cooling cylinder 310 and the top of the cylinder 200. The center of the bottom end of the spiral cooling pipe 320 and the center of the cylinder 200 are on the same axis. The upper and lower parts of the outer surface of the cooling cylinder 310 are respectively equipped with water inlet and water outlet heat exchange pipes 330. The other end of the heat exchange pipe 330 is connected to the heat exchanger 340, and the heat exchanger 340 is installed on the top of the cylinder 200. It is conceivable that wastewater is transported from the inlet at the top of the spiral cooling pipe 320 to the outlet at the end. When the wastewater passes through the middle of the spiral cooling pipe 320, the coolant in the cooling cylinder 310 will cool the wastewater. While the coolant is cooling the wastewater, the lower heat exchange pipe 330 will transport the heated coolant to the heat exchanger 340, and the upper heat exchange pipe 330 will transport the cooled coolant from the heat exchanger 340 to the cooling cylinder 310. In this way, the coolant can continuously cool the wastewater, and the heat exchange pipe 330 can collect the waste heat of the wastewater.

[0019] like Figures 1-7 , Figure 10 As shown, the slag removal assembly 410 includes a conical water guide platform 411, an arc-shaped filter platform 412, a filter trough 413, a drain hole 414, a cleaning plate 416, and a cleaning rod 417. A rotatable conical water guide platform 411 is provided at the axial center of the upper part of the inner cavity of the cylinder 200. At least five sets of arc-shaped filter platforms 412 arranged from bottom to top are fixedly installed on the outer surface of the conical water guide platform 411. Each set of arc-shaped filter platforms 412 is distributed in a circular array on the outer surface of the conical water guide platform 411. Each arc-shaped filter platform 412 has at least... Three filter cake tanks 413, the filtration width of the filter cake tanks 413 increases from top to bottom with the height of the five sets of arc-shaped filter cake platforms 412. The conical water guide platform 411 has a drainage hole 414 on the inner side near the filter cake tank 413. The filter cake tank 413 is connected to the drainage hole 414. A matching cleaning rod 417 is movably installed inside the filter cake tank 413. A cleaning plate 416 is fixedly installed between the top of the cleaning rod 417 and the inner wall of the cylinder 200. One end of the cleaning plate 416 has an inclined surface that fits against the surface of the conical water guide platform 411. It is worth noting that the spiral cooling pipe 320 discharges the cooled wastewater to the top of the conical water guide platform 411. The conical water guide platform 411, through its shape, can evenly guide the wastewater onto the arc-shaped filter platform 412. The arc-shaped filter platform 412 has five sets, allowing the wastewater to flow from top to bottom onto it. As the wastewater flows through the arc-shaped filter platform 412, the filter trough 413 filters the residue in the wastewater. Because the filtration width of the filter trough 413 increases sequentially from top to bottom, it can filter residues of different sizes, improving efficiency. The filter has high filtration efficiency for residues. After the residues are filtered, the wastewater can be discharged through the drain hole 414. While the filter cake tank 413 is filtering the residues, the conical water guide platform 411 rotates through the components. When the conical water guide platform 411 rotates, it will drive the arc-shaped filter cake platform 412 and the filter cake tank 413 to rotate. When the filter cake tank 413 rotates, it will slide with the cleaning rod 417. When the cleaning rod 417 slides, it can clean the residue inside the filter cake tank 413. At the same time, the cleaning plate 416 will clean the surface of the arc-shaped filter cake platform 412 and the conical water guide platform 411.

[0020] like Figures 1-11 As shown, the slag removal assembly 410 also includes a water-blocking strip 415, a slag discharge trough 418, a baffle 419, a conveyor roller 4110, a conveyor belt 4111, a bevel gear set 4112, and a fixing rod 4122. A water-blocking strip 415 is fixedly installed on the side of the arc-shaped filter platform 412 near the cylinder 200. A slag discharge trough 418 is formed through the surface of the conical water guide platform 411 near the arc-shaped filter platform 412. Two baffles 419 are symmetrically fixedly installed at the ends of the slag discharge trough 418. Both the baffles 419 and the slag discharge trough 418 have rotating conveyor rollers 4122 inside. 110, a conveyor belt 4111 is rotatably connected between the conveyor rollers 4110. The surface of the conveyor belt 4111 is provided with water filter holes. A bevel gear set 4112 is installed on the top inner side of the conical water guide platform 411. A fixed rod 4122 is rotatably installed at the axial center of the top inner side of the conical water guide platform 411. The bevel gear set 4112 is connected to the conveyor rollers 4110 and the fixed rod 4122 respectively. The bevel gear set 4112 is usually composed of a first bevel gear, a second bevel gear, a third bevel gear, a fourth bevel gear, a rotating rod, and a bearing seat, etc. It is understood that when wastewater flows onto the arc-shaped filter platform 412 at the bottom of the conical guide platform 411, the baffle strip 415 can block the wastewater and residue, preventing them from flowing directly into the sedimentation tank 421. When the conical guide platform 411 rotates, the cleaning rod 417 and the cleaning plate 416 can push the residue on the filter trough 413 and the arc-shaped filter platform 412 into the slag discharge trough 418. When the residue enters the slag discharge trough 418, it will fall onto the conveyor belt 4111. At this time, when the conical guide platform 411 rotates, it will drive the rotating rod to rotate through the bearing seat. When the rotating rod rotates, it will drive the third bevel gear to rotate. The rotation of the third bevel gear can drive the... The four bevel gears mesh and rotate. When the third bevel gear meshes and rotates, it drives the second bevel gear to rotate via the rotating rod. When the second bevel gear rotates, it drives the first bevel gear to mesh and rotate. When the first bevel gear meshes and rotates, it drives the conveyor roller 4110 to rotate. When the conveyor roller 4110 rotates, it drives the conveyor belt 4111 to rotate. When the conveyor belt 4111 rotates, it drives the remaining conveyor rollers 4110 to rotate on the slag discharge trough 418 and the baffle 419. While the conveyor belt 4111 rotates, it can convey the residue. While conveying the residue, the conveyor belt 4111 can also discharge wastewater into the conical guide plate 427 through its own filter holes.

[0021] like Figures 1-11 As shown, the slag removal assembly 410 also includes a rotating cover 4113, a slag discharge port 4114, and a cleaning brush 4115. The rotating cover 4113 is rotatably installed on the inner wall of the cylinder 200. A driving component is connected to the outer surface of the rotating cover 4113. The driving component is usually composed of a motor, a reducer, and gears. The driving component is installed on the outer surface of the cylinder 200. The slag discharge port 4114 is opened through the inner wall of the rotating cover 4113 near the baffle 419 and the conveyor belt 4111. The slag discharge port 4114 is connected to the baffle 419. A cleaning brush 4115 is fixedly installed at the bottom of the slag discharge port 4114. The top of the cleaning brush 4115 abuts against the surface of the conveyor belt 4111. It should be understood that when the motor is working, it will drive the reducer to work. When the reducer is working, it can drive the gear to mesh and rotate. When the gear meshes and rotates, it will drive the rotating cover 4113 to rotate. When the rotating cover 4113 rotates, it can drive the conical water guide platform 411 to rotate through the baffle 419. When the conical water guide platform 411 rotates, it will drive the conveyor roller 4110 and the conveyor belt 4111 to rotate through the bevel gear set 4112. When the conveyor belt 4111 rotates, it can transport the residue into the interior of the rotating cover 4113 through the slag discharge port 4114. When the conveyor belt 4111 transports the residue into the interior of the slag discharge port 4114, the cleaning brush 4115 can clean the surface of the conveyor belt 4111, thereby preventing the residue from adhering to the conveyor belt 4111.

[0022] like Figures 1-7 , Figure 11 As shown, the slag removal assembly 410 also includes an annular unloading platform 4116, an unloading port 4117, a telescopic rod 4118, and a push plate 4119. The annular unloading platform 4116 is rotatably installed at the bottom of the rotating cover 4113. The side of the annular unloading platform 4116 is fixedly installed on the inner wall of the cylinder 200. The top of the annular unloading platform 4116 is an annular inclined surface. The unloading port 4117 is installed at the bottom of the lower side of the annular inclined surface. The end of the unloading port 4117 passes through the inner wall of the cylinder 200. The telescopic rod 4118 is fixedly installed at the top of the inner side of the rotating cover 4113. The push plate 4119 is fixedly installed at the output end of the telescopic rod 4118. The bottom of the push plate 4119 abuts against the top of the annular unloading platform 4116. It should be noted that when the rotating cover 4113 rotates, it will rotate on the annular unloading platform 4116. When the rotating cover 4113 rotates, it can drive the telescopic rod 4118 to rotate. When the telescopic rod 4118 rotates, it will drive the push plate 4119 to rotate. When the push plate 4119 rotates, it can always be in contact with the surface of the annular unloading platform 4116 through the cooperation of the telescopic rod 4118. When the push plate 4119 rotates, it can push the residue that falls onto the surface of the annular unloading platform 4116. When the residue is pushed to the upper part of the unloading port 4117, it can be discharged to the outside of the cylinder 200.

[0023] like Figures 4-11 As shown, the slag removal assembly 410 also includes a support plate 4120 and filter rollers 4121. The support plate 4120 is fixedly installed between two baffles 419. The surface of the support plate 4120 is provided with filter holes. The support plate 4120 is in contact with the inner side of the conveyor belt 4111. At least six filter rollers 4121 are rotatably installed between the two baffles 419. The six filter rollers 4121 are obliquely arranged between the two baffles 419 and are set at an angle with the support plate 4120. The end of the filter roller 4121 is connected to a driving component. The driving component is installed on the side of the baffle 419. The driving component can be composed of components such as a motor, belt and pulley. It is conceivable that when the conveyor belt 4111 transports the residue to the bottom of the filter roller 4121, the motor can drive the filter roller 4121 to rotate through the cooperation of the pulley and the belt. When the filter roller 4121 rotates, it will press the residue. When the residue is pressed, the wastewater inside can be squeezed out. After the wastewater inside the residue is squeezed out, it falls into the sedimentation tank 421 through the filter holes on the conveyor belt 4111 and the support plate 4120. Furthermore, the filter roller 4121 and the support plate 4120 are at an angle, so the residue can be pressed tighter and tighter to squeeze out the wastewater inside the residue to the greatest extent.

[0024] like Figures 1-7 , Figure 10As shown, the sedimentation assembly 420 includes a sedimentation tank 421, an overflow pipe 422, and a conical guide plate 427. The sedimentation tank 421 is fixedly installed in the middle of the inner cavity of the cylinder 200. The conical guide plate 427 is provided at the axial center of the inner side of the conical guide platform 411. The lower edge of the conical guide plate 427 is located inside the sedimentation tank 421. At least six overflow pipes 422 are installed in a ring array through the axial center of the inner side of the sedimentation tank 421. It is worth noting that after the wastewater is descaled, it can fall onto the conical guide plate 427 through the drain hole 414 and the slag discharge trough 418. The conical guide plate 427 can gently guide the wastewater into the sedimentation tank 421 for sedimentation through its own conical shape. After sedimentation, the wastewater can flow through the top of the overflow pipe 422 to the lower part of the cylinder 200.

[0025] like Figures 1-7 , Figure 10 As shown, the sedimentation assembly 420 also includes an overflow cylinder 423, a baffle cylinder 424, a cylinder 425, a connecting rod 426, a scraper 428, and a drain pipe 429. The top of the overflow pipe 422 is provided with an extension plate, the end of which is fixedly installed on the inner wall of the overflow cylinder 423. The overflow cylinder 423 is connected to the conical guide plate 427 via the connecting rod 426. The baffle cylinder 424 is movably installed on the inner side of the overflow cylinder 423, and a [missing information - likely a component or component] is fixedly installed on the top of the overflow cylinder 423. Cylinder 425, the telescopic end of cylinder 425 passes through overflow cylinder 423 and is connected to water baffle cylinder 424. The lower end of water baffle cylinder 424 is provided with an inclined surface. The inclined surface of water baffle cylinder 424 matches the inclined surface inside sedimentation tank 421. Scraper 428 is provided inside sedimentation tank 421. The end of scraper 428 is connected to rotating cover 4113. Sewage pipe 429 is installed at the end of sedimentation tank 421. The end of sewage pipe 429 passes through the inner wall of cylinder 200 and is connected to sewage pump. It is clear that when wastewater falls into the sedimentation tank 421, the rotation of the rotating cover 4113 will cause the scraper 428 to rotate against the inner wall of the sedimentation tank 421. When the scraper 428 rotates, it can send the sediment in the upper part of the sedimentation tank 421 to the bottom of the sedimentation tank 421. When the sediment in the sedimentation tank 421 accumulates to a certain amount, the cylinder 425 will push the baffle cylinder 424 to move. When the baffle cylinder 424 moves, it can slide downward against the inner wall of the overflow cylinder 423. When the baffle cylinder 424 slides to the designated position, the bottom is inclined. When the bottom of the baffle cylinder 424 is attached to the inner wall of the sedimentation tank 421, it can cover the sediment at the bottom of the sedimentation tank 421. At this time, the external sewage pump is started. The sewage pump works to discharge the wastewater and sediment inside the baffle cylinder 424 through the sewage pipe 429. When the wastewater is transported, it can impact the sediment at the bottom of the sedimentation tank 421 into the sewage pipe 429 and discharge it through the sewage pump. Thus, the sedimentation tank 421 can reduce the outflow of wastewater when discharging sewage, and can be operated without stopping the machine, thereby improving the sewage discharge efficiency.

[0026] like Figures 1-6 As shown, a filter layer 430 is installed in the lower part of the inner cavity of the cylinder 200; It should be understood that when the overflow pipe 422 discharges wastewater into the bottom of the cylinder 200, the wastewater will fall onto the filter layer 430. The filter layer 430 can intercept large organic molecules in the wastewater, such as proteins, polysaccharides, colloids, bacteria and viruses, while the filtered purified water can be discharged through the drain outlet 500.

[0027] The above are merely preferred embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
