Description

Technical Field

[0001] The present invention belongs to the technical field of environmental protection drying, and specifically relates to a drying device and method for environmental protection. Background Art

[0002] Dryers are mainly used in departments such as mineral processing, building materials, metallurgy, and chemical industry to dry materials with a certain humidity or particle size. Dryers have strong adaptability to materials, can dry various materials, and the equipment is simple and reliable to operate, so they are widely used. They can be widely applied to the drying of materials in the coal industry such as slime, raw coal, flotation clean coal, and blended clean coal; the drying of materials in the building industry such as blast furnace slag, clay, bentonite, limestone, sand, and quartz stone; the drying of materials in the mineral processing industry such as various metal concentrates, waste residues, and tailings; and the drying of non-thermosensitive materials in the chemical industry. Among them, limestone is a common carbonate mineral, and its main component is calcium carbonate (CaCO 3 )). The drying process usually involves high-temperature heating, which causes the moisture on the surface of limestone to evaporate. During this process, impurities and fine particles in the limestone may be carried away by the hot air flow, forming dust. In addition, the operation of the drying equipment will also generate certain mechanical vibrations, which may further cause the fine particles in the limestone to fall off, increasing the generation of dust.

[0013] An environmental protection drying method, the specific operation method is as follows: S1. The limestone can be put in by opening the machine door of the dryer. Then, start the motor of the forward and reverse rotation type on the frame, so that it drives the rotating rod and the mesh plate fixedly installed on the rotating rod to rotate synchronously. Thus, the passively rotating mesh plate will scoop up the limestone in the dryer, and the limestone will naturally fall during the rotation. S2. The rotation of the rotating rod will also drive the meshing components to rotate mutually. When the spiral disc rod rotates forward passively, it will first drive the sleeve plate and then indirectly drive the corrugated pipe to translate and extend. Thus, the suction force generated by the translation and extension of the corrugated pipe will suck the gas in the dryer through the cylindrical groove and the rectangular filter pipe. During one reciprocation of the corrugated pipe, the gas will exert a force on the rectangular groove plate in the rectangular filter pipe. And the cross installation of the two rectangular groove plates will make the gas repeatedly contact the surface of the rectangular groove plate. Thus, it receives the heat emitted by the heating plate in the rectangular groove plate, and the temperature of the gas rises. S3. The passively driven sleeve plate will also drive the fixedly installed U-shaped plate to translate synchronously. In this way, the U-shaped plate can drive the arc angle plate to contact and squeeze the two elastic telescopic rods, so that it drives the rubber plate to move downward synchronously, generating a squeezing force in the trough plate box and the U-shaped liquid plate, squeezing the water body entering the U-shaped liquid plate through the liquid hopper and spraying it out from a plurality of atomizing nozzles, thereby performing dust reduction.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: (1) In the present invention, the limestone can be put in by opening the machine door of the dryer. Then, start the motor of the forward and reverse rotation type on the frame, so that it drives the rotating rod and the mesh plate fixedly installed on the rotating rod to rotate synchronously. Thus, the passively rotating mesh plate will scoop up the limestone in the dryer, and the limestone will naturally fall during the rotation. In this way, it is convenient to generate a dust-raising effect on the dust it carries. (2) The rotation of the rotating rod of the present invention will also synchronously drive the meshing components to rotate mutually. When the spiral disc rod rotates forward passively, it will first drive the sleeve plate and then indirectly drive the corrugated pipe to translate and extend. Thus, the suction force generated by the translation and extension of the corrugated pipe will pass through the cylindrical groove and the rectangular filter pipe to suck the gas in the dryer. During one reciprocating process of the corrugated pipe, the gas will exert a force on the rectangular groove plate in the rectangular filter pipe, and the cross installation of the two rectangular groove plates will make the gas repeatedly contact the surface of the rectangular groove plate. Thus, the gas will receive the heat radiated by the heating plate in the rectangular groove plate, causing the temperature of the gas to rise. After being squeezed back into the dryer, it will have an additional heating and drying effect on the limestone in the dryer. (3) The passive sleeve plate of the present invention will also drive the fixedly installed U-shaped plate to translate synchronously. In this way, the U-shaped plate can drive the arc-shaped plate to contact and squeeze the two elastic telescopic rods, causing them to drive the rubber plate to move downward synchronously, generating a squeezing force in the groove plate box and the U-shaped liquid plate, and squeezing the water body entering the U-shaped liquid plate through the liquid hopper and spraying it out from multiple atomizing nozzles, thereby achieving dust suppression for the dust.

[0017] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0018] As Figures 1 to 9 shown, the present invention provides an environmental protection drying device, including a dryer 1. One end of the top of the dryer 1 is hinged with a machine door 11. One side of the top end of the machine door 11 is fixedly connected through a one-way valve pipe for air intake. Both sides of the bottom end of the dryer 1 are tightly clamped with discharge plugs 12. A drying and dust removal section 2 is provided on the dryer 1. The drying and dust removal section 2 includes a frame 21 fixedly connected to the outer wall of one end of the dryer 1. A motor 22 of a forward and reverse rotation type is fixedly connected to the plate body of the frame 21. A rotating rod 23 is fixedly connected to the rotating shaft of the motor 22. The rod body of the rotating rod 23 is specifically rotationally connected through the body of the dryer 1, and a mesh plate 24 is also fixedly connected to the rod body of the rotating rod 23. A rectangular groove 26 is opened in the other end plate body of the dryer 1, and a sieve plate 25 is fitted and clamped in the inner wall of the rectangular groove 26. A meshing piston structure is specifically provided on the rod body of the rotating rod 23, and a dust reduction structure is also provided on the other end plate body of the dryer 1.

[0019] Adopting the above solution: By opening the machine door 11 on the dryer 1, limestone can be put in. Then, start the motor 22 of the forward and reverse rotation type on the frame 21 to drive the rotating rod 23 and the mesh plate 24 fixedly installed on the rotating rod 23 to rotate synchronously. Thus, the passively rotating mesh plate 24 will scoop up the limestone in the dryer 1, and the limestone will naturally fall during the rotation process, which is convenient for generating a dust-raising effect on the dust it carries.

[0020] The meshing piston structure includes a meshing component 27 provided on the rod body of the rotating rod 23. The meshing component 27 is specifically composed of a first gear and a second gear meshed with it. The diameter of the second gear is smaller than that of the first gear. A rotating wheel 28 is movably sleeved on the second gear. Clamping blocks 29 are fixedly connected to the outer walls of the upper and lower ends of the rotating wheel 28. Clamping grooves 230 for respectively clamping with the two clamping blocks 29 are provided in the inner walls of the upper and lower ends of the second gear. A spiral disc rod 231 is fixedly connected in the rotating wheel 28. A first torsion spring 232 is fixedly connected jointly between the spiral disc rod 231 and the frame 21. A sleeve plate 233 is threadedly connected to a side rod body of the spiral disc rod 231. Guide rods 2331 are respectively slidably connected to both ends of the sleeve plate 233. The rod bodies of the spiral disc rod 231 and the two guide rods 2331 are movably sleeved on the plate body of the frame 21. Three corrugated pipes 234 are fixedly connected to the sleeve plate 233. The other ends of the three corrugated pipes 234 are fixedly connected to the outer wall of one end of the dryer 1. And rectangular filter pipes 235 are correspondingly fixedly connected in the dryer 1 where the three corrugated pipes 234 are located. A cylindrical groove is correspondingly and penetratingly provided in the inner wall of the dryer 1.

[0021] With the above scheme: The rotation of the rotating rod 23 will also drive the meshing component 27 to rotate mutually. The teeth on the first gear are perfectly meshed with the teeth on the second gear. Since the diameter of the first gear is much larger than that of the second gear, when the two are no longer meshed, their smooth parts will press against each other, causing the second gear to be fixed at a point. Furthermore, during the rotation of the second gear, the rotating wheel 28 and the spiral disc rod 231 will be driven to rotate synchronously, thereby driving the first torsion spring 232 to generate passive deformation. When the first gear and the second gear are no longer meshed, the limiting force on the rotating wheel 28 decreases. At this time, driven by the deformed first torsion spring 232, the rotating wheel 28 can drive the two clamping blocks 29 to intermittently disengage from the corresponding clamping grooves 230 repeatedly, and drive the spiral disc rod 231 to rotate in the reverse direction. Thus, when the spiral disc rod 231 rotates forward, it drives the corrugated pipe 234 to translate and extend, and when it rotates in the reverse direction, it drives the corrugated pipe 234 to translate and contract. When the spiral disc rod 231 rotates forward passively, it will first drive the sleeve plate 233 and then indirectly drive the corrugated pipe 234 to translate and extend. Its moving process will be guided and translated through the guide rods 2331 on both sides of the sleeve plate 233.

[0022] Two U-shaped rods 236 are crosswise fixedly connected to the inner walls of both ends of the rectangular filter pipe 235. Two rectangular groove plates 237 are rotatably connected to the two groups of U-shaped rods 236. Heating plates 238 are fixedly connected to the inner walls of the two groups of rectangular groove plates 237. And a pressing plate 239 can be intermittently attached to the outer walls of both ends of each rectangular groove plate 237. Each group of pressing plates 239 is fixedly connected to the inner walls of both ends of the rectangular filter pipe 235 respectively.

[0023] Adopting the above solution: The suction force generated by the translational extension of the corrugated pipe 234 will pass through the cylindrical groove and the rectangular filter pipe 235 to suck the gas in the dryer 1. During one reciprocating process of the corrugated pipe 234, the gas will exert a force on the rectangular groove plate 237 in the rectangular filter pipe 235. And the cross-installation of the two groups of rectangular groove plates 237 will cause the gas to repeatedly come into surface contact with the rectangular groove plate 237, thereby receiving the heat dissipated by the heating plate 238 in the rectangular groove plate 237, raising the temperature of the gas. Then, after being squeezed back into the dryer 1, it will have an additional heating and drying effect on the limestone in the dryer 1.

[0024] The dust-removing structure includes a U-shaped plate 240 fixedly connected to the outer wall of the sleeve plate 233. The U-shaped plate 240 is also connected in a penetrating and sliding manner with the screw disc rod 231 and the guide rod 2331. A corner plate 241 is fixedly connected to the outer wall of the bottom end of the U-shaped plate 240. A groove plate box 242 is fixedly attached to the outer wall of the other end of the dryer 1. A liquid hopper 243 is fixedly connected in a penetrating manner to one side wall of the groove plate box 242. Two elastic telescopic rods 244 are connected in a penetrating and sliding manner to the top of the groove plate box 242. And the bottom ends of the elastic members on the two elastic telescopic rods 244 are fixedly connected to the outer wall of the top of the groove plate box 242. The outer wall of the bottom end of the corner plate 241 can be in intermittent fitting and sliding connection with the outer walls of the top ends of the two elastic telescopic rods 244. A partition 2421 is fixedly connected to the inner wall of the groove plate box 242 near the top. And an arc-shaped rod plate 2422 is rotatably connected to the inner wall of the groove plate box 242. Two torsion springs II 2423 are fixedly connected to the outer walls of the two ends of the arc-shaped rod plate 2422 near the top. The other ends of the two torsion springs II 2423 are respectively fixedly connected to the inner walls of the two ends of the groove plate box 242. A check valve pipe II for air outlet is fixedly connected in a penetrating manner to the plate body of the groove plate box 242. A rubber plate 245 is jointly fixedly connected to the bottom ends of the two elastic telescopic rods 244. A U-shaped liquid plate 246 is in fitting and sliding connection with the outer wall of the rubber plate 245. A plurality of atomizing nozzles 247 are fixedly connected in a penetrating manner to the bottom plate body of the U-shaped liquid plate 246. An aggregate drawer 248 is connected in a penetrating and fitting and sliding manner to one inner wall of the groove plate box 242. The top end of the U-shaped liquid plate 246 is fixedly connected to the inner wall of the top of the groove plate box 242.

[0025] Adopting the above solution: The passive sleeve plate 233 will also drive the fixedly installed U-shaped plate 240 to translate synchronously. In this way, the U-shaped plate 240 can drive the corner plate 241 to contact and squeeze the two elastic telescopic rods 244, causing them to drive the rubber plate 245 to move down synchronously, generating a squeezing force in the groove plate box 242 and the U-shaped liquid plate 246, squeezing the water body entering the U-shaped liquid plate 246 through the liquid hopper 243 and spraying it out from the plurality of atomizing nozzles 247, thereby realizing the dust removal, facilitating collection and subsequent cleaning. When the corrugated pipe 234 ejects impact gas and enters the sieve plate 25, it will first impact and drive the arc-angle rod plate 2422 that fits the sieve plate 25, causing it to passively rotate in the reverse direction under its own inclination, generating a reverse inclination state, thereby driving the second torsion spring 2423 to deform. As a result, it cannot form an occlusion and sealing state for the groove plate box 242 with the partition plate 2421, the sieve plate 25, and the arc-angle rod plate 2422. Thus, the gas containing dust will enter the groove plate box 242 for dust reduction.

[0026] An environmental protection drying method, the specific operation method is as follows: S1. By opening the machine door 11 on the dryer 1, limestone can be put in. Then, start the motor 22 of the forward and reverse rotation type on the frame 21, so that it drives the rotating rod 23 and the mesh plate 24 fixedly installed on the rotating rod 23 to rotate synchronously. Thus, the passively rotating mesh plate 24 will scoop up the limestone in the dryer 1, and the limestone will naturally fall during the rotation, which is convenient for generating a dust-raising effect on the dust it contains. S2. The rotation of the rotating rod 23 will also drive the meshing assembly 27 to rotate mutually. When the spiral disc rod 231 rotates forward passively, it will first drive the sleeve plate 233 and then indirectly drive the corrugated pipe 234 to translate and extend. Thus, the suction force generated by the translation and extension of the corrugated pipe 234 will suck the gas in the dryer 1 through the cylindrical groove and the rectangular filter pipe 235. During a reciprocating process of the corrugated pipe 234, the gas will exert a force on the rectangular groove plate 237 in the rectangular filter pipe 235, and the cross installation of the two rectangular groove plates 237 will cause the gas to repeatedly contact the surface of the rectangular groove plate 237. Thus, it receives the heat emitted by the heating plate 238 in the rectangular groove plate 237, causing the temperature of the gas to rise. S3. The passively moving sleeve plate 233 will also drive the fixedly installed U-shaped plate 240 to translate synchronously. In this way, the U-shaped plate 240 can drive the arc-shaped plate 241 to contact and squeeze the two elastic telescopic rods 244, causing them to drive the rubber plate 245 to move downward synchronously, generating a squeezing force in the groove plate box 242 and the U-shaped liquid plate 246, and squeezing the water body that enters the U-shaped liquid plate 246 through the liquid funnel 243 to be sprayed out from multiple atomizing nozzles 247, thereby performing dust reduction.

[0027] It should be added that: The heating plate 238 is a safe and reliable electric heating flat plate that generates heat on the plate surface after being powered on, is not charged and has no open flame, has a circular or square shape, and has high thermal efficiency because it mainly relies on heat conduction during use.

[0028] The working principle and usage process of the present invention: By opening the door 11 on the dryer 1, limestone can be put in. Then, start the motor 22 of the forward and reverse rotation type on the frame 21, which drives the rotating rod 23 and the mesh plate 24 fixedly installed on the rotating rod 23 to rotate synchronously. Thus, the mesh plate 24 that rotates passively will scoop up the limestone in the dryer 1, and the limestone will naturally fall during the rotation process, which is convenient for generating a dust-raising effect on the dust it carries. At the same time, the rotation of the rotating rod 23 will also drive the meshing assembly 27 to rotate mutually. The teeth on the first gear are perfectly meshed with the teeth on the second gear. Because the diameter of the first gear is much larger than that of the second gear, when the two are no longer meshed, their smooth parts will press against each other, causing the second gear to remain stationary at a fixed point. Then, during the rotation of the second gear, it will drive the runner 28 and the spiral rod 231 to rotate synchronously, thereby driving the torsion spring 1 232 to generate passive deformation. When the first gear and the second gear are no longer meshed, the force limiting the runner 28 decreases. At this time, driven by the deformed torsion spring 1 232, the runner 28 can drive the two clamping blocks 29 to intermittently disengage from the corresponding card slots 230 repeatedly, and drive the spiral rod 231 to rotate in the reverse direction. Thus, when the spiral rod 231 rotates forward, it drives the corrugated pipe 234 to translate and extend, and when it rotates in the reverse direction, it drives the corrugated pipe 234 to translate and contract. When the spiral rod 231 rotates forward passively, it will first drive the sleeve plate 233 and then indirectly drive the corrugated pipe 234 to translate and extend. Its movement process will be guided and translated through the guide rods 2331 on both sides of the sleeve plate 233. Thus, the suction force generated by the translation and extension of the corrugated pipe 234 will suck the gas in the dryer 1 through the cylindrical groove and the rectangular filter pipe 235. During one reciprocation of the corrugated pipe 234, the gas will exert a force on the rectangular groove plate 237 in the rectangular filter pipe 235. And the cross installation of the two groups of rectangular groove plates 237 will make the gas repeatedly contact the surface of the rectangular groove plates 237, so that the gas contacting the two groups of rectangular groove plates 237 can specifically present a passive flow deflection movement trajectory. Thus, it receives the heat emitted by the heating plate 238 in the rectangular groove plates 237, causing the temperature of the gas to rise. Then, when it is squeezed back into the dryer 1, it will have an additional heating and drying effect on the limestone in the dryer 1. At the same time, the gas ejected with impact will enter the trough plate box 242 through the sieve plate 25; At the same time, the passive sleeve plate 233 will also drive the fixedly installed U-shaped plate 240 to translate synchronously. In this way, the U-shaped plate 240 can drive the arc-shaped plate 241 to contact and squeeze the two elastic telescopic rods 244, causing them to drive the rubber plate 245 to move downward synchronously, generating a squeezing force in the trough plate box 242 and the U-shaped liquid plate 246, and squeezing the water body entering the U-shaped liquid plate 246 through the liquid hopper 243 to be ejected from multiple atomizing nozzles 247. Thus, the dust is dusted, which is convenient for collection and subsequent cleaning. Subsequently, the aggregate drawer 248 in the trough plate box 242 can be directly pulled out to perform overall cleaning treatment on it.

10. An environmentally friendly drying method, applied to the environmentally friendly drying device of claim 9, characterized in that: The specific operation method is as follows: S1. Limestone can be put into the dryer (1) by opening the door (11), and then the forward and reverse rotating motor (22) on the frame (21) is started to drive the rotating rod (23) and the mesh plate (24) fixed on the rotating rod (23) to rotate synchronously, so that the passively rotating mesh plate (24) will scoop the limestone in the dryer (1), and the limestone will fall naturally during the rotation process; S2. The rotation of the rotating rod (23) will also synchronously drive the meshing assembly (27) to rotate mutually. When the screw rod (231) rotates passively in the positive direction, it will first drive the sleeve plate (233) and then indirectly drive the bellows (234) to translate and extend. The suction force generated by the translation and extension of the bellows (234) will suck the gas in the dryer (1) through the cylindrical groove and the rectangular filter tube (235). During the reciprocating process of the bellows (234), the gas will forcefully move the rectangular groove plate (237) in the rectangular filter tube (235). The cross-installation of the two sets of rectangular groove plates (237) will cause the gas to repeatedly contact the surface of the rectangular groove plates (237), thereby receiving the heat emitted by the heating plate (238) in the rectangular groove plates (237), causing the gas temperature to rise. S3. The passive sleeve plate (233) also drives the fixed U-shaped plate (240) to move synchronously, so that the U-shaped plate (240) can drive the arc angle plate (241) to contact and squeeze the two elastic telescopic rods (244), so that the two elastic telescopic rods (244) drive the rubber plate (245) to move downward synchronously, thereby generating a squeezing force in the groove plate box (242) and the U-shaped liquid plate (246), squeezing the water that enters the U-shaped liquid plate (246) through the liquid bucket (243) and spraying it out from the multiple atomizing nozzles (247), thereby reducing dust.
