Abstract
Description
Technical Field
[0001] This utility model relates to the field of sludge treatment technology, and in particular to a sludge drying machine with deodorization and purification functions. Background Technology
[0002] With China's water consumption increasing, the volume of sewage treatment is also growing. Sludge, as a byproduct of sewage treatment, is characterized by its large volume, high water content, and strong odor. Sludge has a complex composition and contains heavy metals, pathogenic microorganisms, and organic matter, which can easily cause pollution. In recent years, the workload of sludge treatment has increased, and drying sludge is an effective means to achieve its harmlessness and volume reduction.
[0003] Currently, various drying methods are used to effectively dry sludge. However, the odor emitted by the sludge is difficult to eliminate, requiring a series of deodorization and purification processes. Furthermore, during the drying process, the stickiness of the sludge causes it to adhere to the inside of the dryer, making it difficult to break up the adhering sludge during operation, thus affecting work efficiency. Therefore, it is necessary to address the issues of sludge adhering to the inside of the dryer and to effectively deodorize and purify it. Utility Model Content
[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the existing technology and provide a sludge drying machine with deodorization and purification functions.
[0005] This utility model is achieved through the following technical solution:
[0006] A sludge drying machine with deodorization and purification functions includes a drying cylinder and a deodorization box. A first motor is provided at one end of the drying cylinder, and a second motor is provided at the other side of the drying cylinder. A sludge inlet is provided on one side of the top of the drying cylinder, and a sludge outlet is provided on one side of the bottom of the drying cylinder. A saturated steam inlet is provided at the bottom of one end of the drying cylinder, and a condensate outlet is provided at the bottom of the other end of the drying cylinder. An air pipe is provided at the center of the top of the drying cylinder, and a fan is provided on the outside of the air pipe. An exhaust port is provided at the top of the deodorization box.
[0007] As can be seen, in the above technical solution, when the sludge drying drum is drying, the deodorization box will take the gas emitted by the sludge in the drying drum and the saturated steam into the deodorization box through the fan for deodorization and purification before discharge, so that the drying and deodorization work are carried out at the same time, which effectively reduces the working time and improves the working efficiency.
[0008] Optionally, in one possible implementation, a rotating shaft is located at the center of the drying cylinder, with conveying blades on the outer side of one end of the shaft and crushing blades on the outer side of the other end. It can be seen that in the above technical solution, when the sludge enters the drying box, it is conveyed by the conveying blades, and after final drying, the sludge is crushed by the crushing blades. This effectively prevents the dried sludge from hardening and clogging the outlet, thus improving its working efficiency.
[0009] Optionally, in one possible implementation, the deodorization box is equipped with a filter tank inside, with absorbent cotton at the bottom of the filter tank, an activated carbon adsorption layer at the bottom of the absorbent cotton, and a chemical agent layer at the bottom of the activated carbon adsorption layer. It can be seen that in the above technical solution, after the odor and vapor enter the deodorization box, some dried small particles of sludge will be drawn into the air pipe by the fan, so they will first be filtered through the filter tank. Since the odor and vapor contain moisture, the absorbent cotton will adsorb the moisture. Then, the porous structure of the activated carbon adsorption layer will adsorb organic pollutants and some inorganic pollutants in the odor, achieving the purpose of deodorization. Finally, the chemical agent will react with the odor to neutralize it and reduce the odor. Through this series of deodorization methods, the odor generated by the sludge is effectively removed.
[0010] Optionally, in one possible implementation, the two sides of the filter tank are welded to the inner wall of the deodorization box, and a barrier layer is provided on the outer side of the chemical agent layer. It can be seen that in the above technical solution, since the fan draws gas into the air pipe, it will also introduce some dried small granular sludge. Therefore, the filter tank needs to firmly support the granular sludge to improve its load-bearing capacity. The chemical agents have certain hazards and corrosiveness, so a barrier layer is needed to prevent leakage.
[0011] Optionally, in one possible implementation, the air pipe extends into the interior of the drying cylinder, and the other end of the air pipe extends into the interior of the deodorizing box. The drying cylinder and the deodorizing box are connected by the air pipe, which is U-shaped inside the deodorizing box. It can be seen that in the above technical solution, during the drying process, the odorous gas is transported to the deodorizing box through the air pipe. The air pipe is U-shaped inside the deodorizing box, and the air pipe allows the odorous gas to pass through the deodorizing box twice. This allows the moisture from the chemical agent layer to be absorbed by the absorbent cotton after passing through, and then discharged through the exhaust port. This two-stage deodorization process effectively achieves deep deodorization and purification of the odorous gas.
[0012] Optionally, in one possible implementation, the inner wall of the drying cylinder is provided with an insulation layer, and a chain is provided on the outer side of the conveying blades. It can be seen that in the above technical solution, the insulation layer can seal and insulate the interior, making the drying process more efficient. The chain on the conveying blades can prevent sludge from sticking to the drying cylinder and can better break up the dried sludge.
[0013] Optionally, in one possible implementation, a reversing shaft is provided inside the rotating shaft. The conveying blades are connected to the reversing shaft every other conveying blade. The rotating shaft is connected to a first motor, and the reversing shaft is connected to a second motor. The crushing blades are connected to the rotating shaft, and adjacent crushing blades are connected to the reversing shaft. It can be seen that in the above technical solution, the internal conveying blades can be rotated in two directions by two motors, allowing for better crushing of the dried sludge. After crushing, the second motor is turned off to transport the sludge to the outlet, where it is further crushed by the crushing blades in both directions, effectively improving the transport and crushing of the sludge inside the drying drum.
[0014] The beneficial effects of this utility model are:
[0015] In this utility model, when the sludge drying cylinder is drying, the deodorization box will take the gas emitted by the sludge in the drying cylinder and the saturated steam together into the deodorization box through the fan for deodorization and purification before discharge. This allows the drying and deodorization work to be carried out at the same time, effectively reducing working time and improving work efficiency.
[0016] At the same time, through the U-shaped air tube and deodorization box, the odor can be deodorized twice in reverse, effectively deodorizing and purifying the odor.
[0017] In addition, the chain on the conveyor blades prevents sludge from sticking to the drying drum and allows for better crushing of the dried sludge. Two motors rotate the internal conveyor blades in two directions, further crushing the dried sludge. After crushing, the second motor is turned off to transport the sludge to the outlet, where it is further crushed by the crushing blades in two directions. This effectively improves the transport and crushing of the sludge inside the drying drum. Attached Figure Description

Therefore, they should not be construed as limitations on the utility model.
[0028] Example 1: As Figure 1-6As shown, this embodiment provides a sludge dryer with deodorization and purification functions, including a drying cylinder 1 and a deodorization box 2. The inner wall of the drying cylinder 1 is provided with a heat insulation layer 101. The deodorization box 2 is provided with a filter tank 201. The bottom of the filter tank 201 is provided with absorbent cotton 202. The bottom of the absorbent cotton 202 is provided with an activated carbon adsorption layer 203. The bottom of the activated carbon adsorption layer 203 is provided with a chemical agent layer 204. The two sides of the filter tank 201 are welded to the inner wall of the deodorization box 2. The chemical agent layer 204... The outer side of the drying cylinder 1 is equipped with a barrier layer. A first motor 3 is located at one end of the drying cylinder 1, and a second motor 4 is located at the other end. A sludge inlet 5 is located on one side of the top of the drying cylinder 1, and a sludge outlet 6 is located on one side of the bottom of the drying cylinder 1. A saturated steam inlet 7 is located at the bottom of one end of the drying cylinder 1, and a condensate outlet 8 is located at the bottom of the other end. An air pipe 9 is located at the center of the top of the drying cylinder 1, extending into the interior of the drying cylinder 1. The other end of the air pipe 9 extends into the interior of the deodorization box 2. The sludge is connected to the deodorization box 2 via an air pipe 9, which is U-shaped inside the deodorization box 2. A fan 10 is installed on the outside of the air pipe 9, and an exhaust port 11 is installed on the top of the deodorization box 2. A rotating shaft 12 is located at the center of the interior of the drying cylinder 1. A conveying blade 13 is installed on the outside of one end of the rotating shaft 12, and a chain 1301 is installed on the outside of the conveying blade 13. A crushing blade 14 is installed on the outside of the other end of the rotating shaft 12. A reversing shaft is installed on the inside of the rotating shaft 12. The conveying blades 13 are connected to the reversing shaft every other conveying blade 13. The rotating shaft 12 is connected to the first motor 3, and the reversing shaft is connected to the second motor 4. The crushing blades 14 are connected to the rotating shaft 12, and adjacent crushing blades 14 are connected to the reversing shaft. The two motors can rotate the internal conveying blades 13 in two directions, so that the dried sludge can be better crushed. After crushing, the second motor 4 is turned off to transport it to the outlet, and then the crushing blades 14 in two directions are used for more thorough crushing, which effectively transports and crushes the sludge inside the drying cylinder 1.
[0029] As can be seen, in the above technical solution, when the sludge drying cylinder 1 is drying, the deodorization box 2 will take the gas emitted by the sludge in the drying cylinder 1 and the saturated steam together into the deodorization box 2 through the blower 10 for deodorization and purification before discharge, so that the drying work and the deodorization work are carried out at the same time, which effectively reduces the working time and improves the working efficiency.
[0030] Furthermore, after the odor and steam enter the deodorization box 2, some dried small particles of sludge will be drawn into the air pipe 9 by the fan 4. Therefore, the odor and steam will first be filtered through the filter tank 201. Since there is moisture in the odor and steam, the moisture will be adsorbed by the absorbent cotton 202. Then, the pore structure of the activated carbon adsorption layer 203 will adsorb the organic pollutants and some inorganic pollutants in the odor to achieve the purpose of deodorization. Then, the chemical agent layer 204 will react with the odor to neutralize it and reduce the odor. In this series of deodorization methods, the odor generated by the sludge will be effectively removed.
[0031] Operating Procedure: During the drying process, the sludge drying cylinder 1, along with saturated steam, draws the gas emitted from the sludge in the drying cylinder 1 into the deodorization box 2 via the blower 10 for deodorization and purification before being discharged. This allows the drying and deodorization processes to proceed simultaneously. Since the blower 4 draws gas into the air pipe 9, some small dried sludge particles are also drawn in. Therefore, the filter tank 201 needs to firmly support these particles to improve its load-bearing capacity. Chemical agents are hazardous and corrosive, so a barrier layer is required to prevent leakage. During the drying process, the odorous gas is transported to the deodorization box 2 via the air pipe 9, which is U-shaped within the deodorization box 2. The air pipe 9 allows the odorous gas to pass through the deodorization box 2 twice. After the chemical agent layer 204 passes through, the moisture from the chemical agent is absorbed by the absorbent cotton 202, and then discharged through the exhaust port 11. This two-stage deodorization process effectively achieves deep deodorization and purification of the odorous gas.
[0032] Example 2: As Figure 1-6As shown, this embodiment provides a sludge dryer with deodorization and purification functions, including a drying cylinder 1 and a deodorization box 2. The inner wall of the drying cylinder 1 is provided with a heat insulation layer 101. The deodorization box 2 is provided with a filter tank 201. The bottom of the filter tank 201 is provided with absorbent cotton 202. The bottom of the absorbent cotton 202 is provided with an activated carbon adsorption layer 203. The bottom of the activated carbon adsorption layer 203 is provided with a chemical agent layer 204. The two sides of the filter tank 201 are welded to the inner wall of the deodorization box 2. The chemical agent layer 204... The outer side of the drying cylinder 1 is equipped with a barrier layer. A first motor 3 is located at one end of the drying cylinder 1, and a second motor 4 is located at the other end. A sludge inlet 5 is located on one side of the top of the drying cylinder 1, and a sludge outlet 6 is located on one side of the bottom of the drying cylinder 1. A saturated steam inlet 7 is located at the bottom of one end of the drying cylinder 1, and a condensate outlet 8 is located at the bottom of the other end. An air pipe 9 is located at the center of the top of the drying cylinder 1, extending into the interior of the drying cylinder 1. The other end of the air pipe 9 extends into the interior of the deodorization box 2. The sludge is connected to the deodorization box 2 via an air pipe 9, which is U-shaped inside the deodorization box 2. A fan 10 is installed on the outside of the air pipe 9, and an exhaust port 11 is installed on the top of the deodorization box 2. A rotating shaft 12 is located at the center of the interior of the drying cylinder 1. A conveying blade 13 is installed on the outside of one end of the rotating shaft 12, and a chain 1301 is installed on the outside of the conveying blade 13. A crushing blade 14 is installed on the outside of the other end of the rotating shaft 12. A reversing shaft is installed on the inside of the rotating shaft 12. The conveying blades 13 are connected to the reversing shaft every other conveying blade 13. The rotating shaft 12 is connected to the first motor 3, and the reversing shaft is connected to the second motor 4. The crushing blades 14 are connected to the rotating shaft 12, and adjacent crushing blades 14 are connected to the reversing shaft. The two motors can rotate the internal conveying blades 13 in two directions, so that the dried sludge can be better crushed. After crushing, the second motor 4 is turned off to transport it to the outlet, and then the crushing blades 14 in two directions are used for more thorough crushing, which effectively transports and crushes the sludge inside the drying cylinder 1.
[0033] As can be seen, in the above technical solution, when the sludge drying cylinder 1 is drying, the deodorization box 2 will take the gas emitted by the sludge in the drying cylinder 1 and the saturated steam together into the deodorization box 2 through the blower 10 for deodorization and purification before discharge, so that the drying work and the deodorization work are carried out at the same time, which effectively reduces the working time and improves the working efficiency.
[0034] Operating Procedure: During the drying process, the sludge drying cylinder 1 draws the gas emitted from the sludge in the drying cylinder 1, along with saturated steam, into the deodorization box 2 via the blower 10 for deodorization and purification before discharge. This allows the drying and deodorization processes to occur simultaneously. Since the blower 4 draws gas into the air pipe 9, some small dried sludge particles are also drawn in. Therefore, the filter tank 201 needs to firmly support these particles to improve load-bearing capacity. Because the chemical agents are potentially hazardous and corrosive, a barrier layer is required to prevent leakage. During the drying process, the odorous gas is transported to the deodorization box 2 via the air pipe 9, which is U-shaped within the deodorization box 2. The air pipe 9 allows the odorous gas to pass through the deodorization process twice. After passing through the chemical agent layer 204, the moisture from the chemical agents is absorbed by the absorbent cotton 202, and then discharged through the exhaust port 11. After two deodorization processes, the sludge can be more effectively deodorized and purified. When the sludge enters the drying chamber 1, it is conveyed by the conveyor blades 13. After final drying, the sludge is crushed by the crushing blades 14. This effectively prevents the dried sludge from hardening and clogging the outlet, thus increasing efficiency. The insulation layer 101 provides internal sealing and insulation, further enhancing the drying process. The chain 1301 on the conveyor blades 13 prevents the sludge from sticking to the drying chamber 1 and better crushes it. Two motors rotate the conveyor blades 13 in two directions, allowing for better crushing of the dried sludge. After crushing, the second motor 4 is turned off, and the sludge is transported to the outlet, where it is further crushed by the crushing blades 14 in two directions. This effectively improves the transport and crushing of the sludge inside the drying chamber 1. Obviously, the above embodiments are merely illustrative examples and not intended to limit the implementation. Those skilled in the art can make various variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, any obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
