Description

Technical Field

[0001] This utility model belongs to the field of environmental protection and sludge treatment technology, specifically a circulating micro-vortex high-temperature oxidation sludge automatic turning and mixing treatment chamber. Background Technology

[0002] With the acceleration of industrialization and urbanization, the production of sewage sludge has increased dramatically. Sludge not only contains large amounts of organic pollutants and pathogens, but may also contain harmful substances such as heavy metals. If not properly treated, these harmful substances can cause serious pollution to soil, water bodies, and the atmosphere, thereby threatening ecological balance and human health. Therefore, developing efficient and environmentally friendly sludge treatment technologies has become a critical issue that urgently needs to be addressed in the environmental field. Currently, common sludge treatment methods include landfill, incineration, and composting. However, these traditional methods have many drawbacks: landfill, while simple to operate, occupies a large amount of land resources, and harmful substances in the sludge may seep into groundwater over time, causing secondary pollution; incineration, while achieving sludge reduction and harmlessness, is energy-intensive and easily produces highly toxic substances such as dioxins during combustion, posing a significant threat to the environment and human health; composting can convert sludge into organic fertilizer, but its processing cycle is long, requires a large area, its treatment effect is significantly affected by environmental factors, and the product quality is unstable, making it difficult to meet actual needs.

[0003] In sludge treatment, a thorough oxidation reaction is crucial for achieving the harmlessness and stabilization of sludge. However, traditional sludge treatment equipment often fails to ensure sufficient contact between sludge and oxygen, leading to incomplete oxidation and affecting treatment efficiency. Furthermore, sludge tends to accumulate and clump during treatment, further reducing efficiency and effectiveness. Moreover, existing mixing equipment has a low degree of automation, typically requiring extensive manual operation, which is not only labor-intensive but also results in uneven mixing, failing to meet the demands of large-scale, high-efficiency sludge treatment. Therefore, there is an urgent need for a treatment device that can achieve efficient sludge oxidation, automatic mixing, and prevent accumulation and clumping, to overcome the shortcomings of existing technologies and improve the efficiency and effectiveness of sludge treatment. Utility Model Content

[0004] To address the technical problems mentioned in the background art, such as insufficient oxidation reaction, uneven mixing effect, and low degree of automation in sludge treatment, a circulating micro-vortex high-temperature oxidation sludge automatic mixing chamber is provided to achieve efficient sludge oxidation and uniform mixing.

[0005] To achieve the above objectives, the specific technical solution of the automatic turning and mixing chamber for circulating micro-vortex high-temperature oxidation sludge of this utility model is as follows:

[0006] An automatic turning and mixing chamber for circulating micro-vortex high-temperature oxidation sludge includes a chamber body and a turning and mixing mechanism. The turning and mixing mechanism is located inside the chamber body. The top of the chamber body has a feed inlet and the bottom has a discharge outlet. Multiple guide plates are provided on the inner wall of the chamber body. A micro-vortex generator is connected to the end of the guide plate away from the inner wall of the chamber body. The turning and mixing mechanism and the micro-vortex generator are connected through a drive shaft. A drive motor is provided on the outside of the chamber body. The drive motor is connected to the drive shaft through a gear set so that the turning and mixing mechanism and the micro-vortex generator operate synchronously.

[0007] Furthermore, the mixing mechanism includes a main shaft and multiple mixing blades. The main shaft rotates inside the chamber, and the multiple mixing blades are welded to the main shaft at intervals. The mixing blades are distributed in a spiral shape to make the sludge circulate within the chamber.

[0008] Furthermore, multiple reinforcing ribs are welded at intervals on the main shaft, and the ends of the multiple reinforcing ribs away from the main shaft are all welded to the stirring blades to enhance the structural strength of the stirring blades.

[0009] Furthermore, the micro vortex generator includes multiple vortex vanes, which are arc-shaped and arranged in a ring along the inner wall of the chamber. The end of the vortex vane away from the inner wall of the chamber is connected to a guide groove so that the sludge forms a micro vortex effect inside the chamber.

[0010] Furthermore, the guide plate is provided with multiple vent holes, and an oxygen nozzle is connected to the end of the vent hole away from the guide plate. The oxygen nozzle is connected to an external oxygen supply device through an oxygen supply pipe to achieve full contact between the sludge and oxygen.

[0011] Furthermore, an insulation layer is installed on the outside of the cabin, and the insulation layer is filled with high-temperature resistant materials to reduce heat loss and maintain a high-temperature environment inside the cabin.

[0012] Furthermore, the transmission shaft includes a first transmission shaft and a second transmission shaft. The first transmission shaft is connected to the stirring mechanism, and the second transmission shaft is connected to the micro-vortex generator. The second transmission shaft is sleeved and rotates on the first transmission shaft. The second bevel gear is located at the output end of the drive motor and is used to drive the first bevel gear and the third bevel gear to rotate. The first bevel gear is located on the second transmission shaft and meshes with the second bevel gear. The third bevel gear is located on the first transmission shaft and meshes with the second bevel gear. The first bevel gear is located below the third bevel gear. The first bevel gear and the third bevel gear rotate in opposite directions to achieve synchronous transmission and efficient stirring.

[0013] Furthermore, multiple stirring blades are inclinedly arranged on the main shaft, and each stirring blade is equipped with a scraper at the end away from the main shaft. The scraper works in conjunction with the micro vortex generator to improve the stirring efficiency.

[0014] Furthermore, the swirl vanes are wavy to create multi-directional micro-swirling motions of the sludge within the chamber.

[0015] Furthermore, the bottom of the chamber is cone-shaped to allow the treated sludge to be discharged quickly.

[0016] The automatic turning and mixing chamber for circulating micro-vortex high-temperature oxidation sludge of this invention has the following advantages:

[0017] By incorporating a stirring mechanism and a micro-vortex generator within the chamber, the sludge achieves circulation and a micro-vortex effect, ensuring full contact between the sludge and oxygen and improving the efficiency of the oxidation reaction. The spiral blade design of the stirring mechanism effectively prevents sludge accumulation and clumping, ensuring uniform mixing. The insulation layer on the outside of the chamber maintains a high-temperature environment, promoting the harmless treatment of sludge. Simultaneously, the high degree of automation reduces manual operation and significantly improves the efficiency and effectiveness of sludge treatment. Attached Figure Description

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. The utility model will be further described in detail below with reference to the accompanying drawings.

[0025] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; 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; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0026] This utility model provides an automatic turning and mixing chamber for circulating micro-vortex high-temperature oxidation sludge, the overall structure of which is as follows: Figure 1 As shown, the device includes a chamber 1, a stirring mechanism, a micro-vortex generator 5, and related auxiliary components. The chamber 1 is the core component of the entire device, with a feed inlet 2 at the top and a discharge outlet 3 at the bottom. Multiple guide plates 4 are installed on the inner wall of the chamber 1, and the micro-vortex generator 5 is connected to the end of each guide plate 4 away from the inner wall of the chamber. The stirring mechanism and the micro-vortex generator 5 are connected via a drive shaft 6. A drive motor 7 is located on the outer side of the chamber 1, and the drive motor 7 is connected to the drive shaft 6 via a gear set to achieve synchronous operation of the stirring mechanism and the micro-vortex generator 5. The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0027] First, the stirring mechanism is an important component of this utility model, and its specific structure is as follows: Figure 2As shown, the mixing mechanism includes a main shaft 8 and multiple mixing blades 9. The main shaft 8 rotates within the chamber, and the multiple mixing blades 9 are welded to the main shaft 8 at intervals and arranged in a spiral pattern. This spiral distribution design allows the sludge to circulate within the chamber 1, thereby preventing sludge accumulation and clumping, and ensuring uniform mixing. Furthermore, multiple reinforcing ribs 10 are welded to the main shaft 8 at intervals. The ends of the reinforcing ribs 10 away from the main shaft 8 are all welded to the mixing blades 9 to enhance the structural strength of the mixing blades 9, making them less prone to deformation or damage during long-term operation. To further improve the mixing effect, the multiple mixing blades 9 are inclinedly arranged on the main shaft 8, and each mixing blade 9 has a scraper 18 at the end away from the main shaft 8. The scraper 18 cooperates with the micro-vortex generator 5. This design not only improves the mixing efficiency but also effectively reduces the amount of manual cleaning work.

[0028] Secondly, the micro-vortex generator 5 is another key component of this invention, and its specific structure is as follows: Figure 3 As shown, the micro-vortex generator 5 includes multiple vortex vanes 11, which are arc-shaped and arranged in a ring along the inner wall of the chamber 1. The design of the vortex vanes 11 creates a micro-vortex effect in the sludge within the chamber 1, thereby promoting sufficient contact between the sludge and oxygen and improving the efficiency of the oxidation reaction. To further optimize the micro-vortex effect, the vortex vanes 11 are designed in a wave shape. This design enables the sludge to form multi-directional micro-vortex motion within the chamber 1, thereby further improving the mixing uniformity and oxidation effect of the sludge. In addition, the guide plate 4 is provided with multiple vent holes 12. The end of the vent hole 12 away from the guide plate 4 is connected to an oxygen nozzle 13, which is connected to an external oxygen supply device through an oxygen supply pipe. This design can uniformly deliver oxygen into the interior of the chamber 1, ensuring sufficient contact between the sludge and oxygen, thereby improving the efficiency of the oxidation reaction.

[0029] Furthermore, an insulation layer 14 is provided on the outside of the chamber 1, filled with high-temperature resistant material to reduce heat loss and maintain a high-temperature environment inside the chamber 1. A high-temperature environment is crucial for the harmless treatment of sludge, as it accelerates the decomposition and oxidation of organic matter in the sludge. The design of the insulation layer 14 not only effectively reduces heat loss but also lowers energy consumption, thereby improving the overall operating efficiency of the device.

[0030] The drive shaft 6 is a key component connecting the stirring mechanism and the micro-vortex generator 5, and its specific structure is as follows: Figure 1As shown. The drive shaft 6 includes a first drive shaft 15 and a second drive shaft 16. The first drive shaft 15 is connected to the stirring mechanism, and the second drive shaft 16 is connected to the micro-vortex generator 5. The second drive shaft 16 is sleeved and rotates on the first drive shaft 15. A second bevel gear 22 is located at the output end of the drive motor 7 and is used to drive a first bevel gear 21 and a third bevel gear 23 to rotate. The first bevel gear 21 is located on the second drive shaft 16 and meshes with the second bevel gear 22. The third bevel gear 23 is located on the first drive shaft 15 and meshes with the second bevel gear 22. The bevel gear 21 is located below the third bevel gear 23. The first bevel gear 21 and the third bevel gear 23 rotate in opposite directions to achieve synchronous transmission and efficient stirring. This design ensures that the stirring mechanism and the micro-vortex generator 5 remain synchronized during operation, thereby improving the operational stability and reliability of the entire device. The drive motor 7 is connected to the drive shaft 6 through a gear set 20. The operation of the drive motor 7 can drive the stirring mechanism and the micro-vortex generator 5 to operate synchronously, thereby achieving efficient stirring and micro-vortex effect of the sludge.

[0031] In practical applications, the working process of the automatic turning and mixing chamber for circulating micro-vortex high-temperature oxidation of sludge of this utility model is as follows: First, sludge enters the chamber 1 through the feed inlet 2. After the drive motor 7 starts, it drives the transmission shaft 6 to rotate through the gear set. The rotation of the transmission shaft 6 further drives the turning mechanism and the micro-vortex generator 5 to operate synchronously. The main shaft 8 and turning blades 9 in the turning mechanism start to rotate. The spiral design of the turning blades 9 makes the sludge form a circulating flow in the chamber 1, thereby avoiding sludge accumulation and clumping. At the same time, the vortex vanes 11 in the micro-vortex generator 5 start to work, making the sludge form a micro-vortex effect in the chamber 1, thereby promoting full contact between the sludge and oxygen. The vent holes 12 and oxygen nozzles 13 on the guide plate 4 deliver oxygen evenly into the chamber 1, further improving the contact area between the sludge and oxygen and the efficiency of the oxidation reaction. The heat insulation layer 14 on the outside of the chamber 1 can maintain the high-temperature environment inside the chamber 1, promoting the harmless treatment of sludge. After treatment, the sludge is discharged through the discharge port 3 at the bottom of the chamber 1, completing the entire treatment process.

[0032] In summary, the automatic sludge-turning and mixing chamber for circulating micro-vortex high-temperature oxidation of this invention achieves sludge circulation and micro-vortex effect within the chamber 1 through the synergistic action of the turning mechanism and the micro-vortex generator 5. This ensures sufficient contact between the sludge and oxygen, improving the efficiency of the oxidation reaction. The spiral blade design of the turning mechanism effectively prevents sludge accumulation and clumping, ensuring uniform mixing. The insulation layer 14 on the outside of the chamber 1 maintains a high-temperature environment, promoting the harmless treatment of sludge. Furthermore, the high degree of automation reduces manual operation and significantly improves the efficiency and effectiveness of sludge treatment.
