Description

Technical Field

[0001] The invention relates to the technical field of sludge treatment, in particular to a sludge chemical conditioning device. Background Art

[0002] Sludge concentration can generally only reduce its moisture content to about 85%. To further reduce the moisture content and reduce the volume, it is necessary to separate the bound water in the sludge, that is, to weaken the adhesion of this part of water to solid particles, causing the particles to become unstable and grow. The current common practice is to add flocculants such as ferric chloride and lime to the sludge, which can effectively eliminate viruses and reduce the moisture content to about 60%. The key to the sludge lime treatment process is the effective mixing of sludge and lime. The more primitive treatment device is to add lime powder to the worm conveyor. The material mainly only undergoes the pushing process, so the mixing is not uniform. In addition, as the sludge is dried, the moisture content of the sludge decreases, and it is more difficult to stir and mix it through traditional equipment.

[0003] The invention patent with publication number CN115028342B discloses a sludge chemical conditioning device, which utilizes the plasticity of the sludge, adopts the method of spreading a thin layer of sludge and then lime, and adding a layer of sludge to cover, so as to achieve full and uniform contact between the sludge and the lime. Since the device utilizes the plasticity of the sludge, it means that the fluidity of the sludge is relatively poor at this time, so it can be stably stacked on the bottom plate. In this case, the sludge has poor fluidity, and the output stability and uniformity of the extruder will be affected, and the absorption reaction efficiency in the reaction process with lime will also be reduced. While spreading the sludge, the device also uses a scraper to synchronously scrape off the second layer of sludge as a whole. At this time, since the position of the scraper is close to the position of the second layer of sludge output port, the second layer of sludge is scraped and collected as a whole just after it is spread, while the first layer of sludge can be laid on the lime layer. After that, it takes a relatively long time to react. Since the lime will first react with the lower layer of sludge to dehydrate, and the upper layer of sludge is in the later stage of laying, it is inevitable that the water content of the upper layer of sludge is quite different from that of the lower layer, and the reaction time of the upper layer of sludge is also shorter and delayed than that of the lower layer. After being pushed and thrown out by the scraper, the sludge is scattered all around. The original alternating three-layer structure will fly in the process of throwing out due to the difference in texture of the three layers and the effect of centrifugal force, so that the final distribution state of the sludge and lime cannot be evenly and stably mixed, and the treatment efficiency of the upper and lower layers of sludge is quite different. In the subsequent transportation process, it is still necessary to fully mix and stir to ensure that the overall output sludge composition is uniform. At the same time, the use scenario of the device is relatively limited. If the sludge is too dry, it is difficult to output it evenly from the extruder head, and if it is too thin, it is difficult to lay and form on the bottom plate. It is not convenient and efficient to use. Summary of the invention

[0018] See also Figure 1-Figure 11 A sludge chemical conditioning device shown in the figure includes a body 1, a conveying mechanism 5, a conditioning mechanism 9 and a driving mechanism 13.

At the same time, the stirring speed will decrease with the decrease of the water content of the sludge. The driving mechanism 13 is installed on the machine body 1, and is used to drive the rotating ring 6 to rotate while discharging the sludge in the discharge hopper 4 after the conditioning is completed.

The side of the fixed column 14 is provided with an arc groove 19 and a convex groove 20 that can be slidably connected to the outer wall of the guide block 18. The two ends of the arc groove 19 are connected to the two ends of the convex groove 20, and the middle part of the convex groove 20 is convex toward the side of the discharge hopper 4.

[0022] The tempering mechanism 9 also includes a bevel gear 21 fixedly mounted on the rotating frame 11, the fixed tube 16 passes through the bevel gear 21 and slides in contact with the inner wall of the bevel gear 21, a plurality of groups of nozzles 22 are slidably connected to the side of the stirring tube 12 in the horizontal direction, a plurality of groups of side holes 23 connected to the stirring tube 12 are provided on the side of the nozzle 22, one end of the nozzle 22 is fixedly connected to a tension spring 24 fixedly connected to the inner wall of the stirring tube 12, and the pneumatic powder pump 10 is provided with a conveying member 25 for conveying lime powder into the stirring tube 12 by pneumatic force.

[0023] The conveying member 25 includes a connecting pipe 26 connected to the output end of the pneumatic powder feeding pump 10, one end of the connecting pipe 26 is connected to the conveying pipe 27, the outer wall of the conveying pipe 27 is rotatably connected to the rotating pipe 28, and a plurality of groups of first pipes 29 that can be connected to the conveying pipe 27 are evenly and fixedly connected to the rotating pipe 28. The first pipes 29 pass through the guide block 18 and are movably connected to the inner wall of the fixed pipe 16. The connecting pipe 26 passes through the fixed column 14 and is fixedly connected to the fixed column 14. A second pipe 30 for connecting the top end of the fixed pipe 16 and the side of the bottom end of the stirring pipe 12 is opened in the pushing plate 8.

[0024] The tempering mechanism 9 also includes a first bevel gear ring 31, a second bevel gear ring 32 and an arc ring 33 fixedly mounted on the outer wall of the fixed column 14. The first bevel gear ring 31, the second bevel gear ring 32 and the arc ring 33 are connected to each other at both ends to form a circular ring shape. The first bevel gear ring 31 is located on the upper side of the second bevel gear ring 32 and the arc ring 33, and the arc ring 33 is located on the side close to the discharge hopper 4. The first bevel gear ring 31 and the second bevel gear ring 32 can both engage with the bevel gear 21, and the tooth density of the first bevel gear ring 31 is greater than the tooth density of the second bevel gear ring 32.

[0025] In this embodiment, the sludge to be tempered is input through the feed hopper 3, and the driving mechanism 13 drives the rotating ring 6 to rotate slowly, so that the conveying cylinder 7 rotates with the connecting ring 15. After the conveying cylinder 7 rotates to a position connected with the bottom end of the feed hopper 3, the sludge can be input into the conveying cylinder 7 for storage and tempering. The conveying cylinder 7 drives the push plate 8, the fixed tube 16, the guide block 18, the first pipeline 29 and the rotating tube 28 to rotate around the outer wall of the conveying tube 27 as a whole. The lime powder in the storage box 42 is continuously pumped into the connecting tube 26 and input into the conveying tube 27 through the wind power powder pump 10. The conveying tube 27 has only one group of openings facing the upper side. The multiple groups of first pipelines 29 on the rotating tube 28 can be connected with the openings of the conveying tube 27 one by one during the rotation process to ensure the stability of airflow transportation.

[0026] When the first pipe 29 is connected with the conveying pipe 27, the first pipe 29 and the fixed pipe 16 are both in the upper area. At this time, the guide block 18 at the bottom of the fixed pipe 16 slides into the arc groove 19, so that one end of the fixed pipe 16 is close to the rotating pipe 28, and the fixed pipe 16 pulls the push plate 8 down to a position close to the rotating frame 11, so that the second pipe 30 is connected with the side opening of the stirring pipe 12, so that the lime powder in the conveying pipe 27 can be input into the nozzle 22 through the first pipe 29, the fixed pipe 16, the second pipe 30, and the stirring pipe 12, and the nozzle 22 is pushed to slide outward until the lime powder is sprayed into the sludge in the conveying cylinder 7 through the side hole 23, and the lime and the sludge are fully mixed and tempered. As the first pipe 29 rotates, the connection with the conveying pipe 27 is released, and the input of lime powder can be stopped. By controlling the power of the pneumatic powder pump 10, the input amount of lime powder can be controlled.

[0027] When the conveying cylinder 7 is rotating, it drives the bevel gear 21 at the bottom to revolve together with the connecting ring 15, and at the same time, the bevel gear 21 will roll on the first bevel gear ring 31 and the second bevel gear ring 32, thereby driving the rotating frame 11 and the stirring tube 12 to rotate around the first pipe 29. At this time, the function of synchronous stirring of the sludge in the tempering process can be realized. During the rotation of the stirring tube 12, the push plate 8 will be driven to rotate together. This process does not affect the guide block 18 driving the push plate 8 to slide in the conveying cylinder 7, and the structural connection is ingenious and stable.

[0028] It is worth noting that: when the conveying cylinder 7 rotates to the upper area, it is in the tempering stage, the bevel gear 21 is meshed with the first bevel gear ring 31, and the rotation speed of the bevel gear 21 is relatively fast. At this time, the sludge water content is relatively high. At the same time, the process of the sprinkler 22 spraying lime powder requires rapid stirring for mixing reaction. At this time, the push plate 8 is at the bottom position and will not affect the sliding of the sprinkler 22. Afterwards, as the conveying cylinder 7 rotates, the bevel gear 21 gradually meshes with the second bevel gear ring 32. At this time, the water content of the sludge decreases and the viscosity increases. If high-speed stirring continues, it will cause great damage to the stirring tube 12. At this time, it means that it has approached the qualified tempering state and no high-speed stirring is required. At this time, the guide block 18 is in the arc groove 19, and the push plate 8 is still at the bottom position.

[0029] Afterwards, the conveying cylinder 7 gradually rotates toward the discharge hopper 4. At this time, the guide block 18 gradually slides from the arc groove 19 to the convex groove 20, pushing the fixed tube 16 and the push plate 8 to slide in the conveying cylinder 7, pushing the relatively dry sludge out of the conveying cylinder 7 and falling into the discharge hopper 4 for storage and collection. At this time, the bevel gear 21 is on the side close to the arc ring 33, and the arc ring 33 will not drive the bevel gear 21 to rotate. At this time, the push plate 8 only needs to slide and push out the operation. Then the conveying cylinder 7 rotates again to the position connected to the feed hopper 3 to input sludge to perform continuous conditioning operation, thereby improving the conditioning efficiency. In order to adapt to the stirring and conditioning of sludge with different moisture contents, the size of the conveying cylinder 7 does not need to be set too large. Continuous rotation and transportation can ensure continuous conditioning operation, and at the same time, the stirring efficiency of the internal stirring tube 12 can be increased, thereby extending the overall service life of the equipment.

[0030] It should be noted that: when the push plate 8 slides in the conveying cylinder 7, the second pipe 30 is not connected to the stirring tube 12 at this time, and the nozzle 22 will be pulled into the stirring tube 12 under the action of the tension spring 24. At this time, the nozzle 22 will not hinder the movement of the push plate 8. At the same time, the push plate 8 can fully push out the sludge adhered to the inner wall of the conveying cylinder 7 and the outer wall of the stirring tube 12 during the pushing process, and only a small amount of sludge remains on the surface of the push plate 8, which greatly improves the efficiency of self-purification and facilitates the long-term and stable use of the equipment. In the process of the lime powder being ejected through the side hole 23, the stirring The tube 12 is in a state of high-speed rotation and stirring, so that the lime powder can be quickly input into various positions of the sludge and the stirring is completed directly. At this time, due to the continuous high-pressure airflow ejected from the side hole 23, the sludge will not flow into the nozzle 22 through the side hole 23. When the airflow stops ejecting, the tension spring 24 pulls back, and the economic department pulls the side hole 23 back into the stirring tube 12 to prevent the sludge from entering the stirring tube 12, effectively improving the overall mixing efficiency of the lime powder and the sludge, so that the sludge output through the discharge hopper 4 does not need to be subsequently mixed and stirred to obtain sludge with a relatively uniform overall texture. Example

[0031] See also Figure 2-Figure 5 The present embodiment further illustrates the first embodiment. The driving mechanism 13 shown in the figure includes a driving motor 34 fixedly mounted on the machine body 1. The driving motor 34 is preferably of model Y80M1-2. The output end of the driving motor 34 is coaxially fixedly connected with a driving gear 35. The outer wall of the rotating ring 6 is fixedly connected with an outer gear ring 36 meshing with the driving gear 35. The driving gear 35 is provided with an output member 37 for outputting the sludge in the discharge hopper 4 in a linked manner during the rotation of the driving gear 35.

[0032] The output member 37 includes a worm 38 coaxially fixedly mounted on the driving gear 35, an output shaft 39 rotatably connected inside the discharge hopper 4, an outer wall of the output shaft 39 is fixedly connected to a conveying screw 40 that slides in contact with the inner wall of the bottom end of the discharge hopper 4, and one end of the output shaft 39 is coaxially fixedly connected to a worm wheel 41 that meshes with the worm 38.

[0033] In this embodiment, the driving motor 34 drives the driving gear 35 to rotate, and the driving gear 35 drives the outer gear ring 36 to make the rotating ring 6 and the conveying cylinder 7 rotate as a whole, and the driving gear 35 drives the worm 38 to rotate, so that the worm wheel 41 and the output shaft 39 and the conveying screw 40 rotate synchronously, and the conveying screw 40 outputs the sludge in the discharge hopper 4. At the same time, the output torque is increased and the output power is improved by setting the worm 38 and the worm wheel 41. At the same time, the sludge output rate and the sludge tempering rate are synchronously regulated. When the speed of the driving motor 34 increases, the speed of the conveying cylinder 7 increases, and the sludge conveying and tempering rate through the conveying cylinder 7 increases. At the same time, the speed of the conveying screw 40 increases, and the sludge output efficiency also increases synchronously. On the contrary, when the speed of the driving motor 34 decreases, the tempering and output rates decrease, and the overall adjustment is more convenient and efficient.
