Description

Technical Field

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

[0002] Sludge thickening generally can only reduce its moisture content to about 85%. To further reduce the moisture content and decrease the volume, the bound water in the sludge needs to be separated, that is, to weaken the adhesion of this part of water to solid particles and make the particles unstable and grow. The current common practice is to add flocculants such as ferric trichloride and lime to the sludge, which can effectively eliminate viruses and reduce the water content to about 60%. The key to the sludge lime treatment process is the effective mixing of sludge and lime. A relatively primitive treatment device is to add lime powder into a worm conveyor, and the material mainly only undergoes a pushing process, so the mixing is not uniform enough. And with the drying treatment of the sludge, the moisture content of the sludge decreases, and it is more difficult to carry out stirring and mixing through traditional equipment.

[0003] The invention patent with the publication number of CN115028342B discloses a sludge chemical conditioning device. Utilizing the plasticity of the sludge, it adopts the method of spreading a thin layer of sludge and then adding lime, and covering it with an additional layer of sludge, achieving sufficient and uniform contact between the sludge and lime. Since this device utilizes the plasticity of the sludge, it means that the fluidity of the sludge is relatively poor at this time, so that it can be stably stacked on the bottom plate. Then, with such poor sludge fluidity, the output stability and uniformity of the extrusion head will be affected, and the absorption reaction efficiency during the reaction with lime will also be reduced. And when spreading the sludge, this device also uses a scraper to synchronously scrape off the whole second layer of the spread sludge. At this time, because the position of the scraper is relatively close to the output port of the second layer of sludge, the second layer of sludge is scraped off and collected as a whole just after it is spread, while the first layer of sludge can react for a relatively long time after the lime layer is laid. Since lime will react with the lower-layer sludge for dehydration first, and the laying of the upper-layer sludge is in the later stage, this will inevitably lead to a large difference in the water content between the upper-layer sludge and the lower-layer sludge, and the reaction time of the upper-layer sludge is also shorter and delayed compared with the lower layer. After being pushed and thrown out by the scraper, the sludge scatters around. During the throwing process, the original three-layer structure of alternating stacking will fly apart due to the texture difference of the three layers and the action of centrifugal force, resulting in the final distribution state of the sludge and lime still unable to be evenly and stably mixed, and there is a large difference in the treatment efficiency between the upper and lower layers of sludge. During the subsequent conveying process, it still needs to be fully mixed and stirred to ensure the uniform composition of the overall output sludge. At the same time, the use scenario of this device is relatively limited. If the sludge is too dry, it is difficult to be evenly output from the extrusion head, and if it is too thin, it is difficult to be laid into a shape on the bottom plate, and the use is not convenient and efficient.

Embodiment

[0029] Please refer to Figures 1 - 11 , a sludge chemical conditioning device shown in the figure, including a body 1, a conveying mechanism 5, a conditioning mechanism 9 and a driving mechanism 13. A fixing ring 2 is fixedly connected to the body 1, and a feeding hopper 3 and a discharging hopper 4 are fixedly connected to the fixing ring 2. The conveying mechanism 5 includes a rotating ring 6 rotatably connected to the inner wall of the fixing ring 2. A plurality of groups of conveying cylinders 7 capable of communicating with the feeding hopper 3 and the discharging hopper 4 are uniformly fixedly connected to the rotating ring 6. A pushing plate 8 is slidably connected to the inner wall of the conveying cylinder 7, which is used to drive the conveying cylinder 7 to communicate with the feeding hopper 3 for sludge input during the rotation of the rotating ring 6, and to communicate with the discharging hopper 4 after conditioning, and push the sludge in the conveying cylinder 7 out through the pushing plate 8.

[0030] The conditioning mechanism 9 includes a pneumatic powder feeder 10 installed on the machine body 1. A storage tank 42 is fixedly connected to the machine body 1 and is communicated with the suction end of the pneumatic powder feeder 10. The storage tank 42 is used to store lime powder. The bottom of the conveying cylinder 7 is rotatably connected to a rotating frame 11. A plurality of stirring pipes 12 are evenly and fixedly connected to the rotating frame 11. During the process of the rotating ring 6 driving the conveying cylinder 7 to rotate, the rotating frame 11 is linked to drive the stirring pipes 12 to rotate and stir, and at a set position, the lime powder in the pneumatic powder feeder 10 is filled into the sludge in the conveying cylinder 7 through the side surface of the stirring pipes 12, realizing the function of uniform mixing and conditioning and stirring. At the same time, the stirring speed will decrease as the water content of the sludge decreases. The driving mechanism 13 is installed on the machine body 1 and is used to drive the rotating ring 6 to rotate while linking to discharge the conditioned sludge in the discharge hopper 4.

[0031] The conveying mechanism 5 includes a fixed column 14 fixedly installed on the machine body 1. A connecting ring 15 is sleeved outside the fixed column 14. The connecting ring 15 is fixedly connected to a plurality of conveying cylinders 7. The outer wall of the rotating frame 11 is rotatably connected to the inner wall of the connecting ring 15. A fixed pipe 16 is fixedly connected to the pushing plate 8. The fixed pipe 16 penetrates through the rotating frame 11. A moving member 17 is provided on the fixed column 14 for driving the fixed pipe 16 and the pushing plate 8 to move and adjust.

[0032] The moving member 17 includes a guiding block 18 fixedly installed at the bottom of the fixed pipe 16. An arc groove 19 and a convex groove 20 that can slide on the outer wall of the guiding block 18 are formed on the side surface of the fixed column 14. The two ends of the arc groove 19 are communicated with the two ends of the convex groove 20. The middle part of the convex groove 20 protrudes toward the discharge hopper 4 side.

[0033] The conditioning mechanism 9 further includes a bevel gear 21 fixedly installed on the rotating frame 11. The fixed pipe 16 penetrates through the bevel gear 21 and is in sliding fit with the inner wall of the bevel gear 21. A plurality of spray heads 22 are slidably connected to the side surface of the stirring pipe 12 in the horizontal direction. A plurality of side holes 23 communicated with the stirring pipe 12 are formed on the side surface of the spray heads 22. One end of the spray head 22 is fixedly connected to a tension spring 24 fixedly connected to the inner wall of the stirring pipe 12. A conveying member 25 is provided on the pneumatic powder feeder 10 for pneumatically conveying the lime powder into the stirring pipe 12.

[0034] The conveying member 25 includes a connecting pipe 26 communicated with the output end of the pneumatic powder feeder 10. One end of the connecting pipe 26 is communicated with a conveying pipe 27. The outer wall of the conveying pipe 27 is rotatably connected to a rotating pipe 28. A plurality of first pipes 29 that can be communicated with the conveying pipe 27 are evenly and fixedly connected to the rotating pipe 28. The first pipes 29 penetrate through the guiding block 18 and are movably sleeved on the inner wall of the fixed pipe 16. The connecting pipe 26 penetrates through the fixed column 14 and is fixedly connected to the fixed column 14. A second pipe 30 for communicating the top end of the fixed pipe 16 with the side surface of the bottom end of the stirring pipe 12 is formed in the pushing plate 8.

[0035] The quenching and tempering mechanism 9 further includes a first bevel gear ring 31, a second bevel gear ring 32 and an arc ring 33 fixedly installed on the outer wall of the fixed column 14. The two ends of the first bevel gear ring 31, the second bevel gear ring 32 and the arc ring 33 are connected to each other to form a circular ring. The first bevel gear ring 31 is located above the second bevel gear ring 32 and the arc ring 33. The arc ring 33 is located on the side close to the discharge hopper 4. Both the first bevel gear ring 31 and the second bevel gear ring 32 can mesh with the bevel gear 21, and the tooth density of the first bevel gear ring 31 is greater than that of the second bevel gear ring 32.

[0036] In this embodiment, the sludge to be quenched and 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 and the connecting ring 15 rotate together. After the conveying cylinder 7 rotates to the position communicated with the bottom end of the feed hopper 3, the sludge can be input into the conveying cylinder 7 for storage and quenching and tempering. The conveying cylinder 7 drives the push plate 8, the fixed pipe 16, the guide block 18, the first pipe 29 and the rotating pipe 28 to rotate integrally around the outer wall of the conveying pipe 27. The lime powder in the storage tank 42 is continuously pumped into the connecting pipe 26 and then input into the conveying pipe 27 by the pneumatic powder feeder 10. There is only one group of openings on the conveying pipe 27 facing obliquely upward. The multiple groups of first pipes 29 on the rotating pipe 28 can be communicated with the openings of the conveying pipe 27 one by one during the rotation process to ensure the stability of the pneumatic conveying.

[0037] When the first pipe 29 is communicated with the conveying pipe 27, at this time, both the first pipe 29 and the fixed pipe 16 are in the upper side 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 approaches the rotating pipe 28. 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 communicated with the side opening of the stirring pipe 12. Then 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 outwards until the lime powder is sprayed out into the sludge in the conveying cylinder 7 through the side holes 23, so as to fully mix and quench and temper the lime and the sludge. As the first pipe 29 rotates and disconnects from the conveying pipe 27, the input of the lime powder can be stopped. By controlling the power of the pneumatic powder feeder 10, the input amount of the lime powder can be controlled.

[0038] When the conveying cylinder 7 rotates, it drives the bevel gear 21 at the bottom to revolve together with the connecting ring 15. At the same time, the bevel gear 21 rolls on the first bevel gear ring 31 and the second bevel gear ring 32, thereby driving the rotating frame 11 and the stirring pipe 12 to rotate around the first pipe 29. At this time, the function of synchronously stirring the sludge during the conditioning process can be realized. During the rotation of the stirring pipe 12, it drives the pushing plate 8 to rotate together. This process does not affect the sliding of the guiding block 18 driving the pushing plate 8 in the conveying cylinder 7, and the structural connection is ingenious and stable.

[0039] It should be noted that when the conveying cylinder 7 rotates to the upper side area, at this time it is in the conditioning stage, the bevel gear 21 meshes with the first bevel gear ring 31, and the rotation speed of the bevel gear 21 is relatively fast. At this time, the moisture content of the sludge is relatively high. At the same time, during the process of the spray head 22 spraying lime powder, rapid stirring is required for mixing reaction. At this time, the pushing plate 8 is at the bottom position and will not affect the sliding of the spray head 22. After that, as the conveying cylinder 7 rotates, the bevel gear 21 gradually meshes with the second bevel gear ring 32. At this time, the moisture content of the sludge decreases and the viscosity increases. If high-speed stirring continues, it will cause greater loss to the stirring pipe 12. At this time, it indicates that it is close to the qualified conditioning state and high-speed stirring is not required. At this time, the guiding block 18 is in the arc groove 19, and the pushing plate 8 is still at the bottom position.

[0040] After that, the conveying cylinder 7 gradually rotates towards the discharge hopper 4. At this time, the guiding block 18 gradually slides from the arc groove 19 into the convex groove 20, and the pushing fixed pipe 16 and the pushing plate 8 slide together in the conveying cylinder 7 to push the relatively dry sludge out of the conveying cylinder 7 and fall 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 pushing plate 8 only needs to perform the sliding and pushing operation. After that, the conveying cylinder 7 rotates again to the position connected to the feed hopper 3 to input the sludge, and continuous conditioning operation can be carried out to improve the conditioning efficiency. In order to be able 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. Through continuous rotation and conveying, continuous conditioning operation can be ensured, and at the same time, the stirring efficiency of the internal stirring pipe 12 can be increased, and the overall service life of the equipment can be extended.

[0041] 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

[0042] See also Figures 2 - 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.

[0043] 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.

[0044] In this embodiment, the driving motor 34 drives the driving gear 35 to rotate, and the driving gear 35 drives the outer tooth ring 36, so that the rotating ring 6 and the conveying cylinder 7 can rotate as a whole. The driving gear 35 drives the worm 38 to rotate, so that the worm gear 41 rotates synchronously with the output shaft 39 and the conveying screw 40. The conveying screw 40 outputs the sludge in the discharge hopper 4. At the same time, the output torque is increased by the setting of the worm 38 and the worm gear 41, and the output power is improved. At the same time, the output rate of the sludge is synchronously regulated with the conditioning rate of the sludge. When the rotation speed of the driving motor 34 increases, the rotation speed of the conveying cylinder 7 increases, the conveying and conditioning rate of the sludge passing through the conveying cylinder 7 increases, and at the same time, the rotation speed of the conveying screw 40 increases, and the output efficiency of the sludge also increases synchronously. On the contrary, when the rotation speed of the driving motor 34 decreases, the conditioning and output rates decrease, and the overall adjustment is more convenient and efficient.
