Description

Technical Field

[0001] The invention relates to the technical field of sludge drying equipment, in particular to a circulating subdivision device for dried water-containing sludge. Background Art

[0002] Sludge drying equipment is an environmentally friendly equipment that can remove moisture from sludge and dry it. This equipment usually uses hot air drying to evaporate the moisture in the sludge through the penetration of high-temperature hot air and convection heat exchange, and discharge the evaporated water vapor. During the drying process, the drying speed and effect can also be controlled by adjusting parameters such as temperature, humidity and air volume. In addition, the sludge drying equipment is also equipped with a special dust removal system that can effectively collect and treat the dust generated during the drying process to prevent environmental pollution. The use of sludge drying equipment can not only reduce the volume of sludge and reduce the burden of transportation and treatment, but also use the dried sludge as a resource, such as for making fertilizers, building materials, etc., to achieve waste resource utilization. Therefore, sludge drying equipment has broad application prospects in sewage treatment, environmental protection and other fields.

[0003] Existing municipal, domestic and other types of sludge drying devices mainly use converter systems. These systems rely on the rotating action of the converter to lift and drop materials in the narrow arc space inside the furnace, and achieve dehydration and drying through this reciprocating process and heat energy transfer. However, due to the high water content of the sludge itself, it is easy to condense into lumps. When the sludge sticks to each other to form lumps, only the material on the surface of the large block can effectively absorb heat. Therefore, the actual effective heating area is significantly reduced, thereby reducing the efficiency of sludge drying.

[0030] The present invention will be further described below with reference to the accompanying drawings in the embodiments of the present invention.

[0031] See also Figures 1 to 3 In the embodiment of the present invention, a circulating subdivision device for dried water sludge includes a drying and incineration reactor 1, a wet material and dry material mixer 2, a secondary dry material conveyor 3, a primary dry material conveyor 4, a primary slag discharger 5, a slag separation mechanism 7 and a secondary slag discharger 6. The drying and incineration reactor 1 is used to incinerate and dry the sludge. The wet material and dry material mixer 2 is used to evenly mix the wet material containing a high moisture content with the material in a dry state. The dry material conveyor can be a belt conveyor, a screw conveyor, etc., which is not specifically limited. The slag discharger is used to output the dried dry slag material. The specific structures and working principles of the dry incineration reactor 1, the wet material and dry material mixer 2, the secondary dry material conveyor 3, the primary dry material conveyor 4, the primary slag discharger 5 and the secondary slag discharger 6 are all prior art, so they are not described in detail. The discharge end of the wet material and dry material mixer 2 is connected to the feed end of the dry incineration reactor 1, and the feed end of the wet material and dry material mixer 2 simultaneously inputs dry slag and wet sludge. The top of the slag separation mechanism 7 is provided with a slag inlet 9, the discharge end of the dry incineration reactor 1 is connected to the slag inlet 9, and the bottom of the slag separation mechanism 7 is provided with a primary slag discharger 11 The first slag outlet 11 is connected to the feed end of the first slag discharger 5, the second slag outlet 10 is connected to the feed end of the second slag discharger 6, the discharge end of the first slag outlet 11 is connected to the feed end of the first dry material conveyor 4, the feed end of the second dry material conveyor 3 is connected to the discharge end of the first dry material conveyor 4, the discharge end of the second dry material conveyor 3 is connected to the feed end of the wet material dry material mixer 2, and the dry slag output from the first slag outlet 11 is input into the wet material dry material mixer 2 through the first dry material conveyor 4 and the second dry material conveyor 3 to mix with the wet sludge. , and then input into the drying and incineration reactor 1 for incineration and drying. Through the primary slag outlet 11 and the secondary slag outlet 10 arranged on the slag separation mechanism 7, one transports the dry slag to the designated position through the secondary slag discharger 6 for recycling, and the other transports the dry slag to the wet material dry material mixer 2 through the primary and secondary dry material conveyors 3, and the dry material and the wet material are fully mixed through the mixer to make the sludge relatively loose, which is greatly beneficial for the sludge to be dispersed in the reactor, facilitating better and faster heat absorption and drying, and at the same time, the preheating of the dry slag can be transferred to the wet and cold sludge, achieving energy-saving effect.

[0032] In this embodiment, preferably, refer to Figure 3 , Figure 8 and Fig. 9The slag separation mechanism 7 includes a slag separation box 8, a first-level slag outlet 11 and a second-level slag outlet 10 are both connected and arranged at the bottom of the slag separation box 8, and a slag inlet 9 is connected and arranged at the top of the slag separation box 8. The interior of the slag separation box 8 is provided with an equal distribution and a material distribution ratio adjustment component; the material distribution ratio adjustment component includes an adjustment plate 28, a traction rope 29 and an electric push rod 27. The bottom end of the adjustment plate 28 is rotatably connected to the slag separation box 8 through a connecting pin 30. A torsion spring 31 is sleeved on the connecting pin 30. One end of the torsion spring 31 is fixedly connected to the connecting pin 30, and the other end of the torsion spring 31 is fixedly connected to the box wall of the slag separation box 8. Under the action of the torsion spring 31, when the traction rope 29 is relaxed, the adjustment plate 28 can rotate to the left. The electric push rod 27 is fixedly installed on one side wall of the slag separation box 8, one end of the traction rope 29 is fixedly connected to the output end of the electric push rod 27, and the other end of the traction rope 29 is fixedly connected to the top of the adjustment plate 28. The traction rope 29 passes through the slag separation box The dry slag material dried by the drying incineration reactor 1 is input into the slag box 8 through the slag inlet 9. After being dispersed by the evenly distributed material drop assembly, the dry slag material falls evenly. The dry slag material on the left side of the adjustment plate 28 enters the secondary slag outlet 10, and the dry slag material on the right side of the adjustment plate 28 enters the primary slag outlet 11. For sludge with different water contents, the amount of dry slag material required to be mixed into the wet material dry material mixer 2 is different. When the sludge water content input into the drying incineration reactor 1 is low When the amount of dry slag to be input is small, the output end of the electric push rod 27 can be controlled to contract, thereby driving one end of the traction rope 29 to move upward, thereby pulling the adjustment plate 28 to rotate right. At this time, the area of ​​the feed opening above the first-level slag outlet 11 is reduced, thereby reducing the amount of dry slag entering the first-level slag outlet 11, and then reducing the amount of dry slag input into the wet material and dry material mixer 2, so as to prevent excessive dry slag input into the dry incineration reactor 1 from reducing the sludge treatment efficiency.

[0033] In this embodiment, preferably, please refer to Figures 3 to 5The evenly distributed material distribution component includes a slag dividing plate 12 and a plurality of rotating shafts 15. The slag dividing plate 12 is provided with a plurality of slag discharge holes 1201, and the plurality of slag discharge holes 1201 are distributed in a rectangular array. A material discharge tray 16 is arranged in the slag discharge holes 1201. The plurality of rotating shafts 15 are arranged in parallel with each other, and the rotating shafts 15 pass through the slag discharge holes 1201 in the slag dividing plate 12 and are rotatably connected to the slag dividing plate 12. A driving mechanism for driving the plurality of rotating shafts 15 to rotate is arranged on one side of the slag dividing box 8; the driving mechanism includes a transmission box, a transmission wheel 13, a transmission belt 14 and a motor 17, the transmission box is fixedly mounted on one side of the slag dividing box 8, one end of the rotating shaft 15 extends into the transmission box, and two adjacent rotating shafts 15 are connected by transmission through the transmission wheel 13 and the transmission belt 14, the motor 17 is fixedly mounted on one side of the transmission box, and the output end of the motor 17 is fixedly connected to one of the rotating shafts 15; when the dry slag is injected into the slag dividing box through the slag inlet 9 When the slag is in the box 8, the discharge tray 16 is first rotated to a horizontal state to close the slag discharge hole 1201. When a certain amount of dry slag is accumulated above the slag separating plate 12, the motor 17 is turned on. The output end of the motor 17 drives one of the rotating shafts 15 to rotate. When the rotating shaft 15 rotates, it drives the other rotating shafts 15 to rotate synchronously through the transmission belt 14 and the transmission wheel 13, thereby driving all the discharge trays 16 to rotate synchronously. As the discharge tray 16 rotates, the dry slag above the discharge tray 16 is rotated and driven to the bottom of the discharge tray 16 and falls downward, so that the amount of dry slag output from each slag discharge hole 1201 is similar, and the amount of dry slag falling at each position below the slag separating plate 12 is similar, so that the ratio of dry slag entering the primary slag discharge port 11 and the secondary slag discharge port 10 remains fixed, so that the amount of dry slag input into the wet material and dry material mixer 2 remains constant, so as to avoid the unstable amount of dry slag input affecting the sludge drying efficiency.

[0034] In this embodiment, preferably, an ultrasonic sensor 32 is embedded and installed on the box wall of the slag separating box 8, and a receiver is arranged at a corresponding position on the box wall opposite to the ultrasonic sensor 32. The height of the ultrasonic sensor 32 is higher than the height of the slag separating plate 12. The ultrasonic sensor 32 uses the characteristics of ultrasonic waves when propagating in the medium to measure the moisture content of the material. In the sludge powder, the amount of moisture directly affects the conduction speed of its ultrasonic waves. Therefore, its moisture content can be calculated by measuring the time it takes for ultrasonic waves to propagate in the sludge. The ultrasonic sensor 32 is connected to the electric push rod 27 signal through the PLC controller to adjust the slag discharge ratio of the first slag outlet 11 and the second slag outlet 10. The higher the moisture content of the dry slag input into the slag separating box 8, the more dry slag input into the wet material and dry material mixer 2, thereby automatically adjusting the amount of dry slag input into the wet material and dry material mixer 2, effectively improving the drying efficiency. It should be noted that the detection process is carried out when a certain amount of dry slag is accumulated on the slag separating plate 12.

[0035] Since the slag inlet 9 is a circular structure and the dry slag input through the slag inlet 9 has poor dispersion, the dry slag falling onto the slag separating plate 12 is uneven. Especially when the dry slag on the slag separating plate 12 is about to fall off, it is easy for only the area below the slag inlet 9 to have dry slag, resulting in uneven distribution ratio of subsequent dry slag. In order to solve this problem, the following embodiments are provided.

[0036] See also Figure 3 and Figure 7 In the embodiment of the present invention, two symmetrical material-dividing plates 22 are arranged below the slag inlet 9 in the slag-dividing box 8, and driving columns 21 are fixedly installed on the top of the two material-dividing plates 22. The length of the driving column 21 is half the length of the material-dividing plate 22. The two driving columns 21 are coaxially arranged, and the ends of the two driving columns 21 that are close to each other are rotatably connected by a connecting shaft 23. The slag-dividing box 8 is provided with a driving assembly for driving the two driving columns 21 to rotate synchronously in opposite directions; the driving assembly includes a hydraulic push rod 33, a driving frame 18, a rack 19 and a gear 20. The hydraulic push rod 33 is fixedly installed on the top of the slag-dividing box 8, and the output end of the hydraulic push rod 33 is fixedly connected to the middle part of the driving frame 18. Racks 19 are fixedly installed at both ends of the frame 18, and the two driving columns 21 respectively penetrate the two opposite side walls of the slag box 8, and gears 20 are fixedly installed on one end of the two driving columns 21 extending out of the slag box 8. The two racks 19 have different heights, one rack 19 is meshed with the gear 20 above it, and the other rack 19 is meshed with the gear 20 below it, so that when the driving frame 18 drives the rack 19 to move, the two gears 20 rotate in opposite directions, so that the two driving columns 21 drive the two material stripping plates 22 to rotate in the opposite direction, and the two material stripping plates 22 rotate back and forth at a uniform speed, so that the dry slag falling downward from the slag inlet 9 can be evenly dropped downward and dispersed on the slag stripping plate 12 under the movement of the material stripping plate 22.

[0037] In this embodiment, preferably, a sliding frame 24 is slidably installed inside the slag separating box 8, and the sliding frame 24 is arranged between the material removing plate 22 and the slag separating plate 12. A wire dividing net 26 is fixedly installed inside the sliding frame 24, and the wire dividing net 26 includes a plurality of transverse steel wires and a plurality of longitudinal steel wires, and the transverse steel wires and the longitudinal steel wires are staggered. Two connecting rods 25 are hinged to the middle of both sides of the sliding frame 24, and the top ends of the two connecting rods 25 are respectively hinged to the bottoms of the two material removing plates 22. When the two material removing plates 22 rotate, the sliding frame 24 can be driven to rise and fall through the connecting rod 25, thereby driving the wire dividing net 26 to rise and fall, so that the wire dividing net 26 can separate the dry material slag above the slag separating plate 12 to prevent part of the dry material slag from agglomerating and causing the slag outlet 1201 to be blocked. The lifting and lowering of the slag separating plate 12 is driven by the rotation of the material removing plate 22, and no other driving elements are required to drive it. The synchronization is good and the cost is reduced.

[0038] Working principle:

[0039] 1. Mixing of dry and wet materials: First, the wet sludge with high water content is evenly mixed with the dry residue through the wet material dry material mixer 2. The discharge end of the mixer is connected to the feed end of the dry incineration reactor 1 to ensure that the two are fully mixed before entering the next treatment process.

[0040] 2. Drying and incineration: The mixed materials are sent to the drying and incineration reactor 1 for incineration and drying. This process is designed to reduce the moisture content in the sludge and convert it into a form that is easier to handle and transport.

[0041] 3. Slag separation: The dry slag obtained after drying and incineration is sent to the slag separation mechanism 7. The slag separation mechanism 7 is provided with an evenly distributed material drop component and a material distribution ratio adjustment component, which are used to evenly disperse the dry slag and divide it into two parts according to the proportion: one part enters the primary slag outlet 11, and the other part enters the secondary slag outlet 10.

[0042] 4. Transportation and circulation: The dry slag output from the primary slag outlet 11 is sent to the wet material dry material mixer 2 through the primary dry material conveyor 4, and mixed with new wet sludge again to achieve recycling. The dry slag output from the secondary slag outlet 10 is transported to a designated location through the secondary slag discharger 6 for treatment or utilization.

[0043] 5. Intelligent control: An ultrasonic sensor 32 is integrated in the slag box 8 to monitor the moisture content of the dry slag in real time, and is connected to the electric push rod 27 through the PLC controller to automatically adjust the slag discharge ratio of the first slag outlet 11 and the second slag outlet 10. This intelligent control ensures that the dry slag input is adjusted according to the actual moisture content and optimizes the drying efficiency.

[0044] 6. Prevent uneven distribution and blockage: In order to solve the problem of uneven distribution of dry slag and blockage of the slag discharge hole 1201, this solution sets two symmetrical material-dispensing plates 22 and a combination of a sliding frame 24 and a steel wire dividing net 26 in the slag separation box 8. Through the cooperation of components such as the driving column 21, the hydraulic push rod 33, the rack 19 and the gear 20, the uniform reciprocating rotation of the material-dispensing plate 22 and the lifting and lowering movement of the sliding frame 24 and the steel wire dividing net 26 are realized, thereby ensuring the uniform distribution of the dry slag on the slag separation plate 12 and effectively preventing the slag discharge hole 1201 from being blocked.

[0045] The above description is only a preferred embodiment of the present invention, so all equivalent changes or modifications made according to the structure, characteristics and principles described in the scope of the patent application of the present invention are included in the scope of the patent application of the present invention.
