Abstract
Description
Technical Field
[0001] This utility model relates to the field of sludge treatment technology, specifically to sludge drying and incineration treatment equipment applied to small towns. Background Technology
[0002] Sludge incineration is a common sludge disposal method. It can destroy all organic matter, kill all pathogens, and minimize the volume of sludge. The sludge with a relative moisture content of about 75% is only about 10% of the original volume. Sludge should generally be dried before incineration to reduce load and energy consumption.
[0003] Patent document CN202320363069.5, entitled "A Multifunctional Sludge Drying Device", includes a sludge drying device cylinder, a stirring mechanism, an air inlet mechanism, an upper insulation mechanism, and a lower insulation mechanism. When using this device, the discharge port needs to be closed, and the sludge is slowly added from the inlet. At the same time, the stirring motor is turned on to turn and stir the sludge, so as to carry out uniform and efficient drying treatment of the sludge.
[0004] However, the sludge itself has a high water content, and the water cannot be effectively drained before entering the drying device, which leads to an excessively long drying time for the subsequent devices, resulting in increased energy consumption and further increased costs. Therefore, the use of this sludge drying device in small towns presents a problem of excessively high cost budgets. Utility Model Content
[0005] In view of the shortcomings of the prior art, this utility model provides a sludge drying and incineration treatment device for small towns, which solves the problems existing in the prior art.
[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: a sludge drying and incineration treatment equipment applied to small towns, including a sludge drying device, wherein the sludge drying device is provided with a feed pipe and a discharge hopper, the feed pipe is provided with a squeezing mechanism, and the discharge hopper is connected to a screw conveyor II, which is connected to an incinerator. The extrusion mechanism includes a water collection trough connected to the top of the feed pipe, a drain pipe located outside the feed pipe on the water collection trough, the water collection trough being disposed on the lower cylinder, and mud discharge ports located inside the feed pipe being evenly distributed on the lower cylinder, connecting rods being evenly distributed on the lower cylinder, all of which are connected to the upper cylinder, and a filter cloth being disposed between the upper and lower cylinders, a lower block being attached to the inner wall of the lower cylinder, and an upper block being attached to the inner wall of the upper cylinder, both the upper and lower blocks being connected to a driving device, and the driving device being used to drive the upper and lower blocks to move in opposite directions, the upper cylinder being connected to a feeding pipe, and the feeding pipe being connected to a screw conveyor.

[0008] Preferably, the top of the lower block has a frustum-shaped structure.
[0009] Preferably, the driving device includes a first rack disposed on the top of the lower block, the first rack passing through the upper block and meshing with the left side of the gear, a second rack meshing with the right side of the gear, a fixed rod connecting the second rack to the upper block, and a bearing rod for connecting with the gear and a hydraulic telescopic rod connected to the second rack on the upper cylinder.
[0010] Preferably, the bottom of the upper block is provided with a sealing ring that fits and connects to the outer side of the toothed rod.
[0011] Preferably, a guide rod is provided at the top of the upper cylinder, a guide sleeve 1 is provided on the first toothed rod and sleeved on the guide rod, and a guide sleeve 2 is provided on the second toothed rod and sleeved on the guide rod, with the first guide sleeve being higher than the second guide sleeve.
[0012] This invention provides a sludge drying and incineration treatment device for small towns. Compared with the prior art, it has the following advantages: 1. This sludge drying and incineration treatment equipment, applied to small towns, delivers sludge to the upper cylinder via a screw conveyor's feeding pipe. A drive device moves the upper and lower blocks to opposite sides, compressing the sludge against the filter cloth. This allows most of the water in the sludge to be discharged into a collection tank via the filter cloth and then drained through a drain pipe. The upper and lower blocks then separate, allowing the treated sludge to be discharged through the sludge discharge port. This cycle repeats, effectively removing moisture from the sludge before it enters the sludge drying device, shortening the drying time required by subsequent devices, reducing energy consumption, saving costs, and meeting the needs of small towns.
[0013] 2. This sludge drying and incineration treatment equipment, applied to small towns, can guide the upper and lower blocks separately by setting guide rods, guide sleeve one and guide sleeve two, thereby improving the stability during extrusion. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0017] See Figures 1-4 This utility model provides the following two technical solutions: The first implementation method is a sludge drying and incineration treatment equipment applied to small towns, including a sludge drying device 1. The sludge drying device 1 can use the sludge drying technology in patent number CN202320363069.5. The sludge drying device 1 is equipped with a feed pipe 2 and a discharge hopper 3. The feed pipe 2 is equipped with a squeezing mechanism. The discharge hopper 3 is connected to a screw conveyor 6, and the screw conveyor 6 is connected to an incinerator 7. The extrusion mechanism includes a water collection tank 8 connected to the top of the feed pipe 2. A drain pipe 9 located outside the feed pipe 2 is provided on the water collection tank 8 to prevent water discharged from the drain pipe 9 from entering the feed pipe 2. The inner wall of the water collection tank 8 is provided on the outer wall of the lower cylinder 10. Sludge discharge ports 11 located inside the feed pipe 2 are evenly opened on the lower cylinder 10. Connecting rods 12 are evenly provided on the top of the lower cylinder 10. The top of each connecting rod 12 is connected to the upper cylinder 14. A filter cloth 13 for filtering water in the sludge is provided between the upper cylinder 14 and the lower cylinder 10. This is the prior art. A lower block 15 is attached to the inner wall of the lower cylinder 10, and an upper block 16 is attached to the inner wall of the upper cylinder 14. Both the upper block 16 and the lower block 15 are connected to the drive device, and the drive device is used to drive the upper block 16 and the lower block 15 to move in opposite directions. The upper cylinder 14 is connected to the feeding pipe 4, and the feeding pipe 4 is connected to the screw conveyor 5.
[0018] Both screw conveyor 5 and screw conveyor 6 are equipped with frames to fix screw conveyor 5 and screw conveyor 6 respectively.
[0019] The top of the lower block 15 has a frustum-shaped structure to prevent sludge residue from remaining on the top of the lower block 15.
[0020] The driving device includes a first rack 18 disposed on the top of the lower block 15. The first rack 18 passes through the upper block 16 and meshes with the left side of the gear 22. The right side of the gear 22 is meshed with a second rack 21. A fixed rod 20 connects the second rack 21 and the upper block 16. The upper cylinder 14 is provided with a bearing rod 24 for connecting with the gear 22 and a hydraulic telescopic rod 23 for connecting with the second rack 21. The hydraulic telescopic rod 23 is configured in the prior art, which drives the second rack 21 to descend, so that the gear 22 can drive the first rack 18 to rise, and then drive the upper block 16 to descend and the lower block 15 to rise through the fixed rod 20.
[0021] The bottom of the upper block 16 is provided with a sealing ring 19 that fits and connects to the outside of the toothed rod 18 to prevent mud and water from entering the upper block 16.
[0022] The second embodiment differs from the first embodiment in that: a guide rod 25 is provided at the top of the upper cylinder 14, a guide sleeve 26 is provided on the toothed rod 18 and sleeved on the guide rod 25, and a guide sleeve 27 is provided on the toothed rod 21 and sleeved on the guide rod 25. The guide sleeve 26 is higher than the guide sleeve 27. The guide sleeve 26 moves upward along the guide rod 25 with the toothed rod 18, and the guide sleeve 27 moves downward along the guide rod 25 with the toothed rod 21. This can guide the lower block 15 and the upper block 16 respectively, improving the stability during extrusion.
[0023] Furthermore, all content not described in detail in this specification is existing technology known to those skilled in the art, and the model parameters of each electrical appliance are not specifically limited; conventional equipment can be used.
[0024] Before use, drive the lower block 15 and upper block 16 to move towards each other until the lower block 15 blocks the sludge discharge port 11. At this time, the upper block 16 is still above the feeding pipe 4. The sludge is transported by the screw conveyor 5. The sludge enters the upper cylinder 14 through the feeding pipe 4 and finally falls to the top of the lower block 15. After a certain amount of sludge is transported, stop transporting the sludge and move the lower block 15 and upper block 16 towards each other. At this time, the sludge can be squeezed and dewatered at the filter cloth 13. The water is collected through the water collection tank 8 and discharged through the drain pipe 9. During the squeezing and dewatering process, the upper block 16... Blocking the feed pipe 4 prevents sludge from entering the upper block 16. After dewatering, the lower block 15 can be removed from blocking the sludge discharge port 11, allowing the dewatered sludge to be discharged into the feed pipe 2 and then into the sludge drying device 1 for drying. Repeating the above steps can effectively remove moisture from the incoming sludge, shortening the time required for subsequent sludge drying, reducing energy consumption, saving costs, and meeting the needs of small towns. After the sludge is dried by the sludge drying device 1, it is conveyed to the incinerator 7 by the screw conveyor 6 for incineration.
