Description

Technical Field

[0001] The present invention relates to the technical field of comprehensive utilization of sludge incineration ash, and specifically relates to an equipment for comprehensive utilization of municipal sludge incineration ash. Background Art

[0002] With the acceleration of the urbanization process, the number and scale of municipal sewage treatment plants have been continuously expanding, and the resulting municipal sludge (i.e., domestic sludge) has also shown a rapid growth trend. Municipal sludge mainly comes from the by-products generated during the treatment of urban domestic sewage, where organic matter and suspended solids in the sewage are removed through physical, chemical, and biological treatment methods. According to relevant statistical data, the amount of municipal sludge generated globally each year is in the hundreds of millions of tons, and this figure is still rising.

[0003] Sludge incineration is a method of thermally oxidizing and decomposing organic substances in sludge, which can effectively reduce the volume of sludge, kill pathogenic microorganisms, and convert harmful substances into a relatively stable form. Generally, the incinerated ash is directly discarded, which not only pollutes the environment but also causes waste of resources. Therefore, the existing technology uses the incinerated ash of sludge for resource recycling, combines it with certain materials and water, and makes bricks. And the existing brick processing equipment is used to make bricks. The production process of bricks is as follows: first, the sludge incineration ash, materials, and water are mixed and stirred, then the stirred raw materials are extruded and the extruded raw materials are conveyed. During the conveying process, the raw materials are cut to form individual bricks, and then the bricks are air-dried and fired, and finally bricks are formed.

[0004] The existing technology with the publication number of CN116330432A includes a support body, a driving mechanism arranged on the support body, a stirring mechanism arranged on the support body, a first conveying mechanism arranged on the support body, a second conveying mechanism arranged on the support body, and a cutting mechanism arranged on the support body; the driving mechanism includes a first base arranged on the support body and a first motor arranged on the first base; the stirring mechanism includes a stirring barrel fixedly arranged on the support body, a feeding barrel fixedly arranged on the stirring barrel, a feeding pipe with one end communicated with the stirring barrel and the other end communicated with the feeding barrel, an annular frame slidably arranged on the stirring barrel, and a stirring component slidably arranged on the annular frame.

[0005] When the above device is used, the stirred materials are conveyed and extruded through the first conveying mechanism, then conveyed through the second conveying mechanism, and horizontally and vertically cut through the cutting mechanism, and finally individual bricks are formed. However, in the actual use process, due to the large difference in the morphology of the sludge incineration ash, which is mostly loose, porous, and agglomerated, the high porosity and large specific surface area of the ash result in an increase in the water absorption rate of the bricks, affecting the durability and quality of the subsequent use of the bricks. Therefore, it is difficult to grind and refine the ash. Summary of the Invention

[0011] Preferably, a water outlet hole for communicating the L-shaped tube with the interior of the U-shaped tube is opened on one side of each U-shaped tube close to the L-shaped tube. The bottom ends of the two U-shaped tubes are fixedly communicated with sprinkler heads for uniformly spraying water on the bottom of the mixing barrel.

[0012] Preferably, extrusion blocks are horizontally movably connected to symmetric positions at both ends of the inner wall of the rectangular housing. Tooth plate are fixedly connected to symmetric positions at the bottoms of the extrusion blocks at both ends, and an activity groove for the horizontal movement of the tooth plate is formed at the bottom of the rectangular housing. A gear for pulling the extrusion blocks at both ends to move towards or away from each other is fixedly connected to the bottom of the rectangular housing in a fixed-axis rotation manner. An extrusion mechanism for pulling the extrusion blocks to extrude and form the sludge incineration ash is provided on the rectangular housing.

[0013] Preferably, the extrusion mechanism includes cranks that are penetrated and fixedly connected to symmetric positions on both sides at one end of the rectangular housing in a fixed-axis rotation manner. Connecting rods for pulling the extrusion blocks to extrude and form the sludge incineration ash are coaxially rotatably connected to symmetric positions at the ends of the cranks on both sides.

A support groove for movably supporting the inclined panel is formed at one end of the rectangular housing away from the worm gear.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0017] First, by pulling the spline sleeve and the grinding head to move up and down through the pull rod, the efficient rolling and crushing of the sludge incineration ash are realized, significantly improving the fineness and uniformity of the ash. The fineness control is crucial for the subsequent building material utilization because it directly affects the strength and durability of building material products such as bricks. By converting the ash into fine powder meeting the building material standards, the resource utilization rate of the ash is significantly improved. This fineness control not only improves the applicability of the ash as a building material raw material but also increases its economic value, transforming the waste originally needing to be disposed of into valuable resources.

[0018] II. The uniform water addition to the bottom of the mixing barrel is achieved through the sprinkler heads on the U-shaped pipe. Combined with the stirring effect of the stirring rod, it ensures the full mixing of ash slag, water and other additives, improving the comprehensive utilization effect of sludge incineration ash slag. Uniform mixing is crucial for improving the quality of the final building materials, as it can prevent uneven brick strength and reduced durability caused by uneven distribution of moisture and additives, thereby extending the service life of building materials and reducing maintenance and replacement costs.

[0019] III. Through the coordinated work of the crank, connecting rod and gear, the automatic extrusion molding of the mixed sludge incineration ash slag is realized. The automatic operation not only reduces manual intervention and labor intensity, but also improves the brick production efficiency and the finished product rate. The automatic extrusion molding process ensures the consistency of brick size and the regularity of shape, further enhancing the utilization rate of sludge incineration ash slag.

[0020] By using the above structures in combination, the problems existing in the existing device during actual use are solved. Due to the large differences in the morphology of ash slag after sludge incineration, which are mostly loose, porous and agglomerated, the high porosity and large specific surface area of the ash slag lead to an increase in the water absorption rate of the bricks, affecting the durability and quality of the subsequent brick use. Therefore, it is difficult to grind and refine the ash slag. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] Embodiment 2: On the basis of Embodiment 1, further:

[0034] The lifting mechanism includes a cylindrical block 13 fixedly connected to the outer contour of the spline shaft 5 near the end. An M-shaped groove 131 is formed in the cylindrical block 13. The inner walls of both sides of the M-shaped groove 131 are movably supported by pull rods 14 for pulling the spline sleeve 6 to move up and down. A rotating ring 12 is rotatably connected to the outer contour of the end of the spline sleeve 6. One ends of the two pull rods 14 away from the cylindrical block 13 are respectively fixedly connected to the adjacent sides of the rotating ring 12.

[0035] Both sides of the conical grinding sleeve 4 and the guide hopper 8 at symmetrical positions are penetrated and fixedly connected with cylindrical tubes 9. The inner walls of the two cylindrical tubes 9 are connected with a U-shaped tube 11 for supporting the rotating ring 12 in a lifting manner. The opposite ends of the two U-shaped tubes 11 are respectively fixedly connected to the adjacent sides of the rotating ring 12.

[0036] During use, through the cylindrical tube 9 provided on the conical grinding sleeve 4 and the material guiding hopper 8, the cylindrical tube 9 is fixedly supported on the conical grinding sleeve 4 and the material guiding hopper 8. Through the U-shaped tube 11 provided on the cylindrical tube 9, the U-shaped tube 11 is connected to move up and down on the inner wall of the cylindrical tube 9. And the rotating ring 12 provided on the spline sleeve 6, then the rotating ring 12 is rotatably supported on the spline sleeve 6, and the U-shaped tube 11 supports the rotating ring 12 to prevent the rotating ring 12 from rotating synchronously with the spline sleeve 6. Through the cylindrical block 13 provided on the spline shaft 5, the spline shaft 5 can drive the cylindrical block 13 to rotate about a fixed axis synchronously. Through the M-shaped groove 131 opened on the cylindrical block 13 and the pull rod 14 provided on the M-shaped groove 131, the pull rod 14 is fixedly supported on the rotating ring 12. Along with the cylindrical block 13 rotating about a fixed axis, the pull rod 14 can pull the rotating ring 12 and the spline sleeve 6 to move up and down synchronously under the action of the M-shaped groove 131.

[0037] As Figure 2 and Figure 3 shown, when the spline sleeve 6 moves downward, and the gap between the conical grinding head 7 and the inner wall of the conical grinding sleeve 4 increases, the mixed material inside the material guiding hopper 8 falls between the conical grinding head 7 and the inner wall of the conical grinding sleeve 4 under the action of gravity. At this time, when the spline sleeve 6 pulls the conical grinding head 7 to move upward, and the gap between the conical grinding head 7 and the inner wall of the conical grinding sleeve 4 decreases.

The relative ends of the two L-shaped tubes 15 penetrate to the inner walls of the adjacent cylindrical tubes 9 and are fixedly connected respectively. The ends of the two L-shaped tubes 15 far from the cylindrical tubes 9 are penetrated and fixedly connected with water storage barrels 16 for storing water sources. The U-shaped tube 11 is provided with a water injection mechanism for adding water to the bottom of the mixing barrel 2 at a constant speed.

[0040] On each side of the U-shaped tube 11 near the L-shaped tube 15, a water outlet hole 111 is provided to connect the inside of the L-shaped tube 15 and the U-shaped tube 11. At the bottom ends of the two U-shaped tubes 11, a sprinkler head 10 is fixedly connected to evenly sprinkle water on the bottom of the mixing barrel 2.

[0041] During use, through the L-shaped tube 15 provided on the mixing barrel 2, the L-shaped tube 15 is fixedly supported on the mixing barrel 2.

Along with the spline sleeve 6 driving the conical grinding head 7 to move downward for feeding, and the U-shaped tube 11 drives the water outlet hole 111 to move downward to be in a corresponding position with the L-shaped tube 15, the L-shaped tube 15 can discharge the water source inside the water storage barrel 16 to the inner wall of the U-shaped tube 11. And the sprinkler head 10 provided on the U-shaped tube 11 enables the sprinkler head 10 to evenly sprinkle the water source on the mixed materials at the bottom of the mixing barrel 2. Along with the stirring rod 17 stirring the bottom fertilizer, the mixing effect of the water source and the materials is further improved.

[0043] Example 4: On the basis of Example 3, further:

[0044] On both ends of the inner wall of the rectangular housing 1 at symmetric positions, extrusion blocks 18 are horizontally movably connected. At symmetric positions at the bottom of both ends of the extrusion blocks 18, tooth plates 19 are fixedly connected. And an activity groove 101 for the horizontal movement of the tooth plates 19 is provided at the bottom of the rectangular housing 1. A gear 20 for pulling the two ends of the extrusion blocks 18 to move towards or away from each other is fixedly connected in a rotating manner at the bottom of the rectangular housing 1. An extrusion mechanism for pulling the extrusion blocks 18 to extrude and form the sludge incineration ash residue is provided on the rectangular housing 1.

[0045] The extrusion mechanism includes that on both sides of one end of a rectangular housing 1, there are through holes and fixed-axis rotation connections with crank 21. On the symmetric positions at the ends of both cranks 21, there are coaxial rotation connections with connecting rods 22 for pulling and extruding sludge incineration ash residue to form a shape. And on both symmetric positions of the rectangular housing 1 near one end of the crank 21, there are rectangular through slots 102 for the connecting rod 22 to move. The rectangular housing 1 is penetrated and rotatably connected with a worm 24 for driving the crank 21 to rotate around a fixed axis. On the crank 21, there is a coaxially fixed worm gear 23 meshing with the worm 24. On the corresponding positions near the ends of the worm 24 and the spline shaft 5, there are fixed belt pulleys 25. A transmission belt 26 is sleeved on the outer contours of the two belt pulleys 25 for driving the worm 24 and the belt pulley 25 to rotate synchronously.

[0046] During use, through the extrusion block 18 provided on the rectangular housing 1, the extrusion block 18 is horizontally movably connected to the inner wall of the rectangular housing 1. Through the worm 24 provided on the rectangular housing 1, through the belt pulleys 25 provided on the spline shaft 5 and the worm 24, and the transmission belt 26 provided on the belt pulley 25, along with the spline shaft 5 rotating around a fixed axis, the transmission belt 26 can drive the worm 24 to rotate around a fixed axis synchronously under the action of the spline shaft 5. And the crank 21 provided on the rectangular housing 1 is fixedly rotationally connected to the rectangular housing 1.

[0047] When the extrusion blocks 18 at both ends move away from each other to the limit distance, at this time, the extrusion block 18 near one end of the connecting rod 22 is separated from the mixing barrel 2. At this time, the mixed material at the bottom of the connecting rod 22 drops quantitatively onto the inner wall of the rectangular housing 1 under the action of gravity. Along with the extrusion blocks 18 moving towards each other, the extrusion blocks 18 moving towards each other can extrude the mixed material inside the rectangular housing 1 into bricks. During this process, the top side of the extrusion block 18 near one end of the connecting rod 22 is in contact with the bottom of the mixing barrel 2 for sealing, preventing the mixed material at the bottom of the mixing barrel 2 from leaking.

[0048] Embodiment 5: On the basis of Embodiment 4, further:

[0049] The two symmetric positions on both sides of the rectangular housing 1 are penetrated and horizontally movably connected with a U-shaped frame 27, and a fixed rod 28 is fixedly connected to the position corresponding to the U-shaped frame 27 on one side of the rectangular housing 1. A spring 29 for guiding the U-shaped frame 27 to move back is fixedly connected to the opposite surface of the fixed rod 28 and one side of the U-shaped frame 27. A movable block 30 is fixedly connected to one side of the U-shaped frame 27 close to the fixed rod 28, and a limit groove 103 for movably supporting the movable block 30 is provided at the position corresponding to the U-shaped frame 27 on the rectangular housing 1.

[0050] A bevel panel 31 for pushing the U-shaped frame 27 to move and fit against the inner wall of the rectangular housing 1 is fixedly connected to the extrusion block 18 at one end far from the worm wheel 23, and a support groove 104 for movably supporting the bevel panel 31 is provided at one end of the rectangular housing 1 far from the worm wheel 23.

[0051] When in use, through the U-shaped frame 27 provided on the rectangular housing 1, the U-shaped frame 27 fits against the inner wall of the rectangular housing 1. At the same time, the U-shaped frame 27 is horizontally movably connected to the rectangular housing 1. Through the fixed rod 28 provided on the rectangular housing 1 and the spring 29 provided on the fixed rod 28, the spring 29 can support the position of the fixed rod 28. Through the movable block 30 provided on the U-shaped frame 27 and the limit groove 103 provided on the rectangular housing 1, the limit groove 103 can limit and support the moving direction of the movable block 30. Through the bevel panel 31 provided on the extrusion block 18 and the support groove 104 provided on the rectangular housing 1, the bevel panel 31 is fixedly supported on the extrusion block 18, and at the same time, the support groove 104 movably supports the bevel panel 31.

[0052] Such as Figures 7 - 8As shown, when the extrusion blocks 18 move towards each other, first, the inclined panel 31 moves under the action of the extrusion blocks 18 and contacts the movable block 30, enabling the movable block 30 to pull the U-shaped frame 27 to move to the inner wall of the rectangular housing 1 under the action of the inclined surface of the inclined panel 31. Then, the spring 29 is in a compressed and contracted state under the action of the U-shaped frame 27. At this time, the U-shaped frame 27 fits against the inner wall of the rectangular housing 1, enabling the extrusion blocks 18 to push the mixed material into the inner wall of the U-shaped frame 27 for extrusion molding. The formed bricks are located on the inner wall of the U-shaped frame 27. When the extrusion blocks 18 finish extruding the bricks, as the extrusion blocks 18 move away from each other, and the inclined panel 31 disengages from the movable block 30. At the same time, the elastic force of the spring 29 is greater than the weight of the U-shaped frame 27 and the bricks. Thus, the U-shaped frame 27 moves towards the side away from the fixed rod 28 under the elastic force of the spring 29. When the U-shaped frame 27 rotates and moves out of the inner wall of the rectangular housing 1, the bricks inside the U-shaped frame 27 can be discharged under the action of gravity. Through the combined use of the above structure, automatic discharging of the formed bricks is achieved.

[0053] Furthermore, it is realized that during the actual use of the existing device, the ash residue can be ground and refined, which is convenient to use and better than traditional products.

[0054] The standard parts used in this embodiment can be directly purchased from the market. For the non-standard structural components described in the specification and drawings, they can also be directly processed without any doubt based on the existing technical knowledge. At the same time, the connection methods of each component adopt the mature conventional means in the existing technology, and the machines, parts, and equipment all adopt the conventional models in the existing technology. Therefore, no specific description will be made here.

[0055] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
