Description

Technical Field

[0001] The invention relates to the technical field of comprehensive utilization of sludge incineration ash, and in particular to a comprehensive utilization device for municipal sludge incineration ash. Background Art

[0002] With the acceleration of urbanization, the number and scale of municipal sewage treatment plants are constantly expanding, and the municipal sludge (i.e. domestic sludge) generated is also showing a rapid growth trend. Municipal sludge mainly comes from the byproduct generated by removing organic matter and suspended solids in sewage through physical, chemical and biological treatment methods during the treatment of urban domestic sewage. According to relevant statistics, the amount of municipal sludge generated worldwide each year is in the billions of tons, and this number continues to rise.

[0003] Sludge incineration is a method of decomposing organic matter in sludge by high-temperature oxidation. It can effectively reduce the volume of sludge, kill pathogenic microorganisms, and convert harmful substances into relatively stable forms. Generally, the ash after incineration will be thrown away directly, which not only pollutes the environment, but also causes a waste of resources. Therefore, the ash after sludge incineration is used for resource recycling, combined with certain materials and water, and made into bricks. In addition, brick processing equipment is currently used to make bricks. The production process of bricks is as follows: first, the sludge incineration ash, materials and water are mixed and stirred, and then the stirred raw materials are extruded and transported. During the transportation process, the raw materials are cut and formed into bricks one by one, and then the bricks are air-dried and fired to form bricks.

[0004] The existing Chinese patent with publication number 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 loading barrel fixedly arranged on the stirring barrel, a feeding pipe with one end connected to the stirring barrel and the other end connected to the loading barrel, an annular frame slidably arranged on the stirring barrel, and a stirring component slidably arranged on the annular frame.

[0005] When the above-mentioned device is in use, the stirred material is conveyed and extruded through the first conveying mechanism, and then conveyed through the second conveying mechanism, and cut horizontally and vertically through the cutting mechanism, and finally bricks are formed one by one. However, in actual use, due to the large differences in the morphology of ash after sludge incineration, most of them are loose, porous and agglomerated. The high porosity and large specific surface area of ​​the ash increase the water absorption rate of the bricks, affecting the durability and quality of the subsequent bricks. Therefore, it is difficult to grind the ash. Summary of the invention

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. By pulling the spline sleeve and the grinding head up and down by the pull rod, the sludge incineration ash is efficiently crushed and crushed, which significantly improves the fineness and uniformity of the ash. Fineness control is crucial for subsequent building material utilization because it directly affects the strength and durability of building materials such as bricks. By converting the ash into fine powder that meets 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 raw material for building materials, but also increases its economic value, turning waste that originally needed to be disposed of into valuable resources.

[0018] 2. The sprinkler head on the U-shaped tube is used to evenly add water to the bottom of the mixing barrel. The stirring action of the stirring rod ensures that the ash is fully mixed with water and other additives, thereby improving the comprehensive utilization of sludge incineration ash. Uniform mixing is essential to improving the quality of the final building material products, because it can prevent uneven strength and durability of bricks caused by uneven distribution of moisture and additives, thereby extending the service life of building materials and reducing maintenance and replacement costs.

[0019] 3. Through the coordinated work of cranks, connecting rods and gears, the mixed sludge incineration ash is automatically extruded and formed. The automated operation not only reduces manual intervention and labor intensity, but also improves the production efficiency and yield of bricks. The automated extrusion process ensures the consistency of brick size and regularity of shape, further improving the utilization rate of sludge incineration ash.

[0020] The coordinated use of the above-mentioned structure solves the problem that in the actual use of the existing device, due to the large differences in the morphology of the ash after sludge incineration, most of which are loose, porous and agglomerated, the high porosity and large specific surface area of ​​the ash increase the water absorption rate of the bricks, affecting the durability and quality of the subsequent bricks, and therefore it is difficult to grind the ash.

A spline shaft 5 is provided on the mixing barrel 2, and the spline shaft 5 is driven to rotate by a motor, so that the motor can drive the spline shaft 5 to rotate on the mixing barrel 2. The fixed axis rotates, through the spline sleeve 6 arranged on the spline shaft 5 and the conical grinding head 7 arranged on the spline sleeve 6, the spline sleeve 6 is movably sleeved on the spline shaft 5, so that the spline shaft 5 can drive the spline sleeve 6 and the conical grinding head 7 to rotate synchronously on the fixed axis. First, the sludge incineration ash and the mixed material required for making bricks are put into the inner wall of the mixing barrel 2 through the feed hopper 3, and the guide hopper 8 arranged on the mixing barrel 2 can enable the guide hopper 8 to guide the put mixed material to the end of the conical grinding sleeve 4. Through the lifting and lowering movement arranged on the spline shaft 5, the lifting mechanism can be lifted and lowered, so that the conical grinding head 7 can realize quantitative crushing and crushing of the mixed material on the top.

[0034] Embodiment 2:

[0035] On the basis of the first embodiment, further:

[0036] The lifting mechanism includes a cylindrical block 13 fixedly connected to the outer contour of the spline shaft 5 near the end, and an M-shaped groove 131 is opened on the cylindrical block 13. The inner walls of the M-shaped groove 131 on both sides are movably supported with a pull rod 14 for pulling the spline sleeve 6 for lifting and lowering, and a rotating ring 12 is rotatably connected to the outer contour of the end of the spline sleeve 6, and the ends of the pull rods 14 on both sides away from the cylindrical block 13 are respectively fixedly connected to the adjacent sides of the rotating ring 12.

[0037] The conical grinding sleeve 4 and the guide hopper 8 are symmetrically positioned on both sides and are fixedly connected with cylindrical tubes 9. The inner walls of the two cylindrical tubes 9 are connected to U-shaped tubes 11 for supporting the rotating ring 12 for lifting and movement. The opposite ends of the U-shaped tubes 11 on both sides are fixedly connected to the adjacent sides of the rotating ring 12 respectively. The bottom of the conical grinding head 7 is coaxially fixedly connected with a stirring rod 17 for stirring and mixing the sludge incineration ash.

[0038] When in use, the cylindrical tube 9 is fixedly supported on the conical grinding sleeve 4 and the guide hopper 8 by the cylindrical tube 9 arranged on the conical grinding sleeve 4 and the guide hopper 8, and the U-shaped tube 11 arranged on the cylindrical tube 9 is used to make the U-shaped tube 11 connected to the inner wall of the cylindrical tube 9 for lifting and moving. 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. The cylindrical block 13 arranged on the spline shaft 5 can make the spline shaft 5 drive the cylindrical block 13 to rotate synchronously on a fixed axis. The M-shaped groove 131 opened on the cylindrical block 13 and the pull rod 14 arranged on the M-shaped groove 131 can fix the pull rod 14 on the rotating ring 12, and the cylindrical block 13 rotates on a fixed axis, so that the pull rod 14 can pull the rotating ring 12 and the spline sleeve 6 to move synchronously up and down under the action of the M-shaped groove 131.

[0039] like Figure 2 and Figure 3 As shown, when the spline sleeve 6 moves in the downward direction, the gap between the conical grinding head 7 and the inner wall of the conical grinding sleeve 4 increases, so that the mixed material inside the guide hopper 8 falls on 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 in the upward direction, and the gap between the conical grinding head 7 and the inner wall of the conical grinding sleeve 4 is reduced, the spline shaft 5 drives the conical grinding head 7 to rotate, so that the conical grinding head 7 can crush the mixed material entering the conical grinding sleeve 4. As the spline sleeve 6 moves in the downward direction, the ground mixed material can fall to the bottom of the mixing barrel 2, and the stirring rod 17 arranged at the bottom of the conical grinding head 7 can feel the conical grinding head 7 driving the stirring rod 17 to rotate to stir the crushed mixed material at the bottom, thereby improving the mixing effect of sludge incineration ash and the mixed material required for making bricks, improving the application performance of sludge incineration ash in brick making, and ensuring the quality of bricks.

[0040] Embodiment three:

[0041] On the basis of the second embodiment, further:

[0042] L-shaped tubes 15 are penetrated and fixedly connected at symmetrical positions on both sides of the mixing barrel 2. The opposite ends of the L-shaped tubes 15 on both sides are respectively penetrated to the inner wall of the adjacent cylindrical tube 9 and fixedly connected. The ends of the two L-shaped tubes 15 away from the cylindrical tube 9 are penetrated and fixedly connected to a water storage barrel 16 for storing water. 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 uniform speed.

[0043] A water outlet 111 is provided on one side of the U-shaped tube 11 close to the L-shaped tube 15 to connect the L-shaped tube 15 with the inside of the U-shaped tube 11, and a sprinkler head 10 is fixedly connected to the bottom of the U-shaped tube 11 on both sides to evenly sprinkle water on the bottom of the mixing barrel 2.

[0044] When in use, the L-shaped tube 15 arranged on the mixing barrel 2 is used to fix and support the L-shaped tube 15 on the mixing barrel 2. Through the water storage barrel 16 arranged on the L-shaped tube 15, the inside of the water storage barrel 16 is first filled with water. Then the L-shaped tube 15 connects the water storage barrel 16 with the inside of the cylindrical tube 9, and through the water outlet hole 111 opened on the U-shaped tube 11, the water outlet hole 111 is adapted to the caliber of the L-shaped tube 15.

[0045] like Figure 2-Figure 4 As shown, when the spline sleeve 6 drives the conical grinding head 7 to move upward for rolling and grinding, and the U-shaped tube 11 moves upward under the action of the rotating ring 12, so that the water outlet 111 moves to fit the inner wall of the cylindrical tube 9, and the water outlet 111 is in a sealed state. When the spline sleeve 6 drives the conical grinding head 7 to move downward for feeding, and the U-shaped tube 11 drives the water outlet 111 to move downward and is 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 arranged on the U-shaped tube 11 enables the sprinkler head 10 to evenly sprinkle the water source on the mixed material at the bottom of the mixing barrel 2, accompanied by the stirring rod 17 stirring the bottom fertilizer, further improving the mixing effect of the water source and the material.

[0046] Embodiment 4:

[0047] On the basis of the third embodiment, further:

[0048] Extrusion blocks 18 are connected to the inner wall of the rectangular shell 1 at symmetrical positions at both ends for horizontal movement, and tooth plates 19 are fixedly connected to the bottom of the extrusion blocks 18 at both ends at symmetrical positions, and a movable groove 101 for the tooth plate 19 to move horizontally is provided at the bottom of the rectangular shell 1. A gear 20 is connected to the bottom of the rectangular shell 1 for pulling the extrusion blocks 18 at both ends to move toward or away from each other, and an extrusion mechanism is provided on the rectangular shell 1 for pulling the extrusion blocks 18 to extrude and shape the sludge incineration ash.

[0049] The extrusion mechanism includes a rectangular shell 1, at both sides of which symmetrical positions on one end are penetrated and connected to a fixed axis for rotation, and at the symmetrical positions on the ends of the cranks 21 on both sides are coaxially connected to connecting rods 22 for pulling the extrusion blocks 18 to extrude the sludge incineration ash, and the rectangular shell 1 is provided with rectangular through grooves 102 for the connecting rods 22 to move at both sides of the symmetrical positions near one end of the crank 21, and a worm 24 is penetrated and connected to the rectangular shell 1 for driving the crank 21 to rotate on a fixed axis, and a worm wheel 23 is coaxially fixedly connected to the crank 21 for meshing transmission with the worm 24, and pulleys 25 are fixedly connected to the corresponding positions of the worm 24 and the spline shaft 5 near the end, and the outer contours of the two pulleys 25 are provided with transmission belts 26 that drive the worm 24 and the pulleys 25 to rotate synchronously.

[0050] When in use, through the extrusion block 18 provided on the rectangular shell 1, the inner wall of the rectangular shell 1 on the extrusion block 18 is horizontally movable and connected, through the worm 24 provided on the rectangular shell 1, through the spline shaft 5 and the pulley 25 provided on the worm 24, and the transmission belt 26 provided on the pulley 25, along with the spline shaft 5, the fixed-axis rotation is performed, so that the transmission belt 26 can drive the worm 24 to synchronously rotate on the fixed axis under the action of the spline shaft 5, and the crank 21 provided on the rectangular shell 1 is connected to the rectangular shell 1 in a fixed-axis rotation, through the worm wheel 23 provided on the crank 21, and the worm wheel 23 and the worm 24 are meshed for transmission, so that the worm wheel 23 can drive under the action of the worm 24 The movable crank 21 rotates on the rectangular shell 1 on a fixed axis. Through the connecting rod 22 arranged on the crank 21, and the connecting rod 22 is rotatably supported on the extrusion block 18, the connecting rod 22 can pull the extrusion block 18 at the adjacent end to perform horizontal reciprocating movement under the rotation of the crank 21. Through the tooth plate 19 arranged on the extrusion block 18 and the movable groove 101 opened on the rectangular shell 1, the tooth plate 19 can be synchronously moved and connected in the horizontal direction inside the movable groove 101. Through the gear 20 arranged on the rectangular shell 1, the gear 20 can be meshed with the two tooth plates 19 for transmission, and then the tooth plate 19 drives the extrusion blocks 18 at both ends to reciprocate toward and away from each other under the action of the gear 20.

[0051] When the extrusion blocks 18 at both ends move away from each other to the limit distance, the extrusion block 18 near the end of the connecting rod 22 is out of contact with the mixing barrel 2. At this time, the mixed material at the bottom of the connecting rod 22 falls quantitatively to the inner wall of the rectangular shell 1 under the action of gravity. As the extrusion blocks 18 move toward each other, the extrusion blocks 18 can move toward each other and squeeze the mixed material inside the rectangular shell 1 into bricks. In this process, the top side of the extrusion block 18 near the end of the connecting rod 22 is sealed against the bottom of the mixing barrel 2 to prevent leakage of the mixed material at the bottom of the mixing barrel 2.

[0052] Embodiment five:

[0053] On the basis of the fourth embodiment, further:

[0054] A U-shaped frame 27 is penetrated and connected to the rectangular shell 1 at symmetrical positions on both sides and is horizontally movable, and a fixing rod 28 is fixedly connected to a position corresponding to the U-shaped frame 27 on one side of the rectangular shell 1, and a spring 29 is fixedly connected to the opposite surface of the fixing rod 28 and one side of the U-shaped frame 27 to guide the U-shaped frame 27 to reset and move, a movable block 30 is fixedly connected to the side of the top of the U-shaped frame 27 close to the fixing rod 28, and a limiting groove 103 for movably supporting the movable block 30 is provided at a position corresponding to the rectangular shell 1 and the U-shaped frame 27.

[0055] The extrusion block 18 at one end away from the worm gear 23 is fixedly connected with an inclined plate 31 that pushes the U-shaped frame 27 to move and fit the inner wall of the rectangular shell 1, and a supporting groove 104 is opened on the end of the rectangular shell 1 away from the worm gear 23 to movably support the inclined plate 31.

[0056] When in use, through the U-shaped frame 27 set on the rectangular shell 1, the U-shaped frame 27 is fitted with the inner wall of the rectangular shell 1, and the U-shaped frame 27 is horizontally connected to the rectangular shell 1. Through the fixed rod 28 set on the rectangular shell 1 and the spring 29 set on the fixed rod 28, the spring 29 can support the position of the fixed rod 28. Through the movable block 30 set on the U-shaped frame 27 and the limiting groove 103 opened on the rectangular shell 1, the limiting groove 103 can limit the moving direction of the movable block 30. Through the inclined panel 31 set on the extrusion block 18 and the supporting groove 104 opened on the rectangular shell 1, the inclined panel 31 is fixedly supported on the extrusion block 18, and the supporting groove 104 provides movably support for the inclined panel 31.

[0057] like Figure 7-Figure 8As shown, as the extrusion blocks 18 move toward each other, the inclined plate 31 first moves under the action of the extrusion block 18 to contact the movable block 30, so that the movable block 30 can pull the U-shaped frame 27 to move to the inner wall of the rectangular shell 1 under the action of the inclined surface of the inclined plate 31, and then the spring 29 is in an extrusion contraction state under the action of the U-shaped frame 27. At this time, the U-shaped frame 27 fits the inner wall of the rectangular shell 1, and the extrusion block 18 can push the mixed material to the inner wall of the U-shaped frame 27 for extrusion molding. Then, the formed bricks are located on the inner wall of the U-shaped frame 27. After the pressing block 18 completes the extrusion of the bricks, the extrusion block 18 moves away from each other, and the inclined plate 31 is out of contact with 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. As a result, the U-shaped frame 27 moves toward the side away from the fixed rod 28 under the elastic force of the spring 29. As the U-shaped frame 27 rotates and moves out of the inner wall of the rectangular shell 1, the bricks inside the U-shaped frame 27 can be unloaded under the action of gravity. The coordinated use of the above-mentioned structure realizes the automatic unloading of the formed bricks.

[0058] It is further realized that the existing device can grind and refine the ash in actual use, is easy to use, and is better than traditional products.

[0059] The standard parts used in this embodiment can be purchased directly from the market, and the non-standard structural components recorded in the specification and the drawings can also be directly processed according to the existing technical common sense. At the same time, the connection method of each component adopts the mature conventional means in the prior art, and the machinery, parts and equipment all adopt the conventional models in the prior art, so no specific description will be given here.

[0060] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
