Description

Technical Field

[0001] The invention relates to the technical field of solid waste sediment preparation, and specifically proposes a process for preparing building blocks by utilizing solid waste sediment. Background Art

[0002] Solid waste sediment usually refers to waste sedimentation in liquid treatment processes, sludge sedimentation in sewage treatment, suspended matter or sediment in rivers, lakes or other waters, and waste particles generated in industrial processes. In order to avoid waste, these solid waste sediments are generally recycled and used to prepare building blocks. The preparation process of building blocks generally includes the following steps:

[0003] Solid waste screening: remove impurities and parts that are not suitable as raw materials → Solid waste crushing: make its particles of moderate size for subsequent processing and use → Sand settling treatment: use sand settling technology to mix solid waste with water in a container, suspend the solid waste in the water, and then let it stand for a certain period of time. With the help of gravity, the heavier solid waste will settle at the bottom of the container to form mud → Filtration and drying: to reduce the moisture content → The dried solid waste residue is heated and mixed with an appropriate amount of cement at a certain temperature to obtain casting slurry → Pressing: inject the mixed and heated casting slurry into the pressing equipment and press it into building blocks of the required shape and size.

[0004] However, the following problems still exist in the process of preparing building blocks: 1. When preparing building blocks, the traditional method is generally to directly press them into building blocks using molds. After pressing and forming, the pressed building blocks need to be moved and stacked on another device for the next drying operation. In this process, since the building blocks just after pressing are not fully formed, they are very likely to be damaged, which will have a certain impact on the molding quality of the building blocks.

[0005] 2. In the process of preparing building blocks, the traditional method is to shake the mold to vibrate and exhaust the casting slurry in the mold. The casting slurry in the mold cannot be effectively exhausted, resulting in poor exhaust effect, reducing the strength of the casting slurry, and further affecting the quality of the building blocks, thereby affecting the service life of the building blocks.

[0006] Therefore, in order to avoid affecting the molding quality and service life of the building blocks, the present invention provides a process for preparing building blocks by utilizing solid waste sedimentation. Summary of the invention

[0012] S4. Filtration and drying: The precipitated mud is passed through a filter or centrifuge to remove excess water, and the obtained solid residue is dried.

[0041] See also Figure 1 A process for preparing building blocks using solid waste sedimentation, the process for preparing building blocks using solid waste sedimentation specifically comprises the following steps:

[0042] S1. Solid waste screening: Select concrete waste and construction waste as solid waste raw materials, and screen the solid waste raw materials.

[0043] S2. Solid waste crushing: crush the screened solid waste raw materials to a moderate particle size.

[0044] S3. Sedimentation treatment: The solid waste is mixed with water in a container by using sedimentation technology, so that the solid waste is suspended in the water, and then left to stand for a certain period of time. With the help of gravity, the heavier solid waste is settled to the bottom of the container to form mud.

[0045] S4. Filtration and drying: The precipitated mud is passed through a filter or centrifuge to remove excess water, and the obtained solid residue is dried.

[0046] S5. Mixing and heating: The dried solid waste residue is heated and mixed with an appropriate amount of cement at a certain temperature to obtain a pouring slurry.

[0047] S6, pressing operation: the casting slurry obtained after mixing and heating is injected into the fixing mechanism 2. After the injection is completed, it is pressed into a building block of a desired shape and size by the provided pressing mechanism 3. Finally, the pressing mechanism 3 is cleaned by the provided cleaning mechanism 4.

[0048] See also Figure 2 The process of preparing building blocks using solid waste sediment using the above steps S1-S6 also specifically involves a device for preparing building blocks using solid waste sediment, including a fixed base 1, two groups of fixing mechanisms 2 for pouring slurry are symmetrically arranged on the top of the fixed base 1, a pressing mechanism 3 for pressing building blocks is arranged between the two groups of fixing mechanisms 2 on the top of the fixed base 1, and a detachable cleaning mechanism 4 is arranged on the right end surface of the workbench.

[0049] See also Figure 3 and Figure 5 The fixing mechanism 2 on the front side includes four support rods 21 fixedly installed on the top of the front side of the fixed base 1. The tops of the four support rods 21 are in a conical structure with a small diameter section upward. The bottom of the structural plate 22 is provided with circular grooves matching the support rods 21 near the four corners. A plurality of detachable square molds 23 in a return-shaped mechanism are evenly arranged on the top of the structural plate 22 from left to right. A limiting component 24 is symmetrically arranged on the front and back of the structural plate 22 in the square mold 23.

[0050] In the original state, the structural plate 22 is first placed on the support rod 21. The support rod 21 with a tapered structure with a small diameter section at the top can leave a certain amount of space margin and can also play a role of guiding and limiting, so as to facilitate the rapid installation and disassembly of the structural plate 22. After the structural plate 22 is installed, the multiple square molds 23 are quickly assembled with the structural plate 22. When the assembly is completed, the pouring slurry obtained after mixing and heating is injected into the square mold 23 on the structural plate 22 on the front side. After the injection, it is quickly pressed and formed by the set pressing mechanism 3. During the pressing process, the pouring slurry in the square mold 23 can be pressed by the cooperation of the set pressing mechanism 3 and the set limiting component 24. The set limiting component 24 can prevent the pouring slurry from falling before being pressed after injection. The multiple square molds 23 are detachably connected to the structural plate 22. After the building blocks are formed, the multiple square molds 23 can be quickly unloaded.

[0051] See also Figure 2 , Figure 3 and Figure 4 The pressing mechanism 3 includes a displacement groove opened on the top of the fixed base 1, a moving block 31 is slidably arranged in the displacement groove, a threaded rod 32 is rotatably arranged in the displacement groove and connected to the moving block 31 through a thread, a No. 1 intermittent motor which can rotate forward and reverse and is fixedly connected to one end of the threaded rod 32 is fixedly installed on the left end surface of the fixed base 1 through a motor seat, a pressing component 34 is arranged on the top of the moving block 31 through a fixing component 33, and a moving component 35 is also arranged on the pressing component 34.

[0052] After the square mold 23 on the structural plate 22 is injected with the casting slurry obtained after mixed heating, the intermittent motor No. 1 that rotates forward and reverse can be started to rotate forward, and the intermittent motor No. 1 drives the threaded rod 32 to rotate. At this time, under the limit of the displacement groove, the threaded rod 32 causes the moving block 31 to move in the displacement groove, and then the fixed component 33 on the moving block 31 drives the pressing component 34 to move, so that the pressing component 34 moves to the front side of the square mold 23 with the cast slurry directly above, at this time, the fixed component 33 and the moving component 35 are set to enable the pressing component 34 to press the casting slurry in the square mold 23. During the pressing process, the moving component 35 causes the pressing component 34 to vibrate and press downward, so that the air and bubbles in the casting slurry in the square mold 23 can be discharged, so that the slurry presents a tighter structure, enhances the strength of the casting slurry, and thereby improves the quality of the cast building blocks.

[0053] See also Figure 4The fixed component 33 includes a No. 2 intermittent motor fixedly installed on the top of the moving block 31, an inverted L-shaped plate 331 is fixedly installed on the top of the No. 2 intermittent motor, a square plate 332 is fixedly installed on the front end surface of the horizontal section of the inverted L-shaped plate 331, a pressing plate 333 is fixedly installed on the bottom of the square plate 332 through an electric telescopic rod, and the pressing plate 333 and the square plate 332 are fixedly connected by front-to-back symmetrical spring rods 334.

[0054] When the pressing assembly 34 moves to the top of the square mold 23 with the slurry poured on the front side, the electric telescopic rod is started, and the electric telescopic rod makes the pressing plate 333 drive the pressing assembly 34 to press the poured slurry in the square mold 23. When the pressing is completed, the second intermittent motor installed on the moving block 31 makes the inverted L-shaped plate 331 drive the square plate 332 to rotate 180 degrees, so that the pressing plate 333 on the square plate 332 drives the pressing assembly 34 to rotate 180 degrees, so that the pressing assembly 34 is located above the square mold 23 on the rear structural plate 22. At this time, the electric telescopic rod is started again, and the electric telescopic rod is retracted. The rod enables the pressing plate 333 to drive the pressing assembly 34 to press the casting slurry in the square mold 23. While pressing the casting slurry in the square mold 23 on the rear structural plate 22, the front structural plate 22 can be directly unloaded quickly, that is, multiple groups of pressed building blocks on the front structural plate 22 are unloaded. This pressing method does not require the pressed building blocks to be moved and stacked on another device for the next drying operation, thereby avoiding the situation where the incompletely formed building building blocks are easily damaged during the movement, thereby greatly improving the molding quality of the building building blocks.

[0055] Continue reading Figure 4 The pressing assembly 34 includes a rectangular plate 341 symmetrically fixedly installed on the pressing plate 333, a conical plate 342 is fixedly installed at the bottom of the rectangular plate 341, the top of the rectangular plate 341 is located above the pressing plate 333 and is provided with a rectangular groove, a rubber tower sleeve 343 is fixedly installed in the rectangular groove, a fixing rod 344 is fixedly installed on the rubber tower sleeve 343, a movable plate 345 is fixedly installed at one end of the fixing rod 344 located in the rectangular groove, and a round head plate 346 is fixedly installed at the top of the fixing rod 344 near the right side.

[0056] See also Figure 2 and Figure 3 The limiting component 24 includes a circular through groove opened on the structural plate 22, and the four right-angled sides of the circular through groove are hinged with a triangular plate 241 through a pin shaft. The bottom of the structural plate 22 is located at the position of the circular through groove and a fixed frame 242 with a circular structure is fixedly installed. The four right-angled sides of the fixed frame 242 and the triangular plate 241 are connected by a torsion spring 243.

[0057] When the electric telescopic rod is started to move the pressing plate 333 downward, the pressing plate 333 causes the rectangular plate 341 to drive the conical plate 342 to move downward, and the bottom sharp corner of the conical plate 342 first contacts the middle position between the four triangular plates 241. In the process of the rectangular plate 341 driving the conical plate 342 to continue to move downward, the conical plate 342 causes the triangular plate 241 to squeeze the torsion spring 243. The bottom of the conical plate 342 is set to be pointed, which can facilitate rapid entry into the casting slurry in the square mold 23, facilitate rapid pressing of the building blocks, and improve the work efficiency when pressing the building blocks. After the casting slurry in the square mold 23 is pressed, the electric telescopic rod causes the rectangular plate 341 to drive the conical plate 342 to return to its original position. At this time, under the action of the torsion spring 243, multiple triangular plates 241 also return to their original positions.

[0058] See also Figure 8 The moving component 35 includes a vertical plate 351 fixedly installed at a position near the right side of the top of the pressing plate 333. A sliding groove is provided at one end of the vertical plate 351 near the round head plate 346. An extension plate 352 is provided in the sliding groove for sliding through an electric slider. A connecting plate 353 is fixedly installed at one end of the extension plate 352 near the round head plate 346. Two groups of arc-shaped protrusions 354 that match the round head plate 346 are fixedly installed on the connecting plate 353.

[0059] When the electric telescopic rod causes the rectangular plate 341 to drive the conical plate 342 to move downward to press the casting slurry in the square mold 23, the electric slider is started, and the electric slider causes the extended plate 352 to drive the connecting plate 353 to move back and forth, so that the connecting plate 353 drives the arc-shaped protrusion 354 to move back and forth, and in the process of the arc-shaped protrusion 354 moving back and forth, the round head plate 346 is pushed to move left and right. At this time, under the reset of the rubber tower sleeve 343, the round head plate 346 drives the fixed rod 344 to move back and forth, and the fixed rod 344 causes the moving plate 345 to knock the rectangular plate 341 to vibrate, and the rectangular plate 341 drives the conical plate 342 to vibrate while moving downward, which can discharge the air and bubbles in the casting slurry in the square mold 23, thereby making the slurry present a tighter structure and enhancing the strength of the casting slurry.

[0060] See also Figure 2 The left end face of the fixed base 1 is symmetrically provided with movable grooves in the front and rear, and a debris box 11 for holding excess pouring slurry is slidably arranged in the movable groove. The debris box 11 is located directly below the structural plate 22.

[0061] By means of the slidably connected debris box 11 arranged just below the structural plate 22, when the conical plate 342 pushes the multiple triangular plates 241 to open, some excess pouring slurry will fall into the debris box 11 and be collected by the debris box 11, which can be recycled again, without causing a certain impact on the working environment and a certain amount of waste.

[0062] See also Figure 6 and Figure 7 The cleaning mechanism 4 includes a detachable fixed plate 41 arranged on the right side of the fixed base 1, a rectangular frame 42 with an opening upward is fixedly installed on the top of the fixed plate 41, a horizontal plate 43 is fixedly installed near the top of the rectangular frame 42, a rectangular through groove with a round-shaped structure is symmetrically opened on the top of the horizontal plate 43, two groups of round-shaped frames 44 are symmetrically and detachably arranged in the rectangular through groove, a cleaning brush 45 is fixedly installed along the circumferential direction on the inner end surface of the round-shaped frame 44 located on the upper side, and the lengths of the cleaning brushes 45 are different, and a round-shaped scraper 46 is fixedly installed along the circumferential direction on the inner end surface of the round-shaped frame 44 located on the lower side, and rectangular leakage grooves are opened on the round-shaped scraper 46 near the four right-angled sides.

[0063] After the building blocks on the front structural plate 22 are pressed, the fixed plate 41 is installed to the right side of the fixed base 1. At this time, the moving block 31 is located at the rightmost side of the displacement slot. At this time, the No. 2 intermittent motor is started to rotate 90 degrees, and the No. 2 intermittent motor drives the square plate 332 to rotate 90 degrees, so that the pressing plate 333 on the square plate 332 drives the pressing assembly 34 to rotate 90 degrees, so that the pressing assembly 34 is located directly above the rectangular frame 42. At this time, the electric telescopic rod is started to reciprocate up and down. During the movement, the rectangular plate 341 is moved on the horizontal plate The rectangular through groove 43 on the rectangular plate 341 reciprocates up and down. During the movement, the residual pouring slurry on the rectangular plate 341 can be scraped off by the provided circular scraper 46, and the residual pouring slurry on the rectangular plate 341 can be cleaned by the provided cleaning brush 45, so as to avoid the pouring slurry remaining on the rectangular plate 341, which will further affect the next group of building blocks that need to be pressed. The rectangular leakage trough opened on the circular scraper 46 can facilitate the pouring slurry after cleaning to be discharged into the rectangular frame 42 through the rectangular leakage trough.

[0064] Specific work:

[0065] The first step is to place the structural plate 22 on the support rod 21. After the structural plate 22 is installed, multiple square molds 23 are quickly assembled between the structural plate 22. When the assembly is completed, the casting slurry obtained after mixing and heating is injected into the square mold 23 on the structural plate 22 on the front side.

[0066] The second step is to start the forward and reverse rotating intermittent motor No. 1 to rotate forward, and the intermittent motor No. 1 drives the threaded rod 32 to rotate. At this time, under the limit of the displacement groove, the threaded rod 32 causes the moving block 31 to move in the displacement groove, and then the fixed component 33 on the moving block 31 drives the pressing component 34 to move, so that the pressing component 34 moves to the front side of the square mold 23 where the slurry is poured. At this time, the electric telescopic rod is started, and the electric telescopic rod causes the pressing plate 333 to drive the pressing component 34 to press the poured slurry in the square mold 23. During the pressing process, the electric slider is started, and the electric slider causes the extending plate 352 to drive The connecting plate 353 reciprocates back and forth, so that the connecting plate 353 drives the arc-shaped protrusion 354 to reciprocate back and forth, and in the process of the arc-shaped protrusion 354 reciprocating back and forth, the round head plate 346 is pushed to move left and right. At this time, under the reset of the rubber tower sleeve 343, the round head plate 346 drives the fixed rod 344 to reciprocate left and right, and the fixed rod 344 causes the movable plate 345 to knock the rectangular plate 341 to vibrate. The rectangular plate 341 drives the conical plate 342 to vibrate and move downward at the same time, which can discharge the air and bubbles in the pouring slurry in the square mold 23, so that the slurry presents a tighter structure and enhances the strength of the pouring slurry.

[0067] The third step is that after the pressing of the building blocks on the front structural plate 22 is completed, the fixed plate 41 is installed to the right side of the fixed base 1. At this time, the movable block 31 is located at the rightmost side of the displacement slot. At this time, the No. 2 intermittent motor is started to rotate 90 degrees. The No. 2 intermittent motor drives the square plate 332 to rotate 90 degrees, so that the pressing assembly 34 is located directly above the rectangular frame 42. At this time, the electric telescopic rod is started to move back and forth up and down. During the movement, the rectangular plate 341 moves back and forth up and down in the rectangular through groove on the horizontal plate 43. During the movement, the residual casting slurry on the rectangular plate 341 can be scraped and cleaned by the provided circular scraper 46 and the cleaning brush 45, so as to avoid the casting slurry remaining on the rectangular plate 341, which will affect the next group of building blocks to be pressed.
