Description

Technical Field

[0001] This invention relates to the field of technical waste recycling, specifically to a civil engineering waste treatment device. Background Technology

[0002] With the rapid advancement of urbanization and infrastructure construction, the amount of construction waste generated in the civil engineering field is experiencing explosive growth. Wood-based construction waste, a significant component, originates extensively from the loss and disposal of construction materials such as formwork, scaffolding, and decorative panels. This type of waste is extremely irregular in shape and size, not only occupying considerable space during transportation and leading to high costs, but also hindering efficient loading due to its loose physical properties, severely restricting transportation efficiency. Furthermore, the indiscriminate dumping of improperly treated wood waste not only occupies valuable land resources but also risks rotting and deteriorating due to prolonged exposure to the natural environment, breeding bacteria and insects, polluting surrounding soil, water sources, and air quality, and even posing a fire hazard.

[0003] In the recycling of wood-based construction waste, the irregular shape of the wood makes it difficult to transport and reuse. Typically, the wood waste is crushed into granules before transportation and recycling. However, in actual transportation and recycling, the sawdust is loose and bulky, taking up a lot of space, resulting in low transportation efficiency and inconvenience for recycling. Therefore, it is necessary to compact the sawdust into blocks to increase the loading capacity in a limited space and facilitate later recycling. When using existing briquetting devices to briquetize wood waste, the relatively dry surface of the sawdust results in weak adhesion between the sawdust particles when compressed into blocks. This makes the blocks prone to breakage under external vibration during transportation.

[0004] In view of the above, this application provides a civil engineering waste treatment device to solve the above problems. Summary of the Invention

[0018] The foregoing and other technical contents, features and effects of the present invention are described in conjunction with the appendix below. Figures 1 to 15 As will be clearly shown in the detailed description of the embodiments, the structural contents mentioned in the following embodiments are all with reference to the accompanying drawings. The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are only for illustration and explanation of the present invention and are not intended to limit the present invention.

[0019] Example 1, such as Figure 1-4 , Figures 9-15As shown, this invention discloses a civil engineering waste treatment device, comprising a frame 1, which consists of upper and lower cover plates and four support columns. A bearing plate 2 is fixedly installed on the lower part of the frame 1. A second semi-cylindrical cylinder 14 is fixedly installed inside a ring 31 fixedly installed at the center of the upper end face of the bearing plate 2. A third semi-cylindrical cylinder 15 is integrally formed on the outer arc surface of the bearing plate 2, and a first T-shaped groove 21 and multiple liquid outlet holes 141 are opened on the inner arc surface. A winding column 17 is symmetrically and rotatably installed on the upper end face of the bearing plate 2. The two winding columns 17 together wind up a filter screen 16. A first T-shaped slider 22 that slides with the first T-shaped groove 21 is fixedly installed on one side of the filter screen 16. A first motor 20 is fixedly sleeved on the lower end of the bearing plate 2 to drive the winding column 17 to rotate. A first hydraulic cylinder 4 and two second hydraulic cylinders 20 are fixedly installed on the upper end of the frame 1. Hydraulic cylinder 5, the movable plate 6 fixed at the output end of the second hydraulic cylinder 5 slides in cooperation with the four support columns of frame 1. The rotating ring 7 rotatably mounted at the lower end of the movable plate 6 is connected to the pressure plate 10 through the connecting column 9. The output end of the first hydraulic cylinder 4 passes through the movable plate 6 and the rotating ring 7. The output end of the first hydraulic cylinder 4 is rotatably mounted with a frustum 8. The frustum 8 has a through hole for the connecting column 9. The drive shaft 11 fixed at the lower end of the frustum 8 passes through the pressure plate 10 and has a first keyway 111. The heating rods 12 fixedly mounted in a circumferential array at the lower end of the frustum 8 also pass through the pressure plate 10. The first semi-cylindrical barrel 13 rotatably mounted on the outer arc surface of the frustum 8 can form a complete barrel with the second semi-cylindrical barrel 14. The contact surfaces of the first semi-cylindrical barrel 13 with the filter screen 16 and the bearing plate 2 are all provided with sealing strips to ensure the integrity of the formed barrel. The first semicircular cylinder 13 is sealed and can slide up and down relative to the second semicircular cylinder 14 under the action of the first hydraulic cylinder 4, and the first semicircular cylinder 13 is always in contact with the second semicircular cylinder 14. A boss 25 is integrally fixedly connected to the ring 31 on the upper end face of the bearing plate 2 near the second semicircular cylinder 14. A rotating column 233 is rotatably installed at the center of the bearing plate 2. A second keyway 234 is opened on the lower end face of the rotating column 233. A first semicircle 23 is fixedly installed on the upper end face of the rotating column 233. An annular slide 231 is opened on the lower end face of the first semicircle 23. The boss 25 slides in cooperation with the annular slide 231 at the lower end of the first semicircle 23. A second semicircle 24 is provided on the upper end face of the bearing plate 2. The second semicircle 24 is connected to the second T-shaped groove 23 of the first semicircle 23 through the second T-shaped slider 242. 2. A sliding fit is used, where two semicircles can form a complete circle. A sealing strip is provided on the outer arc surface of the first semicircle 23, and sealing strips are also provided on the outer arc surface of the second semicircle 24 and the surface in contact with the first semicircle 23. This ensures a seal between the complete circle formed by the two semicircles and the complete circular barrel formed by the two semicircles, preventing material leakage. The rotating column 233 has a through hole for the drive shaft 11 to pass through. The drive shaft 11 and the rotating column 233 are in a sealed sliding fit to prevent material leakage. A limit ring 26 is slidably installed at the center of the lower end face of the bearing plate 2, and the bearing plate 2 and the limit ring 26 are elastically connected by a spring. A drive block 27 is provided on the lower end face of the bearing plate 2, which is rotatably installed with the limit ring 26. The output end of the second motor 28 is in a sliding fit with the keyway on the lower end face of the drive block 27.The upper surface of the drive block 27 has a first flat key 271 that mates with the keyway of the second keyway 234 and a second flat key 272 that mates with the keyway of the first keyway 111. The first flat key 271 is located above the second flat key 272.

[0020] Specifically, the second hydraulic cylinder 5 and the first hydraulic cylinder 4 are activated, and their output ends push the moving plate 6 and the frustum 8 to slide downwards along the frame 1, causing the pressure plate 10 and the first semi-circular barrel 13 to descend synchronously, so that the first semi-circular barrel 13 and the second semi-circular barrel 14 are completely merged. The first motor 20 is activated, driving the winding column 17 to rotate, so that the filter screen 16 slides along the first T-shaped groove 21 through the first T-shaped slider 22 until the mesh of the filter screen 16 does not overlap with the liquid outlet 141 of the second semi-circular barrel 14. Figure 1-3As shown, at this time, the drive shaft 11 at the lower end of the frustum 8 pushes the drive block 27 downward, stretching the spring between the limiting ring 26 and the bearing plate 2, causing the first flat key 271 inside the drive block 27 to disengage from the second keyway 234 under the rotating column 233. The second flat key 272 inside the drive block 27 engages with the first keyway 111 of the drive shaft 11. After adding wood chips and excess water into the cylinder formed by the first semi-cylindrical cylinder 13 and the second semi-cylindrical cylinder 14, the second motor 28 is started. The output end of the second motor 28 slides into the keyway on the lower end face of the drive block 27, and the second motor 28 drives the drive block 27 to rotate. The second flat key 272 inside the drive block 27 engages with the first keyway 111 of the drive shaft 11, and the drive block 27 drives the drive shaft 11 to rotate. Shaft 11 is fixedly fitted to frustum 8. Drive shaft 11 drives frustum 8 to rotate. Because frustum 8 is fixedly fitted to heating rod 12 and slidably fitted to connecting column 9, and connecting column 9 is fixedly installed to pressure plate 10 and rotating ring 7, frustum 8 drives heating rod 12, connecting column 9, pressure plate 10 and rotating ring 7 to rotate, stirring the material in the barrel composed of first semi-cylindrical barrel 13 and second semi-cylindrical barrel 14. After the wood chips and water are fully mixed, second motor 28 stops rotating, and first motor 20 is started to drive winding column 17 to rotate, so that filter screen 16 slides along first T-shaped groove 21 through first T-shaped slider 22. At this time, the mesh of filter screen 16 continuously overlaps with the liquid outlet 141 of second semi-cylindrical barrel 14. At the same time, second hydraulic cylinder 5 is started, and its output end pushes the movement. Plate 6 drives rotating ring 7 to move downwards, and rotating ring 7 drives pressure plate 10 to move downwards via connecting column 9, compacting the wood chips. Moisture in the wood chips is discharged through the mesh of filter screen 16 and the liquid outlet 141 of the second semi-circular barrel 14. Simultaneously, heating rod 12 is activated to heat and solidify the compacted waste, improving the molding effect. After solidification, first hydraulic cylinder 4 and second hydraulic cylinder 5 are activated, moving plate 6 and frustum 8 to slide upwards along frame 1, causing pressure plate 10 and first semi-circular barrel 13 to rise synchronously, partially separating the first semi-circular barrel 13 from the second semi-circular barrel 14. At this time, the first keyway 111 on drive shaft 11 disengages from the second flat key 272 in drive block 27, and drive shaft 11 no longer applies downward pressure to drive block 27. Drive block 27 is reset under the action of the spring between limit ring 26 and bearing plate 2. The first flat key 271 inside drive block 27 engages with the second keyway 234 under rotating column 233, starting the second motor 28. Its output drives drive block 27 to rotate. Drive block 27 drives rotating column 233 to rotate 180 degrees. Rotating column 233 drives first semicircle 23 and second semicircle 24 to rotate 180 degrees. When rotating, second semicircle 24 contacts boss 25. Under the action of boss 25, second semicircle 24 slides in the second T-shaped groove 232 of first semicircle 23 through second T-shaped slider 242. Second semicircle 24 rises relative to first semicircle 23.like, Figure 4 As shown, this allows the extruded material to separate from the first semicircle 23, making it easier to remove the material.

[0021] Example 2, as Figure 7-10 As shown, the present invention provides a civil engineering waste treatment device, including multiple sets of cleaning brushes 151 fixedly installed at the contact surface between the third semi-circular barrel 15 and the filter screen 16, multiple sets of scrapers 152 fixedly installed at the contact surface between the third semi-circular barrel 15 and the filter screen 16, and a collection box 153 provided on the upper end surface of the bearing plate 2.

[0022] Specifically, during the extrusion process, the filter screen 16 separates the wood chips from the treatment liquid. Wood chips easily adhere to the surface of the filter screen 16, clogging the mesh. During extrusion, the first motor 20 is started, driving the winding column 17 to rotate, causing the filter screen 16 to slide along the first T-shaped groove 21 via the first T-shaped slider 22. At this time, the mesh of the filter screen 16 continuously overlaps with the liquid outlet 141 of the second semi-circular barrel 14. During the movement, the filter screen 16 comes into contact with the cleaning brush 151 and scraper 152 on the surface of the third semi-circular barrel 15. The cleaning brush 151 brushes away the blockages in the mesh of the filter screen 16, and the scraper 152 scrapes away the blockages to prevent them from sticking to the filter screen 16. The blockages scraped away by the scraper 152 fall into the collection box 153, realizing the self-cleaning of the filter screen 16 and avoiding clogging that could affect subsequent use.

[0023] Example 3, as Figure 1-2 As shown, the present invention provides a civil engineering waste treatment device, which includes a raw material box 3 on one side of a frame 1, a centrifugal fan 29 fixedly installed on the lower end face of a bearing plate 2 and fixedly installed with the frame 1, the exhaust end of the centrifugal fan 29 extending into the raw material box 3, and a discharge pipe 30 fixedly installed at the exhaust end of the centrifugal fan 29, the discharge pipe 30 penetrating the second semi-circular barrel 14.

[0024] Specifically, when wood chips are added to the cylinder composed of the first semi-circular cylinder 13 and the second semi-circular cylinder 14, the centrifugal fan 29 is started. The centrifugal fan 29 generates negative pressure, which sucks in the wood chips in the raw material box 3 and transports them through the discharge pipe 30 to the closed first semi-circular cylinder 13 and the second semi-circular cylinder 14. This achieves efficient and uniform feeding of wood chips, avoids dust pollution and uneven feeding caused by manual feeding, and is suitable for large-scale operation needs.

[0025] Example 4, as Figure 3 and Figure 5As shown, the present invention provides a civil engineering waste treatment device, including a solution tank 18 fixedly installed on the lower end face of a support plate 2 and a frame 1. An injection pump 181 is fixedly installed inside the solution tank 18. An injection pipe 19 is fixedly installed on the injection pump 181, penetrating a second semi-circular barrel 14. A return port 182 penetrating the support plate 2 and the solution tank 18 is opened between the third semi-circular barrel 15 and the second semi-circular barrel 14. A nozzle 32 is fixedly installed at the end of the injection pipe 19 that penetrates the second semi-circular barrel 14.

[0026] Specifically, when water is added to the cylinder composed of the first semi-circular barrel 13 and the second semi-circular barrel 14, the injection pump 181 is started, and the liquid in the solution tank 18 is transported to the nozzle 32 through the injection pipe 19. The nozzle 32 sprays water into the cylinder composed of the first semi-circular barrel 13 and the second semi-circular barrel 14, so that the water comes into contact with the wood chips. When the wood chips are squeezed, the liquid in the first semi-circular barrel 13 and the second semi-circular barrel 14 is discharged through the mesh of the filter screen 16 and the liquid outlet 141 of the second semi-circular barrel 14, flows into the cavity between the third semi-circular barrel 15 and the second semi-circular barrel 14, and then flows back to the solution tank 18 through the return port 182, realizing the recycling of the treatment liquid, saving resources and improving the efficiency of pollutant treatment.

[0027] Working principle: In the preparation stage, the second hydraulic cylinder 5 and the first hydraulic cylinder 4 are started. Their output ends push the moving plate 6, the frustum 8, the pressure plate 10, and the first semi-cylindrical barrel 13 to slide downwards along the frame 1, so that the first semi-cylindrical barrel 13 and the second semi-cylindrical barrel 14 on the support plate 2 are precisely closed to form a complete barrel. The first motor 20 is started, and its output end drives the winding column 17 to rotate, which drives the filter screen 16 to slide along the first T-shaped groove 21 on the inner arc surface of the second semi-cylindrical barrel 14 through the first T-shaped slider 22 on one side until the mesh of the filter screen 16 is completely misaligned with the liquid outlet hole 141 opened on the arc surface of the second semi-cylindrical barrel 14, preventing the solution from flowing out directly after entering, thus completing the preparation work before feeding. The centrifugal fan 29 is started, and its exhaust end extends into the raw material box 3 to generate negative pressure, which pushes the box... Civil engineering waste, such as wood chips, is drawn into a closed cylinder through the discharge pipe 30 for uniform feeding. Simultaneously, the injection pump 181 in the solution tank 18 is activated, and water is delivered through the injection pipe 19 to the nozzle 32 penetrating the second semi-cylindrical 14. The water is then evenly sprayed onto the waste. At this time, the drive shaft 11 at the lower end of the truncated cone 8 pushes the drive block 27 downwards, stretching the spring between the limiting ring 26 and the bearing plate 2. This causes the second flat key 272 inside the drive block 27 to form a keyway fit with the first keyway 111 at the lower end of the drive shaft 11. The second motor 28 is then activated, its output end slidingly engaging with the keyway on the lower end face of the drive block 27, driving the drive block 27, drive shaft 11, and truncated cone 8 to rotate synchronously. The truncated cone 8 drives the heating rods 12 in the lower circumferential array and penetrates the truncated cone 8. The connecting column 9 and the pressure plate 10 rotate to fully mix the waste and treatment liquid in the barrel. After mixing, the second motor 28 stops working, and the first motor 20 is restarted to adjust the rotation direction of the winding column 17, so that the filter screen 16 slides in the opposite direction along the first T-groove 21. The mesh of the filter screen 16 gradually overlaps with the liquid outlet 141 of the second semi-cylinder 14. The second hydraulic cylinder 5 is activated, and its output end pushes the pressure plate 10 downward to apply pressure to the mixed waste to achieve dehydration. The separated water flows into the cavity between the second semi-cylinder 14 and the third semi-cylinder 15 through the mesh of the filter screen 16 and the liquid outlet 141. During the movement of the filter screen 16, the cleaning brush 151 fixed on the contact surface between the third semi-cylinder 15 and the filter screen 16 brushes away the water inside the mesh of the filter screen 16. The filter screen 16 is blocked by scraper 152, which removes waste particles adhering to its surface. The detached blockages and particles fall into the collection box 153 on the upper surface of the support plate 2, achieving self-cleaning of the filter screen 16. During the dehydration process, the heating rod 12 at the lower end of the truncated cone 8 is activated simultaneously to heat and solidify the squeezed waste material, improving the structural strength and stability of the formed waste material and ensuring the subsequent recycling effect. The treatment liquid generated during dehydration is collected in the cavity between the second semi-cylinder 14 and the third semi-cylinder 15, and flows back to the solution tank 18 through the return port 182 that runs through the support plate 2 and the solution tank 18. It is then pumped again by the injection pump 181 to the injection pipe 19, realizing the recycling of the treatment liquid. After solidification is completed, the first hydraulic cylinder 4 and the second hydraulic cylinder 5 are activated.The moving plate 6, the frustum 8, the pressure plate 10, and the first semi-circular cylinder 13 slide upwards along the frame 1 to reset. The first semi-circular cylinder 13 and the second semi-circular cylinder 14 partially separate. At this time, the first keyway 111 on the drive shaft 11 disengages from the second flat key 272 of the drive block 27. The drive block 27 resets under the spring force, and its upper first flat key 271 forms a keyway fit with the lower second keyway 234 of the rotating column 233. The second motor 28 is started, driving the drive block 27, the rotating column 233, and the upper first and second semi-circles 23 and 24 to rotate synchronously by 180°. During the rotation, the protrusion 241 at the lower end of the second semi-circle 24 contacts the boss 25 on the bearing plate 2. Guided by the boss 25, the second semi-circle 24 slides upwards along the second T-shaped groove 232 on the straight surface of the first semi-circle 23 via the second T-shaped slider 242 on one side, causing the molding waste to separate from the first and second semi-circles 23 and 24, facilitating demolding and removal of the molding waste.
