Description

Technical Field

[0001] This invention relates to the field of brick-making technology, specifically to equipment for mixing, crushing, and powdering construction waste and slag to make bricks. Background Technology

[0002] Construction waste refers to the slag, waste soil, waste materials, silt, and other waste generated during the construction, laying, demolition, and repair of various buildings, structures, and pipelines by construction units or individuals. Slag generally refers to coal ash, which is a type of industrial solid waste. If slag and construction waste are left unattended for a long time, it will have a detrimental impact on environmental sanitation, living conditions, and land quality assessment. Recycling and crushing construction waste and slag to make bricks allows for resource reuse. In existing technology, patent publication number CN215790586U discloses a method involving... A novel brick-making device includes a conveying mechanism, an oil spraying mechanism on one side of the starting end of the conveying mechanism, and a forming mechanism in the middle section of the conveying mechanism. A base plate is provided on the conveying mechanism, and a laser detector is provided on the top of the forming mechanism. This invention effectively prevents the brick blank from sticking to the base plate, thus preventing damage to the surface of the brick blank when it separates from the base plate. However, when the device extrudes the brick after extrusion and unloading, the bricks are easily squeezed and adhered to the inside of the mold, unable to fall onto the base plate. At the same time, the raw material for the mold is supplied through the filling hopper during the brick-making process, and the raw material inside the mold needs to be manually scraped and leveled afterward, which is inconvenient. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to overcome the existing defects and provide a device for mixing, crushing and powdering construction waste and slag to make bricks. When the device supplies brick-making raw materials to the mold, it can automatically and elastically scrape the raw materials to reduce the intensity of manual labor. At the same time, the device can squeeze the extruded bricks out of the mold through the spring force to avoid the phenomenon of extrusion and adhesion between the two. Furthermore, the crushing part of the device can be adjusted for crushing gap, which has a wide range of applications and can effectively solve the problems in the background technology.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a crushing and powdering equipment for construction waste and slag, comprising a crushing shell, a brick-making frame, and a crushing mechanism;

[0005] Crushing shell: Its top wall is provided with a feed hopper, and its conical bottom wall is provided with a discharge pipe;

[0006] Brick-making frame: A lower pressure seat is provided on the right end of its top wall via a liquid rod 1. The lower surface of the lower pressure seat is provided with evenly distributed rectangular shells. Sliding shells are slidably connected inside the rectangular shells. A mold is provided between the front and rear ends of the right side of the top wall of the brick-making frame via a liquid rod 2. A connecting seat is provided on the left side of the top wall of the brick-making frame via a liquid rod 3. A packing shell is provided on the right side of the connecting seat via a liquid rod 4. The packing shell and the sliding shell are installed in conjunction with the mold.

[0007] Crushing mechanism: Located inside the crushing shell, this device can automatically and elastically scrape the powdered brick-making raw materials when supplying them to the mold, reducing the intensity of manual labor. At the same time, the device can squeeze the extruded bricks out of the mold through the spring force, avoiding the phenomenon of extrusion and adhesion between the two. In addition, the crushing part of the device can adjust the crushing gap, making it widely applicable.

[0008] Furthermore, it also includes a microcontroller and a chain-plate electric conveyor belt. The microcontroller is located outside the brick-making frame, and the chain-plate electric conveyor belt is located at the lower end of the brick-making frame. The input end of the microcontroller is electrically connected to an external power source, and the output end of the microcontroller is electrically connected to the input end of the chain-plate electric conveyor belt to control the electrical components and transport the pallet.

[0009] Furthermore, the crushing mechanism includes a cross, a rotating shaft, a lower crushing disc, an upper crushing disc, a drive shaft, bevel gears, and a motor. The cross is located inside the crushing shell. The upper side of the cross is rotatably connected to the rotating shaft via a bearing. The upper end of the rotating shaft is slidably connected to the lower crushing disc. The top wall of the crushing shell is provided with an upper crushing disc, which is installed in conjunction with the lower crushing disc. The right wall of the crushing shell is rotatably connected to the drive shaft via a bearing. Both the left end of the drive shaft and the lower end of the rotating shaft are provided with bevel gears, which mesh together. The input end of the motor located on the right side of the crushing shell is electrically connected to the output end of a microcontroller. The output shaft of the motor is fixedly connected to the right end of the drive shaft, thus crushing construction waste and slag.

[0010] Furthermore, the crushing mechanism also includes an electric rod and an annular groove. The electric rod is disposed on the upper surface of the cross, and its input end is electrically connected to the output end of the microcontroller. A circular seat is slidably connected in the annular groove opened on the lower side of the lower crushing disc. The telescopic end of the electric rod is fixedly connected to the lower side of the circular seat to adjust the crushing gap of the device.

[0011] Furthermore, a guide groove is provided on the outer side of the rotating shaft, and the lower crushing disc is slidably connected to the guide groove through a guide bar to prevent relative rotation between the rotating shaft and the lower crushing disc.

[0012] Furthermore, the top wall of the rectangular shell is fixedly connected to the upper side of the vertically adjacent sliding shell through longitudinally symmetrically distributed telescopic columns and springs. The springs are movably sleeved with the outer ends of the adjacent telescopic columns. A limiting column is provided in the middle of the top wall of the rectangular shell. The extruded brick is ejected from the mold by the spring force.

[0013] Furthermore, a driven shaft is rotatably connected between the front and rear walls of the packing shell via bearings. Both ends of the driven shaft are provided with spiral blades, and the spiral conveying directions of the two spiral blades are opposite. A second motor is provided on the upper side of the packing shell. The input end of the second motor is electrically connected to the output end of the microcontroller. Both the output shaft of the second motor and the front end of the driven shaft are provided with pulleys, and the two pulleys are connected by belt drive. A flexible hose is provided through the middle of the top wall of the packing shell to convey brick powder raw materials to the mold.

[0014] Furthermore, a leveling seat is hinged to the lower right side of the packing shell via evenly distributed hinges. The right side of the packing shell is fixedly connected to the right side of the leveling seat via longitudinally symmetrically distributed curved telescopic rods and springs. Springs are movably sleeved with the outer ends of adjacent curved telescopic rods. The center of the curved telescopic rods coincides with the axis of the hinges, thus performing brick-making packing leveling treatment on the device.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: This equipment for mixing, crushing, and powdering construction waste and slag to make bricks has the following advantages:

[0016] 1. The single-chip microcomputer starts the electric pole, causing its telescopic end to move the circular seat vertically. The circular seat drives the lower crushing disc to move vertically along the guide groove through the annular groove, thereby adjusting the crushing gap of the device. During this process, the lower crushing disc moves vertically along the guide groove through the guide bar. It is easy to use. This equipment for mixing and crushing construction waste and slag and making powder bricks has adjustable crushing gaps and a wide range of applications.

[0017] 2. External humidifying powder falls through a hose onto the upper right side of the mold. Then, the microcontroller starts motor two, which drives the upper pulley to rotate. The upper pulley drives the lower driven shaft to rotate the spiral blade through belt transmission. The spiral blade conveys the humidifying powder to the front and rear ends of the upper mold through spiral rotation. Then, the hydraulic pump causes the telescopic end of the hydraulic rod four to move slowly to the left horizontally. Through the compression force of spring two and the adaptive contraction of the curved telescopic rod, the leveling seat squeezes and levels the brick-making powder on the upper end of the mold. This construction waste and slag mixing, crushing and powder brick-making equipment can automatically and elastically level the powder brick-making raw materials when supplying brick-making raw materials to the mold, reducing the intensity of manual labor.

[0018] 3. The hydraulic pump causes the telescopic end of the hydraulic rod to move the lower pressure seat vertically downward to extrude the humidified powder in the mold to form bricks. During this process, the lower surface of the sliding shell first contacts the upper end of the humidified powder in the mold. Through the contact pressure, the sliding shell moves into the interior of the rectangular shell. The telescopic end of the telescopic column and the spring retract until the upper surface of the sliding shell contacts the bottom of the limiting column. After the powder is made into bricks, the hydraulic pump causes the rectangular shell and the mold to move vertically upward. During this process, the compression force of the spring drives the sliding shell to squeeze the extruded bricks in the mold onto the tray, preventing material from sticking inside the mold. This construction waste and slag mixing, crushing, and powder brick-making equipment can squeeze the extruded bricks out of the mold through the spring force, avoiding the phenomenon of extrusion and adhesion between the two.

A mold 14 is provided between the front and rear ends of the right side of the top wall of the brick-making frame 2 via a liquid rod 2 13. A connecting seat is provided on the left side of the top wall of the brick-making frame 2 via a liquid rod 3 15. A packing shell 17 is provided on the right side of the connecting seat via a liquid rod 4 16. The packing shell 17 and the sliding shell 9 are both installed in conjunction with the mold 14.

[0029] Crushing mechanism 4: Located inside the crushing shell 1, crushing mechanism 4 includes a cross 41, a rotating shaft 42, a lower crushing disc 43, an upper crushing disc 44, a drive shaft 45, a bevel gear 46, and a motor 47. The cross 41 is located inside the crushing shell 1. The upper side of the cross 41 is rotatably connected to the rotating shaft 42 via bearings. The upper end of the rotating shaft 42 is slidably connected to the lower crushing disc 43. The top wall of the crushing shell 1 is provided with the upper crushing disc 44, which is installed in conjunction with the lower crushing disc 43. The right wall of the crushing shell 1 is rotatably connected to the drive shaft 45 via bearings. Both the left end of the drive shaft 45 and the lower end of the rotating shaft 42 are provided with bevel gears 46. Two bevel gears 46 mesh with each other. The input end of the motor 47 located on the right side of the crushing shell 1 is electrically connected to the output end of the microcontroller 3. The output shaft of the motor 47 is fixedly connected to the right end of the drive shaft 45. The crushing mechanism 4 also includes an electric rod 48 and an annular groove 49. The electric rod 48 is located on the upper surface of the cross 41. The input end of the electric rod 48 is electrically connected to the output end of the microcontroller 3. A round seat is slidably connected in the annular groove 49 opened on the lower side of the lower crushing disc 43.

[0030] Specifically, in this configuration, construction waste and slag are fed into the crushing shell 1 through the feed hopper.

This construction waste and slag mixed crushing and powder brick making equipment has adjustable crushing gap and a wide range of applications. Example 2

[0031] The difference between this embodiment and Embodiment 1 is that:

[0032] In this embodiment, the top wall of the rectangular shell 8 is fixedly connected to the upper side of the vertically adjacent sliding shell 9 through longitudinally symmetrically distributed telescopic columns 10 and springs 11. The springs 11 are movably sleeved with the outer ends of the adjacent telescopic columns 10. The middle part of the top wall of the rectangular shell 8 is provided with a limiting column 12.

[0033] Specifically, in this configuration, the packing shell 17 is then reset, and the hydraulic pump causes the telescopic end of the hydraulic rod 6 to move the lower pressure seat 7 vertically downward to extrude the humidified powder in the mold 14 to form bricks. During this process, the lower surface of the sliding shell 9 first contacts the upper end of the humidified powder in the mold 14. Through the contact pressure, the sliding shell 9 moves into the interior of the rectangular shell 8, and the telescopic end of the telescopic column 10 and the spring 11 retract until the upper surface of the sliding shell 9 contacts the bottom of the limiting column 12. After the powder is made into bricks, the hydraulic pump causes the rectangular shell 8 and the mold 14 to move vertically upward. During this process, the compression force of the spring 11 drives the sliding shell 9 to squeeze the extruded bricks in the mold 14 onto the tray, preventing material from sticking inside the mold 14. This construction waste and slag mixing, crushing, and powder brick-making equipment can squeeze the extruded bricks out of the mold 14 through the spring force, avoiding the phenomenon of extrusion and adhesion between the two. Example 3

[0034] The difference between this embodiment and Embodiment 1 is that:

[0035] In this embodiment, a driven shaft 18 is rotatably connected between the front and rear walls of the packing shell 17 via bearings. Both ends of the driven shaft 18 are provided with spiral blades 25, and the spiral conveying directions of the two spiral blades 25 are opposite. A second motor 21 is provided on the upper side of the packing shell 17. The input end of the second motor 21 is electrically connected to the output end of the single-chip microcomputer 3. The output shaft of the second motor 21 and the front end of the driven shaft 18 are both provided with pulleys 19. The two pulleys 19 are connected by a belt 20. A flexible hose 26 is provided through the middle of the top wall of the packing shell 17. A leveling seat 22 is hinged to the lower right side of the packing shell 17 via evenly distributed hinges. The right side of the packing shell 17 is fixedly connected to the right side of the leveling seat 22 via longitudinally symmetrically distributed curved telescopic rods 23 and springs 24. The springs 24 are movably sleeved with the outer ends of the adjacent curved telescopic rods 23. The center of the curved telescopic rods 23 coincides with the axis of the hinges.

[0036] Specifically, the setup involves filtering and humidifying the crushed construction waste and slag using an external device. The humidified powder is then conveyed to hose 26 via a conveying device. A pallet is manually placed on the upper left side of the chain-type electric conveyor belt 27. The microcontroller 3 activates the chain-type electric conveyor belt 27, moving the pallet to the lower end of mold 14. A hydraulic pump then causes the extension end of hydraulic rod 23 to move mold 14 down to the upper end of the pallet. Next, a hydraulic pump causes the extension end of hydraulic rod 4 16 to move the packing shell 17 to the right side of the upper end of mold 14. The hydraulic pump controls hydraulic rod 3 15 to make its extension end contact the lower side of the packing shell 17 with the upper right surface of mold 14. The external humidified powder falls into mold 14 through hose 26. On the upper right side of the mold 14, the microcontroller 3 starts the motor 21, which drives the upper pulley 19 to rotate. The upper pulley 19 drives the lower driven shaft 18 to rotate the spiral blade 25 through belt transmission. The spiral blade 25 conveys the humidified powder to the front and rear ends of the upper side of the mold 14 through spiral rotation. Then, the hydraulic pump causes the telescopic end of the hydraulic rod 16 to move slowly to the left horizontally. Through the compression force of the spring 24 and the adaptive contraction of the curved telescopic rod 23, the leveling seat 22 squeezes and levels the brick-making powder on the upper end of the mold 14. The operation is convenient. This construction waste and slag mixing crushing and powder brick-making equipment can automatically and elastically level the powder brick-making raw materials when supplying brick-making raw materials to the mold 14, reducing the intensity of manual labor.

[0037] The working principle of the construction waste and slag mixed crushing and powder brick-making equipment provided by this invention is as follows: First, the internal hydraulic rod of the device is connected to the external hydraulic pump. Construction waste and slag are fed into the crushing shell 1 through the feed hopper. The microcontroller 3 starts the motor 47 to drive the drive shaft 45 to rotate. The drive shaft 45 drives the bevel gear 46 to rotate the rotating shaft 42 through meshing. The rotating shaft 42 drives the lower crushing disc 43 to rotate relative to the upper crushing disc 44 through the guide groove 5, thereby crushing the construction waste and slag mixture. During this process, the circular seat and the annular groove 49 rotate and slide adaptively. The microcontroller 3 starts the electric rod 48 to drive the extension end to move the circular seat vertically. The circular seat drives the lower crushing disc 43 along the guide groove through the annular groove 49. 5. The device moves vertically to adjust the crushing gap. During this process, the lower crushing disc 43 moves vertically along the guide groove 5 via the guide bar, making it easy to use. The crushed material is collected through the feed pipe, and then the crushed construction waste and slag are filtered and humidified by an external device. The humidified and mixed material powder is then conveyed to the hose 26 by the conveying device. The pallet is then manually placed on the upper left side of the chain plate electric conveyor belt 27. The microcontroller 3 starts the chain plate electric conveyor belt 27 to move the pallet to the lower end of the mold 14. Then, the hydraulic pump causes the extension end of the hydraulic rod 2 13 to move the mold 14 down to the upper end of the pallet. Then, the hydraulic pump causes the extension end of the hydraulic rod 4 16 to move the packing shell 17 to the right. At the upper right side of the mold 14, the hydraulic pump controls the hydraulic rod 15 to extend and retract, causing the lower side of the packing shell 17 to contact the upper right surface of the mold 14. External humidifying powder falls through the hose 26 onto the upper right side of the mold 14. Then, the microcontroller 3 starts the motor 21, causing the upper pulley 19 to rotate. The upper pulley 19, through belt transmission, causes the lower driven shaft 18 to rotate the spiral blade 25. The spiral blade 25, through its spiral rotation, transports the humidifying powder to the front and rear ends of the upper side of the mold 14. Subsequently, the hydraulic pump causes the extension and retraction end of the hydraulic rod 16 to move slowly horizontally to the left. Through the compression force of the spring 24 and the adaptive contraction of the curved extension rod 23, the scraper seat 22 contacts the upper end of the mold 14. The brick-making powder is extruded and scraped flat, making the operation convenient. Then, the filler shell 17 is reset, and the hydraulic pump causes the telescopic end of the hydraulic rod 6 to move the lower pressure seat 7 vertically downward to extrude the humidified powder in the mold 14 to make bricks. During this process, the lower surface of the sliding shell 9 first contacts the upper end of the humidified powder in the mold 14. Through the contact pressure, the sliding shell 9 moves into the interior of the rectangular shell 8. The telescopic end of the telescopic column 10 and the spring 11 retract until the upper surface of the sliding shell 9 contacts the bottom of the limiting column 12. After the powder is made into bricks, the hydraulic pump causes the rectangular shell 8 and the mold 14 to move vertically upward. During this process, the compression force of the spring 11 drives the sliding shell 9 to squeeze the extruded bricks in the mold 14 onto the tray, preventing material from sticking inside the mold 14.
