Description

Technical Field

[0001] The present application relates to the technical field of permeable brick preparation, and in particular to a device and process for preparing permeable bricks using waste concrete. Background Art

[0002] Permeable bricks are environmentally friendly porous materials made primarily from concrete, which is then mixed with river sand, cement, and water, and then a permeable agent is added. The color depends on the added colorant. Permeable bricks come in two types: fired and unfired. Their excellent permeability allows rainwater to quickly seep through their pores, leading to their widespread use in sponge city construction.

[0003] In the related art, a Chinese patent with announcement number CN219726651U discloses a device for preparing permeable bricks using industrial solid waste. The technical key points are: it includes a preparation shell, the top of the preparation shell is clamped with a first bearing, the first bearing is sleeved with a grinding wheel, and a plurality of second bearings are clamped with a surface of the grinding wheel, the second bearings are sleeved with extrusion rollers, the grinding wheel is arranged above the grinding frame, the grinding frame is fixed to the inner wall of the preparation shell, a stirring rod is installed at the bottom of the grinding wheel, the top of the grinding wheel is fixedly connected to the output shaft of the first motor, the first motor is fixedly connected to one side of the feed port, and the bottom of the preparation shell is provided with a discharge port.

[0004] Permeable bricks made from waste materials are unfired, meaning they do not require a high-temperature sintering process. These bricks are formed using a press and then hardened and solidified through a curing process. The above-mentioned device, after feeding solid waste, grinds the waste material. After grinding, a binder and other ingredients are added, and the material is stirred and pressed to produce the permeable bricks. Since the solid waste may contain metal impurities such as iron wire and nails, these impurities can easily clog the pores within the permeable bricks, reducing the permeable area and affecting the permeability. Summary of the Invention

[0005] In order to reduce the influence of metal impurities in waste concrete on the water permeability of formed permeable bricks, the present application provides a device and process for preparing permeable bricks using waste concrete.

[0006] The present application provides a device and process for preparing permeable bricks using waste concrete, which adopts the following technical solutions:

[0007] In a first aspect, the present application provides a device for preparing permeable bricks using waste concrete, which adopts the following technical solution:

[0008] The cam is fixedly mounted on the frame, and the guide frame is arranged on the frame to move relative to the magnetic separator.

[0009] By adopting the above technical solution, waste concrete falls on the top surface of the turntable. Under the restriction of the spiral guide frame, the turntable rotates and drives the waste concrete to gradually move toward the center of the turntable. During the movement of the waste concrete, metal impurities are adsorbed by the magnetic plate, thereby removing impurities. Since the waste concrete moves along the spiral path, the impurity removal time of the waste concrete can be extended, thereby enhancing the impurity removal effect.

[0010] Optionally, a cleaning assembly is provided on the box body, and the cleaning assembly includes a power telescopic part, a scraper, a receiving plate and a collection frame. The power telescopic part is fixedly connected to the box body, and the telescopic direction of the movable end of the power telescopic part is parallel to the plate surface of the magnetic plate. The scraper is fixedly connected to the movable end of the power telescopic part. The scraper is located on the side of the magnetic plate close to the guide frame and is against the magnetic plate. The receiving plate is arranged on the scraper for temporarily storing metal impurities scraped off by the scraper. The collection frame is fixedly connected to the side wall of the box body and is located at the end of the scraper moving path.

[0011] By adopting the above technical solution, the scraper slides and pushes the metal impurities adsorbed on the magnetic plate into the collection frame, which is convenient for collection. At the same time, it can avoid the magnetic plate from adsorbing too much metal impurities and affecting the adsorption effect of the magnetic plate.

[0012] Optionally, a limit rod arranged along the sliding direction of the scraper is fixedly connected to the inner wall of the box, the scraper and the receiving plate are rotatably connected, and an elastic member is connected between the scraper and the receiving plate, and the elastic member makes the receiving plate press against the limit rod. When the scraper is located at the end of the limit rod, the elastic member makes the receiving plate rotate to the side away from the scraper so that the metal impurities on the receiving plate fall into the collection frame.

[0013] By adopting the above technical solution, when the scraper slides, the receiving plate can receive the metal impurities that accidentally fall from the magnetic plate, thereby preventing the separated metal impurities from falling into the raw material again; when the scraper moves to the end of the limit rod, the elastic part can make the receiving plate rotate downward, so that the metal impurities on the receiving plate fall into the collection frame, and when the scraper moves in the opposite direction again, it is restricted by the limit rod and the receiving plate rotates upward to a horizontal state, so as to facilitate the reception of metal impurities that accidentally fall from the magnetic plate in the next stroke.

[0014] Optionally, the scraper includes a mounting frame and an abutment plate, the mounting frame is fixedly connected to the movable end of the power telescopic member, one end of the abutment plate is slidably set in the mounting frame along the height direction of the box body, and the end of the abutment plate away from the mounting frame can abut against the magnetic plate, a first magnetic member is fixedly connected in the mounting frame, and a second magnetic member that is attracted to the first magnetic member is fixedly connected to the abutment plate, when the abutment plate slides, the first magnetic member and the second magnetic member remain in an attracted state, and an adjustment component for driving the abutment plate to slide is provided between the abutment plate and the box body.

[0015] By adopting the above technical solution, the cooperation of the first magnetic part and the second magnetic part can ensure that the abutment plate can stay at the current position when it slides to any position; the adjusting part can adjust the position of the abutment plate, so that when the scraper slides toward the side close to the collection frame, the abutment plate and the magnetic plate abut against each other, thereby pushing down the metal impurities adsorbed on the magnetic plate; when the scraper slides toward the side away from the collection frame, the abutment plate and the magnetic plate are spaced apart, so that the abutment plate will not contact the magnetic plate during the sliding process, and the scraper performs one-way cleaning, which can avoid accidentally pushing down the metal impurities on the magnetic plate when the scraper slides toward the side away from the collection frame.

[0016] Optionally, the adjusting component includes a first mounting block and a second mounting block fixedly connected to the inner wall of the box body, the first mounting block and the second mounting block are respectively located at two ends of the magnetic plate, and the first mounting block is located on the side away from the collection frame, a first inclined surface is provided on the first mounting block, a second inclined surface is provided on the second mounting block, a third mounting block is fixedly connected to the abutment plate, and a third inclined surface is provided on the third mounting block, when the scraper slides toward the side close to the first mounting block, the first inclined surface causes the abutment plate to slide toward the side close to the magnetic plate, and when the scraper slides toward the side close to the second mounting block, the second inclined surface causes the abutment plate to slide toward the side away from the magnetic plate.

[0017] By adopting the above technical solution, when the scraper slides to the side away from the collection frame, the third mounting block can be abutted against the first mounting block, and with the cooperation of the first inclined surface and the third inclined surface, the abutment plate can slide upward while sliding horizontally, so that the abutment plate abuts against the magnetic plate; when the scraper slides to the side close to the collection frame, the third mounting block can be abutted against the second mounting block, and with the cooperation of the second inclined surface and the third inclined surface, the abutment plate can slide downward while sliding horizontally, so that the abutment plate is separated from the magnetic plate.

[0018] Optionally, a wind separation component is provided in the box, and the wind separation component includes a blower. The blower is located on the side of the turntable close to the bottom of the box, and the air outlet of the blower is facing the box. A separation port for removing lighter materials is provided on the side wall of the box, and a accommodating cavity for accommodating heavier materials is provided at the bottom of the box.

[0019] By adopting the above technical solution, light impurities such as wood, paper, and plastic can be separated from waste concrete under the action of wind, thereby enhancing the impurity removal effect on waste concrete.

[0020] Optionally, a guide plate is fixedly connected to the box body, and the guide plate is located on the side of the turntable close to the bottom of the box body. The guide plate is arranged in an upwardly protruding conical surface, and a discharge hole is opened on the guide plate.

[0021] By adopting the above technical solution, when the raw materials fall after magnetic separation, they slide downward along the top surface of the guide plate, and then fall through the discharge holes on the guide plate or the bottom end of the guide plate, thereby expanding the distribution range of the raw materials when falling, allowing the raw materials to be more fully in contact with the wind, and enhancing the separation effect.

[0022] Optionally, a vibration mechanism is provided in the box body, and the vibration mechanism includes a wind force member, a guide shell, a knocking member and a first ventilation pipe. The wind force member is rotatably provided in the box body, and the rotation axis of the wind force member is provided along the height direction of the box body. The guide shell is fixedly connected to the bottom wall of the turntable, and one end of the knocking member is slidably provided in the guide shell along the height direction of the box body. The first ventilation pipe is fixedly connected to the box body, and one end of the first ventilation pipe is connected to the air outlet of the blower, and the other end of the first ventilation pipe faces the wind force member, so that the blower drives the wind force member to rotate, and the wind force member intermittently resists the knocking member, and causes the knocking member to intermittently hit the turntable.

[0023] By adopting the above technical solution, when blowing, the wind force piece can also be driven to rotate. When the wind force piece rotates, the knocking piece can slide back and forth in the vertical direction, so that the top of the knocking piece intermittently knocks the turntable, causing the turntable to vibrate, so that the raw materials on the turntable are more dispersed, making it easier for metal impurities in the raw materials to be adsorbed by the magnetic plate, thereby enhancing the separation effect; since the sliding of the knocking piece is driven by the wind force of the blower, there is no need to set up an additional power source, so it is more energy-saving.

[0024] Optionally, a push block is fixedly connected to the wind force member, the push block is located on the side of the knocking member away from the turntable, a fourth inclined surface is provided on the side of the push block close to the turntable, and the side of the knocking member away from the turntable is set to be hemispherical.

[0025] By adopting the above technical solution, the cooperation between the fourth inclined surface and the hemispherical end makes it easier to drive the knocking member to slide when the wind force member rotates, which helps the knocking member to slide smoothly.

[0026] In a second aspect, the present application provides a process for preparing permeable bricks, which adopts the following technical solution:

[0027] A process using any of the above-mentioned devices for preparing permeable bricks comprises the following steps:

[0028] a. Crushing the waste concrete;

[0029] b. Screen the crushed material to obtain particles of the required size;

[0030] c. The screened material falls onto the turntable through the feed port on the box. The turntable rotates, causing the material to gradually move toward the center of the turntable along the guide frame. The magnetic plate separates the metal in the material, and the material falls from the drop port on the turntable;

[0031] d. Add the required raw materials to the materials after impurities removal and mix them;

[0032] e. Pressing the mixed raw materials into permeable bricks of the desired shape;

[0033] f. Curing the permeable bricks for a period of time and drying them after curing is completed.

[0034] By adopting the above technical solution, waste concrete can be crushed, screened and impurity-removed in sequence, mixed with other raw materials, and then pressed. Finally, it can be made into permeable bricks through curing and drying, so that waste concrete is fully utilized and resource utilization is improved.

[0035] In summary, this application includes at least one of the following beneficial technical effects:

[0036] 1. Under the restriction of the guide frame, the waste concrete can move along the guide frame from the edge of the turntable to the center of the turntable as the turntable rotates. During the movement of the waste concrete, the metal impurities inside can be sucked out by the magnetic plate, thereby realizing the separation of the metal impurities, which helps to reduce the influence of the metal impurities on the permeability of the subsequently formed permeable bricks.

[0037] 2. After magnetic separation, the raw materials will be separated by wind again during the falling process, so as to separate the light impurities mixed inside and further enhance the impurity removal effect.

[0038] 3. When the blower is working, the wind force part can be rotated, so that the knocking part can intermittently slide up and down. The knocking part can intermittently knock on the turntable, so that the turntable can vibrate, making the raw materials on the turntable more dispersed, which helps to enhance the adsorption effect of the magnetic plate.

DETAILED DESCRIPTION

[0047] The following is combined with Figure 1-7 This application is described in further detail.

[0048] The embodiment of the present application discloses a device for preparing permeable bricks using waste concrete, which includes a crushing mechanism, a screening mechanism, a debris removal mechanism, a mixing mechanism, and a pressing mechanism that are arranged in sequence.

[0049] Among them, the crushing mechanism is used to crush the input materials; the screening mechanism can screen the crushed materials to screen out smaller particles of the required size; the impurity removal mechanism can remove impurities in the screened materials to facilitate the subsequent forming of permeable bricks; the mixing mechanism can mix the impurity-removed materials with other raw materials; the pressing mechanism can press the mixed raw materials into permeable bricks. After the pressing is completed, the permeable bricks are taken out and cured and dried for a period of time.

[0050] Reference Figure 1 and Figure 2 The impurity removal mechanism includes a housing 1 and a magnetic separation assembly 2. Housing 1 is vertically arranged, with a feed port 11 defined at the top. Raw materials, after crushing and screening, are fed into housing 1 through feed port 11 for magnetic separation. Magnetic separation assembly 2, located within housing 1, removes metallic impurities from the raw materials. After magnetic separation, the raw materials fall to the bottom of housing 1.

[0051] Reference Figure 3 and Figure 4The magnetic separation component 2 includes a rotating power part 21, a turntable 22, a guide frame 23 and a magnetic plate 24. The rotating power part 21 is a motor, and the rotating power part 21 is arranged on the inner side of the box body 1, and the output shaft of the rotating power part 21 is vertically upward. The turntable 22 is located at the top of the inner side of the box body 1, and the turntable 22 is located above the rotating power part 21, and the axis of the turntable 22 is coaxially arranged with the output shaft of the rotating power part 21. A blanking port 221 is coaxially opened at the center of the turntable 22, and a connecting rod 222 is fixedly connected to the inner wall of the blanking port 221; the output shaft end of the rotating power part 21 is coaxially fixedly connected to the rotating rod 211, and the top end of the rotating rod 211 is fixedly connected to the connecting rod 222; therefore, the rotating power part 21 can drive the turntable 22 to rotate through the rotating rod 211. A conical cover 212 is fixedly connected to the rotating rod 211 and is arranged above the rotating power part 21, so that the material falling from the drop port 221 can be blocked to prevent the material from falling directly onto the rotating power part 21, which helps to ensure the normal operation of the rotating power part 21.

[0052] The guide frame 23 is fixedly connected to the inner wall of the housing 1 and is located above the turntable 22. The guide frame 23 is spirally arranged coaxially with the turntable 22, and the bottom wall of the guide frame 23 abuts the top wall of the turntable 22. One end of the guide frame 23 is located at the outer edge of the turntable 22, and the other end of the guide frame 23 is located at the drop opening 221. The feed opening 11 on the housing 1 is located directly above the edge of the turntable 22. Therefore, after the waste concrete raw material is fed into the housing 1 through the feed opening 11, the raw material falls to the edge directly above the turntable 22. When the rotating power member 21 is in operation, it drives the turntable 22 to rotate, and when the turntable 22 rotates, the raw material also rotates. Because the guide frame 23 is fixed, the raw material moves along the guide frame 23 under the restraining effect of the guide frame 23 during rotation, gradually moving from the edge of the turntable 22 to the center of the turntable 22, and then falling through the drop opening 221 on the turntable 22.

[0053] Magnetic separation assembly 2 also includes a horizontally disposed magnetic plate 24 fixedly attached to the inner wall of housing 1. Magnetic plate 24 is a rectangular plate, spaced apart and positioned directly above guide frame 23. The bottom surface of magnetic plate 24 is magnetic, allowing it to attract metal. Therefore, as the raw material moves along the spiral trajectory, metal in the raw material is attracted to the bottom surface of magnetic plate 24, thereby separating the metallic impurities from the raw material.

[0054] Reference Figure 4The box body 1 is also provided with a cleaning assembly 3, which includes a power telescopic member 31, a scraper 32, a receiving plate 33 and a collection frame 34. The power telescopic member 31 is a cylinder, which is fixedly connected to the inner wall of the box body 1 by bolts, and the telescopic direction of the piston rod of the power telescopic member 31 is set horizontally. The scraper 32 is fixedly connected to the end of the piston rod of the power telescopic member 31, and the scraper 32 is located below the magnetic plate 24, and the top of the scraper 32 is against the bottom wall of the magnetic plate 24; thus, the power telescopic member 31 can drive the scraper 32 to move, thereby pushing down the metal impurities adsorbed on the magnetic plate 24. The receiving plate 33 is arranged at the bottom end of the scraper 32, and the receiving plate 33 can receive the metal impurities that accidentally fall from the magnetic plate 24 during the sliding process of the scraper 32. The collection frame 34 is fixedly connected to the side wall of the box body 1. The collection frame 34 is located at one end of the magnetic plate 24 and below the magnetic plate 24, with the opening of the collection frame 34 facing upward. Therefore, metal impurities adsorbed on the bottom wall of the magnetic plate 24 can be pushed into the collection frame 34 by the scraper 32, facilitating the collection of the metal impurities.

[0055] Reference Figure 5 The scraper 32 includes a mounting frame 321 and an abutment plate 322. The mounting frame 321 is fixedly connected to the piston rod end of the power telescopic member 31, and the length direction of the mounting frame 321 is horizontally arranged; the top of the mounting frame 321 is provided with a slide groove 3211 along its own length direction, and the depth direction of the slide groove 3211 is vertically arranged; the bottom end of the abutment plate 322 is slidably arranged in the slide groove 3211 along the vertical direction, and the top end of the abutment plate 322 is sharp, and the top end of the abutment plate 322 can abut against the bottom wall of the magnetic plate 24. A first magnetic part 3212 is clamped and fixed on the inner wall of the slide groove 3211, and a second magnetic part 3221 is clamped and fixed on the outer wall of the abutment plate 322 at one end inside the slide groove 3211. The first magnetic part 3212 and the second magnetic part 3221 are both magnets, and the first magnetic part 3212 and the second magnetic part 3221 are in contact with each other; the magnetic poles of the first magnetic part 3212 and the second magnetic part 3221 are in opposite directions on the side close to each other, so the first magnetic part 3212 and the second magnetic part 3221 are attracted together, so that the abutment plate 322 can stay at the current position after sliding to any position of the slide groove 3211.

[0056] Reference Figure 6 and Figure 7The housing 1 is provided with an adjustment component 4, which includes a first mounting block 41 and a second mounting block 42. The first mounting block 41 and the second mounting block 42 are both fixedly connected to the inner wall of the housing 1, and are respectively located at the two ends of the magnetic plate 24; the first mounting block 41 is located on the side away from the collection frame 34, and the second mounting block 42 is located on the side close to the collection frame 34. The first mounting block 41 has a first inclined surface 411 on the side close to the collection frame 34, and the second mounting block 42 has a second inclined surface 421 on the side away from the collection frame 34; the end of the abutment plate 322 located outside the slide groove 3211 is fixedly connected to a third mounting block 43, and both ends of the third mounting block 43 have a third inclined surface 431. The first inclined surface 411, the second inclined surface 421, and the third inclined surface 431 have the same inclination direction and degree; and the second mounting block 42 is located at a higher height than the first mounting block 41.

[0057] When the power telescopic member 31 drives the abutting plate 322 to slide toward the side close to the collection frame 34 through the mounting frame 321, the top of the abutting plate 322 abuts against the bottom wall of the magnetic plate 24, thereby scraping off the metal impurities adsorbed on the magnetic plate 24. During this process, the third mounting block 43 is located at the same height as the second mounting block 42. When the abutting plate 322 moves to one end close to the collection frame 34, the third inclined surface 431 on the third mounting block 43 abuts against the second inclined surface 421 on the second mounting block 42. Then, as the mounting frame 321 slides, the abutting plate 322 slides downward while sliding horizontally, causing the abutting plate 322 to slide into the slide groove 3211, and the abutting plate 322 is out of contact with the magnetic plate 24. When the abutting plate 322 slides downward, it drives the third mounting block 43 downward, causing the third mounting block 43 to slide to the same height as the first mounting block 41.

[0058] The piston rod end of the power telescopic member 31 is then retracted, causing the mounting frame 321 to drive the abutment plate 322 to slide toward the side away from the collection frame 34. When the mounting frame 321 slides to the end of the magnetic plate 24 away from the collection frame 34, the third inclined surface 431 on the third mounting block 43 and the first inclined surface 411 on the first mounting block 41 abut against each other. Then, as the mounting frame 321 slides, the abutment plate 322 slides upward while sliding horizontally until the top of the abutment plate 322 abuts against the bottom wall of the magnetic plate 24. The piston rod end of the power telescopic member 31 then slides back and forth, causing the scraper 32 to slide back and forth, thereby cleaning the metal impurities adhering to the magnetic plate 24.

[0059] Reference Figure 6To facilitate the removal of metal impurities that fall onto the receiving plate 33, the receiving plate 33 is hinged to the bottom wall of the mounting frame 321, with the hinge axis of the receiving plate 33 extending along the length of the mounting frame 321. A limit rod 14 is fixedly connected to the inner wall of the housing 1 and extends along the sliding direction of the piston rod of the power telescopic member 31. The limit rod 14 is spaced below the magnetic plate 24. Under normal conditions, the receiving plate 33 is horizontally positioned, with the bottom wall of the receiving plate 33 abutting against the top wall of the limit rod 14. Therefore, during the sliding of the installation frame 321, the limit rod 14 supports the receiving plate 33 so that the receiving plate 33 is horizontal, and the receiving plate 33 can receive the metal impurities falling from the magnetic plate 24; when the installation frame 321 slides to one end close to the collection frame 34, the receiving plate 33 rotates downward due to the loss of the support of the limit rod 14, so the metal impurities on the receiving plate 33 can fall into the collection frame 34; when the installation frame 321 slides to the side away from the collection frame 34, due to the action of the limit rod 14, the receiving plate 33 will rotate upward to a horizontal state and play a receiving role again.

[0060] Reference Figure 5 Furthermore, an elastic member 5 is provided between the receiving plate 33 and the mounting frame 321. The elastic member 5 is a torsion spring. The elastic member 5 makes the receiving plate 33 press against the limiting rod 14. Therefore, the setting of the elastic member 5 makes it easier for the receiving plate 33 to rotate downward when the mounting frame 321 moves to one end close to the collection frame 34.

[0061] After crushing, screening and magnetic separation, waste concrete mainly contains concrete particles, bricks, sand, gravel and other raw materials, which can be used for the subsequent production of permeable bricks. There are also some light impurities such as paper, wood chips and plastics mixed in it. In order to separate these light impurities, refer to Figure 2 The box 1 is provided with a wind separation assembly, comprising a blower 6 fixedly connected to the outer wall of the box 1. The air outlet of the blower 6 is connected to a second ventilation pipe 61, the end of the second ventilation pipe 61 located within the box 1, away from the blower 6. The end of the second ventilation pipe 61 located within the box 1 is located below the turntable 22, and the end of the second ventilation pipe 61 located within the box 1 is tilted upward. A separation port 12 is defined in the side wall of the box 1 away from the blower 6. The separation port 12 is located below the turntable 22. A receiving chamber 13 is provided at the bottom of the box 1. Therefore, when the blower 6 is activated, air is blown into the box 1. After the raw materials undergo magnetic separation, they fall through the dropout port 221 on the turntable 22. After being blown by the air, the lighter impurities in the raw materials are discharged through the separation port 12, while the heavier materials fall into the receiving chamber 13 at the bottom of the box 1, facilitating subsequent mixing.

[0062] Reference Figure 3Furthermore, a guide plate 7 is fixedly connected to the inner wall of the box body 1 just below the turntable 22. The guide plate 7 is arranged in the shape of a conical surface with a vertical axis, and the tip of the guide plate 7 faces upward; a plurality of discharge holes 71 are opened on the guide plate 7, so that the raw materials falling from the drop opening 221 on the turntable 22 can first fall onto the guide plate 7, and then the raw materials slide downward along the top wall of the guide plate 7. Part of the raw materials fall through the discharge holes 71 on the guide plate 7, and part of the raw materials fall from the bottom end of the guide plate 7, thereby expanding the dispersion range of the fallen raw materials, allowing the raw materials to be more fully in contact with the wind blown by the blower 6, which helps to enhance the separation effect of the raw materials.

[0063] The housing 1 also houses a vibration mechanism 8, which includes a wind element 81, a guide housing 82, a striking element 83, and a first ventilation pipe 84. The wind element 81 comprises a mounting ring 811 and a windshield 812. The mounting ring 811 is coaxial with the turntable 22 and is located directly below the turntable 22. The inner diameter of the mounting ring 811 is larger than the diameter of the drop opening 221, thereby facilitating the smooth descent of the raw materials from the turntable 22. The windshield 812 is fixedly attached to the bottom wall of the mounting ring 811. Multiple windshields 812 are provided, arranged in a circular array, and are hemispherical in shape. A ring rail 15 coaxially arranged with the turntable 22 is also fixedly connected to the inner wall of the box body 1, and the ring rail 15 is located on the outside of the mounting ring 811; a guide block 8111 is fixedly connected to the outer wall of the mounting ring 811, and a ring-shaped guide groove 151 is provided on the ring rail 15. The guide block 8111 slides and engages in the guide groove 151, so that the mounting ring 811 is rotatably arranged on the inner side of the ring rail 15.

[0064] The guide shells 82 are fixedly connected to the bottom wall of the turntable 22. There are two groups of guide shells 82. The two groups of guide shells 82 are spaced apart, and each group of guide shells 82 is arranged in a circular array. The height direction of the guide shells 82 is vertical. There are multiple knocking members 83, and the number is the same as the number of guide shells 82. Each knocking member 83 is set in a guide shell 82. The knocking member 83 is cylindrical and is slidably set in the guide shell 82 along the vertical direction. The top of the knocking member 83 can contact the bottom wall of the turntable 22. Under normal circumstances, the top of the knocking member 83 and the bottom wall of the turntable 22 are spaced apart. The bottom end of the knocking member 83 is located on the outside of the guide shell 82. A push block 9 is fixedly connected to the top wall of the mounting ring 811. The push block 9 is located below the knocking member 83. There are multiple push blocks 9, and the number is the same as the number of knocking members 83. Each push block 9 corresponds to a knocking member 83.

[0065] The first ventilation pipe 84 is fixedly connected to the outer wall of the box body 1, and one end of the first ventilation pipe 84 is connected to the air outlet of the blower 6, and the direction of the outlet of the other end of the first ventilation pipe 84 is horizontally arranged and faces the wind shield 812. Therefore, after the blower 6 is started, a part of the air is discharged through the first ventilation pipe 84, so that the wind shield 812 drives the mounting ring 811 to rotate, and the mounting ring 811 drives the push block 9 to rotate when rotating. When the push block 9 rotates, it can first abut against the bottom end of the corresponding knocking member 83, and then as the push block 9 rotates, the push block 9 disengages from the abutment with the knocking member 83, so that the knocking member 83 can slide back and forth in the vertical direction. When the knocking member 83 slides upward, it can contact the bottom wall of the turntable 22, thereby intermittently knocking the turntable 22, causing the turntable 22 to vibrate. Therefore, the raw materials on the top surface of the turntable 22 can be distributed more dispersedly, which helps to enhance the separation effect of the magnetic plate 24.

[0066] It should be noted that the rotation direction of the mounting ring 811 under the action of wind is opposite to the rotation direction of the turntable 22, which helps to increase the frequency of the reciprocating sliding of the striking block, thereby enhancing the vibration effect.

[0067] The push block 9 has fourth inclined surfaces 91 on both sides of its top, and the bottom of the striking member 83 is hemispherical. The combination of the fourth inclined surfaces 91 and the hemispherical shape makes it easier for the push block 9 to push the striking member 83 to slide when the push block 9 rotates. A rubber pad is also bonded to the top of the striking member 83, thereby reducing the possibility of the push block 9 getting stuck during the process of pushing the striking member 83 to slide.

[0068] The device for making permeable bricks from waste concrete according to the present invention is implemented as follows: the waste concrete raw material first enters a crushing mechanism for crushing; the crushed raw material falls into a screening mechanism, where smaller particles are screened out for subsequent molding; the screened raw material then enters the housing 1 through the feed port 11 on the housing 1 and falls onto the edge of the top surface of the turntable 22. The rotating power member 21 is activated to drive the turntable 22 to rotate, which in turn drives the raw material on the top surface of the turntable 22 to rotate. Under the restriction of the guide frame 23, the raw material on the turntable 22 moves along the guide frame 23 from the edge of the turntable 22 to the center of the turntable 22; during the movement of the raw material, the magnetic plate 24 absorbs metal impurities in the raw material, thereby removing metal impurities from the raw material. After the raw material has been cleaned, it falls through the drop port 221 in the center of the turntable 22, first onto the top surface of the guide plate 7, and then dispersed and falls through the discharge holes 71 in the guide plate 7 and the bottom end of the guide plate 7. Air from blower 6 blows away light impurities in the raw materials through separation port 12, while heavier materials fall into chamber 13 at the bottom of housing 1. The raw materials in chamber 13 are then transferred to a mixing mechanism, where other raw materials and water are added for mixing. The mixed raw materials are then transferred to a pressing mechanism, where they are pressed into the desired permeable bricks. Finally, the permeable bricks are removed for curing and drying.

[0069] During magnetic separation in the box 1, in the initial state, the abutment plate 322 and the bottom surface of the magnetic plate 24 abut against each other, the receiving plate 33 is in a horizontal state, and the bottom surface of the receiving plate 33 abuts against the top of the limiting rod 14. Then, the piston rod of the power telescopic member 31 extends, causing the mounting frame 321 to drive the abutment plate 322 to slide toward the side close to the collection frame 34. The abutment plate 322 pushes the metal impurities adsorbed on the magnetic plate 24 to move, pushing the metal impurities on the magnetic plate 24 into the collection frame 34. During the sliding process of the abutment plate 322, the receiving plate 33 can receive metal impurities that accidentally fall from the magnetic plate 24. When the abutment plate 322 moves to the side close to the collection frame 34, due to the loss of support from the limiting rod 14, the elastic member 5 causes the receiving plate 33 to rotate downward, and the metal impurities on the receiving plate 33 fall into the collection frame 34. When the abutment plate 322 moves to a side close to the collection frame 34, the third inclined surface 431 on the third mounting block 43 and the second inclined surface 421 on the second mounting block 42 abut against each other, and then as the mounting frame 321 slides, the abutment plate 322 moves downward while sliding horizontally, so that the abutment plate 322 is out of contact with the magnetic plate 24.

[0070] Then, the piston rod of the power telescopic member 31 is retracted, causing the mounting frame 321 and the abutment plate 322 to move away from the collection frame 34. During the movement, since the abutment plate 322 and the magnetic plate 24 do not contact each other, the metal impurities adsorbed on the magnetic plate 24 will not be affected. When the mounting frame 321 moves to the side away from the collection frame 34, the third inclined surface 431 on the third mounting block 43 and the first inclined surface 411 on the first mounting block 41 abut against each other. Then, as the mounting frame 321 moves, the abutment plate 322 slides horizontally and moves upward until the top of the abutment plate 322 abuts against the bottom wall of the magnetic plate 24 again. Through the reciprocating movement of the piston rod of the power telescopic member 31, the abutment plate 322 continuously removes the metal impurities adsorbed on the magnetic plate 24 and moves them into the collection frame 34, ensuring the adsorption effect of the magnetic plate 24.

[0071] In addition, when the blower 6 is working, part of the wind is blown out through the second ventilation pipe 61 to separate the fallen raw materials by wind; the other part of the wind is blown out through the first ventilation pipe 84, and then the wind shield 812 and the mounting ring 811 are rotated. When the mounting ring 811 rotates, it drives the push block 9 to rotate. When the push block 9 rotates, it first contacts the bottom end of the knocking piece 83, and then pushes the knocking piece 83 to move upward. Then the push block 9 gradually breaks away from the contact with the knocking piece 83, causing the knocking piece 83 to move down again. Therefore, the knocking piece 83 can slide back and forth in the vertical direction under the action of the push block 9, and the top of the knocking piece 83 intermittently knocks the turntable 22, thereby causing the turntable 22 to vibrate, making the raw materials on the turntable 22 more dispersed, and further enhancing the adsorption effect of the magnetic plate 24.

[0072] The present application also discloses a process for preparing permeable bricks, comprising the following steps:

[0073] a. Put the waste concrete into the crushing mechanism for crushing;

[0074] b. Transport the crushed raw materials to the screening mechanism to screen out particles of the required size;

[0075] c. The screened raw materials fall onto the turntable 22 through the feed port 11 on the box 1. Under the restriction of the guide frame 23, the turntable 22 rotates to drive the raw materials to move. The raw materials gradually move from the edge of the turntable 22 to the center of the turntable 22. During the movement of the raw materials, the magnetic plate 24 absorbs the metal impurities in the raw materials to achieve metal separation. The separated raw materials fall through the drop port 221;

[0076] d. The blower 6 blows air into the box body 1. The raw materials falling from the drop opening 221 are separated by the wind. Light impurities in the raw materials are discharged through the separation opening 12, and other heavier materials in the raw materials fall into the accommodating cavity 13 at the bottom of the box body 1.

[0077] e. The raw materials in the accommodating chamber 13 are transported to the mixing mechanism, and other required raw materials and water are added and stirred and mixed;

[0078] f. Transport the mixed raw materials to the pressing mechanism to press out the required permeable bricks;

[0079] g. Take out the permeable bricks and carry out curing for a period of time, and then dry them after curing.

[0080] The above are optional embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
