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 a kind of material with environmentally friendly porous structure. The main raw material is concrete, which is then mixed with river sand, cement and water, and then a water-permeable agent is added. The color depends on the added colorant. Permeable bricks are divided into sintered permeable bricks and unfired permeable bricks. Permeable bricks have good water permeability and can make the accumulated water after rain quickly infiltrate through the pores, so they are widely used in the construction of sponge cities.

[0003] In the related art, a Chinese patent with announcement number CN219726651U discloses a device for preparing permeable bricks using industrial solid waste, and its technical highlights are: it includes a preparation shell, a first bearing is clamped on the top of the preparation shell, a grinding wheel is sleeved in the first bearing, and a plurality of second bearings are clamped on the surface of the grinding wheel, an extrusion roller is sleeved in the second bearing, 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 a discharge port is arranged at the bottom of the preparation shell.

[0004] Permeable bricks made from waste materials are unfired bricks, that is, they do not need to go through a high-temperature sintering process. This type of permeable brick is formed by a press and then hardened and solidified through a curing process. After the solid waste is put into the above-mentioned device, the solid waste is first ground, and then adhesives and other ingredients are added after grinding, and then stirred and pressed to obtain permeable bricks. Since solid waste may contain metal impurities such as iron wire and iron nails, the presence of these impurities can easily block the pores inside the permeable bricks, reduce the permeable area, and affect the permeable effect. 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: In the first aspect, the present application provides a device for preparing permeable bricks using waste concrete, which adopts the following technical solution: A device for preparing permeable bricks using waste concrete comprises a box body and a magnetic separation component arranged in the box body, wherein the magnetic separation component comprises a rotating power part, a turntable, a guide frame and a magnetic plate, wherein the turntable is coaxially fixedly connected to the output end of the rotating power part, the axis of the turntable is arranged along the height direction of the box body, the guide frame is fixedly connected to the inner wall of the box body, the guide frame is located at the top of the turntable and abuts against the top wall of the turntable, the guide frame is arranged in a spiral shape coaxial with the turntable, a drop opening is opened at the center of the turntable, a feed opening is arranged at the top of the box body, and the feed opening is located at the top of the edge of the turntable, so that when the turntable rotates, the material falling onto the turntable through the feed opening moves along the guide frame and falls from the drop opening, the magnetic plate is arranged on the inner wall of the box body and located at the top of the guide frame, and the magnetic plate is used to adsorb metal impurities in the material.

[0007] 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 rotation of the turntable 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.

[0008] 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 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.

[0009] 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 that the magnetic plate adsorbs too much metal impurities and affects the adsorption effect of the magnetic plate.

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 metal impurities on the receiving plate fall into the collection frame.

[0011] 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 member can cause the receiving plate to rotate downward, thereby causing the metal impurities on the receiving plate to fall into the collection frame; 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, thereby facilitating the receiving of the metal impurities that accidentally fall from the magnetic plate in the next stroke.

[0012] 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 adjusting member for driving the abutment plate to slide is provided between the abutment plate and the box body.

[0013] By adopting the above technical solution, the cooperation of the first magnetic part and the second magnetic part can make the abutment plate stay at the current position when it slides to any position; the adjusting component can adjust the position of the abutment plate, so that when the scraper slides to 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 to 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 prevent the metal impurities on the magnetic plate from being accidentally pushed down during the process of the scraper sliding to the side away from the collection frame.

[0014] 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 collecting frame, the first mounting block is provided with a first inclined surface, the second mounting block is provided with a second inclined surface, and a third mounting block is fixedly connected to the abutment plate, and the third mounting block is provided with a third inclined surface, 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.

[0015] By adopting the above technical solution, when the scraper slides to the side away from the collecting 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 collecting 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.

[0016] Optionally, a wind separation component is provided in the box body, 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 body, and the air outlet of the blower faces into the box body. A separation port for removing lighter materials is opened on the side wall of the box body, and a accommodating cavity for accommodating heavier materials is provided at the bottom of the box body.

[0017] By adopting the above technical solution, light impurities such as wood, paper, plastic, etc. in waste concrete can be separated under the action of wind, thereby enhancing the impurity removal effect on waste concrete.

[0018] Optionally, a guide plate is fixedly connected to the box body, the guide plate is located on a 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.

[0019] 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 they fall, allowing the raw materials to be more fully in contact with the wind and enhancing the separation effect.

[0020] Optionally, a vibration mechanism is provided in the box, and the vibration mechanism includes a wind force piece, a guide shell, a knocking piece and a first ventilation pipe. The wind force piece is rotatably provided in the box, and the rotation axis of the wind force piece is provided along the height direction of the box. The guide shell is fixedly connected to the bottom wall of the turntable, and one end of the knocking piece is slidably provided in the guide shell along the height direction of the box. The first ventilation pipe is fixedly connected to the box, 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 piece, so that the blower drives the wind force piece to rotate, and the wind force piece intermittently resists against the knocking piece, and causes the knocking piece to intermittently hit the turntable.

[0021] 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 striking piece can slide back and forth in the vertical direction, so that the top of the striking piece intermittently knocks on the turntable, causing the turntable to vibrate, so that the raw materials on the turntable are more dispersed, and the metal impurities in the raw materials are more easily adsorbed by the magnetic plate, thereby enhancing the separation effect; because the sliding of the striking 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.

[0022] 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.

[0023] By adopting the above technical solution, the cooperation between the fourth inclined surface and the hemispherical end makes it easier to drive the knocking piece to slide when the wind force piece rotates, which helps the knocking piece to slide smoothly.

[0024] In a second aspect, the present application provides a process for preparing permeable bricks, using the following technical solution: A process, using any of the above-mentioned devices for preparing permeable bricks, comprises the following steps: a. Crushing the waste concrete; b. Screen the crushed materials to obtain particles of the required size; c. The screened material falls onto the turntable through the feed port on the box body. 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. d. Add the required raw materials to the materials after impurities are removed and mix them; e. Pressing the mixed raw materials into permeable bricks of the required shape; f. Cure the permeable bricks for a period of time and dry them after curing.

[0025] By adopting the above technical scheme, the waste concrete can be mixed with other raw materials after being crushed, screened and impurity-removed in sequence, and then pressed. Finally, it can be made into permeable bricks through curing and drying, so that the waste concrete is fully utilized and the utilization rate of resources is improved.

[0026] In summary, the present application includes at least one of the following beneficial technical effects: 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 mixed 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 permeable effect of the subsequently formed permeable bricks.

[0027] 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.

[0028] 3. When the blower is working, the wind force part can be rotated, so that the knocking part can intermittently slide up and down, and 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

[0031] The following is combined with Figure 1-7 This application is described in further detail.

[0032] The embodiment of the present application discloses a device for preparing permeable bricks using waste concrete, comprising a crushing mechanism, a screening mechanism, a debris removal mechanism, a mixing mechanism and a pressing mechanism which are arranged in sequence.

[0033] 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.

[0034] Reference Figure 1 and Figure 2 The impurity removal mechanism includes a box 1 and a magnetic separation component 2. The box 1 is vertically arranged. A feed port 11 is provided on the top of the box 1. The raw materials after crushing and screening can be fed into the box 1 through the feed port 11 for magnetic separation. The magnetic separation component 2 is arranged in the box 1 and can absorb metal impurities in the raw materials. The raw materials after magnetic separation fall to the bottom of the box 1.

[0035] Reference Figure 3 and Figure 4 , the 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 housing 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 housing 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 end of the output shaft of the rotating power part 21 is coaxially fixedly connected to a 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 disposed above the rotating power member 21 , so that the material falling from the drop opening 221 can be shielded to prevent the material from falling directly onto the rotating power member 21 , thereby helping to ensure the normal operation of the rotating power member 21 .

[0036] The guide frame 23 is fixedly connected to the inner wall of the box body 1, and the guide frame 23 is located above the turntable 22; the guide frame 23 is in a spiral shape coaxially arranged with the turntable 22, and the bottom wall of the guide frame 23 and the top wall of the turntable 22 are against each other; one end of the guide frame 23 is located at the edge of the outer side 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 box body 1 is located just above the edge of the turntable 22, so after the waste concrete raw material is put into the inner side of the box body 1 through the feed opening 11, the raw material falls to the edge just above the turntable 22; the rotating power part 21 drives the turntable 22 to rotate when working, and the turntable 22 can drive the raw material to rotate when rotating. Since the guide frame 23 is fixedly arranged, under the restriction of the guide frame 23, the raw material will move along the guide frame 23 when rotating, and the raw material will gradually move from the edge of the turntable 22 to the center of the turntable 22, and then fall from the drop opening 221 on the turntable 22.

[0037] The magnetic separation component 2 also includes a magnetic plate 24, which is fixedly connected to the inner wall of the box body 1 and is arranged horizontally; the magnetic plate 24 is a rectangular plate, and the magnetic plate 24 is arranged at intervals just above the guide frame 23. The bottom surface of the magnetic plate 24 is magnetic, so it can absorb metal. Therefore, when the raw material moves along the spiral track, the metal in the raw material will be absorbed on the bottom surface of the magnetic plate 24, thereby separating the metal impurities in the raw material.

[0038] Reference Figure 4 , a cleaning assembly 3 is also provided on the box body 1, and the cleaning assembly 3 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, and the power telescopic member 31 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 horizontally arranged. 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; therefore, 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 accidentally falling from the magnetic plate 24 during the sliding process of the scraper 32. The collecting frame 34 is fixedly connected to the side wall of the box body 1, and is located at one end of the magnetic plate 24, and the collecting frame 34 is located below the magnetic plate 24, and the opening of the collecting frame 34 faces upward. Therefore, the metal impurities adsorbed on the bottom wall of the magnetic plate 24 can be pushed into the collecting frame 34 by the scraper 32, so that the metal impurities can be collected.

[0039] Reference Figure 5The scraper 32 includes a mounting frame 321 and an abutment plate 322. The mounting frame 321 is fixedly connected to the end of the piston rod of the power telescopic member 31, and the length direction of the mounting frame 321 is horizontally arranged; a slide groove 3211 is provided at the top of the mounting frame 321 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 component 3212 is clamped and fixed on the inner wall of the slide groove 3211, and a second magnetic component 3221 is clamped and fixed on the outer wall of one end of the abutment plate 322 located in the slide groove 3211. The first magnetic component 3212 and the second magnetic component 3221 are both magnets, and the first magnetic component 3212 and the second magnetic component 3221 are in contact with each other; the magnetic poles of the first magnetic component 3212 and the second magnetic component 3221 are in opposite directions on one side close to each other, so the first magnetic component 3212 and the second magnetic component 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.

[0040] Reference Figure 6 and Figure 7 , the box body 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 box body 1, and the first mounting block 41 and the second mounting block 42 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 is provided with a first inclined surface 411 on the side close to the collection frame 34, and the second mounting block 42 is provided with 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 with a third mounting block 43, and the two ends of the third mounting block 43 are provided with 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 inclination degree; and the height of the second mounting block 42 is higher than the height of the first mounting block 41.

[0041] 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, so that the metal impurities adsorbed on the magnetic plate 24 can be scraped off. In 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, and then as the mounting frame 321 slides, the abutting plate 322 slides downward while sliding horizontally, so that the abutting plate 322 slides 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 down, it drives the third mounting block 43 to slide down, so that the third mounting block 43 slides to the same height as the first mounting block 41.

[0042] Then the piston rod end of the power telescopic member 31 is retracted, so that the mounting frame 321 drives the abutment plate 322 to slide to 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, and 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. Then the piston rod end of the power telescopic member 31 slides back and forth, so that the scraper 32 can slide back and forth, thereby cleaning the metal impurities adhering to the magnetic plate 24.

[0043] Reference Figure 6 In order to facilitate the emptying 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, and the hinge axis of the receiving plate 33 is arranged along the length direction of the mounting frame 321. The inner wall of the box body 1 is fixedly connected with a limit rod 14, and the limit rod 14 is arranged along the sliding direction of the piston rod of the power telescopic member 31. The limit rod 14 is arranged below the magnetic plate 24 at intervals; under normal conditions, the receiving plate 33 is arranged horizontally, and the bottom wall of the receiving plate 33 and the top wall of the limit rod 14 are against each other. 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.

[0044] Reference Figure 5Furthermore, 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 enables the receiving plate 33 to press against the limiting rod 14. Therefore, the setting of the elastic member 5 enables the receiving plate 33 to rotate downward more easily when the mounting frame 321 moves to one end close to the collecting frame 34.

[0045] After crushing, screening and magnetic separation, waste concrete mainly includes 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, sawdust and plastic mixed in it. In order to separate these light impurities, refer to Figure 2 , a wind separation assembly is arranged in the box 1, and the wind separation assembly includes a blower 6, the blower 6 is fixedly connected to the outer wall of the box 1, and the air outlet of the blower 6 is connected to a second ventilation pipe 61, and the end of the second ventilation pipe 61 away from the blower 6 is located in the box 1; the end of the second ventilation pipe 61 located in the box 1 is located below the turntable 22, and the end of the second ventilation pipe 61 located in the box 1 is inclined upward. A separation port 12 is provided on the side wall of the box 1 away from the blower 6, and the separation port 12 is located below the turntable 22; and a receiving chamber 13 is arranged at the bottom of the box 1. Therefore, after the blower 6 is started, the box 1 can be blown, and when the raw materials are magnetically separated, they fall from the drop port 221 on the turntable 22. After the falling raw materials are blown by the wind, the lighter impurities in the raw materials are discharged through the separation port 12, and the heavier materials in the raw materials fall into the receiving chamber 13 at the bottom of the box 1, which is convenient for subsequent mixing.

[0046] Reference Figure 3 Furthermore, 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 a conical surface shape 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 down 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 falling raw materials, allowing the raw materials and the wind blown by the blower 6 to be more fully in contact, which helps to enhance the separation effect of the raw materials.

[0047] A vibration mechanism 8 is also provided in the box body 1, and the vibration mechanism 8 includes a wind force member 81, a guide shell 82, a knocking member 83 and a first ventilation pipe 84. The wind force member 81 includes a mounting ring 811 and a wind shield 812. The mounting ring 811 and the turntable 22 are coaxially arranged, and the mounting ring 811 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, so that the raw materials on the turntable 22 fall smoothly. The wind shield 812 is fixedly connected to the bottom wall of the mounting ring 811, and there are multiple wind shields 812, which are arranged in a circular array; the wind shield 812 is arranged in a hemispherical shell 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 outer side 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 opened on the ring rail 15. The guide block 8111 is slidably engaged in the guide groove 151, so that the mounting ring 811 is rotatably arranged on the inner side of the ring rail 15.

[0048] The guide shell 82 is 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 arranged at intervals, and each group of guide shells 82 is arranged in a circular array; the height direction of the guide shell 82 is arranged vertically. There are multiple knocking pieces 83, and the number is the same as the number of guide shells 82. Each knocking piece 83 is arranged in a guide shell 82; the knocking piece 83 is cylindrical, and the knocking piece 83 is slidably arranged in the guide shell 82 along the vertical direction. The top of the knocking piece 83 can contact the bottom wall of the turntable 22. Under normal conditions, the top of the knocking piece 83 and the bottom wall of the turntable 22 are arranged at intervals; the bottom end of the knocking piece 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, and the push block 9 is located below the knocking piece 83; there are multiple push blocks 9, and the number is the same as the number of knocking pieces 83, and each push block 9 corresponds to a knocking piece 83.

[0049] The first ventilation pipe 84 is fixedly connected to the outer wall of the box body 1, 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 set and faces the wind shield 812. Therefore, after the blower 6 is started, a part of the wind 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 can drive 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 is separated from the abutment with the knocking member 83, so that the knocking member 83 can reciprocate 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, so that the turntable 22 vibrates, so that 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.

[0050] 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.

[0051] The fourth inclined surface 91 is disposed on both sides of the top of the push block 9, and the bottom end of the knocking piece 83 is configured as a hemisphere, so the cooperation between the fourth inclined surface 91 and the hemisphere can make it easier to push the knocking piece 83 to slide when the push block 9 rotates. A rubber pad is also bonded to the top of the knocking piece 83, so that the possibility of the push block 9 being stuck can be reduced in the process of the push block 9 pushing the knocking piece 83 to slide.

[0052] The implementation principle of the device for preparing permeable bricks using waste concrete in the embodiment of the present application is as follows: the waste concrete raw materials first enter the crushing mechanism for crushing; the crushed raw materials fall into the screening mechanism, and the particles with smaller sizes are screened out for subsequent molding; then the screened raw materials enter the box body 1 through the feed port 11 on the box body 1, and fall to the edge of the top surface of the turntable 22, and the rotating power part 21 starts to drive the turntable 22 to rotate, and the turntable 22 drives the raw materials on the top surface of the turntable 22 to rotate when the turntable 22 rotates. Under the restriction of the guide frame 23, the raw materials on the turntable 22 move 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 materials, the magnetic plate 24 absorbs the metal impurities in the raw materials, thereby removing the metal impurities in the raw materials. After the impurities are removed, the raw materials fall through the drop port 221 in the center of the turntable 22, and the raw materials first fall to the top surface of the guide plate 7, and then the raw materials fall through the discharge holes 71 on the guide plate 7 and the bottom end of the guide plate 7. Under the action of the wind blown by the blower 6, the light impurities in the raw materials are blown away through the separation port 12, and the heavier materials in the raw materials fall into the receiving chamber 13 at the bottom of the box body 1. Then the raw materials in the receiving chamber 13 are sent to the mixing mechanism, and other raw materials and water are added to mix. The mixed raw materials are sent to the pressing mechanism to be pressed into the required permeable bricks. Finally, the permeable bricks are taken out and cured and dried.

[0053] During the magnetic separation process in the box 1, in the initial state, the bottom surfaces of the abutting plate 322 and the magnetic plate 24 are abutted against each other, the receiving plate 33 is in a horizontal state, and the bottom surface of the receiving plate 33 and the top of the limiting rod 14 are abutted against each other; then the piston rod of the power telescopic member 31 extends, so that the mounting frame 321 drives the abutting plate 322 to slide toward the side close to the collection frame 34, and the abutting plate 322 pushes the metal impurities adsorbed on the magnetic plate 24 to move, and pushes the metal impurities on the magnetic plate 24 into the collection frame 34; during the sliding process of the abutting plate 322, the receiving plate 33 can receive the metal impurities accidentally dropped from the magnetic plate 24. When the abutting plate 322 moves to the side close to the collection frame 34, due to the loss of the support of the limiting rod 14, the elastic member 5 causes the receiving plate 33 to rotate downward, so that the metal impurities on the receiving plate 33 will 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 breaks away from contact with the magnetic plate 24.

[0054] Then the piston rod of the power telescopic member 31 is retracted again, so that the installation frame 321 and the abutment plate 322 move to the side away from the collection frame 34. During the movement, since the abutment plate 322 and the magnetic plate 24 are not in contact, the metal impurities adsorbed on the magnetic plate 24 will not be affected. When the installation 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, and then as the installation frame 321 moves, the abutment plate 322 moves upward while sliding horizontally 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 cleans the metal impurities adsorbed on the magnetic plate 24 into the collection frame 34, ensuring the adsorption effect of the magnetic plate 24.

[0055] 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, so that the knocking piece 83 moves 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, further enhancing the adsorption effect of the magnetic plate 24.

[0056] The present application also discloses a process for preparing a water-permeable brick, comprising the following steps: a. Put the waste concrete into the crushing mechanism for crushing; b. Transport the crushed raw materials to the screening mechanism to screen out particles of the required size; 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; d. The blower 6 blows air into the box body 1, and the raw materials falling from the material drop opening 221 are separated under the action of wind force, and the 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; e. The raw materials in the containing chamber 13 are transported to the mixing mechanism, and other required raw materials and water are added and stirred and mixed; f. Transport the mixed raw materials to the pressing mechanism to press out the required permeable bricks; g. Take out the permeable bricks, maintain them for a period of time, and then dry them after maintenance.

[0057] The above are optional embodiments of the present application, and are not intended to limit the protection scope 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 protection scope of the present application.
