Description

Technical Field

[0001] The invention relates to the technical field of concrete crushing, and in particular to production crushing equipment and a crushing process of an aerated concrete plate. Background Art

[0002] Aerated concrete board is the full name of autoclaved aerated concrete board. Aerated concrete board is a lightweight, porous, new green and environmentally friendly building material that uses cement, lime, silica sand and other materials as the main raw materials and adds different amounts of anti-corrosion treated steel mesh according to structural requirements. It is produced through high temperature and high pressure, steam curing, and reaction to produce porous crystal sand aerated concrete boards. Its density is smaller than that of general cement materials, and it has excellent fire resistance, fire prevention, sound insulation, heat insulation, and thermal insulation. It is widely used in production and life.

[0003] After the concrete slabs are discarded, they need to be crushed when they are recycled and reused. The existing crushing methods are mostly heavy hammering or shearing crushing. During the shearing crushing, the steel bars embedded in the slabs are easily damaged when they are crushed, and the crushed stones and dust are often discharged together, which makes it difficult to take them separately, and it is easy to cause dust when taking the stones. Therefore, we proposed a production and crushing equipment for aerated concrete slabs and its crushing process. Summary of the invention

[0004] In order to solve the above technical problems, the present invention provides a production and crushing equipment for aerated concrete panels and a crushing process thereof, comprising:

[0005] A shell, the shell is used to store the crushed materials, and the outside of the shell is provided with supporting legs;

[0006] A crushing mechanism, which has a crushing structure and is used to crush materials;

[0007] The outer surface of the shell is fixedly connected to the inner side of the leg, and the crushing mechanism is fixedly connected to the inner wall of the shell;

[0008] Wherein, the crushing mechanism comprises:

[0009] The hopper is in a shape of being larger at the top and smaller at the bottom, and is used to contain the materials to be crushed and after being crushed;

[0010] A roller body, the surface of which is arranged in a tooth shape, and the tooth-shaped notches of the roller body are spirally distributed, so as to quickly crush the edge of the material, and a rotating shaft is arranged inside the roller body;

[0011] A transmission assembly, which is used to drive the roller to rotate;

[0012] A blocking component, which has a symmetrical arc structure and is used to block smoke and dust generated by crushing;

[0013] A material discharge component, the material discharge component has a screening structure for screening out dust generated after material crushing;

[0014] The inner wall of the roller body is fixedly connected to the surface of the rotating shaft, the two ends of the rotating shaft extend to the outside of the hopper, and the surface of the rotating shaft is rotatably connected to the inner wall of the hopper, the outer surface of the hopper is fixedly connected to the inner wall of the shell, the outer side of the transmission assembly is fixedly connected to the inner wall of the shell, and the output end of the transmission assembly is fixedly connected to the end of the rotating shaft, the blocking assembly is arranged directly above the roller body, and the blocking assembly is fixedly connected to the inside of the hopper, the feeding assembly is arranged directly below the roller body, and the feeding assembly is fixedly connected to the inside of the shell, the material is put into the hopper from the top, and contacts the roller body under the action of its own gravity, the transmission assembly drives the rotating shaft to rotate, drives the roller body to rotate, the roller body contacts the edge of the material, quickly crushes the material, and then leaves the hopper and enters the feeding assembly inside the shell, the feeding assembly screens the crushed material, separates stone and powder The teeth are not separated, which is convenient for subsequent production. The surface of the roller is set to be tooth-shaped. The tooth-shaped structure has multiple crushing positions. The material can be crushed multiple times during one rotation, and the tooth-shaped gaps are spirally distributed. The spirally distributed tooth-shaped gaps, when in contact with the material, in addition to generating vertical pressure, can also exert other components on the material. During crushing, the component force twists and squeezes the material, thereby achieving a better crushing effect through torsion and crushing the material more quickly. For the spirally distributed tooth-shaped gaps, at the same time, there is always only one tooth in contact with the material, which reduces the contact area and increases the crushing pressure. During the crushing process, the teeth contact the material in turn, and the material is gradually crushed, further improving the crushing effect. By increasing the crushing pressure and gradually crushing, the crushing difficulty is reduced, so that the roller can be efficiently crushed and not easily damaged.

[0015] Furthermore, the number of the roller bodies is two, and the two roller bodies are both arranged at the bottom of the hopper, the two roller bodies are meshed with each other, and the inner walls of the two roller bodies are fixedly connected with a rotating shaft. By symmetrically arranging the roller bodies, the meshing part of the two roller bodies is in a concave state, and the material enters the concave part after falling, which can ensure that the material is located at the meshing part of the two roller bodies, thereby achieving extrusion and crushing on both sides of the material, and doubling the crushing effect. The roller body is made of a grooved roller surface. Compared with a single part fixed on the surface of the rotating shaft for crushing, its integrity means that the connection strength is higher, and it is not easy to be damaged by steel bars embedded in the material, which can effectively improve the service life.

[0016] Furthermore, the transmission assembly includes a motor, which is arranged at the gap between the outer shell and the hopper, and the outer surface of the motor is fixedly connected to the inner wall of the outer shell, the side of the motor away from the inner wall of the outer shell is fixedly connected to the rotating shaft, and the end surface of the rotating shaft is fixedly connected to the output end of the motor, and the ends of the two rotating shafts away from the motor are fixedly connected with gears, and the two gears are meshed with each other, and the motor is started, and the output end of the motor drives the rotating shaft to rotate, and the rotating shaft rotates, driving a roller body and a gear to rotate, and then the gear drives another gear meshed with it to rotate, driving another rotating shaft and a roller body to rotate, thereby realizing the crushing of materials by the two rollers, and the gear meshing connection makes the two rollers rotate in opposite directions, so that the material can be transported to the bottom of the hopper, and clamped while being crushed to prevent the material from rolling on the surface of the roller body, thereby achieving a better crushing effect.

[0017] Furthermore, tooth plates are provided on the sides of the two roller bodies that are away from each other, and the sides of the two tooth plates that are away from each other are fixedly connected to the inner wall of the hopper, and the sides of the two tooth plates that are close to each other are set to a tooth shape, and the sides of the two tooth plates that are close to each other are respectively meshed with the two roller bodies, the roller body rotates, and the tooth plates are stationary, thereby generating relative motion. When the roller body rotates, the meshing part is cleared and cleaned to prevent steel bars and the like from getting stuck on the surface of the roller body, to prevent the two roller bodies from getting stuck, and to clean stones stuck in the roller body to prevent the groove of the roller body from becoming shallower, thereby obtaining a better crushing effect.

[0018] Furthermore, the blocking assembly includes baffles, which are symmetrically arranged inside the hopper, and the sides of the two baffles close to each other are bent downward toward the roller body, and the sides of the two baffles away from each other are fixedly connected to the inner wall of the hopper, and a corrugated groove is provided on the side of the baffle away from the roller body. When placing materials, the materials pass through the interval between the two baffles, and the smaller concrete slab is directly crushed by contacting the baffle with the roller body, and the longer concrete slab is crushed by contacting the roller body on one side and resting on the surface of the baffle on the other side. The baffle provides support for the concrete slab to prevent the larger concrete slab from being placed horizontally inside the hopper, ensuring the contact between the concrete slab and the roller body, and the setting of the bent baffle can block the smoke and dust generated during crushing, avoid dust generated during the crushing process, and avoid dust blocking the workers' sight, thereby avoiding danger caused by the workers' sight being blocked, and by providing the corrugated groove, the friction between the contact surface of the baffle and the concrete slab is increased, thereby preventing the concrete slab from slipping, and the corrugated groove with a corrugated setting can provide greater resistance in all directions, and prevent the concrete slab from warping or deflecting when the concrete slab is crushed and torsionally crushed by the roller body.

[0019] Furthermore, the inner wall of the hopper is fixedly connected with a rotating seat, and the rotating seat is symmetrically arranged on a side where the two baffles are away from each other, and the side of the rotating seat away from the inner wall of the hopper is rotatably connected with a rotating plate, the side of the rotating plate away from the rotating seat is fixedly connected to the side of the baffle away from the other baffle, and the number of the rotating plates is set to be several. When the baffle provides support, the baffle deforms and drives the rotating plate to rotate around the rotating seat, thereby changing the interval between the two baffles to adapt to concrete slabs of different sizes and support and limit concrete slabs of different thicknesses to facilitate their crushing. The side of the rotating plate away from the baffle is fixedly connected with an elastic rod, one end of the elastic rod away from the rotating plate is fixedly connected to the side of the rotating seat away from the baffle, and the elastic rod is set to be several corresponding to the number of rotating plates. When the rotating plate rotates around the rotating seat, the elastic rod is driven to deform, and under the elastic force of the elastic rod restoring the deformation, the elastic rod supports the bottom of the baffle, thereby cooperating with the baffle to support the concrete slab.

[0020] Furthermore, the unloading assembly includes a unloading plate, which is inclined inside the shell and extends to the outside of the shell, and the unloading plate is arranged directly below the roller body, and the surface of the unloading plate is fixedly connected to the inner wall of the shell, and baffle plates are symmetrically arranged on both sides of the unloading plate, and the baffle plates are arranged outside the shell, and the two baffle plates are fixedly connected to the outer surface of the shell, and the crushed material enters the bottom of the shell, and finally falls to the surface of the unloading plate, and leaves the shell along the unloading plate. The inclined unloading plate allows the material to roll along the surface of the unloading plate under the action of gravity, ensuring that the crushed material can completely leave the inside of the shell, avoiding the accumulation of material at the bottom of the shell, and when rolling, the dust on the surface of the crushed material can be shaken off, thereby achieving a certain separation effect.

[0021] Furthermore, a rectangular groove is provided on the discharge plate just below the hopper, a sieve plate is provided on one side of the discharge plate close to the hopper, and the surface of the sieve plate is slidably connected to the inner wall of the rectangular groove, sieve holes are provided on the surface of the sieve plate, the sieve holes are arranged in an elliptical shape, and a plurality of sieve holes are evenly distributed on the surface of the sieve plate, a lower ash cylinder is fixedly connected on the side of the shell away from the hopper, and the inner wall of the lower ash cylinder is arranged in a cone shape, and the crushed material falls onto the surface of the sieve plate, and is separated from the dust by impacting the sieve plate, and then the material rolls on the surface of the sieve plate, and the dust enters the lower ash cylinder through the sieve holes, and finally accumulates at the bottom of the shell through the lower ash cylinder, and at the same time, the stones roll onto the surface of the discharge plate and finally leave the shell, Thereby, the stones and dust are separated and the two are piled separately to facilitate their separate use in subsequent processing. By setting an inclined screen plate, the dust is separated once when the material collides with the screen plate, and then a secondary separation is performed when the material rolls on the inclined surface, thereby improving the stripping effect of the dust on the surface of the stone and achieving more efficient separation. The screen holes are set to an elliptical shape. The elliptical screen holes have a larger surface area and a smaller interval. The larger surface area can avoid blockage, and the smaller interval can ensure the screening effect. The inner wall of the lower ash barrel is set to a cone. The conical inner wall can gather the dust. The overall mass of the gathered dust is larger, and it can fall in piles when leaving the inside of the outer shell to avoid being engulfed by natural wind, thereby reducing dust.

[0022] Furthermore, springs are symmetrically arranged on one side of the sieve plate close to the lower ash cylinder, and the springs are fixedly connected to the side of the sieve plate close to the lower ash cylinder. The ends of the two springs away from the sieve plate are fixedly connected to a plate body, and the sides of the two plate bodies away from each other are fixedly connected to the inner wall of the rectangular groove. When the sieve plate is hit, the sieve plate moves, driving the springs to compress, thereby acting as a buffer to avoid damage to the sieve plate caused by the impact. Subsequently, under the elastic force of the springs to restore their deformation, the sieve plate is driven to reset, thereby driving the sieve plate to vibrate up and down. The springs are only arranged at both ends, and the sieve plate is inclined, so that the sieve plate can also shake up and down alternately at both ends, thereby ensuring the complete separation of stones and dust.

[0023] The dust removal assembly includes a rubber cylinder, which is configured to be conical, and a side of the rubber cylinder away from the lower ash cylinder is fixedly connected to a side of the screen plate close to the lower ash cylinder, the rubber cylinder is arranged outside the sieve hole, and the rubber cylinder is arranged corresponding to the number of sieve holes, a tube body is arranged on the side of each row of the rubber cylinder away from the sieve plate, and the surface of the tube body is fixedly connected to the side of each row of the rubber cylinder away from the sieve plate, a dust removal plate is fixedly connected to the side of the tube body away from the rubber cylinder, a pump body is arranged inside the lower ash cylinder, an ash inlet pipe is fixedly connected to the side of the pump body close to the sieve plate, one end of the ash inlet pipe is sealed, and an ash discharge pipe is fixedly connected to the side of the pump body away from the ash inlet pipe, the surface of the ash discharge pipe is fixedly connected to the inner side surface of the lower ash cylinder, and the rubber cylinder, tube body, dust removal plate, ash inlet pipe, pump body and ash discharge The inner cavity of the pipe is connected, and the pump body is started. The air passes through the rubber cylinder, pipe body, dust removal plate, ash inlet pipe, pump body in turn, and is finally discharged through the ash discharge pipe. The dust in the air enters the rubber cylinder with the circulating air, and is finally discharged from the ash discharge pipe, completing the separation of dust and stones. The dust can be quickly sucked in through the adsorption of the circulating airflow to avoid the generation of dust. With the vibration of the screen plate, the rubber cylinder is deformed. The rubber cylinder can avoid affecting the vibration of the screen plate and ensure the screening effect. The suction force is generated inside the sieve hole, which can attract the stones on the top of the screen plate, thereby reducing the rolling speed of the stones, thereby extending the screening time and ensuring the complete screening of the dust. It can extend the screening time without affecting the vibration screening and ensure the screening effect. The dust can be completely adsorbed to effectively avoid the generation of dust.

[0024] A crushing process of a production crushing equipment for aerated concrete panels, comprising the following steps:

[0025] S1. Concrete loading: When placing materials, the materials pass through the gap between the two baffles. The smaller concrete slab directly contacts the roller body through the baffle to be crushed. One side of the longer concrete slab contacts the roller body to be crushed, and the other side rests on the surface of the baffle. The baffle provides support for the concrete slab to prevent the larger concrete slab from being placed horizontally inside the hopper, ensuring the contact between the concrete slab and the roller body.

[0026] S2, material crushing, start the motor, the output end of the motor drives the shaft to rotate, the shaft rotates, drives a roller and a gear to rotate, then the gear drives another gear meshing with it to rotate, drives another shaft and roller to rotate, the roller contacts the edge of the material, and the material is quickly crushed;

[0027] S3, vibration separation, the crushed material enters the bottom of the shell, falls to the surface of the screen plate, hits the screen plate, the screen plate is hit, the screen plate moves, drives the spring to compress, and then under the elastic force of the spring to restore the deformation, drives the screen plate to reset, thereby driving the screen plate to vibrate up and down. The springs are only set at both ends, and the screen plate is tilted, so the screen plate produces staggered up and down shaking at both ends. The irregular shaking completely separates the stones and dust;

[0028] S4, material discharge, crushed material and dust are separated, then the material rolls on the surface of the screen plate, the dust enters the lower ash cylinder through the screen hole, and finally accumulates at the bottom of the shell through the lower ash cylinder, at the same time, the stone rolls to the surface of the discharge plate, and finally leaves the shell, thus completing the separation of stone and dust, and the two are accumulated separately;

[0029] S5, dust adsorption, start the pump body, the air passes through the rubber cylinder, the tube body, the dust removal plate, the ash inlet pipe, the pump body in turn, and is finally discharged through the ash discharge pipe. The dust in the air enters the rubber cylinder with the circulating air and is finally discharged from the ash discharge pipe, completing the separation of dust and stones.

[0030] The present invention has the beneficial effects:

[0031] The present invention provides a crushing mechanism, and the surface of the roller body is set to be tooth-shaped. The tooth-shaped structure has multiple crushing positions, and the material can be crushed multiple times during one rotation process, and the tooth-shaped gaps are spirally distributed. When the spirally distributed tooth-shaped gaps come into contact with the material, in addition to generating vertical pressure, they can also exert another component force on the material. During crushing, the component force twists and squeezes the material, thereby achieving a better crushing effect through torsion and crushing the material more quickly. For the spirally distributed tooth-shaped gaps, only one tooth shape is in contact with the material at the same time, and the crushing pressure is increased by reducing the contact area. During the crushing process, the teeth come into contact with the material in turn, and the material is gradually crushed, further improving the crushing effect. By increasing the crushing pressure and gradually crushing, the crushing difficulty is reduced, so that the roller body is efficiently crushed and not easily damaged.

[0032] The present invention arranges the roller bodies symmetrically, and the meshing parts of the two roller bodies are in a concave state. After the material falls, it enters the concave part, which can ensure that the material is located at the meshing part of the two roller bodies, thereby achieving extrusion and crushing of both sides of the material, and doubling the crushing effect. The roller body is made of a grooved roller surface. Compared with a single part fixed on the surface of the rotating shaft for crushing, its integrity means that the connection strength is higher, and it is not easy to be damaged by steel bars embedded in the material, etc., which can effectively improve the service life.

[0033] The present invention provides a blocking mechanism, and the baffle provides support for the concrete slab, so as to prevent a larger concrete slab from being placed horizontally inside the hopper, thereby ensuring the contact between the concrete slab and the roller body. The setting of the curved baffle can block the smoke and dust generated during crushing, avoid the generation of dust during the crushing process, and avoid the dust blocking the workers' vision, thereby avoiding the danger caused by the workers' vision being blocked. By providing a corrugated groove, the friction between the contact surface of the baffle and the concrete slab is increased, thereby preventing the concrete slab from slipping. The corrugated groove of the corrugated setting can provide greater resistance in all directions, and when the concrete slab is crushed and torsionally crushed by the roller body, the concrete slab is prevented from warping or deflecting.

[0034] The present invention provides a feeding mechanism and an inclined screen plate. When the material collides with the screen plate, the dust is separated once. Subsequently, when the material rolls on the inclined surface, a secondary separation is performed, thereby improving the stripping effect of the dust on the surface of the stone and achieving more efficient separation. The screen holes are set to an elliptical shape. The elliptical screen holes have a larger surface area and a smaller interval. The larger surface area can avoid blockage, and the smaller interval can ensure the screening effect. The inner wall of the lower ash barrel is set to a cone shape. The conical inner wall can gather the dust. The overall mass of the gathered dust is larger and can fall in piles when leaving the inside of the shell to avoid being swept away by natural wind, thereby reducing dust. The screen plate is hit and moves, driving the spring to compress and drive the screen plate to vibrate up and down. The spring is only set at two ends, and the screen plate is inclined, so that the two ends of the screen plate can also shake up and down alternately, thereby ensuring the complete separation of stones and dust.

[0035] The present invention is provided with a dust removal component, which can quickly suck in dust through the adsorption of circulating airflow to avoid the generation of dust. As the screen plate vibrates, the rubber cylinder is deformed, and the rubber cylinder can avoid affecting the vibration of the screen plate to ensure the screening effect. The screen hole generates suction to attract the stones on the top of the screen plate, thereby reducing the rolling speed of the stones, thereby extending the screening time and ensuring the complete screening of the dust. The screening time can be extended without affecting the vibration screening to ensure the screening effect, and the dust can be completely adsorbed to effectively avoid the generation of dust.

Provide support to prevent larger concrete slabs from being placed horizontally inside the hopper 31, ensure the contact between the concrete slab and the roller body 32, and the setting of the curved baffle 341 can block the smoke and dust generated during crushing, avoid the generation of dust during the crushing process, and avoid the dust blocking the workers' vision, thereby avoiding the danger caused by the workers' vision being blocked. By providing the corrugated groove 342, the friction between the contact surface of the baffle 341 and the concrete slab is increased, thereby preventing the concrete slab from slipping, and the corrugated groove 342 with a corrugated setting can provide greater resistance in all directions, and when the concrete slab is crushed and torsionally crushed by the roller body 32, the concrete slab is prevented from warping or deflecting.

[0064] The inner wall of the hopper 31 is fixedly connected with a rotating seat 343, and the rotating seat 343 is symmetrically arranged on the side where the two baffles 341 are away from each other. The side of the rotating seat 343 away from the inner wall of the hopper 31 is rotatably connected with a rotating plate 344, and the side of the rotating plate 344 away from the rotating seat 343 is fixedly connected to the side of the baffle 341 away from the other baffle 341, and the number of rotating plates 344 is set to be several. When the baffle 341 provides support, the baffle 341 is deformed, driving the rotating plate 344 to rotate around the rotating seat 343, thereby changing the interval between the two baffles 341 to adapt to concrete slabs of different sizes. Concrete slabs of different thicknesses can be supported and limited to facilitate their crushing. A spring rod 345 is fixedly connected to the side of the rotating plate 344 away from the baffle 341. One end of the spring rod 345 away from the rotating plate 344 is fixedly connected to the side of the rotating seat 343 away from the baffle 341, and a number of spring rods 345 are arranged corresponding to the number of rotating plates 344. When the rotating plate 344 rotates around the rotating seat 343, the spring rod 345 is driven to deform. Under the elastic force of the spring rod 345 to restore the deformation, the spring rod 345 supports the bottom of the baffle 341, thereby cooperating with the baffle 341 to support the concrete slab.

The crushed materials enter the bottom of the shell 1 and eventually fall onto the surface of the unloading plate 351 and leave the shell 1 along the unloading plate 351. The inclined unloading plate 351 allows the materials to roll along the surface of the unloading plate 351 under the action of gravity, ensuring that the crushed materials can completely leave the inside of the shell 1 and avoid accumulation of materials at the bottom of the shell 1. When rolling, the dust on the surface of the crushed materials can be shaken off, thereby achieving a certain separation effect.

By setting an inclined screen plate 354, the dust is separated once when the material collides with the screen plate 354, and then a secondary separation is performed when the material rolls on the inclined surface, thereby improving the stripping effect of the dust on the surface of the stone and achieving more efficient separation. The sieve holes 355 are set to an elliptical shape. The elliptical sieve holes 355 have a larger surface area and a smaller interval. The larger surface area can avoid blockage, and the smaller interval can ensure the screening effect. The inner wall of the lower ash cylinder 353 is set to a cone. The conical inner wall can gather the dust. The overall mass of the gathered dust is large, and it can fall in piles when leaving the inside of the outer shell 1 to avoid being swept away by natural wind, thereby reducing dust.

[0067] Springs 357 are symmetrically provided on one side of the sieve plate 354 close to the lower ash cylinder 353, and the springs 357 are fixedly connected to the side of the sieve plate 354 close to the lower ash cylinder 353.

Subsequently, under the elastic force of the springs 357 to restore the deformation, the sieve plate 354 is driven to reset, thereby driving the sieve plate 354 to vibrate up and down, and the springs 357 are only provided at both ends, and the sieve plate 354 is inclined, so that the sieve plate 354 can also shake up and down alternately at both ends, thereby ensuring the complete separation of stones and dust.

[0068] The dust removal assembly 38 includes a rubber cylinder 381, which is set in a conical shape. The side of the rubber cylinder 381 away from the lower ash cylinder 353 is fixedly connected to the side of the sieve plate 354 close to the lower ash cylinder 353.

The air passes through the rubber cylinder 381, the pipe body 383, the dust removal plate 382, ​​the ash inlet pipe 384, the pump body 385 in sequence, and is finally discharged through the ash discharge pipe 386. The dust in the air enters the rubber cylinder 381 with the circulating air, and is finally discharged from the ash discharge pipe 386, completing the separation of dust and stones. The dust can be quickly inhaled through the adsorption of the circulating airflow to avoid the generation of dust. The vibration of plate 354 causes the rubber cylinder 381 to deform. The rubber cylinder 381 can avoid affecting the vibration of the screen plate 354 and ensure the screening effect. The suction force generated inside the screen hole 355 can attract the stones on the top of the screen plate 354, thereby reducing the rolling speed of the stones, thereby extending the screening time and ensuring complete screening of the dust. It can extend the screening time without affecting the vibration screening, ensure the screening effect, and completely absorb the dust, effectively avoiding the generation of dust.
