A recycled concrete mixing apparatus and a sampling method thereof

Abstract

This invention discloses a convenient sampling device for recycled concrete mixing, comprising a base, a main body, and a sampling port. The main body is mounted on top of the base, and the sampling port is formed through the outer side of the main body. A sealing plate is fitted into the inner side of the chute. A fixing frame is mounted on the outer side of the main body. A connecting seat is mounted on the output end of an electric telescopic rod three, and a sampling cylinder is mounted on the output end of a cylinder. This invention, by installing a fixing frame on the outer side of the main body, allows the electric telescopic rod three to push the connecting seat through the sampling port into the main body. When the sampling cylinder is inside the main body, the cylinder pushes the sampling cylinder downwards to sample the newly mixed concrete. The electric telescopic rod four then moves a pusher plate downwards to push the sampled concrete in the sampling cylinder. This automatic sampling avoids the impact of manual sampling on the production efficiency of recycled concrete.

Description

Technical Field

[0001] This invention relates to the field of recycled concrete processing technology, specifically to a convenient recycled concrete mixing equipment and sampling method. Background Technology

[0002] Recycled concrete is typically made by crushing, cleaning, and grading waste concrete blocks, then mixing them with aggregates in a certain proportion to partially or completely replace natural aggregates such as sand and gravel. Cement and water are then added to form new concrete. During the preparation of new concrete, it is necessary to ensure that the recycled concrete aggregates and natural aggregates are fully mixed to ensure the consistent performance of the new concrete.

[0003] The shortcomings of existing concrete mixing equipment are:

[0004] 1. Patent document CN211250746U discloses a recycled concrete mixing equipment, "including a frame, a mixing chamber fixed on the frame, a feeding port at the upper end of the mixing chamber, and an aggregate opening and closing device at the lower end; a mixing mechanism is installed on the mixing chamber, the mixing mechanism includes a mixing shaft horizontally rotatably installed in the mixing chamber, multiple sets of mixing components evenly distributed along the axial direction of the mixing shaft, and a power motor driving the mixing shaft to rotate; the mixing components include a first mixing paddle and a second mixing paddle, the first mixing paddle includes a connecting rod radially distributed along the mixing shaft and a first mixing blade fixed to the end of the connecting rod, the second mixing paddle includes a fixed rod radially distributed along the mixing shaft and a second mixing blade fixed to the end of the fixed rod, the length of the connecting rod is greater than the length of the fixed rod, and the first and second mixing paddles of each set of mixing components are staggered on the outer circumference of the mixing shaft. The recycled concrete mixing equipment of this utility model can force mixing and improve the mixing degree of new and old aggregates." This mixing equipment cannot crush the concrete raw materials, the large particle size of the raw materials reduces the mixing efficiency of recycled concrete, and cannot guarantee the production quality of recycled concrete.

[0005] 2. Patent document CN216543967U discloses a recycled concrete mixing device. "This utility model includes a mixing box and a collection box. The mixing box is a box structure. Several servo motors are installed on one surface of the mixing box. The motor shafts of the servo motors are fixedly connected to output shafts. Crushing wheels are installed on the periphery of the output shafts, with two crushing wheels positioned symmetrically. Filter screens are fixedly installed on opposite surfaces inside the mixing box, with the filter screens angled. An opening is provided on one side of the mixing box. This utility model uses servo motors to drive the crushing wheels to rotate via the output shafts, facilitating the crushing of large concrete blocks inside the mixing box, thus improving the mixing effect of various materials. Smaller concrete blocks fall from the filter screens, while larger concrete blocks slide out through the opening along the filter screens, facilitating further crushing and improving the crushing effect of the concrete blocks, thereby improving the mixing effect of various materials." However, this mixing device cannot automatically feed large mixed soil blocks, increasing the labor intensity of workers. The collection box lacks a monitoring function, making it easy for concrete blocks to exceed the maximum load capacity of the collection box, causing damage.

[0006] 3. Patent document CN213617497U discloses a recycled concrete mixer, "including a mixing drum, the bottom of which is supported by a fixed frame. Inside the mixing drum, from top to bottom, are arranged a compaction mechanism, a lifting mechanism, a mixing mechanism, and a dust removal mechanism. The dust removal mechanism includes a vent pipe connected to one side below the mixing drum. A filter screen is vertically inserted into the end of the vent pipe near the mixing drum, and the end away from the mixing drum is connected to a collection box fixedly connected to the fixed frame. A fan is connected to the end of the collection box away from the vent pipe. This invention, through the dust removal mechanism, can collect the dust inside the mixing drum, preventing dust from scattering into the air during material feeding, thus avoiding air pollution and harm to surrounding workers, making the concrete recycling working environment safer and cleaner." However, this concrete mixer lacks a sampling port, making it impossible to sample and inspect the materials mixed inside, and thus failing to guarantee the mixing quality of the recycled concrete.

[0007] 4. Patent document CN218342470U discloses a recycled concrete mixing device, "including a mixing tank, a rotating motor installed on the mixing tank, a rotating shaft installed inside the mixing tank, a hexagonal block fixed at the bottom of the rotating shaft, and a bottom block installed on the mixing tank. This recycled concrete mixing device, by pouring material into the inside of a discharge pipe fixedly connected to the top of the mixing tank, the rotating motor rotates, at which point the hexagonal block is located inside a hexagonal block groove, and the rotating motor drives the hexagonal block to rotate inside the hexagonal block groove. The bottom of the rotating column rotates on the top of the bottom plate, and the rotating rod, driven by the rotating column, stirs the material inside the mixing tank. At this time, a scraper cleans the inner wall of the mixing tank, thereby reducing waste and ensuring uniform mixing of the material inside the mixing tank." This concrete mixing device cannot automatically sample the mixed concrete inside the mixing tank; manual sampling reduces the production efficiency of recycled concrete and cannot guarantee the accuracy of the sampling results.

[0011] Preferably, a filter frame is symmetrically installed on the inner wall of the main body of the equipment, an electric telescopic rod is symmetrically installed on the inner wall of the filter frame, a sliding block is installed at the output end of the electric telescopic rod, a buffer spring is provided on the outer side of the electric telescopic rod, a connecting sleeve is installed on the inner side of the sliding block, and a filter screen is installed on the opposite side of the connecting sleeve.

[0012] Preferably, a movable groove is provided on the inner wall of the sampling port, and the movable groove cooperates with the sealing plate. An installation groove is provided on the inner wall of the other side of the sampling port. An electric telescopic rod II is installed on the inner side of the installation groove. A collection port is provided through the top of the fixed frame, and the sampling tube passes through the inner side of the collection port. An electric telescopic rod IV is installed on the inner side of the top of the sampling tube, and a pusher plate is installed at the output end of the electric telescopic rod IV.

[0013] Preferably, the fixing frame is matched with the sampling port, the output shaft of the transmission motor is connected to the input end of the crushing roller II via a pulley, the other end of the buffer spring is connected to the outside of the sliding block, and the output end of the electric telescopic rod II is connected to the outside of the sealing plate.

[0014] Preferably, a fixing plate is installed on the inner wall of the main body of the equipment, a material discharge port is opened through the top of the fixing plate, a second motor is installed on the top of the fixing plate, a rotating rod is installed at the output end of the second motor, and a stirring blade is installed on the outside of the rotating rod.

[0015] Preferably, a feeding rack is installed on the top of the base, a partition is installed on the inner wall of the feeding rack, a motor is installed on the top of the partition, a threaded rod is installed on the inner side of the feeding rack, and the output end of the motor is connected to the input end of the threaded rod. A lifting block is installed on the outer side of the threaded rod. A limit frame is installed on the top of the base, a limit groove is provided on the inner wall of the limit frame, a limit block is fitted inside the limit groove, and an electric rotating seat is installed on the opposite side of the limit block and the lifting block.

[0016] Preferably, the output end of the electric rotating seat is equipped with a collection box, the inner wall of the collection box is provided with a moving groove, the inner side of the moving groove is fitted with a bottom plate, a weighing sensor is installed on the bottom wall of the collection box, and the output end of the weighing sensor is connected to the bottom of the bottom plate, and a collection frame is installed on the top of the bottom plate.

[0017] Preferably, the operating steps of this recycled concrete mixing equipment are as follows:

[0018] S1. First, the concrete mixture enters the main body of the equipment through the feed cylinder. The drive motor drives the first crushing roller to rotate. The second crushing roller rotates synchronously in the opposite direction to the first crushing roller under the drive of the belt pulley to initially crush the concrete mixture. The first motor drives the crushing rod to rotate so that the crushing teeth further crush the initially crushed concrete mixture. The concrete mixture becomes granular and falls downward.

[0019] S2. After being filtered through a screen, concrete mixing raw material particles that meet the mixing requirements fall from the discharge port to the bottom of the equipment body. When the electric telescopic rod is working, it pushes the sliding block to reciprocate in the vertical direction. The buffer spring buffers the impact force when the sliding block reciprocates. The operation of the screen frame causes the screen to vibrate up and down, causing the mixed raw material particles on the screen surface to fall downwards, preventing the mixed raw material particles from clogging the screen. Large mixed raw material particles that do not meet the mixing requirements accumulate on the screen surface and are discharged through the slag discharge port along the inclined direction of the screen.

[0020] S3. Drive the pump to extract mixed water from the outside. The mixed water enters the main body of the equipment through the inlet via the pipeline. The second motor drives the rotating rod to rotate. The rotation of the rotating rod causes the stirring blade to mix the raw materials evenly. After stirring for a period of time, the second electric telescopic rod pushes the outer side of the sealing plate. The sealing plate slides inside the chute and is stored inside the movable groove, thus removing the sealing plate from the sampling port.

[0021] S4. The electric telescopic rod pushes the connecting seat through the inside of the sampling port to move into the main body of the equipment. When the sampling cylinder is inside the main body of the equipment, the cylinder works to push the sampling cylinder downward to sample the new concrete after mixing. After the new concrete is sampled, the sampling cylinder is reset.

[0022] Preferably, step S2 further includes the following steps:

[0023] S21. The collection frame collects the discharged large-particle mixed raw materials. Due to the weight of the large-particle mixed raw materials in the collection frame, the bottom plate moves inside the moving trough to squeeze the weighing sensor. The weighing sensor works to detect the weight of the large-particle mixed raw materials in the collection frame.

[0024] S22. When the collection box meets the maximum load capacity, the motor runs and drives the threaded rod to rotate. The rotation of the threaded rod causes the lifting block to move the collection box in the vertical direction. The limiting block slides inside the limiting groove under the transmission action. When the collection box is above the feeding cylinder, the electric rotating seat works to put large particle mixed raw materials into the main body of the equipment for secondary crushing.

[0025] Step S4 further includes the following steps:

[0026] S41. The electric telescopic rod drives the pusher plate downward to push the sampled concrete in the sampling cylinder. The sampled concrete falls into the designated collection container through the collection port. The staff observes and tests its quality. When the production quality meets the standard, the new concrete after mixing is discharged through the discharge pipe.

[0027] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0028] 1. This invention features crushing teeth installed on the outside of a crushing rod. A drive motor rotates a first crushing roller, while a second crushing roller rotates synchronously in the opposite direction to the first crushing roller under the transmission of a pulley, initially crushing the concrete mixture. The first motor then rotates the crushing rod, causing the crushing teeth to further crush the initially crushed concrete mixture. The concrete mixture becomes granular and falls downwards. The screen frame vibrates up and down, causing the mixture particles on the screen surface to fall downwards, preventing the mixture particles from clogging the screen. This prevents large particles from adversely affecting the mixing efficiency of recycled concrete and ensures the production quality of recycled concrete.

[0029] 2. This invention features a collection box installed at the output end of the electric rotating seat. The collection box collects large-particle mixed raw materials. Due to the weight of the large-particle mixed raw materials in the collection box, the bottom plate moves within the moving groove to compress the weighing sensor. When the collection box meets the maximum load capacity, the electric motor drives the threaded rod to rotate. The rotation of the threaded rod causes the lifting block to move the collection box vertically. The limiting block slides within the limiting groove under the transmission action. When the collection box is above the feeding cylinder, the electric rotating seat operates to feed the large-particle mixed raw materials into the main body of the equipment for secondary crushing. The automatic feeding of large mixed soil blocks reduces the labor intensity of the workers and ensures the good performance of the collection box.

[0030] 3. This invention features a sampling port that penetrates the outer side of the main body of the equipment. Mixed water enters the main body of the equipment through a pipe and inlet. The second motor drives the rotating rod to rotate, which causes the mixing blades to uniformly mix the raw materials. After mixing for a period of time, the second electric telescopic rod pushes the outer side of the sealing plate. The sealing plate slides inside the chute and is stored inside the movable groove, removing the obstruction of the sampling port. The automatic opening and closing of the sampling port facilitates sampling and inspection of the mixed materials inside the main body of the equipment, ensuring the mixing quality of the recycled concrete.

[0031] 4. This invention features a fixed frame installed on the outside of the main body of the equipment. An electric telescopic rod pushes the connecting seat through the inner side of the sampling port into the main body of the equipment. When the sampling cylinder is inside the main body of the equipment, a cylinder pushes the sampling cylinder downwards to sample the mixed new concrete. After sampling, the sampling cylinder resets, and the electric telescopic rod moves the pusher plate downwards to push the sampled concrete inside the sampling cylinder. The sampled concrete falls through the collection port into a designated collection container, where workers observe and test its quality. This automatic sampling of the mixed concrete inside the main body of the equipment avoids the impact of manual sampling on the production efficiency of recycled concrete and ensures the accuracy of the sampling results.

A threaded rod 43 is installed on the inner side of the feeding rack 7, and the output end of the motor 42 is connected to the input end of the threaded rod 43.

The weighing sensor 51 detects the weight of the raw materials in the collection frame 52 in real time.

[0051] The working steps of this recycled concrete mixing equipment are as follows:

[0052] S1. First, the concrete mixture enters the main body 2 of the equipment through the feed cylinder 12. The drive motor 11 drives the first crushing roller 9 to rotate. The second crushing roller 10 rotates synchronously in the opposite direction with the first crushing roller 9 under the transmission of the belt pulley to perform preliminary crushing of the concrete mixture. The first motor 13 drives the crushing rod 14 to rotate so that the crushing teeth 15 further crush the pre-crushed concrete mixture. The concrete mixture becomes granular and falls downward.

[0053] S2. Concrete mixture particles that meet the mixing requirements are filtered through screen 24 and fall from discharge port 25 to the bottom of the inner side of the main body 2. The electric telescopic rod 20 drives the sliding block 22 to reciprocate in the vertical direction. The buffer spring 21 buffers the impact force when the sliding block 22 reciprocates. The operation of the screen frame 3 drives the screen 24 to vibrate up and down, causing the mixed raw material particles on the surface of the screen 24 to fall downwards, preventing the mixed raw material particles from clogging the screen 24. Large mixed raw material particles that do not meet the mixing requirements accumulate on the surface of the screen 24 and are discharged through the slag discharge port 16 along the inclined direction of the screen 24.

[0054] S3, drive pump 19 to draw mixed water from the outside. The mixed water enters the equipment body 2 through the inlet 17 via the pipeline. Motor 26 drives the rotating rod 27 to rotate. The rotating rod 27 rotates so that the stirring blade 28 can evenly mix the mixed raw materials. After stirring for a period of time, the electric telescopic rod 33 pushes the outer side of the sealing plate 30. The sealing plate 30 slides inside the slide groove 29 and is stored inside the movable groove 31, thus removing the obstruction and protection of the sampling port 5 by the sealing plate 30.

[0055] S4. The electric telescopic rod 34 works to push the connecting seat 35 through the inner side of the sampling port 5 and move into the equipment body 2. When the sampling cylinder 37 is inside the equipment body 2, the cylinder 36 works to push the sampling cylinder 37 downward to sample the new concrete after mixing. After the new concrete is sampled, the sampling cylinder 37 is reset.

[0056] Step S2 also includes the following steps:

[0057] S21, the collection frame 52 collects the discharged large particle mixed raw materials. Due to the weight of the large particle mixed raw materials in the collection frame 52, the bottom plate 50 moves inside the moving groove 49 to squeeze the weighing sensor 51. The weighing sensor 51 works to detect the weight of the large particle mixed raw materials in the collection frame 52.

[0058] S22. When the collection frame 52 meets the maximum load capacity, the motor 3 42 runs and drives the threaded rod 43 to rotate. The rotation of the threaded rod 43 causes the lifting block 44 to move the collection box 8 in the vertical direction. The limiting block 47 slides inside the limiting groove 46 under the transmission action. When the collection box 8 is above the feeding cylinder 12, the electric rotating seat 48 works to put large particle mixed raw materials into the equipment body 2 for secondary crushing.

[0059] Step S4 also includes the following steps:

[0060] S41, the electric telescopic rod 39 drives the pusher plate 40 to move downwards, pushing the sampled concrete in the sampling cylinder 37. The sampled concrete falls into the designated collection container through the collection port 38. The staff observes and tests its quality. When the production quality meets the standard, the new concrete after mixing is discharged through the discharge pipe 18.

[0061] Working principle: When using this device, the concrete mixture first enters the main body 2 of the equipment through the feed cylinder 12. The drive motor 11 drives the first crushing roller 9 to rotate. The second crushing roller 10 rotates synchronously in the opposite direction to the first crushing roller 9 under the transmission of the belt pulley, which initially crushes the concrete mixture. The first motor 13 drives the crushing rod 14 to rotate, which causes the crushing teeth 15 to further crush the initially crushed concrete mixture. The concrete mixture becomes granular and falls downward. The concrete mixture particles that meet the mixing requirements are filtered through the screen 24 and fall from the discharge port 25 to the bottom of the inner side of the main body 2. The electric telescopic rod 20 drives the sliding block 22 to reciprocate in the vertical direction, slowly... The spring 21 buffers the impact force of the sliding block 22 during reciprocating movement. The operation of the screen frame 3 drives the screen 24 to vibrate up and down, causing the mixed raw material particles on the surface of the screen 24 to fall downwards, preventing the mixed raw material particles from clogging the screen 24. Large mixed raw material particles that do not meet the mixing requirements accumulate on the surface of the screen 24 and are discharged through the slag outlet 16 along the inclined direction of the screen 24. The collection frame 52 collects the discharged large mixed raw material particles. Due to the weight of the large mixed raw material particles in the collection frame 52, the bottom plate 50 moves inside the moving groove 49 to squeeze the weighing sensor 51. The weighing sensor 51 works to detect the weight of the large mixed raw material particles in the collection frame 52. When the collection frame 52 meets the maximum load capacity... When the electric motor 42 operates, it drives the threaded rod 43 to rotate. The rotation of the threaded rod 43 causes the lifting block 44 to move the collection box 8 vertically. Under the transmission action, the limiting block 47 slides inside the limiting groove 46. When the collection box 8 is above the feed cylinder 12, the electric rotating seat 48 operates to feed large particles of mixed raw materials into the main body 2 of the equipment for secondary crushing. The driving pump 19 operates to extract mixed water from the outside. The mixed water enters the main body 2 of the equipment through the pipe and the water inlet 17. The electric motor 26 operates, driving the rotating rod 27 to rotate. The rotation of the rotating rod 27 causes the stirring blade 28 to uniformly mix and stir the mixed raw materials. After stirring for a period of time, the electric telescopic rod 33 operates to push the outer side of the sealing plate 30. The sampler slides inside the chute 29 and is stored inside the movable groove 31. The sealing plate 30 removes the obstruction and protection of the sampling port 5. The electric telescopic rod 34 pushes the connecting seat 35 through the inside of the sampling port 5 and moves it into the equipment body 2. When the sampling cylinder 37 is inside the equipment body 2, the cylinder 36 pushes the sampling cylinder 37 downward to sample the new concrete after mixing. After the new concrete is sampled, the sampling cylinder 37 is reset. The electric telescopic rod 49 drives the pusher plate 40 downward to push the sampled concrete in the sampling cylinder 37. The sampled concrete falls into the designated collection container through the collection port 38. The staff observes and tests its quality. When the production quality meets the standard, the new concrete after mixing is discharged through the discharge pipe 18.
