Description

Technical Field

[0001] This invention relates to the field of concrete processing technology, and in particular to a processing apparatus and method for crack-resistant commercial concrete. Background Technology

[0002] The process of preparing ready-mixed concrete typically begins with raw material storage. Cement, sand, gravel, and mineral admixtures are stored in dedicated silos, with levels monitored by level gauges. Admixtures and water are stored in sealed tanks. During production, the control system instructs metering equipment to accurately weigh each raw material according to a preset mix proportion. Sand and gravel are conveyed by belt conveyors, while cement and admixtures are conveyed by screw conveyors. Admixtures and water are quantitatively injected through pumps. After all raw materials enter the mixer, they are mixed according to a set program. First, dry mixing is used to ensure the solid raw materials are evenly mixed, and then water and admixtures are added for wet mixing. Admixtures can optimize the workability of concrete, adjust setting time, and improve durability. Common types include water-reducing agents, accelerators, retarders, air-entraining agents, and expanding agents. Water-reducing agents can reduce the amount of mixing water and improve the strength and fluidity of concrete; early-strength agents accelerate hardening and are suitable for low-temperature construction; retarders extend the setting time and facilitate long-distance transportation; air-entraining agents introduce micro-bubbles to enhance frost resistance; and expanding agents offset shrinkage through volume expansion, reducing cracks until homogeneous concrete is formed. After mixing, the concrete enters the transport tanker through the unloading port. The tanker rotates at a low speed during transportation to prevent segregation. Upon arrival at the construction site, the slump and other indicators must be tested again before unloading. Only after passing the test can the concrete be used for pouring. The entire process is controlled by an automated system to ensure continuous and stable production.

[0003] The existing publication number is CN110757614B. This application relates to a concrete processing equipment in the field of building material processing technology. It mainly consists of a vibrating table, a mold, push rods, a pressure plate assembly, a release agent spray pipe, and a conveyor belt. The mold and pressure plate assembly are both mounted on the vibrating table. The mold is composed of a bottom mold box and partitions. The bottom mold box includes a bottom template and side panels located on both sides of the long side of the bottom template. The bottom template has openings on both sides of the short side and at the top. Several notches are provided on the side panels, and several partitions that mate with the notches are provided at both ends of the side panels. The notches on the two side panels are staggered, with the partitions on the same side facing the notches on the same side. The partitions and side panels form several sequentially arranged mold cavities, and the partitions on the same side are fixedly connected to the same rotating shaft. This application sets the mold to consist of a bottom mold box with multiple notches and multiple partitions. The multiple partitions and two side panels form multiple sequentially arranged mold cavities, avoiding the need for multiple molds.

[0004] However, in the existing ready-mixed concrete mixing process, workers need to manually sample and test the slump after mixing. When taking samples manually, the continuous operation of the mixing equipment needs to be interrupted. After receiving the concrete sample from the mixer's discharge port, workers complete the operations of molding, compaction, lifting the drum, and measurement in the testing area. The operation is quite cumbersome. If the test finds that the slump does not meet the standard, the mixing equipment needs to be restarted to add raw materials, and the mixing and testing need to be repeated, which affects the processing efficiency of ready-mixed concrete. Summary of the Invention

[0005] In view of this, the present invention provides a processing apparatus and method for crack-resistant ready-mixed concrete, which enables the intermittent addition of a mixed expansive fiber crack-resistant agent, avoiding the problem of uneven dispersion caused by a large one-time addition. This allows the crack-resistant agent to be evenly distributed in the concrete, effectively improving the crack resistance and overall quality of the ready-mixed concrete. It also achieves screening of the crack-resistant agent, preventing clumps of the agent from being added to the concrete, further ensuring the purity of the raw materials. Furthermore, it automates sampling and testing during the mixing process, replacing manual sampling, tamping, and measurement, reducing human intervention, minimizing testing errors caused by differences in operating techniques, and improving testing accuracy. Sampling and testing can be completed without interrupting the mixing equipment, eliminating equipment downtime during manual sampling. The testing process is continuous and efficient, significantly shortening the time required for a single test, avoiding production delays caused by repeated adjustments due to insufficient slump, improving the processing efficiency of ready-mixed concrete, and providing a clear view of the initial and final concrete height data. This allows workers to quickly determine whether the slump meets the standard, providing a precise basis for subsequent raw material adjustments, ensuring concrete quality while avoiding excessive adjustments that could damage the mix proportions, further optimizing the production process.

[0015] Beneficial effects

[0016] This invention utilizes an intermittent feeding mechanism. An intermittent adding motor is activated, and through a transmission gear, it drives an intermittent drive pin to rotate. This rotation of the intermittent drive pin drives an intermittent drive grooved wheel, which in turn drives an intermittent adding roller. The intermittent transmission function of the grooved wheel structure causes the intermittent adding roller to rotate intermittently. When the opening of the intermittent adding roller faces upwards, the mixed expandable fiber crack-resistant agent from the admixture addition box enters the inner side of the roller. When the opening of the roller faces downwards, the mixed expandable fiber crack-resistant agent is added to the interior of the mixer body. This intermittent addition of the mixed expandable fiber crack-resistant agent avoids the uneven dispersion problem caused by a large-scale one-time addition, ensuring the crack-resistant agent is evenly distributed in the concrete and effectively improving the crack resistance and overall quality of the ready-mixed concrete.

[0017] This invention utilizes an intermittent feeding mechanism. When the screening motor is turned on, the output shaft of the screening motor rotates, which in turn drives the screening drive wheel to rotate. The rotation of the screening drive wheel causes the screening drive component to move back and forth, which in turn causes the screening filter screen to move back and forth. This movement of the screening filter screen achieves the screening of crack-resistant agents, preventing clumps of crack-resistant agents from being added to the concrete and further ensuring the purity of the raw materials.

[0018] This invention utilizes a sampling and testing mechanism. When the testing lifting mechanism is activated, its piston rod moves downwards, causing the sampling cylinder to move downwards. This downward movement aligns the testing drive groove with the sampling guide pipe, bringing the lower end of the sampling cylinder into contact with the testing base plate. At this point, concrete from inside the mixer enters the sampling cylinder. Then, the testing vibrator is activated, and its piston rod moves up and down, causing the tamping rod to move up and down, thus tamping the concrete. The height of the concrete is counted using a laser rangefinder. The piston rod of the testing lifting mechanism then moves upwards, causing the sampling cylinder to move upwards, emptying the concrete. After a period of time, the concrete height is counted again using the laser rangefinder. Workers observe the height of the concrete as measured. The digital display records the initial and final height of the concrete, automating sampling and testing during the mixing process. It replaces manual sampling, tamping, and measurement, reducing human intervention, minimizing errors caused by variations in operating techniques, and improving accuracy. Sampling and testing can be completed without interrupting the mixing equipment, eliminating downtime during manual sampling. The testing process is seamless and efficient, significantly shortening the time required for each test and avoiding production delays caused by repeated adjustments due to insufficient slump. This improves the efficiency of ready-mixed concrete processing, providing a clear view of the initial and final height data, allowing workers to quickly determine if the slump meets the standard. This provides a precise basis for subsequent raw material adjustments, ensuring concrete quality while avoiding excessive adjustments that could disrupt the mix design, further optimizing the production process.

[0040] The specific usage and function of this embodiment are as follows: When processing ready-mixed concrete, the feeding drive 103 is opened, and the piston rod of the feeding drive 103 moves inward to pull the feeding transmission rod 102. The feeding transmission rod 102 drives the feeding baffle 101 to flip open.

[0041] Example 2:

[0042] like Figures 1 to 8 As shown:

[0043] The present invention provides a processing device and method for crack-resistant commercial concrete. Based on the first embodiment, it further includes a sampling and testing mechanism, which is located on the left side of the mixer body 1.

[0044] The sampling and testing mechanism includes: a testing lifting component 601, a testing sampling cylinder 602, and a testing drive groove 603; the testing lifting component 601 is a hydraulic cylinder structure, and the testing lifting component 601 is fixedly connected to the upper left side of the mixer body 1; the testing sampling cylinder 602 is fixedly connected to the lower end of the piston rod of the testing lifting component 601, and the right side of the testing sampling cylinder 602 is in frictional contact with the sampling guide pipe 7, and the inner wall of the testing sampling cylinder 602 is coated with an interface agent; the testing drive groove 603 is opened on the upper right side of the testing sampling cylinder 602.

[0045] The sampling and testing mechanism also includes: a testing vibratory element 604, a testing tamping rod 605, and a testing base plate 606; the testing vibratory element 604 is a reciprocating hydraulic cylinder structure, and the testing vibratory element 604 is fixedly connected to the upper left side of the mixer body 1; the testing tamping rod 605 is fixedly connected to the lower end of the piston rod of the testing vibratory element 604; the testing base plate 606 is fixedly connected to the lower left side of the mixer body 1, and the upper surface of the testing base plate 606 is coated with an interface agent.

[0047] The specific usage and function of this embodiment are as follows: After mixing the ready-mixed concrete for a period of time, the detection lifting component 601 is opened. The piston rod of the detection lifting component 601 moves downward, causing the detection sampling cylinder 602 to move downward.

The lower end of the detection sampling cylinder 602 contacts the detection base plate 606. At this time, the concrete inside the mixer body 1 enters the interior of the detection sampling cylinder 602. The detection vibrator 604 is opened.

The worker records the initial and final height of the concrete by observing the distance measurement digital display 6, thereby realizing the measurement of the concrete slump. This automates the sampling and testing during the mixing process, replacing manual sampling, tamping, and measurement, reducing human intervention, reducing detection errors caused by differences in operating techniques, and improving detection accuracy. Sampling and testing can be completed without interrupting the operation of the mixing equipment, saving the equipment downtime waiting time during manual sampling. The testing process is continuous and efficient, significantly shortening the time for a single test, avoiding production delays caused by repeated adjustments due to substandard slump, and improving the processing efficiency of ready-mixed concrete.

9. The processing apparatus for crack-resistant commercial concrete as described in claim 8, characterized in that: The sampling and testing mechanism also includes a laser rangefinder (607); the laser rangefinder (607) is fixedly connected to the upper left side of the mixer body (1), and the laser rangefinder (607) is connected to the signal input terminal of the rangefinder digital display (6) through a wire.

10. The processing method of crack-resistant commercial concrete as described in claim 1, characterized in that: S1. Cement and aggregates (sand, gravel, etc.) are loaded into cement addition box (3) and aggregate addition box (4) respectively. The admixture addition box (5) is pre-filled with mixed expansion fiber anti-cracking agent. After the device is started, the feeding drive component (103) drives the feeding baffle (101) to flip and open, so that the raw materials in cement addition box (3) and aggregate addition box (4) fall into the main body of mixer (1) according to the set amount. At the same time, the mixing drive motor (2) drives the mixing shaft through the gearbox to start the initial mixing of the raw materials. S2. During the raw material mixing process, the intermittent addition mechanism is started simultaneously to add mixed expanded fiber anti-cracking agent. The intermittent addition motor (106) is driven by the addition transmission gear (107) to drive the intermittent drive pin (108) to rotate. The intermittent addition roller (105) is rotated intermittently by the grooved wheel structure (intermittent drive pin (108) and intermittent drive grooved wheel (109)). When the opening of the intermittent addition roller (105) is facing upward, the anti-cracking agent falls from the admixture addition box (5) into the intermittent addition roller (105). When the opening is facing downward, the anti-cracking agent enters the mixer body (1) through the intermittent support seat (104). The intermittent addition ensures that the anti-cracking agent is evenly dispersed. At the same time, the screening motor (110) drives the screening drive wheel (111) to rotate. The screening filter screen (112) is driven to slide back and forth by the crank slider structure (screening drive wheel (111) and screening drive component (113)) to screen the falling anti-cracking agent. S3. The raw materials and crack-resistant agent are continuously stirred in the main body of the mixer (1) to form a uniform mixture. After stirring for a period of time, the sampling and testing mechanism is started to perform slump testing. The testing lifting component (601) drives the testing sampling cylinder (602) to move down, so that the testing drive groove (603) is aligned with the sampling guide pipe (7). The concrete enters the testing sampling cylinder (602) through the sampling guide pipe (7). At the same time, the testing vibrator (604) drives the testing tamping rod (605) to tamp up and down to ensure that the sample is compacted. The laser rangefinder (607) records the initial height of the concrete at this time. The slump is transmitted to the distance measuring digital display (6), and then the detection lifting component (601) drives the detection sampling cylinder (602) to move upward. The concrete collapses on the detection base plate (606). After a period of time, the laser distance measuring instrument (607) records the final height again. The worker reads the data through the distance measuring digital display (6) and calculates the slump to determine whether the workability of the concrete meets the standard. If the slump meets the requirements, the concrete after mixing can be directly unloaded to the transportation equipment. If it does not meet the standard, the amount of raw materials or crack-resistant agent added is adjusted through the control system, and the concrete is remixed and tested again until it meets the standard.
