Description

Technical Field

[0001] This invention relates to the field of concrete processing technology, and more particularly to a concrete processing apparatus for construction engineering. Background Technology

[0002] In construction engineering, the uniformity of mixing viscous materials such as concrete directly affects product performance. However, current mainstream mixing equipment has significant technical shortcomings and struggles to meet industrial requirements:

[0003] First, the mixing mechanism has limitations. Viscous materials have high cohesion and poor fluidity. Traditional equipment relies on single radial rotational shearing, which makes it difficult to break up micro-agglomerates such as cement particles. Furthermore, it cannot solve the problem of axial stratification between coarse aggregate and cement paste, which easily leads to "macroscopic uniformity but microscopic heterogeneity" or "aggregate accumulation at the bottom". This results in product strength deviations exceeding ±10%, requiring a mixing time extension of more than 30%, and significantly increasing energy consumption.

[0004] Secondly, the structural coordination is poor. The functions of stirring, scraping, and airflow disturbance are mostly driven independently. Fixed or independent scrapers are difficult to clean the wall and bottom of the material at the same time, requiring manual cleaning. The continuous fixed inflation mode is not adaptable enough, and there is no coordination between airflow and mechanical stirring. When the material is dense, the airflow is difficult to penetrate, and when it is loose, it is easy to escape, resulting in limited disturbance effect.

[0005] Third, the contradiction between efficiency and cost is prominent. Multiple power sources increase total energy consumption by 20%-30%, and the component failure rate is 15%-20% higher in high dust environments, resulting in high maintenance costs.

[0006] In summary, existing equipment struggles to balance high uniformity, low energy consumption, and high reliability, necessitating structural innovation to achieve a multi-functional and synergistic mixing solution. Summary of the Invention

[0007] The purpose of this invention is to address the shortcomings of existing technologies by proposing a concrete processing device for construction engineering.

[0008] To achieve the above objectives, the present invention adopts the following technical solution:

[0009] A concrete processing apparatus for construction engineering, comprising:

[0010] A mixing hopper is used for carrying and mixing concrete materials.

[0011] A top support plate is set above the mixing hopper. Several sets of connecting bent rods are evenly arranged on the upper outer side of the mixing hopper. The connecting bent rods are fixedly connected to the top support plate. A push rod motor is installed at the top center of the top support plate.

[0012] The mixing assembly, located inside the mixing hopper, includes an air guide tube coaxially fixed at the axis of the mixing hopper. This tube provides stable support for the mixing process and conducts airflow to improve the uniformity of mixing. A bottom scraper assembly is rotatably fitted onto the lower outer side of the air guide tube to cover and scrape the inner wall of the bottom of the mixing hopper, preventing material adhesion. Two sets of vertical mixing components are fitted onto the upper outer side of the air guide tube. These components effectively mix materials. The lower vertical mixing component works in a spiral drive with the bottom scraper assembly. A connecting rod connects the two sets of vertical mixing components, and a top connecting component is connected to the top of each component. This top connecting component is coaxially connected to the output shaft of a push rod motor. The push rod motor then effectively moves the vertical mixing components up and down, facilitating effective mixing of materials. The vertical movement of the mixing components also allows the bottom scraper assembly to work in a spiral action, effectively scraping the inner wall of the mixing hopper and preventing material adhesion.

[0013] As a preferred technical solution of this application, the vertical stirring assembly includes a scraper ring frame, a connecting screen plate is installed on the inner side of the scraper ring frame, a central shaft sleeve is fixedly installed at the center of the connecting screen plate, and several through holes are evenly provided on the connecting screen plate, so that when the vertical stirring assembly moves up and down, the internal fluid material generates a flow rate difference under the action of the through holes, effectively improving the mixing effect.

[0014] As a preferred technical solution of this application, the inner sides of the upper and lower edges of the scraping ring frame are both chamfered, and the scraping ring frame is in contact with the inner wall of the mixing hopper. Thus, as the two sets of vertical stirring components move up and down with the action of the push rod motor, the inner wall of the side of the mixing hopper is effectively scraped, avoiding the occurrence of sticking.

[0015] As a preferred technical solution of this application, the connecting screen plate is evenly provided with a number of waist-shaped through holes pointing to the center, and a stirring roller is rotatably provided at the strip-shaped through holes. The stirring roller is evenly provided with grooves. The grooves can carry part of the material along the axial direction when moving up and down. At the same time, the shearing action of the groove edge can tear the material agglomerates and improve the uniformity of mixing.

[0016] As a preferred technical solution of this application, the bottom scraping assembly includes a rotating sleeve rotatably sleeved on the outer side of the bottom of the air guide shaft tube. Several sets of arc scrapers are uniformly fixedly connected to the outer side of the rotating sleeve. The edges of the arc scrapers are in contact with the inner wall of the mixing bucket, so that the material can be effectively scraped and pushed during rotation, avoiding sticking and facilitating discharge. A threaded sleeve sleeved on the outer side of the air guide shaft tube is fixedly connected to the top of the rotating sleeve. The outer side of the threaded sleeve is provided with external threads, and the inner side of the central sleeve on the lower vertical mixing assembly is provided with internal threads that are adapted to the threaded sleeve. Thus, when the vertical mixing assembly moves up and down, it can effectively drive the threaded sleeve, the rotating sleeve and the arc scrapers to rotate, thereby achieving effective scraping treatment of the bottom inner wall of the mixing bucket.

[0017] As a preferred technical solution of this application, the outer side of the threaded sleeve is provided with air outlet holes evenly distributed along the thread groove, and the lower outer side of the air guide tube is provided with air guide holes corresponding to the air outlet holes on the threaded sleeve. By injecting high-speed airflow, solid debris inside the concrete during the concrete processing is effectively prevented from remaining in the thread groove, thus avoiding blockage and ensuring smooth use for a long time. Furthermore, when the bottom scraping component rotates with the vertical mixing component, the air outlet holes and air guide holes can periodically overlap, thereby injecting air from the bottom of the mixing hopper. During the rising process of the air bubbles, they are broken up by the vertical mixing component, further improving the mixing effect.

[0018] As a preferred technical solution of this application, the top connecting assembly includes a connecting plate coaxially connected to the output shaft of the push rod motor, an air pump is installed at the bottom end of the connecting plate, and an air spring tube connected to the air outlet end of the air pump is connected to the top end of the air guide shaft tube, thereby effectively ensuring the stable progress of the air filling process.

[0019] Several sets of fixing rods are evenly fixedly connected to the lower side of the connecting plate. The fixing rods are fixedly connected to the top of the vertical stirring component located above, thereby effectively ensuring the stable up-and-down adjustment of the two sets of vertical stirring components.

[0020] As a preferred technical solution of this application, the bottom end of the mixing bucket is provided with a discharge port, and a discharge block plate is rotatably provided at the discharge port, and three sets of support seats are fixedly installed on the lower outer side of the mixing bucket.

[0021] The beneficial effects of this invention are as follows:

[0022] 1. Significantly improves mixing uniformity: Through the vertical movement of the mixing component and the coordination of the stirring roller, combined with the micro-vortex formed by the circular hole, the material is axially tumbled and radially sheared; the full-height disturbance generated by the breaking of the injected air bubbles effectively breaks up agglomerates, improves the aggregate coating rate, effectively controls the concrete strength deviation, and solves the problem of "macroscopic uniformity but microscopic inhomogeneity" in traditional mixing. In this process, the air outlet on the threaded groove of the threaded sleeve, in conjunction with the air outlet of the air guide tube, ensures that the threaded groove of the threaded sleeve is effectively cleaned during use, avoiding blockage and the phenomenon that affects the screw drive.

[0023] 2. Efficiently solves the problem of sticking to the walls and dead corners: The chamfered edge scraping of the scraper ring and the bottom scraping component work together to effectively reduce the amount of material residue on the walls and bottom; the scraper's gathering effect prevents the accumulation of aggregate at the bottom, and the air bubble effect eliminates the stagnant layer in the internal material, achieving full-space mixing without dead corners in the mixing hopper;

[0024] 3. Reduced energy consumption and improved efficiency: The vertical stirring component is driven by a single power source to open and close the linkage rod and the air circulation process, which effectively reduces energy consumption during use; the bubble breaking optimizes the material flowability, reduces the moving resistance of the vertical stirring component, shortens the stirring cycle, and improves production efficiency.

[0025] In summary, this application can effectively ensure the uniformity of concrete processing in actual use, avoid the problems of sticking to the inner wall and dead corners not being cleaned, and can also effectively reduce energy consumption and improve mixing efficiency.

[0032] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0033] Reference Figures 1-5 A concrete processing apparatus for construction engineering, comprising:

[0034] Mixing hopper 1 is used for carrying and mixing concrete materials;

[0035] A top support plate 3 is set above the mixing hopper 1. Several sets of connecting bent rods 2 are evenly arranged on the upper outer side of the mixing hopper 1. The connecting bent rods 2 are fixedly connected to the top support plate 3. A push rod motor 4 is installed at the top center of the top support plate 3.

[0036] The stirring assembly 5, located inside the stirring hopper 1, includes an air guide tube 51. The air guide tube 51 is coaxially fixed at the axis of the stirring hopper 1, providing stable support for the stirring operation and conducting airflow during the stirring process to improve the uniformity of mixing. A bottom scraper assembly 54 is rotatably sleeved on the lower outer side of the air guide tube 51, used to cover and scrape the inner wall of the bottom of the stirring hopper 1 to prevent material sticking. Two sets of vertical stirring assemblies 52 are sleeved on the upper outer side of the air guide tube 51. The vertical stirring assemblies 52 are used to effectively mix materials. The lower vertical stirring assembly 52 and the bottom scraper assembly 54 are connected to the bottom scraper assembly 54. The wiping component 54 is screw-driven, and a connecting rod 53 connects the two sets of vertical stirring components 52. The top of the vertical stirring component 52 is connected to a top connecting component 55, which is coaxially connected to the output shaft of the push rod motor 4. Thus, through the operation of the push rod motor 4, the vertical stirring component 52 can be effectively moved up and down, which facilitates the effective mixing of materials by means of the vertical stirring component 52. The up and down moving vertical stirring component 52 causes the bottom scraping component 54 below to work in a screw-driven manner to effectively scrape the inner wall of the mixing bucket 1, thus avoiding the phenomenon of material sticking.

[0037] The bottom of the mixing bucket 1 is provided with a discharge port, and a discharge block plate is rotatably installed at the discharge port. Three sets of support seats 6 are fixedly installed on the lower outer side of the mixing bucket 1.

[0038] Reference Figure 3 The vertical mixing assembly 52 includes a scraper ring frame 521, a connecting sieve plate 522 is installed on the inner side of the scraper ring frame 521, a central bushing 524 is fixedly installed at the center of the connecting sieve plate 522, and several through holes are evenly provided on the connecting sieve plate 522 to facilitate the vertical mixing assembly 52 to move up and down, so that the internal fluid material generates a flow rate difference under the action of the through holes, effectively improving the mixing effect.

[0039] The inner sides of the upper and lower edges of the scraping ring frame 521 are both chamfered, and the scraping ring frame 521 is in contact with the inner wall of the mixing hopper 1. As the two sets of vertical stirring components 52 move up and down with the push rod motor 4, they effectively scrape the inner wall of the side of the mixing hopper 1, thus avoiding sticking.

[0040] The connecting screen plate 522 is evenly provided with several sets of waist-shaped through holes pointing to the center, and a stirring roller 523 is rotatably provided at the strip-shaped through holes. The stirring roller 523 is evenly provided with grooves. The grooves can carry part of the material along the axial direction when moving up and down. At the same time, the shearing action of the groove edge can tear the material agglomerates and improve the uniformity of mixing.

[0041] Reference Figure 4 The bottom scraping assembly 54 includes a rotating sleeve 542 rotatably sleeved on the outer side of the bottom of the air guide tube 51. Several sets of arc scrapers 543 are evenly fixedly connected to the outer side of the rotating sleeve 542. The edges of the arc scrapers 543 are in contact with the inner wall of the mixing bucket 1, so that the material can be effectively scraped and pushed during rotation, avoiding sticking and facilitating discharge. The top of the rotating sleeve 542 is fixedly connected to a threaded sleeve 541 sleeved on the outer side of the air guide tube 51. The outer side of the threaded sleeve 541 is provided with external threads, and the inner side of the central sleeve 524 on the lower vertical mixing assembly 52 is provided with internal threads that are compatible with the threaded sleeve 541. So that when the vertical mixing assembly 52 moves up and down, it can effectively drive the threaded sleeve 541, the rotating sleeve 542 and the arc scrapers 543 to rotate, thereby achieving effective scraping treatment of the bottom inner wall of the mixing bucket 1.

[0042] The outer side of the threaded sleeve 541 is evenly provided with air outlets along the threaded groove, and the lower outer side of the air guide tube 51 is provided with air guide holes corresponding to the air outlets on the threaded sleeve 541. By injecting high-speed airflow, solid debris inside the concrete during the concrete processing is effectively prevented from remaining in the threaded groove, thus avoiding blockage and ensuring smooth use for a long time. Furthermore, when the bottom scraper component 54 rotates with the vertical mixing component 52, the air outlets and air guide holes can periodically overlap, thereby injecting air from the bottom of the mixing hopper 1. During the rise of the air bubbles, they are broken up by the vertical mixing component 52, further improving the mixing effect.

[0043] Reference Figure 2 and Figure 5 The top connecting assembly 55 includes a connecting plate 554 coaxially connected to the output shaft of the push rod motor 4. An air pump 553 is installed at the bottom end of the connecting plate 554. The air outlet of the air pump 553 is connected to an air guide spring tube 552 that communicates with the top end of the air guide shaft tube 51, thereby effectively ensuring the stable operation of the air filling process.

[0044] Several sets of fixing rods 551 are evenly fixedly connected to the lower side of the connecting plate 554. The fixing rods 551 are fixedly connected to the top of the vertical stirring component 52 located above, thereby effectively ensuring the stable up and down adjustment of the two sets of vertical stirring components 52.

[0045] Workflow: In actual use, the push rod motor 4 first lifts the two sets of vertical mixing components 52 until the lower vertical mixing component 52 is above the mixing hopper 1. Then, the cement for concrete processing is guided into the interior of the mixing hopper 1. Then, the push rod motor 4 is started again to move the vertical mixing component 52 into the interior. After the vertical mixing component 52 moves into the interior, the central bushing 524 on the lower vertical mixing component 52 engages with the threaded sleeve 541. Under the action of the up and down movement, the two are engaged in spiral transmission, which drives the bottom scraping component 54 to rotate as a whole. The arc scraper 543 follows the rotation to effectively scrape the inner wall of the bottom of the mixing hopper 1, avoiding the occurrence of sedimentation and sticking.

[0046] During the rotation of the threaded sleeve 541, the air outlet on the threaded sleeve 541 and the air guide hole on the air guide shaft tube 51 periodically coincide. Under the continuous air injection action of the air pump 553 above, the blockage of the air outlet and the air guide hole is effectively avoided, so that the airflow periodically injects into the mixed material, forming bubbles at the bottom. During the upward movement, the bubbles are broken by the vertical stirring component 52. The small bubbles broken by the stirring ring have a longer residence time in the material and can diffuse to the upper part of the mixing bucket 1, forming "full-height airflow disturbance", promoting the convection of the upper and lower materials. Moreover, its surface tension can "pull" the surrounding materials to form micro vortices, which can tear apart micro-agglomerates such as cement lumps and aggregate clumps, allowing the cement paste to more evenly coat the aggregate, reducing the problem of concrete strength deviation, and also reducing material adhesion and agglomeration, optimizing material flowability.

[0047] When the vertical stirring component 52 moves, the groove can carry part of the material along the axial direction when it moves up and down due to the setting of the stirring roller 523. At the same time, the shearing action of the groove edge can tear apart the material agglomerates and improve the uniformity of mixing.

[0048] When the connecting screen plate 522 moves, the through holes on the connecting screen plate 522 cause the viscous material to exhibit two flow states. Part of the material moves up and down with the connecting screen plate 522, while the other part of the material moves at a lower speed relative to the connecting screen plate 522 due to frictional resistance. This creates a speed difference with the surrounding material moving at the same speed, ultimately forming a micro-vortex inside. This effectively and directly acts on the agglomerates in the concrete material, realizing the tearing-reconstruction process, thereby effectively ensuring the uniformity of the mixture and ultimately ensuring the uniformity of the concrete strength.
