Description

Technical Field

[0001] This invention relates to the technical field of building material preparation machinery, and more particularly to a production apparatus for a concrete expansion agent. Background Technology

[0002] The production equipment for concrete expansion agents refers to specialized mechanical equipment and systems used to manufacture concrete expansion agents (an admixture that enables concrete to produce controlled volume expansion during the hardening process). Its core function is to transform raw materials (such as sulfoaluminates, calcium oxides, magnesium oxides, etc.) into standard-compliant and stable powdered or liquid products through processes such as crushing, grinding, homogenization, and mixing.

[0003] In related technologies, existing concrete expansion agent production equipment mostly adopts a segmented, independent equipment structure, typically including jaw crushers, ball mills, mixers, and conveyor units arranged in series, with each process connected by mechanical conveying devices. In practical applications, this structure results in a fragmented process flow, requiring multiple material transfers and lifts, leading to large equipment footprint, high energy consumption, and dust pollution. Independent operation of each process makes it difficult to coordinate the control of grinding particle size and mixing uniformity, easily causing material stratification or agglomeration. Furthermore, traditional valve-based discharge mechanisms have poor adaptability to powdery materials, easily causing arching and blockage when the material moisture content is high. In addition, the complex multi-equipment drive system, numerous maintenance points, and low automation integration further restrict production efficiency and controllability. These problems directly affect production continuity and product stability, especially for special expansion agents requiring fine processing, making efficient and homogenized production difficult. Summary of the Invention

[0004] The present invention aims to at least partially solve one of the technical problems in the related art.

[0005] Therefore, the purpose of this invention is to propose a production device for concrete expansion agent, which adopts an integrated closed cylinder structure and integrates crushing, grinding and mixing processes, realizing continuous and coordinated material processing and smooth and controllable discharge. It solves the problems of difficult coordinated control, easy material blockage and dust pollution in traditional segmented equipment, and significantly improves production efficiency and product homogeneity.

[0006] To achieve the above objectives, the present invention proposes a production apparatus for a concrete expansion agent, comprising a processing cylinder, a pretreatment mechanism, and a crusher. The processing cylinder has a discharge port on its outer circumference at one end. The crusher is located at the end of the processing cylinder furthest from the discharge port and is connected to the processing cylinder. The pretreatment mechanism includes a sealing component, a first driving component, and a processing component. The sealing component is located on the processing cylinder and outside the discharge port. The processing component is rotatably connected to the processing cylinder via the first driving component.

[0007] In addition, the concrete expansion agent production apparatus according to the present invention may also have the following additional technical features: Specifically, the sealing assembly includes a connecting sleeve, a second driving member, and a sealing plate. The connecting sleeve is rotatably connected to the processing cylinder and located outside the discharge port. The sealing plate is movably connected to the inside of the processing cylinder through the second driving member and is used to seal the discharge port.

[0008] Specifically, the first driving assembly includes a first driving member, a connecting shaft, and a support plate. The support plate is disposed inside the processing cylinder and near the discharge port. The connecting shaft is rotatably connected to the inside of the processing cylinder via the first driving member, is coaxially disposed with the processing cylinder, and is rotatably connected to the support plate.

[0009] Specifically, the processing assembly includes a propulsion component, a grinding component, and a stirring component, wherein the propulsion component, the grinding component, and the stirring component are sequentially arranged on the connecting shaft and rotate synchronously with the connecting shaft.

[0010] Specifically, the propulsion component is located below the crusher, the agitator is close to the discharge port, and the grinding component is frustum-shaped and located between the agitator and the propulsion component.

[0011] Compared with the prior art, the technical solution provided by the present invention has the following beneficial effects: The concrete expansion agent production device of the present invention integrates crushing, grinding and mixing processes into a single closed processing cylinder, realizing continuous and integrated operation of materials during the flow process. This not only significantly reduces the equipment footprint and material transfer energy consumption, but also controls dust pollution at the source. By using coaxial linkage propulsion, grinding and stirring, the progressive grinding and instant homogenization of materials are completed simultaneously in a dynamic closed space, effectively solving the problem of difficulty in coordinating the control of grinding particle size and mixing uniformity in traditional segmented equipment, and avoiding material stratification and agglomeration. At the same time, it ensures the smooth and controllable discharge of powdered materials under fluctuating moisture content conditions, eliminates the risk of arching and blockage, and comprehensively improves the production efficiency, product homogeneity and reliability of the concrete expansion agent pre-processing stage.

[0012] Additional aspects and advantages of the invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0015] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the invention, and should not be construed as limiting the invention. Rather, embodiments of the invention include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.

[0016] The production apparatus for concrete expansion agent according to an embodiment of the present invention will now be described with reference to the accompanying drawings.

[0017] like Figures 1-3 As shown, the concrete expansion agent production device of this embodiment may include a processing cylinder 1, a pretreatment mechanism 2, and a crusher 3.

[0018] The processing cylinder 1 has a discharge port 11 on the outer circumference of one end, and the crusher 3 is located at the end of the processing cylinder 1 away from the discharge port 11 and is connected to the processing cylinder 1.

[0019] It should be noted that, in this embodiment, the processing cylinder 1 is horizontally positioned, with a crusher 3 replacing the original feed inlet. The discharge outlet 11 is located at the far end of the processing cylinder 1. After further pre-processing by the pre-treatment mechanism 2, the material is fed to the homogenizing equipment. The crusher 3 employs a gear-meshing, opposing rolling structure.

[0020] The pretreatment mechanism 2 includes a sealing component 21, a first drive component 22, and a processing component 23.

[0021] The sealing and feeding assembly 21 is disposed on the processing cylinder 1 and located outside the discharge port 11. The processing assembly 23 is rotatably connected to the processing cylinder 1 through the first driving assembly 22.

[0022] It should be noted that the first driving component 22 proposed in the above embodiment drives the processing component 23 to rotate synchronously inside the processing cylinder 1, pushing, grinding and mixing the crushed raw materials. At the same time, the sealing component 21 is used to seal the cross section of the processing cylinder 1 near the discharge port 11, sealing one end of the processing cylinder 1 to achieve closed processing.

[0023] Specifically, in practical applications, operators feed raw materials into the feed inlet of crusher 3, which employs a counter-rotating crushing roller structure, serving as both a primary crusher and the feed channel for processing cylinder 1. This device is used for the pre-grinding and pre-mixing of concrete expansion agent raw materials. By performing preliminary crushing, grinding, and homogenization of the materials, it provides intermediate products that meet the feed requirements for subsequent fine homogenization processes.

[0024] In the initial state, the sealing plate 213 is tightly fitted with the support plate 223 under the pushing action of the second driving member 212, so as to achieve a reliable seal on the cross section of the discharge port 11 of the processing cylinder 1 and prevent the material from leaking accidentally during the processing.

[0025] During feeding, the raw material, after being coarsely crushed by crusher 3, falls into the feed end of processing cylinder 1. Driven by the first drive component 221, the connecting shaft 222 drives the propeller 231, grinding component 232, and agitator 233 to rotate synchronously. The propeller 231 adopts a spiral blade structure to convey the material towards the grinding component 232; the grinding component 232 is a frustum-shaped grinding roller, and the material is subjected to progressive compression and shearing as it moves from the small diameter end to the large diameter end, achieving particle size refinement; the ground material then enters the action area of ​​the agitator 233, where it is initially mixed under the tumbling and scattering action of the agitator 233. Since the discharge port 11 is in a closed state, the material is continuously stirred at the end of the cylinder to achieve preliminary homogenization.

[0026] Once the material reaches the preset grinding fineness and mixing uniformity, the connecting sleeve 211 is first flipped to the position with the opening facing downwards. Then, the second driving component 212 is driven to retract the sealing plate 213, so that the discharge port 11 of the processing cylinder 1 is fully opened. The pre-processed material falls out of the discharge port 11 under the assistance of gravity and stirring, and is discharged in a concentrated manner by the guiding action of the connecting sleeve 211, entering the downstream homogenizing equipment for further processing.

[0027] In one embodiment of the present invention, such as Figure 2 and Figure 3 As shown, the sealing assembly 21 includes a connecting sleeve 211, a second driving component 212, and a sealing plate 213.

[0028] The connecting sleeve 211 is rotatably connected to the processing cylinder 1 and located outside the discharge port 11. The sealing plate 213 is movably connected to the inside of the processing cylinder 1 through the second driving member 212 and is used to seal the discharge port 11.

[0029] It should be noted that the second driving component 212 described in this embodiment is a cylinder, which drives the sealing plate 213 to move axially along the processing cylinder 1. The sealing plate 213 has a circular structure, and its outer circumference slides against the inner wall of the processing cylinder 1, effectively sealing the cross-section of the processing cylinder 1. The connecting sleeve 211 has a cavity structure with an opening on one side. In the initial state, it is wrapped around the outside of the discharge port 11. The discharge of the pre-made raw material is controlled by rotation, forming a dual control of material feeding with the sealing plate 213.

[0030] In one embodiment of the present invention, such as Figure 2 and Figure 3 As shown, the first drive assembly 22 includes a first drive member 221, a connecting shaft 222, and a support plate 223.

[0031] The support plate 223 is disposed inside the processing cylinder 1 and near the discharge port 11. The connecting shaft 222 is rotatably connected to the inside of the processing cylinder 1 via the first driving member 221, and is coaxially arranged with the processing cylinder 1 and rotatably connected to the support plate 223. It should be noted that the first driving component 221 proposed in the above embodiment is a rotary motor, and the support plate 223 supports the connecting shaft 222 at one end of the processing cylinder 1 near the discharge port 11, so that the connecting shaft 222 can rotate under the driving action of the first driving component 221.

[0032] In one embodiment of the present invention, such as Figure 2 and Figure 3 As shown, the processing component 23 includes a propulsion component 231, a grinding component 232, and a stirring component 233.

[0033] The propulsion component 231, the grinding component 232, and the stirring component 233 are sequentially arranged on the connecting shaft 222 and rotate synchronously with the connecting shaft 222.

[0034] It should be noted that the propulsion component 231 described in this embodiment adopts a spiral blade and is located directly below the crusher 3. The grinding component 232 adopts a frustum-shaped structure, with the smaller diameter end close to the propulsion component 231. Finally, the stirring component 233 adopts a fishbone structure to stir and mix the ground raw materials.

[0035] In summary, the concrete expansion agent production device of this invention adopts an integrated closed cylinder structure and integrates crushing, grinding and mixing processes, realizing continuous and coordinated material processing and smooth and controllable discharge. It solves the problems of difficult coordinated control, easy material blockage and dust pollution in traditional segmented equipment, and significantly improves production efficiency and product homogeneity.
