Description

Technical Field

[0001] This utility model relates to the field of concrete production equipment technology, specifically to a concrete admixture quantitative batching device. Background Technology

[0002] In modern construction engineering, concrete is widely used as a basic material. To enhance the performance of concrete, such as improving its fluidity, strength, and durability, it is often necessary to add a certain amount of admixtures during the concrete processing. These admixtures include various types such as water-reducing agents, air-entraining agents, and waterproofing agents, each with its specific function and applicable scope.

[0003] Traditional quantitative batching devices can batch admixtures according to fixed ratios, but they cannot flexibly adjust the amount of each admixture added. In practical applications, considering the different needs of different engineering projects, if the amount of a certain admixture is not adjusted, the optimal performance of various admixtures cannot be achieved, which limits the potential for improving concrete performance and further reduces the practicality of the device. Therefore, we propose a concrete admixture quantitative batching device to solve the above problems. Utility Model Content

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0025] This application provides a concrete admixture quantitative batching device, mainly to address the problem in existing technologies where different engineering projects have different requirements. Without adjusting the dosage of a certain admixture, the optimal performance of various admixtures cannot be achieved, limiting the potential for improving concrete performance and further reducing the practicality of the device. The following technical solution is provided, which will be discussed in conjunction with... Figures 1-5 Please provide a detailed explanation:

[0026] A concrete admixture quantitative batching device includes: a mounting box 1, the upper and lower ends of the mounting box 1 are open structures, guide rods 2 are fixed on both sides of the top of the mounting box 1, and a fixing plate 3 is fixed on the top of the guide rods 2.

[0027] Storage cylinders 4 are embedded at equal intervals on the surface of fixed plate 3, and the bottom of storage cylinders 4 is connected to guide pipes 401;

[0028] The metering dispensing mechanism 5 is used to add additives in a metering manner. The metering dispensing mechanism 5 includes a metering cylinder 501 embedded inside the mounting box 1. The bottom of the metering cylinder 501 is an open structure. The end of the guide tube 401 away from the storage cylinder 4 is connected to the middle of the metering cylinder 501. A hydraulic cylinder 508 is installed in the middle of the top of the fixing plate 3. The piston end of the hydraulic cylinder 508 is connected to a lifting plate 502. The lifting plate 502 is slidably sleeved on the surface of the guide rod 2. A sliding rod 503 is fixed at the bottom of the lifting plate 502. The sliding rod 503 slides through the top wall of the metering cylinder 501 and is connected to a first sliding plug 504. The bottom of the first sliding plug 504 is connected to an extension rod 505. A second sliding plug 506 is slidably sleeved on the surface of the extension rod 505. Both the first sliding plug 504 and the second sliding plug 506 are slidably connected to the cylinder wall of the metering cylinder 501.

[0029] Locking element 6 is provided on the bottom side of extension rod 505, and locking element 6 is used to fix the second slide plug 506.

[0030] Workflow Description:

[0031] Step 1, Preparation Phase

[0032] Various admixtures are loaded into storage cylinders 4 respectively, ensuring that the type and amount of admixtures in each storage cylinder 4 meet the project requirements. Key components such as hydraulic cylinder 508 and vibration motor 507 are checked for proper functioning to ensure the equipment is in good condition. Based on the project's requirement for a specific admixture, the position of the second slide plug 506 on the extension rod 505 is changed via locking element 6. This alters the distance between the first slide plug 504 and the second slide plug 506, thereby adjusting the dosage of the admixture falling into the metering cylinder 501 (at the hydraulic cylinder 508). When the piston end is in the contracted state, the first slide plug 504 abuts against the inner top wall of the metering cylinder 501. At this time, the deeper the second slide plug 506 extends into the metering cylinder 501, the smaller the distance between the first slide plug 504 and the second slide plug 506, and the less the added dose falls into the metering cylinder 501. Conversely, the shallower the second slide plug 506 extends into the metering cylinder 501, the greater the distance between the first slide plug 504 and the second slide plug 506, and the more the added dose falls into the metering cylinder 501, thus realizing the quantitative dispensing of the additive.

[0033] The second step is the material discharge stage.

[0034] The piston end of the hydraulic cylinder 508 extends, causing the lifting plate 502 to slide downward along the guide rod 2, which in turn drives the first sliding plug 504 and the second sliding plug 506 to move downward. When the second sliding plug 506 moves to the outside of the metering cylinder 501, the admixture can fall downward into the designated container (concrete mixing device). During this process, the first sliding plug 504 slides inside the metering cylinder 501, which can seal the lower port of the feed pipe 401 and prevent the admixture from entering the interior of the metering cylinder 501.

[0035] The third step, the reset phase.

[0036] The hydraulic return piston retracts, causing the lifting plate 502 to slide upward along the guide rod 2, which in turn drives the first slide plug 504 and the second slide plug 506 to move upward. When the first slide plug 504 comes into contact with the inner top wall of the metering cylinder 501 again, the upper end of the first slide plug 504 also enters the interior of the metering cylinder 501, preventing the additive from falling and completing one batching process.

[0037] The concrete admixture quantitative batching device adjusts the position of the second slide 506 by setting a locking element 6, which can change the distance between the first slide 504 and the second slide 506, thereby adjusting the amount of admixture falling into the quantitative cylinder 501. This makes the device not only able to complete the quantitative addition of admixture, but also able to change the quantitative value as needed, making it highly practical.

[0038] like Figure 5As shown, in some embodiments, the first slide 504 has a hollow structure, and a vibration motor 507 is installed on its inner bottom side. More specifically, without the vibration motor 507, powdered additives may adhere to the inner wall of the feed tube 401 or the metering cylinder 501 due to static electricity, humidity or other reasons, resulting in blockage. When the vibration motor 507 is started, it generates vibration force. Due to the physical characteristics of vibration, the powdered material is more likely to flow and rearrange when it is vibrated, thereby reducing the mutual adsorption and friction between powders, so that the powder can fall into the metering cylinder 501 more smoothly. When the second slide 506 is located outside the metering cylinder 501, some additive powder that has not completely fallen into the metering cylinder 501 may be attached to its top. If these powders are not cleaned up in time, they will not only affect the accuracy of the next batch of ingredients, but the introduction of the vibration motor 507 can make it easier to shake off the powders attached to the top of the second slide plug 506 through its vibration action. Through the action of the vibration motor 507, it can be ensured that the additive powders can fall accurately into the designated container each time ingredients are dispensed.

[0039] like Figure 5 As shown, in some embodiments, the top surface of the second slide 506 is spherical. More specifically, the spherical top surface makes it difficult for the admixture to stay or accumulate on the top of the second slide 506. A flat top surface is prone to forming dead corners, causing the admixture to accumulate in these areas. The spherical design effectively avoids this problem, ensuring the smooth flow of the admixture. The shape of the top surface helps the admixture to slide down quickly under the action of gravity.

[0040] like Figure 3 As shown, in some embodiments, the locking member 6 includes a connecting tube 601 fixed in the middle of the bottom of the second slide plug 506. The connecting tube 601 has a thread on the side near the second slide plug 506, and a strip-shaped notch 6011 is arranged in an annular array at its lower end. A locking sleeve 602 is slidably sleeved on the bottom side of the extension rod 505. The locking sleeve 602 can be threadedly connected to the connecting tube 601, and its bottom end is tapered. More specifically, when it is necessary to fix the second slide plug 506, the locking sleeve 602 can be rotated so that the connecting tube 601 and the locking sleeve 602 are screwed together. Since the bottom end of the locking sleeve 602 is tapered, when the lower end of the connecting tube 601 enters the narrow space inside the locking sleeve 602, it will converge towards the middle and clamp the extension rod 505, thus preventing the second slide plug 506 from moving on the extension rod 505.

[0041] like Figure 2As shown, in some embodiments, the metering cylinder 501 is a transparent plastic cylinder, and a transparent observation window 101 is provided on the front of the mounting box 1 corresponding to the metering cylinder 501. More specifically, since the metering cylinder 501 is transparent, the operator can intuitively observe the flow and accumulation of the additive inside and outside the cylinder, thereby better understanding the dispensing process. The transparent observation window 101 on the front of the mounting box 1 corresponding to the metering cylinder 501 allows the operator to directly observe the situation inside the metering cylinder 501 without opening the mounting box 1.

[0042] like Figure 2 As shown, in some embodiments, mounting plates 7 are fixed to the bottom of both sides of the mounting box 1. The mounting plates 7 are L-shaped and have mounting holes on their bottom surfaces. More specifically, when this device is used, it is generally installed above the stirring vessel. The mounting plates 7 can be fixed to the upper edge of the reaction vessel by bolts.

[0043] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
