Description

Technical Field

[0001] This utility model relates to the field of concrete processing technology, and in particular to a quantitative addition device for concrete additives. Background Technology

[0002] In the concrete production process, various additives are often added in precise quantities to improve concrete performance. Currently, metering valves are commonly used to achieve this precise addition. However, existing additive storage tanks are prone to additive agglomeration due to the inherent properties of the additives or changes in temperature and humidity during storage. These agglomerated lumps can clog the metering valve or block the metering channel, interfering with the valve's precise control over the additive flow, leading to inaccurate metering and affecting the concrete mix proportions and final performance. Furthermore, frequent cleaning or maintenance of the metering valve can reduce production efficiency and increase production costs. Utility Model Content

[0003] In view of this, the present invention proposes a quantitative addition device for concrete additives, which can utilize the power of stirring to pre-disperse the additives and ensure the accuracy of quantitative addition.

[0004] The technical solution of this utility model is implemented as follows: A quantitative addition device for concrete additives includes a processing tank, a stirring rod, a storage tank, an addition pipe, a metering valve, and a dispersing mechanism.

In a processing tank, concrete raw materials are mixed and processed using a stirring rod. During processing, a metering valve is opened to quantitatively add the additive to the storage tank. Before adding the concrete additive, a lifting plate is lowered, engaging the transmission bevel gear with the driving bevel gear. This allows the rotational force of the stirring rod to be transmitted to the transmission shaft.

As the lifting plate descends, the shaft drives a dispersing rod into the storage tank. When the shaft rotates, the dispersing rod disperses the concrete additive in the storage tank, preventing clumping and ensuring accurate quantitative addition. It also prevents blockage of the addition tube. Attached Figure Description

[0016] To better understand the technical content of this utility model, a specific embodiment is provided below, and the utility model will be further described in conjunction with the accompanying drawings.

[0017] See Figures 1 to 3 This utility model provides a quantitative addition device for concrete additives, comprising a processing tank 1, a stirring rod 2, a storage tank 3, an addition pipe 4, a metering valve 5, and a dispersing mechanism. The stirring rod 2 is located in the processing tank 1, with its top end extending above the outside of the processing tank 1. The storage tank 3 is located on the top surface of the processing tank 1, with its top surface open. The top end of the addition pipe 4 is connected to the bottom surface of the storage tank 3, and its bottom end extends into the processing tank 1. The metering valve 5 is located on the addition pipe 4. The dispersing mechanism includes a driving bevel gear 6, a lifting plate 7, a mounting plate 8, a transmission shaft 9, a transmission bevel gear 10, a rotating shaft 11, a dispersing rod 12, and a driven bevel gear 13. The active bevel gear 6 is located at the top of the stirring rod 2, the lifting plate 7 is located above the processing tank 1, the mounting plate 8 is located on the bottom surface of the lifting plate 7, the transmission shaft 9 passes through the mounting plate 8 and is rotatably connected to the mounting plate 8, the transmission bevel gear 10 is located at both ends of the transmission shaft 9, the top of the rotating shaft 11 is rotatably connected to the bottom surface of the lifting plate 7, the storage tank 3 is located below the rotating shaft 11, the dispersing rod 12 is located on the outer wall of the rotating shaft 11, the driven bevel gear 13 is located on the rotating shaft 11 and meshes with the transmission bevel gear 10 at one end of the transmission shaft 9, and the active bevel gear 6 is located on the moving path of the transmission bevel gear 10 at the other end of the transmission shaft 9.

[0018] During concrete production, materials such as water, aggregates, and cement can be added to the processing tank 1. The raw materials can be mixed by the stirring rod 2 inside the processing tank 1 to produce concrete. During the production process, concrete additives stored in the storage tank 3 can be added to the processing tank 1 through the addition pipe 4. When the metering valve 5 is opened, the concrete additives can be added quantitatively to ensure the accuracy of the mix ratio.

[0019] The concrete additive in storage tank 3 may clump during long-term storage. Therefore, it can be broken up by a dispersing mechanism before adding the concrete additive. An active bevel gear 6 is installed at the top of the mixing tank. During dispersing, the lifting plate 7 is raised or lowered, lowering the transmission bevel gear 10 to the position of the active bevel gear 6 and engaging it. This allows the rotational force of the mixing rod 2 to be transmitted to the transmission shaft 9 via the transmission bevel gear 10, causing the transmission shaft 9 to rotate. A similar transmission bevel gear 10 is also installed on the other side of the transmission shaft 9. The 0 can drive the driven bevel gear 13 meshing with it to rotate, thereby transmitting the rotational force to the rotating shaft 11, and driving the dispersing rod 12 on the rotating shaft 11 to rotate synchronously. During the descent of the lifting plate 7, the rotating shaft 11 and the dispersing rod 12 can enter the storage tank 3. When the rotating shaft 11 rotates, the dispersing rod 12 can disperse the concrete additive in the storage tank 3, making the concrete additive uniform in size, so that the metering valve 5 can accurately detect the amount of concrete additive added. At the same time, dispersing can avoid clogging of the addition pipe 4, ensuring the stable addition of concrete additive.

[0020] Preferably, it also includes a stirring mechanism, which includes blades 14 and a drive motor 15. The blades 14 are disposed on the outer wall of the stirring rod 2 and located inside the processing tank 1. The drive motor 15 is disposed on the bottom surface of the processing tank 1, and its output shaft extends into the processing tank 1 and is connected to the bottom end of the stirring rod 2.

[0021] The drive motor 15 provides power to the stirring rod 2. The stirring rod 2 can drive the blade 14 to rotate, thereby stirring the raw materials in the processing tank 1. On the other hand, it can drive the active bevel gear 6 to rotate. When the transmission bevel gear 10 meshes with the active bevel gear 6, it can transmit the rotational force to the rotating shaft 11, thereby dispersing the concrete additive.

[0022] Preferably, the dispersing mechanism further includes an electric push rod 16, which is disposed on the top surface of the processing tank 1, and its output shaft is connected to the bottom surface of the mounting plate 8.

[0023] The electric push rod 16 can drive the lifting plate 7 to rise and fall through the mounting plate 8, thereby lowering the transmission bevel gear 10 to mesh with the driving bevel gear 6, and at the same time lowering the rotating shaft 11 and the dispersing rod 12 into the storage tank 3.

[0024] Preferably, the dispersing mechanism further includes a bearing 17, which is disposed on the bottom surface of the lifting plate 7 and embedded in the mounting plate 8. The top end of the rotating shaft 11 is connected to the bearing 17 on the bottom surface of the lifting plate 7, and the middle part of the transmission shaft 9 is connected to the bearing 17 on the mounting plate 8.

[0025] When the transmission shaft 9 and the rotating shaft 11 are rotating, they can rotate stably with the support of the bearing 17.

[0026] Preferably, it also includes a support foot 18, which is disposed on the bottom surface of the processing tank 1.

[0027] The support feet 18 provided can provide stable support for the processing tank 1, ensuring that the drive motor 15 drives the stirring rod 2 to rotate.

[0028] Preferably, the dispersing mechanism further includes a guide rod 19, the bottom end of which is connected to the top surface of the processing tank 1, and the top end of which passes through the lifting plate 7.

[0029] To ensure that the lifting plate 7 does not deviate when it moves, a guide rod 19 is provided on the processing tank 1. This ensures that the lifting plate 7 does not deviate when it rises and falls, and that the transmission bevel gear 10 can accurately mesh with the driving bevel gear 6.

[0030] Preferably, it also includes a feed pipe 20, a discharge pipe 21, and a valve 22. The feed pipe 20 and the discharge pipe 21 are disposed on the outer wall of the processing tank 1, and the valve 22 is disposed on the feed pipe 20 and the discharge pipe 21.

[0031] Raw materials can be added to the processing tank 1 through the feed pipe 20. After processing, the material in the processing tank 1 can be discharged to the outside through the discharge pipe 21. The feed pipe 20 and the discharge pipe 21 can be opened and closed by the control of the valve 22.

[0032] Preferably, the bottom surface of the processing tank 1 is configured as an inclined structure, with the lower part of the tank located on one side of the discharge pipe 21.

[0033] In order to ensure that all the material inside the processing tank 1 is discharged, the bottom surface of the processing tank 1 is set as an inclined structure. Under the action of gravity, the processed material can be discharged from the discharge pipe 21.

[0034] Preferably, it also includes an elastic rubber diaphragm 23, which is symmetrically arranged on the top surface of the storage tank 3 and is arranged in multiple layers, with the rotating shaft 11 and the dispersing rod 12 located above the elastic rubber diaphragm 23.

[0035] The multi-layered rubber elastic diaphragm can seal the storage tank 3. When the rotating shaft 11 descends with the lifting plate 7, it can push the multi-layered rubber elastic diaphragm downward to open it, so that the rotating shaft 11 and the dispersing rod 12 can enter the storage tank 3.
