Description

Technical Field

[0001] This utility model relates to the field of concrete early strength agent production technology, specifically to a mixing and stirring device for producing concrete early strength agents. Background Technology

[0002] Concrete accelerators are important admixtures that can significantly shorten the setting time of concrete and improve its early strength. They are widely used in rapid construction, low-temperature environment construction, and precast component production. The performance of accelerators is closely related to the uniformity of their raw material mixing. If the mixing is uneven, the accelerator may not disperse well in the concrete, affecting its setting-promoting effect and even causing inconsistent setting times in some areas, thus affecting the construction quality.

[0003] Currently, the following problems exist in the production process of early strength agents:

[0004] Uneven mixing: Traditional mixing equipment usually uses a unidirectional mixing method, which can easily lead to the accumulation of raw materials or insufficient mixing in some areas. In particular, the materials near the inner wall of the mixing drum are difficult to be effectively stirred, affecting the uniformity of mixing.

[0005] Insufficient fluidity: Some highly viscous raw materials (such as certain powdered early strength agent components) are prone to clumping or adhering to the inner wall of the mixing drum during the mixing process, reducing mixing efficiency.

[0006] Existing mixing equipment is prone to material sticking to its inner wall, making cleaning difficult.

[0007] Dust pollution: During the production of early strength agents, some powdered raw materials are prone to generating dust during mixing and discharge, which not only wastes raw materials but also pollutes the working environment and affects the health of operators.

[0008] In the existing technology, some improved mixing equipment adopts dual-shaft mixing or adds scraper structure, but there are still problems such as dead corners in mixing, low mixing efficiency, difficulty in cleaning, and poor dust control. Utility Model Content

[0009] The purpose of this utility model is to provide a uniform mixing equipment for producing concrete early strength agents, aiming to solve at least one of the technical problems existing in the prior art, such as mixing dead zones, low mixing efficiency, difficulty in cleaning, and poor dust control.

[0010] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0011] A mixing and stirring device for producing concrete early-strength agents includes a base plate, two opposing support plates mounted on the top of the base plate, a tank rotatably mounted between the two support plates, and a stirring component rotatably mounted inside the tank. A driving mechanism is fixedly mounted on one of the support plates, the driving mechanism being used to drive the tank and the stirring component to rotate simultaneously in opposite directions. A removable cover is fixedly mounted at the top of the tank's feed inlet, and a powder butterfly valve is fixedly mounted at the bottom of the tank's discharge inlet. The top of the base plate also includes a conveying mechanism and a docking mechanism. The docking mechanism is used to connect the conveying mechanism to the powder butterfly valve. The docking mechanism also includes a cleaning mechanism, the output end of which is in close contact with the bottom wall of the tank, for vibrating cleaning of the inner wall of the tank.

[0012] As a further embodiment of this utility model: an outer connecting sleeve is fixedly embedded at the same position on both of the two support plates, a connecting pipe is rotatably arranged inside the outer connecting sleeve, both connecting pipes are fixedly connected to the tank body, and a second bevel gear is fixedly arranged at the outer end of the connecting pipe near the driving mechanism, the second bevel gear being connected to the driving mechanism.

[0013] As a further embodiment of this utility model: the stirring component includes a stirring rod that passes through the tank and is rotatably connected between the two connecting pipes. The end of the stirring rod near the second bevel gear is fixedly connected to the first bevel gear. The first bevel gear is connected to the driving mechanism. The stirring rod is also provided with at least two sets of stirring blades, and the at least two sets of stirring blades are arranged on the stirring rod at different angles.

[0014] As a further embodiment of this utility model: the drive mechanism includes a servo motor fixedly mounted on the corresponding support plate, a reduction gearbox fixedly mounted on the output shaft end of the servo motor, and a transmission bevel gear fixedly mounted on the output shaft end of the reduction gearbox, wherein the first bevel gear and the second bevel gear are both meshed with the transmission bevel gear.

[0015] As a further embodiment of this utility model: a cover is installed on the support plate on which the drive mechanism is installed.

[0016] As a further embodiment of this utility model: the material conveying mechanism includes a material conveying pipe fixed to the top of the base plate, a spiral blade shaft rotatably installed inside the material conveying pipe, and a drive motor fixedly installed at one end of the material conveying pipe with its output shaft fixedly connected to the spiral blade shaft.

[0017] As a further embodiment of this utility model: the docking mechanism includes a docking pipe fixed to the bottom of the powder butterfly valve, a fixed pipe installed at the top of the feed inlet of the conveying pipe, a movable pipe slidably connected inside the fixed pipe, a docking seat fixed to the top of the movable pipe, at least two movable plates fixedly installed on the outer periphery of the docking seat, and a lifting assembly disposed on one side of the movable plate.

[0018] As a further embodiment of this utility model: the lifting assembly includes a mounting bracket fixed to the top of the base plate, a hydraulic push rod fixedly mounted on the mounting bracket and whose telescopic end is fixedly connected to the corresponding movable plate, and a guide rail fixed on the mounting bracket and slidably connected to the movable plate.

[0019] As a further embodiment of this utility model: the cleaning mechanism includes a fixed frame fixed to the top of the corresponding movable plate, support springs fixedly installed on both sides of the top of the fixed frame, a contact plate fixedly installed on the top of the support spring, and an electromagnetic vibrator fixedly installed on the bottom of the contact plate.

[0020] As a further embodiment of this utility model: the shape of the upper surface of the contact plate matches the shape of the outer surface of the bottom wall of the tank, and at least two contact plates are symmetrically distributed on the vertical center line of the tank.

[0021] The beneficial effects of this utility model are:

[0022] (1) This utility model drives the tank and the stirring component to rotate in opposite directions simultaneously through a driving mechanism. When the tank rotates, the powder is repeatedly aggregated and separated under the action of gravity and centrifugal force. At the same time, the stirring component rotating in opposite directions inside the tank directly stirs the powder, making the powder fully and evenly mixed. Compared with the stirring method in one direction, this utility model will not cause raw material accumulation or insufficient local mixing. In particular, the material near the inner wall of the tank can also be effectively stirred, which greatly improves the uniformity of powder mixing. It can also solve the problem that some highly viscous powders are prone to clumping or adhering to the inner wall of the tank during the stirring process, reducing the mixing efficiency.

[0023] (2) This utility model uses the extension and retraction of the hydraulic push rod to drive the docking seat and the docking pipe to dock and separate. At the same time, the moving pipe and the fixed pipe transport the powder to the conveying pipe, thereby realizing the powder receiving function of the device, realizing the closed conveying of the ultra-early strength agent, effectively avoiding the dust generated by the early strength agent during the discharge process due to scattering or flying, thereby improving the working environment and protecting the health of the operators.

[0024] (3) This utility model uses a hydraulic push rod to push the contact plate to contact the tank wall. The contact plate transmits the vibration of the electromagnetic vibrator, causing the powder adhering to the tank wall to separate and fall due to the vibration. This realizes the vibration cleaning function of the device, effectively preventing the material from adhering and accumulating on the tank wall, ensuring a smooth and unobstructed feeding process, and improving feeding efficiency.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or a specific orientational structure and operation. Therefore, they should not be construed as limitations on this utility model.

[0035] Furthermore, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0036] Please see Figure 1-6 As shown in the figure, this utility model embodiment provides a mixing and stirring device for producing concrete early strength agent, including a base plate 1. Two opposing support plates 2 are welded and fixedly installed on the top of the base plate 1. A tank 3 is rotatably mounted between the two support plates 2, and the tank 3 can rotate between the two support plates 2. A stirring component 4 is rotatably mounted inside the tank 3. A driving mechanism 5 is fixedly mounted on one of the support plates 2. Driven by the driving mechanism 5, the tank 3 and the stirring component 4 can rotate in opposite directions simultaneously, ensuring thorough mixing of the powder inside the tank 3. A removable cover 6 is fixedly mounted at the top feed port of the tank 3. The cover 6 can be securely sealed at the top feed port of the tank 3 by a threaded connection, ensuring that the powder does not leak from the top feed port of the tank 3 when it is rotated. A powder butterfly valve 7 is fixedly mounted at the bottom discharge port of the tank 3. The powder butterfly valve 7 closes when the tank 3 is rotated. The bottom plate 1 is also equipped with a conveying mechanism 8 and a docking mechanism 9. After the powder is fully mixed in the tank 3, the conveying mechanism 8 is connected to the powder butterfly valve 7 through the docking mechanism 9. When the powder butterfly valve 7 is opened, the evenly mixed powder can enter the conveying mechanism 8 from the tank 3. The docking mechanism 9 is also equipped with a cleaning mechanism 10. The output end of the cleaning mechanism 10 is close to the bottom wall of the tank 3 and is used to vibrate and clean the inner wall of the tank 3.

[0037] Please see Figure 2As shown, in this embodiment, an outer connecting sleeve 11 is fixedly embedded at the same position on both support plates 2. Please refer to... Figure 3 As shown, a connecting pipe 12 is rotatably installed inside the outer connecting sleeve 11 via a bearing. Both connecting pipes 12 are fixedly connected to the tank body 3. A second bevel gear 13 is fixedly installed at the outer end of the connecting pipe 12 near the drive mechanism 5. The second bevel gear 13 is connected to the drive mechanism 5. The drive mechanism 5 drives the second bevel gear 13 to rotate the corresponding connecting pipe 12. The rotating connecting pipe 12 drives the tank body 3 to rotate synchronously, so that the tank body 3 can rotate and flip between the two support plates 2.

[0038] Please see Figure 2 As shown, in this embodiment, the stirring component 4 includes a stirring rod 41 that passes through the tank 3 and is rotatably connected between two connecting pipes 12 via bearings. One end of the stirring rod 41 near the second bevel gear 13 is fixedly connected to a first bevel gear 42, which is connected to the drive mechanism 5. At least two sets of stirring blades 43 are also provided on the stirring rod 41, arranged at different angles. When the drive mechanism 5 drives the second bevel gear 13 to rotate, the drive mechanism 5 also simultaneously drives the first bevel gear 42 to rotate in the opposite direction. The rotating first bevel gear 42 causes the stirring rod 41 to rotate within the tank 3, and the stirring blades 43 on the stirring rod 41 mix the powder in the tank 3 evenly.

[0039] In this invention, the tank 3 and the stirring element 4 rotate in opposite directions simultaneously. When the tank 3 flips, the powder is repeatedly aggregated and separated under the action of gravity and centrifugal force. At the same time, the stirring rod 41 rotating in opposite directions inside the tank 3 drives the stirring blade 43 to directly stir the powder, so that the powder is fully and evenly mixed.

[0040] Please see Figure 2 As shown, in this embodiment, the drive mechanism 5 includes a servo motor 51 fixedly mounted on the corresponding support plate 2, a reduction gearbox 52 fixedly mounted on the output shaft end of the servo motor 51, and a transmission bevel gear 53 fixedly mounted on the output shaft end of the reduction gearbox 52. The first bevel gear 42 and the second bevel gear 13 are both meshed with the transmission bevel gear 53. The servo motor 51 drives the transmission bevel gear 53 to rotate, and the rotating transmission bevel gear 53 drives the first bevel gear 42 and the second bevel gear 13 to rotate in opposite directions at the same time, thereby realizing the simultaneous opposite rotation of the tank body 3 and the stirring rod 41.

[0041] Please see Figure 1 As shown, in this embodiment, a cover 14 is installed on the support plate 2 on which the drive mechanism 5 is installed, and the cover 14 protects the drive mechanism 5, the first bevel gear 42 and the second bevel gear 13.

[0042] Please see Figure 5As shown, in this embodiment, the feeding mechanism 8 includes a feeding pipe 81 fixed to the top of the base plate 1, a spiral blade shaft 82 rotatably installed inside the feeding pipe 81, and a drive motor 83 fixedly installed at one end of the feeding pipe 81 with its output shaft fixedly connected to the spiral blade shaft 82. The drive motor 83 drives the spiral blade shaft 82 to rotate, thus pushing out the uniformly mixed powder.

[0043] Please see Figure 3-6 As shown, in this embodiment, the docking mechanism 9 includes a docking pipe 91 fixed to the bottom of the powder butterfly valve 7, a fixed pipe 92 installed at the top of the feed inlet of the conveying pipe 81, a movable pipe 93 slidably connected inside the fixed pipe 92, a docking seat 94 fixed to the top of the movable pipe 93, at least two movable plates 95 fixedly installed on the outer periphery of the docking seat 94, and a lifting assembly disposed on one side of the movable plate 95. The lifting assembly includes a mounting bracket 96 fixed to the top of the base plate 1, a hydraulic push rod 97 fixedly installed on the mounting bracket 96 with its telescopic end fixedly connected to the corresponding movable plate 95, and a guide rail 98 fixedly installed on the mounting bracket 96 and slidably connected to the movable plate 95.

[0044] The extension and retraction of the hydraulic push rod 97 drives the docking seat 94 to dock and separate from the docking pipe 91. At the same time, the docking seat 94 drives the moving pipe 93 to slide inside the fixed pipe 92, ensuring that the powder can be smoothly transported from the tank 3 to the conveying pipe 81.

[0045] It should be noted that the bottom cross-section of the connecting pipe 91 has a funnel-shaped inclined structure, and the interior of the docking seat 94 has a funnel-shaped inclined structure that matches the shape of the connecting pipe 91. This allows the docking seat 94 to align with the connecting pipe 91 when it moves upward, and the docking seat 94 is fitted onto the outside of the connecting pipe 91 to fix the position of the tank 3, facilitating material discharge. Furthermore, a sealing ring can be installed on the contact surface between the connecting pipe 91 and the docking seat 94, and the moving pipe 93 is connected to the conveying pipe 81 through the fixed pipe 92. The sealing ring ensures a tight seal when the connecting pipe 91 and the docking seat 94 are connected, preventing powder leakage.

[0046] This utility model utilizes the extension and retraction of the hydraulic push rod 97 to drive the docking seat 94 and the docking pipe 91 to dock and separate. At the same time, the moving pipe 93 and the fixed pipe 92 transport the powder to the conveying pipe 81, thereby realizing the powder receiving function of this device and achieving the closed conveying of the ultra-early strength agent. This effectively avoids dust caused by the early strength agent scattering or flying during the discharge process, thereby improving the working environment and protecting the health of the operators.

[0047] Please see Figure 2 and Figure 6As shown, in this embodiment, the cleaning mechanism 10 is provided with at least two sets. The cleaning mechanism 10 includes a fixed frame 101 fixed to the top of the corresponding moving plate 95, support springs 102 fixedly installed on both sides of the top of the fixed frame 101, a contact plate 103 fixedly installed on the top of the support springs 102, and an electromagnetic vibrator 104 fixedly installed at the bottom of the contact plate 103. The contact plate 103 is pushed to contact the tank wall 3 by the hydraulic push rod 97. The contact plate 103 transmits the vibration of the electromagnetic vibrator 104, causing the powder adhering to the tank wall 3 to separate and fall due to the vibration. The upper surface shape of the contact plate 103 matches the lower surface shape of the tank 3, and the contact plates 103 are symmetrically distributed on the vertical center line of the tank 3. Through the technical solution, it is ensured that the contact plate 103 can transmit the vibration evenly and effectively to the tank wall 3.

[0048] This invention uses a hydraulic push rod 97 to push the contact plate 103 into contact with the silo wall of the tank 3, and transmits the vibration of the electromagnetic vibrator 104, causing the powder adhering to the silo wall to separate and fall due to the vibration. This realizes the vibration cleaning function of the device, effectively preventing the material from adhering and accumulating on the silo wall, ensuring a smooth and unobstructed feeding process, and improving feeding efficiency.

[0049] The working principle of this utility model:

[0050] The contact plate 103 is separated from the tank wall of the tank body 3 by moving the hydraulic push rod 97 downward, and the docking seat 94 is separated from the docking pipe 91.

[0051] Open the cap 6 and pour the proportioned powder into the tank 3. Seal the tank 3 with the cap 6. Start the servo motor 51, which drives the transmission bevel gear 53 to rotate through the reduction gearbox 52. The transmission bevel gear 53 drives the second bevel gear 13 and the first bevel gear 42 to rotate in opposite directions. The second bevel gear 13 drives the tank 3 to rotate through the connecting pipe 12. Through the action of gravity and centrifugal force, the powder in the tank 3 is repeatedly aggregated and separated. At the same time, the first bevel gear 42 drives the stirring rod 41 to rotate inside the tank 3, directly stirring the powder to make the powder evenly mixed.

[0052] After mixing is completed, once the tank 3 stops rotating, the hydraulic push rod 97 moves upward to make the contact plate 103 fit tightly against the wall of the tank 3, and to make the docking seat 94 connect with the docking pipe 91. By opening the powder butterfly valve 7, the powder inside the tank 3 is transported to the conveying pipe 81 through the moving pipe 93 and the fixed pipe 92. The drive motor 83 is started to drive the spiral blade shaft 82 to rotate, pushing out the powder. At the same time, the contact plate 103 transmits the vibration of the electromagnetic vibrator 104 to vibrate the wall of the tank 3, causing the powder adhering to the wall to separate and fall due to the vibration, ensuring a smooth and unobstructed feeding process.

[0053] The preferred embodiments of this utility model have been described in detail above and should not be considered as limiting the scope of this utility model. All equivalent changes and improvements made within the scope of the claims of this utility model should still fall within the patent coverage of this utility model.
