Description

Technical Field

[0001] This utility model relates to the field of concrete processing technology, specifically to a reaction vessel for concrete additives. Background Technology

[0002] Concrete additives, or admixtures for short, are substances used to improve the performance of concrete. A reaction vessel is a container for physical or chemical reactions. Through the structural design and parameter configuration of the vessel, the heating, evaporation, cooling, and low-to-high-speed mixing functions required by the process can be achieved. Concrete additives need to be manufactured using a reaction vessel during the production process. However, the viscosity of existing concrete additives varies greatly, and it is difficult to ensure that materials of different viscosities can be uniformly mixed using a fixed-structure stirring device. For example, CN219784761U discloses a reaction vessel for producing concrete additives, belonging to the technical field of additive production equipment. It includes a reaction tank connected to a motor, a feed pipe connected to the outside of the reaction tank, a metering structure connected to the outside of the reaction tank, the feed pipe connected to the metering structure, a cleaning structure connected inside the reaction tank, a cleaning plate attached inside the reaction tank, and a fixing sleeve connected inside the cleaning plate. This reaction vessel for producing concrete additives, by setting up a reaction tank, cleaning structure, cleaning plate, fixing sleeve, and rotating rod, allows the cleaning plate to reciprocate within the reaction tank through the cooperation of the limiting groove, the sleeve plate, and the limiting rod. This enables the cleaning plate to clean the additives adhering to the inner wall of the reaction vessel, preventing damage to the reaction vessel caused by long-term additive accumulation. However, there are shortcomings: In the actual production scenario of concrete additives, the viscosity of different types of materials varies significantly. From low-viscosity liquid water-reducing agents to high-viscosity powdered quick-setting agents, their physical properties vary greatly. For low-viscosity liquid materials, the fixed stirring paddle is prone to insufficient convection due to insufficient rotation speed. For high-viscosity powdered or paste materials, the fixed structure is difficult to break up agglomerates due to insufficient shear force. Utility Model Content

[0003] The purpose of this invention is to provide a reaction vessel for concrete additives, in order to solve the problem mentioned in the background art that the consistency of concrete additives varies greatly, and it is difficult to ensure that materials of different viscosities can be uniformly stirred by using a fixed-structure stirring device.

[0004] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model relates to a reaction vessel for concrete additives, comprising a vessel body. An adjustment mechanism is fixedly connected to the inner cavity of the vessel body. The adjustment mechanism includes a top plate, a connecting shaft 1 rotatably connected to the bottom end of the top plate, a connecting column 1 fixedly connected to the bottom end of the connecting shaft 1, a connecting shaft 2 fixedly connected to the inner cavity of the connecting column 1, a motor 2 fixedly connected to the bottom end of the connecting shaft 2, a connecting shaft 3 rotatably connected to the bottom end of the motor 2, a connecting column 2 fixedly connected to the outer side of the connecting shaft 3, a connecting shaft 4 fixedly connected to the bottom end of the connecting column 2, and an adjustment column rotatably connected to the bottom end of the connecting shaft 4.

[0005] Furthermore, a fixed column is fixedly connected to the outer side of the second motor, and a connecting column three is rotatably connected to one end of the fixed column. An adjusting shaft is rotatably connected to the inner cavity of the connecting column three, and the connecting column three is rotatably connected to the adjusting column through the adjusting shaft.

[0006] Furthermore, a drive shaft is fixedly connected to the bottom end of the adjusting column, and a helical blade is rotatably connected to the bottom end of the drive shaft.

[0007] Furthermore, a power assembly is fixedly connected to one end of the vessel body. The power assembly includes a motor, which is fixedly mounted on one side of the vessel body. An output pipe is fixedly connected to the top of the motor, and a fixing head is fixedly connected to one end of the output pipe. The output pipe is connected to the top plate through the fixing head.

[0008] Furthermore, a feed inlet is fixedly connected to the top of the vessel body, and a feed groove is provided in the inner cavity of the feed inlet, which extends through the inner cavity of the vessel body.

[0009] Furthermore, a discharge port is fixedly connected to the bottom end of the vessel body, and a discharge channel communicating with the inner cavity of the vessel body is opened at the top of the inner cavity of the discharge port. A baffle assembly for manually controlling the flow of materials is provided in the inner cavity of the vessel body corresponding to the discharge channel.

[0010] This utility model has the following beneficial effects: I. This utility model is equipped with an adjustment mechanism. Under the action of motor one, the power is transmitted to connecting column one through connecting shaft two, causing connecting column one to rotate around connecting shaft one. Then, while connecting column one rotates, it drives motor two to make eccentric motion along connecting shaft one. Motor two drives connecting column two to rotate through connecting shaft three. Connecting column two then drives adjustment column to rotate through connecting shaft four. During the rotation of adjustment column, adjustment column is rotatably connected to connecting column three through adjustment shaft, thereby generating circumferential motion. Finally, it drives the spiral blade to adjust and stir in multiple directions. Through the adjustment mechanism, the spiral blade is driven to continuously adjust the stirring position inside the kettle, shortening the overall mixing time and improving the stirring uniformity. II. Based on the above-mentioned beneficial effects, a power assembly is also provided. The user can directly feed the additive into the middle of the reactor body through the inlet by gravity or pumping, avoiding the material from adhering to the side wall of the reactor body. Then, the first motor is turned on. The first motor drives the output pipe and the fixed head and the top plate to rotate the first connecting shaft. In turn, the first connecting shaft drives the first connecting column to rotate, which in turn drives the bottom adjustment structure to make an eccentric movement. After the reaction is completed, the user can manually operate the baffle assembly (such as the translation or rotation of the baffle) to open the discharge channel. The material is discharged from the discharge port under the action of gravity. After the discharge is completed, the baffle is closed to achieve sealing. Attached Figure Description

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0016] Please see Figure 1-5 As shown, this utility model is a reaction vessel for concrete additives, including a vessel body 1. An adjustment mechanism 3 is fixedly connected to the inner cavity of the vessel body 1. The adjustment mechanism 3 includes a top plate 31. A connecting shaft 32 is rotatably connected to the bottom end of the top plate 31. A connecting column 33 is fixedly connected to the bottom end of the connecting shaft 32. A connecting shaft 34 is fixedly connected to the inner cavity of the connecting column 33. A motor 35 is fixedly connected to the bottom end of the connecting shaft 34. A connecting shaft 36 is rotatably connected to the bottom end of the motor 35. A connecting column 37 is fixedly connected to the outer side of the connecting shaft 36. A connecting shaft 38 is fixedly connected to the bottom end of the connecting column 37. An adjustment column 39 is rotatably connected to the bottom end of the connecting shaft 38. Specifically, motor 235 adopts a geared motor with a power of 2.2kW, a speed of 60rpm, and a torque of 200N·m. Motor 235 achieves "low speed and high torque" output through the gear reduction structure. Together with the mechanical connection of the adjustment mechanism 3, it forms a composite motion mixing system. Its 2.2kW power, 60rpm speed and 200N·m torque parameters match the mixing requirements of concrete additives, taking into account both mixing efficiency and equipment stability. For example, the top plate 31 serves as a fixed support for the adjustment mechanism 3. It is rotatably connected to the connecting column 33 via the connecting shaft 32 to form a vertical transmission path. Under the action of the motor 21, the power is transmitted to the connecting column 33 via the connecting shaft 34, causing the connecting column 33 to rotate around the connecting shaft 32. Then, while the connecting column 33 rotates, it drives the motor 35 to make an eccentric motion along the connecting shaft 32. The motor 35 drives the connecting column 37 to rotate via the connecting shaft 36, and the connecting column 37 then drives the adjustment column 39 to rotate via the connecting shaft 38.

[0017] A fixing post 310 is fixedly connected to the outside of motor 2 35. One end of the fixing post 310 is rotatably connected to a connecting post 311. An adjusting shaft 312 is rotatably connected to the inner cavity of the connecting post 311. The connecting post 311 is rotatably connected to the adjusting post 39 through the adjusting shaft 312. For example, during the rotation of the adjusting column 39, the adjusting column 39 is rotatably connected to the connecting column 311 via the adjusting shaft 312, thereby generating a rotating circular motion, which ultimately drives the spiral blade 314 to adjust and stir in multiple directions.

[0018] The bottom end of the adjusting column 39 is fixedly connected to the drive shaft 313, and the bottom end of the drive shaft 313 is rotatably connected to the spiral blade 314. Specifically, the lower half of the spiral blade 314 adopts a smaller pitch design, while the upper half adopts a larger pitch structure. The smaller pitch structure of the lower half increases the contact area of ​​the blades per unit length by shortening the axial spacing of the blades, which generates stronger shearing and lifting forces on the high-concentration, easily deposited concrete additives at the bottom of the vessel 1, preventing material accumulation and clumping. It is especially suitable for the initial mixing stage of powdered materials and liquid additives. The larger pitch design of the upper half reduces the resistance during the material's ascent by increasing the axial spacing of the blades, allowing the low-viscosity material in the upper part to quickly form an axial convection circulation. Combined with the revolution of the adjustment mechanism 3, it can shorten the overall mixing time and improve the uniformity of mixing. For example, the spiral blade 314 is connected to the adjusting column 39 via the drive shaft 313, and the spiral blade 314 continuously stirs the material in the inner cavity of the vessel 1 under the action of the drive shaft 313.

[0019] Working principle: Under the action of motor 21, the power is transmitted to connecting column 33 through connecting shaft 34, which drives connecting column 33 to rotate around connecting shaft 32. Then, while connecting column 33 rotates, it drives motor 35 to make eccentric motion along connecting shaft 32. Motor 35 drives connecting column 37 to rotate through connecting shaft 36. Connecting column 37 then drives adjusting column 39 to rotate through connecting shaft 4 38. During the rotation of adjusting column 39, adjusting column 39 is rotatably connected to connecting column 311 through adjusting shaft 312, thereby generating a rotating circular motion, which ultimately drives the spiral blade 314 to adjust and stir in multiple directions.

[0020] In this step, the adjusting mechanism 3 drives the spiral blades 314 to continuously adjust the stirring position inside the vessel body 1, thereby shortening the overall mixing time and improving the uniformity of stirring.

[0021] Please see Figure 1-3 As shown, this embodiment, based on the above embodiment, further includes a power component 2. A power assembly 2 is fixedly connected to one end of the vessel body 1. The power assembly 2 includes a motor 21. The motor 21 is fixedly installed on one side of the vessel body 1. An output pipe 22 is fixedly connected to the top of the motor 21. A fixing head 23 is fixedly connected to one end of the output pipe 22. The output pipe 22 is connected to the top plate 31 through the fixing head 23. Specifically, motor 21 is a variable frequency motor with a power of 1.5kW, a speed of 1000rpm, and a torque of 15N·m. After motor 21 is started, the output pipe 22 drives the top plate 31 to rotate at a constant speed around the central axis of the vessel body 1, thereby driving the connecting shaft 32, the connecting column 33, and the motor 35 to rotate synchronously in a circular orbit, so that the stirring trajectory of the spiral blade 314 covers the entire area of ​​the inner cavity of the vessel body 1. For example, motor 21 drives connecting shaft 32 to rotate via output pipe 22 and fixed head 23 and top plate 31, and then drives connecting column 33 to rotate via connecting shaft 32, while driving bottom adjustment structure to make eccentric movement.

[0022] The top of the vessel body 1 is fixedly connected to the inlet 4, and the inner cavity of the inlet 4 is provided with an inlet groove that runs through the inner cavity of the vessel body 1. For example, the feed trough serves as a material channel, extending through the feed inlet 4 and the top of the vessel body 1, so that powdered or liquid additives can fall directly into the middle of the vessel body 1 by gravity or pumping, thus preventing the material from adhering to the side wall of the vessel body 1.

[0023] The bottom end of the vessel body 1 is fixedly connected to the discharge port 5. The top of the inner cavity of the discharge port 5 is provided with a discharge channel communicating with the inner cavity of the vessel body 1. The inner cavity of the vessel body 1 is provided with a baffle assembly for manually controlling the flow of materials at the discharge channel. Specifically, the baffle assembly consists of a baffle body, an operating handle, a guide rail, and a limit buckle. The baffle body is made of stainless steel flat plate or arc plate with sealing strips on the edges. Its size matches the diameter of the discharge channel. The operating handle is fixedly connected to the baffle body and extends to the outside of the vessel body 1. The surface is provided with anti-slip texture. The guide rail is fixed to the inner wall of the vessel body 1 and cooperates with the grooves on both sides of the baffle body to form a linear sliding guide structure. The limit buckle is located at both ends of the guide rail (open position and closed position) and fixes the position of the baffle by a slot or spring pin. In the closed state, the baffle body completely covers the inlet of the discharge channel, and the sealing strip is tightly fitted with the edge of the discharge channel to form a mechanical seal. When discharge is required, the user pulls the baffle with the handle to completely remove it from the inlet of the discharge channel and expose the material flow section. For example, the discharge channel connects the inner cavity of the vessel body 1 with the discharge port 5. Under normal conditions, it is closed by the baffle assembly to prevent material leakage. When the reaction is completed, the discharge channel is opened by manually operating the baffle assembly (such as translating or rotating the baffle), and the material is discharged from the discharge port 5 under the action of gravity. After the unloading is completed, the baffle is closed to achieve sealing.

[0024] Working principle: The user feeds the additive directly into the middle of the reactor body 1 through the inlet 4 by gravity or pumping, avoiding the material from adhering to the side wall of the reactor body 1. Then, the user turns on the motor 21. The motor 21 drives the output pipe 22 and the fixed head 23 and the top plate 31 to rotate the connecting shaft 32. In turn, the connecting shaft 32 drives the connecting column 33 to rotate, which in turn drives the bottom adjustment structure to make an eccentric movement. After the reaction is completed, the user opens the discharge channel by manually operating the baffle assembly (such as translating or rotating the baffle). The material is discharged from the discharge port 5 under the action of gravity. After the discharge is completed, the baffle is closed to achieve a seal.

These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification.
