Abstract
Description
Technical Field
[0001] This application relates to the technical field of water-reducing agent preparation, and in particular to a mixing and stirring device for cement water-reducing agents. Background Technology
[0002] Cement water-reducing agent is an additive used in the production of concrete. It can reduce the amount of water required during the preparation of concrete while maintaining the fluidity of the concrete.
[0003] In the production process of cement water-reducing agents, the raw materials need to be mixed to ensure a full reaction and obtain a qualified cement water-reducing agent. The existing production process involves placing the raw materials in a mixing tank, adding the raw materials and water, and then mixing the mixture using a stirring rod coaxially mounted with the mixing tank.
[0004] In the existing production process of cement water-reducing agents, the mixing rod can often only be fixed in a horizontal position to rotate and mix. During the mixing process, the water-reducing agent raw materials are prone to stratification. A large amount of water-reducing agent raw materials settle at the bottom of the mixing tank, resulting in low mixing efficiency and low production efficiency of the water-reducing agent. Utility Model Content
[0005] To accelerate the mixing efficiency and production efficiency of water-reducing agents, this application provides a cement water-reducing agent mixing and stirring device.
[0006] The cement water-reducing agent mixing and stirring device provided in this application adopts the following technical solution:
[0007] A cement water-reducing agent mixing and stirring device, comprising:
[0008] The mixing tank has an internal mixing chamber.
[0009] A mixing mechanism, arranged inside the stirring chamber, includes a mixing claw, a mixing motor, and a liquid return component. The mixing motor is fixedly connected to the inner wall of the stirring chamber, the mixing claw is connected to the output shaft of the mixing motor, and the liquid return component is connected to the mixing claw. The liquid return component passes through the bottom end and the top end of the stirring chamber.
[0010] A drainage mechanism is provided, which is connected to the bottom of the mixing chamber and is used to drain the cement water-reducing agent inside the mixing chamber.
[0011] By adopting the above technical solution, when mixing the water-reducing agent, the mixing mechanism drives the mixing claw to rotate through the mixing motor. When the mixing claw rotates, it mixes the water-reducing agent raw materials in the mixing tank. While the mixing claw rotates and mixes the water-reducing agent in the mixing tank, the mixing claw drives the liquid return component to pass through the bottom and top of the mixing chamber. The liquid return component carries the liquid from the bottom of the mixing chamber to the top of the mixing chamber, reducing the stratification phenomenon of the water-reducing agent raw materials in the mixing chamber, making the water-reducing agent more thoroughly mixed. The mixed water-reducing agent is discharged from the liquid discharge mechanism to form the finished water-reducing agent, which ultimately speeds up the mixing efficiency of the water-reducing agent and accelerates the production efficiency of the water-reducing agent.
[0012] Optionally, the mixing motor is connected to the side wall of the mixing chamber, and the mixing claw is inclinedly arranged inside the mixing chamber.
[0013] By adopting the above technical solution, the mixing claws are arranged at an angle so that when the mixing motor drives the mixing claws, the direction of the mixing claws intersects with the direction of gravity, making the water-reducing agent raw materials in the mixing chamber more thoroughly mixed.
[0014] Optionally, the hybrid claw includes a central rod and several claw bars, one end of the central rod is fixedly connected to the output shaft of the hybrid motor, and one end of each of the several claw bars is fixedly connected to the end of the central rod opposite to the hybrid motor.
[0015] By adopting the above technical solution, the mixing claw is connected to the mixing motor through a central rod, thereby transmitting the power of the mixing motor to the claw rod, which mixes the water-reducing agent raw materials in the mixing chamber by rotating.
[0016] Optionally, a resistance-increasing component is connected to the claw bar, and the direction of the resistance-increasing component is perpendicular to the rotation direction of the claw bar.
[0017] By adopting the above technical solution, the resistance-increasing component increases the contact area between the mixing mechanism and the water-reducing agent raw material, thereby facilitating the mixing mechanism to stir the water-reducing agent raw material in the mixing chamber, and making the water-reducing agent raw material more thoroughly stirred.
[0018] Optionally, the arrangement direction of the resistance-increasing components connected to different claw bars may vary.
[0019] By adopting the above technical solution, the different resistance-increasing components arranged on the claw bar in different directions guide the water-reducing agent to move in different directions when the claw bar rotates at the same position, making the liquid flow of the water-reducing agent in the mixing chamber more turbulent and the mixing of the water-reducing agent more thorough.
[0020] Optionally, the liquid return component includes a connecting rod and a liquid arc plate, one end of the connecting rod is connected to a claw rod, and the liquid arc plate is connected to the end of the connecting rod opposite to the claw rod.
[0021] By adopting the above technical solution, the liquid return component drives the liquid-carrying arc plate to move through the connecting arc rod. When the liquid-carrying arc plate moves to the bottom of the mixing chamber, it encapsulates the water-reducing agent at the bottom of the mixing chamber. When the liquid-carrying arc plate moves to the top of the mixing chamber, it pours the encapsulated water-reducing agent onto the mixing claw. The mixing claw disperses the poured water-reducing agent, thus accelerating the mixing of the water-reducing agent.
[0022] Optionally, the liquid arc plate has a recess in the middle along the direction of movement.
[0023] By adopting the above technical solution, the concave part of the liquid arc plate allows the water-reducing agent to be encapsulated when the liquid arc plate moves to the bottom of the mixing chamber.
[0024] Optionally, the liquid arc plate is hinged to the connecting rod, and a swing limiter is connected at the connection between the connecting rod and the liquid arc plate.
[0025] By adopting the above technical solution, the swing limiter limits the movement of the liquid arc plate, restricts the rotation amplitude of the liquid arc plate, and reduces the probability that the liquid arc plate fails to encapsulate the water-reducing agent at the bottom of the mixing chamber.
[0026] Optionally, the swing amplitude limiter includes a first limiting plate and a second limiting plate. The first limiting plate is located on the side of the liquid arc plate facing the cavity wall of the stirring chamber, and the second limiting plate is located on the side of the liquid arc plate away from the cavity wall of the stirring chamber. The first limiting plate is arranged parallel to the connecting rod, and the angle formed by the first limiting plate and the second limiting plate for clamping the liquid arc plate is an acute angle.
[0027] By adopting the above technical solution, the first limiting plate and the second limiting plate respectively limit the maximum angle of the liquid arc plate moving into the mixing chamber along the rotation direction. When the liquid arc plate moves to the bottom of the mixing chamber, it encapsulates the water-reducing agent at the bottom of the mixing chamber. When the liquid arc plate moves to the top of the mixing chamber, it rotates, which makes it easier for the liquid arc plate to pour the encapsulated water-reducing agent onto the mixing claw, so that the water-reducing agent is mixed more thoroughly.
[0028] Optionally, the drainage mechanism includes several liquid distribution valves, and several liquid distribution ports are opened at the bottom of the stirring chamber, with the liquid distribution valves arranged in the liquid distribution ports.
[0029] By adopting the above technical solution, the drainage mechanism controls the opening and closing of the liquid distribution valve, so that the water-reducing agent that has been stirred can flow out from different liquid distribution ports for storage.
[0030] Compared with the prior art, this application includes at least one of the following beneficial technical effects:
[0031] 1. During the mixing of the water-reducing agent, the mixing motor in the mixing mechanism drives the mixing claw to rotate. The rotation of the mixing claw mixes the water-reducing agent raw materials in the mixing chamber of the mixing tank. When the mixing claw rotates, it simultaneously drives the return liquid component to rotate. The return liquid component passes through the bottom and top of the mixing chamber, thereby carrying the mixed liquid at the bottom of the mixing chamber to the top of the mixing chamber, reducing the probability of stratification of the water-reducing agent mixed raw materials in the mixing chamber. After the water-reducing agent is mixed, the finished water-reducing agent is discharged from the draining mechanism, which ultimately speeds up the mixing efficiency of the water-reducing agent and the production efficiency of the water-reducing agent.
[0032] 2. The mixing claws are inclinedly arranged inside the mixing tank. With the help of gravity, the mixing claws are tangential to gravity, which makes the water-reducing agent raw materials in the mixing chamber more disordered, so that the water-reducing agent in the mixing tank is mixed more thoroughly.
[0033] 3. The resistance-increasing components arranged on the claw bars of the mixing claw increase the contact area between the mixing mechanism and the water-reducing agent raw material, allowing the water-reducing agent raw material to be mixed more thoroughly. The resistance-increasing components connected to different claw bars are arranged in different directions, making the water-reducing agent raw material mixture in the mixing chamber more turbulent, resulting in more thorough mixing of the water-reducing agent and accelerating the mixing efficiency of the water-reducing agent.

Detailed Implementation
[0038] The following is in conjunction with the appendix Figures 1-3 This application will be described in further detail.
[0039] This application discloses a cement water-reducing agent mixing and stirring device. (Refer to...) Figure 1 and Figure 2 A cement water-reducing agent mixing device includes a mixing tank 1, a mixing mechanism 2, and a draining mechanism 3.
[0040] A stirring chamber 11 is provided inside the stirring tank 1. A mixing mechanism 2 is arranged inside the stirring chamber 11. The mixing mechanism 2 includes a mixing claw 21, a mixing motor 22, and a liquid return component 23. The mixing motor 22 is fixedly connected to the inner wall of the stirring chamber 11. The mixing claw 21 is fixedly connected to the output shaft of the mixing motor 22. The liquid return component 23 is connected to the mixing claw 21 and passes through the bottom and top of the stirring chamber 11. The liquid discharge mechanism 3 connects the bottom of the stirring chamber 11 to the outside.
[0041] When mixing the water-reducing agent raw materials, the mixing motor 22 in the mixing mechanism 2 drives the mixing claw 21 to rotate in the mixing chamber 11 of the mixing tank 1, thereby mixing the water-reducing agent raw materials in the mixing tank 1. During the movement of the mixing claw 21, it drives the liquid return component 23 to move from the bottom end of the mixing chamber 11 to the top end of the mixing chamber 11, thereby mixing the water-reducing agent raw materials that have settled at the bottom end of the mixing chamber 11 due to gravity, reducing the phenomenon of stratification of the water-reducing agent raw materials in the mixing chamber 11, and making the mixing of the water-reducing agent raw materials more thorough. Then, the liquid discharge mechanism 3 discharges the water-reducing agent, which ultimately speeds up the mixing efficiency of the water-reducing agent and the production efficiency of the water-reducing agent.
[0042] Reference Figure 2 The mixing motor 22 is inclinedly arranged inside the mixing chamber 11, and the fixed end of the mixing motor 22 is fixedly connected to the bottom of the mixing chamber 11. The bottom of the mixing chamber 11 is inclined.
[0043] The obliquely arranged mixing motor 22 drives the mixing claw 21 to be obliquely arranged in the mixing chamber 11. When the mixing claw 21 rotates, it forms an oblique angle with the gravity of the water-reducing agent raw material in the mixing chamber 11, so that the mixing claw 21 can reduce the stratification phenomenon caused by gravity when mixing the water-reducing agent raw material in the mixing chamber 11.
[0044] Reference Figure 2 The mixing claw 21 includes a central rod 211 and several claw rods 212. One end of the central rod 211 is fixedly connected to the output shaft of the mixing motor 22, and the other end of the central rod 211 is connected to the claw rods 212.
[0045] The mixing claw 21 uses several claw rods 212 to stir the water-reducing agent raw materials at different positions. The concentrating rod 211 concentrates one end of the claw rods 212, thereby transmitting the power of the mixing motor 22 to all the claw rods 212, driving the claw rods 212 to move and thus stirring the water-reducing agent raw materials.
[0046] Reference Figure 2 A resistance-increasing component 213 is connected to the claw bar 212. The arrangement direction of the resistance-increasing component 213 is perpendicular to the rotation direction of the claw bar 212. The arrangement direction of the resistance-increasing component 213 connected to different claw bars 212 is different.
[0047] The resistance-increasing element 213 arranged on the claw bar 212 increases the contact area between the claw bar 212 and the water-reducing agent raw material in the mixing chamber 11 when the claw bar 212 moves, thereby enabling the water-reducing agent raw material to be mixed more evenly. The resistance-increasing element 213 on different claw bars 212 are arranged in different directions, which can drive the water-reducing agent raw material to different positions in the mixing chamber 11 when the claw bar 212 moves, increasing the degree of disorder of the water-reducing agent raw material in the mixing chamber 11, thereby making the water-reducing agent raw material more thoroughly mixed and accelerating the production efficiency of the water-reducing agent.
[0048] Reference Figure 2 and Figure 3 The liquid return component 23 includes a connecting rod 231 and a liquid arc plate 232. One end of the connecting rod 231 is fixedly connected to a claw rod 212, and the other end of the connecting rod 231 is hinged to the liquid arc plate 232. A recess is provided in the middle of the liquid arc plate 232 along the direction of movement. A swing limiter 4 is provided at the hinge of the connecting rod 231 and the liquid arc plate 232. The swing limiter 4 includes a first limit plate 41 and a second limit plate 42. The first limit plate 41 is located on one side of the liquid arc plate 232, and the second limit plate 42 is located on the other side of the liquid arc plate 232. The first limit plate 41 and the second limit plate 42 clamp the liquid arc plate 232.
[0049] Reference Figure 2 and Figure 3 The return component 23 is connected to the claw rod 212 via the connecting rod 231, causing the claw rod 212 to move and drive the liquid-carrying arc plate 232. The liquid-carrying arc plate 232 passes between the bottom and top of the mixing chamber 11, and through the recess in the middle of the liquid-carrying arc plate 232, it carries more water-reducing agent material from the bottom of the mixing chamber 11 to the top of the mixing chamber 11, making the water-reducing agent material in the mixing chamber 11 more evenly mixed. The swing limiter 4 limits the rotation direction of the liquid-carrying arc plate 232, so that when the liquid-carrying arc plate 232 rotates to the bottom of the mixing chamber 11, it can carry out the water-reducing agent material from the bottom of the mixing chamber 11 at a more suitable angle, and when the liquid-carrying arc plate 232 rotates to the top of the mixing chamber 11, it can spill out the water-reducing agent material carried by the liquid-carrying arc plate 232 at a more suitable angle, thereby facilitating the mixing of the water-reducing agent material by the mixing claw 21. The first limiting plate 41 limits the maximum rotation angle of one side of the liquid arc plate 232, and the second limiting plate 42 limits the maximum rotation angle of the other side of the liquid arc plate 232, thereby limiting the rotation range of the liquid arc plate 232.
[0050] Reference Figure 1 and Figure 2 The drainage mechanism 3 includes several liquid distribution valves 31, and several liquid distribution ports 12 are opened at the bottom of the stirring chamber 11. The liquid distribution valves 31 are arranged in the liquid distribution ports 12 to control the communication between the bottom of the stirring chamber 11 and the outside.
[0051] The draining mechanism 3 discharges the water-reducing agent raw materials that have been stirred in different dispensing ports 12 through the dispensing valve 31, so that the water-reducing agent can flow out from different dispensing ports 12, reducing the probability that the water-reducing agent raw materials will accumulate in one dispensing port 12 and cause uneven mixing of the water-reducing agent.
[0052] The implementation principle of the cement water-reducing agent mixing and stirring device in this application embodiment is as follows: When mixing water-reducing agent raw materials to make water-reducing agent, the mixing motor 22 of the mixing mechanism 2 drives the mixing claw 21 to move. The mixing claw 21 mixes the water-reducing agent raw materials in the mixing chamber 11 to achieve the mixing of water-reducing agent raw materials. When the mixing claw 21 moves, it synchronously drives the return liquid component 23 to move. The return liquid component 23 transports the water-reducing agent raw materials at the bottom of the mixing chamber 11 to the top of the mixing chamber 11, thereby making the mixing of water-reducing agent raw materials more thorough and accelerating the mixing of water-reducing agent raw materials. Finally, the mixed water-reducing agent is discharged from the discharge mechanism 3, thereby achieving the effect of accelerating the mixing efficiency of water-reducing agent and accelerating the production efficiency of water-reducing agent.
[0053] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
