Description

Technical Field

[0001] This utility model relates to the technical field, specifically to a concrete water-reducing agent production device. Background Technology

[0002] Water-reducing agents are concrete admixtures that reduce the amount of mixing water while maintaining a relatively constant concrete slump. Most are anionic surfactants, including lignin sulfonates, naphthalene sulfonate formaldehyde polymers, etc.

[0003] Chinese patent document CN201820210121.2 discloses a concrete water-reducing agent production device. This device includes a reaction chamber, a solid material inlet and a liquid material feed hopper at the top of the reaction chamber, a discharge outlet at the bottom of the reaction chamber, a stirring mechanism, an electromagnetic heating coil, a temperature sensor, and a temperature controller. The reaction chamber comprises an inner shell and an outer shell, both with conical bottoms. The electromagnetic heating coil is positioned between the inner and outer shells, with its magnetic field opposite to the magnetic field on the inner wall of the inner shell. The stirring mechanism includes a drive motor, a rotating shaft, and a stirring paddle. On the upper surface of the reaction chamber, a drive motor drives a rotating shaft to rotate the stirring paddle. The stirring paddle includes a hemispherical stirring head, a fan-shaped stirring blade, and a propeller-type stirring component. The hemispherical stirring head is located at the bottom end of the rotating shaft to form a bottom stirring mechanism. The fan-shaped stirring blades are at an angle of ° to each other and are fixedly connected to the rotating shaft at one end to form an upper stirring mechanism. The propeller-type stirring component includes a semi-tubular stirring blade, which is fixed on a fixed disk. The fixed disk is fixed on the rotating shaft and located between the bottom stirring mechanism and the upper stirring mechanism. The semi-tubular stirring blades unfold to form a parallelogram structure. An electromagnetic heating coil and a temperature sensor are respectively connected to a temperature controller.

[0004] Regarding the aforementioned related technologies, the inventors believe that the following defects exist: the device only stirs the concrete water-reducing agent through the stirring blades at the end of the rotating shaft, which results in the concrete water-reducing agent at the upper end of the inner shell not being sufficiently stirred, thus causing the concrete water-reducing agent at the upper end of the inner shell to solidify, thereby reducing the stirring efficiency and thus reducing the work efficiency of the workers. In view of this, a concrete water-reducing agent production device is proposed to solve the above problems. Utility Model Content

[0005] The main purpose of this invention is to provide a concrete water-reducing agent production device, which solves the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a concrete water-reducing agent production device, comprising a box body, wherein an inlet pipe and an outlet pipe are respectively provided at the upper and lower ends of the box body, a lifting mechanism is provided on the box body, a vibration mechanism is provided on the box body, and a support frame for supporting the box body is installed at the lower end of the box body.

[0007] The lifting mechanism includes a stirring shaft vertically installed inside the box, an installation box mounted on the box, a rotatable turntable horizontally installed inside the installation box, a connecting rod rotatably installed off-center on the turntable, an installation plate that can move up and down slidably installed inside the installation box, one end of the connecting rod being rotatably connected to the installation plate, a second motor for driving the stirring shaft to rotate mounted on the installation plate, and a stirring frame mounted on the stirring shaft.

[0008] Furthermore, multiple stirring rods are installed on both the stirring frame and the stirring shaft.

[0009] Furthermore, the mounting box is equipped with a first motor for driving the turntable to rotate, and a through hole is opened in the middle of the box body for the stirring shaft to move up and down.

[0010] Furthermore, the inner sidewall of the mounting box is provided with a sliding groove for the mounting plate to slide, and a scraper is fixed on the outer side of the lower end of the stirring shaft. The scraper is tightly fitted to the bottom of the box and has multiple slots at the bottom.

[0011] Furthermore, the vibration mechanism includes a vibration motor mounted on a support frame, fixed plates mounted on both sides of the top of the vibration motor, a vibration rod welded to the top of the fixed plates, and multiple limiting holes opened at the bottom of the housing, into which the vibration rod is inserted.

[0012] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0013] 1. This concrete water-reducing agent production device is equipped with a lifting mechanism. When it is necessary to stir the water-reducing agent in the tank, the lifting mechanism can drive the stirring shaft, stirring frame and stirring rod to move up and down repeatedly, so as to uniformly stir the water-reducing agent in different positions, thereby reducing the probability of the concrete water-reducing agent solidifying, thereby improving the stirring efficiency and thus improving the work efficiency of the workers.

[0014] 2. This concrete water-reducing agent production device is equipped with a vibration mechanism. When the water-reducing agent in the tank is being stirred, the bottom of the tank is vibrated by the vibration mechanism, which disperses the water-reducing agent and ensures that the ingredients inside the tank are fully mixed, thereby improving work efficiency.

Detailed Implementation

[0017] 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.

[0018] Please see Figure 1 The concrete water-reducing agent production device in this embodiment includes a box body 1. The upper and lower ends of the box body 1 are respectively provided with a feed pipe 3 and a discharge pipe 4. The box body 1 is provided with a lifting mechanism 2 and a vibration mechanism 6. The lower end of the box body 1 is provided with a support frame 5 for supporting the box body 1.

[0019] The lifting mechanism 2 includes a stirring shaft 207 vertically arranged inside the housing 1. A mounting box 201 is installed on the housing 1. A rotatable turntable 203 is arranged horizontally inside the mounting box 201. A connecting rod 204 is rotatably installed on the turntable 203 at an off-center position. A mounting plate 206 that can move up and down is slidably installed inside the mounting box 201. One end of the connecting rod 204 is rotatably connected to the mounting plate 206. A second motor 205 for driving the stirring shaft 207 to rotate is installed on the mounting plate 206. A stirring frame 208 is installed on the stirring shaft 207.

[0020] The device starts the second motor 205, which drives the turntable 203 to rotate. At the same time, the turntable 203 drives the connecting rod 204. The rotation of the turntable 203 causes the mounting plate 206 on the connecting rod 204 to move up and down reciprocally, thereby driving the first motor 202, stirring shaft 207, stirring frame 208 and stirring rod 209 to move up and down, so as to fully stir the water-reducing agent in the tank 1.

[0021] Multiple stirring rods 209 are installed on both the stirring frame 208 and the stirring shaft 207, and the water-reducing agent in the tank 1 is uniformly stirred by the multiple stirring rods 209.

[0022] Meanwhile, the mounting box 201 is equipped with a first motor 202 for driving the turntable 203 to rotate, which facilitates the rotation of the turntable 203 on the first motor 202. A through hole is opened in the middle of the box body 1 for the stirring shaft 207 to move up and down, so that the stirring shaft 207 can move up and down.

[0023] In addition, the inner wall of the mounting box 201 is provided with a sliding groove for the mounting plate 206 to slide, and a scraper 210 is fixed on the outer side of the lower end of the stirring shaft 207. The scraper 210 is tightly fitted with the bottom of the box body 1. Multiple slots 211 are opened at the bottom of the scraper 210 to facilitate better stirring of the bottom of the box body 1.

[0024] Please refer to the figure. In this embodiment, the vibration mechanism 6 includes a vibration motor 601 mounted on the support frame 5. Fixing plates 602 are respectively mounted on both sides of the top of the vibration motor 601. A vibration rod 603 is welded to the top of the fixing plate 602. Multiple limiting holes are opened at the bottom of the box 1, and the vibration rod 603 is inserted into the limiting holes.

[0025] The device starts the vibration motor 601. Since the vibration rod 603 is inserted into the limiting hole, the vibration force generated by the vibration motor 601 is transmitted to the bottom of the box 1 through the vibration rod 603, causing the ingredients to bounce up and down at the bottom of the box 1, thereby making the ingredients inside the box 1 fully mixed and improving work efficiency.

[0026] The working principle of the above embodiments is as follows:

[0027] When workers need to mix the concrete water-reducing agent, they need to move the concrete water-reducing agent through the feed pipe 3 and pour it into the box 1. Then, they start the first motor 202, which drives the mixing shaft 207 to rotate. At the same time, the mixing shaft 207 drives the mixing frame 208 and the mixing rod 209 to rotate, thus mixing the concrete water-reducing agent. Then, they start the second motor 205, which drives the turntable 203 to rotate. At the same time, the turntable 203 drives the connecting rod 204. Through the rotation of the turntable 203, the mounting plate 206 on the connecting rod 204 can move up and down back and forth, thereby driving the first motor 202, the mixing shaft 207, the mixing frame 208 and the mixing rod 209 to move up and down, thus fully mixing the water-reducing agent in the box 1.

[0028] During the mixing process, the vibration motor 601 is started. Since the vibration rod 603 is inserted into the limiting hole, the vibration force generated by the vibration motor 601 is transmitted to the bottom of the box 1 through the vibration rod 603, causing the ingredients to bounce up and down at the bottom of the box 1, thereby making the ingredients inside the box 1 fully mixed and improving work efficiency.
