Description

Technical Field

[0001] The utility model relates to the technical field of concrete production, and specifically relates to a water reducer compounding device. Background Technique

[0002] A water reducer is a concrete admixture that can reduce the mixing water consumption under the condition of maintaining the basic unchanged slump of concrete. Most of them belong to anionic surfactants, such as lignosulfonates, naphthalene sulfonate formaldehyde polymers, etc. After being added to the concrete mixture, it has a dispersing effect on cement particles, can improve its workability, reduce the unit water consumption, improve the fluidity of the concrete mixture; or reduce the unit cement consumption and save cement. The water reducer needs to be compounded during use.

[0003] During the use of the water reducer compounding device, the water reducer is directly mixed with other additives. However, the mixing rates of different additives with the water reducer are different, and direct mixing together will cause the problem that some additives are not completely mixed.

[0004] For example, a water reducer compounding device disclosed in Chinese Patent CN218475215U measures the retarder and high-efficiency damping agent required for compounding the water reducer through the dosing cylinder and injects them into the interior of the second compounding tank. Then, the driving motor is started to drive the central rotating shaft to rotate, so that the mixing blades rotate accordingly, and the retarder and high-efficiency damping agent are pre-mixed in the interior of the second compounding tank. After pre-mixing, the drain valve is opened, and the mixture of the retarder and high-efficiency damping agent is discharged into the interior of the first compounding tank. When the mixture of the retarder and high-efficiency damping agent enters the water pipeline, it is flushed onto the water turbine generator under the action of the diversion chute, driving the water turbine generator to rotate for power generation. The electric energy generated by power generation is processed and then delivered to the distribution box for further distribution. After the mixture of the retarder and high-efficiency damping agent enters the first compounding tank, the mother liquor water reducer is added into the interior of the first compounding tank through the water reducer addition port for secondary mixing, so that the pre-mixed sub-material and mother material are fully mixed. Finally, the liquid outlet valve is opened, and the compounded finished water reducer is discharged through the liquid outlet pipe.

[0005] However, in the prior art, when compounding the water reducer, it is necessary to perform pre-mixing treatment on the water reducer so that the water reducer can be better mixed when added to the concrete for mixing and processing.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0027] Please refer toFigures 1-5 , the present utility model provides a technical solution: Embodiment

[0028] A water reducer compounding device includes a support frame 1. A barrel structure is installed on the top of the support frame 1. A stirring structure is installed inside the barrel structure. A mixing structure is installed near the right end of the top of the barrel structure.

[0029] The mixing structure includes a mixing unit and a connecting unit. The mixing unit is arranged inside and at the top of the connecting unit. The mixing unit includes a linkage member 301. A rotating shaft 302 is installed in the middle of the right end of the linkage member 301. A lower wheel 303 is installed at the bottom end of the rotating shaft 302. An upper wheel 304 is installed on the outer surface of the rotating shaft 302 near the top end. The connecting unit includes a mixing barrel 309. A batching port 305 is installed in the middle of the top surface of the mixing barrel 309 near the right end. A liquid inlet pipe 306 is installed at one end near the back of the middle of the top surface of the mixing barrel 309. A connecting pipe 307 is installed in the middle of the bottom surface of the mixing barrel 309. A flow monitoring valve 308 is installed in the middle of the connecting pipe 307.

[0030] The outer surface of the rotating shaft 302 near the top end is connected to the inside of the circular hole opened in the middle of the top surface of the mixing barrel 309 through a bearing. The upper wheel 304 and the lower wheel 303 are installed in a mirror image.

[0031] Through the setting of the mixing structure, the linkage member 301 is used to drive the rotating shaft 302 to rotate. When the rotating shaft 302 rotates, it drives the lower wheel 303 and the upper wheel 304 to rotate, so as to pre-mix the water reducer. When the water reducer is mixed, liquid counterflow is utilized, so that the mixing effect of the water reducer is better.

[0032] When pre-mixing the water reducer, when the asynchronous motor 201 drives the transmission member 202 and the stirring shaft 203 to transmit power, the stirring shaft 203 is used to drive the linkage member 301 to transmit power. The stirring shaft 203 drives the driving wheel to rotate. Through the belt transmission connection of the driving wheel, the belt and the driven wheel, the driven wheel is used to drive the rotating shaft 302 to rotate. When the rotating shaft 302 rotates, it drives the lower wheel 303 and the upper wheel 304 to rotate. The water reducer is placed into the mixing barrel 309 through the batching port 305, and the pre-mixed liquid is placed into the mixing barrel 309 through the liquid inlet pipe 306. Thus, due to the mirror image setting of the lower wheel 303 and the upper wheel 304, the mixed liquid is subjected to liquid flow counterflow. Therefore, when mixing the water reducer, the water reducer can be mixed more thoroughly and is more easily mixed with concrete. When the water reducer is transported through the connecting pipe 307, by installing the flow monitoring valve 308, the dosage of the added water reducer can be controlled, so as to better produce concrete. Embodiment

[0033] Based on the first embodiment, the barrel structure includes a mixing barrel 101. In the middle of the top surface of the mixing barrel 101, a feeding pipe 102 is installed near the left end. At the top of the feeding pipe 102, a feeding hopper 103 is installed. In the middle of the bottom surface of the mixing barrel 101, a discharging pipe 104 is installed. The middle part of the outer surface of the mixing barrel 101 is fixedly connected to the middle part of the top surface of the support frame 1. The inner wall of the installation hole opened near the right end in the middle of the top surface of the mixing barrel 101 is fixedly connected to the bottom end of the outer surface of the connecting pipe 307.

[0034] The mixing structure includes an asynchronous motor 201. The output end of the asynchronous motor 201 is connected to a transmission member 202. Inside the transmission member 202, a mixing shaft 203 is connected. On the outer surface of the mixing shaft 203, an auger 204 is installed. Near the top end of the outer surface of the mixing shaft 203, a mixing rod 205 is installed. At one end of the mixing rod 205 away from the mixing shaft 203, a scraper 206 is installed. At the bottom end of the mixing shaft 203, a turntable 207 is installed. On the outer surface of the turntable 207, an arc-shaped plate 208 is fixedly installed. The bottom of the asynchronous motor 201 is detachably installed and connected to the top surface of the mixing barrel 101. The outer surface of the scraper 206 is slidably connected to the inner wall of the mixing barrel 101. The bottom surface of the arc-shaped plate 208 is slidably connected to the bottom surface of the inner wall of the mixing barrel 101. The top end of the mixing shaft 203 is connected to the inside of the left end of the linkage member 301.

[0035] Through the setting of the mixing structure, the asynchronous motor 201 is used to drive the transmission member 202 and the mixing shaft 203 to rotate, so that the mixing of concrete and water reducing agent is more thorough by using the auger 204. Moreover, the inner wall of the mixing barrel 101 can be cleaned by using the scraper 206. And during the discharging process, due to the arc angle of the arc-shaped plate 208, the stirred concrete can be better discharged.

[0036] When mixing concrete, start the asynchronous motor 201 to drive the transmission member 202 for transmission. The output end of the asynchronous motor 201 drives the worm to rotate. By using the meshing connection between the worm and the worm wheel, the asynchronous motor 201 drives the worm wheel and the mixing shaft 203 to rotate. Thus, the mixing shaft 203 drives the auger 204 to rotate. When the auger 204 rotates, it can turn the concrete at the bottom upward. Thus, when the concrete is mixed, it can be better mixed with the water reducing agent. At the same time, when the mixing shaft 203 rotates, it drives the mixing rod 205 and the scraper 206 to rotate. The inner wall of the mixing barrel 101 is scraped by using the scraper 206 to prevent the concrete from adhering to the inner wall of the mixing barrel 101. By driving the rotation of the turntable 207 and the arc-shaped plate 208 by the mixing shaft 203, the concrete at the bottom of the mixing barrel 101 can be scraped. At the same time, due to the arc angle of the arc-shaped plate 208, it effectively assists the discharging of the concrete. Thus, it is convenient to discharge through the discharging pipe 104.
