Description

Technical Field

[0001] The utility model belongs to the technical field of mixing devices, and in particular relates to a powder and liquid mixing device. Background Art

[0002] Steel slag generally contains iron, calcium, magnesium, silicon, aluminum, and other elements. For the environmental protection treatment of steel slag, CO2 mineralization technology can be used, that is, calcium and magnesium in steel slag react with CO2 to form calcium magnesium carbonate, and finally form a new solid product. This technology can transform steel slag into high value-added industrial products, and at the same time, it can also realize the utilization and storage of CO2, which helps to reduce CO2 emissions and alleviate global climate change problems.

[0003] Among them, steel slag and other powders need to be mixed with liquids such as water in a reactor during CO2 mineralization. However, when workers put the powders into the reactor through the feeding pipe, the powders tend to rise or float on the surface of the liquid, and the powders and liquids cannot be mixed quickly, which can easily reduce the mixing efficiency of the powders and liquids.

[0004] Therefore, in view of the above technical problems, it is necessary to provide a powder and liquid mixing device.

[0005] The information disclosed in this background technology section is only intended to increase the understanding of the overall background of the present invention, and should not be regarded as acknowledging or suggesting in any form that the information constitutes the prior art already known to a person skilled in the art. Utility Model Content

[0006] The utility model aims to provide a powder and liquid mixing device, which can solve the problem that powder such as steel slag is easy to rise or float on the surface of liquid when adding.

[0007] In order to achieve the above purpose, the technical solution provided by a specific embodiment of the utility model is as follows:

[0008] A powder and liquid mixing device, comprising: a reaction kettle body and a stirring mechanism;

[0009] A feed pipe is installed on the upper part of the reactor body, the interior of the feed pipe is hollow, one end of the feed pipe is arranged in the reactor body, and the side wall of the feed pipe is connected to a branch pipe;

[0010] The stirring mechanism is installed on the feeding pipe, and the stirring mechanism includes a motor. The motor is installed outside the feeding pipe, and a rotating shaft is connected to an output end of the motor. The rotating shaft is located at one end of the reactor body and is connected to an auger on the side wall.

[0011] In one or more embodiments of the present invention, one end of the feed pipe located in the reactor body is connected to a grinding part, the minimum diameter of the grinding part is larger than the diameter of the rotating shaft, and the grinding part is used to install a grinding plate, which cooperates with the grinding wheel to grind powders such as steel slag entering the reactor body, so that powders such as steel slag can be quickly mixed with the liquid in the reactor body, and are not likely to rise or float on the surface of the liquid.

[0012] In one or more embodiments of the present invention, a grinding plate is installed on the inner wall of the grinding part, which cooperates with the grinding wheel to grind powders such as steel slag entering the reactor body, so that powders such as steel slag can be better mixed with the liquid in the reactor body.

[0013] In one or more embodiments of the utility model, a feed cover is connected to the branch pipe, and the feed cover is connected to the inside of the feed pipe through the branch pipe, so that the staff can add powder materials such as steel slag into the feed pipe.

[0014] In one or more embodiments of the present invention, the side wall of the rotating shaft located inside the reactor body is connected to a bearing, a bearing seat is connected to the outside of the bearing, a reinforcing rod is connected between the bearing seat and the inner wall of the reactor body, and the rotating shaft can be fixed to the inner wall of the reactor body through the bearing, the bearing seat and the reinforcing rod, thereby ensuring the stability of the rotating shaft during rotation.

[0015] In one or more embodiments of the present invention, the bearing is disposed between the grinding portion and the auger, which is less likely to affect the entry of powdered materials such as steel slag into the reactor body.

[0016] In one or more embodiments of the present invention, a grinding wheel is installed on the side wall of the rotating shaft located in the reactor body, and the grinding wheel is arranged in the feed pipe, and the grinding wheel corresponds to the grinding part. When the rotating shaft rotates, the grinding wheel also rotates synchronously. By utilizing the mutual cooperation of the grinding wheel and the grinding plate, the powder such as steel slag entering into the reactor body through the feed pipe can be ground to reduce the volume of the powder such as steel slag, so that the powder such as steel slag can be better mixed with the liquid in the reactor body.

[0017] In one or more embodiments of the present invention, the maximum diameter of the grinding wheel is smaller than the inner diameter of the feed pipe, so that the ground steel slag and other powders can enter the reactor body.

[0018] In one or more embodiments of the present invention, a cavity is provided in the grinding wheel, and a plurality of impact balls are placed in the cavity. When the grinding wheel rotates along with the rotating shaft, the impact balls move irregularly in the cavity. The irregularly moving impact balls will hit the side walls of the cavity, so that the surface of the grinding wheel can vibrate, thereby reducing the probability of powder such as steel slag adhering to the surface of the grinding wheel.

[0019] In one or more embodiments of the present invention, the impact ball is made of rubber, which can not only ensure the effect of the impact ball hitting the side wall of the cavity, but also reduce the sound generated during the impact, and also reduce the impact loss on the side wall, thereby ensuring the service life of the component.

[0028] In order to enable those skilled in the art to better understand the technical solutions in the present invention, the following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0029] like Figures 1 to 4 As shown, a powder and liquid mixing device in one embodiment of the utility model includes a reaction kettle body 1 and a stirring mechanism 2.

[0030] Among them, a feed pipe 101 is installed on the upper part of the reactor body 1. The interior of the feed pipe 101 is hollow. One end of the feed pipe 101 is arranged in the reactor body 1. Powders such as steel slag can enter the reactor body 1 through the feed pipe 101.

[0031] In addition, one end of the feed pipe 101 located in the reactor body 1 is connected to a grinding part 1011, and the minimum diameter of the grinding part 1011 is greater than the diameter of the rotating shaft 202. The grinding part 1011 is used to install a grinding plate 1012, and the grinding plate 1012 cooperates with the grinding wheel 3 to grind the powder such as steel slag entering the reactor body 1, so that the powder such as steel slag can be quickly mixed with the liquid in the reactor body 1, and it is not easy to rise or float on the surface of the liquid.

[0032] Specifically, a grinding plate 1012 is installed on the inner wall of the grinding part 1011, which cooperates with the grinding wheel 3 to grind the powder such as steel slag entering the reactor body 1, so that the powder such as steel slag can be better mixed with the liquid in the reactor body 1.

[0033] In addition, a branch pipe 102 is connected to the side wall of the feed pipe 101, and a feed cover 103 is connected to the branch pipe 102. The feed cover 103 is connected to the inside of the feed pipe 101 through the branch pipe 102. The staff puts powder materials such as steel slag into the feed cover 103, and the powder materials such as steel slag in the feed cover 103 can enter the feed pipe 101 through the branch pipe 102.

[0034] like Figures 1 to 4 As shown, the stirring mechanism 2 is installed on the feed pipe 101. The stirring mechanism 2 is used to press the powder such as steel slag in the feed pipe 101 so that the powder such as steel slag can quickly enter the liquid, and can also grind the powder such as steel slag.

[0035] The stirring mechanism 2 includes a motor 201 , which is installed outside the feed pipe 101 , and a rotating shaft 202 is connected to the output end of the motor 201 , and the motor 201 is used to drive the rotating shaft 202 to rotate.

[0036] In addition, the side wall of the rotating shaft 202 located in the reactor body 1 is connected to a bearing 203, the outer side of the bearing 203 is connected to a bearing seat, and a reinforcing rod 204 is connected between the bearing seat and the inner wall of the reactor body 1. The rotating shaft 202 can be fixed to the inner wall of the reactor body 1 through the bearing 203, the bearing seat and the reinforcing rod 204, thereby ensuring the stability of the rotating shaft 202 during rotation.

[0037] Specifically, the bearing 203 is disposed between the grinding part 1011 and the auger 205 , which is not likely to affect the powder such as steel slag from entering into the reactor body 1 .

[0038] In addition, an auger 205 is connected to the side wall of one end of the rotating shaft 202 located in the reactor body 1. The auger 205 can be used to suppress powders such as steel slag that enter the reactor body 1 through the feed pipe 101, so that powders such as steel slag can enter the liquid and are not easily floated on the surface of the liquid, thereby accelerating the mixing efficiency of powders such as steel slag and liquid.

[0039] like Figures 1 to 4 As shown, the side wall of the rotating shaft 202 located in the reactor body 1 is equipped with a grinding wheel 3, which is arranged in the feed pipe 101, and the grinding wheel 3 corresponds to the grinding part 1011. When the rotating shaft 202 rotates, the grinding wheel 3 also rotates synchronously, and the grinding wheel 3 and the grinding plate 1012 cooperate with each other to grind the powder such as steel slag entering the reactor body 1 through the feed pipe 101, so as to reduce the volume of the powder such as steel slag, so that the powder such as steel slag can be better mixed with the liquid in the reactor body 1.

[0040] Preferably, the maximum diameter of the grinding wheel 3 is smaller than the inner diameter of the feed pipe 101 , so that the ground steel slag and other powders can enter the reactor body 1 .

[0041] Among them, a cavity 301 is provided in the grinding wheel 3, and a plurality of impact balls 302 are placed in the cavity 301. When the grinding wheel 3 rotates following the rotating shaft 202, the impact balls 302 move irregularly in the cavity 301. The irregularly moving impact balls 302 will hit the side wall of the cavity 301, so that the surface of the grinding wheel 3 can vibrate, thereby reducing the probability of powder such as steel slag adhering to the surface of the grinding wheel 3.

[0042] Preferably, the impact ball 302 is made of rubber, which can not only ensure the effect of the impact ball 302 hitting the side wall of the cavity 301, but also reduce the sound generated during the impact and the impact loss on the side wall, thereby ensuring the service life of the component.

[0043] When it is used specifically, when powder materials such as steel slag need to be mixed, liquid is first added into the reactor body 1. The motor 201 is controlled to run, and the motor 201 drives the rotating shaft 202, the auger 205 and the grinding wheel 3 to rotate.

[0044] Powders such as steel slag are put into the feed cover 103, and the powders such as steel slag in the feed cover 103 enter the feed pipe 101 along the branch pipe 102 and fall on the grinding wheel 3 in the feed pipe 101. As the grinding wheel 3 rotates continuously, the powders such as steel slag in the feed pipe 101 are ground by the grinding wheel 3 and enter the reactor body 1 through the gap between the grinding wheel 3 and the grinding plate 1012.

[0045] As the auger 205 rotates continuously, the auger 205 can deliver the powder such as steel slag in the reactor body 1 into the liquid, so that the powder such as steel slag can be quickly mixed with the liquid, thereby improving the mixing efficiency of the powder such as steel slag and the liquid.

[0046] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention.
