Description

Technical Field

[0001] The utility model relates to the technical field of refractory brick production, in particular to a raw material mixing device for refractory brick production. Background Technique

[0002] Refractory materials are generally divided into two types, namely unshaped refractory materials and shaped refractory materials. Unshaped refractory materials, also called castables, are a mixture of powdery particles composed of various aggregates or fillers and one or more binders. When in use, they must be mixed and stirred evenly with one or more liquids and have strong fluidity; shaped refractory materials generally refer to refractory bricks, which have standard and regular shapes and can also be temporarily processed during cutting according to needs.

[0003] In the production process of refractory bricks, a mixing device is needed to mix and stir the raw materials. For example, the Chinese utility model patent with the publication number CN217367980U discloses a raw material mixing device for refractory brick production, including a machine case. The top of the machine case is bolted with a box body. A stirring mechanism is arranged in the inner cavity of the machine case. The top of the right side of the machine case is communicated with a feed pipe, and the top of the feed pipe is communicated with a funnel. Both sides of the front of the box body are hinged with box doors through hinges. The bottom of the machine case is communicated with a discharge pipe, and a valve is arranged on the right side of the discharge pipe. The stirring mechanism includes a motor, a first rotating shaft, a first stirring blade, a second stirring blade, a driving wheel, a driven wheel, a second rotating shaft and a third stirring blade. The center of the top of the inner cavity of the box body is bolted with a motor. The output shaft of the motor is bolted with a first rotating shaft. The center of the top of the machine case is rotationally connected with the surface of the first rotating shaft through a rotating sleeve. The top of both sides of the first rotating shaft is sequentially bolted with first stirring blades from top to bottom. The bottom of both sides of the first rotating shaft is sequentially bolted with second stirring blades from top to bottom. The length of the second stirring blades decreases from top to bottom. The surface of the first rotating shaft is sequentially key-connected with driving wheels from top to bottom. The surface of the driving wheel is connected with a driven wheel through a belt drive. The inner cavity of the driven wheel is key-connected with a second rotating shaft. The top of the second rotating shaft is rotationally connected with the top of the inner cavity of the box body through a bearing. Both sides of the top of the machine case are rotationally connected with the surface of the second rotating shaft through rotating sleeves. The top of both sides of the second rotating shaft is sequentially bolted with third stirring blades from top to bottom. The beneficial effect of this utility model is that through the cooperation of the motor, the first rotating shaft, the first stirring blade, the second stirring blade, the driving wheel, the driven wheel, the second rotating shaft and the third stirring blade, the stirring effect on the raw materials is improved, the raw materials are mixed evenly, and the qualified rate of refractory bricks is improved. Through the pointed cones on the second stirring blades, the raw materials can be broken, preventing the raw materials from clogging at the bottom of the machine case. However, there are also certain defects: the raw materials for refractory brick production include a variety of granular materials and fine powder materials. After pouring the granular materials and fine powder materials into the machine case together, due to the light specific gravity and poor fluidity of the fine powder materials, they are extremely likely to float to the upper end of the machine case, resulting in the failure of the raw materials to be mixed smoothly.

One side of the top of the mixing tank 1 is provided with a feed inlet 2, and the other side of the top of the mixing tank 1 is provided with a humidifying component. The humidifying component includes a humidifying tank 4. One side of the humidifying tank 4 is connected with a feeding pipe 5. The feeding pipe 5 includes a first horizontal pipe 51, a first elbow 52, a vertical pipe 53, a second elbow 54 and a second horizontal pipe 55 arranged in sequence. Adjacent pipes are connected by flanges. Among them, a powder inlet 6 is provided on the first horizontal pipe 51, and a wind hood 7 is provided at the front end of the first horizontal pipe 51. A filter screen is arranged in the wind hood 7, which is beneficial to filtering the inhaled air to avoid impurities in the air from mixing into the fine powder and affecting the production of refractory bricks. Anti-impact plates 56 are arranged in both the first elbow 52 and the second elbow 54. The anti-impact plates 56 are connected with the inner walls of the first elbow 52 and the second elbow 54 through springs. By arranging the anti-impact plates 56, it is beneficial to avoid the impact and friction of the material on the elbow, extend the service life of the elbow, and at the same time, the anti-impact plates 56 can also break the lumps in the fine powder. A fan 8 is arranged on the other side of the humidifying tank 4. The fan 8 generates negative pressure to suck the fine powder into the humidifying tank 4 through the powder inlet 6 for humidifying treatment to avoid floating when mixed with other materials. A water pump 9 is arranged on the top of the humidifying tank 4. The water inlet end of the water pump 9 is connected with a water inlet pipe 10, and the water outlet end is connected with a water outlet pipe 11. The lower end of the water outlet pipe 11 penetrates the top wall of the humidifying tank 4 and is connected with a water distributor 12. A discharge pipe 13 is arranged at the bottom of the humidifying tank 4. The discharge pipe 13 is communicated with the mixing tank 1. During humidification, the fine powder enters the humidifying tank 4 along with the air flow under the action of the fan 8. The water pump 9 pumps the external water source into the humidifying tank 4 and sprays it through the water distributor 12. After the fine powder is wetted, it enters the mixing tank 1 through the discharge pipe 13. A discharge port 3 and legs 18 are arranged at the bottom of the mixing tank 1.

[0023] A stirring component is arranged in the mixing tank 1. The stirring component includes a motor 14. The motor 14 is fixedly arranged at the center of the top of the mixing tank 1. The output shaft of the motor 14 penetrates the top wall of the mixing tank 1 downward and is connected with an eccentric wheel 15. The bottom of the eccentric wheel 15 is connected with a stirring shaft 16. Stirring blades 17 are arranged on the stirring shaft 16. By arranging the stirring component, it can make the mixing of various raw materials more uniform.

[0024] Working principle: When in use, granular materials enter the mixing box 1 through the feeding port 2. Fine powder materials enter the humidifying box 4 through the conveying pipe 5 under the action of the fan 8. When passing through the conveying pipe 5, the fine powder materials impact the anti-impact plate 56 at the elbow. On the one hand, it can avoid damaging the inner wall of the elbow, and on the other hand, it can also break up the small lumps in the fine powder materials to make the mixing more uniform. When the fine powder materials enter the humidifying box 4, the water pump 9 operates to pump the external water source into the humidifying box 4, and it is evenly sprayed out through the water distributor 12 to wet the fine powder materials. The wetted fine powder materials enter the mixing box 1 through the discharge pipe 13 and are fully mixed with the granular materials under the action of the stirring blades 17, and then are discharged through the discharge port 3.
