Technical Field

[0001] This utility model relates to the technical field of mixing devices, specifically a raw material water mixing device for the production of permeable bricks. Background Technology

[0002] Breathable bricks are a new product with a long lifespan and energy saving. They have good thermal stability, erosion resistance, corrosion resistance and impermeability. They are characterized by high blow-through rate, safe and reliable operation and long service life. The manufacturing process of breathable bricks includes fine powder co-grinding, mixing, vibration casting molding, curing, baking, high temperature firing and steel shell sealing. During the mixing process, the powdered raw materials need to be mixed with water to form a mud-like consistency.

[0003] However, existing mixing devices typically inject water directly into the cylinder when adding water, requiring a long stirring time to ensure that the powder and water are mixed evenly, thus increasing the stirring time. Utility Model Content

Each stirring rod is provided with a water outlet, and a one-way nozzle is provided inside the water outlet. One end face of the one-way nozzle is circular and the other end face is rectangular. A rectangular nozzle is provided on the rectangular end face of the one-way nozzle. The one-way nozzle is made of rubber. In its natural state, the rectangular nozzle is in a closed state. When water needs to be sprayed, the rectangular nozzle can be deformed by water pressure, so that water is sprayed out through the rectangular nozzle. A feed pipe is connected to the top of the cylinder, and a discharge port is provided at the bottom of the cylinder.

[0006] Preferably, both the stirring rod and the rotating shaft are tubular structures and water can flow inside them. The upper end of the rotating shaft extends outside the cylinder and is connected to a water supply pipe through a rotary joint.

[0007] Preferably, a bevel gear one is fixedly installed on the rotating shaft, a reducer is fixedly installed above the cylinder, a bevel gear two that meshes with the bevel gear one is installed at the power output end of the reducer, and a motor is connected to the power input end of the reducer.

[0009] Preferably, a scraper is fixedly provided at the end of the stirring rod, and the scraper is in contact with the inner wall of the cylinder.

[0010] Beneficial effects

[0011] This utility model provides a raw material water mixing device for the production of breathable bricks, which has the following beneficial effects: by setting a water outlet on the rotatable stirring rod, water can be evenly introduced into the powder in the cylinder, improving the mixing effect of powder and water and reducing the stirring time.

[0016] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0017] Please see Figure 1-3 This utility model provides a technical solution: a raw material water mixing device for the production of breathable bricks, including a cylinder 1, a rotating shaft 2 rotatably arranged inside the cylinder 1, and multiple pairs of stirring rods 3 fixedly arranged along the height direction on the rotating shaft 2. When the rotating shaft 2 rotates, the stirring rods 3 stir the material in the cylinder 1. Each stirring rod 3 is provided with a water outlet 4, and a one-way nozzle 15 is provided in the water outlet 4. One end face of the one-way nozzle 15 is circular and the other end face is rectangular. A rectangular nozzle 16 is opened on the rectangular end face of the one-way nozzle 15. The one-way nozzle 15 is made of rubber. In the natural state, the rectangular nozzle 16 is in a closed state. When water needs to be sprayed, the rectangular nozzle 16 can be deformed by water pressure, so that water is sprayed out through the rectangular nozzle 16. The water is evenly injected into the powder by moving the stirring rods 3. A feed pipe 6 for the powder to enter is connected to the top of the cylinder 1, and a discharge port 7 for discharging mud is provided at the bottom of the cylinder 1.

[0018] As an embodiment of this utility model, both the stirring rod 3 and the rotating shaft 2 are tubular structures and water can flow inside them. The upper end of the rotating shaft 2 extends to the outside of the cylinder 1 and is connected to a water supply pipe 9 through a rotary joint 8.

[0019] As an embodiment of this utility model, a bevel gear 10 is fixedly installed on the rotating shaft 2, and a reducer 11 is fixedly installed above the cylinder 1. A bevel gear 12 that meshes with the bevel gear 10 is installed at the power output end of the reducer 11, and a motor 13 is connected to the power input end of the reducer 11. The speed can be reduced while the torque can be increased through the reducer 11.

[0020] As an embodiment of this utility model, a groove 14 is provided in the water outlet 4, and a protrusion 17 is fixedly provided on the outer surface of the circular end of the one-way nozzle 15, and the protrusion 17 can be fitted into the groove 14.

[0021] As an embodiment of this utility model, a scraper 5 is fixedly provided at the end of the stirring rod 3. The scraper 5 is in contact with the inner wall of the cylinder 1. The material adhering to the inner wall of the cylinder 1 is scraped off by the scraper to improve the stirring effect.

[0022] The working principle and usage process of this utility model are as follows: During use, the powder enters the cylinder 1 through the feed pipe 6, the water supply pipe 9 is connected to the water source, the motor 13 is started to rotate the shaft 2 and the stirring rod 3, and the water valve of the water supply pipe 9 is opened when the stirring rod 3 is rotating, so that water can be drained into the powder through the rectangular nozzle 16, so that water can be evenly injected into the powder in the cylinder 1, improving the mixing effect of powder and water. When the water injection stops, the rectangular nozzle 16 can automatically close to prevent mud from entering the stirring rod 3. After the mud is mixed, it is discharged through the discharge port 7. When it is necessary to clean the inner wall of the cylinder 1, the water valve of the water supply pipe 9 is opened and the motor 13 is started to rotate the shaft 2. By changing the speed of the motor 13, the rotation speed of the shaft 2 can be increased. When the shaft 2 rotates at high speed, the centrifugal force can throw the mud attached to the stirring rod 3 onto the inner wall of the cylinder 1, and water can be sprayed onto the inner wall of the cylinder 1 through the rectangular nozzle 16 to achieve the rinsing of the inner wall of the cylinder 1.

[0023] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
