Description

Technical Field

[0001] This utility model relates to the field of granulation equipment technology, specifically to a wet granulation machine. Background Technology

[0002] As one of the key pieces of equipment in a carbon black production line, the wet granulation machine is used to transport the collected carbon black dust to the machine, where a mixture of water and binder is sprayed in. The mixture is then mixed with the dust under the centrifugal force of the high-speed rotation of the stirring shaft. This causes the carbon black to rub against the stirring head and the cylinder wall to form uniform and dense particles. After being dried by the dryer, the particles are easy to collect, thereby reducing packaging volume and dust pollution.

[0003] Among the relevant technologies, a search revealed a Chinese invention patent titled "A High-Efficiency ZL-4 C Type Wet Granulator" with publication number CN110368871A. This patent adds two sets of spirally arranged stirring teeth to the granulation zone of the double-spiral stirring shaft, making the granulation zone a four-spiral structure. This achieves the purpose of extending the residence time of the material in the granulation zone and improving the particle strength, hardness, and surface smoothness.

[0004] However, its stirring teeth are fixed and can only produce particles of a fixed size, which limits the size of the particles produced and makes it inconvenient for operators to use. To solve the above problems, a wet granulation machine is proposed. Utility Model Content

[0005] In view of this, the present invention provides a wet granulation machine. The present invention uses the threaded connection between the toothed head and the toothed rod to adjust the distance between the external screw and the internal thread by twisting the toothed head, thereby adjusting the distance between the toothed head and the toothed rod, and thus adjusting the distance between the toothed head and the inner wall of the cylinder, thereby facilitating the production of different granules and making it convenient for operators to use.

[0006] To solve the above-mentioned technical problems, this utility model provides a wet granulation machine, including a stirring shaft arranged inside a cylinder, a feeding spiral blade arranged on the stirring shaft, a plurality of spiral stirring teeth arranged at the rear of the feeding spiral blade, each spiral stirring tooth including a fixing ring connected to the surface of the stirring shaft, a toothed rod arranged on the fixing ring, a toothed head arranged at the top of the toothed rod, the toothed rod having a hollow design inside, the toothed head being connected to the toothed rod by a thread, and a positioning ring arranged at the upper end of the toothed rod.

[0007] The tooth head has an external screw at the bottom, which is used to connect with the internal thread, thus enabling a detachable connection between the tooth head and the tooth bar. The tooth bar has an internal thread at the top, which is used to receive the external screw, thus connecting the tooth head and the tooth bar. The internal thread and the external screw thread are engaged.

[0008] The fixed ring is provided with screw holes for installing positioning bolts, thereby connecting the fixed ring to the stirring shaft. This allows for the reduction or addition of toothed rods and toothed heads as needed. The screw holes and toothed rods are spaced apart. The fixed ring is connected to the stirring shaft by bolts.

[0009] The tooth head is cylindrical and welded to the external screw at the bottom. The top of the tooth head has a flange, which is used to insert into the slot to strengthen the connection between the tooth head and the tooth rod and prevent it from falling off. The positioning ring has a slot for flange sealing and matching, which is used to receive the flange on the tooth head.

[0010] Multiple support frames are provided on the feed spiral blades. The support frames are used to fix the pulleys and support them. The support frames are also used to connect the pulleys to the feed spiral blades. The support frames are hollow U-shaped. Each support frame has a pulley rotatably installed inside. The pulleys are used to support and position the stirring shaft when it needs to be pulled out of the cylinder for maintenance.

[0011] Multiple nozzle devices are installed on the side adjacent to the feed port of the cylinder. The nozzle devices are used to spray liquid onto the material inside the cylinder. Each nozzle device is installed on the cylinder wall.

[0012] Each nozzle assembly includes a spray chamber for mounting the nozzle and connector, and also for supporting the connector and nozzle. The spray chamber is embedded in the cylinder wall, with one end inside the cylinder and the other end outside. A nozzle is detachably mounted on the end of the spray chamber closest to the center of the cylinder, and the nozzle is used to diffuse the liquid towards the center of the cylinder. The center of the spray chamber is filled with filter material to prevent impurities in the supplied liquid from clogging the nozzle.
