[0001] The invention relates to the technical field of granulation equipment, in particular to a ceramic dry granulation unit. Background Art

[0002] Ceramic dry granulation is a method of preparing ceramic powder into particles of a certain shape and size. It is an important step in the ceramic preparation process. Granular materials are easy to load and distribute into molds, reduce molding defects, and ensure product dimensional accuracy and appearance quality. At the same time, by precisely controlling process parameters (such as particle size and shape), the formula ratio can be optimized to meet different application requirements.

[0003] At present, in the prior art, when ceramic powder is mixed with the spraying liquid, a portion of the ceramic powder will fall onto the inner wall of the conical shell of the equipment. In order to clean it, vibration is usually used. However, with this method, when vibrating, the wet ceramic powder is discharged extremely irregularly and in a collapsed state, which is not conducive to subsequent operations. In view of this, the present application proposes a ceramic dry granulation unit to solve this problem. Summary of the Invention

However, this method causes the wet ceramic powder to be discharged extremely irregularly, and the powder will be discharged in a collapsed state, which is not conducive to subsequent operations.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solutions: a ceramic dry granulation unit, comprising a granulator body and a first transverse plate fixedly connected to the middle outer wall thereof, a pair of first legs fixedly connected to the interior of both sides of the first transverse plate, a second transverse plate fixedly connected to the top end of the right first leg, a cleaning mechanism and a conveying mechanism respectively installed at the bottom and top end of the granulator body;

[0006] The cleaning mechanism includes a flexible connection sleeve fixed to the outer wall of the bottom end of the granulator body, a base is fixed to the bottom end of the flexible connection sleeve, a pair of legs are fixed to the bottom end of the base, and a first fan is fixed to the side wall of the base, the air outlet pipe of the first fan is connected to the cavity inside the bottom end of the granulator body, and a rotating component is installed on the inner wall of the bottom end of the base.

[0009] Preferably, the spray assembly includes a plurality of water pipes fixedly connected to the inside of the top of the granulator body, and the water pipes are equidistantly distributed in a circular shape with the middle of the top of the granulator body as a circle, and the bottom ends of the water pipes are connected to the atomizing spray head.

[0010] Preferably, an exhaust pipe is fixedly connected to the top of the granulator body, and the bottom end of the exhaust pipe is communicated with the annular exhaust groove on the inner wall of the top end of the granulator body.

[0011] Preferably, a discharge hopper is fixedly connected to the side wall opening of the base.

[0012] Beneficial effects

[0013] The present invention provides a ceramic dry granulation unit, which has the following beneficial effects:

[0014] The ceramic powder is discharged into the feed hopper through the external feeding equipment, and then the second motor drives the screw feeder to rotate, and the ceramic powder is transported to the right by the screw feeder, and then the ceramic powder enters the distributor through the discharge barrel. At the same time, the second fan blows air into the discharge barrel. Under the action of gas flow, the ceramic powder can be sprayed out from the distributor more quickly and evenly. At this time, the external water supply device injects water into several water pipes, and the water is sprayed through the atomizing spray head to wet the ceramic powder sprayed from the distributor. Part of the wet ceramic powder will directly fall onto the turntable through the bottom opening of the granulator body, and part will fall onto the inner wall of the bottom end of the granulator body. At this time, the first fan blows air to the granulator body. Air is blown into the internal cavity at the bottom of the granulator body, and the air flow is discharged through the air holes on the inner wall of the bottom end of the granulator body, thereby blowing up the wet ceramic powder that has fallen on the inner wall of the bottom end of the granulator body, so that it falls onto the turntable by its own weight. At the same time, the blown air flow will also make the unhumidified ceramic dust float upward and be in a suspended state, and come into contact with the atomized spray liquid for the second time to be wetted. In this way, the wet ceramic powder will be discharged more regularly and will not be in a collapsed state. Finally, the first motor drives the first bevel gear to rotate through the second bevel gear, and the first bevel gear drives the turntable to rotate. The centrifugal force generated by the turntable can throw the wet ceramic powder out from the discharge hopper for the next granulation process, so the actual use effect is better.
