Description

Technical Field

[0001] The utility model relates to the technical field of cement preparation, in particular to a cement preparation preheating device. Background Art

[0002] Cement: Powdered hydraulic inorganic cementitious material. After adding water and stirring, it becomes a slurry, which can harden in the air or in water, and can firmly cement materials such as sand and stone together.

[0003] Cement needs to be preheated before preparation for later processing, but the single mixing preheating is often used during the preheating process, which can easily cause uneven heating. In addition, when preheating, the material is easily piled up directly before loading, which can cause the material to pile up and agglomerate, resulting in uneven feeding and too dense feeding, so it needs to be improved. Utility Model Content

[0007] The top surface of the preheater body is equipped with a second drive motor, and a spiral blade is welded on the output shaft of the second drive motor through a second rotating shaft;

[0008] A connecting pipe is embedded and fixed on the bottom end surface of the feed pipe;

[0009] A driving motor 1 is installed on the side end surface of the preheater body through a connecting frame, and a fixing rod is installed on the output shaft of the driving motor 1 through a connecting shaft.

[0010] Preferably, mounting brackets are welded to both ends of the outer surface of the preheater body, and a base is welded to the bottom end surface of the mounting bracket. The preheater body can be installed through the mounting bracket and the base.

[0011] Preferably, a discharge pipe is embedded and fixed on the bottom end surface of the preheater body, and a valve is installed on the discharge pipe through a flange. The discharge pipe is embedded and fixed on the bottom end surface of the preheater body, so that the valve on the discharge pipe can be opened for discharge after the cement material is preheated.

[0012] Preferably, the end of the connecting pipe away from the feed pipe is embedded and fixed in the preheater body, and the preheater body is connected to the feed pipe through the connecting pipe. The pre-processed and dispersed materials in the feed pipe can be discharged through the connecting pipe, so that the materials can be discharged into the preheater body for preparation and processing.

[0013] Preferably, there are two drive motors 2, and the two drive motors 2 are symmetrically distributed with respect to the preheater body. By having two drive motors 2, when the two drive motors 2 are turned on, they can drive the rotating shaft 2 to drive the spiral blade to rotate.

[0014] Preferably, an exhaust pipe is embedded and fixed on the side end surface of the preheater body, and a filter is welded inside the exhaust pipe. The filter is welded inside the exhaust pipe so that the gas generated by preheating can be discharged through the exhaust pipe, and the exhaust gas can be filtered through the filter.

[0017] 2. The utility model sets a preheater body. When personnel preheat cement preparation, after the material is discharged into the preheater body, the personnel can turn on the electric heating wire to heat the preheater body and preheat the internal material. During preheating, the personnel can turn on the second drive motor to drive the stirring rod through the first shaft to stir the material, and can turn on the second drive motor to drive the spiral blade to rotate through the second shaft, so that when the spiral blade rotates, the material can be stirred, moved up and fell again, so that the material can be broken up and heated more evenly, thereby meeting the needs of the later preheating preparation.
