Description

Cement clinker transfer device for laboratory

Technical Field

The utility model belongs to the field of cement clinker calcination, and particularly relates to a cement clinker transfer device for a laboratory, which can be particularly applied to transfer of cement clinker before quenching in the laboratory.

Background

In the existing cement production process, the firing of the cement clinker needs three steps, namely raw material decomposition, clinker calcination and clinker quenching, and in order to optimize the cement clinker production process or cement production formula, a small-scale cement clinker calcination experiment needs to be carried out in a laboratory. The rapid cooling process of the cement clinker in laboratory scale is to take the cement clinker out of a high-temperature electric furnace at 1450 ℃ and then rapidly transfer the cement clinker to the position under an electric fan for rapid cooling, and most of the current laboratory transfer methods use crucible tongs to directly clamp a crucible container filled with the cement clinker. Thus, there is a need for a cement clinker transfer apparatus to assist in rapid cooling of cement clinker.

The Chinese patent of utility model (self-made device for quickly cooling the calcined clinker in the laboratory) (patent number CN 212975184U) discloses a self-made device for quickly cooling the calcined clinker in the laboratory, which adopts a water-cooling structure and does not relate to the transferring process of the cement clinker; the Chinese utility model (patent No. CN 216917785U) discloses a discharging device for laboratory cement clinker, but the device has a fixed structure and is complex to operate. Other new chinese patents such as "cement clinker cooling device" (patent number CN 214148559U) are large-scale cement clinker coolers for industrial grade applications, which cannot meet the laboratory scale applications.

In view of the above, there is still a need for a cement clinker transferring device suitable for laboratories, which can meet the requirements of laboratory use, can be matched with a common high-temperature electric furnace to take and place sample saggers, and can avoid fire or personal safety accidents caused by collision and splash of samples as much as possible in the use process.
