Furthermore, the wear-resisting brick is a chrome corundum wear-resisting brick, the wear resistance of the blanking hopper is improved, the heat insulation cotton is arranged on the outer side of the wear-resisting brick, the heat insulation performance is improved, the heat loss is reduced, and the clay refractory slurry is used as a binder for the wear-resisting brick and the prefabricated brick during brick laying.

Further, a vertical pre-heater, vertical pre-heater bottom is provided with the unloading funnel, the unloading funnel be above-mentioned vertical pre-heater masonry type unloading funnel.

Further, the vertical preheater comprises a storage bin, a material pushing platform and a discharging hopper.

The utility model has the advantages that:

1. the utility model discloses a vertical pre-heater masonry type blanking funnel and vertical pre-heater thereof, adopts the precast brick masonry to replace the traditional formwork pouring, effectively solves the problems of formwork difficulty and poor pouring quality;

2. the utility model discloses a vertical pre-heater masonry type blanking funnel and vertical pre-heater thereof, which adopts the prefabricated bricks which are designed in advance to masonry, can control the quality of the prefabricated bricks, ensure the tightness of the blanking funnel after masonry, and improve the quality of the blanking funnel;

3. the utility model discloses a vertical pre-heater masonry formula unloading funnel and vertical pre-heater thereof adopts prefabricated brick masonry mode than formwork pouring swift, convenient, and the engineering time is short, and prefabricated brick toasts through high temperature moreover, has avoided in the field usage owing to toast the phenomenon that the out-of-position production bursts.
