Description

Hot air supply device for dry sand feeder

Technical Field

The utility model relates to a dry sand material technical field specifically indicates a hot-air supply arrangement for dry sand glassware.

Background

The machine-made sand or natural sand raw material in the dry-mixed mortar product is dried before use. The rotary kilns adopted by the dry-mixed mortar sand in the current stage of China mostly adopt coal-fired heat energy air supply or gas heat energy air supply, about 10kg of coal is needed for drying machine-made sand with the water content of 5 percent of 1 ton, and about 5m3 is needed for converting the machine-made sand into gas. Due to the reasons of product quality requirements, environmental protection policies and the like, most of sand products for dry-mixed mortar need to be washed and processed and can be utilized after dehydration and drying, and the heat energy utilization rate in the existing sand drying device is not high, so that the actual requirements can not be met.

SUMMERY OF THE UTILITY MODEL

In order to solve the technical problem, the utility model provides a technical scheme does: the utility model provides a hot-air supply arrangement for dry sand glassware, includes rotary kiln formula desicator, to the heat dissipation wind storehouse of cold wind heating, communicates heat dissipation wind storehouse and rotary kiln formula desicator give the trachea, be provided with the draught fan that provides power in giving the trachea, still include the cold-blast pipe, cold-blast pipe one end is connected with the supply-air outlet, and the other end inserts heat dissipation wind storehouse, be equipped with the radiator in the intercommunication heat dissipation wind storehouse, the wet return of radiator sets up in the cold-blast pipe.

As an improvement, the rotary kiln type dryer comprises a rotary body, a feeding port and a discharging port, wherein the feeding port and the discharging port are arranged on the rotary body, and a hot air port is arranged in the rotary body and is used for being connected with an air supply pipe.

As an improvement, the feed inlet is arranged at the top of one end, close to the induced draft fan, of the rotary kiln type dryer, and the discharge outlet is arranged at the bottom of the other end of the rotary kiln type dryer.

After the structure more than adopting, the utility model has the advantages of as follows: the utility model discloses simple structure, it is convenient to set up, prolongs the cold air pipe through the return water behind the radiator and lays, can utilize cold wind and return water difference in temperature to preheat cold air, improves heat utilization rate.
