It is entered in deep fat helix tube in the logical oily radially-arranged multiple fuel feed holes of rotary shaft, passes through logical oily rotary shaft band in the course of work
Wet sand is heated in dynamic deep fat helix tube rotation, and last deep fat discharges tank body by flowline.
The heating tank work of the present invention is divided into two kinds of operating modes：
Operating mode one：Dry operating mode drives heating tank transmission belt so as to drive the logical oil of change gear box control by motor
Rotary shaft and deep fat helix tube rotate, and wet sand enters heating chamber by feed pipe in the course of work, are made by the stirring of deep fat helix tube wet
Sand comes into full contact with heating cavity wall and deep fat helix tube, achievees the purpose that fully to heat and stir, the dry sand finally machined
Tank body is discharged via discharge port,
Operating mode two：Clear product operating mode, this operating mode are only carried out in deep fat helix tube zero load, and blow cylinder is run at this time, is passed through
Protection board on blow cylinder shaking heating cavity outer wall, removes the caking wet sand for being attached to heating cavity wall, finally by deep fat spiral shell
Coil rotation drives caking wet sand to discharge tank body by discharge port, completes clear product operating mode.
The stirred tank workflow of the present invention：
When equipment preheats, hot fluid is passed through in heat exchanger tube, stirred tank is heated.
During equipment elimination run, positive motor drives positive motor shaft and rotates forward blade rotation, and reverse motor passes through stirred tank
Transmission belt drives reverse motor axis and reversion blade rotation.
During charging, conveyer belt drives wet sand to enter in stirred tank, is heated by stirred tank wall, and driven by forward and reverse blade
Rotation makes wet sand be sufficiently stirred and pre-add heated drying.
During discharging, it is processed after sand entered by being located at the discharge port of stirred tank bottom positioned at canyon and teeter chamber
Between blow tank in, finally drive discharging by being located at the indoor discharging machine of equipment, complete whole process.
During equipment automatically cleaning, conveyer belt stops charging, and discharging machine is kept it turned on, and starts blow cylinder at this time until stirring
It mixes wet sand in kettle to be entered in blow tank by discharge port completely, until driving discharging completely by discharging machine.
The heat exchanging part of the present invention includes three groups of heat-exchange systems：
Thermal oil system：It is made of heat conducting oil boiler and heating tank, deep fat is by heat conduction oil boiler stove heat and is passed into heating tank
It exchanges heat in deep fat helix tube, then turns again in heat conducting oil boiler, form deep fat heat exchange cycle.
