Description

Evaporative pattern drying room

Technical field

The utility model relates to a kind of evaporative pattern drying room.

Background technology

In evaporative pattern manufacturing process, will carry out drying after the first-class coating of mould, dry run is exactly put in drying room by the mould of first-class coating to carry out drying or natural drying.Drying room drying is adopt electrical heating, heat collection and traditional coal heating substantially, and is disposable drying, wastes energy.

Summary of the invention

The purpose of this utility model is just to provide a kind of evaporative pattern drying room, to solve existing disposable drying, the problem that waste heat is wasted; Adopt secondary drying mode, make full use of thermal source, make drying effect better.

Technical scheme:

Evaporative pattern drying room, comprise the drying room of sealing, burner, air exhauster, heat supply pipeline, moisture exhausting port and Automatic Temperature Control, it is characterized in that drying room is made up of dry drying room and wet drying room, outside wet drying room, there is burner to be communicated with heat supply pipeline entrance, heat supply pipeline is m shape, inflection shape is arranged in wet drying room repeatedly, and the outlet of heat supply pipeline is provided with air exhauster, and the outlet of air exhauster is communicated with in dry drying room; Wet drying room has front moisture exhausting port, and dry drying room has tail moisture exhausting port.

Import and the burner of heat supply pipeline are tightly connected, and outlet and air exhauster air inlet are tightly connected.One end and the air exhauster air outlet of outlet are tightly connected, and the other end to be communicated with in dry drying room and to be tightly connected with dry drying room wall.Described tail moisture exhausting port and front moisture exhausting port are separately positioned on one jiao of dry drying room and wet drying room, are separately installed with front exhaust blower, tail exhaust blower.

Smoke exhaust pipe is positioned at burner center of top, is communicated with the burner hearth of burner, is tightly connected with the furnace wall of burner.

Add heat-insulation layer in the middle of described drying room two-layered steel plates to be welded, support and the heat supply pipeline of putting evaporative pattern all adopt metal steel pipe.Burner produce heat energy under the effect of air exhauster, heat energy after the heat supply pipeline arranged in wet drying room by directly entering dry drying room with the outlet that air exhauster air outlet is connected with dry drying room.

Smoke exhaust pipe is positioned at burner center of top, is tightly connected, is communicated with burner hearth with burner.Drying room front is provided with the drying room door can opened with hermetically closing.

Namely a kind of evaporative pattern drying room has been made according to technique scheme, during use, the heat energy that burner produces is under the effect of air exhauster, the heat supply pipeline of the wet drying room sole arrangement of warp is to heat supply in wet drying room, thus preliminarily dried is carried out to the evaporative pattern be placed in wet drying room on support, the exhaust blower that the moisture produced in dry run is installed through moisture exhausting port is discharged.Heat energy directly enters in dry drying room by exporting with air exhauster the heating tube be connected with dry drying room after wet drying room heat supply pipeline, by again dry for the evaporative pattern by being placed on support after wet drying room preliminarily dried, the exhaust blower that the moisture produced in dry run is installed through moisture exhausting port is discharged.Automatic Temperature Control can cut off air exhauster power supply automatically when temperature is too high, and air exhauster quits work, and temperature decreases.The coal smoke that burner produces is discharged by smoke exhaust pipe.Evaporative pattern toasts in drying room through secondary, gradation hydrofuge, and temperature is more convenient for controlling, and ensures the dries quantity of evaporative pattern.

Accompanying drawing explanation

Fig. 1 is overall structure and schematic shapes.

Fig. 2 is wet drying room heat supply pipeline plane.

Figure number illustrates: 1 is dry drying room; 2 is wet drying rooms; 3A is front moisture exhausting port; 3B is tail hydrofuge; 3a is front exhaust blower; 3b is tail exhaust blower; 4 is burners; 4a is heat supply pipeline import; 4b is fire door; 4c smoke exhaust pipe; 5 is air exhausters; 5a is heat supply pipeline outlet; 5b is outlet; 6 is drying room doors; 7 is heat supply pipelines.

Detailed description of the invention

Below in conjunction with accompanying drawing, as embodiment, technical scheme is further illustrated.

See figures.1.and.2, evaporative pattern drying room exports 5a, outlet 5b by dry drying room 1, wet drying room 2, front exhaust blower 3a, tail exhaust blower 3b, burner 4, air exhauster 5, heat supply pipeline 7, front moisture exhausting port 3A and tail moisture exhausting port 3B, heat supply pipeline import 4a, fire door 4b, smoke exhaust pipe 4c, heat supply pipeline and puts the support of evaporative pattern and Automatic Temperature Control forms.Drying room front is provided with the drying room door 6 can opened with hermetically closing.

Wet drying room 2 sole arrangement has heat supply pipeline 7 and side to be provided with moisture exhausting port 3, and heat supply pipeline 7 import 4a and burner 4 are tightly connected.Fuel enters in burner by fire door 4b, and the air inlet that heat supply pipeline 7 exports 5a and air exhauster 5 is tightly connected, and one end of outlet 5b and the air outlet of air exhauster 5 are tightly connected, and the other end to stretch in dry drying room 1 and is tightly connected with dry drying room wall.

The heat energy that burner 4 produces is under the effect of air exhauster 5, the heat supply pipeline 7 of wet drying room 2 sole arrangement of warp is to heat supply in wet drying room, thus preliminarily dried is carried out to the evaporative pattern be placed on support in wet drying room 2, the moisture produced in dry run exhaust blower 3a before being arranged on front moisture exhausting port 3A place discharges.Heat energy through in wet drying room 2 arrange heat supply pipeline 7 after by directly entering in dry drying room 1 with the outlet 5b that air exhauster 5 air outlet is connected with dry drying room 1, by again dry for the evaporative pattern by being placed on support after wet drying room 2 preliminarily dried, the exhaust blower 3b of moisture through being arranged on tail moisture exhausting port 3B place of generation discharges.When temperature is too high, Automatic Temperature Control can cut off air exhauster power supply automatically, and air exhauster quits work, and temperature decreases.The flue gas that burner 4 produces is discharged by smoke exhaust pipe 4c.

Drying room two-layered steel plates is welded the interlayer of hollow, and in interlayer, add heat-preservation cotton, support and the heat supply pipeline 7 of putting evaporative pattern all adopt metal steel pipe.Select air exhauster, exhaust blower and Automatic Temperature Control that market is sold.
