Description

A kind of firing equipment of foam mold

Technical field

This utility model is related to a kind of firing equipment, refers in particular to a kind of firing equipment of foam mold.

Background technology

Foam plasticss are the internal plastics containing countless small abscesses made by with resin as raw material.Modern technologies are several All thermosettings and thermoplastic resin can be processed into foam plasticss.At present, main foam plasticss kind has polyurethane, gathers Styrene, polyethylene, polrvinyl chloride and ureaformaldehyde etc..Foam plasticss have that density is low, heat conductivity is low, hygroscopicity is low, resilience The features such as good, adiabatic and sound-absorbing sound insulation, therefore, deadener is widely used as architectural, thermal insulation is widely used as in terms of refrigeration Material, is widely used as the packaging material of quakeproof moisture-proof at aspects such as instrument and meter, household electrical appliance and artworks, in water surface operation It is commonly used for floating material.

After the moulding process of foam plasticss mainly feeds injection into foam mold, then foam mold is put into steam box lead to People's steam is heated, the pre-expanded particles in mould by thermal softening and expansion with regard to together with mutual clinkering, the taking-up from steam box afterwards Mould, is obtained foam plasticss product after cooling and demolding.

From boiler, water heating is produced steam to steam in existing steam box by boiler, steam used in steam box after become Hot water is discharged, and virtually wastes substantial amounts of water resource.

Utility model content

This utility model provides a kind of firing equipment of foam mold, and its main purpose is to overcome existing heat froth mould In the steam box of tool, water cannot be recycled wasting defect.

To solve above-mentioned technical problem, this utility model is adopted the following technical scheme that：

A kind of firing equipment of foam mold, including steam box and air inlet pipe for heat froth mould, the steam box Connected with the outlet side of boiler by the air inlet pipe, the water tank in the boiler is also connected with the steam box by a drain pipe, The air inlet pipe is located at the steam box positioned at the connection end of the upside of the steam box, the drain pipe and steam box with the connection end of steam box Lower end, it is the water pump and one first valve that boiler is flowed to from steam box that a transfusion direction is equiped with the drain pipe.

Further, first valve is electrodynamic valve.

Further, a control box being connected with first valve circuit is equiped with the outside of the steam box.

Further, a level sensor is also equiped with the steam box, the level sensor is by the control box It is connected with first valve signal.

Further, the water pump is connected with the level sensor signal also by the control box.

Further, one second valve is also equiped with the air inlet pipe.

Further, the steam box is equiped with one for sensing the infrared sensor of foam mold, the infrared sensor It is connected with second valve signal by the control box.

Compared to the prior art, the beneficial effect of this utility model generation is:

1st, this utility model simple structure, practical, by drain pipe is arranged between steam box and boiler so that steam After becoming hot water in steam box, carry out post bake during the water tank of boiler can be entered by drain pipe again and become steam repetition profit With so as to avoid wasting for heat energy, playing the effect of energy-saving and emission-reduction.

2nd, in this utility model, by arranging level sensor so that when the water level in steam box reaches default value, Signal can be sent control box by level sensor, and control box controls the startup of the first valve again, hot water is flowed in drain pipe, while Control starting mode of pump, is recycled in the water tank for enabling hot water to inflow boiler.

3rd, in this utility model, by arranging infrared sensor so that have in steam box bubble when infrared sensor is sensed During foam mould, the startup of the second valve can be controlled, so as to allow steam in boiler to enter in steam box；When no foam mold in steam box When, steam will not be then entered in steam box, saved the energy.
