Tail steam water recovery device for artificial board hot press

Abstract

The invention relates to the field of hot presses, in particular to a tail steam water recovery device for an artificial board hot press. The tail steam water recovery device comprises the artificialboard hot press, a steam generator and a first liquid storage tank. The artificial board hot press comprises a steam inlet and a tail steam exhaust port, the steam inlet is communicated with a steam outlet of the steam generator, the tail steam exhaust port is communicated with the first liquid storage tank, and a temperature control valve is arranged between the steam inlet and the steam generator; the first liquid storage tank is communicated with a second liquid storage tank, a pressure solenoid valve is arranged between the first liquid storage tank and the second liquid storage tank, thesecond liquid storage tank is communicated with the water inlet end of a water pump, the water outlet end of the water pump is communicated with a liquid inlet of the steam generator, and a pressure switch is arranged between the second liquid storage tank and the water pump and controls on-off of the water pump. The tail steam water recovery device for the artificial board hot press can reduce the labor cost, improve the heat energy utilization efficiency and reduce the steam generation energy consumption.

Description

technical field [0001] The invention relates to the field of hot presses, in particular to a device for recovering steam and water from the tail of a wood-based panel hot press. Background technique [0002] The hot press is a machine used to produce plywood and other multi-layer boards, and it is one of the most important equipment in the production of wood-based panels; it has a platform that can move up and down to apply pressure to the board body; the inside of the platform has steam or electric heating device for plate heating. [0003] Because steam heating has better thermal uniformity and thermal energy efficiency, most of the existing wood-based panel hot presses use steam heating, and the wood-based panel hot presses that use steam heating are equipped with steam inlets and exhaust outlets , the steam inlet is connected to a steam generator, such as a boiler, and the tail steam exhaust port is connected to a condensate storage tank, and the condensed water in the ...

AI Technical Summary

Problems solved by technology

[0004] Since the tail steam recovery of the above-mentioned steam-heated wood-based panel heat press is through condensation and manual extraction, the water temperature of the condensed water returned to the steam generator is relatively low, which causes the steam generator to recover the heat of the condensed water. It consumes a lot of energy, and workers need to take care of it and manually start and shut down the water pump during the recycling process, and the labor cost is relatively high.
