Embodiment 1

[0046] Example 1, as Figure 1 to Figure 10 As shown, a drying automatic control system using steam condensate as heat source, the control system is an automatic control system that uses its steam condensate and residual steam as radiator heat source to dry white molds and yellow molds

[0047] The control system includes a main pipeline 1 and an electronic electric actuator 1001. The main pipeline 1 is connected with a pipeline 2 and a steam branch pipeline 3. A steam ball valve 2001 is arranged between the pipeline 2, the steam branch pipeline 3 and the main pipeline 1, and the steam passes through. The main pipeline 1 enters the workshop and is controlled by the electronic electric actuator 1001. After passing through the electronic electric actuator 1001, the steam is divided into two paths. One is to supply steam to the workshop on the second to fifth floors through the pipeline 2, and the other is to pass the steam branch pipeline. 3 Supply steam to the condensate reserv...

Abstract

The invention discloses an automatic drying control system with steam condensate as a heat source. The control system is an automatic control system which utilizes the steam condensate and residual steam as the heating radiator heat source for drying a white die and a yellow die. The automatic control system comprises drying houses. Each drying house is connected with a steam condensate storage pool, wherein the steam condensate storage pool is connected with a steam lateral pipeline, a condensate and residual steam recovering main pipeline, a hot water supply pipeline and a returned water main pipeline of the drying house. The automatic drying control system has the beneficial effects that running is reliable, stable and efficient, the drying quality is improved, the cast quality is improved, the loss on defective products is reduced, energy sources are saved, and the cost is reduced.

Description

technical field [0001] The present invention relates to an automatic drying control system using steam condensed water as a heat source and its implementation method, in particular to a process suitable for lost foam casting, which uses steam condensed water and residual steam as a heat source to dry white molds and yellow molds, and A continuous production casting drying production line with a high degree of automation. Background technique [0002] Lost foam casting process: pre-foaming EPS or copolymers with steam → molding machine using steam to cure the white mold → drying room using steam heat exchanger to dry the white mold → dipping the white mold with refractory coating → using the drying room The steam heat exchanger dries the paint (yellow mold) once → dips the yellow mold twice with refractory coating → uses the steam heat exchanger to dry the paint (yellow mold) twice in the drying room → dips the yellow mold n times with refractory coating →The drying room use...
