On-line adding device for gypsum board water reducing agent

Abstract

The invention discloses a gypsum board water reducing agent on-line adding device which comprises a storage tank used for storing a water reducing agent, and a water level monitoring module used for monitoring the water level of the water reducing agent is arranged in the storage tank. The storage tank is connected with a multi-path drainage filter which is used for multi-path drainage and filtering the water reducing agent so as to cut off any path under the condition that the overall drainage of the water reducing agent is not influenced, and the multi-path drainage filter is used for adding the filtered water reducing agent into a gypsum mixing machine through an adding pipe; according to the multi-path drainage filter, any path can be cleaned and replaced under the condition that normal transmission of a water reducing agent is not influenced, and production of gypsum boards is not influenced, so that the cost of manually cleaning pipelines is greatly saved; the content of the water reducing agent can be monitored in real time, and the amount of the water reducing agent can be increased in time.

Description

technical field [0001] The invention relates to the technical field of gypsum board production, in particular to an on-line addition device of a gypsum board water reducing agent. Background technique [0002] In the production process of gypsum board, the theoretical water consumption for hydration of hemihydrate gypsum is 0.186, but in the actual production process of gypsum board, in order to improve the fluidity of the slurry, mixing water larger than the theoretical water consumption is often added, and the excess mixing water is often added. The hydrated water evaporates during the drying process of the gypsum board, resulting in more open pores in the gypsum board. The open pores caused by the evaporation of water vapor in the gypsum board lead to poor lap compaction of the gypsum crystals, reduced strength and toughness of the gypsum board, and poor water resistance of the board. The water reducing agent is a surfactant, which has a dispersing effect on the gypsum p...
