Problems solved by technology

[0004] Due to the different requirements of construction sites, the demand for constant pressure and constant flow foaming devices for foam lightweight concrete equipment is also different. Therefore, the existing manufacturers of constant pressure and constant flow foam devices for foam lightweight concrete equipment are The requirements are different. Three types of machines, large, medium and small, have been produced, but the existing ones require external power supply to operate normally during use. If the power supply cannot be provided at the construction site, they will not be able to operate normally. The constant pressure and constant flow foaming device of concrete equipment needs to prepare the cement slurry in advance, which cannot be prepared in real time on the construction site according to the needs of the construction site, so it has great limitations

Abstract

The invention provides a constant voltage and constant current foaming device for foamed light concrete equipment. The constant voltage and constant current foaming device comprises a supporting unit,a material feeding unit, a mixing foaming unit, a storage unit and a control unit, wherein the supporting unit comprises a base and a displacement mechanism; the material feeding unit is arranged atthe upstream of an installation platform of the base and comprises a material feeding portion, a liquid feeding portion and a stirring portion; the mixing foaming unit is arranged on the installationplatform of the base, is located at the downstream of the material feeding unit, comprises a mixing portion, a liquid injection portion and an air feeding portion and is used for mixing material liquid and a solution added into the mixing portion and performing foaming; the storage unit is used for discharging out the material liquid after mixing foaming; and the control unit comprises a controller, a power supply device and a plurality of flow control valves and is used for controlling actions of the material feeding unit, the mixing foaming unit and the storage unit, and the power transmission end of the controller is in electric connection with the power supply end of the power supply device through a conducting wire. The constant voltage and constant current foaming device for the foamed light concrete equipment has the beneficial effects that cement slurry can be prepared on site, the device practicability is improved, the constant voltage and constant current foaming device can still be used in the construction site without external power supply, and the applicability of the constant voltage and constant current foaming device for the foamed light concrete equipment is improved.

Description

technical field [0001] The invention relates to the related field of concrete construction, in particular to a constant pressure and constant flow foaming device for foam lightweight concrete equipment. Background technique [0002] Foam lightweight concrete, also known as foam lightweight soil, foam concrete, foam cement, lightweight concrete, etc., is to introduce air, nitrogen, carbon dioxide or oxygen into the concrete slurry according to the application needs through chemical or physical means Among them, after reasonable maintenance and molding, the concrete products formed contain a large number of small closed pores and have considerable strength. Because of its light weight, thermal insulation, environmental protection and durability, and convenient construction, it is widely used in roads, tunnels, housing construction and other fields, and has developed rapidly in my country in recent years. [0003] The existing foam light soil equipment usually includes a compr...
