Continuous type full-automatic chemical feeding device

Abstract

The invention provides a continuous type full-automatic chemical feeding device. The continuous type full-automatic chemical feeding device comprises a dry powder feeding system, a dehumidification and drying system, a dry powder pre-mixing system, a water supplying system, a combined groove body, a stirring system and an automatic control system, wherein the dry powder feeding system comprises a dry powder feeding machine; the bottom of the dry powder feeding machine is connected with the dehumidification and drying system; the dehumidification and drying system comprises a spiral rod and a spiral sheet; the spiral rod is connected with a motor I; the spiral rod is of a hollow structure; a silica gel heating sheet is arranged on an inner wall of the spiral rod; the spiral sheet is provided with rectangular grooves and arc-shaped grooves; each rectangular groove is internally provided with a PTC (Positive Temperature Coefficient) heating sheet. The continuous type full-automatic chemical feeding device is provided with the dehumidification and drying system, the effects of preventing powder from being condensed, heating and keeping heat are realized and a condition that chemical powder is affected with damp and caked or goes bad is avoided; a chemical dissolving tank is provided with a material level instrument and a storage groove is internally provided with a liquid level meter, and metering of chemical liquid in the whole chemical feeding device is monitored at any time; the chemical feeding device is automatically started and stopped through a controller, so that the device is continuously operated and automation is realized; the operation difficulty and the labor cost are reduced.

Description

technical field [0001] The invention relates to a medicine adding device, in particular to a continuous automatic medicine adding device. Background technique [0002] The screw feeder is a good choice to quantitatively transport the powder from one process to the next process, but in the past work process, the powder often agglomerated or deteriorated due to moisture. [0003] At present, the dosing device used for sewage treatment has a low degree of automation and is mostly manual dosing. The manual dosing procedure is cumbersome and requires a special person to do the dosing regularly, which is a waste of labor. Moreover, the manual dosing cannot be accurately dosed, resulting in poor treatment effect. Stable, the waste of medicine is large, and manual dosing cannot respond to system parameters in a timely and accurate manner. When the system operating conditions fluctuate, there is often a lag in dosing, which affects the effect. Contents of the invention [0004] Ai...
