Abstract

The invention discloses an adjustable phosphate dosing device and belongs to the technical field of incrustation treatment. The device comprises a dosing box; a rotating shaft and a stirring knife are arranged in the dosing box; a first motor and a feed hopper are arranged on the upper part of the dosing box; a first valve and a pushing assembly of a discharge hole are arranged on the lower part of the dosing box; a water boiling box is arranged below the discharge hole; a stirring shaft and a stirring rod are arranged in the water boiling box; a second motor and a water inflow pipe are arranged at the top surface of the water boiling box; and a water pump and a filtering assembly are arranged below the water boiling box. According to the device of the invention, the dosing box is arranged, phosphate enters the dosing box from the feed hopper, the first motor is started to drive the rotating shaft to rotate, so that the stirring knife is driven to stir materials, the materials are prevented from being stacked together, and the reaction efficiency of the materials and hot water is reduced; the first valve is opened, a sliding block is pushed leftwards, a pushing plate and a pushing rod are driven to move leftwards, the discharging speed and the use dosage of the phosphate are conveniently controlled; and the second motor drives the stirring shaft and the stirring rod to rotate, and therefore the reaction rate of the hot water and the phosphate is increased.

Description

technical field [0001] The invention relates to the technical field of boiler scale treatment, in particular to an adjustable phosphate dosing device. Background technique [0002] Power auxiliary equipment refers to auxiliary machinery for power station production equipment. It is an important part of power station equipment and an indispensable equipment for the normal operation of power station equipment. [0003] Power auxiliary equipment mainly includes: boiler slag removal equipment, boiler ash removal equipment, coal handling and crushing equipment, water treatment equipment, flue gas duct series equipment and electric valve devices, etc. [0004] Phosphates are generally used in detergents as water softeners. [0005] After use, the electric boiler will leave a thick layer of scale on the inner wall of the boiler. Therefore, in order to maintain the normal operation of the boiler, it is necessary to add trisodium phosphate to the boiler water and maintain a certain ...
