Liquid-state reagent automatic adding device

Abstract

The invention discloses a liquid-state reagent automatic adding device in the beneficiation process. The device is provided with a reagent storage box, a reagent balance box, an electric integral reagent valve and a programmable control cabinet; a reagent inlet of a reagent adding valve is formed in the side surface of a pneumatic reagent adding valve, and is connected with a reagent passing pipeII; a reagent outlet is formed in the bottom of the pneumatic reagent adding valve; the lower end of the reagent adding extension rod is connected with a valve element of the reagent adding valve; andthe other end of the reagent adding extension rod is connected with a cylinder. A floating ball valve in the reagent balance box realizes timely feeding of reagents; the reagent pressure difference in the reagent balance box is stable, so that the technical problem of instable reagent supply quantity caused by different front and back pressure differences due to direct reagent supply by the reagent storage box is solved; the diameter of a reagent passing pipe I is not smaller than the diameter of the reagent passing pipe II, so that stable reagent feeding and discharging of the reagent balance box can be maintained; and the pneumatic reagent adding valve is controlled through the electric integral reagent valve at the upper end of the reagent adding extension rod to realize the reagent feeding and discharging automation, so that the working environment is optimized, the labor intensity is relieved, and the production quality and efficiency are improved.

Description

technical field [0001] The invention belongs to the technical field of mineral processing equipment, and relates to a liquid medicine adding device in the mineral processing process, in particular to an automatic liquid medicine adding device. Background technique [0002] In mineral processing, most of the existing liquid agent automatic adding devices adopt the automatic quantitative adding method of electromagnetic flow meter and float valve liquid level balance, and then use electromagnetic valve to perform opening degree or on / off frequency action. This addition method is not completely suitable for mineral processing liquid reagents with a large concentration range (such as lime emulsion 10% to 40%), high viscosity (such as water glass), and a wide range of additives (such as foaming agent oil 0.5ml to 100ml / min. ), pharmaceuticals often contain impurities with high hardness and particle size and other process conditions, such as: [0003] 1. Electromagnetic flowmeter...

Problems solved by technology

[0004] 2. Solenoid valve mode: Due to the nonlinear characteristics of its electromagnetic torque, the action torque of the solenoid valve core rises from the minimum to the maximum when the power is turned on, and the action torque of the solenoid valve core is prone to occur when it is used for high-concentration and multi-impurity liquid medicine. Insufficient, resulting in incomplete opening, stuck, making the dosing valve invalid

[0005] 3. Mechanical floating ball liquid medicine balance tank: the conventional float ball control liquid level method, the float ball is above the balance liquid level, which requires a liquid level difference, occupies part of the height of the balance liquid level tank, and the effective volume is not fully utilized
