Summary of the invention

In order to solve to need often to go the case where checking limewash agitator and increasing workload, the present invention provides one kind Limewash agitator anti-blockage method, it by limewash agitator and discharge opening pipeline install additional flowmeter, motor-driven valve and The equipment such as liquidometer, come it is intelligent the case where judging whether putty, if putty just triggers sound-light alarm equipment, to notify operator Member handles, such operator just need not timing daily check whether putty, save time and efforts.

The present invention is to solve technical solution used by its technical problem: the setting of agitator discharge opening pipeline is being stirred On the discharge opening pipeline of agitator a flowmeter and a motor-driven valve is arranged, at the bottom of agitator ladle body in the bottom for mixing bucket A liquid level sensor is arranged in portion, and on the column on or near the ladle body of agitator, a controller and sound-light alarm is arranged Equipment respectively sets flowmeter, motor-driven valve, stirring motor, liquid level sensor and sound-light alarm equipment access controller, motor-driven valve It is set to manually adjustable, adjusts the aperture of motor-driven valve according to actual needs, and then adjust the flow of agitator discharge port, Flowmeter and liquid level sensor send the liquid level signal of the discharge port flow of limewash agitator and agitator to control respectively Device, controller have manual mode and automatic mode, and in a manual mode, controller does not issue any order, when setting is to automatically When mode, the agitator liquid level that liquid level sensor is measured is more than regulation liquid level, such as at 30 centimetres or more, automatic mode just meeting It comes into force, controller can automatically adjust the frequency and triggering sound-light alarm equipment of stirring motor according to the flow of agitator discharge port Controller attonity when Deng, normal use, if the discharge port flow that flowmeter is measured reduces amplitude when within 10% range, control Device processed is failure to actuate, if flow reduces amplitude at 10% or more, controller, which issues order, allows the frequency of stirring motor to increase, 10-30 If the flow after second in discharge opening pipeline becomes larger, restore the frequency of stirring motor, if after the frequency of stirring motor increases, discharging Discharging flow in mouth pipeline does not rise still, then increases the aperture of motor-driven valve, discharge port is made to become larger, if the aperture of motor-driven valve Flow does not rise still after becoming larger, then controller issues order, allows sound-light alarm equipment to sound an alarm, before notifying operator It handles in time, there is the case where putty.

The principle of the present invention is: when the liquid level of limewash agitator is at 30 centimetres or more, mounted in going out for agitator bottom After electrically operated valve on material mouth pipeline is opened, due to there is the effect of the pressure of water, limewash outflow is just had in pipeline, flowmeter is just Flow can be measured, if flowing out without limewash, illustrates that pipeline is unsmooth, it is possible to have lime siltation, at this moment can be stirred by increasing The aperture of the stirring frequency and electrically operated valve of mixing motor carries out dredging pipeline, if flow does not still increase, illustrates that pipeline deposits Lime it is more severe, this when just needs operator to come to handle in time, in order to avoid cause bigger siltation to influencing Production.

The invention has the advantages that under normal circumstances, control system can automatically process, when serious situation occurs, There is the risk of putty, controller can trigger sound-light alarm equipment, and operator is allowed to come to handle, and the risk of putty is reduced In bottom line, to reduce loss.
