Abstract
The utility model discloses au automatic cleaning device of an ore pulp fluid density measurement sensor, and the automatic cleaning device comprises a pulp pipe and a tuning fork sensor which is fixed in the pulp pipe, wherein a shower pipe is arranged above the tuning fork sensor and is dead against the working part of the tuning fork sensor; a water supply pipe which is connected with the shower pipe penetrates through the wall of the pulp pipe so as to be connected with a control valve; the control valve is connected with a pressure water tank and a PLC (Programmable Logic Controller) control system; the tail part of the tuning fork sensor is connected with a tuning fork transducer through a tuning fork sleeve; and the tuning fork transducer is connected with the PLC control system. The automatic cleaning device of the ore pulp fluid density measurement sensor is simple in structure, high in cleaning efficiency, simple in installation and control manners, strong in operability and stable and reliable in work.
Description
Technical field
The utility model relates to the cleaning device of instrument and meter sensor, especially measures the automatic flushing device of the tuning fork sensor of pulp density.
Background technology
In the multiple fertile manufacturing enterprise of phosphorus; The flow of slurry volume density is measured the control index and the product quality that will be related to production; Through practice; In measuring the in-situs tester table of pulp density, a kind of plug-type tuning fork sensor relatively is fit to measure pulp density, fluid density sensor as continuously, during other quality-controlling parameters such as real-time online measuring percentage of solids or percentage have extensively been applied to produce.Yet in measuring the pulp density process, because its solids content is higher, particle is bigger; Viscosity is more high; Thereby sensor surface is often with the particle ore pulp in the tuning fork sensor process of flowing through, and time one length will cause fouling and make the sensor obstruction malfunctioning, so measures just inaccurate; The production control index will distortion, and product quality does not just guarantee.Want on the technology to make measured value accurate; Clear up with regard to pulling down the densitometer sensor after must stopping, install again after cleaning is good and measure, will increase plenty of time and labour like this to remove cleaning sensing; Increase cost of labor, brought influence also for the continuity of producing.
At present, prior art does not also have the device that the tuning fork sensor of measuring pulp density is cleaned automatically.
Summary of the invention
To the weak point of prior art, the utility model aims to provide a kind of automatic flushing device of measuring the ore pulp fluid density sensor, need not stop production guaranteeing, cleans the tuning fork sensor device automatically, overcome ore pulp to sensor stop up cause measure inaccurate.
For solving the problems of the technologies described above; The technical scheme that the utility model adopts: a kind of automatic flushing device of measuring the ore pulp fluid density sensor, comprise slip pipeline and the tuning fork sensor that is fixed in the slip pipeline, above the tuning fork sensor, shower is set; Shower is over against tuning fork working sensor position; The feed pipe that connects shower passes the slip duct wall and connects control valve, and control valve connects pressure water tank, and control valve is connected with PLC control system; Afterbody at the tuning fork sensor connects the tuning fork transmitter through the tuning fork sleeve pipe, and the tuning fork transmitter connects PLC control system.
Adopt said apparatus, when needing to clean the tuning fork sensor, PLC control system sends signal and opens control valve; Water in the pressure water tank is through feed pipe output; Shower spray tuning fork sensor can realize that remote auto cleans, after the measuring-signal of tuning fork transmitter and control valve are interlocked in PLC control system; Relevant parameter is set, then can realizes the automatic washing of tuning fork sensor.
The utility model is simple in structure, and cleaning efficiency is high, and installation and control mode are simple, workable, and working stability is reliable.
Description of drawings
Fig. 1 is the utility model structural representation;
In the accompanying drawing: 1 ore slurry pipeline, 2 showers, 3 tuning fork sensors, 4 control valves, 5 connecting flanges, 6 pressure water tanks, 7 tuning fork transmitters, 8 tuning fork sleeve pipes, 9 PLC control system.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further.
As shown in Figure 1, tuning fork sensor 3 is arranged in the ore slurry pipeline 1 through connecting flange 5, will be behind the tuning fork sensor 3 work certain hours at tuning fork sensor 3 surface scales, and it is malfunctioning that tuning fork sensor 3 is stopped up, and so measures just inaccurate.
After this device was on probation, warp is verification by tests and scruting repeatedly, and this device can accurately measure pulp density, and measurement data is true and reliable.
