Description
Technical field
This utility model belongs to the design of mine automation system and the technical field manufactured, particularly to a kind of slurry of coal washing plant pressure filter automatic feed preparation system.
Background technology
Pressure filter is as a visual plant of coal preparation plant's coal slime processing procedure, and traditional pressure filter is got the raw materials ready and mostly is artificial power frequency startup thickener underflow pump, then passes through and observes into charging basket liquid level, manually stops pan feeding.Its feeding system operational approach mostly is power frequency startup pan feeding pump manually at present, from higher level equipment thickener underflow dnockout to entering charging basket, then again from enter charging basket deliver to pressure filter carries out next step operation.This manual operations way ubiquity electrical fault rate is high, the shortcomings such as automaticity is low, and frequent operation labor strength is big., thus current pressure filter stock preparation system must be carried out the Automation Design, thus improving the work efficiency of workman and equipment.
Summary of the invention
The technical problem that this utility model is low in order to solve pressure filter feeding system automaticity, design provides a kind of coal preparation plant coal slime pressure filter automatic feed preparation system.
The technical solution of the utility model is: a kind of coal washery pressure filter automatic feed preparation system, including thickener, motor, permanent-magnet speed governor, underflow pump, coal slime bucket, pressure filter, switch board, host computer；Described thickener connects coal slime bucket by underflow pump, coal slime bucket connects pressure filter, underflow pump is connected to motor and permanent-magnet speed governor, coal slime bucket is provided with ultrasonic liquid level sensor, ultrasonic liquid level sensor, permanent-magnet speed governor connect switch board, and described switch board connects host computer.
Compared with prior art, first this utility model installs ultrasonic liquid level sensor detection coal slime bucket real-time level on coal slime bucket, when liquid level is lower than the liquid level lower limit set, system starts permanent-magnet speed governor automatically thus controlling thickener underflow pump to carry out feed toward coal slime bucket, when coal slime bucket liquid level arrives the upper limit, it is automatically stopped permanent-magnet speed governor, stops feed.Simultaneity factor is also equipped with human-computer exchange function, can manually and automatically be operated by the touch screen on switch board at the scene, and field data is uploaded to control room host computer also by ethernet communication, reduce labor strength, improve automatization and the level of IT application of coal washery, reducing the fault rate of motor, the continuous and steady operation of safeguards system, energy-saving effect is notable simultaneously.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1-thickener, 2-motor, 3-permanent-magnet speed governor, 4-underflow pump, 5-coal slime bucket, 6-ultrasonic liquid level sensor, 7-field control cabinet, 8-host computer, 9-host computer, 10-pressure filter.
Detailed description of the invention
Below in conjunction with accompanying drawing 1, this utility model is described further: a kind of coal washery pressure filter automatic feed preparation system, shown in Fig. 1, including thickener 1, motor 2, permanent-magnet speed governor 3, underflow pump 4, coal slime bucket 5, pressure filter 10, switch board 7, host computer 9, described thickener 1 connects coal slime bucket 5 by underflow pump 4, coal slime bucket 5 connects pressure filter 10, underflow pump 4 is connected to motor 2 and permanent-magnet speed governor 3, coal slime bucket 5 is provided with ultrasonic liquid level sensor 6, ultrasonic liquid level sensor 6, permanent-magnet speed governor 3 connects switch board 7, described switch board 7 connects host computer 9.
Described switch board 7 is provided with human-computer exchange touch screen 8, and switch board 7 connects host computer 9 by Ethernet.
The ultrasonic liquid level sensor 6 installed on coal slime bucket 5 detects coal slime bucket liquid level in real time, when liquid level is lower than the liquid level lower limit set, system automatically starts permanent-magnet speed governor 3 thus the underflow pump 4 that drive motor 2 controls under thickener 1 carries out feed toward coal slime bucket 5, when coal slime bucket 5 liquid level arrives the upper limit, it is automatically stopped permanent-magnet speed governor 3, stops feed.This device is also equipped with human-computer exchange function simultaneously, can manually and automatically be operated by the touch screen 8 on switch board 7 at the scene, and field data is uploaded to control room host computer 9 also by ethernet communication, reduce labor strength, improve automatization and the level of IT application of coal washery, reducing the fault rate of motor, the continuous and steady operation of safeguards system, energy-saving effect is notable.
Selecting permanent-magnet speed governor 3 to replace traditional soft start and converter as the speed control device of thickener underflow pump, have and substantially reduce vibration, reduce the fault rate of motor and pump, extension device service life, energy-saving effect is notable simultaneously.
