Abstract
The utility model relates to a coal dressing production field, in particular to pressure filter pan feeding pressure control system. This pressure filter pan feeding pressure control system, including the filter -pressing control system who connects the pressure filter, its characterized in that: install pressure sensor in the straining chamber of pressure filter, pressure sensor passes through pressure controller and connects output controller, and output controller was connected to long controller when filter -pressing control system passed through, and output controller connects feeding pump. The utility model discloses simple structure, convenient to use, but material accident and improvement pressure filter output are spouted in furthest's reduction, effectively protect the feeding pump motor, replace this motor to start the facility, effectively protect filter plate and filter cloth simultaneously, save into the product cost.
Description
（One）Technical field
The utility model is related to coal separation production field, more particularly to a kind of filter press feed pressure control system.
（Two）Background technology
In the industries such as coal separation, chemical industry, environmental protection, in a large number fine granular materials are dehydrated using plate and frame filter press, sheet frame
The filter press course of work be by pan feeding pump come realize pan feeding and formed filter chamber pressure, the pressure make penetration by liquid filter layer and
Filter cloth is deviate from.
Plate and frame filter press filter chamber structure presses together for adjacent two pieces of filter plate frames under filter press end to end plate pressure, shape
Into sealing space.
It is the speed of production for improving filter press in filter press production process, generally requires to increase feed pressure, but,
Increasing feed pressure can offset the pressure of aluminium sheet frame, even back down filter plate and cause material spray accident；If increasing the oil of head plate
Cylinder pressure can effectively avoid backing down filter plate material spray, but excessive oil cylinder working-pressure can damage filter plate frame by pressure, cause the filter plate life-span
Lower.So, oil cylinder working-pressure and feed pressure can only be respectively maintained in certain limit.
In production, the feed pressure that Field Force uses typically all is set in allowed band, but, when pan feeding starts,
Mud has stronger impulsive force when feeding to filter press filter chamber by pipeline from the pump housing, and now instantaneous pressure is very high, easily backs down
Filter plate causes material spray；Or, pan feeding leading portion, because concentration of hydraulic mixture is low, in filter chamber much filtrate filter layer, now, aluminium sheet is not formed
It is maximum that frame pressing hermetic unit is subject to the pressure of filtrate, if this maximum is placed exactly in bezel pressure weakness, meeting
Material spray is caused, generally, after pan feeding carries out a period of time, much filtrate filter layer has been formed in filter chamber, the press filtration cycle
Just can normally complete.So, production scene typically sets feed pressure all in relatively low numerical value, is extremely difficult to high production speed
Degree.
（Three）The content of the invention
The utility model is in order to make up the deficiencies in the prior art, there is provided a kind of simple structure, it is easy to use, safe efficiently
Filter press feed pressure control system.
The utility model is achieved by the following technical solution：
A kind of filter press feed pressure control system, including the press filtration control system of connection filter press, it is characterised in that：Pressure
Pressure sensor is installed, pressure sensor connects o controller, press filtration control by pressure controller in the filter chamber of filter
System connects o controller, o controller connection pan feeding pump by duration controller.
The utility model devises a set of automation control system, by real-time prison of the press filtration control system to filter press
Control, is easy to give duration controller by signal transmission, with by the startup of output controller controls pan feeding pump；In the feeding of pan feeding pump
During, the pressure sensor in filter press filter chamber detects at any time pressure limit, in order to pass through pressure controller to output control
Device sending signal processed, the feeding of real-time adjustment pan feeding pump is how many.
More excellent technical scheme of the present utility model is：
Frequency converter A and frequency converter B connection pan feeding pump that the o controller connects in parallel, by different frequency conversions
Device adjusts the high pressure feed or low pressure feed of a pan feeding pump, meets production status；O controller can also directly with two
Different pan feeding pump connection, for high pressure feeding and the switching of low pressure feeding.
It is long to be provided with start, pan feeding early stage, each time phase in pan feeding later stage in the duration controller, for adjusting pan feeding
Feeding amount of the pump in different times.
Pressure set points are provided with the pressure controller, by the way that the pressure gathered from pressure sensor and pressure are set
Definite value compares, and grasps and adjust the running status of filter press.
The utility model simple structure, it is easy to use, can to greatest extent reduce material spray accident and improve filter press yield,
Effective protection pan feeding pump motor, replaces the electric motor starting facility, while effective protection filter plate and filter cloth, save into product cost.
（Four）Description of the drawings
The utility model is further described below in conjunction with the accompanying drawings.
Fig. 1 is structural representation of the present utility model.
In figure, 1 press filtration control system, 2 pressure sensors, 3 pressure controllers, 4 o controllers, 5 duration controllers, 6
Frequency converter A, 7 frequency converter Bs.
（Five）Specific embodiment
Accompanying drawing is a kind of specific embodiment of the present utility model.The embodiment includes the press filtration control system of connection filter press
2, pressure sensor 2 is installed in the filter chamber of filter press, pressure sensor 2 connects o controller 4 by pressure controller 3,
Press filtration control system 1 connects o controller 4, the connection pan feeding pump of o controller 4 by duration controller 5；The output control
Frequency converter A 6 and the connection pan feeding pump of frequency converter B 7 that device processed 4 connects in parallel；Be provided with the duration controller 5 start,
Pan feeding early stage, each time phase in pan feeding later stage are long；Pressure set points are provided with the pressure controller 3.
The utility model is a set of automation control system, and duration controller 5 can set start, pan feeding early stage, pan feeding
Each time phase in later stage is long, and press filtration control system 1 is that duration controller 5 provides filter press standby ready signal.Duration controller 5 connects
To after ready signal, send this pan feeding to o controller 4 and start and according to this by each phase signal of duration set in advance transmission；
Pressure controller 3 can set each phase pressure value, and pressure controller 3 is connected to after the pressure signal that pressure sensor 2 is sent and sets
Definite value compares, and the application that accelerates and slow down is sent to o controller 4；O controller 4 is according to duration controller 5 and Stress control
The signal that device 3 is sent controls respectively the operating of pan feeding pump, and pan feeding early stage pan feeding pump low-pressure operation is pressurized to low pressure to the pan feeding later stage
After rated pressure, high-pressure service is reconverted into, the speed-raising of pan feeding pump is pressurized to the specified feed pressure of filter press.Complete pressing time
Afterwards, pump stops.
The utility model adapts to only be equipped with the press filteration system of a pan feeding pump, and o controller 4 is by the He of frequency converter A 6
The switching of frequency converter B 7, realizes adjusting the high-low pressure switching of pan feeding pump operation pressure, completes whole pan feeding process；This practicality is new
Type can also be used for connection production while two different pressures pan feeding pumps.
