Description
Technical field
The utility model relates to feed system field more particularly to liquid quantitative feeding systems.
Background technique
In liquid fertilizer production, according to the condition of production technology need that liquid material is added into reaction kettle.At present, liquid
State material is generally stored in a manner of storage tank, and the determination of liquid level carrys out rough calculating with tape measure to obtain, and liquid material is with hand
It is dynamic to open water pump to convey required raw material, such operation there is numbers of repetition relatively more, large labor intensity, weighing error
Greatly, a series of problems, such as working efficiency is low, poor product quality.Simultaneously as non-return valve and the pipeline disengaging of exit of pump installation
The reasons such as the height difference of mouth can accumulate liquid after water pump shutdown in pipeline, will a large amount of liquid of remaining if pipeline height difference is larger
Body and certain pressure, so cause valve destroy, pipe leakage situations such as.
Summary of the invention
In order to solve deficiency in the prior art, the purpose of this utility model is to provide a kind of precisely quantitative and automatic controls
The liquid quantitative feeding system of system.
To achieve the above object, the utility model uses following technical scheme:
Liquid quantitative feeding system, including liquid tank, reaction kettle and water pump, the outlet end of the liquid tank by water valve with
The arrival end of water pump connects, and further includes three-way magnetic valve, frequency converter and central control system, and the reaction kettle lateral wall is equipped with pair
Its weighing unit weighed, the three-way magnetic valve are placed in the top of reaction kettle, the arrival end of three-way magnetic valve and going out for water pump
The connection of mouth end, the outlet end A of three-way magnetic valve are connect with the feed inlet at the top of reaction kettle, the outlet end the B connection of three-way magnetic valve
To the arrival end of water valve；The input terminal of the water pump is electrically connected with frequency converter, is equipped with liquid level sensor, the title inside liquid tank
Weight unit, three-way magnetic valve, frequency converter, water pump and liquid level sensor are electrically connected with central control system respectively.
The feed system further includes the dynamic display screen being electrically connected with central control system, and the central control system is by level sensing
The information of device and weighing unit is shown on dynamic display screen.
The central control system is using PLC as main controller.
The utility model using the above structure, has the advantages that；This system uses the water pump of frequency conversion, may be implemented
The variation of pump motor revolving speed, it is precisely quantitative.Meanwhile there are also the functions of pressure release for system, after water pump shutdown may be implemented, in pipeline
Excessive liquid will not be accumulated, reduce pipeline pressure；For central control system using PLC as main controller, the open and close of valve are automatic
Control, high degree of automation, and also technological parameter can be most clearly shown on dynamic display screen, and operator can slap at any time
Hold the condition of production.
Detailed description of the invention
The utility model is described in further details below in conjunction with the drawings and specific embodiments；
Fig. 1 is the schematic diagram of the utility model.
Specific embodiment
As shown in Figure 1, the utility model includes liquid tank 1, reaction kettle 2 and water pump 3, the outlet end of the liquid tank 1 is logical
It crosses water valve 4 to connect with the arrival end of water pump 3, further includes three-way magnetic valve 5, frequency converter 6 and central control system 7, the reaction kettle 2
Lateral wall is equipped with the weighing unit 8 weighed to it, and the three-way magnetic valve 5 is placed in the top of reaction kettle 2, three-way magnetic valve 5
Arrival end connect with the outlet end of water pump 3, the outlet end A of three-way magnetic valve 5 is connect with the feed inlet at 2 top of reaction kettle, three
The outlet end B of three-way electromagnetic valve 5 is connected to the arrival end of water valve 4；The input terminal of the water pump 3 is electrically connected with frequency converter 6, liquid tank
1 inside is equipped with liquid level sensor 9, and the weighing unit 8, three-way magnetic valve 5, frequency converter 6, water pump 3 and liquid level sensor 9 are distinguished
It is electrically connected with central control system 7.
The feed system further includes the dynamic display screen being electrically connected with central control system 7, and the central control system 7 passes liquid level
The information of sensor 9 and weighing unit 8 is shown on dynamic display screen, and operator can grasp the condition of production at any time.
The central control system 7 is using PLC as main controller.The open and close of valve are to automatically control, high degree of automation.
Working principle of the utility model is: unlatching water pump 3 will be in liquid tank 1 by water pump 3 firstly, opening water valve 4
Liquid material extraction opens 5 arrival end of three-way magnetic valve and the outlet end A of 2 top of reaction kettle, is just starting to take out liquid material
When, since liquid material is more, frequency converter 6 adjusts the electric machine frequency of water pump 3, and material is extracted into reaction kettle 2 using high frequency high revolving speed
In, when showing that material reaches required 80 or so percent on weighing unit 8, frequency converter 6 changes the electric machine frequency of water pump 3,
Pumping material is carried out using the slow-speed of revolution, after liquid material reaches reaction aequum, the three-way magnetic valve 5 of 2 top of reaction kettle is exported
A is held to close, water pump 3 is out of service.Then, it after liquid material accurate quantification, is reacted in reaction kettle 2.Finally, in water pump
After 3 shut down, since there are inertia for motor, has a large amount of liquid and accumulate in pipeline, at this point, control three-way magnetic valve 5, by it
The outlet end B is opened, and residual liquid is flow back into the inlet of water valve 4.
