The present invention is automatic preparation, the adding set of a cover dilution, stirring and metering flocculant solution.The concentration range of making up a prescription: 0.1%～0.5%, preparation amount 5～20m
3/ h.
The device operation principle of preparation flocculant:
Device for preparing flocculating agent of the present invention is made up of dry powder chemicals dosing plant, preparation vessel, line pump, digester, storage tank, mixer, flowmeter, liquid level gauge etc.
The powdery flocculant is fed and is stored in the feed hopper of dress dry powder.During dose out powders, feed hopper down coversion self-conveyor feed feeds material in the pigment blender, and after the pigment blender added entry, water mixed with granular material, and mixture gets into to stir in the preparation vessel and is mixed.After medicament prepares, employ line pump certainly and squeeze in the digester, further stir, slaking.Store the adding set use of supplying with flocculant to storage tank through the soup of configuration, slaking.
The adding set operation principle of flocculant:
Medicament is measured multiple spot on demand by the screw pump of frequency control and is added in the feed pipe remove defecator, the guide shell, and the charging medicament feeds defecator with after material fully mixes through multiple arrangements such as diluted mixture devices.
If go in the defecator material deposition too slow, promptly send signal to screw pump, quicken the output flow that motor speed is controlled screw pump; Too fast perhaps will the reduction of material deposition adds dose in the defecator if go, and then reduces motor speed automatically.
The motor of frequency conversion self-conveyor feed is gap work, and the working time is controlled by PLC, and the required concentration of making up a prescription can be set the concentration range of making up a prescription: 0.1%～0.5% by the user.
Preparation vessel is furnished with mixer, liquid level gauge, is provided with a liquid level high position, inferior low level, 3 signal sender points of low level, is used to send signal.Liquid level stops to add water when arriving a high position; Mixer stopped to stir when liquid level was lower than time low level; Liquid level stops line pump and carries when arriving low level.
Line pump is used for the medicament that disposes in the preparation vessel, stirs is added in the digester., the preparation vessel liquid level then stops when arriving low level, a digester liquid level arrival high position in the line pump course of work.
Digester is furnished with mixer, liquid level gauge, is provided with a liquid level high position, inferior low level, 3 signal sender points of low level, is used to send signal.
Storage tank is furnished with liquid level gauge, is provided with a liquid level high position, inferior low level, 3 signal sender points of low level, is used to send signal.Storage tank is communicated with digester, and liquid level stops the line pump dosing when arriving a high position; Mixer stopped to stir when liquid level was lower than time low level; Liquid level stops screw pump and carries when arriving a high position.
The cell body pattern of device for preparing flocculating agent is three grooveds, the combination form of preparation vessel, digester and the storage tank that promptly connects successively.
Fluid level transmitter is realized accurate measurement and the transmission high to volume, the liquid of water, oil and pastel according to the principle of ultrasonic wave or radar reflection.
The adding set of this cover flocculant is the screw pump parallel operation mode of many frequency controls, and every road is added pipeline and is equipped with a cover electromagnetic flowmeter, to satisfy metering, the control that corresponding dense groove flocculant adds.The screw pump rotating speed can need be set, regulated by the dense groove feeding quantity of correspondence.
Control cabinet is being controlled whole flocculant preparation, adding set, has two kinds of debugging mode and automatic modes available.Join touch-screen (HMI) man-machine interface, show state and data are user-friendly in real time.
Above embodiment is only in order to technical scheme of the present invention to be described but not to its restriction; Although the present invention has been carried out detailed explanation with reference to the foregoing description; The those of ordinary skill in said field is to be understood that: still can specific embodiments of the invention make amendment or replacement on an equal basis; And do not break away from any modification of spirit and scope of the invention or be equal to replacement, it all should be encompassed in the middle of the claim scope of the present invention.
