The sewage disposal of Xinjiang adds the overall scheme of the medicine device automatically
Add the intersection of medicine and the intersection of device and use add medicine device whether a have, offer medicine, stir, transport liquid, automatically control with integrative complete sets, collect and lose the dehydration process system on the original water, boiler feed water, ground of oil field where he is widely used in the power plant, various medicine systems and process systems of the waste water of petrochemical industry. Such as throw, add coagulant, phosphate, the intersection of ammonia and liquid, lime water, water quality stabilizer ‘ Delay and lose pharmaceuticals) , hinder the intersection of dirt and pharmaceutical, liquid insecticide,etc.. The structural principle of the work: Add the medicine device from solution case mainly, stir the case ‘ Take the agitator) , measurement pump, the intersection of liquid and location count, not automatically controlled cupboard, pipeline, valve, check damper, manometer, filter, base, escalator,etc., make up ‘ Can dispose according to user’s actual requirement) . Add the medicine device according to the necessary medicine density, formulate in stiring the case, put into solution case after it is even to stir by the agitator, with the measurement pump (add the medicine pump) Send solutions formulated in clicking or designated system of offering medicine. Adding the medicine device in a complete set has compact, safe and simple, such characteristics as operation is simple and convenient. This device can also carry on the pointed design, essential part of disposition according to the request of user’s different technological process, realize function suit ‘ If control automatically and long-range) , economical and practical [9 ].
Overall scheme of chapter two
2.1 whole devices of introductions
On-the-spot picture of sewage disposal of Fig. 2.1
( 1) Originally design consulting the automatic medicine system craft of sewage treatment plant of crossing of Zhuzhou county to design, such as Fig. 2-1, this system has high and accurate measuring apparatus, has avoided wasting, easy operation is maintained, make the apparatus more human orientation, have powders and liquid state (apolegamy) Automatic the intersection of feedstock and function design and resist, condense, heat go wet function, a unique one dilute structure online, expand ability of running of the apparatus, there is the proportion that allocates the function, can adjust the density of medicinal solution disposed arbitrarily according to the actual demand, make medicinal solution that formulate to be density even and moderate, through programmable the intersection of PLC and device, available to realize, await the opportune moment the intersection of time and automatic intermittence or stop stir function alternately, make medicinal solution formulated keep most adding the result of use forever, formulate the corresponding sensor, make the control of a whole set of device more complete, can also select the man-machine interface for use and control the system.
( 2) Make up a prescription for two cases of superposing type in its characteristic of apparatus, the floor space is small, medicinal solution is steady in density, the batch active and high continuously, the powder vacuum of material suck or the loud bag is airtight shoots adding, dust is not polluted and lightened artificial labour intensity, is not limited by the shape of the supplies, can reach the firm liquid state and concurrently use, the dry powder is furnished with the pneumatic valve for the material export, and electricity heats the system,
Know a hall, prevent the material powder from being made moist and lumped effectively, easy to operate, can adopt the Chinese menu, the man-machine interface was controlled, one pair of spiral shell’s poles pushes the material, has not pulsed, batching accuracy is high, it is with low consumption and can save the cost of lump-sum input that run, the automatic intensity is high, does not need to look after manually, the service is complete, turn-key project.
2.2 main structure
1)Framework: Welded by Q235 square steel and angle steel, played the function of supporting other parts. 2)The dry powder sucks the material system: Sucked material electrical machinery, hose, sucked material head, hopper etc. to make up.
3)Push the material and dissolve the system: Moderate plane, dry powder push the intersection of material and pairs of the intersection of spiral shell and pole, mixer, the intersection of water and person who penetrate, stainless steel agitator and prepare / store pot,etc., make up;
4)The system of supplying water: Made up of valve, filter, electromagnetic valve, manometer, pipe fittings,etc.; 5)Mix water penetrating device: Unique effusive device, can make soak medicine to atomize and disperse in advance.
6)Control system: Material location turned on or off ‘ Low-order alarm of the dry powder) , electromagnetic the valve ‘ Enter water electromagnetic valve and arrange the mud electromagnetic valve and put the liquid electromagnetic valve) , liquid-level switch ( Control and prepare / store the liquid location of pot) , switch board ( The main electric component selects Snide for use) , measurement pump ( Two measurement pump frequency converters) , hand over the material (adopt pair, transport while being spiral, has not pulsed spirally out the material, accomplish even continuously, the batching is accurate) , medicinal solution stir .
Design 1 set to add the medicine device automatically and is shown as Fig. 2.2 and Fig. 2.3. Is this equipment installation managing? ? Nearby, opened and put the material valve and can be mix with the pipelined after finishing making up a prescription. Try planning to deal with the sewage amount and calculate and obtain 0.25% solution, handling capacity is 2.5-3.2kg/h.
