embodiment 2:referring to Fig. 1, as a kind of improvement of the present utility model, in described plate and frame filter press, be provided with filter plate 3, between filter plate and filter plate, be provided with filter cloth 2.During cleaning, do not need to remove the filter cloth in plate and frame filter press, simple and convenient.All the other structures are identical with embodiment 1 with advantage.
embodiment 3:referring to Fig. 1, as a kind of improvement of the present utility model, described wash solution delivery pump 6 connects plate and frame filter press 1 by wash solution carrier pipe 7, wash solution by-pass valve control 8, press pump pipeline 11 mixed with cleaning solution, is also connected with press pump normal operation by-pass valve control 9 and press pump normal operation pipeline 10 on described press pump pipeline 11 mixed with cleaning solution.All the other structures are identical with embodiment 1 with advantage.
embodiment 4:referring to Fig. 1, as a kind of improvement of the present utility model, described plate and frame filter press is circumscribed with waste liquid conveying device, slurry conveying device and press water conveying device.Described waste liquid conveying device comprises that waste liquid arranges the outer discharge pipe 13 of by-pass valve control 12 and waste liquid outward; Described slurry conveying device comprises mud liquid inlet control valve door 14 and mud feed liquor carrier pipe 15; Described press water conveying device comprises press water water inlet control valve door 16 and press water conveyance conduit 17.All the other structures are identical with embodiment 1 with advantage.
Concrete cleaning method is as follows, referring to Fig. 1, a kind of method of online soaking and washing plate and frame filter press oil-containing filter cloth, concrete steps and requirement be, 1) the main cleaning fluid of filter cloth: wash solution 5 and press water, solution by Steam Heating to 40-50 ℃; Solution pool is configured to 6m
3, the actual 4m that uses
3.Owing to adopting Steam Heating, in pond, need to carry out interior preservative treatment.2) press water in press water conveyance conduit 17 carries out preliminary flushing to filter cloth 2 under press water water inlet control valve door 16 is controlled, and flushing water discharge pipe 13 outside waste liquid is arranged under the control of by-pass valve control 12 by waste liquid outward flows back to pre-concentration pond; 3) make a wash solution regulating reservoir 4, be used for, according to the number of the oil content of filter cloth 2, industrial detergent and water are mixed and made into the applicable wash solution of concentration 5; According to mud oil-containing difference and filter press service time, cleaning solution configuration proportion is controlled at 5-10g/L 4) a wash solution delivery pump 6 is installed, the wash solution of 4 li of wash solution regulating reservoirs 5 is passed through to wash solution carrier pipe 7, under controlling, wash solution liquid inlet control valve door 8 is transported to 2 li of the filter plate 3 of plate and frame filter press 1 and filter clothes, filter cloth 2 is soaked, make greasy dirt on filter cloth be washed solution and fully dissolve.In immersion process, filter press pressure is controlled at 0.1MPa left and right, soaks 30-60 minute.After soaking after a while, then waste liquid is arranged to by-pass valve control 12 outward and open, make waste liquid flow back to pre-concentration pond by the outer discharge pipe 13 of waste liquid.So repeatedly for several times, reach the effect of soaking and washing filter cloth greasy filth; 5) press water in final pressure water conveyance conduit 17 again rinses filter cloth 2 under press water water inlet control valve door 16 is controlled, flushing water discharge pipe 13 outside waste liquid is arranged under the control of by-pass valve control 12 by waste liquid outward flows back to pre-concentration pond, reaches the effect of rinsing filter cloth.
Practice shows, adopts this device effectively the greasy dirt on filter cloth for plate-frame type filter presses to be cleaned up.The time of soaking in wash solution according to the different wash solution concentration of how many adjustment of greasy dirt on filter cloth and filter cloth, after wash solution soaking and washing, with press water, rinse again, make filter cloth return to rapidly original function.After enforcement, not only save the expense of dismounting every day filter cloth, also reduced operating personnel's working strength, extended filter cloth service life, reached the object of cost efficiency, obtained numerous technical staff's approval.
Application example:
The mud that the turbid circulatory system of line produces after water treatment is produced in Mei Gang company hot rolling 1780, in sludge dewatering process, plate and frame filter press is dewatered to mud.Inevitable leakage of oil due to rolling line hydraulic system and plant equipment, and upkeep operation is changed oil in process and is caused oily leakage, Deng factors, make these waste oil flow into Whirlwind tank along iron sheet ditch, again by water pump lifting and through water treatment, along with waste water enters sludge treating system, finally under plate and frame filter press work, make oil, water, mud carry out separation.Because greasy dirt stickiness is larger, after the every task of plate and frame filter press, always there is greasy filth to be bonded on filter cloth, stop up filter cloth gap, affect filter effect, must clean up, otherwise board and frame machine cannot carry out sludge dewatering work next time.The method that past adopts is after utilizing press water to rinse filter cloth surface, then filter cloth is taken apart with industrial detergent and carried out greasy dirt washing.Like this, not only increase operating personnel's working strength, and in the disassembly process of filter cloth, easily caused the damage of filter cloth, affected the service life of filter cloth.We clean the method for plate and frame filter press oil-containing filter cloth through summing up to scene; and present situation is analyzed; propose that wash solution is directly injected to filter cloth filter cloth is carried out to online soaking and washing; when can effectively solve filter cloth cleaning performance, the damage to filter cloth in disassembly process of protection filter cloth.So technical staff has carried out autonomous Design, in conjunction with on-the-spot actual, invent this online soaking and washing plate and frame filter press system, cause is pressed for time, task is anxious, fund lacks, utilize existing press water and standby press pump and dosing pond and section of tubing, carry out oneself's processing, by press water pipeline and plate and frame filter press charging main pipeline are carried out to pipeline communication, standby press pump pipeline is transformed, and does not need to increase equipment.In cleaning solution concentration, be 7mg/L, 40 ℃ of temperature, soaked after 60 minutes, rinsed water outlet oil content <5mg/L with press water.The cleaning filter cloth time was reduced to 1 hour by 1 day.The method of this kind of online soaking and washing plate and frame filter press oil-containing filter cloth is easy to operate, convenient, just can make filter cloth clean effectively, has also reduced probability and hand labor intensity that filter cloth damages, has extended the filter cloth life-span, has reached the object of cost efficiency.
The utility model can also be combined to form new embodiment by least one and embodiment 1 in technical characterictic described in embodiment 2,3,4.
It should be noted that above-described embodiment is only preferred embodiment of the present utility model; be not used for limiting protection domain of the present utility model; being equal to replacement or substituting of having done on the basis of the above all belongs to protection domain of the present utility model, and protection domain of the present utility model is as the criterion with claims.
