Description
Technical field
The utility model relates to the PTA filtration system of a kind of not easily batch mixing and blocking.
Background technology
Need to use filter-press in PTA production process, and filter-press needs to use a large amount of alkali lye when alkali cleaning, then usually having alkali during alkali cleaning along with feeding machine, screw rod, drying machine enters into equipment, and these alkali can finally enter into product and go, thus have impact on the quality of product; The head tank very easily pressure release when returning charge of filter-press, causes container inner wall to form block material simultaneously, makes pipeline blockage cause stopping production completely, have impact on normally carrying out of production.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, provides one that alkali can be prevented to be mixed into product, ensure that product quality, prevent pipeline blockage, ensures the PTA filtration system of producing not easily batch mixing and the blocking normally carried out.
The purpose of this utility model is achieved in that
The PTA filtration system of the utility model not easily batch mixing and blocking, comprise filter-press, the inlet of described filter-press is connected with alkali liquor pipe, this alkali liquor pipe is connected to a nitrogen tube, the discharging opening of described filter-press is connected with feeding machine, filter-press also has exhaust outlet, be connected with screw rod on rear side of described feeding machine, the rear side of described screw rod is connected with drying machine, the downward perforate in both sides of described feeding machine and screw rod outer casing bottom is also provided with drain valve, described head tank has additional a circulation line, this circulation line is provided with surge tank, pump and blend tank, described blend tank is back in head tank, an elimination Brine Pipe is connected between described blend tank and head tank.
Compared with prior art, the beneficial effects of the utility model are:
The PTA filtration system of this not easily batch mixing and blocking by passing into nitrogen in the alkali liquor pipe of filter-press, the probability that alkali lye enters equipment on rear side of filter-press can be reduced, simultaneously feeding machine and screw rod outer casing bottom two STH holes and be provided with drain valve, can effectively discharge the alkali lye entered in feeding machine and screw rod, thus prevent from alkali from entering into product going, and then ensure that the quality of product; On the head tank of filter-press, set up a circulation line simultaneously, this circulation line is provided with surge tank, pump and blend tank, blend tank is back in head tank, and between blend tank and head tank, connect one eradicated Brine Pipe, can lower the temperature to slurry and reduce concentration after passing into demineralized water, form block material in a reservoir after preventing slurry pressure release, thus prevent pipeline blockage, and then ensure that normally carrying out of production.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model not easily PTA filtration system of batch mixing and blocking.
Wherein: filter-press 1, alkali liquor pipe 1.1, nitrogen tube 1.2, exhaust outlet 1.3, feeding machine 2, screw rod 3, drying machine 4, drain valve 5, head tank 6, surge tank 7, pump 8, blend tank 9, desalination water pipe 10.
Detailed description of the invention
See Fig. 1, the utility model relates to the PTA filtration system of a kind of not easily batch mixing and blocking, comprise filter-press 1, the inlet of described filter-press 1 is connected with alkali liquor pipe 1.1, this alkali liquor pipe 1.1 is connected to a nitrogen tube 1.2, the discharging opening of described filter-press 1 is connected with feeding machine 2, filter-press 1 also has exhaust outlet 1.3 for emission gases, be connected with screw rod 3 on rear side of described feeding machine 2, the rear side of described screw rod 3 is connected with drying machine 4, the downward perforate in both sides of described feeding machine 2 and screw rod 3 outer casing bottom is also provided with drain valve 5 for discharging alkali lye, the charging aperture of described filter-press 1 is connected with head tank 6 by pipeline, described head tank 6 has additional a circulation line, this circulation line is provided with surge tank 7, pump 8 and blend tank 9, described blend tank 9 is back in head tank 6, an elimination Brine Pipe 10 is connected to for passing into demineralized water between described blend tank 9 and head tank 6.
The PTA filtration system of this not easily batch mixing and blocking by passing into nitrogen in the alkali liquor pipe 1.1 of filter-press 1, the probability that alkali lye enters equipment on rear side of filter-press 1 can be reduced, simultaneously feeding machine 2 and screw rod 3 outer casing bottom two STH holes and be provided with drain valve 5, effectively can discharge the alkali lye entered in feeding machine 2 and screw rod 3, thus prevent from alkali from entering into product going, and then ensure that the quality of product; On the head tank 6 of filter-press 1, set up a circulation line simultaneously, this circulation line is provided with surge tank 7, pump 8 and blend tank 9, blend tank 9 is back in head tank 6, and between blend tank 9 and head tank 6, connect one eradicated Brine Pipe 10, can lower the temperature to slurry and reduce concentration after passing into demineralized water, form block material in a reservoir after preventing slurry pressure release, thus prevent pipeline blockage, and then ensure that normally carrying out of production.
