Description
Technical field
The utility model relates to a kind of polyester pulp preparing tank, belongs to industrial chemicals equipment technology field.
Background technology
Polyester pulp is formed according to certain molar ratio by PTA (white solid powder) and EG (colourless transparent liquid).Slurry preparation carries out continuously and finally forms the unit for uniform suspension of PTA, EG.In slurry preparation process, due to the stirring action of agitator and the high temperature of generation thereof, produce a large amount of EG steam in preparing tank, EG steam can be discharged from tank deck vent line by entrainment portions PTA powder.Long term, PTA, EG dope constantly can adhere at vent line inwall, and blocking pipeline even causes pressure in tank to raise, and PTA cannot normally add, and impact is produced and normally carried out.So polyester pulp preparing tank vent line needs regular dismounting to clean.Because vent line is positioned at high-altitude, tediously long (cumulative length about 6 meters), irregular, dismounting needs lifting, so clean-drain pipeline at substantial manpower and materials, and operator's work risk is high, purge contaminated environment.
Utility model content
Technical problem to be solved in the utility model is the above-mentioned defect for prior art, provides kind of a polyester pulp preparing tank, and the utility model object is to make vent line without the need to disassembly, cleaning, reduces manpower and materials loss, reduces operational hazards, protection of the environment.
To achieve these goals, the utility model provides a kind of polyester pulp preparing tank, comprise a preparing tank body, described preparing tank body is provided with a PTA feeding line, an EG charging Trunk Line, an EG feed-inputing branched pipe line, a vent line, described EG charging Trunk Line is connected in described vent line by described EG feed-inputing branched pipe line, the terminal part of described EG feed-inputing branched pipe line stretches into described vent line, described terminal part dish becomes a non-close circular, described terminal part blind plate welded closure, is along the circumferential direction provided with multiple circular hole at terminal part.
Described polyester pulp preparing tank, the described PTA feeding line both sides that are arranged at described preparing tank body central axis corresponding to described vent line.
Described polyester pulp preparing tank, also comprises a main control valve, and described main control valve is arranged on described EG charging Trunk Line.
Described polyester pulp preparing tank, described EG feed-inputing branched pipe wire bonding is connected on described EG charging Trunk Line, and the pad of described EG feed-inputing branched pipe line and described EG charging Trunk Line is positioned at inside master control valve 7.
Described polyester pulp preparing tank, described EG feed-inputing branched pipe line is provided with one point of control valve.
Described polyester pulp preparing tank, described terminal part is along the circumferential direction drilled with 10 equally distributed circular holes.
Beneficial functional of the present utility model is:
Namely this preparing tank vent line in slurry preparation process is fully cleaned, and vent line is without the need to dismounting, and labour intensity reduces greatly, and environmental pollution is avoided.
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail, but not as to restriction of the present utility model.

Detailed description of the invention
Below in conjunction with accompanying drawing, structural principle of the present utility model and operation principle are described in detail:
See Fig. 1, Fig. 1 is the structural representation of the utility model one embodiment, polyester pulp preparing tank of the present utility model, just fully cleaned for vent line in slurry preparation process, vent line is without the need to dismounting, labour intensity reduces greatly, environmental pollution is avoided, the polyester pulp preparing tank that the utility model provides comprises a preparing tank body 1, preparing tank body 1 is provided with a PTA feeding line 2, one EG charging Trunk Line 6, one EG feed-inputing branched pipe line, one vent line 3, EG charging Trunk Line 6 is connected in vent line 3 by EG feed-inputing branched pipe line 4, namely an EG feed-inputing branched pipe line 4 is drawn from EG charging Trunk Line 6, EG charging Trunk Line 6 is welded with master control valve 7, EG feed-inputing branched pipe line and EG charging Trunk Line 6 are welded to connect, EG feed-inputing branched pipe line 4 is positioned at inside master control valve 7 with the pad of EG charging Trunk Line 5, EG feed-inputing branched pipe line 4 is provided with one point of control valve 5, the terminal part of EG feed-inputing branched pipe line 4 stretches into vent line 3, see such as Fig. 2, for A-A direction partial schematic diagram, terminal part dish becomes a non-close circular, terminal part blind plate 9 welded closure that non-close is circular, the circular terminal part of non-close is along the circumferential direction drilled with 10 equally distributed circular holes 8.The PTA feeding line both sides that are arranged at preparing tank body central axis corresponding to vent line 3.
For further describing the course of work of this slurry preparation, its operating procedure is as follows:
(1) slurry preparation starts, and opens master control valve 7, EG charging Trunk Line 6 and starts charging.
(2) PTA feeding line 2 starts charging.
(3) open sub-control valve 5, EG feed-inputing branched pipe line 4 and start charging, EG is spouting from 10 circular holes 8, and vent line 3 is fully cleaned.
(4) slurry preparation terminates, and stops PTA feeding line 2 charging.
(5) close sub-control valve 5, stop the charging of EG feed-inputing branched pipe line 4.
(6) close master control valve 7, stop the charging of EG charging Trunk Line 6, slurry preparation stops.
Certainly; the utility model also can have other various embodiments; when not deviating from the utility model spirit and essence thereof; those of ordinary skill in the art are when making various corresponding change and distortion according to the utility model, but these change accordingly and are out of shape the protection domain that all should belong to the claim appended by the utility model.
