Abstract
The invention relates to a pre-condensing kettle which comprises a sealed tank, wherein a coiler is wound on the outer side of the lower part of the sealed tank, circulating oil is arranged in the coiler, one end of the coiler is provided with an oil inlet, the other end of the coiler is provided with an oil return hole, a feeding hole is formed in the side wall of the sealed tank, a discharging hole is formed in the bottom of the sealed tank, a gas-phase pipe is arranged at the top of the sealed tank, a stirring shaft and blades arranged on the stirring shaft are arranged inside the sealed chamber, an annular overflow channel is arranged in the inner wall of the sealed tank along the annular direction, an opening of the overflow channel faces upwards, and the overflow channel is communicated with the feeding hole. According to the pre-condensing kettle, the overflow channel is additionally provided, when materials enter the sealed tank, the materials fall along the tank wall of the sealed tank in a dispersing manner, and thus partial oligomers are separated during feeding, the efficiency of vacuum-pumping the oligomers is greatly increased, the pre-condensing time is shortened, and the work efficiency is increased.
Description
Technical field
The present invention relates to the production equipment technical field of polyester, refer to a kind of preshrunk still especially.
Background technology
The preshrunk still is one of capital equipment required in the production of polyester, and it mainly acts on is to adopt the mode that vacuumizes, and extracts the oligomer in the material out.Its structure generally includes a hermetically sealed can, the bottom outside disc winding of hermetically sealed can is equipped with coil pipe, recycle oil is set in the coil pipe, one end of coil pipe is oil-in, the other end of coil pipe is oil return opening, is provided with charging aperture in the sidewall of hermetically sealed can, and the bottom of hermetically sealed can is provided with discharging opening, the top of hermetically sealed can is provided with the gas phase pipe, and the inside of hermetically sealed can is provided with shaft and is arranged on blade on the shaft.During work, material enters in the hermetically sealed can from charging aperture, and shaft begins to stir, and logical recycle oil heats hermetically sealed can in the coil pipe, and the gas phase pipe begins to vacuumize, thereby extracts the oligomer in the material out.Its shortcoming is: when material enters hermetically sealed can from charging aperture, material can only enter the hermetically sealed can from a side of hermetically sealed can, and be deposited in a side of hermetically sealed can, must the oligomer in the material fully taken away, operating efficiency be lower.
Summary of the invention
Technical problem to be solved by this invention is: provide a kind of material can enter the preshrunk still of hermetically sealed can dispersedly.
For addressing the above problem, the technical solution used in the present invention is: a kind of preshrunk still, comprise a hermetically sealed can, the bottom outside disc winding of hermetically sealed can is equipped with coil pipe, recycle oil is set in the coil pipe, one end of coil pipe is oil-in, the other end of coil pipe is oil return opening, be provided with charging aperture in the sidewall of hermetically sealed can, the bottom of hermetically sealed can is provided with discharging opening, and the top of hermetically sealed can is provided with the gas phase pipe, the inside of hermetically sealed can is provided with shaft and is arranged on blade on the shaft, in the inwall of described hermetically sealed can along be arranged circumferentially the annular overflow launder, the opening of overflow launder up, overflow launder is connected with charging aperture.
Described overflow launder is L type structure, is provided with feed pipe in the hermetically sealed can, and an end of feed pipe is charging aperture, and the other end of feed pipe is connected with the bottom of overflow launder.
The oil return opening of described coil pipe is positioned at the top of oil-in.
The invention has the beneficial effects as follows: above-mentioned preshrunk still, it adopts and installs overflow launder additional, material is when entering hermetically sealed can, material is dispersed and falls along the tank skin of hermetically sealed can, thereby when charging, just realized the separation of part oligomer, improve the efficient that oligomer is taken away by vacuum greatly, shortened the preshrunk time, improved operating efficiency.
Description of drawings
Fig. 1 is structural representation of the present invention;
Among the figure: 1, hermetically sealed can, 2, coil pipe, 3, oil-in, 4, oil return opening, 5, charging aperture, 6, discharging opening, 7, the gas phase pipe, 8, shaft, 9, blade, 10, overflow launder, 11, feed pipe.
The specific embodiment
Below by specific embodiment a kind of preshrunk still of the present invention is described in further detail.
As shown in Figure 1, a kind of preshrunk still, comprise a hermetically sealed can 1, the bottom outside disc winding of hermetically sealed can 1 is equipped with coil pipe 2, in the coil pipe 2 recycle oil is set, one end of coil pipe 2 is oil-in 3, the other end of coil pipe 2 is oil return opening 4, and the oil return opening 4 of described coil pipe 2 is positioned at the top of oil-in 3, is provided with charging aperture 5 in the sidewall of hermetically sealed can 1, the bottom of hermetically sealed can 1 is provided with discharging opening 6, the top of hermetically sealed can 1 is provided with gas phase pipe 7, and the inside of hermetically sealed can 1 is provided with shaft 8 and is arranged on blade 9 on the shaft 8, in the inwall of described hermetically sealed can 1 along the overflow launder 10 that is arranged circumferentially annular, the opening of overflow launder 10 up, overflow launder 10 is connected with charging aperture 5.Described overflow launder 10 is L type structure, is provided with feed pipe 11 in the hermetically sealed can 1, and an end of feed pipe 11 is charging aperture 5, and the other end of feed pipe 11 is connected with the bottom of overflow launder 10.
Above-mentioned preshrunk still, it adopts and installs overflow launder 10 additional, material is when entering hermetically sealed can 1, and material enters from charging aperture 5, enters in the overflow launder 10 along feed pipe 11 then, and fill with whole overflow launder 10 gradually, final material is dispersed and falls along the tank skin of hermetically sealed can 1, thereby has just realized the separation of part oligomer when charging, has improved the efficient that oligomer is taken away by vacuum greatly, shorten the preshrunk time, improved operating efficiency.
The above embodiments are principle and the effect thereof of illustrative the invention only, and the embodiment of part utilization, but not is used for restriction the present invention; Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the invention design, can also make some distortion and improvement, these all belong to protection scope of the present invention.
