Abstract
The invention discloses a feeding system for polyester production, which comprises a feeding hopper, a conveyer, a conveying pipeline, a ration bin, a rotation blanking valve, a weighing device, and a slurry preparation tank, wherein raw materials are conveyed by the conveyer through the feeding hopper, enter the ration bin through the conveying pipeline, and enter the slurry preparation tank via the weighing device through the rotation blanking valve in the ration bin; and a vibration sieve is arranged between the conveying pipeline and the ration bin. The feeding system can separate sundries from the raw materials with the vibration sieve; the purity of the raw materials is ensured; therefore, the esterification reaction is performed normally. The feeding system has the functions of reducing the waste of the raw materials and the environmental pollution, and ensuring the product quality.
Description
Technical field
The present invention relates to the production of polyester field, relate in particular to feed system used in a kind of polyester production process.
Background technology
Source material delivery system is important part in the polyester production system.In existing source material delivery system, the raw material that provides, PTA for example, by artificial unpacking blanking, drop into hopper, be delivered to a day feed bin through three grades of chain scraper conveyors, PTA enters in the slurry preparation through rotating blanking valve, PTA scale in the day feed bin, be configured to qualified slurry, be delivered to reaction kettle of the esterification through screw pump and carry out esterification.But, because raw material PTA is packed Manual material feeding, often can be with in a large amount of fag ends, blade, the Nylon Bag fragment input coefficient, bulk foreign material in the hopper in the raw material, in process of production can stuck rotating blanking valve, cause compounding system to stop, a large amount of PTA dust can be revealed in the process of carrying out stuck processing, cause wastage of material and site environment to pollute; The fritter foreign material can enter the slurry configuration-system and stop up the PTA meausring apparatus, cause the weigh deviation, and then affect the mol ratio of whole slurry configuration, affect esterification and product index.And little fragment infiltrates in slurry through causing on-line densimeter and flowmeter indication deviation in the screw pump course of conveying, and then affects esterification liquid level and density, finally affects esterification and product quality.
Summary of the invention
For above-mentioned problems of the prior art, the object of the present invention is to provide a kind of feed system for production of polyester, it can be separated the foreign material in the raw material automatically, reaches the purification raw material, guarantees to produce smoothly the effect of Improving The Quality of Products.
To achieve these goals, the technical solution used in the present invention is as follows:
A kind of feed system for production of polyester, comprise cast hopper, conveyer and conveyance conduit, day feed bin, rotating blanking valve, meausring apparatus, slurry preparation, raw material is carried by conveyer through cast hopper, enter a day feed bin through conveyance conduit, the interior raw material of day feed bin enters slurry preparation through rotating blanking valve by meausring apparatus, and the slurry that finally configures is delivered to reaction kettle of the esterification by screw pump and carries out esterification.It is characterized in that, between described conveyance conduit and described day feed bin, be provided with vibratory sieve.
Further, described shaker screen is 2 orders.
Further, described vibratory sieve place is provided with video frequency pick-up head.
Further, described conveyer is three grades of chain scraper conveyors.
Description of drawings
Fig. 1 is the schematic diagram of the feed system for production of polyester of the present invention.
The specific embodiment
In order to make purpose of the present invention, technical scheme and advantage clearer, below in conjunction with accompanying drawing, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, is not intended to limit the present invention.
Present embodiment provides a kind of feed system for production of polyester, as shown in Figure 1, this feed system comprises cast hopper, conveyer 1 and conveyance conduit, vibratory sieve 2, day feed bin 4, rotating blanking valve 5, meausring apparatus 6, slurry preparation 7, the PTA raw material is carried by conveyer 1 through cast hopper, through conveyance conduit, cross vibratory sieve 2 and enter day feed bin 4, PTA raw material in day feed bin 4 enters slurry preparation 7 through rotating blanking valve 5 by meausring apparatus 6, and the slurry that configures is delivered to the pet reaction still by screw pump.
In process of production, the PTA raw material drops into cast hopper through artificial unpacking, be delivered to vibratory sieve 2 through three grades of chain scraper conveyors 1 via conveyance conduit, through vibratory sieve 2 the frequent foreign material that occur such as fag end, blade, Nylon Bag etc. in the PTA raw material are separated out the PTA raw material input day feed bin 4 after processing through vibratory sieve 2.PTA raw material in day feed bin 4 is through rotating blanking valve 5 and enter at last slurry preparation 7 through weighing device 6 and carry out slurry preparation and by screw pump accepted stock is sent into the pet reaction still.
Increased the feed system that is used for production of polyester of vibratory sieve 2 can be effectively with the foreign material filtering of PTA raw material.After the feed system of using after improving, the situation of stuck stoppage in transit does not appear in slurry preparation system again, and the PTA accuracy of weighing system is improved, and has guaranteed that mol ratio is stable.Online densitometer and flowmeter do not occur stopping up the vacation indication phenomenon that causes because of foreign material more yet.The purity of PTA raw material is promoted and has been guaranteed product quality, has solved simultaneously the problems such as wastage of material, environmental pollution.
With the foreign material filtering in the PTA raw material, the filter screen of described vibratory sieve 2 can be the 1-3 order for effectively, is 2 orders in a preferred embodiment of the present invention.
In another preferred embodiment of the present invention, 2 places are provided with video frequency pick-up head 3 at vibratory sieve, can monitor at any time the raw material distributing procedure at Central Control Room, break down and can in time keep in repair.
In addition, in an embodiment of the present invention, described conveyer 1 is three grades of chain scraper conveyors.
The above embodiment has only expressed embodiments of the present invention, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to claim of the present invention.Should be pointed out that for the person of ordinary skill of the art without departing from the inventive concept of the premise, can also make some distortion and improvement, these all belong to protection scope of the present invention.Therefore, the protection domain of patent of the present invention should be as the criterion with claims.
