Description
Technical field
The present invention relates to the recovery and reuse technology of waste material in string rug production, in particular to a kind of PVC mixture mistakes
The method and device that filter residue recycles.
Background technique
String rug is commonly called as " square carpet " also known as Split carpet.This carpet is readily transported, mats formation, arranges and tears open
It is office blanket preferred product except replacement is convenient.The structure of string rug is carried on the back again by the carpet surface of upper surface and at following bottom
It is combined into, carpet surface and bottom back are bonded together.Wherein carpet surface is that tufting base blanket is made by tufting with non-woven fabrics, then in tufting base
EVA latex is coated in the bottom surface of blanket, and tufting precoating carpet surface is made by baking process.Bottom back be usually the bottom PVC backing material, mainly by
Calcium powder (CaCO3) is commonly called as the PVC mixture that mountain flour, polyvinyl chloride (PVC), DINP or DOP oil etc. stir into paste, and PVC is mixed
Upper and lower two surface that material is coated in glass fabric is closed, then compound with the back side of tufting precoating carpet surface, added by dedicated baking oven
Heat, plasticizing are bonded together bottom back with carpet surface, referred to as cover bottom.The embossing cooling and shaping of carpet that bottom has been plasticized will be covered again to feed
Dicer cuts into the string rug of plurality of specifications size.The processing line of the carpet surface of tufting precoating at present and the bottom of covering of bottom back process
Line has realized automatic assembly line, and production efficiency is relatively high.But in covering bottom processing line, there is a critically important link raw material
Supply, batching weighing including various raw materials, raw material feeding, stirring, output and storage of various raw materials etc. all also in than
More original supply state.And PVC mixture is added in stirred tank and is carried out sufficiently according to a certain percentage by 5 kinds or more raw materials
Stirring and obtain.In large and medium-sized carpet manufacture enterprise, the stirring former material doses of a stirred tank reaches as many as several tons, but
Discovery is since there are dead angle, disposable dosages excessively to concentrate in stirring, adds raw material for raw material in the use of PVC mixture
Often there is small part PVC mixture and there is the phenomenon that agglomeration, influence the quality of coating, make in the reasons such as the bad dispersibility of itself
The problems such as at string rug out-of-flatness, influences the normal operation for covering bottom processing line.There is imagination to be provided with band in accumulator thus
Stirred tank is come out to accumulator and first passes through filter pocket by the lautertuns of strainer, after filtering, arrives storage again after filtering off block-like PVC material
Material cylinder is for coating.And the filter residue of PVC mixture cannot cause to waste using having to abandon as waste material after filtering, and
Also pollute the environment.
Summary of the invention
The object of the present invention is to provide a kind of pair of PVC mixtures to cross the method and device that filter residue carries out recycling and reusing.
In order to reach above-mentioned requirements, it is to pass through that PVC mixture of the present invention, which crosses the method and device that filter residue is recycled,
What following technical scheme was realized: it is to be provided with the filtering with 30-60 mesh filter screen in accumulator below stirred tank discharge port
Slot is filtered so that the PVC mixture to get off from stirred tank discharge port covers bottom for carpet to accumulator again after filtering to remaining in
Online filtered PVC filter residue processing method: it is characterized in that 100 parts of PVC mixture is crossed filter residue and 10-15 parts by weight
DOP oil ratio, be placed in agitator, by agitator perpendicular to the straight stirring rod of horizontal plane and with straight stirring rod at
The oblique stirring rod of 10 ° of -30 ° of angles carries out three-dimensional stirring, and the surrounding in the straight stirring rod and oblique stirring rod is equipped with paddle
Piece, the revolving speed of stirring rod are 60-120 revs/min, and mixing time is 2-2.5 hours, are then mixed the PVC after stirring by screw pump
It closes material filtering Slag treatment material to be transmitted back in stirred tank, carries out mixing again together with other raw materials for being used to prepare PVC mixture and stir
PVC material is mixed, so that PVC mixture is re-used after crossing filter residue recovery processing.
The method and device of filter residue recycling is crossed according to the PVC mixture that above scheme designs, it is this using DOP oil
Plasticiser crosses filter residue with PVC mixture and be sufficiently stirred merging, and smashes the strip and block structure that PVC mixture crosses filter residue, makes
It becomes paste, then re-enters stirred tank and is stirred again together with the raw material for preparing PVC mixture and is mixed into PVC and newly mixes
Close material.This method can cross filter residue progress in-situ processing to the PVC mixture generated in production, production scene obtains timely benefit
With, and it is easy to operate.Both the quality that ensure that product, reduces costs, and has prevented pollution environment.

Specific embodiment
The invention will be further described in the following with reference to the drawings and specific embodiments.
Fig. 1 is the schematic diagram for the method and device that PVC mixture crosses filter residue recycling.As seen from the figure, it is to stir
It mixes and is provided with the lautertuns 4 with 30-60 mesh filter screen 3 in the accumulator 2 below kettle discharge port 1, so that under stirred tank discharge port 1
The PVC mixture 5 come arrives accumulator 2 for precoating again after filtering, and the place of filter residue 6 is crossed for the PVC mixture on strainer 3
Reason method: 100 parts of PVC mixture is crossed to the DOP oil 7(dioctyl phthalate of filter residue 6 and 10-15 parts by weight)
Ratio is placed in agitator 8, by being at included angle A perpendicular to the straight stirring rod 9 of horizontal plane in agitator 8 and with straight stirring rod 9
10 ° -30 ° of oblique stirring rod 10 carries out three-dimensional stirring, and the surrounding in the straight stirring rod 9 and oblique stirring rod 10 is equipped with paddle
The revolving speed of piece 11, straight stirring rod 9 and oblique stirring rod 10 is 60-120 revs/min, and mixing time is 2-2.5 hours, then by screw rod
Pump 12 and conveying pipeline 13 send back to the PVC mixture filtering Slag treatment material 14 after stirring in stirred tank 15 again, are used for other
The raw material for preparing PVC mixture 5 is stirred into PVC mixture 5 again together, so that after PVC mixture crosses the recovery processing of filter residue 6
It is re-used.The side that wherein DOP oil tank 16 places agitator 8 utilizes height fall by petroleum pipeline 17 and valve 18
DOP oil 7 is added in agitator 8.
