Furthermore, the valve comprises a valve plate and a compression spring, a material passing hole is formed in the circumferential surface of one end, close to the feeding connecting pipe, of the material pipe, and the material pipe is pressed against the valve plate to enable the material pipe to be communicated with the feeding connecting pipe.
Furthermore, the secondary recycling treatment device for the polyester textiles further comprises a distilled water tank, an interlayer is arranged in the sealing cylinder and connected with the distilled water tank, a plurality of cleaning holes are formed in the inner wall of one section of the sealing cylinder, which is close to the filter cylinder, and each cleaning hole is communicated with the interlayer.
Furthermore, a slag discharging connecting pipe communicated with the filter residue cavity is arranged on the filter box.
Further, dacron textile secondary retrieval and utilization processing apparatus still includes a filter residue storage tank, arrange the sediment takeover and link to each other with the filter residue storage tank.
Furthermore, a water inlet connecting pipe communicated with the interlayer is arranged on the filter box, and the water inlet connecting pipe is connected with the distilled water tank.
Further, a plugging sleeve positioned in the filtrate cavity is fixedly arranged on the piston, and the plugging sleeve can block an inlet of the discharge connecting pipe.
Further, the outer diameter of the screw is matched with the inner diameter of the filter cylinder.
The working principle is as follows: the alcoholysis reaction kettle decomposes a multi-fiber mixture containing polyester fibers or a polyester fiber cloth containing impurities to form liquid slurry containing the polyester fibers, and insoluble substances in the liquid slurry are extracted through a filter, specifically: negative pressure acts in the filtrate cavity, when the filter hole on the filter drum is good in communication, the return spring drives the piston to be positioned in the middle of the filter box, at the moment, the material pipe is inserted into the material inlet connecting pipe, the valve is in an open state, liquid slurry to be filtered in the alcoholysis reaction kettle is pumped into the filter drum, the liquid slurry enters the filtrate cavity after being filtered by the filter drum, then the liquid slurry enters the material storage tank through the material outlet connecting pipe, the screw preliminarily cleans the inner wall of the filter drum, because the aperture of the material inlet connecting pipe is far larger than that of the water inlet pipe, when the filter residue storage in the filter drum and the material pipe is small, distilled water is hardly discharged from the cleaning hole, because the rotation direction of the screw can drive the filter residue to tend to the material pipe, the filter residue in the material pipe is continuously accumulated until the circulation of the liquid to be filtered in the material pipe is influenced, at the moment, the distilled water can enter the interior of the filter drum through the distilled water tank, the interlayer and the cleaning hole, the screw continuously sends the distilled water into the material inlet pipe, rinsing the filter residue in the material pipe to wash out soluble substances remained on the filter residue and send the filter residue into the filtrate cavity; in the rinsing process of filter residues, part of liquid to be filtered still has a feeding connecting pipe to enter the feeding pipe, in addition, the piston can move towards the direction of the filtrate cavity due to the increase of negative pressure in the filtrate cavity in the process, the filter cylinder is gradually wrapped by the sealing cylinder, part of cleaning holes are positioned on the outer side of the filter cylinder, and the distilled water discharged from the cleaning holes can reversely wash the filter cylinder. Each state is being strained a section of thick bamboo and is being slightly blockked up promptly and exist simultaneously, and pile up more, and strain a section of thick bamboo and most parcel by a section of thick bamboo of sealing in the charge pipe, and at this moment, the charge pipe breaks away from the pan feeding takeover, and the valve in the pan feeding takeover is closed, treats that filtering liquid can't follow the pan feeding takeover and discharges, and the continuation rotation of screw rod can make the interior filter residue of charge pipe crowded filter residue intracavity into, of course, along with the filter residue gets into the filter residue chamber still some distilled water, the filter residue that contains certain moisture can be taken over by the sediment of filter residue chamber bottom and gets into the filter residue storage tank.
At the moment when the filter residue is discharged, because the material pipe is not blocked by the filter residue any more, the piston is reset under the action of the reset spring, the material pipe is communicated with the feeding connecting pipe again, the valve is also opened, and the filter cartridge is used for filtering the liquid to be filtered again in a better state; this is repeated. The solid material content in the filter residue cavity is high, and the negative pressure in the filtrate cavity can not cause the backflow of the material in the filter residue cavity in a short time when the material pipe is not connected with the feeding connection pipe of the barrel.
Due to the existence of the plugging sleeve, in the process that the material pipe is separated from the feeding connecting pipe, the plugging sleeve can completely plug or partially plug the inlet of the discharging connecting pipe, on one hand, the situation that the negative pressure in the material pipe is too high in the process can be avoided, filter residues can be discharged more smoothly due to small negative pressure outside the filter cylinder, the slag discharging time can be prolonged, a large stroke can be ensured when the piston is reset, and the filter area of the filter cylinder participating in next filtering is large.
The resetting of the piston relies to a large extent on a return spring.
The cleaning hole is mainly used for discharging distilled water, and reverse cleaning of the filter cylinder is only effective when the filter cylinder is larger in wrapped area by the sealed pipe and more in filter residue accumulation in the material pipe.
When the filter cartridge is seriously blocked and the filter residue in the material pipe is accumulated more, the filter cartridge can be gradually inserted into the seal cartridge under the action of negative pressure, the filter area on the filter cartridge is reduced along with the insertion of the filter cartridge, the negative pressure in the filter cavity is further increased, and the piston can be driven to close the discharge connecting pipe.
The obtained mixture of the polyester fiber monomer, distilled water, glycol and the like is decolored, filtered, crystallized and dried to obtain a crystal which can be used for polyester fiber spinning again.
According to the scheme, the filter filtration, the slag discharge, the rinsing of filter residues and the cleaning of the filter cartridge (the slag discharge treatment of the screw and the reverse washing of distilled water) can be automatically completed, so that the filter filtration treatment can be continuously carried out on the terylene alcoholysis mixture on line, and the production efficiency and the yield are greatly improved.
