Technical Field

The invention belongs to the technical field of toluene extraction equipment, and particularly relates to a novel toluene extractor for microfiber base cloth.

Background

In the process of manufacturing the microfiber synthetic leather, microfiber base cloth is fed into a multi-groove dipping groove containing toluene, and low-density polyethylene (sea phase) in sea-island fibers is dissolved out through repeated soaking and rolling in each groove, which is a process of extracting the polyethylene from the toluene. Repeated rolling is required because of the long process time for the dissolution of polyethylene in toluene. The conventional toluene extractor, as shown in FIG. 1, employs three pairs of steel rolls with a diameter of 300MM, which are pressed above the liquid level, immersed below the liquid level, and then pressed and immersed again. Generally, 7 extractors are needed, the number of rolled steel rollers needs more than 20 pairs, the soaked toluene needs 12 cubic meters of toluene soaking amount, 12 cubic meters of fresh toluene supplement amount is needed in each hour, and the efficiency is low.

Disclosure of Invention

In order to solve the above problems, an object of the present invention is to provide a novel toluene extractor for microfiber base fabric, which achieves the effect that many devices are needed to achieve originally with a small number of devices, and improves the production efficiency.

In order to achieve the purpose, the following technical scheme is provided:

a novel toluene extractor for microfiber base cloth mainly comprises a groove body, an elastic frame, a large extrusion roller, a heating pipe and a small steel roller; the tank body is provided with a tank body inlet and a tank body outlet, and the tank body is internally provided with an extrusion device which comprises a large extrusion roller, a small steel roller and a tightening frame; the periphery of the large extrusion roller is provided with a plurality of small steel rollers to form a structure for simultaneously extruding the large extrusion roller and the small steel rollers, the surface of the large extrusion roller is provided with a slot, and the extruded PE solution can be temporarily stored and discharged through the slot; the microfiber base cloth to be treated passes through the inlet of the tank body, the small steel roller, the large extrusion roller and the elastic frame to be connected to the outlet of the tank body.

Furthermore, the lower part of the groove body is provided with a heating pipe which is used for heating the toluene to boil the toluene.

Furthermore, a toluene inlet and a toluene outlet are arranged on the outer side of the groove body.

Furthermore, the toluene inlet and the toluene outlet are higher than the large squeeze roller, so that the soaking liquid level of the toluene can submerge the large squeeze roller after the toluene is added into the groove body, and the exchange effect of the PE solution is better.

The superfine base fabric to be treated enters from the inlet of the tank body, is extruded step by step through the small steel roller on the periphery of the large extrusion roller, enters the next-stage repeated cycle after passing through the elastic frame, finally goes out from the outlet of the tank body, the methylbenzene enters through the methylbenzene inlet and is discharged through the methylbenzene outlet, the soaking liquid level reached by the amount of the placed methylbenzene can submerge the large extrusion roller, and in the extrusion process, the heating pipe at the bottom of the tank body heats the methylbenzene, so that the methylbenzene in the tank body boils, and the pressurizing exchange effect is enhanced.

Compared with the prior art, the invention has the beneficial effects that:

1) the invention can obtain good drawing effect by continuous repeated extrusion of the large extrusion roller and the small steel roller and frequent impact extrusion.

2) The invention improves the efficiency, reduces the toluene consumption and saves the cost by continuous step-by-step extrusion.

3) The large extrusion roller is provided with the slots, so that the extruded PE solution can be temporarily stored, and the PE solution is convenient to discharge.
