[0002] Dyeing and finishing liquid is a general term for various chemical solutions used in the dyeing and finishing process of textiles. The composition and properties of dyeing and finishing liquid may vary depending on the specific dyeing and finishing process and requirements. Common components include dyes, auxiliaries (such as leveling agents, fixing agents, softening agents, etc.), acids, bases, salts, etc., which are used to achieve the desired color, hand, functionality (such as water resistance, wrinkle resistance, etc.) of the textile, and to improve the quality and performance of the textile. Different types of dyeing and finishing liquid are suitable for different fiber materials (such as cotton, hemp, silk, wool, chemical fiber, etc.) and dyeing and finishing processes (such as dyeing, printing, finishing, etc.), and in use, the dyeing and finishing liquid recovery device is usually applied to the following technologies:

[0009] However, the above-mentioned recovery method has poor filtering effect, and during the filtering process, impurities cannot be effectively collected and stored, and the equipment will soon be blocked due to impurity accumulation, so that continuous filtering is not possible, resulting in a decrease in filtering efficiency, frequent shutdown for cleaning, a reduction in the effective operation time of the equipment, and an increase in cleaning and maintenance costs.

[0010] In view of the existing structure and deficiencies, a dyeing and finishing dyeing and finishing liquid recovery device is provided. SUMMARY

[0014] The recovery tank is provided with a filtering mechanism;

[0015] The filtering mechanism includes an inner plate fixedly installed in the recovery tank, and an inner strip symmetrically fixedly installed in the inner wall of the inner plate with the midpoint as the axis of symmetry.

[0020] Preferably, a slot is formed in the inner plate of the filter screen frame, a limiting plate is inserted into the slot, and side blocks are symmetrically fixedly installed on the side wall of the limiting plate with the midpoint as the axis of symmetry.

[0021] Preferably, a second spring is fixedly installed at the lower end of each of the two side blocks, and one end of each of the two second springs away from the two side blocks is fixedly connected with the filter screen frame.

[0022] Preferably, a vertical strip is fixedly installed at the lower end of the filter screen frame, two groups of positioning rods are symmetrically fixedly installed on the side wall of the vertical strip with the midpoint as the axis of symmetry, and limiting grooves are formed in the two groups of positioning rods.

[0023] Preferably, a collecting box is inserted into each of the two groups of positioning rods, two groups of insertion holes are formed in the two collecting boxes, the two groups of positioning rods are respectively inserted into the two groups of insertion holes, and second filter screens are fixedly installed on the opposite ends of the two collecting boxes.

[0024] Preferably, a sliding column is slidably arranged inside the circular hole, an upper end of the sliding column is fixedly provided with a fixed disc, a lower end of the fixed disc is fixedly provided with a third spring, and an end of the third spring away from the fixed disc is fixedly arranged on the shunt strip.

[0025] Compared with the prior art, the present application has the following beneficial effects:

[0026] In the present application, the impurities generated during the filtering process can be pre-stored in the collecting box, so that the device can continuously filter the dyeing and finishing liquid, the cleaning cycle is prolonged, and the recovery efficiency is improved.

[0027] In the present application, when impurities are generated during filtering, part of the impurities will remain on the first filter screen, and the other part will flow into the collecting box under the flow of the dyeing and finishing liquid. The part of the impurities remaining on the first filter screen will also fall into the collecting box under the repeated flow of the dyeing and finishing liquid, completing the collection. This prevents the device from being easily blocked during use, and thus the filtering and recovery effect of the device can be maintained.

[0028] In the present application, the second spring is stretched under the movement of the limiting plate, and then the two collecting boxes are inserted on the two positioning rods. Then the limiting plate is loosened, and the second spring drives the limiting plate to reset and insert into the limiting slot, completing the limiting of the collecting box. Then the positioning holes on the filter screen frame are inserted on the four positioning columns, and then the box cover is clamped on the recycling box to complete the installation of the device. This makes the overall installation and disassembly of the device more convenient during use.

[0029] In the present application, the filter screen frame is moved downward on the positioning column under the slight vibration of the shunt strip when the dyeing and finishing liquid impacts on the shunt strip. At this time, the filter screen frame exerts a squeezing force on the four sliding rings, which drives the four first springs to compress and generate elastic force. This makes the filter screen frame maintain slight vibration when the dyeing and finishing liquid is injected, which helps to shake the impurities filtered out, so that they are not easily adhered to the device, further reducing the risk of blockage during filtering, improving the filtering efficiency and continuity.
