[0006] The air inlet end of the air extraction pipe is connected to the upper part of the dyeing tank, and the air outlet end is connected to the gas treatment device. The air extractor is installed on the air extraction pipe.

[0007] The dyeing tank has a plurality of openings, and the inlet end and the outlet end of the circulation pipe are both located in the dyeing tank and below the lowest opening. The filter device and the pump are both installed on the circulation pipe.

[0008] By adopting the above technical scheme, the air extractor extracts harmful gases generated by the dyeing liquid loaded in the dyeing tank, and the harmful gases are introduced into the gas treatment device for environmental protection treatment. The pump extracts the dyeing liquid flow loaded in the dyeing tank through the filter device, the filter device filters out the lint and particulate matter in the dyeing liquid, and the filtered dyeing liquid returns to the dyeing tank. The above settings reduce the influence of lint and particulate matter in the dyeing liquid on the dyeing quality of the cloth, and reduce the pollution of harmful gases volatilized from the dyeing liquid to the air.

[0009] In one preferred scheme of the textile dyeing gas-liquid separation filter, the gas treatment device comprises a spray tower and a UV light degradation purifier, and the spray tower is connected to the air outlet end of the air extraction pipe. The UV light degradation purifier is connected to the spray tower.

[0010] By adopting the technical scheme, the spray tower can remove particles, dust, grease and other substances, and the UV light degradation purifier can purify malodorous gas.

DETAILED DESCRIPTION

[0034] The technical solutions in the embodiments will be described clearly and completely below with reference to the drawings. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the following embodiments, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0035] As Figure 1 A textile dyeing gas-liquid separation filter machine comprises a dyeing box 1, an air extraction pipe 2, an air extractor 3, a gas treatment device 4, a circulation pipe 5, a filtering device 6 and a pump 7.

[0036] One scheme of the gas treatment device 4 is a combination of a spray tower 401 and a UV light degradation purifier 402. The air inlet end of the air extraction pipe 2 is communicated with the top surface of the dyeing box 1, so as to collect the harmful gas volatilized from the dyeing liquid in the dyeing box 1.

[0037] The air extractor 3 can be a fan or other air extraction device. The air extractor 3 is installed in the air extraction pipe 2 and used to extract the harmful gas volatilized from the dyeing liquid in the dyeing box 1. The air outlet end of the air extraction pipe 2 is connected with the spray tower 401, and the spray tower 401 is connected with the UV light degradation purifier 402.

[0038] When the exhaust fan 3 is turned on, the gas generated by the dyeing liquid first enters the exhaust pipe 2, and then flows into the lower end of the spray tower 401. The spray tower 401 sprays water onto the incoming gas, removing particles, dust, grease, and other substances. The sprayed gas flows out from the top of the spray tower 401 and enters the UV photodegradation purifier 402 under the guidance of the pipe. The UV photodegradation purifier 402 uses a specially designed high-energy, high-ozone UV ultraviolet light beam to irradiate organic gases and oxygen molecules in the air, breaking the molecular bonds of organic gases and decomposing oxygen molecules in the air to produce free oxygen. The free oxygen and oxygen molecules combine to form ozone. The free pollutant molecules react with ozone to generate small-molecule harmless or low-harm compounds, such as CO2 and H2O, thereby achieving the effect of purifying the gas. The purification capacity can reach 99%. The UV photodegradation purifier 402 can be the UV photolysis purification equipment supplied by Beijing Huakang Zhongtian International Environmental Protection and Energy Saving Technology Co., Ltd., or the photodeodorization equipment produced by Hebei Guanglv Environmental Protection Equipment Co., Ltd. The gas treated by the UV photodegradation purifier 402 is discharged directly into the atmosphere through the pipe above the UV photodegradation purifier 402.

[0039] like Figure 2 The filter device 6 includes a frame 601 and a filter screen 602, with the filter screen 602 installed inside the frame 601. The frame 601 has an interface on both its upper and lower sides, which are connected to the circulation pipe 5. The filter screen 602 can be made of polypropylene, fiberglass, or stainless steel. These materials generally do not absorb the effective components of the dye liquor, allowing them to pass smoothly through the filter screen 602 without affecting the dyeing effect.

[0040] The dyeing box 1 has an opening on each of its left and right sides, such as... Figure 1 The left side is the feed inlet 101, such as Figure 3 The right side is the discharge port 102. The fabric to be dyed enters from the feed port 101 and flows out from the discharge port 102.

[0041] like Figure 4 Inside the dyeing box 1, there are rotating feed rollers 8, five tension rollers 9 and two discharge clamping rollers 10. Outside the dyeing box 1, there are also two drive clamping rollers 11. These rollers are parallel to each other.

[0042] The fabric is wound around the feed roller 8 and five tension rollers 9 in sequence, and passes through the gap between the two discharge clamping rollers 10 and the gap between the two drive clamping rollers 11 in sequence.

[0043] The feed roller 8 is flush with the feed inlet 101, allowing the fabric to enter the dyeing box 1 horizontally and reducing friction between the fabric and the feed inlet 101. The five tension rollers 9 are lower than the feed inlet 101 and the discharge outlet 102, allowing the dye liquor to submerge the five tension rollers 9 with the liquid level below the feed inlet 101 and the discharge outlet 102, thus soaking the fabric in the area of ​​the five tension rollers 9 for dyeing.

[0044] Two discharge pinch rollers 10 elastically abut each other to squeeze the dye on the cloth before the cloth flows out of the dyeing box 1.

[0045] Two cloth driving pinch rollers 11 elastically abut each other, and a rotating shaft of a motor 12 is fixed to one of the two cloth driving pinch rollers 11. When the motor 12 is started, the two cloth driving pinch rollers 11 rotate in opposite directions, so as to clamp and drive the cloth to move.

[0046] The upper section of the circulation pipe 5 penetrates into the dyeing box 1, and the inlet end thereof is located above the five tension rollers 9 but below the feeding port 101 and the discharging port 102, so as to be able to draw the dyeing liquid. The filtering device 6 and the pump 7 are installed outside the dyeing box 1.

[0047] The pump 7 is farther away from the inlet end of the circulation pipe 5 than the filtering device 6, so that the dyeing liquid can enter the pump 7 after being filtered, thereby reducing the accumulation of lint and particulate matters in the pump 7. The lower section of the circulation pipe 5 penetrates into the dyeing box 1 downward, and the outlet end thereof is located below the five tension rollers 9, so as to send the filtered dyeing liquid thereto. Through continuous circulation, the concentration of lint and particulate matters in the dyeing liquid is maintained at a low level, thereby reducing the risk of dyeing quality caused by lint and particulate matters.

[0048] Reference Figure 5 In addition, two groups of heating wires 13 are installed in the dyeing box 1, and are respectively installed on the two sides of the five tension rollers 9. The two groups of heating wires 13 are located below the feeding port 101 and the discharging port 102, and are used to heat the dyeing liquid in the dyeing box 1, so as to improve the dyeing efficiency of the cloth.

[0049] The textile dyeing gas-liquid separation filter machine of the above embodiment is provided with the gas treatment device 4 to collect and environmentally degrade the harmful gas generated by the dyeing liquid, thereby reducing the pollution to the air. The filtering device 6 is provided to filter the lint and particulate matters in the dyeing liquid, which is helpful to improve the dyeing quality of the cloth.

[0050] Although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments, or equivalently replace part of the technical features, as long as they are within the spirit and principles of the present application. Any modification, equivalent replacement, improvement, etc. made within the scope of the present application shall be included in the protection scope of the present application.
