Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments. In order to highlight the focus of the present invention, some conventional operations and devices, apparatuses, components are omitted or only briefly described.

As shown in fig. 1 to 3, a recycling device for cloth dyeing wastewater comprises a tank 100 and preferably further comprises a bracket. The can 100 is mounted on a bracket. The tank 100 is provided with an air inlet 101, an air outlet 102, a water inlet 103, a water outlet 104 and a sewage outlet 105. Preferably, the water inlet 103 is connected to the water outlet of the dyeing machine; the drain 104 is connected to the inlet of the dyeing machine. Preferably, a viewing window 107 is embedded in the sidewall of the can body 100. The condition of the brush and the filter screen inside the tank 100 and the condition of sludge accumulation at the sewage discharge port can be observed through the observation window 107.

A filter pipe 200 is vertically arranged in the tank body 100; the top end of the filter pipe 200 is communicated with the water inlet 103, and the bottom end of the filter pipe 200 is communicated with the sewage outlet 105. The drain opening 105 is detachably connected with a cover 300. Preferably, the drain 105 is threadedly coupled to the cover 300.

The outer wall of the filter pipe 200 is provided with at least two vertical transparent water outlet pipes 201, and the water outlet pipes 201 are communicated with the inside of the filter pipe 200. Preferably, as shown in fig. 3, the outer wall of the filter pipe 200 is provided with four vertical rows of outlet pipes 200. The inner wall of the outlet pipe 201 is coated with a photocatalyst layer. The outer wall of the filter tube 200 is provided with an ultraviolet lamp 202, and the ultraviolet lamp 202 is positioned between two adjacent rows of water outlet tubes 201. The photocatalyst performs photocatalytic degradation treatment on the cloth dyeing wastewater under the irradiation of the ultraviolet lamp 202. The water outlet pipe 201 can divide the wastewater into a plurality of strands of trickle flows, increase the contact area of the wastewater with gas and a photocatalyst, and improve the aeration efficiency and the photocatalytic degradation efficiency of the cloth dyeing wastewater.

The inner wall of the filtering pipe 200 is mounted with a filtering net 203. Can filter impurities such as cloth fiber in the cloth dyeing wastewater.

The lower part of the cover 300 is fixedly connected with a motor 301. The motor 301 has a rotation shaft. The rotation shaft passes through the cap 300 and extends into the filter tube 200. The rotating shaft is detachably connected with a brush 302, so that the brush 302 can be replaced. Preferably, the shaft and the brush 302 are coupled by a coupling. The pivoted brush 302 can prevent that impurity from blockking up the filter screen, also can snatch the cloth fibre in the waste water of dyeing cloth.

Preferably, the bottom of the tank 100 is upwardly protruded to form a boss 106, and the drain outlet 105 is opened on the upper surface of the boss 106. The arrangement of the boss 106 is to increase the contact time between the water flow and the air in the water outlet pipe 201 at the bottom of the filter pipe 200. If the bottom of the side wall of the filter pipe 200 is not communicated with the water outlet pipe 201, more water is accumulated at the bottom of the filter pipe 200.

When in use, the cloth dyeing wastewater enters the filter pipe 200 through the water inlet 103 and flows out of the water outlet pipe 201. The filter net 203 installed on the inner wall of the filter pipe 200 filters impurities such as cloth fiber in the wastewater. The rotating brush 302 prevents impurities from blocking the filter screen and also captures the fabric fibers in the dyeing wastewater. The waste water is treated by photocatalytic degradation through a photocatalyst layer coated on the inner wall of the water outlet pipe 201 and an ultraviolet lamp 202 arranged on the outer wall of the filter pipe 200.

While the above process is being performed, air or ozone may be injected into the tank 100 from the air inlet 101 to perform aeration treatment on the wastewater, so that organic matters in the wastewater are oxidized and decomposed.

The treated waste water flows out through the drain port 104. According to the actual requirement, the waste water can be directly recycled or further treated. Preferably, the treated wastewater flows directly from the drain 104 to the inlet of the dyeing machine for reuse.

When it is desired to clean the apparatus, the cover 300 may be removed to allow waste water contaminants in the filter pipe 200 to be discharged through the waste outlet 105, and the brush 302 may be replaced.

It is to be understood that: although the present invention has been described in some detail by way of the specific embodiments, these descriptions are not intended to limit the scope of the invention, and any changes in form and detail that do not exceed the scope of the claims are intended to fall within the scope of the invention.
