Problems solved by technology

[0003] 1. The paint barrels containing the paint wastewater cannot be recycled and alternately used, and can only be treated once, which requires a large number of processing containers and complicated operations;
[0004] 2. If the waste water is not treated and poured directly into the sewer, the sewer will be blocked; if it is directly poured outdoors, it will pollute the environment; or if the flocculant is used to treat the pigment waste water, there is a problem of long flocculation time and poor flocculation effect, resulting in pigment particles and water The separation effect is poor, which greatly reduces the processing efficiency of the entire pigment process;
[0005] 3. The pigment particles and water after flocculation need to be separated by the filter material. The existing fixing method of the filter material requires more auxiliary equipment, which is time-consuming and laborious;

Embodiment 1

[0051] Embodiment 1: as Figure 1-3 Shown:

[0052] A device for treating painting paint wastewater, comprising a paint bucket 1, a filtering device and a flocculation bag, the paint bucket 1 is provided with a fixed component, and the filter device is installed on the fixing component; after the flocculation bag is mixed with the pigment wastewater, then Filter through the filter device, and clear water flows into the paint bucket 1;

[0053] The paint bucket 1 is used to fix the filter device. When the pen washing wastewater needs to be treated and filtered after the painting is completed, the dirty pigment particles are separated from the clean water through the filter device. The pen washing wastewater of suspended pigment particles, the flocculation material bag is used to form flocs in the pen washing water, so that the wastewater is divided into two layers of pigment particles and clear water, and the fixing component is used to fix the filter device on the paint bucke...

Embodiment 2

[0059] Embodiment 2: as Figure 4-5 Shown:

[0060] The fixed component is a fixed inner barrel 22, the bottom of the inner wall of the fixed inner barrel 22 is provided with a water seepage hole, and the outer wall of the fixed inner barrel 22 is provided with a protrusion 221, and the protrusion 221 is used to clamp the fixed inner barrel 22 on the upper inner wall of the paint barrel 1;

[0061] The fixed inner barrel 22 is similar to the liner in the teacup. The filter material 6 is laid in the fixed inner barrel 22. When the waste water is poured into the fixed inner barrel 22, the clear water falls from the filter material 6 and the seepage hole into the paint barrel 1, and the filter The material 6 will not be tapered due to the gravity of the water, but will remain in the original shape in the fixed inner barrel 22, which will help increase the contact area between the filter material 6 and the waste water, thereby effectively improving the filtration efficiency of the...

Embodiment 3

[0063] Embodiment 3: as Figure 6-7 , as shown in 9-10:

[0064] The fixed component is a support bracket 23 arranged on the top of the paint bucket 1, the middle of the support bracket 23 is hollowed out, and a flower-shaped filter hole 231 is arranged in the middle of the support bracket 23, and the filter hole 231 is used to fix the filter device;

[0065] The flower-shaped filter hole 231 is used to place the flower-shaped filter material 6, which is folded into a flower shape by the square filter material 6. The flower-shaped filter material 6 is used to filter waste water containing suspended pigment particles. When the waste water is poured into the filter material 6, the flower-shaped filter material Material 2 wraps waste water, and the use of flower-shaped filter material 6 is conducive to increasing the contact area between waste water and filter material 6. Except for the four corners of flower-shaped filter material 6, other areas of filter material 6 can be used ...

Abstract

The invention discloses a device for treating painting pigment wastewater and a treatment process thereof. The device comprises a pigment barrel, a filtering device and a flocculation material bag, a fixing assembly is arranged on the pigment barrel, and the filtering device is installed on the fixing assembly. After the flocculation material bag and the pigment wastewater are mixed in the pigment barrel, the flocculation material bag and the pigment wastewater are filtered by the filtering device. The device for treating painting pigment wastewater is scientific and reasonable in structure and safe and convenient to use, compared with an existing mode that waste water is poured to the outdoor or a sewer after a painting pigment pen is cleaned, the treatment device does not need to pour dirty waste water to the outdoor, waste water is not required to be poured into a sewer, and the waste water is only required to be flocculated and filtered to obtain clear water, so that the function that one barrel of clear water can wash the drawing pen for multiple times is realized, the problem that dirty pen washing water containing pigment particles pollutes the outdoor environment is solved, and the problem that the pigment particles block the sewer is also solved.

Description

technical field [0001] The invention relates to the technical field of pigment wastewater treatment, in particular to a device for treating painting pigment wastewater and a treatment process thereof. Background technique [0002] There are many kinds of pigments, complex structures, various types of intermediates, complex production processes, especially many side reactions in the production process, large pollution emissions, and some pigment wastewater contains by-products, impurities, unreacted raw materials and leaked products. , which often contains a large amount of organic matter, so the wastewater has high chroma, stable properties, large pH changes, and unstable water quality. Due to the above characteristics of pigment wastewater, it has become a difficult problem in the field of industrial wastewater treatment. Pigment wastewater is in the process of treatment. There are following difficulties: [0003] 1. The paint barrels containing the paint wastewater cannot...
