Problems solved by technology

[0002] In the production process of printed circuit boards, wet film or dry film and ink need to be used. During the production, the film removal and development section needs to remove the wet film or dry film and ink coated and printed in the previous stage, which will generate a large amount of hazardous waste HW13 Commonly known as film slag; affected by the existing technology, the film slag produced by it has problems such as high moisture content, high viscosity, high disposal cost and difficult handling; therefore, traditional waste film slag often runs out during storage and transportation. dripping and leaking, so it is necessary to reduce the amount of ink in the waste film residue for storage and transportation

Embodiment 1

[0013] Such as figure 1 As shown, the present invention provides an ink-containing solid waste reduction system, including a feeding mechanism 1 , primary reduction equipment 2 , secondary reduction equipment 3 , transfer equipment 4 and an automatic control system 5 .

[0014] The feeding mechanism 1 is installed at the front end of the primary reduction device 2, and the rear end of the primary reduction device 2 and the front end of the secondary reduction device 3 are connected through the transfer device 4 .

[0015] The primary reduction equipment 2 includes a stirring device 21 for stirring waste materials, a pH adjusting device 22 for adding acidic materials to waste materials, and a centrifugal extrusion device 23 for centrifugally drying waste materials.

[0016] The secondary reduction equipment 3 includes a drying device 31 and a steam-water separation device 32 .

[0017] The automatic control system 5 is used to control the operation of the stirring device 21 ,...

Embodiment 2

[0031] The present invention also provides a method for reducing the amount of ink-containing solid waste, comprising the following steps:

[0032] S1, add acidic substances to the waste to adjust the pH to a predetermined pH value, then fully stir and coagulate;

[0033] S2, the condensed material is centrifugally dried and then extruded to achieve a first-level reduction;

[0034] S3, drying the extruded waste to achieve secondary weight reduction.

[0035] Wherein, the predetermined pH value in step S1 is 6.5-8.5; the drying time of the waste in step S3 is 7-8 hours.

[0036] The ink-containing solid waste reduction method provided in Example 2 of the present invention utilizes the chemical properties of the wet film / dry film and the ink, and utilizes the characteristics of solidification after acidification, and achieves a reduction in solid-liquid separation after centrifugal extrusion, and then Entering the baking system for high-temperature drying to achieve secondary...

Abstract

The invention provides a printing ink containing solid waste reduction system and method so that waste film residue reduction treatment can be achieved and storage and transportation can be convenient. A feeding mechanism, first-level reduction equipment, second-level reduction equipment, transferring equipment and an automatic control system are included. The feeding mechanism is arranged at thefront end of the first-level reduction equipment, and the rear end of the first-level reduction equipment and the front end of the second-level reduction equipment are connected through the transferring equipment. The first-level reduction equipment comprises a stirring device for stirring waste, a PH adjusting device for adding acid materials to waste, and a centrifugal extrusion device for conducting centrifugal spinning-dry on the waste. The second-level reduction equipment comprises a drying device and a steam-water separation device. The automatic control system is used for controlling work of the stirring device, the PH adjusting device, the centrifugal extrusion device, the drying device and the steam-water separation device.

Description

technical field [0001] The invention relates to the field of hazardous waste reduction treatment, in particular to an ink-containing solid waste reduction system and method. Background technique [0002] In the production process of printed circuit boards, wet film or dry film and ink need to be used. During the production, the film removal and development section needs to remove the wet film or dry film and ink coated and printed in the previous stage, which will generate a large amount of hazardous waste HW13 Commonly known as film slag; affected by the existing technology, the film slag produced by it has problems such as high moisture content, high viscosity, high disposal cost and difficult handling; therefore, traditional waste film slag often runs out during storage and transportation. Therefore, it is necessary to reduce the amount of ink in the waste film slag to facilitate storage and transportation. Contents of the invention [0003] The object of the present i...
