Problems solved by technology

[0004] Waste polyester recycling production technology has a process of separating bottle flakes and label paper. At present, most of the scattered recycled waste polyester bottles are picked on the ground manually. This processing method is not only labor-intensive, but also consumes a lot of labor. The production and output are very low, and it is easy to cause mess on the site and affect the health of the staff

Embodiment 1

[0056] Please refer to figure 1 , a recycled plastic label paper processing equipment, including a cleaning and separating device, a filtering device, a re-cleaning and separating device, a dehydration device, a drying device, a first lifting and conveying device, a second lifting and conveying device and a third lifting and conveying device, the The cleaning and separating device includes a pre-rinsing device, a cooking device and a re-rinsing device connected in sequence;

[0057] Both the pre-rinsing device and the re-rinsing device include a rinsing tank for separating the material into floating label paper and sinking bottle flakes, the rinsing tank is filled with a rinsing liquid, and the density of the rinsing liquid is between that of the label paper Between the density and the flake density;

[0058] The rinsing tank is provided with turning blades for pushing the label paper from the feeding end of the rinsing tank to the discharging end of the rinsing tank and for ...

Embodiment 2

[0064] A method for processing recycled plastic label paper, comprising the steps of:

[0065] Step 1. Put the mixture of bottle flakes and label paper into the rinsing liquid for rinsing. The density of the rinsing liquid is between the density of the label paper and the density of the bottle flakes, so that the bottle flakes sink in the rinsing liquid, and the label paper is Float in the rinsing liquid, collect the sinking bottle flakes, and discharge the floating label paper together with the rinsed sewage;

[0066] Step 2. Elevate and transport the bottle flakes collected in step 1, then cook them, dehydrate them after cooking, lift and convey the dehydrated bottle flakes, put them into the rinse solution for rinsing, collect the sinking bottle flakes, and remove the floating labels The paper is discharged together with the rinsed sewage;

[0067] Step 3, filtering the mixture of label paper and sewage discharged in step 1 and step 2 to obtain label paper containing sundr...

Abstract

The invention provides reprocessed plastic label paper processing equipment and a processing method. The equipment comprises a washing and separating device, a filtering device, a rewashing and separating device, a dehydration device, a drying device, a first elevating conveying device, a second elevating conveying device and a third elevating conveying device. The washing and separating device comprises a pre-rinsing device, a stewing device and a re-rinsing device which are connected sequentially. The pre-rinsing device and the re-rinsing device each comprise a rinsing groove which is used for separating materials into label paper floating upwards and bottle grades sinking downwards. The rinsing grooves contain rinsing liquid. Density of the rinsing liquid is between label paper density and bottle grade density. The equipment has the beneficial effect that by means of the washing and separating device, the filtering device, the rewashing and separating device, the dehydration device and the drying device which are sequentially connected, label paper processing can be carried out automatically after the bottle grades and the label paper are separated.

Description

technical field [0001] The invention relates to processing equipment and a processing method for recycled plastic label paper. Background technique [0002] In recent years, the recycling of waste polyester bottles and the utilization of recycled materials have been successful in various countries and have accumulated certain experience. Compared with developed countries, the development of recycling waste polyester bottles in China started late and at a slow pace. With the strong support of the industrial policy-making department, the development of the recycled polyester industry is thriving. [0003] From the perspective of environmental protection and resource reuse, the recycling of waste polyester bottles is a project that benefits the country and the people and has broad economic benefits. Turn the recyclable polyester bottles that pollute the environment and are not easy to digest into treasures, continue to be used in people's lives, greatly reduce the pressure on ...
