Description

Technical Field

[0001] This utility model belongs to the field of chemical fiber waste oil recycling, and specifically relates to a waste oil recycling device for chemical fiber reaction vessels. Background Technology

[0002] In existing technologies, the production process of recycled chemical fiber reactors is a key step in reprocessing recycled chemical fibers (such as polyester and nylon) into new fibers through chemical reactions. Its core steps include raw material processing, depolymerization, purification, repolymerization, and subsequent processing. Currently, the production process of recycled chemical fiber reactors generates a large amount of waste oil, which mainly consists of various organic substances and additives. These additives are essential textile auxiliaries used in the production and processing of chemical fibers. At room temperature, the waste oil typically becomes extremely viscous, making it difficult to clean and transport.

[0003] The current problems with the recycling of chemical fiber waste oil from reactors are as follows: 1. It is generally collected manually by the recyclers. Due to the cumbersome operation process, the tools used for recycling waste oil must be cleaned, and the waste oil must be prevented from spilling during transportation, resulting in low work efficiency; 2. Chemical fiber waste oil has a complex composition, containing a variety of organic substances and additives. The treatment of these components requires specific equipment, which increases the difficulty of collection and treatment; 3. A small amount of industrial waste gas is generated during the production process, which requires supporting purification equipment for treatment. Utility Model Content

[0004] The purpose of this invention is to provide a waste oil recovery device for chemical fiber reactors, which can comprehensively treat and utilize the waste oil generated during the production process of chemical fiber reactors, thereby reducing environmental pollution and saving energy, and realizing the recovery of chemical fiber waste oil.

[0005] The purpose of this utility model is achieved as follows: A waste oil recovery device for a chemical fiber reactor includes a vertically arranged cylinder. Several feed pipes are provided on the side of the upper end of the cylinder, and the feed pipes are connected to the inside of the cylinder. A steam heating coil and a filter screen are vertically arranged inside the cylinder. The steam heating coil is arranged around the filter screen. A discharge pipe is provided at the lower end of the cylinder, and the discharge pipe is connected to the inside of the cylinder. The steam inlet and outlet ends of the steam heating coil extend out of the cylinder and are provided with steam valves. Several support legs are also provided at the lower end of the cylinder.

[0006] This utility model's waste oil recovery device is installed at a high location, with a storage tank placed downstairs to receive the waste oil. During operation, the operator opens the feed valve according to production needs, allowing the waste oil from the chemical fiber reactor to enter the cylinder through the feed pipe. The steam heating coil has both its inlet and outlet ends extending out of the device and equipped with steam valves. Opening these valves allows steam to enter the heating coil and heat the waste oil, softening and thinning the viscous oil. Large particles are filtered out through a filter screen. Finally, the operator opens the discharge valve, allowing the waste oil to flow naturally through the discharge pipe to the storage tank downstairs. The waste oil recovery device can be placed below the waste oil discharge port of the reactor, reducing some of the cleaning work by shortening the pipeline length. Compared with existing technologies, the advantages of this utility model are: comprehensive treatment and utilization of waste oil generated during the production process of the chemical fiber reactor, reducing environmental pollution and saving energy, and achieving the recovery of waste oil from chemical fibers.

[0009] As a further improvement of this utility model, the steam heating coil and filter screen are both circular, and the axes of the cylinder, steam heating coil, and filter screen are aligned. The filter screen includes a horizontal top mesh and a circular side mesh. Both the top mesh and the side mesh are covered with multiple mesh holes. The lower end of the side mesh is fixed to the lower end plate. The lower end plate of the cylinder has a discharge port connected to the discharge pipe, and the discharge port is located below the top mesh of the filter screen. The steam heating coil is supported on the lower end plate, and the side mesh surrounds the discharge port. The waste oil from chemical fibers can only be discharged from the discharge pipe after being filtered by the filter screen.

[0010] As a further improvement of this utility model, the discharge pipe includes an inner pipe body and an outer pipe body. The inner pipe body is correspondingly arranged with the discharge port, and a heating jacket is formed between the outer pipe body and the inner pipe body.
