Description

Technical Field

[0001] This invention relates to the technical field of integrated draining and packaging equipment, specifically to an integrated draining and packaging equipment for polyester residue. Background Technology

[0002] Polyester production involves esterification and polycondensation processes, both of which produce residues. These residues can be unreacted materials or small-molecule materials. Eggplant (EG) is present in the reaction system, and when the residues are separated from the system, they are often mixed with EG. Manual cleaning of these residues can lead to the entrainment of some EG, which usually requires further processing for separation.

[0003] Most companies bag, settle, and then discharge any residue containing EG (ethylene oxide). This process requires manual handling of the residue, which can cause EG spillage and environmental pollution. Settling takes a long time, necessitating the suspension of the residue to allow some EG to drain. Some companies, to prevent EG from being trapped during bagging and settling, operate in designated areas with dikes. However, because the shape and state of the residue vary, EG cannot be completely drained over time. This method is not an effective way to separate EG from the residue.

[0004] Based on the above, this invention proposes an integrated equipment for draining and packaging polyester residue, which can effectively solve the above problems. Summary of the Invention

[0021] Compared with the prior art, the present invention has the following advantages and beneficial effects:

[0022] 1. Compared with existing technologies, this polyester residue draining and packaging equipment innovatively combines a lifting device, a heating device, and a transportation device to achieve an automated residue draining and packaging process. Furthermore, the lifting platform has a hoisting mechanism, facilitating manual handling of the residue. This effectively reduces manual operation time by 3 hours, and virtually eliminates EG (polyester waste gas) spillage on the ground, preventing environmental pollution.

[0023] 2. Compared with existing technologies, this polyester residue draining and packaging equipment innovatively allows for differentiated processing based on the shape and state of the residue. For residues in powder or filament form, the heating device can be turned on for direct and rapid heating to separate EG. For residues in block or large particle form, fine sand can be added to the drum device and stirred together to allow the fine sand to quickly absorb EG. Then, the fine sand is separated by vibration through the filter screen on the conveying and screening device without the need to turn on the heating device, which promotes the separation of EG and reduces the time by half compared to the traditional method.

[0024] 3. Compared with existing technologies, this polyester residue draining and packaging equipment innovatively eliminates the need for manual bagging of residues during collection; instead, the packaging bags are simply placed inside the packaging device. Attached Figure Description

[0064] Furthermore, in another embodiment, the lifting platform is provided with a fence 35.

[0065] The working principle of one embodiment of the present invention is as follows:

[0066] A polyester residue draining and packaging integrated equipment, when the residue tank 1 is transported to the feeding device 2 by the lifting device 38, the left lifting device of the lifting platform is activated so that the residue enters the feeding device 2. After standing for a period of time, some EG flows out of the first EG outlet 5. The first switch device 4 is turned on and the residue then enters the drum 10 for mixing. After mixing is completed, it is flipped and enters the heating device 12.

[0067] Depending on the state of the residue, if it is powder or filamentous, heating is turned on and heated for a period of time so that EG flows out from the first EG steam port 14; if it is lumpy or large particles, sand needs to be transported from the recovery heating device 21 into the drum 10 to mix with the residue, so that the sand absorbs EG and then enters the heating device 12. At this time, the heating device 12 can be turned on as needed.

[0068] The sand in the former state enters the conveying and screening device 17 and is directly transported to the baling tank 24. The sand in the latter state enters the conveying and screening device 17, which requires back-and-forth movement so that the sand enters the recycling and heating device 21 before being sent to the baling tank 24. The baling tank 24 has already been pre-filled with baling bags 31 by the baling device 25. The sand collected by the recycling and heating device 21 can be reheated by the heating device 12 to evaporate any incompletely evaporated EG. The separated EG is then collected in the process tower 34.
