Continuous feeding device for papermaking waste residue

Abstract

A continuous feeding device for papermaking waste residue belongs to the technical field of feeding devices for papermaking waste residue and comprises a feeding barrel, a feeding cylinder, a pressing bin and a feeding bin. The feeding cylinder is movably sleeved in the feeding barrel, the pressing bin is disposed above the feeding barrel and communicated with the feeding barrel, the feeding barrel is perpendicularly connected with the pressing bin, an arc-shaped smooth transitional structure is disposed at a joint of the feeding barrel and the pressing bin, a turning plate used for pressing materials is fittingly disposed in the pressing bin, the feeding cylinder is fixedly connected with a piston, the piston is fixedly connected with a piston rod, and a cooling jacket is fittingly arranged on the outside of the feeding barrel. The cooling jacket is added to the outside of the feeding barrel, the temperature of the materials is reduced, and a sealing function is realized. In addition, a rod sleeve, the piston rod, the piston and the feeding cylinder form a pushing device, and feeding continuity and stability of a system are guaranteed. Furthermore, the smooth transitional structure is arranged at the joint, and accordingly the continuous feeding device for papermaking waste residue can continuously, stably and safely feed the papermaking waste residue required by cracking of a high-temperature sealing cracking kettle.

Description

Technical field [0001] The present invention is the technology field of papermaking waste residue feed devices, which specifically involves a continuous feed device for papermaking waste residue to continuously transport papermaking waste residue to high -temperature densely closed cracks. technical background [0002] In the field of comprehensive recycling of papermaking scum, it involves continuously and stably transport the material into a closed high -temperature cracking kettle for cracked.Due to the flammable and explosive qi gas during the cracking process, the sealing nature of the inlet of the feed must be ensured, the leakage of the qi is prevented, and the accident occurs. [0003] In order to solve the above problems, the authorized announcement number is CN 201849944 U (the application date is 2010.11.04) patent literature disclosed a feed device for waste plastic treatment.Pistons, the piston and the piston rod are fixed. The inlet tube is provided with a warehouse...

AI Technical Summary

Problems solved by technology

The above-mentioned equipment can realize the function of continuously and airtightly conveying materials to the high-temperature cracking kettle to a certain extent; but in the actual operation process, the above-mentioned equipment will have the following problems: If they are connected together, it is easy to melt due to high temperature, which will cause the material in the barrel to lose its sealing function, and the cracking gas in the high-temperature cracking kettle will leak out, which will easily cause accidents; 2. The feeding barrel and feeding bin of the above equipment are connected vertically. There is no smooth transition in the middle, and the piston pushes the material to the joint, which is prone to material dragging and shearing, which makes the material unable to continue to move, and may cause the entire feeding system to collapse in severe cases
