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 invention belongs to the technical field of papermaking waste slag feeding devices, in particular to a papermaking waste slag continuous feeding device for continuously transporting papermaking waste slag to a high-temperature closed cracking kettle. technical background [0002] In the field of comprehensive recycling of papermaking waste, it involves continuously and stably transporting materials into a closed high-temperature cracking tank for cracking. Since flammable and explosive pyrolysis gas is produced during the pyrolysis process, it is necessary to ensure the sealing of the feed inlet to prevent leakage of pyrolysis gas and avoid accidents. [0003] In order to solve the above problems, the patent document with the authorized announcement number of CN 201849944 U (the application date is 2010.11.04) discloses a feeding device for waste plastics treatment. Its structure includes a feeding cylinder and a The piston is fixedly connected to...

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
