Problems solved by technology

However, this technology is by no means perfect. Generally, papermaking waste residues have a relatively high water content. However, the catalytic cracking process of waste plastics in the latter stage of the process requires raw materials to have a high degree of dryness. Therefore, reducing the water content of papermaking waste residues is the key An important technical difficulty of the craft
At present, there are mainly the following solutions: 1. Natural drying, the moisture of papermaking waste residues is removed by sun exposure and air drying. The advantage is energy saving, but the disadvantage is that it is too dependent on weather conditions, and the production effect at night is poor, which is not conducive to the stability of production.
2. Heating and drying. The papermaking waste residue is dried by the heating device. The heating method can be divided into electric heating, fuel oil heating and exhaust gas recovery. Among them, the electric heating and fuel heating are characterized by strong drying stability, but they can high power consumption
The recovery tail gas heating refers to the technology that the combustion tail gas produced by the heating device is recycled to the waste residue drying device to use its heat during the cracking stage of the comprehensive recycling and utilization of papermaking waste residue process. This method can make full use of energy and has low cost, but Limited drying capacity, highly dependent on the operating conditions of the heating unit

Abstract

A device for wringing papermaking waste residues belongs to the technical field of devices for wringing the papermaking waste residues, and comprises a base, wherein an electric motor, a transmission gear which is connected with the electric motor through a first coupling and a bearing base which is connected with the transmission gear through a second coupling are sequentially arranged on the base through a support, the other end of the bearing base is provided and connected with a shaftless spiral body in a matching way through a third coupling, a feed bin is arranged above one end of the shaftless spiral body in a matching way, which is close to the bearing base, a shaftless spiral body shell is arranged outside the shaftless spiral body, and is connected with a material seal shell through a flange, and drain holes are respectively arranged on the shaftless spiral body shell and the material seal shell in a matching way. The device adopts the technology, has a simple structure, thematerial extruding strength is increased, and the wringing effect is improved; and one end of the shaftless spiral body shell is connected with the material seal shell, the material traveling distance and the material forward resistance are increased, the extruding force on the material is improved, the wringing effect is enhanced, and the continuity and stability of the wringing process are protected.

Description

technical field [0001] The invention belongs to the technical field of water-squeezing devices for papermaking waste slag, and in particular relates to a device for water-squeezing papermaking waste slag that reduces the water content of papermaking waste slag with low cost, large processing capacity and strong independence. technical background [0002] Waste paper recycling is an effective way to solve the shortage of raw materials for papermaking. It can save resources and reduce costs. It is an important measure for my country's paper industry to solve the problem of fiber raw materials. However, a large amount of waste residue will be generated after using waste paper to make paper. The production and sales of hundreds of paper mills in Fuyang City, Zhejiang Province account for more than 60% of the domestic market. According to statistics, more than 2,000 tons of waste residues are produced every day, and 650,000 tons of waste plastics are produced throughout the year. ...
