Environment-friendly paper machine

Abstract

The invention discloses an environment-friendly paper machine, which comprises a base, a working platform is fixedly installed at the upper end of the base, a headbox is fixedly installed at one end of the upper surface of the working platform, and a forming device is arranged on the side, close to the headbox, of the upper surface of the working platform; a squeezing assembly is arranged on the side, close to the forming device, of the upper surface of the working platform, a drying cylinder is arranged on the side, close to the squeezing assembly, of the upper surface of the working platform, and a drying assembly is arranged on the side, close to the drying cylinder, of the upper surface of the working platform. By arranging the headbox, wastewater cleaned by the forming device is purified and then injected into a heat-preservation heating water tank, the headbox can be preheated quickly after being heated by a heating plate, the startup preheating time is shortened, the processingefficiency is improved, the quality of paper products is guaranteed, and the heat-preservation heating water tank has a certain heat-preservation effect after being heated; the preheating time can bereduced when the machine is stopped and restarted again.

Description

technical field [0001] The invention relates to the technical field of papermaking equipment, in particular to an environment-friendly papermaking machine. Background technique [0002] A paper machine is a machine that makes paper pulp water suspensions that meet the requirements of papermaking through filter dehydration, mechanical extrusion dehydration, and drying. It mainly includes a forming section, a pressing section, and a drying section. The papermaking slurry can be sprayed to the forming wire to form a wet paper sheet. The press section can dehydrate the wet paper sheet by pressurization. The function of the drying section is to further help the dehydration of the wet paper sheet. Generally, a scraper is installed on the surface of the couch roll. There are several pressure roller holes on the surface of the couch roll. During the rotation of the couch roll, the water on the paper will enter the pressure roller holes. Due to the centrifugal force, the water in the...

Problems solved by technology

[0005] The purpose of the present invention is to provide an environment-friendly paper machine, which can solve the problem of the large temperature difference between the north and the south of our country, and the need for a long time when the paper machine is used in the cold winter area in the north by setting the headbox. In addition, the water used in the heat preservation and heating water tank is obtained by purifying the waste water after the molding device is cleaned, which improves the utilization rate of water resources of the device and avoids the waste of water resources , which has the effect of energy saving and environmental protection. The present invention solves the problem that the water pressure of the spray system is too high when it is in use, which will easily cause water splashes and affect the working environment, and the problem that the water pressure is low and cannot be cleaned thoroughly. , to solve the problems raised in the above background technology
