Inclined wire papermaking apparatus

Abstract

The invention relates to an inclined wire papermaking apparatus, comprising a constant pressure pulp-distributing tank, a stainless steel pulp distributor, an inclined wire pulp flow box, a dewatering box, a breast roll, and a forming wire mesh. The constant pressure pulp-distributing tank comprises an upper tank body, a lower tank body, support legs and an orifice plate. The stainless steel pulp distributor comprises a pulp distributor body, and a plurality of pipes made of stainless steel are distributed on the pulp distributor body. The inclined wire pulp flow box comprises a box body, an upper lip component is movably arranged in the box body, the box body is of closed structure, the upper lip component comprises a rear upper lip plate and a front upper lip plate, the rear upper lip plate is rotationally connected with the front upper lip plate, a plurality of transverse beams are fixed on the box body, a first cylinder, a first turbine box, a second cylinder and a second turbine box are fixed on the transverse beams, and the dewatering box comprises a box body, a lower dewatering mesh, an upper dewatering mesh, a drain pipe and a pulp discharging pipe. The inclined wire papermaking apparatus has the advantages of reasonable parameter setting, good pulp flow uniformity and stability, and good forming effect.

Description

technical field [0001] The invention relates to the field of papermaking equipment, in particular to flow conveying and forming components. Background technique [0002] The paper machine is a machine that makes the pulp water suspension that meets the requirements of papermaking into paper through the process of dehydration through filter screen, mechanical extrusion dehydration and drying. The paper machine includes three main parts of forming, pressing and drying to complete the above process, and is equipped with necessary finishing, coiling and transmission devices, as well as pulp supply, pulp and white water circulation, vacuum, ventilation and exhaust, damage Paper handling and lubrication, automatic control and other auxiliary systems. The forming part includes structures such as headbox, breast roll, forming wire, suction box and couch roll; before the forming part is the flow delivery part, and the flow delivery part generally includes a buffer tank or a slurry d...

Problems solved by technology

[0006] The traditional mesh dehydration is dehydration with a single-layer dewatering mesh. This kind of mesh has high elongation, large deformation of the normal mesh, and uneven dehydration, resulting in high white water concentration, poor paper evenness, and large paper moisture deviation.

Moreover, many of the existing dehydration tanks are manually controlled, which has low degree of automation, poor precision, and consumes a lot of manpower and material resources.
