Low-gram-weight paper impurity direct-discharging slag remover

Abstract

The invention discloses a low-gram-weight paper impurity direct-discharging slag remover. The low-gram-weight paper impurity direct-discharging slag remover comprises a rotating pulp inlet head, a cone tube and a ceramic slag discharge nozzle, wherein the rotating pulp inlet head comprises a straight pipe section, an annular arc-shaped pipe section and a good pulp liquid outlet pipe, the straightpipe section is connected with the annular arc-shaped pipe section, the good pulp liquid outlet pipe is located at the axis of the annular arc-shaped pipe section, a gradual shrink port is formed in the lower portion of the good pulp liquid outlet pipe, a liquid outlet pipe connector is arranged on the upper portion of the good pulp liquid outlet pipe, the liquid outlet pipe connector is perpendicular to the good pulp liquid outlet pipe, the lower portion of the annular arc-shaped pipe section is connected with the large-diameter side of the cone tube, the small-diameter side of the cone tubeis connected with the ceramic slag discharge nozzle, and the ceramic slag discharge nozzle is provided with a ceramic slag discharge nozzle junction head. The low-gram-weight paper impurity direct-discharging slag remover has the advantages that the slag removal effect is good, and the structure is simple, and the energy is saved.

Description

Technical field [0001] The invention relates to the technical field of a low-gram-weight paper pulping purification treatment device, and more specifically, to a low-gram-weight paper-type impurity direct slag removal device. Background technique [0002] At present, in the paper pulping process, it is usually necessary to remove the large-diameter heavy impurities in the pulp in the pure link of the pulp. The existing slag remover uses centrifuges and other equipment to use the different specific gravity of the heavy impurities and the pulp. The centrifugal force of the high-speed rotation of the centrifuge separates heavy impurities from the pulp. However, this kind of equipment requires additional power supply. Therefore, the removal of pulp requires additional purchase of centrifugal equipment and the huge amount of centrifugal equipment. Energy consumption, thereby increasing production costs. [0003] At present, in the paper industry, the concentration of the pulp in the cl...

Problems solved by technology

[0002] At present, in the papermaking pulping process, in the pulp purification process, it is usually necessary to remove large-diameter heavy impurities in the pulp. The existing slag remover uses centrifuges and other equipment to take advantage of the difference in the specific gravity of heavy impurities and pulp. The centrifugal force of the high-speed rotation of the centrifuge is a kind of equipment that separates the heavy impurities from the pulp, but this equipment requires additional power supply, so that it is necessary to purchase additional centrifugal equipment for pulp removal, and at the same time bear the huge cost of centrifugal equipment. energy consumption, thereby increasing production costs

[0003] At present, in the paper industry, the pulp concentration of the deslagging device is increased by controlling the dilution water at the bottom slag outlet, but the concentration will decrease correspondingly on low-weight paper types. If the dilution water is still used, the water consumption will be increased. increase power consumption
