Description
Technical Field
The utility model relates to a concentrated quick-witted technical field of many discs in papermaking equipment, concretely relates to concentrated quick-witted advance thick liquid case homogenate device of many discs.
Background
The multi-disc thickener is mainly used for thickening and washing slurry of a slurry line, the slurry flows into the slurry inlet box through the slurry inlet pipe, and then the slurry enters the slurry tank in an overflow mode. When the central shaft rotates, the fan-shaped plates (the disk is formed by combining the fan-shaped plates and is in a disc shape) on the disk are immersed in the slurry under the atmospheric pressure, the separation of the slurry is realized by the filter medium, the vacuum is gradually formed inside the water leg, the slurry layer adsorbed on the surface of the fan-shaped plates is thinner at the moment, a large amount of solid matters of fine fibers and fillers still exist in the filtered filtrate, and the concentration of the filtrate is higher, so that the filtrate is called turbid filtrate. With the continuous operation of the sector plate, the pulp layer on the sector plate becomes thicker gradually, and at the moment, the pulp layer plays a good role of filtering media, a large amount of fine solid matters can be intercepted, the quality of the filtrate is improved gradually, and the filtrate in the area is called as clear filtrate; the pulp layer is thickened along with the rotation of the fan-shaped plate, when the fan-shaped plate rotates out of the liquid surface, the dehydration is continued under the action of vacuum, the dryness of the pulp layer is further improved, then the pulp layer enters an atmospheric region, and when the edge of the fan-shaped plate is stripped by the slurry stripping water, the pulp layer forms self-rolling under the action of self gravity and falls into the pulp tank. The pulp enters a pulp tank through spiral conveying, the sector plates with the peeled pulp layer are transferred to a net washing area, and the next filtration cycle is carried out after washing.
The traditional slurry inlet box can not meet the requirements of a multi-disc thickener on the stability of the slurry speed and the flow in the slurry inlet box and the uniform longitudinal distribution of the slurry in the slurry inlet box.
And traditional advance thick liquid case structure is a cuboid shape, and the bottom easily forms the thick liquid blind area that flows all around, has influenced the velocity of flow, the stability of flow of thick liquid, and easily forms long-pending thick liquid.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a concentrated machine of many discs advances thick liquid case homogenate device.
In order to solve the technical problem, the utility model adopts the following technical scheme:
the utility model provides a concentrated quick-witted pulp case homogenate device that advances of many discs, is connected with into thick liquid pipe including advancing the thick liquid case box, advances the thick liquid case box and is equipped with the overflow mouth towards the upper portion position of thick liquid groove one side, advances the thick liquid case box and is connected its characterized in that through overflow mouth and thick liquid groove overflow: and a pulp homogenizing plate is arranged in the pulp inlet box body, is lower than the overflow port and is provided with pulp homogenizing holes in an upward arrangement manner.
The homogenate board is horizontally arranged.
The homogenate board is welded and fixed in the box body of the slurry inlet box.
The homogenizing holes are uniformly distributed on the homogenizing plate in a criss-cross mode.
The bottom of the pulp inlet box body is an arc-shaped bottom, and the lower part of the pulp inlet box body is guided to contract towards the pulp inlet pipe.
The overflow port is a rectangular overflow port.
The utility model has the advantages that:
the utility model discloses advancing the inside homogenate device that increases of thick liquid incasement, having guaranteed the stability of thick liquid speed, flow, make the escape of free air in the thick liquid to make the thick liquid advance thick liquid incasement longitudinal distribution even, satisfy the concentrated machine of many discs to advance the thick liquid incasement thick liquid speed, the stability of flow and the thick liquid advance the even requirement of thick liquid incasement longitudinal distribution.
The utility model simultaneously improves the cuboid structure of the traditional slurry inlet box, changes the bottom from a flat bottom to an arc bottom, and can make the flow velocity and the flow of the slurry more stable; and the lower part of the box body of the slurry inlet box is guided to the slurry inlet pipe to shrink, so that slurry can be longitudinally distributed more uniformly in the slurry inlet box, a slurry flowing blind area is thoroughly eliminated, and slurry accumulation is eliminated.
