Description
Technical field
The utility model relates to paper industry pulping technique, is specifically related to a kind of wood chip cleaning device with cone rotor.
Background technology
The raw material of papermaking generally includes forage and timber, usually based on timber.Papermaking comprises is cut into round log section or wood chip by timber, round log section or wood chip are made the step of slurries, and before round log section or wood chip are made slurries, in order to not affect the normal work of fiberizer, extend the service life of mill, usually need to clean round log section or wood chip, to remove the foreign material of self, especially sandstone, and, according to hot water cleaning, also contribute to the softening of round log section or wood chip, be conducive to carrying out smoothly of refining process.
What usually adopt at present is spiral wood chip cleaning device, by the rotation of the helical axis of a band helical blade, wood chip is squeezed in water and cleans, simultaneously under the effect of helical blade, be fed forward by wood chip.Above-mentioned cleaning device owing to only having carried out once cleaning to wood chip, and does not also carry out dehydration to wood chip and is filtered dry operation, therefore there is the halfway problem of eliminating impurities.
Utility model content
The wood chip cleaning device with cone rotor that the utility model provides a kind of wood chip to clean up.
This programme is as follows: with the wood chip cleaning device of cone rotor, comprise funnelform rinse bath, washings are loaded with in the inside of rinse bath, the inside of rinse bath is provided with can pivotal cone rotor along the horizontal plane, cone rotor immerses in washings, the top of rinse bath has charging aperture, sidewall has clear water water inlet and circulation water inlet, the bottom of rinse bath is provided with the refuse collecting groove be communicated with rinse bath, the top of rinse bath is communicated with feeding pipe, drench pit is provided with in the side direction of rinse bath, the top of drench pit is provided with the dewatering screen be overlapped on cell wall, dewatering screen is communicated with conveyance conduit, the bottom of drench pit is provided with circulating outlet, circulating outlet is communicated with circulating water pipe, circulating water pipe is provided with water circulating pump and scummer successively, circulating water pipe access circulation water inlet.
This programme operation principle is as follows: wood chip enters in rinse bath via charging aperture, because clear water and recirculated water tangentially enter in rinse bath, and under the rotarily driving of cone rotor, wood chip is made to move towards the funnel bottom of rinse bath rapidly with the eddying motion of current, then rise to center, under centrifugal force and turbulent flow, foreign material are separated from wood chip, the wood chip after washing overflows with current via conveyance conduit and enters dewatering screen dehydration.Wood chip after dehydration transfers out, and the washings deviate from are via flowing back to rinse bath after the scummer slagging-off on circulating water pipe, again utilize.
The utility model first embathes wood chip, then dewaters to wood chip, and what wood chip can be made to clean is cleaner, and removal of impurities is thorough.
Further, in order to enable wood chip successfully carry along dewatering screen, dewatering screen is obliquely installed, and one end that dewatering screen is communicated with feeding pipe is high, and the one end away from feeding pipe is low.
Further, the mounting groove of upper opening is provided with in the side direction of drench pit, the wood chip conveying screw rod that can rotate at perpendicular is provided with in mounting groove, the end of dewatering screen is positioned at the notch of mounting groove, rolling tangential direction along wood chip conveying screw rod is provided with the screen of inclination, screen is positioned in filter pocket, and filter pocket accesses scummer by pipeline.Further increase screen carries out drainage operation to wood chip, makes cleaning more thorough.
Further, vibrator is provided with in the bottom of dewatering screen.The vibration of vibrator contributes to dehydration and discharging.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment.
Detailed description of the invention
Below by detailed description of the invention, the utility model is described in further detail:
