Abstract
The invention discloses a rotary drum type wood chip washing device which can wash wood chips clean. The rotary drum type wood chip washing device comprises a funneled washing tank, wherein a rotary drum type sundry separator is arranged in the washing tank, a wood chip inlet is formed at the top of the washing tank, and a sundry outlet is formed at the bottom of the washing tank. A sundry collector is arranged below the sundry outlet. A circulating water inlet is arranged on the side wall on the lower portion of the washing tank. A wood chip conveying drum is arranged in the side direction of the washing tank and is communicated with the washing tank through a wood chip conveying channel. Washing water is contained in the washing tank. The rotary drum type sundry separator is soaked in the washing water, and the liquid level of the washing water is higher than the bottom wall of the wood chip conveying channel. A rotatable wood chip dewatering conveying screw is arranged at the inner edge of the wood chip conveying drum in the axial direction of the wood chip conveying drum, a screen plate is arranged on the lower portion of the wood chip dewatering conveying screw in the axial direction of the wood chip conveying drum, and a sewage outlet is arranged at the bottom of the wood chip conveying drum and is communicated with a circulating pipe. A circulating water pump and a sand remover are arranged on the circulating pipe, and the circulating pipe is communicated with the circulating water inlet.
Description
Technical field
The present invention relates to pulping technology for paper-making, be specifically related to a kind of rotary drum cleaning equipment of wood chips.
Background technology
Raw material in paper-making process is round log section or wood chip normally, before round log section or wood chip are made slurries, need to wash round log section or wood chip, with clear sandstone, knaur or metal sundries wherein, be beneficial to the normal operation of fiberizer, extend the service life of mill or grinding stone, improve the moisture content of round log section or wood chip.Current common way is placed on by wood chip in sink, by the foreign material cleaned on wood chip that run up of water in sink, after cleaning, got rid of by water from sink, such mode Problems existing is, wood chip after washing itself may have foreign material to remain, and water waste is more serious.
Summary of the invention
The invention provides a kind of rotary drum cleaning equipment of wood chips, not thorough to solve the cleaning of existing wood chip, cleaning waste water problem.
This programme is as follows: rotary drum cleaning equipment of wood chips, comprise funnelform sink, the inside of sink is provided with rotary drum sundries separator, the top of sink has chip feed, the bottom of sink is provided with miscellaneous object outlet, miscellaneous object outlet place is provided with filter screen, the below of miscellaneous object outlet is provided with sundries collector, the sidewall of sink bottom is provided with circulating water intake, the side direction of sink is provided with wood chip transport tube, wood chip transport tube is communicated with by wood chip feed track with sink, washings are loaded with in sink, rotary drum sundries separator immerses washings, the liquid level of washings is higher than the diapire of wood chip feed track, rotating wood chip dehydration conveying screw rod is axially arranged with along it in wood chip transport tube, the bottom of wood chip dehydration conveying screw rod is axially arranged with sieve plate along wood chip transport tube, outlet of sewer is provided with in the bottom of wood chip transport tube, outlet of sewer is connected with circulating line, circulating line is provided with water circulating pump and desander, circulating line is connected with the circulating water intake of sink.
This programme operation principle is as follows: wood chip is delivered in sink via chip feed, density due to wood chip is less than the density of water, when there is no barrel tumbler, wood chip will swim in the surface of water, but rotate drum-type sundries separator because this device is provided with, when rotating the rotation of drum-type sundries separator, agitator treating water, wood chip is immersed in washings, abundant washing, and rotate the effect of tangential force at barrel tumbler under, washings are made to be delivered in wood chip transport tube via wood chip feed track together with the wood chip after washing, dewater in the wood chip dehydration conveying screw rod rotated, and wood chip transport tube is sent under the propelling movement of wood chip dehydration conveying screw rod screw thread.The washings be separated with wood chip enter circulating line via outlet of sewer, under the effect of water circulating pump, via desander desanding, pump back sink.
Compared with prior art, wood chip is through washing and dehydration two processes, and eliminating impurities more thorough, washings recycle, and have saved paper making water in the present invention.
Further, wood chip transport tube, wood chip dehydration conveying screw rod and sieve plate are all obliquely installed, and the one end be communicated with wood chip feed track is low, and the one end away from wood chip feed track is high, and outlet of sewer is arranged on the bottom near wood chip feed track one end.The design that wood chip transport tube, wood chip dehydration conveying screw rod and sieve plate are all obliquely installed, is more conducive to the dehydration of wood chip.
Further, outlet of sewer is funnel-form, is convenient to the convergence of sewage.
Further, be provided with residual cake valve in the bottom of desander and sundries collector, for regular, dirt in desander and sundries collector discharged.
