Abstract
The invention discloses cleaning equipment of wood chips, which is provided with a box body and rotative stirring rolls and is characterized in that the box body is in a fixed box-type structure, is divided into a rectangular upper part and a biconical low part, and is internally provided with a stirring roll A and a stirring roll B which make rotational motion along the same direction, and the roll surface of each stirring roll is regularly distributed with a plurality of rows of shifting forks. The cleaning equipment in the invention has the advantages of good cleaning effect and high impurity removal rate.
Description
Technical field
The present invention relates to a kind of cleaning equipment of wood chips that is applied to pulping and paper-making.
Background technology
Domestic wood pulp factory washs or adopts simple and easy wash mill to handle wood chip is less at present, generally adopts the common sieve that waves once simply to screen, and can only isolate the thick wooden unit in the wood chip.Yet, complicated along with the aggravation of market competition and commodity wood chip purchase channel, chip quality reduces, wood chip impurity ratio example obviously increases, and a large amount of silt particle iron-stone class impurity can't separate with method for screening, sneak into the pulping by cooking system, cause flow process to stop up and instability, especially equipment is caused violent impact and wearing and tearing, the system maintenance expense is increased severely, cause the enterprise operation cost to raise.
Summary of the invention
The object of the present invention is to provide the cleaning equipment of wood chips that a kind of clean result is good, removal of impurity is high.
The objective of the invention is to be achieved through the following technical solutions: a kind of cleaning equipment of wood chips, have casing and rotating agitating roller, it is characterized in that: casing is fixing case structure, divide two parts up and down, top is rectangle, the bottom is the biconial structure, is furnished with the agitating roller A and the agitating roller B that do gyration in the same way in the casing, the roll surface of the every agitating roller plurality of rows shift fork that distributes regularly.
Described two agitating roller equal diameters, rotating speed unanimity, turn to identical.
1. the present invention makes full use of the specific gravity difference of law of buoyancy and different material, reaches heavy seeds purpose in effective separation wood chip, thereby guarantees all can reach comparatively ideal impurity-eliminating effect under the different material qualify requirement.
2. adopt two agitating roller designs, its stirring action is more abundant, and detersive efficiency is higher, can make burs such as the earth that is attached to the wood chip surface, rotten class impurity and wood chip effectively be washed removing, has positive effect to improving pulp quality.
3. alleviate the wearing and tearing of flow sheet equipment, significantly reduce the equipment operation maintenance expense.
The present invention has the advantage that clean result is good, removal of impurity is high.
Description of drawings
Fig. 1 is a structure chart of the present invention,
Fig. 2 is an exterior view of the present invention;
In the accompanying drawing: 1, do not wash the wood chip import; 2, wash back wood chip outlet; 3, wash cycle water inlet; 4, slag-drip opening A; 5, slag-drip opening B; 6, casing; 7, agitating roller A; 8, agitating roller B; 9, shift fork; 10, transmission case; 11, residual cake valve; 12, peep hole; 13, bearing block.
The specific embodiment
Further illustrate content of the present invention below in conjunction with accompanying drawing and instantiation, but these embodiment do not limit protection scope of the present invention.
As depicted in figs. 1 and 2, cleaning equipment of wood chips of the present invention, have casing 6 and rotating agitating roller, casing 6 is fixing case structure, divides two parts up and down, and top is rectangle, the bottom is the biconial structure, be furnished with the agitating roller A and the agitating roller B that do gyration in the same way in the casing, the roll surface of every agitating roller 9,2 transmission cases of plurality of rows shift fork that distribute regularly drive the revolution of 2 agitating rollers respectively.
During work: recirculated water is full of washings from the 4 injection casings that enter the mouth in the casing, wood chip to be washed adds from import 1, and two agitating rollers turn round in the same direction with certain rotating speed.Because the proportion of wood chip is lighter than water, wood chip floats on the surface, at first constantly dial in wood chip in the water by the shift fork on the agitating roller A7 9, carry out the washing first time, wood chip floats forward again, through the shift fork 9 on the agitating roller B8 wood chip is dialled in the water once more again, entered next procedure with water from discharging opening 2 outflows at last, finish whole washing process.
In washing process, weight automatic sedimentations such as the ironware stone that is mingled with in the wood chip stick to the earth and the decadent nature material of wood chip to the hypocone of casing, break away from wood chip and fall into the water under violent stirring action, the wood chip on wood chip surface and ease of solubility resin also dissolve in the water in washing process.These impurity that have a strong impact on pulp quality are removed one by one, thereby reach the purpose that improves the wood chip cleanliness factor.Heavy seeds natural subsidence in water is discharged by the timing automatic residual cake valve that is provided with to the hypocone of casing, swims in the light impurities in the washings, can adopt the method for filtration to remove by next procedure.
