Abstract
A method for washing wood chips with water includes the first water washing, the second water washing and dewatering. Its water-washing apparatus is composed of the first water washer, the second water washer and spiral dewatering machine. Its advantages are simple structure, less loss of wood chips, and low electric consumption.
Description
(1) technical field:
The present invention establishes the chip washing technology that relates to when getting the raw materials ready in the building board production process, and the present invention also establishes the chip washing equipment that relates to realizing that above-mentioned technology designs.
(2) background technology:
When making wood-based plate, must earlier the wood chip as raw material be cleaned, impurity such as the silt in the wood chip, sandstone, ironware, iron fourth are washed, then, moisture content in the wood chip is removed, pass through Transport Machinery again, washed wood chip is sent in the defibrator, carry out defibrator process, thereby prepare wood fibre.Cleaning the purpose of wood chip, is in order to reduce the loss of impurity to the grinding machine mill, to reduce power consumption of the mill simultaneously, improving fiber quality on the other hand, the moisture content of stable fibers on the one hand.Existing chip washing technology is: wood chip is through being delivered to rinsing machine, dewaters through wood chip pump pump to spiral dewater to bin before pump in the back of coming out from rinsing machine.This technology not only water consumption, power consumption is big, and when wood chip pump pumping wood chip, can damage a large amount of wood chips, cause the significant wastage of chip raw material, and, influence machine and run well, therefore because impaired numerous chip dusts very easily snap in the treatment hole of spiral dewater drainage screen cloth, the treatment hole of being opened on the drainage screen cloth of existing spiral dewater must be inner small and outside big bellmouth; This has increased the cost of manufacture and the manufacture difficulty of spiral dewater.Because the existing equipment price is very high, and energy consumption is very high, has greatly improved the cost of manufacture of wood-based plate, this equipment all is reluctant to use by therefore a lot of producers.
(3) summary of the invention:
It is few that the present invention will disclose a kind of power consumption, and the wood chip proportion of goods damageds are little, and impurity is eliminated chip washing technology completely; The present invention also will be disclosed as the chip washing equipment of realizing above-mentioned technology and designing.
Chip washing technology, step is as follows, wood chip is through being delivered to the first road rinsing machine charging aperture, and behind first road washing machine washing, wood chip comes out from the first road rinsing machine discharging opening, directly enter the second road rinsing machine charging aperture, after the second road rinsing machine cleaning, come out from the second road rinsing machine discharging opening, directly enter the spiral dewater charging aperture and dewater, wood chip after dehydration comes out from the spiral dewater discharging opening, finishes whole cleaning process.
The difference of chip washing equipment of the present invention and prior art is, this chip washing equipment, constitute by the first road rinsing machine and charging aperture spiral dewater over against the second road rinsing machine of the first road rinsing machine discharging opening and charging aperture over against the second road rinsing machine discharging opening.
Difference with the prior art of the present invention also is, in the said equipment, described chip washer can be existing any, but the general first road rinsing machine adopts existing common rinsing machine, that is to say the rinsing machine that in a water tank, is provided with agitating device, and the second road rinsing machine both can adopt common rinsing machine, also can adopt the spiral rinsing machine.
The present invention has changed the technology of in the past only wood chip once being cleaned, and wood chip is adopted the secondary cleaning; Wood chip can be with 90% contaminant removal after once cleaning, and after cleaning for the second time, 98% impurity is eliminated, and therefore, the wood-based plate quality made from the wood chip after the cleaning of this technology is good, the class height.And because after this technology broken tradition thought that wood chip comes out from rinsing machine, must enter bin before pump, and, allowing the wood chip of process secondary cleaning directly enter the spiral dewater dehydration through the traditional concept of wood chip pump pump to spiral dewater, wood chip is cleaned in the process of dehydration once more.
Because technology of the present invention has been saved wood chip has been sent into bin before pump, and be pumped to the technology of spiral dewater with the wood chip pump, and therefore greatly saved the energy, total installation of generating capacity has reduced 50%, power consumption reduces by 50%, and this technology also can reduce the wood chip waste more than 90%.Through secondary cleaning, it is complete that it eliminates impurity with wood chip for this technology.Because technology is succinct, equipment is simple, and therefore control is convenient, and fault rate declines to a great extent, and equipment investment reduces, less than original 2/3.
This device structure is succinct, less energy consumption, and cost is low, easily processing.With the installation total amount is 100000m
3/ year washing equipment be example, but every year 30000 tons of water-savings, power saving 1,100,000 degree reduce wood chip loss 2 kilotons, year save 1,180,000 yuan of costs.

(5) specific embodiment:
When concrete enforcement washing equipment of the present invention, can be as shown in Figure 1 and Figure 2, it is made of first rinsing machine, 1, the second rinsing machine 2 and spiral dewater 3.The discharging opening of first rinsing machine 1 is arranged on the charging aperture top of second rinsing machine 2, charging aperture over against second rinsing machine 2, the discharging opening of second rinsing machine 2, be arranged at the charging aperture top of spiral dewater 3, over against spiral dewater 3 charging apertures, in embodiment shown in Figure 1, first rinsing machine 1 and second rinsing machine 2 are common rinsing machine, in embodiment shown in Figure 2, first rinsing machine 1 is common rinsing machine, and second rinsing machine is the spiral rinsing machine.In Fig. 1, embodiment shown in Figure 2, wood chip to be washed is dropped into the charging aperture of first rinsing machine 1, after cleaning for the first time, wood chip comes out from the discharging opening of first rinsing machine 1, directly falls into the charging aperture of second rinsing machine 2.Carrying out the second time cleans; After second rinsing machine 2 cleaned, wood chip came out from second rinsing machine, 2 discharging openings, and the charging aperture that directly falls into spiral dewater 3 dewaters.In Fig. 1, embodiment shown in Figure 2, spiral dewater 3 is identical with the spiral rinsing machine.It is provided with drainage screen cloth 31, and drainage screen cloth 31 is provided with treatment hole 32, and treatment hole 32 is a cylindrical hole, and promptly treatment hole 32 inside and outside sizes are identical.
