Description
The utility model relates to the pulp washing dehydration equipment, more particularly, relates to a kind of unpowered pulp washing dehydration equipment.
The pulp washing dehydration equipment of prior art generally is that its filter mesh is generally 420 μ m (40 order) with power-actuated cylinder thickener, Kamyr filter etc.This kind equipment is not only wanted consumed power, will use a large amount of clear water to wash the paper pulp filter screen simultaneously, therefore all has bigger waste aspect electric energy and the water resource.In addition, these equipment can not adapt to the condition that has a large amount of staple fibres and waste paper composition complexity in the waste paper, be in operation cause mesh to stop up easily or fiber loss excessive, therefore just can't use when above when waste paper fibre shared ratio in paper pulp fiber reaches 50%.
The purpose of this utility model provides a kind of being applicable to and handle high waste paper ratio paper pulp (for example waste paper fibre accounts for more than 50% even can reach 80～100%) in paper pulp fiber, be not easy during operation to cause that mesh stops up, the water consumption during flushing is few and do not need power-actuated unpowered pulp washing dehydration equipment.
The technical solution of the utility model is as follows:
1. unpowered pulp washing dehydration equipment, it has screen pack, paper pulp nozzle, thicken pulp receiving slit and the wastewater trough of band edge frame, wherein, the mesh size of screen pack is 125 μ m (120 order)～250 μ m (60 order), the angle α of screen pack and horizontal plane is 40～60 °, web plate is 1.8～2.5m to the length of lower end from its upper end, and the paper pulp nozzle is in the web plate near the sky on the web plate.
2. the mesh size of above-mentioned screen pack is preferably 149 μ m (100 order)～177 μ m (80 order).
3. the angle α of above-mentioned screen pack and horizontal plane is preferably 50 °.
4. above-mentioned screen pack is preferably 2～2.2m to the length of lower end from its upper end.
5. above-mentioned paper pulp nozzle preferably has a long and narrow paper pulp ejiction opening, and the width of this ejiction opening is 1～4cm, and length is 50～100cm.
6. the width of above-mentioned paper pulp ejiction opening is preferably 2～3cm, and length is preferably 70～80cm.
7. above-mentioned web plate frame preferably has can be by the structure of transversely arranged combination.
8. the twine material of above-mentioned web plate is preferably any in the little nylon of percentage elongation, polyester, copper and the stainless steel.
9. above-mentioned unpowered pulp washing dehydration equipment preferably has an included angle regulator that is used to regulate angle α size.
10. above-mentioned unpowered pulp washing dehydration equipment preferably has a flow regulator that is used to regulate pulp flow.
At length explain the utility model below.
In unpowered pulp washing dehydration equipment of the present utility model, the relative position of screen pack, paper pulp nozzle, thicken pulp receiving slit and wastewater trough and structure thereof can be seen clearly by following accompanying drawing.This equipment is without driven by power, and paper pulp relies on the gravity of self to drop to the upper end that forms the screen pack of 40～60 ° of angles with horizontal plane by the paper pulp nozzle, dips down along the web plate plane then and tiltedly flows.In this process, most of water in rare paper pulp (dry pulp accounts for 1 weight %) (be equivalent to approximately total moisture 70～80%) falls into wastewater trough together with contained impurity by mesh, paper pulp (dry pulp accounts for 3～4 weight %) after concentrating then flows in the thicken pulp receiving slit of screen pack lower end, thereby reaches the purpose of carrying out the pulp washing dehydration without power.
If the aperture of mesh is less than 125 μ m (120 order), then moisture is slow excessively through the speed of web plate, does not reach dehydration and deimpurity requirement.If the aperture of mesh is greater than 250 μ m (60 order), then the loss of paper pulp fiber is too much.Therefore the mesh size is defined as 125～250 μ m, preferred 149 (100 order)～177 μ m (80 order).In addition, if the angle α of web plate and horizontal plane less than 40 °, then the flow velocity of paper pulp is slow excessively, causes that easily mesh stops up.If angle α is greater than 60 °, then the flow velocity of paper pulp is too fast, at this moment by the hypohydration of mesh, does not dewater and deimpurity requirement thereby reach.So angle α is defined as 40～60 °, preferred 50 °.In addition, if web plate from its upper end to the length of lower end less than 1.8m, then dehydration rate is low excessively, do not reach dehydration and deimpurity requirement, if and this length is greater than 2.5m, then dehydration rate is excessive, causes that easily mesh stops up, therefore web plate is defined as 1.8～2.5m, preferred 2.0～2.2m to the length of lower end from its upper end.In addition, the position of paper pulp nozzle is provided with strict restriction, needs only the sky that it is in close web plate upper end in the web plate, so just can guarantee that paper pulp falls into the zone of close upper end in the web plate.In addition, the transverse width of screen pack without limits, it can at random be widened, the frame of web plate is had can be by the structure of transversely arranged combination.This structure that is used to connect can be various, does not need shown in the drawings.For example can be connected by transversely arranged with the web plate of the wide 1m of polylith, long 2m, at this moment the flow path of paper pulp on web plate still is 2m, and the treating capacity of paper pulp widening and increase with web plate.But it should be noted that along with the widening of web plate the number of paper pulp nozzle is also wanted corresponding increase.Preferably make the paper pulp nozzle have a long and narrow ejiction opening, so only need just can make paper pulp cover bigger web plate area with a nozzle.
Compare with traditional pulp washing dehydration equipment, unpowered pulp washing dehydration equipment of the present utility model has following good effect: (1) does not need driven by power; (2) screen pack is not easy to be stopped up and rinse well easily by paper pulp fiber; (3) pulp recovery rate height; (4) install easily, Operation and maintenance are all simple.
