Description

The guipure filtering type moves net cage

Technical field

The utility model technology relates to the equipment of producd fibers cement floor tile and fiber calcium silicate board, particularly wherein is used for filtering and copying the net cage of feeding slurry.

Background technology

The method of domestic and international existing producd fibers cement floor tile and fiber calcium silicate board mainly contains cylinder and copies and follow the example of and slurry flowing process.It is similar that cylinder is copied the principle of following the example of with figure one, and figure one copies for traditional asbestos-cement products cylinder and follows the example of the production process schematic diagram.The slip that modulates flow in the net cage 12 by conveyer trough 25, slurry level is flooded to the position, 3/4 left and right sides of net wheel 26 diameters, net wheel outer wrap has the Inside and outside network of certain order number, net wheel top is provided with couch roll 6 and presses volt woollen blanket 3 to contact with the net wheel, during operation, breast roll 2 rotates and drives woollen blanket 3 operations, couch roll 6 passive rotations drive 26 rotations of net wheel simultaneously, slip filters by net wheel 26 under the effect of pressure reduction, it is outer online that the bed of material that produces is attached to the net wheel, because net is taken turns genus polyporus and can be seen through air, and couch roll, denser between woollen blanket and the bed of material, do not have air to pass through, so the easier disengaging net wheel of the bed of material adheres on the woollen blanket, thin bonding layer just continuously is delivered on the woollen blanket.Agitator 27 is used for preventing the slip precipitation, after heavier sandstone foreign material sink at the bottom of the case, regularly removes by the discharge pipe 13 of base plate.The bed of material through vacuum tank 5 dehydration after, be wound on the forming tube 1, shut down wet base from forming tube after meeting the requirements of thickness, be processed into various products through next procedure.Cylinder is copied the shortcoming of following the example of existence, can only adapt to the thin material of thin pulp, and it is very thin that single cylinder is copied the bed of material of getting, need a plurality of cylinders for improving output, backwater concentration is high, and fibre length is had requirement, fiber is two-dimensional arrangements, and " punching material " phenomenon is difficult to solve, and the forward fracture resistence force of goods is difficult for guaranteeing, output is on the low side, cost is high, and cylinder copies that to follow the example of manufacturing technique requirent strict, and influence factor is many, fault is many, is difficult for grasping.

China Patent No. 89203043.7 provides a kind of equipment---head box of producing asbestos-cement products with slurry flowing process, the production technology of slurry flowing process as shown in Figure 2, its principle is that agitator 27 and dividing plate are housed in head box, when slip reaches certain liquid level in head box, by horizontal cloth pulpboard and the stream pulpboard 29 that the tilts first bed of material of formation to the woollen blanket 3 that naturally trickle, just the bed of material is through a plurality of vacuum tank 5 forced dehydrations, be wound on the forming tube 1, shut down wet base from forming tube after meeting the requirements of thickness, be processed into various products through next procedure.The shortcoming that slurry flowing process exists is, product surface is coarse, and bed of material thickness is wayward, causes slab thickness inhomogeneous, and output is on the low side, and cost is high.
