Description

A kind of spike technological compensa tion mechanism of wet production fibre cement product

One, the utility model belongs to New Building Materials, wet production asbestos-cement products shaping equipment field.

Two, prior art situation: present wet production asbestos-cement products shaping equipment, common have cylinder to copy to follow the example of two kinds of blank machine and a stream slurry method of forming blank machines: cylinder is copied and is followed the example of the blank machine structure as shown in Figure 1: be made up of forming tube 1, breast roll 2, abdomen roller 3, net cage 44, net wheel 55, felt 6, carrying roller 7, vacuum tank 10.Operation principle: when power wheel breast roll 2 rotates,, make net wheel 55 rotation synchronously by the transmission of felt 6.And net wheel 55 has half to dive to be immersed in the slip 8 that (slip is by 90% above moisture content, about 8% cement, 2% asbestos are formed), because of the mesh of netting wheel 55 has filterability, so the solid material in the slip is attached on the periphery wire side of net wheel 55 by filtration, the uniform solids of one bed thickness book that will be deposited on the wire side by 55 rotations of net wheel produces liquid level, form base 9 just, base 9 was rotated to when contacting with felt 6 by net wheel 55 originally, because felt 6 is with due to the density contrast of netting, making just, base 9 breaks away from the surface of netting wheel 55 and adhering to felt 6, continue operation through the first base 9 after vacuum tank 10 dehydrations with felt, entering between breast roll 2 and the forming tube 1, is because both density contrasts of existing of felt and forming tube (steel) equally, and base 9 adheres on the forming tube 1 and rolls into certain thickness material base from felt 6 at the beginning of making.The method of filtering by net wheel forms just base and is called cylinder and copies and follow the example of.This method, technology is very ripe, existing more than 100 year history (is seen " concrete and cement products " magazine, published the 1261st phase supplementary issue on August 30th, 2002, be entitled as " a century of international fiber cement products is looked back with Chinese fibre cement product developing direction and inquired into " literary composition) by what doctor Shen Rongxi delivered.The another kind of method equipment of wet production fibre cement product is stream slurry method of forming blank machine, and structural principle is seen Fig. 2: be made up of forming tube 1, breast roll 2, abdomen roller 3, head box 4, pulp flow port 5, felt 6, carrying roller 7, vacuum tank 10.Wherein the base principle of members such as breast roll 2, forming tube 1, felt 6 and cylinder are copied and are followed the example of just the samely, and no longer repeating strolls states.Copy with cylinder that to follow the example of dissimilarity be the formation of base 9 just, flow directly to the upper surface of the felt 6 of uniform motion by the slip in the head box 48 by pulp flow port 5, because felt also has filterability.This slip is flowed directly to filtered the first base that forms on the felt, be called the stream slurry method of forming.These two kinds of fibre cement product shaping equipments are used two kinds of different blank-making methods respectively, but its common ground all is to take wet method pulping process and filtration method blank-making technology.And wet method pulping process and filtration method blank-making technology all have common characteristic, exactly fiber is required to have good adsorption, suspension and loosening property (being called for short " three property ") and process of fiber and non-processing performance material (promptly do not possess granular, the needle-like of " three property ", the solid material of sheet, the granular material that is usually used in producd fibers cement product has cement, flyash, stone flour, Iron Ore Powder etc., the needle-like material has: needle-shaped wollastonite powder, sepiolite etc., sheet material such as mica scale) strict proportioning.The two all is wet method slurrying, blank-making technology key of success.There is a kind of phenomenon at present, to adapt to market in order reducing cost, to adopt and reduce with cotton grade or reduce the amount of cotton and increase the method for non-processing performance material usage, the result runs counter to basic principle, cause non-processing performance material deal and fiber " three property " ability out of proportion, miss to such an extent that it is anti-.

Three, the utility model purpose: at the present producd fibers cement products shaping equipment of existing two kinds of processes, all rely on " three property " of fiber on the technology, can not excess mix non-processing performance material.(mix non-manufacturability material and be called for short " spike ").And " three property " with asbestos fibre ranked first in the existing fiber.But asbestos fibre is poisonous, and harmful human body health belongs to the raw material of forbidding.Moreover, asbestos fibre is a natural products, and a large amount of the employing is frequency domain exhausted at last.So that the sector trend is from putting out.In view of present situation, desire realizes guaranteeing the asbestos consumption of wet method slurrying, blank-making technology requirement, and mixing the few asbestos-cement products of non-processing performance manufacture of materials with the penalty method excess is purpose.

Four, realize that the technical solution of the utility model is to copy by cylinder to follow the example of blank machine and the existing mature technology structure of stream slurry method of forming blank machine, as shown in Figure 3, above felt 6 between the carrying roller 7, installs one or more groups spike compensation mechanism at abdomen roller 3.The spike compensation mechanism is made up of spike recombiner assembly 11, spike induction system 12 and continuous flow rate device assembly 13.Wherein spike recombiner assembly 11 is made up of charging aperture 14, charging baffle plate 15, baffle plate adjusting bracket 16, stirring wheel sheet 17, stirring wheel shaft 18, discharging opening 19, casing 20, frame 21, power input wheel 22 as Fig. 4, shown in Figure 5.Charging baffle plate 15 is formed for multi-sheet structure.Connect with baffle plate adjusting bracket 16 with regulating bolt.The mounting structure of charging baffle plate 15 can also directly be fixedly mounted on the inwall of casing 20.Stirring wheel shaft 18 two ends is installed on the casing 20 by shield bearing.The physique structure of stirring wheel sheet 17 is the whole sheet of rectangle, prolongs the axial integral solder that stirs wheel shaft 18 and installs.The physique structure of stirring wheel sheet 17 is installed and also can be made up of some monolithics, prolongs axially to be angle and to be interrupted on the periphery wall that welding is installed in stirring wheel shaft 18.The physique structure of stirring wheel sheet 17 can also be by the isometric little rod member of some pins, clavate shape, radially to gather welded and installed on the periphery wall that stirs wheel shaft 18.Discharging opening 19 shapes can be rectangles, also can be irregular rectangles.Spike induction system 12 is made up of conveyer assembly 23, charging aperture 24 and conveyance conduit 25 as shown in Figure 6.The structure of conveyer assembly 23 is identical with existing centrifugal fan structure.Continuous flow rate device assembly 13 is made up of hopper 26, material-feeding shaft 27, feed cylinder 28, discharging opening 29, frame 30, power input wheel 31 as shown in Figure 7.The physique structure of material-feeding shaft 27 is a screw rod axle construction, shield bearing is installed at the helical axis two ends is connected with feed cylinder 28.Feed cylinder 28 is mounted to one with hopper 26 and frame 30 for the welding combination.

Five, good effect of the present utility model

1, this reality has novel employing compensation to mix method, avoids wet method slurrying, base prior art processes are mixed non-processing performance material to excess restriction.Can realize that excess mixes the few asbestos-cement products of non-processing performance manufacture of materials.

2, intervention of the present utility model can obviously improve the unit-hour output of prior art equipment and reduce the product material cost, and reduce and produce worker's consumption.

3, the utility model is got involved the goods of producing, and surface roughness is improved significantly, and has improved the products appearance quality.
