Abstract

The invention discloses a manufacturing device capable of improving the quality of a calcium silicate board blank. The manufacturing device capable of improving the quality of the calcium silicate board blank comprises a slurry box, a driving roller, a reverse roller, a couch roller, a cloth substrate wrapping the driving roller and the reverse roller, a vacuum wind-sucking box, a forming barrel and a coarse cloth adjustment roller, wherein the vacuum wind-sucking box, the forming barrel and the coarse cloth adjustment roller are arranged on the cloth substrate. The manufacturing device is characterized in that a net cage is arranged on the cloth substrate, presses the cloth substrate, and rotates circularly along with the cloth substrate. The manufacturing device combines the advantages of a flowing slurry method and a beater-addition method, and produced products are good in internal quality, flat and smooth in surface and good in quality. In addition, the complex process of a plurality of vacuum pumps of the wind-sucking box and a plurality of net cage trough stirrers is omitted, and the manufacturing device is simple in structure, is convenient to maintain, saves occupied space, is low in energy consumption and lowers the use cost of consumed materials.

Description

A kind of manufacturing installation that improves calcium silicate board slab quality

Technical field

The present invention relates to building materials manufacture, specifically a kind of manufacturing installation that improves calcium silicate board slab quality.

Background technology

At present, the production of calcium silicate board is mainly to copy to follow the example of and slurry flowing process base:

Copy that to follow the example of be that the slurry making is placed in a plurality of cylinder mould grooves, mesh by water strainer cage cloth on cylinder mould surface is discharged the slurry moisture in hopper, be ferreted out and cover on felt, by a vavuum pump, two air-suction trunks see through the moisture of felt spreading mass after felt suction drains, to be sent to forming tube and to be pressed into base by the method for negative pressure suction, this method equipment is complicated, in order to improve production line of output, need to arrange three above cylinder mould hoppers, each hopper needs again the power of 15KW to stir, prevent slurry sediment, power consumption is large, and slurry is copied and is got through the drainage of the cylinder mould cloth mesh on cylinder mould, in slurry, the thinner material elite such as cement partly runs off larger, directly affect the inherent quality of slab, moreover the method cylinder mould immerses in the slurry in stock tank substantially completely, cylinder mould cloth cleans difficulty, easily stop up mesh (referring to Fig. 1).

Slurry flowing process is that the more uniform stream of the slurry in head box is layed onto on felt, adopts three above vavuum pumps the moisture in felt spreading mass to be discharged through the suction of felt fabricbase by the method for negative pressure suction by ten above air-suction trunks.This method is due to felt slurry washiness, and felt is much thick compared with cylinder mould cloth, and separated moisture must adopt three above high-power vacuum pump operations, and power consumption is large (referring to Fig. 2).

Chinese patent CN101612758 discloses a kind of manufacturing process of tile blank of cement pantile, and the cylinder mould of this technique is arranged in the middle of fabricbase depression, keeps in repair very difficult.

Summary of the invention

The object of the invention is to provide a kind of manufacturing installation that improves calcium silicate board slab quality, this device is saved the energy, can improve calcium silicate board slab quality simultaneously.

The technical scheme that realizes the object of the invention is:

A kind of manufacturing installation that improves calcium silicate board slab quality, comprise slurry box, drive roll, fall roller, couch roll, be coated on drive roll and fall fabricbase on roller, be arranged on vacuum air-suction trunk, forming tube, felt dancer rools on fabricbase, unlike the prior art: cylinder mould is set above fabricbase, cylinder mould is pressed on fabricbase, and with fabricbase cycle operation.

The heavy 400-500 kilogram of described cylinder mould.

Advantage of the present invention is:

(1) slab quality is good: owing to combining slurry flowing process and copying the advantage of following the example of, the product inherent quality of producing is good, surfacing, smooth;

(2) apparatus structure is simple: the method has been saved many vavuum pumps, and the complicated technology of a plurality of air-suction trunks and a plurality of cylinder mould hopper agitators is simple in structure, easy to maintenance, and saving equipment takes up an area space;

(3) process energy consumption is low: owing to having adopted the dehydration of slurry flowing process cylinder mould filter-press type, follow the example of blank-making technology and compare with copying, the present invention has removed the energy consumption of a plurality of hopper agitator power from, under same Isoquant comparable copy to follow the example of reduce energy consumption 30%, compare with original slurry flowing process blank-making technology, the present invention reduces by many vavuum pump dehydrations only with a vavuum pump dehydration, with saving energy consumption 33.6% under Isoquant;

(4) reduce consumptive material use cost, the present invention is owing to adopting a cylinder mould press filtration slurry, and cylinder mould is less with felt slurry contact-making surface, is easy to cleaning, more original copying followed the example of blank-making technology and compared, owing to copying, follow the example of blank-making technology and utilize the starching of many cylinder mould grooves, and cylinder mould immerses in stock tank slurry not easy cleaning substantially completely, cylinder mould cloth easily stops up, loss is fast, approximately work and within 24 hours, just need to change cylinder mould cloth, compare cylinder mould cloth of the present invention and can use more than 100 hours, save consumptive material approximately 56%.
