Description
Technical field
The present invention relates to the fibre cement product technical field, specifically is that a kind of fibre cement product is copied to get and converted paste-making method and equipment in the making sheet.
Background technology
When existing fiber cement board materials for wall is produced, copy get making sheet before, need prepared slurry diluted and be used further to produce, general Processes and apparatus as shown in Figure 1.
Underflow from the dnockout pot is stored in the underflow jar, again the slurry of underflow jar is pumped into and convert in the slurry jar, by converting the slurry jar sensor of upward installing underflow weight as can be known, the ingredients concentration of known dnockout pot, so added the water of some by water inlet pipe to converting the slurry that the slurry jar obtains technological requirement concentration, pump into the slurry can from converting the slurry jar again, for the production of.Batching is step, in order to produce continuously, to design two and converts slurry jar, and the using and the reserved jar are installed a radar level gauge converting slurry, when material level is lower than certain value, represent that this jar material uses up, and setting program autocratic another is automatically converted the slurry jar and sent and starch to slurry can.But in normal productive process, when production line need be adjusted pulp density, need adjust concentration when slurry preparation next time, inconvenience is adjusted immediately, causes the not smooth and inconvenient of production.
Summary of the invention
The purpose of this invention is to provide a kind of flow process fibre cement product simple, easy and simple to handle copies to get and converts paste-making method and equipment in the making sheet.
The paste-making method of converting of the present invention is: by being installed in the liquid level of the radar level gauge J control slurry can on the slurry can, and the aperture of valve in the aperture by being installed in valve in the flowmeter control feed pipe on feed pipe and the water inlet pipe and the water inlet pipe, and then control slurry can material level and concentration.
The slurry equipment of converting of the present invention comprises the underflow jar, slurry can, feed pipe, water inlet pipe, feed pipe connects underflow jar and slurry can, water inlet pipe connects slurry can, it is characterized in that feed pipe be provided with the valve overflow tank to slurry can valve and overflow tank to slurry can proportion adjustable valve and electromagnetic flowmeter I, water inlet pipe is provided with water inlet pipe proportion adjustable valve and electromagnetic flowmeter II, radar level gauge is set in the slurry can, one overflow tank is set between underflow jar and feed pipe, feed pipe one end connects overflow tank, the upper and lower of underflow jar connects overflow tanks by two pipelines respectively, and the slurry of underflow jar is pumped into overflow tank.
Open an overfall at overflow tank, guaranteed that the material level of slurry can is in certain limit.
By regulating the flow that overflow tank to the big I of slurry can proportion adjustable valve and water inlet pipe proportion adjustable valve is learnt feed pipe flowmeter I and water inlet pipe flowmeter II, by flow-rate ratio and then draw the concentration of slurry can.
Sizing process and the equipment converted of the present invention does not need to convert slurry jar, saves two and converts slurry jar and relevant auxiliary equipment and control element, and easy and simple to handle, control is accurate, reduces equipment investment greatly and reduces production costs.
Description of drawings
Fig. 1 is that existing fibre cement product is copied to get and converted sizing process and equipment in the making sheet.
Fig. 2 is that fibre cement product of the present invention is copied to get and converted paste-making method and equipment in the making sheet.
Among Fig. 1: 1-underflow jar, 2-feed pipe, 3-are converted slurry jar LOAD CELLS, and 4-converts slurry jar I, and 5-converts slurry jar II, and 6-water inlet pipe, 7-slurry can, 8-slurry can radar level gauge, 9-are converted slurry jar radar level gauge I, and 10-converts slurry jar radar level gauge II.
Among Fig. 2: A-underflow jar, B-overflow tank, C-overflow tank are to the slurry can valve, and the D-overflow tank is to slurry can proportion adjustable valve, E-electromagnetic flowmeter I, F-water inlet pipe proportion adjustable valve, G-electromagnetic flowmeter II, H-slurry can, the I-overfall, J-slurry can radar level gauge, K-feed pipe, M-water inlet pipe.
The specific embodiment
As shown in Figure 2, the slurry equipment of converting of the present invention comprises underflow jar A, slurry can H, overflow tank B, feed pipe K, water inlet pipe M etc., feed pipe connects overflow tank B and slurry can H, water inlet pipe M connects slurry can H, feed pipe be provided with the valve overflow tank to slurry can valve C and overflow tank to slurry can proportion adjustable valve D and electromagnetic flowmeter I E, water inlet pipe is provided with water inlet pipe proportion adjustable valve F and electromagnetic flowmeter II G, radar level gauge J is set among the slurry can H, one overflow tank B is set between underflow jar A and feed pipe, feed pipe one end connects overflow tank B, the upper and lower of underflow jar A connects overflow tank B by two pipelines respectively, opens an overfall I at overflow tank.Wherein proportion adjustable valve, electromagnetic flowmeter, radar level gauge etc. are existing apparatus.
By regulating the flow that overflow tank to the big I of slurry can proportion adjustable valve D and water inlet pipe proportion adjustable valve F is learnt feed pipe flowmeter I E and water inlet pipe flowmeter II G, by flow-rate ratio and then draw the concentration of slurry can.
Set slurry can material level scope by radar level gauge J in the slurry can, when the slurry can material level is lower than when setting low value, overflow tank is opened ratio to slurry can proportion adjustable valve D and water inlet pipe proportion adjustable valve F to be increased, and is in feeding and send water state; When the material level of slurry can is higher than when setting high value, overflow tank is opened the ratio reduction to slurry can proportion adjustable valve D and water inlet pipe proportion adjustable valve F.One overflow tank is installed before feed pipe, the slurry that is about to underflow jar A pumps into overflow tank B, the slurry of overflow tank B enters slurry can H by feed pipe, overflow tank B leaves an overfall I, the slurry of overflow flows into underflow jar A, guarantee overflow tank not fracture and liquid level remain on sustained height, guaranteed the stability of flow of feed pipe.
