Embodiment

The detail and the work that propose below in conjunction with description of drawings the present invention of specification sheets

Device for preparing large-scale lime cream mainly comprises: respiratory organ 1, feed-pipe 2, level gage 3, discharge flapper 4, lime warehouse 5, tracheae 6, vibrating motor 7, shaking device 8, guiding valve 9, soft connection 10, weight feed machine 11, nitrated machine 12, stirrer 13, dissolving tank 14, ultrasonic level gage 15, volume pump 16, gear 17, conventional seals 18, stir shaft 19, rake teeth 20, long cavate reaction chamber 21, discontinuous band intersects pusher duplex cleavage reaction blade 22, mechanical seal 23, inlet pipe 24, tremie pipe 25, endless spiral axle 26, for powder machine inlet capable 27, upper bracket 28, for powder variable-frequency motor 29, broken sieve 30, band air supported head 31, vibrator 32, weir divider 34 and housing.

The present invention is so concrete enforcement: the lime powder is delivered to lime warehouse 5 by transport pipe with the lime powder by special-purpose tank car.Dedusting respiratory organ 1 is equipped with on feed bin top, guarantee that powder can successfully enter feed bin and environment do not caused secondary pollution, two blocking rotary type level gages 3 are housed on the feed bin sidewall, can report the minimum reserves and the highest reserves of powder exactly, thereby whether the prompting staff carry powder in feed bin.

In order to prevent that the lime powder from hardening in feed bin, influence the accurate supply of powder, the conical part below feed bin lime warehouse 5 adds two vibration motor vibrating motors 7, and Vibration on Start-up motor 7 during blanking makes powder be difficult for being bonded on the bulkhead.Also adorn in the bottom of feed bin in addition and have the sieving formula feed bin shaking device 8 that floats, thereby make powder can waltz through guiding valve 9, soft connection 10 enters powder weight feed machine 11.

Shaking device 8 is installed in lime warehouse 5 bottoms, and band air supported head 31, broken sieve 30, vibrator 32 have effectively prevented to make the storage bin blanking smooth and easy owing to hardening that lime is piled up, extruding causes.

Weight feed machine 11 is installed in the bottom of guiding valve 9, soft connection 10, on the upper bracket 28 of nitrated machine 12, lime enters into for powder machine inlet capable 27 by guiding valve 9, soft connection 10, the powder variable-frequency motor 29 that supplies of housing control drives endless spiral axles 26 pusher quantitatively supplying powders, improve for the powder precision, satisfy the requirement of weight feed as required, the lime powder enters in the nitrated machine 12 through tremie pipe 25.

Nitrated machine 12 is installed in the bottom of weight feed machine 11, weight feed machine 11 enters the lime powder in the long cavate reaction chamber 21 of nitrated machine 12 through tremie pipe 25, water-in water inlet simultaneously, motor reducer driven gear 17, stir shaft 19, discontinuous band on the stir shaft 19 intersect pusher duplex cleavage reaction blade 22, rake teeth 20 carry out nitrated, dissolving is stirred, a side of middle long cavate reaction chamber 21 is conventional seals 18, one side is mechanical seal 23, can not be nitrated, dissolved dregs precipitation is by the bottom of long cavate reaction chamber 21, regularly by slag remover 35 discharges.

The lime powder enters in the dissolving tank 14 through the tremie pipe of nitrated machine 12, and the stirrer 13 that is installed in top stirs, and guarantees that groove sodalime emulsion keeps dissolved state; Ultrasonic level gage 15 on the dissolving tank 14 detects the height of liquid levels, begins water inlet, feed during to low liquid level, intakes during two position, feed stops.Volume pump with the lime slurry that configures in 16 dissolving tanks 14 as required pump of constant delivery type deliver to the user.By these structures, make this device for preparing large-scale lime cream have preparation emulsion precision height, level of automation height, no dust pollution, for powder precision height, advantage such as preparative capacibility is strong.
