Description

A kind of adding set of fluidized bed

Technical field

The utility model relates to salt manufacturing fields, more particularly, to a kind of adding set of fluidized bed.

Background technique

Salt manufacturing production in product salt additive addition generally use drying bed before add or drying bed after add, Addition product mix is uniform before bed, but powder salt product additive level is often 2 ~ 3 times of finished product salt, cannot function as qualified products It sells, adding technology needs to increase mixing arrangement after bed, and after salt amount is greater than 80t/h, domestic existing mixing apparatus can not Meet the requirement being mixed thoroughly, there are larger hidden danger of quality.

Utility model content

Technical problem to be solved by the utility model is: overcoming the deficiencies of the prior art and provide one kind both can guarantee finished product The content of additive in salt, and the adding set of the fluidized bed of the content of additive in powder salt can be reduced.

The technical scheme adopted by the utility model to solve the technical problem is as follows: a kind of adding set of fluidized bed, including Fluidized bed and nozzle, the fluidized bed include inlet port and outlet port, the nozzle include jet pipe, air intlet, additive into Mouth and jet hole, one end of the jet pipe are equipped with air intlet, and the other end is equipped with jet hole, and the additive inlet port is located at close One end of air intlet, perpendicular to jet pipe, nozzle is mounted on discharge port top.

Additive nozzle with compressed air makes additive form the droplet of high speed dispersion under compressed air drive, It is sprayed in drying bed, reduces the fogging degree of additive, while expanding the spray area of additive again.

Specifically, the nozzle is mounted on above discharge port at the position 2500mm ~ 3500mm.In the present embodiment, it will spray Mouth is mounted on above discharge port at 3000mm.

Specifically, the nozzle is mounted at the top of discharge port, nozzle is vertical with top.Nozzle is mounted at the top of discharge port tiltedly The middle part in face, it is vertical with top bevel, can the salt to lower section preferably sprayed, in the present embodiment, the inclined-plane with go out Plate is in 120 ° on the outside of material mouth.

Specifically, the fluidized bed further includes hot wind area and cold wind area, the cold wind area is close to discharge port.Salt is from feed inlet Into, first pass through hot wind area, salt made to become fluidized state under the drive of hot wind, the salt of fluidized state can preferably with addition Agent mixing, cold wind area is equipped in front of discharge port, is cooled down to the salt of high temperature drying.Simultaneously hot wind area include hot wind inlet and Hot-blast outlet, cold wind area include cold wind import and cold wind outlet, and salt enters hot wind area, has sub-fraction salt and become powder salt, from Hot-blast outlet discharge, is the first powder salt, and remaining salt enters cold wind area, at this moment also has sub-fraction salt and become powder salt, and It is mixed with additive, can export and be discharged from cold wind, is the second powder salt；First powder salt is mixed with the second powder salt, becomes additive and contains Measure qualified powder salt.

Specifically, the wind pressure in the hot wind area is greater than the wind pressure in cold wind area.Because the wind pressure in hot wind area is greater than cold wind area Wind pressure can promote salt mobile from the area Xiang Lengfeng, hot wind area.

The utility model has the beneficial effects that

By the change of nozzle itself and the determination of installation site, fogging degree when spraying additive is reduced and is covered Area increase, additive will not be blown away, while can guarantee that the additive level in finished product salt is up to standard；By adding The powder salt in agent region, the too high levels of additive in powder salt, and export and be discharged from cold wind, by the powder salt and heat of cold wind outlet discharge The powder salt without additive of wind outlet discharge is mixed, up to standard with the content for reaching additive in powder salt.

Detailed description of the invention

Fig. 1-is the schematic device of nozzle in the utility model；

Fig. 2-is the utility model schematic cross-section.

In figure: 1-jet hole, 2-jet pipes, 3-additive inlet ports, 4-air intlets, 5-hot wind inlets, 6-it is interior plus Heat pipe heat, 7-cooling tube groups, 8-cold wind imports, 9-discharge ports, 10-discharge valves, 11-nozzles, the outlet of 12-cold wind, 13-hot-blast outlets, 14-feed inlets, 120 ° of α-.

Specific embodiment

The following is a further explanation of the present invention with reference to the accompanying drawings and embodiments.

Referring to Figures 1 and 2: a kind of adding set of fluidized bed, including fluidized bed and nozzle 11, the fluidized bed include into Material mouth 14 and discharge port 9, nozzle include jet pipe 2, air intlet 4, additive inlet port 3 and jet hole 1, and one end of jet pipe is equipped with sky Gas import, the other end are equipped with jet hole, and additive inlet port is located at close to one end of air intlet, perpendicular to jet pipe, nozzle installation On discharge port top.

It in the present embodiment, is in bevel structure, the inclined-plane and composition above discharge port at nozzle is mounted on above discharge port The outside plate of discharge port forms angle, and angle α, α are 120 °, and nozzle is vertically installed downwards with inclined-plane, apart from discharge port 3000mm, the direction that jet hole comes towards material.

Fluidized bed further includes hot wind area and cold wind area, and hot wind area includes hot wind inlet 5, hot-blast outlet 13 and interior heating tube group 6, cold wind area includes cold wind import 8, cold wind outlet 12 and cooling tube group 7.Feed inlet pours into not additivated salt, and salt enters In fluidized bed, lower section has hot wind to blow to salt, and the smaller salt of particle is known as powder salt, and powder salt is blown to hot-blast outlet；Hot wind area Wind pressure is big, and the wind pressure in cold wind area is small, using leeway, salt is made to flow to cooling zone from hot wind area, salt flows to after hot wind area boils Cooling zone, wind pass into cooling pipe from cold wind import and blow to salt, carry out cooling treatment to salt, and cold toward entering at nozzle But the salt in area is added the addition of agent, exports at this point, the powder salt for also having sub-fraction can be blown to cold wind, and this part The content of additive is higher in powder salt, so can mix the powder salt of this part with the powder salt that hot-blast outlet comes out, to protect The additive level demonstrate,proved in powder salt is up to standard.

When salt is after additive is added in cooling zone, discharge port can be entered, discharge port has a discharge valve 10, and discharge valve controls The on and off of discharge port.The addition of fixed proportion is arranged using the weighing belt flow of discharge port as input signal in entire production process Amount completes the addition of additive by automatic control system.
