Background technique

When cell positive material processing, spray drying device to be used to carry out drying and processing, current processing to slurry In the process, discovery has the modular spray nozzle clogging that slurry will be mounted on spray drying tank upper end in use, therefore, For nozzle clearing, prolonged maintenance shut-downs is needed to repair, this will be expended for a long time.

Summary of the invention

In view of the technical drawbacks of the prior art, it is an object of the present invention to provide a kind of cell positive materials to prepare Use spray drying system.

The technical solution adopted to achieve the purpose of the present invention is:

A kind of cell positive material preparation spray drying system, including it is spray-dried tank, have at the top of the spray drying tank The opening of vertical structure, the outside of the opening are equipped with two guide grooves, are equipped with the first spray drying nozzle between the guide groove Module and the second spray drying nozzle module, the first spray drying nozzle module and the second spray drying nozzle module Outside be separately connected driving mechanism, with drive it is described first spray drying nozzle module and second spray drying nozzle module It moves linearly along guide groove, to seal cooperation with the opening or separate, to realize that quick-replaceable is spray-dried nozzle.

Wherein, the structure of the first spray drying nozzle module and the second spray drying nozzle module is identical, wraps Include the barrel that one cooperates with the opening and the spray drying nozzle being mounted in the barrel.

Wherein, the sliding block with guide groove cooperation is fixed on the outside of the barrel.

Wherein, the bottom of the barrel is provided with magnetic seal ring, to inhale with the upper end iron-based material of the opening Attached sealed connection.

Wherein, the driving mechanism is cylinder.

The present invention pass through more than technical solution so that spray drying tank opening can with it is described first spray drying nozzle Module and the second spray drying nozzle cooperation, realize sealing cooperation, or separation, to realize the driving using driving mechanism It realizes quick-replaceable, solves in the prior art for nozzle clearing, prolonged maintenance shut-downs is needed to repair, this will be expended very Prolonged problem.

Detailed description of the invention

Fig. 2, which is shown, overlooks the schematic diagram that lower spray drying nozzle is mounted on guide rail；

Fig. 3 show the schematic side view that spray drying nozzle is mounted on guide rail.

Specific embodiment

The present invention is described in further detail below in conjunction with the drawings and specific embodiments.It should be appreciated that described herein Specific embodiment be only used to explain the present invention, be not intended to limit the present invention.

As shown in Figure 1-3, a kind of cell positive material preparation spray drying system of the present invention, including spray drying tank 17, it is described to be spray-dried at the top of tank the opening 1 for having vertical structure, which is characterized in that the outside of the opening passes through bracket 16 Equipped with two guide grooves 2, the first spray drying nozzle module 3 and the second spray drying nozzle module are installed between the guide groove 4, it is separately connected driving mechanism and includes on the outside of the first spray drying nozzle module and the second spray drying nozzle module First driving mechanism 9 and the second driving mechanism 10, to drive the first spray drying nozzle module and second spraying dry Dry nozzle module moves linearly along guide groove, to cooperate or separate with 1 sealing of opening, to realize that quick-replaceable is spray-dried Nozzle.

Wherein, the structure of the first spray drying nozzle module and the second spray drying nozzle module is identical, wraps Include the barrel that one cooperates with the opening 1 and the spray drying nozzle 5 being mounted in the barrel.The spray Mist dry nozzle 5 include superheated steam inlet tube 6, slurry and air mixing inlet tube 7, expect and air mixing inlet tube 7 it is upper One tee tube 8 of end connection, to introduce slurry and compressed air respectively.The barrel is consistent with the shape of opening, diameter It is identical.

Wherein, the sliding block 13 cooperated with the guide groove 14 is fixed on the outside of the barrel, in this way can be described The linear movement of first spray drying nozzle module 3 and the second spray drying nozzle module 4.

Specifically, the sliding block is connected and fixed by screw 15 and the barrel of spray drying nozzle module.

Wherein, the bottom of the barrel is provided with magnetic seal ring 6, with the upper end iron-based material with the opening 1 Absorption is tightly connected.The magnetic seal ring 6 is that soft magnetic materials makes to be formed, surfacing, the upper end iron with the opening 1 The upper surface of sill is now to be engaged, and by magnetic-adsorption, realizes sealing, can prevent the material spray of the tank body entered Out.

Wherein, the driving mechanism is cylinder, of courses, is also possible to electric cylinder or hydraulic cylinder or other straight line drivings Structure, it is specific unlimited.Driving mechanism passes through drive rod 12 and the first spray drying nozzle module 3 and the second spray drying nozzle mould The barrel of block 4 is fixedly connected, and realizes the driving first spray drying nozzle module 3 and the second spray drying nozzle module 4 is mobile.

Wherein, the driving mechanism is mounted in mechanism fixed plate 11, and the upper surface of the mechanism fixed plate and guide groove is solid It is fixed, such as weld or be bolted fixation.

When such as needing replacing nozzle, inlet valve on the feed pipe of first temporary close nozzle, then two driving mechanisms are synchronous Movement, is moved to the left, and the nozzle in left side is mobile, is separated with opening, nozzle movement and the opening sealing cooperation on right side, and realization is fast Speed replacement nozzle purpose, open later inlet valve can normal operation, can be completed within several seconds in entire replacement process.

The present invention pass through more than technical solution so that spray drying tank opening can with it is described first spray drying nozzle Module and the second spray drying nozzle cooperation, realize sealing cooperation, or separation, to realize the driving using driving mechanism It realizes quick-replaceable, solves in the prior art for nozzle clearing, prolonged maintenance shut-downs is needed to repair, this will be expended very Prolonged problem.

The above is only a preferred embodiment of the present invention, it is noted that for the common skill of the art For art personnel, various improvements and modifications may be made without departing from the principle of the present invention, these improvements and modifications Also it should be regarded as protection scope of the present invention.
