Description

Exempt to dry comminutor

Technical field

It the utility model is related to and be related to Granulation Equipments, and in particular to one kind is exempted to dry comminutor.

Background technology

Generally particle will be made after raw material tabletting using tablet press machine using comminutor in sheet semi-finished product by existing comminutor Shape, and the little particle for being unsatisfactory for requirement and caused powder are recycled in tablet press machine and be granulated again again, but this granulation During, because the little particle intensity after tabletting and crushing is higher, the product being granulated not successfully is put into tablet press machine two again During secondary tabletting, it is difficult to combined closely with other raw materials, so other pelletizing additives must be added to aid in being granulated thereto, so And the increase of pelletizing additives can cause product purity to reduce, simultaneously because the use of pelletizing additives, it is necessary to increase by a drying Process, reduce production efficiency.

Utility model content

Main purpose of the present utility model is to provide one kind and exempts to dry comminutor, it is intended to solves existing comminutor granulation process In need drying the problem of.

To achieve the above object, the utility model provide one kind exempt from dry comminutor, including be sequentially connected mixing device, Drawing-in device, tablet press machine, crushed machine, pelletizing machine and vibratory sieve；

The drying comminutor of exempting from also includes lapping device, the outlet of the charging aperture of the lapping device and the vibratory sieve It is connected；Also include

Material-returning device, the material-returning device are corresponding with the lapping device and the drawing-in device.

Preferably, the material-returning device is elevator bucket.

Preferably, the tablet press machine is to roller tablet press.

The technical scheme of the present embodiment, can by setting lapping device to grind the below standard Small granular product of size Effectively to avoid influenceing secondary tabletting effect because indivedual high rigidity crystallizations be present, it is possible to reduce or exempt making for pelletizing additives With on the one hand improving the purity of product, on the other hand also without being dried, help to reduce the production time, improve life Produce efficiency.

In addition, and it can not be managed in the utility model such as relating to the description of " first ", " second " etc. is only used for describing purpose Solve to indicate or implying its relative importance or the implicit quantity for indicating indicated technical characteristic.Thus, define " the One ", at least one this feature can be expressed or be implicitly included to the feature of " second ".It is " more in description of the present utility model It is individual " it is meant that at least two, such as two, three etc., unless otherwise specifically defined.

In the utility model, unless otherwise clearly defined and limited, term " connection ", " fixation " etc. should do broad sense reason Solution, for example, " fixation " can be fixedly connected or be detachably connected, or integrally；Can mechanically connect, also may be used Be electrical connection；Can be joined directly together, can also be indirectly connected by intermediary, can be the connection of two element internals Or the interaction relationship of two elements, limited unless otherwise clear and definite.For the ordinary skill in the art, can be with Concrete meaning of the above-mentioned term in the utility model is understood as the case may be.

In addition, the technical scheme between each embodiment of the utility model can be combined with each other, but must be with ability Domain those of ordinary skill can be implemented as basis, will be understood that when the combination appearance of technical scheme is conflicting or can not realize The combination of this technical scheme is not present, also not within the protection domain of the requires of the utility model.

The utility model proposes a kind of high-purity comminutor.

Fig. 1 is refer to, in the embodiment of the utility model one, the high-purity comminutor includes mixing device 10, feeding fills Put 20, tablet press machine 30, crushed machine 40, pelletizing machine 50, vibratory sieve 60, material-returning device 70 and lapping device 80.

Wherein mixing device 10 includes batch mixer, during use, adds raw materials into the mixing tank for coating colors of batch mixer, and mixed Expect to be well mixed in device 10.In the present embodiment exemplified by processing zinc sulfate particle, when specifically used, zinc sulfate raw material is added In mixing tank for coating colors, and stirred using batch mixer.

Drawing-in device 20 includes charging bucket elevator and feeding machine, wherein charging bucket elevator is connected with mixing device 10, mixes Raw material afterwards is added in feeding machine by feeding bucket elevator.During practical operation, batch mixer can be mixed by automatic charging equipment After raw material added to charging bucket elevator in, can also manually using the instruments such as scoop, rake by batch mixer mix finish Raw material afterwards is added in charging bucket elevator.

The drive device of feeding machine is a frequency control motor, and the change of a power 7.5KW has been used in the present embodiment Frequency modulation speed motor, can be according to production efficiency reasonable adjusting rate of feeding.

Tablet press machine 30 in the present embodiment is that roller tablet press, the hydraulic fluid pressure of tablet press machine 30 are disposed as being less than 12MPa, in the present embodiment, the discharging opening of drawing-in device 20 is connected to the charging aperture of tablet press machine 30.

The discharging opening of tablet press machine 31 is provided with crushed machine 40 and pelletizing machine 50.Wherein crushed machine 40 is mainly used in that sheet will be pressed into Raw material be broken into the particle of specified size, and pelletizing machine 50 then adjusts the product particle that the particle of crushed machine 40 finishes by filter screen Shapes and sizes, preset value is respectively less than by the product particle of pelletizing machine 50, the preset value for select pelletizing machine 50 filter Net meshe size, for example, the filter screen mesh chi of zinc sulfate particle, then pelletizing machine 50 of the planned production particle diameter less than 4 millimeters It is very little to should be 4 millimeters.

Further, it is passed to by the product after the whole grain of pelletizing machine 50 on vibratory sieve 60, because crushed machine 40 is broken A large amount of small sized particles can be produced during grain, and pelletizing machine 50 can also produce more dust during whole grain.This implementation The product for meeting to require is sifted out in example, and remaining products material is transferred to lapping device 80.

Particle size is less than the products material of preset value after being ground by lapping device 80, is lifted by material-returning device 70 To drawing-in device 20, and drawing-in device 20 is added, accordingly, the process that products material is added into drawing-in device 20 can be with It is accomplished manually, can also be directly toppled over thereto using plant equipment.Material-returning device 70 in the present embodiment is specially a lifting Bucket, its position is corresponding with lapping device 80 and drawing-in device 20, and the below standard product of the size for vibratory sieve 60 to be sifted out is former Material rejoins drawing-in device 20. after being ground by lapping device 80

The technical scheme of the present embodiment, can be with by setting lapping device 80 to grind below standard Small granular product Effectively avoid influenceing secondary tabletting effect because indivedual high rigidity crystallizations be present, it is possible to reduce or exempt making for pelletizing additives With on the one hand improving the purity of product, on the other hand also without being dried, help to reduce the production time, improve life Produce efficiency.

Preferred embodiment of the present utility model is the foregoing is only, not thereby limits the scope of the claims of the present utility model, Every equivalent structure transformation under design of the present utility model, made using the utility model specification and accompanying drawing content, or Directly/be used in other related technical areas indirectly and be included in scope of patent protection of the present utility model.
