Bulk, for transmitting device 4 for transporting graininess dry ice to preforming device 3, transmitting device 4 is set to particle device 2 and tabletting
Between device 3, wherein one end of transmitting device 4 is located at below the discharge port of particle device 2, and the other end is located at preforming device 3
Feed inlet above.
Liquid CO 2 in storage device 1 is delivered to particle device 2 by process pipe 5, and particle device 2 is by liquid
Carbon dioxide conversion is on output to transmitting device 4, graininess dry ice is transported pressure extremely again by transmitting device 4 after graininess dry ice
Graininess dry ice is compressed into blocky dry ice and by its discharge port output by sheet devices 3, preforming device 3.
Further, it in order to improve the output control to graininess dry ice, is provided on process pipe 5 for controlling
The logical switch valve 6 of flow of liquid carbon dioxide can be from the life of charging source control control graininess dry ice by controlling the switch valve 6
Yield.
Further, the setting height of storage device 1, particle device 2, transmitting device 4 and preforming device 3 successively drops
It is low, in this way, making liquid CO 2 using gravity during using dry ice production system production bulk dry ice of the invention
By the transport of storage device 1 to particle device 2, make graininess dry ice by the output of particle device 2 to transmitting device 4, and makes particle
Shape dry ice is exported by transmitting device 4 to preforming device 3, is saved design cost, is reduced the fortune of dry ice production system of the invention
Make energy consumption.
Further, storage device 1 is one of vacuum tank, spherical tank and low-temperature storage tank, wherein storage device 1
Enlarged storage can be realized using low-temperature storage tank, land occupation is few, and structure is simple, further decreases storage cost, and reduce construction
Cost.
Further, particle device 2 uses carbon dioxide ice maker, such as the granular dry ices manufacturing machine of model KBM-300.
Further, preforming device 3 presses ice maker using pressure ice maker, such as not Lossen of model FCP-03K.
Further, transmitting device 4 uses transmission belt or chain and pan conveyor, as model BL400 dissepiment is defeated
Send machine.
Embodiment two:
It please refers to shown in Fig. 2, is the technique for going the production method of dry ice of flash removed in embodiment for phone housing
Step schematic diagram.
The present embodiment provides a kind of production methods of dry ice that flash removed is removed for phone housing comprising following main step
It is rapid: stock, the first molding and second of molding.
In material preparation step, using liquid CO 2 required for needing to prepare to produce, liquid CO 2 is stored in
In storage device 1, storage device 1 be one of vacuum tank and spherical tank, storage device 1 can also be used relative to vacuum tank with
And spherical tank has pressure store is low, safety is good low-temperature storage tank, and enlarged storage can be realized using low-temperature storage tank, it accounts for
Ground lacks, and structure is simple, further decreases storage cost, and reducing the construction costs.
Production method of the invention mainly uses liquid CO 2 as raw material, of course, can also be used gaseous two
Carbonoxide is corresponding as raw material, needs to be added in the method for the invention gaseous carbon dioxide is depressed into liquid dioxy
Change the processing step of carbon, for example, gaseous carbon dioxide is liquefied as liquid carbon dioxide, it is then that liquid carbon dioxide is defeated
It send to storage device 1.
In first time forming step, liquid CO 2 is delivered in particle device 2 by storage device 1 and is converted to particle
Shape dry ice, wherein particle device 2 is using standard particle carbon dioxide ice maker on the market, such as the granular dry ices of model KBM-300
Liquid carbon dioxide is fabricated to the graininess dry ice having a size of 2~3mm in particle device 2 by manufacturing machine, storage device 1 with
Particle device 2 is attached by process pipe 5.
In in second of forming step, graininess dry ice is subjected to briquetting into preforming device 3 by the transport of transmitting device 4
Or tabletting, wherein transporting granular dry ice can be carried out by transmission belt or chain and pan conveyor, preforming device 3 is adopted
With the cuber or pressure ice maker of standard on the market, if the not Lossen of model FCP-03K presses ice maker, preforming device 3 passes through pressure
Contracting acts on the blocky dry ice that graininess dry ice is compressed into corresponding size.
In conclusion through the invention for phone housing go flash removed dry ice production method made from it is secondary at
The blocky dry ice of type, due to being compressed using graininess dry ice, the surface of blocky dry ice is in roughness, together
When, internal structure is still to be formed by connecting by the compression of multiple graininess dry ice, and blocky dry ice is integrally in " rice cake " shape.Because of particle
It is relatively traditional direct by liquid CO 2 after the blocky dry ice of post forming there are gap between shape dry ice particles
Dry ice made of compression, the tightness between the graininess dry ice of the blocky dry ice of post forming thereon is looser, density
It is lower.When the blocky dry ice of post forming is applied in the technical process of mobile phone shell burr removal, scraper can be more easier to scrape
More graininess dry ice are taken, and the graininess dry ice size that scraper scrapes is 2~3mm, so that during deburring,
Used granular dry ices are uniform in size, reduce mobile phone shell in the defect rate and bad product rate of deburring, wherein defect rate reduces
To about 0.5%, bad frequency is reduced to about 0.1%, improves the quality of production, reduces the production cost of enterprise.
The upper only embodiments of the present invention, are not intended to restrict the invention.For those skilled in the art
For, the invention may be variously modified and varied.All any modifications made in spirit and principles of the present invention are equally replaced
It changes, improve, should all be included within scope of the presently claimed invention.
