Description
The present invention relates to a kind of device of realizing that granular dry ice divides and loads with some of being used to.
In the prior art, dry ice is made the cube of 25 centimeter square, and by being supplied to the user after the certain size cutting.Usually, the user with hammer or similarly the broken dry ice of instrument so that use.But, when the dry ice that uses through fragmentation,, thereby can not obtain the dry ice amount exactly because the size of the dry ice lumps after the fragmentation is inconsistent.Another problem is that the user should be very careful, avoids the very low dry ice lumps of direct contact temperature when using hammer fragmentation dry ice.This also makes the fragmentation of dry ice become to be difficult to grasps.Therefore, in order to calibrate filling quantity easily, people propose to adopt a kind of dry ice with short column (granular) shape (crystal grain) recently.
On the other hand, a kind of weighing powder or particulate material of being used for is so that known with the self-loading device of certain accurate quantity.A kind of structure of traditional automatic loading mechanism of this class is, bottom at a funnel, with level or bevelled mode a feedway such as auger loader etc. is installed with respect to throughput direction, and a vibrating feeder is located near the discharging outlet installation in travel line end in the face of one, so that move a spot of granular material by the vibration of described vibrating feeder, make it be conducted to one weighing and filling device that the end of described vibrating feeder is provided with, perhaps a baffle plate or a rotovalve are installed, so that finish the conveying of the material of some by the unlatching of baffle plate or rotovalve in the bottom discharge outlet of funnel.
In fact, when traditional automatic loading mechanism was used for automatic weighing and loads granular dry ice, this granular dry ice just was deformed into agglomerate in a short period of time.Caused the weight of its filling to become inhomogeneous like this.This is because dry ice has in about-79 characteristic of ℃ distillation, and the distillation gas that produces on funnel top has bigger mol wt and very low temperature, many than the surrounding air weight, therefore, when the granular dry ice of filling, this distillation gas has the trend that flows away from funnel bottom.Like this, after the distillation gas evolution, the surrounding air that is under the normal temperature just flows into described funnel, at this moment contain dry ice still in the funnel, thereby this normal temperature air just comes in contact with about-79 ℃ granular dry ice, be cooled then, airborne moisture is built up between dry ice and is solidified, so that make granular dry ice become dry ice group.Therefore, appearance can not be carried out the problem of automatic weighing and filling operation long-term and stably.
The present invention is intended to solve the aforementioned problems in the prior.The purpose of this invention is to provide a kind of device, this device can carry out automatic weighing and filling operation long-term and stably by preventing granular dry ice from clumping together in funnel.
In order to finish above-mentioned purpose, the invention provides a kind of device that is used for automatically loading granular dry ice, this device comprises an air hermetic dry ice feedway that extends airtightly from the bottom of the funnel that puts particulate dry ice, the outlet of this dry ice feedway is higher than the upper limb of funnel, a filing of containers is arranged to face the outlet setting of described dry ice feedway, the weight of this filing of containers is measured by a weighting apparatus, and the operation of described dry ice feedway is controlled according to the result of a measurement of weighting apparatus.
According to the present invention, the upper limb that is higher than described funnel owing to the outlet of the airproof feedway that extends from described funnel bottom, so the carbon dioxide that distils in described funnel remains full of the height of the outlet of feedway, like this, the inside of described funnel has been full of the carbon dioxide of distillation, thereby can prevent that outside air from entering funnel.Therefore, the carbon dioxide of distillation maintenance low temperature and almost moisture-free.By the way, when dry ice is put into described funnel, because unborn air is replaced by the distillation carbon dioxide with very big proportion in funnel before dry ice filling, so described granular dry ice can prevent the caking that caused by moisture contained in the air.
Above and other objects of the present invention, advantage and characteristics can be understood after considering following detailed description in conjunction with the accompanying drawings better, among the figure:
Fig. 1 is the scheme drawing of the structure of the expression first embodiment of the present invention;
Fig. 2 is the scheme drawing of the structure of the expression second embodiment of the present invention.
Above-mentioned accompanying drawing schematically shows the structure of embodiments of the invention.
Referring to Fig. 1, a kind of device that is used for automatically loading granular dry ice comprises a funnel 1 that is suitable for putting granular dry ice, one with the bottom opening 2 of funnel 1 bonded assembly feedway 3 airtightly, a filing of containers that below the outlet of feedway 3, is provided with 5, and described transport box 5 is located in weighting apparatus 6 thereon.
Fig. 2 represents an alternative embodiment of the invention, feedway 3 comprises the conveyor screw 17 and the bucket elevator 11 that are provided with along the funnel bottom on even keel, and this bucket elevator is arranged to link to each other with the conveying end of this conveyor screw 7 by this way: make the aperture position of the outlet 4 of this bucket elevator 11 be higher than the upper limb of funnel 1.In this case, electrical motor that drives conveyor screw 7 and the electrical motor that drives bucket elevator 11 are driven in the interlock mode, and according to the weight detecting signal of weighting apparatus 6, the running of instruction control two electrical motors that produce by described control setup 10.
Though do not illustrate among the figure, described feedway 3 also can be made of a flow conveyer, and in this case, outlet 4 also is higher than the upper limb of funnel 1.
As mentioned above, according to the present invention, because outlet 4 openings of the feedway 3 that extends from the diapire of funnel 1 become to be higher than the upper limb in order to the funnel 1 that holds granular dry ice, thereby the inside of funnel 1 has been full of described distillation gas.Therefore, can prevent that ambient air from flowing into funnel 1, makes the moisture that contains in the air can and not solidify in the intergranule condensation thus, thereby just prevented the conglomeration of granular dry ice.
By the way, according to traditional system, the particulate dry ice stream goes out the outlet at bottom of funnel to be packaged into pouch, and when the granular dry ice of packing into the funnel of 200-300 liter capacity began to operate, the dry ice that flows out funnel began conglomeration after 10-15 minute.Therefore, even the weight of weighting apparatus is set at 350 grams, the weight of the dry ice of having packed still changes to the scope of 370 grams at 340 grams.In addition, a considerable amount of dry ice still stick on the internal perisporium of funnel.In contrast, when the exit position of feedway exceeds the upper limb of funnel, nearly all dry ice all can be discharged from, and might carry out simultaneously very uniform weighing and the discharge operation, make packaging dry ice only 350 grams to 355 grams among a small circle in variation.
According to the present invention, because the outlet of the airtight dry ice feedway that extends from funnel bottom is higher than the upper limb of funnel, thereby the carbon dioxide of the distillation in funnel remains full of the height of the outlet of feedway.Therefore, be full of the almost distillation carbon dioxide of moisture free low temperature in the funnel, so just prevented that air from flowing into described funnel from the external world, thereby, granular dry ice caking prevented.Thus, carry out granular dry ice is weighed and bag packing just becomes possibility accurately.
Because for the one of ordinary skilled in the art, the present invention obviously can have many different embodiment, this specification sheets only discloses and quotes wherein some, thereby be to be understood that specific embodiments of the invention only are in order to understand the present invention's usefulness by way of example better, rather than limit it.It is also understood that under the situation of essence that does not break away from each claims of the present invention and scope, also can make multiple variation and modification these embodiment.
