According to tableware cleaning device described in the utility model, be preferably, the dry ice material tube inner wall in the described feeding distribution mechanism is provided with thermal insulation layer.
The bottom of the dry ice barrel in the feeding distribution mechanism is equipped with tripper, connects with the low-pressure gas pipeline by three-way connection again.Owing to have pressure in the pipeline, can from barrel, enter low pressure pipeline smoothly for making dry ice, in the barrel certain pressure should be arranged, we select for use threeway that one road low-pressure gas is inserted in the barrel.Therefore, barrel should be a pressure vessel.Can absorb a large amount of heat from surrounding environment during dry ice sublimation, therefore, material tube inner wall should have thermal insulation layer.
According to tableware cleaning device described in the utility model, be preferably, described spraying system comprises that spray gun, Venturi nozzle, mixing chamber and dry ice particles transmission are used and pressure-air transmission dual circuit, the described feeding distribution mechanism port of export and described venturi nozzle end are communicated in the described mixing chamber, and above-mentioned dry ice particles transmission is used and the pressure-air transmission is connected with the port of export and the described venturi nozzle of described feeding distribution mechanism respectively with dual circuit.
According to tableware cleaning device described in the utility model, be preferably, to use in the dual circuit in dry ice particles transmission usefulness of the present utility model and pressure-air transmission, dry ice is carried by the low-pressure gas pipeline.
The pipe-line system of Dry ice cleaning has single flexible pipe and two kinds of two hose.When single flexible pipe was worked, pressure-air and dried dry ice particles were mixed in one, produce continuous specified ice stream (high efficient, high pressure), its production cost height, and maintenance load is big, is suitable for the high pressure transfer system of working energetically the ice stream amount; In two flexible pipes (Fig. 2) when work,, dry ice particles and pressure-air in two flexible pipes, are applicable to the low pressure transfer system of low dry ice flow respectively before the ejection gun barrel, have the ice consumption less, advantage that use cost is low.
In dual circuit of the present utility model system, because the length of dry ice is wide greater than nozzle, so the mode that the dry ice spray gun will adopt dry ice to mix with high-speed gas quickens, and abrasive material mixes the mode of acceleration again with gases at high pressure unlike sand-blasting machine.
According to tableware cleaning device described in the utility model, be preferably, the tripper in the described feeding distribution mechanism is a leaf structure.
The bottom of the dry ice barrel in the feeding distribution mechanism is equipped with tripper, connects with the low-pressure gas pipeline by three-way connection again.Owing to have pressure in the pipeline, can from barrel, enter low pressure pipeline smoothly for making dry ice, in the barrel certain pressure should be arranged, we select for use threeway that one road low-pressure gas is inserted in the barrel.Therefore, barrel should be a pressure vessel.Can absorb a large amount of heat from surrounding environment during dry ice sublimation, therefore, material tube inner wall should have thermal insulation layer.
According to tableware cleaning device described in the utility model, be preferably, the diameter of described Venturi nozzle is 3-7mm.
The nozzle that the industry shot-peening cleans usefulness is a Venturi nozzle, calculate and practice all shown Venturi nozzle than normal straight tube nozzle under identical operating mode, jet velocity is higher, cleaning performance is better, shot-peening is more even.Usually the shot-peening nozzle diameter is 9.5mm or 11.1mm, and nozzle is big more, and it is big more that the capacity of air compressor machine also requires, and the consumption of abrasive material (dry ice) is also big more.Therefore consider that air compressor machine capacity and operating pressure and dry ice consume quantitative limitation, we choose the nozzle of 3-7mm.
Different with industrial shot-peening cleaning is, dry ice particles is diameter 3mm, the cylinder of length 2.5～10mm, the industry shot-peening cleans used abrasive size and generally is lower than 0.2mm, therefore dry ice particles can't be by the nozzle of 3-7mm, this just Dry ice cleaning never have one of reason of miniaturization---the contradiction between the dry ice particle diameter limits nozzle with the air compressor machine capacity the requirement of jet size.
This method is to improve air pressure by air compressor, then increase substantially jet velocity by venturi nozzle, form negative pressure at the mixing nozzle place, with the dry ice particles sucking-off feeding distribution mechanism of 2-4mm by shower nozzle with after high-speed air fully mixes, be ejected into material surface, make dry ice particle impact distillation rapidly behind the thing to be cleaned surface, realize cleaning.
Dry ice cleaning can not damaged material surface.Dry ice cleaning system can be according to user's needs, dry ice preparation system and dry ice blasting system support fitted together as a cover system use. also the dry ice preparation system can be separated with the dry ice blasting system, just as the production equipment of supplying raw materials, the dry ice blasting system is used to clean engineering separately to the dry ice preparation system.The dry ice particles of 2-4mm can be bought from market and obtain, or uses the dry ice particles maker to be power source by compressed air, will be made into liquid CO 2 the particle of 2-4mm.
Dry ice clean technologies principle is to make different material produce disengaging under different contraction speeds with temperature difference physical reactions, the surface adhesion thing can be cooled and the catalysis explosion simultaneously, produces " little gas explosion " stripping usefulness with 800 times of volume instantaneous expansion after compressed air stream and the dry ice gasification again.This temperature difference physical reactions is to disperse to absorb treatment surface heat energy with the air pressure acceleration dry ice to make its rapid contraction and disengaging is torn in the unstructuredness connection, and the bigger generation temperature difference of air pressure reflects that the fast effect that heals heals obviously.Or still locate high temperature following time when working surface, and use dry ice blasting, it is even more ideal then can to produce bigger temperature difference effect.
According to above-mentioned, the utility model be with the dry ice particles of Manufactured 3mm through with the mixing of high-speed gas after, the surface that bump needs to clean forms little gas explosion, spot " is blown up " thus reach the purpose that washes the dishes.
System utilizes the compressed air of the compressed air system generation of self preparing. the dry ice particles of in cleaning device, packing into and having made; under compressed-air actuated driving; high density dry ice particles or fine powder are cleaned body surface along with compressed air impacts, thereby play cleaning action.
According to schematic diagram of the present utility model, the gases at high pressure that come out by compressor are divided into two-way, one the tunnel drives dry ice particles after the decompressor decompression arrives nozzle, another road gas reaches by Venturi nozzle earlier and sprays required speed arrival nozzle place, simultaneously high-speed gas the nozzle place form negative pressure to pipeline in dry ice the effect of sending of inhaling is arranged, low pressure dry ice air-flow and high-speed air flow fully mix the back ejection at the nozzle place like this, clean.
The bottom of the dry ice barrel in the feeding distribution mechanism is equipped with tripper, connects with the low-pressure gas pipeline by three-way connection again.Owing to have pressure in the pipeline, can from barrel, enter low pressure pipeline smoothly for making dry ice, in the barrel certain pressure should be arranged, we select for use threeway that one road low-pressure gas is inserted in the barrel.Therefore, barrel should be a pressure vessel.Can absorb a large amount of heat from surrounding environment during dry ice sublimation, therefore, material tube inner wall should be established thermal insulation layer.
In dual circuit of the present utility model system, because the length of dry ice is wide greater than nozzle, so the mode that the dry ice spray gun will adopt dry ice to mix with high-speed gas quickens, and abrasive material mixes the mode of acceleration again with gases at high pressure unlike sand-blasting machine.
The utility model is by the pipe-line system of design different pressures, air hose and two pipelines of dry ice pipe are separated, dry ice will be carried by special low-pressure gas pipeline, separate introducing with gases at high pressure, can increase substantially speed by venturi nozzle simultaneously and increase kinetic energy.In the spraying system part, the mode that the dry ice spray gun will adopt dry ice to mix with high-speed gas is quickened, and makes jet velocity faster, and cleaning performance is better.Simultaneously, also with industrial Dry ice cleaning equipment miniaturization, make it can be used for family food hygiene field.
The utility model has the advantages that:
(1) conserve water resource.Utilize solid dry ice particles and high-speed gas to clean, the complete unfavorable water of cleaning process has fundamentally reduced the phenomenon that common cleaning technique causes a large amount of wastes of water resource, effectively protects, saved water resource.
(2) no cleaning agent is residual.Owing to the bowl that spot is arranged is directly cleaned, so can raise the efficiency; Owing to do not need residual cleaning agent is cleared up, reduced running cost; No cleaning agent residual, thereby equipment do not caused a hidden trouble.
(3) human body and environment are not produced harm and pollution.Utilized the waste gas carbon dioxide, reduced the discharging of greenhouse gases, to zero environmental, especially dry ice has avirulence, and this is that other cleaning agents are incomparable.
(4) do not wear and tear and be cleaned thing surface surface.The unique distinction of Dry ice cleaning is that dry ice particles is in impact moment gasification.The momentum of dry ice particles is impacting pop-off.Heat exchange takes place rapidly between dry ice particles and clean surface.Cause dry ice, distillation becomes gas rapidly.Dry ice particles expands nearly 800 times in some thousandths of inner volume second.So just cause miniature blast at shock point.Because dry ice particles distillation becomes gas, and dry ice particles only was for 1 second by distillation time of solid-state change gaseous state, so dry ice particles substantially can not cause any infringement to the surface of cleaning thing under the short time effect.
(5) has sterilizing function.Because the dry ice particles temperature only has-78.5 ℃, under low like this environment temperature, most of bacterium and virus all can't be survived, the complete like this purpose that can reach sterilization, and because clean and sterilization be carry out simultaneously so also improved overall efficiency.
