Abstract

This invention discloses a kind of ice-making equipment for drossy ice. Its carapace structure, combined with the inside and outside canister, the ends are closed entirely, forming lumen and inside sleeve. Installing ice scaler in the middle of the lumen, which is composed of axes with springs and reamer. The left side of the ice scaler is connected to strap wheel. Four linkers are set on the ice-making equipment. The output and input segments of the iced water are connected to lumen, and those of the natural water are connected to inside sleeve. This ice-making equipment is designed uniquely. Reamer is made floating, connected to the icing surface closely for the function of ice scaler, and makes heat-exchanging and ice-producing more efficacious.

Description

Ice maker

Technical field

The present invention relates to a kind of ice maker, particularly relate to a kind of ice maker that is used for producing the trash ice crystalline substance.

Background technology

Usually, central air conditioner system is to produce chilled water about 7 ℃ by refrigeration machine, being transported to air conditioner end equipment freezes, that is to say, the dielectric that pipeline flows between refrigeration host computer and air conditioner end equipment is a chilled water, such air-conditioning absorbs heat by chilled water and cools off air, does not have the process of latent heat of phase change.Have a kind of latent heat type air-conditioning to research and develop in recent years, the latent heat type air-conditioning is that refrigeration unit is made ice crystal, and ice crystal is transported to the air conditioning terminal refrigeration.Utilize this technology can dwindle conveyance conduit greatly, reduce the insulation material consumption significantly, save pump power and save building space, may become the once new revolution of central air-conditioning.Owing to do not have effective equipment aspect the short grained ice crystal producing continuously in a large number, restricted the application of such air-conditioning greatly.Other has a class air-conditioning, is called " ice-storage air-conditioning ", and it is that (at night) starts the refrigeration machine refrigeration during the non-peak value electricity price, with Water freezes into ice, the form of cold with ice is stored; The expensive period ice-melt of (daytime) electricity price during the peak value electricity price, the cooling chilled water, chilled water is transported to air conditioner end equipment and removes to cool off air.If trash ice form cold-storage provides speed of cooling very fast during ice-melt, be 3-5 times of berg form cold-storage.Domestic disclosed Patent data, as " dynamic trash ice ice machine of single-bolt type and ice making method thereof (application number: 01107599.6) ", " water distribution wortex device of tubulose ice machine and cut ice production apparatus (93222650.7), " continous way internal and external screw ice maker (application number: 91226179.X) " etc. application number:; they provide the different methods of producing borneol or trash ice respectively; but there is common shortcoming in these methods: the Ice scraping knife fixed installation; have the gap with icing surface; form one deck thin ice; increase thermal resistance, reduced heat exchange efficiency at this gap location.The fixed installation mode of above-mentioned skates is the skates spirality to be welded on scrape on the ice device axle, or directly processes skates scraping on the ice device axle, haves much room for improvement.

Summary of the invention

The object of the present invention is to provide a kind of ice maker, its structural design uniqueness can be produced the trash ice crystalline substance, and skates are to float to install, and skates closely contact with the surface that freezes all the time under the thrust of spring, thereby ice making efficient is provided.

Ice maker of the present invention is a shell---the shell-type structure, and the metal inner core is enclosed within the urceolus, and is sealed at both ends, forms inner chamber and chuck; Scrape the ice device in the installation of inner chamber middle part, scrape the ice device and form, connect belt pulley at the left end of scraping the ice device by axle and the spring and the Ice scraping knife that are installed on the axle; At ice maker four connectors are set respectively, chilled water inlet and chilled water outlet and intracavity inter-connection, non freezing solution inlet and non freezing solution outlet are connected with chuck.

Described Ice scraping knife is installed at least one Ice scraping knife on each section at least one section Ice scraping knife along the axial installation of scraping ice device axle.For the long ice device of scraping, adopt the multisection type skates, reduce single stressed skates; Each section employing is many can to make skates the radial force of scraping ice device axle more even.

The mounting means of described Ice scraping knife is: axially process the skates mounting groove along what scrape ice device axle, at least one spring and Ice scraping knife are installed in groove.Ice scraping knife stretches out outward and is close to the inner core inwall under the thrust of spring, by the belt band, scraping the ice device rotates, Ice scraping knife can be with also scraping on the inner core inwall fully, chilled water directly contacts with inner core inwall metal, do not have ice sheet to intercept between them, improve heat exchange efficiency and ice making speed.The unsteady great advantage that skates are installed that Here it is.

The end rounding of described each groove.To be compressed in the return-enclosure when Ice scraping knife is subjected to big pressure, the end rounding of groove can prevent that Ice scraping knife from blocking.

The two ends, the left and right sides of described urceolus are respectively by first member plate, right end plate sealing, rubber seal on pad between end plate and the cylindrical shell.

Described right end plate central authorities are fixed with bearing block, and bearing directly is placed on the bearing block, does not need other support, conveniently scrape the installation and removal of ice device.

Than existing ice maker, ice maker of the present invention has the following advantages:

1. can produce the ice crystal of 100 μ m ~ 1mm continuously, it is little to make the ice pellets that comes than conventional ice maker, is fit to pipeline transportation.

2. skates are installed for floating, and closely contact with the inner core wall, reduce thermal resistance, guarantee high heat exchange efficiency.

3. skates are installed for floating, and the skates wearing and tearing are little, when the skates resistance is big, and its indentation automatically; After the skates wearing and tearing, it can stretch out automatically, closely contacts with the inner core wall.

4. skates are installed for floating, and can regulate installation dimension automatically, require low to scraping ice device installation accuracy.Working properly under the bigger environment of vibration, ice maker is not easy to damage.
