Description

The circulation internally scraping type slice ice machine

Technical field

The invention belongs to art of refrigeration units, particularly a kind of normal-temperature water refrigeration can being frozen scraped it circulation internally scraping type slice ice machine that is whittled into borneol again.

Background technology

Slice ice machine is divided into outer scrape formula slice ice machine and inside scraping flake ice maker, is not easy to guarantee that evaporimeter is easy to take place the coolant leakage phenomenon owing to scrape the main shaft seal performance of formula slice ice machine outward; And inside scraping flake ice maker is structurally unreasonable, brings many inconvenience to the user.

Summary of the invention

The objective of the invention is by transforming the structure of existing inside scraping flake ice maker, the existing inside scraping flake ice maker inner-tube structure of particularly a kind of improvement has more for advancing more, make inside scraping flake ice maker can make more large scale, make the excellent more circulation internally scraping type slice ice machine of refrigeration simultaneously.

Technical scheme of the present invention realizes as follows:

The present invention includes inner bag, upper end cover, bottom end cover and main shaft, the upper end cover top is equipped with decelerator, and decelerator links to each other with reducing motor, and the output shaft of decelerator links to each other with main shaft; Inner bag is connected between upper end cover and the bottom end cover by fixed block, heat-insulation layer in the outer package of inner bag, and above structure forms the housing parts of slice ice machine; The Ice scraping knife sheet is installed on two blade supports that stretched out by main shaft, and the inwall of Ice scraping knife sheet and inner bag has a gap, and this gap is in order to guarantee the thickness of borneol.When scraping ice, along with the rotation of main shaft, drive Ice scraping knife sheet carries out planetary motion along the inwall of inner bag, with the layers of ice of cutting inner bag inwall; The aproll dish is installed on the blade support on the main shaft, be used for normal-temperature water that the top is entered equably water conservancy diversion to the inner bag inwall, so that refrigeration is formed ice sheet; Main shaft is located by upper bearing (metal), upper bearing (metal) is positioned at the bearing box of upper end cover central hole, and main shaft is supported by lower bearing, and lower bearing is positioned at the bearing box that is located at the tripod centre bore, tripod is the core of bottom end cover, tripod bear whole main shaft with and go up the weight of part; The bottom end cover periphery is provided with guiding gutter, the bottom of main shaft is provided with drip tray, the water that freezes that flows down along the inner bag inwall is accepted by drip tray and is flowed in the guiding gutter again, outer wall at guiding gutter has opening to be connected with water tank, the outside of water tank is provided with pump motor, and the surplus water that flows into water tank leads to a inlet opening on the upper end cover by the suction pump in the water tank by a circulating water pipe that connects and flows to the aproll dish and circulate.

Inner bag is a toroidal shell, in the thickness range of housing, along toroidal shell axially, offer spirality pipeline (similar helical spring structure) from top to bottom, the front end of spirality pipeline communicates with the external world, constitutes the refrigerant import, and the end of spirality pipeline also communicates with the external world, constitute refrigerant exit, its whole formation coolant path.

Described spirality pipeline can be one, in this case, has only 1 refrigerant import and 1 refrigerant exit, forms the coolant path structure of one-in-and-one-out on the whole; If inner bag is bigger, spirality pipeline can be many, and wherein each bar spirality pipeline all has a refrigerant import and a refrigerant exit, has formed on the whole and has advanced the coolant path structure that has more more; The described coolant path structure of advancing to have more can be a coolant path structure of two advancing two to go out, three advance three to go out, four advance four to go out, five advance five to go out, six advance six to go out, seven advance seven to go out (by that analogy more more number) more.

Ice-making process is roughly as follows: the water of ice making enters water tank, uninterruptedly flow into the aproll dishes by circulating pump in a large number through circulating water pipe, drive the main shaft of uniform rotation again by decelerator, the water of aproll dish is flowed down along the inwall of inner bag uniformly, most water is cooled in the inner bag inner wall surface and freezes, the Ice scraping knife sheet that the ice of moulding is driven by main shaft is cut into the approaching thin splinter of size, and landing goes out bottom end cover.And the remaining cooling water that does not freeze fully is by the guiding of the drip tray of bottom, flows into water tank through the guiding gutter of bottom end cover periphery, carries out circulation next time again.

Described inner bag material is an almag, also can be materials such as carbon steel, stainless steel, low-temperature steel, and the surfaces externally and internally of inner bag is handled through hard anodizing, makes it that oxide layer be arranged.

Advantage and effect that the relative prior art of the present invention is had are as follows:

1. refrigeration excellence: advance to have more and the revolution refrigerant inner bag access structure that vertically spirals more, guaranteed the feed flow balance, make from top to bottom evenly refrigeration, icing face evenly distributes, and ice sheet is peeled off effective;

2. heat transfer effect is good: the inner bag material is an almag, with material contrast such as existing stainless steel commonly used, steel, iron, almag heat transference efficiency height, water is through inner bag bucket wall, can in the shorter time, build-up ice under the cold-producing medium effect, that is to say and under identical refrigerating capacity and working condition, can improve ice-making capacity greatly;

3. surface treatment: the surfaces externally and internally of inner bag is handled through hard anodizing, this surface treatment method not only makes it to have Corrosion Protection, and the more important thing is and make that peeling off of borneol is more complete, slyness is carried out, prevent the remaining better effects if of residual ice, make the running of slice ice machine continue smooth and easy more.
