Device for preparing ice slurry by use of spiral drawknife device

Abstract

The invention discloses a spiral drawknife device for preparing an ice slurry. The device is capable of preventing from producing ice block due to excessively thick ice layer, reducing replacement of drawknives and reducing the production cost, and is convenient in use. The device comprises an ice slurry generator and an ice scraping mechanism, wherein the ice scraping mechanism comprises a motor, a spiral shaft and a spiral scraper arranged on the spiral shaft, the spiral scraper is stretched along an axial direction, and the spiral direction of the spiral shaft and the spiral scraper is a direction of ice slurry solution flowing toward an ice outlet; the spiral shaft is driven by the motor, and the spiral shaft is arranged on an axial line of the ice slurry generator. The structural features of the spiral shaft and the spiral scraper are used by the device for preparing the ice slurry by use of the spiral drawknife, the ice slurry solution flows towards the ice outlet under an axial force effect, the ice layer is timely destroyed under a peripheral force effect, the ice block due to the excessively thick ice layer is prevented from being produced, and the working efficiency is high. Meanwhile, the mechanical wear of the spiral scraper is relatively less without being frequently replaced, the service life of the spiral scraper is prolonged, the replacement cost of the spiral scraper is reduced, and the production cost is lowered.

Description

technical field [0001] The invention relates to the technical field of ice slurry preparation, and more specifically relates to a spiral scraper ice slurry preparation device. Background technique [0002] Since the 20th century, the industry has developed rapidly, but at the same time, the problem has been excessive energy consumption, non-renewable resources are facing exhaustion, the natural environment has also been damaged to varying degrees, and the problem of energy shortage needs to be solved urgently. In order to alleviate this situation, cold storage technology was proposed and developed rapidly, and ice storage first entered people's field of vision. Ice-slurry cold storage technology can solve the current problems of urban electricity shortage and power loss, and play the role of "shaving peaks and filling valleys". The cold energy is stored in the ice by using the sufficient and low-cost electricity at night, and the ice is melted during the peak power consumpt...

AI Technical Summary

Problems solved by technology

However, since ice crystals are generated on the wall of the ice slurry generator, it is very easy to form a thick ice layer, which not only hinders the heat exchange between the aqueous solution and the refrigerant, but also seriously damages the ice making container.

At the same time, since the scrapers of the current equipment for making ice slurry are all rotary, the rotary scraper scrapes the wall of the ice slurry generator as a whole, and the ice layer generated on the wall is scraped off, causing wear and tear on the rotary scraper, which needs to be dismantled regularly. The machine is replaced, which increases the production cost and brings great inconvenience to the preparation of ice slurry
