Description
Technical field
The utility model relates to quick freezing unit technical field more particularly to a kind of automatically stack formula spiral liquid nitrogen flash freezer machines.
Background technique
In existing quick-frozen industry field, screw fast refreezer is all using freon refrigeration unit or liquefied ammonia refrigeration machine
Group, although the efficiency of liquefied ammonia refrigeration unit is relatively high, because industrial accident quite has generation caused by A leak of liquefied ammonia, and by state
The limitation of relevant departments, family is even forbidden to use；Therefore, the screw fast refreezer of freon refrigeration unit is widely used in quick-frozen row
In industry.There are two types of the network chain methods of operation of traditional screw fast refreezer, one is supporting network chain to run by support guide, separately
One is run using stacked network chain.
Network chain is supported to run screw fast refreezer using support guide at present, the problem is that equipment is huge, support branch
Frame and guide rail quantity are more, it is difficult to which the corner or spot as yet untouched by a clean-up campaign of processing is more, and frictional resistance is big, and network chain is easy overturning and collapses when operation, causes to stop
The power of machine or network chain damage, driving network chain operation is by two motors, and one is Rolling motor, and one is network chain motor,
The starting revolving speed of two motors is inconsistent, if two motor speeds are asynchronous, it will cause network chain overturnings to collapse, and gently then stops
Machine is heavy then damage network chain.
Existing stacked screw fast refreezer, in the lower section of spiral network chain, network chain is loaded into the chain of two special constructions
On, the drive chain of this two special constructions is slided item, chain etc. and is formed by metal abnormity spherical guide, ball, plastics.This two
Root chain is respectively positioned on overhead two helical orbits, and respectively under the drive of two driving motors, two sections of chains
The screw of annular is done respectively, and conveying network chain is held on drive chain by plate washer, boom, network chain composition, conveying network chain plate washer
On, it is run by the driving of inside and outside two chains, network chain stacking in layer, continuous service from bottom to top, therefore complete transmission net
Chain accumulates spiral motion certainly；The problem is that:
1) chain of special construction, be made of ball, need oily, chain is easily damaged if oil lacks, In
Under hot environment, oil is easy evaporation and chain is caused to damage, under ultra-low temperature surroundings (- 100 DEG C~-0 DEG C).Oil is easy to freeze
And chain is caused to damage, network chain and motor are restricted using temperature condition, because driving motor arranges enclosure interior.
2) driving of two chains relies on two motors, and two motors are asynchronous or a motor damage, gently it will cause
It shuts down or network chain overturning is collapsed, it will cause network chains or chain to damage for weight.
3) chain link of stacked network chain is formed using steel plate bending or punch process, and finished-product volume is big, and weight weight rubs
It is big to wipe coefficient, and the height for making the support plate of supporting role is shorter, is not able to satisfy the requirement that product uses comprehensively, while as branch
Fagging, although being disposed with hole above to increase the mobility of air-flow, aperture is generally all smaller, in use, serious to limit
The flowing for having made low-temperature airflow reduces the heat exchanger effectiveness of article, energy consumption is caused to increase, waste of energy.
4) drive chain is in spiral network chain lower part, if drive chain is damaged, maintenance load is big, also highly difficult.
Conventional helical instant freezer is limited by freon refrigeration unit cryogenic temperature (< -35 DEG C), cannot completely keep being frozen
The original flavor of food and quality.
