Description
Technical field
The invention belongs to the agricultural products fresh-keeping apparatus, the miniature decompression fresh-keeping storage self-con-tained unit of particularly a kind of far products.
Background technology
The application of reduced pressure of nonagricultural goods processing at present self-con-tained unit all arbitrarily forms from piecing together according to provisional design, though can have the one side of flexible Application according to the needs of producing, long in time limit during erection cost, the cost height.The preservation and freshness of far products requires to keep the reduced pressure atmosphere of high humidity.Obviously nonagricultural goods is handled the preservation and freshness use that the application of reduced pressure self-con-tained unit is not suitable for far products.China Baotou far products Institute for New Technologies built up the industrialization subatmospheric pressure storage storehouse of first reserves kiloton in the world in 1994, and designed self-con-tained unit.But this device fuselage is heavy, volume is big, and is on-the-spot long in time limit, and the cost height is unsuitable for the needs of the individual production and operation form of disperseing in China rural area.
Summary of the invention
Technical matters to be solved by this invention is: provide a kind of far products miniature decompression fresh-keeping storage self-con-tained unit, be suitable for the needs of the individual production and operation form of disperseing in China rural area.Volume is little, and is in light weight, and cost is low, and convenient the installation saved installation work-hour, uses easy to operate.
Technical scheme of the present invention is:
The miniature decompression fresh-keeping storage self-con-tained unit of a kind of far products is characterized in that: be made up of with water tank, valve, controlled vacuum indicator, temperature display control switch with water tank, humidification water-ring vacuum pump, vacuum pump; The water inlet of water-ring vacuum pump is by plumbing connection vacuum pump water outlet of water tank, and the water outlet of water-ring vacuum pump is by plumbing connection vacuum pump water tank inlet; The vacuum pump bleeding point is by the plumbing connection barometric damper, barometric damper is by the plumbing connection check (non-return) valve, check (non-return) valve is by plumbing connection vacuum electric valve, the vacuum electric valve is by the plumbing connection vacuum solenoid, and vacuum solenoid is by plumbing connection humidification electromagnetic valve and aie escape valve and controlled vacuum indicator and the connecting portion that is connected pressure reduction vessel or decompression storeroom; The humidification electromagnetic valve other end is by plumbing connection humidification water tank; The signal end of controlled vacuum indicator connects the temperature display control switch by lead; Be connected the signal end of vacuum pump with the connection of the temperature sensor on water tank temperature display control switch; A control end of temperature display control switch connects vacuum solenoid by the control end of lead connection vacuum pump, another control end of temperature display control switch by lead; Another control end of temperature display control switch connects the vacuum electric valve by lead, and the control end that also has of temperature display control switch connects the control end of humidification electromagnetic valve by lead.
Controlled vacuum indicator is two same tables in parallel, reaches reliable guarantee in parallel
Effect of the present invention is:
This device volume is little in light weight, and cost is low, and convenient the installation saved installation work-hour, uses easy to operate.Be suitable for the needs of the individual production and operation form of disperseing in China rural area.Vacuum pump adopts water-ring vacuum pump; free air capacity 20-200m/h; humidification relative humidity 97%--99%; degree of vacuum 0-760mmHg scope; vacuum pump has temperature and detects fender guard automatically; vacuum solenoid, vacuum electric valve, check (non-return) valve three valves are connected in series to control and guarantee to prevent that moisture from blowing back into storage container and damaging the storage far products, are applicable to the special-purpose assorted use of miniature decompression fresh-keeping storage container of 10-50 ton or storage.
Description of drawings
Fig. 1 is the structural representation of the miniature decompression fresh-keeping storage self-con-tained unit of far products
The specific embodiment:
The miniature decompression fresh-keeping storage self-con-tained unit of a kind of far products, adopt water-ring vacuum pump, supporting with it vacuum pump water tank, be equipped with the humidification water tank, various valves, controlled vacuum indicator, and adopt the temperature display control switch totally to control, water-ring vacuum pump 1 and vacuum pump are linked to be the loop with water tank 2, to guarantee that vacuum pump normally moves, the vacuum pump bleeding point connects barometric damper 4, barometric damper connects check (non-return) valve 5, check (non-return) valve connects vacuum electric valve 6, the vacuum electric valve connects vacuum solenoid 7, vacuum solenoid, the vacuum electric valve, check (non-return) valve three valves are connected in series to control and guarantee to prevent that moisture from blowing back into storage container and damaging the storage far products.Vacuum solenoid connects humidification electromagnetic valve 8 and aie escape valve 9 and controlled vacuum indicator 10, is connected to the connecting portion 13 of pressure reduction vessel or decompression storeroom.Humidification electromagnetic valve 8 connects humidification water tank 3; The signal end of controlled vacuum indicator connects temperature display control switch 11.Vacuum pump connects the temperature display control switch with the temperature sensor on the water tank.The temperature display control switch connects the control end of control vacuum pump control end, vacuum solenoid and vacuum electric valve and humidification electromagnetic valve.
Controlled vacuum indicator is two same tables in parallel, reaches reliable guarantee in parallel.
Controlled vacuum indicator is provided with the high and low pressure scope, controls vacuum solenoid and vacuum electric valve by him simultaneously through temperature display control switch control vacuum pump.It is overheated that vacuum pump is difficult for through temperature display control switch protection control vacuum pump with the temperature sensor on the water tank.
