The utility model provides a reduced -pressure storage cabin body adopts cylindrical barrel and oval tip to gain in strength through enclosing the seat, it is withstand voltage effectual, do not need additionally to dispose the freezer or at the internal or external configuration heat exchanger in cabin in cabin, save space, heat exchange tube and barrel direct contact, the heat transfer is effectual, is favorable to refrigerating unit's energy -conservation, the heat exchange tube guarantees in surperficial the arranging evenly of barrel that the internal temperature in cabin is even.
Description
Technical field
This utility model relates to a kind of agricultural products storage and preservation device, particularly a kind of subatmospheric pressure storage nacelle。
Background technology
Agricultural product decompression fresh-keeping storage is to be placed in subatmospheric pressure storage nacelle or tank body and maintain low temperature, low pressure and high humidity state by the agricultural product through pre-cooling, to reduce the respiratory intensity of agricultural product, and the biosynthesis of ethene suppressing, thus delay the fresh-keeping mode of one of agricultural product ripening and senscence。
For maintaining the low temperature state of agricultural product in decompression nacelle or tank body, common method has following three kinds:
Method one is decompression nacelle to be placed in a low-temperature cold-storage, as described in patent CN03214631 " small-sized subatmospheric pressure storage preserving fruit and vegetable utilizing device " and patent CN200720061505 " a kind of fruit and vegerable reduction store fresh-keeping apparatus "。This method not only needs additional configuration freezer, and the heat transmission between nacelle surface and freezer vaporizer requires over the air in storehouse as intermediate medium, heat exchange efficiency is low, and freezer is relatively big with the contact area of external environment condition simultaneously, also produces extra energy consumption。
Method two is that heat exchanger is placed in portion in decompression chamber body, as described in patent CN200620109794 " pressure-reducing fresh-keeping storage apparatus "。This method makes effective storage in portion in decompression chamber body be greatly decreased because heat exchanger takes up room, and simultaneously because the inside of nacelle or tank body is in vacuum state, the heat exchange effect of heat exchanger is poor, and in cabin, temperature is not easy uniformly everywhere。
Method three is to arrange an air treatment system outside subatmospheric pressure storage nacelle, as described in patent CN201420500656 " decompressing storage device ", is caused by air in cabin after air treatment system out of my cabin carries out cooling down and humidify in return capsule。Air handled by this method hollow gas processing system is high humidity low density gas, evaporator heat exchange weak effect, and dehumidifying load is bigger simultaneously。
Summary of the invention
The purpose of this utility model is the technological deficiency overcoming existing decompressing storage device to exist, it is provided that a kind of compressive resistance is good, and can directly connect cold-producing medium carries out freezing to maintain the subatmospheric pressure storage nacelle of low temperature in cabin simultaneously。
Subatmospheric pressure storage nacelle of the present utility model, including the cylinder with hatch door, is evenly distributed with the heat exchanger tube connected with refrigerating plant on the outer surface of described cylinder, is provided with the port for connecting air inlet pipe, exhaustor, sensor on described cylinder；It is provided with in the outside of cylinder and encloses seat, bearing for support is arranged below what enclose seat；Described cylinder, heat exchanger tube, enclose seat, all there is heat-insulation layer in the outside of hatch door。
Subatmospheric pressure storage nacelle of the present utility model, cylindrically, one end of cylinder is spheric termination to wherein said cylinder, and described hatch door is connected with the other end of cylinder by flange。
Subatmospheric pressure storage nacelle provided by the utility model, adopts cylindrical tube and spheric end, and increases intensity by enclosing seat, pressure effective；Do not need additional configuration freezer or in nacelle or outside nacelle, configure heat exchanger, saving space；Heat exchanger tube directly contacts with cylinder, good effect of heat exchange, is conducive to the energy-conservation of refrigeration unit；Heat exchanger tube is uniform in the layout of drum surface, it is ensured that the homogeneous temperature in nacelle。
Accompanying drawing explanation
Fig. 1 is the structural representation of this utility model detailed description of the invention；
Fig. 2 is the A-A cross-sectional schematic shown in Fig. 1。
Detailed description of the invention
As shown in Figure 1, 2: 1 is cylinder, is provided with hatch door 28 on cylinder 1, cylindrically, one end of cylinder 1 is spheric termination 29 to cylinder 1。Hatch door 28 is connected with the other end of cylinder 1 by a pair flange 27, and the composition surface place of flange 27 is provided with groove, is provided with seal washer in groove。On the outer surface of cylinder 1, on the outer surface including termination 29, it is fixedly connected with the heat exchanger tube 24 connected with refrigerating plant equally distributed, ordered arrangement by welding manner。Cylinder 1 is provided with the port for connecting air inlet pipe, exhaustor, sensor and observation window。It is fixed with at least two in the outside of cylinder 1 and encloses seat 30, enclose the bearing 31 being arranged below for supporting of seat 30。The inner side enclosing seat 30 is provided with U-shaped opening with heat exchanger tube 24 intersection, makes heat exchanger tube 24 be located just in this opening。Heat exchanger tube 24 for organize parallel-connection structure, and can have same medium inlet 25 and media outlet 26 more。Heat exchanger tube 24 can be parallel to the axis direction reciprocating and turning-back arrangement of cylinder 1, or is wound on the outer surface of cylinder 1 in order, and termination 29 and the heat exchanger tube outside hatch door 28 are evenly distributed in order along its curved surfaces。Cylinder 1, hatch door 28, enclose seat 30, bearing 31 is stainless steel material or carbon steel material make。Cylinder 1, heat exchanger tube 24, enclose seat 30, all there is heat-insulation layer in the outside of hatch door 28, heat-insulation layer adopts rubber and plastic warming plate or formed by polyurethane foam。
During installation, this nacelle is supported by bearing 31 and is fixed on base surface, and the air inlet port on cylinder 1 is connected with feeder by pipeline, for supplying live gas to nacelle inner chamber。Exhaust port is connected with asepwirator pump device by pipeline, for the gas of sucking-off nacelle 1 inner chamber。Sensor port is provided with and controls the sensor that device connects, for detecting the pressure of nacelle 1 inner chamber, temperature etc.。Medium inlet 25 and the media outlet 26 of heat exchanger tube 24 connect with refrigerating plant。This subatmospheric pressure storage cabin can ensure ventilation in time, humidification, decompression, cooling in cabin when running, agricultural product have good fresh-keeping effect, and nacelle intensity is good simultaneously, occupies little space。
