Description

10 Tons railway cold container with fixed cold plate

The utility model is a kind of equipment that is applicable to the Railway Refrigerated Transport container shipping, belongs to temperature automatically controlled cold drawing cold-storage technical field.

China reaches annual more than 1,200 ten thousand tons through the perishable freight freight volume of railway transportation at present, and development prospect needs will reach about 100,000,000 tons by this kind goods of railway transportation.But with regard to present capacity, also have only 7% freight volume with the refrigerated railway car transportation, all the other a large amount of perishable freight are with box car or open-top car transportation, rotten decrease serious, so cold storage carrying equipment needs to be resolved hurrily.And the van cooler in the middle of the utilization now also can only use on railway line, will just can transport to owner of cargo locus through upside-down mounting after goods arrives at a station, and certainly will increase the handling labor amount of goods, increases traffic cost, and the owner of cargo also feels inconvenient.Simultaneously and since present stage the dress that is suitable for of China railways hang equipment and lack, add refrigeration power supply supply bottleneck in the railway transportation way, so it is also very difficult to adopt large-scale international standard mechanical refrigerator container to enter the China Railway industry.

The purpose of this utility model just provide a kind of deposit that can satisfy the railway transportation requirement more than seven days low-temperature receiver and also can realize ten tons of fixedly refrigerator containers of railway that deliver goods is got home.

Contour dimension of the present utility model and existing ten tons of general cargo containers of China railways are identical, are convenient to turnover and use, and the outside plate of this container shell (12) is A ₃Steel, inner panel are corrosion-resistant steel, and the centre accompanies the thick hard polyurethane fat plate (8) of 100mm and makes.At the case inner top two blocks of fixing cold drawings (1) of symmetry are set, the two ends that every block of cold drawing covers are provided with a spiracle, have poured into the secondary refrigerant of enough keeping shipment perishable freight cold more than seven days in the case in the cold drawing.Cold drawing be erected at by in the case along on the high support of forming for the H-girder of 330mm (2) of eight pillars (11) of both sides abutment wall and the middle wing longitudinally, cold drawing is steadily held in the palm at the case inner top.Fill cold-peace is carried out precooling to goods in the case purpose fast in order to reach cold drawing, in case, be provided with below the preceding inlet side than the twice freezing unit of common refrigerating capacity (6), congealing machine joins by circumscripted power line and the external power supply of a long 30m, the refrigeration of machining, freezing unit are subjected to the temperature inside the box control to reach the requirement of refrigerating auto-control.Two condensers (4) and a pair of condenser fan (5) are housed in the top of freezing unit (6), disperse condenser in process of refrigerastion (4) liberated heat with condenser fan (5).Condenser (4) is to be connected with cold drawing (1) with evaporation tubes (3), and the part evaporation tubes (3) that stretches into cold drawing (1) constitutes the interior evaporator of cold drawing, causes the large tracts of land cold scattering, makes the secondary refrigerant in the cold drawing fill cold rapidly.Reach the requirement of refrigerating auto-control with temperature control.Be provided with the tubular electric heating element of two evaporating fans (13) and two each 500W in top, the preceding inlet side of casing (12), purpose is to cross the uniform temperature that keeps the case planted agent to have when hanging down for all even boundary outside of precooling in the case, temperature temperature.For making wind circulation in the case, be provided with the ventilation rail (10) of aluminum alloy at the case inner bottom part, form air flue jointly with the cold drawing pillar gap of case inner end wall: for making box sealing, prevent gas leakage, this kind deep freezer is only installed a fan chamber door (10), the sealing means that the sealing of door has adopted " O " type rubber seal and multi shields insulation shirt rim to combine.A floor drain (7) is set on the floor of preceding inlet side in case, floor drain is to make with the nylon thermal insulation material, a lifting rod is installed at its pipeline tapping place, the goose neck pipe that the lower end of bar is adorned outside a soft rubber ball and the case constitutes one group of water-gland, reach the requirement that can drain the water away and can prevent to leak gas, be beneficial to maintenance the temperature inside the box.

Provide embodiment below in conjunction with accompanying drawing.

Fig. 1 is the cutaway view of refrigerated container.Among the figure: 1-cold drawing, 2-H-girder, 3-evaporation tubes, 4-condenser, 5-condenser fan, the freezing unit of 6-, 7-floor drain, 8-hard polyurethane fat plate, 9-chamber door, 10-ventilation rail, 11-pillar, 12-casing, 13-evaporating fan.

At first energized is started freezing unit (6); compressed refrigerant enters cold drawing (1) through condenser (4) and evaporation tubes (3); secondary refrigerant in the cold drawing is freezed, treat that secondary refrigerant reaches when 7 to 10 days cold of goods cold scattering in the case required just to shut down.Starting condenser fan (5) and evaporating fan (13) simultaneously distributes condenser (4) liberated heat and can make and have a constant temperature in precooling in the case, all even maintenance case of temperature and become.Because casing (12) is a leak free in refrigeration and cold scattering process, air circulates by ventilation rail (10) and air flue in the case.The condensate water that produces in the case flows to the floor along wall, then is pooled to floor drain (7) and locates.Discharge from the ground leak, to reach long-time insulation refrigeration, the fresh-keeping purpose of goods.For obtaining good sealing effectiveness, this floor drain (7) is the pipeline made from thermal insulation material nylon, the pipeline tapping place is provided with a lifting rod, and a soft rubber ball is equipped with in the lower end of lifting rod, and the outer goose neck shape drain hose of floor drain pipeline and case is formed a good water-gland.
