Description

Machinery cold drawing formula refrigerated container

The utility model relates to a kind of cold storage carrying equipment, particularly a kind of refrigerated container.

The ice-cold van cooler of known railway adopts water salt refrigeration, in transit, the salt solution that it overflowed, facilities such as heavy corrosion vehicle, rail and bridge, and have shortcomings such as contaminated environment, fresh-keeping of poor quality and freight rate height; A kind of mechanically refrigerated truck is arranged, though performance is better than above-mentioned ice-cold van cooler, the price height, freight rate is higher.More than two kinds of refrigerated railway cars, all can not realize " door t door " transportation.The mechanical refrigerator container that also has a kind of international standard abroad, though its performance is good, freight department's difficult management, its fatal weakness are to need continuous electric power supply in the way, and the railway transport vehicle of China there is no the condition of electric power supply, so can not carry.Highway, water route also must be equipped with enough power equipment supply and could carry.In addition, produce this refrigerated container, its equipment investment and technical requirements are all very high, and cost is also high.Owing to there are these defectives, make the development and the use of existing refrigerated container, be subjected to great restriction.

The purpose of this utility model is to provide a kind of power supply that need not in transit, and transportation administration is convenient, and cost is low, and railway, highway, water route are general, and can realize the refrigerated container that " door t door " transports.

The utility model is to utilize the freight container of international standard as shell (1); top in case, bottom, each side and door; respectively install mutual close-connected inner panel or the floor ventilation rail made with hard material additional and form inner casing (2); the thermal insulation layer (3) that between shell (1) and inner casing (2), has a usefulness thermal insulation material to make; in case one jiao; the refrigerating unit (4) of tool monitoring and fender guard is installed, the top in case, lifting is in order to the cold drawing device (5) of cold-storage.This cold drawing device (5), the flat box-like hollow cold drawing shell (9) that is welded by hard plate material and the evaporating coil (11) of interior dress refrigerant and nontoxic, do not have corrosion and the little colloid shape agent for storage of coldness (10) of coefficient of expansion is formed, bottom and both sides at cold drawing shell (9), be welded with radiating gill (12), at an upper portion thereof, an agent for storage of coldness filler opening (13) is arranged, filling screw plug (14) is arranged in filler opening (13), in addition, also has a gravity type boat davit safety valve (15).When using the utility model, it is cold only to need to utilize source of AC starting refrigerating unit (4) to fill in the origin, just can freeze the agent for storage of coldness (10) of full case, need not electric power supply in transit.

Advantage of the present utility model and effect are as follows:

(1) if starts refrigerating unit with general 15～20 kilowatts of three-phase alternating-current supplies in the origin, once filled cold more than ten hours, just can freeze whole agent for storage of coldness in the case, transport in 5～7 days in the way and need not electric power supply, if fill can utilize night's rest halfway the time coldly, then haulage time and length of run can be multiplied.

(2) because use is nontoxic, nothing is corroded and the little colloid shape agent for storage of coldness of coefficient of expansion, there is not shock oscillation in the transportation, dynamic performance in service is good, compare with salt solution, avoided from safety valve, going out and the drawback of dirty cargo, and because the cold storage capacity of this agent for storage of coldness is big, than salt solution, under equal cold storage capacity requirement condition, weight reduces more than 20%, thereby has improved load carrying ability relatively.In addition,, can significantly reduce expansion volume, thereby reduce the cold drawing size, increase the cargo capacity relatively because colloid shape agent for storage of coldness coefficient of expansion only is 1/7 of a salt solution.As for characteristics such as nontoxic, pollution-free, favourable to food transport and environmental protection especially, avoided corrosion fully to facilities such as vehicle, rail and bridges.And once fill, the permanent use need not to change or the filling agent for storage of coldness.

(3) owing to can utilize ISO freight container to make shell, keep the commonality and the interchangeability of former case, and can realize " door t door " transportation, and FCL production, small investment, cost is low, estimates that price only is about half of similar machines refrigerated container.

(4) because above advantage is arranged, traffic cost reduces greatly.

Below in conjunction with the description of the drawings and embodiment, the utility model will be further described.
