A kind of temperature zoning type cold box and standardized cold box system

Abstract

The invention discloses a temperature partitioned type refrigerator and a standard refrigerator system. The temperature partitioned type refrigerator comprises a box body and a telescopic sliding type goods shelf, wherein the telescopic sliding type goods shelf is mounted in the box body; the telescopic sliding type goods shelf comprises at least two heat preserving plates which are vertically arranged, the upper and lower ends of the heat preserving plates are separately pressed against the top and bottom inner walls of the box body, moving structures are arranged between the heat preserving plates and the top and bottom inner walls of the box body, and the heat preserving plates can transversely move in the box body; at least one layer of goods shelf sliding grooves are formed in the two side surfaces of each heat preserving plate, at least one layer of goods shelf sliding grooves are further arranged in the two side walls close to a refrigerator door of the box body, and the goods shelf sliding grooves in the side walls of the box body correspond to the goods shelf sliding grooves in the heat preserving plates; and telescopic goods shelves are mounted between the goods shelf sliding grooves in the side walls of the box body and the goods shelf sliding grooves in the heat preserving plates or between the goods shelf sliding grooves of the two adjacent heat preserving plates, and the telescopic goods shelves can extend or retract in a direction perpendicular with the goods shelf sliding grooves.

Description

technical field [0001] The invention specifically relates to a temperature partition type cold box and a standardized cold box system. Background technique [0002] The development level of cold chain logistics is affected by many factors, among which the quality of refrigerated transportation equipment is an important restrictive factor. The existing refrigerated vehicles have the following problems: [0003] (1) The temperature of the cold box is single [0004] Different types of goods have different temperature requirements. In today's cold chain transportation and distribution links, no matter whether it is a refrigerated truck, a special cold chain box, or an ice bag, it can only maintain a single temperature. Mixing goods that require different temperatures at one temperature will greatly reduce the freshness of fresh food; separately loading them in different cold boxes for transportation will reduce the efficiency of transportation and distribution, causing great d...

Problems solved by technology

Mixing goods that require different temperatures at one temperature will greatly reduce the freshness of fresh food; separately loading them in different cold boxes for transportation will reduce the efficiency of transportation and distribution, causing great damage to cold chain transportation equipment. big waste

[0005] (2) Unreasonable utilization of refrigerated truck space

[0006] In the cold chain transportation, there is basically no detailed space planning. In order to maintain the refrigerated temperature of the frozen goods, the goods are tightly stacked on the bottom plate of the cold box, which reduces the utilization rate of the cold storage space.

At the same time, the goods are squeezed against each other and the loss is large, which cannot ensure that the goods are in good condition and increases the loss of the goods.

[0007] (3) It is greatly affected by the season

[0009] (4) Large energy consumption

[0010] At present, the existing cold chain low-temperature distribution vehicles of most domestic cold chain logistics companies basically use refrigerated truck refrigerating units or dry ice refrigeration. Relevant data show that refrigerated truck refrigerating units consume 2 to 4 liters of fuel per 100 kilometers. Exhaust emissions increased by more than 30%, energy consumption, environmental protection and other issues seriously hindered the full development of cold chain transportation
