Description

Multi-temperature zone vibration proof refrigerating transport vehicle

Technical field

The utility model relates to Refrigerated Transport technical fields, more particularly to a kind of multi-temperature zone vibration proof refrigerating transport vehicle.

Background technique

Food fresh keeping is paid close attention to by more and more people now, the refrigerating transport vehicle tool important as Refrigerated Transport, It is an important ring for cold chain.Hold that perishable food species are also more and more in Refrigerated Transport industry, there is single fruit And vegetables, milk systems product development product, fish, shrimps, seafood, transportation range is being continuously increased, but these foods are transporting Required actual temp is different on the way, if being placed on different types of food in one refrigerator car without exception, presumable Food is in best storage temperature, and other food may not be best storage temperature.Or a refrigerator car is only stored together Food at a temperature of one, and refrigerated vehicle carriage is caused to have a large amount of vacant wastes for causing resource.Existing refrigerator car partitioning scenario It is to realize different storage temperature with air-cooler, causes the waste of temperature distributing disproportionation and resource.And during transportation Mechanical oscillation cause the very big loss of cargo.

Utility model content

The purpose of this utility model is to be directed to technological deficiency existing in the prior art, and providing one kind can store simultaneously The multi-temperature zone vibration proof refrigerating transport vehicle of food and reduction energy consumption and vibration loss under different refrigerated storage temperatures, to improve cold The efficiency of vehicle transport is hidden, economy is improved.

To realize that technical solution used by the purpose of the utility model patent is:

A kind of multi-temperature zone vibration proof refrigerating transport vehicle, including carriage body, the carriage body inside is by divides at three Warm area storeroom, respectively high-temperature region, middle warm area and low-temperature space, demarcation plate consist of three layers: first layer is vibration damping cotton, the second layer It is steel plate, third layer is evaporator；Peripheral barrier positioned at four wall of carriage body is made of outer wall insulating layer and internal layer evaporator: described Carriage body is equipped with refrigerant input main pipe and refrigerant-recovery main pipe,

The part that each demarcation plate and peripheral barrier are connected with main pipe is connect using hose, and rest part and refrigeration system connect It connects and is connected using copper pipe,

Refrigerant inputs at least three groups of evaporator refrigeration pipelines in parallel between main pipe and refrigerant-recovery main pipe, every group of evaporation Device refrigeration piping is by sequentially connected electric expansion valve, evaporator, pressure sensor, temperature sensor and evaporating pressure regulating valve Composition,

The pressure sensor and temperature sensor are separately connected automatic control system, and it is swollen that automatic control system adjusts electronics The opening degree of swollen valve.

Wherein each warm area is divided into three specifically by the way that demarcation plate is arranged according to the difference of institute's reserve temperature requirement Temperature layer.

Compared with prior art, the utility model has the beneficial effects that

1, the multi-temperature zone refrigerating transport vehicle of the utility model is being divided into high-temperature region, middle warm area and low-temperature space, adopts between each area It being connected with demarcation plate, same area can be divided into three floor again, and the food of different storage temperature is realized in same refrigerator car while being transported, It improves economical.

2, the material of demarcation plate first layer is vibration damping cotton, and less refrigerator car is because of damage caused by jolting food.

3, senior middle school's low-temperature space is respectively divided into three parts refrigeration again according to different storage temperature by refrigerator car, is equivalent to and is divided into Nine warm areas thus may be implemented the food for storing nine kinds of different refrigerated storage temperatures simultaneously, refrigerator car avoided to reach because of refrigerated storage temperature Less than, and caused by carriage body it is vacant, make full use of compartment space.

4, evaporator and the branch pipeline of main pipe coupling part are connected using hose, in this way can according to reserve number And the position of separate layer is moved up and down, it is more convenient.

5, evaporator outlet is equipped with pressure sensor and temperature sensor, can adjust electronics by automatic control system The opening degree of expansion valve makes the benefit entirely recycled reach highest to reach the optimal degree of superheat.

Fig. 3 is the internal structure chart of separate layer；

Fig. 4 is the structure chart of peripheral barrier.

Specific embodiment

The utility model is described in further detail below in conjunction with the drawings and specific embodiments.

The schematic diagram of the utility model multi-temperature zone vibration proof refrigerating transport vehicle is as shown in Figure 1, be divided into three areas, high-temperature region 1, Middle warm area 2, low-temperature space 3, peripheral barrier 4, demarcation plate 5, the structure of demarcation plate is as shown in figure 3, first layer is vibration damping cotton 23, purpose It is to reduce food jolting during transportation, the second layer is steel plate 24, is played a supporting role, and third layer is evaporator 25, is reached To the effect of refrigeration.As shown in figure 4, be located at four wall of carriage body peripheral barrier kept the temperature by outer wall, 26 and internal layer evaporator 27 constitute: Separating laminate can need to move up and down.In Fig. 2, refrigerant input between main pipe 10 and refrigerant-recovery main pipe 11 it is in parallel at least Three groups of evaporator refrigeration pipelines, every group of evaporator refrigeration pipeline are electric expansion valve 6, export direction evaporator direction It is pressure sensor 7, temperature sensor 8, evaporating pressure regulating valve 9.Evaporator in each demarcation plate and peripheral barrier is exactly Evaporator in one group of evaporator refrigeration pipeline；It is passed in automatic control system by pressure sensor and temperature sensor, so The degree of superheat for calculating circulation by control system afterwards, according to the opening degree of the big minor adjustment electric expansion valve of the degree of superheat, from And the refrigerant into evaporator is preferably controlled, reach the efficient utilization of the energy.

It is required according to difference of the different cargos to temperature, cargo is placed in corresponding warm area storeroom protects respectively It deposits, a variety of different foods can be stored simultaneously, the intracorporal space in compartment is made to be fully used.

The above is only the preferred embodiment of the utility model, it is noted that for the general of the art For logical technical staff, without departing from the principle of this utility model, several improvements and modifications can also be made, these change It also should be regarded as the protection scope of the utility model into retouching.
