Description

Cold hydrazine structure

Technical Field

The utility model belongs to the technical field of the diesel oil detects technique and specifically relates to a be used for refrigerating and maintain microthermal cold hydrazine structure in the testing process.

Background

The diesel cold filter plugging point is the lowest temperature at which a diesel sample is cooled under specified conditions, pumped at a pressure of 1961Pa (200 mm water column), the cooled diesel sample is passed through a 363 mesh filter, and the filter is plugged to fail or the flow rate is less than 20 ml/min. The lower the temperature, the better the flowability of the diesel fuel at low temperatures and the less likely it is to clog the filter. Therefore, the cold filter plugging point is one of the important indexes in the diesel specification.

The existing diesel oil cold filter plugging point measuring instrument generally comprises a suction filtration device and a refrigerating device, but the refrigerating device mostly adopts a compressor refrigerating mode which has the following advantages: 1) the equipment for refrigerating by the compressor is simple to produce and manufacture, low in manufacturing cost and simple to use and maintain, so that the equipment has ultra-high performance-price ratio; 2) the compressor is convenient to refrigerate and maintain, the maintenance period is relatively long, and the requirement of long-time maintenance-free use can be met; 3) the compressor has various types, and the most suitable type of compressor can be reasonably selected according to actual requirements; 4) certain compressors can easily realize high compression ratio work, can easily realize large refrigerating capacity, can realize stepless regulation according to actual requirements, and are easy to control. But the disadvantages are also quite obvious: 1) the power consumption is the biggest shortcoming of compressor refrigeration, and under normal conditions, the energy loss of a large-scale compressor can reach 5% -20%, although the power consumption of a small-scale compressor is small, the power consumption is still very surprise due to wide application and large quantity; 2) the problem that working media are easy to leak in many machine types is limited by the structure of the compressor, irreversible damage is easy to cause to the environment, and the high compression ratio of the machine is difficult to realize due to the reason; 3) the compressor type refrigerator is usually accompanied with larger vibration and noise when in work, which also has larger limitation on the service life of the compressor type refrigerator; 4) many complete machines are large in size and weight, light-weight production is difficult, wearing or portable requirements cannot be met, and therefore military application markets are difficult to impact.

Later, people adopted Stirling refrigerators with simple structures, but the original cold conduction structure is complex and the cold conduction speed is slow.

Therefore, the skilled person is working to develop a cold trap structure with simple structure and rapid cold conduction.

Disclosure of Invention

In view of the above-mentioned defects in the prior art, the technical problem to be solved in the present invention is to provide a cold trap structure with simple structure and capable of rapidly conducting cold.

In order to achieve the purpose, the utility model provides a cold trap structure, which comprises a first refrigeration sleeve and a second refrigeration sleeve which are vertically arranged, wherein the top of the first refrigeration sleeve is opened, and the bottom of the first refrigeration sleeve is sealed; one end of the second refrigeration sleeve is open, and the other end of the second refrigeration sleeve is sealed and welded on the side wall of the first refrigeration sleeve.

And a solid saddle-shaped heat conduction part is also arranged between the second refrigeration sleeve and the first refrigeration sleeve.

The saddle-shaped heat conducting parts are provided with two parts which are respectively positioned at the upper end and the lower end of the first refrigeration sleeve.

The width of the saddle-shaped heat conducting part is equal to the diameter of the second refrigeration sleeve.

The top of the saddle-shaped heat conducting part at the upper end is flush with the top of the first refrigeration sleeve, and the bottom of the saddle-shaped heat conducting part at the lower end is flush with the bottom of the first refrigeration sleeve.
