Abstract
The utility model discloses a device for removing impurities of refrigerating fluid, and belongs to the technical field of filtration of refrigeration equipment. An existing refrigerating fluid filter device has the defects of being poor in filter effect and high in cost. The device for removing the impurities of the refrigerating fluid comprises a first copper pipe, a second copper pipe and a filter screen, one end of the first copper pipe is connected with a connecting sleeve, and the diameter of the inner hole wall of the connecting sleeve is slightly larger than the outer diameter of the first copper pipe and the outer diameter of the second copper pipe. The filter screen comprises a conical filter portion and a circular connecting portion, the circular connecting portion is arranged in the connecting sleeve, the filter portion penetrates through the connecting sleeve and is arranged in the first copper pipe, one end of the second copper pipe is arranged in the circular connecting portion in an inserting mode, and the first copper pipe, the filter screen and the second copper pipe are directly sealed and fixed with each other through welding. The filter screen is arranged on the joint portion of the two copper pipes, mounting is convenient, a producing and processing process is simple and producing cost is reduced. The filter screen is arranged to be conical, the flow of refrigerating fluid is enlarged, and filter speed and filter effect are improved.
Description
Technical field
The utility model belongs to the refrigeration plant filtration art, and is especially relevant with a kind of cold-producing medium impurities removing unit.
Background technology
In refrigeration system, usually contain impurity in the cold-producing medium, therefore need device for filtering impurities that the impurity in the cold-producing medium is filtered, prevent that the refrigeration system pipeline is blocked, make carrying out smoothly of whole refrigeration system, the existing filter that uses generally adopts two ends to have the copper pipe of adapter and places a short flat screen pack in the copper pipe, though can remove impurity to a certain extent, but the less flow of refrigerant that makes of flow area has some setbacks, and has reduced the flow of cold-producing medium, causes system's refrigerating efficiency lower; Though also have some filters can improve filter effect, structure more complicated, processing technology are difficult, the production cost height.
The utility model content
The purpose of this utility model is intended to overcome the existing defective that the refrigerant filtering apparatus filter effect is bad, cost is higher, and a kind of simple in structure, easy cold-producing medium impurities removing unit of processing and good filtration effect is provided.
For this reason, the utility model is by the following technical solutions: a kind of cold-producing medium impurities removing unit, it is characterized in that, described impurities removing unit comprises first copper pipe, second copper pipe and screen pack, described first copper pipe, one end is provided with adapter sleeve, adapter sleeve inner hole wall diameter is a bit larger tham the external diameter of first copper pipe and second copper pipe, described screen pack comprises conical filtering portion and annular connecting portion, the annular connecting portion is installed in the adapter sleeve, filter house passes adapter sleeve and is positioned at the first copper pipe pipe, described second copper pipe, one end is plugged in the described annular connecting portion, by freezing directly with first copper pipe, screen pack and the mutual sealing and fixing of second copper pipe.
As to technique scheme replenish and perfect, the utility model also comprises following technical scheme.
The internal diameter of described first copper pipe and second copper pipe is consistent respectively with external diameter.
Use the utility model can reach following beneficial effect: by screen pack being installed on two copper pipe joint places, easy for installation, production and processing technology is simple, has reduced production cost; Screen pack is arranged to taper, has strengthened the flow of cold-producing medium, improved the rate of filtration and filter effect.
