Problems solved by technology

During the production and maintenance process of the product, the water vapor in the air will be brought into the refrigerant, and ice crystals will be formed in the pipeline with the flow of the refrigerant, which will affect the overall performance of the machine. Therefore, the existing detachable cleaning and one-way filter It is not suitable for this situation, and cannot solve the problem of drying and filtering the cold medium in the heat pump system
[0004] In addition, the existing filters capable of bidirectional filtration are generally provided with at least 4 one-way valves, which cannot be applied to refrigerant systems due to their complex structure and failure to meet economical requirements.
At the same time, the two-way filter in the prior art can not control and collect the filter residue while realizing the two-way filtration, so that the filter residue moves in circulation at both ends of the filter and interferes with other components of the system

Embodiment 1

[0046] Such as figure 1 As shown, in the present embodiment, the center of the first filter screen 2 is provided with the first passage 4 directly connecting the first chamber 13 and the second chamber 14, and the center of the second filter screen 3 is provided with the second chamber Chamber 14 and the second passage 5 that the third chamber 15 directly communicates; The first passage 4 and the second passage 5 place are provided with a public reversing valve 6, make the first chamber 13 or the third chamber 15 chamber Separately communicate with the second chamber 12, so that the filter residue retained by the first filter screen 2 flows into the second chamber 14 from the first channel 4, or the filter residue retained by the second filter screen 3 flows into the second chamber from the second channel 5. Chamber 14.

[0047] In this embodiment, the first channel 4 and the second channel 5 are coaxially spaced apart, and the spool 61 of the reversing valve 6 is arranged be...

Embodiment 2

[0052] In this embodiment, the shell 1 of the two-way dry filter includes a cylindrical side wall 10, and the two ends of the cylindrical side wall 10 are respectively the opposite first end and the second end of the shell 1; the two ends of the cylindrical side wall 10 are respectively There are side plates that are sealed and connected, the first end side plate is correspondingly provided with a first opening 11, and the second end side plate is provided with a second opening 12, so that both ends of the siege can be used as outlets or as outlets. Imported two-way filter housing.

[0053] In this embodiment, the cylindrical side wall 10 of the housing 1 is provided with a first filter screen 2 and a second filter screen 3 arranged at intervals, and the inside of the housing between the first filter screen 2 and the first end side plate is the second filter screen. A chamber 13, the inside of the shell between the first filter screen 2 and the second filter screen 3 is the se...

Embodiment 3

[0059] Such as figure 2 As shown, in the present embodiment, a plurality of support bars 22 are arranged radially along the tapered filter screen 20, and the two ends of each support bar 22 are fixedly connected with the upper support ring 21 and the lower support ring 23 respectively, and each support bar 22 is fixed in contact with the side of the conical filter screen 20 close to the second chamber 14 .

[0060] By arranging a plurality of support bars 22 extending in the radial direction of the conical filter screen 20, multiple parts of the filter screen are fixedly connected to the support bars 22 respectively, so as to improve the fixing degree of the filter screen and avoid the situation that the filter screen is impacted and falls off. Occurs to enhance the filtering effect of the filter.

[0061] Preferably, the support bars 22 are arranged at equal intervals relative to the center of the conical filter screen 20, so that the support bars 22 are evenly distributed ...

Abstract

The invention relates to a two-way filter and a heat pump system capable of collecting impurities. The filter includes a shell, and a first opening and a second opening are respectively arranged at opposite ends of the shell; a first filter screen and a second filter screen are arranged inside the shell , the first filter screen and the second filter screen divide the inside of the housing into three chambers that are independent of each other and are arranged sequentially from the first opening of the housing to the second opening; the first filter screen and the second filter screen There are passages connecting the chambers on both sides respectively on the net, and a common control valve is arranged at the two passages to control the on-off of the two passages. Through the above settings, the medium can flow into the filter from both ends of the filter respectively, and perform filtration treatment, so as to achieve the purpose of secondary filtration treatment for the medium that switches the flow direction; at the same time, the filter passes through the medium. During the process, the opening and closing states of the channels on the first filter screen and the second filter screen are switched correspondingly with the flow direction of the medium, so that the filtered impurities are retained between the two filter screens.

Description

technical field [0001] The present invention relates to a filter, in particular to a two-way filter capable of collecting impurities, and also to a heat pump system equipped with the above-mentioned two-way filter; Heat pump water heater. Background technique [0002] The filter is an indispensable device on the conveying medium pipeline, and is usually installed at the inlet end of other equipment such as pressure reducing valves, pressure relief valves, and water level valves. The filter is a filter cartridge with a filter screen of a certain specification inside, so that the impurities contained in the medium flowing into the filter cartridge are blocked by the filter screen, so as to achieve the purpose of filtering the medium flowing through. [0003] At present, the commonly used filters are mainly one-way Y-type filters. When there are many filter residues and continuous filtration of clean fluid, the filter screen needs to be cleaned; In the flow path, the filter d...
