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

[0044] Such as figure 1 As shown, in this embodiment, the center of the first filter screen 2 is provided with a first passage 4 directly connecting the first chamber 13 and the second chamber 14, and the first passage 4 is provided with an openable and closable The first one-way valve 6; the center of the second filter screen 3 is provided with a second passage 5 directly connecting the second chamber 14 and the third chamber 15, and the second passage 5 is provided with an openable and closable The second one-way valve 7. By being respectively provided with a first one-way valve and a second one-way valve on the first filter screen and the second filter screen, the first chamber 13 or the third chamber 15 chambers are independently communicated with the second chamber 12, so that the second chamber The filter residue retained by a 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 in...

Embodiment 2

[0049] 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 dry filter housing.

[0050] 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 th...

Embodiment 3

[0056] 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 .

[0057] 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.

[0058] 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 bidirectional drying filter capable of collecting impurities and a heat pump system. The bidirectional drying filter comprises a shell. A first opening and a second openingare formed in the two opposite ends of the shell correspondingly; a first filter screen and a second filter screen are arranged in the shell and divide the interior of the shell into three chambers which are independent of one another and sequentially distributed from the first opening of the shell to the second opening of the shell; channels enabling the chambers in the two sides to communicate are formed in the first filter screen and the second filter screen correspondingly; and control valves for controlling on-off are arranged at the channels correspondingly. In this way, media can flow into the filter from the two ends of the filter and are dried and filtered sequentially, and thus the media switching the flowing directions with one another are filtered; and meanwhile, in the processthat the flowing media are filtered by the filter, the on-off states of the channels in the first filter screen and the second filter screen are switched correspondingly along with the flowing directions of the media, and thus the filtered impurities are reserved between the two filter screens.

Description

technical field [0001] The present invention relates to a two-way dry filter capable of collecting impurities, and also to a heat pump system equipped with the above-mentioned two-way dry filter; in particular, to a heat pump water heater applying the above-mentioned heat pump system equipped with the two-way dry filter. 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 ...
