Description

Technical Field

[0001] This utility model relates to the field of copper filter technology, specifically to a copper filter with multi-stage composite filtration function. Background Technology

[0002] Copper filters are key components in refrigeration systems used to adsorb moisture and remove impurities from refrigerants. They mainly consist of copper tubes, molecular sieves, and filtration devices. The outer shell is formed by the constriction of copper tubes, and the inlet and outlet ports at both ends are of two different diameters: the inlet port has a coarse metal mesh, and the outlet port has a fine metal mesh. They can effectively filter impurities and are widely used in refrigeration equipment such as air conditioners, heat pumps, and freezers to ensure stable system operation.

[0003] After the copper filter has been adsorbing impurities and moisture in the refrigeration system for a long time, the filter screen will also adsorb impurities and moisture from the refrigeration system. As the amount of adsorption increases, it will affect the gas flow rate, so the filter screen inside the copper filter needs to be cleaned or replaced.

[0004] Traditional copper filter housings are mostly integral, with only a single metal mesh inside. This results in poor filtration efficiency, and because the housing is integral, the internal filter is difficult to clean and requires frequent replacement, increasing the maintenance costs of the air conditioning system. Utility Model Content

[0005] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a copper filter with multi-stage composite filtration function, which can effectively solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: This utility model provides a copper filter with multi-stage composite filtration function, comprising: A copper outer shell, with a gas inlet pipe fixedly connected to one side of the copper outer shell and a gas outlet pipe fixedly connected to the other side of the copper outer shell; The filtration mechanism includes three filter screens installed at equal intervals on the inner wall of a copper shell, and the filtration accuracy of the three filter screens varies in a gradient. The cleaning mechanism includes a connecting pipe fixedly connected to the outside of the gas outlet pipe, a third valve installed at the other end of the connecting pipe, an air inlet pipe installed at the other port of the third valve, and three branch pipes evenly distributed at the bottom of the copper outer shell, with the other end of each branch pipe connected to the same drain pipe.

[0007] Preferably, an upper guide plate is fixedly connected to the inner wall of the copper outer shell, and the upper guide plate is bent downward on the side near the filter screen.

[0008] Preferably, a lower guide plate is fixedly connected to the inner wall of the copper outer shell, and the lower guide plate is bent downward on the side near the filter screen.

[0009] Preferably, a hot air duct that communicates with the inside of the air inlet duct is fixedly connected to the outside of the air inlet duct.

[0010] Preferably, one end of each of the three branch pipes near the copper outer shell is connected to the inside of the copper outer shell, and a second valve is provided in the middle of each of the three branch pipes.

[0011] Preferably, a first valve is provided between the gas inlet pipe and the gas outlet pipe.

[0012] The technical solution provided by this utility model has the following advantages compared with the known prior art: 1. This utility model, by setting up a filtration mechanism, has three equally spaced filter screens with different filtration precisions inside the copper shell. This allows the copper filter to filter impurities of different sizes in the refrigeration system separately, improving the filtration effect of the copper filter. Furthermore, under the action of the upper and lower guide plates, the incoming airflow is guided to flow from top to bottom, cleaning the debris adsorbed on the outside of the filter screen, effectively reducing the frequency of filter screen cleaning.

[0013] 2. This utility model, by setting up a cleaning mechanism, eliminates the need to disassemble the copper casing when cleaning the filter screen inside the casing. By using reverse flushing of gas, the impurities adsorbed on the filter screen can be cleaned. The cleaned impurities can be discharged through the drain pipe, making the cleaning operation convenient and quick. Furthermore, after cleaning the filter screen, hot air at a suitable temperature can be injected into the copper casing to dry the filter screen inside the casing, ensuring its filtration effect on the refrigeration system.

Detailed Implementation

[0017] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0018] The present invention will be further described below with reference to the embodiments.

[0019] Example 1: Reference Figure 1-3 This is the first embodiment of the present invention, which discloses a copper filter with multi-stage composite filtration function, comprising: A copper outer shell 1, a gas inlet pipe 4 is fixedly connected to one side of the copper outer shell 1, and a gas outlet pipe 3 is fixedly connected to the other side of the copper outer shell 1; With the help of the gas inlet pipe 4 and the gas outlet pipe 3, the copper filter can be connected to the air duct of the air conditioning refrigeration system. The gas in the refrigeration system enters through the gas inlet pipe 4, and after being filtered by the three filter screens 501, it is discharged through the gas outlet pipe 3.

[0020] The filtration mechanism 5 includes three filter screens 501 installed at equal intervals on the inner wall of the copper outer shell 1, and the filtration accuracy of the three filter screens 501 varies in a gradient.

[0021] The filter screen 501 is welded to the inner wall of the copper outer shell 1, and the precision of the three filter screens 501 increases from the gas inlet pipe 4 to the gas outlet pipe 3.

[0022] Specifically, an upper guide plate 502 is fixedly connected to the inner wall of the copper outer shell 1. The side of the upper guide plate 502 near the filter screen 501 is bent downwards. A lower guide plate 503 is fixedly connected to the inner wall of the copper outer shell 1. The side of the lower guide plate 503 near the filter screen 501 is bent downwards.

[0023] With the cooperation of the upper guide plate 502, the lower guide plate 503, and the copper shell 1, a gas flow channel is formed, so that after the gas enters the interior of the copper shell 1, it flows from top to bottom under the guidance of the upper guide plate 502 and the lower guide plate 503, cleaning the debris adsorbed on the outside of the filter screen 501.

[0024] Example 2: Reference Figure 1-4 This is the second embodiment of the present invention, which differs from the first embodiment in that: The cleaning mechanism 2 includes a connecting pipe 202 fixedly connected to the outside of the gas outlet pipe 3. A third valve 203 is installed at the other end of the connecting pipe 202. An air inlet pipe 204 is installed at the other interface of the third valve 203. Three branch pipes 208 distributed at equal intervals are fixedly connected to the bottom of the copper shell 1. The other end of the branch pipes 208 is connected to the same sewage pipe 206.

[0025] The third valve 203 can control the opening and closing of the connecting pipe 202. The air inlet pipe 204 can inject gas into the copper shell 1 through the third valve 203 and the connecting pipe 202 to reverse clean the dust adsorbed on the filter screen 501 and make it enter the branch pipe 208 at the corresponding position.

[0026] Specifically, a hot air pipe 205 that communicates with the inside of the air inlet pipe 204 is fixedly connected to the outside of the air inlet pipe 204.

[0027] The hot air duct 205 can work with the air inlet duct 204 to inject hot gas into the copper casing 1. The hot gas dries the moisture adsorbed on the filter screen 501 inside the copper casing 1. The dried gas carries the water vapor and is discharged through the branch pipe 208, thus drying the filter screen 501 and ensuring the filtration effect of the filter screen 501 on the gas in the refrigeration system.

[0028] Specifically, the three branch pipes 208 are connected to the inside of the copper outer shell 1 at the end closest to the copper outer shell 1, and a second valve 207 is provided in the middle of each of the three branch pipes 208.

[0029] The second valve 207 controls the opening and closing of the branch pipe 208. When the filter screen 501 needs to be cleaned, the branch pipe 208 is opened, and it is closed when the copper filter is working, ensuring that a sealed space is formed inside the copper shell 1 to ensure the flow rate of gas.

[0030] Specifically, a first valve 201 is installed between the gas inlet pipe 4 and the gas outlet pipe 3.

[0031] The opening and closing of the gas inlet pipe 4 and the gas outlet pipe 3 can be controlled by the first valve 201. When it is necessary to clean the filter screen 501 inside the copper shell 1, the gas inlet pipe 4 and the gas outlet pipe 3 can be closed to prevent the cleaning gas from entering the air conditioning refrigeration system.

[0032] The remaining structure is the same as that in Example 1.

[0033] The workflow of this utility model is as follows: Under the action of gas inlet pipe 4 and gas outlet pipe 3, the copper filter is connected to the air conditioning refrigeration system. Gas enters the interior of the copper shell 1 through gas inlet pipe 4. Three filter screens 501 with different precision filter impurities and moisture in the gas. The filtered gas is discharged through gas outlet pipe 3 and re-enters the refrigeration system. When it is necessary to clean the filter screen 501 inside the copper shell 1, the first valve 201 controls the closure of the gas inlet pipe 4 and the gas outlet pipe 3, while the second valve 207 and the third valve 203 control the opening of the branch pipe 208 and the connecting pipe 202. The air supply equipment connected to the air inlet pipe 204 injects clean gas into the copper shell 1 through the air inlet pipe 204. The clean gas enters and cleans the dust adsorbed on the filter screen 501 from the reverse direction. The cleaned dust is discharged through the branch pipe 208 and the drain pipe 206 under the action of the airflow. Then, hot gas is injected into the copper casing 1 through the hot air pipe 205. After entering the copper casing 1, the hot gas dries the moisture adsorbed on the filter screen 501 inside the copper casing 1. The water vapor generated during drying is discharged from the copper casing 1 through the branch pipe 208 and the drain pipe 206 with the airflow. After the filter screen 501 is cleaned, the branch pipe 208 and the connecting pipe 202 are closed by the second valve 207 and the third valve 203, and the gas inlet pipe 4 and the gas outlet pipe 3 are opened by the first valve 201, thus completing the cleaning of the filter screen 501 inside the copper casing 1.

[0034] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
