Description

Technical Field

[0001] The present application relates to the technical field of water cooling machines, and in particular to a screw type water cooling unit. Background Art

[0002] A water-cooled unit, also known as a chiller, is a type of cooling water equipment that can provide constant temperature, constant flow and constant pressure. A screw water-cooled unit is a type of common water-cooled machine. A screw chiller is a chiller that uses a screw compressor. The screw chiller has a large refrigeration power. A screw chiller is generally provided with water inlet and outlet pipes. As water enters the inlet pipe and flows out of the outlet pipe, the inlet water temperature is generally greater than the outlet water temperature, thereby achieving a cooling effect.

[0003] The utility model patent with announcement number CN218934724U proposes a screw water cooling unit, including a screw chiller body, a water inlet pipe arranged on the screw chiller body and a water outlet pipe arranged on the screw chiller body, the water inlet pipe is provided with a filtering device for filtering water, the filtering device includes a delivery pipe, a conducting pipe is fixedly installed on the delivery pipe, a filter pipe is connected to the end flange of the conducting pipe, a filter screen is fixedly installed on the inner wall of the filter pipe, a hard pipe is connected to the end flange of the filter pipe, and the hard pipe is flange-connected to the water inlet pipe.

[0004] The above-mentioned water-cooled unit filters the cold water by setting a filtering device. When there are many impurities retained on the filtering device, a backwashing water pump is used for backwashing to prevent the impurities in the cold water from being deposited in the serpentine pipe of the water-cooled unit, thereby affecting the cold water transportation and refrigeration effect.

[0005] The above-mentioned water-cooling unit needs to close the second valve when backwashing to clean impurities. During the cleaning process, the water-cooling unit cannot perform refrigeration normally, which makes it very inconvenient for users to use. Utility Model Content

[0006] The utility model aims to solve or at least alleviate the problem that the existing water cooling unit needs to close the second valve when backwashing to clean impurities, and the user cannot refrigerate normally during the cleaning process, causing great inconvenience to the user.

[0007] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0008] A screw-type water-cooling unit comprises a water-cooling unit body equipped with a water inlet pipe and a drain pipe, the water inlet pipe being connected to a filter pipe at one end away from the water-cooling unit body through a connecting piece, a filter structure being obliquely installed in the inner cavity of the filter pipe, a sewage pipe connected to the inner cavity of the filter pipe being obliquely installed on one side of the filter pipe, the bottom wall height of the inner cavity of the sewage pipe being flush with the upper surface height of the end with the lower height of the filter structure, a ball valve being installed at the connection between the sewage pipe and the filter pipe, the sewage pipe being detachably connected to a sealing assembly at one end away from the filter pipe, a return water pipe being perpendicular to the sewage pipe being provided below the middle section of the sewage pipe, the two ends of the return water pipe being respectively connected to the sewage pipe and the inner cavity of the filter pipe, and a second filter screen being embedded in the inner cavity of the end where the return water pipe is connected to the sewage pipe.

[0009] By adopting the above technical solution, when using, the user first connects the filter tube to the water inlet pipe through the flange and bolts, and then introduces cold water into the filter tube. Since the first filter screen is obliquely installed in the filter tube to filter impurities, when the impurities are blocked by the filter structure, under the impact of the water flow, the impurities slide into the inner cavity of the sewage storage pipe along the filter structure for storage, and the water flow passes through the second filter screen and flows back to the bottom of the filter tube through the return pipe, and finally enters the water cooling unit body along the water inlet pipe for refrigeration. When there are many impurities in the sewage storage pipe, the user can close the ball valve so that the clean water and impurities in the filter tube cannot enter the sewage storage pipe temporarily, and then the user opens the sealing component to clean the impurities in the sewage storage pipe. After cleaning, the user closes the sealing component again and opens the ball valve, so that the impurities can be collected through the sewage storage pipe again. When cleaning the impurities, the use of the water cooling unit body is not affected, and the need to close the second valve when cleaning the impurities is avoided as much as possible. The user cannot refrigerate normally during the cleaning process, which causes the user to use it very inconveniently.

[0010] Optionally, the connecting member includes a flange welded between adjacent ends of the water inlet pipe and the filter tube, a plurality of bolts are passed through the flange, and the water inlet pipe is threadedly connected to the filter tube through the flange and the bolts.

[0011] By adopting the above technical solution, flanges and bolts are provided to connect the water inlet pipe and the filter pipe together, and a threaded connection method is adopted, which not only ensures a stable connection, but also facilitates installation and disassembly by users.

[0012] Optionally, the filtering structure is a first filter screen with an elliptical structure embedded in the inner cavity of the filter tube, and the peripheral side of the first filter screen is fixedly connected to the inner wall of the filter tube.

[0013] By adopting the above technical solution, a first filter is set to filter impurities in the cold water passing through the filter tube, thereby preventing impurities in the cold water from entering the water-cooling unit and being deposited in the serpentine pipe of the water-cooling unit, thereby affecting the cold water transportation and refrigeration effect.

[0014] Optionally, the sealing assembly is an end cap screwed onto one end of the dirt storage tube away from the filter tube, and an anti-slip groove is provided on the outer surface of the end cap.

[0015] By adopting the above technical solution, an end cover is provided to seal the free end of the sewage storage pipe to prevent cold water from being discharged directly through the sewage storage pipe. An anti-slip groove is provided on the end cover to increase the friction force of the outer surface of the end cover, making it convenient for users to screw the end cover to install or remove the end cover.

[0016] Optionally, two groups of downwardly inclined baffles are provided in the inner cavity of the sewage storage pipe at one end of the ball valve close to the end cover, and the multiple baffles in the two groups are symmetrically arranged and alternately distributed.

[0017] By adopting the above technical solution, a plurality of alternately distributed baffles are provided to block impurities in sewage, so as to prevent impurities falling into the sewage storage pipe from flowing back into the inner cavity of the filter tube under the impact of water flow.

[0018] Optionally, a plurality of angle irons are welded to the circumference of one end of the sewage storage pipe and the water return pipe connected to the filter pipe.

[0019] By adopting the above technical solution, angle irons are welded at the connection between the sewage pipe, the return pipe and the filter pipe to improve the stability of the connection between the sewage pipe, the return pipe and the filter pipe, and to avoid the problem of the sewage pipe and the return pipe being broken by the impact of water flow as much as possible.

[0020] In summary, the beneficial effects of this application are as follows:

[0021] The present application coordinates the structures such as the filter tube, the sewage storage tube, the first filter screen, the second filter screen and the ball valve. When cleaning impurities, the ball valve can be closed to prevent the clean water and impurities in the filter tube from entering the sewage storage tube temporarily. Then the user opens the sealing component to clean the impurities inside the sewage storage tube. After cleaning, the user closes the sealing component again and opens the ball valve to collect impurities through the sewage storage tube again. The use of the water-cooling unit main body is not affected when cleaning impurities. The need to close the second valve when cleaning impurities is avoided as much as possible. The user cannot perform refrigeration normally during the cleaning process, which causes great inconvenience to the user. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] The following is combined with Figure 1-3 This application is described in further detail.

[0027] See also Figure 1-3 A screw-type water-cooling unit includes a water-cooling unit body 1 equipped with a water inlet pipe 2 and a drain pipe 3. When in use, the user injects cold water into the water-cooling unit body 1 through the water inlet pipe 2. The water-cooling unit body 1 uses a screw compressor to cool the water, and the water temperature is lowered and then discharged through the drain pipe 3. The water-cooling unit is an existing conventional technology and will not be described in detail here.

[0028] One end of the water inlet pipe 2 away from the water cooling unit body 1 is connected to the filter tube 4 through a connecting piece. A filtering structure is installed obliquely in the inner cavity of the filter tube 4. The cold water needs to pass through the filter tube 4 before entering the water inlet pipe 2. The impurities in the cold water are filtered by the filtering structure installed in the filter tube 4 to prevent the impurities in the cold water from being deposited in the serpentine pipe of the water cooling unit, which affects the cold water transportation and refrigeration effect.

[0029] A sewage storage pipe 7 connected to the inner cavity of the filter tube 4 is installed on one side of the filter tube 4 at an angle downward. The bottom wall height of the inner cavity of the sewage storage pipe 7 is flush with the upper surface height of the lower end of the filter structure. When impurities are blocked by the filter structure, under the impact of the water flow, the impurities slide along the filter structure into the inner cavity of the sewage storage pipe 7 for storage, thereby preventing impurities from accumulating at the filter structure and affecting the water supply to the water-cooling unit body 1.

[0030] A ball valve 10 is installed at the connection between the sewage storage pipe 7 and the filter tube 4. The end of the sewage storage pipe 7 away from the filter tube 4 is detachably connected with a sealing component. When the user needs to clean the impurities inside the sewage storage pipe 7, the ball valve 10 can be closed to prevent the clean water and impurities in the filter tube 4 from entering the sewage storage pipe 7 temporarily. Then the user opens the sealing component to clean the impurities inside the sewage storage pipe 7. After cleaning, the user closes the sealing component again and opens the ball valve 10, so that the impurities can be collected through the sewage storage pipe 7 again.

[0031] A return pipe 12 is provided below the middle section of the sewage pipe 7, which is perpendicular to the sewage pipe 7. Both ends of the return pipe 12 are respectively connected to the sewage pipe 7 and the inner cavity of the filter pipe 4. A second filter screen 13 is embedded in the inner cavity of one end of the return pipe 12 connected to the sewage pipe 7. The cold water entering the sewage pipe 7 along with the impurities can flow back to the filter pipe 4 through the return pipe 12, and enter the water cooling unit body 1 through the water inlet pipe 2, while the impurities in the sewage pipe 7 are blocked by the second filter screen 13 and are retained and stored in the sewage pipe 7.

[0032] Reference Figure 1 The connecting piece includes a flange 5 welded at one end of the water inlet pipe 2 and the filter pipe 4, and a plurality of bolts 6 are passed through the flange 5. The water inlet pipe 2 is screwed to the filter pipe 4 through the flange 5 and the bolts 6. The flange 5 and the bolts 6 are used to connect the water inlet pipe 2 and the filter pipe 4 together. The screw connection method is adopted, which is not only stable, but also convenient for users to install and disassemble.

[0033] Reference Figure 1 The filtering structure is a first filter screen 8 in an elliptical structure embedded in the inner cavity of the filter tube 4, and the periphery of the first filter screen 8 is fixedly connected to the inner wall of the filter tube 4. The first filter screen 8 is used to filter impurities in the cold water passing through the filter tube 4, to prevent the impurities in the cold water from entering the water cooling unit and being deposited in the serpentine pipe of the water cooling unit, thereby affecting the cold water transportation and refrigeration effect.

[0034] Reference Figure 2 The sealing component is an end cap 9 screwed on the end of the dirt storage pipe 7 away from the filter tube 4, and an anti-skid groove is provided on the outer surface of the end cap 9. The end cap 9 is used to seal the free end of the dirt storage pipe 7 to prevent cold water from being discharged directly through the dirt storage pipe 7. The anti-skid groove is provided on the end cap 9 to increase the friction force on the outer surface of the end cap 9, making it convenient for users to screw the end cap 9 to install or remove the end cap 9.

[0035] Reference Figure 3 Two groups of downwardly inclined baffles 11 are provided in the inner cavity of the sewage storage pipe 7 near the end of the end cover 9 of the ball valve 10. The multiple baffles 11 in the two groups are symmetrically arranged and alternately distributed. The multiple alternately distributed baffles 11 are used to block impurities in the sewage and try to prevent the impurities that fall into the sewage storage pipe 7 from flowing back into the inner cavity of the filter tube 4 under the impact of the water flow.

[0036] Reference Figure 1 A plurality of angle irons 14 are welded around the ends of the sewage pipe 7 and the return pipe 12 connected to the filter pipe 4. The angle irons 14 are welded at the connection between the sewage pipe 7 and the return pipe 12 and the filter pipe 4 to improve the stability of the connection between the sewage pipe 7 and the return pipe 12 and the filter pipe 4, and to avoid the problem of the sewage pipe 7 and the return pipe 12 being broken by the impact of the water flow.

[0037] The implementation principle of the present application is as follows: when in use, the user first connects the filter tube 4 to the water inlet pipe 2 through the flange 5 and the bolt 6, and then introduces cold water into the filter tube 4. Since the first filter screen 8 is obliquely installed in the filter tube 4, the impurities are filtered. When the impurities are blocked by the filter structure, under the impact of the water flow, the impurities slide along the filter structure into the inner cavity of the sewage storage pipe 7 for storage, and the water flows through the second filter screen 13 and then flows back to the bottom of the filter tube 4 through the return pipe 12, and finally enters the water cooling unit body 1 along the water inlet pipe 2 for refrigeration. When the impurities in the sewage storage pipe 7 are blocked by the filter structure, the impurities slide into the inner cavity of the sewage storage pipe 7 for storage. When there are more impurities, the user can close the ball valve 10 to prevent the clean water and impurities in the filter tube 4 from entering the sewage storage tube 7 temporarily, and then the user opens the sealing component to clean the impurities in the sewage storage tube 7. After cleaning, the user closes the sealing component again and opens the ball valve 10, so that the impurities can be collected through the sewage storage tube 7 again. The use of the water-cooling unit body 1 is not affected when cleaning the impurities, and the need to close the second valve when cleaning the impurities is avoided as much as possible. The user cannot refrigerate normally during the cleaning process, which causes the user to use it very inconveniently.
