[0027] The present invention will be further described below with reference to the accompanying drawings and implementation examples.

[0028] First embodiment

[0029] Please refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 ,in, Figure 1 This is a structural schematic diagram of a first embodiment of a cooling device for injection water use point provided by the utility model; Figure 2 for Figure 1 The schematic diagram of the partial cross-sectional structure of the shell shown; Figure 3 for Figure 2 Schematic diagram of the cooling pipe structure shown; Figure 4 for Figure 2 The schematic diagram of the scraper structure from above is shown. A cooling device for use at a point of use of water for injection comprises: a mounting plate 1;

[0030] The housing 2 is fixedly mounted on the front of the mounting plate 1 , with an output pipe 22 fixedly mounted on the top of one side of the housing 2 and an input pipe 21 fixedly mounted on the bottom of the other side of the housing 2 ;

[0031] A cooling pipe 3 is provided on the inner side of the housing 2;

[0032] A drive motor 5 is fixedly mounted on the top of the housing 2. A reciprocating screw 51 is fixedly mounted on the output end of the drive motor 5. A threaded ring 52 is threadedly connected to the outer side of the reciprocating screw 51. A scraper 53 is fixedly mounted on the outer side of the threaded ring 52. A plurality of cleaning holes 54 are formed inside the scraper 53. A through groove 55 is also formed inside the scraper 53.

[0033] The material collecting frame 4 is fixedly installed on the bottom of the shell 2 . A first discharge valve 41 is fixedly installed on the bottom of the material collecting frame 4 . A material storage pipe 42 is threadedly connected to the bottom of the first discharge valve 41 .

[0034] The output end and the output end of the cooling pipe 3 are respectively arranged at the bottom and the top of the shell 2.

[0035] When in use, the injection water that needs to be cooled can be transported from the bottom of the shell 2 to the inner side of the shell 2 and then output through the top of the shell 2 .

[0036] The outer side surface of the scraper 53 is in contact with the inner side surface of the housing 2 , and the inner sides of the cleaning holes 54 are in contact with the outer side surface of the cooling pipe 3 .

[0037] The outer side surface of the scraper 53 is attached to the inner side surface of the shell 2 , and when in use, it can clean impurities and scale adhered to the inner wall of the shell 2 .

[0038] The bottom of the inner side surface of the shell 2 is inclined, and the end close to the collecting frame 4 is lower.

[0039] Because the bottom of the inner side of the shell 2 is inclined, the cleaned impurities can slide to the inner side of the aggregate frame 4, so that the staff can collect and process them later; and a first discharge valve 41 is installed at the bottom of the aggregate frame 4, so that when the impurities on the inner side of the storage pipe 42 are cleaned, the first discharge valve 41 can be closed to prevent the cooling water from flowing out.

[0040] The working principle of the cooling device for injection water use point provided by the utility model is as follows:

[0041] When in use, the injection water inside the injection water network pipe enters the interior of the cooling pipe 3 through the input end of the cooling pipe 3, and then the external cooling water is transported to the inner side of the shell 2 through the input pipe 21. Thereafter, the cooling water flows on the outer side of the cooling pipe 3, thereby cooling the injection water inside the cooling pipe 3. The cooled injection water is discharged through the output end of the cooling pipe 3, and the cooling water after use is discharged through the output pipe 22.

[0042] When, after long-term use, a large amount of impurities and scale accumulate on the outer side of the cooling tube 3, affecting the heat exchange effect, the user can start the drive motor 5, so that the drive motor 5 drives the reciprocating screw 51 to be threadedly connected to the inner side of the thread ring 52, so that the thread ring 52 drives the scraper 53 to move up and down on the inner side of the shell 2. At this time, the inner side of the cleaning hole 54 is in contact with the outer side of the cooling tube 3, so that the impurities and scale accumulated on the outer side of the cooling tube 3 can be cleaned.

[0043] Compared with related technologies, the cooling device for injection water use point provided by the present invention has the following beneficial effects:

[0044] The driving motor 5 drives the screw rod 51 to be threadedly connected to the inner side of the thread ring 52, and then the thread ring 52 drives the cleaning hole 54 opened on the scraper 53 to move up and down on the outer side of the cooling pipe 3, so as to clean the impurities and scale accumulated on the outer side of the cooling pipe 3 and increase the heat exchange effect of the cooling water between the cooling pipe 3 and the inner side of the shell 2.

[0045] Second embodiment

[0046] Please refer to Figure 5 Based on the cooling device for injection water point-of-use provided in the first embodiment of this application, the second embodiment of this application provides another cooling device for injection water point-of-use. The second embodiment is merely a preferred embodiment of the first embodiment, and implementation of the second embodiment will not affect the independent implementation of the first embodiment.

[0047] Specifically, the second embodiment of the present application provides a cooling device for a point-of-use of water for injection. The difference is that, in a cooling device for a point-of-use of water for injection, one end of the output pipe 22 is fixedly mounted with a mounting seat 6, the bottom of the mounting seat 6 is fixedly mounted with a vertical pipe 61, and the bottom of one side of the vertical pipe 61 is fixedly mounted with a liquid outlet pipe 65.

[0048] A through hole 62 is provided at the bottom of the mounting seat 6 , a sealing cover 63 is threadedly connected to the bottom of the outer side of the vertical pipe 61 , a filter frame 64 is fixedly mounted on the top of the sealing cover 63 , and the top of the filter frame 64 abuts against the bottom of the mounting seat 6 .

[0049] A second discharge valve 66 is fixedly mounted on the bottom of the sealing cover 63 .

[0050] When the filter frame 64 needs to be maintained, the user can remove the sealing cover 63 from the bottom thread connection of the outer side of the vertical pipe 61 to disassemble the sealing cover 63 and the filter frame 64.

[0051] The working principle of the cooling device for injection water use point provided by the utility model is as follows:

[0052] When in use, the cooling water output from the inner side of the housing 2 enters the inner side of the mounting base 6 through the output pipe 22, and then enters the inner side of the filter frame 64 through the through hole 62 opened at the bottom of the mounting base 6. After that, it is filtered by the filter frame 64 and the liquid is discharged through the liquid outlet pipe 65.

[0053] When the impurities on the inner side of the filter frame 64 need to be cleaned after long-term use, the user can open the second discharge valve 66 to discharge the impurities accumulated on the inner side of the filter frame 64 .

[0054] Compared with related technologies, the cooling device for injection water use point provided by the present invention has the following beneficial effects:

[0055] By cooperating with each other through the structures such as the mounting seat 6, the vertical pipe 61, the through hole 62, the sealing cover 63, the filter frame 64, the liquid outlet pipe 65 and the second discharge valve 66, when in use, the cooling water discharged from the inside of the shell 2 enters the inner side of the filter frame 64, and is then filtered and discharged through the filter frame 64. In this way, the discharged impurities can be collected, which is convenient for the user to handle later.

[0056] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the description and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
