[0013] A process of a DTRO high-pressure pump cooling water flushing device: S1: Transport the concentrated copper sulfate solution; the input end of the high-pressure pump sucks the concentrated copper sulfate solution inside the concentrated copper sulfate water tank through the input pipe, and then transports it to the DTRO module through its output end using the output pipe; S2: Treat the concentrated copper sulfate solution; the DTRO module treats the concentrated copper sulfate solution, and the formed fresh water is transported to the fresh water tank through the transport pipe A, the three-way pipe, the connecting pipe A, and the connecting pipe B.

[0014] The advantages of this application are as follows: (1) This application installs and modifies the cooling water flushing pipeline, so that the cooling water flows through the piston surface from left to right during the operation of the high-pressure pump, washing away the highly concentrated copper sulfate solution attached to the ceramic piston surface, thereby alleviating the crystallization phenomenon of the high-pressure pump body.

The adjusting part can change the fulcrum position of the connecting rod B, flexibly adjust the stroke of the stirring blades, adapt to different liquid levels or viscosity requirements, and improve the applicability.

[0016] (3) This application sets up a perturbation component. By using the linkage of the perturbation plate through the guide shaft and the guide groove, it swings left and right as it moves up and down with the connecting rod, specifically agitating the highly concentrated solution at the bottom of the tank, avoiding the accumulation of precipitation, improving the overall mixing effect. Without additional power, it is synchronously driven by the movement of the stirring system, energy-saving and highly reliable. The stirring blades are responsible for mixing the liquid in the middle and upper layers, and the perturbation plate focuses on the bottom layer, forming a three-dimensional stirring network, which is especially suitable for easily crystallized or highly viscous liquids.

[0017] (4) This application sets up a swinging component. The connecting block installed obliquely drives the delivery hose to rotate, which can change the direction of the water flow entering the water inlet nozzle. This design enables the device to flexibly adjust the direction of the water flow during actual use, adapting to different operation requirements. This adjustability is particularly important in applications such as cleaning and spraying, which helps to improve the operation accuracy and effect. Description of the Drawings

[0028] Embodiment 2. Please refer to Figures 1 - 7, on the basis of Embodiment 1, a fixing plate 61 is fixedly connected to the upper end of the copper sulfate concentration water tank 3. An electric motor 62 is fixedly connected to the outer wall of the fixing plate 61. The output end of the electric motor 62 is fixedly connected to a turntable 63. A connecting rod A 64 is hinged to the outer wall of the turntable 63. The other end of the connecting rod A 64 is hinged to a connecting rod B 65. An arc-shaped groove 66 is formed in the outer wall of the connecting rod B 65. A rotating rod 67 is rotatably connected to the outer wall of the fixing plate 61. Two movable plates 68 are fixedly connected to the outer wall of the rotating rod 67. A sliding shaft is fixedly connected between the two movable plates 68. The sliding shaft is slidably connected to the inner wall of the arc-shaped groove 66. A threaded sleeve 69 is fixedly connected to the outer wall of the fixing plate 61. A connecting rod 610 is arranged inside the threaded sleeve 69. A threaded groove 618 is formed in the outer wall of the connecting rod 610. The connecting rod 610 is threadedly connected to the inside of the threaded sleeve 69 through the threaded groove 618. The upper end of the connecting rod 610 is rotatably connected to a connecting shaft 611. A receiving groove 617 is formed inside the connecting shaft 611.

The adjusting shaft 615 is slidably connected to the inside of the adjusting groove 616. A flow regulating valve 18 is arranged inside the connecting pipe A 12. A disturbing assembly 7 is arranged at the bottom of the connecting rod 610.

[0029] During use, first start the motor 62 to drive the turntable 63 to rotate. Then, the connecting rod A64, which is hinged to the outer wall of the turntable 63 at one end, will also rotate accordingly. As a result, the other end of the connecting rod A64 will drive one end of the connecting rod B65, which is hinged to it, to swing within the range of up and down movement. Then, the connecting rod B65 will swing with the sliding shaft between the movable plates 68 as the hinge point. Then, the end of the connecting rod B65 away from the connecting rod A64 will drive the connecting shaft 611 to move up and down reciprocally.

Since the connecting rod 610 is threadedly connected to the inside of the threaded sleeve 69 through the threaded groove 618 opened on its outer side, the connecting rod 610 will rotate during the up and down movement and will rotate in different directions in different up and down movement states. As a result, the stirring blades 619 on the outer wall of the connecting rod 610 will also rotate accordingly, and thus the copper sulfate concentrate liquid in the copper sulfate concentration tank 3 can be stirred. When the capacity of the copper sulfate concentrate liquid in the copper sulfate concentration tank 3 is different, the threaded rod 613 can be rotated.

Then, the adjusting shaft 615 on the side of the moving block 614 will slide inside the adjusting groove 616 on the outer wall of the movable plate 68, and thus the movable plate 68 and the rotating rod 67 can be rotated. Then, the sliding shaft inside the movable plate 68 will slide inside the arc-shaped groove 66, and thus the hinge point of the connecting rod B65 can be adjusted, thereby adjusting the range of up and down movement of the connecting shaft 611.

[0030] Example 3. Please refer to Figures 1 - 7 , on the basis of Example 1, the disturbing assembly 7 includes a fixed block 71.

The guide groove 77 is arranged in an arc shape, and the guide shaft 75 is slidably connected to the inside of the guide groove 77; During use, when the connecting rod 610 moves up and down, the rectangular frame 76 at its bottom will also move up and down accordingly. Then, the height of the guide groove 77 opened on the outer wall of the rectangular frame 76 will also change accordingly. Then, the guide shaft 75 slidably connected to the inside of the guide groove 77 will slide inside it. Then, the guide shaft 75 will drive the rotating shaft 72 to swing left and right through the rotating block 74. Then, the disturbing plate 73 at the other end of the rotating shaft 72 will also swing left and right accordingly, and thus the copper sulfate concentrate liquid at the bottom of the copper sulfate concentration tank 3 can be disturbed, preventing the copper sulfate concentrate liquid at the bottom from always staying at the bottom and being difficult to be stirred.

[0031] Example 4. Please refer to Figures 1 - 7, on the basis of Embodiment 1; a swing assembly 8 is assembled on the outer wall of the high-pressure pump 1.

[0032] During use, when the high-pressure pump 1 is started, its output end will drive the pulley A 81 to rotate. Then, under the driving action of the transmission belt 82, the pulley B 83 will be driven to rotate. Then, the pulley B 83 will drive the mounting shaft 85 to rotate. Then, the connecting block 86 on the outer wall of the mounting shaft 85 can be driven to rotate. Then, the connecting block 86 can drive the delivery hose 13 to rotate. Since the connecting block 86 is obliquely mounted with respect to the mounting shaft 85, when the connecting block 86 drives the delivery hose 13 to rotate, the water flow direction of the delivery hose 13 entering the inside of the water inlet nozzle 16 can also be changed.

Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.

8. A DTRO high-pressure pump cooling water flushing device according to claim 7, characterized in that, The connecting block (86) is inclined and installed on the outer wall of the mounting shaft (85).

9. The process of a DTRO high-pressure pump cooling water flushing device according to any one of claims 1-8, characterized in that: It includes the following steps: S1: Transport copper sulfate concentrated water; the input end of the high-pressure pump (1) sucks the copper sulfate concentrated water inside the copper sulfate concentration water tank (3) through the input pipe (2), and then transports it to the DTRO module (5) through its output end using the output pipe (4); S2: Treat copper sulfate concentrated water; the DTRO module (5) treats the copper sulfate concentrated water. The formed fresh water is transported to the fresh water tank (15) through the transport pipe A (9), the three-way pipe (11), the connecting pipe A (12) and the connecting pipe B (14). The untreated concentrated water returns to the copper sulfate concentration water tank (3) through the transport pipe B (10); S3: Flush the pipeline; by means of the flow regulating valve (18), part of the fresh water is transported to the water inlet nozzle (16) through the three-way pipe (11) and the delivery hose (13), so that the cooling water flows through the piston surface from left to right during the operation of the pump, washing away the high-concentration copper sulfate solution attached to the ceramic piston surface, and then transporting the fresh water to the inside of the fresh water tank (15) through the water outlet nozzle (17) and the connecting pipe B (14).
