DETAILED DESCRIPTION

[0029] A preferred embodiment of the present invention is described in detail below with reference to the accompanying drawings.

[0030] To achieve the above purpose, the embodiment of the present invention adopts the following technical solution: Figure 1, a circulation cleaning system for a water cooling system of a ship, comprising a plate heat exchanger 10, a cleaning device, a water tank 20, and a mixing box 40, wherein the cleaning device is arranged at the periphery of the plate heat exchanger 10 and is used to flush the scale on the wall of the plate heat exchanger, the water inlet of the water tank is connected to the water outlet of the plate heat exchanger, the water outlet of the water tank is connected to the water inlet of the plate heat exchanger through a circulating pump 30, the mixing box is arranged on the inner wall of the water tank, a stirring mechanism is arranged inside the mixing box, a collecting bin 430 is arranged on the side wall of the mixing box and is connected to the overflow port 420 at the top of the mixing box, the collecting bin is provided with a multi-stage filtering part, an extruding part and a conveying part from top to bottom, and a material discharge part is provided on the bottom wall of the mixing box, it should be noted that the cleaning device in this embodiment is a high-frequency spiral pulse pipeline cleaning all-in-one machine, when in use, the cleaning device, the plate heat exchanger and the water tank are connected with a hose and a joint, the cleaning liquid is added, the cleaning device is started, and the water temperature is heated, and the high-frequency, deep spiral shock wave is used to impact the pipe The scale is washed out of the wall, and the scale enters the water tank, and is filtered and then circulated for cleaning to achieve an ideal cleaning effect; in addition, since the plate heat exchanger will not only produce scale during operation, but also have other impurities after long-term use, such as silt, rust, algae, suspended matter and other particulate impurities, when the scale and the water mixed with the above impurities are mixed and enter the water tank, they will first enter the mixing box. At this time, flocculant can be added to the mixing box, and the stirring action of the stirring mechanism can be combined to facilitate the sedimentation of scale and impurities, and the suspended impurities floating on the water surface of the mixing box can enter the collecting bin through the overflow port, and after multi-stage filtration of the multi-stage filtration part in the collecting bin, and extrusion of the extrusion part, the impurities are output to the collecting bin through the conveying part. At the same time, the impurities settled in the mixing box can be output from the mixing box through the unloading part. Therefore, the present invention can realize the cleaning of the ship water cooling system pipeline including scale, and effectively treat the impurities after cleaning, and can achieve the descaling effect without dismantling the water cooling equipment.

[0031] Reference Figure 2 , Figure 3 As a preferred technical solution of this embodiment, the stirring mechanism includes a driving motor 411, a worm 412, a worm wheel 413 and a stirring assembly. The driving motor 411 is arranged on the side wall of the mixing box 40, the worm 412 is arranged at the output end of the driving motor, the worm wheel 413 is rotatably arranged on the side wall of the mixing box, and the worm wheel and the worm are meshed. The stirring assembly is placed inside the mixing box, and the stirring assembly is connected to the worm wheel shaft and is driven to rotate by the worm wheel. When in use, the driving motor drives the worm to rotate, and the worm drives the worm wheel to rotate, and the worm wheel drives the stirring assembly inside the mixing box to rotate, so as to stir the water in the mixing box, so as to facilitate the flocculant added to the mixing box to fully react with the impurities in the water.

[0032] Furthermore, the stirring assembly includes a main shaft 414, a cross bar 415 and a secondary shaft 416. The main shaft 414 is connected to the worm gear shaft. There are multiple cross bars 415, and the multiple cross bars are arranged perpendicular to the axial direction of the main shaft. The secondary shaft 416 is arranged parallel to the axial direction of the main shaft, and the secondary shaft is arranged between the cross bars. It should be noted that the number of secondary shafts can also be set to multiple. In this way, the main shaft, cross bars and secondary shafts can form a frame structure, and the frame structure can rotate when driven by the worm gear shaft to stir the water in the mixing box.

[0033] Furthermore, when the flocculant reacts with the water in the mixing box, suspended impurities will float on the surface of the water, such as algae, light scaling, etc. In order to facilitate the cleaning of such impurities, a tossing brush 480 is rotatably connected to the overflow port of the mixing box 40. At the same time, in order to drive the tossing brush, the shaft of the worm gear 413 is also provided with a first transfer wheel 417. Correspondingly, the shaft of the tossing brush is fixedly provided with a second transfer wheel 418, and a first transfer belt 419 is provided between the first transfer wheel and the second transfer wheel. When in use, when the driving motor drives the worm gear to rotate through the worm, it will synchronously drive the first transfer wheel to rotate. The first transfer wheel then drives the second transfer wheel to rotate through the first transfer belt, thereby driving the tossing brush to rotate. When the tossing brush rotates, it stirs the overflow port of the mixing box, thereby tossing the suspended matter on the upper surface of the water to the discharge overflow port, and finally enters the collection bin to wait for further processing.

[0034] Reference Figure 4 , Figure 5 As a preferred technical solution of this embodiment, the multi-stage filtration unit includes a filter box, a first filter plate 442 and a second filter plate 443. The filter box is arranged inside the collection bin 430, the first filter plate 442 is rotatably arranged on the inner wall of the collection bin 430, and the end of the first filter plate away from the collection bin extends toward the filter box, the second filter plate 443 is rotatably arranged at the bottom of the filter box, and the end of the second filter plate away from the filter box extends toward the end of the first filter plate. When in use, the surface water moved by the moving brush is mixed with suspended matter and falls to the top of the filter box. After being filtered by the filter box, it enters the second filter plate and the first filter plate in turn. In this way, after multi-stage filtration by the filter box, the second filter plate and the first filter plate, the separation of water and impurities is achieved, and then the filtered impurities are extruded and formed by the extrusion unit.

[0035] It should be noted that both the first filter plate and the second filter plate are provided with filter holes, which are used to separate water and impurities. At the same time, since the first filter plate is rotatably arranged on the inner wall of the collection bin, when the gravity of the impurities falling on the first filter plate drives the first filter plate to rotate, the impurities filtered on the first filter plate can be discharged to the extrusion part for extrusion molding. In addition, in order to facilitate the rotation and resetting of the first filter plate after rotation, a torsion spring is also provided on the rotating shaft connecting the first filter plate and the collection bin.

[0036] Reference Figure 6 Furthermore, the filter box includes an inclined section 4411, a vertical section 4412 and a horizontal section 4413. The inclined section 4411 extends downward from the inner wall of one side of the collecting bin 430, the vertical section 4412 is arranged at the bottom of the inclined section, and the horizontal section 4413 extends from the vertical section to the inner wall of one side of the collecting bin. At the same time, a gap is provided between the vertical section and the inner wall of the other side of the collecting bin, and filtering mesh holes are provided on the inclined section and the horizontal section. When in use, water mixed with impurities first falls to the inclined section, and then falls onto the first filter plate through the gap after being filtered by the inclined section.

[0037] As a preferred technical solution of this embodiment, the extrusion part includes a limit plate 451, an extrusion motor 452, a bidirectional lead screw 453 and an extrusion block 454. The limit plate 451 is fixedly mounted on the inner wall of the collecting bin 430, and a filter mesh is also provided on the extrusion plate. The extrusion motor 452 is arranged on the side wall of the collecting bin, the bidirectional lead screw 453 is arranged at the output end of the extrusion motor, and the bidirectional lead screw is extended along the inner cavity of the collecting bin. There are two extrusion blocks 454, and the two extrusion blocks are respectively arranged on the threaded section of the bidirectional lead screw. When in use, the extrusion block is slidably arranged in the cavity formed by the inner walls on both sides of the collecting bin and the limit plate 451. Specifically, when the extrusion motor is working, it drives the bidirectional lead screw to rotate on the side wall of the collecting bin. When the bidirectional lead screw rotates, it can drive the two extrusion blocks thereon to approach or move away from each other, and extrude the impurities dropped onto the extrusion plate when the two extrusion blocks approach each other. It should be noted that since the extrusion block is clamped on the inner wall of the collecting bin, the extrusion block can be driven by the bidirectional lead screw to achieve axial linear displacement along the bidirectional lead screw.

[0038] Furthermore, the conveying part includes a conveying plate 461, a discharging cylinder 462, a discharging plate 463 and a conveying belt 464. The conveying plate 461 is arranged on the inner wall of the collecting bin 430 below the limiting plate 451. The discharging cylinder 462 is fixed to the inner wall of the collecting bin, and the piston rod at the output end of the discharging cylinder passes through the conveying plate. The discharging plate 463 is arranged at the output end of the discharging cylinder, and the discharging plate and the limiting plate are movably opposed. The conveying belt 464 is symmetrically arranged on the inner side of the conveying plate. At the same time, the top surface of the conveying belt is higher than the top surface of the conveying plate. Discharge ports are provided at both ends of the plate. When the impurities on the limit plate are squeezed by the extrusion part, the discharge cylinder pushes the discharge plate and the limit plate to resist each other, so that the limit plate forms a complete plate structure. After the extrusion is completed, the discharge cylinder can drive the discharge plate to move downward to move the extruded impurities to the conveying plate through the discharge plate. Since the top surface of the conveying belt is higher than the top surface of the conveying plate, when the discharge plate drives the extruded impurities to discharge, the impurities will be placed on the conveying belt, and the conveying belt will be used to transport the impurities to the discharge port, and finally output to the collection bin.

[0039] Furthermore, the unloading part includes a screw 471, a unloading block 472, a unloading plate 473 and a unloading cylinder 474. The screw 471 is rotatably arranged in the bottom inner cavity of the mixing box 40, the unloading block 472 is threadedly arranged on the screw, and the unloading block can move along the bottom wall of the mixing box, and the unloading plate 473 is movably arranged at the unloading port at the bottom of the mixing box. The unloading cylinder 474 is used to drive the unloading plate to move relative to the unloading port. The unloading cylinder is used to realize the opening and closing of the unloading plate. When in use, the screw will drive the unloading block to move along the axial direction of the screw when it rotates, so as to scrape the impurities settled at the bottom of the mixing box. When the unloading block moves to the unloading port position, the unloading plate can be pushed to open by the unloading cylinder to discharge the scraped impurities out of the mixing box through the unloading port. It should be noted that the bottom cross-section of the mixing box is trapezoidal, and the unloading block can be clamped at the bottom of the mixing box, so that the linear movement of the unloading block can be realized under the drive of the screw.

[0040] Furthermore, in order to realize the driving of the lead screw, a transmission component is provided between the lead screw 471 and the bidirectional lead screw 453, and the transmission component includes a third transmission wheel 475 fixed on the wall of the bidirectional lead screw shaft, a fourth transmission wheel 476 fixed on the side of the lead screw shaft, and a second transmission belt 477 arranged between the third transmission wheel and the fourth transmission wheel. When in use, when the bidirectional lead screw rotates, it can further drive the third transmission wheel to rotate, and the third transmission wheel further drives the fourth transmission wheel to rotate through the second transmission belt, and the fourth transmission wheel further drives the lead screw to rotate. In this way, the bidirectional lead screw and the lead screw can realize synchronous rotation, so as to realize the synchronous extrusion of impurities in the collection bin and the discharge of impurities in the mixing box.

[0041] When in use, the cleaning equipment, plate heat exchanger and water tank are connected with hoses and joints, cleaning liquid is added, the cleaning equipment is started, and the water temperature is heated. The high-frequency, deep spiral shock wave is used to impact the tube wall to flush out the scaling, and the scaling enters the water tank. After filtering, the cyclic cleaning achieves the ideal cleaning effect. In addition, since the plate heat exchanger will not only produce scaling during operation, but also other impurities such as sediment, rust, algae, suspended matter and other particulate impurities after long-term use, when the scaling and the water mixed with the above impurities are mixed and enter the water tank, they will first enter the mixing tank. At this time, flocculants can be added to the mixing tank, and the stirring action of the stirring mechanism can be combined to facilitate the sedimentation of scaling and impurities. The suspended impurities floating on the water surface of the mixing tank can enter the collection bin through the overflow port. After multi-stage filtration in the collection bin and extrusion by the extrusion part, they are output to the collection bin through the conveying part. At the same time, the impurities settled in the mixing tank can be output from the mixing tank through the unloading part.
