DETAILED DESCRIPTION

[0018] The specific implementation of the present invention is further described below in conjunction with the accompanying drawings and embodiments. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and cannot be used to limit the protection scope of the present invention.

[0019] The “top surface”, “bottom surface” and “bottom surface” are based on the normal use state of the inclined tube sedimentation tank and are only for the convenience of describing the present invention and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they cannot be understood as limitations on the present invention.

[0020] like Figure 1 and 2 As shown, an inclined tube sedimentation tank for purifying electroplating wastewater includes a tank body 1 with an open top; a mud discharge pipe 2, which is arranged at the bottom of the tank body 1; a plurality of inclined tubes 3, each of which is distributed in an array inside the tank body 1; a hoisting mechanism 4, which is erected just above the tank body 1, along the length direction of the tank body 1 as a first direction, and the hoisting mechanism 4 is slidably connected to the tank body 1 along the first direction; a plurality of cleaning mechanisms 5, each of which is arranged on the hoisting mechanism 4 at equal intervals perpendicular to the first direction; the hoisting mechanism 4 controls each of the cleaning mechanisms 5 to move and rise and fall along the first direction, so that the cleaning mechanisms 5 extend into different inclined tubes 3 and clean the inclined tubes 3.

[0021] The above-mentioned inclined tube sedimentation tank can precipitate the sediment in the electroplating wastewater to achieve the purification of the electroplating wastewater; when in use, after the wastewater enters the tank body 1, it passes through the inclined tubes 3 arranged obliquely from bottom to top. During this process, the sediment in the wastewater is precipitated to complete the purification of the wastewater. During this process, sludge will accumulate on the inner wall of the inclined tube, causing the inclined tube to be blocked; the number of cleaning mechanisms 5 arranged on the winch mechanism 4 is consistent with the number of inclined tubes 3 in the same column and corresponds one to one. The winch mechanism 4 drives each cleaning mechanism 5 to move along the first direction so that the cleaning mechanism 5 can be aligned with each inclined tube 3 in different columns. After the alignment is completed, the winch mechanism 4 controls the lifting and lowering of the cleaning mechanism 5, so that the cleaning mechanism extends into the interior of the inclined tube 3 to clean the inclined tube, thereby keeping the interior of the inclined tube 3 clean and the inclined tube unobstructed, thereby improving the sedimentation efficiency of the inclined tube sedimentation tank, and then improving the purification effect of the inclined tube sedimentation tank on electroplating wastewater.

[0022] A further improvement is, Figure 1 and 2 As shown, the tank body 1 includes a sedimentation tank 103, a sewage tank 101 and a clean water tank 104. The top of the sedimentation tank 103 is open, and the bottom of the sedimentation tank 103 is connected to the bottom of the sewage tank 101. The sedimentation tank 103 and the clean water tank 104 are separated from each other by an overflow plate 113. The mud discharge pipe 2 is arranged at the bottom of the sedimentation tank 103, and an extrusion piece for extruding sludge is arranged inside the mud discharge pipe 2.

[0023] Specifically, the sewage tank 101 is connected to the water inlet pipe 102, and the clean water tank 104 is connected to the drain pipe; the sewage enters the sewage tank 101 through the water inlet pipe 102, and then enters the sedimentation tank 103 from the bottom of the sewage tank 101, and then the sewage flows upward from the bottom of the sedimentation tank 103 through each inclined tube 3. In this process, the sediment in the sewage is precipitated to achieve sewage purification. The purified water overflows the overflow plate 113 and enters the clean water tank 104, and then is discharged through the drain pipe 105 to complete the sewage purification; the extrusion component includes a worm 201 coaxially arranged inside the mud discharge pipe 2 and a first motor 202 fixedly connected to the mud discharge pipe 2. The precipitated sludge enters the mud discharge pipe 2 at the bottom of the sedimentation tank 103, and the worm 201 is driven by the first motor 202 to rotate, so that the sludge inside the mud discharge pipe 2 is squeezed out from one end thereof through the worm 201 to complete the cleaning of the sludge.

[0024] A further improvement is, Figure 7As shown, the hoisting mechanism 4 includes a moving beam 402 which is slidably connected to the pool body 1, the pool body 1 is provided with a translational power member for driving the moving beam 402 to move, a rotating shaft 403 is provided on the moving beam 402 for horizontal rotation perpendicular to the first direction, the moving beam 402 is provided with a rotating power member for driving the rotating shaft 403 to rotate, the cleaning mechanism 5 includes a flexible cable 405, the cable 405 is wound on the outer periphery of the rotating shaft 403, and the moving beam 402 is provided with a guide hole 406 for passing the cable 405.

[0025] Specifically, the translation force member includes an outer guide rail 110 fixed on both sides of the pool body along the first direction, a moving trolley 401 that can reciprocate along the outer guide rail 110 is installed on the outer guide rail 110, and a moving beam 402 is horizontally erected between the two moving trolleys 401, and the moving trolley drives the moving beam 402 to move along the first direction, so that each cleaning mechanism 5 can be aligned with each inclined tube 3 in different rows; the rotating shaft 403 is connected to the moving beam 402 through a bearing, and a second motor 404 is fixedly connected to the moving beam 402, and the rotating shaft 403 is driven by the second motor 404 to rotate forward and reverse. When the rotating shaft 403 rotates forward, The cable 405 is wound on the outer circumference of the rotating shaft 403, so that the cleaning mechanism 5 is pulled up by the cable 405. When the rotating shaft 403 rotates in the opposite direction, the cable 405 is lowered from the rotating shaft 403, so that the cleaning mechanism 5 moves downward under the action of its own gravity, thereby realizing the lifting and lowering of the cleaning mechanism 5, so that the cleaning mechanism 5 can move along the inclined tube 3, and then realize the cleaning of the inside of the inclined tube 3; the lifting and lowering of the cleaning mechanism 5 is controlled by the pulling force of the flexible cable 405 and the gravity of the cleaning mechanism 5 itself, so that the cleaning mechanism 5 can move inside the inclined tube 3 with different inclination angles, thereby completing the cleaning of the inclined tube 3.

[0026] A further improvement is, Figure 8-10 As shown, the cleaning mechanism 5 includes a mounting shaft 505 , a threading hole 506 is provided at the top of the mounting shaft 505 , a gravity block 501 is fixedly connected to the bottom end of the mounting shaft 505 , and a scraping assembly 502 is detachably connected to the mounting shaft 505 .

[0027] Specifically, the threading hole 506 is used to connect the end of the cable 405, which is convenient for connecting and separating the installation shaft 505 and the cable 405. The gravity block 501 is used to provide sufficient gravity so that the cleaning mechanism 5 can overcome the resistance between itself and the inner wall of the inclined tube 3 and move downward along the inclined tube 3. The gravity block 501 arranged at the bottom end of the installation shaft 505 can also keep the installation shaft 505 in a vertical state, which is convenient for docking with the inclined tube 3. During the movement of the cleaning mechanism 5, the sludge on the inclined tube 3 is scraped downward by the scraping assembly 502, thereby completing the cleaning of the inclined tube 3; a threaded section 507 is also provided at the top of the installation shaft 505, and a nut 508 is threadedly connected to the threaded section 507. The scraping assembly 502 can be reinforced by the setting of the nut 508, and the firmness of the connection between the scraping assembly 502 and the installation shaft 505 can be improved. At the same time, the scraping assembly 502 and the installation shaft 505 can be disassembled and assembled by disassembling and assembling the nut 508, thereby improving the convenience of equipment maintenance.

[0028] A further improvement is, Fig.10 As shown, the scraper assembly 502 includes a support frame 5022, which has an inner ring and an outer ring fixedly connected to each other. The inner ring is sleeved on the outer circumference of the mounting shaft 505, a filter screen 5023 is arranged between the inner ring and the outer ring, and an annular scraper strip 5021 is fixedly connected to the outer circumference of the outer ring.

[0029] Specifically, the support frame 5022 is used to support and reinforce the filter screen 5023 and the scraper strip 5021. The scraper strip 5021 is a rubber strip, which has good elasticity and can fit tightly with the inner wall of the inclined tube 3. When the cleaning mechanism 5 moves downward along the inclined tube 3, the sludge adhering to the inclined tube 3 is scraped off by the scraper strip 5021; when the cleaning mechanism 5 descends, the water flows through the inclined tube 3 from bottom to top, and the filter screen 5023 is set to allow the water to pass through, thereby reducing the resistance of the water flow to the cleaning mechanism 5 and improving the smoothness of the movement of the cleaning mechanism 5 along the inclined tube. At the same time, the filter screen 5023 can also filter the sludge in the water flow to prevent the scraped sludge from flowing upward along the water flow and finally entering the clean water tank 104, thereby reducing the impact on the purification effect of the inclined tube sedimentation tank when cleaning the inclined tube 3.

[0030] A further improvement is, Fig.11 As shown, a cleaning component 503 is detachably connected to the mounting shaft 505, and scraping components 502 are provided on both sides of the cleaning component 503 along the axial direction of the mounting shaft 505. The cleaning component 503 includes a rotating sleeve 5031 coaxially sleeved on the outer periphery of the mounting shaft 505, and bristles 5032 are evenly distributed on the outer peripheral surface of the rotating sleeve 5031. The outer periphery of the rotating sleeve 5031 is circumferentially provided with paddles 5033 for driving the rotating sleeve 5031 to rotate.

[0031] Specifically, the rotating sleeve 5031 is connected to the installation shaft 505 through a bearing, so that the rotating sleeve 5031 can rotate smoothly, and the two cleaning components 503 arranged at intervals abut against the inner wall of the inclined tube 3, which can play a role in positioning the installation shaft 505, so that the installation shaft 505 can remain coaxial with the inclined tube 3 during the movement along the inclined tube 3; when the above-mentioned cleaning mechanism 5 is in use, the inner wall of the inclined tube 3 is first cleaned by the scraping strip 5021 located below; when the cleaning mechanism 5 descends, it moves relative to the water flow, and the water flow impacts the paddle 5033, so that the paddle 5033 drives the rotating sleeve 5031 to rotate, thereby driving the bristles 5032 to rotate to clean the inner wall of the inclined tube 3 for the second time, and finally The inner wall of the inclined tube is cleaned for the third time by the scraper strip 5021 located at the top, thereby improving the cleaning effect of the inner wall of the inclined tube 3; the bristles 5032 can be polytetrafluoroethylene bristles, which can improve the corrosion resistance of the bristles 5032 and reduce the friction between the bristles 5032 and the inner wall of the inclined tube 3, thereby improving the cleaning effect and reducing the resistance of the cleaning mechanism 5 to descend, and also reducing the adhesion of sludge on the bristles 5032, thereby extending the service life of the bristles 5032; filter screens 5023 are provided on the front and rear sides of the bristles 5032, and the sludge cleaned by the bristles 5032 can be filtered out by the filter screen 5023, thereby preventing the sludge from flowing upward along the water flow to the inside of the clean water tank 104, so as to ensure the water purification effect of the inclined tube sedimentation tank.

[0032] In the above-mentioned inclined tube sedimentation tank, when the cleaning mechanism 5 descends, the driving force is mainly provided by its own gravity, and when it rises, it is powered by the cable 405. In addition, during its ascent, the water flow from bottom to top along the inclined tube 3 can also provide assistance to the cleaning mechanism 5, thereby reducing the energy consumption when the winch mechanism 4 drives the cleaning mechanism 5 to rise and fall, and improving the energy-saving effect of the inclined tube sedimentation tank.

[0033] A further improvement is, Fig.11 As shown, an eccentric block 5034 is fixedly connected to one side of the rotating sleeve 5031. The setting of the eccentric block 5034 can make the rotating sleeve 5031 vibrate during the rotation process, thereby driving the cleaning mechanism 5 to vibrate, and the sludge adhering to the inner wall of the inclined tube 3 can be loosened by the vibration, further improving the cleaning effect of the inclined tube 3.

[0034] A further improvement is, Fig. 9 As shown, the gravity block 501 is a conical structure coaxially arranged with the installation shaft 505, and a plurality of notches 504 are evenly spaced around the axis of the gravity block 501. The conical gravity block 501 can play a guiding role when the cleaning mechanism 5 is docked with the top opening of the inclined tube 3, thereby improving the convenience and accuracy of aligning the cleaning mechanism 5 with the inclined tube 3.

[0035] A further improvement is, Figure 3-6As shown, a bottom plate 107 is horizontally arranged at the bottom of the sedimentation tank 103, and plug holes 111 are arranged in an array on the bottom plate 107. The connection between the sedimentation tank 103 and the sewage tank 101 is located below the bottom plate 107. A movable plate 108 is horizontally arranged above the bottom plate 107 along a first direction, and positioning holes 112 are arranged in an array on the movable plate 108. The number of the plug holes 111 and the positioning holes 112 is consistent with the number of the inclined tube 3 and corresponds one to one. The inner diameters of 111 and the positioning hole 112 are both larger than the outer diameter of the inclined tube 3. The inclined tube 3 passes through the plug hole 111 and the positioning hole 112 in sequence, and the inclined tube 3 is sealed and connected to the plug hole 111; the inner walls on both sides opposite to the sedimentation tank 103 are fixedly connected with inner guide rails 109 along the first direction, and the movable plate 108 is mounted above the two inner guide rails 109. The sedimentation tank 103 is fixedly connected with a transverse driving force member, and the movable end of the transverse driving force member is fixedly connected to the movable plate 108.

[0036] Specifically, the lateral driving force member is a hydraulic cylinder 106, and the moving end of the hydraulic cylinder 106 is fixedly connected to the moving plate 108 by bolts. A rubber sealing ring 301 is sleeved on the outer periphery of the inclined tube 3, and the inclined tube 3 is sealed and connected to the plug hole 111 through the sealing ring 301. In this way, the upper and lower parts of the sedimentation tank 103 can be separated by the bottom plate 107 to prevent the sediment deposited at the bottom of the sedimentation tank 103 from spreading upward; when in use, the hydraulic cylinder 106 pushes the moving plate 108 to move in the first direction, thereby driving the top end of the inclined tube 3 to move through the moving plate 108 to adjust the inclination angle and inclination direction of the inclined tube 3. The inclined tube 3 is elastically connected to the bottom plate 107 through the sealing ring 301 to facilitate the angle adjustment of the inclined tube 3; when the inclined tube is adjusted to the horizontal direction, the inclined tube When the inclined tube 3 is rotated in the vertical direction, the inclined tube 3 has a smaller inclination angle, and the sludge accumulated in the inclined tube 3 is more likely to slide down from the inclined tube 3. By reciprocating the inclined tube between the inclined and vertical states, the sludge accumulation in the inclined tube 3 can be reduced while improving the sewage purification effect of the inclined tube 3, so that the inclined tube 3 can be kept clean and the sewage purification effect of the inclined tube sedimentation tank can be improved. When the cleaning mechanism 5 is used to clean the sludge in the inclined tube 3, the inclined tube 3 can be turned to the vertical state, so as to reduce the resistance of the cleaning mechanism 5 to move in the inclined tube 3 and improve the cleaning effect of the cleaning mechanism 5 on the inclined tube.

[0037] In the inclined tube sedimentation tank, the inclined tube 3 is a round tube, which can make the inner wall of the inclined tube 3 smoother and facilitate cleaning by the cleaning mechanism 5. The movable plate 108 is placed above the inner hole 109, and the movable plate 108 can be conveniently taken in and out from the top; each inclined tube 3 is independently plugged into the plug hole 111 and the positioning hole 112, and the inclined tube 3 can be directly pulled out upward, which is convenient for disassembly and assembly of the inclined tube 3. When the inclined tube 3 is blocked and difficult to clean, the blocked inclined tube 3 can be taken out separately for flushing, which greatly improves the convenience of maintenance of the inclined tube sedimentation tank.
