[0036] The specific embodiments of the present utility model will be described in detail below in conjunction with the accompanying drawings.

[0037] As Figures 1 - 3 As shown together, the scale removal device for coagulation tanks proposed in this embodiment can be used for scale removal work in the coagulation tanks and flocculation tanks of the zero-discharge process complete equipment for wastewater treatment, and can also be used for scale removal of other tank bodies.

[0038] The coagulation tank and the flocculation tank have different functions in sewage treatment. The coagulation tank is at the front end of treatment, adding a coagulant to make suspended solids aggregate into large particles, and is suitable for high-concentration sewage; while the flocculation tank, after coagulation, adds a flocculant to make the particles aggregate into flocs to improve the sedimentation effect. The tank body structures of the coagulation tank and the flocculation tank are similar, and the scale removal device for the coagulation tank can be used for scale removal.

[0039] The scale removal device for the coagulation tank includes a traveling mechanism 1, a connecting mechanism 2, and a scale removal mechanism 3 arranged from top to bottom. The traveling mechanism 1 is used for the entire scale removal device for the coagulation tank to automatically move outside the tank. The connecting mechanism 2 is used to connect the traveling mechanism 1 and the scale removal mechanism 3, so that the scale removal mechanism 3 can reach any position on the inner wall of the tank. The scale removal mechanism 3 can enter the liquid and is used to automatically scrape off the dirt on the tank wall.

[0040] Specifically, in order to stably travel along the tank, the traveling mechanism 1 may include a support frame body 11 and pulleys 12 arranged inside the support frame body 11. The support frame body 11 includes a first side plate 111, a second side plate 112, and a top plate 113 arranged between the upper ends of the first side plate 111 and the second side plate 112. The two ends of the axle of the pulley 12 are respectively fixed on the first side plate 111 and the second side plate 112.

[0041] The first side plate 111, the second side plate 112 and the top plate 113 form an inverted U-shaped support frame 11 for installing the pulley 12. Through holes may be provided on both the first side plate 111 and the second side plate 112. The two ends of the axle of the pulley 12 are respectively inserted into the through holes on the first side plate 111 and the second side plate 112 and fixed to the through holes. The pulley 12 can rotate smoothly within the support frame 11, and the rotation plane is parallel to the first side plate 111 / the second side plate 112.

[0042] Taking the upper edge of the pool wall as the track, the pulley 12 is adapted to the upper edge of the pool wall. When the pulley 12 slides on the upper edge of the pool wall, the first side plate 111 and the second side plate 112 are respectively on both sides of the pool wall, and the top plate 113 is on the upper side of the pool wall. The weights of the first side plate 111 and the second side plate 112 and the pressure of the top plate 113 can prevent the pulley 12 from displacing and derailing, and the first side plate 111 and the second side plate 112 also play a role in limiting the pulley 12.

[0043] When the pool is a square pool, the pulley 12 moves along a straight track. One such scaling device for coagulation tanks can be provided on the upper edges of the four pool walls, and each scaling device for coagulation tanks works simultaneously; or only one such scaling device for coagulation tanks can be used, and the scaling device for coagulation tanks is manually moved to the upper edge of the next wall surface, and each wall surface is cleaned in turn.

[0044] When the pool is a circular pool, the lengths of the first side plate 111 and the second side plate 112 are set according to the circumference of the pool to ensure that when the pulley 12 slides on the upper edge of the circular pool, the support frame 11 will not interfere with the sliding, and the entire traveling mechanism 1 can walk smoothly on the circular pool wall.

[0045] In order to clean any height of the pool wall, the connecting mechanism 2 may include a first telescopic rod 21. The upper end of the first telescopic rod 21 is connected to the outer wall of the first side plate 111. The lower end of the first telescopic rod 21 is rotatably connected to one end of a connecting rod 22 through a shaft. The rotation plane of the connecting rod 22 is perpendicular to the first side plate 111. A second telescopic rod 23 is connected between the side of the lower end of the first telescopic rod 21 facing away from the first side plate 111 and the connecting rod 22.

[0046] After the traveling mechanism 1 is placed on the upper edge of the pool wall, the first telescopic rod 21 can descend or ascend vertically along the pool wall. When it is necessary to clean a deeper position of the pool wall, the first telescopic rod 21 can be controlled to descend to reach the required length. When it is necessary to clean a shallower position of the pool wall, the first telescopic rod 21 can be controlled to ascend to reach the required length.

[0047] Since the pool bottom is generally bucket-shaped, the pool wall at the bottom has a certain angle, and the lower end of the first telescopic rod 21 is rotatably connected with a connecting rod 22, and the connecting rod 22 can swing at the lower end of the first telescopic rod 21, and the swinging plane is perpendicular to the first side plate 111; the second telescopic rod 23 is arranged on the side of the first telescopic rod 21 away from the walking mechanism 1, and the connecting rod 22 rotates in the direction away from the walking mechanism 1 following the contraction of the second telescopic rod 23. The extension and contraction of the second telescopic rod 23 can be adjusted according to the required angle, and the angle between the connecting rod 22 and the first telescopic rod 21 can be positioned.

[0048] When cleaning the bucket-shaped pool bottom, the first telescopic rod 21 is lowered to the vicinity of the pool bottom, and the second telescopic rod 23 is adjusted so that the descaling mechanism 3 on the connecting rod 22 contacts the inclined pool bottom wall, and then the second telescopic rod 23 stops moving, the angle between the connecting rod 22 and the first telescopic rod 21 is fixed, and the descaling mechanism 3 starts cleaning. If the slope of the pool bottom wall is deep, the first telescopic rod 21 can be gradually lowered to a set length, and the second telescopic rod 23 can be gradually adjusted to gradually clean the inclined pool bottom wall from shallow to deep. Generally, the cleaning of the inclined pool bottom wall can be completed by lowering it once or twice.

[0049] The method for judging whether the descaling mechanism 3 has contacted the pool bottom wall is to adjust the second telescopic rod 23 after lowering the first telescopic rod 21 to a set length. If the worker presses the button of the second telescopic rod 23 and feels that the second telescopic rod 23 cannot be changed, it means that the descaling mechanism 3 has contacted the pool bottom wall and descaling can be performed. The length of the second telescopic rod can also be adjusted according to the angle of the inclined pool bottom wall so that the descaling mechanism 3 contacts the pool bottom wall. Generally, the angle between the inclined pool bottom wall and the vertical pool bottom wall is 135 degrees.

[0050] The second telescopic rod 23 can be extended and retracted to allow the connecting rod 22 to form different angles with the first telescopic rod 21, so as to adapt to any height position of the cleaning bucket-shaped pool bottom.

[0051] When cleaning the vertical pool wall, the first telescopic rod 21 is appropriately retracted, and the second telescopic rod 23 is extended so that the connecting rod 22 is in the same straight line as the first telescopic rod 21. The first telescopic rod 21 can be gradually lowered by a certain length to clean the vertical pool wall from top to bottom, or the first telescopic rod 21 can be gradually raised by a certain length to clean the vertical pool wall from bottom to top. According to the liquid depth, it can be obtained that the first telescopic rod 21 can be controlled to extend to a certain length to reach the lower end of the vertical pool wall.

[0052] In order to automatically remove dirt on the pool wall, the descaling mechanism 3 may include a vibration motor 31 disposed on a side of the connecting rod 22 away from the second telescopic rod 23 and a shovel blade 32 disposed on the vibration motor 31 .

[0053] The length and diameter of the connecting rod 22 can be determined according to the specific working conditions, and it should be able to firmly install the descaling mechanism 3 and adapt to the pool wall with an inclined surface for cleaning. The vibration motor 31 can be fixed close to the end of the connecting rod 22 away from the first telescopic rod 21.

[0054] The pulley 12 of the traveling mechanism 1 slides on the upper edge of the pool wall of the coagulation tank. Adjust the first telescopic rod 21, and adjust the included angle between the connecting rod 22 and the first telescopic rod 21 through the second telescopic rod 23, so that the scraping blade 32 contacts the pool wall. Start the vibration motor 31, and the vibration of the vibration motor 31 drives the scraping blade 32 to vibrate. The vibrating scraping blade 32 scrapes the wall surface to remove dirt. The switch of the vibration motor 31 is arranged on the second side plate 112.

[0055] In a specific embodiment of the present utility model, in order to facilitate the rotation of the pulley 12, a rotating motor 13 is arranged on the outer wall of the second side plate 112, and the shaft of the rotating motor 13 is connected to the axle of the pulley 12. The rotating motor 13 can be fixed on the outer side surface of the second side plate 112 to drive the pulley 12 to rotate, and the steering and speed of the pulley 12 can be adjusted through the rotating motor 13.

[0056] In a specific embodiment of the present utility model, for the further stable operation of the traveling mechanism 1, auxiliary wheels 14 are arranged on the support frame 11 to assist in traveling. Specifically, both sides of the pulley 12 are respectively in contact with the first side plate 111 and the second side plate 112. The pulley 12 is located in the upper half of the first side plate 111, and auxiliary wheels 14 are arranged in the lower halves of both the first side plate 111 and the second side plate 112 to form a pair of auxiliary wheels; the axle of the auxiliary wheel 14 is perpendicular to the axle of the pulley 12, and the distance between the pair of auxiliary wheels is the wall thickness of the pool wall.

[0057] The pulley 12 travels on the upper edge of the pool wall, and the side part of the pulley 12 slides on the first side plate 111 and the second side plate 112. The pulley 12 runs more stably and vertically when clamped between the first side plate 111 and the second side plate 112. The pulley 12 is located in the upper half of the first side plate 111, and the lower parts of the two side plates respectively block both sides of the pool wall to prevent the pulley 12 from falling off.

[0058] For the further stability of traveling, a pair of auxiliary wheels are arranged in the lower halves of the first side plate 111 and the second side plate 112. When traveling, the pair of auxiliary wheels clamp the pool wall in the middle and slide on both sides of the pool wall respectively. The simultaneous operation of the pulley 12 and the pair of auxiliary wheels ensures the stable and smooth traveling.

[0059] In a specific embodiment of the present utility model, for the stable installation of the auxiliary wheel 14, the auxiliary wheel 14 may include a cuboid outer shell 141 with an opening at one end. A wheel 142 is arranged in the outer shell 141. Both ends of the axle of the wheel 142 are respectively inserted into the edges of the upper wall and the lower wall of the outer shell 141. Through openings are provided on both the first side plate 111 and the second side plate 112. The opening of the outer shell 141 is connected to the through opening. The outer shell 141 is located outside the first side plate 111 / second side plate 112. The part of the wheel 142 located outside the outer shell 141 passes through the through opening and contacts the pool wall.

[0060] Part of the wheel 142 is located in the outer shell 141, and part is located outside the outer shell 141. The axle of the wheel 142 is vertically fixed on the outer wall of the outer shell 141. After the outer shell 141 is connected to the through opening, part of the wheel 142 is located inside the support frame 11 and contacts the pool wall. The two horizontal wheels 142 form a pair of auxiliary wheels. The diameter of the wheel 142 is determined according to the distance between the pool wall and the first side plate 111, and the outer shell 141 can accommodate the wheel 142. The parts of both ends of the axle of the wheel 142 extending out of the outer shell can be bent, and the bent ends are connected to the second side plate 112, which further ensures the firmness of the auxiliary wheel 14.

The two pulleys 12 are arranged side by side in the support frame 11. The number of pairs of auxiliary wheels is two pairs, and the pairs of auxiliary wheels are arranged at the position directly below the pulleys 12.

[0062] The two pulleys 12 run on the pool wall one after the other. A pair of auxiliary wheels is arranged below each pulley 12. The two groups of wheels run simultaneously, and the walking is more stable and not easy to derail.

[0064] The shortest length when the first telescopic rod 21 retracts can meet the uppermost part of the dirt cleaning section of the dirt removing mechanism 3 on the pool wall. The longest length when the first telescopic rod 21 extends should meet the lowermost part of the pool bottom for the dirt removing mechanism 3 to clean. The diameter of the first telescopic rod 21 should be able to ensure stable support of the dirt removing mechanism 3 and withstand vibration. The specification of the first telescopic rod 21 is selected according to the depth of the pool body.

[0065] In a specific embodiment of the present utility model, the second telescopic rod 23 can be a hydraulic telescopic rod. A first connecting ear 26 is provided at a position near the end of the lower part of the movable rod of the first telescopic rod 21. A second connecting ear 27 is provided on the connecting rod 22.

[0067] The second telescopic rod 23 is a small hydraulic telescopic rod, and the stroke diameter is determined according to the specific working conditions. The two ends of the second telescopic rod 23 are respectively rotatably connected to the connecting ears on the first telescopic rod 21 and the connecting rod 22 through a shaft, which can enable the second telescopic rod 23 to flexibly drive the connecting rod 22 to rotate.

[0068] In a specific embodiment of the present utility model, in order to firmly fix the vibration motor 31, a motor base 33 is provided at the end of the connecting rod 22.

The vibration motor 31 is provided on the motor bracket 35. A head outer cover 36 is provided on the head of the vibration motor 31. The shovel blades 32 are evenly provided on the head outer cover 36.

[0069] The length diameter of the connecting rod 22 is determined according to the specific situation of the descaling work. In this embodiment, the length of the connecting rod 22 can be twice the length of the vibration motor 31. The four shock-absorbing springs 34 are connected between the motor base 33 and the motor bracket 35. The lower side surface of the motor base 33 is stably fixed at a position near the end of the connecting rod 22, and the rod wall of the connecting rod 22 is connected to the middle of the lower side surface of the motor base 33. The body of the vibration motor 31 is fixed on the motor bracket 35. When the vibration motor 31 vibrates, the four shock-absorbing springs 34 can play a role in shock absorption to prevent damage to components such as the connecting rod 22.

[0070] In order to firmly fix the shovel blades 32, a head outer cover 36 is fixed on the head of the vibration motor 31, and the shovel blades 32 are installed through the head outer cover 36. One side of the shovel blades 32 is set as an inclined surface to facilitate shoveling dirt.

[0071] When the entire connecting mechanism 2 is vertical, the shovel blades 32 should be able to contact the pool wall, and the second telescopic rod 23 can also be slightly extended to make the connecting rod 22 rotate towards the vertical pool wall, so that the shovel blades 32 are in close contact with the pool wall.

[0072] To prevent liquid from damaging the vibration motor 31, the vibration motor 31 is an explosion-proof and waterproof vibration motor.

Start the traveling structure to clean the pool wall for one week at this height. Since the depth of some pool walls is 2.5 m, the connecting mechanism 2 can be gradually lowered from top to bottom, and the pool wall can be cleaned at a certain depth step by step, from shallow to deep until the entire pool wall is cleaned.

[0075] The shoveled dirt deposits at the bottom of the pool and is discharged through the sewage outlet at the bottom of the pool when the pool is out of service.
