Description

Technical Field

[0001] This invention relates to the field of cleaning equipment technology, and more specifically, to a pressure tank inner wall cleaning component, equipment, and cleaning method. Background Technology

[0002] As a key device in industrial fluid systems for stabilizing pressure and buffering flow, the cleanliness of the inner wall of a pressure tank directly affects system operating efficiency and media quality. Existing cleaning equipment is mostly designed for the cylindrical inner wall of the pressure tank. The brush structure struggles to effectively conform to the curved transition area between the inlet / outlet and the tank wall (such as the curved junction of the flange connection and the tank wall), making this area a cleaning blind spot. Long-term accumulation of dirt can easily lead to corrosion or media contamination. Furthermore, the brushes in existing cleaning devices are usually in a fixed, extended state. When inserted into or pulled out of the pressure tank opening, the brushes are prone to squeezing and colliding with the edge of the opening, causing bristles to fall off or the structure to deform. This not only shortens the brush's lifespan but also increases the difficulty of insertion / removal operations and may even damage the tank opening due to squeezing. Therefore, we propose a pressure tank inner wall cleaning component, equipment, and cleaning method. Summary of the Invention

[0003] The purpose of this invention is to provide a pressure tank inner wall cleaning component, equipment, and cleaning method to solve at least one of the above-mentioned technical problems.

[0004] This invention provides a pressure tank inner wall cleaning assembly, including a support tube and several folding mechanisms, with a second driving mechanism mounted on the support tube;

[0005] The second drive mechanism includes a threaded rod that is threaded to the support pipe, a lifting rod that is rotatably connected to the bottom of the threaded rod, and several push plates that are slidably connected to the support pipe are fixedly installed on the lifting rod.

[0006] The cleaning mechanism includes a fixed shaft rotatably connected to the output end of the folding mechanism, rotating blocks are fixedly installed at both ends of the fixed shaft, brushes are fixedly installed on the rotating blocks, and a second torsion spring for controlling the brushes to be perpendicular to the axis of the support tube is fitted on the fixed shaft. A push rod frame for pushing the rotating blocks is fixedly installed on the push plate.

[0007] The lifting rod drives the push plate to move, which enables the top rod frame to control the tilt angle of the rotating block; after the top rod frame disengages from the rotating block, the push plate pushes the folding mechanism to unfold, so that the rotated brush extends radially along the pressure stabilizing tank.

[0008] As a further description of the above technical solution, the folding mechanism includes several adjusting frames that slide inside the support tube, several connecting rods that are rotatably connected to the support tube via a support shaft, and several top plates, wherein the top plates are rotatably connected to the connecting rods.

[0009] Several tie rods are fixedly installed on the adjustment frame. An adjustment groove is opened on the connecting rod, and the tie rod slides in the adjustment groove. A first torsion spring for controlling the connecting rod to close to the support tube is installed on the support shaft.

[0010] As a further description of the above technical solution, each of the adjustment frames is provided with at least one push plate on its upper side, and the distance between the push plates and the top of the adjustment frame is equal.

[0011] As a further description of the above technical solution, each of the top plates corresponds to at least two sets of connecting rods, and the two sets of connecting rods are arranged in parallel.

[0012] As a further description of the above technical solution, the rotation direction and the orientation of the bristle tips of the brushes on the folding mechanisms of different layers are opposite.

[0013] As a further description of the above technical solution, the push rod frame includes a first push rod fixedly installed on the push plate, two sets of pull plates fixedly installed on the first push rod, the pull plates being slidably connected to the support tube, and a second push rod fixedly installed on the top of the pull plates.

[0014] This invention also discloses a pressure tank inner wall cleaning device, including the aforementioned pressure tank inner wall cleaning component, and a fixed base. A screw jack is installed on the fixed base, and a support plate that is rotatably connected to a support pipe is fixedly installed at the output end of the screw jack. The support plate is slidably connected to the fixed base.

[0015] As a further description of the above technical solution, a motor is installed on the support plate, a first gear is installed on the support tube, and a second gear that meshes with the first gear is fixedly installed at the output end of the motor.

[0016] As a further description of the above technical solution, it also includes a water guide ring rotatably installed on the support pipe, the water guide ring being connected to the water supply equipment, a water pipe being fixedly installed inside the support pipe, the water pipe being connected to the water guide ring, and several nozzles passing through the support pipe being connected and installed on the water pipe.

[0017] This invention also discloses a method for cleaning the inner wall of a pressure stabilizing tank, including using the aforementioned pressure stabilizing tank inner wall cleaning component, and the cleaning method further includes the following steps:

[0018] The rotating threaded rod drives the lifting rod to move the push plate, which in turn controls the tilt angle of the rotating block and the brush.

[0019] By adjusting the insertion depth of the support tube, the bristles of the brush come into contact with the transition area of ​​the pressure stabilizing tank. Rotating the support tube causes the brush to rotate and clean the transition area of ​​the pressure stabilizing tank.

[0020] The lifting rod continues to drive the push plate to move, causing the top rod frame to disengage from the rotating block, the end of the brush to be perpendicular to the axis of the support tube, and the push plate to contact the folding mechanism.

[0021] Continue rotating the threaded rod so that the lifting rod drives the push plate to unfold the folding mechanism until the brush contacts the inner wall of the cylindrical area of ​​the pressure stabilizing tank. Then rotate the support tube so that the brush follows the rotation and cleans the inner wall of the cylindrical area of ​​the pressure stabilizing tank.

[0022] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0023] 1. This invention enables flexible switching between two cleaning modes: cleaning the inner wall of the cylindrical area of ​​the pressure stabilizing tank and cleaning the inlet / outlet transition area. This effectively solves the problem that traditional cleaning equipment cannot take care of different areas simultaneously, and significantly improves the integrity and thoroughness of the overall cleaning of the pressure stabilizing tank.

[0024] 2. The folding mechanism and cleaning mechanism of this invention adopt a double folding design. When inserting or pulling out the pressure stabilizing tank, the brush and the supporting structure can be folded up to avoid interference and squeezing with the tank opening. This not only reduces the difficulty of equipment operation, but also effectively reduces the loss of brush bristles due to squeezing and extends the service life of the brush.

[0025] 3. By cooperating with the first push rod, the second push rod, and the rotating block, and combining the elastic reset function of the second torsion spring, the present invention can precisely control the tilt angle of the brush within the range of 0-90 degrees, so that the upper / lower side brushes can respectively conform to the curved surface structure of the upper / lower transition area of ​​the pressure stabilizing tank, thereby achieving directional cleaning of the transition area and significantly improving the cleaning effect of complex structural areas.

[0026] 4. After the brush of the present invention unfolds to the vertical tank wall, the folding mechanism can continue to unfold, so that the brush continues to extend radially along the pressure stabilizing tank, effectively expanding the cleaning radius of the equipment, adapting to pressure stabilizing tanks of different diameters, and greatly improving the versatility and application range of the equipment.

[0027] 5. The design of the fixed base of this invention, which can be detachably installed on the inlet and outlet flanges of the pressure tank through fasteners, combined with the rotating connection structure of the support pipe and the support plate, allows the insertion, removal and component replacement of the equipment to be completed with only simple tools, which greatly reduces the time and cost of equipment installation, commissioning and maintenance.

[0042] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0043] Reference Figures 1 to 13 This embodiment discloses a pressure tank inner wall cleaning component and equipment, including a support pipe 1 and a fixed seat 2. The support pipe 1 passes through the fixed seat 2 and has several guide grooves 11. Several fixed plates 12 are fixedly installed on the support pipe 1, and limit rods 13 are inserted into the fixed plates 12. A support cylinder 21 is fixedly installed on the fixed seat 2, and a screw jack 22 is fixedly installed on the support cylinder 21. A support plate 23 that is rotatably connected to the support pipe 1 is fixedly installed at the output end of the screw jack 22. The fixed seat 2 and the support plate 23 are slidably connected by a telescopic rod 24. When the cleaning component is in use, the fixed seat 2 is detachably installed on the flange of the pressure tank inlet or outlet through fasteners, thereby enabling the support pipe 1 to be inserted into the pressure tank.

[0044] Reference Figure 1 and Figure 3 A first drive mechanism 3 is mounted on the support plate 23. The first drive mechanism 3 includes a motor 31 fixedly mounted on the support plate 23 and a first gear 32 mounted on the support tube 1. A second gear 33 that meshes with the first gear 32 is fixedly mounted on the output end of the motor 31. The output end of the motor 31 drives the second gear 33 to rotate, and through meshing transmission, drives the first gear 32 and the support tube 1 to rotate.

[0045] Reference Figure 1 , Figures 3 to 10A second drive mechanism 4 is installed on the support tube 1. The second drive mechanism 4 includes a threaded rod 41 that is threaded to the support tube 1. A lifting rod 42 is rotatably connected to the bottom of the threaded rod 41. Several push plates 43 are fixedly installed on the lifting rod 42. The push plates 43 are slidably connected to the corresponding guide grooves 11. A first push rod 44 is fixedly installed on the two sets of push plates 43 on the lower side. Two sets of pull plates 45 are fixedly installed on the first push rod 44. The pull plates 45 are parallel to the axis of the support tube 1. A second push rod 46 is fixedly installed on the top of the pull plates 45. The lower pull plates 45 are slidably connected to the support tube 1. A limit groove 47 is opened on the upper pull plate 45. The limit rod 13 is inserted into the limit groove 47 and slides, thereby realizing the sliding of the upper pull plate 45 on the support tube 1.

[0046] Reference Figures 6 to 12 The support tube 1 is equipped with several arrayed folding mechanisms 5. Each folding mechanism 5 includes an adjustment frame 51 that slides inside the support tube 1 and a connecting rod 52 that is rotatably connected to the support tube 1 via a support shaft 55. The support shaft 55 is located in the guide groove 11. The lifting rod 42 passes through the adjustment frame 51. Each adjustment frame 51 has at least one push plate 43 on its upper side, and the distance between the push plate 43 and the top of the adjustment frame 51 is equal. When the push plate 43 descends and contacts the adjustment frame 51, it can push the adjustment frame 51 to descend as well.

[0047] Several pull rods 53 are fixedly installed on the adjusting frame 51. An adjusting groove 54 is opened on the connecting rod 52. The pull rod 53 slides in the adjusting groove 54. A first torsion spring 56 is fitted on the support shaft 55. One end of the first torsion spring 56 is fixedly connected to the connecting rod 52, and the other end is fixedly connected to the support tube 1. The first torsion spring 56 is used to make the connecting rod 52 close to the support tube 1 until it reaches the limit, that is, the bottom end of the connecting rod 52 abuts against the support tube 1.

[0048] The folding mechanism 5 also includes a top plate 57, which is rotatably connected to the connecting rod 52. Each top plate 57 corresponds to at least two sets of connecting rods 52, and the two sets of connecting rods 52 are arranged in parallel to ensure that the top plate 57 remains parallel to the axis of the support tube 1 during unfolding or folding. When the adjusting frame 51 drives the pull rod 53 to descend, the two sets of pull rods 53 slide in the corresponding adjusting grooves 54, thereby enabling the connecting rod 52 to rotate around the support shaft 55 and compress the first torsion spring 56, thus controlling the unfolding of the top plate 57 and reducing the distance between the top plate 57 and the inner wall of the pressure tank.

[0049] Reference Figure 2 , Figure 6 , Figures 10 to 13A number of cleaning mechanisms 6 are installed on the top plate 57. In this embodiment, a set of cleaning mechanisms 6 is installed on each top plate 57 on the upper side, and two sets of cleaning mechanisms 6 are installed on each top plate 57 on the lower side. The cleaning mechanism 6 includes a fixed shaft 61 that is rotatably connected to the top plate 57. Rotating blocks 62 are fixedly installed at both ends of the fixed shaft 61. After the first push rod 44 and the second push rod 46 abut against the corresponding rotating blocks 62, they push the rotating blocks 62 to rotate around the fixed shaft 61.

[0050] A brush 63 is fixedly mounted on the rotating block 62. A through hole 64 is provided on the rotating block 62, allowing the upper pull plate 45 to be inserted into the through hole 64. This prevents interference and collision between the upper pull plate 45 and the rotating block 62, ensuring the stable action of the second push rod 46 on the rotating block 62. A second torsion spring 65 is fitted onto the fixed shaft 61. One end of the second torsion spring 65 is fixedly connected to the top plate 57, and the other end is fixedly connected to the fixed shaft 61. The second torsion spring 65 drives the brush 63 to rotate perpendicular to the axis of the support tube 1, i.e., the brush 63 is perpendicular to the inner wall of the pressure stabilizing tank. When the brush 63 is perpendicular to the inner wall of the pressure stabilizing tank, the limiting block on the fixed shaft 61 can limit and prevent rotation of the fixed shaft 61, thus ensuring the stability of the brush 63 angle adjustment. When the brush 63 is parallel to the axis of the support tube 1, the fixed shaft 61 is also limited and prevented from rotating. Therefore, in this embodiment, the fixed shaft 61 can only rotate within a 90-degree range.

[0051] To address the cleaning of the transition area between the inner wall of the pressure tank and the inlet and outlet, when the brush 63 is parallel to the axis of the support pipe 1, the brush 63 on the upper top plate 57 is positioned at the top of the top plate 57 with the bristles of the brush 63 pointing upwards. At least one set of brushes 63 is provided at the bottom of the lower top plate 57 with the bristles of the brush 63 pointing downwards. The brushes 63 on the upper and lower top plates 57 rotate in opposite directions. When the first push rod 44 and the second push rod 46 descend below the corresponding fixed shaft 61, the restriction of the vertical position of the brush 63 by the first push rod 44 and the second push rod 46 is gradually released. At this time, under the action of the second torsion spring 65, the end of the brush 63 gradually rotates towards the inner wall of the pressure tank. When the first push rod 44 and the second push rod 46 stop, the brush 63 stops rotating. Therefore, by controlling the position of the first push rod 44 and the second push rod 46, the angle adjustment of the brush 63 within the range of 0-90 degrees can be controlled. When the brush 63 is tilted, by controlling the position of the support tube 1, the upper brush 63 can tilt and contact the transition area on the upper side of the pressure tank, and the lower brush 63 can tilt and contact the transition area on the lower side of the pressure tank, thereby achieving cleaning of the transition area between the inner wall of the pressure tank and the inlet and outlet, and improving the cleaning effect.

[0052] Reference Figures 2 to 7A water guide ring 7 is rotatably connected to the support pipe 1. The water guide ring 7 is connected to the water supply equipment. The connection between the water guide ring 7 and the support pipe 1 is sealed by a sealing ring. A water pipe 8 is fixedly installed inside the support pipe 1. The water pipe 8 is connected to the water guide ring 7. The water pipe 8 passes through the push plate 43 and the adjusting bracket 51. Several nozzles 9 are connected and installed on the water pipe 8. The nozzles 9 pass through the support pipe 1 and are used to spray cleaning fluid onto the inner wall of the pressure stabilizing tank to assist in cleaning.

[0053] This embodiment also discloses a method for cleaning the inner wall of a pressure stabilizing tank, including the following steps:

[0054] S1. Insert the support tube 1 into the pressure stabilizing tank from the opening. The support plate 23 abuts against the flange at the opening of the pressure stabilizing tank and is fixed by bolts or limit pins, so that the support tube 1 is coaxial with the pressure stabilizing tank. Before the support tube 1 is inserted, the folding mechanism 5 is in the closed state, and the brush 63 of the cleaning mechanism 6 is parallel to the axis of the support tube 1.

[0055] S2. Manually rotating the threaded rod 41 drives the lifting rod 42 to move towards the end of the support tube 1 closer to the folding mechanism 5. The lifting rod 42 drives the push plate 43, the first top rod 44, the pull plate 45, and the second top rod 46 to move down. When the height of the first top rod 44 and the second top rod 46 is lower than the height of the corresponding fixed shaft 61, the fixed shaft 61 rotates under the drive of the second torsion spring 65, thereby driving the rotating block 62 and the brush 63 to rotate to the tilt. The rotation angle of the brush 63 is controlled by limiting the rotating block 62 through the top rod.

[0056] S3. Manually adjust the screw jack 22 to move the support plate 23 and support pipe 1 inside the pressure stabilizing tank, so that the upper brush 63 contacts the transition area of ​​the pressure stabilizing tank.

[0057] S4, the output end of the motor 31 drives the second gear 33 to rotate, which in turn drives the first gear 32, support tube 1, second drive mechanism 4, folding mechanism 5 and cleaning mechanism 6 to rotate through meshing transmission, so as to realize the cleaning of the transition area of ​​the pressure stabilizing tank by the brush 63; during the rotation of the brush 63, the water supply equipment sprays water onto the inner wall of the pressure stabilizing tank through the water guide ring 7, water pipe 8 and nozzle 9 to assist in cleaning;

[0058] S5. After the area covered by the brush 63 is cleaned, repeat step S2 and adjust the tilt angle of the brush 63 again so that the brush 63 can rotate to other uncleaned positions in the transition area of ​​the pressure tank. Then repeat step S4 to clean the area.

[0059] S6. After cleaning the transition area of ​​the upper pressure tank, manually adjust the screw jack 22 to move the support plate 23 and support pipe 1 inside the pressure tank, so that the brush 63 on the lower side contacts the transition area on the lower side of the pressure tank. Then repeat steps S4 and S5 to clean the transition area on the lower side of the pressure tank.

[0060] S7. After cleaning the transition area of ​​the pressure tank, manually rotate the threaded rod 41 to drive the lifting rod 42 to move continuously towards the end of the support tube 1 close to the folding mechanism 5. After the first top rod 44 and the second top rod 46 are both disengaged from the corresponding rotating block 62, the end of the brush 63 remains perpendicular to the axis of the support tube 1. At this time, the push plate 43 contacts the adjusting frame 51. Continue to rotate the threaded rod 41 so that the lifting rod 42 drives the push plate 43 to push the adjusting frame 51 to slide in the support tube 1. The pull rod 53 moves with the adjusting frame 51 and slides in the adjusting groove 54, so that the connecting rod 52 rotates around the support shaft 55 and compresses the first torsion spring 56. The connecting rod 52 drives the top plate 57 and the cleaning mechanism 6 installed on it to unfold until the brush 63 contacts the inner wall of the pressure tank.

[0061] S8. Repeat steps S3 and S4 to control the brush 63 to rotate and move along the axis of the pressure stabilizing tank, thereby cleaning the inner wall of the cylindrical area of ​​the pressure stabilizing tank.

[0062] This invention enables two cleaning modes for the inner wall of the cylindrical area and the transition area of ​​the pressure stabilizing tank, resulting in a more comprehensive cleaning effect. Both the folding mechanism 5 and the cleaning mechanism 6 can be folded, thereby avoiding interference and squeezing between the brush 63 and the opening of the pressure stabilizing tank when it is inserted or pulled out. This reduces the difficulty of inserting or pulling out the cleaning mechanism 6 and avoids the problem of the brush bristles of the brush 63 being squeezed and falling off due to pressure on the opening of the pressure stabilizing tank. Moreover, the double folding of the brush 63 and the folding mechanism 5 further increases the cleaning radius of the pressure stabilizing tank, making it more applicable.

[0063] Of course, the cleaning steps in this embodiment are not a limitation on the cleaning operation. That is, the cleaning method in this embodiment can also first clean the inner wall of the cylindrical area of ​​the pressure stabilizing tank, and then clean the transition area of ​​the pressure stabilizing tank.

[0064] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
