Description

Technical Field

[0001] This utility model relates to the field of receiving tanks, and in particular to a cleaning device for water receiving tanks and a water receiving tank. Background Technology

[0002] Water receiving tanks are used in the production of polyester fibers. These tanks must be cleaned regularly, otherwise scale will accelerate the corrosion process.

[0003] To better clean water receiving tanks, existing technologies include a water receiving tank, such as Chinese Patent Application No. CN202320021496.5, which includes a base, a tank body, and a drive device. The tank body is fixedly connected to the top of the base, and the drive device is fixedly connected to the side wall of the tank body. A cleaning device is provided inside the tank body. This utility model provides a water receiving tank that uses a cleaning device to clean the water tank. The water outlet valve allows water from the cleaning tank to flow into a hollow shaft. The water is then sprayed onto the inner wall of the tank through a nozzle on the hollow shaft. A drive motor then drives a rotating plate on the hollow shaft and a cleaning brush on the rotating plate, allowing the cleaning brush to clean the inner wall of the tank body. Finally, the control valve on the water outlet pipe is opened to allow water to drain out.

[0004] Existing technologies similar to the aforementioned water receiving tanks have the following problems: the cleaning mechanism is fixed inside the tank, making disassembly and maintenance cumbersome, and the contact area between the cleaning brush and the tank wall is small, resulting in poor cleaning effect.

[0005] Therefore, there is an urgent need for a cleaning device for water receiving tanks and a water receiving tank that can be easily disassembled and assembled, and improve the cleaning effect. Utility Model Content

[0006] To address the problems in existing technologies where the cleaning mechanism is fixed inside the tank, making disassembly and maintenance cumbersome, and the cleaning brush has a small contact area with the tank wall, resulting in poor cleaning performance, this utility model proposes a water receiving tank, the technical solution of which is as follows:

[0007] A cleaning device for a water receiving tank, the water receiving tank including a tank body and a sealing cover, the tank body being vertically arranged with an opening at the top, and having an openable and closable water inlet and outlet respectively; the sealing cover being detachably installed at the opening end of the tank body, a driving device being integrated on the top surface of the sealing cover, and a rotating shaft being coaxially rotatably arranged at the bottom center of the sealing cover, the driving device driving the rotating shaft to rotate about the tank body axis;

[0008] At least a plurality of mounting arm assemblies are provided on the outer wall of the rotating shaft along the axial direction. Each assembly includes a plurality of circumferentially distributed mounting arms. The axis of each mounting arm is perpendicular to the axis of the rotating shaft, and the circumferential angular position of each mounting arm assembly on the rotating shaft is consistent.

[0009] Multiple mounting arms arranged in a row along the axis of rotation and located at the same circumferential angle are fixedly connected to a cleaning brush plate at their ends. The length direction of the cleaning brush plate is parallel to the axis of rotation, and its working surface abuts against and adheres to the inner wall surface of the tank.

[0010] Furthermore, the mounting arm is rod-shaped, and stress-dispersing kits are provided between adjacent mounting arms in the same group of mounting arms; the stress-dispersing kit includes an arc-shaped connecting rod and half-sleeves on both sides thereon: the half-sleeves are axially split half-tubes, and the half-tubes of two adjacent stress-dispersing kits are sleeved on the same mounting arm. The mounting arm is partially provided with an external thread section, and a positioning sleeve is coaxially screwed onto the external thread section. The positioning sleeve can be coaxially sleeved onto a pair of half-tubes covering the mounting arm.

[0011] Furthermore, a rotating nozzle is installed on the bottom surface of the sealing cover, and the rotating nozzle is connected to the water inlet pipe on the top surface of the sealing cover through a pipe.

[0012] Furthermore, the cleaning brush plate includes a mounting plate and a brush module. The plate has an arc-shaped structure and its curvature matches the inner wall of the tank. A dovetail groove is formed along the length of one side of the cleaning brush plate facing the inner wall of the tank. The end of the dovetail groove facing the bottom of the tank is a closed end. The brush module is detachably mounted on the cleaning brush plate through the dovetail groove.

[0013] Furthermore, the brush module includes a working surface and an mounting surface. The working surface is provided with cleaning bristles, and the mounting surface is provided with a protrusion that matches the shape of the dovetail groove. The protrusion can be slidably inserted along the axial direction of the dovetail groove.

[0014] Furthermore, the closed end of the dovetail groove is provided with a through hole that penetrates the mounting plate along the axial direction.

[0015] Furthermore, the top of the sealing cover is provided with a lifting ring to facilitate the sealing cover and the drive device and rotating shaft integrated on the sealing cover.

[0016] According to an embodiment of the present invention, a water receiving tank is also provided, including any of the above-described cleaning devices for a water receiving tank.

[0017] Furthermore, a socket is provided at the center of the bottom of the water receiving tank. The end of the rotating shaft away from the sealing cover is inserted into the socket. The socket does not restrict the rotation of the rotating shaft, but it provides radial restraint to the rotating shaft.

[0018] The beneficial effects of this utility model are as follows: This technical solution integrates the drive device and rotating shaft into one unit through a detachable sealing cover design, enabling convenient disassembly and maintenance and solving the problem of cumbersome disassembly in the prior art. Simultaneously, by utilizing multiple sets of circumferentially distributed mounting arms and a cleaning brush plate structure, the cleaning brush plate conforms to the curved surface of the inner wall of the tank, increasing the contact area with the tank wall and significantly improving the cleaning effect, avoiding the defect of a small cleaning surface. Furthermore, the stress dispersion kit reduces the risk of stress damage to the mechanism, and the detachable design of the rotating nozzle and the dovetail groove of the brush module further enhances cleaning efficiency and ease of maintenance.

[0026] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0027] A cleaning device for a water receiving tank, the water receiving tank including a tank body 1 (which needs to be fixed during use) and a sealing cover 6. The tank body 1 is vertically arranged with an opening at the top, and has an openable inlet 2 and an outlet 3 on the tank body 1 (the inlet 2 and outlet 3 are equipped with valves, which are connected to external water inlet pipes and outlet pipes, or to other production processes, respectively). The sealing cover 6 is detachably installed at the open end of the tank body 1. The top surface of the sealing cover 6 is integrated with a drive device 10 (the drive device 10 is a geared motor, and the output shaft of the geared motor passes through the sealing cover 6 and is coaxially connected to a rotating shaft 11. The installation method and power source of the geared motor are common knowledge in industrial facilities and will not be described in detail here). The bottom center of the sealing cover 6 is coaxially rotatably provided with a rotating shaft 11, and the drive device 10 drives the rotating shaft 11 to rotate about the axis of the tank body 1.

[0028] Preferably, in this embodiment, a sealing ring is provided on the outer periphery of the bottom surface of the sealing cover 6, and the sealing cover 6 is fixed to the tank body 1 by a snap fastener (since sealing rings and snap fasteners are common applications in industrial facilities, they will not be described in detail in the embodiments and drawings to make the instructions and drawings clearer and more concise).

[0029] Two sets of mounting arms 12 are arranged axially on the outer wall of the rotating shaft 11. Each set has four circumferentially distributed mounting arms 12. The axis of each mounting arm 12 is perpendicular to the axis of the rotating shaft 11. The circumferential angular positions of each set of mounting arms 12 on the rotating shaft 11 are consistent.

[0030] A cleaning brush plate 17 is fixedly connected to two ends arranged in a row along the axis of rotation 11 and located at the same circumferential angle. The length direction of the cleaning brush plate 17 is parallel to the axis of rotation 11, and its working surface abuts against and adheres to the inner wall surface of the tank 1.

[0031] Preferably, the mounting arm 12 is rod-shaped, and stress-dispersing components 13 are provided between adjacent mounting arms 12 in the same group. The stress-dispersing components 13 include an arc-shaped connecting rod 14 and half-sleeves 15 on both sides thereof. The half-sleeves 15 are axially split half-tubes. The half-tubes of two adjacent stress-dispersing components 13 are sleeved on the same mounting arm 12. The mounting arm 12 is partially provided with an external thread section 121, and a positioning sleeve 16 is coaxially screwed onto the external thread section 121. The positioning sleeve 16 can be coaxially fitted onto a pair of half-tubes covering the mounting arm 12 to axially lock the pair of half-tubes. This effectively distributes the bending stress originally concentrated at the root of a single mounting arm 12 through the connecting rod and adjacent mounting arms 12, reducing local stress concentration and significantly enhancing the overall bending and torsional stiffness and fatigue strength of the mounting arm 12 group.

[0032] Preferably, a rotating nozzle 9 is installed on the bottom surface of the sealing cover 6. The rotating nozzle 9 is connected to the water inlet pipe 8 on the top surface of the sealing cover 6 through a pipe, integrating the spraying function into the rotating cleaning mechanism. While the brush plate is performing physical scrubbing, high-pressure water or cleaning liquid can be sprayed directly onto the tank wall surface and the brush plate through the rotating nozzle 9.

[0033] Preferably, the cleaning brush plate 17 includes a mounting plate 18 and a brush module 21. The plate has an arc-shaped structure with a curvature matching the inner wall of the tank 1. A dovetail groove 19 is formed along the length of the surface of the cleaning brush plate 17 facing the inner wall of the tank 1. The end of the dovetail groove 19 facing the bottom of the tank 1 is closed. The brush module 21 is detachably mounted on the cleaning brush plate 17 via the dovetail groove 19. Preferably, the brush module 21 includes a working surface and a mounting surface. The working surface is provided with cleaning bristles 23, and the mounting surface is provided with a protrusion 22 that matches the shape of the dovetail groove 19. The protrusion 22 can slide and insert along the axial direction of the dovetail groove 19. The bristles are the main wear parts. The insertion structure of the dovetail groove 19 and the protrusion 22 makes the replacement of the brush module 21 extremely quick, simple, and reliable. The user only needs to push the new module in or remove the old module along the axial direction, without the need for complex tools or disassembling the entire brush plate mounting arm 12.

[0034] Preferably, the closed end of the dovetail groove 19 is provided with a through hole 20 through the mounting plate 18 along the axial direction. When it is necessary to push the brush module 21 out of the dovetail groove 19 (towards the closed end), a rod-shaped tool can be used to push the protrusion 22 or the tail end of the brush module 21 from the back of the brush plate through this through hole 20, making disassembly easier (especially when the module is stuck tightly due to dirt or long-term use).

[0035] Preferably, the sealing cover 6 is provided with a lifting ring 7 at the top. The sealing cover 6, which has a certain weight and large volume, is equipped with a drive device 10 and a rotating shaft 11. The lifting ring 7 provides a convenient and reliable hanging point for standard lifting equipment (cranes, gantry cranes, manual hoists, etc.), which greatly simplifies the installation, disassembly, maintenance and transportation process of the entire cleaning device (or the water receiving tank containing it), and avoids the difficulties, damage and safety risks caused by manual lifting.

[0036] According to an embodiment of the present invention, a water receiving tank is also provided, including any of the above-described cleaning devices for a water receiving tank.

[0037] Preferably, the bottom center of the water receiving tank 1 has an inlet 4. The end of the rotating shaft 11 furthest from the sealing cover 6 is inserted into the inlet 4. The inlet 4 does not restrict the rotation of the rotating shaft 11, but it radially limits the rotation of the rotating shaft 11. Compared to relying solely on a single bearing support at the sealing cover 6, this "two-point support" (upper bearing rotational connection, lower inlet 4 limiting) significantly improves the rigidity and operational stability of the rotating shaft 11, preventing severe radial jumps or swaying when the rotating shaft 11 rotates at high speed or is subjected to uneven force. The improved stability of the rotating shaft 11 directly ensures that the cleaning brush 17 fixed to the end of the mounting arm 12 can always maintain a stable and uniform fit with the inner wall of the tank 1, improving the cleaning effect.

[0038] Summary of the usage method in this embodiment:

[0039] Preparation phase:

[0040] The brush module 21 is pre-installed. The protrusion 22 on the back of the brush module 21 is slid into the opening end of the dovetail groove 19 of the cleaning brush plate 17 and pushed to the closed end to complete the installation. If disassembly is difficult, a tool such as a top pin can be inserted into the through hole 20 at the closed end to help push the brush module 21 out.

[0041] The sealing cover 6 is hoisted by using a hoisting device to hook the hoisting ring 7 on the top of the sealing cover 6, and hoisting the sealing cover 6, which integrates the drive device 10 and the rotating shaft 11, as a whole. It is then slowly lowered into the tank body 1 and locked in place by the buckle between the tank body 1 and the sealing cover 6 to form a sealed space.

[0042] Finally, connect the external water supply or cleaning agent pipeline to the water inlet pipe 8 at the top of the sealing cover 6, and connect the pipeline to the internal rotating nozzle 9.

[0043] Operation phase:

[0044] Start the cleaning program and turn on the external water supply system. Water flows into the rotating nozzle 9 at the bottom of the sealing cover 6. Start the drive device 10, which drives the rotating shaft 11 to rotate the mounting arm assembly, thereby causing multiple sets of cleaning brushes 17 to perform circumferential scraping motion on the inner wall of the tank 1.

[0045] End phase:

[0046] Turn off the power to the drive unit 10, stop the rotation of the rotating shaft 11, and stop the external water (cleaning agent) supply.

[0047] Open the valve to drain the water. Open the outlet 3 at the bottom of tank 1 to discharge sewage and residual impurities (it may be decided whether outlet 3 needs to be closed during cleaning, depending on the situation). Inlet 2 needs to be closed during cleaning.

[0048] Maintenance and disassembly process:

[0049] Unlock the 6-locking buckle and lift out the 6-locking cover.

[0050] Disassemble the worn brush module 21 (depending on the degree of wear). Check the mounting arm assembly and stress dispersion kit 13 for integrity. Check the rotating nozzle 9 for proper function.

[0051] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
