TECHNICAL FIELD
[0001] Embodiments of the present disclosure relate to the technical field of circulating water treatment, in particular, to an automatic water replenishing device for a circulating water pool. BACKGROUND
[0002] At present, alumina plants belong to large water users, and a large amount of production water is needed in the causticization process of alumina production. In order to ensure the smooth progress of the production process, the water quantity in the water storage pool needs to reach the requirement. In order to reduce the use of new water, improve the reuse rate of production wastewater and save energy and reduce consumption, the water in the water storage pool should use circulating water or secondary use water as much as possible. Therefore, the application of circulating water system in alumina plants is very important.
[0003] The circulating water system includes a water storage pool, a circulating water pump, a cooling tower (or a heat exchanger), a water quality treatment device (such as a filter, a dosing system), and a pipeline network. In the entire circulating process, the water in the water storage pool is transported to production equipment (such as an evaporator, a reaction kettle) by the circulating water pump for cooling or participating in process reaction. When the water absorbs heat or contacts chemicals in the production equipment, the temperature rises or is contaminated, flows into the cooling tower for cooling (by evaporation or air cooling), and enters the filter to remove suspended solids. The finally treated water returns to the water storage pool, mixes with new water, and is used again, forming a closed loop circulation.
[0004] For the filter used in the circulating water system, the commonly used one is a Y-shaped filter. When the liquid containing impurities enters the filter core through the Y-shaped pipe body inlet, the impurities are intercepted inside the filter core, and the medium passes through the filter core and flows out through the Y-shaped pipe body outlet. With the passage of time, the impurities in the filter core gradually accumulate to a certain extent, which easily causes the filter core to be blocked. At this time, it is necessary to stop the machine, disassemble the end cover of the Y-shaped filter, and replace the filter core, which affects the normal use of the equipment.

DETAILED DESCRIPTION
[0048] The present disclosure will be further described below in conjunction with the drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the present disclosure, but not to limit the present disclosure.

Moreover, the "upper", "upper" and "upper" of the first feature to the second feature include the vertical direction of the first feature above and oblique above the second feature, or only indicates that the horizontal height of the first feature is higher than that of the second feature. The "lower", "lower" and "lower" of the first feature to the second feature include the vertical direction of the first feature below and oblique below the second feature, or only indicates that the horizontal height of the first feature is less than that of the second feature.
[0052] In the description of the present embodiment, the terms "upper", "lower", "left", "right", and the like, orientation or positional relationship are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of description and simplification of operation, and do not indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the present disclosure.
[0053] In addition, in the description of the present application, the terms "first", "second", and the like are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.
[0054] As shown in Figures 1-5 , Figure 11 The automatic water replenishing device for circulating pool in an embodiment of the present disclosure is shown, which comprises: a pool body 1 having a water inlet 101 and a water outlet 102; a Y-shaped filter body 2 is arranged at the water inlet 101, and the Y-shaped filter body 2 has a filter cavity 201; a filter cartridge 3 is arranged in the filter cavity 201; further comprising: a cleaning pipe 4 is slidably connected with the Y-shaped filter body 2 and abuts against the inner wall of the filter cartridge 3, the sliding direction of the cleaning pipe 4 is parallel to the axial direction of the filter cartridge 3, the cleaning pipe 4 has a force applying part 401, the force applying part 401 penetrates through the Y-shaped filter body 2, and the force applying part 401 is configured to be driven to slide along the axial direction of the filter cartridge 3 after being subjected to an external force, so as to remove impurities on the inner wall of the filter cartridge 3.
[0055] At present, when facing filter core blockage, the device is usually stopped first, and then the Y-shaped filter end cover is disassembled to replace the filter core, but this way will interrupt the normal operation of the equipment, so as to realize the cleaning without stopping the machine, and then a cleaning pipe 4 which can slide along the axial direction of the filter cartridge 3 is arranged in the filter cartridge 3 and abuts against the inner wall thereof, and a force applying part 401 is integrally formed or welded on the cleaning pipe 4, the force applying part 401 penetrates through the Y-shaped filter body 2 to the outside space, the force applying part 401 is manually pulled or pushed to control the movement of the moving end 403 of the cleaning pipe 4 to clean the dirt, prolong the service life of the filter cartridge 3, or be stationary in the filter cartridge 3, and the thickness thereof cannot be too large to avoid affecting the normal filtration.
[0056] In addition, the entire automatic water replenishing device is composed of the pool body 1, a water pump, a liquid level meter 12, a sensor and the like. The automatic water replenishing is used to achieve the required water amount in the water storage pool, avoid the water overflow due to the excessively high liquid level, or the insufficient water supply amount due to the excessively low liquid level, so as to reduce the actual suction stroke of the water pump and damage the water pump. Specifically, the liquid level meter 12 can adopt the buoyancy measurement principle or the ultrasonic measurement principle to monitor the liquid level height of the pool. The liquid level height information is transmitted to the control box through the sensor. The control box controls the opening and closing of the electric valve according to the information. The valve and the water pump are opened. The water enters from the water inlet 101 after being filtered by the Y-shaped filter. Then, the circulating water in the pool body 1 is discharged to other equipment from the water outlet 102. When the liquid level height in the pool body 1 rises to the highest value in the set range, the liquid level meter 12 senses the signal and transmits it to the control box to close the electric valve. The water storage pool is automatically replenished in time and in an appropriate amount without manual intervention.
[0057] As shown in Figures 1-5 、 Figure 11 In some examples, the cleaning pipe 4 is a cleaning corrugated pipe. The cleaning pipe 4 has a fixed end 402 and a moving end 403. The fixed end 402 is connected with the Y-shaped filter main body 2. The moving end 403 has a force applying part 401. The force applying part 401 is configured to be driven by an external force to move the moving end 403 axially away from the fixed end 402 along the filter cylinder 3, so as to remove the impurities on the inner wall of the filter cylinder 3.
[0058] Further, the compression or stretching state of the cleaning pipe 4 (cleaning corrugated pipe) is controlled to control whether it is cleaned. The cleaning pipe 4 (cleaning corrugated pipe) in the compression state does not cover a large range of the inner wall of the filter cylinder 3 and does not affect the normal use. After being stretched, the moving end 403 can slide on the inner wall of the filter cylinder 3 to clean the impurities and avoid blockage.
[0059] The fixed end 402 can be connected with the Y-shaped filter main body 2 through an annular protrusion clamping or a bolt. The force applying part 401 is integrally formed or welded at the moving end 403 of the fixed end 402. The force applying part 401 is arranged to penetrate the Y-shaped filter main body 2 to the outside space. The force applying part 401 is manually pulled or pushed to control the moving end 403 of the cleaning pipe 4 to move to clean the impurities or to be compressed in the filter cylinder 3.
[0060] Specifically, the cleaning pipe 4 is generally in a corrugated tube shape, which can realize a large axial movement without affecting the structural strength, facilitating comprehensive impurity cleaning in the filter cartridge 3. In addition, the cleaning pipe 4 can be made of materials such as rubber or high-strength plastic. Since the filter cartridge 3 is sleeved on the outer wall of the cleaning pipe 4, the cleaning pipe 4 made of the above materials can support the filter cartridge 3 to a certain extent, avoiding deformation of the filter cartridge 3 during use. The reason for the deformation is that the cylindrical filter cartridge 3 has a relatively thin overall thickness and is made of metal. In the case of impurity blockage, continuing to filter can cause uneven overall stress, thereby deforming. In addition, reinforcing ribs can be arranged inside the cleaning pipe 4 to enhance the structural stability thereof.
[0061] As shown in Figure 3 , Figure 4 , Figure 7 , Figure 11 indicated, in some examples, the Y-shaped filter body 2 also has an opening 202 connected with the filter cavity 201. The circulating water pool automatic water replenishing device further comprises: an end cover 5 detachably arranged at the opening 202, the fixed end 402 is connected with the end cover 5, and the force applying part 401 penetrates through the end cover 5.
[0062] Generally, the end cover 5 is detachably arranged at the opening 202 to facilitate workers to detach and replace the filter cartridge 3. The detachable form is generally bolted. Corresponding threaded holes are arranged at the edge of the opening 202 of the Y-shaped filter body 2 and the end cover 5, and the end cover 5 is fixed at the opening 202 by bolts. Alternatively, a clamp is used for connection. A clamp groove is arranged at the opening 202 of the Y-shaped filter body 2 and the end cover 5, respectively. The clamp is sleeved in the groove, and the clamp is tightened by tightening the bolt on the clamp, so that the end cover 5 is tightly fixed at the opening 202.
[0063] Further consideration, since the fixed end 402 of the cleaning pipe 4 is connected with the Y-shaped filter body 2 by the annular protrusion or the like, the connection stability needs to be improved, and it is not convenient to install. Therefore, by means of the introduced end cover 5, the fixed end 402 and the plane of the end cover 5 are connected in the above-mentioned manner. After the end cover 5 is detached, the cleaning pipe 4 can also be directly detached, which is convenient for synchronous maintenance operation;
[0064] In addition, the force applying part 401 penetrates through the end cover 5 to the outside, which is convenient for applying external force. At the same time, an annular sliding sealing structure needs to be arranged to avoid leakage. Specifically, an annular groove is arranged on the end cover 5, and a sealing ring is installed in the groove. The sealing ring tightly fits the outer wall of the force applying part 401. When the force applying part moves in the axial direction under the action of external force, the sealing ring can slide along with it.
[0065] As shown in Figure 5 , Figure 7 , Figure 10 , Figure 11As shown, in some examples, the force applying part 401 has a ring-shaped magnetic force part 4010 for driving the moving end 403 to axially approach the fixed end 402 along the filter cartridge 3.
[0066] To improve the operation convenience and ensure that the cleaning pipe 4 can be stably kept in the compressed state when compressed, and to avoid the need to continuously apply external force required for compression, a ring-shaped magnetic force part 4010 is welded on the outer wall of the cylindrical force applying part 401, which can be adsorbed on the end cover 5 made of metal material.
[0067] In specific use, in the circulating filtering process, the ring-shaped magnetic force part 4010 is adsorbed on the end cover 5 made of metal material and stably kept in the compressed state, while when blocked, the force applying part 401 is pushed to separate the two, and the moving end 403 will axially move away from the end cover 5 along the filter cartridge 3 to complete the cleaning action; and finally reset to the compressed state.
[0068] As shown in Figure 3 , Figure 4 , Figure 6 , Figure 7 , Figure 9 As shown, in some examples, the circulating pool automatic water replenishing device further comprises a support ring 6 arranged in the filter cartridge 3, abutting against the inner wall of the filter cartridge 3 and located at one side of the fixed end 402.
[0069] To further improve the structural stability of the filter cartridge 3 and avoid deformation caused by uneven stress, the support ring 6 is arranged at one end of the fixed end 402, so that the cleaning pipe 4 in the compressed state with the end cover 5 can be stably supported from both ends of the inner wall of the filter cartridge 3 during long-term operation.
[0070] In addition, when the filter cartridge 3 is installed, the support ring 6 can also be used as a positioning component and integrally formed or welded with the Y-shaped filter main body 2, so that the staff can accurately install the filter cartridge 6. The filter cartridge 3 and the support ring 6 can be in interference fit or clearance fit. The interference fit can make the filter cartridge 3 and the support ring 6 tightly combined to enhance the stability, and the clearance fit can facilitate the installation and disassembly of the filter cartridge 3, and also allow the filter cartridge 3 to have a small thermal expansion and contraction displacement to a certain extent.
[0071] As shown in Figure 4 , Figures 6-9 As shown, in some examples, the circulating pool automatic water replenishing device further comprises a plurality of support rods 7 arranged in the filtering cavity 201 and uniformly arranged circumferentially along the support ring 6, both ends of each support rod 7 are connected to the support ring 6 and the end cover 5 respectively, and each support rod 7 is tightly abutted to the inner wall of the cleaning pipe 4.
[0072] A plurality of support rods 7 are arranged uniformly along the circumferential direction of the support ring 6, and the two ends thereof are respectively inserted into the support ring 6 and the end cover 5, thereby forming a stable frame structure, which comprehensively supports the filter cartridge 3 from the inside, and the relative positions of the two can also be accurately determined.
[0073] More importantly, the plurality of support rods 7 are arranged uniformly along the circumferential direction of the support ring 6 and abut against the inner wall of the cleaning pipe 4, so that the cleaning pipe 4 plays a guiding role when it is axially moved under external force, thereby avoiding deviation or distortion during movement, and ensuring the uniformity and stability of the cleaning effect. In addition, the cleaning pipe 4 can better fit the inner wall of the filter cartridge 3, thereby effectively removing impurities at various positions of the inner wall of the filter cartridge 3.
[0074] As shown in Figure 4 , Figures 6-9 In some examples, the circulating water tank automatic water replenishment device further comprises a cleaning support frame 8 arranged in the filter cavity 201 and located between the support ring 6 and the end cover 5 and abutting against the inner wall of the filter cartridge 3. The plurality of support rods 7 are in sliding connection with the cleaning support frame 8. The cleaning support frame 8 is configured to be pushed by the moving end 403 after the moving end 403 moves axially away from the fixed end 402 along the filter cartridge 3, for cleaning and supporting the inner wall of the filter cartridge 3.
[0075] A plurality of reset springs 9 are correspondingly sleeved on the plurality of support rods 7, and the two ends of each reset spring 9 are connected with the support ring 6 and the cleaning support frame 8, respectively. The reset spring 9 is used for elastically pushing the cleaning support frame 8, so as to reset the cleaning support frame 8.
[0076] The cleaning support frame 8 is installed between the support ring 6 and the end cover 5 and abuts against the inner wall of the filter cartridge 3, thereby providing support force from the middle region inside the filter cartridge 3 to avoid deformation. The cleaning support frame 8 and the cleaning pipe 4 both abut against the inner wall of the filter cartridge 3, so that the moving end 403 of the cleaning pipe 4 pushes the cleaning support frame 8 after moving, and the position of the cleaning support frame 8 can be finely adjusted according to actual needs. When the operating conditions of the circulating water system change, for example, the water flow rate and the impurity content change, the position of the cleaning support frame 8 can be adjusted by the cleaning pipe 4, so as to change the support strength and the cleaning effect on the filter cartridge. Meanwhile, the plurality of support rods 7 are in sliding connection with the cleaning support frame 8, thereby providing a guiding role for the sliding of the cleaning support frame 8. Even if the position of the cleaning support frame 8 is changed, the adjustment is only within a certain range, thereby avoiding that the cleaning support frame 8 which is only in sliding connection does not have a reset capability, so as to be unable to reset after being pushed. Even if the cleaning pipe 4 moves under the blockage of the cleaning support frame 8, it cannot completely cover all the inner walls of the filter cartridges 3, but only moves at the inner walls of the middle and lower regions. In actual operation, impurities are mostly concentrated and blocked at the inner walls of the middle and lower regions, so that even if the cleaning support frame 8 is additionally provided, it will not excessively affect the function of the cleaning pipe 4, but drives the circular cleaning support frame 8 to jointly clean the inner wall of the filter cartridge 3.
[0077] In addition, the cleaning support frame 8 can be fixedly welded on the support rod 7, as long as a position for the movable end 403 of the cleaning pipe 4 to move is avoided, and the support ring 6 and the end cover 5 provide support for the filter cartridge 3.
[0078] Specifically, the cleaning support frame is generally designed as a square ring or a circular ring structure, and the abutting surface is matched with the inner wall of the filter cartridge, and the sliding connection can be achieved by opening a hole (such as Figure 6 As shown, the support rod 7 penetrates the hole and is in interference fit, so that the cleaning support frame 8 is stably slid.
[0079] The reset spring 9 is added to realize automatic reset of the cleaning support frame 8, and the restriction on the movement range of the movable end 403 of the cleaning pipe 4 is released. The movable end 403 of the cleaning pipe 4 can push the cleaning support frame 8 away from the end cover 5 at one end of the filter cartridge 3 under the action of an external force, and more comprehensively clean the inner wall of the filter cartridge 3. In the process of compressing the cleaning pipe 4, the cleaning support frame 8 is reset to the original position under the action of the reset spring 9, and continues to provide support for the inside of the filter cartridge 3 at the original position (the middle region inside the filter cartridge 3).
[0080] Specifically, the reset spring 9 is sleeved on each support rod 7, and the two ends of each reset spring 9 are connected with the support ring 6 and the cleaning support frame 8, respectively, which can be welded.
[0081] As shown in Figure 7 In some examples, the circulating water pool automatic water replenishing device further comprises: the end cover 5 is arranged at the opening 202 by a fastener.
[0082] The detachable connection of the end cover 5 and the Y-shaped filter main body 2 is completed by the fastener, which facilitates workers to disassemble. Corresponding threaded holes are arranged at the edges of the opening 202 of the end cover 5 and the Y-shaped filter main body 2, and the end cover 5 is fixed at the opening 202 by the fastener.
[0083] As shown in Figures 1-2 In some examples, the circulating water pool automatic water replenishing device further comprises: a pipeline 10 is in communication with the water inlet 101; and a water softener 11 is arranged on the pipeline 10 and used for softening the incoming water.
[0084] The circulating water pool automatic water replenishing device further comprises: a liquid level meter 12 arranged on the pool body 1 and used for detecting the liquid level height in the pool body 1.
[0085] Water softener 11 is additionally installed on pipeline 10 before water inlet filtration, so as to achieve the purpose of softening the inlet water. If the hardness of the circulating water is high, calcium, magnesium and other ions in the water can form scale on the surface of the production equipment and the pipes of the circulating water system, cooling tower and other components, which can accelerate the corrosion of the metal components. The softened water can improve this situation, reduce the corrosion of the equipment by corrosive substances in the water, and ensure the structural integrity and performance stability of the equipment.
[0086] It should be noted that the above examples are only used to illustrate the technical solutions of the present disclosure and are not limiting. Although the present disclosure has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical solutions of the present disclosure can be modified or replaced equivalently without departing from the spirit and scope of the technical solutions of the present disclosure, which should be covered in the scope of the claims of the present disclosure.
