Description

Technical Field

[0001] This utility model relates to the field of environmental protection equipment manufacturing technology, and in particular to a liquid flow proportioning device. Background Technology

[0002] During the operation of a magnetic coagulation sedimentation water treatment system, due to differences in pollutant types and concentrations among different water flows, a liquid flow proportioning device is required to distribute the liquid flow proportionally. This not only helps ensure that the wastewater supply rate meets the expected requirements but also facilitates precise control of the dosage of magnetic powder, coagulants, and coagulant aids based on their characteristics. Furthermore, proportional liquid flow distribution can prevent problems such as unstable floc formation or poor settling performance caused by excessive fluctuations in water quality.

[0003] Currently, multiple manufacturers have developed various models and specifications of liquid proportioning devices. However, existing designs typically rely on flow dividers to achieve proportional liquid distribution, resulting in complex structures and high manufacturing costs. The internal structure of flow dividers is relatively complex, containing numerous tiny channels and throttling orifices. If the liquid contains impurities, particles, or contaminants, these areas are prone to blockage, affecting the normal operation of the flow divider. Furthermore, due to the complexity and sensitivity of flow dividers to operating conditions, their maintenance and upkeep requirements are also high, necessitating regular inspection, cleaning, and replacement of seals and worn parts, inevitably increasing maintenance costs and downtime. Therefore, it is urgent for technical personnel to address these issues. Utility Model Content

[0004] Therefore, in view of the above-mentioned existing problems and defects, the designers of this utility model collected relevant information, conducted multiple evaluations and considerations, and carried out continuous experiments and modifications by technical personnel with many years of R&D experience in this industry, which ultimately led to the emergence of this liquid flow proportioning device.

[0005] This utility model relates to a liquid flow proportioning device, including a support frame, a liquid flow inlet cylinder, an overflow receiving cylinder, a liquid flow outlet, and a liquid blocking distribution component. The liquid flow inlet cylinder, overflow receiving cylinder, and liquid flow outlet are assembled as a single unit and supported by the support frame. The liquid flow inlet cylinder penetrates the bottom wall of the overflow receiving cylinder, and their central axes coincide, thus forming an annular overflow cavity. The liquid flow inlet cylinder has an inlet chamber, and a series of overflow notches are formed along its open end at an arc length S. The liquid flow outlet has a first guide cavity and a second guide cavity formed inside each other. The liquid blocking distribution component is vertically inserted into the annular overflow cavity, which is divided to incidentally form a first overflow distribution cavity that communicates with the first guide cavity and a second overflow distribution cavity that communicates with the second guide cavity.

[0006] As a further improvement to the technical solution disclosed in this utility model, the liquid-blocking distribution component is a combined structure, which includes a carrier, an elastic flow-blocking plate, a pressure plate, and a set of fasteners. The elastic flow-blocking plate is sandwiched between the carrier and the pressure plate, and the three are tightened by the set of fasteners. After the liquid-blocking distribution component is positioned relative to the annular overflow cavity, the outer side wall, inner side wall, and bottom wall of the elastic flow-blocking plate undergo elastic deformation due to the reverse forces from the inner side wall of the overflow receiving cylinder, the outer side wall of the liquid flow inlet cylinder, and the bottom wall of the overflow receiving cylinder, respectively.

[0007] As a further improvement to the technical solution disclosed in this utility model, the fastener assembly consists of multiple bolt assemblies arranged along the contour of the pressure plate and simultaneously penetrating the bearing member, the elastic baffle plate and the pressure plate.

[0008] As a further improvement to the technical solution disclosed in this utility model, the supporting component is a sheet metal part, which is sequentially formed by connecting an upper 90° bent section, a vertical connecting transition section, and a lower 90° bent section. The open end of the overflow receiving cylinder continues to extend and is bent at 90° to form a flat inner wall. After the liquid blocking distribution component is positioned relative to the annular overflow cavity, the upper 90° bent section and the lower 90° bent section respectively bear the reverse forces from the flat inner wall and the bottom wall of the overflow receiving cylinder.

[0009] As a further improvement to the technical solution disclosed in this utility model, the liquid-blocking distribution component also includes a manual locking assembly. The manual locking assembly is composed of a wing bolt and a nut. A clearance through-hole is formed on the upper 90° bend section to allow the wing bolt to pass freely. The nut is welded to the upper 90° bend section and is coaxial with the clearance through-hole. Rotating the wing bolt clockwise until its end contacts the flat inner wall allows the liquid-blocking distribution component to be positioned and locked; alternatively, rotating the wing bolt counterclockwise disengages its end from the flat inner wall, releasing the liquid-blocking distribution component from its lock.

[0010] As a further improvement to the technical solution disclosed in this utility model, the liquid flow proportioning device also includes a drain valve. The drain valve is inserted into the side wall of the liquid flow inlet cylinder and communicates with the liquid inlet chamber.

[0011] As a further improvement to the technical solution disclosed in this utility model, the liquid flow proportioning device also includes an inspection cover. The inspection cover is used to completely cover the opening of the overflow receiving cylinder, and it is assembled with the overflow receiving cylinder by means of a hinge.

[0012] In practical applications, the liquid flow proportioning device disclosed in this utility model can achieve at least the following beneficial technical effects, specifically:

[0013] 1) Thanks to the use of the liquid-blocking distribution component, the liquid overflowing through the overflow notch is effectively distributed proportionally to the first overflow distribution chamber and the second overflow distribution chamber. Furthermore, by adjusting the circumferential orientation of the liquid-blocking distribution component and changing the flow area, the distribution ratio of the liquid flow between the first overflow distribution chamber and the second overflow distribution chamber can be precisely controlled and adjusted. The entire flow distribution process is less prone to blockage, and the operation is convenient and quick.

[0014] 2) Through the overflow gaps, the liquid flow can overflow into the annular overflow chamber according to the expected design requirements. Furthermore, by changing the size, number, and distribution pattern of the overflow gaps, the overflow flow rate and velocity of the liquid can be precisely controlled, which is conducive to the initial adjustment of the liquid distribution ratio;

[0015] 3) The first and second guide chambers are isolated from each other, so that the liquid flow distributed by the first and second overflow distribution chambers can be guided to different channels or devices respectively, which is conducive to the independent distribution and control of the liquid flow and improves the applicability and flexibility of the equipment.

Detailed Implementation

[0031] In the description of this utility model, it should be understood that the terms "left", "right", "front", "back", "up", "down", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0032] The present invention will be further described in detail below with reference to specific embodiments. Figure 1 , Figure 2 Two perspective views of the liquid flow proportioning device disclosed in this utility model are shown respectively. It can be seen that it mainly consists of a support frame 1, a liquid flow inlet cylinder 2, an overflow receiving cylinder 3, a liquid flow outlet body 4, and a liquid blocking and distributing component 5. The support frame 1 is fixed to the ground using anchor bolts. The liquid flow inlet cylinder 2, the overflow receiving cylinder 3, and the liquid flow outlet body 4 are assembled as a single unit and are situated and fixed to the support frame 1. The liquid flow inlet cylinder 2 penetrates the bottom wall of the overflow receiving cylinder 3, and their central axes coincide, thus forming an annular overflow cavity 31. An insertion notch adapted to the outer diameter of the overflow receiving cylinder 3 is provided on the bottom wall of the overflow receiving cylinder 3 (e.g., ...). Figure 8 As shown). Figure 7 As shown, the liquid inlet cylinder 2 has an open top structure, with an inlet chamber 21, and a series of overflow notches 22 are formed along an arc length S at its open end. Figure 9 , 10 As shown, the liquid outlet body 4 is assembled and welded from multiple metal plates, and has a first guide cavity 41 and a second guide cavity 42 that are isolated from each other. The liquid blocking distribution component 5 is vertically inserted into the annular overflow cavity 31. The annular overflow cavity 31 is divided to incidentally form a first overflow distribution cavity 311 and a second overflow distribution cavity 312, which are respectively connected to the first guide cavity 41 and the second guide cavity 42.

[0033] The working principle of the liquid flow proportioning device is roughly as follows: Based on the expected proportion, the circumferential position of the liquid-blocking distribution member 5 is adjusted to form a first overflow distribution cavity 311 and a second overflow distribution cavity 312 that are mutually isolated. Liquid flows into the inlet cavity 21 and fills it. Subsequently, the liquid flows proportionally to the first overflow distribution cavity 311 and the second overflow distribution cavity 312 through the overflow notch 22. The liquid overflowing into the first overflow distribution cavity 311 flows and is discharged through the first guide cavity 41, while the liquid overflowing into the second overflow distribution cavity 312 flows and is discharged through the second guide cavity 42 (e.g., ...). Figures 3-6 (as shown in the image).

[0034] By adopting the above technical solution, on the one hand, thanks to the use of the liquid-blocking distribution component 5, the liquid overflowing through the overflow notch 22 is effectively distributed proportionally to the first overflow distribution chamber 311 and the second overflow distribution chamber 312. Furthermore, by adjusting the circumferential orientation of the liquid-blocking distribution component 5, the distribution ratio of the liquid flow between the first overflow distribution chamber 311 and the second overflow distribution chamber 312 can be precisely controlled and adjusted by changing the flow area. The entire diversion process is less prone to blockage, and the operation is convenient and quick. On the other hand, through the overflow notch 22, the liquid flow can overflow into the first overflow distribution chamber 311 and the second overflow distribution chamber 312 in a predetermined proportion according to the design requirements. Moreover, by changing the size, number, and distribution pattern of the overflow notches 22, the overflow flow rate and velocity of the liquid can be precisely controlled, facilitating the initial adjustment of the liquid distribution ratio.

[0035] Furthermore, it should be emphasized that the first guide cavity 41 and the second guide cavity 42 are isolated from each other. In this way, the liquid flow distributed by the first overflow distribution cavity 311 and the second overflow distribution cavity 312 can be guided to different channels or devices, which is conducive to the independent distribution and control of the liquid flow and improves the applicability and flexibility of the equipment, so that it can be adapted to various models of magnetic coagulation sedimentation equipment.

[0036] As described above, the liquid-blocking distribution component 5 plays a crucial role in the proportional distribution of fluid. Therefore, as... Figure 11 , Figure 12 As shown, the liquid-blocking distribution component 5 is preferably a modular structure, mainly composed of a carrier 51, a rubber baffle 52, a pressure plate 53, and a fastener assembly (not shown in the figure). The rubber baffle 52 is sandwiched between the carrier 51 and the pressure plate 52, and all three are tightened by the fastener assembly. The fastener assembly consists of multiple bolt assemblies arranged along the contour of the pressure plate 53 and passing through the carrier 51, the rubber baffle 52, and the pressure plate 53. After assembly, part of the contour of the rubber baffle 52 is exposed. Once the liquid-blocking distribution component 5 is positioned relative to the annular overflow cavity 31, the outer side wall, inner side wall, and bottom wall of the rubber baffle plate 52 undergo elastic deformation due to the opposing forces from the inner side wall of the overflow receiving cylinder 3, the outer side wall of the liquid flow inlet cylinder 2, and the bottom wall of the overflow receiving cylinder 3, respectively. The overflow gap is thus sealed, and the first overflow distribution cavity 311 and the second overflow distribution cavity 312 remain in a state of mutual isolation for a long time, which is beneficial to improving the accuracy of the proportional distribution of liquid flow.

[0037] like Figure 13 As shown, the bearing member 51 is preferably a sheet metal part, which is sequentially formed by an upper 90° bent section 511, a vertical connecting transition section 512, and a lower 90° bent section 513. Figure 8As shown, the open end of the overflow receiving cylinder 3 continues to extend and is bent at 90° to form a flat inner wall 32. After the liquid-blocking distribution component 5 is positioned relative to the annular overflow cavity 31, the upper 90° bent section 511 and the lower 90° bent section 513 respectively bear the reverse forces from the flat inner wall 32 and the bottom wall of the overflow receiving cylinder 3. In this way, on the one hand, the positioning stability of the liquid-blocking distribution component 5 is ensured, and the positional displacement caused by the liquid impact force is avoided; on the other hand, the contact between the lower 90° bent section 513 and the bottom wall of the overflow receiving cylinder 3, supplemented by the rubber baffle plate 52, lays a good foundation for further improvement of the sealing performance of the liquid-blocking distribution component 5.

[0038] It is known that, based on design common sense, the liquid-blocking distribution component 5 can adopt various design structures to achieve stable positioning and fixation relative to the overflow receiving cylinder 3. However, a technical solution with a simple design structure, easy manufacturing and implementation, and extremely convenient locking / unlocking operation is recommended here, as shown in the figure: (See figure below) Figure 11 , Figure 12 As shown, the liquid-blocking distribution member 5 is locked by means of a manual locking assembly 54. The manual locking assembly 54 is composed of a wing bolt 541 and a nut 542. The upper 90° bent section 511 has a clearance through hole 5111 formed on it to allow the wing bolt 541 to pass freely (as shown). Figure 13 (As shown in the diagram). Nut 542 is welded to the upper 90° bend section 511 and remains coaxial with the clearance through hole 5111. Rotate the wing bolt 541 clockwise until its end contacts the flat inner wall 32, the liquid blocking distribution member 5 is positioned and locked, and the mutually isolated first overflow distribution cavity 311 and second overflow distribution cavity 312 are formed. Alternatively, rotate the wing bolt 541 counterclockwise, its end disengages from the flat inner wall 32, and the liquid blocking distribution member 5 is unlocked, so that its circumferential position can be adjusted subsequently.

[0039] According to customer feedback, after prolonged operation, a large amount of contaminants inevitably accumulate inside the liquid inlet cylinder 2. This not only reduces the liquid capacity of the inlet chamber 21, but also makes cleaning through the open opening extremely time-consuming and labor-intensive, requiring workers to climb to heights. Therefore, as a further optimization of the above technical solution, such as... Figure 1 As shown, the liquid flow proportioning device is also equipped with a drain valve 6. The drain valve 6 is inserted into the side wall of the liquid flow inlet cylinder 2 and communicates with the liquid inlet chamber 21. Thus, after a period of operation, the liquid flow proportioning device periodically opens the drain valve 6 to discharge the deposited dirt, thereby increasing the soluble volume in the liquid inlet chamber 21.

[0040] Finally, it should be noted that, similarly... Figure 1As shown, the liquid flow proportioning device is also equipped with an inspection cover 7. The inspection cover 7 is used to completely cover the opening of the overflow receiving cylinder 3, and it is assembled with the overflow receiving cylinder 3 by means of a hinge 8. In this way, on the one hand, during the operation of the liquid flow proportioning device, it is convenient for the staff to check the working condition in real time and intuitively; on the other hand, the staff only needs to flip the inspection cover 7 to perform cleaning, maintenance, repair operations and circumferential position adjustment operations on the inside of the liquid flow proportioning device, without having to perform cumbersome disassembly and assembly operations.

[0041] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
