Description

Technical Field

[0001] This utility model belongs to the field of water treatment, and in particular relates to a honeycomb-shaped guide plate pretreatment dilution device. Background Technology

[0002] In the field of fluid handling in industrial production, pretreatment dilution devices are widely used in wastewater treatment, chemical reactions, food processing, and other scenarios as key equipment for achieving uniform mixing of media of different concentrations. Among them, honeycomb guide plates are commonly used for fluid guidance and preliminary mixing in the pretreatment stage due to their characteristics of uniform flow field distribution, low fluid resistance, and strong structural stability.

[0003] In existing technologies, honeycomb baffles typically employ a hexagonal cavity structure with equal diameter. The regular honeycomb cells guide the fluid flow, allowing the original fluid and diluent to mix in laminar or weakly turbulent flow within the cavities. However, this traditional structure has significant limitations in practical applications: the uniform fluid velocity distribution within the equal-diameter honeycomb cavities lacks effective shear force and turbulent excitation, resulting in only preliminary macroscopic mixing of the original fluid and diluent. Microscopic mixing uniformity is insufficient, especially in the treatment of high-concentration fluids, easily leading to localized concentration deviations that affect the stability of subsequent processing steps. Utility Model Content

[0004] The purpose of this invention is to address the aforementioned technical problems by providing a honeycomb-shaped guide plate pretreatment dilution device. Through a design that decreases in aperture along the flow direction and is combined with spiral grooves on the inner wall, it can overcome the limitations of uniform flow velocity in traditional equal-diameter cavities, enhance fluid shear force and turbulence excitation, improve the microscopic mixing uniformity of the original fluid and the dilution medium, reduce local concentration deviations, and ensure the stability of subsequent processes.

[0005] In view of this, the present invention provides a honeycomb-shaped guide plate pretreatment dilution device, comprising:

[0006] The cylindrical body has openings at both ends;

[0007] A flow guiding mechanism, located within the inner cavity of the cylinder, is used for guiding and treating the fluid. The flow guiding mechanism includes:

[0008] A column is provided in the inner cavity of the cylinder, and multiple equally spaced honeycomb guide holes are provided on the column, and the diameter of the multiple honeycomb guide holes decreases from the inlet end to the outlet end along the flow direction.

[0009] Spiral grooves are formed on the inner wall of the honeycomb guide holes. When the fluid flows from the large hole to the small hole, the flow velocity gradually increases and a spiral vortex is formed. Combined with the throttling effect generated by the change in hole size gradient, the shearing and mixing of fluids of different concentration layers is enhanced.

[0010] In this technical solution, by using a design that decreases in orifice diameter along the flow direction in conjunction with a spiral groove on the inner wall, the limitation of uniform flow velocity in traditional equal-diameter cavities can be overcome, the fluid shear force and turbulence excitation can be enhanced, the microscopic mixing uniformity of the original fluid and the dilution medium can be improved, local concentration deviations can be reduced, and the stability of subsequent processes can be ensured.

[0011] Furthermore, the honeycomb flow guide holes are regular hexagonal.

[0012] In this technical solution, the hexagonal honeycomb guide holes can optimize the fluid diversion and guidance effect, enhance the structural stability, and make the fluid more likely to form orderly turbulence under the action of gradient aperture and spiral groove, thereby further improving the mixing uniformity.

[0013] Furthermore, the diameter of the honeycomb guide hole at the inlet end of the column is 10mm, and the diameter decreases by 1mm every 5cm segment along the flow direction until it reaches 4mm at the outlet end.

[0014] In this technical solution, the flow rate increase rhythm can be precisely controlled through a specific aperture gradient design, which strengthens the synergistic effect of helical vortex and throttling effect, effectively solves the problem of insufficient mixing in traditional equal-diameter structures, and improves the overall pretreatment effect.

[0015] Furthermore, a fixing ring is provided at both ends of the cylinder opening, and the fixing ring overlaps the end face of the column and does not contact the honeycomb guide hole. A fixing bolt is rotatably passed through the fixing ring, and the fixing bolt is threaded to the end face surface of the cylinder.

[0016] In this technical solution, the combination of fixing ring and fixing bolt not only achieves a stable connection between the column and the cylinder, but also avoids interference with the fluid flow of the honeycomb guide holes. At the same time, it facilitates the disassembly and maintenance of the device and ensures the stable operation of the guide mixing structure.

[0017] Furthermore, a circular groove is provided on the fixing bolt corresponding to the fixing bolt, the head of the fixing bolt is placed in the circular groove, and the thickness of the fixing bolt head is less than the depth of the circular groove.

[0018] In this technical solution, by fixing the head of the bolt inside the circular groove, it is possible to prevent the head from protruding and causing fluid resistance or external impact damage, keep the end face of the device flat, and avoid interfering with the flow field stability of the fluid inlet and outlet.

[0019] Furthermore, silicone pads are fixedly connected to the open end faces at both ends of the cylinder and the outer side of the column, and the silicone pads are elastic.

[0020] In this technical solution, the elastic setting of the silicone pad enhances the sealing of the connection between the cylinder and the column, prevents fluid leakage, buffers the impact force during installation, reduces component wear, and improves the durability of the device.

[0021] The beneficial effects of this utility model are:

[0022] 1. This utility model, through a design that decreases in orifice diameter along the flow direction and combined with spiral grooves on the inner wall, can overcome the limitations of uniform flow velocity in traditional equal-diameter cavities, enhance fluid shear force and turbulent excitation, improve the microscopic mixing uniformity of the original fluid and dilution medium, reduce local concentration deviations, and ensure the stability of subsequent processes.

[0023] 2. This utility model achieves a stable connection between the column and the cylinder through the combination of the fixing ring and the fixing bolt, while avoiding interference with the fluid flow of the honeycomb guide holes. At the same time, it facilitates the disassembly and maintenance of the device and ensures the stable operation of the guide mixing structure. Attached Figure Description

[0033] like Figure 1-2 As shown, this utility model provides a honeycomb-shaped guide plate pretreatment dilution device, comprising:

[0034] Cylinder 1, both ends of cylinder 1 are open;

[0035] A flow guiding mechanism, located within the inner cavity of the cylinder 1, is used for fluid flow guidance and treatment. The flow guiding mechanism includes:

[0036] A column 2 is located inside the cavity of the cylinder 1. The column 2 has a plurality of equally spaced honeycomb guide holes 21, and the diameter of the plurality of honeycomb guide holes 21 decreases from the inlet end to the outlet end along the flow direction.

[0037] The spiral groove 22 is formed on the inner wall of the honeycomb guide hole 21. When the fluid flows from the large hole to the small hole, the flow velocity gradually increases and a spiral vortex is formed. Combined with the throttling effect generated by the change of hole diameter, it enhances the shear mixing of fluids of different concentration layers.

[0038] With the honeycomb guide holes 21 having a decreasing diameter along the flow direction, when the fluid enters the cylinder 1, it first flows through the honeycomb guide holes 21 on the column 2. During the flow, the fluid will naturally accelerate due to the space contraction. At the same time, the spiral grooves 22 on the inner wall of the holes guide the fluid to form a spiral vortex. The accelerated fluid generates a continuous shear force under the drive of the vortex, causing the original fluid and the dilution medium to be continuously torn and mixed during the flow. This breaks the limitation of the fluid flow rate being uniform and only being able to be initially mixed in the traditional equal-diameter cavity, achieving full mixing, reducing the local accumulation of high-concentration fluid, and providing a stable fluid state for subsequent treatment.

[0039] The honeycomb guide hole 21 is a regular hexagon.

[0040] Compared to other shapes, the hexagonal honeycomb guide holes 21 can more evenly divert and guide the fluid entering the cylinder 1, allowing the fluid to form a regular flow pattern before entering the gradient-changing cavity. At the same time, the hexagonal structure gives the guide mechanism stronger overall stability, making it less prone to deformation under fluid pressure. This ensures that the aperture gradient change and the design of the spiral groove 22 can function stably and continuously, allowing the fluid to maintain an orderly turbulent state during the flow process. This further improves the mixing uniformity of the original fluid and the dilution medium, alleviating the problem of insufficient mixing in traditional structures.

[0041] The diameter of the honeycomb guide hole 21 at the inlet end of the column 2 is 10mm, and the diameter decreases by 1mm every 5cm along the flow direction until it reaches 4mm at the outlet end.

[0042] By setting specific aperture gradient variations, the fluid velocity can be made to increase in a regular manner along the flow direction, avoiding flow field turbulence caused by sudden velocity changes. This orderly velocity variation, in conjunction with the vortex formed by the spiral groove 22, can gradually enhance the shearing effect and throttling effect between fluids, allowing the original fluid and dilution medium to be continuously separated and mixed during the flow process. This more thoroughly solves the problem of low mixing efficiency caused by the stable flow velocity and insufficient turbulence in traditional equal-diameter honeycomb cavities, and comprehensively improves the pretreatment and dilution effect of the device on the fluid. Example

[0043] like Figure 2-3 As shown, a fixing ring 3 is provided at both ends of the opening of the cylinder 1, and the fixing ring 3 overlaps the end face of the column 2 and does not contact the honeycomb guide hole 21. A fixing bolt 32 is rotatably passed through the fixing ring 3, and the fixing bolt 32 is threadedly connected to the end face surface of the cylinder 1.

[0044] The fixing ring 3 overlaps with the end face of the column 2 without contacting the honeycomb guide hole 21. This achieves a stable connection between the column 2 and the cylinder 1 through the fixing bolt 32, while avoiding interference with the fluid flow within the guide hole. This ensures that the gradient aperture and spiral groove 22 design can continuously and stably perform their mixing function. Simultaneously, the detachable fixing bolt 32 design facilitates the installation and removal of the column 2, solving the problem of difficult maintenance and cleaning of the guide mechanism after it is fixed in traditional devices. This ensures the unobstructed flow of the honeycomb guide hole 21 during long-term use and maintains stable mixing efficiency.

[0045] A circular groove 31 is provided on the fixing bolt 32 corresponding to the fixing bolt 32, the head of the fixing bolt 32 is placed in the circular groove 31, and the thickness of the head of the fixing bolt 32 is less than the depth of the circular groove 31.

[0046] By placing the head of the fixing bolt 32 inside the circular groove 31 with a thickness less than the groove depth, the head of the fixing bolt 32 can be prevented from protruding from the surface of the fixing ring 3, thus preventing it from obstructing the flow of fluid at both ends of the cylinder 1 or causing local turbulence. This ensures that the flow pattern of the fluid is stable before entering the honeycomb guide hole 21. In addition, it can reduce the collision interference of the external environment on the fixing bolt 32, prevent it from loosening, and ensure the connection stability between the column 2 and the cylinder 1. This maintains the structural accuracy of the guide mechanism during operation and ensures that the mixing uniformity is not affected by structural loosening.

[0047] Silicone pads 4 are fixedly connected to the open end faces of both ends of the cylinder 1 and the outer side of the column 2, and the silicone pads 4 are elastic.

[0048] The elastic silicone pad 4 between the cylinder 1 and the column 2 can fill the tiny gaps at the connection surfaces, enhance the sealing of the device, prevent fluid leakage from the gaps during pretreatment, and avoid concentration deviations caused by medium loss. On the other hand, the elasticity of the silicone pad 4 can buffer the vibrations generated by fluid flow, reduce the rigid collision wear between the column 2 and the cylinder 1, extend the service life of the device, and prevent the displacement of the guide hole position caused by vibration, ensuring the continued effectiveness of the synergistic effect of the gradient aperture and the spiral groove 22 design.

[0049] The embodiments of this application have been described above with reference to the accompanying drawings. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. This application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of this application without departing from the spirit and scope of the claims, and all of these forms are within the protection scope of this application.
