Description

Technical Field

[0001] This utility model relates to the field of water treatment technology, and in particular to an interlocking coagulation reaction grid. Background Technology

[0002] In the field of water treatment, the coagulation stage plays a crucial role in removing suspended and colloidal substances from water. To improve flocculation efficiency, numerous technologies have been developed and applied. For example, "An Adjustable Gas-Liquid Multiphase Vortex Coagulation Reaction Grid (ZL202222203906)" achieves gas-liquid multiphase vortex coagulation reaction through specific structural design to promote flocculation. However, this technology has some shortcomings. Its structural stability needs improvement; in practical applications, it is prone to structural deformation in complex water flow environments, affecting the continuity and stability of its flocculation effect. Furthermore, the porosity adjustment method of its grid is relatively complex, limiting its flexibility and making it difficult to quickly and conveniently change the porosity according to different water qualities and treatment requirements, resulting in insufficient adaptability. In addition, the material usage of this structure is not optimized, leading to a large overall weight, which not only increases installation difficulty but also raises transportation and installation costs.

[0003] In addition to the technologies mentioned above, there is also the small-aperture grid flocculation reaction process. After the secondary sedimentation tank effluent containing flocculant is thoroughly mixed in a mixer, it enters the small-aperture grid flocculation tank for flocculation. Suspended solids and phosphorus in the incoming water react to form flocs, which are then removed through clarification in a sedimentation tank. This process utilizes the inertial effect generated by water flowing through the small-aperture grid plate, creating a high proportion and high intensity of micro-vortex centrifugal inertial effect behind the apertures, thus solving the problem of fine mass transfer of coagulant hydrolysis products. However, the grid structure of this process also suffers from poor stability. During long-term use, the grid is easily damaged by factors such as water flow impact and floc adhesion, requiring frequent maintenance.

[0004] The hydrocyclone grid flocculation device uses a special structural design to create eddies and shear forces, promoting the collision and agglomeration of suspended particles in water and improving flocculation efficiency. Its inlet structure design creates a strong rotating eddy current in the water flow, enhancing shear force and the proportion of micro-vortices, thus promoting the collision and agglomeration of tiny particles. However, this device has a relatively complex structure and high manufacturing cost. Furthermore, its porosity is based on a specific honeycomb grid panel and other structural designs, making it difficult to adjust flexibly and meet diverse water treatment needs.

[0005] In summary, existing water treatment flocculation technologies have varying degrees of shortcomings in terms of stability, porosity flexibility, material utilization, and portability, and a new technical solution is urgently needed to address these issues. Summary of the Invention

[0006] This utility model's interlocking coagulation reaction grid is mainly composed of multiple crisscrossing pipes. These pipes are all hollow tubes with a uniform cross-sectional shape. At the intersection of the longitudinal and transverse pipes, holes are machined on the transverse pipes to match the outer dimensions of the longitudinal pipes. The longitudinal pipes are precisely inserted into these holes, thus forming a stable interlocking structure. Numerous such interlocking structures are arranged in an alternating pattern to form a mesh structure. In actual flocculation tanks, when the water flow velocity changes significantly or the water flow direction changes irregularly, traditional grids may experience localized loosening or even overall structural deformation. However, this flocculation grid, due to its stable interlocking structure, can withstand greater water flow impact forces, continuously and stably increasing water flow turbulence and promoting flocculation. This flocculation grid is specifically designed for flocculation tanks in the coagulation stage of water treatment. Its working principle is to effectively increase the degree of water flow turbulence through the mesh structure formed by the interlocking structure, thereby accelerating the flocculation process of colloids.

[0007] Based on the above concept, the technical solution adopted by this utility model to solve the aforementioned problems is as follows:

[0008] A type of interlocking concrete reaction grid, characterized in that it includes: a mesh body 3 and a frame 5, wherein the mesh body 3 is formed by multiple sets of horizontal tubes 1 and vertical tubes 2 interlocked vertically, the horizontal tubes 1 are provided with through holes 4 at intervals along their length direction, the size of the through holes 4 is matched with the outer diameter of the vertical tubes 2, and the vertical tubes 2 are inserted through the through holes 4 of the horizontal tubes 1 to form a crisscrossing grid structure.

[0009] The frame 5 surrounds the edge of the mesh body 3. The frame 5 is formed by connecting the ends of the same type of pipe as the horizontal pipe 1 or the vertical pipe 2. The horizontal pipe 1 and the vertical pipe 2 are both hollow pipes. The porosity of the mesh structure can be flexibly adjusted by increasing or decreasing the number of horizontal pipe 1 or vertical pipe 2, or by adjusting the spacing between the horizontal pipe 1.

[0010] The cross-sectional shape of the transverse tube 1 and the longitudinal tube 2 is at least one of square, circular or polygonal.

[0011] The transverse tube 1 and the longitudinal tube 2 are made of metallic or non-metallic materials; the metallic materials include at least one of stainless steel, aluminum alloy, and galvanized steel; the non-metallic materials include at least one of polyvinyl chloride (PVC), polypropylene (PP), fiberglass, and polymethyl methacrylate (PMMA).

[0012] The through hole 4 is formed by laser cutting, stamping or drilling, and the inner wall of the through hole 4 forms an interference fit or clearance fit with the outer wall of the longitudinal tube 2.

[0013] The frame 5 is fixed to the mesh body 3 by means of plugging, welding or snap-fit ​​connection.

[0014] The hollowness of the transverse tube 1 and the longitudinal tube 2 is 50%-90%, and the tube wall thickness is 1-5mm.

[0015] Compared with the prior art, the present invention has the following advantages:

[0016] 1. High Stability: The interlocking structure of this flocculation mesh is the key guarantee of its stability. The longitudinal pipes are tightly inserted into the holes of the transverse pipes, and this connection method gives the mesh strong resistance to deformation in all directions. Compared with some traditional mesh structures, this new mesh can better maintain its shape and structural integrity when facing complex water flow impacts, ensuring stable flocculation performance.

[0017] 2. Flexible Porosity: A significant advantage of this invention lies in its highly flexible porosity. Since the entire grid is composed of multiple independent pipes interlocked together, the porosity can be easily altered according to actual water treatment needs by adjusting the number, spacing, and interlocking method of the pipes. For example, when treating high-turbidity raw water, the number of pipes can be reduced to increase porosity, allowing water to flow through the grid more quickly while ensuring sufficient turbulence to promote the flocculation of large particles. Conversely, when treating low-turbidity water with high quality requirements, the number of pipes can be increased to decrease porosity, ensuring sufficient turbulence for colloidal and other microparticles, thus improving flocculation. This flexible porosity adjustment method makes this flocculation grid widely applicable to various water treatment scenarios with different water qualities and treatment requirements, greatly improving its applicability and versatility.

[0018] 3. Material Saving and Lightweight: The pipes in this flocculation grid feature a hollow design, which offers numerous advantages. First, compared to solid pipes, hollow pipes significantly reduce material usage while ensuring structural strength meets performance requirements. For example, with common metal pipes, the hollow design reduces material consumption by approximately 30%-50%. This not only lowers production costs but also significantly reduces the overall weight of the grid. Lighter grids are easier to install and transport, saving considerable manpower, resources, and time.

[0019] 4. A wide range of pipe materials are available, including but not limited to metals and plastics. Metal pipes offer high strength and corrosion resistance, making them suitable for water treatment scenarios with high structural strength requirements and complex water quality. Plastic pipes, on the other hand, are lightweight, low-cost, and corrosion-resistant, offering significant advantages in projects where weight and cost are critical. Users can flexibly choose the appropriate pipe material based on their actual usage environment and needs, further optimizing the performance and cost of the flocculation mesh.
