[0002] Flocculation treatment is an important link in water purification treatment process, and its effect directly affects the quality of purified water in water plant. At present, most of the water plants in urban and rural cities use large-scale water purification equipment integrating flocculation, sedimentation and filtration. Each vertical shaft of the grid flocculation tank is equipped with several layers of grids or bars. Since the grids or bars in each vertical shaft are independently fixed and installed, this greatly increases the construction difficulty and workload. Moreover, after a period of use, the grid plates may be dirty and clogged or damaged, which requires manual cleaning or replacement inside the vertical shaft, greatly increasing the work difficulty. Due to the structural limitations of the grid part of the large-scale water purification equipment, the number of grids cannot be adjusted. When the water quality or raw water volume changes significantly, the working efficiency cannot reach the optimal state under different working conditions, which may cause certain difficulties in the operation of the water plant, especially for the water plant with large water consumption. SUMMARY

[0003] The utility model aims at solving the above-mentioned problems and provides an assembled fan-shaped grid flocculation monomer device. The device has compact structure, small footprint, good flocculation effect, and can be applied to centralized small-sized water treatment equipment to ensure the safety of drinking water in small-scale towns or communities. When the grid plate is dirty or damaged, the fan-shaped grid plate can be disassembled from the grid well for maintenance and cleaning, without the need to enter the narrow vertical shaft to maintain the grid or bar. According to the actual water quality and water volume of the raw water to be treated, the number of fan-shaped grid plates can be increased or decreased to make the device achieve optimal working efficiency.

[0004] In order to achieve the above object, the utility model provides a kind of assembled fan-shaped grid flocculation monomer device, it is characterized in that: the assembled fan-shaped grid flocculation monomer device includes cylindrical frame, base, top plate, outlet pipe, blow-off pipe, vertical partition, limit plate, support round pipe, grid plate one, grid plate two, grid plate three, pressing plate, rubber plate, baffle, bolt, nut, flat washer, spring washer.The base is welded with cylindrical frame, top plate, the outlet pipe and blow-off pipe are arranged in device cylindrical frame lower part respectively, the limit plate is evenly welded in the inside of cylindrical frame to ensure that equal division tube inside flocculation work area is divided, the upper and lower ends of the support round pipe are welded with baffle respectively to block, the grid plate is fixed by bolt nut washer bolt connection with rubber plate, pressing plate and forms grid assembly, the grid assembly passes through support round pipe from grid plate hole and is welded on support round pipe respectively to form three flocculation area grid assembly, after limit plate welding is completed, the vertical wallboard is inserted into the inside of cylindrical frame and is fixed vertical wallboard with limit plate, three flocculation area grid assembly is inserted into the three flocculation work area formed respectively, wherein rubber plate is closely attached to the inner wall of cylindrical frame to fix the grid assembly of three flocculation areas.

[0005] Further, the layer number of the grid plate in the first flocculation area and the second flocculation area is 6-11 layers, and the layer number of the grid plate in the third flocculation area is 6 layers.

[0006] Further, the distance between each adjacent grid plate is 0.2 m.

[0008] I. The utility model adopts concentric circle fan-shaped grid plate as the flocculation grid plate inside the grid well, compared with the square grid plate in the traditional water plant flocculation tank, the turbulent flocculation channel formed by the radial vortex hole greatly enhances the disturbance of water flow through the hole, forms a large number of micro-vortexes, and improves the hydraulic flocculation effect. At the same time, through the vertical direction multi-level grid arrangement, the overall flocculation area is increased, the flocculation effect is guaranteed, and the device volume and actual land area are reduced.

[0009] II. Compared with the grid area cleaning and maintenance of the flocculation tank of the existing large water purification equipment, the utility model is convenient for disassembling the fan-shaped grid plate of the grid well, thoroughly cleaning, and timely replacing the seriously damaged grid to guarantee the stable and reliable operation of the device.

[0010] III. For the actual working condition that the water quality and raw water quantity fluctuate greatly in water treatment engineering, the utility model can reasonably adjust the flocculation area by increasing or decreasing the number of fan-shaped grid plates, so as to achieve the best flocculation effect and optimize the working efficiency of the device.
