Specific embodiments

[0028] To make the above features and advantages of the present invention more understandable, specific embodiments are given below in conjunction with the accompanying drawings and described in detail as follows, but the present invention is not limited thereto.

[0029] Refer to Figures 1 - 5 .

[0030] In a preferred embodiment of the present invention: A flocculation reaction precipitation device includes an outer cylinder. A reaction coiled pipe assembly for flocculation reaction is provided at the bottom of the outer cylinder. A filtering assembly is provided at the upper part of the outer cylinder to filter the flocs formed by the flocculation reaction. An outlet assembly is provided at the top of the outer cylinder. The reaction coiled pipe assembly includes a first reaction coiled pipe, a second reaction coiled pipe and a third reaction coiled pipe which are arranged in sequence from inside to outside. A sewage pipe assembly is provided below the reaction coiled pipe assembly so that the sediment in the device is discharged from the sewage pipe. The water body containing the flocculant passes through the first reaction coiled pipe, the third reaction coiled pipe and the second reaction coiled pipe in sequence, and is subjected to centrifugal force in the first reaction coiled pipe and the third reaction coiled pipe. The impurities are enriched and collided on both sides of the channel to generate flocculent sediment, and then naturally settle after entering the second reaction coiled pipe. The preliminarily clarified water body is filtered by the filtering assembly and then output by the outlet assembly.

[0031] In this embodiment, the first reaction coil includes a first inner cylinder disposed within the outer cylinder. A first cylinder cover is provided at the top of the first inner cylinder to prevent water with impurities from contaminating the purified water. A float check valve is provided on the first cylinder cover. By pulling open the float check valve, the float check valve includes a cylindrical shell disposed at the water inlet. An inlet hole is provided at the upper end of the shell. A float for controlling the opening and closing of the inlet hole is disposed within the shell. The float uses the water in the first reaction coil to control its lifting and lowering. When the water in the first inner cylinder is discharged through the sewage discharge assembly, the float drops, and the water in the outer cylinder enters the first reaction coil to clean it. A sealing ring is provided on the inlet hole. A counterweight pipe is provided at the bottom of the float. A limiting rod for preventing the float from falling is provided on the lower side of the shell, avoiding the inconvenience of manual cleaning. A sludge discharge cylinder penetrates through the first inner cylinder. A sludge discharge hopper is provided at the top of the sludge discharge cylinder. Multiple support rods are provided at the bottom of the sludge discharge hopper. The other ends of the support rods are fixedly connected to the first cylinder cover to increase the stability of the sludge discharge hopper and prevent it from being damaged under the impact of water flow, enabling the sediment in the water above the reaction coil assembly to smoothly pass through the sludge discharge hopper and the sludge discharge cylinder into the bottom of the first reaction coil. An inlet pipe is provided at the upper part of the first inner cylinder. An inclined port is provided at the water outlet of the inlet pipe to control the water flow direction. A first outlet pipe communicating with the third reaction coil is provided at the lower part of the first inner cylinder. A check valve is provided within the first outlet pipe to prevent the backflow of water. The first outlet pipe passes through the second reaction coil. A spiral plate is vertically disposed between the first inner cylinder and the sludge discharge cylinder. The spiral angle of the spiral plate is 6-8°. A spiral channel communicating the inlet pipe and the first outlet pipe is formed on the spiral plate, such that the impurities in the water flowing through the spiral pipe adhere to both sides of the channel due to centrifugal force, increasing the probability of their collision. Multiple shock wave baffle assemblies penetrate through the spiral channel from top to bottom.

[0032] In this embodiment, the number of the shock wave baffle assemblies is 4, which are evenly distributed in the circumferential direction between the first inner cylinder and the sludge discharge cylinder and are at the same distance from the first inner cylinder and the sludge discharge cylinder, such that the water flow rates on both sides are the same. The shock wave baffle assembly includes an A plate and a B plate that are perpendicular to each other. Both the A plate and the B plate are perpendicular to the ground. The angular bisector direction of the A plate and the B plate is the same as the water flow direction within the spiral channel. When the water flow passes through the shock wave baffle assembly, the size of the water flow channel changes from large to small, and the water flow is divided into two streams. After passing through the shock wave baffle, due to the sudden change in the shape and size of the water flow channel, the two streams of water flow towards the center and collide, causing the impurities to adhere to each other and generate flocculation.

[0033] In this embodiment, the third reaction coil includes a second inner cylinder disposed within the outer cylinder. The second reaction coil is located between the second inner cylinder and the first inner cylinder, and the third reaction coil is located between the second inner cylinder and the outer cylinder. A communication port for connecting the second reaction coil and the third reaction coil is provided at the bottom of the second inner cylinder. A flow guide plate is provided at the communication port to control the water flow direction and prevent the flocs from being broken by the impact of the water flow. The third reaction coil includes an upper and lower swirl structure disposed between the second inner cylinder and the outer cylinder. When the water flow passes through the upper and lower swirl structure, the impurities in the water flow are subjected to centrifugal force, accumulate and collide on both sides of the water flow channel, generating floc precipitation. A second cylinder cover is provided on the upper and lower swirl structure to prevent the water polluted with impurities from contaminating the purified water body.

[0034] In this embodiment, in order to increase the travel of the water flow, the upper and lower swirl structure includes a plurality of vertically arranged partitions. The number of partitions is an even number. In order to enable the flocs to be subjected to sufficient resistance during the process of flowing with the water flow and convert the stable flow into turbulent flow, multiple layers of grids are horizontally arranged between two partitions. The grid size of the grids is much larger than the size of the precipitation. Notches are provided above or below the partitions. The partitions with notches above and the partitions with notches below are arranged at intervals, so that the water flow flows along an up-and-down spiral path under the action of the partitions, causing the water flow to continuously change its direction in the path and always be in a turbulent state, and increasing its reaction travel. The first water outlet pipe and the communication port are arranged on both sides of the partition with a notch at the lower end, so as to maximize the reaction travel. A blocking plate is provided at the notch of this partition.

[0035] In this embodiment, a water flow obstruction mechanism is provided in the second reaction coil. The water flow obstruction mechanism includes a plurality of reinforcing plates provided on the outer side of the first inner cylinder and the inner side of the second inner cylinder to increase the structural strength of the first cylinder and the second cylinder and slightly increase the water flow resistance. The reinforcing plates on the outer side of the first cylinder correspond to the reinforcing plates on the inner side of the second cylinder one by one. Reinforcing square pipes are provided on the reinforcing plates to further increase the structural strength of the first cylinder and the second cylinder and slightly increase the water flow resistance. However, the water flow resistance will not be too large to cause the flocs to break. When the water flow passes through the second reaction coil, since there is no narrow water flow channel and large resistance in the second reaction coil, the water flow velocity gradually slows down, and the floc precipitation gradually sinks, and the water body is initially clarified.

[0036] In this embodiment, a plurality of ventilation pipes are provided on both the first cylinder cover and the second cylinder cover. The ends of the ventilation pipes penetrate through the outer cylinder to discharge the gas generated during impurity flocculation.

[0037] In this embodiment, the filtering component includes a support bracket arranged at the top of the reaction coil assembly. A plurality of inclined thin tubes are arranged on the support bracket. The thin tubes fill the upper part of the outer cylinder, so that all the output water bodies need to pass through the screen formed by the thin tubes. And because the length dimension of the thin tubes is much larger than the diameter dimension, even if the fine impurities in the water body enter the thin tubes, they will constantly be blocked by the side walls and gradually sink, so that the impurities are removed when the water flow passes through the thin tubes. The thin tubes are bundled by nylon ropes to ensure their stability and prevent loosening.

[0038] In this embodiment, the water outlet component includes a water outlet tank arranged at the top of the outer cylinder. Sawteeth are arranged at the top of the water outlet tank. Since the notch part of the sawteeth is smaller at the bottom and larger at the top, it can distribute the water discharged from the device to ensure the constant flow rate at each water outlet pipe. The cleanest water at the top passes through the sawteeth and enters the water outlet tank. A main water outlet pipe is arranged at the water outlet of the water outlet tank, and a connecting flange is arranged at the pipe orifice of the main water outlet pipe for quick disassembly and assembly.

[0039] In this embodiment, the sewage discharge pipe component includes a first sewage discharge ring pipe arranged below the first reaction coil, a second sewage discharge ring pipe arranged below the second reaction coil, and a third sewage discharge ring pipe arranged below the third reaction coil. Through holes for sucking flocculants are arranged on all three sewage discharge ring pipes, and sewage discharge pipes leading to the outside of the outer cylinder are arranged on all three sewage discharge ring pipes. Notch parts for avoiding the sewage discharge pipes are arranged on both the second sewage discharge ring pipe and the third sewage discharge pipe. After using for a period of time, a certain amount of flocculant precipitate accumulates in the device. When the valves of each sewage discharge pipe are opened, the water bodies in the three reaction coils enter the sewage discharge ring pipes through the through holes, and the flocculent substances deposited at the bottom of the water bodies are torn into small pieces and enter the sewage discharge ring pipes along with the water flow. When the water in the first reaction coil gradually drains out, the float in the float check valve drops, and the water in the outer cylinder enters the first reaction coil to clean it, so as to realize the impurity treatment after long-term use, avoid disassembling the whole machine, and reduce the workload of cleaning.

[0040] The working principle of a flocculation reaction precipitation device based on the above embodiment includes the following steps:

[0041] 1) After mixing the water body collected from the natural environment with a flocculant, it is injected into the flocculation reaction precipitation device from the water inlet pipe;

[0042] 2) The water body and the flocculant enter the spiral channel together. Under the centrifugal action of the spiral channel, impurities gradually accumulate on both sides of the spiral channel, collide and flocculate with each other, and the flocculation reaction is further intensified under the action of the shock baffle assembly;

[0043] 3) The water body with flocs enters the up-and-down swirl structure from the first water outlet pipe, and continuously moves up and down under the action of the partition plate. The large flocs gradually settle into the sewage discharge pipe component under the action of the grille and their own weight;

[0044] 4) The preliminarily precipitated water body enters the second reaction coil pipe through the communication port, the water level slowly rises, overflows the thin pipe, and reaches the water outlet tank. The fine flocculants gradually settle due to their own weight and the action of the inclined thin pipe, and enter the sewage pipe assembly through the sludge discharge hopper;

[0045] 5) The clean water body enters the water outlet tank through the sawteeth on the water outlet tank and is output through the main water outlet pipe;

[0046] 6) After being used for a period of time, open the floating ball one-way valve and the sewage pipe outlet, and the clean water body automatically flows down to wash the internal structures of the flocculation reaction precipitation device.

[0047] The above are only the preferred embodiments of the present invention. For those of ordinary skill in the art, according to the teachings of the present invention, designing different forms of flocculation reaction precipitation devices and their working principles does not require creative labor. Without departing from the principles and spirit of the present invention, all equal changes, modifications, substitutions, and variations made within the scope of the patent application of the present invention shall fall within the scope covered by the present invention.
