Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0022] As Figures 1 to 6 shown, the utility model provides a silicon-removing tubular membrane device, including incoming concentrated tank 1, the left side of incoming concentrated tank 1 is provided with circulating pump 2, the output end of circulating pump 2 is fixedly connected with primary filter pipe 6, the end away from circulating pump 2 of primary filter pipe 6 is fixedly connected with silicon-removing tubular membrane device 3, the middle part of silicon-removing tubular membrane device 3 is fixedly connected with membrane core pipe 14, the bottom end of membrane core pipe 14 is fixedly connected with incoming concentrated tank 1, the left side of primary filter pipe 6 is fixedly connected with cleaning pump 4, the input end of cleaning pump 4 is fixedly connected with cleaning tank 5;

[0023] Through the silicon particles in waste water separate by silicon-removing tubular membrane device 3, then the concentrated water in the center of silicon-removing tubular membrane device 3 returns to the inner cavity of incoming concentrated tank 1 through membrane core pipe 14, thereby again carries out circulating concentration separation until waste water is clean, then clean water is discharged from water production pipe 7 and flows into the subsequent system for reuse, when continuously operating for a period of time, the filtering effect of silicon-removing tubular membrane device 3 will decrease, at this time, start cleaning pump 4 to pump out the cleaning water in the inner cavity of cleaning tank 5, and transport to the inner cavities of primary filter pipe 6 and silicon-removing tubular membrane device 3, to flush primary filter pipe 6 and silicon-removing tubular membrane device 3, until silicon-removing tubular membrane device 3 restores flux, thereby realizing that complete solid-liquid separation can be carried out, the water quality is better, and the utility model structure is compact in occupation, small in area, does not need to use coagulant and flocculant, avoids the blockage of the inner cavity of silicon-removing tubular membrane device 3, and reduces the use cost.

[0024] The inner cavity of the primary filter pipe 6 is fixedly connected with a filter plate 8, and the inner cavity of the filter plate 8 is provided with a conical filter hole 9;

[0025] The setting of the conical filter hole 9 enables the water entering the inner cavity of the desiliconizing pipe type membrane assembly 3 to be filtered through the conical filter hole 9 first, and since the conical filter hole 9 is conical, the wastewater enters from a larger aperture and is discharged from a smaller aperture, so that the wastewater is compressed, thereby increasing the water pressure flow rate, and the circulating pump 2 can reach the specified speed of the flow rate of the wastewater without a large power, which is more energy-saving and environmentally friendly.

[0026] The outer surface of the primary filter pipe 6 is provided with a mounting groove 10, the inner cavity of the mounting groove 10 movably sleeves a mounting ring 12, the side of the mounting ring 12 away from the primary filter pipe 6 is fixedly connected with a rotating pipe 11, and the inner cavity of the rotating pipe 11 is fixedly connected with a cleaning rod 13;

[0027] After the silicon particles in the wastewater are preliminarily filtered through the conical filter hole 9, the larger silicon particles are retained on the surface of the filter plate 8 away from the desiliconizing pipe type membrane assembly 3, at this time, the rotating pipe 11 is rotated, the rotating pipe 11 drives the cleaning rod 13 to rotate, thereby scraping off the particles on the surface of the filter plate 8 through the cleaning rod 13, so that the silicon particles on the surface of the filter plate 8 cannot block the conical filter hole 9, and the situation that the conical filter hole 9 cannot pass water occurs, and the conical filter hole 9 can be cleaned alone when the desiliconizing pipe type membrane assembly 3 does not need to be cleaned.

[0028] The side of the desiliconizing pipe type membrane assembly 3 away from the primary filter pipe 6 is located in the water production pipe 7, and the desiliconizing pipe type membrane assembly 3 is connected with the raw material concentration tank 1 through a membrane core pipe 14;

[0029] The setting of the water production pipe 7 enables the water filtered clean by the desiliconizing pipe type membrane assembly 3 to be discharged through the water production pipe 7 and flow into the subsequent system for reuse, and the wastewater not filtered clean by the desiliconizing pipe type membrane assembly 3 enters the inner cavity of the raw material concentration tank 1 from the membrane core pipe 14 through the membrane core pipe 14.

[0030] The inner cavity of the cleaning tank 5 is filled with cleaning water, and the inner cavity of the cleaning tank 5 is communicated with the inner cavity of the desiliconizing pipe type membrane assembly 3 through the cleaning pump 4, the primary filter pipe 6 and the rotating pipe 11;

[0031] When the desiliconizing pipe type membrane assembly 3 is used for a long time, the cleaning water in the inner cavity of the cleaning tank 5 can be pumped out from the inner cavity of the cleaning tank 5 by the cleaning pump 4 and delivered to the inner cavity of the desiliconizing pipe type membrane assembly 3, so that the interior of the desiliconizing pipe type membrane assembly 3 is cleaned, and the chemical cleaning is regularly performed during the long-term operation to restore a better flux, so that the high-quality water production is obtained through the continuous use.

[0032] The conical filter hole 9 is conical, the larger hole of the conical filter hole 9 is located on the side of the filter plate 8 close to the cleaning rod 13, and the smaller hole of the conical filter hole 9 is located on the side of the filter plate 8 close to the silicon-removing tubular membrane device 3.

[0033] The water pressure and flow rate of the wastewater are increased through the compression of the conical filter hole 9, so that the flow rate of the wastewater can be improved, thereby reducing the power of the circulating pump 2.

[0034] The cleaning rod 13 is attached to the surface of the filter plate 8.

[0035] The cleaning rod 13 is attached to the surface of the filter plate 8, so that the installation ring 12 is rotated along the installation groove 10 by rotating the rotating pipe 11, thereby driving the cleaning rod 13 to rotate, and the particles accumulated on the surface of the filter plate 8 are removed by the cleaning rod 13.

[0036] The working principle and use process of the utility model are as follows: the incoming concentrated tank 1 receives the wastewater containing silicon particles, when the wastewater in the inner cavity of the incoming concentrated tank 1 reaches a high liquid level, the circulating pump 2 is automatically started to run and transports the wastewater in the inner cavity of the incoming concentrated tank 1 to the silicon-removing tubular membrane device 3, the wastewater first contacts the filter plate 8, and is initially filtered by the conical filter hole 9, and the shape of the conical filter hole 9 makes the wastewater enter the smaller hole from the larger hole when passing through the conical filter hole 9, thereby increasing the flow rate;

[0037] Then the silicon particles in the wastewater are separated by the silicon-removing tubular membrane device 3, the flow rate of the wastewater in the silicon-removing tubular membrane device 3 reaches 4 m / s, the working pressure is not more than 3 kg, the clean water passes through the 0.05 micron membrane to reach the water production pipe 7 under the condition that the working pressure is not more than 3 kg, then the concentrated water in the center of the silicon-removing tubular membrane device 3 returns to the inner cavity of the incoming concentrated tank 1 through the membrane core pipe 14, thereby performing the cycle concentration and separation again until the wastewater is clean, then the clean water is discharged from the water production pipe 7 and flows into the subsequent system for reuse, after continuous operation for a period of time, the filtering effect of the silicon-removing tubular membrane device 3 decreases, at this time, the cleaning pump 4 is started to pump the cleaning water in the inner cavity of the cleaning tank 5, and the cleaning water is transported to the inner cavities of the preliminary filtration pipe 6 and the silicon-removing tubular membrane device 3, so as to flush the preliminary filtration pipe 6 and the silicon-removing tubular membrane device 3, until the silicon-removing tubular membrane device 3 restores the flux.
