Description

Technical Field

[0001] This invention belongs to the field of sodium silicate production technology, specifically a continuous sodium silicate production filtration device. Background Technology

[0002] Sodium silicate, commonly known as sodium silicate, is an inorganic substance. Its aqueous solution is commonly known as water glass, which is a mineral binder. Sodium silicate has a wide range of uses, almost covering all sectors of the national economy. Its industrial production process adopts an intermittent production process.

[0003] In existing technologies, the production process requires injecting the produced sodium silicate fluid into a filter tank. In the filter tank, the fluid is filtered under negative pressure by filter rods, causing the sodium silicate fluid to pass through the filter rods and be drawn out of the filter tank. Then, impurities in the fluid are discharged. However, the impurities contain unreacted quartz sand, which adheres to the outer surface of the filter rods during the filtration process, clogging the filter pores and reducing filtration efficiency. Therefore, the filter rods need to be removed from the filter tank periodically, and their outer surfaces need to be cleaned. This process is cumbersome and reduces production efficiency. To address the problem of cleaning the quartz sand adhering to the outer surface of the filter rods, a continuous sodium silicate production filtration device is designed. Summary of the Invention

[0007] In the above technical solution, preferably, the discharge pipe is fixedly connected to the upper end of the production box and to the inner cavity of the collection tray, and the side of the discharge pipe away from the production box is fixedly connected to the vacuum suction pipe.

[0008] In the above technical solution, preferably, an air inlet pipe is fixedly installed on the top surface of the gas compressor housing, and the gas delivery pipe is fixedly connected to the upper end of the production housing.

[0009] In the above technical solution, preferably, there are forty-four filter rods, each filter rod including a first filter screen and a second filter screen. The second filter screen is fixedly sleeved on the outer surface of the first filter screen, and a third filter screen is fixedly sleeved on the outer surface of the second filter screen. The upper ends of the first filter screen, the second filter screen and the third filter screen are fixedly connected to the bottom surface of the collection tray.

[0010] In the above technical solution, preferably, the first and third filter screens are metal filter screens, and the second filter screen is a plastic particle filter screen.

[0011] In the above technical solution, preferably, there is a gap between the five pile wheels, the outer surface of the pile wheel near the rotating column is movably connected to the rotating column, and the outer surface of the pile wheel away from the rotating column is movably connected to the inner cavity wall of the production box.

[0012] In the above technical solution, preferably, the lower end of the production box is funnel-shaped and has a slag outlet. A slag outlet pipe is fixedly connected to the lower end of the slag outlet, and a third electronic valve is fixedly installed at the upper end of the slag outlet pipe. Four connecting columns are fixedly connected to the lower end of the inner cavity of the production box, and partitions are fixedly connected to the upper ends of the four connecting columns. The partitions are umbrella-shaped.

[0013] In the above technical solution, preferably, the gas distribution pipe includes a fourth gas guide ring and a connecting pipe. The inner ring of the fourth gas guide ring is provided with a third gas guide ring, the inner cavity of the third gas guide ring is provided with a second gas guide ring, and the inner ring of the second gas guide ring is provided with a first gas guide ring. The first, second, third, and fourth gas guide rings are interconnected through three connecting pipes. The first, second, third, and fourth gas guide rings are fixedly connected to the collection tray and each of them is provided with an air outlet pipe at its lower end. Each air outlet pipe is movably sleeved in the inner cavity of the filter rod and has an air guide hole on its outer surface. The gas delivery pipe is fixedly connected to the second gas guide ring.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0015] This invention achieves convenient cleaning of the filter screen through a structure including a gas compressor housing, a gas distribution pipe, a felt wheel, and a motor. The first electronic valve is closed, the fourth electronic valve is opened, and the gas compressor housing is started to compress external air, which is then transported into the gas distribution pipe through the gas delivery pipe. Air is then discharged from the outlet pipe of the gas distribution pipe into the filter rod and the collection tray. This allows the liquid in the collection tray and filter rod to be discharged from the filter rod in the order of the first, second, and third filter screens into the inner cavity of the production chamber. During the discharge process, the quartz sand adhering to the outer surface of the third filter screen is cleaned. Furthermore, while the filter rod is filtering the liquid in the inner cavity of the production chamber, the motor is started, causing the felt wheel to rotate around the rotating column. As the filter rod passes through the gaps between the felt wheels, the felt wheels clean the quartz sand adhering to the outer surface of the third filter screen. In summary, this invention achieves convenient cleaning of the filter screen.

[0016] This invention achieves high filtration efficiency through a structure including filter rods, fluff wheels, and a motor. It employs a three-layer filtration system (first, second, and third filter screens) to improve filtration quality. During filtration, the motor drives a rotating column, which in turn rotates the stirring column and fluff wheels around the rotating column, uniformly agitating the liquid within the production chamber. This ensures the liquid flows smoothly and mixes evenly, preventing the accumulation of quartz sand near the outside of the filter rods and reducing filtration efficiency. Furthermore, as the filter rods pass through the gaps between the fluff wheels, the fluff wheels clean the quartz sand from the outer surface of the third filter screen, further agitating the liquid within the production chamber and ensuring high filtration efficiency.

[0017] This invention achieves convenient slag discharge through structures such as a slag discharge pipe, a third electronic valve, and a baffle. Since the density of quartz sand is greater than that of liquid sodium silicate, the funnel-shaped design at the bottom of the production chamber and the umbrella-shaped design of the baffle allow the quartz sand to slide from the gap between the baffle and the production chamber to the bottom of the inner cavity of the production chamber. Then, under the obstruction of the baffle, the quartz sand is less likely to be thrown up from the bottom of the production chamber. When the third electronic valve is opened, the quartz sand can be discharged through the slag discharge port from the slag discharge pipe, thus achieving convenient slag discharge.

Detailed Implementation

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] like Figures 1 to 7 As shown, this invention provides a continuous sodium silicate production filtration device, including a production chamber 1. A collection tray 19 is fixedly connected to the top surface of the inner cavity of the production chamber 1. A filter rod 20 is fixedly connected to the lower end of the collection tray 19. A motor 6 is fixedly installed in the middle of the top surface of the production chamber 1. A rotating column 15 is fixedly connected to the output end of the motor 6 shaft. A connecting plate 16 is fixedly connected to the lower outer end of the rotating column 15. Five stirring columns 17 are fixedly connected to the upper end of the connecting plate 16. A felt wheel 18 is connected to the outer upper end of the stirring column 17 through a bearing. A gas compressor housing 9 is fixedly installed at the front end of the top surface of the body 1. A gas supply pipe 21 is fixedly connected to the rear end of the gas compressor housing 9. A fourth electronic valve 11 is fixedly installed at the front end of the gas supply pipe 21. The lower end of the gas supply pipe 21 is fixedly connected to the upper end of the collection plate 19. A gas distribution pipe 22 is fixedly connected to the bottom surface of the inner cavity of the collection plate 19. The lower end of the gas supply pipe 21 is fixedly connected to the upper end of the gas distribution pipe 22. A discharge pipe 2 is fixedly connected to the side of the upper end of the collection plate 19 away from the gas supply pipe 21. A first electronic valve 3 is fixedly installed at the upper end of the discharge pipe 2.

[0028] like Figure 2 As shown, a feed pipe 4 is fixedly connected to the top surface of the production chamber 1 away from the discharge pipe 2. The lower end of the feed pipe 4 is fixedly penetrated to the top surface of the production chamber 1 and communicates with the inner cavity of the production chamber 1. A second electronic valve 5 is fixedly installed at the upper end of the feed pipe 4. Sodium silicate filter liquid material is fed into the production chamber 1 through the feed pipe 4. First, the second electronic valve 5 is opened to start the liquid injection. When the liquid injection height is higher than the filter rod 20, the second electronic valve 5 is closed to stop the injection, so that the filtration of sodium silicate can begin.

[0029] like Figure 1 , Figure 2 and Figure 5 As shown, the discharge pipe 2 is fixedly connected to the upper end of the production chamber 1 and to the inner cavity of the collection tray 19; the side of the discharge pipe 2 away from the production chamber 1 is fixedly connected to the vacuum suction pipe, and the top surface of the gas compressor housing 9 is fixedly installed with an air inlet pipe 10, and the gas delivery pipe 21 is fixedly connected to the upper end of the production chamber 1; when filtering, the first electronic valve 3 is opened, so that the discharge pipe 2 is connected to the vacuum suction pipe. Under the action of the vacuum suction pipe, the collection tray 19 and the filter rod 20 are under negative pressure, so that the liquid passes through the filter rod 20, then enters the inner cavity of the collection tray 19, and is then sucked up and collected through the discharge pipe 2; when the gas compressor housing 9 is working, the external air passes through the air inlet pipe The compressed air enters the gas compressor housing 9 through channel 10 and is compressed. The first electronic valve 3 is closed, and the fourth electronic valve 11 is opened, injecting the compressed air into the gas distribution pipe 22 through the gas delivery pipe 21. The air then enters the inner cavity of the collection tray 19 and the filter rod 20 from the gas distribution pipe 22, causing the sodium silicate filtered in the collection tray 19 and the filter rod 20 to enter the inner cavity of the production chamber 1 in the opposite direction through the filter rod 20. During this process, the quartz sand attached to the outer surface of the filter rod 20 is washed into the solution in the inner cavity of the production chamber 1, thereby reducing the quartz sand attached to the filter holes on the outer surface of the filter rod 20 and increasing the filtration efficiency when filtering the liquid again.

[0030] like Figure 3 and Figure 7As shown, there are forty-four filter rods 20, each including a first filter screen 2001 and a second filter screen 2002. The second filter screen 2002 is fixedly sleeved on the outer surface of the first filter screen 2001, and a third filter screen 2003 is fixedly sleeved on the outer surface of the second filter screen 2002. The upper ends of the first filter screen 2001, the second filter screen 2002, and the third filter screen 2003 are fixedly connected to the bottom surface of the collection tray 19. The first filter screen 2001 and the third filter screen 2003 are metal filter screens, and the second filter screen 2002 is a plastic particle filter screen. The sodium silicate filter liquid material in the inner cavity of the production box 1 passes through the first filter screen 2001. 1. The three-layer filtration system, consisting of the second filter screen 2002 and the third filter screen 2003, reduces impurities in the liquid entering the inner cavity of the filter rod 20, ensuring the quality of the filtered liquid. Due to the material properties of the first filter screen 2001, the second filter screen 2002, and the third filter screen 2003, the second filter screen 2002 has a better filtration effect than the first filter screen 2001 and the third filter screen 2003. At the same time, the first filter screen 2001 and the third filter screen 2003 provide strength support for the second filter screen 2002, making the filter rod 20 less prone to damage and allowing for long-term reuse after cleaning the outer surface of the filter rod 20.

[0031] like Figure 2 , Figure 6 and Figure 7 As shown, there are gaps between the five agitator wheels 18. The outer surface of the agitator wheel 18 on the side closer to the rotating column 15 is movably connected to the rotating column 15, while the outer surface of the agitator wheel 18 on the side farther from the rotating column 15 is movably connected to the inner wall of the production chamber 1. The rotating column 15 is driven to rotate by the starting motor 6, which in turn drives the connecting plate 16 to rotate. The connecting plate 16 then drives the five stirring columns 17 to rotate within the production chamber 1, thereby causing the five agitator wheels 18 to rotate evenly within the production chamber 1 around the rotating column 15 as the axis of rotation. The rapid rotation and stirring of the agitator mixes the liquid flowing inside the production chamber 1, preventing the quartz sand from accumulating near the outer surface of the filter rod 20. Each time the agitator 18 rotates past the filter rod 20, the filter rod 20 can pass through the gaps between the five agitators 18, causing the agitator 18 to rotate around the agitator 17 as its axis. This cleans the rotating column 15 and the inner wall of the production chamber 1. At the same time, the agitator 18 cleans the quartz sand adhering to the outer surface of the filter rod 20, thereby increasing the filtration efficiency of the filter rod 20.

[0032] like Figure 2As shown, the lower end of the production chamber 1 is funnel-shaped and has a slag outlet 12. A slag outlet pipe 7 is fixedly connected to the lower end of the slag outlet 12, and a third electronic valve 8 is fixedly installed at the upper end of the slag outlet pipe 7. Four connecting columns 13 are fixedly connected to the lower end of the inner cavity of the production chamber 1, and a partition plate 14 is fixedly connected to the upper end of the four connecting columns 13. The partition plate 14 is umbrella-shaped. The sodium silicate filter liquid in the production chamber 1 contains quartz sand. The quartz sand cannot pass through the filter rod 20 and has a density greater than that of the sodium silicate liquid. Therefore, the quartz sand will sink to the bottom of the inner cavity of the production chamber 1. The funnel-shaped inner cavity of the production chamber 1 and the umbrella-shaped partition plate 14 facilitate the quartz sand to slide down from the gap between the partition plate 14 and the production chamber 1 and approach the slag outlet 12. At the same time, the partition plate 14 prevents the quartz sand from being stirred up when the agitator 18 drives the rotation of the production chamber 1. When discharging slag, the third electronic valve 8 is opened to allow the slag liquid to flow out from the slag outlet pipe 7.

[0033] like Figure 2 and Figure 5 As shown, the gas distribution pipe 22 includes a fourth gas guide ring 2204 and a connecting pipe 2205. The inner ring of the fourth gas guide ring 2204 has a third gas guide ring 2203, the inner cavity of the third gas guide ring 2203 has a second gas guide ring 2202, and the inner ring of the second gas guide ring 2202 has a first gas guide ring 2201. The first gas guide ring 2201, the second gas guide ring 2202, the third gas guide ring 2203, and the fourth gas guide ring 2204 are interconnected through three connecting pipes 2205. The first gas guide ring 2201, the second gas guide ring 2202, the third gas guide ring 2203, and the fourth gas guide ring 2204 are fixedly connected to the collection tray 19 and each has a gas outlet pipe 2206 at its lower end. Each gas outlet pipe 2206 is movably sleeved within the inner cavity of the filter rod 20 and externally... The surface is provided with air guide holes, and the air supply pipe 21 is fixedly connected to the second air guide ring 2202. Compressed air enters the second air guide ring 2202 through the air supply pipe 21, and then the second air guide ring 2202 guides the gas into the first air guide ring 2201, the third air guide ring 2203, and the fourth air guide ring 2204 through the connecting pipe 2205. This allows the gas to be discharged from each air outlet pipe 2206 into the inner cavity of the filter rod 20. The gas rises, causing the liquid flowing from the collection plate 19 and the filter rod 20 to pass through the first filter screen 2001, the second filter screen 2002, and the third filter screen 2003. When the liquid passes through the third filter screen 2003, it washes away the quartz sand adhering to the outer surface of the third filter screen 2003, achieving a cleaning effect and increasing the filtration efficiency.

[0034] Working principle and usage process of this invention:

[0035] Open the second electronic valve 5 to feed the sodium silicate filter material into the inner cavity of the production chamber 1 through the feed pipe 4. Open the first electronic valve 3, and the vacuum suction pipe passes through the discharge pipe 2 to create a negative pressure in the inner cavity of the collection tray 19 and the filter rod 20. This causes the liquid in the inner cavity of the production chamber 1 to pass sequentially through the third filter screen 2003, the second filter screen 2002, and the first filter screen 2001. After entering the inner cavity of the first filter screen 2001, it enters the inner cavity of the collection tray 19 and is finally sucked out through the discharge pipe 2. During the filtration process, start the motor 6 to drive the rotating column 15 to rotate. The rotating column 15 drives the connecting plate 16 and the stirring column 17 to rotate around the rotating column 15 as the axis of rotation, thereby driving the filament... The fluff wheel 18 rotates at a constant speed around the rotating column 15, which stirs and mixes the liquid flowing inside the production chamber 1, preventing the quartz sand from gathering near the outer surface of the filter rod 20. At the same time, when the fluff wheel 18 rotates around the rotating column 15, the filter rod 20 passes through the gap between the fluff wheels 18, and the fluff wheel 18 cleans the quartz sand on the outer surface of the third filter screen 2003, preventing the quartz sand from clogging the filter holes and reducing the filtration effect. During the contact between the fluff wheel 18 and the filter rod 20, the fluff wheel 18 is also driven to rotate around the stirring column 17, which increases the stirring effect of the fluff wheel 18 inside the production chamber 1.

[0036] When it is necessary to clean the outer surface of the filter rod 20, close the first electronic valve 3 and the second electronic valve 5, open the fourth electronic valve 11, and start the gas compressor housing 9. External air is introduced into the gas compressor housing 9 through the air inlet pipe 10, compressed, and then input into the second air guide ring 2202 through the air delivery pipe 21. The second air guide ring 2202 is then input into the first air guide ring 2201, the third air guide ring 2203, and the fourth air guide ring 2204 through the connecting pipe 2205. The gas is then introduced into each air outlet pipe 2206 and discharged into the inner cavity of each first filter screen 2001. This allows the liquid in the collection tray 19 and the inner cavity of the filter rod 20 to pass through the first filter screen 2001, the second filter screen 2002, and the third filter screen 2003 in sequence and enter the inner cavity of the production chamber 1. This process causes the quartz sand attached to the filter rod 20 to be impacted back into the liquid in the inner cavity of the production chamber 1, thus completing the cleaning of the filter rod 20 and ensuring filtration efficiency.

[0037] Because the density of quartz sand is greater than that of the solution, the quartz sand will sink to the bottom. Through the funnel-shaped design at the lower end of the production tank 1 and the umbrella-shaped design of the partition plate 14, the quartz sand will slide into the bottom of the production tank 1 through the gap between the partition plate 14 and the production tank 1. Under the blocking effect of the stirring column 17, the quartz sand at the bottom of the production tank 1 will not be stirred up during the process of the agitator 18 stirring the liquid in the production tank 1. When discharging slag, the third electronic valve 8 is opened to discharge the quartz sand slag liquid from the slag outlet pipe 7.
