[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] Reference Figure 1 , Figure 2 and Figure 4The utility model provides an embodiment: a silica sol concentrating device, comprising a concentrating box 1, a feed pipe 3 is fixedly connected to the outside of the concentrating box 1, a discharge pipe 2 is fixedly connected to the bottom of the concentrating box 1, a motor 4 is fixedly connected to the top of the concentrating box 1, a rotating rod 15 is rotatably connected to the inner top wall of the concentrating box 1, a gear 2 13 is fixedly connected to the outside of the rotating rod 15, a support frame 24 is fixedly connected to the bottom end of the rotating rod 15, a filter membrane 16 is fixedly connected to the inside of the support frame 24, two connecting rods 14 are rotatably connected to the inner top wall of the concentrating box 1, and the outer ends of the connecting rods 14 are fixedly connected to the gear 2 13. A plurality of scrapers 23 are fixedly connected to the top of the concentrating tank 1, a gear 12 is fixedly connected to the outside of the connecting rod 14, a drain pipe 10 is fixedly connected to the outside of the concentrating tank 1, a filter screen 9 is slidably connected to the top of the drain pipe 10, two slots 22 are provided on the outside of the filter screen 9, two mounting slots 18 are provided on the outside of the drain pipe 10, a baffle 20 is slidably connected to the inner wall of the mounting slot 18, a pull rod 11 is fixedly connected to one side of the baffle 20, a spring 19 is provided on the outside of the pull rod 11, a block 21 is fixedly connected to the other side of the baffle 20, and a drying component is installed on the top of the concentrating tank 1.

[0031] Specifically, silica sol stock solution is added into the filter membrane 16 through the feed pipe 3, and the motor 4 is started. The output end of the motor 4 drives the rotating rod 15 to rotate, and then drives the support frame 24 and the gear 2 13 to rotate at the same time to filter the silica sol stock solution. At the same time, under the meshing action of the gear 2 13, the two gears 12 rotate at the same time, and the gear 1 12 drives the connecting rod 14 to rotate, and then drives the scraper 23 to rotate, so as to scrape off the large particles of silica sol on the surface of the filter membrane 16, and maintain the permeability of the filter membrane 16, so as to ensure the continuity and stability of the production process and improve the production efficiency. The function of the support frame 24 is to drive the filter membrane 16 to rotate through its own rotation. By rotating the filter membrane 16, the filtration time of the silica sol is shortened, and the concentration efficiency is improved. The concentrated wastewater is discharged through the drain pipe 10, and the wastewater is collected and treated, and the impurities in the wastewater are filtered through the filter screen 9.

[0032] Reference Figure 1 The drying component includes a heating box 5, a blower 6 is fixedly connected to the top of the heating box 5, a conduit 8 is fixedly connected to the outside of the heating box 5, and an air pump 7 is fixedly connected to the outside of the conduit 8.

[0033] Specifically, the blower 6 is started, and the external air is drawn by the blower 6 and transported into the heating box 5, and then the air is heated by the heating wire inside the heating box 5. The air pump 7 is turned on, and the extraction end of the air pump 7 draws the heated air in the heating box 5, and then enters the interior of the concentration box 1 through the conduit 8 to dry the residual moisture in the silica sol after concentration. Drying can make the silica sol particles more evenly distributed, avoid particle aggregation or precipitation, and is beneficial to the subsequent process and product quality control.

[0034] Reference Figure 2 The outside of gear 1 12 is meshedly connected with the outside of gear 2 13 at the corresponding position, and a discharge valve 17 is fixedly connected to the bottom of the filter membrane 16 .

[0035] Specifically, the gear 2 13 drives the two gears 12 to rotate by meshing. When the silica sol needs to be concentrated, the discharge valve 17 is closed to prevent the silica sol from flowing out of the filter membrane 16 and affecting the filtering effect. When the concentration is completed, the discharge valve 17 is opened to facilitate the removal of the silica sol.

[0036] Reference Figure 1 A heating wire is fixedly connected to the interior of the heating box 5 , and one end of the conduit 8 away from the heating box 5 is connected to the outside of the concentration box 1 .

[0037] Specifically, the air in the heating box 5 is heated by the heating wire, and the heated air is then transported to the interior of the concentration box 1 through the conduit 8 to further remove moisture from the concentrated silica sol.

[0038] Reference Figure 3 and Figure 4 One end of the spring 19 is fixedly connected to the inner wall of the mounting groove 18 , and the other end of the spring 19 is fixedly connected to the outer side of the baffle 20 .

[0039] Specifically, under the elastic force of the spring 19 , the baffle 20 is prevented from sliding freely along the inner wall of the installation groove 18 , thereby causing the block 21 to be separated from the groove 22 , further improving the stability of the filter screen 9 .

[0040] Reference Figure 3 and Figure 4 One end of the two pull rods 11 passes through the drain pipe 10, one end of the pull rod 11 is provided with an anti-slip pattern, and the top of the filter screen 9 is fixedly connected with a pull ring.

[0041] Specifically, it is convenient for the staff to pull the pull rod 11, the anti-slip pattern increases the friction force so that the pull rod 11 is easier to be pulled or controlled, and the pull ring is convenient for the staff to take out or place the filter 9.

[0042] Reference Figure 3 and Figure 4 The longitudinal section of the card block 21 is a square, and the card block 21 and the card slot 22 are plug-fitted.

[0043] Specifically, the filter screen 9 is fixed by inserting the clamping block 21 into the clamping slot 22, thereby further increasing the stability of the filter screen 9 and thus improving the filtering efficiency.

[0044] Reference Figure 1 The bottom of the concentration box 1 is fixedly connected with four support columns, and the bottom of the support columns is fixedly connected with an anti-slip pad.

[0045] Specifically, a stable supporting relationship is established between the bottom of the support column concentration box 1 and the ground, which effectively prevents the concentration box 1 from tilting or shaking. The function of the anti-slip pad is to increase the friction of the support column and further improve the stability of the concentration box 1.

[0046] Working principle: When this device is used, silica sol stock solution is added to the filter membrane 16 through the feed pipe 3, and the motor 4 is started. The output end of the motor 4 drives the rotating rod 15 to rotate. Under the action of the rotating rod 15, the support frame 24 and the gear 2 13 rotate at the same time. The support frame 24 drives the filter membrane 16 to rotate, and the silica sol stock solution is filtered. The filtered wastewater is discharged through the drain pipe 10. The function of the filter screen 9 is to filter impurities in the wastewater to facilitate the subsequent treatment of the wastewater. At the same time, the gear 2 13 drives the two gears 1 12 to rotate at the same time through meshing, and the gear 1 12 drives the connecting rod 14 to rotate, and then drives the scraper 23 to rotate, and the large particles of silica sol on the inner surface of the filter membrane 16 are scraped off. The scraper 23 can more evenly remove the blockage on the surface of the filter membrane 16 to ensure the stability and durability of the filtering effect.

[0047] In addition, the blower 6 is started to convey air into the heating box 5, and then the air is heated by the heating wire inside the heating box 5. The air pump 7 is turned on, and the heated air enters the interior of the concentration box 1 through the conduit 8 under the action of the air pump 7, so as to dry the residual moisture of the silica sol after concentration, thereby making the silica sol more stable, less prone to agglomeration or deformation, which is conducive to storage and transportation, and easier to handle in subsequent processes.
