DETAILED DESCRIPTION

[0039] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0040] like Figure 1-Figure 15 As shown, a silica sol concentration and filtration device proposed in one embodiment of the present application includes:

[0041] A carrier 1, a concentration tank 2 is mounted on the carrier 1, and a heating component 3 for heating the concentration tank 2 is mounted on the concentration tank 2;

[0042] The condensation mechanism 4 includes a condensation tank 401 and a condenser 402 mounted on the carrier 1, a connecting pipe 403 is connected between the condensation tank 401 and the condenser 402, and a steam pipe 404 is connected between the air inlet end of the condenser 402 and the top of the concentration tank 2;

[0043] The filtering mechanism 5 includes a discharge pipe 501 connected to the bottom of the concentration tank 2, and a solenoid valve is installed on the discharge pipe 501. A plurality of filter elements 503 are installed on the carrier 1. The plurality of filter elements 503 are connected to each other. The filter element 503 at the head is connected to the free end of the discharge pipe 501, and the filter element 503 at the tail is installed with a discharge pipe 502. Specifically, the free end of the discharge pipe 502 can be connected to the suction pump 1501 to extract the silica sol in the concentration tank 2. A one-way valve is installed on the discharge pipe 501 to prevent backflow.

[0044] The filter element 503 has a filter portion, and when one of the filter portions is removed, the other filter elements 503 remain connected;

[0045] The cleaning mechanism 6 is installed on the carrier 1, and is used to clean the filter part. That is to say, when in use, the silica sol to be concentrated is first poured into the concentration tank 2, and then the silica sol in the concentration tank 2 is heated by the heating component 3, and the generated steam is condensed into liquid by the condenser 402 and transported to the condensation tank 401. In the process of concentrating the silica sol, the impurities inside the filter part can be cleaned by the cleaning mechanism 6. When the silica sol in the concentration tank 2 is concentrated, the solenoid valve on the discharge pipe 501 is opened, and then the suction pump 1501 is started to draw the silica sol inside the concentration tank 2 into the discharge pipe 501, so that the silica sol enters the multiple filter elements 503 in sequence. The silica sol first passes through the filter element 503 at the head, and finally passes through the filter element 503 at the tail. The filter element 503 is discharged into the discharge pipe 502, thereby completing the filtering process of the concentrated silica sol. In the process of the silica sol passing through multiple filter elements 503, if one or more filter elements 503 need to be replaced, the corresponding filter part can be directly disassembled, and the silica sol can be normally extracted without affecting the silica sol, thereby improving the filtering efficiency, without interrupting the discharge, and indirectly improving the work efficiency. Compared with the prior art, in the process of concentrating the silica sol, the impurities in the multiple filter parts can be cleaned by the cleaning mechanism 6, thereby increasing the number of replacement times of the filter components and reducing the workload of the staff. In the process of discharging the silica sol, the filter part can be disassembled without interrupting the discharge process, thereby improving the work efficiency.

[0046] like Figure 1 , Figure 8 and Fig.10As shown, in some embodiments, the filter element 503 includes a mounting cylinder 5031 installed on the carrier 1, the bottom of the mounting cylinder 5031 is open, the filter portion includes a filter cylinder 5032 that is detachably inserted into the bottom of the mounting cylinder 5031, the filter cylinder 5032 is configured with a partition 5033, and a plurality of filter membrane tubes 5034 are vertically penetrated and installed on the top surface of the partition 5033, a plurality of filter holes are evenly opened on the surface of the filter membrane tube 5034, the bottom end of the filter membrane tube 5034 is connected to the bottom end of the filter cylinder 5032, the mounting cylinder 5031 at the head is connected to the discharge pipe 501, and one side of the filter cylinder 5032 at the tail is connected to the discharge pipe 502, and except for the filter cylinder 5032 at the tail, other filter cylinders 5032 are connected with connecting pipes 5035, and the connection The free end of the pipe 5035 is connected to one side of the installation tube 5031 adjacent to the discharge pipe 502. The installation tube 5031 is internally constructed with a blocking plate 5036, and a through groove 5037 is formed on the blocking plate 5036. A blocking member 7 for blocking the through groove 5037 is installed on the installation tube 5031. A butt-joint pipe 9 is connected between two adjacent installation tubes 5031. The installation tube 5031 at the tail is also connected with a butt-joint pipe 9. A connecting frame 10 is installed inside the butt-joint pipe 9. An annular plate 11 is constructed inside the butt-joint pipe 9. A sliding rod 12 is slidably inserted on the connecting frame 10. One end of the sliding rod 12 passes through the annular plate 11 and is constructed with a stopper 13, which is used to block the inner ring of the annular plate 11. A connecting spring 1 is installed between the connecting frame 10 and the stopper 13. 4, that is, the silica sol first enters the installation cylinder 5031 located at the head, and then enters the multiple filter membrane tubes 5034. The surface of the filter membrane tube 5034 is evenly provided with multiple filter holes (as shown in the figure), and the filtered silica sol enters the filter cylinder 5032, and finally enters the next installation cylinder 5031 through the corresponding connecting pipe 5035, and so on, and finally is discharged from the discharge pipe 502. In this process, if one of the installation cylinders 5031 needs to be disassembled, in this embodiment, if the filter cylinder 5032 in the middle needs to be disassembled, the through groove 5037 is blocked by the blocking member 7, and then the corresponding filter cylinder 5032 is disassembled, so that the silica sol enters the installation cylinder 5031 in the middle , because at this time, as the pressure inside the middle installation cylinder 5031 gradually increases, the connecting spring 14 is deformed so that the block 13 is not inside the shielding annular plate 11, and the silica sol located in the installation cylinder 5031 directly enters the next installation cylinder 5031 from the docking tube 9. In this embodiment, the docking tube 9 located at the rear installation cylinder 5031 can be externally connected to the suction pump 1501 to ensure that the silica sol can be normally extracted when the rear filter cylinder 5032 is disassembled. Specifically, a drainage hole is provided on one side of the bottom of the filter cylinder 5032 near the bottom, which is used to drain the water accumulated in the filter barrel. When drainage is not required, a screw (not shown in the figure) can be screwed into the drainage hole. Of course, the filter cylinder 5032 can also be directly screwed out to drain the water.You can also wait for the condensed water to be squeezed out during the discharging process of the silica sol, and then collect the concentrated silica sol after the condensed water is drained.

[0047] like Figure 1 , Figure 2 and Fig.10 As shown, in some embodiments, the sealing member 7 includes a sealing plate 701 symmetrically slidably installed and inserted on the outside of the mounting cylinder 5031, the filter cylinder 5032 is threaded into the mounting cylinder 5031, and a connecting member 8 acting on the sealing plate 701 and the mounting cylinder 5031 is installed on the mounting cylinder 5031. When the mounting cylinder 5031 is spirally rotated, the sealing plate 701 is driven to move through the connecting member 8. That is to say, when the filter cylinder 5032 is screwed out of the mounting cylinder 5031, the sealing plate 701 can be moved through the connecting member 8, thereby blocking the through groove 5037.

[0048] like Figure 1 , Figure 8 and Fig.10 As shown, in some embodiments, the linkage 8 includes a threaded swivel 801 rotatably sleeved on the outer peripheral side of the mounting cylinder 5031, the bottom end of the threaded swivel 801 is flush with the bottom end of the mounting cylinder 5031 and is configured with a limit plate 805, a sliding groove 802 is provided on the outer side of the filter cylinder 5032 along its length direction, the limit plate 805 is used to move in the sliding groove 802, a threaded slide 803 is slidably sleeved on the outer side of the mounting cylinder 5031, the threaded slide 803 is threadedly sleeved on the threaded swivel 801, a linkage rod 804 is hinged between the threaded slide 803 and the blocking plate 701, and when the filter cylinder 5032 is screwed out, the filter cylinder 5032 will drive the limit plate located in the sliding groove 802 when it rotates. 805 moves, thereby causing the limit plate 805 to move in the sliding groove 802, and the threaded ring 801 will adaptively rotate at this time, because the threaded ring 801 is threadedly matched with the threaded slide 803, so the threaded slide 803 at this time moves vertically downward, thereby driving the connecting rod 804 hinged on the threaded slide 803 to move, and the movement of the connecting rod 804 further drives the blocking plate 701 hinged thereto to move, so that the two blocking plates 701 are brought close to each other to complete the fitting. In this embodiment, after the two blocking plates 701 are completed fitting, the filter cartridge 5032 is just screwed out, so that there is no need for electric or manual control of the movement of the blocking plate 701, which is more convenient to use.

[0049] like Figure 2 and Figure 5As shown, in some embodiments, the blocking plate 701 includes a sliding plug plate 7011 horizontally slidably inserted on the mounting cylinder 5031, one end of the sliding plug plate 7011 is located outside the mounting cylinder 5031 and is slidably inserted with a connecting plate 7012, a resistance spring piece 7013 is installed between the connecting plate 7012 and the sliding plug plate 7011, and the connecting rod 804 is hinged on the connecting plate 7012, that is, when the filter cylinder 5032 is being twisted and has not yet been separated from the mounting cylinder 5031, the two sliding plug plates 7011 are already fitted together, and after the sliding plug plates 7011 are fitted together, continuing to twist the filter cylinder 5032 will cause the connecting plate 7012 to continue to move, thereby compressing the resistance spring piece 7013, thereby increasing the resistance force of the two sliding plug plates 7011, further improving the sealing effect, and effectively preventing the silica sol from overflowing from the two sliding plug plates 7011.

[0050] like Figure 1 and Figure 5-Figure 10 As shown, in some embodiments, the cleaning mechanism 6 includes a waste liquid tank 601 installed on the carrier 1, and the waste liquid tank 601 is connected to a waste liquid pipe 602, and the free end of the waste liquid pipe 602 is connected to the free end of the docking pipe 9 located on the tail filter cartridge 5032. A suction assembly 15 is installed on the carrier 1, and the condensed water inside the condensation tank 401 is sucked into the discharge pipe 502 through the suction assembly 15. When the condensed water enters the discharge pipe 502, the free end of the discharge pipe 502 is in a blocked state, that is, the condensed water in the condensation tank 401 can be sucked into the discharge pipe 502 through the suction assembly 15, and the condensed water will flow out of the discharge pipe 502. 02 enters the filter cartridge 5032 at the tail end. As the water level inside the filter cartridge 5032 rises, the condensed water passes through the filter holes on the multiple filter membrane tubes 5034 and enters the corresponding installation cartridge 5031, and finally enters the next filter cartridge 5032 through the connecting tube 5035. Similarly, when entering the installation cartridge 5031 at the head end, as the pressure inside the installation cartridge 5031 increases, the connecting spring 14 is deformed, so that the condensed water is finally discharged from the docking tube 9 at the tail end into the waste liquid pipe 602, and finally enters the waste liquid tank 601. Preferably, in this embodiment, as Figure 5As shown, the butt joint pipe 9 at the tail can be installed with a three-way regulating valve, one end of the waste liquid pipe 602 is connected to one end of the three-way regulating valve, and the other end of the three-way regulating valve is connected to the discharge pipe 502 through a pipeline, and a one-way valve is installed on the pipeline. When the condensed water is transported to the filter cartridge 5032, the three-way regulating valve is adjusted to make the waste liquid pipe 602 connected to the butt joint pipe 9 at the tail. When the concentrated silica sol needs to be transported, the three-way regulating valve can be adjusted to make the discharge pipe 502 It is connected to the docking pipe 9 at the tail, so that when the filter cartridge 5032 at the tail is disassembled, the silica sol in the installation cartridge 5031 at the tail can be transported to the discharge pipe 502. In this embodiment, the filter cartridge 5032 and the condensate remaining in the installation cartridge 5031 can be directly extracted by the suction pump 1501. Preferably, a relief valve (as shown in the figure) can be installed on the discharge pipe 501 to prevent the internal pressure of the multiple filter cartridges 5032 from being too high when the suction pump 1501 sucks the condensate.

[0051] like Figure 2 and Fig.10 As shown, in some embodiments, the suction assembly 15 includes a suction pump 1501 installed on the carrier 1, the suction end of the suction pump 1501 is connected to a liquid extraction pipe 1502, the free end of the liquid extraction pipe 1502 is connected to the condensation tank 401, the liquid outlet end of the suction pump 1501 is connected to a liquid outlet pipe 1503, the liquid outlet pipe 1503 is connected to one side of the discharge pipe 502, and a swivel member 16 is installed on the liquid outlet pipe 1503, and the swivel member 16 is used to adjust the connection state between the liquid outlet pipe 1503 and the discharge pipe 502, that is, the connection state between the discharge pipe and the liquid outlet pipe 1503 can be changed by the swivel member 16, thereby effectively preventing the condensate from being directly discharged from the discharge pipe, and also preventing the silica sol from entering the liquid outlet pipe 1503.

[0052] like Figure 1 , Figure 2 and Fig.14As shown, in some embodiments, the discharge pipe 502 and the liquid outlet pipe 1503 are both internally configured with a rectangular cavity 1607, and the two rectangular cavities 1607 are interconnected. The swivel member 16 includes a convex plate 1601 configured on the liquid outlet pipe 1503, a connecting tube 1602 is installed on the convex plate 1601, a connecting rod 1603 is slidably inserted at one end of the connecting tube 1602, a return spring 1604 is installed between the connecting rod 1603 and the connecting tube 1602, an L-shaped sealing plate 1605 is configured at the free end of the connecting rod 1603, and a stop plate 1606 is horizontally configured on the liquid outlet pipe 1503. , the return spring 1604 is used to make the sealing plate 1605 contact the side of the abutment plate 1606 close to the discharge pipe 502. That is to say, during the process of silica sol discharging, the silica sol will enter the discharge pipe 502. At this time, the sealing plate 1605 contacts the abutment plate 1606, so the silica sol will not enter the liquid outlet pipe 1503. When the condensed water enters the liquid outlet pipe 1503, as the water pressure inside the liquid outlet pipe 1503 increases, the sealing plate 1605 will move at this time, and the sealing L-shaped design will block the discharge pipe 502, so that the condensed liquid will be directly discharged from the discharge pipe 502. The filter tube 5032 at the rear portion is effectively prevented from being directly discharged from the discharge pipe 502. The diameters of the filter holes on the multiple filter membrane tubes 5034 at the head portion are successively smaller than the diameters of the filter holes on the multiple filter membrane tubes 5034. Preferably, the elastic force of the connecting spring 14 at the head portion increases successively to the connecting spring 14 at the tail portion. In this way, when the condensate enters the filter tube 5032 at the rear portion, the impurities in the filter membrane tube 5034 at the rear portion are smaller than those in the filter membrane tubes 5034 in other filter tubes 5032. In this way, the filter tube 5034 at the rear portion is The impurities in 5032 can smoothly pass through the filter holes on the next filter membrane tube 5034. When the condensed water enters the installation tube 5031 at the head, as the pressure gradually increases, the connecting spring 14 at the head will be deformed so that the condensed water passes through the ground docking tube 9 at the head and enters the next installation tube 5031, until the connecting spring 14 in the ground docking tube 9 at the tail is deformed, so that the condensed water enters the waste liquid pipe 602, and finally enters the waste liquid tank 601, so that some impurities in multiple filter tubes 5032 can be discharged into the waste liquid tank 601.

[0053] like Figure 4As shown, in some embodiments, two jackets 17 distributed up and down are installed on the outside of the concentration tank 2, and an annular cavity 18 is formed between the jacket 17 and the concentration tank 2. The two jackets 17 are connected with a heat source inlet pipe 19, and one of the heat source inlet pipes 19 is connected to one side of the other heat source inlet pipe 19. The two jackets 17 are connected with a heat source outlet pipe 20, and the free end of one of the heat source outlet pipes 20 is connected to one side of the other heat source outlet pipe 20. A solenoid valve is installed at the free end of the heat source outlet pipe 20. The heat source inlet pipe 19 is used to transport the heat carrier into the concentration tank 2. The design of the two jackets 17 distributed up and down can effectively avoid the drop of liquid level during the concentration process, resulting in material loss caused by splashing of materials to the wall and residue, and reduces the impurities mixed with the inner wall of the concentration tank 2. In this way, the frequency of cleaning the concentration tank 2 is also effectively reduced, and the purity of the silica sol is also better improved.

[0054] like Figure 1 and Figure 4 As shown, in some embodiments, a vacuum pump 21 is installed on the carrier 1, and the vacuum pump 21 is connected to the condensation tank 401 through a pipeline. A stirring rod 22 is rotatably installed on the concentration tank 2, and a motor for driving the stirring rod 22 to rotate is installed on the condensation tank 401. The design of the stirring rod 22 further improves the concentration efficiency when concentrating the silica sol. The design of the vacuum pump 21 provides a negative pressure environment for the concentration tank 2, reduces the boiling point of the solvent, and further improves the heating efficiency.
