[0002] Potassium fluorosilicate is mainly used in wood preservation, ceramic manufacturing, aluminum and magnesium smelting, agricultural pesticides, optical glass manufacturing, synthetic mica and porcelain enamel manufacturing, etc.
[0003] Currently, most existing mixing equipment for potassium fluorosilicate preparation uses single-shaft agitation, which results in poor uniformity of raw material mixing inside the equipment, reducing the production efficiency of potassium fluorosilicate. At the same time, the raw materials mix slowly around the mixing tank during agitation, which easily causes the raw materials to clump and stick to the tank wall, further reducing the equipment's production efficiency.

[0010] Preferably, the ball valve has an internal vent hole, and multiple vent rings are fixedly connected to the inner side of the vent pipe.
[0011] Preferably, a check valve is movably connected inside the nozzle, and a filter screen is fixedly connected to the outer surface of the nozzle.

[0015] The advantages of this application are: (1) When the equipment mixes raw materials, the rotating shaft drives the ring rack to rotate, so that the guide plate follows the ring rack to rotate, so that the guide plate scrapes off the raw materials stuck to the upper surface inside the mixing tank, and at the same time, the raw materials around are guided to form turbulence, so that the raw materials are mixed more evenly and the equipment production efficiency is improved.
[0016] (2) When the equipment is mixing raw materials, the rotating shaft drives the ball valve to rotate.

[0025] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.
[0026] Example 1, referring to Figures 1-4, provides a raw material mixing device for potassium fluorosilicate preparation, including a hollow base 100, a support frame 200 on the top of the hollow base 100, a mixing tank 300 on the top of the support frame 200, and a sealing cover 400 on the top of the mixing tank 300 to prevent leakage during raw material mixing. A feeding port 500 is provided on the surface of the sealing cover 400 for the operator to add raw materials. A rotating shaft 700 is disposed inside the sealing cover 400; a belt head 901 is fixedly connected to the outer side of the rotating shaft 700, and the rotating shaft is movably connected inside the sealing cover 400. A belt head 903 is fixedly connected to the outer side of the rotating shaft 902. A belt 904 is movably connected between the belt head 901 and the belt head 903. The belt 904 drives the belt head 903 to rotate with the belt head 901. A bevel gear 905 is fixedly connected to the bottom of the rotating shaft 902. A slide rail 908 is fixedly connected to the bottom surface of the sealing cover plate 400. The slide rail 908 allows the slide rod 907 to move along the slide rail 908. The slide rod 907 is slidably connected inside the slide rail 908. A ring rack 906 is fixedly connected to the bottom of the slide rod 907. The ring rack 906 meshes with the bevel gear 905. A fixed plate 909 is fixedly connected to the bottom of the mixing tank 300. A guide plate 910 is fixedly connected to the bottom surface of the fixed plate 909, and guide fins 911 are fixedly connected to the bottom surface of the guide plate 910. The guide fins 911 improve the flow guiding efficiency of the guide plate 910. A discharge pipe 600 is fixedly connected to the bottom of the mixing tank 300. A ribbon agitator 800 is fixedly connected to the outside of the rotating shaft 700. The ribbon agitator 800 makes the raw materials in the mixing tank 300 mix more quickly. An intermittent jet assembly 1000 is fixedly connected to the outside of the mixing tank 300. A real-time monitoring assembly 1100 is fixedly connected to the outside of the mixing tank 300. A variable pitch agitator blade is fixedly connected inside the ribbon agitator 800. The mixing blades are positioned such that the raw materials are tumbled both axially and radially. Defoaming needles are fixedly connected to the surface of the variable-pitch mixing blades, making the mixing of raw materials more efficient. The outer surface of the guide plate 910 is in contact with the inner surface of the mixing tank 300, and slits are opened on both sides of the guide plate 910. When the equipment is mixing raw materials, the rotation of the rotating shaft 700 drives the rotation of the annular rack 906, causing the guide plate 910 to rotate with the annular rack 906. This allows the guide plate 910 to scrape off the raw materials adhering to the upper surface inside the mixing tank 300, while simultaneously guiding the surrounding raw materials to form turbulence, thus making the mixing of raw materials more uniform, accelerating the mixing speed, and improving the equipment's production efficiency.
[0027] When the above-mentioned equipment is in use, the motor is started, causing the rotating shaft 700 to rotate and the ribbon agitator 800 to rotate, thus initiating the mixing of raw materials. Since the flowability of the raw materials at the periphery is less than that at the center, the raw materials at the periphery are prone to clumping and sticking to the walls. The rotating shaft 700 drives the belt head 901 to rotate, which in turn drives the belt head 903 via the belt 904, causing the rotating shaft 902 to rotate. This causes the bevel gear 905 to rotate, which in turn drives the ring rack 906 to rotate, causing the slide rod 907 to slide along the slide rail 908. The guide plate 910 follows the rotation of the ring rack 906, scraping off the raw materials sticking to the upper surface inside the mixing tank 300. At the same time, the raw materials at the periphery are guided to form turbulence, thus making the mixing of raw materials more uniform, accelerating the mixing speed, and improving the production efficiency of the equipment.
[0028] Example 2, referring to Figures 1-6, is based on Example 1. The intermittent jet assembly 1000 includes gear 1001, gear 2 1002, shaft 3 1003, bevel gear 2 1004, bevel gear 3 1005, ball valve 1006, air inlet pipe 1007, fixing ring 1008, air outlet pipe 1009, and nozzle 1010. Gear 1001 is fixedly connected to the outer side of shaft 1 700, and shaft 1001 is movably connected to the inside of sealing cover plate 400. A gear 1002 is fixedly connected to the outer side of shaft 1003 (shaft 3). Gear 1002 meshes with gear 1001. A bevel gear 1004 is fixedly connected to the top of shaft 1003. A retaining ring 1008 is fixedly connected to the top of sealing cover 400. An air intake pipe 1007 is fixedly connected to the top of retaining ring 1008. A ball valve 1006 is movably connected inside the air intake pipe 1007. The ball valve 1006 controls the air intake. Gas flows through the vent pipe 1007. A bevel gear 1005 is fixedly connected to the left side of the ball valve 1006, meshing with a bevel gear 1004. An outlet pipe 1009 is fixedly connected to the bottom of the fixing ring 1008, and a nozzle 1010 is fixedly connected to the inner side of the outlet pipe 1009. The nozzle 1010 sprays inert gas in various directions into the mixing tank 300. A vent hole is provided inside the ball valve 1006, and the outlet pipe 100... Multiple air outlet rings are fixedly connected to the inner side of nozzle 9; a check valve is movably connected inside nozzle 1010, and a filter screen is fixedly connected to the outer surface of nozzle 1010; an intermittent jet assembly 1000 is provided. When the equipment mixes raw materials, the rotating shaft 700 drives the ball valve 1006 to rotate. At this time, inert gas is introduced into the air inlet pipe 1007, causing nozzle 1010 to intermittently spray gas into the mixing tank 300, thereby forming microbubble disturbance, breaking up material agglomerates, and making the raw materials more uniformly mixed.
[0029] When the above equipment is used, during the mixing process of raw materials, the raw materials are prone to precipitation and agglomeration due to local differences in proportion. At this time, the rotating shaft 700 drives the gear 1001 to rotate, which in turn drives the gear 1002 to rotate, causing the rotating shaft 1003 to rotate, causing the bevel gear 1004 to rotate, and the bevel gear 1005 to rotate, causing the ball valve 1006 to rotate. This causes the inert gas entering through the air inlet pipe 1007 to intermittently enter the air outlet pipe 1009, which in turn causes the nozzle 1010 to intermittently spray inert gas into the raw materials, thereby forming microbubble disturbance, breaking up the material agglomerates, making the raw materials more uniformly mixed, and thus improving the production efficiency of the equipment.
[0030] Example 3, referring to Figures 1-8, is based on Example 1. The real-time monitoring component 1100 includes an inlet pipe 1101, a flow cup 1102, a flow pipe 1103, an outlet pipe 1104, an online particle size analyzer 1105, a communication line 1106, a control panel 1107, a mounting bracket 1108, and an electric valve 1109. The inlet pipe 1101 is fixedly connected to the outside of the mixing tank 300. The flow cup 1102 is fixedly connected to the left side of the inlet pipe 1101. The flow cup 1102 allows for automatic sampling. A flow pipe 1103 is provided inside the flow cup 1102. The online particle size analyzer 1105 is fixedly connected inside the flow pipe 1103. The online particle size analyzer 1105 allows for real-time monitoring of the raw material mixing degree. The outlet pipe 1104 is fixedly connected to the left side of the flow cup 1102. The communication line 1106 is fixedly connected to the top of the online particle size analyzer 1105. A support bracket is also included. The control panel 1107 is fixedly connected internally to the 200. A fixing frame 1108 is fixedly connected to the top of the hollow base 100, and an electric valve 1109 is fixedly connected to the top of the fixing frame 1108. The horizontal height of the inlet pipe 1101 is lower than that of the outlet pipe 1104. A corrosion-resistant shell is fixedly connected to the outside of the bottom electrode of the online particle size analyzer 1105. An explosion-proof connector is fixedly connected at the connection between the communication line 1106 and the online particle size analyzer 1105, and an explosion-proof terminal is fixedly connected at the connection between the communication line 1106 and the control panel 1107. A real-time monitoring component 1100 is set up. When the raw materials are mixed, part of the mixture enters the flow cup 1102 from the inlet pipe 1101, so that the online particle size analyzer 1105 can detect the dispersion of materials inside the mixture and feed the data back to the control panel 1107 in real time, thereby automatically judging the degree of raw material mixing. When the raw material mixing is completed, a feedback signal is sent to the electric valve 1109, thereby realizing automatic unloading.
[0031] When using the above equipment, it is necessary to monitor the degree of mixing of raw materials inside the mixing tank 300 in real time during the mixing process. At this time, the mixed liquid enters the flow cup 1102 from the inlet pipe 1101, allowing the online particle size analyzer 1105 to monitor the dispersion of materials in the mixed liquid in real time. Then, the mixed liquid re-enters the mixing tank 300 from the outlet pipe 1104. When the raw material mixing meets the standard, the online particle size analyzer 1105 transmits the signal to the control panel 1107 through the communication line 1106, causing the control panel 1107 to control the electric valve 1109 to rotate and open, allowing the finished product in the mixing tank 300 to be discharged from the discharge pipe 600, thereby realizing the functions of automatic unloading and real-time monitoring of material conditions.
[0032] The above are merely preferred embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
