Description

Technical Field

[0001] The utility model relates to the technical field of impurity removal in metal silicon smelting, in particular to an impurity removal and filtration device for metal silicon smelting. Background Art

[0002] "Metal silicon" (also known as industrial silicon in China) is a commodity name that emerged in the mid-1960s. Its emergence is related to the rise of the semiconductor industry. The international common practice is to divide commodity silicon into metal silicon and semiconductor silicon. Metal silicon is a product smelted from quartz and coke in an electric furnace. The content of the main component silicon element is about 98% (silicon content of 99.99% is also included in metal silicon), and the remaining impurities are iron, aluminum, calcium, etc. Semiconductor silicon is used to make high-purity metal silicon for semiconductor devices.

[0003] Metal silicon is often used to make semiconductors, alloys, and organosilicon polymer materials. It is a rare material. However, during the smelting and impurity removal processes, due to reasons such as insufficient reaction, the loss of silicon elements or insufficient purity of the refined product often occurs, causing certain losses to producers. Summary of the Utility Model

[0004] To solve the above technical problems, the utility model provides an impurity removal and filtration device for metal silicon smelting.

[0005] The utility model is realized by the following technical solutions: An impurity removal and filtration device for metal silicon smelting includes a mixing mechanism, a filtration mechanism, and a main body mechanism. The mixing mechanism is located at the top of the main body mechanism, and the filtration mechanism is located at the bottom of the main body mechanism.

[0006] The mixing mechanism includes a motor. The outer wall of the motor is fixedly connected with a rotating shaft. The outer wall of the rotating shaft is fixedly connected with a fixed connecting rod. The inner wall of the fixed connecting rod is rotatably connected with an outer gear. The lower surface of the outer gear is fixedly connected with a stirring rod.

[0007] Through the above technical solutions, the motor is fixedly connected to the rotating shaft, and the rotating shaft is driven to rotate by the motor. The rotating shaft is fixedly connected to the fixed connecting rod, and the fixed connecting rod is rotatably connected to the outer gear. Thus, the rotation of the rotating shaft drives the fixed connecting rod and the outer gear to rotate. By fixedly connecting the stirring rod to the lower surface of the outer gear, when the motor drives mechanical parts such as the rotating shaft to rotate, the stirring rod simultaneously revolves with the outer gear, thereby stirring the solution to be filtered inside the mechanical equipment, increasing the mixing degree of the solution and the flocculant, and making the reaction more sufficient.

[0008] As a further improvement of the above solution, the outer wall of the outer gear is meshed with an inner gear, and the outer wall of the inner gear is fixedly connected with a gear box.

[0009] Through the above technical solution, the external gear meshes with the internal gear. By setting the internal gear and the external gear to be meshed and connected, when the external gear is driven by equipment such as a motor to revolve, it drives itself to rotate by meshing with the internal gear through its outer wall. Thus, the stirring rod fixedly connected can be made to rotate. By making the stirring rod rotate while revolving, the degree of mixing is increased, enabling the reaction to be completed more fully, facilitating subsequent filtration work, and preventing the presence of impurities from affecting the purity.

[0010] As a further improvement of the above solution, a first fixing nut is threadedly connected to the outer wall of the motor.

[0011] Through the above technical solution, the motor is threadedly connected to the first fixing nut. By setting the first fixing nut to fixedly connect the motor to the outer wall of the spherical sealing cover, it is possible to prevent shaking and abnormal noises caused by the loosening of mechanical equipment during operation, and at the same time, the stability of the overall mechanical mechanism is increased.

[0012] As a further improvement of the above solution, the filtering mechanism includes a cylinder. A main body housing is fixedly connected to the outer wall of the cylinder. A discharge port is fixedly connected to the outer wall of the main body housing. A feed port is fixedly connected to the outer wall of the main body housing. A ball valve is rotatably connected to the inner wall of the feed port. A knob is fixedly connected to the outer wall of the ball valve.

[0013] Through the above technical solution, the feed port and the discharge port are respectively fixedly connected to the outer wall of the main body housing. By arranging ball valves inside the feed port and the discharge port, the feed and discharge are controlled by the ball valves. The ball valve is fixedly connected to the knob. By setting the knob to control the opening and closing of the ball valve, the raw materials are controlled to enter by opening the feed port and closing the discharge port during feeding, and vice versa during discharging.

[0014] As a further improvement of the above solution, a filter screen is fixedly connected to the outer wall of the cylinder.

[0015] Through the above technical solution, the cylinder is fixedly connected to the filter screen. By setting the filter screen to be inside the mechanical equipment and closely attached to the lower surface of the equipment, when the mechanical equipment completes the reaction and discharges the material, the cylinder controls the filter screen to move upward, so that the solid sediment in the liquid can be filtered out by adhering to the surface of the filter screen.

[0016] As a further improvement of the above solution, the main body mechanism includes a main body housing. A support frame is fixedly connected to the lower surface of the main body housing. A spherical sealing cover is fixedly connected to the upper surface of the main body housing.

[0017] Through the above technical solution, the main body housing is fixedly connected to the support frame. By setting the support frame to be fixedly connected to the main body housing, the stability of the overall mechanical structure is increased.

[0018] As a further improvement of the above solution, a flocculant inlet is fixedly connected to the outer wall of the spherical sealing cover, and a second fixing nut is threadedly connected to the inner wall of the spherical sealing cover.

[0019] Through the above technical solution, the spherical sealing cover is threadedly connected to the second fixing nut, and the spherical sealing cover is fixed on the upper surface of the main body housing by setting the second fixing nut, thereby increasing the sealing performance of the overall mechanical structure.

[0020] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0021] In the present utility model, a motor is fixedly connected to a rotating shaft, the rotating shaft is driven by the motor to rotate, a fixed connecting rod is fixedly connected to the rotating shaft, the fixed connecting rod is rotatably connected to an external gear, so that the fixed connecting rod and the external gear are driven to rotate by the rotation of the rotating shaft. A stirring rod is fixedly connected to the lower surface of the external gear. When the motor drives mechanical parts such as the rotating shaft to rotate, the stirring rod simultaneously revolves with the external gear, thereby stirring the solution to be filtered inside the mechanical equipment, increasing the mixing degree of the solution and the flocculant, making the reaction more sufficient. The external gear meshes with the internal gear, so that the external gear rotates both around its own axis and around the internal gear, enhancing the mixing effect of the stirring rod and further promoting the uniformity and sufficiency of the solution reaction. The motor is threadedly connected to the first fixing nut, and the motor is fixedly connected to the outer wall of the spherical sealing cover by setting the first fixing nut, thereby increasing the stability of the overall mechanical mechanism.

[0022] In the present utility model, a feed inlet and a discharge outlet are respectively fixedly connected to the outer wall of the main body housing. Ball valves are arranged inside the feed inlet and the discharge outlet, the feed and discharge are controlled by the ball valves, the ball valves are fixedly connected to knobs, and the on-off of the ball valves is controlled by setting the knobs, enabling the operator to conveniently and quickly control the opening and closing of the ball valves, ensuring the precise management of the materials during the feeding and discharging processes. A cylinder is fixedly connected to a filter screen. By setting the filter screen to closely adhere to the lower surface of the equipment inside the mechanical equipment, during the discharging stage, the cylinder controls the filter screen to move upward, so that the solid sediment in the liquid adheres to the surface of the filter screen, thereby effectively separating the liquid from the solid and improving the filtering efficiency.
