Description

Technical Field

[0001] This utility model relates to the field of cryolite production technology, specifically a drying device for cryolite production. Background Technology

[0002] Cryolite (Na3AlF6) is a double salt of sodium fluoride and aluminum fluoride, also known as sodium hexafluoroaluminate. In aluminum smelting, cryolite is an indispensable flux in aluminum electrolysis because, in addition to dissolving alumina, it possesses several essential properties, such as not containing elements more positively charged than aluminum, good stability (it does not decompose, volatilize, or deliquesce under normal conditions), a higher melting point than aluminum, good electrical conductivity, and energy savings. Furthermore, cryolite is widely used as a wear-resistant filler in rubber and grinding wheels, an enamel opacifier, a glass opacifier, a metal flux, and an insecticide for crops.

[0003] Chinese utility model patent CN221183885U discloses a drying device for cryolite production, comprising: a base plate, two sets of support rods on both the left and right sides of the base plate, and a drying chamber on the side where the upper ends of the four sets of support rods are close together. A heating wire is installed on the lower side inside the drying chamber. A rotating motor drives a pulley to rotate, thereby rotating a path rod, which in turn moves a moving strip. This allows a cleaning block to sweep away impurities from the cryolite. The cleaning removes surface stains, dust, and debris, making the cryolite look more beautiful and attractive. By turning on the drive motor, rotating rods at both ends are rotated, and a crank drives a connecting rod to shake, causing the connecting rod to shake the drying chamber hinged to the other end. Protective pads protect the cryolite, allowing impurities swept from the surface of the cryolite to be screened out through holes in the surface of the drying chamber.

[0004] However, the above-mentioned patent still has the following shortcomings in actual use: the impurities swept off the surface of the cryolite are screened out through the holes opened on the surface of the drying box, and the screened impurities accumulate inside the drying box, making it difficult to remove these impurities in the future. Utility Model Content

[0005] The purpose of this invention is to provide a drying device for cryolite production, in order to solve the problem mentioned in the background art that the impurities screened out accumulate inside the drying chamber and are difficult to remove in the future.

[0006] The technical solution of this utility model is:

[0007] A drying device for cryolite production includes a base plate, a drying chamber, a partition, an inclined plate, a heating tube, a screening assembly, a cleaning assembly, an opening and closing assembly, a collection box, two guide rods, and two guide blocks. The two guide rods are symmetrically arranged on the top of the base plate, and the two guide blocks are slidably mounted on the two guide rods. The outer walls of both sides of the drying chamber are connected to the two guide blocks. The partition is installed inside the drying chamber and has multiple through holes. The inclined plate is installed inside the drying chamber and is located below the partition. A ventilation groove is provided at the top of the inclined plate. The heating tube is installed at the bottom of the drying chamber. A discharge groove communicating with the interior is opened on the outer wall of the bottom of the drying chamber. A channel corresponding to the discharge groove is provided on the outer wall of the bottom of the drying chamber. The screening assembly is installed on the top of the base plate, with its top extending to the bottom of the drying chamber. The cleaning assembly is installed at the top of the interior of the drying chamber. The opening and closing assembly is installed on the outer wall of the drying chamber and blocks the discharge groove. The collection box is installed on the top of the base plate and is located diagonally below the channel.

[0008] Furthermore, the screening assembly includes a rotating motor, a chain, and two screening components. The two screening components are symmetrically arranged on the top of the base plate, and the top ends of the two screening components extend to the bottom of the drying chamber. Each screening component includes a rotating seat, a rotating shaft, a rotating cam, a sprocket, a support, and an abutting wheel. The rotating seat is located on the top of the base plate, the rotating shaft is rotatably mounted inside the rotating seat, the rotating cam is mounted on the rotating shaft, the sprocket is mounted on the end of the rotating shaft, the support is located at the bottom of the drying chamber, and the abutting wheel is rotatably mounted inside the support, with the bottom end of the abutting wheel abutting against the top end of the rotating cam. The rotating motor is horizontally arranged on the outer wall of the rotating seat in one of the screening components, and the output shaft of the rotating motor is connected to the rotating shaft in one of the screening components. The chain is sleeved on the outside of the sprockets in both screening components.

[0009] Furthermore, the cleaning assembly includes a cleaning plate, a screw, a screw sleeve, a drive motor, and two guide rails. The two guide rails are symmetrically arranged at the top of the interior of the drying chamber. The cleaning plate is slidably mounted on the two guide rails. The bottom of the cleaning plate is provided with multiple brushes. The screw is rotatably mounted inside the drying chamber. The screw sleeve is fitted onto the screw and is threadedly engaged with the screw. The bottom of the screw sleeve is connected to the top of the cleaning plate. The drive motor is horizontally mounted on the outer wall of the top of the drying chamber, and the output shaft of the drive motor is connected to the screw.

[0010] Furthermore, the opening and closing assembly includes an opening and closing plate, a mounting frame, an electric push rod, and a pusher. The opening and closing plate is slidably mounted on the bottom outer wall of the drying oven. The mounting frame is mounted on the drying oven. The electric push rod is vertically mounted on the outer wall of the mounting frame. The pusher is mounted on the output end of the electric push rod and is connected to the outer wall of the opening and closing plate.

[0011] Furthermore, the top of the collection box is equipped with a U-shaped baffle.

[0012] Furthermore, the bottom of the brush is attached to the top of the partition.

[0013] This utility model provides an improved drying device for cryolite production, which has the following improvements and advantages compared with the prior art:

[0014] Firstly, this invention places cryolite on a partition, and then the screening component drives the drying chamber and two guide blocks to reciprocate up and down on two guide rods. The drying chamber causes the cryolite to reciprocate up and down, creating a shaking motion that shakes off impurities from its surface. At the same time, the cleaning component cleans the surface of the cryolite, removing any impurities adhering to it. The shaken and swept impurities fall onto an inclined plate through multiple through holes. These impurities roll off the inclined plate, and the hot air generated by the heating element enters the surface of the cryolite through the ventilation slots and through holes to complete the drying process. The periodic opening and closing component keeps the discharge slot open, and the impurities on the inclined plate fall into the collection box through the channel for collection. This eliminates the need for manual removal of impurities accumulated inside the drying chamber, making it very convenient.

[0015] Secondly, this utility model uses an electric push rod to drive the push frame and the opening and closing plate to move upward. The upward movement of the opening and closing plate opens the discharge trough, making it convenient for impurities on the inclined plate to fall into the collection box for collection through the discharge trough and channel.
