Description

Technical Field

[0001] The utility model belongs to the technical field of zirconium carbide production, and more specifically, particularly relates to a grading filtering device for zirconium carbide production. Background Art

[0002] Zirconium carbide is a high-melting-point material with great hardness and an excellent high-temperature refractory material. Zirconium carbide is used as a raw material for solid propellant in rocket engines and is also used in the production of alloy steel. It is also a raw material for the production of metallic zirconium and zirconium tetrachloride, as well as a promising fine ceramic material.

[0003] Patent application number CN202021889270.X discloses a grading filtration device for zirconium carbide production, which solves the problem that the filter plates of the existing grading filtration devices for zirconium carbide production are easily clogged after repeated use, thereby reducing the overall filtration effect and greatly reducing the overall practicality of the device. The device includes a shell; a motor box, one side of the motor box is fixed to one side of the shell, and the bottom of the inner wall of the motor box is fixedly connected to a first motor through a fixing block. The utility model provides a graded filtering device for zirconium carbide production. By starting the second motor, the second motor can indirectly drive the first transmission wheel to rotate when it is started. Since the outer surface of the first transmission wheel is connected to the outer surface of the second transmission wheel by belt transmission, the first transmission wheel drives the second transmission wheel to rotate by belt transmission. The rotation of the second transmission wheel can indirectly drive the cam to rotate, that is, the T-block can be indirectly driven to shake up and down by the rotation of the cam, so that the up and down shaking of the second filter plate can be indirectly achieved by the T-block, so that the clogging of the second filter plate can be avoided, and the overall filtering effect of the device can be improved. However, the above technical solution only shakes the filter plate at the bottom to prevent clogging. When zirconium carbide of different particle sizes needs to be graded and filtered, a large amount of zirconium carbide accumulated on filter screens of different mesh sizes will also cause accumulation and clogging, affecting the filtration efficiency of zirconium carbide. In addition, some zirconium carbide particles are in powder form and will float in the filtering device during the shaking process. The staff needs to wait for the zirconium carbide to be completely deposited before taking out the zirconium carbide, which reduces the filtration efficiency.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a grading filtration device for zirconium carbide production is provided, in order to achieve a more practical purpose. Utility Model Content

[0027] The utility model provides a grading filtering device for zirconium carbide production, comprising a box body 1, a first mounting groove 2 is arranged inside the box body 1, and a plurality of pairs of first slide grooves 3 are symmetrically arranged on both sides of the first mounting groove 2 from top to bottom, a filter screen 4 is slidably installed between each pair of first slide grooves 3, a spring 5 is installed on one side of one of each pair of first slide grooves 3, and the other end of the spring 5 is connected to one side of the filter screen 4, a pair of second slide grooves 6 are symmetrically arranged at the bottom ends of both sides of the first mounting groove 2, a material receiving groove 7 is installed in the second slide groove 6, an opening 8 is arranged on one side of the box body 1 at a position close to each first slide groove 3, a mounting seat 9 is installed on the side of the box body 1 with the opening 8, a driving mechanism is installed in the mounting seat 9, a dust collecting port 10 is arranged on the other side of the box body 1, a dust collecting mechanism is installed on one side of the box body 1 at a position directly below the dust collecting port 10, and a feeding port 11 is arranged on the top of the box body 1.

[0028] The mesh size of the filter screen 4 increases from top to bottom, and the zirconium carbide is graded and filtered to filter and screen the zirconium carbide of different particle sizes.

[0029] Among them, the driving mechanism includes a second mounting groove 12, and the second mounting groove 12 is opened on a side of the mounting seat 9 close to the opening 8. A central shaft 13 is rotatably installed in the second mounting groove 12. A cam 14 is installed on the circumferential side of the central shaft 13 at a position parallel to each opening 8, and one side of the cam 14 is in close contact with one side of the filter screen 4. The cam 14 is driven to rotate by the rotation of the central shaft 13. Since one side of the cam 14 is in close contact with one side of the filter screen 4, the cam 14 continuously lifts the filter screen 4 during the rotation process. With the cooperation of the rebound effect of the spring 5, the filter screen 4 shakes back and forth, so that the accumulated zirconium carbide is shaken and filtered, thereby improving the filtering efficiency.

[0030] A motor 15 is installed at the top of the mounting seat 9 , and the output end of the motor 15 is transmission-connected to the central shaft 13 through a coupling. The motor 15 drives the central shaft 13 to rotate, thereby driving the cam 14 to rotate.

[0031] Among them, the dust collecting mechanism includes a dust collecting box 16, which is installed at the bottom end of one side of the box body 1, and a dust collecting net 17 is installed in the dust collecting box 16. An electric fan 18 is installed inside the dust collecting box 16 at a position directly below the dust collecting net 17. One side of the dust collecting box 16 is provided with an exhaust port at a position close to the output end of the electric fan 18, and a dust inlet duct 19 is installed at the top of the dust collecting box 16, and the dust inlet duct 19 is connected with the dust collecting port 10. When the electric fan 18 is turned on, the air in the dust collecting box 16 is discharged from the exhaust port, so that negative pressure is instantly generated in the dust collecting box 16, and then the air in the box body 1 enters the dust collecting box 16 with the scattered zirconium carbide powder through the dust collecting port 10 and the dust inlet duct 19 and adheres to the dust collecting net 17, so as to realize rapid recovery of the scattered zirconium carbide powder and improve the filtration efficiency.

[0033] A box door 21 is installed on one side of the box body 1 to facilitate the recovery of the zirconium carbide in the box body 1 .

[0034] The working principle of this embodiment is as follows: the staff first transports the zirconium carbide from the feed port 11 into the box body 1, and the zirconium carbide of different particle sizes passes through the filter screens 4 of different mesh sizes in turn and remains on the filter screens 4 of the corresponding mesh sizes. When more zirconium carbide accumulates on the surface of the filter screen 4, the staff turns on the motor 15, and the motor 15 drives the central shaft 13 to rotate, thereby driving the cam 14 to rotate. Since one side of the cam 14 is in close contact with one side of the filter screen 4, the cam 14 continuously lifts the filter screen 4 during the rotation process. With the cooperation of the rebound effect of the spring 5, the filter screen 4 shakes back and forth to achieve the purpose of removing the accumulated zirconium carbide. The zirconium carbide powder is shaken and filtered to improve the filtering efficiency. When the filtering is completed, some fine zirconium carbide powder is easily scattered in the box body 1 due to shaking. At this time, the staff turns on the electric fan 18 to discharge the air in the dust box 16 from the exhaust port, so that a negative pressure is instantly generated in the dust box 16, and then the air in the box body 1 carries the scattered zirconium carbide powder into the dust box 16 through the dust collecting port 10 and the dust inlet pipe 19 and adheres to the dust collecting net 17, so as to quickly recover the scattered zirconium carbide powder. The staff can recover the zirconium carbide powder in the dust box 16 by removing the disassembly plate 20.
