Description

Technical Field

[0001] This utility model relates to the field of titanium concentrate technology, specifically to a high-frequency vibrating fine screen for titanium concentrate. Background Technology

[0002] The high-frequency vibrating fine screen for titanium concentrate is a device used to separate and screen fine particles in titanium ore (such as ilmenite, ilmenite, etc.).

[0003] According to a public disclosure (CN 208916350 U), a high-frequency vibrating fine screen feed box includes a feed box body, a horizontally arranged distribution pipe inside the feed box body, five equidistant material distribution ports on the lower front side of the feed box body, and five ore discharge holes corresponding to the five material distribution ports along the axial direction on the lower side wall of the distribution pipe. The distribution pipe is connected to the inlet pipe, and a blower is provided on both sides of the distribution pipe. The material distribution ports are conical, and a baffle is provided at the front end of the conical material distribution port. The advantages of this utility model are that the blower is installed on both sides of the distribution pipe, which avoids the accumulation of ore in the distribution pipe and the blockage of the ore discharge holes, ensuring the normal operation of the high-frequency vibrating fine screen and reducing the need for frequent cleaning and maintenance by operators; the conical material distribution port causes the ore to converge in the middle and avoids splashing to both sides; the baffle at the front end of the conical material distribution port forms a waterfall-like uniform ore supply to the high-frequency vibrating fine screen, improving the screening efficiency.

[0004] The aforementioned application, through the feeding box and the horizontally arranged component tube assembly within the feeding box, makes it impossible to pre-crush the raw materials, resulting in excessively large raw materials clogging the filter screen. Therefore, we propose a high-frequency vibrating fine screen for titanium concentrate that can pre-crush the raw materials. Utility Model Content

[0005] This invention proposes a high-frequency vibrating fine screen for titanium concentrate, which solves the problems mentioned in the above documents.

[0008] A rotating rod is fixedly connected inside the crushing box. A pressing plate is rotatably connected to the circumference of the rotating rod. A drive bar is fixedly connected to the side of the pressing plate. The pressing plate compresses the titanium concentrate so that the crushing roller can crush it better.

[0009] A push rod is fixedly connected to the circumferential surface of the rotating shaft, and a cylinder is fixedly connected inside the crushing box. A tamping rod passes through the circumferential surface of the cylinder, and the circumferential surface of the cylinder is rotatably connected to the inner wall of the tamping rod. The function of the push rod is to push the tamping rod to squeeze the extrusion plate, which in turn drives the extrusion bar to squeeze the titanium concentrate.

The end of the first torsion spring away from the rotating rod is fixedly connected to the side of the extrusion plate. A second torsion spring is fixedly connected to the circumferential surface of the cylinder.

[0011] The number of the rotating rod, extrusion plate, drive bar, cylinder, tamping rod, first torsion spring and second torsion spring is set to two and symmetrical to each other along the vertical central axis of the crushing box. The purpose of setting the number of the rotating rod, extrusion plate, drive bar, cylinder, tamping rod, first torsion spring and second torsion spring to two and symmetrical to each other along the vertical central axis of the crushing box is to better assist the crushing roller in crushing.

[0012] The bottom of the tamping rod is located on the displacement trajectory of the push rod, and the top of the driving bar is located on the displacement trajectory of the tamping rod.

The baffle is used to prevent the titanium concentrate from slipping during screening, and the second and third screens are used to further screen the titanium concentrate.

[0015] A collection box is slidably connected to the top of the placement plate. The purpose of the collection box is to collect the titanium concentrate that has been screened out by the third screen.

[0016] The number of fixing bars is set to two and they are symmetrical to each other along the vertical central axis of the placement plate. The number of baffles is set to several and they are arranged in a linear array along the vertical central axis of the fixing bars. The screen holes of the first screen, the second screen and the third screen are set to be one layer smaller than the last from top to bottom. The purpose of setting the screen holes of the first screen, the second screen and the third screen to be one layer smaller than the last from top to bottom is to separate titanium concentrate of different sizes.

[0017] The working principle and beneficial effects of this utility model are as follows:

[0018] 1. In this utility model, the rotation of the motor output shaft and the internal components such as the rotating shaft and crushing roller of the titanium concentrate crushing device work together to achieve the following: when the rotating shaft rotates, it drives the crushing roller to rotate, and when the push rod rotates, it drives the tamping rod to rotate along the cylinder. When the tamping rod rotates along the cylinder, it pushes the driving bar.

By starting the motor 44, when the output shaft of the motor 44 rotates, it can drive the rotating shaft 45 to rotate. When the rotating shaft 45 rotates, it will drive the crushing roller 46 to rotate. Then, the titanium concentrate in the crushing box 41 is fed through the feed port 42, so that it can be crushed by the rotating crushing roller 46. When the rotating shaft 45 rotates, it will drive the push rod 411 to rotate. When the push rod 411 rotates, it will drive the tamping rod 413 to rotate along the cylinder 412. When the tamping rod 413 rotates along the cylinder 412, it will push the driving bar 410. When the tamping rod 413 pushes the driving bar 410, the driving bar 410 will drive the extrusion plate 49 to rotate counterclockwise by the rotating rod 48, so that it can move closer to the crushing roller 46, so that smaller titanium concentrate can be crushed.
