Description

Technical Field

[0001] This utility model belongs to the field of vibrating screens and relates to a protective vibrating screen for mineral processing. Background Technology

[0002] In industrial production, mineral processing is the core step in obtaining qualified smelting raw materials and other industrial ores. The core principle of this process is based on the differences in physical properties (such as density, magnetism, and particle size) and chemical properties of various minerals in the ore. Through pretreatment processes such as crushing and grinding, combined with various separation methods such as gravity separation, flotation, magnetic separation, and electrostatic separation, the useful minerals and gangue minerals are effectively separated. Furthermore, the various symbiotic useful minerals are broken down one by one, while harmful impurities in the ore are removed or reduced as much as possible, ultimately yielding raw materials that meet industrial production standards.

[0003] A Chinese utility model patent with publication number CN221832755U discloses a multi-stage mineral processing vibrating screen, which includes a mineral processing box. A screen plate is fixedly connected to the middle of the inner side of the mineral processing box. Several screen meshes are evenly arranged on the upper part of the screen plate. Motors are installed at the front and rear ends of the right side of the outer wall of the mineral processing box. The output end of the motor passes through the front and rear ends of the right side of the mineral processing box and is fixedly connected to a rotating shaft. Eccentric wheels are fixedly connected to the left and right ends of the outer side of the rotating shaft. Support columns are fixedly connected to the four corners of the bottom of the mineral processing box. Springs are fixedly connected to the outer top of the support columns. The bottom end of the support columns is fixedly connected to the top of the base plate.

[0004] The existing technology has the following technical defects:

[0005] When a screen is used to screen mineral materials under high-frequency vibration, some of the material may break off due to the material's inherent mass and inertia, and the screen's vibration imparts upward kinetic energy. For operators, this broken material can impact their bodies, especially vulnerable areas like the eyes and face, causing mechanical injury and posing a safety hazard. For the equipment, the broken material can also impact other parts of the vibrating screen or surrounding equipment, leading to increased wear and tear, reduced precision, and even shortened equipment lifespan over time. Utility Model Content

[0006] The technical problem to be solved by this utility model is to overcome the shortcomings of the existing technology and provide a protective vibrating screen for mineral processing.

[0007] The protective vibrating screen for mineral processing described in this utility model includes a frame and a double-layer screen box. Both discharge ends of the double-layer screen box are equipped with discharge plates. The frame is provided with support legs, and an extension frame is fixedly installed on the outside of the support legs. Shock-absorbing springs are installed on the support legs. The double-layer screen box is movably connected to the support legs through the shock-absorbing springs. A vibrator is installed on one side of the double-layer screen box. A flexible connection is fixedly installed on the drive end of the vibrator. A powerful motor is connected to the flexible connection. Protective components are provided on the extension frame and the double-layer screen box.

[0008] The first protective shell of the protective assembly is provided with a cleaning component, a first electric push rod is fixedly installed on the outer frame, a push block corresponding to the first electric push rod is provided on the first protective shell, and a second protective shell corresponding to the flexible connection is provided on the first protective shell.

[0009] The protective assembly includes two protective skins symmetrically installed below the first protective shell, and the protective skins are made of fluororubber.

[0010] A partition is fixedly installed on the protective skin, and a magnetic suction head is fixedly installed on the partition. A magnetic suction groove adapted to the magnetic suction head is opened on the double-layer screen box.

[0011] The cleaning assembly includes a first connecting block and a second connecting block fixed below the first protective shell. A threaded rod is rotatably connected between the first connecting block and the second connecting block. A slide beam is threaded onto the threaded rod, and a cleaning push rod is connected to the slide beam. A second gear is fixedly installed at one end of the threaded rod. The second gear meshes with a first gear, and a servo motor is connected to the first gear. The servo motor is fixed on the first protective shell.

[0012] The bottom of the slide beam is equipped with a second electric push rod, which is connected to a cleaning push rod.

[0013] The frame is equipped with a support platform, and a powerful motor is mounted on the support platform.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This utility model can prevent material fragments from flying up during the screening process through the first protective shell in the protective component, thereby preventing damage to surrounding equipment or people. The second protective shell can prevent the flexible connection from breaking due to wear and tear over a long period of use, thereby preventing damage to surrounding equipment or people. Through the first protective shell and the protective skin, the dust generated during screening can be reduced and diffused.

[0016] The first gear on the servo motor in the cleaning component drives the second gear to rotate, which in turn drives the threaded rod to rotate. This, in turn, causes the cleaning push rod, which is in close contact with the surface of the double-layer screen plate, to slide, pushing out the residual waste material and preventing the residual mineral material from corroding the equipment.
