Description

Technical Field

[0001] This utility model relates to the field of screening device technology, and in particular to a wet mineral screening device. Background Technology

[0002] Mineral screening is a fundamental step in mineral processing laboratories, permeating the entire process of process development, workflow optimization, and mineral grade control. Precise particle size classification can significantly improve mineral processing efficiency, reduce costs and resource waste, and provide a reliable basis for industrial scale-up. Laboratory screening equipment is mostly dry vibrating screens, suitable for screening large-particle minerals, but difficult to separate fine and micro-fine particles, and generates a lot of dust. Wet screening relies heavily on manual labor, resulting in low screening efficiency and high manpower consumption. Therefore, this paper presents a wet mineral screening device. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a wet mineral screening device. By vibrating the support frame, the minerals screened by the top screen flow into the sample collection trough and then into the next installation frame through the discharge port at the end of the sample collection trough, thus performing screening in sequence. This device can screen fine and micro-fine minerals, reduce dust pollution, improve screening efficiency, and overcome the shortcomings of existing technologies.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] As a further improvement of this utility model: the sample receiving slots installed at equal intervals are distributed along the axial direction of the support frame, and two adjacent sample receiving slots are distributed in an alternating manner, with the mesh count of the sieve increasing sequentially from high to low.

[0010] As a further embodiment of this utility model: the vibration component includes a U-shaped plate fixed to the lower end of the support frame, and a vibration motor is fixed to the upper surface of the horizontal section of the U-shaped plate.

[0011] As a further improvement of this utility model, the transverse frame is provided with fixing holes.

[0012] The beneficial effects of this utility model are as follows:

[0013] The vibration of the support frame causes the minerals screened off at the top of the screen to flow into the sample collection trough, and then into the next installation frame through the discharge port at the end of the sample collection trough, thus performing screening in sequence. This method can screen fine and micro-fine particles of minerals, reduce dust pollution, and improve screening efficiency. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Example 1, referring to Figure 1-4A wet mineral screening device includes a horizontal frame 1, a vertical frame 2 welded to one side of the top of the horizontal frame 1, a support frame fixed to the upper end of the horizontal frame 1 and the vertical frame 2, sample receiving slots 5 installed at equal intervals on the support frame, an installation frame 7 installed in the sample receiving slot 5 by a snap-fit ​​structure, a screen 8 provided at the bottom end of the installation frame 7, a discharge port 6 provided at one end of the sample receiving slot 5, a portion of the installation frame 7 and the screen 8 extending to the outside of the discharge port 6, a vibration component installed on the support frame, and a fixing hole 12 opened on the horizontal frame 1, through which the horizontal frame 1 can be fixed to the installation position by anchor bolts from the fixing hole 12.

[0021] The support frame includes two springs 3 symmetrically fixed at the top of the horizontal frame 1 and away from the end of the vertical frame 2. Two springs 3 are symmetrically fixed at the top of the vertical frame 2, and the support frame 4 is fixed at an angle to the top of the four springs 3.

[0022] A connecting rod 10 is fixed to the outer wall of the sample receiving groove 5, and the connecting rod 10 is welded to the inner wall of the support frame 4.

[0023] The sample receiving slots 5 are installed at equal intervals and distributed along the axial direction of the support frame 4. The two adjacent sample receiving slots 5 are distributed in an alternating manner, and the mesh count of the sieve 8 increases sequentially from high to low.

[0024] The snap-fit ​​structure includes a fixing block 13 fixed to the inner wall of the sample slot 5, a T-shaped insert 15 fixed to the outer wall of the mounting frame 7, and a T-shaped slot 14 provided on one side of the fixing block 13. The T-shaped insert 15 and the T-shaped slot 14 form a plug-in engagement to realize the quick installation and disassembly of the mounting frame 7.

[0025] The slurry is fed into the top mounting frame 7, and the screened minerals flow into the sample receiving trough 5. They then flow into the next mounting frame 7 through the discharge port 6 at the end of the sample receiving trough 5, and are screened in sequence. This process can screen fine and micro-fine minerals, reduce dust pollution, and improve screening efficiency.

[0026] Example 2 is an optimization based on Example 1, specifically:

[0027] The vibration assembly includes a U-shaped plate 9 fixed to the lower end of the support frame 4, and a vibration motor 11 (model YZS-5-4) is fixed to the upper surface of the horizontal section of the U-shaped plate 9.

[0028] By turning on the vibration motor 11, the eccentric block connected to it is driven to rotate and generate vibration, which in turn drives the U-shaped plate 9, the support frame 4 and the sample receiving groove 5 to vibrate. The vibration amplitude can be increased and the screening efficiency can be improved by the elastic support of the support frame 4 by the four springs 3.
