Description

Technical Field

[0001] This application relates to the technical field of solid screening devices, and particularly to a sieve basket fixing device. Background Art

[0002] When processing minerals or slag, there are often situations where metals are mixed with other solid substances and need to be screened. Common screening methods include electromagnetic adsorption and eddy current separation, etc. Among them, electromagnetic adsorption is only effective for metals that can be adsorbed, while eddy current separation can only process metals with larger particle sizes. For some metals with smaller particle sizes, the effect of eddy current separation is not good. Therefore, people have designed some machines to achieve the separation of metals and other solid substances through throwing and washing. For example, the Chinese patent with the application number 202321742856.7 discloses a metal throwing and washing machine, including a housing, a motor is installed in the housing, an eccentric wheel is installed on the output shaft of the motor, the eccentric wheel drives a connecting rod to drive the lifting frame to reciprocate up and down, a cross bar is arranged below the lifting frame, two vertical rods are installed on the cross bar, and a sieve mesh is installed between the lower parts of the two vertical rods. This device makes the sieve mesh reciprocate by the eccentric wheel driving the connecting rod, and uses water flow for throwing and washing, so that substances with different densities and particle sizes are stratified to facilitate the separation of metals. This device clamps the flanging of the sieve mesh through clip pieces. Under the impact of water flow, the flanging is prone to deformation, and the fixing method of the clip pieces is not easy to disassemble the sieve mesh. When the throwing and screening are completed, it cannot be quickly disassembled and replaced, affecting work efficiency. Therefore, a sieve basket fixing device is needed, which can effectively fix the sieve basket, prevent the sieve basket from deforming, and at the same time is convenient for disassembly. After completing the throwing and screening, a new sieve basket can be conveniently replaced. Utility Model Content

[0024] As Figures 1 to 4 shown, an embodiment of the present invention provides a sieve basket fixing device, including: a sieve basket connecting plate 1, the sieve basket connecting plate 1 is installed under the reciprocating mechanism of the screening device, and the sieve basket connecting plate 1 is in a "C" shape; a sieve basket bracket 2, both sides of the sieve basket bracket 2 are installed under the sieve basket connecting plate 1 through an extension block 5, and the middle part of the sieve basket bracket 2 is annular; a sieve basket 3, the sieve basket 3 is installed in the middle of the sieve basket bracket 2, and the flange on the upper part of the sieve basket 3 is attached to the middle part of the sieve basket bracket 2; wherein, a clamping groove 6 is provided on the upper part of the sieve basket bracket 2, a pressing block 7 is provided on the clamping groove 6, one end of the pressing block 7 is stuck in the clamping groove 6, the other end of the pressing block 7 is connected to the sieve basket bracket 2 through a first locking bolt 8, and the middle part of the pressing block 7 presses on the sieve basket 3.

[0025] The screening device is provided with a reciprocating mechanism, which drives the sieve basket fixing device and the sieve basket to make reciprocating motions in the vertical direction together, and cooperates with the scouring of water flow, so that the solid substances in the sieve basket are stratified more densely, and the classification of solid substances such as minerals and slag is realized.

[0026] When the screening device is working, the solid matter to be screened is placed in the screen basket 3, and the screen basket bracket 2 is fixedly connected to the screen basket connecting plate 1 through the extension block 5, so that the screen basket bracket 2 and the reciprocating mechanism of the screening device are hard-linked, and the circular hole in the middle of the screen basket bracket 2 matches the upper edge of the screen basket 3, so that the upper edge of the screen basket 3 is fixed by the screen basket bracket 2. After the first locking bolt 8 is tightened, the first locking bolt 8 is pressed on one end of the pressing block 7, and at the same time, the other end of the pressing block 7 is pressed through the slot 6, so that the middle part of the pressing block 7 effectively fixes the upper part of the screen basket 3, so that the screen basket 3 can move with the screen basket bracket 2.

[0027] Specifically, connecting ears 9 are provided on both sides of the upper part of the screen basket bracket 2, the lower part of the connecting ears 9 is fixedly connected to the screen basket bracket 2, the middle part of the connecting ears 9 is hinged to the lower part of the extension block 5, and a plurality of limiting holes 10 are provided on the upper part of the connecting ears 9, so that the screen basket bracket 2 can be deflected at a certain angle relative to the extension block 5 to meet the screening requirements of different solid materials.

[0028] In a specific embodiment, a second locking bolt 11 is provided on the extension block 5, and a limiting hole 10 is distributed in an arc shape on the upper part of the connecting ear 9, and the center of the arc is located on the axis of the second locking bolt 11. One end of the second locking bolt 11 passes through the extension block 5 and is inserted into the limiting hole 10. After loosening the second locking bolt 11, the second locking bolt 11 is separated from the limiting hole 10, so that the screen basket bracket 2 can be rotated relative to the extension block 5. After the angle adjustment is completed, the second locking bolt 11 is rotated so that the second locking bolt 11 is inserted into the limiting hole 10, thereby locking the connecting ear 9 to prevent the screen basket bracket 2 from loosening when throwing the screen.

[0030] In a specific embodiment, Figure 4As shown, a slope portion 13 is provided at one end of the pressing block 7, and a slotted portion 14 is provided at the other end. The slope portion 13 is stuck in the slot 6, and the first locking bolt 8 is inserted into the slotted portion 14 and pressed on one side of the slotted portion 14. After loosening the first locking bolt 8, the pressing block 7 can be pulled from the side to separate the slotted portion 14 from the first locking bolt 8, so that the pressing block 7 can be pulled out. At this time, the screen basket 3 and the screened solid matter in the screen basket 3 can be taken out together, and then a new screen basket 3 can be placed, and the solid matter to be screened is added, and the pressing block 7 is inserted into the slot 6, and the slotted portion 14 is inserted into the lower part of the first locking bolt 8. After tightening the first locking bolt 8, the pressing block 7 can be locked to achieve effective fixation of the screen basket 3.
